Description

Technical Field

[0001] The utility model belongs to the technical field of optical film production, and in particular relates to a device for removing residual adhesive at the edge of an optical film. Background Art

[0002] With the widespread application of optical films in electronic products, displays, optical instruments and other fields, the processing requirements for optical films in the production process are becoming increasingly higher. Among them, in order to give the original materials of the optical film new functions, it is often common practice to compound multiple layers of diaphragms during the production process. However, some glue substances often remain on the edges of the optical film. If these residual glues are not effectively removed, they will affect the quality, performance and subsequent application effects of the optical film.

[0003] Among them, the existing documents disclose a side cleaning mechanism for optical film raw materials, which mainly solves the following problems: the side cleaning mechanism for optical film raw materials, the low efficiency of manual cleaning of the sides of the raw materials, and the easy residue of glue marks. However, it is found in the long-term use process that in order to ensure the effective contact of the cleaning part with the edge of the film, the elastic parts added during operation may cause warping when the optical film swings slightly. In addition, its flexibility in adjusting according to the specifications of the optical film is also poor. For this reason, practitioners have designed a device for removing residual glue on the edge of the optical film. Utility Model Content

[0004] The purpose of the present utility model is to provide a device for removing residual adhesive from the edge of an optical film in order to solve the problems of the existing device for removing residual adhesive from the edge of an optical film, which easily causes the edge of the optical film to warp during the cleaning process and has low flexibility in adjusting the specifications of the optical film before work.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions: a device for removing residual adhesive from the edge of an optical film, comprising a discharger, a guide roller rotatably provided on the side wall of the discharger, two groups of extension rods provided on the side wall of the discharger above the guide roller, and residual adhesive removal devices provided at the ends of the two groups of extension rods;

[0006] The residual glue removal device includes a device body, a guide rail is provided on the device body, two groups of sliders are slidably provided on the guide rail, both groups of sliders are provided with a base, a locking piece is provided at the bottom of the base located on one side of the slider, a locking wrench that cooperates with the guide rail is provided on the outer wall of the locking piece, and both groups of bases are provided with residual glue removal components.

[0007] Furthermore, the length of the extension rod is greater than the length of the guide roller.

[0008] Furthermore, two sets of limiting members are provided on the upper surface of the device body at both ends of the guide rail;

[0009] The limiting member includes a limiting bottom plate, and a cylindrical rubber block is arranged on the limiting bottom plate.

[0010] Furthermore, the residual glue removal component includes a residual glue removal base plate arranged on the base, a pressure plate is arranged on the residual glue removal base plate through a torsion spring, and cleaning sponges are provided on the residual glue removal base plate and the inner wall of the pressure plate, and two groups of cleaning sponges are arranged in relative cooperation.

[0011] Furthermore, the residual glue removal component includes a residual glue removal base plate arranged on the base, and two groups of epitaxial columns are provided on a sliding sleeve at one end of the residual glue removal base plate. The residual glue removal base plate and the epitaxial columns are matched with each other through locking bolts, and pressure plates are provided on the two groups of epitaxial columns. Cleaning sponges are provided on the residual glue removal base plate and the inner wall of the pressure plate, and the two groups of cleaning sponges are arranged relative to each other.

[0012] Beneficial effects: The utility model has reasonable design, simple and stable structure, strong practicality, and has the following beneficial effects:

[0013] 1. Efficient adhesive removal: The design of the device ensures that two sets of adhesive removal components can efficiently remove adhesive residue from the edge of the optical film through cleaning sponges.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1:

[0026] Combine Figure 1-2 The device for removing residual adhesive from the edge of an optical film shown in the figure includes a feeder 1. The feeder 1 serves as the main carrier of the optical film raw material. A guide roller 2 is rotatably provided on the side wall of the feeder 1. The guide roller 2 is used to guide the direction of the optical film raw material so that it can effectively enter the subsequent device. Two groups of extension rods 3 are provided on the side wall of the feeder 1 above the guide roller 2. The extension rods 3 play a supporting role. The length of the extension rods 3 is greater than that of the guide roller 2, providing sufficient space between the guide roller 2 and the residual adhesive removal device, thereby enhancing the stability of the entire device and reducing errors caused by film movement during operation. The ends of the two groups of extension rods 3 are provided with residual adhesive removal devices 4;

[0027] The residual glue removal device 4 includes a device body 401, which is the core frame of the entire residual glue removal device 4 and supports all other components. A guide rail 402 is provided on the device body 401 to provide a sliding path. Two groups of sliders 403 are slidingly provided on the guide rail 402. Both groups of sliders 403 are provided with a base 404 for carrying and stabilizing the residual glue removal component 407. A locking piece 405 is provided at the bottom of the base 404 located on one side of the slider 403. A locking wrench 406 that cooperates with the guide rail 402 is provided on the outer wall of the locking piece 405. The locking wrench 406 is adjusted and fixed to ensure the position and firmness of the base 404 on the guide rail, so that the two groups of residual glue removal components 407 can adapt to optical films of different specifications. Both groups of bases 404 are provided with residual glue removal components 407.

[0028] Combine Figure 3As shown, two sets of limit members 408 are provided on the upper surface of the device body 401 at both ends of the guide rail 402. The limit members 408 are used to limit the operating positions of the two sets of sliders 403 to prevent them from detaching from the guide rail 402.

[0029] The limiting member 408 includes a limiting base plate 4081, on which a cylindrical rubber block 4082 is provided. The limiting base plate 4081 serves as the main bearing platform of the rubber block 4082. The rubber block 4082 has excellent elasticity and buffering properties and can effectively absorb the vibration and impact generated by the device during operation.

[0030] Combine Figure 4 The residual glue removal assembly 407 shown includes a residual glue removal base plate 4071 arranged on the base 404, and a pressure plate 4072 is arranged on the residual glue removal base plate 4071 through a torsion spring. The torsion spring not only enables the pressure plate 4072 to apply uniform pressure, but also allows the pressure plate 4072 to be fine-tuned according to actual needs during operation to ensure that it applies appropriate pressure to the edge of the optical film. The residual glue removal base plate 4071 and the inner wall of the pressure plate 4072 are both provided with cleaning sponges 4073. The cleaning sponges 4073 have high adsorption capacity and can effectively capture and remove residual glue on the edge of the film. The two groups of cleaning sponges 4073 are arranged in relative coordination to form a tight cleaning area to ensure the thorough removal of the glue. The relative coordination between the two sponges improves the cleaning efficiency and reduces the residual glue through the dual effects of squeezing and adsorption.

[0031] Embodiment 2: The residual adhesive removal component 407 in the embodiment 2 is improved on the basis of the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly. The contents of the above disclosed embodiment also belong to the contents disclosed in the embodiment 2.

[0032] One embodiment of the present invention, combined with Figure 5The residual glue removal assembly 407 shown includes a residual glue removal base plate 4071 provided on the base 404, and a sliding sleeve is provided at one end of the residual glue removal base plate 4071 with two groups of epitaxial columns 4074. The residual glue removal base plate 4071 and the epitaxial columns 4074 are matched with each other through locking bolts 4075. A pressure plate 4072 is provided on the two groups of epitaxial columns 4074. The inner walls of the residual glue removal base plate 4071 and the pressure plate 4072 are both provided with cleaning sponges 4073. The two groups of cleaning sponges 4073 are relatively matched. An adjustable extension column 4074 replaces the torsion spring of Example 1. In this way, the gap can be fine-tuned by itself, and then the adjusted position is fixed by the locking bolt 4075, so as to cope with optical films of different thicknesses and ensure the best degumming effect under various operating conditions. Although this Example 2 can more carefully ensure the spacing between the two sets of cleaning sponges 4073 and avoid the problem of poor operation caused by the large force of the torsion spring, this method is more time-consuming during the adjustment process.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
