Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly equipment, in particular to a novel magnetic steel inserting machine. Background Technique

[0002] Magnetic steel insertion refers to the process of inserting magnetic steel sheets into the motor rotor, and this process is crucial for the performance of the motor. Traditional magnetic steel insertion methods mostly rely on manual operation, but with the development of technology, automatic magnetic steel inserting machines have gradually become the mainstream.

[0003] At present, there are still many problems to be solved in the automatic insertion of magnetic steel. First, during the feeding process of magnetic steel, in order to reduce the mutual interference between magnetic steels, spacers need to be used to separate the stacked magnetic steels. After the magnetic steels are fed, the corresponding spacers slide down under the action of gravity. However, when the magnetic force is large, the spacers may be adsorbed on the magnetic steels after long-term extrusion, affecting the subsequent feeding of magnetic steels; second, during the automatic magnetic steel insertion process, the fed magnetic steels are also prone to problems such as incorrect polar direction or insufficient magnetism, seriously affecting the performance of the motor.

[0004] Therefore, in view of the deficiencies of the existing technology, it is necessary to design a novel magnetic steel inserting machine to solve the above problems.

[0005] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the present utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above content is well-known to those skilled in the art just because these contents are described in the background technology of the present utility model. Content of the Utility Model

[0006] To overcome the above deficiencies in the existing technology, the purpose of the present utility model is to disclose a novel magnetic steel inserting machine, which is used to improve the efficiency and accuracy of rotor magnetic steel insertion and avoid installing magnetic steels with insufficient magnetism or incorrect magnetic pole direction on the rotor.

[0007] The present utility model discloses a novel magnetic steel inserting machine, which includes a processing table. A turntable is arranged on the processing table. Along the circumferential direction of the turntable, a rotor feeding station, a rotor slot gluing unit, and a magnetic steel inserting unit are sequentially arranged. Among them:

[0008] At least one horizontally rotatable rotor placement seat is arranged along the circumferential direction on the turntable, which is used to place the rotor and rotate the rotor so that the magnetic steel installation area of the rotor can be aligned with the output ends of the rotor slot gluing unit and the magnetic steel inserting unit.

[0009] The magnetic steel insertion unit is provided with a processing frame above the turntable, and a magnetic steel guide slide structure is provided on the processing frame in the vertical direction. The output port of the magnetic steel guide slide structure can be docked with the rotor on the rotor mounting seat, and is used to guide it during the magnetic steel insertion process. A feed port is provided on one side of the magnetic steel guide slide structure, which is used to transport magnetic steel into it. A push rod is slidably connected inside the magnetic steel guide slide structure, and a lifting drive is connected to the rear end of the push rod, which is used to push the magnetic steel into the rotor along the magnetic steel guide slide. A spacer slot is provided on the side of the push rod close to the feed port, and the spacer slot can be docked with the feed port, and is used to drive the spacer to move upward in the vertical direction, thereby separating and removing the spacer from the magnetic steel;

[0010] The processing frame is also equipped with a Y-axis moving mechanism that reciprocates along the horizontal Y-axis. A magnetic steel support mechanism is installed at the output end of the Y-axis moving mechanism. This magnetic steel support mechanism has two parallel magnetic steel guide grooves along the horizontal X-axis. The output ends of these two magnetic steel guide grooves can be docked with the feed port. Each magnetic steel guide groove is equipped with a pusher mechanism that reciprocates along its orientation. The Y-axis moving mechanism allows the desired magnetic steel guide groove to be docked with the feed port, allowing the pusher mechanism to quickly push the corresponding magnetic steel into the magnetic steel guide slide structure.

[0011] Preferred technical solution: A Hall switch for detecting the polarity direction of the magnet is provided on the magnet guide slide structure. The Hall switch is arranged below the feed port. The Hall switch detects the polarity and magnetic strength of the magnet. When a magnet that does not meet the requirements passes by, the signal feedback from the Hall switch can be used to give a timely warning to prevent abnormal magnets from being inserted into the rotor.

[0012] A preferred technical solution: The magnetic guide slide structure is further equipped with at least one catalyst spraying device, located below the Hall effect switch. The catalyst spraying device's output is connected to the side of the magnetic guide slide structure's conveying channel. Spraying the catalyst on the magnetic surface accelerates the bonding of the magnetic and glue.

[0013] Preferred technical solution: A horizontal rotation drive is provided below the turntable at a position corresponding to the magnetic guide slide structure. The output end of the horizontal rotation drive can be connected to the rotor mounting seat for transmission, so that the rotor on it can be quickly aligned with the output end of the rotor slot gluing unit or the magnetic steel insertion unit.

[0014] Preferred technical solution: The pushing mechanism includes a screw rod arranged along the horizontal X-axis direction, and a push plate structure is connected to the screw rod for transmission. The output end of the push plate structure is arranged at the magnetic steel guide groove. The screw rod is driven by a stepper motor. The stepper motor drive can improve the accuracy of the conveying distance of the magnetic steel in the magnetic steel guide groove.

[0015] Preferred technical solution: An elastic buffer pressure head is provided at the output end of the pusher plate structure to prevent the cumulative deviation of the thickness of the magnetic steel and the spacer from affecting the accuracy of the magnetic steel conveying distance.

[0016] Preferred technical solution: A limit plate is provided above the output end of the magnetic steel guide groove to prevent the pusher from driving the magnetic steel or spacer in the magnetic steel guide groove to move upward during movement.

[0017] Preferred technical solution: Both the magnetic steel guide slideway structure and the pusher are made of non-magnetic materials to avoid interfering with the positioning and installation of the magnetic steel.

[0018] Due to the application of the above technical solutions, the beneficial effects of a new type of magnetic steel inserting machine of the present utility model are as follows:

[0019] (1) By providing a spacer card slot on the pusher, when the pusher moves downward, it can push the magnetic steel downward and insert it into the rotor. When the pusher moves upward, it can drive the spacer to move upward and separate from the magnetic steel through the spacer card slot. The designed structure is simple and the effect is remarkable;

[0020] (2) A stepping motor is used in cooperation with an elastic buffer pressure head to convey the stacked magnetic steel and spacer, avoiding the deviation of the conveying distance caused by the cumulative dimensional errors of the magnetic steel and the spacer;

[0021] (3) Two magnetic steel guide grooves are used to convey the low magnetic steel. Different polarities or specifications of magnetic steel can be loaded in the two magnetic steel guide grooves, improving the flexibility and production efficiency of the magnetic steel inserting machine;

[0022] (4) A Hall switch is provided below the feed inlet to timely detect abnormal magnetic steel sheets, avoid abnormal magnetic steel sheets from entering the rotor, and thus ensure the installation quality and performance of the motor. Description of the drawings
