[0066] In this embodiment, a clamping assembly for clamping electronic products is installed on the workbench 3, and the clamping assembly includes:

[0067] The rear positioning plate 4 is fixed horizontally on the workbench 3 and can be fixed in an integrated manner;

[0068] Two vertical side positioning plates 6 are symmetrically arranged and slidably connected to the rear positioning plate 4. A slot for the rear positioning plate 4 to be inserted can be provided on the side positioning plates 6;

[0069] An elastic connecting rod 5 is connected between each side positioning plate 6 and the workbench 3. One end of the elastic connecting rod 5 is fixedly connected to the mounting shaft 14 on the workbench 3 near the end of the rear positioning plate 4. The mounting shaft 14 is rotatably connected to the workbench 3. The other end of the elastic connecting rod 5 is fixed with a pin 12, which can be fixed in an integrated manner. The side positioning plate 6 is provided with a movable groove 13 along its length for the pin 12 to be inserted and moved;

[0070] An L-shaped plate 7 is inserted into the movable groove 13 from one end of the side positioning plate 6 away from the rear positioning plate 4 and is hinged to the pin 12. A front positioning plate 9 is installed on the L-shaped plate 7. The front positioning plate 9 is in an inverted L shape. The long side of the front positioning plate 9 is in contact with the inner wall of the side positioning plate 6.

A forward and reverse motor is fixed inside the workbench 3, and the output shaft of the forward and reverse motor drives and connects to a mounting shaft 14.

[0074] It should be explained that by starting the stepper motor, the stepper motor drives a gear 141 to rotate, and this gear 141 drives another gear 141 to rotate through the double-sided rack 2. The rotation directions of the two gears 141 are opposite, such as Figure 2-3As shown, when the left gear 141 rotates counterclockwise and the right gear 141 rotates clockwise, the elastic connecting rod 5 is driven to rotate via the mounting shaft 14. The two elastic connecting rods 5 drive the two side positioning plates 6 to approach the electronic product and gradually tighten them via the pin shaft 12. At the same time, the elastic connecting rod 5 pulls the L-shaped plate 7 toward the electronic product via the pin shaft 12. The L-shaped plate 7 drives the front positioning plate 9 to push the front positioning belt 10 to fit the electronic product. As a result, the rear positioning plate 4, the side positioning plates 6 and the front positioning belt 10 are tightly attached to the side of the electronic product, and electronic products of different sizes can be clamped.

[0075] It can be understood that the clamping assembly is used to fix electronic products of different sizes on the one hand, and on the other hand to protect the sides of the electronic products to prevent liquid glue material from being sprayed onto the screen and then flowing to the sides of the electronic products, affecting the appearance and use of the electronic products.

[0076] Example 2

[0077] This embodiment is based on embodiment 1. Figure 4-Figure 7 As shown, it also includes a coating component for applying anti-fingerprint oil to the film surface, and the coating component includes:

[0078] The fifth motor 32 is fixed on the workbench 3 and is located behind the rear positioning plate 4. It can be fixed by bolts. A horizontal mounting plate 24 is fixed to the output shaft of the fifth motor 32 and can be fixed by welding.

[0079] A flat film 28 is provided below the mounting plate 24. The four corners of the flat film 28 are respectively fixed to the telescopic ends of the side electric push rod 25 and can be fixed by glue. The side electric push rod 25 is vertically fixed to the mounting plate 24 and can be fixed by screws. An arc-shaped film 27 is integrally connected to the middle position of the flat film 28. A sponge strip is provided inside the arc-shaped film 27 for absorbing anti-fingerprint oil. A slit is provided on the flat film 28 within the range of the arc-shaped film 27. A pressure plate 29 is provided above the arc-shaped film 27. The pressure plate 29 is fixed to the telescopic end of the middle electric push rod 26 and can be fixed by glue. The middle electric push rod 26 is vertically fixed to the mounting plate 24.

[0080] An oil storage box 31 is provided in the housing 1 on one side of the workbench 3 for containing anti-fingerprint oil;

[0081] An air cavity is provided in the mounting plate 24 , and air jet holes connected to the air cavity are evenly provided on the lower surface of the mounting plate 24 . A fan 30 is installed on the top of the mounting plate 24 and can be installed by bolts. The air outlet of the fan 30 is connected to the air cavity.

[0082] After the liquid glue material is sprayed and cured, the fifth motor 32 is started to drive the mounting plate 24 to rotate above the electronic product, and then the middle electric push rod 26 is extended, pressing the arc film 27 and the sponge strip to fit the electronic product screen. At the same time, the slit is opened, and the anti-fingerprint oil in the sponge strip flows through the slit to the electronic product screen. Then the side electric push rod 25 is extended to fit the flat film 28 to the electronic product screen, and at the same time the fan 30 is started. The fan 30 sends air into the air cavity and then sprays it out from the air outlet, blowing towards the flat film 28, so that the flat film 28 is in contact with the electronic product screen. The screen fits more tightly, and the anti-fingerprint oil is fully and evenly applied to the screen of the electronic product through the flat film 28. There is no need for manual application, which avoids uneven manual application or application marks. After the application is completed, the fifth motor 32 can drive the mounting plate 24 to rotate 180 degrees to above the oil storage box 31, and the middle electric push rod 26 and the side electric push rod 25 are extended together to above the anti-fingerprint oil surface in the oil storage box 31, and then the middle electric push rod 26 continues to extend, the slit is opened, and the sponge strip contacts with the anti-fingerprint oil and absorbs the anti-fingerprint oil to prepare for subsequent application.

[0083] In summary, the present invention provides a spray-type automatic film-sticking device for electronic products, the working principle of which is as follows:

[0084] After placing the electronic products, start the stepper motor, which drives a gear 141 to rotate. This gear 141 drives another gear 141 to rotate through the double-sided rack 2. The rotation directions of the two gears 141 are opposite. Figure 2-3 As shown, when the gear 141 on the left rotates counterclockwise and the gear 141 on the right rotates clockwise, the elastic connecting rod 5 is driven to rotate through the mounting shaft 14, and the two elastic connecting rods 5 drive the two side positioning plates 6 to approach the electronic product through the pin shaft 12 and gradually tighten. At the same time, the elastic connecting rod 5 pulls the L-shaped plate 7 to approach the electronic product through the pin shaft 12, and the L-shaped plate 7 drives the front positioning plate 9 to push the front positioning belt 10 to fit the electronic product, thereby closely adhering to the side of the electronic product through the rear positioning plate 4, the side positioning plate 6 and the front positioning belt 10. The feeding unit is used to supply liquid glue material to the nozzle 17 component, and then the liquid glue material is sprayed out in a mist or dot shape through the nozzle 17 component. At the same time, the feeding component drives the nozzle 17 component and / or the workbench 3 to move in the X, Y, and Z directions, and evenly sprays the screen of the electronic product. The liquid glue material naturally levels, and at the same time, the fourth motor is started, and the fourth motor drives the disc 20 to rotate. The disc 20 drives the boss to rotate, and the boss moves in the through groove and drives the mounting rod 19 to swing back and forth. The mounting rod 19 drives the curing lamp 18 to swing back and forth, expanding the motion range and angle of the curing lamp 18 and improving the curing effect. Finally, anti-fingerprint oil is applied through the smearing component, and the protective film can be automatically sprayed to avoid manual film errors, bubbles, fragmentation and other problems. The film shop does not need to have stock, and different mobile phone models and sizes can be filmed.
