Description

Technical Field

[0001] This utility model belongs to the technical field of film tearing equipment, specifically relating to a film tearing mechanism that can control the film tearing position. Background Technology

[0002] In the production of precision components such as electronic products, optical components, and displays, protective films are widely used on product surfaces to prevent scratches or contamination during transportation or processing. However, the protective film needs to be precisely peeled off before subsequent assembly or use. Traditional film peeling methods mainly rely on manual operation, which has problems such as low efficiency and easy damage to the product surface. Especially for high-precision or large-size products, manual film peeling is difficult to meet the needs of industrial production. Utility Model Content

[0005] This utility model provides a film-tearing mechanism capable of controlling the film-tearing position, including a conveying mechanism, a film-tearing mechanism, a waste material clamping mechanism, and a worktable. The conveying mechanism spans the worktable. The film-tearing mechanism includes a support, a translational linear module, a lifting module, and an adsorption head. The support spans the conveying mechanism and is supported on the worktable. The translational linear module is mounted on the support, and the lifting module is mounted on the translational linear module. The adsorption head is located at the lower end of the lifting module. The waste material clamping mechanism includes a mounting base, a rotating base, a rotary motor, a clamping cylinder, and grippers.

[0024] refer to Figure 1 As shown, this utility model embodiment provides a film-tearing mechanism 2 that can control the film-tearing position, including a conveying mechanism 1, a film-tearing mechanism 2, a waste material clamping mechanism 3, and a worktable 4.

[0025] The conveying mechanism 1 includes a frame 11, a conveyor belt 12, a drive roller 13, a redirecting roller 14, a support roller 15, and a conveyor motor 16. The drive roller 13 and the redirecting roller 14 are rotatably supported at both ends of the frame 11, respectively. The support roller 15 is rotatably supported on the frame 11 and located between the drive roller 13 and the redirecting roller 14. The conveyor belt 12 passes over the drive roller 13 and the redirecting roller 14. The conveyor motor 16 is supported on the frame 11 and is connected to the drive roller 13 via a reducer. The output shaft of the conveyor motor 16 is connected to the input shaft of the reducer via a coupling. The output shaft of the reducer is connected to one end of the drive roller 13 via a coupling. The conveyor motor 16 can drive the drive roller 13 to rotate, thereby driving the conveyor belt 12 to rotate. The rotation of the conveyor belt 12 can convey the material placed on it backward. The support roller 15 supports the upper layer of the conveyor belt 12, ensuring smooth conveying.

[0026] The workbench 4 is a table-type structure and is located at the film-tearing station of the conveying mechanism 1. In this embodiment, the conveying mechanism 1 spans across the workbench 4.

[0027] refer to Figure 2 As shown, the film-tearing mechanism 2 includes a support 21, a translational linear module, a lifting module, and an adsorption head 28.

[0028] The support 21 is a gantry structure, which spans the conveying mechanism 1 and is supported on the workbench 4.

[0029] The translation linear module includes a guide rail 22, a lead screw 23, a nut 24, a translation slide 25, and a translation motor 26. The guide rail 22 is supported on the upper end of the bracket 21. The two ends of the lead screw 23 are rotatably supported on the bracket 21 through bearing seats and are adjacent to the guide rail 22. The nut 24 is threadedly engaged with the lead screw 23. The translation slide 25 is slidably mounted on the guide rail 22 and is also connected to the nut 24. The translation motor 26 is mounted on the bracket 21 and is drivenly connected to one end of the lead screw 23. When the translation motor 26 works, it can drive the lead screw 23 to rotate. The rotation of the lead screw 23 can drive the nut 24 to move along its axial direction, thereby driving the translation slide 25 to move synchronously.

[0030] The lifting module can use a linear motor 27, a lead screw mechanism, or a hydraulic cylinder. In this embodiment, the lifting module uses a linear motor 27, which is mounted on a translation slide 25. The extension rod of the linear motor 27 is perpendicular to the ground. The suction head 28 is located at the lower end of the extension rod of the linear motor 27. The suction head 28 is a vacuum suction head, which is connected to a vacuum generator through an air pipe. Thus, when the linear motor 27 descends, causing the suction head 28 to contact the film of the product to be peeled, the vacuum generator operates, causing the suction head 28 to generate negative pressure to adhere to the film layer. Then, the linear motor 27 rises, driving the suction head 28 to separate the film layer from the product. The translation linear module operates, causing the linear motor 27 and the suction head 28 to move to one side, thereby peeling the film layer off the product.

[0031] refer to Figure 3 As shown, the waste clamping mechanism 3 includes a mounting base 31, a rotating base 32, a rotating motor 33, a clamping cylinder 34, and a gripper 35.

[0032] Mounting base 31 is disposed on the workbench 4 and located on one side of the conveying mechanism 1. Mounting base 31 is adjacent to bracket 21. Rotary motor 33 is disposed on mounting base 31. Rotary seat 32 is disposed on the output shaft of rotary motor 33. Clamping cylinder 34 is disposed on rotating seat 32. Clamping jaw 35 is disposed on the gripper of clamping cylinder 34. Clamping cylinder 34 is connected to air generator through air pipe. When film tearing mechanism 2 tears the film from the product, it moves above waste clamping mechanism. Rotary motor 33 drives rotating seat 32 and drives clamping cylinder 34 to rotate, so that gripper 35 contacts film on adsorption head 28. Then air generator controls clamping cylinder 34 to drive gripper 35 to clamp film, thereby removing film from adsorption head 28.

[0033] The workbench 4 has a material discharge port on its surface, which is adjacent to the waste material clamping mechanism. Below the material discharge port is a waste material collection box 5. After the gripper 35 is released, the film layer it holds can fall from the material discharge port into the waste material collection box 5 for convenient centralized processing.

[0034] Multiple baffles 17 can be installed along the conveying direction of the conveying mechanism 1. The baffles 17 are supported on one side of the frame 11 by a baffle motor 18. The baffle motor 18 can drive the baffles 17 to rotate to a horizontal position. At this time, the baffles 17 are horizontal above the conveyor belt 12, which can block the conveyed items. When the baffle motor 18 drives the baffles 17 to rotate to a vertical position, the items on the conveyor belt 12 will be conveyed forward. One baffle 17 is set at the film-tearing station, and at least one baffle 17 is set on the conveyor line in front of the film-tearing station. The baffles 17 can intercept and stop the conveyed workpiece from moving forward, which can better ensure the smooth operation of the conveying and film-tearing work.

[0035] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
