Automobile stamping part taking-placing rapid conveying device

Abstract

The invention discloses an automobile stamping part taking-placing rapid conveying device which comprises a rocker mechanism, a grab mechanism, a direction control mechanism and a grab placing mechanism; the rocker mechanism comprises a rocker unit and a driving motor which are arranged in parallel, the rocker unit comprises a base, a left rocker and a right rocker, the left rocker and the right rocker are connected through a connecting rod, and the rockers perform left and right swinging actions under the action of the driving motor; the grab mechanism comprises a grab frame, a grab and a grab cylinder; the direction control mechanism comprises a double-acting cylinder, a left spring and a right spring; and the grab placing mechanism comprises an inner positioning block and an outer positioning block, and the outer positioning block is provided with a limiting block. Conveying of a stamping part can be completed by using one motor, so that the conveying time is greatly saved, and theequipment takt is improved; and the conveying efficiency is high, time and labor are saved, the taking and placing positions of the stamping part are high in precision, the principle is simple, the conveying operation of the stamping part can be completed only through drive of one motor, and the cost is saved.

Description

technical field [0001] The invention relates to a fast pick-and-place transfer device for automobile stamping parts, which belongs to the technical field of article transfer. Background technique [0002] At present, in the automatic welding production line in the automobile welding workshop, some stamping parts such as fenders, top cover outer panels, side panel outer panels, etc., are first placed by workers at the upper station, and then the stamping parts are placed by the handling equipment. Transport it to the robot grabbing station, and the robot grabs it to the body welding station for welding. [0003] Because when the robot grabs the stamping parts, the position of the stamping parts is required to be accurate. Therefore, there are high requirements for the position accuracy of the handling equipment. At present, multiple positioning pins are mainly used to locate the stamping parts. The stamping parts are provided with pin holes, and the stamping parts are verti...

AI Technical Summary

Problems solved by technology

This may not be able to meet the high takt and high efficiency requirements of the automated production line

[0006] It can be seen from the above that the existing stamping parts handling has the following problems: 1. The handling equipment for fine positioning, the handling process consists of three discontinuous processes, and there are three motor operation cycles, which will affect the efficiency of the automated production line if the time is long

2. The linear motion in three different directions is driven by a motor to change the rotary motion into a linear motion, which requires a motion conversion device, such as a rack and pinion, a sprocket chain, a nut screw, etc. In addition, a motor is required for translation. One is required for descending, which will increase the cost of the production line

3. Three processes are required for one operation, and a locking device needs to be added to ensure the precise position of the gripper, which again increases the cost of the equipment
