[0050] Below, the embodiments of the present application are described in detail.

[0051] At present, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0052] In the production process of power batteries, a battery welding device is required to weld the conductive sheet and the battery cell to achieve the connection between two adjacent battery cells. The battery welding device generally includes a welding frame, a welding positioning tool installed on the welding frame, and a carrier for carrying the battery located below the welding positioning tool. The welding positioning tool and the carrier are used to clamp and position the battery so as to perform subsequent welding of the conductive sheet.

[0053] During the above clamping and positioning process, the positioning welding parts on the welding positioning tooling are positioned with the poles of the battery cells so that the centers of the poles of the battery cells and the positioning welding parts remain coincident, thereby using the positioning welding parts to press the connecting aluminum sheet of the battery and the poles of the battery cells.

[0054] However, the position of the existing battery welding positioning tool on the welding frame cannot be accurately adjusted, resulting in poor positioning accuracy, affecting the welding quality, and this problem can only be circumvented by replacing the welding positioning tool, which affects the efficiency of positioning welding.

[0055] Therefore, how to improve the positioning accuracy of welding positioning tooling and reduce the frequency of replacing welding positioning tooling is an important issue in battery production and processing.

[0056] In view of this, the present application provides a technical solution, which is equipped with a first adjustment component and a second adjustment component, which can adjust the position of the cover plate in the first direction and the second direction, so that the positioning welding parts on the cover plate can be more quickly aligned with the poles of the battery cell, thereby improving the positioning accuracy and positioning efficiency of the tooling and the battery, reducing the frequency of replacing the tooling, and thus improving the welding efficiency of the battery.

[0057] The following is combined with Figure 1-7 The structure of the battery welding positioning tool provided in the embodiment of the present application is introduced.

[0058] Combined with Figure 1 , Attachment Figure 4 and attached Figure 6 As shown in , an embodiment of the present application provides a battery welding positioning tool 100, including a positioning assembly 10, a first adjustment assembly 20 and a second adjustment assembly 30; the positioning assembly 10 includes a cover plate 11, end plates 12 located at both ends of the cover plate 11 along a first direction X, and a plurality of positioning welding parts 13 installed on a surface of the cover plate 11 at intervals, and the first direction X is the extension direction of the cover plate 11; the first adjustment assembly 20 is respectively connected to the end plate 12 and the cover plate 11, and is used to drive the cover plate 11 to move along the first direction X between the two end plates 12; the second adjustment assembly 30 is installed on the end plate 12 and is used to be connected to the welding frame 200, and the second adjustment assembly 30 is used to drive the end plate 12 and the cover plate 11 to move along the second direction Y, and the second direction Y intersects with the first direction X.

[0059] The positioning assembly 10 of this embodiment is used to press down the battery during welding, and can cooperate with the battery-carrying platform 300 under the welding frame 200 to limit and press the battery, and the multiple positioning welding parts 13 on the positioning assembly 10 are used to press the conductive sheet onto the pole on the battery cell. The functions of the positioning welding parts 13 include laser welding and positioning the conductive sheet. Its structure can be Figure 6 The welding nozzle can be made of copper, aluminum and other metal materials.

[0060] The cover plate 11 of the present embodiment is a plate-shaped member as a whole. The cover plate 11 has an extension direction or a length direction along a first direction X, and a width direction along a second direction Y. The material of the cover plate 11 can be metal such as stainless steel or other non-metals with a certain structural strength (such as polyethylene, polypropylene, etc.), and the material of the end plate 12 can also be the above-mentioned metal or non-metal.

[0061] The first adjustment component 20 of this embodiment can drive the cover plate 11 to move relative to the welding frame 200 in the first direction X, and the second adjustment component 30 can drive the cover plate 11 and the end plate 12 to move as a whole relative to the welding frame 200 in the second direction Y, so that the positioning welding part 13 on the cover plate 11 can be aligned with the pole of the battery cell more quickly, thereby improving the possibility of aligning the center of the positioning welding part 13 with the pole, thereby improving the positioning accuracy and positioning efficiency of the tooling and the battery, thereby improving the welding efficiency of the battery.

[0062] Combined with Figure 1 and attached Figure 2 As shown in , in some examples, optionally, the first adjustment component 20 of this embodiment includes a first linear reciprocating motion mechanism 21, and the first linear reciprocating motion mechanism 21 is respectively connected to the cover plate 11 and the end plate 12, and the linear motion of the first linear reciprocating motion mechanism 21 drives the cover plate 11 to move along the first direction X between the two end plates 12.

[0063] The first linear reciprocating motion mechanism 21 can be understood as a structure that can perform linear motion in two opposite sub-directions along the first direction X, which can be a screw nut structure, a gas rod structure, a hydraulic rod structure, a gear rack structure, etc. The first linear reciprocating motion mechanism 21 can be driven by manpower or electricity or hydraulics. From the perspective of the action principle, the first linear reciprocating motion mechanism 21 may include an active member and a driven member. The action of the active member drives the driven member to perform linear motion. The active member can be a screw / bolt that drives the thread. At this time, the driven member can be a nut structure. The active member can also be a gear, and the driven member is a rack.

[0064] In the present application, the first adjustment component 20 is designed to include a first linear reciprocating motion mechanism 21 , and the cover plate 11 can be adjusted left and right in two opposite sub-directions of the first direction X by utilizing the action of the first linear reciprocating motion mechanism 21 .

[0065] In some examples, optionally, the first linear reciprocating motion mechanism 21 of the present embodiment includes a first adjusting screw 211 and a first connecting member 212. The first adjusting screw 211 can be installed on the end plate 12 and can rotate around its own axis, and it can serve as the aforementioned first active member. The first connecting member 212 is installed on the cover plate 11 and is threadedly connected to the first active member, and it can serve as the aforementioned first driven member. The rotation of the first adjusting screw 211 drives the first connecting member 212 and the cover plate 11 to move along the second direction Y.

[0066] The first adjusting screw 211 of this embodiment is threadedly connected to the first connecting member 212 to form the above-mentioned screw-nut structure. The first connecting member 212 can be understood as a structure that acts as a nut. The operator rotates the first adjusting screw 211 to achieve linear reciprocating motion of the first connecting member 212, thereby driving the cover plate 11 to move in the first direction X. The structure is simple and easy to operate.

[0067] Of course, the first adjusting screw 211 can also be installed on the cover plate 11, and the first connecting member 212 can be installed on the end plate 12 (this embodiment is not shown in the figure). In addition, the first adjusting screw 211 and the first connecting member 212 mentioned above can be replaced by a gear rack structure, a gas rod structure, etc., as long as it can drive the cover plate 11 to move between the two end plates 12 along the first direction X. This embodiment will not list them one by one.

[0068] Combined with the attachment again Figure 1 and attached Figure 2 As shown in, in some examples, optionally, the end plate 12 of this embodiment has an overlapping portion 121 located on the surface of the cover plate 11, and the overlapping portion 121 is provided with a first guide hole 1211 penetrating through itself along a third direction Z, and the third direction Z intersects with the first direction X and the second direction Y respectively; the first connecting member 212 is located in the first guide hole 1211 and can move in the first guide hole 1211 along the first direction X; the first adjusting screw 211 is installed in the overlapping portion 121 and extends into the first guide hole 1211.

[0069] In some examples, optionally, in this embodiment, the third direction Z is perpendicular to the first direction X and the second direction Y respectively, and the first direction X is perpendicular to the second direction Y.

[0070] The size of the overlapping portion 121 of this embodiment along the first direction X can be approximately equal to that of the rest of the end plate 12, and the size of the overlapping portion 121 along the second direction Y can be smaller than that of the rest of the end plate 12. A step-shaped structure is formed between the overlapping portion 121 and the end plate 12, and the end of the cover plate 11 can be located just below the overlapping portion 121, saving space. At the same time, the overlapping portion 121 also facilitates the connection between the end plate 12 and the cover plate 11.

[0071] The size of the first guide hole 1211 of this embodiment along the first direction X is much larger than the size of the first connecting member 212 in the first direction X, and the size of the first guide hole 1211 along the second direction Y is slightly larger than or equal to the size of the first connecting member 212 in the second direction Y, so that the first connecting member 212 of this embodiment can move along the first direction X along the guidance of the first guide hole 1211. At the same time, the first guide hole 1211 is used to accommodate the first connecting member 212 and part of the first adjusting screw 211, so that the volume of the positioning assembly 10 can be further reduced, and the integrity and connection stability between the end plate 12 and the cover plate 11 can be improved to a first extent.

[0072] In some examples, optionally, the end plate 12 of this embodiment is provided with a first locking structure 122, and the first locking structure 122 is used to connect the cover plate 11 and limit the movement of the cover plate 11 along the first direction X.

[0073] After adjusting the position of the cover plate 11 along the first direction X, the adjusted cover plate 11 can be locked by the first locking structure 122 of this embodiment, thereby reducing the possibility of unnecessary displacement of the cover plate 11 after position adjustment and improving the stability of the positioning welding part 13 on the cover plate 11 and the battery after positioning.

[0074] In some examples, optionally, the first locking structure 122 of the present embodiment includes a first sliding hole 1221 and a first locking member 1222 , and the first locking member 1222 is slidably connected to the first sliding hole 1221 and is used for detachable connection with the cover plate 11 .

[0075] The first locking member 1222 of this embodiment can be a screw or a bolt. Accordingly, the cover plate 11 is provided with a first connection hole (not shown in the figure) adapted to the screw or the bolt. When the position of the cover plate 11 along the first direction X is adjusted, the first locking member 1222 of this embodiment is not connected to the first connection hole. After the position of the cover plate 11 is adjusted, the first locking member 1222 in the first sliding hole 1221 can be slid so that the first locking member 1222 is aligned with the first connection hole, thereby completing the locking between the cover plate 11 and the end plate 12 in the first direction X. Therefore, it can be concluded that the sliding of the first locking member 1222 in the first sliding hole 1221 can match the movement of the cover plate 11, so that the first locking member 1222 can be detachably connected to the cover plate 11 at all times.

[0076] The number of the first locking structures 122 in this embodiment can be multiple. For example, each end plate 12 in the figure has eight first locking structures 122 , and the eight locking structures are evenly distributed around the two first adjustment components 20 .

[0077] Combined with the attachment again Figure 1 and attached Figure 3 As shown in, in some examples, optionally, the second adjustment assembly 30 of this embodiment includes a second linear reciprocating motion mechanism 31, which is installed on the end plate 12 and is used to connect the welding frame 200. The linear motion of the second linear reciprocating motion mechanism 31 moves the two end plates 12 and the cover plate 11 along the second direction Y.

[0078] The second linear reciprocating motion mechanism 31 can be understood as a structure that can perform linear motion in two opposite sub-directions along the second direction Y. It is similar in structure and principle to the aforementioned first linear reciprocating motion mechanism 21, and can also be a screw-nut structure, a gas rod structure, a hydraulic rod structure, a gear rack structure, etc. The second linear reciprocating motion mechanism 31 can be driven by manpower or electricity or hydraulics. The second linear reciprocating motion mechanism 31 can also include an active member and a driven member. The action of the active member drives the driven member to perform linear motion. The active member can be a screw / bolt that drives the thread. At this time, the driven member can be a nut structure. The active member can also be a gear, and the driven member is a rack.

[0079] In the present application, the second adjustment component 30 is designed to include a second linear reciprocating motion mechanism 31 , and the cover plate 11 can be adjusted left and right in two opposite sub-directions of the second direction Y by utilizing the action of the second linear reciprocating motion mechanism 31 .

[0080] In some examples, optionally, the second linear reciprocating motion mechanism 31 of the present embodiment includes a second connecting member 311, a third connecting member 312 and a second adjusting screw 313, the second connecting member 311 is used to connect the welding frame 200, the second adjusting screw 313 can be installed on the second connecting member 311 axially rotatable around its own axis, the third connecting member 312 is installed on the end plate 12 and is threadedly connected to the second adjusting screw 313, and the rotation of the second adjusting screw 313 drives the third connecting member 312, the end plate 12 and the cover plate 11 to move along the second direction Y.

[0081] The second connecting member 311 of the present embodiment is used to connect the welding frame 200, and can serve as a mounting structure for one end of the second adjusting screw 313. The second adjusting screw 313 and the third connecting member 312 of the present embodiment form a screw nut structure. The third connecting member 312 can be understood as a nut that can only move linearly along the second direction Y. The linear reciprocating motion of the third connecting member 312 is achieved by rotating the second adjusting screw 313, thereby driving the end plate 12 and the cover plate 11 to move in the first direction X. The structure is simple and easy to operate.

[0082] Combined with Figure 3 , Attachment Figure 4 and attached Figure 5 As shown in , in some examples, optionally, the second connecting member 311 of this embodiment is provided with a second locking structure 3111, and the second locking structure 3111 is used to connect the welding frame 200 and to limit the movement of the end plate 12 along the second direction Y.

[0083] After adjusting the position of the positioning assembly 10 along the second direction Y, the adjusted end plate 12 and cover plate 11 can be locked by the second locking structure 3111 of this embodiment, thereby reducing the possibility of unnecessary displacement of the end plate 12 and cover plate 11 after position adjustment, and further improving the stability of the positioning welding part 13 on the cover plate 11 and the battery after positioning.

[0084] In some examples, optionally, the second locking structure 3111 of the present embodiment includes a second sliding hole 31111 and a second locking member 31112 , and the second locking member 31112 is slidably connected to the second sliding hole 31111 and is used for detachable connection with the welding frame 200 .

[0085] Similar to the aforementioned first locking structure 122, the second locking member 31112 of the present embodiment may be a screw or a bolt. Accordingly, the welding frame 200 is provided with a second connecting hole (not shown in the figure) which is detachably connected to the screw or the bolt. The second connecting hole may be a screw hole or a socket. When the position of the end plate 12 and the cover plate 11 along the second direction Y is adjusted, the second locking member 31112 of the present embodiment is not connected to the second connecting hole. After adjusting the position of the cover plate 11, the second locking member 31112 in the second sliding hole 31111 can be slid so that the second locking member 31112 is aligned with the second connecting hole, thereby completing the locking between the end plate 12 and the welding frame 200 in the second direction Y.

[0086] Combined with Figure 1 and attached Figure 3 and attached Figure 5 As shown in FIG. 1 , the end plate 12 of the present embodiment is provided with at least one first receiving hole 123 , and at least one second linear reciprocating motion mechanism 31 is provided in the first receiving hole 123 .

[0087] The first receiving hole 123 of this embodiment receives the second linear reciprocating motion mechanism 31, which can reduce the space occupied by the second adjustment assembly 30. The number of the first receiving holes 123 can be multiple, for example, each end plate 12 has two first receiving holes 123 in the figure, and each first receiving hole 123 can have multiple second linear reciprocating motion mechanisms 31, such as two in the figure, which can improve the stability of the rear end plate 12 after adjustment.

[0088] The two second linear reciprocating motion mechanisms 31 located in the same accommodating hole can be symmetrically arranged in the first accommodating hole 123, so that when the two second adjusting screws 313 of the two second linear reciprocating motion mechanisms 31 rotate, the two third connecting members 312 have the same movement tendency (not shown in the figure), or the two third connecting members 312 have opposite movement tendencies as shown in the figure. This structure in which the two third connecting members 312 have opposite movement tendencies can adjust the rotation direction of the two second adjusting screws 313 to the opposite direction when adjusting the position of the end plate 12 in the second direction Y, or only adjust one of them during adjustment, and release the connection with the second connecting member 311 when the second adjusting bolt of the other one needs to be adjusted again, and then connect again after adjustment to play a locking role.

[0091] Therefore, this embodiment can adjust the distance between the multiple positioning welding parts 13 on the first plate body 111 and the multiple positioning welding parts 13 on the second plate body 112 by configuring the third adjustment component 40, so that the multiple positioning welding parts 13 on the cover plate 11 can adapt to batteries of different specifications, which can improve the applicability of the battery positioning welding tooling.

[0092] The third adjustment assembly 40 of this embodiment may have the same or different operating principles as the first adjustment assembly 20 and the second adjustment assembly 30. For example, the third adjustment assembly 40 may include a sliding member 41, and the sliding member 41 may move on the first plate body 111 along the first direction X, thereby driving the second plate body 112 to move. The movement of the sliding member 41 may be realized manually or by installing a gas rod, a hydraulic rod, an electric rod, or the like.

[0093] In some examples, optionally, the first plate body 111 and the second plate body 112 of the present embodiment may be designed as a multi-layer structure, for example, the first plate body 111 includes a plurality of sub-plate bodies connected in a stacked manner along a third direction Z. Similarly, the second plate body 112 includes a plurality of sub-plate bodies connected in a stacked manner along a third direction Z. By designing the first plate body 111 and the second plate body 112 as a multi-layer structure, the structural strength of the first plate body 111 and the second plate body 112 may be improved.
