[0036] The invention provides an automated laser de-coating production line.

[0037] In the embodiment of the present invention, Figures 1 to 4 As shown, the laser decoating automated assembly line is used to remove the coating of a watch case 10, and the laser decoating automated assembly line includes a conveyor belt 100, and equipment one 200, equipment two 300 and equipment three 400 arranged in sequence along the conveying direction of the conveyor belt 100, the equipment one 200 includes a first laser system 210, the equipment two 300 includes a second laser system 310, one of the first laser system 210 and the second laser system 310 is used to remove the coating on the front side of the case 10, and the other is used to remove the coating on the back side of the case 10; the equipment three 400 includes a third laser system 410, and the third laser system 410 is used to remove the coating on the surface groove of the case 10.

[0038] Specifically, in order to facilitate the dispensing process on the surface of the watch case 10, it is necessary to perform a decoating operation on the watch case 10. The laser decoating automated assembly line is used to remove the coating of the watch case 10, and the decoating location can be the front, back and table groove of the watch case 10. When it is necessary to remove the coating on the front, back and table groove of the watch case 10, the device 1 200, the device 2 300 and the device 3 400 can be arranged in sequence to remove the coating on the front, back and table groove of the watch case 10 respectively. It should be noted that when only one or two of the front, back and table groove of the watch case 10 need to be removed, the corresponding device 1 200, the device 2 300 and the device 3 400 can be appropriately selected; the order of the device 1 200, the device 2 300 and the device 3 400 can also be changed according to actual conditions.

[0039] The conveyor belt 100 has a feed end and a discharge end. The feed end is used for discharging materials, and the discharging method can be manual discharging or discharging by a discharging device; the discharge end is used for discharging materials, and a material receiving assembly can be installed at the discharge end to collect the watch cases 10 that have been de-coated. It can be understood that the watch cases 10 can be placed directly on the conveyor belt 100, or the watch cases 10 can be placed on a material tray 20, and the material tray 20 moves on the conveyor belt 100 to convey the watch cases 10. The material tray 20 can carry only one watch case 10, or it can carry multiple watch cases 10.

[0040] The first device 200, the second device 300 and the third device 400 can be installed on one side between the feeding end and the discharging end of the conveyor belt 100. The first device 200, the second device 300 and the third device 400 are arranged in sequence. The watch case 10 to be processed is transported from the feeding end to the first device 200. The first device 200, the second device 300 and the third device 400 remove the coating on the watch case 10 in sequence and finally put it back on the conveyor belt 100. Figures 3 to 4 As shown, a CCD visual positioning component 110 can be installed on the conveyor belt 100, and the CCD visual positioning component 110 is used to take a picture of the watch case 10 on the conveyor belt 100, so as to obtain the position information of the watch case 10 and the orientation information of the watch case 10, which is convenient for the subsequent grasping of the watch case 10 and the adjustment of the position of the watch case 10. When the watch case 10 is conveyed by the material tray 20, a material blocking cylinder can be installed on the conveyor belt 100, and the material blocking cylinder is used to block or release the material tray 20 on the conveyor belt 100, so as to facilitate the CCD visual positioning component 110 to take a picture and position the watch case 10.

[0041] The device 1 200 includes a first laser system 210, and the device 2 300 includes a second laser system 310. One of the first laser system 210 and the second laser system 310 is used to remove the coating on the front side of the watch case 10, and the other is used to remove the coating on the back side of the watch case 10. That is to say, when the first laser system 210 is used to remove the coating on the front side of the watch case 10, the second laser system 310 is used to remove the coating on the back side of the watch case 10; when the first laser system 210 is used to remove the coating on the back side of the watch case 10, the second laser system 310 is used to remove the coating on the front side of the watch case 10, thereby removing the coating on both the front and back sides of the watch case 10. It should be noted that the specific positions where the first laser system 210 and the second laser system 310 remove the coating on both the front and back sides of the watch case 10 can be set according to the actual situation of the first laser system 210 and the second laser system 310, and are not limited here.

[0042] The third device 400 includes a third laser system 410, which is used to remove the coating of the surface groove of the watch case 10, wherein the number of surface grooves that need to remove the coating can be one or more; the specific position in the surface groove where the coating needs to be removed can also be set for the third laser system 410 according to actual conditions, which is not limited here. The types of the first laser generator 211, the second laser generator 311 and the third laser generator 411 can be the same or different, and can be selected according to actual conditions. Among them, the types of laser generators include ultraviolet lasers, infrared lasers, fiber lasers or carbon dioxide lasers.

[0043] The conveyor belt 100 is used to convey the watch case 10 or the material tray 20 to be de-coated, the device 1 200 and the device 200 perform de-coating operations on the front and back sides of the watch case 10, and the device 3 400 performs de-coating operations on the surface groove of the watch case 10. It can be understood that the laser de-coating automatic assembly line can operate on the front and back sides and the surface groove of the same watch case 10, or can perform de-coating operations on different watch cases 10 respectively. The following embodiments are specifically described by taking the removal of coatings on the front and back sides and the surface groove of the same watch case 10 as an example.

[0044] The technical solution of the present invention can perform laser de-coating operations on the front and back sides and the watch groove of the watch case 10 by sequentially arranging the device 1 200, the device 2 300 and the device 3 400 in the conveying direction of the conveyor belt 100, thereby completing the steps of removing the coating of the watch case 10 at the required position, with a high degree of automation, solving the problem of low efficiency and long time consumption of manual removal of the coating of the watch case 10, improving the work efficiency of the coating removal of the watch case 10, greatly saving manpower, reducing the labor cost of the enterprise, and facilitating the manufacturer to carry out large-scale processing and production of the watch case 10. At the same time, the laser de-coating automated assembly line uses laser to remove the coating of the watch case 10, which greatly improves the product yield and overcomes the problem of low yield of manual de-coating.

[0045] There are many ways to fix the watch case 10 on the first fixture assembly 220, such as Figures 3 to 7 As shown, in one embodiment, the device 200 has a first machine 201, on which the first laser system 210 is installed, the first laser system 210 includes a first laser generator 211, and a first fixture assembly 220 is installed below the first laser generator 211; the first fixture assembly 220 includes a base plate 221, on which a placement plate 222 and a pusher assembly 225 are installed, the placement plate 222 includes a plate body 223 and an extension portion 224 provided on the plate body 223, the plate body 223 is used to support the watch case 10, the extension portion 224 and the pusher assembly 225 are arranged opposite to each other, and are used to clamp the watch case 10 between the extension portion 224 and the pusher assembly 225.

[0046] Specifically, a first fixture assembly 220 is installed below the first laser generator 211. The first fixture assembly 220 is used to clamp the watch case 10. The laser beam generated by the first laser generator 211 can be irradiated on the watch case 10 clamped on the first fixture assembly 220 to perform a coating removal operation on the watch case 10. It can be understood that the number of the first laser generators 211 can be multiple, and multiple first laser generators 211 respectively perform coating removal operations on multiple watch cases 10, thereby further improving the working efficiency of the assembly line. In addition, multiple first laser generators 211 can operate independently, and the operation is flexible.

[0047] When the watch case 10 is placed on the storage plate 222, the watch case 10 is clamped between the pusher assembly 225 and the extension portion 224 under the push of the pusher assembly 225. In order to adjust the relative horizontal position of the first fixture assembly 220, a plurality of leveling screw holes can be provided on the bottom plate 221, and leveling screws are inserted into the leveling screw holes. The bottom surface of the screw rod of the leveling screw is stopped at the first machine 201. By rotating the leveling screws, the leveling screws rotate in the leveling screw holes of the bottom plate 221, so that the bottom plate 221 is lifted up or dropped down, thereby adjusting the relative horizontal position of the first fixture assembly 220.

[0048] Furthermore, the pusher assembly 225 may have various structures, such as Figure 7 As shown, in one embodiment, the pusher assembly 225 includes a fixing member 226, an elastic member (not shown) and a connecting member 227, the fixing member 226 is fixed to the base plate 221, the elastic member is respectively connected to the fixing member 226 and the connecting member 227, and the connecting member 227 is used to cooperate with the extension portion 224 to clamp the watch case 10.

[0049] When the watch case 10 is not placed on the storage plate 222, the distance between the extension 224 and the connecting member 227 is less than the width or length of the watch case 10. When the watch case 10 is placed flat on the storage plate 222, one end of the watch case 10 abuts against the extension 224, and the other end exerts a force on the connecting member 227. At this time, the elastic member is compressed, and the elastic member acts on the connecting member 227, and the connecting member 227 exerts a reaction force on the watch case 10, thereby clamping the watch case 10 between the connecting member 227 and the extension 224. A linear guide can also be installed between the fixing member 226 and the connecting member 227 to limit the moving path of the connecting member 227, thereby preventing the watch case 10 from falling off the first fixture assembly 220. It can be understood that the elastic member can include a spring.

[0050] In order to stably clamp the watch case 10 on the first fixture assembly 220, one end of the connecting member 227 facing the extension portion 224 is recessed to form an arc-shaped abutting end, and the side of the abutting end facing the extension portion 224 is an abutting surface in contact with the watch case 10, and the distance between the abutting surface and the extension portion 224 gradually increases from top to bottom, that is, the abutting surface is an inclined surface. When the watch case 10 is clamped between the connecting member 227 and the extension portion 224, the connecting member 227 pushes the watch case 10 to generate a forward and downward force, so as to stably clamp the watch case 10 on the first fixture.

[0051] In order to further improve the working efficiency of the pipeline, Figures 5 to 6 As shown, in one embodiment, a turntable assembly 230 is installed on the first machine 201, and the turntable assembly 230 includes a turntable 231, and a plurality of the first fixture assemblies 220 are installed on the turntable 231. The plurality of the first fixture assemblies 220 can rotate alternately to the bottom of the first laser generator 211.

[0052] By rotating the plurality of first fixture assemblies 220 alternately to the bottom of the first laser generator 211, the first laser generator 211 can remove the coating of the watch case 10 on the plurality of first fixture assemblies 220 respectively, thereby shortening the waiting time of the first laser generator 211 and improving the working efficiency of the assembly line. It should be noted that when one first fixture assembly 220 is performing the laser decoating operation, other first fixture assemblies 220 can perform the loading or unloading operation to further improve the working efficiency of the assembly line.

[0053] Specifically, Figures 5 to 6 As shown, in one embodiment, the turntable assembly 230 also includes a rotating cylinder 232, and the rotating cylinder 232 is installed at the bottom of the turntable 231; the rotating cylinder 232 is provided with a turntable 231, and a plurality of the jig assemblies are installed on the turntable 231; the first machine 201 is installed with a jig lifting assembly 240 and a jig pushing assembly 250, when the jig assembly is transferred to the laser working area, the jig lifting assembly 240 and the jig pushing assembly 250 are arranged relative to the first laser generator 211, the jig lifting assembly 240 is used to lift the first jig assembly 220 of the jig assembly, and the jig pushing assembly 250 is used to pull and push the connecting member 227 to increase the distance between the connecting member 227 and the extending portion 224, so that the watch case 10 is clamped more firmly by the connecting member 227 and the extending portion 224.

[0054] The turntable 231 is rotated by the rotating cylinder 232 , so that the plurality of first fixture assemblies 220 on the turntable 231 are respectively rotated to the working area below the first laser generator 211 . The jig lifting assembly 240 and the jig pushing assembly 250 are arranged opposite to the first laser generator 211, that is, the jig lifting assembly 240 and the jig pushing assembly 250 are not below the first laser generator 211. When the first jig assembly 220 in the working area is laser de-coating, after another first jig assembly 220 is lifted by the jig lifting assembly 240, the jig pushing assembly 250 pulls the connecting piece 227 to increase the distance between the connecting piece 227 and the extending portion 224 to remove the processed watch case 10 or place the watch case 10 to be processed. In this way, the first jig assembly 220 in the working area is independent of the other first jig assemblies 220, and the vibration generated by the other first jig assemblies 220 during the loading and unloading process will not interfere with the first jig assembly 220 in the working area, and will not affect the laser de-coating effect of the first jig assembly 220 in the working area.

[0055] like Figure 6 As shown, there are various structures of the jig pushing assembly 250. In one embodiment, the jig pushing assembly 250 includes a support platform, on which a stretching cylinder is installed. The stretching cylinder includes a stretching cylinder body and a plug rod passing through one end of the stretching cylinder body, and a push block is installed on the plug rod. At the same time, a connecting block 228 is protruding from the connecting member 227. When the first jig assembly 220 is lifted by the jig lifting assembly 240, the connecting block 228 on the connecting member 227 abuts against a side of the push block connected to the plug rod, and moves toward the stretching cylinder body through the horizontal direction of the plug rod, thereby driving the connecting block 228 to move toward the stretching cylinder body, thereby increasing the distance between the connecting member 227 and the extension portion 224.

[0056] Furthermore, if Figures 3 to 5 As shown, in one embodiment, the device 200 also includes a loading module, which includes a mobile unit 260 and a loading clamp assembly (not shown) installed on the mobile unit 260, and the loading clamp assembly is used to clamp the watch case 10 to be processed on the conveyor belt 100; the mobile unit 260 includes a Y-axis servo mobile unit, an X-axis servo mobile unit, a Z-axis servo mobile unit and a servo rotation unit connected in sequence, wherein the loading clamp assembly is installed on the servo rotation unit.

[0057] The Y-axis servo mobile unit is installed with an X-axis servo mobile unit, the X-axis servo mobile unit is installed with a Z-axis servo mobile unit, and the Z-axis servo mobile unit is installed with a servo rotating unit, and the servo rotating unit is installed with a loading jaw assembly. In this way, the loading jaw assembly can be moved in the X-axis, Y-axis and Z-axis directions through the mobile unit, and under the action of the servo rotating unit, the angle of the loading jaw assembly can be rotated, thereby adjusting the angle of the case 10 on the loading jaw assembly.

[0058] When the CCD visual positioning component 110 takes a picture of the watch case 10 on the conveyor belt 100 and obtains the position information and orientation information of the watch case 10, the loading clamp assembly moves and grabs the watch case 10 through the moving unit 260. In the process of moving the watch case 10 into the device 1 200, the angle position of the watch case 10 can be adjusted to facilitate the subsequent process. It can be understood that the loading clamp assembly can include a loading clamp hand and a loading clamp cylinder, the loading clamp hand is used to clamp or release the watch case 10, and the loading clamp cylinder is used to control the clamping or releasing action of the loading clamp hand.

[0059] In order to turn over the watch case 10, the front or back of the watch case 10 faces upward, such as Figure 4 , Figure 8 As shown, in one embodiment, the device 1 200 and / or the device 2 300 includes a rotating assembly 270, the rotating assembly 270 includes a rotating part 271 and a storage table 278, the rotating part 271 includes a base 272 and a first gripper assembly 273 installed on the base 272, the first gripper assembly 273 includes a first gripper hand 274, a first gripper cylinder 275 and a gripper hand rotating cylinder 276, the first gripper hand 274 is connected to the gripper hand rotating cylinder 276 through the first gripper cylinder 275, and the gripper hand rotating cylinder 276 is installed on the base 272; the storage table 278 is installed below the first gripper hand 274 through a lifting cylinder 279, and a pushing cylinder 280 is installed on the storage table 278, and the pushing cylinder 280 is arranged opposite to the first gripper hand 274.

[0060] The watch case 10 is moved to the storage table 278, and the first gripper hand 274 is in an open state. The pushing cylinder 280 on the storage table 278 pushes the watch case 10 into the first gripper hand 274, and the first gripper cylinder 275 controls the first gripper hand 274 to contract and clamp the watch case 10. Then the pushing cylinder 280 is retracted, and the lifting cylinder 279 under the storage table 278 descends, and the storage table 278 also descends with the lifting cylinder 279. Then the rear gripper hand rotating cylinder 276 drives the first gripper hand 274 to rotate 180 degrees. At this time, the watch case 10 is flipped over, and the other side of the watch case 10 faces upward. The lifting cylinder 279 rises and abuts against the first gripper hand 274. The first gripper cylinder 275 controls the first gripper hand 274 to open, completing the flipping operation of the watch case 10. The number of the rotating components 270 can be two, one for flipping the watch case 10 obtained by the loading module, and the other for flipping the watch case 10 from which one side of the coating has been removed.

[0061] It is understandable that the push cylinder 280 may include a cylinder body and a push rod passing through one end of the cylinder body, and the end of the push rod may be provided with a rubber to prevent the push rod from rigidly contacting the watch case 10, thereby protecting the watch case 10. The watch case 10 may be moved to the storage table 278 by the loading jaw assembly, or by other moving assemblies.

[0062] like Figures 4 to 5 , Fig. 9 As shown, the device 200 may also include a material moving component 290, which includes a material moving bracket 291, on which a material moving cylinder 292 is mounted, and on which a material moving claw component 293 is provided for driving the material moving claw component 293 to move, and the material moving claw component 293 is used to grab or release the watch case 10, and the specific structure of the material moving claw component 293 may refer to the loading claw component. It is understandable that the number of material moving clamping assemblies 293 on the material moving bracket 291 can be two sets, and the loading and unloading operations can be performed simultaneously. One set of material moving clamping assemblies 293 can move the watch case 10 from the storage table 278 to the first fixture assembly 220, that is, the loading of the first fixture assembly 220; the other set of material moving clamping assemblies 293 can move the watch case 10 from the first fixture assembly 220 to another storage table 278 or the material waiting assembly, that is, the unloading of the first fixture assembly 220. The specific structure of the material waiting assembly is described in the following content. The number of the material moving assembly 290 can be one or more, and can be installed according to the specific situation in the device 200.

[0063] The material moving cylinder 292 and the material moving jaw assembly 293 on the material moving bracket 291 can be two sets to form two material moving lines. Each material moving line can correspond to a first laser generator 211 and a first fixture assembly 220. The two material moving lines can process simultaneously without affecting each other, thereby improving the working efficiency of the assembly line.

[0064] The first machine 201 may also be equipped with a barcode scanning gun assembly (not shown) for reading the QR code on the product to obtain the product type information. To facilitate barcode scanning, the barcode scanning gun assembly may be installed on the X-axis servo moving unit to scan the watch case 10 on the storage table 278 or the watch case 10 grasped by the material transfer clamp assembly 293.

[0065] The structure of the device 2 300 can be various, such as Figures 3 to 4 , Fig.10 As shown, in one embodiment, the device 2 300 has a second machine 301, and the second laser system 310 is installed on the second machine 301. The second laser system 310 includes a second laser generator 311, and a second fixture assembly (not shown) is installed below the second laser generator 311; a material waiting assembly is also installed on the second machine 301, and the material waiting assembly is used to place the watch case 10.

[0066] Since one of the device 1 200 and the device 2 300 removes the front side of the watch case 10 and the other removes the back side of the watch case 10, the specific structure of the second fixture assembly can refer to the structural setting of the first fixture assembly 220, and has the beneficial effects brought by the technical solutions of the corresponding embodiments, which will not be described one by one here. Similarly, the specific structure of the device 2 300 can refer to the embodiment of the device 1 200, and obtain the beneficial effects brought by the technical solutions of the corresponding embodiments. The difference is that the device 2 300 can be without a loading module, and does not need to clamp the watch case 10 from the conveyor belt 100; if the watch case 10 completes the flipping operation after the coating is removed by the device 1 200, the device 2 300 can also not install the rotating assembly 270.

[0067] The second machine 301 is also equipped with a waiting assembly (not shown), which is used to place the watch case 10. The number of the waiting assembly can be two, and the two waiting assemblies can be located at both ends of the fixture assembly, so as to facilitate loading and unloading operations on the second fixture assembly. The waiting assembly can include a support seat and a pre-positioning block installed on the support seat, and the pre-positioning block can be recessed inward to form a receiving groove, and the receiving groove is used to receive the watch case 10. When the second device 300 is provided with two material transfer lines, the number of the pre-positioning blocks can be two.

[0068] The structure of the device 3 400 is various, such as Figures 3 to 4 , Figures 11 to 12As shown, in one embodiment, the device three 400 has a third machine 401, and the third laser system 410 is installed on the third machine 401. The third laser system 410 includes a third laser generator 411, and a third fixture assembly 420 is installed below the third laser generator 411. The third laser generator 411 is used to generate a laser beam; the third machine 401 is also equipped with an angle tilting lifting cylinder 430, and the angle tilting lifting cylinder 430 is used to adjust the angle between the third fixture assembly 420 and the laser beam.

[0069] Specifically, the specific structure of the third fixture assembly 420 can refer to the structural setting of the first fixture assembly 220, and has the beneficial effects brought by the technical solutions of the corresponding embodiments, which will not be described one by one here. An angle tilting jacking cylinder 430 is installed below the third laser generator 411, and the angle tilting jacking cylinder 430 is used to tilt and lift the third fixture assembly 420, so that the surface groove of the watch case 10 fixed on the third fixture assembly 420 is exposed, so that the inner wall of the surface groove is facing the laser beam emission position, and the third laser system 410 completes the coating removal operation of the surface groove.

[0070] The third machine 401 may also be equipped with a material receiving assembly 450 (not shown), which is used to temporarily place the watch case 10 and serves as a transfer. When the device 3 400 only performs a coating removal operation on the surface groove of a watch case 10, and the device 1 200 and the device 2 300 both include two material transfer lines, in order to match the unit hourly production capacity requirements of the assembly line, the device 3 400 may have only one material transfer line, so the material receiving assembly 450 may include a material receiving seat and a material receiving block, and the material receiving block is installed on the material receiving seat through a moving cylinder, and the moving cylinder can drive the material receiving seat to move between the two material transfer lines of the device 2 300 to receive the watch case 10 processed by the device 2 300. Among them, the material receiving block may be recessed inward to form a receiving groove, and the receiving groove is used to accommodate the watch case 10.

[0071] Furthermore, if Figure 12 to Figure 13 As shown, in one embodiment, the third machine 401 is also equipped with a unloading component 440, and the unloading component 440 is used to clamp the watch case 10 and move it to the conveyor belt 100. The unloading component 440 includes a bracket 441 and a second gripper assembly 443. The bracket 441 is provided with a unloading and material transfer cylinder 442. The second gripper assembly 443 includes a second gripper hand 444, a second gripper cylinder 445 and a telescopic cylinder 446. The second gripper hand 444 is connected to the telescopic cylinder 446 through the second gripper cylinder 445, and the telescopic cylinder 446 is installed on the unloading and material transfer cylinder 442.

[0072] The second gripper hand 444 grips or releases the watch case 10 through the second gripper cylinder 445, and the telescopic cylinder 446 is used to control the second gripper hand 444 to descend or ascend, so as to grab and move the watch case 10. Driven by the material unloading and moving cylinder 442, the second gripper hand assembly 443 moves the watch case 10 that has been de-coated from the device 3 400 to the conveyor belt 100 or the material tray 20 on the conveyor belt 100. It can be understood that when the material tray 20 is used to convey the watch case 10, when the conveyor belt 100 moves to the device 1 200, the watch case 10 is grabbed by the loading module and brought into the device 1 200. After the coating is removed by the device 2 300 and the device 3 400 in sequence, the material tray 20 flows to the position of the conveyor belt 100 corresponding to the device 3 400, and the watch case 10 just completes the de-coating operation and is moved into the material tray 20 by the unloading assembly 440.

[0073] In one embodiment, the workflow of the assembly line may include the following steps. The tray 20 with the watch case 10 enters the conveyor belt 100 from the feed end, the material blocking cylinder on the conveyor belt 100 blocks the tray 20, and the CCD visual positioning component 110 takes a photo of the watch case 10 to obtain the product's position information and whether the side of the product to be processed is facing up. The loading module in the device 200 grabs the watch case 10 in the tray 20 and enters the device 200. In the process of moving to a storage table 278, the position of the product is adjusted. When the loading module grabs the watch case 10 in the tray 20 again, the barcode scanning gun component scans the QR code of the watch case 10 on the storage table 278; when the upward side of the product is not the product to be processed, a rotating component 270 flips the product. The jig lifting assembly 240 lifts up the first jig assembly 220, the jig pushing assembly 250 pulls open the connecting piece 227, the material moving assembly 290 simultaneously clamps the watch case 10 and moves it to the first jig assembly 220 for fixing and moves the watch case 10 that has been processed by the first jig assembly 220 to another storage table 278, the turntable 231 rotates, the first jig assembly 220 rotates to the working area, the first laser system 210 positions the product and removes the coating by laser; at this time, the material moving assembly 290 installs the watch case 10 on the other first jig assembly 220 on the turntable 231, and after the watch case 10 on the first jig assembly 220 is de-coated, the turntable 231 rotates, and another first jig assembly 220 rotates to the working area. After the processed watch case 10 is moved to another storage table 278, it is flipped by another rotating assembly 270 so that the other side to be processed faces upward.

[0074] The material transfer component 290 in the second device 300 clamps the watch case 10 to the material component in the second device 300. The material transfer component 290 clamps the watch case 10 to be processed and the completed watch case 10 at the same time, and the watch case 10 to be processed is moved to the second fixture component, and the completed watch case 10 is moved to another material component. The turntable 231 is rotated, and the second fixture component rotates to the working area of ​​the second laser system 310. The second laser system 310 positions the product and removes the coating by laser. The specific steps can refer to the first device 200. The completed watch case 10 is grabbed by the material transfer component 290 in another material component and transferred to the receiving component 450 in the third device 400.

[0075] The material moving component 290 in the third device 400 simultaneously clamps the watch case 10 on the receiving component 450 and the watch case 10 that has been processed by the third fixture component 420, and the watch case 10 on the receiving component 450 is moved to the third fixture component 420, and the watch case 10 that has been processed is moved to the waiting component. Specifically, the turntable 231 rotates, the third fixture component 420 rotates to the working area of ​​the third laser system 410, and the angle-tilted lifting cylinder 430 tilts and lifts the third fixture component 420, so that the surface groove of the watch case 10 on the third fixture component 420 is exposed, and the third laser system 410 locates the surface groove and removes the coating. Under the action of the unloading component 440, the watch case 10 that has been processed on the waiting component is moved to the material tray 20 on the conveyor belt 100, and the coating removal work on the front and back sides and the surface groove of a watch case 10 is completed.
