[0002] Heat shrink film is a special plastic film that can shrink into a shape that fits the object tightly when heated, thus playing a role of packaging and protection. After the production of heat shrink film is completed, its thickness needs to be tested to ensure that its quality meets the requirements. There are many ways to measure the thickness of heat shrink film online, including capacitive thickness measurement, laser triangulation thickness measurement, laser interferometry thickness measurement, X-ray thickness measurement, infrared thickness measurement, etc.

[0023] like Figure 1-4As shown, a heat shrink film thickness detection device includes a workbench 1, and legs are provided around the bottom of the workbench 1 for support 19. The workbench 1 is provided with a first bearing device and a second bearing device. The first bearing device is used to place a heat shrink film 18, and the second bearing device is used to place a detector 6. Support legs 19 are provided around the bottom of the workbench 1, and inner cavities are provided on the inner sides of the bottoms of the support legs 19. The top of the inner cavity is connected to a telescopic motor 20, and the output end of the telescopic motor 20 is connected to a support plate 20, and the bottom of the support plate 21 is connected to a rubber pad 22. The support legs 19 are provided with a telescopic motor 20 and a support plate 20, and the output end of the telescopic motor 20 is connected to the support plate 20. The height of the support legs 19 can be raised or lowered by the telescopic motor 20, so as to adjust the level of the workbench 1 and ensure the horizontal state of the workbench 1. The horizontal setting of the workbench 1 can ensure that the detection equipment and the light source are level relative to the ground, which is conducive to the stability and reliability of the equipment, reduces the vibration and instability of the equipment, and improves the detection accuracy. A rubber pad 22 is connected to the bottom of the support plate 20 to further reduce the vibration of the device.

[0024] The first carrying device is slidably installed with a sliding platform 2, and the sliding platform 2 is connected to a Y-shaped frame. Clamp arms 4 are provided at both ends of the Y-shaped frame. Fixing devices are provided on the clamp arms 4. The fixing devices include spring clips, C-type clips, quick clips and other clamps, and can also be composed of adhesives such as suction cups or double-sided tapes. There are many similar items in the prior art, and this embodiment will not be repeated one by one. This embodiment takes ordinary double-sided tape as an example. When it is necessary to place heat shrink on the clamp arm 4, it is necessary to stretch the heat shrink film 18 first, and then move the two ends of the heat shrink film 18 to the clamp arms 4 on both sides respectively, and then fix the heat shrink film 18 with the double-sided tape. The fixation in this embodiment is only to prevent the heat shrink film 18 from curling during detection. Therefore, there is no need for a large fixing force, and most fixing devices on the market can meet the demand.

[0025] The second bearing device includes a U-shaped frame, and a detection port 5 is provided on the U-shaped frame, and a detector 6 is connected to one side of the detection port 5. In this embodiment, a spectroscopic detector 6 is selected, and its principle is that the heat shrink film 18 is usually made of polymer materials such as polyethylene, and these materials can be transparent or translucent. Therefore, light can penetrate the heat shrink film 18 to a certain extent. When light penetrates the heat shrink film 18, different penetration rates will be generated due to the different thicknesses of the heat shrink film 18. Therefore, by analyzing the signal through a spectrometer, the thickness of the heat shrink film 18 can be detected. In addition to the spectroscopic detector 6, non-contact sensing instruments such as laser scanners, ultrasonic measuring instruments, infrared detectors 6, etc. can all be used as detectors 6. The above instruments are all prior art, and their specific principles are no longer repeated in this embodiment.

[0026] The second bearing device of the present embodiment is provided with a mounting groove 12 below the detection port 5, and a detection hole 13 is provided above the mounting groove 12. The mounting groove 12 is used to install the spectrometer 6. Light passes through the heat shrink film 18 and is received by the spectrometer through the detection hole 13. The second bearing device is provided with a penetration groove 14 above the detection port 5. A penetration light source 15 is provided in the penetration groove 14. The penetration light source 15 is an optical fiber. The optical fiber is connected to a power supply device. The optical fiber emits an optical fiber that passes through the penetration groove 14 below and passes through the heat shrink film 18. The second bearing device is also provided with a filter 16 above the detection port 5. The filter 16 is located below the penetration light source 15. The filter 16 can limit the light in a specific wavelength range to pass through and be received by the spectrometer, which can increase the accuracy of the detection.

[0027] The first bearing device includes a bearing frame 7, and the two ends of the bearing frame 7 are provided with a driving pulley 8 and a driven pulley 9, and a conveyor belt 10 is provided between the driving pulley 8 and the driven pulley 9, and the conveyor belt 10 is connected to the sliding platform 2. The side of the first bearing device is provided with a driving device 11, and the output end of the driving device 11 is connected to the driving pulley 8. In this embodiment, after the heat shrink film 18 is fixed on the Y-shaped frame, the driving device 11, such as a driving motor, drives the conveyor belt 10 to rotate, and the conveyor belt 10 drives the Y-shaped frame and the heat shrink film 18 to move, so that the heat shrink film 18 moves to the detection port 5 for detection. The bearing frame 7 can drive the Y-shaped frame to move, so that it is convenient to quickly move to the detection location after fixing it, thereby accelerating the detection rate.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
