[0048] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific implementation disclosed below.

[0049] The specific embodiments of the present application will be described in detail below with reference to the drawings. Figures 1-11The adsorption rotary film tearing mechanism 1 and the automatic film tearing device 100 for the motor rotor assembly line are further described.

[0050] Please refer to Figures 1-6 The utility model discloses a kind of adsorption rotary film tearing mechanism 1, comprising: film tearing support vertical frame 11, film removing roller 12, adsorption rotary film tearing roller 13, first rotary drive 14 and second rotary drive 15;Film tearing support vertical frame 11 is overall frame structure, film removing roller 12 and adsorption rotary film tearing roller 13 are arranged at intervals, and film removing roller 12 and adsorption rotary film tearing roller 13 are respectively rotatably installed on film tearing support vertical frame 11;First rotary drive 14 is installed on one side of film tearing support vertical frame 11, and first rotary drive 14 is connected with one end of film removing roller 12 and is used to drive film removing roller 12 to rotate;Second rotary drive 15 is installed on one side of film tearing support vertical frame 11, and second rotary drive 15 is connected with one end of adsorption rotary film tearing roller 13 and is used to drive adsorption rotary film tearing roller 13 to rotate;Adsorption rotary film tearing roller 13 has adsorption plane 1321 of planar structure on the outside, the inside of adsorption rotary film tearing roller 13 is provided with adsorption air channel formed therein, vacuum adsorption hole that is communicated with adsorption air channel is arranged on adsorption plane 1321, and one end of adsorption rotary film tearing roller 13 is provided with rotary joint 16 that is communicated with adsorption air channel.

[0051] The adsorption rotary film tearing mechanism 1 of the embodiment is used in cooperation with film suction manipulator 3. Film suction manipulator 3 can include a three-axis module and a vacuum chuck 311 loaded on the three-axis module. The three-axis module is used to move the vacuum chuck 311 in X, Y and Z axes. The three-axis module can be a commercially available component or a combination of three one-way movement modules. The vacuum chuck 311 is used to provide a vacuum suction force to suck the protective film 00.

[0052] Film tearing support vertical frame 11 is used to provide a mounting base for film removing roller 12, adsorption rotary film tearing roller 13, first rotary drive 14 and second rotary drive 15, etc.

[0053] First rotary drive 14 and second rotary drive 15 are used to provide rotary power.

[0054] When in use, rotary joint 16 is used to connect an external vacuum air source (such as a vacuum pump) and adsorption air channel to provide negative pressure adsorption power for the vacuum adsorption hole.

[0055] The use process of the utility model is introduced as follows. The adsorption rotary film tearing mechanism 1 is used for film tearing operation of the protective film 00, and the protective film 00 comprises the adhesive bottom film 01 and the cover film 02; the film suction manipulator 3 is used for adsorbing the protective film 00 and moving to the film removing roller 12 and the adsorption rotary film tearing roller 13 in sequence; the film removing roller 12 is used for removing the excessive protective film 00 adsorbed by the film suction manipulator 3 by mistake; and the adsorption rotary film tearing roller 13 is used for adsorbing one side of the bottom film 01 and rotating by a preset angle to separate the bottom film 01 and the cover film 02. When the film suction manipulator 3 adsorbs the protective film 00, one side of the protective film (the side with the cover film 02) is adsorbed. Under normal circumstances, the film suction manipulator 3 only adsorbs one protective film 00 each time, but if the adjacent protective films 00 are adhered, there may be a situation that two or more protective films 00 are adsorbed at a time. When the film suction manipulator 3 carrying the adsorbed protective film 00 passes above the film removing roller 12, the film removing roller 12 rotates and removes the excessive protective film 00 adsorbed by the film suction manipulator 3 by mistake. Since there is only one protective film 00 directly adsorbed by the film suction manipulator 3, the protective film 00 is still retained on the film suction manipulator 3. The angle of the adsorption rotary film tearing roller 13 is preset to ensure that the adsorption plane 1321 faces upward, the film suction manipulator 3 adsorbs the protective film 00 and moves to above the adsorption rotary film tearing roller 13, the side of the bottom film 01 far from the film removing roller 12 is attached to the adsorption plane 1321, and the side of the bottom film 01 is adsorbed and fixed by the adsorption rotary film tearing roller 13. Under the action of the first rotary drive 14, the adsorption rotary film tearing roller 13 rotates by a preset angle, the bottom film 01 is torn off, and the cover film 02 is still adsorbed on the film suction manipulator 3.

[0056] It should be noted that the cover film 02 torn by the adsorption rotary film tearing mechanism 1 of the utility model can be attached to the motor product, and can be used for other products that need to be covered with a film.

[0057] The adsorption rotary film tearing mechanism 1 of the utility model has a simple and reliable structure, and when used, the adsorption rotary film tearing roller 13 adsorbs one side of the bottom film 01 and rotates, so that the cover film 02 and the bottom film 01 can be completely separated, without a separate film tearing pretreatment process, and the process is simplified. Compared with the structure that clamps and tears off the bottom film 01 by using a clamp jaw, the structure of the utility model does not need the bottom film 01 to exceed the edge of the cover film. Whether the edge of the bottom film 01 exceeds the edge of the cover film or not, the bottom film 01 can be easily torn, and the utility range is wide. Moreover, the utility model removes the excessive protective film 00 adsorbed by the film suction manipulator 3 by mistake through the added film removing roller 12, can solve the problem that multiple protective films 00 are adhered and cause multiple protective films 00 to be adsorbed by mistake at a time when the protective film 00 is actually adsorbed, and can quickly and accurately complete the film tearing operation of a single protective film 00. By using the structure of the utility model, no film tearing pretreatment process is needed, and whether the edge of the bottom film 01 exceeds the edge of the cover film 02 or not, the bottom film 01 can be easily torn, and the utility range is wide.

[0058] According to a specific embodiment of the present invention, the adsorption rotary film-tearing mechanism 1 further includes: a material feeding guide cylinder 17 and a film-tearing waist mounting plate 18. The material feeding guide cylinder 17 is fixed to the lower part of the film-tearing support vertical frame 11. The material feeding guide cylinder 17 and the film-tearing support vertical frame 11 together form a bottom film receiving and discharging channel 19. The two opposite sides of the film-tearing support vertical frame 11 are the power side 112 and the observation side, respectively. The observation side is provided with an observation port 111 that communicates with the bottom film receiving and discharging channel 19. The first rotary drive 14 and the second rotary drive 15 are both located on the power side 112. There are two film-tearing waist mounting plates 18, and the two film-tearing waist mounting plates 18 are respectively fixed to the outer middle section of the film-tearing support vertical frame 11.

[0059] In this embodiment, during use, the film-tearing waist mounting plate 18 is fixed to the mounting base plate 2, and the material discharge guide cylinder 17 is located below the mounting base plate 2, which facilitates the smooth discharge of materials (the bottom film 01 torn off by the adsorption rotating film-tearing roller 13 and the excess protective film 00 rolled off by the film removal roller 12).

[0060] The film-tearing support frame 11 serves both as a support and a storage unit. Specifically, the bottom film receiving and discharging channel 19 is mainly used to receive the bottom film 01 torn off by the adsorption rotating film-tearing roller 13, and also to receive the protective film 00 that rolls off the film removal roller 12. The observation port 111 facilitates observation of the material suction. The power side 112 is used to centrally install the rotating power components, and the observation side is positioned opposite to the power side 112. This design helps improve the safety of the adsorption rotating film-tearing mechanism 1.

[0061] According to a specific embodiment of the present invention, the adsorption rotary film-tearing mechanism 1 further includes a blowing unit, which includes a connector mounting frame 20 and an air blowing connector 21 mounted on the connector mounting frame 20. One end of the air blowing connector 21 has an air outlet 211. The connector mounting frame 20 is mounted on the top of the power side 112, and the air blowing connector 21 is located between the film removal roller 12 and the adsorption rotary film-tearing roller 13, and the air outlet 211 faces the bottom film receiving discharge channel 19.

[0062] In this embodiment, the air blowing connector 21 is used to introduce pressurized gas, which is used to blow the material (the bottom film 01 torn off by the adsorption rotary film tearing roller 13 and the excess protective film 00 rolled off by the film removal roller 12) to the bottom of the bottom film receiving and discharging channel 19 in a timely manner. This effectively avoids the material from sticking to the adsorption rotary film tearing roller 13 or the film removal roller 12, and also allows the bottom film receiving and discharging channel 19 to hold more material, which is conducive to the smooth and continuous film tearing operation.

[0063] According to a specific embodiment of the present invention, the film removal roller 12 is cylindrical, and bristles (not shown) are distributed on the outer side of the film removal roller 12.

[0064] In this embodiment, the brush bristles (not shown) rotate with the film removal roller 12, which can easily and reliably sweep away the excess protective film 00 picked up by the suction robot.

[0065] According to a specific embodiment of the present invention, there are multiple air blowing joints 21, and the multiple air blowing joints 21 are arranged sequentially at intervals along the direction from the adsorption rotating film tearing roller 13 to the film removal roller 12.

[0066] In this embodiment, the structure facilitates the formation of a pressure air curtain, resulting in a better effect of blowing away materials.

[0067] According to a specific embodiment of this utility model, the adsorption rotary tearing roller 13 includes, in sequence, a first connecting shaft 131, a tearing roller body 132, and a second connecting shaft 133; the first connecting shaft 131 is cylindrical in shape, the second connecting shaft 133 is cylindrical in shape, the tearing roller body 132 is rectangular in shape, and the top surface of the tearing roller body 132 is an adsorption plane 1321; the adsorption air passage includes a first air passage 1311 formed in the first connecting shaft 131 and a second air passage 1322 formed in the tearing roller body 132, the first air passage 1311 penetrates the first connecting shaft 131, one end of the second air passage 1322 is connected to one end of the first air passage 1311, and the second air passage 1322... The other end extends into the body 132 of the film-tearing roller; the rotary joint 16 is installed on the side of the first connecting shaft 131 away from the body 132 of the film-tearing roller, and the rotary joint 16 is connected to the other end of the first air passage 1311; the vacuum adsorption hole includes a rectangular adsorption groove 1323 and a plurality of adsorption holes 1324 arranged in a row, the first connecting shaft 131 and the second connecting shaft 133 are coaxial, the adsorption groove 1323 is located directly above the axis of the first connecting shaft 131, and the adsorption holes 1324 are located on the side of the adsorption groove 1323 away from the film-removing roller 12; the second rotary drive 15 is a toothed belt drive structure 152 driven by a stepper motor 151; and the second rotary drive 15 is connected to the outer side wall of the first connecting shaft 131.

[0068] In this embodiment, the adsorption rotary film-tearing roller 13 is composed of three sections: a first connecting shaft 131, a film-tearing roller body 132, and a second connecting shaft 133, which facilitates segmented processing and assembly. Both the first connecting shaft 131 and the second connecting shaft 133 are cylindrical, allowing for rotational connection with the film-tearing support frame 11. The film-tearing roller body 132 is generally rectangular, forming a large adsorption plane 1321, ensuring sufficient area for adsorbing the bottom film 01. It also ensures sufficient space for forming the adsorption groove 1323 and adsorption holes 1324.

[0069] For vacuum adsorption holes, if they are set as multiple rectangular adsorption grooves 1323, the adsorption grooves 1323 are long and continuous structures, and the protective film 00 is easily deformed by adsorption. If they are set as small circular adsorption holes 1324, the adsorption force is small and it is difficult to adsorb stably.

[0070] In this embodiment, the adsorption groove 1323 and the adsorption hole 1324 are used in combination to ensure adsorption force while minimizing deformation. Specifically, the adsorption groove 1323 is a long, narrow rectangle, providing a large adsorption force. The adsorption hole 1324 is a round or elliptical hole, preferably a round hole. The adsorption hole 1324 consists of multiple small, spaced-apart round holes arranged in a line to disperse the adsorption positions. When adsorbing the bottom film 01, the distance between the adsorption groove 1323 and the edge of the bottom film 01 is greater than the distance between the adsorption hole 1324 and the edge of the bottom film 01, making the protective film 00 less prone to deformation.

[0071] In this embodiment, the belt drive structure, in conjunction with the rotary joint 16, enables the rotation of the adsorption-rotating film-tearing roller 13 without affecting the connection of the vacuum source. Specifically, the rotary joint 16 is a readily available purchased component. One end of the rotary joint 16 is connected to the end of the first connecting shaft 131 and rotates with the adsorption-rotating film-tearing roller 13. The other end of the rotary joint 16 is used to connect to the vacuum source. The second rotation drive 15 adopts a motor-driven belt drive structure and is connected to the outer wall of the first connecting shaft 131. One end of the first connecting shaft 131 is used to connect to the rotary joint 16, and one outer wall of the first connecting shaft 131 is used to connect to the second rotation drive 15, enabling simultaneous connection of the vacuum source and rotational power.

[0072] According to a specific embodiment of this utility model, the two ends of the tear film roller body 132 are respectively provided with a recessed first docking hole 1325 and a second docking hole 1326. One end of the first connecting shaft 131 is inserted into the first docking hole 1325, and one end of the second connecting shaft 133 is inserted into the second docking hole 1326. The side of the tear film roller body 132 is provided with a first side locking pin hole 1327 communicating with the first docking hole 1325. A lateral locking screw (not shown in the figure) is provided in the first side locking pin hole 1327, and the lateral locking screw abuts and fixes the outer side wall of the first connecting shaft 131. The side of the tear film roller body 132 is provided with a second docking hole 1326 communicating with the second docking hole 1326. A side locking pin hole 1328 is provided, and a side locking screw (not shown in the figure) is provided in the second side locking pin hole 1328. The side locking screw abuts and fixes the outer side wall of the second connecting shaft 133. The first connecting shaft 131 and the second connecting shaft 133 are rotatably connected to the film tearing support frame 11 via bearings 22. A rotation angle positioning sensor 23 is fixedly provided on the side of the second connecting shaft 133 away from the second docking hole 1326. A photoelectric sensor 24 is provided below the rotation angle positioning sensor 23 to cooperate with the rotation angle positioning sensor 23 and to detect the rotation angle of the adsorption rotating film tearing roller 13. The photoelectric sensor 24 is fixed on the side wall of the film tearing support frame 11.

[0073] In this embodiment, the first connecting shaft 131 and the second connecting shaft 133 are respectively inserted into the body 132 of the film-tearing roller and locked with locking screws. This improves the stability of the connection and the compactness of the structure. The rotation angle positioning sensor 23 rotates with the adsorption rotating film-tearing roller 13. When the photoelectric sensor 24 detects the passage of the rotation angle positioning sensor 23, it can obtain the rotation angle information of the adsorption rotating film-tearing roller 13, providing angle information to the electrical control system and providing conditions for the precise control of the rotation angle of the adsorption rotating film-tearing roller 13.

[0074] Please continue to combine Figures 7-11 This utility model also discloses an automatic film-tearing device 100 for a motor rotor assembly line, comprising: a mounting base plate 2 and a suction manipulator 3, a film hopper 4, and an adsorption-rotation film-tearing mechanism 1 as described in the above embodiments, respectively mounted on the mounting base plate 2; the automatic film-tearing device 100 for a motor rotor assembly line is used for the film-tearing operation of a protective film 00, the protective film 00 comprising an adhesive base film 01 and a cover film 02; there is an adhesive 03 between the base film 01 and the cover film 02, the adhesive 03 is firmly bonded to the cover film 02, and when the base film 01 is removed, the adhesive 03 remains on the cover film 02.

[0075] In this embodiment, the mounting base 2 is used to provide a mounting foundation for other modules. The film hopper 4 is used to hold the protective films 00 stacked in sequence. The film suction robot 3 is used to suction the protective films 00 from the film hopper 4 and move them in sequence above the film removal roller 12 and the suction rotating film tearing roller 13. After removing the bottom film 01, the film suction robot 3 is also used to transfer the cover film 02 to the film-to-be-coated station 200. Using the adhesive 03 under the cover film 02, the cover film 02 is covered and bonded to one or more products, completing the film application process.

[0076] When assembling the motor rotor, after the assembly, spot welding and glue filling processes of the spool and rotor are completed, the resulting rotor assembly is located at the film-to-coating station 200. It is then transferred to the film-to-coating station 200 by the film suction robot 3 and covered onto the workpiece that needs to be coated. This reduces the entry of external dust into the spool or the adhesion to the glue filling area, thus providing temporary dust protection. When the conditions for the next process are met, the covering film 02 is removed, and the next process is carried out.

[0077] It should be noted that how to attach the covering film 02 to the rotor assembly is not the utility model point of this utility model. The fact that this utility model does not specifically describe it does not affect the full disclosure of this utility model.

[0078] Compared with the prior art, the automatic film-tearing device for motor rotor assembly line of this utility model applies the adsorption and rotation film-tearing mechanism of the above embodiment. In conjunction with the film suction robot and film hopper, it can quickly and accurately complete the automatic continuous film-tearing operation of a single protective film, providing conditions for the next film-applying process.

[0080] In this embodiment, the film-tearing waist mounting plate 18, the material drop guide cylinder 17, and the film-tearing support vertical frame 11 are integrated into one structure. The material drop guide cylinder 17 is used to guide the falling material to the area below the mounting base plate 2. During use, the protective films 00 are stacked one by one in the protective film stacking cavity 43, and three positioning rods 44 pass through the three positioning holes 04 of each protective film 00 to ensure that all the protective films 00 in the film hopper 4 are aligned vertically, which is beneficial for the positioning and suction of the flexible adsorption component 31. During use, the vacuum suction cup 311 extends into the protective film stacking cavity 43, and the three positioning rods 44 pass through the three clearance holes 3112 to ensure that the vacuum suction cup 311 can move downward smoothly and adsorb the protective film 00. When the protective film 00 on one film hopper 4 is exhausted, the proximity sensor 45 detects the lack of material and sends a replenishment signal to the electrical control system. At this time, the vacuum suction cup 311 picks up the protective film 00 from another film hopper 4 to ensure continuous operation.

[0081] According to a specific embodiment of this utility model, the triaxial module includes: an X-axis linear module 33 mounted on the mounting base plate 2, a Y-axis linear module 34 mounted on the X-axis linear module 33, and a Z-axis linear module 35 mounted on the Y-axis linear module 34.

The vision module 32 is an existing directly purchased component, consisting of a camera, lens, light source, and adjustment structure, used for image positioning. It can accurately acquire the position information of the film hopper 4, the film removal roller 12, the adsorption rotating film tearing roller 13, and the film-to-be-coated station 200, etc., and, combined with the electrical control system, control the movement of the three-axis module to accurately move the flexible adsorption component 31 to the required station, thereby achieving fully automated film tearing operation. In use, the upper part of the vacuum suction tube 313 is connected to a vacuum air source to ultimately provide suction force to the suction hole 3111 to pick up the protective film 00.

[0083] When the three-axis module carrying the protective film 00 moves downwards and comes into contact with any component (such as the film removal roller 12, the adsorption rotating film tearing roller 13, and the stacked protective film 00), the compression spring 316 is compressed, which can avoid direct impact with the component, achieve flexible contact, and improve the safety of use.
