Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, specifically a stator insulation paper assembly device. Background Technology

[0002] Depending on the center height, motors come in various specifications. Each specification is further divided into 2-pole, 4-pole, 6-pole, and 8-pole products based on the number of poles. The stator slots of different specifications and pole numbers are all different. The stator slots are located on the stator core of the motor and are used to embed the excitation winding. To prevent electrical conductivity between the excitation winding and the stator core, insulating paper needs to be inserted into the stator slots, which usually requires a motor stator insulating paper insertion machine.

[0003] However, existing motor stator insulation paper insertion machines have a single structural form for inserting insulation paper tape into the stator slots, making it difficult to fix and pull the insulation paper tape, and unable to insert it accurately into each corresponding stator slot simultaneously, resulting in low work efficiency. Therefore, a stator insulation paper assembly device is proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a stator insulation paper assembly device in order to solve the above-mentioned problems.

[0005] The present invention achieves the above-mentioned objective through the following technical solution: a stator insulating paper assembly device, comprising a strip-shaped insert for inserting insulating paper into the stator structure slot and insulating paper shaping perforations matching the cross-sectional shape of the insulating paper slot, a group of the insulating paper shaping perforations being arranged in a ring on a ring block, and the inner edge of one end of the opening of each insulating paper shaping perforation being fixedly connected to one end face of the strip-shaped insert, electrode blades being distributed at intervals between the strip-shaped inserts having the same number as the group of insulating paper shaping perforations, and a pulling plate extending into the interior of each strip-shaped insert, and strip-shaped holes and cutting grooves being respectively opened in the horizontal and vertical directions on the top surface of the strip-shaped insert; The electrode blades cut through the corresponding cutting grooves by side rotation, and a group of electrode blades are arranged in a ring inside one end of a large-diameter short tube. The other end of the large-diameter short tube is rotatably connected to one end of the ring block through a bearing. Two short cylinders are installed alternately inside a rectangular hole located on one side wall of the traction plate. Each short cylinder has a pneumatic suction cup installed at its output end, and the pneumatic suction cup extends through the short cylinder and passes through the strip hole. The other end of the traction plate is arranged in a ring on the annular surface of the circular frame, and a long cylinder is installed in the middle of the back of the circular frame.

[0006] Preferably, the surface of the large-diameter short pipe is provided with arc-shaped holes, and the other end of the large-diameter short pipe is equipped with a toothed ring, which is meshed with a gear, and the shaft end of the gear in the middle is connected to the motor through a coupling.

[0007] Preferably, the motor is mounted on the side plate, and one end of the side plate is fixedly mounted on one side of the annular surface of the ring block, while a robotic arm connecting flange is fixedly mounted on the other side of the annular surface of the ring block.

[0008] Preferably, the cylinder end of the long cylinder is fixedly connected to the middle of the three-leaf frame located inside the ring block.

[0009] Preferably, a pneumatic controller is installed inside the circular frame, and the inside of the circular frame is connected to the inside of a rectangular hole located on the traction plate through a channel.

[0010] Preferably, the distance between the cutting groove and one end of the strip insert depends on the length of the corresponding stator structure.

[0011] Preferably, the distance between the cutting groove and the other end of the strip insert is greater than the length of the pull plate.

[0012] Preferably, the pneumatic suction cup is adsorbed and contacted with the inner surface of the insulating paper tape located at the strip hole.

[0013] The beneficial effects of this invention are as follows: By shaping and perforating the insulating paper to match the cross-sectional shape of the slot for inserting the insulating paper into the stator structure, and combining this with a strip-shaped insert for inserting the insulating paper into the slot, the high degree of matching of the insulating paper into the slot is improved. At the same time, the pneumatic suction cup located inside the strip-shaped insert is used to adsorb and fix the inner side of the insulating paper through the strip hole via a short cylinder, and the long cylinder pushes the connected pneumatic suction cup forward. This not only solves the problem of inconvenient fixing of the insulating paper, but also ensures the accuracy of the ring-shaped insulating paper inserts that are adsorbed and fixed inside the slot, and the work efficiency is high, resulting in an overall increase in processing and manufacturing output.

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] Please see Figure 1-7As shown, a stator insulation paper assembly device includes a strip-shaped insert 1 for inserting insulation paper into the stator structure slot and insulation paper shaping perforations 210 that match the cross-sectional shape of the insulation paper slot. A group of the insulation paper shaping perforations 210 are arranged in a ring on a ring block 2, and the inner edge of one end of each insulation paper shaping perforation 210 is fixedly connected to one end face of the strip-shaped insert 1. Electrode blades 310 are distributed at intervals between the strip-shaped inserts 1, which are the same number as the group of insulation paper shaping perforations 210. One end of a pulling plate 14 extends into the interior of each strip-shaped insert 1, and strip-shaped holes 110 and cutting grooves 120 are respectively opened in the horizontal and vertical directions on the top surface of the strip-shaped insert 1. The electrode blade 310 cuts through the corresponding cutting groove 120 by side rotation, and a group of electrode blades 310 are arranged in a ring and installed inside one end port of the large-diameter short tube 3. The other end port of the large-diameter short tube 3 is rotatably connected to one end of the ring block 2 through the bearing 10. Two short cylinders 15 are installed alternately inside the rectangular hole 1410 located on one side wall of the pulling plate 14. Each short cylinder 15 has a pneumatic suction cup 13 installed at its output end, and the pneumatic suction cup 13 extends through the strip hole 110 through the short cylinder 15. The other end of the group of pulling plates 14 is arranged in a ring and installed on the annular surface of the circular frame 11, and a long cylinder 4 is installed in the middle of the back of the circular frame 11.

[0021] Combination Figure 1 and Figure 7 As shown, the surface of the large-diameter short tube 3 is provided with arc-shaped holes 320, and the other end of the large-diameter short tube 3 is equipped with a toothed ring 5. The toothed ring 5 is meshed with a gear 6, and the shaft end of the middle part of the gear 6 is connected to the motor 7 through a coupling. The motor 7 drives the large-diameter short tube 3 connected by the gear 6 and the toothed ring 5 to rotate, so that the electrode blades 310, which are arranged in a ring at one end of the large-diameter short tube 3, rotate and cut through the corresponding cutting groove 120, thereby realizing the function of cutting the insulating paper tape 16. This solves the problem of asynchronous and inconvenient cutting of the ring-shaped insulating paper.

[0022] like Figure 1 As shown, the motor 7 is mounted on the side plate 8, and one end of the side plate 8 is fixedly mounted on a point on the annular surface of the ring block 2. A robotic arm connecting flange 9 is fixedly mounted on the other point on the annular surface of the ring block 2. Through the robotic arm connecting flange 9, the entire device can be connected to an external robotic arm to achieve the effect of displacement adjustment.

[0023] Furthermore, the cylinder end of the long cylinder 4 is fixedly connected to the middle of the three-leaf frame located inside the ring block 2.

[0024] A pneumatic controller 12 is installed inside the circular frame 11, and the inside of the circular frame 11 is connected to the inside of the rectangular hole 1410 on the traction plate 14 through a channel. The pneumatic controller 12 is used to implement pneumatic operation control of the long cylinder 4, the short cylinder 15 and the pneumatic suction cup 13 respectively, so as to meet the needs of various actions.

[0025] Furthermore, the distance between the cutting groove 120 and one end of the strip insert 1 depends on the length of the corresponding stator structure, and the distance between the cutting groove 120 and the other end of the strip insert 1 is greater than the length of the traction plate 14.

[0026] Furthermore, the pneumatic suction cup 13 is adsorbed and contacted with the inner surface of the insulating paper tape 16 located at the strip hole 110.

[0027] Working principle: One end of each insulating paper strip 16 in a group is passed through the corresponding insulating paper shaping perforation 210. Simultaneously, a pneumatic suction cup 13 moves upward, passing through the strip hole 110 to adhere to the inner side of the insulating paper strip 16. Using a robotic arm connecting flange 9 connected to an external robotic arm, the entire assembly is brought closer to the stator structure until all the strip inserts 1 are inserted into their corresponding insulating paper placement slots in the stator structure. At this point, the long cylinder 4 extends, driving the pneumatic suction cup 13, connected via the circular frame 11, the pulling plate 14, and the short cylinder 15, to move towards one end of the strip insert 1, achieving the desired effect. The effect of the movable and fixed insulating paper strip 16 moving and passing through the corresponding insulating paper placement stator structure slot is achieved. After the operation is completed, the running motor 7 drives the gear 6 and the gear ring 5 located on the large diameter short tube 3 to rotate, so that the rotating large diameter short tube 3 drives the connected electrode blade 310 to rotate to the side and quickly cut the corresponding part of the insulating paper strip 16 located at the through-cutting groove 120, so that the cut part of the insulating paper strip 16 is placed inside the insulating paper placement stator structure slot. After the above process of assembling the insulating paper strip 16 on the stator structure is completed, all the execution structures are reset. In summary: By using the insulating paper shaping perforation 210 that matches the cross-sectional shape of the insulating paper placement stator structure slot, and combining it with the strip-shaped insert 1 for inserting the insulating paper into the insulating paper placement stator structure slot, the high matching accuracy of guiding the insulating paper into the insulating paper placement stator structure slot is improved. At the same time, the pneumatic suction cup 13 located inside the strip-shaped insert 1 is used to adsorb and fix the inner side of the insulating paper through the strip-shaped hole 110 via the short cylinder 15, and the long cylinder 4 pushes the connected pneumatic suction cup 13 forward. This not only solves the problem of inconvenient fixing of the insulating paper, but also ensures the accuracy of the ring-shaped insulating paper being adsorbed and fixed in the insulating paper placement stator structure slot, and the work efficiency is high, resulting in an overall increase in processing and manufacturing output.
