Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a processing device. Background Art

[0002] The Cell Contact System (CCS) integrated busbar system consists of structural components such as brackets (injection molding, blister packaging, or PET hot-pressed film), aluminum bars, and wiring harnesses (PCBs and FPCs). The aluminum bars on the CCS connect multiple cells in series and parallel to form battery modules. The wiring harnesses (PCBs and FPCs) detect and monitor the cell voltage and temperature in real time, transmitting these signals to the BMS (Battery Management System) for overcurrent protection and thermal runaway management. The battery module data collection system (CCS), as the core component of the safety monitoring center for new energy vehicle power batteries and energy storage batteries, plays a key role in the safety performance of battery packs.

[0003] Currently, ensuring accurate spacing between the poles of adjacent cells in a battery module is crucial in the processing of CCS integrated busbars, as it directly impacts the module's electrical performance and mechanical stability. Existing technology typically relies on precise mold design and manual measurement to determine pole spacing. This necessitates the design of molds of varying sizes for each cell size, leading to high processing costs and long production cycles for CCS integrated busbars. Manual measurement, on the other hand, is less accurate. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1 、 Figure 2 and Figure 3 As shown, Figure 1 This is a schematic diagram of the overall structure of the processing device provided by the embodiment of the utility model. Figure 2 This is a schematic diagram of the exploded structure of the base assembly 20 provided in an embodiment of the present invention. Figure 3 It is a schematic diagram of the overall structure provided by an embodiment of the utility model.

[0035] The embodiment of the present utility model provides a processing device, including: a base assembly 20, a plurality of positioning assemblies 30 and a plurality of identification assemblies 40, the base assembly 20 includes a first base 21 and a plurality of second bases 22, the second base 22 is slidably arranged on the first base 21 along a first direction, the positioning assembly 30 is slidably connected to the second base 22 along a second direction, the positioning assembly 30 is used to align the poles of the battery cell, the identification assembly 40 is slidably connected to the base assembly 20 along the first direction, the identification assembly 40 is used to cooperate with the second base 22 to lock the spacing between adjacent second bases 22, and the first direction and the second direction are perpendicular to each other.

[0036] In actual application, first arrange multiple battery cells in place, then place the positioning assembly 30 above the module, and move the multiple positioning assemblies 30 in sequence to the top of the poles of the corresponding battery cells, then move the identification assembly 40 so that the identification assembly 40 cooperates with the second base 22 to lock the spacing between adjacent second bases 22. At this time, the spacing between the second bases 22 is the spacing between the poles of two adjacent battery cells. The positioning assembly 30 is used to position the aluminum bar in the CCS integrated busbar processing process. When processing CCS integrated busbars of different sizes corresponding to battery cells of different sizes, repeat the above steps so that the positioning assembly 30 is set corresponding to the poles of the battery cells, and then lock the second base 22 by cooperating with the identification assembly 40 and the second base 22. The processing device can be used for the processing of the CCS integrated busbar, without the need to make a mold of the corresponding size or manually measure the spacing between adjacent poles, thereby reducing the manufacturing cost of the CCS integrated busbar, shortening the processing cycle of the CCS integrated busbar, and improving the processing accuracy of the CCS integrated busbar.

[0037] In the embodiment of the present application, the first base 21 is a rectangular frame, the second base 22 is a strip, and the second base 22 is slidably disposed inside the first base 21. The first direction is the length direction of the first base 21, and the second direction is the length direction of the second base 22.

[0038] Further, see Figure 4 The base assembly 20 includes a third base 23 , which is detachably connected to the first base 21 . A first guide groove 25 is formed between the third base 23 and the first base 21 , and the second base 22 is slidably arranged on the first base 21 through the first guide groove 25 .

[0039] In actual use, the second base 22 is mated with a portion of the first guide groove 25 on the first base 21, and then the third base 23 is connected to the first base 21, so that the second base 22 is embedded in the first guide groove 25 formed by the first base 21 and the third base 23. When the second base 22 needs to be removed, the connection between the first base 21 and the third base 23 is released, and the second base 22 can be removed from the first base 21, thereby facilitating the installation and removal of the processing device.

[0040] Further, see Figure 6 and Figure 7 The first base 21 includes a first guide block 212, which extends along the first direction. The first base 21 is provided with a limiting groove 211, which is arranged at one end of the first guide block 212. The third base 23 is provided with a second guide groove 231, which is opened along the first direction. The second guide groove 231 is used to slide with the first guide block 212. The third base 23 includes a limiting portion 234, which is arranged at one end of the second guide groove 231. The limiting portion 234 is used to be plugged into the limiting groove 211.

[0041] In actual use, when connecting the first base 21 and the third base 23, the first guide block 212 is inserted into the second guide groove 231 until the limiting portion 234 is inserted into the limiting groove 211, thereby completing the connection between the first base 21 and the third base 23. The cooperation between the first guide block 212 and the second guide groove 231 enables the first base 21 and the third base 23 to be slidably connected, and the plug-in cooperation between the limiting portion 234 and the limiting groove 211 is used to fix the first base 21 and the third base 23.

[0042] In this embodiment, the cross-sectional shape of the limiting groove 211 is rectangular. In other embodiments, the cross-sectional shape of the limiting groove 211 may also be triangular, trapezoidal, or semicircular.

[0043] Furthermore, magnets are provided on the inner wall of the limiting groove 211 and the limiting portion 234 .

[0044] In actual use, when the limiting portion 234 approaches the limiting slot 211, the attraction between the magnets causes the limiting portion 234 to automatically insert into the limiting slot 211 and abut against the limiting slot 211, thereby securing the limiting portion 234 in the limiting slot 211 and improving the reliability of the plug-in fit between the limiting portion 234 and the limiting slot 211. To disassemble the first base 21 and the third base 23, the operator simply moves the third base 23 with force to allow the limiting portion 234 to pass through the limiting slot 211.

[0045] In this embodiment, the magnet is a ferrite magnet. In other embodiments, the magnet can also be a neodymium iron boron magnet, a samarium cobalt magnet, an alnico magnet, etc.

[0046] Optionally, see Figure 7 , the limiting groove 211 is opened perpendicular to the first direction.

[0047] In practical applications, the limiting groove 211 is opened perpendicular to the first direction, so that the force applied by the limiting portion 234 to the first guide block 212 is a force along the first direction, thereby reducing the wear of the first guide block 212 and improving the service life of the first guide block 212.

[0048] Optionally, refer to Figure 5 The identification component 40 includes a reference portion 41, the third base 23 is provided with a mounting groove 232 and a first through groove 233, the first through groove 233 is provided on the inner wall of the mounting groove 232 and extends along the first direction, the base assembly 20 includes a fourth base 24, the fourth base 24 is inserted into the mounting groove 232, the fourth base 24 is provided with a second through groove 241, the second through groove 241 is connected to the first through groove 233, the reference portion 41 is passed through the first through groove 233 and the second through groove 241, and the reference portion 41 is slidably set on the fourth base 24 through the first through groove 233 and the second through groove 241.

[0049] In actual application, when measuring the spacing between the poles of adjacent battery cells, the fourth base 24 is pulled out of the mounting slot 232, then the fourth base 24 is placed above the battery cell, and the reference portion 41 is moved to a position directly above the pole so that the reference portion 41 is aligned with the pole. The fourth base 24 is then inserted into the mounting slot 232, and the second base 22 is moved to a position aligned with the corresponding reference portion 41 so that the spacing between adjacent second bases 22 is equal to the spacing between adjacent reference portions 41. At this time, the spacing between adjacent second bases 22 is equal to the spacing between adjacent poles, thereby completing the measurement of the spacing between adjacent poles. After the fourth base 24 is removed from the processing device, it is easier for the operator to measure the spacing between the poles, thereby improving measurement efficiency.

[0050] Further, refer to Figure 2 and Figure 5 The second base 22 defines a positioning hole 221 , and one end of the reference portion 41 close to the second base 22 is inserted into the positioning hole 221 .

[0051] In actual application, the fourth base 24 is inserted into the mounting groove 232, and one end of the reference portion 41 is inserted into the positioning hole 221, so as to facilitate the alignment of the second base 22 and the fourth base 24. After one end of the reference portion 41 is inserted into the positioning hole 221, the second base 22 is fixed relative to the fourth base 24 in the plane formed by the first direction and the second direction.

[0052] Further, refer to Figure 5 The identification assembly 40 also includes a handle 42, a gasket 43, a pressing plate 45 and a connecting rod 44. One end of the connecting rod 44 is eccentrically connected to the handle 42, and the other end is connected to the pressing plate 45. The reference portion 41 is arranged on the side of the pressing plate 45 away from the connecting rod 44 and is connected to the pressing plate 45. The gasket 43 is arranged between the handle 42 and the base assembly 20 and is slidably connected to the connecting rod 44. The handle 42 is used to drive the gasket 43 to move, so as to drive the gasket 43 and the pressing plate 45 to cooperate to clamp the fourth base 24.

[0053] In actual use, after the position of the reference portion 41 is determined, the handle 42 is rotated. Since one end of the handle 42 is eccentrically connected to the connecting rod 44, the handle 42 drives the washer 43 toward the pressing plate 45, so that the washer 43 and the pressing plate 45 cooperate to clamp the fourth base 24, thereby locking the reference portion 41 to the second base 22. To release the lock of the reference portion 41, the handle 42 is rotated in the opposite direction to return it to its original position. The washer 43 is no longer subjected to the pressure of the handle 42, thereby releasing the lock of the reference portion 41.

[0054] In this embodiment, one end of the connecting rod 44 is eccentrically connected to the handle 42. In other embodiments, the connecting rod 44 and the handle 42 may be coaxially connected. In this case, the end of the handle 42 connected to the connecting rod 44 has a cam-shaped profile, so that when the handle 42 is rotated, the end of the handle 42 can still drive the gasket 43 to move along the length of the connecting rod 44. In this embodiment, the gasket 43 is made of elastic rubber.

[0055] In other embodiments, the gasket 43 may be an elastic member, made of elastic rubber. One end of the handle 42 compresses the gasket 43, causing it to elastically deform, thereby clamping the fourth base 24 together with the pressure plate 45 to lock the position of the reference portion 41. To unlock the reference portion 41, the handle 42 is rotated to restore the gasket 43's deformation. At this point, the gasket 43 no longer exerts force on the fourth base 24, thereby unlocking the reference portion 41.

[0056] Optionally, refer to Figure 4 The positioning assembly 30 includes a positioning portion 31, and the second base 22 is provided with a third guide groove 222 and a third through groove 223. The third guide groove 222 is opened along the second direction, and the third through groove 223 extends along the second direction through the bottom of the third through groove 223. One end of the positioning portion 31 is slidably connected to the third guide groove 222, and the other end is provided with the third through groove 223.

[0057] In actual application, one second base 22 is connected to two positioning assemblies 30. When measuring the distance between two poles of the same battery cell, the two positioning parts 31 are moved so that the two positioning parts 31 are aligned with the two poles respectively. At this time, the distance between the two positioning parts 31 is the distance between the two poles of the same battery cell.

[0058] Further, refer to Figure 4 The positioning assembly 30 includes a nut 32 , one end of the positioning portion 31 passing through the third through slot 223 passes through the third through slot 223 and is threadedly connected to the nut 32 , and the nut 32 cooperates with the positioning portion 31 to clamp the second base 22 .

[0059] In practice, the positioning portion 31 is sequentially inserted into the third guide slot 222 and the third through slot 223. The nut 32 is then connected to the end of the positioning portion 31 that extends out of the third through slot 223, so that the positioning portion 31 is slidably connected to the second base 22. When measuring the distance between two poles of the same battery cell, the two positioning portions 31 are moved to align with the two poles, and the nut 32 is then rotated so that the nut 32 and the positioning portion 31 jointly clamp the second base 22, thereby locking the positioning portion 31 in place.

[0060] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship and movement status of the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0061] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element through an intervening element.
