In order to facilitate the adjustment of the laser focusing position of the laser module, a fixed table 2 for placing a workpiece is fixedly connected to the upper side of the fixed plate 1. A gas adsorption mechanism 3 is provided on the left side of the fixed table 2. A support frame 4 fixedly connected to the fixed plate 1 is provided on the rear side of the fixed table 2. Two detection rods 5 for detecting the resistance of the workpiece are provided in the middle of the front side of the support frame 4. The detection rods 5 are used to detect the resistance value and other data of the workpiece. A laser emitter 6 is fixedly connected to the front side of the upper part of the support frame 4. A height-adjustable placement frame 7 is provided on the lower side of the laser emitter 6. A replaceable light-transmitting mirror 8 is provided in the middle of the placement frame 7. A protective mechanism 9 is provided on the lower side of the light-transmitting mirror 8. The protective mechanism 9 is electrically connected to the detection rod 5.

[0029] When in use, the workpiece that needs to be laser-trimmed can be placed on the fixed table 2, and the workpiece can be fixed by the fixed table 2. A placement groove is provided on the upper side of the fixed table 2 for placing and positioning the workpiece. After the resistance value of a specific position of the workpiece is detected by the detection rod 5, laser resistance trimming can be performed. When laser resistance trimming is performed, the laser emitter 6 can emit a laser. After the laser is focused to a suitable focal length by the light-transmitting mirror 8, the workpiece can be cut by the high energy of the laser to adjust the resistance value of the workpiece. In this process, by adjusting the height of the placement rack 7, the height of the laser focus can be adjusted, which can improve the accuracy of laser resistance trimming. In the process of laser resistance trimming, the gas adsorption mechanism 3 can adsorb the odor generated by the melted material in the process of laser resistance trimming, thereby reducing the risk of harmful gases being inhaled by the staff. In the process of laser resistance trimming, the detection rod 5 detects the resistance value of the workpiece in real time. When the resistance value of the workpiece meets the requirements, the detection rod 5 sends an electrical signal to the protection mechanism 9, so that the protection mechanism 9 starts to block the laser, thereby increasing the consistency of the output workpiece.

[0030] Further, by Figure 1-Figure 5 As shown, in order to facilitate the operation of the staff, a liftable adjustment plate 10 is provided on the upper side of the laser emitter 6, and an extension plate 11 is fixedly connected to the left and right sides of the adjustment plate 10, and a lifting sliding groove 12 is provided on the left and right sides of the laser emitter 6, and each extension plate 11 is slidably connected to the corresponding lifting sliding groove 12, and the lower side of each extension plate 11 is fixedly connected to the placement frame 7;

[0031] Further, by Figure 1-Figure 5 As shown, in order to make the height adjustment of the placement rack 7 more accurate, a first motor 13 is fixedly connected to the upper side of the laser emitter 6, and a first bevel gear 14 is fixedly connected to the output end of the first motor 13, and a second bevel gear 15 rotatably connected to the laser emitter 6 is meshed on one side of the first bevel gear 14, and a worm 16 is fixedly connected to the side of the second bevel gear 15 away from the first bevel gear 14, and a worm gear 17 rotatably connected to the laser emitter 6 is meshed on one side of the worm gear 16, and a first threaded rod 18 is coaxially fixedly connected to the upper side of the worm gear 17, and the middle part of the first threaded rod 18 is threadedly connected to the adjustment plate 10; the laser emitter 6 is a prior art, such as an Nd:YAG laser, which will not be described in detail here, and the light-transmitting mirror 8 is threadedly connected to the middle part of the placement rack 7, so as to facilitate the replacement and maintenance of the light-transmitting mirror 8;

[0032] During use, when the extension plate 11 slides up and down along the lifting sliding groove 12, it will drive the placement rack 7 to slide up and down. When adjustment is needed, the first motor 13 can be started. The first motor 13 drives the worm 16 to rotate through the first bevel gear 14 and the second bevel gear 15. The worm 16 drives the worm wheel 17 to rotate, thereby driving the first threaded rod 18 to rotate. Since the adjustment plate 10 is threadedly connected to the first threaded rod 18, it will drive the placement rack 7 to rise and fall through the extension plate 11, and then adjust the height of the light transmitting mirror 8 relative to the laser emitter 6.

[0033] Further, by Figure 1-Figure 5 As shown, in order to achieve the purpose of quickly blocking the laser, the protection mechanism 9 includes a lower plate 19 fixedly connected to the extension plate 11 and an upper plate 20 fixedly connected to the placement frame 7, a plurality of movable plates 21 are arranged between the upper plate 20 and the lower plate 19, a curved plate 22 is fixedly connected to the lower side of each extension plate 11, and the lower side of each curved plate 22 is fixedly connected to the lower plate 19, and a circular hole 23 coaxially arranged with the light-transmitting mirror 8 is opened in the middle of the upper plate 20 and the lower plate 19;

[0034] Further, by Figure 1-Figure 5 As shown, a circular block 24 is fixedly connected to the upper side of each movable plate 21, a circular groove 25 is provided in the middle of the upper plate 20 corresponding to the position of each circular block 24, and each circular block 24 is slidably connected to the corresponding circular groove 25, a square block 26 is fixedly connected to the lower side of each movable plate 21, a square hole 27 is provided in the middle of each lower plate 19 corresponding to the position of each square block 26, and each square block 26 is slidably connected to the corresponding square hole 27;

[0035] When in use, the laser emitted by the laser emitter 6 will adjust the resistance of the workpiece through the circular hole 23. When the laser needs to be blocked by the protective mechanism 9, the upper plate 20 can be rotated. At this time, the circular block 24 is driven to move through the circular groove 25. With the cooperation of the square hole 27 and the square block 26, each moving block moves relative to the lower plate 19, and the circular groove 25 is quickly blocked, so that the laser emitted by the laser emitter 6 cannot pass through, and the laser resistance adjustment can be quickly stopped.

[0036] Further, by Figure 1-Figure 5 As shown, in order to facilitate the operation of the staff, a telescopic block 28 is fixedly connected to the rear side of the upper plate 20, and an electric telescopic rod 29 is fixedly connected to the rear side of the telescopic block 28. The electric telescopic rod 29 is a prior art and will not be described in detail here. A sliding block 30 is rotatably connected to the rear end of the electric telescopic rod 29, and the rear side of the sliding block 30 is slidably connected to the support frame 4;

[0037] When in use, the telescopic block 28 can be driven to move by the extension and retraction of the electric telescopic rod 29, thereby causing the upper plate 20 to rotate relative to the lower plate 19, thereby driving the moving plate 21 to move.

[0038] Further, by Figure 1-Figure 5 As shown, in order to reduce the harm of gas to the body of the staff, the gas adsorption mechanism 3 includes an air inlet pipe 31 and an air outlet pipe 32, the air outlet pipe 32 and the side of the air inlet pipe 31 close to the placement rack 7 are respectively located at the front and rear sides of the placement rack 7, the end of the air inlet pipe 31 away from the placement rack 7 is connected to a filter box 33, the side of the air outlet pipe 32 away from the placement rack 7 is connected to a fan 34, the bottom of the filter box 33 is connected to the air inlet of the fan 34, and the fan 34 and the filter box 33 are fixedly connected to the placement rack 7;

[0039] When in use, after starting the fan 34, negative pressure can be generated inside the filter box 33, and then air is sucked through the air inlet pipe 31, and the gas generated during laser resistance adjustment is sucked into the filter box 33 through the air inlet pipe 31. The filter box 33 is filled with gas adsorption materials, such as silica gel, alumina, molecular sieves, natural clay, activated carbon, etc. Furthermore, the gas adsorption materials in the filter box 33 can be updated and replaced.

[0040] Further, by Figure 1-Figure 5 As shown, in order to facilitate the fixation of the workpiece, a bellows 35 is connected to the side of the air inlet pipe 31 and the air outlet pipe 32 close to the placement rack 7, and each bellows 35 is connected to an adsorption rack 36 on the side close to the placement rack 7. Each adsorption rack 36 can slide forward and backward along the placement rack 7. A rotating rack 37 is rotatably connected to the upper side of the placement rack 7. Two arc grooves 38 are provided on the upper side of the rotating rack 37. A power block 39 is fixedly connected to the lower side of each adsorption rack 36, and each power block 39 is slidably connected to the corresponding arc groove 38.

[0041] When in use, through the adsorption rack 36 connected to the placement rack 7 for forward and backward sliding, the two adsorption racks 36 can be moved away from each other when placing the workpiece, and then the two adsorption racks 36 can be moved close to each other after the workpiece is placed, so as to facilitate the positioning and installation of the workpiece. By rotating the rotating rack 37, the corresponding power block 39 can be driven to move through the two arc grooves 38, thereby driving the adsorption rack 36 to move. When the adsorption rack 36 moves relative to the air inlet pipe 31 and the air outlet pipe 32, under the action of the bellows 35, the adsorption rack 36 can always remain connected with the air inlet pipe 31 and the air outlet pipe 32.

[0042] Further, by Figure 1-Figure 5As shown, in order to enable the device to operate automatically, a gear ring 40 is fixedly connected to the bottom of the rotating frame 37, and a power gear 41 rotatably connected to the placement frame 7 is meshed inside the gear ring 40, and a second motor 42 is fixedly connected inside the placement frame 7, and the output shaft of the second motor 42 is fixedly connected to the power gear 41;

[0043] It should be noted that the second motor 42 is in communication connection with the electric telescopic rod 29;

[0044] When in use, when the electric telescopic rod 29 drives the protection mechanism 9 to operate so that the laser can pass through the circular hole 23 to perform laser resistance adjustment, the second motor 42 will also start, and the gear ring 40 will be driven to rotate through the power gear 41, and then the gear ring 40 will drive the rotating frame 37 to rotate, so that the arc groove 38 opened on the upper side of the rotating frame 37 can drive the power block 39 to move;

[0045] Further, by Figure 1-Figure 5 As shown, in order to facilitate loading and unloading of workpieces, a circular table 43 is fixedly connected to the upper side of the fixed plate 1, a square sleeve 44 is fixedly connected to the upper side of the circular table 43, a square groove 45 is provided at the bottom of the fixed table 2, the square sleeve 44 can slide up and down along the square groove 45, a threaded sleeve 46 is fixedly connected inside the square groove 45, a third motor 47 is fixedly connected inside the circular table 43, a second threaded rod 48 is fixedly connected to the output shaft of the third motor 47, and the second threaded rod 48 is threadedly connected to the threaded sleeve 46;

[0046] It should be noted that the first motor 13, the second motor 42 and the third motor 47 are all servo motors, which are all prior art and will not be described in detail here;

[0047] When in use, after starting the third motor 47, the third motor 47 drives the second threaded rod 48 to rotate, thereby driving the threaded sleeve 46 to rise and fall under the action of the threaded connection between the threaded sleeve 46 and the threaded rod. During this process, the square sleeve 44 and the square groove 45 cooperate with each other to limit the rotation of the fixed table 2, thereby completing the lifting and lowering of the fixed table 2. After the fixed table 2 descends, the workpiece is away from the detection rod 5, which is convenient for loading and unloading the workpiece.

[0048] When the present invention is used, first, the workpiece that needs to be laser-trimmed can be placed on the fixed table 2, and the workpiece can be fixed by the fixed table 2. After the resistance value of a specific position of the workpiece is detected by the detection rod 5, the laser resistance can be adjusted. When the laser resistance is adjusted, the laser emitter 6 can emit a laser. After the laser is focused to a suitable focal length by the light-transmitting mirror 8, the workpiece can be cut by the high energy of the laser to adjust the resistance value of the workpiece. In this process, by adjusting the height of the placement frame 7, the height of the laser focus can be adjusted, which can improve the accuracy of the laser resistance adjustment. When the height of the placement frame 7 needs to be adjusted, the first motor 13 can be started. The first motor 13 drives the worm 16 to rotate through the first bevel gear 14 and the second bevel gear 15. The worm 16 drives the worm wheel 17 to rotate, thereby driving the first threaded rod 18 to rotate. Since the adjustment plate 10 is threadedly connected to the first threaded rod 18, it will pass through the extension plate 1 1 drives the placement rack 7 to rise and fall, and then adjusts the height of the light-transmitting mirror 8 relative to the laser emitter 6. During the laser resistance adjustment process, the gas adsorption mechanism 3 can adsorb the odor generated by the melted material during the laser resistance adjustment process, thereby reducing the risk of harmful gases being inhaled by the staff. After starting the fan 34, a negative pressure can be generated inside the filter box 33, and then air is sucked through the air inlet pipe 31 to suck the gas generated during the laser resistance adjustment into the filter box 33 through the air inlet pipe 31. The filter box 33 is filled with gas adsorption materials, such as silica gel, alumina, molecular sieve, natural clay, activated carbon, etc. Further, the gas adsorption material in the filter box 33 can be updated and replaced. During the laser resistance adjustment process, the detection rod 5 detects the resistance value of the workpiece in real time. When the resistance value of the workpiece meets the requirements, the detection rod 5 sends an electrical signal to the protection mechanism 9, so that the protection mechanism 9 starts to block the laser, thereby increasing the consistency of the output workpiece.

[0049] The present invention has a novel structure, ingenious conception, and simple and convenient operation. Through this design, the purpose of facilitating the adjustment of the laser focusing position of the laser module is effectively achieved, which is convenient for the operation of the staff, makes the height adjustment of the placement rack 7 more precise, achieves the purpose of being able to quickly block the laser, facilitates the operation of the staff, reduces the harm of the gas to the body of the staff, facilitates the fixation of the workpiece, enables the automatic operation of the device, and facilitates the loading and unloading of the workpiece.
