Description

TECHNICAL FIELD

[0001] The present application relates to the field of conductive bar production equipment, in particular to a device for detecting the deflection degree of a conductive bar. BACKGROUND

[0002] The conductive bar includes a conductive core and an insulating sheath, and the insulating sheath is arranged outside the conductive core, so that the conductive bar can transmit a large current through the conductive core. When producing the conductive bar, the conductive core needs to be pulled from a material roll through an extrusion die, and then the insulating sheath is formed outside the conductive core through the extrusion die.

[0003] In the prior art, the conductive core wound around the material roll usually has a large deformation when it is initially pulled away from the material roll, and needs to be corrected by extrusion and positioning of a plurality of correction rollers, so that the conductive core is accurately transported in the horizontal direction into the extrusion die, reducing the occurrence of elastic deformation of the conductive core after the formation of the insulating sheath, which causes the insulating sheath to have wrinkles or even cracks. In addition, the above content can also be combined with reference to the patent documents with publication numbers CN205004110U and CN117174399A.

[0004] In order to facilitate the detection of the transport direction of the conductive core within the design error, a photoelectric position sensor is usually arranged on both sides of the conductive core, and the emitter and receiver of the photoelectric position sensor are distributed in the vertical direction. When the conductive core is deflected in the horizontal direction, the conductive core is located between the emitter and the receiver, thereby switching the output signal of the photoelectric position sensor, and the processing system recognizes the conductive core after receiving the signal of the photoelectric position sensor, thereby informing the relevant technical personnel that the deflection degree of the conductive core has exceeded the design range and needs to be corrected in time.

[0005] In the prior art, the photoelectric position sensor is sensitive to the light conditions in the production workshop, which causes the photoelectric position sensor to have occasional false positives, thereby negatively affecting the judgment of the relevant technical personnel. SUMMARY

[0006] In order to reduce the adverse effects of light conditions on the detection of the deflection degree of the conductive bar, the present application provides a device for detecting the deflection degree of the conductive bar.

[0007] The device for detecting the deflection degree of the conductive bar provided by the present application adopts the following technical solution:

[0009] The vertical roller body is rotationally fitted to the detection rack, and the detection module is located at the bottom of the vertical roller body.

[0015] By adopting the above technical scheme, the vertical roller body is arranged close to the conductive inner core of the conductive row, so that the conductive inner core contacts the vertical roller body and drives the vertical roller body to rotate when the conductive inner core is deflected. When the vertical roller body rotates, the movable light transmission wheel is driven to rotate, so that the movable light transmission hole is in communication with the fixed light transmission hole, and then the light of the detection light source passes through the movable light transmission hole and the fixed light transmission hole to reach the receiving cavity. The luminosity sensor detects the change of the luminosity in the cavity, so as to detect whether the deflection degree of the conductive row exceeds the design requirement.

[0016] During the detection of the luminosity in the receiving cavity by the luminosity sensor, the light shielding shell isolates the ambient light from the receiving cavity, so that the light source in the receiving cavity is mainly limited to the detection light source, thereby reducing the interference of the ambient light, ensuring the detection accuracy of the luminosity sensor, and reducing the adverse effects of illumination conditions on the deflection degree detection of the conductive row.

[0022] The fixed light transmission holes are provided in plurality, and the fixed light transmission holes are respectively a first light transmission hole and a second light transmission hole, the first light transmission hole is communicated with the first receiving chamber, and the second light transmission hole is communicated with the second receiving chamber.

[0023] By adopting the technical scheme, when the first roller body is inclined under the action of the conductive inner core of the conductive row, the movable light transmission hole is driven to move towards the first light transmission hole, and then the movable light transmission hole is communicated with the first light transmission hole, so that the first sensor receives the light of the first light source, thereby detecting the inclination of the conductive row in one direction.

[0024] When the second roller body is inclined under the action of the conductive inner core of the conductive row, the movable light transmission hole is driven to move towards the second light transmission hole, and then the movable light transmission hole is communicated with the second light transmission hole, so that the second sensor receives the light of the second light source, thereby detecting the inclination of the conductive row in the other direction.

[0025] When the inclinations of the conductive row in two directions are detected, the light source partition plate and the receiving partition plate separate the light of the first light source and the second light source, so that the inclination detection in the two directions is not easy to interfere with each other, and the detection accuracy is improved.

[0026] Optionally, the light shielding shell is provided with a drive strip slide rail, the drive strip slide rail is slidably matched with a light transmission wheel drive strip, and the light transmission wheel drive strip is abuttingly matched with the movable light transmission wheel.

[0027] The light transmission wheel drive strip is installed on the vertical roller body through a hinged rod, and the two ends of the hinged rod are respectively rotationally matched with the vertical roller body and the light transmission wheel drive strip.

[0028] By adopting the technical scheme, when the first roller body or the second roller body rotates under the action of the deflection of the conductive inner core of the conductive row, the articulated rod is pulled or pushed, so that the articulated rod drives the light transmission wheel driving strip to move, thereby abutting against and driving the movable light transmission wheel to rotate.

The threads at the two ends of the bidirectional screw pipe are opposite in rotation direction.

[0032] By adopting the technical scheme, when the length of the articulated rod needs to be adjusted, the bidirectional screw pipe is rotated, and the first screw rod and the second screw rod move away from each other after moving close to each other, thereby changing the length of the articulated rod.

[0033] When the positions of the first roller body or the second roller body do not conform to the specifications of the conductive row and the production line, the first roller body or the second roller body is slid alone, and then the bidirectional screw pipe is rotated, so that the length of the articulated rod is adapted to the positions of the first roller body or the second roller body, thereby reducing the situation that the first roller body drives the second roller body to deflect or the second roller body drives the first roller body to deflect, and thereby ensuring the applicability and accuracy of the detection module.

[0035] By adopting the technical scheme, the driving strip flexible belt drives the movable light transmission wheel through friction, and thereby continuously drives the movable light transmission wheel to rotate, thereby reducing the situation that the movable light transmission wheel is stuck.

[0036] Optionally, the movable light transmission hole and the fixed light transmission hole extend circumferentially around the axis of the movable light transmission wheel.

[0037] By adopting the technical scheme, the luminosity in the receiving cavity is continuously changed according to the size of the region where the movable light transmission hole and the fixed light transmission hole overlap and communicate, so that the specific skew degree of the conductive row can be obtained through specific data of the luminosity, the situation of measurement and reciprocal adjustment of the technician is reduced, and the technician can be facilitated to adjust in time.

[0038] Optionally, the movable light transmission wheel is tightly matched with the fixed light transmission plate.

[0041] By adopting the technical scheme, the limiting rollers are respectively tightly matched with the vertical roller bodies from both sides, so that the vertical roller bodies are not easy to be skewed along the conveying direction of the conductive row.

The vertical roller body is arranged close to the conductive inner core of the conductive row, so that the conductive inner core is in contact with the vertical roller body and pushes the vertical roller body to rotate when the conductive inner core is skewed. When the vertical roller body rotates, the movable light transmission wheel is driven to rotate, so that the movable light transmission hole is communicated with the fixed light transmission hole, and then the light of the detection light source reaches the receiving cavity through the movable light transmission hole and the fixed light transmission hole. The luminosity sensor detects the change of the luminosity in the cavity, so as to detect whether the conductive row has a skew degree exceeding the design requirement;

[0044] During the detection of the luminosity in the receiving cavity by the luminosity sensor, the light shielding shell isolates the ambient light from the receiving cavity, so that the light source in the receiving cavity is mainly limited to the detection light source, thereby reducing the interference of the ambient light and ensuring the detection accuracy of the luminosity sensor, thereby reducing the adverse effects of illumination conditions on the detection of the skew degree of the conductive row.

DETAILED DESCRIPTION

[0053] The present application will be further described below in conjunction with the accompanying drawings. Figures 1-7 The present application will be further described below in conjunction with the accompanying drawings.

[0054] An apparatus for detecting the deflection of a conductive bar is disclosed in the embodiments of the present application. Referring to Figure 1 , the apparatus for detecting the deflection of a conductive bar comprises a detection rack 1, a vertical roller body 2, and a detection module.

[0055] Referring to Figure 1 , two sliding key grooves 101 are provided on the top of the detection rack 1, the two sliding key grooves 101 are distributed along the horizontal direction, and the two sliding key grooves 101 extend along the horizontal direction. The detection rack 1 is slidably fitted with two roller body sliding blocks 11 along the horizontal direction through the two sliding key grooves 101, and the positions of the two roller body sliding blocks 11 are locked by two bolts respectively threaded into the roller body sliding blocks 11 and penetrating through the sliding key grooves 101.

[0056] Referring to Figure 1 and Figure 2, two vertical roller bodies 2 are arranged, the two vertical roller bodies 2 are respectively arranged as a first roller body 201 and a second roller body 202, and the first roller body 201 and the second roller body 202 are distributed along the horizontal direction. The first roller body 201 and the second roller body 202 rotate around their respective rotating shafts, and the top of the rotating shaft of the first roller body 201 and the second roller body 202 is respectively rotationally connected to two roller sliding blocks 11. On the one hand, the first roller body 201 and the second roller body 202 rotate around the respective roller sliding blocks 11, and on the other hand, the first roller body 201 and the second roller body 202 slide through the respective roller sliding blocks 11 to adjust the distance between the first roller body 201 and the second roller body 202.

[0057] With reference to Figure 1 , a conductive row gap is formed between the first roller body 201 and the second roller body 202, and a conductive inner core of the conductive row is arranged in the conductive row gap. During the arrangement of the conductive inner core in the conductive row gap, the conductive inner core rubs against the first roller body 201 and / or the second roller body 202, causing the first roller body 201 and / or the second roller body 202 to rotate, thereby reducing the wear of the conductive inner core. When the deflection of the conductive inner core is within the design range, the first roller body 201 and the second roller body 202 will remain vertical under the action of gravity. When the deflection of the conductive inner core exceeds the design range, the conductive inner core abuts against the first roller body 201 or the second roller body 202 from the conductive row gap and pushes the first roller body 201 or the second roller body 202, causing the first roller body 201 or the second roller body 202 to deviate from the vertical state and deflect. Therefore, the device for detecting the deflection of the conductive row in the embodiment converts the deflection signal of the conductive inner core into the mechanical deflection signal of the first roller body 201 and the second roller body 202, thereby reducing the adverse effects of the environmental light source.

[0058] With reference to Figure 1 , the detection rack 1 is rotationally connected to four limiting rollers 12, and the four limiting rollers 12 are divided into two groups. The two groups of limiting rollers 12 are respectively located at the top and the bottom of the vertical roller body 2. The two limiting rollers 12 in the same group are distributed along the conveying direction of the conductive inner core, and the two limiting rollers 12 are respectively abutted and connected to the vertical roller body 2 from both sides. Thus, the vertical roller body 2 is less likely to deflect along the conveying direction of the conductive inner core, thereby improving the deflection signal accuracy of the vertical roller body 2.

[0059] With reference to Figure 3 , the detection module includes a light shielding shell 3, and a sliding rail mounting groove is formed in the top of the light shielding shell 3. A driving strip sliding rail 31 is mounted in the sliding rail mounting groove by bolts, and a light transmission wheel driving strip 32 is slidingly connected to the driving strip sliding rail 31 along the horizontal direction.

[0060] The light transmission wheel driving strip 32 comprises a driving strip slider 321 and a driving strip flexible band 322. The driving strip slider 321 is slidingly fitted in the driving strip sliding groove, and the driving strip flexible band 322 is fixedly installed at the bottom of the driving strip slider 321. The driving strip flexible band 322 is flexible, and in the embodiment, the material of the driving strip flexible band 322 is silica gel, so that the driving strip flexible band 322 can closely fit other components.

[0061] With reference to Figure 1 and Figure 4 The light transmission wheel driving strip 32 is installed on each vertical roller body 2 through two hinged rods, which comprise a first screw rod 21, a second screw rod 22 and a double-way screw pipe 23. The top end of the first screw rod 21 is rotationally fitted in the vertical roller body 2, and the bottom end of the first screw rod 21 is threadedly fitted in the top end of the double-way screw pipe 23. The bottom end of the second screw rod 22 is rotationally fitted in the light transmission wheel driving strip 32, and the top end of the second screw rod 22 is threadedly fitted in the bottom end of the double-way screw pipe 23. The threads of the top end and the bottom end of the double-way screw pipe 23 are in opposite directions, so that the length of the vertical roller body 2 can be changed by rotating the double-way screw pipe 23, so that when the deflection of the conductive inner core is within the design error range, the first roller body 201 and the second roller body 202 can be stably kept in the vertical state under the action of gravity, and the shaking of the first roller body 201 or the second roller body 202 can be reduced.

[0062] With reference to Figure 5 and Figure 6 The inside of the light shielding shell 3 is provided with a detection chamber, which is closed to prevent ambient light from entering the detection chamber through the light shielding shell 3, so that the inside of the detection chamber is not easily disturbed by ambient light.

[0063] The detection module further comprises a fixed light transmission plate 4, a movable light transmission wheel 5, a detection light source 6 and a photometric sensor 7. The movable light transmission wheel 5, the fixed light transmission plate 4, the detection light source 6 and the photometric sensor 7 are all located inside the detection chamber, so that the movable light transmission wheel 5, the fixed light transmission plate 4, the detection light source 6 and the photometric sensor 7 have relatively stable light conditions when working.

[0064] With reference to Figure 5 and Figure 6The fixed light-transmitting plate 4 separates the detection chamber into a light source cavity and a receiving cavity, thereby limiting the propagation of light between the light source cavity and the receiving cavity. The light-blocking shell 3 is fixedly provided with a light source partition plate 33, the light source partition plate 33 is located in the light source cavity, and the light source partition plate 33 is arranged in the shape of a cross. One side of the movable light-transmitting wheel 5 is rotatably connected to the light source partition plate 33, so that the movable light-transmitting wheel 5 rotates relative to the light-blocking shell 3 through the light source partition plate 33. The other side of the movable light-transmitting wheel 5 is tightly connected to one side of the fixed light-transmitting plate 4, so that light is not easily leaked out of the gap between the movable light-transmitting wheel 5 and the fixed light-transmitting plate 4. The top of the movable light-transmitting wheel 5 is abuttingly connected to the bottom of the driving strip flexible belt 322, so as to drive the driving strip flexible belt 322 to rotate the movable light-transmitting wheel 5 through the friction between the driving strip flexible belt 322 and the movable light-transmitting wheel 5. The light-blocking shell 3 is also fixedly provided with a receiving partition plate 34, the receiving partition plate 34 is located in the receiving cavity, and the receiving partition plate 34 is arranged in the shape of a T. The receiving partition plate 34 is tightly connected to the other side of the fixed light-transmitting plate 4, so that light is not easily leaked out of the gap between the receiving partition plate 34 and the fixed light-transmitting plate 4.

[0065] The light source partition plate 33 separates the light source cavity into a first light-emitting chamber 301 and a second light-emitting chamber 302, and the first light-emitting chamber 301 and the second light-emitting chamber 302 are both located at the top of the light source partition plate 33, and the propagation of light between the first light-emitting chamber 301 and the second light-emitting chamber 302 is hindered by the light source partition plate 33. The receiving partition plate 34 separates the receiving cavity into a first receiving chamber 303 and a second receiving chamber 304, and the first receiving chamber 303 and the second receiving chamber 304 are both located at the top of the receiving partition plate 34, and the propagation of light between the first receiving chamber 303 and the second receiving chamber 304 is hindered by the receiving partition plate 34. In addition, in the embodiment of the present application, the first receiving chamber 303 is correspondingly arranged with the first light-emitting chamber 301, and the second receiving chamber 304 is correspondingly arranged with the second light-emitting chamber 302.

[0066] The detection light source 6 is provided with two, and the two detection light sources 6 are respectively arranged as a first light source and a second light source. The first light source and the second light source are both fixedly installed on the light-blocking shell 3, and the first light source and the second light source are respectively located in the first light-emitting chamber 301 and the second light-emitting chamber 302. The light intensity sensor 7 is used for detecting the light intensity in the receiving cavity, and the light intensity sensor 7 is connected to an external detection system (not shown in the figure), and the detection system is used for outputting the deflection degree mapped by the light intensity sensor 7. The light intensity sensor 7 is provided with two, and the two light intensity sensors 7 are respectively arranged as a first sensor and a second sensor, and the first sensor and the second sensor are both fixedly installed on the light-blocking shell 3, and the first sensor and the second sensor are respectively located in the first receiving chamber 303 and the second receiving chamber 304.

[0067] The fixed light transmission plate 4 is provided with two fixed light transmission holes, which are respectively a first light transmission hole 401 and a second light transmission hole 402. The first light transmission hole 401 and the second light transmission hole 402 are located at the top of the fixed light transmission plate 4, and the first light transmission hole 401 and the second light transmission hole 402 are respectively communicated with the first receiving chamber 303 and the second receiving chamber 304, and the first light transmission hole 401 and the second light transmission hole 402 extend circumferentially around the axis of the movable light transmission wheel 5. The movable light transmission wheel 5 is provided with two movable light transmission holes 501, and the two movable light transmission holes 501 extend circumferentially around the axis of the movable light transmission wheel 5. The two movable light transmission holes 501 are respectively arranged corresponding to the first light transmission hole 401 and the second light transmission hole 402, and the two movable light transmission holes 501 are communicated or blocked with the first light transmission hole 401 or the second light transmission hole 402 through the rotation of the movable light transmission wheel 5, and then the light intensity in the first receiving chamber 303 or the second receiving chamber 304 is continuously changed through the on-off of the first light transmission hole 401 or the second light transmission hole 402, so that the first sensor or the second sensor outputs the corresponding light intensity value.

[0068] The implementation principle of the device for detecting the deflection of the conductive row in the embodiment of the application is that when the deflection of the conductive inner core is too large, the conductive inner core will abut against one of the vertical roller bodies 2, and then push the vertical roller body 2 originally in the vertical state to swing.

[0069] In combination Figure 7 When the vertical roller body 2 swings, the light transmission wheel driving strip 32 is driven to move horizontally along the Arrow-X direction through the hinged rod, and then the movable light transmission wheel 5 is driven to rotate along the Arrow-Y direction through the friction force, and then part or the whole of one of the movable light transmission holes 501 is overlapped and communicated with the fixed light transmission hole, so as to change the light intensity in the first receiving chamber 303 or the second receiving chamber 304. The first detector detects the light intensity in the first receiving chamber 303, or the second detector detects the light intensity in the second receiving chamber 304, and then the size of the deflection of one side of the conductive inner core is judged according to the light intensity detected by the first detector and the second detector.

[0070] In the process that the first sensor and the second sensor detect the light intensity in the receiving cavity, the light shielding shell 3 isolates the ambient light from the receiving cavity, so that the light sources of the first receiving chamber 303 and the second receiving chamber 304 are mainly limited to the first light source and the second light source respectively, thereby reducing the interference of the ambient light, ensuring the detection accuracy of the light intensity sensor 7, and reducing the adverse effect of the illumination condition on the detection of the deflection of the conductive row

[0071] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, so that: any equivalent changes made on the structure, shape and principle of the application should be covered in the protection scope of the application.
