Technical Field

[0001] This utility model belongs to the technical field of film pressing mechanism, and more specifically, relates to a mobile phone film pressing and venting mechanism. Background Technology

[0002] To protect smartphone screens, a screen protector is usually applied. However, most screen protectors applied by factory equipment tend to produce air bubbles, resulting in a high defect rate. Removing these air bubbles manually is troublesome and incomplete. Summary of the Invention

[0003] The main purpose of this utility model is to provide a mobile phone film pressing and venting mechanism that can completely expel air bubbles after the mobile phone film is applied, with high efficiency and low defect rate.

[0005] In a specific embodiment of this utility model, lifting adjustment components are provided on both sides of the lifting plate, and the two ends of the roller are respectively connected to the two lifting adjustment components.

[0006] In a specific embodiment of this utility model, the lifting adjustment assembly includes a linear bearing and a connecting member. The linear bearing has a guide shaft inside, one end of the guide shaft is fitted with a spring and is fixedly connected to one end of the connecting member, and the other end of the connecting member is movably connected to a roller.

[0007] In a specific embodiment of this utility model, a reserved hole is provided on the fixing plate, and the inner diameter of the reserved hole is larger than the top outer diameter of the linear bearing.

[0008] In a specific embodiment of this utility model, mounting holes are symmetrically provided on the fixing plate, and bearing guide sleeves are fixedly provided on the mounting holes. The two bearing guide sleeves are respectively provided on both sides of the motor.

[0009] In a specific embodiment of this utility model, two guide rods are fixedly connected to the top of the lifting plate, and the two guide rods are movably disposed within the bearing guide sleeve.

[0010] In a specific embodiment of this utility model, a sensing bracket is fixedly connected to one side of the fixed plate, two photoelectric sensors are spaced apart on the sensing bracket, and a sensing sheet that cooperates with the photoelectric sensor is provided on the side of the lifting plate near the photoelectric sensor.

[0012] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects: This mobile phone film pressing and venting mechanism uses a motor to drive a screw to rotate, causing the lifting plate to move back and forth within a limited range without disengaging from the screw. The rollers follow the lifting plate downwards, contacting the mobile phone film to expel air bubbles. After the air bubbles are expelled, the rollers follow the lifting plate upwards to wait for the next mobile phone film to be processed. This mechanism can effectively reduce labor costs, thoroughly remove air bubbles, reduce the defect rate, and is highly efficient. Attached Figure Description

[0019] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0020] Reference Figures 1 to 3 As shown, a mobile phone membrane pressing and venting mechanism is provided, including a fixed plate 1, a motor 2 fixedly installed on the top of the fixed plate 1, a screw 3 connected to the output end of the motor 2, a movable lifting plate 4 provided at the bottom of the fixed plate 1, a roller 43 provided at the bottom of the lifting plate 4, and a threaded hole 41 opened on the lifting plate 4, which is threadedly connected to the end of the screw 3 away from the motor 2.

[0021] In this embodiment, the phone with a screen protector is moved under the roller 43, the motor 2 is started to drive the screw 3, causing the lifting plate 4 to move downwards, and the roller 43 presses down onto the screen protector and contacts it. Then the phone is moved so that the roller 43 rolls from one side of the screen protector to the other, thereby expelling air bubbles. The lifting plate 4 can only move within a limited range and the screw 3 is long enough to prevent the screw 3 from disengaging from the threaded hole 41. The screw 3 is connected to the motor 2 through a coupling.

[0022] In one embodiment of this utility model, lifting adjustment components 44 are provided on both sides of the lifting plate 4, and the two ends of the roller 43 are respectively connected to the two lifting adjustment components 44.

[0023] Furthermore, the lifting adjustment assembly 44 includes a linear bearing 441 and a connector 442. The linear bearing 441 is provided with a guide shaft. One end of the guide shaft is fitted with a spring and is fixedly connected to one end of the connector 442. The other end of the connector 442 is movably connected to the roller 43.

[0024] In this embodiment, the motor 2 drives the roller 43 to move downwards and contact the mobile phone. The spring is compressed, and the guide shaft inside the two linear bearings 441 extends out of the top plane of the linear bearing 411. At a certain position, the roller 43 contacts and rolls the mobile phone film on the mobile phone to better roll and vent air.

[0025] In one embodiment of this utility model, a reserved hole 14 is provided on the fixed plate 1. The inner diameter of the reserved hole 14 is larger than the outer diameter of the top of the linear bearing 441. Since the top of the linear bearing 441 protrudes outward from the top surface of the lifting plate 4, the top of the linear bearing 441 is prevented from hitting the bottom of the fixed plate 1 when the lifting plate 4 rises. Therefore, a reserved hole 14 is provided at the corresponding position of the fixed plate 1 to prevent the top of the linear bearing 441 from hitting the bottom of the fixed plate 1. The top of the linear bearing 441 can pass through the reserved hole 14.

[0026] In one embodiment of this utility model, mounting holes 11 are symmetrically provided on the fixing plate 1, and bearing guide sleeves 12 are fixedly provided on the mounting holes 11. The two bearing guide sleeves 12 are respectively provided on both sides of the motor 2.

[0027] Furthermore, two guide rods 42 are fixedly connected to the top of the lifting plate 4, and the two guide rods 42 are movably arranged inside the bearing guide sleeve 12.

[0028] In this embodiment, the two guide rods 42 are respectively inserted into the corresponding bearing guide sleeves 12 to play a guiding role.

[0029] In one embodiment of this utility model, a sensing bracket 5 is fixedly connected to one side of the fixed plate 1, and two photoelectric sensors 51 are spaced apart on the sensing bracket 5. A sensing sheet 52 that cooperates with the photoelectric sensor 51 is provided on the side of the lifting plate 4 near the photoelectric sensor 51.

[0030] Furthermore, fixing blocks 13 are fixedly connected to both sides of the top of the fixing plate 1, and the sensing bracket 5 is fixedly mounted on one of the fixing blocks 13. Preferably, the fixing block 13 is provided with several assembly holes 131 to facilitate the installation of the entire mechanism.

[0031] In this embodiment, the range of motion of the lifting plate 4 is the distance between the two photoelectric sensors 51. When the lifting plate 4 descends, the lower photoelectric sensor 51 immediately shuts off the motor 2 when it senses the sensing plate 52. When the lifting plate 4 rises, the upper photoelectric sensor 51 also immediately shuts off the motor 2 when it senses the sensing plate 52. This can effectively prevent the lifting plate 4 from disengaging from the threaded hole 41 and prevent it from falling out.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
