Description

Technical Field

[0001] This technical solution relates to the field of motor technology, specifically to a stator core weight correction and positioning device. Background Technology

[0002] During the processing of motor stator cores, silicon steel sheets need to be stacked together, and then the sheets are pressed onto the side walls of the stator core using a sheet-fastening machine. For example, a stator core sheet-fastening assembly device disclosed in Chinese Patent CN202011371699.4 requires manual placement of a pre-ordered quantity of silicon steel sheets onto the guide posts of the sheet-fastening machine, then placing the sheets into the grooves on the outer ring of the stator core, and finally pressing the sheets into place using the sheet-fastening machine.

[0003] However, existing chip fastening machines still have some shortcomings: in order to ensure that the produced stators meet the design requirements, they generally need to be weighed before chip fastening. After the silicon steel sheets are stacked, they are usually weighed and the weight is adjusted to meet the set value manually, which results in low production efficiency and high production costs. Furthermore, manual weighing and replenishment can easily lead to inaccurate production quality and reduce the yield of high-quality products. Summary of the Invention

[0004] The purpose of this technical solution is to provide a stator core weight correction and positioning device. The device feeds the stator core through a stator feeding device, weighs it through a weighing device, screens out overweight stator cores through a screening device, positions it through a rotary positioning device, and increases the weight to the set weight through a replenishing device. This improves the problem of low production efficiency caused by manual weighing, screening, and replenishing.

[0090] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-8 .

[0091] A stator core weight correction and positioning device includes: a frame 1 with a worktable 11 mounted thereon; a stator feeding device 2 mounted on the worktable 11 for feeding stator cores 100 and moving them to a set position on the worktable 11; a weighing device 10, such as a platform scale or electronic scale (existing technology), mounted on the frame 1 for weighing the stator cores 100 moved by the stator feeding device 2, ensuring that the weight of the stator cores 100 meets the set weight before the corresponding clamping operation 101 is performed; and a screening device 3 mounted on the worktable 11 for screening out stator cores 100 exceeding the set weight. When an overweight stator core 100 is weighed by the weighing device 10, it is then... When the screening device 3 is moved out of the stator feeding device 2, it will no longer be transported or moved by the stator feeding device 2. The rotary positioning device 4, which is installed on the workbench 11, is used to rotate the stator core 100 moved from the stator feeding device 2 to a set angle, thereby ensuring the accurate positioning of the subsequent fastening piece 101 and ensuring the accurate position and angle of the feeding device 5 placing the silicon steel sheet 103 on the stator core 100. The feeding device 5, which is installed on the workbench 11, is used to increase the weight of the stator core 100 in the rotary positioning device 4 to a set weight. After being weighed by the weighing device 10, the system software calculates how many silicon steel sheets 103 are missing, and then the feeding device 5 performs the corresponding number of feedings, with one silicon steel sheet 103 being added at a time, and multiple feedings are performed.

[0092] The stator feeding device 2 includes: a conveyor belt mechanism 21, which is prior art, mounted on the frame 1, used to move the stator core 100 to the workbench 11. One end of the conveyor belt mechanism 21 is connected to the workbench 11, and the other end is connected to the previous stacking station, used to feed the stator core 100 formed by stacking silicon steel sheets 103; and a pushing mechanism 22, mounted on the workbench 11. The pushing mechanism 22 has a fork 228 for pushing the stator core 100 into the weighing device 10, and a fork 229 for pushing the stator core 100 into the weighing device 10. The material is moved to the rotary positioning device 4; the second pushing mechanism 23 is installed on the workbench 11 and is used to move the stator core 100 from the weighing device 10 to the screening device 3; when the conveyor belt mechanism 21 moves the stator core 100 to the front end of the fork 228 of the first pushing mechanism 22, the fork 228 pushes the stator core 100 into the weighing device 10, and then the second pushing mechanism 23 pushes the stator core 100 into the screen device 3 (i.e., the transfer area 12 of the workbench 11), and the fork 229 pushes the stator core 100 that is not overweight into the rotary positioning device 4.

[0093] The pusher mechanism 22 can be driven by two power sources or by the same power source. In this design, the pusher mechanism 22 includes: a slide rail 221 mounted on the worktable 11, with a slider 222 slidably mounted on the slide rail 221; and a push plate 223 mounted on the slider 222, with a pusher fork 228 and a pusher fork 229 mounted on the push plate 223. The front end of the pusher fork 228 has a limiting groove 224, and the front end of the pusher fork 229 has a limiting groove 225. The side wall of the limiting groove 224 away from the discharge end of the conveyor belt mechanism 21 has a limiting part 226, which prevents the stator core 100 conveyed by the conveyor belt mechanism 21 from falling off the limit. The stator core 100 is moved out of the slot 224 to ensure the accuracy of the feeding position. The drive component 227, which is a cylinder, linear motor or push rod, is installed on the worktable 11 and the drive end of the drive component 227 is movably connected to the push plate 223. When the stator core 100 moves from the conveyor belt mechanism 21 into the limiting slot 224 and movably abuts against the limiting part 226, the drive component 227 drives the push plate 223 to move, so that the stator core 100 moves to the weighing device 10. The pusher mechanism 23 moves the stator core 100 from the weighing device 10 to the transfer area 12 on the worktable 11. Then, the limiting slot 225 of the push plate 223 pushes the stator core 100 in the transfer area 12 to the rotary positioning device 4.

[0094] The second pushing mechanism 23 includes: a slide rail 231, which is mounted on the worktable 11, and a slider 232 is slidably arranged on the slide rail 231; a push plate 233, which is mounted on the slider 232, and a limiting groove 3 234 is provided on the push plate 233; a driving component 235, which is a cylinder, a linear motor or a push rod, is mounted on the worktable 11, and the driving end of the driving component 235 is movably connected to the push plate 233; the driving component 235 pushes the push plate 233 to move, so that the stator core 100 is placed in the limiting groove 3 234, and the stator core 100 is moved from the weighing device 10 to the transfer area 12 of the worktable 11; the limiting groove 1 224, the limiting groove 225 and the limiting groove 3 234 are all adapted to the side wall shape of the stator core 100 and are arc-shaped.

[0095] The workbench 11 is provided with an elongated hole 13; the screening device 3 includes: a slide rail 31, which is installed at the lower end of the workbench 11, and a slider 32 is slidably mounted on the slide rail 31; a drive component 33, which is a cylinder, an electric push rod, or a linear motor, which is installed at the lower end of the workbench 11, and the drive end of the drive component 33 is movably connected to the slider 32; and a drive component 4 34, which is a cylinder, an electric push rod, or a linear motor, which is installed on the slider 32, and a push rod 35 is installed on the drive end of the drive component 4 34, the upper end of the push rod 35 being movably inserted into the elongated hole 13 on the workbench 11. It can extend out of the upper end of the worktable 11; when the upper end of the push rod 35 extends out of the upper end of the worktable 11, the driving component 33 drives the slider 32 to move, thereby driving the push rod 35 to move in the elongated hole 13, so that the push rod 35 pushes the stator core 100 out of the transfer area 12 of the worktable 11, thereby removing the overweight stator core 100 and preventing the shift fork component 229 from pushing the overweight stator core 100 into the rotary positioning device 4. When screening is not required, the upper end of the push rod 35 does not extend out of the upper end of the worktable 11, that is, it retracts into the elongated hole 13.

[0096] The slider 32 is provided with a mounting plate 36, which is movably connected to the drive end of the drive component 33. The drive component 4 34 is installed on the mounting plate 36, and the push rod 35 slides through the mounting plate 36, ensuring the stability of the push rod 35 when it moves up and down.

[0097] The rotary positioning device 4 includes: a rotation mechanism 41, which is mounted on the worktable 11 and used to rotate the stator core 100 to a set angle, thereby ensuring that the groove 102 on the side wall of the stator core 100 is facing correctly and that the locking tab 101 can be accurately pressed into the groove 102; a pressing mechanism 42, which is mounted on the worktable 11 and located above the rotation mechanism 41, and used to press the stator core 100 onto the rotation mechanism 41, ensuring that the silicon steel sheets 103 of the upper and lower parts of the stacked stator core 100 can rotate synchronously; and a sensing mechanism. 43, which is installed on the workbench 11, is used to sense the rotation angle of the stator core 100 and ensure that the groove 102 is facing correctly; the rotation mechanism 41 includes: a driving component 411, which is a motor or a rotary cylinder, which is installed at the lower end of the workbench 11; a rotating seat 412, which is rotatably disposed inside the workbench 11, and the upper end surface of the rotating seat 412 does not protrude from the upper end surface of the workbench 11, and the rotating seat 412 is installed on the driving end of the driving component 411; the stator core 100 moves from the upper end surface of the workbench 11 to the upper end of the rotating seat 412 under the push of the pushing mechanism 22.

[0098] The pressing mechanism 42 includes: a slide rail 421, which is vertically mounted on the support frame 14 at the upper end of the worktable 11, and a slider 422 is slidably mounted on the slide rail 421; a pressing frame 423, which is mounted on the slider 422; a pressing die 424, which is rotatably mounted at the lower end of the pressing frame 423, for pressing the stator core 100 onto the rotating mechanism 41; and a driving component 425, which is a linear motor, an electric push rod, or a cylinder, mounted on the support frame 14, and the driving end of the driving component 425 is movably connected to the pressing frame 423 for driving the pressing frame 423. The mold moves downward, causing the first mold 424 to press against the upper end of the stator core 100. The first mold 424 has an insertion part 4241 and a pressing part 4242. The insertion part 4241 is used to insert into the stator core 100 and move against the inner wall of the stator core 100. The pressing part 4242 is used to move against the upper end of the stator core 100. The lower edge of the insertion part 4241 has a guide surface 4243 for guiding the insertion part 4241 into the stator core 100. The first mold 424 and the lower pressure frame 423 are rotatably connected by bearings or annular groove protrusions.

[0099] The sensing mechanism 43 includes: a moving component 431, which is mounted on the worktable 11; a sensor 432, which is mounted on the moving component 431; and a sensing element, which is mounted on the sensor 432. When the moving component 431 drives the sensing element to move and abut against the side wall of the stator core 100 and is not placed in the groove 102, the sensing element and the sensor 432 are in a first trigger state. At this time, the rotation mechanism 41 needs to work to rotate the stator core 100. When the rotation mechanism 41 drives the stator core 100 to rotate, so that the end of the sensing element is placed in the groove 102 on the side wall of the stator core 100, the sensing element and the sensor 432 are in a second trigger state. At this time, the rotation mechanism 41 stops working.

[0100] The specific structure of the sensing element is as follows: a spring plate 433, the rear end of which is movably connected to the sensor 432, and the front half of the spring plate 433 movably abuts against the sensing part 4321 of the sensor 432; a roller 434, which is rotatably disposed at the front end of the spring plate 433; when the moving component 431 drives the roller 434 to movably abut against the side wall of the stator core 100, the front half of the spring plate 433 undergoes elastic deformation and abuts against the sensing part 4321 of the sensor 432, and the sensing element and the sensor 432 are in the first trigger state. At this time, the rotating mechanism 41 performs rotation operation. When the rotating mechanism 41 drives the stator core 100 to rotate, the elastic deformation of the spring plate 433 causes the roller 434 to movably place in the groove 102 of the side wall of the stator core 100, the front half of the spring plate 433 and the sensing part 4321 separate, and the sensing element and the sensor 432 are in the second trigger state, and the rotating mechanism 41 stops working.

[0101] Alternatively, the specific structure of the sensing element is as follows: a fixed base 435, which is mounted on the movable component 431, and a sliding groove 4351 is provided inside the fixed base 435; the sensor 432 is mounted on the fixed base 435 or the movable component 431; a sliding member 436, which is slidably disposed in the sliding groove 4351, and the front end of the sliding member 436 extends movably beyond the front end of the fixed base 435; the rear end of the sliding member 436 has a sensing part 4361, which is in sensing contact with the sensor 432; an elastic member, which is a tension spring or rubber band, one end of which is movably connected to the sliding member 436, and the other end is movably connected to the fixed base 435, for giving the front end of the sliding member 436 a tendency to extend beyond the front end of the fixed base 435; when the movable component 431 drives the fixed base 435 closer to the stator... When the stator core 100 is in operation, the front end of the sliding member 436 moves against the side wall of the stator core 100 and overcomes the force of the elastic member, causing the front end of the sliding member 436 to retract into the sliding groove 4351. This causes the second sensing part 4361 to separate from the first sensing part 4321 of the sensor 432. The sensing member and the sensor 432 are in the first triggered state, and the first rotating mechanism 41 is in the working state. When the first rotating mechanism 41 drives the stator core 100 to rotate, the elastic member causes the front end of the sliding member 436 to extend out of the front end of the fixed seat 435 and be placed in the groove 102 of the side wall of the stator core 100. This causes the first sensing part 4321 and the second sensing part 4361 to make contact. The sensing member and the sensor 432 are in the second triggered state, and the first rotating mechanism 41 stops working.

[0102] The moving component 431 includes: a slide rail 4311, which is mounted on the worktable 11, and a slider 4312 is slidably disposed on the slide rail 4311, the slider 4312 being movably connected to the sensor 432 or the fixed base 435; and a driving component 4313, which is a cylinder, a linear motor or an electric push rod, mounted on the worktable 11, and the driving end of the driving component 4313 being movably connected to the slider 4312, for driving the sensor 432 and the sensing element to approach the side wall of the stator core 100 located in the rotating mechanism 41.

Each silicon steel sheet 103 has the same weight and size, but the silicon steel sheets 103 stored in hopper 51 are flat and do not have grooves or positioning protrusions on their surface. However, the stator core 100 in the rotary positioning device 4 consists of several silicon steel sheets 103 with grooves and positioning protrusions stacked together, and the uppermost silicon steel sheet 103 has a groove on its upper end surface. Adjacent silicon steel sheets 103 are positioned by the grooves and positioning protrusions, while preventing the stator core 100 from falling apart when moving. The feeding mechanism 52 includes: a slide rail.

The drive component 8 58 is an electric push rod, linear motor or cylinder, which is mounted on the mounting bracket 1 55, and the drive end of the drive component 8 58 is movably connected to the slider 7 561. The hopper 1 51 is provided with several positioning posts 511, which are used to insert into the coil groove 104 inside the silicon steel sheet 103 to position the silicon steel sheet 103 and ensure that the side wall groove 102 of the silicon steel sheet 103 in the hopper 1 51 corresponds and matches the angle position of the side wall groove 102 of the stator core 100 in the rotating mechanism 1 41.
