[0025] In existing technologies, the process of soldering multiple enameled wires to a circuit board for electronic products such as Bluetooth headsets usually requires two soldering fixtures, which are stacked on top of each other to achieve the soldering. The soldering process and the soldering fixtures are complex and the soldering efficiency is low.

[0026] This utility model proposes a welding fixture.

[0027] Please see Figures 1 to 6 In one embodiment of this utility model, the welding fixture includes: a base 300, a first positioning module 100, and a second positioning module 200. The first positioning module 100 is disposed on the base 300 and has a first support portion 111 for placing a first product. The second positioning module 200 is located on one side of the first positioning module 100 and has a second support portion 211 for placing a second product. The second product has a line to be welded. The second positioning module 200 is slidably connected to the base 300 and has a welding position close to the first positioning module 100. At the welding position, the line to be welded extends to the first positioning module 100 and is used for welding with the first product.

[0028] In this embodiment, the first positioning module 100 is fixedly mounted on the base 300, and the second positioning module 200 is slidably connected to the base 300 and slides closer to or further away from the first positioning module 100. The first support portion 111 can be a protrusion structure, a groove structure, or other structures; this embodiment is not limited as long as it can fix the first product. In specific implementation, the appropriate first support portion 111 is selected based on the specific structure of the first product. Similarly, the second support portion 211 can be a protrusion structure, a groove structure, or other structures. Referring to the first support portion 111, the appropriate second support portion 211 is selected based on the specific structure of the second product, which will not be described in detail here. In this embodiment, the first support portion 111 and / or the second support portion 211 are configured as grooves, which provide good positioning for the first and second products.

[0029] In one embodiment, the first product is configured as a circuit board, such as an FPC board, and the first support portion 111 is configured as a groove. The second product is configured as an electronic product, such as a Bluetooth headset, with wires to be soldered, such as enameled wires. The circuit board and the electronic product are fixed using a soldering fixture. In the specific implementation process, a person or a robot places the circuit board on the first support portion 111 and the electronic product on the second support portion 211. The second positioning module 200 is driven to approach the first positioning module 100 to the soldering position, and the wires to be soldered are arranged and extended to the first support portion 111. The wires to be soldered are soldered onto the circuit board using a pulse soldering device, which improves the efficiency and quality of the soldering.

[0030] This utility model's technical solution employs a first positioning module 100 on a base 300 to fix a first product, and a second positioning module 200 slidably positioned to fix a second product. The first product is fixed to the first support portion 111 of the first positioning module 100, and the second product is fixed to the second support portion 211 of the second positioning module 200. When the second positioning module 200 slides along the base 300 towards the first positioning module 100, the welding line of the second product extends to the first positioning module 100 and is used for welding with the first product. Thus, by using a welding fixture that slides through the second positioning module 200 and approaches the first positioning module 100, welding of the welding line of the second product to the first product can be achieved, simplifying the welding process and improving welding efficiency.

[0031] refer to Figure 2 As shown, in one embodiment, the first positioning module 100 includes a first fixing base 110 and a first cable management base 120 disposed on the first fixing base 110. A first bearing portion 111 is disposed on the first fixing base 110, and the first cable management base 120 is disposed on the side of the first bearing portion 111 away from the second positioning module 200. The first cable management base 120 is provided with a plurality of first slots 121, which are spaced apart. Each wire to be soldered is snapped into the corresponding first slot 121.

[0032] The first fixing seat 110 is fixed to the base 300 by bolts or other connecting parts. The first cable management seat 120 is fixed to the first fixing seat 110 and is located on the side of the first bearing part 111 away from the first positioning module 100 to facilitate the arrangement of the wires to be welded. The part of the wire to be welded corresponding to the first bearing part 111 corresponds to the position of the first product that needs to be welded, so as to facilitate welding. Specifically, there are multiple wires to be welded, and multiple wires to be welded correspond to multiple first slots 121. According to the welding requirements of the first product, the wires to be welded are fixedly clamped in the first slots 121 for positioning and are close to the first product. The wires to be welded are then welded to the first product by welding equipment. In the specific implementation process, the first fixing seat 110 is provided with a first mounting groove, the first cable management seat 120 is partially located in the first mounting groove, the first fixing seat 110 is also connected with a clamping block, the clamping block is installed on the first fixing seat 110 by screws and presses the first cable management seat 120 into the first mounting groove. Of course, it can be understood that the first cable management seat 120 also has a portion extending to the outside of the first mounting seat and has a first slot 121 for fixing the wire to be soldered.

[0033] Furthermore, a second cable management seat 130 is provided on the side of the bearing unit near the second positioning module 200. The second cable management seat 130 is provided with a second slot 131, and the first slot 121 is provided in correspondence with the second slot 131.

[0034] In this embodiment, the first cable management seat 120 and the second cable management seat 130 are located on opposite sides of the first support portion 111, respectively, to cooperate in aligning the wires to be welded more accurately with the welding position of the first product, thereby improving welding accuracy and welding effect. In specific implementation, the first fixing seat 110 has a second mounting groove, and the second cable management seat 130 is engaged within the second mounting groove. The first slot 121 and the second slot 131 correspond and cooperate to organize the wires to be welded.

[0035] Furthermore, the first fixing base 110 is provided with a baffle 140, which is located on the side of the second cable management base 130 opposite to the first cable management base 120. The baffle 140 has an avoidance slot 141, which is correspondingly provided with the second slot 131. In the specific implementation process, the baffle 140 is located on one side of the second cable management base 130, and the width of the avoidance slot 141 is greater than the width of the second slot 131. That is, compared with the second slot 131, the avoidance slot 141 has a larger accommodating space to avoid other parts of the wire to be welded, so as to facilitate the welding of the wire to be welded. In addition, the setting of the baffle 140 can also improve the support strength of the second cable management slot and prevent skewing that would affect the welding accuracy.

[0036] In this embodiment, the first cable management holder 120 and / or the second cable management holder 130 are made of flexible material. It should be noted that the components to be soldered need to be immersed in tin before soldering to ensure the soldering effect. The flexible material of the first cable management holder 120 and the second cable management holder 130 can adapt to different diameters of the wires to be soldered by deformation, thus overcoming the problem of the wires not being able to be held in place due to their large diameter after tinning.

[0037] refer to Figure 3 As shown, in one embodiment, the first positioning module 100 further includes a first cover plate 150 and a first fastener 160. The first cover plate 150 is rotatably disposed on the first fixed seat 110. The first cover plate 150 and / or the first fixed seat 110 are provided with the first fastener 160. The first cover plate 150 flips over and presses onto the first product, and provides clamping force through the first fastener 160.

[0038] Specifically, the first cover plate 150 and the first fixed seat 110 are rotatable via a pivot, and one side of the first cover plate 150 is connected to the pivot, allowing the first cover plate 150 to be flipped. The first fastener 160 can be a snap-fit ​​or an adsorption device, etc. When the first cover plate 150 is flipped and placed on the first fixed seat 110, it is fixed by the first fastener 160, so that the first cover plate 150 can press the first product against the first support portion 111.

[0039] Open the first cover plate 150 and place the first product on the first support portion 111. Flip the first cover plate 150 over the first fixing seat 110 and press it firmly to fix the first product, preventing it from shifting. In specific implementation, the first cover plate 150 is made of magnetic metal, and the first fastener 160 is a magnet. The magnet is fixed to the first fixing seat 110. When the first cover plate 150 is flipped over and placed over the first fixing seat 110, the magnet is used to attract the first cover plate 150. In addition, the first fastener 160 is configured as a magnet. When both the first cover plate 150 and the first fixing seat 110 are equipped with the first fastener 160, the two first fasteners 160 attract each other.

[0040] It should be noted that the first cover plate 150 is provided with a pressing part 151, and the first cable management seat 120 is provided with a relief groove 122. The pressing part 151 passes through the relief groove 122 and extends to the first bearing part 111, pressing the first product against the first bearing part 111. In this embodiment, the pressing part 151 is integrally formed with the first cover plate 150 and is either a protruding elongated strip or a structure adapted to fit the first product; no limitation is made here. The pressing part 151 extends to the first bearing part 111 through the relief groove 122 of the first cable management seat 120, pressing against the position of the first product where welding is not required, so as to avoid affecting the welding process, thereby fixing the first product and preventing movement that would affect welding accuracy.

[0041] In one embodiment, the second positioning module 200 includes a second fixed base 210, a second cover plate 220, and a second fastener 230. A second bearing portion 211 is disposed on the second fixed base 210, and the second cover plate 220 is rotatably disposed on the second fixed base 210. The second fixed base 210 and / or the second cover plate 220 are provided with the second fastener 230, and the second cover plate 220 extends at least partially to the second bearing portion 211 for pressing the second product. The second fastener 230 provides the second cover plate 220 with a pressing force to press the second product.

[0042] It should be noted that the second fixing seat 210 is divided into two mutually fixed parts. One part is used to set the second bearing part 211 to fix the product. The material and surface process of this part are set according to the product requirements to avoid wear on the product. The other part is slidably connected to the base 300 so that the second positioning module 200 can move closer to or further away from the first positioning module 100.

[0043] In this embodiment, the second cover plate 220 is rotatably connected to the second fixing seat 210 and can be flipped. The second cover plate 220 is rotatably connected to the second fixing seat 210 via a rotating shaft. The second fastener 230 can be a structure such as a snap-fit ​​or an adsorption component. When the second cover plate 220 is flipped over and placed on the second fixing seat 210, it is fixed by the second fastener 230, so that the second cover plate 220 can press the second product against the second support portion 211.

[0044] In the specific implementation process, the second cover plate 220 is flipped open, the second product is placed on the second support portion 211, and the second cover plate 220 is flipped open again to cover the second fixing seat 210. The second cover plate 220 at least partially corresponds to the second support portion 211 to press and fix the second product. The second fastener 230 can be a magnet, and the second cover plate 220 and the second fastener 230 are fastened by magnetic attraction. In the specific implementation process, in order to ensure the stability of the second product, both the second cover plate 220 and the second fixing seat 210 are provided with second fasteners 230. The two sets of second fasteners 230 attract each other, and furthermore, multiple second fasteners 230 are provided, and they are attracted one-to-one, so that the second cover plate 220 presses the second product.

[0045] In one embodiment, the second cover plate 220 is provided with a limiting post 221. At the welding position, the limiting post 221 is used to limit the displacement of the second product to avoid interference with the welding process. It should be noted that, depending on the actual situation of the second product, there may be other moving parts that affect the welding process. Therefore, in this embodiment, the limiting post 221 is provided on the second cover plate 220, and the moving parts of the second product are arranged around the limiting post 221 to limit their displacement, thereby avoiding interference with the welding process.

[0046] To improve welding efficiency, multiple first and second products can be welded simultaneously. In specific implementation, the second fixing base 210 is provided with multiple second bearing portions 211 and multiple second cover plates 220. The multiple second bearing portions 211 are spaced apart, and each second bearing portion 211 corresponds to a second cover plate 220. Multiple second bearing portions 211 are arranged sequentially on the second fixing base 210, and multiple second cover plates 220 are correspondingly provided. In one embodiment, multiple first bearing portions 111 are provided on the first fixing base 110, and each first bearing portion 111 corresponds to one first product, or multiple first products are placed on the first bearing portions 111, thereby enabling welding of multiple first and second products. In another embodiment, multiple first positioning modules 100 are provided, spaced apart, and corresponding to the second bearing portions 211. Specifically, the first positioning modules 100 cooperate with the second bearing portions 211 to simultaneously achieve welding of multiple first and second products.

[0047] Based on the above, the second positioning module 200 also includes a connecting plate 240. Among the two adjacent second cover plates 220, one is connected to the connecting plate 240, and the other has a connecting groove 222. The connecting plate 240 extends into the connecting groove 222 and is movably connected to the connecting groove 222. The connecting groove 222 is located on the side of the second cover plate 220 facing the second fixed seat 210. The connecting plate 240 and the connecting groove 222 are arranged in sequence.

[0048] In this embodiment, multiple second cover plates 220 are spaced apart and arranged side by side. One second cover plate 220 is connected to one end of a connecting plate 240, and the other end of the connecting plate 240 is movably connected to the adjacent second cover plate 220. Specifically, a connecting groove 222 is formed on the side of the second cover plate 220 facing the second fixing seat 210 to accommodate the connecting plate 240 and ensure that the second cover plate 220 presses against the second product. In this way, multiple second cover plates 220 are connected by multiple connecting plates 240. (Refer to...) Figure 1 As shown, when the second cover 220 is closed, the open second cover 220 can be flipped and closed individually from left to right. When the second cover 220 is opened, the leftmost second cover 220 can be flipped and opened simultaneously by the connecting plate 240, thereby improving efficiency. Of course, the second cover 220 can be opened sequentially from right to left.

[0049] In one embodiment, the second positioning module 200 and the base 300 slide together via a slide rail 310 and a slider. Specifically, the base 300 is provided with a slide groove, and one of the second fixing seat 210 and the base 300 is provided with a slide rail 310, while the other is provided with a slider that slides along the slide rail 310, so that the second fixing seat 210 slides within the slide groove via the slide rail 310 and the slider.

[0050] The second positioning module 200 slides along the base 300. In this embodiment, in order to ensure the stability of the second fixed seat 210, two parallel slide rails 310 are provided on the base 300. Correspondingly, two sets of sliders are provided at the bottom of the second fixed seat 210 and slide along the slide rails 310.

[0051] In order to achieve rapid and stable positioning of the second positioning module 200 as it slides closer to or away from the first positioning module 100, in one embodiment, the first positioning module 100 and / or the second positioning module 200 are provided with a third fastener 400, and at the welding position, the first positioning module 100 and the second positioning module 200 are fastened together by the third fastener 400.

[0052] refer to Figure 4 As shown, in the specific implementation, the third fastener 400 is disposed on the sidewall opposite to the first positioning module 100 of the second positioning module 200. Specifically, one set of third fasteners 400 is disposed on the sidewall of the second fixing seat 210, and another set of third fasteners 400 is disposed on the sidewall of the first fixing seat 110. The two sets of third fasteners 400 attract each other. Thus, when the second positioning module 200 slides to the welding position, the third fasteners 400 attract and fix the first fixing seat 110 and the second fixing seat 210, making them relatively stable, thereby improving efficiency and stability. In the specific implementation, the third fastener 400 is configured as a magnet block.

[0053] refer to Figure 5 and Figure 6 As shown, the second positioning module 200 and / or the base 300 are further provided with a fourth fastener 500. The second positioning module 200 also has a material transfer position away from the first positioning module 100. At the material transfer position, the second positioning module 200 and the base 300 are connected by the fourth fastener 500. At the material transfer position, the second product is also placed on the second support part 211.

[0054] Specifically, the second product is placed or removed when the second positioning module 200 is away from the first positioning module 100. One side of the second positioning module 200 is also fixed to one side of the base 300 by a fourth fastener 500 to position the second positioning module 200. A set of fourth fasteners 500 is provided on both the side wall of the second fixing seat 210 away from the first fixing seat 110 and the side wall of the base 300. The two sets of fourth fasteners 500 are mutually attracted and fixed. In practice, the fourth fasteners 500 are magnets.
