Description

Technical Field

[0001] This application relates to the technical field of motor production and manufacturing, and in particular to an insulating paper installation device. Background Art

[0002] The stator slots are arranged on the motor stator core and are used to embed the exciting winding. In order to prevent conduction between the exciting winding and the motor stator core, insulating paper needs to be inserted into the stator slots.

[0003] In the patent with the publication number CN206564526U, an automatic paper inserting machine is disclosed. When in use, the insulating paper is sleeved on the support disk, and the rotation of the motor shaft is controlled to drive the first bevel gear to rotate. The first bevel gear drives the first vertical rod, the first spur gear and the third spur gear to rotate. The third spur gear drives the fourth spur gear to rotate. The first spur gear drives the second spur gear, the second vertical rod and the friction wheel to rotate. The insulating paper is conveyed to the cutting assembly through the friction wheel for cutting. After the insulating paper is cut and formed, it is conveyed to the inner cavity of the forming groove. The ejecting assembly is used to push the insulating paper in the inner cavity of the forming groove. The insulating paper is pushed through the paper outlet hole into the groove of the mold. Before inserting the insulating paper, due to reasons such as dust in the workshop environment, the storage conditions of the insulating paper are not clean enough, or the insulating paper is exposed to the external environment during transportation and adsorbs dust by itself, there is dust on the surface of the insulating paper. If the insulating paper before paper insertion is not dust-removed and is directly installed in the stator slot, the dust may hinder the heat dissipation, increase the thermal resistance of the stator, cause the temperature inside the motor to rise, and affect the cooling efficiency and service life of the motor. Summary of the Utility Model

[0004] The purpose of this application is to propose an insulating paper installation device for the above problems existing in the prior art.

[0005] This application can be realized by the following technical solutions: An insulating paper installation device includes an insulating paper tube, a fixing frame, an automatic paper inserting machine body, a conveying roller and a dust sticking roller. The insulating paper tube can rotate so that the insulating paper tube can unwind the insulating paper; the fixing frame can support the insulating paper; the automatic paper inserting machine body is used for installing the insulating paper on the stator; the conveying roller is rotatably connected to the fixing frame, and the conveying roller is used for conveying the insulating paper into the automatic paper inserting machine body; there are two dust sticking rollers, which are respectively used for sticking and removing the dust on the upper and lower surfaces of the insulating paper before contacting the conveying roller.

[0006] In the above technical solution, the rotation of the insulating paper tube can unwind the insulating paper. The conveying roller is used to feed the insulating paper into the interior of the paper inserting machine body. The paper inserting machine body can cut and fold the insulating paper, and then the insulating paper can be pushed into the stator slot. Before the insulating paper contacts the conveying roller, the upper and lower surfaces of the insulating paper can respectively contact two dust sticking roller cylinders. The dust sticking roller cylinders can remove the dust attached to the insulating paper to ensure the cleanliness of the insulating paper entering the paper inserting machine body.

[0007] Further, the dust sticking roller cylinder includes a cylinder core and several layers of dust sticking paper adhered to the cylinder core. The cylinder core forces the dust sticking paper to fit against the insulating paper through a pressing component.

[0008] In the above technical solution, since several layers of dust sticking paper are adhered to the cylinder core, when the amount of dust adhered to one layer of dust sticking paper reaches saturation, this layer of dust sticking paper needs to be torn off so that the next unused layer of dust sticking paper can contact the insulating paper. During this process, due to the overall thickness reduction of several layers of dust sticking paper, the new dust sticking paper cannot maintain contact with the insulating paper after one layer of dust sticking paper is torn off. The pressing component can ensure that the next layer of dust sticking paper can still maintain contact with the insulating paper after one layer of dust sticking paper is torn off.

[0009] Further, the pressing component includes a fixed block rotatably installed on the cylinder core, a spring that forces the fixed block to approach the insulating paper, and a sleeve that guides the movement paths of the spring and the fixed block. The sleeve is vertically placed and fixedly installed on the fixed frame. The fixed block is slidably connected to the inner wall of the sleeve and can slide along the length direction of the sleeve. A long slot for the cylinder core to pass through is provided on the length side wall of the sleeve, and the length direction of the long slot is the same as the length direction of the sleeve.

[0010] In the above technical solution, the spring can force the dust sticking roller cylinder to approach the insulating paper so that the dust sticking paper maintains contact with the insulating paper.

[0011] Further, an anti-static coating is applied on the fixed frame, and the anti-static coating can contact the insulating paper.

[0012] In the above technical solution, the anti-static coating is not easily adsorbed with dust. Compared with the insulating paper directly contacting the fixed frame, it can reduce the possibility of the lower surface of the insulating paper being contaminated with dust again after being cleaned.

[0013] Further, the conveying roller is an anti-static rubber roller.

[0014] In the above technical solution, the anti-static rubber roller is not easily sticky to dust, which can reduce the possibility of the dust on the conveying roller sticking to the upper surface of the insulating paper during the process of the conveying roller transporting the insulating paper.

[0015] Further, a dust cover is detachably mounted on the fixing frame. The dust cover covers the upper surface of the insulating paper tube, the fixing frame, the dust sticking roller and the conveying roller, and the dust cover is communicated with the inside of the paper inserting machine body.

[0016] In the above technical solution, during the paper feeding process of the paper inserting machine body, the dust cover can be covered on the insulating paper tube, the dust sticking roller and the conveying roller, so as to reduce the possibility of dust adhering to the insulating paper cleaned by the dust sticking roller during the paper feeding process.

[0017] Further, the dust cover is hinged to the fixing frame, and the dust cover is made of a transparent material.

[0018] In the above technical solution, the dust cover is hinged to the fixing frame, which is convenient for opening and closing the dust cover. The transparent dust cover is convenient for observing the paper feeding process, so as to facilitate timely maintenance when a fault is found.

[0019] Further, the insulating paper tube includes a rotating cylinder and several layers of insulating paper wound around the rotating cylinder. The fixing frame is rotatably connected with two rotating blocks. Each rotating block is provided with a clamping groove, and the two clamping grooves are correspondingly arranged for the two ends of the rotating cylinder in the length direction to be clamped into. The rotating cylinder and the rotating block are penetrated by the same bolt, and the bolt is threadedly connected with a nut.

[0020] In the above technical solution, by arranging the rotating blocks and connecting the rotating blocks with the rotating cylinder through bolts and nuts, the installation and disassembly of the insulating paper tube can be facilitated.

[0021] In summary, the present application has the following technical effects: the rotation of the insulating paper tube can unwind the insulating paper, the conveying roller is used to feed the insulating paper into the inside of the paper inserting machine body, and the paper inserting machine body can cut and fold the insulating paper, and then the insulating paper can be pushed into the stator slot. Before the insulating paper contacts the conveying roller, the upper and lower surfaces of the insulating paper can respectively contact the two dust sticking rollers, and the dust sticking rollers can stick and remove the dust attached to the insulating paper to ensure the cleanliness of the insulating paper entering the paper inserting machine body.

[0028] Please refer to the Figure 1 and Figure 2 of the accompanying drawings of the specification. An embodiment of the present application provides an insulating paper installation device, including an inserting paper machine body 3. The inserting paper machine body 3 is provided with a paper inlet 31 for the insulating paper 11 to enter. A fixed frame 2 is detachably installed on the outer wall of the inserting paper machine body 3 where the paper inlet 31 is located. The lower end of the fixed frame 2 is fixed to the ground. An insulating paper tube 1 is placed above the fixed frame 2. The insulating paper tube 1 includes a rotatable rotating tube 12 and several layers of insulating paper 11 wound around the rotating tube 12. The rotating tube 12 can rotate to unwind the insulating paper 11. The fixed frame 2 can support the insulating paper 11. The fixed frame 2 is coated with an antistatic coating 7 that can contact the insulating paper 11. A conveying roller 4 is rotatably connected to the fixed frame 2. The length direction of the conveying roller 4 is the same as the width direction of the fixed frame 2 and is horizontally placed. The conveying roller 4 is driven by a motor 14 to rotate clockwise. The outer wall of the axial direction of the conveying roller 4 can contact the insulating paper 11 on the antistatic coating 7 to convey the insulating paper 11 into the paper inlet 31. The inserting paper machine body 3 is provided with a paper cutting, paper folding and paper pushing mechanism. The paper cutting mechanism is used to cut the insulating paper 11, the paper folding mechanism is used to fold the insulating paper 11 into the shape required to fit the stator slot, and the paper pushing mechanism is used to push the folded insulating paper 11 into the stator slot, and the installation of the insulating paper 11 is completed.

[0029] Please refer to the Figure 1 and Figure 2 of the accompanying drawings of the specification. During the production process, due to the presence of dust in the workshop environment and other reasons, dust will adhere to the surface of the insulating paper 11. Two dust sticking rollers 5 are placed between the rotating tube 12 and the conveying roller 4. The dust sticking roller 5 includes a tube core 51 and several layers of dust sticking paper 52 adhered to the tube core 51. The dust sticking paper 52 on the two dust sticking rollers 5 can respectively contact the upper surface and the lower surface of the insulating paper 11. During the process of the conveying roller 4 conveying the insulating paper 11, the insulating paper 11 can contact the dust sticking paper 52 to drive the dust sticking roller 5 to rotate. During this process, the dust sticking paper 52 can remove the dust on the surface of the insulating paper 11 to ensure the cleanliness of the insulating paper 11 before contacting the conveying roller 4. Before the worker uses the dust sticking roller 5, the dust sticking roller 5 with an appropriate adhesive force can be selected through tests to prevent the dust sticking roller 5 from damaging the insulating paper.

[0030] Please refer to the attached drawings of the specification Figure 3 , when the dust adhered to the first layer of dust sticking paper 52 reaches saturation, the first layer of dust sticking paper 52 can be torn off to use the next layer of dust sticking paper 52. After tearing off one layer of dust sticking paper 52, the overall thickness of several layers of dust sticking paper 52 used becomes thinner, resulting in the next layer of dust sticking paper 52 being unable to fit with the insulating paper 11. Therefore, the core 51 presses itself against the insulating paper 11 through a pressing component 6. The pressing component 6 includes a sleeve 63 fixedly installed on the fixed frame 2 and placed vertically. There are two sleeves 63 in total. At both ends of the core 51 in the length direction, a fixed block 61 is rotatably connected. The core 51 can rotate relative to the fixed block 61. The fixed block 61 is slidably connected to the inner wall of the sleeve 63 and can slide along the length direction of the sleeve 63. At both ends of the inner wall of the sleeve 63 in the length direction, a spring 62 is fixedly installed. The length direction of the spring 62 is the same as the length direction of the sleeve 63 and is placed vertically. The spring 62 is a compression spring 62. At one end of the two springs 62 close to each other, a fixed block 61 is fixedly installed. The two fixed blocks 61 in the same sleeve 63 are respectively rotatably connected to the two cores 51. There are two fixed blocks 61 and two springs 62 in each of the two sleeves 63. A long slot 631 for the two cores 51 to pass through is opened on the length side wall of the sleeve 63. The length direction of the long slot 631 is the same as the length direction of the sleeve 63. The long slot 631 is used to guide the movement path of the core 51 so that the core 51 can vertically and linearly approach the insulating paper 11. This design enables the next layer of dust sticking paper 52 to still remain in contact with the unrolled insulating paper 11 after one layer of dust sticking paper 52 is torn off.

[0031] Please refer to the attached drawings of the specification Figure 1 , the anti-static coating 7 can contact the lower surface of the insulating paper 11, and the conveying roller 4 is an anti-static rubber roller. The rubber of the anti-static rubber roller has been anti-static treated, for example, an anti-static agent for rubber is added to the rubber, so that the conveying roller 4 is not likely to adhere dust due to static electricity. This design can reduce the possibility of the insulating paper 11 being cleaned by the dust sticking roller 5 and then adhering dust again during the conveying process by the conveying roller 4. The fixed frame 2 is also hinged with a dust-proof cover 8. The lower end of the dust-proof cover 8 can abut against the anti-static coating 7, and one end of the dust-proof cover 8 close to the paper inserting machine body 3 abuts against the outer wall of the paper inserting machine body 3 where the paper inlet 31 is located, so that the dust-proof cover 8 can cover the conveying roller 4, the upper surface of the fixed frame 2, the dust sticking roller 5 and the insulating paper tube 1, and the inside of the dust-proof cover 8 can communicate with the inside of the paper inserting machine body 3 through the paper inlet 31, so that the insulating paper 11 in the dust-proof cover 8 can enter the inside of the paper inserting machine body 3 through the paper inlet 31. By setting the dust-proof cover 8, the possibility of dust falling on the insulating paper 11 can be reduced. The dust-proof cover 8 is made of a transparent material. In this embodiment, the dust-proof cover 8 is made of transparent acrylic material, so that workers can timely detect and repair any faults during the paper feeding process.

[0032] Please refer to the attached drawings of the specificationFigure 4 Two rotating blocks 9 are rotatably connected to the fixing frame 2. The two rotating blocks 9 are arranged oppositely. Each of the two rotating blocks 9 is provided with a clamping groove 91. The two clamping grooves 91 are arranged in one-to-one correspondence for the two ends in the length direction of the rotating cylinder 12 to be clamped into. A same bolt 10 passes through the rotating block 9 and the rotating cylinder 12, and the bolt 10 is threadedly connected with a nut 13 so that the position of the rotating cylinder 12 relative to the rotating block 9 is fixed. This design facilitates the disassembly and installation of the rotating cylinder 12, so that the insulating paper 11 on the rotating cylinder 12 can be quickly disassembled and replaced after being used up.

[0033] The working principle of this embodiment: First, install the rotating cylinder 12 on the rotating block 9, then pass one end of the insulating paper 11 between the two dust-removing roller cylinders 5, and then place the insulating paper 11 between the anti-static coating 7 and the conveying roller 4. At this time, the outer wall of the axial direction of the conveying roller 4 can contact the insulating paper 11. Start the motor 14 to drive the conveying roller 4 to rotate, and the conveying roller 4 can start to convey the insulating paper 11. During the conveying process of the insulating paper 11, the upper and lower surfaces can respectively contact the two dust-removing roller cylinders 5, so as to remove the dust on the upper and lower surfaces of the insulating paper 11, which is relatively convenient.

[0034] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
