Technical Field
[0001] This invention relates to the field of welding technology, specifically to an intelligent welding device for electromechanical equipment. Background Technology
[0002] In modern industrial manufacturing, electromechanical equipment occupies a crucial position due to its complex and diverse characteristics. This type of equipment covers a wide range, from precision instruments to large industrial machinery, and its manufacturing process requires high precision and technical expertise.
[0003] In the manufacturing process of electromechanical equipment, welding is a crucial step in connecting and fixing various components, and its quality directly affects 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 parts and support components. These workpieces often have different thicknesses and geometries, posing diverse challenges to the welding process.
[0004] To improve the versatility and flexibility of welding operations, many welding equipment are now equipped with magnetic positioning devices. However, existing magnetic positioning technologies mostly employ an array-distributed magnetic block design. While this fixed layout can achieve initial positioning of the workpiece to some extent, it often fails to achieve precise magnetic positioning when dealing with workpieces of complex shapes and varying sizes. The fixed position of the magnetic blocks limits its adaptability to different workpieces, potentially causing wobbling during welding, which in turn affects welding quality and efficiency.
[0005] Furthermore, traditional welding equipment has significant shortcomings in path planning. Currently, welding path planning often relies on manual operation, which not only requires operators to have rich 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
[0007] To address the aforementioned problems, the present invention provides the following technical solution: an intelligent welding device for electromechanical equipment, comprising: a transmission device for transmitting a first carrier plate and a second carrier plate, the first carrier plate for carrying a first workpiece and the second carrier plate for carrying a second workpiece; two magnetically controlled positioning components disposed in the middle of the transmission device for positioning the first workpiece and the second workpiece respectively; a welding robotic arm located on one side of the transmission device; and a vision inspection component sleeved on the outside of the transmission device for obtaining the welding surface shapes of the first and second workpieces to provide welding guidance for the welding robotic arm, and obtaining the bottom surface shapes of the first and second workpieces to provide magnetic positioning guidance for the magnetically controlled positioning components.
[0008] Preferably, both the first and second carrier plates are made of transparent, non-magnetic material.
[0009] Preferably, the vision inspection component includes: a ring rail, which is sleeved on the outside of the transmission device, and a bracket is installed on the side of the ring rail; a movable component, which is movably disposed on the ring rail; a first vision sensor and a second vision sensor mounted on the movable component, wherein the first vision sensor is used to obtain the welding surface shape of the first workpiece and the second workpiece, and the second vision sensor is used to obtain the bottom surface shape of the first workpiece and the second workpiece.
[0010] Preferably, the magnetic positioning component 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 disposed; a slide block slidably disposed on the spiral track and driven by the rotating wheel; and a magnetic attraction component disposed on the slide block.
[0011] Preferably, the magnetic attraction assembly includes: a lead screw, which is rotatably disposed in the slide, and the extension line of the lead screw coincides with the center of the helical track; a lead screw seat, which is slidably disposed on the slide and is connected to the lead screw in a transmission manner; and a receiving groove, which is formed on the lead screw seat for receiving the magnetic control block.
[0012] Preferably, a magnet is also embedded in the receiving groove, and the magnet and the magnetron block after being energized are mutually repulsive.
[0013] Preferably, a spring for supporting the magnetic control block is also connected between the receiving groove and the magnetic control block. The spring and the magnetic control block are configured such that when the magnetic control block is not energized, the magnetic control block can overcome the supporting force of the spring and be attracted to the magnet. At this time, the upper surface of the magnetic control block is not higher than the upper surface of the receiving groove.
[0014] Preferably, the maximum moving distance of the nut seat on the slide is greater than the pitch of the helical track.
[0015] Preferably, the transmission device includes: two symmetrically arranged transmission belts connected by a synchronous shaft for synchronous transmission; a lifting cylinder located between the two transmission belts, with a baffle fixed to the output end of the lifting cylinder; and a pressure sensor embedded in the baffle.
[0016] Compared with existing technologies, this invention provides an intelligent welding device for electromechanical equipment, which has the following beneficial effects: In this invention, the vision inspection component starts working during workpiece transport, acquiring real-time bottom surface shape information of the workpiece to help the magnetic positioning component accurately position itself, improving accuracy and reliability. Simultaneously, it acquires welding surface information of the workpiece in advance, guiding the welding robotic arm to precisely plan the path and set parameters, ensuring weld quality, reducing defects, and improving overall welding quality.
[0017] In this invention, the magnetic positioning component first uses a spiral track and a rotating wheel to allow the slide to move over a wide range to achieve approximate positioning; then, through the lead screw and lead screw seat transmission structure, the position of the magnetic control block is precisely adjusted, and its maximum movement distance exceeds the pitch of the spiral track, thereby improving the accuracy and reliability of positioning.

[0019] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.
[0020] Example: Please refer to Figures 1-7 In this embodiment of the invention, an intelligent welding device for electromechanical equipment is provided, comprising: 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 magnetically controlled positioning components 6 are disposed in the middle of the transmission device 1 and are used to position the first workpiece and the second workpiece respectively. Welding robotic arm 3 is located on one side of the transmission device 1; The visual inspection component 2, which is sleeved on the outside of the transmission device 1, is used to obtain the welding surface shape of the first workpiece and the second workpiece, thereby providing welding guidance for the welding robot arm 3, and to obtain the bottom surface shape of the first workpiece and the second workpiece, thereby providing magnetic positioning guidance for the magnetic positioning component 6.
[0021] The implementation includes the following steps: Step 1: The transmission device 1 starts operating and transmits the first carrier plate 4 carrying the first workpiece. When the first carrier plate 4 enters the detection range of the vision inspection component 2, the vision inspection component 2 starts working, acquires the bottom surface shape information of the first workpiece, and feeds this information back to the magnetic positioning component 6, acquires the welding surface shape information of the first workpiece, and transmits this information to the welding robotic arm 3.
[0022] Step 2: The transmission device 1 continues to operate, transmitting the second carrier plate 5 carrying the second workpiece. When the second carrier plate 5 enters the detection range of the vision inspection component 2, the vision inspection component 2 works again, acquiring the bottom surface shape information of the second workpiece and feeding this information back to the magnetic positioning component 6, acquiring the welding surface shape information of the second workpiece, and transmitting this information to the welding robotic arm 3.
[0023] Step 3: The magnetic positioning component 6 accurately positions the workpieces (first workpiece and second workpiece) based on the bottom surface shape information to ensure the stability of the workpieces before welding.
[0024] Step 4: After the first and second workpieces are positioned, the welding robot arm 3 plans the welding path and welding parameters based on the received welding surface shape information (welding surface shape information of the first workpiece and welding surface shape information of the second workpiece), and then performs welding operations on the first and second workpieces according to the plan.
[0025] In other words, the vision inspection component 2 begins operating during the transfer of the first and second workpieces, enabling it to acquire the bottom surface shape information of the workpieces in real time. This allows the magnetic positioning component 6 to perform precise positioning based on the latest bottom surface shape information of the workpieces.
[0026] Furthermore, since the vision inspection component 2 can acquire the welding surface shape information of the workpiece in advance and provide detailed welding guidance for the welding robotic arm 3, the welding robotic arm 3 can perform precise welding path planning and parameter settings based on the actual welding surface shape information of the workpiece. This helps to ensure the uniformity of the weld and the consistency of the penetration depth during the welding process, reduce the generation of welding defects, and thus improve the welding quality.
[0027] The entire welding process is highly automated, with each step—from workpiece transfer and inspection to positioning and welding—working in close coordination. The real-time operation of the vision inspection component 2 ensures timely information acquisition and transmission, enabling the magnetic positioning component 6 and the welding robotic arm 3 to complete their respective tasks quickly and accurately. This improves production efficiency and reduces labor costs and the impact of human factors on welding quality.
[0028] In order to capture the bottom shape of the first and second workpieces, both the first carrier plate 4 and the second carrier plate 5 are made of transparent, non-magnetic material.
[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. The movable component 23 is movably disposed on the ring track 21; A first vision sensor 24 and a second vision sensor 25 are mounted on the moving component 23. The first vision sensor 24 is used to obtain the welding surface shape of the first workpiece and the second workpiece, and the second vision sensor 25 is used to obtain the bottom surface shape of the first workpiece and the second workpiece.
[0030] The design of the ring track 21 and the moving component 23 allows the first vision sensor 24 and the second vision sensor 25 to move flexibly around the transmission device 1, enabling them to detect the first and second workpieces from different angles and positions. The first vision sensor 24 focuses on acquiring the welding surface shape information of the first and second workpieces, providing precise welding guidance for the welding robot arm 3; the second vision sensor 25 is specifically used to acquire the bottom surface shape information of the first and second workpieces, providing accurate positioning basis for the magnetic positioning component 6.
[0031] In this embodiment, the magnetic positioning component 6 includes: The mounting slot has a spiral track 61 installed inside it; Wheel grooves 62 are spaced apart on the spiral track 61, and a rotating wheel 63 is rotatably disposed in the wheel grooves 62; A slide block 64 is slidably disposed on the spiral track 61 and driven by the wheel 63; A magnetic suction assembly is disposed on the slide 64.
[0032] In addition, the magnetic attraction component includes: A lead screw 65 is rotatably mounted in the slide block 64, and the extension line of the lead screw 65 coincides with the center of the spiral track 61; The lead screw seat 66 is slidably mounted on the slide block 64 and is connected to the lead screw 65 for transmission. A receiving groove 69 is provided on the wire nut seat 66 for receiving the magnetron block 67.
[0033] The maximum moving distance of the nut 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. As the wheel 63 contacts the slide block 64, the wheel 63 drives the slide block 64 to slide along the spiral track 61. Based on the workpiece bottom surface shape information fed back by the vision inspection component 2, the movement position of the slide block 64 on the spiral track 61 is controlled so that the slide block 64 moves to a position that roughly corresponds to the position that the workpiece needs to be positioned.
[0035] After the slide 64 moves to its approximate position, the lead screw 65 rotates. The lead screw 65 is connected to the lead screw nut 66, and the rotation of the lead screw 65 causes the lead screw nut 66 to slide at the upper limit of the slide 64.
[0036] Based on more precise bottom surface shape information, the rotation angle and direction of the lead screw 65 are controlled, causing the lead screw nut 66 to move to a precise position on the slide 64. Since the receiving groove 69 is formed on the lead screw nut 66, the magnetic control block 67 is housed in the receiving groove 69. The movement of the lead screw nut 66 drives the magnetic control block 67 to move, thereby achieving precise adjustment of the position of the magnetic control block 67, enabling the magnetic control block 67 to accurately align with the part of the workpiece that needs to be positioned.
[0037] After the magnetic control block 67 reaches the accurate position, the magnetic attraction function is activated to accurately position the first or second workpiece using magnetic force, ensuring the stability of the workpiece's position and posture on the transmission device 1.
[0038] Please refer to Figure 7 Center point 0 is the center point of the spiral track 61, and positioning point A is the position that the magnetic control block 67 needs to reach in one example. During implementation, the magnetic positioning component 6, through the cooperation of the spiral track 61 and the rotating wheel 63, enables the slide block 64 to move within a large range (to the line connecting center point 0 and positioning point A), achieving preliminary approximate positioning. The transmission structure of the lead screw 65 and lead screw nut 66 in the magnetic suction component can further precisely adjust the position of the magnetic control block 67. Its maximum movement distance is greater than the pitch of the spiral track 61, ensuring that the magnetic control block 67 can move to any position within a certain range, thereby moving to positioning point A. This achieves high-precision positioning of the workpiece and improves the accuracy and reliability of positioning.
[0039] In this embodiment, a magnet 68 is also embedded in the receiving groove 69, and the magnet 68 and the magnetron block 67 after being energized are mutually repulsive due to their opposite polarity.
[0040] Once the magnetoresistive block 67 reaches the accurate position, it is energized. At this time, the magnet 68 in the receiving groove 69 and the energized magnetoresistive block 67 are mutually repulsive due to their opposite polarity. This repulsive force makes the magnetoresistive block 67 closer to the first or second workpiece, and the magnetic attraction is enhanced, thereby improving the magnetic positioning effect.
[0041] Furthermore, a spring 610 for supporting the magnetic control block 67 is also connected between the receiving groove 69 and the magnetic control block 67. The spring 610 and the magnetic control block 67 are configured such that when the magnetic control block 67 is not energized, the magnetic control block 67 can overcome the supporting force of the spring 610 and be attracted to the magnet 68. At this time, the upper surface of the magnetic control block 67 is not higher than the upper surface of the receiving groove 69.
[0042] In other words, in this embodiment, when the magnetron 67 is not energized, it can be attracted to the magnet 68, and its upper surface is not higher than the upper surface of the receiving groove 69. This ensures that the magnetron 67 will not interfere with the first carrier plate 4 or the second carrier plate 5 during transport, guaranteeing smooth workpiece transport and avoiding problems such as jamming of the first carrier plate 4 or the second carrier plate 5 due to the protrusion of the magnetron 67. When energized, the repulsive force between the magnetron 67 and the magnet 68, along with the elasticity of the spring 610, brings the magnetron 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 transmission belts 11 are connected by 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 implementation, the lifting cylinder 13 pushes the baffle 14 upward, and combined with the pressure sensor embedded in the baffle 14, it can accurately detect whether the first carrier plate 4 has reached the designated position. Of course, more preferably, a lifting device is provided on one side of the lifting cylinder 13 to lift the first carrier plate 4, so as to prevent the first carrier plate 4 from constantly rubbing and wearing against the transmission device 1 when the second carrier plate 5 is being transported.
[0045] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
