[0054] Among them, the workpiece can be a mobile phone frame equipped with a camera bracket. During the assembly process, the mobile phone frame can be fixed by a jig and the camera bracket can be pressed against the mobile phone frame from the outside. Then, after the jig is assembled on the workbench 30, the first hook assembly 40 and the second hook assembly 50 are extended into the inside of the camera bracket to hook the camera bracket from the inside, and then laser welding is performed from the inside of the camera bracket by laser, so that the camera bracket and the mobile phone frame are welded and fixed.

[0057] In this embodiment, the second cylinder 407 can drive the first sliding member 405 and the first hook member 406 to enter above the camera bracket, and then drive the first sliding seat 402 to move downward through the first cylinder 403, so that the first fixed plate 404, the first sliding member 405 and the first hook member 406 are driven to extend into the camera bracket, and by driving the first hook member 406 to move outward, the first hook member 406 is hooked on the inner side of the camera bracket to fix the inner support of the camera bracket, wherein an irregular shape is formed on the inner side of the camera bracket, and the first hook member 406 has a through hole adapted to the camera bracket, and when hooked with the camera bracket, it can be embedded with the inner side of the camera bracket, so that the adaptability is higher and the support is more stable and reliable.

[0058] Reference Figure 3 As shown, the second hook assembly 50 includes: a second fixed seat 501 is arranged on the workbench 30; a second sliding seat 502 is arranged on the second fixed seat 501 and can slide along a vertical plane perpendicular to the workbench 30; a third cylinder 503 is arranged on the second sliding seat 502 and is connected to the second fixed seat 501 to drive the second sliding seat 502 to slide on the second fixed seat 501; further, the second hook assembly 50 also includes: a second fixed plate 504 is arranged on the second sliding seat 502; two second sliding members 505 are arranged on the second fixed plate 504 and can slide along a parallel plane parallel to the workbench 30; two second hook members 506 are respectively connected to the two second sliding members 505 to slide respectively with the two second sliding members 505; two fourth cylinders 507 are arranged on the second fixed plate 504 and are respectively connected to the two second sliding members 505 to respectively drive the two second sliding members 505 and the two second hook members 506 to slide.

[0059] In this embodiment, the two fourth cylinders 507 drive the two second sliding members 505 and the two second hook members 506 to the workbench 30 and align them with the camera bracket, and then drive the second sliding seat 502 and the second fixed plate 504 to move downward through the third cylinder 503 to extend into the camera bracket, and then drive the two second hook members 506 to move outward and hook on the inner side of the camera bracket, so that the camera bracket can be hooked and positioned together with the first hook member 406, and then welding is performed, so that the welding is more stable and reliable; it can be understood that the second hook member 506 is also provided with a through hole adapted to the camera bracket, and when hooked with the camera bracket, it can be embedded with the inner side of the camera bracket to make the adaptability higher.

[0060] Reference Figure 4 and Figure 5As shown, a sliding plate 60 is provided between the base frame 10 and the workbench 30, and the sliding plate 60 and the base frame 10 are slidably connected. A driving cylinder is provided on the base frame 10, and the driving cylinder is connected to the sliding plate 60 to drive the sliding plate 60 to slide on the base frame 10. The sliding plate 60 can drive the workbench 30, the first hook assembly 40 and the second hook assembly 50 to rotate. When loading the jig, the workbench 30 can be moved to the loading position by the driving cylinder. After the jig is loaded, the driving cylinder drives the workbench 30 to the working position, thereby performing welding of the camera bracket, so that loading is simpler and more convenient.

[0061] Specifically, the rotating mechanism 20 includes a rotating cylinder 201, which is disposed at the bottom of the sliding plate 60. The rotating part 202 of the rotating cylinder 201 passes through the sliding plate 60 and is connected to the workbench 30 to drive the workbench 30 to rotate on the sliding plate 60. The rotating cylinder 201 can be a rotating cylinder 201 of the MSQ series of SMC. When the rotating cylinder 201 drives the workbench 30 to rotate, the jig loaded on the workbench 30 can rotate together, which can make the welding more precise and reliable when welding the camera bracket.

[0062] Furthermore, a fixing part 70 and a sensing part 80 are provided at the bottom of the rotating cylinder 201, and the fixing part 70 is provided at the bottom of the rotating cylinder 201; the sensing part 80 is connected to the fixing part 70 so as to move with the fixing part 70; wherein, a triggering part 90 is provided on the base frame 10, and the triggering part 90 and the sensing part 80 are in the same plane, and when the sensing part 80 moves to correspond to the triggering part 90, the triggering part 90 outputs a control signal.

[0063] In this embodiment, when the driving cylinder drives the sliding plate 60 and the workbench 30 to move to the loading position, the rotating cylinder 201 can slide with the sliding plate 60 so that the sensing member 80 provided on the rotating cylinder 201 is separated from the triggering member 90; when the sliding plate 60 and the workbench 30 are driven to slide to the working position, the rotating cylinder 201 slides to the working position with the sliding plate 60, so that the fixing member 70 can drive the sensing member 80 to correspond to the triggering member 90, and then the triggering member 90 can output a control signal to control the driving cylinder to stop, and then the workbench 30 stops at the working position; optionally, in some other embodiments, the driving cylinder can also be replaced by a linear motor or the like to drive the workbench 30 to slide, and the optional methods are more diverse.

[0064] Reference Figure 1 and Figure 4As shown, a damper 601 is provided on the sliding plate 60, and the damper 601 is on the same plane as the workbench 30, and is used to abut against the workbench 30 when the workbench 30 rotates to buffer the workbench 30. The rotary cylinder 201 drives the workbench 30 to form a 90-degree reciprocating rotation, so two dampers 601 can be provided, and after the workbench 30 rotates 90 degrees each time, the side of the workbench 30 can abut against the damper 601, so that the damper 601 can buffer the workbench 30, so that the stability of the workbench 30 is better, ensuring a more stable and reliable welding process.

[0065] Reference Figure 4 As shown, a limiter 301 for limiting the jig is provided at the edge of the workbench 30, and an air pipe joint 302 is provided on the workbench 30. The limiter 301 is connected with the air pipe joint 302 through a gas channel. When the gas channel is in a negative pressure state, the limiter 301 releases the restriction on the jig. When the gas channel is in a pressurized state, the limiter 301 abuts against the jig to limit the movement of the jig.

[0066] Among them, the limiting member 301 has a gas channel (not shown in the figure), and the workbench 30 is also provided with a gas channel to communicate with each other. The limiting member 301 is provided with a limiting portion 3011 that can be extended or retracted and closes the gas channel. Therefore, when the gas channel is in a negative pressure state, the limiting portion 3011 is retracted by the internal and external pressure difference; when the gas channel is in a pressurized state, the limiting portion 3011 is extended by the internal and external pressure difference. In this way, when the limiting portion 3011 is extended, it can be abutted against the fixture to restrict and fix the fixture; when the limiting portion 3011 is retracted, the fixture can be released from the restriction, and then the fixture can be disassembled.
