Lithium battery module automatic production line planning -Lithium - Ion Battery Equipment
With the continuous popularity of the new energy industry and the gradual clarification of various standards, the demand for power lithium battery modules and pACK automatic assembly lines is also increasing. Especially since the second half of 2015, many domestic cell factories and pACK factories have increased investment in automated production lines in order to meet national access standards, improve product consistency and expand production.
Due to the particularity of the industry process, it is difficult to form a unified standard for the current production lines with many models, and the information and conditions that customers need to clearly prepare for themselves are relatively vague, so today we will briefly introduce the company when faced with the needs of automated production lines. , It is necessary to prepare the basic conditions, so that we can quickly connect with equipment suppliers and purchase automated production lines that conform to market laws and suit our own technical standards.(Lithium - Ion Battery Equipment)
01. Understanding of customer process requirements
The first condition is naturally that some companies should have a "mature and unified process, including assembly methods, testing content and accuracy requirements. For example, should the incoming battery cells be scanned? Whether the barcode should be bound? Whether the battery cells should be sorted. ? The number of bins to be sorted? Does it include the MES system? What data does the MES system need to collect and upload, etc...
These are the soul of the entire production line design. All equipment configurations are based on customer process requirements. It is best to have actual usage reports, mature brands and models in use, and existing bottleneck analysis, so that Reasonable selection and arrangement during automatic production line planning. And considering the compatibility of the production line, it is best to plan the scope of process changes in the early stage.
After there are certain process requirements, "the final version of the product digital model and real sample" is also required. The final version here is very important, because the standards of the power lithium battery industry are not uniform, and the products of each company are not completely consistent, and even their own The products have various series and are constantly updated. Based on this, when designing the production line, try to supply the latest, or the type of products with the largest demand for order production.
It is better not only to have digital models, but also to have actual products, so that details and compatibility can be more perfect in the early design. We have also encountered obvious errors between the customer's drawing tolerance range and the actual sample, which created a lot of obstacles in the commissioning stage of the entire line, which delayed the delivery of the entire line.
At the same time, if it is possible to predict future product changes, it can be proposed at the time of design, and the range of the maximum and minimum sizes can be reserved, so that the production line supplier can carry out work on non-standard parts such as tooling fixture tray grippers in the early stage. With the flexible design, once the product type is changed in the future, the related accessories can be quickly replaced and directly connected to the production without secondary costs.
After completing the above two "hard standards", it is the core "production takt demand" of a production line, which is also the most difficult. In fact, the level of the automatic production line is based on three standards "stability, compatibility, and compliance with the rhythm requirements". Since the current automated production line uses a large number of robots, after the debugging is completed, the production line tends to be stable. Unlike the previous production line that was widely used in the double-speed chain, with the extension of the use time, the accuracy declines and leads to problems. continuously.
