[0002] Lithium-ion batteries are widely used in portable electronic devices, electric vehicles, and energy storage systems due to their high energy density and long cycle life. To ensure the safety and reliability of lithium-ion batteries in practical use, in addition to improving their capacity performance, increasingly stringent requirements are being placed on the structural design and assembly process of lithium-ion batteries.

[0003] Currently, lithium-ion batteries typically employ a mating design where grooves are created on the top cover terminals, and corresponding bosses are set on the cell connectors. This mating of the bosses and grooves creates a stable positioning reference between the cell connectors and the terminals. During assembly, the bosses on the cell connectors must be precisely embedded into the grooves on the top cover terminals, and then a reliable connection is achieved through laser welding. In this process, a robotic arm can place the cell connectors on the top cover assembly for welding.

[0004] However, in the current battery cell connector assembly process, it is easy for the battery cell connector to be placed upside down and then ultrasonically welded to the battery cell, resulting in incorrect welding between the battery cell connector and the battery cell.

[0006] Optionally, the receiving portion is a through hole penetrating the positioning base; The battery cell connector positioning device also includes a laser transmitter, a laser receiver, and an alarm component.

[0009] Optionally, the first pusher includes a positioning part and an abutting part connected together. In a direction parallel to the bottom of the positioning groove, the abutting part overlaps with the bearing plate, and the positioning part overlaps with the side wall of the positioning groove. The cell connector includes a connected sheet-like body and the boss, and the sheet-like body can be located in the positioning groove; In the direction perpendicular to the bottom of the positioning groove, the thickness of the positioning part and the thickness of the second propulsion member are both greater than the thickness of the sheet-like body.

[0010] Optionally, the number of positioning slots on the positioning base is two, and the two positioning slots are symmetrically arranged. The positioning base also has an assembly slot located between the two positioning slots. The first pusher includes two first push plates, both of which are located in the assembly groove and are respectively arranged adjacent to the two positioning grooves. The two first push plates move in opposite directions.

The pushing mechanism is used to push the battery cell connector in a direction parallel to the bottom of the positioning groove. The battery cell connector has a boss, and the receiving portion is used to accommodate the boss, with the depth of the positioning groove being less than the height of the boss. Thus, based on the cooperative relationship between the boss and the receiving part, a passive discrimination mechanism can be implemented to determine the placement status of the cell connector: when the cell connector is oriented correctly, the boss is embedded in the receiving part, the overall height is reduced, and the side edge is in full contact with the side wall of the positioning groove, forming an effective barrier, thereby achieving precise positioning under the action of the pushing mechanism; when the cell connector is oriented incorrectly, the boss cannot be embedded in the receiving part, the cell connector is raised, and the side edge is higher than the side wall of the positioning groove, failing to form an effective barrier, and the pushing mechanism can automatically push it out of the positioning groove, completing automatic rejection. Therefore, the placement status can be determined based on the height change during the positioning process of the cell connector, ensuring that only correctly placed cell connectors can enter the subsequent assembly process, thereby avoiding the phenomenon of incorrect welding of cell connectors to cells and improving the structural integrity and electrical reliability of the battery.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0020] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0021] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0022] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a cell connector 10. The lithium-ion battery top cover and the cell connector 10 can be fitted with a groove-boss 101 structure. The engagement of the boss 101 and the groove provides a positioning reference for their assembly. In actual assembly, it is necessary to ensure that the boss 101 of the cell connector 10 is accurately embedded into the groove of the top cover electrode post before laser welding is performed. Currently, this process mainly relies on a robotic arm to complete the picking and placing of the cell connector 10.

[0023] However, in the current assembly process of the cell connector 10, the robotic arm cannot determine the orientation of the connector 10 when picking it up, which can easily lead to the connector 10 being placed upside down. If the incorrectly placed connector 10 is ultrasonically welded to the cell, it will result in incorrect welding between the connector 10 and the cell, causing the entire cell and top cover assembly to be scrapped. Furthermore, if the connector 10 is not precisely positioned, its protrusion 101 is difficult to align perfectly with the groove in the top cover, leading to quality defects such as burn-out spots and incomplete welds during laser welding, which seriously affects the structural integrity and electrical reliability of the battery.

[0024] This utility model embodiment provides a positioning device for a battery cell connector 10, which can solve some or all of the technical problems in the above-mentioned related technologies.

[0025] Please refer to Figure 2 , Figure 3 and Figure 4 , Figure 2 This is a schematic diagram of the structure of a battery cell connector positioning device 20 provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of a positioning base 21 provided in an embodiment of the present invention. Figure 4 This is a schematic diagram of the structure of a battery cell connector provided in an embodiment of the present invention, wherein, Figure 4 The shown cell connector is Figure 1 The diagram shows the back structure of the battery cell connector; the battery cell connector positioning device 20 may include: a positioning base 21 and a propulsion mechanism 22.

[0026] The positioning base 21 is provided with a positioning groove 211, and the bottom of the positioning groove 211 is provided with a receiving part 212. The bottom of the positioning groove 211 can be a flat bottom surface, and the receiving part 212 can be a groove or a through hole provided on the positioning base 21. The groove opening is opened on the bottom of the positioning groove 211, or the opening of the through hole is opened on the bottom of the positioning groove 211.

[0027] The pushing mechanism 22 can be located on one side of the positioning groove 211 and form an accommodating space for placing the battery cell connecting piece between it and the positioning groove 211. The pushing mechanism 22 is used to push the battery cell connecting piece in a direction parallel to the bottom of the positioning groove 211.

[0028] The battery cell connector has a boss, a receiving portion 212 for receiving the boss, and the depth of the positioning groove 211 is less than the height of the boss; for example, the battery cell connector includes a connected sheet-like body 102 and a boss, and the sheet-like body 102 can be located in the positioning groove 211.

[0029] The propulsion mechanism 22 is configured such that, during the process of pushing the battery cell connector, when the boss is housed in the receiving portion 212, the propulsion mechanism 22 pushes the battery cell connector against the side wall of the positioning groove 211 to achieve positioning; when the boss is misaligned with the receiving portion 212, the propulsion mechanism 22 pushes the battery cell connector out of the receiving space. That is, when the boss is not housed in the receiving portion 212, the propulsion mechanism 22 can push the battery cell connector out of the receiving space.

[0030] Please continue to refer to this. Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the working state of a battery cell connector positioning device 20 provided in an embodiment of the present invention. Figure 6 This is a schematic diagram of the working state of another battery cell connector positioning device 20 provided in this embodiment of the utility model. Figure 5 The battery cell connectors are in the correct placement position. Figure 6 In this embodiment of the invention, the battery cell connector is incorrectly positioned. A mechanical structure enables passive screening and precise positioning of the connector. During the use of the battery cell connector positioning device 20, the pushing mechanism 22 provides a continuous and constant thrust to the connector, pushing it to move along the extension direction of the bottom of the positioning groove 211. The final state of the connector (accurate positioning or being pushed out) is determined by its own placement orientation.

[0031] Specifically, such as Figure 5 As shown, when the battery cell connector is placed in the receiving space with the correct orientation, the boss of the battery cell connector will smoothly embed into the receiving portion 212 at the bottom of the positioning groove 211, wherein the depth of the receiving portion 212 is greater than or equal to the height of the boss. Since the depth of the positioning groove 211 is less than the height of the boss, after the boss is inserted into the receiving portion 212, the sheet-like body 102 of the battery cell connector descends to its lowest position. At this time, the side edge of the battery cell connector can fully contact the side wall of the positioning groove 211, so that the side wall of the positioning groove 211 can effectively block the battery cell connector. The thrust of the pushing mechanism 22 can make the battery cell connector fit tightly against the side wall of the positioning groove 211, thereby achieving precise positioning of the correctly oriented battery cell connector.

[0032] like Figure 6As shown, when the battery cell connector is placed in the receiving space with the wrong orientation, the boss cannot fall into the receiving part 212, causing the entire battery cell connector to be raised by the boss and placed at a high position. This makes the side edge of the battery cell connector higher than the side wall of the positioning groove 211, and the side wall of the positioning groove 211 cannot effectively block the battery cell connector. The pushing mechanism 22 can push the battery cell connector out of the receiving space, that is, push the battery cell connector out of the positioning groove 211 of the positioning base 21, thereby automatically rejecting battery cell connectors that do not meet the placement requirements.

[0033] In summary, this utility model embodiment provides a battery cell connector positioning device 20, including a positioning base 21 and a pushing mechanism 22. The positioning base 21 has a positioning groove 211, and the bottom of the positioning groove 211 has a receiving portion 212. The pushing mechanism 22 is located on one side of the positioning groove 211 and together with the positioning groove 211 forms a receiving space for placing the battery cell connector. The pushing mechanism 22 is used to push the battery cell connector in a direction parallel to the bottom of the positioning groove 211. The battery cell connector has a boss, the receiving portion 212 is used to accommodate the boss, and the depth of the positioning groove 211 is less than the height of the boss. Thus, based on the cooperative relationship between the boss and the receiving part 212, a passive discrimination mechanism can be implemented for the placement state of the cell connecting piece: when the cell connecting piece is oriented correctly, the boss is embedded in the receiving part 212, the overall height is reduced, and the side edge is in full contact with the side wall of the positioning groove 211, forming an effective barrier, thereby achieving precise positioning under the action of the pushing mechanism 22; when the cell connecting piece is oriented incorrectly, the boss cannot be embedded in the receiving part 212, the cell connecting piece is raised, and the side edge is higher than the side wall of the positioning groove 211, failing to form an effective barrier, and the pushing mechanism 22 can automatically push it out of the positioning groove 211, completing automatic rejection. Thus, during the positioning process of the cell connecting piece, the placement state can be judged based on its height change, ensuring that only correctly placed cell connecting pieces can enter the subsequent assembly process, thereby avoiding the phenomenon of incorrect welding of cell connecting pieces and cells, and improving the structural integrity and electrical reliability of the battery.

[0034] Please refer to Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of another battery cell connector positioning device 20 provided in this embodiment of the present invention. Figure 8This is a schematic diagram of another battery cell connector positioning device 20 provided in this embodiment of the present invention. In an optional embodiment, the receiving portion 212 can be a through hole penetrating the positioning base 21. The battery cell connector positioning device 20 may also include a laser emitter 23, a laser receiver 24, and an alarm component (not shown in the figure). The laser emitter 23 and the laser receiver 24 are located on both sides of the through hole, and the laser receiver 24 is electrically connected to the alarm component. When the battery cell connector is placed in the receiving space with the correct orientation, the pushing mechanism 22 can push the battery cell connector and achieve precise positioning. In this case, the boss of the battery cell connector is located in the through hole, forming a blockage between the laser emitter 23 and the laser receiver 24. The laser receiver 24 cannot receive the signal emitted by the laser emitter 23, thereby not triggering the alarm component. When the battery cell connector is placed in the receiving space with the wrong orientation, the pushing mechanism 22 can push the battery cell connector out of the positioning slot 211 of the positioning base 21. In this case, the signal emitted by the laser emitter 23 can be transmitted to the laser receiver 24 through the through hole. After receiving the signal, the laser receiver 24 can send a signal to the alarm component, thereby causing the alarm component to emit an alarm signal to remind the operator. For example, the alarm component may include at least one of a sound alarm component, a photoelectric alarm component, and a display alarm component.

[0035] In one exemplary embodiment, the through hole can be a rectangular through hole or a circular through hole. The width of the rectangular through hole is 2mm to 5mm larger than the diameter of the boss, and the diameter of the circular through hole is 2mm to 5mm larger than the diameter of the boss, so that the boss can fall smoothly into the through hole.

[0036] Please refer to Figure 2 In one optional embodiment, the positioning groove 211 may have a first sidewall c1 and a second sidewall c2 that are perpendicularly connected to each other; the pushing mechanism 22 may include a first pushing member 221 and a second pushing member 222, the first pushing member 221 being disposed opposite to the first sidewall c1 and the second pushing member 222 being disposed opposite to the second sidewall c2; the first pushing member 221 is used to push the battery cell connecting piece in the direction toward the first sidewall c1, and the second pushing member 222 is used to push the battery cell connecting piece in the direction toward the second sidewall c2. The pushing direction of the first pusher 221 is perpendicular to the pushing direction of the second pusher 222. When the cell connecting piece is placed in the accommodating space with the correct orientation, the first pusher 221 and the second pusher 222 can push the cell connecting piece to the position that abuts against the first side wall c1 and the second side wall c2 respectively, thereby accurately positioning the cell connecting piece. After the cell connecting piece is accurately positioned, it is picked up by the robotic arm and placed on the top cover assembly. The boss can be completely aligned with the top cover groove, thereby improving the welding quality of the cell connecting piece and thus improving the structural integrity and electrical reliability of the battery.

[0037] Please refer to Figure 2 and Figure 7 In one optional embodiment, the size of the positioning groove 211 matches the size of the cell connecting piece. The positioning base 21 also includes a support plate 213 located below the positioning groove 211, and the receiving portion 212 can be formed in the support plate 213. In the direction parallel to the bottom of the positioning groove 211, the first pusher 221 overlaps with both the support plate 213 and the positioning groove 211, while the second pusher 222 is offset from the support plate 213 and overlaps with the positioning groove 211. Thus, when the first pusher 221 pushes the cell connecting piece, its stroke is limited by the support plate 213; while the second pusher 222, because it is offset from the support plate 213, is not limited by the support plate 213, but is instead limited by the side wall of the positioning groove 211. Therefore, when the battery cell connector is placed facing the wrong direction, the first pusher 221 is blocked by the support plate 213 and cannot push it out of the positioning groove 211, thus only performing the function of positioning the battery cell connector; the second pusher 222, being not restricted by the support plate 213, can position the battery cell connector with the correct orientation and push the battery cell connector with the wrong orientation out of the positioning groove 211. This avoids mutual interference between the two pushers during movement and improves the operational stability of the pusher mechanism 22.

[0038] Please refer to Figure 2 and Figure 7 Optionally, the first pusher 221 includes a connected positioning part b1 and an abutment part b2. In a direction parallel to the bottom of the positioning groove 211, the abutment part b2 overlaps with the support plate 213, and the positioning part b1 overlaps with the side wall of the positioning groove 211. The cell connecting piece includes a connected sheet-like body 102 and a boss. The sheet-like body 102 can be located in the positioning groove 211. In a direction perpendicular to the bottom of the positioning groove 211, the thickness of the positioning part b1 and the thickness of the second pusher 222 are both greater than the thickness of the sheet-like body 102. This thickness design allows the positioning part b1 and the second pusher 222 to effectively contact the side of the sheet-like body 102 during the push-in process, thereby achieving reliable identification and stable push-in of the orientation of the cell connecting piece and avoiding positioning errors caused by insufficient thickness.

[0039] In one exemplary embodiment, the positioning part b1 may be located above the abutting part b2, and the positioning part b1 and the abutting part b2 may be an integral structure. The positioning part b1 may include two positioning blocks, the sheet-like body may have two corners, the two positioning blocks may correspond to the two corners respectively, and the width of the positioning block is greater than the width of the corresponding corner.

[0040] Please refer to Figure 6 and Figure 7In one optional embodiment, the positioning base 21 has two positioning slots 211, which are symmetrically arranged. The positioning base 21 also has an assembly slot 214 located between the two positioning slots 211. The first pusher 221 includes two first push plates 2211, each of which includes a positioning part b1 and an abutment part b2. Both first push plates 2211 are located in the assembly slot 214 and are respectively arranged adjacent to the two positioning slots 211. The two first push plates 2211 move in opposite directions. The second pusher 222 includes two second push plates 2221, which are located on the same side of the two positioning slots 211 and are respectively arranged adjacent to the two positioning slots 211. The two second push plates 2221 move in the same direction. In this way, the cell connector positioning device 20 can simultaneously position two cell connectors, and by installing both first push plates 2211 of the first pusher 221 in the assembly slot 214, the overall compactness of the cell connector positioning device 20 can be improved.

[0041] Please refer to Figure 6 In one optional embodiment, in the arrangement direction parallel to the two positioning slots 211, the shortest distance between the two second push plates 2221 is greater than the width of the assembly slot 214. In the arrangement direction perpendicular to the two positioning slots 211, the size of the second push plate 2221 is greater than or equal to the size of the positioning slot 211. This arrangement avoids interference between the second push plate 2221 and the first push member 221 during operation and ensures that the second push plate 2221 can move stably in the positioning slot 211 when pushing out the cell connecting piece.

[0042] Please refer to Figure 2 and Figure 7 In an optional embodiment, the propulsion mechanism 22 further includes a first driving member 223 and a second driving member 224. The first driving member 223 is connected to the first propulsion member 221 and is used to drive the first propulsion member 221 to move. The second driving member 224 is connected to the second propulsion member 222 and is used to drive the second propulsion member 222 to move. The first driving member 223 may include a first cylinder, which may have two output ends. The two output ends of the first cylinder may be connected to two first push plates 2211 in the first propulsion member 221, respectively, to drive the two first push plates 2211 to move. The second driving member 224 may include a second cylinder, which may be connected to two second push plates 2221 in the second propulsion member 222, respectively, to drive the two second push plates 2221 to move. The two output ends of the first cylinder and the two output ends of the second cylinder can operate independently.

[0043] In an optional embodiment, the propulsion mechanism 22 may further include a pressure control component (not shown), which is electrically connected to the second drive member 224. The pressure control component is used to output a target level to shut down the second drive member 224 when it detects that the thrust of the second propulsion member 222 is greater than a threshold pressure. Since the boss may contact the sidewall of the positioning groove 211 during the process of the second propulsion member 222 pushing the cell connecting piece out of the positioning groove 211, thus generating some resistance to the second propulsion member 222, this resistance is smaller than the resistance generated when the cell connecting piece with the correct orientation abuts against the sidewall of the positioning groove 211. Therefore, the pressure control component can judge the resistance experienced by the second propulsion member 222 to avoid the resistance caused by the boss affecting the operation of the second propulsion member 222.

[0044] The pressure control assembly may include an electrically connected pressure sensor and a comparator. The comparator is electrically connected to the second drive member 224 and is used to detect the thrust generated by the second propeller 222 in real time, and convert the detected pressure signal into an electrical signal output to the comparator. In the comparator, the detected signal is compared with a preset pressure threshold: if the detected pressure is greater than the threshold, it indicates that the second propeller 222 has pushed the cell connecting piece to the position abutting against the side wall of the positioning groove 211, or the second propeller 222 abuts against the side wall of the positioning groove 211, and the comparator outputs a target level (such as a high level) to the second drive member 224 to shut it down, thereby stopping the propulsion action; if the detected pressure does not exceed the threshold, the comparator does not output a target level (or outputs the opposite level), and the second drive member 224 maintains normal operation.

[0045] In one exemplary embodiment, the cell connector positioning device 20 may further include a mounting bracket (not shown in the figure), on which the positioning base 21, the propulsion mechanism 22, the laser emitter 23, the laser receiver 24 and the alarm component can be fixedly mounted. The mounting bracket is used to provide structural support and positioning reference for each component; the mounting bracket may be a steel structure bracket.

Furthermore, it is understood that when an element is referred to as "on top of" another element, it can be directly on the other element, or there may be intermediate elements. Additionally, it is understood that when an element is referred to as "below" another element, it can be directly below the other element, or there may be more than one intermediate element.
