Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly, in particular to a quick film tearing mechanism. Background Art

[0002] Mobile phones are one of the most important end products in the information electronics sector, enjoying a vast market. Therefore, mobile phone manufacturing is also one of the most important manufacturing sectors within this sector. After the various components of a mobile phone are processed, they must be assembled to form the final product. The assembly process for other 3C handheld products is similar to that of mobile phones.

[0003] Before assembling different parts, their mounting interfaces need to be covered with protective films to prevent oxidation. In order to quickly tear off the protective films during the loading process for quick loading and assembly, a film tearing mechanism needs to be set up. However, the existing film tearing mechanism is generally large in size and has a complicated work process. This film tearing mechanism is not suitable for the whole assembly mechanism of a mobile phone and is likely to cause a waste of space. Utility Model Content

[0004] The main purpose of the utility model is to provide a fast film tearing mechanism, aiming to make the film tearing mechanism simple in structure and high in film tearing precision.

[0005] To achieve the above-mentioned purpose, the utility model proposes a rapid film tearing mechanism, comprising a mounting frame for mounting the film tearing mechanism, a steering motor being mounted on one side of the top of the mounting frame, an adjusting plate being sleeved on the rotating shaft of the steering motor, the adjusting plate being provided with a mounting portion away from the rotating shaft of the steering motor, and the mounting portion being provided with a film tearing clamp facing away from the mounting frame;

[0006] When the film tearing mechanism is in a standby state, a line between the mounting portion and the rotating shaft of the steering motor is parallel to a horizontal plane.

[0007] In one embodiment of the present application, the mounting portion is provided with an extension portion and a driving portion toward the film tearing clamp, the extension portion is connected to the mounting portion and gradually extends in a direction away from the mounting frame, and the driving portion is provided at one end of the extension portion away from the mounting frame and is driven and connected to the film tearing clamp.

[0008] In one embodiment of the present application, the driving portion is provided with a limiting groove along a perpendicular direction of the horizontal plane, and two driving blocks are relatively arranged in the limiting groove. The driving blocks are slidably connected to the limiting groove, and one of the driving blocks is connected to one side of the film tearing clamp.

[0009] In one embodiment of the present application, the film tearing jaw is bent at one end away from the steering motor to form a film tearing portion, and the film tearing portion is provided with a chuck at one end away from the film tearing jaw. The chuck is coaxially arranged with the rotating shaft of the steering motor.

[0010] In one embodiment of the present application, the film tearing portion is provided with a relief portion toward the chuck, and the height of the relief portion gradually decreases in a direction approaching the chuck.

[0011] In one embodiment of the present application, the mounting frame is provided with a recovery groove toward the film tearing clamp, and the recovery groove is located below the film tearing clamp. A clearance groove is protruding from one side of the recovery groove relative to the film tearing clamp and the mounting portion, and the clearance groove is connected to the recovery groove, and a material guide portion is provided between the clearance groove and the inner wall of the top end of the recovery groove.

[0012] By adopting the above technical solution, the utility model has the following advantages:

[0013] 1. The mounting frame can make the entire film tearing mechanism more stable and facilitate the installation of the mechanism. Arranging a steering motor on it can also make the steering motor work more stable, thereby improving the film tearing accuracy.

[0014] 2. An adjusting piece is connected to the steering motor. The adjusting piece itself can be rectangular, eccentric, or circular. The mounting portion is located at the end of the adjusting piece away from the motor shaft. In this way, after a film tearing claw is installed on the mounting portion, when the film tearing claw grabs the film set on the component, the steering motor rotates, and the film tearing claw will tear off the film at a uniform speed along an arc trajectory. The film tearing at this angle is relatively stable and rapid, which can avoid tearing the film and effectively improve the film removal effect.

[0015] 3. The entire mechanism only needs the steering motor to rotate and the film tearing claws to clamp to complete the film tearing. The whole machine has a simple structure and a small size. It can be easily coordinated with other mechanisms through the mounting bracket, which is conducive to improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] Reference Figures 1 to 3 In order to achieve the above-mentioned purpose, the utility model proposes a quick film tearing mechanism, including a mounting frame 1 for installing the film tearing mechanism, a steering motor 11 is installed on one side of the top of the mounting frame 1, an adjusting piece 12 is sleeved on the rotating shaft of the steering motor 11, and the adjusting piece 12 is provided with a mounting portion 13 away from the rotating shaft of the steering motor 11, and the mounting portion 13 is provided with a film tearing claw 4 away from the mounting frame 1; when the film tearing mechanism is in the standby state, the connecting line between the mounting portion 13 and the rotating shaft of the steering motor 11 is parallel to the horizontal plane.

[0025] The mounting frame 1 can make the entire film tearing mechanism more stable and facilitate the installation of the mechanism. Arranging the steering motor 11 thereon can also make the operation of the steering motor 11 more stable, thereby improving the film tearing accuracy.

[0026] An adjusting piece 12 is connected to the steering motor 11. The adjusting piece 12 itself can be rectangular, eccentric, or circular. The mounting portion 13 is provided at the end of the adjusting piece 12 away from the motor shaft. In this way, after the film tearing claw 4 is installed on the mounting portion 13, when the film tearing claw 4 grabs the film set on the component, the steering motor 11 rotates, and the film tearing claw 4 will tear off the film at a uniform speed along the arc trajectory. The film tearing at this angle is relatively stable and rapid, which can avoid tearing the film and can effectively improve the film removal effect.

[0027] The entire mechanism only needs the steering motor 11 to rotate and the film tearing claw 4 to clamp to complete the film tearing. The whole machine has a simple structure and a small volume, and can be easily coordinated with other mechanisms through the mounting frame 1, which is conducive to improving the user experience.

[0028] See also Figures 1 to 2In one embodiment of the present application, the mounting portion 13 is provided with an extension portion 14 and a driving portion 2 toward the film tearing clamp 4. The extension portion 14 is connected to the mounting portion 13 and gradually extends in a direction away from the mounting frame 1. The driving portion 2 is provided at one end of the extension portion 14 away from the mounting frame 1 and is driven and connected to the film tearing clamp 4.

[0029] The extension part 14 makes the film tearing jaw 4 longer, which can make the transferred element farther away from the steering motor 11, avoid collision between the mechanism for transferring the element and the main body of the film tearing mechanism, and make the film tearing mechanism and other assembly mechanisms more interconnected. The driving part 2 is used to assist the opening and closing of the film tearing jaw 4 to improve the grip for film tearing.

[0030] See also Figure 1 In one embodiment of the present application, the driving portion 2 is provided with a limiting groove 21 along the perpendicular direction of the horizontal plane, and two driving blocks 22 are relatively arranged in the limiting groove 21. The driving blocks 22 are slidably connected to the limiting groove 21, and one driving block 22 is connected to one side of the film tearing clamp 4.

[0031] The two driving blocks 22 in the limiting groove 21 can move relative to each other, so that the film-tearing jaws 4 can be tightly closed after closing the jaws, effectively improving the gripping force and preventing the jaws from loosening from the film to be torn.

[0032] See also Figures 1 to 3 In one embodiment of the present application, the end of the film tearing jaw 4 away from the steering motor 11 is bent to form a film tearing portion 41, and the end of the film tearing portion 41 away from the film tearing jaw 4 is provided with a chuck 5, and the chuck 5 is coaxially arranged with the rotating shaft of the steering motor 11.

[0033] The tearing portion 41 formed by bending the tearing jaw 4 can make the chuck 5 be on the extension line of the central axis of the motor's rotating shaft. In this way, when the motor rotates, the chuck 5 only changes its direction. Through this structure, after the chuck 5 clamps the diaphragm, it can be flipped by the motor to make the diaphragm be torn apart more stably. In this way, the transfer mechanism that transfers the component with the diaphragm can continue to transfer directly after the motor is completed. The diaphragm can fall off stably, which can effectively improve the tearing efficiency and tearing accuracy, and avoid incomplete tearing of the film and resulting in installation failure.

[0034] See also Figures 1 to 3 In one embodiment of the present application, the film tearing portion 41 is provided with a relief portion 42 toward the chuck 5 , and the height of the relief portion 42 gradually decreases along the direction approaching the chuck 5 .

[0035] The gradual reduction of the yielding portion 42 can make the volume of the chuck 5 smaller, increase the pressure, and make the clamping force greater. At the same time, it can avoid the transfer mechanism from colliding with the film-tearing clamp 4 when delivering the component to be torn off, thereby improving the film-tearing efficiency and protecting the mechanism at the same time. This structure can effectively improve the linkage ability of the film-tearing mechanism and other mechanisms, and can effectively optimize the spatial layout.

[0036] See also Figures 1 to 2 In one embodiment of the present application, the mounting frame 1 is provided with a recovery groove 3 facing the film tearing clamp 4, and the recovery groove 3 is located below the film tearing clamp 4. A clearance groove 31 is protruding from one side of the recovery groove 3 relative to the film tearing clamp 4 and the mounting portion 13. The clearance groove 31 is connected to the recovery groove 3, and a material guide portion is provided between the clearance groove 31 and the inner wall of the top end of the recovery groove 3.

[0037] The recovery groove 3 is directly below the film tearing jaw 4, and can recover the film in the first time, making the machine body easier to clean. The yield groove 31 is set relative to the film tearing jaw 4 and the extension part 14, which can avoid the relevant structure from colliding with the recovery groove 3 when the steering motor 11 rotates, and recover the film in the first time. The material guide part is a slope structure, which can ensure the film recovery efficiency and improve the overall film tearing rate.
