Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a battery probe positioning mechanism and a charging and discharging device. Background Technology

[0002] During the production of lithium batteries, the batteries need to be continuously charged and discharged to test and adjust their performance. This process is also known as the charge and discharge capacity testing of lithium batteries.

[0003] To ensure stable and reliable charging and discharging of lithium batteries, the vertical projection positions of the probe and the battery terminals must coincide. If the probe deviates from the battery terminals, it will fail to effectively contact the terminals, affecting the charging and discharging process.

[0004] However, in actual production, there are errors in the thickness of lithium batteries and the thickness of spacers between batteries. Furthermore, during charging and discharging, the thickness of lithium batteries increases due to internal chemical reactions. These errors accumulate in the lithium battery queue, causing the deviation between the lithium batteries at the back of the queue and the corresponding probes to be sufficient to affect the normal charging and discharging of lithium batteries. Utility Model Content

[0005] In view of this, the present invention provides a battery probe positioning mechanism and a charging and discharging device to solve the problem of excessive deviation between the lithium battery and the probes in the queue.

[0006] In a first aspect, the present invention provides a battery probe positioning mechanism, including a fixed base and at least two positioning units arranged along a first direction;

[0007] The positioning unit includes:

[0008] There are two sliding seats, and both of them are slidably connected to the fixed seat along the first direction;

[0009] A probe assembly is slidably connected to two sliding seats along a second direction, the second direction intersecting the first direction, and the probe assembly is used to dock with the battery assembly;

[0010] There are two driving components, each mounted on a corresponding sliding seat and connected to the probe assembly. The driving components are used to jointly drive the probe assembly to slide.

[0011] A guide component is provided on the probe component, and the guide component is provided with a positioning groove for docking with a positioning protrusion on the battery component.

[0012] In one alternative implementation, the guiding component includes:

[0013] A guide block, which is slidably connected to the probe assembly along the second direction, and the guide block is provided with the positioning groove;

[0014] An elastic element is disposed between the guide block and the probe assembly, and is used to drive the guide block to slide toward the battery assembly.

[0015] In one optional embodiment, the guiding assembly further includes guide wheels, the positioning groove is configured as a V-shaped groove, and rotatable guide wheels are provided on both sides of the positioning groove, with the outer circumferential surface of the guide wheels protruding from the sidewall of the positioning groove.

[0016] In one alternative implementation, the two sliding seats are arranged along a third direction, and the third direction, the first direction, and the second direction intersect each other;

[0017] In the third direction, the probe assembly is disposed between the two sliding seats.

[0018] In one alternative embodiment, the drive assembly includes a fixing part and a drive part slidably connected to the fixing part;

[0019] The fixing part is connected to the side of the sliding seat near the battery assembly, and the driving part is arranged in a direction away from the battery assembly and connected to the probe assembly.

[0020] In one optional embodiment, the fixed base includes a base plate, a support plate, and a lifting plate;

[0021] The number of support plates is two, both of which extend along a third direction and are connected to the base plate. The lifting plate extends along the third direction and is tunably connected to the two support plates along the third direction.

[0022] The sliding seats are all slidably connected to the lifting plate.

[0023] In one optional embodiment, the lifting plate is provided with a through opening, and along the third direction, two sliding seats are distributed on both sides of the through opening, and the sliding seats are all located on the side of the lifting plate closer to the battery assembly.

[0024] The probe assembly is inserted through the through-hole, and the end of the probe assembly facing away from the battery assembly is connected to the drive assembly.

[0025] In one alternative embodiment, the probe assembly includes a mounting base and a probe, the mounting base being connected to two of the sliding seats, and the probe being disposed on the side of the mounting base near the battery assembly.

[0026] In one optional embodiment, the battery probe positioning mechanism further includes a reset drive device and a positioning structure;

[0027] The reset drive device and the positioning structure are both mounted on the fixed base. The reset drive device is located at one end of the queue formed by the positioning unit, and the positioning structure is located at the other end of the queue. The reset drive device is used to drive the queue to slide toward the positioning structure.

[0028] Secondly, this utility model also provides a charging and discharging device, including the battery probe positioning mechanism as described above.

[0029] The battery probe positioning mechanism provided by this utility model has probe components that are slidably connected to fixed seats through corresponding sliding seats, so that each probe component can adjust its position in the direction of battery arrangement, so that each probe component can adapt to the corresponding battery position, reducing the problem that the probe components cannot accurately align with the battery due to processing errors, assembly errors, and battery expansion.

[0030] In addition, since each probe component is driven by a corresponding driving component, the actions of the probe components will not affect each other, allowing the probe components to act sequentially. This ensures that after the previous probe component extends and accurately docks, the next probe component extends and docks, guaranteeing that each probe component has an accurate position.

[0031] In addition, the probe assembly is slidably connected to two sliding seats, which can improve the stability of the probe assembly sliding. The probe assembly is driven by the driving components on the two sliding seats, which can make the probe assembly subjected to balanced force and run smoothly, and can also provide sufficient insertion and extraction force between the probe assembly and the battery assembly.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] The following is combined with Figures 1 to 4 This describes the battery probe positioning mechanism provided in the embodiments of the present invention.

[0042] Specifically, the battery probe positioning mechanism includes a fixing base 1 and positioning units 2. There are at least two positioning units 2, arranged sequentially along the first direction X. It is understood that the batteries in the battery assembly 5 are also distributed along the first direction X.

[0043] Each positioning unit 2 includes a sliding base 201, a probe assembly 202, a drive assembly 203, and a guide assembly 204.

[0044] The number of sliding seats 201 is two, and the two sliding seats 201 are slidably connected to the fixed seat 1 along the first direction X. Optionally, the fixed seat 1 is provided with guide rails corresponding to the sliding seats 201, and the sliding seats 201 are slidably connected to the corresponding guide rails.

[0045] The probe assembly 202 is slidably connected to two sliding seats 201 along the second direction Y. Optionally, the two sliding seats 201 are distributed on opposite sides of the probe assembly 202 and are both slidably connected to the probe assembly 202. The second direction Y intersects the first direction X, for example, they are perpendicular. The probe assembly 202 is used to dock with the battery assembly 5. Specifically, the terminals of the battery in the battery assembly 5 are docked with the probe assembly 202.

[0046] There are two drive components 203, each mounted on a corresponding slide seat 201. Optionally, the two drive components 203 are mounted one-to-one on their respective slide seats 201. Both drive components 203 are connected to the probe component 202 and are used to drive the probe component 202 to slide, allowing the probe component 202 to dock with or detach from the battery component 5. The two drive components 203 work together to drive the probe component 202 to slide.

[0047] A guide component 204 is disposed on the probe component 202, and the guide component 204 is provided with a positioning groove 2041. The positioning groove 2041 is used to mate with the positioning protrusion 501 on the battery component 5. For example, the positioning groove 2041 faces the battery component 5.

[0048] In this embodiment, during use, the probe assembly 202 is driven by two driving components 203 to move closer to the battery assembly 5. The positioning groove 2041 of the guide component 204 mates with the positioning protrusion 501 on the battery assembly 5. During the alignment of the positioning protrusion 501 and the positioning groove 2041, the guide component 204 drives the probe assembly 202 and the sliding seat 201 to slide on the fixed seat 1 so that the probe assembly 202 is aligned with the battery terminal of the battery assembly 5.

[0049] With this configuration, each probe assembly 202 is slidably connected to the fixed base 1 via a corresponding sliding seat 201, allowing each probe assembly 202 to adjust its position in the direction of the battery arrangement. This ensures that each probe assembly 202 can adapt to the corresponding battery position, reducing the problem of the probe assembly 202 failing to accurately align with the battery due to processing errors, assembly errors, or battery expansion.

[0050] In addition, since each probe assembly 202 is driven by a corresponding drive assembly 203, the actions of the probe assemblies 202 will not affect each other, so that the probe assemblies 202 can act sequentially, so that after the previous probe assembly 202 extends and accurately docks, the next probe assembly 202 extends and docks, ensuring that each probe assembly 202 has an accurate position.

[0051] In addition, the probe assembly 202 is slidably connected to the two sliding seats 201, which can improve the sliding stability of the probe assembly 202. The probe assembly 202 is driven by the driving components 203 on the two sliding seats 201, which can make the probe assembly 202 subject to balanced force and run smoothly, and can also make the probe assembly 202 and the battery assembly 5 have sufficient insertion and extraction force.

[0052] In some embodiments provided by this utility model, the guide component 204 includes a guide block 2042 and an elastic element.

[0053] The guide block 2042 is slidably connected to the probe assembly 202 along the second direction Y. For example, the probe assembly 202 is provided with a guide rail extending along the second direction Y, and the guide hole is slidably connected to the guide rail. The guide block 2042 is provided with a positioning groove 2041.

[0054] An elastic element is disposed between the guide block 2042 and the probe assembly 202, and the elastic element is used to drive the guide block 2042 to slide towards the battery assembly 5. For example, the elastic element is configured as a spring, with its two ends abutting against the guide hole and the probe assembly 202, respectively.

[0055] In this embodiment, by slidably connecting the guide block 2042 to the probe assembly 202 and driving the guide block 2042 to slide towards the battery assembly 5 with the elastic element, after the positioning protrusion 501 is inserted into the positioning groove 2041, the guide block 2042 can compress the elastic element and slide relative to the probe assembly 202, so as to avoid the guide block 2042 from contacting the positioning protrusion 501 and hindering the probe assembly 202 from sliding towards the battery assembly 5.

[0056] In addition, after the probe assembly 202 disengages from the battery assembly 5, the guide block 2042 can be reset under the action of the elastic element so that it can dock with the positioning protrusion 501 of the battery assembly 5 next time.

[0057] In some embodiments of this utility model, the guide assembly 204 further includes guide wheels 2043. The positioning groove 2041 is configured as a V-shaped groove, and rotatable guide wheels 2043 are provided on both sides of the positioning groove 2041. The outer circumferential surface of the guide wheel 2043 protrudes from the sidewall of the positioning groove 2041. Correspondingly, the positioning protrusion 501 is configured as a V-shaped protrusion or a trapezoidal protrusion.

[0058] In this embodiment, by setting the positioning groove 2041 as a V-shaped groove, the V-shaped groove can provide an automatic centering function when used in conjunction with a V-shaped protrusion or a trapezoidal protrusion, thereby ensuring the accuracy of docking.

[0059] In addition, since the guide wheel 2043 is rotatable and its outer circumferential surface protrudes from the side wall of the positioning groove 2041, the sliding friction between the positioning groove 2041 and the positioning protrusion 501 can be significantly reduced, and instead become rolling friction, thereby reducing wear and improving durability.

[0060] refer to Figure 3 and Figure 4 As shown, in some embodiments provided by this utility model, two sliding seats 201 are arranged along a third direction Z, and the third direction Z, the first direction X, and the second direction Y intersect each other. For example, the third direction Z, the first direction X, and the second direction Y are perpendicular to each other.

[0061] In the third direction Z, the probe assembly 202 is disposed between the two sliding seats 201. Correspondingly, two drive assemblies 203 are respectively disposed on the two sliding seats 201, so the two drive assemblies 203 are distributed on opposite sides of the probe assembly 202.

[0062] In this embodiment, two sliding seats 201 and two driving components 203 are arranged on both sides of the probe assembly 202. This can make full use of the size of the battery probe positioning mechanism in the third direction Z. Furthermore, the travel path of the driving component 203 is arranged in parallel with the travel path of the probe assembly 202, thereby reducing the size of the battery probe positioning mechanism in the second direction Y, improving the compactness of the battery probe positioning mechanism in the second direction Y, and thus reducing the floor space occupied by the battery probe positioning mechanism.

[0063] refer to Figure 4 As shown, in some embodiments provided by this utility model, the drive assembly 203 includes a fixing part 2031 and a drive part 2032 that is slidably connected to the fixing part 2031.

[0064] The fixing part 2031 is connected to the side of the sliding seat 201 near the battery assembly 5, and the driving part 2032 is arranged in a direction away from the battery assembly 5 and is connected to the probe assembly 202.

[0065] In this embodiment, the travel path of the drive component 203 is arranged in parallel with the travel path of the probe component 202, thereby reducing the size of the battery probe positioning mechanism in the second direction Y, improving the compactness of the battery probe positioning mechanism in the second direction Y, and thus reducing the floor space occupied by the battery probe positioning mechanism.

[0066] Optionally, the drive assembly 203 includes a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. Accordingly, the drive part 2032 is configured as a drive rod, and the fixing part 2031 is configured as a cylinder body.

[0067] In some embodiments provided by this utility model, the fixed base 1 includes a base plate 101, a support plate 102, and a lifting plate 103.

[0068] There are two support plates 102, both of which extend along the third direction Z and are connected to the base plate 101, for example, by screwing or welding the support plates 102 to the base plate 101.

[0069] The lifting plate 103 extends along the third direction Z and is arbitrarily connected to the two support plates 102 along the third direction Z. Specifically, both ends of the lifting plate 103 are arbitrarily connected to the two support plates 102 along the third direction Z.

[0070] The sliding seats 201 are all slidably connected to the lifting plate 103.

[0071] In this embodiment, by connecting the two support plates 102 to the base plate 101, the base plate 101 facilitates the formation of a single unit for the fixed seat 1. By connecting the lifting plate 103 to the two support plates 102, the lifting plate 103 becomes more stable.

[0072] By making the lifting plate 103 adjustable along the third direction Z, the position height of the probe assembly 202 can be adjusted by adjusting the position of the lifting plate 103 in the third direction Z, so that the position height of the probe assembly 202 can be adapted to the position height of the battery terminal of the battery assembly 5.

[0073] refer to Figure 3 As shown, optionally, the battery probe positioning mechanism also includes a locking bolt 106. The support plate 102 is provided with a slotted hole 105 extending along a third direction Z, the slotted hole 105 penetrating the support plate 102 along a first direction X, and the locking bolt 106 passing through the slotted hole 105 and threadedly connected to the lifting plate 103. Thus, the position of the lifting plate 103 can be adjusted after the locking bolt 106 is loosened.

[0074] Optionally, the support plate 102 is provided with a guide groove that extends along the third direction Z, with the opening of the guide groove facing the lifting plate 103. The lifting plate 103 slides in conjunction with the guide groove. This arrangement allows the lifting plate 103 to be limited in the second direction Y by the guide groove.

[0075] Optionally, the battery probe positioning mechanism also includes a positioning bolt 107. The positioning bolt 107 extends in the third direction Z and is threadedly connected to the support plate 102. For example, a threaded seat can be installed on the support plate 102, and the positioning bolt 107 is threadedly connected to the threaded seat.

[0076] The positioning bolt 107 is used to abut against the end of the lifting plate 103 near the base plate 101 and to limit the lifting plate 103 in the third direction Z.

[0077] In this embodiment, by abutting the positioning bolt 107 against the lifting plate 103, the problem of the single lifting plate 103 shifting downward due to vibration or gravity can be prevented, ensuring the accurate position of the lifting plate 103. By threading the positioning bolt 107 to the support plate 102, the position of the positioning bolt 107 can be adapted to the position of the lifting plate 103 by tightening the positioning bolt 107.

[0078] Of course, in some embodiments not shown, the lifting plate 103 may also be raised or lowered by a cylinder, hydraulic cylinder or electric cylinder.

[0079] In some embodiments of this utility model, the lifting plate 103 is provided with a through opening 104. Along the third direction Z, two sliding seats 201 are distributed on both sides of the through opening 104, and the sliding seats 201 are both located on the side of the lifting plate 103 closest to the battery assembly 5. Correspondingly, the fixing part 2031 of the drive assembly 203 is connected to the sliding seat 201 on the side closest to the battery assembly 5.

[0080] The probe assembly 202 passes through the through-hole 104, and the end of the probe assembly 202 facing away from the battery assembly 5 is connected to the drive assembly 203. Specifically, the end of the probe assembly 202 facing away from the battery assembly 5 is connected to the drive part 2032 of the drive assembly 203.

[0081] In this embodiment, two sliding seats 201 and two driving components 203 are arranged on both sides of the through opening 104, and the probe component 202 passes through the through opening 104. This can make full use of the size of the battery probe positioning mechanism in the third direction Z. Furthermore, the travel path of the driving component 203 is arranged in parallel with the travel path of the probe component 202, thereby reducing the size of the battery probe positioning mechanism in the second direction Y, improving the compactness of the battery probe positioning mechanism in the second direction Y, and thus reducing the floor space occupied by the battery probe positioning mechanism.

[0082] In some embodiments provided by this utility model, the probe assembly 202 includes a mounting base 2021 and a probe 2022. The mounting base 2021 is connected to two sliding seats 201, and the probe 2022 is disposed on the side of the mounting base 2021 near the battery assembly 5.

[0083] In some embodiments provided by this utility model, the battery probe positioning mechanism further includes a reset drive device 3 and a positioning structure 4.

[0084] Both the reset drive device 3 and the positioning structure 4 are mounted on the fixed base 1. At least two positioning units 2 are arranged in a queue along the first direction X. The reset drive device 3 is located at one end of the queue formed by the positioning units 2, and the positioning structure 4 is located at the other end of the queue. The reset drive device 3 is used to drive the queue to slide towards the positioning structure 4.

[0085] During the charging and discharging process of the battery assembly 5, the positioning groove 2041 and the positioning protrusion 501 cooperate, causing the gap between the positioning units 2 to change. In this embodiment, after the charging and discharging of the battery assembly 5 is completed, the positioning unit 2 can be driven by the reset drive device 3. Then the positioning unit 2 will abut against and finally abut against the positioning structure 4 in sequence, so that all the positioning units 2 can be reset to the initial position for the next docking with the battery assembly 5.

[0086] Optionally, the reset drive device 3 is configured as a pneumatic cylinder, hydraulic cylinder, or electric cylinder.

[0087] This utility model embodiment also provides a charging and discharging device.

[0088] Specifically, the charging and discharging device includes the battery probe positioning mechanism as described above.

[0089] It should be noted that the charging and discharging device includes a battery probe positioning mechanism, and thus also includes all the advantages of the battery probe positioning mechanism mentioned above, so it will not be elaborated further.

[0090] Furthermore, there are two battery probe positioning mechanisms, which are arranged opposite each other and spaced apart, with the battery assembly 5 positioned between them. This arrangement allows the two battery probe positioning mechanisms to abut against the terminals at both ends of the battery, making the charging and discharging device suitable for batteries with positive and negative terminals distributed at both ends.

[0091] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
