Description

Technical Field

[0001] This invention relates to the field of battery assembly technology, and more specifically to a battery assembly production line. Background Technology

[0002] A storage battery is a rechargeable chemical power source. Its core principle is to achieve the cyclic conversion between chemical energy and electrical energy through a reversible electrochemical reaction. As a core component for efficient energy storage and power supply, storage batteries are widely used in new energy vehicles, energy storage power stations, power tools and consumer electronics. The performance, safety, and production cost of batteries directly depend on the precision and automation level of the manufacturing process. As a key carrier for achieving large-scale and standardized production, the battery assembly line significantly improves production efficiency and product consistency by integrating core processes such as material processing, cell assembly, liquid injection and encapsulation, and formation testing. In modern battery assembly, the cells need to be placed into the casing one by one. If the casing moves, it will cause assembly errors and result in defective products. Currently, it is not possible to quickly fix the battery casing. During assembly, a robotic arm is needed to place the cells into the casing. Therefore, the robotic arm has a large displacement range and the overall work efficiency is low. If dust enters the battery casing during assembly, it will also affect the battery's performance. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a battery assembly production line to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a battery assembly production line, comprising a feeding conveyor belt, a working base plate provided on the side of the feeding conveyor belt, a discharging conveyor belt provided on the side of the working base plate away from the feeding conveyor belt, a cleaning mechanism fixedly connected to the top of the discharging conveyor belt, a lifting mechanism movably connected to the side of the cleaning mechanism, a fixing mechanism fixedly connected to the top of the lifting mechanism, and a battery casing placed on the top of the fixing mechanism; the fixing mechanism includes a supporting fixing box, fixing plates movably connected to both sides inside the fixing box, and movable rods fixedly connected to the sides of the two fixing plates away from each other; a through hole for the movable rods to pass through is provided inside the fixing box, and a spring is provided on the side of the movable rod, the spring being located between the fixing plates and the fixing box.

[0005] Furthermore, a limiting plate is fixedly connected to the side of the moving rod away from the fixed plate, and a gasket is fixedly connected to the side of the limiting plate away from the moving rod. Both the limiting plate and the gasket are located on the outside of the fixed box.

[0006] Furthermore, a baffle plate is fixedly connected to the top of the fixing plate. The sides of the fixing plate and the baffle plate away from the limiting plate are both inclined surfaces, and the inclined surfaces of the fixing plate and the fixing plate are on the same plane. When the fixing plate clamps the battery shell, the side of the baffle plate contacts the inside of the fixing box.

[0007] Furthermore, the lifting mechanism includes a servo motor that can provide power. A reciprocating lead screw is fixedly connected to the top of the servo motor. A cross plate is threadedly connected to the side of the reciprocating lead screw. Limiting rods are provided on the four sides of the cross plate. The two limiting rods closer to the cleaning mechanism do not contact the cross plate, while the two limiting rods farther away from the cleaning mechanism are movably connected to the cross plate. An output gear is fixedly connected to the bottom of the side of the servo motor.

[0008] Furthermore, a connecting plate is fixedly connected to the top of the cross plate, and the top of the connecting plate is fixedly connected to the bottom of the fixed box. When the fixed box moves to the lowest point, the top of the reciprocating screw does not contact the bottom of the fixed box.

[0009] Furthermore, the cleaning mechanism includes a driven gear that meshes with the output gear in the lifting mechanism. The bottom end of the driven gear is provided with a synchronous gear that rotates synchronously with the driven gear. A rotating gear meshes with the side of the synchronous gear. A rotating shaft is fixedly connected to the bottom end of the rotating gear. A blade assembly is fixedly connected to the side of the rotating shaft.

[0010] Furthermore, a gas cylinder is movably connected to the side of the rotating shaft, the side of the gas cylinder is fixedly connected to the top of the working base plate, the blade assembly is located inside the gas cylinder, and an exhaust channel is fixedly connected to the side of the gas cylinder.

[0011] Furthermore, a telescopic tube is fixedly connected to the top end of the gas cylinder, a gas chamber is fixedly connected to the top end of the telescopic tube, a fixed tube is fixedly connected to the top end of the gas chamber, an air inlet pipe is fixedly connected to the top end of the fixed tube, and the side of the gas chamber is fixedly connected to the side of the fixing mechanism.

[0012] The technical effects and advantages of this invention are as follows: This invention comprises a fixed box, a fixed plate, a shielding plate, and a spring. When the robotic arm places the battery casing inside the fixed box, the battery casing moves downward. As the battery casing moves downward, it comes into contact with the fixed plate and the shielding plate, causing the fixed plate and the shielding plate to move outward and compress the spring. When the spring is compressed, it applies a force to the battery casing, thereby fixing the battery casing. When the battery cell is then placed inside the battery casing, the battery casing remains stationary, thus improving the quality. This invention incorporates a servo motor, a reciprocating lead screw, a cross plate, and a connecting plate. When the robotic arm holds the battery cell and places it inside the fixing mechanism, the servo motor starts and drives the reciprocating lead screw to rotate. As the reciprocating lead screw rotates, the cross plate is limited by limit rods around its perimeter, causing the cross plate to move up and down reciprocally. The movement of the cross plate drives the connecting plate to move, which in turn causes the fixing mechanism to move as a whole. When placing the battery cell, the fixing mechanism moves the battery casing upward, reducing the robotic arm's movement distance and thus improving work efficiency. This invention comprises an output gear, a driven gear, a rotating gear, and a blade assembly. When the reciprocating screw rotates, it drives the output gear to rotate. The rotation of the output gear drives the synchronous gear to rotate through the driven gear, which in turn causes the rotating gear to rotate rapidly. The rotation of the rotating gear drives the blade assembly to rotate through the rotating shaft. When the blade assembly rotates, it blows air downwards, which in turn causes the air intake pipe to draw air out. The air intake pipe draws out the dust inside the battery casing, ensuring the quality of the assembled battery. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The battery assembly production line involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figure 1 and Figure 2 The present invention provides a battery assembly production line, including a feeding conveyor belt 1, a working base plate 2 on the side of the feeding conveyor belt 1, a discharging conveyor belt 3 on the side of the working base plate 2 away from the feeding conveyor belt 1, a cleaning mechanism 4 fixedly connected to the top of the discharging conveyor belt 3, a lifting mechanism 5 movably connected to the side of the cleaning mechanism 4, a fixing mechanism 6 fixedly connected to the top of the lifting mechanism 5, and a battery casing 7 placed on the top of the fixing mechanism 6.

[0023] In this embodiment, the feeding conveyor belt 1 feeds the battery casing 7, and the unloading conveyor belt 3 transports the assembled battery casing 7 away. Assembly is performed by a robotic arm to ensure the assembly process proceeds smoothly. The fixing mechanism 6 secures the battery casing 7, the lifting mechanism 5 moves the battery casing 7 up and down, and the cleaning mechanism 4 removes dust from the battery casing 7, improving the quality of the assembled battery casing 7. Furthermore, it should be noted that... Figure 1 The battery casing 7 shown is not placed inside the fixing mechanism 6. When the battery casing 7 is placed inside the fixing mechanism 6, the air intake pipe 411 will suck up the dust inside the battery casing 7.

[0024] Reference Figure 3 and Figure 4The fixing mechanism 6 includes a fixing box 601 for support. Fixing plates 602 are movably connected to both sides inside the fixing box 601. Moving rods 604 are fixedly connected to the sides of the two fixing plates 602 that are far apart from each other. A through hole is provided inside the fixing box 601 for the moving rods 604 to pass through. A spring 605 is provided on the side of the moving rod 604, located between the fixing plates 602 and the fixing box 601. A limit plate 60 is fixedly connected to the side of the moving rod 604 away from the fixing plates 602. 6. A gasket 607 is fixedly connected to the side of the limiting plate 606 away from the moving rod 604. Both the limiting plate 606 and the gasket 607 are located on the outside of the fixed box 601. A baffle plate 603 is fixedly connected to the top of the fixed plate 602. The sides of the fixed plate 602 and the baffle plate 603 away from the limiting plate 606 are both inclined surfaces, and the inclined surfaces of the fixed plate 602 and the fixed plate 603 are on the same plane. When the fixed plate 602 clamps the battery casing 7, the side of the baffle plate 603 contacts the inside of the fixed box 601.

[0025] In this embodiment, when fixing the battery casing 7, the side of the battery casing 7 contacts the baffle plate 603 and the fixing plate 602, causing the fixing plates 602 on both sides to move outward. When the fixing plates 602 move, the spring 605 is compressed. At this time, the elastic force of the spring 605 when compressed is applied to the battery casing 7, thereby fixing the battery casing 7. The moving rod 604 is provided with a limit plate 606 and a gasket 607 on its side. When the battery casing 7 is removed, the spring 605 returns to its original position, causing the fixing plate 602 to move inward, and the gasket 607... It will contact the outside of the fixing box 601 to prevent the moving rod 604 from completely entering the fixing box 601. The fixing plate 602 and the inclined surface of the fixing plate 602 are on the same plane, so that the battery shell 7 contacts the fixing plate 602 and the shielding plate 603, which can stably drive the fixing plate 602 to move. When the fixing plate 602 clamps the battery shell 7, the side of the shielding plate 603 contacts the inside of the fixing box 601 to prevent dust from entering between the fixing box 601, the fixing plate 602 and the shielding plate 603 when installing the battery cell, and ensure that the fixing mechanism 6 is clean enough.

[0026] Reference Figure 5 and Figure 6The lifting mechanism 5 includes a servo motor 501 that provides power. A reciprocating lead screw 502 is fixedly connected to the top of the servo motor 501. A cross plate 503 is threadedly connected to the side of the reciprocating lead screw 502. Limiting rods 505 are provided on the four sides of the cross plate 503. The two limiting rods 505 closer to the cleaning mechanism 4 do not contact the cross plate 503, while the two limiting rods 505 farther away from the cleaning mechanism 4 are movably connected to the cross plate 503. An output gear 506 is fixedly connected to the bottom of the side of the servo motor 501. A connecting plate 504 is fixedly connected to the top of the cross plate 503. The top of the connecting plate 504 is fixedly connected to the bottom of the fixed box 601. When the fixed box 601 moves to the lowest point, the top of the reciprocating lead screw 502 does not contact the bottom of the fixed box 601.

[0027] In this embodiment, the servo motor 501 starts and drives the reciprocating screw 502 to rotate. When the reciprocating screw 502 rotates, the cross plate 503 on its side is limited by the limiting rod 505, thereby causing the cross plate 503 to move upward. When the cross plate 503 moves upward, it drives the connecting plate 504 to move upward. When the connecting plate 504 moves upward, it drives the fixing mechanism 6 and its internal battery casing 7 to move upward as a whole, reducing the movement distance of the robot arm and thus improving work efficiency.

[0028] Reference Figure 2 and Figure 7 The cleaning mechanism 4 includes a driven gear 401 that meshes with the output gear 506 in the lifting mechanism 5. The bottom end of the driven gear 401 is provided with a synchronous gear 402 that rotates synchronously with the driven gear 401. A rotating gear 403 meshes with the side of the synchronous gear 402. A rotating shaft 404 is fixedly connected to the bottom end of the rotating gear 403. A blade assembly 407 is fixedly connected to the side of the rotating shaft 404. A gas cylinder 405 is movably connected to the side of the rotating shaft 404. The side of the gas cylinder 405 is fixedly connected to the top end of the working base plate 2. The blade assembly 407 is located inside the gas cylinder 405. An exhaust channel 406 is fixedly connected to the side of the gas cylinder 405. A telescopic tube 408 is fixedly connected to the top end of the gas cylinder 405. A gas chamber 409 is fixedly connected to the top end of the telescopic tube 408. A fixed tube 410 is fixedly connected to the top end of the gas chamber 409. An air inlet tube 411 is fixedly connected to the top end of the fixed tube 410. The side of the gas chamber 409 is fixedly connected to the side of the fixing mechanism 6.

[0029] In this embodiment, when the driven gear 401 rotates, it drives the synchronous gear 402 to rotate via the limiting rod 505. When the synchronous gear 402 rotates, it drives the rotating gear 403 to rotate faster. The 403 drives the rotating shaft 404 and the blade group 407 to rotate, while the blade group 407 blows air downwards. At this time, the gas in the gas cylinder 405 will be blown downwards into the exhaust channel 406. The telescopic tube 408 is in a negative pressure state. Therefore, the gas chamber 409, the fixed tube 410 and the air inlet tube 411 connected to the telescopic tube 408 will all be in a negative pressure state. The air inlet tube 411 will draw air inwards, thereby removing the dust from the battery casing 7 and improving the assembly quality.

[0030] The working principle of this invention is as follows: During assembly, the feeding conveyor belt 1 delivers the battery casing 7 to the side of the working substrate 2. At this time, the robot arm picks up the battery casing 7 and places it in the fixed box 601. When the robot arm places the battery casing 7 downward, the side of the battery casing 7 contacts the baffle plate 603 and the fixing plate 602, thereby causing the fixing plates 602 on both sides to move outward. When the fixing plates 602 move, the spring 605 is compressed. At this time, the elastic force of the spring 605 when it is compressed is applied to the battery casing 7, thereby fixing the battery casing 7. After the battery casing 7 is fixed, the robotic arm holds the battery cell and places it inside the battery casing 7. When the robotic arm holds the battery cell downward, the servo motor 501 starts and drives the reciprocating screw 502 to rotate. When the reciprocating screw 502 rotates, the cross plate 503 on its side is limited by the limit rod 505, so that the cross plate 503 moves upward. When the cross plate 503 moves upward, it drives the connecting plate 504 to move upward. When the connecting plate 504 moves upward, it drives the fixing mechanism 6 and the battery casing 7 inside it to move upward as a whole. After the battery casing 7 is sent to the top, the battery casing 7 stops. At this time, the robotic arm moving downward places the battery cell inside the battery casing 7. The robotic arm moves up and holds the next battery cell. The servo motor 501 controls the reciprocating screw 502 to rotate again. At this time, the fixing mechanism 6 drives the battery casing 7 to move downward. Therefore, the robotic arm does not need to move a long distance to completely separate from the battery casing 7. During assembly, when the reciprocating screw 502 rotates, it drives the output gear 506 to rotate. When the output gear 506 rotates, it drives the driven gear 401 to rotate. When the driven gear 401 rotates, it drives the synchronous gear 402 to rotate through the limit rod 505. When the synchronous gear 402 rotates, it drives the rotating gear 403 to rotate faster. When the rotating gear 403 rotates, it drives the rotating shaft 404 to rotate. When the rotating shaft 404 rotates, it drives the blade assembly 407 to rotate. When the blade assembly 407 rotates, it blows air downwards. At this time, the gas in the gas cylinder 405 will be blown downwards into the exhaust channel 406. The telescopic pipe 408 is in a negative pressure state. Therefore, the gas chamber 409, the fixed pipe 410 and the air inlet pipe 411 connected to the telescopic pipe 408 will all be in a negative pressure state. The air inlet pipe 411 will draw air inward, thereby removing the dust from the battery casing 7, reducing the dust content in the battery casing 7 and ensuring the quality of the battery after assembly.

[0031] In conclusion, the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
