Description

Technical Field

[0001] This utility model belongs to the field of liquid crystal panel manufacturing technology, and specifically relates to a liquid crystal panel flipping device. Background Technology

[0002] In the production of LCD panels, the panels often need to be flipped due to process requirements. Currently, the industry commonly uses double-sided clamping or single-sided suction flipping methods, such as using upper and lower double-sided suction cups to clamp the panel, with the transmission unit flipping the panel synchronously. These flipping mechanisms are complex and inefficient. In case of malfunctions, the operation cannot be stopped independently; only maintenance is possible, during which production cannot continue. Furthermore, existing clamping methods pose a high quality risk, leading to cleaning problems after the LCD panel breaks. Therefore, a new type of LCD panel flipping device is needed. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, this utility model provides a liquid crystal panel flipping device. The technical problem to be solved by this utility model is achieved through the following technical solution:

[0004] This utility model provides a liquid crystal panel flipping device, including: a flipping mechanism, a movable slide, and a flipping motor; wherein, two flipping mechanisms are arranged opposite to each other, and the two flipping mechanisms are slidably connected to the movable slide, and the distance between the two flipping mechanisms is adjustable; each flipping mechanism is connected to the flipping motor and rotates independently under the drive of the flipping motor; each flipping mechanism is provided with a plurality of fan-shaped wheels, and a plurality of slots are formed between any two adjacent fan-shaped wheels, and a plurality of suction cups are provided in each slot; the liquid crystal panel is clamped between the two flipping mechanisms arranged opposite to each other.

[0005] In one embodiment of the present invention, each of the suction cups is connected to an external air supply device via an air pipe to create a negative pressure on the suction cup.

[0006] In one embodiment of this utility model, each slot of the flipping mechanism is covered with a soft material.

[0007] In one embodiment of this utility model, the soft material is disposed on both sides and the bottom of the groove.

[0008] In one embodiment of this utility model, the output shaft of the flipping motor is connected to the rotating shaft of the flipping mechanism via a belt pulley, and several of the fan-shaped wheels can be detachably connected to the rotating shaft.

[0009] In one embodiment of this utility model, a photoelectric sensor is provided on the outside of the slot of each of the flipping mechanisms, and the photoelectric sensors on two flipping mechanisms arranged opposite each other trigger each other.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model discloses a liquid crystal panel flipping device, in which two flipping mechanisms are arranged opposite each other. Each flipping mechanism is equipped with several sector-shaped wheels, and the liquid crystal panel is held in place by the slots formed between adjacent sector-shaped wheels and suction cups. The two flipping mechanisms are driven by independent flipping motors. Because the two flipping mechanisms are designed without a shaft connection, if one slot fails, another slot can be used to continue working. Setting up multiple sets of slots can not only temporarily store multiple liquid crystal panels to improve work efficiency, but also achieve liquid crystal panel flipping through small-angle rotation, reducing the risk of panel breakage and improving flipping efficiency.

[0021] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following detailed description of a liquid crystal panel flipping device according to this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] The foregoing and other technical contents, features, and effects of this utility model will be clearly presented in the following detailed description of the specific embodiments with reference to the accompanying drawings. Through the description of the specific embodiments, a more in-depth and specific understanding can be gained of the technical means and effects adopted by this utility model to achieve the intended purpose. However, the accompanying drawings are only provided for reference and illustration and are not intended to limit the technical solution of this utility model.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of a liquid crystal panel flipping device provided in an embodiment of the present invention; Figure 2 This is a schematic diagram of the flipping mechanism provided in an embodiment of the present invention.

[0025] This utility model provides a liquid crystal panel flipping device, including: a flipping mechanism 1, a movable slide 2, and a flipping motor 3; wherein, two flipping mechanisms 1 are arranged opposite to each other, and the two flipping mechanisms 1 are slidably connected to the movable slide 2 respectively, and the distance between the two flipping mechanisms 1 is adjustable; each flipping mechanism 1 is connected to a flipping motor 3 and rotates independently under the drive of the flipping motor 3; each flipping mechanism 1 is provided with a plurality of fan-shaped wheels 11, and a plurality of slots are formed between any two adjacent fan-shaped wheels 11, and a plurality of suction cups 12 are provided in each slot; the liquid crystal panel 10 is clamped between the two flipping mechanisms 1 arranged opposite to each other.

[0026] It is worth noting that, since the liquid crystal panels 10 required for actual production have different widths, in order to improve the adaptability of the liquid crystal panel flipping device in this embodiment, the two flipping mechanisms 1 are slidably connected to the moving slide 2 respectively. The two flipping mechanisms 1 can move relative to each other or in opposite directions on the moving slide 2, so that the axial distance between the two flipping mechanisms 1 can be adjusted.

[0027] like Figure 3 and Figure 4 As shown, Figure 3 This is a partial structural schematic diagram of the flipping mechanism provided in an embodiment of the present utility model; Figure 4This is a partial structural schematic diagram of the suction cup provided in an embodiment of the present invention.

[0028] In an optional embodiment, each suction cup 12 is connected to an external air supply device via an air pipe to create negative pressure on the suction cup 12, and the liquid crystal panel 10 is adsorbed by the negative pressure to achieve stable flipping. At the same time, to prevent the liquid crystal panel 10 from breaking, each slot of the flipping mechanism 1 is covered with a soft material 13.

[0029] For example, the flexible material 13 is disposed on both sides and the bottom of the slot. Specifically, the flexible material 13 is disposed on one side of the suction cup 12, surrounding several suction cups 12, and also covers the opposite side of the suction cup 12 and is disposed at the bottom of the slot, so as to provide cushioning when the liquid crystal panel 10 comes into contact with the slot, thereby reducing the risk of breakage of the liquid crystal panel 10.

[0030] For example, the soft material 13 may be made of silicone, rubber or similar materials with cushioning effect.

[0031] In an optional embodiment, the output shaft of the flipping motor 3 is connected to the rotating shaft of the flipping mechanism 1 via a belt pulley drive, and several fan-shaped wheels 11 can be detachably connected to the rotating shaft.

[0032] like Figure 5 As shown, Figure 5 This is a schematic diagram of the operation of the through-beam photoelectric sensor provided in this embodiment of the present invention.

[0033] In an optional embodiment, a photoelectric sensor 4 is provided on the outside of the slot of each flipping mechanism 1, and the photoelectric sensors 4 on two flipping mechanisms 1 arranged opposite each other trigger each other.

[0034] For example, photoelectric sensors 41 and 42 trigger each other to determine the slot position between the two flipping mechanisms 1. When the slots of the two flipping mechanisms 1 are aligned, the LCD panel 10 is fed into the corresponding slot of the two flipping mechanisms 1. When the slots of the two flipping mechanisms 1 are not aligned, the flipping mechanism 1 is driven to rotate by the flipping motor 3, and it is then determined whether the photoelectric sensors 41 and 42 or 43 can trigger each other, and gradually adjusted to alignment. In addition, when one or more slots of one flipping mechanism 1 malfunction, since the two flipping mechanisms 1 rotate independently under the drive of the flipping motor 3, it is only necessary to disable the malfunctioning slot of one flipping mechanism 1, rotate to the next slot, and align it with the photoelectric sensor 4 to achieve continuous production. Alternatively, the two flipping mechanisms 1 can be rotated at different angles to achieve slot alignment. Conversely, if the two flipping mechanisms 1 are coaxially arranged, when the slot of one flipping mechanism 1 malfunctions, the corresponding slot on the other flipping mechanism 1 also becomes unusable, resulting in a waste of production resources.

[0035] It is worth noting that several slots are formed by several fan-shaped wheel pieces 11, and each slot can hold a liquid crystal panel 10. If a total of 10 flip slots are provided on the two flip mechanisms 1, the flipping efficiency is increased to 5 times compared with the traditional double-sided clamping flipping device, while the wear rate of the mechanism is only 1 / 5 of that of the traditional double-sided clamping flipping device.

[0036] like Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of the operation of the liquid crystal panel flipping device provided in this embodiment of the utility model; Figure 7 This is a flowchart illustrating the operation of the liquid crystal panel flipping device provided in this embodiment of the utility model.

[0037] The working principle of the LCD panel flipping device in this embodiment is as follows:

[0038] Based on the size of the LCD panel 10, the distance between the two flipping mechanisms 1 is adjusted by the movable slide 2, and then the two flipping mechanisms 1 are driven to rotate synchronously by their respective flipping motors 3. The photoelectric sensors 4 at the corresponding slot positions of the two flipping mechanisms 1 are triggered to ensure that the slots of the two flipping mechanisms 1 are aligned with each other. Next, the LCD panel 10 is fed onto the conveying mechanism from one side of the two flipping mechanisms 1, and is attracted and fixed by the suction cups 12 at the corresponding slots of the two flipping mechanisms 1. As the two flipping mechanisms 1 continue to rotate, they are flipped from 0° to 180°. After flipping, the suction cups 12 break the vacuum, and the flipped LCD panel 10 is collected and discharged by the conveying mechanism. For example, the conveying mechanism can be a conveyor belt or a roller drive mechanism, and this embodiment does not limit it to this.

[0039] In addition, when the LCD panel 10 does not need to be flipped, the distance between the two flipping mechanisms 1 can be adjusted by moving the slide table 2, and the operation of the flipping motor 3 can be stopped at the same time. The LCD panel 10 can be freely fed and discharged by the conveying mechanism.

[0040] When one or more slots of one of the flipping mechanisms 1 malfunction, since both flipping mechanisms 1 are driven by independent flipping motors 3 and are designed without coupling, one flipping mechanism 1 can be driven to rotate independently by the flipping motor 3. Then, the photoelectric sensor 4 at the corresponding slot position ensures that the adjusted slots are aligned with each other, thus guaranteeing the normal operation of the LCD panel flipping device. In other words, by using independent flipping motors 3 and photoelectric sensors 4 for alignment, only a few slots need to be disabled to ensure the overall normal operation of the LCD panel flipping device. When some slots malfunction, there is no need to stop for maintenance, enabling continuous production.

[0041] Furthermore, after continuous operation, each slot of the two flipping mechanisms 1 can store one LCD panel 10. Multiple slots provide temporary storage space for the LCD panels 10. When unloading is required, flipping can be achieved by rotating at a small angle, improving work efficiency. Compared with the traditional scheme where the transmission unit and the clamped LCD panel flip together synchronously, the small-angle rotation is more stable, which helps to reduce the occurrence of LCD panel breakage and also reduces cleaning problems caused by breakage.

[0042] This utility model discloses a liquid crystal panel flipping device, in which two flipping mechanisms are arranged opposite each other. Each flipping mechanism is equipped with several sector-shaped wheels, and the liquid crystal panel is held in place by the slots formed between adjacent sector-shaped wheels and suction cups. The two flipping mechanisms are driven by independent flipping motors. Because the two flipping mechanisms are designed without a shaft connection, if one slot fails, another slot can be used to continue working. Setting up multiple sets of slots can not only temporarily store multiple liquid crystal panels to improve work efficiency, but also achieve liquid crystal panel flipping through small-angle rotation, reducing the risk of panel breakage and improving flipping efficiency.
