Description

Technical Field

[0001] The utility model belongs to the technical field of automobile central control detection, and relates to a detection device for checking the outer dimensions and appearance of an automobile central control assembly. Background Art

[0002] The car's central control system is where all motor vehicle-related functions are gathered. It is located in the middle of the vehicle's dashboard. Its functions include adjusting the vehicle's air-conditioning system, adjusting the use of the multimedia system, and adjusting the use of vehicle-related functions. It is a very important component of a motor vehicle.

[0003] In order to meet customer requirements for product quality, testing equipment is required to check the product's dimensions and appearance before shipment to ensure product quality. The conventional testing method on the market is: after placing the product to be tested in the fixture, the device is started to move the XY axis of the platform to the specified position, and the camera in the device takes pictures for comparison and testing. After the device is tested, the XY axis moves to remove the product. The above testing method has the following limitations:

[0004] ①. There are limitations on the detection position: The existing detection scheme mainly captures the product appearance data for comparison detection by moving the camera installed parallel to the product after the product enters the detection device. This scheme cannot meet the detection needs of multiple surfaces of the product.

[0005] ②. There are limitations in the detection of special dimensions of products; the camera of the device cannot measure the difference in the entire flatness data of the product and cannot measure the shape and size of special-shaped parts.

[0006] ③. Low detection efficiency: Because the existing device can only detect the size and shape of the camera parallel surface, and the image processing must be completed after the image is captured before the standard parts comparison can be carried out to obtain the result, the detection time is long when multiple sizes are operated.

[0007] ④. Poor versatility: New devices need to be purchased based on the different requirements of location, size and characteristics of different products.

[0008] ⑤. High misjudgment rate: Since the fixture and the camera are in a non-transferable state, the product size will be misjudged if the product is not completely placed in the specified position or the carrier does not move to the specified position.

[0009] ⑥. High investment cost: A single device can only test one side of the product. If the product needs to be tested on multiple sides, multiple testing devices will be required. (Especially when both the top and bottom sides need to be tested)

[0010] ⑦. Inconvenient operation: The assembly product is a structural part with a relatively large size and heavy weight. Under the existing inspection mode, personnel need to turn it over frequently during inspection, which is very inconvenient for employees and easily causes bumps and damages to the product.

[0011] ⑧. The test results cannot be saved: The traditional test device images cannot be saved according to the product serial number.

[0012] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. Utility Model Content
