In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Currently, batteries on the market for commercial use are largely classified into pouch batteries and hard-shell batteries. Compared with a hard shell battery, the soft package battery has the advantages of high safety, light weight, large capacity and the like. Soft package batteries are commonly used in mobile devices such as mobile phones and tablet computers. In addition, the market proportion of laminate polymer battery in electric automobile is also being progressively improved, because laminate polymer battery's security is high, difficult burning explosion scheduling problem that appears has guaranteed electric automobile's safety, and laminate polymer battery quality is light, capacious, has alleviated the not enough problem of present electric automobile continuation of the journey mileage to a very big extent.

The plastic-aluminum membrane is laminate polymer battery's packaging material, plays the effect of protection electric core subassembly, and laminate polymer battery's electric core subassembly and electrolyte all hold in the plastic-aluminum membrane shell.

In the process of filling the electrolyte into the soft package battery, an opening needs to be opened on the aluminum-plastic film shell to serve as a liquid filling port, so that the liquid filling mechanism extends into the aluminum-plastic film shell to complete the filling of the electrolyte. In the prior art, the sucking disc is generally used for sucking the aluminum-plastic film shell to open the opening of the aluminum-plastic film shell, and because the aluminum-plastic film has certain toughness, when the sucking disc is removed from the aluminum-plastic film shell, the opening of the aluminum-plastic film shell can be shrunk and reduced, and the filling of electrolyte is influenced. Therefore, the sucking disc is required to be used for always adsorbing the aluminum-plastic film shell in the electrolyte filling process, and the liquid filling port is guaranteed to have enough opening all the time so as to allow the liquid filling mechanism to fill the liquid. However, the electrolyte has a certain volatility, and the volatilized electrolyte will block the suction holes of the sucker, so that the suction force of the sucker is reduced or even the suction force cannot be provided.

In view of this, the inventor has designed a pouch battery priming device through research, and this pouch battery priming device is through setting up first retaining mechanism, and first retaining mechanism includes first retaining arm and second retaining arm, and first retaining arm and second retaining arm are used for stretching into the notes liquid mouth of pouch battery and support the inner wall of notes liquid mouth department of pouch battery to guarantee at the in-process that electrolyte was annotated, annotate the state that the liquid mouth kept opening.

By using the liquid injection device for the soft package battery, the aluminum plastic film shell of the soft package battery does not need to be adsorbed by the sucking disc to be opened by maintaining the liquid injection port, so that the sucking disc and the liquid injection mechanism can keep a certain distance in the electrolyte injection process, and further the electrolyte is prevented from blocking the suction hole of the sucking disc.

The pouch battery liquid injection device of the present application is described in detail below with reference to the accompanying drawings.

In one aspect, as shown in fig. 1 and fig. 2, the application provides a pouch battery filling device 1, where the pouch battery filling device 1 includes a rack 11, a first clamping mechanism 12, a first holding mechanism 13, and a mechanical arm 14.

As shown in fig. 1-3, a first clamping mechanism 12 is disposed on the frame 11, and the first clamping mechanism 12 is used for clamping the pouch battery 2. The first holding mechanism 13 includes a first holding arm 131 and a second holding arm 132 that are oppositely disposed. The mechanical arm 14 is arranged on the rack 11, the first holding mechanism 13 is arranged at the executing end of the mechanical arm 14, and the mechanical arm 14 is used for driving the first holding mechanism 13 to extend into the liquid pouring opening 211 of the pouch battery 2, so that the first holding arm 131 and the second holding arm 132 support the inner wall at the liquid pouring opening 211 of the pouch battery 2.

For convenience of description of directions hereinafter, as shown in fig. 1, the X direction in fig. 1 is a first direction, and the first direction is a longitudinal direction of the rack 11, that is, a longitudinal direction of the pouch battery liquid injection device 1; the Y direction in the figure is a second direction, and the second direction is the height direction of the rack 11, that is, the height direction of the pouch battery liquid injection device 1; the Z direction in the figure is a third direction, and the third direction is the width direction of the rack 11, that is, the width direction of the pouch battery filling device 1.

It should be understood that the frame 11 is used to provide mounting locations for other structures, such as the first clamping mechanism 12 being disposed on the frame 11 and the robotic arm 14 being disposed on the frame 11. Illustratively, the frame 11 may be a frame structure, for example, the frame 11 may be formed by welding a plurality of profiles, or the frame 11 may also be formed by screwing a plurality of profiles through a threaded fastener. Specifically, the frame 11 may be made of steel and steel alloy, aluminum and aluminum alloy, or titanium and titanium alloy.

First fixture 12 is used for centre gripping laminate polymer battery 2 to indicate, and first fixture 12 centre gripping laminate polymer battery 2's plastic-aluminum membrane shell 21 to fix plastic-aluminum membrane shell 21, at the in-process to laminate polymer battery 2 filling electrolyte, make laminate polymer battery 2's plastic-aluminum membrane shell 21 can not take place to remove, also the notes liquid mouth 211 of laminate polymer battery 2 can not take place to remove, has guaranteed the stability of filling electrolyte in-process. For example, the first clamping mechanism 12 may include two oppositely disposed clamping plates, for example, two oppositely disposed clamping plates along the first direction X, and a receiving space for receiving the pouch battery 2 is defined between the two clamping plates. Of course, the first clamping mechanism 12 may further include more than two clamping plates, for example, four clamping plates, two of the four clamping plates are set in a group and are disposed oppositely along the first direction X, and two clamping plates located on the same side of the pouch battery 2 along the first direction X may be disposed at an interval along the third direction Z, so as to limit and clamp the pouch battery 2 within a relatively large range.

Further, use first fixture 12 to include two splint that set up relatively along first direction X as an example, place laminate polymer battery 2 between two splint, can be that frame 11 plays the supporting role to laminate polymer battery 2's plastic-aluminum membrane shell 21 along second direction Y, and two splint along first direction X butt respectively in laminate polymer battery 2's two relative sides of plastic-aluminum membrane shell 21 to the realization can to laminate polymer battery 2's centre gripping is fixed. It should be understood that the cell assembly 22 is accommodated in the aluminum-plastic film casing 21 of the pouch battery 2, and after the electrolyte is filled into the aluminum-plastic film casing 21, the electrolyte needs to sufficiently infiltrate the cell assembly 22, so that the two clamping plates of the first clamping mechanism 12 should not apply an excessive clamping force to the aluminum-plastic film casing 21, which results in that the electrolyte cannot smoothly enter the aluminum-plastic film casing 21 of the pouch battery 2. It can be understood that the two clamping plates of the first clamping mechanism 12 limit the pouch battery 2 between the two clamping plates to ensure that the aluminum plastic film casing 21 does not deflect or shift during the liquid injection process.

The first holding mechanism 13 includes a first holding arm 131 and a second holding arm 132 which are oppositely disposed, and for example, the first holding arm 131 and the second holding arm 132 may be oppositely disposed along the first direction X, for example, the first holding arm 131 and the second holding arm 132 are disposed on both sides of the first clamping mechanism 12 along the first direction X. Further, the first holding arm 131 and the second holding arm 132 are used for extending into the pouring port 211 of the pouch battery 2 to support the inner wall at the pouring port 211 of the pouch battery 2, i.e. to support the inner wall at the pouring port 211 of the aluminum plastic film casing 21 of the pouch battery 2, and in order to avoid the first holding arm 131 and the second holding arm 132 from scratching or puncturing the aluminum plastic film, the contact part of the first holding arm 131 and the second holding arm 132 with the aluminum plastic film casing 21 should be as smooth as possible and should not have edges and corners.

Specifically, the first holding arm 131 and the second holding arm 132 may be made of metal material such as iron, steel, aluminum or titanium, or the first holding arm 131 and the second holding arm 132 may also be made of plastic material such as nylon, ABS (Acrylonitrile-Butadiene-Styrene) engineering plastic, PC (Polycarbonate) plastic, PE (Polyethylene) plastic or PP (Polypropylene) plastic, or the first holding arm 131 and the second holding arm 132 may also be made of composite material such as carbon fiber or glass fiber.

It should be understood that, since the electrolyte is corrosive, the first and second holding

arms

131 and 132 should be made of a material with high corrosion resistance, and at least the portions of the first and second holding

arms

131 and 132 protruding into the pouch battery 2 should be made of a material with high corrosion resistance. For example, when the first and second retaining

arms

131 and 132 are made of iron or steel, other metal materials may be added to modify the first and second retaining

arms

131 and 132 according to actual use requirements. For example, adding metal manganese to form high manganese steel improves the corrosion resistance of the first and second holding

arms

131 and 132 while improving the wear resistance thereof, or adding metal chromium to form high chromium cast iron also improves the corrosion resistance of the first and second holding

arms

131 and 132. Of course, the first and second holding

arms

131 and 132 may be subjected to surface treatment to improve the corrosion resistance of the first and second holding

arms

131 and 132, for example, the surfaces of the first and second holding

arms

131 and 132 may be subjected to blackening treatment, or the surfaces of the first and second holding

arms

131 and 132 may be subjected to surface impregnation of tungsten carbide, or the surfaces of the first and second holding

arms

131 and 132 may be subjected to surface impregnation of chromium carbide.

It should be noted that, regardless of whether the robot arm 14 is driven by a single shaft or by multiple shafts, it is sufficient that the robot arm 14 can drive the first holding mechanism 13 to extend into the pouring port 211 of the pouch battery 2.

Specifically, taking the robot 14 as a linear motion robot 14 driven by a single shaft as an example, the robot 14 includes a driving member and an actuator, the actuator serves as an actuator of the robot 14, and the first holding mechanism 13 is provided in the actuator. Illustratively, the driving member may be a pneumatic cylinder, and drives the actuator and the first retaining mechanism 13 to move relative to the frame 11 by pneumatic means. In other embodiments of the present application, the driving member may be a hydraulic cylinder, and the actuator and the first retaining mechanism 13 are hydraulically driven to move relative to the frame 11. In further embodiments of the present application, the driving member may be a linear motor, or a motor and a lead screw nut, etc. which can drive the actuator and the first retaining mechanism 13 to move along the second direction Y relative to the frame 11. In some further embodiments of the present application, the driving member may be a driving method in which the motor is engaged with a rack-and-pinion transmission mechanism, or a driving method in which the motor is engaged with a belt transmission mechanism or a chain transmission mechanism.

The utility model provides a laminate polymer battery priming device 1, through setting up first retaining mechanism 13, first retaining mechanism 13 includes first retaining arm 131 and second retaining arm 132, first retaining arm 131 and second retaining arm 132 are used for stretching into laminate polymer battery 2's notes liquid mouth 211 and support the inner wall of laminate polymer battery 2's notes liquid mouth 211 department, in order to guarantee at the in-process that electrolyte was annotated, it keeps the state of opening to annotate liquid mouth 211, and need not use sucking disc to adsorb laminate polymer battery 2's plastic-aluminum membrane shell 21 to open in order to maintain notes liquid mouth 211, make the in-process sucking disc that electrolyte was annotated and annotate liquid mechanism and can keep certain distance, and then avoided the suction hole of electrolyte jam sucking disc.

As shown in fig. 4, in some embodiments of the present application, the first retaining mechanism 13 further includes a first base 133, a first slide rail 134, a first slider 135, and a second slider 136. Wherein the first base 133 is disposed at the executing end of the robot 14, and the first slide rail 134 is disposed on the first base 133 along the first direction X. The first slider 135 is slidably connected to the first slide rail 134, the first holding arm 131 is disposed on the first slider 135, the second slider 136 is slidably connected to the first slider 135, and the second holding arm 132 is disposed on the second slider 136.

For example, in the case where the robot arm 14 is a linear motion robot arm 14 driven by a single shaft and the execution end of the robot arm 14 moves in the second direction Y with respect to the rack 11, the first base 133 is provided at the execution end of the robot arm 14, that is, the first base 133 is movable in the second direction Y with respect to the rack 11. Further, the first slide rail 134 is disposed on the first base 133, and the first slide rail 134 moves along the second direction Y along with the first base 133.

Specifically, the installation direction of the first slide rail 134 may be determined according to the direction in which the first clamping mechanism 12 clamps the pouch battery 2 and the opening direction of the liquid inlet 211 of the pouch battery 2. For example, when the first clamping mechanism 12 clamps both sides of the aluminum plastic film casing 21 of the pouch battery 2 along the first direction X, the liquid inlet 211 of the pouch battery 2 is also relatively opened along the first direction X. At this time, the first slide rail 134 may be disposed on the base along the first direction X, and accordingly, the first slider 135 and the second slider 136 may be slidably coupled to the first slide rail 134 along the first direction X, so that the first holding arm 131 and the second holding arm 132 may move along the first direction X with the first slider 135 and the second slider 136, respectively, for example, the first holding arm 131 and the second holding arm 132 may approach or separate from each other along the first direction X.

Further, when the first base 133 moves in the second direction Y, the first slide rail 134, the first slider 135 and the second slider 136 move along with the first base 133 in the second direction Y, and at this time, the first holding arm 131 and the second holding arm 132 can move in the second direction Y, and the first holding arm 131 and the second holding arm 132 can also move along with the first slider 135 and the second slider 136 in the first direction X. Illustratively, the first and second holding

arms

131 and 132 are located on both sides of the pouch cell 2 in the first direction X and the first and second holding

arms

131 and 132 are located above (laterally above) the pouring outlet 211 of the pouch cell 2, and in order to enable the first and second holding

arms

131 and 132 to protrude into the pouring outlet 211 of the pouch cell 2 more accurately, the first and second holding

arms

131 and 132 may be downwardly close to the pouch cell 2 in the second direction Y while the first and second holding

arms

131 and 132 are close to each other in the first direction X so that the first and second holding

arms

131 and 132 can protrude into the pouring outlet of the pouch cell 2 accurately, and thereafter, as the first and second holding

arms

131 and 132 continue to move down, the first and second holding

arms

131 and 132 are away from each other in the second direction Y so that the first and second holding

arms

131 and 132 can abut against the inner wall of the pouring outlet 211 of the pouch cell 2, so as to stably keep the pouring outlet 211 of the pouch battery 2 open. It should be understood that while the first and second holding

arms

131 and 132 are moved away from the pouch battery 2 upward in the second direction Y, the first and second holding

arms

131 and 132 may be moved toward each other in the first direction X so that the first and second holding

arms

131 and 132 can be withdrawn from the pouring outlet 211 of the pouch battery 2 without being damaged, and thereafter, as the first and second holding

arms

131 and 132 continue to move upward, the first and second holding

arms
