Description

Motor rotor iron core magnetic steel automatic packaging equipment

The invention relates to a production equipment for a rotor iron core of a motor, and more particularly to an automatic packaging equipment for the magnetic steel of a rotor iron core of a motor.

The rotor orientation of the motor requires a large output capacity, and at the same time has high requirements for environmental conditions (high speed, high and low temperature, oiliness, corrosiveness, etc.). The combination of the multilayer iron core and the firmness of the magnetic steel in the rotor core will directly affect the performance of the motor. Output efficiency and quality, life span.

At present, the iron core and magnetic steel are encapsulated by the magnetic steel sealing glue host of the motor rotor iron core. The current sealing methods are roughly divided into three types. The first is the dispensing and fixing method: the magnetic steel is first loaded into the iron core magnetic steel In the tank, apply liquid filled hot plastic dots on the surface of the magnetic steel and its surroundings, so that it will automatically flow into the gap; the second method is the magnetic steel immersion method: first paste a film on the bottom of the iron core and inject an appropriate amount The liquid thermosetting glue is placed in the magnetic steel tank, and then the magnetic steel is put into the magnetic steel tank; the third is the single-particle glue filling method: first arrange and fill the iron core and the magnetic steel, and then heat the single The solid rubber particles are applied with a heat source to melt them, and force is applied to squeeze the molten rubber into the magnetic steel groove, so that it is filled in the gap between the magnetic steel and the magnetic steel groove.

Comparing the three sealing methods of the above sealing host, the first and second methods are only suitable for single-layer iron cores and liquid filling glue, and the manual participation is high; these two methods do not have multilayer iron cores and The condition of automatic production and the lack of pressure during the filling process may cause the glue structure to be loose. Although the third method can produce multi-layer iron core rotors, the single rubber particles are not easy to be uniformly heated due to their large volume; in automated production, the rubber particles need to be preheated for a long time in advance, so the filling quality is relatively uneven , And its single source of glue leads to a long flow channel, the actual usage rate of rubber particles is too low, and the cost is high; therefore, the above-mentioned sealing method cannot achieve mass production of high-quality and high-capacity motor rotors.

At the same time, the existing glue sealing host usually adopts the glue injection method.

The function drops and cannot be accurately grasped and collected; therefore, the glue injection equipment using the existing sealing host can only realize the automation of the glue injection process, and the continuous supply of iron core, the supply of rubber pellets, and the collection of waste materials can be used in the entire production The overall automation cannot be achieved in the process.

As shown in Figures 1 to 3, the automatic packaging equipment 100 for a motor rotor iron core magnetic steel according to an embodiment of the present invention includes: at least one packaging host 1, a waste removal device 2, a rubber pellet supply device 3, and a control Device 4 and a conveying device 5.

As shown in FIG. 4, the packaging host 1 includes a glue injection mechanism 11 and a rotor core feeding mechanism 12. The glue injection mechanism 11 is used to inject glue into the rotor core M. In this embodiment, the glue is injected upward from the bottom of the rotor core M. The rotor core feeding mechanism 12 is arranged on one side of the glue injection mechanism 11 to feed the plurality of rotor cores M into the glue injection mechanism 11 one by one.

In this embodiment, the rotor core feed mechanism 12 is a rotary feed. The rotor core feeding mechanism 12 includes a rotating shaft 121, a power output member 122 and a rotor core carrier 123. The rotating shaft 121 is arranged on one side of the glue injection mechanism 11, the center of the rotor core carrier 123 is sleeved on the rotating shaft 121, the rotor core carrier 123 is provided with a plurality of glue injection plates 1231, and each glue plate 1231 is respectively provided There is a placement area R for placing a rotor core M (refer to Figure 10). In the placement area R, the glue injection board 1231 is also provided with a plurality of glue injection holes 1232 to allow the glue injection mechanism 11 to pass through the glue injection board 1231 from below to inject glue into the rotor core M.

The power output member 122 is connected to the rotor core carrier 123 so that the rotor core carrier 123 rotates to feed the glue injection plate 1231 into the glue injection mechanism 11 sequentially. In this embodiment, the rotor core carrier 123 is double symmetrical, and each end is provided with a glue injection plate 1231. Therefore, every time the rotor core carrier 123 rotates 180 degrees, a rotor core M is fed into the glue injection mechanism 11.

With the continuous rotation of the rotor core carrier 123, the rotor core M to be injected can be automatically fed into the injection mechanism 11, and the completed rotor core M can be sent out of the injection mechanism 11. However, the present invention is not limited to this.

The movable frame 33 is connected to the rubber pipe 32, and the inlet of the rubber pipe 32 is connected to the rubber particle storage mechanism 31. The rubber particle storage mechanism 31 stores a plurality of rubber particles (not shown). The rubber particle storage mechanism 31 vibrates at a specific frequency to separate the rubber particles stacked in the rubber particle storage mechanism 31. The separated rubber particles pass through the rubber pipe 32 outputs. The outlet of the rubber pipe 32 faces the upper surface of the transfer tray 34. As shown in FIG. 7, the transfer tray 34 has a plurality of positions corresponding to the accommodating grooves 341 of the rotor core M. Therefore, when the movable frame 33 moves the rubber pipe 32 to each accommodating groove 341, the rubber particles output by the rubber pipe 32 will follow They are sequentially dropped into the accommodating groove 341, and temporarily stored in the transfer tray 34 in a manner that the arrangement pattern matches the glue injection position of the rotor core M. As shown in FIGS. 7 and 8, a control valve 342 is provided at the bottom of the transfer tray 34 to selectively control the opening and closing of the bottom of the containing tank 341. When the transfer tray 34 is located below the rubber pipe 32 to receive rubber pellets, the control valve 342 is closed to leave the rubber pellets in the holding tank 341; when the transfer tray 34 is moved to the glue injection mechanism 11, the control valve 342 opens to make the glue The pellets fall on the glue injection mechanism 11. In this embodiment, the control valve 342 has a plate-like structure with an opening, and the opening can be connected or disconnected from the receiving groove 341 through horizontal movement. However, the present invention is not limited to this, and the control valve 342 can have other structures and principle.

As shown in FIGS. 1 to 3, the conveying device 5 includes a conveying track 53, a first moving mechanism 51 and a second moving mechanism 52. The conveying track 53 is parallel to the connection line of the glue injection mechanism 11, the glue pellet supply device 3 and the waste removal area F. The first moving mechanism 51 is connected to the transfer tray 34 so that the transfer tray 34 slides on the conveying track 53 and is fed under the rubber pipe 32 and the glue injection mechanism 11, while the second moving mechanism 52 is connected to the waste removal device 2 so that The waste removal device 2 slides on the conveying track 53 and is fed into the waste removal area F and the glue injection mechanism 11.

As shown in FIG. 5, the control device 4 signals the glue injection mechanism 11, the power output member 122 of the rotor core feeding mechanism 12, the moving frame 33, the control valve 342, the waste removal device 2, the first moving mechanism 51 and the first moving mechanism 51. Two moving mechanism 52.

Next, it will be explained how the control device 4 controls these elements to work together.

First, the control device 4 controls the first moving mechanism 51 to move the transfer tray 34 so that the transfer tray 34 is located at a position corresponding to the colloidal pellet supply device 3. The first moving mechanism 51 can not only slide the transfer tray 34 along the conveying track 53, but also The first moving mechanism 51 can also move the transfer tray 34 back and forth in a direction perpendicular to the conveying track 53 so that the outlet of the rubber pipe 32 faces the transfer tray 34. Then the control device 4 controls the moving frame 33 to move the rubber pipe 32 horizontally, so that the rubber pipe 32 moves on the upper surface of the transfer tray 34 to place the rubber particles in the plurality of holding grooves 341. In this process, the control device 4 controls the control valve 342 closed.

On the other hand, the control device 4 controls the power output member 122 to rotate the rotor core carrier 123, and feed one of the glue injection plates 1231 and the rotor core M to be glued on it into the glue injection The upper part of the mechanism 11 is pre-note glue.

Next, the control device 4 controls the first moving mechanism 51 to move the transfer tray 34 so that the transfer tray 34 is moved to a position corresponding to the glue injection mechanism 11 via the conveying track 53 (the first moving mechanism 51 can be moved in a direction perpendicular to the conveying track 53 Move the transfer tray 34 back and forth so that the transfer tray 34 is located directly above the glue injection mechanism 11). At this time, the transfer tray 34 is located below the glue injection board 1231 and above the glue injection mechanism 11. The control device 4 controls the control valve 342 to open, so that the rubber particles fall down at a predetermined position and are supplied to the glue injection mechanism 11. By repeating the above actions, the transfer tray 34 can be moved back and forth between the position corresponding to the rubber particle storage mechanism 31 and the position corresponding to the glue injection mechanism 11, thereby continuously distributing the rubber particles at the predetermined position of the glue injection mechanism 11.

After the transfer tray 34 leaves, the control device 4 controls the glue injection mechanism 11 to move upward (or the rotor core carrier 123 moves down), so that the glue injection mechanism 11 is directed to the rotor core M through the glue injection hole 1232 of the glue injection plate 1231. Injection glue. Since the arrangement of the rubber particles distributed by the glue injection mechanism 11 corresponds to the glue injection position of the rotor core M, when the rotor core M is located directly above the glue injection mechanism 11, the glue injection mechanism 11 directly squeezes and heats these already placed The glue particles can be used to inject the melt into the rotor core M. During the glue injection process, the control device 4 can simultaneously control the first moving mechanism 51 and the moving frame 33 to perform the aforementioned rubber particle arrangement action.

After the glue injection is completed, the rotor core carrier 123 is separated from the glue injection mechanism 11 (the rotor core carrier 123 can be moved up or the glue injection mechanism 11 is moved down), and the control device 4 controls the second moving mechanism 52 to move the waste removal Device 2 moves the waste removal device 2 toward a position corresponding to the glue injection mechanism 11. The second moving mechanism 52 can move the waste removal device 2 back and forth in a direction perpendicular to the conveying track 53 so that the waste removal device 2 is located directly above the glue injection mechanism 11.

When the waste removal device 2 is located directly above the injection mechanism 11 at the position corresponding to the glue injection mechanism 11 (the waste removal device 2 is under the rotor core carrier 123 at this time), the control device 4 controls the waste removal device 2 Take out the waste glue remaining on the glue injection mechanism 11. In this embodiment, the waste removal device 2 is a suction head that uses suction to suck waste rubber, but the invention is not limited to this.

After sucking the waste rubber, the control device 4 then controls the second moving mechanism 52 to move the waste removal device 2 to move the waste removal device 2 to the waste removal area F. The rotor core M that has been injected with glue is removed and replaced with the next one, and the next rotor core M to be injected with glue is fed into the glue injection mechanism 11.

When the waste removal device 2 is moved to a position corresponding to the waste removal area F, the control device 4 controls the waste removal device 2 to release waste rubber, so that the waste rubber falls in the waste removal area F. By repeating the above actions, the waste removal device 2 can be moved back and forth between the position corresponding to the waste removal area F and the position corresponding to the glue injection mechanism 11, and the waste glue remaining in production can be automatically and continuously removed.

The sequence of the operation steps of the automatic packaging equipment 100 for the motor rotor iron core magnetic steel of the present invention is actually not limited to the above. In fact, the sequence of the actions of the components can be adjusted according to the process conditions.

Through the motor rotor iron core magnetic steel automatic packaging equipment 100 of the present invention, under the coordinated control of the control device 4, the rotor iron core feeding mechanism 12 can be driven to move, and the rotor iron core M can be fed into the glue injection mechanism periodically; and At the same time, the rubber particle storage mechanism 31 separates and outputs the rubber particles by shaking, and transports the rubber particles in groups through the rubber pipe 32 to the corresponding holding tank 341 for temporary storage; this step uses small rubber particles to achieve the The pre-arrangement can effectively avoid the problems of long preheating time of large rubber particles, uneven filling quality, and low actual utilization rate of rubber particles, and effectively reduce the use cost of rubber particles. The transfer tray 34 is pushed to the top of the glue injection mechanism 11 by the first moving mechanism 51, and is filled into the glue injection mechanism 11 by the opening and closing of the control valve 342; after the glue injection is completed, the glue waste removal device 2 With the cooperation of the second moving mechanism 52, the waste rubber is transferred to the waste removal area F, and the rotor core feeding mechanism 12 transports out the rotor core M that has completed the injection, thereby realizing the automatic cleaning of the waste rubber.

The automatic magnetic steel packaging equipment 100 of the motor rotor iron core of the present invention completes the automatic supply of the rotor core M, the automatic supply of rubber particles, and the automatic removal of waste rubber, and achieves the automatic operation of the entire production process, thereby prompting the rotor core M Automated mass production. The automatic magnetic steel packaging equipment 100 of the motor rotor iron core of the present invention can automatically inject glue to the multilayer iron core, ensure the combination of the multilayer iron core and the firmness of the magnetic steel in the rotor iron core, and further improve the quality and capacity of the motor rotor.

The heat preservation member 124 includes a lifting arm 1241, a heat preservation cover 1242 and a heating chassis 1243. The lifting arm 1241 is connected to the heat preservation cover 1242, the heating chassis 1243 is disposed under the heat preservation cover 1242, and the control device 4 is connected to the lifting arm 1241 by signals to control the vertical displacement of the lifting arm 1241. When a glue injection plate 1231 and the rotor core M on it are located in the glue injection mechanism 11, the control device 4 can control the lifting arm 1241 to descend, so that the thermal insulation member 124 covers the other glue injection mechanism 11 and waits for injection. The rubber rotor core M, and the heating chassis 1243 is located directly below the glue injection board 1231 that has not been fed. The thermal insulation member 124 and the heating chassis 1243 sandwich the rotor core M to provide continuous thermal insulation for the rotor core M waiting for glue injection, so that the temperature is close to the conditions required by the manufacturing process, so as to improve the subsequent glue injection quality.

Further, in one embodiment, as shown in FIGS. 10 to 12A, the automatic packaging equipment 100 for the magnetic steel of the motor rotor iron core of the present invention further includes a shaft-piercing device 6. The piercing and expanding shaft device 6 includes an outer sleeve 61, an inner sleeve 62, a threading shaft 63, an extrusion power member 64 and a reset power member 65.

As shown in FIGS. 11 to 12C, the inner sleeve 62 has a conical shape, and the bottom end of the inner sleeve 62 is connected to the rubber injection plate 1231 of the rotor core feeding mechanism 12.

As shown in FIGS. 10 and 12A, the outer surface of the outer sleeve 61 faces the inner surface of the shaft hole, and as shown in FIG. 10, the outer sleeve 61 has a plurality of upper grooves 611 and a plurality of lower grooves 612.

Next, how to manipulate the outer diameter size change of the outer sleeve 61 will be explained.

As shown in Fig. 12A, first, the shaft hole of the rotor core M is aligned with the shaft-piercing device 6 and inserted. When the outer sleeve 61 is not expanded, the outer sleeve 61 is not in close contact with the inner surface of the shaft hole of the rotor core M. It should be noted that FIGS. 12A to 12C are for ease of understanding. Therefore, the distance between the outer sleeve 61 and the inner surface of the shaft hole is exaggerated. In fact, the actual size and proportion of each component may not be the same as the drawing.

Next, as shown in FIG. 12B, the control device 4 controls the pressing power member 64 to press the head 631 along the axial direction of the shaft 63, and the head 631 presses the outer sleeve 61 in the accommodating groove T so that the outer sleeve 61 is slightly stretched outwards under force, and the outer diameter increases.

When the rotor core M is to be taken out, as shown in FIG. 12C, the control device 4 controls the resetting power member 65 to press the body 632 in the axial direction of the through shaft 63 in reverse direction, so that the through shaft 63 is pushed up to prevent it from falling out. For the part 613, since the outer sleeve 61 receives an upward force, the outer diameter is retracted to its original size. Thereby, the distance between the outer sleeve 61 and the inner surface of the shaft hole of the rotor core M is increased, so that the rotor core M can be easily taken out.
