H1H2 Dedicated Lithium Battery Inspection Equipment

For the quality inspection of battery shell mounting holes and surfaces in the new energy & automotive industry, a detection system for battery box surface defects, dimensions, and positional accuracy relative to product processing reference points has been developed. Due to the large size of the product, the corresponding detection accuracy cannot be achieved when the camera covers the entire field of view, so a small field of view is used to measure the positional accuracy and dimensions of all battery shell mounting holes based on the established product coordinate system. After visual calibration, the pixel coordinate system of the camera is mapped to the axis system of the machine, thereby establishing the entire product coordinate system on the vision system, accurately measuring the positional accuracy and size information of each mounting hole. The presence of surface defects such as missing welding or excess welding on the battery shell surface is accurately judged based on image grayscale information.
  • Size and appearance can be detected simultaneously
  • Strong compatibility: One machine can accommodate multiple products
  • Quick product switching: 
    The machine can accommodate multiple products, 
    and the product formula file can be quickly switched through software
  • Fast detection speed: 
    There are more than 800 detection points on the product, 
    achieving 255s per piece
  • Wide coverage: 
    Can cover the detection needs of 5 sides of the product

High-Precision Alignment and Lamination of Automotive Windshields and PVD Films

The method of bidirectional alignment lamination of PVD film and glass includes the following steps: the alignment platform module drives the film on the alignment platform tray to move left or right and forward or backward to a certain position, exposing the adjacent sides of the film and the adjacent sides of the glass relative to the film; camera takes a photo; the bidirectional alignment lamination mechanism records the position of the adjacent sides of the film and the position of the adjacent sides of the glass relative to the film through the camera; the position deviation between the film and the glass is calculated based on the film edge and glass edge recorded by the camera; finally, the alignment platform module aligns the center of the film with the center of the glass.
  • Simple adjustment:
    Just need to make sure the film and glass appear in the camera,
    The alignment accuracy is not significantly affected after the camera moves
  • Fixed glass:
    During and after alignment, the glass does not move,
    Reducing errors caused by movement
  • Simple coordinate integration:
    Coordinate integration is simple,
    There is no error in coordinate integration
  • Separate photography:
    The camera takes photos of the film 
    and glass separately without interference

Universal Joint Cross Shaft Appearance Defect Detection

The cross shaft is a component that enables the transmission of power at varying angles, used in positions where the direction of the drive shaft needs to be changed. It is the 'joint' part of the universal transmission device in the automotive drive system, and its manufacturing precision is very important to ensure the safety of the vehicle. It requires full inspection of the cold extruded cross shaft blanks. Due to the mass production of small cross shafts, with tens of thousands of cold extruded blanks produced daily per machine, manual inspection is inefficient and prone to missed and false detections. Therefore, there is an urgent need to research an efficient, non-destructive, and fully automatic detection technology.

The key project detection of the cross shaft analyzes a certain cross shaft cold extrusion blank. During the cold extrusion process, due to substandard raw material quality, unstable pressure from the press advancement, unstable locking pressure of the press, oil leaks from the cylinder or distributor, and loosening of positioning pins, the following issues are likely to occur: (1) Length of both ends of the cross shaft (37.20.2) mm out of tolerance; (2) Inner and outer height of the cross shaft (10.70.2) mm and 15.40-0.4mm out of tolerance; (3) Four shaft diameters (10.28+0.10) mm too large; (4) Straightness of the shaft diameter out of tolerance, shaft bending; (5) Misalignment when closing the upper and lower molds at the shaft diameter; (6) End face cracks, shaft diameter cracks, mold breakage, and other appearance issues. From the above detection focus, there is detection of dimensional errors, detection of form and position errors, and detection of appearance quality. The inspection of appearance must be achieved through a visual recognition system, which consists of a cross shaft holder and rotator, workstation switching mechanism, smart camera, and detection control system, capable of detecting dimensional errors and form and position errors of the cross shaft as well as automatic sorting, thus realizing the fully automated production of automotive cross shaft cold extrusion.

    automotive cross shaft cold extrusion through automatic sorting
