Background

The power battery is a power unit in the current new energy automobile. The current common power battery forms mainly comprise a cylindrical battery, a soft package battery and an aluminum shell battery. Aluminum-shell cells are generally shaped with square shell structures, as well as plate-like structures, such as blade cells. The power battery needs to be electrified (battery aging) in the production process; for blade batteries, because the length is longer and the thickness is thinner, the formation equipment needs to adjust the probe position to adapt to the blade batteries with larger size differences. In order to solve the technical problem, horizontal formation equipment is adopted for the formation equipment, so that the height of the formation equipment is reduced, and the formation equipment is convenient for staff to adjust.

Because expansion of the battery cannot be avoided in the process of charging and discharging the battery in the formation process, the battery is restrained by a restraining tray in the charging and discharging process in the industry generally, so that the expansion of the battery is reduced by using external force. However, since the process other than charge and discharge does not require restraining the battery, there is a restraining tray assembly and a restraining process before the formation process, and there is a restraining tray de-restraining and tray removing process after the formation process is completed, and generally the restraining station and the assembly station, the de-restraining station and the tray removing station are not in the same position, so that the restraint blocks cannot circulate along with the restraining trays, manual intervention is required, and the operation cost is increased. To solve this technical problem, chinese patent document publication No. CN219303748U discloses a restraint tray and a chemical conversion device, and specifically discloses a restraint tray comprising: the tray structure comprises an end plate assembly and a pressurizing assembly, wherein the pressurizing assembly is connected with the end plate assembly, channels are arranged at intervals along the front-back direction of the pressurizing assembly, and the channels are configured to accommodate the battery cells; the restraint baffle is configured to be connected with the end plate assembly to enclose and form a first placing station, and is positioned on one side of the pressurizing assembly away from the battery cell, and when the pressurizing assembly is pressurized and restrained, the pressurizing assembly moves along the front-back direction to form a second placing station between the pressurizing assembly and the restraint baffle. The pressurizing assembly is connected with the end plate assembly, the restraining baffle is connected with the end plate assembly and is positioned at one side of the pressurizing assembly far away from the battery core, when the battery core is required to be formed, the restraining tray is positioned, the battery core is placed in the channel, then the pressurizing assembly is pressurized and restrained through the restraining mechanism, the pressurizing assembly moves along the front-back direction to form a second placing station, and at the moment, the restraining block is placed in the second placing station and is removed from the restraining mechanism; when the restraint is required to be released, the restraint tray is positioned at first, the restraint mechanism pressurizes the pressurizing assembly, so that the pressurizing assembly moves to the restraint block along the front-back direction, the restraint block is grasped by the clamping jaw, the restraint releasing mechanism hooks the pressurizing assembly and drives the pressurizing assembly to move to the disassembly state, then the restraint block is placed at the first placing station by the clamping jaw, and the pressurizing assembly stays in the disassembly state through the cooperation of the restraint block and the pressurizing assembly, so that the restraint block moves along with the restraint tray, manual participation is not required, automation is improved, and operation cost is reduced.

However, in the technical solution of the above patent document, when the battery is placed in the formation device, the bottom of the battery is supported on the tray of the formation included angle, and the two ends of the battery are in a free state, and a certain distance exists between the two ends of the battery and the positioning blocks at the two ends of the formation device, so that the battery is placed in the formation fixture, and the position of the battery in the length direction is deviated. The electrodes of the blade battery are positioned at two ends, when the battery is formed, the probe is pushed by the movable platform to contact with the electrodes of the battery for conduction, and the suction nozzle is sealed and attached with the liquid injection port. However, before the probe is connected to the electrode of the battery, the pressing mechanism is required to push the laminate to press the battery, so that the battery is pressed tightly, and therefore the battery cannot be displaced in the length direction. Therefore, when the mobile platform drives each probe to contact with the electrode of the battery and when the suction nozzle is connected with the liquid injection port, partial battery is subjected to overlarge pressure by the probe to crush the electrode, and partial probe has smaller contact force with the electrode, so that the problem of poor contact exists. And the problem that electrolyte overflows during formation because part of the suction nozzles cannot seal the liquid injection port.

In addition, when the battery is placed in the formation equipment, the formation equipment with the horizontal structure can enable the battery to be transversely erected in the formation equipment, and then the liquid injection port of the battery faces to one side of the horizontal. In the formation process, when the gas in the battery is extracted by negative pressure, part of the electrolyte is extracted, and the liquid injection port is horizontally arranged, so that a certain amount of electrolyte is extracted, and the performance of the battery after formation may be reduced. And the formation equipment adopts a horizontal structure, so that the occupied area of the equipment can be increased.

The upper end in the frame 200 is provided with a first guiding component 210, the lower end is provided with a second guiding component 220, and the first guiding component 210 and the second guiding component 220 are parallel and horizontally arranged. The upper and lower ends of the plurality of laminated plates 300 are slidably connected to the first guide member 210 and the second guide member 220, respectively, and a battery receiving space 301 is formed between adjacent laminated plates 300 for accommodating a blade battery to be formed. The rear side of each laminate 300 is provided with a stopper 310, a side of the stopper 310 facing the receiving space 301 has a supporting surface 311 for supporting a side of the battery, and the supporting surface 311 is disposed obliquely to the vertical plane. Thus allowing the battery to be placed obliquely when the battery is disposed in the accommodation space 301 and is attached to the support surface 311. The same side of each set of laminates 300 is provided with a first electrical connection assembly 400 and a second electrical connection assembly 500. The first power receiving assembly 400 is disposed at the lower end of the laminated board 300, and the first power receiving assembly 400 includes a first power receiving post 410 for connecting with a post at the bottom side of the battery; the second power receiving assembly 500 is disposed at an upper end of the laminate 300, and the second power receiving assembly 500 includes a top plate 510, a second power receiving column 520, and a suction nozzle 530.
