Description

Technical Field

[0001] The present invention relates to the technical field of vehicle sun visor makeup mirrors, and particularly to a high-frequency hot pressing and punching process for a new type of makeup mirror cover of a vehicle sun visor. Background Art

[0002] A sun visor makeup mirror refers to a makeup mirror installed in the sun visor in front of the heads of the driver and the co-driver. Generally, only the co-driver side has this configuration in ordinary vehicle models, while both sides have it in high-class vehicle models, and are equipped with lighting lamps, which automatically turn on when the mirror cover is opened and automatically turn off when the mirror cover is closed.

[0003] The conventional injection-molded outer shell or mirror cover has a relatively hard feel, and the baffle that slides left and right needs to store and hide the baffle, resulting in a relatively small mirror surface area. Therefore, a high-frequency hot pressing and punching process for a new type of makeup mirror cover of a vehicle sun visor needs to be proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-frequency hot pressing and punching process for a new type of makeup mirror cover of a vehicle sun visor to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A high-frequency hot pressing and punching process for a new type of makeup mirror cover of a vehicle sun visor. The new type of makeup mirror of the vehicle sun visor includes a mirror cover fabric with an adhesive film. The specific high-frequency hot pressing and punching process steps of the new type of makeup mirror of the vehicle sun visor are as follows:

[0006] Step 1: Place the first resin sheet, the second resin sheet, and the third resin sheet as shown in the figure. Install the first mirror cover locking magnet in the square holes of the first resin sheet and the third resin sheet, install the second mirror cover locking magnet in the square hole of the second resin sheet, and the magnetic poles correspond as shown in the figure. For the circular mirror cover induction magnet in the middle of the second resin sheet, there is no magnetic pole requirement. Fix all the magnets with transparent tape, and it is necessary to fix and paste around the resin sheet in a whole circle.

[0007] Step 2: Power on the high-frequency hot pressing and punching turntable machine and heat it up to 95°C. Place a piece of fabric on the bottom mold, place the three resin sheets with installed magnets in sequence according to the figure, cover a piece of fabric, rotate and operate the equipment for hot pressing and closing the mouth, rotate and operate the equipment for punching the outer shape of the mirror cover, check the appearance, and place it on the transfer table to the welding mirror cover station.

[0008] Step 3: Turn on the circuit board welding machine and heat it up to 145°C. Assemble the lamp bottom plate and the lamp circuit board corresponding to the positioning posts, place it in the inspection station to verify that the lamp beads emit light normally, and press the two green buttons at the same time to complete the hot melting.

[0009] Step 4: Install a locking magnet at the corresponding position of the makeup mirror assembly, and tear off the four-sided double-sided adhesive diamond-shaped paper of the makeup mirror assembly; align and stick it on the lamp bottom plate, press it tightly, power on the mirror surface laminating machine, put the lamp bottom plate with the light guide plate installed into the outer mold and tear off the static film, tear off the double-sided adhesive diamond-shaped paper on the back of the mirror, put the mirror surface into the inner mold, and use an electrostatic gun to blow the light guide plate surface to remove dust. Press the two green buttons to complete the lamination, and put it on the external inspection table to check for dark shadows, black dots, light leakage, etc.;

[0010] Step 5: Start the machine and heat up to 170 degrees; put the lens into the bottom mold, align the lens cover with the four lens hot melt post holes and place it on the sponge; press the two green buttons to complete the hot melt; start the equipment, and it can work when hearing a harsh sound. After hot melting, the lens is installed in the bottom mold, the pressing pliers are pressed tightly, and the lens cover is sucked on the iron plate in front; press the two green buttons to complete the welding;

[0011] Step 6: After the product passes the self-inspection, confirm whether the product packaging is intact and whether the product quantity meets the boxing requirements; for small plastic turnover box B1, there are 100 in each box, 2 in each 320*250 foam bag, and 50 bags; for the temporary packaging plan, since the mirror surface is fragile, it is not stacked for shipment temporarily.

[0012] Preferably, a first resin sheet, a second resin sheet, and a third resin sheet are respectively adhered to the glue film on the lens cover fabric. A first lens cover locking magnet is installed on the first resin sheet and the third resin sheet, a second lens cover locking magnet is installed on the second resin sheet, and a lens cover induction magnet is adhered in front of the second resin sheet.

[0013] Preferably, the first lens cover locking magnet has its "N" pole facing forward, and the second lens cover locking magnet has its "S" pole facing forward.

[0014] Preferably, there is no magnetic pole requirement for the circular lens cover induction magnet in the middle of the second resin sheet.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This new type of high-frequency hot pressing and die-cutting process for the makeup mirror lens cover of a vehicle-mounted sun visor replaces the conventional hard plastic shell with genuine leather or imitation leather fabric for processing. The fabric evenly seals the resin sheet to achieve the folding function. It is changed from traditional injection molding to fabric heat sealing. The conventional injection-molded shell or lens cover feels hard. The new fabric improves the softness and comfort of the hand feeling. Encapsulating the resin sheet increases the folding function, making the lens cover shrink in the open state to prevent the line of sight from being blocked. The fabric is compounded with a back adhesive. The high-frequency process activates the back adhesive at a fixed temperature to bond the upper and lower fabrics, and at the same time encapsulates the resin sheet, and then die-cuts to cut out the required lens cover shape. The application of high-frequency heat sealing increases the encapsulation function of the fabric, realizes the built-in magnetic switch, and diversifies the folding function. Changing the shape of the die-cutting mold can diversify the appearance of the lens cover and improve the aesthetic effect;

[0017] 2. The novel high-frequency hot pressing and punching process for the makeup mirror cover of a vehicle-mounted sun visor uses an electric turntable to automatically transfer workstations for the high-frequency hot pressing and punching processes. The turntable is provided with multiple lower dies to cooperate with the two-station upper die to complete automatic production. The high-frequency heat sealing and punching processes are integrated on the loading machine, which can greatly improve production efficiency, meet the demand for large-scale supply, and significantly reduce manufacturing costs.
