Description

Technical Field

[0001] The utility model relates to the technical field of gluing of tempered films, in particular to an automatic gluing machine for tempered films. Background Art

[0002] Tempered film is a mobile phone protective film. It is a high-end new product that provides the most enhanced protection for the screen. Tempered film uses chemical or physical methods to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass's own wind pressure resistance and impact resistance. It has excellent properties such as high hardness, low toughness, good wear resistance, and not easy to scratch. Tempered film needs to be coated with glue during the production process. When some tempered films are used with automatic glue coating machines, first place the tempered film in the corresponding card slot on the workbench, and then The control element is used to make the glue coating roller rotate and move longitudinally along the surface of the tempered film through the slide groove, and the glue coating operation is performed on the surface of the tempered film by utilizing the rolling contact between the glue coating roller and the tempered film. However, the glue coating roller of the device moves longitudinally along the slide groove, and the vertical distance between the glue coating roller and the tempered film is always fixed. The surface of the glue coating roller is uneven due to long-term use, and a vertical gap will appear between the glue coating roller and the tempered film, which affects the uniformity of the device's glue coating on the tempered film and needs to be improved. At the same time, during the gluing process of the tempered film, excess glue will slide along the wall and remain in the groove, affecting the subsequent gluing operation of the tempered film.

The support frame is arranged on the upper side of the glue coating platform, and a linear motor is provided at the right end of the top wall of the support frame. The input end of the linear motor is electrically connected to the output end of the single-chip microcomputer, and a glue storage box is provided at the mover end of the linear motor. A slide groove is opened on the left side of the top wall of the support frame, and the glue storage box is slidably connected to the slide groove. A hose is penetrated through the left and right walls of the glue storage box, and a hard tube is provided between the hoses. The outer side of the hard tube is rotatably connected with a uniformly distributed glue coating roller through a sealed bearing, and the inner wall of the hard tube is connected to the adjacent glue coating roller through a through groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are: the automatic glue coating machine for tempered film has the following advantages:

[0015] 1. When the tempered film is coated with glue, the single chip microcomputer starts the linear motor so that its moving end drives the glue storage box to move forward longitudinally along the slide slot, and the glue storage box indirectly drives the glue coating roller to move forward longitudinally. As the toggle seat migrates longitudinally, the arc surface of the toggle seat contacts the upper end of the corresponding limit seat, and the limit seat moves to the end away from the center of the adjacent tempered film holder through contact pressure. The telescopic end of the second telescopic column and the second spring are stretched, so that the tempered film limit part at the rear end of the tempered film holder is opened, and then the lower end of the glue coating roller contacts the upper rear end of the tempered film, and the glue coating roller moves upward under pressure. As the spring contracts, the colloid in the glue storage box is smeared to the upper side of the tempered film through the hose and the hard pipe via the glue coating roller. As the glue storage box continues to move forward, the glue coating roller rotates through contact friction to apply glue to the upper side of the tempered film. At the same time, the compression force of spring 1 makes the glue coating roller elastically squeeze and contact with the upper side of the tempered film, thereby improving the uniformity of glue coating on the upper side of the tempered film. Subsequently, the colloid on the upper side of the tempered film is scraped and leveled by the triangular scraper at the rear end, further improving the gluing effect of the device on the tempered film. The automatic glue coating machine for tempered film uses an elastic element to make the glue coating roller always elastically fit with the surface of the tempered film to avoid a glue coating gap between the two, and cooperates with the triangular scraper to effectively improve the uniformity of glue coating on the surface of the tempered film.

[0016] 2. After the device has finished gluing the upper side of the tempered film, the triangular scraper seat is used to scrape the excess colloid on the tempered film into the collection shell to avoid excess colloid remaining in the tempered film holder, thereby affecting the subsequent tempered film gluing operation. The single-chip microcomputer starts the heating plate to heat the collection shell to avoid the solidification of the tempered film glue residue collected inside. The automatic gluing machine for tempered film can automatically collect excess residual glue during the tempered film gluing process and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

The single-chip computer 2 starts the linear motor 32 to make its movable end drive the glue storage box 33 to move forward longitudinally along the slide groove. The glue storage box 33 indirectly drives the glue coating roller 35 to move forward longitudinally. As the toggle seat 36 migrates longitudinally, the arc surface of the toggle seat 36 contacts the upper end of the corresponding limit seat 7. The limit seat 7 moves toward the end away from the center of the adjacent tempered film holder 4 through the contact pressure. The telescopic end of the telescopic column 25 and the spring 26 are stretched, so that the tempered film limiting part at the rear end of the tempered film holder 4 is opened, and then the lower end of the glue coating roller 35 contacts the upper rear end of the tempered film, and the colloid in the glue storage box 33 passes through the hose The glue coating roller 35 is applied to the upper side of the tempered film through the hard tube 34.

[0024] The working principle of an automatic glue coating machine for tempered film provided by the utility model is as follows: the air pipe 9 is connected to the external vacuum pump. When coating the tempered film, the tempered film is first placed in the corresponding tempered film holder 4, and then the suction cup 8 is vacuum-adsorbed and fixed to the corresponding tempered film through the external vacuum pump, so as to improve the gluing and fixing effect of the device on the tempered film. Then, the single-chip microcomputer 2 starts the linear motor 32 so that its movable end drives the glue storage box 33 to move forward longitudinally along the slide groove, and the glue storage box 33 indirectly drives the glue coating roller 35 to move forward longitudinally. As the toggle seat 36 migrates longitudinally, the arc surface of the toggle seat 36 contacts the upper end of the corresponding limit seat 7, and the contact pressure causes the limit seat 7 to move toward the end away from the center of the adjacent tempered film holder 4, and the telescopic end of the telescopic column 2 5 and the spring 2 6 are stretched, so that the rear end tempered film limiting part of the tempered film holder 4 is opened, and then the lower end of the glue coating roller 35 contacts the upper rear end of the tempered film, and the colloid in the glue storage box 33 passes through the hose and the hard tube 34 through the glue coating roller 35 is applied to the upper side of the tempered film. As the glue storage box 33 continues to move forward, the contact friction force causes the glue coating roller 35 to rotate so as to perform glue coating on the upper side of the tempered film. At the same time, the compression force of the spring 1 38 causes the glue coating roller 35 to elastically squeeze and contact with the upper side of the tempered film, thereby improving the uniformity of the glue coating on the upper side of the tempered film by the device. Subsequently, the triangular scraping seat 37 at the rear end is used to scrape and level the colloid on the upper side of the tempered film, thereby further improving the glue coating effect of the device on the tempered film. After the upper side of the tempered film is coated with glue, the excess colloid smeared on the tempered film is scraped into the collecting shell 12 through the triangular scraper seat 37 to avoid excess colloid remaining in the tempered film holder 4, thereby affecting the subsequent tempered film coating operation.
