Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly devices, in particular to an automatic gluing system for a rotor housing. Background Art

[0002] The motor consists of two parts, the rotor and the stator, which realize energy conversion through their interaction. According to the different rotation modes, the motor rotor can be divided into the inner rotor rotation mode and the outer rotor rotation mode. In the inner rotor rotation mode, the core in the middle of the motor is the rotating body, which outputs torque (motor) or receives energy (generator). The outer rotor rotation mode uses the outer body of the motor as the rotating body, which is convenient for application in various occasions.

[0003] The motor rotor is an important part of the motor. Its working principle is based on the law of electromagnetic induction and the principle of magnetic field interaction. When the stator winding is energized, a rotating magnetic field is generated. This magnetic field interacts with the conductor (or permanent magnet) in the rotor to generate electromagnetic force, causing the rotor to start rotating. In an electric motor, the rotor outputs mechanical energy through rotation; in a generator, the rotor converts mechanical energy into electrical energy through rotation.

[0004] The common motor rotor consists of a rotor housing and rotor magnetic sheets arranged on the inner wall of the rotor housing. In the prior art, most of the magnetic sheets are manually attached, that is, adhesive is applied to the inner wall of the rotor housing in advance, and then the material is manually taken to attach a number of rotor magnetic sheets to the inner wall of the rotor housing.

[0005] Since the gluing of the rotor shell is done manually, it is difficult to ensure the uniformity of the gluing, which is not only inefficient but also easy to cause the rotor magnets to debond and fall off due to external vibration after magnet affixation, thus affecting the qualified rate of the product.

[0006] Therefore, a new technical solution is urgently needed to solve this technical problem. Utility Model Content

[0007] The purpose of the utility model is to overcome the above-mentioned problems of the prior art and to provide an automatic gluing system for a rotor shell, so as to solve the technical problem that in the prior art, the inner wall of the rotor shell is manually coated with glue, which not only has low coating accuracy and low efficiency, but also easily causes the rotor magnetic sheets to debond and fall off due to external vibration after magnetization, thereby affecting the technical problem of the qualified rate of the product.

[0008] The above objectives are achieved through the following technical solutions:

[0019] The utility model provides an automatic gluing system for rotor shells. According to the requirements of the magnetizing process, a number of rotor shell trays for placing rotor shells are arranged, and the trays are arranged in a circle with the center of the turntable as the center of the circle. The rotor shell trays are driven to rotate by the turntable, and are regularly paused when reaching the gluing mechanism area to facilitate the gluing operation. After the gluing is completed, the rotor shell trays continue to rotate to bring the glued rotor shell trays to the next station to complete the magnetizing. This system is not only simple in structure and occupies a small space, but also can realize the rotation drive of different stations such as feeding, gluing, and magnetizing the rotor shell. Compared with traditional manual gluing, it has a high degree of automation and can ensure that the gluing of each rotor shell is the same, which can effectively improve the qualified rate of gluing and work efficiency.

[0031] The utility model is further described in detail below based on the accompanying drawings and embodiments. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0032] like Figures 1 to 3 As shown, an automatic gluing system for a rotor shell includes a rotor shell turntable mechanism 1 and a gluing mechanism 3 arranged on a work surface 4;

[0033] The rotor shell turntable mechanism 1 comprises a turntable rotation drive assembly 101 connected to the work surface 4, a turntable 102 is arranged on the turntable rotation drive assembly 101, and the turntable 102 can be horizontally rotated under the drive of the turntable rotation drive assembly 101, and at least one tray rotation assembly 103 is arranged on the surface of the turntable 102, and a rotor shell tray 104 is arranged on the tray rotation assembly 103, and the rotor shell tray 104 is used to place the rotor shell 2;

[0034] The gluing mechanism 3 includes a tray rotation driving assembly 301 for driving the rotor shell tray 104 to rotate, and a glue gun assembly 302 for gluing the rotor shell 2 .

[0035] Working principle:

[0036] Driven by the turntable rotation drive assembly 101, the turntable 102 rotates horizontally to transmit any designated rotor shell tray 104 to the tray rotation drive assembly 301 of the glue application mechanism 3. The tray rotation drive assembly 301 drives the rotor shell tray 104 carrying the rotor housing 2 to rotate horizontally.

[0037] At the same time, the glue gun assembly 302 corresponds to the inner wall of the rotor shell tray 104 and continuously or intermittently glues the inner wall of the rotor housing 2 .

[0038] like Figure 4 As shown, the turntable rotation drive assembly 101 in this embodiment includes a hub bearing 105 connected to the work surface 4 and a turntable drive motor 106, a gear 107 is sleeved on the outer ring of the hub bearing 105, and the top of the gear 107 is connected to the turntable 102;

[0039] The rotating shaft of the turntable driving motor 106 is connected to a gear shaft 108 that can mesh with the gear 107 .

[0040] Under the drive of the turntable driving motor 106 , the gear shaft 108 drives the gear 108 to rotate, and indirectly drives the turntable 102 to rotate horizontally, and the rotation direction can be counterclockwise or clockwise.

[0041] Through this mechanism, any rotor shell tray 104 can be transmitted to the tray rotation drive assembly 301 of the gluing mechanism 3 .

[0042] As an optimization of this solution, the centers of the rotating disk 102, the gear 107, and the hub bearing 105 are coaxial. In this way, the three can be ensured to rotate stably on the same rotation axis, and the rotor shell tray 104 can be better transmitted to the tray rotation drive assembly 301 of the glue spraying mechanism 3.

[0043] As a specific embodiment of the present scheme, there are at least three rotor shell trays 104, which are arranged in a circle around the center of the turntable 102. Driven by the rotation of the turntable 102, each rotor shell tray 104 rotates along the same circular trajectory, and can be better driven to the position of the tray rotation drive assembly 301 to perform individual rotor shell tray 104 rotation drive control.

[0044] This mechanism can realize the continuous and uninterrupted gluing operation on the rotor shell 2 carried on the rotor shell tray 104, and the rotor shell tray 104 after gluing will rotate the finished product to the next position for unloading under the drive of the turntable 102, and continue to complete the loading at the next position, finally realizing the cyclic loading, gluing, magnetizing, unloading and other operations.

[0045] In this embodiment, the outer side surface of each rotor shell tray 104 extends out of the turntable 102 so as to be better driven to rotate by the tray rotation driving assembly 301 .

[0046] like Figure 5As shown, the tray rotating assembly 103 includes a tray rotating shaft sleeve seat 109 vertically connected to the turntable 102, and a tray rotating shaft 110 sleeved by the tray rotating shaft sleeve seat 109, and a ball bearing 111 is arranged between the outer wall of the tray rotating shaft 110 and the inner wall of the tray rotating shaft sleeve seat 109, and the tray rotating shaft 110 can freely rotate relative to the tray rotating shaft sleeve seat 109;

[0047] The top of the tray shaft 110 is connected to the rotor housing tray 104 .

[0048] This structure ensures that the rotor housing tray 104 can rotate freely relative to the turntable 102 under the action of external force.

[0049] like Figure 6 As shown, the gluing mechanism 3 further includes a gluing bracket 303 fixedly connected to the work surface 4 , and the glue gun assembly 302 and the tray rotation drive assembly 301 are arranged on the gluing bracket 303 from top to bottom.

[0050] Among them, the glue gun assembly 302 includes a pair of longitudinal slide rails 304 arranged on the gluing bracket 303, the longitudinal slide rails 304 are connected with a lifting plate 305, and the lifting plate 305 is connected with a glue gun 306; the lifting plate 305 is driven by a glue gun lifting screw 307 to perform vertical lifting, so as to achieve the purpose of adjusting the height of the glue gun 306 so that it can correspond to the rotor shell tray 104 of different specifications.

[0051] It should be noted that the glue gun 306 in this embodiment can be a single glue gun or a double glue gun, wherein the single glue gun is used to apply a single glue, while the double glue gun can be used to apply mixed glue.

[0052] The glue gun 306 can be adjusted in angle relative to the lifting plate 305. As a specific embodiment of the angle adjustment, the glue gun 306 is connected via a glue gun slide 308, and the glue gun slide 308 is slidably connected to the glue gun moving seat 309 via a glue gun slide rail 310; an arc groove (not marked in the figure) is provided on the lifting plate 305, and the glue gun moving seat 309 is angle-locked with the arc groove via a locking screw.

[0053] In this embodiment, the inclination angle of the glue gun 306 is adjusted by the cooperation of the arc groove and the locking screw, and the forward movement of the glue gun is adjusted by the glue gun slide rail 310, so that the glue gun 306 can adapt to rotor housings of different specifications and different gluing requirements.

[0054] In this embodiment, the tray rotation drive assembly 301 includes a support plate 311 fixedly connected to the glue-applying bracket 303, and a swing plate 312 hinged to the support plate 311, and a tray rotation motor 313 is provided on the swing plate 312. A knurled wheel 314 capable of acting on the outer wall of the rotor shell tray 104 is connected to the rotating shaft of the tray rotation motor 313.

[0055] In order to enable the knurled wheel 314 to act closely on the rotor shell tray 104 shifted to this area, the support plate 311 and the swing plate 312 are connected by a tension spring 315 in this embodiment, so that the swing plate 312 can indirectly drive the knurled wheel 314 to be tightly attached to the outer wall of the rotor shell tray 104, thereby achieving better rotational drive.

[0056] The above description is only for illustrating the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
