[0028] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings.

[0029] Combined Figures 1-9 As shown in FIG. 1, a motor magnetic ring automatic assembly equipment 10 comprises a casing turnover feeding module 1000, a magnetic ring feeding module 2000, a jig backflow conveying device 3000 and a magnetic ring pressing device 4000. The casing turnover feeding module 1000, the magnetic ring feeding module 2000 and the magnetic ring pressing device 4000 are arranged around the periphery of the jig backflow conveying device 3000. The jig backflow conveying device 3000 is provided with a plurality of loading jigs 3100 and a feeding area. When one of the loading jigs 3100 is located on the feeding area, the magnetic ring feeding module 2000 is used to move the magnetic ring to the loading jig 3100 on the feeding area, the casing turnover feeding module 1000 is used to move the casing to the feeding area so that the casing is sleeved on the magnetic ring, and when the loading jig 3100 is moved to the magnetic ring pressing device 4000 by the jig backflow conveying device 3000, the magnetic ring pressing device 4000 is used to press and hold the magnetic ring and the casing on the loading jig 3100.

[0030] It needs to be explained that the carrier jig 3100 includes a bearing block 3110 and a positioning boss 3120, the positioning boss 3120 is arranged on the bearing block 3110, and a positioning protrusion is further arranged on the positioning boss 3120, and a positioning hole is arranged on the positioning protrusion. The upper magnetic ring module 2000 carries the magnetic ring to the feeding area, and sets the magnetic ring sleeve on the positioning protrusion, and limits and fixes the magnetic ring through the positioning protrusion. Then, the casing is carried to the feeding area by the casing overturning and feeding module 1000, and the casing is sleeved on the magnetic ring, and the shaft on the casing is located in the positioning hole, and the shaft is limited by the positioning hole. At this time, the magnetic ring has not been completely installed, so the magnetic ring and the casing on the carrier jig 3100 are moved to the magnetic ring pressing device 4000 by the jig backflow conveying device 3000, and the magnetic ring and the casing are pressed by the magnetic ring pressing device 4000. The magnetic ring can be completely installed in the inner cavity of the casing. In this way, the automatic feeding, positioning and assembly of the magnetic ring and the casing can be realized, the high-efficiency and high-precision magnetic ring assembly can be realized, and the stability of the product assembly quality can be ensured.

[0031] Please refer to Figure 2 and Figure 3 As shown in the figures, in order to ensure the firmness of the magnetic ring after the magnetic ring and the casing are assembled, a gluing operation needs to be performed on the inner side wall of the casing before the magnetic ring is assembled into the casing. The traditional gluing method is to use a glue gun to glue manually. However, this gluing method is not only slow in efficiency, but also cannot control the amount of glue used, which may result in uneven glue coating or excessive glue coating and waste. Therefore, the motor magnetic ring automatic assembly equipment 10 further includes a casing gluing device 5000, which is arranged on one side of the casing overturning and feeding module 1000 and is used for gluing the inner side wall of the casing.

[0032] The motor magnetic ring automatic assembly equipment 10 further includes a base 6000, and the casing gluing device 5000 is arranged on the base,

[0033] Specifically, the casing gluing device 5000 comprises a rotating jig 5100, a gluing support 5200 and a gluing piece 5300. The rotating jig 5100 is arranged on the base 6000, the gluing support 5200 is arranged on one side of the base, and the gluing piece 5300 is arranged on the gluing support 5200 in an inclined manner. The glue outlet of the gluing piece 5300 is arranged towards the inner side wall of the casing on the rotating jig 5100. When the casing is placed on the rotating jig 5100, the rotating jig 5100 is used to drive the casing to rotate, and the gluing piece 5300 is used to glue the inner side wall of the casing. That is, the casing is carried to the rotating jig 5100 by the corresponding carrying manipulator, and is fixed by the rotating jig 5100. At the same time, when the rotating operation is performed, the casing is driven to rotate by the rotating jig 5100. In this way, the gluing piece 5300 can surround the inner side wall of the casing and perform gluing operation, so that the glue can be uniformly coated on the inner side wall of the casing.

[0034] Further, in the gluing operation of the casing, the conventional fixing method of the casing is to directly clamp and fix the casing by the clamping jaw. However, since the clamping jaw needs to be constantly loosened and clamped every time the gluing operation is performed, a certain production time is occupied, which leads to slow production efficiency. In addition, the casing is clamped and fixed by the clamping jaw, which is easy to cause the casing to be damaged and deformed due to uneven stress.

[0035] Therefore, in the embodiment, the rotating jig 5100 comprises a rotating positioning piece 5110, a suction member 5120 and a rotating driving piece 5130. The rotating positioning piece 5110 is arranged on the base 6000, and the avoiding hole 5111 is arranged on the rotating positioning piece 5110. The suction member 5120 is arranged in the avoiding hole 5111. When the casing is placed on the rotating positioning piece 5110, the suction member 5120 is used to adsorb and fix the casing. The rotating driving piece 5130 is connected with the rotating positioning piece 5110, and is used to drive the rotating positioning piece 5110 to rotate. That is, when the casing is placed on the rotating positioning piece 5110, the casing is limited by the rotating positioning piece 5110, and is adsorbed and fixed by the suction member 5120 to ensure the stability of the casing during the rotation. In this way, by using the adsorption method, the time of constantly loosening and clamping the clamping jaw can be reduced compared with the existing clamping method, so as to improve the production efficiency, and the problem of the casing being damaged and deformed due to uneven stress can be avoided. Preferably, the rotating driving piece 5130 is a rotating motor.

[0036] Specifically, the rotating positioning member 5110 comprises a rotating fixing block 5112, a rotating positioning block 5113 and a bearing 5114, the rotating fixing block 5112 is connected with the rotating driving member 5130, the rotating positioning block 5113 is arranged on the rotating fixing block 5112, the bearing 5114 is sleeved on the rotating fixing block 5112, and the avoiding hole 5111 is arranged on the rotating positioning block 5113, and the suction member 5120 is located in the avoiding hole 5111. In this way, the rotating axial force of the rotating fixing block 5112 is borne by the bearing 5114, so that the rotating stability of the rotating positioning block 5113 can be ensured, and the service life of the whole device can be further improved.

[0037] Further, the rotating positioning block 5113 is provided with a positioning hole 5113a, when the shell is placed on the rotating positioning block 5113, the rotating shaft on the shell is located in the positioning hole 5113a, the suction member 5120 is used for adsorbing and fixing the bottom of the shell, and the positioning hole 5113a is used for avoiding and positioning the rotating shaft on the shell.

[0038] In the embodiment, the suction member 5120 comprises two adsorption magnets 5121, and each adsorption magnet 5121 is used for adsorbing and fixing the shell. Correspondingly, the avoiding hole on the rotating positioning block 5113 is also provided with at least two, so that each adsorption magnet 5121 can be accommodated in the avoiding hole.

[0039] Further, in order to avoid that the shell is scratched or bumped when being positioned and rotated, the rotating positioning block 5113 is made of non-metallic buffer material, for example, rubber material, so that the shell is prevented from being damaged in appearance quality due to collision with the rotating positioning block 5113.

[0040] In an embodiment, the glue applying member 5300 comprises a glue applying syringe 5310, a syringe fixing frame 5320 and a glue applying driving member 5330, the syringe fixing frame 5320 is slidingly arranged on the glue applying support 5200, the glue applying syringe 5310 is arranged on the syringe fixing frame 5320, the glue applying driving member 5330 is connected with the syringe fixing frame 5320, and the glue applying driving member 5330 is used for driving the syringe fixing frame 5320 to move towards the inner side wall of the shell. The glue applying syringe 5310 stores glue, and the glue dispensing needle of the glue applying syringe 5310 is inclined towards the inner side wall of the shell. The glue is extruded to the inner side wall of the shell by the glue applying syringe 5310. While the glue is applied by the glue applying syringe 5310, the rotating positioning block 5113 drives the shell to slowly rotate 360 degrees, so that the glue is uniformly applied to the four side walls of the shell. In the embodiment, the glue applying driving member 5330 is a pen-shaped air cylinder, which has small volume and occupies small space, so that the whole device is more compact and small.

[0041] In order to realize the automatic feeding of the shell, and further improve the automation degree of the whole device, the shell overturning and feeding module is arranged to automatically overturn and feed the shell.

[0042] Specifically, the shell overturning and feeding module 1000 comprises a shell overturning manipulator 1100 and a shell feeding manipulator (not shown in the figure), and the shell overturning manipulator 1100 and the shell feeding manipulator are arranged on one side of the jig reflow conveying device 3000. The shell overturning manipulator 1100 is used for overturning operation of the shell, and the shell feeding manipulator is used for moving the shell subjected to the overturning operation to the feeding area, so that the shell is sleeved on the magnetic ring. Since the inner side wall of the shell needs to be coated before the shell is subjected to the overturning and feeding operation, the opening of the shell is arranged upward. At the same time, since the shell assembled with the magnetic ring needs to be subjected to the magnetic ring pressing operation subsequently, if the opening of the shell is upward, the shell and the magnetic ring are easily pressed when the magnetic ring pressing operation is performed, which causes the position deviation. Therefore, the shell overturning manipulator 1100 is used to overturn the shell before the shell is fed, so that the opening of the shell is arranged downward. In this way, when the shell and the magnetic ring are subjected to the pressing operation, the magnetic ring pressing device directly presses the outer bottom surface of the shell, so that the pressing area is increased. Even if the position deviation occurs, the shell and the magnetic ring can be prevented from being pressed.

[0043] Further, please refer to Figure 4As shown, the shell overturning manipulator 1100 includes an overturning workpiece jig 1110, a fixed clamping jaw 1120, an overturning motor 1130, and a lifting member 1140. The overturning workpiece jig 1110 is located at one side of the jig reflow conveying device 3000. The fixed clamping jaw 1120 is connected with the overturning motor 1130. The lifting member 1140 is connected with the overturning motor 1130. The fixed clamping jaw 1120 is used for loading and fixing the shell on the overturning workpiece jig 1110. The overturning motor 1130 is used for driving the fixed clamping jaw 1120 to perform overturning operation, so that the opening of the shell is arranged downward. The lifting member 1140 is used for driving the overturning motor 1130 to perform lifting movement. In this way, the shell is positioned by the overturning workpiece jig 1110, which facilitates the clamping and fixing of the shell by the fixed clamping jaw 1120 and the overturning operation, and facilitates the clamping and loading operation of the shell by the shell loading manipulator. Further, in the embodiment, the lifting member 1140 includes a lifting plate 1141 and a driving cylinder 1142. The overturning motor 1130 is arranged on the lifting plate 1141. The driving cylinder 1142 is connected with the lifting plate 1141. The driving cylinder 1142 is used for driving the lifting plate 1141 to perform lifting movement. In this way, the overturning operation of the shell can be realized by the lifting member 1140, the fixed clamping jaw 1120, and the overturning motor 1130. Specifically, the optical fiber sensor is installed on the overturning workpiece jig 1110. Whether the shell is placed on the overturning workpiece jig 1110 is identified by the optical fiber sensor. Meanwhile, the optical fiber sensor is also installed on the overturning motor 1130. Whether the shell is clamped on the fixed clamping jaw 1120 is identified by the optical fiber sensor installed on the overturning motor 1130, so as to control the start of the overturning motor. In this way, the overturning operation of the whole device is more coherent and compact. Further, in the embodiment, the shell loading manipulator is a three-axis manipulator.

[0044] In order to realize the automatic loading of the magnetic ring and further improve the automation degree of the whole device, the magnetic ring is automatically loaded by the upper magnetic ring module 2000.

[0045] Specifically, the upper magnetic ring module 2000 includes a discharge disc and a magnetic ring carrying manipulator. The discharge disc is arranged at one side of the magnetic ring carrying manipulator, and the magnetic ring carrying manipulator is located at one side of the jig reflow conveying device 3000. The magnetic ring is stored on the discharge disc. The discharge disc continuously discharges, and the magnetic ring carrying manipulator continuously carries the magnetic ring to the loading jig in the loading area. For example, the discharge disc is a vibrating disc, and the magnetic ring carrying manipulator can adopt a three-axis manipulator.

[0046] In order to avoid the position deviation of the magnetic ring relative to the shell after the shell and the magnetic ring are loaded, which affects the normal work of the magnetic ring pressing device, in the present application, please refer to Figure 8As shown, the motor magnetic ring automatic assembly equipment 10 further comprises a magnetic ring placement defect detection device 7000, which is arranged on the jig backflow conveying device 3000 and located between the loading area and the magnetic ring pressing device 4000. The magnetic ring placement defect detection device 7000 is used for detecting the position of the magnetic ring on the loading jig 3100. For example, the magnetic ring placement defect detection device 7000 is an optical fiber displacement sensor, which can detect the position of the magnetic ring to avoid the problems of missing placement or offset placement of the magnetic ring.

[0047] As shown in Figure 5 and Figure 6 Before the magnetic ring pressing operation is performed, the magnetic ring and the shell are only aligned, but the magnetic ring has not been completely installed. Therefore, the magnetic ring pressing device is needed to press the magnetic ring to ensure that the magnetic ring is installed in place.

[0048] Specifically, the magnetic ring pressing device 4000 comprises a fixing frame 4100, a pressing driving member 4200 and an elastic pressing member 4300. The fixing frame 4100 is arranged on one side of the jig backflow conveying device 3000. The pressing driving member 4200 is installed on the fixing frame 4100 and connected with the elastic pressing member 4300. When the loading jig 3100 moves the magnetic ring and the shell to the lower side of the elastic pressing member 4300, the pressing driving member 4200 drives the elastic pressing member 4300 to move towards the shell, so that the elastic pressing member 4300 presses the shell and the magnetic ring. In this way, the magnetic ring can be installed in place. In this embodiment, the pressing driving member 4200 is a sliding table air cylinder.

[0049] Further, the elastic pressing member 4300 comprises a fixing block 4310, a first spring 4320, a fixing rod 4330 and a pressing block 4340. The fixing block 4310 is connected with the driving end of the pressing driving member 4200. The fixing rod 4330 is arranged in the fixing block 4310. The pressing block 4340 is connected with one end of the fixing rod 4330. The first spring 4320 is sleeved on the fixing rod 4330 and located between the fixing block 4310 and the pressing block 4340. The first spring 4320 can buffer the pressing force to avoid the magnetic ring and the shell being pressed.

[0050] In an embodiment, in order to enable the adhesive on the shell to quickly solidify, avoid the problem that the magnetic ring falls off due to the adhesive not being solidified when subsequent discharging of the shell is performed, the motor magnetic ring automatic assembly equipment of the present application further comprises a glue coating catalyst device 8000, which is arranged on the fixing frame and is used for performing glue coating catalyst operation on the magnetic ring on the loading jig.

[0051] It should be noted that the glue coating catalyst device 8000 is arranged opposite to the magnetic ring pressing device 4000, and the glue coating catalyst device 8000 needs to be performed before the magnetic ring pressing operation, that is, a layer of glue catalyst is coated on the outer surface of the magnetic ring on the loading jig 3100 before the magnetic ring pressing operation is performed, and then the magnetic ring pressing operation is performed to enable the magnetic ring to be completely installed into the inner cavity of the shell. At this time, the glue catalyst on the magnetic ring reacts with the adhesive on the inner side wall of the shell, so that the adhesive is accelerated to solidify, thereby avoiding the problem that the magnetic ring falls off when the shell is discharged. Specifically, in the present embodiment, the structure of the glue coating catalyst device 8000 is the same as that of the shell glue coating device. Further, in order to enable the outer surface of the magnetic ring on the loading jig 3100 to be coated with a layer of glue catalyst around the four sides, a rotary driving structure 3600 is arranged on the jig return conveying device 3000, for example, the structure of the rotary driving structure is the same as that of the rotary driving member 5130. The rotary driving structure is connected with the loading jig 3100, so as to realize the rotary movement of the loading jig 3100, and further drive the magnetic ring and the shell to rotate, so that the glue coating catalyst device 8000 can perform glue coating catalyst operation on the outer circumferential wall of the magnetic ring.

[0052] Please refer to Figure 5 and Figure 7 In an embodiment, in order to improve the assembly quality of the magnetic ring and the shell, ensure that the position of the magnetic ring does not deviate, and avoid the problem that the magnetic ring is not completely assembled in place during the magnetic ring pressing operation, the motor magnetic ring automatic assembly equipment further comprises a shaping device 9000. Specifically, the shaping device 9000 comprises a shaping support 9100, a shaping driving member 9200, a shaping sliding plate 9300, and a shaping member 9400. The shaping support 9100 is arranged on the jig return conveying device 3000. The shaping sliding plate 9300 is slidingly arranged on the shaping support 9100. The shaping driving member 9200 is connected with the shaping sliding plate 9300. The shaping member 9400 is arranged on one end of the shaping sliding plate 9300 which faces the jig return conveying device 3000. The shaping driving member 9200 is used to drive the shaping sliding plate 9300 to move towards the loading jig 3100, so as to enable the shaping member 9400 to perform downward shaping operation on the shell and the magnetic ring on the loading jig 3100, thereby ensuring that the position of the magnetic ring does not deviate and the like, and improving the assembly quality.

[0053] Further, the shaping member 9400 comprises a guide rod 9410, a second spring 9420 and a shaping block 9430, the guide rod 9410 is arranged on the shaping slide plate 9300, the shaping block 9430 is arranged on one end of the guide rod 9410 towards the jig backflow conveying device 3000, the second spring 9420 is sleeved on the guide rod 9410, and the second spring 9420 is located between the shaping slide plate 9300 and the shaping block 9430. The second spring 9420 plays a role of buffering the downward pressure, so as to avoid that the downward pressure is too large and the shell is pressed and injured. In order to avoid the shaft on the shell, the avoiding hole is also arranged on the shaping block 9430, and in the embodiment, the diameter of the avoiding hole should be greater than the diameter of the shaft, for example, greater than 2mm, so as to compensate the offset value of the position offset of the shaping block, so as to avoid the position offset of the shaping block, and further avoid that the shaft is pressed and injured.

[0054] The conventional conveying device is usually a one-way belt conveyor, and the conveying device cannot realize the backflow of the jig, that is, the material tray or the jig loaded with the material needs to be placed on the belt conveyor by the artificial or mechanical hand, and the material is conveyed by the belt conveyor. After the material is carried away by the unloading mechanical hand, the empty material tray or the empty jig on the belt conveyor also needs to be taken away by the artificial or mechanical hand, and the material is placed on the belt conveyor again. Thus, the cycle is repeated, and the one-way conveying mode is low in efficiency. Therefore, the jig backflow conveying device is adopted to solve the problem of conveying the jig backflow, and the artificial or mechanical hand is replaced to carry the jig, so as to improve the production efficiency, and the jig can also be avoided from being damaged by frequent carrying.

[0055] Please refer to Figure 8 and Figure 9 , and specifically, the jig backflow conveying device 3000 is provided with a plurality of material loading jigs 3100, and the jig backflow conveying device 3000 is provided with a material loading area, and the jig backflow conveying device 3000 is also provided with a magnetic ring pressing area and a shaping area; the jig backflow conveying device 3000 comprises a multi-station conveying module 3200, a first jig backflow module 3300, a jig transition module 3400 and a second jig backflow module 3500, and the multi-station conveying module 3200, the first jig backflow module 3300, the jig transition module 3400 and the second jig backflow module 3500 are sequentially connected in a ring shape.

[0056] It should be noted that the loading area, the magnetic ring pressing area and the shaping area are arranged on the multi-station conveying module 3200 in sequence, the magnetic ring pressing device 4000 is located on the magnetic ring pressing area, and the shaping device 9000 is located on the shaping area. In this way, the shell and the magnetic ring are sequentially subjected to loading, magnetic ring pressing and shaping on the multi-station conveying module 3200. The shell and the magnetic ring subjected to the above operations continue to enter the first jig reflow module 3300 with the loading jig 3100. The loading jig 3100 gradually passes through the first jig reflow module 3300 and the jig transition module 3400, and is finally transferred to the second jig reflow module 3500. A discharging robot or the like can be arranged on one side of the second jig reflow module 3500 to perform discharging operation on the product, and the empty loading jig 3100 continues to flow back to the multi-station conveying module 3200.

[0057] In an embodiment, the multi-station conveying module 3200 includes a first conveying belt 3210 and a first limiting stopper 3220.
