Overturning unit of soft package lithium battery and surface defect detection device

Abstract

The invention discloses an overturning unit of a soft package lithium battery and a surface defect detection device. The overturning unit comprises a front overturning assembly and a rear overturningassembly; the front overturning assembly comprises a vertical supporting plate, a first supporting piece, a first bearing plate, an air cylinder mounting plate, a telescopic air cylinder, a first bearing seat, a first rotating shaft and a first motor driver. The rear overturning assembly comprises a second supporting piece, a second bearing plate, a second bearing seat, a second rotating shaft anda second motor driver; the first rotating shaft is driven by the first motor to drive the vertical supporting plate to rotate, the soft package lithium battery is overturned to be in a vertical state, the second rotating shaft is driven by the second motor to drive the second supporting piece to rotate, and overturning of the soft package lithium battery is achieved. According to the invention, overturning and surface detection of the soft package lithium battery can be realized, and the blank of the prior art is filled. The overturning unit is simple in structure, stable in operation, low inproduction cost and easy to popularize, and abrasion to the soft package lithium battery can be avoided in the overturning process.

Description

technical field [0001] The invention relates to the field of new energy manufacturing, in particular to a flipping unit for a soft-pack lithium battery, and also to a surface defect detection device for a soft-pack lithium battery. Background technique [0002] With the continuous development of green energy, lithium batteries, as one of the most promising clean energy sources, shine in various industries. Due to its superior performance and flexible size, the proportion of soft-pack lithium batteries in the market is also increasing, and the output is also increasing year by year. However, if the aluminum-plastic film on the surface of the pouch battery is damaged, it will cause the internal circulation of the battery to be disordered, cause a short circuit, and cause fire and other dangerous situations. Therefore, there is a great potential market demand for identifying defects on the surface of batteries and eliminating and classifying defective products. With the rap...

Problems solved by technology

[0005] In the above scheme, the main objects are shell-type batteries and beverage bags. In order to ensure that the batteries do not fall during the flipping process, the batteries must always be in a clamped or sucked state, and the force is difficult to control. Since the aluminum-plastic film is easy to wear, It is not suitable for objects with aluminum-plastic film as the surface. It is very easy to cause secondary wear and tear on them by mechanical mechanism clamping or adsorption, so that the object becomes a defective product

On the other hand, this type of turning device requires high precision and requires equipment such as mechanical arms, so the cost is relatively high
