Description

Technical Field

[0001] This utility model relates to the field of electronic device welding auxiliary technology, and in particular to a pin welding auxiliary device for a mini PC host. Background Technology

[0002] As electronic devices become smaller and lighter, mini PCs are increasingly widely used. Mini PCs have densely packed internal components and thin, closely spaced pins, requiring extremely high precision and stability when soldering these pins.

[0003] Traditional soldering aids have limited functionality. For example, when using tweezers alone to fix the pins, it is difficult to ensure the accuracy and stability of the pin position at the same time. Moreover, the operator's hand is prone to shaking, which can lead to soldering deviations. There is a lack of effective visual aids during the soldering process, making it difficult for the operator to clearly observe the soldering status of the pins, which can easily lead to problems such as cold solder joints and missing solder joints. To address these issues, we propose a pin soldering aid device for mini PC hosts. Utility Model Content

[0004] The purpose of this invention is to provide a pin soldering auxiliary device for a mini PC host, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pin soldering auxiliary device for a mini PC host, comprising an adjustment mechanism and an amplification mechanism disposed on its inner side. The adjustment mechanism includes a placement plate, with support frames fixedly installed on both upper ends of the placement plate. A mounting frame is fixedly installed on the upper end of the support frame. A first sliding groove is passed through the side of the mounting frame. A limit plate is fixedly installed on the outer surface of the mounting frame. A second sliding groove is formed on the surface of the mounting frame. A sliding rod is slidably connected inside the first sliding groove. The sliding rod is connected to a first limit bolt via a slider. A fixed rod is connected to the sliding rod via a sliding frame. An extension rod is slidably connected inside the fixed rod. Threaded rods are fixedly installed on both sides of the lower end of the extension rod. A strong spring and a limit nut are connected to the threaded rod via a clamp. Anti-slip silicone is fixedly installed on the inner side of the lower end of the clamp.

[0006] As a preferred embodiment, the second slide groove is connected to the first slide groove, the slider is fixedly installed on both sides of the upper end of the slide rod, the slider is slidably connected inside the second slide groove, and the first limiting bolt is threadedly connected inside the slider.

[0007] As a preferred embodiment, the slide is slidably connected to the outer wall of the slide rod, the slide is internally threaded with a second limiting bolt, the fixing rod is fixedly installed at the bottom of the slide, and the fixing rod is internally threaded with a third limiting bolt.

[0008] As a preferred embodiment, the clamp is slidably connected to the outer wall of the threaded rod, one end of the strong spring is fixedly connected to the clamp, the other end of the strong spring is fixedly installed on the side of the extension rod, and the limiting nut is threadedly connected to the outer wall of the threaded rod located outside the clamp.

[0009] As a preferred embodiment, the amplification mechanism includes a connecting frame, which is fixedly installed on the outer wall of the fixed rod. A fixed frame is fixedly installed on the front of the connecting frame, and a movable frame is sleeved on the outer wall of the fixed frame.

[0010] As a preferred embodiment, a rotating frame is sleeved on the outer wall of the fixed shaft, a high-definition camera is snapped onto the bottom of the rotating frame, and a focusing lens is sleeved on the lens of the high-definition camera.

[0011] The technical effects and advantages of this utility model are as follows: 1. Through the adjustment mechanism, the anti-slip silicone fixedly installed on the inner side of the lower end of the clamp can directly contact the pins of the mini PC host, increasing the friction between the clamp and the pins, preventing the pins from sliding due to external force during the soldering process, and ensuring that the pins are always in the preset soldering position. The strong spring can automatically adjust the clamping force according to the diameter of the pin. After the clamp is adjusted to the clamping position of the matching pin, the position of the clamp on the threaded rod is fixed by tightening the limit nut. At the same time, the clamping position can be changed in three-dimensional space by moving the slide bar, slide bracket and extension bar to adapt to the pin soldering in any position. 2. Through the magnification mechanism, the high-definition camera mounted at the bottom of the rotating frame, together with the focusing lens attached to the lens, can provide high-definition imaging of the delicate pins and soldering areas of the mini PC host. The focusing lens can flexibly adjust the magnification according to the pin size and soldering requirements, which can clearly magnify the fine structure of the pins and also fully present the overall state of the local soldering area. This solves the problem that it is difficult to distinguish the details of small pins when observed with the naked eye in the traditional way, and helps operators to discover potential problems such as pin deformation and insufficient solder, reducing soldering defects caused by blind spots.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 - Appendix Figure 4 A pin soldering auxiliary device for a mini PC host includes an adjustment mechanism 1 and an amplification mechanism 2 disposed inside it. The adjustment mechanism 1 includes a placement plate 101, with support frames 102 fixedly mounted on the upper ends of both sides of the placement plate 101. A mounting frame 103 is fixedly mounted on the upper end of the support frame 102. A first sliding groove 104 extends through the side of the mounting frame 103. A limit plate 105 is fixedly mounted on the outer surface of the mounting frame 103. A second sliding groove 106 is formed on the surface of the mounting frame 103. The slide rail 104 is internally connected to a slide rod 107. The slide rod 107 is connected to a first limiting bolt 109 via a slider 108. The slide rod 107 is connected to a fixing rod 112 via a slide frame 110. The fixing rod 112 is internally connected to an extension rod 114. Threaded rods 115 are fixedly installed on both sides of the lower end of the extension rod 114. The threaded rod 115 is connected to a strong spring 116 and a limiting nut 118 via a clamp 117. Anti-slip silicone 119 is fixedly installed on the inner side of the lower end of the clamp 117.

[0016] The mini PC host is supported by the placement plate 101, and the mounting brackets 102 on both sides support the mounting bracket 103, forming a stable equipment base. The first slide groove 104 on the mounting bracket 103 allows the slide rod 107 to slide. The slide rod 107 is connected to the fixed rod 112 through the slide frame 110. The extension rod 114 inside the fixed rod 112 is telescopic, forming a multi-dimensional adjustment chain, which can drive the clamp 117 at the lower end of the extension rod 114 to accurately align the pins at different positions of the host. The clamp 117 adapts to pins of different diameters through the strong spring 116, the anti-slip silicone 119 prevents slippage, and the limit nut 118 locks the clamping range to ensure that the pins do not shift during soldering.

[0017] The second slide groove 106 communicates with the first slide groove 104. The slider 108 is fixedly installed on both sides of the upper end of the slide rod 107. The slider 108 is slidably connected inside the second slide groove 106. The first limiting bolt 109 is threadedly connected inside the slider 108.

[0018] The second slide groove 106 communicates with the first slide groove 104, allowing the sliders 108 on both sides of the upper end of the slide rod 107 to slide within the second slide groove 106, thus linking with the movement of the slide rod 107 within the first slide groove 104 and preventing the slide rod 107 from tilting or shifting. At the same time, the first limiting bolt 109 is threaded into the slider 108. The operator only needs to tighten the first limiting bolt 109 to press against the limiting plate 105 to lock the position of the slide rod 107. Loosening it allows for continued sliding adjustment without the need for additional tools, making it suitable for scenarios where frequent adjustments to pin alignment are required during welding.

[0019] The slide 110 is slidably connected to the outer wall of the slide rod 107. The slide 110 is internally threaded with a second limiting bolt 111. The fixing rod 112 is fixedly installed at the bottom of the slide 110. The fixing rod 112 is internally threaded with a third limiting bolt 113.

[0020] The slide 110 can slide horizontally on the outer wall of the slide rod 107. With the second limiting bolt 111 inside the slide 110, tightening it can lock the slide 110, thereby driving the fixed rod 112 and the clamp 117 to adjust their positions. The extension rod 114 inside the fixed rod 112 can slide. The extension length is locked by the third limiting bolt 113 inside the fixed rod 112, so that the clamp 117 can cover the pins from the edge of the host to the deep inside, and can complete the full area clamping without moving the host.

[0021] The clip 117 is slidably connected to the outer wall of the threaded rod 115. One end of the strong spring 116 is fixedly connected to the clip 117, and the other end of the strong spring 116 is fixedly installed on the side of the extension rod 114. The limiting nut 118 is threadedly connected to the outer wall of the threaded rod 115 located outside the clip 117.

[0022] It can automatically adjust the clamping distance according to the pin diameter, avoiding the drawbacks of traditional methods; the limiting nut 118 on the outside of the threaded rod 115 can pre-adjust the maximum sliding range of the clamp 117 to prevent clamping problems caused by excessive or insufficient spring force; the anti-slip silicone 119 on the inner side of the lower end of the clamp 117 further increases the friction to prevent the pin from sliding due to solder melting or vibration during soldering.

[0023] Specifically, the anti-slip silicone 119 fixedly installed on the inner side of the lower end of the clip 117 can directly contact the pins of the mini PC host, increasing the friction between the clip 117 and the pins, preventing the pins from sliding due to external forces during the soldering process, and ensuring that the pins are always in the preset soldering position. The strong spring 116 can automatically adjust the clamping force according to the diameter of the pin. After the clip 117 is adjusted to the clamping position of the matching pin, the position of the clip 117 on the threaded rod 115 is fixed by tightening the limit nut 118. At the same time, the clamping position can be changed in three-dimensional space by moving the slide rod 107, the slide 110 and the extension rod 114 to adapt to the pin soldering in any position.

[0024] Please see the appendix Figure 1 and attached Figure 5 The amplification mechanism 2 includes a connecting frame 201, which is fixedly installed on the outer wall of the fixed rod 112. A fixed frame 202 is fixedly installed on the front of the connecting frame 201. A movable frame 203 is sleeved on the outer wall of the fixed frame 202. A fixed shaft 204 is fixedly installed on the inner bottom of the movable frame 203.

[0025] The design of the connecting frame 201 fixed to the outer wall of the fixed rod 112 enables the amplification mechanism 2 and the clamping component of the adjustment mechanism 1 to be linked. When the position of the clamp 117 is adjusted by the slide 110 and the extension rod 114, the connecting frame 201 will drive the fixed frame 202 and the moving frame 203 to move synchronously, ensuring that the observation center of the amplification mechanism 2 always follows the pin clamped by the clamp 117, avoiding misalignment between observation and clamping. At the same time, the moving frame 203 is sleeved on the outer wall of the fixed frame 202 and can slide and rotate along the length of the fixed frame 202, which can finely adjust the lateral position of the observation component and adapt to the observation needs of multiple adjacent pins in the same area.

[0026] A rotating frame 205 is sleeved on the outer wall of the fixed shaft 204. A high-definition camera 206 is snapped onto the bottom of the rotating frame 205. A focusing lens 207 is sleeved on the lens of the high-definition camera 206.

[0027] The rotating frame 205 can rotate 360 ​​degrees around the fixed axis 204, thereby adjusting the observation angle of the high-definition camera 206. For example, when welding vertically distributed pins, the camera can be rotated to a side view angle to clearly observe the solder climbing along the pins. When welding densely packed pins, it can be rotated to a 45-degree angle to avoid obstruction by adjacent pins. At the same time, the high-definition camera 206, together with the focusing lens 207, can magnify the details of the pins by 5-20 times, clearly showing whether the solder has formed a full solder joint, whether there are problems such as cold solder joints or missing solder joints, replacing the blurry observation of traditional naked eyes or ordinary magnifying glasses. Moreover, the high-definition camera 206 is clipped to the bottom of the rotating frame 205. If a malfunction occurs, it can be quickly disassembled and replaced without affecting the overall use of the equipment.

[0028] Specifically, the high-definition camera 206, which is snapped onto the bottom of the rotating bracket 205, together with the focusing lens 207 fitted onto the lens, can perform high-definition imaging of the delicate pins and soldering areas of the mini PC host. The focusing lens 207 can flexibly adjust the magnification according to the pin size and soldering requirements, which can clearly magnify the fine structure of the pins and also fully present the overall state of the local soldering area. This solves the problem that it is difficult to distinguish the details of small pins when observed with the naked eye in the traditional way, and helps operators to discover potential problems such as pin deformation and insufficient solder in time, reducing soldering defects caused by blind spots.

[0029] Working principle of this utility model: This utility model is a pin soldering auxiliary device for a mini PC host. First, the mini PC host to be soldered is placed stably on the placement plate 101. The placement position is adjusted according to the size of the host to ensure that the pin area to be soldered is directly below the clamp 117 of the adjustment mechanism 1, so as to avoid the support frame 102 from blocking the operating space.

[0030] Loosen the first limiting bolt 109 inside the slider 108, push the slide rod 107 to slide laterally along the first slide groove 104, and at the same time, the slider 108 slides synchronously in the communicating second slide groove 106. Loosen the second limiting bolt 111 inside the slide bracket 110, slide the slide bracket 110 laterally along the outer wall of the slide rod 107, and drive the fixing rod 112, extension rod 114 and clamp 117 to adjust synchronously until the clamp 117 is initially aligned with the target pin area of ​​the mini PC host, and tighten the first limiting bolt 109. Lock the position of the slide bar 107 with the positioning bolt 109, tighten the second limiting bolt 111 to fix the slide 110, loosen the third limiting bolt 113 inside the fixing rod 112, pull the extension rod 114 to slide along the inside of the fixing rod 112, adjust the distance between the clamp 117 and the edge of the host to ensure that the clamp 117 can accurately reach the target pin, tighten the third limiting bolt 113 to lock the extension rod 114, so that the anti-slip silicone 119 at the lower end of the clamp 117 is at the same level as the pin.

[0031] Pull the two clamps 117 outwards to slide them along the outer wall of the threaded rod 115 and stretch the strong spring 116, aligning the opening of the clamp 117 with the target pin; slowly release the clamp 117, the strong spring 116 rebounds and causes the clamp 117 to clamp the pin, and the anti-slip silicone 119 makes close contact with the pin to prevent slippage; check the clamping stability: gently push the pin to confirm that there is no looseness. If the clamping is too loose, the limiting nut 118 on the outer side of the threaded rod 115 can be turned inwards to reduce the sliding range of the clamp 117 and increase the clamping force; if the clamping is too tight, the limiting nut 118 can be turned outwards to ensure that the pin position is fixed and there is no deformation.

[0032] Since the connecting frame 201 is fixed to the outer wall of the fixed rod 112, the magnifying mechanism 2 moves synchronously when the adjusting mechanism 1 is adjusted. At this time, it is only necessary to slide the moving frame 203 along the outer wall of the fixed frame 202 to fine-tune the lateral position of the high-definition camera 206 so that the lens is directly facing the pin solder joint held by the clamp 117. Rotate the rotating frame 205, which is sleeved on the outer wall of the fixed shaft 204, to adjust the angle of the high-definition camera 206. For example, when welding horizontal pins, adjust to a top-down angle, and when welding vertical pins, adjust to a side-view angle to avoid obstruction during welding torch operation. Rotate the focusing lens 207 on the lens of the high-definition camera 206 to magnify the pin details by 5-20 times until the solder joint is clearly visible in the display screen, meeting the welding observation requirements.

[0033] The operator holds a soldering torch and aims it at the clearly visible solder joint area displayed by the high-definition camera 206. During the process, the operator observes the solder melting state and the fusion of the pins and pads in real time through the camera to avoid cold solder joints or missed solder joints. After completion, the mini PC host can be removed.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
