Description

Technical Field

[0001] This invention relates to the field of electrical appliance welding technology, and specifically discloses a fully automatic welding equipment for electrical appliance components. Background Technology

[0002] Currently, resistance spot welding is widely used in the production of electrical components (such as terminals, relay contacts, and small contactor brackets). Traditional resistance spot welding production methods mostly use traditional resistance spot welding machines or semi-automatic resistance spot welding machines, combined with manual labor to complete operations such as loading, positioning, welding, and unloading of components.

[0003] The traditional production methods for the aforementioned electrical and electronic components have several shortcomings. First, existing equipment is mostly semi-automatic spot welding machines, with each process—feeding, sorting, loading, welding, and unloading—being independent, requiring manual handling and coordination between each stage. Second, electrical and electronic components are generally small in size, irregular in shape, and difficult to distinguish between their front and back sides. Traditional equipment lacks an effective feeding mechanism, typically requiring manual selection from the material box and placement onto the welding fixture. This method is not only labor-intensive and inefficient, but also suffers from inconsistent placement, easily leading to positioning deviations that directly affect the accuracy of the weld and product quality. Third, some welding processes require the addition of flux, but current traditional semi-automatic spot welding machines still rely mainly on manual addition, resulting in uneven addition, mismatched timing, and the risk of omissions or over-additions, leading to defects such as incomplete welds and false welds. While some equipment incorporates mechanical feeding mechanisms, such as the bite-roller feeding mechanism, which uses a pair of opposing rotating rollers to compress the flux for forward feeding, these mechanisms suffer from several drawbacks. Firstly, the bite-roller feeding relies on the friction between the flux and the roller surface. When the flux diameter is uneven or the surface is smooth, the flux feeding is prone to slippage, making precise quantitative feeding impossible and leading to severe issues like incomplete or broken welds. Secondly, the flux is susceptible to twisting, piling up, or jamming at the bite-roller inlet, causing feeding interruptions and significantly impacting the continuity and reliability of the welding process. Therefore, this application proposes a fully automated welding equipment for power and electrical components that effectively addresses the aforementioned technical problems and shortcomings. Summary of the Invention

[0004] The present invention aims to solve the problems of low automation, reliance on manual feeding and addition of flux in existing resistance spot welding equipment for electrical components, as well as inaccurate feeding and easy jamming of existing mechanical feeding mechanisms.

[0005] This invention is achieved through the following technical solution: A fully automated welding equipment for electrical components includes a welding platform, on which are mounted a flexible vibratory feeder mechanism, a vision sorting system, a gripping and feeding robot, a positioning welding mechanism, a flux precision feeding mechanism, and a control cabinet with an integrated control system. Wherein: The flexible vibratory feeder mechanism is used to lay out electrical components by high-frequency vibration. The visual sorting system is used to photograph and analyze the flattened parts, determine whether the posture of the parts is correct, and generate coordinate position information. The gripping and loading robot grips the correctly oriented parts based on the generated coordinate position information and transfers them to the positioning and welding mechanism; The positioning and welding mechanism includes a flexible positioning fixture and a welding electrode assembly, which are used to clamp and fix parts and complete automatic welding. The flux precision feeding mechanism is aligned with the positioning welding mechanism and is used to automatically feed flux to the welding point. The control system is electrically connected to the flexible vibratory feeder, the vision sorting system, the gripping and feeding robot, the positioning and welding mechanism, and the flux precision feeding mechanism, and is used to receive feedback information and issue execution commands.

[0006] As a further feature of the above solution, the flux precision feeding mechanism includes a fixed column, an adjustment block at the upper end of the column, a rotatable and adjustable base plate inserted into the adjustment block, and a flux step-by-step pushing component on the base plate.

[0007] As a further provision of the above scheme, the flux step-by-step push assembly includes a first horizontal push cylinder fixedly connected to the base plate. The telescopic end of the first horizontal push cylinder is connected to a first movable block. A second horizontal push cylinder is fixedly installed inside the first movable block. The telescopic end of the second horizontal push cylinder is connected to a second movable block. The upper surfaces of the first movable block and the second movable block are respectively connected to a first channel plate and a second channel plate by springs. The end of the second channel plate away from the first channel plate is connected to a discharge nozzle. The first channel plate, the second channel plate and the discharge nozzle are in the same straight line position, and all three have a guide channel for flux to pass through. The first movable block is provided with a first lifting cylinder, and the second movable block is provided with a second lifting cylinder. The telescopic end of the first lifting cylinder extends upward into the material guide channel of the first channel plate, and the telescopic end of the second lifting cylinder extends upward into the material guide channel of the second channel plate.

[0008] As a further feature of the above scheme, the flexible vibratory feeder, the vision sorting system, and the gripping and loading robot constitute a loading system. The loading system consists of two sets, which are respectively located on the left and right sides of the welding platform.

[0009] As a further feature of the above scheme, a welding platform is provided on the welding stand between the two feeding systems, and the positioning welding mechanism and the flux precise feeding mechanism are located in the center of the welding platform.

[0010] As a further feature of the above solution, the flexible positioning fixture includes a servo-controlled rotary gripper, the output end of which is connected to a telescopic component, the telescopic end of which is connected to a carrier plate, and the upper surface of the carrier plate is provided with a positioning part consisting of a first positioning cylinder, a second positioning cylinder, a third positioning cylinder, and a positioning component connected to the telescopic ends of the three cylinders.

[0011] As a further provision of the above scheme, the welding electrode assembly includes a lifting cylinder fixedly mounted on the upper end of the welding platform, the lower end of the lifting cylinder is connected to an electrode mounting base, and the electrode mounting base is provided with a welding electrode for welding.

[0012] As a further provision of the above scheme, the flexible vibratory feeder feeding mechanism includes a hopper and a vibratory feeder. The vibratory feeder is located at the discharge end of the hopper. The hopper is driven by a lifting device to tilt its discharge end downward, and a baffle plate is provided at the discharge end of the hopper.

[0013] As a further feature of the above solution, the visual sorting system includes a fixed bracket, and an industrial camera with a lens aligned with the vibrating plate is mounted on the upper end of the bracket.

[0014] As a further provision of the above solution, the gripping and feeding robot includes an industrial robot, and the end of the industrial robot is provided with a gripper for gripping and grasping parts in the vibratory feeder.

[0015] The fully automatic welding equipment for power electrical components disclosed in this invention is based on a welding platform, on which a flexible vibratory feeder mechanism, a vision sorting system, a gripping and feeding robot, a positioning welding mechanism, and a flux precision feeding mechanism are integrated, all of which are uniformly scheduled by a control cabinet of an internal integrated control system.

[0016] During operation, the flexible vibratory feeder first lays out batches of electrical components using high-frequency vibration, evenly distributing the previously stacked or disorderly parts within the vibratory feeder. A vision sorting system above then photographs the parts within the vibratory feeder. The control system analyzes the images to determine which parts have the correct orientation (e.g., facing upwards, aligned), and automatically generates their coordinate positions within the feeder. Based on this coordinate information, a gripping robot precisely picks up the correctly oriented parts using its end-effector and transfers them to the flexible positioning fixture of the welding mechanism. The flexible positioning fixture clamps the parts using three positioning cylinders in different dimensions and can adjust the height and tilt angle of the parts as needed to align the welding points with the electrodes.

[0017] For welding processes requiring flux, this equipment is specially equipped with a precise flux feeding mechanism. This mechanism uses a stepping push method: it has two internal channel plates, each with a lifting cylinder underneath. By alternately pressing and releasing the flux, combined with the extension and retraction of the horizontal pushing cylinder, the flux extends forward a fixed length each time, thus precisely delivering the flux to the welding point. This feeding method does not rely on friction and avoids the slippage or jamming problems common in traditional meshing wheel feeding systems.

[0018] During welding, the electrode is adjusted to a suitable height by the lifting cylinder and electrode mounting base, and resistance spot welding is performed on the positioned parts. Throughout the process, the control system receives feedback signals from each mechanism in real time and issues corresponding execution commands to ensure that the feeding, sorting, gripping, feeding, and welding links are connected in an orderly and coordinated manner, thereby realizing the fully automated operation of electrical appliance components from scattered raw materials to welding completion.

[0019] Compared with the prior art, the present invention has the following beneficial effects: The fully automated welding equipment for power and electrical components disclosed in this invention integrates flexible vibratory feeder feeding, vision sorting, robot grasping and feeding, automatic flux feeding, and positioning welding into a single device, all coordinated by a control system. The entire welding process, from scattered parts to finished welded components, requires no manual intervention, solving the problems of disconnected processes and reliance on manual handling in traditional semi-automatic spot welding machines, effectively improving production cycle time and operational continuity.

[0020] The flexible vibratory feeder mechanism in the feeding system of this invention can flatten and unfold small, irregularly shaped electrical components, avoiding jamming and stacking. The vision sorting system automatically identifies whether the component posture is correct and generates coordinate positions, replacing manual visual sorting. The gripping and feeding robot accurately grips and places the components at the welding station according to the coordinates, avoiding the positional deviations caused by manual placement. Through the coordinated work of the above three components, the entire feeding system reduces labor intensity and improves feeding consistency and welding accuracy. In addition, the design of the dual feeding system allows the two systems to operate alternately, effectively matching the welding rhythm of the components and improving production efficiency.

[0021] This invention also employs a step-by-step flux feeding mechanism, which solves the problems of slippage and jamming in traditional feeding methods. Its specially designed step-by-step flux feeding component uses two channel plates to alternately press and a horizontal push cylinder to push the flux step by step. This makes the flux feeding independent of friction, and the length of each push is fixed and controllable, fundamentally avoiding slippage and jamming problems. It ensures that the flux is continuously and accurately delivered to the welding point, effectively solving the welding quality problems caused by inaccurate flux supply, such as cold solder joints and false solder joints.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-9 This application will be described in detail with reference to the embodiments. Example 1

[0026] Example 1 discloses a fully automated welding equipment for electrical components, such as... Figure 1 and Figure 2 As shown, the main body of the welding equipment includes a welding platform 10, a flexible vibratory feeder 20, a vision sorting system 30, a gripping and loading robot 40, a positioning welding mechanism 50, and a control cabinet 60 with an integrated control system. During the automatic welding of electrical components, the flexible vibratory feeder 20 irregularly vibrates a batch of components each time. The vision sorting system 30 then photographs and analyzes the components inside the vibratory feeder. When a component with the correct orientation is detected in the vibratory feeder, the gripping and loading robot 40 precisely grips it and places it on the positioning welding mechanism 50 for automatic welding.

[0027] To improve the overall welding efficiency of the welding equipment, in this embodiment 1, two sets of feeding systems are provided, consisting of a flexible vibratory feeder feeding mechanism 20, a vision sorting system 30, and a gripping and loading robot 40. These systems are respectively mounted on support frames 70 on the left and right sides of the welding platform 10. A welding platform 11 is provided on the welding platform 10 between the two feeding systems, and a positioning welding mechanism 50 is located in the center of the welding platform 11. Furthermore, a control cabinet 60 is located on the side of the welding platform 10. Its integrated control system is electrically connected to the flexible vibratory feeder feeding mechanism 20, the vision sorting system 30, the gripping and loading robot 40, and the positioning welding mechanism 50, enabling it to receive feedback information and issue corresponding execution commands.

[0028] like Figure 3As shown, the flexible vibratory feeder feeding mechanism 20 includes a hopper 21 disposed on the upper surface of the support frame 70. A lifting device is connected to the lower end of the hopper 21. Driven by the lifting device, the dropping end of the hopper 21 automatically tilts downwards to allow parts to slide down automatically. Simultaneously, a baffle plate 22 is provided at the upper end of the dropping end of the hopper 21 to prevent excessive parts from being dropped into the hopper 21 at once. A vibratory feeder 23 is disposed beside the hopper 21 and connected to its dropping end. When parts fall into the vibratory feeder 23, the vibratory feeder 23 starts, generating high-frequency vibrations that cause the parts to vibrate irregularly and lay flat in the vibratory feeder 23, allowing the corresponding visual sorting system 30 to capture images of the parts inside.

[0029] The vision sorting system 30 includes a bracket 31 fixed to a support frame 70. An industrial camera 32 with its lens facing downwards and aimed at the vibratory feeder 23 is mounted on the upper end of the bracket 31. The industrial camera 32 is electrically connected to the control cabinet 60 via a data cable. After the industrial camera 32 takes a picture of the vibratory feeder 23, the picture is preprocessed by the control system. After the preprocessing is completed, the picture is compared and judged to find whether there are correctly oriented parts in the vibratory feeder 23, and the coordinate position information of the part in the vibratory feeder 23 is automatically generated.

[0030] The gripping and loading robot 40 includes an industrial robot, preferably a six-axis robot, with a gripper at its end for gripping and holding workpieces. The gripping and loading robot 40 is connected to the signal output terminal of the control system and adopts servo control. After receiving the control signal, it can actively grip the parts in the vibratory feeder 23 and then place the parts in the flexible positioning fixture 51 of the positioning and welding mechanism 50.

[0031] The positioning welding mechanism 50 in this embodiment 1 includes a flexible positioning fixture 51 disposed on the welding platform 11 and a welding electrode assembly 52 disposed on the upper end of the welding stand 10. Figure 1 and Figure 4As shown, the flexible positioning fixture 51 includes a servo-controlled rotary gripper 511. The output end of the rotary gripper 511 is connected to a telescopic member 512 extending above the welding platform 11. A carrier plate 513 is connected to the telescopic end of the telescopic member 512. The upper surface of the carrier plate 513 is provided with a positioning section consisting of a first positioning cylinder 514, a second positioning cylinder 515, a third positioning cylinder 516, and positioning members 517 connected to their telescopic ends. When the gripping and loading robot 40 places the parts in the positioning section, they can be clamped and fixed by the three positioning cylinders of different dimensions. Before or during welding, the telescopic member 512 adjusts its horizontal height, and the rotary gripper 511 adjusts its horizontal tilt angle, enabling it to perform corresponding welding on various types of parts.

[0032] In addition, the welding electrode assembly 52 includes a lifting cylinder 521 fixedly mounted on the upper end of the welding platform 10. The lower end of the lifting cylinder 521 is connected to a servo-controlled electrode mounting base 522, and a welding electrode 523 for welding is mounted at the output end of the electrode mounting base 522.

[0033] The specific workflow of the fully automatic welding equipment in this embodiment 1 is as follows: First, the control system activates two sets of feeding systems. The lifting devices on the corresponding sides drive the hopper 21 to tilt, causing the electrical components to slide down the discharge end into the vibratory feeder 23. The baffle plate 22 limits the amount of material discharged at one time. The vibratory feeder 23 then starts high-frequency vibration, causing the components to move irregularly within the feeder and gradually spread out.

[0034] Secondly, the industrial camera 32 takes real-time pictures of the components inside the vibratory feeder 23 and transmits the image data to the control system in the control cabinet 60. The control system preprocesses the images and performs feature comparison to determine whether there are components with the correct orientation (e.g., facing upwards and in the same direction). If so, it automatically calculates the precise position of the component in the coordinate system of the vibratory feeder 23 and generates a gripping command.

[0035] Then, based on the received coordinate information, the gripping and feeding robot 40 drives the gripper to move to the corresponding position, accurately grips the correctly oriented parts, and transfers them to the flexible positioning fixture 51 of the positioning and welding mechanism 50. Under the coordinated operation of the left and right feeding systems, the two gripping and feeding robots 40 alternately or synchronously feed materials to the positioning and welding mechanism 50 to match the welding rhythm.

[0036] Next, the first positioning cylinder 514, the second positioning cylinder 515, and the third positioning cylinder 516 in the flexible positioning fixture 51 drive the corresponding positioning components 517 from different dimensions to clamp and fix the parts onto the carrier plate 513. According to the preset welding process requirements, the telescopic component 512 can adjust the height position of the parts, and the rotating clamp 511 can adjust the horizontal tilt angle of the parts so that the welding point is aligned with the electrode 523.

[0037] Finally, the lifting cylinder 521 lowers the welding electrode 523 to the welding height, completing the automatic resistance spot welding of the parts. After welding, the positioning cylinders are released sequentially, and the finished product is removed manually or by a subsequent unloading device. At the same time, the equipment immediately enters the next welding cycle. Through the above continuous cycle operation, this embodiment 1 realizes fully automatic unmanned operation from feeding, sorting, gripping, positioning to welding. Example 2

[0038] This embodiment 2 discloses a flux precision feeding mechanism 80 that is aligned with the positioning welding mechanism 50 and added to the welding platform 11 to meet the special resistance welding requirements, based on the technical solution in embodiment 1. Through this flux precision feeding mechanism 80, flux can be automatically and accurately fed to the welding point during the welding process.

[0039] The similarities between Example 2 and Example 1 will not be repeated here; the differences are as follows: Figures 3-9 As shown. The flux precision feeding mechanism 80 includes a column 81 fixed on the welding platform 11. An adjustment block 82 is fixedly installed at the upper end of the column 81. A rotatable and adjustable base strip seat 83 is inserted into the adjustment block 82. A flux stepping pusher component 84 is installed on the base strip seat 83.

[0040] The flux step-feed assembly 84 includes a first horizontal push cylinder 841 fixedly connected to a base plate 83. The telescopic end of the first horizontal push cylinder 841 is connected to a first movable block 842, and the side end of the first movable block 842 slides against the base plate 83. A second horizontal push cylinder 843 is fixedly disposed inside the first movable block 842, and the telescopic end of the second horizontal push cylinder 843 is connected to a second movable block 844 parallel to the first movable block 842. A first channel plate 845 is connected to the upper surface of the first movable block 842 via a spring. Similarly, a second channel plate 846 is connected to the upper surface of the second movable block 844 via a spring. An outwardly extending nozzle 847 is connected to the end of the second channel plate 846 away from the first channel plate 845. The first channel plate 845, the second channel plate 846, and the nozzle 847 are aligned in a straight line, and each of them has a guide channel 840 for flux to pass through.

[0041] Finally, a first lifting cylinder 848 is provided in the first movable block 842, and a second lifting cylinder 849 is provided in the second movable block 844. The telescopic end of the first lifting cylinder 848 extends upward into the material guide channel 840 of the first channel plate 845 to press the flux. Similarly, the telescopic end of the second lifting cylinder 849 extends upward into the material guide channel 840 of the second channel plate 846 to press the flux.

[0042] In the operation of the flux stepping push assembly 84 disclosed in Embodiment 2, when the flux at the discharge end of the nozzle 847 is exhausted, the second lifting cylinder 849 extends and the first lifting cylinder 848 retracts. The telescopic end of the second lifting cylinder 849 extends into the guide channel 840 of the second channel plate 846 to press and fix the flux. Subsequently, the second horizontal pushing cylinder 843 extends, pushing the second movable block 844, the second channel plate 846, and the nozzle 847 towards the welding point a set distance. Then, the first lifting cylinder 848 extends, and its telescopic end extends into the guide channel 840 of the first channel plate 845 to press and fix the flux, while the second lifting cylinder 849 retracts to release the pressing and fixing of the flux in the second channel plate 846. Next, the second horizontal push cylinder 843 shortens, retracting the second movable block 844, the second channel plate 846, and the discharge nozzle 847 backward. During the retraction, the flux remains stationary due to the fixation of the first lifting cylinder 848. Therefore, after the retraction is complete, a set length of fresh flux will extend from the discharge nozzle 847 for use in the next resistance welding. Finally, during subsequent resistance welding, the first horizontal push cylinder 841 pushes the entire flux stepping push assembly 84 slowly towards the welding point, achieving precise flux supply and effectively ensuring the smooth progress of the entire welding process.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
