Description

Technical Field

[0001] This invention relates to the field of flexible panel processing equipment, and more specifically to a flexible panel adsorption platform replacement device. Background Technology

[0002] OLED display technology features self-illumination, wide viewing angle, high contrast, low power consumption, and fast response speed, and is now widely used in the production of various display devices, from smartwatches to digital TVs. Currently, the manufacturing process for flexible OLED panels often involves first fabricating multiple flexible OLED display panels on a large glass substrate, called the master substrate. After the master substrate is fabricated, it is then cut into individual OLED display panels as required by the customer. A common approach is to first remove the glass substrate from the master substrate and attach a large PET protective film before cutting it into individual OLED display panels.

[0003] When the motherboard on the cutting table is cut into dozens or even hundreds of OLED panels, a single-panel adsorption platform is needed to pick up all the OLED panels and the waste material between them and remove the waste. Therefore, a different adsorption platform needs to be designed for each size of OLED panel, with the vacuum adsorption holes corresponding to the positions of the OLED panel and the waste material. Consequently, the single-panel adsorption platform needs to be replaced each time the machine cuts OLED panels of different sizes. If the single-panel adsorption platform is replaced manually, it will significantly reduce production efficiency, is very inconvenient, and is prone to damage from impacts. Therefore, a flexible OLED panel adsorption platform that can be replaced with a single click needs to be designed. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a flexible panel adsorption platform replacement device to improve the technical problem that the existing flexible panel adsorption platform requires manual replacement and has low production efficiency.

[0005] To achieve the above and other related objectives, the present invention provides a flexible panel adsorption platform replacement device, comprising: a swing support device disposed on both sides of an adsorption platform mounting bracket, wherein the swing support device supports the adsorption platform when it detaches from the mounting bracket; a traction component that drives the adsorption platform to move; the traction component comprising a first transmission module and an insert cylinder, wherein the insert cylinder is inserted into a groove of the adsorption platform, and the first transmission module drives the insert cylinder and the adsorption platform to move together; and a first guide component that provides guidance for the adsorption platform when it moves into or out of the mounting bracket.

[0006] In an exemplary embodiment of this application, the swing support device includes a swing assembly and a support assembly; the swing assembly includes a swing cylinder, a first base plate, and a first fixed base. One end of the swing cylinder is rotatably mounted on a cylinder seat, and the other end of the swing cylinder is rotatably connected to the first base plate. The first base plate is rotatably mounted on the first fixed base. The extension and retraction of the swing cylinder causes the first base plate to rotate around the first fixed base. The support assembly is mounted on the first base plate. The support assembly includes a support plate and a first lifting cylinder. When the swing cylinder retracts, the swing support device is located above the adsorption platform. When the swing cylinder extends, the support plate rotates to the bottom of the adsorption platform. The extension and retraction of the first lifting cylinder causes the support plate to move linearly.

[0007] In an exemplary embodiment of this application, the support component includes a linear guide rail, and the first lifting cylinder drives the support plate to move linearly along the linear guide rail.

[0008] In an exemplary embodiment of this application, the support component includes a buffer and a limiting block. The buffer is fixed relative to the support plate. When the buffer contacts the limiting block, the first lifting cylinder reaches a set stroke. In an exemplary embodiment of this application, the first guide component includes a first mounting member, a first guide cylinder, and a first guide wheel. The first guide cylinder is mounted on the first mounting member and drives the first guide wheel to move closer to or further away from the adsorption platform.

[0009] In an exemplary embodiment of this application, a frame and a second guide assembly are included; the traction assembly is mounted on the frame; the second guide assembly is mounted on the frame, and the traction assembly drives the adsorption platform to move linearly along the second guide assembly.

[0010] In an exemplary embodiment of this application, the adsorption platform is provided with a plurality of grooves, which are arranged along the moving direction of the adsorption platform.

[0011] In an exemplary embodiment of this application, the distance between adjacent grooves is not greater than the stroke of the first transmission module.

[0012] In an exemplary embodiment of this application, a pressure plate assembly is included, the pressure plate assembly including a pressure plate cylinder and a pressing block, the pressure plate cylinder driving the pressing block to move linearly to restrict or release the movement of the adsorption platform.

[0013] In an exemplary embodiment of this application, a plurality of first rolling elements are provided on the frame, and the plurality of first rolling elements are mounted on the frame. When the traction component drives the adsorption platform to move, the first rolling elements contact the bottom surface of the adsorption platform.

[0014] The beneficial effects of this invention, in combination with existing technologies, are as follows: Existing adsorption platforms are typically replaced manually, which is time-consuming and labor-intensive. This application addresses this issue by incorporating a swing support device. This device provides support for the adsorption platform during detachment or assembly onto the mounting bracket, facilitating both the removal and installation of the platform and the docking of the traction component. The traction component moves the adsorption platform to the designated area, where a suitable replacement platform is then positioned at the swing support device. A first guide component guides the platform, ensuring accurate positioning during insertion and removal and guaranteeing stable platform replacement. Attached Figure Description

[0021] Existing flexible panel adsorption platforms require manual replacement, which is time-consuming and labor-intensive. The adsorption platforms are also easily damaged, resulting in low production efficiency. This application seeks to protect a flexible panel adsorption platform replacement device that can realize the automatic replacement of flexible panels and improve production efficiency.

[0022] The flexible panel adsorption platform replacement device includes a transmission device 1, a swing support device 2, and a first guide component 3. When replacing the adsorption platform, the adsorption platform is separated from the mounting bracket under the guidance of the first guide component 3 and the support of the swing support device 2. Then, the transmission device 1 moves the replaced adsorption platform to the MGV trolley, and the new adsorption platform is taken off the MGV trolley and transported to the swing support device 2. Under the support of the swing support device 2 and the guidance of the first guide component 3, the new adsorption platform is installed on the mounting bracket, completing the replacement of the adsorption platform.

[0023] Please see Figure 1 , Figure 1 This is a schematic diagram of an exemplary transmission device structure according to this application. The transmission device 1 includes frames disposed on the left and right sides, and a traction assembly 11 is provided on at least one side of the frame. In one embodiment, the traction assembly includes a first transmission module 111, a traction seat plate 112, and a block cylinder 11. In one embodiment, the first transmission module 111 can be a motor driving a lead screw to rotate and a slider to reciprocate linearly along the lead screw, or it can be a cylinder driving a slider, or it can be a belt drive, etc., selected according to actual needs. In one embodiment of this application, the first transmission module 111 is preferably a lead screw drive.

[0024] Please see Figure 2 , Figure 2 This is a schematic diagram of an exemplary traction component structure according to this application. In one embodiment, the traction seat plate 112 is mounted on the slider of the first transmission module 111, and the insert cylinder 113 is mounted on the traction seat plate 112. The adsorption platform is provided with a groove 4, and the insert cylinder 113 is inserted into the groove 4 of the adsorption platform. Then, the first transmission module 111 drives the insert cylinder 113 and the adsorption platform to move back and forth.

[0025] The adsorption platform is large in size and has a long transmission distance, while the stroke of the first transmission module 111 is limited. Choosing a larger stroke would significantly increase costs. Please refer to [link / reference needed]. Figure 11 , Figure 11This is a schematic diagram of an exemplary adsorption platform according to this application. In one embodiment, the adsorption platform is provided with a plurality of grooves 4, which are arranged along the moving direction of the adsorption platform. The span between adjacent grooves 4 is no greater than the stroke of the first transmission module 111. During the transportation of the adsorption platform, the insert cylinder 113 is inserted into one of the grooves 4, and the first transmission module 111 drives the adsorption platform to move a certain distance. Then, the insert cylinder 113 retracts, and the first transmission module 111 drives the insert cylinder 113 to reset. Then, the insert cylinder 113 extends back into the groove 4 of the adsorption platform, and the cycle repeats until the adsorption platform is moved to the designated position. By setting a plurality of grooves 4 on the adsorption platform, the first transmission module 111 with a shorter stroke can achieve transportation over a longer distance, saving costs and improving transportation accuracy.

[0026] Please continue reading. Figure 2 In one embodiment, the traction assembly 11 further includes a second guide wheel 114, which is installed on both sides of the insert cylinder 113. When transporting the adsorption platform, the second guide wheel 114 supports the bottom of the adsorption platform and provides support for the adsorption platform.

[0027] Please see Figure 3 In one embodiment, the transmission device 1 includes a second guide assembly 12, with the second guide assembly 12 mounted on both sides of the frame. The second guide assembly 12 includes third guide wheels 121 horizontally mounted on the left and right sides, ensuring that the adsorption platform does not tilt in the horizontal plane during movement. In another embodiment, the second guide assembly 12 includes a fourth guide wheel 122 vertically mounted on the frame. The fourth guide wheel 122 contacts the top surface of the adsorption platform. During the movement of the adsorption platform, the fourth guide wheel 122 presses against the adsorption platform to ensure that the adsorption platform does not tilt during movement and to prevent the adsorption platform from tilting.

[0028] In one embodiment, the transmission device 1 includes a pressure plate assembly 13, which includes a pressure plate cylinder 131 and a clamping block 132. When the insertion block cylinder 113 leaves the groove 4 and resets, to prevent the adsorption platform from moving along the second guide assembly 12 and causing problems such as inaccurate positioning, the pressure plate cylinder 131 drives the clamping block 132 to clamp the adsorption platform, thereby preventing the adsorption platform from moving. When the insertion block cylinder 113 is inserted into the groove 4, the pressure plate cylinder 131 drives the clamping block 132 away from the adsorption platform, and the adsorption platform continues to move with the insertion block cylinder 113. In one embodiment, the clamping block 132 is a polyurethane clamping block to avoid damage to the adsorption platform during the clamping process.

[0029] In one embodiment, the transmission device 1 includes a first rolling assembly 14, which includes a first rolling body 141 disposed on the frame. During the movement of the adsorption platform, the bottom surface of the adsorption platform comes into contact with the first rolling body 141, changing the original sliding friction into rolling friction, reducing friction and reducing wear on the bottom surface of the adsorption platform.

[0030] In one embodiment, a first sensor 15 is installed inside the frame. The first sensor 15 can detect whether the emitted light is blocked, thereby determining the position of the adsorption platform and controlling the movement of the traction component 11 according to the position of the adsorption platform.

[0031] Please see Figure 4 , Figure 4 This is a schematic diagram of an exemplary swing support device according to this application. The swing support device 2 is disposed on both sides of the adsorption platform mounting bracket. The two sides have the same structure, both including a swing component 21 and a support component 22.

[0032] Please see Figure 5 , Figure 5 This is a schematic diagram of an exemplary swing assembly 21 of this application. In one embodiment, the swing assembly 21 includes a swing cylinder 211, a first cylinder seat 212, a first connecting plate 213, a first fixed seat 214, a pin 215, and a first base plate 216. One end of the swing cylinder 211 is rotatably mounted on the first cylinder seat 212, and the other end of the swing cylinder 211 is rotatably mounted on the first base plate 216 via the pin 215. The first base plate 216 is rotatably connected to the first fixed seat 214 via the first connecting plate 213. The swing cylinder 211 extends and retracts, causing the first base plate 216 to rotate around the first fixed seat 214. When the swing cylinder 211 retracts, the swing support device 2 is located above the adsorption platform. When the swing cylinder 211 extends, the first base plate 216 rotates around the first fixed seat 214, causing part of the swing support device 2 to rotate to the bottom surface of the adsorption platform to support the adsorption platform.

[0033] Please see Figures 6-7 , Figure 6 , Figure 7 This is a schematic diagram of an exemplary support component 22 of this application. The support component 22 is mounted on a first base plate 216 and includes a support plate 221 and a first lifting cylinder 222. In one embodiment, the support plate 221 is L-shaped, and two L-shaped support plates 221 are symmetrically arranged on both sides of the mounting bracket. When the swing cylinder 211 extends to a set stroke, one side of the L-shaped support plate 221 is in a horizontal state, and the other side is in a vertical state to support the bottom and sides of the adsorption platform. The first lifting cylinder 222 is mounted on the first base plate 216, and the support plate 221 is mounted on the extension end of the first lifting cylinder 222. The first lifting cylinder 222 drives the support plate 221 to move up and down, thereby moving the adsorption platform away from or closer to the mounting bracket.

[0034] In one embodiment, the support component 22 includes a second rolling guide component 223, which includes a plurality of second rolling elements 2231. In one embodiment, the second rolling elements 2231 are disposed on the bottom surface and side surface of the L-shaped support plate 221 to reduce the frictional force experienced by the adsorption platform when it moves on the support plate 221 and reduce the wear of the adsorption platform.

[0035] In one embodiment, the support component 22 includes a linear guide rail 224, and the support plate 221 moves linearly along the linear guide rail 224. The linear guide rail 224 provides guiding support to avoid the first lifting cylinder 222 being subjected to shearing force and to extend its service life.

[0036] In one embodiment, the support component 22 includes a buffer 225 and a limiting block 226. The buffer 225 is fixed relative to the support plate 221. When the buffer 225 contacts the limiting block 226, the first lifting cylinder 222 stops operating and waits for the next instruction. The buffer 225 provides buffering and limiting functions to prevent the support plate 221 from moving beyond its preset stroke and causing damage.

[0037] In one embodiment, a second sensor 227 is provided on the support plate 221, which is used to detect whether there is an adsorption platform at the current position.

[0038] Please see Figure 8 , Figure 8 This is a schematic diagram of the swing cylinder retracting in this application. When the swing cylinder 211 is in the retracted state, the swing support device 2 is located above the adsorption platform mounting bracket. When the swing cylinder 211 extends to its maximum stroke, the swing support device 2... Figure 9 As shown, the first base plate 216 swings around the first fixed base 214 to both sides of the adsorption platform, and the second rolling element 2231 on the support plate 221 just contacts the bottom and both sides of the adsorption platform. When the second sensor 227 senses the adsorption platform, the first lifting cylinder 222 is activated, causing the support plate 221 to rise or fall, thereby docking with the transmission device 1.

[0039] Please see Figure 10 , Figure 10 This application provides an exemplary schematic diagram of a first guide component. When the adsorption platform moves into or out of the mounting bracket, the first guide component 3 provides guidance for the adsorption platform. The first guide component 3 includes a first guide cylinder 31 and a first guide wheel 32. When the adsorption platform moves into or out of the mounting bracket, the first guide cylinder 31 extends and the first guide wheel 32 abuts against the adsorption platform to achieve the guiding function and ensure accurate positioning when the adsorption platform moves into or out of the mounting bracket.

[0040] When the adsorption platform needs to be replaced, the mounting bracket with the adsorption platform is moved to the front end of the transmission device 1 via the machine's module movement. The telescopic rod of the swing cylinder 211 of the swing support device 2 extends, causing the first seat plate 216 to rotate around the first fixed seat 214, thereby causing the support plate 221 to rotate to the bottom and sides of the adsorption platform to receive it. Subsequently, the machine's clamping module releases, and the adsorption platform is supported by the second rolling element 2231 on the support plate 221. After the second sensor 227 senses the adsorption platform, the piston rod of the first lifting cylinder 222 extends, causing the support plate 221 to descend, thereby driving the adsorption platform to descend synchronously until the buffer 225 contacts the limit block 226, and the adsorption platform descends to the designated position.

[0041] The insert cylinder 113 is inserted into the groove 4 of the adsorption platform. Then, the slider of the first transmission module 111 drives the insert cylinder 113 and the adsorption platform to move out of the support plate 221. At this time, the piston rod of the first guide cylinder 31 at the front end of the bracket extends and the first guide wheel 32 abuts against the adsorption platform to achieve the guiding function. The adsorption platform has multiple grooves. When the insert cylinder 113 is inserted into the groove 4, the first transmission module 111 drives the adsorption platform to move a certain distance. Then the insert cylinder 113 retracts, the pressure plate assembly 13 presses down on the adsorption platform, and the first transmission module 111 returns to its original position. At this time, the insert cylinder 113 extends again and inserts into the adjacent groove 4. The pressure plate assembly 13 releases, and this cycle repeats until the adsorption platform is moved to the MGV trolley for storage. The adsorption platform to be replaced is then obtained from the MGV trolley. Using a step-by-step traction method, the adsorption platform is pulled onto the support plate 221. Then, the first lifting cylinder 222 retracts, the support plate 221 rises, and the clamping module is activated, fixing the adsorption platform on the mounting bracket. The swing cylinder 211 of the swing support device 2 retracts, driving the first seat plate 216 to rotate around the first fixed seat 214, thereby causing the support plate 221 to rotate to the upper end of the mounting bracket and return to its original position.

[0042] This invention relates to a flexible panel adsorption platform replacement device, which offers the advantages of automatic replacement of the flexible panel adsorption platform, high production efficiency, and a high degree of automation. Therefore, this invention effectively overcomes some practical problems in the prior art, thus possessing high utilization value and practical significance. The above embodiments are merely illustrative of the principles and effects of this invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this invention.
