Description

Technical Field

[0001] This utility model relates to the field of battery cell production technology, specifically to a centering device and a casing structure. Background Technology

[0002] In the current production process of short-blade batteries, after Mylar coating, the electrode assembly is installed in the casing. The aluminum casing and battery cell are located on both sides of the gantry jaws. The battery cell is clamped by a clamp and assembled with the aluminum casing using a segmented, progressive installation method. The short-blade battery cell is 500-600mm in length. If the alignment between the battery cell and the aluminum casing is poor during installation, they may scrape against each other, causing damage to the Mylar membrane. In severe cases, this can damage the electrode assembly, leading to electrical conductivity issues between the battery cell and the casing, corrosion and leakage of the explosion-proof valve, resulting in battery quality problems. When this happens, a dummy battery cell is used to adjust the alignment of the installed module. This adjustment involves the clamps, gantry, and aluminum casing positioning mechanism, centering on the gantry. The alignment adjustment process is divided into vertical and horizontal adjustments. The existing battery cell and aluminum casing positioning mechanism has many complex parts, requiring adjustments to numerous components during positioning. This makes the adjustment process cumbersome, time-consuming, and significantly impacts the production line. Utility Model Content

[0024] To facilitate understanding of the technical solution of this utility model by those skilled in the art, the technical solution of this utility model will now be further described in conjunction with the accompanying drawings.

[0025] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] In this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically limited.

[0027] See Figure 1 and Figure 2This embodiment discloses a centering device, including a support base 1, a horizontal adjustment component 2, a vertical adjustment component 3, a support member 4, a positioning plate 5, a two-way cylinder 6, and a positioning stop bar 7. Figure 1 The direction of the middle arrow indicates the direction in which the battery cell is inserted into the casing.

[0028] The support base 1 includes a horizontal support plate 11 and a vertical support plate 12. The horizontal support plate 11 is horizontally slidable on the horizontal adjustment assembly 2 perpendicular to the direction of the battery cell entering the casing. The vertical support plate 12 is vertically fixed at the center position of the horizontal support plate 11. The vertical adjustment assembly 3 is disposed on the vertical support plate 12.

[0029] The horizontal adjustment assembly 2 includes a horizontal slide rail 21, a horizontal slider 22, and fixing screws (not shown in the figure). Two sets of parallel horizontal slide rails 21 are arranged perpendicular to the direction of the battery cell entering the casing. Each set of horizontal slide rails 21 is equipped with a horizontal slider 22. The horizontal support plate 11 is fixed on the two sets of horizontal slide rails 21. The fixing screws are set on the horizontal sliders 21 to lock the horizontal sliders 22 onto the horizontal slide rails 21. Specifically, by loosening the fixing screws, the horizontal sliders 22 can move on the horizontal slide rails 21, thereby driving the support base 1 to slide horizontally perpendicular to the direction of the battery cell entering the casing.

[0030] See Figure 3 The vertical adjustment assembly 3 includes a vertical slide rail 31, a vertical slider 32, a fixing block 33, a lifting screw 34, and a connecting block 35. Two sets of parallel vertical slide rails 31 are vertically fixed to one side of the vertical support plate 12. Vertical sliders 32, capable of vertical movement, are provided on the vertical slide rails 31. The support member 4 is fixed to the two sets of vertical sliders, allowing it to move vertically on the vertical support plate 12. The fixing block 33 is fixed to the vertical support plate 12. The lifting screw 34 is rotatably mounted on the fixing block 33. The connecting block 35 is fixed to the support member 4, with the end of the lifting screw 34 furthest from the fixing block 33 threadedly connected to the connecting block 35. By rotating the lifting screw 34, the support member 4, under the vertical limitation of the two sets of vertical slide rails 31, causes the connecting block 35 to move vertically on the lifting screw 34, thereby driving the support member 4 to move vertically on the vertical support plate 12.

[0031] In this embodiment, a through hole 121 is provided on the vertical support plate 12, and the fixing block 33 is fixed on the vertical support plate 12 at the through hole 121. The through hole 121 facilitates the rotation of the lifting screw 34.

[0032] Furthermore, in this embodiment, the vertical support plate 12 and the support member 4 are connected by a connecting plate 8. Specifically, one end of the connecting plate 8 is fixed to the support member 4, and the other end is provided with a vertical oblong hole 81. Multiple threaded holes are provided on the vertical support plate 12. The end of the connecting plate 8 away from the support member 4 is connected to one of the threaded holes on the vertical support plate 12 through the vertical oblong hole 81 by a locking bolt. Through the setting of the connecting plate 8, it is ensured that the support member 4 can be stably fixed on the vertical support plate 12 when there is no vertical movement, thus preventing the support member 4 from moving.

[0033] The positioning plate 5 is fixed on the top of the support member 4. The two ends of the bidirectional cylinder 6 on the positioning plate 5 are respectively provided with positioning bars 7. The positioning bars 7 are arranged parallel to the direction of the battery cell entering the shell. The positioning plate 5 is used to place the battery cell or aluminum shell. The bidirectional cylinder 6 has a self-centering function. Specifically, by driving the bidirectional cylinder 6, the positioning bars 7 at both ends of it clamp or loosen the battery cell or aluminum shell on the positioning plate 5.

[0034] The working principle of the above-mentioned alignment device is as follows: The battery cell or aluminum shell is placed on the positioning plate 5. The bidirectional cylinder 6 is driven, causing the positioning stops 7 at both ends to clamp the battery cell or aluminum shell on the positioning plate 5. Then, by loosening the fixing screws, the horizontal slider 22 moves on the horizontal slide rail 21, causing the support base 1 to slide horizontally to the required position perpendicular to the direction of the battery cell entering the shell. The fixing screws are then tightened, achieving horizontal adjustment of the alignment device. Finally, the locking bolts on the oblong hole 81 are loosened, allowing the connecting plate 8 to align with the vertical... The support plate 12 is separated, and then the lifting screw 34 is rotated. Under the vertical limit of the two sets of vertical slide rails 31, the connecting block 35 moves vertically on the lifting screw 34, thereby driving the support 4 to move vertically on the vertical support plate 12. This in turn drives the battery cell or aluminum shell on the positioning plate 5 to move vertically to the required position. Then, the rotation of the lifting screw 34 is stopped, and the connecting plate 8 is fixed on the vertical support plate 12 by the locking bolt. This realizes the vertical adjustment of the centering device and quickly completes the centering adjustment of the device.

[0035] It should be noted that, for reference Figure 4 In this embodiment, a housing structure is also provided, including two sets of the above-mentioned centering devices and a mold closing assembly 9. A set of centering devices is provided at each end of the mold closing assembly 9. One set of centering devices is used to place the battery cell, and the other set of centering devices is used to place the aluminum shell.

[0036] In summary, this embodiment, through the coordinated arrangement of support base 1, horizontal adjustment component 2, vertical adjustment component 3, and bidirectional cylinder 6, enables rapid centering adjustment of the device, reduces centering adjustment time, and greatly improves the centering efficiency of the subsequent casing module. Furthermore, the centering device has a simple structure; the positioning plate 5 is supported by only a single support base 1, and the positioning plate 5 is changed from multiple support points to a single support point, eliminating the flatness difference problem caused by multiple support points. Additionally, the bidirectional cylinder 6 controls two positioning stops 7, improving positioning consistency and eliminating the centering difference problem caused by multi-point positioning. Ultimately, this ensures the consistency of centering of the battery cell, mold assembly, and aluminum shell during casing insertion, reducing machine damage caused by electrode assembly rubbing against the aluminum shell during actual production.
