[0001] The present invention relates to the field of welding technology, in particular to an intelligent welding device for electromechanical equipment. Background Art

[0002] In modern industrial manufacturing, electromechanical equipment, with its complex and diverse characteristics, plays a vital role. This type of equipment ranges from precision instruments to large-scale industrial machinery, and its manufacturing process requires high levels of process precision and technical expertise.

[0003] In the manufacturing process of electromechanical equipment, welding is a critical step in connecting and securing components. Its quality directly impacts the overall performance and reliability of the equipment. Welding operations involve a wide variety of workpiece types, including but not limited to thin-plate structural components and base supports. These workpieces often have varying thicknesses and geometries, presenting diverse challenges to the welding process.

[0004] To enhance the versatility and flexibility of welding operations, many welding equipment systems are currently equipped with magnetic positioning devices. However, existing magnetic positioning technologies often utilize an array of magnetic blocks. While this fixed layout can achieve initial workpiece positioning to a certain extent, it often struggles to achieve precise magnetic positioning for workpieces with complex shapes and varying sizes. The fixed position of the magnetic blocks limits their adaptability to different workpieces, potentially causing them to wobble during welding, which in turn affects welding quality and efficiency.

[0005] Furthermore, traditional welding equipment also has significant shortcomings in path planning. Currently, welding path planning often relies on manual operation, which not only requires operators to have extensive experience and superb skills, but is also inefficient and difficult to adapt to the needs of large-scale, high-efficiency production.

[0006] Therefore, it is necessary to provide an intelligent welding device for electromechanical equipment to solve the above problems. Summary of the Invention

[0010] Preferably, the magnetic control positioning assembly includes: a mounting groove, in which a spiral track is installed; wheel grooves spaced apart on the spiral track, in which a rotating wheel is rotatably arranged; a slide seat, which is slidably arranged on the spiral track and driven by the rotating wheel; and a magnetic attraction assembly, which is arranged on the slide seat.

[0011] Preferably, the magnetic attraction assembly includes: a screw, which is rotatably arranged in the slide, and the extension line of the screw coincides with the center of the spiral track; a nut seat, which is limitedly slidably arranged on the slide and is transmission-connected to the screw; and a receiving groove, which is opened on the nut seat and is used to accommodate the magnetic control block.

[0012] Preferably, a magnet is embedded in the accommodating groove, and the magnet and the magnetic control block after power is supplied have opposite polarities and repel each other.

[0013] Preferably, a spring for supporting the magnetic control block is connected between the accommodating groove and the magnetic control block, and the spring and the magnetic control block are configured so that when the magnetic control block is not powered, the magnetic control block can overcome the supporting force of the spring and be adsorbed on the magnet, and at this time, the upper surface of the magnetic control block is not higher than the upper surface of the accommodating groove.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, and this is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0020] Example: Please refer to Figure 1-Figure 7 In an embodiment of the present invention, an intelligent welding device for electromechanical equipment is provided, comprising: A transmission device 1, the transmission device 1 is used to transmit a first carrier plate 4 and a second carrier plate 5, the first carrier plate 4 is used to carry a first workpiece, and the second carrier plate 5 is used to carry a second workpiece; Two magnetic control positioning assemblies 6, which are arranged in the middle of the transmission device 1 and are used to position the first workpiece and the second workpiece respectively; A welding robot arm 3, which is located on one side of the transmission device 1; The visual inspection component 2 is mounted on the outside of the transmission device 1 and is used to obtain the welding surface shapes of the first workpiece and the second workpiece, thereby providing welding guidance for the welding robot arm 3, and to obtain the bottom surface shapes of the first workpiece and the second workpiece, thereby providing magnetic positioning guidance for the magnetic control positioning component 6.

[0021] The implementation includes the following steps: Step 1: The transport device 1 begins operation, transporting the first carrier plate 4 carrying the first workpiece. When the first carrier plate 4 enters the detection range of the visual inspection component 2, the visual inspection component 2 begins operation, obtains the bottom surface shape information of the first workpiece, and feeds this information back to the magnetic control positioning component 6. The welding surface shape information of the first workpiece is obtained and transmitted to the welding robot 3.

[0022] Step 2: The conveyor 1 continues to operate, transporting the second carrier 5 carrying the second workpiece. When the second carrier 5 enters the detection range of the visual inspection component 2, the visual inspection component 2 operates again, obtaining the bottom surface shape information of the second workpiece and feeding this information back to the magnetic control positioning component 6. The welding surface shape information of the second workpiece is obtained and transmitted to the welding robot 3.

[0023] Step 3: The magnetic control positioning component 6 accurately positions the workpieces (first workpiece, second workpiece) based on the bottom surface shape information of the workpieces to ensure that the positions of the workpieces are stable before welding.

[0024] Step 4: After the first workpiece and the second workpiece are positioned, the welding robot arm 3 plans the welding path and welding parameters according to the received welding surface shape information (the welding surface shape information of the first workpiece and the welding surface shape information of the second workpiece), and then performs welding operations on the first workpiece and the second workpiece according to the plan.

[0025] That is, the visual inspection component 2 starts working during the transfer of the first and second workpieces, and can obtain the bottom surface shape information of the workpieces in real time. This allows the magnetic control positioning component 6 to accurately position the workpieces based on the latest bottom surface shape information.

[0026] Furthermore, because the visual inspection component 2 can obtain the workpiece's weld surface shape information in advance and provide detailed welding guidance to the welding robot 3, the welding robot 3 can accurately plan the welding path and set parameters based on the actual workpiece's weld surface shape information. This helps ensure weld uniformity and consistent penetration during the welding process, reduces the occurrence of welding defects, and thus improves welding quality.

[0027] The entire welding process is highly automated, with each step, from workpiece transport and inspection to positioning and welding, working seamlessly together. The real-time operation of the visual inspection component 2 ensures timely acquisition and transmission of information, enabling the magnetic positioning component 6 and the welding robot 3 to complete their respective tasks quickly and accurately, improving production efficiency and reducing labor costs and the impact of human factors on welding quality.

[0028] In order to capture the bottom shapes of the first workpiece and the second workpiece, the first carrier plate 4 and the second carrier plate 5 are both made of transparent non-magnetic materials.

[0029] Specifically, the visual detection component 2 includes: A ring rail 21 is sleeved on the outside of the transmission device 1, and a bracket 22 is installed on the side of the ring rail 21; A moving assembly 23 movably disposed on the ring rail 21; A first vision sensor 24 and a second vision sensor 25 are mounted on the moving assembly 23 . The first vision sensor 24 is used to obtain the shapes of the welding surfaces of the first workpiece and the second workpiece. The second vision sensor 25 is used to obtain the shapes of the bottom surfaces of the first workpiece and the second workpiece.

[0030] The design of the circular rail 21 and the movable assembly 23 allows the first and second visual sensors 24 and 25 to flexibly move around the conveyor 1, enabling inspection of the first and second workpieces from various angles and positions. The first visual sensor 24 is dedicated to acquiring the weld surface shape information of the first and second workpieces, providing precise welding guidance for the welding robot 3. The second visual sensor 25 is specifically designed to acquire the bottom surface shape information of the first and second workpieces, providing accurate positioning information for the magnetic control positioning assembly 6.

[0031] In this embodiment, the magnetic control positioning component 6 includes: A mounting groove, in which a spiral track 61 is installed; Wheel grooves 62 are provided on the spiral track 61 at intervals, and a rotating wheel 63 is rotatably provided in the wheel grooves 62; a slide 64 slidably disposed on the spiral track 61 and driven by the rotating wheel 63; The magnetic attraction component is disposed on the slide 64 .

[0032] In addition, the magnetic attraction component includes: a lead screw 65 rotatably disposed in the slide 64 , wherein an extension line of the lead screw 65 coincides with the center of the spiral track 61 ; The nut seat 66 is slidably disposed on the slide seat 64 and is in transmission connection with the lead screw 65; The accommodating groove 69 is provided on the nut seat 66 and is used to accommodate the magnet control block 67 .

[0033] The maximum moving distance of the nut seat 66 on the slide 64 is greater than the pitch of the spiral track 61 .

[0034] The implementation includes the following steps: The wheel 63 on the spiral track 61 rotates. Since the wheel 63 contacts the slide 64, the wheel 63 drives the slide 64 to slide along the spiral track 61. Based on the workpiece bottom surface shape information fed back by the visual inspection component 2, the slide 64 is controlled to move on the spiral track 61 to a position that roughly corresponds to the position where the workpiece needs to be positioned.

[0035] When the slide 64 moves to the approximate position, the lead screw 65 rotates. The lead screw 65 is in transmission connection with the nut seat 66, and the rotation of the lead screw 65 drives the nut seat 66 to slide on the slide 64 limit position.

[0036] Based on more precise information about the bottom surface shape, the rotation angle and direction of lead screw 65 are controlled to move nut holder 66 to a precise position on slide 64. Because accommodating groove 69 is provided on nut holder 66 and magnetic control block 67 is accommodated within accommodating groove 69, movement of nut holder 66 drives movement of magnetic control block 67, thereby achieving precise adjustment of the position of magnetic control block 67, allowing it to accurately align with the desired location on the workpiece.

[0037] After the magnetic control block 67 reaches the accurate position, the magnetic attraction function is activated to accurately position the first workpiece or the second workpiece through magnetic force, ensuring that the position and posture of the workpiece on the transmission device 1 are stable.

[0038] Please refer to Figure 7 Center point 0 is the center point of spiral track 61, and positioning point A is the desired position of magnetic control block 67 in one example. During implementation, the magnetic control positioning assembly 6, through the coordination of spiral track 61 and rotating wheel 63, enables slide 64 to move over a wide range (to the line connecting center point 0 and positioning point A), achieving preliminary, approximate positioning. The transmission structure of lead screw 65 and nut 66 in the magnetic assembly further precisely adjusts the position of magnetic control block 67. Its maximum travel distance is greater than the pitch of spiral track 61, ensuring that magnetic control block 67 can move to any position within a certain range, ultimately reaching positioning point A. This achieves high-precision positioning of the workpiece, improving positioning accuracy and reliability.

[0039] In this embodiment, a magnet 68 is further embedded in the accommodating groove 69 , and the magnet 68 and the magnetic control block 67 after power is applied have opposite polarities and repel each other.

[0040] When the magnetic control block 67 reaches the correct position, power is applied to the magnetic control block 67. At this point, the magnets 68 in the receiving slot 69 and the powered magnetic control block 67 repel each other with opposite polarities. This mutual repulsion brings the magnetic control block 67 closer to the first or second workpiece, enhancing the magnetic attraction and thus improving the magnetic positioning effect.

[0041] Furthermore, a spring 610 for supporting the magnetic control block 67 is connected between the accommodating groove 69 and the magnetic control block 67. The spring 610 and the magnetic control block 67 are configured as follows: when the magnetic control block 67 is not powered, the magnetic control block 67 can overcome the supporting force of the spring 610 and be adsorbed on the magnet 68. At this time, the upper surface of the magnetic control block 67 is not higher than the upper surface of the accommodating groove 69.

[0042] That is, in this embodiment, when the magnetic control block 67 is not energized, it can be attracted to the magnet 68, with its upper surface no higher than the upper surface of the receiving groove 69. This prevents interference between the magnetic control block 67 and the first carrier 4 or the second carrier 5 during transport, ensuring smooth workpiece transport and avoiding problems such as the first carrier 4 or the second carrier 5 being stuck due to the protrusion of the magnetic control block 67. When energized, the mutual repulsive force between the opposite polarities of the magnetic control block 67 and the magnet 68, combined with the elasticity of the spring 610, brings the magnetic control block 67 closer to the workpiece, significantly enhancing the magnetic attraction and improving the magnetic positioning effect.

[0043] In this embodiment, the transmission device 1 includes: Two symmetrically arranged conveyor belts 11 are connected to each other via a synchronous shaft 12 to achieve synchronous transmission; A lifting cylinder 13 is located between the two conveyor belts 11, and a baffle 14 is fixed to the output end of the lifting cylinder 13; A pressure sensor is embedded in the baffle 14 .

[0044] During operation, the lifting cylinder 13 pushes the baffle 14 upward. Combined with a pressure sensor embedded in the baffle 14, it can accurately detect whether the first carrier plate 4 has reached the specified position. Of course, preferably, a lifting device is provided on one side of the lifting cylinder 13 to lift the first carrier plate 4, thereby preventing friction and wear between the first carrier plate 4 and the conveying device 1 when the second carrier plate 5 is conveyed.

[0045] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
