Technical Field

[0001] This invention relates to the field of liquid crystal module assembly clamping technology, and in particular to a clamping device for the production of liquid crystal display modules. Background Technology

[0002] Simply put, an LCD module is a screen plus a backlight assembly. The display component of an LCD TV is the LCD module, which is equivalent to the picture tube in a CRT TV. Other parts include power supply circuits, signal processing circuits, etc. Currently, LCD modules are fixed in a frame-like structure after production, which facilitates their transfer to the next production process. However, the frame-like structure contains a lot of gaps, which can cause the LCD module to be damaged when it comes into contact with other objects during transfer, thus increasing production losses. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems and shortcomings by proposing a clamping device for the production of liquid crystal display modules. This device utilizes a pulley at one end of a transmission screw to drive another transmission screw via a belt. Adjusting the gap between the clamping plate and the fixing plate, and then rotating the transmission screw again, causes the clamping plate and the limiting strip to move closer to the fixing plate, thus clamping the planar liquid crystal module. This facilitates the clamping and fixing of the liquid crystal module, improves its safety, reduces production losses, and solves the problem of traditional methods being easily damaged.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A clamping device for producing liquid crystal display modules includes a base plate, a protective shell installed on the top outer wall of the base plate, and limit rods installed at both ends of the bottom outer wall of one end of the protective shell. A ventilation component is installed on one side outer wall of the protective shell, and a driving groove is formed at the center of the top outer wall of the base plate. A driving screw is rotatably connected in the driving groove. Sliding strips are installed on both sides of the driving screw on the top outer wall of the base plate, and a connecting plate is screwed to the outer wall of the driving screw. A clamping structure is installed on the top outer wall of the connecting plate.

[0005] Preferably, a drive motor is installed at the center of one outer wall of the base plate, and the output shaft of the drive motor is connected to one end of the drive screw. The connecting plate has a sliding groove at the sliding strip, and the connecting plate is slidably connected to the top outer wall of the base plate and the outer wall of the sliding strip.

[0006] Preferably, the clamping structure includes a fixed plate, a transmission groove formed on one side of the outer wall of the fixed plate, a transmission screw rotatably connected to the center of both ends of the transmission groove, a clamping plate screwed to the outer wall of the transmission screw, and a pulley sleeved on the transmission screw at one end of the transmission groove.

[0007] Preferably, the pulleys are connected by a belt, and guide rods are welded to the four corners of the outer wall of the clamping plate near the fixing plate. Limiting strips are installed at both ends of the outer wall of the clamping plate near the fixing plate, and the fixing plate is provided with matching holes at the guide rods and limiting strips. According to the above scheme: by using a pulley at one end of the transmission screw to drive another transmission screw with a belt, the gap between the clamping plate and the fixed plate is adjusted. After rotating the transmission screw again, the clamping plate and the limiting strip are driven closer to the fixed plate to clamp the flat LCD module, which facilitates clamping and fixing the LCD module, improves the safety of the LCD module, and reduces production losses.

[0008] Preferably, protective pads are adhered to the outer walls of the clamping plate, fixing plate, and limiting strip on the side that are close to each other, and the fixing plate has an "L" shaped cross-section. Shock absorbers are installed at the four corners of the bottom outer wall of the base plate, and casters are installed at the other end of the shock absorbers.

[0009] Preferably, the ventilation assembly includes a ventilation box installed on the outer wall of one side of the protective shell, a ventilation fan installed on the inner wall of the ventilation box, and filter material fixed to the inner wall of the ventilation box, and an air inlet is provided on the outer wall of one end of the ventilation box.

[0010] Preferably, one end of the ventilation fan is connected to the inside of the protective shell, and a sealing plate is slidably connected between the protective shell and the limiting strip, and an exhaust pipe is connected in the sealing plate, a filter screen is installed in the exhaust pipe, and a handle is installed on the top outer wall of the sealing plate. According to the above solution: after the sealing plate is reinserted, the LCD module is further protected. After the ventilation fan in the ventilation box is started, the outside air is drawn in, filtered through the filter material, and delivered to the inner wall of the protective shell, which facilitates ventilation inside the protective shell and prevents foreign objects from entering the interior during ventilation, thereby further improving safety.

[0011] Preferably, the ventilation fan and the drive motor are connected to a switch via wires, and the switch is connected to a power source via wires.

[0012] The beneficial effects of this invention are as follows: 1. By using the pulley at one end of the transmission screw to drive the other transmission screw with a belt, the gap between the clamping plate and the fixed plate is adjusted. After rotating the transmission screw again, the clamping plate and the limiting strip are driven closer to the fixed plate to clamp the flat LCD module, which facilitates clamping and fixing the LCD module, improves the safety of the LCD module, and reduces production losses. 2. After the sealing plate is reinserted, the LCD module is further protected. After the ventilation fan in the ventilation box is started, the outside air is drawn in, filtered through the filter material, and delivered to the inner wall of the protective shell. This facilitates ventilation inside the protective shell and prevents foreign objects from entering the interior during ventilation, thereby further improving safety. Attached Figure Description
