[0059] Another technical problem to be solved by the present invention is to provide a thickness detection device for use in a detection method for a thermoplastic polyurethane film, comprising the following steps:

[0060] Installation test:

[0061] The thermoplastic polyurethane film 437 to be tested is clamped and installed on the clamping assembly 43. After installation, the rotating platform 42 is controlled to rotate so that the film 437 on the single clamping assembly 43 can stay at the position of the film thickness gauge 3 in turn and obtain thickness detection;

[0062] Classification processing:

[0063] After the film 437 is inspected, for the workpiece with unqualified thickness, after it is moved to the position of the lifting plate 45 in front of the rotating platform 42, the pressing rod 46 presses down to separate the supporting plate 436 from the horizontal plate 432, thereby releasing the clamping and fixing of the film 437. Similarly, for the film 437 with qualified thickness, after it is transferred to the corresponding position of another lifting plate 45, the clamping state of the film 437 is also released.

[0064] Auxiliary feeding:

[0065] After the clamping state of the film 437 is released, the push head 486 is prompted to move and the unclamped film 437 is pushed out by controlling the movement of the first slider 483, so as to properly achieve the purpose of rapid material unloading.

[0066] The model of the film thickness gauge 3 in the device is THK-01. Since it is an existing structure, its structure will not be further described here. In the actual operation process, the device is firstly connected to the power supply, and the thermoplastic polyurethane film to be tested is clamped on the clamping assembly 43. After the film piece 437 is clamped and placed, the first motor 495 works and drives the second gear 497 to rotate, the second gear 497 drives the first gear 496 to rotate, the first gear 496 drives the annular tube 494 to rotate, and the annular tube 494 drives the rotating platform 42 to rotate. During the rotation of the rotating platform 42, the film pieces 437 on the single clamping assembly 43 can be sequentially passed through the film thickness gauge 3 for detection;

[0067] During the detection process, the second electric push rod 492 pulls the U-shaped pressing plate 491, and the two ends of the bottom of the U-shaped pressing plate 491 move downward to touch the two connecting plates 434, and the connecting plates 434 drive the moving block 433 to move, and the moving block 433 drives the horizontal plate 432 to move, and the horizontal plate 432 drives the film part 437 to move. When the film part 437 moves to touch the thickness measuring station on the film thickness gauge 3, in order to be detected smoothly, the film part 437 after detection moves to When the lifting plate 45 in front of the rotating platform 42 is in position, if the thickness is unqualified, the first electric push rod 48 on one side of the lifting plate 45 pulls the auxiliary plate 47, and the auxiliary plate 47 drives the lifting plate 45 to move downward, and the lifting plate 45 drives the connected pressing rod 46 to move, and after the pressing rod 46 moves, it squeezes the limiting rod 438, so that the limiting rod 438 drives the supporting plate 436 to move downward, and at this time the supporting plate 436 and the cross plate 432 give up clamping the film 437;

[0068] The moving directions of the two pushing plates 485 are the corresponding positions of the two lifting plates 45. When the clamping of the film part 437 is released, the electromagnet 477 on the same axis of the pushing plate 485 corresponding to the lifting plate 45 is energized to attract the adjacent metal plate 476. The metal plate 476 drives the control block 474 to move. After the control block 474 moves to the top of the third slider 472 on one side, the second motor 482 works and drives the threaded rod 481 to rotate. The threaded rod 481 drives the carrying plate 499 to move downward. The carrying plate 499 drives the control block 474 to move. Then, the control block 474 presses the third slider 472 downward, causing the third slider 472 to move downward. The third slider 472 drives the inclined plate 473 to flip. After the inclined plate 473 flips, it pushes the connected second slider 488. The second slider 488 moves and pushes the first slider 483 on the same axis. The first slider 48 3 drives the push plate 485 to move, and the push plate 485 drives the push head 486 to move. At this time, the push head 486 can push out the film piece 437 that is released from the clamped state. Similarly, the film piece 437 with qualified thickness can be pushed out and unloaded after moving to the corresponding position of the same axis of another lifting plate 45, so as to achieve the purpose of classified delivery. After the unloading is completed, the two sides of the new film piece 437 are placed on the two supporting plates 436 respectively. Due to the elastic force of the first spring 439, the limit rod 438 drives to move up at this time, and the limit rod 438 drives the supporting plate 436 to move up, so that the supporting plate 436 cooperates with the cross plate 432 to tightly clamp the film piece 437, and the placement operation of the film piece 437 is completed. The process is simple and convenient. It only needs to manually take the film piece 437 and place it. There is no need for excessive human participation in the rest, which saves the expenditure of labor costs and is also conducive to improving the detection efficiency.

[0069] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
