[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

[0030] As mentioned in the background technology, in the physical discharge process, in order to ensure the safety and efficiency of the discharge process, it is usually necessary to use a fixture to fix the aluminum shell battery and connect the electrodes. The fixture not only needs to firmly fix the battery to prevent movement or slipping during the discharge process, but also needs to accurately align the battery electrodes to ensure that the discharge current can pass stably and effectively; however, different types of aluminum shell batteries have differences in size, shape and electrode position. Existing fixtures often lack flexibility and adjustability during operation, and it is difficult to quickly and conveniently replace or adjust to adapt to different types of batteries, which not only affects the work efficiency of the discharge process, but also increases the difficulty and cost of operation.

[0034] The tooling fixture provided by the utility model can fully contact the positive and negative electrodes of retired aluminum shell batteries of different types through the two probe plates (302) provided, and at the same time, the pressurized space can be controlled by the stroke of the driving part, so as to achieve compatibility with most retired aluminum shell batteries with tabs on the same side, and can handle aluminum shell batteries of different specifications and sizes. This improvement not only reduces the dependence on specific fixtures and reduces the frequency of fixture replacement, but also improves the flexibility of the discharge process, so that there is no need to replace the fixture when processing multiple types of batteries, thereby significantly improving work efficiency, and being able to accurately connect electrodes at different positions to ensure that the discharge current can pass smoothly.

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

A relay and a circuit board are also arranged in the support seat (1) to control the aluminum shell battery to connect and disconnect the discharge circuit, adjust the discharge current, and adjust the state of the discharge unit.

[0039] Further, such as Figure 1-Figure 4 As shown, a first insulating plate (301) is fixedly connected between the two probe boards (302), and a wire interface (305) is fixedly connected to the top of the two probe boards (302), and the wire interface (305) is used to connect to the discharge device, that is, the connection between the probe board (302) and the discharge device can be achieved through the wire and the wire interface (305).

[0040] Further, such as Figure 5 As shown, a temperature probe (303) and a voltage probe (304) are arranged in the probe plate (302). The temperature probe (303) is used to detect the temperature and voltage during discharge. The utility model has voltage and temperature monitoring functions, and can monitor the temperature of the probe plate (302) and the battery voltage in real time. When the temperature is higher than the set value, the power is automatically cut off and an alarm is sounded. At the same time, except for the probe plate (302), the other parts in contact with the retired aluminum shell battery are insulated to prevent short circuit.

[0041] Further, such as Figure 1 and Figure 2As shown, a silicone pad (4) is also provided above the support seat (1) and is located between the first insulating plate (301) and the pressure plate (202). The silicone pad (4) is used to support the battery. The silicone pad (4) can make up for the height difference caused by the uneven positive and negative ears of the retired aluminum shell battery, thereby achieving compatibility with retired aluminum shell batteries in different states.

At this time, the positive and negative electrodes of the aluminum shell battery are in contact with the two probe plates (30 2) respectively, and the aluminum shell battery is discharged to the discharge device through the probe plate (302) and the wire.

[0045] Embodiment 3 further optimizes the fixture provided in Embodiment 1. Specifically, Figure 1 and Figure 3 As shown, the bottom of the silicone soft pad (4) is connected to a support plate (401), a second cylinder (402) is installed in the support seat (1), a piston rod of the second cylinder (402) passes through the support seat (1) and is fixedly connected to the support plate (401), and the second cylinder (402) can push the silicone soft pad (4) to move up and down through the support plate (401), so as to adjust the height of the silicone soft pad (4) according to the actual situation of the aluminum shell battery

[0046] Further, such as Figure 1 As shown, both sides of the bottom of the pressure plate (202) are fixedly connected with a slide seat (205), and a guide rail (204) is installed between the slide seat (205) and the support seat (1). The guide rail (204) and the slide seat (205) cooperate with each other to support and limit the pressure plate (202), thereby improving the stability of the horizontal movement of the pressure plate (202).

[0047] Example 4 further optimizes the fixture provided in Example 3. Specifically, Figure 1 , Figure 2 and Figure 4 As shown, a support buffer mechanism is provided between the support seat (1) and the first insulating plate (301), and the support buffer mechanism is used to support and buffer the first insulating plate (301), so as to buffer the probe plate (302) and reduce the situation where the probe plate (302) is damaged due to excessive force when clamping the aluminum shell battery.

[0048] Further, such as Figure 4 As shown, the support buffer mechanism includes a second fixed seat (5) fixedly mounted on the top of the support seat (1), a plurality of connecting rods (501) are inserted and connected on the second fixed seat (5), a second insulating plate (502) is fixedly connected between one ends of the plurality of connecting rods (501), the second insulating plate (502) is fixedly connected to the first insulating plate (301), and the second fixed seat (5), the connecting rods (501) and the second insulating plate (502) cooperate with each other to support the first insulating plate (301) and the probe plate (302).

[0050] The use process of the fixture provided by the utility model is as follows:

[0051] The aluminum shell battery is placed on the top of the silicone soft pad (4), and the second cylinder (402) pushes the silicone soft pad (4) to rise and fall through the support plate (401). The height of the aluminum shell battery is adjusted according to actual conditions so that the positive and negative pressures of the aluminum shell battery correspond to the two probe plates (302). The first cylinder (206) pushes the pressure plate (202) to move toward the first insulating plate (301), so that the probe plate (302) and the pressure plate (202) clamp and fix the aluminum shell battery, so that the positive and negative electrodes of the aluminum shell battery are in contact with the two probe plates (302) respectively. When the pressure plate (202) pushes the aluminum shell battery to contact the probe plate (302), the buffer spring (503) is squeezed to generate a force to buffer the probe plate (302).
