Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and particularly to a fully automatic laser welding workstation for pins of a radio frequency connector. Background Art

[0002] Radio frequency and wireless systems are widely used in all modern applications. Different types of radio frequency connectors provide interconnections between modules and systems through board-to-board, board-to-cable, or module-to-board connections. A radio frequency connector is a physical component of a device that provides convenient and standardized interconnections at nodes, rather than directly crimping, soldering, or clamping connections at ports. A radio frequency connector mainly consists of a central pin, an insulating gasket, and an external conductive housing. The pins are generally installed in the radio frequency connector by means of laser welding or crimping, etc. The radio frequency connector is usually in a T shape or a cross shape.

[0003] Currently, when welding the pins of a radio frequency connector, it is usually done manually. The radio frequency connector is fixed sequentially, and the laser welding equipment is operated to achieve the welding of the pins. This not only has cumbersome operations, but also extremely low welding efficiency of the pins. In addition, since the position or direction of each fixation of the radio frequency connector is different, when welding different pins, it is necessary to frequently adjust the position and direction of the laser welding equipment, resulting in a low degree of intelligence in pin welding, and it is also easy to have errors during welding. At the same time, frequent manipulation of the welding equipment will also accelerate the damage of the equipment and affect the service life of the welding equipment. Summary of the Invention

On the one hand, the automatic feeding of the RF connector is realized, and on the other hand, the stability of the welding position of the RF connector can be guaranteed.

At the same time, during the feeding process, the residual welding slag can be cleaned through the linkage assembly to ensure the welding quality of the subsequent RF connector pins.

[0018] 2. For this fully automatic laser welding workstation for RF connector pins, through the locking mechanism, the angle can be fixed after the RF connector is welded, so that during the rotation process, the RF connector can fall onto the discharging and conveying device through the discharging channel, thereby realizing the automatic discharging of the RF connector, improving the automation degree of the equipment, and further improving the welding efficiency of the RF connector pins.

[0019] 3. For this fully automatic laser welding workstation for RF connector pins, through the fastening mechanism, the RF connector can be fastened when it stops rotating to avoid displacement during the welding process. While simplifying the welding process of the RF connector pins, the accuracy and stability of the welding position of the RF connector can be guaranteed; in addition, during the welding process, the arc-shaped cylinder can be driven to drive the baffle to rotate to block the RF connector during conveying, avoiding the situation of stacked feeding of the RF connector.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0033] Embodiment: Refer to Figures 1-9, a fully automatic laser welding workstation for RF connector pins, includes a base 1, a feeding conveyor device 3, a discharging conveyor device 4 and a fixing frame 10 fixedly connected to the base 1. It further includes: a turntable 11 rotatably connected to the fixing frame 10, an intermittent driving mechanism 12 rotatably connected to the fixing frame 10 and connected to the shaft end of the turntable 11. A linkage assembly is provided between the intermittent driving mechanism 12 and the fixing frame 10 and the feeding conveyor device 3 and the discharging conveyor device 4, and the turntable 11 is driven by the intermittent driving mechanism 12 to rotate intermittently along the conveying direction of the feeding conveyor device 3; a limiting frame 20 rotatably connected to the turntable 11 for placing RF connector pins. Isolation frames 18 are symmetrically and fixedly connected to the fixing frame 10, and permanent magnets 19 are fixedly connected to the isolation frames 18. A locking mechanism is provided between the limiting frame 20 and the turntable 11 for locking the shaft end of the limiting frame 20 when the limiting frame 20 rotates to the area of the permanent magnet 19. Among them, a fastening mechanism is provided between the turntable 11 and the limiting frame 20 for fastening the RF connector pins in the limiting frame 20 when the turntable 11 stops rotating.

[0034] It should be noted that the RF connector pins are generally T-shaped or cross-shaped, and the pins are usually welded at the horizontal position of the T-shape or one end of the cross-shape (the length of one end of the welding position is less than that of the other end, but the diameter is slightly larger). It also includes a welding station 2 fixedly connected to the base 1. The welding station 2 includes welding equipment and a control panel. Among them, the welding head of the welding equipment is close to the upper limiting frame 20. A discharging channel 37 is fixedly connected to the inner wall of the discharging conveyor device 4. The discharging channel 37 is inclined, and the end of the discharging channel 37 is close to the limiting frame 20. The size of the discharging channel 37 matches the size of the turntable 11. The discharging channel 37 is located between the permanent magnets 19 on both sides. The height and position of the welding head can be adjusted and welding operations can be achieved by operating the control panel. This is a conventional means in the prior art, so it will not be elaborated. In addition, a feeding device can be set at a position close to the feeding conveyor device 3 to realize automatic feeding of RF connectors, such as a vibrating feeding tray, etc. The feeding conveyor device 3 and the discharging conveyor device 4 both include conveying rollers, conveyor belts and frames. The specific structure can refer to the technical solutions in the prior art, and the conveyor belt is inclined to facilitate the feeding and discharging of RF connectors.

[0035] Refer to Figure 2 、 Figure 4 and Figure 5, the intermittent drive mechanism 12 includes a limit disk 121 and an adjustment disk 125 rotatably connected to the fixed frame 10. On the side of the limit disk 121 away from the fixed frame 10, a fixed disk 122 is fixedly connected. On the side of the fixed disk 122 close to the limit disk 121, a drive rod 123 is fixedly connected. On the side of the limit disk 121 close to the drive rod 123, a sector-shaped groove 124 is provided. On the adjustment disk 125, multiple arc-shaped grooves 126 matching the limit disk 121 are provided. On the adjustment disk 125, multiple drive grooves 127 matching the drive rod 123 are provided. Among them, the adjustment disk 125 is connected to the shaft end of the turntable 11. The outer wall of the limit disk 121 is in contact with the arc-shaped groove 126. The linkage assembly includes drive wheels 15 rotatably connected to the sides of the feeding conveyor 3 and the discharging conveyor 4 close to the fixed disk 122. On the side of the fixed disk 122 close to the drive wheel 15, a deflector wheel 13 is fixedly connected. On the side of the fixed frame 10 close to the deflector wheel 13, a linkage wheel 14 is rotatably connected. A belt 16 is sleeved between the drive wheel 15, the deflector wheel 13, and the linkage wheel 14. Among them, the drive wheel 15 is connected to the shaft ends of the feeding conveyor 3 and the discharging conveyor 4. A drive motor 5 is provided on the feeding conveyor 3. When the drive wheel 15 rotates, the deflector wheel 13 is driven to rotate in the opposite direction of the drive wheel 15 through the linkage wheel 14 and the belt 16. A dust suction device 17 connected to the linkage wheel 14 is fixedly connected to the base 1.

[0036] When the RF connector is on the feeding conveyor 3, driving the feeding conveyor 3 can convey the RF connector. At the same time, the limit disk 121 and the fixed disk 122 are driven to rotate in the reverse direction. Under the action of the drive rod 123 and the drive groove 127, the turntable 11 is driven to rotate in the same direction as the feeding conveyor 3. When the limit disk 121 and the fixed disk 122 rotate one circle, under the action of the sector-shaped groove 124 and the arc-shaped groove 126, the turntable 11 can be stopped and stay in place to facilitate welding the RF connector. In addition, according to the welding time, the conveying speed of the feeding conveyor 3 and the diameter ratio between the drive wheel 15 and the deflector wheel 13 can be adjusted so that the staying time of the turntable 11 matches or is slightly longer than the welding time required; in addition, since welding slag will appear during the welding process and is likely to remain on the limit frame 20, during the conveying process, when driving the linkage wheel 14 to rotate, the dust suction device 17 will be driven. The diameter ratio between the linkage wheel 14 and the drive wheel 15 can be adjusted according to the rotation speed required for the dust suction device 17 to generate a certain suction force, that is, when the limit frame 20 rotates to the position of the dust suction device 17, the suction force generated by the dust suction device 17 will clean and collect the welding slag remaining on the limit frame 20, thereby ensuring the welding quality of the subsequent RF connectors.

[0037] Refer to Figures 6-8, the locking mechanism includes a rotating groove 23 formed in the turntable 11. A positioning disk 24 is rotatably connected inside the rotating groove 23. A plurality of sliding grooves 25 are formed on one side of the turntable 11 close to the rotating groove 23. A first spring 26 is fixedly connected inside the sliding groove 25. The end of the first spring 26 is fixedly connected with a slider 27 slidably connected to the sliding groove 25. One side of the slider 27 away from the first spring 26 is fixedly connected with a positioning rod 28. A positioning groove 29 matching the positioning rod 28 is formed on one side of the positioning disk 24 close to the sliding groove 25. Among them, the shaft end of the limiting frame 20 is connected to the positioning disk 24. The slider 27 has magnetism, and the sides of the slider 27 and the permanent magnet 19 close to each other have the same magnetism.

[0038] During the rotation of the limiting frame 20, it is always in a horizontal state, so that the welding position of the RF connector is always close to the welding head. When welding, the limiting frame 20 at the welding position will rotate between the two permanent magnets 19 on both sides. Under the action of the permanent magnet 19, it will drive the slider 27 to move towards the positioning groove 29 until the positioning rod 28 is driven to be inserted into the positioning groove 29. At this time, the limiting frame 20 always maintains this angle. First, it can ensure that the limiting frame 20 will not rotate during the welding process. When the welding is completed and the limiting frame 20 continues to rotate, the angle of the limiting frame 20 will change with the rotation of the turntable 11, that is, it will gradually tilt towards the blanking conveying device 4. When it rotates to a certain angle, the RF connector will fall out of the limiting frame 20 and, under the action of the blanking channel 37, fall onto the blanking conveying device 4, thereby realizing the automatic blanking of the RF connector. It should be noted that the isolation frame 18 has the function of isolating magnetism, avoiding the mutual repulsion between the permanent magnet 19 and the slider 27 in the inclined direction, so as to ensure the stability of the locking of the limiting frame 20.

[0039] Refer to Figure 6 、 Figure 7 and Figure 9, the fastening mechanism includes multiple groups of installation grooves 30 formed in the turntable 11. A second spring 31 is fixedly connected inside the installation groove 30. The end of the second spring 31 is fixedly connected with a centrifugal block 32 that is slidably connected to the installation groove 30. A control switch 33 is fixedly connected to the side of the installation groove 30 away from the second spring 31. Among them, the number of installation grooves 30 is the same as the number of limit frames 20. When the turntable 11 rotates, the centrifugal block 32 moves towards the side of the second spring 31. It also includes a sealing groove 34 formed in the limit frame 20. Electric telescopic rods 35 are symmetrically and fixedly connected inside the sealing groove 34. The end of the electric telescopic rod 35 is fixedly connected with a fastening ring 36 that is slidably connected to the sealing groove 34. Among them, the electric telescopic rod 35 is electrically connected to the control switch 33 in the corresponding direction. The fastening ring 36 and the sealing groove 34 are connected in a sealed manner. The limit frame 20 is provided with a hole that matches the small size of the RF connector pin. And the sealing groove 34 communicates with the hole on the limit frame 20. A diversion funnel 21 that matches the hole is fixedly connected to the limit frame 20. A counterweight 22 is fixedly connected to the side of the limit frame 20 away from the diversion funnel 21.

[0040] Under the action of the counterweight 22, the limit frame 20 always maintains a horizontal state during the rotation process. The diversion funnel 21 can ensure that the RF connector can be stably inserted into the inner hole of the limit frame 20 during the feeding process. In addition, when the limit frame 20 rotates, the centrifugal block 32 will do centrifugal motion under the action of centrifugal force, so as to disengage from the control switch 33 to ensure that the RF connector can be stably conveyed into the hole of the limit frame 20. When the limit frame 20 stops rotating, the centrifugal block 32 will move towards the initial position under the action of the second spring 31, so as to contact the control switch 33 and drive the electric telescopic rod 35 to extend outwards, thereby fastening the RF connector through the fastening ring 36 to avoid the situation of the RF connector shifting during welding. It should be noted that in this application, the design of gas pipeline connection or electrical circuit connection can be realized by means of a slip ring. That is to say, even when the turntable 11 and the limit frame 20 are in a rotating state, it can ensure the stable transportation of gas and the on - circuit state of the circuit.

[0041] Refer to Figures 1-3, there are symmetrically rotatably connected baffles 6 on the feeding and conveying device 3. A curved air cylinder 7 is fixedly connected between the baffle 6 and the inner wall of the feeding and conveying device 3. Among them, the curved air cylinder 7 is connected to the sealing groove 34 through a pipeline. And when the sealing groove 34 is in a negative pressure state, the curved air cylinder 7 extends outwards. The center of the curved air cylinder 7 and the axis of the baffle 6 are on the same straight line. On one side of the feeding and conveying device 3 close to the end of the baffle 6, there are symmetrically fixedly connected guide rows 8. Multiple groups of guide wheels 9 are rotatably connected to the guide rows 8. Among them, one end of the guide row 8 close to the baffle 6 is inclined. The other end of the guide row 8 is close to the limit frame 20. The distance between the two guide rows 8 is greater than the small size of the RF connector pins and less than the large size of the RF connector pins.

[0042] It should be explained that the air inlet position of the curved air cylinder 7 is at one end close to the baffle 6. Therefore, when gas is conveyed into the curved air cylinder 7, it will drive the curved air cylinder 7 to contract inwards. When inhaling, it can drive the curved air cylinder 7 to extend outwards. This is a conventional means in the prior art, so it will not be elaborated. After the RF connector is placed on the feeding and conveying device 3 by the feeding device, under the action of the feeding and conveying device 3, it will drive the RF connector to move towards the guide row 8 side. And under the action of the baffle 6, the small-size part of the RF connector can enter between the two guide rows 8. Under the action of the guide wheels 9, the RF connector can slide along the guide row 8 towards the limit frame 20 side. Under the action of the diversion hopper 21, it will finally fall into the hole on the limit frame 20. When the RF connector pins are welded, through the change of the air pressure in the sealing groove 34, it will drive the curved air cylinder 7 to extend outwards, driving the baffle 6 to block the RF connector to prevent the RF connector from continuing to be conveyed. After welding is completed, the RF connector can continue to be conveyed. It should be explained that the feeding device will not place multiple RF connectors on the feeding and conveying device 3 at the same time. Therefore, there will be no situation of RF connector accumulation at the baffle 6.

[0043] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
