DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0021] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] In a first aspect of the present application, a self-rotating clutch mechanism is provided, such as Figure 1As shown, it includes: a first support frame; a rotating shaft 1, the rotating shaft 1 is rotatably matched with the first support frame, one end of the rotating shaft 1 is connected to the first gear 2, and the rotating shaft 1 is used to drive the stator clamp to rotate; a clutch plate 3, the clutch plate 3 is slidably matched with the first support frame up and down, and the clutch plate 3 is provided with an upper baffle 301 for limiting the stroke of the first support frame; a first motor 4, the first motor 4 is fixedly mounted on the clutch plate 3, and the first motor 4 is connected to the second gear 5; the self-rotation clutch mechanism is configured such that when the first support frame is lifted, the clutch plate 3 slides downward relative to the first support frame to the stroke limit position, at which time the first gear 2 and the second gear 5 are meshed with each other, and the first motor 4 drives the rotating shaft 1 to rotate.
[0024] The stator clamp is used to clamp the motor stator. When the stator is dripping paint, the self-rotating clutch mechanism is placed on the paint dripping station as a whole. At this time, the first gear 2 and the second gear 5 are separated from each other, and the rotating shaft 1 is driven by the motor of the paint dripping station; when the motor stator needs to be moved to other stations, the first support frame is lifted, and the clutch plate 3 slides downward relative to the first support frame under the action of gravity until the upper baffle 301 is against the first support frame. At this time, the first gear 2 and the second gear 5 are meshed with each other, and the first motor 4 drives the rotating shaft 1 to rotate.
[0025] Through the above design, the motor stator can keep rotating during the transfer process, so that the glue and paint in the motor stator can flow as the motor stator rotates due to its viscosity, and will not gather at the bottom of the motor stator, thus preventing the glue and paint from dripping during the transfer of the motor stator, and effectively solving the paint dripping problem that may be encountered during the transfer of the motor stator.
[0026] In some embodiments, Figure 1 As shown, the first support frame includes a cross beam 6, and two suspension rods 7 are connected to the lower side of the cross beam 6. The lower end of each suspension rod 7 is connected to an insertion block 8. The rotating shaft 1 passes through the two insertion blocks 8 in sequence and rotates with the insertion blocks 8.
[0027] Among them, the crossbeam 6 is the main part of the first support frame, which provides support force on the one hand and is easy to carry by hand on the other hand; the plug block 8 is used to form a rotation support for the rotating shaft 1 on the one hand, and is easy to plug and connect with the bracket of the paint dripping station on the other hand.
[0028] In some embodiments, Figure 1 As shown, the first support frame is provided with a slider 9, and the clutch plate 3 is connected to a slide rail 10 that is slidably matched with the slider 9, the slide rail 10 is extended up and down, and the upper baffle 301 is arranged above the slide rail 10. The sliding match design of the slider 9 and the slide rail 10 enables the clutch plate 3 to move smoothly along a preset track, ensuring that the meshing and separation process of the first gear 2 and the second gear 5 is accurate.
[0029] In some embodiments, Figure 1As shown, the clutch plate 3 is arranged on one side of the first support frame close to the first gear 2, and a counterweight 11 is arranged on the other side of the first support frame away from the clutch plate 3. By arranging the counterweight 11 on the other side of the first support frame, the weight of the clutch plate 3 and the first gear 2 can be effectively balanced, thereby reducing the instability factor caused by the center of gravity shift during the transfer process.
[0030] In a second aspect of the present application, a motor stator paint dripping device is provided, such as Figure 2 and Figure 3 As shown, it includes the above-mentioned self-rotation clutch mechanism; it also includes a second support frame and a second motor 12, the second support frame 17 is detachably connected to the first support frame, the second motor 12 is fixedly installed on the second support frame 17, and the second motor 12 is connected to the third gear 13; the second support frame 17 is configured to, when combined with the first support frame, make the clutch plate 3 slide upward relative to the first support frame to the travel limit position, at this time the first gear 2 and the second gear 5 are separated from each other, and the second gear 5 and the third gear 13 are meshed with each other.
[0031] Through the detachable connection between the first support frame and the second support frame 17, and the configuration of the first and second motors and related gears, automatic positioning and rotation control of the motor stator during the paint dripping process are realized. When the work station needs to be transferred, it is only necessary to disassemble the first support frame and the second support frame 17, and then place the first support frame on the corresponding work station bracket, which has high flexibility.
[0032] In some embodiments, the first support frame is provided with two plug-in blocks 8, and the rotating shaft 1 passes through the two plug-in blocks 8 in sequence and rotates with the plug-in blocks 8; the first limiting groove 14 and the second limiting groove 15 are respectively provided on both sides of the second support frame 17, and the height of the first limiting groove 14 is higher than that of the second limiting groove 15. The first limiting groove 14 is used to plug and cooperate with the first plug-in block 8, and the second limiting groove 15 is used to plug and cooperate with the second plug-in block 8.
[0033] Through the height design of the first limit groove 14 and the second limit groove 15, when the two plug blocks 8 of the first support are respectively inserted into the first limit groove 14 and the second limit groove 15, the rotating shaft 1 is in a tilted state, so that during the paint dripping process of the motor stator, it is convenient for the glue and paint to flow from top to bottom under gravity, thereby ensuring the integrity of the glue and paint coverage.
[0034] In some embodiments, the second motor 12 is fixedly mounted on the second support frame 17 via a mounting base 16; the mounting base 16 is configured such that, when the second support frame 17 is close to the first support frame, the mounting base 16 abuts against the lower side of the clutch plate 3 and pushes the clutch plate 3 to move upward relative to the first support frame, so that the first gear 2 and the second gear 5 are separated from each other, and the second gear 5 and the third gear 13 are meshed with each other.
[0035] The clutch plate 3 is supported and positioned by setting the mounting seat 16, and the first limiting groove 14 and the second limiting groove 15 support and position the first support frame, so that when the first support frame is placed on the second support frame, the clutch plate 3 and the first support frame are automatically at different heights, making the operation simpler and more convenient.
[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
