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 a welding process for welding LED lamp beads to a PCB board. 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 temperature of the arc is as high as 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 temperature. 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, including a main body bracket, wherein a conveyor is installed inside the main body bracket. The PCB board welding robot drives the limit rack to reciprocate and retract at a fixed distance by controlling the electric telescopic rod to drive the ratchet wheel to rotate unidirectionally, so that the conveyor can perform fixed-distance mobile transportation. At the same time, in conjunction with the operation of the feeding mechanism, multiple stacked circuit boards can be automatically placed 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, so that when the whole is in use, the staff does not need to manually frequently put the PCB board into the fixture or take out the fixture, thereby ensuring the overall welding efficiency and avoiding the high-temperature solder joints after welding from causing damage to the hands of the staff.

[0004] However, when the above method is used to weld the PCB board with the existing welding equipment, since both sides of some boards need to be welded, the double-sided welding of the PCB board can only be manually flipped by the operator. Since high-temperature solder joints will appear on the side where welding is completed, the risk of manual flipping is relatively high, which can easily cause injuries to the hands, making it very inconvenient in actual use. Summary of the invention

[0005] The purpose of the present invention is to provide a fully automatic arc device and welding process for welding LED lamp beads on PCB boards, which can automatically flip the PCB board that needs to be double-sided welded through the provided components, without the need for manual operation, thus avoiding the safety hazards caused by manual operation, and making it more convenient in actual use.

The bidirectional driving screw 309 is fixed to the output shaft of the driving motor 310, and the two clamping shovel frames 308 are provided with threaded holes adapted to the external threads on both sides of the bidirectional driving screw 309, so that the user can directly drive the two clamping shovel frames 308 provided on the matching bracket 304 through the driving motor 310 and the bidirectional driving screw 309, and then realize the corresponding grabbing of the PCB board by driving the two clamping shovel frames 308.

[0048] When using the fully automatic arc equipment for welding LED lamp beads PCB boards of the present embodiment, the driving motor 310 provided on the matching bracket 304 can cooperate with the bidirectional driving screw 309 to drive the clamping shovel frame 308, and then the PCB board can be grabbed, and then the matching bracket 304 can be driven by the telescopic cylinder 303 to drive the grabbed PCB board to move, and at the same time, the corresponding angle and height position of the grabbed PCB board can be adjusted by the rotation of the rotating table 302 on the adjusting bracket 301 and the up and down sliding of the adjusting bracket 301 on the operating frame 101, so that the position of the PCB board can be transferred by the provided transfer member. After the PCB board is loaded, the clamping shovel frame 308 on the matching bracket 304 can be retracted by the telescopic cylinder 303, and then the height position of the matching bracket 304 can be adjusted by the rotation of the rotating table 302 on the adjusting bracket 301 and the up and down movement of the adjusting bracket 301. The adjustment is made so that the matching bracket 304 can clamp and transport the PCB board to be welded transmitted through the two clamping shovel racks 308. At this time, the PCB board after loading is normally welded. After the processing is completed, the PCB board after welding will be pushed to the shelf outer plate 205 by the push-out rack 207. At this time, the PCB board clamped by the matching bracket 304 through the clamping shovel rack 308 can be moved to the placement plate 202 through the corresponding driving mechanism, and then the PCB board to be welded is placed. After that, the welded PCB board placed on the shelf outer plate 205 is clamped and transported, so that the entire loading and unloading process is smoother. When the clamping shovel rack 308 clamps and transports the PCB board on the shelf outer plate 205, the PCB board placed on the placement plate 202 will also be positioned and clamped under the drive of the contact rack 107. The above two processes can be carried out simultaneously, which can reduce the time consumed by the connection between loading and unloading, and greatly enhances the practicality of the entire device.

[0049] See also Fig.10 A fully automatic arc welding process for welding LED lamp beads to PCB boards, using the fully automatic arc welding equipment for welding LED lamp beads to PCB boards, includes the following steps:

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

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

[0052] S3: After the welding on 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 supporting height of the PCB board accordingly to ensure that the PCB board and its corresponding mechanism will not be interfered during flipping. When the PCB board is flipped, the placement component will continue to support the PCB board so that the PCB board can be welded more stably later. After the welding on both sides of the PCB board is completed, the material can be unloaded through the transfer component.

Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
