4.1.7 Other requirements:
The probe is a wearing part with a spring. The service life is related to the test frequency. If the test frequency is very high, it is generally recommended that the customer replace the probe within 30 days, and evaluate according to the specific usage. The probe is more convenient and simple, and it only takes 3-5 minutes. At the same time, our company will distribute certain wearing parts to the user company.
4.2 Cell automatic cleaning and dispensing equipment
4.2.1 Equipment introduction:
This machine is a non-standard plasma cleaning and five-plus-warehouse dispensing machine. It adopts belt assembly line transmission operation. The front-end assembly line is manually or robotically fed to the assembly line. The product flows into the rotating structure through the assembly water transmission. The lifting mechanism lifts the product to the set position, and the plasma cleaning head moves through the screw module to clean the surface of the product. After cleaning, the plasma cleaning head moves away, the rotating structure starts, and drives the product to rotate 180 degrees, and the cleaning head moves over to clean the product. On the second side, after cleaning, the battery product drops to the position of the assembly line, and is sent to the back-end assembly line through the assembly line. After the sensor on the back-end assembly line senses the product, the robot drives the five warehouse glue supply device to dispense the product. It will be sent out after the glue is applied. This equipment sets the program. After starting, it will automatically clean the first side, rotate 180 degrees and turn it over, clean the second side, and dispense glue according to the pre-programmed program, thus saving a lot of labor costs.

4.3 Stack extrusion machine
Extrusion tooling operation instructions
Push the stacking fixture to the stacking position (Figure 2), put down the rotary plunger, and fix the stacking fixture; put the glued cells into the stacking fixture limit slot in order of groups and arrange them neatly. Use your hands to moderately squeeze, place the glued end plate, moderately squeeze, and complete the stack; pull up the rotary plunger, push the stacking fixture to the squeezing position (Figure 2 Station 1 state), and lower the rotary plunger , Fix the stacking fixture; rotate the corresponding squeeze start switch to squeeze. When the limit piece touches the front limit switch to reach the set size, the motor stops (if the set size is not reached, the squeeze pressure reaches the set value first 4000N, the motor stops rotating, the pressure display interface shows that the current pressure module size is unqualified, adjust the battery cell combination); reach the set size, put on the steel belt, rotate the corresponding pressure relief start switch, and make the hand wheel rotate one circle Turn off the pressure relief switch (one turn of the handwheel here is the length reference unit, assuming the value, the length is actually determined according to the process conditions) to force the steel belt; use a baler to bind the plastic steel belt; rotate the corresponding pressure relief start switch, when After the limit piece touches, the limit switch reaches the far point, and the motor stops; pull up the rotating plunger, push the stacking fixture to the stacking position (Figure 2 station two state), put down the rotating plunger, fix the stacking fixture; take out the electricity The core module is placed in the static zone for standing, completing the entire stacking, squeezing and bundling process.
Switch module operation: loosen the top wire on the sliding nut to make it rotate on the screw rod, rotate the pneumatic switch to make the pointer reach the set size position, and at the same time, the sliding nut needs to be twisted to reach the set position, just right Trigger the front limit switch, measure whether the distance between the two extruded end plates is the same as the set value, lock the sliding nut, and complete the module switching operation.
