Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a negative pressure cup assembly and a battery negative pressure suction device. Background Technology

[0002] In the battery production process, the negative pressure cup in the formation process usually needs to be changed in number of channels to meet the production requirements of different batteries.

[0003] Changing the number of channels requires disassembling the negative pressure cup. However, in related technologies, the negative pressure cup is usually directly fixed to the mounting plate with bolts. This fixing method makes disassembly of the negative pressure cup require removing a large number of bolts, which is cumbersome, time-consuming, and difficult. Utility Model Content

[0004] To address the aforementioned shortcomings in related technologies, this application provides a negative pressure cup assembly and a battery-assisted negative pressure device to solve the problems of cumbersome operation, time-consuming process, and high operational difficulty when disassembling the negative pressure cup in related technologies.

[0005] To address the aforementioned technical problems, in a first aspect, this application provides a negative pressure cup assembly, which is used to be mounted on a mounting component. The mounting component has a mounting hole, which is a non-circular hole. The negative pressure cup assembly includes:

[0006] A negative pressure cup includes a cup body and a return pipe, wherein the return pipe is connected to the cup body and is used to pass through the mounting hole;

[0007] A first limiting member is disposed on the return pipe and is used to abut against a first side of the mounting member in a first direction, the first direction extending along the axial direction of the return pipe;

[0008] The second limiting member is disposed on the side of the first limiting member away from the cup body, and is rotatably disposed on the return pipe around the axis of the return pipe. The second limiting member passes through the first station and the second station in sequence during the rotation process.

[0009] An elastic snap-fit ​​structure is provided on at least one of the first limiting member and the return pipe;

[0010] When the second limiting member is located at the first work station, the portion of the projection of the second limiting member in the first direction is outside the mounting hole, so that the second limiting member and the second side of the mounting member in the first direction abut against each other, and the elastic snap-fit ​​structure engages with the mounting member in the first direction, wherein the first side and the second side of the mounting member are arranged opposite to each other in the first direction;

[0011] When the second limiting member is located at the second work station, the projection of the second limiting member in the first direction is located in the mounting hole, so that the second limiting member can pass through the mounting hole along the first direction, and the elastic snap-fit ​​structure can release the snap-fit ​​engagement.

[0012] In one possible implementation of the first aspect, the elastic snap-fit ​​structure includes an elastic claw, which is disposed on the first limiting member;

[0013] When the second limiting member is located at the first station, the elastic claw is used to abut against the second side of the mounting member so that the elastic locking structure engages with the mounting member.

[0014] The elastic claw is configured to elastically deform under pressure from the wall of the mounting hole, so as to release the locking engagement when the second limiting member passes through the mounting hole in the first direction.

[0015] In one possible implementation of the first aspect, multiple elastic claws are provided, and the multiple elastic claws are spaced apart in the circumferential direction of the return pipe.

[0016] In one possible implementation of the first aspect, the second limiting member is also movably disposed on the return pipe along the first direction;

[0017] An elastic element is provided between the second limiting member and the return pipe, and the elastic element is used to apply elastic force to the second limiting member in the direction from the second side of the mounting member to the first side of the mounting member.

[0018] In one possible implementation of the first aspect, a nesting groove is provided on the side of the first limiting member near the second limiting member, and a nesting protrusion is provided on the side of the second limiting member near the first limiting member. The nesting protrusion is movably disposed in the nesting groove along the first direction and rotatably disposed in the nesting groove around the axial direction of the return pipe.

[0019] In one possible implementation of the first aspect, a mounting groove is provided on the side of the second limiting member opposite to the first limiting member, the mounting groove extending axially along the return pipe into the nested protrusion, and at least a portion of the elastic member is disposed within the mounting groove.

[0020] In one possible implementation of the first aspect, one of the first limiting member and the second limiting member is provided with a pin, and the other is provided with a pin hole, wherein the pin is used to be inserted into the pin hole when the second limiting member is located at the first station.

[0021] Secondly, this application also provides a battery suction negative pressure device, which includes:

[0022] The mounting component is provided with a plurality of mounting holes, which are non-circular holes;

[0023] The negative pressure cup assembly according to any one of the first aspects is provided in a plurality of negative pressure cup assemblies, and the plurality of negative pressure cup assemblies are arranged in a one-to-one correspondence with the plurality of mounting holes;

[0024] A negative pressure source is connected to the negative pressure cups in the plurality of negative pressure cup assemblies and is used to create negative pressure inside the negative pressure cups.

[0025] In a possible implementation of the second aspect, the mounting hole is a strip-shaped hole, and the mounting hole has a first length and a first width;

[0026] The second limiting member is a strip-shaped member, and the second limiting member has a second length and a second width, the second length is less than the first length and greater than the first width, and the second width is less than the first width;

[0027] When the second limiting member is located at the first station, the second length and the first width extend in the same direction; when the second limiting member is located at the second station, the second length and the first length extend in the same direction, and the second width and the first width extend in the same direction; wherein, the first station rotates 90° relative to the second station.

[0028] In a possible implementation of the second aspect, the plurality of mounting holes are arranged at intervals in the second direction;

[0029] On the side of the mounting member near the first limiting member and / or the side near the second limiting member, a plurality of positioning grooves are provided on the outer side of each mounting hole, and the plurality of positioning grooves are arranged at intervals in the second direction.

[0030] The first limiting member and / or the second limiting member are provided with positioning protrusions, which are used to be inserted into each of the positioning slots in stages, so that the position of the negative pressure cup assembly relative to the corresponding mounting hole is adjustable in the second direction.

[0031] Compared with related technologies, this application has at least the following beneficial effects:

[0032] In this application, when the negative pressure cup needs to be installed on the mounting component, the second limiting member can be rotated to a second position; in this case, the second limiting member can pass through the mounting hole on the mounting component along the first direction. After the first limiting member passes through the mounting hole, the second limiting member can be rotated further to a first position; in this case, the first and second limiting members can respectively abut against the first and second opposite sides of the mounting component, and the elastic snap-fit ​​structure can also snap into the mounting component in the first direction. Thus, through the abutment of the first and second limiting members against the opposite sides of the mounting component, and the snap-fit ​​structure with the mounting component, the negative pressure cup can be more stably installed on the mounting component.

[0033] When it is necessary to disassemble the negative pressure cup, the second limiting member can be rotated to position it in the second working position. In this case, the second limiting member can pass through the mounting hole in the first direction, and the elastic locking structure can release its locking engagement with the mounting component. Thus, by having the second limiting member pass through the mounting hole and by having the elastic locking structure release its locking engagement with the mounting component, the disassembly operation of the negative pressure cup can be achieved.

[0034] As can be seen from the above description, this application can realize the installation and disassembly of the negative pressure cup by rotating the second limiting member to switch between the first and second working positions. Compared with related technologies, it does not require the disassembly and installation of a large number of bolts, thus simplifying the installation and disassembly of the negative pressure cup, reducing the difficulty of operation, and reducing the time consumption.

[0062] As described in the background section of this application, in the battery production process, the negative pressure cup in the formation process usually needs to be changed in number of channels to meet the production requirements of different batteries.

[0063] Changing the number of channels requires disassembling the negative pressure cup. However, in related technologies, the negative pressure cup is usually directly fixed to the mounting plate with bolts. This fixing method makes disassembly of the negative pressure cup require removing a large number of bolts, which is cumbersome, time-consuming, and difficult.

[0064] In view of the above-mentioned problems, this application provides a negative pressure cup assembly to solve the problems of cumbersome operation, time consumption and high operation difficulty when disassembling negative pressure cups in related technologies.

[0065] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings:

[0066] like Figure 1 and Figure 2 As shown, the negative pressure cup assembly 100 is used to be mounted on the mounting component 200, and the mounting component 200 is provided with a mounting hole 2001, which is a non-circular hole.

[0067] like Figure 3 As shown, the negative pressure cup assembly 100 includes a negative pressure cup 1, a first limiting member 2, a second limiting member 3, and an elastic snap-fit ​​structure 4. The negative pressure cup 1 includes a cup body 11 and a return pipe 12, which is connected to the cup body 11 and is used to pass through the mounting hole 2001.

[0068] The first limiting member 2 is disposed on the return pipe 12 and is used to abut against the first side 2002 of the mounting member 200 in the first direction. Figure 4 As shown), the first direction extends along the axial direction of the return pipe, and the elastic snap-fit ​​structure 4 is disposed on at least one of the first limiting member 2 and the return pipe 12.

[0069] The second limiting member 3 is located on the side of the first limiting member 2 away from the cup body 11, and is rotatably disposed on the return pipe 12 around the axis of the return pipe 12. During the rotation process, the second limiting member 3 passes through the first station and the second station in sequence.

[0070] like Figure 5 As shown, when the second limiting member 3 is located at the first station, the portion of the projection of the second limiting member 3 in the first direction is outside the mounting hole 2001, so that the second limiting member 3 and the second side 2003 of the mounting member 200 in the first direction abut against each other, and the elastic snap-fit ​​structure 4 snaps into the mounting member 200 in the first direction. The first side 2002 and the second side 2003 of the mounting member 200 are arranged opposite to each other in the first direction.

[0071] like Figure 6 As shown, when the second limiting member 3 is located at the second work station, the projection of the second limiting member 3 in the first direction is located in the mounting hole 2001, so that the second limiting member 3 can pass through the mounting hole 2001 in the first direction, and the elastic snap-fit ​​structure 4 can release the snap-fit ​​engagement with the mounting member 200.

[0072] With this configuration, when the negative pressure cup 1 needs to be installed on the mounting component 200, the second limiting member 3 can be rotated to position it in the second working position; in this case, the second limiting member 3 can pass through the mounting hole 2001 on the mounting component 200 along the first direction. After the first limiting member 2 passes through the mounting hole 2001, the second limiting member 3 can be rotated further to position it in the first working position. Figure 5(As shown); In this case, the first limiting member 2 and the second limiting member 3 can respectively abut against the first side 2002 and the second side 2003 disposed opposite to each other on the mounting member 200, and at the same time, the elastic snap-fit ​​structure 4 can also snap-fit ​​with the mounting member 200 in the first direction. Thus, through the abutment of the first limiting member 2 and the second limiting member 3 against the opposite sides of the mounting member 200, and the snap-fit ​​of the elastic snap-fit ​​structure 4 with the mounting member 200, the negative pressure cup 1 can be more stably installed on the mounting member 200.

[0073] When it is necessary to disassemble the negative pressure cup 1, the second limiting member 3 can be rotated to position the second limiting member in the second working position. Figure 6 (As shown); In this case, the second limiting member 3 can pass through the mounting hole 2001 in the first direction, and at the same time, the elastic snap-fit ​​structure 4 can release its snap-fit ​​engagement with the mounting member 200. Thus, by having the second limiting member 3 pass through the mounting hole 2001, and by having the elastic snap-fit ​​structure 4 release its snap-fit ​​engagement with the mounting member 200, the disassembly operation of the negative pressure cup 1 can be realized.

[0074] As can be seen from the above description, this application can realize the installation and disassembly of the negative pressure cup 1 by rotating the second limiting member 3 to switch between the first and second working positions. Compared with related technologies, it does not require the disassembly and installation of a large number of bolts, thus simplifying the installation and disassembly of the negative pressure cup 1, reducing the difficulty of operation, and reducing the time consumption.

[0075] In this embodiment, the first limiting member 2 can be fixedly and non-removably disposed on the return pipe 12, or it can be detachably disposed on the return pipe 12. The arrangement of the first limiting member 2 on the return pipe 12 is flexible. Specifically, it can be set according to actual needs. This embodiment does not make specific limitations on this.

[0076] Furthermore, in some alternative embodiments, such as Figure 3 As shown, the elastic snap-fit ​​structure 4 includes an elastic snap claw 41, which is disposed on the first limiting member 2.

[0077] like Figure 5 As shown, when the second limiting member 3 is located at the first station, the elastic claw 41 is used to abut against the second side 2003 of the mounting member 200 so that the elastic locking structure 4 and the mounting member 200 are locked together.

[0078] The elastic claw 41 is configured to elastically deform under the pressure of the wall of the mounting hole 2001, so as to release the engagement with the mounting member 200 when the second limiting member 3 passes through the mounting hole 2001 in the first direction.

[0079] With this configuration, when the second limiting member 3 is in the first working position, its contact with the second side 2003 of the mounting member 200 can achieve a stable connection between the elastic locking structure 4 and the mounting member 200, thus ensuring the stability and reliability of the negative pressure cup 1 after installation.

[0080] When the second limiting member 3 passes through the mounting hole 2001 in the first direction, the elastic claw 41 can undergo elastic deformation under the pressure of the wall of the mounting hole 2001, automatically releasing the engagement with the mounting member 200. Disassembly can be completed without additional operation, further simplifying the disassembly and assembly process of the negative pressure cup 1 and improving operational efficiency. At the same time, its elastic characteristics ensure the smoothness of the engagement and disassembly process.

[0081] In other embodiments, the elastic claw 41 can also be disposed on the return pipe 12, or on the return pipe 12 and the second limiting member 3. The placement of the elastic claw 41 is flexible and can be set according to actual needs; this application embodiment does not impose specific limitations on this.

[0082] In other embodiments, the elastic snap-fit ​​structure 4 may also include a snap-fit ​​bead, which is retractably disposed on the first limiting member 2, and the mounting hole 2001 has a slot on the hole wall for the snap-fit ​​bead to be inserted.

[0083] When the second limiting member 3 is in the first working position, the locking ball is inserted into the slot, realizing the locking engagement between the elastic locking structure 4 and the mounting member 200; when the second limiting member 3 is in the second working position, under the action of the force that drives the second limiting member 3 to pass through the mounting hole 2001 in the first direction, the locking ball can be removed from the slot, automatically releasing the locking engagement with the mounting member 200.

[0084] With this configuration, when the second limiting member 3 is in the first station, it can be inserted into the slot by the locking bead, so that the elastic locking structure 4 does not expose the mounting hole 2001, thereby enhancing the simplicity of the appearance and thus improving the aesthetics.

[0085] Furthermore, in some alternative embodiments, such as Figure 3 As shown, multiple elastic claws 41 are provided, and the multiple elastic claws 41 are spaced apart in the circumferential direction of the return pipe 12.

[0086] With this configuration, multiple elastic claws 41 can abut against the second side 2003 of the mounting component 200 from different directions, which can make the abutment force more evenly distributed in the circumferential direction of the return pipe 12, thereby further improving the stability and reliability of the negative pressure cup 1 on the mounting component 200, and at the same time avoiding the problem of loosening or failure of the clamping due to excessive force on a single elastic claw 41.

[0087] In other embodiments, a single elastic claw 41 may also be provided. This simplifies the specific structure of the elastic locking structure 4, thereby facilitating its manufacturing.

[0088] In some alternative embodiments, the second limiting member 3 is also movably disposed on the return pipe 12 along the first direction.

[0089] like Figure 3 As shown, an elastic member 5 is provided between the second limiting member 3 and the return pipe 12. The elastic member 5 is used to apply elastic force to the second limiting member 3 in the direction from the second side 2003 of the mounting member 200 to the first side 2002 of the mounting member 200.

[0090] With this configuration, firstly, the elastic force applied by the elastic member 5 allows the second limiting member 3 to abut more tightly against the second side 2003 of the mounting member 200 in the first working position. This, together with the first limiting member 2, can form a more stable clamping on the mounting member 200, thereby enhancing the firmness of the installation of the negative pressure cup 1 and effectively preventing the negative pressure cup 1 from loosening due to vibration or other factors during operation.

[0091] Secondly, the elastic element 5 can also play a buffering role, which can prevent the second limiting element 3 and the mounting element 200 from being worn due to hard contact, thereby extending the service life of the mounting element 200 and the second limiting element 3.

[0092] Finally, the second limiting member 3 is movably disposed on the return pipe 12 along the first direction. Before rotating the second limiting member 3, the second limiting member 3 can be pulled along the first direction to move the second limiting member 3 away from the mounting member 200. In this way, during the rotation of the second limiting member 3, wear caused by contact between the second limiting member 3 and the mounting member 200 can be avoided, thereby extending the service life of the mounting member 200 and the second limiting member 3.

[0093] In this embodiment, the elastic element 5 can be a helical spring, a wave spring, or an elastic rubber sleeve, etc. The type of elastic element 5 is flexible and can be selected according to actual needs. This embodiment does not impose specific limitations on this.

[0094] In other embodiments, the second limiting member 3 can be fixedly disposed on the return pipe 12 along the first direction. In this case, the elastic member 5 can be omitted, which not only simplifies the way the second limiting member 3 is disposed on the return pipe 12, but also simplifies the structural composition of the negative pressure cup assembly 100, thereby reducing the manufacturing cost of the negative pressure cup assembly 100.

[0095] Furthermore, in some alternative embodiments, such as Figure 7As shown, a nesting groove 21 is provided on the side of the first limiting member 2 near the second limiting member 3, and a nesting protrusion 31 is provided on the side of the second limiting member 3 near the first limiting member 2. The nesting protrusion 31 is movably disposed in the nesting groove 21 along the first direction and rotatably disposed in the nesting groove 21 around the axial direction of the return pipe 12.

[0096] This configuration, through the cooperation of the nested groove 21 and the nested protrusion 31, can limit the movement and rotation of the second limiting member 3, thereby ensuring stable and non-deviation-free movement when switching between the first and second workstations. At the same time, the cooperation of the nested groove 21 and the nested protrusion 31 can also enhance the tightness of the connection between the first limiting member 2 and the second limiting member 3, reduce the shaking of the two during relative movement or operation, improve the stability of the overall structure, and further ensure the reliability of the negative pressure cup 1 after installation and the smoothness of disassembly and assembly operations.

[0097] In other embodiments, a first contact surface may be provided on the side of the first limiting member 2 near the second limiting member 3, and a second contact surface may be provided on the side of the second limiting member 3 near the first limiting member 2, and the first contact surface and the second contact surface may be in contact with each other.

[0098] This design simplifies the structural configuration of the first limiting member 2 and the second limiting member 3, and facilitates the processing of the first limiting member 2 and the second limiting member 3.

[0099] Furthermore, in some alternative embodiments, such as Figure 7 As shown, the second limiting member 3 has an installation groove 32 on the side opposite to the first limiting member 2. The installation groove 32 extends along the axial direction of the return pipe 12 into the nested protrusion 31, and at least part of the elastic member 5 is disposed in the installation groove 32.

[0100] This configuration places at least a portion of the elastic element 5 within the mounting groove 32. The mounting groove 32, by limiting its movement, ensures the stability of the deformation direction of the elastic element 5, thereby guaranteeing the stability of the elastic force output direction. Simultaneously, it reduces the space occupied by the elastic element 5, resulting in a more compact overall structure.

[0101] Furthermore, in some alternative embodiments, such as Figure 8 As shown, one of the first limiting member 2 and the second limiting member 3 is provided with a pin 6, and the other is provided with a pin hole 7. The pin 6 is used to be inserted into the pin hole 7 when the second limiting member 3 is in the first working position.

[0102] This configuration allows the second limiting member 3 to be circumferentially limited by inserting the pin 6 into the pin hole 7 when it is in the first position. This effectively prevents the second limiting member 3 from rotating and deviating from the first position due to vibration, external force contact, or other unexpected situations during operation, further ensuring the stability of the negative pressure cup 1 after installation. At the same time, when it is necessary to switch to the second position, the limiting can be released simply by pulling out the pin 6. The operation is simple and does not affect the convenience of the disassembly and assembly process.

[0103] This application also provides a battery suction negative pressure device, such as Figure 1 and Figure 2 As shown, the battery suction negative pressure device includes a negative pressure cup assembly 100, a mounting component 200, and a negative pressure source (not shown in the figure). The mounting component 200 has multiple mounting holes 2001, which are non-circular holes. Multiple negative pressure cup assemblies 100 are provided, each corresponding to one of the mounting holes 2001. The structure of each negative pressure cup assembly 100 is the same as any of the negative pressure cup assemblies 100 in the above embodiments, and it can bring the same or similar beneficial effects. For details, please refer to the descriptions in the above embodiments; this embodiment will not repeat them here.

[0104] The negative pressure source is connected to the negative pressure cup 1 in the plurality of negative pressure cup assemblies 100 and is used to create negative pressure inside the negative pressure cup 1.

[0105] With this configuration, the installation and disassembly of the negative pressure cup 1 can be achieved by switching between the first and second working positions by rotating the second limiting member 3. Compared with related technologies, it does not require the disassembly and installation of many bolts, which simplifies the installation and disassembly of the negative pressure cup 1, reduces the difficulty of operation, and reduces the time consumption. Therefore, it facilitates the use of the battery suction negative pressure device.

[0106] Furthermore, in some alternative embodiments, such as Figure 9 and Figure 10 As shown, the mounting hole 2001 is a strip-shaped hole with a first length L1 and a first width B1. The second limiting member 3 is a strip-shaped member with a second length L2 and a second width B2. The second length L2 is less than the first length L1 and greater than the first width B1, and the second width B2 is less than the first width B1.

[0107] like Figure 9 As shown, when the second limiting member 3 is located at the first station, the second length L2 and the first width B1 extend in the same direction; as Figure 10 As shown, when the second limiting member 3 is located at the second station, the second length L2 and the first length L1 extend in the same direction, and the second width B2 and the first width B1 extend in the same direction. The first station rotates 90° relative to the second station.

[0108] With this configuration, when the second limiting member 3 rotates to the first station, since the second length L2 and the first width B1 extend in the same direction, and since the second length L2 is greater than the first width B1, the portion of the projection of the second limiting member 3 in the first direction is located outside the mounting hole 2001, thereby ensuring that the second limiting member 3 can abut against the second side 2003 in the first direction of the mounting member 200.

[0109] When the second limiting member 3 rotates to the second station, since the second length L2 and the first length L1 extend in the same direction, and the second width B2 and the first width B1 extend in the same direction, and since the second length L2 is less than the first length L1 and the second width B2 is less than the first width B1, the projection of the second limiting member 3 in the first direction can be located within the mounting hole 2001, thereby ensuring that the second limiting member 3 can pass through the mounting hole 2001 in the first direction.

[0110] Setting the mounting hole 2001 as a strip hole and the second limiting member 3 as a strip member simplifies the structure of the mounting hole 2001 and the second limiting member 3, thereby facilitating the processing of the mounting hole 2001 and the second limiting member 3.

[0111] In other embodiments, the mounting hole 2001 and the second limiting member 3 can be any other shape, but it must be ensured that when the second limiting member 3 is located at the first station, the portion of the projection of the second limiting member 3 in the first direction is outside the mounting hole 2001, and when the second limiting member 3 is located at the second station, the projection of the second limiting member 3 in the first direction is inside the mounting hole 2001. In this case, the angle of rotation of the first station relative to the second station can be any angle, specifically determined according to the specific shape of the mounting hole 2001 and the second limiting member 3.

[0112] In some alternative embodiments, such as Figure 1 As shown, multiple mounting holes 2001 are in the second direction (e.g.) Figure 1 Arranged at intervals in the X direction (as shown in the image), such as... Figure 5 As shown, on the side of the mounting member 200 near the first limiting member 2 and / or near the second limiting member 3, a plurality of positioning grooves 2004 are provided on the outer side of each mounting hole 2001, and the plurality of positioning grooves 2004 are arranged at intervals in the second direction.

[0113] like Figure 3 and Figure 5 As shown, the first limiting member 2 and / or the second limiting member 3 are provided with positioning protrusions 8. The positioning protrusions 8 are used to be inserted into each positioning groove 2004 in stages so that the negative pressure cup assembly 100 is positioned adjustable in the second direction relative to the corresponding mounting hole 2001.

[0114] With this configuration, depending on the different spacing between batteries on different trays, the spacing between two adjacent negative pressure cup assemblies 100 can be adjusted by inserting the positioning protrusion 8 into different positioning slots 2004. This, in turn, can adjust the spacing between the return pipes 12 in two adjacent negative pressure cup assemblies 100, thereby meeting the battery spacing requirements of different trays and improving compatibility.

[0115] In other embodiments, the negative pressure cup assembly 100 can be fixedly disposed on the mounting member 200 in the second direction. In this case, there is no need to provide the positioning groove 2004 and the positioning protrusion 8, which simplifies the structure of the mounting member 200 and the negative pressure cup assembly 100, and thus facilitates the processing of both.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
