Abstract
The utility model relates to the technical field of printers, in particular to a strike-through board cleaning device of a circuit board solder paste printer. The strike-through board cleaning device of the circuit board solder paste printer comprises a workbench, a conveying belt and a strike-through board, and is characterized in that a push block is arranged on the front side of the workbench, a roller is arranged on the front side of the push block, and the push block and the roller are covered with cleaning paper. Compared with the prior art, the cleaning device special for cleaning the strike-through board is additionally arranged on the circuit board solder paste printer, when the number of the times of printing reach a certain value, the cleaning device is started, unnecessary solder paste on the back face of the strike-through board is removed, no gap exists between the strike-through board and a circuit board, and the percent of pass of the coated circuit board is improved.
Description
Technical field
The utility model relates to printer technology field, specifically a kind of print through board cleaning device of circuit board stencil printer.
Background technology
Traditional stencil printer does not have the cleaning device matching with print through plate, in the process of paste solder printing, circuit board is when being applied by tin cream, and unnecessary tin cream can remain in the back side of print through plate, in the course of time, residual tin cream amount can increase, cause like this circuit board and print through plate directly to have gap, cause scraper plate that tin cream is coated on circuit board, the thickness of tin cream increases, directly cause on circuit board tin cream thickness blocked up and defective, increased the scrappage of circuit board.
Summary of the invention
The utility model is for overcoming the deficiencies in the prior art, on stencil printer, increase special in the clean cleaning device of print through plate, when print pass reaches certain numerical value, open cleaning device, the unnecessary tin cream of print through backboard face is removed, reaching print through plate and circuit board does not directly have gap, and the circuit board qualification rate applying out improves.
For achieving the above object, design a kind of print through board cleaning device of circuit board stencil printer, comprise workbench, conveyer belt, print through plate, it is characterized in that: the front side at workbench is provided with pushing block, the front side of pushing block is provided with cylinder, on described pushing block and cylinder, wraps and is provided with cleaning paper.
Described pushing block and the upside of the cleaning paper between cylinder are provided with sparge pipe.
The below of described pushing block is provided with guide rail.
Described sparge pipe is provided with some apertures.
The utility model compared with the existing technology, on stencil printer, increase special in the clean cleaning device of print through plate, when print pass reaches certain numerical value, open cleaning device, the unnecessary tin cream of print through backboard face is removed, reaching print through plate and circuit board does not directly have gap, and the circuit board qualification rate applying out improves.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Referring to Fig. 1,1 is workbench, and 2 is print through plate, and 3 is conveyer belt, and 4 is pushing block, and 5 is sparge pipe, and 6 is cylinder, and 7 is cleaning paper.
The specific embodiment
With reference to the accompanying drawings the utility model is described further below.
As shown in Figure 1, in the front side of workbench 1, be provided with pushing block 4, the front side of pushing block 4 is provided with cylinder 6, on described pushing block 4 and cylinder 6, wraps and is provided with cleaning paper 7.
The upside of the cleaning paper 7 between pushing block 4 and cylinder 6 is provided with sparge pipe 5.
The below of pushing block 4 is provided with guide rail.
Sparge pipe 5 is provided with some apertures.
At stencil printer when printed circuit board (PCB) reaches the quantity of setting, while there is no circuit board on the inductor induction conveyer belt 3 on conveyer belt 3 sides of stencil printer, stencil printer is controlled conveyer belt 3 and is quit work, open cleaning device, sparge pipe 5 is to spraying cleaning liquid on cleaning paper 7, after having sprayed, pushing block 4 drives cleaning paper 7 to advance to print through plate 2 directions, until shift the rear portion of stencil printer onto, then pushing block 4 resets, cylinder 6 furls unnecessary cleaning paper 7, and clean complete, stencil printer starts normal operation.
