[0028] Please refer to Figures 1-3 the specific structure of the preferred first embodiment of the utility model, which is a mobile phone middle plate film tearing mechanism, a host 10 that can move up and down, a material sticking mechanism 20 arranged on the host 10 and a traction mechanism 30 that pulls the adhesive member 21 in the material sticking mechanism 20, and the lower end of the host 10 is provided with a pressing station 40 for pressing the workpiece on the pressing carrier 60, the adhesive member 21 passes through the pressing station 40, and the pushing assembly 50 is arranged beside the pressing station 40.

[0029] The pressing station 40 moves down with the host 10 to press the workpiece on the pressing carrier 60, the output end of the pushing assembly 50 moves down in the pressing station 40, and the adhesive surface of the adhesive member 21 is pressed on the film of the workpiece. Compared with the existing mobile phone middle plate film tearing structure, the film tearing roller can rotate and contacts the film on the middle plate to remove the film, but as the number of films torn by the film tearing roller increases, the film is easily wound on the surface of the film tearing roller, resulting in poor film tearing effect. In comparison, when tearing the film, the host 10 moves down, the pressing station 40 pre-presses the workpiece on the carrier 60, then the adhesive surface of the adhesive member 21 is adhered to the film on the workpiece through the movement of the output shaft of the pushing assembly 50, then the host 10 moves up, and the traction mechanism 30 pulls the film away from the workpiece and adheres to the adhesive member 21, and the adhesive surface without the film is moved to below the output shaft of the pushing assembly 50 through the traction of the traction mechanism 30, so as to facilitate the removal of the film on another workpiece.

[0030] As Figure 2 shown, the pressing station 40 includes two first guide plates 41 and second guide plates 42 arranged opposite to each other and installed at the lower end of the host 10, and the pushing assembly 50 moves between the first guide plate 41 and the second guide plate 42. The first guide plate 41 and the second guide plate 42 limit the adhesive member 21 below the pushing assembly 50, so that the adhesive member 21 located between the first guide plate 41 and the second guide plate 42 is in close contact with the film on the workpiece after being pressed by the pushing assembly 50, so as to ensure the film tearing efficiency.

[0031] As Figure 3As shown, the first guide plate 41 and the second guide plate 42 are provided with two opposite rotating rollers 43 at one end of the carrier 60, the adhesive member 21 passes through the rotating rollers 43, and the adhesive member passing through the rotating rollers 43 is located below the pushing assembly 50. In order to avoid the adhesive member 21 being broken due to the bending surface of the first guide plate 41 and the second guide plate 42 pressing the adhesive member 21 when the first guide plate 41 and the second guide plate 42 are pressed down, an opening 44 for the adhesive member 21 to pass through is arranged at the lower part of the first guide plate 41 and the second guide plate 42, and two opposite rotating rollers 43 are arranged at the upper and lower ends of the opening 44, the adhesive member 21 passes through the gap between the two rotating rollers 43, so as to avoid the adhesive member 21 being broken due to pressing during the conveying process and affecting the film tearing efficiency.

[0032] Specifically, the rotating roller 43 is made of rubber, so as to further reduce the probability of the adhesive member 21 being damaged when the film is pressed and torn.

[0033] As shown in the figure, Figure 2 the pushing assembly 50 includes a moving block 51 sliding between the first guide plate 41 and the second guide plate 42, and a first driving cylinder 52 with an output shaft connected to the moving block 51. The first driving cylinder 52 can be a pneumatic cylinder or an electric push rod. The moving block 51 is moved out of the gap between the first guide plate 41 and the second guide plate 42 by the pneumatic cylinder or the electric push rod, and when it is necessary to tear the film on the middle plate of the mobile phone, the moving block 51 is pushed to the film on the middle plate of the mobile phone by the pneumatic cylinder or the electric push rod, so that the adhesive surface of the adhesive member 21 is attached to and adsorbed to the film. Then, the film attached to the adhesive member 21 is separated from the middle plate of the mobile phone by the upward movement of the moving block 51 and the traction of the traction mechanism 30.

[0034] As shown in the figure, Figure 2 the carrier 60 includes a receiving block 61 arranged below the pressing station 40 and the pushing assembly 50, and movable clamping plates 62 arranged on both sides of the receiving block 61, and the opposite surfaces of the two clamping plates 62 are connected with driving members 63. The workpiece is placed on the receiving block 61 and is attached to the film on the middle plate of the mobile phone by the adhesive member 21. In order to avoid the workpiece being separated from the film on it and moving with the adhesive member 21 when the winding column 31 rotates, the movable clamping plates 62 are arranged on both sides of the receiving block 61 to clamp the two side edges of the workpiece, so as to avoid the workpiece being separated from the middle plate carrier 50 during the film tearing.

[0035] Specifically, the driving member 63 can be an electric push rod or a pneumatic push rod, the output shaft of the driving member 63 is connected with the clamping plate 62, and the clamping plate 62 is moved close to / far away from the receiving block 61 by the driving of the driving member 63.

[0036] As shown in the figure, Figure 2 the adhesive member 21 is a tape.

[0037] The material sticking mechanism 20 further comprises a rotatable receiving column 22 arranged on the upper end of the main machine 10 for receiving the adhesive 21. When the adhesive 21 is a transparent tape, the transparent tape can be in the form of a roll and is wound on the receiving column 22. The receiving column 22 is mounted on the main machine 10 through a bearing without any additional driving member. When the traction mechanism 30 is driven, the roll of transparent tape rotates on the receiving column 22 and moves towards the traction mechanism 30.

[0038] The traction mechanism 30 comprises a rotatable winding column 31 arranged on the upper end of the main machine 10 and a plurality of guide columns 32 distributed on the main machine 10. The plurality of guide columns 32 are arranged in the lower part of the main machine 10, and the adhesive 21 is arranged along the plurality of guide columns 32 and passes through the lower end of the pressing station 40. One end of the winding column 31 is connected with the output shaft of a motor mounted in the inner cavity of the main machine 10. The winding column 31 is driven to wind the adhesive 21 by the motor. When the winding column 31 pulls the wound adhesive 21, the adhesive 21 in movement is always below the first guide plate 421 and the second guide plate 422 through the limiting guidance of the plurality of guide columns 32. When the driving cylinder 411 drives the push block 412 to move downward, the adhesive 21 can be pushed to contact and adhere to the film on the product.

[0039] As shown in Figure 1 For example, the side of the main machine 10 away from the material sticking mechanism 20 is provided with a second driving cylinder 11. The output shaft of the second driving cylinder 11 is connected with the processing platform. The main machine 10 can move up and down through the driving of the second driving cylinder 11 to cooperate with the first guide plate 421 and the second guide plate 422 to pre-press the workpiece on the receiving block 61, so as to achieve a better film tearing effect.

[0040] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application. Any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical scheme of the present application.
