Description

Technical Field

[0001] This utility model relates to the field of stator and rotor manufacturing technology, specifically to a mechanical hand for handling stator and rotor laminations for motors. Background Technology

[0002] Stator and rotor laminations are important components of electric motors. They are generally formed from silicon steel sheets through stamping. Existing dies for processing stator and rotor laminations typically include an upper die base, a lower die base, an ejector mechanism, and a punch and a die fixed on the upper and lower die bases, respectively. The die has a forming cavity. In use, the lamination to be pressed is placed in the forming cavity, and the punch moves downward to impact the lamination, shaping it according to the shape of the cavity. After stamping, the ejector mechanism ejects the lamination from the forming cavity.

[0003] After the existing stator and rotor laminations are stamped, they need to be manually removed from the mold, which is inefficient, time-consuming and labor-intensive, and poses safety hazards. Therefore, there is an urgent need for a stator and rotor lamination material handling robot. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example

[0026] Combination Figure 1-5 As shown, this embodiment provides a robotic arm for picking up motor stator and rotor laminations, including: a main body mechanism 100 and a ranging mechanism 200.

[0027] The main structure 100 includes a central seat 110, a support arm 120 integrally fixed to the outside of the central seat 110 in a ring array, a transmission component 130 rotatably installed in the inner cavity of the support and extending into the central seat 110, a drive component 140 installed at the top of the central seat 110 and extending into the central seat 110 to mesh with the transmission component 130, a movable seat 150 movably disposed in the inner cavity of the support arm 120 and extending out of the support arm 120, an electromagnet 160 installed at the bottom of the movable seat 150, a top seat 170 disposed above the central seat 110, and an electric telescopic rod 180 fixed on the top seat 170 and whose bottom end is fixedly connected to the central seat 110.

[0028] The center seat 110 is used to install other components. The support arm 120 is integrally fixed on the center seat 110. A groove 121 is opened at the bottom end of the support arm 120. The transmission component 130 includes a threaded rod 131 rotatably mounted on the inner wall of the groove 121 and with its end extending into the center seat 110, and a first bevel gear 132 fixed on the end of the threaded rod 131. Meanwhile, the drive component 140 includes a motor 141 mounted on the top of the center seat 110 and with its shaft extending into the inner cavity of the center seat 110, and a second bevel gear 142 fixed on the shaft of the motor 141. The second bevel gear 142 meshes with the first bevel gear 132, so that when the motor 141 starts, it drives the second bevel gear 142 to rotate. The rotation of the second bevel gear 142 drives the first bevel gear 132 to rotate. The rotation of the first bevel gear 132 drives the threaded rod 131 to rotate. The rotation of the threaded rod 131 drives the movable seat 150 to move.

[0029] The movable base 150 is used to install the electromagnet 160 and drive the electromagnet 160 to move and adjust its position, so as to facilitate the adsorption of stator and rotor laminations of different sizes. The movable base 150 includes a threaded sleeve 151 fitted in the groove 121 and a base 152 fixed to the bottom end of the threaded sleeve 151. The threaded rod 131 passes through the threaded sleeve 151 and meshes with the threaded sleeve 151. That is, when the threaded rod 131 rotates, it drives the threaded sleeve 151 to move. The movement of the threaded sleeve 151 drives the base 152 to move, which in turn drives the electromagnet 160 mounted on the base 152 to move, thereby realizing the position adjustment of the electromagnet 160. The electromagnet 160 can attract the stator and rotor, thus facilitating the removal of the stator and rotor laminations from the mold.

[0030] The top seat 170 has ear plates on both sides for connecting to the moving device. A frame 112 is fixed at the top of the center seat 110. The bottom end of the electric telescopic rod 180 is fixedly connected to the top of the frame 112, so that when the electric telescopic rod 180 moves up and down, it can drive the center seat 110 and the support arm 120 to move synchronously. In addition, the top of the center seat 110 has columns 111 arranged in a ring array. The columns 111 move through the top seat 170 to ensure the stability of the center seat 110 when it moves up and down.

[0031] The ranging mechanism 200 is used to monitor the moving distance of the electromagnet 160 in real time to ensure that the electromagnet 160 moves accurately to the designated position. It includes a U-shaped frame 210 slidably mounted on one side support arm 120, a laser ranging sensor transmitter 220 mounted on the top of the U-shaped frame 210, and a laser ranging sensor receiver 230 mounted on one side of the center seat 110. The bottom end of the U-shaped frame 210 on the side support arm 120 is fixedly connected to both sides of the movable seat 150 on the side support arm 120, so that the U-shaped frame 210 can be moved synchronously when the movable seat 150 moves.

[0032] In addition, a sliding groove 122 is symmetrically opened at the top of one side support arm 120, and a sliding strip 211 is symmetrically arranged on the inner side of the U-shaped frame 210. The sliding strip 211 slides and fits into the sliding groove 122 to ensure the stability of the U-shaped frame 210 when it moves.

[0033] The laser rangefinder transmitter 220 and the laser rangefinder receiver 230 work together to monitor the moving distance of the U-shaped frame 210 in real time, that is, to monitor the moving distance of the electromagnet 160 in real time.

[0034] The working principle and usage process of this utility model are as follows: In use, the moving device is fixedly connected to the top seat 170. After the stator and rotor laminations are stamped, the moving device moves the top seat 170 above the stator and rotor laminations. At this time, the electric telescopic rod 180 extends, causing the center seat 110 and support arm 120 to move downwards, making the electromagnet 160 adhere tightly to the stator and rotor laminations. Then, the electromagnet 160 is energized, generating magnetic force to attract the stator and rotor laminations. The electric telescopic rod 180 moves the center seat 110 and support arm 120 upwards, causing the stator and rotor laminations to be removed from the mold. Simultaneously, the moving mechanism moves the top seat 170 above the material rack, the electromagnet 160 is de-energized, releasing the attraction to the stator and rotor laminations, and the stator and rotor laminations fall into the material rack. Furthermore, when it is necessary to stamp stator and rotor laminations of different sizes... When the laminations are adsorbed, the motor 141 is started, which drives the second bevel gear 142 to rotate. The rotation of the second bevel gear 142 drives the first bevel gear 132 to rotate. The rotation of the first bevel gear 132 drives the threaded rod 131 to rotate. The rotation of the threaded rod 131 drives the threaded sleeve 151 to move. The movement of the threaded sleeve 151 drives the base 152 to move, which in turn drives the electromagnet 160 to move. Adjusting the position relative to the electromagnet 160 facilitates the adsorption of stator and rotor laminations of different sizes. In addition, when the base 152 moves, it drives the U-shaped frame 210 to move. At this time, the laser range sensor transmitter 220 and the laser range sensor receiver 230 can monitor the moving distance of the U-shaped frame 210 in real time to ensure that the electromagnet 160 can move accurately to the designated position.
