Description

Technical Field

[0001] This utility model relates to the field of display panel manufacturing technology, specifically to a display panel processing and leveling mechanism. Background Technology

[0002] A display screen is a tool that transmits electronic documents to a screen and then reflects them to the human eye. The display panel is an important component of a monitor, responsible for controlling the liquid crystal display, including image processing and display chip functions. It is an internal component of the screen and directly affects the display effect and user experience. Display panels are generally of two types: rigid and flexible. For flexible display panels, a flattening process is performed during production to ensure the flatness of the display panel and avoid problems such as wrinkles and bulges.

[0003] For example, a leveling mechanism for processing a display screen backplate, with application number CN202121984996.6 and authorization announcement date of 20220111, relates to the field of backplate technology. It includes an operating table with a leveling mechanism on one side and an adjustment mechanism on the other. In this invention, the display screen backplate is placed on one side of two L-shaped blocking plates facing each other. The display screen backplate presses against the pressing plate, and the two resetting telescopic tubes are in a stretched state. At this time, the external power supply of the motor is turned on. When the motor drives the movable block to rotate, the movable rod slides inside the loop-shaped sleeve, thereby driving the loop-shaped sleeve to move back and forth, and driving the sliding plate to slide inside the strip-shaped blocking plate and one of the L-shaped blocking plates, thus pressing the display screen backplate. Through the inclined setting of the two guide blocks, the display screen backplate slides inside the strip-shaped blocking plate and the other L-shaped blocking plate, achieving continuous feeding and leveling, and improving work efficiency.

[0004] To flatten flexible display panels, a flattening mechanism is used. However, traditional flattening mechanisms require manual operation, which involves manually aligning the display panel to be flattened. This process is time-consuming and significantly reduces the effectiveness of the flattening mechanism. Therefore, it is urgent to design a new flattening mechanism for display panel processing to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a display panel processing and leveling mechanism to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A display panel processing and leveling mechanism includes a bottom mold assembly. An upper mold assembly is bolted to both outer walls of the top of the bottom mold assembly. The bottom mold assembly includes a base. Each outer wall of the top of the base has a mounting groove, and a lead screw is mounted inside the mounting groove via bearings. A limiting component is slidably connected inside the mounting groove, and the limiting component is threadedly connected to the lead screw. A drive motor is bolted to all four outer walls of the base, and the output end of the drive motor is fixedly connected to one end of the lead screw. The limiting component includes a nut plate, which is threadedly connected to the lead screw. A support plate is integrally formed on one outer wall of the nut plate, and an installation groove is formed on one outer wall of the nut plate. A pressing assembly is located inside the installation groove. A pump body is bolted to one outer wall of the nut plate. The pressing assembly includes two telescopic cylinders. A pressure block is bolted to the output end of each of the two telescopic cylinders, and a rubber block is adhered to one outer wall of the bottom of the pressure block. The telescopic cylinders are interconnected with the pump body via pipes.

[0008] Furthermore, a groove is provided on one side of the outer wall of the top of the base, and a top plate is slidably inserted into the groove.

[0009] Furthermore, a placement area is provided on one side of the outer wall of the base, and a lifting cylinder is installed at the center of one side of the inner wall of the placement area by bolts. The output end of the lifting cylinder is fixedly connected to the outer wall of one side of the top plate by bolts.

[0010] Furthermore, the upper mold assembly includes two support rods, one end of which is bolted to the outer walls on both sides of the top of the base.

[0011] Furthermore, a support plate is bolted to one end of each of the two support rods, and a downward pressure cylinder is bolted to the center of the outer wall of one side of the support plate.

[0012] Furthermore, a pressing mold is bolted to the output end of the pressing cylinder, the pressing mold including a pressure plate, and the output end of the pressing cylinder is fixedly connected to the pressure plate by bolts.

[0013] Furthermore, the pressure plate has sliding grooves on all four outer walls, and sliding plates are slidably inserted into the sliding grooves.

[0014] Furthermore, a telescopic tube is installed on one side of the inner wall of the chute by bolts, and the other end of the telescopic tube is fixedly connected to the sliding plate by bolts. An air pump is installed inside the chute, and the air pump is connected to the four telescopic tubes through pipes.

[0015] In the above technical solution, the display panel processing and leveling mechanism provided by this utility model has the following beneficial effects:

[0016] (1) By setting the lead screw, drive motor and limiting parts, the flexible display panel to be leveled is placed on the base. Then, the four drive motors can be started. The drive motors will rotate with the corresponding lead screws. The rotating lead screws will slide with the limiting parts inside the placement groove. The four limiting parts slide together to limit the flexible display panel, so that the flexible display panel is centered on the base. This achieves the purpose of quickly straightening the flexible display panel, which facilitates the subsequent leveling process and greatly improves the continuous leveling speed of the leveling mechanism.

[0017] (2) After the four limiting components are aligned with the flexible display panel, the edge of the panel will be stuck inside the mounting groove. Then, the pump body is started, and air will enter the two telescopic cylinders. Then, the pressure block will slide inside the mounting groove with the rubber block to restrict the edge of the flexible display panel, so that the display panel is firmly fixed by the limiting components. Then, the four drive motors are started, and the limiting components will pull the four sides of the panel in four directions, so that the panel unfolds and the wrinkled parts of the panel are pulled open. With the flattening of the upper mold assembly, the flattening effect can be improved.

[0018] (3) After the leveling is completed by setting up the lifting cylinder and the top plate, the lifting cylinder can be started. When the lifting cylinder is started, the top plate will rise inside the groove, so that the top plate will lift the leveled flexible display panel on the base, so that the workers can quickly take the leveled flexible display panel.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-7 As shown in the figure, the display panel processing and leveling mechanism provided by this utility model includes a bottom mold assembly 1. An upper mold assembly 2 is bolted to both outer walls of the top of the bottom mold assembly 1. The bottom mold assembly 1 includes a base 3. A mounting groove 4 is formed on both outer walls of the top of the base 3. A lead screw 5 is mounted inside the mounting groove 4 via bearings. A limiting member 7 is slidably connected inside the mounting groove 4, and the limiting member 7 is threadedly connected to the lead screw 5. A drive motor 6 is bolted to all four outer walls of the base 3, and the output end of the drive motor 6 is fixedly connected to one end of the lead screw 5. Next, the limiting component 7 includes a nut plate 12, which is threadedly connected to the lead screw 5. A support plate 13 is integrally formed on one side of the outer wall of the nut plate 12. An installation groove 14 is opened on one side of the outer wall of the nut plate 12, and a pressing component 16 is provided inside the installation groove 14. A pump body 15 is installed on one side of the outer wall of the nut plate 12 by bolts. The pressing component 16 includes two telescopic cylinders 17. A pressure block 18 is installed on the output end of the two telescopic cylinders 17 by bolts, and a rubber block 19 is adhered to one side of the bottom outer wall of the pressure block 18. The telescopic cylinders 17 are interconnected with the pump body 15 through pipes.

[0031] Specifically, in this embodiment, a bottom mold assembly 1 is included. An upper mold assembly 2 is bolted to the outer walls of both sides of the top of the bottom mold assembly 1. The bottom mold assembly 1 includes a base 3. A mounting groove 4 is formed on the outer walls of both sides of the top of the base 3. A lead screw 5 is mounted inside the mounting groove 4 via a bearing. A limiting component 7 is slidably connected inside the mounting groove 4, and the limiting component 7 is threadedly connected to the lead screw 5. A drive motor 6 is bolted to the outer walls of all four sides of the base 3. The preferred model of the drive motor 6 is 42BYGHW615-04. For leveling, the flexible display panel to be leveled can be placed on the base. Following step 3, the four drive motors 6 are then started. The drive motors 6 will then rotate the corresponding lead screws 5. The rotating lead screws 5 will cause the limiting members 7 to slide inside the mounting groove 4. The simultaneous sliding of the four limiting members 7 can limit the flexible display panel, ensuring that the flexible display panel is centered on the base 3, achieving the purpose of quickly aligning the flexible display panel. The output end of the drive motor 6 is fixedly connected to one end of the lead screw 5. The limiting member 7 includes a nut plate 12, which is threadedly connected to the lead screw 5. One side of the nut plate 12 has an integral outer wall. The device includes a support plate 13 that supports one side of the display panel. A mounting groove 14 is formed on one side of the outer wall of the nut plate 12, and a pressing component 16 is installed inside the mounting groove 14. A pump body 15 is bolted to one side of the outer wall of the nut plate 12. The pump body 15 is preferably a DC 12V micro vacuum pump. The pressing component 16 includes two telescopic cylinders 17. A pressure block 18 is bolted to the output end of the two telescopic cylinders 17, and a rubber block 19 is adhered to the bottom side of the pressure block 18. When the pump body 15 is started, air enters the two telescopic cylinders 17, and then the pressure block 18... The rubber block 19 slides inside the mounting groove 14, restricting the edge of the flexible display panel and firmly fixing the display panel with the limiting member 7. Then, the four drive motors 6 are started, and the lead screw 5 moves the limiting member 7 inside the mounting groove 4, pulling the four sides of the panel in all directions, so that the panel unfolds and the wrinkled parts of the panel are pulled open. At the same time, it can also prevent the flexible display panel from sagging at the mounting groove 4 due to gravity, so that the flexible display panel will not have new problems during leveling. The telescopic cylinder 17 is connected to the pump body 15 through the pipe.

[0032] This utility model provides a display panel processing and leveling mechanism. During leveling, the flexible display panel to be leveled can be placed on the base 3 first. Then, four drive motors 6 are started. Subsequently, the drive motors 6 will rotate the corresponding lead screws 5. The rotating lead screws 5 will slide the limiting members 7 inside the mounting groove 4. The four limiting members 7 sliding together can limit the flexible display panel, so that the flexible display panel is centered on the base 3. This achieves the purpose of quickly straightening the flexible display panel, which facilitates the subsequent leveling process and greatly improves the continuous leveling speed of the leveling mechanism.

[0033] In one embodiment provided by this utility model, such as Figure 3 As shown, a groove 8 is provided on one side of the outer wall of the top of the base 3, and a top plate 9 is slidably inserted into the groove 8. A placement area 10 is provided on one side of the outer wall of the base 3, and a lifting cylinder 11 is installed at the center of one side of the inner wall of the placement area 10 by bolts. The lifting cylinder 11 is preferably SC30850. After leveling is completed, the lifting cylinder 11 can be started. When the lifting cylinder 11 is started, the top plate 9 will rise inside the groove 8, so that the top plate 9 lifts the leveled flexible display panel on the base 3, so that the worker can quickly pick up the leveled flexible display panel. The output end of the lifting cylinder 11 is fixedly connected to the outer wall of one side of the top plate 9 by bolts.

[0034] In another embodiment provided by this utility model, such as Figure 6-7 As shown, the upper mold assembly 2 includes two support rods 20. One end of each support rod 20 is bolted to the outer wall of the top two sides of the base 3. A support plate 21 is bolted to one end of each support rod 20. A pressing cylinder 22 is bolted to the center of one outer wall of the support plate 21. The pressing cylinder 22 is preferably an SC40*150. A pressing mold component 23 is bolted to the output end of the pressing cylinder 22. When leveling, the pressing cylinder 22 can be started. Subsequently, the pressing cylinder 22 will lower the upper mold assembly 2, thereby flattening the display panel on the base 3. The pressing mold component 23 includes a pressure plate 24. The output end of the pressing cylinder 22 is fixedly connected to the pressure plate 24 by bolts. The pressure plate 24 has sliding grooves 25 on all four outer walls. A sliding plate 26 is slidably inserted inside the groove 25. A telescopic tube 27 is bolted to one side of the inner wall of the groove 25, and the other end of the telescopic tube 27 is fixedly connected to the sliding plate 26 by bolts. An air pump 28 is installed inside the groove 25. The preferred model of the air pump 28 is a DC12V micro vacuum pump. When the air pump 28 is started, it draws air out of the telescopic tube 27. As the air is drawn out, the telescopic tube 27 will retract, and then the sliding plate 26 will retract into the groove 25 to avoid collision between the sliding plate 26 and the limiting member 7. At the same time, the retracted sliding plate 26 can also flatten the area that the pressure plate 24 cannot press, ensuring the flattening effect of the upper mold assembly 2 on the flexible display panel. The air pump 28 is connected to the four telescopic tubes 27 through pipes.

[0035] Working Principle: During leveling, the flexible display panel to be leveled is first placed on the base 3. Then, the four drive motors 6 are started, and the drive motors 6 drive the corresponding lead screws 5 to rotate. The rotating lead screws 5 cause the limiting members 7 to slide inside the mounting groove 4. The simultaneous sliding of the four limiting members 7 can limit the flexible display panel, making the flexible display panel centered on the base 3, thus achieving the purpose of quickly leveling the flexible display panel. After leveling, the edge of the panel will be stuck inside the mounting groove 14. Then, the pump body 15 is started, and air enters the two telescopic cylinders 17. Then, the pressure block 18 causes the rubber block 19 to slide inside the mounting groove 14, restricting the edge of the flexible display panel and making the display panel firmly fixed by the limiting members 7. Then, the four drive motors 6 are started again, and the lead screws 5 move inside the mounting groove 4 with the limiting members 7, pulling the four sides of the panel outwards, thus unfolding the panel. The panel is opened, causing the wrinkled parts to open up. After leveling, the pressing cylinder 22 can be started. The pressing cylinder 22 will then lower the upper mold assembly 2, thereby flattening the display panel on the base 3. During the pressing process, in order to prevent the sliding plate 26 from affecting the limiting component 7, the air pump 28 can be started. The air pump 28 will draw air out of the telescopic tube 27. As the air is drawn out, the telescopic tube 27 will retract. Then the sliding plate 26 will retract into the slide groove 25 to avoid collision between the sliding plate 26 and the limiting component 7. At the same time, the retracted sliding plate 26 can also flatten the areas that the pressing plate 24 cannot press, ensuring the flattening effect of the flexible display panel. After the flattening is completed, the lifting cylinder 11 can be started. When the lifting cylinder 11 is started, the top plate 9 will rise inside the groove 8, so that the top plate 9 will lift the flattened flexible display panel on the base 3, so that the worker can quickly pick up the flattened flexible display panel.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
