[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0021] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] Example 1:

[0023] Combination Figures 1-4 As shown, this embodiment provides a composite membrane production quality inspection device, including: a main body structure.

[0024] The main structure includes a base plate, guide rollers symmetrically mounted on the top of the base plate, side plates symmetrically fixed on both sides of the base plate, detection rollers rotatably mounted on the opposite side plates, brackets fixed on both sides of the side plates, electric telescopic rods symmetrically mounted on the brackets and extending through the brackets, a U-shaped frame fixed to the bottom of the electric telescopic rods, round rods fixed on the opposite inner surfaces of the U-shaped frame, and multiple detection plates arranged in an array and rotatably sleeved on the round rods.

[0025] The base plate is used to install other components, and the guide roller is used to guide the composite film onto the detection roller and ensure that the composite film can be tensioned on the detection roller, thereby ensuring the flatness of the composite film during detection.

[0026] The side plate is used to install the detection roller to ensure its stability. The detection roller is used to bypass the composite film, making it convenient for the detection plate to detect air bubbles on the composite film.

[0027] The bracket is used to install the electric telescopic rod. The bottom end of the electric telescopic rod is fixedly connected to the U-shaped frame, so that the electric telescopic rod can drive the U-shaped frame to move up and down, that is, adjust the distance between the detection plate and the detection roller, so as to adjust the detection accuracy. The smaller the distance between the two, the higher the detection accuracy, and vice versa.

[0028] In addition, a laser rangefinder is installed at the top of the support frame, which can accurately detect the movement distance of the U-shaped frame, ensuring the stability and accuracy of the U-shaped frame adjustment. Alarm lights are installed on both sides of the top of the support frame to alert workers when a bubble is detected.

[0029] Rectangular holes are made on both sides of the bracket, and the two sides of the U-shaped frame are fitted into the rectangular holes. Semicircular grooves are made on the opposite inner walls of the rectangular holes. Semicircular protrusions are symmetrically arranged at both ends of the U-shaped frame, and the semicircular protrusions are fitted into the semicircular grooves to ensure the stability of the U-shaped frame when it moves up and down.

[0030] The U-shaped frame is used to install the round rod, which is used to install the detection plate and facilitates the rotation of the detection plate. The detection plate is T-shaped, with an anode contact on one side and a cathode contact on the other side. The anode and cathode contacts between adjacent detection plates are in contact with each other to form a current path.

[0031] A cathode contact plate is installed on one inner side of a U-shaped frame, and an anode contact plate is installed on the other inner side. An array of detection plates is attached to the cathode contact plate on one side and to the anode contact plate on the other. A current input terminal is installed on one side of the U-shaped frame, and a current output terminal is installed on the other side. A current sensor is installed on the current output terminal. The current input terminal is electrically connected to the cathode contact plate via wires, and the current output terminal is electrically connected to the anode contact plate via wires. Through this arrangement, a current path is formed by the current input terminal, the cathode contact plate, multiple attached detection plates, the anode contact plate, and the current output terminal. When a bubble protrudes on the composite membrane, the bubble protrudes, as it passes the detection roller, cause the corresponding detection plate to rotate, disconnecting the anode and cathode contacts on the adjacent detection plates on both sides. At this time, the current path formed by the current input terminal, the cathode contact plate, multiple detection plates, the anode contact plate, and the current output terminal is broken. The current sensor detects the disappearance of the current output from the current output terminal, thus indicating the presence of a bubble protrudes on the composite membrane.

[0032] The working principle and usage process of this utility model are as follows: In use, the composite film is passed through one side guide roller, around the detection roller, and then fed out from the other side guide roller. As the composite film rotates on the detection roller, the detection plate monitors the bubble protrusions on the composite film in real time. When there is a bubble protrusion on the composite film, the bubble protrusion drives the corresponding detection plate to rotate to one side, causing the detection plate to disconnect from the anode and cathode contacts on the adjacent detection plates on both sides. At this time, the current path composed of the current input terminal, cathode contact plate, multiple detection plates, anode contact plate, and current output terminal is disconnected. The current sensor detects that the current output from the current output terminal has disappeared, which indicates that there is a bubble protrusion on the composite film and activates the alarm light to alert the workers.

[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
