Description

Technical Field

[0001] This utility model relates to a lead-acid battery stacking mechanism, belonging to the field of lead-acid battery manufacturing technology. Background Technology

[0002] In the manufacturing process of lead-acid batteries, the positive electrode plate is wrapped with a separator and stacked with the negative electrode plate to form an electrode group. After multiple electrode groups are stacked, a side negative plate is stacked outside the outermost positive electrode plate to form an electrode group. To improve efficiency and save space, a disc-type stacking machine is generally used to stack the electrode groups. However, in the current conventional stacking method, the side negative plate, like the positive and negative electrode plates, enters the disc-type stacking machine at the front end of the production line and is rotated and stacked to form the electrode group. In this structure, because the side negative plate is sent to the disc-type stacking machine separately, a larger rotation angle is required to complete one electrode group stacking, resulting in lower efficiency. Utility Model Content

[0003] This invention addresses the problem of low lamination efficiency in the current production process of lead-acid batteries by proposing a lamination mechanism for lead-acid batteries. After all the positive and negative plates are stacked, the negative plate is inserted into the positive plate, thereby improving production efficiency.

[0004] The technical means adopted by this utility model to solve the above problems is as follows: a lead-acid battery stacking mechanism, including a disc-type stacking machine for stacking positive and negative plates into electrode groups, a stacking device with one end set at the discharge port of the disc-type stacking machine for stacking side negative plates and electrode groups into electrode groups, and a feeding device set on the side of the stacking device for transporting side negative plates to the stacking device. The stacking device includes a conveyor chain and a conveyor table arranged in upper and lower layers. The inlet of the conveyor chain is connected to the discharge port of the disc-type stacking machine, and the conveyor table is connected to the feeding device. The feeding direction of the side negative plates and electrode groups is perpendicular, improving the stacking speed of the electrode groups.

[0005] Furthermore, both the conveyor chain and the conveyor table have a gap in the middle. The electrode plate group overlaps on both sides of the gap in the conveyor chain, and the side negative plate overlaps on both sides of the conveyor plate. The stacking device also includes a push rod that moves along the gap between the conveyor chain and the conveyor plate to push the electrode plate forward. The push rod pushes the electrode plate group and the side negative plate out of the stacking device simultaneously and stacks them into an electrode group.

[0006] Furthermore, the feeding device includes a support plate for placing the side negative plate and a push plate for pushing the side negative plate on the support plate into the conveyor table, wherein the support plate is connected to the conveyor table and the height of the support plate is flush with the height of the conveyor table.

[0007] Furthermore, the support plate is provided with multiple through slots, and multiple push plates pass through the multiple through slots from bottom to top to push the side negative plate forward.

[0008] Furthermore, the feeding device also includes a fixed plate, a movable plate, and a feeding motor. The fixed plate is fixed relative to the support plate. The feeding motor is fixed to the fixed plate, and its movable end is connected to the movable plate, driving the movable plate to move towards or away from the conveyor table. The movable plate is also connected to a push plate, driving the push plate to move synchronously. The feeding motor drives the push plate to push the side negative plate onto the conveyor table.

[0009] Furthermore, a partition is provided between the feeding device and the stacking device, and a groove is provided at the bottom of the partition. The pusher plate pushes the side negative plate through the groove and into the conveyor table.

[0010] Furthermore, the stacking device also includes a baffle on the side of the conveyor chain and conveyor table away from the partition. The baffle provides a barrier to the side negative plate, preventing it from falling off the conveyor table, and the baffle and the partition form a barrier on both sides of the electrode assembly.

[0011] Furthermore, both the baffles and partitions extend beyond the discharge end of the conveyor chain. After the electrode assembly is pushed out from the discharge end of the conveyor chain, it stacks with the side negative plate to form an electrode group. The baffles and partitions define the electrode group from both sides to ensure that the electrode group is neat.

[0012] Furthermore, the stacking mechanism also includes a feeding device, which includes a guide plate with a guide groove, a connecting shaft that moves back and forth along the guide plate under the drive of the feeding power, and a take-up seat connected to the connecting seat via a rotating shaft and guided by the guide groove to rotate around the rotating shaft. A suction cup is provided on one side of the take-up seat. When the take-up seat retracts along the guide groove until the suction cup faces downwards, the suction surface of the suction cup is located above the support plate. When the take-up seat retracts and the suction cup is released, the side negative plate falls onto the support plate, allowing the push plate to push it into the conveyor table.

[0013] Furthermore, a guide rod is provided at one end of the tablet holder away from the rotation axis, with one end extending into the guide groove, and the suction surface of the suction cup is parallel to the length direction of the guide rod.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model provides a stacking device and a feeding device for the side negative plate at the rear of the discharge port of the disc-type stacking mechanism, and sets the stacking device as an upper and lower two-layer structure, so that the electrode plate group and the side negative plate can be fed to the stacking device at the same time, thereby completing the stacking and forming an electrode group.

[0016] 2. This utility model uses a feeding device to accurately place the side negative plate onto the support plate, and a pusher plate to push the side negative plate onto the conveyor table. The pusher rod then pushes the electrode group and the side negative plate forward to form an electrode group. With the limiting effect of the baffle and partition, the neatness of the electrode group is ensured, and the efficiency of electrode group stacking is improved. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only, representing schematic diagrams only, not actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Example 1

[0026] A lead-acid battery stacking mechanism, such as Figure 1As shown, the assembly includes a disc stacker 1, a feeding device 2, a wafer feeding device 3, a stacking device 4, a support platform 7, and a partition 6. The disc stacker 1 and the stacking device 4 are arranged in the same direction along the process flow, meaning their discharge directions are the same. However, the feeding directions of the feeding device 2 and the wafer feeding device 3 are perpendicular to the discharge direction of the stacking device 4. Therefore, overall, the larger disc stacker 1 is located at one end, while the support platform 7 is located at the other end, and so on. Figure 2 As shown, the feeding device 2, the wafer feeding device 3, and the stacking device 4 are all mounted on the support platform 7. The feeding device 2 and the wafer feeding device 3 are located on the same side of the stacking device 4, ensuring the compactness of the entire stacking mechanism and reducing the floor space. During operation, the positive electrode plate and the negative electrode plate are stacked into an electrode plate group 52 by the disc-type stacking machine 1. The feeding device 2 places the side negative plates 51 one by one onto the wafer feeding device 3. The wafer feeding device 3 then pushes the side negative plates 51 to the stacking device 4. The stacking device 4 then stacks the electrode plate group 52 and the side negative plates 51 into an electrode group 5.

[0027] like Figure 3 and Figure 4 As shown, the stacking device 4 includes a conveyor chain 41 for transporting the electrode assembly 52, a conveyor table 42 for transporting the negative electrode 51, a baffle 44 for limiting and guiding the electrode, and a push rod 43 for pushing the electrode forward. The conveyor chain 41 and the conveyor table 42 have a two-layer structure. In this embodiment, the conveyor chain 41 is located on the upper layer and the conveyor table 42 is located on the lower layer. Alternatively, the conveyor table 42 can be placed on the upper layer and the conveyor chain 41 on the lower layer. A gap is provided between the conveyor chain 41 and the conveyor table 42. The two ends of the electrode assembly 52 overlap the two ends of the gap in the conveyor chain 41, and the two ends of the negative electrode 51 overlap the two ends of the gap in the conveyor table 42. The push rod 43 moves along the gap between the conveyor chain 41 and the conveyor table 42 to push the electrode forward. Figure 4 As shown, in this embodiment, the conveyor chain 41 uses two rows of parallel rollers, with a gap between the two rows of rollers. Figure 1 As shown, the feeding end of the conveyor chain 41 extends to the discharge port of the disc stacker 1. The electrode plate group 52 coming out of the disc stacker 1 enters the conveyor chain 41 and moves forward along the conveyor chain 41 under the push of the push rod 43.

[0028] like Figures 1-5 As shown, the baffle 44 is arranged along the length of the conveyor chain 41 and the conveyor table 42, and is located on the side of the conveyor chain 41 and the conveyor table 42 away from the sheet feeding device 3, thus limiting and guiding the electrode plate assembly 52 and the side negative plate 51. Figure 4 and Figure 5As shown, the length of the baffle 44 exceeds the length of the conveyor chain 41. When the electrode group 52 moves out of the conveyor chain 41, the electrode group 52 and the side negative plate 51 are directly superimposed to form the electrode group 5. During this superposition process, the baffle 44 continues to limit and guide the electrode group 5 to prevent the electrode group 5 from scattering.

[0029] like Figures 3-5 As shown, the feeding device 3 includes a support plate 31 for placing the side negative plate 51, a push plate 32 for pushing the side negative plate 51 to the conveyor table 42, a feeding power 33 for pushing the push plate 32, a fixing plate 34 for fixing the feeding power 33, and a movable plate 36 for connecting the feeding power 33 and the push plate 32. In this embodiment, the fixing plate 34 is vertically arranged at one end of the support platform 7, the feeding power 33 (in this embodiment, a cylinder) is fixed to the fixing plate 34, the movable plate 36 is generally L-shaped, one end is connected to the movable end of the feeding power 33, and the other end is connected to the push plate 32. The side of the fixing plate 34 facing the support plate 31 is also provided with a feeding guide rail 35. The movable plate 36 moves along the feeding guide rail 35 under the drive of the feeding power 33, thereby driving the push plate 32 to move closer to or away from the conveyor table 42. The support plate 31 is arranged parallel above the support platform 7, and the support plate 31 has multiple through slots. Each through slot has a push plate 32 that passes through from bottom to top. When the side negative plate 51 is placed on the support plate 31, the push plate 32 pushes the side negative plate 51 to the conveyor table 42.

[0030] like Figure 3 As shown, the partition 6 is disposed between the sheet feeding device 3 and the sheet stacking device 4, and the bottom of the partition 6 is provided with a groove. In this embodiment, in order to simplify the structure, as shown... Figure 5 As shown, one end of the support plate 31 passes under the groove of the partition plate 6 and extends to the stacking device 4, forming part of the conveyor table 42. This allows the side negative plate 51 to be pushed from the feeding device 3 to the stacking device 4 along the support plate 31. Ideally, the height of the groove should be slightly greater than the thickness of the side negative plate 51 so that the side negative plate 51 can pass through easily. However, the height of the groove should not be too high. When the electrode assembly 52 passes over the conveyor chain 41 above the conveyor table 42, the partition plate 6, together with the baffle 44, can limit and guide the electrode assembly 52 on both sides. Moreover, the length of the partition plate 6 extends beyond the discharge port of the conveyor chain 41, and there should ideally be no gap between the partition plate 6 and the support platform 7 at this part so that the partition plate 6, together with the baffle 44, can limit and guide the electrode assembly 5.

[0031] like Figure 6 and Figure 7As shown, the feeding device 2 includes a guide plate 21 fixed to the support platform 7, a feeding power 27 (also a cylinder in this embodiment) fixed to the guide plate 21, a connecting seat 23 that moves back and forth driven by the feeding power 27, a take-up seat 25 that converts the reciprocating motion into rotational motion and is connected to the connecting seat 23 by a rotating shaft 24, and a suction cup 26 disposed on the suction side negative plate 51 of the take-up seat 25. The guide plate 21 is perpendicular to the support platform 7 and has a guide groove 211. The side of the guide plate 21 facing the connecting seat 23 is also provided with a feeding guide rail 28, and the connecting seat 23 slides along the feeding guide rail 28 driven by the feeding power 27. A guide rod 22 extending into the guide groove 211 is provided at the end of the pick-up seat 25 away from the rotating shaft 24. When the feeding power 27 drives the connecting seat 23 to reciprocate, the guide rod 22 moves along the guide groove 211, causing the pick-up seat 25 to rotate along the rotating shaft 24, thus changing the adsorption surface of the suction cup 26. When the connecting seat 23 retracts, the adsorption surface of the suction cup 26 is parallel to the support plate 31 and located above the through groove on the support plate 31, so as to transport the negative electrode plate 51 to the through groove. The push plate 32 then pushes the side negative plate 51 to the conveying table 42. In this embodiment, there are two suction cups 26, and an appropriate number of suction cups 26 can be selected according to the size of the side negative plate 51.

[0032] The above embodiments are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the protection scope of the present invention, which should be defined by the claims.
