Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment, and in particular relates to a flexible wire taking and placing device. Background Art

[0002] With the advancement of science and technology, the processing requirements of various products are increasing, and the flexible pick-and-place device suitable for flexible production lines is becoming more and more important. For example, in the automotive industry, in order to meet the needs of different consumers, each automobile OEM launches a large number of new models every year, and each of them usually needs to install various required parts on the door panels of cars and buses by welding. Before welding, the workpiece usually needs to be installed on the workpiece mounting seat first. After welding is completed, the workpiece needs to be removed from the workpiece mounting seat and then a new workpiece is installed. In the prior art, the process of picking and placing parts is all completed by manual operation, or by a combination of machine and manual operation. Specifically: first, the workpiece is manually installed on a device that can achieve lifting and pressing, and then the device is pressed down on the workpiece mounting seat to transfer and install the workpiece on the workpiece mounting seat. After the processing is completed, the workpiece is lifted by the device to complete the workpiece from the workpiece mounting seat, and then the processed workpiece is removed from the device manually. The method of completing it entirely by manual operation has a large workload, and the accuracy and tightness of the installation are not easy to guarantee, which is easy to cause unstable production quality or safety accidents. The existing machine combined with manual method can ensure the accuracy and tightness of the workpiece when it is installed on the workpiece mounting seat, but when installing the workpiece on the equipment that can achieve lifting and pressing, people need to bend down and drill under the equipment to install it, which is very inconvenient, time-consuming and labor-intensive. Therefore, people hope to obtain a pick-and-place device that can ensure the installation accuracy and tightness of the workpiece and is easy to operate when people pick up and put parts in the equipment.

[0021] The method of using the flexible wire picking and placing device of the utility model:

[0022] (1) When it is necessary to place a workpiece on the workpiece mounting seat: the pick-and-place plate group with the workpiece to be processed is pressed down to place the workpiece on the workpiece mounting seat transported thereto. Specifically, the flip plate frame is sucked by the workpiece to place the workpiece; before that, the flip plate frame on the pick-and-place plate group is driven to flip relative to the fixed plate frame to an angle that is convenient for the operator to install the workpiece to be processed on the flip plate frame, and then the workpiece to be processed is manually installed on the flip plate frame. The flip plate frame sucks the workpiece through its workpiece suction cup, and then the flip plate frame on the pick-and-place plate group is driven to return to a position parallel to the fixed plate frame, so as to prepare for placing the workpiece on the workpiece mounting seat;

[0023] (2) When it is necessary to pick up a workpiece from the workpiece mounting seat: the workpiece mounting seat conveyed to the bottom is picked up by pressing down the pick-and-place plate group. Specifically, the workpiece is picked up by the workpiece suction cup on the flip plate frame. After the pick-and-place device picks up the workpiece mounting seat, the pick-and-place plate group is driven to return to its original position, and then the flip plate frame on the pick-and-place plate group is driven to flip relative to the fixed plate frame to an angle that is convenient for the operator to remove the processed workpiece. The processed workpiece is then manually removed from the flip plate frame, and a new workpiece to be processed is installed. The flip plate frame on the pick-and-place plate group is then driven to return to a position parallel to the fixed plate frame, so as to prepare for placing the new workpiece to be processed on the workpiece mounting seat.

[0024] The flexible wire picking and placing device of the utility model has an ingenious structure. While ensuring the installation accuracy and tightness of the workpiece, it can make the combination of manual labor and machine very smooth. Removing workpieces from the picking and placing device and installing new workpieces are very ergonomic, which greatly reduces the operation difficulty and operation intensity, makes it easier to ensure the installation quality, and also improves production efficiency. It is highly practical and worthy of promotion.

[0025] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
