Description

TECHNICAL FIELD

[0001] The application relates to the technical field of wire and cable detection, in particular to a detection robot for wire and cable production. BACKGROUND

[0002] A wire and cable is usually composed of a cable core for transmitting power or electrical signals and a sheath for protection and insulation. After production, the wire and cable needs to be subjected to a series of strict detection to ensure that its quality meets the relevant standards and requirements. The abrasion resistance detection of the wire and cable is an important link for evaluating the abrasion resistance of the insulation or sheath material. The wire and cable used in environments that are frequently moved or have friction, such as industrial equipment and wire and cable inside vehicles, has a poor sheath that is prone to breakage, resulting in short circuit or electric leakage, which poses a safety hazard. Therefore, the abrasion resistance of the cable directly affects the service life and safety of the product.

[0004] In the above technical solution, the outer sheath material of the wire and cable is prone to brittle fracture during friction with the grinding wheel, forming fine debris. The debris is prone to softening at high temperature during friction, and the softened debris fills the gap of the grinding wheel to form a "debris layer", which reduces the surface roughness of the grinding wheel, causes the friction coefficient to decrease, and slows down the wear rate, resulting in detection data that does not meet the standard. SUMMARY

[0005] The purpose of the present application is to provide a detection robot for wire and cable production, which reduces the possibility of debris adhering to the grinding wheel during abrasion resistance detection of the cable.

[0006] The detection robot for wire and cable production provided by the present application adopts the following technical solution A detection robot for wire and cable production, comprising a workbench, wherein the workbench is provided with: a clamping assembly, the clamping assembly comprising two clamping parts slidingly arranged on the workbench, and a cable being clamped between the two clamping parts; a grinding wheel, the grinding wheel being horizontally rotatably arranged on the workbench, and the outer peripheral wall of the grinding wheel being in close abutment with the cable for polishing the cable; The annular air flow cover is coaxial with the grinding wheel and covers the grinding wheel, a plurality of multi-angle nozzles are distributed on the inner circumferential wall of the annular air flow cover in the circumferential direction, the nozzles spray air flow at an angle with the tangential direction of the grinding wheel, and the spraying direction is the same as the rotating direction of the grinding wheel. The guide groove is arranged on the workbench, the discharge port of the guide groove is connected with the inlet of the scrap collecting groove, and the scrap is conveyed into the scrap collecting groove.

[0007] Optionally, the guide groove is arranged on both sides of the cable, and a strip-shaped nozzle is arranged in the guide groove, the strip-shaped nozzle sprays air flow towards the cable axis, forms an orthogonal air flow field with the spiral air curtain, and the air flow sprayed by the strip-shaped nozzle can guide the scrap into the guide groove.

[0008] Optionally, the air flow sprayed by the strip-shaped nozzle forms a pressure difference above the guide groove, and pushes the scrap to move in the guide groove.

[0009] Optionally, the guide groove is arranged on the workbench in an inclined manner, and one end of the guide groove at a lower elevation is connected with the scrap collecting groove.

[0010] Optionally, the angle of the nozzle towards the tangential direction of the grinding wheel is 45°, and the air injection pressure is 0.5-1.5 MPa.

[0011] Optionally, the strip-shaped nozzle is arranged along the length direction of the guide groove, the air injection pressure of the strip-shaped nozzle is 0.2-0.5 MPa, and the included angle between the strip-shaped nozzle and the workbench is 30°-60°.

[0012] Optionally, the air flow control system further comprises a vortex air compressor and an air flow adjusting valve, the vortex air compressor is used for providing air flow for the annular air flow cover and the strip-shaped nozzle, and the air flow adjusting valve is arranged on the air inlet pipeline of the annular air flow cover and the strip-shaped nozzle, so as to control the air flow flow rate and pressure entering the annular air flow cover and the strip-shaped nozzle.

[0013] Optionally, the air flow control system further comprises a PLC controller, the PLC controller is used for controlling the start-stop and motion state switching of the vortex air compressor, the air flow adjusting valve and the driving source.

[0014] Optionally, a wind speed sensor is arranged at the annular air flow cover and the strip-shaped nozzle, and the wind speed sensor is used for monitoring the speed of the air flow in real time, so as to feed back to the PLC controller to issue corresponding instructions.

[0015] In summary, the present application has at least one of the following beneficial technical effects: 1. When the nozzle sprays air flow on the grinding wheel, in the first aspect, the air flow can cool the outer circumferential wall of the grinding wheel, reduce the temperature of the outer circumferential wall of the grinding wheel, and reduce the possibility of melting and adhering of the scrap on the outer circumferential wall of the grinding wheel.

[0016] In a second aspect, during normal wear and tear of the grinding wheel, the abrasive particles on the surface of the grinding wheel gradually fall off or wear out, forming a uniform wear pattern. However, the adhesion of debris on the grinding wheel changes the roughness and hardness distribution of the grinding wheel surface. The adhered debris can fill the gaps on the surface of the grinding wheel, making the surface of the grinding wheel relatively smooth, reducing the effective contact area between the abrasive particles and the surface of the cable, and thus reducing the grinding ability of the grinding wheel on the cable. This may result in the detected cable wear resistance data being higher than the actual situation, and the cable wear resistance cannot be truly reflected. The multi-angle nozzles in the annular air flow cover spray air flow to the grinding wheel at a specific angle, and the spray angle is consistent with the rotation direction of the grinding wheel, forming a spiral air flow. The spiral air flow has a tangential component along the grinding wheel, which can generate a thrust in the same direction as the rotation of the grinding wheel. The debris is pushed away from the contact area between the grinding wheel and the wire and cable under the action of the force, avoiding the accumulation of debris in the polishing area and affecting the polishing effect and the surface quality of the cable. In a third aspect, the shape of the spiral air flow is similar to a rotating cone, which has a certain convergence effect. It can concentrate the debris ground from the grinding wheel inside the air curtain, so that the debris does not randomly fly around, but moves in a relatively concentrated manner away from the cable under the constraint of the spiral air curtain, facilitating the subsequent collection and processing of the debris.

[0017] In a fourth aspect, there is a certain pressure difference inside the spiral air flow. The air flow near the surface of the grinding wheel has a high speed and a low pressure, while the outer air flow has a relatively high pressure. This pressure difference will generate an upward buoyancy on the debris, making the debris in a suspended state to a certain extent, reducing the contact and friction between the debris and the surface of the cable, and reducing the possibility of secondary scratches or contamination of the cable surface by the debris.

[0018] 2. The strip-shaped nozzle sprays air flow towards the cable, forming an air flow field around the cable that is directed towards the guide groove. On the one hand, it can prevent the debris from scattering in the direction away from the sides of the cable; on the other hand, when the debris blown by the nozzle at the grinding wheel moves near the cable, the air flow generated by the strip-shaped nozzle can further guide the debris into the guide groove.

[0019] 3. The air flow sprayed by the strip-shaped nozzle will form a pressure difference above the guide groove, pushing the debris to move in the guide groove. At the same time, the remaining energy of the air flow sprayed by the nozzle in the air flow cover can continue to push the debris forward in the guide groove during the process of guiding the debris into the guide groove, thereby transporting the debris into the debris collection groove.

DETAILED DESCRIPTION

[0022] The following will be described in detail with reference to the accompanying drawings Figure 1 - the accompanying drawings Figure 4 , the present application will be further described in detail.

[0023] Reference Figure 1 and Figure 2 , the present application provides a detection robot for wire and cable production, referring to Figure 1 , including workbench 1 and air flow control system 8, the workbench 1 is provided with clamping assembly 2 for fixing both ends of the cable 9, the clamping assembly 2 includes clamping part slidingly arranged at both ends of the workbench 1. The workbench 1 is fixedly connected with linear guide rail 21 at both ends, the clamping part includes sliding seat 22 slidingly arranged on the linear guide rail 21, the sliding seat 22 is fixedly connected with clamp 23, and the cable 9 is fixed in the two clamps 23. The clamp 23 can clamp cables 9 of different sizes, which enhances the adaptability of the clamping assembly 2, and the clamp 23 is arranged on the sliding seat 22, so that the cable 9 can reciprocate along the length direction of the linear guide rail 21, which improves the contact area of the cable 9 and the grinding wheel 3, and further can test the cable 9 at multiple points, and improves the accuracy of the wear resistance detection of the cable 9.

[0024] Reference Figure 2 and Figure 3 , the workbench 1 is provided with a grinding wheel 3 rotatingly arranged thereon, the grinding wheel 3 is horizontally placed on the workbench 1, and the workbench 1 away from the grinding wheel 3 is provided with a driving source 31 for driving the grinding wheel 3 to rotate, the driving end of the driving source 31 is fixedly connected with the axis of the grinding wheel 3 through the workbench 1, and the outer peripheral wall of the grinding wheel 3 abuts against the cable 9.

[0025] The cable 9 is passed through the clamp 23, and the cable 9 is locked by the clamp 23, the two sliding seats 22 are synchronously reciprocated on the corresponding linear guide rails 21, and the driving source 31 can drive the grinding wheel 3 to rotate, the contact surface between the grinding wheel 3 and the cable 9 is subjected to one-way friction due to the rotation of the grinding wheel 3, and the dynamic wear resistance experiment of the cable 9 is carried out, and the clamping part drives the cable 9 to move at low speed on the workbench 1. Reciprocating movement can simulate the continuous sliding friction of the cable 9.

[0026] With reference to Figure 3 And Figure 4 , the workbench 1 is provided with an annular air flow cover 4, the annular air flow cover 4 covers the grinding wheel 3, and the annular air flow cover 4 is coaxial with the grinding wheel 3, and the annular air flow cover 4 is provided with a gap hole 41 for the cable 9 to pass through. The bottom of the annular air flow cover 4 is fixedly connected with a plurality of support rods 42, the plurality of support rods 42 are arranged in a ring shape, and the end portions of the support rods 42 are fixedly connected with buckles 43. The workbench 1 is provided with a groove 11 for inserting the support rods 42, and the bottom of the groove 11 is provided with a clamping groove 12 for clamping the buckle 43. The clamping groove 12 and the groove 11 form an L-shaped groove body, and the support rod 42 is a thermoplastic elastomer.

[0027] The support rod 42 is pushed towards the center of the annular air flow cover 4, so that the support rod 42 can be inserted into the groove 11. When the buckle 43 enters the clamping groove 12, the support rod 42 is elastically deformed in the groove 11, and the buckle 43 is pushed to abut against the inner wall of the clamping groove 12. At this time, the buckle 43 is located in the clamping groove 12, and the top of the buckle 43 abuts against the top wall of the clamping groove 12, thereby fixing the annular air flow cover 4. The buckle 43 and the clamping groove 12 cooperate to facilitate the disassembly and assembly of the annular air flow cover 4, thereby facilitating the replacement of the severely worn grinding wheel 3.

[0028] With reference to Figure 4 The inner circumferential wall of the annular air flow cover 4 is distributed with a plurality of multi-angle nozzles 5 in the circumferential direction, the opening direction of the nozzle 5 is at an angle of 45° with the tangential direction of the grinding wheel 3, the jet pressure of the nozzle 5 is between 0.5-1.5MPa, and the jet direction of the nozzle 5 is the same as the rotation direction of the grinding wheel 3.

[0029] During the friction between the grinding wheel 3 and the cable 9 during the rotation of the grinding wheel 3, the temperature of the surface of the grinding wheel 3 will rise, and the waste debris falling off the cable 9 during the friction will be hot and will adhere to the surface of the grinding wheel 3. The adhered waste debris may fill the gaps on the surface of the grinding wheel 3, making the surface of the grinding wheel 3 relatively smooth, reducing the effective contact area between the abrasive particles and the surface of the cable, and thus reducing the grinding ability of the grinding wheel 3 on the cable. This may cause the detected cable wear resistance data to be higher than the actual situation, and cannot truly reflect the wear resistance of the cable. The jet flow of the nozzle 5 can reduce the temperature of the surface of the grinding wheel 3 and reduce the possibility of waste debris melting and adhering to the outer circumferential wall of the grinding wheel 3.

[0030] Reference Figure 4 The nozzles 5 on the inner wall of the annular airflow hood 4 are evenly distributed along the circumferential direction, and the spray direction is tangential to the outer wall of the grinding wheel 3 and in the same direction of rotation as the grinding wheel 3. When the airflow is ejected from these nozzles 5, a spiral airflow is formed around the grinding wheel 3. The spiral airflow has a velocity component along the tangent direction of the grinding wheel 3, which can generate a thrust in the same direction as the rotation of the grinding wheel 3. Under the action of this force, waste chips move along the direction of the spiral air curtain, thereby being pushed away from the contact area between the grinding wheel 3 and the cable 9, preventing waste chips from accumulating in the grinding area and affecting the grinding effect and cable surface quality.

[0031] The spiral airflow, shaped like a rotating cone, has a certain convergence effect. It can concentrate the waste chips from the grinding wheel 3 within the air curtain, preventing them from scattering around. Instead, they are confined by the spiral air curtain and move in a relatively concentrated direction away from the cable 9, facilitating their subsequent collection and disposal.

[0032] At the same time, a certain pressure difference exists within the spiral airflow: the airflow near the grinding wheel 3 has a high velocity and low pressure, while the airflow outside has a relatively high pressure. This pressure difference creates an upward buoyancy force on the waste chips, keeping them suspended to a certain extent, reducing contact and friction between the waste chips and the cable surface, and reducing the possibility of waste chips causing secondary scratches or contamination on the cable surface.

[0033] The 45° angle between the opening direction of the nozzle 5 and the tangent direction of the grinding wheel 3 is a relatively balanced angle. It can provide sufficient blowing force to clear debris without excessively interfering with the rotation of the grinding wheel 3 and the operation of the cable 9 due to the airflow angle being too perpendicular or parallel to the tangent of the grinding wheel 3. If the angle is too perpendicular, it may produce greater resistance to the grinding wheel 3, affecting its rotational stability. It may also produce a large impact force on the cable 9, causing the cable 9 to shift its position or damage its surface. If the angle is too parallel, it may not be able to effectively penetrate the contact area between the grinding wheel 3 and the cable 9 to clear debris. Therefore, the 45° angle can effectively ensure the normal operation of the grinding wheel 3 and the cable 9 while clearing debris.

[0034] The annular airflow cover 4 is made of high-temperature resistant PC material. The annular airflow cover 4 can withstand the heat generated by the high-speed friction of the grinding wheel 3, preventing the annular airflow cover 4 from being deformed under high temperature conditions, thereby extending the service life of the annular airflow cover 4.

[0035] Reference Figure 2The workbench 1 is provided with a flow guide groove 6, which is arranged on both sides of the cable 9, and a strip-shaped nozzle 61 is arranged in the flow guide groove 6. The strip-shaped nozzle 61 is arranged along the length direction of the cable 9, and sprays air flow towards the axis direction of the cable 9, forming an orthogonal air flow field with the spiral air curtain. The included angle between the strip-shaped nozzle 61 and the workbench 1 is arranged to be between 30°-60°. In this embodiment, the included angle between the strip-shaped nozzle 61 and the workbench 1 is 60°, and the air injection pressure of the strip-shaped nozzle 61 is arranged to be between 0.2-0.5 MPa.

[0036] The strip-shaped nozzle 61 sprays air flow towards the cable 9, forming an air flow field around the cable 9, which points to the flow guide groove 6. On the one hand, it can prevent debris from scattering in the direction away from the cable 9; on the other hand, when the debris blown by the nozzle 5 at the grinding wheel 3 moves to the vicinity of the cable 9, the air flow generated by the strip-shaped nozzle 61 can act on the debris again, further guiding the debris into the flow guide groove 6.

[0037] The air flow sprayed by the strip-shaped nozzle 61 can form a pressure difference above the flow guide groove 6, pushing the debris to move in the flow guide groove 6. At the same time, the remaining energy of the air flow sprayed by the nozzle 5 in the air flow cover can also continue to push the debris to move in the flow guide groove 6.

[0038] The 60° included angle between the strip-shaped nozzle 61 and the ground can make the sprayed air flow better combined with the spiral air flow. This angle can make the air flow have a larger component in the horizontal direction, which can effectively push the debris swept by the spiral air flow to the direction of the debris collecting groove 7, and also has a certain component in the vertical direction, which can use gravity to assist the debris to fall, so that the debris falls into the debris collecting groove 7 more smoothly.

[0039] Referring to Figure 1 and Figure 3 , the flow guide groove 6 is arranged obliquely on the workbench 1, and the height of the flow guide groove 6 gradually decreases along the direction away from the grinding wheel 3. A notch 13 is formed in the workbench 1, and a debris collecting groove 7 is arranged in the notch 13. The debris collecting groove 7 is V-shaped, and the outlet of the flow guide groove 6 is communicated with the inlet of the debris collecting groove 7.

[0040] Under the action of the air flow and gravity, the debris in the flow guide groove 6 moves towards the debris collecting groove 7, and falls into the inlet through the outlet of the flow guide groove 6.

[0041] Referring to Figure 1 and Figure 4, the air flow control system 8 includes a vortex air compressor, an air flow regulating valve, a wind speed sensor and a PLC controller, the vortex air compressor provides a power source for the nozzles 5 and the strip nozzles 61 in the annular air cover 4, the vortex air compressor compresses the air sucked in and delivers it to the components such as the nozzles 5 and the strip nozzles 61 in the annular air cover 4 through the pipeline, so as to generate an air flow that can block the splashing of debris.

[0042] With reference to Figure 4 , the air flow regulating valve is installed on the air inlet pipeline of the annular air cover 4 and the strip nozzles 61, which facilitates the control of the air flow rate and pressure entering the annular air cover 4 and the strip nozzles 61, and realizes the best protection and debris interception effect.

[0043] With reference to Figure 4 , the wind speed sensor is installed in the annular air cover 4 and around the strip nozzles 61, which is used to monitor the speed of the air flow in real time, so as to feedback to the control system and realize accurate control of the air flow speed, and ensure that the air flow can effectively block the splashing of debris.

[0044] With reference to Figure 3 , a control panel 81 is arranged near the workbench 1, the control panel 81 integrates the air flow control valve, the wind speed sensor and the PLC controller, the PLC controller is used to control the vortex air compressor, the air flow control valve and the start-stop and motion state switching of the driving source 31, the vortex air compressor is started before the driving source 31 drives the grinding wheel 3 to rotate, and the driving source 31 is started to control the grinding wheel 3 to operate after the air flow is stable, so as to ensure that there is protective air flow in time when the grinding wheel 3 works.

[0045] Meanwhile, the PLC controller can receive real-time data of the wind speed sensor, analyze and process the data, judge whether the current air flow meets the protection requirements according to the air flow speed data fed back by the wind speed sensor, and issue corresponding control instructions to adjust the opening degree of the air flow regulating valve or the output power of the vortex air compressor, so as to maintain the stability and appropriate speed of the air flow.

[0046] The implementation principle of the detection robot for wire and cable production is that the PLC controller first issues an instruction to the vortex air compressor, the vortex air compressor runs to deliver air flow to the annular air cover 4 and the strip nozzles 61, forming an orthogonal air flow field, and then the driving source 31 is started to drive the grinding wheel 3 to rotate, while the grinding wheel 3 rotates, the two sliding seats 22 synchronously reciprocate on the corresponding linear guide rails 21, driving the wire and cable 9 to dynamically rub against the grinding wheel 3, simulating the continuous sliding friction of the wire and cable 9.

[0047] The cable 9 will generate debris during the friction with the grinding wheel 3, and the heat generated by the friction will easily melt the debris and adhere it to the surface of the grinding wheel 3. When the airflow is ejected from the nozzle 5, it will first reduce the temperature of the surface of the grinding wheel 3, and secondly, the airflow will form a spiral airflow around the outer periphery of the grinding wheel 3, which will concentrate the debris ground from the grinding wheel 3 inside the air curtain, so that the debris will not be randomly scattered around, but will be more concentratedly moved away from the cable 9 under the constraint of the spiral air curtain. At the same time, the strip-shaped nozzle 61 sprays the airflow towards the cable 9, which will form an airflow field around the cable 9 pointing to the guide groove 6. On the one hand, it can prevent the debris from scattering in the direction away from the cable 9; on the other hand, when the debris blown by the nozzle 5 at the grinding wheel 3 moves to the vicinity of the cable 9, the airflow generated by the strip-shaped nozzle 61 can act on it again, further guiding the debris into the guide groove 6.

[0048] The airflow sprayed by the strip-shaped nozzle 61 will form a pressure difference above the guide groove 6, which will push the debris to move in the guide groove 6. At the same time, the airflow sprayed by the nozzle 5 in the airflow cover can continue to push the debris to move forward in the guide groove 6 during the process of guiding the debris into the guide groove 6.

[0049] The debris in the guide groove 6 will be affected by the gravity and the pushing force of the airflow, and can move towards the direction of the debris collecting groove 7 and fall into the debris collecting groove 7, so as to complete the collection of the debris.

[0050] The embodiments of the specific embodiment are the preferred embodiments of the present application, and are not limited to the protection scope of the present application, wherein the same parts are indicated by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
