Description

LCD screen processing and transfer device Technical Field

[0001] This utility model relates to the field of processing and transfer, specifically to a liquid crystal display screen processing and transfer device. Background Technology

[0002] In the mass production of LCD panels, all screens need to be inspected. Typically, a vacuum suction cup is used to pick up the screens on the production line and transfer them to the inspection station.

[0003] Existing adsorption equipment, such as the liquid crystal display processing and transfer device disclosed in the Chinese Patent Database (application number: 202321901277.2), includes a vacuum pump, a long strip-shaped and horizontally arranged base, and a vacuum suction cup vertically arranged on one side of the base. The top and bottom surfaces of the base are both provided with grooves running through the length of the base. Two slides are symmetrically arranged vertically, and the openings of the grooves are constricted. Sliding blocks with shapes and sizes matching the grooves slide within the grooves. Positioning blocks and connecting pieces are horizontally pressed on the top and bottom surfaces of the base, respectively. One end of the connecting piece and the positioning block are fixed to the corresponding sliding blocks through vertically arranged rod-shaped connectors. The upper end of the vacuum suction cup is fixed to the other end of the connecting piece. The vacuum pump is horizontally fixed on the top wall of the positioning block, and the top wall of the positioning block can undergo elastic deformation.

[0004] The aforementioned gripping device lacks consideration of the impact of the reciprocating motion of the processing transfer device on operational stability. Furthermore, simply setting up two suction cups is not conducive to truly stable transfer, and the operation process of the vacuum pump in conjunction with the processing transfer device is also lacking design.

[0005] Therefore, those skilled in the art have provided a liquid crystal display processing and transfer apparatus to solve the above-mentioned problems. Summary of the Invention

[0006] To solve the above-mentioned technical problems, this utility model provides a liquid crystal display screen processing and transfer device, including a motion component, a power component, a suction component, and a controller;

[0007] Preferably: the eccentric disk of the motion component is connected to the gear set of the power component via a transmission shaft one; the motion component is connected to the hanging rod of the suction component via a hanging rod; the inner side of the eccentric disk is connected to the transmission shaft one; the outer ring of the eccentric disk is connected to one end of the irregular connecting rod one; the other end of the irregular connecting rod one is connected to one end of the connecting rod two via a shaft; the other end of the connecting rod two is connected to the frame two; the left side of the frame two is connected to the connecting rod four; the right side is connected to the connecting rod two and the connecting rod three; the left side of the hanging rod is connected to the connecting rod four; the right side of the hanging rod is connected to the connecting rod three; the connecting rod two and the connecting rod three are fixedly connected; the motion component operates by receiving power from the power component and drives the hanging rod in a specific reciprocating trajectory, thereby driving the suction component to pick up and place; the motion component moves synchronously with the symmetrical motion component.

[0008] Preferably: the power component is connected to the controller via wire one and to the eccentric disc via drive shaft one. The motor is mounted on the base with bolts. Wire one is connected to one side of the motor. Drive shaft two is provided at one end of the motor. Drive shaft two is mounted on frame three. Drive shaft two is connected to a gear set. The gear set is mounted on drive shaft two and drive shaft one. The gear set has symmetrical gear sets along the opposite side of the suction component. Drive shaft three is provided at the right end of drive shaft two. Symmetrical gear sets are provided on the right side of drive shaft three.

[0009] Preferably, the controller is connected to an external power source, and one side of the controller is connected to line two and wire one. The controller can time according to a set pattern and intermittently supply power to line two and wire one. The controller causes the motion component to pause briefly when it reaches the lowest point and the second lowest point. At this time, the suction component performs the operation. When the hanger moves to the lowest point on the left, that is, when the suction cup contacts the upper surface of the LCD screen workpiece, the controller simultaneously starts the vacuum generator to generate suction. When the hanger moves to the right platform, the controller cuts off the power to the vacuum generator, the suction cup releases the workpiece, and the processing and transfer process is completed. After that, the controller continues to intermittently supply power to wire one, so that the motion component, the power component and the suction component keep reciprocating in a cycle.

The vacuum generator is installed on the aluminum profile in the middle of the hanger and is connected to line two. Line two is installed in the wire clip. There are multiple wire clips, which are fixed to the hanger, the hanging rod, the connecting rod four, and the frame two, respectively. When the vacuum generator is powered on, it generates suction force to make the suction cup operate and lift the LCD screen to move with the mounting rod. The three-way pipe plays the role of connecting and transmitting suction force.

The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0022] Please refer to Figures 1 to 4. In this embodiment, a liquid crystal display screen processing and transfer device is provided, including a motion component 1, a power component 2, a suction component 3, and a controller 4. The eccentric disk 101 of the motion component 1 is connected to the gear set 202 of the power component 2 via a transmission shaft 205. The motion component 1 is connected to the lifting rod 301 of the suction component 3 via a hanging rod 106. The inner side of the eccentric disk 101 is connected to the transmission shaft 205, and the outer ring of the eccentric disk 101 is connected to one end of a shaped connecting rod 102. The other end of the shaped connecting rod 102 is connected to one end of a connecting rod 103 via a shaft. The other end of the second connecting rod 103 is connected to the second frame 502. The left side of the second frame 502 is connected to the fourth connecting rod 104, and the right side is connected to the second connecting rod 103 and the third connecting rod 105. The left side of the hanging rod 106 is connected to the fourth connecting rod 104, and the right side of the hanging rod 106 is connected to the third connecting rod 105. The second connecting rod 103 and the third connecting rod 105 are fixedly connected. The motion component 1 operates by receiving power from the power component 2 and drives the hanging rod 106 in a specific reciprocating trajectory, thereby driving the suction component 3 to pick up and place. The motion component 1 moves synchronously with the symmetrical motion component 11.

[0023] The power assembly 2 is connected to the controller 4 via wire 402 and to the eccentric disk 101 via drive shaft 205. The motor 201 is bolted to the base 206. One side of the motor 201 is connected to wire 402. One end of the motor 201 is provided with drive shaft 207, which is mounted on frame 503. Drive shaft 207 is connected to gear set 202, which is mounted on drive shaft 207 and drive shaft 205. The gear set 202 has a symmetrical gear set 204 along the opposite side of the suction assembly 3. The right end of drive shaft 207 is provided with drive shaft 208, and the right side of drive shaft 208 is provided with symmetrical gear set 204. Drive shaft 208 ensures that the motion assembly 1 and the symmetrical motion assembly 11 operate synchronously.

[0024] The lifting rod 301 is mounted on the hanging rod 106 and is fixedly connected to the hanger 302. The suction cup 303 is mounted on the hanger 302, and its upper end is connected to the vacuum hose 308. A three-way pipe 306 is installed on each of the left and right sides of the hanger 302. The three-way pipe 306 is connected to three vacuum hoses 308. The vacuum hoses 308 on both sides of the three-way pipe 306 are connected to the suction cup 303, while the middle vacuum hose 308 is connected to the vacuum generator 305. Vacuum generator 305 is installed on the aluminum profile in the center of hanger 302. Vacuum generator 305 is connected to line 2 304. Line 2 304 is installed in wire clip 307. There are multiple wire clips 307, which are respectively fixed on hanger 302, hanger rod 301, connecting rod 4 104 and frame 2 502. After vacuum generator 305 is powered on, it generates suction force to make suction cup 303 operate and lift up the LCD screen to move with the mounting rod 106. The three-way pipe 306 plays the role of connecting and transmitting suction force.

[0025] The controller 4 is connected to an external power source. One side of the controller 4 is connected to line 2 304 and wire 1 402. The controller 4 can time according to a set pattern and intermittently supply power to line 2 304 and wire 1 402. The controller 4 causes the motion component 1 to pause briefly when it reaches the lowest point and the second lowest point. At this time, the suction component 3 performs the operation. When the hanger 302 moves to the lowest point on the left, that is, when the suction cup 303 contacts the upper surface of the LCD screen workpiece, the controller 4 simultaneously starts the vacuum generator 305 to generate suction. When the hanger 302 moves to the right platform, the controller 4 cuts off the power to the vacuum generator 305, and the suction cup 303 releases the workpiece, completing the processing and transfer process. After that, the controller 4 continues to intermittently supply power to wire 1 402, so that the motion component 1, the power component 2 and the suction component 3 keep reciprocating in a cycle.

[0026] The motion component 1 operates as follows: The direction of link 2 103 relative to the direction of eccentric disk 101 is referred to as the left end of eccentric disk 101. Eccentric disk 101, powered by drive shaft 1 205, begins to rotate counterclockwise. When eccentric disk 101 moves to its leftmost end around drive shaft 1 205, link 2 103 also moves to its leftmost end. At this time, the mounting rod 106 moves to its rightmost end, reaching its lowest point in height. Afterward, eccentric disk 101 falls back to the right. Link 2 103 is driven to fall back to the right by eccentric link 1 102. The connection between link 4 105 and link 2 103 prevents relative rotation. The rotation of link 4 105 causes the mounting rod... 106 is raised, with connecting rod 3 104 and connecting rod 4 105 always parallel. The eccentric disk 101 continues to rotate and reaches the rightmost end. During this process, the mounting rod 106 rotates to the left. After the mounting rod 106 rises to its highest point, it descends to its leftmost end, which is also the second lowest point it can reach. After that, the eccentric disk 101 rotates upward, and the mounting rod 106 rises and returns to the highest point it just moved. Finally, with the rotation of the eccentric disk 101, the mounting rod 106 descends to the lowest point, achieving a cyclical motion. Throughout the entire process, the eccentric disk 101 always makes a complete counterclockwise circular motion around the transmission shaft 1 205, while connecting rod 2 103, connecting rod 4 105, and connecting rod 3 104 rotate back and forth in the fan-shaped area.
