Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a vibration cutting device for processing thermal conductive silica gel. Background Art

[0002] Thermally conductive silicone sheets are a type of thermal conductive medium material synthesized through a special process using silicone as a base material and various auxiliary materials such as metal oxides. They are specially designed for heat transfer through gaps. They can fill gaps, open up thermal channels between heating parts and heat dissipation parts, effectively improve heat transfer efficiency, and also play the role of insulation, shock absorption, and sealing. They are an excellent thermal conductive filling material. Existing thermally conductive silicone sheets are cut after production, manually laid flat on a cutting table, and the two sides of the silicone sheet are attached to the cutting table with tape. Then, they are manually die-cut by the die-cutting machine head. Because the tape is not tightly fixed during the cutting process of the above structure, wrinkles may appear on the cut surface of the silicone sheet, thereby reducing the processing quality of the silicone sheet. At the same time, manual cutting cannot guarantee the straightness of the cutting and increases the workload of the staff.

[0003] The patent, with publication number "CN217802001U," is titled "A Cutting Device for Producing Thermally Conductive Silicone Sheets." While the device described in this publication addresses the aforementioned issues, the cutting disc in this device can only rotate unidirectionally when cutting the silicone sheet. When the silicone sheet is thick and hard, the disc can become stuck, affecting the cutting effect. This utility model addresses this issue by designing a vibrating cutting device for processing thermally conductive silicone sheets. Utility Model Content

[0026] The following will be combined with the accompanying 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. Example

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5As shown, the device includes an operating table 1 and a bracket 2. The bracket 2 is fixed on the top of the operating table 1. A driving component 3 is provided on the outer wall of the bracket 2. The driving component 3 includes an electric push rod 301 fixed to the middle end of the top of the bracket 2. A pull rod 302 fixed to the bottom of the electric push rod 301 passes through the bracket 2. A mounting plate 303 is fixed to the bottom of the pull rod 302. A slide plate 304 is slidably connected to the middle end of the bottom of the mounting plate 303. A serrated knife 305 is fixed to the bottom of the slide plate 304. A first motor 306 is fixed to the right side of the top of the mounting plate 303. A special-shaped rod 307 fixed to the bottom of the first motor 306 passes through the mounting plate 303. A connecting plate 308 is fixed to the right side of the outside of the slide plate 304. A guide hole 309 is integrated into the inside of the connecting plate 308. The guide hole 309 is a through hole design and is sleeved on the outside of the special-shaped rod 307.

[0028] A placement rack 4 is fixed on the left and right sides of the top of the operating table 1, and the distance between the two placement racks 4 is two centimeters. Mounting holes 5 are integrally provided on the left and right sides of the inside of the bracket 2. A splint 6 is slidably connected inside the mounting hole 5. A spring 7 is fixed between the bottom of the splint 6 and the mounting hole 5. A second motor 8 is fixed on the left and right sides of the upper end of the outside of the bracket 2, and the output end of the second motor 8 passes through the bracket 2. A cam 9 is provided on the external fixed sleeve of the output end of the second motor 8. The staff first places the silicone sheet on the top of the placement rack 4, so that the cutting area of ​​the silicone sheet and the serrated knife 305 coincide with each other, and then turns on the second motor 8. The second motor 8 drives the cam 9 to rotate, so that the cam 9 squeezes the silicone sheet to fix its position, and the spring 7 is deformed. Until the squeezing force of the cam 9 on the silicone sheet meets the staff's requirements, the staff first turns off the second motor 8, and then turns on the electric push rod 301 and the first motor 306. The electric push rod 301 pushes the pull rod 302 to drive the mounting plate 303 together with the serrated knife 305 to move along the direction of the silicone sheet. At the same time, the first motor 306 drives the special-shaped rod 307 to drive the guide hole 309 to link the connecting plate 308 together with the slide plate 304 and the serrated knife 305 to move back and forth in the direction of the mounting plate 303, thereby making the serrated knife 305 vibrate back and forth repeatedly to cut the silicone sheet. Through the above cutting method, the silicone sheet can be prevented from being stuck by the vibrating serrated knife 305, thereby ensuring the cutting efficiency of the silicone sheet. Example

[0029] like Figure 1 、 Figure 2 、 Figure 4As shown, an infrared sensor 10 is fixedly installed inside the placement rack 4, and the two infrared sensors 10 correspond to each other one by one. A top rod 11 is fixedly provided on the left side of the top of the mounting plate 303, and the top rod 11 and the mounting plate 303 are designed to be perpendicular to each other. A switch 12 is fixedly provided on the left side of the top end of the bracket 2, and the switch 12 and the top rod 11 are designed to correspond to each other one by one. A controller 13 is fixedly provided on the outer wall of the operating table 1, and the controller 13 is connected to the electric push rod 301, the first motor 306, the second motor 8, the infrared sensor 10 and the switch 12 through wires. The splint 6 is arranged at the upper end of the placement rack 4, and the distance between the bottom surface of the splint 6 and the top surface of the placement rack 4 is three centimeters. The front cross-section of the placement rack 4 is U-shaped, and the distance between the top surface of the placement rack 4 and the top surface of the operating table 1 is greater than the width of the side cross-section of the serrated knife 305.

[0030] According to the operation method in Example 1, after the silicone sheet is cut, until the serrated knife 305 blocks the path monitored by the infrared sensor 10, the electric push rod 301 starts the reset function. At this time, the electric push rod 301 pulls the pull rod 302 to drive the mounting plate 303 together with the first motor 306 and the serrated knife 305 to move in the opposite direction of the operating table 1 until the top rod 11 applies squeezing force to the switch 12. The electric push rod 301 and the first motor 306 stop running at the same time. In this way, the serrated knife 305 can be prevented from colliding with the operating table 1, thereby protecting the serrated knife 305 and the operating table 1.
