Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, specifically to a lithium battery electrolyte filling and directional capping device. Background Technology

[0002] A battery is a cup, tank, or other container or composite container containing an electrolyte solution and metal electrodes to generate an electric current. It is a device that converts chemical energy into electrical energy and has positive and negative electrodes. With the advancement of technology, the term "battery" has come to refer to small devices that can generate electrical energy, such as solar cells. The main performance parameters of a battery are electromotive force, capacity, specific energy, and resistance. Batteries are also divided into primary batteries and secondary batteries. Secondary batteries, also known as rechargeable batteries or storage batteries, are a type of battery that can be reused after being discharged by recharging to activate the active materials. Their working principle is based on the reversibility of chemical reactions. The main types include lead-acid batteries, lithium-ion batteries, and nickel-metal hydride batteries. Secondary batteries use an electrolyte filled inside as a dielectric to achieve battery recycling.

[0003] After the secondary battery is filled with electrolyte and allowed to stand, it needs to be capped. During the capping operation, glue is dripped into the inside of the cap, and then the cap is flipped over and placed on top of the battery and pressed firmly. Generally, the cap is placed manually or the entire cap placement tray is flipped over. Manual operation is inefficient, and flipping the entire cap placement tray can cause the cap to fall out of the tray. Therefore, this does not meet the current requirements. To address this, we propose a lithium battery electrolyte filling and directional capping device. Summary of the Invention

[0004] The purpose of this invention is to provide a lithium battery liquid injection directional capping device to solve the problems mentioned in the background art, which are generally caused by manual placement of caps or by flipping the entire cap placement tray. Manual operation is inefficient, and when the entire cap placement tray is flipped, the caps are prone to falling out of the cap placement tray.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lithium battery electrolyte injection and directional capping device, comprising an electrolyte injection machine, a settling machine, a dispensing machine, a battery cap conveyor, and a cap flipping and docking module. The battery cap conveyor includes a base, and the upper surface of the base is provided with an automatic feeder, a material tray, a transverse movement module, a longitudinal movement module, a cap suction robotic arm, and a placement tray conveyor belt. A battery cap placement tray is placed on the upper surface of the transverse movement module and the placement tray conveyor belt. A placement tray gripping module is slidably provided on the outer side of the longitudinal movement module. The cap flipping docking module includes a sliding seat, a guide rail, a moving robotic arm, and a battery cap flipping module. The guide rail is fixed to the front of the dispensing machine and parallel to the front edge of the dispensing machine. The sliding seat is slidably installed on the outside of the guide rail, and the moving robotic arm is fixed to the upper surface of the sliding seat. The battery cap flipping module includes a connecting block, which is fixed to the execution end of the mobile robotic arm. A double-headed electric telescopic rod is fixed through the middle of the connecting block. Both ends of the double-headed electric telescopic rod are fixed with clamps. The inner side of the clamps is provided with a flipping groove. A flipping block is rotatably provided inside the flipping groove. A positioning plug is fixed outside the flipping block. A flipping motor is fixed outside the clamps. The output shaft end of the flipping motor passes through the clamps and is fixed to the flipping block. The two clamps clamp and transport the battery cap placement tray, and flip the battery cap placement tray through the flipping motor, the flipping block and the positioning plug.

[0006] Preferably, a balance guide rod and a threaded rod are fixed to the outer side of the clamping plate, and a movable frame is slidably provided on the outer side of the threaded rod and the balance guide rod. Multiple pressing electric telescopic rods are fixed to the top and bottom surfaces of the movable frame, and a movable block is also slidably provided on the outer side of the threaded rod. The movable block is fixed to the movable frame.

[0007] Preferably, the movable block includes a housing, an actuator motor, a movable sleeve, and two meshing transmission gears. The movable sleeve is disposed on the outside of the threaded rod and is driven by the threaded rod through the thread. One of the transmission gears is fixed on the outside of the movable sleeve, and the other transmission gear is fixed to the output end of the actuator motor. The actuator motor is fixed inside the housing, and a heat dissipation hole is provided on one side of the housing.

[0008] Preferably, the end of the clamp that connects to the double-headed electric telescopic rod is provided with a buffer groove. The presence of the buffer groove ensures that the battery cover placement tray will not come into contact with the clamp when it is flipped, thereby ensuring that the flipping of the battery cover placement tray is not interfered with.

[0009] Preferably, the battery cap placement tray includes a tray body, with positioning grooves on both sides of the tray body. The positioning plug is slidably inserted into the inner side of the positioning groove. The surface of the tray body is provided with a plurality of placement grooves distributed in a rectangular array, and the placement grooves are used to place the battery cap.

[0010] Preferably, two sets of mutually symmetrically distributed limiting electric telescopic rods and anti-detachment electric telescopic rods are fixed on the inner side of the placement groove. The movable end of the limiting electric telescopic rod is close to the center of the placement groove and the end is fixed with a limiting plate. Both ends of the limiting plate are bent at ninety degrees toward the middle of the placement groove.

[0011] Preferably, the length of the top end of the limiting plate is less than the length of the bottom end of the limiting plate, and a sliding groove is provided through the middle of the limiting plate.

[0012] Preferably, the movable end of the anti-detachment electric telescopic rod passes through the inside of the sliding groove, and a pressure plate is fixed to this end of the anti-detachment electric telescopic rod, the size of which is smaller than the size of the sliding groove.

[0013] Preferably, the surface of the sliding groove is bonded with an anti-slip pad, and the surface of the anti-slip pad is provided with a plurality of anti-slip grooves linearly arrayed along the length direction of the anti-slip pad.

[0014] Preferably, the material tray is located below the discharge port of the automatic feeder, the cap suction robot arm is fixed above the material tray by the frame, the tray gripping module includes a slider seat, the slider seat slides linearly outside the longitudinal movement module, a lifting cylinder is fixed outside the slider seat, and a clamp is provided at the bottom of the lifting cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a double-headed electric telescopic rod to control the clamping plate to fit against the side of the battery cap placement tray. A flipping motor drives the flipping block and the insertion-inside to rotate, thereby flipping the battery cap placement tray and the internal battery cap. A mobile robotic arm then docks the flipped battery cap with the battery injected with electrolyte, and presses it in place using the electric telescopic rod. This achieves automatic docking and capping of the battery cap, improving work efficiency and reducing the workload of workers. 2. The present invention uses limiting plates with different lengths at both ends to support and limit the battery cap placed inside the placement slot, so as to prevent the battery cap from falling out of the battery cap placement tray when the battery cap placement tray is flipped, and at the same time ensure that the battery cap will not fall out of the bottom of the placement slot when it is placed inside the placement slot. 3. In this invention, after the battery cap placement tray is flipped and the limiting plate is separated from the battery cap, the battery cap is clamped by the pressure plate and anti-slip pad, which prevents the battery cap from falling off during the process of being flipped and transferred by the moving robotic arm to dock with the battery. 4. This invention utilizes a moving block to control the movement of the moving frame, thereby aligning the pressing electric telescopic rod with the battery cap. The pressing electric telescopic rod presses the flipped battery cap downwards, achieving automatic docking and clamping of the battery cap. Simultaneously, the moving frame drives the pressing electric telescopic rod to move, ensuring that the flipping action of the battery cap placement tray is not affected. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] like Figures 1 to 3 As shown, a lithium battery electrolyte injection and directional capping device includes an electrolyte injector, a settling machine 1, a dispensing machine 2, a battery cap conveyor 3, and a cap flipping and docking module.

[0020] The battery cap conveyor 3 includes a base 301. The upper surface of the base 301 is provided with an automatic feeder 303, a material tray 304, a transverse movement module 305, a longitudinal movement module 302, a cap-collecting robotic arm 309, and a placement tray conveyor belt 308. A battery cap placement tray 306 is placed on the upper surface of the transverse movement module 305 and the placement tray conveyor belt 308. A placement tray gripping module 307 is slidably provided on the outer side of the longitudinal movement module 302.

[0021] The material tray 304 is located below the discharge port of the automatic feeder 303. The cap suction robot arm 309 is fixed above the material tray 304 by the frame. The placement tray gripping module 307 includes a slider seat. The slider seat slides linearly on the outside of the longitudinal movement module 302. A lifting cylinder is fixed on the outside of the slider seat. A clamp is provided at the bottom of the lifting cylinder. The clamp is used to transport and transfer the battery cap placement tray 306 on the surface of the transverse movement module 305 and the placement tray conveyor belt 308. The lifting cylinder adjusts the height of the clamp to separate the battery cap placement tray 306 from the contacting parts.

[0022] The lateral movement module 305 includes an end support block, a drive screw, a movable slide, a guide rod, and a drive motor. The two ends of the drive screw are connected to the end support block through ball bearings. The end of the guide rod is fixed to the end support block. The guide rod and the drive screw pass through the movable slide, and the guide screw and the movable slide are driven by a thread. The output shaft of the drive motor is connected to one end of the guide screw through a fixing pin. The battery cap placement tray 306 is placed on the upper surface of the movable slide.

[0023] The cap flipping docking module includes a sliding seat, a guide rail, a moving robotic arm, and a battery cap flipping module 4. The guide rail is fixed to the front of the dispensing machine 2 and parallel to the front edge of the dispensing machine 2. The sliding seat is slidably installed on the outside of the guide rail, and the moving robotic arm is fixed to the upper surface of the sliding seat.

[0024] like Figures 4 to 7 As shown, the battery cap placement tray 306 includes a tray body 3061. Positioning grooves 3062 are provided on both sides of the tray body 3061. Positioning plugs 412 are slidably inserted into the inner side of the positioning grooves 3062. Multiple rectangular array placement grooves 3063 are distributed through the surface of the tray body 3061. The placement grooves 3063 are used to place battery caps. Two sets of symmetrically distributed limiting electric telescopic rods 3064 and anti-detachment electric telescopic rods 3066 are fixed to the inner side of the placement grooves 3063. The movable end of the limiting electric telescopic rod 3064 is close to the center of the placement groove 3063 and a limiting plate 3065 is fixed to the end. Both ends of the limiting plate 3065 are bent at a 90-degree angle towards the middle of the placement groove 3063. The limiting plate 3065 supports and limits the battery cap placed inside the placement groove 3063, preventing the battery cap from falling out of the battery cap placement tray 306 when it is flipped.

[0025] The top length of the limiting plate 3065 is less than the bottom length of the limiting plate 3065. A sliding groove 3067 is provided through the middle of the limiting plate 3065. The different lengths of the two ends of the limiting plate 3065 can ensure that when the battery cover is placed inside the placement groove 3063, the bottom end of the limiting plate 3065 supports the battery cover, while the top end of the limiting plate 3065 will not affect the placement of the battery cover.

[0026] The movable end of the anti-detachment electric telescopic rod 3066 passes through the inside of the sliding groove 3067, and a pressure plate 3068 is fixed to this end of the anti-detachment electric telescopic rod 3066. The size of the pressure plate 3068 is smaller than the size of the sliding groove 3067. An anti-slip pad 3069 is bonded to the surface of the sliding groove 3067. The surface of the anti-slip pad 3069 is provided with multiple anti-slip grooves arranged in a linear array along the length of the anti-slip pad 3069. After the battery cap placement tray 306 is flipped and the limiting plate 3065 is separated from the battery cap, the battery cap is clamped by the pressure plate 3068 and the anti-slip pad 3069 to prevent the battery cap from falling off.

[0027] like Figure 4 and Figure 5 As shown, the battery cap flipping module 4 includes a connecting block 401, which is fixed to the execution end of the mobile robotic arm. A double-headed electric telescopic rod 402 is fixed through the middle of the connecting block 401. Both ends of the double-headed electric telescopic rod 402 are fixed with clamping plates 403. A flipping groove 413 is provided on the inner side of the clamping plate 403. A flipping block 411 is rotatably provided on the inner side of the flipping groove 413. A positioning plug-in block 412 is fixed on the outer side of the flipping block 411. A flipping motor 409 is fixed on the outer side of the clamping plate 403. The output shaft end of the flipping motor 409 passes through the clamping plate 403 and is fixed to the flipping block 411. The two clamping plates 403 clamp and transport the battery cap placement tray 306. The battery cap placement tray 306 is flipped by the flipping motor 409, the flipping block 411 and the positioning plug-in block 412, so as to flip the cap placed inside the battery cap placement tray 306. Then, the mobile robotic arm connects the cap inside the flipped battery cap placement tray 306 with the battery.

[0028] A balance guide rod 408 and a threaded rod 407 are fixed to the outer side of the clamping plate 403. A movable frame 410 is slidably provided on the outer side of the threaded rod 407 and the balance guide rod 408. Multiple pressing electric telescopic rods 406 are fixed on the top and bottom surfaces of the movable frame 410. A movable block 405 is also slidably provided on the outer side of the threaded rod 407. The movable block 405 is fixed to the movable frame 410. The movable block 405 includes a housing, an actuator motor, a movable sleeve, and two meshing transmission gears. The movable sleeve is disposed on the outer side of the threaded rod 407 and is driven by the threaded rod 407 through the thread. One of the transmission gears is fixed on the outer side of the movable sleeve, and the other transmission gear is fixed to the output end of the actuator motor. The actuator motor is fixed inside the housing, and a heat dissipation hole is provided on one side of the housing. The movable block 405 is used to control the movement of the movable frame 410 to align the pressing electric telescopic rod 406 with the battery cap, or to move the pressing electric telescopic rod 406 away from the top of the battery cap placement tray 306, thereby ensuring that the flipping of the pressing electric telescopic rod 406 is not affected.

[0029] The end of the clamping plate 403 connected to the double-headed electric telescopic rod 402 is provided with a buffer groove 404. The presence of the buffer groove 404 ensures that the battery cover placement tray 306 will not come into contact with the clamping plate 403 when it is flipped, thereby ensuring that the flipping of the battery cover placement tray 306 is not interfered with.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
