Description

Technical Field

[0001] This utility model relates to the field of battery module manufacturing technology, and in particular to a module welding fixture. Background Technology

[0002] In the electronics manufacturing industry, the module welding process is a crucial step in ensuring product performance and consistency. In current production processes, modules are typically placed and welded manually. Since manual positioning relies on experience, it is difficult to achieve high-precision dimensional control, often resulting in problems such as solder joint misalignment and unstable welding positions, leading to poor product consistency and high rework rates.

[0003] Meanwhile, manual welding is inefficient and has limited operating space, which not only increases the labor intensity of workers but also makes it difficult to meet the needs of large-scale production. Although some existing fixtures or tooling can assist in fixation to a certain extent, they generally have shortcomings such as unstable positioning, cumbersome operation, and incompatibility with different module specifications.

[0004] Therefore, there is an urgent need for a welding device with a reasonable structure and convenient operation, which can achieve precise positioning and stable clamping of modules, in order to solve the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to provide a module welding fixture that, through the cooperation of bakelite pad, bakelite pressure plate, positioning pin and locking buckle, achieves three-dimensional precise positioning and stable fixation of the module during the welding process, thereby improving welding quality, consistency and production efficiency.

[0006] This utility model is achieved using the following technical solution: a module welding fixture, characterized in that it includes a bakelite pad, the bakelite pad including a base plate and side walls disposed on both sides of the base plate to define the lateral dimensions of the module, the module being placed on the base plate and located between the side walls; a bakelite pressure plate disposed above the module for pressing and fixing the module; a positioning pin disposed at the end of the base plate of the bakelite pad and cooperating with a positioning hole on the module to define the longitudinal position of the module; and a latch including a fixing frame and a fixing buckle, the fixing frame being fixed on the bakelite pad and the fixing buckle being fixed on the bakelite pressure plate, the fixing frame and the fixing buckle engaging with each other to lock the module when the bakelite pressure plate is pressed down.

[0007] Furthermore, the bakelite pad is made of high-temperature resistant bakelite material to prevent heat conduction during welding from affecting the module positioning.

[0008] Furthermore, the positioning pin is detachably mounted on the bottom end of the bakelite pad to allow for adjustment according to the positioning hole size and position of different modules.

[0009] Furthermore, the fixing frame and the fixing buckle are respectively fixed to the bakelite pad and the bakelite pressure plate by bolts.

[0010] Furthermore, the bakelite pressure plate and the bakelite pad form an opening and closing structure. When the latch is unlocked, the bakelite pressure plate can be flipped open around one end to facilitate the placement and removal of the module.

[0011] Furthermore, the bottom surface of the bakelite pressure plate is provided with a buffer layer to prevent pressure damage to the module surface.

[0012] Furthermore, the latch adopts a quick-locking structure, enabling quick locking and unlocking with one hand.

[0013] The modular welding fixture described in this utility model has the following advantages: The module's position is defined on both sides by the sidewalls of the bakelite pad. Positioning pins engage with the module's positioning holes to ensure stability in the longitudinal and vertical directions, preventing displacement during welding. This multi-directional constraint ensures accurate welding positions and dimensional consistency, thereby improving overall product quality. It also reduces reliance on manual welding position adjustments, minimizes rework due to human error, and significantly improves production efficiency. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Example

[0018] like Figure 1 As shown, this embodiment provides a module welding fixture, including a bakelite pad 1, a bakelite pressure plate 2, a lock 3, a fixing frame 4, a fixing buckle 5, and a positioning pin 6.

[0019] Specifically, the bakelite pad 1 includes a base plate and side walls on both sides of the base plate. The module is placed on the base plate and located between the side walls. The side walls limit the dimensions of the module on both sides, thereby ensuring the stability of the module in the lateral direction. A positioning pin 6 is inserted into the end of the base plate of the bakelite pad 1. The positioning pin 6 cooperates with the positioning hole provided on the module to limit the longitudinal position of the module and ensure that the module remains stable in the same horizontal plane.

[0020] The bakelite pressure plate 2 is positioned above the module to press and secure it before welding, preventing it from shaking during the welding process. The locking mechanism 3 consists of a fixing frame 4 and a fixing buckle 5. The fixing frame 4 is bolted to the bakelite pad 1, and the fixing buckle 5 is bolted to the bakelite pressure plate 2. The fixing frame 4 and the fixing buckle 5 are separate. After the module is placed on the bakelite pad 1 and initially positioned by the positioning pin 6, the operator presses down on the bakelite pressure plate 2, causing the fixing buckle 5 to engage with the fixing frame 4, thus locking the module in place.

[0021] With the above structure, the module welding device provided in this embodiment can quickly achieve precise three-dimensional positioning after the module is placed: the lateral direction is defined by the side wall of the bakelite pad 1, the longitudinal direction is defined by the positioning pin 6 cooperating with the module positioning hole, and the height direction is defined by the bakelite pressure plate 2 pressing down and locking by the latch 3. This device not only effectively improves the accuracy of the module welding position and the dimensional consistency, but also improves the welding efficiency and reduces the error of manual positioning, and has good industrial application value.

[0022] The above embodiments describe the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
