By sliding the wiping assembly 500 over the BM area, the glue or other contaminants remaining on the BM area are removed, the purpose of cleaning the BM area is achieved, the BM area is improved in terms of daoyin value, and the adhesion performance of the touch screen 110 is ensured.

[0041] In some embodiments, the wiping assembly 500 includes a support body 510 and a flexible wiping member 520 arranged on the support body 510, the support body 510 is connected to the sliding assembly 400, and the flexible wiping member 520 is connected to the side of the support body 510 facing the workbench 300 and is in contact with the display module 100.

[0042] The support body 510 can be a block structure of any shape, used to support the flexible wiping member 520 on the side of the sliding assembly 400 facing the workbench 300, and enable the flexible wiping member 520 to be in contact with the BM area of the touch screen 110 with appropriate pressure. The flexible wiping member 520 is made of soft material to ensure that it does not cause damage to the BM area of the touch screen 110 during wiping. The connection between the flexible wiping member 520 and the support body 510 can be adhesive fixing or other connection and fixing. The shape of the flexible wiping member 520 can also be any shape, such as rectangular or circular, and its size can be set based on the width of the BM area of the touch screen 110, so that the contact area between the flexible wiping member 520 and the BM area is larger, and the wiping effect is more uniform.

[0043] Optionally, the support body 510 can include a first block 511 and a second block 512 connected to the first block 511, the first block 511 has a first mounting surface facing the positioning surface 301 and parallel to the positioning surface 301, the second block 512 has a second mounting surface facing the positioning surface 301 and perpendicular to the positioning surface 301, and the first mounting surface and the second mounting surface are both provided with the flexible wiping member 520.

[0044] The first block 511 and the second block 512 can be block structures of any shape, and the first block 511 and the second block 512 can be integrally formed or connected and fixed by bonding, welding or fastener connection after being separately processed. The first block 511 can be located above the workbench 300, so that the horizontal side wall of the first block 511 facing downward serves as a first mounting surface. The second block 512 can be located on one side of the workbench 300, and the vertical side wall of the second block 512 facing the workbench 300 serves as a second mounting surface. The flexible wiper 520 is mounted on the first mounting surface and the second mounting surface, and the flexible wipers 520 located on the first mounting surface and the second mounting surface can be separate or an integral structure fixed to the first mounting surface and the second mounting surface by bending.

[0045] After the display module 100 is placed on the positioning surface 301, the first mounting surface and the second mounting surface correspond to the upper surface and the side surface of the BM area of the touch screen 110, and the flexible wipers 520 arranged on the first mounting surface and the second mounting surface can be attached to the two side surfaces of the BM area with appropriate pressure, so as to simultaneously wipe and clean the two side surfaces of the BM area of the touch screen 110, thereby improving the cleaning efficiency of the touch screen 110.

[0046] In some embodiments, the flexible wiper 520 is a dust-free cloth or a sponge.

[0047] The dust-free cloth is made of superfine fibers, and has a microstructure that can capture and lock small particles, thereby achieving cleaning effect. The dust-free cloth does not produce fiber debris during use, thereby ensuring the cleaning effect of the display module 100.
