Description

Technical Field

[0001] This invention relates to the technical field of liquid crystal panels, and more specifically to a flip-and-receive device and a flip-and-transfer method. Background Technology

[0002] LCD panels and LCD monitors are closely related. Factors such as the production volume and quality of LCD panels directly impact the quality, price, and market trends of LCD monitors. LCD panel production is a process encompassing knowledge from multiple disciplines and fields. In recent years, the global LCD panel industry has maintained stable growth, driven by downstream demand from LCD TVs, LCD displays, and mobile phones.

[0003] As the market expands, the demand for high-quality LCD panels is also increasing. During the LCD panel manufacturing process, flipping equipment is typically used to clamp and flip the panels. Due to the large size or thickness of the LCD panels, they are prone to breakage during the flipping process. Furthermore, most existing flipping mechanisms are input-output type conveyor lines, requiring the coordination of three stations in certain environments to complete the panel flipping. Increasing the number of stations leads to a larger overall equipment size and increased production costs. Summary of the Invention

[0004] To address at least one of the problems mentioned in the background art, the present invention provides a flipping receiving device and a flipping transmission method. The dual-station operation greatly improves the flipping efficiency of the liquid crystal panel. Moreover, the flipping mechanism can be used to attract panels from both sides, further improving the efficiency of flipping the panels. A receiving mechanism is also provided on one side of the flipping mechanism. Through the setting of the receiving mechanism, the flipped panel can be smoothly transmitted, reducing the possibility of damage to the liquid crystal panel.

[0005] The specific technical solutions provided by the embodiments of the present invention are as follows:

[0006] In a first aspect, a flipping and receiving device is provided, comprising: a frame, a flipping mechanism rotatably mounted on the frame, and a receiving mechanism slidably mounted on the frame. The flipping mechanism includes a flipping frame and first adsorption components symmetrically mounted on both sides of the flipping frame. The first adsorption components are used to adsorb liquid crystal panels. The two first adsorption components are alternately flipped by rotating the flipping frame. The receiving mechanism slides to a position corresponding to the flipping mechanism to receive the liquid crystal panels adsorbed by the flipping mechanism after flipping.

[0007] Furthermore, the flipping mechanism also includes a rotating shaft passing through the flipping frame, two support columns symmetrically mounted on the frame, and a first drive motor. The rotating shaft is rotatably connected between the two support columns, and the first drive motor is used to drive the rotating shaft to rotate.

[0008] Furthermore, the receiving mechanism includes a receiving base, a turntable mounted on the receiving base via a turntable, a lifting platform mounted on the turntable, and a second adsorption component mounted on the lifting platform; the turntable is used to drive the lifting platform and the second adsorption component on the lifting platform to rotate around the turntable, the lifting platform drives the second adsorption component to rise and fall in the direction perpendicular to the receiving base, and the second adsorption component is used to receive and adsorb the liquid crystal panel.

[0009] Furthermore, the first adsorption component has the same structure as the second adsorption component. The first adsorption component includes at least two fixed profiles arranged in parallel, an adjustment groove formed on the fixed profile, a fixed plate that is detached and installed on the adjustment groove via a connector, and a plurality of suction cups installed on the fixed plate.

[0010] Furthermore, the frame is provided with a receiving compartment, and a first guide rail is provided inside the receiving compartment. The receiving base is slidably connected to the first guide rail. A second drive motor is also installed on one side of the receiving base. The second drive motor is used to drive the receiving mechanism to slide along the first guide rail.

[0011] Furthermore, a third drive motor is connected to one side of the turntable, and the drive motor is used to drive the turntable to rotate.

[0012] Furthermore, the lifting platform includes a lifting base mounted on a turntable, at least two telescopic columns symmetrically arranged on both sides of the lifting base, and a lifting panel mounted on the telescopic columns at the end away from the lifting base, wherein a second adsorption component is installed on the lifting panel.

[0013] Furthermore, a drive cylinder is also installed between the lifting base and the lifting panel.

[0014] Furthermore, the receiving base is equipped with a lead screw guide rail and a support base slidably connected to the lead screw guide rail. A turntable is installed on the support base, and a fourth drive motor is connected to one end of the lead screw guide rail.

[0015] Furthermore, the sliding direction of the lead screw guide is perpendicular to the sliding direction of the first guide.

[0016] Secondly, a flipping transmission method based on the flipping receiving device described above is provided, the steps of which include:

[0017] Based on the size of the LCD panel, the adsorption areas of the first and second adsorption components are adjusted. The transport arm places the LCD panel on the first adsorption component, while the receiving mechanism slides to the position corresponding to the flipping mechanism. The first drive motor drives the flipping frame to rotate 180°, and the receiving mechanism receives the LCD panel adsorbed by the flipping mechanism and transports it to the corresponding position. At this time, the first adsorption component on the other side of the flipping frame continues to adsorb other LCD panels to be flipped, and the receiving mechanism slides back and forth along the frame to realize the transmission of the flipped LCD panels.

[0018] The embodiments of the present invention have the following beneficial effects:

[0019] 1. By symmetrically arranging first adsorption components on both sides of the flipping frame and a receiving mechanism on one side of the flipping mechanism, the flipping frame rotates 180° to flip the LCD panel adsorbed by the first adsorption components. At this time, the receiving mechanism receives the flipped LCD panel and slides along the frame to the corresponding position to realize the transfer of the LCD panel. After the flipping frame rotates 180°, another idle first adsorption component on the flipping frame continues to pick up other LCD panels to be flipped. With the cyclic rotation of the flipping frame, the flipping and rotation of the LCD panels to be flipped are realized. The simultaneous operation of the two stations greatly improves the flipping efficiency of the LCD panel. Moreover, panels can be adsorbed on both sides of the flipping mechanism, further improving the efficiency of flipping the panel. A receiving mechanism is also provided on one side of the flipping mechanism. Through the setting of the receiving mechanism, the smooth transfer of the flipped panel is realized, reducing the possibility of damage to the LCD panel.

[0020] 2. The receiving mechanism includes a receiving base, a turntable, and a lifting platform mounted on the turntable. With the above configuration, after the receiving mechanism moves to the corresponding position with the flipping frame, the lifting platform is adjusted so that the height of the receiving mechanism is close to the flipped LCD panel on the flipping frame. Then, the first adsorption component releases the LCD panel, which is then received by the receiving mechanism. This improves the stability and safety of the LCD panel during the transfer and receiving process, and avoids damage to the LCD panel during the transfer process.

[0021] 3. A lead screw guide rail is installed on the receiving base, and the supporting base is slidably connected to the lead screw guide rail. The sliding direction of the lead screw guide rail is perpendicular to the sliding direction of the first guide rail. Through the coordination and adjustment of the two, the receiving mechanism can transfer the received LCD panel to the corresponding position. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] Currently, LCD panels and LCD monitors are closely related. The output and quality of LCD panels significantly impact the quality, price, and market trends of LCD monitors. LCD panel production is a process encompassing multiple disciplines and fields of knowledge. In recent years, the global LCD panel industry has maintained stable growth, driven by downstream demand from LCD TVs, LCD displays, and mobile phones. During LCD panel production, flipping equipment is typically used to clamp and flip the panels. However, due to the large size or thickness of LCD panels, breakage during flipping is a potential issue. Furthermore, most existing flipping mechanisms are input-output type conveyor lines, requiring three stations in certain environments to complete the flipping process. Increasing the number of stations leads to a larger overall equipment size and increased production costs. Based on these issues, this application proposes a flipping receiving device and a flipping transmission method. This dual-station operation significantly improves the flipping efficiency of LCD panels. Furthermore, panels can be attracted from both sides of the flipping mechanism, further enhancing efficiency. A receiving mechanism is also provided on one side of the flipping mechanism to ensure smooth transmission of the flipped panel, reducing the possibility of damage.

[0030] Example 1

[0031] A flipping receiving device is provided, such as Figure 1 and 2 As shown, the device includes a frame 1, a flipping mechanism 2 rotatably mounted on the upper part of the frame 1, and a receiving mechanism 3 slidably mounted on the frame 1. To reduce the weight of the device, the frame 1 is designed as a hollow cuboid, and the overall height of the receiving mechanism 3 is lower than that of the flipping mechanism 2. Specifically, the flipping mechanism 2 includes a flipping frame 201 and first adsorption components 202 symmetrically mounted on both sides of the flipping frame 201. The first adsorption components 202 are used to adsorb the liquid crystal panel to be flipped. The two first adsorption components 202 are alternately flipped by rotating the flipping frame 201. A transport and transfer arm places the liquid crystal panel to be flipped on the flipping structure. The flipping mechanism 2 is used to grasp the liquid crystal panel and flip it 180°. The receiving mechanism 3 slides to the position corresponding to the flipping mechanism 2 to receive the liquid crystal panel adsorbed by the flipping mechanism 2 after flipping.

[0032] Specifically, the flipping mechanism 2 also includes a rotating shaft 4, two support columns 5 symmetrically mounted on the frame 1, and a first drive motor 6. The rotating shaft 4 is rotatably inserted into the flipping frame 201 through bearings to drive the flipping frame 201 to rotate. The support columns 5 are vertically mounted on the frame 1 through connectors. One end of the rotating shaft 4 passes through the support column 5 and is connected to the output shaft of the first drive motor 6, so that the flipping frame 201 is driven to rotate by the first drive motor 6.

[0033] To ensure the smooth transport of the flipped LCD panel to its corresponding position, a receiving mechanism 3 is provided at the lower part of the flipping mechanism 2. The receiving mechanism 3 includes a receiving base 301, a turntable 302, a lifting platform 303 mounted on the turntable 302, and a second adsorption component 304 mounted on the lifting platform 303. A support base 7 is mounted on the receiving base 301, and a cylindrical turntable 8 is mounted on the support base 7. The turntable 302 is rotatably connected to the support base 7 via the turntable 8. The turntable 302 rotates under the drive of the turntable 8, which in turn drives the lifting platform 303 on the turntable 302 and the second adsorption component 304 on the lifting platform 303 to rotate around the turntable 8. This allows for adjustment of the orientation of the LCD panel on the receiving mechanism 3, making the flipped LCD panel suitable for the next process operation. With the lifting platform 303 in place, after the receiving mechanism 3 slides to the corresponding position with the flipping mechanism 22, the lifting platform 303 drives the second adsorption component 304 to vertically lift and lower along the direction perpendicular to the receiving base 301, so that the second adsorption component 304 is close to the liquid crystal panel on the first adsorption component 202, so that the liquid crystal panel can be stably transported. A third drive motor 9 is also installed on one side of the base plate, which is used to drive the turntable 8 to rotate the turntable 302.

[0034] like Figure 4 As shown, specifically, the lifting platform 303 includes a lifting base 3031 mounted on the upper part of the turntable 302, a telescopic column 3032, and a lifting panel 3033 mounted on the end of the telescopic column 3032 away from the lifting base 3031. The second adsorption assembly 304 is mounted on the lifting panel 3033. The lifting base 3031 is rectangular, and four telescopic columns 3032 are symmetrically arranged at the four corners of the lifting base 3031. Each telescopic column 3032 is perpendicular to the lifting base 3031. A drive cylinder 10 is also provided on the lifting base 3031. Two drive cylinders 10 are symmetrically arranged about the center of the lifting base 3031, and one end of the piston rod of the drive cylinder 10 is connected to the lifting panel 3033. The drive cylinders 10 are used to drive the lifting panel 3033 to adjust its height along the telescopic column 3032.

[0035] To facilitate the convenient transfer of the received LCD panel to the corresponding position by the receiving mechanism 3, a receiving compartment 11 is provided in the middle of the frame 1. A first guide rail 12 is installed on the inner wall of the receiving compartment 11, with two first guide rails 12 symmetrically installed on the inner walls of both sides of the receiving compartment 11. Sliding seats are installed on both sides of the receiving base 301, and two sliding seats are slidably connected to the two first guide rails 12 respectively. An optical axis 13 connects the two sliding seats. A second drive motor 14 is also installed on one side of the receiving base 301. The second drive motor 14 drives the sliding seats to slide along the first guide rails 12, thereby enabling the receiving mechanism 3 to slide along the first guide rails 12.

[0036] Because market demands for LCD panel sizes vary, the sizes of LCD panels produced in different batches also differ. To enable this device to handle the flipping of LCD panels of different sizes, the adsorption area of ​​the first adsorption component 202 is adjustable. Specifically, as... Figure 2 As shown, the first adsorption component 202 includes two parallel fixed profiles 2021, each in a cuboid shape. Several shorter fixed profiles 2021 are laterally connected between the two parallel fixed profiles 2021, forming a cuboid support frame. An adjustment groove 15 is provided on each fixed profile 2021, extending along its length. A fixed plate 16 is detachably connected to the adjustment groove 15 via a connector. Both ends of the fixed plate 16 are mounted on the two fixed profiles 2021, which are arranged in parallel. Several suction cups 17 are mounted on the fixed plate 16, evenly distributed along its length. The suction cups 17 are connected to an external vacuum system via pipes. Operators can adjust the number of fixed plates 16 and the distance between them according to the size of the LCD panel to be flipped, thereby adjusting the adsorption area of ​​the first adsorption component 202. Both the first adsorption component 202 and the second adsorption component 304 are connected to an external vacuum system via pipes.

[0037] Furthermore, the structure of the second adsorption component 304 in the receiving mechanism 3 is the same as that of the first adsorption component 202, thereby improving the stability of the liquid crystal panel during the entire flip-transfer process.

[0038] After the receiving mechanism 3 transfers the LCD panel from the bottom of the flipping mechanism 2, it needs to be transported to its corresponding position. Therefore, the receiving base 301 is also equipped with a lead screw guide rail 18 and a support base 7 slidably connected to the lead screw guide rail 18. A turntable 8 is installed on the support base 7. The length direction of the lead screw guide rail 18 is perpendicular to the direction of the first guide rail 12. Since the components on the receiving base 301 are heavy and need to support the transferred LCD panel, it is necessary to ensure that the receiving base 301 is smoothly adjusted along the lead screw guide rail 18 to prevent it from tilting. Therefore, auxiliary guide rails 19 are symmetrically installed on both sides of the lead screw guide rail 18. Auxiliary sliding plates 20 are symmetrically installed on both sides of the receiving base 301. The auxiliary sliding plates 20 are provided with guide grooves. Through the setting of the guide grooves, the auxiliary sliding plates 20 and the auxiliary guide rails 19 slide together, thereby ensuring that the receiving base 301 can slide smoothly along the lead screw guide rail 18. A fourth drive motor is also connected to one end of the lead screw guide rail 18. The fourth drive motor is used to drive the receiving base 301 to be stably adjusted along the direction of the lead screw guide rail 18.

[0039] To facilitate maintenance of this device, several inspection doors 21 are provided on both sides of the frame 1. Eight support legs and eight casters are symmetrically installed at the bottom of the frame 1, evenly distributed on both sides. The support legs are adjustable in height. When the device needs to be fixed in a certain position, the length of the support legs to the ground is adjusted to be greater than the length of the casters to the ground; when the device needs to be moved, the length of the support legs to the ground is adjusted to be less than the length of the casters to the ground. This reduces the friction between the device and the ground, facilitating its transport.

[0040] This device is electrically connected to the controller via a cable. The controller is used to control the flipping mechanism 2 and the coordinated operation of the first drive motor 6, the second drive motor 14, the third drive motor 9, and the fourth drive motor.

[0041] like Figure 1 As shown, in order to achieve the function of pulling and protecting cables, pipes, etc. on the receiving mechanism 3, a drag chain is connected to one side of the receiving mechanism 3. In this embodiment, the connecting parts all refer to bolts.

[0042] Specific implementation process: Based on the required size of the LCD panel to be flipped, the operator adjusts the number and density of the fixing plates 16 on the fixing profile 2021 to adjust the adsorption area of ​​the first adsorption component 202 and the second adsorption component 304. Then, the transport robot places the LCD panel to be flipped onto the first adsorption component 202. Simultaneously, the second drive motor 14 drives the receiving mechanism 3 to move along the first guide rail 12 to below the flipping mechanism 2. Then, the first drive motor 6 drives the flipping frame 201 to rotate 180° around the rotating shaft 4, completing the flipping of the LCD panel. At this time, the lifting panel 3033 rises to the desired height under the action of the drive cylinder 10. The first adsorption component 202 releases the LCD panel from the first adsorption component 202, and then the second adsorption component 304 receives the adsorbed LCD panel. The second drive motor 14 then drives the receiving mechanism 3 to transport the LCD panel to the corresponding position along the first guide rail 12. Meanwhile, another first adsorption component 202 on the upper part of the flipping mechanism 2 continues to adsorb other LCD panels to be flipped. After the receiving mechanism 3 moves away from the flipping mechanism 2, the first drive motor 6 drives the flipping frame 201 to flip, completing the flipping of the second LCD panel. At this point, the receiving mechanism 3 moves closer to the flipping mechanism 2 again, completing the receiving of the second flipped LCD panel. This cycle repeats, achieving the flipping and transmission of the LCD panels. The simultaneous operation of the dual stations greatly improves the flipping efficiency of the LCD panels. Furthermore, panels can be adsorbed on both sides of the flipping mechanism 2, further enhancing the flipping efficiency. A receiving mechanism 3 is also provided on one side of the flipping mechanism 2. This receiving mechanism 3 ensures smooth transmission of the flipped panels, reducing the possibility of damage to the LCD panels.

[0043] Example 2

[0044] Corresponding to the above embodiments, this application provides a flipping transmission method based on the flipping receiving device described above, specifically including the following steps:

[0045] Depending on the size of the LCD panel to be flipped, the operator adjusts the number and density of the fixing plates 16 on the fixing profile 2021 to adjust the adsorption area of ​​the first adsorption component 202 and the second adsorption component 304. Then, the transport robot places the LCD panel to be flipped on the first adsorption component 202. At the same time, the second drive motor 14 drives the receiving mechanism 3 to move along the first guide rail 12 to below the flipping mechanism 22. Then, the first drive motor 6 drives the flipping frame 201 to rotate 180° around the rotating shaft 4, completing the flipping of the LCD panel. At this time, the lifting panel 3033 rises to a position close to the first adsorption component 202 under the action of the drive cylinder 10. The height of the liquid crystal panel on the first adsorption component 202 is determined by the following steps: the first adsorption component 202 releases the liquid crystal panel, and then the second adsorption component 304 receives the adsorbed liquid crystal panel. Then, the second drive motor 14 drives the receiving mechanism 3 to transport the liquid crystal panel to the corresponding position along the first guide rail 12. At this time, another first adsorption component 202 on the upper part of the flipping mechanism 2 continues to adsorb other liquid crystal panels to be flipped. After the receiving mechanism 3 moves away from the flipping mechanism 2, the first drive motor 6 drives the flipping frame 201 to flip, completing the flipping of the second liquid crystal panel. Then, the receiving mechanism 3 moves closer to the flipping mechanism 2 to receive the second flipped liquid crystal panel. This cycle repeats, realizing the flipping and transmission of the liquid crystal panel. The simultaneous operation of the two stations greatly improves the flipping efficiency of the liquid crystal panel. Furthermore, panels can be adsorbed on both sides of the flipping mechanism 2, further improving the efficiency of panel flipping. A receiving mechanism 3 is also provided on one side of the flipping mechanism 2. Through the setting of the receiving mechanism 3, the smooth transmission of the flipped panel is achieved, reducing the possibility of damage to the liquid crystal panel.
