Description

Technical Field

[0001] The utility model relates to the technical field of central control physical knob installation, and in particular to a protective film and a film device used for positioning a physical knob of a central control screen. Background Art

[0002] The function of the smart central control knob is to realize discrete control functions and control many electrical appliances, mainly controlling the electrical appliances of the car body, such as lamps, wipers, door locks, electric windows, sunroofs, etc. The switch signals of these electrical appliances are input to the body control module, and the body control module controls the operation of the corresponding electrical appliances directly or through relays. When the user needs to control a certain electrical appliance, the user needs to rotate the smart central control knob to control the operation of a certain electrical appliance, that is, to control a certain electrical appliance through the physical knob installed on the central control screen.

[0003] For example, a Chinese utility model patent (CN202321230814.5) discloses an intelligent central control knob, which belongs to the technical field of intelligent central control knobs, and includes a host, one end of which is fixedly connected to a circular ring, the inner surface of which is provided with an arc groove, the inner surface of which is provided with a pair of symmetrical through grooves, the through grooves being connected to the annular groove, one end of which is provided with a pair of symmetrical slots, a collar is provided inside the host, and a pair of symmetrical rotating blocks are fixedly connected to the surface of the collar. It is provided with a metal knob, a first slider, a second slider, a knob body, a collar, a rotating block and an annular groove. When the metal knob is rotated, the first slider is driven to rotate, so that the second slider drives the knob body and the collar to rotate, and the rotation of the collar drives the rotating block to rotate in the annular groove, thereby realizing the rotation control of the central control knob.

[0004] However, when the inventors implemented this device, they found the following defects: the physical knob is usually installed and attached to the touch screen to achieve an integrated visual effect of the physical knob and the touch screen. However, the surface of the touch screen is often plated with ARAF, wherein AF will greatly reduce the dyne value of the glass surface, thereby affecting the adhesion between the physical knob button and the touch screen. Therefore, the bonding position between the physical knob button and the touch screen should avoid AF plating. Therefore, before plating ARAF, a protective film needs to be attached to the physical knob to avoid this position being covered by ARAF. However, the protective film cannot be effectively and accurately attached to the screen through the clamp, which affects the installation accuracy of the physical knob. Utility Model Content

The lower release film and the anti-foolproof bevel are fitted with the central control screen by the CCD of the film-sticking machine to achieve automatic film sticking, and then the release film is peeled off.

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] As described in the background technology, AF will greatly reduce the dyne value of the glass surface, thereby affecting the adhesion of the physical knob button and the touch screen. Therefore, the bonding position of the physical knob button and the touch screen should avoid AF plating. Therefore, before ARAF plating, a protective film needs to be attached to the physical knob to avoid this position being covered by ARAF. However, the protective film cannot be effectively and accurately attached to the screen through the clamp, which affects the installation accuracy of the physical knob.

The protective film 3 is protected by the upper release film 4, and the lower release film 1 is grasped by a film laminating machine CCD and visually identified and laminated with the central control screen. The corners of the lower release film 1 are aligned with the corners of the central control screen, so that the protective film 3 laminated with the lower release film 1 is also laminated to the positioning point of the physical knob on the central control screen. Therefore, when plating ARAF, it is avoided to plating ARAF at the positioning point of the physical knob, so that the physical knob is better bonded to the central control screen.

[0033] The utility model provides a film-sticking device for a protective film used for positioning a physical knob of a central control screen. After the lower release film 1 and the protective film 3 are laminated to the central control screen by the CCD of a film-sticking machine, a film-sticking fixture seat 5 is controlled by a robotic arm to move to the lower release film 1, and a rolling wheel 6 is pressed onto the lower release film 1. The protective film 3 laminated to the lower release film 1 is rolled and laminated onto the central control screen by the rotating rolling wheel 6, so that the protective film 3 is more closely attached to the central control screen.
