[0033] Working principle: When this device is in use, the stacker crane first places the pallet onto the pallet plate assembly 23. The pallet is inserted into the positioning pin 237. The two sets of oblique angle photoelectric sensor assemblies 238 detect no abnormalities, indicating that the pallet is placed in the positioning pin 237. The lower cylinder 226 drives the lower needle plate assembly 22 to rise. After the lower needle plate 221 rises, the upper cylinder 246 drives the upper needle plate assembly 24 to fall. Physical limitation is achieved through the lower needle plate limiting post 227 in the lower needle plate assembly 22 and the cylinder connecting rod 248 in the upper needle plate assembly 24. The probe 24410 contacts... The battery surface is compressed to a certain extent for the charging and discharging process. It is mounted on the FR4 pin board 2445 via the pin board PCBA24411. The pin sleeve 2449 is inserted through the FR4 pin board 2445 and soldered onto the pin board PCBA24411. The probe 24410 is inserted into the pin sleeve 2449 for easy maintenance. The top single channel has two probes 24410 corresponding to current and voltage. It is connected to the connector on the external adapter board PCBA24413 via a pin-type adapter board PCBA24412. The overall design is neat and tidy. With multiple wire harnesses leading out, the heat dissipation effect will be better when combined with the heat dissipation holes on the FR4 pin plate 2445 and the top fan assembly 2411. The entire upper pin plate drawer assembly 244 can be pulled out via the driven wheel 2447 to maintain the innermost probe 24410. Because the compression force below is greater than that of the upper probe 24410, the battery is suspended after compression of both pins. The tray assembly 23 only bears the weight of the tray, resulting in minimal deformation. It is fixed by inserting a stamped guide rail on the frame, where the current and voltage are connected... The connector is connected to the connectors on the upper needle plate drawer assembly 244 and the lower needle plate drawer assembly 224. The power supply copper busbar is connected to the inverter power supply 33, and the communication connector is connected to the main control board 35. Since the DC-DC module 312 generates a lot of heat during operation, a row of fans 36 is added behind the drive tray 31 for heat dissipation. The number of channels is increased from 256 to 576 through the needle sleeve 2449 and probe 24410. The production efficiency is high, the overall cost is low compared to the number of channels of multiple devices, and the detection consistency and stability are high.
