Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as Figure 1 to Figure 3 As shown, a pouch battery dual-channel size detection device of the present invention includes a detection platform 1, a feeding module 91, and a clamping module 92. One end of the feeding module 91 is connected to the detection platform 1, and the other end thereof is connected to the upstream process. The detection platform 1 There are two sets of detection channels, and each set of detection channels is equipped with a visual detection station and a pressure detection station. The clamping module 92 grabs the pouch battery to be tested from the feeding module 91 and sends it to the visual detection station or pressure detection station. A visual measuring mechanism 8 is provided on the visual testing station,...

Abstract

The invention relates to the field of battery detection, in particular to a soft package battery dual-channel size detection method and a soft package battery dual-channel size detection device. The method comprises the following steps: S1, a feeding module conveys a to-be-detected soft package battery product generated in a previous process to a detection platform, and a clamping module grabs the to-be-detected soft package battery product and conveys the to-be-detected soft package battery product to a visual detection station or a pressure detection station; s2, after the product is conveyed to a pressure detection station, the product is placed on a constant force distance measurement mechanism, downward pressure is applied to the product, and the thickness distance of the product is measured through the value of the pressure borne by the product; and S3, after the product is conveyed to the visual inspection station, the product is placed on a visual measurement mechanism, and an image of the product is collected to measure the outer contour size of the product. The constant force distance measuring mechanism outputs constant force to control the deformation degree of the soft package product, a constant force difference mode is used in a thickness measuring mode, and it is guaranteed that the pressure is controllable. A visual detection mechanism with a large-view double-telecentric lens is adopted for outer contour dimension measurement, overlarge distortion of images is avoided as much as possible, and measurement precision and efficiency are guaranteed.

Description

technical field [0001] The invention relates to the field of battery detection, in particular to a double-channel size detection method and device for a pouch battery. Background technique [0002] At present, the existing soft-pack battery measurement equipment uses small field of view optical lenses and PPGH mode measurement methods, resulting in slow measurement speed, long debugging and replacement cycles, and loss of control over the deformation of soft-pack products, resulting in poor measurement accuracy. Contents of the invention [0003] The invention provides a double-channel size detection method and device for a pouch battery, aiming at solving the problems of low efficiency and poor precision of the existing pouch battery size test. [0004] The invention provides a double-channel size detection method for a pouch battery, comprising the following steps: [0005] S1. The feeding module transports the pouch battery product to be tested produced in the previous...
