Description

Technical Field

[0001] This application relates to equipment or methods specifically for manufacturing, assembling, maintaining or repairing line connectors or current collectors, or for connecting electrical conductors, and more specifically to an ultrasonic wire crimping device. Background Technology

[0002] In the field of wire harness manufacturing, terminal crimping is a core process for connecting wires and terminals, and its quality directly affects the reliability of electrical connections and the stability of equipment operation. While existing terminal crimping processes and equipment are widely used, they still require three independent steps: wire stripping, terminal fitting, and crimping. During crimping, wire positioning still relies on manual labor, which limits efficiency. Furthermore, improper wire crimping often leads to poor contact between the wire and terminal, making the wire cross-section prone to breakage and affecting product performance.

[0019] Reference Figure 1-3 This application proposes an embodiment of an ultrasonic wire crimping device, which includes a worktable 10 and an ultrasonic welding electrode 20, a horizontal crimping member 30, and a vertical crimping member 40 mounted on the worktable 10. The horizontal crimping member 30 is disposed at the upper end of one side of the ultrasonic welding electrode 20 via a horizontal displacement mechanism 50, and the vertical crimping member 40 is disposed on the other side of the ultrasonic welding electrode 20 via a lifting mechanism 60. The horizontal displacement mechanism 50 is used to drive the horizontal crimping member 30 to move closer to or away from the vertical crimping member 40, and the lifting mechanism 60 is used to drive the vertical crimping member 40 to rise and fall.

[0020] When using the ultrasonic wire crimping device described in this embodiment, two wires to be welded are placed on the upper end of the ultrasonic welding electrode 20 and pressed against the vertical crimping member 40. The ultrasonic welding electrode 20 begins to generate ultrasonic vibration. At this time, the horizontal displacement mechanism 50 drives the horizontal crimping member 30 to move closer to the vertical crimping member 40 and presses the wires onto the vertical crimping member 40, then remains stationary for a period of time. Simultaneously, the lifting mechanism 60 drives the vertical crimping member 40 to descend a certain distance and remains stationary for a period of time. The horizontal displacement mechanism 50 then drives the horizontal crimping member 30 to move away from the vertical crimping member 40 and reset. The lifting mechanism 60 then drives the vertical crimping member 40 to rise and reset, completing the wire welding. Compared with the prior art, there is no need to use terminals to connect the wires, ensuring a firm and reliable conductive connection; the two wires will not be damaged by crimping under the action of ultrasound, ensuring product quality stability.

[0021] Preferably, the device also includes insulating contact portions 70 disposed on opposite sides of the ultrasonic welding electrode 20 and a liftable detection mechanism 80 disposed above the ultrasonic welding electrode 20. The detection mechanism 80 is provided with contacts 81 that match the two insulating contact portions 70, and the two contacts 81 are connected to the resistance measuring instrument 100.

[0022] After the two wires of the wire harness are connected, the two connected wires are placed on the insulating contact part 70. At this time, the detection mechanism 80 descends so that the two contacts 81 contact the two ends of the welded joint of the two wires respectively, and the resistance of the welded joint of the two wires is measured by the resistance measuring instrument 100. According to the measurement result of the resistance measuring instrument 100, if the measurement result is within the preset range, the two wires are judged to be qualified for welding. If the measurement result is outside the preset range, the two wires are judged to be unqualified for welding. This allows the two wires to be tested for qualification after the connection is completed, avoiding the impact of welding on the performance of the wire harness.

[0023] Specifically, the insulating contact portion 70 is the upper end of the ultrasonic welding electrode 20, and the upper end of the ultrasonic welding electrode 20 is provided with an insulating coating. The wires are placed on the upper end of the ultrasonic welding electrode 20, which has an exposed portion. In this embodiment, the insulating contact portion 70 is located at the edge of the ultrasonic welding electrode 20, ensuring that the contact point 81 can contact the exposed portion of the wire, and simultaneously enabling the detection of the resistance of the two welding portions, ensuring that the two contacts 81 can effectively detect the resistance of the welding electrode portion.

[0024] Based on the above, the testing mechanism 80 includes a lifting unit 82 and a mounting component 83. The lifting unit 82 is mounted on the workbench 10 and located on the side of the vertical pressing member 40 opposite to the ultrasonic welding electrode 20. The mounting component 83 is mounted on the lifting end within the lifting unit 82, and the contact point 81 is disposed on the mounting component 83. (See attached diagram.) Figure 1 As shown, Figure 1 Contact 81 is located on the underside of mounting component 83. Figure 1 The diagram shows the arrangement of contact 81 on the underside of the mounting component.

[0025] The horizontal crimping members 30 are distributed on the side of the workbench 10 closest to the worker, and the mounting member 83 is located on the side of the vertical crimping member 40 away from the ultrasonic welding electrode 20, so as to avoid the detection mechanism 80 from affecting the manual placement of the wires. After the welding of the two wires is completed, the horizontal crimping member 30 and the vertical crimping member 40 are reset. The lifting unit 82 drives the mounting member 83 to descend so that the two contacts 81 on the mounting member 83 contact the welding point and detect the resistance. After the resistance detection is completed, the lifting unit 82 drives the mounting member 83 to rise and return to its original position. The worker can then take out the wires that have completed the resistance detection and place the two wires to be welded next on the ultrasonic welding electrode 20.

[0026] Preferably, the system also includes a controller and an alarm 90 mounted on the workbench 10, wherein the alarm 90 and the resistance meter 100 are electrically connected to the controller. (See attached diagram.) Figure 3 The diagram illustrates the working principle of the alarm described in this embodiment. Based on the measurement results of the resistance measuring instrument 100, the resistance measuring instrument sends the detection results to the controller. If the measurement results are within the preset range, it is determined that the two wires are welded successfully, and the alarm 90 will sound. If the measurement results are outside the preset range, the alarm 90 will not sound.

[0027] Specifically, the alarm 90 is a buzzer. In another embodiment, the alarm 90 may also be a light alarm 90.

[0028] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
