Description

Technical Field

[0001] This invention belongs to the field of lead-acid battery technology. Specifically, it relates to an automated terminal welding machine. Background Technology

[0002] Currently, the demand for high-capacity batteries in commercial vehicles is surging, while the demand for batteries below 180Ah is gradually decreasing. Driven by market competition, cold-start current ratings are becoming increasingly higher. Using conventional welding methods (fusion of the lead ring and the terminal post), excessively high cold-start current ratings can cause the terminal temperature to rise to its melting point during continuous discharge, leading to terminal post meltdown.

[0003] To ensure that the direct terminal of a tapered terminal battery does not melt during high-current discharge, current production methods use a short, round lead ring cover, meaning the cover does not have an injection-molded tapered lead ring. Molten lead is added to a welding mold, and after cooling and demolding, the positive and negative output terminals are formed. This type of terminal is called a weld overlay terminal.

[0004] Existing terminal cladding equipment uses a lead wire feeding fixture that extrudes and feeds the lead wire forward, adding lead while simultaneously welding (simulating manual welding). This results in long welding times and high temperatures, which can soften the plastic around the lead ring, affecting appearance and airtightness. Furthermore, insufficient cooling of the initial lead-addition area at the bottom can cause molten lead to drip onto the electrode group, resulting in a short circuit between the positive and negative terminals. Two workers are required for welding repair and quality inspection, increasing production costs and reducing efficiency to only 70% of conventional terminal welding production rates. (Ceiling welded terminals have a production efficiency of 900 pieces / 10 hours, while conventional terminal welding has a production efficiency of 1300 pieces / 10 hours.) Summary of the Invention

[0005] The purpose of this invention is to provide an automated welding machine for surfacing terminals, taking into account the special characteristics of the lead ring structure and welding method of the surfacing terminals. This machine ensures the appearance quality of the terminal welding while significantly improving welding efficiency, and does not require additional manual labor for terminal welding repair.

[0006] The technical solution of this invention is as follows: It includes a conveying device, which includes a roller conveyor for conveying batteries to be welded. The roller conveyor has two identical workstations, each welding a terminal block. The conveying device also includes a lifting mechanism for lifting the batteries to be welded at the workstations to a position on the same roller conveyor without interference. Each of the two workstations is equipped with an automatic welding unit, which includes a feeding device and a welding mechanism. The feeding device includes a lead wire guiding conveying platform, which includes an unwinding mechanism, a shearing mechanism, and a clamping mechanism for quantitatively conveying lead wire to the shearing mechanism. The unwinding mechanism includes a lead wire roll holder for mounting the lead wire rolls. The clamping mechanism has a first clamping guide wheel, a second clamping guide wheel, and a third clamping guide wheel on its front side. The first, second, and third clamping guide wheels form a pair of wheels, with the pair consisting of upper wheels. The clamping mechanism consists of a lower pair of wheels that mate with the upper pair of wheels. A synchronizing mechanism is located on the back of the clamping mechanism frame. This synchronizing mechanism includes a drive motor for driving the first synchronizing gear. The axles of the second and third clamping guide wheels pass through the clamping mechanism frame. On one axle of the second clamping guide wheel pair on the back of the clamping mechanism frame, a first synchronizing pulley and a first synchronizing gear are mounted. On the other axle of the second clamping guide wheel pair on the back of the clamping mechanism frame, a third synchronizing pulley and a second synchronizing gear are mounted. On the axle of the third clamping guide wheel pair on the back of the clamping mechanism frame, a second synchronizing pulley and a fourth synchronizing pulley are mounted. The first synchronizing gear meshes with the second synchronizing gear. The first synchronizing pulley is connected to the second synchronizing pulley via a first synchronizing belt. The drive motor is connected to the axles of the pair of wheels using a coupling. The axles are connected to the first synchronizing gear via a key.

[0007] The lifting mechanism includes a base frame located below the raceway. A lifting cylinder is located in the middle of the base frame. A lifting guide post, mounted on the upper end of the lifting cylinder, passes through the middle of the base frame and is positioned in the lifting channel. A lifting positioning sleeve is mounted on the end of the lifting cylinder. Support plates fixed to the upper part of the base frame are located on both sides above the raceway, forming a lifting channel between the two support plates. A flow strip is mounted on the support plates to guide the batteries to be welded. A clamping cylinder is located below the flow strip to clamp the batteries lifted by the lifting cylinder. The clamping cylinder: after the battery to be welded reaches the designated position, it fixes it along its length and is located below the flow strip. The flow strip: guides the battery along its length and prevents scratches on the tank wall; it is located on the support plates on both sides of the raceway. The lifting guide post: lifts the battery to be welded, aligning the terminals with the welding cup; it is located below the raceway. The lifting positioning sleeve: controls the rising height of the lifting guide post and acts as a limit; it is located below the lifting guide post. Lifting cylinder: Controls the lifting guide column to lift the battery to be welded, aligning the terminals with the welding cup, positioned below the roller track. Two flow rails are positioned one above the other; a clamping cylinder works with one flow rail to clamp and position the battery to be welded. The lifting cylinder is a double-piston rod cylinder.

[0008] The lead wire guide conveying channel outlet of the shearing mechanism is equipped with a lead melting structure, which includes a positioning platform, a crucible mounted on the positioning platform, and a flipping cylinder for flipping the crucible.

[0009] During operation, the drive motor sends pulse signals, causing the first synchronous pulley to rotate, which in turn rotates the first synchronous belt. Subsequently, the second synchronous pulley rotates, thus transmitting the rotation to the lower pair of clamping guide wheels (2nd and 3rd clamping guide wheels). Simultaneously, the pulse signals from the drive motor cause the first synchronous gear 19 to rotate, which in turn rotates the second synchronous gear 22. Subsequently, the third synchronous pulley rotates, which in turn rotates the second synchronous belt. Then, the fourth synchronous pulley rotates, thus transmitting the rotation to the upper pair of clamping guide wheels (2nd and 3rd clamping guide wheels).

[0010] The cut lead wire coil is continuously fed through the lead wire guide conveying channel of the shearing mechanism; the lead wire guide conveying channel is located on the side above the crucible, and the cut lead wire slides down by gravity and is guided into the crucible through the lead wire guide conveying channel. The initial angle of the crucible position is adjusted according to the position of the battery terminal to be welded; the initial angle refers to the initial position.

[0011] When the battery to be welded enters the workstation via the roller conveyor, the clamping cylinder fixes the battery to be welded at the workstation, and the lifting mechanism lifts the battery so that the part of the battery to be welded is aligned with the welding mechanism. The welding torch on the welding mechanism melts the matching part to be welded on the welding bowl, and at the same time melts the lead wire roll in the crucible, which is then turned over and poured into the welding bowl for condensation. After the lead wire roll in the crucible melts, the turning cylinder pushes it out, and then the turning cylinder resets. The positioning platform ensures that it can be reset normally before and after turning. After the lifting mechanism descends to the initial position, the clamping cylinder resets. Then the battery to be welded enters the next process via the roller conveyor.

[0012] The welding torch is a plasma arc welding torch. The plasma gas receiving tube releases gas, which is then contacted by the arc igniter to generate a penetrating arc for welding. The welding torch drive motor 1 controls the lifting shaft to move the welding torch up and down, while the welding torch drive motor 2 controls the translation shaft 1 and the translation shaft 2 to move the welding torch back and forth.

[0013] The positioning platform is equipped with a position adjustment component, which includes a lead screw, a rotary handle for driving the lead screw to rotate, and a lead screw nut that cooperates with the lead screw. The upper end of the lead screw nut is fixed to the positioning platform, and the lower end of the lead screw nut is mounted on a guide rail. The rotary handle can adjust the position of the crucible to match the position of the battery terminals of different models to be welded, and is fixed by a limit handle. The rotary handle can be rotated clockwise or counterclockwise manually, which drives the positioning platform to move left and right along the guide rail below it through the fixed rod. After the position is correctly adjusted, the limit handle is pressed, and the gap between the clamping block connected to the limit handle decreases, so that the clamping block and the end of the lead screw are clamped together, restricting the rotation of the rotary handle. A flipping cylinder is installed on the positioning platform, which controls the center of gravity of the crucible through the cylinder connecting rod, so that it flips. When the rotary handle is turned clockwise, the platform moves forward or backward to match the position of the battery terminals of different models to be welded.

[0014] The third clamping guide wheel on the clamping mechanism frame is equipped with a waste material recycling box and a baffle. The baffle is used to control the lead wire roll to be poured into the waste material recycling box. The waste material recycling box is installed and fixed on the lead wire guide conveying platform. When the lead wire roll is after the third clamping guide wheel, the lifting cylinder controls the baffle to be poured into the waste material recycling box. The lifting cylinder is located on the side of the waste material recycling box. The lifting cylinder lifts the tail of the baffle. The front end of the baffle has a groove. During normal production, the lead wire can reach the shearing mechanism through the groove.

[0015] ①The process is as follows: feeding (unwinding machine) →→→ clamping mechanism (upper and lower roller structure, precisely controlled by servo motor) →→→ quantitative cutting mechanism (quick cutting with a cutter) → lead wire conveying (multiple quantitative conveying) →→→ melting in crucible (plasma arc melting) →→→ pouring the liquid solution in the crucible into the terminal welding bowl →→→ proceeding to the next process

[0016] ②Brief description of the process:

[0017] Long lead wire → → → Short lead wire → → → Liquid lead → → → Terminal

[0018] The process involves cutting long lead wires into short lead wires, heating and melting them, pouring the melted wires into a molding fixture on the positive and negative terminals of the battery to cool and solidify, then lifting the fixture and moving the battery forward.

[0019] The drive motor in the synchronization mechanism of this invention achieves precise length positioning and sends pulse signals to continuously convey the lead wire roll in reverse through the second and third clamping guide wheels. The drive motor conveys the lead wire roll three times to the cutter via the first, second, and third clamping guide wheels. The purpose of conveying the lead wire three times is: ① If the lead wire is too long, it will not easily slip into the crucible and will get stuck on the lead wire guide conveying channel 28. ② The crucible 36 has a limited depth, and if the lead wire is too long, it will not melt easily, increasing the welding time. ③ Considering the wear of the cutter and production efficiency, the number of times is set to three. The rotating handle of the position adjustment component of this invention moves the platform forward or backward when the wheel handle is turned clockwise, matching the position of different battery terminal models. The adjustment is flexible and convenient, making the application range of this invention wider. The advantages of this invention are: ① It does not require additional space. ② The terminal welding quality is consistent. ③ No additional manual labor is required for re-welding. ④ The production efficiency can reach that of conventional terminal welding. ⑤ Product changeover is rapid.

[0030] The invention will now be described in further detail with reference to the accompanying drawings.

[0031] like Figure 1 , 2 As shown in Figures 3, 4, and 5, this invention discloses an automated terminal cladding welding machine, comprising a feeding device, a welding device, and a conveying device. The feeding device includes an unwinding mechanism, a clamping mechanism, and a cutting mechanism. The welding device includes a lead melting mechanism and a welding mechanism. The conveying device includes a roller conveyor 12, a lifting mechanism, and a cylinder assembly. The cylinder assembly positions the battery to be welded after it reaches the designated station. The roller conveyor 12 has two stations operating on the same principle. The lead wire guide conveying platform on the feeding device continuously supplies material, achieving automated cladding welding of the positive and negative terminals. One station welds one terminal; a battery has two terminals: a positive terminal and a negative terminal.

[0032] According to the production plan, the operator retrieves the required lead wire roll 1 and installs it on the lead wire roll rack 2. The lead wire roll 1 is then conveyed to the clamping mechanism 3. It passes through the first clamping guide wheel (a pair) 14, the second clamping guide wheel 15, and the third clamping guide wheel 16 on the clamping mechanism 3 until it reaches the shearing mechanism 7.

[0033] The drive cylinder 26 on the shearing mechanism 7 controls the cutter 27 to rise to the shearing position. The drive motor (which is a servo motor) 17 conveys the lead wire roll 1 to the cutter 27 three times via the first, second, and third clamping guide wheels. The purpose of conveying the lead wire roll 1 three times is: ① If the lead wire is too long, it will not easily slip into the crucible and will get stuck on the lead wire guide conveying channel 28. ② The crucible 36 has a limited depth, and if the lead wire is too long, it will not melt easily, increasing the welding time. ③ Considering the wear of the cutter and production efficiency, the number of times is set to 3. A lead wire guide conveying channel 28 is provided on the upper side of the crucible 36. The cut lead wire slides down by gravity and is guided into the crucible 36 through the lead wire guide conveying channel 28. Each time it is conveyed, the cutter 27 falls back and forth to shear the lead wire roll 1. When the lead wire roll 1 is used up after the third clamping guide wheel 16, the lifting cylinder 5 controls the baffle 6 to pour the lead wire roll 1 into the waste material recycling box 4. The waste material recycling box 4 is installed and fixed on the lead wire guide conveyor platform, located in front of the third clamping guide wheel. A lifting cylinder 5 is located on the side of the waste material recycling box 4, supporting the baffle 6. The baffle 6 has a groove at its front end, allowing the lead wire to reach the shearing mechanism during normal production.

[0034] During operation, the lifting cylinder 5 controls its connecting rod to extend, causing the baffle 6 to tilt downwards, thus automatically dropping the tail of the lead wire coil 1 into the waste material recycling box 4. The sheared lead wire coil 1 is continuously fed through the lead wire guide conveying channel 28 on the shearing mechanism 7. The drive motor (which is a servo motor) 17 achieves precise length positioning and sends pulse signals to continuously convey the wire through the reverse rotation of the second and third clamping guide wheels. The drive motor 17 sends pulse signals, causing the first synchronous pulley 18 to rotate, driving the first synchronous belt 20 to rotate, followed by the second synchronous pulley 21, which in turn transmits the power to the lower pair of wheels of the second and third clamping guide wheels for continuous rotation. Simultaneously, the pulse signals sent by the drive motor 17 cause the first synchronous gear 19 to rotate, driving the second synchronous gear 22 to rotate, followed by the third synchronous pulley 23 to rotate, driving the second synchronous belt 24 to rotate, followed by the fourth synchronous pulley, which in turn transmits the power to the upper pair of wheels of the second and third clamping guide wheels for continuous rotation.

[0035] Battery 11 enters the first station via roller conveyor 12. Clamping cylinder 46 fixes battery 11 to this station, and lifting mechanism 10 lifts battery 11 so that the part to be welded aligns with welding mechanism 9. Welding torch 38 on welding mechanism 9 melts the matching part to be welded on welding bowl 37. At the same time, welding torch 38 melts lead wire coil 1 in crucible 36, then flips it over and pours it into welding bowl 37 to solidify. After lifting mechanism 10 descends to its initial position, clamping cylinder 46 resets. Battery 11 then enters the next process via roller conveyor 12.

[0036] like Figure 6As shown, after the lead wire coil 1 inside the crucible 36 melts, the tilting cylinder 35 is pushed out and then reset. The positioning platform 34 ensures normal reset before and after tilting. The rotary handle 31 can adjust the position of the crucible 36 and is fixed by the limiting handle 32. The rotary handle 31 can be rotated clockwise or counterclockwise manually, which drives the positioning platform 34 to move left and right along the guide rail 33 below it through the fixing rod. After the position is correctly adjusted, the limiting handle 32 is pressed to restrict the rotation of the rotary handle 31. The axial movement of the crucible is achieved by rotating the handle, and the limiting handle achieves axial positioning. After the limiting handle is rotated, the gap between the clamping blocks becomes smaller, clamping the clamping blocks and the end of the lead screw, preventing the lead screw from rotating. The rotation of the rotary handle drives the lead screw to rotate, and the contact position between the lead screw nut and the positioning platform converts the rotational force into a horizontal force, moving it on the guide rail. The tilting cylinder 35 is installed on the positioning platform 34, and it controls the center of gravity of the crucible 36 through the cylinder connecting rod 30, causing it to tilt. Rotating the handle 31 clockwise moves the platform forward or backward to match the terminal positions of different battery models.

[0037] like Figure 7 As shown. The welding torch 38 is a plasma arc welding torch. The plasma gas receiving tube 40 releases gas, which, after contact with the arc igniter 39, generates a penetrating arc for welding. The welding torch drive motor (which is a servo motor) 1 controls the lifting shaft 42, driving the welding torch 38 to move up and down. At the same time, the welding torch drive motor (which is a servo motor) 2 controls the translation shaft 1 (44) and the horizontal shaft 2 (45), driving the welding torch 38 to move back and forth, thereby achieving a similar circular motion up and down. The welding torch drive motor 1 is on the support plate on the lifting shaft. The welding torch drive motor 2 is on the side of the parallel shaft support plate.

[0038] like Figure 8 , Figure 9 As shown, the lifting cylinder 50 controls the lifting guide column 48 to lift the battery to be welded, ensuring no interference with the raceway and even load distribution. The lifting positioning sleeve 49 can be adjusted to accommodate batteries of different heights. The lifting positioning sleeve 46 controls the rising height of the lifting guide column, acting as a limit, and is positioned below the lifting guide column.
