Description

Technical Field

[0001] This utility model belongs to the technical field of battery casting and welding equipment, and in particular relates to a fully automatic casting and welding production line for lead-acid batteries. Background Technology

[0002] According to the published patent CN211965887U, a fully automated lead-acid battery casting and welding production line includes a casting and welding system and a handling robot. The casting and welding system includes several casting and welding devices arranged in an arc at equal intervals, all surrounding the handling robot. It also includes a conveyor line and an arranging device. The arranging device arranges the lead-acid batteries conveyed on the conveyor line for the handling robot to grasp and load into the casting and welding system, thus solving the technical problem of manual handling of lead-acid batteries during the casting and welding process. The conveyor line, handling robot, and casting and welding system are closely connected, resulting in high work efficiency. However, the following shortcomings still exist: While the aforementioned equipment can handle and weld battery components using robotic arms, it cannot adjust the components after handling. As a result, the components transported to the production line may be flipped or misaligned, leading to errors during subsequent welding operations such as docking. Therefore, we propose a fully automated lead-acid battery welding production line. Utility Model Content

[0003] The purpose of this utility model is to provide a fully automatic casting and welding production line for lead-acid batteries. By using a limiting mechanism and an adjustment mechanism, the problem of the above-mentioned equipment being unable to adjust the workpieces after being transported, even though the robotic arm can transport and weld the battery workpieces, is solved. As a result, the workpieces transported to the production line may be flipped or misaligned, which leads to errors in subsequent casting and welding operations such as docking.

The main body of the casting and welding equipment is fixedly connected to the top outer wall of the conveyor. A connecting frame is fixedly connected to the top outer wall of the end of the conveyor near the main body of the casting and welding equipment. A limit mechanism is provided on the outer wall of the connecting frame. The limiting mechanism includes a rotating shaft, a worm gear fixedly connected to the outer wall of the rotating shaft, a connecting rod fixedly connected to the outer wall of the end of the rotating shaft away from the worm gear, a plurality of fixed shafts rotatably connected to the inner wall of the end of the connecting rod away from the rotating shaft, a second connecting rod rotatably connected to the outer wall of the plurality of fixed shafts, a second fixed shaft rotatably connected to the inner wall of the end of the plurality of connecting rods away from the fixed shafts, a baffle slidably connected to the outer wall of the second fixed shaft, an arc-shaped groove formed on the inner wall of the end of the plurality of baffles near the second fixed shaft, a fixed rod rotatably connected to the inner wall of the plurality of baffles, a worm rotatably connected to the inner wall of the end of the connecting frame near the worm gear, a plurality of sliding rods rotatably connected to the inner wall of the baffles, a plurality of arc-shaped grooves formed on the inner wall of the end of the connecting frame near the second fixed shaft, a first motor fixedly connected to the outer wall of the worm, the outer wall of the first motor fixedly connected to the outer wall of the connecting frame, and an adjustment mechanism provided on the outer wall of the connecting frame.

[0005] Furthermore, the outer wall of the rotating shaft is rotatably connected to the top outer wall of the connecting frame, the inner wall of the arc-shaped groove is slidably connected to the outer wall of the second fixed shaft, the outer walls of several fixed rods are fixedly connected to the bottom outer wall of the connecting frame, and the outer wall of the worm gear meshes with the outer wall of the worm wheel.

[0006] Furthermore, the adjustment mechanism includes a slide rail, the outer wall of which is fixedly connected to the top of the inner wall of the connecting frame, a motor is fixedly connected to the outer wall of the connecting frame near the slide rail, and a threaded rod is fixedly connected to the bottom output end of the motor via a coupling.

[0007] Furthermore, the outer wall of the threaded rod is threadedly connected to a slider, the inner wall of the slider is slidably connected to the inner wall of the slide rail, the inner wall of the connecting frame away from the slide rail is fixedly connected to a limit shaft, and the inner wall of the slider is fixedly connected to a second limit shaft.

[0008] Furthermore, both the outer wall of the limiting shaft and the outer wall of the second limiting shaft are rotatably connected to a support rod. The inner wall of the support rod is rotatably connected to a third limiting shaft. The inner wall of the connecting frame near the second limiting shaft is provided with several arc-shaped grooves. The inner walls of the several arc-shaped grooves are slidably connected to the outer wall of the second limiting shaft.

[0009] Furthermore, the inner wall of the end of the support rod away from the limiting shaft is rotatably connected to the limiting shaft four, and the outer wall of the limiting shaft four is rotatably connected to the fixing plate.

[0010] Furthermore, an arc-shaped groove four is formed on the inner wall of the fixed plate near the arc-shaped groove three, and the outer wall of the limiting shaft four on the right side is slidably connected to the inner wall of the arc-shaped groove four. A roller is rotatably connected to the inner wall of the fixed plate away from the arc-shaped groove three.

[0011] Furthermore, a detector is fixedly connected to the top of the inner wall of the end of the connecting frame away from the roller, and a controller is fixedly connected to the outer wall of the end of the connecting frame near the motor.

[0012] This utility model has the following beneficial effects: 1. This utility model, by setting an arc-shaped groove inside the baffle, allows the controller to automatically start the first motor when the workpiece is conveyed to the middle of the baffle. The rotation of the first motor drives the worm gear to rotate, which in turn drives the rotating shaft to rotate, causing the connecting rod to rotate. The rotation of the connecting rod drives the fixed shaft to rotate around the rotating shaft. When the fixed shaft moves, it pulls the second connecting rod, causing the second fixed shaft to slide within the arc-shaped groove. This achieves automatic alignment of the battery workpiece before casting and welding, ensuring that the workpiece is accurately positioned on the center line of the conveyor, thus laying a solid foundation for the subsequent precise docking of the casting and welding mold and the formation of the busbar.

[0013] 2. This utility model incorporates a slider within the slide rail. During operation, the workpiece to be processed is placed on the conveyor for transport. When the workpiece is directly below the detector, the detector takes a picture of it. If the workpiece is flipped over, the detector transmits the data to the controller, which automatically starts the motor to rotate and lower the rollers. Since the rollers block the workpiece's forward movement, the system can identify normal and flipped workpieces during battery workpiece transport and flip the flipped workpieces back over to ensure they are placed correctly. This ensures the workpiece enters the casting and welding station in the correct posture, avoiding processing deviations.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-7 As shown, this utility model is a fully automatic casting and welding production line for lead-acid batteries, including a conveyor 1. The top outer wall of the conveyor 1 is fixedly connected to the main body 101 of the casting and welding equipment. A connecting frame 102 is fixedly connected to the top outer wall of the end of the conveyor 1 near the main body 101 of the casting and welding equipment. A limit mechanism 2 is provided on the outer wall of the connecting frame 102. The position of the rotating shaft 201 can be limited by the connecting frame 102, so that it can only rotate on the connecting frame 102 and prevent it from falling off. The limiting mechanism 2 includes a rotating shaft 201. A worm gear 202 is fixedly connected to the outer wall of the rotating shaft 201. A connecting rod 203 is fixedly connected to the outer wall of the end of the rotating shaft 201 away from the worm gear 202. Several fixed shafts 204 are rotatably connected to the inner wall of the end of the connecting rod 203 away from the rotating shaft 201. The fixed shafts 204 can limit the position of the connecting rod 205 to prevent it from falling off, and at the same time allow the connecting rod 205 to rotate around the fixed shafts 204. The connecting rod 205 is rotatably connected to the outer wall of the several fixed shafts 204. A fixed shaft 206 is rotatably connected to the inner wall of the end of the several connecting rods 205 away from the fixed shaft 204. A baffle 207 is slidably connected to the outer wall of the fixed shaft 206. Each baffle 207 has an arc-shaped groove 211 on the inner wall of the end of the several baffles 207 near the fixed shaft 206. The arc-shaped groove 211 can prevent the fixed shaft 206 from jamming when driving the baffle 207. This phenomenon makes the movement of the baffle 207 more stable. The inner walls of several baffles 207 are rotatably connected to fixed rods 208. The inner wall of the connecting frame 102 near the worm wheel 202 is rotatably connected to a worm 209. The inner wall of the baffle 207 is rotatably connected to several sliding rods 210. Since the worm 209 and the worm wheel 202 mesh with each other, the rotation of the worm 209 will drive the worm wheel 202 to rotate, which will in turn cause the rotating shaft 201 to rotate. The inner wall of the connecting frame 102 near the fixed shaft 206 is provided with several arc-shaped grooves 212. The outer wall of the worm 209 is fixedly connected to a first motor 213. The outer wall of the first motor 213 is fixedly connected to the outer wall of the connecting frame 102. The outer wall of the connecting frame 102 is provided with an adjustment mechanism 3. The arc-shaped grooves 212 can limit the movement trajectory of the fixed shaft 206, so that it can only move in a straight line along the direction of the arc-shaped grooves 212.

[0020] The outer wall of the rotating shaft 201 is rotatably connected to the top outer wall of the connecting frame 102. The inner wall of the arc-shaped groove 211 is slidably connected to the outer wall of the fixed shaft 206. The outer walls of several fixed rods 208 are all fixedly connected to the bottom outer wall of the connecting frame 102. The outer wall of the worm gear 209 meshes with the outer wall of the worm wheel 202. The adjusting mechanism 3 includes a slide rail 301, which can limit the movement trajectory of the slider 304, allowing it to move linearly along the direction of the slide rail 301. The outer wall of the slide rail 301 is fixedly connected to the top of the inner wall of the connecting frame 102. A motor 302 is fixedly connected to the outer wall of the connecting frame 102 near the slide rail 301. The bottom output end of the motor 302 is fixedly connected to a threaded rod 303 via a coupling. When the user starts the motor 302, the rotation of the motor 302 can drive the threaded rod 303 to rotate, which in turn can drive the slider 304 to slide linearly within the slide rail 301. The outer wall of the threaded rod 303 is threadedly connected to the slider 304. The inner wall of the slider 304 is slidably connected to the inner wall of the slide rail 301. The inner wall of the connecting frame 102 away from the slide rail 301 is fixedly connected to a limiting shaft 305. The inner wall of the slider 304 is fixedly connected to a limiting shaft 306. The limiting shaft 305 can limit the left end of the support rod 307, allowing it to rotate around the limiting shaft 305.

[0021] Both the outer walls of the limiting shaft 305 and the second limiting shaft 306 are rotatably connected to support rods 307. The inner wall of the support rod 307 is rotatably connected to a third limiting shaft 308. The inner wall of the connecting frame 102 near the second limiting shaft 306 has several arc-shaped grooves 309. The arc-shaped grooves 309 can limit the movement trajectory of the second limiting shaft 306, allowing it to slide horizontally along the direction of the arc-shaped grooves 309. The inner walls of the several arc-shaped grooves 309 are slidably connected to the outer wall of the second limiting shaft 306. The inner wall of the support rod 307 away from the limiting shaft 305 is rotatably connected to a fourth limiting shaft 310. The outer wall of the fourth limiting shaft 310 is rotatably connected to a fixing plate 311. The fixing plate 311 can support the roller 313. The position is fixed so that it can rotate on the fixed plate 311, while preventing the fixed plate 311 from falling off. The inner wall of the fixed plate 311 near the arc groove 309 has an arc groove 312. The outer wall of the right limit shaft 310 is slidably connected to the inner wall of the arc groove 312. The arc groove 312 can limit the movement trajectory of the right limit shaft 308, allowing it to slide linearly along the direction of the arc groove 312. A roller 313 is rotatably connected to the inner wall of the fixed plate 311 away from the arc groove 309. A detector 314 is fixedly connected to the top of the inner wall of the connecting frame 102 away from the roller 313. The detector 314 is a Basler model. The acA2500-14uc is capable of accurately determining whether the orientation of battery terminals, casing markings, etc., is correct by comparing with a preset standard image, ensuring that the workpiece is in the correct position in subsequent casting and welding processes, and avoiding problems such as poor welding caused by incorrect orientation. A controller 315 is fixedly connected to the outer wall of the end of the connecting frame 102 near the motor 302. When the detector 314 detects that the orientation of the battery under the connecting frame 102 does not conform to the standard, it can transmit a signal to the controller 315, at which time the controller 315 can automatically start the motor 302 to rotate.

[0022] One specific application of this embodiment is: When the operator needs to use the equipment, the workpiece to be processed is placed on the conveyor 1 for transport. When the workpiece is directly below the detector 314, the detector 314 can take a picture for inspection. If the workpiece is flipped over, the detector 314 will transmit the data to the controller 315. The controller 315 can automatically start the motor 302 to rotate, causing the roller 313 to drop. At this time, because the roller 313 blocks the workpiece's forward movement, and the conveyor 1 at the bottom is still transporting, the workpiece will be flipped over by the roller 313. Then the controller 315 will start the motor 302 again. Reversing the rotation, when motor 302 rotates, it drives threaded rod 303 to rotate, causing slider 304 to slide closer to motor 302 within slide rail 301. As slider 304 slides, it drives limit shaft two 306, causing it to pull outer support rod 307 closer to motor 302. Since both inner and outer support rods 307 are fixed to limit shaft three 308, and the ends of the inner and outer support rods 307 furthest from motor 302 are respectively limited by limit shaft 305 and limit shaft four 310, the movement of limit shaft two 306 pulls the outer support rod 307, thereby causing the inner support rod 307 to move. The limiting shaft 310 within the arc-shaped groove 312 slides within the arc-shaped groove 312, thereby raising the overall height of the fixing plate 311. When the fixing plate 311 is raised, the roller 313 is also raised, preventing it from obstructing the workpiece. When the workpiece is conveyed to the middle of the baffle 207, the controller 315 automatically starts the first motor 213. The rotation of the first motor 213 drives the worm gear 209 to rotate, causing the worm wheel 202 to rotate. The rotation of the worm wheel 202 drives the rotating shaft 201 to rotate, causing the connecting rod 203 to rotate. The rotation of the connecting rod 203 drives the fixed shaft 204 to rotate around the rotating shaft 201. When the fixed shaft 204 rotates... When shaft 204 moves, it pulls connecting rod 205, causing fixed shaft 206 to slide within arc groove 212. When fixed shaft 206 moves towards the center, it slides within arc groove 211, which in turn drives baffle 207 to gradually rotate around fixed rod 208, making the distance between fixed rods 208 gradually smaller. When the workpiece touches baffle 207, it will gradually adjust to the center position of conveyor 1, making it easier to enter the main body 101 of the casting and welding equipment for processing. Slide rod 210 can reduce the friction when the workpiece contacts baffle 207, making the movement of the workpiece more stable.
