During the production process of lead-acid batteries, in order to shorten the current path and improve the discharge performance of the lead-acid battery, it is usually necessary to cast and weld the pole tabs of the plates to form a busbar and poles.

[0038] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1:

[0041] Please see the attached Figure 1 The multi-station external cold casting welding machine of the present invention includes a turnover frame 1, which is provided with a plurality of turnover areas 11. Specifically, there can be two turnover areas 11. It can be understood that this is not a specific limitation on the number of turnover areas 11, and those skilled in the art can replace them on this basis. A fixture 2 is provided in the turnover area 11 of the turnover frame 1. A conveying mechanism 3 for conveying workpieces to each turnover area 11 is provided on one side of the turnover frame 1. A cast welding mechanism 4 is provided on one side of the turnover frame 1, which can be used for multi-station cast welding of lead-acid batteries 9.

[0042] Among them, several turnover areas 11 are distributed side by side on the turnover rack 1, and the batteries 9 are loaded and unloaded in the turnover areas 11 for turnover. The fixture 2 is set in the turnover area 11. Specifically, the fixture 2 is a long plate with a through hole opened through it. The through hole is a rectangular through hole adapted to the outer shell of the battery 9. As shown in some specific embodiments, the battery 9 can be placed in the through hole and positioned by being engaged with the fixture 2. In other specific embodiments, the fixture 2 can be provided with a support bar in the through hole, and the battery 9 can be placed at the through hole via the support bar.

[0043] As shown in some specific embodiments, the conveying mechanism 3 is arranged above the turnover frame 1, and the conveying mechanism 3 includes a conveying clamp 31 for clamping or releasing the workpiece. The conveying clamp 31 is transmission-connected to a conveying drive 32. Specifically, the conveying drive 32 preferably but not limited to a conveying linear module. The slide of the conveying linear module is transmission-connected to the conveying clamp 31 to drive the conveying clamp 31 to move in a horizontal direction and then reciprocate in each turnover area 11. In other specific embodiments, the conveying drive 32 can adopt a conveying rack 3152, a conveying gear 3151 and a conveying motor to drive the conveying clamp 31 for transmission.

[0044] In a preferred embodiment, a movable seat 34 is provided on one side of the conveying clamp 31, and the movable seat 34 is transmission-connected to the conveying drive member 32. A lifting drive member 35 is provided between the movable seat 34 and the conveying clamp 31. Specifically, the lifting drive member 35 preferably but not limited to adopts a lifting linear module, and the slide of the lifting linear module is transmission-connected to the conveying clamp 31. The lifting drive member 35 can drive the conveying clamp 31 to rise and fall to place or clamp the battery 9.

[0045] The cast welding mechanism 4 is arranged corresponding to the turnover area 11. The cast welding mechanism 4 can perform multi-station cast welding of batteries 9. The conveying mechanism 3 conveys the batteries 9 to the jig 2. The cast welding mechanism 4 performs cast welding of the batteries 9 to cast weld the tabs of each plate in the battery 9 to form a busbar.

[0046] When the battery 9 to be cast-welded is loaded, the conveyor clamp 31 clamps the battery 9 to be cast-welded, and the conveyor drive 32 drives the movable seat 34 to move horizontally. The movable seat 34 drives the conveyor clamp 31 to the corresponding turnover area 11. The lifting drive 35 drives the conveyor clamp 31 to descend. The conveyor clamp 31 places the clamped battery 9 to be welded on the fixture 2, and the cast welding mechanism 4 casts the battery 9 on the fixture 2. The conveyor clamp 31 can clamp the already cast-welded battery 9, and then the conveyor drive 32 drives the conveyor clamp 31 to convey the already cast-welded battery 9 and unload it. The conveyor mechanism 3 rotates the battery 9, which is conducive to improving the convenience of loading and unloading the battery 9 and can meet the multi-station cast welding requirements of the cast welding machine. Compared with the traditional turnover rack 1, the turnover rack 1 is provided with multiple turnover areas 11 and cooperates with the conveyor mechanism 3 to convey the battery 9, which is conducive to improving the production efficiency of the cast welding machine.

[0047] Example 2:

[0048] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the transmission mechanism 3 and the turnover frame 1 of the utility model. Figure 1-3 .

[0049] See Figure 1 and Figure 2 The conveying clamp 31 of this embodiment includes a frame 33, and one side of the frame 33 is provided with a clamping member 313 for clamping the battery 9. The first clamping plate 311 and the second clamping plate 312 are both transmission-connected with a clamping drive member 313. Specifically, the clamping drive member 313 is provided on the frame 33. The clamping drive member 313 is preferably but not limited to a clamping cylinder. The output end of the clamping cylinder is transmission-connected with the first clamping plate 311 or the second clamping plate 312. When the stroke of the clamping cylinder changes, the first clamping plate 311 and the second clamping plate 312 move closer to or farther away from each other to clamp or release the battery 9.

[0050] In a preferred embodiment, a connecting rod 314 is provided on the first clamping plate 311. The end of the connecting rod 314 away from the first clamping plate 311 passes through the second clamping plate 312. The second clamping plate 312 is slidably connected to the connecting rod 314. When the clamping driver 313 drives the first clamping plate 311 and the second clamping plate 312 toward or away from each other, the second clamping plate 312 slides on the connecting rod 314, thereby improving the clamping stability of the transfer clamp 31. The first clamping plate 311 is provided with a flipping driver 3153 for driving the first clamping plate 311 to rotate. When the flipping driver 3153 drives the first clamping plate 311 to rotate, the first clamping plate 311 drives the second clamping plate 312 to rotate via the connecting rod 314, thereby flipping the battery 9 clamped by the first clamping plate 311 and the second clamping plate 312. This can flip the battery 9 with the tab facing upward to a position with the tab facing downward, facilitating subsequent cast welding operations and improving user flexibility.

[0051] In a preferred embodiment, an adapter seat 331 is slidably provided on the frame body 33. Specifically, the adapter seat 331 is located on the side of the first clamping plate 311 away from the second clamping plate 312. A guide rod and a sleeve are provided between the adapter seat 331 and the frame body 33, wherein the sleeve is provided on the frame body 33, the guide rod is passed through the sleeve and is connected to the adapter seat 331, and the guide rod and the sleeve cooperate to play a certain guiding role in the movement of the adapter seat 331.

[0052] The adapter seat 331 is provided with a flip shaft 332, which is rotatably connected to the adapter seat 331. Specifically, the flip shaft 332 can be rotatably connected to the adapter seat 331 through a bearing. The flip shaft 332 is horizontally arranged, and one end of the flip shaft 332 along the axial direction is connected to the first clamping plate 311, and the other end is rotatably connected to the output end of the clamping drive member 313 on the corresponding side, so that the clamping drive member 313 can drive the flip shaft 332 to move in the horizontal direction to drive the first clamping plate 311 to move, while the flip shaft 332 can rotate relative to the output end of the clamping drive member 313 and drive the first clamping plate 311 to rotate.

[0053] In a preferred embodiment, the flip drive 3153 includes a gear 3151, which is sleeved on the flip shaft 332. The gear 3151 is meshed with a rack 3152, which is in transmission connection with the flip drive 3153. Specifically, the flip drive 3153 is preferably, but not limited to, a flip cylinder, the output end of which is in transmission connection with the rack 3152 to drive the rack 3152 to move horizontally. When the flip drive 3153 drives the rack 3152 to move linearly in the horizontal direction, the rack 3152 meshes with the gear 3151 to drive the gear 3151 to rotate, thereby driving the flip shaft 332 and the first clamping plate 311 to rotate. The first clamping plate 311 drives the second clamping plate 312 to rotate via the connecting rod 314. The first clamping plate 311 and the second clamping plate 312 flip the battery 9 clamped therein, and the battery 9 can automatically flip to a position where the tab faces downward, which is conducive to the battery 9 being in a state ready for cast welding.

[0054] When the conveying mechanism 3 conveys the battery 9, the clamping driver 313 drives the first clamping plate 311 and the second clamping plate 312 toward each other to clamp the battery 9. The flip driver 3153 drives the rack 3152 to move horizontally. The rack 3152 drives the gear 3151 to rotate. The gear 3151 drives the flip shaft 332 to rotate. The flip shaft 332 drives the first clamping plate 311 to rotate. The first clamping plate 311 drives the second clamping plate 312 to rotate synchronously via the connecting rod 314 to flip the battery 9 clamped by the first clamping plate 311 and the second clamping plate 312. The conveying driver 32 drives the conveying clamp 31 to move horizontally to convey the conveying clamp 31 to the corresponding turnover area 11. The lifting driver 35 drives the conveying clamp 31 to descend. The clamping driver 313 drives the first clamping plate 311 and the second clamping plate 312 to release the clamped battery 9, and the battery 9 is placed on the corresponding jig 2.

[0055] After the battery 9 is cast-welded, the conveying clamp 31 clamps the battery 9 , and the conveying driving member 32 drives the conveying clamp 31 , so that the conveying mechanism 3 can unload the cast-welded battery 9 .

[0056] See Figure 1 and Figure 3 In a preferred embodiment, the turnover rack 1 is provided with a turntable 12 in the turnover area 11, and the jig 2 is placed on the turntable 12. A positioning opening 122 is opened on the turntable 12, and a limiting member 13 for positioning the jig 2 is provided at the positioning opening 122 of the turntable 12. Specifically, the limiting member 13 can be a limiting frame, and the jig 2 is arranged in the limiting frame and can be inserted or pulled out of the limiting frame. The limiting frame makes it difficult for the jig 2 to move at will. When the limiting member 13 positions the jig 2, the pole ear of the battery 9 passes through the positioning opening 122.

[0057] The turntable 12 is in driving connection with a rotary drive member 121. Specifically, the rotary drive member 121 is preferably, but not limited to, a rotary motor. The output end of the rotary motor is in driving connection with the turntable 12 to drive the turntable 12 to rotate. In some specific embodiments shown, the turntable 12 is provided with a plurality of limit members 13. The turntable 12 can simultaneously rotate multiple groups of batteries 9, achieving continuous feeding of the batteries 9 for cast welding.

[0058] Furthermore, the turnover rack 1 is provided with a flux assembly 5 for dipping the battery 9 into flux. Specifically, the flux assembly 5 is disposed on the side of the turntable 12 away from the cast welding mechanism 4, and is located at the bottom of the turntable 12. When the turntable 12 drives the battery 9 to rotate to the flux assembly 5, the battery 9 placed on the fixture 2 can be dipped into the flux assembly 5 through the positioning opening 122. As shown in some specific embodiments, the flux assembly 5 includes a flux plate. Specifically, the flux plate can be provided with a sponge for absorbing flux. In other specific embodiments, the flux can be directly added to the flux plate. The flux plate is connected to a flux driver 52. The flux driver 52 is preferably, but not limited to, a flux cylinder. The output end of the flux cylinder is connected to the flux plate. When the flux driver 52 drives the flux plate upward, the battery 9 dips into the flux on the flux plate through the positioning opening 122. The flux driver 52 drives the flux plate downward, and the flux is added to the battery 9.

[0059] The conveying mechanism 3 conveys the battery 9 to the jig 2. At this time, the jig 2 is located on one side of the cast welding mechanism 4. The turnover drive 121 drives the turntable 12 to rotate to drive the batteries 9 to be cast-welded to rotate to the flux assembly 5, and the batteries 9 to be cast-welded are dipped in flux. At the same time, the conveying mechanism 3 can load the next group of batteries 9 to be cast-welded onto the empty jig 2 on the turntable 12. The turntable 12 rotates again, and the batteries 9 to be cast-welded that have been dipped in flux rotate with the jig 2 to return to the side of the cast welding mechanism 4. The cast welding mechanism 4 casts the batteries 9 to be cast-welded, and the next group of batteries 9 to be cast-welded rotates to the flux assembly 5 to dip in flux. The batteries 9 that have been cast-welded can continue to be unloaded by the conveying mechanism 3. The next battery 9 to be cast-welded, which has been dipped in flux, also rotates with the turntable 12 to one side of the cast-welding mechanism 4. The cast-welding mechanism 4 performs cast-welding on the next group of batteries 9. The turntable 12 cooperates with the conveying mechanism 3 to ensure that the turnover of multiple groups of batteries 9 is carried out in an orderly manner, further improving the production efficiency of the cast-welding machine.

[0060] Example 3:

[0061] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the cast welding mechanism 4 of the utility model, see Figures 4 to 9 .

In a preferred embodiment, the cast welding mechanism 4 includes a cast welding tank 41, and a cast welding bottom mold 42 is provided in the cast welding tank 41. Specifically, the cast welding bottom mold 42 is provided with a mold cavity for filling molten lead liquid. When the battery 9 enters the cast welding tank 41, the tabs of the battery 9 extend into the mold cavity of the cast welding bottom mold 42 for cast welding. Specifically, a cooling mechanism can be provided in the cast welding tank 41 for rapid cooling. The manner in which the cooling mechanism cools the battery 9 and the cast welding bottom mold 42 is known to those skilled in the art and is achievable, and is not described in detail in this embodiment.

[0063] A cast welding drive assembly 43 is provided on the frame 7 . The cast welding drive assembly 43 is located above the cast welding bottom mold 42 to drive the jig 2 and the battery 9 to enter or leave the cast welding tank 41 .

[0064] See Figure 4 and Figure 6 In a preferred embodiment, the cast welding drive assembly 43 includes a cast welding frame 431. During cast welding, the jig 2 is placed on the cast welding frame 431. The cast welding frame 431 supports the jig 2 and the battery 9 placed on the jig 2, moving it toward or away from the cast welding bottom mold 42 in the cast welding tank 41. A first cast welding cylinder 432 is provided between the cast welding frame 431 and the frame 7. The output end of the first cast welding cylinder 432 drives the cast welding frame 431 to move up and down, and the cast welding frame 431 drives the battery 9 toward or away from the cast welding bottom mold 42 to achieve cast welding. It is understood that in other specific embodiments, the first cast welding cylinder 432 can also use a first cast welding linear motor to drive the cast welding frame 431 to move up and down.

[0065] The cast welding frame 431 is provided with a cast welding pressure plate 434 for pressing the battery 9 against the cast welding bottom mold 42. The cast welding pressure plate 434 is slidably set on the cast welding frame 431. The cast welding pressure plate 434 is transmission-connected to the second cast welding cylinder 433. The output end of the second cast welding cylinder 433 drives the cast welding pressure plate 434 to move in the vertical direction to press or move away from the battery 9.

[0066] See Figure 4 and Figure 5 A feeding assembly 6 for transferring the jig 2 and the battery 9 between the cast welding drive assembly 43 and the turnover rack 1 is provided on the frame 7. In a preferred embodiment, the feeding assembly 6 includes a feeding plate 61, and the feeding plate 61 is transmission-connected with a feeding drive 62. The feeding drive 62 preferably but only has a feeding linear module, and the slider of the feeding main line module is transmission-connected with the feeding plate 61. The feeding drive 62 drives the feeding plate 61 to slide horizontally between the cast welding rack 431 and the turnover rack 1.

[0067] In some specific embodiments shown, a connector 63 is provided between the feed plate 61 and the jig 2. The connector 63 connects the jig 2 and the feed plate 61, so that the feed plate 61 transfers the jig 2 and the battery 9 to the cast welding rack 431. Specifically, the jig 2 is provided with a connection hole 21. The connector 63 can be a connecting rod 314 or a buckle. The connector 63 overlaps the jig 2 at the connection hole 21. The connector 63 is connected to a connecting drive member, which is preferably, but not limited to, a connecting cylinder. The connecting drive member drives the connector 63 to snap into or out of the connection hole 21.

[0068] When the conveyor mechanism 3 places the battery 9 on the jig 2 via the conveyor clamp 31, the connector 63 overlaps the jig 2 in the connection hole 21. The feed drive 62 drives the feed plate 61 to slide toward the cast welding groove 41. The feed plate 61 and the jig 2 pass through the middle of the cast welding frame 431. The connector 63 disengages the connection hole 21 on the jig 2, and the feed plate 61 is separated from the jig 2. The cast welding frame 431 supports the jig 2 and drives it down into the cast welding groove 41. The battery 9 approaches the cast welding bottom mold 42 and cast welding is performed. After cast welding is completed, the cast welding frame 431 drives the jig 2 and the cast-welded battery 9 away from the cast welding bottom mold 42. The feed assembly 6 then transfers the jig 2 and the cast-welded battery 9 back to the turntable 12.

[0069] See Figure 7 In a preferred embodiment, a pressing block 611 is provided on the feed plate 61. After the battery 9 is cast-welded, the cast-welding frame 431 drives the jig 2 to rise, and the feed drive 62 drives the feed plate 61 to slide to the bottom of the jig 2. The cast-welding pressure plate 434 presses the battery 9 on the pressing block 611. The pressing block 611 can press the electrode group in the battery 9 into the outer shell of the battery 9.
