Description

Technical Field

[0002] A circuit board, also known as a printed wiring board or printed circuit board, is an electronic component that uses non-conductive material as a substrate and etches and sticks conductive materials such as copper on its surface to form a conductive path. A circuit board is mainly composed of pads, vias, mounting holes, wires, components, connectors, fillings, electrical boundaries, etc. Pads are metal holes used to solder component pins. Vias are divided into metal vias and non-metal vias, which are used to connect component pins between layers.

[0003] The mounting holes are used to fix the circuit board, the wires are the electrical network copper films that connect the pins of the components, the connectors are used to connect the components between the circuit boards, and the copper filling used for the ground network can effectively reduce the impedance. The electrical boundary determines the size of the circuit board, and all components cannot exceed this boundary. The circuit board error-proofing welding equipment is an automated equipment dedicated to ensuring that no errors occur during the circuit board welding process.

[0004] Most of the existing technologies require operators to perform welding work with handheld welding equipment, which results in poor fixing effect on the parts to be processed, and it is easy to cause the parts to shake and cause welding errors, thereby reducing the welding quality and the welding efficiency of the welding equipment. When using welding wire to process parts, welding wire residue will be generated, which will fall and be distributed on the welding equipment. A large amount of welding wire residue will accumulate over a long period of time and is inconvenient to clean.

[0005] Therefore, it is urgent to improve the welding equipment of the circuit board to solve the above-mentioned problems. Summary of the invention

[0051] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0052] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0053] The above description shows and describes several preferred embodiments of the present invention, but as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field. Changes and variations made by those skilled in the art do not depart from the spirit and scope of the present invention, and should be within the scope of protection of the claims attached to the present invention.
