[0034] The bipolar plate membrane electrode loading and positioning structure of the utility model includes an upper positioning module, a loading silo module and a lifting silo module. The upper positioning module is installed on the loading silo module, and the lifting silo module is installed below the loading silo module and pushes the upper positioning module to move upward.

[0035] As a preferred embodiment of the utility model, the upper positioning module includes an outer support rod, a material loading in place sensor, a lateral positioning block, a side push cylinder and a top plate, a plurality of the outer support rods are fixed under the top plate, the middle of the top plate is hollow, two of the material loading in place sensors are respectively installed on the two long sides of the top plate, and the positions of the two material loading in place sensors are opposite to each other, and the lateral positioning blocks and the side push cylinders are respectively installed on the four sides on the inner side of the top plate.

[0036] As a preferred embodiment of the present utility model, the loading silo module includes a plurality of long guide rods and a silo bottom plate, the long guide rods are circumferentially mounted on the silo bottom plate, and the top ends of the long guide rods are respectively connected to lateral positioning blocks or side thrust cylinders.

[0037] As a preferred embodiment of the utility model, the jacking silo module includes a loading jacking plate, a jacking guide column and a jacking motor. The jacking guide column is installed below the loading jacking plate, and multiple jacking guide columns are respectively installed on the four corners of the loading jacking plate. The jacking motor is installed in abutment with the bottom of the loading jacking plate.

[0038] As a preferred embodiment of the present utility model, the jacking silo module further includes a jacking guide bushing, and the jacking guide bushing is installed at the bottom end of the jacking guide column.

[0039] With the development of the hydrogen energy industry, the battery field has problems of high material cost and slow speed. The application of electrolyzer membrane electrode alignment assembly test is becoming more and more important. Its precise material positioning is related to the development of the hydrogen fuel cell field and the safety of subsequent detection.

[0040] In a specific implementation of the utility model, the utility model comprises two parts: a lower positioning module and an upper positioning module. In the lower positioning module, the membrane electrode is manually placed on the center of the membrane electrode guide rod tooling plate of the lower fixing tooling in a loading manner.

[0041] The utility model can make the silo positioning and upper part precise transition, smooth and efficient uninterrupted work. The utility model can continuously load and unload materials (unstop loading and unloading) under the condition of uninterrupted equipment detection. Compared with other conventional mechanisms (most of the conventional mechanisms can only roughly position), this mechanism can position multiple materials at a time more accurately by tightening both sides of the cylinder.

[0042] The workflow of this utility model is as follows:

[0043] Step 1: Place multiple bipolar plates or membrane electrodes on the loading silo.

[0044] Step 2: The bottom mechanism lifts the material in the silo up, and the silo positioning rod plays a guiding and positioning role.

[0045] Step 3: The material on the silo rises to a certain height and the clamping mechanism is positioned above it.

[0046] The column design of the loading positioning mechanism of the utility model can accurately and efficiently position the bipolar plate or membrane electrode loading. The utility model has a simple structure and high stability, can load materials uninterruptedly (loading station A and loading station B are used uninterruptedly), and can load multiple pieces at a time. The long guide rod and the short guide rod can have a good transition and can ensure their positioning accuracy. After the utility model is lifted from the loading position to the lifting position, the rear clamping cylinder is precisely positioned.
