[0025] 1.

When the clamping piece holds the decorative panel and rotates 90 degrees, the first mounting frame rises to the highest point and detects both ends of the decorative panel through the first detection head. When it continues to rotate, the first mounting frame starts to descend, and then the first detection head detects one side of the decorative panel again. Whether it is consistent can be judged by the first detection heads set up above and below, thereby improving the accuracy of the detection.

[0029] 5. The first detection head will detect the reference detection plate. The reference detection plate is the detection reference plate. When the first detection head detects, a shadow appears, which means that dust is adhered to the outside of the first detection head. Therefore, the third liquid telescopic rod is started to shrink. The third liquid telescopic rod pulls the connecting shaft to rotate the rotating disk, and then the side of the rotating cylinder with the connecting groove rotates to the second dust suction position. At this time, the second dust suction is aimed at the first detection head and then the outside of the first detection head is vacuumed, thereby improving the accuracy of the detection of the first detection head.

Through the action of the second spring 603, the second mounting frame 602 can be located in the middle position to scan and detect both sides of the decorative panel. When one end of the decorative panel moves from the first transmission roller 401 to the second transmission roller 402, the two first detection heads 501 and the second detection heads 604 scan one end of the decorative panel and detect the other end as the decorative panel moves, thereby avoiding obstruction caused by clamping the decorative panel and improving the accuracy of detection.

[0054] like Figures 3 to 8 As shown, embodiment 2: the first transmission roller 401 passes through the moving plate 4 and is rotatably connected to the moving plate 4, a slide groove is opened inside the moving plate 4, a sliding block 403 is arranged inside the slide groove, the second transmission roller 402 passes through the sliding block 403 and is rotatably connected to the sliding block 403, a second hydraulic rod 405 is arranged inside the slide groove, both ends of the second hydraulic rod 405 are respectively fixedly connected to the sliding block 403 and the moving plate 4, and an auxiliary wheel 404 is rotatably connected to one side of the sliding block 403.

[0055] In specific implementation, due to the different sizes of decorative panels, the second hydraulic rod 405 inside the movable plate 4 can be started, and the second hydraulic rod 405 pushes the sliding block 403, thereby driving the second transmission roller 402 to move, thereby adjusting the distance between the first transmission roller 401 and the second transmission roller 402, and it can be used for decorative panels of different sizes, and an auxiliary wheel 404 is rotatably connected to one side of the sliding block 403.

[0057] The synchronous part also includes a driving motor 407 fixedly connected to the outer side of the movable plate 4, the output shaft of the driving motor 407 is fixedly connected to the first transmission roller 401, and transmission pulleys 4062 are arranged on the outer sides of the tensioning block 4061, the first transmission roller 401 and the second transmission roller 402, and the transmission pulley 4062 is rotationally connected to the tensioning block 4061, the first transmission roller 401 and the second transmission roller 402 are fixedly connected to the transmission pulley 4062 on one side, and belts are sleeved on the outer sides of the three transmission pulleys 4062 and are connected through belt transmission.

[0058] In specific implementation, when one end of the decorative plate moves to the first transmission roller 401, the driving motor 407 is started, and the driving motor 407 drives the first transmission roller 401 to rotate, thereby pushing the decorative plate to move forward, and through the belt transmission between the tensioning block 4061 and the first transmission roller 401 and the transmission pulley 4062 on the outside of the second transmission roller 402, the second transmission roller 402 also maintains transmission. When the detection is completed, the second hydraulic rod 405 is started to move the second transmission roller 402 clamping the decorative plate together, so that the decorative plate is close to another conveying device 9. Since the tensioning block 4061 and the fixed frame 406 are fixedly connected by the first spring 4064 and the first telescopic rod 4063, the belt transmission can be adjusted to keep the second transmission roller 402 in a conveying state.

The driven gear 702 is meshed with the driving gear 703.

[0061] In specific implementation, when the flip motor 3 drives the group clamping part to rotate, the bevel gear plate 504 fixedly connected to the outside of the rotating shaft 301 rotates together, and the bevel gear plate 504 drives the meshing bevel gear 505 to rotate, and the bevel gear 505 drives the transmission rod 506 to rotate. The belt transmission between the transmission rod 506 and the reciprocating screw rod 503 causes the reciprocating screw rod 503 to rotate, and then the reciprocating screw rod 503 drives the first mounting frame 502 to rise and fall. When the clamping part holds the decorative panel and rotates 90 degrees, the first mounting frame 502 rises to the highest point and detects both ends of the decorative panel through the first detection head 501. When it continues to rotate, the first mounting frame 502 begins to descend, and then the first detection head 501 detects one side of the decorative panel again. Whether it is consistent can be determined by the first detection heads 501 set up above and below, thereby improving the accuracy of the detection.

[0062] like Figures 9 to 11As shown in the fourth embodiment, the dust collection assembly includes a first dust collection frame 801 attached to the outside of the cleaning roller 701, the top of the first dust collection frame 801 is rotatably connected to a rotating cylinder 802, a connecting groove 8021 is provided on the outside of the rotating cylinder 802, the rotating cylinder 802 is connected to the first dust collection frame 801 through the connecting groove 8021, the rotating cylinder 802 is rotatably connected to the second dust collection frame 803, one end of the rotating cylinder 802 is fixedly connected to a connecting rod 806, the connecting rod 806 passes through the movable plate 4 and is rotatably connected to the movable plate 4, and one end of the connecting rod 806 A rotating disk 8022 is fixedly connected, a connecting shaft 8023 is fixedly connected to one side of the rotating disk 8022, a third liquid telescopic rod 8024 is hinged between the connecting shaft 8023 and the movable plate 4, the other end of the rotating cylinder 802 is fixedly connected to a dust collection device 805 for dust collection, the dust collection device 805 is fixedly connected to the outside of another movable plate 4, a control detection plate 804 is fixedly connected between the two relatively movable plates 4, a support rod is fixedly connected to the outside of the first dust collection frame 801 and the second dust collection frame 803, and the support rod is fixedly connected to the movable plate 4.

[0063] In specific implementation, when the decorative plate contacts the first transmission roller 401, the first transmission roller 401 rotates to drive the driving gear 703 to rotate, the driving gear 703 drives the meshing driven gear 702 to rotate, and the driven gear 702 drives the fixedly connected cleaning roller 701 to rotate, and then the cleaning roller 701 cleans the dust on the surface of the decorative plate to prevent the dust from affecting the judgment of the first detection head 501. In order to improve the cleaning effect of the cleaning roller 701, a large number of cleaning hairs can be set on the outside of the cleaning roller 701;

[0064] After the cleaning roller 701 cleans the dust, a large amount of dust adheres to the surface of the cleaning roller 701. A first dust suction frame 801 is provided on the cleaning roller 701.

The reference detection plate 804 is a detection reference plate. When the first detection head 501 detects, a shadow appears, which indicates that dust is adhered to the outside of the first detection head 501. Therefore, by starting the third liquid telescopic rod 8024 to retract, the third liquid telescopic rod 8024 pulls the connecting shaft 8023 to rotate the rotating disk 8022, and then the side of the rotating cylinder 802 with the connecting groove 8021 is rotated to the position of the second dust suction 803. At this time, the second dust suction 803 is aimed at the first detection head 501 and then performs dust suction on the outside of the first detection head 501, thereby improving the detection accuracy of the first detection head 501.

[0066] A method for detecting defects in vehicle door interior trim is also provided, comprising the following steps;

[0067] Step 1: Place the door interior panel on the conveying device 9 for transmission. When the door interior panel is transported between the two support frames 1, the first detection heads 501 arranged above and below scan and detect one end of the interior panel.
