[0002] A thermally conductive silicone sheet die-cutting machine is a mechanical device specifically designed for the precise cutting of thermally conductive silicone sheets.

[0003] Currently, most existing devices may require manual flipping of the thermally conductive silicone sheet to complete the die-cutting, which increases the manual intervention step, reduces the continuity of processing, and may also affect the overall work efficiency due to inconsistent manual operation rhythm. In view of this, we propose a thermally conductive silicone sheet die-cutting machine. Utility Model Content

[0005] To achieve the above objectives, this utility model proposes a thermally conductive silicone sheet die-cutting machine, including an operating table with a slide groove, a die-cutting device and a feeding device on the operating table, the feeding device comprising: A rack, wherein the rack is connected to the inner wall of the groove; A moving block, wherein a rod is connected to the outer wall of the moving block, and a bearing is provided on the outer wall of the rod; A support platform, the inner wall of which is connected to the outer wall of the bearing, a fixing sleeve connected to the outer wall of the support platform, an elastic locking block on the fixing sleeve, a gear above the fixing sleeve, and a slot on the outer wall of the gear.

[0006] Preferably, the outer wall of the support platform is connected to a second bearing, and the outer ring of the second bearing is connected to the outer wall of the gear.

[0010] Preferably, there are four sets of grooves, which are distributed circumferentially on the outer wall of the support platform, and the number of grooves is the same as the number of elastic levers.

[0011] Preferably, there are four sets of slots, which are circumferentially distributed on the outer wall of the gear, and the number of slots is the same as the number of elastic blocks.

[0012] This invention provides a die-cutting machine for thermally conductive silicone sheets. It has the following beneficial effects: (1) The thermal conductive silicone sheet die-cutting machine achieves automatic 90-degree rotation after the thermal conductive silicone sheet is die-cut by means of gear and rack meshing transmission combined with elastic block and slot structure, which can prepare for the next die-cut without manual flipping, reducing manual intervention and making the processing flow more continuous and efficient.

[0013] (2) The thermal conductive silicone sheet die-cutting machine has a flexible clamping rod and groove structure that can provide additional positioning and clamping for the support table.

[0018] 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.

[0019] Please see Figures 1-6 This utility model proposes a thermally conductive silicone sheet die-cutting machine, including an operating table 1, which has a slide groove 11, and a die-cutting device 2 and a feeding device on the operating table 1.

[0020] In the embodiments of this utility model, in order to achieve the purpose of feeding hot silicone sheets, specifically, a rack 30 is connected to the inner wall of the slide groove 11, a rod 331 is connected to the outer wall of the moving block 33, the moving block 33 is penetrated by the screw 32 and cooperates with the screw 32, the end of the screw 32 is connected to the output end of the motor 31, a bearing 332 is provided on the outer wall of the rod 331, the inner wall of the support platform 34 is connected to the outer wall of the bearing 332, a fixing sleeve 35 is connected to the outer wall of the support platform 34, an elastic locking block 351 is provided on the fixing sleeve 35, a gear 342 is provided above the fixing sleeve 35, a slot 343 is opened on the outer wall of the gear 342, there are four sets of slots 343, and they are circumferentially distributed on the outer wall of the gear 342. The number of slots 343 is the same as the number of elastic locking blocks 351. A second bearing 341 is connected to the outer wall of the support platform 34, and the outer ring of the second bearing 341 is connected to the outer wall of the gear 342. Furthermore, the outer wall of the moving block 33 is connected to a housing 333, and the housing 333 is provided with an elastic locking rod 334. The outer wall of the support platform 34 is provided with a groove 340, which matches the elastic locking rod 334. There are four sets of grooves 340, which are circumferentially distributed on the outer wall of the support platform 34. The number of grooves 340 is the same as the number of elastic locking rods 334. In this invention, during use, the thermally conductive silicone sheet to be processed is first placed on the outer surface of the support platform 34. Then, the motor 31 is started, driving the screw 32 to rotate. Through the threaded engagement between the screw 32 and the moving block 33, the moving block 33 and the top support platform 34 are smoothly moved towards the die-cutting device 2. After the support platform 34 moves a certain distance with the moving block 33, the gear 342 at the bottom of the support platform 34 precisely meshes with the rack 30 on the equipment base. After meshing, the rack 30 exerts a horizontal force on the gear 342, forcing the gear 342 to rotate clockwise around its own axis. Figure 3 , Figure 4As shown, during the rotation of gear 342, slot 343 will contact the inclined surface of elastic block 351 and apply pressure, pushing elastic block 351 to move downward until elastic block 351 completely disengages from slot 343. At this time, gear 342 loses the limiting constraint of elastic block 351 and enters the idle state, rotating only with the movement of support table 34, no longer driving other structural actions. It continues to move until support table 34 drives the heat-conducting silicone sheet to the processing station of die-cutting device 2, and then the die-cutting device 2 is started, thus performing the die-cutting operation. After the thermally conductive silicone sheet is die-cut, the motor 31 is restarted. Through the reverse transmission of the screw 32, the moving block 33 and the support platform 34 are moved back to their initial positions. After the support platform 34 moves back a certain distance, the gear 342 at its bottom will mesh with the rack 30 again. At this time, under the force of the rack 30, the gear 342 rotates counterclockwise. During the rotation, the slot 343 will contact the right-angled edge of the elastic block 351 and apply a pushing force. Since the right-angled edge has no inclined guide, the elastic block 351 cannot avoid downward movement, thereby driving the fixed sleeve 35 connected to it and the support platform 34 above the fixed sleeve 35 to rotate synchronously. It should be noted that during the process from engagement to complete disengagement of the gear 342 and the rack 30, the gear 342 rotates exactly one-quarter of a turn. Therefore, the support platform 34 will drive the thermally conductive silicone sheet above it to rotate automatically by ninety degrees, without the need for manual turning, thus preparing it for the next die-cutting. This achieves automated turning of the silicone sheet after die-cutting, further improving the automation level and work efficiency of the processing flow. It should also be noted that the device is designed with a cooperative structure of elastic locking rod 334 and groove 340 at the connection between the support platform 34 and the moving block 33: the elastic locking rod 334 has a certain elasticity and will naturally lock into the groove 340 at the bottom of the support platform 34 during assembly, forming an additional positioning and clamping effect. The core function of this design is to increase the clamping force on the support platform 34: when the gear 342 rotates clockwise and the groove 343 applies a squeezing force to the inclined surface of the elastic locking block 351, the support platform 34 is easily subjected to external forces in the lateral or torsional direction. If the clamping is not stable, it may shift. However, the engagement of the elastic locking rod 334 and the groove 340 can firmly limit the displacement of the support platform 34 and prevent it from deviating in position during the force process.
