Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery cross-bridge welding technology, and in particular to a multi-directional linkage multi-point synchronous clamping and welding mechanism. Background Technology

[0002] In the field of lead-acid batteries, the use of cross-bridge welding between individual cells in batteries with a voltage of 4V and above is a common series connection method. Cross-bridge welding refers to welding multiple individual electrodes in series through conductors to increase the total voltage of the battery pack.

[0003] The existing bridge welding method uses welding clamps to hold the two butt welding parts to be welded to achieve welding between the two butt welding parts, and the clamping direction of the welding clamps is on both sides of the welding position of the two butt welding parts.

[0004] Because the individual cells in a lead-acid battery are located in different positions, the distribution direction of the welding and series connection points between adjacent cells is also different. Therefore, the industry needs to use welding clamps to clamp the welding parts one by one from multiple directions for welding and series connection. This is inefficient and poses a risk of lead leakage due to the welding clamps not clamping tightly.

[0005] To solve the above problems, there is an urgent need for a multi-directional linkage and multi-point synchronous clamping and welding mechanism. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-directional linkage multi-point synchronous clamping and welding mechanism to solve the problem mentioned in the background art that the existing cross-bridge welding clamping mechanism can only clamp the cross-bridge welding points in different directions one by one when clamping each cross-bridge welding point in a lead-acid battery, which reduces the efficiency of cross-bridge welding.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional linkage multi-point synchronous clamping and welding mechanism, including a welding mold body, the top of the welding mold body is provided with multiple welding holes, the number and position of the welding holes are designed according to the position of the welding parts on the battery to be cross-bridge welded, the top of the welding mold body is symmetrically provided with two vertical holes, and a clamping component is connected to the welding mold body;

[0008] The clamping assembly is used to clamp the two butt welds in each butt weld hole within the hole wall.

[0009] Preferably, the clamping assembly includes a pushing mechanism connected to the welding mold body, and further includes several transverse limiting grooves formed on the welding mold body. Several transverse ejector pins are connected to the pushing mechanism, and these transverse ejector pins pass through transverse ejector pin through holes on the side of the welding mold body and are movably inserted into the several transverse limiting grooves. The clamping assembly also includes two sets of longitudinal limiting grooves formed on the welding mold body, the two sets of longitudinal limiting grooves being distributed front to back, and several transverse limiting grooves located between the two sets of longitudinal limiting grooves. Two sets of longitudinal ejector pins are symmetrically connected to the pushing mechanism, and these two sets of longitudinal ejector pins pass through longitudinal ejector pin through holes on the side of the welding mold body and are movably inserted into the two sets of longitudinal limiting grooves. The longitudinal limiting grooves and transverse limiting grooves respectively pass through multiple welding holes and are located in the middle of the welding holes. The transverse and longitudinal ejector pins are made of heat-resistant material. The advantage of this arrangement is that the pushing mechanism, in conjunction with the transverse and longitudinal limiting grooves, pushes the transverse and longitudinal ejector pins into their corresponding positions. Inside the welding hole, the two welding components located within it can be pushed open to both sides and pressed tightly against the hole wall, thus clamping them together. This ensures a stable and consistent gap between the two welding components, guaranteeing the welding quality and reliability. Simultaneously, the lateral and longitudinal ejector pins can clamp welding components distributed in different directions, allowing for the simultaneous clamping of all welding components on a lead-acid battery. This avoids inconsistent clamping force caused by individually clamping each welding point with welding pliers, improving welding efficiency and quality. Furthermore, the lateral and longitudinal ejector pins act as a barrier between the two welding components, and their heat-resistant material effectively prevents molten lead from leaking into the battery compartment through the gap between the two welding components during welding. This prevents lead loss at the welding point due to molten lead leakage, resulting in insufficient cross-sectional area and improving welding quality and effectiveness.

[0010] Preferably, the pushing mechanism includes a cylinder fixedly connected to the right side of the welding mold body via a fixing frame. A main connecting plate is fixedly connected to the output end of the cylinder. Two pairs of auxiliary connecting plates are symmetrically hinged to the front and rear ends of the main connecting plate via first pins. Two main connecting rods are symmetrically hinged between the ends of the two pairs of auxiliary connecting plates away from the main connecting plate via second pins. The pushing mechanism also includes two auxiliary connecting rods. Two rectangular slots are symmetrically formed on the opposite sides of the two auxiliary connecting rods. Two third pins are symmetrically fixedly connected between the inner top and bottom walls of the two rectangular slots. The two auxiliary connecting rods are located away from the main connecting plate. One end of each rod is hinged to two third pins. Several transverse ejector pins are fixedly connected to the left side of the main connecting plate. Two sets of longitudinal ejector pins are fixedly connected to the adjacent sides of two auxiliary connecting rods. Two movable cavities are symmetrically opened on the top of the welding mold body. Two pairs of first guide rods are symmetrically fixedly connected between the inner walls of the two movable cavities. Two auxiliary connecting rods are symmetrically and movably sleeved on the outer circumferential surfaces of the two pairs of first guide rods. Two second guide rods are symmetrically and fixedly connected to the right side of the welding mold body. The main connecting plate is movably sleeved between the outer circumferential surfaces of the two second guide rods. The front and rear of the welding mold body... Two first through slots are symmetrically formed on the side, each connecting to one of the two movable cavities. Two second through slots are symmetrically formed on the top of the welding mold body, with the bottom ends of both slots penetrating the bottom surface of the welding mold body and passing through the two first through slots respectively. Two second pins are symmetrically slidably connected within the two second through slots. Two main connecting rods are movably inserted into the two first through slots. The advantage of this design is that by simply activating the cylinder and cooperating with the second guide rod to push the main connecting plate to the left, the main connecting plate can then cooperate with the transverse limiting slots to push several transverse ejector pins into corresponding positions. The corresponding weld joints are clamped in the welding holes. The main connecting plate, in conjunction with the second pin and the second through groove, pushes the two pairs of auxiliary connecting plates to the left. At this time, due to the limiting of the auxiliary connecting rod by the first guide rod, the main connecting rod rotates along the first through groove, thereby pushing the two auxiliary connecting rods to move towards each other. In this way, in conjunction with the longitudinal limiting groove, the two sets of longitudinal ejector pins are pushed into the two sets of welding holes to complete the clamping operation of the corresponding weld joints. This allows the clamping operation of the weld joints at all welding points to be completed at one time, thereby improving the clamping efficiency of the weld joints and thus greatly improving the efficiency of the bridge welding process.

[0011] Preferably, both the transverse limiting groove and the longitudinal limiting groove are formed on the bottom surface of the welding mold body. The advantage of this arrangement is that it allows the transverse ejector pin or the longitudinal ejector pin to clamp the weldment to a greater depth, thereby ensuring the welding thickness between the weldment parts, increasing the cross-sectional area of ​​the bridge welding, and improving the quality of the bridge welding.

[0012] Preferably, the top of the welding mold body is provided with multiple anti-overflow recesses, and the multiple anti-overflow recesses are coaxially connected to the top of multiple welding holes and are located directly above the multiple welding holes. The advantage of this arrangement is that it can prevent the molten lead generated during welding from overflowing from the welding holes and flowing onto the surface of the welding mold body, thereby reducing the loss of molten lead and further improving the thickness and strength of the welded part between the welding parts.

[0013] Preferably, the diameter of the welding hole decreases uniformly from bottom to top. This design ensures that the weldment is reliably pressed against the wall of the welding hole by the pushing action of the transverse or longitudinal ejector pin, thus ensuring the clamping firmness of the weldment and the quality and effect of the bridge welding.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, the welding mold body is provided with corresponding welding holes on the top of the welding mold body according to the distribution position and direction of the welding parts on the lead-acid battery to be bridged and welded. At the same time, with the clamping component, the welding parts of multiple welding points can be clamped at one time. Compared with using welding clamps to clamp the welding parts on each welding point in turn, the efficiency of bridged welding is effectively improved. At the same time, it can avoid the problem of inconsistent welding quality caused by the inconsistent clamping force of clamping the welding parts on multiple welding points separately, thus improving the welding quality and effect of bridged welding.

[0016] 2. In this utility model, the clamping components allow the transverse and longitudinal ejector pins to clamp the weldment while simultaneously blocking the gap between the two weldment parts in each weld hole. Furthermore, the transverse and longitudinal ejector pins are made of heat-resistant material, which effectively prevents the molten lead generated during welding from leaking into the battery box of the storage battery through the gap between the two weldment parts. This avoids the loss of lead material at the welding part due to lead leakage, resulting in insufficient cross-sectional area and improving the quality and effect of welding.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1-7 The multi-directional linkage multi-point synchronous clamping and welding mechanism shown includes a welding mold body 1. The top of the welding mold body 1 is provided with multiple welding holes 2. The number and position of the welding holes 2 are designed according to the position of the welding parts 61 on the battery to be welded across the bridge. Two vertical holes 3 are symmetrically opened on the top of the welding mold body 1. A clamping assembly 4 is connected to the welding mold body 1.

[0028] The clamping assembly 4 is used to clamp the two butt weld parts 61 in each butt weld hole 2 within the hole wall of the butt weld hole 2.

[0029] refer to Figure 1 and Figure 2The clamping assembly 4 includes a pushing mechanism 41 connected to the welding mold body 1. The clamping assembly 4 also includes several transverse limiting grooves 42 opened on the welding mold body 1. Several transverse ejector pins 43 are connected to the pushing mechanism 41. The several transverse ejector pins 43 pass through the transverse ejector pin through holes on the side of the welding mold body 1 and are movably inserted into the several transverse limiting grooves 42 respectively. The clamping assembly 4 also includes two sets of longitudinal limiting grooves 44 opened on the welding mold body 1. The two sets of longitudinal limiting grooves 44 are distributed front and back. Several transverse limiting grooves 42 are located between the two sets of longitudinal limiting grooves 44. Two sets of longitudinal ejector pins 45 are symmetrically connected to the pushing mechanism 41. The two sets of longitudinal ejector pins 45 pass through the longitudinal ejector pin through holes on the side of the welding mold body 1 and are movably inserted into the two sets of longitudinal limiting grooves 44 respectively. The longitudinal limiting grooves 44 and the transverse limiting grooves 42 pass through multiple welding holes 2 and are located in the middle position of the welding holes 2. The transverse ejector pins 43 and the longitudinal ejector pins 45 are made of heat-resistant material.

[0030] Specifically, by using the pushing mechanism 41 in conjunction with the transverse limiting groove 42 and the longitudinal limiting groove 44, the transverse ejector pin 43 and the longitudinal ejector pin 45 are respectively pushed into the corresponding welding holes 2. This pushes the two welding parts 61 located in the welding holes 2 to both sides and tightly abuts against the hole wall of the welding hole 2, thus clamping the two welding parts 61. This ensures that the distance between the two welding parts 61 is stable and consistent, thereby ensuring the welding quality and reliability of the welding parts 61. At the same time, the transverse ejector pin 43 and the longitudinal ejector pin 45 can clamp the welding parts 61 in different distribution directions. In this way, all welding parts 61 on a lead-acid battery 6 can be clamped at once. The clamping operation of the weldment 61 avoids the inconsistent clamping force caused by individually clamping each weldment 61 at each welding point with welding pliers, thereby improving the efficiency and quality of welding. Furthermore, the transverse ejector pin 43 and the longitudinal ejector pin 45 can block the gap between the two weldment 61s. The transverse ejector pin 43 and the longitudinal ejector pin 45 are made of heat-resistant material, which can effectively prevent the molten lead generated by the weldment 61 from leaking into the battery box of the storage battery through the gap between the two weldment 61s during welding. This avoids the loss of lead material at the welding part due to lead leakage, resulting in insufficient cross-sectional area and improving the quality and effect of welding.

[0031] refer to Figures 2-7The pushing mechanism 41 includes a cylinder 411 fixedly connected to the right side of the welding mold body 1 via a fixing frame 11. A main connecting plate 412 is fixedly connected to the output end of the cylinder 411. Two pairs of auxiliary connecting plates 413 are symmetrically hinged to the front and rear ends of the main connecting plate 412 via first pins. Two main connecting rods 415 are symmetrically hinged between the ends of the two pairs of auxiliary connecting plates 413 away from the main connecting plate 412 via second pins 414. The pushing mechanism 41 also includes two auxiliary connecting rods 416. Two rectangular grooves 417 are symmetrically formed on the sides of the two auxiliary connecting rods 416 away from each other. Two third pins are symmetrically fixedly connected between the inner top and inner bottom walls of the two rectangular grooves 417. The ends of the two auxiliary connecting rods 416 away from the main connecting rods 415 are respectively hinged to the two third pins. Several transverse ejector pins 43 are fixedly connected to the left side of the main connecting plate 412. Two sets of longitudinal ejector pins 45 are respectively fixedly connected to the two auxiliary connecting rods 416. On the six adjacent sides, two movable cavities 12 are symmetrically opened on the top of the welding mold body 1. Two pairs of first guide rods 121 are symmetrically fixedly connected between the inner sidewalls of the two movable cavities 12. Two auxiliary connecting rods 416 are symmetrically and movably sleeved on the outer circumferential surfaces of the two pairs of first guide rods 121. Two second guide rods 122 are symmetrically and fixedly connected on the right side of the welding mold body 1. The main connecting plate 412 is movably sleeved between the outer circumferential surfaces of the two second guide rods 122. Two first through slots 13 are symmetrically opened on the front and rear sides of the welding mold body 1. The two first through slots 13 are respectively connected to the two movable cavities 12. Two second through slots 14 are symmetrically opened on the top of the welding mold body 1. The bottom ends of the two second through slots 14 penetrate the bottom surface of the welding mold body 1 and penetrate the two first through slots 13 respectively. Two second pins 414 are symmetrically and slidably connected in the two second through slots 14. Two main connecting rods 415 are respectively movably inserted into the two first through slots 13.

[0032] Specifically, by simply activating cylinder 411 and cooperating with second guide rod 122 to push main connecting plate 412 to the left, main connecting plate 412 can cooperate with transverse limiting groove 42 to push several transverse ejector pins 43 into several corresponding butt welding holes 2 to clamp the corresponding butt welding parts 61. Main connecting plate 412 can then cooperate with second pin 414 and second through groove 14 to push two pairs of auxiliary connecting plates 413 to the left. At this time, due to the limiting of auxiliary connecting rod 416 by first guide rod 121, main connecting rod 415 rotates along first through groove 13, thereby pushing two auxiliary connecting rods 416 to move in the same direction. In this way, it can cooperate with longitudinal limiting groove 44 to push two sets of longitudinal ejector pins 45 into two sets of butt welding holes 2 to complete the clamping operation of corresponding butt welding parts 61. This allows the clamping operation of butt welding parts 61 at all butt welding points to be completed at one time, thereby improving the clamping efficiency of butt welding parts 61 and thus greatly improving the efficiency of bridge butt welding processing.

[0033] refer to Figure 2Both the transverse limiting groove 42 and the longitudinal limiting groove 44 are opened on the bottom surface of the welding mold body 1.

[0034] Specifically, the horizontal ejector pin 43 or the vertical ejector pin 45 can clamp the butt weld 61 to a greater depth, thereby ensuring the welding thickness between the butt welds 61, increasing the cross-sectional area of ​​the bridge weld and improving the quality of the bridge weld.

[0035] refer to Figure 1 , Figure 3 and Figure 5 The top of the welding mold body 1 is provided with multiple anti-overflow pits 5, and the multiple anti-overflow pits 5 are coaxially connected to the top of multiple welding holes 2 and are located directly above the multiple welding holes 2.

[0036] Specifically, it can prevent the molten lead generated during welding of the weldment 61 from overflowing from the weld hole 2 and flowing onto the surface of the weld mold body 1, thereby reducing the loss of molten lead and further improving the thickness and strength of the welded part between the weldment 61.

[0037] refer to Figure 6 and Figure 7 The diameter of the weld hole 2 decreases uniformly from bottom to top.

[0038] Specifically, the action of the transverse ejector pin 43 or the longitudinal ejector pin 45 ensures that the weldment 61 is reliably pressed against the wall of the weld hole 2, thereby ensuring the clamping firmness of the weldment 61 and thus ensuring the quality and effect of the bridge welding.

[0039] Working principle: Align the multiple welding holes 2 with the welding parts 61 at each welding point on the lead-acid battery 6 to be welded, and at the same time align the two vertical holes 3 with the two terminals on the lead-acid battery 6 respectively. Then push the welding mechanism downward until the multiple welding holes 2 are completely fitted onto the multiple welding parts 61.

[0040] Then, the cylinder 411 is activated to push the main connecting plate 412 to the left. At this time, the main connecting plate 412 can cooperate with the transverse limiting groove 42 to push several transverse ejector pins 43 to insert into several corresponding welding holes 2 to clamp the corresponding welding parts 61. The main connecting plate 412 can cooperate with the second pin 414 and the second through groove 14 to push two pairs of auxiliary connecting plates 413 to the left. At this time, due to the limiting of the auxiliary connecting rod 416 by the first guide rod 121, the main connecting rod 415 rotates along the first through groove 13, thereby pushing the two auxiliary connecting rods 416 to move towards each other. In this way, it can cooperate with the longitudinal limiting groove 44 to push two sets of longitudinal ejector pins 45 to insert into two sets of welding holes 2 to complete the clamping operation of the corresponding welding parts 61, so that the clamping operation of the welding parts 61 at all welding points can be completed at one time.

[0041] Subsequently, the welding gun is used to weld the two welding parts 61 in each anti-overflow pit 5 on the top surface of the welding mold body 1. Due to the deep clamping thickness of the transverse ejector pin 43 and the longitudinal ejector pin 45 and the sufficient heat resistance of the transverse ejector pin 43 and the longitudinal ejector pin 45, the molten lead liquid of the welding parts 61 will not leak during welding, thus ensuring the welding thickness of the welding part 61.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
