[0002] Screen printing equipment is required for screen printing on mobile phone cover glass. The mobile phone cover glass is conveyed or manually filled into the designated position for screen printing.

[0003] In the prior art, such as the Chinese authorized patent CN202123122816.6, a high-definition screen printing device for mobile phone cover glass, a metal ring rotates a bidirectional screw, causing two second threaded sleeves to move towards each other along the bidirectional screw, driving the right-angled trapezoidal abutments. This allows the inclined surfaces of the two abutments to clamp the screen printing plate inserted into the rectangular sleeve. The rectangular support frame plate welded on the rectangular sleeve can support the screen printing plate, increasing the stability and levelness of the screen printing plate on the rectangular sleeve. This has the advantage of facilitating the installation and disassembly of the screen printing plate, and is beneficial for the later disassembly and cleaning of the screen printing plate.

[0004] However, the loading and unloading of materials requires manual loading, which is slow and requires stopping the equipment during the loading process, affecting production efficiency. Utility Model Content

A bracket is disposed on the outer side of the conveyor belt, and a first drive motor is disposed at one upper end of the bracket. The output end of the first drive motor is connected to a screen printing mechanism through a first transmission lead screw. A pressing member is disposed at the lower part of the bracket.

[0008] Furthermore, the conveyor belt consists of two conveyor rollers, one end of which is connected to the output end of the second drive motor, and two conveyor tracks are respectively fitted onto both ends of the two conveyor rollers, with several positioning blocks provided on each of the two conveyor tracks.

[0009] Furthermore, one end of the loading plate has two assembly slots that are adapted to the positioning block, and a detection tag is provided between the two assembly slots.

[0010] Furthermore, an infrared detection head adapted to the detection label is provided on the inner wall of the bracket.

[0011] Furthermore, the screen printing mechanism includes a slider threadedly connected to the first transmission screw. The lower end of the slider is connected to an assembly frame via a first electric telescopic rod. A third drive motor is mounted on one end of the assembly frame. The output end of the third drive motor is connected to a sliding frame via a second transmission screw. A brush wheel is mounted on the lower part of the sliding frame.

[0012] Furthermore, a screen printing mesh is provided at the lower part of the assembly frame.

[0013] Furthermore, the top-pressing component includes a second electric telescopic rod and a support plate installed at the output end of the second electric telescopic rod.

[0014] Furthermore, an operation panel is installed on one outer wall of the bracket.

[0015] Furthermore, a top block is provided at the lower part of the loading plate.

[0016] Furthermore, a top platform is provided between one end of the two conveyor belts for cooperating with the top block to lift them up.

[0017] The beneficial technical effects of this utility model are as follows: According to the high-definition screen printing device for mobile phone cover glass of this utility model, mobile phone cover glass is pre-loaded onto a loading plate. Then, the loading plate is transported one by one to a designated position via a conveyor belt and positioning blocks. Utilizing the cooperation of an infrared detector and a detection tag, a delay is performed when the detection tag reaches the detection point and is detected by the infrared detector. The delay time is set according to the actual screen printing working time, allowing the loading plate to stop after reaching the designated position and cooperate with the screen printing mechanism for screen printing operations. After the delay, the transport continues, and the operation is repeated when the next loading plate reaches the designated position, thus effectively improving work efficiency. Simultaneously, during the screen printing operation, the mobile phone cover glass is loaded into the loading plate and then placed onto the conveyor belt, effectively reducing the time wasted in loading the mobile phone cover glass.

The output end of the third drive motor 10 is connected to a sliding frame 12 via a second transmission screw. A brush wheel 19 is mounted on the lower part of the sliding frame 12. A screen printing screen 11 is provided on the lower part of the assembly frame 15 for screen printing operations. The top pressure component 7 includes a second electric telescopic rod and a support plate mounted on the output end of the second electric telescopic rod for supporting from the bottom during screen printing operations. An operation panel 6 is mounted on one outer wall of the support 1.

[0030] In summary, in this embodiment, the high-definition screen printing device for mobile phone cover glass pre-loads mobile phone cover glass onto the loading plate 3. Then, the conveyor belt, in conjunction with positioning blocks, allows the loading plate 3 to be transported one by one to a designated position. Utilizing the cooperation of the infrared detector 18 and the detection tag 16, a delay is performed when the detection tag 16 reaches the detection point and is detected by the infrared detector 18. The delay time is set according to the actual screen printing working time, allowing the loading plate 3 to stop after reaching the designated position and cooperate with the screen printing mechanism 4 for screen printing operations. After the delay, the transport continues, and the operation repeats when the next loading plate 3 reaches the designated position. This effectively improves work efficiency. Simultaneously, during the screen printing operation, the mobile phone cover glass is loaded into the loading plate 3 and then placed onto the conveyor belt 2, effectively reducing the time wasted in loading the mobile phone cover glass.
