DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1 to 4 As shown, the present invention provides a cable straightening and cutting device, comprising a cable reel supporting mechanism, a cable straightening mechanism, a cable measuring and cutting mechanism, and a cable collecting mechanism, which are sequentially arranged along the cable transport direction;

[0031] The cable drum support mechanism is used to support the cable drum;

[0032] The cable straightening mechanism is used to straighten the unfolded cables and guide the transportation of the cables;

[0033] The cable measuring and shearing mechanism is used to measure the diameter of the straightened cable and to shear the cable after the diameter is measured;

[0034] The cable collection mechanism is used to classify and collect the cut cables.

[0035] As a technical solution that can be added to the present invention, a sensor is provided between the cable drum supporting mechanism and the cable straightening mechanism, and the sensor is used to sense whether the cables on the cable drum have been fully laid out. When it is detected that the laying out has been completed, a buzzer alarm is issued to remind the workers to replace the new cable drum.

[0036] A sensor is a detection device and is the primary link in achieving automatic detection and automatic control. The characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systematization, and networking. Usually, they are divided into ten categories according to their basic sensing functions: thermal sensors, photosensitive elements, gas sensors, force sensors, magnetic sensors, humidity sensors, sound sensors, radiation sensors, color sensors, and taste sensors. They are widely used in various automotive, industrial, consumer and other fields. Sensors can sense the information being measured and can transform the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control.

[0037] The functions of sensors are often compared to the five major human sensory organs: light sensors - vision, sound sensors - hearing, gas sensors - smell, chemical sensors - taste, pressure sensors, temperature sensors, fluid sensors - touch, classification of sensitive components: physical type, based on physical effects such as force, heat, light, electricity, magnetism and sound. Chemical type, based on the principle of chemical reaction. Biological type, based on molecular recognition functions such as enzymes, antibodies, and hormones.

[0038] The sensor of the present invention can be selected as a visual sensor, which refers to a sensor with the ability to capture thousands of pixels of light from a whole image. The clarity and fineness of the image are usually measured by resolution, expressed in the number of pixels. The visual sensor has thousands of pixels that capture light from a whole image. The clarity and fineness of the image are usually measured by resolution, expressed in the number of pixels. After capturing the image, the visual sensor compares it with the reference image stored in the memory to make an analysis. For example, if the visual sensor is set to identify a machine part with eight bolts correctly inserted, the sensor knows that it should reject a part with only seven bolts or a part with misaligned bolts. In addition, no matter where the machine part is located in the field of view, no matter whether the part is rotated within 360 degrees, the visual sensor can make a judgment. Application field: The low cost and ease of use of visual sensors have attracted machine designers and process engineers to integrate them into various applications that once relied on manual, multiple photoelectric sensors, or no inspection at all. Industrial applications of visual sensors include inspection, metrology, measurement, orientation, defect detection and sorting. Here are just a few examples: In an automotive assembly plant, checking that the glue bead applied by the robot to the door frame is continuous and of the correct width; in a bottling plant, verifying that the bottle cap is properly sealed, the fill level is correct, and that no foreign matter has fallen into the bottle before capping; in a packaging line, ensuring that the correct package label is affixed in the correct position; in a pharmaceutical packaging line, checking whether there are damaged or missing tablets in the blister pack of aspirin tablets; in a metal stamping company, inspecting stamped parts at a speed of more than 150 tablets per minute, more than 13 times faster than manual inspection.

[0039] You can also choose a laser sensor, which is a sensor that uses laser technology for measurement. It consists of a laser, a laser detector and a measuring circuit. The laser sensor is a new type of measuring instrument. Its advantages are that it can achieve non-contact long-distance measurement, fast speed, high accuracy, large range, and strong resistance to light and electrical interference. When the laser sensor is working, the laser emitting diode first emits a laser pulse at the target. After being reflected by the target, the laser scatters in all directions. Part of the scattered light returns to the sensor receiver and is received by the optical system and imaged onto the avalanche photodiode. The avalanche photodiode is an optical sensor with an internal amplification function, so it can detect extremely weak light signals and convert them into corresponding electrical signals. Non-contact long-distance measurement can be achieved by using the high directivity, high monochromaticity and high brightness of the laser. Laser sensors are commonly used to measure physical quantities such as length (ZLS-Px), distance (LDM4x), vibration (ZLDS10X), speed (LDM30x), and orientation. They can also be used for flaw detection and monitoring of atmospheric pollutants. Usually, according to their basic sensing functions, they can be divided into ten categories: thermal sensors, photosensitive elements, gas sensors, force sensors, magnetic sensors, humidity sensors, sound sensors, radiation sensitive elements, color sensitive elements and taste sensitive elements (some people have divided sensitive elements into 46 categories).

[0040] The sensor can also select a cable core break detection device to realize wire and cable core break detection or wire break detection.

[0041] The detection device includes: a shell, which is a square box-shaped structure as a whole, and is hollow inside for arranging various circuit components. The upper surface of the shell is provided with a display screen for displaying the detection results, and is also provided with input components such as knobs and buttons for inputting control instructions to the detection device. Two relatively parallel flat plates are connected and arranged on one side of the shell, namely an upper plate and a lower plate, and a cable channel for the cable to pass through is formed between the upper plate and the lower plate. When the cable is detected, it is inserted into the cable channel from the side.

[0042] The probe is arranged on the shell, specifically, the probe is arranged on the upper plate, and is detachably connected to the upper plate by bolts. The probe is an inductive sensor commonly used in the detection process, and is used to sense the inductance strength of the energized cable. The probe is vertically downward, and is used to be close to the cable during the detection process.

[0043] The detection circuit is electrically connected to the probe and is used to receive the sensing signal from the probe and process the sensing signal.

[0044] The response module is electrically connected to the detection circuit and is used to respond according to the sensing signal. The response is mainly based on the change in inductance strength represented by the sensing signal. For example, when the inductance decreases significantly, a response is sent out to determine the position of the broken core.

[0045] The clamping rolling module is arranged in the cable channel. The clamping rolling module comprises an upper roller and a lower roller arranged opposite to each other. The lower roller is arranged on the lower plate and connected to the bottom wall of the cable channel. The upper roller is elastically connected to the top wall of the cable channel so that the upper roller can slide up and down relative to the lower roller, thereby making the relative distance between the upper roller and the lower roller adjustable. When the detection device is detecting, the upper roller is pulled up to increase the distance between the upper roller and the lower roller, and the cable is placed between the upper roller and the lower roller. The upper roller is loosened so that the upper roller moves downward under the action of elastic force. The upper roller cooperates with the lower roller to clamp the cable from both sides. When the detection device moves along the cable, the upper roller and the lower roller roll to make the detection device move smoothly.

[0046] The clamping rolling module includes an upper roller and a lower roller. The upper roller is elastically connected to the top wall of the cable channel. During detection, the upper roller and the lower roller clamp the two sides of the cable. When the detection device moves along the cable, the upper roller and the lower roller roll to make the detection device move smoothly. Through the clamping rolling module, the relative distance between the probe and the cable is stable during the movement of the detection device along the cable, and the probe can maintain a position corresponding to the cable, which can effectively avoid false alarms caused by the probe deviating from the cable or the distance from the cable being too large, and can significantly improve the accuracy of the detection of the broken core position of the detection device, improve the maintenance efficiency, and reduce the maintenance cost.

[0047] The present invention clamps the relative position between the rolling module limit detection device and the cable to keep the relative position between the probe and the cable stable. Maintenance personnel do not need to deliberately control the probe position, which can effectively reduce the operating difficulty of the detection process and the labor intensity of maintenance personnel and improve maintenance efficiency.

[0048] Furthermore, the clamping and rolling module further comprises:

[0049] The connecting rod and the upper roller are rotatably arranged in a roller seat, the lower end of the connecting rod is connected to the upper surface of the roller seat, a connecting hole adapted to the connecting rod is formed on the top wall of the cable channel, and the connecting rod is movably inserted into the connecting hole so that the connecting rod can slide up and down in the connecting hole.

[0050] The elastic member is specifically a spring, which is sleeved outside the connecting rod. One end of the elastic member is connected to the upper roller, and the other end is connected to the top wall of the cable channel. The elastic member is used to provide elastic force to push the upper roller downward so that the upper roller and the lower roller fit together. The elastic member can make the upper roller have a downward movement tendency to push, so that the upper roller and the lower roller are naturally clamped, so that the position of the probe and the cable remains stable during the detection process, so that the accuracy of the detection result is high.

[0051] Furthermore, the clamping and rolling module further comprises:

[0052] The handle is arranged on the top surface of the shell, located on one side of the connecting rod. The end of the handle is hinged to the upper end of the connecting rod, and the middle part is hinged to the top surface of the shell. By shaking the other end of the handle, the upper end of the connecting rod can be pulled up, thereby driving the upper roller to move upward, so that the cable can be placed between the upper roller and the lower roller. The handle can facilitate operation by maintenance personnel.

[0053] Furthermore, the clamping and rolling module further comprises:

[0054] The motor is arranged inside the shell and is located beside the lower roller. The motor is linked with the lower roller to drive the lower roller to rotate. The motor is electrically connected to the detection circuit. The motor can drive the lower roller to rotate, so that the detection device has a tendency to move along the cable, which can make the movement of the detection device smoother during the detection process, further improve the detection efficiency and reduce the labor intensity of maintenance personnel.

[0055] Furthermore, the cable core breakage detection device further comprises:

[0056] The clamping assembly is an electric clamp. The clamping assembly includes two relatively movable clamping arms, which are respectively arranged on both sides of the cable travel path. The clamping assembly is electrically connected to the detection circuit. When the detection circuit senses the broken core position, it outputs a signal to the response module to make the response module respond. At the same time, the two clamping arms of the clamping assembly are controlled to move toward each other, so that the clamping assembly clamps the cable, thereby fixing the relative position of the detection device and the cable, which is conducive to the detection personnel to quickly find the broken core position, avoid missed detection, and further improve the detection efficiency.

[0057] More specifically, the clamping assembly is arranged at the rear end of the probe and close to the probe. During the detection process, the detection device moves continuously along the cable. When the probe senses the broken core position, the detection circuit receives the sensing signal to control the clamping assembly to clamp. Due to the relative position of the clamping assembly and the probe, the clamping position of the clamping assembly is close to the broken core position of the cable, which is beneficial for maintenance personnel to quickly determine the broken core position.

[0058] The inner side surface of the clamp arm is formed with a plurality of clamp teeth, which are used to increase the relative friction between the clamp arm and the cable, so that the clamp assembly is not easily displaced after clamping the cable, thereby making the detection of the broken core position accurate.

[0059] Furthermore, in this embodiment, the detection circuit includes a receiving unit, a filtering unit, a rectifying unit and an amplifying unit which are cascaded in sequence, and the receiving unit is connected to the probe signal to receive the sensing signal of the probe. The filtering unit uses the LM3580D chip for filtering. The rectifying unit uses the DB2W31900L chip for rectification. The amplifying unit uses a three-stage amplification structure in which three transistors are connected in series. The detection circuit filters, rectifies and amplifies the sensing signal of the probe and converts it into an electrical signal that can be recognized by the processing unit. The processing unit uses an MCU (Microcontroller Unit). The processing unit determines the inductance strength of the detection position according to the input electrical signal. When the inductance strength is significantly weakened compared to the previous moment or is lower than a preset threshold, the processing unit determines that the cable at that location has a core break phenomenon, and controls the response module to send a response to prompt the maintenance personnel. The above-mentioned detection circuit structure can accurately detect the position of the cable core break, and has the advantages of sensitive response and accurate detection.

[0060] Furthermore, the response module includes a buzzer and an indicator light, and both the buzzer and the indicator light are electrically connected to the output end of the detection circuit so as to simultaneously emit sound and light prompts when the detection circuit detects the broken core position, thereby significantly prompting maintenance personnel. At the same time, it can also avoid missed detection when the buzzer or the indicator light is damaged alone, thereby improving the reliability of the detection device.

[0061] Furthermore, the detection device also includes a power module, which is a rechargeable power supply and is electrically connected to the probe, the detection circuit, the response module and other components respectively, for supplying power to each component.

[0062] Furthermore, the cable straightening mechanism includes a support platform 9, and two support seats 12 are fixedly connected to the top of the support platform 9. The two support seats 12 are vertically spaced apart, and a straightening part is rotatably arranged between the tops of the two support seats 12. A driving part is also arranged on the top of the support platform 9, and the driving part is transmission-connected to the straightening part.

[0063] Furthermore, the straightening portion includes a rotating drum 13, both ends of which are rotatably connected to the two support seats 12 respectively, the driving portion is transmission-connected to the rotating drum 13, a plurality of fixed shafts 23 are arranged inside the rotating drum 13, and the plurality of fixed shafts 23 are arranged at equal intervals along the circumferential direction of the inner wall of the rotating drum 13, both ends of the fixed shafts 23 are fixedly connected to sleeves 25 respectively, one end of the sleeve 25 away from the fixed shaft 23 is slidably connected to one end of the central shaft 26, the other end of the central shaft 26 is fixedly connected to the inner wall of the rotating drum 13, a spring 27 is sleeved on the outer side of the central shaft 26, both ends of the spring 27 are fixedly connected to the end of the sleeve 25 and the inner wall of the rotating drum 13 respectively, and a rotating roller 24 is rotatably sleeved on the middle of the outer wall of the fixed shaft 23.

[0064] Furthermore, the driving part includes a motor 14, which is fixedly connected to the top of the support platform 9, and the motor 14 is located between the two support seats 12. The output shaft of the motor 14 is fixedly connected to a driving roller 15, and the outer wall of the rotating drum 13 is fixedly sleeved with a driven roller 16, which is connected to the driving roller 15 in a transmission manner.

[0065] Furthermore, a guide driver 17 and a guide driver 2 18 are fixedly connected to the top of the support platform 9. The guide driver 17 and the guide driver 2 18 are coaxially arranged with the straightening part. The guide driver 17 is arranged between the straightening part and the cable drum supporting mechanism, and the guide driver 2 18 is arranged between the straightening part and the cable measuring and shearing mechanism.

[0066] As an additional implementation scheme of the present invention, both ends of the fixed shaft 23 and the rotating roller 24 are configured in a smooth transition form to ensure that the cable can smoothly enter between the fixed shafts 23 without getting stuck.

[0067] The form of smooth transition belongs to the guiding feature. Design guiding features help improve the usability and user experience of the product. In product design, guiding features can help users understand and use the product more quickly, reduce learning costs, and improve operational efficiency. Design guiding features can enhance the reliability and safety of the product. Design guiding features also help improve the production efficiency and quality of the product.

[0068] Guidance features include the following:

[0069] Guide post and guide groove: Guide posts are usually designed in the shape of long strips or cylinders for insertion into guide grooves. Guide grooves are grooves that match the guide posts and can accommodate the guide posts and guide their movement. This design allows parts to be quickly aligned during assembly and reduces assembly errors.

[0070] Dowel pins and locating holes: Dowel pins are fixed or removable cylindrical parts that are inserted into locating holes. Locating holes are round holes that match the dowel pins and are used to receive the dowel pins. This design method can accurately fix the position of parts and ensure assembly accuracy.

[0071] Bevel and mortise and tenon structure: Bevel design is often used for the contact surface of parts and components, and the guiding effect is achieved through the angle and length of the bevel. The mortise and tenon structure uses the protruding tenon and the sunken mortise to cooperate to achieve the positioning and guidance of parts and components.

[0072] Boss and groove: Boss is the protruding part on the part, usually used to support or position other parts. Groove is the concave part that matches the boss, used to accommodate the boss and guide it to be assembled correctly.

[0073] Bevel is a common guide feature that can guide and position components when they are in contact. Bevel design can reduce friction during assembly, making it easier for components to get into the correct position. Bevel can also tolerate dimensional errors of components to a certain extent, thus increasing the tolerance of assembly.

[0074] Rounded corners are also a common guide feature. They are mainly used to eliminate sharp corners between parts and avoid scratches or collisions during assembly. The rounded corner design can make the contact between parts smoother and improve the smoothness of assembly.

[0075] Guide posts and guide slots are more precise guide features. Guide posts are usually designed to be cylindrical or conical and can be inserted into corresponding guide slots to play a role in positioning and fixing.

[0076] The design points of the guide feature include the following:

[0077] The guide feature should be designed to ensure that it contacts the reference part first during assembly; this ensures that the guide function is effective and avoids assembly problems caused by misalignment or misalignment between parts.

[0078] The size of the guide feature is also a key factor in the design. Generally speaking, the larger the guide feature, the more tolerant it is to the dimensional errors of the parts, thus allowing for greater misalignment during the assembly process. This helps reduce the need for repeated adjustments and careful alignment during the assembly process, and improves assembly efficiency;

[0079] The specific forms of guide features are also varied. Common guide features include bevels, rounded corners, guide posts and guide grooves. The design of these features needs to take into account the specific usage scenarios and assembly requirements of the product to ensure that they can effectively guide the correct assembly of parts;

[0080] Error-proofing design is also an important aspect of guide feature design. For example, by designing a unique correct assembly position or obvious error-proofing markings, it is possible to prevent the mis-assembly or wrong assembly of parts and improve the accuracy and reliability of assembly.

[0081] After the cable drum is unwound, the free end of the cable first passes through the guide driver 17, and after being guided and driven by the guide driver 17, enters between several fixed shafts 23 inside the drum 13, and then passes through the guide driver 2 18. The guide driver 17 and the guide driver 2 18 jointly provide the power for the cable to move forward. The gap between several rotating rollers 24 is smaller than the diameter of the cable, so that when the cable passes through the rotating rollers 24, all the rotating rollers 24 can be pressed against the outer surface of the cable by the elastic force of the central shaft 26. As the cable continues to move forward in the drum 13, the motor 14 drives the driving roller 15 to rotate, and then drives the drum 13 to rotate through the transmission cooperation with the driven roller 16. The drum 13 simultaneously drives all the fixed shafts 23 to rotate around the outer wall of the cable.
