[0030] The embodiments of this application are described below with reference to the accompanying drawings. It can be understood that the technical features involved in the different embodiments described below can be combined with each other as long as they do not conflict with each other.

[0031] Reference Figure 1 and Figure 2 This application provides a battery module production apparatus comprising a first component 10, a second component 20, and a drive mechanism 30. The first component 10 includes a first support member 110 and a first clamping member 120 disposed on the first support member 110. The second component 20 includes a second support member 210 and a second clamping member 220 disposed on the second support member 210. The drive mechanism 30 can drive the first support member 110 and the second support member 210 to move closer together and also drive the first clamping member 120 and the second clamping member 220 to move closer together. When the first support member 110 and the second support member 210 move closer together and contact each other, at least a portion of the structure on the first support member 110 and the second support member 210 can jointly support the battery module. A clamping space 125 is formed between the first clamping member 120 and the second clamping member 220, and both provide positioning and clamping forces to the battery module 80.

[0032] In some embodiments, the drive mechanism 30 can drive the first support member 110 and the second support member 210 to move closer together and cause the first clamping member 120 and the second clamping member 220 to move closer together. At least a portion of the structures on the first support member 110 and the second support member 210 together form a support portion. A clamping space 125 is formed between the first clamping member 120 and the second clamping member 220, and both are used to position and provide clamping force for the assembled battery module 80. The support portion is used to support the battery module 80. The structural design in this application is reasonable, and the assembly positioning of the battery module 80 is accurate, which is beneficial to improving product consistency. Moreover, the battery module production device proposed in this application is easy to operate, highly practical, and beneficial to improving production efficiency.

[0033] Specifically, when the first support member 110 and the second support member 210 approach and contact each other, the first clamping member 120 and the second clamping member 220 are closest to each other. The heat exchange plate 810 and multiple individual batteries 820 can then be sequentially placed between the first clamping member 120 and the second clamping member 220, with the first support member 110 and the second support member 210 providing support, thus facilitating the assembly of the battery module 80. More specifically, the first clamping member 120, the second clamping member 220, the first support plate, and the second support plate form an assembly frame for the battery module 80. Using this frame as a positioning reference, the heat exchange plate 810 and multiple individual batteries 820 are stacked, enabling precise assembly of each part. The drive mechanism 30 provides a locking force to counteract the outward expansion of the battery module 80.

[0034] For example, refer to Figure 1 and Figure 2 The battery module production apparatus also includes a frame 40, on which a first slide rail 410 is provided along a first direction X. A first support member 110 and a second support member 210 are slidably connected to the first slide rail 410. A drive mechanism 30 is disposed on the frame 40 and can drive the first support member 110 and the second support member 210 to move closer or further apart along the first slide rail 410. Further, referring to… Figure 1 and Figure 2 Multiple first slide rails 410 can be provided, and multiple first slide rails 410 are spaced apart along the second direction Y. Multiple first slide rails 410 together support the first support member 110 and the second support member 210, making the movement of the first support member 110 and the second support member 210 more stable.

[0035] For example, refer to Figure 1 and Figure 2The drive mechanism 30 includes a lead screw 310, a lead screw nut 320, a bearing housing 330, and a drive wheel 340. The bearing housing 330 is mounted on the frame 40 and supports the lead screw 310. There are two lead screw nuts 320, which are respectively connected to the first support member 110 and the second support member 210. The lead screw 310 may have two threaded areas with opposite helical directions. The two lead screw nuts 320 are fitted onto the lead screw 310 and respectively connected to the two threaded areas on the lead screw 310, so that when the lead screw 310 rotates, the two lead screw nuts 320 move closer or further apart, thereby causing the first support member 110 and the second support member 210 to move closer or further apart. The drive wheel 340 is connected to the lead screw 310. Electric or manual forward or reverse rotation of the drive wheel 340 can achieve the corresponding rotation of the lead screw 310, and achieve the purpose of moving the first support member 110 and the second support member 210 closer or further apart.

[0036] Understandably, the drive mechanism 30 can also be implemented in other ways. For example, it is also advisable to set up two sets of linear motors, hydraulic cylinders, pneumatic cylinders and other mechanisms to drive the first support member 110 and the second support member 210 respectively. Other implementation methods will not be described in detail here.

[0037] In some embodiments, the relative position between the first clamping member 120 and the first support member 110 is adjustable, and / or the relative position between the second clamping member 220 and the second support member 210 is adjustable; after the battery module 80 is assembled, the first support member 110 and the second support member 210 remain stationary, and the first clamping member 120 and the second clamping member 220 are adjusted to move away from each other so that the battery module 80 can be removed from the clamping space 125.

[0038] It should be noted that the heat exchange plate 810 and the multiple individual cells 820 are bonded together with an adhesive. The first clamping member 120 and the second clamping member 220 provide clamping force to the battery module 80 and maintain the clamping force for a period of time, which is the assembly and pressure holding process of the battery module, so as to wait for the adhesive to solidify and make the connection between the heat exchange plate 810 and the multiple individual cells 820 tighter.

[0039] In this embodiment, after the battery module 80 has completed the pressure holding process, the first support member 110 and the second support member 210 remain stationary, continuing to support the battery module 80. The battery module 80 can be detached simply by adjusting the first clamping member 120 and the second clamping member 220 to move further apart. This embodiment is convenient to operate, highly practical, and ensures the smooth detachment of the battery module 80, while also preventing the battery module 80 from falling and affecting its assembly effect.

[0040] Understandably, the first support member 110 and the second support member 210 can remain stationary by the locking force provided by the drive mechanism 30. Alternatively, the battery module 80 can be detached by the drive mechanism 30 driving the first support member 110 and the second support member 210 away from each other and causing the first clamping member 120 and the second clamping member 220 to move away from each other. However, this method would cause the battery module 80 to lose support and be prone to falling.

[0041] Furthermore, in this embodiment, the relative positions between the first clamping member 120 and the first support member 110 can be pre-adjusted, and / or the relative positions between the second clamping member 220 and the second support member 210 can be pre-adjusted to achieve assembly and positioning of battery modules 80 of different specifications and sizes, which has strong versatility.

[0042] In some embodiments, refer to Figure 1 The first clamping member 120 includes a first plate 121 and a second plate 122. The first component 10 also includes a first locking member 130. The first plate 121 is slidably connected to the first support member 110, and the two are fixed in relative position by the first locking member 130. The second plate 122 is set at an angle to the first plate 121 and is used to press against the battery module 80. And / or, the second clamping member 220 includes a third plate 221 and a fourth plate 222. The second component 20 also includes a second locking member 230. The third plate 221 is slidably connected to the second support member 210, and the two are fixed in relative position by the second locking member 230. The fourth plate 222 is set at an angle to the third plate 221 and is used to press against the battery module 80.

[0043] In this embodiment, a specific implementation method is proposed that allows for movable adjustment between the first clamping member 120 and the first support member 110, and between the second clamping member 220 and the second support member 210.

[0044] Optionally, both the first support member 110 and the second support member 210 are plate structures, wherein the first plate 121 is parallel to the first support member 110, the second plate 122 is perpendicular to the first plate 121; the third plate 221 is parallel to the second support member 210, and the fourth plate 222 is perpendicular to the third plate 221.

[0045] Specifically, in combination Figure 1 and Figure 2 The first support member 110 is provided with a second slide rail 140 distributed along the first direction X, and the first plate 121 is slidably connected to the second slide rail 140; the second support member 210 is provided with a third slide rail 240 along the first direction X, and the third plate 221 is slidably connected to the third slide rail 240.

[0046] It should be noted that before assembling and positioning the battery module 80, the first locking member 130 locks the relative position of the first support member 110 and the first plate 121, and the second locking member 230 locks the relative position of the second support member 210 and the third plate 221. The driving mechanism 30 drives the first support member 110 and the second support member 210 to move closer to each other, thereby driving the first plate 121 and the third plate 221 to move closer to each other, that is, driving the second plate 122 and the fourth plate 222 to move closer to each other, forming a clamping space 125 between the second plate 122 and the fourth plate 222. After the battery module 80 has been pressurized, the first support member 110 and the first plate 121 are unlocked, and the second support member 210 and the third plate 221 are unlocked, so that the positions of the first support member 110 and the second support member 210 remain unchanged. The first clamping member 120 and the second clamping member 220 are adjusted to move away from each other along the second slide rail 140 and the third slide rail 240, respectively, so that the battery module 80 can be easily removed.

[0047] Optionally, both the first locking member 130 and the second locking member 230 are locking pins. The first plate 121 and the first support member 110 are provided with pin holes 111 at the corresponding positions. The locking pin passes through the pin holes 111 of the first plate 121 and the first support member 110 to lock the first plate 121 and the first support member 110, so that their relative positions are fixed. The third plate 221 and the second support member 210 can be set in the same way.

[0048] In some embodiments, refer to Figure 1 The first clamping member 120 further includes a first insulating member 123, which is disposed on the second plate 122, and the second plate 122 contacts the battery module 80 through the first insulating member 123; and / or, the second clamping member 220 further includes a second insulating member 223, which is disposed on the fourth plate 222, and the fourth plate 222 contacts the battery module 80 through the second insulating member 223.

[0049] In this embodiment, the first insulating member 123 and the second insulating member 223 are in direct contact with the battery module 80 to avoid external short circuits in the battery module 80 or a single battery 820 during assembly, which could cause safety issues.

[0050] Optionally, the first insulating element 123 and the second insulating element 223 can be gaskets or plate structures, which can be respectively attached to the inner surfaces of the second plate 122 and the fourth plate 222.

[0051] Optionally, the first insulating member 123 and the second insulating member 223 may be made of flexible materials, thereby achieving flexible contact with the battery module 80 and avoiding damage to the battery module 80.

[0052] In some embodiments, refer to Figure 1The first clamping member 120 further includes a first reinforcing plate 124, which is connected between the first plate body 121 and the second plate body 122; and / or, the second clamping member 220 further includes a second reinforcing plate 224, which is connected between the third plate body 221 and the fourth plate body 222.

[0053] In this embodiment, the first reinforcing plate 124 can support the second plate 122, and the second reinforcing plate 224 can support the fourth plate 222, so as to avoid excessive outward pressure on the battery module 80, which would cause the first plate 121 and the fourth plate 222 to tilt outward, affecting the positioning and pressure holding effect of the battery module 80.

[0054] In some embodiments not shown in the figures, the battery module production apparatus further includes a pressure detection device for detecting the clamping force of the first clamping member 120 and the second clamping member 220 on the battery module.

[0055] In this embodiment, the holding pressure is monitored in real time, which facilitates the adjustment of the holding pressure using the drive mechanism 30, avoiding excessive pressure that could damage the battery module 80, or insufficient pressure that could affect the holding effect. Specifically, the pressure detection device can be a force sensor, which is coupled to the first clamping member 120 and the second clamping member 220 to detect the clamping force between the first clamping member 120 and the second clamping member 220. The force sensor can be in contact with or not in contact with the first clamping member 120 and the second clamping member 220. In this embodiment, the orientation of the pressure detection device is not limited.

[0056] In some embodiments, refer to Figures 1 to 4 The first clamping member 120 and the second clamping member 220 can press against the battery module 80 along the first direction X; the battery module production device also includes a first positioning mechanism 50 and a second positioning mechanism 60, which can press against the two ends of the battery module 80 along the second direction Y respectively; wherein, the first direction X and the second direction Y are perpendicular to each other.

[0057] In this embodiment, the first positioning mechanism 50 and the second positioning mechanism 60 can respectively position and press the two ends of the battery module 80 along the second direction Y, and cooperate with the first component 10 and the second component 20 to complete the positioning and pressure holding function of the battery module 80 during the assembly process, so that the positioning is more accurate, the pressure holding effect is better, and the consistency of the product is further improved.

[0058] Optionally, refer to Figure 1 and Figure 2 The first positioning mechanism 50 and the second positioning mechanism 60 may both be located on the frame 40 and respectively at both ends of the first component 10 and / or the second component 20 along the second direction Y.

[0059] In some embodiments, refer to Figure 3 and Figure 4 The first positioning mechanism 50 can elastically abut against the first end of the battery module 80 along the second direction Y, and / or the second positioning mechanism 60 can elastically abut against the second end of the battery module 80 along the second direction Y.

[0060] In this embodiment, the first positioning mechanism 50 and the second positioning mechanism 60 elastically abut against the end of the battery module 80, which facilitates the assembly operation of placing the battery module 80 into the clamping space 125. They also provide clamping force to ensure pressure retention and act as a buffer to prevent damage to the battery module 80.

[0061] Understandably, combined Figure 3 and Figure 4 It is also a desirable implementation method that the first positioning mechanism 50 rigidly abuts against the first end of the battery module 80 along the second direction Y, and the second positioning mechanism 60 elastically abuts against the second end of the battery module 80 along the second direction Y through an elastic member 621 (e.g., a spring).

[0062] In some embodiments, combined with Figure 3 and Figure 4 The battery module 80 includes a heat exchange plate 810 and a plurality of batteries 820 that are attached to each other. The first positioning mechanism 50 includes a first positioning structure 510 and a second positioning structure 520. The first positioning structure 510 is used to press against the first end of the heat exchange plate 810 along the second direction Y, and the second positioning structure 520 is used to press against the battery 820 located at the outermost end of the first end of the second direction Y. And / or, the second positioning mechanism 60 includes a third positioning structure 610 and a fourth positioning structure 620. The third positioning structure 610 is used to press against the second end of the heat exchange plate 810 along the second direction Y, and the fourth positioning structure 620 is used to press against the battery 820 located at the outermost end of the second end of the second direction Y.

[0063] In this embodiment, the first positioning structure 510 and the third positioning structure 610 press against the two ends of the heat exchange plate 810 along the second direction Y, and the second positioning structure 520 and the fourth positioning structure 620 press against the two ends of the battery assembly formed by multiple batteries 820 along the second direction Y. The positioning method is reasonably designed and has better adaptability to the battery module 80.

[0064] Optionally, refer to Figure 3 and Figure 4The heat exchange plate 810 is provided with multiple batteries 820 on both sides along the first direction X, that is, the heat exchange plate 810 is located in the middle of the two battery layers. The second positioning structure 520 includes two positioning parts arranged at intervals along the first direction X. The two positioning parts are respectively connected to the first component 10 and the second component 20, and the two positioning parts are respectively used to press against the two battery layers. The fourth positioning structure 620 can also be arranged in the same way.

[0065] In some embodiments, combined with Figure 3 and Figure 4 The heat exchange plate 810 extends from at least one end of the clamping space 125 along the second direction Y and is provided with a liquid line connector 811; the battery module production device also includes a docking mechanism 70, which is used to clamp the tube body 90 and move it towards the liquid line connector 811 to realize the docking of the tube body 90 and the liquid line connector 811; wherein, the docking path of the docking mechanism 70 is staggered with the first positioning mechanism 50 and / or the second positioning mechanism 60 in the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0066] In this embodiment, the docking mechanism 70 can clamp the tube body 90 and bring it close to the liquid line connector 811 at the end of the heat exchange plate 810 to achieve docking between the tube body 90 and the liquid line connector 811. The docking path is preset, and the docking process is precise and stable. Moreover, the docking mechanism 70 and the first positioning mechanism 50 and / or the second positioning mechanism 60 are staggered in the third direction Z, so that the docking mechanism can clamp the tube body 90 and move it along the first direction X to achieve docking between the tube body 90 and the liquid line connector 811, avoiding interference between the docking mechanism 70 and the first positioning mechanism 50 and / or the second positioning mechanism 60.

[0067] It should be noted that, referring to Figure 1 Liquid line connectors 811 can be respectively provided at both ends of the heat exchange plate 810 along the second direction Y, and two sets of docking mechanisms 70 are correspondingly provided on the frame 40 to connect the tube body 90 with the liquid line connectors 811, thus forming an inlet liquid line and an outlet liquid line. In some embodiments not shown in the figure, the two liquid line connectors 811 on the heat exchange plate 810 can also be provided at the same end of the second direction Y, and two sets of docking mechanisms 70 are provided on the same side to connect the tube body 90 with the liquid line connectors 811, which is also a preferred implementation.

[0068] Optionally, the docking mechanism 70 includes a clamping part 710 and a fourth slide rail 720. The fourth slide rail 720 is disposed on the frame 40 and distributed along the first direction X. The clamping part 710 is used to clamp the tube body 90 and slides in connection with the fourth slide rail 720, thereby planning the docking path and ensuring the accuracy and stability of the docking movement process.

[0069] In addition, the battery module production device also includes a support mechanism 100. The support mechanism 100 is located on the frame 40 and can support the end of the liquid line connector 811 facing away from the docking mechanism 70. When the docking mechanism 70 docks the tube 90 with the liquid line connector 811, the support mechanism 100 provides support force to the liquid line connector 811 to prevent the docking mechanism 70 from applying too much pressure to the liquid line connector 811, causing the liquid line connector 811 to fall off and resulting in docking failure.

[0070] It should be noted that the battery module production apparatus in this embodiment may also include other components, such as a display device 420 for displaying the pressure measured by the pressure detection device, a walking wheel 430 located at the bottom of the frame 40, etc. Other components will not be described here.

[0071] In particular, the term "and / or" in this application should be understood as follows:

[0072] In the first case, the term “and / or” between the first subject and the second subject includes any of the following meanings: (1) only the first subject; (2) only the second subject; and (3) both the first subject and the second subject.

[0073] In the second case, the term "and / or" between the last two of three or more subjects means including at least any one of the subjects. For example, "first subject, second subject and / or third subject" has the same meaning as "first subject and / or second subject and / or third subject", specifically including the following combinations: (1) only the first subject; (2) only the second subject; (3) only the third subject; (4) first subject and second subject and no third subject; (5) first subject and third subject and no second subject; (6) second subject and third subject and no first subject; and (7) first subject, second subject and third subject;

[0074] Furthermore, the character " / " in this application indicates that the objects before and after it are in an "or" relationship.

[0075] Finally, although the embodiments of this application have been described above in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the concept of this application, and such modifications and variations all fall within the scope of protection of this application.
