Description

Technical Field

[0001] This utility model relates to the field of thermally conductive adhesive application technology, and in particular to a thermally conductive adhesive application device. Background Technology

[0002] Thermally conductive adhesive is used to fill the gap between heating elements and heat dissipation devices. Its main functions include: efficiently conducting heat, transferring heat from the heating element to the heat dissipation device, reducing its temperature, and ensuring stable and reliable operation of the equipment; filling the microscopic gaps on the surfaces of both, reducing thermal resistance, and improving heat conduction efficiency; using its elasticity and flexibility to absorb shock and buffer, reducing stress caused by mechanical vibration and thermal expansion, and protecting the components and equipment; some thermally conductive adhesives have excellent insulation properties, which can isolate the heating element from metal parts, prevent short circuits, and are suitable for scenarios with high insulation requirements; it can also form a sealed environment, blocking dust and moisture, preventing components from being corroded and short-circuited, and extending the service life of the equipment.

[0003] Patent publication number "CN219664221U" discloses "a thermally conductive adhesive applicator," comprising: a worktable, on which mounting plates are fixedly installed on both sides, a mounting groove is formed on one side of the mounting plate, a fixing block is fixedly installed on one side of the mounting plate, and a connecting plate is fixedly installed on the top surface of the mounting plate; and an applicator assembly disposed on the top surface of the worktable for applying thermally conductive adhesive to battery cooling plates. By setting the applicator assembly, thermally conductive adhesive can be automatically applied to the cooling plates placed on the top surface of the worktable, saving time and effort, and ensuring uniform application of the thermally conductive adhesive. The thermally conductive adhesive can adhere evenly to its surface, improving applicator efficiency and thus increasing the production efficiency of battery cooling plates. By setting a second drive motor, when the second drive motor is started, the clamping plate moves on the surface of the worktable to clamp and fix the cooling plates on the surface of the worktable, so that the cooling plates do not change position during the applicator process.

[0004] After the device in the aforementioned patent completes the application of thermally conductive adhesive to the sheet material, if the sheet material is handled by hand, it is very easy for the sheet material to tilt due to improper operation or uneven force during the handling process. Once the sheet material tilts, the thermally conductive adhesive already applied to the sheet material is very likely to leak along the tilt direction due to its certain fluidity. This will not only waste the thermally conductive adhesive, but may also pollute the surrounding working environment. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a thermally conductive adhesive application device.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a thermally conductive adhesive application device, comprising a frame, a moving mechanism disposed inside the frame, a control mechanism disposed above the moving mechanism, and an auxiliary mechanism disposed above the control mechanism;

[0009] The moving mechanism includes a first servo motor and a rotating roller. One end of the rotating roller is fixedly installed at the output end of the first servo motor, and the other end of the rotating roller is fixedly installed with a rotating wheel. A belt is wound around the outer side of the rotating wheel. An auxiliary roller is rotatably connected to the inner wall of one side of the frame, and one end of the auxiliary roller is rotatably connected to the inner wall of the other side of the frame.

[0010] By adopting the above technical solution, the rotating rollers smoothly move the sheet material after the thermal conductive adhesive has been applied, avoiding the risk of the sheet material tilting due to uneven force when handled directly. This prevents the freshly applied thermal conductive adhesive from leaking along the tilt direction. Furthermore, thanks to the synergistic effect of the rotating rollers and auxiliary rollers, even if a small amount of thermal conductive adhesive overflows, it falls smoothly, effectively preventing waste and pollution caused by leakage. This ensures the coating quality of the thermal conductive adhesive on the sheet material and solves the problem that if the sheet material is handled by hand, it is easy for improper operation or uneven force to cause the sheet material to tilt. Once the sheet material tilts, the thermal conductive adhesive already applied to it, due to its fluidity, is very likely to leak along the tilt direction, not only wasting the thermal conductive adhesive but also potentially polluting the surrounding working environment.

[0011] In a preferred embodiment of the thermally conductive adhesive application device of this utility model, the control mechanism includes a second servo motor and a bidirectional screw. One end of the bidirectional screw is fixedly installed at the output end of the second servo motor, and a control plate is screwed onto the outer side of the bidirectional screw. First limit rods are fixedly installed on both sides of the control plate.

[0012] By adopting the above technical solution, the rotating bidirectional screw can effectively drive the control plates screwed to the outside to move. The moving control plates can effectively clamp plates of different widths, preventing problems such as positional displacement during painting.

[0013] In a preferred embodiment of the thermally conductive adhesive application device of the present invention, one end of the rotating roller of the moving mechanism is rotatably connected to the inner wall of one side of the frame and the surface of the other side, and the other end of the rotating roller is rotatably connected to the inner wall of the other side of the frame and the surface of the other side. A collection frame is provided below the rotating roller.

[0014] By adopting the above technical solution and setting a collection frame below the rotating roller, the thermally conductive adhesive dripping from the rotating roller and the sheet can be collected efficiently, avoiding waste of thermally conductive adhesive and environmental pollution.

[0015] In a preferred embodiment of the thermally conductive adhesive application device of this utility model, one end of the bidirectional screw of the control mechanism is rotatably connected to the inner wall of one side of the frame, and the other end of the bidirectional screw is rotatably connected through the inner wall of the other side of the frame and the surface of the other side. One end of the first limiting rod is slidably connected through the inner walls of both sides of the frame and the surfaces of both sides respectively.

[0016] By adopting the above technical solution, the frame can effectively provide a stable rotational connection effect for the bidirectional screw that is rotatably connected to the inner wall on one side.

[0017] In a preferred embodiment of the thermally conductive adhesive application device of this utility model, a storage box is fixedly installed on the surface of the frame, and a spray nozzle penetrating the bottom wall is fixedly installed on the top surface of the storage box. One end of the spray nozzle penetrates the top surface and the top wall of the storage box, and one end of the collection frame penetrates one side surface and one side inner wall of the frame and is inserted into the other side inner wall.

[0018] By adopting the above technical solution, when the internal equipment of the storage box is started, the thermally conductive adhesive that needs to be applied inside the box will be discharged from the spray nozzle installed on the bottom surface and penetrating the bottom wall, thereby achieving precise and efficient spraying operations.

[0019] In a preferred embodiment of the thermally conductive adhesive application device of this utility model, the auxiliary mechanism includes a hydraulic cylinder. One end of the hydraulic cylinder is fixedly installed on the top surface of the storage tank, and the output end of the hydraulic cylinder penetrates through the top surface and the top wall of the storage tank. A scraper is fixedly installed on the output end of the hydraulic cylinder, and a second limiting rod is fixedly installed on the surface of the scraper. One end of the second limiting rod is slidably connected through the top wall and the top surface of the frame.

[0020] By adopting the above technical solution, after the hydraulic cylinder is started, it can accurately push the scraper installed at its output end to move down smoothly. During the downward movement, the scraper can evenly scrape the surface of the coated board, so that the thermally conductive adhesive can be more evenly adhered to the surface of the board, significantly improving the coating efficiency and quality.

[0021] (III) Beneficial Effects

[0022] This invention provides a thermally conductive adhesive application device. It has the following beneficial effects:

[0023] 1. By adding a moving mechanism, the rotating rollers smoothly move the sheet material after the thermal conductive adhesive has been applied, avoiding the risk of the sheet material tilting due to uneven force when handled directly. This prevents the freshly applied thermal conductive adhesive from leaking along the tilt direction. Furthermore, thanks to the synergistic effect of the rotating rollers and auxiliary rollers, even if a small amount of thermal conductive adhesive spills, it falls smoothly, effectively preventing waste and pollution caused by leakage. This ensures the coating quality of the thermal conductive adhesive on the sheet material and solves the problem that if the sheet material is handled by hand, improper operation or uneven force can easily cause it to tilt. Once the sheet material tilts, the thermal conductive adhesive already applied, due to its fluidity, is very likely to leak along the tilt direction, resulting in waste of thermal conductive adhesive and potential pollution of the surrounding working environment.

[0024] 2. By adding an auxiliary mechanism, the hydraulic cylinder can be activated to precisely push the scraper installed at its output end to move smoothly downward. During the downward movement, the scraper can evenly scrape the surface of the coated board, making the thermally conductive adhesive adhere more evenly to the board surface, significantly improving coating efficiency and quality.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Reference Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment provides a thermally conductive adhesive application device including a frame 1, a moving mechanism 2 is provided inside the frame 1, a control mechanism 3 is provided above the moving mechanism 2, and an auxiliary mechanism 6 is provided above the control mechanism 3.

[0034] The moving mechanism 2 includes a first servo motor 22 and a rotating roller 21. One end of the rotating roller 21 is fixedly installed at the output end of the first servo motor 22, and the other end of the rotating roller 21 is fixedly installed with a rotating wheel 23. A belt 24 is wound around the outside of the rotating wheel 23. An auxiliary roller 25 is rotatably connected to the inner wall of one side of the frame 1. One end of the auxiliary roller 25 is rotatably connected to the inner wall of the other side of the frame 1.

[0035] Specifically, the control mechanism 3 includes a second servo motor 32 and a bidirectional screw 31. One end of the bidirectional screw 31 is fixedly installed at the output end of the second servo motor 32. A control plate 33 is screwed onto the outer side of the bidirectional screw 31. A first limit rod 34 is fixedly installed on both sides of the control plate 33. One end of the rotating roller 21 of the moving mechanism 2 is rotatably connected to one side of the inner wall and one side of the frame 1. The other end of the rotating roller 21 is rotatably connected to the other side of the inner wall and the other side of the frame 1. A collection frame 7 is provided below the rotating roller 21. One end of the bidirectional screw 31 of the control mechanism 3 is rotatably connected to one side of the inner wall of the frame 1. The other end of the bidirectional screw 31 is rotatably connected to the other side of the inner wall and the other side of the frame 1. One end of the first limit rod 34 is slidably connected to the inner walls and the two sides of the frame 1.

[0036] Furthermore, the moving mechanism 2 drives the rotating roller 21 to rotate via the first servo motor 22. The rotating roller 21 drives the rotating wheels 23 installed at the other end to rotate. The rotating wheels 23 effectively drive the outer belt 24 to rotate. The rotating belt 24 effectively drives the multiple rotating rollers 21 to rotate respectively. The rotating rollers 21 smoothly move the board material after the thermal conductive adhesive has been applied out, thus avoiding the board material tilting due to uneven force when directly picked up. The freshly applied thermal conductive adhesive is very likely to leak in the tilt direction. At the same time, thanks to the synergistic effect of the rotating roller 21 and the auxiliary roller 25, even if a small amount of thermal conductive adhesive overflows, it can fall smoothly, effectively preventing waste and pollution caused by thermal conductive adhesive leakage and ensuring the coating quality of thermal conductive adhesive on the board material.

[0037] The control mechanism 3 drives the bidirectional screw 31 installed at the output end to rotate through the second servo motor 32. The rotating bidirectional screw 31 can effectively drive the control plates 33 screwed to the outside to move. The moving control plates 33 can effectively clamp plates of different widths to prevent position displacement during painting. The first limit rods 34 installed on both sides of the control plate 33 can effectively achieve the limit control effect.

[0038] Example 2

[0039] Reference Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment is based on the previous embodiment. A storage box 4 is fixedly installed on the surface of the frame 1. A spray nozzle 5 that penetrates the bottom wall is fixedly installed on the top surface of the storage box 4. One end of the spray nozzle 5 penetrates the top surface and the top wall of the storage box 4. One end of the collection frame 7 penetrates one side surface and one side inner wall of the frame 1 and is inserted into the other side inner wall.

[0040] Specifically, the auxiliary mechanism 6 includes a hydraulic cylinder 61. One end of the hydraulic cylinder 61 is fixedly installed on the top surface of the storage box 4. The output end of the hydraulic cylinder 61 passes through the top surface and the top wall of the storage box 4. A scraper 62 is fixedly installed on the output end of the hydraulic cylinder 61. A second limiting rod 63 is fixedly installed on the surface of the scraper 62. One end of the second limiting rod 63 is slidably connected to the top wall and the top surface of the frame 1.

[0041] Furthermore, when the internal equipment of the storage box 4 installed on the top surface of the frame 1 is activated, the thermally conductive adhesive to be applied inside the box will be discharged from the spray nozzle 5 installed on the bottom surface and penetrating the bottom wall, thereby achieving precise and efficient spraying operations. By setting a collection frame 7 below the rotating roller 21, the thermally conductive adhesive dripping from the rotating roller 21 and the sheet can be collected efficiently, avoiding waste of thermally conductive adhesive and environmental pollution.

[0042] After the auxiliary mechanism 6 is started by the hydraulic cylinder 61 installed on the top surface of the frame 1, it can accurately push the scraper 62 installed at its output end to move down smoothly. During the downward movement, the scraper 62 can scrape the surface of the plate that has been sprayed evenly, so that the thermally conductive adhesive can be more evenly attached to the surface of the plate, significantly improving the coating efficiency and quality. The second limit rods 63 installed on the surface of the scraper 62 can effectively prevent the downward movement from deviating.

[0043] Working principle: The moving mechanism 2 drives the rotating roller 21 to rotate via the first servo motor 22. The rotating roller 21 drives the rotating wheels 23 installed at the other end to rotate. The rotating wheels 23 effectively drive the outer belt 24 to rotate. The rotating belt 24 effectively drives the multiple rotating rollers 21 to rotate respectively. The rotating rollers 21 smoothly move the board material with the thermal conductive adhesive applied out, thus avoiding the board material tilting due to uneven force when directly picked up. The thermal conductive adhesive that has just been applied is very likely to leak in the tilting direction. At the same time, thanks to the synergistic effect of the rotating roller 21 and the auxiliary roller 25, even if a small amount of thermal conductive adhesive overflows, it can fall smoothly, effectively preventing waste and pollution caused by thermal conductive adhesive leakage, and ensuring the coating quality of thermal conductive adhesive on the board material.

[0044] The control mechanism 3 drives the bidirectional screw 31 installed at the output end to rotate through the second servo motor 32. The rotating bidirectional screw 31 can effectively drive the control plates 33 screwed to the outside to move. The moving control plates 33 can effectively clamp plates of different widths to prevent position displacement during painting. The first limit rods 34 installed on both sides of the control plate 33 can effectively achieve the limit control effect.

[0045] When the internal equipment of the storage box 4 installed on the top surface of the frame 1 is started, the thermal conductive adhesive to be applied in the box will be discharged from the spray nozzle 5 installed on the bottom surface and penetrating the bottom wall, thereby achieving precise and efficient spraying operation. By setting a collection frame 7 below the rotating roller 21, the thermal conductive adhesive dripping from the rotating roller 21 and the sheet can be collected efficiently, avoiding waste of thermal conductive adhesive and environmental pollution.

[0046] After the auxiliary mechanism 6 is started by the hydraulic cylinder 61 installed on the top surface of the frame 1, it can accurately push the scraper 62 installed at its output end to move down smoothly. During the downward movement, the scraper 62 can scrape the surface of the plate that has been sprayed evenly, so that the thermally conductive adhesive can be more evenly attached to the surface of the plate, significantly improving the coating efficiency and quality. The second limit rods 63 installed on the surface of the scraper 62 can effectively prevent the downward movement from deviating.
