[0030] The detection assembly 3 includes a detection frame 301, a bottom slider 302, an inner slide groove 303, an electric rod 304, a mobile frame 305, a side slider 306, an infrared generator 307, an infrared receiver 308, a scale 309 and an alarm 310. The detection frame 301 is in the shape of a "door". The bottom of the detection frame 301 is fixedly connected with the bottom slider 302. The inner front and rear side walls of the detection frame 301 are provided with inner slide grooves 303. The number of the inner slide grooves 303 is set to two and is symmetrically arranged front and back. The inner top surface of the detection frame 301 is fixedly connected with the electric rod 304. The bottom of the electric rod 304 is fixedly connected with the mobile frame 305. The mobile frame 305 is in the shape of a "door". The front and rear side walls of the mobile frame 305 are fixedly connected with the side slider 306. 06. There are two side sliders 306, which are symmetrically distributed on the front and rear sides of the moving frame 305. The side sliders 306 are both located inside the inner slide groove 303. The front and rear side walls inside the moving frame 305 are respectively fixedly connected with an infrared generator 307 and an infrared receiver 308. The infrared generator 307 and the infrared receiver 308 are located on the same horizontal line and are correspondingly arranged front and back to detect the horizontality of the prototype model.

When the infrared receiver 308 cannot receive infrared rays, the alarm 310 sounds an alarm, and the motor 207 stops working, indicating that the height of the hand model here is too high. Then start the electric rod 304 to raise the height of the mobile frame 305 until the infrared receiver 308 receives infrared rays. At this time, the pointer on the mobile frame 305 is aligned with the scale. 309 indicates the current height, so as to obtain the over-height dimension, which is convenient for subsequent trimming; the electric rod 304 can also be adjusted to make the infrared receiver 308 in a critical state of not receiving infrared rays, and then the detection frame 301 is moved. When the infrared receiver 308 receives infrared rays, it means that the height of the hand model here is too low, and then the electric rod 304 is started to move the moving frame 305 downward. When the infrared receiver 308 cannot receive infrared rays, the electric rod 304 stops. At this time, the pointer and the scale 309 on the moving frame 305 indicate the current height, so as to obtain the over-low dimension, and detect whether it is within the error range. If not, the hand model is unqualified. Both detection states can be set by yourself.
