Description

Technical Field

[0001] The utility model relates to the field of battery production, in particular to a tool for detecting the misalignment of a battery coil core welding adapter. Background Art

[0002] During the battery production process, the grouped winding cores are generally connected by ultrasonic welding adapters, the main functions of which are: 1. to guide the flow; 2. to prepare for the welding of the adapter and the top cover in the next process.

[0003] Because the adapter and the top cover are mainly positioned by the core during welding, the welding needs to ensure that the weld mark area is within the embossing of the adapter (to avoid laser high reflection damaging the lens and to ensure welding strength). The embossing area is small, so the relative position between the core and the adapter after welding is completed is very important, which determines whether the next process can be welded normally;

[0004] The existing method for detecting the relative position between the adapter and the winding core is insufficient: because there is a lateral distance between the winding core and the adapter, data collection must be performed visually when measuring with a ruler. This collection method is single and the collection results have large errors. Utility Model Content

[0005] The main purpose of the utility model is to provide a more efficient and accurate tool for detecting the misalignment of the battery core welding adapter.

[0008] The adapter plate mounting seat is arranged on the base and is used to accommodate the adapter plate after welding;

[0009] Two sets of core limit block groups are arranged on the base, respectively located on the left and right sides of the adapter mounting seat, and are used to form a limit fit with the battery cores on both sides when the welded adapter is placed in the adapter mounting seat.

[0010] Furthermore, the adapter plate mounting seat is annular, and the shape and size of the inner cavity of the adapter plate mounting seat are adapted to the welded adapter plate.

[0011] Furthermore, the number and position of the adapter plate mounting seats are matched with the number and position of the adapter plates after welding.

[0012] Furthermore, the adapter plate mounting seat is detachably arranged on the base.

[0013] Furthermore, the winding core limiting block group includes a middle limiting block and two L-shaped side limiting blocks spaced apart and distributed on the front and rear sides of the middle limiting block.

[0014] Furthermore, the two groups of the winding core limiting block groups are symmetrically distributed along the transverse direction of the base, and the two side limiting blocks are symmetrically distributed along the longitudinal direction of the base.

[0015] Furthermore, the tops of the middle limit block and the two side limit blocks are chamfered.

[0016] Furthermore, the side limit block is adjustably arranged on the base.

[0017] Furthermore, the side limit block is adjustably arranged on the base using the following structure: a first connecting column and a second connecting column are provided at the bottom of the side limit block, and the base is provided with more than two first connecting holes for plugging in the first connecting column and more than two second connecting holes for plugging in the second connecting column.

[0018] Furthermore, the first connecting column and the second connecting column are respectively located on the transverse portion and the longitudinal portion of the side limit block, and the first connecting holes and the second connecting holes are arranged in two parallel rows.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0029] See also Figure 1 and Figure 2 .

[0030] The utility model is used for detecting the misalignment of the battery core welding adapter, comprising:

[0031] The base 1 is used to support the welded adapter 10 and the battery roll core 20 on both sides of the adapter 10;

[0032] The adapter plate mounting seat 2 is arranged on the base 1 and is used to accommodate the adapter plate 10 after welding;

[0033] Two groups of core limit block groups 3 are arranged on the base 1, respectively located on the left and right sides of the adapter plate mounting seat 2, and are used to form a limit fit with the battery core 20 on both sides when the welded adapter plate 10 is placed in the adapter plate mounting seat 2.

[0034] The tooling of the utility model can be used to detect whether the battery roll core and the adapter sheet are misaligned after welding. During the detection, the welded adapter sheet and the battery roll cores on both sides of the adapter sheet are placed on the base, the adapter sheet is aligned with the adapter sheet mounting seat, and the battery roll cores on both sides correspond to the two groups of roll core limit block groups. Then the adapter sheet is placed in the adapter sheet mounting seat. Because the adapter sheet after welding is placed in the adapter sheet mounting seat according to the design of the utility model, the two groups of roll core limit block groups respectively form limit cooperation with the battery roll cores on both sides. Therefore, if the battery roll core and the adapter sheet are misaligned in welding, the battery roll core will not be able to cooperate with the roll core limit block group in position and cannot be inserted into the roll core limit block group. Therefore, it is judged that the welding of the battery roll core and the adapter sheet has been misaligned.

[0035] The utility model tooling is used to determine the misalignment of the adapter, thereby reducing the error of visual inspection, being efficient and accurate, and avoiding the flow of defective products to the subsequent process. It can not only play the role of process inspection, but also avoid the generation of batch defects. In addition, when the utility model tooling is used for inspection, the product to be tested is placed in the base, which causes almost no damage to the product, thereby minimizing the situation where good batteries are scrapped due to welding inspection.

[0036] In one embodiment, the adapter plate mounting seat 2 is annular, and the shape and size of the inner cavity of the adapter plate mounting seat 2 are adapted to the welded adapter plate 10. The square ring-shaped adapter plate mounting seat shown in the figure is suitable for square battery winding cores, and the gap between the two can be selected to be about 1 mm. Of course, according to the shape of the winding core, the adapter plate mounting seat can also use other rings.

[0037] In one embodiment, the number and position of the adapter plate mounting seats 2 are adapted to the number and position of the welded adapter plates 10. The number of adapter plates and adapter plate mounting seats shown in the figure is two, distributed along the longitudinal direction of the base. In specific implementation, the number and position of the adapter plate mounting seats can be adjusted according to the number and position of the battery product winding core.

[0038] In one embodiment, the adapter plate mounting seat is detachably arranged on the base. With this design, adapter plate mounting seats of different sizes can be replaced to accommodate adapter plates of different sizes. In a specific implementation, the adapter plate mounting seat and the base can be detachably connected by bolts, or by transitional fit between a connecting column and a connecting hole, and a detachable connection method of direct plugging and unplugging.

[0039] In one embodiment, the core limit block group 3 includes a middle limit block 31 and two L-shaped side limit blocks 32 spaced apart on the front and rear sides of the middle limit block 31. The middle limit block limits the battery core from the middle of the left side or right side, the longitudinal parts of the two side limit blocks also limit the battery core from the left side or right side ends, and the transverse parts of the two side limit blocks limit the battery core from the front and rear sides. In this way, when the adapter is placed in the adapter mounting seat, if the battery core and the adapter are welded and misaligned, the battery core cannot enter between the two side limit blocks. This design has a simple structure and reliable detection effect.

[0040] In one embodiment, the two groups of core limit blocks 3 are symmetrically distributed along the transverse direction of the base 1, and the two side limit blocks 32 are symmetrically distributed along the longitudinal direction of the base 1. This design is suitable for symmetrical products to be inspected. Of course, in specific implementation, the distribution of the above structures can be adjusted according to the products to be inspected.

[0041] In one embodiment, the tops of the middle stopper 31 and the two side stoppers 32 are chamfered. This design can guide the battery core to enter the core stopper group during inspection, thereby reducing damage.

[0042] In one embodiment, the side limit block 32 is adjustably arranged on the base 1. This design can adapt to winding cores of various specifications and can adjust the installation position according to the specifications of the winding core.

[0043] In one embodiment, the side limit block 32 is adjustably arranged on the base 1 using the following structure: a first connecting column 321 and a second connecting column 322 are provided at the bottom of the side limit block 32, and the base 1 is provided with more than two first connecting holes 11 for plugging the first connecting column 321 and more than two second connecting holes 12 for plugging the second connecting column 322. With this design, the side limit block can be detachably installed with adjustable position by inserting the first connecting column and the second connecting column in different first connecting holes and second connecting holes, which is easy to manufacture and convenient to adjust.

[0044] In one embodiment, the first connection column 321 and the second connection column 322 are respectively located on the transverse part and the longitudinal part of the side limit block 32, and the first connection holes 11 and the second connection holes 12 are arranged in two parallel rows. As shown in the figure, the first connection holes and the second connection holes are arranged along the longitudinal direction of the base. With this design, the positions of the two side limit blocks can be adjusted along the longitudinal direction of the base, thereby adjusting the distance between the two side limit blocks in the front and rear directions, and adapting to various specifications of winding cores.

[0045] In one embodiment, the base 1 is a rectangular plate structure. With this design, the structure is light.

[0046] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0047] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
