Description

Technical Field

[0001] This utility model relates to the field of transport flatbed technology, specifically to a high-precision electric sandwich plate. Background Technology

[0002] In modern industrial production processes, electric sandwich pallets are widely used for workpiece transfer and measurement due to their unique structure and convenient operation. The typical workflow is as follows: The workpiece is securely fixed on top of the electric sandwich pallet at the loading station. Then, the automatic navigation mode is activated, and the electric sandwich pallet automatically moves to the measurement station, stopping accurately under the guidance of the guide groove. Next, the electric sandwich pallet enters the positioning mode, precisely reaching the designated position. At this point, the drive wheels descend, cooperating with the ground anchor to guide it into the positioning state, and promptly sends a completion status signal, thereby activating the measuring equipment to accurately measure the workpiece. After measurement, the electric sandwich pallet enters the automatic return mode, the drive wheels rise, and it automatically returns to the loading station, preparing for the next workflow.

[0003] However, existing electric sandwich pallets have revealed serious accuracy issues in practical use. During the transfer process, various factors, such as uneven ground or accumulated errors in the automatic navigation system, cause the electric sandwich pallet to struggle to move precisely to the measurement station along the preset path, resulting in positioning deviations. In positioning mode, although the drive wheel assembly descends to cooperate with the ground anchor for positioning, the tolerances of the mechanical structure itself, wear of positioning components, and the influence of the external environment prevent the electric sandwich pallet from achieving a stable and accurate ideal positioning state. Consequently, when the measuring equipment measures the workpiece, the measurement results contain significant errors, seriously affecting the reliability of product quality inspection and the accuracy of subsequent production and processing.
