Description

Technical Field

[0001] This utility model relates to the technical field of energy storage battery module production equipment, and in particular to an energy storage battery module assembly positioning fixture. Background Technology

[0002] With the rapid development of the new energy industry, energy storage technology, as its key support, has been widely used. Energy storage battery modules are the core unit of energy storage systems, and their assembly quality is directly related to the safety, stability and service life of the entire system. In the automated or semi-automated assembly production line of energy storage battery modules, in order to ensure the accuracy of subsequent welding, fastening and other processes, positioning fixtures are usually used to accurately position and firmly clamp the battery modules.

[0003] However, existing positioning fixtures are often designed for specific battery module specifications, and their structures are usually integrated or fixed. With the diversification of energy storage application scenarios, the size and specifications of energy storage battery modules are also showing a trend of diversification. When the production line needs to switch to produce battery modules of different specifications, such special fixtures are not compatible and must be replaced as a whole or undergo large-scale complex adjustments. This not only greatly increases the equipment procurement costs of enterprises, but also leads to low production efficiency due to frequent line change operations, making it difficult to adapt to the needs of flexible and multi-variety production.

[0004] In addition, although some existing fixtures have certain adjustment capabilities, their clamping process mostly relies on manual operation or simple mechanical limits. This leads to unstable clamping force or insufficient positioning accuracy. In the automated assembly process, even a small positioning deviation may cause the failure of subsequent robotic arm gripping, welding and other processes, thereby affecting product quality and production yield. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an energy storage battery module assembly and positioning fixture, which aims to improve the problems of poor fixture compatibility and inability to adapt to different specifications of energy storage battery modules in the prior art, resulting in high line replacement costs and low efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an energy storage battery module assembly positioning fixture, comprising: a support frame, a positioning mechanism, and a clamping mechanism; The core of the positioning mechanism is a replaceable positioning plate and a clamping and releasing mechanism for fixing it. The clamping mechanism has a positioning platform with a guide groove, a slide that can slide within the groove, and an electric motor for driving the slide; the positioning mechanism and the clamping mechanism are both fixedly connected to the support frame.

[0007] Preferably, the clamping release mechanism includes a positioning frame rotatable about a pivot, a top plate for clamping the positioning plate, and a spring that applies elastic force to the top plate.

[0008] Preferably, the bottom of the positioning frame is provided with a limiting plate, which is connected to the top plate for transmitting the lifting action generated by rotation.

[0009] Preferably, the positioning mechanism further includes a side plate and a fixed plate, wherein the positioning plate is accommodated between the side plate and the fixed plate to achieve lateral limiting.

[0010] Preferably, the upper surface of the positioning plate has a positioning groove for preliminary contour positioning of the energy storage battery module.

[0011] Preferably, a slider is fixedly connected to the bottom of the slide table, and the shape and size of the slider are adapted to the limiting groove to form a sliding fit.

[0012] Preferably, the clamping mechanism further includes a transmission rod connected between the electric motor and the slide table for transmitting linear driving force.

[0013] Preferably, the clamping mechanism further includes an output plate, which is connected between the electric motor and the transmission rod, for converting the rotational motion of the motor into the extension and retraction motion of the transmission rod.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting a quick-replaceable positioning plate and cooperating with a clamping and releasing mechanism consisting of a positioning frame, spring and top plate, the problem of existing fixtures having a single structure, poor compatibility and inability to adapt to different specifications of battery modules is solved, thus achieving the beneficial effects of improving equipment versatility and reducing production line changeover costs and time.

[0015] 2. In this utility model, by setting a slide table driven by an electric motor and using the sliding cooperation between the slider and the limiting groove for guidance, the problems of inaccurate positioning, uneven clamping force, and low efficiency that may exist in traditional manual clamping or positioning methods are solved. The technical effects of automating and accurately clamping battery modules, ensuring stable and reliable positioning reference, and improving assembly accuracy are achieved.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-4 The present invention provides an embodiment of an energy storage battery module assembly and positioning fixture, including a support frame 1, and a positioning mechanism 3 and a clamping mechanism 2 fixedly connected to the support frame 1. The support frame 1 serves as the mounting base of the overall equipment, providing a stable mounting platform for the positioning mechanism 3 and the clamping mechanism 2. The positioning mechanism 3 includes a replaceable positioning plate 301 and a pressing and releasing mechanism for detachably fixing the positioning plate 301, which is used to adapt to and carry energy storage battery modules of different specifications. The clamping mechanism 2 includes an electric motor 202 for providing power and a slide table 205 for clamping the battery module. The slide table 205 moves under the drive of the electric motor 202, thereby completing the automatic clamping and positioning of the battery module. The clamping and releasing mechanism includes a positioning frame 306 rotatably connected to the support frame 1 around a pivot 305, a top plate 308 vertically movable, and a spring 309 disposed above the top plate 308. A limiting plate 307 is fixedly connected to the bottom of the positioning frame 306. The top plate 308 slidably passes through a portion of the support frame 1 and contacts the upper surface of the limiting plate 307. The two ends of the spring 309 abut against the top plate 308 and the support frame 1, respectively. Its function is to achieve rapid clamping and release of the positioning plate 301 through lever transmission and elastic force.

[0020] The positioning mechanism 3 also includes a side plate 303 and a fixed plate 304, both of which are fixedly connected to the support frame 1. The positioning plate 301 is accommodated between the side plate 303 and the fixed plate 304. In the assembled state, the positioning frame 306 is in a horizontal position, the spring 309 is in a compressed state and pushes the top plate 308 downward. The bottom surface of the top plate 308 tightly presses against the upper surface of the positioning plate 301, and the positioning plate 301 is firmly fixed between the side plate 303 and the fixed plate 304. Furthermore, the upper surface of the positioning plate 301 is also provided with a positioning groove 302 for preliminary contour positioning of the energy storage battery module. This lever-spring type pressing structure ensures the convenience of the positioning plate 301 replacement operation and the high stability after fixing. The transmission and guiding structure of the clamping mechanism 2 is defined in detail. The clamping mechanism 2 also includes a positioning platform 201 fixedly connected to the support frame 1. The upper surface of the positioning platform 201 is provided with a limiting groove 207 for guiding. The bottom of the slide table 205 is fixedly connected to a slider 206. The slider 206 slides in cooperation with the limiting groove 207. This guide rail type cooperation structure ensures the high stability and accuracy of the slide table 205 during reciprocating motion. As a further preferred option for the drive connection, the clamping mechanism 2 also includes a transmission rod 204 and an output plate 203. The output shaft of the electric motor 202 is fixedly connected to the output plate 203, the output plate 203 is movably connected to one end of the transmission rod 204, and the other end of the transmission rod 204 is movably connected to the slide table 205. Through this transmission assembly composed of the output plate 203 and the transmission rod 204, the power output by the electric motor 202 can be smoothly transmitted to the slide table 205, driving it to move smoothly along the direction of the limiting groove 207.

[0021] Working principle: When it is necessary to replace the battery module to adapt to different specifications, rotate the positioning frame 306. The positioning frame 306 rotates upward around the rotating shaft 305. The limiting plate 307 at the bottom drives the top plate 308 to move upward. During this process, the spring 309 is stretched and deformed, thereby releasing the pressing force of the top plate 308 on the old positioning plate 301. At this time, the old positioning plate 301 can be taken out from between the side plate 303 and the fixing plate 304 and replaced with a new positioning plate 301. Rotate the positioning frame 306 in the opposite direction to reset it. The spring 309 elastically contracts and drives the top plate 308 to press down, firmly fixing the new positioning plate 301. After the battery module to be assembled is placed into the positioning groove 302 of the new positioning plate 301 for initial positioning, the electric motor 202 of the clamping mechanism 2 is started. Its power is transmitted to the transmission rod 204 through the output plate 203. The transmission rod 204 pushes the slide table 205. Due to the precise sliding fit between the slider 206 at the bottom of the slide table 205 and the limiting groove 207 on the positioning table 201, the movement trajectory of the slide table 205 is strictly limited until its side wall is tightly fitted with the battery module, completing the precise clamping. Through the synergistic effect of the quickly replaceable positioning mechanism 3 and the automated clamping mechanism 2, this utility model solves the problems of poor compatibility and low line changing efficiency caused by the fixed clamping structure in the prior art.
