Description

Technical Field

[0001] This utility model relates to the field of panel transfer technology, and in particular to a panel conveying mechanism. Background Technology

[0002] In the manufacturing process of products such as LCD panels and glass panels, the panels need to be cleaned and optically inspected. Generally, the LCD panels need to be transferred from the previous station to the cleaning or inspection equipment and placed horizontally on the inspection platform to facilitate optical inspection.

[0003] In existing technologies, robotic arms are typically used to grip and transfer panels. However, different gripping devices are required for panels of different sizes, making the operation complex. Furthermore, panels are generally thin but large, making them prone to bending and deformation during handling and transfer. Panels are usually transported to the conveyor mechanism by forklifts or other transfer equipment. During placement, friction between the forklift forks and the panel can cause damage. Therefore, how to stably transfer panels of various sizes is a problem that those skilled in the art need to consider. Utility Model Content

[0030] The present invention will be further described in detail below with reference to specific embodiments:

[0031] like Figures 1-5 As shown, this utility model is applied to the transport of LCD panel-shaped items. After the LCD panels are formed or before assembly, they need to be cleaned and inspected. The LCD panels are transported piece by piece to the cleaning and inspection equipment using forklifts or other transfer equipment. Although forklifts or pallet trucks can complete the basic transport of the panels, their associated hydraulic lifting systems and guiding devices often have significant positional deviations. Operators find it difficult to make fine adjustments and accurately place the panels when visually positioning them. Therefore, a conveying mechanism is set up to position and transport the panels. The panel is placed on the top of a push rod, and the forklift or other transport equipment is removed; the push rod descends, causing the panel to fall to the conveying mechanism; simultaneously, a second positioning component pushes the panel against the first positioning component, completing the positioning. Specifically:

[0032] A panel conveying mechanism includes a frame 1, a conveying mechanism 2, a positioning mechanism 3 and a lifting mechanism 4 disposed on the frame 1.

[0033] The conveying mechanism 2 includes multiple conveying rods 21 arranged in parallel, and each conveying rod 21 is equipped with multiple rollers 22. A motor 23 is connected to the conveying rod 21, and the motor 23 can drive multiple conveying rods 21 to rotate simultaneously, thereby driving the rollers 22 to rotate to convey the panel.

[0034] The positioning mechanism 3 includes a first positioning component 31 and multiple sets of second positioning components 32. The first positioning component 31 includes multiple first positioning rods 311 arranged in parallel. The first positioning rods 311 are vertically arranged, with their lower ends connected to a first bracket 312. The first bracket 312 is connected to the frame 1 via a first slide rail 313. The first positioning rods 311 are located on one side of the conveying mechanism 2. In this embodiment, the distance between the first positioning rods 311 and the conveying mechanism 2 is adjusted by sliding the first slide rail 313 according to the different specifications of the panels being conveyed, and then locked after adjustment.

[0035] Each set of second positioning components 32 is connected to multiple parallel second positioning rods 321. The second positioning rods 321 pass upward through the conveying mechanism 2 and move towards the first positioning rod 311. The second positioning rods 321 are vertically positioned and located on the side of the conveying mechanism 2 away from the first positioning rod 311. The lower end of the second positioning rod 321 is connected to a first driving device 322 with a vertical driving direction. Multiple first driving devices 322 are simultaneously connected to a second bracket 323. The second bracket 323 is connected to the frame 1 through a second driving device 324 with a horizontal driving direction. The second driving device 324 can drive the second positioning rods 321 to move closer to or away from the first positioning rod 311. In this embodiment, two sets of second positioning components 32 are provided, and the distance between the two sets of second positioning components 32 and the first positioning components 31 is different to accommodate the positioning of panels of different specifications. During panel transfer, the first driving device 322 drives the second positioning rod 321 to move upward until it passes through the conveying mechanism 2, and the second driving device 324 drives the second positioning rod 321 to move towards the first positioning rod 311 and abut against the panel until it abuts against the first positioning rod 311.

[0036] It should be noted that the above positioning process can be performed simultaneously during panel transfer. Therefore, a first bearing 3111 is provided at the top of the first positioning rod 311, and a second bearing 3211 is provided at the top of the second positioning rod 321. When pushing against the panel, the first bearing 3111 and the second bearing 3211 contact the edge of the panel. Through the rotation of the bearings, friction between the panel and the first positioning rod 311 or the second positioning rod 321 is avoided, thereby preventing damage to the panel.

[0037] The positioning mechanism 3 also includes a third positioning component 33, which is disposed at the downward end of the conveying mechanism 2 in the conveying direction. The third positioning component 33 includes a third positioning rod 331 and a first rotating device 332 that drives the third positioning rod 331 to rotate. The first rotating device 332 can rotate the third positioning rod 331 to a vertical position, making its upper end higher than the conveying mechanism 2. In this embodiment, the third positioning component 33 ensures that only one panel is conveyed at a time. When panels are continuously conveyed, the first rotating device 332 drives the third positioning rod 331 to rotate to a vertical position, temporarily blocking the panels.

[0038] The lifting mechanism 4 includes a lifting drive device 41 and a plurality of lifting rods 42 connected to the lifting drive device 41. The lifting drive device 41 can drive the lifting rods 42 to move vertically above or below the roller 22. The top end of the lifting rod 42 is spherical. The plurality of lifting rods 42 are connected to the lifting drive device 41 through a third bracket 43.

[0039] In this embodiment, when a forklift or other handling equipment transfers the panel to the top of the conveying mechanism 2, the lifting drive device 41 drives the push rod 42 to move upward through the conveying mechanism 2 to lift the panel on the handling equipment. After that, the handling equipment exits. The lifting drive device 41 drives the push rod 42 to move downward, so that the panel moves downward to the roller 22 of the conveying mechanism 2 and is transferred through the roller 22. During the transfer, the first drive device 322 drives the second positioning rod 321 to move upward, and the first drive device 322 drives the second positioning rod 321 to move in the direction of the first positioning rod 311, so that the edge of the second bearing 3211 abuts against the edge of the panel, so that the panel slides on the roller 22 in a direction perpendicular to the conveying direction until the other side of the panel abuts against the first bearing 3111 to complete the positioning.

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