Description

Technical Field

[0001] This utility model relates to the technical field of the panel industry, specifically to a flipping mechanism with calibration function for panels. Background Technology

[0002] In the production process of display panels, panels frequently need to be handled and transported to various processes. Furthermore, panel flipping is often required, both during the inspection process and in general. Typically, panel flipping involves operators moving the panel to a flipping machine, which then flips it; alternatively, a robot can place the panel on a support platform, and the flipping machine picks it up and rotates it. However, these flipping machines lack calibration capabilities and cannot accurately grasp and flip the panel. They often only perform position detection after flipping, which increases the CT (cut-off) time in the panel production process, thus impacting production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a flipping mechanism with calibration function for a panel, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a panel flipping mechanism with calibration function, comprising a fixed frame, on which a vertically arranged lifting module is mounted, the lifting module is connected to a mounting base, the mounting base is connected to a flipping structure, and a calibration structure is provided below the flipping structure; the flipping structure includes a hollow rotating platform capable of rotating along a horizontal axis, the hollow rotating platform is connected to a flipping servo motor for driving its rotation, the hollow shaft of the hollow rotating platform is connected to a mounting bracket, and the mounting bracket is provided with a plurality of suction cups; the calibration structure includes a calibration platform, the calibration platform is provided with a plurality of panel support columns, and the calibration platform is provided with a plurality of first calibration components and a plurality of second calibration components.

[0005] Further optimization involves arranging several suction cups in two rows, symmetrically positioned on two opposite sides of the mounting bracket, to ensure effective adsorption of the panel.

[0006] Further optimization involves using a vacuum corrugated suction cup, which provides cushioning and shock absorption, protecting the panel and preventing damage.

[0007] Further optimization involves providing several mounting plates on the mounting bracket. Each mounting plate is positioned on the side of the mounting bracket where the suction cups are located. Each mounting plate is equipped with an adjustable sensor to detect whether the suction cups are adsorbing onto the panel.

[0008] Further optimization involves arranging several panel support columns in a rectangular array, with the upper end of each support column featuring a spherical structure design. This reduces the contact area between the support column and the panel, minimizing friction and preventing damage to the panel.

[0009] Further optimization involves providing ceramic balls at the upper end of the panel support column, which have extremely high hardness and wear resistance, effectively resisting wear caused by frequent contact or friction.

[0010] Further optimization involves having four first calibration components symmetrically arranged on two opposite sides of the calibration platform, and two second calibration components symmetrically arranged on the same platform. The calibration direction of the second calibration components is perpendicular to that of the first calibration components. The first calibration components are used to calibrate the left-right position of the panel, and the second calibration components are used to calibrate the front-back position of the panel.

[0011] Further optimization involves the first calibration component comprising a first adjusting cylinder. A mounting block is connected to the piston rod end of the first adjusting cylinder. An adjusting plate is mounted on the mounting block, and a first idler wheel is mounted on the adjusting plate. The first adjusting cylinder drives the mounting block to move the adjusting plate and the first idler wheel left and right, thereby moving the panel left and right and calibrating its left and right position.

[0012] Further optimization involves providing a rectangular groove on the mounting block for adjusting the position of the adjustment plate, facilitating the installation and position adjustment of the adjustment plate.

[0013] Further optimization involves the second calibration component comprising a second adjusting cylinder. An L-shaped fixing plate is connected to the piston rod end of the second adjusting cylinder, and a second idler wheel is mounted on the fixing plate. The extension / retraction direction of the piston rod of the second adjusting cylinder is perpendicular to the extension / retraction direction of the piston rod of the first adjusting cylinder. The second adjusting cylinder can drive the fixing plate and the second idler wheel to move back and forth, thereby calibrating the front-to-back position of the panel.

[0014] Beneficial effects: The panel of this utility model uses a flipping mechanism with calibration function. The calibration structure realizes the position calibration of the panel to ensure that the panel is centered. Through the cooperation of the lifting module and the flipping structure, the panel is attracted and flipped, and the panel can be flipped 180°. Specifically, the first calibration component realizes the left and right centering of the panel, and the second calibration component realizes the front and back centering of the panel, and finally realizes the centering adjustment of the panel to ensure that the panel is located in the center position of the calibration platform. The flipping servo motor drives the hollow rotating platform to rotate, which drives the mounting bracket to rotate 180°, so as to flip the panel held by the suction cup by 180°.

[0015] The flipping mechanism has a simple structure, is easy to operate, and has precise panel position calibration, ensuring accurate adsorption of the panel by the flipping mechanism and accurate panel position after flipping. Furthermore, the panel position is already calibrated when the flipping mechanism adsorbs the panel, effectively saving process CT time and improving the work efficiency of panel production.

Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figure 1-4 , Figure 6As shown, a panel flipping mechanism with calibration function includes a fixed frame 1, on which a vertically arranged lifting module 2 is mounted. The lifting module 2 is connected to a mounting base 5, and the mounting base 5 is connected to a flipping structure 3. A calibration structure 4 is provided below the flipping structure 3. The flipping structure 3 includes a hollow rotating platform 31 that can rotate along a horizontal axis. The hollow rotating platform 31 is connected to a flipping servo motor 32 for driving its rotation. The hollow shaft of the hollow rotating platform 31 is connected to a mounting bracket 33, and the mounting bracket 33 is provided with a plurality of suction cups 34. The calibration structure 4 includes a calibration platform 41, on which a plurality of panel support columns 42 are provided. The calibration platform 41 is provided with a plurality of first calibration components 43 and a plurality of second calibration components 44.

[0026] In this application, the flipping mechanism is used for panel calibration and flipping, achieving a 180° flip of the panel. The panel is accurately positioned before and after the flip. The fixing frame 1 is used to install the lifting module 2, which drives the flipping structure 3 to rise and fall. This facilitates the descent of the flipping structure 3 to hold the panel, and also allows the flipping structure 3 to rise to a certain height to flip the panel. Simultaneously, it can raise the panel to a set height for easy transfer to the next workstation. The calibration structure 4 is used to calibrate the panel, ensuring it is centered within the calibration structure 4, thus guaranteeing accurate panel holding by the flipping structure 3. This saves CT time in the panel production process and improves panel production efficiency.

[0027] Specifically, the flipping structure 3 includes a hollow rotating platform 31, a flipping servo motor 32, a mounting bracket 33, and a suction cup 34. The flipping servo motor 32 drives the hollow shaft of the hollow rotating platform 31 to rotate, causing the mounting bracket 33 to rotate 180°, thus flipping the panel attached to the mounting bracket 33 by the suction cup 34 180° so that the top of the panel faces downwards. The calibration structure 4 includes a calibration platform 41, a panel support column 42, a first calibration component 43, and a second calibration component 44. The calibration platform 41 is used to install the panel support column 42, the first calibration component 43, and the second calibration component 44. The panel support column 42 supports the panel, and the first calibration component 43 and the second calibration component 44 adjust and calibrate the left-right and front-back positions of the panel, ensuring that the panel is centered on the calibration platform 41, thus calibrating the panel's position. At the same time, it ensures that the flipping structure 3 can accurately attach the panel, ensuring the accurate position of the panel after flipping.

[0028] Please refer to Figure 2 , Figure 3 As shown, in one embodiment of this application, a plurality of suction cups 34 are arranged in two rows and symmetrically on two opposite sides of the mounting bracket 33, which can simultaneously adsorb the two opposite sides of the panel, ensuring a firm adsorption of the panel and ensuring that the panel can be flipped smoothly and safely.

[0029] Furthermore, suction cup 34 is a vacuum corrugated suction cup. The corrugations on the edge of the suction cup can stretch and deform to fit irregular surfaces such as concave and convex surfaces and curved surfaces, compensate for small height differences, avoid air leakage, and handle uneven and curved workpieces. It has a buffering effect on sensitive workpieces such as panels, and also has a shock absorption effect to protect the panel and prevent it from being damaged.

[0030] Please refer to Figure 3 As shown, in another embodiment of this application, the mounting bracket 33 is provided with a plurality of mounting plates 35, the mounting plates 35 are disposed on the side of the mounting bracket 33 where the suction cup 34 is provided, and each mounting plate 35 is provided with a position-adjustable sensor 36.

[0031] In this embodiment, the sensor 36 is installed by setting the mounting plate 35. The sensor 36 detects the adsorption of the panel by the suction cup 34, ensuring the accurate adsorption of the panel by the flip structure 3 and sensing whether the suction cup 34 adsorbs the panel.

[0032] In this embodiment, there are two mounting plates 35, which are respectively located on the opposite outer sides of the two rows of suction cups 34, ensuring that both rows of suction cups 34 can adhere to the panel during adsorption, thus ensuring that the panel is firmly and stably adsorbed.

[0033] Please refer to Figure 1 , Figure 4-6 As shown, in another embodiment of this application, a plurality of panel support columns 42 are arranged in a rectangular array, and the upper end of the panel support columns 42 adopts a spherical structure design.

[0034] In this embodiment, the rectangular array of panel support columns 42 ensures stable support for the panel, guaranteeing stable placement of the panel on the calibration stage 41. The upper surface of the spherical panel support columns 42 reduces the contact area between the panel support columns 42 and the panel, reducing friction and preventing damage to the panel.

[0035] Furthermore, the upper end of the panel support column 42 is provided with a ceramic ball 421. The ceramic material has extremely high hardness and wear resistance, which can effectively resist wear caused by frequent contact or friction. The ceramic ball 421 can withstand repeated positioning contact of the panel and extend its service life; it can reduce adhesion or scratches on the contact surface with the panel and ensure high-precision positioning.

[0036] Please refer to Figure 1 , Figure 4 and Figure 6As shown, in another embodiment of this application, there are four first calibration components 43 symmetrically arranged on two opposite sides of the calibration platform 41, and two second calibration components 44 symmetrically arranged on two opposite sides of the calibration platform 41. The calibration direction of the second calibration components 44 is perpendicular to the calibration direction of the first calibration components 43.

[0037] In this embodiment, the first calibration component 43 is used to calibrate the left-right position of the panel, and the second calibration component 44 is used to calibrate the front-back position of the panel. Four symmetrically arranged first calibration components 43 are distributed on the left and right sides of the calibration platform 41 to calibrate and adjust the panel's left-right position, ensuring the panel is centered in the left-right position. Two symmetrically arranged second calibration components 44 are used to calibrate and adjust the panel's front-back position, ensuring the panel is centered in the front-back position. Therefore, the left-right and front-back positions of the panel are calibrated using four first calibration components 43 and two second calibration components 44, ensuring the panel is located at the center of the calibration platform 41.

[0038] Furthermore, the first calibration component 43 includes a first adjusting cylinder 431, the piston rod end of the first adjusting cylinder 431 is connected to a mounting block 432, the mounting block 432 is provided with an adjusting plate 433, and a first idler wheel 434 is mounted on the adjusting plate 433.

[0039] The first adjusting cylinder 431 drives the mounting block 432 to move left and right. The mounting block 432 is used to install the adjusting plate 433 and its position is adjustable. The adjusting plate 433 is used to rotate the first idler wheel 434, which abuts against the panel. When the first adjusting cylinder 431 pushes the mounting block 432 to move left and right, it can drive the adjusting plate 433 and the first idler wheel 434 on it to move synchronously. The left and right movement of the first idler wheel 434 pushes the panel placed on the panel support column 43 to move slightly left and right, thereby achieving left and right centering adjustment of the panel. Through the line contact between the first idler wheel 434 and the panel, the contact area between the first idler wheel 434 and the panel can be reduced, reducing friction and protecting the panel. At the same time, when the panel is adjusted back and forth, the first idler wheel 434 can roll along the edge of the panel, reducing friction and reducing the resistance of the panel during back and forth alignment.

[0040] Further optimization involves providing a rectangular groove on the mounting block 432 for adjusting the position of the adjusting plate 433. The adjusting plate 433 is installed in the rectangular groove of the mounting block 432 and can move left and right along the rectangular groove to adjust the installation position of the adjusting plate 433 left and right, thereby adjusting the installation position of the first idler wheel 434.

[0041] Furthermore, the second calibration assembly 44 includes a second adjusting cylinder 441, the piston rod end of the second adjusting cylinder 441 is connected to an L-shaped fixing plate 442, a second idler wheel 443 is mounted on the fixing plate 442, and the extension and retraction direction of the piston rod of the second adjusting cylinder 441 is perpendicular to the extension and retraction direction of the piston rod of the first adjusting cylinder 431.

[0042] The second adjusting cylinder 441 drives the fixed plate 442 to move back and forth. The fixed plate 442 is used to mount the second idler wheel 443. The left and right extension and retraction of the piston rod of the second adjusting cylinder 441 drives the fixed plate 442 to move back and forth, thereby driving the second idler wheel 443 to move back and forth. The back and forth movement of the second idler wheel 443 enables fine adjustment of the front and back position of the panel on the panel support column 42, achieving front and back centering adjustment of the panel. The second idler wheel 443 and the first idler wheel 434 have the same structure, both having line contact with the panel to reduce friction and reduce resistance to the left and right and front and back movement of the panel, facilitating the calibration and adjustment of the panel.

[0043] The L-shaped fixing plate 442 allows the second adjusting cylinder 441 to be set on the left and right sides of the calibration platform 41, and installed on the same side as the first adjusting cylinder 431, which can greatly reduce the area of ​​the calibration platform 41.

[0044] In this application, the working process of the flipping mechanism is as follows: the panel is placed on the calibration platform 41 by an external handling mechanism, and then the first calibration component 43 and the second calibration component 44 are activated. The first idler wheel 434 is driven to move left and right by the first adjusting cylinder 431, and the second idler wheel 443 is driven to move back and forth by the second adjusting cylinder 441, so as to center the position of the panel on the calibration platform 41; the flipping structure 3 is driven to move downward by the lifting module 2, and then the panel is picked up by the suction cup 34. The lifting module 2 drives the flipping structure 3 to move upward to the set height. The flipping servo motor 32 of the flipping structure 3 drives the hollow rotating platform 31 to operate. The hollow rotating platform 31 drives the mounting bracket 33 to rotate 180°, and flips the panel picked up by the suction cup 34 by 180°.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
