Description

Technical Field

[0001] This technical solution relates to the technical field of motor assembly equipment, specifically referring to a motor assembly feeding device. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (i.e., the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magnetoelectric driving rotating torque. A motor mainly consists of a stator and a rotor. The direction of the force on the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic induction line (magnetic field direction). The working principle of the motor is the action of the magnetic field on the current, which makes the motor rotate.

[0003] Currently, for motor assembly in the market, the stator, rotor, and end cap need to be installed inside the cylinder. The wires of the stator need to pass through the end cap, which makes it difficult for automated production. Before actual assembly, the staff passes the wires of the stator through the end cap and stacks them for the manipulator to pick up. When picking up, the end cap and the stator need to be moved, and during the movement, it is necessary to ensure that the wires are always inside the end cap. If the wires come out of the end cap, it will affect the subsequent assembly. Therefore, there is an urgent need for a fully automated motor assembly device to save manpower. Summary of the Invention

Detailed implementation manners

[0025] The following further elaborates in detail on the specific implementation manners of the technical solution in conjunction with the drawings.

[0026] The feeding device of the present application is a device used in the production of motor equipment, which is used to press-fit the stator 100 into the barrel 300, and at the same time feed the end cover 200 to the side of the barrel 300 to prepare for subsequent processing, saving processing steps. During the process of feeding the stator and the end cover, the stator and the end cover are stored in the stator end cover feeding tray in a stacked state. The stacked state means that the end cover is placed above the stator and the wiring of the stator passes through the through hole of the end cover. During the subsequent feeding process, regardless of the positions of the stator and the end cover, it is necessary to ensure that the wiring is always located within the through hole.

[0027] As Figure 1 and Figure 2 shown, a motor assembly feeding device includes a main frame 1, a stator end cover conveying mechanism 2, a stator pressing mechanism 3, and an end cover transfer mechanism 4. The stator end cover conveying mechanism 2, the stator pressing mechanism 3, and the end cover transfer mechanism 4 are all arranged on the main frame 1. The stator end cover conveying mechanism 2 is used to receive the externally placed stator and end cover in a stacked state and transfer the stator and the end cover; the stator pressing mechanism 3 is used to grasp the stator and press it into the barrel; the end cover transfer mechanism 4 is used to grasp the end cover and place it beside the barrel; during the conveying process of the stator and the end cover by the stator end cover conveying mechanism 2 and during the operation of the stator pressing mechanism 3 and the end cover transfer mechanism 4, it is always ensured that the wiring of the stator is located within the through hole of the end cover.

[0028] As Figure 3As shown in the figure, the stator end cover conveying mechanism 2 includes a conveying frame 21, conveying slide rails 22, conveying sliders 23 and a conveying driving member 24. The conveying frame 21 is arranged on the main frame 1; the number of the conveying slide rails 22 is set to two, and they are symmetrically arranged on the left and right sides of the conveying frame 21; the number of the conveying sliders 23 is set to several, and they are respectively movably arranged on the conveying slide rails 22; the conveying driving member 24 is fixedly arranged on the conveying frame 21, and the output end of the conveying driving member 24 is connected to the conveying slider 23; the conveying driving member 24 can drive the conveying slider 23 to horizontally move the stator and the end cover on the conveying slide rails 22. There is a placement position on the conveying slider 23, and the placement position is used to receive and limit the externally placed stator and end cover. The placement position can be formed by depression or protrusion on the conveying slider 23. A limiting block 25 is arranged on the end side of the conveying frame 21, and the limiting block 25 is used to limit the maximum moving distance of the conveying slider 23. When the end side of the conveying slider 23 abuts against the limiting block 25, it is the maximum moving distance of the conveying slider 23, which can ensure the stability of the mechanism operation.

[0029] As Figure 4 shown in the figure, the stator press-fitting mechanism 3 includes a press-fitting driving member 31, a press-fitting mounting plate 32, a stator press-fitting part 33 and a stator inner support 34. The stator press-fitting mechanism 3 can not only grasp the stator, but also press-fit the stator into the cylinder. The stator press-fitting mechanism 3 can perform vertical lifting. The press-fitting driving member 31 is arranged on the main frame 1; the press-fitting mounting plate 32 is arranged at the output end of the press-fitting driving member 31; the stator press-fitting part 33 is arranged on the press-fitting mounting plate 32; the stator inner support 34 is arranged on the press-fitting mounting plate 32. When the stator end cover conveying mechanism 2 conveys the stator and the end cover to the specified position, the end cover transfer mechanism 4 first grabs the end cover and leaves. Subsequently, the press-fitting driving member 31 drives the stator inner support 34 to enter the stator to reach the set position. At this time, the stator press-fitting part 33 abuts against the upper end face of the stator. After the stator inner support 34 grabs the stator from the inside of the stator, the press-fitting driving member 31 drives the stator press-fitting part 33 to descend through the press-fitting mounting plate 32, and presses the stator into the cylinder. Since the stator press-fitting part 33 is arranged on the outer circumferential side of the stator inner support 34, the movements of the two will not interfere with each other, and the stator can be pressed quickly and stably.

[0030] As Figure 5 shown in the figure, the end cover transfer mechanism 4 includes a lifting assembly 5, a displacement assembly 6, a rotating assembly 7 and a grasping assembly 8, which are sequentially and orderly connected. The lifting assembly 5 is used to control the vertical lifting of the grasping assembly 8, the displacement assembly 6 is used to control the horizontal movement of the grasping assembly 8, the rotating assembly 7 is used to control the rotation of the end cover by the grasping assembly 8, and the grasping assembly 8 is used to grasp the end cover. The displacement assembly 6, the rotating assembly 7 and the grasping assembly 8 can be driven by the lifting assembly 5 to enter below the stator press-fitting mechanism 3, so as to grab the end cover and leave first, leaving space for the stator press-fitting mechanism 3 to press-fit the stator.

[0031] Furthermore, the lifting assembly 5 includes a lifting driving member 51 and a lifting plate 52. The lifting plate 52 is movably connected to the main frame 1 through a plurality of guide columns 53. The lifting driving member 51 can drive the lifting plate 52 to vertically lift, so as to drive the displacement assembly 6, the rotating assembly 7 and the grasping assembly 8 to lift synchronously.

[0032] The displacement assembly 6 includes a displacement driving member 61, a first driving pulley 62, a first driven pulley 63, a first belt and a displacement plate 64. The first driving pulley 62 is arranged at the output end of the displacement driving member 61. The first driven pulley 63 is arranged on the lifting plate 52. The first belt is sleeved outside the first driving pulley 62 and the first driven pulley 63. The displacement plate 64 is arranged on the first belt through a jacket 65 and is also movably arranged on the lifting plate 52 through a displacement slide rail 66. When the first driving pulley 62 rotates, it drives the first belt to slide in cooperation with the first driven pulley 63. At this time, the displacement plate 64 moves horizontally along with the first belt. At the same time, the displacement slide rail 66 is used to ensure the stable operation of the displacement plate 64.

[0033] The rotating assembly 7 includes a rotating plate 71, a rotating driving member 73, a second driving pulley 74, a second driven pulley 76, a rotating shaft 75 and a second belt. The rotating plate 71 is arranged on the displacement plate 64 through a plurality of first connecting columns 72. The rotating driving member 73 is arranged on the rotating plate 71. The second driving pulley 74 is arranged at the output end of the rotating driving member 73. The rotating shaft 75 is inserted through the rotating plate 71 through a bearing. The second driven pulley 76 is sleeved outside the rotating shaft 75. The belt is sleeved outside the second driving pulley 74 and the second driven pulley 76. When the second driving pulley 74 rotates, it drives the second driven pulley 76 to rotate through the second belt, so as to realize the rotation of the rotating shaft 75.

[0034] The grasping assembly 8 includes a grasping plate 81, a grasping driving member 82 and grasping jaws 84. The grasping plate 81 is arranged at the lower end of the rotating shaft 75 and can rotate along with the rotating shaft 75. The grasping driving member 82 is arranged on the grasping plate 81 through a second connecting column 83. The grasping jaws 84 are arranged at the output end of the grasping driving member 82 and can grasp both ends of the end cover.

[0035] Therefore, through the mutual cooperation of the lifting assembly 5, the displacement assembly 6, the rotating assembly 7 and the grasping assembly 8, the grasping, rotation, horizontal movement and vertical movement of the end cover can be completed. Among them, the rotation and the horizontal movement can be carried out simultaneously. During the movement of the end cover, the stator wiring can be kept in the through hole of the end cover in real time. Through the rotation action, the stretching distance of the wiring is effectively reduced, and the need to reserve too long wiring is avoided.
