Description

Technical Field

[0001] This utility model relates to release film production and testing equipment, specifically a device for synchronously detecting the coating amount of double-sided release film. Background Technology

[0002] In existing release film production, the coating amount and quality inspection can be completed in one thickness measurement for single-sided coated release films. However, for double-sided coated release films, the coating amount on both sides needs to be inspected. The second side is inspected after the first side is inspected. At this time, due to the influence of temperature, humidity and accuracy deviation of the two inspections, the inspection accuracy of the coating amount and thickness of the two sides is prone to large deviations. This has a significant impact on the adjustment and control of the coating amount of subsequent coating equipment, which is not conducive to the precise control of the coating amount of double-sided release films and the final control of the dry adhesive forming thickness. Summary of the Invention

[0003] This invention provides a simple structure for synchronous detection of double-sided release film coating amount, which can effectively ensure the accuracy of synchronous detection on both sides.

[0004] The technical solution adopted by this utility model is: a synchronous detection device for double-sided release film coating amount, characterized in that: it includes a test chamber, with an inlet at the top and an outlet at the bottom; left and right test frames are set on both sides of the test chamber in the direction of the inlet and outlet; two or more sets of horizontally arranged test drive rails are set on each of the left and right test frames; the test drive rails on the left and right test frames are opposite each other; an infrared thickness probe is set on the test drive rails; upper and lower dehumidification chambers are set on the upper and lower parts of the test chamber, respectively; desiccant is placed in the upper and lower dehumidification chambers; a dehumidification inlet is set on the upper part of the upper dehumidification chamber vertically corresponding to the inlet; a dehumidification outlet is set on the lower part of the lower dehumidification chamber vertically corresponding to the outlet; a constant temperature jacket is set on the outer periphery of the test chamber; and the constant temperature jacket is connected to a constant temperature water tank.

[0005] The dehumidifier box has drawer openings on both the left and right sides, and drawers with built-in desiccants are inserted into the drawer openings.

[0006] The constant temperature water tank is equipped with a heater and a temperature sensor.

[0007] The two horizontally opposite test drive rails on the left and right test frames drive the infrared thickness probe to feed in the same direction or in opposite directions.

[0008] The beneficial effects of this invention are as follows: The use of vertical inlet and outlet ports prevents the release film from being affected by the downward sinking of the horizontal support during vertical feeding, thus improving testing accuracy. The left and right test frames utilize horizontally driven test drive rails. Two opposing infrared thickness probes move horizontally, completing double-sided thickness measurement in one operation, resulting in high testing accuracy. Thickness measurement can be performed at the same horizontal position without downward conveying, and can also be performed within a fixed distance while continuously conveying downwards. Combined with the relative movement of the two infrared thickness probes, thickness measurement can be performed within an overlapping range. Thickness measurement is also performed on the coating amount within the length range of the glue applied by the coating roller in a single rotation from the glue tank, improving testing accuracy while simultaneously allowing for coating amount control during coating production, thus comprehensively improving detection accuracy. The use of upper and lower dehumidification chambers controls the humidity of the testing environment, while the constant temperature jacket controls the temperature, preventing the testing environment from affecting testing accuracy and further ensuring detection precision.
