Description

Technical Field

[0001] This application relates to the field of battery processing technology, and in particular to a battery formation and capacity-building mechanism, apparatus and system. Background Technology

[0002] Hot-press formation is a process for treating lithium-ion batteries under high temperature and high pressure to improve energy density and cycle life. This process involves pressurizing the battery at high temperatures, utilizing the increased conductivity of the electrolyte at these conditions to achieve high-rate formation. After the initial manufacturing of the lithium battery, it needs to be categorized for capacity, i.e., screened and graded based on its capacity and performance (such as internal resistance).

[0003] Currently, existing formation and capacity testing equipment can only be adapted to specific types of batteries. Because different battery models have different orientations of terminals and / or filling ports, existing formation and capacity testing equipment cannot meet the processing requirements of steel-cased batteries with different terminal and / or filling port orientations. Utility Model Content

[0004] This application discloses a formation and capacity testing mechanism, apparatus, and system, which can adapt the formation and capacity testing equipment and system to the formation and capacity testing requirements of various types of steel-cased batteries, and has good versatility.

[0005] In a first aspect, this application discloses a formation and capacity testing mechanism, comprising: a first base; a first pressure-bearing structure, the first pressure-bearing structure being movably disposed on the first base along a first direction; a first probe assembly, the first probe assembly including a first mounting plate and a first probe body, the first mounting plate being movably disposed on the first base along a second direction, the first probe body being disposed on the first mounting plate, and the first probe body extending along the second direction; a transmission member, the transmission member having a first end and a second end opposite to each other, the first end being movably connected to the first pressure-bearing structure, and the second end being movably connected to the first mounting plate; the first pressure-bearing structure is configured to move along the first direction under the action of an external force, so that the transmission member drives the first mounting plate to move along the second direction, thereby causing the first probe body to contact or separate from the battery under test; wherein, the second direction is a horizontal direction, and the second direction intersects with the first direction.

[0006] In related technologies, a force is applied to the formation and capacity testing mechanism in a first direction, causing the mechanism to move along that direction to contact or separate from the battery under test. When testing batteries where the terminals and / or filling ports extend along a second direction intersecting the first direction, existing formation and capacity testing equipment and systems are incompatible, necessitating the use of alternative equipment and systems, resulting in high production costs. The formation and capacity testing mechanism provided in this application, when performing formation and capacity testing on the battery under test, applies a force to the first pressure-bearing structure of the mechanism. Since the first end of the transmission component is movably connected to the first pressure-bearing structure, and the second end is movably connected to the first mounting plate of the probe assembly, when the first pressure-bearing structure is subjected to force and moves along the first direction, the transmission component, which moves relative to the first pressure-bearing structure and the probe assembly, transmits the movement of the first pressure-bearing structure to the first mounting plate, thereby causing the first mounting plate to drive the first probe body to move along the second direction. In other words, by using the formation and capacity testing mechanism provided in this application, the first probe body can be moved along the second direction through the transmission component without changing the direction of the force of the original equipment, so as to adapt to the formation and capacity testing requirements of different types of batteries. Thus, the formation and capacity testing equipment and system can adapt to the formation and capacity testing requirements of various steel-cased batteries by switching between the existing formation and capacity testing mechanism and the formation and capacity testing mechanism provided in this application, thereby making the device, equipment and system equipped with the formation and capacity testing mechanism have good versatility.

[0007] In one possible implementation, the first pressure-bearing structure includes a second mounting plate and a pressure-bearing member. The second mounting plate is movably disposed on the first base along the first direction, and the first end is movably connected to the second mounting plate. The pressure-bearing member is disposed on the second mounting plate and is used to drive the second mounting plate to move along the first direction under the action of an external force, so that the second mounting plate pushes the probe assembly to move along the second direction through the transmission member.

[0008] The first pressure-bearing structure includes a second mounting plate and a pressure-bearing component. The second mounting plate is movably mounted on the base, and a transmission component is movably connected to the second mounting plate. The pressure-bearing component is mounted on the second mounting plate and moves the second mounting plate under external force. This avoids the second mounting plate being directly subjected to the forces of other structures in the chemical reaction and formulation equipment, reduces the impact of structural friction on the second mounting plate, and minimizes wear on the second mounting plate.

[0009] In one possible implementation, the pressure-bearing component is a roller, which is rotatably mounted on the second mounting plate, and the roller and the transmission component are spaced apart along the first direction.

[0010] By setting the pressure-bearing component as a roller, when there is a displacement between the structure that applies external force to the roller and the roller that forms an angle with the first direction, the roller can rotate under the action of the structure, avoiding the second mounting plate from swinging due to the above displacement, and thus avoiding the situation where the first probe body swings and causes the corresponding battery to be tested to be misaligned, thus affecting the test.

[0011] In one possible implementation, the transmission element is a connecting rod, with the first end rotatably connected to the second mounting plate and the second end rotatably connected to the first mounting plate.

[0012] By setting the transmission component as a linkage, with one end of the linkage rotatably connected to the first mounting plate and the other end rotatably connected to the second mounting plate, the motion along the first direction can be converted into motion along the second direction through linkage transmission. This simplifies the transmission structure inside the filling and dispensing mechanism to the greatest extent and reduces the manufacturing cost of the filling and dispensing mechanism.

[0013] In one possible implementation, the first base includes a first seat body and a second seat body, the first seat body being disposed on the second seat body along the first direction, the first pressure-bearing structure being movably disposed on the first seat body along the first direction to move closer to or further away from the second seat body along the first direction; the second seat body is provided with a first clearance groove along the first direction, the first mounting plate includes a first sub-plate and a second sub-plate disposed on the first sub-plate, the first sub-plate being movably disposed on the second seat body along the second direction, the second sub-plate being at least partially located in the first clearance groove, and the first probe body being disposed on the second sub-plate.

[0014] A first clearance groove is provided on the second body of the first base, and the second sub-plate of the first mounting plate is at least partially located in the first clearance groove, thereby improving the compactness of the internal structure of the separation and filling mechanism and facilitating the miniaturization design of the separation and filling mechanism.

[0015] In one possible implementation, the first base is provided with a second clearance groove along the second direction, the second clearance groove communicating with the first clearance groove along the first direction, and the first sub-plate is at least partially located in the second clearance groove along the second direction to move in the second clearance groove along the first direction.

[0016] A second clearance groove is provided in the first seat of the first base, so that the first sub-plate of the first mounting plate is at least partially located in the second clearance groove, thereby improving the compactness of the internal structure of the separation and filling mechanism and facilitating the miniaturization design of the separation and filling mechanism.

[0017] In one possible implementation, the probe assembly further includes a first suction component disposed on the first mounting plate, the first suction component being used to vent the battery under test.

[0018] A first suction component is set on the first mounting plate of the probe assembly. The first suction component is used to vent the battery under test, that is, to remove the air inside the battery by the first suction component, so as to avoid the presence of air inside the battery and thus reduce the probability of battery fire.

[0019] In one possible implementation, the probe assembly further includes a first fixing seat and a second fixing seat, wherein the first probe body is disposed on the first fixing seat and the first suction component is disposed on the second fixing seat; the first mounting plate is provided with a plurality of spaced-apart first mounting portions and a plurality of spaced-apart second mounting portions; the first fixing seat is detachably disposed on any of the first mounting portions and the second fixing seat is detachably disposed on any of the second mounting portions.

[0020] A first mounting plate is provided with multiple spaced-apart first mounting portions and multiple spaced-apart second mounting portions. A first mounting base for mounting the first probe body is detachably mounted on any of the first mounting portions, and a second mounting base for mounting the first suction component is detachably mounted on any of the second mounting portions. Thus, by removing and adjusting the mounting positions of the first and second mounting bases, the positions of the first probe body and the first suction component can be changed, thereby enabling the formation and capacity testing of batteries of different models and specifications.

[0021] Secondly, this application also discloses a reaction and dissolution apparatus, comprising:

[0022] A battery positioning mechanism, the battery positioning mechanism including a shelf plate having a positioning groove for accommodating and positioning a battery to be tested; and a first formation and capacity testing mechanism detachably connected to the battery positioning mechanism so as to test the battery to be tested; the first formation and capacity testing mechanism is any of the above-mentioned formation and capacity testing mechanisms.

[0023] The formation and capacity testing device can be equipped with the aforementioned formation and capacity testing mechanism to adapt to the processing requirements of other types of batteries. This allows the device to be compatible with the processing needs of different types of batteries by switching between existing formation and capacity testing mechanisms and the one provided in this application. Furthermore, by providing positioning slots on the layer plate, the battery to be tested can be placed in the positioning slots for positioning, thereby improving the alignment accuracy of the probe assembly and the terminals / filling holes of the battery to be tested.

[0024] In one possible implementation, the battery positioning mechanism further includes a support frame, and the layer plates include multiple layers, which are sequentially spaced apart on the support frame along the thickness direction of the layer plates. The battery positioning mechanism further includes a clamping member and an elastic reset member. The clamping member is movably disposed on the layer plate and is disposed opposite to the bottom surface of the positioning groove. The clamping member is used to clamp and fix the battery to be tested. The elastic reset member is disposed on the layer plate and the clamping member. One end of the elastic reset member abuts against the layer plate, and the other end of the elastic reset member abuts against the clamping member. The elastic reset member is used to cooperate with the layer plate to clamp and fix the battery to be tested.

[0025] With this setup, after the battery under test is placed in the positioning slot, the elastic reset component and the holding component can be used in conjunction with the shelf to hold and fix the battery under test, thereby enhancing the fixing effect and preventing the battery under test from shifting in subsequent processes.

[0026] Thirdly, this application also discloses a formation and capacity testing system, including a transport device, a robotic arm, and a plurality of the above-mentioned formation and capacity testing devices; the robotic arm is disposed on the transport device, the transport device is movable relative to the plurality of formation and capacity testing devices, the transport device is used to carry batteries, and the robotic arm is used to pick up the batteries and place them on the battery positioning mechanism of the formation and capacity testing devices, or pick up the batteries on the battery positioning mechanism of the formation and capacity testing devices and place them in the transport device.

[0027] Compared with the prior art, this application has at least the following beneficial effects:

[0028] The formation and capacity testing mechanism disclosed in this application can be switched to the existing formation and capacity testing mechanism when the original equipment cannot meet the testing requirements of batteries with horizontally square extension of the terminal post and / or liquid injection port. This allows the original formation and capacity testing mechanism to be switched to the one provided in this application without changing the direction of the force of the original equipment. The first probe body is moved along a second direction intersecting the original direction of the force through the transmission component, so as to adapt to the formation and capacity testing requirements of different types of batteries. This allows the formation and capacity testing equipment and system to adapt to the formation and capacity testing requirements of various steel-cased batteries by switching between the existing formation and capacity testing mechanism and the one provided in this application. In this way, the device, equipment and system equipped with this formation and capacity testing mechanism have good versatility. Attached Figure Description

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] In this application, the terms "upper," "inner," "outer," "middle," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0044] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0045] Furthermore, the terms "provided with" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0046] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0047] Currently, battery formation and capacity testing equipment can only process one type of battery. This requires manufacturers to set up different formation and capacity testing equipment according to different target products, which directly leads to increased equipment footprint and high equipment costs.

[0048] In related technologies, by making the probe assembly on the formation and capacity testing equipment movable, the position of the probe assembly can be adjusted to meet the testing requirements of batteries of different sizes when it is necessary to test them.

[0049] However, the inventors discovered through research that in the above scheme, since the moving direction of the probe assembly does not change and the relative positions between the different probes of the probe assembly do not change, the formation and capacity testing device can still only be used to test specific types of batteries. The distribution of the terminals and the distribution and orientation of the liquid injection ports of these batteries must be consistent; otherwise, the formation and capacity testing device cannot be used.

[0050] To address the aforementioned technical problems, this application discloses a formation and capacity testing mechanism. This mechanism can change the direction of movement of the probe body through a transmission component without altering the direction of the force applied by the original equipment, thereby adapting to the formation and capacity testing requirements of different types of batteries. As a result, the formation and capacity testing equipment and system can adapt to the formation and capacity testing requirements of various battery models by replacing the formation and capacity testing mechanism, exhibiting good versatility.

[0051] Please refer to the following: Figures 1 to 3 ,in, Figure 1 This is a three-dimensional structural diagram of the decomposition and dissolution mechanism according to an embodiment of this application. Figure 2 yes Figure 1 Enlarged diagram of region A in the middle. Figure 3 yes Figure 1 The rear view of the decomposition and capacity mechanism shown.

[0052] The separation and dispensing mechanism 100 includes a first base 110, a first pressure-bearing structure 120, a probe assembly 130, and a transmission component 140.

[0053] In some embodiments, the first pressure-bearing structure 120 is movably disposed on the first base 110 along a first direction P1. The first direction P1 can be a vertical direction (i.e., the height direction of the first base) or a horizontal direction. In this embodiment, the first direction P1 is taken as the height direction for illustration.

[0054] The probe assembly 130 includes a first mounting plate 131 and a first probe body 132. The first mounting plate 131 is movably disposed on the first base 110 along a second direction P2, and the first probe body 132 is disposed on the first mounting plate 131 and extends along the second direction P2. Thus, when the first mounting plate 131 moves along the second direction P2, the first mounting plate 131 can drive the first probe body 132 to move along the second direction P2.

[0055] It should be noted that the second direction P2 intersects the first direction P1. In some embodiments, the second direction P2 may be perpendicular to the first direction P1, that is, the second direction P2 is horizontal. In this embodiment, the second direction P2 being horizontal is used as an example for explanation, but it is not limited thereto.

[0056] In some embodiments, the transmission member 140 has a first end 141 and a second end 142 opposite to each other, the first end 141 being movably connected to the first pressure-bearing structure 120, and the second end 142 being movably connected to the first mounting plate 131.

[0057] Understandably, when the first pressure-bearing structure 120 moves along the first direction P1 under the action of an external force, the first pressure-bearing structure 120 drives the first end 141 of the transmission member 140 to move, and the second end 142 of the transmission member 140 transmits the movement of the first pressure-bearing structure 120 to the first mounting plate 131. Since the first end 141 and the second end 142 are respectively movably connected to the first pressure-bearing structure 120 and the first mounting plate 131, the movement of the first pressure-bearing structure 120 along the first direction P1 is converted into movement along the second direction P2 after being transmitted to the first mounting plate 131 by the transmission member 140. This causes the first probe body 132 to move along the second direction P2 under the drive of the first mounting plate 131 and to contact or separate from the battery under test. For example, the first probe body 132 contacts the terminal of the battery under test to achieve electrical connection.

[0058] Because the formation and capacity testing equipment in related technologies typically applies force to the formation and capacity testing mechanism in a first direction P1, causing the mechanism to move along the first direction P1 to contact or separate from the battery under test, the existing formation and capacity testing equipment and systems are not suitable when it is necessary to test batteries whose terminals and / or filling ports extend along a second direction P2 that intersects with the first direction P1. Other formation and capacity testing equipment and systems are required for this purpose.

[0059] Thus, when the formation and capacity testing mechanism of this application is applied to a formation and capacity testing device, and when it is necessary to test a battery whose terminal extension direction is the second direction P2, it is not necessary to use other dedicated formation and capacity testing equipment. Only the original formation and capacity testing mechanism on the existing equipment needs to be replaced with the formation and capacity testing mechanism 100 provided in this application to meet the testing requirements. This allows the original formation and capacity testing equipment to meet the testing needs of different types of batteries by switching between existing formation and capacity testing mechanisms and the formation and capacity testing mechanism provided in this application, thereby giving the formation and capacity testing equipment and system good versatility. It is evident that using the formation and capacity testing mechanism of this application eliminates the need for dedicated formation and capacity testing equipment and systems for different types of batteries, reducing the types of equipment required in the production process and thus reducing equipment costs.

[0060] Here, the different types of batteries refer to batteries whose terminals and / or filling ports extend in different directions. For example, when some types of batteries are fixed to a formation and capacity testing device, at least one of the battery terminals and filling ports extends upward along a first direction P1, and when other types of batteries are fixed to a formation and capacity testing device, at least one of the battery terminals and filling ports extends horizontally along a second direction P2.

[0061] In some embodiments, the first base 110 may be generally an elongated block. The first base 110 is provided with a first slide rail 150 extending along a first direction P1, and the first pressure-bearing structure 120 is provided with a first slider 121 that cooperates with the first slide rail 150. The first slider 121 is slidable on the first slide rail 150. Through the cooperation of the first slide rail 150 and the first slider 121, the first pressure-bearing structure 120 can move accurately along the first direction P1. It is understood that, as in other embodiments, in order to guide the sliding of the first pressure-bearing structure 120, for example, rollers may be provided on the first base 110, and for example, slide rails or grooves may be provided on the first pressure-bearing structure 120.

[0062] In some embodiments, the first base 110 is provided with a second slide rail 160 extending along a second direction P2, and the first mounting plate 131 is provided with a second slider 131a that cooperates with the second slide rail 160. The second slider 131a is slidable on the second slide rail 160. The cooperation of the second slide rail 160 and the second slider 131a allows the first mounting plate 131 to move along the second direction P2. It is understood that in other embodiments, a guide rod and a slider / ring can also be used. For example, a guide rod can be provided on the first base 110, and a slider / ring that passes through the guide rod and is slidable relative to the guide rod can be provided on the first mounting plate 131.

[0063] In some embodiments, a first reset member 170 is provided between the first base 110 and the first pressure-bearing structure 120. The first reset member 170 has two opposing ends, one end connected to the first base 110 and the other end connected to the first pressure-bearing structure 120. When the first pressure-bearing structure 120 is moved relative to the first base 110 along a first direction P1 under the action of an external force for testing, the first reset member 170 deforms and stores energy. When the test is completed and the external force acting on the first pressure-bearing structure 120 is removed, the first reset member 170 releases the stored energy and drives the first pressure-bearing structure 120 to reset, moving the first pressure-bearing structure 120 to the position relative to the first base 110 before being subjected to the external force.

[0064] Optionally, the first reset member 170 can be an elastic structure such as a spring or a sheet. When the first pressure-bearing structure 120 moves under the action of an external force, the first reset member 170 is compressed and stores elastic potential energy. When the external force acting on the first pressure-bearing structure 120 is removed, the first reset member 170 releases its elastic potential energy and drives the pressure-bearing structure to reset through its own elastic force.

[0065] In some embodiments, the first pressure-bearing structure 120 includes a second mounting plate 122 and a pressure-bearing member 123. The second mounting plate 122 is movably disposed on the first base 110 along a first direction P1, and a first end is movably connected to the second mounting plate 122. The pressure-bearing member 123 is disposed on the second mounting plate 122. Under the action of an external force, the pressure-bearing member 123 drives the second mounting plate 122 to move along the first direction P1, causing the second mounting plate 122 to push the first mounting plate 131 to move along the second direction P2 via the transmission member 140. In this way, the size of the first pressure-bearing structure 120 in the first direction P1 can be increased, the stroke between the structure applying external force to the first pressure-bearing structure 120 and the first pressure-bearing structure 120 can be reduced, and the testing efficiency can be improved. It is understood that the first slider 121 is disposed on the second mounting plate 122, and the first reset member 170 is disposed between the second mounting plate 122 and the first base 110.

[0066] In some embodiments, the pressure-bearing member 123 may be a roller, which is rotatably disposed on the second mounting plate 122, and the roller and the transmission member 140 are spaced apart along the first direction P1. By setting the pressure-bearing member 123 as a roller, when there is a displacement at an angle to the first direction P1 between the structure applying external force to the roller and the roller, the roller can rotate under the action of the structure, avoiding the second mounting plate 122 from swaying due to the aforementioned displacement, and ensuring the stability of the position of the first probe body 132. For example, when the pressing structure of the formulation and dispensing device presses down on the pressure-bearing member 123 along the height direction, if there is a horizontal displacement between the pressing structure and the pressure-bearing member 123, the roller can rotate to counteract the effect of the horizontal displacement on the second mounting plate 122.

[0067] Of course, in some other embodiments, the pressure-bearing member 123 can also be an elastic member, such as rubber, silicone, spring, etc. Setting the pressure-bearing member 123 as an elastic member can not only reduce the impact of the horizontal displacement of the pressing structure of the forming and dispensing device on the second mounting plate 122 through elastic deformation, but also provide a certain buffering capacity to prevent the action of the pressing structure or excessive pressure from causing damage to the forming and dispensing mechanism 100.

[0068] In some embodiments, the transmission member 140 may be a connecting rod, with its first end rotatably connected to the second mounting plate 122 and its second end rotatably connected to the first mounting plate 131. Thus, when the second mounting plate 122 moves downward along the first direction P, it abuts against the first end of the connecting rod, causing the first end of the connecting rod to rotate relative to the second mounting plate 122, thereby causing the second end to rotate upward relative to the first end. Since the second end is rotatably connected to the first mounting plate 131, the second end pushes the first mounting plate 131 to move on the second slide rail 160.

[0069] As can be seen, the transmission component adopts a connecting rod, which can realize the force transmission by rotating the two ends respectively. The structure is simple and the force transmission is more direct and effective, which helps to simplify the structural design of the separation and dispensing mechanism.

[0070] In some embodiments, the first base 110 includes a first seat body 111 and a second seat body 112. The first seat body 111 is disposed on the second seat body 112 along a first direction P1. A first pressure-bearing structure 120 (specifically a second mounting plate and a pressure-bearing member) is movably disposed on the first seat body 111 along the first direction P1, thereby being able to move closer to or further away from the second seat body 112 along the first direction P1. It is understood that a first slide rail 150 is disposed on the first seat body 111, and a first reset member 170 is disposed between the second mounting plate 122 and the first seat body 111.

[0071] In some embodiments, the second base 112 extends along the second direction P2 and protrudes relative to the first base 111. That is, in a cross-section parallel to the plane formed by the intersection of the first direction P1 and the second direction P2, the first base is configured in an L-shape. It can be understood that since the first mounting plate 131 is movably disposed on the first base 110 along the second direction P2, the second slide rail 160 is disposed on the second base 112.

[0072] In some embodiments, the second base 112 is provided with a connection hole 112a, which is used to cooperate in positioning and connecting other structures of the formation and capacity testing equipment, so that the first probe body 132 is aligned with the detection position of the battery to be tested mounted on the formation and capacity testing equipment.

[0073] In some embodiments, the first mounting plate 131 includes a first sub-plate 131b and a second sub-plate 131c disposed on the first sub-plate 131b. The first sub-plate 131b is movably disposed on the second base 112 along a second direction P2, and the first probe body 132 is disposed on the second sub-plate 131c. The second base 112 is provided with a first clearance groove 112b along a first direction P1, and the second sub-plate 131c is at least partially located in the first clearance groove 112b. This configuration improves the compactness of the internal structure of the fractionation filling mechanism 100, which is beneficial for achieving a miniaturized design of the fractionation filling mechanism 100.

[0074] It is understandable that the second slider 131a is disposed on the first sub-plate 131b, thereby cooperating with the second slide rail 160 on the second seat 112.

[0075] In some embodiments, the first sub-plate 131b and the second sub-plate 131c are sequentially arranged along a first direction P1. For example, the first sub-plate 131b is located above the second sub-plate 131c in the height direction, and the dimension of the first sub-plate in the third direction P3 (i.e., the length direction of the first base 110) is larger than the dimension of the second sub-plate in the third direction P3, so that the first mounting plate 131 is formed into an inverted convex shape. Of course, as in other embodiments, the dimensions of the first sub-plate 131b and the second sub-plate 131c in the third direction P3 may also be the same.

[0076] In some embodiments, the first seat 111 is provided with a second clearance groove 111a along the second direction P2. The second clearance groove 111a communicates with the first clearance groove 112b along the first direction P1. For example, the first seat 111 can be an inverted U-shaped structure, and there are two second seats 112. The two second seats 112 are connected one-to-one to the two ends of the inverted U-shaped structure and extend along the second direction P2. In this case, it can be understood that there are two first slide rails 150 and two slide rails 160. The two first slide rails 150 are respectively disposed at the two ends of the inverted U-shaped structure, and the two second slide rails 160 are respectively disposed on the two second seats 112. Correspondingly, there are two first sliders 121 and two sliders 131a. The two first sliders 121 are respectively disposed one-to-one with the two first slide rails 150, and the two second sliders 131a are respectively disposed one-to-one with the two second slide rails 160.

[0077] In some embodiments, at least a portion of the first subplate 131b is located in the second clearance groove 111a in the second direction P2, so as to move in the second clearance groove 111a along the first direction P1. This improves the compactness of the internal structure of the fractionation filling mechanism 100, which is beneficial for achieving a miniaturized design of the fractionation filling mechanism 100.

[0078] Please see also Figure 4 , Figure 4 This is a schematic diagram of the structure of a first probe body in an embodiment of this application.

[0079] In some embodiments, the probe assembly 130 further includes a first mounting base 133, a first probe body 132 disposed on the first mounting base 133, and a first mounting plate 131 having a plurality of spaced-apart first mounting portions (not shown). The first mounting base 133 is detachably disposed on any one of the first mounting portions. With this configuration, when the model or specification of the battery to be tested is changed, the position of the first probe body 132 can be changed by adjusting the position of the first mounting base 133, thereby adapting to the testing requirements of different battery models / specifications.

[0080] It is understandable that the first fixing seat 133 is disposed on the second sub-plate 131c, and the first fixing seat 133 and the second sub-plate 131c can be detachably connected by means of screwing, snap-fitting, plugging, etc. This application does not make specific limitations in this regard.

[0081] In some embodiments, the probe assembly 130 further includes a first suction component 134, which is disposed on the first mounting plate 131. The first suction component 134 is used to vent air from the battery under test. Optionally, the first suction component 134 can be a nozzle, a pipette, or the like. Thus, the first suction component 134 can be used to vent air from the battery under test, that is, to remove air from the battery, preventing air from remaining inside the battery, thereby improving battery performance and reducing the probability of internal battery fire. It is understood that the first suction component 134 is disposed on the second sub-board 131c.

[0082] In some embodiments, the probe assembly 130 further includes a second mounting base 135, a first suction component 134 is disposed on the second mounting base 135, and a plurality of spaced-apart second mounting portions (not shown) are disposed on the second sub-board 131c, the second mounting portions being spaced apart from the first mounting portions, and the second mounting base 135 being detachably disposed on any one of the second mounting portions. With this configuration, when the model / specification of the battery to be tested is changed, the position of the second mounting base 135 can be adjusted to change the position of the first suction component 134, thereby adapting to the testing requirements of different models / specifications of batteries.

[0083] Optionally, the second fixing seat 135 and the second sub-board 131c can be detachably connected by means of screwing, snap-fitting, plugging, etc. This application does not make specific limitations in this regard.

[0084] In some embodiments, the first mounting bracket 133 and the second mounting bracket 135 can be detachably connected to the second sub-board 131c via the same structure. This arrangement also allows for adaptation to the testing requirements of the battery under test by swapping the relative positions of the first mounting bracket 133 and the second mounting bracket 135, based on the actual design of the battery.

[0085] See Figures 5 to 8 , Figure 5 This is a schematic diagram of the structure of the chemical separation and dissolution apparatus according to an embodiment of this application. Figure 6 for Figure 5 The schematic diagram shown is of the battery positioning mechanism of the formation and capacity device. Figure 7 for Figure 5 The diagram shows a front view of the positioning groove component of the chemical composition and dispensing device. Figure 8 for Figure 7 The diagram shows a bottom view of the positioning groove component.

[0086] This application also discloses a formation and capacity testing device 200, which includes a battery positioning mechanism 210 and a first formation and capacity testing mechanism (not shown).

[0087] The battery positioning mechanism 210 is used to position the battery to be tested, and the first formation and capacity-setting mechanism is used to detachably connect to the battery positioning mechanism 210 so that the first formation and capacity-setting mechanism can test the battery to be tested.

[0088] In some embodiments, the formation and capacity testing device 200 further includes a second formation and capacity testing mechanism 220, which is detachably connected to the battery positioning mechanism 210 for testing its corresponding battery under test. It is understood that both the first and second formation and capacity testing mechanisms 220 are designed to test different types of batteries under test; for example, the first formation and capacity testing mechanism is used to test a first type of battery, and the second formation and capacity testing mechanism 220 is used to test a second type of battery. The battery type can be distinguished according to the orientation of the battery terminals and / or the electrolyte filling port.

[0089] In some embodiments, the formation and capacity testing device 200 has a first test state and a second test state. When the formation and capacity testing device 200 is in the first test state, a first formation and capacity testing mechanism is connected to the battery positioning mechanism 210 so that the first formation and capacity testing mechanism tests a first type of battery. When the formation and capacity testing device 200 is in the second test state, a second formation and capacity testing mechanism 220 is connected to the battery positioning mechanism 210 so that the second formation and capacity testing mechanism 220 tests a second type of battery. The extending directions of the liquid injection holes and / or terminals of the first type of battery intersect with the extending directions of the liquid injection holes and / or terminals of the second type of battery.

[0090] In some embodiments, the first formation and compatibility mechanism may be the formation and compatibility mechanism 100 of any of the above embodiments.

[0091] For example, when the first type of battery is fixed to the battery positioning mechanism 210, the extension direction of the terminal post and / or the liquid filling hole of the first type of battery can be horizontal (i.e., the second direction P2 mentioned above). When the second type of battery is fixed to the battery positioning mechanism 210, the extension direction of the terminal post and / or the liquid filling hole of the second type of battery can be upward along the height direction (i.e., the first direction P1 mentioned above).

[0092] For example, consider a steel-cased battery of type I with terminals and filling holes extending horizontally, and a steel-cased battery of type II with terminals and filling holes extending upwards in the height direction.

[0093] When testing the first type of battery is required, the first formation and capacity testing mechanism can be assembled onto the formation and capacity testing device, and the first type of battery to be tested can be fixed onto the battery positioning mechanism 210. When the pressure-bearing component of the first formation and capacity testing mechanism is subjected to an external force acting downward in the height direction, the second mounting plate 122 moves downward in the height direction, and through the transmission component 140, the first sub-plate 131b moves horizontally, so as to drive the first probe body 132 to move synchronously and in the same direction until it contacts the first type of battery to be tested for testing. After the test is completed, the external force acting on the pressure-bearing component 123 is removed, and the pressure-bearing component 123 drives the second mounting plate 122 to reset. The second mounting plate 122 drives the first sub-plate 131b to move synchronously with the first probe body 132 and move away from the first type of battery that has been tested through the transmission component 140.

[0094] Understandably, when the first probe body 132 contacts the first type of battery, the first probe body 132 is electrically connected to the terminal of the first type of battery to achieve detection. When the second sub-board 131c is also provided with a first suction component 134, the first suction component 134 is connected to the liquid injection port of the first type of battery, and the first suction component 134 is connected to the inside of the casing of the first type of battery through the liquid injection port, so as to perform air extraction.

[0095] When testing the second type of battery, the first formation and capacity testing mechanism originally mounted on the formation and capacity testing device 200 can be removed and replaced with the second formation and capacity testing mechanism 220, thereby enabling the testing of the second type of battery using the second formation and capacity testing mechanism 220. After the second type of battery is fixed on the battery positioning mechanism 210, the second formation and capacity testing mechanism 220 is subjected to a downward force along the height direction. The third mounting plate 222 drives the second probe body 224 to move downward synchronously, so that the second probe body 224 contacts the second type of battery, realizing the electrical connection between the two for testing. Furthermore, when the third mounting plate 222 is provided with a second suction component 225, the second suction component 225 connects to the inside of the battery casing through the liquid injection port on the second type of battery to perform air extraction.

[0096] When the first type of battery needs to be tested again, the second formation and capacity testing mechanism 220 can be replaced with the first formation and capacity testing mechanism. It is evident that when different types of batteries need to be tested, adaptation can be achieved by replacing the formation and capacity testing mechanism on the formation and capacity testing device 200, thereby reducing production costs.

[0097] In some embodiments, the battery positioning mechanism 210 includes a shelf 211 with a positioning groove 211a for accommodating and positioning a first type of battery or a second type of battery. It is understood that both the first and second formation and capacity-setting mechanisms 220 are detachably connected to the shelf 211.

[0098] In some embodiments, the shelf 211 can be heated to heat the battery under test placed on the shelf 211 for thermoforming. For example, the shelf 211 is made of metal, and heating wires (not shown) can be provided on the shelf 211. When the heating wires are energized, they use electrical energy to generate heat, causing the temperature of the shelf 211 to rise. To improve heating efficiency and ensure uniform temperature distribution, the heating wires can be arranged in a serpentine pattern on the shelf 211.

[0099] In some embodiments, both the first and second fractionation filling mechanisms 220 can be detachably fixed to the shelf 211 by insertion. For example, both the first and second fractionation filling mechanisms 220 can be provided with the aforementioned connecting hole 112a, and the shelf 211 is provided with a pin (not shown) that mates with the connecting hole 112a. Alternatively, both the first and second fractionation filling mechanisms 220 can be provided with a pin, and the shelf 211 is provided with the aforementioned connecting hole 112a that mates with the pin. In this way, the cooperation of the pin and the connecting hole 112a enables efficient and rapid disassembly and replacement, and also ensures the positional accuracy of the first and second fractionation filling mechanisms 220 after they are connected to the shelf 211.

[0100] In some embodiments, the positioning groove 211a is a contoured groove. For example, if the battery being tested is a square steel-cased battery, the contoured groove can be set as a square groove. If the battery being tested is a cylindrical battery, the square groove can be set as a circular groove.

[0101] Optionally, several detachable protrusions can be provided in the positioning groove 211a. By installing or removing at least one of the protrusions, the size and shape of the positioning groove 211a can be changed to match a variety of different batteries, thereby adapting to the testing requirements of different batteries.

[0102] In some embodiments, the battery positioning mechanism 210 further includes a support frame 212, and multiple shelves 211 may be provided, with the multiple shelves 211 spaced apart on the support frame 212 along their own thickness direction.

[0103] Under normal circumstances, the formation and capacity testing device 200 will not simultaneously include both the first and second formation and capacity testing mechanisms 220. However, in some cases, both mechanisms can be simultaneously installed on the device. For example, the area occupied by multiple layers 211 can be divided into adjacent first and second regions along the thickness direction of the layers 211. In the first region, multiple first formation and capacity testing mechanisms are sequentially spaced along the thickness direction of the layers 211 and connected to each layer 211 in a one-to-one correspondence. In the second region, multiple second formation and capacity testing mechanisms 220 are sequentially spaced along the thickness direction of the layers 211 and connected to each layer 211 in a one-to-one correspondence. This arrangement allows for simultaneous testing of two types of batteries within a single production batch.

[0104] In some embodiments, multiple layers 211 are movably disposed on the support frame 212 along their own thickness direction. With this configuration, when the battery to be tested is placed in the positioning groove 211a, the battery to be tested placed in the positioning groove 211a can be squeezed and fixed by driving the multiple layers 211 to move closer to each other.

[0105] In some embodiments, the support frame 212 may include a plurality of parallel support rods, and each shelf 211 is provided with a plurality of spaced through holes 211b. Each shelf 211 is able to slide along the support rods by having the support rods pass through the through holes 211b in a corresponding manner.

[0106] In some embodiments, the edge of the layer plate 211 forming the through hole 211b may be provided with some protrusions and / or grooves, and the surface of the support rod may be provided with some protrusions and / or grooves extending axially along the support rod, such that the protrusions or grooves and / or grooves at the edge of the through hole cooperate with the protrusions and / or grooves on the surface of the support rod (e.g., the protrusions at the edge of the layer plate 211 forming the through hole 211b are embedded in the grooves on the surface of the support rod, and vice versa), so that the layer plate 211 can only move axially relative to the support rod, but cannot rotate or move radially relative to the support rod. In this way, the stability of the layer plate 211 on the support rod can be ensured, thereby ensuring the stability of the position of the battery to be tested disposed on the layer plate 211.

[0107] In other embodiments, an elastic component (not shown), such as rubber or silicone, can be provided at the edge of the through hole formed by the layer plate 211. When the support rod passes through the through hole 211b of the layer plate 211, the surface of the support rod fits tightly against the elastic component. In this way, the elastic force of the elastic component and the friction between the surface of the support rod and the elastic component can be used to fix the position of the layer plate 211, thereby ensuring the stability of the position of the battery to be tested placed on the layer plate 211.

[0108] In some embodiments, at least one through hole 211b on the layer 211 can be configured as a non-circular through hole, such as an elliptical hole, an oval hole, a polygonal hole, etc. Adaptively, the shape and size of the radial cross-section of at least one support rod matches the through hole.

[0109] In some embodiments, the battery positioning mechanism 210 further includes a clamping member 213 and an elastic reset member (not shown). The clamping member 213 is movably disposed on the shelf 211 and opposite to the bottom surface of the positioning groove 211a. The elastic reset member is disposed between the shelf 211 and the clamping member 213. The elastic reset member has two opposing ends, one end abutting against the shelf 211 and the other end abutting against the clamping member 213. By moving the clamping member 213, the positioning groove 211a can be exposed. The clamping member 213 simultaneously compresses the elastic reset member, facilitating the placement of the battery to be tested into the positioning groove 211a. After the battery to be tested is placed, the clamping member 213 is released, and the elastic reset member uses its elastic force to reset the clamping member 213. The clamping member 213 and the shelf 211 cooperate to clamp and fix the battery to be tested. Optionally, the elastic reset member can be a spring, a sheet spring, etc.

[0110] In some embodiments, the battery positioning mechanism 210 further includes a paddle 214, which is fixedly connected to the clamping member 213. By moving the paddle 214, the clamping member 213 can be driven to move relative to the shelf 211 and compress the elastic member.

[0111] It is understandable that each shelf 211 can be equipped with corresponding clamping elements 213, elastic elements, and paddles 214.

[0112] See you again Figure 7 and Figure 8 In some embodiments, the battery positioning mechanism 210 includes a positioning component 215, which is fixed to the shelf plate 211 by means of snap-fit, hook-fit, plug-in, or screw-fit. A positioning groove 211a is provided on the positioning component 215. This arrangement allows different positioning components 215 to have positioning grooves 211a of different shapes and / or sizes. The shape of the contoured groove on the shelf plate 211 can be changed by replacing the positioning component 215 to adapt to the testing requirements of different batteries to be tested.

[0113] In some embodiments, the battery positioning mechanism 210 further includes a connecting plate 216 and a buffer 217. The connecting plate 216 is connected to the positioning component 215 and is located on the side of the shelf 211 opposite to the clamping component 213. The buffer 217 is disposed on the side of the connecting plate 216 opposite to the clamping component 213. When the battery to be tested is placed and the shelf 211 is driven to press against each other to fix the battery to be tested, the buffer 217 can buffer between adjacent shelf 211 to prevent the shelf 211 and / or the battery to be tested from being crushed.

[0114] Please see also Figure 9 and Figure 10 , Figure 9 This is a front view of the second chemical composition and capacity mechanism of the chemical composition and capacity apparatus according to an embodiment of this application. Figure 10 for Figure 9 A side view of the second chemical separation and capacity mechanism is shown.

[0115] In some embodiments, the second decomposition and dispensing mechanism 220 includes a second base 221, a third mounting plate 222, a second pressure-bearing structure 223, and a second probe body 224.

[0116] The third mounting plate 222 is movably disposed on the second base 221 along the first direction P1. The second pressure-bearing structure 223 and the second probe body 224 are both disposed on the third mounting plate 222. The second pressure-bearing structure 223 and the second probe body 224 are spaced apart along the first direction P1, and the second probe body 224 extends along the first direction P1. The second pressure-bearing structure 223 is used to move along the first direction P1 under the action of external force, and drives the second probe body 224 to move along the first direction P1 through the third mounting plate 222 to contact or separate from the battery under test.

[0117] In some embodiments, the second decomposition and dispensing mechanism 220 further includes a third slide rail 230, which is disposed on a third mounting plate 222. The third mounting plate 222 is provided with a third slider 222a, which cooperates with the third slide rail 230 and is capable of sliding along the third slide rail 230. The third mounting plate 222 moves in a first direction P1 through the cooperation of the third slide rail 230 and the third slider 222a.

[0118] Understandably, the second pressure-bearing structure 223 can be set with reference to the first pressure-bearing structure 120, and the second probe body 224 can be set with reference to the first probe body 132. This will not be elaborated here.

[0119] In some embodiments, the second formation and capacity-setting mechanism 220 further includes a second suction component 225, which is disposed on the third mounting plate 222 and is used to vent the battery under test. It is understood that the second suction component 225 can be configured with reference to the first suction component 134, and the connection between the second suction component 225 and the third mounting plate 222 can also be configured with reference to the connection between the first suction component 234 and the first 131c. For example, the second suction component 225 can be detachably mounted on the mounting portion of the third mounting plate 222 using a detachable fixing seat, and the third mounting plate 222 can have multiple mounting portions.

[0120] In some embodiments, a second reset member 240 is provided between the second base 221 and the third mounting plate 222. The second reset member 240 has two opposing ends, one end of which is connected to the second base 221 and the other end of which is connected to the third mounting plate 222. When the third mounting plate 222 is driven by an external force to move along the first direction P1, the second reset member 240 undergoes elastic deformation. The second reset member 240 stores elastic potential energy. When the external force acting on the second pressure-bearing structure 223 is removed, the second reset member 240 releases the elastic potential energy and applies an elastic force to the third mounting plate 222 to reset the third mounting plate 222.

[0121] Understandably, since the formation and capacity testing mechanism on the formation and capacity testing device 200 can be switched between the first formation and capacity testing mechanism and the second formation and capacity testing mechanism 220, the formation and capacity testing device 200 can adapt to the formation and capacity testing requirements of different types of batteries, improve the versatility of the formation and capacity testing device 200, and reduce production costs.

[0122] Please see also Figure 11 , Figure 11 This is a schematic diagram of the structure of a chemical composition and capacity preparation device according to an embodiment of this application.

[0123] This application also discloses a chemical composition and formulation apparatus 300, which includes the chemical composition and formulation device 200 of any of the above embodiments.

[0124] In some embodiments, the formation and capacity testing apparatus 300 further includes a housing 310 and a restraint press 320, both of which are disposed within the housing 310. The restraint press 320 is used to apply pressure to multiple layers 211 at both ends of the formation and capacity testing apparatus 200 in the thickness direction of the layers 211, causing the multiple layers 211 to press against each other, thereby fixing and pressurizing the battery to be tested.

[0125] In some embodiments, the formation and capacity-deploying apparatus 300 may include a plurality of formation and capacity-deploying devices 200, each of which is provided with a corresponding restraint press 320.

[0126] It is understandable that, since the formation and capacity testing equipment 300 includes the aforementioned formation and capacity testing device 200, by replacing the formation and capacity testing mechanism of the formation and capacity testing device 200, for example, by switching between the first formation and capacity testing mechanism and the second formation and capacity testing mechanism 220, the formation and capacity testing equipment 300 can adapt to the formation and capacity testing requirements of different types of batteries, thereby improving the versatility of the formation and capacity testing equipment 300 and reducing production costs.

[0127] In some other embodiments, the plurality of formation and capacity-forming devices 200 in the formation and capacity-forming device 300 are not spaced apart along the height direction, but are spaced apart along the horizontal direction.

[0128] Please see also Figure 12 , Figure 12 This is a schematic diagram of the structure of a formulation and compatibilization system according to an embodiment of this application.

[0129] This application also discloses a formulation and compatibility system 400, which includes a plurality of the above-mentioned formulation and compatibility devices 300, which are arranged at intervals.

[0130] In some embodiments, the formation and capacity testing system 400 further includes a transport device 410 and at least one robotic arm 420. The robotic arm 420 is disposed on the transport device 410, which is used to load batteries to be tested or batteries that have completed testing. The robotic arm 420 is used to pick up batteries from the transport device 410 and place them onto a shelf 211; alternatively, the robotic arm 420 can also remove batteries from the shelf 211 and place them into the transport device 410. The transport device 410 can be a trolley, conveyor belt, etc., and this embodiment does not specifically limit its use.

[0131] In some embodiments, the robotic arm 420 may be a six-axis robotic arm with multiple degrees of freedom, which enables more accurate and flexible picking and placing of batteries.

[0132] In some embodiments, the transport device 410 is movable relative to the formation and testing device 300, so that the transport device 410 can load multiple batteries to be tested that can be carried by the formation and testing device 300 at a time. After loading and unloading is completed at one formation and testing device 300, it moves to another formation and testing device 300 for loading and unloading.

[0133] It is understandable that, since the formation and capacity testing system 400 includes the aforementioned formation and capacity testing equipment 300, and the formation and capacity testing equipment 300 includes the aforementioned formation and capacity testing device 200, by replacing the formation and capacity testing mechanism of the formation and capacity testing device 200, for example, by switching between the first formation and capacity testing mechanism and the second formation and capacity testing mechanism 220, the formation and capacity testing system 400 can adapt to the formation and capacity testing requirements of different types of batteries, thereby improving the versatility of the formation and capacity testing system 400 and reducing production costs.

[0134] The foregoing has provided a detailed description of a formation and capacity-dispensing mechanism, apparatus, and system disclosed in the embodiments of this application. This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the formation and capacity-dispensing mechanism, apparatus, equipment, and system of this application and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
