Automatic turnover device

Abstract

The invention discloses an automatic turnover device. The automatic turnover device comprises a worktable, a turnover frame body, a conveying mechanism, a turnover mechanism and a positioning mechanism, wherein the worktable is provided with symmetric worktable outer plates, the turnover frame body is provided with a conveying mechanism bracket transverse plate I and a conveying mechanism brackettransverse plate II; the conveying mechanism of two sets of conveyor belt wheel sets is capable of vertical tight clamping, a turnover mechanism and a positioning mechanism are arranged, wherein the two sets of conveying mechanisms a conveying belt wheel set is provided with the functions of capable of vertically clamping, longitudinal distance adjusting and transverse conveying; the turnover mechanism is connected with the turnover frame body and the worktable outer plates, and the positioning mechanism is provided with photosensitive sensors and push rod air cylinders; the two sets of conveying belt wheel sets are correspondingly fixed on the opposite sides of the turnover frame body, and the photosensitive sensors are correspondingly fixed on the two ends of the conveying mechanism bracket transverse plate I and / or the two ends of the conveying mechanism bracket transverse plate II, and the push rod air cylinders are fixed at the positions close to the outlet ends of the conveying belt wheel sets and are controlled to stretch through the photosensitive sensors. According to the device, automatic machining is adopted to replace manual work so that manual operation damage can be reduced, the turnover requirements of reversed parts with different sizes can be met, the power consumption is low, operation is stable and reliable, and the turnover device is particularly suitable for machining of a fuel cell unipolar plate, a bipolar plate and a membrane electrode.

Description

technical field [0001] The invention relates to an automatic turning device, which belongs to the technical field of auxiliary equipment for automatic production and processing, and is especially suitable for automatic production of fuel cells. Background technique [0002] In various fields, due to the advantages of high work efficiency, good quality, and low cost, automated production has gradually replaced manual production. Among them, flipping, as a basic processing method in the production process, exists widely in various fields. In the field of fuel cell automation production, the processing of bipolar plates involves the processing of double-sided sealing structures. First, one side is processed, after drying, the other side is processed by turning over, and then dried again, and finally the bipolar plate is completed. Processing of the sealing structure; in the prior art, when processing the sealing structure of the bipolar plate, one side is processed first, and a...

Problems solved by technology

Although these two existing technologies can achieve the purpose of turning over, they can only turn over a workpiece with a single fixed size, which cannot be adapted to the production application of the product size. Moreover, the above two turning devices are only designed for the preparation of membrane electrodes. The applicability of the flipping operation required in the processing of other sheet workpieces is insufficient, and the function is too single, which is not conducive to the structural optimization of the continuous operation of the automated production line
