Technical Field

[0001] The utility model relates to the technical field of USB connectors, in particular to a USB SMT mounting tool. Background Art

[0002] In the electronics manufacturing industry, surface mount technology (SMT) has become a key process for assembling electronic components. Due to its high density, miniaturization, and high degree of automation, SMT has been widely used in various electronic products. SMT is particularly indispensable for small, delicate electronic components like USB ports.

[0003] However, in practice, traditional SMT placement methods often suffer from low precision, inefficiency, and component damage when placing these delicate components. This is especially true for critical components like USB ports, where even the slightest deviation can lead to unstable connections or signal transmission issues, impacting overall product performance.

[0004] Existing SMT placement methods and carriers also exhibit some shortcomings when handling USB interfaces. For example, inaccurate positioning can lead to positional deviation during the placement process, thus affecting final product quality. Furthermore, the way traditional carriers secure USB components is not reliable. During high-speed placement, components may become loose or even fall off, increasing the defect rate during production, such as causing poor soldering and other issues, and thus reducing overall production efficiency.

[0025] The first placement groove 2 is provided with a positioning pin 21 for fixing the PCB board 7; the second placement groove 3 is provided with a positioning block 31 for fixing the USB interface 8; the bottom of the PCB board 7 is provided with a magnet 4 at the corresponding position of the second placement groove 3; the PCB board 7 is provided with a positioning hole that cooperates with the positioning pin 21.

[0026] Specifically, when using the USB SMT mounting tool described in this embodiment, the PCB board 7 is placed in the first placement slot 2 of the main body 1 using the positioning pins 21, and the USB interface 8 is accurately placed in the second placement slot 3 of the main body 1 using the placement machine's visual positioning system. It is then clamped by the positioning block 31. In addition, the magnet 4 will firmly adsorb the USB interface 8 in the second placement slot 3 of the main body 1, so that the pins of the USB interface 8 and the pads of the PCB board 7 are perfectly aligned. After the PCB board 7 and the USB interface 8 are placed, the main body 1 is soldered through reflow soldering, and the product can be removed after completion.

[0027] In this embodiment, the PCB board 7 is placed in the first placement groove 2 of the main body 1 through the positioning pin 21, and the USB interface 8 is fixed in the second placement groove 3 through the magnet 4 and the positioning block 31, so that the overall structure is stable and reliable, and the PCB board 7 and the USB interface 8 are prevented from loosening.

This arrangement enables the magnet 4 to effectively attract the USB port 8 to the second placement slot 3.

[0034] In the USB SMT mounting tool described in this embodiment, clearance notches 5 are provided on both sides of the body 1. The depth of the clearance notches 5 is greater than the depth of the first placement slot 2. This arrangement facilitates removal of the entire PCB 7 from the first placement slot 2 through the clearance notches 5 after reflow soldering.

[0035] In the USB SMT mounting device described in this embodiment, the main body 1 is provided with a plurality of fixing holes 6. This arrangement facilitates fixing the main body 1 to the reflow soldering equipment.

[0036] In the USB SMT mounting device described in this embodiment, the magnet 4 is a high-temperature resistant strong magnet. This configuration can prevent damage to the magnet 4 during the reflow soldering process and can effectively fix the USB port 8.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model.
