[0019] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] See also Figures 1 to 4 As shown, the utility model discloses a dual-purpose welding tool, including a first tray 1 and a second tray 2, wherein the second tray 1 is detachably nested in the first tray 2, and the second tray 2 is provided with a workpiece slot 21 for placing workpieces to be welded, so that the first tray 1 and the second tray 2 are nested and matched to adapt to the first welding device, and the first tray 1 and the second tray 2 are separated to make the second tray 2 adapt to the second welding device.

[0021] The utility model is adapted to the first welding device or the second welding device respectively by nesting and connecting or separating the first pallet 1 and the second pallet 2, and the workpiece to be welded is placed in the workpiece slot 21 of the second pallet 2, so that the tooling is adapted to the first welding device or the second welding device according to whether the second pallet 2 is nested and matched with the first pallet 1. During the transfer of the workpiece between the two welding devices, it is not necessary to repeatedly disassemble and assemble the workpiece, but only the second pallet needs to be disassembled and assemble, and a second pallet 2 is provided with a plurality of workpiece slots 21, so the workload of disassembling and assembling the pallet 2 is less than the workload of disassembling and assembling the workpiece, saving disassembly and assembly time and manpower.

[0022] See also Figure 5 As shown, a second pallet 2 of this example is provided with four workpiece slots 21 , so that each second pallet 2 can accommodate four workpieces 100 . In other embodiments, the second pallet 2 may be provided with six, eight or more workpiece slots 21 .

[0023] Since the workpiece 100 is mounted on the second tray 2, in order for the first welding device to contact the workpiece 100 to perform welding on the workpiece 100, the first tray 1 is provided with a through slot 11, and the second tray 2 covers the through slot 11, so that the welding head of the first welding device passes through the through slot 11 to perform welding. In this example, one through slot 11 is correspondingly provided for one second tray 2 to increase the activity space of the welding head of the first welding device. In other embodiments, one second tray 2 may be provided with a plurality of through slots 11 corresponding to welding points.

[0024] See also Figures 1 to 5As shown, the first tray 1 is a structure matching the first welding device, and the workpiece 100 is placed on the second tray 2. In order to make the welding position more accurate, the relative position between the first tray 1 and the second tray 2 should be controlled. Therefore, the first tray 1 is provided with a flange 12 surrounding the through groove 11, and the flange 12 forms an installation limit structure of the second tray 2. In this example, the flange 12 is formed by extending inward from the side wall of the through groove 11, and the upper surface of the flange 12 has a height difference with the upper surface of the first tray 1 body, so that the upper surface of the flange 12 forms a first annular groove, the second tray 2 is placed in the first annular groove, and the second tray 2 is provided with a second annular groove matching the first annular groove, so that the first annular groove and the second annular groove cooperate to form an installation limit between the first tray 1 and the second tray 2. In other embodiments, the flange 12 can also be an annular protrusion convexly provided on the upper surface of the first tray 1, and the inner side wall of the annular protrusion forms a limit match with the outer side wall of the second tray 2.

[0025] During the welding process, the first pallet 1 and the second pallet 2 move frequently. In order to avoid the second pallet 2 from unexpectedly moving relative to the first pallet 1 during the movement, a fixing structure is provided between the first pallet 1 and the second pallet 2, and the fixing structure is used to connect and fix the first pallet 1 and the second pallet 2. In this example, the fixing structure is a first buckle 3 provided on the first pallet 1, and the first buckle 3 is rotatably connected to the first pallet 1, and the second pallet 2 is pressed onto the first pallet 1 by means of the rotation of the first buckle 3. More specifically, the first buckle 3 is a square or oval non-circular clamping block, which is rotated to correspond to the second pallet 2 and press the second pallet 2 onto the first pallet 1, or rotated to keep the second pallet 2 away from the second pallet 2 so that the second pallet 2 can be disassembled from the first pallet 1. In other embodiments, the fixing structure can also be a bolt and nut structure penetrating the first pallet 1 and the second pallet 2.

[0026] The second tray 2 is provided with a cover plate 4 covering the workpiece slot 21. The cover plate 4 covers the second tray 2, so that the cover plate 4 can press the workpiece 100 to be welded on the workpiece slot 21 to prevent the workpiece 100 from falling, and the cover plate can also press the parts on the workpiece 100 that are not installed in place toward the working slot 21, so that multiple parts to be welded are installed in place. The workpiece 100 to be welded in this example refers to a circuit board with multiple electronic components, and the cover plate 4 can press the electronic components that are not installed in place toward the circuit board body to install them in place.

[0027] The second tray 2 is provided with a second buckle 5, which includes a connecting portion 51 and a crimping portion 52. The connecting portion 51 is connected to the second tray 2, and the crimping portion 52 is used to press the cover plate 4 onto the second tray 2. The connecting portion 51 and the second tray 2 are respectively provided with through holes, and bolts pass through the through holes of the connecting portion 51 and the second tray 2 to connect the connecting portion 51 and the second tray 2. The crimping portion 52 is formed by extending from one side of the connecting portion 51, and its lower surface contacts the upper surface of the cover plate 4, thereby pressing the cover plate 4 onto the second tray 2. The second buckle 5 and the second tray 2 may be fixedly connected or rotatably connected in relative motion. If it is a fixed connection, the cover plate 4 can be disassembled and fixed by disassembling the second buckle 5 from the second tray 2; if it is a rotatable connection, the crimping portion 42 can be separated from the cover plate 4 or pressed onto the cover plate 4 by rotating the second buckle 5. The rotatable connection between the second buckle 5 and the second tray 2 can be achieved by replacing the bolts with pins or slightly loosening the bolts.

[0028] In this example, one first tray 1 is provided with two second trays 2, that is, each first tray 1 has two through slots 11, and each through slot 11 is provided with a second tray 2. In other embodiments, one first tray 1 may be provided with one or more than two second trays 2, and the number thereof may be specifically determined according to the sizes of the first welding device and the second welding device.

[0029] The first welding device referred to in this example is a selective welding device, and the second welding device is an automatic welding device. In other embodiments, the first welding device and the second welding device may also be other types of welding devices, but it should be noted that the first tray and the second tray can be nested or separated to be adapted to the two welding devices respectively. The workpiece 100 to be welded in this example is a circuit board, and in other embodiments, it may be any two or more parts to be welded.

[0030] The working process of the utility model is as follows: the first pallet 1 and the second pallet 2 are nested and installed, and the second pallet 2 is pressed onto the first pallet 1 by the first buckle 3, the workpiece 100 is placed on the workpiece slot 21 of the second pallet 2, the cover plate 4 is covered and the cover plate 4 is pressed onto the second pallet 2 by the second buckle 5, and the tooling jig formed by the nesting of the first pallet 1 and the second pallet 2 is placed into the first welding equipment for welding operation. After the welding of the first welding equipment is completed, the first buckle 3 is released, the second pallet 2 is removed, and the removed second pallet 2 is placed into the second welding equipment for welding operation, all welding is completed, and the workpiece 100 is removed.
