Description

Technical Field

[0001] The invention relates to the technical field of micro-motor production and processing, and particularly discloses a micro-motor rotor glue dispensing device. Background Art

[0002] During the production process of micromotors, glue must be applied to the grooves on the rotor surface and the upper end face where the blades are mounted. Currently, the glue dispensing process for micromotor rotors is mainly divided into two methods: manual dispensing and semi-automatic rotary dispensing. Manual dispensing is not only inefficient but also suffers from uneven dispensing, resulting in inconsistent quality of the manufactured micromotors. Semi-automatic rotary dispensing, on the other hand, utilizes manual loading and then evenly applies glue to all grooves and the upper end face of the rotor during the rotor's rotation.

[0003] For example, the utility model patent with application number 2021204166139 discloses an automatic dispensing device for a motor rotor core, including a dispensing device, a dispensing control device, and a glue box; the dispensing control device is connected to the dispensing device, the dispensing device is connected to the glue box, and the glue box is connected to the dispensing control device; the dispensing device is composed of a dispensing support, a rotating mechanism, and a dispensing mechanism. A rotating mechanism is installed in the middle of the dispensing support, and a dispensing mechanism is installed on the top of the dispensing support. The utility model patent discloses a typical semi-automatic rotary dispensing machine. When the semi-automatic rotary dispensing machine is used to dispense glue on the rotor of a micromotor, although its dispensing efficiency and dispensing uniformity are improved to a certain extent, since only one rotor can be dispensed at a time, manual loading and unloading are required after the dispensing is completed, which limits the dispensing efficiency of the micromotor rotor. In addition, after dispensing glue on a groove of the micromotor rotor, the rotor needs to be rotated quickly by a rotary mechanism to switch the dispensing target position. However, the rotor is rotated before the glue liquid has completely penetrated into the groove on the rotor surface. As a result, the glue liquid is easily thrown out by the centrifugal force, resulting in the glue liquid being unable to be effectively filled into the groove on the rotor surface. In particular, when dispensing glue on the rotor shaft end during the rotation of the rotor, the glue in the groove is easily thrown out, affecting the dispensing effect of the micromotor rotor. Therefore, in response to the above-mentioned shortcomings of the existing semi-automatic rotary dispensing machine for motor rotors, the present application proposes a micromotor rotor dispensing device that can effectively solve the above-mentioned technical problems. Summary of the Invention

[0004] The present invention aims to provide a micromotor rotor dispensing device to solve the problems of limited dispensing efficiency and poor dispensing effect of existing semi-automatic rotary dispensing machines.

[0005] The present invention is achieved through the following technical solutions:

[0006] A micromotor rotor dispensing device comprises a turntable and a turntable seat, wherein the turntable is rotatably disposed in a circular groove of the turntable seat, wherein a plurality of arcuate tooth surfaces are evenly arranged on the inner wall of the circular groove, wherein a plurality of rotor holders are rotatably connected to the turntable in an annular array, wherein the upper end of the rotor holder is provided with a positioning groove, and the lower end is connected to a gear extending from the turntable, wherein the outer end of the gear and the plurality of arcuate tooth surfaces are arranged on the same loop line, and a rotor end face dispensing mechanism and a plurality of evenly distributed groove dispensing mechanisms are arranged on the periphery of the turntable seat;

[0007] The rotor end face dispensing mechanism includes a frame and a rotating motor. The rotating motor is arranged at the upper end of the frame. The lower end of the output shaft of the rotating motor is connected to a second dispensing gun head through an oblique bar. The lower end of the second dispensing gun head is connected to a second glue discharge needle tube inclined downward, and the upper end is connected to a second glue delivery pipe connected to the second glue delivery pump on the glue tank.

[0008] The micromotor rotor dispensing device designed by the present invention dispenses glue on a micromotor rotor by sequentially inserting the micromotor rotor into a positioning slot. The turntable is then driven to rotate a certain angle within the circular groove, rotating the micromotor rotor to the first groove dispensing mechanism. The groove dispensing mechanism then injects glue into the grooves of the micromotor rotor. The turntable is then driven to rotate a certain angle again. During this rotation, the gear at the lower end of the rotor holder passes the first arc-shaped tooth surface. Due to the meshing transmission between the two, the rotor holder rotates a certain angle, shifting the unapplied grooves on the micromotor rotor to the outer end. The remaining groove dispensing mechanisms then dispense glue to these grooves.

[0009] In addition, when the micromotor rotor rotates to the dispensing mechanism on the rotor end face, the rotating motor drives the second dispensing gun head to rotate one circle, so that the dispensing needle rotates around the end face of the rotor shaft, thereby evenly dripping the glue on the end face of the micromotor rotor through the dispensing needle. During the whole process, the micromotor rotor does not need to rotate on its own, thereby avoiding the centrifugal force generated by the high speed of the micromotor rotor itself during the dispensing process, which can effectively ensure the dispensing effect of the micromotor rotor.

[0010] As a specific setting of the above scheme, the groove dispensing mechanism includes a stand and a telescopic device, a slide is provided on the stand, and the telescopic end of the telescopic device is connected to the slide, the outer end of the slide is connected to a first dispensing gun head, the lower end of the first dispensing gun head is connected to a first glue discharge needle tube inclined downward, and the upper end is connected to a first glue delivery pipe connected to the first glue delivery pump on the glue tank; the above-mentioned extension and shortening of the telescopic device causes the glue discharge needle tube to move up and down along the rotor groove, thereby evenly injecting the glue into the groove.

[0011] As a further configuration of the above scheme, it also includes a chassis, and the turntable seat, rotor end face dispensing mechanism and groove dispensing mechanism are all arranged on the upper surface of the chassis; the above-mentioned base is the main structure, which is used to install and place various components.

[0012] As a specific setting of the above scheme, a bearing is provided at the center of the bottom wall of the circular rotating groove, and a vertical shaft is provided in the bearing. The upper end of the vertical shaft is connected to the turntable, and the lower end is connected to the driving motor; the specific driving motor can be a stepper motor, and the rotation angle of the turntable is precisely controlled by controlling the pulse signal of the stepper motor, so that each pause position is aligned with the dispensing mechanism.

[0013] As a specific setting of the above scheme, the number of teeth on the gear is n times the number of teeth on the arc-shaped tooth surface, and n is the number of grooves on the micromotor rotor; taking a micromotor rotor with four grooves as an example, the number of teeth on its gear is set to 4 times the arc-shaped tooth surface, thereby ensuring that every time the turntable rotates a certain angle and passes through the arc-shaped tooth surface position, the micromotor rotor rotates 90° with the rotor holder, thereby switching the grooves on the rotor for dispensing processing.

[0014] As a specific setting of the above scheme, a number of stepped circular holes are opened on the turntable in a ring array, and the rotor holder is a stepped cylindrical shape and is inserted into the stepped circular holes; the above is a specific way of rotating the rotor holder in the turntable, which can realize the disassembly between the rotor holder and the turntable, so as to replace the rotor holder of different signals to adapt to the micromotor rotor of different signals.

[0015] As a further configuration of the above solution, a corrugated expansion section is further provided on the second rubber delivery hose; the corrugated expansion section can make the rotor end face dispensing mechanism extend and shorten during one rotation, thereby preventing the second rubber delivery hose from getting entangled.

[0016] As a further configuration of the above scheme, it also includes an automatic loading mechanism, which includes a conveying track connected to the vibrating loading tray at one end, and a unloading channel located directly above the rotor holder is provided at the other end of the conveying track; the above automatic loading mechanism is connected to the vibrating loading tray through the conveying track, so that the micromotor rotor to be glued can be continuously conveyed to the turntable for glue dispensing, without the need for manual loading.

[0017] As a further arrangement of the above scheme, a material dispensing disc is further provided in the conveying track near one side of the discharge channel, and a number of arc-shaped material dispensing grooves are evenly opened on the circumferential surface of the material dispensing disc, and a material dispensing motor is connected to the lower end of the material dispensing disc; the above scheme controls the material dispensing motor to rotate a certain angle each time, and then uses the arc-shaped material dispensing groove to dispense a micromotor rotor into the discharge channel each time for quantitative and fixed-point dispensing. Beneficial effects

[0018] 1. This micromotor rotor dispensing device realizes the streamlined movement of the micromotor rotor through the rotation process of the turntable, and through the meshing action of the gear and the arc-shaped tooth surface, the micromotor rotor can switch to the adjacent un-dispensed groove every time the turntable rotates a certain angle, and then the groove dispensing mechanism completes the dispensing process of the groove from top to bottom; the entire dispensing device not only realizes the streamlined dispensing processing of the micromotor rotor, but also can realize automatic unloading with its own loading mechanism. After the dispensing is completed, it cooperates with the robot to automatically unload, making the entire dispensing process fully automated, thereby greatly improving the dispensing efficiency of the micromotor.

[0019] 2. When the micromotor rotor dispensing device is dispensing glue on the micromotor rotor, the entire micromotor rotor does not need to rotate at high speed to switch grooves or rotate at high speed to dispense glue on the rotor end face, thereby effectively avoiding the existing semi-automatic rotary dispensing machine from throwing out the glue that has not penetrated into the groove due to the action of centrifugal force during the rotor dispensing process, thereby effectively ensuring the effect of micromotor rotor dispensing and effectively guaranteeing the product quality of the prepared micromotor.

[0028] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Figures 1 to 7 , and describes the application in detail with reference to embodiments. Example 1

[0030] Example 1 provides a micromotor rotor omnidirectional glue dispensing device, refer to the attached Figure 1 and attached Figure 2 The main structure of the dispensing device includes a chassis 1 and a glue liquid box 3, and a turntable seat 4 is fixedly provided on the upper surface of the chassis 1.

[0031] Reference Attachment Figure 3 and attached Figure 4 A circular groove 401 is provided on the upper surface of the turntable seat 4, and a plurality of arc-shaped tooth surfaces 402 are evenly arranged circumferentially on the inner wall of the circular groove 401. The specific number of the arc-shaped tooth surfaces 402 is determined by the number of grooves on the micromotor rotor, and a bearing 403 is provided at the center of the bottom wall of the circular groove 401. A vertical shaft 404 is rotatably connected in the bearing 403. The upper end of the vertical shaft 404 is connected to the turntable 5. A driving motor (not shown in the figure) connected to the lower end of the vertical shaft 404 is provided in the chassis 1. In order to achieve the effect of fixed-angle rotation, the driving motor is preferably a stepping motor. The fixed-angle rotation of the driving motor is controlled by controlling the pulse signal of the stepping motor, so that the turntable 5 rotates at a fixed angle in the circular groove 401 to achieve the station switching effect of the micromotor rotor.

[0032] Reference Attachment Figure 4 and attached Figure 5The turntable 5 is provided with a plurality of stepped circular holes in a circular array. A rotor holder 501 is inserted into each stepped circular hole. The rotor holder 501 is also shaped like a stepped cylinder, allowing it to rotate within the stepped circular hole. A positioning slot 502 for inserting the rotor is provided on the upper surface of the rotor holder 501. A gear 503 is connected to the lower end of the rotor holder 501, extending below the turntable 5. The outer end of the gear 503 is aligned with the arcuate tooth surface 402 on the inner wall of the circular rotating slot 401. During the rotation of the turntable 5, when the rotor holder 501 rotates to the position of the arcuate tooth surface 402, the meshing action between the gear 503 and the arcuate tooth surface 402 causes the rotor holder 501 to rotate within the stepped circular hole. To control the rotation angle of the rotor holder 501, the number of teeth on the gear 503 can be set to n times the number of teeth on the arcuate tooth surface 402 according to actual conditions. Taking the micromotor rotor to be dispensed as an example, which has four grooves, the number of teeth on the gear 503 can be set to four times the number of teeth on the arc-shaped tooth surface 402. When the rotor holder 501 rotates with the turntable 5, the rotor holder 501 can rotate 90° every time it passes through an arc-shaped tooth surface 402, thereby controlling the rotation switching of the grooves on the micromotor rotor.

[0033] Reference Attachment Figure 1 , Attachment Figure 2 and attached Figure 6 , a plurality of groups of groove dispensing mechanisms 6 are provided on the chassis 1. The specific number of groove dispensing mechanisms 6 is determined by the number of grooves of the micromotor rotor to be dispensed. Taking the above-mentioned four-groove rotor as an example, the groove dispensing mechanisms 6 in this embodiment are provided in four. The four groove dispensing mechanisms 6 are arranged in a circular array on the upper surface of the chassis 1 outside the turntable seat 4. The groove dispensing mechanism 6 includes a stand 601 fixedly provided on the upper surface of the chassis. A vertical slide 602 is provided on the side of the stand 601 facing the turntable seat 4. A slide 603 is provided in the vertical slide 602. A telescopic device 605 is provided at the top of the stand 601. The telescopic device 605 can be a cylinder or a hydraulic telescopic rod.

At the same time, a first glue dispensing gun head 604 is fixedly connected to the outside of the slide 603, and the lower end of the first glue dispensing gun head 604 is connected to a first glue discharge needle tube 606 set downwardly inclined, and the upper end of the first glue dispensing gun head 604 is connected to a first glue delivery pipe 607, and the end of the first glue delivery pipe 607 is connected to the first glue delivery pump 608 on the glue liquid tank 3, and the feed end of the first glue delivery pump 608 is connected to the interior of the glue liquid tank 3.

[0034] Reference Attachment Figure 1 , Attachment Figure 2 and attached Figure 7A rotor end surface dispensing mechanism 7 is also provided on the chassis 1. The rotor end surface dispensing mechanism 7 is provided with a, which can be arbitrarily arranged on the upper surface of the chassis 1 outside the turntable seat 4. The rotor end surface dispensing mechanism 7 includes an L-shaped frame 701, and a rotary motor 702 is provided at the upper end of the L-shaped frame 701. In order to facilitate the control of the rotary motor 702 between forward and reverse rotation, the rotary motor 702 is preferably a servo motor, and a connecting block 703 is connected to the lower end of the output shaft of the rotary motor 702. The connecting block 703 is connected to a second dispensing gun head 704 through an oblique bar. The lower end of the second dispensing gun head 704 is connected to a second glue dispensing needle tube 705 that is tilted downward. The driving action of the rotary motor 702 causes the lower end of the second glue dispensing needle tube 705 to rotate around the center of the upper end face of the micromotor rotor for one circle, thereby evenly dispensing glue on the outer periphery of the micromotor rotor shaft. A second glue delivery tube 706 is connected to the upper end of the second glue gun head 704. The end of the second glue delivery tube 706 is connected to the second plastic pump on the glue tank 3. In addition, since the second glue delivery tube 706 rotates one circle with the second glue gun head 704 each time, a corrugated telescopic end 707 is provided at one end to prevent it from getting tangled, giving it a certain degree of elasticity. Example 2

[0035] Example 2 provides a micro-motor rotor dispensing device that can automatically load materials. The device is based on Example 1 and adds a set of automatic loading mechanism 2. The similarities between it and Example 1 are not described again. The differences between this Example 2 and the attached Figure 1 and attached Figure 2 Explain it.

[0036] The automatic loading mechanism in Example 2 includes a conveyor track 201 connected to a vibrating loading tray (not shown). The upper end of the conveyor track 201 is open, and the lower end is connected to a vertical support frame 202. Support bars 203 are installed on the inner walls of the conveyor track 201, with a gap between the two support bars 203 to guide the lower end of the rotor. A discharge channel 204 is connected to the end of the conveyor track 201, and the lower end of the discharge channel 204 is positioned directly opposite the positioning slot 502 in the rotor holder 501.

[0037] In addition, a material discharging motor 206 is provided on the vertical support frame 202 close to the side of the chassis 1, and the upper end of the output shaft of the material discharging motor 206 is connected to the material discharging disk 205, and a plurality of arc-shaped material discharging grooves are evenly arranged on the outer circular surface of the material discharging disk 205, and a notch is provided on the side of the conveying track 201, and one end of the material discharging disk 205 is extended into the conveying track 201 through the notch.

[0038] During the dispensing process of the micromotor rotor, the micromotor rotor is sent into the conveying track 201 by the vibrating loading plate, and then the dispensing plate 205 is driven to rotate a certain angle by the dispensing motor 206. During the rotation of the dispensing plate 205, one micromotor rotor can be moved into the discharge channel 204 at a time through the arc-shaped dispensing groove, and then the micromotor rotor falls accurately into the positioning groove 502 of the rotor holder 501 along the discharge channel 204.
