DETAILED DESCRIPTION

[0026] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the accompanying drawings and specific embodiments are only exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0027] like Figure 1 to Figure 7 As shown, the embodiment of the present application discloses a 5G antenna isolation strip automatic welding device, including a control unit 100, a welding unit 200 and a tin delivery unit 300, wherein the control unit 100 is composed of electronic equipment such as a PLC inverter, which is responsible for controlling the action of the welding gun and can be arranged in an electric control cabinet at the bottom of the frame. The welding unit 200 can be arranged in the middle of the equipment frame for easy operation. The tin delivery unit is arranged at the top of the equipment frame to provide tin raw materials to the welding gun 1.

[0028] Among them, the welding part 200 includes a plurality of welding guns 1 and a PCB clamping plate 2. The plurality of welding guns 1 are slidably connected to the vertical guide rail 3 and are transmission-connected to the longitudinal drive mechanism 4, and the PCB clamping plate 2 is slidably connected to the horizontal guide rail 5 and is transmission-connected to the transverse drive mechanism 6. Both the longitudinal drive mechanism and the transverse drive mechanism can adopt an electric screw structure, that is, the screw is driven by a motor for transmission. This structure is relatively common, so it is not repeated here. The tin feeding part 300 includes a plurality of tin feeding machines 7 (or tin-breaking tin feeding machines), each of which is a tin feeding machine 7 for a welding gun 1. The transverse drive mechanism 6 and the longitudinal drive mechanism 4 are both connected to the control unit 100 by signal, and the control unit 100 coordinates and controls the transverse drive mechanism 6 and the longitudinal drive mechanism 4 to complete the welding action and the movement action of the circuit board. In this embodiment, the welding part 200 is provided with 7 welding guns 1, and the 7 welding guns are operated simultaneously, so that the original 7 actions are completed in one go, thereby improving the welding efficiency.

[0029] Preferably, the PCB clamping plate 2 can be tilted to allow the solder to fully contact the PCB board solder joints, making the welding more firm and the welding effect better. In this embodiment, the inclination angle of the PCB clamping plate 2 is 30 degrees.

[0030] In order to allow the relative positions of multiple welding guns 1 to be adjusted according to the needs of different types of 5G antennas, the welding guns 1 can be connected to a position adjustment mechanism, and the position adjustment mechanism can be slidably matched with the vertical guide rail 3.

[0031] Specifically, the position adjustment mechanism may include a longitudinal adjustment component. The longitudinal adjustment component includes a longitudinal adjustment screw 8, a longitudinal guide rod 9 and an adjustment fixing block 10. The adjustment fixing block 10 is slidably connected to the vertical guide rail 3. The longitudinal adjustment screw 8 passes through the adjustment fixing block 10 and is connected to the adjustment fixing block 10 by means of a nut. The lower end of the longitudinal adjustment screw 8 is connected to the welding gun 1. The longitudinal guide rod 9 can slidably pass through the adjustment fixing block 10. The lower end of the longitudinal guide rod 9 is connected to the welding gun 1. The longitudinal guide rod 9 is parallel to the longitudinal adjustment screw 8. By screwing the nut on the adjustment fixing block 10, the longitudinal adjustment screw 8 can drive the welding gun 1 to rise or fall, thereby adjusting the height of the welding gun 1.

[0032] Furthermore, the position adjustment assembly may also include a transverse adjustment assembly. The transverse adjustment assembly includes a transverse adjustment screw 11, a transverse guide rod 12 and a transverse adjustment fixing plate 13. The transverse adjustment screw 11 passes through the adjustment fixing block 10 and is connected to the adjustment fixing block 10 by means of a nut. The transverse guide rod 12 can slidably pass through the adjustment fixing block 10. The transverse adjustment screw 11 and the transverse guide rod 12 are arranged in parallel on the transverse adjustment fixing plate 13. The transverse adjustment fixing plate 13 is slidably connected with the vertical guide rail 3 by means of a slider. By adjusting and screwing the nut on the adjustment fixing block 10, the adjustment fixing block 10 can drive the welding gun 1 to move left and right, thereby adjusting the horizontal position of the welding gun 1.

[0033] In order to prevent the welding gun 1 from crushing the PCB board when moving up and down, the welding gun 1 can be connected to the position adjustment component through a buffer component. The buffer component includes a soldering iron fixing frame 14 and a soldering iron fixing base plate 15. The welding gun 1 is fixed on the soldering iron fixing frame 14, and the soldering iron fixing frame 14 is slidably matched on the soldering iron fixing base plate 15. The upper end of the soldering iron fixing frame 14 is connected to the fixing seat 16 by means of elastic parts such as springs, and a limited position block 17 is set below the soldering iron fixing frame 14. By setting the buffer component, the welding gun 1 can move freely up and down within a certain range, and its maximum pressure on the circuit board does not exceed the weight of the welding gun itself, so that the circuit board can be protected from being crushed.

[0034] In order to fix the direction of the solder wire, a tin feeding fixture 18 is provided on the side of the welding gun 1, and a wire feeding tube 19 is provided on the tin feeding fixture 18. The tin feeding machine 7 feeds the solder to the end position of the welding gun 1 through the wire feeding tube 19.

[0035] In a possible embodiment, a blow pipe 20 is fixed on the tin delivery fixture 18, and the blow pipe 20 is connected to an air source such as an air pump. A tin blowing box 21 is provided on one side of the PCB mounting clamp 2. After welding is completed, the residual solder at the end of the welding gun 1 can be blown away by blowing air through the blow pipe 20.

[0036] The working process of the device is briefly described below: After the PCB board is fixed on the PCB clamping plate 2, ensure that the tin feeder 7 feeds the soldering gun 1 normally. Then, according to the pre-set program in the control unit 100, the soldering gun 1 is controlled to move above the PCB board, and multiple soldering guns 1 perform soldering operations at the same time. After soldering is completed, the soldering gun 1 is reset to the top of the tin blowing box 21, and the air blowing pipe 20 blows away the residual solder, completing the entire operation.

[0037] In summary, the embodiment of the present invention drives multiple welding guns to perform welding simultaneously through the longitudinal drive mechanism and the transverse drive mechanism, which greatly improves the welding efficiency compared to the existing manual welding, and has a simple design, easy installation and stable structure.
