[0002] In existing technologies, welding between connectors and wire conductors typically involves a combination of a sub-carrier and a mother carrier. Specifically, the sub-carrier performs laser pulling, cutting, and soldering of the conductor, while the mother carrier positions the connector; then, the sub-carrier is assembled into the mother carrier for welding. This approach requires a combination of sub- and mother carriers, which is problematic in several ways. Firstly, the carriers are complex and heavy, increasing operator fatigue. Secondly, the cumbersome operation steps lead to low efficiency. Furthermore, the multiple positioning operations introduce errors, resulting in poor welding precision.

[0003] Therefore, a welding fixture is urgently needed to solve the above problems. Utility Model Content

[0011] As a preferred embodiment of the welding fixture, the first support platform and / or the second support platform are provided with a clearance notch on the side that is close to each other, so as to form a welding through hole between the second support platform and the first support platform. The welding through hole penetrates the base plate, and the welding position corresponds to the welding through hole.

[0012] As a preferred embodiment of the welding fixture, the welding wire positioning mechanism includes a first welding wire positioning part and / or a second welding wire positioning part, wherein the first welding wire positioning part is configured to fix a first welding wire, and the second welding wire positioning part is configured to fix a second welding wire.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-4 As shown, this embodiment provides a welding fixture, which includes a base plate 100 and a first support platform 200, a second support platform 300, and a welding wire positioning mechanism disposed on the base plate 100. One of the first support platform 200 and the second support platform 300 is slidably disposed on the base plate 100, and one of them is configured to position a first workpiece 1 to be welded and the other is configured to position a second workpiece 2 to be welded. When one of the first support platform 200 and the second support platform 300 slides to the welding position, the part to be welded of the first workpiece 1 and the part to be welded of the second workpiece 2 are in contact with each other. The welding wire positioning mechanism is configured to fix the welding wire at the welding position.

[0037] By setting a base plate 100 for mounting the first support platform 200 and the second support platform 300, the integration of the welding fixture is improved, while the structure of the welding fixture is simplified. Of the first support platform 200 and the second support platform 300, one is used to position the first workpiece 1 to be welded, and the other is used to position the second workpiece 2 to be welded; one is fixedly mounted on the base plate 100, and the other is slidably mounted on the base plate 100. This allows the part to be welded on the second workpiece 2 to be welded to align with the part to be welded on the first workpiece 1 when one of the support platforms slides to the welding position, facilitating subsequent welding operations. The above-mentioned welding fixture only needs to position the first workpiece 1 and the second workpiece 2 separately, and then move one of the support platforms to achieve contact between the parts to be welded, reducing the number of positioning operations and thus improving positioning accuracy, while also making operation more convenient. In addition, the welding fixture is also equipped with a welding wire positioning mechanism, which is used to fix the welding wire at the welding position, improving the stability of the welding wire during welding and thus ensuring welding quality.

[0038] For example, the first support platform 200 is fixedly disposed on the base plate 100, and simultaneously positions the first workpiece 1 to be welded; the second support platform 300 is slidably disposed on the base plate 100, and simultaneously positions the second workpiece 2 to be welded.

[0039] In this embodiment, a clearance notch 310 is provided on the side of the first support platform 200 and / or the second support platform 300 that are close to each other, so as to form a welding through hole 101 between the second support platform 300 and the first support platform 200. The welding through hole 101 penetrates the base plate 100, and the welding position corresponds to the welding through hole 101. This arrangement enables the welding fixture to perform double-sided welding operations without repositioning the workpiece to be welded, which not only simplifies the welding process but also avoids the problem of low accuracy caused by repeated positioning, resulting in higher welding efficiency and better welding effect.

[0040] Specifically, the welding wire positioning mechanism includes a first welding wire positioning part and / or a second welding wire positioning part. In some embodiments, welding is only required on one side (e.g., the front or the back), and the welding wire positioning mechanism can be either the first welding wire positioning part or the second welding wire positioning part. In this embodiment, double-sided welding is required, and the welding wire positioning mechanism includes a first welding wire positioning part and a second welding wire positioning part. The first welding wire positioning part is configured to fix the first welding wire 31, and the second welding wire positioning part is configured to fix the second welding wire 32. The first welding wire 31 and the second welding wire 32 are used to provide solder to both sides of the first workpiece 1 and the second workpiece 2 to be welded, respectively. The first welding wire positioning part and the second welding wire positioning part can be respectively configured as holes for the first welding wire 31 and the second welding wire 32 to pass through, thereby achieving the positioning of the first welding wire 31 and the second welding wire 32 in one operation, and thus ensuring that the welding wire accurately corresponds to the welding position.

[0041] In this embodiment, the base plate 100 is detachably connected to a first cover plate 270 and / or a second cover plate 280, which can be configured according to actual needs. In this embodiment, the base plate 100 is detachably connected to a first cover plate 270 and a second cover plate 280, wherein the first cover plate 270 is configured to restrict the welding portion of the first weldable part 1 and / or the welding portion of the second weldable part 2 to ensure that the two welding portions do not move during welding. It is worth noting that when both sides of the first weldable part 1 and the second weldable part 2 need to be welded, two second cover plates 280 are provided. One second cover plate 280 is provided with a first welding wire crimping groove 222, which is configured to press against the first welding wire 31. The other second cover plate 280 is provided with a second welding wire crimping groove 250, which is configured to press against the second welding wire 32 to ensure that the welding wire does not move during welding.

[0042] For example, the first component to be soldered, 1, is a wire conductor, one end of which has multiple exposed wires spaced apart, and the spacing direction of the multiple wires is perpendicular to the extension direction of the wire conductor. The exposed multiple wires serve as the soldering positions of the wire conductor. The second component to be soldered, 2, is a connector, one end of which has a circuit board, which serves as the soldering position of the connector. The wire body needs to be soldered to the connector at a perpendicular angle to form the product.

[0043] Preferably, when welding is required on both sides of the first component 1 and the second component 2, two first cover plates 270 are provided. One first cover plate 270 is provided with a first wire positioning part 221, which is configured to press against the wire on one side of the first component 1. The other first cover plate 270 is provided with a second wire positioning part 240, which is configured to press against the wire on the other side of the first component 1, so as to ensure that the wire of the first component 1 does not move during welding. By positioning the wires individually, the problem of weld point misalignment can be effectively reduced.

[0044] Specifically, the first support platform 200 is provided with a first positioning structure 210, and the second support platform 300 is provided with a second positioning structure 320, so as to realize the positioning of the first workpiece 1 to be welded and the second workpiece 2 to be welded.

[0045] Optionally, the first positioning structure 210 includes at least three first positioning surfaces 211 that are angled together. These three first positioning surfaces 211 can abut against three sides of the first workpiece 1 to be welded, thereby positioning the first workpiece 1. For example, the first positioning structure 210 is configured as a first positioning groove, extending along a first direction and having its end connected to the welding through hole 101. The cross-sectional shape of the first positioning groove is the same as that of the first workpiece 1 to be welded, and the groove depth is adapted to the thickness of the first workpiece 1 to be welded. That is, the first positioning structure 210 can independently position the first workpiece 1 to be welded in three-dimensional space. Similarly, the second positioning structure 320 includes at least three second positioning surfaces 321 that are angled together. These three second positioning surfaces 321 can abut against three sides of the second workpiece 2 to be welded, thereby positioning the second workpiece 2. For example, the second positioning structure 320 is configured as a second positioning groove, extending along a second direction and having one end connected to the welding through hole 101 along the first direction. The cross-sectional shape of the second positioning groove is the same as that of the second part to be welded 2, and the groove depth is adapted to the thickness of the second part to be welded 2. That is, the second positioning structure 320 can independently achieve the positioning of the second part to be welded 2 in three-dimensional space. The first direction is... Figure 1 The middle X direction, the second direction is Figure 1 In the Y direction, the second direction is set perpendicular to the first direction.

[0046] Preferably, in order to improve the stability of the first workpiece to be welded 1 within the first positioning structure 210, the first support platform 200 is provided with a third cover plate 260 that flips relative to the first positioning structure 210. The third cover plate 260 can stably place the first workpiece to be welded 1 within the first positioning structure 210 after positioning, effectively avoiding the problem of incomplete welding caused by the first workpiece to be welded 1 not being pressed tightly, thereby improving the welding accuracy.

[0047] Furthermore, the first support platform 200 is also provided with a fifth cover plate 220. The fifth cover plate 220 can press against the third cover plate 260 and also fix the first workpiece 1 to be welded. By setting two cover plates, the reliability of fixing the first workpiece 1 to be welded is improved. In particular, the fifth cover plate 220 can press against the third cover plate 260, which not only improves the reliability of fixing the third cover plate 260, but also helps to simplify the external appearance of the welding fixture and avoid problems such as interference.

[0048] It is worth noting that the second cover plate 280 with the first welding wire crimping groove 222 and the first cover plate 270 with the first wire positioning part 221 are connected to the fifth cover plate 220 so that the first welding wire 31 and the wire on one side of the first workpiece to be welded 1 can be limited while the fifth cover plate 220 is being covered.

[0049] Preferably, two first welding wire crimping grooves 222 are provided to improve the reliability of positioning the first welding wire 31. Specifically, the two first welding wire crimping grooves 222 are respectively provided at both ends of the first wire positioning part 221 along the second direction. While adapting to the welding position, they can also ensure that the first welding wire 31 can be effectively positioned before and after welding, resulting in more accurate positioning.

[0050] It is worth noting that, in order to position the wire and the second welding wire 32 on the side of the second workpiece 2 away from the fifth cover plate 220, the second welding wire crimping groove 250 is provided on the side of the first support platform 200 away from the fifth cover plate 220. Simultaneously, a second wire positioning part 240 is also provided on the side of the first support platform 200 away from the fifth cover plate 220. The number, position, and purpose of the second wire positioning part 240 and the second welding wire crimping groove 250 are the same as those of the first wire positioning part 221 and the first welding wire crimping groove 222, and will not be repeated here. It is understood that the second cover plate 280 with the second welding wire crimping groove 250 and the first cover plate 270 with the second wire positioning part 240 are connected to the first support platform 200.

[0051] In this embodiment, to improve the fixing reliability of the fifth cover plate 220, a locking member 230 is provided on the first support platform 200. The locking member 230 is used to fix the fifth cover plate 220 and the first support platform 200. For example, one end of the fifth cover plate 220 along the second direction is rotatably connected to the first support platform 200, so that the fifth cover plate 220 can rotate along the first direction. The locking member 230 is used to lock the other end of the fifth cover plate 220 along the second direction. The third cover plate 260 is also rotatably disposed on the first support platform 200, making the rotational connection operation more convenient.

[0052] Optionally, a fourth cover plate 330 is provided on the second support platform 300, which is flipped relative to the second positioning structure 320. The fourth cover plate 330 is used to fix the second workpiece 2 to be welded after positioning. The end of the fourth cover plate 330 away from the first support platform 200 is rotatably disposed on the second support platform 300, and the rotation direction is perpendicular to the fifth cover plate 220, so as to minimize interference between the cover plates.

[0053] As an alternative solution for the welding fixture, to enable the driving of either the first support platform 200 or the second support platform 300 along a first direction, the welding fixture further includes a driving member 410, which drives the movement of either the first support platform 200 or the second support platform 300. Further, the second support platform 300 is slidably disposed on the base plate 100, and the driving member 410 is rotatably disposed on the base plate 100. The rotational action of the driving member 410 drives the second support platform 300 to move linearly along the first direction.

[0054] For example, the driving element 410 is configured as a cam, the outer peripheral surface of which abuts against the second support platform 300. This design is simple in structure and provides reliable driving. When the long-diameter end of the cam abuts against the second support platform 300, the second support platform 300 is located on the side closer to the first support platform 200. Preferably, the welding fixture also includes a driving handle 420, which is connected to the cam and used to drive the rotation of the cam, facilitating operation and reducing effort.

[0055] In this embodiment, the welding fixture further includes a resetting member, which tends to make the second support platform 300 and the first support platform 200 mutually oriented, so that when the long diameter end of the cam disengages from the second support platform 300, the second support platform 300 is driven to always engage with the outer peripheral surface of the cam until the outer peripheral surface of the second support platform 300 abuts against the short diameter end of the cam. Simultaneously, it also keeps the outer peripheral surface of the second support platform 300 in contact with the short diameter end of the cam. It is understood that when the second support platform 300 is positioned away from the first support platform 200, it facilitates the operator to place the first workpiece 1 and the second workpiece 2 to be welded onto the first support platform 200 and the second support platform 300, respectively.

[0056] The process of using the above-mentioned welding fixture is as follows: In the initial position, the reset component positions the second support platform 300 away from the first support platform 200; the fifth cover plate 220 and the third cover plate 260 are opened respectively, and the first workpiece to be welded 1 is loaded into the first positioning structure 210. Then, the third cover plate 260 and the fifth cover plate 220 are fastened and locked in sequence; the fourth cover plate 330 is opened, and the second workpiece to be welded 2 is loaded into the second positioning structure 320. Then, the fourth cover plate 330 is fastened and locked; the handle 420 is rotated, causing the cam to rotate, and the second support platform 300 moves closer to the first support platform 200 in the first direction, so that the welding position of the second workpiece to be welded 2 and the first workpiece to be welded 1 corresponds to the welding through hole 101 and fits together; finally, the welding fixture is placed in the welding equipment for welding. After welding is completed, the fifth cover plate 220 and the fourth cover plate 330 are opened, and finally the third cover plate 260 is opened. The welded product can then be removed from the welding fixture.

[0057] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
