Description

Technical Field

[0001] The invention relates to the technical field of wire harness production, and in particular to a wire harness detection machine. Background Art

[0002] The wiring harness is a wiring component that connects electrical equipment in a circuit. It is mainly composed of wires, insulating sheaths, wiring terminals, etc. It has a simple structure and low manufacturing cost. During the production process of the wiring harness, the produced wiring harness needs to be tested. The wiring terminals at both ends of the wiring harness are inserted into the detection circuit inside the detection machine for wire-through detection. After the test is qualified, the qualified wiring harness surface will be coded and marked, and the production of the wiring harness is finally completed; During the inspection of the wire harness, the work needs to be based on the actual working situation, and the wiring terminals of the wire harness can be inserted into the junction box. The operation is simple, but in the actual inspection process, the traditional inspection machine can only complete the electrical measurement effect of the wire harness, and it is necessary to use manual methods for secondary inspection later to detect the connection between the wiring terminals and the insulating sheath in the wire harness and the bending strength of the insulating sheath in the wire harness. The overall operation is relatively cumbersome, and the accuracy of the inspection results is general when the manual method is used to inspect the bending strength of the insulating sheath in the wire harness. When the manual method is used to inspect the bending strength of the insulating sheath in the wire harness, it is mainly bent manually, and the bending force cannot be well controlled by the manual method. If the bending force is too large, it is likely to cause damage to the wire harness. If the bending force is too small, the inspection effect is general. Therefore, a wire harness inspection machine is provided. Summary of the invention

DETAILED DESCRIPTION

[0015] See also Figure 1-Figure 18A wire harness inspection machine comprises a frame 1, a display screen 2 is fixedly installed on the outer side of the frame 1, an LED lamp 3 is fixedly installed in the frame 1, a tricolor lamp 4 is also fixedly installed in the frame 1, a laser coder 5 is fixedly installed in the frame 1, a smoke purifier 6 is also fixedly installed in the frame 1, a plurality of panel boxes 8 are installed in the frame 1, a sealing plate 7 is fixedly connected to the upper side of each panel box 8, two mounting holes 9 are opened on the upper side of the sealing plate 7, and two conductive rods 10 are fixedly installed in each panel box 8, and the two conductive rods 10 are opposite to the mounting holes 9; First, two conductive rods 10 are fixedly installed in each panel box 8, and conductive holes are opened at the upper ends of the two conductive rods 10. When the wiring harness is detected, the wiring terminal of the wiring harness can be inserted into the conductive hole. Secondly, the two conductive rods 10 in each panel box 8 are in an open circuit state. The wiring harness is inserted into different conductive rods 10 for measurement. The fundamental principle is to change the resistance value of the measuring resistor to simulate different working conditions. Then, the laser coding equipment is also called laser inkjet printer or laser coding machine 5. It is a device used for laser coding. The equipment is divided into two types: engraving type and dot matrix type. The material on its surface is vaporized by burning and etching, and the pattern or text is accurately engraved by controlling the effective displacement of the laser beam. The smoke purifier 6 is a machine used to remove smoke, dust and harmful gases from the air. It can effectively improve the air quality through high-efficiency filtration and adsorption technology. When the laser coding machine 5 is working, the smoke generated by the laser coding machine 5 can be absorbed by the smoke purifier 6. Secondly, the wiring harness is mainly composed of three parts: a wire, an insulating sheath, and a terminal. When the wiring harness needs to be inspected, the wiring harness to be inspected passes through the mounting hole 9 and is finally inserted into the conductive rod 10 in the panel box 8. Then, the power-on operation is started through the display screen 2, and then the electrical inspection operation of the wiring harness is started. During the inspection process, the LED light 3 and the three-color light 4 can be turned on, so that the staff can more clearly see whether there are defects on the surface of the wiring harness. If the wiring harness does not have any defects, the wiring harness can be moved to the lower side of the laser coding machine 5, and the laser coding machine 5 is started while the smoke purifier 6 is started to code the insulating sheath on the surface of the wiring harness, and finally the inspection operation of the wiring harness is completed. The above are all prior arts and no unnecessary elaboration is made. like Figure 3 , Figure 4 , Figure 5 , Figure 8, each panel box 8 is installed with a clamping assembly 1, and the clamping assembly 1 includes four arc-shaped plates 123. Four clamping plates 14 are fixedly installed in the panel box 8. The side walls of each clamping plate 14 are rotatably connected with a threaded cylinder 20. Each threaded cylinder 20 is threadedly connected with a threaded rod 21. The outer side of the threaded rod 21 is fixedly connected with a control frame 26. The lower side of the control frame 26 is fixedly connected with a slide plate 22. The slide plate 22 and the panel box 8 are slidably connected. A slider 30 is slidably connected in the control frame 26. The arc-shaped plate 123 and the slider 30 are fixedly connected. The outer side of the slider 30 is fixedly connected with a connecting plate 21. A spring 32 is fixedly connected between the connecting plate 21 and the control frame 26. A dual-axis motor 11 is also fixedly connected in the panel box 8. The output shaft of the dual-axis motor 11 is transmission-connected to the threaded cylinder 20 through a pulley assembly 12. An anti-skid rubber pad is fixedly connected to the inner side of the arc-shaped plate 123. Under the action of the anti-skid rubber pad, a better clamping effect on the end of the wiring harness can be formed; First, when the end of the wire harness is inserted into the conductive rod 10, the dual-axis motor 11 is started, and the output shaft of the dual-axis motor 11 drives the threaded cylinder 20 to rotate through the pulley assembly 12. Since the threaded cylinder 20 and the threaded rod 21 are threadedly connected, and the control frame 26 fixedly connected to the threaded rod 21 is slidably connected to the slide plate 22 and the panel box 8, Figure 4 From the perspective of , the threaded rods 21 on the front and rear sides rotate in opposite directions. Therefore, when the rotation directions of the threaded cylinder 20 are the same, the threaded rods 21, the slide plate 22, and the control frame 26 will move towards or away from each other. The movement direction can be adjusted by controlling the rotation direction of the output shaft of the dual-axis motor 11. After the end of the wiring harness is inserted into the conductive rod 10, the threaded rods 21 and the control frame 26 on the front and rear sides relative to each other can be moved towards each other. The control frame 26 drives the slider 30 to move through the spring 1 32 and the connecting plate 2 31, and the slider 30 drives the arc plate 1 23 to move until the arc plate 1 23 and the end of the wiring harness are against each other and the spring 1 32 is in a compressed state, thereby completing the clamping and fixing operation of the end of the wiring harness.

[0016] like Fig.13 , Fig.14 , Fig.15 The clamping assembly 2 includes four arc plates 24, and the positions of the four arc plates 24 are opposite to the arc plate 1 23. The side wall of the control frame 26 is fixedly connected with a connecting rod 1 29, and the side wall of the connecting rod 1 29 is fixedly connected with a moving plate 28. The side wall of the moving plate 28 is fixedly connected with a connecting rod 5 51, and the outer side of the connecting rod 5 51 is slidably connected with a mounting cylinder 53, and a spring 3 52 is fixedly connected between the mounting cylinder 53 and the connecting rod 5 51. The side wall of the mounting cylinder 53 is fixedly connected with a moving frame 25, and a round rod 27 is slidably connected in the moving frame 25. The round rod 27 is slidably connected with a sliding rod 62, the arc plate 24 and the sliding rod 62 are fixedly connected, and a control assembly for controlling the movement of the round rod 27 is installed in the control frame 26; First, during the movement of the control frame 26, the control frame 26 drives the moving plate 28 and the connecting rod five 51 to move through the connecting rod one 29, the connecting rod five 51 drives the installation tube 53 and the moving frame 25 to move through the spring three 52, the moving frame 25 drives the round rod 27 to move, and the round rod 27 drives the arc plate two 24 to move through the slide bar 62 (the structure and principle that the round rod 27 can drive the arc plate two 24 to move through the slide bar 62 are described later), the arc plate two 24 and the wiring harness are against each other to form a clamping effect on the insulating sheath, which is different from the clamping effect formed by the arc plate one 23. The arc plate one 23 is located at the end of the wiring harness and is against the wiring terminal. The diameter of the wiring terminal is much larger than that of the insulating sheath. Therefore, when the spring one 32 begins to be compressed, the arc plate two 24 has not yet been against the insulating sheath. After the threaded rod 21, the slide plate 22 and the control frame 26 continue to move for a distance, the arc plate two 24 will be against the insulating sheath, and the spring three 52 will begin to be compressed.

[0017] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.15 , Fig.16 The control assembly includes a moving cylinder 33 slidably installed in the control frame 26, a square rod 34 is slidably connected in the moving cylinder 33, a control rod 66 is fixedly connected to the outer side of the square rod 34, two slide grooves 37 are opened in the control frame 26, one end of the control rod 66 extends into the slide groove 37 and is slidably connected to the slide groove 37, a connecting rod 2 38 is fixedly connected to the upper side of the square rod 34, a connecting rod 3 39 is fixedly connected to the side wall of the connecting rod 2 38, two fixed plates 35 are symmetrically fixedly connected to the upper side of the control frame 26, a rotating rod 36 is rotatably connected between the two fixed plates 35, a gear 1 40 is rotatably connected to the outer side of the rotating rod 36, a rack 1 43 is fixedly connected to the side wall of the moving cylinder 33, the rack 1 43 is meshed with the gear 1 40, the outer side of the rotating rod 36 is rotatably connected to the gear 2 41, the gear 2 A torsion spring 44 is fixedly connected between 41 and gear one 40, a connecting cylinder 45 is fixedly connected to the outer side of gear two 41, a ratchet 42 is fixedly connected to the outer side of the connecting cylinder 45, a control cylinder 46 is slidably connected to the upper side of the control frame 26, the control cylinder 46 is fixedly connected to the connecting rod three 39, a connecting rod four 47 is slidably connected inside the control cylinder 46, a spring two 49 is fixedly connected between the connecting rod four 47 and the control cylinder 46, a baffle 48 is fixedly connected to the upper side of the connecting rod four 47, a rack two 54 is slidably connected to the side wall of the control frame 26, the rack two 54 is meshed with the gear two 41, a connecting rod six 55 is fixedly connected to the upper side of the rack two 54, a connecting rod eight 65 is slidably connected to the outer side of the connecting rod six 55, a collar 56 is fixedly connected to the outer side of the connecting rod eight 65, and the collar 56 is fixedly connected to the round rod 27; First, when the control frame 26 drives the slider 30 to move through the spring 1 32 and the connecting plate 2 31, the arc plate 1 23 has not yet abutted against the terminal. When the arc plate 1 23 abuts against the terminal, the arc plate 1 23 stops moving due to the obstruction of the terminal. However, at this time, the control frame 26 is still in a moving state, so the spring 1 32 is compressed. At this time, the control frame 26 moves relative to the arc plate 1 23. Figure 8 From the perspective of FIG. 2 , the control frame 26 moves rightward relative to the slider 30 and the moving cylinder 33. Since the rack 1 43 is fixedly connected to the moving cylinder 33, the gear 1 40 meshing with the rack 1 43 rotates clockwise. The gear 1 40 drives the gear 2 41 to rotate clockwise through the torsion spring 44. The gear 2 41 drives the ratchet 42 to rotate clockwise through the connecting cylinder 45. At the same time, Fig. 9 4 and 49. From the perspective of FIG. 3 , the slide slot 37 is composed of two parts, namely an inclined part and a transverse part. In the initial state, the control rod 66 is located at the end of the inclined part on the right side of the slide slot 37. Under the action of the slide slot 37 and the control rod 66, the square rod 34 will move upward relative to the moving cylinder 33. The square rod 34 drives the control cylinder 46 to move upward through the connecting rod 2 38 and the connecting rod 39. The control cylinder 46 drives the connecting rod 47 and the baffle plate 48 to move upward through the spring 2 49. When the control rod 66 is about to move to the transverse part of the slide slot 37, the baffle plate 48 will resist the ratchet 42, forming an obstruction effect on the ratchet 42, so that the ratchet 42 cannot rotate with the gear 1 40, and the torsion spring 44 begins to deform. In the process of the control frame 26 continuing to move, when the control rod 66 moves from the transverse part to the oblique downward part, the baffle plate 48 and the ratchet 42 are disconnected, and the ratchet 42 loses its restriction. At this time, under the dual action of the gear 1 40 and the torsion spring 44, the gear 2 41 and The ratchet 42 rotates clockwise rapidly, and the gear 2 41 drives the rack 2 54 to move upward. The rack 2 54 drives the connecting rod 8 65 to move upward through the connecting rod 6 55. The connecting rod 8 65 drives the round rod 27 to move upward through the ring 56. The round rod 27 drives the arc plate 24 to move upward through the slide bar 62. Since the arc plate 24 and the insulating sheath are in a state of abutment, the arc plate 24 will cause the insulating sheath to move upward relative to the terminal. After the electrical measurement operation of the wiring harness is completed, especially after the end of the wiring harness is taken out of the panel box 8, when the staff inspects the surface of the wiring harness, the connection between the insulating sheath and the terminal can be viewed at the same time. If there is no abnormality in the connection between the insulating sheath and the terminal, it means that the connection effect between the insulating sheath and the terminal is good. In the above process, there is no need to pull the wiring harness manually, and a mechanical method is used for pulling. The pulling force each time is small, which can greatly reduce the error and maintain the accuracy of the experimental results.

[0018] like Fig.13 , Fig.16 A bending assembly for bending the wire harness is installed in the moving frame 25, and the bending assembly includes a connecting ball 63 fixedly installed on the outside of the sliding rod 62. A plurality of protrusions 50 are evenly fixedly installed in the control frame 26. A spring 4 57 is fixedly connected between the arc plate 24 and the round rod 27. A pressure sensor 58 is also fixedly connected between the arc plate 24 and the round rod 27. The surfaces of the connecting ball 63 and the protrusion 50 are both smooth. First, the pressure sensor 58 is a component that can sense pressure signals and convert the pressure signals into electrical signals. Second, the protrusions 50 in the two relative control frames 26 are distributed as follows: Fig.18 As shown, in Fig.18 In the figure, the middle part represents the wire harness, the dotted line represents the motion trajectory of the arc plate 24 on both sides of the wire harness, and Fig.18 It can be seen that the protrusions 50 in the control frames 26 on both sides are in a staggered arrangement, and only when the connection ball 63 on one side is disconnected from the protrusion 50, the connection ball 63 on the other side will abut against the protrusion 50. When the connection ball 63 and the protrusions 50 on both sides are not abutted, the spring four 57 and the spring three 52 are both in a compressed state, and according to Newton's second law, Figure 5 From the perspective of , the sum of the forces of the spring four 57 and the spring three 52 on the left side is equal to the sum of the forces of the spring four 57 and the spring three 52 on the right side. When the connecting ball 63 and the protrusion 50 are offset, the deformation of the spring four 57 on the same side will change, and then the force will change, which will eventually cause the arc plate two 24 and the wire harness to move laterally, causing the wire harness to bend, until the connecting ball 63 and the protrusion 50 are disconnected, and the forces on both sides are equal again. Finally, in the process of the arc plate two 24 moving upward, the wire harness is bent back and forth, providing a basis for the subsequent detection of the insulating sheath, without the need for manual bending; And in the above working process, when the connecting ball 63 is not in contact with the protrusion 50, the pressure sensor 58 has already sent out an electrical signal. After the connecting ball 63 and the protrusion 50 are in contact with each other, the electrical signal sent out by the pressure sensor 58 changes. The amplitude of the change of the pressure sensors 58 on both sides can be compared. If the amplitude of the change of the pressure sensor 58 is small, it means that the insulating sheath of the wiring harness is softer. If the amplitude of the change of the pressure sensor 58 is large, it means that the insulating sheath of the wiring harness is harder, thereby forming a simple detection effect of the hardness of the insulating sheath of the wiring harness.

[0019] like Fig.16 , Fig.17A detection component for detecting whether there are defects on the surface of the wiring harness is installed on the outer side of the arc plate 24, and the detection component includes a connecting rod 7 60 rotatably installed at both ends of the arc plate 24, and the outer sides of the two connecting rods 7 60 are fixedly connected with a clamping cylinder 61, and the outer sides of the two connecting rods 7 60 are also fixedly connected with a fixing ring 16, and the outer side of the fixing ring 16 is rotatably connected with a rotating ring 18, and the outer side of the fixing ring 16 is fixedly connected with a connecting plate 3 17, and a spring 5 19 is fixedly connected between the connecting plate 3 17 and the rotating ring 18, and a torque sensor is fixedly connected between the fixed ring 16 and the rotating ring 18, and the outer side of the rotating ring 18 is fixedly connected with a connecting rod 15, and the outer side of the connecting rod 15 is fixedly connected with a connecting rod 9 13, and the outer side of the connecting rod 9 13 is rotatably connected with a connecting block 59, and the outer side of the connecting block 59 is fixedly connected with a telescopic rod 64, and one end of the telescopic rod 64 is hinged to the round rod 27; First, the torque sensor can convert the physical change of torque into an accurate electrical signal. When the connecting ball 63 and the protrusion 50 are against each other, the arc plate 24 will move relative to the round rod 27. The round rod 27, the telescopic rod 64, the connecting block 59, and the arc plate 24 can be approximately regarded as an isosceles trapezoid. Since the arc plate 24 will move back and forth relative to the round rod 27, the angle formed by the connecting block 59 and the arc plate 24 will change, which will cause the rotating ring 18 to rotate relative to the fixed ring 16. However, since the clamping tube 61 and the insulating sheath are against each other, the clamping tube 61 will not rotate under the obstruction of the insulating sheath, which will cause the spring 5 19 to deform, and the torque sensor will send out a corresponding electrical signal. In this process, if there is no defect on the surface of the insulating sheath, the electrical signals sent by the torque sensors on both sides are the same. If there are certain defects on the surface of the insulating sheath, the friction force on the surface of the insulating sheath will be different, and the electrical signals sent by the torque sensors on both sides will be different, thereby forming a simple detection effect on the surface of the insulating sheath. It should be emphasized here that when the arc plate 1 23 and the terminal block are against each other, there is still a certain distance between the arc plate 24 and the insulating sheath. When the square rod 34 starts to move upward relative to the moving cylinder 33, the baffle 48 will not form an obstruction effect on the ratchet 42. At this time, the connecting rod 6 55 can be driven to move upward under the action of the gear 1 40, the rack 1 43, the torsion spring 44, the gear 2 41, and the rack 2 54. The connecting rod 6 55 drives the round rod 27 to move upward through the connecting rod 8 65 and the ring 56, and the round rod 27 drives the arc plate 24 to move upward through the sliding rod 62. And the rotating ring 18 can be driven to rotate under the action of the connecting ball 63, the protrusion 50 and the spring four 57. The rotating ring 18 drives the clamping tube 61 to rotate through the spring five 19, the connecting plate three 17, the fixed ring 16 and the connecting rod seven 60. However, at this time, the clamping tube 61 and the arc plate two 24 are not against the insulating sheath. Until the baffle 48 can form an obstruction effect on the ratchet 42, the clamping tube 61 and the arc plate two 24 will not be against the insulating sheath. Therefore, when the arc plate one 23 just abuts against the terminal, the clamping tube 61 and the arc plate two 24 will not have any impact on the insulating sheath.

[0020] In the present invention, when it is necessary to perform a detection operation on the wiring harness, the wiring harness to be detected is passed through the mounting hole 9 and finally inserted into the conductive rod 10 in the panel box 8, and then the power-on operation is started through the display screen 2, and then the electrical detection operation of the wiring harness is started. During the detection process, the LED light 3 and the three-color light 4 can be turned on, so that the staff can more clearly see whether there are defects on the surface of the wiring harness. If the wiring harness does not have any defects, the wiring harness can be moved to the lower side of the laser coding machine 5, and the smoke purification machine 6 is started at the same time as the laser coding machine 5, and the insulating sheath on the surface of the wiring harness is coded, and finally the detection operation of the wiring harness is completed. The above are all prior arts and no unnecessary elaboration is made; When the end of the wire harness is inserted into the conductive rod 10, the double-axis motor 11 is started, and the output shaft of the double-axis motor 11 drives the threaded barrel 20 to rotate through the pulley assembly 12. Since the threaded barrel 20 and the threaded rod 21 are threadedly connected, and the control frame 26 fixedly connected to the threaded rod 21 is slidably connected to the slide plate 22 and the panel box 8, Figure 4From the perspective of , the threaded rods 21 on the front and rear sides rotate in opposite directions. Therefore, when the rotation directions of the threaded cylinder 20 are the same, the threaded rods 21, the slide plate 22, and the control frame 26 will move towards or away from each other. The moving direction can be adjusted by controlling the rotation direction of the output shaft of the dual-axis motor 11. After the end of the wiring harness is inserted into the conductive rod 10, the threaded rods 21 and the control frame 26 on the front and rear sides that are opposite to each other can be moved towards each other. The control frame 26 drives the slide block 30 to move through the spring 1 32 and the connecting plate 2 31, and the slide block 30 drives the arc plate 1 23 to move until the arc plate 1 23 and the end of the wiring harness are against each other and the spring 1 32 is in a compressed state, thereby completing the clamping and fixing operation of the end of the wiring harness; During the movement of the control frame 26, the control frame 26 drives the moving plate 28 and the connecting rod 51 to move through the connecting rod 1 29, the connecting rod 51 drives the installation cylinder 53 and the moving frame 25 to move through the spring 3 52, the moving frame 25 drives the round rod 27 to move, the round rod 27 drives the arc plate 24 to move through the slide bar 62 (the structure and principle that the round rod 27 can drive the arc plate 24 to move through the slide bar 62 are described later), the arc plate 24 and the wiring harness are against each other to form a clamping effect on the insulating sheath, which is different from the clamping effect formed by the arc plate 1 23. The arc plate 1 23 is located at the end of the wiring harness and against the wiring terminal. The diameter of the wiring terminal is much larger than that of the insulating sheath. Therefore, when the spring 1 32 begins to be compressed, the arc plate 24 has not yet been against the insulating sheath. After the threaded rod 21, the slide plate 22 and the control frame 26 continue to move for a distance, the arc plate 24 will be against the insulating sheath, and the spring 3 52 begins to be compressed; When the control frame 26 drives the slider 30 to move through the spring 1 32 and the connecting plate 2 31, the arc plate 1 23 has not yet abutted against the terminal. When the arc plate 1 23 abuts against the terminal, the arc plate 1 23 stops moving due to the obstruction of the terminal. However, the control frame 26 is still in a moving state, so the spring 1 32 is compressed. At this time, the control frame 26 moves relative to the arc plate 1 23 to Figure 8 From the perspective of FIG. 2 , the control frame 26 moves rightward relative to the slider 30 and the moving cylinder 33. Since the rack 1 43 is fixedly connected to the moving cylinder 33, the gear 1 40 meshing with the rack 1 43 rotates clockwise. The gear 1 40 drives the gear 2 41 to rotate clockwise through the torsion spring 44. The gear 2 41 drives the ratchet 42 to rotate clockwise through the connecting cylinder 45. At the same time, Fig. 94 and 49. From the perspective of FIG. 3 , the slide slot 37 is composed of two parts, namely an inclined part and a transverse part. In the initial state, the control rod 66 is located at the end of the inclined part on the right side of the slide slot 37. Under the action of the slide slot 37 and the control rod 66, the square rod 34 will move upward relative to the moving cylinder 33. The square rod 34 drives the control cylinder 46 to move upward through the connecting rod 2 38 and the connecting rod 39. The control cylinder 46 drives the connecting rod 47 and the baffle plate 48 to move upward through the spring 2 49. When the control rod 66 is about to move to the transverse part of the slide slot 37, the baffle plate 48 will resist the ratchet 42, forming an obstruction effect on the ratchet 42, so that the ratchet 42 cannot rotate with the gear 1 40, and the torsion spring 44 begins to deform. In the process of the control frame 26 continuing to move, when the control rod 66 moves from the transverse part to the oblique downward part, the baffle plate 48 and the ratchet 42 are disconnected, and the ratchet 42 loses its restriction. At this time, under the dual action of the gear 1 40 and the torsion spring 44, the gear 2 41 and The ratchet 42 rotates clockwise quickly, and the gear 2 41 drives the rack 2 54 to move upward. The rack 2 54 drives the connecting rod 8 65 to move upward through the connecting rod 6 55. The connecting rod 8 65 drives the round rod 27 to move upward through the ring 56. The round rod 27 drives the arc plate 24 to move upward through the slide bar 62. Since the arc plate 24 and the insulating sheath are in a state of abutment, the arc plate 24 will make the insulating sheath move upward relative to the terminal. After the electrical measurement operation of the wiring harness is completed, especially after the end of the wiring harness is taken out of the panel box 8, when the staff inspects the surface of the wiring harness, they can also observe the connection between the insulating sheath and the terminal. If there is no abnormality in the connection between the insulating sheath and the terminal, it means that the connection effect between the insulating sheath and the terminal is good. In the above process, there is no need to pull the wiring harness manually, and it is pulled mechanically. The pulling force each time is small, which can greatly reduce the error and maintain the accuracy of the experimental results. When the connecting ball 63 and the protrusions 50 on both sides are not in contact, the spring four 57 and the spring three 52 are both in a compressed state, and according to Newton's second law, Figure 5 From the perspective of , the sum of the forces of the spring four 57 and the spring three 52 on the left side is equal to the sum of the forces of the spring four 57 and the spring three 52 on the right side. When the connecting ball 63 and the protrusion 50 are offset, the deformation of the spring four 57 on the same side will change, and then the force will change, which will eventually cause the arc plate two 24 and the wire harness to move laterally, causing the wire harness to bend, until the connecting ball 63 and the protrusion 50 are disconnected, and the forces on both sides are equal again. Finally, in the process of the arc plate two 24 moving upward, the wire harness is bent back and forth, providing a basis for the subsequent detection of the insulating sheath, without the need for manual bending; Furthermore, in the above working process, when the connecting ball 63 does not abut against the protrusion 50, the pressure sensor 58 has already sent out an electrical signal. After the connecting ball 63 and the protrusion 50 abut against each other, the electrical signal sent out by the pressure sensor 58 changes. The magnitude of the change of the pressure sensors 58 on both sides can be compared. If the magnitude of the change of the pressure sensor 58 is small, it means that the insulating sheath of the wiring harness is soft. If the magnitude of the change of the pressure sensor 58 is large, it means that the insulating sheath of the wiring harness is hard, thereby forming a simple detection effect of the hardness of the insulating sheath of the wiring harness; The round rod 27, telescopic rod 64, connecting block 59, and arc plate 24 can be approximately regarded as an isosceles trapezoid. Since the arc plate 24 will move back and forth relative to the round rod 27, the angle formed by the connecting block 59 and the arc plate 24 will change, thereby causing the rotating ring 18 to rotate relative to the fixed ring 16. However, since the clamping tube 61 and the insulating sheath are against each other, the clamping tube 61 will not rotate under the obstruction of the insulating sheath, thereby causing the spring 5 19 to deform, and the torque sensor sends a corresponding electrical signal. During this process, if there are no defects on the surface of the insulating sheath, the electrical signals sent by the torque sensors on both sides are the same in size. If there are certain defects on the surface of the insulating sheath, the friction force on the surface of the insulating sheath will be different in size, and the electrical signals sent by the torque sensors on both sides will be different in size, thereby forming a simple detection effect on the surface of the insulating sheath.
