Description

Technical Field

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

[0002] Energy conservation and emission reduction are the key to sustainable development, which has promoted the adjustment of energy structure and the development and application of battery technology. The key to the development of battery technology lies in electrochemical energy storage technology, which has been widely used in portable electronics, electric vehicles and energy storage systems due to its high energy density, good cycle capacity, high operating voltage, environmental protection and low self-discharge.

[0003] In the battery production system, the battery module and the case need to be flipped as a whole. However, in the existing battery production system, a lifting mechanism is directly used to flip the battery module and the case as a whole. However, the overall weight of the battery module and the case is relatively large. If a lifting mechanism is directly used for lifting and flipping, there will be great risks. Summary of the invention

[0004] The main purpose of this application is to provide a battery assembly system and a battery assembly method, aiming to solve the above-mentioned technical problems existing in the prior art.

[0005] To solve the above problems, the present application provides a battery assembly system, which includes a first transport mechanism, a lifting mechanism, a flipping mechanism and an inverted mechanism; the lifting mechanism is used to invert the box body onto the battery module of the inverted mechanism; the inverted mechanism is used to assemble the inverted box body and the battery module into an inverted battery pack, and is used to transport the inverted battery pack to the first transport mechanism; the first transport mechanism is used to transport the inverted battery pack to the flipping mechanism; the flipping mechanism is used to flip the inverted battery pack into an upright battery pack. Thus, the lifting mechanism inverts the box onto the battery module of the inverted mechanism, assembles the battery module and the box through the inverted mechanism to obtain an inverted battery pack, and transports the inverted battery pack to the flipping mechanism through the inverted mechanism and the first transport mechanism respectively, so that the flipping mechanism flips the inverted battery pack into an upright battery pack. There is no need for the lifting mechanism to lift and flip the overall structure of the battery module and the box, which can alleviate the greater safety risks caused by the heavy weight lifted by the lifting mechanism, and can also alleviate the risk of large relative displacement between the battery module and the box due to the unstable lifting process of the lifting mechanism, thereby improving product yield.

[0006] In some embodiments, the battery module is carried on a carrier, and the carrier is carried on a first transport mechanism, so that the inverted battery pack and the carrier are transported to the flip mechanism through the first transport mechanism; the battery assembly system also includes a second transport mechanism, and the second transport mechanism is used to carry a box to transport the upright battery pack. As a result, the battery module is carried on the carrier, and the box is inverted on the battery module, which can provide better protection for the battery module through the box and the carrier. And the carrier is carried on the first transport mechanism, which can facilitate the first transport mechanism to cooperate with the carrier to stably transport the inverted battery pack, and the box is carried on the second transport mechanism, which can facilitate the second transport mechanism to cooperate with the box to stably transport the upright battery pack.

[0007] In some embodiments, the flipping mechanism clamps the load and the box to flip the inverted battery pack into an upright battery pack. Thus, the flipping mechanism clamps the load and the box, and can stably clamp and flip the battery module without damaging the battery module. Compared with the overall structure of lifting and flipping the battery module and the box by the lifting mechanism, the safety during flipping can be improved.

[0008] In some embodiments, the flipping mechanism is used to separate the upright battery pack from the object being carried, the second transport mechanism carries the box to transport the upright battery pack, and the first transport mechanism is used to transport the object being carried. Thus, after the flipping mechanism flips the inverted battery pack into an upright battery pack, the upright battery pack and the object being carried can be directly separated, making it easier to transport and process the upright battery pack and the object being carried separately, alleviating the obstruction of subsequent operations by the object being carried, and improving the assembly efficiency of the battery module.

[0009] In some embodiments, the battery assembly system further includes a pressurizing mechanism, and the second transport mechanism transports the box and the battery module to the pressurizing mechanism, and the pressurizing mechanism is used to press the box and the battery module. Thus, by pressing the battery module and the box, the fixing effect of the battery module and the box can be improved, and the assembly efficiency of the battery module can be improved.

[0010] In some embodiments, at least one of the first transport route of the first transport mechanism and the second transport route of the second transport mechanism is in a ring shape. Thus, compared with a traditional single straight transport route, at least one of the first transport route and the second transport route is in a ring shape, which can make the occupied area more concentrated and alleviate the problem of dispersed logistics distribution and large occupied area.

[0011] In some embodiments, the flipping mechanism is located on the first transport route and the second transport route. Thus, the flipping mechanism is located on both the first transport route and the second transport route, which can facilitate the first transport mechanism to transport the inverted battery pack to the flipping mechanism, and facilitate the second transport mechanism to transport the upright battery pack away from the flipping mechanism, thereby improving the overall transportation efficiency, and further alleviating the problem of scattered logistics distribution and large floor space.

[0012] In some embodiments, the second transport route is annular, and the hoisting mechanism flips the box outside the loop of the second transport route. Thus, the hoisting mechanism flips the box outside the loop of the second transport route, which can alleviate the risk of interference caused by the second transport route when flipping the box.

[0013] In some embodiments, the battery assembly system further includes a glue coating mechanism, which is used to coat the box with adhesive, and the second transport mechanism is used to transport the box after coating with adhesive so that the hoisting mechanism can lift the box. Thus, the glue coating mechanism coats the box with adhesive, and the box and the battery module can be bonded by the adhesive, thereby improving the stability of the flip-down battery pack, improving the firmness of the bonding and fixing of the battery module and the box, and ensuring the stability and safety of the battery module.

[0014] In some embodiments, the station where the lifting mechanism lifts the box, the station where the inverting mechanism is located, and the station where the first transport mechanism receives the inverted battery pack are in the same direction. Thus, the station where the lifting mechanism lifts the box, the station where the inverting mechanism is located, and the station where the first transport mechanism receives the inverted battery pack are in the same direction, which can make the layout of the battery assembly system more reasonable and alleviate the problem of scattered logistics distribution and large floor space.

[0015] In order to solve the above problems, the present application provides a battery assembly method of the battery assembly system as described above, the battery assembly method comprising: in response to the hoisting mechanism, the box is inverted on the battery module to obtain an inverted battery pack, and the inverted battery pack is transported to the first transportation mechanism by the inverting mechanism; in response to the inverted battery pack being located at the first transportation mechanism, the inverted battery pack is transported to the flipping mechanism by the first transportation mechanism; in response to the inverted battery pack being transported to the flipping mechanism, the inverted battery pack is flipped into an upright battery pack by the flipping mechanism. Thus, the first transportation mechanism transports the inverted battery pack to the flipping mechanism, and the flipping mechanism flips the inverted battery pack into an upright battery pack, and the overall structure of the battery module and the box can be lifted and flipped without the need for the hoisting mechanism, which can alleviate the greater safety risks caused by the heavy weight of the hoisting mechanism, and can also alleviate the risk of large relative displacement of the battery module and the box caused by the unstable hoisting process of the hoisting mechanism, thereby improving the product yield.

[0016] In some embodiments, the battery assembly method further includes: responding to the flipping mechanism flipping the inverted battery pack into an upright battery pack, separating the upright battery pack from the carrier through the flipping mechanism; and transporting the upright battery pack and the carrier separately from the flipping mechanism. Thus, after the flipping mechanism flips the inverted battery pack into an upright battery pack, the upright battery pack and the carrier can be directly separated, which facilitates the transportation and processing of the upright battery pack and the carrier separately, alleviates the carrier from interfering with subsequent operations, and improves the assembly efficiency of the battery module.

[0017] In some embodiments, the steps of transporting the upright battery pack and the load from the flip mechanism respectively include: receiving the upright battery pack at the flip mechanism by the second transport mechanism to transport the upright battery pack away from the flip mechanism; in response to the upright battery pack being transported away from the flip mechanism, receiving the load at the flip mechanism by the first transport mechanism to transport the load away from the flip mechanism. Thus, the upright battery pack is first transported away from the flip mechanism by the second transport mechanism, and then the load is transported away from the flip mechanism by the first transport mechanism, making the entire operation layout more reasonable, alleviating the load from interfering with subsequent operations, and improving the assembly efficiency of the battery module.

[0018] In some embodiments, after receiving the upright battery pack at the flipping mechanism by the second transport mechanism to transport the upright battery pack away from the flipping mechanism, the battery assembly method includes: transporting the upright battery pack to the pressing mechanism by the second transport mechanism; and pressing the box and the battery module by the pressing mechanism. Thus, by pressing the battery module and the box by the pressing device, the fixing effect of the battery module and the box can be improved, and the assembly efficiency of the battery module can be improved.

[0019] In some embodiments, in response to the hoisting mechanism inverting the box body on the battery module to obtain an inverted battery pack, the step of transporting the inverted battery pack to the first transport mechanism through the inverted mechanism includes: transporting the box body to the lifting station through the second transport mechanism; the hoisting mechanism lifts the box body at the lifting station; flipping the box body through the hoisting mechanism; inverting the flipped box body on the battery module of the inverted mechanism; assembling the inverted box body and the battery module into an inverted battery pack through the inverted mechanism; and transporting the inverted battery pack to the first transport mechanism through the inverted mechanism. Thus, transporting the box body to the lifting station through the second transport mechanism can facilitate the hoisting operation of the box body by the hoisting mechanism, improve the automation of battery assembly, and the hoisting mechanism only needs to lift and flip the box body. Compared with the hoisting mechanism lifting and flipping the overall structure of the battery module and the box body, it can alleviate the greater safety risks caused by the heavy weight of the hoisting mechanism, and at the same time, it can also alleviate the risk of large relative displacement of the battery module and the box body caused by the unstable hoisting process of the hoisting mechanism, thereby improving the product yield.

[0020] In some embodiments, the step of transporting the box to the lifting station by the second transport mechanism includes: transporting the box to the gluing mechanism by the second transport mechanism; gluing the box by the gluing mechanism; and transporting the gluing box to the lifting station by the second transport mechanism. Thus, by coating the box with adhesive by the gluing mechanism, the box and the battery module can be bonded by the adhesive, thereby improving the stability of the flip-down battery pack and alleviating the risk of a large displacement of the battery module in the box.

[0035] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0036] Batteries mentioned in this field can be divided into disposable batteries and rechargeable batteries according to whether they are rechargeable. Disposable batteries (Primary Battery) are also called "disposable" batteries and original batteries, because after they are exhausted, they can no longer be recharged and can only be discarded. Rechargeable batteries are also called secondary batteries (Secondary Battery) or secondary batteries, storage batteries. The manufacturing materials and processes of rechargeable batteries are different from those of primary batteries. Its advantage is that it can be recycled many times after charging, and the output current load capacity of rechargeable batteries is higher than that of most disposable batteries. The common types of rechargeable batteries at present are: lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries. Lithium-ion batteries have the advantages of light weight, large capacity (the capacity is 1.5 to 2 times that of nickel-metal hydride batteries of the same weight), no memory effect, and have a very low self-discharge rate. Therefore, even though the price is relatively high, they are still widely used. Lithium-ion batteries are currently also widely used in pure electric vehicles and hybrid vehicles. The capacity of lithium-ion batteries used for this purpose is relatively low, but they have a larger output and charging current, and also have a longer service life, but the cost is higher.

[0037] The battery described in the embodiments of the present application refers to a rechargeable battery or a disposable battery. The embodiments disclosed in the present application will be described below mainly by taking a lithium-ion battery as an example. It should be understood that the embodiments disclosed in the present application are applicable to any other appropriate type of rechargeable battery. The battery mentioned in the embodiments disclosed in the present application can be directly or indirectly applied to an appropriate device to power the device.

[0038] The battery can be applied to an electrical device, and the electrical device can provide electrical energy through the battery to realize the corresponding function. The electrical device may include but is not limited to mobile phones, tablets, laptops, electric toys, electric tools, battery cars, electric cars, ships, spacecraft, etc. Among them, the electric toys may include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys and electric airplane toys, etc., and the spacecraft may include airplanes, rockets, space shuttles and spacecrafts, etc.

[0039] The battery may include a battery module and a box. The battery module may be arranged in the box so as to provide better protection for the battery module. The battery module may include a plurality of battery cells. The plurality of battery cells may be connected in series, in parallel or in mixed connection. Mixed connection means that the plurality of battery cells are both connected in series and in parallel. The plurality of battery cells may be directly connected in series, in parallel or in mixed connection, and then the whole formed by the plurality of battery cells may be accommodated in the box. Of course, the battery module may also be a battery module formed by first connecting a plurality of battery cells in series, in parallel or in mixed connection, and then a plurality of battery modules may be connected in series, in parallel or in mixed connection to form a battery module.

[0040] Among them, the production methods of battery cells include stacking and winding, that is, battery cells are divided into stacking cells and winding cells. Stacking batteries have uniform current collection effect, small internal resistance, and large specific power, but in order to improve precision, the mold precision requirements are extremely high, the equipment investment is high, and the process is relatively complex, and the production efficiency is low. Winding batteries are simple to make, and the production and assembly processes have general requirements for equipment precision, high production efficiency, and low cost. In terms of performance, wound batteries have excellent high and low temperature performance, very fast charging, ultra-long life, stable high output voltage, strong structure, and strong shock resistance.

[0041] In the battery production system, the battery module and the box need to be turned over as a whole. However, in the relevant battery production system, the battery module and the box are turned over as a whole directly by a hoisting mechanism. However, the overall weight of the battery module and the box is large. If the hoisting mechanism is directly used for hoisting and turning, there will be great risks. At the same time, the hoisting process may be unstable, resulting in relative displacement of the battery module and the box, so that the battery module is offset when entering the box, which does not meet the quality requirements of the product, etc.

[0042] In order to solve the technical problems existing in the related art, the present application provides a battery assembly system, see Figure 1 , Figure 1 It is a first structural schematic block diagram of a battery assembly system according to one or more embodiments of the present application.

[0043] The battery assembly system 10 includes a first transportation mechanism 100 , a hoisting mechanism 200 , a turning mechanism 400 and an inverting mechanism 300 .

[0044] The hoisting mechanism 200 may include but is not limited to a crane, for example, the hoisting mechanism 200 may be a mobile crane with lattice jib, a bridge crane, a gantry crane, a mobile crane, etc. The hoisting mechanism 200 may suspend an object, and then move the suspended object from one position to another, or perform operations such as flipping the suspended object.

[0045] The first transport mechanism 100 may include but is not limited to intelligent transport vehicles, intelligent transport robots and unmanned guided vehicles, for example, the first transport mechanism 100 may be an unmanned guided vehicle AGV (Automated Guided Vehicle), which may include electromagnetic, optical or visual automatic guidance devices, so that the unmanned guided vehicle can travel along a predetermined route or a route planned by itself, and thus can be used as a transport vehicle with a carrying function. The first transport mechanism 100 can carry items to transport the items from one location to another along a predetermined transport track.

[0046] The inverting mechanism 300 can be used to provide a working platform for carrying articles and to assemble two articles on the working platform. The inverting mechanism 300 can also push the carried articles to the first transport mechanism 100 so that the first transport mechanism 100 can transport the articles.

[0047] The flipping mechanism 400 can flip the object. For example, the flipping mechanism 400 can first clamp the object and then flip the object along a certain direction at a specific angle.

[0048] Combination Figure 2 , Figure 2 It is a disassembled schematic diagram of a battery module 30 , a box 20 , and a carrier 40 according to one or more embodiments of the present application.

[0049] The hoisting mechanism 200 is used to invert the box 20 onto the battery module 30 of the inverting mechanism 300. The box 20 may include but is not limited to a frame chassis or a battery box, etc. When the box 20 is a frame chassis, the battery module 30 and the frame chassis are integrated, that is, CTC (Cell to Chassis) technology is applicable, which can reduce the space occupancy rate of the battery, increase the battery capacity per unit space, increase the cruising range, and at the same time enhance the structural strength of the frame chassis and improve the safety of the vehicle.

[0050] The battery module 30 can be placed on the flip mechanism 300 in advance. When the battery module 30 needs to be assembled with the box 20, the box 20 can be suspended to the battery module 30 by the lifting mechanism 200. Specifically, the box 20 can have an inwardly recessed receiving groove. In the direction of gravity, when the opening of the receiving groove faces upward, the box 20 can be considered to be upright, and when the opening of the receiving groove faces downward, the box 20 can be considered to be inverted. The box 20 is inverted on the battery module 30 of the flip mechanism 300, which can be understood as: the position of the battery module 30 remains unchanged, and the box 20 approaches the battery module 30 from top to bottom along the direction of gravity until the battery module 30 is accommodated in the receiving groove of the box 20. Among them, the lifting mechanism 200 can flip the box 20 during the process of suspending the box 20, so as to facilitate the inverted placement of the box 20 on the battery module 30 of the flip mechanism 300.

[0051] The inverted mechanism 300 is used to assemble the inverted box 20 and the battery module 30 into an inverted battery pack, and to transport the inverted battery pack to the first transport mechanism 100; the first transport mechanism 100 is used to transport the inverted battery pack to the flip mechanism 400. When the box 20 is inverted on the battery module 30 along the gravity direction, the overall structure after the battery module 30 and the box 20 are kept relatively fixed can be understood as an inverted battery pack. The inverted mechanism 300 can provide a working platform for carrying items, and the battery module 30 can be placed on the working platform of the inverted mechanism 300, so that the hoisting mechanism 200 can invert the box 20 on the battery module 30. Among them, the inverted mechanism 300 can also include some auxiliary structures, for example, the inverted mechanism 300 can also include related structures for positioning the battery module 30, related structures for guiding the box 20 to be inverted on the battery module 30, related structures for adjusting the position of the inverted battery pack, etc., so that the inverted box 20 and the battery module 30 are combined into an inverted battery pack through the inverted mechanism 300. The first transport mechanism 100 can be moved to a predetermined position. After the inverted battery pack is formed, the inverted assembly mechanism 300 can guide the inverted battery pack to move onto the first transport mechanism 100 , so that the first transport mechanism 100 can move the inverted battery pack to the flip mechanism 400 .

[0052] The flipping mechanism 400 is used to flip the inverted battery pack into an upright battery pack. An upright battery pack can be understood as a battery module 30 located above the box 20 in the direction of gravity, and the battery module 30 can be carried by the box 20. When it is detected that the inverted battery pack is transported to a predetermined position by the first transport mechanism 100, the flipping mechanism 400 can clamp the inverted battery pack and flip the inverted battery pack in a certain direction at a specific angle, for example, the inverted battery pack can be flipped 180° to form an upright battery pack.

[0053] Through the above-mentioned embodiment, the lifting mechanism 200 inverts the box 20 on the battery module 30 of the inversion mechanism 300, assembles the battery module 30 and the box 20 through the inversion mechanism 300 to obtain an inverted battery pack, and transports the inverted battery pack to the flipping mechanism 400 through the inversion mechanism 300 and the first transportation mechanism 100 respectively, so that the flipping mechanism 400 flips the inverted battery pack into an upright battery pack. There is no need for the lifting mechanism 200 to lift and flip the overall structure of the battery module 30 and the box 20, which can alleviate the greater safety risks caused by the heavy weight hoisted by the lifting mechanism 200, and can also alleviate the risk of large relative displacement between the battery module 30 and the box 20 caused by the unstable hoisting process of the lifting mechanism 200, thereby improving the product yield.

[0054] See also Figure 3 , Figure 3 is a second structural schematic block diagram of a battery assembly system 10 according to one or more embodiments of the present application.

[0055] The battery module 30 is carried on the carrier 40, and the carrier 40 is carried on the first transport mechanism 100, so that the inverted battery pack and the carrier 40 are transported to the flipping mechanism 400 through the first transport mechanism 100; the battery assembly system 10 also includes a second transport mechanism 500, which is used to carry the box 20 to transport the upright battery pack.

[0056] The carrier 40 may include but is not limited to a battery tray. The carrier 40 may be used to carry the battery module 30. The carrier 40 may be provided with a fixing structure for fixing the battery module 30. For example, the carrier 40 may be formed with a positioning groove. The radial dimension of the positioning groove may be slightly larger than the radial dimension of the battery module 30. When the carrier 40 carries the battery module 30, the battery module 30 is partially accommodated in the positioning groove. The battery module 30 may be fixed by the carrier 40. In the initial state, the carrier 40 is located on the inversion mechanism 300. The battery module 30 may be carried on the carrier 40. When the hoisting mechanism 200 inverts the box 20 onto the battery module 30 of the inversion mechanism 300 to obtain an inverted battery pack, the inversion mechanism 300 transports the carrier 40 and the inverted battery pack to be received by the first transport mechanism 100, so that the first transport mechanism 100 can transport the carrier 40 and the inverted battery pack to the flip mechanism 400. Among them, the first transport mechanism 100 can be provided with a structure matching the load 40. When the first transport mechanism 100 transports the load 40, the first transport mechanism 100 can have a better fixing effect on the load 40, thereby improving the stability of the first transport mechanism 100 in the process of transporting the inverted battery pack.

[0057] The second transport mechanism 500 may include but is not limited to an intelligent transport vehicle, an intelligent transport robot and an unmanned guided vehicle, for example, the second transport mechanism 500 may be an unmanned guided vehicle AGV (Automated Guided Vehicle), which may include an electromagnetic, optical or visual automatic guidance device, so that the unmanned guided vehicle can travel along a predetermined route or a route planned by itself, and thus can be used as a transport vehicle with a carrying function. The second transport mechanism 500 can carry the box 20 to transport the box 20 from one position to another along a predetermined transport track. The second transport mechanism 500 can be used to transport the box 20 to a position that is convenient for the hoisting mechanism 200 to lift, and can be used to receive the upright battery pack at the flip mechanism 400 to transport the upright battery pack away from the flip mechanism 400. The second transport mechanism 500 may be provided with a structure matching the box 20. When the second transport mechanism 500 transports the box 20 or the upright battery pack, the second transport mechanism 500 can have a better fixing effect on the box 20, thereby improving the stability of the second transport mechanism 500 in the process of transporting the box 20 or the upright battery pack. Thus, the battery module 30 is carried on the object 40, and the box 20 is inverted on the battery module 30, so that the box 20 and the object 40 can provide better protection for the battery module 30. Moreover, the object 40 is carried on the first transport mechanism 100, so that the first transport mechanism 100 can cooperate with the object 40 to stably transport the inverted battery pack, and the box 20 is carried on the second transport mechanism 500, so that the second transport mechanism 500 can cooperate with the box 20 to stably transport the upright battery pack.

[0058] In some embodiments, the battery assembly system 10 further includes a glue coating mechanism 700, which is used to coat the box 20 with adhesive, and the second transport mechanism 500 is used to transport the box 20 coated with adhesive so that the hoisting mechanism 200 can lift the box 20. The adhesive may include but is not limited to instant glue, epoxy resin adhesive, anaerobic glue, hot melt adhesive, pressure sensitive adhesive, latex, etc. In this embodiment, the box 20 may have an inwardly concave receiving groove. In the direction of gravity, when the opening of the receiving groove faces upward, the box 20 can be considered to be upright, and when the opening of the receiving groove faces downward, the box 20 can be considered to be inverted. When it is necessary to coat the box 20 with adhesive, the second transport mechanism 500 transports the upright box 20 to the glue coating mechanism 700, and the glue coating mechanism 700 coats the adhesive on the inner wall of the receiving groove of the box 20. After the glue coating operation is completed, the second transport mechanism 500 can transport the box 20 to a predetermined position, and the hoisting mechanism 200 lifts the box 20 at the predetermined position and flips the box 20 so that the box 20 is inverted on the battery module 30. Thus, the glue coating mechanism 700 coats the box 20 with adhesive, and the box 20 and the battery module 30 can be bonded by the adhesive, thereby improving the stability of the inverted battery pack, improving the firmness of the bonding and fixing of the battery module 30 and the box 20, and ensuring the stability and safety of the battery module 30.

[0059] In some embodiments, the flipping mechanism 400 clamps the load 40 and the box 20 to flip the inverted battery pack into an upright battery pack. The battery module 30 is carried on the load 40, and the box 20 is inverted on the battery module 30. The load 40 and the box 20 can form a clamping structure for the battery module 30 from the two opposite sides of the battery module 30. The flipping mechanism 400 can clamp the load 40 and the box 20 at the same time. Without damaging the battery module 30, the flipping mechanism 400 can stably clamp and flip the battery module 30. Compared with the overall structure of lifting and flipping the battery module 30 and the box 20 by the hoisting mechanism 200, the safety during flipping can be improved.

[0060] Furthermore, the flipping mechanism 400 is used to separate the upright battery pack from the carrier 40, the second transport mechanism 500 carries the box 20 to transport the upright battery pack, and the first transport mechanism 100 is used to transport the carrier 40. After the flipping mechanism 400 clamps the carrier 40 and the box 20 to flip the inverted battery pack into an upright battery pack, the carrier 40 is located above the battery module 30 in the direction of gravity, and the flipping mechanism 400 can further clamp the carrier 40 so that the carrier 40 does not need to be carried on the battery module 30, thereby achieving the purpose of separating the upright battery pack and the carrier 40. After the upright battery pack and the carrier 40 are separated, the second transport mechanism 500 transports the upright battery pack away from the flipping mechanism 400, and the first transport mechanism 100 transports the carrier 40 away from the flipping mechanism 400. For example, the second transport mechanism 500 may first move to the flip mechanism 400 to receive the upright battery pack, and after the second transport mechanism 500 transports the upright battery pack away from the flip mechanism 400, the first transport mechanism 100 moves to the flip mechanism 400 to receive the load 40, so as to transport the load 40 away from the flip mechanism 400. Alternatively, after the flip mechanism 400 separates the upright battery pack from the load 40, the flip mechanism 400 may move the upright battery pack and / or the load 40 to be misaligned in the gravity direction, so that the first transport mechanism 100 and the second transport mechanism 500 may move to the flip mechanism 400 at the same time, and transport the load 40 and the upright battery pack away from the flip mechanism 400 respectively. Thus, after the flip mechanism 400 flips the inverted battery pack into an upright battery pack, the upright battery pack and the load 40 may be directly separated, so as to facilitate the transportation and processing of the upright battery pack and the load 40 respectively, alleviate the obstruction of the load 40 to subsequent operations, and improve the assembly efficiency of the battery module 30.

[0061] Furthermore, the battery assembly system 10 also includes a pressurizing mechanism 600. The second transport mechanism 500 transports the box 20 and the battery module 30 to the pressurizing mechanism 600. The pressurizing mechanism 600 is used to press the box 20 and the battery module 30. After receiving the upright battery pack, the second transport mechanism 500 can transport the upright battery pack to the pressurizing mechanism 600. The pressurizing mechanism 600 presses the battery module 30, which can make the adhesive inside the box 20 more evenly distributed, improve the fixing effect of the battery module 30 and the box 20, and improve the assembly efficiency of the battery module 30. After the second transport mechanism 500 transports the upright battery pack to the pressurizing mechanism 600, the upright battery pack can remain in the second transport mechanism 500. The pressurizing mechanism 600 extends the pressurizing part to press the battery module 30, so as to cooperate with the second transport mechanism 500 to press the box 20 and the battery module 30.

[0062] In some embodiments, at least one of the first transport route 110 of the first transport mechanism 100 and the second transport route 510 of the second transport mechanism 500 is in a ring shape. In this embodiment, the first transport route 110 is in a ring shape, or the second transport route 510 is in a ring shape, or both the first transport route 110 and the second transport route 510 are in a ring shape. The first transport mechanism 100 can travel along the first transport route 110, and the second transport mechanism 500 can travel along the second transport route 510. Compared with the traditional single straight transport route, the occupied area can be more concentrated, alleviating the problem of dispersed logistics distribution and large occupied area.

[0063] Furthermore, the flipping mechanism 400 is located on the first transport route 110 and the second transport route 510. The flipping mechanism 400 can be located on the first transport route 110, and the gluing mechanism 700, the position where the hoisting mechanism 200 lifts the box 20, the flipping mechanism 400 and the pressurizing mechanism 600 can all be located on the second transport route 510. Thus, the flipping mechanism 400 is located on both the first transport route 110 and the second transport route 510, which can facilitate the first transport mechanism 100 to transport the inverted battery pack to the flipping mechanism 400, and facilitate the second transport mechanism 500 to transport the upright battery pack away from the flipping mechanism 400, thereby improving the overall transportation efficiency, and can further alleviate the problem of dispersed logistics distribution and large floor space.

[0064] Furthermore, the second transport route 510 is annular, and the hoisting mechanism 200 flips the box body 20 outside the ring of the second transport route 510. Specifically, after the hoisting mechanism 200 lifts the box body 20, the hoisting mechanism 200 flips the box body 20 outside the ring of the second transport route 510, which can alleviate the risk of interference caused by the second transport route 510 when flipping the box body 20, and then it is convenient to change the positions of the inversion mechanism 300 and the flipping mechanism 400, thereby improving the flexibility of the layout of the battery assembly system 10.

[0065] In some embodiments, the station where the hoisting mechanism 200 lifts the box 20, the station where the inverting mechanism 300 is located, and the station where the first transport mechanism 100 receives the inverted battery pack are in the same direction. The suspension part of the hoisting mechanism 200 can be lifted, turned over, and inverted on the battery module 30 by moving in only one direction, thereby making the layout of the battery assembly system 10 more reasonable and alleviating the problem of scattered logistics distribution and large floor space.

[0066] To summarize, the lifting mechanism 200 inverts the box 20 on the battery module 30 of the inverting mechanism 300 to obtain an inverted battery pack, and transports the inverted battery pack to the flipping mechanism 400 through the inverting mechanism 300 and the first transport mechanism 100 respectively, so that the flipping mechanism 400 flips the inverted battery pack into an upright battery pack. There is no need for the lifting mechanism 200 to lift and flip the overall structure of the battery module 30 and the box 20, which can alleviate the greater safety risks caused by the heavy weight hoisted by the lifting mechanism 200. At the same time, it can also alleviate the risk of large relative displacement between the battery module 30 and the box 20 caused by the unstable hoisting process of the lifting mechanism 200, thereby improving the product yield.

[0067] In order to solve the technical problems existing in the related art, the present application provides a battery assembly method, which can be applied to the battery assembly system 10 of any of the above embodiments. Figure 4 , Figure 4 It is a flowchart of a battery assembly method according to one or more embodiments of the present application, specifically, including the following steps S401 to S403.

[0068] Step S401: In response to the hoisting mechanism, the box is inverted on the battery module to obtain an inverted battery pack, and the inverted battery pack is transported to the first transport mechanism through the inverted mechanism.

[0069] The battery module can be placed on the inverted mechanism in advance. When the battery module needs to be assembled with the box, the box can be transported to a predetermined position first, so that the lifting mechanism can lift the box, and then the box is inverted on the battery module, and the inverted box and the battery module are assembled by the inverted mechanism to obtain an inverted battery pack. The first transport mechanism can stay at a predetermined position before the inverted box is completed. After detecting that the inverted box is completed, the inverted mechanism can be controlled to transport the inverted battery pack to the first transport mechanism.

[0070] Step S402: In response to the inverted battery pack being located on the first transport mechanism, the inverted battery pack is transported to the flipping mechanism via the first transport mechanism.

[0071] The first transport mechanism may be an unmanned guided vehicle, which may include an electromagnetic, optical or visual automatic guidance device, so that the unmanned guided vehicle can travel along a predetermined route or a route planned by itself. After detecting that the first transport mechanism has received the inverted battery pack, the first transport mechanism may transport the inverted battery pack to the flipping mechanism along a predetermined transport path, so that the flipping mechanism can flip the inverted battery pack.

[0072] Step S403: In response to the inverted battery pack being transported to the flipping mechanism, the inverted battery pack is flipped into an upright battery pack by the flipping mechanism.

[0073] When it is detected that the inverted battery pack is transported to the predetermined position of the flipping mechanism, the flipping mechanism can be controlled to clamp the inverted battery pack and flip the inverted battery pack in a certain direction at a specific angle, for example, the inverted battery pack can be flipped 180° to form an upright battery pack. An upright battery pack can be understood as a battery module located above the box in the direction of gravity, and the battery module can be carried by the box.

[0074] Through the above-mentioned implementation mode, the first transport mechanism transports the inverted battery pack to the flipping mechanism, and the flipping mechanism flips the inverted battery pack into an upright battery pack. There is no need to lift and flip the overall structure of the battery module and the box through the lifting mechanism, which can alleviate the greater safety risks caused by the heavy weight lifted by the lifting mechanism. At the same time, it can also alleviate the risk of large relative displacement of the battery module and the box caused by the unstable lifting process of the lifting mechanism, thereby improving the product yield.

[0075] Furthermore, the battery assembly method also includes: in response to the flipping mechanism, flipping the inverted battery pack into an upright battery pack, separating the upright battery pack from the carrier through the flipping mechanism; and transporting the upright battery pack and the carrier from the flipping mechanism respectively.

[0076] The carrier may include but is not limited to a battery tray. The carrier may be used to carry a battery module. In the initial state, the carrier is located on the inverted mechanism, and the battery module may be carried on the carrier. When the lifting mechanism inverts the box body on the battery module to obtain an inverted battery pack, the inverted mechanism transports the carrier and the inverted battery pack to be received by the first transport mechanism, so that the first transport mechanism can transport the carrier and the inverted battery pack to the flip mechanism. The battery module is carried on the carrier, and the box body is inverted on the battery module. The battery module can be clamped from the two opposite sides of the battery module by the carrier and the box body. The flip mechanism can clamp the carrier and the box body at the same time, and can stably clamp and flip the battery module without damaging the battery module. After the flip mechanism clamps the carrier and the box body to flip the inverted battery pack into an upright battery pack, the carrier is located above the battery module in the direction of gravity. The flip mechanism can further clamp the carrier so that the carrier does not need to be carried on the battery module, thereby achieving the purpose of separating the upright battery pack and the carrier. After detecting that the upright battery pack is separated from the load, the load can be transported away from the flipping mechanism by the first transport mechanism, and the upright battery pack can be transported away from the flipping mechanism by the second transport mechanism. Thus, after the flipping mechanism flips the inverted battery pack to the upright battery pack, the upright battery pack and the load can be directly separated, making it easier to transport and process the upright battery pack and the load separately, alleviating the load from interfering with subsequent operations and improving the assembly efficiency of the battery module.

[0077] Furthermore, the steps of transporting the upright battery pack and the load object from the flipping mechanism respectively include: receiving the upright battery pack at the flipping mechanism by the second transport mechanism to transport the upright battery pack away from the flipping mechanism; in response to the upright battery pack being transported away from the flipping mechanism, receiving the load object at the flipping mechanism by the first transport mechanism to transport the load object away from the flipping mechanism.

[0078] The second transport mechanism may first move to the flip mechanism to receive the upright battery pack. After the second transport mechanism transports the upright battery pack away from the flip mechanism, the first transport mechanism then moves to the flip mechanism to receive the load, so as to transport the load away from the flip mechanism, which can make the entire operation layout more reasonable, alleviate the load from interfering with subsequent operations, and improve the assembly efficiency of the battery module. In other embodiments, after the flip mechanism separates the upright battery pack from the load, the flip mechanism may move the upright battery pack and / or the load, so that the upright battery pack and the load are misaligned in the direction of gravity, and then the first transport mechanism and the second transport mechanism may move to the flip mechanism at the same time, and transport the load and the upright battery pack away from the flip mechanism respectively.

[0079] Furthermore, after the step of receiving the upright battery pack at the flipping mechanism by the second transport mechanism to transport the upright battery pack away from the flipping mechanism, the battery assembly method includes: transporting the upright battery pack to the pressurizing mechanism by the second transport mechanism; and pressing the box and the battery module by the pressurizing mechanism. After detecting that the second transport mechanism transports the upright battery pack to the pressurizing mechanism, the pressurizing mechanism presses the battery module, which can make the adhesive inside the box more evenly distributed, improve the fixing effect of the battery module and the box, and improve the assembly efficiency of the battery module. After the second transport mechanism transports the upright battery pack to the pressurizing mechanism, the upright battery pack can remain in the second transport mechanism, and the pressurizing mechanism extends the pressurizing part to press the battery module to cooperate with the second transport mechanism to press the box and the battery module.

[0080] In some embodiments, in response to the lifting mechanism inverting the box on the battery module to obtain an inverted battery pack, the step of transporting the inverted battery pack to the first transport mechanism through the inverted mechanism (step S401) includes: transporting the box to the lifting station through the second transport mechanism; the lifting mechanism lifts the box at the lifting station; flipping the box through the lifting mechanism; inverting the flipped box on the battery module of the inverted mechanism, and assembling the inverted box and the battery module into an inverted battery pack through the inverted mechanism; and transporting the inverted battery pack to the first transport mechanism through the inverted mechanism.

[0081] The lifting station can be any position where the lifting mechanism can lift the box. For example, the lifting mechanism has a suspension part, and the suspension part can move in a specific direction. The lifting station is located at any position on the moving path of the suspension part. The box can be placed upright on the second transport mechanism, and the box is transported to the lifting station by the second transport mechanism. After detecting that the second transport mechanism transports the box to the lifting station, the lifting mechanism can connect with the box at the lifting station and suspend the box. The box is flipped from the upright state to the inverted state by the lifting mechanism, and the box after the flip is inverted on the battery module, and then the inverted box and the battery module are assembled into an inverted battery pack by the inverted mechanism; after detecting that the box is inverted, the inverted mechanism can be controlled to transport the inverted battery pack to the first transport mechanism. Therefore, transporting the box to the lifting station through the second transport mechanism can facilitate the lifting operation of the box by the lifting mechanism, thereby improving the automation of battery assembly. The lifting mechanism only needs to lift and flip the box, which is relative to the lifting mechanism lifting and flipping the overall structure of the battery module and the box. It can alleviate the greater safety risks caused by the heavy weight lifted by the lifting mechanism. At the same time, it can also alleviate the risk of large relative displacement between the battery module and the box caused by the unstable lifting process of the lifting mechanism, thereby improving the product yield.

[0082] Furthermore, the step of transporting the box to the lifting station by the second transport mechanism includes: transporting the box to the gluing mechanism by the second transport mechanism; gluing the box by the gluing mechanism; transporting the glued box to the lifting station by the second transport mechanism. The box may have an inwardly recessed receiving groove, and when the box needs to be coated with adhesive, the second transport mechanism transports the upright box to the gluing mechanism, and the gluing mechanism coats the adhesive on the inner wall of the receiving groove of the box. After completing the gluing operation, the second transport mechanism can transport the box to a predetermined position, and the lifting mechanism lifts the box at the predetermined position, and flips the box so that the box is inverted on the battery module.

[0083] To summarize, the first transport mechanism transports the inverted battery pack to the flipping mechanism, and the flipping mechanism flips the inverted battery pack into an upright battery pack. There is no need to lift and flip the overall structure of the battery module and the box through the lifting mechanism, which can alleviate the greater safety risks caused by the heavy weight lifted by the lifting mechanism. At the same time, it can also alleviate the risk of large relative displacement of the battery module and the box caused by the unstable lifting process of the lifting mechanism, thereby improving the product yield.
