Description

Technical Field

[0001] The present application relates to the technical field of liquid crystal panels, and in particular to an automatic device for removing glass residues. Background Art

[0002] Existing technology manufactures liquid crystal panels for liquid crystal displays (LCDs) by cutting large glass substrates into the desired size and shape. The display panel in an LCD is composed of two glass substrates (a color filter substrate and an array substrate) with thin film layers formed on their upper and lower surfaces, and liquid crystal encapsulated between the substrates. During the manufacturing process, one surface of the glass substrate is first cut longitudinally and transversely, and then the other surface is cut longitudinally and transversely. During the cutting process, residual material is left at the edge of the glass substrate, which can cause damage to the subsequent processing steps of the glass substrate. Therefore, it is necessary to detect and precisely remove the residual material.

[0003] After glass cutting in the LCD and OLED panel industries, residual material wider than 1.5mm can be automatically removed by the equipment using methods such as ejector pin clamping, pressure rod pressing, and ejector pin pressing. However, residual material less than 1.5mm cannot be removed, and the removal process is prone to fragmentation and terminal scratches. Utility Model Content

After moving to the corresponding position, the cylinder is started to drive the pressure block at its output end to remove the glass residue. The surface of the pressure rod and the glass residue adopts a writing surface design.

[0016] By adopting the above technical solution, the first servo motor on the top of the residual material removal mechanism is installed on the mounting plate, and the screw rod at the output end of the first servo motor cooperates with the first thread sleeve on the back of the bracket to drive the main body in the bracket to move on the longitudinal slide rail through the longitudinal slider on the back, thereby realizing the lifting and lowering of the pressure rod; the screw rod at the output end of the second servo motor cooperates with the second thread sleeve on the back of the pressure rod to drive the transverse slider on the back of the pressure rod to move on the transverse slide rail on the surface of the bracket, realizing the forward and backward movement of the pressure rod, thereby adjusting according to glass of different sizes and glass of different stresses.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The pressure rod in this application adopts a sloped design, which allows the contact point of the glass residue to be subjected to forces in two directions, avoiding the traditional design of downward pressure in one direction. This can decompose the downward pressure into two directions, effectively reducing the fragmentation rate and terminal scratches.

[0021] 2. The position of the pressure rod and the angle of the pressure rod slope in this application are adjustable to meet the needs of glass of different sizes and to change the magnitude of the force in the two directions of decomposition of the downward pressure, corresponding to glass residues with different stresses.

The glass placement platform 3 on the device base 1 can load glass and move on the device base 1. The loaded glass moves to the bottom of the residual material removal mechanism 2 through the channel under the glass placement platform 3. The residual material removal mechanism 2 drives the bracket 22 equipped with the pressure rod 23 downward through the drive of the first servo motor 21. After moving to the corresponding position, the cylinder 231 is started to drive the pressure block 232 at its output end to remove the glass residue. The surface of the pressure rod 23 that acts on the glass residue adopts a writing surface design. The contact point of the glass residue is subjected to forces in two directions, avoiding the traditional one-direction downward pressure design. The downward pressure can be decomposed into forces in two directions, effectively reducing the fragmentation rate and terminal scratches.

[0029] Reference Figure 1 、 Figure 2 and Figure 3There are at least two glass placement platforms 3, one on each side of the waste material removal mechanism 2. The design of at least two glass placement platforms 3 can take into account both the placement and waste material removal functions, and more glass placement platforms 3 moving on the device base 1 can achieve continuous and automated waste material removal.

[0030] Reference Figure 1 、 Figure 2 and Figure 3 The glass placement platform 3 has a number of vacuum adsorption holes 32 evenly distributed on its surface. These holes are connected to a negative pressure pump 33 inside the platform 3. The glass mounted on the platform 3 is stably adsorbed on the platform 3 through the vacuum adsorption holes 32 under the action of the negative pressure pump 33, ensuring stability during glass scrap removal.

[0031] Reference Figure 1 、 Figure 2 and Figure 3 The top of the scrap material removal mechanism 2 is fixed with a fixed plate 24 for installing a first servo motor 21, wherein the output end of the first servo motor 21 drives a bracket 22 to control the lifting of the pressure rod 23. The bracket 22 includes a main body 221 and a transverse slide 2211 installed on the surface of the main body 221 and a longitudinal slider 2212 installed on the back of the main body 221, wherein the longitudinal slider 2212 is adapted to the longitudinal slide 25 on the scrap material removal device, and the back of the pressure rod 23 moves on the transverse slide 2211 through a transverse slider 233. The back of the bracket 22 is fixedly installed with a first threaded sleeve, wherein the first threaded sleeve cooperates with the screw rod at the output end of the first servo motor 21 for transmission.

The first servo motor 21 at the top of the residual material removal mechanism 2 is installed on the mounting plate 2321. The screw rod at the output end of the first servo motor 21 cooperates with the first thread sleeve on the back of the bracket 22 for transmission, driving the main body 221 in the bracket 22 to move on the longitudinal slide rail 25 through the longitudinal slider 2212 on the back, thereby realizing the lifting and lowering of the pressure rod 23; the screw rod at the output end of the second servo motor 222 cooperates with the second thread sleeve on the back of the pressure rod 23 for transmission, driving the transverse slider 233 on the back of the pressure rod 23 to move on the transverse slide rail 2211 on the surface of the bracket 22, realizing the forward and backward movement of the pressure rod 23, thereby adjusting according to glass of different sizes and glass of different stresses.

The actuating block 2322 is pivotally connected to the mounting plates 2321. A locking nut 2323 is mounted on the outer side of the mounting plates 2321 to lock the actuating block 2322 in place. The actuating block 2322 of the pressure block 232 at the output end of the cylinder 231 can rotate on the mounting plates 2321, thereby adjusting the angle of contact between the pressure block 232 and the glass remnant. This allows the magnitude of the downward force decomposition in both directions to vary, corresponding to glass remnants with varying stresses.

[0033] Working principle: When the glass residue removal device is working, the glass to be processed is placed on the glass placement platform 3. Under the action of the negative pressure pump 33, the glass is fixed on the glass placement platform 3 through the vacuum adsorption hole 32. The glass placement platform 3 is moved to the bottom of the pressure rod 23 of the residue removal mechanism 2, and the first servo motor 21 and the second servo motor 222 are driven to adjust the pressure rod 23 to the position corresponding to the glass residue. Then, the angle between the pressure block 232 on the pressure rod 23 and the contact surface of the glass is adjusted and locked. The cylinder 231 is started and the pressure is controlled by the electrical proportional valve. The pressure block 232 at the output end of the cylinder 231 is driven to remove the glass residue. After the removal of the glass residue is completed, the glass is transported away, and the glass placed on another glass placement platform 3 is transported to this platform to continue removing the glass residue.
