Description

Technical Field

[0001] This application relates to the field of thermally conductive silicone pad technology, and in particular to a preheating device for the production of thermally conductive silicone pads. Background Technology

[0002] Thermal conductive silicone pads are widely used in the electronics and semiconductor industries, playing an indispensable role in critical processes such as chip heat dissipation. These pads are synthesized using a special process with silicone as the base material and the addition of various auxiliary materials, including metal oxides. They possess excellent flexibility and compressibility, perfectly filling gaps of various shapes and sizes, creating efficient heat channels between heat-generating and heat-dissipating components, and significantly improving heat transfer efficiency. However, the production process of thermal conductive silicone pads faces numerous technical challenges. Among them, the preheating stage is particularly critical and complex. Without proper preheating, the uniformity of the raw material mixing in the thermal conductive silicone pad is difficult to guarantee, which directly affects its final thermal conductivity.

[0003] Traditional preheating devices for producing thermal conductive silicone pads typically preheat one side of the pad after clamping and fixing it. Then, the pad is manually flipped over and clamped again to preheat the other side. However, in actual operation, this process requires manual flipping and multiple adjustments to the pad's position, which is not only labor-intensive and time-consuming but also cumbersome and relatively inefficient.

[0011] Compared with the prior art, the beneficial effects of this application are as follows:

[0012] (1) This utility model proposes a preheating device for the production of thermally conductive silicone sheets. It is equipped with a worktable, an insulation shell, a support plate, a placement plate, a sealing cover, a rotating motor, a gear, a support block, and a clamping assembly. First, the thermally conductive silicone sheet is fixed to the placement plate by the clamping assembly. By rotating the motor, the placement plate changes state under the action of connecting rods 1 and 2 through the linkage of the rotating shaft, gear 1 and gear 2. In the initial state, the placement plate is set vertically and the sealing cover is separated from the insulation shell. Then, the thermally conductive silicone sheet that needs to be preheated is placed on the placement plate and fixed on the placement plate by the clamping assembly. Then, the rotating motor drives the placement plate to rotate to a horizontal state. At this time, the sealing cover is connected to the insulation shell through the linkage cover. The heating plate preheats the first side of the thermally conductive silicone sheet. Then, the rotating motor drives the placement plate to flip over and the heating plate preheats the other side of the thermally conductive silicone sheet. The heating plate on the sealing cover is always close to the surface of the thermally conductive silicone sheet when both sides of the thermally conductive silicone sheet are preheated, which improves the preheating effect of the thermally conductive silicone sheet.

[0013] (2) This utility model proposes a preheating device for the production of thermally conductive silicone sheets. It is equipped with a placement plate, two pull rods, two pressing plates, a connecting plate, a handle, and two buffer springs. In the initial state, the placement plate is vertical. First, manually pull the handle to move the connecting plate away from the placement plate, thereby stretching the buffer spring and driving the pressing plate to move. Then, the thermally conductive silicone sheet is placed into the placement plate through the placement port and aligned with the limiting groove. Then, the handle is released, and the spring force of the buffer spring allows the pressing plate to clamp the thermally conductive silicone sheet, preventing the thermally conductive silicone sheet from shaking during the flipping preheating and affecting the double-sided preheating effect.

[0014] (3) This utility model proposes a preheating device for the production of thermally conductive silicone sheets. By setting a support plate and a limiting block, the rotating motor rotates and drives the sealing cover away from the placement plate. When the top of the sealing cover contacts the limiting block, with the help of the torsion spring shaft, one end of the sealing cover approaches the limiting block and the other end moves away from the limiting block and rotates, increasing the operating space and making it easier to pick up, put down and fix the thermally conductive silicone sheet.

[0024] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] One preferred embodiment of this application, such as Figures 1 to 6 As shown, a preheating device for producing thermally conductive silicone sheets includes: a workbench 1, and further includes: a support plate 6, a placement plate 7, a sealing cover 8, a rotary motor 10, gears 12, a clamping assembly, and support blocks 16; there are two support plates 6, which are vertically fixedly installed on both sides of the top of the workbench 1; the placement plate 7 is arranged in a "U" shape and is located in the middle between the two support plates 6; the sealing cover 8 is located directly above the placement plate 7, and a heating plate 9 is fixedly installed on the inner wall of the top of the sealing cover 8; the rotary motor 10 is fixedly installed in the middle of the side of one of the support plates 6 away from the placement plate 7, and a rotating shaft 11 is fixedly installed in the middle of the outer walls on both sides of the placement plate 7, with the ends of the two rotating shafts 11 rotatably installed on the adjacent sides of the two support plates 6, and the end of one rotating shaft 11 away from the placement plate 7 is fixedly connected to the output shaft of the rotary motor 10; there are two gears 12, which are vertically fixedly installed on both sides of the workbench 1, and the two supporting plates 12 are ... Gear 12 is fixedly installed on the circumference of two rotating shafts 11. Gear 23 is rotatably installed on the back end of the adjacent side of the two support plates 16. Gear 12 is above gear 23 and meshes with the corresponding gear 23. Connecting rod 14 is fixedly installed on the edge of the circumference of the adjacent side of the two gears 23. Connecting rod 25 is rotatably installed on the end of the two connecting rods 14 away from gear 23. Clamping assembly is installed at the bottom end of the placement plate 7. There are two support blocks 16. The two support blocks 16 are rotatably installed on the outer wall of the other side of the sealing cover 8 through torsion spring shafts. Connecting rod 18 is horizontally fixedly installed on the top of the side of the two support blocks 16 away from each other. The circumference of the two connecting rods 18 is rotatably connected to the end of the corresponding connecting rod 25 away from the rotating shaft 11. The ends of the two connecting rods 18 away from each other are slidably installed on the back end of the adjacent side of the two support plates 16 through limiting sliding assemblies.

[0026] like Figure 4 The initial state is shown. The end of connecting rod 14 away from gear 2 13 is vertically upward, the end of connecting rod 2 15 away from rotating shaft 11 is vertically upward, and the placement plate 7 is in a vertical state. The thermal conductive silicone sheet is fixed on the placement plate 7 by the clamping assembly.

[0027] like Figure 3 The image shows the state where the sealing cover 8 is attached to the heat insulation shell 4. At this time, the heating plate 9 preheats the thermal conductive silicone sheet. The end of the connecting rod 14 away from the gear 2 13 is vertically downward, and the end of the connecting rod 2 15 away from the rotating shaft 11 is vertically upward. At this time, the placement plate 7 is in a horizontal state, and the heating plate 9 is close to the surface of the thermal conductive silicone sheet on the placement plate 7.

[0028] Next, the rotating motor 10 drives the placement plate 7 to rotate and flip over. During this process, the sealing cover 8 completes the process of opening and then sealing.

[0029] Further reference Figures 2-5 The clamping assembly includes: two pull rods 301, two clamping plates 302, a connecting plate 303, a handle 304, and two buffer springs 305. A limit groove is provided on the inner wall of the other end of the placement plate 7. A placement opening is provided at one end of the placement plate 7. Sliding openings are provided on both sides of the bottom end of the placement plate 7. The two pull rods 301 are respectively inserted into the corresponding sliding openings. The two clamping plates 302 are respectively fixedly installed at the end of the corresponding pull rod 301 located in the placement opening. The connecting plate 303 is horizontally fixedly installed between the ends of the two pull rods 301 located outside the placement opening. The handle 304 is fixedly installed at the center of the bottom of the connecting plate 303. The two buffer springs 305 are respectively sleeved on the outside of the corresponding pull rods 301. The top of the buffer spring 305 is fixedly installed to the placement plate 7, and the bottom of the buffer spring 305 is fixedly installed to the connecting plate 303. In the initial state, manually pull the handle 304. The handle 304 drives the connecting plate 303 to move away from the placement plate 7. At this time, the buffer spring 305 is stretched. As the connecting plate 303 moves, the two clamping plates 302 also move. Then, the thermal conductive silicone sheet is placed into the placement plate 7 through the placement port, and the bottom of the thermal conductive silicone sheet is aligned with the limiting groove. Next, release the handle 304. Under the elastic force of the buffer spring 305, the clamping plate 302 tightly adheres to the thermal conductive silicone sheet, firmly clamping it on the placement plate 7, thereby fixing the thermal conductive silicone sheet and preventing it from shaking during the flipping process, which would affect the double-sided preheating effect.

[0030] Further reference Figure 1 , Figures 3-5An insulation shell 4 is fixedly installed at the center of the top of the workbench 1. The top of the insulation shell 4 is engaged with the bottom edge of the sealing cover 8. In the preheating state, the bottom edge of the sealing cover 8 is engaged with the top of the insulation shell 4 to form a sealed and heat-insulating space. This ensures that when the heating plate 9 preheats the clamped thermally conductive silicone sheet, heat is not easily lost during the preheating process, improving the preheating effect and ensuring that the thermally conductive silicone sheet is heated evenly.

[0031] Further reference Figure 1 , Figure 3 and Figure 4 The limiting sliding assembly includes a slide rail 501 and a sliding block 502. The two slide rails 501 are vertically fixed to the top of the back end of one adjacent side of the two support plates 16. The sliding block 502 is slidably mounted on the slide rail 501. The sides of the two sliding blocks 502 that are close to each other are fixedly mounted to the ends of the two connecting rods 18 that are far from each other. When the rotating motor 10 is started, the end of the connecting rod 15 away from the rotating shaft 11 moves up and down, causing the support block 16 and the connecting rod 18 to slide up and down on the slide rail 501 via the sliding block 502. This causes the sealing cover 8 to move away from and closer to the placement plate 7. The slide rail 501 provides a vertical sliding track for the sliding block 502. Under the push of the connecting rod 15, the support block 16 slides along the slide rail 501 and remains relatively stable.

[0032] Further reference Figure 1 , Figure 3 and Figure 5 A second support plate 201 is fixedly installed between the top back ends of two adjacent support plates 16. Limiting blocks 202 are fixedly installed on both sides of the end of the second support plate 201 near the placement plate 7. When the sealing cover 8 moves away from the placement plate 7, the top end of the sealing cover 8 contacts the limiting block 202. Through the setting of the torsion spring shaft between the support block 16 and the sealing cover 8, the contact area between the sealing cover 8 and the limiting block 202 rotates, making the operating space between the sealing cover 8 and the insulation shell 4 larger, which facilitates the removal of the thermal conductive silicone sheet and the clamping and fixing operation of the thermal conductive silicone sheet.

[0033] Further reference Figure 1 and Figure 5 Both gear 12 and gear 2 13 are equipped with protective shells 17. These protective shells 17 can effectively protect gear 12 and gear 2 13 from external interference during operation, and also prevent operators from accidentally touching the high-speed rotating gears and causing danger, thus ensuring the stable operation of the equipment and the safety of personnel.

[0034] Working principle: In the initial state, the operator manually pulls the handle 304, which moves the connecting plate 303 away from the placement plate 7. During this process, the buffer spring 305 is stretched, and the two pull rods 301 connected to the connecting plate 303 slide in the sliding port, thereby driving the two clamping plates 302 to move accordingly. Then, the thermal conductive silicone sheet is placed into the placement plate 7 through the placement port, ensuring that the bottom of the thermal conductive silicone sheet is precisely aligned with the limiting groove. Then, the handle 304 is released. Under the elastic force of the buffer spring 305, the clamping plate 302 tightly adheres to the thermal conductive silicone sheet, firmly clamping it onto the placement plate 7, effectively preventing the thermal conductive silicone sheet from shaking during subsequent operations and ensuring the effect of double-sided preheating. The rotating motor 10 is started, driving the placement plate 7 to rotate. At the same time, through gear one 12, gear two 13, connecting rod one 14, and connecting rod two 15, The linkage mechanism moves the sealing cover 8 closer to the insulation shell 4 until the placement plate 7 is horizontal. The bottom edge of the sealing cover 8 engages with the top of the insulation shell 4, forming a sealed and insulated space to ensure that the thermally conductive silicone sheet is heated evenly. Then, the heating plate 9 begins to preheat the first side of the thermally conductive silicone sheet. After the preheating of the first side is completed, the rotating motor 10 is started and rotated 180 degrees to flip the placement plate 7. The rotating motor 10 is then stopped, and the sealing cover 8 rises and then falls, with its bottom edge engaging with the top of the insulation shell 4 again. Then, the heating plate 9 begins to preheat the second side of the thermally conductive silicone sheet. After the preheating of the second side is completed, the rotating motor 10 is started again and rotated 90 degrees before being stopped. The thermally conductive silicone sheet is then removed, achieving automatic flipping of the thermally conductive silicone sheet and double-sided preheating. The operation is convenient.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
