Embodiment Construction
[0016] The above and other embodiments and advantages of the present invention are clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the present invention.
[0017] In one embodiment, as figure 1 shown. The electric elevator based on machine vision includes an L-shaped base 1, a lifting frame 2 arranged on one side of the L-shaped The heavy assembly 4, and the lifting motor 5 and the lifting shaft assembly 6 arranged on the top of the L-shaped base 1. In this embodiment, the lifting frame 2 and the counterweight assembly 4 can be synchronously lifted and lowered along both sides of the L-shaped base 1 . The lifting motor 5 is transmission-connected to the lifting shaft assembly 6 , and the lifting shaft assembly 6 is transmission-connected to the lifting frame 2 and the counterweight assembly 4 . The lifting shaft assembly 6 is located above the lifting frame 2 an...

The invention provides a machine vision detection system for an electric lift. A camera shooting unit, a to-be-detected light source, a reflector and a controller are included. The to-be-detected light source is arranged at the bottom of an elevating rack and ascends and descends up and down along with the elevating rack. The to-be-detected light source and the camera shooting unit are located above the reflector, the to-be-detected light source ascends and descends up and down relative to the reflector, and the camera shooting unit is fixed relative to the reflector. The camera shooting unit,the reflector and the to-be-detected light source are arranged in a V-shape manner. The to-be-detected light source is imaged on an imaging point of the reflector through the light incidence path, and when the elevating rack ascends and descends up and down, the imaging point position of the reflector changes along the linear path. The camera shooting unit is located on the light reflection pathpassing through the imaging point, and detection images including the image of the to-be-detected light source are obtained through the reflector. The controller detects the current height of the elevating rack according to the edge coordinates of the detection image and the imaging point coordinates in the detection image.
Description
technical field [0001] The invention relates to a machine vision detection system for an electric lift, in particular to a machine vision detection system for an electric lift to detect the current height of a roller table. Background technique [0002] The visual inspection system uses industrial cameras instead of human eyes to complete functions such as recognition, measurement, and positioning. At present, the visual inspection system has been widely used on the production line to realize functions including but not limited to positioning. However, in terms of electric elevators, due to the small lifting range of the roller table of the electric elevator and the small size of the equipment, it is not conducive to the detection of the visual inspection system. Therefore, it is difficult to apply visual inspection in this respect. At present, the only feasible solution is to support the external support and install the visual inspection system on the external support. T...
