Description

[0002] The stator paper is embedded to protect the insulation of the motor and fix the coil. The stator is an important component of the motor. It contains coils and magnets. During use, the coils will generate current and voltage. If no insulation is performed, it may cause a short circuit between the coils or between the coils and other metal parts. Insulation paper is an insulating material. By embedding it between the stator coils, it can effectively isolate the coils and other metal parts to prevent accidental short circuits of the current. In addition, the insulation paper can also fix the position of the stator coil to ensure that it will not loosen or shift, thereby ensuring the normal operation of the motor.

At this time, the insulating paper cannot be accurately inserted into the pores of the stator. Therefore, a new type of paper embedding equipment is needed to solve this problem. Summary of the invention

[0015] Compared with the prior art, the present invention has the following significant advantages: 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; 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; 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. Fourthly: 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 moving the bracket forward. The insulating paper is adsorbed on the surface of the bracket, so 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 and the piston in the gas tank move upward, the air pressure at the top of the gas tank increases, and the air holes on the bracket exhaust outward, so 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, and the insulating paper is left in the pores of the stator, and the bracket itself is reset.

[0018] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention provides a stator paper embedding device through improvement. The technical solution of the present invention is: like Figure 1-Figure 7 As shown, a paper-embedded device for a stator includes a base 1, a fixing assembly 2 is arranged on the base 1, the fixing assembly 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 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 push assembly 3 is arranged on the base 1, the forward push assembly 3 includes a second motor 31, a fixing 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 fixing sleeve 32 is fixedly connected to the second On the 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, and 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 embedding assembly 4 is arranged on the base 1. The paper embedding assembly 4 includes a ring 41, a frame 42, a third motor 43, a pressure plate 44 and a side plate 46. The 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 pressure plate 44 is fixedly connected to the output shaft of the third motor 43, and the two side plates 46 are respectively hinged on the two sides of the pressure plate 44. A pressure regulating assembly 5 is arranged on the base 1.

[0020] 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.

[0021] Further, such as Figure 1 and Figure 3As 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] Further, such as Figure 1 and Figure 7As shown, the pressure regulating assembly 5 includes a gas 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 gas tank 51 is fixedly connected to the base 1, and the pressure rod 55 is slidably connected to the gas tank 51. One end of the connecting pipe 57 is fixedly connected to the bottom of the gas 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 gas tank 51, they can be transmitted to the fixed sleeve 32 through the connecting pipe 57, and the interiors of the fixed sleeve 32, the telescopic tube 33 and the bracket 34 are all connected. Therefore, the interior of the bracket 34 can generate positive pressure and negative pressure under the action of the gas 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.

[0027] Further, such as Figure 7 As shown, the pressure regulating assembly 5 also includes a slide plate 52, a piston 53, a second spring 54 and a fixed tube 56. The slide plate 52 and the piston 53 are both slidably connected to the inside of the gas tank 51. The second spring 54 is fixedly connected between the slide plate 52 and the piston 53. The fixed tube 56 is fixedly connected to the bottom inner wall of the gas tank 51, and the slide plate 52 and the piston 53 are both slidably connected to the fixed tube 56. The bottom end of the fixed tube 56 is connected to the connecting tube 57. The pressure rod 55 can drive the slide plate 52 to move downward, thereby moving the second spring 54 downward. Under the traction of the second spring 54, the piston 53 moves downward, which can form a negative pressure in the gas tank 51, thereby generating a negative pressure in the bracket 34, and vice versa, a positive pressure is generated in the bracket 34. The effect of setting the second spring 54 is that the movement of the piston 53 is not completely synchronized with the slide plate 52, so as to avoid excessive or insufficient air pressure in the bracket 34, thereby deforming or rupturing the insulating paper.

[0028] Further, such as Figure 7 As shown, through holes 58 are provided on the bottom of the gas tank 51 and the slide plate 52, the piston 53 is located above the slide plate 52, and the end of the fixed tube 56 away from the connecting tube 57 is located above the piston 53. The purpose of setting the through hole 58 is to always maintain the standard atmospheric pressure under the slide plate 52 so that the slide plate 52 can move freely with the pressure rod 55.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] Then, the second motor 31 is started. After the second motor 31 is started, its output shaft drives the connecting rod 36 to push forward, and the connecting rod 36 drives the telescopic tube 33 to move forward, thereby moving the bracket 34 forward. The insulating paper is adsorbed on the surface of the bracket 34, so 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, the third motor 43 is started to move the output shaft of the third motor 43 upward. At this time, the slide plate 52 and the piston 53 in the gas tank 51 move upward, and the air pressure at the top of the gas tank 51 increases. The air holes 35 on the bracket 34 exhaust air outward, so that the insulating paper on the surface of the bracket 34 will be pushed outward. At this time, the second motor 31 is started again to make the second motor 31 retract with the bracket 34, and the insulating paper is left in the pores of the stator 29, and the bracket 34 resets itself.

[0033] Then, the first motor 22 is started to rotate the stator 29 , and the above steps are repeated to install the insulating paper into each hole of the stator 29 in sequence.

[0034] 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 technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
