Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and in particular to a vacuum device for adhesive coating. Background Technology

[0002] Adhesive coating is a technique that involves uniformly covering the surface of a material with a liquid or semi-solid adhesive. After the adhesive cures, it forms an adhesive or sealing layer. Applying adhesive in a vacuum environment can shorten the curing time and enhance the reliability of the seal.

[0003] A Chinese patent with publication number CN210995094U discloses a device for avoiding air bubbles in thermally conductive adhesive. The key technical points are: it includes a sealed container and a vacuum device. The sealed container covers the product coated with the adhesive, and the vacuum device evacuates the sealed container. Before installing electronic or electrical components on a circuit board, a thermally conductive adhesive is first applied to the corresponding area of ​​the circuit board. Then, the sealed container covers the board coated with the adhesive, sealing the board. The vacuum device then evacuates the sealed container, removing air from the thermally conductive adhesive. After removing the sealed container from the circuit board, the corresponding electronic or electrical components are installed on the area of ​​the board coated with the adhesive. This effectively improves the thermal conductivity of the thermally conductive adhesive.

[0029] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a vacuum device for applying adhesive, including a frame 1, a vacuum hood 3 and a lifting plate 2 mounted on the surface of the frame 1, a gear 5 rotatably connected to the surface of the lifting plate 2, a first toothed plate 8 slidably connected to the side of the lifting plate 2 near the gear 5, and a second toothed plate 9 mounted on the side of the lifting plate 2 near the first toothed plate 8. Both the first toothed plate 8 and the second toothed plate 9 mesh with the gear 5. A first clamping plate 11 is fixedly connected to the side of the first toothed plate 8, and a second clamping plate 12 is fixedly connected to the side of the second toothed plate 9 near the first clamping plate 11. The movement of the first toothed plate 8 and the second toothed plate 9 can be controlled by the gear 5, and the position of the product placed on the lifting plate 2 can be restricted by the first clamping plate 11 and the second clamping plate 12.

[0030] The following is a detailed explanation of its overall setup and function.

[0031] Reference Figures 1-4 As shown in this embodiment: Rubber pads 13 are glued to the sides of the first clamping plate 11 and the second clamping plate 12 that are close to each other. Several grooves 14 are formed on the surface of the rubber pads 13. The rubber pads 13 and the grooves 14 on them improve the effect of the first clamping plate 11 and the second clamping plate 12 in restricting the product position. Two limiting plates 10 are fixedly connected to the side of the lifting plate 2 near the first toothed plate 8. Both limiting plates 10 are sleeved on the surfaces of the first toothed plate 8 and the second toothed plate 9. The limiting plates 10 ensure that the first toothed plate 8 and the second toothed plate 9 can move while restricting their position. A fixing rod 4 is fixedly connected to the side of the lifting plate 2 near the gear 5. The fixing rod 4 is rotatably connected to the inner wall of the gear 5. A mounting plate 6 is fixedly connected to the other end of the fixing rod 4. A torsion spring 7 is sleeved on the surface of the fixing rod 4, and both ends of the torsion spring 7 are fixedly connected to the mounting plate 6 and the gear 5, respectively. The torsion spring 7 and gear 5 can be connected by the fixed rod 4 and the mounting plate 6. The rotation of gear 5 can be controlled by the fixed rod 4, the mounting plate 6 and the torsion spring 7.

[0032] A positioning plate 15 is fixedly connected to the upper surface of the lifting plate 2, and a stop plate 17 is slidably connected to the side of the lifting plate 2 near the positioning plate 15. The positioning plate 15 and the stop plate 17 restrict the position of the product placed on the lifting plate 2. An arc-shaped plate 18 is fixedly connected to the side of the stop plate 17 away from the positioning plate 15, and an adjusting screw 19 is threaded into the inner wall of the arc-shaped plate 18. When it is necessary to fix the position of the stop plate 17, the position of the adjusting screw 19 can be adjusted to restrict the movement of the stop plate 17. A connecting plate 20 is fixedly connected to the end of the adjusting screw 19 near the lifting plate 2, and a pad 21 made of rubber is fixedly connected to the side of the connecting plate 20 away from the adjusting screw 19. A groove is formed on the side of the lifting plate 2 near the stop plate 17, and a slider 16 is slidably connected to the surface of the groove on the lifting plate 2. The slider 16 is fixedly connected to the stop plate 17. The connecting plate 20 can be used to connect the adjusting screw 19 and the pad 21. The connecting plate 20 and the pad 21 can improve the effect of the adjusting screw 19 on the position restriction of the abutment 17.

[0033] Working principle: When product processing is required, the first toothed plate 8 is moved by the first clamping plate 11, causing it to slide on the inner wall of the limiting plate 10. The movement of the first toothed plate 8 drives the gear 5 to rotate, thereby controlling the second toothed plate 9 and the second clamping plate 12 to move synchronously. Then, the product to be processed is placed on the surface of the lifting plate 2 of the frame 1, bringing the product close to the positioning plate 15. The first clamping plate 11 is released, and under the action of the torsion spring 7, the gear 5 rotates, thereby controlling the first clamping plate 11 and the second clamping plate 12 to move closer to the product. The moving abutment plate 17 drives the slider 16 on the lifting plate 2. The upper slide surface slides closer to the product. The adjusting screw 19 is rotated to rotate on the inner wall of the arc plate 18, controlling the connecting plate 20 and the pad 21 to move closer to the lifting plate 2, thus restricting the position of the abutment plate 17. Then, the lifting plate 2 and the vacuum hood 3 are moved so that the vacuum hood 3 seals the product on the lifting plate 2. Finally, the vacuum hood 3 is evacuated. The fixed rod 4 and the mounting plate 6 allow the torsion spring 7 to control the rotation of the gear 5. The rubber pad 13 and the groove 14 improve the effect of restricting the product position. The first clamping plate 11, the second clamping plate 12, the positioning plate 15, and the abutment plate 17 can restrict the position of the product placed on the surface of the lifting plate 2, so as to avoid the product shaking caused by the movement of the lifting plate 2 and thus avoid the product being damaged by collision. The gear 5, the first rack, the second rack, the fixing rod 4, the mounting plate 6, and the torsion spring 7 can adjust the distance between the first clamping plate 11 and the second clamping plate 12, so as to adapt to the processing of products of different sizes.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
