Abstract
Description
Technical Field
[0001] This utility model relates to the field of lead-acid battery production technology, specifically to a lead-acid battery electrode group loading device. Background Technology
[0002] In the manufacturing process of lead-acid batteries, from the assembly of electrode plates to the final installation into the battery box before casting and welding, the processing is carried out in units of electrode groups, which are configured and connected in series according to capacity. An electrode group consists of several groups of positive and negative electrode plates and separators between the positive and negative electrode plates. Each electrode plate has a tab. In each electrode group, the tabs of all positive electrode plates are located on one side of the top surface of the electrode group, and the tabs of all negative electrode plates are located on the other side of the top surface of the electrode group. The tabs of the same electrode are connected in series with the busbar by casting and welding.
[0003] In existing technologies, the electrode group is usually fixed in the casting and welding fixture first, and then the busbar is cast and welded. After the casting and welding is completed, the electrode group is pressed into the battery box. This process is called electrode group insertion.
[0004] Chinese utility model patent with authorization announcement number CN202004112U discloses a manual slotting device for a group of equipment, including a bracket, a handle, a pressure rod, a loading and unloading block, and a pressure block. One end of the handle is rotatably connected to the bracket, the upper end of the pressure rod is slidably connected to the handle, the pressure rod passes through the upper crossbeam of the bracket, the lower end of the pressure rod is connected to the loading and unloading block, and the loading and unloading block is provided with at least one pressure block.
[0005] Chinese utility model patent CN206301907U discloses a battery terminal group inlet device with buffer function, including a vertically liftable base. The bottom surface of the base is provided with multiple top blocks. Each top block includes a base and a buffer part. The buffer part is connected to the base through a guide rod, and a buffer spring is sleeved on the guide rod.
[0006] The aforementioned existing technologies are all for conventional battery structures, and the electrode group inlet device has a relatively simple structure.
[0007] Patent document CN209029499U discloses a lead-acid battery casting and welding machine, including an electrode group insertion mechanism. The electrode group insertion mechanism includes top columns that push the electrode group into the battery cell, and a base plate supporting the top columns. The key feature is that a buffer spring is provided between the base plate and each top column. All top columns are movably mounted on a limiting plate, and a positioning column is fixed to the base plate, vertically passing through the limiting plate to fix it in place. The buffer spring between the base plate and the top columns of the electrode group insertion mechanism acts as a buffer during the process of the top columns pushing the electrode group into the battery cell, preventing damage to the busbar and electrode tabs from instantaneous impact. However, in this technical solution, the top columns constantly apply pressure to the busbar in contact with them during the electrode group insertion process, which can easily damage the busbar during the process of squeezing the electrode group into the cell. Utility Model Content
[0008] The main purpose of this utility model is to provide a lead-acid battery electrode group inlet device that allows the push rod to avoid deformed busbars and ensures that the push rod always applies force to squeeze the upper end of the electrode group.
[0009] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0010] A lead-acid battery electrode group loading device includes a base plate. A clamping unit is slidably disposed on the upper end of the base plate to clamp the electrode group before loading. A top-loading unit is disposed above the clamping unit and is connected to a drive unit. The drive unit can drive the top-loading unit to move vertically. The top-loading unit includes an upper plate. Side plates are fixed on both the front and rear sides of the lower end of the upper plate. Multiple top-loading components are installed between the side plates. The multiple top-loading components are evenly distributed in the transverse direction between the side plates. Each top-loading component includes a fixing rod fixed between the side plates. The fixing rod is longitudinally arranged and multiple top rods are slidably disposed on the fixing rod. Multiple universal balls are fixed on the upper end of each top rod. The universal balls are in rolling contact with the lower end of the upper plate. Adjacent top rods are elastically connected. The side plate is elastically connected to the top rod on one side. The top rods of two adjacent top-loading components are arranged correspondingly on the left and right. The gaps between the multiple top rods form a busbar clearance groove. Guide slopes are machined on both the front and rear sides of the lower end of the top rods.
[0011] Specifically, the two adjacent top rods are connected by an upper spring, and the side plate is connected to the top rod on one side by an upper spring.
[0012] Specifically, the clamping unit includes two symmetrically arranged sliding plates, which are slidably mounted on the upper part of a base plate. A power component capable of driving the sliding plates to move in the longitudinal direction is provided on the base plate. An inner plate is fixed between the two sliding plates, and multiple clamping members pass through the inner plate. The clamping members are slidably connected to the inner plate. The number of clamping members is the same as the number of pole groups to be inserted. A drive assembly is provided between the two sliding plates, which can simultaneously drive the multiple clamping members to move and clamp the multiple pole groups simultaneously.
[0013] Specifically, the lower end of the slide plate is slidably connected to the slide rail, and the slide rail is fixed to the base plate.
[0014] Specifically, the power assembly includes two longitudinally arranged telescopic rods, which are fixedly connected to the base plate. Ear plates are fixed to the telescopic ends of the telescopic rods, and the ear plates are fixedly connected to a sliding plate on one side of the rods.
[0015] Specifically, the clamping member includes two clamping plates, with an inner plate passing through the clamping plates and the inner plate slidably connected to the clamping plates. The two clamping plates of the clamping member are connected by a lower spring.
[0016] Specifically, the drive assembly includes a rotating rod rotatably disposed between two sliding plates. A motor is fixed on one of the sliding plates, and the output shaft of the motor is concentrically fixedly connected to the rotating rod. The rotating rod passes through the clamping plate. Rotary sleeves are concentrically fitted and fixed on the rotating rods on both sides of the clamping member. Arc-shaped protrusions are fixed at the opposite ends of the rotating sleeves on both sides of the clamping member. The arc-shaped protrusions are located on the outside of the clamping plate. After the rotating sleeves and arc-shaped protrusions on both sides of the clamping member rotate, the arc-shaped protrusions on both sides can squeeze the two clamping plates of the clamping member closer to each other.
[0017] Specifically, a limiting plate is fixed to the upper end of the base plate between the two slide plates.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. The push rod is laterally elastically connected by an upper spring, and in conjunction with the rolling contact between the universal ball and the upper plate, it allows the push rod to slide laterally along the fixed rod under pressure, adaptively avoiding deformed busbars and preventing direct pressure from the push rod causing the electrode lugs to detach from the busbars. The lower end of the push rod is machined with front and rear guide bevels to guide the push rod to shift laterally when the electrode group enters the slot, further reducing the risk of compression damage to the busbars. The gaps between adjacent push rods naturally create clearance space for the busbars, ensuring that the push rods only apply force to the electrode group body and avoid contact with the fragile busbar structure.
[0020] 2. Through the coordinated design of the rotating rod, rotating sleeve, and arc-shaped protrusion, the drive assembly can simultaneously control the opening and closing of the clamping plates of multiple clamping components, achieving rapid synchronous clamping or release of multiple pole groups and improving batch operation efficiency. The clamping plates are connected by a lower spring, providing flexible pressure during clamping to prevent deformation or surface damage to the pole groups caused by rigid clamping. The lower spring enables the clamping plates to quickly return to their original position.
[0021] 3. The slide plate achieves precise forward and backward movement through guide rails and telescopic rods. The clamping unit can quickly disengage after the electrode group is inserted into the slot, avoiding interference with the subsequent actions of the insertion unit. The battery casing is limited by a limiting plate that cooperates with the slide plate to ensure that the electrode group is strictly aligned with the battery casing slot when it is inserted into the slot, reducing assembly failures caused by misalignment.
[0022] 4. Both the top-entry assembly and the clamping components adopt a horizontally evenly distributed layout, adaptable to different sizes of electrode groups and battery cases, with strong expandability. The elastic connection of the top-entry unit and the rigid limiting of the clamping unit complement each other, protecting the integrity of the electrode group structure while ensuring a stable and efficient insertion process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Example 1: Refer to Figures 1-4 As shown, a lead-acid battery electrode group loading device includes a base plate 1, and a clamping unit that can clamp the electrode group 21 before it is loaded into the slot is slidably disposed on the upper end of the base plate 1.
[0030] A top-feeding unit is provided above the clamping unit. The top-feeding unit is connected to the driving unit, which can drive the top-feeding unit to move in the vertical direction.
[0031] The top-in unit includes an upper plate 14, and side plates 15 are fixed on both the front and rear sides of the lower end of the upper plate 14. Multiple top-in components are installed between the two side plates 15, and the multiple top-in components are evenly distributed in the lateral direction between the two side plates 15.
[0032] The insertion assembly includes a fixing rod 18 fixed between two side plates 15. The fixing rod 18 is arranged longitudinally, and multiple push rods 16 are slidably arranged on the fixing rod 18. Multiple universal balls 20 are fixed to the upper end of each push rod 16. The universal balls 20 are in rolling contact with the lower end of the upper plate 14. Adjacent push rods 16 are connected by upper springs 19. The side plates 15 are connected to the push rods 16 on one side by upper springs 19. The push rods 16 of two adjacent insertion assemblies are arranged symmetrically on the left and right sides, and the gaps between the multiple push rods 16 form the clearance grooves of the manifold 11.
[0033] Guide slopes 17 are machined on both the front and rear sides of the lower end of the push rod 16.
[0034] The clamping unit includes two symmetrically arranged sliding plates 5, which are slidably mounted on the upper part of the base plate 1. Specifically, the lower end of the sliding plate 5 is slidably connected to the slide rail 2, which is fixed to the base plate 1.
[0035] The base plate 1 is equipped with a power component that can drive the skateboard 5 to move in the longitudinal direction. Specifically, the power component includes two longitudinally arranged telescopic rods 3, which are fixedly connected to the base plate 1. The telescopic ends of the telescopic rods 3 are fixed with ear plates 4, which are fixedly connected to the skateboard 5 on one side.
[0036] An inner plate 6 is fixed between two sliding plates 5. Multiple clamping members pass through the inner plate 6. The clamping members are slidably connected to the inner plate 6. The number of clamping members is the same as the number of pole groups 21 to be inserted. A drive assembly is provided between the two sliding plates 5. The drive assembly can simultaneously drive the multiple clamping members to move and clamp the multiple pole groups 21 at the same time.
[0037] The clamping component includes two clamping plates 9, with an inner plate 6 passing through the clamping plates 9. The inner plate 6 is slidably connected to the clamping plates 9, and the two clamping plates 9 are connected by a lower spring 10. The drive assembly includes a rotating rod 7 rotatably disposed between two sliding plates 5. A motor 8 is fixed on one of the sliding plates 5, and the output shaft of the motor 8 is concentrically fixedly connected to the rotating rod 7. The rotating rod 7 passes through the clamping plates 9, and rotating sleeves 12 are concentrically fitted and fixed on the rotating rods 7 on both sides of the clamping component. Arc-shaped protrusions 13 are fixed at opposite ends of the rotating sleeves 12 on both sides of the clamping component. The arc-shaped protrusions 13 are located on the outside of the clamping plates 9. After the rotating sleeves 12 and arc-shaped protrusions 13 on both sides of the clamping component rotate, the arc-shaped protrusions 13 on both sides can squeeze the two clamping plates 9 of the clamping component closer to each other.
[0038] When the electrode group 21 is inserted, the lower ends of the multiple electrode groups 21 are placed between the two clamping plates 9 of the clamping member, so that the electrode group 21 is tightly against the inner plate 6. The motor 8 is started, and the motor 8 drives the rotating rod 7, the rotating sleeve 12 and the arc-shaped protrusion 13 to rotate. When the distal end of the arc-shaped protrusion 13 is tightly against the clamping plate 9, the two clamping plates 9 of the clamping member clamp the lower ends of the electrode group 21, place the battery case on the base plate 1, and make the slot of the battery case correspond to the electrode group 21.
[0039] Then the drive unit is activated, and the drive unit drives the push-in unit to move downward. The lower end of the push rod 16 presses against the upper end of the electrode group 21 and then squeezes the electrode group 21 downward. Since the clamping member clamps the electrode group 21, the thickness of the electrode group 21 is reduced. Therefore, when the push rod 16 moves downward and squeezes the electrode group 21 downward, the lower end of the electrode group 21 can easily enter the slot of the battery case.
[0040] After the lower end of electrode group 21 enters the slot of the battery case, motor 8 is started. Motor 8 drives rotating rod 7, rotating sleeve 12 and arc-shaped protrusion 13 to rotate. When arc-shaped protrusion 13 separates from clamping plate 9 and rotates to the outside of clamping plate 9, the two clamping plates 9 of the clamping member are reset under the elastic force of lower spring 10. Then, telescopic rod 3 is activated, causing the clamping unit to move forward and misalign with battery case and electrode group 21. Then, the drive unit drives the push-in unit to continue downward, and push rod 16 continues to press electrode group 21 downward until electrode group 21 is completely inserted into the slot of battery case.
[0041] When the push rod 16 descends and presses against the upper end of the electrode group 21, and when the push rod 16 contacts the deformed busbar 11, under the guidance of the guide ramp 17, the push rod 16 can move along the axial direction of the fixed rod 18. At the same time, the upper spring 19 connected to the push rod 16 moving on the fixed rod 18 deforms. After the push rod 16 is displaced, it can offset the deformed busbar 11, which can prevent the push rod 16 from exerting force on the busbar 11 and prevent the deformation of the busbar 11 from causing the electrode tab to detach from the busbar 11.
[0042] Example 2: Based on Example 1, referring to... Figure 1 As shown, a limiting plate 22 is fixed to the upper end of the base plate 1 between the two slide plates 5.
[0043] In this embodiment, the limiting plate 22 and the two sliding plates 5 cooperate to limit the battery case. The battery case is located on the upper end of the base plate 1 and its rear end abuts against the front end of the limiting plate 22. The left and right ends of the battery case are in contact with the two sliding plates 5 respectively. At this time, the battery case is limited, which can ensure that the electrode group 21 is accurately inserted into the slot.
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
