Description

Technical Field

[0001] The invention relates to the technical field of rubber layer testing, in particular to a rubber layer testing device for wire harness manufacturing. Background Art

[0002] In the actual manufacturing of electronic communication accessories, a large number of electronic communication equipment need to rely on wiring harnesses for power or signal transmission. Wire harnesses usually use a molded rubber layer on the outside of the conductor. The molding quality of this rubber layer directly affects the corrosion resistance and other properties of the wire harness. The current rubber layer testing device for wire harness manufacturing is not convenient for rubber layer winding testing. For wire harnesses with smaller diameters, traditional laser measurement and other methods have large deviations. It is not convenient to directly perform circumference testing on the outer periphery of the wire harness. At the same time, it is not convenient to fully understand the molding flatness of the wire harness's rubber layer, which is easy to cause missed detection. At the same time, it is not convenient to test the strength of the wire harness's surface rubber layer. It is not convenient to prompt in time when cracks occur. Relying on manual inspection of the rubber layer quality is time-consuming and labor-intensive. At the same time, there are also some blister tests to test the cracking of the rubber layer. The disadvantage is that the rubber layer at the crack is easy to close and difficult to penetrate, resulting in missed detection. At the same time, it is not convenient to test the adhesion of the cable rubber layer, affecting the subsequent service life.

[0017] The conveying and pulling adjustment can be used to test the firmness of the wire harness's adhesive layer to avoid poor adhesion between the adhesive layer and the internal wires, which affects the service life. The wire harness is a key component in the electrical system, and its external rubber mainly insulates and protects the internal wires. If the adhesion between the rubber and the wires is poor, it will first directly affect the insulation performance of the wire harness, and the adhesive layer will be more easily worn, causing a short circuit.

[0018] Bending conveying parts can be used to bend and convey wire harnesses. Two sets of bending conveying parts can be used to bend the wire harnesses at different angles, up, down, left and right. This can avoid problems such as cracks on the surface of the wire harness. Due to the elasticity of the glue layer itself, the conductive liquid does not penetrate into the through holes for storing liquid on the support mounting block to cause missed detection, thereby further ensuring the comprehensiveness of the detection.

[0033] Among them, the installation support member 1 further includes: support feet 1011, indicator lights 102, suction pipes 103 and closing bolts 104. Two support feet 1011 are fixedly installed on the support mounting block 101, and through holes are respectively provided on the two support feet 1011; two indicator lights 102 are fixedly installed on the support mounting block 101; a suction pipe 103 is fixedly installed on the top of the support mounting block 101; a valve is provided on the suction pipe 103, and the suction pipe 103 communicates with the through hole on the support mounting block 101; a closing bolt 104 is threadedly connected to the support mounting block 101; the closing bolt 104 is used to close the through hole on the support mounting block 101; the two limit levers 1012, the indicator lights 102 and the end of the wire harness are connected in series to the power supply; the sleeve rope connector 2 includes: sleeve rope shafts 201, full-wrap sleeve ropes 2011 and sliding columns 202. There are two sleeve rope shafts 201, and the two sleeve rope shafts 201 are respectively slidably installed on the support mounting block 101; a full-wrap sleeve rope 2011 is fixedly installed between the two sleeve rope shafts 201, and the full-wrap sleeve rope 2011 is used to wind around the outside of the wire harness for one circle; sliding columns 202 are respectively fixedly installed at the tails of the two sleeve rope shafts 201; rectangular through grooves are respectively formed on the two sliding columns 202; grooves are respectively provided at the ends of the two limit levers 1012, and the winding position of the full-wrap sleeve rope 2011 on the outside of the wire harness is located in the grooves at the ends of the two limit levers 1012; the pressure control prompt member 3 includes: a test fixing block 301, a test spring 3011 and a detection extrusion column 3012.

The SBT732 type pressure sensor 302 can be used, and a supporting display is adopted. The pressure sensor 302 is fixedly installed at the end of the detection extrusion column 3012; the end of the pressure sensor 302 is adhesively connected to the inner side of the rectangular through groove formed on the sliding column 202;The pressure sensor 302 is externally connected to a display, and the pressure control prompt piece 3 can be used in conjunction with the rope connector 2 to realize comprehensive testing by wrapping around the surface of the wire harness. When there are abnormal protrusions or depressions on the surface of the wire harness, or hollows between the rubber layer and the wire, testing can be performed. The full-cover rope 2011 can be used to ensure comprehensive testing and avoid omissions. At the same time, the structure can be tested in real time, and the full-cover rope 2011 can be used for testing, which is more suitable for testing wire harnesses with smaller diameters. It can avoid the small range of traditional clamps and other measurement methods, which are difficult to ensure the external detection of the wire harness. The circumference is completely fitted to the test, and it is not convenient to test the small diameter wire harness, because the test spring 3011 can push the pressure sensor 302 to squeeze the sliding column 202 in real time, and the full-cover rope 2011 is tightened at this time. Once the wire harness has abnormal protrusions, depressions, or hollows between the glue layer and the wire during movement, the full-cover rope 2011 will adapt to the changing circumference of the wire harness, and the full-cover rope 2011 will also pull the rope shaft 201. At this time, the degree of compression of the test spring 3011 will change, and the pressure sensor 302 can be used for real-time detection. ;

[0034] Among them, the sealed conveying member 4 includes: a sealing cover 401 and a wire harness sealing ring 402. There are two sealing covers 401, and the two sealing covers 401 are respectively threadedly connected to both sides of the support mounting block 101; a wire harness sealing ring 402 is fixedly installed on the sealing cover 401, and a through hole is provided in the middle of the wire harness sealing ring 402; the middle of the wire harness sealing ring 402 is used for passing the wire harness; the sealing cover 401 is used to seal the through hole on the support mounting block 101; the conveying traction adjustment 5 includes: a motor arm 501 and a driving wheel 502. There are two motor arms 501, and the two motor arms 501 are respectively fixedly installed on the support mounting block 101 by bolts; driving wheels 502 are respectively rotatably installed on the two motor arms 501; an annular groove is provided on the outer side of the driving wheel 502; the two driving wheels 502 are used for rolling and conveying the wire harness; the conveying traction adjustment 5 further includes: a driving motor 503, and driving motors 503 are respectively fixedly installed on the two motor arms 501; the output shafts of the two driving motors 503 are respectively fixedly installed at the ends of the two driving wheels 502. The conveying traction adjustment 5 can be used to test the firmness of the glue layer of the wire harness, avoiding the poor adhesion effect between the glue layer and the internal wire and affecting the service life. As a key component in the electrical system, the external rubber skin of the wire harness mainly plays the role of insulation and protecting the internal wire. If the adhesion effect between the rubber skin and the wire is poor, it will first directly affect the insulation performance of the wire harness. At the same time, the glue layer is also more likely to be worn, leading to short-circuit problems. Short circuits will not only cause damage to electrical equipment, but may also cause safety hazards such as fires, and will also reduce the service life of the wire harness. This structure can use the conveying traction adjustment 5 to detect in real time, and at the same time, the insulation of the glue layer of the wire harness can be tested through the sealed conveying member 4, which can further ensure the quality of the wire harness detection. Because the wire harness is continuously moving, under the action of friction, the full-wrap rope 2011 can be pulled to one side, and the groove length provided at the end of the limit lever 1012 is greater than the diameter of the full-wrap rope 2011. Once the adhesion between the glue layer of the wire harness and the internal wire is poor, because the glue layer has elasticity, a separation position of the glue layer will cause the driving wheel 502 to drive the glue layer to move and convey, while the moving speed of the internal wire decreases. At this time, the moving speed of the wire harness will be significantly reduced, and then the friction driving speed of the full-wrap rope 2011 will be significantly reduced, and the displacement of the friction force pulling the full-wrap rope 2011 to one side will be reduced. It can be detected in real time through the pressure sensor 302. At the same time, during this process, the limit lever 1012 discharges in real time. Once the glue layer of the wire harness is damaged, the conductive liquid that seeps into the liquid-storing through hole on the support mounting block 101 will cause the series circuit of the indicator light 102 to be turned on, and the light will be on to give a prompt.

[0035] Embodiment 2. On the basis of Embodiment 1, the bending conveyor 6 includes: a bending conveyor arm 601 and a concentric collar 602. There are two bending conveyor arms 601 in total, and the two bending conveyor arms 601 are respectively fixedly installed on the two sealing covers 401; the structures on the two bending conveyor arms 601 are the same; the two bending conveyor arms 601 are offset by ninety degrees; two concentric collars 602 are fixedly installed on the bending conveyor arm 601; the two concentric collars 602 are concentric with the wire harness sealing ring 402; the two concentric collars 602 are used for the wire harness to pass through; the bending conveyor 6 further includes: a sliding shaft 603, a tension spring 604 and a pushing block 605. The sliding shaft 603 is slidably inserted into the bending conveyor arm 601; the tension spring 604 is sleeved on the sliding shaft 603, and the end of the tension spring 604 is connected to the tail of the sliding shaft 603; the other end of the tension spring 604 is connected to the inner side of the bending conveyor arm 601; the end of the sliding shaft 603 is fixedly installed with the pushing block 605; the pushing block 605 is provided with a groove; the pushing block 605 is used to push the wire harness to bend. The bending conveyor 6 can be used to bend and convey the wire harness. Two sets of bending conveyors 6 can be used to bend the wire harness at different angles in the up, down, left and right directions, which can avoid problems such as cracks on the surface of the wire harness. Under the elastic action of the glue layer itself, the conductive liquid that does not penetrate into the liquid storage through hole on the support mounting block 101 will not cause the problem of missed detection, further ensuring the comprehensiveness of detection. This structure is simple and will not damage the wire harness, and can ensure the detection accuracy. The two sliding shafts 603 can respectively drive the pushing block 605 to push the wire harness under the pulling of the tension spring 604 to bend the wire harness, so that the cracks on its surface can crack and penetrate the conductive liquid to ensure the smooth detection of this structure, and the structure is more reasonable.

[0036] Working principle of this embodiment: First, the support feet 1011 are installed in front of the discharge port of the wire harness rubber layer forming machine through bolts. The driving motor 503 drives the driving wheel 502 to rotate. The wire harness can pass through the wire harness sealing ring 402, the concentric sleeve 602 and between the two driving wheels 502. The driving wheel 502 clamps the outer side of the rubber layer of the wire harness to traction the wire harness to move. During the process, because the wire harness is continuously moving, under the action of friction, the full-wrap rope 2011 can be pulled to one side. And the groove length at the end of the limit lever 1012 is greater than the diameter of the full-wrap rope 2011. Once the bonding firmness between the rubber layer of the wire harness and the internal wire is poor, because the rubber layer has elasticity, the position where the rubber layer is separated will cause the driving wheel 502 to drive the rubber layer to move and convey, while the moving speed of the internal wire decreases. At this time, the moving speed of the wire harness will be significantly reduced, and then the friction driving speed of the full-wrap rope 2011 to one side will be significantly reduced, and the displacement of the friction force pulling the full-wrap rope 2011 to one side will be reduced. It can be detected in real time through the pressure sensor 302. At the same time, during this process, the limit lever 1012 discharges electricity in real time. Once the wire harness rubber layer is damaged, the conductive liquid that penetrates into the liquid storage through hole on the support mounting block 101, at this time, the series circuit of the indicator light 102 will be turned on and the light will be on to give a prompt. During the movement of the wire harness, the limit lever 1012 is used to limit the full-wrap rope 2011 at the wire harness winding place, which can improve the stability of the full-wrap rope 2011. Because the test spring 3011 can push the pressure sensor 302 to squeeze the sliding column 202 in real time, at this time the full-wrap rope 2011 is tightened. Once there are abnormal protrusions, depressions or air pockets between the rubber layer and the wire during the movement of the wire harness, at this time the full-wrap rope 2011 will adapt to the changed circumference of the wire harness, and the full-wrap rope 2011 will pull the rope shaft 201. At this time, the degree of compression of the test spring 3011 will change, and it can be detected in real time through the pressure sensor 302 and read in real time through an external display. The suction pipe 103 is connected to the suction pump to pump air in real time, which can reduce the bubbles in the conductive liquid in the liquid storage through hole on the support mounting block 101, facilitating the penetration of the conductive liquid. During the conveying of the wire harness, the two sliding shafts 603 can drive the pushing block 605 to push the wire harness under the pulling of the tension spring 604 respectively, bending the wire harness to facilitate the penetration of the conductive liquid into cracks and the like on its surface, ensuring the smooth detection of this structure.
