Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The welding mechanism includes a supporting plate 4 and a laser welding machine 7; the supporting plate 4 is horizontally fixedly connected to one side of the top of the main body 1, and an electric guide rail 5 is horizontally installed on the supporting plate 4, and a battery positioning frame 6 is slidably connected to the electric guide rail 5. When the lead-acid battery main body 45 needs to be welded with electrode plates, the lead-acid battery main body 45 is turned upside down in the battery positioning frame 6, so that the electrode ear slot of the lead-acid battery main body 45 faces downward; a connecting protrusion 39 is provided at the bottom of the battery positioning frame 6, and an insertion hole 40 is opened on the connecting protrusion 39, and the insertion hole 40, the electrode ear slot and the casting cavity 9 are aligned up and down, and the two sides of the insertion hole 40 are connected to a linkage sliding mechanism, and the linkage sliding mechanism is connected to a linkage clamping block 28, and a connecting spring 30 is horizontally connected to the linkage clamping block 28, and a pressure block 31 is connected to the end of the connecting spring 30. The movable sliding mechanism is connected with the demoulding and pushing mechanism. When the linkage clamping blocks 28 are linked and squeezed on the paired welding electrode ears, the pressure block 31 contacts the welding electrode ears, and the connecting spring 30 is in a compressed state. When the welding electrode ears become molten due to the welding action, the connecting spring 30 relies on the elastic force to cause the pressure block 31 to further squeeze the softened end of the welding electrode ear, so as to facilitate the fusion welding of the ends of the paired welding electrode ears.

[0031] The demoulding and ejecting mechanism includes a hydraulic telescopic rod 17 and a demoulding movable top block 37; the hydraulic telescopic rod 17 is vertically fixedly connected to the inner bottom of the casting groove 2, the telescopic end of the hydraulic telescopic rod 17 is horizontally fixedly connected to the linkage top plate 18, the upper side of the linkage top plate 18 is vertically fixedly connected to the ejecting connecting rod 38, the demoulding movable top block 37 is fixedly connected to the top of the ejecting connecting rod 38, the demoulding movable top block 37 is slidably connected to the inner bottom of the casting cavity 9, the contraction control switch of the hydraulic telescopic rod 17 and the start switch of the laser welding machine 7 are linked, that is, the two are triggered synchronously during operation.

[0032] The linkage sliding mechanism includes a linkage push rod 24 and a linkage steel wire 23; the linkage push rod 24 is vertically fixedly connected to the linkage top plate 18, and the linkage push rod 24 longitudinally penetrates the top of the left wall of the casting groove 2. A vertical sliding cavity 19 is provided on one side of the battery positioning frame 6, and the linkage push rod 24 and the vertical sliding cavity 19 are aligned up and down. An electromagnet 20 is installed on the inner top of the vertical sliding cavity 19, and the electromagnet 20 is equipped with a control switch. A sliding iron column 21 is slidably connected to the inner side of the vertical sliding cavity 19. When the electromagnet 20 is in a power-off state, the sliding iron column 21 slides down to the outside of the bottom of the vertical sliding cavity 19 by gravity, and a limiting protrusion is provided on the top of the sliding iron column 21 to prevent the sliding iron column 21 from detaching from the vertical sliding cavity 19. A conductive rotating rod 22 is horizontally rotatably connected to the bottom outer wall of the battery positioning frame 6 obliquely below the position of the cavity 19, and a horizontal sliding cavity 41 is horizontally opened on both sides of the insertion hole 40. A fixed pulley 27 is fixedly installed inside the horizontal sliding cavity 41, and a return spring 26 is also connected to the horizontal sliding cavity 41. The end of the return spring 26 is connected to the linkage clamping block 28. One end of the linkage steel wire 23 is connected to the sliding iron column 21, and the other end penetrates into the horizontal sliding cavity 41 and is connected to the linkage clamping block 28. The linkage clamping block 28 is slidably connected in the horizontal sliding cavity 41, and the end of the linkage steel wire 23 close to the linkage clamping block 28 is bypassed from the fixed pulley 27, and the end of the linkage steel wire 23 close to the sliding iron column 21 is bypassed from the bottom of the conductive rotating rod 22.

[0033] The linkage rotation mechanism includes a rack 29 and a rotating shaft body 35; the rack 29 is horizontally connected to the bottom of the linkage clamping block 28, and a strip-shaped opening 25 is horizontally opened at the bottom of the transverse sliding cavity 41. A main gear 32 is rotatably connected below the position of the strip-shaped opening 25, and the rack 29 is meshed with the main gear 32. The rotating shaft body 35 is horizontally rotatably connected below the insertion hole 40. A torsion spring 36 is connected between the rotating shaft body 35 and the movable laser welding head 33. The movable laser welding head 33 is rotatably sleeved on the rotating shaft body 35, that is, the movable laser welding head 33 can rotate around the rotating shaft body 35. A linkage gear 34 is coaxially connected to the rotating shaft body 35, and the linkage gear 34 is meshed with the main gear 32. Before the welding electrode ear cast in the casting cavity 9 is demolded and lifted up, the movable laser welding head 33 deviates from the position directly below the insertion hole 40 to prevent the welding electrode ear from being hindered from rising through the insertion hole 40.

[0034] When it is necessary to demould the welding electrode ear cast in the casting mold 8 and connect it to the electrode ear slot on the lead-acid battery body 45, first, the lead-acid battery body 45 is turned upside down in the battery positioning frame 6, so that its electrode ear slot faces downward, and then the electric guide rail 5 is controlled to run, driving the battery positioning frame 6 to move horizontally to just above the casting groove 2, and then the hydraulic telescopic rod 17 is controlled to extend upward. During this process, the hydraulic telescopic rod 17 drives all the pushing connecting rods 38 to rise upward through the linkage top plate 18, so that the pushing connecting rod 38 causes the demoulding movable top block 37 at the bottom of the casting cavity 9 to slide and rise upward, thereby lifting the welding electrode ear formed in the casting cavity 9, and the lifted welding electrode ear rises through the insertion hole 40 and is inserted into the electrode When the hydraulic telescopic rod 17 pushes the welding electrode ear upward in the ear slot, the linkage push rod 24 rises synchronously therewith. When the demoulding-lifted welding electrode ear rises and is inserted into the electrode ear slot, the linkage push rod 24 contacts the sliding iron column 21. Then the sliding iron column 21 slides toward the top of the vertical sliding cavity 19 due to the pushing. During this process, the sliding iron column 21 pulls the linkage steel wire 23. The linkage steel wire 23 pulls the linkage clamping block 28 to slide toward the center of the insertion hole 40 by the steering effect of the conductive rotating rod 22 and the fixed pulley 27, so that it is convenient to clamp the paired welding electrode ears that are inserted into the insertion hole 40 together by relying on the pressure block 31. During the lateral sliding process of the linkage clamping block 28, the linkage clamping block 28 drives the main gear 32 to rotate by relying on the rack 29. The wheel 32 drives the linkage gear 34 to rotate. When the movable laser welding head 33 does not hit the welding electrode ear, the movable laser welding head 33 rotates synchronously with the linkage gear 34. When the movable laser welding head 33 hits the end surface of the welding electrode ear, since the movable laser welding head 33 can rotate around the rotating shaft body 35, the rotating shaft body 35 can still rotate in linkage after the movable laser welding head 33 is blocked and stopped. During this process, the torsion spring 36 generates a rebound force. When the welding electrode ear is fully inserted into the electrode ear slot of the lead-acid battery body 45, one end of it is just in the insertion hole 40. At this time, the movable laser welding head 33 is separated from the end surface of the welding electrode ear, and then rotates and docks to the end of the paired welding electrode ears to be welded by relying on the rebound force of the torsion spring 36. Finally, the control The hydraulic telescopic rod 17 is retracted to drive the demoulding movable top block 37 to reset. During this process, the sliding iron column 21 relies on the energized electromagnet 20 to generate magnetic adsorption, thereby keeping the linkage steel wire 23 in a taut state, causing the linkage clamping block 28 to maintain the state of clamping the welding electrode ear, and when the hydraulic telescopic rod 17 is retracted, the laser welding machine 7 is started synchronously, so that the paired welding electrode ears that need to be welded together at adjacent positions on the battery body are clamped together synchronously during the demoulding process of the welding electrode ear, and the linkage movable laser welding head 33 is in place, so as to facilitate direct welding. When the welding electrode ear has a molten body due to the welding action, the connecting spring 30 relies on the elastic force to cause the pressure block 31 to further squeeze the softened end of the welding electrode ear.It is convenient to fuse and weld the ends of the paired welding electrode ears together, thus improving production efficiency.

[0035] An air suction mechanism is arranged in the main body 1, and the air suction mechanism includes a piston cylinder 14; a plurality of piston cylinders 14 are evenly distributed around the main body 1, the top of the piston cylinder 14 is the air port end, and a piston block 15 is slidably connected to the inner side of the piston cylinder 14, and an air suction pipe 10 is distributed around the periphery of the main body 1, and the upper end of the air suction pipe 10 is the air suction end, which extends to the edge of the casting groove 2, and the bottom end of the air suction pipe 10 is connected to the top of the piston cylinder 14 at the same side, and a linkage rod 16 is connected to the bottom of the piston block 15, and the end of the linkage rod 16 is bent and connected to the linkage top plate 18, and a one-way exhaust mechanism is connected to the top of each piston cylinder 14.

[0036] The one-way exhaust mechanism includes a first one-way air valve 13 and a second one-way air valve 42; the first one-way air valve 13 is installed at the top of the air port end of the piston cylinder 14, and the first one-way air valve 13 can only allow the air flow to flow out of the piston cylinder 14, but not in. An annular connecting pipe 12 is connected between the first one-way air valves 13 at each position of the piston cylinder 14, and a conductive pipe 11 is horizontally connected to the right side of the annular connecting pipe 12, and the conductive pipe 11 extends from the main body 1, and the end of the conductive pipe 11 is used to be connected to the exhaust gas and harmful gas treatment equipment; the second one-way air valve 42 is installed on the right side of the air port end of the piston cylinder 14, and the intake pipe 10 is connected to the second one-way air valve 42, and the second one-way air valve 42 can only allow the air in the intake pipe 10 to enter the piston cylinder 14, but not from the piston cylinder 14 into the intake pipe 10.

[0037] Whenever the hydraulic telescopic rod 17 is extended upward to demould the welding electrode ear, the linkage top plate 18 connected to the telescopic end of the hydraulic telescopic rod 17 drives the linkage rod 16 to rise. During this process, the linkage rod 16 causes the piston block 15 to press toward the top of the piston cylinder 14 to press out the original gas in the piston cylinder 14. When the welding electrode ear is connected to the lead-acid battery body 45 and welding is performed, the contraction control switch of the hydraulic telescopic rod 17 and the start switch of the laser welding machine 7 are synchronously triggered, so the hydraulic telescopic rod 17 is in a state of being pressed upward to demould the welding electrode ear. 17 performs a contraction movement, during which the linkage top plate 18 pulls the piston block 15 downward through the linkage rod 16, causing the gas port end at the top of the piston cylinder 14 to inhale. Since the suction pipe 10 connected to the gas port end at the top of the piston cylinder 14 is distributed around the periphery of the main body 1 and extends to the edge of the casting groove 2, the harmful gas generated during the welding process can be absorbed and inhaled into the piston cylinder 14, and when the hydraulic telescopic rod 17 is extended for demoulding movement next time, the inhaled harmful gas is directly pressed out from the piston cylinder 14.

[0038] The working principle of the present invention is as follows: first, the electrode metal melt casting assembly 3 is used to inject the casting electrode plate metal melt material into the casting mold 8 in the casting tank 2, and the material is distributed in the casting cavity 9. Since the general lead-acid battery body 45 is divided into multiple module units, the electrode ends of each module unit need to be installed with welding electrode ears, and after the module units are spliced ​​together, the adjacent welding electrode ears between the module units need to be welded together. Therefore, two casting cavities 9 are distributed at the same position on the casting mold 8 for casting two welding electrode ears on adjacent battery module units.

[0039] After the welding electrode ear is cooled and formed, the lead-acid battery body 45 is turned upside down in the battery positioning frame 6, so that the electrode ear slot is facing downward, and then the electric guide rail 5 is controlled to run, driving the battery positioning frame 6 to move horizontally to just above the casting groove 2, and then the hydraulic telescopic rod 17 is controlled to extend upward. During this process, the hydraulic telescopic rod 17 drives all the pushing connecting rods 38 to rise upward through the linkage top plate 18, so that the pushing connecting rod 38 causes the demoulding movable top block 37 at the bottom of the casting cavity 9 to slide and rise upward, thereby lifting the welding electrode ear formed in the casting cavity 9, and the lifted welding electrode ear rises through the insertion hole 40 and is inserted into the electrode ear slot. When the hydraulic telescopic rod 17 pushes the welding electrode ear upward, the linkage top rod 24 is synchronously moved. When the welding electrode ear lifted by the demoulding is lifted and inserted into the electrode ear slot, the linkage push rod 24 contacts the sliding iron column 21, and then the sliding iron column 21 slides toward the top of the vertical sliding cavity 19 due to the push. During this process, the sliding iron column 21 pulls the linkage wire 23, and the linkage wire 23 relies on the steering effect of the conductive rotating rod 22 and the fixed pulley 27 to pull the linkage clamping block 28 to slide toward the center of the insertion hole 40, so that it is convenient to rely on the pressure block 31 to clamp the paired welding electrode ears that pass through the insertion hole 40 together. During the lateral sliding process of the linkage clamping block 28, the linkage clamping block 28 relies on the rack 29 to drive the main gear 32 to rotate, and the main gear 32 drives the linkage gear 34 to rotate. When the movable laser welding head 33 does not contact the welding electrode When the electrode ear is on the pole ear, the movable laser welding head 33 rotates synchronously with the linkage gear 34. When the movable laser welding head 33 hits the end face of the welding electrode ear, since the movable laser welding head 33 can rotate around the rotating shaft body 35, after the movable laser welding head 33 is blocked and stopped, the rotating shaft body 35 can still rotate in conjunction. During this process, the torsion spring 36 generates a rebound force. When the welding electrode ear is fully inserted into the electrode ear slot of the lead-acid battery body 45, one end of it is just in the insertion hole 40. At this time, the movable laser welding head 33 is separated from the end face of the welding electrode ear, and then relies on the rebound force of the torsion spring 36 to rotate and dock to the end of the paired welding electrode ears to be welded. Finally, the hydraulic telescopic rod 17 is controlled to contract to drive the demoulding movable top block 37 to reset. During this process, the sliding iron column 21 relies on the energized electromagnet 20 to generate magnetic adsorption, thereby keeping the linkage steel wire 23 in a taut state, so that the linkage clamping block 28 maintains the state of clamping the welding electrode ear, and when the hydraulic telescopic rod 17 contracts, the laser welding machine 7 is started synchronously, so that the paired welding electrode ears that need to be welded together at adjacent positions on the battery body are clamped together synchronously during the demoulding process of the welding electrode ear, and the linkage movable laser welding head 33 is in place, so as to facilitate direct welding. When the welding electrode ear has a molten body due to the welding action, the connecting spring 30 relies on the elastic force to cause the pressure block 31 to further squeeze the softened end of the welding electrode ear, so as to facilitate the fusion and welding of the ends of the paired welding electrode ears, thereby improving production efficiency;

[0040] Whenever the hydraulic telescopic rod 17 is extended upward to demould the welding electrode ear, the linkage top plate 18 connected to the telescopic end of the hydraulic telescopic rod 17 drives the linkage rod 16 to rise. During this process, the linkage rod 16 causes the piston block 15 to press toward the top of the piston cylinder 14 to press out the original gas in the piston cylinder 14. When the welding electrode ear is connected to the electrode ear groove 46 on the lead-acid battery body 45 and welding is performed, the contraction control switch of the hydraulic telescopic rod 17 and the start switch of the laser welding machine 7 are synchronously triggered. Therefore, the hydraulic telescopic rod 17 contracts during the welding process. During this process, the linkage top plate 18 is The piston block 15 is pulled downward by the linkage rod 16, so that the air port end at the top of the piston cylinder 14 is sucked. Since the air intake pipe 10 connected to the air intake end at the top of the piston cylinder 14 is distributed around the periphery of the main body 1 and extends to the edge of the casting groove 2, the harmful gas generated during the welding process can be absorbed and sucked into the piston cylinder 14. When the hydraulic telescopic rod 17 is extended for demolding movement next time, due to the presence of the first one-way air valve 13 and the second one-way air valve 42, the inhaled harmful gas can be discharged from the annular connecting pipe 12 as much as possible, and can be inhaled from the air intake pipe 10 as much as possible to ensure one-way conduction of the gas.
