Description

Technical Field

[0001] The invention relates to the technical field of enameled wire processing, and in particular to a gold alloy self-adhesive enameled wire and a preparation method thereof. Background Art

[0002] Alloy enameled wire is a main type of winding wire, consisting of a conductor and an insulating layer. Self-adhesive enameled wire is a special type of enameled wire. It is an ordinary enameled wire with an additional layer of self-adhesive paint coated on the surface. The wound paint will undergo a chemical reaction under specific conditions and can be bonded into shape after heating or treatment with alcohol solvents, eliminating auxiliary materials and processes such as skeletons and tapes.

[0003] The invention patent with authorization announcement number CN 112735672 B discloses a gold enameled wire manufacturing and forming process. The alloy enameled wire manufacturing and forming process adopts the following alloy enameled wire manufacturing and forming equipment. The alloy enameled wire manufacturing and forming equipment includes a first mounting plate, a wire-releasing roller, a wire-receiving roller, a gear, a motor and a pretreatment device. The design of the nylon wire and the spring spring in the invention enables the clamping device to maintain dynamic balance according to the wire-receiving progress of the alloy enameled wire by the wire-receiving roller, thereby improving the stability of the invention.

[0004] However, after actual application by technicians in this field, it was found that the above process still has some shortcomings. The most obvious one is that in order to ensure the grinding effect, the operator needs to manually replace the sandpaper attached to the inner surface of the arc-shaped grinding block regularly. During the actual replacement process, the operator not only needs to manually remove the used sandpaper and clean the residual glue, but also needs to manually attach new sandpaper. In addition, since the enameled wire is relatively thin, it is extremely difficult to operate the sandpaper with a width of only one-third of the circumference of the enameled wire during actual attachment. It is too manpower-consuming and has a great impact on the grinding efficiency of the enameled wire. Moreover, the above-mentioned replacement operation can only be performed after the grinding is completed, and is not applicable to the situation where the sandpaper used for grinding needs to be replaced during the grinding process.

[0005] Therefore, it is necessary to invent a gold alloy self-adhesive enameled wire and a preparation method thereof to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a gold alloy self-adhesive enameled wire and a preparation method thereof. A positioning mechanism, a multiple driving mechanism, a one-way switching mechanism, a switching grinding mechanism, an elastic locking mechanism and a limit trigger mechanism are provided so that four groups of switching grinding mechanisms can be used to form cylindrical grinding sandpaper to complete the grinding of the base insulating layer enameled wire. During this process, the elastic locking mechanism locks the switching grinding mechanism to prevent the strip sandpaper from moving randomly. Later, during the grinding process or non-grinding process, when part of the strip sandpaper in contact with the base insulating layer enameled wire needs to be replaced, the multiple driving mechanism drives the left side of the one-way switching mechanism, and then the one-way switching mechanism drives the adjacent switching grinding mechanism, thereby completing the switching of the contact position between the strip sandpaper and the base insulating layer enameled wire. Subsequently, due to the obstruction of the limit trigger mechanism, the switching grinding mechanism cannot continue to move left, and at the same time, the multiple driving mechanism locks the one-way switching mechanism. The switching mechanism is triggered, thereby releasing the one-way switching mechanism from engaging with the switching grinding mechanism, and then the multiple driving mechanisms drive the one-way switching mechanism to move right and reset, until the one-way switching mechanism is triggered by the limit trigger mechanism to realize recovery, so as to solve the problem proposed in the above background technology that in order to ensure the grinding effect, the operator needs to manually replace the sandpaper attached to the inner surface of the arc-shaped grinding block regularly. During the actual replacement process, the operator not only needs to manually remove the used sandpaper and clean the residual glue, but also needs to manually attach the new sandpaper. In addition, since the enameled wire is relatively thin, the sandpaper with a width of only one-third of the circumference of the enameled wire is extremely difficult to operate during actual attachment. It is too labor-intensive and has a great impact on the grinding efficiency of the enameled wire. Moreover, the above replacement operation can only be performed after the grinding is completed, and is not applicable to the situation where the sandpaper used for grinding needs to be replaced during the grinding process.

[0018] The strip of sandpaper passes around the adjacent arc-shaped positioning plates and its two ends are fixedly connected to two retracting rollers respectively. The strip of sandpaper is wound around the outside of the left retracting roller. The U-shaped frame is fixedly connected to the inner wall of the shell.

[0023] Preferably, the method specifically comprises the following steps:

[0024] S1. Put the basic insulating paint into the paint tank of the enameling wire machine, start the machine for wire running, and the gold alloy wire core passes through the paint tank and is heated and cured in a drying oven to obtain the basic insulating layer enameled wire;

[0025] The end of the base insulating layer enameled wire is passed through four arc-shaped positioning plates and a hollow reciprocating screw, and then the end is connected to the winding device, so that the winding device continues to pull the base insulating layer enameled wire. During the pulling process, four arc-shaped strip sandpapers formed under the action of the arc-shaped positioning plates grind the outer surface of the base insulating layer enameled wire;

[0026] The self-adhesive insulating varnish is placed in the varnish tank of the next enameling wire machine, the machine is turned on for wiring, the polished base insulating layer enameled wire passes through the varnish tank and is heated and cured in a drying oven, and a certain degree of cross-linking reaction is performed to form a semi-cured self-adhesive insulating layer, that is, a gold alloy self-adhesive enameled wire is obtained;

[0027] S2. During the grinding process or the non-grinding process, when part of the strip sandpaper in contact with the base insulating layer enameled wire needs to be replaced, the drive motor is started. After the drive motor is started, the hollow reciprocating screw is driven to rotate through the first gear. When the hollow reciprocating screw rotates, the outer sleeve is driven to move leftward. When the outer sleeve moves leftward, the inner sleeve is driven to move leftward through the first spring, and the push plate is driven to move leftward through the outer sleeve plate;

[0028] S3, when the inner sleeve moves to the left, it drives the moving plate to move to the left. During the movement of the moving plate to the left, the rack is driven to move to the left through the moving seat. When the rack moves to the left, it drives the two adjacent second gears to rotate. When the two second gears rotate, the two retracting rollers are driven to rotate through the two rotating shafts, so that the left retracting roller outputs the strip sandpaper and the right retracting roller rewinds the strip sandpaper, so as to complete the switching of the contact position between the strip sandpaper and the base insulation layer enameled wire;

[0029] S4. During the switching process of the belt-shaped sandpaper, the rotating shaft drives the adjacent rotating disk to rotate continuously, and the rotating disk drives the multiple locking pins to rotate synchronously. During the rotation process, the locking pin moves out from the inner side of the current hemispherical groove and stretches the third spring. When the locking pin is collinear with the next hemispherical groove again, the stretched third spring drives the locking pin to be inserted into the inner side of the hemispherical groove again.

[0030] S5, when the outer sleeve moves to the left by a distance reaching the first threshold, the movable plate fits with the limit frame, and the strip sandpaper is switched. At the same time, due to the obstruction of the limit frame, the movable plate and the inner sleeve cannot continue to move to the left. Subsequently, as the outer sleeve continues to move to the left, the first spring is continuously compressed, and the outer sleeve continues to drive the push plate to move to the left through the outer sleeve plate;

[0031] S6, when the outer sleeve moves to the left by a distance reaching a second threshold, the left end of the push plate fits with the adjacent triangular prism, and as the push plate continues to move to the left, the push plate drives the moving seat to move outward through the triangular prism, and during the moving seat moving outward, the second spring is stretched, and the first annular magnet and the rack are driven to move outward synchronously, so as to release the meshing of the rack and the adjacent second gear;

[0032] S7, when the outer sleeve moves to the left by a distance reaching a third threshold, the first annular magnet is attracted to the adjacent second annular magnet, and the outer sleeve moves to the leftmost end of the reciprocating thread outside the hollow reciprocating screw. Subsequently, as the hollow reciprocating screw continues to rotate, the outer sleeve moves to the right and resets. During the rightward movement of the outer sleeve, the one-way switching mechanism is driven to move to the right synchronously. Since the rack is no longer meshed with the adjacent second gear at this time, the second gear does not rotate during the rightward movement of the rack;

[0033] S8, when the rightward movement distance of the outer sleeve reaches the fourth threshold, the outwardly moved triangular prism contacts the inclined surface of the adjacent trigger plate end, and as the triangular prism continues to move rightward, the trigger plate pushes the triangular prism, so that the triangular prism drives the moving seat to move inward, and during the inward movement of the moving seat, the first annular magnet is separated from the second annular magnet, and the rack is reset at the same time;

[0034] S9, when the outer sleeve moves rightwards to the fifth threshold, the outer sleeve reaches the rightmost end of the outer reciprocating thread of the hollow reciprocating screw, that is, the initial position. At this time, the multiple drive mechanism and the one-way switching mechanism are all reset, and then the drive motor is stopped.

[0035] Technical effects and advantages of the present invention:

[0036] The present invention is provided with a positioning mechanism, a multiple driving mechanism, a one-way switching mechanism, a switching grinding mechanism, an elastic locking mechanism and a limit trigger mechanism, so as to utilize four groups of switching grinding mechanisms to form cylindrical grinding sandpaper to complete the grinding of the base insulating layer enameled wire. In this process, the elastic locking mechanism locks the switching grinding mechanism to prevent the strip sandpaper from moving randomly. Later, during the grinding process or the non-grinding process, when part of the strip sandpaper in contact with the base insulating layer enameled wire needs to be replaced, the multiple driving mechanism drives the left side of the one-way switching mechanism, and then the one-way switching mechanism drives the adjacent switching grinding mechanism, thereby completing the strip sandpaper and the base insulating layer enameled wire. The contact position of the coated wire is switched, and then due to the obstruction of the limit trigger mechanism, the switching grinding mechanism cannot continue to move to the left, and at the same time the multiple driving mechanism triggers the one-way switching mechanism, so that the one-way switching mechanism is released from the engagement with the switching grinding mechanism, and then the multiple driving mechanism drives the one-way switching mechanism to move right and reset, until the one-way switching mechanism is triggered by the limit trigger mechanism to achieve recovery. Compared with the same type of device in the prior art, the present invention can more conveniently complete the switching of the contact position between the strip sandpaper and the base insulating layer enameled wire, is easy to operate, saves manpower and greatly reduces the difficulty of operation. In addition, switching can be achieved during the grinding process or the non-grinding process, and it is more flexible to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The present invention provides Figure 1-6The method for preparing a gold alloy self-adhesive enameled wire is used to manufacture the above-mentioned gold alloy self-adhesive enameled wire, and the method for preparing the gold alloy self-adhesive enameled wire is realized by a preparation device for the gold alloy self-adhesive enameled wire;

[0049] The preparation device of the gold alloy self-adhesive enameled wire comprises a shell 1, a positioning mechanism 2 is arranged at the left inner end of the shell 1, and a multiple driving mechanism 3 is arranged at the right inner end of the shell 1, a one-way switching mechanism 4 is connected to the left end of the multiple driving mechanism 3, four groups of switching grinding mechanisms 5 are evenly distributed on the outer side of the positioning mechanism 2, and two groups of elastic locking mechanisms 6 are arranged on any group of the switching grinding mechanisms 5, and a limited position trigger mechanism 7 is arranged on the left and right sides of the one-way switching mechanism 4;

[0050] The multiple driving mechanism 3 drives the one-way switching mechanism 4 to move left, thereby causing the one-way switching mechanism 4 to drive multiple groups of switching grinding mechanisms 5 to switch the contact position between the strip sandpaper 51 and the basic insulating layer. Subsequently, the limit trigger mechanism 7 blocks the one-way switching mechanism 4, and at the same time, the multiple driving mechanism 3 triggers the one-way switching mechanism 4, thereby causing the one-way switching mechanism 4 to no longer drive the switching grinding mechanism 5 during the resetting process. Finally, the limit trigger mechanism 7 triggers the one-way switching mechanism 4 to reset the limit trigger mechanism 7.

[0051] like Figure 2 As shown, the positioning mechanism 2 includes an arc-shaped positioning plate 21 and a fixed column 22, wherein the arc-shaped positioning plate 21 and the fixed column 22 are each provided with four, the four arc-shaped positioning plates 21 are distributed in a ring shape and closed to form a cylindrical shape, and the four fixed columns 22 are respectively fixedly arranged in the middle of the outer side of the four arc-shaped positioning plates 21 and are all fixedly connected to the inner wall of the outer shell 1.

[0053] like Figure 3As shown, the multi-drive mechanism 3 includes a mounting plate 31, a hollow reciprocating screw 32, a drive motor 33, a first gear 34, an outer sleeve 35, a first spring 36, an inner sleeve 37, an outer sleeve plate 38 and a push plate 39, wherein the mounting plate 31 is fixedly connected to the inner wall of the housing 1, the hollow reciprocating screw 32 passes through the mounting plate 31 and is rotatably connected to the mounting plate 31 through a bearing, the drive motor 33 is fixedly arranged on the right side of the mounting plate 31, two first gears 34 are provided, the two first gears 34 are meshed with each other, one of the first gears 34 is fixedly connected to the hollow reciprocating screw 32, and one of the first gears 34 is transmission-connected to the drive motor 33. The outer sleeve 35, the first spring 36 and the inner sleeve 37 are sequentially sleeved and arranged on the outside of the hollow reciprocating screw 32 from right to left. The outer sleeve 35 is transmission connected to the hollow reciprocating screw 32. The first spring 36 is fixedly connected between the first spring 36 and the inner sleeve 37. The inner sleeve 37 is slidingly connected to the hollow reciprocating screw 32 and is slidably arranged on the inner side of the outer sleeve 35. The outer sleeve plate 38 is fixedly sleeved and arranged on the left end of the outer side of the outer sleeve 35. Four push plates 39 are provided, and the four push plates 39 are evenly fixedly arranged on the left side of the outer sleeve plate 38. A guide rod is slidingly penetrated on the side of the mounting plate 31, and the guide rod is fixedly connected to the outer sleeve plate 38.

[0054] By setting the above structure, it is convenient to start the drive motor 33. After the drive motor 33 is started, the hollow reciprocating screw 32 is driven to rotate through the first gear 34. When the hollow reciprocating screw 32 rotates, it drives the outer sleeve 35 to move left. When the outer sleeve 35 moves left, the inner sleeve 37 is driven to move left through the first spring 36, and the push plate 39 is driven to move left through the outer plate 38.

[0055] like Figure 4 and Figure 5 As shown, the one-way switching mechanism 4 includes a moving plate 41, a mounting groove 42, a positioning column 43, a second spring 44, a moving seat 45, a first annular magnet 46, a second annular magnet 47, a rack 48 and a triangular prism 49, wherein the moving plate 41 is fixedly sleeved on the outer end of the inner sleeve 37, the mounting groove 42 is opened on the side of the moving plate 41, the positioning column 43 is fixedly set on the inner side of the mounting groove 42, the second spring 44, the moving seat 45, the first annular magnet 46 and the second annular magnet 47 are sequentially sleeved on the outer side of the positioning column 43 from the inside to the outside, the second spring 44 is fixedly connected between the inner wall of the mounting groove 42 and the moving seat 45, the moving seat 45 is slidably connected to the positioning column 43 and fixedly connected to the first annular magnet 46, the second annular magnet 47 is fixedly connected to the inner wall of the mounting groove 42, the rack 48 is fixedly set on the left end of the moving seat 45, and the triangular prism 49 is fixedly set on the right end of the moving seat 45.

[0056] By setting the above structure, when the inner sleeve 37 moves to the left, the moving plate 41 is driven to move to the left. During the movement of the moving plate 41 to the left, the rack 48 is driven to move to the left through the moving seat 45.

[0057] like Figure 2 As shown, the switchable grinding mechanism 5 includes a belt-shaped sandpaper 51 and two groups of retracting mechanisms, and any group of the retracting mechanisms includes a U-shaped frame 52, a rotating shaft 53, a retracting roller 54 and a second gear 55, wherein the belt-shaped sandpaper 51 bypasses the adjacent arc-shaped positioning plate 21 and its two ends are respectively fixedly connected to the two retracting rollers 54, the belt-shaped sandpaper 51 is wound around the outside of the left retracting roller 54, the U-shaped frame 52 is fixedly connected to the inner wall of the shell 1, the rotating shaft 53 is rotatably nested on the inner side of the belt-shaped sandpaper 51 through a bearing, the retracting roller 54 is fixedly sleeved in the middle of the outer side of the rotating shaft 53, and the second gear 55 is fixedly sleeved at one end of the outer side of the rotating shaft 53 and meshes with the adjacent rack 48.

[0058] By setting the above structure, when the rack 48 moves to the left, it drives the two adjacent second gears 55 to rotate. When the two second gears 55 rotate, the two retracting rollers 54 are driven to rotate through the two rotating shafts 53, so that the left retracting roller 54 outputs the strip sandpaper 51 and the right retracting roller 54 rewinds the strip sandpaper 51, so as to complete the switching of the contact position between the strip sandpaper 51 and the base insulating layer enameled wire.

[0059] like Figure 6 As shown, the elastic locking mechanism 6 includes a fixed disk 61, a hemispherical groove 62, a rotating disk 63, a locking pin 64 and a third spring 65, wherein the fixed disk 61 is sleeved on the outside of the adjacent rotating shaft 53 and fixedly connected to the adjacent U-shaped frame 52, the hemispherical groove 62 is opened on the side of the fixed disk 61 close to the rotating disk 63, the rotating disk 63 is fixedly sleeved on the outside of the adjacent rotating shaft 53, the locking pin 64 slides through the rotating disk 63, the end of the locking pin 64 is set to be hemispherical and slidably inserted into the inner side of the adjacent hemispherical groove 62, and the third spring 65 is sleeved on the outside of the locking pin 64 and fixedly connected between the rotating disk 63 and the locking pin 64.

[0060] By setting the above structure, during the grinding process, the locking pin 64 is inserted into the inner side of the adjacent hemispherical groove 62, thereby locking the rotating shaft 53 to prevent the rotating shaft 53 from rotating arbitrarily and causing the belt sandpaper 51 to switch. During the switching process of the belt sandpaper 51, the rotating shaft 53 drives the adjacent rotating disk 63 to rotate continuously. When the rotating disk 63 rotates, it drives multiple locking pins 64 to rotate synchronously. During the rotation of the locking pin 64, it moves out from the inner side of the current hemispherical groove 62 and stretches the third spring 65. When the locking pin 64 is collinear with the next hemispherical groove 62 again, the stretched third spring 65 drives the locking pin 64 to be inserted into the inner side of the hemispherical groove 62 again, thereby locking the belt sandpaper 51 again after the switching of the belt sandpaper 51 is completed.

[0062] By setting the above structure, when the movable plate 41 moves to the left, the limit frame 71 blocks the movable plate 41, thereby preventing the movable plate 41 from driving the rack 48 to move excessively to the left and causing the strip sandpaper 51 to be excessively switched. The trigger plate 72 can push the outward-moving triangular prism 49 during the rightward movement of the one-way switching mechanism 4, thereby causing the movable seat 45 to drive the first annular magnet 46 to disengage from the adjacent second annular magnet 47, and then the movable seat 45 is reset under the drive of the stretched second spring 44.

[0063] Example 3

[0064] The method specifically comprises the following steps:

[0065] S1. Put the basic insulating paint into the paint tank of the enameling wire machine, start the machine for wire running, and the gold alloy wire core passes through the paint tank and is heated and cured in a drying oven to obtain the basic insulating layer enameled wire;

[0066] The end of the base insulating layer enameled wire is passed through four arc-shaped positioning plates 21 and the hollow reciprocating screw 32, and then the end is connected to the winding device, so that the winding device continues to pull the base insulating layer enameled wire. During the pulling process, four arc-shaped strip sandpapers 51 formed under the action of the arc-shaped positioning plates 21 grind the outer surface of the base insulating layer enameled wire;

[0067] The self-adhesive insulating varnish is placed in the varnish tank of the next enameling wire machine, the machine is turned on for wiring, the polished base insulating layer enameled wire passes through the varnish tank and is heated and cured in a drying oven, and a certain degree of cross-linking reaction is performed to form a semi-cured self-adhesive insulating layer, that is, a gold alloy self-adhesive enameled wire is obtained;

[0068] S2. During the grinding process or the non-grinding process, when the part of the strip sandpaper 51 in contact with the base insulating layer enameled wire needs to be replaced, the drive motor 33 is started. After the drive motor 33 is started, the hollow reciprocating screw 32 is driven to rotate through the first gear 34. When the hollow reciprocating screw 32 rotates, the outer sleeve 35 is driven to move leftward. When the outer sleeve 35 moves leftward, the inner sleeve 37 is driven to move leftward through the first spring 36, and the push plate 39 is driven to move leftward through the outer sleeve plate 38;

[0069] S3, when the inner sleeve 37 moves to the left, it drives the moving plate 41 to move to the left. During the movement of the moving plate 41 to the left, the moving seat 45 drives the rack 48 to move to the left. When the rack 48 moves to the left, it drives the two adjacent second gears 55 to rotate. When the two second gears 55 rotate, the two retracting rollers 54 are driven to rotate through the two rotating shafts 53, so that the left retracting roller 54 outputs the strip sandpaper 51, and the right retracting roller 54 rewinds the strip sandpaper 51, so as to complete the switching of the contact position between the strip sandpaper 51 and the base insulation layer enameled wire;

[0070] S4. During the switching process of the belt-shaped sandpaper 51, the rotating shaft 53 drives the adjacent rotating disk 63 to rotate continuously. When the rotating disk 63 rotates, it drives the multiple locking pins 64 to rotate synchronously. During the rotation process, the locking pin 64 moves out from the inner side of the current hemispherical groove 62 and stretches the third spring 65. When the locking pin 64 is collinear with the next hemispherical groove 62 again, the stretched third spring 65 drives the locking pin 64 to be inserted into the inner side of the hemispherical groove 62 again.

[0071] S5, when the outer sleeve 35 moves to the left by a distance reaching the first threshold, the movable plate 41 is fitted with the limit frame 71, and the strip sandpaper 51 is switched. At the same time, due to the obstruction of the limit frame 71, the movable plate 41 and the inner sleeve 37 cannot continue to move to the left. Subsequently, as the outer sleeve 35 continues to move to the left, the first spring 36 is continuously compressed, and the outer sleeve 35 continues to drive the push plate 39 to move to the left through the outer sleeve plate 38;

[0072] S6, when the outer sleeve 35 moves to the left by a distance reaching a second threshold, the left end of the push plate 39 fits against the adjacent triangular prism 49, and as the push plate 39 continues to move to the left, the push plate 39 drives the moving seat 45 to move outward through the triangular prism 49, and the moving seat 45 stretches the second spring 44 during the outward movement, and at the same time drives the first annular magnet 46 and the rack 48 to move outward synchronously, so as to release the meshing of the rack 48 and the adjacent second gear 55;

[0073] S7, when the leftward movement distance of the outer sleeve 35 reaches the third threshold, the first annular magnet 46 is attracted by the adjacent second annular magnet 47, and the outer sleeve 35 moves to the leftmost end of the reciprocating thread outside the hollow reciprocating screw 32. Subsequently, as the hollow reciprocating screw 32 continues to rotate, the outer sleeve 35 moves rightward and resets. During the rightward movement of the outer sleeve 35, the one-way switching mechanism 4 is synchronously moved rightward. Since the rack 48 is no longer meshed with the adjacent second gear 55 at this time, the second gear 55 does not rotate during the rightward movement of the rack 48.

[0074] S8, when the rightward movement distance of the outer sleeve 35 reaches the fourth threshold, the outwardly moved triangular prism 49 contacts the inclined surface of the end of the adjacent trigger plate 72, and as the triangular prism 49 continues to move rightward, the trigger plate 72 pushes the triangular prism 49, so that the triangular prism 49 drives the moving seat 45 to move inward, and during the inward movement of the moving seat 45, the first annular magnet 46 and the second annular magnet 47 are disengaged, and the rack 48 is reset at the same time;

[0075] S9, when the rightward movement distance of the outer sleeve 35 reaches the fifth threshold, the outer sleeve 35 reaches the rightmost end of the outer reciprocating thread of the hollow reciprocating screw 32, that is, the initial position. At this time, the multiple driving mechanism 3 and the one-way switching mechanism 4 are all reset, and then the driving motor 33 is stopped.

During the grinding process or the non-grinding process, when part of the strip sandpaper in contact with the base insulating layer enameled wire needs to be replaced, the drive motor is started. After the drive motor is started, the hollow reciprocating screw is driven to rotate through the first gear. When the hollow reciprocating screw rotates, the outer sleeve is driven to move leftward.
