Description
An assembly for applying adhesive to the mesh area of a folded steel sheet. Technical Field
[0001] This invention relates to the technical field of coating steel mesh, specifically to a component for applying adhesive to the mesh area of folded steel sheets. Background Technology
[0002] Foldable phone support steel sheets require mesh openings in the folding area, which is typically located in the middle of the steel sheet's length. To ensure stable and reliable folding, existing processes require filling the mesh openings with adhesive. However, due to the thinness of the folding steel sheet, existing tooling cannot guarantee reliable adhesive filling into the mesh openings or prevent adhesive overflow onto the surface of the folding steel sheet. This results in low yield and low production efficiency for filling the mesh openings. Therefore, there is an urgent need to develop a tooling suitable for adhesive treatment in the mesh openings of folding steel sheets to improve product yield and production efficiency. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides a component for applying adhesive to the mesh area of a folded steel sheet. This component allows for step-by-step application and scraping of adhesive in the mesh area, thereby improving product yield and production efficiency.

Then, adhesive is applied to the mesh area of the steel sheet using a dispensing machine. A release film is left at the bottom of the steel sheet to prevent adhesive leakage. After dispensing, the steel sheet is transferred to the second contour groove and adsorbed again. Simultaneously, a shielding cover is pressed onto the upper surface of the steel sheet, aligning the dispensed mesh area with the elongated notch. Then, the scraper of the moving scraper assembly scrapes the adhesive from the dispensed mesh area of the steel sheet along the elongated notch, removing excess adhesive and moving it to the residual adhesive area. This scraping action is repeated multiple times to ensure no residual adhesive remains on the surface. The shielding cover is then removed, and the steel sheet that has undergone adhesive filling is taken off. Finally, the adhesive on the residual adhesive area is cleaned off, and this process is repeated. This allows the adhesive in the mesh area to be dispensed and scraped in stages, improving product yield and production efficiency. Attached Figure Description

The second panel 70 has two concave regions in its central area. The lower concave region is a second concave contour groove 71, and the upper concave region is a shielding cover plate placement layer 72. The surface area of the shielding cover plate placement layer 72 is extended outwards relative to the surface area of the second concave contour groove 71. A plurality of second suction holes 73 are arranged on the surface area of the second concave contour groove 71. The second panel 70 is fixed to the upper surface of the second base plate 60 and forms a second suction cavity 74 and second suction holes 75 in the contact area. The input end of the second suction cavity 74 is located in the second concave contour groove. The second suction hole 73 is directly below the groove 71 and connected to the second suction hole 73. The second suction hole 75 protrudes to the side and is provided with a second connector 76. The output end of the second suction chamber 74 is connected to the second suction hole 75. The shielding cover plate 90 is provided with a long strip notch 91 corresponding to the mesh area of the steel sheet. The length of the long strip notch 91 is longer than the width of the corresponding area of the steel sheet. The shielding cover plate placement layer 72 is a residual glue area 77 corresponding to the part of the long strip notch 91 that is longer than the steel sheet. A movable scraper assembly 80 is installed on the upper surface of the second panel 70. The movable scraper assembly 80 performs glue application along the long strip notch 91 on the mesh area of the steel sheet that has been glued and scrapes off the residual glue and moves it to the residual glue area 77.

The scraper mounting seat 84 is fixed in the middle of the length direction of the connecting rod 83. In the working state, the scraper 85 is fixed at the position of the scraper mounting seat 84 corresponding to the position of the long notch 91, and the scraper surface 851 of the scraper 85 is located in the long notch 91.
[0037] The width of the scraper surface 851 of the scraper 82 is equal to the width of the long notch 91, which allows the scraper 85 to move back and forth to complete the scraping of glue for all the mesh holes in the mesh area.
[0038] The scraper mounting base 84 is equipped with an upper protruding handle 841 and a side protruding handle 842, which facilitates the operator to perform reasonable operations according to needs. In specific operation, the operator holds at least one of the upper protruding handle 814 and the side protruding handle 842, and then drives the scraper 851 to move back and forth along the long notch 91 through the guide rail 81 to perform scraping operations. The scraping is convenient and reliable, and the running trajectory is stable and reliable.
[0039] In practice, handles 201 are fixed on both ends of the glue scraping fixture 200 along its length, which facilitates the convenient transportation of the entire glue scraping fixture 200.
[0040] In specific implementation, the first base plate 10 and the first panel 20 have the same surface area structure. The first panel 20 and the first base plate 10 are fixed together in the thickness direction by a number of fastening screws, which makes the processing of the first suction chamber 30 and the first suction hole 40 convenient.
[0041] The second base plate 60 and the second panel 70 have the same surface area structure. The second panel 70 and the second base plate 60 are fixed together in the thickness direction by several fastening screws, which makes the processing of the second suction chamber 74 and the second suction hole 75 convenient.
[0042] The workflow is as follows: First, the steel sheet is placed on the upper surface of the first concave contour groove and reliably adsorbed after ventilation. Then, glue is applied to the mesh area of the steel sheet using a dispensing machine. A release film is left at the bottom of the steel sheet to prevent glue leakage. After the glue is applied, the steel sheet is transferred to the second contour groove and adsorbed again. At the same time, a shielding cover is pressed onto the upper surface of the steel sheet, and the mesh area of the glue application is arranged to correspond to the long notch. Then, the scraper of the moving scraper assembly scrapes the glued mesh area of the steel sheet along the long notch. The scraped excess glue is scraped off and moved to the residual glue area. The scraping action is repeated multiple times to ensure that there is no residual glue on the surface. Then, the shielding cover is removed, and the steel sheet that has been glued is removed. Finally, the glue on the residual glue area is cleaned off. This process is repeated. This allows the glue in the mesh area to be applied and scraped in stages, which improves the product yield and production efficiency.
