Detailed Description
As shown in figures 2 to 7, the light inspection system for the sealing surface of the honeycomb filter element of the utility model comprises a rack 5, a supporting groove 6, a mounting rack 7 and a display screen 8 are arranged on the rack 5,
the top of the support groove 6 is used for clamping and supporting the honeycomb filter element 9, and a light-emitting device 10 is arranged in the support groove 6 and corresponds to the honeycomb filter element 9; when the honeycomb filter element 9 is clamped at the top of the supporting groove 6, the filtering channel 1 inside the honeycomb filter element is arranged along the vertical direction;
the mounting rack 7 is connected with a camera 12 and a brightness switch 13 through a connecting device 11, and the camera 12 and the brightness switch 13 are both positioned above the honeycomb filter element 9 to be inspected;
a box body 14 is arranged in the rack 5, an electric control device 15 is arranged in the box body 14, the electric control device 15 is connected with a storage 16, the electric control device 15 is connected with the camera 12, a brightness switch 13, a light-emitting device 10 and a display screen 8, and the brightness switch 13 is connected with an audible and visual alarm 17.
The connecting device 11 is a three-coordinate apparatus. For example, the structure of a three-coordinate measuring apparatus (Suzhongheng micro-instrument science and technology Co., Ltd.) disclosed in Chinese patent 2018215911646 is adopted. The three-coordinate measuring device facilitates adjustment of the positions of the camera 12 and the brightness switch 13.
The light-emitting device 10 is a plurality of LED lamp beads which are uniformly distributed, and the area surrounded by the LED lamp beads corresponds to the honeycomb filter element 9.
