Description

Technical Field

[0001] The utility model relates to the technical field of battery assembly, in particular to a tool. Background Art

[0002] CCS (Cell Contact System, integrated busbar) components are widely used in battery packs of new energy vehicles. Their main function is to integrate the conductive bus, control circuit and other components of the battery pack into one, so as to achieve high-voltage series and parallel connection of battery cells, temperature and voltage sampling, etc.

[0003] The existing CCS assembly consists of an FPC assembly and a connector. The CCS assembly is mounted on an electrical isolation board. The FPC assembly is the signal acquisition component of the battery pack, and the connector is a conductive element used to achieve series and parallel connections between battery cells. The electrical isolation board supports and secures the FPC assembly and connector. Given the increasing integration requirements of battery packs, the demand for battery packs without electrical isolation boards is becoming increasingly apparent. However, because the CCS assembly lacks the support of the electrical isolation board, the connection between the FPC assembly and the connector is easily damaged during the grasping and transfer process, making it difficult to effectively transfer the CCS assembly. Utility Model Content

[0004] The technical problem to be solved by the present invention is that since the CCS component lacks the support of the electrical isolation plate, the connection between the FPC component and the connecting piece is easily damaged during the grabbing and transferring process, making it difficult to effectively complete the transfer of the CCS component.

[0005] In order to solve the above technical problems, the present invention provides a technical solution for tooling:

[0006] The tooling has a first direction, comprising:

[0007] a substrate having a first side surface and a second side surface oppositely disposed along the first direction;

[0008] a pre-installed positioning plate, the pre-installed positioning plate having a third side surface along the first direction toward the first side surface, the third side surface being provided with a receiving groove for receiving a connecting piece;

[0009] A suction and placement component, the suction and placement component comprising a plurality of suction cups, the plurality of suction cups being arranged on the substrate at intervals, and the suction cups having a pressure contact end protruding from the first side surface, the pressure contact end being configured to be able to suction and place the connecting piece;

[0010] A vacuum generator is installed on the second side surface, the vacuum generator is connected to the suction cup, and the vacuum generator is configured to control the pressure contact end to suck and release the connecting piece.

[0011] Furthermore, it also includes a positioning member, which is fixedly arranged on the first side along the first direction, the positioning member is spaced apart from the suction cup, and the positioning member cooperates with the pre-installed positioning plate to limit position.

[0012] Furthermore, a positioning hole is provided on the pre-installed positioning plate, and the positioning hole is spaced apart from the accommodating groove; along the first direction, one end of the positioning member close to the third side surface is inserted into the positioning hole.

[0013] When the tooling is grasped, the positioning piece on the first side is inserted into the positioning hole of the pre-installed positioning plate to ensure the relative position of the substrate and the pre-installed positioning plate is accurate, so that the pressure contact end of the suction cup can accurately absorb the connecting piece.

[0014] Furthermore, along the first direction, the distances between the end faces of the pressure-contact ends of the multiple suction cups close to the third side face and the first side face are equal, and the distance between the end face of the positioning member close to the third side face and the first side face is greater than the distance between the end face of the pressure-contact end of the suction cup and the first side face.

[0015] Not only does it ensure that the pressure contact ends of multiple suction cups can synchronously contact and absorb the connecting pieces of the CCS components, but during the grasping process, the positioning parts first accurately define the relative positions of the substrate and the pre-installed positioning plate to further ensure that the suction cups can reliably absorb the connecting pieces.

[0016] Furthermore, at least two suction cups are provided on the substrate corresponding to each connecting piece, and the at least two suction cups are used to adsorb and cooperate with the same connecting piece. By adsorbing one connecting piece with at least two suction cups, the stability of adsorbing the connecting piece during the grasping process is improved.

[0017] Furthermore, three suction cups are provided on the substrate corresponding to each connecting piece, and the projections of the three suction cups on the first side surface along the first direction do not overlap. The three suction cups on each connecting piece are distributed non-collinearly, thereby providing a reliable planar adsorption effect on the connecting piece.

[0018] Furthermore, the substrate is provided with a plurality of observation holes at intervals, the observation holes corresponding to the intervals between the two connecting pieces along the first direction, and the adsorption position of the suction cup corresponding to the connecting piece can be observed through the observation holes on the substrate.

[0019] Furthermore, the suction and placement assembly is arranged on the outer side of the substrate corresponding to the observation hole, thereby avoiding interference between the observation hole and the suction and placement assembly and taking into account the dual functions of suction and placement, grasping, and observation and positioning.

[0020] Furthermore, a switch is mounted on the substrate, a gas pipeline is connected between the vacuum generator and the suction cup, and the switch is mounted in series on the gas pipeline. The suction cup can be manually controlled to flexibly switch between the suction and release states.

[0021] Furthermore, the base plate is also provided with a handle, and the vacuum generator and the handle are spaced apart on the second side surface. The handle can be used to lift, place, and transfer the base plate and the CCS assembly, ensuring that the CCS assembly can be accurately placed on the battery cell.

[0022] Compared with the prior art, the tooling of the present invention has the following beneficial effects: the tooling adopts a design form of a substrate, a pre-installed positioning plate, a suction and release assembly and a vacuum generator. The substrate has a first side surface and a second side surface arranged opposite to each other along a first direction. The multiple suction cups of the suction and release assembly are arranged on the substrate at intervals, and the suction cups have a pressure contact end protruding from the first side surface. Correspondingly, the pre-installed positioning plate has a third side surface facing the first side surface along the first direction. The third side surface is provided with a receiving groove, and the vacuum generator is installed on the second side surface, and the vacuum generator is connected to the suction cup. The suction and release assembly and the vacuum generator are both installed on the substrate and connected to form a negative pressure path. When the vacuum generator works, the multiple suction cups all produce an adsorption effect.

[0023] During use, the CCS component is placed on the third side of the pre-installed positioning plate, and the connecting piece is positioned and pre-installed in the receiving groove. The pre-installed positioning plate replaces the electrical isolation plate to play a supporting role. The vacuum generator generates negative pressure on the pressure contact end of the suction cup, thereby reliably sucking up the various connecting pieces of the CCS component. When the base plate is used to drive the CCS component to move to the battery cell station, the pressure contact end of the suction cup is controlled to release the connecting piece, and the CCS component falls onto the battery cell under the action of gravity. During the grabbing and transferring process, multiple suction cups have an absorption and release effect on each connecting piece of the CCS component. Even if the CCS component lacks the support of the electrical isolation plate, it will not cause damage to the connection between the FPC board and the connecting piece, ensuring that the transfer of the CCS component can be effectively completed.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0032] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; they can refer to direct connection or indirect connection through an intermediate medium; they can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0033] like Figures 1 to 4As shown, a tooling of an embodiment of the utility model has a first direction Z, comprising: a substrate 1, a pre-installed positioning plate 7, a suction and release assembly 2 and a vacuum generator 3, the substrate 1 having a first side surface 11 and a second side surface 12 arranged opposite to each other along the first direction Z; the pre-installed positioning plate 7 has a third side surface 71 facing the first side surface 11 along the first direction Z, and the third side surface 71 is provided with a receiving groove 70, which is used to accommodate the connecting piece 60.

[0034] The suction and release component 2 includes a plurality of suction cups 20, which are arranged at intervals on the substrate 1, and the suction cups 20 have a pressure contact end 21 protruding from the first side surface 11, and the pressure contact end 21 is configured to be able to suck and release the connecting piece 60; the vacuum generator 3 is installed on the second side surface 12, and the vacuum generator 3 is connected to the suction cups 20, and the vacuum generator 3 is configured to be able to control the pressure contact end 21 to suck and release the connecting piece 60.

[0035] The tooling adopts a design form of a substrate 1, a pre-installed positioning plate 7, a suction and placement assembly 2, and a vacuum generator 3. The substrate 1 has a first side surface 11 and a second side surface 12 arranged opposite to each other along a first direction Z. The multiple suction cups 20 of the suction and placement assembly 2 are arranged on the substrate 1 at intervals, and the suction cups 20 have a pressure contact end 21 protruding from the first side surface 11. Correspondingly, the pre-installed positioning plate 7 has a third side surface 71 facing the first side surface 11 along the first direction Z, and the third side surface 71 has a receiving groove 70. The vacuum generator 3 is installed on the second side surface 12 and is connected to the suction cups 20. The suction and placement assembly 2 and the vacuum generator 3 are both installed on the substrate 1 and connected to form a negative pressure path. When the vacuum generator 3 works, the multiple suction cups 20 all produce an adsorption effect.

[0036] During use, the CCS assembly 6 (FPC board 61 and connector 60) is placed on the third side 71 of the pre-installed positioning plate 7, with the connector 60 positioned and pre-installed in the receiving groove 70. The pre-installed positioning plate 7 replaces the electrical isolation plate to provide support. Before the vacuum generator 3 operates, the FPC board 61 and connector 60 on the pre-installed positioning plate 7 are first welded. The vacuum generator 3 then generates negative pressure on the pressure contact end 20 of the suction cup 2, thereby reliably sucking each connector 60 of the CCS assembly. When the CCS assembly 6 is moved to the battery cell station using the base plate 1, the pressure contact end 21 of the suction cup 20 is controlled to release the connector 60, and the CCS assembly 6 is placed onto the battery cell under the action of gravity. During the grabbing and transfer process, the multiple suction cups 20 simultaneously absorb and release each connector 60 of the CCS assembly 6. Even if the CCS assembly 6 lacks the support of the electrical isolation plate, the connection between the FPC board 61 and the connector 60 will not be damaged, ensuring that the CCS assembly 6 can be effectively transferred.

[0037] It should be noted that the tooling also has a second direction X and a third direction Y. The first direction Z, the second direction X and the third direction Y intersect with each other. The first direction Z is arranged perpendicular to the direction of the substrate 1. The substrate 1 has two long sides 13 and two wide sides 14 arranged in parallel. The long side 13 of the substrate 1 extends along the second direction X, and the wide side 14 of the substrate 1 extends along the third direction Y.

[0038] In this embodiment, the tooling further includes a positioning member 4, which is fixedly disposed on the first side surface 11 along the first direction Z. The positioning member 4 is spaced apart from the suction cup 20 and cooperates with the pre-installed positioning plate 7 to limit position. Specifically, the pre-installed positioning plate 7 is provided with a positioning hole 72, which is spaced apart from the receiving groove 70. Along the first direction Z, the end of the positioning member 4 closest to the third side surface 71 is inserted into the positioning hole 72. When the tooling is grasping, the positioning member 4 on the first side surface 11 is inserted into the positioning hole 72 of the pre-installed positioning plate 7, ensuring the accurate relative position of the substrate 1 and the pre-installed positioning plate 7, thereby allowing the pressure contact end 21 of the suction cup 20 to accurately absorb the connecting piece 60.

[0039] Furthermore, along the first direction Z, the distance L1 between the end surface of the pressure-contacting end of each of the multiple suction cups, located near the third side surface, and the first side surface is equal, ensuring that the pressure-contacting ends 21 of each of the multiple suction cups 20 can synchronously contact and absorb the connecting piece 60 of the CCS assembly 6. The distance L2 between the end surface of the positioning member, located near the third side surface, and the first side surface is greater than the distance L1 between the end surface of the pressure-contacting end of the suction cup and the first side surface. During the grasping process, the positioning member 4 first accurately defines the relative position of the substrate 1 and the pre-assembled positioning plate 7 to further ensure that the suction cups 20 can reliably absorb the connecting piece 60.

[0040] As a further preferred embodiment, four positioning members 4 are provided, and the four positioning members 4 are distributed at the top corners of the substrate 1, ensuring the precise positioning of the substrate 1 relative to the pre-installed positioning plate 7. At least two suction cups 20 are provided on the substrate 1 corresponding to each connecting piece 60, and at least two suction cups 20 are used to adsorb and cooperate with the same connecting piece 60. By adsorbing one connecting piece 60 with at least two suction cups 20, the stability of adsorbing the connecting piece 60 during the grasping process is improved. Specifically, three suction cups 20 are provided on the substrate 1 corresponding to each connecting piece 60, and the projections of the three suction cups 20 on the first side surface 11 along the first direction Z do not overlap. The three suction cups 20 of each connecting piece 60 are distributed in a non-collinear manner at three points, so that a reliable planar adsorption effect can be produced on the connecting piece 60.

[0041] The substrate 1 is provided with a plurality of observation holes 10 at intervals. These observation holes 10 correspond to the intervals between the two connecting pieces 60 along the first direction Z. Through these observation holes 10, the suction position of the suction cup 20 relative to the connecting piece 60 can be observed. The suction and placement assembly 2 is positioned outside the observation holes 10 on the substrate 1, preventing interference between the observation holes 10 and the suction and placement assembly 2, thereby achieving both suction and placement, gripping, and observation and positioning.

[0042] In addition, a switch 5 is mounted on the substrate 1. A gas line 22 is connected between the vacuum generator 3 and the suction cup 20. The switch 5 is installed in series with the gas line 22, allowing manual control of the suction cup 20 to flexibly switch between the suction and release states. Furthermore, a handle 15 is mounted on the substrate 1. The vacuum generator 3 and the handle 15 are spaced apart on the second side surface 12. The handle 15 allows the substrate 1 and the CCS assembly 6 to be lifted, lowered, and transferred, ensuring that the CCS assembly 6 can be accurately placed on the battery cell.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
