Description

Technical Field:

[0001] The utility model relates to a cutting device for preparing polarizing plates. Background Art:

[0002] The full name of a polarizing plate is a polarized light plate. The imaging of a liquid crystal display must rely on polarized light. All liquid crystals have two polarized light plates, front and back, closely attached to the liquid crystal glass, forming a liquid crystal sheet with a total thickness of about 1 mm, which is an essential component in liquid crystal imaging technology.

[0003] Most polarizing plates are cut by laser. When cutting a whole roll of polarizing plates, the polarizing plate needs to be fixed on the cutting table. Since the polarizing plate is relatively thin, it is difficult to fix it. Traditional cutting devices often cause the polarizing plate to shift due to insecure clamping, resulting in deviations in the shape and size of the cut polarizing plate, thus affecting the subsequent use of the polarizing plate. Currently, there are also some methods that use downward pressure to fix the polarizing plate, but due to the thin thickness of the polarizing plate, the downward pressure method is likely to damage the polarizing plate. Summary of the Utility Model:

[0004] The utility model makes improvements to the above-mentioned existing technical problems, that is, the technical problem to be solved by the utility model is to provide a cutting device for preparing polarizing plates.

[0005] To achieve the above object, the technical solution adopted by the utility model is: a cutting device for preparing polarizing plates, including a cutting workbench, a laser cutting head arranged above the cutting workbench, and a reel installed at the left end of the cutting workbench and wound with a polarizing plate. A moving long groove is arranged on the cutting workbench directly below the laser cutting head. A moving adsorption seat is slidably connected to the moving long groove and is used for adsorbing the bottom of the polarizing plate and pulling the polarizing plate to move from left to right. A liftable adsorption plate for adsorbing the top of the polarizing plate is horizontally arranged on the left side of the laser cutting head.

[0006] Further, a plurality of first adsorption holes are evenly distributed on the top of the moving adsorption seat, and a plurality of second adsorption holes are evenly distributed on the bottom of the adsorption plate.

[0007] Further, the moving long groove extends horizontally, and transverse chutes are arranged on the front and rear side walls of the moving long groove. The front and rear ends of the moving adsorption seat are respectively slidably matched with the transverse chutes, and the lower end of the moving adsorption seat is connected to a horizontally arranged ball screw nut pair, and the ball screw nut pair drives the moving adsorption seat to move left and right along the transverse chutes.

[0008] Further, the adsorption plate is driven to lift by a lifting cylinder vertically arranged above it.

[0009] Further, both the moving adsorption seat and the adsorption plate are rectangular.

[0010] Compared with the prior art, the utility model has the following effects: The utility model has a reasonable structural design. The moving adsorption seat is used to adsorb the polarizer and pull the polarizer to move from left to right to the right side of the laser cutting head. Then, the adsorption plate adsorbs the top of the polarizer from the left side of the laser cutting head. The upper and lower adsorptions cooperate to fix the polarizer, which is convenient for the laser cutting head to accurately cut the polarizer. At the same time, the adsorption and fixation method is not easy to damage the polarizer. Brief Description of the Drawings:

[0018] The following further describes the utility model in detail with reference to the drawings and specific embodiments.

[0019] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0020] As Figures 1 to 7As shown in the figure, a cutting device for preparing a polarizer according to the present utility model includes a horizontally arranged cuboid-shaped cutting workbench 1, a laser cutting head 2 longitudinally arranged directly above the middle of the cutting workbench 1, and a reel 4 installed at the left end of the cutting workbench 1 and wound with a polarizer 3. A moving long groove 5 is provided on the cutting workbench 1 directly below the laser cutting head 2. The moving long groove extends horizontally (in the left-right direction). A moving adsorption seat 6 is slidably connected in the moving long groove 5. The moving adsorption seat 6 is used to adsorb the bottom of the polarizer 3 and pull the polarizer 3 to horizontally move from left to right through the laser cutting head 2. A liftable adsorption plate 7 for adsorbing the top of the polarizer 3 is horizontally arranged on the left side of the laser cutting head 2.

[0021] During operation, the polarizer 3 drawn from the reel 4 is placed on the top of the moving adsorption seat 6. The moving adsorption seat 6 adsorbs the bottom of the polarizer 3. At this time, the adsorption plate 7 and the moving adsorption seat 6 are vertically opposite to each other. The adsorption plate 7 is located above the polarizer 3, as Figure 4 shown; then the moving adsorption seat 6 horizontally moves to the right. The moving adsorption seat 6 pulls the polarizer 3 to horizontally move from left to right through the laser cutting head 2 until the moving adsorption seat 6 is located on the right side of the laser cutting head 2. Then the adsorption plate 7 descends and adsorbs the top of the polarizer 3, as Figure 5 shown; then the laser cutting head 2 cuts the polarizer, as Figure 6 shown; after cutting is completed, the adsorption plate 7 remains adsorbed to the polarizer to be cut, while the moving adsorption seat 6 drives the cut polarizer to continue moving to the right, facilitating the subsequent removal of the polarizer on the moving adsorption seat 6, as Figure 7 shown; after a cutting operation is completed, the moving adsorption seat 6 moves to the left to the initial state. Then the moving adsorption seat 6 re-adsorbs the bottom of the polarizer 3 to be cut, and the adsorption plate 7 disconnects the adsorption of the polarizer and moves upward. The moving adsorption seat adsorbs the polarizer and pulls the polarizer to move from left to right to the right side of the laser cutting head. Then the adsorption plate adsorbs the top of the polarizer from the left side of the laser cutting head. The upper and lower adsorption cooperate to firmly fix the polarizer, facilitating the laser cutting head to accurately cut the polarizer. At the same time, the adsorption fixing method is not likely to damage the polarizer.

[0022] In this embodiment, a plurality of first adsorption holes 8 are evenly distributed on the top of the moving adsorption seat 6, and the plurality of first adsorption holes are arranged in a matrix; a plurality of second adsorption holes 9 are evenly distributed on the bottom of the adsorption plate 7, and the plurality of second adsorption holes are arranged in a matrix.

[0023] In this embodiment, transverse chutes are provided on both the front and rear sidewalls of the moving long slot 5; the front and rear ends of the moving adsorption seat 6 are respectively inserted into the transverse chutes on the same side and are slidably engaged with the transverse chutes. The lower end of the moving adsorption seat 6 is connected to a horizontally arranged ball screw nut pair 10, and the ball screw nut pair 10 drives the moving adsorption seat 6 to move left and right along the transverse chute. The ball screw nut pair is a mature existing product, which is convenient for controlling the movement of the moving adsorption seat.

[0024] In this embodiment, the adsorption plate 7 is driven by a lifting cylinder 11 vertically arranged above it to lift vertically.

[0025] In this embodiment, both the moving adsorption seat 6 and the adsorption plate 7 are rectangular.

[0026] In this embodiment, connecting brackets 12 are fixed on both the front and rear sides of the left end of the cutting workbench, and the reel 4 is rotatably installed on the connecting brackets 12.

Of course, the mutual fixed connection can also be replaced by an integral structure (such as being integrally formed by a casting process) (except where it is obviously impossible to adopt the integral forming process).

[0028] In addition, the terms used to represent positional relationships or shapes in any of the technical solutions disclosed in the present utility model, unless otherwise stated, include states or shapes that are approximate, similar, or close to them.
