[0066] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0067] It should be pointed out that the terms "first\second\third" involved in the embodiments of the present application are used to distinguish similar or different objects, and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0068] It should be noted that the terms "including," "having," and any variations thereof in the embodiments and drawings of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to the process, method, product, or apparatus.

[0069] In the actual battery production process, as market demand for battery diversification continues to grow, battery sizes and specifications are becoming increasingly diverse. From small, common 3C product batteries to large energy storage batteries, sizes vary greatly. In order to efficiently produce batteries of different sizes on the same production line, battery production equipment must be converted.

[0070] In existing technology, automated positioning tooling is the mainstream technology for achieving equipment conversions. During conversions, all probe assemblies in each row of the equipment must be adjusted synchronously. From a mechanical engineering perspective, achieving synchronized and precise adjustment of numerous probe assemblies across different rows presents significant challenges in mechanical design. Specifically, each probe assembly is composed of multiple components. According to industry high-precision production standards, the dimensional accuracy of these components must be controlled within extremely tight tolerances. Even dimensional errors down to the micron level can accumulate and amplify during subsequent adjustments, significantly impacting the overall adjustment effect. Furthermore, the installation position accuracy of each component must be strictly controlled. Any slight installation deviation can cause inaccurate coordination between components, violating the expected kinematic and dynamic requirements. This stringent requirement for high precision requires not only advanced precision machining techniques but also complex assembly processes, significantly increasing the complexity of mechanical design. This complex mechanical structure inevitably results in limited flexibility for the equipment to handle the characteristics of different battery models.

[0071] Furthermore, the entire adjustment process involves the coordinated operation of numerous components. Error analysis theory shows that even a small deviation in any particular step will accumulate during subsequent synchronous adjustments, following specific error propagation patterns. Ultimately, after the changeover, the equipment's accuracy struggles to meet high-precision production standards. This is especially true in production scenarios with stringent precision requirements and the need to frequently switch between column counts and multiple battery models. Adjustments can only be made at each storage location, resulting in very low changeover efficiency.

[0072] The embodiments of the present application disclose a control method, control system, and chemical fractionation and containment equipment. Not only does the unlocking mechanism integrated in the chemical fractionation and containment equipment enable the chemical fractionation and containment equipment to have a changeover function, but also, due to its related control logic and calculation method, the chemical fractionation and containment equipment can adjust the number of changeover groups and the size of the changeover as needed, thereby improving the flexibility of the chemical fractionation and containment equipment. In addition, due to the changeover method using two unlocking mechanisms, the efficiency of the changeover is improved. The following are detailed descriptions:

[0073] The present application discloses a control method for a battery cell splitting device, which is applied to a control system. The control system is used to control the battery cell splitting device to adjust the position of at least one set of fixed components to adapt the fixed components to the position of a target battery. Each set of fixed components includes at least two components. The battery cell splitting device includes a moving mechanism and at least two sets of unlocking mechanisms, with the two unlocking mechanisms in each set of unlocking mechanisms positioned in corresponding positions. The following description of the present application embodiment primarily uses two sets of unlocking mechanisms as an example.

[0074] See also Figure 1 , Figure 1A schematic diagram of an implementation environment of a chemical fractionation device provided in an embodiment of the present application includes at least two groups of unlocking mechanisms 202 in the chemical fractionation device 20, multiple groups of fixing components 30, and multiple target batteries 41, wherein the positions of each group of unlocking mechanisms correspond to each other, and at least two groups of unlocking mechanisms 202 include a first unlocking mechanism 22 and a second unlocking mechanism 23.

[0075] In the method, the control system determines the starting position information of each group of fixed components; and also determines the target moving distance of the reference group fixed components based on the preset local position information of at least one target component in the target battery 41, the starting position information of each group of fixed components, the preset anti-collision compensation value and the preset center line position. Then, based on the target moving distance of the reference group fixed components and the preset installation position information of the target battery 41, the target moving distance of the remaining groups of fixed components in at least one group of fixed components except the reference group fixed components is determined; wherein, at least one target component corresponds one-to-one to at least one group of fixed components; finally, based on the target moving distance of each group of fixed components in at least one group of fixed components, the at least two groups of unlocking mechanisms 202 are controlled to move on the moving mechanism to drive at least two components in one group of fixed components to move the corresponding target moving distance, until each group of fixed components moves the corresponding target moving distance.

[0076] To understand the above method flow more clearly, please refer to Figure 2 , Figure 2 A flowchart of a method for controlling a chemical fractionation device provided in an embodiment of the present application includes at least the following steps S101-S103:

[0077] Step S101: determining the starting position information of each group of fixed components;

[0078] Each group of fixed components refers to the starting position information of all groups of fixed components on the cell-splitting device.

[0079] Step S102: determining a target moving distance of the reference group fixed component based on the preset local position information of at least one target component of the target battery 41, the starting position information of the reference group fixed component, the preset anti-collision compensation value, and the preset centerline position;

[0080] The local position information of at least one target component of the target battery refers to the position information of each component after the base column fixed component is replaced. The at least one target component corresponds one-to-one to at least two components of the base group fixed component.

[0081] In a specific embodiment, the at least one target component refers to the left pole, right pole, and liquid filling port of the target battery, and is not specifically limited here. The at least two components of the reference column fixed assembly refer to the left probe assembly, right probe assembly, and negative pressure assembly, and are not specifically limited here. That is, the position of the left pole of the target battery corresponds to the position of the left probe assembly of the reference column fixed assembly after the model is changed, the position of the right pole of the target battery corresponds to the position of the right probe assembly of the reference column fixed assembly after the model is changed, and the position of the liquid filling port of the target battery corresponds to the position of the negative pressure assembly of the reference column fixed assembly.

[0082] The electrode is the metal conductive part of the battery, usually made of materials with good conductivity such as copper or aluminum. The function of the electrode is to connect the positive and negative poles of the battery and to the external circuit. In the chemical composition equipment, the electrode needs to be in contact with the probe assembly to transmit current through the probe so that the battery can be charged and discharged. The probe assembly is a device used to contact the battery's electrode, usually composed of multiple probes. These probes need to be able to accurately contact the positive and negative electrodes of the battery to ensure that the battery's charging and discharging process can proceed normally. The design of the probe assembly needs to consider multiple factors, including the material, elasticity, contact pressure, etc. of the probe to ensure contact stability and avoid poor contact or damage to the battery electrode.

[0083] Step S103: determining target moving distances of the remaining fixed components in at least one group of fixed components except the reference group of fixed components according to the target moving distance of the reference group of fixed components and the preset target battery installation position information;

[0084] The preset anti-collision compensation value is half of the distance between the components with the smallest distance among all components that need to be replaced, which is mainly used to prevent collision problems during the replacement process.

[0085] The preset centerline position is the center of the column of the tray of the chemical fractionation and storage equipment. The specific setting corresponding to it is made according to the type of different chemical fractionation and storage equipment, and no specific limitation is made here.

[0086] In an embodiment, a group of fixed components close to a preset centerline position is used as a reference column fixed component. Often, the reference column fixed component is the fixed component located in the middle of all groups of fixed components that need to be adjusted.

[0087] Step S104: According to the target movement distance of each fixed component in the at least one group of fixed components, controlling the at least two unlocking mechanisms 202 to move on the moving mechanism to respectively drive at least two components in one group of fixed components to move the corresponding target movement distance, until each group of fixed components moves the corresponding target movement distance;

[0088] Among them, one of the at least two unlocking mechanisms 202 located on the left side drives the components located on the left side of the at least two components, and the other of the at least two unlocking mechanisms 202 located on the right side drives the components located on the right side of the at least two components.

[0089] In the above method, the control system calculates the target moving distance of each group of fixed components, and can control at least two groups of unlocking mechanisms 202 on the chemical component sub-device to change the type of each group of fixed components based on the accurately calculated target moving distance of each group of fixed components. Since the unlocking mechanism is integrated on the chemical component sub-device, the change method is simple. Moreover, since the position of each group of fixed components is accurately calculated based on the preset local position information of each target component of at least one target component of the target battery 41, the starting position information of each fixed component in each group of fixed components, the preset anti-collision compensation value, the preset center line position and the preset installation information of the target battery, the change position of each fixed component is accurately calculated, thereby improving the accuracy of the change. Moreover, according to the changeover logic of the present method, the number of columns to be changed can be selected as needed, thereby improving the flexibility of the changeover. In addition, the method uses at least two sets of unlocking mechanisms 202 for changeover, and one set of unlocking mechanisms located on the left side of the at least two sets of unlocking mechanisms 202 drives the components located on the left side of the at least two components, and the other set of unlocking mechanisms located on the right side of the at least two sets of unlocking mechanisms 202 drives the components located on the right side of the at least two components, so that the unlocking mechanism on the left can adapt to the left limit position, and the unlocking mechanism on the right can adapt to the right limit position, which can shorten the changeover stroke. Moreover, the use of two sets of unlocking mechanisms can move two components at the same time, thereby improving the changeover efficiency.

[0090] In some embodiments, please refer to Figure 1 Each unlocking mechanism in each of the at least two groups of unlocking mechanisms 202 includes a sensor 24 and a locking component (not shown in the figure). In step S101, the starting position information of each group of fixed components is determined, which can be: initializing the unlocking mechanism according to the first control instruction so that the unlocking mechanism is positioned at the initial position of the unlocking mechanism; and controlling the sensor 24 to be in a scanning state and controlling the moving mechanism 201 to drive the unlocking mechanism to move at a uniform speed from the initial position of the unlocking mechanism to a preset positive direction, so as to drive the sensor 24 to move; and obtaining the starting position information of each group of fixed components based on the electrical signal obtained when the sensor 24 moves to the locking component during the movement process.

[0091] Optionally, the sensor 24 can be a laser sensor, which is used to transmit a potential signal to the programmable logic controller whenever a locking component appears in the monitoring area of ​​the laser sensor during the movement of the target unlocking mechanism. The programmable controller 12 records the rising edge and falling edge of the potential signal of the laser sensor 24, records N data, and uploads the N data to the control system. The control system defines every two data as 1 group, and uses the absolute value of the subtraction between each group of data to determine the type of each fixed component and the initial position of each fixed component in at least one corresponding group of fixed components.

[0092] In some embodiments, before controlling the chemical composition device to move each set of fixed components to a corresponding target distance in step S104, in order to prevent other fixed components 31 not participating in the change from interfering with the change that requires at least two sets of unlocking mechanisms 202 during the movement, it is necessary to first move the fixed components 31 that do not need to participate in the change to an avoidance position. The preset avoidance position information is information pre-set to the control system. For a clear understanding of the method flow, please refer to Figure 3 , Figure 3 A flowchart of another method for controlling a chemical fractionation device provided in an embodiment of the present application, the flowchart at least includes the following steps S201-S206:

[0093] Step S201: determining the starting position information of each group of fixed components;

[0094] Step S202: determining a target moving distance of the reference group fixed component based on preset local position information of at least one target component in the target battery 41, the starting position information of the reference group fixed component, a preset anti-collision compensation value, and a preset centerline position;

[0095] Step S203: determining target moving distances of the remaining fixed components in at least one group of fixed components except the reference group of fixed components according to the target moving distance of the reference group of fixed components and the preset target battery 41 installation position information;

[0096] Step S204: obtaining target moving distances of other groups of fixed components based on the starting position information of each group of fixed components and the preset avoidance position information;

[0097] Among them, the other groups of fixed components are fixed components that do not participate in the changeover;

[0098] Step S205 : controlling at least two unlocking mechanisms 202 according to the control instruction to drive other fixed components to move the corresponding target moving distances of the other fixed components.

[0099] Step S206: According to the target moving distance of each group of fixed components in at least one group of fixed components, control at least two groups of unlocking mechanisms 202 in the chemical fractionation device to respectively drive at least two components in one group of fixed components to move the corresponding target moving distance until each group of fixed components moves the corresponding target moving distance.

[0100] In some embodiments, please refer to Figure 1 At least one target component of the target battery 41 includes a first pole 42 and a second pole 43 , and a set of fixing components includes a first probe component 32 and a second probe component 33 .

[0101] The local position information of at least one target component of the target battery 41 includes a first distance between the first pole 42 and the second pole 43;

[0102] Optionally, the control system may include a display interface for interacting with the user, and the user may set the first distance between the first pole 42 and the second pole 43 of the target battery 41, a preset anti-collision compensation value, a preset centerline position, and preset avoidance position information through the display interface for interacting with the user;

[0103] The preset anti-collision compensation value is half of the distance between the components with the smallest distance among all components that need to be replaced, which is mainly used to prevent collision problems during the replacement process.

[0104] The preset centerline position is the center of the column of the tray of the chemical fractionation and storage equipment. The specific setting corresponding to it is made according to the type of different chemical fractionation and storage equipment, and no specific limitation is made here.

[0105] In an embodiment, a group of fixed components close to a preset centerline position is used as a reference column fixed component. Often, the reference column fixed component is the fixed component located in the middle of all groups of fixed components that need to be adjusted.

[0106] In some embodiments, after obtaining the initial position of each fixed component, the target moving distance of the reference group fixed component is determined based on the preset local position information of at least one target component in the target battery 41, the starting position information of the reference group fixed component, the preset anti-collision compensation value, and the preset centerline position. The target moving distance can be:

[0107] According to the starting position information of the reference group fixing component and the preset center line position, a first position offset of the target unlocking mechanism from the servo origin of the target unlocking mechanism to the preset center line position is obtained when the target unlocking mechanism is at the center of the first probe component 32, and a second position offset of the target unlocking mechanism from the servo origin of the target unlocking mechanism to the preset center line position when the target unlocking mechanism is at the center of the second probe component 33; wherein the target unlocking mechanism is one of the at least two groups of unlocking mechanisms 202.

[0108] Correcting the first position offset according to the first distance and a preset anti-collision compensation value to obtain a target moving distance of the first probe assembly of the reference group fixed assembly;

[0109] The second position offset is corrected according to the first distance and a preset anti-collision compensation value to obtain a target moving distance of the second probe assembly of the reference group fixing assembly.

[0110] For a more detailed understanding of the above method process, please refer to Figure 4 , Figure 4 A flowchart of another method for controlling a chemical fractionation device provided in an embodiment of the present application includes at least the following steps S301-S306:

[0111] Step S301: determining the starting position information of each group of fixed components;

[0112] Step S302: correcting the first position offset according to the first distance and a preset anti-collision compensation value to obtain a target moving distance of the first probe assembly of the reference group fixed assembly;

[0113] Step S303: Correcting the second position offset according to the first distance and the preset anti-collision compensation value to obtain a target moving distance of the second probe assembly of the reference group fixed assembly.

[0114] That is, according to step S302, the detailed steps of obtaining the target moving distance of the first probe assembly can be referred to Figure 5 , Figure 5 A flowchart for calculating a target moving distance of a first probe assembly provided in an embodiment of the present application includes at least the following steps S3021-S3021:

[0115] Step S3021: obtaining the absolute value of the difference between the first position offset and the preset value as the first difference.

[0116] Wherein, the preset value is half of the first distance;

[0117] Step S3022: obtaining an absolute value of a difference between the first difference value and a preset anti-collision compensation value as a target moving distance of the first probe assembly of the reference group fixed assembly.

[0118] For example, to understand the above calculation steps more clearly, please refer to Figure 6 , Figure 6A schematic structural diagram of a method for calculating a target moving distance of a first probe assembly is provided in an embodiment of the present application; the first probe assembly can be a left probe assembly or a right probe assembly, the first unlocking mechanism 22 is an unlocking mechanism with at least two groups of unlocking mechanisms 202 located on the left side, and the second unlocking mechanism 23 is an unlocking mechanism with at least two groups of unlocking mechanisms 202 located on the right side, wherein the unlocking mechanism on the left side corresponds to replacing the left probe assembly at the left position, and the unlocking mechanism on the right side corresponds to replacing the right probe assembly at the right position.

[0119] Optionally, the first unlocking mechanism 22 may also be the unlocking mechanism located on the right side among the at least two unlocking mechanisms, and the second unlocking mechanism 23 may also be the unlocking mechanism located on the left side among the at least two unlocking mechanisms, and no specific limitation is made here.

[0120] Optionally, the unlocking mechanism on the left side may also replace the right probe assembly at the right position, and the unlocking mechanism at the right position may also replace the left probe assembly at the left position, and no specific limitation is made here.

[0121] The following is a detailed explanation using an example in which the first unlocking mechanism is a set of unlocking mechanisms located at the left position among the at least two sets of unlocking mechanisms 202, the second unlocking mechanism is another set of unlocking mechanisms located at the right position among the at least two sets of unlocking mechanisms 202, and the first probe assembly 32 corresponds to the left probe assembly at the left position, and the second probe assembly 33 corresponds to the right probe assembly at the right position, wherein the direction from left to right is set as the positive direction.

[0122] The control system stores a first distance L between the left pole 521 and the right pole 522 of the target battery 41, a first position offset A1 from the servo origin of the target unlocking mechanism to a preset centerline position when the target unlocking mechanism is at the center of the first probe assembly 32, and a preset anti-collision compensation value B.

[0123] Among them, the preset anti-collision compensation value is half of the distance between the components with the smallest distance among all components that need to be replaced, which is mainly used to prevent collision problems during the replacement process. The preset center line position can be the center line of the chemical component capacity equipment tray, that is, the center position between the left pole 521 and the right pole 522 of the target battery 41 fixed by the reference group fixed component.

[0124] Determine the starting position information of each group of fixed components;

[0125] Since the first unlocking mechanism drives the left probe assembly accordingly, when the first probe assembly 32 is the left probe assembly, the target moving distance of the left probe assembly of the reference group fixing assembly is obtained by first obtaining the first difference, and then correcting it according to the preset anti-collision compensation value, that is: the absolute value of the difference between the first position offset A1 and half of the first distance of the preset target battery column, that is, L / 2, is the first difference, that is: the first difference = |A1-L / 2|, where " / " represents a division sign.

[0126] The absolute value of the difference between the first difference |A1-L / 2| and the preset anti-collision compensation value B is the target moving distance of the first probe assembly of the reference group fixed assembly, that is, the target moving distance of the left probe assembly of the reference group fixed assembly = |A1-L / 2|-B. Under normal circumstances, the first position offset A1 is greater than the preset value L / 2 and is much greater than the anti-collision compensation value B. Therefore, the target moving distance of the left probe assembly of the reference group fixed assembly = A1-L / 2-B.

[0127] In addition, when obtaining the target moving distance of the first probe assembly, it is also necessary to calculate the target moving distance of another probe assembly in the reference group fixed assembly, that is, the second probe assembly. For the above step S403, the detailed steps for calculating the target moving distance of the second probe assembly can be referred to. Figure 7 , Figure 7 A flowchart for calculating a target moving distance of a second probe assembly is provided in an embodiment of the present application. The flowchart includes at least the following steps S3031-S3032:

[0128] Step S3031: obtaining a sum of the second position offset and a preset value as a first sum value;

[0129] Step S3032: obtaining the sum of the first sum value and the preset anti-collision compensation value as the target moving distance of the second probe assembly of the reference group fixed assembly.

[0130] For example, to understand the above calculation steps more clearly, please refer to Figure 8 , Figure 8 A schematic structural diagram for calculating the target moving distance of the second probe assembly is provided in an embodiment of the present application. The following is a detailed explanation using the example where the first unlocking mechanism is one of the at least two unlocking mechanisms 202 located on the left side, the second unlocking mechanism is another of the at least two unlocking mechanisms 202 located on the right side, and the first probe assembly 32 corresponds to the left probe assembly, and the second probe assembly 33 corresponds to the right probe assembly, wherein the direction from left to right is set as the positive direction.

[0131] The control system stores a first distance L between the left pole 521 and the right pole 522 of the target battery 41, a second position offset A2 from the servo origin of the target unlocking mechanism to a preset centerline position when the target unlocking mechanism is at the center of the second probe assembly 33, and a preset anti-collision compensation value B.

[0132] Determine the starting position information of each group of fixed components;

[0133] Since the second unlocking mechanism drives the right probe assembly accordingly, when the second probe assembly 33 is the left probe assembly, the target moving distance of the right probe assembly of the reference group fixing assembly is obtained by first obtaining the first sum value, and then correcting it according to the preset anti-collision compensation value, that is: the sum of the second position offset A2 and half of the first distance of the preset target battery column, that is, L / 2, is obtained as the first sum value, that is: the first sum value = A1+L / 2, where " / " represents a division sign.

[0134] The absolute value of the difference between the first sum A1+L / 2 and the preset anti-collision compensation value B is obtained as the target moving distance of the second probe assembly, that is, the target moving distance of the right probe assembly of the reference group fixed assembly = A1+L / 2+B.

[0135] After obtaining the target movement distances of the first probe assembly 32 and the second probe assembly, that is, after obtaining the target movement distance of the reference group fixed assembly, it is also necessary to obtain the target movement distances of the other fixed assemblies 31 participating in the replacement, other than the fixed assemblies 31 of the reference column, based on the target movement distance of the reference group fixed assembly and the preset installation position information of the target battery 41, wherein the installation position information of the target battery 41 includes the second distance between the columns of target batteries 41; therefore, the target movement distances of the remaining groups of fixed assemblies, other than the reference group fixed assembly, can be determined as follows:

[0136] Step S304: obtaining a second difference between the target moving distance of the reference group fixed components and the second distance as the target moving distance of the first group fixed components,

[0137] The first group of fixed components is the fixed component on the left side of the reference group of fixed components;

[0138] Step S305: obtaining a second sum of the target moving distance of the reference group fixed component and the second distance as the target moving distance of the second column component fixed component 31;

[0139] Step S306: According to the target moving distance of each group of fixed components in at least one group of fixed components, control at least two groups of unlocking mechanisms 202 to move on the moving mechanism to respectively drive at least two components in one group of fixed components to move the corresponding target moving distance, until each group of fixed components moves the corresponding target moving distance.

[0140] In some embodiments, the detailed steps of obtaining the target moving distance of the first group of fixed components in step S304 can be referred to Figure 9 , Figure 9 A flowchart for calculating a target moving distance of a first group of fixed components is provided in an embodiment of the present application. The flowchart includes at least the following steps S3041-S3042:

[0141] Step S3041: obtaining a first sub-difference between the first probe assembly 32 and the second distance as a target moving distance of the third probe assembly in the first group of fixed assemblies;

[0142] Step S3042: obtaining a second sub-difference between the second probe assembly 33 and the second distance as a target moving distance of the fourth probe assembly in the first group of fixed assemblies.

[0143] For example, please refer to Figure 10 , Figure 10 This application provides a schematic structural diagram for calculating the target movement distance of a first group of fixed assemblies and a second group of fixed assemblies, including a first unlocking mechanism 22, a second unlocking mechanism 23, a target battery column 34 of the first group of fixed assemblies, a target battery column 35 of the reference group of fixed assemblies, a sensor 24, a left pole 521, and a right pole 522. B is a preset anti-collision compensation value, the target battery column 35 of the reference group of fixed assemblies represents the final position to which the reference group of fixed assemblies need to move, and the position of the target battery column 35 of the first group of fixed assemblies represents the final position to which the first group of fixed assemblies need to move. For example, the first unlocking mechanism 22 is the unlocking mechanism located on the left side of the at least two groups of unlocking mechanisms 202, the second unlocking mechanism 23 is the other unlocking mechanism located on the right side of the at least two groups of unlocking mechanisms 202, and the first probe assembly corresponds to the left probe assembly, the second probe assembly corresponds to the right probe assembly, the left probe assembly adapts to the left pole, and the right probe assembly adapts to the right pole. The positive direction is assumed to be from left to right, and the first group of fixed assemblies, the second group of fixed assemblies, and the reference group of fixed assemblies are not shown in the figure.

[0144] Among them, the third probe assembly in the first group of fixed components corresponds to the first probe assembly 32, and the fourth probe assembly in the first group of fixed components corresponds to the second probe assembly, that is, the third probe assembly of the first group of fixed components is the left probe assembly in the first group of fixed components, and the fourth probe assembly is the right probe assembly in the first group of fixed components. Therefore, when the column spacing between battery columns, that is, the second distance C, is stored in the control system, and the first group of fixed components is located on the left side of the reference group of fixed components, it can be easily obtained that the target moving distance of the left probe assembly in the first group of fixed components = |target moving distance of the first probe assembly-C|. The target moving distance of the right probe assembly in the first group of fixed components = |target moving distance of the second probe assembly - C|, that is, the target moving distance of the left probe assembly in the first group of fixed components = |||A1-L / 2|-B|-C|, the target moving distance of the right probe assembly in the first group of fixed components = |A2+L / 2+BC|. Normally, the first position offset A1 is greater than the preset value L / 2 and the column spacing C, and is much greater than the anti-collision compensation value B. Therefore, the target moving distance of the left probe of the first group of fixed components = A1-L / 2-BC, and the target moving distance of the right probe of the first group of fixed components = A2+L / 2+BC.

[0145] In addition, when obtaining the target moving distance of the first group of fixed components, that is, after obtaining the fixed components on the left side of the reference group of fixed components, it is also necessary to calculate the target moving distance of the fixed components on the right side of the reference group of fixed components, that is, the target moving distance of the second group of fixed components. For the above step S405, the detailed steps for calculating the target moving distance of the second group of fixed components can be referred to. Figure 11 , Figure 11 A flowchart for calculating a target moving distance of a second group of fixed components is provided in an embodiment of the present application. The flowchart includes at least the following steps S3051-S3052:

[0146] Step S3051: obtaining a first sub-sum value of the first probe assembly 32 and the second distance as a target moving distance of the third probe assembly in the second group of fixed assemblies;

[0147] Step S3052: obtaining a second sub-sum value of the second probe assembly 33 and the second distance as a target moving distance of the fourth probe assembly in the second group of fixed assemblies.

[0148] For example, please refer to Figure 10, including a target battery column 36 of the second group of fixed components, the position of the target battery column 36 of the second group of fixed components represents the final position to which the second group of fixed components needs to move, taking the first unlocking mechanism 22 as a group of unlocking mechanisms located on the left side of the at least two groups of unlocking mechanisms 202, the second unlocking mechanism 23 as another group of unlocking mechanisms located on the right side of the at least two groups of unlocking mechanisms 202, and the first probe assembly corresponding to the left probe assembly, the second probe assembly corresponding to the right probe assembly, the left probe assembly adapts to the left pole, and the right probe assembly adapts to the right pole as an example.

[0149] Among them, the third probe assembly in the second group of fixed components corresponds to the first probe assembly 32, and the fourth probe assembly in the second group of fixed components corresponds to the second probe assembly, that is, the third probe assembly of the fixed components in the second column is the left probe assembly in the second group of fixed components, and the fourth probe assembly is the right probe assembly in the second group of fixed components. Therefore, when the control system stores the column spacing between battery columns, that is, the second distance C, and the second group of fixed components is located on the right side of the reference group of fixed components, it can be easily obtained that the target moving distance of the left probe assembly in the second group of fixed components = |target moving distance of the first probe assembly + C|. The target moving distance of the right probe assembly of the reference group fixed assembly in the second group of fixed assemblies = |target moving distance of the second probe assembly + C|, that is, the target moving distance of the left probe assembly in the second group of fixed assemblies = ||A2-L / 2|-B|+C, the target moving distance of the right probe assembly in the second group of fixed assemblies = A2+L / 2+B+C. Under normal circumstances, the first position offset A1 is greater than the preset value L / 2 and the column spacing C, and is much greater than the anti-collision compensation value B. Therefore, the target moving distance of the left probe of the first group of fixed assemblies = A2-L / 2-B+C, and the target moving distance of the right probe of the first group of fixed assemblies = A2+L / 2+B+C.

[0150] After obtaining the target moving distances of the reference group fixed components, the first group fixed components and the second group fixed components, the control system needs to issue control instructions based on the target moving distances so that the programmable controller 12 controls at least two groups of unlocking mechanisms 202 on the unlocking structure to perform a change operation on the fixed component 31.

[0151] Based on the above-mentioned control method for the fractionation equipment, the present application also discloses a control system 10. Figure 12 , including a starting position acquisition module 121, a target distance acquisition module 122 and a control module 123, wherein:

[0156] Optionally, the target distance acquisition module 122 is further configured to acquire, based on the starting position information of the reference group fixed component and the preset centerline position, a first position offset of the target unlocking mechanism from the servo origin of the target unlocking mechanism to the preset centerline position when the target unlocking mechanism is at the center of the first probe assembly, and a second position offset of the target unlocking mechanism from the servo origin of the target unlocking mechanism to the preset centerline position when the target unlocking mechanism is at the center of the second probe assembly; wherein the target unlocking mechanism is one of the at least two groups of unlocking mechanisms; and

[0157] for correcting the first position offset according to the first distance and a preset anti-collision compensation value to obtain a target moving distance of the first probe assembly of the reference group fixed assembly; and

[0158] It is used to correct the second position offset according to the first distance and the preset anti-collision compensation value to obtain the target moving distance of the second probe component of the reference group fixed component.

[0162] Optionally, the moving distance acquisition module 122 is configured to acquire a second difference between the target moving distance of the reference group fixed component and the second distance as the target moving distance of the first group fixed component, wherein the first group fixed component is the fixed component to the left of the reference group fixed component; and

[0163] The second sum of the target moving distance of the reference group fixed component and the second distance is used to obtain the target moving distance of the second group fixed component, wherein the second group fixed component is the fixed component to the right of the reference group fixed component.

[0164] Optionally, the moving distance acquisition module 122 is configured to acquire a first sub-difference between the first probe assembly and the second distance as a target moving distance of the third probe assembly in the first group of fixed assemblies; and

[0165] The second sub-difference value used to obtain the second probe assembly and the second distance is the target moving distance of the fourth probe assembly in the first group of fixed assemblies.

[0166] Optionally, a moving distance acquisition module 122 is configured to acquire a first sub-sum of the distances between the first probe assembly and the second probe assembly as a target moving distance of the third probe assembly in the second group of fixed assemblies; and

[0167] The second sub-sum value for obtaining the second distance between the second probe assembly and the second probe assembly is the target moving distance of the fourth probe assembly in the second group of fixed assemblies.

[0168] Optionally, a target distance acquisition module 122 is configured to acquire target moving distances of other groups of fixed components based on the starting position information of each group of fixed components and the preset avoidance position information; wherein the other groups of fixed components are fixed components that do not participate in the changeover; and

[0169] Optionally, the control module 123 is configured to control at least two sets of unlocking mechanisms to drive other sets of fixing components to move corresponding target moving distances of the other sets of fixing components.

[0170] In some embodiments, the control system may include a host computer and a programmable controller, the host computer is connected to the programmable controller, and the programmable controller is connected to the chemical composition device. The host computer can realize the functions of the starting position acquisition module 121 and the target distance acquisition module 122, and the programmable controller can realize the function of the control module 123.

[0171] Exemplarily, the host computer is used to determine the starting position information of each group of fixed components; and, is used to determine the starting position information of each group of fixed components, and, is used to determine the target moving distance of the reference group fixed components based on the local position information of at least one target component of the preset target battery 41, the starting position information of the reference group fixed components, the preset anti-collision compensation value, and the preset center line position, wherein the at least one target component corresponds one-to-one to at least two components of the reference group fixed components; and,

[0172] for determining target moving distances of remaining fixed components in at least one group of fixed components except the reference group of fixed components according to the target moving distance of the reference group of fixed components and preset target battery installation position information;

[0173] A programmable controller is used to control at least two groups of unlocking mechanisms 202 in the chemical fractionation equipment 20 to respectively drive at least two components of one group of fixed components to move the corresponding target moving distance according to the target moving distance of each group of fixed components in at least one group of fixed components, until each group of fixed components moves the corresponding target moving distance, wherein one group of unlocking mechanisms located on the left side of the at least two groups of unlocking mechanisms 202 drives the components located on the left side of the at least two components, and the other group of unlocking mechanisms located on the right side of the at least two groups of unlocking mechanisms 202 drives the components located on the right side of the at least two components.

[0174] The host computer, also known as an embedded control system, is typically the "control center" or "monitoring center" of the entire battery control system. It is primarily responsible for interacting with users, collecting data, displaying real-time status, and performing system configuration and parameter settings. The host computer typically communicates with the host and slave devices via communication protocols, including but not limited to Controller Area Network (CAN), Recommended Standard 485 (RS485), and Transmission Control Protocol / Internet Protocol (TCP / IP). The host computer's functions include but are not limited to data monitoring and display, fault diagnosis and alarming, system configuration and parameter adjustment, and data logging and analysis.

The host computer can calculate the target moving distance of each group of fixed components based on the information, and send relevant control instructions to the programmable controller, so that the programmable controller controls at least two groups of unlocking mechanisms 202 of the component capacity device 20 to perform subsequent operations according to the received control instructions.

[0176] Programmable Logic Controllers (PLCs) primarily use programmable memory to store instructions for performing operations such as logic operations, sequential control, timing, counting, and arithmetic calculations. They also control various machines and processes through digital or analog input / output modules. Their core function is to execute pre-set programs, which can be customized and modified to meet the needs of industrial processes. They operate based on a scan cycle, periodically reading input signals, executing program logic, and updating output signals. This cyclical operation enables PLCs to respond to changes in industrial processes in real time, achieving precise automated control.

[0177] A programmable controller (PLC) consists of several components, including but not limited to a central processing unit (CPU), input / output (I / O) modules, a power supply module, and a programming device. The CPU is the brain of the PLC, responsible for executing programs stored in its memory. The I / O modules connect to external devices, such as sensors, actuators, and motors, to monitor and control industrial processes. The power supply module provides a stable power source for the PLC, ensuring its proper operation. The programming device is used to write, debug, and download control programs to the PLC.

[0178] In some embodiments, the present application further discloses a control method for a chemical fractionation device, which is applied to the chemical fractionation device. The chemical fractionation device includes a moving mechanism 201 and at least two sets of unlocking mechanisms 202. The positions of the two unlocking mechanisms in each set of unlocking mechanisms correspond to each other. The method includes:

[0179] Under the control of the control system 10, at least two sets of unlocking mechanisms 202 in the chemical fractionation device move on the moving mechanism to respectively drive at least two components of one set of fixed components to move a corresponding target moving distance, until each set of fixed components moves the corresponding target moving distance, wherein the set of unlocking mechanisms located on the left side of the at least two sets of unlocking mechanisms 202 drives the components located on the left side of the at least two components, and the other set of unlocking mechanisms located on the right side of the at least two sets of unlocking mechanisms 202 drives the components located on the right side of the at least two components;

[0181] Corresponding to the control method for a chemical fractionation device applied to a chemical fractionation device, the embodiment of the present application further discloses a chemical fractionation device, including a moving mechanism 201 and at least two sets of unlocking mechanisms 202, wherein the positions of the two unlocking mechanisms in each set of unlocking mechanisms correspond to each other, wherein:

[0182] The moving mechanism 201 is used to drive at least two sets of unlocking mechanisms 202 to move under the control of the control system 10;

[0183] At least two sets of unlocking mechanisms 202 are configured to move on the moving mechanism under the control of the control system 10 to respectively drive at least two components of one set of fixed components to move a corresponding target moving distance, until each set of fixed components moves the corresponding target moving distance, wherein the set of unlocking mechanisms located on the left side of the at least two sets of unlocking mechanisms 202 drives the components located on the left side of the at least two components, and the other set of unlocking mechanisms located on the right side of the at least two sets of unlocking mechanisms 202 drives the components located on the right side of the at least two components;

[0184] Among them, the target moving distance corresponding to each group of fixed components is determined based on the local position information of at least one target component of the preset target battery, the starting position information of the reference group fixed component, the preset anti-collision compensation value, the preset center line position and the preset installation position information of the target battery, wherein at least one target component corresponds one-to-one to at least two components of the reference group fixed component.

[0185] In order to more clearly understand the moving mechanism and unlocking mechanism in the above-mentioned chemical separation and storage device, the embodiment of the present application also discloses a schematic structural diagram of a moving mechanism and a schematic structural diagram of an unlocking mechanism. The moving mechanism and the unlocking mechanism are both integrated in the chemical separation and storage device.

Figure 14 This is a schematic diagram of an unlocking mechanism disclosed in an embodiment of the present application.

[0186] The mobile mechanism 201 is located on at least two sides of the chemical fractionation device and is arranged accordingly. As can be seen from the figure, the mobile mechanism 201 includes a servo motor 71, a left limit 72, and a right limit 73. The first unlocking mechanism 22 and the second unlocking mechanism 23 of the at least two sets of unlocking mechanisms 202 are located on the mobile mechanism 201. The programmable controller 12 is connected to the mobile mechanism 201 and is used to control the servo motor 71 to provide power to the at least two sets of unlocking mechanisms 202. Driven by the servo motor 71, the at least two sets of unlocking mechanisms 202 can move at a constant speed on the mobile mechanism 201. Specifically, when the mobile mechanism 201 drives the at least two sets of unlocking mechanisms 202 to move through the servo motor 71, the first unlocking mechanism 22 is located at the left position and drives the first probe assembly located at the left position, and the second unlocking mechanism 23 is located at the right position and drives the second probe assembly located at the right position. The first unlocking mechanism located at the left position can adapt to the position of the left limit 72, and the second unlocking mechanism located on the right can adapt to the position of the right limit 73. Therefore, the range of the changeover of the chemical component and content-forming equipment is expanded, and since two sets of unlocking mechanisms are used for the changeover, the changeover of at least two components in a set of fixed components can be completed within a period of time.

[0187] See also Figure 14 , Figure 14 This is a schematic structural diagram of an unlocking mechanism disclosed in an embodiment of the present application, which includes an unlocking cylinder 81, an insertion rod 82, a sensor 24, and a locking assembly 83, wherein:

[0188] When the locking assembly 83 is in an incorrect position or needs to be adjusted, it is necessary to unlock the lock in advance before it can be moved; at this time, the plug-in rod 82 is used to complete it, and the unlocking cylinder 81 is operated so that the cylinder 81 drives the plug-in rod 82 to move back and forth in a straight line. When the cylinder 81 is extended, the plug-in rod 82 moves to the locking assembly 83 and pushes it, causing the locking assembly 83 to move; because the end of the plug-in rod 82 that abuts the locking assembly 83 is conical, when the plug-in rod 82 is vertically inserted into the gap of the locking assembly 83, the locking assembly 83 moves in the direction away from the chemical separation and capacity equipment, thereby achieving unlocking.

[0189] When the cylinder 81 contracts, the corresponding plug-in rod 82 will also retract, causing the plug-in rod 82 to move away from the locking assembly 83. After the locking assembly 83 leaves the action of the plug-in rod 82, the locking assembly 83 will move toward the direction close to the chemical separation and capacity equipment to achieve position locking.

[0190] In the unlocking mechanism, a sensor obtains the position of the fixing component by detecting the position of the locking component.
