Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to an upper pressure adsorption laser processing stage. Background Technology

[0002] During laser processing, the chip needs to be placed on a processing platform such as a vacuum chuck.

[0003] A search revealed a Chinese patent publication number, CN218123362U, which discloses a laser device for chip processing, belonging to the field of chip technology. The device includes a base plate with a controller and a flipping structure on its top. The bottom of a telescopic push rod is fixedly connected to an adjusting frame, and the bottom end of a movable frame is fixedly connected to the top end of the telescopic push rod. A motor is located at the top of the movable frame, and the inner wall of a connecting rod is fixedly connected to the outer wall of a bevel gear set. This laser device for chip processing, through its flipping structure, allows users to process chips from both sides to ensure optimal processing results. This saves time and improves processing efficiency while maintaining quality by preventing chips from falling and affecting subsequent processing. Ultimately, it increases both the efficiency and quality of chip production.

[0004] In summary, the problem with the existing technology is that the conventional method is usually direct laser processing. During the processing, the chip that is peeled off first will move, which will affect the processing of adjacent chips and lead to a decrease in the overall yield.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a pressure adsorption laser processing stage, which would have greater industrial application value. Utility Model Content

[0029] like Figures 1-3 As shown, a pressure adsorption laser processing stage includes a DD motor 1, a suction cup base 2, and a vacuum suction cup 3, wherein the vacuum suction cup 3 is a ceramic suction cup. The suction cup base 2 is mounted on the DD motor 1, and the vacuum suction cup 3 is mounted on the suction cup base 2. At least one sealing ring 5 is installed between the vacuum suction cup 3 and the suction cup base 2.

[0030] An upper pressure plate 7 is set directly above the vacuum suction cup 3. A quartz 6 is installed in the central groove of the upper pressure plate 7. The quartz 6 is glued to the central groove of the upper pressure plate 7. The product 4 is placed on the vacuum suction cup 3 directly below the quartz 6.

[0031] Several pressure blocks 10 are evenly distributed along the circumference on the suction cup base 2 outside the upper pressure plate 7. An adjusting screw 11 is installed in the vertical direction inside the pressure block 10. The adjusting screw 11 can move up and down inside the pressure block 10 and contact the upper pressure plate 7 below.

[0032] The pressure block 10 includes a vertical end and a horizontal end. The vertical end is mounted on the suction cup base 2 in a vertical direction, and the horizontal end is mounted on the inner top of the vertical end in a horizontal direction. A threaded sleeve 12 is installed vertically inside the horizontal end of the pressure block, and an adjusting screw 11 is screwed vertically into the internal thread of the threaded sleeve 12. The threaded sleeve 12 is screwed into the internal thread of the horizontal end of the pressure block.

[0033] A dial indicator 8 is mounted on the bottom of the suction cup base 2 directly below at least one pressure block 10 via a dial indicator fixing block 9, and the pin on the top of the dial indicator 8 is in contact with the bottom of the upper pressure plate 7 above.

[0034] The positional and connection relationships between the components of this utility model are as follows:

[0035] The suction cup base 2 is mounted on the DD motor 1 with screws. A sealing ring 5 is placed in the central groove above the suction cup base 2. The vacuum suction cup 3 is positioned on the suction cup base 2 by the sealing ring 5. The product 4 is placed on the vacuum suction cup 3. The quartz 6 is glued to the central groove of the upper pressure plate 7 and placed on top of the product 4, with the quartz surface pressing against the product 4. The dial indicator fixing block 9 is mounted on the back of the flange of the suction cup base 2 with screws. The pin of the dial indicator 8 passes through the flange hole of the suction cup base 2 and is clamped and fixed by the dial indicator fixing block 9. The threaded sleeve 12 is screwed into the threaded hole of the pressure block 10, and the adjusting screw 11 is screwed into the internal thread of the threaded sleeve 12. The entire assembly is then mounted on the front of the flange of the suction cup base 2 with screws.

[0036] The working principle and process of this utility model:

[0037] First, place product 4 above vacuum suction cup 3, and turn on the vacuum to adsorb and fix product 4. Quartz 6 is attached to the center groove of upper pressure plate 7 and placed above product 4, with the quartz surface pressing against product 4. Loosen the clamping screws of dial indicator fixing block 9, adjust the overall height of dial indicator 8 to ensure that the pin of dial indicator 8 is pressed against the back of the flange of suction cup base 2, and set all three dial indicators 8 to zero. Install three adjustable pressure blocks 10 on the front of the flange of suction cup base 2, ensuring that the adjusting screw 11 is directly above the pin of dial indicator 8, and screw the ball head of adjusting screw 11 into the V-groove of the flange of suction cup base 2; circumferentially unscrew the three adjusting screws 11 downwards to press down upper pressure plate 7, ultimately pressing down on product 4. The amount of downward pressure is observed by the readings of the three dial indicators 8.

[0038] This invention involves adsorbing the chip onto a carrier stage, then placing it on a quartz plate for pressing. Laser processing is performed through the quartz, ensuring the chip remains stationary during the process. The structure is simple, the pressure applied to the product is visualized, and adjustments and tests are convenient, allowing for comparison of processing effects under different pressure conditions.
