Description

Technical Field

[0001] This utility model belongs to the field of liquid crystal display processing technology, and in particular relates to a feeding device for cutting liquid crystal display substrates with full viewing angle. Background Technology

[0002] Before processing LCD displays, the substrate needs to be cut to obtain the required substrate size. Full-view cutting devices are often used, which combine visual positioning with laser non-contact cutting through camera modules to reduce substrate damage rate. This can meet the processing needs of high-end products such as automotive displays. With high-precision control (such as laser positioning and CNC systems), multi-angle adaptability (such as tapered cutting and personalized parameter adjustment) and risk pre-control (such as homogenization and minimally invasive design) as the core, it is relatively advanced in display substrate cutting applications.

[0003] Since LCD substrate cutting is a batch operation and the substrates are standard parts, it is difficult to meet the needs of mass production of substrates by feeding the substrates one by one in the LCD substrate cutting process. Therefore, a feeding device for LCD substrate full-view cutting is needed. This device can place multiple substrates in a material tank, and then the bottom substrate is moved and fed by the friction of the conveyor belt, which meets the feeding requirements of substrates during substrate cutting production and thus ensures the processing speed. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for full-view cutting of liquid crystal display substrates. Multiple substrates are placed in a material trough, and then the bottom substrate is moved and fed by the friction of the transmission belt, which meets the feeding requirements of substrates during substrate cutting production, thereby ensuring processing speed and solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A feeding device for cutting a liquid crystal display substrate with a full viewing angle includes a frame: a material trough is fixedly connected to the surface of the frame, two symmetrically arranged drive rollers are rotatably connected to the inner wall of the frame, a driven roller is rotatably connected to the inner wall of the frame, a rectangular opening is provided on the right side of the material trough, a transmission belt is drivenly connected to the surface of the drive rollers, a motor is fixedly connected to the surface of the frame by bolts, a controller is fixedly connected to the surface of the frame by bolts, a cutting table is fixedly connected to the right side of the frame, a camera cutting assembly is installed on the surface of the cutting table, a second drive roller and a second driven roller are rotatably connected to the inner wall of the cutting table, a second motor is fixedly connected to the surface of the frame by bolts, and the output shaft of the second motor passes through the cutting table and is fixedly connected to the second drive roller.

[0006] Preferably, the output shaft of the first motor extends through the inner cavity of the frame and is fixedly connected to the first drive roller.

[0007] Preferably, the surface of the transmission belt is integrally formed with raised rubber blocks.

[0008] Preferably, an infrared sensor is fixedly connected to the surface of the frame by bolts, and the infrared sensor and the controller are electrically connected by wires.

[0009] Preferably, the inner wall of the frame is horizontally fixedly connected with a connecting rod.

[0010] The beneficial effects of this utility model are: 1. This utility model uses a motor to drive a driven roller to rotate, which in turn drives the bottom substrate in the material trough to move via a transmission belt. This allows the substrate to enter the drive roller and the driven roller through a rectangular opening. The substrate is then transported to the surface of the cutting table, thus allowing multiple substrates to be placed in the material trough. The friction of the transmission belt then drives the bottom substrate to move and feed, meeting the substrate feeding requirements during substrate cutting production and ensuring processing speed. 2. By setting the convex rubber blocks, this utility model increases the friction on the surface of the transmission belt, avoids relative sliding when the transmission belt directly contacts the substrate, and thus improves the accuracy of friction transmission. 3. This utility model monitors the material transfer in the drive roller 2 and the driven roller 2 by setting an infrared sensor. When the substrate stops, the infrared sensor transmits a signal to the controller to control the motor 1 and the camera cutting assembly to shut down, so as to avoid the components from continuing to operate when the material transfer fails, thereby reducing the impact of the failure. 4. By setting up connecting rods, this utility model strengthens the structure of the frame, preventing it from becoming loose and wobbly after long-term use, thereby improving the stability of the frame structure.

Example

[0015] Figure 1-4This invention illustrates a feeding device for full-view cutting of liquid crystal display substrates according to an embodiment of the present invention. It includes a frame 1; a material trough 2 is fixedly connected to the surface of the frame 1; two symmetrically arranged drive rollers 3 are rotatably connected to the inner wall of the frame 1; a driven roller 4 is rotatably connected to the inner wall of the frame 1; a rectangular opening 5 is provided on the right side of the material trough 2; a transmission belt 6 is drivenly connected to the surface of the drive rollers 3; a motor 7 is fixedly connected to the surface of the frame 1 by bolts; a controller 10 is fixedly connected to the surface of the frame 1 by bolts; and an infrared sensor 9 is fixedly connected to the surface of the frame 1 by bolts. The infrared sensor 9 and the controller 10 are electrically connected by wires. The infrared sensor 9 monitors the material transfer in the drive rollers 13 and driven rollers 14, and detects when the substrate stops moving. Infrared sensor 9 transmits a signal to controller 10 to shut down motor 7 and camera cutting assembly 12, preventing the components from continuing to operate during material transfer failures and thus reducing the impact of the failure. A cutting table 11 is fixedly connected to the right side of frame 1, and camera cutting assembly 12 is installed on the surface of cutting table 11. Drive roller 13 and driven roller 14 are rotatably connected to the inner wall of cutting table 11. Motor 15 is fixedly connected to the surface of frame 1 by bolts.

The connecting rod 16 reinforces the structure of frame 1, preventing the frame 1 from becoming loose and wobbly after long-term use, thereby improving the stability of the frame 1 structure.

[0016] Working principle: When using this utility model, the user places multiple substrates into the inner cavity of the material tank 2, and then the driven roller 4 is rotated by the motor 7. The driven roller 4 moves the bottom substrate in the material tank 2 through the transmission belt 6, so that the substrate enters the drive roller 13 and the driven roller 14 through the rectangular opening 5. At this time, the drive roller 13 is rotated by the motor 15, and the cooperation of the drive roller 13 and the driven roller 14 drives the substrate to the surface of the cutting table 11. Then, the camera module in the camera cutting assembly 12 combines visual positioning with laser non-contact cutting to cut the substrate from all angles. This realizes that multiple substrates are placed in the material tank, and then the friction of the transmission belt drives the bottom substrate to move and feed, which meets the feeding requirements of substrates during substrate cutting production, thereby improving the efficiency of substrate cutting processing.

[0017] In summary, this full-view cutting feeding device for LCD display substrates uses a motor 7 to drive a driven roller 4 to rotate. This driven roller 4 then moves the substrate at the bottom of the material trough 2 via a transmission belt 6. The substrate then enters the drive roller 13 and driven roller 14 through the rectangular opening 5. Subsequently, the substrate is transported to the surface of the cutting table 11, thus placing multiple substrates in the material trough. The friction of the transmission belt then moves the bottom substrate for feeding, meeting the feeding requirements of substrates during substrate cutting production and ensuring processing speed.
