1. Equipment introduction:
This equipment is mainly used for the formation of polymer cells under high temperature and pressure. It mainly has heating and temperature control functions, pressure and pressure control functions, charging and discharging and data communication functions.
The whole machine consists of 1 set of energy feedback type, 5V20A-64 channel forming cabinet and 2 sets of fixtures. The fixtures are 16 layers of heating and pressing plates and 64
It is composed of constant current source channels. Each heating plate can be placed with 2 batteries diagonally. The fixture, constant current source and cabinet equipment are integrated.
 
2. Equipment composition
This equipment consists of four parts: temperature control system, pressure control system, forming cabinet system and fixture mechanism.
2.1 Temperature control system
(1) The glass fiber heating plate is attached to the surface of the aluminum plate;
(2) Independent temperature control of each heating plate;
(3) Touch screen + PLC integrated intelligent control;
(4) After the battery is formed, it is cooled naturally;
(5) Over-temperature alarm function.
 
2.2 Pressure control system
(1) It is vertically stacked and pressurized by 16 layers of aluminum sheets covered with insulating paper;
(2) PID pressure output precise control;
(3) The barometer displays the current air pressure.
 
2.3 Formation cabinet system
(1) Charge-discharge and over-charge and over-discharge protection functions
(2) Data network storage function
(3) Voltage detection and sorting function
(4) Smoke alarm function
 
2.4 Fixture and chassis mechanism
(1) Reliable docking function between positive and negative ears and contacts;
(2) Insulation protection of heating plate;
(3) The case cover can be quickly disassembled without tools;
 
2.5 Equipment advantages
1. The thickness of the battery is in the range of 4-10mm, and there is no need to replace the tab pressure block;
2. Nickel-plated copper contacts are used for corrosion resistance.
 
2.6 Equipment operation process:
Turn on the power → manually open the cabinet door → put the battery in the fixture → set the fixture parameters → lower the fixture and send it → remove the battery manually after the fixture ends

4. Technical indicators
4.1 The main performance of the fixture mechanism
4.1.1 The main components of the heating plate: the bottom surface of the aluminum plate is laminated with a glass fiber heating plate, the top surface is laminated with a 1mm thick insulating plate, and the whole is covered with glossy business card paper.
4.1.2 Working mode: the cylinder is driven from top to bottom, the battery is placed in a fixed position between the two layers of heating plates, and the clamping force of the cell is realized through the shrinkage of the clamp, and at the same time, the positive and negative ears of the cell are in contact with the forming cabinet. point of reliable contact.
4.1.3 Pressure setting method: Enter the battery size and the required surface pressure for each section in the touch screen, and the system automatically calculates the required pressure and executes it.
4.1.4 Heating time: Take the room temperature as 25°C for example, ≈10 minutes to heat up to 60°C, and ≈15 minutes to heat up to 75°C.
4.1.5 The contacts used are four-wire gold-plated contacts, which have the advantages of accurate sampling, wear resistance and oxidation resistance of the contacts.
4.1.6 The gap between each layer of clamps is 20mm, and the distance between the pressing block and the contact is 6.3mm, which is convenient for loading and unloading the battery.
