[0002] After the lithium battery is manufactured, it needs to be tested for airtightness. The current sealing fixture can only manually seal the explosion-proof valve, which is inconvenient to operate and affects the detection efficiency. Utility Model Content

[0003] The main purpose of this application is to propose an explosion-proof valve sealing fixture and sealing equipment, aiming to at least improve the technical problem in the related art that manual sealing of the explosion-proof valve during the gas-tightness test of lithium batteries is inconvenient to operate and reduces the detection efficiency.

[0004] To achieve the above-mentioned purpose, according to some embodiments of the present application, the present application provides an explosion-proof valve sealing clamp, comprising a base, a contoured guide installed on the base, a clamping assembly and a sealing assembly, the clamping assembly comprising a clamping drive and a clamping member connected to the clamping drive, the sealing assembly comprising a sealing drive and a sealing member connected to the sealing drive, the sealing member being provided with a sealing surface, the contoured guide being provided with a contoured hole for accommodating the explosion-proof valve, the clamping member being used to clamp the explosion-proof valve, and the sealing drive being used to drive the sealing member to move toward the explosion-proof valve so as to abut the sealing surface against the explosion-proof valve.

[0005] A contoured guide is provided to guide and initially position the explosion-proof valve. A clamping member then clamps and secures the valve. Finally, a sealing driver drives the seal to engage the valve, sealing the gap in the valve and meeting the battery's airtightness test requirements. This embodiment enables automatic sealing of the explosion-proof valve, reduces manual labor, and improves testing efficiency.

[0006] In some embodiments, the contoured guide member is provided with a waist-shaped hole, the clamping member includes a clamping portion and a clamping claw connected to the clamping portion, the clamping portion is connected to the clamping drive member, the clamping claw can move along the extension direction of the waist-shaped hole, and the clamping claw is used to clamp the explosion-proof valve.

[0007] By setting a waist-shaped hole on the contoured guide, the clamping claw can pass through the waist-shaped hole and move along the extension direction of the waist-shaped hole, so that after the explosion-proof valve enters the contoured hole, the clamping claw can be driven by the clamping driving member to move to the position of clamping the explosion-proof valve, making it convenient to clamp the explosion-proof valve by the clamping claw and fix the explosion-proof valve.

[0008] In some embodiments, there are two waist-shaped holes and two clamping jaws, which are arranged in a one-to-one correspondence, and the two clamping jaws are respectively arranged on two opposite sides of the clamping portion.

[0009] By setting the number of waist-shaped holes to two, two clamping jaws can be set to clamp the explosion-proof valve from both sides, which is beneficial to clamping the explosion-proof valve and facilitates subsequent testing.

[0010] In some embodiments, the clamping drive drives the clamping member to move in a first direction, the sealing drive drives the sealing member to move in a second direction, the first direction is the extension direction of the waist-shaped hole, and the first direction is perpendicular to the second direction.

[0011] By setting the clamping drive to move in a first direction to clamp the explosion-proof valve, and the sealing drive to move in a second direction to drive the sealing member to abut against the explosion-proof valve, the first direction and the second direction are perpendicular, which can achieve clamping and sealing of the explosion-proof valve from two directions. Compared with setting in the same direction, the interference between the sealing assembly and the clamping assembly can be reduced.

[0012] In some embodiments, the base is provided with a mounting groove and a communication hole through which the sealing member passes, the clamping portion is movably mounted in the mounting groove, and the clamping portion is provided with a relief hole at a position corresponding to the communication hole.

[0013] The mounting groove is an open upward groove, and the clamping portion can move in the opening direction of the mounting groove under the drive of the clamping drive, that is, in the vertical direction, thereby driving the clamping jaw to move in the vertical direction. Since the sealing member needs to extend into the profiling hole to abut against the explosion-proof valve, a communication hole is provided on the base, and a relief hole is provided at a position corresponding to the clamping portion. The relief hole and the communication hole are both through holes for the sealing member to pass through, which reduces the possibility of interference between the sealing member and the base and the clamping portion during movement.

[0014] By setting the mounting groove to provide relief space for the vertical movement of the connecting portion, and by setting the communication hole and the relief hole to provide relief space for the movement of the sealing member, the possibility of interference between the sealing member and the clamping portion and other components can be reduced.

[0015] In some embodiments, the profiling hole is a through hole, the shape of the profiling hole is matched with the shape of the outer contour of the explosion-proof valve, and the sealing member extends into the profiling hole to abut the sealing surface against the explosion-proof valve.

[0016] By setting the profiling hole as a through hole, the explosion-proof valve and the sealing member can enter from both ends of the profiling hole, respectively, to achieve preliminary positioning and sealing plugging of the explosion-proof valve.

[0017] In some embodiments, the contoured guide member includes a guide block and a substrate, the substrate is connected to the base, the contoured hole is provided on the substrate, the guide block is provided on the side of the substrate away from the sealing drive member, and the guide block is provided on the periphery of the contoured hole, and the guide block is provided with a guide surface extending toward the contoured hole.

[0018] By setting the guide block, the explosion-proof valve can be guided into the contoured hole and a certain position deviation can be accommodated, so that the explosion-proof valve sealing fixture has a certain correction function and improves the robustness of the fixture.

[0019] In some embodiments, the sealing member includes a connecting rod, a shell and a sealing ring, the two ends of the connecting rod are respectively connected to the sealing drive member and the shell, the shell is provided with a accommodating cavity, the accommodating cavity is provided with an opening facing away from the connecting rod, a circular ring is provided in the accommodating cavity, an annular groove is provided between the circular ring and the inner circumferential wall of the shell, the sealing ring is provided in the annular groove, and the side of the sealing ring facing the opening is the sealing surface.

[0020] By setting an annular groove between the outer shell and the circular ring for installing the sealing ring, and the sealing ring is set toward the opening of the accommodating cavity, when the outer shell moves toward the explosion-proof valve, the sealing ring can abut against the gap surface of the explosion-proof valve. The gap surface refers to the side of the explosion-proof valve with a gap. The sealing ring plays the role of sealing the explosion-proof valve.

[0021] According to some embodiments of the present application, the present application provides a sealing device, which includes a connecting arm and the explosion-proof valve sealing clamp as described above, and the connecting arm is connected to the base to drive the base to move.

[0022] By setting a connecting arm to connect with the base, the explosion-proof sealing fixture can be driven to move to the required position, eliminating the need for manual material handling, reducing labor intensity and improving detection efficiency.

[0023] In some embodiments, the base includes two side panels arranged opposite to each other, each side panel is provided with a connecting hole, the connecting arm includes two sub-arms, the two sub-arms and the two connecting holes are arranged in a one-to-one correspondence, and the sub-arms and the connecting holes are connected by fasteners.

[0055] At present, from the development of market situation, the application of power battery is more and more widely. Power battery is not only applied to energy storage power supply system of water power, fire power, wind power and solar power station, but also widely used in electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment and aerospace and other fields. With the continuous expansion of the application field of power battery, the demand of its market is also increasing.

[0056] After the battery or battery pack is completed, it needs to be tested for air tightness. The air tightness test needs to use a packaging clamp to block the explosion-proof valve. The current method is generally manual blocking, and the explosion-proof valve is blocked well after repeated adjustment for several times. The applicant found that due to the different positions of incoming materials and the differences between battery products, there is a small deviation in the position of the explosion-proof valve that needs to be blocked, so manual adjustment is needed. Through the observation of the operator's eyes, the deviation is adjusted, and the explosion-proof valve can be accurately blocked.

[0057] In an embodiment of the present application, an explosion-proof valve sealing fixture comprises a base, a contoured guide mounted on the base, a clamping assembly, and a sealing assembly. The clamping assembly comprises a clamping driver and a clamping member connected to the clamping driver. The sealing assembly comprises a sealing driver and a sealing member connected to the sealing driver. The sealing member is provided with a sealing surface. The contoured guide is provided with a contoured hole for accommodating the explosion-proof valve. The explosion-proof valve herein refers to the explosion-proof valve on a battery. When sealing the explosion-proof valve, the explosion-proof valve is first installed in the contoured hole via the contoured guide. The contoured guide has a guiding function. The shape of the contoured hole matches the shape of the outer contour of the explosion-proof valve. In this way, the contoured guide can guide the explosion-proof valve to adjust the position of the explosion-proof valve to a certain extent even if there is a slight position deviation. After being installed in the contoured hole, the explosion-proof valve is clamped and fixed by the clamping member. Finally, the sealing driver drives the seal toward the explosion-proof valve, and the sealing surface abuts the explosion-proof valve to seal the gap in the explosion-proof valve, thereby achieving a sealing effect. This embodiment can realize automatic blocking of the explosion-proof valve without manual adjustment, thereby improving detection efficiency.

[0058] Please refer to Figure 1 , Figure 1 A schematic structural diagram of a vehicle 1000 provided for some embodiments of the present application. The electrical device may be the vehicle 1000, and the vehicle 1000 may be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc. A battery 100 is provided inside the vehicle 1000, and the battery 100 may be provided at the bottom, head, or tail of the vehicle 1000. The battery 100 may be used to power the vehicle 1000, for example, the battery 100 may serve as an operating power source for the vehicle 1000. The vehicle 1000 may further include a controller 200 and a motor 300, and the controller 200 is used to control the battery 100 to power the motor 300, for example, for starting, navigating, and operating power requirements of the vehicle 1000 during driving.

[0059] In some embodiments of the present application, the battery 100 can serve not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0060] Please refer to Figure 2 , Figure 2This is a schematic diagram of the exploded structure of a battery 100 provided in some embodiments of the present application. The battery 100 includes a housing 10 and battery cells 20, with the battery cells 20 housed within the housing 10. The housing 10 provides storage space for the battery cells 20 and can have various structures. In some embodiments, the housing 10 can include a first portion 11 and a second portion 12, which overlap each other and together define a storage space for the battery cells 20. The second portion 12 can be a hollow structure with one end open. The first portion 11 can be a plate-like structure, with the first portion 11 overlapping the open side of the second portion 12, so that the first portion 11 and the second portion 12 together define a storage space. Alternatively, the first portion 11 and the second portion 12 can each be a hollow structure with one end open, with the open side of the first portion 11 overlapping the open side of the second portion 12. Of course, the housing 10 formed by the first portion 11 and the second portion 12 can have various shapes, such as a cylinder or a rectangular parallelepiped.

A hybrid connection refers to a combination of series and parallel connections among the multiple cells 20. The multiple cells 20 may be directly connected in series, in parallel, or in a hybrid connection, and then the entire battery 20 may be housed within the housing 10. Alternatively, the battery 100 may be constructed by first connecting multiple cells 20 in series, in parallel, or in a hybrid connection to form a battery module, which is then connected in series, in parallel, or in a hybrid connection to form a single unit housed within the housing 10.

[0063] The present application provides an explosion-proof valve blocking fixture 1 for blocking an explosion-proof valve 30 of a battery 100 .

[0064] Please refer to Figures 3 to 5 According to some embodiments of the present application, the present application provides an explosion-proof valve sealing fixture 1, comprising a base 2, a contoured guide 3 installed on the base 2, a clamping assembly and a sealing assembly, the clamping assembly comprising a clamping drive 4 and a clamping member 5 connected to the clamping drive 4, the sealing assembly comprising a sealing drive 6 and a sealing member 7 connected to the sealing drive 6, the sealing member 7 is provided with a sealing surface 731, the contoured guide 3 is provided with a contoured hole 311 for accommodating the explosion-proof valve 30, the clamping member 5 is used to clamp the explosion-proof valve 30, and the sealing drive 6 is used to drive the sealing member 7 to move toward the explosion-proof valve 30 to abut the sealing surface 731 against the explosion-proof valve 30.

[0065] The base 2 refers to the base portion of the explosion-proof valve sealing fixture 1 and is used to provide an installation location for the contoured guide 3, the clamping assembly, and the sealing assembly. The contoured guide 3 is configured to match the outer contour of the explosion-proof valve 30. Specifically, the contoured hole 311 is shaped to match the shape of the explosion-proof valve 30, facilitating the subsequent clamping and installation of the explosion-proof valve 30. The contoured guide 3 also provides a guiding function, guiding the explosion-proof valve 30 as it extends into the contoured hole 311. This allows for minor positional deviations to be adjusted using the contoured guide 3, providing a certain degree of correction. Furthermore, after the explosion-proof valve 30 is installed in the contoured hole 311, the clamping driver 4 drives the clamping member 5 toward the explosion-proof valve 30. The clamping member 5 cooperates with the structure on the explosion-proof valve 30 to clamp the explosion-proof valve 30, securing it. After the explosion-proof valve 30 is fixed, the sealing member 7 is driven by the sealing driving member 6 to move toward the explosion-proof valve 30, so that the sealing surface 731 of the sealing member 7 abuts against the explosion-proof valve 30, specifically against the surface of the explosion-proof valve 30 with a gap, Figure 11 The explosion-proof valve 30 is provided with a groove 301 for the clamping member 5 to clamp. The surface with the gap can be defined as the abutment surface 302, which seals the explosion-proof valve 30 and meets the requirements of the airtightness test of the battery 100. Specifically, the sealing drive member 6 and the clamping drive member 4 can be a cylinder or a motor.

[0066] The contoured guide member 3 is provided to guide and initially position the explosion-proof valve 30. The clamping member 5 then clamps and secures the explosion-proof valve 30. Finally, the sealing member 7 is driven by the sealing driver 6 to abut against the explosion-proof valve 30, thereby blocking the gap in the explosion-proof valve 30 and meeting the airtightness test requirements of the battery 100. This embodiment can achieve automatic sealing of the explosion-proof valve 30, reduce manual operations, and improve detection efficiency.

[0067] Please refer to Figure 6 and Figure 7 In some embodiments, the contoured guide member 3 is provided with a waist-shaped hole 312, the clamping member 5 includes a clamping portion 51 and a clamping claw 52 connected to the clamping portion 51, the clamping portion 51 is connected to the clamping drive member 4, the clamping claw 52 can move along the extension direction of the waist-shaped hole 312, and the clamping claw 52 is used to clamp the explosion-proof valve 30.

[0068] The waist-shaped hole 312 is a long strip hole, and the extension direction of the waist-shaped hole 312 can be Figure 4In the direction indicated by Y, i.e., the vertical direction, the clamping member 5 includes a clamping portion 51 and a clamping claw 52. The clamping portion 51 can be a plate-shaped member. The driving member drives the clamping portion 51 to move and thereby drives the clamping claw 52 to move. Since the waist-shaped hole 312 is provided, the clamping claw 52 can move along the extension direction of the waist-shaped hole 312 without interfering with the contoured guide member 3. The clamping claw 52 includes an extended end, and the explosion-proof valve 30 is provided with a structure adapted to the shape of the clamping claw 52, ​​for example Figure 11 As shown in FIG, the explosion-proof valve 30 is provided with a groove 301 that matches the protruding end.

[0069] By setting a waist-shaped hole 312 on the contoured guide 3, the clamping jaw 52 can pass through the waist-shaped hole 312 and move along the extension direction of the waist-shaped hole 312, so that after the explosion-proof valve 30 enters the contoured hole 311, the clamping driving member 4 can drive the clamping jaw 52 to move to the position of clamping the explosion-proof valve 30, making it convenient to clamp the explosion-proof valve 30 by the clamping jaw 52, ​​thereby fixing the explosion-proof valve 30.

[0070] Please refer to Figure 5 and Figure 6 In some embodiments, the contoured hole 311 is a through hole, and the shape of the contoured hole 311 is adapted to the shape of the outer contour of the explosion-proof valve 30 . The sealing member 7 extends into the contoured hole 311 to abut the sealing surface 731 against the explosion-proof valve 30 .

[0071] The profiling hole 311 is a through hole. The explosion-proof valve 30 extends into the profiling hole 311 from one end of the profiling hole 311. The profiling hole 311 can play a preliminary positioning role, and the sealing member 7 extends into the profiling hole 311 from the other end of the profiling hole 311. The sealing surface 731 on the sealing member 7 abuts against the explosion-proof valve 30, specifically the abutting surface 302 of the explosion-proof valve 30, to block the gap on the abutting surface 302 of the explosion-proof valve 30 to meet the requirements of air tightness testing.

[0072] By setting the contoured hole 311 as a through hole, the explosion-proof valve 30 and the sealing member 7 can enter from both ends of the contoured hole 311 respectively, thereby achieving preliminary positioning and sealing of the explosion-proof valve 30.

[0073] Please refer to Figure 6 In some embodiments, the contoured guide member 3 includes a guide block 32 and a substrate 31. The substrate 31 is connected to the base 2. A contoured hole 311 is provided on the substrate 31. The guide block 32 is provided on the side of the substrate 31 away from the sealing driver 6, and the guide block 32 is provided on the outer periphery of the contoured hole 311. The guide block 32 is provided with a guide surface 321 extending toward the contoured hole 311.

[0074] The guide block 32 is disposed around the outer periphery of the contoured hole 311. The guide block 32 is actually provided with a guide hole, and the cross-sectional dimensions of the guide hole vary, specifically gradually decreasing from the side away from the contoured hole 311 to the side closer to the contoured hole 311. The dimension on the side closer to the contoured hole 311 is smaller than the dimension on the side away from the contoured hole 311. When the cross-section of the guide hole is circular, this dimension can be the diameter of the guide hole cross section, and the dimension on the side closer to the contoured hole 311 is no smaller than the dimension of the contoured hole 311. Specifically, the guide surface 321 can be a smooth curved surface, such as a conical surface. This design allows the guide block 32 to guide the explosion-proof valve 30 into the contoured hole 311 when there is a slight deviation in position between the explosion-proof valve 30 and the contoured hole 311, thus accommodating certain positional deviations.

[0075] By providing the guide block 32 , the explosion-proof valve 30 can be guided into the contoured hole 311 , and a certain position deviation can be accommodated, so that the explosion-proof valve blocking fixture 1 has a certain deviation correction function, thereby improving the robustness of the fixture.

[0076] Please refer to Figure 6 and Figure 7 In some embodiments, the number of waist-shaped holes 312 and the number of clamping jaws 52 are both two and they are arranged in a one-to-one correspondence, and the two clamping jaws 52 are respectively arranged on two opposite sides of the clamping portion 51.

[0077] There are two clamping jaws 52, which are respectively arranged on the opposite sides of the clamping portion 51. When clamping, they also clamp the opposite sides of the explosion-proof valve 30, which is conducive to clamping the explosion-proof valve 30. Specifically, a groove 301 is provided on each of the two opposite sides of the explosion-proof valve 30 in the horizontal direction, and the protruding end of the clamping jaw 52 extends into the groove 301 to clamp the explosion-proof valve 30. The two waist-shaped holes 312 are respectively located on the opposite sides of the profiling hole 311, specifically on the opposite sides in the horizontal direction. In this way, when the clamping jaw 52 moves up and down in the vertical direction, it can clamp the grooves 301 on both sides of the explosion-proof valve 30 at the same time. The horizontal direction here refers to Figure 4 The direction indicated by X.

[0078] By setting the number of waist-shaped holes 312 to two, two clamping jaws 52 can be provided to clamp the explosion-proof valve 30 from both sides at the same time, which is conducive to clamping the explosion-proof valve 30 and facilitates subsequent testing.

[0079] Please refer to Figure 4 、 Figure 6 and Figure 7 In some embodiments, the clamping driver 4 drives the clamping member 5 to move along a first direction, and the sealing driver 6 drives the sealing member 7 to move along a second direction. The first direction is the extension direction of the waist-shaped hole 312, and the first direction is perpendicular to the second direction.

[0080] The first direction here can be the vertical direction, that is, Figure 4 The direction indicated by Y is also the extension direction of the waist-shaped hole 312. The second direction is a direction on the horizontal plane. Figure 4 The direction perpendicular to the paper is the central axis direction of the profiling hole 311, which is also the moving direction of the sealing driver 6 driving the sealing member 7. When the explosion-proof valve 30 enters the profiling hole 311, the clamping driver 4 drives the clamping member 5 to move in the vertical direction to clamp the explosion-proof valve 30.

[0081] By setting the clamping drive 4 to move along the first direction to clamp the explosion-proof valve 30, and the sealing drive 6 to move along the second direction to drive the sealing member 7 to abut against the explosion-proof valve 30, the first direction and the second direction are set perpendicularly, and the explosion-proof valve 30 can be clamped and sealed from two directions respectively. Compared with setting them in the same direction, the possibility of interference between the sealing component and the clamping component can be reduced, and the structural layout is more compact.

[0082] Please refer to Figure 7 and Figure 8 In some embodiments, the base 2 is provided with a mounting groove 21 and a connecting hole 22 for the seal 7 to pass through, the clamping portion 51 is movably installed in the mounting groove 21, and the clamping portion 51 is provided with an avoidance hole 511 at a position corresponding to the connecting hole 22.

[0083] The mounting groove 21 is a groove body with an opening facing upward. The clamping portion 51 can move along the opening direction of the mounting groove 21, that is, in the vertical direction, under the drive of the clamping driving member 4, thereby driving the clamping jaw 52 to move in the vertical direction. At the same time, since the sealing member 7 needs to extend into the contoured hole 311 and abut against the explosion-proof valve 30, a connecting hole 22 must be provided on the base 2, and an avoidance hole 511 must be provided at the corresponding position of the clamping portion 51. The avoidance hole 511 and the connecting hole 22 are both through holes for the sealing member 7 to pass through, thereby reducing the possibility of interference between the sealing member 7 and the base 2 and the clamping portion 51 during movement.

[0084] By setting the mounting groove 21 to provide an escape space for the vertical movement of the connecting part, and by setting the connecting hole 22 and the escape hole 511 to provide an escape space for the movement of the seal 7, the possibility of interference between the seal 7 and the clamping part 51 and other components can be reduced.

[0085] Please refer to Figure 9 and Figure 10In some embodiments, the sealing member 7 includes a connecting rod, a shell 72 and a sealing ring 73. The two ends of the connecting rod are respectively connected to the sealing driving member 6 and the shell 72. The shell 72 is provided with a accommodating cavity 74.

In this way, an annular groove 75 is formed between the circular ring 71 and the outer shell 72. The annular groove 75 provides a position for the installation of the sealing ring 73, which is clamped in the annular groove 75. The side of the sealing ring 73 facing the opening is a sealing surface 731. The sealing surface 731 abuts against the explosion-proof valve 30 to block the explosion-proof valve 30. Specifically, the sealing ring 73 here can be an elastic member, which is firmly installed in the annular groove 75 by extrusion deformation. At the same time, it can be deformed when abutting against the abutting surface 302 with a gap of the explosion-proof valve 30, making the abutment tighter, which is conducive to improving the sealing performance.

[0087] By providing an annular groove 75 between the housing 72 and the ring 71 for installing the sealing ring 73, and the sealing ring 73 is arranged toward the opening of the accommodating chamber 74, when the housing 72 moves toward the explosion-proof valve 30, the sealing ring 73 can abut against the abutting surface 302 of the explosion-proof valve 30. The abutting surface 302 refers to the side of the explosion-proof valve 30 with a gap, and the sealing ring 73 plays a role in sealing the explosion-proof valve 30.
