[0002] Copper clad laminate is a basic material widely used in the manufacture of electronic circuits. It is usually composed of an insulating substrate (such as epoxy resin, polyester, etc.) and one or more layers of copper foil. Its main function is to provide a conductive path for the circuit and serve as a supporting structure for the circuit. The advantages of copper clad laminate include good electrical properties, high mechanical strength and excellent thermal stability. It is widely used in mobile phones, computers, home appliances, automotive electronics and other fields.

[0003] In the production of copper clad laminates, they need to be cut and then packaged after testing. The testing includes the thickness test of the copper clad laminates. The existing thickness test of copper clad laminates mostly uses laser equipment to measure the thickness of the copper clad laminates.

[0004] However, during the actual testing process, since the testing equipment cannot effectively fix and level the copper clad laminate, the uneven or warped copper clad laminate after cutting will affect the accuracy of the test, thereby causing measurement errors. Therefore, improvements are needed to address the above problems. Utility Model Content

[0020] A rotating shaft 8 is rotatably installed between the ends of the opposite sides of the two side plates 2, and a conveying roller 9 is fixedly installed on the surface of the two rotating shafts 8. The conveyor belt 3 is installed between the two conveying rollers 9, and a motor 10 fixedly connected to one end of one of the rotating shafts 8 is installed on one side of one of the side plates 2. A supporting plate 11 is fixedly installed between the opposite sides of the two side plates 2, and the top of the supporting plate 11 is connected to the lower part of the upward section of the conveyor belt 3, and the supporting plate 11 is located below the laser rangefinder 5, so that the copper clad laminate can be effectively transported and tested and supported. An electric telescopic cylinder 12 is installed on the top of the inner side of the inverted L-shaped fixed plate 4, and the long pressure block 6 is fixedly installed on the telescopic end of the electric telescopic cylinder 12, so that it can effectively perform lifting and adjustment and fix the copper clad laminate.

[0021] During detection, the conveyor belt 3 is driven to rotate by starting the motor 10 and through the two rotatable rotating shafts 8 and the conveying rollers 9 thereon, and then the copper clad laminate to be detected is placed on the surface of the conveyor belt 3 at equal distances. When the conveyor belt 3 transports the copper clad laminate to between the laser rangefinder 5 and the bottom of the long pressing block 6, the conveying is stopped, and then the electric telescopic cylinder 12 is started to extend and drive the long pressing block 6 and the roller 7 to move downward, so that the long pressing block 6 and the roller 7 cooperate with the support plate 11 to abut and fix one end of the copper clad laminate. Then, the copper clad laminate is leveled by the rolling of the roller 7. After the copper clad laminate is leveled, the thickness is measured by the laser rangefinder 5.

The rotation of the threaded rod 17 will cause the fixed adjustment plate 16 to move on the surface and drive the two adjustment rods 14 to move. The movement of the two adjustment rods 14 will drive the fixed shaft 15 and the roller 7 to move. The movement of the roller 7 will roll on the surface of the copper clad laminate and level the copper clad laminate, which is beneficial to improve the accuracy of the thickness detection of the copper clad laminate.
