[0047] A module mounting plate 2031 is fixedly connected to the bottom of the first slide plate 203 along the X direction, and the second linear motor 301 and the second guide rail 302 are symmetrically arranged side by side up and down, and are arranged on the module mounting plate 2031 at intervals along the X-axis direction; one end of the second slide plate 303 is connected to the driving end of the second linear motor 301, and the other end is connected to the slider and is slidably connected to the second guide rail 302.

[0048] The rotating module 400 is connected to the second slide plate 303. The clamping jaw suction assembly 500 is connected to the moving end of the rotating module 400. The second linear module 300 drives the rotating module 400 and the clamping jaw suction assembly 500 to move along the X-axis direction, and the rotating module 400 adjusts the rotation angle of the clamping jaw suction assembly 500.

[0050] The clamping jaw suction assembly 500 includes a clamping jaw mounting plate 501, and the upper surface of the clamping jaw mounting plate 501 is fixedly connected to the driving end of the rotating motor. In this specific embodiment, the clamping jaw mounting plate 501 is a rectangular plate, and its length direction is arranged along the X direction. A pair of suction cup clamping jaw assemblies 502 are symmetrically arranged along the X direction on the bottom surface of the clamping jaw mounting plate 501. Each suction cup clamping jaw assembly 502 includes a suction cup plate 503, a clamping jaw linear module 504 arranged along the Z-axis direction, and a plurality of vacuum suction cups 505, wherein the suction cup plate 503 is a rectangular plate, and its length direction is perpendicular to the length direction of the clamping jaw mounting plate 501 when it is arranged. The rotating motor rotates on a horizontal plane with the center of the length direction of the clamping jaw mounting plate 501 as the rotation center to adjust the rotation angle of the suction cup plate 503.

[0051] Each suction cup plate 503 is provided with a side baffle 508 on the bottom surface facing the heat conducting plate 800 at both sides along the Y-axis direction. Preferably, a soft pad is provided on the bottom surface of each side baffle 508 abutting against the heat conducting plate 800 to prevent the heat conducting plate 800 from being scratched and damaged.

[0052] Each clamping jaw linear module 504 is a linear drive cylinder. The fixed ends of the two clamping jaw linear modules 504 are respectively fixed to the two ends of the length direction of the clamping jaw mounting plate 501 through connecting plates. The driving end of each clamping jaw linear module 504 is connected to the aforementioned suction cup plate 503. Each suction cup plate 503 faces the bottom surface of the heat conducting plate 800 and is located between the baffles 508 on both sides.

Each suction cup plate 503 sucks one heat conducting plate 800 at a time.

[0053] Each clamping jaw linear module 504 can independently drive its corresponding suction cup plate 503 to move along the Z-axis direction. When the clamping jaw suction assembly 500 runs above the thermal conductive sheet 800 to be loaded, each clamping jaw linear module 504 on a pair of suction cup clamping jaw assemblies located on the clamping jaw suction assembly 500 drives each suction cup plate 503 to move downward, and the vacuum suction cup 505 connected to the suction cup plate 503 simultaneously moves downward to the surface of the thermal conductive sheet 800, and the vacuum generator is started.

When each floating plate linear module 506 is in an unactivated position, the bottom surface of each vacuum suction cup 505 and the bottom surface of each side baffle 508 are located on the same plane. In this arrangement, when the vacuum suction cup 505 absorbs the heat conductive sheet 800, the two top ends of the heat conductive sheet 800 along the Y-axis direction are just placed on the soft pads of the two side baffles 508.

[0055] Each floating plate linear module 506 can independently drive its corresponding floating plate 507 and the vacuum suction cup 505 on the floating plate 507 to move along the Z-axis direction.

[0056] When the thermal conductive sheet 800 moves to above the bracket 900, the floating plate linear module 506 is started, and the floating plate 507 and the vacuum suction cup 505 on the floating plate 507 are lowered to the bracket 900 with the thermal conductive sheet 800, and the vacuum generator is turned off, and the thermal conductive sheet 800 is placed on the bracket 900, completing the assembly action.

[0057] In addition, as a preference, the distance between a pair of suction cup jaw assemblies 502 symmetrically spaced apart on the jaw mounting plate 501 is sufficient to accommodate a suction cup jaw assembly, so as to meet the need for taking materials at intervals during actual production.

[0058] The frame 100 is also provided with a heat conducting sheet cache station 103 for storing the heat conducting sheets 800 to be loaded and assembled. In the utility model, four heat conducting sheets 800 can be stored in the heat conducting sheet cache station 103 at the same time.

[0059] The first detection component 600 is provided on the frame 100, where the clamp suction component 500 moves from the storage place of the thermal conductive sheet 800 to the path of the first conveying mechanism 101. The first detection component 600 includes a CCD camera with a shooting surface facing upward and a light source along the shooting angle of the CCD camera. In the utility model, two first detection components 600 are provided between the first conveying mechanism 101 and the thermal conductive sheet carrier buffer station 103, and each detection component 600 corresponds to detecting the position of the thermal conductive sheet 800 located on a suction cup plate 503 on the above-mentioned clamp suction component 500, and each detection component 600 is located below each suction cup plate 503, and each first detection component 600 detects and locates the position of the thermal conductive sheet 800 by shooting the positioning hole on the corresponding thermal conductive sheet 800 at an upward shooting angle.

[0060] A linear moving module B701 with a driving direction along the X-axis direction is provided on the frame 100 above the side of the first conveying mechanism 101 away from the heat conducting plate buffer station 103. A second detection component 700 is provided on the linear moving module B701. The second detection component 700 includes a CCD camera with a shooting surface facing downward and a light source along the shooting angle of the CCD camera. The linear moving module B is the same as the first linear module 200 described above, including a linear motor B, a guide rail B and a slider, and the specific connection relationship is not repeated here. The second detection component 700 is driven by the linear moving module B701 to move along the X-axis direction, and takes pictures of the positioning holes on the bracket 900 to detect the position of each bracket 900 on the assembly vehicle 102.

[0064] S2, assembly positioning: During the process of transferring the clamping jaw suction component 500 with the heat conductive sheet 800 to the assembly vehicle 102, the two first detection components 600 respectively take photos of the two heat conductive sheets 800 on the clamping jaw suction component 500 for position detection; the clamping jaw suction component 500 with the heat conductive sheet 800 is transferred to the top of the assembly vehicle 102, and at the same time, the second detection mechanism 700 moves with the linear moving module B701 to the top of a bracket 900 on the assembly vehicle 102, and the second detection mechanism 700 takes photos of the bracket 900 for position detection; the control system combines the position detection information of the first detection component 600 and the second detection component 700 to obtain The corresponding relationship between the heat conductive sheet 800 and its corresponding bracket 900, if there is a position size deviation in the hole position where the two are assembled, the rotating motor drives the suction cup plate 503 and the heat conductive sheet 800 on the vacuum suction cup 505 to slightly rotate according to the position size deviation information to adjust the direction of the heat conductive sheet 800 so that it can be accurately aligned with the corresponding bracket 900; in addition, the first linear module 200 and the second linear module 300 can also drive the heat conductive sheet 800 to change the distance along the Y axis or along the X axis according to the position size of the heat conductive sheet 800 and its corresponding bracket 900 to adjust the position of the heat conductive sheet 800 so that it can be accurately aligned with the corresponding bracket 900;
