The lower thread detection end of the thread detection machine 53 is rotated to match the thread 91 of the safety belt frame 90.

[0042] The transfer and distribution mechanism 70 includes a translation cylinder assembly 71, a second lifting cylinder 72, a transfer chassis 73, an adsorption plate 74, and a middle foot through-stop pressure attachment block 75. The translation cylinder assembly 71 is installed on the corresponding end surface of the beam 111 and is installed along the beam 111 to the side of the defective product box 60. The output block of the translation cylinder assembly 71 is fixedly equipped with a cylinder seat of the second lifting cylinder 72.

The safety belt frame 90 is separated from the separation end 122 and the carrier 80, and then falls into the rear workstation along the guide end 123.

[0045] In specific implementation, the support body of the circulating conveyor line 30 is fixedly mounted at the center position of the width direction of the upper plate 11 and arranged along the length direction of the upper plate 11. The rear end of the support body is provided with a driving wheel group 32, and the front end of the support body protruding from the upper plate 11 is provided with a driven wheel group 33. The input roller group 37 of the driving wheel group 32 is connected to the output roller group 36 output by the power motor 35 on the side through a belt 34, which ensures that the assembly of the circulating conveyor line 30 is convenient and quick.

[0046] The defective product box 60 is concavely disposed at a corresponding position of the upper plate 11 to ensure reliable transfer.

[0047] Its working principle is as follows: the corresponding safety belt frame is placed on the carrier located at the front end of the upper part of the conveyor loop through manual or mechanical transfer. Then the conveyor loop line drives the safety belt frame to pass the CCD lens photo detection, the two side foot detection mechanism detection, the screw thread detection mechanism detection, and the middle foot detection mechanism detection in sequence. After passing the inspection, it flows into the rear workstation. If the inspection fails, it is transferred to the defective product box through the transfer and material separation mechanism. The safety belt frame is inspected by the go-no-go gauge after the visual inspection, which ensures that the inspection is efficient and reliable to meet the inspection needs of large-scale production capacity.
