[0002] like Figure 1 and Figure 2 As shown, the automotive carbon canister A has three blind holes and three connection ports. The three blind holes are the first blind hole A1, the second blind hole A2 and the third blind hole A3; the three connection ports are the first connection port B1, the second connection port B2 and the third connection port B3.

[0003] Currently, the automotive carbon canister A is not subjected to end-of-life testing before leaving the factory. After being installed in vehicles, leaks and the absence of springs inside the blind holes have been discovered, leading to a large-scale recall of vehicles and huge economic losses. Utility Model Content

[0004] The purpose of this invention is to solve the problem that automotive carbon canisters lack end-of-line testing before leaving the factory, resulting in leaks after assembly into vehicles and the absence of springs inside blind holes, leading to large-scale vehicle recalls and huge economic losses. The invention provides an end-of-line testing device for automotive carbon canisters.

[0006] The carbon canister spring detector includes a first carbon canister spring detector, a second carbon canister spring detector, and a third carbon canister spring detector; the positions of the first carbon canister spring detector, the second carbon canister spring detector, and the third carbon canister spring detector correspond to the first blind hole, the second blind hole, and the third blind hole of the automobile carbon canister, respectively.

[0007] The carbon canister airtightness and ventilation capability detector includes a first carbon canister airtightness and ventilation capability detector, a second carbon canister airtightness and ventilation capability detector, and a third carbon canister airtightness and ventilation capability detector; the positions of the first carbon canister airtightness and ventilation capability detector, the second carbon canister airtightness and ventilation capability detector, and the third carbon canister airtightness and ventilation capability detector correspond to the first connection port, the second connection port, and the third connection port of the automobile carbon canister, respectively.

[0008] The carbon canister spring detector is located on the left side of the carbon canister fixing fixture. The carbon canister spring detector is installed on the first fixing plate. The first fixing plate is fixedly connected to the connecting block. The first cylinder is fixed on the platform. The head end of the first telescopic rod of the first cylinder is fixedly connected to the connecting block. A guide rail is provided on the top surface of the first cylinder. A guide plate is provided in the guide rail. The head end of the guide plate is fixed to the connecting block. The guide plate can move synchronously with the first telescopic rod of the first cylinder.

[0009] The first carbon canister airtightness and ventilation capacity detector is fixed to the second telescopic rod of the second cylinder by the second fixing plate, and the second cylinder is fixed on the platform.

[0011] The third carbon canister airtightness and ventilation capacity detector is fixed to the fourth telescopic rod of the fourth cylinder by the fourth fixing plate, and the fourth cylinder is fixed to the platform.

[0012] The working process of this utility model:

[0013] The car carbon canister is placed on the carbon canister fixing fixture and fixed. The first cylinder is started, and the first extension rod of the first cylinder moves the carbon canister spring detector inward. The first carbon canister spring detector, the second carbon canister spring detector, and the third carbon canister spring detector enter and abut against the first blind hole, the second blind hole, and the third blind hole of the car carbon canister, respectively. The first carbon canister spring detector, the second carbon canister spring detector, and the third carbon canister spring detector detect whether a spring is installed in the first blind hole, the second blind hole, and the third blind hole of the car carbon canister, respectively.

[0014] Then, the second, third, and fourth cylinders are activated. The second, third, and fourth cylinders respectively drive the first, second, and third carbon canister airtightness and ventilation capacity detectors to move inward. The first, second, and third carbon canister airtightness and ventilation capacity detectors are connected to the first, second, and third connection ports of the automotive carbon canister respectively, and compressed air is injected into the automotive carbon canister to detect the ventilation capacity and airtightness of the automotive carbon canister.

[0015] When all the tests conducted by the carbon canister spring detector and the carbon canister airtightness and ventilation capacity detector are passed, the product is deemed qualified, and a marking device marks the qualified product on the carbon canister. If any one of the indicators is found to be unqualified, the carbon canister is deemed an unqualified product.

[0016] The beneficial effects of this utility model are:

[0017] Using this invention to perform terminal testing on automotive carbon canisters before they leave the factory ensures that defective products will not be installed in vehicles, thus avoiding large-scale vehicle recalls, preventing huge economic losses, and improving economic efficiency.
