Technical Field
[0001] This invention belongs to the field of automotive welding technology, and in particular relates to an intelligent transfer device for multi-station automotive welding. Background Technology
[0002] In the process of automobile body manufacturing, welding is one of the core processes, which usually involves continuous operations at multiple stations, such as workpiece loading, positioning, welding and unloading. In order to achieve efficient production, it is necessary to automatically and accurately transfer workpieces between different stations. However, existing transfer devices still require manual intervention during the transfer process for workpiece placement, clamping activation, or release confirmation. This not only results in low production efficiency but also makes it difficult to adapt to the requirements of flexible, high-speed production. Furthermore, the transfer actions between each station are often controlled independently, leading to poor coordination, waiting times, and difficulty in achieving a seamless "placement-welding-removal" cycle, thus restricting the overall production line's cycle time. To address these issues, we provide a multi-station intelligent transfer device for automotive welding to solve the aforementioned problems. Summary of the Invention

[0014] Preferably, the rotating plate is provided with a conductive electromagnetic ring; the press interlock switch, the linkage on / off switch and the electromagnet form a series circuit with the locking power supply through the conductive electromagnetic ring.
[0015] The present invention has the following beneficial effects: 1. This invention automatically circulates and transfers workpieces between N workstations, achieving seamless connection of the welding process, reducing manual intervention, and improving production efficiency; 2.

[0018] 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. Example
[0019] Please see Figures 1 to 11 The present invention is an intelligent transfer device for multi-station automotive welding, comprising a base assembly 100, a support assembly 200, a rotating platform assembly 300, a transfer assembly 400, a positioning and clamping assembly 500, a linkage opening and closing assembly 600, and a pressing interlock assembly 700.
[0020] The base assembly 100 includes a mounting base 101 that is bolted to the ground, providing a stable mounting foundation for the entire device and supporting all the upper structures.
[0021] The support assembly 200 includes a support platform 201 located directly above the mounting base 101. A trapezoidal block 202 is fixed to the upper surface of the support platform 201 near the side. The support platform 201 is located above the mounting base 101 and supports the rotating platform assembly 300 and the transfer assembly 400. At the same time, the trapezoidal block 202 is used to push the linkage rod 602 during rotation to control the circuit on and off.
[0022] The rotating platform assembly 300 includes a rotating plate 301 positioned directly above the support platform 201, a conductive magnetic ring 302 mounted at the upper center of the rotating plate 301, and a drive motor 304 bolted to the upper end of the mounting base 101. The upper surface of the rotating plate 301 has three partitioned sections, corresponding to the "to be placed," "to be welded," and "to be picked up" workstations, respectively. The trapezoidal block 202 is located in the "to be picked up" section. The conductive magnetic ring 302 provides a power transmission channel for the rotating components, preventing cable entanglement. This embodiment uses three partitioned sections; in practical applications, there can be N partitioned sections, such as three, four, five… where N≥3.
[0023] The transfer assembly 400 includes three sets of angle plates 401 located at the upper partitioned sections of the rotating plate 301. A pressing cylinder 402 is fixed in the middle of the inner inclined surface of the angle plate 401. An electrode ring 407 is installed at the upper end of the plane where the angle plate 401 connects with the rotating plate 301. The electrode ring 407 cooperates with the electrode plate 603 to form a normally closed switch to control the circuit of the electromagnet 403. Two sets of electromagnets 403 located on both sides of the pressing cylinder 402 are fixed in the inner inclined surface of the angle plate 401. By controlling the on and off of the electromagnets 403, the movement of the clamping plate 501 is controlled.
[0024] The positioning and clamping assembly 500 includes two sets of clamping plates 501 located on the outer inclined surface of the angle plate 401, and the two sets of clamping plates 501 are located on both sides of the pressing cylinder 402. The end face of the clamping plate 501 is fixed with a metal rod 502 located on the inner inclined surface of the angle plate 401. The clamping plates 501 used clamp the workpiece from both sides to prevent it from shifting during the transfer process. At the same time, the metal rod 502 cooperates with the electromagnet 403 and is driven to move the clamping plate 501 by the magnetic force.
[0025] The linkage opening and closing assembly 600 includes a mounting bracket 601 installed on the inner plane of the angle plate 401 and a linkage rod 602 located inside the mounting bracket 601 and passing through the inner side of the electrode ring 407. The upper end of the linkage rod 602 is fixed with an electrode plate 603 that is electrically connected to the electrode ring 407. When the linkage rod 602 rotates, the lower end is pushed by the trapezoidal block 202, and the upper end drives the electrode plate 603 to move, which controls the on and off of the electromagnet 403. The electrode plate 603 is paired with the electrode ring 407. Under normal conditions, it contacts the electrode ring 407 to conduct the circuit. When it is pushed up, it separates and cuts off the circuit.
[0026] The press interlock assembly 700 includes a press rod 701 that slides inside the press cylinder 402, and an electrode post 702 and an electrode block 703 located inside the press cylinder 402 for controlling the on and off of the electromagnet 403. The electrode post 702 and the electrode block 703 are paired together to form a normally open switch triggered by pressure.
[0027] Specifically, according to Figure 3 and Figure 10 It is known that an insulating plate 604 is installed on the upper end face of the electrode plate 603. A spring 605 is fixed on the upper end face of the insulating plate 604 and abuts against the inner top surface of the mounting bracket 601. The plane of the angle plate 401 has a movable hole 406 that is aligned with the vertical position of the electrode ring 407. The upper end face of the rotating plate 301 has through holes 305 at the positions corresponding to the linkage rod 602. The lower end of the linkage rod 602 passes through the corresponding movable hole 406 and through hole 305. The spring 605 provides a downward elastic force to ensure that the electrode plate 603 and the electrode ring 407 maintain reliable normally closed contact when the linkage rod 602 is not in the lifting state.
[0028] according to Figure 7 , Figure 8 and Figure 11It is known that the end face of the pressing cylinder 402 is provided with a through hole 409 that communicates with its interior. The end of the electrode post 702 passes through the interior of the through hole 409. The electrode block 703 is installed at the end face of the pressing rod 701 inside the pressing cylinder 402. An insulating frame 704 is fixed to the end face of the pressing rod 701 inside the pressing cylinder 402. The end face of the insulating frame 704 opposite to the end face of the pressing rod 701 is fixed with a spring 705 that is connected to the inner end face of the pressing cylinder 402. The surface wall of the pressing cylinder 402 near the electromagnet 403 is provided with a strip-shaped opening 408. The cable on the surface of the electrode block 703 passes through the strip-shaped opening 408 and is electrically connected to the nearby electromagnet 403. When the car workpiece is removed, the spring 705 will push the pressing rod 701 and the electrode block 703 to reset, so that the electrode block 703 is separated from the electrode post 702, thereby disconnecting the power circuit of the electromagnet 403.
[0029] The annular protrusion at the upper end of the support platform 201 located within the trapezoidal block 202 is connected to the lower end of the rotating plate 301. The lower end face of the rotating plate 301 is bolted to a transmission plate 303 that passes through the inner ring of the support platform 201. The transmission plate 303 is connected to the drive motor 304. The transmission connection between the transmission plate 303 and the drive motor 304 can be a gear meshing transmission or a synchronous belt transmission.
[0030] Specifically, according to Figure 5 , Figure 6 ,and Figure 9 It is known that the inclined surface of the angle plate 401 is provided with a stroke opening 405 at the position corresponding to each clamping plate 501. The rectangular block fixed between the clamping plate 501 and the metal rod 502 slides in the stroke opening 405. Two sets of square plates 503 are fixed on the surface of the metal rod 502 and are connected to the inner inclined surface of the angle plate 401. A spring 505 is fixed on the end face of each set of square plates 503 near the pressing cylinder 402. A calibration plate 404 installed on the inner inclined surface of the angle plate 401 is provided at the position connected to the other end of the spring 505. A calibration rod 504 is fixed on the end face of each set of square plates 503 near the pressing cylinder 402 and passes through the hole on the spring 505 and the calibration plate 404. After the electromagnet 403 is de-energized, the spring 505 will push the clamping plate 501 to reset and release the automobile workpiece.
[0031] Furthermore, the mounting base 101 is used to fix and support the platform 201 by means of the rods installed at the upper end.
[0032] Furthermore, the cables of electrode post 702 and electrode ring 407 are electrically connected to the conductive ring 302. The switch composed of electrode post 702 and electrode block 703 and the switch composed of electrode ring 407 and electrode plate 603 are connected in series. The series circuit composed of the two sets of switches controls the on and off of electromagnet 403. The switch composed of electrode post 702 and electrode block 703 is a normally open switch, and the switch composed of electrode ring 407 and electrode plate 603 is a normally closed switch.
[0033] The operation process of this embodiment is as follows: First, three sets of transfer components 400 are respectively set in three partitioned sections on the upper end of the rotating plate 301. One partitioned section is the welding section, one partitioned section is the placement section, and the last partitioned section is the suction section. The drive motor 304 rotates in the order of the placement section, the welding section, and the suction section. An external robotic arm places the car workpiece onto the angle plate 401 in the placement area. The car workpiece pushes against the pressing rod 701. When the car workpiece comes into contact with the outer inclined surface of the angle plate 401, the pressing rod 701 controls the electrode block 703 to connect with the electrode post 702, thereby controlling the electromagnet 403 to be energized. The electromagnet 403 then attracts the metal rod 502, causing the two sets of clamping plates 501 to move relative to each other, thus clamping the car workpiece at the outer inclined surface of the angle plate 401 for subsequent welding processing. When welding is required, the drive motor 304 works and rotates the angle plate 401 of the placement area to the welding area. Then the drive motor 304 is de-energized and stops working. At this time, the external mechanical welding arm performs spot welding on the automotive workpiece. After the welding process is completed, the drive motor 304 starts working again and controls the car workpiece to rotate to the area to be picked up. During the rotation of the rotating plate 301, the linkage rod 602 gradually comes into contact with the inclined surface of the trapezoidal block 202. As a result, the trapezoidal block 202 pushes the linkage rod 602 to move upward. Then, the linkage rod 602 drives the electrode plate 603 to disengage from the electrode ring 407. As a result, the electromagnet 403 is de-energized. Then, the two sets of clamping plates 501 are pushed and reset by the spring 505. At this time, the mechanical suction arm can pick up and transfer the car workpiece.
[0034] It should be noted that after the transfer assembly 400 rotates to a certain position, the drive motor 304 within it will stop working so that the automotive workpiece on the angle plate 401 can be processed.
