Description

Technical Field

[0001] This utility model relates to the field of circuit board welding technology, specifically a circuit board welding device that can quickly check the welding status of pins. Background Technology

[0002] Electronic components are soldered onto circuit boards using circuit board soldering equipment, and then the circuit boards with soldered components are mounted onto the casing to manufacture electronic products. In order to ensure the soldering quality of the circuit boards, it is necessary to use inspection components to check the soldering condition of the pins of the electronic components. Therefore, circuit board soldering equipment that can quickly check the soldering condition of the pins has been proposed on the market.

[0003] However, existing circuit board soldering devices that can quickly check the soldering condition of pins rely on heating solder material and pumping molten solder directly to the soldering position. While this can achieve large-scale soldering, it is prone to problems such as cold solder joints and short circuits for small pins. Wave soldering involves large-area contact, making it difficult to precisely control the soldering heat and amount of solder for the pins. Reflow soldering relies on heating air or nitrogen to transfer heat to the solder-coated circuit board, melting the solder to achieve soldering. Although this method is easy to control the temperature, it has shortcomings in checking the soldering condition of pins. It is difficult to inspect the solder joints after soldering and to perform resoldering after inspection, resulting in low soldering efficiency. Therefore, we propose a circuit board soldering device that can quickly check the soldering condition of pins. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This invention provides a circuit board soldering device that can quickly check the soldering status of pins, and has the following beneficial effects:

[0017] (1) This circuit board soldering device, which can quickly inspect the soldering status of the pins, uses a visual inspection instrument and a soldering repair unit. When using the circuit board soldering device, the operator places the circuit board body on the placement slot of the conveyor frame, then starts the conveyor motor. The conveyor motor drives the conveyor shaft to rotate, and the conveyor belt runs and moves the circuit board body. When the circuit board body is located at the position of the gushing trough of the first solder tank, the heating component in the gushing trough heats the solder, and at the same time, the solder pump draws the solder through the solder extraction tube. The solder is then transported through the solder delivery tube to the gushing trough and the position of the soldering gun and gushing out. At this time, the solder is applied to the circuit board body. After soldering, the circuit board is transported to a vision inspection instrument, which inspects the soldering positions. When a cold solder joint is detected, the circuit board is transported to the solder spraying slot. At this point, a laser positioning device locates the area requiring soldering, and an adjusting motor drives an adjusting screw to rotate. The nut seat, due to the rotation direction of the adjusting screw, causes the soldering gun on the sliding frame to slide through the adjusting slot, allowing the solder sprayed from the soldering gun to solder the cold solder joint. This allows the circuit board soldering device to perform soldering inspection and soldering repair on the circuit board, thus improving the practicality and efficiency of the circuit board soldering device.
