Description

Technical Field

[0001] This utility model relates to the field of panel flipping and stacking technology, and in particular to a panel flipping and stacking device. Background Technology

[0002] Products with panel-like structures, such as LCD panels and trays, require stacking for storage or transport when manufactured as semi-finished or finished products. Some panels have specific top-to-bottom stacking requirements, necessitating a 180° flip before stacking. Existing technologies use robotic arms to grip the edges of the panels for flipping. However, when flipping larger panels, the panel's insufficient rigidity can easily cause bending and deformation when the sides are gripped and the panel is suspended in the air, leading to damage or detachment and potentially accidents. Therefore, designing a dedicated panel flipping device suitable for flipping and stacking panels of different sizes 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 panel flipping and stacking device to solve the problems of poor versatility of existing panel flipping equipment.

[0004] The technical solution of this utility model is: a panel flipping and stacking device, comprising: A flipping mechanism includes a first conveying device, a second conveying device, and a flipping device, wherein the flipping device is disposed between the first conveying device and the second conveying device; the flipping device includes a flipping rod and a flipping drive device for driving the flipping rod to rotate. The positioning mechanism includes a third conveying device and a first positioning plate and a second positioning plate disposed on both sides of the third conveying device. When the panel is conveyed to the third conveying device, the first positioning plate moves toward the side closer to the second positioning plate and pushes the panel against the first positioning plate. The stacking mechanism includes a fourth conveying device, a suction cup assembly, and a transfer device connected to the suction cup assembly. The suction cup assembly picks up the panels on the third conveying device and moves them to the fourth conveying device for stacking under the drive of the transfer device. The flipping rod includes a loading end and a unloading end. When the flipping rod rotates, the loading end is supported by the first conveying device, and the unloading end places the panel at the second conveying device.

[0005] Preferably, both the first and second conveying devices are roller conveyors, and the flipping rod passes sequentially between two adjacent rollers of the first and second conveying devices when it rotates.

[0006] Preferably, the flipping device includes a rotating shaft, on which a flange is fixedly connected, and the flipping rod is connected to the flange; The flange is provided in multiple ways, and each flange is connected to multiple flipping rods.

[0007] Preferably, the positioning mechanism further includes a first bracket, and the first positioning plate and the second positioning plate are respectively connected to the first bracket via a first slide rail and a second slide rail; the first slide rail and the second slide rail are parallel to each other; The first bracket is connected to a first direct drive device, which is connected to a first positioning plate and can drive the first positioning plate to reciprocate on the first slide rail.

[0008] Preferably, the positioning mechanism includes two pulleys disposed on the first bracket and an annular belt connected by the two pulleys. The two pulleys divide the annular belt into two symmetrical parts, which are respectively connected to the first positioning plate and the second positioning plate. When the first direct drive device drives the first positioning plate to move, it drives the second positioning plate to move synchronously on the second slide rail via a ring belt, so that the first positioning plate and the second positioning plate move closer or further away from each other synchronously.

[0009] Preferably, the positioning mechanism further includes a baffle, which is disposed at the downward end of the conveying direction of the third conveying device relative to the first positioning plate and the second positioning plate.

[0012] Preferably, the feeding end is smoothly designed, and the unloading end is provided with an anti-slip pad.

[0013] Compared with the prior art, the advantages of this utility model are: (1) By setting up the flipping device, the panel can be flipped during the panel circulation process; when flipping, multiple flipping rods support the panel at the same time, which can prevent the panel from bending and deforming, and thus can be applied to the flipping of panel products of various sizes and specifications. In addition, the loading end of the flipping rod is smoothly designed so that the panel can slide along the loading end when it is lifted; the unloading end is designed to be non-slip so that the panel can avoid excessive displacement when it is flipped, which can ensure the position of the panel after flipping to a certain extent and facilitate accurate positioning at the positioning mechanism later. (2) Position the panels one by one through the positioning mechanism to ensure the accuracy of the position after transfer, thereby ensuring the accuracy of stacking. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1-8As shown, this utility model is applied to the flipping and stacking of plate-shaped products such as LCD panels and trays. When the panel is conveyed from the first conveying device to the flipping device, the flipping rod flips, and its loading end supports the panel, causing the panel to detach from the first conveying device. When flipped to approximately 90 degrees, the panel slides to the unloading end, is supported by the unloading end, and moves to the underside of the unloading end, placing the panel at the second conveying device. Driven by the second conveying device, the panel is conveyed to the third conveying device. At the third conveying device, the panel is blocked by a baffle and positioned by the first and second positioning plates. After positioning, the transfer device drives the suction cup assembly to pick up the panel and transfer it to the fourth or fifth conveying device for temporary storage. When the panels at the fourth or fifth conveying device are stacked to a certain height or quantity, they are conveyed and unloaded by the fourth or fifth conveying device. Specifically: A panel flipping and stacking device includes a flipping mechanism 1, a positioning mechanism 2, and a stacking mechanism 3.

[0017] The flipping mechanism 1 includes a first conveying device 11, a second conveying device 12, and a flipping device 13, with the flipping device 13 disposed between the first conveying device 11 and the second conveying device 12. The flipping device 13 includes a flipping rod 131 and a flipping drive device 132 for driving the flipping rod 131 to rotate.

[0018] In this embodiment, the flipping device 13 includes a rotating shaft 133, on which a flange 134 is fixedly connected. A flipping rod 131 is connected to the flange 134 in an outwardly extending radial direction. Multiple flanges 134 are provided, and multiple flipping rods 131 are connected to each flange 134. Each flipping rod 131 includes a loading end 1311 and a unloading end 1312. The loading end 1311 is smoothly arranged, and the unloading end 1312 is provided with an anti-slip pad 1313. When the flipping rod 131 rotates, it passes parallel to or at a small angle to the upper surfaces of the first conveying device 11 and the second conveying device 12 when it passes the upper surface of the first conveying device 11 upwards and the lower surface of the second conveying device 12 downwards. When the panel is flipped, the loading end 1311 supports the panel at the first conveying device 11. When the panel is flipped to a certain angle, it can slide along the loading end 1311, so that one side of the panel abuts against the edge of the flange 134. When the panel is flipped to about 90 degrees, it falls to the unloading end 1312 and is supported by the unloading end 1312. After continuing to rotate, the unloading end 1312 places the panel at the second conveying device 12. The anti-slip pad 1313 on the unloading end 1312 can provide cushioning and anti-slip when the panel falls to the unloading end 1312, avoiding excessive displacement of the panel and damage due to collision.

[0019] Both the first conveying device 11 and the second conveying device 12 are roller conveyors, and in the overlapping area with the flipping device 13, adjacent rollers of the first conveying device 11 and the second conveying device 12 are independent of each other, such as... Figure 3 As shown, each roller has a separate support rod 14 so that the flipping rod 131 can pass between the two rollers when rotating, avoiding interference between them.

[0020] Additionally, it should be noted that the rotation rhythm of the panel can be controlled by setting the rotation speed of the first transmission device 11 and the second transmission device 12, as well as by setting the length of the flipping device 13 in the transmission direction of the first transmission device 11 and the rotation speed, so that the flipping rod 131 flips one panel at a time, and avoids interference between the panel and the next set of flipping rods 131 after the flip.

[0021] The positioning mechanism 2 includes a third conveying device 21 and a first positioning plate 22 and a second positioning plate 23 disposed on both sides of the third conveying device 21, and a first bracket 26 connected to the first positioning plate 22 and the second positioning plate 23 respectively via a first slide rail 24 and a second slide rail 25. A first direct drive device 27 is connected to the first bracket 26, and the first direct drive device 27 is connected to the first positioning plate 22 and can drive the first positioning plate 22 to reciprocate on the first slide rail 24.

[0022] The first bracket 26 is also provided with two pulleys 28 and an annular belt connected by the two pulleys 28. The two pulleys 28 divide the annular belt 281 into two symmetrical parts, which are respectively connected to the first positioning plate 22 and the second positioning plate 23.

[0023] In this embodiment, the first slide rail 24 and the second slide rail 25 are parallel to each other. The two pulleys 28 separating the two parts of the annular belt 281 are also parallel to each other. When the first direct drive device 27 drives the first positioning plate 22 to move on the first slide rail 24, it drives the annular belt 281 to rotate on the two pulleys 28. Consequently, the two parallel parts of the annular belt 281 move in opposite directions, driving the second positioning plate 23 to move synchronously on the second slide rail 25, causing the first positioning plate 22 and the second positioning plate 23 to move closer or further apart synchronously. This completes the positioning of both sides of the panel.

[0024] In this embodiment, the positioning mechanism 2 further includes a baffle 29, which is disposed at the downward end of the conveying direction of the third conveying device 21 relative to the first positioning plate 22 and the second positioning plate 23. A first lifting device 291 is connected to the baffle 29, which can drive the baffle 29 to move in the vertical direction so that the baffle 29 extends or retracts on the surface of the third conveying device 21.

[0025] During positioning, the baffle 29 extends upward onto the upper surface of the third conveying device 21 under the drive of the first lifting device 291. When the panel is conveyed to the baffle 29 on the third conveying device 21, it is blocked by the baffle 29, completing the panel's positioning in the front-back direction. Then, under the drive of the first direct drive device 27, the first positioning plate 22 and the second positioning plate 23 move towards each other, abutting against the panel from both sides, completing the panel's positioning in the left-right direction. After positioning, the first positioning plate 22 and the second positioning plate 23 are reset under the drive of the first direct drive device 27 to facilitate the transfer of the stacking mechanism 3.

[0026] The stacking mechanism 3 includes a fourth conveying device 31, a suction cup assembly 32, and a transfer device 33 connected to the suction cup assembly 32. The suction cup assembly 32 picks up the panels on the third conveying device 21 and moves them to the fourth conveying device 31 for stacking under the drive of the transfer device 33. The suction cup assembly 32 is connected to the transfer device 33 via a second lifting device 34.

[0027] In this embodiment, a fifth conveying device 35 is arranged parallel to the fourth conveying device 31, and a transfer device 33 is simultaneously mounted across the fifth conveying device 35. The suction cup assembly 32 is equipped with multiple suction nozzles, and the relative positions of these nozzles can be adjusted to accommodate the picking up of panels of different sizes. Simultaneously, the use of multiple suction nozzles to pick up the panel helps to prevent significant deformation of the panel and ensures stable panel transport. When transferring the panel, the transfer device 33 drives the suction cup assembly 32 to directly above the panel at the third conveying device 21. The second lifting device 34 then drives the suction cup assembly 32 to pick up the panel downwards and lift it upwards. Subsequently, driven by the transfer device 33, the suction cup assembly 32 moves to directly above either the fourth conveying device 31 or the fifth conveying device 35, and is then driven downwards by the second lifting device 34 to place the panel at the fourth conveying device 31 or the fifth conveying device 35. When the number or height of the panels stacked on the fourth conveyor 31 or the fifth conveyor 35 reaches a certain level, the fourth conveyor 31 or the fifth conveyor 35 is activated to convey the stacked panels out.
