Description

Technical Field

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

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

[0003] In the existing related technologies, the conductive inner 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 squeezing and limiting several correction rollers, so that the conductive inner core is accurately transported to the extrusion die in the horizontal direction, and the conductive inner core is prevented from elastically deforming after the insulating outer skin is formed, resulting in wrinkles or even cracks in the insulating outer skin. 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 whether the conveying direction of the conductive core is within the design error, photoelectric position sensors are usually set 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 deflects in the horizontal direction, the conductive core is located between the emitter and the receiver, and then the output signal of the photoelectric position sensor is switched. After the processing system receives the signal of the photoelectric position sensor, it identifies the conductive core, thereby informing the relevant technicians that the deflection of the wire core has exceeded the design range and needs to be calibrated in time.

[0005] Regarding the above-mentioned related technologies, during actual use, the applicant found that the photoelectric position sensor is sensitive to the lighting conditions in the production workshop, which causes the photoelectric position sensor to occasionally give false alarms, resulting in a negative impact on the judgment of relevant technical personnel. Summary of the invention

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

[0007] The present application provides a device for detecting the deflection of a conductive bar using the following technical solution: A device for detecting the deflection of a conductive bar, comprising a detection frame, a vertical roller body and a detection module; The vertical roller body is rotatably matched with the detection frame, and the detection module is located at the bottom of the vertical roller body; The detection module comprises a light-shielding housing, a movable light-transmitting wheel, a fixed light-transmitting plate, a detection light source and a photometric sensor; A detection chamber is provided inside the light-shielding shell, and the light-shielding shell is used to block ambient light from entering the detection chamber. The fixed light-transmitting plate, the movable light-transmitting wheel, the detection light source and the photometric sensor are all located in the detection chamber; The movable light-transmitting wheel is rotatably matched with the light-shielding housing, and the movable light-transmitting wheel is movably matched with the vertical roller body, and the rotation of the movable light-transmitting wheel is driven by the rotation of the vertical roller body; The fixed light-transmitting plate is installed on the light-shielding housing, the fixed light-transmitting plate is penetrated with a fixed light-transmitting hole, the movable light-transmitting wheel is penetrated with a movable light-transmitting hole, and the movable light-transmitting hole is connected or separated with the fixed light-transmitting hole through the rotation of the movable light-transmitting wheel; The fixed light-transmitting plate divides the detection chamber into a light source chamber and a receiving chamber. The detection light source is located in the light source chamber, and the photometric sensor is located in the receiving chamber. The photometric sensor is used to detect the light intensity in the receiving chamber.

[0008] By adopting the above technical solution, the vertical roller is arranged close to the conductive inner core of the conductive row, so that the conductive inner core contacts the vertical roller when deflected and drives the vertical roller to rotate. When the vertical roller rotates, it drives the movable light-transmitting wheel to rotate, so that the movable light-transmitting hole is connected to the fixed light-transmitting hole, and then the light of the detection light source passes through the movable light-transmitting hole and the fixed light-transmitting hole to reach the receiving cavity. The photometric sensor detects the light intensity change in the cavity, thereby detecting whether the conductive row has a deflection that exceeds the design requirements.

[0009] During the process of the photometric sensor detecting the light intensity in the receiving cavity, the light-shielding housing 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 ambient light, ensuring the detection accuracy of the photometric sensor, and reducing the adverse effects of lighting conditions on the detection of the deflection of the conductive bar.

[0010] Optionally, the vertical roller bodies are provided with a plurality of them, and the plurality of the vertical roller bodies are respectively provided with a first roller body and a second roller body, the first roller body and the second roller body are distributed in a horizontal direction, a conductive row gap is formed between the first roller body and the second roller body, and the conductive row gap is used for passing a conductive inner core of the conductive row.

[0011] By adopting the above technical solution, when the conductive inner core of the conductive row deviates on both sides along the width direction, the conductive inner core pushes the first roller body and the second roller body respectively, thereby causing the movable light-transmitting wheel to rotate, changing the light intensity in the receiving cavity, and thus detecting whether the conductive row has a deflection exceeding the design requirement through the light intensity sensor.

[0012] Optionally, the light shielding housing is equipped with a light source partition and a receiving partition, the light source partition divides the light source cavity into a first light-emitting chamber and a second light-emitting chamber, and the receiving partition divides the receiving cavity into a first receiving chamber and a second receiving chamber; The detection light sources are provided in plurality, and the plurality of detection light sources are respectively provided as a first light source and a second light source, and the first light source and the second light source are respectively located in a first light-emitting chamber and a second light-emitting chamber; The photometric sensors are provided in plurality, and the plurality of photometric sensors are respectively provided as a first sensor and a second sensor, and the first sensor and the second sensor are respectively located in a first receiving chamber and a second receiving chamber; There are a plurality of fixed light-transmitting holes, which are respectively configured as a first light-transmitting hole and a second light-transmitting hole. The first light-transmitting hole is connected to the first receiving chamber, and the second light-transmitting hole is connected to the second receiving chamber.

[0013] By adopting the above technical solution, when the first roller body is deflected under the action of the conductive inner core of the conductive row, the movable light-transmitting hole is driven to move toward the first light-transmitting hole, and then the movable light-transmitting hole is connected to the first light-transmitting hole, so that the first sensor receives the light from the first light source, thereby detecting the deflection of the conductive row in one direction.

[0014] When the second roller is deflected by the conductive inner core of the conductive row, the movable light-transmitting hole is driven to move toward the second light-transmitting hole, thereby connecting the movable light-transmitting hole to the second light-transmitting hole, so that the second sensor receives the light from the second light source, thereby detecting the deflection of the conductive row in another direction.

[0015] When detecting the deflection of the conductive strip in two directions, the light source partition and the receiving partition separate the light from the first light source and the second light source, so that the deflection detection in the two directions is not easily interfered with each other, which is conducive to improving the accuracy of the detection.

[0016] Optionally, the light-shielding housing is equipped with a driving bar slide rail, the driving bar slide rail is slidably matched with a light-transmitting wheel driving bar, and the light-transmitting wheel driving bar abuts against and matches the movable light-transmitting wheel; The light-transmitting wheel driving strip is installed on the vertical roller body through a hinged rod, and the two ends of the hinged rod are respectively rotatably matched with the vertical roller body and the light-transmitting wheel driving strip.

[0017] By adopting the above technical solution, when the first roller or the second roller rotates under the action of the deflection of the conductive inner core of the conductive row, the hinged rod is pulled or pushed, so that the hinged rod drives the transparent wheel drive bar to move, thereby pressing against and driving the movable transparent wheel to rotate.

[0018] Optionally, the vertical roller is rotatably matched with the detection frame through a roller sliding block, the roller sliding block slides in the horizontal direction to match the detection frame, and the vertical roller is rotatably matched with the roller sliding block, and the length of the hinged rod can be adjusted.

[0019] By adopting the above technical solution, it is convenient to adjust the position of the vertical roller according to the specifications of the conductive bar and the production line, thereby increasing the applicability of the detection module. For example, for a conductive bar with a larger width, the first roller and / or the second roller is slid, so as to detect the conveyance of conductive bars of different widths.

[0020] Optionally, the articulated rod includes a first screw, a second screw and a bidirectional screw tube, one end of the first screw is rotatably engaged with a vertical roller, the other end of the first screw is threadedly engaged with one end of the bidirectional screw tube, one end of the second screw is rotatably engaged with a light-transmitting wheel drive bar, the other end of the second screw is threadedly engaged with the other end of the bidirectional screw tube, and the threads at both ends of the bidirectional screw tube have opposite rotation directions.

[0021] By adopting the above technical solution, when the length of the hinged rod needs to be adjusted, the bidirectional screw tube is rotated, and the first screw rod and the second screw rod move closer to each other and then away from each other, thereby changing the length of the hinged rod.

[0022] When the position of the first roller or the second roller does not meet the specifications of the conductive bar and the production line, the first roller or the second roller is slid separately, and then the bidirectional screw is rotated to make the length of the hinge rod match the position of the first roller or the second roller, thereby reducing the occurrence of the first roller driving the second roller to deflect or the second roller driving the first roller to deflect, thereby ensuring the applicability and accuracy of the detection module.

[0023] Optionally, the light-transmitting wheel driving strip includes a driving strip slider and a driving strip flexible belt, the driving strip slider slides and fits in the driving strip slide rail, one side of the driving strip flexible belt is installed on the driving strip slider, and the other side of the driving strip flexible belt is tightly fitted in the movable light-transmitting wheel.

[0024] By adopting the above technical solution, the flexible belt of the driving strip drives the movable light-transmitting wheel through friction, thereby driving the movable light-transmitting wheel to rotate continuously, thereby reducing the occurrence of jamming of the movable light-transmitting wheel.

[0025] Optionally, the movable light-transmitting hole and the fixed light-transmitting hole both extend circumferentially around the axis of the movable light-transmitting wheel.

[0026] By adopting the above technical solution, the light intensity in the receiving cavity will be continuously changed according to the size of the area where the movable light-transmitting hole and the fixed light-transmitting hole overlap and connect, so that the specific degree of deflection of the conductive row can be obtained through the specific data of the light intensity, reducing the need for technicians to measure and adjust back and forth, and facilitating timely adjustments by technicians.

[0027] Optionally, the movable light-transmitting wheel is tightly matched with the fixed light-transmitting plate.

[0028] By adopting the above technical solution, it is helpful to reduce the light leakage between the movable light-transmitting hole and the fixed light-transmitting hole, so that the light intensity change in the receiving cavity does not obviously affect the detection accuracy.

[0029] Optionally, the detection frame is rotatably matched with a plurality of limit rollers, the plurality of limit rollers are distributed along the conveying direction of the conductive row, and the plurality of limit rollers are tightly matched with the vertical roller body from both sides.

[0030] By adopting the above technical solution, the two sides of the limiting roller are respectively tightly matched with the vertical roller body, so that the vertical roller body is not easily deflected along the conveying direction of the conductive row.

[0031] In summary, the present application includes at least one of the following beneficial technical effects: 1. The vertical roller is arranged close to the conductive inner core of the conductive row, so that the conductive inner core contacts the vertical roller when deflected and drives the vertical roller to rotate. When the vertical roller rotates, it drives the movable light-transmitting wheel to rotate, so that the movable light-transmitting hole is connected to the fixed light-transmitting hole, and then the light of the detection light source passes through the movable light-transmitting hole and the fixed light-transmitting hole to reach the receiving cavity. The photometric sensor detects the light intensity change in the cavity, thereby detecting whether the conductive row has a deflection that exceeds the design requirements; During the process of the photometric sensor detecting the light intensity in the receiving cavity, the light-shielding housing 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 ambient light, ensuring the detection accuracy of the photometric sensor, and reducing the adverse effects of lighting conditions on the detection of the deflection of the conductive bar.

[0040] The following is combined with Figure 1-7 This application is described in further detail.

[0041] The present application embodiment discloses a device for detecting the deflection of a conductive bar. Figure 1 The device for detecting the deflection of the conductive bar includes a detection frame 1, a vertical roller body 2 and a detection module.

[0042] Reference Figure 1 The top of the detection frame 1 is provided with two sliding key slots 101, which are distributed in the horizontal direction and extend in the horizontal direction. The detection frame 1 is slidably matched with two roller sliding blocks 11 in the horizontal direction through the two sliding key slots 101, and the two roller sliding blocks 11 are respectively locked in position by two bolts that penetrate through the sliding key slots 101 and threadedly matched with the roller sliding blocks 11.

[0043] Reference Figure 1 and Figure 2, there are two vertical roller bodies 2, which are respectively set 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 in the horizontal direction. The first roller body 201 and the second roller body 202 rotate by their own shafts, and the tops of the shafts of the first roller body 201 and the second roller body 202 rotate and match with two roller body sliding blocks 11, so that the first roller body 201 and the second roller body 202 revolve through the roller body sliding blocks 11, and the first roller body 201 and the second roller body 202 slide through the roller body sliding blocks 11 to adjust the distance between the first roller body 201 and the second roller body 202.

[0044] Reference Figure 1 A conductive row gap is formed between the first roller body 201 and the second roller body 202, and the conductive row gap is used to pass the conductive inner core of the conductive row. In the process of the conductive inner core passing through the conductive row gap, friction occurs between the conductive inner core and 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 on 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 in a vertical state under the action of gravity. When the conductive inner core deflects beyond the design range, the conductive inner core presses against and pushes the first roller body 201 or the second roller body 202 from the conductive row gap, 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 described in this 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 ambient light source.

[0045] Reference Figure 1 The detection frame 1 is rotatably matched with four limit rollers 12, which are divided into two groups. The two groups of limit rollers 12 are respectively located at the top and bottom of the vertical roller body 2. The two limit rollers 12 in the same group are distributed along the conveying direction of the conductive inner core, and the two limit rollers 12 are respectively tightly matched with the vertical roller body 2 from both sides, so that the vertical roller body 2 is not easy to deflect along the conveying direction of the conductive inner core, thereby improving the accuracy of the deflection signal of the vertical roller body 2.

[0046] Reference Figure 3 The detection module includes a light-shielding shell 3, a slide rail installation groove is opened on the top of the light-shielding shell 3, a driving bar slide rail 31 is installed inside the slide rail installation groove by bolts, and the driving bar slide rail 31 slides in the horizontal direction and cooperates with a light-transmitting wheel driving bar 32.

[0047] The light-transmitting wheel driving strip 32 includes a driving strip slider 321 and a driving strip flexible belt 322. The driving strip slider 321 slides and fits in the driving strip slide groove, and the driving strip flexible belt 322 is fixedly installed at the bottom of the driving strip slider 321. The driving strip flexible belt 322 is flexible, and in the embodiment of the present application, the driving strip flexible belt 322 is made of silicone so that the driving strip flexible belt 322 can fit closely to other components.

[0048] Reference Figure 1 and Figure 4 , the light-transmitting wheel driving bar 32 is respectively installed on each vertical roller body 2 through two hinged rods, and the hinged rods include a first screw rod 21, a second screw rod 22 and a bidirectional screw tube 23. The top end of the first screw rod 21 is rotationally matched with the vertical roller body 2, and the bottom end of the first screw rod 21 is threadedly matched with the top end of the bidirectional screw tube 23. The bottom end of the second screw rod 22 is rotationally matched with the light-transmitting wheel driving bar 32, and the top end of the second screw rod 22 is threadedly matched with the bottom end of the bidirectional screw tube 23. The threads of the top and bottom ends of the bidirectional screw tube 23 are in opposite directions, so that the length of the vertical roller body 2 can be changed by rotating the bidirectional screw tube 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 are stably in a vertical state under the action of gravity, reducing the shaking of the first roller body 201 or the second roller body 202.

[0049] Reference Figure 5 and Figure 6 A detection chamber is provided inside the light-shielding housing 3, and the detection chamber is closed so as to block ambient light from entering the detection chamber through the light-shielding housing 3, so that the interior of the detection chamber is not easily disturbed by ambient light; The detection module also includes a fixed light-transmitting plate 4, a movable light-transmitting wheel 5, a detection light source 6 and a photometric sensor 7. The movable light-transmitting wheel 5, the fixed light-transmitting plate 4, the detection light source 6 and the photometric sensor 7 are all located inside the detection chamber, so that the movable light-transmitting wheel 5, the fixed light-transmitting plate 4, the detection light source 6 and the photometric sensor 7 have relatively stable lighting conditions when working.

[0050] Reference Figure 5 and Figure 6, the fixed light-transmitting plate 4 divides the detection chamber into a light source chamber and a receiving chamber, thereby limiting the propagation of light between the light source chamber and the receiving chamber. The light-shielding housing 3 is fixedly installed with a light source partition 33, which is located in the light source chamber and is arranged in a "cross" shape. One side of the movable light-transmitting wheel 5 is rotatably matched with the light source partition 33, so that the movable light-transmitting wheel 5 rotates relative to the light-shielding housing 3 through the light source partition 33. The other side of the movable light-transmitting wheel 5 is tightly matched with one side of the fixed light-transmitting plate 4, so that light is not easy to leak from 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 abuts against the bottom of the driving strip flexible belt 322, so that the driving strip flexible belt 322 drives the movable light-transmitting wheel 5 to rotate through the friction between the driving strip flexible belt 322 and the movable light-transmitting wheel 5. The light-shielding housing 3 is also fixedly installed with a receiving partition 34, which is located in the receiving chamber and is arranged in a "T" shape. The receiving partition plate 34 is tightly fitted to the other side of the fixed light-transmitting plate 4 , so that light is not easily leaked from the gap between the receiving partition plate 34 and the fixed light-transmitting plate 4 .

[0051] The light source partition 33 divides 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 33, and the light propagation between the first light-emitting chamber 301 and the second light-emitting chamber 302 is blocked by the light source partition 33. The receiving partition 34 divides 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 34, and the light propagation between the first receiving chamber 303 and the second receiving chamber 304 is blocked by the receiving partition 34. In addition, in the embodiment of the present application, the first receiving chamber 303 is arranged corresponding to the first light-emitting chamber 301, and the second receiving chamber 304 is arranged corresponding to the second light-emitting chamber 302.

[0052] There are two detection light sources 6, which are respectively set as the first light source and the second light source. The first light source and the second light source are both fixedly mounted on the light-shielding housing 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 photometric sensor 7 is used to detect the light intensity in the receiving cavity, and the photometric sensor 7 is connected to an external detection system (not shown in the figure), and the detection system is used to output the deflection mapped by the photometric sensor 7. There are two photometric sensors 7, which are respectively set as the first sensor and the second sensor, and the first sensor and the second sensor are both fixedly mounted on the light-shielding housing 3, and the first sensor and the second sensor are respectively located in the first receiving chamber 303 and the second receiving chamber 304.

[0053] The fixed light-transmitting plate 4 is provided with two fixed light-transmitting holes, which are respectively set as a first light-transmitting hole 401 and a second light-transmitting hole 402. The first light-transmitting hole 401 and the second light-transmitting hole 402 are both located at the top of the fixed light-transmitting plate 4, and the first light-transmitting hole 401 and the second light-transmitting hole 402 are respectively connected to the first receiving chamber 303 and the second receiving chamber 304, and the first light-transmitting hole 401 and the second light-transmitting hole 402 both extend circumferentially around the axis of the movable light-transmitting wheel 5. The movable light-transmitting wheel 5 is provided with two movable light-transmitting holes 501, which both extend circumferentially around the axis of the movable light-transmitting wheel 5. The two movable light-transmitting holes 501 are respectively arranged corresponding to the first light-transmitting hole 401 and the second light-transmitting hole 402, and the two movable light-transmitting holes 501 are connected or disconnected with the first light-transmitting hole 401 or the second light-transmitting hole 402 through the rotation of the movable light-transmitting wheel 5, and then the light intensity in the first receiving chamber 303 or the second receiving chamber 304 is continuously changed by the connection and disconnection of the movable light-transmitting holes 501 and the first light-transmitting hole 401 or the second light-transmitting hole 402, so that the first sensor or the second sensor outputs the corresponding light intensity value.

[0054] The implementation principle of a device for detecting the deflection of a conductive row in an embodiment of the present application is as follows: when the conductive inner core has an excessively large deflection, the conductive inner core will fit tightly against one of the vertical rollers 2, thereby pushing the vertical roller 2 that was originally in a vertical state to swing.

[0055] Combination Figure 7 When the vertical roller 2 swings, the light-transmitting wheel driving bar 32 is driven to move horizontally along the Arrow-X direction through the hinged rod, and then the movable light-transmitting wheel 5 is driven to rotate along the Arrow-Y direction through the friction force, so that part or the whole of one of the movable light-transmitting holes 501 overlaps and communicates with the fixed light-transmitting hole, thereby changing 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 the magnitude of the deflection of one side of the conductive inner core is determined according to the light intensity detected by the first detector and the second detector.

[0056] In the process of the first sensor and the second sensor detecting the light intensity in the receiving cavity, the light shielding housing 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 photometric sensor 7, and thus reducing the adverse effect of the lighting conditions on the detection of the deflection of the conductive strip. The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
