Description

Technical Field

[0001] The present invention relates to the technical field of battery manufacturing, and in particular to a flipping system, a method for using the flipping system, and a method for producing a battery using the flipping system. Background Art

[0002] During the battery production process, there is a flipping process that requires the battery to be flipped over in order to facilitate subsequent inspection of its appearance. Due to the heavy weight of the battery, there is a risk of the battery falling during the flipping process of the flipping system in the prior art. Summary of the invention

[0003] The main purpose of the present invention is to provide a flipping system, aiming to improve the risk of batteries falling during the flipping process.

[0004] To achieve the above-mentioned purpose, the flipping system proposed in the present invention includes a bracket, a driving assembly and a control module. The driving assembly includes a lifting mechanism, a rotating component and a clamping assembly. The lifting mechanism is connected to the bracket in a transmission manner to drive the bracket to lift and lower. The rotating component is installed on the bracket to drive the battery to flip. The clamping assembly includes a main clamping component and a holding component, and the main clamping component and the holding component are independent of each other and are both connected to the rotating component. The control module is connected to the lifting mechanism, the rotating component and the clamping assembly by signal, and controls the main clamping component to clamp the two opposite sides of the battery, and the holding component to clamp the bottom and top surfaces of the battery.

[0005] The technical solution of the present invention is to connect the lifting mechanism with the bracket through transmission, install the rotating assembly on the bracket, and connect the main clamping assembly and the holding assembly in the clamping assembly to the rotating assembly, so that the lifting mechanism can drive the bracket, the rotating assembly, and the clamping assembly to rise or fall synchronously, so that when the clamping assembly clamps the battery, the lifting mechanism drives the battery to rise to a certain height, which is conducive to providing a space for avoiding the battery from turning over; when the lifting mechanism drives the battery to descend, the battery can be placed in the initial position. By arranging the main clamping assembly and the holding assembly independently from each other, it is conducive to the main clamping assembly to rise a certain distance after clamping the battery, so as to provide a movement space for the bottom of the battery after the holding assembly moves, reduce the interference between the holding assembly and the battery when the holding assembly moves, and also reduce the risk of interference between the holding assembly and the battery when the main clamping assembly clamps the battery. In addition, the holding assembly is used to clamp the bottom and top surfaces of the battery, so that the battery is not easy to fall during the process of rising, turning and falling.

[0006] In one embodiment, the holding assembly includes a bottom supporting mechanism and a top clamping mechanism. The bottom supporting mechanism includes a first clamping cylinder and a holding plate. The first clamping cylinder is installed on the rotating assembly and is in signal connection with the control module. The holding plate is connected to the output shaft of the first clamping cylinder and is used to hold the bottom of the battery. The top clamping mechanism is connected to the holding plate and is used to clamp the top of the battery. With such a setting, the movement stroke when the top clamping mechanism presses the top of the battery can be reduced. In addition, the interference between it and the main clamping assembly can be reduced, making it smoother when the main clamping assembly clamps the battery.

[0007] In one embodiment, two bottom supporting mechanisms are provided oppositely, and the two bottom supporting mechanisms respectively hold opposite sides of the bottom surface of the battery. With such a setting, the bottom surface of the battery can be more balanced after being held, reducing the risk of the battery falling.

[0008] In one embodiment, the holding plate includes a vertical plate and a bottom plate. The vertical plate is connected to the first clamping cylinder and is perpendicular to the output shaft of the first clamping cylinder. The top clamping mechanism is connected to the vertical plate. The bottom plate is connected to the vertical plate at an angle and is used to hold the bottom of the battery. With such a setting, on the one hand, the installation space for the holding assembly installed on the rotating assembly is reduced, and on the other hand, the top clamping mechanism can move horizontally along with the vertical plate, thereby reducing the movement stroke or the occupied space when the top clamping mechanism clamps the top of the battery.

[0009] In one embodiment, the top clamping mechanism includes a second clamping cylinder and a pressing plate. The second clamping cylinder is connected to the holding plate and is in signal connection with the control module, and the output shaft of the second clamping cylinder extends in the up and down direction. The pressing plate is connected to the output shaft of the second clamping cylinder and is used to press the top of the battery. With such a setting, when the output shaft of the second cylinder moves, it will drive the pressing plate to move up and down, facilitating the pressing plate to press the top of the battery. In addition, by connecting the second clamping cylinder to the holding plate, the second clamping cylinder and the pressing plate connected to the second clamping cylinder can move synchronously with the holding plate, thereby reducing the movement stroke of the second clamping cylinder driving the pressing plate alone, or the setting size of the pressing plate can be reduced.

[0010] In one embodiment, the extending direction of the output shaft of the first clamping cylinder and the clamping direction of the main clamping assembly are both in the horizontal direction, and the extending direction of the output shaft of the first clamping cylinder is perpendicular to the clamping direction of the main clamping assembly. With such a setting, the first clamping cylinder and the main clamping assembly can clamp different sides of the battery, further improving the clamping stability of the battery and reducing the risk of the battery falling.

[0011] In one embodiment, the rotating assembly includes a motor, a driving shaft, a driven shaft, and a connecting frame. The motor is mounted on the bracket and is in signal connection with the control module. The driving shaft is rotatably connected to the bracket and is in transmission connection with the motor. The driven shaft is rotatably connected to the bracket and is coaxially arranged with the driving shaft. The driving shaft and the driven shaft are respectively connected to opposite sides of the connecting frame, and the clamping assembly is connected to the connecting frame. With such an arrangement, the driving shaft, the driven shaft, and the connecting frame form an integral whole. Then, when the driving shaft rotates, it can drive the driven shaft and the connecting frame to rotate synchronously, improving the rotation consistency of the rotating assembly and reducing the risk of the driven shaft downtime.

[0012] The present invention also proposes a usage method based on the above-mentioned flipping system, and this usage method includes:

[0013] Lowering and clamping step: The lifting mechanism lowers a preset distance, and the main clamping assembly clamps the battery.

[0014] First rising step: The lifting mechanism rises a first distance.

[0015] Holding step: The holding assembly clamps the bottom surface and the top surface of the battery.

[0016] Second rising and flipping step: The lifting mechanism rises a second distance, and the rotating assembly drives the clamping assembly and the battery to rotate a predetermined angle.

[0017] In the technical solution of the present invention, by controlling the lowering of the lifting mechanism, it is convenient for the lifting mechanism to drive the main clamping assembly to lower and face the side of the battery, so as to facilitate the main clamping assembly to clamp the battery. Then, after the battery is stably clamped, it can be lifted under the drive of the lifting mechanism. When the main clamping assembly extends and clamps the battery, by controlling the control module to make the lifting mechanism rise a first distance, it provides an avoidance space for the holding assembly to hold the bottom surface of the battery. Thus, it is convenient for a part of the holding assembly to extend into the gap between the bottom surface of the battery and the tray, so as to control a part of the holding assembly to be located below the battery and have a good limiting effect on the downward movement of the battery. By making the holding assembly clamp the bottom surface and the top surface of the battery, the battery can be limited in both the up and down directions, thus providing a guarantee for the battery after flipping and reducing the risk of it falling after flipping. Finally, by the control module continuing to control the lifting mechanism to rise a second distance, at this time, the rising height of the battery is already relatively high, and the distance between the battery and the tray is large enough, so as to reduce the risk of interference between the battery and the tray when the battery is flipped. After the preparatory work and the reserved space are reserved, when the rotating assembly drives the clamping assembly and the battery to rotate a predetermined angle, the flipping of the battery core is made smoother.

[0018] In one embodiment, the holding assembly includes a bottom supporting mechanism and a top surface clamping mechanism. The bottom supporting mechanism includes a first clamping cylinder and a holding plate, the first clamping cylinder is installed on the rotating assembly, and the holding plate is connected to the output shaft of the first clamping cylinder and is used to hold the bottom of the battery. The top surface clamping mechanism is connected to the holding plate and is used to clamp the top surface of the battery. The holding steps include:

[0019] The first clamping cylinder drives the pocket plate to extend so that the pocket plate holds the bottom of the battery;

[0020] The top surface clamping mechanism clamps the top surface of the battery.

[0021] Such an arrangement can provide a good supporting effect on the battery in the first place, and timely reduce the risk of the battery falling. In addition, when the first clamping cylinder drives the pocket plate to extend, the top surface clamping mechanism will also extend synchronously with the pocket plate, so as to be closer to the battery clamped by the main clamping assembly, thereby reducing the clamping path of the top surface clamping mechanism when clamping the battery.

[0022] In one embodiment, the pocket plate includes a vertical plate and a bottom plate. The vertical plate is connected to the first clamping cylinder, and the top surface clamping mechanism is connected to the vertical plate. The bottom plate is connected to the vertical plate at an angle and is used to hold the bottom of the battery. The above-mentioned first clamping cylinder drives the pocket plate to extend so that the pocket plate holds the bottom of the battery further includes:

[0023] The first clamping cylinder drives the vertical plate to move in a direction perpendicular to the vertical plate.

[0024] The vertical plate drives the bottom plate to move in a direction parallel to the bottom surface of the battery, so that at least a portion of the bottom plate can be arranged opposite to the bottom of the battery.

[0025] By driving the bottom plate to move in a direction parallel to the bottom surface of the battery, the bottom plate can be extended under the action of the vertical plate and the first clamping cylinder to extend to the bottom of the battery 1, thereby holding the bottom of the battery.

[0026] In one embodiment, the top surface clamping mechanism includes a second clamping cylinder and a pressure plate. The second clamping cylinder is connected to the pocket plate, and the output shaft of the second clamping cylinder extends in the up-down direction. The pressure plate is connected to the output shaft of the second clamping cylinder and is used to clamp the top surface of the battery. The steps of clamping the top surface of the battery by the top surface clamping mechanism include:

[0027] The output shaft of the second clamping cylinder retracts and drives the pressing plate down;

[0028] After the driving platen is lowered to the third distance, the second clamping cylinder is closed.

[0029] With such a setting, the second clamping cylinder drives the pressing plate to move towards the top surface of the battery until the top surface of the battery is pressed tightly. At this time, the effect of the top surface clamping mechanism pressing the top surface of the battery is achieved. After the pressing plate is driven to descend by a third distance, the pressing plate can press the battery tightly. At this time, the output shaft of the second clamping cylinder also reaches the position, so the second clamping cylinder is closed to reduce the risk of damaging the battery due to the continuous downward movement of the pressing plate.

[0030] In one embodiment, after the above-mentioned secondary ascending and flipping steps, the following steps are further included:

[0031] The lifting mechanism descends by a second distance, and the holding assembly is controlled to return to the initial position;

[0032] The lifting mechanism descends by a first distance, and the battery is placed back on the tray.

[0033] With such a setting, the risk of interference between the holding assembly and the tray when the holding assembly withdraws can be reduced, so that the holding assembly can disengage from the battery more smoothly, and the battery can be placed back on the tray and flow into the next working station.

[0034] In one embodiment, after the above-mentioned step of the lifting mechanism descending by a first distance and placing the battery back on the tray, the following steps are further included:

[0035] The main clamping assembly releases the battery.

[0036] The lifting mechanism ascends by a preset distance to wait for the battery to move to the next working station.

[0037] When the main clamping assembly releases the battery, the clamping cylinder and the battery are no longer linked. Thus, when the lifting mechanism ascends by a preset distance, the clamping assembly can be driven to ascend without causing the battery to ascend again, thereby providing a good avoidance space for the battery to move to the next working station. In addition, with such a setting, a good avoidance space is also provided for the next battery to move smoothly under the flipping system.

[0038] In one embodiment, before the above-mentioned step of descending and clamping, the following step is further included:

[0039] Detect whether the battery reaches the flipping position.

[0040] When it is detected that the battery reaches the flipping position, the step of descending and clamping is executed.

[0041] By executing the above-mentioned step of descending and clamping only when it is detected that the battery reaches the flipping position, the operation of the flipping system for descending and clamping can be controlled more precisely, and the control precision of the flipping system during the flipping of the battery is improved.

[0042] The present invention also proposes a production method for a battery, including:

[0043] Produce a battery and place the battery on a tray located on a conveyor line;

[0044] Clamp the battery using the clamping assembly in the above-mentioned flipping system, and drive the battery to rise using the lifting mechanism in the above-mentioned flipping system;

[0045] Drive the battery and the clamping assembly to flip using the rotating component in the above-mentioned flipping system.

[0046] The technical solution of the present invention flips the battery through the above-mentioned flipping system, making the battery relatively stable during the flipping process, reducing the risk of its dropping, and thus improving the production quality of the battery.

[0070] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydraulic, thermal, wind, and solar power stations, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing. Therefore, the production and manufacturing process of batteries increasingly requires automation to reduce the labor intensity of workers and the labor cost.

[0071] The production process of batteries includes the production of batteries. During the battery production process, a flipping system is required to flip the batteries for processes such as film pasting, testing, or cleaning the bottom of the batteries. However, the existing flipping systems usually include a rotary driving device and a clamping assembly. The clamping assembly only includes two relatively arranged jaws, and at least one jaw is connected to the rotary driving device to drive the clamped battery to flip together under the drive of the rotary driving device. But since the clamping assembly in the existing technology only includes two relatively arranged jaws, and there is no device to prevent the battery from falling at the positions near the top and bottom of the battery, there is a high risk of the battery falling during the flipping process of the battery, which may lead to battery damage.

[0072] To solve this technical problem, the present invention proposes a flipping system for flipping the battery 1.

[0073] In the embodiments of the present invention, please refer to Figures 1 to 4 , the flipping system includes a bracket 100, a driving assembly and a control module (not shown). The driving assembly includes a lifting mechanism 200, a rotating assembly 300 and a clamping assembly 400. The lifting mechanism 200 is connected to the bracket 100 in a transmission manner to drive the bracket 100 to rise and fall. The rotating assembly 300 is installed on the bracket 100 to drive the battery 1 to flip. The clamping assembly 400 includes a main clamping assembly 410 and a holding assembly 420, and the main clamping assembly 410 and the holding assembly 420 are independent of each other and are both connected to the rotating assembly 300. The control module is connected to the lifting mechanism 200, the rotating assembly 300 and the clamping assembly 400 by signal, and controls the main clamping assembly 410 to clamp the two opposite sides of the battery 1, and the holding assembly 420 to clamp the bottom and top surfaces of the battery 1.

[0074] The bracket 100 is a component for supporting the rotating assembly 300, the battery 1, and the clamping assembly 400. The bracket 100 may be in a frame shape, so as to provide a space for the battery 1 to escape when it is turned over. The bracket 100 may be in a rectangular frame shape or an arc frame shape. In order to improve the support strength of the bracket 100, the bracket 100 may be made of metal material.

[0075] The lifting mechanism 200 refers to a mechanism that can drive the bracket 100 to rise and fall, which can be a linear motor 340, a cylinder or a gear rack assembly, etc. It can be understood that the flipping system also includes a mounting plate for mounting the lifting mechanism 200, or the lifting mechanism 200 is directly mounted on the housing of the flipping system. By connecting the lifting mechanism 200 to the bracket 100 through transmission to drive the bracket 100 to rise and fall, the rotating assembly 300, the clamping assembly 400 and the battery 1 connected to the bracket 100 can be driven by the bracket 100 to rise or fall to a certain height, which is conducive to lifting the battery 1 to provide a flipping avoidance space for the battery 1 to flip, or to lower the battery 1 to the tray 2 of the conveying platform below.

[0076] The rotating assembly 300 is one of the important components of the flipping system. The rotating assembly 300 refers to a component that can drive the battery 1 and the clamping assembly 400 to rotate. The rotating assembly 300 may include components such as a drive motor 340 and a rotating shaft. The rotating shaft rotates to drive the clamping assembly 400 to rotate, and then the battery 1 clamped by the clamping assembly 400 is driven to flip through the clamping assembly 400. The angle at which the rotating assembly 300 drives the clamping assembly 400 and the battery 1 to flip can be 45°, 60°, 90° or 180°, etc. It should be noted that the angle at which the rotating assembly 300 drives the battery 1 to flip is not specifically limited, and it can be set according to actual usage. For example, the flipping angle can be limited by a limit structure, or the flipping angle can be controlled by using a servo motor 340.

[0077] The clamping assembly 400 refers to a mechanism for clamping the side of the battery 1. The clamping assembly 400 can be a manipulator or a clamping cylinder, etc. The clamping assembly 400 is to prevent the battery 1 from falling easily when it is flipped. The clamping assembly 400 includes a main clamping component 410 and a holding component 420. Among them, the main clamping component 410 refers to a component that can mainly clamp the battery 1, such as a cylinder, a screw-nut assembly, etc. When the battery 1 is clamped only by the main clamping component 410, when the lifting mechanism 200 drives the bracket 100, the rotating component 300 on the bracket 100 and the clamping assembly 400 to rise, the battery 1 can also rise synchronously with the clamping assembly 400. The holding component 420 refers to a component that holds the bottom and top of the battery 1, and it plays an auxiliary supporting role in clamping the battery 1 by the main clamping component 410, thereby further reducing the risk of the battery 1 falling.

[0078] The control module refers to a control unit for controlling each mechanism or component. It is used to receive signals and transmit signals, so as to control each mechanism or component to perform corresponding actions. The control module is signal-connected to the lifting mechanism 200, so the control module can control the lifting mechanism 200 to lift and lower. The control module is signal-connected to the rotating component 300, then it can control the rotating component 300 to rotate, and then drive the clamping assembly 400 connected to the rotating component 300 and the battery 1 clamped by the clamping assembly 400 to rotate. The control module is signal-connected to the clamping assembly 400, then it can control the clamping assembly 400 to clamp or release the battery 1. For example, when it is detected that the battery 1 reaches the flipping position, the control module controls the lifting mechanism 200 to lower. When the lifting mechanism 200 descends to a predetermined position, the clamping assembly 400 is opposite to the side of the battery 1. The control module is signal-connected to the clamping assembly 400, so as to control the main clamping component 410 in the clamping assembly 400 to clamp two opposite sides of the battery 1. After the main clamping component 410 clamps two opposite sides of the battery 1, the control module receives a signal and gives a signal to the lifting mechanism 200 to control the lifting mechanism 200 to rise a first distance. After the lifting mechanism 200 rises the first distance, the control module controls the holding component 420 to clamp the bottom and top surfaces of the battery 1; then, the control module controls the lifting mechanism 200 to rise a second distance; finally, the control module controls the rotating component 300 to rotate a predetermined angle, so as to achieve the effect of automatically flipping the battery 1.

[0079] It should be noted that when the battery 1 arrives at the flipping station, its initial state is that the surface of the battery 1 with the pole faces upward, so the surface of the battery 1 with the pole is defined as the top surface of the battery 1, and the surface of the battery 1 opposite to the surface with the pole is defined as the bottom surface, and the other surfaces of the battery 1 excluding the top surface and the bottom surface are all the side surfaces of the battery 1. When the clamping assembly 400 clamps the side surface of the battery 1, it can refer to clamping the left and right opposite sides of the battery 1, or it can refer to clamping the front and back opposite sides of the battery 1.

[0080] The technical solution of the present invention sets the main clamping assembly 410 and the holding assembly 420 independently from each other, so that the main clamping assembly 410 will not drive the holding assembly 420 to work in conjunction when it moves, so that after the main clamping assembly 410 clamps the side of the battery 1, it can first be driven to rise a certain distance through the lifting mechanism 200, so that the battery 1 leaves the tray 2 and forms an escape space between the tray 2 and the bottom of the battery 1 for the holding assembly 420 to insert into the tray 2, and then the holding assembly 420 is driven separately to clamp the bottom and / or top surface of the battery 1, thereby reducing the risk of interference between the holding assembly 420 and the battery 1 when the main clamping assembly 410 clamps the battery 1. Among them, at least two main clamping assemblies 410 can be arranged opposite to each other, so that two opposite surfaces of the battery 1 can be clamped, thereby improving the stability of clamping.

[0081] The technical solution of the present invention is to connect the lifting mechanism 200 with the bracket 100 through transmission, the rotating component 300 is installed on the bracket 100, and the main clamping component 410 and the holding component 420 in the clamping assembly 400 are both connected to the rotating component 300, so that the lifting mechanism 200 can drive the bracket 100, the rotating component 300, and the clamping assembly 400 to rise or fall synchronously, so that when the clamping assembly 400 clamps the battery 1, the lifting mechanism 200 drives the battery 1 to rise to a certain height, which is conducive to providing avoidance space for the battery 1 to flip over; when the lifting mechanism 200 drives the battery 1 to fall, it can place the battery 1 to the initial position. By arranging the main clamping assembly 410 and the holding assembly 420 independently of each other, it is beneficial for the main clamping assembly 410 to rise a certain distance after clamping the battery 1, thereby providing movement space for the holding assembly 420 to hold the bottom of the battery 1 after it is actuated, reducing the interference between the holding assembly 420 and the battery 1 during movement, and also reducing the risk of interference between the holding assembly 420 and the battery 1 when the main clamping assembly 410 clamps the battery 1.

[0082] In an example, please refer to Figures 1 to 4The holding assembly 420 includes a bottom supporting mechanism 421 and a top surface clamping mechanism 422. The bottom supporting mechanism 421 includes a first clamping cylinder 4211 and a scoop plate 4212. The first clamping cylinder 4211 is installed on the rotating assembly 300 and is connected to the control module signal. The scoop plate 4212 is connected to the output shaft of the first clamping cylinder 4211 and is used to hold the bottom of the battery 1. The top surface clamping mechanism 422 is connected to the scoop plate 4212 and is used to clamp the top surface of the battery 1.

[0083] The bottom supporting mechanism 421 refers to a mechanism for holding the bottom surface of the battery 1 and for clamping the bottom surface of the battery 1. The bottom supporting mechanism 421 includes a first clamping cylinder 4211 and a pocket plate 4212, wherein the first clamping cylinder 4211 serves as a power source for the bottom supporting mechanism 421, and is used to provide power for the pocket plate 4212 to hold the bottom surface of the battery 1. The length extension direction of the output shaft of the first clamping cylinder 4211 can be in the horizontal direction or in any direction that is at an angle to the vertical direction, as long as it can achieve an avoidance space for the battery 1 to enter the flipping system to be clamped by the main clamping assembly 410 when it is in the initial position, and can be brought to the pocket plate 4212 to hold the bottom of the battery 1 after it is extended. Alternatively, the first clamping cylinder 4211 can be slidably arranged on the rotating assembly 300 in the horizontal direction, and has an output shaft extending in the vertical direction, so that when there is no need to hold the bottom of the battery 1, that is, when the battery 1 is only held by the main clamping assembly 410, the first clamping cylinder 4211 can be retracted relative to the rotating assembly 300 to a position that can avoid the battery 1, so that the main clamping assembly 410 can hold the battery 1; then, by making the first clamping cylinder 4211 slide relative to the rotating assembly 300 and slide to the bottom of the battery 1, the output shaft of the first clamping cylinder 4211 drives the pocket plate 4212 to extend upward to clamp the bottom surface of the battery 1. The pocket plate 4212 refers to a component that can at least hold the bottom surface of the battery 1. The pocket plate 4212 can be a flat plate structure, which can move to the bottom of the battery 1 under the driving action of the first clamping cylinder 4211, so as to have a better limiting effect on the bottom of the battery 1 and reduce the risk of the battery 1 falling. Alternatively, the pocket plate 4212 can be an L-shaped plate structure, which, under the driving action of the first clamping cylinder 4211, can make one of the plate surfaces be located at the bottom of the battery 1 to limit the bottom surface of the battery 1 and reduce the risk of the battery 1 falling, and the other surface can be against the side of the battery 1, thereby further improving the clamping effect of the battery 1.

[0084] The top surface clamping mechanism 422 is a mechanism for holding and clamping the top surface of the battery 1, and its purpose is to reduce the risk of the battery 1 falling after turning over. The structure of the top surface clamping mechanism 422 can be similar to that of the bottom supporting mechanism 421, and will not be described in detail here.

[0085] In the technical solution of the present invention, the top clamping mechanism 422 is connected to the pocket plate 4212 of the bottom supporting mechanism 421 above, making the entire pocket holding assembly 420 an integral whole, thus facilitating installation on the rotating assembly 300 and reducing the installation space on the rotating assembly 300. And by connecting the top clamping mechanism 422 to the pocket plate 4212 of the bottom supporting mechanism 421, when the first clamping cylinder 4211 in the bottom supporting mechanism 421 drives the pocket plate 4212 to move, the pocket plate 4212 can synchronously drive the top clamping mechanism 422 to move together, so that the top clamping mechanism 422 is closer to the battery 1, reducing the movement stroke of the top clamping mechanism 422, simplifying the movement stroke of the top clamping mechanism 422 or reducing the volume of the top clamping mechanism 422. For example, when the output shaft of the first clamping cylinder 4211 in the bottom supporting mechanism 421 moves horizontally to drive the pocket plate 4212 to extend horizontally and hold the bottom of the battery 1, the top clamping mechanism 422 can move along with the pocket plate 4212 in the direction close to the battery 1. The top clamping mechanism 422 can include a driving cylinder and a top plate, and the output shaft of the driving cylinder can extend upward, and the top plate is connected to the output shaft of the driving cylinder. Or, the top clamping mechanism 422 can be a snap plate connected to the pocket plate 4212, that is, a plate body structure provided with snaps. During the upward movement of the snap plate along with the pocket plate 4212, the snap plate also rises. When the pocket plate 4212 rises in place, the snaps of the snap plate are simultaneously pressed against the top surface of the battery 1. In addition, with such a setting, the interference phenomenon with the main clamping assembly 410 can also be reduced, making it smoother when the main clamping assembly 410 clamps the battery 1.

[0086] In one example, at least two bottom supporting mechanisms 421 are provided opposite to each other to respectively hold the opposite two side edges of the bottom surface of the battery 1.

[0087] Two opposite bottom supporting mechanisms 421 can be used to hold the front side edge and the rear side edge of the bottom surface of the battery 1; or, two opposite bottom supporting mechanisms 421 can be used to hold the left side edge and the right side edge of the bottom surface of the battery 1.

[0088] By providing at least two bottom supporting mechanisms 421 opposite to each other to respectively hold the opposite two side edges of the bottom surface of the battery 1, the bottom surface of the battery 1 can be held more balanced, reducing the risk of the battery 1 falling.

[0089] Based on the solution of providing two bottom supporting mechanisms 421 opposite to each other, at least two top clamping mechanisms 422 can also be provided. A top clamping mechanism 422 is provided on the pocket plate 4212 of each bottom supporting mechanism 421, so as to also press the opposite two side edges of the top surface of the battery 1 to reduce the risk of the battery 1 falling after being flipped.

[0090] In one embodiment, please refer to Figure 3 and Figure 4 , the pocket plate 4212 includes a vertical plate 4212a and a bottom plate 4212b. The vertical plate 4212a is connected to the first clamping cylinder 4211, and the top surface clamping mechanism 422 is connected to the vertical plate 4212a. The bottom plate 4212b is connected to the vertical plate 4212a at an angle and is used to hold the bottom of the battery 1.

[0091] The vertical plate 4212a refers to a plate structure whose largest plate surface is a vertical plane. The vertical plate 4212a can be made of metal or polymer material. In order to facilitate a better stable effect when connecting the top surface clamping mechanism 422 to the vertical plate 4212a, the vertical plate 4212a is preferably made of metal material.

[0092] The bottom plate 4212b is a plate located on one side of the bottom surface of the battery 1 and is used to hold the bottom of the battery 1. The material of the bottom plate 4212b can be metal or polymer material. The bottom plate 4212b can be integrally formed with the vertical plate 4212a to improve the overall connection strength of the pocket plate 4212. Or the bottom plate 4212b and the vertical plate 4212a can be fixedly connected by means of screw connection, bonding or welding. The bottom plate 4212b can be a flat plate or a curved plate, etc., as long as it can achieve the effect of holding the bottom of the battery 1.

[0093] By connecting the vertical plate 4212a to the output shaft of the first clamping cylinder 4211, the first clamping cylinder 4211 can be arranged opposite to the side surface of the battery 1. Thus, when the lifting mechanism 200 drives the rotating assembly 300 and the clamping assembly 400 to descend to clamp the battery 1, the first clamping cylinder 4211 can provide an avoidance space for the battery 1. When the main clamping assembly 410 clamps the battery 1 and rises a certain distance under the action of the lifting mechanism 200, the output shaft of the first clamping cylinder 4211 then extends to drive the vertical plate 4212a and the bottom plate 4212b to move laterally together, so that the vertical plate 4212a can clamp the side surface of the battery 1, and at the same time the bottom plate 4212b is located below the bottom surface of the battery 1 to hold the bottom surface of the battery 1, reducing the risk of the battery 1 falling. With such a setting, only by the action of the output shaft of the first clamping cylinder 4211 extending, the bottom of the battery 1 can be held and the clamping effect on the battery 1 can be improved at the same time.

[0094] By connecting the top surface clamping mechanism 422 to the vertical plate 4212a, on the one hand, the installation space for installing the pocket holding assembly 420 on the rotating assembly 300 is reduced, and on the other hand, the top surface clamping mechanism 422 can move horizontally with the vertical plate 4212a, thus reducing the movement stroke or the occupied space when the top surface clamping mechanism 422 clamps the top surface of the battery 1.

[0095] In one example, please refer to Figure 1 and Figure 2 , the top clamping mechanism 422 includes a second clamping cylinder 4221 and a pressing plate 4222. The second clamping cylinder 4221 is connected to the hopper plate 4212 and is in signal connection with the control module, and the output shaft of the second clamping cylinder 4221 extends in the vertical direction. The pressing plate 4222 is connected to the output shaft of the second clamping cylinder 4221 and is used to press the top surface of the battery 1.

[0096] The second clamping cylinder 4221 refers to a power source for providing power for the pressing plate 4222 to abut against the top surface of the battery 1.

[0097] The pressing plate 4222 refers to a plate structure for pressing the top surface of the battery 1.

[0098] By extending the output shaft of the second clamping cylinder 4221 in the vertical direction and connecting the pressing plate 4222 to the output shaft of the second clamping cylinder 4221 in a transmission manner, when the output shaft of the second cylinder moves, it will drive the pressing plate 4222 to move up and down, so as to facilitate the pressing plate 4222 to press the top surface of the battery 1. In addition, by connecting the second clamping cylinder 4221 to the hopper plate 4212, the second clamping cylinder 4221 and the pressing plate 4222 connected to the second clamping cylinder 4221 can move synchronously with the hopper plate 4212, thereby reducing the movement stroke of the second clamping cylinder 4221 driving the pressing plate 4222 alone, or the set size of the pressing plate 4222 can be reduced.

[0099] For example, when the hopper plate 4212 includes the above-mentioned vertical plate 4212a and bottom plate 4212b, the second clamping cylinder 4221 can be connected to the vertical plate 4212a. Thus, when the vertical plate 4212a moves in the horizontal direction to approach the side surface of the battery 1, the second clamping cylinder 4221 also moves in the horizontal direction and approaches the side surface of the battery 1, so that the size of the pressing plate 4222 connected to the output shaft of the second clamping cylinder 4221 can be set to be a little smaller to achieve the effect that the pressing plate 4222 can press the top surface of the battery 1. Or, when the hopper plate 4212 includes a bottom plate 4212b, the size of the bottom plate 4212b can be set to be larger, and the second clamping cylinder 4221 can be arranged on the bottom plate 4212b and used to avoid the battery 1.

[0100] In one embodiment, please refer to Figure 1 and Figure 2 , the extending direction of the output shaft of the first clamping cylinder 4211 and the clamping direction of the main clamping assembly 410 are both in the horizontal direction, and the extending direction of the output shaft of the first clamping cylinder 4211 is perpendicular to the clamping direction of the main clamping assembly 410.

[0101] The extending direction of the output shaft of the first clamping cylinder 4211 refers to the extending direction of the output shaft of the first clamping cylinder 4211 during operation.

[0102] The clamping direction of the main clamping assembly 410 refers to the direction of the clamping force exerted on the battery 1 by the main clamping assembly 410 during operation.

[0103] By setting both the extending direction of the output shaft of the first clamping cylinder 4211 and the clamping direction of the main clamping assembly 410 to the horizontal direction, when in the initial state, both the main clamping assembly 410 and the first clamping cylinder 4211 can avoid the battery 1, enabling the battery 1 to be located within the space enclosed by the main clamping assembly 410 and the first clamping cylinder 4211, thus facilitating the simultaneous clamping of the surface of the battery 1 by the main clamping assembly 410 and the first clamping cylinder 4211. Setting the extending direction of the output shaft of the first clamping cylinder 4211 perpendicular to the clamping direction of the main clamping assembly 410 means that, for example, when the extending direction of the output shaft of the first clamping cylinder 4211 is forward or backward, the clamping direction of the main clamping assembly 410 is left or right; or for example, when the extending direction of the output shaft of the first clamping cylinder 4211 is left or right, the clamping direction of the main clamping assembly 410 is forward or backward.

[0104] By setting the extending direction of the output shaft of the first clamping cylinder 4211 perpendicular to the clamping direction of the main clamping assembly 410, the first clamping cylinder 4211 and the main clamping assembly 410 can clamp different sides of the battery 1, thereby further improving the clamping stability of the battery 1 and reducing the risk of the battery 1 falling.

[0105] In one example, please refer to Figure 1 and Figure 3 , the rotating assembly 300 includes a driving shaft 310, a driven shaft 320, and a connecting frame 330. The driving shaft 310 is rotatably connected to the bracket 100. The driven shaft 320 is rotatably connected to the bracket 100 and is coaxially arranged with the driving shaft 310. The driving shaft 310 and the driven shaft 320 are respectively connected to opposite sides of the connecting frame 330, and the clamping assembly 400 is connected to the connecting frame 330.

[0106] The driving shaft 310 refers to the shaft that plays a driving role.

[0107] The driven shaft 320 refers to the shaft that rotates under the driving action of the driving shaft 310.

[0108] The connecting frame 330 refers to a frame structure used to connect the driving shaft 310 and the driven shaft 320. By setting the connecting member between the driving shaft 310 and the driven shaft 320 as a frame structure, when the clamping assembly 400 is connected to the connecting frame 330, a clamping avoidance space can be provided for the battery 1 clamped by the clamping assembly 400.

[0109] By respectively connecting the driving shaft 310 and the driven shaft 320 to opposite sides of the connecting frame 330 and coaxially arranging the driving shaft 310 and the driven shaft 320, the driving shaft 310, the driven shaft 320 and the connecting frame 330 form an integral body. Then, when the driving shaft 310 rotates, it can drive the driven shaft 320 and the connecting frame 330 to rotate synchronously, improving the rotation consistency of the rotating assembly 300 and reducing the risk of the driven shaft 320 crashing.

[0110] To reduce manual operation, as Figure 1 or Figure 3 shown, the rotating assembly 300 further includes a motor 340. The motor 340 is installed on the bracket 100 and is signal-connected to the control module. The driving shaft 310 is in transmission connection with the motor 340 to drive the driving shaft 310 to rotate.

[0111] The motor 340 refers to a power source that can provide power after being energized to change the motion trajectory of the component in transmission connection with it. The motor 340 is usually used as a rotating power source to provide the power of rotation. By signal-connecting the motor 340 to the control module, the control module can control the rotation of the motor 340 to achieve the effect of jointly rotating the driving shaft 310, the driven shaft 320, the connecting frame 330, the clamping assembly 400 and the battery 1 clamped by the clamping assembly 400 by a preset angle.

[0112] By installing the motor 340 on the bracket 100 and in transmission connection with the driving shaft 310, when the driving shaft 310 rotates, it can be driven by the motor 340, thus reducing the situation of manually driving the driving shaft 310 to rotate and improving the degree of automation.

[0113] The present invention also proposes a usage method of the flipping system. Please refer to Figure 1 and Figure 5 to flip the battery 1. The usage method of this flipping system is based on the above flipping system. The specific structure of this flipping system refers to the above embodiments. Since the usage method of this flipping system adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments and will not be elaborated one by one here. Among them, the usage method of this flipping system includes:

[0114] S10: Lowering and clamping step: The lifting mechanism 200 lowers a preset distance, and the main clamping component 410 clamps the battery 1.

[0115] It is understandable that in order to provide an avoidance space when the battery 1 is conveyed to the flipping position, the initial position of the flipping system should be above the battery 1. In order to flip the battery 1, it is necessary for the flipping mechanism to first descend or for the battery 1 to ascend so that the battery 1 is clamped by the clamping assembly 400 of the flipping mechanism.

[0116] In the technical solution of the present invention, by controlling the lifting mechanism 200 to descend a preset distance, the lifting mechanism 200 drives the main clamping assembly 410 to descend a preset distance, so that the main clamping assembly 410 descends to a position opposite to the side surface of the battery 1, facilitating the main clamping assembly 410 to clamp the battery 1. Then, the main clamping assembly 410 clamps the battery 1, achieving the effect of the initial clamping of the battery 1 by the flipping system. At this time, it is convenient to lift and lower the battery 1 together by the main clamping assembly 410. It should be noted that the value of the preset distance is the difference between the initial position of the lifting mechanism 200 and the position where it descends to enable the main clamping assembly 410 to clamp the side surface of the battery 1.

[0117] S20: First rising step: The lifting mechanism 200 rises a first distance.

[0118] By making the lifting mechanism 200 rise a first distance, it is to reserve a holding space for the holding assembly 420 to hold the bottom surface of the battery 1, thereby reducing the risk of interference between the bottom clamping assembly and the tray 2 or the battery 1 during operation. The first distance can be set larger or smaller, but it should be such that the first distance is sufficient to provide enough holding space for the bottom clamping assembly to hold the bottom surface of the battery 1.

[0119] S30: Holding step: The holding assembly 420 clamps the bottom and top surfaces of the battery 1.

[0120] After the lifting mechanism 200 rises a first distance, the battery 1 is separated from the tray 2, creating a certain gap between the battery 1 and the tray 2. This facilitates the holding assembly 420 to at least partially extend into the gap between the bottom surface of the battery 1 and the tray 2 after it operates, providing a limiting effect on the bottom surface of the battery 1 and reducing the risk of the battery 1 falling when it rises again.

[0121] In addition, the holding assembly 420 can also clamp the top surface of the battery 1, providing protection for the battery 1 when the battery 1 is flipped and reducing the risk of the battery 1 falling after flipping.

[0122] S40: Second rising and flipping step: The lifting mechanism 200 rises a second distance, and the rotating assembly 300 drives the clamping assembly 400 and the battery 1 to rotate a predetermined angle.

[0123] After the various surfaces of the battery 1 are jointly clamped by the main clamping assembly 410 and the holding assembly 420, the lifting mechanism 200 continues to lift the battery 1, thereby providing a necessary avoidance space for the battery 1 during flipping and reducing the risk of interference between the battery 1 and the tray 2 when the battery 1 flips. The predetermined angle during the flipping of the battery 1 can be determined according to actual needs. For example, it can be 45°, 60°, 90°, or 180°, etc. To achieve an automated effect, the rotation assembly 300 may include a servo motor 340, so that the battery 1 can be driven by the servo motor 340 to flip a predetermined angle each time.

[0124] In the technical solution of the present invention, by controlling the lowering of the lifting mechanism 200, it is convenient for the lifting mechanism 200 to drive the main clamping assembly 410 to lower and face the side of the battery 1, so as to facilitate the main clamping assembly 410 to clamp the battery 1, and then the battery 1 can be stably clamped and lifted under the drive of the lifting mechanism 200. After the main clamping assembly 410 clamps the battery 1, by controlling the lifting mechanism 200 to rise by a first distance, an avoidance space is provided for the holding assembly 420 to hold the bottom surface of the battery 1, so that a part of the holding assembly 420 can extend into the gap between the bottom surface of the battery 1 and the tray 2, so that a part of the holding assembly 420 is located below the battery 1 and has a good limiting effect on the downward movement of the battery 1. By controlling the holding assembly 420 to clamp the bottom surface and the top surface of the battery 1 through the control module, the battery 1 can be limited in both the up and down directions, thereby providing a guarantee for the battery 1 after flipping and reducing the risk of it falling after flipping. Finally, by controlling the lifting mechanism 200 to rise by a second distance through the control module, at this time, the rising height of the battery 1 is already relatively high, and the distance between the battery 1 and the tray 2 is large enough, so that the risk of interference between the battery 1 and the tray 2 during flipping can be reduced. After the preparatory work and the reserved space are reserved, when the control module controls the rotation assembly 300 to drive the clamping assembly 400 and the battery 1 to rotate a predetermined angle, the flipping of the battery core is made smoother.

[0125] In one example, please refer to Figures 1 to 6 , the holding assembly 420 includes a bottom supporting mechanism 421 and a top clamping mechanism 422. The bottom supporting mechanism 421 includes a first clamping cylinder 4211 and a holding plate 4212. The first clamping cylinder 4211 is installed on the rotation assembly 300, and the holding plate 4212 is connected to the output shaft of the first clamping cylinder 4211 and is used to hold the bottom of the battery 1. The top clamping mechanism 422 is connected to the holding plate 4212 and is used to clamp the top surface of the battery 1. The above S30: holding step further includes:

[0126] S31: The first clamping cylinder 4211 drives the holding plate 4212 to extend so that the holding plate 4212 holds the bottom of the battery 1.

[0127] First, the first clamping cylinder 4211 drives the pocket plate 4212 to extend to limit the bottom of the battery 1, so that the battery 1 can be well supported at the first time and the risk of the battery 1 falling can be reduced in time.

[0128] S32 : The top surface clamping mechanism 422 clamps the top surface of the battery 1 .

[0129] Based on the above scheme of connecting the top surface clamping mechanism 422 to the pocket plate 4212, when the first clamping cylinder 4211 drives the pocket plate 4212 to extend, the top surface clamping mechanism 422 will also be extended synchronously with the pocket plate 4212, so as to be closer to the battery 1 clamped by the main clamping assembly 410, thereby reducing the clamping path of the top surface clamping mechanism 422 when clamping the battery 1. Among them, the top surface clamping mechanism 422 may include a driving member and a pressing member, the driving member is provided on the pocket plate 4212, and the pressing member is connected to the driving member and used to press the top surface of the battery 1. Alternatively, the top surface clamping mechanism 422 may be a buckle plate connected to the pocket plate 4212, that is, a plate structure with buckles, and the buckle plate moves upward with the pocket plate 4212, and the buckle plate also rises. When the pocket plate 4212 rises to its position, the buckle of the buckle plate is pressed against the top surface of the battery 1 at the same time.

[0130] In an example, please refer to Figures 1 to 7 , the pocket plate 4212 includes a vertical plate 4212a and a bottom plate 4212b. The vertical plate 4212a is connected to the first clamping cylinder 4211, and the top surface clamping mechanism 422 is connected to the vertical plate 4212a. The bottom plate 4212b is connected to the vertical plate 4212a at an angle and is used to hold the bottom of the battery 1. The above S31: the first clamping cylinder 4211 drives the pocket plate 4212 to extend so that the pocket plate 4212 holds the bottom of the battery 1 further includes:

[0131] S311: The first clamping cylinder 4211 drives the vertical plate 4212a to move in a direction perpendicular to the vertical plate 4212a.

[0132] When the battery 1 is driven to rise or fall, its movement direction is parallel to the plate surface of the vertical plate 4212. By driving the vertical plate 4212a to move in a direction perpendicular to the vertical plate 4212a by the first clamping cylinder 4211, the risk of interference by the first clamping cylinder 4211 when the battery 1 enters the gap between the two main clamping assemblies 410 due to the first clamping cylinder 4211 being located at the bottom of the battery 1 can be reduced.

[0133] S312 : The vertical plate 4212 a drives the bottom plate 4212 b to move in a direction parallel to the bottom surface of the battery 1 , so that at least a portion of the bottom plate 4212 b can be disposed opposite to the bottom of the battery 1 .

[0134] By driving the vertical plate 4212 to move the bottom plate 4212b in a direction parallel to the bottom surface of the battery 1, the bottom plate 4212b can be extended under the action of the vertical plate 4212 and the first clamping cylinder 4211 to extend below the battery 1, so as to be able to hold the bottom of the battery 1. Or, with such a setting, the bottom plate 4212b can also be retracted under the action of the vertical plate 4212 and the first clamping cylinder 4211, so as to provide a clearance space when the battery 1 enters the gap between the two opposite main clamping assemblies 410, or provide a clearance space when the flipping system places the battery 1 back on the tray 2.

[0135] In one example, please refer to Figure 1 , Figure 2 and Figure 8 , the top surface clamping mechanism 422 includes a second clamping cylinder 4221 and a pressing plate 4222. The second clamping cylinder 4221 is connected to the pocket plate 4212, and the output shaft of the second clamping cylinder 4221 extends in the up and down direction. The pressing plate 4222 is connected to the output shaft of the second clamping cylinder 4221 and is used to press the top surface of the battery 1. The above S32: clamping the top surface of the battery 1 by the top surface clamping mechanism 422, and its steps further include:

[0136] S321: The output shaft of the second clamping cylinder 4221 retracts and drives the pressing plate 4222 to descend.

[0137] Since the pocket plate 4212 is used to hold the bottom of the battery 1, the pocket plate 4212 is usually not set higher than the top surface of the battery 1. Therefore, the second clamping cylinder 4221 provided on the pocket plate 4212 is usually not set higher than the top surface of the battery 1 either. When the output shaft of the second clamping cylinder 4221 is in the extended state, the pressing plate 4222 connected to the output shaft needs to have a certain distance from the top surface of the battery 1. Otherwise, when the output shaft of the second clamping cylinder 4221 retracts, the top surface of the battery 1 and the pressing plate 4222 will interfere with each other. Therefore, after the second clamping cylinder 4221 is provided on the pocket plate 4212, the extended state of the output shaft of the second clamping cylinder 4221 is its initial state. On this basis, by retracting the output shaft of the second clamping cylinder 4221, the second clamping cylinder 4221 drives the pressing plate 4222 to move towards the top surface of the battery 1 until the top surface of the battery 1 is pressed, and at this time, the effect of the top surface clamping mechanism 422 pressing the top surface of the battery 1 is achieved.

[0138] S322: After driving the pressing plate 4222 to descend to a third distance, the second clamping cylinder 4221 is closed.

[0139] The third distance can be preset, that is, obtained by setting the movement stroke of the output shaft of the second clamping cylinder 4221, and the movement stroke of the output shaft of the second clamping cylinder 4221 is the third distance. The setting of the third distance is based on the distance between the pressing plate 4222 from the initial position to the position where it can just abut against the top surface of the battery 1. Thus, after driving the pressing plate 4222 to descend to the third distance, the pressing plate 4222 can press the battery 1 tightly. At this time, the output shaft of the second clamping cylinder 4221 also runs in place. Therefore, the second clamping cylinder 4221 is closed to reduce the risk of damaging the battery 1 due to the continuous downward movement of the pressing plate 4222.

[0140] In one example, please refer to Figure 1 , Figure 3 and Fig. 9 , S40: Secondary rising and flipping step: The lifting mechanism 200 rises by the second distance, and the rotating assembly 300 drives the clamping assembly 400 and the battery 1 to rotate by a predetermined angle. After this step, it further includes:

[0141] S50: The lifting mechanism 200 descends by the second distance, and controls the holding assembly 420 to return to the initial position.

[0142] After the rotating assembly 300 drives the clamping assembly 400 and the battery 1 to rotate by a predetermined angle, the flipping system also needs to place the flipped battery 1 back on the tray 2. By making the lifting mechanism 200 descend by the second distance, the bracket 100, the rotating assembly 300, the clamping assembly 400, and the battery 1 all descend by the second distance. At this time, the position is the same as the position where the battery 1 is about to be clamped by the holding assembly 420, and the distance from this position to the tray 2 is not too large. Therefore, releasing the holding assembly 420 here can hardly cause the risk of the battery 1 falling; and by releasing the holding assembly 420 here, the risk of interference between the holding assembly 420 and the tray 2 during withdrawal can be reduced, enabling the holding assembly 420 to disengage from the battery 1 more smoothly.

[0143] S60: The lifting mechanism 200 descends by the first distance, and places the battery 1 back on the tray 2.

[0144] When the holding assembly 420 is disengaged from the bearing effect on the battery 1, the holding assembly 420 returns to the initial position, which provides an avoidance space for the battery 1 to be placed back on the tray 2. Furthermore, by making the lifting mechanism 200 descend by the first distance again, the battery 1 can be placed back on the tray 2 and flow into the next working station.

[0145] Furthermore, as Fig.10 shown, after the above S60: The lifting mechanism 200 descends by the first distance and places the battery 1 back on the tray 2, it further includes:

[0146] S70: The main clamping assembly 410 releases the battery 1.

[0147] S80: The lifting mechanism 200 rises by a preset distance to wait for the battery 1 to move to the next station.

[0148] After the flipping system places the battery 1 on the tray 2, it is necessary to release the battery 1 to provide an avoidance space for the battery 1 and enable the battery 1 to enter the next station. By loosening the main clamping assembly 410 from the battery 1, the clamping cylinder 410 and the battery 1 are no longer linked. Thus, when the lifting mechanism 200 rises by a preset distance, it can drive the clamping assembly 400 to rise without causing the battery 1 to rise again, thereby providing a good avoidance space for the battery 1 to move to the next station. Additionally, with this arrangement, it also provides a good avoidance space for the next battery 1 to smoothly move under the flipping system.

[0149] In an example, as Fig.11 shown, before the above-mentioned S10: Lower and clamp step, it further includes:

[0150] S01: Detect whether the battery 1 reaches the flipping position.

[0151] The battery 1 is usually placed on the tray 2, and the tray 2 is placed on the conveyor line to be conveyed from the previous station of the flipping position to the flipping position. A device for detecting in place is provided at each flipping position, or a device for detecting the battery 1 in place is provided on the flipping system. When the detection device detects that the battery 1 reaches the flipping position, the flipping system starts to flip the battery 1. The station corresponding to the lower part of the flipping system is the flipping position, that is, the station for flipping the battery 1. During detection, a photoelectric sensor or other in-place sensing device can be set. When the photoelectric sensor or other in-place sensing device senses that the battery 1 reaches the flipping position, the photoelectric sensor or other in-place sensing device transmits a signal to the lifting mechanism 200, and thus the lifting mechanism 200 descends by a preset distance.

[0152] S02: When it is detected that the battery 1 reaches the flipping position, execute the step of lowering and clamping.

[0153] By executing the above-mentioned step of lowering and clamping only when it is detected that the battery 1 reaches the flipping position, the operation of the flipping system for lowering and clamping can be controlled more precisely, improving the control accuracy of the flipping system when flipping the battery 1.

[0154] The present invention also proposes a production method for the battery 1. Please refer to Figure 1 and Fig.12, the usage method is based on the above-mentioned flipping system, and the specific structure of the flipping system refers to the above-mentioned embodiments. Since the production method of the battery 1 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here. Among them, the production method of the battery 1 includes:

[0155] S101: Produce the battery 1 and place the battery 1 on the tray 2 located on the conveyor line.

[0156] The conveyor line is a flow line connecting each station for producing the battery 1. In order to reduce the wear on the battery 1, the battery 1 is usually placed on the tray 2, and then the tray 2 and the battery 1 on the tray 2 are placed on the conveyor line for transportation together. By placing the produced battery 1 on the tray 2 of the conveyor line, the battery 1 can be moved to each production station along with the conveyor line.

[0157] S102: Clamp the battery 1 by the clamping assembly 400 in the above-mentioned flipping system, and drive the battery 1 to rise by the lifting mechanism 200 in the above-mentioned flipping system.

[0158] Clamp the battery 1 by the clamping assembly 400 in the above-mentioned flipping system, and drive the battery 1 to rise by the lifting mechanism 200 in the above-mentioned flipping system, so as to have enough flipping space when the battery 1 is flipped and reduce the interference with the conveyor line and the tray 2.

[0159] S103: Drive the battery 1 and the clamping assembly 200 to flip by the rotating assembly 300 in the above-mentioned flipping system.

[0160] Flip the battery 1 through the above-mentioned flipping system, so that the battery 1 is relatively stable during the flipping process, reducing the risk of its dropping, and then improving the production quality of the battery 1.

[0161] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
