Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laser processing device, which is equipped with a mechanism that quickly adjusts the focal position by numerical control according to the thickness of the WC workpiece, and furthermore, supports nozzle replacement. The purpose of the present invention is to provide a laser processing device equipped with nine mechanisms that improve operability and safety by separating it from the optical system and making it detachable so that it can be used for ink printing.

With conventional laser processing machines, it took a lot of time to replace the condensing lens, and it was also difficult to adjust the nozzle to adjust the focus position and the thickness of the workpiece. It was a tedious task.

Honjitsu-Hiro: This was done in light of the above-mentioned problems, and it has undergone significant improvements in terms of operability and safety.

As an embodiment of the present invention, Fig. 1 is a full square drawing showing only the irradiated part perpendicular to the workpiece # of the laser machining device. Both figures are shown.

The back side of the paper in III, the left side of this mirror plate in Figure 2, the 3rd
In the figure, the right side of the figure shows the main body of the laser oscillation device. 3 is a nine-two case placed on the front element 111, and a laser beam generated by an oscillator and containing a built-in isoka energy is guided horizontally into this case, and is directed vertically by a nine-reflector (not shown). Orientation changed, ore layer 5
After that, it goes to the condensing lens that blocks the ridge. This is a hollow body bracket that supports the #7#i case 3 and guides the laser beam.

As mentioned above, the position where the laser beam irradiates the workpiece material and processes it is 111 degrees from the oscillator board, so all the equipment and devices described later are in the form of a cantilever from the #i board above. must be supported. In this device, there are two systems of support mechanisms, and the fs1 bracket 9 has the same dimensions as the middle 9 Ijs Noracket, and it is visible from the original image and fixes 2313.13, which will be described later, in the center of the left and right sides. There is. 1I1
The 2 bracket 15°Is is divided into two parts, left and right.
As is clear from No. 211, each of them is equipped with a cylinder 17 and 17 which stores force downward, such as a plate valve device to be described later, at a position where the optical axis of the laser beam and the axis are aligned with each other.

The first bracket 9 has a 2ilV9 laser beam 113 perpendicular to the rear side of the straight laser optical axis when viewed from the original image.
As shown in WAK, K11l is fixed. In this cylinder company, the cylinder chamber is composed of the large-diameter cylinder 1i21 and the small-diameter cylinder chamber 2302, and the piston rod 27 wire of the large-diameter piston 25 sliding in the large-diameter cylinder chamber, and the outside of the small-diameter piston 2S of the small-diameter cylinder chamber. The piston ridge of the small-diameter piston has the same diameter as the piston, and extends downward for a long length to form a piston 33 within the second cylinder 31.

The bottom of the second cylinder has a screw cap 3SK, and an upper enit support plate 37 is held between the second cylinder and the screw cap.

The upper end is connected to the bellows and the circle @SS is screwed $$4.
The worm wheel 43 is supported by bearings 45 and 45 on its upper and lower sides and is rotatable. νnda 49, 41
It is supported by (b) 1 and is rotatable. A worm gear 1jllK bevel gear 51 is fixed, and this bevel gear is fixed to the - of the D and C motors 5s and meshes with the bevel gear 53 of the nine.

As is clear from the mechanism aSS, from these worm gears and worm wheels to the C servo motor,
A bracket 57 is fixed to the upper unit board 59, and a bracket 63 for fixing the upper end of the race cylinder dial gauge 61 is fixed, and the rear end of this bracket is provided at the connection with the upper work knit board. Due to the round guide boot ta @S with a vertically closed body, it is able to slide freely only in the vertical direction but prevents rotation.
The razu-enkazu itself does not rotate at all, but moves up and down. Note that 67 is the central part of the tip of the dial gauge, and since it is one body with the upper unit base 1 [59, the vertical movement of the race cylinder is directed by the dial gauge.

In the present invention, a condenser lens 69, which is called an optical system,
The upper part is knitted, and the nozzle 1 and the assist chair L plate valve roller device 1 are placed below it.
The main feature of this unit is that the lower unit is removable.

First, three clamp nails 79 protrude from the upper surface of the lower unit shown in Figure 411(A), and the tapered attachment/detachment opening 81 provided in the disk Q3 shown in No. 411(A) is inserted into the counterfeit money. It has a long arc-shaped hole with a diameter that allows the clamp nail to be inserted, and a hole with a small diameter that allows the clamp nail to pass through. The overhanging part extends uphill towards the narrow path.

Therefore, the large diameter hole KIIP of the attachment/detachment opening is a clamp nail, and the lever 85 (1st-.2°311) integrated with the circle 1183 is inserted.

Upper S enin) Klflli! ! When it is determined, it becomes . Figure 4 (to) shows the state in which the rounded limit switch $7, which ensures that the upper and lower units are connected, is in contact with the dog 8g provided at 1sK in the circle 1183. In addition, in the 311th unit, a spring-like spring 91 is inserted into the threshold of the upper unit and the lower unit. In addition, the lower end of the lower unit is provided with a KFi plate pushing plate valve device 75, and a roller 93 in direct contact with the plate is mounted on the bracket 9.
5, and the first wrinkle bracket is provided on the lower part) and is rotatable by a bearing 97.

Inside the lower unit 11 is the nozzle box 1 described above, and the nozzle outer periphery 'NK is provided with a threaded part 99, and a nine-turn nozzle adjustment ring 161 is provided in preparation for the internal thread l11 that screws into the scissor threaded part 41.1. It is. The hollow space inside the nozzle is the above-mentioned assist gas chamber 73, the pressure of which can be measured and monitored with a pressure gauge 103.

Reference numeral 105 is an emergency stop sensor that extends from the lower end of bracket 9 of ll51 to both sides of the lower unit, and is used in case a carriage, etc. that conveys the workpiece during papermaking or work approaches the lower unit abnormally. It senses this and takes emergency measures to stop the material feeding device.

Also, as seen in FIGS. 1, 3, and 5, when viewed from the original image, the knob 107 is located at the bottom of the right end, and along the lower edge of the first bracket 9, there is a 1gx cylinder. 31, where it rotates the bevel gears 109 and 111, and rotates the bevel gear 111 and the internal threaded circle $1113. It has a threaded part that screws into the internal thread of this cylinder,
The shaft rod 115, which also serves as the shaft of the bevel gear 111, changes its position up and down by rotating the knob simultaneously, and
The function is to determine the lowest position of the screw cap 35. Reference numeral 117 in FIG. 5 is a locking knob for adjusting the lowermost position of the screw cap and locking it at the end.

As mentioned above, the present invention is based on the upper unit and the lower unit).
Classified into K, the lower unit can be attached and detached from the upper unit very easily, and the condensing lens can be exchanged and enlarged safely.
In addition, changing the focus position according to changes in the thickness of the workpiece can be numerically controlled using the D and C motors, and everything such as the height of the nozzle from the workpiece can be adjusted externally. There is also a safety device for checking the attachment of the lower part knit.It is equipped with 1° and 2 cylinders, multiple dogs on the left and right sides of the upper unit board, and a lint switch installed on the front panel of the main unit. In addition to the processing position closest to the workpiece, the upper and lower units can be positioned at at least two arbitrary positions at once, and are equipped with an air buffering device. 1 Furthermore, a pair of left and right temporary holding cylinders is provided at the position of the laser light beam, and the roller It (111 and It is constructed so that it can follow sudden changes in the thickness of the material to be processed.
