On the basis of the structure, when the cell positioning device is used, the cell frame 4 is placed in a positioning space, a positioning piece is matched with the cell frame 4, a positioning pin 01 corresponds to a positioning hole on the cell frame 4, a position sensor 02 on the positioning piece senses the position of the cell frame 4, after the balance of the cell frame 4 is detected, a position signal is transmitted to a controller, the controller controls the cell frame 4 to move, then in the moving process of the cell frame 4, a micro-motion sensor 03 also detects whether the cell frame 4 changes in the moving process, so that the cell frame 4 is kept at the original position of the positioning space, the controller controls the cell frame 4 to move, and the position sensor 02 and the micro-motion sensor 03 ensure the accurate position of the cell frame 4, so that the cells can be aligned with the probes 240.

Before the probe 240 is electrically connected, a plurality of electric cores are orderly placed in the electric core frame 4 and then conveyed to the sorting cavity 11, and as the electric cores of the electric core frame 4 placed on the sorting cavity 11 are not aligned with the probe 240, the electric core frame 4 and the positions of the electric cores are required to be manually adjusted for a plurality of times, so that the working efficiency is lower.

By arranging the position sensor 02, the accurate position of the electric core frame 4 when being placed in the positioning space can be effectively ensured, the electric core frame 4 can be aligned with the mounting frame 21, the electric core in the electric core frame 4 can correspond to each probe 240 of the probe group 24, and the position sensor 02 can transmit a position signal to the controller only when the electric core frame 4 can be accurately mounted in the positioning space and the position sensor 02 can sense that the electric core frame 4 is arranged at the corresponding position; when the controller controls the electric core frame 4 to move close to the mounting frame 21, the micro-motion sensor 03 further detects the accurate position of the electric core frame 4 in the moving process to confirm whether the electric core frame 4 moves relative to the positioning space in the moving process, so as to ensure that the electric core can be accurately electrically connected with the probe 240 after the electric core frame 4 approaches to the mounting frame 21, and the capacity division of the electric core can be smoothly realized.

When the battery cell positioning device is used, when an RGV (rail shuttle trolley) automatically places a battery cell into a positioning space, under the action of a positioning piece and a position sensor 02, the mounting and guiding positioning tolerance of the battery cell is within +/-10 mm, the positioning precision is within +/-2 mm of a specified position, and in the process that the battery cell frame 4 is close to the mounting frame 21 and is pressed, the positioning pin 01 precision is within +/-0.5 mm, so that the battery cell can be aligned to the probe 240 when being close to the mounting frame 21, and is accurately electrically connected with the probe 240, and the capacity division of the battery cell can be smoothly realized.

In addition, the positioning pin 01 has a diameter of 15.3mm and a position precision of + -0.2 mm, the positioning hole of the electric core frame 4 has a hole diameter of 16mm, the positioning holes are arranged on the opposite corners of the electric core frame 4, four positioning holes which are symmetrically arranged on the electric core frame 4 in a rectangular shape with the length and width center line of the electric core frame 4 and correspond to the positioning pin 01, and when the positioning pin 01 is inserted into the positioning holes, the positioning of the electric core frame 4 is realized.

It should be noted that, in the present embodiment, the position sensor 02 is implemented by a travel switch, and the position sensor 02 is disposed at a diagonal angle of the positioning space to detect whether the electric core frame 4 can be balanced and accurate when being installed in the positioning space, however, the position sensor 02 may be implemented by other manners in the prior art, such as a pressure sensor, etc., and may be selected and set according to the needs of the actual situation.

Further, the cell positioning device further comprises a first detector 04 and a second detector 05, and the first detector 04 and the second detector 05 are electrically connected with the controller; the first detector 04 is used for detecting the position of the electric core frame 4 when the controller controls the electric core frame 4 to move upwards; the second detector 05 is used to detect the position of the die frame 4 when the controller controls the die frame 4 to move down.

In the case of example 2,

the battery cell capacity sorting equipment as shown in fig. 1 to 9 comprises a machine body 1 and a cooling component, wherein the machine body 1 is provided with a sorting cavity 11 and a power cavity 12, and a power module is arranged in the power cavity 12; the bottom end of the sorting cavity 11 is provided with a first air port, and the top end of the sorting cavity 11 is provided with a second air port; the top end of the power cavity 12 is provided with a third air port, and the bottom end of the power cavity 12 is provided with a fourth air port; the second air port is communicated with the third air port; the fourth air port is communicated with the first air port; the cooling component is arranged in the machine body 1 and used for reducing the temperature of air flowing through the cooling component and discharging the air through the fourth air port.

On the basis of the above structure, when the battery cell capacity sorting device of the present application is used, the power module is installed in the power cavity 12, and the power module is electrically connected with the probe assembly 2 and the bypass board assembly 3 in the sorting cavity 11 through the wires, so that the power module provides current and voltage for the probe 240 and the bypass board 31 during operation, and the probe 240 and the bypass board 31 are electrically conductive.

In this embodiment, since the power module, the probe 240, the bypass plate 31 and the battery cells all generate heat during the charging and discharging process, the charging and discharging process is affected, so that during the working process, the cooling component also reduces the temperature of the air flowing through the cooling component in the machine body 1, so that the hot air forms cold air, and guides the cold air to be discharged through the fourth air port, the cold air flows from the first air port to the sorting chamber 11 after being discharged through the fourth air port, moves upwards, cools the battery cells, the probe 240, the bypass plate 31 and other parts, then flows back to the power chamber 12 through the second air port and the third air port, flows to the bottom end of the power chamber 12, passes through the power module, cools the battery cells, and then flows to the fourth air port for circulation.

Because the power supply module is arranged in the power supply cavity 12 of the separation cavity 11, the distance between the power supply and the probe 240, the bypass plate 31 and the battery core is small, and the wires connecting the power supply and the probe 240, the bypass plate 31 and the battery core are relatively short, thereby reducing the cost of the wires and the resistance of the wires, reducing the loss of the power supply and improving the charge and discharge efficiency.

The power cavity 12 is provided with a power module, the power module is provided with 5 V.times.120A.times.4 channels, a single power module can realize 120A current, in the charging process, the charging current is adjusted between 120 mA and 120000mA, and the charging voltage is adjusted between 0V and 5V so as to meet different charging requirements. In the adjusting process, the accuracy of the current is 0.05% of the set value and 0.05% of the measuring range, so that the accuracy of the current is guaranteed to be adjusted, and the capacity of the battery cell is accurately divided. In addition, in order to realize the electric energy conversion from the industrial AC380V power supply to DC, a three-phase power supply is needed, and the complete three-phase balanced power taking can be realized under the conditions of any number of layers and columns of the warehouse, and the range of the three-phase unbalanced current is limited in a range less than or equal to 4 percent so as to ensure the normal operation and the accuracy of work.

Besides the production line specially required by cylindrical lines and the like, the actual channel number of one physical module cannot exceed 8 (4 channels of one physical module can be allowed); and the power supply module must not cross the bank.

The power module of the power cavity 12 also has single-channel independent control, when the upper computer software clicks the single-channel issuing function in a right-click mode, the single-channel process step is independently skipped without waiting, current is pulled up, and the like, and the function of running different processes at the same time in each channel of the same library position is achieved. The power supply module also has an energy feedback function, the charging efficiency is more than or equal to 55 percent (battery capacity/power grid consumes electric energy) in the state of containing line loss, and the feedback efficiency is more than or equal to 50 percent (battery discharge capacity/feedback electric energy recorded by the bidirectional intelligent electric meter) in the state of containing line loss.

In addition, the voltage sampling precision of the power supply module is +/-3 mV, and the negative voltage collecting function is achieved; in the purchasing range of the power supply modules, the power supply modules comprise the matched number of power lines, sampling lines and the like of each power supply module.

The power module also has the function of collecting real negative voltage, and endows negative value instead of collecting absolute value, so that the power module has a perfect battery positive-negative reverse connection protection function; besides negative pressure switching, other process step type switching can realize single-channel process step switching, and the pause step in the process of switching the negative pressure is protected according to the shelving protection parameters; the power module also has the function of dynamic constant volume charge and discharge.

In addition, in this embodiment, the cooling component is disposed in the machine body 1, the cooling component reduces the temperature of the air flowing through the cooling component, so that the hot air forms cold air, and the cold air is guided to be discharged from the fourth air port and flows into the sorting cavity 11, and cools the components in the sorting cavity 11, and then when the cold air rises to the top end of the sorting cavity 11, the cold air flows back from the second air port at the top end of the sorting cavity 11 to the third air port at the top end of the power cavity 12, flows into the power cavity 12 through the third air port, so that the power cavity 12 is also filled with the cold air, and cools the power supply.

If there is no cooling component, the components such as the power supply, the probe 240, and the bypass plate 31 continuously pass through the current voltage to cause temperature increase due to the charge and discharge operation, and the normal operation of the charge and discharge operation is affected due to the temperature increase. In this embodiment, the temperature of the power supply, the probe 240, the bypass plate 31 and other parts can be effectively reduced by arranging the cooling component, so that the efficiency of charge and discharge operation can be ensured.

The cooling component has a heat dissipation function, the cooling component dissipates heat, and the air volume of the fan 64 of the cooling component can meet the requirement of the power supply heating calculation meter, namely, the heating of the fan 64 has less influence on other parts in the machine body 1. The wind speeds of the fan 64 and the fan 63 are subjected to negative feedback adjustment through the temperature detector, and when the temperatures of the fan 64 and the fan 63 are too high, the wind speeds are reduced; when the temperature of the fan 64 and the fan 63 is reduced, the wind speed is increased, so as to ensure that the heat generation condition of the fan 64 and the fan 63 cannot influence the normal operation in the machine body 1.

And the fan 64 is arranged at the bottom of the machine body 1, and in the setting process, a certain gap needs to be reserved between the fan 64 and the bottom, so that the fan 64 can effectively take out wind from the bottom of the machine body 1.
