[0038] The present invention will be further described below with reference to the drawings and embodiments.
[0039] Such as figure 1 As shown, the missing needle detection device for the head of a stapler with a handle based on the principle of reflection imaging includes a computer 1, a camera 2, a light source lamp 3, and a stapler positioning device 4. The camera 2 is composed of a CMOS image sensor and a lens. The stapler positioning device 4 includes a base 5, a stapler clamp 6, a light source frame 7, a camera frame 8, a column 9, and lifting mechanisms 10, 11, and 12.
[0040]A column 9 is fixedly installed on the base 5, and lifting mechanisms 10, 11, 12 are installed on the column 9 from top to bottom, a lens frame 8 is fixedly installed on the lifting mechanism 10, and a light source frame 7 and a light source frame 7 are fixedly mounted on the lifting mechanism 11 The ring light source lamp 3 is fixed on the upper part, and the stapler clamp 6 is fixedly installed on...
