Description

Technical Field

[0001] This application relates to the field of auxiliary equipment technology for optical film production, specifically to an optical sheet sorting device. Background Technology

[0002] Currently, most manufacturers still use manual sorting for optical sheets (such as polarizing plates). Manual sorting has several problems: 1. Low production efficiency; 2. High rate of human error affecting product quality; 3. Difficulty in manually handling large-sized products, easily resulting in defective products, and it does not meet the requirements of automated production lines. Existing sheet sorting machines have some issues: The side-loading material receiving design requires the sheet to be stationary during transfer, and the reverse side requires the main conveyor belt to be stationary, which reduces machine efficiency and output; existing sheet sorting machines achieve the sorting function by switching the position of the main conveyor belt to connect various auxiliary lines, a cumbersome switching process that affects production efficiency, and the quality of the sheet cannot be guaranteed when switching conveyor lines.

[0003] Based on the above, there is an urgent need to develop a solution that can ensure both neat and fast material handling for products of various sizes. Utility Model Content

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0034] like Figure 1 and Figure 2 and Figure 5As shown, this embodiment provides an optical sheet sorting device, which includes a first frame, a second frame, and a third frame. The first frame, the second frame, and the third frame are arranged on a machine base 1. The first frame is equipped with a conveying mechanism 2 and a slitting mechanism 8. The second frame is equipped with a rotating second belt 72, and the third frame is equipped with a rotating third belt 73. The second frame and the third frame are staggered. The slitting mechanism 8 includes a drive body and a movably mounted sun gear 13. The drive body is mounted on the second frame, and the sun gear 13 is movably mounted on the second frame. The drive body drives the sun gear 13 to switch positions so that the second belt 72 or the third belt 73 can cooperate with the conveying mechanism 2. In this embodiment, an OK receiving station 18 is placed at the rear of the third frame, and an NG receiving station 17 is placed at the rear of the second frame.

[0035] As attached Figure 2 and Figure 7 As shown, in this embodiment, the first belt 71, the second belt 72 and the third belt 73 are all provided with a number of honeycomb holes. The first frame, the first frame and the third frame are provided with a suction box 10. The suction box 10 is provided with a number of suction grooves 19, which can adsorb the film material onto the conveyor belt, improve the adhesion of the film material on the conveyor belt, and solve the problem of the product slipping due to gravity on the non-horizontal conveyor belt.

[0036] As attached Figure 3 and Figure 4 In this embodiment, the conveying mechanism 2 includes a first belt 71 rotatably mounted on the first frame. The position of the first frame is adjustable, meaning the position of the first belt 71 is adjustable. The distance between the first frame and the second and third frames is adjustable. The first frame can extend and retract relative to its mounting position. When extended, it works in conjunction with the second and third frames. When retracted, the area between the frames provides maintenance work space for maintenance personnel. A gear set 4 and a fixed rotating shaft are rotatably mounted on one side of the machine base 1. The gear set 4 meshes with the toothed structure on the first frame. A conveyor wheel is rotatably mounted on the other side of the machine base 1. A movable transmission shaft is mounted on the first frame. A guide rail 3 is provided on the machine base 1. The first frame slides on the guide rail 3. The movable transmission shaft, the fixed rotating shaft, and the conveyor wheel sequentially tension the first belt 71. The motor drives the gear set 4 to rotate, driving the first frame to switch positions. The motor driving the gear set 4 to rotate is a mature existing technology and will not be described in detail here.

[0037] As attached Figure 3 As shown, the motor drives the gear set 4 to rotate counterclockwise, and the guide rail 3 fixed on the first frame moves forward. At this time, the first frame is in the extended state, the distance between the moving transmission shaft 5 and the fixed transmission shaft 6 is reduced, and the length of the first belt 71 between the two is reduced. At this time, the first belt 71 and the front section of the second belt 72 are connected.

[0038] like Figure 4As shown, the motor drives the gear set 4 to rotate clockwise, and the guide rail 3 fixed on the first frame moves backward. At this time, the first frame is in a retracted state, the distance between the moving transmission shaft 5 and the fixed transmission shaft 6 increases, the length of the first belt 71 increases, leaving space for the front cutting blade maintenance, that is, the distance between the first belt 71 and the moving transmission shaft 5 and the fixed transmission shaft 6.

[0039] As attached Figure 5 As shown, in this embodiment, the driving body includes a cylinder 14 and a solenoid valve 15. The solenoid valve 15 is connected to the cylinder 14. The cylinder 14 is fixed on the side plate of the second frame or machine base 1. A crossbeam is mounted on the first frame, and a connecting rod 12 is rotatably mounted on the crossbeam. Normally, the connecting rod 12 is an L-shaped rod, with the included end of the connecting rod 12 rotatably mounted on the crossbeam. A sun gear 13 is rotatably mounted on one end of the connecting rod 12. The telescopic rod of the cylinder 14 is rotatably connected to the other end of the connecting rod 12. The telescopic movement of the telescopic rod of the cylinder 14 is converted into the swinging motion of the sun gear 13. It should be noted that the swing amplitude of the sun gear 13 is small, and there is a gap at the connection between the connecting rod 12 and the telescopic rod of the cylinder 14. The connection here uses a hinged connection method, which is sufficient to satisfy the movement of the connecting rod 12.

[0040] The solenoid valve 15 receives the segmentation signal and controls the cylinder 14 to extend and retract. The cylinder 14 extension rod gradually shortens, and the cylinder 14 plays a traction role. The sun wheel 13 on the connecting rod 12 swings. The front section of the second belt 72 and the third belt 73 connect and transport OK products into the OK receiving table 18.

[0041] When the telescopic rod of cylinder 14 extends, the connecting rod 12 swings downward. In this embodiment, when it swings to an angle of 26.52 degrees away from the original position, it is pressed and guided by the sun wheel 13. The front section of the second belt 72 and the rear section of the second belt 7 are connected and conveyed to the NG product flow channel and flow into the NG receiving table 17.

[0042] By separating the OK and NG flow channels and operating them independently, machine 1 can be kept running continuously without stopping to sort OK and NG products, thus improving production efficiency.

[0043] In a further embodiment, the second frame and the third frame are arranged at different heights, so that the second frame in the sorting device is located in an activity area for workers. The device also has two manual auxiliary receiving stations. The two receiving stations are transferred through the slitting mechanism 8. The manual assistance in receiving can reduce the probability of the film material falling into the receiving tray unevenly and causing quality abnormalities.

[0044] As attached Figure 5 and Figure 8As shown, the bottom of the second frame is provided with a segmentation baffle 11, and a blow-up duckbill 16 is fixed at the position of the sun gear on the second frame. In addition, an ion electrostatic bar 9 for removing static electricity is also provided on the second frame. When the blow-up duckbill 16 is working, it blows air upward to facilitate the movement of the optical sheet to the third belt 73. A cylindrical bar is provided on the segmentation baffle 11, which has a guiding function.

[0045] In practical applications on polarizing plate production lines, its large-size sheet taking speed can reach over 60m / min, overcoming the problem of slow speed and waiting time for sheet taking when large-size products are being slit, greatly improving the slitting speed and thus increasing production efficiency; it can increase the sorting capacity of optical film sheets from 35m / min to 60m / min, an increase of 70%.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.
