Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the attached Figures 1-10 The technical solutions in the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The present invention provides a technical solution: a precise feeding mechanism for a fully automatic insulating paper inserting machine, which is characterized in that it includes a first feeding mechanism 1. The first feeding mechanism 1 includes a first support frame 1-1. A transverse sliding rod 1-2 is slidably connected to the first support frame 1-1. A longitudinal sliding rod 1-3 is slidably connected to the transverse sliding rod 1-2. A first suction cup structure 1-4 is slidably connected to the longitudinal sliding rod 1-3. A material placing box 1-5 is arranged below the first suction cup structure 1-4; a material transfer mechanism 2. The material transfer mechanism 2 receives the materials transferred from the first feeding mechanism 1. It includes a connecting rod 2-1. A sliding table 2-2 is slidably connected to the connecting rod 2-1. A socket rod 2-3 is fixed on the upper surface of the sliding table 2-2. A first cylinder 2-4 is also fixed thereon. A return plate 2-5 is fixed at the end of the first screw rod shaft of the first cylinder 2-4;The second feeding mechanism 3 receives the materials transmitted from the material transfer mechanism 2. It includes a base 3-1, on which a support frame 3-2 is fixed. On the upper surface of the support frame 3-2, a transverse rod 3-3 is fixed. A manipulator structure 3-4 and a second suction cup structure 3-5 are slidably connected to the front side of the transverse rod 3-3. The manipulator structure 3-4 and the second suction cup structure 3-5 are fixedly connected by a fixing rod 3-6. During operation, the preparatory work is to place the stator bases that need to insert insulating paper in the feeding box 1-5 in a certain order. There are enough stator bases in the feeding box 1-5. Then, the electric control box is started, and the operation of the entire feeding mechanism is controlled through the electric control box. First, the transverse slide bar 1-2 and the longitudinal slide bar 1-3 slide to directly above the stator base to be taken. Then, the first suction cup structure 1-4 slides down along the longitudinal slide bar 1-3 until the first suction cup structure 1-4 sucks the stator base directly below it. Then, the first suction cup structure 1-4 rises along the longitudinal slide bar 1-3 and returns to its original position. Then, the transverse slide bar 1-2 slides to the left, sending the suction cup structure 1-4 directly above the socket rod 2-3 of the material transfer mechanism 2. At this time, the suction cup structure 1-4 will slide down along the longitudinal slide bar 1-3 until it slides to a position very close to the bottom of the socket rod 2-3. Then, the suction cup structure 1-4 will release, and at this time, the stator base is just socketed on the socket rod 2-3. Then, the first cylinder 2-4 will be started, and its first screw rod extends forward until the return plate 2-5 abuts against the rear side of the stator base. The return plate 2-5 and the rear side of the stator base fit well, which plays a good role in correcting the deviation of the stator base, making it straightened. At the same time, during the process of correcting and straightening the deviation, a good pressing and fixing effect is exerted on the stator base, ensuring that the transmission of the stator base in the next link is more stable. Therefore, after the stator base on the socket rod 2-3 is straightened, it is squeezed and transmitted from the right end of the connecting rod 2-1 to the left end of the connecting rod 2-1, that is, it stops directly below the manipulator structure 3-4 after being transmitted. At this time, the manipulator structure 3-4 will extend downward to clamp the stator base sent directly below it. At the same time when the manipulator structure 3-4 clamps the stator base, the suction cup structure 3-5 will also extend downward at the same time to suck the stator base with the insulating paper inserted directly below it. These two processes are carried out simultaneously. Then, the manipulator structure 3-4 and the suction cup structure 3-5 will slide to the left end of the transverse rod 3-3. Then, the manipulator structure 3-4 and the suction cup structure 3-5 will extend downward at the same time. Among them, the suction cup structure 3-5 extends downward to place the stator base with the insulating paper inserted directly below it at the discharging place. The manipulator structure 3-4 extends downward to socket the stator base that needs to insert the insulating paper on the paper inserting table directly below it. Then, the insulating paper can be inserted into the stator base through the insulating paper inserting machine. Through the manipulator structure 3-4 and the suction cup structure 3-5, the feeding and discharging are carried out synchronously, saving time and greatly improving work efficiency. The stator base is accurately and automatically sent to the paper inserting table of the insulating paper inserting machine, enabling it to insert the insulating paper well.;

[0031] The second suction cup structure 3-5 includes a second cylinder 3-5-1 slidably connected to the transverse rod 3-3. A connecting plate 3-5-2 is fixed to the end of the second lead screw shaft of the second cylinder 3-5-1. A suction cup 3-5-3 is connected below the connecting plate 3-5-2, and two symmetrically distributed small cylinders 3-5-4 are fixed thereon. The telescopic rod 3-5-5 of the small cylinder 3-5-4 is arranged outside the suction cup 3-5-3 and does not contact the suction cup 3-5-3. It should be noted here that a socket column is fixed on the paper inserting table. If the stator base inserted with insulating paper is directly sucked by 3-5-3, it will be blocked by the socket column and the stator base cannot be normally sucked. Therefore, small cylinders 3-5-4 symmetrically arranged at 180 degrees are fixed on the connecting plate 3-5-2, and the telescopic rod 3-5-5 of the small cylinder 3-5-4 is arranged outside the suction cup 3-5-3 and does not contact the suction cup 3-5-3. This structure is matched with another patent of the applicant regarding the paper inserting table. There is a clamping mechanism on both sides of the socket column on the paper inserting table. When the suction cup 3-5-3 sucks the stator base inserted with insulating paper, the clamping mechanism on the paper inserting table is first pressed down by the telescopic rod 3-5-5 of the small cylinder 3-5-4, so that the stator base will be jacked up a certain distance and protrude above the socket column, and thus the stator base can be easily sucked up. This structure mainly enables the stator base on the paper inserting table to be easily sucked by the suction cup structure 3-5 after the insulating paper is inserted, playing a very good auxiliary role.

[0032] Four convex blocks 3-5-2-1 are evenly distributed on the connecting plate 3-5-2. The distance that the left and right convex blocks 3-5-2-1 protrude outward is less than the distance that the front and rear convex blocks 3-5-2-1 protrude outward. By setting the connecting plate 3-5-2 in this form, on the one hand, the suction cup 3-5-3 can be well connected and fixed, and on the other hand, compared with the connecting plate without the convex blocks 3-5-2-1, it has a very good weight reduction effect. In addition, by setting the distance that the left and right convex blocks 3-5-2-1 protrude outward to be less than the distance that the front and rear convex blocks 3-5-2-1 protrude outward, the small cylinders 3-5-4 can be fixed on the part where the front and rear convex blocks 3-5-2-1 are more than the left and right convex blocks 3-5-2-1.

[0033] The socket rod 2-3 includes a cylindrical socket rod body 2-3-1. A frustum 2-3-2 with a smaller upper part and a larger lower part is fixed to the upper end of the socket rod body 2-3-1, which facilitates the stator base to be successfully sleeved on the socket rod 2-3. The size of the socket rod body 2-3-1 is the same as that of the socket hole at the center of the stator base.

[0034] At the middle position of the bottom surface of the sliding table 2-2, a first slider 2-6 is fixed. At the four corners of its bottom surface, support blocks 2-7 are fixed. Inside the support blocks 2-7, second sliders 2-8 are fixed. On the connecting rod 2-1, there are chutes matching the first slider 2-6 and the second slider 2-8. On the upper surfaces of the left and right ends of the connecting rod 2-1, stoppers 2-9 are fixed. The height of the stoppers 2-9 is higher than the height of the sliding table 2-2. An inductor 2-10 is fixed on the stoppers 2-9. Through this setting, the stability of the entire sliding table 2-2 is better and the operation is more stable. Because a first cylinder 2-4 is fixed on the sliding table 2-2 and the first cylinder 2-4 is arranged on one side of the sliding table 2-2, this is likely to cause the center of gravity of the sliding table 2-2 to be unstable, thus leading to unstable operation. Therefore, the sliding table 2-2 is set in this form, greatly improving the stability and ensuring the stability of the operation at the same time. The setting of the stoppers 2-9 plays a very good limiting role, preventing the situation that the sliding table 2-2 slides out of the connecting rod 2-1. The setting of the inductor 2-10 is to sense the distance, to sense the distance between the sliding table 2-2 and the inductor 2-10, so as to ensure that each time the sliding table 2-2 can stay at the position on the connecting rod 2-1 where it needs to stay, ensuring the accuracy.

[0035] There are two first screw shafts of the first cylinder 2-4, which respectively extend from the positions near the left and right edges of the first cylinder 2-4. This setting method makes the aligning effect of the aligning plate 2-5 on the stator seat the best. Among them, the aligning plate 2-5 just fits the side surface of the stator seat. In this way, the forces of the two first screw shafts will act on the two ends of the side surface of the stator seat opposite to the aligning plate 2-5, and it is very easy to align the stator seat, which is very easy and accurate.

[0036] On the surface of the aligning plate 2-5 facing the socket rod 2-3, there are a transverse groove 2-11 and a vertical groove 2-12. By setting the transverse groove 2-11 and the vertical groove 2-12 on the surface of the aligning plate 2-5 facing the socket rod 2-3, the friction force when the aligning plate 2-5 contacts the stator seat is increased, ensuring the stability of the contact.

[0037] The depth and width of the transverse groove 2-11 and the vertical groove 2-12 are both 0.3 mm. By setting the depth and width of the transverse groove 2-11 and the vertical groove 2-12 to 0.3 mm, the transverse groove 2-11 and the vertical groove 2-12 are very narrow and shallow, and will not have any impact on the alignment of the stator seat. However, the grid groove composed of the transverse groove 2-11 and the vertical groove 2-12 has a very good effect of increasing the friction force, ensuring the stability of the contact.

[0038] The lower ends of the left and right sides of the back surface of the horizontal sliding rod 1-2 are respectively fixed to the vertical rods 1-6. A cross rod 1-7 is fixed between the upper ends of the left and right vertical rods 1-6. The cross rod 1-7 is slidably connected to the longitudinal sliding rod 1-3. Through the arrangement of the vertical rods 1-6 and the cross rod 1-7, the stability of the operation of the longitudinal sliding rod 1-3 is greatly improved.

[0039] An electric control box, an alarm lamp 1-8 and an operation button 1-9 are provided on the first support frame 1-1. The electric control box controls the operation of the entire device. When the stator base in the feeding box 1-5 is used up, an alarm will be given; when the insulating paper is used up, an alarm will be given immediately, so that the manipulator structure 3-4 and the second suction cup structure 3-5 will stop immediately to avoid collision during descent; when the stator base handling fails, the machine will stop and alarm. The setting of the operation button 1-9 facilitates operation.

[0040] Working principle: When working, do the preparation work first. The preparation work is to place the stator seats that need to be inserted with insulating paper in a certain order in the discharge box 1-5. There are enough stator seats in the discharge box 1-5, and then start the electric control box. The operation of the entire feeding mechanism is controlled by the electric control box. First, the horizontal slide bar 1-2 and the longitudinal slide bar 1-3 slide to the top of the stator seat to be taken, and then the first suction cup structure 1-4 slides downward along the longitudinal slide bar 1-3 until the first suction cup structure 1-4 absorbs the stator seat directly below it, and then the first suction cup structure 1-4 rises along the longitudinal slide bar 1-3 and returns to its original position, and then the horizontal slide bar 1-2 slides to the left. The suction cup structure 1-4 is sent to the top of the sleeve rod 2-3 of the material conveying mechanism 2, and then the suction cup structure 1-4 will slide downward along the longitudinal slide rod 1-3 until it slides to a place very close to the bottom of the sleeve rod 2-3, and then the suction cup structure 1-4 will be loosened, and the stator seat is just sleeved on the sleeve rod 2-3, and then the first cylinder 2-4 will be started, and its first screw shaft will extend forward until the return plate 2-5 is against the rear side of the stator seat, wherein the return plate 2-5 and the rear side of the stator seat are matched, which has a good correction effect on the stator seat, so that it can be straightened, and at the same time, the stator seat is well pressed and tightened during the correction and straightening process. The role of fixing is to ensure that the transmission of the next link of the stator seat is more stable, so the stator seat on the sleeve rod 2-3 is squeezed and transmitted from the right end of the connecting rod 2-1 to the left end of the connecting rod 2-1 after being straightened, that is, it stops after being transmitted to the bottom of the manipulator structure 3-4. At this time, the manipulator structure 3-4 will extend downward to clamp the stator seat sent to the bottom of it. While the manipulator structure 3-4 clamps the stator seat, the suction cup structure 3-5 will also extend downward at the same time to absorb the stator seat with the insulating paper inserted directly below it. These two processes are carried out simultaneously, and then the manipulator structure 3-4 and the suction cup structure 3-5 will slide to the left end of the transverse rod 3-3. After that, the manipulator structure 3-4 and the suction cup structure 3-5 will extend downward at the same time, wherein the suction cup structure 3-5 extends downward to place the stator seat with the insulating paper inserted therein at the unloading place directly below it, and the manipulator structure 3-4 extends downward to sleeve the stator seat to be inserted with the insulating paper on the paper insertion table directly below it, and then the insulating paper can be inserted into the stator seat by the insulating paper insertion machine. The loading and unloading of materials are carried out synchronously by the manipulator structure 3-4 and the suction cup structure 3-5, which saves time and greatly improves work efficiency, and accurately and automatically delivers the stator seat to the paper insertion table of the insulating paper insertion machine, so that the insulating paper can be well inserted.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
