Description

Technical Field

[0001] The utility model relates to the technical field of welding tools, in particular to a manual welding auxiliary tool. Background Art

[0002] Manual soldering is widely used in electronics manufacturing and repair. It's ideal for product trials, small-batch production, and the manufacture of electronic products requiring high reliability. Furthermore, in specialized situations, such as repairing complex circuit boards, manual soldering remains an indispensable skill. During the soldering process, soldering errors can occur, damaging components. In these cases, desoldering is necessary. During desoldering, the soldering iron heats the pads, melting the solder in the vias and allowing the pins of the components to be removed.

[0003] However, after the pins of the circuit components are pulled out of the vias, the liquid solder will flow in the vias, causing the vias to be blocked again. Using a conventional solder sucker to absorb the solder has the problem of incomplete solder absorption, which causes the solidified solder in the vias to hinder the pins from being inserted into the vias, making it inconvenient to install subsequent replacement circuit components. Utility Model Content

[0004] In view of this, the present invention aims to provide a manual soldering auxiliary tool to improve the installation convenience of circuit components during the desoldering process.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A manual welding auxiliary tool, comprising:

[0007] Grip;

[0008] an assembly portion, detachably connected to the grip portion;

[0009] a placeholder, made of a non-stick solder material, connected to the assembly portion;

[0010] When the solder in the via hole of the pad is heated and melted, the placeholder can be inserted into the via hole, so that the solder solidifies to form a through hole with the same shape as the placeholder.

[0011] Furthermore, the gripping portion includes:

[0012] handle;

[0013] a grip threadedly connected to the handle;

[0014] One end of the assembly portion passes through the handle and is provided with the placeholder, and the handle and the handle jointly clamp the other end of the assembly portion.

[0015] Furthermore, an adjustment pad is sandwiched between the assembly portion and the handle.

[0016] Furthermore, the adjustment pad is made of nylon.

[0017] Furthermore, the assembly portion includes:

[0018] An assembly body, one end of which is provided with a first anti-rotation block embedded in the handle, and the other end of which passes through the handle;

[0019] An extension rod has one end which is interference-fitted with the assembly body and the other end which is detachably connected to the placeholder body.

[0020] Furthermore, the assembly portion includes a gland threadedly connected to the extension rod;

[0021] One end of the placeholder is embedded in the end of the extension rod away from the assembly body, and the other end passes through the pressure cover; the pressure cover and the extension rod jointly clamp the placeholder.

[0022] Furthermore, the placeholder is embedded in one end of the extension rod and is provided with a second anti-rotation block.

[0023] Furthermore, the end of the gland away from the extension rod is a prism.

[0024] Furthermore, the handle is covered with an anti-slip cover.

[0025] Furthermore, the handle is provided with anti-slip textures.

[0026] Furthermore, the circumferential outer side wall of the handle is concave to form a gripping groove.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] The manual soldering auxiliary tool described in the present invention, by providing a placeholder, can be inserted into the via to occupy the position when the solder in the via is heated and the pin is moved out of the via, so that after the subsequent solder solidifies, a through hole is formed, so that the pin of the replaced circuit component can be inserted into the via, and the residual solder does not affect the insertion of the pin, thereby improving the installation efficiency of subsequent circuit components; at the same time, the assembly part and the holding part are detachably connected, and when the non-holding part of the manual soldering auxiliary tool is damaged, only the damaged unit can be replaced, thereby improving the utilization rate of parts; the placeholder is made of non-stick solder material, which can prevent the adhesion of solder.

[0029] Secondly, the handle and grip are provided, and the assembly portion extends through the grip, allowing for quick assembly and disassembly of the assembly portion while maintaining a secure connection between the assembly portion and the grip. An adjustment pad is provided between the assembly portion and the handle to ensure that once the handle and grip are screwed into place, the adjustment pad and assembly portion are clamped securely, preventing the assembly from loosening. The adjustment pad is made of nylon, providing excellent compressive strength and a smooth surface. This reduces friction when the adjustment pad abuts the assembly portion and handle, resulting in less resistance when the grip is further tightened, facilitating installation and use.

[0030] Furthermore, the placeholder is detachable and can be installed. When operating on vias of different sizes, it is only necessary to replace the placeholder to adapt. The extension rod can increase the length of the front end of the manual soldering auxiliary tool, which is more convenient for the operator to use. The assembly is provided with a rotation stop block, which can prevent relative rotation with the handle, so as to facilitate the use of the manual soldering auxiliary tool. A second rotation stop block is provided at one end of the extension rod where the placeholder is embedded. When the grip is rotated during the use of the manual soldering auxiliary tool, the placeholder can rotate synchronously, making it easy to separate the placeholder from the solder. The placeholder is pressed tightly into the extension rod using a pressure cap. After the solder in the via solidifies, the placeholder will not fall off when it is pulled out. The end of the pressure cap away from the extension rod is set as a prism, which can be easily screwed with a wrench or other tool, making it easy to replace and install the placeholder.

[0031] In addition, a non-slip cover on the handle makes the grip more comfortable for the operator, providing greater friction and preventing slippage during use, thereby improving operational flexibility. The anti-slip texture on the handle increases friction with the operator's hand, enhancing the feel and flexibility of use. Gripping grooves on the outer circumferential wall of the handle facilitate the operator's use of the manual welding auxiliary tool in three different grip positions: forward grip, reverse grip, and pen grip, providing flexibility and adaptability.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0049] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0050] This embodiment relates to a manual soldering auxiliary tool to improve the installation convenience of circuit components during the desoldering process.

[0051] Structurally, the manual soldering aid tool in this embodiment comprises a gripping portion, an assembly portion, and a placeholder. The assembly portion is detachably connected to the gripping portion. The placeholder, made of aluminum alloy, is connected to the assembly portion. Once the solder in the via hole of the pad is heated and melted, the placeholder can be inserted into the via hole, allowing the solder to solidify and form a through-hole with the same shape as the placeholder.

[0052] As configured above, the manual soldering aid tool of this embodiment, by providing a placeholder, can be inserted into the via to occupy a position while the solder in the via is heated and the pin is removed from the via. This allows the solder to solidify, forming a through-hole, facilitating the insertion of the replaced circuit component pin into the via. Residual solder does not interfere with the insertion of the pin. Furthermore, the assembly portion and the grip portion are detachably connected, allowing only the damaged unit to be replaced if the non-gripping portion of the manual soldering aid tool is damaged, thereby improving component utilization. The placeholder is made of a non-stick solder material to prevent solder from adhering.

[0053] Based on the above overall introduction, refer to Figures 1 to 5 As shown, specifically, the material of the placeholder 3 can be aluminum alloy or stainless steel. Aluminum alloy reacts with oxygen in the air to form a dense oxide film on the surface, which affects the wettability and fluidity of the solder. Therefore, aluminum is not easy to stick to the solder. The surface of the stainless steel material has a dense chromium oxide layer, which prevents the solder from contacting the stainless steel body. In addition, the melting point of stainless steel is much higher than that of the solder. This makes it impossible for the solder to reach a high enough temperature to melt and wet the stainless steel surface during the soldering process, so the solder does not stick to the solder. The portion of the placeholder 3 inserted into the via hole of this embodiment is cylindrical, which can leave a through circular hole at the via hole. Of course, the portion of the placeholder 3 inserted into the via hole can also be other shapes, as long as the through hole left can allow the pins of the replaced circuit components to be inserted normally.

[0054] Among them, as for the structure of the gripping portion 1, the gripping portion 1 of this embodiment includes a handle 101 and a grip 102. The handle 101 and the grip 102 are both cylindrical bodies. The grip 102 is connected to the handle 101 by a thread and is coaxially detachably connected to the handle 101. One end of the assembly portion 2 passes through the grip 102 and is provided with a placeholder 3. The handle 101 and the grip 102 jointly clamp the other end of the assembly portion 2. The assembly portion 2 is also a cylindrical body and coaxially passes through the grip 102. Providing the handle 101 and the grip 102 and passing the assembly portion 2 through the grip 102 can quickly assemble and disassemble the assembly portion 2, and the connection between the assembly portion 2 and the gripping portion 1 is also relatively firm. The gripping portion 1 is made of carbon steel, which is easy to process and durable, and has a low manufacturing cost.

[0055] Secondly, to ensure that the handle 101 and the grip 102 firmly clamp the assembly part 2, an adjustment pad 4 is provided between the assembly part 2 and the handle 101. Providing the adjustment pad 4 between the assembly part 2 and the handle 101 ensures that after the handle 101 and the grip 102 are screwed into place, the adjustment pad 4 and the assembly part 2 are clamped tightly, preventing the assembly part 2 from loosening.

[0056] Specifically, the adjustment pad 4 is made of nylon. Using nylon provides the adjustment pad 4 with superior compressive strength and a certain degree of elasticity, thereby preventing loosening between the handle 101 and the grip 102. Furthermore, the nylon surface is relatively smooth, resulting in low friction when the adjustment pad 4 abuts the assembly portion 2 and the handle 101. This reduces resistance when the grip 102 is further tightened, facilitating installation and use. In this embodiment, the adjustment pad 4 is a circular gasket, making assembly easier. Of course, the adjustment pad 4 can also be configured as a gasket of other shapes without affecting its functionality.

[0057] As for the structure of the assembly part 2, the assembly part 2 of this embodiment includes: an assembly body 201 and an extension rod 202. A first anti-rotation block 2011 embedded in the handle 102 is provided at one end of the assembly body 201, and the other end passes through the handle 102. One end of the extension rod 202 is interference-fitted with the assembly body 201, and the other end is detachably connected to the placeholder 3. The placeholder 3 is detachably installed, and when operating on vias of different sizes, only the placeholder 3 can be replaced to adapt. The provision of the extension rod 202 can increase the length of the front end of the manual welding auxiliary tool, which is more convenient for the operator when using it. The assembly body 201 is provided with a anti-rotation block, which can rotate relative to the handle 102, so as to facilitate the use of the manual welding auxiliary tool.

[0058] Specifically, the first anti-rotation block 2011 is in the shape of a hexagonal prism, and the handle 102 is provided with a hexagonal slot adapted to the first anti-rotation block 2011, so that the first anti-rotation block 2011 and the handle 102 do not rotate relative to each other. It is understandable that the first anti-rotation block 2011 can also be other polygonal cross-section cylinders or arcuate cross-section cylinders, as long as they are not rotating bodies. Regarding the materials of the assembly 201 and the extension rod 202, the assembly 201 of this embodiment is made of carbon steel, which is easy to process, durable, and has a low manufacturing cost. The extension rod 202 is made of nickel-chromium alloy, which has good wear resistance and high hardness, strong corrosion resistance, and a long service life.

[0059] Furthermore, the assembly portion 2 includes a gland 203 that is threadedly connected to the extension rod 202. One end of the placeholder 3 is embedded in the end of the extension rod 202 away from the assembly body 201, and the other end passes through the gland 203. The gland 203 and the extension rod 202 together clamp the placeholder 3. The gland 203 presses the placeholder 3 tightly against the extension rod 202. After the solder in the via solidifies, the placeholder 3 will not fall out when it is removed.

[0060] In addition, a second anti-rotation block 301 is provided at one end of the placeholder 3 embedded in the extension rod 202. By providing the second anti-rotation block 301 at one end of the placeholder 3 embedded in the extension rod 202, the placeholder 3 can be synchronously rotated when the gripping portion 1 is rotated during the use of the manual welding auxiliary tool, making it easier to separate the placeholder 3 from the solder. Preferably, the end of the pressure cap 203 away from the extension rod 202 is a prism. Setting the end of the pressure cap 203 away from the extension rod 202 as a prism makes it easy to screw the pressure cap 203 using tools such as a wrench, thereby facilitating the replacement and installation of the placeholder 3. In this embodiment, the end of the pressure cap 203 away from the extension rod 202 is a hexagonal prism, and the pressure cap 203 can be screwed using a conventional wrench or pliers.

[0061] In order to improve the operational flexibility of the grip portion 1, the grip 102 is covered with an anti-slip cover 1021. Covering the grip 102 with the anti-slip cover 1021 can make the operator more comfortable when holding the grip 102, and has greater friction and is not easy to slip during use, thereby improving operational flexibility. The anti-slip cover 1021 can be made of rubber, silicone, or foamed polyurethane, etc. In this embodiment, the anti-slip cover 1021 is made of silicone. At the same time, the handle 101 is provided with anti-slip lines 1011. Providing the anti-slip lines 1011 on the handle 101 can increase the friction with the operator's hand, enhance the feel of use and operational flexibility. In this embodiment, the anti-slip lines 1011 are spiral lines, which have a good anti-slip effect and are more beautiful. In addition, the circumferential outer wall of the grip 102 is concave to form a gripping groove 1021. A gripping groove 1021 is provided on the circumferential outer wall of the gripping handle 102, so that the operator can adopt three gripping postures of forward grip, reverse grip and pen grip for the manual welding auxiliary tool, which is flexible and changeable during use.

[0062] The manual soldering aid of this embodiment is designed to install a placeholder 3 corresponding to the size of the via. During soldering or repair, after the pin is pulled out of the via, the via is re-blocked by the flowing solder. Heat the pad with a soldering iron, then insert the placeholder 3 into the via. Remove the iron and wait 1 to 2 seconds for the solder to solidify. Because the placeholder 3 is non-sticky, removing it leaves a through-hole in the via, facilitating subsequent insertion of the pins of circuit components.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
