Description

Technical Field

[0001] This utility model relates to the field of liquid crystal panel assembly technology, and in particular to a panel assembly transfer device. Background Technology

[0002] In the manufacturing process of LCD panels, the panel and back panel need to be assembled. Currently, this assembly is typically done manually. During manual operation, the protective film on the adhesive strip of the panel must first be removed before transferring it to the back panel for assembly. This process is prone to accidental contact with the adhesive strip, causing contamination and affecting adhesion. Furthermore, pressure is required after assembly to ensure stable assembly. Therefore, the back panel is usually placed face up on the worktable, with the panel's protective film side facing up. After removing the protective film, the panel is flipped 180 degrees and assembled with the back panel. During this flipping process, the operator's handling of the panel can affect the cleanliness of the panel surface. Additionally, smaller panels are easier to flip by hand, while larger panels, when flipped, can bend due to the operator holding them by the sides, potentially causing damage.

[0003] Furthermore, manual assembly relies on the experience and patience of operators, and prolonged operation can easily lead to operator fatigue, causing misalignment during bonding and resulting in product quality issues. Moreover, manual labor is labor-intensive and inefficient. Therefore, how to avoid panel contamination when removing the protective film and how to increase the stability of panel and back panel assembly are issues that those skilled in the art need to consider. Utility Model Content

[0004] The purpose of this invention is to provide a panel assembly and transfer device to solve the problems in the prior art, such as easy contamination after the protective film of the panel is removed, and low accuracy and efficiency in assembling with the back panel.

[0005] The technical solution of this utility model is: a panel assembly and transfer device, including an X-axis drive assembly, a Y-axis drive assembly and a Z-axis drive assembly connected in sequence. The Z-axis drive assembly is connected to a first rotating device with a vertical rotation axis through a first bracket. The first rotating device is connected to a second rotating device with a horizontal rotation axis through a second bracket. The second rotating device is connected to a pickup assembly through a third bracket. The second bracket is provided with at least two first sensors, and the third bracket is connected to a shaft. The axis of the shaft coincides with the axis of rotation of the second rotating device. The end of the shaft is connected to a first sensing plate. When the shaft rotates with the third bracket, the first sensing plate can sequentially sense the two first sensors.

[0006] Preferably, the second support includes a first base plate connected to the first rotating device and two first upright plates connected to the first base plate; The third support includes two second upright plates, which are disposed on both sides of the two first upright plates and rotatably connected; the second rotating device is fixedly connected between the two first upright plates, and its driving end extends out of the first upright plate and connects with the second upright plate to drive the second upright plate to rotate relative to the first upright plate.

[0007] Preferably, a third upright plate is also connected to the second bracket, and the first sensor is disposed on the third upright plate.

[0008] Preferably, the pickup assembly includes a plurality of suction nozzles connected to the two second upright plates, and two clamping devices connected to the third bracket and symmetrically arranged on both sides of the plurality of suction nozzles.

[0009] Preferably, the clamping device includes a clamping drive device and two grippers connected to the clamping drive device; The gripper includes a connecting part connected to the gripping drive device, a gripping part connected to the connecting part, and a support part connected to the gripping part. The connecting part, gripping part, and support part are U-shaped as a whole. During gripping, the support parts of the two grippers abut against each other.

[0010] Preferably, when the gripper clamps, the upper surfaces of the two support portions form a support surface.

[0011] Preferably, the clamping device is connected to the third bracket via a fourth bracket, and the connection position of the fourth bracket on the third bracket can be adjusted so that the clamping device is closer to or further away from the suction nozzle.

[0012] Compared with the prior art, the advantages of this utility model are: (1) This utility model avoids manual contact with the panel adhesive strip area through automatic transfer and flipping operations, eliminating the problem of adhesive strip contamination caused by accidental contact; it also reduces direct contact between human hands and the panel surface, ensuring the cleanliness of the panel surface; (2) Through the precise coordination of multiple drive shafts, the accurate positioning of the front panel and back panel is ensured, thus guaranteeing their assembly accuracy; The suction nozzle assembly picks up the center of the panel, and after the clamping assembly clamps it, the support surface supports both sides of the panel to prevent deformation of large-sized panels, thereby ensuring panel quality and assembly stability. (3) Picking up the panel: After picking up the panel, the panel can be flipped less than 180 degrees so that the side of the panel with the protective film faces the operator, which makes it easier for the operator to peel off the film and reduces the labor intensity of the operator; and the flipping range is smaller, which reduces the process time.

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1-5 As shown, this utility model is applied in the assembly of liquid crystal panels, specifically for the picking, transferring, and assembling of the panels. The picking device picks up the panel and rotates it to approximately 145° so that the side with the protective film faces the operator. After the operator removes the protective film, the transfer device drives the panel to rotate in the opposite direction so that the adhesive strip side faces down. The position and angle of the panel are adjusted by the X-axis drive assembly 1, the Y-axis drive assembly 2, and the first rotation device, positioning it directly above the back panel. Then, the Z-axis drive assembly drives the panel downwards to complete the assembly with the back panel. Specifically: A panel assembly and transfer device includes an X-axis drive assembly 1, a Y-axis drive assembly 2, and a Z-axis drive assembly 3 connected in sequence. The Z-axis drive assembly 3 is connected to a first rotating device 4 with a vertical rotation axis via a first bracket 41.

The clamping devices 7 are connected to the third bracket 61 via a fourth bracket 71, and the position of the fourth bracket 71 on the third bracket 61 can be adjusted so that the clamping devices 7 are closer to or further away from the suction nozzles 62.

[0018] The clamping device 7 includes a clamping drive device 72 and two grippers 73 connected to the clamping drive device 72. Each gripper 73 includes a connecting portion 731 connected to the clamping drive device 72, a clamping portion 732 connected to the connecting portion 731, and a supporting portion 733 connected to the clamping portion 732. The connecting portion 731, clamping portion 732, and supporting portion 733 are generally U-shaped. During clamping, the supporting portions 733 of the two grippers 73 abut against each other. When the grippers 73 are clamping, the upper surfaces of the two supporting portions 733 form supporting surfaces 7331.

[0019] A third upright plate 513 is also connected to the second support 51, and a first sensor 52 is mounted on the third upright plate 513. At least two first sensors 52 are provided.
