Abstract
Description
Technical Field
[0001] This utility model relates to the field of polarizer processing technology, and in particular to a material feeding arm and polarizer processing device. Background Technology
[0002] A polarizer, also known as a light polarizer, is an imaging component in liquid crystal displays (LCDs). During polarizer production, after cleaning, the polarizer is transferred from the cleaning platform to the unloading conveyor belt using an unloading arm. To ensure smooth operation of the next process on the unloading conveyor belt, the polarizer's position needs to be adjusted after cleaning and placed on the unloading conveyor belt. Specifically, the distance between adjacent polarizers needs to be increased, and the angle of the polarizer needs to be changed to meet the requirements of subsequent processes.
[0003] In related technologies, the unloading arm includes a drive mechanism, a linkage mechanism, and at least two rotating mechanisms. The at least two rotating mechanisms are slidably mounted on the base in the same direction. Each pair of rotating mechanisms is connected by a linkage mechanism. The drive mechanism drives the linkage mechanism to rotate and slide relative to the base, causing the two rotating mechanisms to move closer or further apart, thereby reducing or increasing the spacing between adjacent polarizers. Because the linkage mechanism of this unloading arm is subjected to significant forces, it is prone to damage and requires frequent replacement and maintenance. However, the complex structure of the linkage mechanism leads to prolonged maintenance time, severely impacting production efficiency and equipment uptime. Utility Model Content
[0004] The purpose of this utility model is to provide a feeding arm and polarizer processing device, which can adjust the position of the polarizer, has a simple structure, short maintenance time, and improves production efficiency and equipment uptime.

[0007] Base
[0008] A drive mechanism is provided on the base. The drive mechanism includes a drive assembly and two sets of transmission assemblies. Each set of transmission assemblies includes a synchronous belt and two synchronous pulleys. The two ends of the synchronous belt are respectively sleeved on the two synchronous pulleys. The drive assembly is used to drive one of the synchronous pulleys in each set of transmission assemblies to rotate. In the two sets of transmission assemblies, one synchronous belt surrounds the other synchronous belt.
[0009] Four rotating gripping mechanisms are slidably disposed on the base along the first direction. The rotating gripping mechanisms are used to grip and rotate the polarizer. Two of the rotating gripping mechanisms are respectively disposed on both sides of one of the synchronous belts, and the other two rotating gripping mechanisms are respectively disposed on both sides of the other synchronous belt. Each synchronous belt can drive the corresponding two rotating gripping mechanisms to move closer to or further away from each other along the first direction.

[0011] In some possible implementations, all four rotary gripping mechanisms are located at the bottom of the drive mechanism, and the unloading arm further includes a first connecting member. All four rotary gripping mechanisms are fixedly connected to the corresponding timing belts through the first connecting member.
[0012] In some possible implementations, the drive component is tunably positioned on the base along the first direction.
[0013] In some possible implementations, the drive mechanism further includes a slider and a screw, the drive assembly is fixed to the slider, the base is provided with a sliding hole, the screw passes through the hole wall of the sliding hole and is connected to the slider, and the screw is threadedly connected to the hole wall of the sliding hole. When the screw is turned, the slider can slide in the sliding hole along the first direction.
[0014] In some possible implementations, the base is provided with two buffers spaced apart along the first direction, and all four rotating gripping mechanisms are located between the two buffers; and / or,
[0015] The base is provided with two limiters spaced apart along the first direction, and the four rotating gripping mechanisms are all located between the two limiters. The limiters are communicatively connected to the drive assembly.
[0016] In some possible implementations, the rotating gripping mechanism includes a rotating component and a suction cup component. The rotating component is slidably disposed on the base along the first direction, and the suction cup component is disposed at the output end of the rotating component. The rotating component is used to drive the suction cup component to rotate, and the suction cup component is used to adsorb the polarizer.
[0017] In some possible implementations, the rotating assembly includes a mounting base, a rotary motor, a metal plate, and a sensor. The rotary motor and the sensor are both fixed to the mounting base, and the metal plate is fixed to the output shaft of the rotary motor. The metal plate can trigger the sensor to detect the rotation angle of the suction cup assembly.
[0018] In some possible implementations, the base is provided with a guide rail that extends along the first direction, and all four rotating gripping mechanisms are slidably connected to the guide rail.
[0019] On the other hand, a polarizer processing apparatus is provided, including a transverse moving arm and a feeding arm as described in any of the above embodiments, wherein the base is fixed to the transverse moving arm.
[0020] The beneficial effects of this utility model are:
[0021] The unloading arm provided by this utility model includes a base, a drive mechanism, and four rotary gripping mechanisms. When moving the polarizer from the cleaning platform to the unloading conveyor belt, the drive assembly drives one synchronous pulley in each transmission assembly to rotate, thereby driving two synchronous belts.

Furthermore, the use of synchronous belts to drive the rotary gripping mechanisms results in a simple structure, shorter maintenance time, and improved production efficiency and equipment uptime.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0031] like Figures 1 to 3 As shown, this utility model provides a material unloading boom, including a base 1, a drive mechanism, and four rotating gripping mechanisms 4. The drive mechanism is disposed on the base 1 and includes a drive assembly 2 and two sets of transmission assemblies 3. Each set of transmission assemblies 3 includes a synchronous belt 31 and two synchronous pulleys 32. The two ends of the synchronous belt 31 are respectively sleeved on the two synchronous pulleys 32. The drive assembly 2 is used to drive one of the synchronous pulleys 32 in each set of transmission assemblies 3 to rotate. In the two sets of transmission assemblies 3, one synchronous belt 31 surrounds the other synchronous belt 31. Here, the surrounding can be such that one synchronous belt 31 is directly opposite the other synchronous belt 31. The projections of the synchronous belts 31 on the horizontal plane coincide, or one synchronous belt 31 may be diagonally opposite the other synchronous belt 31, and the projections of the two synchronous belts 31 on the horizontal plane may not coincide. The four rotating gripping mechanisms 4 are all slidably disposed on the base 1 along the first direction, which is the length direction of the base 1. The rotating gripping mechanisms 4 are used to grip and rotate the polarizer. Two of the rotating gripping mechanisms 4 are respectively disposed on both sides of one of the synchronous belts 31, and the other two rotating gripping mechanisms 4 are respectively disposed on both sides of the other synchronous belt 31. Each synchronous belt 31 can drive the corresponding two rotating gripping mechanisms 4 to move closer to or further away from each other along the first direction.
[0032] When the polarizer is moved from the cleaning platform to the unloading conveyor belt, the drive assembly 2 drives one of the synchronous pulleys 32 in each transmission assembly 3 to rotate, which in turn drives two synchronous belts 31 to move. The two synchronous belts 31 can drive the corresponding two rotary gripping mechanisms 4 to move away from each other along the first direction, increasing the distance between the four rotary gripping mechanisms 4 until the distance between the four rotary gripping mechanisms 4 is equal. Then, the rotary gripping mechanism 4 rotates the polarizer to a set angle and places the polarizer on the unloading conveyor belt. By surrounding one synchronous belt 31 with another synchronous belt 31, and placing two rotary gripping mechanisms 4 on either side of one synchronous belt 31 and the other two rotary gripping mechanisms 4 on either side of the other synchronous belt 31, the four rotary gripping mechanisms 4 can be moved closer or further apart along the first direction, thus adjusting the distance between the polarizers. In addition, the structure is relatively simple, the maintenance time is short, and the production efficiency and equipment uptime are improved by using the synchronous belts 31 to drive the rotary gripping mechanisms 4.
[0033] Optionally, the base 1 is provided with a guide rail 12, which extends along the first direction, and the four rotating gripping mechanisms 4 are all slidably connected to the guide rail 12. By providing the guide rail 12, the sliding of the four rotating gripping mechanisms 4 is guided, and the four rotating gripping mechanisms 4 are also prevented from falling off the base 1.
[0034] Optionally, in the two sets of transmission components 3, two synchronous pulleys 32 are rotatably connected to the first rotating shaft 33. Further, two synchronous pulleys 32 are rotatably connected to the first rotating shaft 33 via bearings, and the first rotating shaft 33 is fixed to the base 1. The other two synchronous pulleys 32 are disposed on a second rotating shaft 34, which is rotatably connected to the base 1. The drive component 2 is used to drive the second rotating shaft 34 to rotate, thereby causing the two synchronous pulleys 32 to rotate synchronously. The above arrangement pertains to a situation where one synchronous belt 31 is obliquely opposite the other, and the projections of the two synchronous belts 31 on the horizontal plane do not coincide. With two synchronous pulleys 32 rotatably connected to the first rotating shaft 33 and the other two synchronous pulleys 32 disposed on the second rotating shaft 34, synchronous rotation of the two synchronous pulleys 32 can be achieved, improving the accuracy of adjusting the polarizer spacing and simplifying the structure of the unloading arm, thus reducing its space requirement. When one synchronous belt 31 is directly opposite the other synchronous belt 31, and the projections of the two synchronous belts 31 on the horizontal plane coincide, two sets of drive components 2 can be set. The two sets of drive components 2 are set one-to-one with the two sets of transmission components 3, and each set of drive components 2 drives the corresponding synchronous pulley 32 to rotate.
[0035] Optionally, all four rotary gripping mechanisms 4 are located at the bottom of the drive mechanism. The unloading arm also includes a first connecting member 5. Each of the four rotary gripping mechanisms 4 is fixedly connected to its corresponding synchronous belt 31 via the first connecting member 5. The location of the four rotary gripping mechanisms 4 at the bottom of the drive mechanism facilitates the maintenance and replacement of the synchronous belt 31. The connection between the four rotary gripping mechanisms 4 and their corresponding synchronous belts 31 via the first connecting member 5 is convenient. Specifically, the first connecting member 5 corresponding to one rotary gripping mechanism 4 is a horizontal sheet metal, fixedly connected to the bottom side of the outer synchronous belt 31. The first connecting members 5 corresponding to the other three rotary gripping mechanisms 4 are U-shaped sheet metal, with one end connected to the synchronous belt 31 and the other end connected to the rotary gripping mechanism 4. Specifically, the first connecting member 5 is connected to the synchronous belt 31 via a second connecting member 35. Furthermore, the second connecting member 35 is a square sheet metal.
[0036] Optionally, the drive assembly 2 is adjustablely positioned on the base 1 along the first direction. This configuration ensures that the tension of the synchronous belt 31 meets the drive requirements. Optionally, the drive mechanism also includes a slider 6 and a screw 7. The drive assembly 2 is fixed to the slider 6. The base 1 has a sliding hole 11. The screw 7 passes through the hole wall of the sliding hole 11 and is fixedly connected to the slider 6. The screw 7 is threadedly connected to the hole wall of the sliding hole 11. When the screw 7 is turned, the slider 6 can slide within the sliding hole 11 along the first direction. This configuration facilitates the adjustment of the position of the drive assembly 2 and improves the accuracy of the adjustment position. Further, to ensure a reliable connection, the slider 6 has an oblong hole 61. The base 1 has multiple fixing holes 13 spaced apart along the first direction. Fasteners pass through the oblong hole 61 and are threadedly connected to one of the fixing holes 13. Optionally, the drive assembly 2 includes a mounting bracket 21 and a drive motor 22. The drive motor 22 is fixed to the slider 6 via the mounting bracket 21.
[0037] Optionally, the base 1 is provided with two buffers 8 spaced apart along the first direction, and the four rotating gripping mechanisms 4 are all located between the two buffers 8. The buffers 8 prevent the rotating gripping mechanisms 4 from impacting the base 1. Optionally, the base 1 is provided with two limiters 9 spaced apart along the first direction, and the four rotating gripping mechanisms 4 are all located between the two limiters 9. The limiters 9 are communicatively connected to the drive assembly 2. The limiters 9 limit the extreme positions of the rotating gripping mechanisms 4. When the rotating gripping mechanism 4 reaches its extreme position and triggers the limiter 9, the drive assembly 2 stops operating. The buffers 8 and limiters 9 are mature technologies in related fields, and will not be described in detail in this embodiment.
[0038] Optionally, the rotating gripping mechanism 4 includes a rotating component 41 and a suction cup component 42. The rotating component 41 is slidably disposed on the base 1 along a first direction, and the suction cup component 42 is disposed at the output end of the rotating component 41. The rotating component 41 is used to drive the suction cup component 42 to rotate, and the suction cup component 42 is used to adsorb the polarizer. This configuration allows for adjustment of the rotation angle of the polarizer, and by adsorbing the polarizer with a suction cup, damage to the polarizer can be avoided.
[0039] Furthermore, such as Figure 3As shown, the rotating assembly 41 includes a mounting base 411, a rotary motor 412, a metal plate 413, and a sensor. The rotary motor 412 and the sensor are both fixed to the mounting base 411. The metal plate 413 is fixed to the output shaft of the rotary motor 412. The metal plate 413 can trigger the sensor to detect the rotation angle of the suction cup assembly 42. Specifically, the sensor is fixed to the mounting base 411 via a bracket 414. This arrangement facilitates the detection of the rotation angle of the suction cup assembly 42 and ensures the accuracy of the rotation angle. Specifically, the rotary motor 412 is a dual-axis motor. The metal plate 413 is fixed to one output shaft of the dual-axis motor, and the other output shaft of the dual-axis motor is fixedly connected to the suction cup assembly 42 via a coupling 415.
[0040] This utility model also provides a polarizer processing device, including a transverse moving arm and a feeding arm. A base 1 is fixed to the transverse moving arm, which drives the feeding arm to reciprocate between the cleaning platform and the feeding conveyor belt. When this polarizer processing device moves the polarizer from the cleaning platform to the feeding conveyor belt, it can adjust the position of the polarizer. The structure is relatively simple, maintenance time is short, and production efficiency and equipment uptime are improved. For example, after the polarizer is cleaned on the cleaning platform, the transverse moving arm moves the feeding arm from the cleaning platform to above the feeding conveyor belt. The drive assembly 2 drives two synchronous belts 31 to move, causing the four rotating gripping mechanisms 4 to move away from each other. After moving to a set position, the rotating gripping mechanism 4 rotates the suction cup assembly 42 by 90 degrees to change the angle of the polarizer. Finally, the suction cup assembly 42 releases the polarizer onto the feeding conveyor belt, which then transports it to the next process.
[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
