Abstract
Description
Technical Field
[0001] This invention relates to the field of positioning equipment technology, specifically to an automatic welding positioning device for low-voltage electrical components. Background Technology
[0002] Low-voltage electrical components refer to basic electrical parts that operate in AC circuits below 1200V and DC circuits below 1500V, enabling circuit control, regulation, conversion, detection, and protection. They are key components in complete sets of electrical equipment. Examples include circuit breakers, contactors, and push-button switches, which control circuit on / off; fuses, thermal relays, and residual current devices, which protect circuits and equipment; intermediate relays and time relays, which handle signal processing and timing control; and current transformers, voltage transformers, and proximity switches, which collect circuit operating parameters. From applications to everything from small household appliances to large industrial equipment and building electrical systems, low-voltage electrical components are indispensable for ensuring the rational distribution of electrical energy and stable equipment operation. Automatic welding and positioning equipment for low-voltage electrical components is a specialized device tailored for welding scenarios, integrating mechanical positioning, automated control, and precision welding functions. Its core function is to ensure that low-voltage electrical components are precisely positioned during welding, guaranteeing welding quality and efficiency.
[0003] Currently, rectangular power strips are commonly used low-voltage electrical components. During the welding process, workers often fix a single power strip on a fixture and then transport it to the welding machine via a conveyor. Since power strip components often have beveled surfaces, when it is necessary to rotate the power strip to a certain angle before welding, the fixture is precisely rotated to a certain angle by the control equipment before welding the next hole. After all the welding parts on one power strip are completed, the next power strip is welded. The positioning equipment usually only has one clamping component, resulting in a long welding process and a long welding time for a single power strip, which reduces the welding efficiency.
[0004] Therefore, we propose an automatic welding and positioning device for low-voltage electrical components to solve the problems mentioned above. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. When welding rectangular low-voltage electrical component power strips, multiple power strips are first fixed between multiple sets of tightening blocks. They are then rotated to the position of the welding equipment body adjacent to the controller for forward welding. Next, the power strips are rotated along the connecting rod and transported to the position of the next welding equipment body for inclined welding. Finally, the power strips are rotated along the inclined plane by forward and reverse motors and welded. This achieves automatic welding of multiple sides of the power strip components, improving work efficiency while saving resources. It solves the problem in existing technologies where rectangular power strip component positioning equipment often has only one clamping structure, resulting in long welding times and reduced welding efficiency.
[0018] 2. After the beveled surface of the power strip is welded, the connecting rod is first driven to rotate and reset under the action of the coil spring. Then, the screw and the clamping block are separated, so that the clamping block is reset. The servo motor is started, which drives the bidirectional lead screw to rotate in the opposite direction, thereby separating the two tightening blocks and removing the power strip. At the same time, the two tightening blocks are fully reset, and the reset two tightening blocks can be rotated to the top of the conveying device to clamp the next power strip.
[0019] 3. When the required rotation angle of the power strip component to be welded changes, if the required rotation angle decreases, the sealing cover can be rotated towards the outer surface of the multiple protrusions, reducing the exposed protrusions and thus lowering the rotation angle of the first toothed ring, thereby reducing the rotation angle of the power strip component. If the required rotation angle of the power strip component increases, the power motor can be started in reverse and the friction roller can be rotated in reverse. Through the action of the self-rotating component, the rotation angle of the power strip component can be intelligently adjusted, further improving the practicality of the automatic welding and positioning equipment for low-voltage electrical components.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Please see Figure 1-12The present invention provides a technical solution: an automatic welding and positioning device for low-voltage electrical components, wherein one end of multiple rotor shafts 616 is coupled to a driven gear disk 617, the outer surface of multiple bidirectional extension rods 606 is fixed with a support frame 618, the outer surface of multiple drive rods 619 is fixedly sleeved with an electric drive shaft 620, the outer surface of multiple mounting brackets 621 is fixedly mounted with a servo motor 622 by bolts, the output end of multiple servo motors 622 is fixedly connected with a bidirectional lead screw 623, each pair of multiple tightening blocks 624 is a group, and a cylinder 625 is set between the outer surfaces of each group of tightening blocks 624 through an auxiliary frame, one end of multiple cylinders 625 is fixedly mounted with a push plate 626, the drive assembly 5 includes a base 501, the bottom of the base 501 is fixedly connected to the top of the base plate 1, and a rotating shaft 502 is rotatably connected inside the base 501. The top of the 2 extends to the outside of the base 501. The outer surface of the rotating shaft 502 is fixedly fitted with a second toothed ring 503 near the bottom. The top of the base 501 is fitted with a stepper motor 504 via an auxiliary frame. The output end of the stepper motor 504 is fixedly connected to a drive shaft 505. The outer surface of the drive shaft 505 is fixedly fitted with a gear 506. The outer surface of the gear 506 meshes with the outer surface of the second toothed ring 503. The bottom end of the drive shaft 505 extends sequentially to the inside of the auxiliary frame and to the inner wall. One end of multiple connecting rods 601 is movably embedded inside the rotating shaft 502. Multiple mounting boxes 602 are fixedly coupled inside the rotating shaft 502. The top of the base plate 1 is fitted with a conveying device 2 near one side edge. The outer surfaces of the two welding equipment bodies 4 are fixedly connected to the top of the base plate 1 by screws. The top of the base plate 1 is fitted with a controller 3 near the rear surface.
[0036] In this embodiment, when it is necessary to solder a rectangular low-voltage electrical component: a power strip, the power strip is first conveyed by the conveying device 2 to the outer surface between the two corresponding tightening blocks 624. The working principle of the conveying device 2 is a mature existing technology and will not be described in detail here. Figure 1As shown, during the power strip conveying process, it is limited by two horizontally arranged bar rods at the top of the conveying device 2. The shortest horizontal distance between the two bar rods corresponds to the width of the power strip and the distance between the two tightening blocks 624. Driven by the conveying device 2, the power strip moves between the outer surfaces of the two tightening blocks 624 and contacts the outer surface of the push plate 626 under the action of inertia. At this time, the controller 3 can first start the cylinder 625 corresponding to the power strip to push the push plate 626 forward a certain distance, thereby determining the specific position of the power strip in the fixture. Then, the controller 3 can start the servo motor 622 to drive the bidirectional lead screw 623 to rotate, thereby driving the two tightening blocks 624 to move towards each other, thereby clamping the power strip. Then, the controller 3 can start the stepper motor 504 to drive the drive shaft 505 to rotate clockwise, thereby driving the gear 506 to rotate, and then driving the second gear ring 50 The controller 3 rotates, thereby driving the rotating shaft 502 to rotate. The rotation of the rotating shaft 502 drives multiple connecting rods 601 to rotate, which in turn drives a set of clamping blocks 624 holding the power strip to rotate towards the welding equipment body 4 adjacent to the controller 3, until the part of the power strip that needs to be welded moves to the position facing the welding head in the welding equipment body 4. Then the stepper motor 504 can be turned off and the welding equipment body 4 can be started to weld the front of the power strip. At this time, another set of clamping blocks 624 just rotates to the top of the conveyor device 2, and the two clamping blocks 624 correspond to the two strip rods. The above action can be repeated to place the next power strip on the conveyor belt of the conveyor device 2 and transport it between the outer surfaces of the two facing clamping blocks 624. Through the cooperation of the positioning component 6 and the drive component 5, the low-voltage electrical component automatic welding positioning equipment can continuously clamp the power strip for continuous welding by rotating clamping, thereby improving welding efficiency.
[0037] like Figures 1-3As shown, an automatic welding and positioning device for low-voltage electrical components includes a base plate 1 and two welding device bodies 4 for automatically welding electrical components. A drive assembly 5 is disposed on the top of the base plate 1 near one edge. Multiple positioning assemblies 6 for fixing the low-voltage electrical components are disposed on the top of the drive assembly 5. Each positioning assembly 6 includes a connecting rod 601. A first toothed ring 605 for driving rotation is fixedly sleeved on the outer surface of each connecting rod 601 near the center. Two clamping and fixing devices are disposed at one end of each connecting rod 601. The clamping blocks 624 are arranged in pairs, with each pair of clamping blocks 624 forming a group. Each group of clamping blocks 624 has a mounting bracket 621 slidably connected between its outer surface. Each mounting bracket 621 has an electric drive shaft 620 fixedly mounted on its rear surface. Each electric drive shaft 620 has a drive rod 619 rotatably connected to its inner wall for supporting the rotation of the low-voltage electrical components. A self-rotating component 7 is provided between the bottoms of the multiple positioning components 6 for driving the low-voltage electrical components to rotate at another angle. The self-rotating component 7 includes a fixing ring 702, and the inner wall of the fixing ring 702 is provided with multiple protrusions 709.
[0038] In this embodiment, after the wiring board corresponding to the welding equipment body 4 adjacent to the controller 3 is welded, a set of tightening blocks 624 at the top of the conveying device 2 is just clamped. The controller 3 can then restart the stepper motor 504, driving the rotating shaft 502 to continue rotating. Simultaneously, the wiring board corresponding to the welding equipment body 4 is rotated to the position of the next welding equipment body 4, and the inclined surface of this wiring board is welded. To ensure that the inclined surface of the wiring board is aligned with the welding head position in the next welding equipment body 4, during the rotation and conveying of the wiring board, the first tooth corresponding to this wiring board is... The ring 605 rotates along the socket plate. When the outer surface of the first toothed ring 605 contacts the outer surface of the multiple protrusions 709, it is pushed by the multiple protrusions 709, causing the first toothed ring 605 to rotate, thereby causing the connecting rod 601 connected to it to rotate, which in turn causes the corresponding coil spring 603 to tighten, and then the mounting bracket 621 to rotate, thereby causing the two tightening blocks 624 to rotate, and finally causing the socket plate to rotate. When the socket plate moves to the position corresponding to the next welding equipment body 4, the socket plate is rotated to the required angle, and the next welding equipment body 4 can be started to weld the inclined surface of the socket plate.

Support frames 618 are fixed to the outer surface of extension rods 606. Electric drive shafts 620 are fixedly sleeved on the outer surface of multiple drive rods 619. Servo motors 622 are fixedly mounted on the outer surface of multiple mounting brackets 621 by bolts. Bidirectional lead screws 623 are fixedly connected to the output ends of multiple servo motors 622. Each pair of adjacent tightening blocks 624 forms a group. Cylinders 625 are set between the outer surfaces of each group of tightening blocks 624 through auxiliary frames. Push plates 626 are fixedly mounted on one end of multiple cylinders 625. Drive rings 8 are movably sleeved between the outer surfaces of multiple connecting rods 601. Both ends of multiple connecting rods 601 movably extend to the opposite sides of the drive ring 8. One end of multiple connecting rods 604 is fixedly connected to one end of each of the multiple connecting rods 601.One end of each of the multiple multi-stage electric telescopic rods 608 is fixedly connected to the outer surface of multiple positioning plates 607. Multiple telescopic tubes 613 are grouped in pairs, and one end of each group of telescopic tubes 613 is fixedly connected to the outer surface of multiple drive rods 619.

The opposite outer surfaces of multiple auxiliary frames are fixedly connected to the outer surface of each group of tightening blocks 624.
[0040] In this embodiment, when welding is required on other surfaces of the inclined plane, firstly, the two multi-stage electric telescopic rods 608 corresponding to the power strip are activated to shorten them, causing the two screws 611 to be inserted into the interiors of the two corresponding locking blocks 612. Simultaneously, the forward and reverse motors 615 are activated, causing the rotor shaft 616 to rotate, which in turn causes the driven gear plate 617 to rotate. The driven gear plate 617 causes the driving gear plate 610 to rotate, which in turn causes the screws 611 to rotate until one end of the screw 611 is fully inserted into the deepest part of the corresponding locking block 612, thus achieving the connection between the two screws 611 and the two locking blocks 612. Then, the two multi-stage electric telescopic rods 608 can be activated again to extend them, causing the two positioning plates 607 to move away from each other, which in turn causes the two screws 611 to move away from each other, thereby causing the two locking blocks 612 to move to the outside of the support frame 618 under the action of tension, thus enabling the two When spring 614 is stretched by the tension, the forward and reverse motor 615 can be restarted, driving screw 611 to rotate, which in turn drives two clamping blocks 612 to rotate, causing two telescopic tubes 613 to rotate, which in turn drives drive rod 619 to rotate. The rotation of drive rod 619 drives electric drive shaft 620 to rotate, which in turn drives mounting bracket 621 to rotate, which in turn drives two tightening blocks 624 to rotate, thus driving the power strip to rotate until the inclined surface of the power strip rotates to the required angle. Then, the inclined surface of the power strip can be welded by the welding equipment body 4, which is away from controller 3. Through the combination of positioning component 6 and self-rotating component 7, automatic welding of the inclined surface of the power strip is realized. Moreover, during the initial rotation of the power strip, no additional drive equipment is needed to drive its rotation, which improves work efficiency and saves resources. This solves the problem that existing rectangular power strip positioning equipment often has only one clamping structure, resulting in long clamping and welding times and reduced welding efficiency.

Two multi-stage electric telescopic rods 608 are provided on the inner walls of each of the multiple bidirectional extension rods 606. A positioning plate 607 is movably embedded near one edge of the inner wall of each of the multiple positioning plates 607. A limiting rod 609 is provided, and an active gear plate 610 is fixedly sleeved on the outer surface of multiple limiting rods 609. A screw 611 is fixed to one end of each of the multiple limiting rods 609. A locking block 612 is threadedly connected to the outer surface of each of the multiple screws 611. A telescopic tube 613 is fixedly installed on the outer surface of each of the multiple locking blocks 612. A spring 614 is provided on the outer surface of each of the multiple telescopic tubes 613. A forward and reverse motor 615 is provided on the inner wall of multiple positioning plates 607 near the other edge. A rotor shaft 616 is fixedly connected to the output end of each of the multiple forward and reverse motors 615.
[0042] In this embodiment, after the beveled surface of the power strip is welded, the power strip can be rotated again by the stepper motor 504. At this time, the first toothed ring 605 corresponding to the power strip is separated from the multiple protrusions 709, so that the connecting rod 601 rotates back to its original position under the action of the corresponding coil spring 603. Then, the forward and reverse motors 615 are started again to drive the two locking blocks 612 to rotate back to their original positions in the opposite direction. When the two locking blocks 612 are reset, they correspond to the two slots in the support frame 618 used to limit the locking blocks 612. Then, the two multi-stage electric telescopic rods 608 can be started again to shorten them, causing the two locking blocks 612 to be inserted into the support frame 618 respectively. Internally, the locking block 612 is limited, and then the forward and reverse motors 615 can be started in reverse. At the same time, the two multi-stage electric telescopic rods 608 are slowly extended. The shortening distance of the two multi-stage electric telescopic rods 608 matches the length of the screw 611, thereby separating the two screws 611 from the two locking blocks 612. Then, the servo motor 622 is started, driving the bidirectional lead screw 623 to rotate in the opposite direction, thereby separating the two tightening blocks 624 and removing the power strip. At the same time, the two tightening blocks 624 are completely reset, and the reset two tightening blocks 624 can be rotated to the top of the conveying device 2 to clamp the next power strip.
[0043] like Figures 1-2 and Figures 9-12 As shown, the self-rotating assembly 7 also includes four vertical rods 701. A sealing cover 703 is slidably connected to the inner wall of the fixing ring 702. A rubber ring 704 is coupled to the inner wall of the sealing cover 703. A connecting ring 705 is fixed between the outer surfaces of two vertical rods 701. A positioning frame 706 is fixedly installed on the top of the connecting ring 705. A power motor 707 is installed on the inner top surface of the positioning frame 706. A friction roller 708 is fixedly connected to the output end of the power motor 707 through a transmission shaft. Multiple elastic elements 710 are coupled to the inner bottom surface of the fixing ring 702. The top ends of the four vertical rods 701 are fixedly connected to the bottom of the fixing ring 702. The outer surface of the friction roller 708 is in contact with the outer surface of the rubber ring 704. The top ends of the multiple elastic elements 710 are fixedly connected to the bottom of the multiple protrusions 709 respectively.
[0044] In this embodiment, when the required rotation angle of the socket component to be soldered changes, and the required rotation angle decreases, the controller 3 can start the power motor 707 to drive the friction roller 708 to rotate. This, in turn, drives the rubber ring 704 to rotate under the action of friction, thereby causing the sealing cover 703 to rotate along the inside of the fixing ring 702. This pushes the sealing cover 703 towards the outer surface of the multiple protrusions 709, such as... Figure 12As shown, since both sides of the protrusion 709 are inclined, under the pressure of the sealing cover 703, the protrusion 709 will be moved into the interior of the fixing ring 702 by the elastic action of the elastic element 710, thereby reducing the exposed protrusion 709 and thus reducing the rotation angle of the first toothed ring 605, which in turn reduces the rotation angle of the power strip component. When the required rotation angle of the power strip component increases, the power motor 707 is started in reverse and the friction roller 708 is rotated in reverse. Through the action of the self-rotating component 7, the rotation angle of the power strip component can be intelligently adjusted, further improving the practicality of the automatic welding and positioning equipment for low-voltage electrical components.
[0045] The usage and working principle of this device are as follows: When it is necessary to solder rectangular power strip components, the power strip is first conveyed by the conveying device 2 to the outer surface between the two corresponding tightening blocks 624, such as... Figure 1As shown, during the power strip's transport, it is limited by two horizontally positioned strip rods at the top of the transport device 2. The shortest horizontal distance between the two strip rods corresponds to the width of the power strip and the distance between the two tightening blocks 624. Driven by the transport device 2, the power strip moves between the outer surfaces of the two tightening blocks 624 and contacts the outer surface of the push plate 626 under inertia. At this point, the controller 3 first activates the cylinder 625 corresponding to the power strip, pushing the push plate 626 forward a certain distance to determine the power strip's specific position in the fixture. Then, the controller 3 activates the servo motor 622, driving the bidirectional lead screw 623 to rotate, which in turn drives the two tightening blocks 624 to move towards each other. The power strip is clamped, and then the stepper motor 504 is started by the controller 3, driving the drive shaft 505 to rotate clockwise, which in turn drives the gear 506 to rotate, which in turn drives the second gear ring 503 to rotate, thereby driving the rotating shaft 502 to rotate. The rotation of the rotating shaft 502 drives multiple connecting rods 601 to rotate, which in turn drives a set of clamping blocks 624 holding the power strip to rotate towards the welding equipment body 4 adjacent to the controller 3, until the part of the power strip that needs to be welded moves to the position directly opposite the welding head in the welding equipment body 4. Then the stepper motor 504 can be turned off. The welding equipment body 4 uses a high-energy-density laser beam to focus on the welding part of the power strip, instantly melting the metal and solidifying it to form a solder joint. The laser spot diameter can be less than 0.1mm, achieving... Micrometer-level positioning: Before welding, an industrial camera identifies the terminal position, guiding the laser head to align with the solder joint. A pulsed laser irradiates the solder joint, instantly vaporizing and melting the metal. After the laser withdraws, the molten pool rapidly cools to form a strong solder joint, achieving the welding of the power strip components. The welding equipment body 4 is then activated to weld the front side of the power strip. At this time, another set of tightening blocks 624 rotates to the top of the conveyor device 2, with the two tightening blocks 624 corresponding to the two strip rods. The above actions can be repeated to place the next power strip onto the conveyor belt of the conveyor device 2 and transport it between the outer surfaces of the two opposing tightening blocks 624. When the power strip corresponding to the welding equipment body 4 adjacent to the controller 3 is welded, the top of the conveyor device 2... Once a set of tightening blocks 624 has been clamped, the stepper motor 504 can be restarted via the controller 3 to drive the rotating shaft 502 to continue rotating. Simultaneously, the plug plate corresponding to the welding equipment body 4 is rotated to the next welding equipment body 4 position for welding on its inclined surface. To align the inclined surface of the plug plate with the welding head position in the next welding equipment body 4, during the rotation and transport of the plug plate, the first toothed ring 605 corresponding to the plug plate rotates along the plug plate. When the outer surface of the first toothed ring 605 contacts the outer surface of the multiple protrusions 709, it is pushed by the protrusions 709, causing the first toothed ring 605 to rotate, thereby driving the connected rod 601 to rotate.This causes the corresponding coil spring 603 to tighten, which in turn rotates the mounting bracket 621, causing the two tightening blocks 624 to rotate, ultimately driving the socket plate to rotate. When the socket plate moves to the position corresponding to the next welding equipment body 4, the socket plate rotates to the required angle, allowing the next welding equipment body 4 to start welding the inclined surface of the socket plate. When welding other surfaces in the inclined surface is required, firstly, the two multi-stage electric telescopic rods 608 corresponding to the socket plate are activated to shorten them, causing the two screws 611 to be inserted into the two corresponding locking blocks 612. At the same time, the forward and reverse motors 615 are activated, driving the rotor shaft 616 to rotate, which in turn drives the driven gear plate 617 to rotate. The driven gear plate 617 drives the driving gear... The disc 610 rotates, which in turn drives the screw 611 to rotate until one end of the screw 611 is fully inserted into the deepest part of its corresponding locking block 612, thus connecting the two screws 611 with the two locking blocks 612. Then, the two multi-stage electric telescopic rods 608 can be activated again to extend them, causing the two positioning plates 607 to move away from each other, which in turn causes the two screws 611 to move away from each other. This causes the two locking blocks 612 to move to the outside of the support frame 618 under the action of tension, which in turn causes the two springs 614 to be stretched. At this point, the forward and reverse motors 615 can be activated again to drive the screws 611 to rotate, which in turn drives the two locking blocks 612 to rotate, thus causing the two telescopic tubes 613 to rotate. The movement of the drive rod 619 causes the drive shaft 620 to rotate, which in turn causes the mounting bracket 621 to rotate, which in turn causes the two tightening blocks 624 to rotate, thus causing the socket plate to rotate until the inclined surface of the socket plate rotates to the required angle. Then, the inclined surface of the socket plate can be welded by the welding equipment body 4 away from the controller 3. After the inclined surface of the socket plate is welded, the socket plate can be rotated again by the stepper motor 504. At this time, the first toothed ring 605 corresponding to the socket plate is separated from the multiple protrusions 709, so that the connecting rod 601 rotates back to its original position under the action of its corresponding coil spring 603. Then, the forward and reverse motor 615 is started again to drive the two locking blocks 612 to rotate back to their original position in the opposite direction. When 612 resets, it corresponds precisely to the two slots in the support frame 618 used to limit the locking blocks 612. This allows the two multi-stage electric telescopic rods 608 to be activated again, shortening them and causing the two locking blocks 612 to insert into the support frame 618, limiting their movement. Then, the forward and reverse motors 615 are activated in reverse, simultaneously extending the two multi-stage electric telescopic rods 608 slowly. The shortening distance of the two multi-stage electric telescopic rods 608 matches the length of the screw 611, causing the two screws 611 to separate from the two locking blocks 612. This activates the servo motor 622, driving the bidirectional lead screw 623 to rotate in the reverse direction, causing the two tightening blocks 624 to separate, allowing the power strip to be removed and the two tightening blocks 624 to fully reset.The two tightening blocks 624, after being reset, can be rotated back to the top of the conveying device 2 to clamp the next power strip. When the required rotation angle of the power strip component to be soldered changes, and the required rotation angle decreases, the controller 3 can start the power motor 707, driving the friction roller 708 to rotate. This, in turn, drives the rubber ring 704 to rotate under the action of friction, thereby causing the sealing cover 703 to rotate along the inside of the fixing ring 702. This pushes the sealing cover 703 towards the outer surface of the multiple protrusions 709, such as... Figure 12 As shown, since both sides of the protrusion 709 are inclined, under the pressure of the sealing cover 703, the protrusion 709 will be moved into the interior of the fixing ring 702 by the elastic action of the elastic member 710, thereby reducing the exposed protrusion 709, thereby reducing the rotation angle of the first toothed ring 605, and thus reducing the rotation angle of the power strip component. When the required rotation angle of the power strip component increases, the power motor 707 is started in reverse and the friction roller 708 is rotated in reverse.
