Description

Technical Field

[0001] This invention relates to the field of storage battery technology, specifically to a storage battery and its continuous charging device. Background Technology

[0002] A storage battery is a device that stores electrical energy by converting it into chemical energy through a chemical reaction. It consists of one or more battery cells, each containing a positive electrode, a negative electrode, and an electrolyte. During charging, electrical energy is converted into chemical energy and stored; during discharging, chemical energy is converted back into electrical energy and released.

[0003] The initial charging process in battery production is crucial for ensuring battery performance and lifespan. The purpose of initial charging is to convert lead oxide, which forms over time due to exposure to air, into active materials that can participate in electrochemical reactions. Simultaneously, it allows the electrolyte to fully react with the plates, restoring the battery's capacity. After the initial charging, further charging is required. However, to ensure safety during transportation, batteries are typically not fully charged when they leave the factory. A fully charged battery may cause safety issues during transport due to vibration, impact, or short circuits, such as overheating, leakage, or even fire. Therefore, to meet transportation safety standards, batteries are usually maintained at a lower state of charge when they leave the factory.

[0004] Currently, the initial charging of batteries after production requires moving them to a charging rack, manually installing the positive and negative terminals, and then charging them. This charging process makes it impossible to accurately control the charging time, and staff also need to record the charging time of each batch of batteries to ensure that the battery capacity is in a safe state. As a result, staff need to check all batteries at regular intervals to avoid overcharging, which greatly increases the workload of the staff. In addition, manually installing the positive and negative terminals also poses certain dangers. Summary of the Invention

[0012] Preferably, the charging compartment also includes a battery, which cooperates with the charging interface group to complete the charging connection.

[0013] Preferably, the battery is further provided with two battery connection posts, and two pin slots are provided inside the battery. A magnetic block is fixed inside the pin slots, and the pin slots open upwards and towards the side closer to the battery connection posts, respectively.

[0014] Preferably, the charging interface group includes a charging pin that slides within the charging turntable. Both ends of the charging pin extend downwards. A baffle is fixed to the end face of the charging pin away from the battery. A clamping pin is also fixed inside the charging pin. The clamping pin is electrically connected to the main power supply. The clamping pin is fork-shaped, with an elastic arc plate fixed in its middle portion. The two edges of the charging pin near the battery are chamfered and have magnetism. The other parts of the charging pin are made of an insulator.

[0015] A telescopic rod is installed between the clamping pin and the inner wall of the charging pin. The telescopic rod is divided into two parts and is slidably connected to each other. The inside of the telescopic rod is hollow and filled with paraffin wax. One part of the telescopic rod is fixed to the end of the clamping pin, and the other part is fixed to the side wall of the extension of the charging pin. The elastic arc plate of the clamping pin is connected to the charging pin through a fixed shaft.

[0016] Preferably, the chassis rotates on the support column, and a protruding block is fixed on the outer periphery of the chassis, with a limit block rotatably connected to the protruding block.

[0017] Preferably, the upper surface of the cover is provided with a ventilation groove, and the outer periphery of the cover is also provided with a number of heat dissipation holes and a feed inlet.

[0019] Compared with the prior art, the present invention provides a storage battery and a continuous charging device thereof, which has the following beneficial effects:

[0020] 1. This type of storage battery and its continuous charging device, through the cooperation of a rotating charging turntable and a chassis, changes the curvature between the timing hole and the feed inlet of the top cover to control the duration of the storage battery's stay in the charging compartment, thereby controlling the charging time of the storage battery. This allows the storage battery to automatically disconnect according to the set charging time, making it suitable for the charging time of most storage batteries. It can effectively avoid safety problems such as short circuits and fires caused by overcharging of the storage battery at the factory and vibration and collision during transportation and storage. Moreover, since the storage battery is automatically fed, connected, and disconnected, no manual intervention is required, greatly increasing its safety.

[0021] 2. This type of storage battery and its continuous charging device, through a timed motor driving the charging turntable to move intermittently, enables the storage battery to be automatically and continuously charged during the production process. After charging, the dropped storage battery can be manually handled or automatically transported by a guide rail mechanism for the next operation. The entire process requires minimal human intervention, and the interval between each handling is extremely long. Workers do not need to conduct continuous phased inspections in a short period of time, and the entire equipment can work continuously without interruption, greatly improving its work efficiency.

[0022] 3. The battery and its continuous charging device, through the setting of the auxiliary plate, the movable needle roller on the upper end face can greatly reduce the friction when the battery enters the charging compartment, making the battery move more easily. The movable ball at the bottom of the auxiliary plate can maintain the stability of the battery in the charging compartment when the charging turntable rotates, avoiding the phenomenon of relative movement. It can also isolate the battery from the chassis when the chassis and the charging turntable rotate relative to each other, avoiding contact between the two and causing sliding friction, which would lead to wear of the battery.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1-9 As shown, it includes a base 10, on which a support column 11 and a support rod 12 are fixed. A top cover 13 is fixed on the support rod 12. The top cover 13 has an opening facing downward. A charging device and a chassis 30 are disposed inside the top cover 13. The charging device rotates inside the top cover 13. The chassis 30 is disposed at the bottom of the top cover 13 and abuts against the charging device.

[0035] The charging device includes a charging turntable 20, the bottom of which extends downward into the support column 11. A charging gear 202 is fixed at the bottom of the turntable 20. Several charging chambers 203 are provided on the outer periphery of the turntable 20, each opening downwards. A charging interface assembly is movably disposed within each charging chamber 203. An annular wire connection groove 201 is also provided on the upper surface of the turntable 20, with part of the charging interface assembly located within the wire connection groove 201. Several connecting holes are provided on the inner end face of the charging chambers 203, communicating with the wire connection groove 201. The battery can be charged within the 03 compartment, and the heat generated during charging can be discharged through the connecting hole. Wires can be connected within the wire connection slot 201, and the heat generated at the wire connection point and the heat discharged from the connecting hole can both be discharged through the wire connection slot 201. If necessary, fan blades can be installed at the bottom of the wire connection slot 201 to accelerate airflow and dissipate heat. The charging turntable 20 and the support rod 12 are in a state of relative rotation. A conductive slip ring can be fitted onto the support rod 12 and connected to the wires within the charging turntable 20 to provide power.

[0036] Movable auxiliary plates 204 are provided on the two bottom edges inside the charging compartment 203. The auxiliary plates 204 are connected to the inner wall of the charging compartment 203 via a rotating shaft. A torsion spring is provided on the rotating shaft, which can reset the auxiliary plates 204 after rotation. At least two movable balls are provided at the bottom of the auxiliary plates 204, and the movable balls abut against the end face of the chassis 30. At least two movable needle rollers are provided on the upper end face of the auxiliary plates 204. Through the design of the auxiliary plates 204, the movable needle rollers on the upper end face can greatly reduce the friction when the battery enters the charging compartment 203, making the battery move more easily. When the battery enters the charging compartment, it can directly enter under the action of inertia. The movable balls at the bottom of the auxiliary plates 204 can maintain the stability of the battery in the charging compartment 203 when the charging turntable 20 rotates, avoiding the phenomenon of relative movement. They can also isolate the battery 50 from the chassis 30 when the chassis 30 and the charging turntable 20 rotate relative to each other, avoiding contact and sliding friction, which would cause wear on the battery 50.

[0037] The upper surface of the charging turntable 20 also has at least two air holes 21. A cooling fan 211 is installed in the air hole 21. The bottom of the air hole 21 is connected to the wire connection groove 201. The cooling fan 211 can quickly dissipate the heat inside the cover 13 and the support rod 12 to avoid heat accumulation, which could lead to overheating of the circuit and fire or other safety hazards.

[0038] The charging compartment 203 also includes a battery 50. The battery 50 cooperates with the charging interface assembly to automatically complete the charging connection, eliminating the need for manual connection by staff and greatly reducing their workload. Two battery connection posts 51 are fixed on the battery 50, and two pin slots 501 are formed inside the battery 50. A magnet 502 is fixed inside each pin slot 501. The pin slots 501 open upwards and towards the side closest to the battery connection posts 51, respectively. The charging interface assembly includes a charging pin 40, which slides within the charging turntable 20. Both ends of the charging pin 40 extend downwards. A baffle 401 is fixed to the end face of the charging pin 40 away from the battery 50. The baffle 401 is located inside the wire connection groove 201 and can abut against the inner wall of the wire connection groove 201 to limit the position of the charging pin 40. A clamping pin 41 is also fixed inside the charging pin 40 and is electrically connected to the main power supply. The clamping pin 41 is shaped like a fork, with an elastic arc plate fixed in the middle. The two ends of the charging pin 40 near the battery 50 are beveled and magnetic. The rest of the charging pin 40 is made of insulator. With the charging pin 40 and the magnetic block 502, after the battery 50 enters the charging compartment 203, the two attract each other, and the charging pin 40 can enter the pin groove 501 and be attracted together with the magnetic block 502. This allows the battery 50 to be fully inserted into the charging compartment 203, preventing the charging turntable 20 from being stuck by the battery 50 when it rotates. The mutual attraction between the two also connects the battery connecting post 51 on the battery 50 to the clamping pin 41 on the charging pin 40, completing the electrical connection. At this time, the battery can be charged. At the same time, it can also prevent the centripetal force generated when the charging turntable 20 drives the battery 50 to rotate, which would cause the clamping pin 41 to disengage from the battery connecting post 51.

[0039] A telescopic rod 42 is installed between the clamping pin 41 and the inner wall of the charging pin 40. The telescopic rod 42 is divided into two parts and is slidably connected to each other. The interior of the telescopic rod 42 is hollow and filled with paraffin wax. One part of the telescopic rod 42 is fixed to the end of the clamping pin 41, and the other part is fixed to the side wall of the extension of the charging pin 40. The elastic arc of the clamping pin 41 is connected to the charging pin 40 through a fixed shaft, which limits the position of the clamping pin 41. The initial state of the two telescopic rods 42 is to stretch the bottom of the clamping pin 41 outward, so that the head of the clamping pin 41 is pressed inward. After the clamping pin 41 enters the battery 50, it can better abut against the battery connection post 51, ensuring the stability of the battery connection. During the charging process of the battery, if there are impurities (such as rust) at the contact point of the battery connection post 51, it will increase its resistance, so the heat generation during the charging process will be more serious. The internal temperature rises rapidly, which may cause high-temperature damage to the circuit. Therefore, the heat generated at the battery contact points will be conducted to the telescopic rod 42 through the clamping pin 41, causing the telescopic rod 42 to heat up. This will melt the paraffin inside the telescopic rod 42, increasing its volume and causing the telescopic rod 42 to extend. The extended telescopic rod 42 will push the bottom of the clamping pin 41 inward to clamp it, while its head opens to both sides, thus disengaging from the battery connection post 51 and stopping the battery from charging. This prevents the battery from overheating and causing damage or fire. However, due to external influences, the internal temperature of the battery compartment may become too high, which may also cause the clamping pin 41 to disconnect from the battery connection post 51. If the temperature is too high, the battery is more likely to catch fire during charging. However, once the temperature drops to a safe level, the paraffin inside the telescopic rod 42 will solidify, causing the telescopic rod 42 to retract. This allows the clamping pin 41 to clamp onto the battery connection post 51 again, and charging can resume.

[0040] A timing hole 301 is provided on the chassis 30. The opening size of the timing hole 301 is larger than the lower opening size of a single charging compartment 203. The chassis 30 rotates on the support column 11. A protruding block 302 is also fixed on the outer periphery of the chassis 30. A limit block 303 is rotatably connected to the protruding block 302. A ventilation groove 131 is provided on the upper end face of the top cover 13. Several heat dissipation holes and a feeding port are also provided on the outer periphery of the top cover 13. The feeding port is located at the battery transfer position. Several limit buckles 132 are also fixed on the outer periphery of the top cover 13. Between every two adjacent limit buckles 132 The gap size is consistent with that of the limit block 303. A conveyor belt is set at the feed inlet of the upper cover 13. The conveyor belt transports the finished batteries 50. The start interval of the conveyor belt is consistent with the rotation interval of the charging turntable 20. Each time the conveyor belt starts, it pushes the previous battery 50 into the charging compartment 203 through the next battery 50. The whole process does not require manual placement and has a high degree of automation. The chassis 30 is set so that the position of the timing hole 301 can be controlled by rotating the chassis 30 to correspond to one of the charging compartments 203. The position of the timing hole 301 can be adjusted. The charging time of the battery 50 is controlled by a timer hole 301 located four charging chambers 203 away from the feed inlet of the top cover 13. When the battery 50 at the feed inlet enters the charging chamber 203, it begins charging. Within a set time (which can be activated once per hour), the charging turntable 20 rotates once. After the charging turntable 20 rotates five times consecutively, the charging chamber 203 at this location aligns with the timer hole 301, and the battery 50 inside will fall out of the charging chamber 203 under its own weight, disconnecting the battery 50 and completing the initial charging. This effectively prevents the battery from falling out of the charging chamber 203. Overcharging can cause safety issues such as short circuits and fires due to vibration and collisions during transportation and storage. Subsequently, the batteries are charged after five set time intervals, allowing for automated continuous charging during production. Batteries that have been fully charged and have fallen off can be handled manually or transported automatically via a guide rail mechanism for the next step. The entire process requires minimal human intervention, and the intervals between each handling are extremely long. This eliminates the need for staff to conduct periodic checks in a short period, and the equipment can operate continuously without downtime.

[0041] A collection tray 70 is rotatably connected to the outer periphery of the support column 11. The collection tray 70 is made of a soft material to prevent the battery from becoming unstable due to falling and impact. A gear ring 701 is fixed to the bottom of the collection tray 70. A timer motor 60 is installed on the base 10. The timer motor 60 is equipped with a motor shaft 61. A first gear 611 and a second gear 612 are fixed on the motor shaft 61. The first gear 611 meshes with the gear ring 701, and the second gear 612 meshes with the charging gear 202. The timer motor 60 is equipped with a timer, which can be set to start automatically at a set time. The motor shaft 61 rotates with the same arc as the charging compartment 203 each time it is turned on and off. That is, each time the charging compartment 203 is rotated, the charging turntable 20 is rotated by the timer motor 60, which also drives the collection tray 70 to rotate synchronously. This allows the batteries 50 to fall evenly onto the collection tray 70 until the collection tray 70 is completely filled. The time it takes for the collection tray 70 to be filled is greatly extended. The staff only needs to collect the batteries once every long period of time, without any other operations, which greatly reduces the workload of the staff.

[0042] Working principle: During use, the battery 50 is conveyed to the charging compartment 203 by the conveyor belt. Then, under the action of the movable needle roller on the auxiliary plate 204, the battery 50 easily enters the charging compartment 203. Then, the charging pin 40 attracts the magnetic block 502, allowing the battery 50 to be fully inserted into the charging compartment 203. The clamping pin 41 also clamps it together with the battery connecting post 51 for charging. However, after the timer set on the timer motor 60 reaches the set time, the timer motor 60 will drive the motor shaft 61 to rotate. The rotation of the motor shaft 61 will drive the first gear 611 and the second gear 612 to rotate together. The second gear 612 can drive the charging turntable 20 to rotate through the charging gear 202. The first gear 611 will drive the collecting tray 70 to rotate through the gear ring 701, so that the next charging compartment 203 corresponds to the feeding port on the top cover 13. The conveyor belt also moves accordingly. As the timer motor 60 rotates, the next battery 50 is fed into the next charging compartment 203 for charging. Each time the charging turntable 20 rotates, a new battery 50 is added to the next empty charging compartment 203. When the charging compartment 203 where the first battery 50 is located corresponds to the timer hole 301, the battery 50 inside will fall out of the charging compartment 203 under its own weight, disconnecting the battery 50 at that point and completing the charging process. The fallen battery 50 will fall onto the collection tray 70 and be temporarily collected. When the collection tray 70 is full of batteries 50, the staff can remove the batteries 50 to proceed to the next step. After the battery 50 falls, the auxiliary plate 204 is reset under the action of the torsion spring, and the charging compartment 203 is empty, allowing the next battery 50 to be charged, thus enabling continuous and uninterrupted charging.

[0043] When it is necessary to set the charging time of the battery 50, the limit block 303 can be pulled down to rotate the chassis 30, so that the timing hole 301 is in different charging chambers 203, thereby changing the curvature between the timing hole 301 and the feed port of the top cover 13, thereby controlling the charging time of the battery 50.

[0044] In summary, this type of battery and its continuous charging device, through the cooperation of the rotating charging turntable 20 and the chassis 30, and by changing the curvature between the timing hole 301 and the feed inlet of the upper cover 13, controls the duration of the battery 50's stay in the charging chamber 203, thereby controlling the charging time of the battery 50. This allows the battery 50 to automatically disconnect according to the set charging time, adapting to the charging duration of most batteries. It effectively avoids safety issues such as overcharging of batteries at the factory, leading to short circuits and fires due to vibration and collision during transportation and storage. Furthermore, since the battery 50 is automatically fed, connected, and disconnected, no manual intervention is required, greatly increasing safety. The intermittent movement of the charging turntable 20 driven by the timing motor 60 allows for automated continuous charging of the battery during production. Batteries that fall after charging can be discharged... The equipment can be transported automatically via guide rails or manually, allowing for further automated operations. This process requires minimal human intervention and minimizes the time intervals between transport operations, eliminating the need for continuous, phased inspections by staff. Furthermore, the equipment can operate continuously without downtime, significantly improving efficiency. The auxiliary plate 204's movable needle rollers on its upper surface greatly reduce friction when the battery enters the charging compartment 203, making battery movement easier. The movable ball at the bottom of the auxiliary plate 204 maintains the stability of the battery within the charging compartment 203 when the charging turntable 20 rotates, preventing relative movement. It also isolates the battery 50 from the chassis 30 when the chassis 30 rotates relative to the charging turntable 20, preventing sliding friction and wear on the battery 50.
