Currently, in order to improve the fit between the permanent magnets and the rotor core, prevent the permanent magnets from flying out due to centrifugal force during high-speed rotation, and increase the reliability of the motor operation, high-temperature resistant glue is filled between the permanent magnets and the rotor core.

[0003] The dispensing of motor rotors is usually done manually. The manual dispensing speed is slow and cannot meet the needs of mass production, resulting in low production efficiency. Manual operation is affected by the coordination of human hands and limb flexibility, resulting in differences in the dispensing angles at different positions on the same rotor. The dispensing quality of the same batch of products is uneven, and it is difficult to ensure the quality and consistency of the dispensing of each motor rotor. Quality problems such as uneven glue coating or glue leakage are prone to occur. There may be a waste of glue during the manual dispensing process because it is difficult to accurately control the amount of glue and the coating method. In view of the above problems, an automatic dispensing equipment for motor rotors is proposed to solve them. Utility Model Content

[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0027] Embodiment 1

[0028] Reference Figure 1 and Figure 2 As shown, an automatic gluing device for motor rotors comprises a stand 1, a rotating component 2 is fixedly installed on the left side of the upper surface of the stand 1, a gluing mechanism 3 is fixedly installed on the right side of the upper surface of the stand 1, a gluing component 4 is fixedly installed on the rear side of the middle of the upper surface of the stand 1, a waste glue collecting tank 5 is arranged between the upper surface of the stand 1 and the rotating component 2 and the gluing mechanism 3, a positioning block 7 is fixedly connected at the top corner position of the upper surface of the stand 1 and the rear side of the waste glue collecting tank 5, the rotating component 2 is used to drive the workpiece 8 to rotate, so that it moves relative to the gluing nozzle 307, which replaces the traditional manual gluing process of the rotor, reduces the time and labor intensity of workers' repetitive labor, and improves the working conditions and safety of the production line.

[0029] Embodiment 2

[0030] Reference Figure 3 As shown, the rotating component 2 includes a motor bracket 201 fixedly connected to the upper side of the platform 1, a rotating motor 202 is fixedly installed on the left side of the motor bracket 201, the output end of the rotating motor 202 passes through the motor bracket 201 and is fixedly connected to a rotating workpiece chuck 203, a plug-in column 204 is fixedly connected to the center of the right side surface of the workpiece chuck 203, a workpiece 8 is plugged into the plug-in column 204, the workpiece 8 and the plug-in column 204 are restricted by a positioning pin, so that the workpiece 8 can be quickly and accurately plugged into the plug-in column 204, thereby improving the speed of loading and unloading.

[0031] In this solution, the working principle of the rotating assembly 2 is as follows: the output end of the rotating motor 202 drives the workpiece clamping plate 203 to rotate, so that the plug 204 rotates, thereby driving the workpiece 8 to perform a circular motion.

[0032] Embodiment 3

[0033] Reference Figure 4 As shown, the dispensing mechanism 3 includes a fixed plate 301 , the upper end of which is fixedly connected to two telescopic rods 302 , the tops of the two telescopic rods 302 are fixedly connected to a cylinder bearing plate 303 , and the top of the cylinder bearing plate 303 is fixedly connected to a cylinder 304 .

[0034] Reference Figure 4 As shown, a connecting piece 305 connected to a mounting plate 306 is fixedly mounted on the output end of the cylinder 304. The mounting plate 306 is fixedly connected to the left side of the connecting piece 305. Four sets of glue dispensing nozzles 307 are fixedly mounted on the mounting plate 306. The glue dispensing nozzles 307 are detachably fixedly mounted and can be replaced to achieve different glue dispensing shapes, glue amounts and glue types to meet the requirements of different products.

[0035] In this solution, the working principle of the dispensing mechanism 3 is as follows: first, the height of the dispensing nozzle 307 is adjusted by adjusting the length of the telescopic rod 302, and then the cylinder 304 pushes the dispensing nozzle 307 to move above the workpiece 8, so that the dispensing nozzle 307 glue outlet is located on the surface of the workpiece 8.

[0036] Embodiment 4

[0037] Reference Figure 5As shown, the glue dispensing component 4 includes a mounting bracket 401, the rear side of which is fixedly connected to a glue cylinder fixing frame 403 by rivets, and four quantitative glue dispensing cylinders 402 are plugged into the mounting bracket 401. The bottom of the quantitative glue dispensing cylinder 402 is connected to the inside of four groups of glue dispensing nozzles 307 through glue injection tubes 308. The specific connection diagram of the quantitative glue dispensing cylinder 402, the glue injection tube 308 and the glue dispensing nozzle 307 is not drawn in the figure. It can be understood that the glue inside the quantitative glue dispensing cylinder 402 flows into the inside of the glue dispensing nozzle 307 through the glue injection tube 308, and realizes the glue dispensing of the motor rotor.

[0038] Embodiment 5

[0039] Reference Figure 1 As shown, there are two positioning blocks 7, and the two positioning blocks 7 are fixedly connected on the same straight line. The positioning blocks 7 limit the position of the waste glue collecting tank 5 so that it is located directly below the workpiece 8. In this way, the glue dripping from the surface of the workpiece 8 during the dispensing process can be completely caught, which helps to maintain a clean and tidy working environment.

[0040] Reference Figure 2 As shown, support pads 6 are fixedly installed at the four corners of the bottom of the stand 1. The material of the support pads 6 is rubber. The support pads 6 can reduce the vibration generated by the rotation of the output end of the rotating motor 202 and the vibration generated by the cylinder 304 when pushing the mounting plate 306 to move. At the same time, the rubber material can also prevent the stand 1 from slipping.

[0041] Working principle: When in use, the worker first puts the workpiece 8 on the plug-in column 204, adjusts the length of the telescopic rod 302 so that the glue nozzle 307 is at a suitable height, and the output end of the cylinder 304 pushes the mounting plate 306 to the top of the workpiece 8. The output end of the rotating motor 202 drives the workpiece clamping plate 203 to rotate, so that the workpiece 8 makes a circular motion. At this time, the four glue nozzles 307 input a fixed amount of glue to the surface of the workpiece 8 under the control of the quantitative glue cylinder 402, so that the glue is evenly distributed on the workpiece 8.
