Description

Technical Field

[0001] This invention relates to the technical field of varnish removal devices for enamel-coated wires, specifically a mechanism for removing the insulation layer from coil lead ends. Background Technology

[0002] A coil usually refers to a loop of wire winding. The most common applications of coils include motors, inductors, transformers, and loop antennas. In a circuit, a coil refers to an inductor, which is a coil of wires wound together, with the wires insulated from each other. The insulating tube can be hollow or contain an iron core or a magnetic powder core. Inductors can be divided into fixed inductors and variable inductors. Fixed inductor coils are simply called inductors or coils.

[0003] Before leaving the factory, the coil needs to undergo secondary processing, which involves removing the insulation from the wire ends. There are many existing methods for removing insulation varnish, but laser removal is too expensive, and manual removal with a knife is time-consuming and damages the wires, and it cannot remove the insulation from two varnished wires at the same time. Therefore, it is necessary to invent a mechanism for removing the insulation layer from the coil wire ends to solve the above problems. Summary of the Invention

A limit mechanism is fixedly mounted on the outer wall of the insulation removal mechanism. The insulation removal mechanism includes an outer shell, a centrifugal block installed on the inner wall of the outer shell, a connecting block installed on the top of the centrifugal block, a passive block movably connected to the end of the connecting block away from the centrifugal block, a roller installed at the bottom of the passive block, a removal rod provided at the bottom of the roller, and a removal knife fixedly assembled at the end of the removal rod away from the outer shell. The above structure is provided in three sets, and an installation groove is opened on the outer wall of the outer shell. The centrifugal block is equipped with a centrifugal top rod and a centrifugal bottom rod at its top and bottom, respectively. The connecting block is movably connected to the centrifugal top rod. Centrifugal top rings are movably sleeved at both ends of the centrifugal top rod, and centrifugal bottom rings are movably sleeved at both ends of the centrifugal bottom rod. A top limiting groove is provided on the inner wall of the outer shell, and a bottom limiting groove is provided at the bottom of the top limiting groove. The centrifugal top ring and the centrifugal bottom ring are slidably connected to the top limiting groove and the bottom limiting groove, respectively. The passive block is equipped with a passive top rod and a passive bottom rod at its top and bottom, respectively. The connecting block is movably connected to the passive top rod. A passive top ring is movably sleeved at both ends of the passive top rod, and a passive bottom ring is movably sleeved at both ends of the passive bottom rod. The passive top ring and the passive bottom ring are slidably connected to the top limiting groove and the bottom limiting groove, respectively. The connecting block is mounted on the outer casing via a top connecting rod, the connecting block is movably connected to the top connecting rod, and the top connecting rod is fixedly mounted on the outer casing; The removal rod is mounted on the outer casing via a bottom connecting rod, and the removal rod is movably connected to the bottom connecting rod, which is located at the center of the bottom of the centrifugal block and the passive block.

[0007] As a preferred embodiment of the present invention, the limiting mechanism includes a movable rod, a roller is installed at the bottom of the movable rod, a rotating bolt is movably sleeved on the inner wall of the movable rod, the rotating bolt is threadedly connected to the outer shell, and a rotating cover is fixedly assembled at the end of the rotating bolt away from the roller.

[0008] As a preferred embodiment of the present invention, the bottom of the rotating cover is provided with a contact base, and a support spring is provided between the contact base and the rotating cover.

[0009] As a preferred embodiment of the present invention, a sleeve is movably sleeved on the inner wall of the supporting spring, the sleeve is fixedly mounted on the rotating cover, and a sliding rod is slidably connected to the inner wall of the sleeve, the sliding rod being fixedly mounted on the contact base.

[0010] As a preferred embodiment of the present invention, the outer wall of the contact base is provided with scale lines, and the outer wall of the outer shell is fixedly fitted with an observation strip, which corresponds to the scale lines.

[0011] As a preferred embodiment of the present invention, a top damping rubber ring is fixedly mounted on the bottom of the contact base, and a bottom damping rubber ring is provided at the bottom of the top damping rubber ring, and the bottom damping rubber ring is fixedly mounted in the mounting groove.

[0012] The present invention has the following beneficial effects: 1. The coil lead-out insulation removal mechanism uses centrifugal force to throw the centrifugal block to the outside of the outer shell. The movement of the centrifugal block causes the connecting block to move on the top limiting groove. The end of the passive top ring away from the centrifugal block will move downward. At this time, the passive block is pushed downward by the connecting block. The force of the passive block being moved by the connecting block and the roller pushes the removal rod towards the middle, so that the removal blade at the head of the removal rod damages the insulating varnish. By pulling the coil backward at a uniform speed, the rotating removal blade can remove the insulating varnish on the enamel wire, effectively solving the problems of high cost of using laser and time-consuming and wire-damaging manual use of small knives.

[0013] 2. The insulation removal mechanism at the coil lead end features three limiting mechanisms. Three rollers contact the enamel-coated wire, and the movement of the enamel-coated wire drives the rollers. The rollers prevent damage to the enamel-coated wire during movement. Simultaneously, the three rollers straighten the enamel-coated wire from a bent state and position it at the center of the three removal blades, effectively improving the removal effect of the insulating varnish on the surface of the enamel-coated wire.

[0014] 3. The coil lead-out insulation layer removal mechanism uses the friction between the top and bottom damping rubber rings, along with the elasticity of the support spring, to tightly fit the top and bottom damping rubber rings together. This increases the rotational force between the top and bottom damping rubber rings, preventing the rotating cover from rotating when the outer shell rotates, thus improving the stability of the limiting mechanism.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1 - Figure 8 A coil lead wire insulation removal mechanism includes a mounting housing 1, a drive motor 2 is fixedly mounted on the outer wall of the mounting housing 1, a drive gear 3 is fixedly sleeved on the power output shaft of the drive motor 2, a driven gear 4 and a driven gear 5 are meshed on the outer edge of the drive gear 3, and a left removal component 6 and a right removal component 7 with the same structure are fixedly sleeved on the inner walls of the driven gear 4 and the driven gear 5 respectively. In the above structure, the drive motor 2 drives the drive gear 3 to rotate, and the rotation of the drive gear 3 drives the driven gear 4 and the driven gear 5 to rotate. The left removal component 6 and the right removal component 7 installed on the driven gear 4 and the driven gear 5 can rotate, and the insulating varnish on the enamel-coated wire is removed by the rotation of the left removal component 6 and the right removal component 7.

[0019] The left-side removal component 6 includes a hollow connecting rod 61. An insulation removal mechanism 62 is fixedly mounted on the end of the hollow connecting rod 61 away from the driven gear 4. A limit mechanism 63 is fixedly mounted on the outer wall of the insulation removal mechanism 62. In the above structure, the insulation removal mechanism 62 is the main structure for removing the insulating varnish, and the limiting mechanism 63 can change the varnished wire from a bent state to a straight state, so that the insulation removal mechanism 62 can fully remove the insulating varnish on the varnished wire and improve the insulation varnish removal efficiency.

[0020] The insulation removal mechanism 62 includes an outer shell 6201. A centrifugal block 6202 is installed on the inner wall of the outer shell 6201. A connecting block 6203 is installed on the top of the centrifugal block 6202. A passive block 6204 is movably connected to the end of the connecting block 6203 away from the centrifugal block 6202. A roller 6205 is installed at the bottom of the passive block 6204. A removal rod 6214 is provided at the bottom of the roller 6205. A removal knife 6215 is fixedly assembled at the end of the removal rod 6214 away from the outer shell 6201. The above structure is provided in three sets. An installation groove 6220 is opened on the outer wall of the outer shell 6201.

[0021] In the above structure, the centrifugal block 6202, the connecting block 6203 and the passive block 6204 are arranged so that centrifugal force is generated when the equipment rotates. At this time, the centrifugal block 6202 will be thrown to the outside. The movement of the centrifugal block 6202 will drive the connecting block 6203 to rotate. The rotation of the connecting block 6203 will drive the passive block 6204 to move downward. The force of the passive block 6204 moving downward will push the removal rod 6214 and the removal knife 6215 towards the middle, so that the removal knife 6215 rotates to remove the insulating varnish.

[0022] Centrifugal top rod 6206 and centrifugal bottom rod 6208 are respectively installed on the top and bottom of centrifugal block 6202. Connecting block 6203 is movably connected to centrifugal top rod 6206. Centrifugal top ring 6207 is movably sleeved at both ends of centrifugal top rod 6206. Centrifugal bottom ring 6209 is movably sleeved at both ends of centrifugal bottom rod 6208. A top limiting groove 6216 is opened on the inner wall of outer shell 6201. A bottom limiting groove 6217 is provided at the bottom of the top limiting groove 6216. Centrifugal top ring 6207 and centrifugal bottom ring 6209 are slidably connected to the top limiting groove 6216 and the bottom limiting groove 6217 respectively. In the above structure, the centrifugal top ring 6207 and centrifugal bottom ring 6209 are configured to cooperate with the top limiting groove 6216 and the bottom limiting groove 6217, so that the centrifugal block 6202 can be moved vertically to the upper right, which can prevent the centrifugal block 6202 from shaking in the outer shell 6201 and improve the stability of the device.

[0023] The passive block 6204 is equipped with a passive top rod 6212 and a passive bottom rod 6210 at its top and bottom, respectively. The connecting block 6203 is movably connected to the passive top rod 6212. The passive top rod 6212 is movably sleeved with a passive top ring 6213 at both ends. The passive bottom rod 6210 is movably sleeved with a passive bottom ring 6211 at both ends. The passive top ring 6213 and the passive bottom ring 6211 are slidably connected to the top limiting groove 6216 and the bottom limiting groove 6217. In the above structure, by setting the passive top ring 6213 and the passive bottom ring 6211, the connecting block 6203 will drive the passive block 6204 to move when it rotates. At this time, the passive block 6204 moves along the trajectory of the top limiting groove 6216 and the bottom limiting groove 6217. The passive top ring 6213 and the passive bottom ring 6211 move in the top limiting groove 6216 and the bottom limiting groove 6217, so that the passive block 6204 moves vertically to the lower left, and gradually the roller 6205 on the passive block 6204 comes into contact with the removal rod 6214, so that the removal rod 6214 can change angle.

[0024] The connecting block 6203 is mounted on the outer shell 6201 via the top connecting rod 6218. The connecting block 6203 is movably connected to the top connecting rod 6218, and the top connecting rod 6218 is fixedly mounted on the outer shell 6201. In the above structure, the top connecting rod 6218 can fix the connecting block 6203, so that the connecting block 6203 can only rotate on the top connecting rod 6218. When the centrifugal block 6202 moves upward, it can push the connecting block 6203 to rotate on the top connecting rod 6218, so that the end of the connecting block 6203 away from the centrifugal block 6202 moves downward. Therefore, the passive block 6204 can be displaced downward, which improves the rationality of the device.

[0025] The removal rod 6214 is mounted on the outer casing 6201 via the bottom connecting rod 6219. The removal rod 6214 is movably connected to the bottom connecting rod 6219, which is located at the center of the bottom of the centrifugal block 6202 and the passive block 6204. In the above structure, the bottom connecting rod 6219 limits the removal rod 6214, allowing the removal rod 6214 to rotate only on the bottom connecting rod 6219. The bottom connecting rod 6219 is positioned at the center of the bottom of the centrifugal block 6202 and the passive block 6204, so that the bottom connecting rod 6219 is located behind the contact point between the roller 6205 and the removal rod 6214. When the roller 6205 moves downward, the end of the removal rod 6214 away from the bottom connecting rod 6219 can move downward and contact the coating line, improving the rationality of the device.

[0026] In a preferred embodiment: the limiting mechanism 63 includes a moving rod 6301, a roller 6302 is installed at the bottom of the moving rod 6301, a rotating bolt 6303 is movably sleeved on the inner wall of the moving rod 6301, the rotating bolt 6303 is threadedly connected to the outer shell 6201, and a rotating cover 6304 is fixedly assembled at the end of the rotating bolt 6303 away from the roller 6302. In the above structure, through the setting of rollers 6302, when the enamel-coated wire is moving, the three rollers 6302 on the device will come into contact with the enamel-coated wire. When the enamel-coated wire moves, it will drive the rollers 6302 to move as well. The rollers 6302 can prevent the enamel-coated wire from being damaged during movement. At the same time, the three rollers 6302 can also straighten the bent enamel-coated wire and position the enamel-coated wire so that it is located at the center of the three removal blades 6215, which can effectively improve the removal effect of the insulating varnish on the surface of the enamel-coated wire.

[0027] In a preferred embodiment: the bottom of the rotating cover 6304 is provided with a contact base 6308, and a support spring 6307 is provided between the contact base 6308 and the rotating cover 6304; In the above structure, the support spring 6307 can support the contact base 6308 and the top damping rubber ring 6310, so that the contact base 6308 and the top damping rubber ring 6310 are always in contact with the surface of the outer shell 6201, making it easy for the user to observe the position of the contact base 6308 and the observation strip 6312, and making it easy for the user to quickly locate the position of the roller 6302.

[0028] In a preferred embodiment: a sleeve 6305 is movably sleeved on the inner wall of the support spring 6307, the sleeve 6305 is fixedly mounted on the rotating cover 6304, and a slide rod 6306 is slidably connected to the inner wall of the sleeve 6305, the slide rod 6306 is fixedly mounted on the contact base 6308. In the above structure, the sleeve 6305 and the slide rod 6306 can limit the support spring 6307, preventing it from detaching from the rotating cover 6304 and the contact base 6308, thus improving the stability of the device. The sliding connection between the sleeve 6305 and the slide rod 6306 is also for limiting the support spring 6307 when the rotating bolt 6303 is rotating, further improving the stability of the device.

[0029] In a preferred embodiment: the outer wall of the contact base 6308 is provided with a scale line 6309, and the outer wall of the outer shell 6201 is fixedly fitted with an observation strip 6312, which corresponds to the scale line 6309. In the above structure, the rotating cover 6304 rotates when it rotates, which drives the contact base 6308 to rotate as well as the observation strip 6312. The observation strip 6312 is fixed on the outer shell 6201, so it remains stationary. The position of the roller 6302 can be determined by reading the data between the observation strip 6312 and the scale line 6309. Since the diameter of the enameled line is small, the rotating cover 6304 and the rotating bolt 6303 do not need to rotate significantly.

[0030] In a preferred embodiment: a top damping rubber ring 6310 is fixedly mounted on the bottom of the contact base 6308, and a bottom damping rubber ring 6311 is provided at the bottom of the top damping rubber ring 6310. The bottom damping rubber ring 6311 is fixedly mounted in the mounting groove 6220. In the above structure, the top damping rubber ring 6310 and the bottom damping rubber ring 6311 work together. Since the top damping rubber ring 6310 and the bottom damping rubber ring 6311 are made of rubber, there is a large friction between them. The elastic force of the support spring 6307 keeps the top damping rubber ring 6310 and the bottom damping rubber ring 6311 tightly attached, so that the rotating cover 6304 will not rotate when the outer shell 6201 rotates, thus improving the stability of the device.

[0031] Working principle: During use, the coil wire end to be processed is inserted into the inner cavity of the left removal component 6 and the right removal component 7. Rotating the rotating cover 6304 causes the rotating bolt 6303 to rotate, which in turn moves the moving rod 6301 and the roller 6302. The moving rod 6301 slides on the outer shell 6201, causing the roller 6302 to move towards the center and contact the enameled wire. As the rotating cover 6304 rotates, it drives the contact base 6308 to rotate. The rotation of the rotating cover 6304 is stopped by observing the positional relationship between the scale line 6309 and the observation bar 6312 on the contact base 6308. Then, the setting is activated, and the drive motor 2 drives the drive gear 3 to rotate. The drive gear 3 rotates the driven gear 4 and driven gear 5, which in turn rotate the left removal component 6 and the right removal component 7. During rotation, centrifugal force causes the wire to... Centrifugal block 6202 is thrown to the outside of outer shell 6201. At this time, the movement of centrifugal block 6202 will cause connecting block 6203 to rotate on top connecting rod 6218. The end of passive top ring 6213 away from centrifugal block 6202 will move downward. At this time, passive block 6204 is pushed downward by connecting block 6203, gradually making roller 6205 on passive block 6204 come into contact with removal rod 6214. The force of roller 6205 pushing removal rod 6214 towards the middle is then applied. The coil is pulled backward at a constant speed, causing the removing blade 6215 at the head of the removing rod 6214 to break the insulating varnish. The rotating removing blade 6215 can remove the insulating varnish from the enamel-coated wire. When the coil is pulled, the three rollers 6302 clamp and position the enamel-coated wire, and the rollers 6302 are in front of the removing blade 6215. At this time, the bent enamel-coated wire has been straightened by the three rollers 6302, so that the insulating varnish on the surface of the enamel-coated wire can be effectively removed.
