[0024] In response to the above problems, an embodiment of the present application provides a conversion formation fixture that can avoid the problem of poor contact between the positive electrode probe and the positive electrode post of the battery.

[0025] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0026] Figure 1 It is a structural schematic diagram of the transfer forming fixture shown in an embodiment of the present application.

[0027] See also Figure 1The conversion fixture includes a base 1, an adapter assembly 2, and a probe assembly 3. The base 1 is provided with a mounting slot 11. The length of the mounting slot 11 is greater than the length of the battery. The mounting slot 11 is used to place the battery 4 horizontally. The battery 4 can be inserted into the mounting slot 11 in a horizontal manner. The mounting slot 11 can accommodate a cylindrical battery 4 or a square battery 4. When the battery 4 is inserted into the mounting slot 11, the positive pole of the battery 4 will face the inner side of the mounting slot 11.

[0028] The adapter assembly 2 includes a terminal 21, a wire 22, and a contact 23. Terminal 21 is made of metal and is mounted on the base 1. Terminal 21 is partially recessed into the base 1 and partially exposed on the inner side of the mounting slot 11. Terminal 21 is used to contact the positive terminal of the battery 4. When the battery 4 is placed horizontally in the mounting slot 11, terminal 21 faces the positive terminal of the battery 4, allowing terminal 21 to make contact and establish an electrical connection.

[0029] Wire 22 is located within base 1 and electrically connects to terminal 21 and contact 23. When terminal 21 is electrically connected to the positive electrode, current can flow between terminal 21 and contact 23 through wire 22. Contact 23 is mounted on base 1 and is made of metal. It is located outside mounting slot 11 to prevent battery 4 from obstructing contact 23 when placed horizontally within mounting slot 11. Contact 23 is exposed outside base 1, making it easier for components to contact contact 23. An elastic member 12 is provided on the side of the mounting groove 11 opposite to the terminal 21. The elastic member 12 can be a metal shrapnel, a spring, elastic silicone, elastic rubber, etc. When the battery 4 is inserted into the mounting seat, the elastic member 12 can apply elastic force to the end of the battery 4 facing away from the positive electrode contact, so that the positive electrode contact of the battery 4 is firmly against the terminal 21, ensuring that there is no poor contact between the positive electrode of the battery 4 and the terminal 21. In addition, the elastic member 12 is used to fill the gap between the end of the battery 4 facing away from the positive electrode contact and the mounting groove 11, so that batteries 4 of different lengths can be easily inserted into the mounting groove 11.

[0030] The probe assembly 3 includes a positive probe 31 and a negative probe 32. For a battery 4 whose outer shell is connected to the negative pole, the negative probe 32 is used to contact the outer shell of the battery 4. Since the wire 22 is electrically connected to the contact 23 and the terminal 21 respectively, and the terminal 21 is electrically connected to the positive pole of the battery 4, the positive probe 31 can be electrically connected to the contact 23 by contacting the contact 23, thereby indirectly connecting the positive probe 31 to the positive pole of the battery 4. The positive probe 31 can perform formation charging on the battery 4.

[0031] The present application installs the terminal 21 on the base 1 so that the terminal 21 is exposed in the installation groove 11, and places the battery 4 horizontally in the installation groove 11, and cooperates with the elastic member 12 to apply elastic force to the end of the battery 4 facing away from the positive pole contact, so that the positive pole is firmly against the terminal 21 and electrically connected to the terminal 2, and the positive probe 31 is used to contact the contact piece to charge the battery 4. Compared with the method in which the positive probe 31 contacts the positive pole of the upright battery 4, the positive probe 31 can be effectively prevented from being deviated when contacting the positive pole of the battery 4, and the problem of poor contact between the positive probe 31 and the positive pole of the battery 4 can be avoided. Even if the width or diameter of the battery 4 is small, it will not affect the contact between the positive probe 31 and the positive pole of the battery 4, and it is convenient for the staff to charge the positive pole of the battery 4, thereby improving production efficiency.

[0032] In some embodiments, the contact member 23 is located at the top of the base 1 and is exposed on the upper surface of the base 1. The positive probe 31 can be placed against the contact member 23 from top to bottom, making it easier for personnel to charge and form the battery 4. The upper surface of the contact member 23 is flush with the upper surface of the base 1, making the upper surface of the base 1 more flat. In some embodiments, the contact member 23 can be located on the side of the base 1. When charging and forming the battery 4, the positive probe 31 and the negative probe 32 are located on different sides of the base 1 to prevent accidental contact between the positive probe 31 and the negative probe 32.

[0033] The surface area of ​​the portion of the contact 23 exposed outside the base 1 is larger than the surface area of ​​the positive terminal contact of the battery 4, making it easier for the positive probe 31 to contact and electrically connect with the contact 23, thereby avoiding accidental contact or poor contact between the positive probe 31 and the contact piece.

[0034] Terminal 21 has multiple serrated bumps on one side facing the center of mounting slot 11. Because the surface of the positive electrode contact of battery 4 is easily oxidized by oxygen and forms an oxide film, the provision of multiple bumps on the surface of terminal 21 allows the bumps to scrape away portions of the oxide film when the positive electrode contact contacts terminal 21, thereby allowing electrical conductivity between terminal 21 and the positive electrode, thus preventing poor contact between terminal 21 and the positive electrode. Furthermore, because the multiple serrated bumps are serrated, powder produced by the bumps scraping against the oxide film, even if it gets on the bumps, will not affect the electrical connection between the bumps and the positive electrode of battery 4.

[0035] In some embodiments, one end of the positive probe 31 is provided with a plurality of first protrusions 311, each of which is serrated. Since an oxide film may form on the surface of the contact sheet due to an oxidation reaction, the first protrusions 311 can scrape off the oxide film on the surface of the contact sheet when the positive probe 31 contacts the contact sheet, thereby ensuring that the positive probe 31 can maintain electrical connection with the contact sheet. One end of the negative probe 32 is provided with a plurality of second protrusions 321, each of which is serrated. Since an oxide film may exist on the surface of the battery 4 casing, the second protrusions 321 can scrape off part of the oxide film on the surface of the battery 4 casing when the second protrusions 321 contact the battery 4 casing, thereby ensuring that the negative probe 32 does not lose contact with the battery 4 casing, resulting in a failure in electrical connection.

[0036] In some embodiments, the bottom surface of the mounting groove 11 is a plane, and the mounting groove 11 can be inserted into the square battery 4; in some embodiments, the bottom surface of the mounting groove 11 is an arc surface, and the mounting groove 11 can be inserted into the cylindrical battery 4.

[0037] In some embodiments, the terminal 21 and the contact member 23 are respectively located on opposite sides of the mounting slot 11 , and the wire 22 crosses the mounting slot 11 to prevent the overall structure of the transfer fixture from being too compact.
