Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic polarizer connection, specifically an automatic connection device for slitting roll polarizers. Background Technology
[0002] Polarizers are an indispensable component for LCD imaging. With the increasing demand for LCD monitors (TVs, notebooks, mobile devices, etc.) in recent years, the demand for polarizers has also increased significantly. The manufacturing process of polarizers is relatively complex, and the slitting process of roll polarizers is a crucial step. Ensuring the quality of the reconnection after slitting is particularly important. Currently, the methods for connecting roll polarizers after slitting include manual connection and fixture-assisted automated connection.
[0003] The advantages of jig-assisted automatic connection over manual connection are: the cut is smooth, the connection gap is small, and the tape is less likely to produce defects such as wrinkles and bubbles after application.
[0004] Currently, the automatic connection of roll polarizing film after slitting is done manually, which cannot guarantee the quality of the connection and leads to poor air marks on the protective film. Since the position, quantity, and width of the roll material are not fixed after slitting, it is impossible to add a fixing device to the production line for connection. Utility Model Content
[0005] The purpose of this invention is to provide an automatic connection device for slitting roll polarizers to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automatic connection device for slitting roll-shaped polarizing films, characterized in that it includes a rotating connection platform, a tape adsorption plate, and a connection frame. The rotating connection platform is mounted on the connection frame, and a vacuum adsorption assembly is provided on the rotating connection platform. The vacuum adsorption assembly has several vacuum adsorption holes. Vacuum adsorption assemblies are provided on both the upper and lower opposing surfaces of the rotating connection platform. A slit is provided along the axial direction in the middle of the vacuum adsorption assembly. A bearing is connected to one end of the rotating connection platform, and a rotating cylinder is connected to the other end. The tape adsorption plate is provided on the side of the connection frame away from the rotating connection platform. The tape adsorption plate is provided on one side of the rotating connection platform.
[0007] Furthermore, a support frame is provided below the rotating connection platform. One end of the support frame is fixedly connected to the connection frame. The length of the support frame is longer than that of the rotating connection platform. The support frame and the connection points of the rotating connection platform and the connection frame are located at the same vertical position. The part of the support frame that is longer than the rotating connection platform extends upward and is equipped with a bearing. A connecting shaft is provided at the end of the rotating connection platform away from the connection frame. This connecting shaft is fixedly connected to the bearing on the support frame.
[0008] Furthermore, the tape adsorption plate is equipped with several tape adsorbers, which are set at different horizontal positions.
[0009] Furthermore, the device is equipped with a movable base at the bottom, and the movable base is equipped with several casters.
[0010] Compared with the prior art, this utility model has the following advantages:
[0011] This utility model utilizes a device to cut the interface, which can guarantee 100% neatness of the cut and prevent unevenness.
[0012] This utility model uses a tape fixing device to apply the tape across its full width, ensuring that the tape is neat and wrinkle-free at the joints, and preventing secondary defects caused by later curling. Attached Figure Description

[0015] Reference Figure 1 The present invention provides an embodiment of an automatic connection device for slitting roll polarizers, comprising a rotating connection platform 100, a tape adsorption plate 200, and a connection frame 300. The rotating connection platform 100 is disposed on the connection frame 300, and a vacuum adsorption component 110 is disposed on the rotating connection platform 100. The vacuum adsorption component 110 is provided with a plurality of vacuum adsorption holes, which can be controlled to open or close the adsorption function to adsorb the polarizer or tape onto the vacuum adsorption component 110.
[0016] Reference Figure 1 Vacuum adsorption components 110 are provided on the upper and lower surfaces of the rotating connection platform 100. Both surfaces have independently controllable vacuum adsorption functions and can adsorb polarizing film or tape.
[0017] Reference Figure 1 The vacuum adsorption component 110 has a slit 120 in the middle along the axial direction. The reserved slit 120 can ensure that the cut is neat when the blade is cut and will not produce unevenness.
[0018] Reference Figure 1A support frame is provided below the rotating connecting platform 100. One end of the support frame is fixedly connected to the connecting frame 300. The length of the support frame is longer than that of the rotating connecting platform 100. The connection points of the support frame, the rotating connecting platform 100, and the connecting frame 300 are located at the same vertical position. The portion of the support frame longer than the rotating connecting platform 100 extends upward and is equipped with a bearing. A connecting shaft is provided at the end of the rotating connecting platform 100 away from the connecting frame 300. This connecting shaft is fixedly connected to the bearing on the support frame, and the other end is connected to a rotary cylinder 130. The rotary cylinder 130 can drive the rotating connecting platform 100 to rotate around its axis.
[0019] Reference Figure 1 A tape adsorption plate 200 is provided on the side of the connecting frame 300 away from the rotating connecting platform 100. Several tape adsorbers are provided on the tape adsorption plate 200, which are set at different horizontal positions to pre-place tape at different positions to meet different needs and facilitate tearing.
[0020] Reference Figure 1 The device has a movable base 400 at the bottom, and several pulleys on the movable base 400 to allow the device to move freely.
[0021] Example 1: First, manually tear off the required length of tape from the tape adsorption plate 200. Place the smooth, non-sticky side of the tape on the vacuum adsorption component 110 of the rotating connection platform 100. At this time, open the vacuum adsorption hole in this part to adsorb the tape. Activate the rotating cylinder 130 to rotate the rotating connection platform 100 180 degrees. After completing the above operation, move an automatic connection device for slitting and connecting rolls of polarizer film to the middle of the two rolls of polarizer film to be connected via the movable base 400. Place the two rolls of polarizer film on the rotating connection platform 100 respectively. Open the vacuum adsorption hole on this side of the vacuum adsorption component 110 to adsorb the two rolls of polarizer film placed on the vacuum adsorption component 110. After adsorption is complete, tighten the two rolls of polarizing film separately and pull them taut. At this time, use a blade to cut through the slit 120. After that, clean up the cut polarizing film. Then, tear the required length of tape from the tape adsorption plate 200 and attach it to the cut ends of the two rolls of polarizing film. After attachment, close the vacuum adsorption hole of the vacuum adsorption component 110 on this side. The two rolls of polarizing film connected by the tape are tightly wound and slightly raised. At this time, turn on the rotary cylinder 130 to rotate the rotary connection platform 100 180 degrees. Rotate the tape initially attached to the rotary connection platform 100 to the top and then lower the two rolls of polarizing film above to contact the tape, completing the attachment. The double-sided tape attachment is complete. The device is removed, and the automatic connection is completed.
