Description

Technical Field

[0001] The present invention relates to the technical field of lead-acid battery manufacturing equipment, in particular to a battery casting welding machine. Background Art

[0002] The structure of a lead-acid battery primarily consists of components such as a positive plate group, a negative plate group, a separator, a casing, and an electrolyte. Within a single lead-acid battery, the plates are connected together via a busbar formed through a cast-welding process. Prior to the cast-welding process, the plate group and separator are manually formed into a semi-cased battery component. This semi-cased battery component's top and the tabs of each plate extend a certain distance from the opening of the battery casing, while a gap exists between the bottom of the plate group and the bottom surface of the casing's inner cavity. The general process for the cast-welding of a semi-cased battery component involves moving the semi-cased battery component to a cast-welding station, using molten lead for cast-welding. After sufficient cooling, the lead forms a busbar, and the remaining components are then assembled and the electrolyte is poured into the battery to produce the finished lead-acid battery.

In this embodiment, each battery clamping assembly can be flipped around an axis located in the horizontal direction at a first preset angle; the cast welding drive assembly includes a turntable drive unit 512 and a flip drive unit 513 provided on the frame 1, the turntable drive unit 512 is driven and connected to the turntable 511 to drive the turntable 511 to rotate, the flip drive unit 513 corresponds to the feed position 131 and is movably arranged in the up and down directions to have a driving position close to the turntable 511 and a disengagement position away from the turntable 511. When the flip drive unit 513 is in the driving position, it can be driven and connected to the battery clamping assembly located at the feed position 131 to drive the battery clamping assembly to flip.

[0072] In this solution, when the battery 200 to be assembled moves from the battery conveyor belt to the feeding position 131, the battery clamping assembly located at the feeding position 131 clamps the battery 200; at this time, the flipping drive unit 513 switches from the disengaged position to the driving position to be driven and connected with the battery clamping assembly located at the feeding position 131, and drives the battery clamping assembly to flip over a first preset angle, so that the battery 200 follows the battery clamping assembly to flip over the first preset angle, so as to facilitate subsequent cast welding; after the battery 200 is flipped into place, the turntable drive unit 512 drives the turntable 511 to rotate, so that the flipped battery clamping assembly rotates from the feeding position 131 to the welding position 132 for cast welding, and after the battery 200 is cast welded, the turntable drive unit 512 continues to drive the turntable 511 to rotate, so that the cast-welded battery 200 moves from the casting position to the unloading position 133, and this cycle is repeated to realize automatic flipping and cast welding of the battery 200, thereby greatly improving the cast welding efficiency. It should be noted that, in this embodiment, the first preset angle is 180°.

[0073] Specifically, see Figure 8 and Figure 9The battery clamping assembly includes a battery mounting frame 514, a battery clamping drive assembly and two clamping plates 515; the battery mounting frame 514 is rotatable around an axis in the horizontal direction and is arranged on the turntable 511, and has a accommodating space that is open at both ends in the upper and lower directions, and can be driven by the flip drive unit 513 to flip over a first preset angle; the two clamping plates 515 are oppositely arranged at the two ends of the accommodating space in the horizontal direction, and have a movable stroke of approaching and moving away from each other, so as to clamp the battery 200 when approaching each other, and each clamping plate 515 is provided with a threaded hole and a guide hole along its movable direction; the battery clamping drive assembly includes a screw rod 516 passed through each threaded hole, and a guide rod 517 passed through each guide hole, the screw rod 516 is horizontally spanned on the battery mounting frame 514, and the threads at its two ends have opposite rotation directions, so as to drive the two clamping plates 515 to approach and move away from each other during rotation, and the guide rod 517 is horizontally spanned on the battery mounting frame 514.

[0074] In this embodiment, the two clamping plates 515 are simultaneously driven toward and away from each other by the rotation of the screw rod 516 to achieve the clamping and loosening of the battery 200, which has a simple structure and saves costs. Specifically, in this embodiment, each clamping plate 515 is provided with a threaded hole and a guide hole at both ends in the length direction; correspondingly, two groups of screw rods 516 and guide rods 517 are provided, and the two groups of screw rods 516 are driven by a belt to improve transmission stability. In addition, it should be noted that in order to facilitate the two clamping plates 515 to clamp the batteries 200 from the battery conveyor belt, a lifting platform is provided at the casting and welding station 13. The lifting platform moves in the up and down direction and is located below the battery clamping assembly to receive the batteries 200 from the battery conveyor belt and move upward to be clamped by the two clamping plates 515.

[0075] Specifically, see Figure 10The battery casting and welding mold 52 includes a mold body 521, a third driving part 523 and a plurality of movable plates 522; the mold body 521 is arranged on the frame 1 and is located at the welding position 132, and its upper end surface is recessed with two side grooves 521a along the horizontal interval, and at least one middle groove 521b is recessed between the two side grooves 521a, and a side partition 5211 is horizontally arranged in each side groove 521a to form two side forming cavities along the longitudinal interval, and a middle partition 5212 is horizontally arranged in each middle groove 521b to form two middle forming cavities along the longitudinal interval, and each middle forming cavity is aligned with the corresponding A guide channel is provided longitudinally on the side opposite to the middle partition 5212; a plurality of movable plates 522 correspond to a plurality of middle molding cavities, and each movable plate 522 is movably provided in the corresponding guide channel along the longitudinal direction, so that when it approaches the corresponding middle partition 5212, the middle molding cavity can be divided into two sub-molding cavities along the transverse direction, and a connecting channel connecting the two sub-molding cavities is formed between the movable plate 522 and the bottom wall of the corresponding middle molding cavity; a third driving part 523 is provided on the mold body 521, and is driven and connected to each movable plate 522, so as to drive the movable plate 522 to move.

[0076] In this embodiment, the third drive unit 523 drives each movable plate 522 to move close to the corresponding middle partition 5212, thereby separating each middle forming cavity into two sub-forming cavities along the horizontal direction. Then, a casting welding liquid is injected into each side forming cavity and the middle forming cavity. Since the adjacent sub-forming cavities are connected by a connecting channel, when the tabs inserted into the sub-forming cavity are cast-welded to form a busbar, the corresponding adjacent busbars can also be connected by the casting welding liquid located in the connecting channel. After the casting welding liquid solidifies, the third drive unit 523 drives the movable plate 522 to move away from the corresponding middle partition 5212 to facilitate the removal of the electrode group 210. A clearance gap is formed at the movable plate 522 corresponding to the cast-welded electrode group 210 to facilitate the installation of the cast-welded electrode group 210 in the battery box. In this way, a single casting welding operation can form a busbar while also completing the connection between adjacent busbars, improving casting welding efficiency and facilitating operation. In this embodiment, the horizontal, vertical and vertical directions are shown as F4, F5 and F6 respectively in the accompanying drawings. In addition, in this embodiment, each driving part can be configured as a cylinder or a motor, as long as the corresponding function is achieved, and there is no limitation here.

[0077] Specifically, the mold body 521 is provided with a flow channel extending laterally for conveying the casting welding liquid. A flow channel 521c is recessed between the side groove 521a and the adjacent middle groove 521b, and between two adjacent middle grooves 521b. The flow channel 521c is connected to the flow channel, and each of its lateral side walls has a diversion port. In this embodiment, the casting welding liquid in the flow channel first flows into each flow channel 521c, and then flows through the diversion port to each side molding cavity and each middle molding cavity, thereby reducing the oscillation of the casting welding liquid in each side molding cavity and each middle molding cavity. Specifically, the diversion port is provided at the upper end of the side wall of the flow channel 521c. In addition, to prevent the casting welding liquid in the flow channel 521c from being contaminated or splashed, in this embodiment, the battery casting welding mold 52 also includes a cover plate covering the opening of the flow channel 521c.

[0078] In addition, the bottom wall of the middle forming cavity is recessed with a middle forming hole on the movable stroke of the corresponding movable plate 522; when the movable plate 522 moves to be close to the corresponding middle partition plate 5212, it is spaced apart from the bottom wall of the middle forming hole in the upper and lower directions to form a connecting channel.

[0079] Further, see Figure 11 and Figure 12 The pole group feeding mechanism 2 includes a mounting seat 21, a material taking structure and a material taking driving structure: the mounting seat 21 is provided on the frame 1 and is located at the feeding station 11, and is movably arranged in the horizontal direction to have a movable stroke close to and away from the pole group clamping position 122; the material taking structure includes a fixed seat 22 movably arranged on the mounting seat 21 in the up and down directions, and two pole group clamping arms 23 arranged at intervals on the fixed seat 22 in the horizontal direction, the two pole group clamping arms 23 respectively have a clamping section 231, and a clamping gap 23a for clamping the pole group 210 is formed between the two clamping sections 231, and each pole group clamping arm 23 is movably arranged so that the corresponding clamping section 231 has A clamping position close to the other clamping section 231, and a loosening position away from the other clamping section 231, wherein an elastic reset member 26 is provided between the two pole group clamping arms 23, so that the clamping section 231 can be reset from the loosening position to the clamping position; the material picking drive structure includes a material picking drive part 24 provided on the fixed seat 22, and a transmission part 25 connected to the movable end 241 of the material picking drive part 24, the movable end 241 is located between the two pole group clamping arms 23, and is movably arranged in the up and down directions, the transmission part 25 is transmission-connected to each pole group clamping arm 23, so that when the movable end 241 moves, it can drive the clamping section 231 to switch from the clamping position to the loosening position.

[0080] In this embodiment, the material-taking drive unit 24 can be started to work so that the movable end 241 can move in the direction of approaching or moving away from the fixed seat 22, thereby driving the transmission unit 25 to move in the direction of approaching or moving away from the fixed seat 22. When the transmission unit 25 moves, it can drive the clamping section 231 to switch from the clamping position to the loose position, that is, the two clamping sections 231 are opened to facilitate the pole group 210 to enter the clamping gap 23a formed by the two clamping sections 231; after the pole group 210 enters the clamping gap 23a, the movable end 241 drives the conveying unit to move in the opposite direction, and the clamping section 231 is driven by the elastic reset member 26 to reset from the loose position to the clamping position, that is, the two clamping sections 231 approach each other to clamp the pole group 210 and enable transportation. This solution can simultaneously drive the two clamping sections 231 to move closer to or further away from each other through the transmission part 25 to clamp the pole group 210. The structure is simple, reliable and easy to implement. The transmission part 25 converts its movement in the direction of approaching and moving away from the fixed seat 22 into the mutual approach and distance of the two clamping sections 231, making the overall structure more compact.

[0081] In this embodiment, the transmission portion 25 is a roller mounted on the movable end 241. The pole group clamping arms 23 are rotatably connected to the fixed base 22. The side corresponding to the roller is a guide side 23b. The guide side 23b is inclined from the end closest to the fixed base 22 to the end away from the fixed base 22 toward the roller. In addition, the material retrieving structure and the material retrieving drive structure are provided in multiple corresponding ways.

The whole material structure includes a plurality of adjustment parts 28, and the plurality of adjustment parts 28 are jointly arranged to form an adjustment channel 28a for the pole group clamping part 271 to pass through. When the clamping part moves to the adjustment channel 28a, at least one adjustment part 28 can move close to or away from the pole group clamping part 271, and when it moves to a position close to the pole group clamping part 271, it is used to press the pole group 210 so that the multiple pole plates of the pole group 210 are aligned.

[0083] In this solution, since the clamping portion can rotate to a second preset angle when moving toward the material extraction position 112, the clamping portion can be used to rotate multiple electrode plates that are naturally laid flat to the side with the tabs pointing away from the frame 1, so as to facilitate the next step of material extraction. At the same time, when the clamping portion delivers the multiple electrode plates to the adjustment channel 28a, the adjustment portion 28 can move to a position close to the clamping portion to press against the side walls of the multiple electrode plates, so that the multiple electrode plates can be aligned, that is, the tabs of the multiple electrode plates are aligned, so as to improve the quality of the tab casting and welding, thereby ensuring the quality of the battery 200. In this embodiment, the second preset angle is 90°. In addition, a feed conveyor chain is provided on the side of the material transfer position 111 away from the material extraction position 112 to convey the flatly laid electrode group 210 to the material transfer position 111.
