Description

Technical Field

[0001] This utility model relates to the field of thermally conductive silicone pad production technology, and in particular to an apparatus for producing thermally conductive silicone pads. Background Technology

[0002] Thermally conductive silicone pads are flexible thermally conductive interface materials made of silicone as the base material and thermally conductive fillers such as alumina and boron nitride. They are mainly used to fill the gaps between heat-generating components and heat dissipation parts in electronic devices, reduce thermal resistance, improve heat conduction efficiency, and prevent equipment from being damaged or experiencing performance degradation due to localized overheating.

[0003] In the production process of thermal conductive silicone pads, if it is necessary to set air channels on the surface of the thermal conductive silicone pad for auxiliary heat dissipation, the thermal conductive silicone pad also needs to be grooved. For example, the utility model patent with authorization announcement number CN218947818U discloses a device for producing thermal conductive silicone pads.

[0004] Although the above-mentioned device can complete the grooving process of thermal conductive silicone pads, after completing the grooving process of the current thermal conductive silicone pad, it is necessary to manually remove it before placing the next thermal conductive silicone pad to be grooved. The interval between two adjacent grooving operations is relatively long, and the processing efficiency is not ideal. At the same time, the grooved thermal conductive silicone pads need to be manually removed, which is not convenient to use.

[0005] Therefore, it is necessary to invent an apparatus for producing thermally conductive silicone pads to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a device for producing thermally conductive silicone pads. This device can complete the output of the previous thermally conductive silicone pad and the input of the next thermally conductive silicone pad during the current grooving process, thereby effectively shortening the time interval between two adjacent grooving operations and improving processing efficiency. Furthermore, it utilizes gravity for active discharge of the thermally conductive silicone pads, making it more convenient to use. This addresses the problems mentioned in the background art, where after completing the grooving of the current thermally conductive silicone pad, it is necessary to manually remove it before placing the next pad to be grooved. The long interval between two adjacent grooving operations results in less than ideal processing efficiency, and the manual removal of the grooved thermally conductive silicone pads is inconvenient to use.

[0007] According to one aspect of this disclosure, the following technical solution is provided: an apparatus for producing thermally conductive silicone pads, comprising:

[0008] A receiving and collecting mechanism is used to receive the falling finished products;

[0009] A grooving mechanism, wherein the grooving mechanism is used for grooving a thermally conductive silicone pad; and

[0010] The positioning and conveying mechanism includes a column fixedly installed on the top of the workbench, a turntable fixedly sleeved on the outside of the column, a plurality of positioning plates uniformly fixedly nested on the outside of the turntable, a positioning channel adapted to a thermally conductive silicone pad being provided through the top of the positioning plate in a vertical direction, an upper clearance groove being provided between the positioning plate and the turntable, and the positioning and conveying mechanism also includes a lower clearance groove opened on the rear side of the top of the workbench and located directly below the adjacent upper clearance groove, and a drop opening opened on the right side of the top of the workbench.

[0011] An apparatus for producing thermally conductive silicone pads according to at least one embodiment of the present disclosure, wherein the receiving and collecting mechanism includes a worktable and a base is fixedly disposed on the bottom of the worktable.

[0012] An apparatus for producing thermally conductive silicone pads according to at least one embodiment of the present disclosure, wherein a finished product receiving box is placed on the rear side of the top of the base, the finished product receiving box being located directly below the lower clearance groove, and a debris collection box is placed on the right side of the top of the base, the debris collection box being located directly below the drop opening.

[0013] An apparatus for producing thermally conductive silicone pads according to at least one embodiment of the present disclosure, wherein the grooving mechanism includes an L-shaped fixing plate fixedly disposed on the rear side of a workbench, an electric push rod fixedly disposed on the back side of the L-shaped fixing plate, the output shaft of the electric push rod extending to the front side of the L-shaped fixing plate and fixedly connected to a U-shaped frame, and guide rods sliding through the L-shaped fixing plate fixedly disposed at both ends of the back side of the U-shaped frame.

[0014] An apparatus for producing thermally conductive silicone pads according to at least one embodiment of the present disclosure, wherein a rotating shaft is rotatably nested on the inner front end of the U-shaped frame via a bearing, a plurality of grooving cutters are uniformly fixedly mounted on the outer side of the rotating shaft, and a motor that is drively connected to the rotating shaft is fixedly mounted on the side of the U-shaped frame.

[0015] An apparatus for producing thermally conductive silicone pads according to at least one embodiment of the present disclosure, wherein a T-shaped top plate is fixedly disposed at the top of the L-shaped fixing plate, a diversion pipe connected to an air pump is fixedly disposed at the top of the T-shaped top plate, and a plurality of parallel inclined gas nozzles, each fixedly connected to the T-shaped top plate, are fixedly connected to the front of the diversion pipe.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a positioning and conveying mechanism that allows the turntable to rotate clockwise from the front or left side of the device. During this process, multiple positioning channels pass by the operator sequentially. As each channel passes the operator, multiple thermally conductive silicone pads to be slotted are placed into the inner side of the positioning channels for positioning. As the turntable continues to rotate, it moves the thermally conductive silicone pads to the slotting station adjacent to the slotting mechanism via the positioning plate. After the slotting mechanism completes the slotting of the thermally conductive silicone pads, it continues to rotate the turntable. Once the slotted thermally conductive silicone pads move above the drop opening, they fall under gravity, achieving output. Compared to existing technologies, this invention can complete the output of the previous thermally conductive silicone pad and the input of the next thermally conductive silicone pad during the current slotting process, thereby effectively shortening the time interval between two adjacent slotting operations and improving processing efficiency. In addition, the active discharge of the thermally conductive silicone pads using gravity makes it more convenient to use. Attached Figure Description

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture.

Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0027] Figure 1 This is a schematic diagram of the overall structure of an apparatus for producing thermally conductive silicone pads according to one embodiment of the present disclosure.

[0028] Figure 2 This is a partial structural diagram of the receiving and collecting mechanism 1, the grooving mechanism 2, and the positioning and conveying mechanism 3 of an apparatus for producing thermally conductive silicone pads according to one embodiment of the present disclosure.

[0029] Figure 3 This is a partial structural diagram of the positioning and conveying mechanism 3 of an apparatus for producing thermally conductive silicone pads according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the device for producing thermally conductive silicone pads disclosed herein, through the coordinated cooperation of the receiving and collecting mechanism 1, the grooving mechanism 2 and the positioning and conveying mechanism 3, can simultaneously complete the automatic unloading of the previous finished product and the loading of the next workpiece while the current thermally conductive silicone pad is being processed at the grooving station, greatly reducing the process interval. At the same time, with the assistance of gravity and airflow, the finished product and debris are separated and collected, reducing manual intervention.

[0031] like Figure 2As shown in this disclosure, the receiving and collecting mechanism 1 includes a workbench 11, which is made of Q235 cold-rolled steel plate to ensure load-bearing capacity (≥50kg) and flatness (error ≤0.5mm / m), and to avoid affecting the grooving accuracy due to table deformation during processing. A base 12 is fixedly installed at the bottom of the workbench 11, and a finished product receiving box 13 is placed on the rear side of the top of the base 12. It is made of PP plastic material (impact resistant and easy to clean) with a volume of 50L. The box has a handle on the outside for easy manual handling. The finished product receiving box 13 is located directly below the lower clearance groove 36. A debris collection box 14 is placed on the right side of the top of the base 12. It is also made of PP plastic material with a volume of 30L. The debris collection box 14 is located directly below the falling opening 37.

[0032] Therefore, the debris generated during the grooving process falls through the lower clearance groove 36 and is collected by the finished product receiving box 13, and the finished thermal conductive silicone pad after grooving falls through the falling opening 37 and is received by the debris collection box 14.

[0033] like Figure 2 As shown, in a preferred embodiment, the grooving mechanism 2 includes an L-shaped fixed plate 21 fixedly disposed on the rear side of the workbench 11, made of 6061 aluminum alloy (lightweight and high strength). An electric push rod 22 is fixedly disposed on the back of the L-shaped fixed plate 21; the model is DT300 (300mm stroke, 500N thrust, adjustable speed range 50-200mm / s). The output shaft of the electric push rod 22 extends to the front of the L-shaped fixed plate 21 and is fixedly connected to a U-shaped frame 23, which is welded from stainless steel. Guide rods 24, made of 45# steel, are fixedly disposed at both ends of the back of the U-shaped frame 23, sliding through the L-shaped fixed plate 21. The guide rods 24 have a chrome-plated surface, a roughness Ra≤0.8μm, and a clearance of 0.02-0.05mm between the guide rod and the L-shaped fixed plate 21. For guiding and anti-deflection purposes, a rotating shaft 25 is nested on the inner front end of the U-shaped frame 23 via a bearing. Multiple grooving cutters are evenly fixed on the outer side of the rotating shaft 25. The spacing between two adjacent cutters is adjusted according to design requirements and fixed with set screws to prevent loosening during high-speed rotation. A motor 26 connected to the rotating shaft 25 is fixed on the side of the U-shaped frame 23. A servo motor of model 130ST-M06025 is selected. A T-shaped top plate 27 is fixed on the top of the L-shaped fixed plate 21. A diversion pipe 28 connected to an air pump is fixed on the top of the T-shaped top plate 27. Multiple parallel inclined gas nozzles 29 are fixedly connected to the front of the diversion pipe 28 and are all fixedly connected to the T-shaped top plate 27. The inclined angle is set to 45° to face the grooving position to ensure that the airflow can cover the entire grooving area.

[0034] Therefore, after the thermally conductive silicone pad arrives at the grooving station, the electric push rod 22 drives the U-shaped frame 23, which is guided by the guide rod 24, to move forward continuously. At the same time, the motor 26 drives multiple grooving cutters to rotate continuously through the rotating shaft 25. As the U-shaped frame 23 moves forward continuously, the multiple grooving cutters groov the thermally conductive silicone pad. During this process, the air pump inputs airflow to multiple inclined gas nozzles 29 through the diversion pipe 28. The airflow continuously blows onto the thermally conductive silicone pad and the adjacent positioning plate 33, thereby causing the debris generated during the grooving process to continuously approach the adjacent upper clearance groove 35 along the positioning plate 33. Finally, it falls through the upper clearance groove 35 and the lower clearance groove 36. After the grooving is completed, the electric push rod 22 drives the U-shaped frame 23 to move backward and reset.

[0035] like Figure 2 and Figure 3 As shown in this disclosure, the positioning and conveying mechanism 3 includes a column 31 fixedly installed on the top of the workbench 11. A turntable 32 is fixedly sleeved on the outside of the column 31. The edge of the turntable 32 is provided with anti-slip texture to facilitate manual rotation by the operator. Multiple positioning plates 33 are uniformly fixedly nested on the outside of the turntable 32. The top of the positioning plate 33 is provided with a positioning channel 34 adapted to the thermal conductive silicone pad through the vertical direction. An upper clearance groove 35 is provided between the positioning plate 33 and the turntable 32. The positioning and conveying mechanism 3 also includes a lower clearance groove 36 opened on the rear side of the top of the workbench 11 and located directly below the adjacent upper clearance groove 35, and a drop opening 37 opened on the right side of the top of the workbench 11.

[0036] Therefore, the turntable 32 can be rotated clockwise from the front or left side of the device. During this process, multiple positioning channels 34 pass by the operator in sequence. When the positioning channel 34 passes by the operator, multiple thermal conductive silicone pads to be slotted are placed into the inner side of the multiple positioning channels 34 for positioning. As the turntable 32 continues to rotate, the turntable 32 moves the thermal conductive silicone pad to the slotting station adjacent to the slotting mechanism 2 through the positioning plate 33. After the slotting mechanism 2 completes the slotting of the thermal conductive silicone pad, it continues to rotate the turntable 32. After the slotted thermal conductive silicone pad moves to the top of the falling opening 37, it falls under the action of gravity, realizing the output. Compared with the existing technology, the output of the previous thermal conductive silicone pad and the input of the next thermal conductive silicone pad can be completed during the current slotting process, thereby effectively shortening the time interval between two adjacent slotting operations and improving processing efficiency. In addition, the active discharge of the thermal conductive silicone pad by gravity is more convenient to use.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
