Description

Technical Field

[0001] The present invention relates to the technical field of welding device structures, and particularly to a fully automatic battery welding device. Background Art

[0002] The welding of lead-acid batteries, especially the welding of the bus bar terminals of lead-acid batteries used in electric vehicles, refers to melting and then connecting in series the positive plates in the battery electrode group and the negative plates of adjacent battery cells to form an integrated bus bar. Initially, manual welding was used, where the electrode lugs of the plates were melted by high-temperature combustion of a gas, solder was added, and then it was cooled and formed to achieve the welding of the bus bar. With the improvement of the automation level, currently, the casting welding method is generally used in the market, in combination with automatic or semi-automatic welding machines, to achieve the welding of battery bus bars. The casting welding method is to heat and melt alloy lead into a liquid state in a lead pot, add the liquid lead into the welding die cavity, then place the battery upside down, insert the electrode lugs downward into the lead liquid cavity, and melt the plates into one body to achieve the welding of the bus bar terminals.

[0003] When the existing fully automatic battery welding device welds a battery, it needs to stagnate for a period of time under the welding structure. During the conventional automated production process, the feeding end will always perform feeding, and the subsequent battery will push the previous one continuously for feeding. However, due to the time required for battery welding, the subsequent battery will continuously squeeze the previous one, resulting in a gradually increasing extrusion force between the batteries, and thus it is difficult to avoid certain safety hazards for the batteries due to extrusion.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the following will describe the specific implementation manners of the present invention in detail with reference to the drawings in the specification.

[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0030] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments alone or selectively.

[0031] Next, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be locally enlarged out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0032] Embodiment 1:

[0033] Refer to Figure 1 - Figure 6 , which is an embodiment of the present invention, provides a fully automatic battery welding device, including a main body unit 100, a buffer conduction unit 200, and a steering adjustment unit 300.

[0034] Among them, the main body unit 100 includes a workbench 101 and an adjustment box 102 fixedly connected to the lower surface of the workbench 101. A blanking guide rail 303 is fixedly connected to one side of the workbench 101;

[0035] Next, the feeding adjustment unit 200 includes a lifting frame 216 fixedly connected to the lower surface of one side of the workbench 101 and a shaft plate 218 fixedly connected to the inner surface of the adjustment box 102. A conveying frame 206 is fixedly connected to one side of the lifting frame 216. A conveying roller 209 is rotatably connected in the conveying frame 206 through a shaft rod. One side of the conveying roller 209 is in contact with a rubber brake block 208, and the inner diameter dimension of one side of the rubber brake block 208 matches the inner diameter dimension of the conveying roller 209;

[0036] Finally, the driving blanking unit 300 includes a load-bearing frame 301 fixedly connected to the upper surface of the workbench 101 and a driving mechanism 302 slidably connected to the upper surface of the workbench 101. A material frame 304 is fixedly connected to one side of the workbench 101, and a chute is provided on the upper surface of the workbench 101, and a fixed guide rail 305 is fixedly connected in the chute.

[0037] Furthermore, a placement plate 202 is slidably connected to the outer surface of the fixed guide rail 305. The placement plate 202 is fixedly connected to the upper surface of the workbench 101. A first guide rail 203 is fixedly connected to the upper surface of the placement plate 202. A limiting elastic piece 227 is fixedly connected in the first guide rail 203. A battery body 103 is placed on the upper surface of the placement plate 202. Among them, through the elastic piece built in the first guide rail 203, when the electric cylinder 205 releases the push on the reciprocating slider 213, it slightly blocks and buffers the reciprocating slider 213 to prevent violent collision when the reciprocating slider 213 retracts.

[0038] Further, an electric cylinder 205 is fixedly connected to one side of the workbench 101. A push plate 204 is fixedly connected to the side of the electric cylinder 205 close to the placement plate 202. A T-shaped block 211 is slidably connected inside the lifting frame 216. A lifting plate 210 is fixedly connected to the upper surface of the T-shaped block 211. A limiting slider 212 is slidably connected to one side of the lifting plate 210. A reciprocating slider 213 is slidably connected to the upper surface of the lifting plate 210. Among them, the reciprocating slider 213 is connected to one side of the lifting plate 210 through a spring, and the outlet size above the workbench 101 is adapted to the outer diameter size of the reciprocating slider 213. Further, during the rising process of the lifting plate 210, the limiting slider 212 is used to contact the lower surface of the workbench 101, so that the lifting plate 210 will not move synchronously with the reciprocating slider 213.

[0039] Working principle: By using the force-bearing plate 201, the placement plate 202, the first guide rail 203, the push plate 204, the electric cylinder 205 and the conveying frame 206, after the battery body 103 rises, the electric cylinder 205 pushes the battery body 103 onto the placement plate 202 on the side of the driving mechanism 302. Furthermore, the driving mechanism 302 drives the placement plate 202 to move on the upper surface of the workbench 101, so as to perform welding processing on it;

[0040] By using the reset gear 217, the shaft plate 218, the limiting rod 219, the transmission rod 220, the guide rail block 221 and the push rod 222, when the reset gear 217 is driven, the reset gear 217 will push the transmission rod 220. Furthermore, the guide block 228 is pushed through the transmission rod 220. The movement of the guide block 228 will carry and push the push rod 222, so that the push rod 222 transmits to the connecting block 215, and the rubber brake block 208 brakes the conveying roller 209. Furthermore, when the equipment is welding, the battery body 103 at the rear will not continue to be fed and squeezed, so as to improve the welding effect of the equipment to a certain extent;

[0041] By using the load-bearing frame 301, the driving mechanism 302, the blanking guide rail 303, the material frame 304 and the fixed guide rail 305, the structure above the workbench 101 performs welding and transportation processing on the battery body 103, and transports and collects the welded battery body 103 through the blanking guide rail 303.

[0042] Embodiment 2:

[0043] Refer to Figure 4 - Figure 6, compared with the first embodiment, the difference lies in that: a reset gear 217 is rotatably connected in the shaft plate 218, and a coil spring is fixedly connected in the reset gear 217, one side of the reset gear 217 is rotatably connected to a transmission rod 220, and the other end of the transmission rod 220 is rotatably connected to a guide block 228, a moving block 226 is fixedly connected to the lower surface of the guide block 228, and the moving block 226 is slidably connected to the guide rail block 221, one side of the guide block 228 contacts with a push rod 222, one side of the push rod 222 is fixedly connected to a connecting block 215, and one side of the connecting block 215 is fixedly connected to one side of the rubber brake block 208, wherein the push rod 222 is moved to transmit and drive the connecting block 215, and further, the rubber brake block 208 contacts one side of the transmission roller 209, thereby braking it.

[0044] Furthermore, a sliding frame 207 is fixedly connected to one side of the conveying frame 206, the outer surface of the rubber brake block 208 is slidably connected in the sliding frame 207, one side of the rubber brake block 208 is fixedly connected to the fixed block 214, one side of the connecting block 215 is fixedly connected to one side of the fixed block 214, and one side of the reset gear 217 is in contact with a seesaw 224, wherein, through the setting of the seesaw 224 and the fixed shaft block 225, the seesaw 224 can quickly toggle the reset gear 217 when subjected to force.

[0045] Furthermore, the outer surface of the seesaw 224 is rotatably connected to a fixed shaft block 225, and the upper surface of the fixed shaft block 225 is fixedly connected to the lower surface of the workbench 101, and the upper surface of the seesaw 224 away from the reset gear 217 is fixedly connected to a transfer plate 223, and a force plate 201 is arranged on the upper surface of the transfer plate 223, and the lower surface of the workbench 101 is fixedly connected to a limiting rod 219, and the transfer plate 223 is sleeved in the limiting rod 219, wherein the pressure borne by the force plate 201 is transferred to one side of the seesaw 224 through the transfer plate 223, so that one side of the seesaw 224 is lowered and the other side is raised, thereby performing a toggle adjustment process on the reset gear 217.

[0046] Working principle: First, in the battery loading trigger stage, when the battery body 103 is pushed by the push plate 204 to the welding station, its gravity acts on the force-receiving plate 201, is transmitted to the transfer plate 223, and drives the rocker 224 to rotate around the fixed shaft block 225. Through the lever effect of the rocker 224, the transfer plate 223 is pressed down, causing the end of the rocker 224 far from the reset gear 217 to lift, pushing the reset gear 217 to rotate counterclockwise, compressing the helical spring inside it to store energy. In the linked braking execution stage, when the reset gear 217 rotates, it drives the transmission rod 220 to move towards the guide block 228. The guide block 228 slides along the guide rail block 221, pushing the push rod 222 to move horizontally. The push rod 222 pulls the rubber brake block 208 through the connecting block 215 to press tightly against the side wall of the conveyor roller 209, using friction to stop the rotation of the conveyor roller 209, blocking the subsequent battery loading channel. At the same time, the sliding frame 207 of the rubber brake block 208 is used in cooperation with the fixed block 214 to ensure no deviation during the braking process; the limiting rod 219 restricts the vertical movement range of the transfer plate 223 to prevent overload;

[0047] Secondly, after welding is completed, the driving mechanism 302 removes the battery from the welding station, the pressure on the force-receiving plate 201 is released, the helical spring releases energy to drive the reset gear 217 to rotate clockwise, the transmission rod 220 retracts to make the guide block 228 move in the opposite direction, and the push rod 222 drives the rubber brake block 208 to disengage from the conveyor roller 209. The conveyor roller 209 resumes rotation to continue transporting subsequent batteries. The limiting slider 212 of the lifting plate 210 contacts the lower surface of the workbench 101 to ensure that the lifting plate 210 only moves vertically up and down and does not move horizontally synchronously with the reciprocating slider 213, maintaining the stability of the loading rhythm;

[0048] Finally, the flexible contact of the rubber brake block 208 avoids damage to the surface of the conveyor roller 209, and the energy storage of the helical spring ensures the rapid reset of the conveyor system after the braking is released. This design effectively eliminates the risk of battery stacking and extrusion to a certain extent.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
