Description

Technical Field

[0001] The utility model relates to the technical field of wire harness welding, in particular to a secondary sealing welding machine for automobile wire harnesses. Background Art

[0002] Wire harness welding is the process of tightly fitting the wires of a wire harness and maintaining them at a certain temperature and pressure for a period of time to fuse the contact surfaces. Ultrasonic metal welding uses high-frequency vibration waves to transmit to the two metal surfaces to be welded. Under pressure, the two metal surfaces rub against each other to form a fusion between the molecular layers. Currently, when welding the wires in a wire harness to one end of a metal workpiece, the wires are mostly overlapped with a plane of the metal workpiece before the welding operation is performed. Relying on only one surface for contact and welding, the stability of the connection is limited.

[0003] The existing patent number CN220427131U discloses a wire harness welding device, comprising a mounting plate, a fixing plate welded to the lower end of one side of the mounting plate, a base welded to the upper end of the fixing plate, a fixing bracket welded to the upper end of one side of the mounting plate, a cylinder extending through the fixing bracket, a pressing head connected to the lower end of the cylinder, a mounting bracket provided on one side of the mounting plate corresponding to the fixing bracket, and an ultrasonic energy supply assembly provided between the inner wall of the mounting bracket and the mounting plate. This device is rationally designed, and the wire harness welding device separates the wire extending from one end of the wiring harness sleeve and distributes it above and below one end of the workpiece. The ultrasonic energy supply assembly is then activated, causing a vibration welding head to move toward the workpiece, contacting the wire and vibrating at high speed. The wire heats up and, under the pressure of the two vibration welding heads, can be welded and fixed to both sides of the workpiece.

[0004] The above-mentioned existing technical solutions have the following defects: after welding, it is necessary to wait for the welding point to cool naturally, the welder lacks a heat dissipation device, and it takes a long time to wait for the welding point to completely cool down. In addition, the temperature drop at the microscopic level is locally uneven, and the solidification uniformity is poor. Utility Model Content

[0005] The utility model aims to provide a secondary sealing welding machine for automobile wiring harnesses.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The utility model comprises a mounting plate, wherein the mounting plate is fixedly provided with a secondary welding assembly, and the secondary welding assembly comprises a fixing bracket and a mounting bracket fixedly provided on the top wall of the mounting plate, the fixing bracket is penetrated by a cylinder, the lower end of the cylinder is connected to a pressing head, an ultrasonic energy supply assembly is provided between the inner wall of the mounting bracket and the mounting plate, the outer wall of the mounting plate is hingedly provided with an arc-shaped combination cover covering the secondary welding assembly, the combination cover comprises a left half cover and a right half cover hingedly provided on opposite sides of the mounting plate, the ends of the left half cover and the right half cover are magnetically adsorbed to each other, the top wall of the mounting plate is fixedly provided with a receiving bracket located between the pressing head and the ultrasonic wave, an arc-shaped wire groove is opened in the extension direction of the top wall of the receiving bracket, an upper cover covering the arc-shaped wire groove is extended on the inner side of the right half cover, the upper cover is abutted against the receiving bracket, a porous cover plate covering the two ports of the arc-shaped wire groove is extended on the inner side of the left half cover, a cooling fan is fixedly provided on the inside of the porous cover plate, and the cooling fan is cooperated with a driving motor, and the driving motor is externally powered.

[0008] By adopting the above technical solution, after the initial welding of the wiring harness is completed and the wiring harness is initially fixed, the wiring harness is sent to the secondary welding assembly for secondary reinforcement welding. After the secondary welding is completed, the wiring harness is placed in the arc-shaped wire groove of the receiving frame, and then the left half cover and the right half cover are closed. At this time, the left half cover and the right half cover are magnetically fixed, the upper cover contacts the receiving frame, and the porous cover plate closes both ends of the arc-shaped wire groove. The driving motor starts the cooling fan. The cooling fans are set in pairs with the same rotation direction, and the arc-shaped wire groove is closed. The airflow flows steadily from one end and is steadily extracted from the other end. A stable airflow is formed inside the arc-shaped wire groove to evenly cool the welding points of the wiring harness, ensuring stable cooling and rapid solidification at the welding points, thereby improving the efficiency and quality of the secondary welding. The holes on the porous cover plate allow the airflow to flow freely while also effectively filtering impurities in the air to avoid affecting the welding quality of the wiring harness.

[0009] Furthermore, the left half cover and the right half cover are arc-shaped, the outer wall of the porous cover plate is extended with a first connecting column connected to the left half cover, the outer wall of the upper cover is extended to the right with a second connecting column connected to the right half cover, and the outer walls of the left half cover and the right half cover are fixed with pull buttons.

[0010] By adopting the above technical solution, the setting of the pull button makes it easier for the operator to exert force to open or close the combination cover, and the first connecting column and the second connecting column effectively connect the porous cover plate and the upper cover, allowing the two to move stably.

[0011] Furthermore, end plates are extended from both ends of the supporting frame, and the end plates are provided with fitting grooves for the porous cover plates to be fitted and placed. The outer wall of the porous cover plate is extended with a limit block that fits the outer wall of the upper cover, and several soft supporting ropes are connected to both sides of the groove wall of the arc-shaped wire groove, and the soft supporting ropes are arranged along the length direction of the arc-shaped wire groove.

[0012] By adopting the above technical solution, after the secondary welding is completed, the right half cover is closed first to cover the upper cover, and then the left half cover is closed. When the porous cover plate is embedded in the fitting groove, the limit block simultaneously contacts the outer wall of the upper cover to limit the range of movement of the upper cover. The right half cover can be opened only after the left half cover is opened. While the arc-shaped wire trough is tightly closed, it also has good operational rationality, avoiding accidental opening of the upper cover during the cooling process of the welding point to affect the cooling effect. The setting of the soft connecting rope has good connecting properties, so that the wire harness is suspended and placed, which is convenient for full-angle cooling, ensuring uniform and stable cooling of the welding point during the cooling process, and ensuring the welding quality.

[0013] Furthermore, a magnetic protrusion is fixedly provided on one end of the right half cover close to the left half cover, and a magnetic groove matching the magnetic protrusion is opened on one end of the left half cover close to the right half cover.

[0014] By adopting the above technical solution, the magnetic protrusion cooperates with the magnetic groove in an interlocking magnetic manner, thereby improving the firmness of the connection between the left half cover and the right half cover, and making it difficult to be easily opened by external force.

[0015] In summary, the beneficial technical effects of the present invention are:

[0016] 1. A combination of cover, support frame, curved wire trough, upper cover, porous cover plate and cooling fan is used to generate a stable airflow inside the curved wire trough to evenly cool the welding points of the wire harness, ensuring stable cooling and rapid solidification at the welding points, thereby improving the efficiency and quality of secondary welding;

[0017] 2. The end plates, fitting grooves and limit blocks are used to produce a tightly closed arc-shaped wire duct while also ensuring good operational rationality, thus preventing the upper cover from accidentally opening during the cooling process of the welding point.

[0018] 3. A soft connecting rope is used to make the wiring harness suspended, which is convenient for full-angle cooling and ensures the uniform and stable cooling effect of the welding point during the cooling process. BRIEF DESCRIPTION OF THE DRAWINGS
