Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, and more specifically, to a plate conveying device with unequal thickness. Background Technology
[0002] Welding between plates of unequal thickness is required in industries such as automobile manufacturing, machining, and large steel structure production. However, existing material transfer methods have several shortcomings: First, many current material transfer operations rely on robotic arms to grasp plates of unequal thickness for relocation, but frequent grasping actions can easily cause wear and tear on the joints and grippers of the robotic arms, leading to higher maintenance costs. Second, the use of pneumatic or hydraulic cylinders to push materials is also widely adopted. During the pushing process, plates of unequal thickness are prone to shifting on the plane, especially during long-distance transport. Small deviations accumulate, eventually causing serious deviations in the positional accuracy of the plates of unequal thickness, affecting the normal operation of subsequent processes.
