Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone screen production, in particular to a patch auxiliary structure for mobile phone screen production. Background Art

[0002] Mobile phone screens are also called display screens, which are used to display images and colors. The screen size is calculated based on the screen diagonal, usually in inches, which refers to the length of the screen diagonal. The screen material has become increasingly important as mobile phone color screens have become increasingly popular. The color screens of mobile phones vary due to different LCD quality and R&D technologies. There are roughly several types: TFT, TFD, UFB, STN and OLED. Generally speaking, the more colors that can be displayed, the more complex the image can be displayed, and the richer the layers of the picture. In the existing technology, when producing mobile phone screens, it is necessary to The joints of mobile phone screens are subjected to patch pressing and copper foil processing. In order to facilitate the patch pressing and copper foil processing at the joints of mobile phone screens, staff usually need to use mobile phone screen limit seats to assist staff in patch pressing and copper foil processing at the joints of mobile phone screens. Since the joints of mobile phone screens cannot be dusted and cleaned when patch pressing and copper foil processing is performed, the copper foil bonding effect may be poor and bubbles may be generated at the bonding points after patch pressing and copper foil processing, which will further affect the subsequent current and signal transmission. Therefore, a patch auxiliary structure for mobile phone screen production is proposed to address the above problems. Utility Model Content

[0024] Example 2

[0025] like Figure 1-4 As shown, in order to solve the problem that it is inconvenient to control the slider 5 to drive the cleaning brush 11 on the outside of the positioning rod 10 through the fixed shaft 9 to clean the dust on the joints of the mobile phone screen, the right end of the fixed rod 3 is fixedly connected to the motor 6, and the end of the main shaft of the motor 6 is fixedly connected to the reciprocating screw 7 that passes through the slider 5, and the reciprocating screw 7 is slidably connected to the slider 5, and the reciprocating screw 7 is rotatably connected to the fixed rod 3, and the inner rear end of the slider 5 is rotatably connected to the limiting block 8, and the limiting block 8 is slidably connected to the reciprocating screw 7, and the reciprocating screw 7 is driven to rotate by the motor 6. Under the limit of the limiting block 8, it is convenient to control the slider 5 to drive the cleaning brush 11 on the outside of the positioning rod 10 through the fixed shaft 9 to clean the dust on the joints of the mobile phone screen.

[0026] Example 3

[0027] like Figure 1-3 As shown, in order to solve the problem that it is inconvenient to automatically control the motor 6 to stop after the slider 5 moves to the left or right sides, a stop switch 12 is provided at the outer rear end of the slider 5, and the stop switch 12 is fixedly connected to the slider 5. The stop switch 12 on the left side is in contact with the fixed rod 3. By triggering the stop switch 12 after the slider 5 moves to the left or right sides, it is convenient to automatically control the motor 6 to stop after the slider 5 moves to the left or right sides.

[0028] Example 4

[0029] like Figure 4 As shown, in order to solve the problem of poor dust cleaning effect on the mobile phone screen joint during the rotation of the cleaning brush 11, the outer side of the driven gear 13 is meshed with a driving gear 14, and the driving gear 14 is rotatably connected to the slider 5 through a rotating shaft, and the top front end of the fixed rod 3 is fixedly connected with a rack 15. During the movement of the cleaning brush 11 driven by the slider 5, the driving gear 14 engages the rack 15 and engages the driven gear 13 at the same time. When the driven gear 13 drives the cleaning brush 11 on the outer side of the positioning rod 10 to rotate through the fixed shaft 9, the rotating cleaning brush 11 has a better dust cleaning effect on the mobile phone screen joint.

[0030] Example 5
