Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, and in particular to a dispensing device for the production of high thermal conductivity pads. Background Technology

[0002] High thermal conductivity pad dispensing is a technique that precisely coats highly thermally conductive materials onto the surface of electronic components using a dispensing process, primarily to improve heat dissipation performance. This process utilizes automated equipment to evenly apply the thermally conductive adhesive, ensuring close contact with the heatsink or housing, reducing thermal resistance, and enhancing heat transfer efficiency. High thermal conductivity pad dispensing is widely used in LEDs, power modules, chips, and other applications requiring efficient heat dissipation, effectively reducing operating temperatures, extending equipment lifespan, and improving stability.

[0003] However, most dispensing devices typically use a dispensing bottle to manually dispense adhesive to the center of each high thermal conductivity pad. This method is not only time-consuming and labor-intensive, but also prone to problems such as dispensing position deviation and uneven quality, thus reducing the practicality of the device.

[0004] Therefore, those skilled in the art have provided a dispensing apparatus for the production of high thermal conductivity pads to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dispensing device for producing high thermal conductivity pads. The dispensing device uses a controller to control a first servo motor to rotate a threaded rod. The rotation of the threaded rod causes a slider to slide on the upper surface of a base. When the slider reaches a predetermined position, a second servo motor mounted on a second bracket rotates a second bevel gear. This second bevel gear then rotates a first bevel gear, causing the first bidirectional threaded rod to rotate. At this point, an extension rod fitted onto the outer wall of the first bidirectional threaded rod descends to a certain height as required. An electric telescopic rod then drives the glue pump to extend and retract the worktable to a designated position. Finally, the controller controls the glue pump and completes the dispensing through the dispensing head, improving dispensing efficiency and quality, thereby enhancing the practicality of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A dispensing device for producing high thermal conductivity pads includes a moving mechanism, a fixing and clamping mechanism, and a controller. The upper end of the moving mechanism is provided with multiple fixing and clamping mechanisms. A controller is provided on one side of the moving mechanism. The moving mechanism includes a base. A first servo motor is provided at one end of the upper surface of the base. A threaded rod is fixedly connected to the output end of the first servo motor. A slider is sleeved on the outer wall of the threaded rod. A first bracket is fixedly connected to one end of the slider. A first bidirectional threaded rod is rotatably connected to the inner center of the first bracket. A first bevel gear is fixedly connected to the upper end of the first bidirectional threaded rod. A second bracket is fixedly connected to one side of the first bracket. A second servo motor is provided at the upper end of the second bracket. A second bevel gear is fixedly connected to the output end of the second servo motor. An extension rod is sleeved on the outer wall of the first bidirectional threaded rod. An electric telescopic rod is provided at one end of the extension rod. A glue pump is fixedly connected to the output end of the electric telescopic rod. A dispensing head is fixedly connected to the lower end of the glue pump.

[0008] Through the above technical solution, the dispensing device controls the first servo motor to drive the threaded rod to rotate through the controller. The rotation of the threaded rod causes the slider to slide on the upper end face of the base. When the slider slides to the specified position, the second servo motor on the second bracket drives the second bevel gear to rotate. The second bevel gear then drives the first bevel gear to rotate, which in turn causes the first bidirectional threaded rod to rotate. At this time, the extension rod sleeved on the outer wall of the first bidirectional threaded rod descends to a certain height as required. The electric telescopic rod drives the glue pump to extend and retract the worktable to the specified position. Finally, the controller controls the glue pump and completes the dispensing through the dispensing head, which improves the dispensing efficiency and quality and thus enhances the practicality of the device.

[0009] Furthermore, the fixed clamping mechanism includes a platform, with multiple workbenches fixedly connected to the upper end of the platform. A first guide plate is fixedly connected to one end of the upper surface of each of the multiple workbenches, and a second guide plate is fixedly connected to the upper end of each of the multiple first guide plates. A second bidirectional threaded rod is rotatably connected to the upper end of one side surface of each of the multiple first guide plates. A rocker arm is fixedly connected to one end of each of the multiple second bidirectional threaded rods, and sleeves are threaded to both ends of each of the multiple second bidirectional threaded rods. A support rod is rotatably connected to the lower end of each of the multiple sleeves, and a pressure plate is provided at one end of each pair of support rods.

[0010] Through the above technical solution, the dispensing device rotates the second bidirectional threaded rod by shaking the rocker arm. The rotation of the second bidirectional threaded rod causes the two sleeves to slide in opposite directions on the second guide plate. At the same time, the ends of the two support rods that are hinged to each other also move downwards due to the opposite movement. This causes the pressure plate to move downwards and press down stably along the first guide plate, so that the gasket can be clamped by the pressure plate and the subsequent dispensing work can be completed, thus improving the practicality of the device.

[0011] Furthermore, a second bevel gear is meshed with one side of the outer wall of the first bevel gear;

[0012] Through the above technical solution, this arrangement enables the rotation of the second bevel gear to drive the rotation of the first bevel gear, thereby achieving the purpose of rotating the first bidirectional threaded rod.

[0013] Furthermore, a slider is slidably connected to the upper end face of the base, and one end of the threaded rod passes through one side end face of the base and is fixedly connected to a first servo motor.

[0014] Through the above technical solution, this setting enables the threaded bar to have a stable fulcrum for rotation.

[0015] Furthermore, a platform is fixedly connected to the upper end of the base;

[0016] The above technical solution allows the slider to slide more conveniently under the platform.

[0017] Furthermore, the plurality of sleeves are slidably connected to one side of the outer wall of the second guide plate;

[0018] Through the above technical solution, this setting ensures that the sleeve will not rotate with the rotation of the second bidirectional threaded rod and will maintain stable movement.

[0019] Furthermore, the plurality of pressure plates are slidably connected to one side of the outer wall of the first guide plate, and one end of each pair of support rods is hinged to the pressure plate;

[0020] The above technical solution ensures that the pressure plate will not tilt and will maintain stable movement when clamped.

[0021] Furthermore, the rotatable connection at one end of each pair of the aforementioned support rods is damped;

[0022] Through the above technical solution, this setting makes the rotation of the support rod more stable and less prone to deviation.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model proposes a dispensing device for producing high thermal conductivity pads. The dispensing device controls a first servo motor to drive a threaded rod to rotate via a controller. The rotation of the threaded rod causes a slider to slide on the upper surface of the base. When the slider slides to a specified position, a second servo motor on a second bracket drives a second bevel gear to rotate. The second bevel gear then drives a first bevel gear to rotate, which in turn causes the first bidirectional threaded rod to rotate. At this time, the extension rod sleeved on the outer wall of the first bidirectional threaded rod descends to a certain height as required. The electric telescopic rod drives the glue pump to extend and retract the worktable to a specified position. Finally, the controller controls the glue pump and completes the dispensing through the dispensing head, improving dispensing efficiency and quality, thereby enhancing the practicality of the device.

[0025] 2. This utility model proposes a dispensing device for producing high thermal conductivity gaskets. The dispensing device rotates a second bidirectional threaded rod by shaking a rocker arm. The rotation of the second bidirectional threaded rod causes two sleeves to slide against each other on a second guide plate. At the same time, the ends of the two support rods that are hinged to each other also move downwards due to the opposite movement. This causes the pressure plate to move downwards and press down stably along the first guide plate, so that the gasket can be clamped by the pressure plate and the subsequent dispensing work can be completed, thus improving the practicality of the device.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0035] A dispensing device for producing high thermal conductivity pads includes a moving mechanism 1, a fixing and clamping mechanism 2, and a controller 3. Multiple fixing and clamping mechanisms 2 are mounted on the upper end of the moving mechanism 1, and the controller 3 is mounted on one side of the moving mechanism 1. The moving mechanism 1 includes a base 101. A first servo motor 102 is mounted on one end of the upper surface of the base 101. A threaded rod 103 is fixedly connected to the output end of the first servo motor 102. A slider 104 is sleeved on the outer wall of the threaded rod 103. A first bracket 105 is fixedly connected to one end of the slider 104. A first bidirectional threaded rod 106 is rotatably connected to the center of the first bracket 105. A first bevel gear 107 is fixedly connected to the upper end of the first bidirectional threaded rod 106. A second bracket 108 is fixedly connected to one side of the first bracket 105. A second servo motor 109 is mounted on the upper end of the second bracket 108. A second bevel gear 110 is fixedly connected to the output end of the second servo motor 109. An extension rod is sleeved on the outer wall of the first bidirectional threaded rod 106. 111. An electric telescopic rod 112 is provided at one end of the extension rod 111. The output end of the electric telescopic rod 112 is fixedly connected to a glue pump 113. The lower end of the glue pump 113 is fixedly connected to a dispensing head 114. The dispensing device controls the first servo motor 102 to drive the threaded rod 103 to rotate through the controller 3. The rotation of the threaded rod 103 drives the slider 104 to slide on the upper surface of the base 101. When the slider 104 slides to the specified position, the second servo motor 109 provided on the second bracket 108 drives the second bevel gear 110 to rotate. The second bevel gear 110 then drives the first bevel gear 107 to rotate, thereby causing the first bidirectional threaded rod 106 to rotate. At this time, the extension rod 111 sleeved on the outer wall of the first bidirectional threaded rod 106 descends to a certain height as required. The electric telescopic rod 112 drives the glue pump 113 to extend and retract the worktable 202 to the specified position. Finally, the controller 3 controls the glue pump 113 to complete the dispensing through the dispensing head 114, thereby improving the dispensing efficiency and quality and thus improving the practicality of the device.

[0036] Reference Figure 3-5The fixed clamping mechanism 2 includes a platform 201. Multiple worktables 202 are fixedly connected to the upper end of the platform 201. A first guide plate 203 is fixedly connected to one end of the upper surface of each of the multiple worktables 202. A second guide plate 204 is fixedly connected to the upper end of each of the multiple first guide plates 203. A second bidirectional threaded rod 205 is rotatably connected to the upper end of one side surface of each of the multiple first guide plates 203. A rocker arm 206 is fixedly connected to one end of each of the multiple second bidirectional threaded rods 205. Sleeves 207 are threadedly connected to both ends of each of the multiple second bidirectional threaded rods 205. The lower end of each sleeve 207... Each end is rotatably connected to a support rod 208, and a pressure plate 209 is provided at one end of every two support rods 208. The dispensing device rotates the second bidirectional threaded rod 205 by shaking the rocker arm 206. The rotation of the second bidirectional threaded rod 205 causes the two sleeves 207 to slide against each other on the second guide plate 204. At the same time, the ends of the two support rods 208 that are hinged to each other also move downwards due to the opposite movement. This causes the pressure plate 209 to move downwards as well and press down stably along the first guide plate 203, so that the gasket can be clamped by the pressure plate 209 and the subsequent dispensing work can be completed, which improves the practicality of the device.

[0037] The second bevel gear 110 is meshed with one side of the outer wall of the first bevel gear 107. This arrangement allows the rotation of the second bevel gear 110 to drive the first bevel gear 107 to rotate, thereby achieving the purpose of rotating the first bidirectional threaded rod 106.

[0038] A slider 104 is slidably connected to the upper end face of the base 101, and one end of the threaded rod 103 passes through one side end face of the base 101 and is fixedly connected to the first servo motor 102. This arrangement enables the threaded rod 103 to have a stable fulcrum for rotation.

[0039] The upper end of the base 101 is fixedly connected to the platform 201, which allows the slider 104 to slide more conveniently under the platform 201.

[0040] Multiple sleeves 207 are slidably connected to one side of the outer wall of the second guide plate 204. This arrangement ensures that the sleeves 207 do not rotate with the rotation of the second bidirectional threaded rod 205 and maintain stable movement.

[0041] Multiple pressure plates 209 are slidably connected to one side of the outer wall of the first guide plate 203, and one end of each pair of support rods 208 is hinged to the pressure plate 209. This arrangement ensures that the pressure plate 209 will not tilt when clamping and will maintain stable movement.

[0042] The rotational connection at one end of each pair of support rods 208 is damped, which makes the rotation of the support rods 208 more stable and less prone to deviation.

[0043] Working principle: The dispensing device controls the first servo motor 102 via controller 3 to drive the threaded rod 103 to rotate. The rotation of the threaded rod 103 causes the slider 104 to slide on the upper surface of the base 101. When the slider 104 slides to the specified position, the second servo motor 109 on the second bracket 108 drives the second bevel gear 110 to rotate. The second bevel gear 110 then drives the first bevel gear 107 to rotate, thereby causing the first bidirectional threaded rod 106 to rotate. At this time, the extension rod 111 sleeved on the outer wall of the first bidirectional threaded rod 106 descends to a certain height as required. The electric telescopic rod 112 carries... The adhesive pump 113 extends to the designated position of the worktable 202. Finally, the controller 3 controls the adhesive pump 113 to complete the dispensing through the dispensing head 114. The dispensing device rotates the second bidirectional threaded rod 205 by shaking the rocker arm 206. The rotation of the second bidirectional threaded rod 205 causes the two sleeves 207 to slide in opposite directions on the second guide plate 204. At the same time, the ends of the two support rods 208 that are hinged to each other also move downwards due to the opposite movement. This causes the pressure plate 209 to move downwards and press down stably along the first guide plate 203, so that the gasket can be clamped by the pressure plate 209 and complete the subsequent dispensing work.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
