Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Reference Figure 1A watch film applying auxiliary device comprises a base 1, which is in the shape of a rectangular block. A positioning groove 11 matching the shape of a dial is concavely provided on the top surface of the base 1. The dial is accurately positioned on the base 1 by fitting with the groove wall of the positioning groove 11. The display screen of the dial is higher than the top surface of the base 1 for avoidance when applying the film. Slide rails 12 are arranged on the top surface of the base 1 on opposite sides of the positioning groove 11. The two slide rails 12 are arranged in parallel and symmetrically. Each slide rail 12 comprises a horizontal plate 121 standing on the top surface of the base 1 and a first sliding support bar 122 arranged on the top of the horizontal plate 121. The first sliding support bar 122 extends horizontally along the length direction of the horizontal plate 121 and the outer side wall of the first sliding support bar 122 protrudes from the outer side wall of the horizontal plate 121. The distances from the two horizontal plates 121 to the positioning groove 11 are equal.

[0024] Reference Figure 1 , also includes a positioning structure 2, which is arranged on the top surface of the base 1 and between the two slide rails 12, the positioning structure 2 includes a positioning piece 21 and two positioning columns 22, the positioning piece 21 is located on one side of the positioning groove 11 and is inclined, and the high side of the positioning piece 21 is close to the positioning groove 11, the positioning piece 21 is located between the two cross plates 121 and is at the center of the distance between the two cross plates 121, and the two positioning columns 22 are located on the other side of the positioning groove 11, and the mutual connection line of the positioning piece 21 and the two positioning columns 22 forms a triangle, and a supporting protrusion 221 is convexly provided on the side wall of the bottom of the two positioning columns 22, and the edge of the high side of the positioning piece 21 is bent to form a horizontal supporting portion 211, and the top surface of the supporting protrusion 221 is on the same horizontal plane as the top surface of the horizontal supporting portion 211 of the positioning piece 21, and the positioning piece 21 is provided with a slot 212, and a side wall of the slot 212 coincides with the bending line of the horizontal supporting portion 211, and the positioning piece 21 is convexly provided with a positioning protrusion 213 on the side wall of the slot 212.

[0025] When the protective film is produced and shipped, a release film is pasted on the side of the protective film that is in contact with the display screen of the watch dial, and the other side of the protective film is adhered to a fixed position of a positioning film. The positioning structure 2 cooperates with the positioning film to horizontally position the protective film above the display screen of the watch dial and close to the display screen. Specifically, the positioning film is provided with a first positioning hole matching the positioning protrusion 213 and two second positioning holes matching the two positioning columns 22. The positioning film is inserted into the positioning protrusion 213 through the first positioning hole and is respectively inserted into the two positioning columns 22 through the two second positioning holes for positioning. The film is positioned on the base 1, and the horizontal support portion 211 of the positioning piece 21 and the two support protrusions 221 provide stable triangular support for the positioning film, so that the protective film is above the display screen and placed horizontally, and by reasonably setting the height of the horizontal support portion 211 of the positioning piece 21 and the height of the two support protrusions 221, the bonding surface of the protective film is close to the dial display screen and there is a gap between the release film on the protective film and the dial display screen, which makes it easy to tear the release film from the protective film and make the protective film fit onto the dial display screen more quickly when it moves down.

[0026] Reference Figure 1 , also includes a sliding seat 3 and a pressure roller 4, the bottom surface of the sliding seat 3 is concavely provided with two U-shaped grooves 31, the sliding seat 3 is supported by being respectively clamped into the two first sliding support strips 122 through the two U-shaped grooves 31, and the bottom surface of the sliding seat 3 is also concavely provided with a mounting groove 32 between the two U-shaped grooves 31, the pressure roller 4 is arranged in the mounting groove 32 and is rotatably connected to the sliding seat 3, and part of the pressure roller 4 protrudes out of the mounting groove 32, and the length of the pressure roller 4 is set to be greater than the width of the positioning groove 11, and the groove wall of the U-shaped groove 31 is in contact with the outer surface of the first sliding support strip 122 to achieve the limited sliding seat 3 to shake left and right so that the sliding seat 3 is more stable when sliding along the first sliding support strip 122, and the sliding seat 3 is convexly provided with a cylinder 33 on the side walls of the two U-shaped grooves 31, and the cylinder 33 is located on the outer side of the cross plate 121 and the bottom surface of the first sliding support strip 122 The abutment limits the sliding seat 3 to move up and down, further making the sliding of the sliding seat 3 more stable, and when the sliding seat 3 slides on the first sliding support strip 122, the distance between the pressure roller 4 and the bottom of the mounting groove 32 is fixed, so that the distance from the pressure roller 4 to the dial display screen is fixed, and the distance is smaller than the distance from the positioning film to the display screen so that when the pressure roller 4 moves to contact the positioning film, it presses down the positioning film to press the protective film onto the display screen of the dial, and after the protective film fits the display screen of the dial, the pressure roller 4 also applies a certain pressure to the protective film, and in the process of the pressure roller 4 pressing over the protective film, the air between the protective film and the dial display screen is discharged, thereby reducing the generation of bubbles when the display screen of the dial and the protective film are fitted. The length of the pressure roller 4 is set to be greater than the width of the positioning groove 11, which is conducive to covering the protective film. The larger the width of the protective film, the better the fitting effect.

[0027] Furthermore, the material of the pressure roller 4 is an elastomeric material. Since the distance from the pressure roller 4 to the bottom of the positioning groove 11 is smaller than the distance from the positioning film to the bottom of the positioning groove 11, the distance from the horizontal support portion 211 of the positioning sheet 21 to the bottom of the positioning groove 11 is slightly higher than the distance from the pressure roller 4 to the bottom of the positioning groove 11. By utilizing the characteristics of the elastic material that deforms under force, the pressure roller 4 can move through the positioning sheet 21, and the pressure roller 4 made of the elastomeric material is not easy to damage the protective film and the display screen of the dial.

[0028] Reference Figure 1 and Figure 2 Furthermore, the bottom surface of the positioning groove 11 is inclined, so that the display screen of the dial is inclined when the dial is placed in the positioning groove 11, and the inclination direction is from the positioning piece 21 to the direction of the positioning column 22, and the inclination angle is 1°. The moving direction of the pressure roller 4 is from the side of the positioning piece 21 away from the positioning column 22 to the direction of the positioning column 22. Since the dial is inclined, during the movement of the pressure roller 4, the distance from the pressure roller 4 to the bottom of the positioning groove 11 is gradually reduced. The pressure applied to the protective film by the pressure roller 4 during the movement of the pressure roller 4 to press the protective film to the dial display screen gradually increases, and the contact between the pressure roller 4 and the positioning film gradually becomes tighter. The process of the user pushing the sliding seat 3 to move changes from easy to difficult, and it is easier to reset the sliding seat 3 to the starting position, which is convenient for the user to feel the process of pressing the film and have a better experience. At the same time, the pressure applied by the pressure roller 4 to the protective film gradually increases, and the fitting effect of the protective film and the dial is better.

[0029] Reference Figure 1 and Figure 2 Furthermore, each slide rail 12 also includes two second sliding support bars 123 arranged at the two ends of the transverse plate 121. The two second sliding support bars 123 extend along the width direction of the transverse plate 121 and dock with the first sliding support bar 122. The docking points are all rounded transition 124, which is convenient for the sliding seat 3 to slide from the first sliding support bar 122 to the second sliding support bar 123. The sliding seat 3 moves to the second sliding support bar 123 to realize the top of the sliding seat 3 facing the end of the transverse plate 121, which is convenient for reducing the overall height of the device and convenient for storage and carrying. Furthermore, the outer sides of the two transverse plates 121 are respectively connected to the two sides of the rectangular block-shaped base 1 The surfaces are on the same horizontal plane, and the two end surfaces of the horizontal plate 121 are respectively on the same horizontal plane with the two end surfaces of the rectangular block-shaped base 1. The two second sliding support strips 123 arranged at the two ends of the horizontal plate 121 are also extended downward to the two end surfaces of the base 1 respectively. The top surface of the base 1 is concavely provided with a receiving groove 13 for accommodating the sliding seat 3 and the pressure roller 4 at the end close to the positioning piece 21. The sliding seat 3 slides onto the second sliding support strip 123 and is accommodated in the receiving groove 13. This scheme is conducive to reducing the width of the horizontal plate 121 while keeping the sliding seat 3 and the pressure roller 4 of appropriate size, thereby further reducing the overall height of the device and facilitating storage and carrying.

[0030] Reference Figure 1 Furthermore, each first sliding support bar 122 is provided with a notch 1221 for the cylinder 33 to pass through or penetrate, and the notch 1221 is located at one end of the first sliding support bar 122 close to the positioning plate 21. The notch 1221 allows the cylinder 33 to pass through or penetrate, so that the sliding seat 3 can be detached from the slide rail 12.

[0031] Reference Figure 1 Furthermore, a vertical limit strip 1211 is protruded on the outer wall of the horizontal plate 121, and the limit strip 1211 is used to abut against the cylinder 33. When the cylinder 33 is in contact with the limit strip 1211, the center line of the pressure roller 4 coincides with the edge line of the high side of the display screen of the dial. This design reduces the situation in which the pressure roller 4 hits the side of the protective film and causes the protective film to be lifted up when the sliding seat 3 slides in the opposite direction.

[0032] Reference Figure 1 Furthermore, the base 1 is provided with channels 14 for laying the watch strap on the opposite side walls of the positioning groove 11, and the two channels 14 are located between the two slide rails 12. The watch strap can be avoided through the channels 14, and it is more convenient not to separate the watch strap and the dial when applying a film to the watch.
