Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal panels, and more specifically, to an automatic alignment and full-size code reading mechanism for liquid crystal panels. Background Art

[0002] During the production process of liquid crystal panels, it is often necessary to read the system to display panel codes for classification or scrapping. In the existing mechanism, the placement position of the display panel is manually aligned, and the code reading position of the reading system is also fixed. It is impossible to perform full-size display panel code reading, and the code reading success rate is not high, resulting in a significant reduction in the production efficiency of liquid crystal panels.

[0003] In the existing mechanism, the display panel is placed on the platform, and the position of the clamping cylinder is manually adjusted according to the size of the display panel. For example, if the display panel is 55 inches, the clamping position is adjusted according to the size of the 55-inch display panel. Moreover, every time the size of the display panel is changed, the size needs to be adjusted once, which greatly reduces the production efficiency, and the alignment accuracy deviation is large. The positions of the codes of each type of display panel are different, and the existing fixed reading system cannot perform full-size display panel code reading. These disadvantages limit the production efficiency of liquid crystal panels.

[0004] Therefore, how to solve the problems of low alignment accuracy and inability to perform full-size code reading in the existing mechanism is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model

[0055] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0056] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0057] It should be noted that the orientation terms such as "upper" and "lower" below are defined based on the accompanying drawings of the specification.

[0058] The core of the present utility model is to provide an automatic alignment and full-size code reading mechanism for liquid crystal panels, which can improve the alignment accuracy and code reading accuracy of liquid crystal panels, and at the same time improve production capacity to meet the high-efficiency and high-quality requirements of liquid crystal panel production.

[0059] Please refer to Figure 1 、 Figure 2 and Figure 3 . An automatic alignment and full-size code reading mechanism for liquid crystal panels includes a frame 1, a sensing device 2 disposed at the central position of the frame 1 and used for sensing the display panel 01, and a control device. The sensing device 2 is signal-connected to the control device. When the sensing device 2 senses that the display panel 01 is in place, it sends a signal to the control device, and the control device controls the next action.

[0060] An automatic alignment mechanism 3 and a code reading mechanism 4 are provided inside the frame 1. The automatic alignment mechanism 3 includes two groups of positioning devices perpendicular to each other in a plane. The positioning devices move towards and away from the central position of the frame 1. The positioning devices are signal-connected to the control device. After the control device receives the signal that the display panel 01 is in place sent by the sensing device 2, it controls the positioning devices to move towards the central position of the frame 1 until the positioning devices are in contact with the display panel 01, so as to realize the positioning of the display panel 01 by the positioning devices. The positioning devices are devices that can move in two mutually perpendicular directions in a plane, and can be applicable to the precise positioning of display panels 01 of different sizes, so as to improve the application range.

[0061] The code reading mechanism 4 includes a scanning device 41 for scanning the code on the display panel 01 and a driving device for driving the scanning device 41 to move in two mutually perpendicular directions in a plane. The scanning device 41 and the driving device are both signal-connected to the control device. After the control device controls the positioning devices to position the display panel 01, it controls the driving device to operate to drive the scanning device 41 to move in two perpendicular directions in a plane. The code reading mechanism 4 is located above the automatic alignment mechanism 3, so as to realize the reading of the code at any position on the display panel 01 by the scanning device 41 and improve the code reading accuracy of the scanning device 41.

[0062] The automatic alignment and full-size code reading mechanism for liquid crystal panels arranged in the above manner can be applicable to the precise positioning and all-round code reading of display panels 01 of different sizes, improve the alignment accuracy and code reading accuracy, and do not require personnel to repeatedly debug, thereby improving production capacity and reducing labor costs.

[0063] In the above embodiments, an inlet for the manipulator to convey the display panel 01 is provided on one side of the frame 1. The manipulator is signal-connected to the control device. The frame 1 has a first mounting surface for setting the automatic alignment mechanism 3 and a second mounting surface for setting the code reading mechanism 4. A support structure 5 for placing the display panel 01 is further provided on the first mounting surface.

[0064] It should be noted that the manipulator is controlled by the control device to convey the display panel 01 from the inlet of the frame 1 to the support structure 5 on the first mounting surface. At the same time, after the sensing device 2 on the frame 1 senses that the display panel 01 is in place, it sends a signal to the control device. The control device controls the positioning device of the automatic alignment mechanism 3 to position the display panel 01 on the support structure 5. After the positioning is completed, the control device controls the scanning device 41 on the second mounting surface to read the code at any position on the display panel 01, improving the accuracy of code reading.

[0065] Please refer to Figure 4 , the support structure 5 includes a support column 51 fixed to the first mounting surface and a positioning member 52 provided at the upper end of the support column 51. The positioning member 52 is a spherical structure, and part of the positioning members 52 are rotatably connected to the support column 51.

[0066] It can be understood that part of the positioning members 52 are set as rotatable structures and are made of plastic parts to reduce the friction of the positioning members 52 on the display panel 01, and can also improve the support of the support structure 5 for the display panel 01. In this embodiment, the support column 51 is made of stainless steel to support the display panel 01. In practical applications, there are no restrictions on the specific structures, connection methods, materials, etc. of the support column 51 and the support members, as long as the above technical effects can be achieved.

[0067] Furthermore, one set of positioning devices is movably arranged along the X direction of the frame and is used to position the position of the display panel 01 along the Y direction of the frame 1. The positioning device includes two first clamping structures 31 symmetrically arranged on both sides of the first mounting surface. The first clamping structure 31 provided at the inlet of the frame 1 and below the first mounting surface also moves along the Z direction of the frame 1. The other set of positioning devices is movably arranged along the Y direction and is used to position the position of the display panel 01 along the X direction. The positioning device includes two second clamping structures 32 symmetrically arranged on both sides of the first mounting surface and perpendicular to the first clamping structure 31.

[0068] It should be noted that when the manipulator conveys the display panel 01 to the rack 1 under the control of the control device, the control device first controls the first clamping structure 31 located below the first mounting surface to move downward along the Z direction to below the inlet of the rack 1. Then, the display panel 01 is conveyed from the inlet to the support structure 5 through the manipulator. After the sensing device 2 senses that the display panel 01 is in place, it sends a signal to the control device. The control device controls the downward-moved first clamping structure 31 to first rise upward to a position flush with the display panel 01, and then controls the other first clamping structure 31 and the second clamping structure 32 to move along the X direction and the Y direction respectively to position the display panel 01 on the support structure 5 at the same time. After the positioning is completed, the control device controls the scanning device 41 on the second mounting surface to read the code at any position on the display panel 01 to improve the accuracy of code reading.

[0069] Please refer to Figure 5 , a first bottom plate 6 extending along the Y direction to the central position of the rack 1 is provided on the first mounting surface. The second clamping structure 32 is movably arranged on the first bottom plate 6. The second clamping structure 32 includes a reinforcing support 8 sliding along the first bottom plate 6. The reinforcing support 8 is driven by a first servo motor 9 connected to the control device. A first connecting rod 10 extending along the X direction is provided on the reinforcing support 8. A plurality of positioning blocks 11 for positioning the display panel 01 are provided at the bottom of the first connecting rod 10.

[0070] It can be understood that when the display panel 01 needs to be aligned, the control device controls the first servo motor 9 to operate to drive the reinforcing support 8 to move along the first bottom plate 6, so that the first connecting rod 10 and the reinforcing support 8 move synchronously along the Y direction. The side surface of the display panel 01 is positioned by the positioning blocks 11 arranged along the X direction at the bottom of the first connecting rod 10.

[0071] On the basis of the above embodiments, a first bottom plate 6 extending along the X direction to the central position of the rack 1 is provided on the first mounting surface. The first clamping structure 31 away from the inlet of the rack 1 is movably arranged on the first bottom plate 6. The first clamping structure 31 includes a reinforcing support 8 sliding along the first bottom plate 6. The reinforcing support 8 is driven by a second servo motor 12 connected to the control device. A second connecting rod 13 extending along the Y direction is provided on the reinforcing support 8. A plurality of positioning blocks 11 for positioning the display panel 01 are provided at the bottom of the second connecting rod 13.

[0072] It should be noted that when the display panel 01 needs to be aligned, the control device controls the second servo motor 12 to operate to drive the reinforcing support 8 to move along the first bottom plate 6, so that the second connecting rod 13 and the reinforcing support 8 move synchronously along the X direction. The side surface of the display panel 01 is positioned by the positioning blocks 11 arranged along the Y direction at the bottom of the second connecting rod 13.

[0073] Please refer toFigure 6 , a second bottom plate 14 extending along the X direction to the central position of the frame 1 is provided on the first mounting surface. The first clamping structure 31 at the entrance of the frame 1 is movably arranged on the second bottom plate 14. The first clamping structure 31 includes a mounting plate 15 sliding along the second bottom plate 14 and a third servo motor 16 for driving the mounting plate 15 to slide. A support frame 17 moving along the Z direction is provided on the mounting plate 15. The support frame 17 is driven by a lifting cylinder 18 connected to the control device. A second connecting rod 13 extending along the Y direction is provided on the support frame 17. A plurality of positioning blocks 11 for positioning the display panel 01 are provided at the bottom of the second connecting rod 13.

[0074] It can be understood that when the manipulator conveys the display panel 01 to the frame 1 under the control of the control device, the control device first controls the lifting cylinder 18 to operate to drive the support frame 17 to move downward along the Z direction to below the entrance of the frame 1. Then, the display panel 01 is conveyed from the entrance to the support structure 5 through the manipulator. After the sensing device 2 senses that the display panel 01 is in place, it sends a signal to the control device. The control device controls the lifting cylinder 18 to operate to drive the support frame 17 to move upward along the Z direction to a position flush with the display panel 01. Then, the first servo motor 9, the second servo motor 12, and the third servo motor 16 are controlled to operate synchronously so that both the mounting plate 15 and the reinforcement support 8 move toward the position close to the display panel 01, and the positioning blocks 11 on the first connecting rod 10 and the second connecting rod 13 position the display panel 01 on the support structure 5. After the positioning is completed, the control device controls the scanning device 41 on the second mounting surface to read the code at any position on the display panel 01, improving the accuracy of code reading.

[0075] As a preferred embodiment, slide rail assemblies 7 are provided on both the first bottom plate 6 and the second bottom plate 14, and a guiding assembly 19 extending along the Z direction is provided on the support frame 17.

[0076] It should be noted that by providing the guiding assembly 19, it is ensured that the support frame 17 can move along the Z direction, preventing the support frame 17 from shifting during the up and down movement along the Z direction and ensuring the accuracy of aligning with the display panel 01. There is no limitation on the specific structure of the guiding assembly 19.

[0077] Among them, slide rail assemblies 7 are provided on the first bottom plate 6 and the second bottom plate 14 so that the reinforcement support 8 and the mounting plate 15 can slide smoothly. In this embodiment, the slide rail assembly 7 includes a slide rail and a slider. The slide rail is provided on the first bottom plate 6 and the second bottom plate 14, and the slider moves along the slide rail. The corresponding reinforcement support 8 and mounting plate 15 are provided on the slider. However, in practical applications, there is no limitation on this as long as the above technical effects can be achieved.

[0078] Please refer to Figure 7, the positioning block 11 is connected to the first connecting rod 10 and the second connecting rod 13 through a connecting shaft 20. A bearing is provided inside the positioning block 11 to enable the positioning block 11 to be rotatably connected to the connecting shaft 20.

[0079] It can be understood that by providing a bearing inside the positioning block 11, the rotatable connection between the positioning block 11 and the first connecting rod 10 and the second connecting rod 13 is realized.

[0080] Please refer to Figure 8 and Figure 9 , the driving device includes a first driving module 42 provided on the second mounting surface and a second driving module 43 movably provided on the first driving module 42. The first driving module 42 extends along the X direction, the second driving module 43 extends along the Y direction, and the scanning device 41 is movably provided on the second driving module 43.

[0081] It should be noted that the first driving module 42 is driven by a fourth servo motor 21 signal-connected to the control device, and the second driving module 43 is driven by a fifth servo motor 22 signal-connected to the control device. When it is necessary to read the code on the display panel 01, the control device controls the fourth servo motor 21 to operate to drive the second driving module 43 to move along the first driving module 42, thereby driving the scanning device 41 on the second driving module 43 to move along the X direction. The control device controls the fifth servo motor 22 to operate to drive the scanning device 41 to move along the second driving module 43, that is, along the Y direction, so that the movement of the scanning device 41 in the X direction and the Y direction can be realized, and thus the code reading of the entire size of the display panel 01 by the scanning device 41 can be realized.

[0082] In this embodiment, the size of the display panel 01 is smaller than the maximum travel that the scanning device 41 can move in the X direction and the Y direction. The scanning device 41 is a code reading camera. In practical applications, there is no limitation on the specific type of the scanning device 41, as long as the above technical effects can be achieved.

[0083] In summary, for the automatic alignment and full-size code reading mechanism of the liquid crystal panel provided by the present utility model, when the manipulator is ready to send the display panel 01 in, the control device controls the lifting cylinder 18 to descend to the standby position and wait for the manipulator to complete the film placement. After the manipulator finishes placing the film, the lifting cylinder 18 rises to the jacking position. The first connecting rod 10 in the X direction and the second connecting rod 13 in the Y direction advance and clamp the display panel 01 under the control of the control device. When switching the size of the display panel 01, only need to create a new size of the display panel 01 in advance and input the size of the display panel 01 in the control device to complete the cutting. Since it is driven by four independent servo motors, when there is a deviation in the size of the display panel 01, only by changing the position of the servo motor on one side can the unilateral compensation correction be achieved. After the display panel 01 completes the automatic alignment, the scanning device 41 moves along the X direction and the Y direction to the code reading position to complete the code reading. Compared with the original manually adjusted mechanism, the speed, alignment accuracy and cutting time have been significantly improved. Compared with the fixed code reading mechanism, the present application can read the code at any position within the range of the maximum code reading position.

[0084] The positioning device can greatly improve the cutting time, increase the production capacity, improve the alignment accuracy, facilitate the operation of personnel. The scanning device 41 can read the code at any position of the display panel 01, improve the code reading accuracy, and eliminate the need for personnel to repeatedly debug, thereby increasing the production capacity to meet the high-efficiency and high-quality requirements of the production of the display panel 01 and reducing the labor cost.
