[0002] Automobile curtain airbag brackets are a type of automotive accessory. During their processing, to ensure quality, the hole spacing required for them needs to be inspected. A search revealed that a typical prior art hole spacing detection device, such as publication number CN101907434A, is a side-hole spacing detection device used to detect whether the distance between the center of a through-hole on a workpiece and the edge of the plate meets specifications. The device includes a positioning member, a support member, and a measuring member, each of which is disposed on the support member. The positioning member can be abutted against the edge of the workpiece. The distance between the side of the positioning member abutting the edge of the plate and the center of the measuring member is equal to the standard value of the distance between the edge of the workpiece and the center of the through-hole. When the distance between the center of the through-hole on the workpiece and the edge of the plate meets specifications, the measuring member can be inserted into the through-hole. When the distance between the center of the through-hole on the workpiece and the edge of the plate does not meet specifications, the measuring member cannot be inserted into the through-hole. Its main feature is that it can quickly and accurately detect the side-hole spacing of a workpiece.

[0003] In summary, the existing hole spacing detection device requires manual removal of workpieces after detecting defective products.

[0004] The degree of automation is low and the operation is not convenient enough. In view of the above problems, the existing equipment needs to be improved. Utility Model Content

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a device for detecting the hole distance of an automobile air curtain bracket, comprising a frame, a PPU grabbing module and a three-camera detection station,

[0007] An automatic rejection mechanism is installed on the frame, and the automatic rejection mechanism includes a conveyor, a discharge port, a carrying plate, an electric telescopic rod and a push block. The discharge port is provided on one side wall of the conveyor, and a carrying plate is provided on the other side wall of the conveyor. The electric telescopic rod is installed on the carrying plate, and one end of the electric telescopic rod is connected to the push block.

[0008] Preferably, the pushing block is arranged opposite to the feeding opening, and the size of the pushing block is smaller than the size of the feeding opening.

[0012] Preferably, the three-camera inspection station is electrically connected to the conveyor, and the three-camera inspection station is arranged outside the manual loading station.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the automobile air curtain bracket hole distance detection device,

[0014] (1) The utility model can effectively solve the problem that the existing hole spacing detection device needs to manually reject the workpiece after detecting defective products, has a low degree of automation, and is not convenient to operate through the coordinated use of the automatic rejection mechanism and the three-camera detection station. After the three-camera detection station detects defective products, it will transmit the information to the electric telescopic rod in the automatic rejection mechanism. When the electric telescopic rod moves to the front side of the push block, it pushes the push block to push the workpiece on the conveyor into the discharge port for automatic rejection, while the qualified products are automatically discharged under the conveyor, thereby improving the automation level and detection efficiency of the device;

[0015] (2) The utility model can effectively solve the problem of blind spots in existing detection devices by using a PPU gripping module in conjunction with a three-camera detection station. The three-camera detection station detects the hole spacing of the air curtain bracket on the manual loading station from the left, right and top. At the same time, the PPU gripping module drives the manual loading station to move through the moving plate when it moves, so that the three-camera detection station can move and adjust its detection position, thereby improving the comprehensiveness of the detection, avoiding blind spots in the detection, and ensuring the quality of the detection.
