Description

Technical Field

[0002] At present, in the production process of liquid crystal display devices (LCD), the technical bottleneck of the material collection link has become a key factor restricting the upgrading of the industry. The current industry generally adopts the manual material collection method, and the operators need to directly contact the precision components to complete the material sorting and stacking. This mode is prone to fluctuations in the intensity of the operation, which leads to a decrease in the stability of the production cycle. At the same time, it is difficult to avoid micro-surface damage caused by physical contact during repeated handling, resulting in a loss of product yield.

[0003] The traditional manual material collection system has multi-dimensional technical defects. First, the operating efficiency of personnel is limited by physiological functions and experience levels, and cannot adapt to the needs of high-speed continuous production. Especially when dealing with high-value-added products such as large-size panels, the contradiction between operating accuracy and speed is further aggravated. In addition, the quality risks caused by manual intervention run through the entire process, from static electricity accumulation during component grabbing to judgment errors in visual inspection, which may cause hidden defects to be transmitted to downstream processes; in addition, if the racks used to place LCD components have defects, they will collide with LCD components during the material collection process, causing damage to the LCD components, affecting product quality and production efficiency.

[0032] like Figure 1 and Figure 2 As shown, an automatic material receiving device for LCD strip racks according to a preferred embodiment of the present invention comprises a base 1, and the base 1 is used to support various mechanisms of the automatic material receiving device for LCD strip racks.

The feeding mechanism extends from the outside of the base 1 to the base 1, and is used to transport LCD components into the base 1. Specifically, the feeding mechanism 2 includes a conveyor belt horizontally arranged thereon, and the produced LCD components are continuously transported to the receiving mechanism 5 through the conveyor belt; the flipping mechanism 3 is arranged on one side of the feeding mechanism 2, and the flipping mechanism 3 includes a first fixing device 31 for clamping the LCD component and a rotating device 32 connected to the first fixing device 31. Since the conveyor belt transports horizontally placed LCD components, the flipping mechanism 3 is required to flip the LCD component to a vertical state, so that the LCD component can be finally vertically inserted into the material tray; the first transfer mechanism 4 is arranged above the feeding mechanism 2 and the flipping mechanism 3, and the first transfer mechanism 4 includes a first slide rail 41 and a first suction device 42 slidably connected to the first slide rail 41. The first suction device 42 is used to transport the horizontally placed LCD component from the feeding mechanism 2 to the flipping mechanism 3, and then the LCD component is flipped by the flipping mechanism 3.

The material rack pre-storage mechanism 7 includes a material rack positioning device and a material rack detection device. Before the material rack is placed on the material receiving mechanism 5, it is detected at the material rack pre-storage mechanism 7.

The flipping mechanism 3 fixes the horizontal LCD components through the first fixing device 31, and then rotates the LCD components through the flipping device to make them vertical, so that the second transfer mechanism 6 can take out the LCD components from the flipping mechanism 3 and insert them into the material rack. The material rack is placed on the receiving device. After being detected by the material rack pre-storage mechanism 7, the material rack is placed on the material rack bearing platform.

[0037] In some embodiments of the present invention, a material rack pre-storage mechanism 7 is arranged on one side of a material receiving mechanism 5, and a third transfer mechanism 8 is arranged above the material receiving mechanism 5 and the material rack pre-storage mechanism 7, and the third transfer mechanism 8 is used to transfer the material rack from the material receiving mechanism 5 to the slider 52; the coordinated layout of the material rack pre-storage mechanism 7 and the material receiving mechanism 5 realizes the isolation of detection and material receiving through the third transfer mechanism 8. The present application arranges the material rack pre-storage mechanism 7 in the material receiving device, fully utilizes the space of the material receiving device, and improves the integration of the device; testing the material rack before receiving the material is also beneficial to ensure that the LCD components are safely and reliably fixed in the material rack rack, and prevents the interference between the material rack rack and the LCD components, which causes the LCD components to be scrapped.
