Description

Technical Field

[0001] This utility model relates to the field of motherboard welding technology, and in particular to a welding device for PCBA motherboard processing. Background Technology

[0002] PCBA refers to the entire process of a bare PCB board undergoing surface mount technology (SMT) or DIP (Dual In-line Package) component installation. A printed circuit board, also known as a breadboard or breadboard, is the support structure for electronic components and provides the connection between them. Because it is manufactured using electronic printing technology, it is called a printed circuit board. Before the advent of printed circuit boards, the interconnection between electronic components relied on direct wire connections to form complete circuits. Now, breadboards exist primarily as effective experimental tools, while printed circuit boards have become absolutely dominant in the electronics industry. When soldering components such as capacitors and chips onto the motherboard, they are mounted for standardized soldering operations.

[0003] Compared with existing technologies, the existing welding equipment has the following problems: the installation efficiency of existing welding equipment is low, which leads to the need for manual insertion of components onto the motherboard. Even with the use of automated component handling devices, components can only be handled and installed one by one, resulting in low component installation efficiency, which in turn affects the welding efficiency of the motherboard and makes it impractical. To address these issues, we propose a welding equipment for PCBA motherboard processing. Utility Model Content

[0030] Specifically, the transport mechanism includes a base 210, which is fixed to the top of the frame 100 by bolts. The inner wall of the base 210 is provided with a plurality of drive rollers 220, and the outer side of the drive rollers 220 is provided with a conveyor belt 230. The top of the conveyor belt 230 is provided with a main board body 240. By providing a transport mechanism, the drive rollers 220 drive the conveyor belt 230 to rotate, and the main board is transported by the conveyor belt 230. In conjunction with the positioning mechanism, the main board is accurately moved to the set position.

[0031] Specifically, the positioning mechanism includes a mounting base 310, which is fixed to the top of the frame 100 by bolts. A cylinder A320 is fixed to one side of the mounting base 310, and a drive seat 321 is fixed to one end of the cylinder A320.

[0032] Specifically, the adjustment mechanism includes a mounting bracket 510, which is bolted to the outside of the frame 100. A mounting frame 520 is bolted to the top of the mounting bracket 510.

[0035] Working principle: During use, the host machine 110 controls the operation of the equipment. The drive roller 220 drives the conveyor belt 230 to rotate, which transports the main board. The cylinder A320 drives the drive seat 321 to move, which in turn moves a pair of positioning plates 351 to the main board. The cylinder B340 drives the connecting seat 341 to move downward, which in turn moves the positioning plates 351 to the side of the main board. The positioning plates 351 move to adjust the main board to the required installation position. Multiple conveyors 420 supply and transport different types of components. The drive motor A530 drives the lead screw A531 to rotate. The sliding seat A540 of the lead screw A531 moves laterally, which in turn moves the installation mechanism laterally. The drive motor B560 drives the lead screw B561 to rotate. The rotation of 561 drives the sliding seat B570 to move longitudinally, which in turn drives the mounting mechanism to move longitudinally, realizing the horizontal position adjustment of the mounting mechanism. In conjunction with the electric telescopic rod B610 to adjust the height of the clamp 650, the omnidirectional position adjustment of the clamp 650 is realized. The mounting mechanism is moved above the corresponding component through the adjustment mechanism. The electric telescopic rod B610 drives the adjusting seat 620 to move down, which in turn drives the clamp 650 to move down, and the clamp 650 clamps the component. The adjusting mechanism transfers the clamp 650 to the next component. The stepper motor 630 drives the rotating seat 640 to rotate, which in turn drives the clamp 650 to rotate, realizing the switching operation of the clamp 650. It can clamp new components. Repeating this operation can complete the clamping and transportation of multiple components at one time and install them onto the motherboard.
