Description

Technical field

[0001] The utility model relates to the technical field of tape detection, in particular to an air suction thickness detection device. Background technique

[0002] In the process of tape processing, according to the process requirements, it is necessary to detect the thickness of the tape. Before the thickness detection, it is necessary to guide and position the tape to avoid the situation that the tape thickness detection position does not match the thickness information due to the deviation of the tape. At the same time, the unstable conveying speed of the tape, the uneven mass distribution of the tape, and the change of the tension of the tape will all cause the tape to shake, and wrinkles are easy to generate at the edge of the tape. The thickness detection laser displacement sensor will emit a laser beam to the tape and calculate the time difference of the laser beam reflected back by the tape to calculate the thickness of the object. The shaking and wrinkling of the tape will affect the reflection time of the laser beam, resulting in deviation in the tape thickness detection and inability to accurately measure the tape thickness. Therefore, it is necessary to position the tape during thickness detection.

[0003] Therefore, an air suction thickness detection device for solving the above problems is needed. Summary of the utility model

[0004] The utility model provides an air suction thickness detection device, which guides, flattens and positions the tape through a tape edge de-wrinkling frame and a detection platform, avoiding the deviation and shaking of the tape during thickness measurement, thereby improving the accuracy of tape thickness detection.

[0005] The technical solution of the utility model is realized as follows:

[0006] The air suction thickness detection device includes a thickness detection platform. A plurality of tape leveling matrix holes for adsorbing the tape are arranged on the top of the thickness detection platform. An air suction cavity is arranged on the detection platform, and each tape leveling matrix hole is communicated with the air suction cavity. A plurality of laser displacement sensors for detecting the thickness of the tape are fixedly installed on the thickness detection platform, and each laser displacement sensor is arranged above the thickness detection platform. Along the advancing direction of the tape, a tape edge de-wrinkling frame for guiding and flattening the tape is arranged upstream of the thickness detection platform;

[0007] The tape edge dewrinkling frame includes two side plates hinged to the thickness detection platform. Fasteners for locking the corresponding side plates are respectively arranged between the thickness detection platform and the two side plates. A number of dewrinkling rollers are rotatably installed between the two side plates. Two tape edge dewrinkling vertical plates are slidably installed between the two side plates. Each dewrinkling roller passes through the two tape edge dewrinkling vertical plates. A dewrinkling support is respectively and fixedly installed on the two side plates. A dewrinkling elastic sheet mounting rod is jointly installed on the two dewrinkling supports. An elastic clamping plate for clamping the dewrinkling elastic sheet mounting rod is arranged on each dewrinkling support. Two tape edge dewrinkling elastic sheets for leveling the tape in cooperation with one of the dewrinkling rollers are fixedly installed on the dewrinkling elastic sheet mounting rod. During use, the outer side walls of the two tape edge dewrinkling elastic sheets are both abutted against the inner side walls of the adjacent tape edge dewrinkling vertical plates.

[0008] As a preferred technical solution, a middle tape adsorption area is arranged at the top of the thickness detection platform. A tape edge adsorption area is arranged on each side of the middle tape adsorption area. The tape leveling matrix holes include middle tape leveling matrix holes arranged in the middle tape adsorption area and edge tape leveling matrix holes arranged in the tape edge adsorption area. The number of the edge tape leveling matrix holes on each tape edge adsorption area is less than the number of the middle tape leveling matrix holes on the middle tape adsorption area.

[0009] As a preferred technical solution, at least a pair of mounting frames are fixedly installed on the thickness detection platform. A mounting rod is jointly installed on the two mounting frames. A number of mounting blocks are constrained and installed on the mounting rod. A laser displacement sensor is fixedly installed on each mounting block.

[0010] As a preferred technical solution, a number of dewrinkling vertical plate guide rods are fixedly installed between the two side plates. The two tape edge dewrinkling vertical plates are jointly slidably installed on the dewrinkling vertical plate guide rods. Locking bolts for locking are arranged between the two tape edge dewrinkling vertical plates and one of the dewrinkling vertical plate guide rods.

[0011] As a preferred technical solution, the air suction cavity is connected with an air pump. The air suction cavity is communicated with a pressure relief pipe. A pressure relief valve is arranged on the pressure relief pipe.

[0012] By adopting the above technical solutions, the beneficial effects of the utility model are as follows:

[0013] Since the air suction thickness detection device includes a detection platform, during the use of this device, the material tape continuously advances under the traction of the traction mechanism. First, the material tape is guided by the material tape edge dewrinkling frame, avoiding the deviation of the material tape during thickness measurement and improving the accuracy of the material tape thickness detection. When the material tape passes through between the dewrinkling roller and the material tape edge dewrinkling elastic sheet, the material tape edge dewrinkling elastic sheet flattens the wrinkles on both sides of the material tape, ensuring the flatness during the material tape thickness detection. When the material tape moves to the detection platform, a negative pressure is formed at the position of the material tape flattening matrix holes, causing the bottom of the material tape to adhere to the top of the air suction detection platform, realizing the positioning of the material tape on the detection platform, thereby avoiding the jitter of the material tape during thickness measurement and further improving the accuracy of the material tape thickness detection. At the same time, the laser displacement sensor emits a laser beam towards the material tape and calculates the time difference of the laser beam reflected back by the material tape to calculate the thickness of the object, greatly reducing the error of the material tape thickness detection and accurately measuring the thickness of the material tape.

[0014] Since the air suction thickness detection device includes the middle material tape flattening matrix holes and the edge material tape flattening matrix holes, the material tape is subjected to zoned air suction through the settings of the middle material tape flattening matrix holes and the edge material tape flattening matrix holes. Since the edges and the middle positions of the material tape are more prone to wrinkling, by increasing the number of the edge material tape flattening matrix holes, the suction force of the thickness detection platform on the edge of the material tape is increased, so that the more easily wrinkled edge is flattened on the thickness detection platform, further ensuring the accuracy of the thickness detection.

[0015] Since the dewrinkling elastic sheet mounting rod is mounted on the material tape edge dewrinkling frame through two elastic clamping plates, during the use of this device, the elastic clamping plates themselves have elasticity and can automatically clamp the dewrinkling elastic sheet mounting rod, thus realizing the rapid adjustment of the dewrinkling elastic sheet mounting rod. By rotating the dewrinkling elastic sheet mounting rod, the force of the material tape edge dewrinkling elastic sheet pressing on the material tape can be realized, so as to be applicable to the flattening of material tapes with different wrinkling situations.

[0016] The laser displacement sensor is constrained and mounted on the mounting rod. By adjusting the position of the mounting block on the mounting rod, the thickness detection of different positions on the material tape by the laser displacement sensor can be realized. By analyzing the thickness information measured by the laser displacement sensor at different positions, the comprehensive thickness information of the material tape can be obtained, improving the accuracy of the material tape thickness detection.
