Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and in particular to a fully automatic arc equipment and welding process for welding LED lamp beads to PCB boards. Background Art

[0002] Arc welding is a welding method that uses the high temperature generated by an electric arc to melt metal, thereby achieving metal connection. During the arc welding process, an arc is generated between the electrode and the workpiece. The arc temperature can reach thousands of degrees, causing the local metal of the electrode and the workpiece to melt rapidly. At the same time, under the action of the arc, the gas around the welding area is ionized to form a protective gas to prevent the metal from being oxidized at high temperatures. As the electrode moves, the molten metal gradually cools and solidifies to form a solid weld.

[0003] The existing patent with publication number CN117399860A discloses a PCB board welding robot, which includes a main body bracket, and a conveyor is installed inside the main body bracket. The PCB board welding robot controls the electric telescopic rod to drive the reciprocating and fixed-distance extension of the limit rack to drive the unidirectional rotation of the ratchet, so that the conveyor can move and transport at a fixed distance. At the same time, in conjunction with the operation of the feeding mechanism, it can automatically place multiple stacked circuit boards on multiple mounting tables in sequence. At the same time, in conjunction with the coordinated operation of the positioning mechanism and the trigger mechanism, the circuit boards on the mounting tables are stably clamped to ensure stability during welding. At the same time, the circuit boards welded on the mounting tables can be automatically loosened and removed. When the whole is in use, there is no need for the staff to frequently manually place the PCB board into or remove the clamp, thereby ensuring the overall welding efficiency and avoiding the high-temperature solder joints after welding from causing damage to the staff's hands.

[0004] However, when using the above method to solder PCBs using existing soldering equipment, since some panels need to be soldered on both sides, double-sided soldering on the PCB can only be performed manually by the operator. Since high-temperature solder joints will appear on the soldered side, manual flipping is risky and can easily cause injury to the hands, making it very inconvenient during actual use.

At this time, since the side of the contact frame 107 that cooperates with the side of the PCB board is provided with the rubber roller 110, when the driving frame 108 and the clamping plate 109 clamp the two sides of the PCB board, the PCB board can quickly adjust its position and cooperate with the clamping plates 109 on both sides through the rotation of the rubber roller 110.

[0038] When the fully automatic arc equipment for soldering LED lamp beads PCB boards of this embodiment is used, the placing component cooperates with the transferring component to load the PCB board, and then the clamping cylinders 105 on both sides drive the corresponding connecting frame 106 and the contact frame 107 to cooperate with the two sides of the PCB board to complete the clamping and limiting of the corresponding two sides of the PCB board. After the two contact frames 107 are fully matched with the two sides of the PCB board, the driving motor 114 provided on each of the contact frames 107 can drive the corresponding two-way driving screw 113 to rotate, and then the rotation of the two-way driving screw 113 drives the two driving frames 108 and the clamping plate 109 on the corresponding contact frame 107 to clamp and limit the other two sides of the PCB board.

After the PCB board is placed on the shelf outer plate 205, the PCB board is moved to the shelf outer plate 205 by the push-out rack 207.

[0049] See also Figure 10 A fully automatic arc welding process for LED lamp bead PCB board welding, using the fully automatic arc welding equipment for LED lamp bead PCB board welding, includes the following steps:

[0050] S1: The PCB to be soldered is transferred to the placement member by a transfer member, which supports the PCB. Then, the clamping cylinders 105 provided on the turning columns 104 on both sides drive the connecting frames 106 and contact frames 107 provided on both sides to cooperate with the placed PCB.

[0051] S2: Clamping the two sides of the PCB board by the contact frames 107 on both sides, and then limiting and clamping the other two sides of the PCB board by the fastening components, and then welding the clamped PCB board by the welding equipment 103;

[0052] S3: After the welding of one side of the PCB board is completed, the flip component can simultaneously drive the flip columns 104 on both sides to rotate, and then the clamped PCB board is flipped by the rotation of the flip columns 104. During the flipping process, the placement component will adjust the support height of the PCB board accordingly to ensure that the PCB board and its corresponding mechanism will not be interfered with during the flipping. When the PCB board is flipped, the placement component will continue to support the PCB board so that the PCB board can be soldered more stably later. After the welding of both sides of the PCB board is completed, the material can be unloaded through the transfer component.

A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
