Function and principle of lithium battery sorting machine
Lithium battery sorting machine is a device used to sort the AC internal resistance and open circuit voltage of cylindrical lithium batteries. With high precision internal resistance, voltage active test system(New sorting machine can customize code scanning function), the device based on the computer software set on the internal resistance, voltage value of the battery into the specified gear, using servo motor precision control, belt synchronization transmission, greatly improving the test speed and test data stability.
The function of lithium battery sorting machine
- lithium battery sorter adopts new hopper type automatic feeding structure, high speed and stable feeding, no impact and scratch on the battery; and suitable for different material boxes directly manual whole box feeding, can realize uninterrupted production.
- 18650 lithium battery sorter adopts high precision and high stability internal resistance detector for the testing part and high speed and high stability feeding mechanism for the feeding part.
- 18650 lithium battery sorter adopts servo robotic multi-PCS pick and place structure. So that each cell sorting time is less than 1 second.
- Sorter's sorting box adopts 5-20 gear structure, with full material alarm function, and the door at the end of the box is convenient for fast material discharge.
- The internal resistance and voltage test results of the battery sorter are analyzed by computer to generate classification data and generate curve and bar graph at the same time, which is convenient to make intuitive statistics and display of mass production quality. The testing system has a database function, which can query statistics and export the historical testing data.
- It can replace the mold for many different types of batteries, such as 18650,21700,26650,32650,32700.
The principle of lithium battery sorting machine
Lithium battery sorting machine equipment mainly consists of the following parts.
1、Loading bin part
The loading mechanism discharge bin is made of bakelite with a special loading box. Manually, you only need to put the release box on the position of the loading bin, however, the bottom block will be drawn out on the line feeding is very convenient, there will be no jamming phenomenon, through the motor driven rolling slot teeth, in order to roll into the battery transported to the cache material belt.
2、Feeding mechanism
PVC belt is used to convey the battery cores, and the discharge method is one out of two, both sides of the conveyor belt are transported and tested respectively, and the test is carried out synchronously with very high efficiency.
3、Testing conveyor belt pulling mechanism
The conveyor belt mechanism is composed of conveyor belt and blocking mechanism, when the number of proximity sensors is ten. When the number of proximity sensors is ten, the OCV testing and sorting of the battery cells will begin. This OCV testing and sorting structure has two sets respectively on the left and right, so that there is no need to worry about downtime or material jamming.
4、Battery sorting robotic mechanism
It is mainly composed of screw mechanism and cylinder clamping mechanism. When the detection is completed, the robot goes down to suck the battery cells, this suction cell mechanism uses a magnet to suck because 18650 cells with electromagnetic can be sucked, so the robot goes down to suck up 11 cells at one time.
5、Sorting mechanism
After the cells are sucked up by the XY axis screw accurately put into each gear, and then transported out along the sorting belt line, there are 11 sorting belt lines, representing 11 gears of the cells, the cells are put into the material by 11 groups of suction material structure control, when the test cores are which gears to be placed on which belt line, at this time by the cylinder control magnet absorbed by the cores when the magnet is released, the cores will be dropped in which belt line to flow outward along the difference belt.
6、Battery cell receiving and picking up position
Manually take away the cells in the pickup position for receiving cells, receiving cells also do not need to stop the normal production can be, manual receiving cells when the cells come out normally, then the above is the principle of 18650 battery sorting machine test function.
