The embodiment of the application provides a chemical composition device which can be suitable for batteries with different specifications. This will be described below with reference to the accompanying drawings.

In the current lithium battery production process, the lithium battery is required to undergo a formation and separation process. The battery is formed by charging a certain current into the battery to activate active substances of the anode and the cathode of the battery, and finally the battery has discharge capacity. The formation is a process of activating the battery, and the capacity division is a process of classifying the battery according to the capacity of the electric energy after the battery is activated.

At present, a needle bed and a positioning disc are combined to divide the battery into components. However, in the related art, the compatibility of the device for dividing the battery into components is low, and batteries of different specifications cannot be applied, resulting in low production efficiency.

Referring to fig. 1 to 3, fig. 1 is a first structural schematic diagram of a chemical dividing device according to an embodiment of the present application, fig. 2 is a second structural schematic diagram of a chemical dividing device according to an embodiment of the present application, and fig. 3 is a structural schematic diagram of a drawing bracket, a first probe assembly, a second probe assembly, and a negative pressure assembly according to an embodiment of the present application.

The chemical dividing device 100 provided in the embodiment of the present application includes a chassis 10, an upper frame 20, a driving assembly 30, a drawing bracket 40, a first probe assembly 50 and a second probe assembly 60.

The chassis 10 is used for placing a battery. The upper frame 20 is liftably disposed at an upper side of the bottom chassis 10. The driving assembly 30 is disposed on the base frame 10 and connected to the upper frame 20 for driving the upper frame 20 to be lifted with respect to the base frame 10. The drawing bracket 40 is connected to the upper frame 20 such that the drawing bracket 40 is lifted together when the upper frame 20 is lifted. The first probe assembly 50 and the second probe assembly 60 are respectively arranged on the drawing bracket 40, the first probe assembly 50 is used for being abutted with the positive electrode of the battery, and the second probe assembly 60 is used for being abutted with the negative electrode of the battery.

It will be appreciated that when the upper frame 20 is lifted, the first probe assembly 50 and the second probe assembly 60 are lifted together, and when the upper frame 20 is lowered to a predetermined distance, the first probe assembly 50 is abutted against the positive electrode of the battery, and the second probe assembly 60 is abutted against the negative electrode of the battery, so that the formation process can be performed. Wherein the first and second probe assemblies 50 and 60 may be relatively close to or far from each other to adjust the spacing between the first and second probe assemblies 50 and 60.

It should be noted that the terms "first," "second," and the like in the description and in the claims and drawings are used for distinguishing between different objects and not for describing a particular sequential order, and are not to be construed as indicating or implying a relative importance or an amount of such technical features. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more features. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

It will be appreciated that the chemical composition apparatus 100 further includes a power cabinet (not shown) for providing power, which may be electrically connected to the first probe assembly 50 and the second probe assembly 60 via cables to provide power to the battery.

The first probe assembly 50 and the second probe assembly 60 are used as main execution mechanisms of lithium battery formation equipment, and the first probe assembly 50 and the second probe assembly 60 are used for being electrically connected with a lithium battery to be subjected to formation operation so as to charge the lithium battery just produced and activate active substances in the lithium battery, so that the lithium battery is activated, and the formed lithium battery can be charged and discharged normally.

For example, when the lithium battery needs to be formed, the upper frame 20 can be driven to descend by the driving assembly 30, so that the drawing bracket 40 on the upper frame 20 descends together, and further the first probe assembly 50 and the second probe assembly 60 arranged on the drawing bracket 40 can descend, so that the first probe assembly 50 is abutted with the positive electrode of the battery, and the second probe assembly 60 is abutted with the negative electrode of the battery, so that the lithium battery is formed.

In the chemical dividing device 100 according to the embodiment of the present application, the upper frame 20 for setting the first probe assembly 50 and the second probe assembly 60 is configured to be liftable, so that the upper frame 20 can be lifted to a proper height to bring the first probe assembly 50 into contact with the positive electrode of the battery, and the second probe assembly 60 into contact with the negative electrode of the battery. In this manner, the chemical composition apparatus 100 is enabled to better fit batteries of different height dimensions; also, the first and second probe assemblies 50 and 60 may be relatively close or far apart to adjust the spacing between the first and second probe assemblies 50 and 60, thereby enabling the chemical-mechanical device 100 to better fit batteries of different width dimensions.

In this way, under the mutual cooperation of the liftable structure of the upper frame 20 and the spacing adjustable structure of the first probe assembly 50 and the second probe assembly 60, the chemical composition device 100 can be suitable for batteries with different sizes and specifications, and the compatibility of the chemical composition device 100 is improved.

It will be appreciated that the lithium battery formation device may further include a battery tray (not shown in the drawings), through which the lithium battery is placed on the chassis 10, so as to better carry the lithium battery, thereby ensuring stability of electrical connection between the lithium battery and the probe assembly during formation operation.

It should be noted that, the battery tray is mostly made of metal materials, and the total weight of the battery can reach hundreds of kilograms, and in the related art, if the battery is driven to rise so that the battery is abutted against the probe above, a larger driving force is required due to the large gravity of the battery tray and the battery, a larger driving member 32 is required, and more energy is consumed, so that the cost is increased.

In the present application, the upper frame 20 is driven to move up and down to enable the first probe assembly 50 and the second probe assembly 60 above the battery to descend to be in contact with the anode and cathode of the battery, so that the upper frame 20 on the upper side is required to move down to press the probe assembly and the battery when the driving assembly 30 works, the upper frame 20 moves down under the action of gravity, and the probe and the battery can be tightly pressed only by supplementing part of power, thereby effectively saving power, and the driving member 32 with smaller specification can be used for driving. For example, a cylinder with a smaller inner diameter may be used for driving.

It should be noted that, in the related art, when a structure for driving the battery tray to rise is adopted, the battery tray is generally composed of an upper frame, a middle frame and a lower frame, the battery tray is arranged on the middle frame, the probe is fixed on the upper frame, and the driving member lifts the middle frame to drive the battery tray to rise, so that the battery and the probe are pressed together. It can be understood that the three-layer frame form adopted by the existing formation capacity movement mechanism has complex assembly structure and large load, is relatively unfavorable for the weight reduction of equipment, and the frame is mostly made of metal materials, has unbalanced overall weight, is unfavorable for assembly and wastes materials.

In the present application, the chemical composition unit 100 may be provided in a two-layered structure by driving the upper frame 20 to be lifted, i.e., the upper frame 20 for placing the battery and the first and second probe assemblies 50 and 60 are included, the middle frame is omitted, and only the upper and lower frames are provided, thereby simplifying the structure of the chemical composition unit 100, saving materials and design time, and reducing the weight of the overall structure. In addition, other parts are installed without lifting the middle layer frame during installation, so that the assembly and the later maintenance are convenient, and the assembly difficulty is reduced.

It will also be appreciated that the chassis 10 acts as a battery-carrying component on which components for supporting a battery tray may be provided. For example, referring to fig. 2, the chemical dividing device 100 may include a plurality of support columns 11 disposed at intervals, and the plurality of support columns 11 are disposed on the bottom chassis 10 for supporting a battery tray in which a battery is placed.

In this case, the battery tray is generally in a substantially rectangular structure, and thus, in order to more stably support the battery tray, the support posts 11 may be arranged in two rows, with the two rows of support posts 11 being located at both sides of the center axis of the battery tray, respectively.

In some embodiments, referring to fig. 2, in order to better determine whether the battery tray is in place, a first micro switch 12 may be further disposed on the chassis 10, where the first micro switch 12 is connected to a control system, and it may be understood that the control system is further connected to the driving assembly 30, and the control system may control the driving assembly 30 to drive the upper frame 20 to descend according to a signal of the first micro switch 12, so that the first probe assembly 50 abuts against an anode of the battery, and the second probe assembly 60 abuts against a cathode of the battery.

For example, when the battery tray is placed on the support post 11, the battery tray can be in contact with the first micro switch 12, at this time, the first micro switch 12 is electrically conducted, the first micro switch 12 transmits a signal to the control system, and the control system can control the driving assembly 30 to drive the upper frame 20 to descend according to the signal of the first micro switch 12, so that the first probe assembly 50 is abutted with the positive electrode of the battery, and the second probe assembly 60 is abutted with the negative electrode of the battery.

To prevent incorrect placement of the battery tray, an anti-reflection post 13 may also be provided on the chassis 10.

It should be noted that, the battery tray with the battery placed thereon is transported to the chassis 10 by an external mechanism, wherein, in order to enable the battery tray to be more stably placed on the support post 11, a guide post 14 may be provided on the chassis 10, and it is understood that the guide post 14 is provided with a guide slope to enable the battery tray to be stably guided to the support post 11.

In order to stably drive the upper frame 20 to be lifted, the structure related to the lifting will be described in detail with reference to the accompanying drawings.

Referring to fig. 2, the driving assembly 30 may include a floating joint 31 and a driving member 32, the floating joint 31 is disposed on the upper frame 20, the driving member 32 is disposed on the chassis 10, wherein a driving portion of the driving member 32 is connected to the floating joint 31, and the driving member 32 is used for driving the upper frame 20 to lift. It will be appreciated that the floating joint 31 alleviates the problem of eccentricity of the driving member 32, enables stable movement of the driving member 32 and the upper frame 20 within the allowable eccentricity range, and at the same time solves the problem of insufficient balance accuracy, maintaining the stable movement of the driving member 32 during operation.

The driving member 32 may be a cylinder or an electric cylinder, for example. For example, when the driving member 32 is a cylinder, the cylinder includes a cylinder body provided to the bottom chassis 10 and a piston rod slidably provided to the cylinder body, and one end of the piston rod is connected to the floating joint 31, and the upper frame 20 can be driven to be lifted and lowered by the expansion and contraction of the piston rod.

Of course, in some embodiments, the driving member may also be a driving device such as a screw module, which is not limited in this embodiment of the present application.

Referring to fig. 2, in order to enable the upper frame 20 to be stably lifted, the chemical dividing apparatus 100 may further include a guide assembly 70, the guide assembly 70 connecting the bottom chassis 10 and the upper frame 20, the guide assembly 70 for guiding the upper frame 20 when the upper frame 20 is lifted.

Illustratively, the upper frame 20 is provided with a relief hole 201, the guide assembly 70 includes a guide sleeve 71 and a guide rod 72, the guide sleeve 71 is disposed on the upper frame 20, and the guide sleeve 71 is disposed coaxially with the relief hole 201. One end of the guide rod 72 is connected to the chassis 10, and the other end is slidably inserted through the guide sleeve 71 and the escape hole 201. Thus, the upper frame 20 can be stably lifted and lowered by the cooperation of the guide sleeve 71 and the guide rod 72.

It will be appreciated that when the driving assembly 30 drives the upper frame 20 to descend to a preset height, the first and second probe assemblies 50 and 60 may abut against electrodes of the battery to perform a formation process. Wherein the upper frame 20 cannot be lowered infinitely, otherwise the probes in the first and second probe assemblies 50 and 60 are crushed.

Based on this, the chemical dividing device 100 may further include a limiting rod 15, where one end of the limiting rod 15 is connected to the chassis 10, and the other end of the limiting rod 15 is used to abut against the upper frame 20, so as to limit the upper frame 20. It will be appreciated that when the upper frame 20 is lowered into abutment with the stop bar 15, and the first and second probe assemblies 50 and 60 are now in abutment with the electrodes of the battery, if the drive assembly 30 still provides a downward moving drive force to the upper frame 20, the upper frame 20 is already in abutment with the stop bar 15 and is thus restrained by the stop bar 15, thus preventing the lower frame from continuing to descend and crush the probes in the first and second probe assemblies 50 and 60.

Illustratively, the limiting rod 15 includes a rod body 151 and a buffering pad 152, one end of the rod body 151 is connected to the chassis 10, the buffering pad 152 is adjustably disposed on the rod body 151 along a length direction of the rod body 151, and the buffering pad 152 is used for abutting against the upper frame 20 to limit the upper frame 20. In this way, the position of the cushion pad 152 in the length direction of the lever body 151 can be adjusted, so that the limit height of the upper frame 20 can be adjusted to accommodate batteries of different height sizes. Wherein, the cushion pad 152 may be screw-coupled to the lever body 151 by a screw rod, and thus, the position of the cushion pad 152 in the length direction of the lever body 151 may be adjusted by adjusting the depth of the screw coupling.

In some embodiments, referring to fig. 2, in order to better control the first probe assembly 50 and the second probe assembly 60 to charge the battery, an induction assembly 80 may be further disposed between the bottom frame 10 and the upper frame 20, the induction assembly 80 is connected with a control system, the control system is connected with a power cabinet, when the upper frame 20 is lowered in place, the induction assembly 80 sends out a signal, and the control system controls the power cabinet to charge the battery through the first probe assembly 50 and the second probe assembly 60 according to the signal sent out by the induction assembly 80.

The sensing assembly 80 includes a second micro-switch 81, a detecting bracket 82 and a sensing plate 83, the detecting bracket 82 is disposed on the chassis 10, the second micro-switch 81 is disposed on the detecting bracket 82, the sensing plate 83 is disposed on the upper frame 20, when the upper frame 20 descends to the point that the sensing plate 83 contacts with the second micro-switch 81, at this time, the second micro-switch 81 is electrically conducted, the second micro-switch 81 transmits signals to the control system, and the control system can control the power cabinet to charge the battery according to the signals of the second micro-switch 81.

The elevating structure of the upper frame 20 is described above, and the structure for adjusting the distance between the first and second probe assemblies 50 and 60 and the components related thereto will be described below with reference to the accompanying drawings.

It will be appreciated that the first and second probe assemblies 50 and 60 may be relatively moved closer to or farther from each other to adjust the spacing between the first and second probe assemblies 50 and 60, and that for ease of adjusting the spacing between the first and second probe assemblies 50 and 60, referring to fig. 3, the pull bracket 40, which is a structural member supporting the first and second probe assemblies 50 and 60, may include a bracket body 41 and a locking member 42, the bracket body 41 being coupled to the upper frame 20, the locking member 42 being provided to the bracket body 41.

Fig. 4 is a schematic structural diagram of the first probe assembly in fig. 3, and fig. 5 is a partial enlarged view of the first locking assembly and the locking member according to the embodiment of the application. The first probe assembly 50 includes a first mounting plate 51, a first probe 52 and a first locking assembly 53, the first mounting plate 51 is slidably connected to the bracket body 41, the first probe 52 is disposed on the first mounting plate 51, the first probe 52 is used for abutting against the positive electrode of the battery, it is understood that the first probe 52 may be disposed in a plurality, and the number of the first probes 52 corresponds to the number of the batteries. The first locking component 53 is disposed on the first mounting plate 51, and the first locking component 53 is configured to cooperate with the locking member 42 to lock or unlock the relative sliding between the first mounting plate 51 and the bracket body 41. When it is desired to adjust the spacing between the first and second probe assemblies 50, 60, the engagement between the first lock assembly 53 and the lock 42 may be unlocked to enable the first mounting plate 51 to slide relative to the bracket body 41 to adjust the spacing between the first mounting plate 51 and the second probe assembly 60 to achieve the adjustment of the spacing between the first and second probe assemblies 50, 60.

In order to facilitate the sliding of the first mounting plate 51, the bracket body 41 may be provided with a first slide rail 43, the first mounting plate 51 may be provided with a first slider 44, and the first slider 44 is slidably connected with the first slide rail 43.
