DETAILED DESCRIPTION

[0015] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0016] Please refer to the attached Figure 1-3The embodiment of the present application provides a coating 210 desorption treatment device, including a frame and a support platform 110 and an absorption compensation device arranged on the frame, the support platform 110 is used to support the coating 210 substrate, the coating 210 substrate includes a metal base layer 230, a coating 210 and a first absorption layer 220, the coating 210 is located on the top surface of the metal base layer 230, and the first absorption layer 220 is located on the top surface of the metal coating 210. Among them, the coating 210 can be but not limited to a PVD coating 210, such as an AlCrN coating 210, the material of the metal base layer 230 can be but not limited to titanium alloy, etc., and the first absorption layer 220 can be but not limited to a black tape layer. The coating 210 desorption treatment device also includes a laser shock device, which performs laser shock treatment on the coating 210 substrate according to a set path and a set overlap rate between adjacent laser shock positions 310. The laser shock position 310 is the position where the laser spot is irradiated on the coating 210 substrate. The portion of the first absorption layer 220 covering the overlapping portion between two adjacent positions to be laser shocked is vaporized and removed after the laser shock is applied to the first position to be laser shocked, so that the first absorption layer 220 has a covering gap on the second position to be laser shocked. The covering gap is the overlapping portion between two adjacent positions to be laser shocked, that is, the position to be supplemented. The absorption compensation device includes an absorption compensation member, which can be movably arranged to cover the position to be supplemented on the first absorption layer 220, thereby increasing the coverage area of ​​the absorption layer on the non-first position to be laser shocked, increasing the impact strengthening effect of the laser on the coating 210 substrate, and increasing the coating 210 desorption effect of the coating 210 desorption treatment device.

[0017] In some embodiments of the present application, the absorption compensation member is an absorption compensation film 170, which can be black in color to have a better absorption effect on laser energy. The absorption compensation device also includes a conveying mechanism, which is arranged on both sides of the carrier 110, and the absorption compensation film 170 is arranged on the conveying mechanism and a part of the absorption compensation film 170 covers the top surface of the first absorption layer 220, wherein the absorption compensation film 170 and the first absorption layer 220 together form the absorption layer of the metal substrate 200. The absorption compensation film 170 moves along the first direction under the drive of the conveying mechanism, and during the movement, there is always a part of the absorption compensation film 170 covering the surface of the first absorption layer 220, so that the absorption compensation film 170 can sequentially cover the position to be supplemented formed after each laser shock treatment along the first direction, thereby improving the efficiency of laser shock.

[0018] The thickness of the absorption compensation film 170 and the first absorption layer 220 may be the same or different. For example, the thickness of the absorption compensation film 170 is less than the thickness of the first absorption layer 220. The material of the absorption compensation film 170 may be, but is not limited to, black PVC, PET, etc. The first absorption layer 220 includes a base film layer and a glue layer coated on one side of the base film layer.

The width of the absorption compensation film 170 is greater than the laser spot diameter, preferably more than twice the laser spot diameter.

[0019] The laser impact path on the metal substrate 200 may be, but is not limited to, arranged along the first direction.

[0020] The movement process of the absorption compensation film 170 is as follows: when each laser shock position 310 is completed, the absorption compensation film 170 moves a set distance along the first direction and stops moving after moving the set distance. The set distance is greater than the length of the overlapping portion between two adjacent positions to be laser shocked along the first direction. For example, the set distance can be more than 1.5 times the length of the overlapping portion along the first direction. Preferably, the set distance is greater than the diameter of the position to be laser shocked, so that the portion of the absorption compensation film 170 corresponding to the position to be compensated 320 can maintain a good levelness, thereby improving the compensation effect of the absorption compensation film 170.

[0021] In some embodiments of the present application, the laser impact device includes a laser impact head 400, which is arranged above the absorption compensation film 170, and the laser impact head 400 is formed with a laser channel 410 and a liquid guide channel 420. The laser emission head is arranged toward the laser channel 410, and the laser beam emitted by the laser emission head passes through the laser channel 410, passes through the laser impact head 400, and is emitted toward the current position to be laser impacted. The top of the liquid guide channel 420 is connected to a liquid delivery device, and a restraining liquid is sprayed toward the current position to be laser impacted through the liquid guide channel 420. The restraining liquid can be, but is not limited to, water, etc. Under the action of the restraining liquid discharged by the liquid guide channel 420, the absorption compensation film 170 is tightly attached to the current position to be impacted on the first absorption layer 220, so as to ensure that the absorption compensation film 170 is tightly attached to the first absorption layer 220 at least in the portion corresponding to the current position to be laser impacted, so as to ensure the effect of the absorption layer.

[0022] The laser impact head 400 may be installed on a robotic arm to meet the multi-dimensional movement of the laser impact head 400 .

[0023] In some embodiments of the present application, the conveying mechanism is movably arranged along the second direction, and the first direction is perpendicular to the second direction, so that the absorption compensation film 170 can move two-dimensionally along the horizontal direction to meet the use requirements of different laser impact positions 310.

[0024] The first direction may be parallel to the length direction of the carrying platform 110 , and the second direction may be parallel to the width direction of the carrying platform 110 .

[0025] In some embodiments of the present application, the support platform 110 can be raised and lowered, which can not only meet the laser impact use requirements of the processing equipment for metal substrates 200 of different heights, but also adjust the bonding force between the absorption compensation film 170 and the first absorption layer 220.

[0026] The support platform 110 can be lifted and moved by a driving mechanism such as an electric push rod or a hydraulic cylinder.

[0027] In some embodiments of the present application, the conveying mechanism includes a first reel 120 and a second reel 130, and the first reel 120 and the second reel 130 are both mounted on the frame through a first reel 120 bracket, and the first reel 120 and the second reel 130 can be rotatably arranged. The first reel 120 and the second reel 130 are respectively located on both sides of the carrier 110, and the two ends of the absorption compensation film 170 are respectively wound on the first reel 120 and the second reel 130, and the first reel 120 releases the absorption compensation film 170 by rotation, and the second reel 130 rewinds the compensation film by rotation. The above-mentioned conveying mechanism realizes movement along the first direction by rewinding and unwinding the absorption compensation film 170, ensuring that the moving action can be faster, and realizing efficient operation of laser shock.

[0028] In some embodiments of the present application, the conveying mechanism further includes a first guide roller 140 assembly and a second guide roller 150 assembly, the first guide roller 140 assembly is located between the first reel 120 and the carrier 110, the second guide roller 150 assembly is located between the second reel 130 and the carrier 110, the first guide roller 140 assembly includes two first guide rollers 140 arranged opposite to each other up and down, the second guide roller 150 assembly includes two second guide rollers 150 arranged opposite to each other up and down, the frame is provided with a second reel 130 bracket and a third reel bracket, the two first guide rollers 140 are mounted on the second reel 130 bracket, the two second guide rollers 150 are mounted on the third reel bracket, and the absorption compensation film 170 passes through between the two first guide rollers 140 and between the two second guide rollers 150 in sequence.

The third reel support is provided with a vertically arranged guide groove and a linear drive, the roller neck of the second guide roller 150 located at the top is inserted into the guide groove, and the linear drive cooperates with the roller neck drive to drive the second guide roller 150 to move up and down. When the absorption compensation film 170 needs to be moved to cover the position to be compensated 320, the second guide roller 150 located at the top moves up to separate from the second guide roller 150 located at the bottom; after the absorption compensation film 170 moves a set distance, the second guide roller 150 located at the top moves down to clamp the absorption compensation film 170 together with the second guide roller 150 located at the bottom.

The adjusting roller 160 is suspended on the top surface of the absorption compensation film 170, so that the first reel 120 and the second reel 130 do not need to be stopped for processing during the laser shock operation. Specifically: the adjusting roller 160 can use its own weight to press down the absorption compensation film 170, so that the absorption compensation film 170 forms a surplus section between the first guide roller 140 assembly and the first reel 120 and between the second guide roller 150 assembly and the second reel 130.
