Spray process in small production line
Technical field
The present invention relates to the spray-painting production line technology that the parts such as shell to products such as mobile phone, digital camera, MP3 spray, particularly be fit to the spray-painting production line technology of small lot batch manufacture.
Background technology
Raising along with production technology, to mobile phone, digital camera, the method of the spray paint of the shell of products such as MP3 has also all realized streamline production, streamline is produced to enterprise and has been brought greater efficiency, it includes following operation successively spray-painting production line in the streamline production of the spray paint of existing phone housing: part on the workpiece, removal moisture drying, electrostatic precipitation, the priming paint spraying, the priming paint levelling, hot setting, electrostatic precipitation, the colored paint spraying, the colored paint levelling, hot setting, electrostatic precipitation, spray paint, the finish paint levelling, the UV photocuring, the finish paint baking, cooling, following part, such product is got off and is just needed long time, have because all process steps of its inside all drives on a carrier chain, the needed time of each procedure all is to finish on the carrier chain of motion, it needs 15 minutes as hot setting, then carrier chain just need be the indoor operation of hot setting 15 minutes, so this spray-painting production line whole production line is very long, it only is fit to produce in enormous quantities, once it is less to need product processed quantity to compare, then also all operation startups of this production line, have only to last operation of a last product and finish, just can stop carrier chain, so not only influenced the processing of other products, and very take electricity, increased very high cost to production.
Summary of the invention
The present invention has overcome the deficiency that prior art exists, and a kind of simple in structure, easy to operate, spray process in small production line of being particularly suitable for small lot batch manufacture is provided.
Realize above-mentioned purpose, the present invention adopts following technical scheme: a kind of spray process in small production line, it is characterized in that: include following operation: part on the workpiece, removal moisture drying, electrostatic precipitation, spraying, levelling, UV light is solid or hot setting, workpiece under part, solid and the hot setting of wherein said UV light in a multi-function device, this multi-function device according to setup parameter select automatically UV light consolidate and hot setting between a kind of operation.Be provided with like this, we have just reduced the process flow of a lot of repetitions, as in the background technology in order to produce in enormous quantities, some same operations are provided with two or three, whole production line is just very long like this.In addition we solid and hot setting operation is arranged in the device UV light, its selects to adopt UV light still hot setting operation admittedly automatically according to the technical parameter that configures, compact so again this production line has reduced production cost.
The further setting of the present invention is: part on the described workpiece, removal moisture drying, carrier chain in electrostatic precipitation and the spraying process is same carrier chain, carrier chain in the solid or hot setting operation of described UV light is independent carrier chain, after the operation of front is covered like this, entering can be independent in the solid or hot setting operation of UV light, particularly the UV light time solid or that hot setting is used is long, so separately, carrier chain in the solid or hot setting operation of UV light can shut down, other work continue, and part on the workpiece, removal moisture drying, carrier chain in electrostatic precipitation and the spraying process normally moves, further compact this production line.
Of the present invention further the setting again is: solid operation of described levelling operation and UV light and hot setting operation are in same multi-function device, after in this multi-function device, passing through described hot setting operation, multi-function device can be transported to processed product the electrostatic precipitation operation, after the solid operation of described UV light, multi-function device can be transported to processed product part operation under the workpiece.Like this, can reuse some operations, save cost, compact this production line.
Below in conjunction with accompanying drawing the present invention is further described:
Description of drawings
Fig. 1 is an embodiment of the invention schematic flow sheet.
The specific embodiment
As shown in Figure 1, a kind of spray process in small production line, in an embodiment of the present invention, include following operation: part on the workpiece, removal moisture drying, electrostatic precipitation, spraying, levelling, solid or the hot setting of UV light, part under the workpiece, solid and the hot setting of wherein said UV light is in a multi-function device 1, this multi-function device 1 is selected a kind of operation between the solid and hot setting of UV light automatically according to setup parameter, in particular, it is exactly the requirement that this multi-function device 1 satisfies the solid and hot setting operation of UV light simultaneously, but he can only select one to come work, controls according to the setting of multi-function device 1 inner parameter in the selection in this time.The present invention adopts such method to set up, has just significantly reduced the process flow of a lot of repetitions, as in the background technology in order to produce in enormous quantities, some same operations are provided with two or three, whole production line is just very long like this.In addition we solid and hot setting operation is arranged in the device UV light, its selects to adopt UV light still hot setting operation admittedly automatically according to the technical parameter that configures, compact so again this production line has reduced production cost.Here we need to prove, the particular content of above-mentioned described operation and effect all are the same with existing technology, so we just are not further described these.
In an embodiment of the present invention, carrier chain on the described workpiece in part, removal moisture drying, electrostatic precipitation and the spraying process is same carrier chain, here we underline the effect of carrier chain, it is that the transmission product to be processed promptly needs the product that sprays for a carrier chain, makes it to be transported to the other end from an end; Carrier chain in the solid or hot setting operation of described UV light is independent carrier chain, the carrier chain here can think to have the carrier chain of transfer function, also can think to settle parts of the product that is transmitted by the carrier chain in part, removal moisture drying, electrostatic precipitation and the spraying process on the workpiece; The purpose of She Zhiing is like this, after part, removal moisture drying, electrostatic precipitation and spraying process are covered on the workpiece, processed product is transported in the solid or hot setting operation of UV light, because the UV light time solid or that hot setting is used is long, processed product is transported to that its carrier chain can shut down in the solid or hot setting operation of UV light, and UV light is solid or other function of hot setting operation continues; And the carrier chain in part, removal moisture drying, electrostatic precipitation and the spraying process normally moves on the workpiece, further compact this production line.
In an embodiment of the present invention, solid operation of described levelling operation and UV light and hot setting operation can be arranged in the same multi-function device 1, and the levelling operation also can not be arranged in the multi-function device 1 certainly, and this often sets according to the demand of reality.The concrete work of this small-sized spray-painting production line is, process is described after the hot setting operation in this multi-function device 1, multi-function device 1 can be transported to the electrostatic precipitation operation to processed product once more, if processed product is through after the solid operation of UV light, then multi-function device 1 can be transported to part operation under the workpiece to processed product, descends the part operation can comprise finish paint baking and last cooling here.Can reuse some operations by such scheme, save cost, compact this production line.
