Description

Technical Field

[0001] The invention relates to the technical field of welding tooling, and in particular to a welding tooling for an electronic component processing assembly line. Background Art

[0002] In the process of processing electronic components, a crucial link is to accurately solder the electronic components to the circuit board to build a functional and stable electronic circuit. This welding operation requires extremely high precision and stability, because any slight deviation may cause the circuit performance to deteriorate, or even cause serious problems such as short circuit and open circuit.

[0003] In order to achieve precise welding between electronic components and circuit boards, it is usually necessary to fix the position of the circuit board to ensure that the circuit board does not move or deviate during the welding process. However, most of the existing circuit board fixing methods use a top clamping structure. Although this structure can fix the circuit board to a certain extent, it also has many shortcomings.

[0004] First, the clamping structure often clamps and fixes the circuit board through mechanical force. This clamping force can easily cause physical damage to the circuit board, such as indentation and deformation. These damages not only affect the aesthetics of the circuit board, but are also likely to damage the circuit structure on the circuit board, causing circuit performance degradation or failure. Secondly, the clamping structure may hinder the normal operation of welding tools during the welding process, such as the movement of the soldering iron tip and the placement of welding materials, which increases the difficulty of welding operations and reduces welding efficiency. It may also cause welding quality problems, such as poor welding and cold soldering.

The position adjustment of the limit mechanism is realized as the positions of the four movable slide bars 22 move. When the position of the limit mechanism is fixed, the staff removes the circuit board from the conveyor belt 1, and inserts the rear side ends of the circuit board into the limit grooves 31 of the two placement grooves 30 on the rear side, and pushes the limit plate 29 backward. As the limit plate 29 moves backward, the abutting spring 34 on the rear side is stretched.

Under the action of the two abutting springs 34 on the rear side, the front side end of the circuit board is moved to the two limit grooves 3 on the front side. 1, and place the electronic components to be welded on the circuit board; as the mobile motor 10 drives the mobile gear 11 to rotate, the mobile gear 11 cooperates with the transmission gear ring 9 to drive the circuit board to rotate to the bottom of the dust removal motor 16, and the dust removal motor 16 is used to drive the fan to rotate, and the dust on the surface of the product is raised, and the dust is sucked away by the dust suction pump 17 and the dust suction frame 18; the staff installs the circuit board on the next fixing mechanism 14 and places the electronic components to be welded; under the action of the mobile motor 10 and the mobile gear 11, the dust-removed circuit board is driven to rotate to the bottom of the welding frame 8, and the mobile mechanical arm 12 and the welding head 13 in the welding frame 8 are used to weld the electronic components at the designated position. After welding, the product moves to the bottom of the heat dissipation motor 15, and the heat dissipation motor 15 is used to drive the fan to rotate, thereby realizing the heat dissipation of the welded product. When the welded product moves to the front side of the staff after the welding, the staff can remove the welded product and place it on the conveyor belt 2 3 after the quality inspection is completed.
