Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, specifically to a dispensing machine for thermally conductive gel. Background Technology

[0002] Currently, most dispensing machines can only perform flat dispensing and lack the function of dispensing on the sides of the workpiece. At the same time, as the high-density thermally conductive gel is continuously extruded from the glue tube, the resistance inside the tube gradually decreases. The pressure required to extrude the same amount of glue is relatively reduced. When using high-density thermally conductive gel for dot array operations, it is difficult to achieve precise control of the glue amount, resulting in inconsistent glue amounts at each point.

[0003] The prior art CN216225133U discloses a thermally conductive gel dispensing machine, including a worktable and a controller. A rotary motor is horizontally mounted on the worktable, and the output shaft of the rotary motor drives a clamp mounting plate. A clamp is detachably connected to one side of the clamp mounting plate. A mounting frame is mounted on the worktable, and a longitudinal transmission mechanism is mounted on the mounting frame. The output end of the longitudinal transmission mechanism drives a transverse transmission mechanism, and the output end of the transverse transmission mechanism drives a vertical transmission mechanism. The output end of the vertical transmission mechanism drives a dispensing cartridge mounting base, and a dispensing cartridge is detachably connected to the cartridge mounting base. A liquid level measuring device is installed inside the dispensing cartridge, and the dispensing cartridge is connected to a pressurizing device through an air pipe. This invention uses a rotary motor to drive the workpiece to rotate, thereby achieving continuous dispensing of glue to the side of the workpiece. At the same time, it monitors the glue level in the dispensing cartridge and adjusts the dispensing pressure in a timely manner, effectively avoiding insufficient or uneven dispensing.

[0004] However, in actual processing and use, the aforementioned thermal conductive gel dispensing machine cannot fix workpieces of different lengths and sizes, making it difficult to process diverse products and thus having poor practicality. Utility Model Content

[0005] The purpose of this invention is to provide a dispensing machine for thermally conductive gel, which can perform dispensing operations on workpieces of different lengths and sizes after fixation, thereby improving the practicality of the equipment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a dispensing machine for thermally conductive gel, including a dispensing machine body and a fixing mechanism;

[0007] The fixing mechanism includes a horizontal slide, a fixed clamping plate, a movable clamping plate, a guide block, a screw, a servo motor, and a positioning device. The horizontal slide is located above the worktable of the dispensing machine body. The fixed clamping plate is fixed to the right side of the horizontal slide, and the movable clamping plate is located to the left side of the horizontal slide. The guide block is integrally formed with the movable clamping plate and slidably connected to the horizontal slide, and is located on the side of the movable clamping plate closer to the horizontal slide. The screw is rotatably connected to the horizontal slide and threadedly connected to the movable clamping plate, and is located on the rear side of the horizontal slide. The servo motor is fixed to the left rear side of the horizontal slide, and its output shaft is connected to the screw through a rigid coupling. The positioning device is located at the bottom of the horizontal slide.

[0008] The dispensing machine body is provided with a vertical lead screw slide, and a dispensing head assembly is provided on the front side of the vertical lead screw slide.

[0009] The positioning device includes a linear guide rail and a linear slider. The linear guide rail is fixed on the worktable of the dispensing machine body, and there are two of them. The linear slider is slidably mounted on the linear guide rail and is detachably connected to the horizontal slide block.

[0010] The positioning device further includes a drive assembly, which is located on the right side of the dispensing machine body.

[0011] The thermally conductive gel dispensing machine also includes a protective mechanism, which includes a left shield and a right shield. The left shield is fixed on the left side of the dispensing machine body, and the right shield is fixed on the right side of the dispensing machine body.

[0012] This utility model discloses a dispensing machine for thermally conductive gel. During the dispensing process, the right end of the workpiece is first placed on the stepped part at the top of the fixed clamping plate for initial contact and positioning. Then, the servo motor is controlled to rotate the screw. With the sliding cooperation of the guide block and the horizontal slide, the moving clamping plate can move linearly and move closer to the fixed clamping plate until it finally abuts against the left end of the workpiece for fixation. Then, the servo motor stops. The servo motor is equipped with an encoder and a brake mechanism, which facilitates position control and enables clamping and fixing of workpieces of different lengths. Then, the positioning device moves the workpiece to the dispensing point. Finally, the dispensing machine body moves to perform the dispensing operation, thereby enabling the dispensing operation of workpieces of different lengths after fixation, improving the practicality of the equipment.

Detailed Implementation

[0018] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of a thermal conductive gel dispensing machine. Figure 2 This is a schematic diagram of the structure of the movable clamping plate 103. This utility model provides a dispensing machine for thermally conductive gel: it includes a dispensing machine body 100 and a fixing mechanism. The fixing mechanism includes a horizontal slide 101, a fixed clamping plate 102, a movable clamping plate 103, a guide block 104, a screw 105, a servo motor 106, and a positioning device. The positioning device includes a linear guide rail 109, a linear slider 110, and a drive assembly 111. This solution enables the dispensing of workpieces of different lengths after fixing, improving the practicality of the equipment. It is understood that the aforementioned solution can perform dispensing operations on workpieces of different lengths after fixing.

[0021] In this embodiment, the dispensing machine body 100 is used for dispensing operations, and it adopts an external CNC cabinet, with the CNC operation panel installed on the front door of the CNC cabinet.

[0022] The horizontal slide 101 is positioned above the worktable of the dispensing machine body 100. The fixed clamping plate 102 is fixed to the right side of the horizontal slide 101. The movable clamping plate 103 is positioned to the left side of the horizontal slide 101. The guide block 104 is integrally formed with the movable clamping plate 103 and is slidably connected to the horizontal slide 101, located on the side of the movable clamping plate 103 close to the horizontal slide 101. The screw 105 is rotatably connected to the horizontal slide 101 and threadedly connected to the movable clamping plate 103, located on the rear side of the horizontal slide 101. The servo motor 106 is fixed to the left rear side of the horizontal slide 101, and its output shaft is connected to the screw 105 via a rigid coupling. The positioning device is located at the bottom of the horizontal slide 101. The fixed clamping plate 102 is fixed to the horizontal slide block 101 by bolts, with the bolts countersunk upwards from the lower right. The guide block 104 is integrally formed with the moving clamping plate 103. The moving clamping plate 103 has a through screw hole on its rear side to facilitate threaded transmission with the screw 105. The horizontal slide block 101 has a rectangular sliding groove to facilitate linear sliding of the guide block 104. The screw 105 is mounted on detachable bearing seats on the horizontal slide block 101 on both sides by rotating bearings. The servo motor 106, with a brake mechanism and encoder, is fixed to the horizontal slide block 101 by bolts. Its output shaft is connected to the screw 105 through a rigid coupling. The positioning device is used to position the workpiece to the dispensing point.

[0023] Secondly, the dispensing machine body 100 is provided with a vertical lead screw slide 107, and a dispensing head assembly 108 is provided on the front side of the vertical lead screw slide 107. The vertical lead screw slide 107 is driven by a servo motor to rotate the transmission lead screw, which drives the vertical slide to move downward, so that the dispensing head assembly 108 moves downward to perform dispensing operations.

[0024] Then, two linear guide rails 109 are fixed to the worktable of the dispensing machine body 100; the linear slider 110 is slidably mounted on the linear guide rail 109 and detachably connected to the horizontal slide block 101. The linear guide rail 109 is fixed to the worktable of the dispensing machine body 100 by countersunk bolts, the linear slider 110 can slide linearly on the linear guide rail 109, and the horizontal slide block 101 is connected to the linear slider 110 by bolts.

[0025] Finally, the drive assembly 111 is located on the right side of the dispensing machine body 100. The drive assembly 111 adopts a transmission method of driving a servo motor and a transmission screw. The mating nut of the transmission screw is installed on the mounting protrusion at the bottom of the horizontal slide 101, so that when the servo motor is activated, it can drive the transmission screw to rotate, and the horizontal slide 101 can move under the cooperation of the linear guide rail 109 and the linear slider 110.

[0026] When using this invention to fix workpieces of different lengths and dimensions for glue application, thereby improving equipment usability, the glue application process begins by placing the right end of the workpiece on the top stepped portion of the fixed clamping plate 102 for initial contact and positioning. Then, the servo motor 106 is controlled to rotate the screw 105. Under the sliding cooperation of the guide block 104 and the horizontal slide block 101, the moving clamping plate 103 moves linearly towards the fixed clamping plate 102 until it finally abuts against the left end of the workpiece for fixation. Then, the servo motor... When the servo motor 106 stops moving, it is equipped with an encoder and a brake mechanism, which facilitates position control and enables clamping and fixing of workpieces of different lengths. Then, the drive assembly 111 moves, driving the horizontal slide 101 to move horizontally, thereby positioning the workpiece at the dispensing point. Finally, the vertical lead screw slide 107 on the dispensing machine body 100, in cooperation with the drive servo motor and the transmission lead screw, enables the dispensing head assembly 108 to move downward to perform dispensing operations. This allows for the fixing and dispensing of workpieces of different lengths, improving the practicality of the equipment.

Based on the first embodiment, this utility model provides a thermally conductive gel dispensing machine, which also includes a protective mechanism, comprising a left protective cover 201 and a right protective cover 202.

[0029] The left protective cover 201 is fixed to the left side of the dispensing machine body 100; the right protective cover 202 is fixed to the right side of the dispensing machine body 100. The left protective cover 201 is fixed to the machine base of the dispensing machine body 100 by bolts, and the right protective cover 202 is fixed to the machine base of the dispensing machine body 100 by bolts.
