The to-be-processed battery cell can be conveyed to the battery cell processing device through the feeding guide rail 120, and after being processed by the battery cell processing device, the processed battery cell is automatically sent out from the discharging guide rail 160.

In one embodiment, the flow chart shown in fig. 7 is taken as an example to explain the main program flow of the loading and unloading system.

1. Firstly, system initialization is carried out, data initialization and zero clearing are carried out on non-retentive data, such as a timer and a storage used in a control device, and a motion axis (namely a feeding motion module and a discharging motion module) is initialized and activated.

2. If the value of the input point I1.6 is 1, the movement axis is in a manual mode, and the feeding manipulator or the discharging manipulator can be manually controlled to move at the moment.

3. And judging an initial bit. If the value of I1.6 is 0, the initial position judgment (the initial position of the system is the position set by the positioner in the feeding motion module and the discharging motion module) is carried out, and whether the system is at the original position at the moment is judged by the state of a proximity switch arranged at the original position on the module. If the position is not at the original point, executing a reference point searching subroutine, and completing the reference searching and the original point returning operation through the state of a proximity switch at the original point position.

4. At the moment, whether the materials meet the feeding condition or the discharging condition is judged through the closing times of the photoelectric switch (the feeding sensing device or the discharging sensing device), the feeding condition is met when the photoelectric switch is closed 10 times in an accumulated mode every time, and the manipulator is started to execute the material processing steps.

5. If the material processing process collides with an object or presses the material, the photoelectric switch (the abnormal feeding sensing device or the abnormal discharging sensing device) acts to indicate that the mechanical arm is excessively pressed, an alarm mode needs to be started, the system is automatically closed to operate, the mechanical arm is upwards bounced, the alarm indicator lamp and the buzzer work.

Wherein, the flow chart of the material processing step is shown in fig. 8, and the specific process comprises:

1. when the discharging condition is met, the manipulator descends to the position of the guide rail. When the battery cell meets the requirement of 10 numbers, and the discharging induction device is closed, I0.6 is high level, and when the discharging condition is met, Q0.2 outputs a direction instruction to the X-axis driver, and Q0.1 outputs a set pulse instruction to the X-axis driver, so that the manipulator descends to the guide rail position.

2. The cylinder action of the claw part of the manipulator is controlled by controlling the state of an output point Q1.0-Q1.7 in the PLC, and the electromagnet is driven to finish the core taking and taking actions.

3. After material taking, the manipulator ascends to an initial position, whether the material in the box is full is sensed through a photoelectric switch arranged on the box, the material boxes are sequentially filled according to the sequence of 1, 2 and 3, if the number 1 box is not full, the manipulator moves to the number 1 material box to the left, then the manipulator descends, the manipulator ascends to return to the material taking, 12 layers of materials with different heights are placed according to the number of layers, and the material box is full of 12 layers.

4. After the material is full, the box No. 2 is placed, and after the material is full, the box No. 2 is placed with the box No. 3.

And 5, when all the materials are filled, the system automatically stops, and the system continues to execute after all the empty boxes are replaced.
