Description

Technical Field

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

[0002] In the manufacturing of electronic products and packaging materials, the application of double-sided adhesive is a crucial step in product assembly. Traditional adhesive application is typically done manually, requiring operators to individually attach double-sided adhesive blocks with release paper to the surface of the product and manually press to achieve adhesion. This method has significant drawbacks: firstly, manual operation is inefficient and cannot meet the production capacity demands of modern manufacturing; secondly, the accuracy of manual positioning is greatly affected by the operator's skill level, easily leading to problems such as adhesive block misalignment and tilting, resulting in a lower product yield; and thirdly, uneven pressure during manual pressing can cause quality issues such as localized bubbling or incomplete adhesion of the adhesive.

[0003] While some semi-automated adhesive coating equipment exists in the current technology, its positioning mechanism mostly adopts a simple mechanical slot structure, which cannot effectively adapt to the positioning requirements of adhesive blocks of different sizes. At the same time, traditional equipment lacks reliable fixing devices, and the positioned adhesive blocks are prone to displacement due to mechanical vibration or operational impact during the adhesive coating process. In addition, existing equipment generally lacks an efficient demolding and separation mechanism, making manual demolding inconvenient.

[0021] The integrated lifting device enables the automatic pushing away of the product after it has been coated with adhesive. The mechanical lifting action separates the product from the positioning structure, eliminating the risk of damage to the adhesive layer caused by manual prying, while also reducing the intensity of personnel operation.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1 to 6 The diagram shows an adhesive coating auxiliary device for supporting a double-sided adhesive block 1. A release paper 2 is attached to the side of the double-sided adhesive block 1 closest to the adhesive coating auxiliary device. The adhesive coating auxiliary device includes a worktable 3. The upper surface of the worktable 3 is provided with several positioning structures 4 for positioning the double-sided adhesive block 1. The worktable 3 is also provided with a suction nozzle structure 5 for fixing the positioned double-sided adhesive block 1. The suction nozzle structure 5 is connected to a vacuum device 6 that generates negative pressure to adsorb the double-sided adhesive block 1. The worktable 3 is also provided with a lifting device 7 for pushing the product with the double-sided adhesive block 1 attached away from the positioning structures 4.

[0031] Multiple double-sided adhesive blocks 1 are attached to a release strip 21. The layout of the double-sided adhesive blocks 1 corresponds one-to-one with the position of the positioning structure 4, and the position of the positioning structure 4 corresponds one-to-one with the bonding position of the product to be coated. The adhesive force of the double-sided adhesive blocks 1 to the release paper is greater than that to the release strip. In use, the double-sided adhesive blocks 1 are aligned with the position of the positioning structure 4, the entire release strip 21 is placed on the worktable 3, the air extraction device 6 extracts air to make the suction nozzle structure 5 suck up the double-sided adhesive blocks 1, thereby peeling off the release strip. Then the product to be coated is placed on the double-sided adhesive blocks 1, so that the double-sided adhesive blocks 1 are firmly attached to the product. Finally, the product with the double-sided adhesive blocks 1 attached is pushed out by the lifting device 7.

[0032] This design, by positioning the double-sided adhesive block 1, significantly increases the amount of adhesive applied per unit time compared to traditional single-station manual operation, effectively solving the misalignment problem caused by manual operation. The synergistic effect of the suction nozzle structure 5 and the air extraction device 6 forms a negative pressure adsorption mechanism, generating a uniform vertical adsorption force on the double-sided adhesive block 1 during the adhesive application process. Compared to traditional mechanical pressing methods, this design avoids the risk of adhesive deformation under pressure and ensures stable adhesion between the release paper and the adhesive block during the adhesive application process, improving the product yield.

The air extraction chamber 51 serves as the integrated cavity of the negative pressure generator, forming a uniform negative pressure field through the sealed space inside the workbench 3. The first air extraction holes 52 can be arrayed in the contact area of ​​the double-sided adhesive block 1, so that the adsorption force is distributed on the bottom surface of the double-sided adhesive block 1. The release strip 21 is provided with a clearance through hole 210 corresponding to the position of the positioning hole 10, through which the positioning post passes.

[0034] In one embodiment, the lifting device 7 includes a lifting plate 71 disposed above the workbench 3. The lifting plate 71 has a through hole 711 corresponding to the position of the positioning post for the positioning post to pass through. The lifting plate 71 also has a second suction hole 712 corresponding to the position of the first suction hole 52 and communicating with the first suction hole 52. The lifting device 7 further includes a driving mechanism 72 for driving the lifting plate 71 to move up and down. The lifting plate 71 pushes the product away from the positioning post, making it easier to remove the glued product and avoiding scratches from the positioning post on the product or double-sided adhesive block 1 caused by manual removal. This improves product quality.

[0035] Furthermore, a sealing gasket 713 is provided between the lower surface of the lifting plate 71 and the worktable 3. The sealing gasket 713 is provided with a clearance hole 714 that connects the first air intake hole 52 and the second air intake hole 712. This improves airtightness and thus better forms negative pressure.

[0036] In one embodiment, the drive mechanism 72 includes an electrically operated telescopic rod, and the lifting plate 71 is connected to the push rod of the electrically operated telescopic rod. The adhesive coating auxiliary device also includes a base 8 located below the worktable 3, and the fixed housing of the electrically operated telescopic rod is fixedly connected to the base 8. The lifting plate 71 can be connected to the push rod via threaded fasteners or other connection methods.

[0037] In one embodiment, the fixed housing of the electric telescopic rod extends through the lower part of the worktable 3 into the suction chamber 51, and the push rod of the electric telescopic rod passes through the upper part of the worktable 3 and connects to the lifting plate 71. A sealing sleeve 721 is provided between the fixed housing of the electric telescopic rod and the lower part of the worktable 3 to seal the gap between them, and the sealing sleeve 721 is slidably connected to the fixed housing of the electric telescopic rod. This makes the overall structure of the adhesive coating auxiliary device more compact and reduces the space required.

[0038] In one embodiment, the workbench 3 is provided with a quick-release air pipe connector, and the suction end of the air extraction device 6 is connected to the quick-release air pipe connector through the air pipe 61 so as to communicate with the air extraction chamber 51.
