Embodiment 1
[0019] Embodiment 1 of a coil positioning method at a coil collecting station provided by the present invention, combining figure 1 A flow chart of a coil positioning method at a coil collection station, which may specifically include:
[0020] S101. Receive the position image information of the trolley when the trolley transports the coil to the coil unloading position collected by the camera;
[0021] S102. Determine the number of pixels of the coil on both sides of the center line of the C-shaped hook on the center line of the C-shaped hook of the coil tightly held by the two arms of the trolley through the position image information;
[0022] S103 , judging whether the difference in the number of pixels of the coil on both sides of the centerline of the C-shaped hook exceeds the allowable error range, and if so, adjusting the position of the coil until it meets the allowable error range.
[0023] Specifically, after the trolley transports the coil to the unloading positio...

The invention discloses a coil collection station coil positioning method, so as to solve the positioning problems that positioning is inaccurate when an encoder is used in the prior art and the gravity center of the coil is not fixed in the case of coil collection. The coil collection station coil positioning method comprises steps: trolley position image information when the trolley conveys the coil to a coil unloading position acquired by a camera is received; through the position image information, pixel numbers of the coil at two sides of a central line of a C-type hook when the coil tightly held by two holding arms of the trolley uses the central line of the C-type hook as a standard are determined; whether the difference of the pixel numbers of the coil at two sides of the central line of the C-type hook exceeds an error permission range is judged, and if yes, the coil position is adjusted until to meet the error permission range. According to the coil collection station coil positioning method, the problem of inaccurate encoder positioning in the prior art can be solved, positioning accuracy is improved, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the field of automatic control, in particular to a coil positioning method at a coil collecting station. Background technique [0002] In the prior art, the control of the high-speed wire coil collection station is realized by holding the steel coil tightly by the moving arm and the fixed arm of the trolley, transporting the coil to the C-shaped hook, unloading the coil after centering and positioning. Wherein, the distance between the movable arm and the fixed arm is a constant distance, and the distance traveled by the movable arm to clamp the steel coil is subtracted from the constant distance to obtain the length of the coil. The position of the trolley is positioned by the encoder. Measure the actual distance between the trolley and the centerline of the C-shaped hook when the trolley is in zero position, and subtract half the distance from the steel coil from the actual distance between the trolley and the centerline of t...
