Description

Technical Field

[0001] This utility model relates to the field of liquid crystal panel conveying technology, and more specifically, to a multi-panel flip conveying mechanism. Background Technology

[0002] During the production of LCD panels, various tests are required, often involving flipping the panels to meet the demands of different testing items or equipment. However, existing technologies present several challenges in the LCD panel transport and flipping process.

[0003] On the one hand, the lack of integrated automated conveying and flipping devices means that the processes of panel gripping, positioning, flipping and receiving often require multiple independent devices or manual assistance. The poor coordination between these processes results in low overall conveying efficiency, making it difficult to meet the high efficiency requirements of large-scale production.

[0004] On the other hand, existing technologies struggle to achieve high-precision panel positioning. Inaccurate panel positioning not only affects the subsequent gripping of the panel by the flipping assembly, reducing the success rate and stability of gripping, but may also lead to panel misalignment or damage during the flipping process, impacting product quality.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a multi-panel flip-plate conveyor mechanism to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A multi-panel flip conveyor mechanism includes: a worktable; a robotic suction cup assembly located at one end of the worktable; a panel positioning assembly located at the top of one end of the worktable; a panel flipping assembly located inside one end of the worktable; a panel receiving seat located at the top center of the worktable; and a control box located at the center of one side of the worktable. The top of the panel receiving seat has several grooves that cooperate with the support rods.

[0009] To achieve panel positioning and installation, multiple positioning rods, driven by a drive motor, center and position the panel, facilitating subsequent panel flipping assembly's gripping of the panel. This ensures positioning accuracy and operational stability while automating operation to reduce manual intervention. The panel positioning assembly includes a support platform at one end of the worktable. The top of the support platform has several evenly arranged panel placement slots. The support platform's interior has several first chambers, each with through holes penetrating the panel placement slots at its top. A centering element is installed inside each of the first chambers. The centering element includes components located at the... A disc inside a chamber has several slide rails at its bottom and sliders at the top of the slide rails. A drive motor is located at the bottom of the disc, which is also located at the bottom of a support platform. The output shaft of the drive motor passes through the bottom of the first chamber and is fixedly connected to the disc. A positioning rod is located at one end of the top of the slider, and a first fixed shaft is located at the other end of the top of the slider. Several second fixed shafts are located on the outer side of the top of the disc. Two sets of symmetrical second fixed shafts are connected to two sets of symmetrical first fixed shafts via a first connecting rod, and the other two sets of symmetrical second fixed shafts are connected to the other two sets of symmetrical first fixed shafts via a second connecting rod.

[0010] To achieve panel flipping, an electric telescopic rod and telescopic columns drive a support plate for precise lifting and lowering, which, in conjunction with a servo motor-driven rotating shaft, enables high-precision panel flipping. The support rod on the outside of the rotating shaft uses suction cups to stably hold the panel, preventing damage during flipping. A quick-release structure consisting of springs, inserts, and limit grooves allows for easy disassembly and adjustment, improving maintenance efficiency. The panel flipping assembly includes a support plate located inside one end of the worktable. Telescopic columns are located at the four corners of the bottom of the support plate, and an electric telescopic rod is located in the center of the bottom of the support plate. Support seats are located at both ends of the top of the support plate, and a rotating shaft runs through the top of the side wall of each support seat. A servo motor connected to the support seat is located at one end of the rotating shaft, and the output shaft of the servo motor is fixedly connected to one end of the rotating shaft. The outer side of the shaft is provided with several evenly arranged support rods, and the top of each support rod is provided with several suction cups; the outer side of the shaft is provided with several mounting grooves that mate with the support rods, and the side walls of each mounting groove are provided with insertion holes; a second chamber is provided inside one end of the support rod, and a movable plate is provided at the bottom of the second chamber. Several springs are provided at one end of the movable plate, and the top of the movable plate is provided with insertion blocks that penetrate the side walls of the support rod and mate with the insertion holes on both sides; a connecting rod is provided at the middle of the top of the movable plate that penetrates the top of the support rod, and a sliding plate is provided at the top of the connecting rod; the top of the movable plate is symmetrically provided with limit grooves; a limit post that mates with the limit groove is provided at one end of the top of the insertion block; the distance between the two sets of limit grooves gradually increases along the direction closer to the spring.

By integrating a robotic suction cup assembly, a panel positioning assembly, a panel flipping assembly, and a panel receiving base, it forms a fully automated and collaborative operation of grasping, positioning, flipping, and receiving, which effectively improves the efficiency and accuracy of multi-panel conveying, positioning, flipping, and receiving.

[0013] 2. By setting up a panel positioning component, the panel can be positioned and installed. Driven by the drive motor, multiple positioning rods can be driven to center and position the panel, which facilitates the subsequent panel flipping component to grasp the panel. This ensures both positioning accuracy and operational stability, and also achieves automated operation to reduce manual intervention.

[0014] 3. By setting up a panel flipping component, the panel can be flipped. The electric telescopic rod and telescopic column drive the support plate to rise and fall precisely, and the servo motor drives the rotating shaft to achieve high-precision flipping of the panel.

[0024] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a multi-panel flip-up conveyor mechanism is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, the multi-panel flip conveyor mechanism according to an embodiment of the present utility model includes: a workbench 1; a robotic suction cup assembly 2, disposed at one end of the workbench 1; a panel positioning assembly 3, disposed at the top of one end of the workbench 1; a panel flipping assembly 4, disposed inside one end of the workbench 1; a panel receiving seat 5, disposed at the middle of the top of the workbench 1; and a control box 6, disposed at the middle of one side of the workbench 1. The top of the panel receiving seat 5 is provided with a plurality of grooves 501 that cooperate with the support rod 406.

[0027] It should be noted that the robotic suction cup assembly 2 consists of a bracket, a robotic arm, a suction cup execution unit, a negative pressure control unit, and a transmission component (lead screw / synchronous belt). It can use the suction cup execution unit to pick up the panel to be processed and then send it into the panel positioning assembly 3 for positioning and centering. The structure and working principle of the robotic suction cup assembly 2 are existing technologies and will not be elaborated on here.

[0028] Furthermore, the control box 6 contains a PLC control system, which is electrically connected to the robotic arm suction cup assembly 2, the panel positioning assembly 3, and the panel flipping assembly 4 in sequence. The PLC (Programmable Logic Controller) control system is a complete control unit composed of hardware modules and software programs. Its core function is to receive signals, perform logical operations, and output instructions, coordinating the three execution components to operate in an orderly manner according to the production rhythm, ensuring automated and precise operation of the entire process of gripping, positioning, and flipping. The structure and working principle of the above-mentioned PLC control system are existing technologies and will not be elaborated further here.

[0029] With the help of the above-mentioned technical solution of this utility model, the structure of this utility model is reasonable and reliable. By integrating the robotic suction cup assembly 2, the panel positioning assembly 3, the panel flipping assembly 4, and the panel receiving seat 5, a fully automated collaborative operation of grasping, positioning, flipping, and receiving is formed, which effectively improves the efficiency and accuracy of multi-panel conveying, positioning, flipping, and receiving.

[0030] In one embodiment, the panel positioning assembly 3 includes a support platform 301 disposed at one end of the worktable 1. The top of the support platform 301 has several evenly arranged panel placement slots 302. The support platform 301 has several first chambers 303 inside, and the top of each first chamber 303 has several through holes 304 penetrating the panel placement slots 302. A centering member 305 is disposed inside each first chamber 303. The centering member 305 includes a disc 3051 disposed inside the first chamber 303. The bottom of the disc 3051 has several slide rails 3052, and the top of each slide rail 3052 has a slider 3053. A drive motor 3054 is disposed at the bottom of the disc 3051 and located at the bottom of the support platform 301. The output shaft of the drive motor 3054 passes through the bottom of the first chamber 303 and is parallel to the disc 3051. 051 Fixed connection; a positioning rod 30531 is provided at one end of the top of the slider 3053, and a first fixed shaft 30532 is provided at the other end of the top of the slider 3053; several second fixed shafts 30511 are provided on the outer side of the top of the disc 3051, among which two sets of symmetrical second fixed shafts 30511 are connected to two sets of symmetrical first fixed shafts 30532 through a first connecting rod 30512, and the other two sets of symmetrical second fixed shafts 30511 are connected to the other two sets of symmetrical first fixed shafts 30532 through a second connecting rod 30513, thereby realizing the positioning and installation of the panel. Under the drive of the drive motor 3054, multiple positioning rods 30531 can be driven to center and position the panel, which can facilitate the subsequent panel flipping component 4 to grasp the panel, ensuring positioning accuracy and operational stability, and realizing automated operation to reduce manual intervention.

[0031] Furthermore, in specific applications, the lengths of the first link 30512 and the second link 30513 may be equal or unequal. When the panel is square, the lengths of the first link 30512 and the second link 30513 are equal, while when the panel is rectangular, the lengths of the first link 30512 and the second link 30513 are unequal.

[0032] The working principle of the panel positioning component 3 is as follows: The panel to be processed is transferred by the robotic suction cup component 2 to the panel placement slot 302 at the top of the support platform 301. At this time, the positioning rod 30531 is located in the through hole 304 and is not in contact with the panel. Each panel placement slot 302 corresponds to a first chamber 303 below, and the centering component 305 in the chamber is in a ready-to-start state. Then, the control box 6 commands the drive motor 3054 to start, and its output shaft drives the disc 3051 to rotate around the central axis. Several second fixed shafts 30511 on the outer side of the top of the disc 3051 rotate synchronously with the disc 3051. They form a hinged linkage with the first fixed shaft 30532 at the top of the slider 3053 through the first connecting rod 30512, the second connecting rod 30513, and the first fixed shaft 30532 at the top of the slider 3053. When the disc 3051 rotates, the first connecting rod 30512, the second connecting rod 30513, the first fixed shaft 30532 at the top of the slider 3053 form a hinged linkage. The second connecting rod 30513 is pulled or pushed, causing the slider 3053 to move linearly along the slide rail 3052 at its bottom end. Since the second fixed shaft 30511, the connecting rod and the slider 3053 are symmetrically distributed, all sliders will move synchronously along the slide rail towards or away from the center of the panel. The positioning rod 30531 at the top of the slider 3053 moves synchronously with the slider 3053 in the through hole 304. When the slider moves towards the center of the panel, the positioning rod contacts the edge of the panel synchronously from multiple symmetrical directions of the panel, such as both sides of the X-axis and Y-axis, and gradually pushes the panel to move until the center of the panel is aligned with the preset reference position of the panel placement slot 302. When the preset positioning accuracy is reached, the drive motor 3054 stops running, and the positioning rod 30531 maintains a light-touch positioning state on the panel, completing the centering.

[0033] In one embodiment, the panel flipping assembly 4 includes a support plate 401 disposed inside one end of the worktable 1. Telescopic columns 402 are provided at the four corners of the bottom end of the support plate 401, and an electric telescopic rod 403 is provided at the center of the bottom end of the support plate 401. Support seats 404 are provided at both ends of the top end of the support plate 401. A rotating shaft 405 is provided through the top of the side wall of the support seat 404. A servo motor 409 connected to the support seat 404 is provided at one end of the rotating shaft 405. The output shaft is fixedly connected to one end of the rotating shaft 405; several evenly arranged support rods 406 are provided on the outer side of the rotating shaft 405, and several suction cups 407 are provided at the top of the support rods 406; several mounting grooves 4051 that mate with the support rods 406 are provided on the outer side of the rotating shaft 405, and insertion holes 4052 are provided on both side walls of the mounting grooves 4051; a second chamber 4061 is provided inside one end of the support rods 406, and a movable plate 4062 is provided at the bottom of the second chamber 4061, with one end of the movable plate 4062 being provided with There are several springs 4063. The top of the movable plate 4062 has two insert blocks 4064 on both sides, which penetrate the sidewalls of the support rod 406 and mate with the insertion holes 4052. A connecting rod 4065 is provided at the middle of the top of the movable plate 4062, penetrating the top of the support rod 406. A sliding plate 4067 is provided at the top of the connecting rod 4065. Limiting grooves 4068 are symmetrically formed at the top of the movable plate 4062. A limiting post 4069, mates with the limiting groove 4068, is provided at one end of the insert block 4064. Two sets of limiting grooves... The distance between the slots 4068 gradually increases along the direction closer to the spring 4063, thereby realizing the flipping of the panel. The support plate 401 is precisely raised and lowered by the electric telescopic rod 403 and the telescopic column 402, and the servo motor 409 drives the rotating shaft 405 to achieve high-precision flipping of the panel. The support rod 406 on the outside of the rotating shaft stably adsorbs the panel by the suction cup 407 to avoid damage during flipping. At the same time, the quick-release structure composed of the spring 4063, the insert block 4064 and the limiting slide groove 4068 can be easily disassembled and adjusted, which also improves maintenance efficiency.

[0034] In addition, it should be noted that the top of the second chamber 4061 is provided with a sliding hole that cooperates with the connecting rod 4065, which can ensure that the connecting rod 4065 slides in a straight line.

[0035] The working principle of the panel flipping assembly 4 is as follows: Initially, the support plate 401 is in a high position under the action of the electric telescopic rod 403 and the telescopic column 402. The support rod 406 on the outside of the rotating shaft 405 and the top suction cup 407 are in a non-working state and are located inside the groove 501, waiting for the panel positioning assembly 3 to complete the panel centering. After the panel positioning assembly 3 completes the panel centering, the control box 6 drives the servo motor 409 to start. Its output shaft drives the rotating shaft 405 to rotate around the axis. The rotating shaft 405 drives the outer support rod 406 to rotate 180 degrees. Then, the suction cup 407 adsorbs the panel on the panel positioning assembly 3. After adsorption, the servo motor 409 rotates in the opposite direction and drives the rotating shaft 405 to rotate 180 degrees again. Then, the control box 6 commands the electric telescopic rod 403 to shorten, and at the same time drives the telescopic columns 402 at the four corners to extend and retract synchronously, jointly pushing the support plate 401 to descend smoothly. Then, the suction cup 407 is controlled to stop adsorbing the panel, so that the panel falls onto the panel receiving seat 5, thereby realizing the conveying of multiple panels.

[0036] When the support rod 406 needs to be disassembled and maintained, the operator pushes the sliding plate 4067 by hand, which drives the moving plate 4062 to move closer to the spring 4063 via the connecting rod 4065, compressing the spring 4063. During the movement of the moving plate, the limiting slide groove 4068 drives the insert block 4064 to retract into the second chamber 4061 via the limiting post 4069, disengaging it from the insertion hole 4052 of the rotating shaft and releasing the lock. At this time, the support rod can be directly pulled out of the mounting slot to complete the disassembly. When replacing the new support rod 406, the operation is reversed for quick installation without tools, improving maintenance and replacement efficiency.

[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0038] In practical applications, control commands are issued through the control box 6, and the robotic suction cup assembly 2 picks up the panel to be processed and transfers it to the panel positioning assembly 3 at the top of the same end of the worktable 1 (the working principle of the panel positioning assembly 3 is as described above) for centering and positioning. After positioning, the control box 6 drives the panel flipping assembly 4 (the working principle of the panel flipping assembly 4 is as described above) to pick up and flip the panel to be processed and place it stably on the panel receiving seat 5, thereby realizing the transport of the panel.

[0039] In summary, with the help of the above-mentioned technical solution of this utility model, the structure of this utility model is reasonable and reliable. By integrating the robotic suction cup assembly 2, the panel positioning assembly 3, the panel flipping assembly 4, and the panel receiving seat 5, a fully automated collaborative operation of grasping, positioning, flipping, and receiving is formed, effectively improving the efficiency and accuracy of multi-panel conveying, positioning, flipping, and receiving. By setting up the panel positioning assembly 3, the panel is positioned and installed. Driven by the drive motor 3054, multiple positioning rods 30531 are driven to center and position the panel, which facilitates the subsequent grasping of the panel by the panel flipping assembly 4. This ensures both positioning accuracy and operational stability, and achieves automated operation to reduce manual intervention. By setting up the panel flipping component 4, the panel can be flipped. The electric telescopic rod 403 and telescopic column 402 drive the support plate 401 to rise and fall precisely. With the help of the servo motor 409, the rotating shaft 405 is driven to achieve high-precision flipping of the panel. The support rod 406 on the outside of the rotating shaft is stably attached to the panel by the suction cup 407 to avoid damage during flipping. At the same time, the quick-release structure composed of spring 4063, insert block 4064 and limit slide 4068 can be easily disassembled and adjusted, which also improves maintenance efficiency.
