Description

Technical Field

[0001] This utility model relates to the field of circuit board welding technology, and specifically to a welding device with a fixture mounted on top. Background Technology

[0002] Circuit board soldering is the process of connecting electronic components to a circuit board using molten solder (usually a tin alloy). This process requires not only stable and reliable electrical connections, but also mechanical strength to withstand external forces such as vibration and impact in the operating environment.

[0003] Traditional semi-automatic soldering machines can automatically deliver solder wire and move circuit boards, but require manual handling of the wire to the soldering position. This soldering process requires the arm to repeatedly perform a single mechanical movement, which not only increases the workload of the arm, but is also cumbersome, inefficient, and impractical.

[0028] Reference Figure 2As shown in Figure 3, the longitudinal movement module includes a U-shaped base frame 301 fixedly connected to the upper surface of the worktable 1. A threaded rod 302 is rotatably connected to the upper part of the U-shaped base frame 301. A threaded seat 303 is threadedly connected to the threaded rod 302. A servo motor 304 for driving the threaded rod 302 to rotate is fixedly installed at the rear end of the U-shaped base frame 301. The connecting platform 3 is fixedly connected to the upper surface of the threaded seat 303. The bottom surface of the threaded seat 303 is clearance-fitted with the bottom surface of the U-shaped base frame 301. By driving the threaded rod 302 to rotate through the servo motor 304, the threaded seat 303 connected to it can be driven to move back and forth in the U-shaped base frame 301. Through the connection of the connecting platform 3, the welding platform 2 can be driven to move back and forth. Here, the threaded rod 302 and the threaded seat 303 adopt a ball screw connection method, which can realize the smooth movement and high-precision movement effect of the welding platform 2.

[0029] As an optional implementation, the transverse module includes a horizontal column 305, with roller seats 307 fixedly connected to both ends of the horizontal column 305. A transmission wheel 308 is rotatably connected to each of the two roller seats 307. The two transmission wheels 308 are connected by a transmission belt 309, and the horizontal column 305 is located inside the transmission belt 309. A servo motor 310 for driving the transmission wheel 308 thereon is fixedly installed on the rear side of one of the roller seats 307. By controlling the servo motor 310, the transmission wheel 308 can be controlled to rotate at a suitable angle. At the same time, with the cooperation of the other transmission wheel 308, the transmission belt 309 can be moved left and right, thereby realizing the left and right translation of the welding platform 2.

[0030] Specifically, a slider 306 is fixedly connected to the upper surface of the transmission belt 309, and the slider 306 is slidably connected to the upper side of the cross column 305. The welding platform 2 is fixedly connected to the upper surface of the slider 306, which makes the welding platform 2 more stable when moving left and right through the slider 306.

[0031] Reference Figure 5As shown, a drive box 401 is fixedly connected to the crossbeam plate at the upper end of the column 10. A hollow plate 402 is rotatably connected to the center of the drive box 401. A servo motor 410 for driving the hollow plate 402 to rotate is fixedly installed on the side wall of the drive box 401. A movable block 403 is slidably connected in the hollow plate 402. A tension spring 404 is connected between the end of the movable block 403 and the inner bottom of the hollow plate 402. An inverted U-shaped groove 406 is opened through the side wall of the drive box 401. An I-shaped cylinder 405 is rotatably connected to the end of the movable block 403, and the I-shaped cylinder 405 is slidably connected in the inverted U-shaped groove 406. A connecting arm 407 connected to the connecting head 4 is rotatably connected to the end of the I-shaped cylinder 405. A longitudinal and transverse slider 408 is slidably connected to the connecting arm 407 along the longitudinal direction. A transverse slider 408 is fixedly connected to the lower side wall of the drive box 401. The sliding strip 409 of the groove is connected to the lower end of the connecting arm 407 by the connecting head 4 fixedly connected by the L-shaped support arm. When the servo motor 410 is rotated, the hollow plate 402 rotates with it. Since the I-shaped cylinder 405 is slidably connected in the inverted U-shaped groove 406, the movable block 403 is restricted from extending from the hollow plate 402 and stretching the tension spring 404. At the same time, the connecting arm 407 rises in the longitudinal groove of the longitudinal and transverse slider 408. As the servo motor 410 continues to rotate, the transverse groove of the longitudinal and transverse slider 408 moves laterally on the sliding strip 409 until the connecting head 4 at the lower end of the connecting arm 407 moves to the wire supply point to pick up the wire (it can be picked up by applying glue or hot melting, which is the prior art and well known to those skilled in the art, and will not be described in detail here). It can realize the reciprocating picking up of wire in the form of a PPU robot (capable of running according to a predetermined trajectory, the movement of the actuator).

[0032] Reference Figure 4 As shown in Figure 6, a support rod 501 is fixedly connected to the upper surface of the workbench 1. A telescopic cylinder 502 is fixedly installed at the upper end of the support rod 501. A horizontal arm 503 is fixedly connected to the movable end of the telescopic cylinder 502, and a welding head 5 is fixedly connected to the end of the horizontal arm 503. The other end of the horizontal arm 503 slides vertically on the support rod 501 through a sliding connector. The welding head 5 is driven to move down by the telescopic cylinder 502. The lower end of the welding head 5 contacts the solder wire and the welding point of the wire. The solder wire is melted by its own heat to fix the wire to the circuit board.

[0033] Reference Figure 6As shown, a horizontal base 601 is fixedly connected to the middle of the support rod 501. A telescopic cylinder 602 is fixedly installed at the end of the horizontal base 601, and a slag blowing guide pipe 6 is fixedly connected to the movable end of the telescopic cylinder 602. The end of the slag blowing guide pipe 6 is provided with an opening 604 for the welding head 5 to enter. A hook air pipe 603 for blowing air into the opening 604 is fixedly connected to one side of the slag blowing guide pipe 6. The hook air pipe 603 moves horizontally with the slag blowing guide pipe 6. The telescopic cylinder 602 drives the slag blowing guide pipe 6 to retract. At this time, there are no obstructions below the welding head 5, allowing the welding head 5 to move down smoothly. After welding, the telescopic cylinder 602 can drive the slag blowing guide pipe 6 to reset. The lower end of the welding head 5 enters through the opening 604 and the welding slag on the welding head 5 is blown off by the hook air pipe 603 and discharged from the rear end of the slag blowing guide pipe 6.

[0034] Reference Figure 6 As shown, a support plate 701 is fixedly connected to the upper surface of the workbench 1. A dual-axis cylinder 702 is fixedly installed on the upper side wall of the support plate 701. The wire outlet tube 7 is fixedly connected to the movable end of the dual-axis cylinder 702 through an L-shaped bracket. The wire outlet end of the wire outlet tube 7 is located directly below the welding head 5. The wire outlet end of the wire outlet tube 7 has a downward sloping bend design, which facilitates better contact between the extended solder wire and the circuit board surface. When an appropriate amount of solder wire extends from the end of the wire outlet tube 7 and the dual-axis cylinder 702 is controlled to retract and drive the wire outlet tube 7 to move downward, the lower end of the welding head 5 contacts the solder wire and the welding point of the wire.

[0035] The working principle of this utility model:

[0036] First, the workpiece circuit board is fixed on the surface of the welding platform 2. Then, the solder wire is threaded into the wire outlet tube 7. The digital display controller 8 controls the servo motor 3 410 to drive the connecting arm 407 to move along the inverted U-shaped slide 406. At this time, the connector 4 moves to the welding wire supply point to pick up the wire. Then, the servo motor 3 410 rotates in the opposite direction to drive the wire onto the circuit board on the surface of the welding platform 2. At this time, the slag blowing guide tube 6 is retracted by the telescopic cylinder 2 602 (at this time, there is no obstruction under the welding head 5). Then, the telescopic cylinder 1 5... 02 drives the welding head 5 to move down, and at the same time controls the heating wire feeding station 9 to supply an appropriate amount of solder wire that extends from the end of the wire outlet tube 7. It also controls the double-axis cylinder 702 to retract and drive the wire outlet tube 7 to move down. The lower end of the welding head 5 contacts the solder wire and the wire welding joint. The solder wire is melted by its own heat to fix the wire to the circuit board. Then the welding head 5 rises and the slag blowing guide tube 6 moves below it. The slag on the welding head 5 is blown off by the hook air pipe 603 and discharged from the rear end of the slag blowing guide tube 6. The connector 4 picks up the wire again.

[0037] Simultaneously, by controlling servo motor 304 to drive threaded rod 302 to rotate, the circuit board moves back and forth. At the same time, servo motor 310 rotates to drive transmission belt 309 to move horizontally, thus moving the circuit board left and right, thereby adjusting the soldering points on the circuit board. This process is repeated.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
