Description

A high-sensitivity thickness measuring instrument for release film processing Technical Field

[0001] This utility model relates to the field of release film testing technology, and in particular to a high-sensitivity thickness measuring instrument for release film processing. Background Technology

[0002] Release film refers to a film whose surface can be distinguished. When a release film comes into contact with a specific material under limited conditions, it is not sticky or has only slight stickiness.

[0003] However, in existing technologies, in order to detect the quality and specifications of release film after production, it is often necessary to measure the thickness or width of the release film to determine whether it is qualified. However, when using a thickness gauge to detect the thickness of the release film, if the release film is bent or warped, it will affect the incident angle of the laser beam, resulting in measurement errors. At the same time, after being left for a long time, dust can easily accumulate on the laser head of some thickness gauges, which can also affect the measurement results. Therefore, a solution is needed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art: when using a thickness measuring instrument to measure the thickness of release film, if the release film is bent or warped, it will affect the incident angle of the laser beam, resulting in measurement errors. At the same time, after being left unused for a long time, dust easily accumulates on the laser head of some thickness measuring instruments, which can also affect the measurement results.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-sensitivity thickness detector for release film processing, comprising: a support frame; two sets of guide rollers fixedly disposed on the inner wall of the support frame at symmetrical locations; and further comprising:

[0006] An electric push rod is fixedly installed on the inner wall of the support frame. The output end of the electric push rod is provided with a movable frame, and an ejector roller is fixedly installed on the inner wall of the movable frame at a symmetrical location.

[0007] Two telescopic rods are fixedly installed symmetrically on one side surface of the movable frame, and one end of the two telescopic rods is fixedly installed on the inner wall of the support frame.

[0008] A hydraulic cylinder is fixedly mounted on the outer surface of the support frame. The output end of the hydraulic cylinder is provided with a U-shaped frame, and one end of the U-shaped frame is movably embedded inside the support frame.

[0009] Preferably, a mounting bracket is fixedly provided on one end surface of the U-shaped frame, and positioning rollers are provided on the inner wall of the mounting bracket at symmetrical locations.

[0010] The technical effect of adopting the above-mentioned further solution is that when the U-shaped frame moves, the mounting bracket on the surface drives the positioning roller to move down, which works in conjunction with the guide roller to position the release film.

[0011] Preferably, a limiting groove is formed on the inner wall of the mounting bracket near the center, and a slider is slidably embedded inside the limiting groove.

[0012] The technical advantage of adopting the above-mentioned further solution is that the limiting groove opened inside the mounting bracket provides a limiting function for the slider while facilitating position adjustment.

[0013] Preferably, a limiting cylinder is provided on the surface of the slider, and a spring is fixedly provided inside the limiting cylinder.

[0014] The technical effect of adopting the above-mentioned further solution is that the limiting cylinder on the surface of the slider provides fixed support for the spring.

[0015] Preferably, a movable sleeve is fixedly provided on one end surface of the spring, and the movable sleeve is slidably embedded inside the limiting cylinder.

[0016] The technical effect of adopting the above-mentioned further solution is that the spring is connected to the surface of the movable sleeve, so that it can slide within the limiting cylinder.

[0017] Preferably, the movable sleeve is provided with an anti-slip washer inside, and the anti-slip washer is movably connected to the surface of the laser measuring head.

[0018] The technical effect of adopting the above-mentioned further solution is that by moving the anti-slip gasket inside the sleeve to contact the laser measuring head, it provides protection when not in use and prevents dust accumulation.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. In this utility model, the release film is placed along two guide rollers, the hydraulic cylinder is started, and the U-shaped frame moves the mounting frame downward, so that the positioning roller on the surface contacts the surface of the release film. With the support force provided by the guide roller, the release film is positioned. Then the electric push rod is started, so that the moving frame moves upward along the telescopic rod, so that the ejector roller contacts the release film and stretches and tightens it, thereby making its surface flat and preventing wrinkles from appearing on the surface later, which would affect the measurement accuracy.

[0021] 2. In this utility model, by pressing the movable sleeve on the surface of the spring, it moves along the inside of the limiting cylinder and away from the surface of the laser measuring head. Then, the slider moves along the inside of the limiting groove, causing the slider to leave the measurement path of the laser measuring head. This starts the thickness measuring instrument body and uses the laser measuring head to measure the release film. When not in use, by repeatedly pressing the movable sleeve, the movable sleeve is placed on the surface of the laser measuring head, and the anti-slip gasket contacts the laser measuring head to seal it, preventing dust from accumulating on the surface for a long time and affecting the measurement results.

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Example 1, as shown in Figures 1-4, provides a high-sensitivity thickness detector for release film processing, comprising: a support frame 1; two sets of guide rollers 101, fixedly mounted on the inner wall of the support frame 1 at symmetrical locations; further comprising: an electric push rod 102, fixedly mounted on the inner wall of the support frame 1, with a movable frame 1021 at the output end of the electric push rod 102, and an ejector roller 1023 fixedly mounted on the inner wall of the movable frame 1021 at symmetrical locations; two telescopic rods 1022, fixedly mounted at symmetrical locations on one side surface of the movable frame 1021, with one end of the two telescopic rods 1022 fixedly mounted on the inner wall of the support frame 1; and a hydraulic cylinder 103, fixedly mounted on the outer surface of the support frame 1, with a U-shaped frame 1031 at the output end of the hydraulic cylinder 103, one end of the U-shaped frame 1031 being movably embedded inside the support frame 1.

[0032] In this embodiment, the release film is placed along the two guide rollers 101, and the hydraulic cylinder 103 is activated, causing the U-shaped frame 1031 to move the mounting frame 1032 downward. The positioning roller 1033 on the surface contacts the surface of the release film, and the release film is positioned with the support provided by the guide rollers 101. Then, the electric push rod 102 is activated, causing the moving frame 1021 to move upward along the telescopic rod 1022, so that the ejector roller 1023 contacts the release film and stretches and tightens it, thereby making its surface flat and preventing wrinkles from appearing on the surface later, which would affect the measurement accuracy.

[0033] In Example 2, a mounting bracket 1032 is fixedly mounted on one end surface of the U-shaped frame 1031. Positioning rollers 1033 are provided on the inner wall of the mounting bracket 1032 at symmetrical locations. A limiting groove 1034 is formed on the inner wall of the mounting bracket 1032 near the center. A slider 1035 is slidably embedded inside the limiting groove 1034. A limiting cylinder 1036 is provided on the surface of the slider 1035. A spring 1038 is fixedly mounted inside the limiting cylinder 1036. A movable sleeve 1037 is fixedly mounted on one end surface of the spring 1038. The movable sleeve 1037 is slidably embedded inside the limiting cylinder 1036. An anti-slip washer 1039 is provided inside the movable sleeve 1037. The anti-slip washer 1039 is movably connected to the surface of the laser measuring head 201.

[0034] In this embodiment, by pressing the movable sleeve 1037 on the surface of the spring 1038, it moves along the inside of the limiting sleeve 1036 and away from the surface of the laser measuring head 201. Then, the slider 1035 moves along the inside of the limiting groove 1034, causing the slider 1035 to leave the measurement path of the laser measuring head 201. This starts the operation of the thickness measuring instrument body 2, which uses the laser measuring head 201 to measure the release film. When not in use, the movable sleeve 1037 is pressed again, causing it to be fitted onto the surface of the laser measuring head 201. The anti-slip washer 1039 contacts the laser measuring head 201 to seal it, preventing dust from accumulating on the surface and affecting the measurement results after prolonged placement.

[0035] Working principle: In use, the release film is placed along the two guide rollers 101. The hydraulic cylinder 103 is activated, causing the U-shaped frame 1031 to move the mounting frame 1032 downwards. This allows the positioning roller 1033 on the surface to contact the release film. With the support provided by the guide rollers 101, the release film is positioned. Then, the electric push rod 102 is activated, causing the moving frame 1021 to move upwards along the telescopic rod 1022, allowing the ejector roller 1023 to contact the release film and stretch it, thus smoothing its surface and preventing wrinkles from affecting measurement accuracy later. Additionally, during measurement, the surface of the spring 1038 is pressed... The movable sleeve 1037 is moved along the inside of the limiting sleeve 1036 and away from the surface of the laser measuring head 201. Then, the slider 1035 is moved along the inside of the limiting groove 1034, so that the slider 1035 is removed from the measurement path of the laser measuring head 201. The thickness measuring instrument body 2 is started to work, and the release film is measured with the help of the laser measuring head 201. When not in use, the movable sleeve 1037 is pressed again to make the movable sleeve 1037 fit on the surface of the laser measuring head 201. The anti-slip gasket 1039 contacts the laser measuring head 201 to seal it and prevent dust from accumulating on the surface for a long time, which would affect the measurement results.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
