Description

Technical Field

[0001] This invention belongs to the field of lead-acid battery production technology, specifically a lead-acid battery electrode group welding device. Background Technology

[0002] A lead-acid battery electrode group refers to the positive and negative electrodes in a lead-acid battery. Lead-acid batteries are a common type of battery, widely used in automobiles, UPS power supplies, solar panels, and other fields. The positive and negative electrodes of a lead-acid battery are made of different materials, and they play different roles during the battery's charging and discharging process. An electrode group is a group of plates connected in series inside a battery and matched according to their capacity. Typically, multiple groups of positive and negative plates are arranged alternately and welded together.

[0003] In existing lead-acid battery electrode group welding devices, positive and negative electrode plates are typically arranged at intervals. After arrangement, multiple sets of battery plates are clamped together using a clamping part. The plates are moved so that their extreme ends are inserted into a solder bath for tin plating. After cleaning, the clamped plates are transferred back to the welding lead bath for welding. However, when removing the plates from the solder bath, a large amount of molten solder adheres to the extreme ends. Typically, the clamping assembly is moved to a sponge layer, and the molten solder is removed by friction through up-and-down movement. However, due to limitations in clamping stability, the range and speed of the up-and-down movement are restricted. The actual cleaning effect is poor when relative to the sponge layer during up-and-down movement, leaving some molten solder residue. This residue then causes sputtering during subsequent welding in the lead bath. In practice, the electrode group welding stability of multiple electrode plates is poor, resulting in poor performance.

[0004] Furthermore, in existing lead-acid battery electrode group welding devices, the temperature at the electrode group is too high after welding is completed. Cooling treatment is usually required at the electrode group welding site. Current welding devices require additional cooling equipment, along with a cooling power unit, to achieve water cooling or air cooling. However, the actual requirements for the welding device are higher, the structure is more complex, and the investment of multiple power units greatly increases the difficulty of structural planning. The layout effect is subject to operational interference, resulting in poor actual use performance. Summary of the Invention

The distribution frame is fixedly connected to the side of the welding lead pool, the exhaust pipe is fixedly connected to the top of the distribution frame, and the side of the distribution frame is fixedly connected to the other end of the side pipe.

[0013] Preferably, the bottom surface of the bottom frame is provided with an adapter groove, the inner surface of the adapter groove is fixedly connected to the mounting cylinder, the side of the bottom frame is provided with a convex groove, the top of the bottom frame is provided with a sliding groove, the bottom surface of the movable plate is fixedly connected with a side plate, and the side of the side plate is fixedly connected with a spring.

[0014] Preferably, the inner surface of the convex groove is adapted to the structure of the movable plate and the sponge layer, the inner surface of the convex groove is movably sleeved with the movable plate and the sponge layer, and the sliding groove is movably sleeved with the impact assembly.

[0016] Preferably, the top frame is fixedly mounted on top of the bottom frame, the clamping part is located above the solder bath, and the clamping part is slidably connected to the top of the inner surface of the top frame.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention utilizes the connection between an air supply component and a rotating component. During post-tinning cleaning, the air supply component inputs gas into the rotating component, using high-speed airflow to drive the fan blades within the rotating component, thereby rotating the shaft. This, in turn, drives the gears to rotate. The teeth on the bottom of the movable plate mesh with the gears, propelling the movable plate laterally. This causes the sponge layer to move laterally, resulting in a larger amplitude and more proactive relative friction cleaning. Simultaneously, the lateral movement of the movable plate rapidly moves the impact component on one side. The downward-sloping tubes in the impact component cause the tilted impact balls to rapidly strike one side of the clamping part, vibrating the clamping part and the battery plates. This vibration further separates the molten solder, significantly improving the actual effect and preventing residual molten solder from splashing into the solder bath. This improves subsequent soldering quality while maintaining safety at the soldering site, resulting in excellent performance.

[0019] 2. This invention utilizes the input air from the air supply component. When the fan blades are driven and the gears are rotated, the blown air enters the cleaning frame through the air outlet. This, combined with the movable plate fitted into the cleaning frame, completes the relative dynamic seal of the cleaning frame. This allows the continuously blowing air to be ejected quickly through the through hole on the bottom surface of the movable plate. Thus, when the solder coating is completed and the solder is cleaned, the upward blowing air provides the airflow to clean the battery's extreme points, cooling and removing dust. This further improves the cleaning effect while ensuring the stability of the battery's extreme points to be soldered.

[0020] 3. This invention reuses the air supply component, along with the control valve within it. After cleaning, as the positive and negative electrode plates of the battery complete the extreme electrode group welding, and as the battery electrode plates are moved upwards out of the welding lead pool and placed on top, air is supplied to the purging component. This allows the incoming air to be blown along the outlet curved pipe towards the welding area of ​​the battery electrode group, thereby achieving both the removal of residual lead and the removal of heat, resulting in rapid cooling. Furthermore, the power equipment used for cleaning and heat dissipation is shared, and the arrangement of the cooling purging component is simple, requiring no additional power equipment, resulting in good performance.

[0030] 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.

[0031] like Figures 1 to 8 As shown, this embodiment of the invention provides a lead-acid battery electrode group welding device, including a bottom frame 1, a top frame 2 and a clamping part 3. The bottom surface of the inner surface of the bottom frame 1 is provided with a solder pool 4, a cleaning frame 5 and a welding lead pool 6 from left to right. A movable plate 7 is movably sleeved inside the cleaning frame 5. A sponge layer 8 is fixedly connected to the top of the movable plate 7. Impact components 9 are provided on both the left and right sides of the top of the movable plate 7. Teeth 10 are provided on the bottom surface of the movable plate 7. A rotating component 12 is provided inside the cleaning frame 5. One end of the rotating component 12 is engaged with the teeth 10. An air supply component 13 is fixedly installed on the bottom surface of the inner surface of the bottom frame 1. One end of the air supply component 13 is connected to the rotating component 12. A blowing component 14 is provided on the side of the welding lead pool 6. The blowing component 14 is connected to the other end of the welding lead pool 6.

[0032] The rotating assembly 12 includes a mounting cylinder 121, a rotating shaft 122, a gear 123, a fan blade 124, and an air outlet 125;

[0033] The impact assembly 9 includes a vertical rod 91, an inclined tube 92, a movable plug 93, a sliding rod 94, and a billiard ball 95.

[0034] First embodiment: When welding is required, the positive and negative electrode plates of the lead-acid battery are installed alternately and spaced apart, so that the clamping part 3 in the top frame 2 moves laterally and clamps the stacked positive and negative electrode plates after descending. Then, the clamping part 3 moves and sends the positive and negative electrodes to the top of the solder pool 4. The positive and negative electrodes are lowered and the electrode ends are placed in the solder pool 4 to complete the solder coating. The positive and negative electrodes are moved up and taken out and moved to the top of the cleaning frame 5. The positive and negative electrode plates are lowered again. The air supply component 13 is started, so that the air pump 131 delivers gas to the rotating component 12 through the control valve 132. As the high-pressure air is delivered to the mounting cylinder 121 of the rotating component 12, the high-pressure air drives the fan blade 124 to rotate, and causes the rotating shaft 122 to rotate. As the fan blade 124 rotates, the gas is blown out along the through hole 15. At the same time, the rotating shaft 122 drives the gear 123 to rotate, so that the gear 123 passes through the meshing teeth 10. The movable plate 7 moves laterally, which in turn moves the sponge layer 8 laterally. The sponge layer 8 moves laterally and comes into contact with the extreme ends of the tin-coated battery, rubbing away the molten solder adhering to the surface. At the same time, the moving movable plate 7 moves the impact component 9 on one side laterally, causing the downward-sloping impact ball 95 to move quickly and collide with one side of the clamping part 3, causing the clamping part 3 and the clamped positive and negative plates to vibrate simultaneously. The molten solder and dust adhering to the surface are quickly vibrated and removed. At the same time, one side of the spring 21 is compressed while the other side of the spring 21 is stretched. When the air supply is cut off, the spring 21 elastically resets and moves the movable plate 7 to reset. Under inertia, the impact component 9 on the other side quickly impacts the clamping part 3 on the other side, completing the thorough cleaning and liquid removal. The gas blown into the cleaning frame 5 is blown upward quickly through the through hole 15 on the bottom surface of the movable plate 7 and blown upward along the bottom of multiple sets of positive and negative plates.

[0035] First, by utilizing the connection between the air supply component 13 and the rotating component 12, during the cleaning process after tinning, the air supply component 13 inputs gas into the rotating component 12. The high-speed airflow drives the fan blades 124 in the rotating component 12 to rotate, thereby rotating the shaft 122. This, in turn, drives the gear 123 to rotate. The teeth on the bottom surface of the movable plate 7 mesh with the gear 123, causing the movable plate 7 to move laterally. This allows the sponge layer 8 to move laterally and rub, achieving a larger amplitude and more proactive relative friction cleaning. Simultaneously, the lateral movement of the movable plate 7 quickly moves the impact component 9 on one side. The downward-sloping tube 92 in the impact component 9 causes the inclined ball 95 to quickly impact one side of the clamping part 3, thereby vibrating the clamping part 3 and the battery plate. The vibration effect further separates the molten solder, greatly improving the actual effect and preventing residual molten solder from splashing in the soldering lead pool. This improves the subsequent soldering quality while maintaining the safety of the soldering site, resulting in good performance.

[0036] Furthermore, by utilizing the input air from the air supply component 13, when the fan blade 124 is driven and the gear 123 is rotated, the blown air enters the cleaning frame 5 through the air outlet 125. This, in conjunction with the movable plate 7 fitted inside the cleaning frame 5, completes the relative dynamic seal of the cleaning frame 5. This allows the continuously blowing air to be ejected quickly from the through hole 15 on the bottom surface of the movable plate 7. Thus, when the solder coating is completed and the solder is cleaned, the airflow power of the upward blowing air completes the wind blowing of the battery's extreme points, cooling and dust removal, further improving the cleaning effect while ensuring that the battery to be soldered remains stable.

[0037] Second embodiment: When the cleaned positive and negative plates are transported to the welding lead pool 6 again, the electrode ends are placed downwards in the lead pool, and the welding lead pool 6 is started for group welding. After the welding is completed, as it is lifted up, the air supply component 13 is started again, and the control valve 132 is activated, so that the air pump 131 blows out along the side pipe 134 and into the interior of the purging component 14. The continuously supplied gas is input into each group of air outlet curved pipes 142 along the purging component 141, and blows along the upper end of the air outlet curved pipes 142 toward the welding point of the battery electrode group that has been removed from the welding lead pool 6. On the one hand, the attached lead water is removed, and on the other hand, the temperature is cooled down under continuous water sweeping.

[0038] First, by reusing the air supply assembly 13 and cooperating with the control valve 132 in the air supply assembly 13, after cleaning is completed, as the positive and negative plates of the battery complete the extreme electrode group welding, and as the battery plates move upward out of the welding lead pool 6 and are placed above, air is supplied to the purging assembly 14, so that the supplied air is blown along the air outlet curved pipe 142 towards the welding point of the battery plate electrode group, thereby achieving the purging of residual lead water and the purging of heat at the same time, achieving rapid cooling. Moreover, the power equipment used for actual cleaning and heat dissipation is shared, the arrangement of the cooling purging assembly 14 is simple, no additional power equipment is required, and the use effect is good.

[0039] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the mounting cylinder 121 is fixedly sleeved in the side of the cleaning frame 5, the rotating shaft 122 is rotatably sleeved inside the mounting cylinder 121, the gear 123 and the fan blade 124 are both fixedly sleeved on the outer surface of the rotating shaft 122, the gear 123 is meshed with the tooth 10, and the air outlet 125 is opened on the end face of the mounting cylinder 121 and is located inside the cleaning frame 5.

[0040] During use, the fan blades 124 in the mounting cylinder 121 are rotated by the input air volume, which in turn causes the shaft 122 to rotate. The air outlet 125 is used to blow out the input air, and the gas is blown upward in the cleaning frame 5.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the upright 91 is fixedly connected to the top surface of the movable plate 7, the inclined tube 92 is fixedly sleeved inside the upright 91, the movable plug 93 is movably sleeved in the inclined tube 92, the sliding rod 94 is movably sleeved in the inclined tube 92 and fixedly connected to the movable plug 93, and the ball 95 is located diagonally below the inclined tube 92 and fixedly connected to the sliding rod 94.

[0042] During use, the impact component 9 is used to complete the impact vibration, which improves the cleaning effect. At the same time, the inclined tube 92 is used to make the ball 95 fall naturally under gravity, which realizes the reserved movement length and ensures that it moves diagonally upward after impact, so that it can fall back under gravity on its own afterward.

[0043] like Figure 2 , Figure 3 and Figure 8 As shown, the air supply assembly 13 includes an air pump 131, a control valve 132, an intermediate pipe 133, and a side pipe 134. The air pump 131 is fixedly installed in the inner surface of the bottom frame 1. One end of the control valve 132 is fixedly connected to the outer end of the mounting cylinder 121. The intermediate pipe 133 is fixedly connected between the control valve 132 and the air pump 131. One end of the side pipe 134 is fixedly connected to one side of the control valve 132. The purging assembly 14 includes a distribution frame 141 and an outlet curved pipe 142. The distribution frame 141 is fixedly connected to the side of the welding lead pool 6. The outlet curved pipe 142 is fixedly connected to the top of the distribution frame 141. The side of the distribution frame 141 is fixedly connected to the other end of the side pipe 134.

[0044] During use, air is input through the air supply component 13 and the direction of the control valve 132 is switched. On the one hand, when the gas is input into the rotating component 12, the rotating shaft 122 is driven to rotate. On the other hand, the output gas is used to blow the upward battery electrode plate through the through hole 15. At the same time, the direction of air supply is switched to cool and clean the welded joint of the battery electrode group after welding.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the bottom surface of the bottom frame 1 is provided with an adapter groove 16, the inner surface of the adapter groove 16 is fixedly connected to the mounting cylinder 121, the side of the bottom frame 1 is provided with a convex groove 17, the top of the bottom frame 1 is provided with a sliding groove 18, the bottom surface of the movable plate 7 is fixedly connected with a side plate 20, the side of the side plate 20 is fixedly connected with a spring 21, the inner surface of the convex groove 17 is adapted to the structure of the movable plate 7 and the sponge layer 8, the inner surface of the convex groove 17 is movably sleeved with the movable plate 7 and the sponge layer 8, the sliding groove 18 is movably sleeved with the impact component 9, the two sides of the sponge layer 8 are provided with side grooves 19, the side grooves 19 are located outside the impact component 9, the bottom surface of the movable plate 7 is provided with a through hole 15, the bottom surface of the cleaning frame 5 is provided with a bottom groove 11, the bottom groove 11 is adapted to the structural shape of the mounting cylinder 121, the top frame 2 is fixedly installed on the top of the bottom frame 1, the clamping part 3 is located above the solder pool 4, the clamping part 3 is slidably connected to the top of the inner surface of the top frame 2.

[0046] During use, the convex groove 17 is adapted to the movable plate 7 and the sponge layer 8 to maintain the lateral stable movement of the movable plate 7. The side groove 19 is adapted to the lateral movement of the impact component 9. The through hole 15 is used to move the introduced gas upward and complete the pre-stage purging. The clamping part 3 is an existing structure used to clamp the battery plates to realize transportation.

[0047] Working principle and usage process: When soldering is required, the positive and negative plates of the lead-acid battery are installed alternately, causing the clamping part 3 in the top frame 2 to move laterally and lower, clamping the stacked positive and negative plates together. Then, the clamping part 3 moves and sends the positive and negative electrodes to the top of the solder pool 4. The positive and negative electrodes are lowered so that the electrode ends are placed in the solder pool 4 to complete the solder coating. The positive and negative electrodes are moved upward to remove them and moved to the top of the cleaning frame 5. The positive and negative electrode plates are lowered again, and the air supply component 13 is started, so that the air pump 131 delivers gas through the control valve 132 to the rotating component 12. With the high-pressure air supply delivered to the rotating component 12... In the mounting cylinder 121 of component 12, high-pressure air drives the fan blade 124 to rotate, causing the shaft 122 to rotate. As the fan blade 124 rotates, the gas is blown out along the through hole 15. At the same time, the shaft 122 drives the gear 123 to rotate, causing the gear 123 to drive the movable plate 7 to move laterally through the meshing teeth 10. This causes the movable plate 7 to drive the sponge layer 8 to move laterally. The sponge layer 8 moves laterally and comes into contact with the extreme ends of the tin-coated battery, rubbing away the molten solder adhering to the surface. At the same time, the laterally moving movable plate 7 causes the impact component 9 on one side to move laterally, causing the downward-sloping impact ball 95 to move quickly and collide with the clamping part. On one side of 3, the clamping part 3 and the clamped positive and negative plates vibrate simultaneously, causing the molten solder and dust adhering to the surface to vibrate and detach quickly. At the same time, one side of the spring 21 is compressed while the other side of the spring 21 is stretched. When the air supply is cut off, the spring 21 elastically resets and drives the movable plate 7 to reset. Under inertia, the impact component 9 on the other side quickly impacts the clamping part 3 on the other side, completing a thorough cleaning and liquid removal. The gas blown into the cleaning frame 5 is blown upward quickly through the through hole 15 on the bottom surface of the movable plate 7 and blown upward along the bottom of multiple sets of positive and negative plates. When the cleaned positive and negative plates are transported again... The electrode is placed downwards into the lead pool 6 and the welding lead pool 6 is started for group welding. After the welding is completed, the gas supply component 13 is started again as the electrode is lifted up. At the same time, the control valve 132 is activated, so that the air pump 131 blows out along the side pipe 134 and into the interior of the purging component 14. The continuously supplied gas is input into each group of air outlet curved pipes 142 along the purging component 141 and blows along the upper end of the air outlet curved pipes 142 toward the welding point of the battery electrode group that has been removed from the welding lead pool 6. This removes the attached lead water and cools down the battery under continuous water purging.
