Description

Technical Field

[0001] The present invention relates to the technical field of wire harness processing, and particularly to an electronic wire harness processing and terminal crimping device based on electrical automation control. Background Art

[0002] The process of terminal crimping in electronic wire harness processing is an important link, which mainly serves to firmly connect the wire harness to the interface of the electronic device. This process not only ensures the stable transmission of current and signals, but is also crucial for the normal operation of the electronic device. The process flow of electronic wire harness terminal crimping includes several key steps: wire stripping, terminal insertion, and crimping. In the wire stripping step, the operator needs to precisely strip the wire core to ensure the consistency of the wire core length; terminal insertion is to insert the stripped wire core through the hole of the terminal head, and this step requires ensuring that the wire core is neat and undamaged; finally, crimping tightly combines the terminal and the wire core through a crimping tool to form a reliable electrical connection.

[0003] Currently, the terminals of electronic wire harnesses need to be completed by multiple people and multiple processes during the extrusion process. Usually, manual operation is required to socket the terminals, and then the socketed terminals are taken under the terminal crimping machine and the press is used to extrude the terminals and the wire core. Since the operation of the press is somewhat dangerous, when the operator places the wire core with the socketed terminal under the punching head, it may easily cause the punching head to press on the operator's hand due to the operator's inattention, with relatively high danger.

[0088] Embodiment 4

[0089] The specific working process of the electrical wiring harness processing and termination equipment of this application includes the following steps:

[0090] Step 1: The device is powered on and in normal working state. The stripped wire harness is placed on the placement slot 511. Then the fixing belt 533 is pulled to select the fixing rod 535 at a suitable position according to the tightness of the fixing of the wire harness and clamp it into the slot on the fixing seat 538.

[0091] Step 2: The terminal receiving seat 103 is in a reset state (i.e., the side close to the positioning plate 101). The electromagnetic lock 221 is first opened to place the wiring harness terminal into the arc-shaped receiving groove on the terminal receiving seat 103. The pressure sensor 3 receives a signal, and the controller turns on the motor 2 105 and the vacuum pump 24. The motor 2 105 drives the shaft 2 104 to reverse, so that the terminal receiving seat 103 moves to the right. When it contacts the positioning plate 2 102, the pressure sensor 2 receives a signal, and the controller turns on the motor 1 111 to drive the shaft 1 to rotate, so that the conveyor belt 11 moves with the wiring harness placement seat 50.

[0092] Step 3: When the harness placement seat 50 moves to the front of the terminal receiving seat 103, the infrared receiving end receives the signal of the infrared transmitting end 1030, the controller turns off the motor 111, the conveyor belt 11 stops rotating, and the cylinder 30 works to push the slide plate 51 backward. When the slide plate 51 slides backward, when the sleeve 52 contacts the terminal receiving seat 103, the slide plate 51 continues to slide backward, and the sleeve 52 contracts, so as to send the harness head into the harness terminal. When the connecting block 504 touches the limit sensor, the cylinder 30 stops working, and the punching machine 23 drives the punching head 231 to press down, and the harness terminal is punched and fixed on the harness head;

[0093] Step 4: After the punching machine 23 is reset, the cylinder 30 is reset immediately, and the reset spring 503 provides the slide plate 51 with the power to slide forward and reset;

[0094] Step 5: The staff will then remove the punched wire harness, and the equipment will continue to punch other wire harnesses according to the above process.

[0095] It should be noted that when the terminal receiving seat 103 resets to the left, the conveyor belt 11 is in a stopped state, and there is no wire harness placement seat 50 on the front side of the distance that the terminal receiving seat 103 slides to the left, so as to ensure the normal operation of the equipment of the present application.

[0096] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: The equipment of the present application reduces the danger of operating the stamping machine by workers, realizes intelligent operation, not only reduces the working intensity of workers but also improves the safety of workers during work.

[0097] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
