[0030] See also Figures 1 to 3 A battery pack auxiliary fixture (10) comprises: a base (100) and a limiting plate (200) detachably arranged on the base (100), wherein the limiting plate (200) is provided with a plurality of limiting through holes (210) arranged in an array, each limiting through hole (210) being used to limit a battery (300), and the limiting plate (200) is provided with first positioning protrusions (220) at both ends along the arrangement direction of the plurality of limiting through holes (210), the first positioning protrusions (220) being used to fix a sticker strip (400), and a second positioning protrusion (230) being provided on one side along the arrangement direction of the plurality of limiting through holes (210), the second positioning protrusion (230) being used to fix a nickel strip (500).

[0031] It should be noted that the existing insulating stickers, label stickers, QR code stickers, etc. are all prepared in the form of a sticker tape (400), and a first positioning hole matching the first positioning protrusion (220) is provided on the sticker tape (400). Stickers (insulating stickers / label stickers / QR code stickers) to be applied are distributed at intervals on different sticker tapes (400), and each sticker to be applied corresponds to a limiting through hole (210). During operation, the batteries (300) are first placed simultaneously or one by one. The sticker is placed in the limiting through hole (210), and then the first positioning hole (410) of the sticker tape (400) is matched and fixed with the first positioning protrusion (220), and each sticker to be pasted is quickly aligned with a battery (300), and then the sticker tape (400) is pressed toward the battery (300), and then the sticker tape (400) is removed from the fixture, so that the sticker to be pasted is transferred from the sticker tape (400) to the battery (300), thereby completing the pasting operation. At the same time, the positive and negative electrode connectors are also prepared in the form of a positive electrode nickel strip (500) and a negative electrode nickel strip (500), respectively. Electrical connectors are arranged at intervals on the nickel strip (500), and each electrical connector matches a battery (300) on a limiting through hole (210), and a second positioning hole is opened on the nickel strip (500). During the packing operation, the second positioning hole (520) of the nickel strip (500) is matched and fixed with the second positioning protrusion (230), and the alignment and bonding of an electrical connector and a battery (300) are quickly completed, and then the welding operation is performed. Among them, the order of loading different sticker strips (400) and nickel strips (500) can be adjusted according to the specific battery (300) structure. The battery pack auxiliary fixture (10) provided by the utility model brings great convenience and efficiency improvement to the battery pack production through its efficient alignment and fixing functions, flexible operation mode, simple operation process, detachable design and wide applicability.

[0032] See also Figures 1 to 3 Furthermore, a receiving groove (110) is provided on the base (100), the shape of the receiving groove (110) matches the limiting plate (200), and the limiting plate (200) is placed in the receiving groove (110).

[0033] It should be noted that the design of the receiving groove (110) ensures that the limit plate (200) can be accurately and quickly placed at the predetermined position, thereby improving positioning accuracy and operating efficiency; at the same time, the limit plate (200) is more stable after being embedded in the receiving groove (110), and is not easily displaced by external forces, thereby ensuring the stability of the production process; further, the design of the receiving groove (110) can make the installation and disassembly of the limit plate (200) more convenient, reduce adjustment time, and improve mold change efficiency.

[0034] See also Figures 1 to 3Furthermore, the limiting plate (200) includes a negative electrode surface and a positive electrode surface, each limiting through hole (210) connects the negative electrode surface and the positive electrode surface, and the first positioning protrusion (220) and the second positioning protrusion (230) are arranged on the negative electrode surface.

[0035] It should be noted that the double-sided design allows the operations on the negative and positive sides to be flexibly adjusted according to production needs. For example, all stickers and electrical connectors can be positioned on the negative side first, and then flipped to the positive side for other operations, or different operations can be performed on both sides at the same time, thereby improving the battery (300) pack efficiency.

[0036] See also Figures 1 to 3 Furthermore, the positive electrode surface is provided with third positioning protrusions (240) at both ends along the arrangement direction of the plurality of limiting through holes (210), and the third positioning protrusions (240) are used to fix the positive terminal sticker material strip (400). A fourth positioning protrusion (250) is provided on one side along the arrangement direction of the plurality of limiting through holes (210), and the fourth positioning protrusion (250) is used to fix the positive electrode nickel strip (500).

[0037] It should be noted that by providing a special positioning protrusion on the positive electrode surface, a clear division of labor for positive and negative electrode operations is achieved. The negative electrode surface and the positive electrode surface are respectively responsible for fixing the corresponding sticker tape (400) and the electrical connection nickel tape (500), making the production process clearer and more efficient, and reducing the incorrect use of the sticker tape (400) and the nickel tape (500) at both ends of the positive and negative electrodes; at the same time, by providing an additional positioning protrusion on the positive electrode surface, the fixture can adapt to more types of battery pack operations, including situations where the positive electrode needs to be covered with special stickers or connected to specific electrical connectors; further, the precise positioning protrusion can ensure that the positive terminal sticker and the electrical connector can be accurately placed in the predetermined position, thereby improving the quality and reliability of the battery (300) product.

[0038] See also Figures 1 to 3 Furthermore, a plurality of avoidance holes (111) are provided at the bottom of the accommodating groove (110), and the plurality of avoidance holes (111) are respectively used to accommodate the first positioning protrusion (220), the second positioning protrusion (230), the third positioning protrusion (240) and the fourth positioning protrusion (250).

[0039] It should be noted that, firstly, by providing the avoidance hole (111) at the bottom of the receiving groove (110), it can be ensured that the positioning protrusion will not interfere with the bottom of the groove when the limiting plate (200) is placed in the receiving groove (110), thereby making the entire fixture structure more compact. Secondly, the design of the avoidance hole (111) can protect the positioning protrusion from unnecessary wear or damage, because these protrusions can be completely embedded in the avoidance hole (111) when the limiting plate (200) is placed in the receiving groove (110). Thirdly, when the limiting plate (200) is placed in the receiving groove (110), the positioning protrusion will naturally fall into the corresponding avoidance hole (111), which can ensure that the position of the positioning protrusion is accurate each time it is placed, thereby improving the positioning accuracy of the fixture. Finally, since the positioning protrusion can be embedded in the avoidance hole (111), the operator does not need to pay extra attention to the position of the positioning protrusion when placing the limiting plate (200), making the operation more convenient.

[0040] See also Figures 1 to 3 Furthermore, the limiting plate (200) is provided with a avoiding groove (260) at a position adjacent to each positioning protrusion.

[0041] It should be noted that the avoidance groove (260) provides additional space for operators, allowing them to insert fingers or tools more easily, thereby conveniently removing the sticker strip (400) or the nickel strip (500). This greatly improves production efficiency, reduces difficulties and inconveniences during operation, and improves overall operating efficiency.

[0042] See also Figures 1 to 3 Furthermore, each limiting through hole (210) is provided with a first avoiding notch (211).

[0043] It should be noted that the connector or sticker on the side wall of the battery (300) may increase the thickness of the battery (300) or change its shape. The design of the first avoidance notch (211) can effectively prevent these protruding parts from interfering with the edge of the limiting through hole (210), ensuring that the battery (300) can be smoothly placed in and taken out. At the same time, the first avoidance notch (211) provides additional space for placing and taking out the battery (300), so that the operator can more easily perform loading and unloading operations without having to adjust the position or angle of the battery (300) too much.

[0044] See also Figures 1 to 3 Furthermore, a receiving hole (212) is provided on the wall of each limiting through hole (210), and a magnetic attraction component is embedded in the receiving hole (212).

[0045] It should be noted that the magnetic suction piece is used to absorb the battery to ensure that the battery is stably placed in the fixture, so as to ensure that the battery will not fall during the flipping process when the limit plate is flipped to operate on the other side of the battery; further, fixing the battery by magnetic suction can greatly improve the convenience and efficiency of operation. The operator does not need to use additional tools or spend too much time to fix the battery. The battery can be quickly fixed in the limit through hole by simply bringing the battery close to the magnetic suction piece.

[0046] See also Figures 1 to 3 Furthermore, a plurality of avoidance grooves (112) are arranged at the bottom of the accommodating groove (110), and the plurality of avoidance grooves (112) are arranged in one-to-one correspondence with the plurality of limiting through holes (210).

[0047] It should be noted that when the electrical connector is designed to protrude from the end face of the battery, if there is not enough space to avoid it, the battery may not be able to be smoothly placed in the fixture or the electrical connector may be squeezed and damaged. The avoidance groove (112) provides the necessary space to ensure that the electrical connector can stretch freely without interfering with the fixture.

[0048] See also Figures 1 to 3 Furthermore, a plurality of second avoidance notches (113) are provided on the groove wall of the accommodating groove (110).

[0049] It should be noted that the second avoidance notches (113) are of different sizes and are respectively arranged on the four groove walls of the receiving groove (110). Since the nickel strip (500) or the sticker strip (400) may extend to the edge of the limiting plate (200), the second avoidance notches (113) can effectively prevent these materials from interfering with the wall of the receiving groove (110), thereby ensuring smooth operation. The second avoidance notches (113) provide space for the operator's hands or tools to enter, so that the limiting plate (200) can be more easily put in or taken out of the receiving groove (110), thereby improving the convenience of operation.

[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
