[0002] The welding of multi-strand leads of vehicle-mounted transformers is usually done manually using traditional soldering furnaces. The welding process involves workers holding the product, applying flux to the leads with a brush, and then welding. This repetitive work results in high labor intensity, inconsistent welding quality, and difficulty in controlling the amount of flux used. In addition, the high temperature of the soldering furnace poses safety risks. Utility Model Content

[0006] A wave soldering apparatus includes flux nozzles and wave soldering nozzles disposed around the robotic arm, wherein both flux nozzles and wave soldering nozzles are facing upwards;

[0007] A feeding and positioning fixture is provided on the side of the flux nozzle away from the robotic arm. The feeding and positioning fixture includes a base plate, two end positioning strips respectively provided on both sides of the base plate, a plurality of pads provided between the two end positioning strips, and a C-shaped clamp that holds the top of the product. The pads extend in the same direction as the end positioning strips, the height of the pads is lower than the end positioning strips, and both end positioning strips are provided with positioning grooves facing each other.

[0008] A receiving box is disposed on the side of the wave soldering nozzle away from the robotic arm.

[0009] Preferably, the system further includes a control system, which includes a controller and a material detection sensor disposed on one side of the feeding and positioning fixture. The robotic arm, the wave soldering device, and the material detection sensor are all electrically connected to the controller.

[0010] Preferably, the end positioning strip is provided with a plurality of positioning grooves in sequence along the length direction, and a material detection sensor is provided on one side of each positioning groove.

[0011] Preferably, the material detection sensor is a photoelectric sensor or an inductive sensor.

[0012] Preferably, the receiving box is provided with multiple receiving slots.

[0013] The beneficial effects of this utility model are: it designs an automatic operating equipment that can complete feeding, flux spraying, welding, and unloading, which improves welding efficiency, reduces the labor intensity of workers, and lowers labor costs; it uses wave soldering to weld product leads, resulting in good and stable welding quality, and the amount of welding materials such as flux used in each welding is almost consistent.

[0019] The embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement them after reading this specification. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0020] This utility model provides, for example Figure 1-4 The wave soldering automatic welding system shown includes a robotic arm 10 and a wave soldering device, a loading and positioning fixture 30, a receiving box 40 and a control system arranged around it, so that the range of motion of the robotic arm 10 covers the wave soldering device, the loading and positioning fixture 30 and the receiving box 40.

[0021] The robotic arm 10 is equipped with an electric gripper at its end for gripping the product 60 to be welded.

[0022] The wave soldering device, referencing relevant technologies, includes a flux nozzle 21 and a wave soldering nozzle 22, both positioned around the robotic arm 10, with both nozzles facing upwards to facilitate the application of flux and solder to the bottom pins of the product 60 to be soldered and to complete the soldering process. The loading and positioning fixture 30 is positioned on the side of the flux nozzle 21 away from the robotic arm 10, and the receiving box 40 is positioned on the side of the wave soldering nozzle 22 away from the robotic arm 10. This allows the robotic arm 10 to pick up the product 60 to be soldered from the loading and positioning fixture 30, sequentially transfer it above the flux nozzle 21 and wave soldering nozzle 22 for soldering, and then transfer it into the receiving box 40, forming a shorter movement path.

[0023] The loading and positioning fixture 30 is used to place the products 60 to be welded in an orderly manner for easy gripping by the robotic arm 10. It includes a base plate 31 and two end positioning strips 32 respectively disposed on both sides of the base plate 31. Each end positioning strip 32 has a positioning groove 321 facing away from it. The two positioning grooves 321 respectively fit with the two ends of the product 60 to be welded, forming a loading position that holds the product 60 in the middle. The end positioning strips 32 have eight positioning grooves 321 evenly spaced along their length, accommodating eight products to be welded. Multiple pads 33 are also disposed between the two end positioning strips 32 to support the product 60 to be welded and prevent its pins from directly contacting the base plate 31 and causing displacement. The pads 33 extend in the same direction as the end positioning strips 32, and their height is lower than that of the end positioning strips 32. The loading and positioning fixture 30 also includes a C-shaped clamp 34 that holds the top of the product, facilitating gripping by the robotic arm 10 and pressing certain component pins against the PCB board of the product to be welded. When changing to a different product model, only the loading and positioning fixture for the relevant product needs to be replaced.

[0024] The control system includes a controller and a material detection sensor 51 disposed on one side of the loading and positioning fixture 30. The robotic arm 10, the wave soldering device, and the material detection sensor 51 are all electrically connected to the controller. The controller includes a host computer and a slave computer. The host computer can be a computer or a server, and the slave computer can be a programmable logic controller (PLC). It receives signals from each component and sends instructions to each component. The material detection sensor 51 can be a photoelectric sensor or an inductive sensor, disposed on one side of the positioning slot 321, and is used to determine whether there is a product to be welded at the loading position, facilitating the operation of the robotic arm 10.

[0025] The receiving box 40 is equipped with four receiving slots 41. The welded products are placed into the receiving slots 41 by the robotic arm 10.

[0026] The above describes one or more embodiments of this utility model in a relatively specific and detailed manner, but it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
