Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness manufacturing technology, specifically a novel air knife blowing static electricity removal device. Background Technology
[0002] Coaxial cable harness manufacturing typically involves wrapping the conductor with an inner insulating tube, then wrapping the inner insulating tube with a braided layer, and finally wrapping the braided layer with an outer insulating tube. During production, a wire stripping process is performed, which involves cutting off a portion of the outer insulating tube and the braided layer at one end of the cable harness. In addition to protecting the conductor from being cut, the braided layer also serves to shield against external electromagnetic interference to prevent interference with signals inside the conductor. After the braided layer is cut, a large amount of residue remains. This residue, mixed with dust, can adhere to the cable harness, causing contamination and negatively impacting subsequent production. Currently, most manufacturers use manual cleaning of the braided layer residue, which is time-consuming, labor-intensive, and prone to generating static electricity. Utility Model Content

[0005] The display screen operating device includes a display screen mounted on the front of the outer cover, and a power switch, an on button, and an off button mounted on the outer cover are provided below the display screen.
[0006] The decontamination and static electricity removal device includes a frame mounted on an outer cover, on which air knife supports and static eliminator supports are installed. An air knife is installed on the air knife support, and a static eliminator is installed on the static eliminator support. An air nozzle is installed on one side of the frame and is connected to the air knife.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5 This utility model provides a technical solution: a novel air knife blowing static electricity removal device, including an outer cover 4, on which a display screen operation device 1, a decontamination and static electricity removal device 2 and an electrical control device 3 are provided;
[0021] The display screen operation device 1 includes a display screen 11 mounted on the front of the outer cover 4, and a power switch 12, an on button 13 and an off button 14 mounted on the outer cover 4 are provided below the display screen 11.
[0022] The decontamination and static electricity removal device 2 includes a frame 22 mounted on an outer cover 4. An air knife support 24 and a static eliminator support 27 are mounted on the frame 22. An air knife 23 is mounted on the air knife support 24, and a static eliminator 26 is mounted on the static eliminator support 27. An air nozzle 25 is mounted on one side of the frame 22 and is connected to the air knife 23.
[0023] This invention employs two start-up methods: pressing the start button or connecting a foot pedal switch to the foot pedal switch socket can start the machine. It only requires a small amount of compressed air to generate a powerful airflow to blow away dirt, and the static eliminator uses plasma to eliminate static electricity. The equipment is simple to operate. This invention replaces the traditional manual operation method and can efficiently remove dirt and static electricity.
[0024] In this utility model, a three-core power socket 5, a foot pedal switch socket 6, and an air inlet 7 are provided on one side of the outer cover 4.
[0025] In this utility model, circular foot pads 21 are installed at the four corners of the bottom of the frame 22.
[0026] In this invention, the air knife 23 and the static eliminator 26 are located on both sides of the frame 22, respectively.
[0027] In this invention, the display screen 11 is tilted for easier operation and observation.
[0028] This invention features two start-up methods: pressing the start button after turning on the power switch, or connecting a foot pedal switch to the external foot pedal switch socket. The machine is started manually by inserting the stripped wire ends (residual braided mesh) through the 3C-air knife. A small amount of compressed air enters the air knife through the nozzle and is blown out at high speed through a thin, 0.05 mm thick sheet of air. Utilizing the Coanda effect and the air knife's unique geometry, this thin air curtain amplifies ambient air 30-40 times within the air knife ring, forming a thin, high-intensity, high-airflow, uniform conical air curtain. This effectively removes contaminants from the product surface passing through the air knife ring, providing cooling and drying in all directions. Simultaneously, the static eliminator removes static electricity from the product using plasma. This process takes 10-15 seconds. After completion, the product is removed. The process is finished. For extended standby or to stop operation, the shut-off button can be pressed. This saves energy, is simple to operate, fast, and efficient, making it the ideal alternative to manual removal of braided layer residue.
