Problems solved by technology

[0003] At present, the mechanism for picking workpieces is commonly used in clamping jaws or suction cups. In order to improve the picking efficiency, multiple picking mechanisms are often used to pick up at the same time. Since the picking mechanisms are connected by structural parts, the picked up The position of adjacent workpieces remains unchanged, which requires limiting the relative positions of the entire assembly line or production line between multiple stations, which virtually increases the spatial layout requirements of the assembly line and production line; on the other hand, there is a visual inspection process during the picking process. The distance between the two cameras does not match the position of the adjacent workpiece being picked up. If the size between the two cameras needs to be coordinated, the space layout will inevitably be wasted

Abstract

The invention provides a variable-pitch mechanism. The variable-pitch mechanism comprises a variable-pitch unit body provided with a plurality of pick-up units; the variable-pitch unit body comprisesa variable-pitch driver, a variable-pitch movable assembly, variable-pitch fixed plates and a variable-pitch base frame; and the variable-pitch driver drives the variable-pitch movable assembly to move, so that the distance between every two adjacent variable-pitch fixed plates becomes larger or reduced. The invention further relates to a pick-up device with a pitch-variable function. According tothe variable-pitch mechanism, automatic switching of the distances between two adjacent pick-up units is realized through structural design; meanwhile, vacuum negative pressure and magnetic attraction are combined to achieve rapid pickup of to-be-picked workpieces; the device is ingenious in structure, reasonable in design and capable of solving the problem of spacing changing of different stations of the multiple pick-up structures; and meanwhile, the pick-up process is efficient and accurate, the pick-up clamping force is continuously adjustable, and the automatic feeding and discharging requirements of the workpieces are met.

technical field [0001] The invention belongs to the field of automation, and in particular relates to a distance-variable mechanism and a pick-up device with variable distance. Background technique [0002] With the continuous improvement of industrial automation, the manufacturing industry is gradually realizing intelligence and unmanned; especially for the device for loading and unloading workpieces, the degree of mechanization determines the efficiency of the overall production. [0003] At present, the mechanism for picking up workpieces is commonly used in clamping jaws or suction cups. In order to improve the picking efficiency, multiple picking mechanisms are often used to pick up at the same time. Since the picking mechanisms are connected by structural parts, the picked up The position of adjacent workpieces remains unchanged, which requires limiting the relative positions of the entire assembly line or production line between multiple stations, which virtually incr...
