What is a car check?

Now many large car factories produce cars to use the tester to test, what is the auto tester? Automobile inspection tool is a special inspection equipment used to measure and evaluate the size and quality of parts. In the parts production site, through the inspection tool to achieve the online inspection of parts, to this end, the parts need to be accurately installed on the inspection tool, and then through visual inspection, or measuring scale, or calipers on the parts of the surface, the periphery of the inspection, you can also use the inspection pin or visual inspection of the different nature of the holes on the parts and the connection position between the parts. In order to ensure that the rapid judgment of the quality status of the parts is achieved during production, after understanding what is the automobile inspection tool, how does it work? This should be a lot of people want to know, the following by Ruicheng inspection technicians for everyone to share:

The working principle of the automotive inspection tool is to use high-speed and high-precision visual processing technology to automatically detect various Posting errors and welding defects on the pcb board. The PCB board can range from fine-pitch high-density board to low-density large-size board, and provide online inspection solutions, so as to promote the progress of production efficiency and welding quality. By using AOI as a tool to reduce defects, automotive inspection tools can find and eliminate errors early in the assembly process to achieve good process control.

For some extremely important functional dimensions on the parts, it is also possible to use the gage for numerical detection. Usually, the precise coordinate value of the parts based on the coordinate system of the body can not be obtained directly with the help of the gage, but the parts are placed on the gage and measured by the coordinate measuring machine. The structure of modern gage is designed with consideration that it can be used as a measuring bracket. However, when the online inspection function of the gage and the measuring support function cannot be met at the same time, the online inspection function of the gage should be met first.

The design of the inspection tool must be in accordance with the final 3D data and 2D drawings provided by the customer, and the 3D data must have the correct automobile coordinate system. The design and manufacture of the inspection tool need to be approved by the customer before processing and delivery. The measuring support is an auxiliary support for measuring parts with the coordinate measuring machine. All of its support surfaces (points) and positioning datum surfaces must be milled according to the CAD data of the part, and the measuring brackets of some special parts should also have the function of partial gauges.
