Description

Technical Field

[0001] This utility model relates to the field of thermal conductive adhesive production technology, and in particular to an automatic feeding device for thermal conductive adhesive production. Background Technology

[0002] Thermally conductive adhesives are key materials used in electronic devices to transfer heat and reduce component temperatures. They combine adhesive and thermal conductivity properties and are widely used in heat dissipation for chips, power supplies, and other devices. Their production primarily uses a base adhesive, commonly silicone or polyurethane, combined with thermally conductive fillers such as alumina and boron nitride to improve thermal conductivity. Curing agents and coupling agents are added to optimize performance. Before loading, the fillers need to be dried and ground for pretreatment. Then, using precise metering equipment, the base adhesive, fillers, and additives are gradually added to the mixing equipment according to the formula ratio to ensure uniform dispersion of the raw materials and guarantee the thermal stability of the product.

[0003] When using existing thermally conductive adhesive feeding devices, the raw materials often contain viscous fillers and have varying flowability, making them prone to residue on the feeding pipes, material bins, and conveying components. This not only causes the amount of material fed each time to deviate from the preset formula, resulting in fluctuations in the product's thermal conductivity, but also leads to the long-term accumulation of residual raw materials on the inner wall of the feeding bin, valves, and conveying channels, gradually forming stubborn deposits. This can cause malfunctions such as pipe blockage and transmission component jamming, reducing the stability and service life of the device, increasing maintenance difficulty, and making it difficult to meet the high precision and high efficiency requirements of large-scale production.

[0004] Therefore, it is necessary to invent an automatic feeding device for thermally conductive adhesive production to solve the above problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see the appendix Figure 1 - Appendix Figure 4 An automatic feeding device for thermal conductive adhesive production includes a feeding box 1, a feeding box 12 fixedly connected to one side of the bottom of the feeding box 1, mounting plates 13 fixedly connected to both sides of the feeding box 12, a side cover plate 11 fixedly connected to the side of the feeding box 1 near the feeding box 12, a movable plate 4 slidably connected to the inner side of the feeding box 1, a sealing gasket 42 fixedly connected to the top of the movable plate 4, side rods 41 fixedly connected to both sides of the movable plate 4, and a top plate 43 provided at the bottom of the movable plate 4. A brush 44 is provided at the bottom end of the top plate 43, a scraper 47 is fixedly connected to the rear end of the top plate 43, a T-shaped block 45 is fixedly connected to the top end of the top plate 43, the T-shaped block 45 is slidably connected to the inner side of the movable plate 4, a fastening bolt 46 is provided on the side of the movable plate 4, and the T-shaped block 45 is fixedly connected to the inner side of the movable plate 4 by the fastening bolt 46.

[0017] Specifically, the T-block 45 is a fixed component at the top of the top plate 43. It is slidably assembled in the pre-set groove inside the moving plate 4. The fastening bolt 46 is inserted into the side of the moving plate 4 and abuts against the T-block 45 to achieve a detachable fixed connection between the top plate 43 and the moving plate 4. This facilitates the subsequent replacement of the top plate 43, brush 44, or scraper 47. The brush 44 is fixed to the bottom of the top plate 43, and its bristles can fit against the bottom of the inner side of the feeding box 1. The scraper 47 is fixed to the rear end of the top plate 43, and its end face can fit against the rear wall of the inner side of the feeding box 1. When the moving plate 4 moves, it can drive the brush 44 to clean the residual raw materials at the bottom of the feeding box 1, and at the same time drive the scraper 47 to push the raw materials towards the downward feed trough 18. The sealing gasket 42 is fixed to the top of the moving plate 4, and its top end can fit against the top of the inner side of the feeding box 1 to prevent the raw materials from leaking out from the gap between the moving plate 4 and the top of the feeding box 1, thus ensuring the integrity of the raw material conveying.

[0018] Please see the appendix Figure 1 A side plate 14 is fixedly connected to one side of the feeding box 1, and a drive motor 3 is fixedly connected to one side of the side plate 14. Hollow tubes 15 are fixedly connected to both sides of the feeding box 1.

[0019] Specifically, the side plate 14 is vertically fixed to the side wall of the feeding box 1 away from the unloading box 12, and the drive motor 3 is fixed to the side plate 14 away from the feeding box 1. The side plate 14 can provide stable support for the drive motor 3 and prevent the drive motor 3 from shifting due to vibration during operation. Two hollow tubes 15 are symmetrically fixed to the left and right side walls of the feeding box 1, and the axis of the hollow tube 15 is consistent with the length direction of the feeding box 1. At the same time, the inner side of the hollow tube 15 is connected to the through groove 16 on the inner side of the feeding box 1, providing a suitable space for the subsequent installation of the lead screw 31 and guide rod 17, ensuring that the transmission components can accurately cooperate with the side rod 41 of the moving plate 4.

[0020] Please see the appendix Figure 2 A lead screw 31 is rotatably installed on the inner side of one hollow tube 15, and the lead screw 31 is connected to the drive motor 3. A guide rod 17 is installed on the inner side of the other hollow tube 15.

[0021] Specifically, the two ends of the lead screw 31 are rotatably connected to the inside of the hollow tube 15 near the drive motor 3 via bearings, and one end of the lead screw 31 passes through the end of the hollow tube 15 and is connected to the output shaft of the drive motor 3 via a coupling. After the drive motor 3 starts, it can drive the lead screw 31 to rotate stably inside the hollow tube 15. The two ends of the guide rod 17 are respectively fixed to the two ends of the hollow tube 15 away from the drive motor 3. The axis of the guide rod 17 is parallel to the axis of the lead screw 31. The guide rod 17 and the lead screw 31 correspond to the side rods 41 on both sides of the moving plate 4, providing a guiding foundation for the movement of the side rods 41 and preventing the moving plate 4 from deviating when it moves.

[0022] Please see the appendix Figure 4The lead screw 31 is threadedly connected to one end of the side rod 41, and the guide rod 17 is slidably connected to the other end of the side rod 41.

[0023] Specifically, the end of the side rod 41 near the lead screw 31 is provided with an internal threaded hole that matches the external thread of the lead screw 31. The lead screw 31 passes through the internal threaded hole to achieve a threaded connection with the side rod 41. The end of the side rod 41 near the guide rod 17 is provided with a smooth through hole. The guide rod 17 passes through the through hole to achieve a sliding connection with the side rod 41. When the drive motor 3 drives the lead screw 31 to rotate forward or reverse, the threaded side rod 41 will move along the axial direction of the lead screw 31. At the same time, the side rod 41 on the other side slides synchronously along the guide rod 17. The two work together to drive the moving plate 4 to move smoothly in a straight line inside the feeding box 1, ensuring the uniformity and stability of the raw material conveying.

[0024] Please see the appendix Figure 2 Both ends of the inner side of the feeding box 1 are provided with through grooves 16, which extend to the inner side of the hollow tube 15. The side rod 41 is slidably connected to the inner side of the through groove 16. The top of the unloading box 12 is provided with a unloading groove 18, which is connected to the feeding box 1.

[0025] Specifically, the through groove 16 is a long strip-shaped groove, symmetrically opened on the inner sidewalls of the left and right sides of the feeding box 1, and the two ends of the through groove 16 extend to the inner side of the hollow tube 15 respectively. One end of the side rod 41 extends out from both sides of the moving plate 4, passes through the through groove 16 and is connected to the lead screw 31 and guide rod 17 in the hollow tube 15 respectively. The through groove 16 can restrict the movement trajectory of the side rod 41, ensuring that the side rod 41 moves only along the length direction of the feeding box 1. The discharge groove 18 is opened on the top side of the discharge box 12 near the feeding box 1, and the top of the discharge groove 18 is connected to the inner bottom of the feeding box 1. The raw materials in the feeding box 1 can enter the discharge box 12 through the discharge groove 18 under the push of the scraper 47, and then be transported to the subsequent production equipment by the discharge box 12, so as to realize the orderly feeding of raw materials.

[0026] Please see the appendix Figure 1 and Figure 4 The top of the feeding box 1 is fixedly connected to a hopper 2. Slots 21 are provided at the four corners of the hopper 2. A frame 22 is provided on the inner side of the hopper 2. A filter screen 24 is provided at the bottom of the inner side of the frame 22. Inserts 23 are fixedly connected at the four corners of the frame 22. The inserts 23 are correspondingly set with the slots 21 and are slidably connected to the inner side of the slots 21.

[0027] Specifically, the bottom of the hopper 2 is fixed to the top center of the feeding box 1, and the inner side of the hopper 2 is connected to the inner side of the feeding box 1. The raw material can be poured in through the top opening of the hopper 2. The funnel-shaped structure of the hopper 2 can guide the raw material into the feeding box 1 in a concentrated manner, preventing the raw material from spilling to the outside. The insert 23 is vertically fixed to the four outer corners of the frame 22, and the slot 21 is correspondingly opened on the inner side of the four corners of the top of the hopper 2. The insert 23 can be slid in along the inner side of the slot 21 to realize the detachable snap-fit ​​connection between the frame 22 and the hopper 2. The filter screen 24 is fixed to the bottom inner side of the frame 22. When the raw material is poured in, it will first be filtered by the filter screen 24 to intercept large particles of impurities in the raw material, preventing impurities from entering the feeding box 1 and affecting subsequent production. At the same time, the cooperation between the insert 23 and the slot 21 makes it easy to disassemble the frame 22 so as to clean or replace the filter screen 24.

[0028] The working principle of this utility model is as follows: In specific use, the four corner blocks 23 of the frame 22 are slidably engaged with the four corner slots 21 of the hopper 2 to fix the frame 22 inside the hopper 2. At this time, the filter screen 24 at the bottom of the frame 22 is on the communication path between the hopper 2 and the feeding box 1. The operator pours the pre-treated thermal conductive adhesive raw material from the top of the hopper 2. After the raw material is filtered by the filter screen 24, large particles of impurities are intercepted above the filter screen 24, and the raw material that meets the requirements falls into the bottom of the inner side of the feeding box 1 through the hopper 2, which is ready for subsequent feeding and avoids impurities from entering the production process and affecting product quality. Start the drive motor 3 fixed on the side plate 14. The output shaft of the drive motor 3 drives the lead screw 31 in the hollow tube 15 on one side to rotate through the coupling. Since the lead screw 31 is threadedly connected to the side rod 41 on one side of the moving plate 4, and the side rod 41 on the other side of the moving plate 4 is slidably connected to the guide rod 17 in the hollow tube 15 on the other side, the rotation of the lead screw 31 will be converted into the axial movement of the side rod 41. The threaded side rod 41 moves along the lead screw 31, and the slidably connected side rod 41 is synchronously guided along the guide rod 17. The side rods 41 on both sides together drive the moving plate 4 to move smoothly along the through groove 16 inside the feeding box 1. During the movement of the moving plate 4, the sealing gasket 42 at its top always fits against the inner top of the feeding box 1 to prevent raw materials from leaking out from the gap between the moving plate 4 and the top of the feeding box 1. At the same time, the top plate 43, which is fixed at the bottom of the moving plate 4 by the T-block 45 and the fastening bolt 46, moves synchronously. The brush 44 at the bottom of the top plate 43 fits against the inner bottom of the feeding box 1 to clean the raw materials remaining at the bottom of the feeding box 1. The scraper 47 at the rear end of the top plate 43 fits against the inner rear wall of the feeding box 1 to continuously push the raw materials in the feeding box 1 forward, ensuring that the raw materials gather towards the discharge trough 18 at the top of the lower feeding box 12. The raw material pushed by the scraper 47 enters the feeding box 12 through the feeding chute 18, and is then transported by the feeding box 12 to subsequent mixing and other production equipment to complete one automatic feeding cycle. When the raw material is transported, the drive motor 3 is reversed, and the lead screw 31 drives the side rod 41 and the moving plate 4 to reset in the direction away from the feeding box 12, waiting for the next feeding and feeding cycle. In addition, the side cover plate 11 on one side of the feeding box 1 can be removed at any time to facilitate maintenance of the inside of the feeding box 1. The mounting plates 13 on both sides of the feeding box 12 are used to fix the entire device next to the production equipment to ensure the stability of the device during operation.

[0029] 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 embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
