DETAILED DESCRIPTION

[0033] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings; however, the example embodiments can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the figures, and thus description of the same will be simplified or omitted.

[0034] The terms "one", "a", "an", "the", and "said" are used to indicate one or more of something; the terms "comprising", "having", and "including" are used to indicate an open-ended inclusion of one or more of something; and the use of "or" means "and / or", unless otherwise indicated.

[0035] Reference will be made to Figures 1 to 6This utility model provides a surface mount device, including a fixing body 1, at least two fixing holes 2, and a boss 3. The fixing body 1 has a first surface 11 and a second surface 12 facing each other, and the first surface 11 and the second surface 12 are connected by a side surface 13. The first surface 11 of the fixing body 1 is provided with at least two fixing holes 2. The fixing holes 2 are used to fix the components to be mounted, including Pogo pins 9. Before mounting, components such as Pogo pins 9 can be fixed in the fixing holes 2. During the surface mount soldering process, due to the fixing effect of the fixing body 1, components such as Pogo pins 9 will not tilt.

[0036] A boss 3 is located at the bottom of the fixing hole 2, and an annular groove 4 is formed between the boss 3 and the side wall of the fixing hole 2. In this embodiment of the invention, a boss 3 is provided at the bottom of the fixing hole 2, and an annular groove 4 is formed between the boss 3 and the side wall of the fixing hole 2. The boss 3 can position the component to be mounted, ensuring that the component extends into the fixing hole 2 to a predetermined size, thus ensuring the accuracy of the component soldering to the circuit board 10. The annular groove 4 can avoid the component to be mounted, preventing the rounded corners formed between the side wall and the bottom of the fixing hole 2 due to processing or other reasons from affecting the component to be mounted. Because the annular groove 4 avoids the component to be mounted, the boss 3 can accurately position the component to be mounted.

[0037] The placement device of this utility model embodiment can be used for manual placement or automatic placement. In the exemplary embodiment, the component to be placed is fixed in the fixing hole 2, and then the operator places the placement device with the component to be placed fixed in the corresponding position on the circuit board 10, so that the component to be placed corresponds to the placement position, thereby realizing manual placement.

[0038] In this embodiment of the utility model, see Figures 2 to 6 The second side 12 and the side side 13 may have a chamfer.

[0039] In some embodiments, the second surface 12 has an adsorption portion for being picked up by the placement head of a placement machine. With the adsorption portion on the second surface 12, the placement head of the placement machine can adsorb the placement device and move it to the corresponding position on the circuit board 10, aligning the component to be placed with the placement position, thus achieving automatic placement. The adsorption portion can be a flat surface that facilitates the placement head's pickup. The size of the adsorption portion can be at least not smaller than the suction area of ​​the placement head to ensure proper pickup. The adsorption portion can be located in the middle of the second surface 12. The second surface 12 can be entirely flat.

[0040] In some embodiments, see Figure 3The mounting body 1 also has a venting structure. When the component to be mounted is fixed in the mounting hole 2, the annular groove 4 is connected to the outside of the mounting body 1 through the venting structure. By setting the venting structure, the annular groove 4 is prevented from forming a closed space, which would affect the installation of the component to be mounted into the mounting hole 2, or affect the disassembly of the mounting device after soldering.

[0041] In some embodiments, see Figure 3 The venting structure includes a vent 5, one end of which is located within the annular groove 4, and the other end is located on the second surface 12 and / or the side surface 13. The annular groove 4 is connected to the outside through the vent 5, allowing the air pressure in the annular groove 4 to be consistent with the external air pressure, thus not affecting the installation of components into the mounting holes 2 or the removal of the surface mount device from the components. When components are installed into the mounting holes 2, the gas inside the mounting holes 2 is compressed and discharged through the vent 5, without affecting the installation of components into the mounting holes 2. After soldering is completed, when the surface mount device is removed from the components, air is replenished into the annular groove 4 through the vent 5 to prevent the creation of a vacuum, which would affect the removal of the surface mount device.

[0042] In this embodiment of the invention, an annular groove 4 within each fixing hole 2 can be connected to a vent hole 5. The other end of the vent hole 5 is located on the side 13, which will not affect the setting of the adsorption part on the second surface 12. When the other end of the vent hole 5 is located on the second surface 12, it can be set close to the edge of the second surface 12, avoiding the center of the second surface 12, so that the middle part of the second surface 12 has enough space to set the adsorption part.

[0043] In some embodiments, see Figure 3 The breathable structure includes breathable holes 5 and connecting holes 6. At least one annular groove 4 within a fixing hole 2 connects to a second surface 12 and / or a side surface 13 through the breathable hole 5. The connecting hole 6 connects two annular grooves 4 within the fixing holes 2, so that all annular grooves 4 within the fixing holes 2 are directly or indirectly connected to the second surface 12 and / or the side surface 13 through the breathable holes 5. In this embodiment, some annular grooves 4 within the fixing holes 2 may connect to the outside through the breathable holes 5, and the remaining fixing holes 2 may be directly or indirectly connected to the fixing holes 2 with breathable holes 5 through the connecting holes 6. For example, the fixing body 1 has four fixing holes 2, one of which connects to the outside through the breathable hole 5, and the other three fixing holes 2 may be directly connected to the fixing holes 2 with breathable holes 5 through the connecting holes 6 respectively. Alternatively, one or two other fixing holes 2 may be directly connected to the fixing holes 2 with breathable holes 5 through the connecting holes 6, while the remaining fixing holes 2 are connected to the aforementioned fixing holes 2 with connecting holes 6 through the connecting holes 6.

[0044] In this embodiment of the invention, all the fixing holes 2 can be directly or indirectly connected through the connecting holes 6. Alternatively, only some of the fixing holes 2 can be directly or indirectly connected through the connecting holes 6.

[0045] In some embodiments, the venting structure includes a venting groove axially disposed on the sidewall of the mounting hole 2. One end of the venting groove is located within the annular groove 4, and the other end extends to the edge of the mounting hole 2. When the component is installed into the mounting hole 2, the gas inside the mounting hole 2 is compressed and discharged along the venting groove, without affecting the installation of the component into the mounting hole 2. After soldering is completed, when the surface mount device is removed from the component, air is replenished into the annular groove 4 through the venting groove to prevent a vacuum from being created, which would affect the removal of the surface mount device.

[0046] In an exemplary embodiment, the number of air vents on the sidewall of each fixing hole 2 can be one or more. When the number of air vents on the sidewall of each fixing hole 2 is multiple, the multiple air vents can be evenly distributed in the circumferential direction.

[0047] In some embodiments, see Figure 3 and Figure 5 The depths of the mounting holes 2 can be the same or different. The depth of the mounting hole 2 is the distance from the edge of the mounting hole 2 to the plane containing the top surface of the boss 3. When the depth of the mounting holes 2 is the same, it can be used for the placement of components with the same height. For example, when placing two or more Pogo pins 9 with the same height, the depth of the mounting holes 2 is the same to ensure that the overall height of the Pogo pins 9 is the same after SMT. When the depth of the mounting holes 2 is different, it can be used for the placement of components with different heights. For example, when placing two or more Pogo pins 9 with different heights, the depth of the mounting holes 2 is different to ensure that the Pogo pins 9 maintain their respective designed heights after SMT.

[0048] In some embodiments, see Figure 4 The mounting device of this embodiment further includes an adjusting piece 8, which is located on the top surface of the boss 3 and detachably connected to the boss 3 to adjust the depth of the fixing hole 2. The adjusting piece 8 allows the depth of the fixing hole 2 to be adjusted, thereby enabling the mounting device of this embodiment to be suitable for mounting components of different heights.

[0049] In this embodiment of the utility model, the connection method between the adjusting piece 8 and the boss 3 can include plugging or snapping.

[0050] In some embodiments, the adjusting piece 8 includes a body 81 and a connecting portion. The body 81 has opposing third and fourth surfaces. The connecting portion is connected to the body 81 and located on one side of the third surface. The adjusting piece 8 is connected to the boss 3 via the connecting portion. The adjusting piece 8 is detachably connected to the boss 3 via the connecting portion. The connecting portion can be connected to the boss 3, for example, by friction.

[0051] In some embodiments, see Figure 4The connecting part includes at least one connecting post 82, and the adjusting piece 8 is connected to the boss 3 through the connecting post 82.

[0052] In an exemplary embodiment, the connecting post 82 may be located on the third surface, and the number of connecting posts 82 may be one or more. In a specific embodiment, the connecting post 82 may be located in the middle of the third surface. For example, one connecting post 82 may be located in the middle of the third surface. The top surface of the boss 3 has a connecting hole 32 corresponding to the connecting post 82, and the connecting post 82 is interference-fitted with the connecting hole 32. When the adjusting piece 8 is connected to the boss 3, the connecting post 82 is inserted into the connecting hole 32 and connected to the boss 3 by friction.

[0053] In other exemplary embodiments, at least three connecting posts 82 are arranged circumferentially along the body 81, and at least three connecting posts 82 are connected to the peripheral surface of the boss 3 by friction. At least three connecting posts 82 are snapped onto the outer peripheral surface of the boss 3, facilitating the assembly and disassembly of the adjusting piece 8.

[0054] In some embodiments, the circumferential surface of the boss 3 has a connecting groove that mates with the connecting post 82, with the connecting post 82 located within the connecting groove. The connecting groove is arranged along the axial direction of the boss 3, and the connecting post 82 is located within the connecting groove, which can prevent the adjusting piece 8 from rotating relative to the boss 3.

[0055] In some embodiments, the connecting part may include a sleeve, which is disposed on the third side, and the adjusting piece 8 is sleeved on the boss 3 through the sleeve.

[0056] In this embodiment of the invention, the number of fixing holes 2 can be determined according to requirements. For example, when the fixing body 1 has two fixing holes 2, it can be used for mounting two components. When the fixing body 1 has four fixing holes 2, it can be used for mounting four components.

[0057] Components such as Pogo pin 9 can be fixed in the fixing hole 2 by interference fit.

[0058] The patch device of this embodiment can be made of high-temperature resistant plastic. High-temperature resistant plastic can withstand the high temperatures during the welding process and will not deform during welding. Furthermore, the plastic material will not scratch the components.

[0059] In some embodiments, after components such as Pogo pin 9 are installed into the fixing hole 2, the patch device with Pogo pin 9 fixed can be made into a tape and can be directly put into the line for patching, which greatly improves production efficiency and reduces production costs.

[0060] The mounting device of this utility model embodiment can be used to mount components onto flexible printed circuit boards (FPCs), rigid printed circuit boards (PCBs), and rigid-flex PCBs.
