Description

Technical Field

[0001] The utility model relates to the technical field of mechanical automation, in particular to a detection device for automatic loading and unloading. Background Art

[0002] With the advancement of mobile phone technology, phones are becoming thinner and their components are arranged more compactly. Consequently, the requirements for mobile phone components in production are naturally becoming increasingly stringent. For example, the flatness requirements for mobile phone mid-boards are also becoming increasingly stringent. Flatness is a key verification parameter for mobile phone mid-boards, used to detect deformation. The larger the flatness coefficient, the more severe the deformation. The distance parameter from each point to the ideal plane can be used to determine the location of the most severe deformation, allowing for verification.

[0003] The front of the mobile phone's mid-plate is used to install the screen, motherboard and various parts, and the back of the mobile phone's mid-plate is used to install the battery and back cover. If the mobile phone's mid-plate is deformed, there will be large errors in the assembly of various parts of the mobile phone, and even some parts of the mobile phone cannot be assembled, affecting the production progress.

[0004] Currently, most companies still rely on manual labor to inspect the flatness of mobile phone mid-plates, including feeding, sorting, and testing. This results in a low level of automation. Manual feeding is not only costly, but also unsafe and inefficient. Manual inspections are subject to human error, resulting in poor results, high labor costs, and low efficiency. After inspection, qualified and unqualified products must be manually sorted, which can lead to collisions during handling, damaging the product and increasing production costs and impacting efficiency.
