[0023] This utility model proposes a surface coating device for tablet computer production.

[0025] In this embodiment, the tablet computer is placed in station 2 and station 3, and station 2 and station 3 are moved below the alcohol spraying mechanism 6. The alcohol spraying mechanism 6 sprays alcohol onto the tablet computer, and then the cleaning mechanism 7 cleans the tablet computer. At the same time, the material transfer mechanism 10 takes out the cut material sheet from the material box 5 and places it on the adjustment mechanism 4. The vision inspection mechanism 9 detects the position of the material sheet on the adjustment mechanism 4 in real time. The adjustment mechanism 4 adjusts according to the position detected by the vision inspection mechanism 9 until it is adjusted to the preset position. Then, the film application mechanism 8 transfers the adjusted material sheet to directly above station 2 or station 3, and finally applies the film. This realizes the rotating film application of tablet computers in station 2 and station 3, which improves the film application efficiency and the film application accuracy. It also eliminates the need for manual secondary adjustment of the tablet computer after film application, further improving the film application efficiency.

A second vertical plate 72 is fixedly installed on the upper end of the support frame, and the first vertical drive assembly 73 is fixedly installed on the second vertical plate 72. The scraper 74 is fixedly connected to the output end of the vertical drive assembly. When station 1 2 and station 2 3 transport the tablet computer to below the scraper 74, the first vertical drive assembly 73 drives the scraper 74 to move downwards to abut against the upper end of the tablet computer. Station 1 2 and station 2 3 continue to transport the tablet computer forward, and the scraper 74 scrapes away the alcohol and foreign objects on the tablet computer. After the film is applied, when station 1 2 and station 2 3 transport the tablet computer back to the fixed position below, the first vertical drive assembly 73 drives the scraper 74 to move downwards to abut against the tablet computer, thereby scraping and pressing the applied film to further improve the film application quality and prevent air from existing in some areas.

The fourth sliding rail 18 and the fifth sliding rail 42 control the material sheet on the support plate 45 to adjust its position in the horizontal and vertical directions. Then, the drive motor 44 controls the rotation of the support plate 45, thereby realizing the adjustment of the material sheet at any position and angle on the plane of the support plate 45, so as to adjust it to the preset position for accurate film application.

[0036] Specifically, cylinders are installed on both slider 2 41 and machine frame 1. The cylinders are fixedly installed on the upper ends of slider 2 41 and machine frame 1, respectively. Stop blocks are fixedly provided at the lower end of slider 2 41 and below slider 3 43. The output ends of the two cylinders are fixedly connected to the stop blocks, and the cylinders drive slider 2 41 and slider 3 43 to move on the fourth sliding track 18 and the fifth sliding track 42.

[0037] Optionally, the fourth sliding rail 18 and the fifth sliding rail 42 are linear guide rails, driven by a motor or cylinder, or directly driven by a motor.

The motor shaft is fixedly connected with gears, which mesh with the corresponding racks.

[0038] Preferably, such as Figure 4 As shown, the visual inspection mechanism 9 includes a support frame 4 91 and an inspection camera 94. The bottom of the support frame 4 91 is fixedly installed on the machine frame 1. The upper end of the support frame 4 91 is provided with a third vertical plate 92, which is fixed to the support frame 4 91 by bolts.

The suction claws 16 are controlled to move above the material box 5 by the third sliding rail 17, and then the suction claws 16 are controlled to suck up the material sheet downward by the telescopic cylinder 14.

[0040] Specifically, the structure of the third sliding track 17 is similar to that of the first sliding track 11, and it can also be directly driven by a motor. A rack is provided at the upper end of the third sliding track 17, and the motor is installed at the lower end of the support frame 13. A gear is fixed at the output end of the motor, and the gear and the rack mesh with each other. The motor drives the gear to rotate, thereby moving the support frame 13 on the third sliding track 17.

[0041] The first sliding rail 11, the second sliding rail 12, the third sliding rail 17, the fourth sliding rail 18, and the fifth sliding rail 42 are all connected to a driving component, which drives the corresponding mechanism to slide on its track. The driving component can be a motor or an air pump.

[0043] Optionally, both the suction plate 83 and the support plate 45 are provided with several suction holes, which are connected to an air pump. The air pump is used to draw a vacuum to adsorb and fix the material sheet, preventing the material sheet from moving.

[0044] Specifically, the working principle and usage process of this utility model are as follows: By placing the tablet computer in station 1 2 and station 2 3, station 1 2 and station 2 3 are moved to a position below the alcohol spraying mechanism 6, the alcohol spraying mechanism 6 sprays alcohol onto the tablet computer, and then the cleaning mechanism 7 cleans the tablet computer. At the same time, the material transfer mechanism 10 takes out the cut material sheet from the material box 5 and places it on the adjustment mechanism 4. The vision detection mechanism 9 detects the position of the material sheet on the adjustment mechanism 4 in real time, and the adjustment mechanism 4 adjusts according to the position detected by the vision detection mechanism 9 until it is adjusted to the preset position. Then, the film application mechanism 8 transfers the adjusted material sheet to the top of station 1 2 or station 2 3, and finally applies the film. This realizes the rotating film application of the tablet computer on station 1 2 and station 2 3, which improves the film application efficiency and has high film application accuracy. It eliminates the need for manual secondary adjustment of the tablet computer after film application, further improving the film application efficiency and reducing labor costs, as no additional manual secondary adjustment of the tablet computer is required.
