Implementation Method

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] See Figures 1 to 3As shown, a card cloth light box soft film installation auxiliary fixture includes an adjustment bracket, the adjustment bracket consists of two telescopic arms 1, the two telescopic arms 1 are cross-arranged and connected by an axle rod 2, the axle rod 2 is located at the intersection of the two telescopic arms 1, a bottom tray 3 is fixed at the upper end of the axle rod 2, the bottom tray 3 is located above the adjustment bracket, and the adjustment bracket is X-shaped, wherein the telescopic arm 1 has a telescopic structure, for example: the telescopic arm 1 consists of a central arm tube 4 and an end arm rod 5, one end of the end arm rod 5 is inserted into the central arm tube 4, and the length of the telescopic arm 1 is adjusted as the end arm rod 5 is inserted into the central arm tube 4 to a depth or shallowness. Two pressure strips are fixed at the end of the central arm tube 4, and the two pressure strips are respectively an upper pressure strip 6 and a lower pressure strip 7. The two pressure strips are arranged vertically and parallel, and guide columns 8 are fixed on the upper pressure strip 6 and the lower pressure strip 7. The column 8 is perpendicular to the pressure strip and is located between the two pressure strips. A long strip-shaped slide groove 9 is provided on the end arm 5. The end of the guide column 8 is located in the slide groove 9, and a threaded hole is provided on the upper pressure strip 6. The threaded push rod 10 is screwed in the threaded hole. When the threaded push rod 10 is tightened, the lower end of the threaded push rod 10 is against the slide groove 9. At this time, the central arm tube 4 and the end arm 5 are locked. A clamp 11 is axially connected at both ends of each telescopic arm 1. When installing the soft film, the light box frame can be placed on the bottom tray 3. At this time, the clamp 11 is located at the corner end of the light box frame. A pressing clamp 12 is connected to the clamp 11. The corner end of the soft film is clamped and positioned by the pressing clamp 12 and the light box frame. After the corner ends of the soft film are clamped and positioned, the soft film is in a flat state, which can facilitate the edge of the soft film to be embedded in the side groove on the frame.

[0025] The above-mentioned chuck 11 includes two frame plates 13, which are arranged vertically. A flat support plate 14 is connected between the two frame plates 13. The flat support plate 14 and the bottom tray 3 on the adjustment bracket are located on the same horizontal plane. When the light box frame is matched with the chuck 11, the two frame plates 13 are both located on the outside of the light box frame. At this time, the corner ends of the light box frame are placed on the flat support plate 14, and the flat support plate 14 is axially connected to the telescopic arm 1, so the angle of the chuck can be flipped. In conjunction with the extension and shortening of the telescopic arm and the angle adjustment between the two telescopic arms 1, it can be suitable for light box frames of different specifications.

[0026] See Figures 4 to 7As shown, a threaded rod 15 is fixed on the chuck 11, and the threaded rod 15 is fixed at the junction of the two frame plates 13. The extension line of the threaded rod 15 is perpendicular to the plane where the flat supporting plate 14 is located. At this time, the threaded rod 15 is arranged vertically and is sleeved with the pressing clamping part 12 on the threaded rod 15. The pressing clamping part 12 is composed of a pressing piece 17, and a circular hole 16 is provided at one end of the pressing piece. The threaded rod 15 passes through the circular hole 16. A vertically extending limiting groove is provided on the threaded rod 15, and a limiting strip 18 is fixed in the circular hole 16 on the pressing piece 17. In this way, the pressing piece 17 can move vertically, but the pressing piece 17 cannot rotate. The pressing clamping part 12 is located above the light box frame, and a locking disk 19 is provided above the pressing clamping part 12. The locking disk 19 is screwed with the threaded rod 15. After the soft film is arranged between the pressing clamping part 12 and the light box frame, the locking disk 19 is tightened. After the pressing clamping part 12 moves downward, it clamps the corner end of the soft film with the light box frame.

[0027] In order to facilitate the embedding of the clamped and positioned soft film into the side groove of the light box frame, a film pushing portion 20 is provided above the clamping portion 12, and the film pushing portion 20 is connected to the threaded rod 15. At this time, the locking disk 19 is located between the film pushing portion 20 and the clamping portion 12. After the locking disk 19 is rotated, the clamping portion 12 can be moved downward. A notch 21 is provided on the pressing plate 17. The notch 21 extends from the other end of the pressing plate 17 to the circular hole 16. After the soft film is clamped, the corner end of the soft film can be pushed into the side groove on the light box frame after the film pushing portion 20 passes through the notch 21.

[0028] The above-mentioned film pushing portion 20 includes a base 22 located above the notch 21, the base 22 is connected to the threaded rod 15 through a flat guide rail, at this time the flat guide rail is in a horizontal state, a vertically arranged push rod 23 passes through the base 22, and a pushing piece 24 is fixed to the lower end of the push rod 23. When the push rod 23 is pushed downward, the pushing piece 24 can be driven to pass through the notch 21 on the pressing piece 17. The pushing piece 24 is composed of two thin sheets, the two thin sheets are vertically connected, and the two thin sheets are perpendicular to the plane where the light box frame is located. The corner end of the soft film is squeezed into the side groove on the light box frame by the pushing piece 24, and a reset mechanism is provided between the push rod 23 and the base 22. Structure, after the corner end of the soft film is pushed into the side groove of the light box frame by the pushing piece 24, the pushing piece 24 and the push rod 23 can be moved upward under the action of the reset structure, so that the pushing piece 24 is separated from the side groove of the light box frame. Specifically, the reset structure includes a reset spring 25 mounted on the push rod 23. The reset spring 25 is a spring that restores the force after compression. The reset spring 25 is located above the base 22. A pressing plate 26 is fixed to the upper end of the push rod 23. After a downward thrust is applied to the pressing plate 26, the distance between the pressing plate 26 and the base 22 becomes smaller. At this time, the reset spring 25 is in a compressed state.

[0029] The base 22 is movably connected to the flat guide rail, and the flat guide rail is parallel to the notch 21, that is, the flat guide rail extends along the length direction of the notch 21, and the flat guide rail is located above the pressing piece 17. When the base 22 is connected to the flat guide rail, a through-hole 27 for passing through the flat guide rail is provided on the base 22, and the flat guide rail passes through the through-hole 27 on the base 22, so that the base 22 can move along the length direction of the notch 21. A threaded locking hole is provided on the base 22, and the threaded locking hole extends downward from the upper surface of the base 22 to be connected to the through-hole 27 on the base 22. A locking rod 28 is screwed into the threaded locking hole. In this way, after the base 22 is slid along the length direction of the flat guide rail until the pushing piece 24 is aligned with the side groove on the light box frame, the position of the base 22 can be locked by screwing the locking rod 28.

[0030] In order to ensure the stability of the base 22, the above-mentioned flat guide rail includes two parallel rails 29. At this time, there are also two through-holes 27 on the base 22. The same side ends of the two rails 29 are connected with positioning arms 30, one of which is fixedly connected to the upper end of the threaded rod 15, and the other positioning arm 30 is connected to the pressing plate 17 through a vertical arm. At this time, the notch 21 on the pressing plate 17 is located between the two rails 29, and the push rod 23 on the base 22 is located between the two rails 29. Through the vertical movement of the push rod 23, the pushing plate 24 can pass through the notch 21 on the pressing plate 17.

[0031] After the corner end of the soft film is connected to the corner end of the light box frame, the soft film is in a flat state, and the edge of the soft film basically corresponds to the edge groove on the light box frame, so the edge of the soft film can be easily squeezed into the edge groove of the light box frame.
