Description

Technical Field

[0001] The invention relates to the technical field of full-automatic vacuum sealing formation of lead-acid batteries, and in particular to full-automatic vacuum sealing formation equipment and a process for lead-acid batteries. Background Art

[0002] Lead-acid batteries are low-priced, easy to use, and have stable performance. They have been widely used in various fields. As one of the main secondary power sources, they occupy a large share in the market. At this stage, the battery industry technology is constantly updated, the market competition is fierce, and the sales price is constantly declining. Reducing the manufacturing cost of batteries and improving production efficiency are the directions pursued by various manufacturers. Among them, the internal formation process of lead-acid batteries will affect the net charge capacity of the battery. Therefore, internal formation technology has become the key to further reducing costs and improving quality in the battery industry.

[0003] The patent document with patent number CN221407405U discloses a technical field involving an internal formation tank of a lead-acid battery, specifically an internal formation tank of a lead-acid battery, comprising: an internal formation tank body, a lead-acid battery body and a servo motor, wherein the lead-acid battery body is arranged inside the internal formation tank body, the servo motor is arranged on the side wall of the internal formation tank body, a cooling structure is arranged inside the internal formation tank body, an installation structure is arranged inside the internal formation tank body, the cooling structure comprises a water inlet seat, the water inlet seat is arranged at the right end of the internal formation tank body, one end of the water inlet seat is connected to a water inlet pipe, and a through hole is opened inside the water inlet pipe.

[0004] However, in actual use, the inventors found that if the exhaust hole on the battery cover is too small, the hydrogen and oxygen generated by the positive and negative electrodes will form a large internal pressure, which will bounce the cover or even cause an explosion. If the exhaust hole is too large, the air pressure inside the battery will decrease, which is not conducive to the conversion of active substances. At the same time, in order to prevent the leakage of polluting gases, the internal formation needs to be carried out in a closed space. When a problem occurs in a group of batteries and bulges, it cannot be handled in time, seriously affecting production efficiency. Summary of the invention

[0021] A fully automatic vacuum sealing formation process for lead-acid batteries, applied to a fully automatic vacuum sealing formation equipment for lead-acid batteries, comprises the following steps:

[0022] Step 1, cooling process. First, workers assemble the battery that needs internalization reaction with the battery cover plate and place them in the placement box accordingly. Then, the electrodes of multiple batteries are connected in series with power-on sheets. Then, the device is sent into the reaction tank for closed reaction. The pollutant gas generated by the internalization reaction is uniformly recovered and processed. During the process, the water immersion component in the cooling mechanism continuously applies water to both sides of the battery, and quickly takes away the heat generated inside the battery by evaporation to ensure the stability of the battery. At the same time, the identification mechanism determines the status of the battery.

[0023] Step 2, pressure control process, during the reaction process, when the internal gas pressure of the battery increases rapidly and the exhaust hole has no time to output, the balance component in the pressure control mechanism opens to quickly establish a closed space connected to the inside of the battery, and the gas is quickly transferred under the guidance of the gas pressure, so that the internal gas pressure of the battery becomes a specified value, and then the balance component automatically closes and separates from the internal space of the battery, and cooperates with the release component to release excess gas under the power of the immersion component to reset the balance component;

[0024] Step 3, transfer process, when a group of batteries have bulges, the identification component reacts quickly to lift the power-carrying plates on both sides of the corresponding battery, and cuts off the power supply of all batteries at the same time. Then the receiving component in the transfer mechanism transfers the battery and cooperates with the storage component to store the power-carrying plates on both sides of the battery;

[0025] Step 4, the reconnection process, when the battery is transferred, the balancing component cooperates with the release component to drive the extension component to unfold, and at the same time cancels the limit of the corresponding submerged component. Then the corresponding submerged component is fixed after moving down, so that the extension component is overlapped between the two groups of batteries, acting as a conductor, and finally the power-on status of all batteries is reconnected for unified response.

[0026] Beneficial effects of the present invention:

[0027] (1) In the present invention, a pressure control mechanism is provided to change the original fixed size of the exhaust hole, thereby maintaining the balance of the internal pressure of the battery during the internal formation process of the lead-acid battery. When the internal pressure of the battery increases rapidly, the balance component opens to establish a closed space connected to the inside of the battery, thereby quickly completing the recovery of the internal pressure of the battery. At the same time, it is ensured that the internal pressure of the battery will not be lower than the set value but fluctuates within a specified range, thereby ensuring the conversion of the active substances in the battery during the internal formation;

[0028] (2) In the present invention, a cooling mechanism is provided to change the original method of immersing the battery in a water pool to applying water on the surface of the battery, thereby quickly reducing the heat of the battery by evaporation and heat absorption, thereby improving the cooling efficiency and reducing the control of the circulating water temperature. In addition, under the action of the identification component, the device can quickly respond to the bulging battery, cut off the power supply in time and transfer it, thereby ensuring the safety of the working process;

[0029] (3) In the present invention, a transfer mechanism is provided to cooperate with a cooling mechanism, thereby timely transferring the faulty bulging battery. At the same time, during the transfer process, the power-carrying sheets at both ends of the battery are folded and stored in cooperation with the storage assembly, thereby reducing the impact of the faulty battery on the reaction area under the limited space in the reaction tank body;

[0030] (4) In the present invention, an extension component is provided. After the faulty battery is turned, the corresponding immersion component is separated from the main body in cooperation with the immersion component and the balance component. The water transport work is no longer performed up and down. Instead, the water is dropped and fixed to cooperate with the extension component to connect the two electrodes, acting as a conductor, thereby ensuring the normal internalization work.

[0031] In summary, the equipment has the advantages of rapid fault handling, good cooling effect, and stable fluctuation of internal battery air pressure, and is particularly suitable for the field of fully automatic vacuum sealing formation technology for lead-acid batteries.

[0055] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0056] Embodiment 1

[0057] like Figures 1 to 4 and Figures 17 to 21 As shown, a fully automatic vacuum sealing formation equipment for lead-acid batteries comprises:

[0058] A cooling mechanism 1, which is disposed on the reaction tank 100 and is used to cool the outer wall of the battery and identify the battery status;

[0059] A transfer mechanism 2, which is disposed on the cooling mechanism 1 and is used to move the faulty battery out of the reaction area;

[0060] A pressure control mechanism 3, which is disposed on the battery cover 200 and is used to control the internal pressure of the battery to fluctuate in a certain area;

[0061] The pressure control mechanism 3 includes a balancing component 31 disposed on the battery cover 200 and used to maintain the internal gas pressure of the battery, a releasing component 32 disposed on the cooling mechanism 1 and used to release the gas in the balancing component 31, and an extending component 33 disposed on the cooling mechanism 1 and used to reconnect the circuit.

[0062] In this embodiment, by setting the pressure control mechanism 3, the original fixed size setting of the exhaust hole 300 is changed, so as to maintain the balance of the internal air pressure of the battery during the internal formation process of the lead-acid battery. When the internal air pressure of the battery increases rapidly, the balance component 31 opens to establish a closed space connected to the interior of the battery, so as to quickly complete the recovery of the internal air pressure of the battery, and at the same time ensure that the internal air pressure of the battery will not be lower than the set value but fluctuate within the specified range, thereby ensuring the conversion of the active substance inside the battery during the internal formation.

[0063] In detail, first, workers assemble the battery that needs internalization reaction with the battery cover 200 and place them in the placement box 112 accordingly, and connect the electrodes of multiple batteries in series with the power-on sheet 400. Then the device is sent into the reaction tank 100 for a closed reaction, and the pollutant gas generated by the internalization reaction is uniformly recovered and processed. In the process, the cooling mechanism 1 applies water to both sides of the battery for cooling. When the internal air pressure of the battery increases, the cooling mechanism 1 drives the pressure control mechanism 3 to work together to release part of the gas inside the battery to maintain the internal air pressure of the battery stable. When a bulging battery appears, the transfer mechanism 2 cooperates with the cooling mechanism 1 to quickly transfer it away from the reaction area.

[0064] It should be noted that due to the relatively mature production of lead-acid batteries, battery quality problems rarely occur. When a batch of batteries are internally formed, if a battery bulges, it can be determined that a collision occurred during manual operation, causing the position of the internal battery plates to shift. At this time, the battery is quickly transferred through the cooling mechanism 1 and the transfer mechanism 2, and the circuit is re-established to continue the reaction. When a second battery bulges, all work needs to be stopped, and the batch of batteries must be withdrawn for re-inspection to eliminate problems with the mechanical installation work.

[0065] Further, if Figures 1 to 12 As shown, the cooling mechanism 1 includes a water immersion component 11 disposed on the reaction tank body 100 and used to apply water to both sides of the battery for evaporation and cooling, and an identification component 12 disposed on the water immersion component 11 and used to determine whether the battery is bulging.

[0066] In this embodiment, by providing a cooling mechanism 1, the heat generated by the lead-acid battery during the internal formation reaction is dissipated in time, thereby maintaining the internal temperature of the battery and reducing the occurrence of bulging and expansion of the battery under high temperature conditions.

[0067] In detail, when the internalization is working, the immersion component 11 transfers water to both sides of the battery through up and down movement, and quickly takes away the heat inside the battery through evaporation. At the same time, when the immersion component 11 moves, it drives the identification component 12 to move, and checks the status of the battery surface.

[0068] Further, if Figures 1 to 7 As shown, the immersion assembly 11 includes a placement box 112 with a water tank 111 and used to hold batteries, a mounting frame 114 arranged on the reaction tank body 100 and connected to a driving cylinder 113, a mounting plate 116 connected to the output end of the driving cylinder 113 and having a plurality of mounting grooves 115, a mounting rod 117 connected to the mounting groove 115, a immersion frame 118 connected to the mounting rod 117, a sponge layer 119 connected to the immersion frame 118, and a trigger 110 arranged on the mounting rod 117;

[0069] The trigger member 110 includes an inner rod 1101 arranged on the mounting rod 117, a limiting rod 1102 connected to one end of the inner rod 1101, a driving groove 1103 opened on the inner rod 1101, and a plurality of trigger blocks 1105 connected to the mounting frame 114 through a first telescopic member 1104 and arranged corresponding to the mounting rod 117.

[0070] In this embodiment, by providing an immersion component 11, the original method of immersing the battery in a water pool is changed to applying water on the surface of the battery, thereby quickly reducing the heat of the battery by evaporation and heat absorption, thereby improving the cooling efficiency and reducing the control of the circulating water temperature.

[0071] In detail, when the work starts, the driving cylinder 113 drives the mounting plate 116 to move up and down through the output end, and then the multiple groups of mounting rods 117 drive the immersion rack 118, and use the sponge layer 119 to absorb water to start cooling the battery.

[0072] It should be noted that during the cooling operation, the immersion rack 118 can only move down to a position just separated from the bottom of the battery, and will not move upward beyond the top of the battery, thereby facilitating the subsequent transfer of faulty batteries. The upper and lower edges of the drive slot 1103 are staggered.

[0073] Further, if Figures 8 to 12As shown, the identification component 12 includes two groups of mounting seats 121 arranged on the immersion frame 118, an identification rod 123 connected to the mounting seat 121 through a first spring 122, a limiting ball 125 connected to the identification rod 123 through a second spring 124, a limiting groove 126 arranged on the mounting seat 121 and used to cooperate with the limiting ball 125 to fix the position of the identification rod 123, two groups of supporting frames 127 connected to the immersion frame 118, two groups of connecting rods 128 connected to the immersion frame 118 and connected to the supporting frames 127 and the identification rod 123 at both ends, a first rack 129 connected to the connecting rod 128, a first gear 1210 arranged on the immersion frame 118 and respectively meshing with the two first racks 129 for transmission, and a sensor 1211 arranged on the immersion frame 118.

[0074] In this embodiment, by providing the identification component 12, the device can quickly respond to the swollen battery, cut off the power supply and transfer it in time, thereby ensuring the safety of the working process.

[0075] In detail, during the up and down movement of the immersion rack 118, the identification assembly 12 also moves accordingly. When a battery bulges, the identification rod 123 is squeezed by the bulge, and then the limiting ball 125 and the second spring 124 contract and move out of the limiting groove 126. At this time, the identification rod 123 continues to contract under the drive of the first spring 122, and then drives the support frame 127 on the other side to move through the connecting rod 128, and under the action of the first rack 129 and the first gear 1210, another group of support rods and the identification rod 123 also move. Finally, the support rods on both sides clamp the two sides of the battery and drag the bottom of the battery after moving downward.

[0076] It should be noted that when the identification rod 123 moves, the sensor 1211 transmits a signal to stop the power-on state of all batteries, thereby ensuring the consistency of the internal formation progress of the batteries.

[0077] Further, if Figure 1 to Figure 2 and Figures 13 to 16 As shown, the transfer mechanism 2 includes a receiving component 21 disposed on the cooling mechanism 1 and used to move the swollen battery out of the reaction area, and a receiving component 22 disposed on the receiving component 21 and used to receive the power sheet 400 on the battery.

[0078] In this embodiment, a transfer mechanism 2 is provided in cooperation with the cooling mechanism 1, so that the faulty bulging battery can be transferred in time. Meanwhile, during the transfer process, the power-carrying plates 400 at both ends of the battery are folded and stored in cooperation with the storage assembly 22, thereby reducing the impact of the faulty battery on the reaction area under the limited space in the reaction tank body 100.

[0079] In detail, when the swollen battery is lifted by the immersion component 11 and the identification component 12, the receiving component 21 moves to transfer the battery, and cooperates with the storage component 22 to store and fold the power-carrying sheets 400 on the electrodes on both sides of the swollen battery.

[0080] Further, if Figures 13 to 16 As shown, the receiving assembly 21 includes two groups of motors 211 connected to one side of the mounting frame 114, a storage frame 212 connected to the other side of the mounting frame 114, a first screw rod 213 connected to the output end of the motor 211 and connected to the storage frame 212, a transmission frame 214 connected to the two groups of first screw rods 213, a plurality of push plates 215 connected to the transmission frame 214, and a bottom plate 217 connected to the push plate 215 through a second telescopic member 216;

[0081] The storage assembly 22 includes a second screw rod 222 connected to the push plate 215 and having one end connected to a second gear 221, a second rack 223 connected to the base plate 217 and meshing with the second gear 221, a first shifting rod 224 connected to the second screw rod 222, an extrusion rod 225 connected to the storage rack 212, and a second shifting rod 227 connected to the storage rack 212 via a third spring 226.

[0082] In this embodiment, the push plate 215 and the bottom plate 217 are separated from each other to make it easier for the battery to be transferred to the storage rack 212. At the same time, in the process of the two moving relative to each other, the storage assembly 22 can quickly complete the storage of the power-carrying plates 400 on both sides, ensuring that the fixed battery will not block the extension assembly 33 after leaving the reaction area.

[0083] In detail, the motor 211 drives the first screw rod 213 to rotate through the output end, and then drives the plurality of push plates 215 and the bottom plate 217 to move together through the transmission frame 214. After contacting the battery, the push plate 215 pushes the battery by squeezing so that the battery is received by the bottom plate 217. Then, the battery reaches the storage rack 212 under the drive of the bottom plate 217, and the bottom plate 217 is limited by the storage rack 212. During the process, the bottom plate 217 contacts the squeezing rod 225 and drives the squeezing rod 225 to move, and the squeezing rod 225 pushes the second lever 227 to move. Then, the push plate 215 continues to move to push all the batteries onto the storage rack 212. During the process, the push plate 215 drives the second gear 221 to move and mesh with the second rack 223 for transmission, and drives the second screw rod 222 to rotate when rotating. The second screw rod 222 then drives the first lever 224 to move, and then the power-carrying sheet 400 on one side is rotated and stored. Then, when the bottom plate 217 leaves, the squeezing of the squeezing rod 225 is cancelled. Driven by the third spring 226, the second lever 227 is reset, and drives the power-carrying sheet 400 on the other side to be stored.

[0084] It should be noted that a groove is provided on the bottom plate 217 to avoid the support frame 127 .

[0085] Further, if Figures 17 to 19 As shown, the balancing assembly 31 includes a connecting tube 311 connected to the battery cover 200, a limiting frame 312 connected to the battery cover 200, a folding airbag 313 connected to the limiting frame 312 and the bottom of which is connected to the connecting tube 311, a shaft rod 314 connected to the connecting tube 311, a piston 315 connected to the shaft rod 314, a fixing groove 316 opened on the shaft rod 314, and a fixing block 318 connected to the connecting tube 311 through a third telescopic member 317 and used to fix the position of the shaft rod 314.

[0086] In this embodiment, the balance component 31 is provided so that the air pressure inside the battery can be automatically detected. Once the designated air pressure folding airbag 313 entrance is reached, it will be connected to the inside of the battery and the air pressure will be quickly reduced through large-aperture transmission.

[0087] In detail, when the air pressure increases, the exhaust hole 300 can no longer meet the exhaust demand, and the pressure acts on the piston 315, causing the piston 315 to gradually break through the limiting effect of the third telescopic member 317 on the fixed block 318. When the limit value is reached, the piston 315 drives the shaft rod 314 to move upward, and the fixed block 318 moves out of the fixed groove 316. The connecting tube 311 is opened and the gas quickly moves from the inside of the battery to the folded airbag 313. Since the airbag is a sealed structure, the internal air pressure quickly reaches stability. At this time, the piston 315 and the shaft rod 314 fall freely to cover the connecting tube 311.

[0088] It should be noted that the folded airbag 313 is connected to the limiting frame 312 at the top and bottom in a plate shape and has a certain hardness.

[0089] Further, if Fig. 9 and Figures 17 to 20 As shown, the release assembly 32 includes a release port 321 opened at the top of the folding airbag 313, two sets of sealing plates 323 connected to the folding airbag 313 through a fourth spring 322, and a cone plate 325 connected to the immersion frame 118 through a fourth telescopic member 324.

[0090] It is worth mentioning here that the release assembly 32 is driven by the immersion rack 118 to work, so that the gas in the balance assembly 31 can be discharged in time to facilitate the next work.

[0091] In detail, when the immersion frame 118 falls from top to bottom, the conical plate 325 connected to the immersion frame 118 squeezes the two sets of sealing plates 323 on the top of the folding airbag 313, causing the fourth spring 322 to shrink and the release port 321 to open. At the same time, when the conical plate 325 moves downward, the instantaneous squeezing increases the internal air pressure of the folding airbag 313, thereby impacting the piston 315 to drive the shaft rod 314 to move, and the fixing block 318 re-engages with the fixing groove 316.

[0092] It should be noted that the squeezing pressure during the release process is not sufficient to drive the fourth telescopic member 324 to extend.

[0093] Embodiment 2

[0094] like Figures 8 to 9 and Fig.21 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0095] Further, if Figures 8 to 9 and Fig.21 As shown, the extension assembly 33 includes a sleeve plate 331 connected to the immersion frame 118, two groups of extension plates 333 connected to the sleeve plate 331 through a fifth telescopic member 332, an L-shaped rod 334 connected to the extension plate 333, a positioning rod 335 connected to the fourth telescopic member 324 and used to fix the position of the L-shaped rod 334, and a driving rod 336 connected to the positioning rod 335 and one end of which is located in the driving groove 1103.

[0096] In this embodiment, by providing an extension component 33, after the faulty battery is turned, the corresponding immersion component 11 is separated from the main body in cooperation with the immersion component 11 and the balance component 31, and the water is no longer transported up and down reciprocatingly. Instead, it falls down and is fixed to cooperate with the extension component 33 to connect the two electrodes, acting as a wire, thereby ensuring the normal internalization work.

[0097] In detail, when the push plate 215 pushes the battery to move, the side of the cone plate 325 is squeezed by the edge of the release port 321, so that the fourth telescopic member 324 drives the cone plate 325 to retract upward. After the battery is transferred, the fourth telescopic member 324 is reset. During the process, the fourth telescopic member 324 moves upward to drive the positioning rod 335 to move upward, thereby releasing the limit on the L-shaped rod 334. The two sets of extension pieces 333 are extended to the specified length under the action of the fifth telescopic member 332. At the same time, the fourth telescopic member 324 drives the driving rod 336 to complete an up and down movement, and then drives the inner rod 1101 to rotate 90° under the cooperation of the driving rod 336 and the driving slot 1103. At this time, the limiting rod 1102 is aligned with the installation slot 115. When the bulge After the battery transfer is completed, the driving cylinder 113 drives the immersion frame 118 to move downward until the extension piece 333 is connected to the corresponding electrode. Due to the friction between the mounting rod 117 and the mounting groove 115, when the limiting rod 1102 moves downward with the mounting rod 117, the trigger block 1105 is squeezed to make it avoid. Then, the trigger block 1105 is driven by the first telescopic member 1104 to get on the top of the column limiting rod 1102. When the driving cylinder 113 drives the mounting plate 116 to move upward, the corresponding mounting rod 117 is separated from the mounting groove 115 under the limit of the trigger block 1105, thereby ensuring that the extension piece 333 works as a wire to connect the circuit. Finally, all batteries are powered on again to continue the internalization reaction.

[0098] It should be noted that the two groups of extension pieces 333 are internally connected with wires.

[0099] Embodiment 3

[0100] like Fig. 22 As shown, a fully automatic vacuum sealing formation process for lead-acid batteries is applied to a fully automatic vacuum sealing formation equipment for lead-acid batteries, comprising the following steps:

[0101] Step 1, cooling process, first the worker assembles the battery that needs internalization reaction with the battery cover plate 200 and places them in the placement box 112 accordingly, and connects the electrodes of multiple batteries in series with the power supply sheet 400, and then sends the device into the reaction tank 100 for closed reaction, and uniformly recovers and treats the pollutant gas generated by the internalization reaction. During the process, the immersion component 11 in the cooling mechanism 1 continuously applies water to both sides of the battery, and quickly takes away the heat generated inside the battery by evaporation to ensure the stability of the battery. At the same time, the identification mechanism determines the state of the battery;

[0102] Step 2, pressure control process, during the reaction process, when the internal gas pressure of the battery increases rapidly and the exhaust hole 300 has no time to output, the balance component 31 in the pressure control mechanism 3 opens to quickly establish a closed space connected to the inside of the battery, and the gas is quickly transferred under the guidance of the gas pressure, so that the internal gas pressure of the battery becomes a specified value, and then the balance component 31 automatically closes and separates from the internal space of the battery, and cooperates with the release component 32 to release excess gas under the power of the immersion component 11 to reset the balance component 31;

[0103] Step 3, transfer process, when a group of batteries have bulges, the identification component 12 reacts quickly to lift the power-carrying pieces 400 on both sides of the corresponding battery, and cuts off the power supply of all batteries at the same time. Then the receiving component 21 in the transfer mechanism 2 transfers the battery and cooperates with the storage component 22 to store the power-carrying pieces 400 on both sides of the battery;

[0104] Step 4, the reconnection process, when the battery is transferred, the balancing component 31 cooperates with the release component 32 to drive the extension component 33 to unfold, and at the same time cancels the limit of the corresponding immersion component 11, and then the corresponding immersion component 11 is fixed after moving down, so that the extension component 33 is overlapped between the two groups of batteries, acting as a conductor, and finally the power-on status of all batteries is reconnected for unified response.
