DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

Embodiment

[0025] Please refer to Figures 1 - 3, A copper foil lamination device for high-frequency copper clad laminate processing, including a base 1. Legs 2 are fixedly connected to the four corners of the bottom end of the base 1. The top end of the base 1 is connected to a mounting frame 3 through a support rod. Among them,

[0026] A motor 4 is installed at the bottom of the base 1. The output end of the motor 4 is fixedly connected to a worm 5. A support frame 6 is arranged outside the worm 5. The support frame 6 is connected to the bottom end of the base 1. The worm 5 penetrates through the side wall of the support frame 6 and is located inside the support frame 6. A turbine 7 is rotatably connected inside the support frame 6. The turbine 7 meshes with the worm 5;

[0027] In the middle of the top end of the turbine 7, a connecting rod 8 is fixed. The connecting rod 8 penetrates through the base 1 and extends to the top of the base 1. A turntable 9 is fixedly connected to the top end of the base 1. Two symmetrically arranged workbenches 10 are connected to the top end of the turntable 9. A first hydraulic group 11 and a second hydraulic group 13 are embedded at the top end of the mounting frame 3. A pressing plate 12 is fixedly connected to the bottom end of the first hydraulic group 11. A shearing plate 14 is fixedly connected to the bottom end of the second hydraulic group 13. A shearing frame 15 is arranged at the bottom of the shearing plate 14. The shearing plate 14 and the shearing frame 15 are disassembled and assembled through a clamping mechanism.

[0028] When processing the copper clad laminate, the robotic arm or the worker first places the workpiece on the workbench 10 directly below the pressing plate 12. The first hydraulic group 11 drives the pressing plate 12 to press down. After the pressing is completed, the motor 4 works. The motor 4 drives the turntable 9 to rotate 180° through the transmission structure between the worm 5 and the turbine 7, rotates the copper clad laminate to directly below the shearing plate 14, and presses down through the shearing frame 15 to trim the edge of the copper clad laminate, and can also cut the copper clad laminate into the required small block sizes at the same time. At the same time, the pressing plate 12 on the other side continues to work to press the next copper clad laminate. Through this lamination device, it is possible to directly trim and cut the workpiece without transporting the workpiece after lamination, effectively improving the processing efficiency of the copper clad laminate. After the shearing of the copper clad laminate is completed, the robotic arm or the worker removes the workpiece from the workbench 10.

[0029] Please refer to Figures 1 - 3 , The cross-section of the workbench 10 is rectangular. The positions of the two workbenches 10 correspond to those of the pressing plate 12 and the shearing plate 14 one by one. Two symmetrically arranged positioning grooves 16 are opened at the bottom end of the shearing plate 14. A positioning block 17 is fixedly connected to one end of the shearing frame 15 corresponding to the positioning groove 16. An opening groove 18 is opened at the side end of the shearing plate 14 close to the positioning groove 16. A spring 19 is fixedly connected to the inner wall of the opening groove 18. The other end of the spring 19 is fixedly connected to a pull rod 20. A clamping groove 21 is opened at one end of the positioning block 17 corresponding to the pull rod 20.

[0030] Please refer to Figure 3, the internal dimension of the positioning groove 16 matches the external dimension of the positioning block 17. A polishing layer is provided at the contact between the positioning groove 16 and the positioning block 17. The part of the pull rod 20 located in the opening groove 18 and the cross-section of the opening groove 18 are both L-shaped. The maximum horizontal length in the opening groove 18 is greater than the maximum horizontal length of the pull rod 20. One end of the pull rod 20 corresponding to the shearing frame 15 is provided with a slope, and the slope height gradually increases from the end of the pull rod 20 near the clamping groove 21 to the end near the spring 19.

[0031] When it is necessary to install the shearing frame 15, the positioning block 17 at the outer end of the shearing frame 15 can be moved into the positioning groove 16. The positioning block 17 contacts the pull rod 20 extending into the positioning groove 16. The slope height of the pull rod 20 gradually increases from the end near the clamping groove 21 to the end near the spring 19. Therefore, as the positioning block 17 moves, the pull rod 20 can gradually move into the interior of the opening groove 18. When the pull rod 20 is aligned with the clamping groove 21, the pull rod 20 snaps into the interior of the clamping groove 21 through the elastic connection formed with the spring 19, which is convenient for limiting the positioning block 17, thus achieving the purpose of quickly installing the shearing frame 15, so as to quickly cut copper clad laminates of different sizes.

[0032] Working principle: When the copper foil laminating device for high-frequency copper clad laminate processing is in use, first, select a suitable shearing frame 15 according to the size required for cutting during the processing of the copper clad laminate. Move the positioning block 17 at the outer end of the shearing frame 15 into the positioning groove 16. The positioning block 17 contacts the pull rod 20 extending into the positioning groove 16. The slope height of the pull rod 20 gradually increases from the end near the clamping groove 21 to the end near the spring 19. Therefore, as the positioning block 17 moves, the pull rod 20 can gradually move into the interior of the opening groove 18. When the pull rod 20 is aligned with the clamping groove 21, the pull rod 20 snaps into the interior of the clamping groove 21 through the elastic connection formed with the spring 19, which is convenient for limiting the positioning block 17, thus achieving the purpose of quickly installing the shearing frame 15;

[0033] After that, the robotic arm or the operator first places the workpiece on the workbench 10 directly below the pressing plate 12. The pressing plate 12 is driven by the first hydraulic group 11 to press down. After the pressing is completed, the motor 4 operates. The motor 4 drives the turntable 9 to rotate 180° through the transmission structure between the worm 5 and the turbine 7, rotates the copper clad laminate to directly below the shearing plate 14, and presses down the shearing frame 15 to trim the edge of the copper clad laminate and can also cut the copper clad laminate into small pieces of the required size at the same time. At the same time, the pressing plate 12 on the other side continues to work to press the next copper clad laminate. Through this laminating device, it is possible to directly trim and cut the workpiece without the need to transfer the workpiece after pressing, effectively improving the processing efficiency of the copper clad laminate. After the copper clad laminate is sheared, the robotic arm or the operator removes the workpiece from the workbench 10.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
