Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery manufacturing technology, and in particular relates to a battery busbar sorting and output device. Background Technology

[0002] Most lead-acid batteries are 12V batteries, consisting of 6 cells. Each cell has positive and negative plates. The positive and negative plates need to be connected in parallel to weld the tabs together. The current collectors after welding are collectively called busbars. To ensure the service life and high-rate discharge characteristics of lead-acid batteries, the busbars are generally welded by hot melting of lead-tin alloy. The high-temperature furnace melts the lead, and then the liquid lead is poured into a mold. The tabs in the mold are heated to fuse and weld. In this process, the high-temperature furnace needs to work continuously for 24 hours, which consumes a lot of energy, and the production process is highly polluting, has high material loss, and the welding quality between the tabs and the busbar is not high.

[0003] Therefore, an increasing number of companies are choosing to use non-lead metal strips as the busbars for batteries. For example, patent documents CN106549183A and CN205752350U both propose using copper or other non-lead metal materials as busbars, connected to the tabs using a mechanical fixing method. Patent document CN120033347A discloses a rapid welding battery busbar structure and manufacturing process, proposing the use of non-lead metal strips made of metals or alloys with higher conductivity than lead, as well as non-lead metal positive and negative terminals. The non-lead metal strips are rapidly heated by electricity and welded to the cluster tabs and non-lead metal positive and negative terminals. After the welding is firm, the busbar is formed by cutting and sealed with glue. The above solutions improve the specific energy of lead-acid batteries, reduce the material cost of lead-acid batteries, improve production efficiency, reduce energy consumption, and reduce pollution.

[0004] However, the aforementioned patent documents do not disclose the specific structure of the automated processing equipment. Furthermore, due to the use of prefabricated metal strips as busbars, the overall processing method differs significantly from the traditional method of using lead-molded busbars. Traditional equipment cannot be directly used in the process of welding prefabricated metal strips to battery tabs. Moreover, the use of prefabricated metal strips as busbars makes it possible to fully automate the feeding of busbars. Therefore, the first challenge is to overcome the problem of how to neatly arrange and output the messy and disordered busbars. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a battery busbar sorting and output device, which can realize the sequential and orderly output of a single busbar.

[0006] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0007] A battery busbar sorting and output device includes a housing and a dial assembly. The upper part of the housing forms a hopper for placing the busbars. The bottom of the hopper is inclined. The housing is provided with a support plate and a front baffle. The front end of the support plate and the lower end of the front baffle gradually approach each other to form a discharge port that can only accommodate a single busbar. The dial assembly is located at the discharge port of the hopper. By rotating the dial assembly, the stacked busbars are made to pass through the discharge port in sequence.

[0008] The hopper in the above structure has an inclined bottom: it automatically feeds materials by gravity, reducing power consumption and avoiding busbar stacking jams; and it uses a dial assembly to separate the stacked busbars into a single-layer flat state, solving the problem of multiple busbars sticking together; the narrow gap formed by the tray and the front baffle strictly limits the passage of a single busbar, preventing multiple pieces from being discharged at the same time; the above structure realizes the transformation of disordered busbar stacking into ordered single-layer separation and output, laying the foundation for the fully automated process of subsequent battery busbar welding.

[0009] As a preferred embodiment, the lower part of the pallet at the feed port is also equipped with a roller brush. The roller brush blocks and supports the downward-moving manifold and adjusts the manifold to a horizontal state. The roller brush structure forms a flexible resistance to the downward-moving strip material, avoiding impact and accumulation caused by gravity acceleration, and improving the stability of the feed. At the same time, the rotational friction of the roller brush forces the skewed manifold to return to a horizontal position, adapting to differences in the posture of the incoming material.

[0010] As a preferred embodiment, the dial assembly includes a drive motor, a rotating shaft, and a dial wheel. The rotating shaft passes through the housing and is rotatably connected to the housing. The drive motor is fixed to the housing and drives the rotating shaft to rotate. The dial wheel is fixed to the rotating shaft, and a gap is formed between the dial wheel and the support plate to accommodate a single busbar.

[0011] As a preferred embodiment, a feeding channel is also included. The discharge port at the bottom of the hopper connects to the feeding channel, and a baffle is provided at the outlet of the feeding channel to prevent the manifold from falling off. The baffle at the outlet of the feeding channel prevents the manifold from slipping out, ensuring stable directional conveying.

[0012] As a preferred embodiment, the feeding channel includes upper and lower sets of slats, with a gap between the upper and lower sets of slats to accommodate a single busbar laid flat and passing through. The narrow gap formed by the upper and lower slats strictly limits the passage of a single busbar, avoiding multiple rows from overlapping;

[0013] As a preferred embodiment, the lower strip in the feeding channel is a support strip, which is inclined and bent horizontally at the front end, with two support strips arranged parallel and spaced apart. In the above structure, the inclined section of the support strip slides down under gravity, while the horizontal section provides stable support, reducing the risk of jamming.

[0014] As a preferred embodiment, the upper slat has the same shape as the support strip and is fixed to the housing by a limiting component.

[0015] As a preferred embodiment, the limiting assembly includes a crossbeam, a fixing post, and a connecting block. Both ends of the crossbeam are fixed to two side plates, one end of the fixing post is connected to the crossbeam, and the other end of the fixing post is fixed to an upper slat via the connecting block. The upper slat and the support strip form a gap allowing only a single manifold to pass through. The rigid limiting assembly resists vibration deformation, ensuring a consistently precise channel gap over the long term.

[0016] As a preferred embodiment, the fixing column passes through the crossbeam, and a limiting component is provided at the end of the fixing column that passes through the crossbeam. A spring is also fitted on the fixing column, with one end of the spring abutting against the crossbeam and the other end abutting against the connecting block.

[0017] As a preferred embodiment, there are two limiting components, namely limiting component A and limiting component B, and the upper strip is divided into two sections, namely a straight strip and an arc strip, which are fixed to the housing by limiting component A and limiting component B respectively.

[0018] As a preferred embodiment, the lower end of the front baffle is bent forward to form an arc surface, and the lower end of the front baffle overlaps with one end of the straight pressure strip, the other end of the straight pressure strip overlaps with one end of the arc pressure strip, and a gap is left between the end face of the other end of the arc pressure strip and the outer end face of the support strip.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The hopper of this invention features an inclined bottom: it utilizes gravity for automatic feeding, reducing power consumption and preventing busbar stacking jams; and it uses a dial assembly to separate stacked busbars into a single-layer flat state, solving the problem of multiple busbars sticking together; the narrow gap formed by the tray and the front baffle strictly limits the passage of a single busbar, preventing multiple pieces from being discharged simultaneously; the equipment of this invention realizes the transformation from disordered stacking of busbars to ordered single-layer separation and output, laying the foundation for the fully automated process of subsequent battery busbar welding.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0033] like Figures 1 to 6 As shown, a battery busbar sorting and output device includes a housing, a feeding channel 100, and a dial assembly. The upper part of the housing forms a hopper, the bottom of which is inclined, and the outlet at the bottom of the hopper 100 is connected to the feeding channel. The dial assembly is disposed on the housing at the junction of the hopper and the feeding channel. By rotating the dial assembly, the stacked busbars 5 are arranged in a flat manner and enter the feeding channel in sequence, and the busbars 5 move along the width direction of the busbars 5. The feeding channel is disposed inside the housing and includes upper and lower sets of slats. A gap is formed between the upper and lower sets of slats to accommodate a single busbar 5 lying flat through. The length of the lower slat is greater than the length of the upper slat. A baffle is also provided at the outlet of the feeding channel to prevent the busbars 5 from falling.

[0034] The housing includes two side plates 11 and a support plate 10 and a front baffle 13 clamped and fixed between the two side plates. The two side plates 11, the support plate 10 and the front baffle 13 form a material hopper. One end of the support plate 10 and the lower end of the front baffle 13 approach each other to form a discharge port. A manifold 5 is placed inside the material hopper. The distance between the two side plates 11 is equal to or slightly greater than the length of the manifold 5. In this embodiment, the manifold 5 is a non-lead metal strip.

[0035] The support plate 10 is inclined, with the front lower than the back. A roller brush 118 is also provided at the lower part of the support plate 10. A through hole is opened on the support plate 10, and at least part of the roller brush 118 protrudes through the through hole, so that the roller brush 118 supports and adjusts the manifold 5 horizontally. The manifold 5 slides downward under the action of gravity. When the horizontal manifold 5 reaches the roller brush 118, it drives the roller brush 118 to rotate and then continues to slide down. When the inclined manifold 5 reaches the roller brush 118, the roller brush 118 increases the sliding resistance of the end of the manifold 5 that first contacts the roller brush 118, so that the sliding speed of that end slows down, while the other end of the manifold maintains the original sliding speed. Finally, the manifold becomes horizontal and continues to slide down.

[0036] The lower strip in the feeding channel is a support strip 116. Two support strips 116 are arranged in parallel and spaced apart. One end of each support strip 116 is fixed to both sides of the through hole, and the end of the support strip 116 is connected to the support plate with a sloping surface. The lower part of the front baffle 13 is folded backward to form a V-shaped feeding port with the support plate 10. The lower end of the front baffle 13 is bent forward to form an arc surface, and the end of the front baffle 13 forms a gap with the support strip 116. The gap is equal to or slightly larger than the thickness of the manifold 5. The manifold 5 in the hopper enters the gap sequentially under the action of gravity.

[0037] The front end of the support bar 116 is horizontal. A cylinder fixing plate 117 is fixed between the two support bars. A separation cylinder 114 is fixed to the bottom of the cylinder fixing plate. A movable support block 115 is fixed to the piston rod of the separation cylinder 114. An end support block 120 is also fixed between the two support bars. The end support block 120 is located at the front end of the cylinder fixing plate 117. The width of the end support block 120 is at least the width of two manifolds 5. The separation cylinder 114 drives the movable support block 115 to move together with or separate from the end support block 120. The width of the movable support block 115 is the same as the width of one manifold, and the retaining edge is provided on the outer side of the movable support block 115.

[0038] The front baffle 12 is also provided with a rotating shaft 14. A drive motor 12 is fixed on one of the side plates 11. One end of the rotating shaft 14 is connected to the drive motor 12 and is driven by the drive motor 12 to rotate. The other end of the rotating shaft 14 is mounted on another side plate 11 through a mounting plate 119. Two dial wheels 15 are fixed at intervals on the rotating shaft 14. The front baffle 12 is also provided with an elongated through hole 122. The two dial wheels 15 pass through the corresponding elongated through hole 122. After the dial wheels 15 rotate, they can push the stacked busbars 5 away from the gap opening, thereby ensuring that the single busbars 5 enter the gap opening in a parallel manner.

[0039] Two sets of limiting mechanisms are fixed in front of the rotating shaft 14, namely limiting mechanism A and limiting mechanism B. Limiting mechanism A includes a crossbeam 16, a fixing column 17, a connecting block 18, and a straight pressure strip 111. The two ends of the crossbeam 16 are fixed to the two side plates respectively. One end of the fixing column 17 is connected to the crossbeam 16, and the other end of the fixing column 17 is fixed to the straight pressure strip 11 through the connecting block 18. The straight pressure strip 111 and the support strip 116 form a gap that allows only a single busbar to pass through. The front end of the support strip 116 transitions from a rounded corner to a horizontal shape. The limiting mechanism B is located above the front end of the support strip 116. The structure of the limiting mechanism B is largely the same as that of the limiting mechanism A. In order to match the shape of the support strip 116, the straight pressure strip 111 is replaced with an arc-shaped pressure strip 110. The arc-shaped pressure strip 110 and the support strip 116 also form a gap that allows only a single busbar to pass through. The material feeding channel is formed by using straight or curved pressure strips in conjunction with support strips. This results in a smaller contact area between the material feeding channel and the manifold, which reduces the friction between the material feeding channel and the manifold while ensuring stable support, thus ensuring smooth material feeding from the manifold.

[0040] A spring 19 is also fitted on the fixed column 17. The spring 19 allows the straight pressure bar 111 or the arc-shaped pressure bar 110 to float slightly with the busbar, so as to avoid the straight pressure bar 111 from contacting the busbar too tightly, thereby affecting the movement of the busbar.

[0041] The lower end of the front baffle 13 overlaps with one end of the straight pressure strip 111, and the other end of the straight pressure strip 111 overlaps with one end of the arc-shaped pressure strip 110. The other end of the arc-shaped pressure strip 110 extends to the upper part of the end support block 120, and there is a gap between the outer end face of the arc-shaped pressure strip 110 and the outer end face of the end support block 120. This gap is the width of a busbar, which facilitates the transfer of the end busbar.

[0042] The crossbeam 16 of the limiting mechanism B is also equipped with a clamping cylinder 112. The piston rod of the clamping cylinder 112 is fixed with a clamping column at the end. When the clamping cylinder 112 is working, the clamping column clamps the second manifold 5 arranged from the outside to the inside on the end support block 120, and makes the outermost manifold 5 on the end support block 120 free.

[0043] The busbars slide downwards under gravity, and under the action of the roller brush and the dial wheel, the numerous busbars in the hopper are arranged in a single layer of horizontal parallel arrangement. They then enter the gap between the end of the front baffle 13 and the support bar 116, the gap between the straight pressure bar 111 and the support bar 116, and the gap between the arc-shaped pressure bar 110 and the support bar 116, and finally reach the moving support block 115 and are blocked by the retaining edge. At this time, the pressing column of the pressing cylinder presses the second busbar 5 arranged from the outside to the inside on the end support block 120, and the separating cylinder pushes out the moving support block, so that the busbars on the moving support block are arranged at a certain distance from the outermost busbar on the end support block. This distance is the same as the distance between two adjacent rows of tabs on the battery. Then the translation module 2 transfers the two arranged busbars to the next station.

[0044] The limiting mechanism A is also equipped with a material detection sensor A113 on the crossbeam, a material detection sensor B121 on the side plate of the dial wheel, and a material detection sensor C on the movable support block 115.
