Description

Technical Field

[0001] The present application belongs to the field of automation, and in particular relates to a double-sided cleaning device for a display panel. Background Art

[0002] During the production process of glass display panels, it is necessary to ensure dust-free operation in the production workshop to prevent dust from entering and affecting the production qualification rate of subsequent products.

[0003] Since the conveyor roller is in operation for a long time, the static electricity carried on its surface will absorb some fine dust, human hair, skin debris, etc., which may stick to the display panel during the transmission process, affecting subsequent processing and causing a decrease in product qualification rate. Therefore, the display panel needs to be cleaned.

[0004] In the prior art, the display panel is usually cleaned manually using a vacuum cleaner or a tape roller, and then manually or by adding a process to flip the display panel over and clean it again. This method has a low cleaning efficiency and greatly affects production efficiency.

[0005] Therefore, there is a need for an efficient double-sided cleaning mechanism for a display panel that can solve the above problems. Summary of the invention

[0006] In order to solve the deficiencies of the prior art, the present application provides a double-sided cleaning device for a display panel, which can automatically clean the display panel to facilitate subsequent production.

[0009] Through this solution, when the conveyor roller conveys the display panel, the cleaning tape on the device is always attached to the display panel and picks up fine dust as the display panel is conveyed; the winding roller group is set to roll up the used tape to prevent the tape with dust particles from contacting the display panel and sticking the dust back to the roller, thereby completing the automatic cleaning of the upper and lower surfaces of the display panel without manual turning over, greatly improving the cleaning efficiency.

[0013] Preferably, the cleaning mechanism located below comprises a supporting roller group, the supporting roller group is located in the cleaning area, and the cleaning tape is wound over the supporting roller group to clean the display panel.

[0014] Through this solution, the support roller group can support the display panel from the bottom, reduce the bending caused by its own gravity, and ensure the cleaning effect of the cleaning mechanism above.

[0015] Preferably, an adjustment frame arranged perpendicular to the conveying roller is provided on the mounting frame, and the cleaning mechanism is slidably connected to the adjustment frame via a vertical movement mechanism, and the vertical movement mechanism is used to drive the cleaning mechanism to approach or move away from the display panel.

[0016] Through this solution, the vertical movement mechanism can drive the cleaning mechanism to lift and fall, so that it can be lifted and passed through the area that does not need to be cleaned, such as the disconnection point of the display panel, to avoid the cleaning tape and the edge of the display panel being cut.

[0017] Preferably, the cleaning mechanism comprises two mounting plates arranged in parallel, the winding roller group is installed between the mounting plates, an adjusting column is provided on the mounting plates, and the driving electric cylinder in the vertical movement mechanism drives the cleaning mechanism by driving the adjusting column.

[0018] Through this solution, the electric cylinder is driven to push the adjustment column to drive the cleaning mechanism. The electric cylinder can control the driving distance and force, thereby improving the application range of the device.

[0019] Preferably, the winding roller group located on the upper cleaning mechanism includes an installation roller, a storage roller and a pressure roller, wherein the installation roller is used to install the cleaning tape, the storage roller is used to rotate under the drive of the winding motor to store the used cleaning tape, and the pressure roller is used to press the cleaning tape onto the display panel.

[0020] Through this solution, the use of a pressure roller can ensure better contact between the cleaning tape and the display panel, improve the cleaning effect, and avoid curling of the cleaning tape and other factors that affect the cleaning effect.

[0021] Preferably, there are several pressure rollers arranged side by side, and the cleaning tape is laid to the bottom of the pressure roller; the pressure roller is rotatably mounted on a pressure frame, and the pressure frame is elastically connected to the mounting plate through a buffer spring.

[0022] Through this solution, the cleaning tape is ensured to have a longer distance for cleaning the display panel, increasing the contact area and thus improving reliability. The buffer spring can make the pressure frame move up and down a certain distance to avoid rigid collision with the display panel, further adapt to the height difference, and improve the adaptability of the device.

[0023] Preferably, the winding roller group on the cleaning mechanism below includes a mounting roller, a receiving roller and the supporting roller group, the mounting roller is used to mount the cleaning tape, and the receiving roller is used to rotate under the drive of the winding motor to receive the used cleaning tape.

[0024] Through this solution, the lower surface can be cleaned by using the gravity of the display panel itself to press it onto the cleaning tape.

[0025] According to one embodiment of the present application, the beneficial effect of using the double-sided cleaning device of the display panel is that the display panel can be cleaned by directly placing the device on the conveyor roller without the need for manual intervention, without the need to set up additional workstations, saving time and labor and greatly improving cleaning efficiency.
