Description

Technical Field

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

[0002] In the automated manufacturing process of LCD panels, semi-finished LCD panels need to be transferred between different production stages. During the connection between upstream and downstream processes, due to differences in start-up times or the need for temporary shutdowns in downstream processes for various reasons, it is necessary to temporarily store the semi-finished LCD panels to ensure the continuity of automated production. Existing transfer mechanisms only serve a transfer function, moving LCD panels from upstream to downstream processes. In such cases, the upstream process also needs to stop and wait, or temporarily store the LCD panels on trays until the process resumes. Stopping and waiting reduces production efficiency, while directly stacking LCD panels on trays requires manual loading upon restarting production. Furthermore, in some processes, stacking semi-finished LCD panels may affect subsequent assembly and processing. Therefore, how to temporarily store LCD panels at transfer stations is a problem that those skilled in the art need to consider. Utility Model Content

[0003] The purpose of this invention is to provide a liquid crystal panel transfer compartment to solve the problem that liquid crystal panels are not easy to temporarily store at the connection between upstream and downstream processes in the prior art.

[0004] The technical solution of this utility model is: a liquid crystal panel transfer chamber, including a frame, two hopper assemblies disposed within the frame, and a transfer assembly disposed between the two hopper assemblies, wherein the transfer assembly moves between the two hopper assemblies.

The rack assembly includes a first support and multiple carrier plates disposed on the first support. The multiple carrier plates are arranged in multiple layers, with two carrier plates per layer, and are symmetrically arranged. The two carrier plates in each layer are connected to the first support on opposite sides. The transfer assembly moves between the carrier plates on both symmetrical sides and transfers the LCD panel onto the carrier plates, so that the two sides of the LCD panel respectively overlap the two carrier plates on the same layer.

[0006] Preferably, the lifting device includes a top plate mounted on the frame, a lifter connected to the top plate, and the lifter being connected to the first support.

[0007] Preferably, the projection of the first support in the vertical direction is U-shaped, and the transfer component can drive the liquid crystal panel to move into the opening of the U-shape.

[0008] Preferably, the lower end of the top plate is provided with a plurality of vertical guide rods, the guide rods are connected to guide sleeves provided on the first bracket, and the lifter drives the first bracket to move on the guide rods.

[0009] Preferably, the transfer assembly includes a first linear module with a horizontal driving direction and a second bracket connected to the first linear module; the first linear module drives the first bracket to move between the hopper assemblies to pick up and place the liquid crystal panel.

[0010] Preferably, the second bracket includes a base plate connected to the first linear module and a plurality of support blocks disposed on the base plate; the plurality of support blocks are detachably connected to the base plate and can be positioned on the base plate to accommodate LCD panels of different sizes and specifications.

[0015] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1-3 As shown, this utility model is applied in an automated LCD panel production line, connecting two processes and providing intermediate and temporary storage for LCD panels. LCD panels produced by upstream components are transferred to a transfer assembly. At this time, the second support of the transfer assembly is located between two hopper assemblies, receiving the LCD panel. Then, the transfer assembly drives the LCD panel to the hopper assembly, directly above the carrier plate. A lifting device drives the carrier plate upwards, with the carrier plate supporting the LCD panel on both lower sides, detaching it from the second support and completing the storage. Specifically: A liquid crystal panel transfer chamber includes a frame 1, two hopper assemblies 2 disposed within the frame 1, and a transfer assembly 3 disposed between the two hopper assemblies 2, the transfer assembly 3 moving between the two hopper assemblies 2.

[0016] The hopper assembly 2 includes a lifting device 21 and a rack assembly 22 connected to the lifting device 21. The lifting device 21 can drive the rack assembly 22 to move in the vertical direction. The rack assembly 22 includes a first support 221 and multiple carrier plates 222 disposed on the first support 221. The multiple carrier plates 222 are arranged in multiple layers, with two plates in each layer and symmetrically arranged. The two carrier plates 222 in each layer are connected to the first support 221 on the side that is far away from each other. The projection of the first support 221 in the vertical direction is U-shaped.

[0017] The lifting device 21 includes a top plate 211 mounted on the frame 1, a lifter 212 connected to the top plate 211, and the lifter 212 connected to the first support 221. Multiple vertical guide rods are provided at the lower end of the top plate 211, and the guide rods 213 are connected to guide sleeves provided on the first support 221. The lifter 212 drives the first support 221 to move on the guide rods 213.

[0018] In this embodiment, the two hopper components 2 are independently configured but share the transfer component 3. When storing the LCD panel, one hopper component 2 can be used first, and the other hopper component 2 can be placed after it is full; alternatively, the two hopper components 2 can be placed alternately. When storing the LCD panel, the carrier plate 222 of the hopper component 2 moves upward gradually; when removing the LCD panel, the hopper component 2 moves downward gradually.

[0019] The transfer assembly 3 moves between two symmetrical carrier plates 222 and transfers the liquid crystal panel onto the carrier plates 222, so that the two sides of the liquid crystal panel overlap the two carrier plates 222 on the same layer. The transfer assembly 3 includes a first linear module 31 with a horizontal driving direction and a second support 32 connected to the first linear module 31; the first linear module 31 drives the first support 221 to move between the hopper assemblies 2 to pick up and place the liquid crystal panel. The second support 32 includes a base plate 321 connected to the first linear module 31 and a plurality of support blocks 322 disposed on the base plate 321.

[0020] In this embodiment, the first linear module 31 is horizontally positioned, and its maximum stroke at both ends of the second support 32 lies between the two carrier plates 222 on the same layer of the two hopper assemblies 2. The support block 322 is detachably connected to the base plate 321, allowing its position on the base plate 321 to accommodate LCD panels of different sizes. The width of the second support 32 should be less than the distance between the two carrier plates 222 on the same layer to avoid interference between the second support 32 and the carrier plates 222.

[0021] In this embodiment, the process of taking the liquid crystal panel out of the hopper assembly 2 is as follows: When placing the LCD panel, firstly, the material rack assembly 22 is at the maximum downward stroke of the lifting device 21, and the second support 32 is positioned between the two material hopper assemblies 2. The upstream transfer device places the LCD panel onto the second support 32. The first linear module 31 drives the second support 32 to one of the material hopper assemblies 2, at which point both ends of the LCD panel are directly above the two carrier plates 222 on the same layer. The lifting device 21 drives the carrier plates 222 to move upward along the guide rod via the first support 221, causing the two carrier plates 222 to lift the LCD panel upward from both sides, thus detaching the LCD panel from the second support 32 and completing the temporary storage of the LCD panel. Afterward, the second support 32, driven by the first linear module 31, returns to the center position between the two material hopper assemblies 2.

[0022] When the LCD panel of the hopper assembly 2 is removed, the second support 32 moves to the hopper assembly 2 and is directly below the bottom LCD panel; the lifting device 21 drives the LCD panel to move downward through the first support 221, so that the lower end of the LCD panel contacts the second support 32 and the sides are separated from the carrier plate 222; the second support 32 moves to the center between the two hopper assemblies 2 under the drive of the first linear module 31, and the LCD panel is removed by the downstream process or the robotic arm.

[0023] It should be noted that when the lifting device 21 drives the material rack assembly 22 to its maximum vertical stroke, the uppermost carrier plate 222 should be slightly lower than the upper surface of the second support 32, preferably by half the distance between two adjacent carrier plates 222. When the lifting device 21 drives the material rack assembly 22 to its maximum vertical stroke, the lowermost carrier plate 222 should be higher than the upper surface of the second support 32, preferably by half the distance between two adjacent carrier plates 222. When placing or removing the LCD panel, the lifting device 21 drives the carrier plate 222 up or down by a distance equal to the distance between two adjacent carrier plates 222 each time. Furthermore, the distance between two adjacent carrier plates 222 should be greater than or significantly greater than the thickness of the LCD panel to avoid interference between the LCD panel and the carrier plate 222 when the LCD panel bends due to strength limitations.

[0024] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
