A cutting device for processing thermal pads Technical Field

[0001] This utility model relates to the technical field of thermal pad processing equipment, and in particular to a cutting device for thermal pad processing. Background Technology

[0002] A thermal pad is a material used to conduct heat. It is commonly used in fields such as electronic devices. Its main purpose is to fill the gap between heat-generating components (such as CPU, GPU, and other chips) and heat dissipation devices (such as heat sinks or radiators) to help dissipate heat and improve the performance and stability of the device.

[0003] Thermal pads are usually large blocks after manufacturing, and then need to be cut according to the shape of the required electronic device. However, most existing cutting equipment is done manually, which is inefficient and has large processing errors. As a result, the thermal pad cannot fit the surface of the required electronic device perfectly. To address this, we propose a cutting device for thermal pad processing. Summary of the Invention

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As shown in Figures 1-3, this embodiment provides a cutting device for processing thermal pads, including:

[0026] Workbench 1, at least one set of guide members are vertically fixed on the workbench 1, each set of guide members includes two second rods 16, and the top of the second rods 16 is connected to a connecting plate 17 arranged parallel to the table surface of the workbench 1.

[0027] The second cylinder 20 is fixedly connected to the connecting plate 17;

[0028] The cutting assembly includes a second plate 19 that can slide along the axial direction of the rod and a cutting mold 6 connected to the second plate 19. The second plate 19 is connected to a second cylinder 20. The second cylinder 20 can drive the cutting mold 6 to move up and down along the axial direction of the second rod 16 through the second plate 19 to realize the cutting of the heat-conducting pad.

[0029] The first cylinder 11 is fixedly connected to the worktable 1;

[0030] The clamping mechanism 4 includes a first plate 10 connected to the first cylinder 11 and a positioning frame 13 parallel to the first plate 10. The first plate 10 is connected to the positioning frame 13 through a first rod 9 that passes through and is perpendicular to the workbench 1 surface. The first cylinder 11 can drive the clamping mechanism 4 to move up and down along the first rod 9 to fix the heat-conducting pad to be processed.

[0031] Overall, the thermal pad to be cut is placed on the bearing station 3 of the workbench 1. The first cylinder 11 drives the first plate 10 to descend vertically, so that the first rod 9 and the positioning frame 13 move with the first plate 10, so that the positioning frame 13 abuts against the upper surface of the thermal pad to fix the thermal pad to be processed. After fixing, the second cylinder 20 drives the cutting mold 6 to move downward along the second rod 16 axially through the second plate 19 until the cutting mold 6 completes the cutting of the thermal pad. After the cutting of the thermal pad is completed, the second cylinder 20 drives the cutting mold 6 to move upward along the second rod 16 axially through the second plate 19 and removes the thermal pad from the cutting mold 6.

[0032] The automatic operation of pressing and cutting is achieved by the coordinated drive of the first cylinder 11 and the second cylinder 20, which can effectively improve the cutting efficiency of the heat-conducting pad; and by realizing the modular design between the cutting mold 6 and the second plate 19, it can be adapted to the processing of heat-conducting pads of different shapes, thereby improving the overall applicability of the device.

[0033] Furthermore, it can also achieve the adaptation between the positioning frame 13 and the heat-conducting pad to be processed, which can not only achieve uniform pressure on the positioning frame 13 during the fixing process, but also fix the heat-conducting pad according to different shapes.

[0034] When placing the thermal pads to be processed on the bearing station 3, the thermal pads can be stacked according to the actual situation and fixed by the positioning frame 13. The number of thermal pads to be processed can be stacked reasonably according to the actual length, width and height of the thermal pads to be processed, and there is no limit to this.

[0035] As shown in Figures 1-2, this embodiment also includes a stripping mechanism 7. The stripping mechanism 7 includes a third plate 21 fixedly connected to the connecting plate 17, a telescopic rod 22 parallel to the axis of the second rod 16, and a connecting block 12 fixedly connected to the end of the telescopic rod 22. The second plate 19 has a groove 5 that matches the connecting block 12, so that the connecting block 12 passes through the groove 5 to strip the heat-conducting pad in the cavity of the cutting mold 6.

[0036] Specifically, after the heat-conducting pad is cut, the second cylinder 20 drives the cutting mold 6 to move upward along the second rod 16 through the second plate 19. The telescopic rod 22 is stretched to allow the connecting block 12 to pass through the groove 5 to remove the heat-conducting pad in the cavity of the cutting mold 6, so that the material is automatically ejected, which improves the material removal efficiency and avoids material residue from affecting the next cutting process.

[0037] Furthermore, a buffer pad can be added to the end of the connecting block 12 to avoid damage to the cutting mold 6 caused by rigid impact during material removal, thereby extending the service life of the cutting mold 6.

[0038] As shown in Figures 1-2, in this embodiment, the unloading mechanism 7 further includes a telescopic rod 22 fixed to the connecting plate 17 and a connecting block 12 fixed to the end of the telescopic rod 22.

[0039] The specific unloading mechanism 7 also includes a telescopic rod 22 fixed to the connecting plate 17 and a connecting block 12 fixed to the end of the telescopic rod 22, which can unload the material in the cutting mold 6 cavity directly below the connecting block 12.

[0040] As shown in Figures 2-3, in this embodiment, the clamping mechanism 4 further includes a plurality of mounting blocks 14 arranged circumferentially along the positioning frame 13 and a plurality of balls 15 arranged in a one-to-one correspondence with the plurality of mounting blocks 14.

[0041] Specifically, the clamping mechanism 4 also includes a plurality of mounting blocks 14 arranged circumferentially along the positioning frame 13 and a plurality of balls 15 arranged one-to-one with the plurality of mounting blocks 14. When the first cylinder 11 drives the clamping mechanism 4 to move down to position the heat-conducting pad to be processed, the heat-conducting pad deforms. Through the arrangement of the balls 15, the friction between the clamping mechanism 4 and the heat-conducting pad to be processed changes from sliding friction to rolling friction. Due to the reduction of the friction between the heat-conducting pad and the clamping mechanism 4, the downward resistance of the clamping mechanism 4 can be effectively reduced.

[0042] As shown in Figures 1 and 2, this embodiment also includes a support foot 2, which includes a threaded rod and a base. The threaded rod is threadedly connected to the worktable 1 to realize the lifting and lowering adjustment of the worktable 1.

[0043] By setting support feet 2 at the bottom of the workbench 1, the height of the workbench 1 can be adjusted, and the overall height of the device can be prevented from shifting during the processing, ensuring the accurate positioning of the heat-conducting pad during long-term processing.

[0044] As shown in Figures 1-2, in this embodiment, a sleeve 8 is embedded in the workbench 1 and arranged concentrically with the first rod 9, and a sliding sleeve 18 is embedded in the second plate 19 and arranged concentrically with the second rod 16.

[0045] Specifically, by concentrically arranging the sleeve 8 and the first rod 9, the deviation generated during the axial movement of the pressing mechanism 4 along the first rod 9 can be reduced, thereby reducing the horizontal friction and avoiding positional deviation during positioning. Conversely, by concentrically arranging the sliding sleeve 18 and the second rod 16, the deviation generated during the axial movement of the cutting die 6 along the second rod 16 can be reduced, thereby improving the cutting accuracy of the heat-conducting pad.

[0046] As shown in Figures 1-2, in this embodiment, the inner walls of both the sleeve 8 and the sliding sleeve 18 are provided with a self-lubricating layer. The self-lubricating layer is made of polytetrafluoroethylene composite material and forms a clearance fit with the corresponding rod.

[0047] Specifically, the self-lubricating layer prevents jamming and eliminates the need for additional lubrication maintenance.

[0048] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention.

This narrative style is merely for clarity.
