Description

Technical Field

[0001] The present invention relates to the technical field of glue coating, and in particular to a velvet gluing process and a gluing machine for a wiring harness of a new energy vehicle. Background Art

[0002] The "gluing" process of the velvet used in the wiring harness of new energy vehicles before shaping refers to applying shaping glue on the surface of the velvet base material. It is a key pretreatment process for the velvet used in the wiring harness, which directly affects the strength, temperature resistance and noise reduction performance of the velvet tape. The velvet will be heat-set after being glued. After the glue is dry, a shaping layer is formed on the glue side of the velvet, which is convenient for attaching adhesive glue to the shaping layer again to play a bonding role, while the other side of the velvet remains in the shape of velvet.

[0003] When using polyester non-woven fabric or polyamide flannel as the substrate, ensure that the surface is clean and free of impurities to avoid affecting the adhesion of the adhesive. The substrate selection must match the application scenario: polyester flannel has a temperature resistance of 105°C, and polyamide flannel suitable for high-voltage battery areas has a temperature resistance of up to 150°C.

[0004] The existing glue application method generally uses a pair of rollers, one of which applies glue and the other does not. When the velvet passes between the pair of rollers, the velvet will deform. During the deformation, the glue will simultaneously penetrate into the interior of the velvet. When the velvet leaves the pair of rollers, the velvet will expand and reset again, so that the glue that originally penetrated into the interior of the velvet is carried deep into the velvet. This glue is actually wasted meaninglessly. In order to ensure that the surface of the velvet is shaped and that there is still enough glue on the surface after the velvet expands and resets, more glue needs to be applied. The velvet coated with glue will then be heat-set. The existing glue application method is difficult to control the depth of immersion in the velvet, and a large amount of glue is used.

[0014] The process of gluing velvet cloth for wiring harnesses of new energy vehicles uses a gluing machine for gluing velvet cloth for wiring harnesses of new energy vehicles, including the following steps:

[0015] S1: Glue supply system is filled with glue;

[0016] S2: The upper and lower clamping systems of the velvet cloth and the anilox roller system are turned on and rotated. The glue is carried by the anilox roller system to the lower clamping system of the velvet cloth, and the velvet cloth passes between the upper and lower clamping systems of the velvet cloth.

[0017] S3: The air pressure device on the back of the glue blows air, pushing the glue in the velvet to the surface of the velvet. The glue on the velvet is intercepted by the glue retention protrusion to prevent it from dripping. The fluctuation cam rotates and drives the pressure fluctuation plate to swing up and down, realizing the vibration of the velvet, which facilitates the glue to concentrate on the surface.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The upper clamping system and the lower clamping system of the velvet are installed on the frame relative to each other, and are used to clamp and convey the velvet, and press the glue carried by the lower clamping system of the velvet into the velvet. The glue supply system is installed on the frame to supply glue, the anilox roller system is installed on the frame, and the anilox roller system is installed on the glue supply system. The anilox roller system carries the glue in the glue supply system out, and the lower clamping system of the velvet and the anilox roller system are fitted together to realize the conveying of glue. The scraper system is installed on the frame, and the scraper system slides with the surface of the anilox roller system to control the thickness of the glue.

[0020] The glue thickness control system includes a glue side air pressure device and a glue back side air pressure device.

[0021] The glue side air pressure device is provided with a pressure fluctuation plate, a pressure fluctuation control plate and a fluctuation cam. The pressure fluctuation plate and the pressure fluctuation control plate can be slidably installed on the glue side air pressure device. The pressure fluctuation plate and the pressure fluctuation control plate are arranged opposite to each other. When the pressure fluctuation plate is fully pushed into the glue side air pressure device, the pressure fluctuation plate extends to the inner side of the glue side air pressure device. In this way, when the fluctuation cam rotates, the pressure fluctuation plate swings up and down to realize the vibration of the velvet, so that the glue is re-concentrated on the surface of the velvet, thereby ensuring the strength of the surface of the velvet and reducing the amount of glue used.

[0022] When the pressure fluctuation control plate is pushed into the glue side air pressure device, the pressure fluctuation plate is retracted from the glue side air pressure device.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] like Figure 1 — Figure 11As shown, this embodiment provides a flannel laminating machine for new energy vehicle wiring harnesses, including a frame 1, a flannel upper clamping system 2, a flannel lower clamping system 3, an anilox roller system 4, a glue supply system 5, a scraper system 6 and a glue thickness control system 7. The flannel upper clamping system 2 and the flannel lower clamping system 3 are installed on the frame 1 relative to each other up and down, for clamping and conveying the flannel, and pressing the glue carried by the flannel lower clamping system 3 into the flannel, the glue supply system 5 is installed on the frame 1 for supplying glue, the anilox roller system 4 is installed on the frame 1, and the anilox roller system 4 is installed on the upper side of the glue supply system 5, the anilox roller system 4 carries out the glue in the glue supply system 5, the flannel lower clamping system 3 and the anilox roller system 4 are fitted together to realize the conveying of glue, the scraper system 6 is installed on the frame 1, and the scraper system 6 slides with the surface of the anilox roller system 4 to control the thickness of the glue.

[0048] The glue thickness control system 7 includes a glue side air pressure device 72 and a glue back side air pressure device 71. The glue side air pressure device 72 and the glue back side air pressure device 71 are arranged relative to each other. The glue side air pressure device 72 is provided with a glue retention protrusion 721 on the side close to the glue back side air pressure device 71. The glue retention protrusion 721 is arranged on the side of the glue side air pressure device 72 away from the anilox roller system 4. The glue side air pressure device 72 is connected with a glue side air pipe, and the glue back side air pressure device 71 is connected with a glue back side air pipe. The glue back side air pressure device 71 blows air to one side of the glue side air pressure device 72 to make the velvet The glue in the cloth is pushed toward the glue-side air pressure device 72. When the flannel with glue passes through, the glue retaining protrusion 721 lifts the flannel, so that a gap is formed between the flannel and the glue-side air pressure device 72. Since the glue is concentrated on the side of the flannel close to the glue-side air pressure device 72, the gap between the flannel and the glue-side air pressure device 72 is filled with glue. When the flannel is separated from the glue in the gap, this part of the glue will cause the surface of the flannel to be enriched with glue, and the glue that cannot be accommodated in the gap is accommodated by the glue-side air pressure device 72, waiting to be reused, saving glue and enriching the glue on the surface.

[0049] The glue side air pressure device 72 is provided with a pressure fluctuation plate 722, a pressure fluctuation control plate 723 and a fluctuation cam 725. The pressure fluctuation plate 722 and the pressure fluctuation control plate 723 can be slidably mounted on the glue side air pressure device 72. The pressure fluctuation plate 722 and the pressure fluctuation control plate 723 are arranged opposite to each other. When the pressure fluctuation plate 722 is fully pushed into the glue side air pressure device 72, the pressure fluctuation plate 722 extends to the inner side edge of the glue side air pressure device 72. In this way, when the fluctuation cam 725 rotates, the pressure fluctuation plate 722 swings up and down. Since the pressure fluctuation plate 722 has extended to the inner side edge of the glue side air pressure device 72, when the pressure fluctuation plate 722 swings up and down, the air pressure in the glue side air pressure device 72 changes periodically, periodically pushing the velvet, thereby realizing the vibration of the velvet. Under the action of vibration and the gravity of the glue itself, the glue is re-concentrated on the surface of the velvet, ensuring the strength of the surface of the velvet, and on the other hand, reducing the amount of glue used.

[0050] When the pressure fluctuation control piece 723 is pushed into the glue side air pressure device 72, the pressure fluctuation piece 722 is retracted from the glue side air pressure device 72. At this time, when the glue side air pressure device 72 and the glue back side air pressure device 71 are ventilated, the pressure fluctuation piece 722 will bend. Since the pressure fluctuation control piece 723 is thin, the air flow passes through. The fluctuation cam 725 is rotatably installed on the glue side air pressure device 72. The pressure fluctuation piece 722 is transmission-connected with the fluctuation cam 725. The pressure fluctuation piece 722 is elastic. When the fluctuation cam 725 drives the pressure fluctuation piece 722 to vibrate, the flannel vibrates, which facilitates the movement of the glue in the flannel. It is worth noting that if the glue side air pressure device If the air suction of the device 72, the air blowing of the glue back side air pressure device 71 and the rotation of the waving cam 725 occur simultaneously, the degree of glue recovery is high. If only the air blowing of the glue back side air pressure device 71 and the rotation of the waving cam 725 occur simultaneously, the degree of glue recovery will be reduced. If only the air pressure device 71 on the glue back side blows, the degree of glue recovery will be even smaller. The user can adjust it as needed. If the glue side air pressure device 72 blows and the air pressure device 71 on the glue back side suctions, the laminating machine can be capable of blowing materials deep into the flannel. The materials that need to be blown deep into the flannel can be flame retardants or anti-leakage insulating sprays, etc., which makes the laminating machine have rich functions.
