[0045] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0046] As the demand for power batteries continues to increase, the requirements for battery production efficiency are also becoming increasingly higher. During the battery production process, battery assembly and assembly are largely dependent on assembly tools, and the structure of assembly tools directly affects the battery assembly efficiency.

[0047] Batteries typically consist of multiple battery modules. Each battery module includes a housing and multiple battery cells. The housing consists of a box body and a cover. The box body is a box-shaped structure with a top opening. The cover fits over the top opening, forming a closed space with the box body. Multiple battery cells are placed within this closed space. Furthermore, this closed space is typically filled with electrolyte.

[0048] The box body generally includes a bottom plate, two opposite side plates and two opposite end plates arranged on the bottom plate. In the related art, the side plates and the end plates are connected by welding. When welding the side plates and the end plates, a manipulator and a clamp are generally required. The manipulator and the clamp are used to move the battery module, the end plate, the side plates, etc. from the initial position to the workstation where the welding system is located. The battery cells are then shaped by the centering mechanism and the pole pressing mechanism in the welding clamping mechanism of the welding system. After that, the side plates and the end plates are welded by the welding equipment in the welding system.

[0049] The centering mechanism is independent of the fixture. After the battery cell is positioned, a gantry is used to transport the centering mechanism to the appropriate location for centering and shaping the battery cell. After shaping, the centering mechanism needs to be transported away by the gantry to avoid interference with subsequent welding tooling and affecting the welding process.

[0050] Using a gantry to transport the striking mechanism will make the striking process more complicated; moreover, the gantry is large in size and occupies a large space, which is not conducive to structural layout.

[0051] To alleviate the above-mentioned problems, an embodiment of the present application provides a centering mechanism, which includes a first driving device. The first driving device can drive the centering component to move relative to the support frame, so that the centering component moves in a direction perpendicular to the support surface of the support frame for supporting the battery module, thereby realizing position movement before centering. The first driving device replaces the gantry, and the first driving device and the centering component are integrated together, which can not only simplify the structure of the centering mechanism, but also simplify the operating procedures, which is conducive to improving the production efficiency of the battery.

[0052] The following is a description of an embodiment of the hitting mechanism provided in this application.

[0053] refer to Figure 1 and Figure 2 As shown, in some embodiments of the centering mechanism provided in the present application, the centering mechanism includes a support frame 1, a centering component 2 and a first driving device 3, the support frame 1 is configured to support the battery module 10, the centering component 2 includes two clamping members 21, the two clamping members 21 are respectively arranged on both sides of the battery module 10 along the first direction x, the two clamping members 21 are configured to clamp the battery module 10 to adjust the relative position of each battery cell 101 in the battery module 10 in the first direction x, the first driving device 3 is arranged on the support frame 1, the first driving device 3 is driven and connected to the centering component 2, the first driving device 3 is configured to drive the centering component 2 to move relative to the support frame 1 along the second direction y, and the second direction y is perpendicular to the support surface of the support frame 1 for supporting the battery module 10.

[0054] Among them, the centering operation of the centering component 2 includes clamping the battery module 10 through two clamping parts 21, adjusting the relative position of each battery cell 101 in the battery module 10 in the first direction x, so that each battery cell 101 remains flush in the first direction x, thereby ensuring that the subsequent welding process of the end plate and side plate can proceed smoothly.

[0055] In the above embodiment, the first drive device 3 can drive the centering component 2 to move relative to the support frame 1 in a direction perpendicular to the support surface of the support frame 1, so as to realize the position movement of the centering component 2 before clamping and centering. The first drive device 3 replaces the gantry to drive the centering component 2 to move relative to the battery module 10, and the centering component 2 and the first drive device 3 are integrated into the centering mechanism, which can effectively simplify the overall structure of the centering mechanism. By driving the centering component 2 to move with the first drive device 3 integrated with the centering component 2, there is no need to wait for the gantry to move into place, thereby effectively simplifying the centering process and improving the centering efficiency.

[0056] In some embodiments, the first driving device 3 includes an oil cylinder, a pneumatic cylinder, or a motor.

[0057] In some embodiments, the centering mechanism further includes a locking mechanism 4, which is configured to keep the centering component 2 and the support frame 1 relatively fixed in the second direction after the first driving device 3 drives the centering component 2 to move to a preset position.

[0058] By setting up a locking mechanism 4, after the first driving device 3 drives the hitting component 2 to move to a preset position, the hitting component 2 and the support frame 1 can be kept relatively fixed in the second direction, preventing the hitting component 2 from making accidental movements relative to the support frame 1 during the hitting process, thereby improving the stability and safety of the hitting process.

[0059] There are many options for the specific structure of the locking mechanism 4.

[0060] like Figures 2 to 4 As shown, in some embodiments, the locking mechanism 4 includes a pin 41, the hitting component 2 includes a positioning plate 22 connected to the first driving device 3, the positioning plate 22 is provided with a first hole, and the support frame 1 is provided with a second hole. The pin 41 is inserted into the first hole and the second hole to achieve relative fixation between the hitting component 2 and the support frame 1 in the second direction.

[0061] By setting the pin 41, the support frame 1 and the positioning plate 22 can be connected, thereby maintaining the relative fixation between the hitting component 2 and the support frame 1 in the second direction, preventing the hitting component 2 and the support frame 1 from relative movement during the hitting process, affecting the hitting operation.

[0062] The locking mechanism 4 uses the latch 41 to pass through the first hole and the second hole to achieve locking, which can effectively simplify the structure of the locking mechanism 4, and is also relatively simple to operate, easy to implement, and has relatively high reliability and stability.

[0063] The latch 41 may be cylindrical or square-shaped.

[0064] In some embodiments, the locking mechanism 4 includes a second driving device 42 mounted on the support frame 1 , the second driving device 42 is drivingly connected to the latch 41 , and the second driving device 42 is configured to drive the latch 41 to move relative to the support frame 1 .

[0065] By providing the second drive device 42, the latch 41 can be driven by the second drive device 42 to move relative to the support frame 1, eliminating the need for manual operation, reducing labor intensity, and also helping to save labor costs. Using the second drive device 42 to drive the latch 41 relative to the support frame 1 also helps to improve the timeliness, accuracy, and efficiency of the locking of the latch 41.

[0066] In some embodiments, the second driving device 42 includes an oil cylinder, a pneumatic cylinder, or a motor.

[0067] In some embodiments, the centering assembly 2 includes a support 23 and a third driving device 24 mounted on the support 23 , and the third driving device 24 is configured to drive the clamping member 21 to move along a first direction relative to the battery module 10 .

[0068] By providing the third driving device 24 , the clamping member 21 can be driven to move along the first direction relative to the battery module 10 , thereby achieving automatic movement of the clamping member 21 and automatic clamping of the battery module 10 .

[0069] The number of third drive devices 24 can be flexibly set as needed. For example, there can be one third drive device 24, which drives the two clamping members 21 to move synchronously via the connecting assembly; or there can be two third drive devices 24, which each drive a corresponding clamping member 21 to move.

[0070] In some embodiments, the third driving device 24 includes an oil cylinder, a pneumatic cylinder, or a motor.

[0071] In some embodiments, the shooting component 2 includes a first support plate 25, a second support plate 26 and multiple third support plates 27, the first support plate 25 is driven and connected to the third driving device 24, the clamping member 21 is installed on the second support plate 26, and the multiple third support plates 27 are connected between the first support plate 25 and the second support plate 26 at intervals.

[0072] By providing the first support plate 25, the second support plate 26 and the third support plate 27, the power transmission of the third driving device 24 can be realized, so that the third driving device 24 drives the first support plate 25, the second support plate 26 and the third support plate 27 to drive the clamping member 21 to move, thereby realizing the clamping action.

[0073] The plurality of third support plates 27 are connected between the first support plate 25 and the second support plate 26 at intervals, which can improve the connection strength between the first support plate 25 and the second support plate 26 .

[0074] In some embodiments, the third support plate 27 includes a first support portion 271 connected to the second support plate 26, a second support portion 272 connected to the first support plate 25, and a third support portion 273 connected between the first support portion 271 and the second support portion 272, the first support portion 271 is arranged on the clamped side of the battery module 10, and the second support portion 272 is arranged on the supported side of the battery module 10.

[0075] By setting the third support plate 27 to include a first support part 271, a second support part 272 and a third support part 273, and the first support part 271 is set on the clamped side of the battery module 10, and the second support part 272 is set on the side of the battery module 10 close to the support frame 1, the third driving device 24 connected to the first support plate 25 can be set on the supported side of the battery module 10.

[0076] Compared with the solution of setting the third driving device 24 on the clamped side of the battery module 10, the embodiment of the present application adopts the solution of setting the third driving device 24 on the supported side of the battery module 10, which can effectively reduce the overall size of the hitting mechanism in the first direction x, thereby reducing the size of the space occupied by the hitting mechanism.

[0077] In some embodiments, the supporting surface includes a first supporting surface 11 and a second supporting surface 12 in contact with the first surface of the battery module 10 , with a gap 13 between the first supporting surface 11 and the second supporting surface 12 .

[0078] By setting the supporting surface to include a first supporting surface 11 and a second supporting surface 12, and a gap 13 between the first supporting surface 11 and the second supporting surface 12, the area of ​​the supporting surface can be reduced, thereby preventing the first supporting surface 11 and the second supporting surface 12 from interfering with the structure on the supported surface of the battery module 10 or crushing the components arranged on the supported surface of the battery module 10, thereby effectively protecting the battery module 10.

[0079] The following is combined with Figures 1 to 4 , the structure and working process of an embodiment of the hitting mechanism provided in this application are described.

[0080] like Figure 1 and Figure 2 As shown, the hitting mechanism includes a support frame 1, a hitting component 2, a first driving device 3 and a locking mechanism 4.

[0081] The main body of the support frame 1 is a trough-shaped structure with an opening facing downwards. The bottom of the support frame 1 includes two connecting rods, and the support frame 1 is installed on the base plate of the fixture through the two connecting rods.

[0082] The centering assembly 2 includes a clamping member 21 , a positioning plate 22 , a support 23 , a third driving device 24 , a first support plate 25 , a second support plate 26 , a third support plate 27 and a connecting plate 28 .

[0083] There are two clamping members 21 , and the clamping members 21 are in the form of an elongated plate.

[0084] The positioning plate 22 is an elongated plate-like structure. The number of supports 23 is the same as the number of third drive devices 24. The first support plate 25 and the second support plate 26 are both elongated plate-like structures. The third support plate 27 is bent. The connecting plate 28 is a block-like structure.

[0085] The positioning plate 22 is drivably connected to the first drive device 3. The first drive device 3 moves up and down along the y-direction. The support 23 is mounted on the positioning plate 22, and the third drive device 24 is mounted on the support 23. The driving end of the third drive device 24 is connected to the connecting plate 28, which is connected to the first support plate 25. The third support plate 27 is connected between the first support plate 25 and the second support plate 26. The second support plate 26 is connected to the clamping member 21. The third drive device 24 moves left and right along the x-direction, driving the clamping member 21 to move left and right along the x-direction, thereby clamping the left and right sides of the battery module 10.

[0086] like Figure 3 As shown, the clamping member 21 is in contact with and clamped to the battery module 10 .

[0087] like Figure 4 As shown, the locking mechanism 4 includes a latch 41 and a second driving device 42 , and the second driving device 42 drives the latch 41 to be inserted into the first hole and the second hole, or to be pulled out from the first hole and the second hole.

[0088] The working process of the auction agency is as follows:

[0089] After the battery module 10 is placed on the support surface of the support frame 1, the third driving device 24 starts to operate, opening the two clamping members 21 and increasing the distance between the two clamping members 21;

[0090] Then, the first driving device 3 starts to move, driving the positioning plate 22 to drive the clamping member 21, the support 23, the third driving device 24, the first supporting plate 25, the second supporting plate 26, the third supporting plate 27 and the connecting plate 28 to move upward together;

[0091] After the clamping member 21 reaches both sides of the battery module 10, the second driving device 42 starts to operate, inserting the pin 41 into the first hole and the second hole to maintain the relative fixation between the positioning plate 22 and the support frame 1 in the y direction;

[0092] Then, the third driving device 24 starts to operate, driving the connecting plate 28 to move the clamping member 21, the first support plate 25, the second support plate 26, and the third support plate 27 together toward the battery module 10 until the two clamping members 21 respectively contact the two sides of the battery module 10, flattening the multiple battery cells 101 in the battery module 10, and completing the catching operation;

[0093] Then, the third driving device 24 continues to operate, and the two clamping members 21 move away from the battery module 10;

[0094] After the clamping member 21 leaves the preset distance, the second driving device 42 moves in the reverse direction to pull the latch 41 out of the first hole and the second hole, thereby releasing the relative fixation between the positioning plate 22 and the support frame 1 in the y direction;

[0095] Next, the first driving device 3 moves in the reverse direction, driving the positioning plate 22, the clamping member 21, the support 23, the third driving device 24, the first supporting plate 25, the second supporting plate 26, the third supporting plate 27 and the connecting plate 28 to move downward together, so as to prevent these components from interfering with the subsequent welding operation;

[0096] Finally, the third driving device 24 is activated again to retract the two clamping members 21 to reduce the width of the centering mechanism in the x direction during the waiting period.

[0097] The embodiment of the present application replaces the gantry with a first drive device integrated in the striking mechanism, which can effectively simplify the structure of the striking mechanism and the fixture, simplify the striking operation, reduce the beat of the welding room fixture, and improve the striking efficiency; it can also facilitate changeover and replacement, and facilitate maintenance.

[0098] Based on the hitting mechanism in each of the above embodiments, the present application also provides a clamp, which includes a substrate and a hitting mechanism installed on the substrate.

[0099] By installing the centering mechanism on the substrate, the centering mechanism can be integrated into the fixture, so that the fixture has its own centering mechanism, which is beneficial to reducing the time waiting for the centering mechanism to be in place during the welding process, reducing the cycle of the welding room fixture, thereby improving welding efficiency and improving battery production efficiency.

[0100] Based on the hitting mechanism or clamp in each of the above embodiments, the present application also provides a welding system, which includes the hitting mechanism or clamp.

[0101] The positive effects of the hitting mechanism in each of the above embodiments are also applicable to the clamp and welding system and will not be described in detail here.

[0102] The above description of the various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced with each other and will not be repeated herein for the sake of brevity.

[0103] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and components may be substituted with equivalents without departing from the scope of the present application. In particular, the various technical features described in the various embodiments may be combined in any manner as long as there are no structural conflicts.
