Description

Technical Field

[0001] The utility model belongs to the technical field of OCA optical adhesives, and in particular relates to an OCA punching machine with a PE release film. Background Art

[0002] OCA optical adhesive is a special adhesive used to bond transparent optical components. It is required to be colorless and transparent, with a light transmittance of more than 95%, good bonding strength, can be cured at room temperature or medium temperature, and has small curing shrinkage. OCA optical adhesive is one of the important raw materials for touch screens.

[0003] During the production and processing of OCA optical adhesive, it is necessary to cut it. When the existing punching equipment is in use, residual glue will adhere to the cutting knife. The cutting knife with residual glue will cause damage to the cut surface during the cutting process of OCA optical adhesive. In response to the above technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent publication number CN117047853A. When in use, the spring pushes the cleaning block to contact the cutting knife and remove the glue. However, since the position of the cleaning block is limited by the spring, when encountering relatively strong residual glue, the cleaning block may pass over, making it difficult to ensure the cleaning effect of the cutting knife. In addition, the residual glue accumulated on the cleaning block may fall down on the OCA optical adhesive during the punching process, which is not conducive to punching. Utility Model Content

[0004] The utility model aims to provide an OCA punching machine with a PE release film, aiming to solve the technical problems in the prior art that it is difficult to ensure the cleaning effect of the punching knife and residual glue falls on the OCA optical glue to affect the punching.

[0005] The utility model is implemented as follows: an OCA punching machine with a PE release film comprises a bottom plate, an H-shaped bracket is provided on the bottom plate, a first telescopic member for driving the bracket to move up and down is fixedly installed on the bottom plate, two groups of pressing plates are slidably installed on the bracket, a second telescopic member is fixedly installed on the pressing plate and the second telescopic member drives a mounting frame to move, a rotating shaft is rotatably installed in the mounting frame and a plurality of groups of punching knives are fixedly installed on the rotating shaft, a first rotating power member for driving the rotating shaft to rotate is fixedly installed on the mounting frame, and a cleaning component for cleaning residual glue on the punching knives is provided on the mounting frame.

[0006] Further technical solution: the punching cutters are provided in four groups and distributed in a circular array around the rotating axis.

[0007] Further technical solution: The cleaning assembly includes a collection box, which is slidably mounted on the mounting frame through two sets of sliding rods, and the side of the collection box close to the mounting frame is an open structure, and a third telescopic member is fixedly mounted on the mounting frame to drive the collection box to move.

[0008] Further technical solution: A support plate for supporting the fallen residual glue is slidably installed at the bottom of the collection box, and the support plate passes through one side wall of the collection box.

[0009] Further technical solution: a screw is rotatably installed in the collection box, and a second rotating power component that drives the screw to rotate is fixedly installed on the collection box, and the screw drives the scraper to move.

[0010] Further technical solution: the cross-sectional shape of the scraper is consistent with the cross-sectional shape of the cutting edge of the punching knife.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. Through multiple sets of punching knives, the residual glue adhering to the previous set of punching knives is cleaned by the cleaning component during the subsequent punching, so as to ensure the cleanliness of the punching knives and avoid the residual glue on the punching knives causing damage to the cut surface of the OCA optical glue during punching. At the same time, multiple sets of punching knives are used in a circular manner to ensure the continuous punching and the punching efficiency of the OCA optical glue.

[0013] 2. When the punching cutter is cleaned by a scraper, the scraper can be in close contact with the punching position of the punching cutter, thereby ensuring that the scraper can scrape off the residual glue adhering to the punching cutter, ensuring the cleaning effect of the punching cutter and avoiding the residual glue from affecting the subsequent punching.

[0014] 3. The residual glue cleaned on the punching knife can be collected through the collection box, and the residual glue on it can be dropped by pulling the support plate outward, thus realizing the collection of residual glue and subsequent rapid processing, avoiding the accumulation of residual glue and falling onto the OCA optical glue, ensuring the clean surface of the OCA optical glue during punching and cutting, and improving the quality of OCA optical glue punching and cutting.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0021] like Figure 1-Figure 3 As shown, an OCA punching machine with PE release film provided by the utility model includes a base plate 1, an H-shaped bracket 3 is arranged on the base plate 1, and a first telescopic member 2 for driving the bracket 3 to move up and down is fixedly installed on the base plate 1, two groups of pressing plates 4 are slidably installed on the bracket 3, a second telescopic member 5 is fixedly installed on the pressing plate 4, and the second telescopic member 5 drives the mounting frame 6 to move, a rotating shaft 7 is rotatably installed in the mounting frame 6, and a plurality of punching knives 9 are fixedly installed on the rotating shaft 7, the punching knives 9 are provided with four groups distributed in a circular array around the rotating shaft 7, a first rotating power member 8 for driving the rotating shaft 7 to rotate is fixedly installed on the mounting frame 6, and a cleaning component 17 for cleaning residual glue on the punching knife 9 is provided on the mounting frame 6.

[0022] In actual application of this embodiment, the OCA optical glue to be punched is placed on the bottom plate 1, the positions of the two groups of pressing plates 4 are adjusted, and then the distance between the punching knives 9 on both sides perpendicular to the bottom plate 1 is adjusted, so that the distance value between the two groups of punching knives 9 is the same as the length of the OCA optical glue after cutting. After the adjustment is completed, the position of the pressing plate 4 is fixed by fixing screws. At this time, the first telescopic member 2 drives the bracket 3 to move downward, and the bracket 3 drives the pressing plate 4 to move downward and press the OCA optical glue on the bottom plate 1. After the pressing is completed, the second telescopic member 5 drives the mounting frame 6 to move downward, and the mounting frame 6 drives the punching knife 9 to move downward and punch the pressed OCA optical glue. After the punching is completed, the first telescopic member 2 drives the bracket 3 to move downward, and the bracket 3 drives the pressing plate 4 to move downward and press the OCA optical glue on the bottom plate 1. The frame 3 is reset, and the second telescopic member 5 drives the mounting frame 6 to reset. At this time, the first rotating power member 8 drives the rotating shaft 7 to rotate 90 degrees, so that the punching knife 9 that has completed the punching is rotated to the position of the cleaning component 17. At the same time, another set of clean punching knives 9 will be rotated to a vertical state for the next punching. Repeat the above steps to continue the punching of OCA optical glue. At the same time as the subsequent punching, the residual glue adhering to the previous set of punching knives 9 is cleaned through the cleaning component 17, so as to ensure the cleanliness of the punching knife 9 and avoid the residual glue on the punching knife 9 causing damage to the cut surface of the OCA optical glue during punching. At the same time, multiple sets of punching knives 9 are recycled to ensure the continuous punching and the punching efficiency of the OCA optical glue.

[0023] In an example of the present embodiment, the first rotating power component 8 is a first motor, and of course it can also be other components such as a hydraulic motor that can output rotational power. The first motor drives multiple groups of punching knives 9 to rotate, thereby realizing the switching of the punching knives 9. The first telescopic component 2 and the second telescopic component 5 are respectively the first electric telescopic rod and the second electric telescopic rod, and of course it can also be other components such as a hydraulic cylinder that can actively change the length. The first electric telescopic rod and the second electric telescopic rod respectively drive the bracket 3 and the mounting frame 6 to move.

[0024] like Figure 1-Figure 3 As shown, an OCA punching machine with a PE release film is provided by the utility model, and the cleaning component 17 includes a collection box 10, which is slidably mounted on a mounting frame 6 through two sets of sliding rods 11, and the side of the collection box 10 close to the mounting frame 6 is an open structure, and a third telescopic member 12 is fixedly mounted on the mounting frame 6 to drive the collection box 10 to move.

[0025] Specifically, a support plate 13 for supporting the fallen residual adhesive is slidably installed at the bottom of the collection box 10 , and the support plate 13 passes through a side wall of the collection box 10 .

[0026] Specifically, a screw rod 14 is rotatably installed in the collection box 10 , and a second rotating power member 16 for driving the screw rod 14 to rotate is fixedly installed on the collection box 10 , and the screw rod 14 drives the scraper 15 to move.

[0027] Specifically, the cross-sectional shape of the scraper 15 matches the cross-sectional shape of the blade portion of the punching knife 9 .

[0028] When this embodiment is actually used, after punching, a group of punching knives 9 rotate to a horizontal state and point to the collection box 10. At this time, the third telescopic member 12 drives the collection box 10 close to the mounting frame 6 so that the punching knife 9 enters the collection box 10. When the blade of the punching knife 9 moves to a position where the cross section of the scraper 15 coincides, the collection box 10 stops moving. At this time, the second rotating power member 16 drives the screw rod 14 to rotate, and then the screw rod 14 drives the scraper 15 to move along the blade part of the punching knife 9. Since the blade of the punching knife 9 coincides with the cross section of the scraper 15, the scraper 15 can scrape off the residual glue adhering to the punching position of the punching knife 9, thereby realizing the cleaning of the residual glue on the punching position of the punching knife 9, ensuring the cleanliness of the punching position of the punching knife 9, and avoiding the residual glue on the punching knife 9 causing punching When cutting, the cut surface of the OCA optical glue is damaged, and the scraper 15 can be in close contact with the punching position of the punching knife 9, thereby ensuring that the scraper 15 can scrape off the residual glue adhering to the punching knife 9, ensuring the cleaning effect of the punching knife 9, and avoiding the residual glue from affecting the subsequent punching. After the scraping is completed, the third telescopic member 12 pushes the collection box 10 back to its original position. When the residual glue adhering to the scraper 15 increases, the residual glue will fall down into the collection box 10 and fall on the support plate 13. After long-term use, the support plate 13 can be pulled outward to make the residual glue on it fall off, thereby realizing the collection of residual glue and subsequent rapid processing, avoiding the residual glue from accumulating and falling down onto the OCA optical glue, ensuring the surface cleanness of the OCA optical glue during punching, and improving the quality of the OCA optical glue punching.

[0029] In an example of the present utility model, the second rotating power member 16 is a second motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The second motor drives the scraper 15 to move through the screw 14, thereby realizing the cleaning of the punching knife 9. The third telescopic member 12 is a third electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The third electric telescopic rod drives the collection box 10 to move.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
