Problems solved by technology

With the popularity of multi-point clamping devices, many factories have begun to use this type of mechanism to achieve rapid production. However, it is known that most of the common multi-point clamping devices on the market are designed based on multi-axis robotic arms and have complex structures. The weight and volume are large, the control is difficult and the cost is high. Not all processing manufacturers can afford this capital investment, which discourages the enthusiasm of processing manufacturers to improve the production line, affecting production efficiency and economic benefits

Embodiment 2

[0042] A robot for picking up objects in this embodiment includes a receiving mechanism and a multi-point gripping device, and the multi-point gripping device is located above the receiving mechanism.

[0043] The working process of the robot for picking up items in this embodiment: according to the position of the desired item to be picked, enter the control program. In the initial state, the upper frame slides to the middle position through the left and right sliding mechanism, and the stopper triggers the photoelectric switch to control the motor to stop. drive. In the working state, through the position detection mechanism and the left and right sliding mechanism, the upper frame is controlled to slide in the three positions in the left and right directions, so that the clamping mechanism can clamp the items in these three positions; if the items that are closer to the upper frame , the left and right sliding mechanism drives the upper frame to move left and right, the cla...

Abstract

The invention relates to a multi-point clamping device which comprises an upper-layer frame, a lower-layer frame, a left-right sliding mechanism, a front-back telescopic mechanism, a front-back turnover mechanism, a left-right opening and closing mechanism and a clamping mechanism. The left-right sliding mechanism comprises double-layer tackles and a left-right sliding component driving the upper-layer frame to slide in the left-right direction relative to the lower-layer frame. The upper-layer frame is arranged on the lower-layer frame through the double-layer tackles, and the two double-layer tackles are located at the front end and the rear end of the upper-layer frame respectively. The upper-layer frame is connected with the left-right sliding component, and the lower-layer frame is connected with the left-right sliding component. The front-back telescopic mechanism is installed on the upper-layer frame, the front-back turnover mechanism is installed on the front-back telescopic mechanism, the left-right opening and closing mechanism is installed on the front-back turnover mechanism, and the clamping mechanism for clamping articles is installed on the left-right opening and closing mechanism. The invention further relates to the robot for picking up articles. The structure is simple and reliable, and a plurality of articles at the determined positions can be automatically clamped in sequence. The invention belongs to the field of article carrying instruments.

Description

technical field [0001] The invention relates to the field of material handling equipment, in particular to a multi-point clamping device and a robot for picking up objects. Background technique [0002] In the current assembly line production, the use of multi-point clamping devices to obtain workpieces, parts or products greatly shortens the production cycle and realizes rapid production, which is widely favored by major manufacturers. With the popularity of multi-point clamping devices, many factories have begun to use this type of mechanism to achieve rapid production. However, it is known that most of the common multi-point clamping devices on the market are designed based on multi-axis robotic arms and have complex structures. The weight and volume are large, the control is difficult and the cost is high. Not all processing manufacturers can afford this capital investment, which discourages the enthusiasm of processing manufacturers to improve the production line, and a...
