Description

Technical Field

[0001] This invention relates to the field of electrical connector manufacturing technology, and in particular to a welding apparatus for electrical connector manufacturing. Background Technology

[0002] Electrical connectors are electromechanical components that connect circuits and transmit electrical signals and energy. They are widely used in aerospace, automotive and other fields. They consist of plugs, sockets and other components to ensure reliable connections and facilitate plugging and unplugging.

[0003] When processing the cables at one end of an electrical connector, laser welding is required. Because multiple cables are connected in a loop, the concentrated energy of laser welding can precisely heat the solder joints, achieving a firm connection between each cable and the connector, reducing contact resistance, improving conductivity and stability, and adapting to complex environments such as vibration. Traditionally, when welding cables to electrical connectors, the cables need to be butt-jointed to one end of the connector, and then the welding equipment needs to be moved close to the welding position to complete the welding. After welding, the connector needs to be rotated so that the next welding position is facing upwards before welding again. The welding operation is cumbersome, and manual welding is risky and reduces accuracy. This results in differences in the welding strength between the cable and the connector end, making it impossible to guarantee that the cables at the connector end can maintain a firm and uniform weld, affecting the subsequent production quality of electrical connectors.

[0004] Based on this, a welding device for the production of electrical connectors is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a welding apparatus for the production of electrical connectors in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A welding device for manufacturing electrical connectors includes a welding block with a support frame connected to its lower end. A through hole is formed on the welding block, and a welding post is connected within the through hole. A welding head is connected to the lower end of the welding post. The welding post is connected to the welding block via a cylinder, which is located on one side of the welding block. A connection cover is provided below the welding block, and an electrical connector is fixedly connected to the connection cover. A rotating disk is connected to one side of the connection cover. A transmission mechanism is connected between the rotating disk and the cylinder to drive the rotating disk to rotate intermittently, thereby cooperating with the welding head to perform laser welding on the cable ends of the electrical connector.

[0008] Preferably, a limit ring is connected to one side of the support frame.

[0009] Preferably, a connecting plate is connected to the welding column, and the connecting plate is fixedly connected to the telescopic end of the cylinder.

[0010] Preferably, a fixing hoop is connected to the cylinder, and the fixing hoop is fixedly connected to the outside of the welding block.

[0011] Preferably, the welding block has a side groove, which is connected to the through hole. A deflection tube is rotatably connected to one side of the welding block, and a torsion spring is connected to the deflection tube.

[0012] Preferably, a fixing plate is connected to one side of the welding block, a deflection shaft is connected to one side of the deflection tube, the deflection shaft is rotatably connected to the fixing plate, a torsion spring is sleeved on the deflection shaft, one end of the torsion spring is connected to the fixing plate, a button bracket is connected to one side of the fixing plate, and a control button is connected to the button bracket.

[0013] Preferably, a slide rail is connected to one side of the rotary disk, and a slider is connected to the slide rail via an electric push rod. An extrusion plate is connected to the slider, and the extrusion plate abuts against the outside of the connecting cover.

[0014] Preferably, the transmission mechanism includes a rack, which is rotatably connected to one side of the connecting plate via an extension rod. One end of the extension rod is connected to one end of the connecting plate, and a nut is connected to the extension rod. The rotating disk is connected to a ratchet via a rotating shaft. A telescopic column is connected to one side of the welding block, and a V-shaped frame is connected to one end of the telescopic column. The rotating shaft is rotatably connected to the V-shaped frame.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. This application adopts a rack and pinion structure, which uses the rack and pinion to drive the ratchet to rotate intermittently, thereby driving the electrical connector to rotate. This causes the position to be welded to rotate to below the welding head. As the welding column descends, the laser welding of the welding position is completed. When the welding column descends, the ratchet does not rotate, which improves the orderliness of the welding operation.

[0017] 2. This application adopts a deflection tube structure, with an internal suction tube connected to the deflection tube. When the welding column descends, the deflection tube is deflected, causing the deflection tube to press the control button. Therefore, the suction tube is activated simultaneously during welding to remove the fumes generated during welding, thus avoiding the impact of fumes generated during laser welding on the welding quality.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-5 The present invention provides a technical solution:

[0027] A welding device for manufacturing electrical connectors includes a welding block 1, with a support frame 2 connected to the lower end of the welding block 1 to ensure the stability of the welding block 1 structure. A through hole 26 is provided on the welding block 1, and a welding post 6 is connected inside the through hole 26. A lead wire for controlling a welding head 27 to perform welding is connected to the upper end of the welding post 6, and the welding head 27 is connected to the lower end of the welding post 6. The welding head 27 can weld electrical connectors using laser welding. The welding post 6 is connected to the welding block 1 via a cylinder 21, which is connected to one side of the welding block 1. A connecting cover 17 is provided below the welding block 1, and the electrical connector is fixedly connected to the connecting cover 17. During welding, the electrical connector needs to be fixed inside the connecting cover 17. A rotating disk 11 is connected to one side of the connecting cover 17, and a transmission mechanism is connected between the rotating disk 11 and the cylinder 21 to drive the rotating disk 11 to rotate intermittently, cooperating with the welding head 27 to perform laser welding on the cable ends of the electrical connector.

[0028] Specifically, such as Figure 1As shown, a limiting ring 3 is connected to one side of the support frame 2. For long cables connected to one end of the electrical connector, they can be placed uniformly on the limiting ring 3 to avoid the problem of the cable connected to one end getting tangled and knotted when the electrical connector rotates during soldering. The limiting ring 3 plays a very good storage role.

[0029] Specifically, such as Figure 1 As shown, a connecting plate 7 is connected to the welding column 6. The connecting plate 7 is horizontally arranged and is fixedly connected to the telescopic end of the cylinder 21. The telescopic end of the cylinder 21 and the connecting plate 7 are perpendicular to each other.

[0030] Specifically, such as Figure 3 As shown, a fixing hoop 24 is connected to the cylinder 21. The fixing hoop 24 is fixedly connected to the outside of the welding block 1. The fixing hoop 24 ensures the structural connection of the cylinder 21.

[0031] Specifically, such as Figure 4 and Figure 5 As shown, a side groove 4 is provided on the welding block 1, and the side groove 4 is connected to the through hole 26. A deflection tube 5 is rotatably connected to one side of the welding block 1, and a torsion spring 19 is connected to the deflection tube 5. When welding, one end of the deflection tube 5 abuts against the outside of the welding column 6. When not welding, one end of the deflection tube 5 is set in the through hole 26, wherein the torsion spring 19 drives the deflection tube 5 away from the side of the control button 20.

[0032] Specifically, such as Figure 4 As shown, a fixing plate 10 is connected to one side of the welding block 1, and a deflection shaft 18 is connected to one side of the deflection tube 5. The deflection shaft 18 is rotatably connected to the fixing plate 10. A torsion spring 19 is sleeved on the deflection shaft 18, and one end of the torsion spring 19 is connected to the fixing plate 10. A button bracket 14 is connected to one side of the fixing plate 10, and a control button 20 is connected to the button bracket 14. The control button 20 can control whether the exhaust pipe set in the deflection tube 5 is running. When the exhaust pipe is running, it can suck the fumes generated during laser welding into the exhaust pipe, avoid fumes from polluting the working environment, improve welding quality, and through the structure of the deflection tube 5, welding and exhaust can be carried out simultaneously, ensuring stable welding operation. When the control button 20 is pressed, the exhaust pipe runs.

[0033] Specifically, such as Figure 5As shown, a slide rail 12 is connected to one side of the rotating disk 11. The slide rail 12 is connected to a slider 16 via an electric push rod. By controlling the electric push rod, the slider 16 can be driven to slide on the slide rail 12, thereby enabling the extrusion plate 13 to clamp the connecting cover 17, ensuring the firmness of the electrical connector connection. The extrusion plate 13 is connected to the slider 16. The extrusion plate 13 has a vertical angle bend. The extrusion plate 13 fits perfectly with the positive frame structure of the connecting cover 17. The extrusion plate 13 abuts against the outside of the connecting cover 17. When the connecting cover 17 is fixed, the electrical connector is positioned at the center of the rotating disk 11.

[0034] Specifically, such as Figure 4 As shown, the transmission mechanism includes a rack 9 with counter-teeth that engage with a ratchet 15 when moving upwards. The rack 9 is rotatably connected to one side of the connecting plate 7 via an extension rod 8. One end of the extension rod 8 is connected to one end of the connecting plate 7, and a nut 25 is connected to the extension rod 8. The position of the rack 9 connected to the extension rod 8 can be adjusted via the nut 25. The rotating disk 11 is connected to the ratchet 15 via a rotating shaft. A telescopic column 22 is connected to one side of the welding block 1. The horizontal position of the electrical connector can be adjusted via the telescopic column 22, thereby adjusting the welding position of the electrical connector to ensure that the welding head 27 is directly above the welding area. One end of the telescopic column 22 is connected to a V-frame 23, and the rotating shaft is rotatably connected to the V-frame 23. The V-frame 23 stabilizes the connection of the rotating disk 11.

[0035] In summary, the welding device for producing electrical connectors provided in this embodiment requires multiple cables to be plugged into the port when welding port cables of the electrical connector. Then, the electrical connector is assembled onto the connecting cover 17. The slider 16 is controlled to slide on the slide rail 12, thereby driving the extrusion plate 13 to clamp the connecting cover 17. There are four sliders 16, and the four sliders 16 can slide on each slide rail 12 at the same time, thereby fixing the connecting cover 17 at the center position of the rotating disk 11. The transmission structure of the slider 16 on the slide rail 12 is a direct reference to the prior art. The fixing of the electrical connector structure is completed by the slider 16 driving the extrusion plate 13 to move.

[0036] After the electrical connector structure is fixed, the telescopic column 22 can be controlled to extend and retract, thereby driving the V-shaped frame 23 to move horizontally, so that the electrical connector moves below the welding block 1, moving the area to be welded on the electrical connector to directly below the through hole 26, and adjusting the nut 25 so that the rack 9 and the ratchet 15 are on the same vertical plane.

[0037] The cylinder 21 is activated, extending to raise the connecting plate 7. This, in conjunction with the extension rod 8, causes the rack 9 to move upwards. Because the rack 9 has a reverse tooth structure, as it rises, it synchronously rotates the ratchet 15. The rack 9 is tilted, ensuring that its upward movement drives the ratchet 15 to rotate, causing the area of ​​the cable to be soldered on the electrical connector to rotate below the through hole 26. The cylinder 21 then retracts, causing the rack 9 to move downwards, but without rotating the ratchet 15. This interaction between the rack 9 and ratchet 15 achieves a unidirectional rotation effect on the electrical connector. When the soldering post 6 moves downwards and contacts the deflection tube 5... The deflection tube 5 can be driven to rotate around the deflection axis 18. When the deflection tube 5 rotates, it can contact the control button 20. The control button 20 can control the air extraction pipe structure used to remove the fumes generated during welding. The air extraction pipe is connected inside the deflection tube 5. When welding is completed, the control button 20 is automatically pressed. When welding is completed, the welding column 6 is reset. At this time, the deflection tube 5 is reset under the action of the torsion spring 19. The control button 20 is not pressed, and the air extraction pipe structure stops operating. The fumes generated by laser welding are removed in time, which can effectively ensure the welding quality and prevent the fumes generated by welding from falling into the welding area and reducing the welding quality.

[0038] As the cylinder 21 reciprocates, it can drive the electrical connector to rotate and weld at a uniform speed. The rotation angle of the electrical connector is related to the upward movement distance of the rack 9 and the size of the ratchet 15. By adjusting the extension speed and extension length of the cylinder 21, the welding efficiency can be adjusted automatically. This device can be adapted to the welding of cable ends of electrical connectors of various sizes, greatly improving the welding quality.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
