Examples

As shown in fig. 1 to fig. 6, an embodiment of the first aspect of the present application provides a formation fixture 100, which can effectively improve the formation efficiency of a circular battery cell 200. The detailed structure of the formation jig 100 will be described in detail below.

As shown in fig. 1, the formation jig 100 includes a base 10, a probe assembly 20, and a stopper mechanism 30. The upper surface of the base 10 is provided with a positioning groove 11 for accommodating the circular battery cell 200. The probe assembly 20 includes a first probe 21 and a second probe 22 for electrical connection with the positive electrode and the negative electrode of the circular battery cell 200 located in the positioning groove 11, respectively. The spacing mechanism 30 is attached to the base 10, the spacing mechanism 30 having an open state and a closed state. When the limiting mechanism 30 is in an open state, the circular battery cell 200 can enter the positioning groove 11 from the top of the positioning groove 11; when the limiting mechanism 30 is in the closed state, the limiting mechanism 30 limits the circular battery cell 200 accommodated in the positioning groove 11.

When the formation process is performed on the circular battery cell 200, the limiting mechanism 30 may be in an open state, and at this time, the circular battery cell 200 may be placed in the positioning groove 11 to accurately position the circular battery cell 200; subsequently, the limiting mechanism 30 may be in a closed state, and the limiting mechanism 30 limits the circular battery cell 200 in the positioning groove 11, so as to prevent the circular battery cell 200 from separating from the positioning groove 11 from the top of the positioning groove 11; after the first probe 21 and the second probe 22 are respectively electrically connected to the positive electrode and the negative electrode of the circular battery cell 200, the first probe 21 and the second probe 22 are electrified to implement formation of the accurately positioned circular battery cell 200. After the formation of the circular battery cell 200 is completed, the limiting mechanism 30 may be opened again to take out the circular battery cell 200 from the positioning groove 11. The formation clamp 100 with the structure is simple in structure, can accurately position the circular battery cell 200, and improves formation efficiency.

It should be noted that, the number of the positioning grooves 11 on the base 10 may be one or more (two, three, four, etc.), and similarly, the number of the probe assemblies 20 and the limiting mechanisms 30 may also be one or more (two, three, four, etc.), and one positioning groove 11 is correspondingly provided with one probe assembly 20 and one limiting mechanism 30. In addition, the number of the first probes 21 for electrically connecting with the positive electrode of the circular battery cell 200 in each probe assembly 20 may be one or more (two, three, four, etc.); the second probe 22 in each probe assembly 20 for electrical connection with the negative electrode of the circular battery cell 200 may be one or more (two, three, four, etc.).

Illustratively, the base 10 is provided with two positioning grooves 11. The positioning groove 11 is a circular blind hole formed in the upper surface of the base 10, and the inner diameter of the positioning groove 11 is matched with the diameter of the circular battery cell 200 to be formed.

Optionally, the base 10 includes a first connecting seat 12, a positioning seat 13 and a second connecting seat 14, and the first connecting seat 12 and the second connecting seat 14 are detachably connected to two sides of the positioning seat 13, respectively. The positioning groove 11 is disposed on the upper surface of the positioning seat 13, and the limiting mechanism 30 is connected to the first connecting seat 12 and the second connecting seat 14.

Because the first connecting seat 12 and the second connecting seat 14 are both detachably connected to the positioning seat 13, the positioning seat 13 can be conveniently replaced to adapt to the circular battery cells 200 with different sizes. In the actual forming process, when the radial dimension of the circular battery cell 200 changes, the positioning seat 13 may be replaced, so that the new positioning groove 11 on the positioning seat 13 can position the circular battery cell 200 after the radial dimension changes.

Illustratively, the first connecting seat 12, the positioning seat 13 and the second connecting seat 14 are all block-shaped structures. The first connecting seat 12 and the second connecting seat 14 are connected with the positioning seat 13 through screws. The upper surface of the first connecting seat 12 is coplanar with the upper surface of the second connecting seat 14, and the upper surface of the first connecting seat 12 is higher than the upper surface of the positioning seat 13. The upper surfaces of the first connecting seat 12, the positioning seat 13 and the second connecting seat 14 together form an upper surface of the base 10.

In other embodiments, the base 10 may have other structures, for example, the base 10 may have an integral plate-like structure.

In this embodiment, the first probe 21 and the second probe 22 are both disposed on the limiting mechanism 30, and when the limiting mechanism 30 is switched between the open state and the closed state, the limiting mechanism 30 can drive the first probe 21 and the second probe 22 to move. That is, during the process of switching the position limiting mechanism 30 from the open state to the closed state, and during the process of switching the position limiting mechanism 30 from the closed state to the open state, the position limiting mechanism 30 drives the first probe 21 and the second probe 22 to move.

When the limiting mechanism 30 is in the closed state, the first probe 21 and the second probe 22 are electrically connected to the positive electrode and the negative electrode of the circular battery cell 200, respectively. That is to say, after the circular battery cell 200 is placed in the positioning groove 11, when the limiting mechanism 30 is switched from the open state to the closed state, the first probe 21 and the second probe 22 are just electrically connected with the positive electrode of the circular battery cell 200 and the negative electrode of the circular battery cell 200 respectively under the action of the limiting mechanism 30, and the limiting mechanism 30 limits the circular battery cell 200 in the positioning groove 11 and completes the butt joint of the first probe 21 and the second probe 22 with the positive electrode and the negative electrode of the circular battery cell 200 respectively, thereby further improving the formation efficiency.

As can be seen from the above, the limiting mechanism 30 has two functions, namely, the limiting mechanism limits the circular battery cell 200 in the positioning groove 11, and drives the first probe 21 and the second probe 22 to move, so that the first probe 21 and the second probe 22 are respectively in butt joint with the positive electrode and the negative electrode of the circular battery cell 200.

In other embodiments, the first probe 21 and the second probe 22 may be arranged in other manners, for example, the first probe 21 is movably disposed on the first connecting base 12, and the first connecting base 12 is provided with a slide hole for moving the first probe 21; the second probe 22 is movably disposed on the second connection seat 14, and a sliding hole for the second probe 22 to move is disposed on the second connection seat 14. After the circular battery cell 200 is placed in the positioning groove 11 and limited by the limiting mechanism 30, the first probe 21 and the second probe 22 may be moved to make the first probe 21 and the second probe 22 respectively and electrically butt-joint with the positive electrode and the negative electrode of the circular battery cell 200, so as to realize the electrical connection between the first probe 21 and the positive electrode of the circular battery cell 200, and the electrical connection between the second probe 22 and the negative electrode of the circular battery cell 200.

Optionally, the limiting mechanism 30 includes a first movable member 31 and a second movable member 32 disposed opposite to each other on the base 10. The first movable member 31 is movably disposed on the base 10, the first probe 21 is mounted on the first movable member 31, and the first movable member 31 has a first limiting portion 311; the second movable member 32 is movably disposed on the base 10, the second probe 22 is mounted on the second movable member 32, and the second movable member 32 has a second limiting portion 321. Under the condition that the limiting mechanism 30 is in the open state, the first movable member 31 and the second movable member 32 move towards each other, so that the first limiting portion 311 and the second limiting portion 321 are located above the circular battery cell 200 accommodated in the positioning groove 11, so as to switch the limiting mechanism 30 to the closed state.

The first movable member 31 and the second movable member 32 are movably disposed on the base 10, and the first limiting portion 311 and the second limiting portion 321 are located above the circular battery cell 200 by moving the first movable member 31 and the second movable member 32 in a direction approaching each other, so as to limit the circular battery cell 200. Of course, when the limiting mechanism 30 is switched from the closed state to the open state, the first movable member 31 and the second movable member 32 may be moved in directions away from each other, so as to take out or put in the circular battery cell 200. Furthermore, since the first probe 21 is mounted to the first movable member 31, during the movement of the first movable member 31 relative to the base 10, the first probe 21 will move together with the first movable member 31; because the second probe 22 is mounted to the second moveable member 32, during movement of the second moveable member 32 relative to the base 10, the second probe 22 will follow the second moveable member 32. That is, when the first movable member 31 and the second movable member 32 approach each other, the first probe 21 and the second probe 22 also approach each other; when the first movable member 31 and the second movable member 32 are away from each other, the first probe 21 and the second probe 22 are also away from each other.

The first movable member 31 is movably disposed on the first connecting seat 12 of the base 10, and the second movable member 32 is movably disposed on the second connecting seat 14 of the base 10. The first limiting portion 311 of the first movable member 31 is disposed opposite to the second limiting portion 321 of the second movable member 32.

In other embodiments, the first movable member 31 and the second movable member 32 may also be connected to the base 10 in other manners, for example, the first movable member 31 and the second movable member 32 are both rotatably connected to the base 10, the first movable member 31 and the second movable member 32 can both rotate around a vertical axis, and the first limiting portion 311 and the second limiting portion 321 can also be located above the circular battery cell 200 by rotating the first movable member 31 and the second movable member 32, so as to limit the circular battery cell 200 in the positioning groove 11, and meanwhile, the first probe 21 can also be butted with the positive electrode of the circular battery cell 200, so that the second probe 22 is butted with the negative electrode of the circular battery cell 200.

Of course, the first movable member 31 and the second movable member 32 can be moved in a variety of ways, and the specific structure of the first movable member 31 and the second movable member 32 movably disposed on the base 10 will be described in detail below.

The second base 322 is movably disposed in the second limiting groove 16 of the base 10, and the second limiting groove 16 can limit the moving range of the second base 322, so as to limit the moving range of the second movable member 32.

The first and second limiting grooves 15 and 16 are rectangular grooves. The first base 312 and the second base 322 are both block-shaped structures, the first limiting portion 311 is a bar-shaped structure fixed at one end of the first base 312, and the second limiting portion 321 is a bar-shaped structure fixed at one end of the second base 322.

Alternatively, as shown in fig. 2, the upper surface of the base 10 is provided with a first guide groove 17 communicating with the first stopper groove 15 and for allowing the first guide portion and the first probe 21 to slide out.

The first guide groove 17 is used for sliding out the first guide part and the first probe 21, so that the first guide part can limit the circular battery cell 200, and the first probe 21 can be butted with the anode of the circular battery cell 200.
