Description

Technical Field

[0001] This invention relates to the field of motor manufacturing, and in particular to an automated insertion device for an electromagnetic block in a motor core. Background Technology

[0002] The existing method of inserting electromagnetic blocks into the motor core is a manual operation. The insertion position of the electromagnetic blocks is controlled by an auxiliary fixture. When inserting electromagnetic blocks, the operator must first pick up the auxiliary fixture and place it on the pre-assembly fixture, and then pick up the electromagnetic blocks and insert them into the core one by one. After visual confirmation, the blocks are sent to the CCD inspection process. Because the manual operation is inefficient and has poor productivity, production capacity cannot be improved. The process is too cumbersome and time-consuming, resulting in a waste of manpower. Summary of the Invention

[0026] The technical solution protected by this invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, an automated insertion device for an electromagnetic block of a motor core includes: a conveyor line 1, on which multiple fixtures 2 are arranged for placing the iron core; a first robotic arm 3, a first electromagnetic block loading mechanism 4, a second robotic arm, a second electromagnetic block loading mechanism 7, a CCD detection mechanism 8, and a unloading mechanism 9 are arranged sequentially along the conveyor line 1; wherein the first electromagnetic block loading mechanism 4 and the second electromagnetic block loading mechanism 7 have the same structure; a guide mechanism 5 and a pressing auxiliary mechanism 6 are respectively provided at the first electromagnetic block loading mechanism 4 and the second electromagnetic block loading mechanism 7. A blocking mechanism is provided at each station of the conveyor line 1, that is, a blocking block is fixed to the end of a cylinder piston rod; when the fixture reaches the station, the cylinder drives the blocking block to push out and block the fixture.

[0028] like Figure 2 , Figure 3 As shown, the first electromagnetic block feeding mechanism 4 includes a turntable 41 with two symmetrically arranged material boxes: a first material box 42 and a second material box 43. When one material box is in use, the other material box is used for feeding. A flipping shaft 44 is arranged on the side of the turntable 41 near the conveyor line 1. Multiple grippers 47 are evenly arranged on the flipping shaft 44. A flipping cylinder 46 is arranged on the outside of the flipping shaft 44 for flipping the flipping shaft 44. A pulling mechanism 45 is arranged below the flipping shaft 44. The grippers 47 are used to grab the electromagnetic block 11 from the pulling mechanism. After flipping 90 degrees, the first robot arm 3 grabs it and puts it into the fixture 2 of the conveyor line. Since the fixture 2 contains an iron core, the electromagnetic block is installed.

[0029] The material pulling mechanism 45 includes: a material pulling guide rail 49 and a material pulling slider 48 disposed on the material pulling guide rail 49. The material pulling slider 48 is driven by a lead screw by a servo motor. When the servo motor rotates, the lead screw rotates, and the material pulling slider 48 moves on the material pulling guide rail 49. A material pulling lifting cylinder 410 is disposed on the material pulling slider 48. A material pulling plate 411 is disposed at the end of the piston rod of the material pulling lifting cylinder 410. Driven by the material pulling slider 48 and the material pulling lifting cylinder 410, the material pulling plate 411 moves between the bottom of the material box and the flipping shaft 44 to feed material.

[0030] In this application, the electromagnetic blocks in the material box are stacked, and the bottom electromagnetic block falls into the material pulling plate 411. The material pulling lifting cylinder 410 drives the material pulling plate 411 to descend. Together with the material pulling slider 48, it moves to the position of the gripper 47 of the flipping shaft. The material pulling lifting cylinder 410 drives the material pulling plate 411 to rise. After the sensor senses that there is material at the corresponding position, the gripper 47 grabs the electromagnetic block from the material pulling plate 411. The material pulling plate 411 is reset and the next set of electromagnetic blocks is grabbed.

[0031] like Figure 4 As shown, the guiding mechanism 5 includes a guiding lifting cylinder 51. A guide plate 52 is provided at the end of the piston rod of the guiding lifting cylinder 51. Several guide grooves 53 are formed on the guide plate 52, and the position of the guide plate 52 corresponds to the fixture 2 on the conveyor line 1. When the fixture 2 reaches below the guide plate 5, a blocking mechanism prevents it from moving forward. The first robotic arm 3 grasps the electromagnetic block, passes it through the guide grooves 53 on the guide plate, and inserts the electromagnetic block 11 into the corresponding position of the iron core in the fixture 2, completing the loading of the electromagnetic block.

[0032] like Figure 4 As shown, the pressing auxiliary mechanism 6 is located near the guide mechanism and includes: a vertical pressing cylinder 63, a horizontal pressing cylinder 62, and a pressing plate 61. The horizontal pressing cylinder 62 is located at the end of the piston rod of the vertical pressing cylinder 63, and the pressing plate 61 is located at the end of the piston rod of the horizontal pressing cylinder 62. When the electromagnetic block rotates into the iron core through the guide groove 63, the horizontal pressing cylinder 62 drives the pressing plate 61 to move above the guide mechanism 5, and the vertical pressing cylinder 63 drives the pressing plate 61 to press down, pressing the electromagnetic block tightly.

[0033] like Figure 5 As shown, the unloading mechanism 9 includes: a horizontal unloading module 91, a vertical unloading module 92 disposed at the horizontal unloading module 91 and movable along the horizontal unloading module 91, and an unloading gripper 93 disposed at the lower end of the vertical unloading module 92 and capable of lifting and lowering. When the assembled product comes from the conveyor line 1, the unloading gripper 93 of the unloading mechanism grabs the product for unloading.

[0034] In this invention, the number of electromagnetic block feeding mechanisms is set to two sets, and the structures are identical. The two sets of electromagnetic block feeding mechanisms perform electromagnetic block feeding and assembly respectively, which improves the assembly efficiency.

[0035] The working principle of this invention is as follows:

[0036] The fixture with the iron core installed moves on the conveyor line 1. When it reaches the first robot arm 3, the gripper 47 at the flip shaft 44 picks up a set of electromagnetic blocks from the pull plate 411. The flip cylinder 46 drives the flip shaft 44 to rotate 90 degrees and senses the angle through the sensor. The first robot arm 3 picks up the electromagnetic blocks from the gripper 47 at the flip shaft 44 and puts them into the iron core of the fixture 2. During the placement process, the guide mechanism 5 is used for limiting and guiding. Then, the pressing auxiliary mechanism 6 presses down on the electromagnetic blocks 11 to ensure that the assembly is completed. After the assembly is completed, the fixture 2 drives the iron core to move on the conveyor line 1. It first passes through the CCD detection mechanism 8 for detection. Products that pass the detection are unloaded by the unloading mechanism 9 into the good product box, and products that fail the detection are unloaded into the defective product box.

[0037] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
