With the improvement of science and technology and the promotion of environmental awareness, the utilization of new energy is more and more extensive, the market scale of new energy automobiles is continuously enlarged, the demand of power batteries is rapidly increased, and the capacity scale of large battery enterprises at home and abroad is enlarged. Along with the expansion of the industrial scale of the power battery, the production quality of the power battery is more and more emphasized, the appearance defect of the battery in the power battery is a type of the poor power battery, and the poor appearance directly affects the later production and use of the power battery, for example, the large wave of the top cover, the surface step, the upwarp of the explosion-proof valve, the scratch, the electrolyte pollution, the dirt, the pit, the damage and the like can affect the subsequent power battery pack assembly, and even cause the potential safety hazard to the subsequent use, so the appearance detection process of the power battery cannot be ignored.

The appearance detection of the traditional product is usually manual visual detection, the subjectivity of people is strong, and the space and time resolution ratio of human eyes is limited, so that the problems of high manpower consumption, low efficiency and detection omission exist, and the detection requirements of high speed and high accuracy in modern industry are difficult to meet.

In order to improve detection efficiency and detection quality, various automatic appearance detection equipment for detecting appearance through machine vision images appears, and in order to accelerate the detection speed, an automatic conveying mechanism is further provided for automatically conveying products to corresponding detection positions.

However, the inventor has noticed that the feeding means for supplying the products to the automatic conveying mechanism is still manual feeding, and the products are manually placed in the feeding area of the automatic conveying mechanism by a human, and therefore, there is a case that the feeding is not neat. When the irregular products reach the corresponding detection positions, the deviation of the products relative to the detection positions causes that part of the positions of the products exceed the detection range, thereby causing low detection accuracy.

In order to avoid the condition that products are not neat on the automatic conveying mechanism due to feeding, the applicant researches and discovers that the products can be corrected before reaching the detection position, so that the products do not exceed the detection range when reaching the corresponding detection position, and the detection accuracy is improved.

In view of the above, the inventors of the present invention have conducted extensive studies to design an appearance inspection apparatus, which, on one hand, replaces manual feeding with machine feeding to improve the feeding efficiency, and on the other hand, after feeding and before the product reaches the inspection position, provides an alignment mechanism to align all the products until the end surfaces of the products are parallel to the predetermined plane, so that the products do not exceed the inspection range when reaching the corresponding inspection position, thereby improving the inspection accuracy.
