Description

Technical Field

[0001] The present invention relates to the technical field of motor production, and specifically to a paper embedding equipment for a stator. Background Art

[0002] Paper embedding in the stator is for protecting the insulation of the motor and fixing the coil. The stator is an important component in the motor, which contains coils and magnets. During use, current is generated in the coils and there is voltage. If no insulation treatment is carried out, it may cause a short circuit between the coils or between the coils and other metal components. Insulating paper is an insulating material. By embedding it between the stator coils, it can effectively isolate the coils and other metal components, preventing accidental short circuits of the current. In addition, the insulating paper can also fix the position of the stator coils to ensure that they do not loosen or displace, thus ensuring the normal operation of the motor.

[0003] A paper inserting machine for a flat wire motor disclosed in the patent with the publication number CN219372238U includes a substrate, a conveying mechanism, a feeding and forming mechanism for feeding and forming insulating paper, and an inserting mechanism for inserting the insulating paper into the stator paper slots. The conveying mechanism, the feeding and forming mechanism, and the inserting mechanism are all installed on the substrate; the feeding and forming mechanism is located between the conveying mechanism and the inserting mechanism; the conveying mechanism has a rotation driving component for driving the stator to rotate; the inserting mechanism has an inserting rod. The feeding and forming mechanism feeds the insulating paper to the lower part of the inserting rod, and the inserting rod can descend to correspond to the stator paper slots on the conveying mechanism; through the use of the conveying mechanism, the feeding and forming mechanism, and the inserting mechanism, the automation realizes the conveying of the stator, the feeding and forming of the insulating paper, and the insertion of the insulating paper into the stator paper slots, with high insertion accuracy and reduced defective product rate.

[0004] However, in this patent, due to the elasticity of the insulating paper itself, after being bent, the shape of the insulating paper cannot fit the gap of the stator because of its own elasticity. At this time, the insulating paper cannot be accurately inserted into the pores of the stator. For this reason, a new type of paper embedding equipment is needed to solve this problem. Summary of the Invention

[0014] Preferably, through holes are provided on the bottom of the gas tank and the slide plate, the piston is located above the slide plate, and the end of the fixing pipe away from the connecting pipe is located above the piston.

[0015] Compared with the prior art, the present invention has the following significant advantages:

[0016] First, in the present invention, by setting a fixing component, before installing the insulating paper into the stator, the stator can be inserted into the slot, and the limit block can be inserted into the hole in the center of the stator, so that the limit block and the stator are stuck together, and at the same time, the limit rod will press against the stator under the action of the first spring to prevent the stator from falling out of the slot during the entire working process. After that, during the process of installing the insulating paper, the first motor can be started, and the two sprockets can be driven to rotate by the first motor, thereby driving the limit block to rotate, and the rotation of the limit block can drive the stator to rotate, so as to facilitate the installation of the insulating paper in each hole of the stator;

[0017] Second: In the present invention, by providing a paper embedding component and a forward pushing component, the flat insulating paper can be placed in the paper grooves on the two fixed rods. At this time, the insulating paper will be placed on the top of the bracket. Because the two ends of the insulating paper are respectively supported by the two paper grooves, the positioning of the insulating paper is completed. At this time, the third motor is started, and the third motor will drive the pressing plate to move downward. When the pressing plate moves downward, the two side plates will first support the two ends of the insulating paper. The side plates are made of magnets and the bracket is made of iron. Therefore, the side plates will be attached to the two sides of the bracket during the process of pressing down with the pressing plate, that is, the pressing plate and the two side plates will respectively fit the top and both sides of the bracket, so that the insulating paper is also folded into a shape with the same contour as the surface of the bracket, and the insulating paper fits the surface of the bracket;

[0018] Third: In the present invention, by setting a pressure regulating component, when the third motor is started, the output shaft of the third motor will drive the pressure rod to move downward. When the pressure rod moves downward, it will drive the slide plate in the gas tank to move downward. The downward movement of the slide plate will cause the second spring to move downward, and then the piston to move downward. When the piston moves downward, the space at the top of the gas tank increases, and the air pressure decreases. The top of the gas tank is connected to the fixed pipe and the connecting pipe, and the connecting pipe is connected to the fixed sleeve. Therefore, negative pressure is generated in the fixed sleeve and the telescopic pipe. Therefore, the bracket is also in a negative pressure state. Multiple air holes take air into the bracket from the outside, and except for one air hole at the top of the bracket which is in an open state, the other air holes are covered by insulating paper. Therefore, the negative pressure causes the insulating paper to be firmly adsorbed on the surface of the bracket to prevent the insulating paper from being deformed due to its own elasticity.

[0019] Fourth: In the present invention, after the insulating paper is bent and fixed on the bracket, the second motor can be started. After the second motor is started, its output shaft drives the connecting rod to push forward, and the connecting rod drives the telescopic tube to move forward, thereby causing the bracket to move forward. The insulating paper is adsorbed on the surface of the bracket. Therefore, the bracket and the insulating paper will be sent into the pores of the stator together. After the bracket sends the insulating paper into the pores of the stator, the third motor is started to move the output shaft of the third motor upward. At this time, the slide plate and the piston in the air tank move upward, the air pressure at the top of the air tank increases, and the air holes on the bracket exhaust outward. Therefore, the insulating paper on the surface of the bracket will be pushed outward. At this time, the second motor is started again to retract the bracket with the second motor, then the insulating paper is left in the pores of the stator, and the bracket itself resets.

[0030] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. 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 belong to the scope of protection of the present invention.

[0031] The present invention provides a paper inserting equipment for a stator through improvement. The technical solution of the present invention is as follows:

[0032] As Figures 1 - 7 shown, a paper inserting equipment for a stator includes a base 1. A fixing component 2 is arranged on the base 1. The fixing component 2 includes a first motor 22, a sprocket 23, a chain 24 and a limit block 25. A slot 21 is opened on the base 1. The first motor 22 is fixedly connected to the inside of the base 1. The limit block 25 is rotatably connected to the inside of the slot 21. Two sprockets 23 are respectively fixedly connected to the limit block 25 and the output shaft of the first motor 22. The chain 24 is sleeved on the two sprockets 23. A forward pushing component 3 is arranged on the base 1. The forward pushing component 3 includes a second motor 31, a fixed sleeve 32, a telescopic tube 33, a bracket 34 and a connecting rod 36. The second motor 31 is fixedly connected to the base 1. The fixed sleeve 32 is fixedly connected to the second motor 31. The telescopic tube 33 is slidably connected to the inside of the fixed sleeve 32. The bracket 34 is fixedly connected to the telescopic tube 33. A plurality of air holes 35 are opened on the bracket 34. The connecting rod 36 is fixedly connected between the output shaft of the second motor 31 and the telescopic tube 33. A paper inserting component 4 is arranged on the base 1. The paper inserting component 4 includes a ring 41, a frame 42, a third motor 43, a pressing plate 44 and a side plate 46. Two rings 41 are fixedly connected to the base 1. The frame 42 is fixedly connected to the two rings 41. The third motor 43 is fixedly connected to the frame 42. The pressing plate 44 is fixedly connected to the output shaft of the third motor 43. Two side plates 46 are respectively hinged to both sides of the pressing plate 44. A pressure regulating component 5 is arranged on the base 1.

[0033] The insulating paper can be placed on the bracket 34. When the pressure plate 44 moves downward, the two side plates 46 will first contact the insulating paper, thereby folding the insulating paper from both ends, so that the insulating paper is bent into a shape that fits the surface of the bracket 34. The shape of the bracket 34 is the same as the pore shape of the stator 29. At this time, you only need to send the insulating paper and the bracket 34 into the pores of the stator 29 together.

[0034] Further, such as Figure 1 and Figure 3 As shown, the fixing assembly 2 also includes a limiting rod 27 and a first spring 28. A bottom groove 26 is provided on the base 1. The limiting rod 27 is slidably connected to the inside of the bottom groove 26. The first spring 28 is fixedly connected between the limiting rod 27 and the inner wall of the bottom groove 26. Before inserting the stator 29 into the slot 21, it is necessary to push the limiting rod 27 aside, then put the stator 29 into the slot 21, and insert the stator 29 into the limiting block 25. Then, the limiting rod 27 is released. The limiting rod 27 will press against the stator 29 under the action of the first spring 28, thereby preventing the stator 29 from falling out of the slot 21.

[0035] Further, such as Figure 5 As shown, the paper embedded component 4 also includes a spring hinge 45, and multiple spring hinges 45 are respectively arranged on both sides of the pressure plate 44, and two side panels 46 are respectively hinged on the multiple spring hinges 45. The elastic force of the spring hinges 45 enables the two side panels 46 to maintain a vertical state with the pressure plate 44 in a natural state, and the insulating paper can be folded when the side panels 46 move downward.

[0036] Furthermore, the side plate 46 is made of magnetic material and the bracket 34 is made of iron. When the side plate 46 completes folding the insulating paper, it will also fit the surface of the bracket 34 due to the magnetic attraction, thereby ensuring that the shape of the insulating paper can also fit the surface of the bracket 34.

[0037] Further, such as Figure 4 and Figure 5 As shown, the paper embedding assembly 4 also includes a fixing rod 47 and a paper slot 48. The two fixing rods 47 are fixedly connected to the inside of the two rings 41. The two paper slots 48 are respectively opened on the two fixing rods 47. The insulating paper can be placed on the top of the bracket 34. The height of the paper slot 48 is the same as the top height of the bracket 34. Therefore, the insulating paper can be accurately positioned with the help of the two paper slots 48.

[0038] Further, such as Figure 5 As shown, the fixing rod 47 is in an "L" shape, and the two fixing rods 47 are symmetrically arranged on both sides of the bracket 34. When the insulating paper is placed in the paper slot 48, the front end of the insulating paper can be against the front end of the fixing rod 47 to ensure that the front end of the insulating paper does not exceed the bracket 34, further enabling the insulating paper to be accurately positioned during the placement process.

[0039] Further, as shown in Figure 1 and Figure 7 shown, the pressure regulating component 5 includes an air tank 51, a pressure rod 55 and a connecting pipe 57. The pressure rod 55 is fixedly connected to the output shaft of the third motor 43. The air tank 51 is fixedly connected to the base 1, and the pressure rod 55 is slidably connected to the air tank 51. One end of the connecting pipe 57 is fixedly connected to the bottom of the air tank 51, and the other end of the connecting pipe 57 is fixedly connected to the fixed sleeve 32. When positive pressure and negative pressure are generated in the air tank 51, they can both be transmitted to the inside of the fixed sleeve 32 through the connecting pipe 57. The interiors of the fixed sleeve 32, the telescopic pipe 33 and the bracket 34 are all connected. Therefore, positive pressure and negative pressure can be generated inside the bracket 34 under the action of the air tank 51. When negative pressure is generated, the insulating paper will be sucked onto the surface of the bracket 34. When positive pressure is generated, it helps to separate the insulating paper from the bracket 34.

[0040] Further, as shown in Figure 7 shown, the pressure regulating component 5 further includes a sliding plate 52, a piston 53, a second spring 54 and a fixed pipe 56. The sliding plate 52 and the piston 53 are both slidably connected to the inside of the air tank 51. The second spring 54 is fixedly connected between the sliding plate 52 and the piston 53. The fixed pipe 56 is fixedly connected to the bottom inner wall of the air tank 51, and both the sliding plate 52 and the piston 53 are slidably connected to the fixed pipe 56. The bottom end of the fixed pipe 56 is communicated with the connecting pipe 57. The pressure rod 55 can drive the sliding plate 52 to move downward, and then drive the second spring 54 to move downward. Under the pulling of the second spring 54, the piston 53 moves downward, so that negative pressure can be formed in the air tank 51, and then negative pressure is generated in the bracket 34. On the contrary, positive pressure is generated in the bracket 34. The effect of setting the second spring 54 is to make the movement of the piston 53 not completely synchronized with the sliding plate 52, avoiding excessive or too small air pressure in the bracket 34, so as to prevent the insulating paper from deforming or cracking.

[0041] Further, as shown in Figure 7 shown, through holes 58 are provided in both the bottom of the air tank 51 and the sliding plate 52. The piston 53 is located above the sliding plate 52, and one end of the fixed pipe 56 away from the connecting pipe 57 is located above the piston 53. The purpose of setting the through holes 58 is to keep the standard atmospheric pressure under the sliding plate 52 all the time, so as to facilitate the sliding plate 52 to move freely with the pressure rod 55.

[0042] The specific working method is: first, the insulating paper is cut into a suitable size by a cutting device; before the insulating paper is installed in the stator 29, the stator 29 is inserted into the slot 21, and the limit block 25 is inserted into the hole in the center of the stator 29, so that the limit block 25 and the stator 29 are stuck together, and at the same time, the limit rod 27 will resist the stator 29 under the action of the first spring 28, so as to prevent the stator 29 from falling out of the slot 21 during the whole working process; then, in the process of installing the insulating paper, the first motor 22 can be started, and the two sprockets 23 can be driven to rotate by the first motor 22, thereby driving the limit block 25 to rotate, and the rotation of the limit block 25 can drive the stator 29 to rotate, so as to facilitate the installation of the insulating paper for each hole of the stator 29.

[0043] Put the flat insulating paper into the paper slots 48 on the two fixing rods 47. At this time, the insulating paper will be placed on the top of the bracket 34. Because the two ends of the insulating paper are respectively supported by the two paper slots 48, the positioning of the insulating paper is completed. At this time, the third motor 43 is started, and the third motor 43 will drive the pressing plate 44 to move downward. When the pressing plate 44 moves downward, the two side plates 46 will first support the two ends of the insulating paper. The side plates 46 are made of magnets, and the bracket 34 is made of iron. Therefore, the side plates 46 will fit to the two sides of the bracket 34 during the process of pressing the pressing plate 44 downward, that is, the pressing plate 44 and the two side plates 46 will fit the top and both sides of the bracket 34 respectively, so that the insulating paper is also folded into the same shape as the surface contour of the bracket 34, and the insulating paper fits the surface of the bracket 34.

[0044] When the third motor 43 is started, the output shaft of the third motor 43 will drive the pressure rod 55 to move downward. When the pressure rod 55 moves downward, it will drive the slide plate 52 in the gas tank 51 to move downward. The downward movement of the slide plate 52 will cause the second spring 54 to move downward, and then the piston 53 to move downward. When the piston 53 moves downward, the space at the top of the gas tank 51 increases and the air pressure decreases. The top of the gas tank 51 is connected to the fixed pipe 56 and the connecting pipe 57, and the connecting pipe 57 is connected to the fixed sleeve 32. Therefore, negative pressure is generated in the fixed sleeve 32 and the telescopic tube 33. Therefore, the bracket 34 is also in a negative pressure state. Multiple air holes 35 take air into the bracket 34 from the outside, and except for one air hole 35 at the top of the bracket 34 which is in an open state, the other air holes 35 are covered by insulating paper. Therefore, the negative pressure will cause the insulating paper to be firmly adsorbed on the surface of the bracket 34 to prevent the insulating paper from being deformed due to its own elasticity.

[0045] After starting the second motor 31, after the second motor 31 starts, its output shaft drives the connecting rod 36 to push forward. The connecting rod 36 drives the telescopic tube 33 to move forward, and then the bracket 34 moves forward. The insulating paper is adsorbed on the surface of the bracket 34. Therefore, the bracket 34 and the insulating paper will be sent into the pores of the stator 29 together. After the bracket 34 sends the insulating paper into the pores of the stator 29, start the third motor 43 to move the output shaft of the third motor 43 upward. At this time, the slide plate 52 and the piston 53 in the air tank 51 move upward, the air pressure at the top of the air tank 51 increases, and the air holes 35 on the bracket 34 exhaust outward. Therefore, the insulating paper on the surface of the bracket 34 will be pushed outward. At this time, start the second motor 31 again to retract the bracket 34 with the second motor 31, then the insulating paper is left in the pores of the stator 29, and the bracket 34 resets itself.

[0046] After that, start the first motor 22 to rotate the stator 29, and repeat the above steps to install the insulating paper into each pore of the stator 29 in turn.

[0047] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above technical means, but also include the technical solutions composed of equivalent replacements of the above technical features. Matters not covered in the present invention belong to the common general knowledge of those skilled in the art.
