Formation equipment Technical Field

[0001] The present application relates to the technical field of battery production, and in particular to a formation device. Background Art

[0002] During the battery production process, formation and discharging are required. In some cases, the power supply used to charge and discharge the battery is usually placed separately from the formation device, resulting in long power supply lines.

[0003] Application Contents

[0004] The purpose of the embodiments of the present application is to provide a formation device that can improve the technical problem of a long power supply line caused by the power supply and the formation device being placed separately.

[0005] The technical solution adopted in the embodiment of this application is:

[0006] A formation device is provided, comprising a needle bed assembly, the needle bed assembly comprising:

[0007] Support components;

[0008] a needle bed disposed on the support member so as to be movable relative to the support member along a first direction; and

[0009] The power supply component is arranged on the needle bed.

[0010] The above technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0011] In the formation device provided in the embodiments of the present application, since the power supply assembly is disposed on the needle bed, i.e., the power supply assembly and the needle bed are integrated, the length of the power supply line between the power supply assembly and the needle bed can be effectively shortened, thereby improving the structural compactness and space utilization. Furthermore, the needle bed can be movably disposed on the support member in a first direction relative to the support member, facilitating the withdrawal or retraction of the needle bed in the first direction. The power supply assembly can also move simultaneously with the needle bed, facilitating the inspection and maintenance of the needle bed and the power supply assembly.

[0012] In some embodiments, the support member comprises:

[0013] a first guide member extending along the first direction; and

[0014] a second guide member, spaced apart from and parallel to the first guide member;

[0015] The needle bed is movably arranged on the first guide member and the second guide member along the first direction.

[0016] By adopting the above technical solution, the first guide member and the second guide member arranged in parallel can not only improve the stability of the needle bed movement but also have a simple structure.

[0017] In some embodiments, the needle bed is located in a space formed between the first guide and the second guide.

[0018] By adopting the above technical solution, the height of the whole formed by the needle bed and the first guide member and the second guide member can be reduced, which is conducive to reducing the overall height of the needle bed assembly and thus reducing the height of the formation device.

[0019] In some embodiments, a first guide groove is provided on one of the first guide member and the needle bed, and a first movable member is provided on the other; the first movable member is disposed in the first guide groove so as to be movable relative to the first guide groove along the first direction;

[0020] A second guide groove is provided on one of the second guide member and the needle bed, and a second movable member is provided on the other; the second movable member is arranged in the second guide groove so as to be movable relative to the second guide groove along the first direction.

[0021] By adopting the above technical solution, the cooperation between the groove and the moving part is conducive to improving the connection reliability of the needle bed and the supporting component in the movable cooperation, and reducing the possibility of the needle bed being separated from the supporting component.

[0022] In some embodiments, one of the first guide groove and the first moving member provided on the first guide member is located on a side of the first guide member facing the second guide member;

[0023] One of the second guide groove and the second moving member provided on the second guide member is located on a side of the second guide member facing the first guide member.

[0024] By adopting the above technical solution, it is helpful to reduce the space occupied along the height direction of the needle bed assembly, thereby helping to reduce the overall height of the needle bed assembly.

[0025] In some embodiments, the needle bed is movable along the first direction away from the support member to an extracted position, and is movable along the first direction toward the support member to a pushed-back position;

[0026] The supporting component is provided with a positioning piece for positioning the needle bed when the needle bed moves to the push-back position.

[0027] By adopting the above technical solution, when the needle bed moves from the withdrawn position to the pushed-back position, the needle bed can be positioned by the positioning member, which helps the needle bed to accurately move to the preset positioning position.

[0028] In some embodiments, the positioning member is provided with a contact portion and a stop portion; the needle bed is provided with a contact matching portion and a stop matching portion, the contact matching portion is used to frictionally contact with the contact portion when the needle bed moves to the push-back position, and the stop matching portion is used to abut against the stop portion when the needle bed moves to the push-back position.

[0029] By adopting the above technical solution, when the needle bed moves from the withdrawn position to the pushed-back position, the contact matching part and the contact part are in frictional contact, which can buffer the needle bed and limit the random movement of the needle bed; and the stop matching part can abut against the stop part to limit the needle bed from continuing to move in the first direction.

[0030] In some embodiments, when the needle bed is in the withdrawn position, the contact portion is located on a side of the stop portion facing the needle bed.

[0031] By adopting the above technical solution, the contact matching part does not need to extend outward to contact and match with the contact part located on the side of the stop part facing away from the needle bed, and the size does not need to be set too large, which is conducive to simplifying the structure of the contact matching part and the stop matching part.

[0032] In some embodiments, a first guide portion is further provided on the positioning member; when the needle bed is in the withdrawn position, the first guide portion is located on the side of the contact portion facing the needle bed, and is used to guide the contact fitting portion to move into frictional contact with the contact portion.

[0033] By adopting the above technical solution, the movement of the needle bed can be buffered, thereby reducing the possibility of the contact and matching portion directly colliding with the positioning piece.

[0034] In some embodiments, at least one load-bearing member is provided on the support component, and the load-bearing member has a limiting portion, which is located on one side of the needle bed in the height direction of the needle bed and is used to limit the movement of the needle bed along the height direction.

[0035] By adopting the above technical solution, when the needle bed is subjected to force and moves relative to the supporting component, it can be offset against the limiting portion to limit the needle bed from continuing to move.

[0036] In some embodiments, at least one pad is provided on the needle bed. When the needle bed moves along the first direction toward the support component to the push-back position, the pad corresponds one-to-one with the load-bearing component, and the pad is located between the needle bed and the limiting portion.

[0037] By adopting the above technical solution, when the needle bed is in the pushed-back position, the cushion is located between the limiting part and the needle bed. If the needle bed is subjected to force and moves along its own height direction, the cushion abuts against the limiting part; when the needle bed moves along the first direction relative to the supporting component, the cushion can be separated from the limiting part, which can reduce the resistance generated by friction between the needle bed and the limiting part, and is conducive to improving the smoothness of the movement of the needle bed.

[0038] In some embodiments, a first through hole is provided on the limiting portion of at least one of the load-bearing members, and the needle bed assembly further includes a first locking member, which is movably disposed in the first through hole and is used to connect with the needle bed.

[0039] By adopting the above technical solution, the first locking member can easily lock the needle bed to limit the movement of the needle bed relative to the supporting component.

[0044] An adjusting member is adjustably arranged on the mounting member, and one end of the adjusting member is used to abut against the load-bearing member or the supporting member.

[0045] By adopting the above technical solution, by applying force to the adjusting member, the adjusting member abuts against the load-bearing member and can drive the needle bed to move relative to the load-bearing member or the supporting component. The structure of the adjusting mechanism is simple and is conducive to fine-tuning.

[0046] In some embodiments, the power supply component is a DC / DC power supply component.

[0069] By adopting the above technical solution, the probe mechanism can move on the guide portion through the sliding portion, which is beneficial to improving the stability and reliability of the movement of the probe mechanism.

[0070] In some embodiments, the probe mechanism comprises:

[0071] a probe mounting member, disposed on the support body; and

[0072] A plurality of probes are sequentially arranged on the probe mounting member;

[0073] The probe mounting member is provided with a plurality of mounting parts, and the probes correspond to the mounting parts one by one; the mounting part includes a plurality of sub-mounting parts, and the probes corresponding to the mounting parts are selectively arranged on the sub-mounting parts.

[0074] By adopting the above technical solution, the probe mounting assembly can simultaneously support and mount multiple probes, allowing each probe to electrically contact the battery terminals. The probes can be selectively mounted on any sub-mounting portion of the corresponding mounting portion, making the position of the probes on the probe mounting assembly adjustable, making it suitable for batteries of different types and sizes.

[0075] In some embodiments, the probe mechanism further includes a probe side guard plate, and the probe side guard plate is disposed on the probe mounting member.

[0076] By adopting the above technical solution, the probe side guard plate can provide protection for the probe and reduce the possibility of the probe being interfered with by the outside.

[0077] In some embodiments, at least one through hole is formed on the probe side guard plate.

[0078] By adopting the above technical solution, air flow is facilitated to facilitate heat dissipation.

[0079] In some embodiments, the needle bed further comprises a locking mechanism, wherein the locking mechanism is used to limit the movement of the probe mechanism relative to the support body.

[0080] By adopting the above technical solution, after the probe mechanism is adjusted to move to a desired position relative to the support body, the movement of the probe mechanism can be restricted by the locking mechanism, which helps to improve the position stability of the probe mechanism.

[0097] In some embodiments, the needle bed further comprises a ruler, and the ruler is disposed on the support body.

[0098] By adopting the above technical solution, it is helpful to quantify the moving distance of the probe mechanism, thereby improving the accuracy of the movement of the probe mechanism.

[0099] In some embodiments, the needle bed further comprises a pointer, which is disposed on the probe mechanism, and a needle end of the pointer is located on one side of the ruler.

[0100] By adopting the above technical solution, it is convenient to intuitively judge the movement size of the probe mechanism.

[0101] In some embodiments, the formation device further includes a press, and the supporting component is disposed on the press.

[0102] By adopting the above technical solution, when the battery needs to be formed and / or divided into different capacities, the battery can be carried by the press, so that the battery can be in electrical contact with the needle bed.

[0103] In some embodiments, the press comprises:

[0104] Support components;

[0105] a driving mechanism, disposed on the supporting assembly; and

[0106] A supporting member connected to the power output end of the driving mechanism;

[0107] Wherein, the supporting component is arranged on the supporting assembly.

[0108] By adopting the above technical solution, the supporting member can support the battery, and the driving mechanism can drive the supporting member to move closer to or away from the needle bed, so as to facilitate electrical contact between the battery and the needle bed.

[0170] In order to make the purpose, technical solutions and advantages of this application more clear, this application is further described in detail below with reference to the accompanying drawings and embodiments.

[0171] Batteries are widely used in various fields and can be used to provide electrical energy for electrical devices. For example, they can provide electrical energy for electrical devices in the field of electric vehicles such as electric bicycles, electric motorcycles, and electric cars, and can also provide electrical energy for electrical devices in various fields such as military equipment and aerospace. Of course, batteries can also be used in energy storage systems such as hydropower, thermal power, wind power, and solar power stations to store electrical energy.

[0172] During the battery production process, formation and capacity grading are required. Formation refers to the initial charging of the battery, which activates the active materials within the battery. After formation, the battery needs to be capacity graded, and qualified batteries can be screened through capacity testing. Capacity grading typically involves charging and discharging the battery, measuring the discharge capacity when fully charged to determine the battery's capacity. If the tested capacity is greater than or equal to the designed capacity, the battery is considered qualified; if the tested capacity is less than the designed capacity, it is considered unqualified.

[0173] A formation device is a device used to form batteries, or a device that can both form and separate batteries. In some cases, the power supply used to charge and discharge the batteries is often placed separately from the formation device, with the two devices separated by a certain distance. These two devices are then connected by a power line, resulting in a long power line.

[0174] Based on this, and to address the technical issue of long power lines resulting from the separate placement of the power supply and formation device, embodiments of the present application provide a formation device that integrates the power supply assembly with the needle bed by placing it on the needle bed, thereby shortening the length of the power line between the power supply assembly and the needle bed. Furthermore, the needle bed is movably disposed on a support member along a first direction, facilitating the simultaneous withdrawal or retraction of the needle bed and the power supply assembly along the first direction, thereby facilitating the inspection, maintenance, or commissioning of the needle bed and the power supply assembly.

[0175] The formation device disclosed in the embodiments of the present application can be used to form and / or separate the capacity of batteries.

[0176] Next, the formation device provided in the embodiments of the present application will be introduced and described.

[0177] Please refer to Figures 1 to 3. Figure 1 shows a structural schematic diagram of a formation device 1000 provided in some embodiments of the present application. Figure 2 shows a decomposed structural schematic diagram of the internal structure of the formation device 1000 shown in Figure 1. Figure 3 shows a structural schematic diagram of a needle bed assembly 100 provided in some embodiments of the present application.

[0178] The formation device 1000 includes a needle bed assembly 100 , which includes a support component 10 , a needle bed 20 and a power supply assembly 30 ; the needle bed 20 is movably arranged on the support component 10 along a first direction A relative to the support component 10 ; the power supply assembly 30 is arranged on the needle bed 20 .

[0179] It is understood that the needle bed assembly 100 refers to an assembly including a probe for electrically contacting a battery, thereby facilitating formation and / or capacity separation of the battery by the formation device 1000. The number of needle bed assemblies 100 can be one or more, and Figures 1 and 2 exemplarily illustrate two needle bed assemblies 100 arranged side by side.

[0180] The support component 10 is a supporting structure that can provide support and installation for the needle bed 20 and the power supply assembly 30. The support component 10 can be a variety of structures, such as a bracket structure, a frame structure, a guide rail structure, etc., but is not limited thereto.

[0181] The needle bed 20 is the actuator of the needle bed assembly 100 for electrically contacting the battery, and includes at least one probe for electrically contacting the battery. The needle bed 20 can be of various structural forms, such as a frame structure, a plate structure, etc., but is not limited thereto.

[0182] The needle bed 20 can be mounted on the support member 10 using a variety of movable connection methods, such as, but not limited to, a sliding fit or a rolling fit. As long as the needle bed 20 is movable relative to the support member 10 in a first direction A, that is, the needle bed 20 is movable in a generally linear direction, the first direction A can be any linear direction, such as, but not limited to, the length or width of the support member 10.

[0183] The power supply assembly 30 is a component that delivers or converts voltage to the needle bed 20, facilitating electrical contact between the needle bed 20 and the battery for battery formation and / or capacity division. For example, the power supply assembly 30 may include at least one of a DC / DC power supply assembly and an AC / DC power supply assembly. Because the power supply assembly 30 is mounted on the needle bed 20, the two are connected and integrated, allowing simultaneous movement relative to the support member 10.

[0184] The power supply assembly 30 can be set on the needle bed 20 through a variety of installation and connection methods, for example, it can be connected, clamped, plugged, welded, etc. through fasteners (such as screws, bolts, pins, rivets, clamps, ropes, etc., but not limited to these), but not limited to these.

[0185] As can be seen from the foregoing, the formation device 1000 provided in the embodiment of the present application, because the power supply assembly 30 is disposed on the needle bed 20, i.e., the power supply assembly 30 and the needle bed 20 are integrated, can effectively shorten the length of the power line connecting the power supply assembly 30 and the needle bed 20 compared to a case where they are placed separately, thereby improving the compactness of the structure and space utilization. Furthermore, the needle bed 20 can be movably disposed on the support member 10 along the first direction A relative to the support member 10, facilitating the withdrawal or retraction of the needle bed 20 along the first direction A. The power supply assembly 30 can also move simultaneously with the needle bed 20, facilitating the inspection, maintenance, or debugging of the needle bed 20 and the power supply assembly 30.

[0186] In some embodiments, referring to FIG3 , the support member 10 includes a first guide member 11 and a second guide member 12 . The first guide member 11 extends along a first direction A; the second guide member 12 is spaced apart from and parallel to the first guide member 11 , i.e., the second guide member 12 also extends along the first direction A. The needle bed 20 is movably disposed on the first guide member 11 and the second guide member 12 along the first direction A.

[0187] It can be understood that the first guide member 11 and the second guide member 12 are both structural members that guide the movement of the needle bed 20, and can be, for example, guide rails, guide bars, guide plates, etc., but are not limited thereto.

[0188] With such arrangement, the needle bed 20 can move along the first direction A on the first guide member 11 and the second guide member 12. The parallel arrangement of the first guide member 11 and the second guide member 12 not only improves the movement stability of the needle bed 20 but also simplifies the structure.

[0189] Optionally, in some embodiments, refer to Figure 3, the needle bed 20 is located in the space formed between the first guide member 11 and the second guide member 12, that is, at least part of the needle bed 20 is located in the space formed between the first guide member 11 and the second guide member 12.

[0190] With such an arrangement, compared with the case where the needle bed 20 is stacked above the first guide member 11 and the second guide member 12, the height of the whole formed by the needle bed 20 and the first guide member 11 and the second guide member 12 can be reduced, which is beneficial to reducing the overall height of the needle bed assembly 100, thereby reducing the height of the formation device 1000. When multiple formation devices 1000 are required to be stacked along the height direction H of the formation device 1000, it is beneficial to reduce the overall height formed by the stacking arrangement.

[0191] It can be understood that the height direction H of the formation device 1000 refers to the direction perpendicular to the plane where the first guide member 11 and the second guide member 12 are located. The height direction H of the formation device 1000 is also the height direction of the needle bed assembly 100 and the height direction of the needle bed 20.

[0192] Of course, the setting position of the needle bed 20 is not limited to this. In some other embodiments, the needle bed 20 may also be located above the space formed between the first guide member 11 and the second guide member 12, instead of being located in the space formed between the first guide member 11 and the second guide member 12.

[0193] Please refer to Figures 3 to 6. Figure 4 shows a schematic diagram of the decomposed structure of the needle bed assembly 100 shown in Figure 3 from another perspective. Figure 5 shows a schematic diagram of the three-dimensional structure of the needle bed assembly 100 shown in Figure 3 from yet another perspective. Figure 6 shows a schematic diagram of the decomposed structure of the needle bed assembly 100 provided in some embodiments of the present application.

[0194] Optionally, in some embodiments, one of the first guide member 11 and the needle bed 20 is provided with a first guide slot 111, and the other is provided with a first movable member 112. The first movable member 112 is movably disposed in the first guide slot 111 along a first direction A relative to the first guide slot 111.

[0195] One of the second guide member 12 and the needle bed 20 is provided with a second guide slot 121, and the other is provided with a second movable member 122. The second movable member 122 is disposed in the second guide slot 121 so as to be movable along a first direction A relative to the second guide slot 121.

[0196] It is understood that the first movable member 112 and the second movable member 122 are structural members that can move in the groove, and can be, for example, sliding members that slide in the groove (such as, but not limited to, sliders, slide rails, etc.), or rolling members that roll in the groove (such as, but not limited to, bearings, rollers, etc.). The first guide groove 111 and the second guide groove 121 can be arranged to extend substantially along the first direction A.

[0197] In this arrangement, the needle bed 20 can be moved relative to the first guide member 11 and the second guide member 12 by moving the first moving member 112 in the first guide groove 111 and the second moving member 122 in the second guide groove 121. The cooperation between the groove and the moving member is conducive to improving the connection reliability of the movement cooperation between the needle bed 20 and the support component 10, reducing the possibility of the needle bed 20 detaching from the support component 10, and helping to improve the stability of guiding the movement of the needle bed 20.

[0198] For example, referring to Figures 3 to 6, the first guide member 11 is provided with a first guide groove 111, and the needle bed 20 is provided with a first movable member 112. For example, the first movable member 112 can be provided on the side of the needle bed 20 facing the first guide member 11. The second guide member 12 is provided with a second guide groove 121, and the needle bed 20 is provided with a second movable member 122. For example, the second movable member 122 can be provided on the side of the needle bed 20 facing the second guide member 12.

[0199] Such an arrangement facilitates the arrangement of the first guide groove 111 and the second guide groove 121 , and can avoid the problem that the structural size of the needle bed 20 needs to be increased due to the arrangement of the guide grooves on the needle bed 20 .

[0200] Of course, in other embodiments, the first guide member 11 may be provided with a first moving member 112, and the needle bed 20 may be provided with a first guide groove 111. Alternatively, the second guide member 12 may be provided with a second moving member 122, and the needle bed 20 may be provided with a second guide groove 121.

[0201] 3 to 6 , the one of the first guide groove 111 and the first movable member 112 provided on the first guide member 11 is located on the side of the first guide member 11 facing the second guide member 12. The one of the second guide groove 121 and the second movable member 122 provided on the second guide member 12 is located on the side of the second guide member 12 facing the first guide member 11.

[0202] In this arrangement, one of the first guide groove 111 and the first movable member 112 provided on the first guide member 11 and one of the second guide groove 121 and the second movable member 122 provided on the second guide member 12 are located between the first guide member 11 and the second guide member 12. Compared with other positions such as above or below the first guide member 11 and the second guide member 12, this is not only beneficial to reducing the space occupied along the height direction H of the needle bed assembly 100, thereby helping to reduce the overall height of the needle bed assembly 100, but also beneficial to reducing interference from components or objects outside the first guide member 11 and the second guide member 12, thereby improving reliability.

[0203] Of course, in some other embodiments, one of the first guide groove 111 and the first movable member 112 provided on the first guide member 11 may also be located on the side of the first guide member 11 facing away from the second guide member 12, or may be located above or below the first guide member 11 in the height direction H of the needle bed assembly 100.

[0204] Similarly, one of the second guide groove 121 and the second movable member 122 provided on the second guide member 12 can also be located on the side of the second guide member 12 facing away from the first guide member 11, or can be located above or below the second guide member 12 in the height direction H of the needle bed assembly 100.

[0205] 4 , 6 and 8 , the first moving member 112 includes a first rolling member 1121 rollably disposed in the first guide groove 111 , and the second moving member 122 includes a second rolling member 1221 rollably disposed in the second guide groove 121 .

[0206] It can be understood that the first rolling element 1121 and the second rolling element 1221 are structural elements that can rotate to roll on an object, such as bearings, rollers, etc., but are not limited thereto.

[0207] With such a configuration, when the needle bed 20 moves along the first direction A relative to the supporting component 10, the first rolling element 1121 rolls in the first guide groove 111, and the second rolling element 1221 rolls in the second guide groove 121, which can reduce the frictional resistance of the movement of the needle bed 20, reduce the generation of debris, and improve the smoothness of the movement of the needle bed 20.

[0208] For example, the first rolling element 1121 and the second rolling element 1221 may be cam bearing followers, which is beneficial to improving the smoothness of rolling.

[0209] Of course, in some other embodiments, the first moving member 112 may include the first rolling member 1121 , while the second moving member 122 may not include the second rolling member 1221 , and may cooperate with the second guide groove 121 by sliding or the like.

[0210] In some other embodiments, the second moving member 122 may include the second rolling member 1221 , while the first moving member 112 may not include the first rolling member 1121 , and may cooperate with the second guide groove 121 by sliding or the like.

[0211] In some other embodiments, the first moving member 112 may be slidably fitted to the first guide member 11 , and the second moving member 122 may also be slidably fitted to the second guide member 12 .

[0212] Optionally, referring to Figures 4, 6, and 8, a first reinforcing member 113 is further provided on one of the first guide member 11 and the needle bed 20 on which the first movable member 112 is provided, and the first movable member 112 is fixedly mounted on the first reinforcing member 113. A second reinforcing member 123 is further provided on one of the second guide member 12 and the needle bed 20 on which the second movable member 122 is provided, and the second movable member 122 is fixedly mounted on the second reinforcing member 123.

[0213] Such a setting can improve the connection strength between the first moving member 112 and the first guide member 11 or needle bed 20 to which it is connected, and reduce the possibility of damage to the connection between the first moving member 112 and the first guide member 11 or needle bed 20 due to stress concentration; and can improve the connection strength between the second moving member 122 and the second guide member 12 or needle bed 20 to which it is connected, and reduce the possibility of damage to the connection between the second moving member 122 and the second guide member 12 or needle bed 20 due to stress concentration.

[0214] Alternatively, please refer to Figures 2 and 11. Figure 11 shows a case where two needle bed assemblies 100 are arranged side by side. When the two needle bed assemblies 100 are arranged side by side, the first guide member 11 of one needle bed assembly 100 can be connected to or integrally arranged with the second guide member 12 of the other needle bed assembly 100. Figures 2 and 11 exemplarily show a case where the first guide member 11 of one needle bed assembly 100 is integrally arranged with the second guide member 12 of the other needle bed assembly 100.

[0215] Of course, in some other embodiments, when two needle bed assemblies 100 are arranged side by side, the first guide member 11 of one needle bed assembly 100 may not be connected to the second guide member 12 of the other needle bed assembly 100 .

[0216] 3 and 4 , in some embodiments, the needle bed 20 can be moved away from the support member 10 in a first direction A to a withdrawn position, and can be moved toward the support member 10 in the first direction A to a retracted position. A positioning member 13 is provided on the support member 10 for positioning the needle bed 20 when the needle bed 20 moves to the retracted position.

[0217] It will be understood that the retracted position is a position in which the needle bed 20 and the positioning member 13 are in contact and positioned. For example, in the first direction A, the needle bed 20 and the support member 10 are approximately in the same position. The withdrawn position is a position in which the needle bed 20 is separated from the positioning member 13 and the needle bed 20 at least partially extends outside the support member 10. For example, in the first direction A, the needle bed 20 at least partially extends to one side of the support member 10 and is no longer in the same position as the support member 10. Therefore, the withdrawn position is not a fixed position and can be any position in which the needle bed 20 is separated from the positioning member 13 and at least partially extends outside the support member 10. Figure 3 exemplarily illustrates the situation in which the needle bed 20 is separated from the positioning member 13, which can be considered to be the withdrawn position.

[0218] The positioning member 13 refers to a structural member that can limit the needle bed 20 from continuing to move when the needle bed 20 moves from the pulled-out position to the pushed-back position, so as to position the needle bed 20. It can be a structure of various regular or irregular shapes, such as a block structure, a plate structure, a frame structure, etc., but is not limited to these.

[0219] With such arrangement, when the needle bed 20 moves from the withdrawn position to the pushed-back position, the needle bed 20 can be positioned by the positioning member 13, which helps the needle bed 20 to accurately move to the preset positioning position.

[0220] Optionally, referring to Figures 3 and 4 , a positioning member 13 may be provided at one end of the first guide member 11 of the support member 10. For example, the positioning member 13 may be located at one end of a first guide groove 111 on the first guide member 11. A positioning member 13 may be provided at one end of the second guide member 12 of the support member 10. For example, the positioning member 13 may be located at one end of a second guide groove 121 on the second guide member 12.

[0221] Please refer to Figures 4, 6 and 7. Figure 7 shows a schematic structural diagram of the positioning member 13 provided in some embodiments of the present application.

[0222] Optionally, in some embodiments, the positioning member 13 is provided with a contact portion 131 and a stop portion 132. The needle bed 20 is provided with a contact mating portion 1310 and a stop mating portion 1320. The contact mating portion 1310 is configured to frictionally contact the contact portion 131 when the needle bed 20 moves to the pushed-back position, and the stop mating portion 1320 is configured to abut against the stop portion 132 when the needle bed 20 moves to the pushed-back position.

[0223] It can be understood that the contact portion 131 and the contact matching portion 1310 cooperate to work together, and friction matching can be performed when the two are in contact (that is, there is friction between the two). The contact portion 131 and the contact matching portion 1310 can be various structures with regular or irregular shapes, such as surface structures, block structures, plate structures, protruding structures, etc., but are not limited to these. For example, when the needle bed 20 is in the pushed-back position, the contact matching portion 1310 can be located on the side of the needle bed 20, and the contact portion 131 is located on one side of the needle bed 20 and is in frictional contact with the contact matching portion 1310, which can provide a certain friction force for the movement of the needle bed 20. The contact portion 131 and the contact matching portion 1310 can be regarded as being arranged in sequence along a direction perpendicular to the first direction A.

[0224] The stop portion 132 cooperates with the stop mating portion 1320, abutting against each other when in contact, thereby restricting relative movement. The stop portion 132 and the stop mating portion 1320 may have various regular or irregular shapes, such as, but not limited to, block-shaped structures, plate-like structures, protruding structures, or surface structures. For example, when the needle bed 20 is in the pushed-back position, the stop mating portion 1320 may be located at one end of the needle bed in the first direction A. The stop mating portion 1320 and the stop portion 132 are arranged sequentially along the first direction A so that they abut against each other, restricting further movement of the needle bed 20 in the first direction A.

[0225] With such a configuration, when the needle bed 20 moves from the withdrawn position to the pushed-back position, the contact fitting portion 1310 can frictionally contact the contact portion 131, thereby cushioning the needle bed 20 and reducing the possibility of damage caused by the needle bed 20 quickly colliding with the positioning member 13, and limiting the arbitrary movement of the needle bed 20 (movement can only occur when the force on the needle bed 20 is greater than the friction force between the contact fitting portion 1310 and the contact portion 131); and the stop fitting portion 1320 can abut against the stop portion 132, limiting the needle bed 20 from continuing to move along the first direction A.

[0226] Optionally, referring to FIG. 4 , FIG. 6 and FIG. 7 , when the needle bed 20 is in the withdrawn position, the contact portion 131 is located on the side of the stop portion 132 facing the needle bed 20 .

[0227] With such arrangement, when the needle bed 20 moves from the pulled-out position to the pushed-back position, the contact fitting portion 1310 may first frictionally contact the contact portion 131, and then the stop fitting portion 1320 may abut against the stop portion 132. Compared with the contact portion 131 being located on the side of the stop portion 132 facing away from the needle bed 20, the contact fitting portion 1310 may not need to extend outward to contact and fit with the contact portion 131 located on the side of the stop portion 132 facing away from the needle bed 20, and the size may not need to be set too large, which is conducive to simplifying the structure of the contact fitting portion 1310 and the stop fitting portion 1320.

[0228] Of course, the relative positions of the contact portion 131 and the stop portion 132 are not limited to this. In other embodiments, when the needle bed 20 is in the pulled-out position, the contact portion 131 may also be located on the side of the stop portion 132 facing away from the needle bed 20, and the contact portion 131 may also be in approximately the same position as the stop portion 132.

[0229] 4 , 6 and 7 , the positioning member 13 is further provided with a first guide portion 133. When the needle bed 20 is in the withdrawn position, the first guide portion 133 is located on the side of the contact portion 131 facing the needle bed 20 and is used to guide the contact mating portion 1310 to move into frictional contact with the contact portion 131.

[0230] It is understood that the first guide portion 133 is a structure that can guide the movement of an object, and can be, for example, a slope, a curved surface, an inclined line, or an arc-shaped line structure. FIG7 exemplarily shows the case where the first guide portion 133 is an inclined surface.

[0231] In this arrangement, when the needle bed 20 moves from the pulled-out position to the pushed-back position, the contact fitting portion 1310 on the needle bed 20 can first contact the first guide portion 133, and continue to move to frictional contact with the contact portion 131 under the guidance of the first guide portion 133, and can buffer the movement of the needle bed 20, thereby reducing the force or possibility of the contact fitting portion 1310 directly colliding with the positioning member 13.

[0232] Please refer to Figures 3, 4 and 6. In some embodiments, at least one load-bearing member 14 is provided on the support component 10. The load-bearing member 14 has a limiting portion 141. The limiting portion 141 is located on one side of the needle bed 20 in the height direction H of the needle bed 20, and is used to limit the upward movement of the needle bed 20 along the height direction H.

[0233] It is understood that the load-bearing member 14 refers to a structural member capable of bearing force and can be of various regular or irregular shapes, such as, but not limited to, a plate-like structure, a block-like structure, a bracket structure, or a rod-like structure. The limiting portion 141 is a portion of the load-bearing member 14 and can be of various shapes, such as, but not limited to, a plate-like structure, a rod-like structure, or a block-like structure. Figures 3 and 4 exemplify the case where the load-bearing member 14 is a bent block-like structure, generally L-shaped or T-shaped.

[0234] With this arrangement, when the needle bed 20 is forced to move relative to the support member 10, it will contact the limiting portion 141, thereby restricting further movement of the needle bed 20. For example, when the formation device 1000 drives the battery to move so that the battery moves into electrical contact with the needle bed 20, the needle bed 20 will be subjected to the force applied by the battery and move along its own height direction. The load-bearing member 14 and its limiting portion 141 can limit the position of the needle bed 20, thereby improving the stability of the needle bed 20.

[0235] For example, referring to Figures 3, 4 and 6, at least one load-bearing member 14 can be provided on each of the first guide member 11 and the second guide member 12 of the support component 10, so that the needle bed 20 can be limited on opposite sides of the needle bed 20, which is beneficial to improving the reliability of the limitation. Figures 3, 4 and 6 exemplarily show the situation where three load-bearing members 14 are provided on each of the first guide member 11 and the second guide member 12. The three load-bearing members 14 on the first guide member 11 are respectively provided at the two ends and the middle of the first guide member 11, and the three load-bearing members 14 on the second guide member 12 are respectively provided at the two ends and the middle of the second guide member 12, so as to limit the two ends and the middle position of the needle bed 20, which is beneficial to improving the reliability of limiting the needle bed 20.

[0236] Optionally, in some embodiments, refer to Figures 3, 4 and 6, at least one pad 201 is provided on the needle bed 20. When the needle bed 20 moves along the first direction A toward the support component 10 to the pushed-back position, the pad 201 corresponds one-to-one with the load-bearing component 14, and the pad 201 is located between the needle bed 20 and the limiting portion 141.

[0237] It is understood that the cushion member 201 is a structural member used to cushion between the needle bed 20 and the stopper 141. It can be of various regular or irregular shapes, such as, but not limited to, a block-shaped structure, a plate-shaped structure, or a columnar structure. Since the cushion members 201 correspond one-to-one with the load-bearing members 14 when the needle bed 20 moves toward the support member 10 in the first direction A to the pushed-back position, the number of cushion members 201 is the same as the number of load-bearing members 14, and the positions of the cushion members 201 correspond to the positions of the load-bearing members 14. A space is formed between the stopper 141 and the needle bed 20 for the load-bearing members 14 to be accommodated.

[0238] With such arrangement, when the needle bed 20 is in the pushed-back position, the cushion 201 is located between the limiting portion 141 and the needle bed 20. If the needle bed 20 is subjected to force (for example, it is electrically in contact with the battery and is subjected to force applied by the battery) and moves along its own height direction H, the cushion 201 abuts against the limiting portion 141; when the needle bed 20 moves along the first direction A relative to the supporting component 10, the cushion 201 can be separated from the limiting portion 141. Compared with the solution in which the cushion 201 is not provided and the needle bed 20 directly cooperates with the limiting portion 141, the resistance generated by friction between the needle bed 20 and the limiting portion 141 can be reduced, which is conducive to improving the smoothness of the movement of the needle bed 20.

[0239] For example, referring to Figures 3, 4 and 6, when at least one load-bearing member 14 is provided on the first guide member 11 and the second guide member 12 of the support component 10, at least one pad 201 is also provided on the opposite sides of the needle bed 20, so that the pads 201 located on both sides of the needle bed 20 can be used to cooperate with the load-bearing member 14 on the first guide member 11 and the load-bearing member 14 on the second guide member 12, respectively.

[0240] Please refer to Figures 6 and 8 , Figure 8 is a partial enlarged view of point D in Figure 6 . Optionally, a second guide portion 2010 is provided on the cushion 201 , and the second guide portion 2010 is used to guide and cooperate with the limiting portion 141 .

[0241] It is understood that the second guide portion 2010 is a structure capable of guiding the movement of an object, and may be, for example, a sloped surface, an arcuate surface, an inclined line, or an arc-shaped line. Figure 8 exemplifies an example of the second guide portion 2010 being an inclined surface, wherein the second guide portion 2010 is tilted downwardly toward the needle bed 20. Because the second guide portion 2010 is intended to cooperate with the stopper 141 for guidance, it is located on the side of the cushion member 201 facing away from the needle bed 20. This allows the cushion member 201 to cooperate with the stopper 141 when the cushion member 201 moves along the first direction A with the needle bed 20, thereby facilitating smooth movement of the cushion member 201 between the stopper 141 and the needle bed 20.

[0242] With this arrangement, when the needle bed 20 moves along the first direction A, the second guide portion 2010 can guide and cushion the movement of the cushion 201 relative to the limiting portion 141, thereby reducing the force or possibility of the cushion 201 directly colliding with the limiting portion 141.

[0243] Optionally, referring to FIG. 8 , the cushion 201 is provided with second guiding portions 2010 at two opposite ends in the first direction A, respectively.

[0244] In this way, during the process of pulling out the needle bed 20 relative to the support part 10 along the first direction A, the second guide part 2010 at one end of the cushion 201 can be guided and cooperated with the limiting part 141. During the process of pushing the needle bed 20 back relative to the support part 10 along the second direction B, the second guide part 2010 at the other end of the cushion 201 can be guided and cooperated with the limiting part 141. Therefore, during the process of pulling out and pushing back the needle bed 20, the movement of the cushion 201 relative to the limiting part 141 can play a guiding and buffering role.

[0245] Optionally, in some embodiments, please refer to Figures 4 and 6, a first through hole 1410 is provided on the limiting portion 141 of at least one load-bearing member 14, and the needle bed assembly 100 also includes a first locking member 40, which is movably disposed in the first through hole 1410 and is used to connect with the needle bed 20.

[0246] It is understood that the first locking member 40 is a structural member that performs a fastening or locking function, and can be, for example, various types of fasteners (such as, but not limited to, screws, bolts, and pins), or a retaining member. The first locking member 40 can be inserted into the first through hole 1410 in various movable ways to enable movement relative to the limiting portion 141.

[0247] This arrangement, with the first locking member 40 inserted through the first through-hole 1410 and connected to the needle bed 20, helps to fix the relative position of the load-bearing member 14 and the needle bed 20, thereby restricting the movement of the needle bed 20 relative to the support member 10 in the first direction A, thereby improving the stability of the needle bed 20 in operation. By separating the first locking member 40 from the needle bed 20, the needle bed 20 can move relative to the support member 10.

[0248] Optionally, the first through hole 1410 may be a threaded hole, and the first locking member 40 may be threadedly engaged with the first through hole 1410 . The inner wall of the threaded hole is provided with an internal thread, and the outer wall of the first locking member 40 is correspondingly provided with an external thread.

[0249] In this arrangement, by screwing the first locking member 40 so that the first locking member 40 moves closer to the needle bed 20 and abuts against the needle bed 20, the needle bed 20 can be limited from moving along the first direction A relative to the load-bearing member 14 through the abutting force and friction between the first locking member 40 and the needle bed 20.

[0250] It should be noted that the engagement between the first locking member 40 and the first through hole 1410 is not limited to this. In other embodiments, after the first locking member 40 is inserted into the first through hole 1410, it can be threadedly connected, snap-fitted, or plug-fitted with the needle bed 20 (the needle bed 20 can be provided with a socket), or the relative position between the needle bed 20 and the load-bearing member 14 can be fixed. In this case, the first through hole 1410 can be a blank hole.

[0251] For example, when a pad 201 is provided on the needle bed 20, when the needle bed 20 moves along the first direction A toward the support component 10 to the pushed-back position, the pad 201 corresponds one-to-one with the load-bearing component 14, and by connecting the first locking component 40 with the pad 201, the needle bed 20 can be restricted from moving along the first direction A relative to the support component 10.

[0252] Optionally, in some embodiments, referring to FIG. 3 and FIG. 4 , the needle bed assembly 100 further includes an adjustment mechanism 50 , which is disposed on the needle bed 20 and is used to adjust the position of the needle bed 20 relative to the support component 10 .

[0253] It can be understood that the adjustment mechanism 50 is a mechanism that can adjust the position of the needle bed 20 relative to the support component 10. It can be a manual adjustment mechanism (for example, a bolt adjustment mechanism, a screw adjustment mechanism, etc., but not limited to this), or an automatic adjustment mechanism (for example, a linear motor, a mechanism composed of a motor and mechanical components, etc., but not limited to this).

[0254] With this arrangement, the adjustment mechanism 50 can be operated to move the needle bed 20 relative to the support member 10, thereby adjusting the position of the needle bed 20 relative to the support member 10. For example, when the formation apparatus 1000 is performing formation and / or capacitance separation on a battery, the adjustment mechanism 50 can be used to adjust the position of the needle bed 20 relative to the support member 10 so that the position of the probes of the needle bed 20 is aligned with the position of the battery, thereby improving the accuracy of the electrical contact between the needle bed 20 and the battery.

[0255] Please refer to Figures 6 and 9, with Figure 9 being a partial enlarged view of point E in Figure 6. Optionally, the adjustment mechanism 50 includes a mounting member 51 and an adjustment member 52. The mounting member 51 is disposed on the needle bed 20; the adjustment member 52 is adjustably disposed on the mounting member 51, with one end of the adjustment member 52 being configured to abut against the load-bearing member 14 or the support member 10.

[0256] It is understood that the mounting member 51 is a component used to provide support and mounting for the adjusting member 52, and can be various structures with regular or irregular shapes, such as a plate-like structure, a block-like structure, etc., but not limited thereto. The adjusting member 52 is a structural member that can move relative to the mounting member 51, and can be various structures with regular or irregular shapes, such as a rod-like structure, a columnar structure, a block-like structure, etc., but not limited thereto. The adjusting member 52 being adjustably disposed on the mounting member 51 means that the adjusting member 52 is disposed on the mounting member 51 in a manner that allows it to move relative to the mounting member 51, such as by a threaded connection, a snap-fit ​​fit, etc., but not limited thereto.

[0257] In this arrangement, by applying force to the adjusting member 52, the adjusting member 52 is moved relative to the mounting member 51, and at the same time the adjusting member 52 abuts against the load-bearing member 14 or the supporting component 10 to drive the needle bed 20 to move relative to the load-bearing member 14 or the supporting component 10. The structure of the adjusting mechanism 50 is simple and is conducive to fine-tuning.

[0258] Optionally, a threaded hole may be provided on the mounting member 51 , and the adjusting member 52 may be threadedly engaged with the threaded hole on the mounting member 51 . For example, the adjusting member 52 may be a bolt, a screw, etc., but is not limited thereto.

[0259] With such arrangement, by screwing the adjusting member 52 , the adjusting member 52 can be moved relative to the mounting member 51 , thereby adjusting the needle bed 20 to move relative to the load-bearing member 14 , which makes the adjustment convenient.

[0260] Optionally, referring to Figures 4 and 6, the mounting member 51 can be arranged on the pad 201 located at one end of the needle bed 20, which facilitates the arrangement of the mounting member 51, improves the structural compactness of the mounting member 51 and the pad 201, and facilitates the adjustment member 52 to abut against the load-bearing member 14.

[0261] Optionally, when load-bearing members 14 are provided on both the first guide member 11 and the second guide member 12 of the support member 10, and pads 201 are provided on opposite sides of the needle bed 20, an adjustment mechanism 50 is provided on the pad 201 at the pulled-out end of one side of the needle bed 20, and an adjustment mechanism 50 is also provided on the pad 201 at the pulled-out end of the other side of the needle bed 20. The two adjustment mechanisms 50 can be adjusted simultaneously, which is conducive to improving the accuracy of the adjustment.

[0262] In some embodiments, power supply assembly 30 is a DC / DC power supply assembly, i.e., a power supply assembly that converts direct current to direct current. It can be any type of DC / DC power supply assembly, where DC stands for Direct Current. The DC / DC power supply assembly can include one or more DC / DC power modules.

[0263] This arrangement allows the DC / DC power supply assembly to generate less heat and interfere less with other components than an AC / DC power supply assembly, allowing it to be integrated with the needle bed 20 and housed in the same space. The AC / DC power supply assembly converts alternating current (AC) to direct current (DC) and can be any type of AC / DC power supply assembly. AC stands for Alternating Current.

The power module 31 can be disposed on the needle bed 20 in a variety of detachable connection methods, such as, but not limited to, connection via fasteners (such as screws, bolts, etc.), connection via a snap-fit ​​structure, etc.

[0266] With such configuration, the power supply assembly 30 is a split structure including multiple power modules 31 , which facilitates maintenance or replacement of one or more of the power modules 31 , and facilitates maintenance and replacement of the power supply assembly 30 .

[0267] Please refer to FIG. 4 , FIG. 6 and FIG. 10 . FIG. 10 shows a schematic structural diagram of the first support member 211 and the second support member 212 .

[0268] In some embodiments, the needle bed 20 includes a first support member 211, a second support member 212, and a third support member 213. The second support member 212 is spaced apart from the first support member 211. The third support member 213 is connected to the first support member 211 and the second support member 212. The first support member 211 and the second support member 212 are movably disposed on the support member 10 along a first direction A, and the power supply assembly 30 is disposed on the third support member 213.

[0270] In this arrangement, the first support member 211 , the second support member 212 and the third support member 213 are connected to form a frame structure, which can serve as a support base for the needle bed 20 for installing other components of the needle bed 20 , and also facilitates the installation of the power supply assembly 30 .

[0271] Optionally, in some embodiments, referring to FIG. 4 and FIG. 6 , the third support member 213 is located in a space formed between the first support member 211 and the second support member 212 .

[0272] Such an arrangement, compared with the third support member 213 being stacked on the first support member 211 and the second support member 212 along the height direction of the needle bed assembly 100, can reduce the overall height formed by the first support member 211, the second support member 212 and the third support member 213, which is beneficial to reduce the overall height of the needle bed assembly 100, thereby reducing the height of the formation device 1000.

[0273] Please refer to Figure 11. In some embodiments, the needle bed 20 includes a support body 21 and a probe mechanism 22. The support body 21 can be movably arranged on the support component 10 along the first direction A; the probe mechanism 22 is arranged on the support body 21; wherein, the power supply component 30 is arranged on the support body 21.

[0274] It is understood that the support body 21 is a supporting structure of the needle bed 20 and can be a structure of various shapes, such as a frame structure, a bracket structure, etc., but is not limited thereto. For example, the support body 21 can include the first support member 211, the second support member 212, and the third support member 213 described above.

There can be one or more probe mechanisms 22. Figure 11 exemplifies a needle bed 20 with two probe mechanisms 22, for example, one for electrically contacting the positive and one for contacting the negative terminals of a battery.

[0276] With such configuration, the support body 21 can provide support for the probe mechanism 22 and the power supply assembly 30 , thereby facilitating the installation and placement of the probe mechanism 22 and the power supply assembly 30 .

[0277] Optionally, in some embodiments, referring to FIG11 , the probe mechanism 22 is movably disposed on the support body 21 along a second direction B relative to the support body 21. The second direction B forms an angle with the first direction A, that is, the second direction B is neither parallel to nor coincident with the first direction A, and an angle greater than 0° is formed therebetween.

[0278] It is understood that the probe mechanism 22 can be provided on the support body 21 through a variety of movable connection methods, such as sliding fit, rolling fit, etc., but not limited thereto, as long as the probe mechanism 22 can move relative to the support body 21 along the second direction B. The second direction B can be any linear direction intersecting with the first direction A, such as the width direction of the support body 21, but not limited thereto.

[0279] With this arrangement, the position of the probe mechanism 22 can be adjusted by moving the probe mechanism 22 relative to the support body 21 along the second direction B, so as to adapt to the position of the poles of batteries of different sizes or types for electrical contact with the batteries.

[0280] Please refer to Figure 12, which is a partial enlarged view of point F in Figure 11. Optionally, the needle bed 20 further includes a guide portion 23 and a sliding portion 24; the guide portion 23 is disposed on the support body 21 and extends along the second direction B; the sliding portion 24 slidably engages with the guide portion 23; wherein the probe mechanism 22 is disposed on the sliding portion 24.

[0281] It is understood that the guide portion 23 is a structure that guides the movement of the sliding portion 24, and may be, for example, a guide rail (such a case is exemplarily shown in FIG12 ), a guide bar, a guide plate, etc., but is not limited thereto. The sliding portion 24 is a structure that can slide relative to the guide portion 23, and may be various regular or irregular structures, such as a slider structure (such a case is exemplarily shown in FIG12 ), a slide rail structure, etc., but is not limited thereto.

[0282] With such arrangement, the probe mechanism 22 can move on the guide portion 23 via the sliding portion 24 , which helps to improve the stability and reliability of the movement of the probe mechanism 22 .

[0283] Please refer to Figures 11 to 13 , where Figure 13 is a partial enlarged view of point G in Figure 11 . Optionally, in some embodiments, the probe mechanism 22 includes a probe mounting member 221 and a plurality of probes 222 ; the probe mounting member 221 is disposed on the support 21 ; and each probe 222 is sequentially disposed on the probe mounting member 221 .

[0284] It will be understood that probe mounting member 221 is a structural member used to support and mount probe 222. It can be of various shapes, such as, but not limited to, a strip, plate, or block. Probe 222 is an actuator for direct electrical contact with the battery and can be of various types. Probe 222 can be electrically connected to power supply assembly 30, for example, via a wire or cable.

[0285] With such configuration, the probe mounting member 221 can simultaneously provide support and mounting for a plurality of probes 222 , and the plurality of probes 222 can respectively make electrical contact with the battery poles.

[0286] 11 and 13 , the probe mounting member 221 is provided with a plurality of mounting portions 2211, and the probes 222 correspond one to one with the mounting portions 2211, i.e., one probe 222 is provided on each mounting portion 2211. The mounting portion 2211 includes a plurality of sub-mounting portions 22111, and one probe 222 corresponding to the mounting portion 2211 is selectively provided on the sub-mounting portion 22111.

[0287] It is understood that the mounting portion 2211 is the specific portion of the probe mounting member 221 where the probe 222 can be mounted, and can have various structures, such as a mounting groove structure (which is exemplarily shown in FIG13 ), a protrusion structure, a latching structure, etc., but is not limited thereto. The sub-mounting portion 22111 is a portion of the mounting portion 2211, and each sub-mounting portion 22111 can be used to mount a probe 222.

[0288] With this arrangement, the probe 222 can be selectively installed on any sub-mounting portion 22111 of the corresponding mounting portion 2211. When the probe 222 is installed on different sub-mounting portions 22111, it is in different positions. Therefore, the position of the probe 222 on the probe mounting member 221 is adjustable and can adapt to batteries of different types or sizes.

[0289] 13 , the probe mechanism 22 further includes a plurality of identification portions 223 , each corresponding to the mounting portion 2211 . The identification portion 223 includes a plurality of sub-identification portions 2231 , each corresponding to the sub-mounting portion 22111 .

[0290] It is understood that the identification portion 223 can be various identifications, such as, but not limited to, a label, scale, or mark. The sub-identification portion 2231 is a part of the identification portion 223 and can be a part of a label, scale, or mark.

[0291] With such arrangement, the probe 222 can be installed on the corresponding sub-mounting portion 22111 according to the identification, which is beneficial to improving the accuracy and convenience of the installation of the probe 222.

[0292] 13 , the probe mechanism 22 further includes a probe side guard plate 224, which is disposed on the probe mounting member 221. It can be understood that the probe side guard plate 224 is a substantially plate-shaped structure.

[0293] With this configuration, the probe side shield 224 can provide protection for the probe 222 and reduce the possibility of the probe 222 being disturbed by external factors.

[0294] Optionally, referring to FIG. 13 , at least one through hole is provided on the probe side shield 224 to facilitate air flow and thus heat dissipation.

[0295] Please refer to FIG14 , which is a partial enlarged view of point H in FIG2 . Optionally, in some embodiments, the needle bed 20 further includes a locking mechanism 25 , which is used to limit the movement of the probe mechanism 22 relative to the support body 21 .

[0296] It can be understood that the locking mechanism 25 is a mechanism that can lock the movement of the probe mechanism 22 relative to the support body 21. It can be various types of locking mechanisms 25, such as an adjustable mechanism, a fastener locking mechanism (such as a bolt or screw, etc.), etc., but is not limited to this.

[0297] With this arrangement, after the probe mechanism 22 is adjusted to move to a desired position relative to the support body 21, it can be locked by the locking mechanism 25 to limit the movement of the probe mechanism 22, which is beneficial to improving the position stability of the probe mechanism 22 and further improving the reliability of electrical contact with the battery.

[0298] Please refer to Figures 14 and 15 . Figure 15 shows an exploded schematic diagram of the locking mechanism 25. Optionally, the locking mechanism 25 includes a locking portion 251, a movable member 252, and a locking engagement portion 253. The locking portion 251 is disposed on the support body 21; the movable member 252 is movably disposed on the probe mechanism 22; and the locking engagement portion 253 is disposed on the movable member 252 and is configured to engage with the locking portion 251.

[0299] It can be understood that the locking portion 251 and the locking matching portion 253 are used to connect and cooperate with each other to perform a locking function. The two can be various structures that can limit the relative movement of the two when connected, such as meshing tooth structures, locking structures, plug-in structures, etc., but are not limited to these.

[0300] The movable member 252 is a structural member that can move relative to the probe mechanism 22 and can be a structure of various regular or irregular shapes, such as a block structure, a plate structure, etc., but is not limited thereto.

[0301] In this arrangement, by moving the movable part 252, the movable part 252 can drive the locking fitting part 253 to move, so that the locking fitting part 253 is locked and fitted with or separated from the locking part 251. When it is necessary to adjust the movement of the probe mechanism 22 relative to the support body 21, the movable part 252 is moved to separate the locking fitting part 253 from the locking part 251. After the position adjustment of the probe mechanism 22 relative to the support body 21 is completed, the movable part 252 is moved to lock and fit the locking fitting part 253 with the locking part 251.

[0302] For example, referring to FIG. 14 and FIG. 15 , the movable member 252 can be movably disposed on the probe mounting member 221 of the probe mechanism 22 .

[0303] Optionally, referring to Figures 14 and 15, the locking portion 251 can be a tooth structure, for example, it can include a plurality of bar teeth arranged in sequence along the second direction B; accordingly, the locking fitting portion 253 is also a tooth structure, for example, it can include a plurality of bar teeth arranged in sequence along the second direction B; by engaging the locking fitting portion 253 with the locking portion 251, the probe mechanism 22 can be restricted from moving along the second direction B.

[0304] The tooth pitch of the locking portion 251 (the distance between two adjacent bar teeth) can be greater than or equal to the tooth pitch of the locking fitting portion 253, and be an integer multiple of the tooth pitch of the locking fitting portion 253, so as to facilitate the engagement of the locking portion 251 with the locking fitting portion 253.

[0305] Optionally, referring to FIG. 14 and FIG. 15 , the locking mechanism 25 further includes an elastic member 254 , which is connected to the movable member 252 and is used to provide a force to move the locking engagement portion 253 on the movable member 252 toward the locking portion 251 .

[0306] It can be understood that the elastic member 254 is a structural member that can undergo elastic deformation, for example, it can be a spring, a reed, a rubber spring, etc., but is not limited thereto.

[0307] With this arrangement, the elastic member 254 continuously provides a force to move the locking engagement portion 253 on the movable member 252 toward the locking portion 251 , so that the locking engagement portion 253 and the locking portion 251 can be continuously locked and engaged without being affected by external forces, which is beneficial to improving the locking effect.

[0308] Optionally, referring to Figures 14 and 15, the locking mechanism 25 also includes a fixing member 255, which is arranged on the probe mechanism 22. The fixing member 255 has a limiting section 2551, and a movable through hole 25510 is opened on the limiting section 2551. The movable member 252 includes a movable portion 2521, a flange portion 2522 and a pressing portion 2523, and the movable portion 2521 can be movably passed through the movable through hole 25510. The flange portion 2522 is arranged on the movable portion 2521 and is spaced apart from the limiting section 2551. The elastic member 254 is located between the flange portion 2522 and the limiting section 2551. The pressing portion 2523 is arranged on the movable portion 2521 and is located on the side of the limiting section 2551 away from the elastic member 254. The locking fitting portion 253 is arranged on the pressing portion 2523.

[0309] It is understood that the fixing member 255 is a structural member used to support the movement of the movable member 252 and can have various shapes, such as, but not limited to, a block structure or a bracket structure. The fixing member 255 can be fixed to the probe mechanism 22 in various ways, such as, but not limited to, screws or bolts, welding, or snap-fitting. The limiting section 2551 is part of the fixing member 255 and can have various shapes. It is used to limit the movement of the elastic member 254, the movable portion 2521, and the pressing portion 2523.

[0310] The movable portion 2521 is a structure that can move relative to the fixed member 255 and can be of various shapes, such as a rod-shaped structure (such a situation is exemplarily shown in FIG15 ), a strip-shaped structure, etc., but is not limited thereto. The flange portion 2522 is a structure that protrudes from the movable portion 2521 and can be of various shapes, such as a ring-shaped protruding structure (such a situation is exemplarily shown in FIG15 ), a rod-shaped protruding structure, etc., but is not limited thereto. The pressing portion 2523 is used to lock the fitting portion 253 so that the locking fitting portion 253 can be pressed onto the locking portion 251. The pressing portion 2523 can be a structure of various regular or irregular shapes, such as a block-shaped structure (such a situation is exemplarily shown in FIG15 ), a plate-shaped structure, etc., but is not limited thereto.

[0311] In this arrangement, by applying force to the movable part 2521, the movable part 2521 moves away from the locking part 251 relative to the limiting section 2551, and the movable part 2521 drives the flange part 2522 to move close to the limiting section 2551 to apply force to the elastic part 254, and the elastic part 254 is limited between the flange part 2522 and the limiting section 2551 and applies a reaction force to the flange part 2522; at the same time, when the movable part 2521 moves, the clamping part 2523 moves accordingly, and the clamping part 2523 can drive the locking matching part 253 to move so that the locking matching part 253 is separated from the locking part 251, so that the position of the probe mechanism 22 relative to the support body 21 can be adjusted.

[0312] When the force applied to the movable part 2521 is removed, the flange part 2522 can move away from the limiting section 2551 under the action of the elastic potential energy of the elastic member 254, and the flange part 2522 drives the movable part 2521 and the clamping part 2523 to move closer to the locking part 251, and the locking matching part 253 is locked with the locking part 251, thereby locking the position of the probe mechanism 22 relative to the support body 21.

[0313] For example, referring to FIG. 14 and FIG. 15 , the fixing member 255 may be fixedly disposed on the probe mounting member 221 of the probe mechanism 22 .

[0314] Optionally, referring to FIG. 15 , a limiting portion 25511 is provided on the inner wall of the movable through hole 25510 , and a limiting matching portion 25211 is provided on the movable portion 2521 . The limiting portion 25511 cooperates with the limiting matching portion 25211 to limit the movable portion 2521 from rotating in the movable through hole 25510 .

[0315] It is understood that the limiting portion 25511 and the limiting mating portion 25211 cooperate to provide a limiting function, and can be a combination of various structural forms, such as a planar structure combined with a planar structure, or a protruding structure combined with a recessed structure, but are not limited thereto. FIG15 exemplarily illustrates a case where both the limiting portion 25511 and the limiting mating portion 25211 are planar structures, whereby the movable through hole 25510 is formed as a non-circular hole, and the outer contour of the cross section of the movable portion 2521 is also non-circular, thereby limiting the rotation of the movable portion 2521 within the movable through hole 25510.

[0316] With such a configuration, the movable portion 2521 can move in the movable through hole 25510 along the axial direction of the movable through hole 25510 , while limiting the movable portion 2521 from rotating in the movable through hole 25510 , thereby improving the stability of the movement of the pressing portion 2523 .

[0317] Optionally, referring to FIG15 , an unlocking through hole 2201 is provided on the probe mechanism 22 , and the movable member 252 has an unlocking portion 2524 , which is movably inserted into the unlocking through hole 2201 from one end thereof and extends to the outside from the other end thereof.

[0318] It can be understood that the unlocking portion 2524 can be a structure of various shapes, which is used to move under force to move the movable member 252 as a whole.

[0319] In this arrangement, by applying force to one end of the unlocking portion 2524 extending to the outside of the unlocking through hole 2201 to push the movable part 252, so that the movable part 252 drives the locking fitting portion 253 to move away from the locking portion 251, so that the locking fitting portion 253 is separated from the locking portion 251, unlocking can be achieved, which is conducive to the movement of the probe mechanism 22 relative to the support body 21.

[0320] For example, referring to FIG. 14 and FIG. 15 , the unlocking through hole 2201 may be provided on the probe mounting member 221 of the probe mechanism 22 .

[0321] Optionally, in some embodiments, referring to Figure 12, the needle bed 20 further includes a ruler 26, which is disposed on the support body 21. It is understood that the ruler 26 can be a ruler in various forms.

[0322] With this arrangement, when the probe mechanism 22 is moved relative to the support body 21 , the scale 26 can be observed to facilitate quantification of the moving distance of the probe mechanism 22 , thereby improving the accuracy of the movement of the probe mechanism 22 .

[0323] Optionally, referring to FIG. 12 , the needle bed 20 further includes a pointer 27 . The pointer 27 is disposed on the probe mechanism 22 , and a needle end 271 of the pointer 27 is located on one side of the scale 26 .

[0324] In this way, the pointer 27 , in conjunction with the scale 26 , can more intuitively determine the movement size of the probe mechanism 22 .

[0325] For example, the pointer 27 can be disposed on the probe mounting member 221 of the probe mechanism 22, with a needle end 271 of the pointer 27 extending toward the scale 26 and positioned on one side of the scale 26. When a step is formed between the probe mechanism 22 and the support body 21, the pointer 27 can be bent to accommodate the step. One end of the pointer 27 can be connected to the probe mechanism 22, and the other end of the pointer 27 can form a needle end 271 and be positioned on one side of the scale 26 to indicate the scale or mark of the scale 26.

[0326] Referring to FIG. 1 and FIG. 2 , in some embodiments, the formation apparatus 1000 further includes a press 200 , and the support component 10 is disposed on the press 200 .

[0327] It can be understood that the press 200 is a mechanism for carrying the battery so as to make the battery electrically contact with the needle bed 20. The press 200 can be various types of presses.

[0328] With such arrangement, when the battery needs to be formed and / or divided into different capacities, the battery can be supported by the press 200 so as to facilitate electrical contact between the battery and the needle bed 20 .

[0329] Alternatively, in some embodiments, referring to FIG2 , a press machine 200 includes a support assembly 210, a drive mechanism 220, and a supporting member 230. The drive mechanism 220 is disposed on the support assembly 210. The supporting member 230 is connected to the power output end of the drive mechanism 220. The support member 10 is disposed on the support assembly 210.

[0330] It can be understood that the support assembly 210 is a component for supporting the driving mechanism 220 and the supporting member 230, and can be a support assembly of various structural forms, such as a bracket structure, a frame structure, etc., but is not limited thereto.

[0331] The drive mechanism 220 is a power structure for driving the support member 230. It can be any type of power structure, such as, but not limited to, a cylinder drive mechanism, a motor screw drive mechanism, or a linear motor. The power output end of the drive mechanism 220 is its actuator end, which can drive the object connected to it to move.

[0332] The supporting member 230 is a structure for supporting batteries, and can be a structure of various structural forms capable of supporting batteries, such as a frame structure, a plate structure, etc., but is not limited thereto.

[0333] With this arrangement, when it is necessary to form and / or separate the capacity of a battery, the battery can be placed on the supporting member 230, and the driving mechanism 220 is activated to drive the supporting member 230 to move closer to the needle bed 20, thereby driving the supporting member 230 to simultaneously move the battery closer to the needle bed 20, so that the battery and the needle bed 20 are in electrical contact. After the formation and / or separation is completed, the driving mechanism 220 is activated to drive the supporting member 230 to move away from the needle bed 20, thereby driving the supporting member 230 to move the battery away from the needle bed 20, and the battery can be removed from the supporting member 230.

[0334] Optionally, referring to FIG. 2 , the press machine 200 includes a front end 2001 and a rear end 2002 arranged along a first direction A, and the rear end 2002 has an avoidance space 20020 for avoiding the needle bed 20 when the needle bed 20 is pulled out from the rear end 2002 .

[0335] It is understood that the front end 2001 refers to the end of the formation apparatus 1000 that faces the user (which can be a person or a machine) during operation, and is generally the end used to place batteries on the press 200. The rear end 2002 is the end of the formation apparatus 1000 that faces away from the user during operation. The front end 2001 and the rear end 2002 are both part of the press 200, referring to the ends of the press 200 in the first direction A, rather than specifically referring to end faces or ends.

[0336] With this arrangement, when the needle bed 20 needs to be withdrawn and moved relative to the support member 10 in the first direction A, it can be withdrawn from the rear end 2002 of the press 200. The avoidance space 20020 can provide clearance for the needle bed 20, for example, it can allow for the probe and other components of the needle bed 20 to be cleared when the needle bed 20 moves in the first direction A. When the formation device 1000 is in operation, the space facing the front end 2001 is generally where a user operates. If the needle bed 20 is withdrawn from the front end 2001, user operation may be affected. This is particularly true when multiple formation devices 1000 are stacked, where the needle beds 20 of one or more formation devices 1000 may need to be withdrawn for maintenance or debugging. If the needle bed 20 is withdrawn from the front end 2001, the user's operation may be interfered with. Therefore, withdrawing the needle bed 20 from the rear end 2002 is less likely to interfere with the user or the operation of other formation devices 1000.

[0337] Exemplarily, the front end 2001 may be the front end of the support assembly 210 of the press 200 , and the rear end 2002 may be the rear end of the support assembly 210 of the press 200 .

[0338] Optionally, the needle bed assembly 100 may further include a bracket 60, and the support component 10 is connected to the rear end 2002 through the bracket 60. Since the rear end 2002 has an avoidance space 20020, the support component 10 is supported by the bracket 60, so that the support of the support component 10 is not affected by the avoidance space 20020.

[0339] For example, the first guide member 11 and the second guide member 12 of the support component 10 may be connected to the rear end 2002 via a bracket 60 respectively.

[0340] Please refer to FIG. 1 . In some embodiments, the formation apparatus 1000 further includes a housing 300 , and the press 200 and the needle bed assembly 100 are disposed inside the housing 300 .

[0341] It can be understood that the housing 300 is a structure with an internal accommodation space and can be in various shapes, such as a rectangular parallelepiped shape.

[0342] In this arrangement, the shell 300 can protect the press 200 and the needle bed assembly 100, which is beneficial to improving the installation performance of the work. When multiple formation devices 1000 are stacked, the shell 300 of the formation device 1000 can be stacked on the shell 300 of another formation device 1000, which is beneficial to stacking.

[0343] For example, referring to FIG. 1 and FIG. 2 , when the formation device 1000 needs to be maintained, the following steps may be performed:

[0344] (1) Adjusting the first locking member 40 to enable the needle bed 20 to move relative to the support member 10;

[0345] (2) applying force to the needle bed 20 so that the needle bed 20 is withdrawn from the rear end 2002 relative to the support member 10 along the first direction A; for example, the needle bed 20 may be extended from the support member 10 by a length that accounts for 2 / 3 of the total length of the needle bed 20;

[0346] (3) The power supply assembly 30, probe mechanism 22 and other components can be disassembled, replaced or debugged;

[0347] (4) After the maintenance is completed, the needle bed 20 is pushed in the reverse direction so that the needle bed 20 moves from the withdrawn position to the pushed-in position;

[0348] (5) adjusting the adjustment mechanism 50 to adjust the position of the needle bed 20 relative to the support member 10 to a desired working position;

[0349] (6) Adjust the first locking member 40 to fix the position of the needle bed 20 relative to the position of the support member 10.

[0350] Will be appreciated that the quantity of formation device 1000 can be one or more, and when the quantity of formation device 1000 is a plurality of, each formation device 1000 can be stacked and arranged.Formation device 1000 can also comprise battery being formed and / or other parts required for subcapacity, and illustratively, formation device 1000 can also comprise AC / DC power assembly, and AC / DC power assembly can be positioned at the outside of needle bed assembly 100 or housing 300, and is electrically connected with DC / DC power assembly.Like this, the larger AC / DC power assembly of heating can be positioned at the outside of needle bed assembly 100 or housing 300 and is electrically connected with DC / DC power assembly.

[0351] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
