Fully automatic ocv&ir testing, tab cutting and spot welding all-in-one machine

Abstract

The invention discloses a full-automatic OCV&IR testing, pole cutting and spot welding integrated machine, which includes a frame, a cell feeding mechanism, a first feeding mechanism, a cell positioning mechanism, a turntable feeding mechanism, a first turntable mechanism, a test The workstation, the second feeding mechanism, the tab cutting workstation, the turntable unloading mechanism, the second turntable mechanism, the protective plate feeding mechanism, the first welding workstation, the second welding workstation, the third feeding mechanism and the control box. The above-mentioned mechanisms or workstations are sequentially arranged on the rack, so that the batteries can be automatically circulated between the front and rear mechanisms or workstations. This all-in-one machine does not need manual OCV&IR testing, lug removal and welding, and there will be no missed or wrong measurements, and there will be no uneven length of the tabs, and it can reduce point deviation, ignition, and leaks. The situation can ensure the quality of the finished battery. At the same time, it is easy to operate, saves human resources, and reduces costs; it has a high degree of automation and strong compatibility, and can be widely used in the battery packaging industry.

Description

technical field [0001] The invention relates to a lithium battery processing equipment, in particular to an integrated machine capable of detecting battery cells, cutting tabs and welding protective plates. Background technique [0002] At present, in the production process of mobile phone battery packaging, the first step is to conduct OCV&IR testing, tab cutting, and welding of protective plates on incoming batteries. Among them, the OCV&IR test refers to the detection of the voltage, internal resistance and other properties of the battery cell. The purpose is to ensure the performance of the battery in subsequent processing; The reason is that in order to ensure the reliability and operability of the product, the length reserved by the supplier is often higher than the length required by the actual customer. Therefore, it is necessary to cut the length of the positive and negative electrodes of the tab into The required standard length; after the tabs are trimmed, use a ...

Problems solved by technology

In addition to the problems of high labor intensity and low efficiency, this method also has the following disadvantages: 1. Manual OCV&IR testing has many uncertainties, including missed testing, mistesting, etc., and some defective products cannot be Accurate and timely selection will lead to the flow of defective products to semi-finished products and finished products, resulting in unnecessary waste of costs; 2. Inaccurate battery positioning may occur when manually cutting tabs, resulting in missed cuts or two poles after cutting The length of the ears is different, which affects the quality (performance, size) of the battery in the later stage of processing; 3. Due to the poor positioning of the battery cell during welding, it may cause point deviation, ignition, leakage, etc., which will affect the quality of the battery. performance

To sum up, in the existing production process, due to manual work, its own quality, work fatigue and other factors will affect the performance of the finished battery
