Description
Technical Field
[0001] The utility model relates to the technical field of graphite sheets, in particular to a clamping device for processing graphite sheets. Background Art
[0002] Graphite sheet is a new type of thermally conductive and heat-dissipating material with a unique grain orientation and lamellar structure. It can conduct heat evenly in two directions and adapt well to any surface. Graphite sheet has been widely used in many fields, including electronics, communications, lighting, aviation, and defense. In particular, in consumer electronics such as smartphones, ultra-thin PCs, and LED TVs, graphite sheet as a thermally conductive and heat-dissipating material has significantly improved product performance. Graphite sheet has high heat dissipation efficiency, eliminating "hot spots" and effectively managing heat distribution. Due to its lightweight design, graphite sheet takes up little space when dissipating heat, making it suitable for a variety of compact electronic devices. Graphite sheet also shields heat sources and components, protecting electronic devices from high-temperature damage. Furthermore, the surface of graphite sheet can be combined with materials such as metal, plastic, and self-adhesive adhesives to meet various design functions and requirements. To better adapt to the undulating surfaces of electronic devices and circuit modules, graphite thermally conductive sheets require certain processing methods. The main processing methods include backing adhesive and backing film treatment to enhance their adhesion and insulation properties. Therefore, the graphite sheet needs to be stably clamped to prevent tilting during processing.
[0003] However, the common graphite sheet clamping device has a relatively simple clamping method during use, which is inconvenient for clamping graphite sheets of different thicknesses, and it is inconvenient for lifting the clamped graphite sheet, which is not conducive to the processing of the graphite sheet;
[0004] Therefore, we propose a clamping device for graphite sheet processing to solve the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiments
[0030] This embodiment is a clamping device for processing graphite sheets.
[0031] like Figure 1 、 Figure 4 and Figure 5As shown, a support frame 2 is provided on the upper side of the loading platform 1, and a pressure plate 3 is rotatably connected to the inside of the support frame 2. The left side of the pressure plate 3 is rotatably connected to the connecting seat 4, and the connecting seat 4 is rotatably connected to the clamping plate 5. The right side of the pressure plate 3 is fixedly connected to the extension plate 6. The inside of the extension plate 6 is rotatably connected to a cylinder 7, and the internal thread of the cylinder 7 is connected to a threaded rod 8. The lower side of the threaded rod 8 is fixedly connected to a limiting plate 9, and the limiting plate 9 is connected to the limiting slot 10 by a slot. The limiting slot 10 is fixedly installed on the upper side of the loading platform 1, and the limiting slot 10 is symmetrical front to back about the vertical center axis of the limiting plate 9.
[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, a slot 11 is provided on the left side of the interior of the workbench 1, and an extension column 12 is slidably connected to the interior of the slot 11. The slot 11 and the extension column 12 are symmetrical front to back about the vertical center axis of the workbench 1. An extension plate 13 is fixedly connected to the left side of the extension column 12, and a connecting column 14 is fixedly connected to the lower side of the workbench 1. A limiting hole 15 is provided inside the connecting column 14, and the limiting holes 15 are distributed in an array. The connecting column 14 is slidably connected to the hollow column 16, and a mounting hole 17 is provided inside the hollow column 16. The mounting hole 17 is slidably connected to the insertion rod 18, and the insertion rod 18 is slidably connected to the limiting hole 15.
[0033] Need to explain Yes, if Figure 1 、 Figure 2 and Figure 3 As shown, the connecting seat 4 and the clamping plate 5 are rotatably connected. When the clamped graphite sheet is small, the longer side of the clamping plate 5 is parallel to the left side of the stage 1. When the clamped graphite sheet is small, the clamping plate 5 is rotated to make the shorter side of the clamping plate 5 parallel to the left side of the stage 1. Then, the extension plate 13 is pulled to the left to pull the extension column 12 out of the slot 11, thereby extending the loading area of the stage 1, thereby making it convenient to clamp a larger graphite sheet between the stage 1 and the clamping plate 5. Specific embodiments
[0034] This embodiment is intended to solve the problem of inconvenient clamping.
[0035] like Figure 1 、 Figure 4 and Figure 5 As shown, when the threaded rod 8 does not rotate, the pressure plate 3 will not rotate either. When the clamping plate 5 needs to clamp the graphite sheet, the threaded rod 8 is rotated. Since the threaded rod 8 is connected to the extension plate 6 through the cylinder 7, and the pressure plate 3 is restricted by the support frame 2, when the threaded rod 8 rotates, the pressure plate 3 on the left side of the support frame 2 will move up and down accordingly, making it convenient for the clamping plate 5 to be lifted and lowered.
[0036] Before clamping, the threaded rod 8 needs to be rotated to raise the left side of the pressure plate 3, thereby raising both the connecting seat 4 and the clamping plate 5. Then, the graphite sheet is placed on the upper side of the stage 1 so that its center is directly below the connecting seat 4. Then, the threaded rod 8 is rotated in the opposite direction to move the clamping plate 5 down to clamp the graphite sheet. In addition, since the vertical position of the threaded rod 8 relative to the stage 1 will change when the pressure plate 3 swings, the limit plate 9 on the lower side of the threaded rod 8 slides left and right in the limit groove 10 to play a limiting role. In addition, the cylinder 7 can rotate inside the extension plate 6, so that the cylinder 7 can prevent the threaded rod 8 from tilting, causing the limit plate 9 to be disconnected from the limit groove 10. Specific embodiments
[0037] This embodiment is to solve the problem of the inconvenience of lifting and lowering the loading platform 1.
[0038] like Figure 1 and Figure 6 As shown, when the loading platform 1 needs to be raised or lowered, a plurality of limiting holes 15 are opened inside the connecting column 14 for connecting the plug rod 18. First, the plug rod 18 is pulled out from the mounting hole 17, and then the loading platform 1 is lifted up or lowered, and the plug rod 18 is inserted from the mounting hole 17. The position of the mounting hole 17 and the limiting hole 15 are adjusted, and then the plug rod 18 is inserted until the plug rod 18 emerges from the mounting hole 17 on the rear side of the hollow column 16.
