Abstract
Description
Technical Field
[0001] The utility model relates to the field of film-covered wire detection, in particular to a film-covered wire cutting detection mechanism. Background Art
[0002] The film-covered wire, also known as the Mylar wire, is a wire with one or more layers of Mylar film wrapped around the outside of the LITZ wire or enameled stranded wire. This increases the insulation voltage of the wire and also provides a shielding effect, and can replace the silk-covered wire.
[0003] The outer layer of the film-covered wire is wound with Mylar film. When cutting the film-covered wire, the cutter will squeeze the wire, and the stressed area will deform. It is easy for the Mylar film to be peeled off from the wire, resulting in the Mylar film at the cutting end edge not being able to continue to wrap around the wire and protruding outside the wire, which is not conducive to the subsequent processing and use of the film-covered wire. Content of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies in the prior art and propose a film-covered wire cutting detection mechanism.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A film-covered wire cutting detection mechanism includes a support mechanism, an upper detection mechanism is installed in the support mechanism, a lower detection mechanism is installed in the support mechanism, the upper detection mechanism is located above the lower detection mechanism, the upper detection mechanism includes a moving block, an installation hole is opened at the bottom of the moving block, a limiting ring is installed at the bottom of the installation hole, a moving rod is movably connected inside the installation hole, a flange is fixedly connected to the bottom of the moving rod, a connecting rod is fixedly connected to the lower surface of the flange, a first electrode plate is fixedly connected to the top of the moving rod, a third electrode plate is fixedly connected to the inner top of the installation hole, the first electrode plate is directly below the third electrode plate, a second electrode plate is fixedly connected to the bottom of the connecting rod, the lower detection mechanism includes a fixed block, a positioning hole is opened at the top of the fixed block, and a fourth electrode plate is fixedly connected inside the positioning hole, and the fourth electrode plate is directly below the second electrode plate.
[0006] As a further description of the above technical solution:
[0007] The support mechanism includes a frame, an electric push rod is fixedly connected to the inner top of the frame, the moving block is installed at the bottom of the electric push rod, and the fixed block is installed at the inner bottom of the frame.
[0008] As a further description of the above technical solution:
[0009] The flange is located above the limiting ring, and the outer diameter of the flange is greater than the inner diameter of the limiting ring.
[0010] As a further description of the above technical solution:
[0011] A limiting sleeve is fixedly connected to the upper surface of the limiting ring, and a clamping groove is formed on the inner surface of the limiting sleeve.
[0012] As a further description of the above technical solution:
[0013] A clamping block is fixedly connected to the outer surface of the moving rod, and the clamping block is located inside the clamping groove.
[0014] As a further description of the above technical solution:
[0015] A first indicator light is fixedly connected to the front surface of the moving block, and a first wire is fixedly connected to the back surface of the moving block.
[0016] As a further description of the above technical solution:
[0017] A second indicator light is fixedly connected to the front surface of the fixed block, and a second wire is fixedly connected to the back surface of the fixed block.
[0018] As a further description of the above technical solution:
[0019] A first groove is formed on the lower surface of the moving block, the first groove is of an arc structure, a second groove is formed on the upper surface of the fixed block, the second groove is of an arc structure, and the second groove is located directly below the first groove.
[0020] The utility model has the following beneficial effects:
[0021] 1. Compared with the prior art, for this film-covered wire cutting detection mechanism, through the upper detection mechanism and the lower detection mechanism, during use, the cut film-covered wire is moved between the first groove and the second groove by the device, and then the upper detection mechanism is controlled to move downward. When the upper detection mechanism moves downward, the moving rod and the connecting rod below will also move downward under the action of gravity. When the film-covered wire is cut normally, the height of the moving block drops, and the connecting rod also moves downward until the second electrode plate contacts the fourth electrode plate, and the circuit below will be connected to generate a current signal. At the same time, the second indicator light lights up. When the mylar film on the film-covered wire protrudes to the outside of the film-covered wire, the mylar film will block the connecting rod, making it unable to continue to descend, preventing the contact between the second electrode plate and the fourth electrode plate. And because the connecting rod cannot descend due to the blockage of the mylar film, the moving block continues to descend. At this time, the first electrode plate will contact the third electrode plate, and the circuit above will be connected to generate a current signal. At the same time, the first indicator light lights up. Thus, the cutting state of the film-covered wire can be automatically detected, and it can avoid the situation that when the cutter cuts, it will squeeze the film-covered wire, resulting in the mylar film at the cutting end edge not being able to continue to wrap around the film-covered wire, affecting the subsequent processing and use of the film-covered wire.
[0022] 2. Compared with the prior art, for the film-covered wire cutting detection mechanism, through the limiting ring, limiting sleeve, moving rod, and clamping block, when in use, the limiting sleeve on the limiting ring can limit the clamping block on the moving rod, so that the moving rod can only move up and down inside the limiting sleeve without rotating, ensuring that the positive and negative poles on the first electrode plate and the third electrode plate, and the second electrode plate and the fourth electrode plate always correspond to each other. This can prevent the moving column from rotating inside the mounting hole, avoiding the situation where the positive and negative poles on the electrode plate are misaligned.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0030] Refer to Figures 1-5, a film-covered wire cutting detection mechanism provided by the utility model: It includes a support mechanism 1, an upper detection mechanism 2 is installed inside the support mechanism 1, a lower detection mechanism 3 is installed inside the support mechanism 1, the upper detection mechanism 2 is located above the lower detection mechanism 3, and the upper detection mechanism 2 cooperates with the lower detection mechanism 3 to detect the cut film-covered wire. The upper detection mechanism 2 includes a moving block 201, an installation hole 202 is opened at the bottom of the moving block 201, a limiting ring 203 is installed at the bottom of the installation hole 202, a moving rod 206 is movably connected inside the installation hole 202, and the moving rod 206 can move up and down inside the installation hole 202. A flange 209 is fixedly connected to the bottom of the moving rod 206. Through the cooperation of the flange 209 and the limiting ring 203, the moving rod 206 can be restricted inside the installation hole 202. A connecting rod 210 is fixedly connected to the lower surface of the flange 209. A first electrode plate 208 is fixedly connected to the top of the moving rod 206. A third electrode plate 215 is fixedly connected to the inner top of the installation hole 202. When there is a protruding mylar film on the side of the film-covered wire, the first electrode plate 208 will contact the third electrode plate 215 to connect the upper circuit. The first electrode plate 208 is directly below the third electrode plate 215. A second electrode plate 211 is fixedly connected to the bottom of the connecting rod 210. The lower detection mechanism 3 includes a fixed block 301. A positioning hole 302 is opened at the top of the fixed block 301. A fourth electrode plate 303 is fixedly connected inside the positioning hole 302. The fourth electrode plate 303 is directly below the second electrode plate 211. Positive and negative connectors are provided on the first electrode plate 208, the second electrode plate 211, the third electrode plate 215 and the fourth electrode plate 303. When two electrode plates are in contact, the circuit will be connected. When the film-covered wire is cut normally, the second electrode plate 211 will contact the fourth electrode plate 303 to connect the lower circuit. During use, the cut film-covered wire is moved between the first groove 214 and the second groove 306 through a clamping device, and then the upper detection mechanism 2 is controlled to move downward. When the upper detection mechanism 2 moves downward, the lower moving rod 206 and the connecting rod 210 will also move downward together under the action of gravity. When the film-covered wire is cut normally, the height of the moving block 201 drops, and the connecting rod 210 also moves downward until the second electrode plate 211 contacts the fourth electrode plate 303, and the lower circuit will be connected to generate a current signal, and at the same time the second indicator light 304 lights up. When the mylar film on the film-covered wire protrudes to the outside of the film-covered wire, the mylar film will block the connecting rod 210, making it unable to continue to descend, preventing the second electrode plate 211 from contacting the fourth electrode plate 303. And because the connecting rod 210 cannot descend due to the block of the mylar film, the moving block 201 continues to descend. At this time, the first electrode plate 208 will contact the third electrode plate 215, and the upper circuit will be connected to generate a current signal, and at the same time the first indicator light 212 lights up. Thus, the cutting state of the film-covered wire can be automatically detected.
[0031] The support mechanism 1 includes a frame 101. An electric push rod 102 is fixedly connected to the inner top of the frame 101. A moving block 201 is installed at the bottom of the electric push rod 102. A fixed block 301 is installed at the inner bottom of the frame 101. The electric push rod 102 can control the downward movement of the moving block 201, facilitating the clamping and detection of the cut film-covered wire by the detection mechanism.
[0032] The flange 209 is located above the limiting ring 203, and the outer diameter of the flange 209 is greater than the inner diameter of the limiting ring 203, enabling the moving rod 206 to move up and down inside the mounting hole 202. A limiting sleeve 204 is fixedly connected to the upper surface of the limiting ring 203. A clamping groove 205 is formed on the inner surface of the limiting sleeve 204. A clamping block 207 is fixedly connected to the outer surface of the moving rod 206. The clamping block 207 is located inside the clamping groove 205, enabling the moving rod 206 to only move up and down inside the limiting sleeve 204 without rotation, so that the positive and negative poles on the first electrode plate 208 and the third electrode plate 215, and the second electrode plate 211 and the fourth electrode plate 303 always correspond to each other, avoiding the situation where the moving rod 206 rotates inside the mounting hole 202, resulting in the misalignment of the positive and negative poles on the electrode plates.
[0033] A first indicator light 212 is fixedly connected to the front of the moving block 201. A first wire 213 is fixedly connected to the back of the moving block 201. One end of the first wire 213 is connected to the third electrode plate 215. When the first electrode plate 208 contacts the third electrode plate 215, the circuit connected by the first wire 213 will be switched on, and at this time, the first indicator light 212 will emit light. A second indicator light 304 is fixedly connected to the front of the fixed block 301. A second wire 305 is fixedly connected to the back of the fixed block 301. One end of the second wire 305 is connected to the fourth electrode plate 303. When the second electrode plate 211 contacts the fourth electrode plate 303, the circuit connected by the second wire 305 will be switched on, and at this time, the second indicator light 304 will emit light.
[0034] A first groove 214 is formed on the lower surface of the moving block 201. The first groove 214 is an arc-shaped structure. A second groove 306 is formed on the upper surface of the fixed block 301. The second groove 306 is an arc-shaped structure. The second groove 306 is located directly below the first groove 214. During use, the cut film-covered wire is clamped by a clamping device and fed between the first groove 214 and the second groove 306, enabling the upper detection mechanism 2 and the lower detection mechanism 3 to detect the cut end of the film-covered wire.
[0035] Working principle: When in use, the cut film-covered wire is moved between the first groove 214 and the second groove 306 through a clamping device. Then, the upper detection mechanism 2 is controlled to move downward. When the upper detection mechanism 2 moves downward, the moving rod 206 and the connecting rod 210 below will also move downward under the action of gravity. When the film-covered wire is cut normally, the height of the moving block 201 decreases, and the connecting rod 210 also moves downward until the second electrode piece 211 contacts the fourth electrode piece 303, and the circuit below is connected to generate a current signal. At the same time, the second indicator light 304 lights up. When the mylar film on the film-covered wire protrudes to the outside of the film-covered wire, the mylar film will block the connecting rod 210, making it unable to continue to descend, preventing the contact between the second electrode piece 211 and the fourth electrode piece 303. And because the connecting rod 210 cannot descend due to the block of the mylar film, the moving block 201 continues to descend. At this time, the first electrode piece 208 will contact the third electrode piece 215, and the circuit above is connected to generate a current signal. At the same time, the first indicator light 212 lights up. Thus, the cutting state of the film-covered wire can be automatically detected.
