Description

Technical Field

[0001] This utility model relates to the field of enameled wire welding technology, specifically to a welding device for enameled wire and tin-plated materials. Background Technology

[0002] In the electronics industry, enameled wire is often used to connect electronic components, including soldering connections with tin-plated materials. Soldering is usually done automatically using a soldering machine. However, when soldering enameled wire to tin-plated materials, trace amounts of carbide dust generated by the insulation layer and fumes generated by flux volatilization may affect the solder joint, leading to a reduction in subsequent soldering efficiency. Utility Model Content

[0003] To address the aforementioned problems, it is necessary to provide a welding device for enameled wires and tin-plated materials, addressing the issues in existing technologies.

[0004] To solve the problems of the prior art, the technical solution adopted by this utility model is as follows: a welding device for enameled wire and tin-plated materials, including a welding module, a cooling module and a dust collection module set at the welding station. The welding module includes a module fixing plate, a linear driver and a welding machine body. The linear driver is installed on the top of the module fixing plate. The working end of the linear driver moves horizontally along the coil arrangement direction on the coil carrier. The welding machine body is fixedly installed on the working end of the linear driver. The working end of the welding machine body is set vertically downward. Several dust-proof air knives are set below the welding machine body in the welding module.

[0005] To ensure the welding precision of the enameled wire and the tin-plated material, the following features are specifically designed: the welding machine body is a galvanometer laser welding machine.

[0006] To facilitate adjustment of the air blowing direction and air curtain uniformity of the dust-proof air knife, the following features are specifically included: at least two vertical guide shafts are installed on one side of the working end of the welding machine body; the dust-proof air knife includes a horizontally arranged air shaft and first open seats installed at both ends of the air shaft; the dust-proof air knife is mounted on the guide shaft through the first open seats; an air pipe connector is installed at one end of the air shaft; and several air outlets are provided on the side of the air shaft facing the welding machine body. The air outlets are evenly distributed along the axial direction of the air shaft.

[0007] Preferably, the air outlets are evenly distributed along the air axis.

[0008] To address the issue of cooling the welding points, the following features are specifically included: the cooling module comprises a mounting bracket and a vertical fixed shaft mounted on the upper side of the mounting bracket. A second open seat is rotatably mounted on the fixed shaft, and an air blowing pipe is inserted into the second open seat. The air outlet of the air blowing pipe extends to the top of the coil carrier at the welding station.

[0009] In order to collect the flying dust, the following features are specifically designed: the dust collection module includes a dust collection sheet metal box located below the cooling module, the dust collection sheet metal box has an upward opening, and one side of the dust collection sheet metal box is connected to an air suction pipe.

[0010] The advantages of this utility model compared to the prior art are:

[0011] Firstly, this invention uses an air curtain formed by a dust-proof air knife to block trace amounts of carbide dust generated by the insulation layer of the enameled wire and fumes and dust generated by flux volatilization from directly contacting the welding joint, thereby reducing the adhesion of impurities.

[0012] Secondly, this utility model uses a galvanometer laser welding machine as the welding machine body, which can accurately act on the welding part. The air curtain formed by the dust-proof air knife can reduce the interference of dust and smoke on the laser beam path, and can also protect the galvanometer mirror of the galvanometer laser welding machine, further ensuring the laser focusing accuracy.

[0013] Thirdly, the dust collection module in this utility model extracts the accumulated dust and smoke away from the welding area through the suction pipe, realizing the directional collection of flying dust and smoke, and reducing the dust residue in the welding area.

[0020] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figures 1 to 5 :

[0022] A welding device for enameled wire and tin-plated materials includes a welding module 1, a cooling module 2, and a dust collection module 3 disposed at a welding station. The welding module 1 includes a module fixing plate 1a, a linear driver 1b, and a welding machine body 1c. The linear driver 1b is mounted on the top of the module fixing plate 1a, and its working end moves horizontally along the coil arrangement direction on the coil carrier. The welding machine body 1c is fixedly mounted on the working end of the linear driver 1b, and its working end is vertically downward. Several dust-proof air knives 1d are disposed below the welding machine body 1c in the welding module 1.

[0023] In this application, during use, the enameled wire and tin-plated material to be welded are positioned by a coil carrier and moved to the welding station by a conveyor line; the linear actuator 1b moves horizontally along the coil arrangement direction on the coil carrier, driving the welding machine body 1c fixed at its working end to move sequentially to the target welding point, so that the welding machine body 1c can perform batch welding on multiple enameled wires on the coil carrier; in this embodiment, the linear actuator 1b can be a linear slide table, etc., and with the help of slide rails and hinged drag chains, etc., the stability of the welding machine body 1c during the movement is ensured; during the welding process, several dust-proof air knives 1d located below the welding machine body 1c work synchronously to form an air curtain, the cooling module 2 cools the welding area and welding head, and the dust collection module 3 collects the carbide dust and flux fumes generated by the insulation layer; after the current welding point is completed, the linear actuator 1b drives the welding machine body 1c to move to the next welding point, and the above process is repeated. In this embodiment, the air curtain formed by the dust-proof air knife 1d blocks the trace amount of carbide dust generated by the insulation layer of the enameled wire and the smoke dust generated by the flux volatilization from directly contacting the welding head, reducing the adhesion of impurities. In this embodiment, the dust collection module 3 can actively collect volatiles and dust to avoid the accumulation of impurities in the welding area, and the cooling component can cool the welding point.

[0024] To ensure the welding precision between the enameled wire and the tin-plated material, the following features are specifically designed:

[0025] The welding machine body 1c is a galvanometer laser welding machine.

[0026] Figures 1 to 3 As shown, this embodiment uses a galvanometer laser welding machine as the welding machine body 1c. Its galvanometer system can achieve high-speed and high-precision fine adjustment of the laser focus. Combined with the coarse positioning of the linear driver 1b, it significantly improves the positional accuracy of the weld point. The laser energy is concentrated and controllable, and can be precisely applied to the welding part, reducing the thermal impact on the enameled wire insulation layer and tin-plated material, and reducing the accuracy deviation caused by thermal deformation. At the same time, the air curtain formed by the dust-proof air knife 1d can reduce the interference of dust and smoke on the laser optical path, and can also protect the galvanometer mirror surface of the galvanometer laser welding machine, further ensuring the laser focusing accuracy, thereby effectively ensuring the welding accuracy.

[0027] To facilitate adjustment of the air blowing direction and air curtain uniformity of the dust-separating air knife 1d, the following features were specifically set:

[0028] At least two vertical guide shafts 1c1 are installed on one side of the working end of the welding machine body 1c. The dust-proof air knife 1d includes a horizontally arranged air shaft 1d1 and first open seats 1d2 installed at both ends of the air shaft 1d1. The dust-proof air knife 1d is mounted on the guide shaft 1c1 through the first open seats 1d2. An air pipe connector 1d3 is installed at one end of the air shaft 1d1. Several air outlets 1d4 are provided on the side of the air shaft 1d1 facing the welding machine body 1c. The air outlets 1d4 are evenly distributed along the axial direction of the air shaft 1d1.

[0029] The air outlets 1d4 are evenly distributed along the axis of the air shaft 1d1.

[0030] Figures 3 to 4 As shown, in this embodiment, the dust-proof air knife 1d is mounted on a vertical guide shaft 1c1 on one side of the working end of the welding machine body 1c via first opening seats 1d2 at both ends. Its height can be adjusted by sliding up and down along the guide shaft 1c1, and the angle of the air shaft 1d1 can be adjusted by opening and rotating the first opening seats 1d2, thereby changing the blowing direction of the air outlet 1d4. Precise adjustment of the blowing direction adapts to the dust-proof requirements of different welding point locations. The air outlets 1d4, evenly spaced along the axis of the air shaft 1d1, ensure uniform gas flow, forming a stable and continuous air curtain, preventing local impurities caused by uneven air curtains from passing through the air curtain and contacting the working end of the welding machine body 1c.

[0031] To address the issue of cooling the welding points, the following features were specifically designed:

[0032] The cooling module 2 includes a mounting bracket 2a and a vertical fixed shaft 2a1 disposed on the upper side of the mounting bracket 2a. A second open seat 2a2 is rotatably mounted on the fixed shaft 2a1. An air blowing pipe 2a3 is inserted into the second open seat 2a2. The air outlet end of the air blowing pipe 2a3 extends to the top of the coil carrier at the welding station.

[0033] like Figure 5 As shown, in this embodiment, during the welding process, the cooling gas introduced through the air blowing pipe 2a3 is directly blown to the welded point through the outlet end to achieve targeted cooling. The air blowing pipe 2a3, which is inserted into the second opening seat 2a2, can rotate within the second opening seat 2a2 along the axis. The second opening seat 2a2 can rotate flexibly around the fixed axis 2a1, thereby adjusting the air outlet direction so that the outlet end of the air blowing pipe 2a3 is accurately aligned with the welding point on the coil carrier at the welding station.

[0034] To collect the flying dust, the following features were specifically designed:

[0035] The dust collection module 3 includes a dust collection sheet metal box 3a located below the cooling module 2. The dust collection sheet metal box 3a has an upward-facing opening, and one side of the dust collection sheet metal box 3a is connected to the air suction pipe 3a1.

[0036] like Figure 5 As shown, when the dust collection module 3 in this embodiment is working, the dust collection box 3a located below the cooling module 2 faces the welding station with its opening facing upwards. The carbide dust and flux fumes generated during the welding process gather at the opening of the dust collection box 3a below under the guidance of the air curtain formed by the dust-proof air knife 1d and its own gravity. At the same time, the suction pipe 3a1 connected to one side of the dust collection box 3a is connected to a negative pressure source to generate continuous suction, which draws the gathered dust and fumes away from the welding area through the suction pipe 3a1, realizing the directional collection of dust and fumes and reducing the dust residue in the welding area.

[0037] The specific working process of this embodiment is as follows: During use, the enameled wire and tin-plated material to be welded are positioned by the coil carrier and moved to the welding station in conjunction with the conveyor line; the linear driver 1b moves horizontally along the coil arrangement direction on the coil carrier, driving the welding machine body 1c fixed at its working end to move sequentially to the target welding point, so that the welding machine body 1c performs batch welding on multiple enameled wires on the coil carrier; during the welding process, several dust-proof air knives 1d located below the welding machine body 1c work synchronously to form an air curtain, the cooling module 2 cools the welding area and welding head, and the dust collection module 3 collects the carbide dust and flux fumes generated by the insulation layer.

[0038] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they 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.
