AI Technical Summary

Technical Problem

The existing hydrogen fuel cell electrode membrane flatness detection device is prone to damage the electrode membrane during the detection process, resulting in interruption of the ion channel, affecting detection accuracy and battery performance.

Method used

A planarity detection device is designed to achieve point contact and short-term contact between the detection rod and the electrode film through the combination of the support seat, the detection rotor, the marking paper barrel and the detection rod, thereby reducing damage, and avoiding repeated marking of the detection rod at the same position through the rotation and movement of the marking paper barrel.

Benefits of technology

It effectively reduces damage to the electrode film, improves detection accuracy and battery performance evaluation, and the device design improves detection efficiency and service life of the electrode film.

Abstract

The invention relates to the technical field of flatness detection devices, and discloses a flatness detection device and a detection method for hydrogen fuel cell electrode membrane production.The flatness detection device comprises a detection table, a supporting frame is horizontally installed above the detection table in a sliding mode, and the supporting frame is horizontally installed on the upper surface of the detection table in a sliding mode along a straight line; linear lifting equipment is fixedly mounted on the support frame; according to the flatness detection device, through arrangement of the supporting seat, the detection rotary drum, the marking paper tube and the detection rod, when the supporting seat translates, the detection rotary drum rolls and drives the detection rod to rotate, so that the detection rod is close to an electrode film once at equal intervals, and when the contact position of the surface of the electrode film and the detection rod has a bulge, the detection rod cannot be damaged; the detection rod is jacked up to be in contact with the marking paper tube, so that recording points are left on the marking paper tube, the number of the positions of the protrusions on the electrode film can be rapidly recorded, and damage to the electrode film can be reduced due to the fact that the detection rod is in point contact with the electrode film, and the contact time is short.
