Description

Technical Field

[0001] The invention relates to the technical field of automobile wire harness production, and in particular to an automobile wire harness assembly and detection device. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. The wiring harness refers to the contact terminal made of copper material, which is crimped with wires and cables, and then plastic-pressed with an insulator or an additional metal shell to form a component connecting the circuit.

[0003] Automotive wiring harnesses mainly include engine wiring harnesses, headlight wiring harnesses and air conditioning wiring harnesses. After the production of automotive wiring harnesses is completed, the electrical performance of the wiring harnesses needs to be tested to ensure that the wiring harnesses can be used normally.

[0004] When conducting electrical performance testing on existing automotive wiring harnesses, workers usually manually connect the interfaces at both ends of the detector to the terminals at both ends of the wiring harness, and then the detector displays whether the data is normal. Since workers need to manually connect the detector to both ends of the wiring harness, the testing efficiency is slow. Summary of the invention

[0005] The purpose of the present invention is to provide an automobile wiring harness assembly detection device, which has the effect of improving the wiring harness detection efficiency.

[0006] The above technical purpose of the present invention is achieved through the following technical scheme: it includes a machine body, a wire harness feeding mechanism, a wire harness conveying mechanism and a wire harness detection mechanism, the wire harness conveying mechanism includes a first conveying roller and a second conveying roller which are arranged on the machine body in a horizontal direction, a conveyor belt is arranged between the first conveying roller and the second conveying roller, and a plurality of conveying blocks which match a wire harness are evenly arranged on the conveyor belt, the wire harness detection mechanism includes a detection plate, a first detector arranged at one end of the detection plate and a second detector arranged at the other end of the detection plate, the first detector and the second detector are electrically connected, the detection plate can be located directly above the adjacent conveying block, the machine body is provided with a first driving member for driving the detection plate to rise and fall, and the machine body is provided with a second driving member for driving the first conveying roller to rotate in a gap.

[0007] By adopting the above technical solution, when the wire harness needs to be inspected, the wire harness is sequentially conveyed to the conveying block through the wire harness feeding mechanism, and then the first conveying roller gap is driven to rotate through the second driving member, thereby driving the conveyor belt and the conveying block gap to convey the wire harness forward. When the conveying block conveys the wire harness to just below the inspection plate, the first driving member drives the inspection plate, the first detector and the second detector to descend until the first detector and the second detector respectively contact the two ends of the conveying block. At this time, the first detector and the second detector are respectively electrically connected to the two ends of the wire harness located in the conveying block, thereby detecting the electrical properties of the wire harness. After the inspection is completed, the first driving member drives the first detector and the second detector to rise, and then the second driving member drives the first conveying roller to rotate, so that the conveyor belt and the conveying block continue to The wiring harness is continuously conveyed to the bottom of the detection plate, so as to carry out electrical performance testing on the wiring harness in turn (it should be noted that the distance and interval time that the second driving member drives the conveying block to convey forward are coordinated with the time when the first driving member drives the detection plate to rise and fall for testing, so that the conveying block conveys the wiring harness forward in turn for testing); therefore, by setting the first detector and the second detector, after the first driving member drives the first detector and the second detector to descend synchronously, the electrical connection of the terminals at both ends of the wiring harness is automatically realized, so as to carry out electrical performance testing. At the same time, since the conveying block cooperates with the first driving member to convey the wiring harness forward in the gap, the wiring harness is passed through the bottom of the detection plate in turn for testing, and there is no need for workers to manually take out the wiring harnesses in turn and connect them to the detector for testing, thereby achieving the purpose of improving the efficiency of wiring harness testing.

[0008] The present invention is further configured as follows: the first driving member includes a bracket arranged on the body and a driving cylinder vertically arranged on the bracket, the output end of the driving cylinder is fixedly connected to the detection plate, and when the detection plate descends, the detection plate is located directly above the adjacent conveying block.

[0009] By adopting the above technical solution, a driving cylinder is set to drive the detection plate, the first detector and the second detector to rise and fall, thereby realizing automatic connection detection of the wiring harness below the detection plate, with a simple structure and convenient operation.

[0010] The present invention is further configured as follows: the second driving member includes a ring-shaped driving gear rotatably arranged at the end of the first conveying roller and a driving rack vertically arranged at one side of the detection plate, one side of the driving rack is meshed with the driving gear, when the detection plate rises, the driving rack can drive the driving gear and the first conveying roller to rotate synchronously, when the detection plate descends, the driving rack can drive the driving gear to rotate around the first conveying roller.

[0011] The present invention is further configured as follows: beveled tooth grooves are evenly provided on the inner wall of the driving gear, the beveled tooth grooves include a first beveled surface and a second beveled surface, a plurality of rotating members are provided at the end of the first conveying roller, the rotating members include a rotating block rotatably provided at the end of the first conveying roller, a fixed block provided at the end of the first conveying roller, and a rotating spring provided between the rotating block and the fixed block, when the end of the rotating block abuts against the first beveled surface, the driving gear can drive the first conveying roller to rotate synchronously, and when the end of the rotating block abuts against the second beveled surface, the driving gear can drive the rotating block to rotate in a direction close to the fixed block.

[0012] By adopting the above technical scheme, when the driving cylinder drives the detection plate to descend, the driving rack drives the driving gear to rotate. During the rotation of the driving gear, the second inclined surface on the helical tooth groove abuts against the end of the rotating block, pushing the end of the rotating block to rotate in the direction close to the fixed block, so that the driving gear rotates around the first conveying roller. Therefore, when the detection plate descends, the first conveying roller, the conveying block, etc. remain stationary, thereby facilitating the detection of the wiring harness after the first detector and the second detector descend. When the driving cylinder drives the detection plate to rise, the driving rack drives the driving gear to rotate. During the rotation of the driving gear, the first inclined surface on the helical tooth groove abuts against the end of the rotating block. At this time, the rotating block cannot rotate relative to the end of the first conveying roller. Therefore, the driving gear drives the rotating block and the first conveying roller to rotate synchronously through the first inclined surface, thereby driving The conveyor belt and the second conveyor roller rotate, and when the detection plate stops rising, the conveyor belt and the conveyor block just convey the wire harness to be detected forward to just below the detection plate; therefore, by setting a driving rack, a driving gear and a helical tooth groove, etc., the driving gear is driven to rotate in the process of the driving cylinder driving the detection plate to rise and fall, and then the helical tooth groove on the driving gear and the rotating block on the first conveyor roller are used to realize the stopping of the movement of the first conveyor roller and the conveyor block in the process of the detection plate descending, so as to facilitate the first detector and the second detector to detect the wire harness. At the same time, in the process of the detection plate rising, the first conveyor roller and the conveyor block are driven to convey the wire harness forward, so as to facilitate the detection of other wire harnesses in sequence. Without the need for additional power devices, the lifting and lowering of the detection plate and the movement of the wire harness are coordinated with each other, so that the electrical performance of the wire harness can be automatically detected in sequence.

[0013] The present invention is further configured as follows: the wire harness feeding mechanism comprises a storage hopper arranged on the machine body and a discharge port horizontally opened at the bottom end of the storage hopper and cooperating with the wire harness; a suction pipe is arranged on the machine body in a direction parallel to the conveying block; a feeding roller is rotatably arranged on the outer wall of the suction pipe; a suction pump connected to the end of the suction pipe is arranged on the machine body; the outer wall of the feeding roller can be movably fitted to the discharge port; a plurality of feeding rollers cooperating with the wire harness are evenly opened on the outer wall of the feeding roller The feeding trough can be located directly below the unloading port, the feeding trough can be located directly above the conveying block, the outer wall of the suction pipe is provided with a plurality of arc-shaped first air suction holes in the vertical direction, and a plurality of second air suction holes which can be connected with the first air suction holes are arranged in the feeding trough. When the feeding trough is located at the bottom end of the feeding roller, there is a set distance between the second air suction hole and the adjacent first air suction hole, and the machine body is provided with a third driving member for driving the feeding roller to rotate in the gap.

[0014] By adopting the above technical solution, when the wire harness is detected, the third driving member is turned on to drive the feeding roller to rotate in a gap, and by controlling the angle of each rotation of the feeding roller and the number of feeding troughs, each rotation of the feeding roller causes one feeding trough to rotate to the bottom of the unloading port, so that a wire harness falls from the unloading port into the feeding trough (the size of the feeding trough matches the wire harness, so it can only accommodate one wire harness). At the same time, one feeding trough rotates to the bottom of the conveying block, at which time the second air suction hole in the feeding trough is disconnected from the first air suction hole, so that the wire harness in the feeding trough falls into the conveying block directly below under the action of gravity (it should be noted that during the rotation of the feeding roller, the second air suction hole in the feeding trough with the wire harness is always connected to the first air suction hole. When the feeding roller rotates, the second air suction hole in the feeding trough with the wire harness is always connected to the first air suction hole. When the material trough rotates to the bottom end of the loading roller, the second air suction hole in the loading trough is separated from the first air suction hole, so that the wire harness can fall into the conveying block below); therefore, by setting the loading roller, the loading trough and the suction pipe, during the rotation of the loading roller gap, the wiring harness is automatically transferred from the storage hopper to the loading trough in sequence through the cooperation between the loading trough and the unloading port, and then through the cooperation between the first air suction hole and the second air suction hole, the wiring harness will not fall from the loading trough during the rotation of the loading roller, and then when the loading trough rotates to the bottom end of the loading roller, the first air suction hole is isolated from the second air suction hole, so that the wiring harness is transferred from the loading trough to the conveying block below, thereby realizing the automatic loading process of the entire wiring harness, and there is no need for workers to manually place the wiring harnesses one by one in the conveying block, thereby further improving the efficiency of wiring harness detection.

[0015] The present invention is further configured as follows: the third driving member includes a first synchronous wheel arranged at the end of the feeding roller and a second synchronous wheel arranged at the end of the second conveying roller, and a first synchronous belt is arranged between the first synchronous wheel and the second synchronous wheel.

[0016] By adopting the above technical solution, a first synchronous wheel and a second synchronous wheel are set, and the first conveyor roller is driven to rotate during the rising process of the detection plate, and then the second conveyor roller is driven to rotate through the conveyor belt. The second conveyor roller drives the loading roller to rotate through the first synchronous wheel, the second synchronous wheel and the first synchronous belt (it should be noted that the angle of each rotation of the loading roller driven by the second conveyor roller is matched with the number of loading slots on the loading roller, and the interval between the conveying blocks is matched with the distance the conveying blocks move forward each time). In this way, the driving cylinder drives the first conveyor roller, the loading roller and other gaps to rotate during the lifting and lowering of the detection plate. There is no need to add an additional power device. At the same time, the loading and conveying of the wire harness and the detection of the wire harness are coordinated, thereby realizing automatic loading, conveying and detection of the wire harness, greatly improving the efficiency of wire harness detection.

[0017] The present invention is further configured as follows: a second synchronous belt is provided between the first conveying roller and the second conveying roller.

[0018] By adopting the above technical solution, a second synchronous belt is provided to increase the connection between the first conveying roller and the second conveying roller, thereby ensuring that the first conveying roller and the second conveying roller rotate synchronously.

[0019] The present invention is further configured as follows: a plurality of limit springs are vertically arranged at the lower end of the detection plate, a limit plate is movably arranged on the body in a direction parallel to the detection plate, the bottom end of the limit spring is fixedly connected to the limit plate, the limit plate is located between the first detector and the second detector, the limit plate can be located directly above the adjacent conveying block, and the horizontal plane where the limit plate is located is lower than the horizontal plane where the bottom end of the first detector is located.

[0020] By adopting the above technical solution, when the detection plate drives the first detector and the second detector to descend, the detection plate also drives the limit spring and the limit plate to descend. The limit plate first contacts the conveying block below, and then the detection plate continues to descend, compressing the limit spring, so that the limit spring applies elastic force to the limit plate to press the wiring harness on the conveying block. Then the first detector and the second detector contact the two ends of the conveying block to perform electrical performance detection on the wiring harness in the conveying block. Therefore, by setting the limit spring and the limit plate, the wiring harness in the conveying block can be compressed and fixed, thereby ensuring the stability of the subsequent first detector and the second detector during electrical performance detection.

[0021] The present invention is further configured as follows: a plurality of limit rods corresponding to the limit springs are vertically arranged on the top of the limit plate, and the limit rods movably pass through the limit springs and the detection plate.

[0022] By adopting the above technical solution, a limit rod is provided to guide the limit spring, thereby improving the stability of the limit spring during movement.

[0023] The present invention is further configured as follows: the bracket includes support rods symmetrically arranged on both sides of the body along the vertical direction and a support plate arranged between the two support rods, and the two support rods are movably passed through the two ends of the detection plate respectively.

[0024] By adopting the above technical solution and arranging support rods, the stability of the detection plate during the lifting process is improved.

[0025] The beneficial effects of the present invention are:

[0026] 1. By setting the first detector and the second detector, the first driving member drives the first detector and the second detector to descend synchronously, and the terminals at both ends of the wiring harness are automatically electrically connected, so as to perform electrical performance testing. At the same time, since the conveying block cooperates with the first driving member to convey the wiring harness forward, the wiring harness passes through the bottom of the detection plate in turn for testing, and workers do not need to manually take out the wiring harnesses in turn and connect them to the detectors for testing, thereby achieving the purpose of improving the efficiency of wiring harness testing.

[0027] 2. By setting a driving rack, a driving gear and a helical tooth groove, etc., the driving cylinder drives the driving gear to rotate in the process of driving the detection plate to rise and fall, and then the helical tooth groove on the driving gear and the rotating block on the first conveying roller are used to stop the movement of the first conveying roller and the conveying block in the process of the detection plate descending, so as to facilitate the first detector and the second detector to detect the wire harness. At the same time, during the rising process of the detection plate, the first conveying roller and the conveying block are driven to convey the wire harness forward, so as to facilitate the detection of other wire harnesses in sequence. Without the need for additional power devices, the lifting and lowering of the detection plate and the movement of the wire harness are coordinated with each other, so that the electrical performance of the wire harness can be automatically detected in sequence.

[0028] 3. By setting the first synchronous wheel and the second synchronous wheel, the first conveyor roller is driven to rotate during the rising process of the detection plate, and then the second conveyor roller is driven to rotate through the conveyor belt. The second conveyor roller drives the loading roller to rotate through the first synchronous wheel, the second synchronous wheel and the first synchronous belt (it should be noted that the angle of each rotation of the loading roller driven by the second conveyor roller is matched with the number of loading slots on the loading roller, and the interval between the conveying blocks is matched with the distance each time the conveying block moves forward). In this way, the driving cylinder drives the first conveyor roller, the loading roller and other gaps to rotate during the lifting and lowering of the detection plate. There is no need to add an additional power device. At the same time, the coordination between the loading and conveying of the wire harness and the detection of the wire harness is realized, thereby realizing the automatic loading, conveying and detection process of the wire harness, greatly improving the efficiency of wire harness detection.

When the detection plate 4a descends, the detection plate 4a is located directly above the adjacent conveying block 6.

[0039] Further, the second driving member 8 includes a ring-shaped driving gear 8a rotatably arranged at the end of the first conveying roller 3a and a driving rack 8b vertically arranged at one side of the detection plate 4a, one side of the driving rack 8b is meshed with the driving gear 8a, when the detection plate 4a rises, the driving rack 8b can drive the driving gear 8a and the first conveying roller 3a to rotate synchronously, when the detection plate 4a descends, the driving rack 8b can drive the driving gear 8a to rotate around the first conveying roller 3a.

[0040] Furthermore, the inner wall of the driving gear 8a is evenly provided with oblique tooth grooves 9, and the oblique tooth grooves 9 include a first inclined surface 9a and a second inclined surface 9b.

When the end of the rotating block 10a contacts the second inclined surface 9b, the driving gear 8a can drive the rotating block 10a to rotate in a direction close to the fixed block 10b.

[0041] Furthermore, the wire harness feeding mechanism 2 includes a storage hopper 2a arranged on the machine body 1 and a discharge port 2b which is horizontally opened at the bottom end of the storage hopper 2a and matches the wire harness. A suction pipe 11 is arranged on the machine body 1 in a direction parallel to the conveying block 6. A feeding roller 12 is rotatably arranged on the outer wall of the suction pipe 11. A suction pump 13 which is connected to the end of the suction pipe 11 is arranged on the machine body 1. The outer wall of the feeding roller 12 can be movably fitted to the discharge port 2b. A plurality of feeding grooves 14 which match the wire harness are evenly opened on the outer wall of the feeding roller 12. The loading chute 14 can be located directly below the unloading port 2b, and the loading chute 14 can be located directly above the conveying block 6. The outer wall of the suction pipe 11 is provided with a plurality of arc-shaped first air suction holes 15 in the vertical direction. The loading chute 14 is provided with a plurality of second air suction holes 16 that can be connected with the first air suction holes 15. When the loading chute 14 is located at the bottom end of the loading roller 12, there is a set distance between the second air suction hole 16 and the adjacent first air suction hole 15. The machine body 1 is provided with a third driving member 17 for driving the loading roller 12 to rotate in a gap.

[0042] Furthermore, the third driving member 17 includes a first synchronous wheel 17a disposed at the end of the feeding roller 12 and a second synchronous wheel 17b disposed at the end of the second conveying roller 3b, and a first synchronous belt 18 is disposed between the first synchronous wheel 17a and the second synchronous wheel 17b.

[0043] Furthermore, a second synchronous belt 19 is provided between the first conveying roller 3 a and the second conveying roller 3 b.

[0044] Furthermore, a plurality of limit springs 20 are vertically arranged at the lower end of the detection plate 4a, and a limit plate 21 is movably arranged on the body 1 in a direction parallel to the detection plate 4a. The bottom end of the limit spring 20 is fixedly connected to the limit plate 21, and the limit plate 21 is located between the first detector 4b and the second detector 4c. The limit plate 21 can be located directly above the adjacent conveying block 6, and the horizontal plane where the limit plate 21 is located is lower than the horizontal plane where the bottom end of the first detector 4b is located.

[0045] Furthermore, a plurality of limit rods 22 corresponding to the limit springs 20 are vertically arranged at the top of the limit plate 21 , and the limit rods 22 are movable through the limit springs 20 and the detection plate 4 a .

[0046] Furthermore, the bracket 7a includes support rods 23 symmetrically arranged on both sides of the body 1 along the vertical direction and a support plate 24 arranged between the two support rods 23, and the two support rods 23 are movable through the two ends of the detection plate 4a respectively.

[0047] When the wire harness needs to be inspected, firstly, the driving cylinder 7b is turned on, and the lifting speed of the driving cylinder 7b is adjusted. When the driving cylinder 7b drives the inspection plate 4a to descend, the driving rack 8b is used to drive the driving gear 8a to rotate. During the rotation of the driving gear 8a, the second inclined surface 9b on the helical tooth groove 9 abuts against the end of the rotating block 10a, and the end of the rotating block 10a can be pushed to rotate in a direction close to the fixed block 10b, so that the driving gear 8a rotates around the first conveying roller 3a. Therefore, when the inspection plate 4a descends, the first conveying roller 3a, the conveying block 6, etc. remain stationary, so that it is convenient for the first detector 4b and the second detector 4c to detect the wire harness after they descend. The detection plate 4a drives the first detector 4b and the second detector 4c to descend until the first detector 4b and the second detector 4c respectively contact the two ends of the conveying block 6. At this time, the first detector 4b and the second detector 4c are respectively electrically connected to the two ends of the wire harness located in the conveying block 6, so as to detect the electrical performance of the wire harness. After the detection is completed, the driving cylinder 7b drives the detection plate 4a, the first detector 4b and the second detector 4c to rise. When the detection plate 4a rises, the driving rack 8b drives the driving gear 8a to rotate. During the rotation of the driving gear 8a, the first inclined surface 9a on the helical tooth groove 9 contacts the end of the rotating block 10a. At this time, the rotating block 10 a cannot rotate relative to the end of the first conveyor roller 3a, so the driving gear 8a drives the rotating block 10a and the first conveyor roller 3a to rotate synchronously through the first inclined surface 9a, and then drives the conveyor belt 5 and the second conveyor roller 3b to rotate. The conveyor belt 5 conveys the detected wire harness forward, and at the same time conveys the next wire harness to be detected and the conveying block 6 to the bottom of the detection plate 4a. During the rotation of the second conveyor roller 3b, the first synchronous belt 18, the first synchronous wheel 17a, etc. drive the feeding roller 12 to rotate. During the rotation of the feeding roller 12, the outer wall of the feeding roller 12 contacts the unloading port 2b until the feeding roller 12 stops rotating. At this time, the top of the feeding roller 12 The loading trough 14 is located just below the unloading port 2b. A wire harness enters the loading trough 14 through the unloading port 2b under the action of gravity and the suction provided by the first suction hole 15 and the second suction hole 16. At the same time, the loading trough 14 located at the bottom of the loading roller 12 is just located just above the conveying block 6. The wire harness is transferred from the loading trough 14 to the conveying block 6 under the action of gravity (at this time, the first suction hole 15 and the second suction hole 16 are in a disconnected state). When the detection plate 4a stops rising, the conveyor belt 5 and the conveying block 6 just convey the wire harness to be detected to the bottom of the detection plate 4a (it should be noted that the conveying block 6 is provided with a groove that matches the wire harness, such as Figure 1As shown, the conveying block 6 can drive the wire harness to be conveyed forward); by driving the cylinder 7b to drive the detection plate 4a to rise and fall, the detection process of the wire harness below the detection plate 4a is completed, and at the same time, the first conveying roller 3a and the second conveying roller 3b are driven to convey the wire harness and the conveying block 6 forward, and the feeding roller 12 can also be driven to rotate to complete the automatic feeding process of the wire harness. The whole process is interconnected and coordinated and carried out automatically. There is no need for workers to manually take out the wire harnesses one by one and connect them to the detector for detection, thereby achieving the purpose of improving the efficiency of wire harness detection.

[0048] By setting a driving cylinder 7b, the detection plate 4a, the first detector 4b and the second detector 4c are driven to rise and fall, thereby realizing automatic connection detection of the wiring harness below the detection plate 4a, with a simple structure and convenient operation.

[0049] By providing a driving rack 8b, a driving gear 8a and a helical tooth groove 9, the driving cylinder 7b drives the driving gear 8a to rotate in the process of driving the detection plate 4a to rise and fall, and then the helical tooth groove 9 on the driving gear 8a and the rotating block 10a on the first conveying roller 3a are used to realize the stopping of the first conveying roller 3a and the conveying block 6 in the process of the detection plate 4a descending, so as to facilitate the first detector 4b and the second detector 4c to detect the wire harness. At the same time, in the process of the detection plate 4a rising, the first conveying roller 3a and the conveying block 6 are driven to convey the wire harness forward, so as to facilitate the detection of other wire harnesses in sequence. Without the need for additional power devices, the lifting and lowering of the detection plate 4a and the movement of the wire harness are coordinated with each other, so that the electrical performance of the wire harness is automatically detected in sequence.

[0050] By providing a loading roller 12, a loading trough 14 and a suction pipe 11, during the gap rotation of the loading roller 12, the loading trough 14 and the discharge port 2b cooperate to realize that the wire harness is automatically transferred from the storage hopper 2a to the loading trough 14 in sequence, and then the first air suction hole 15 and the second air suction hole 16 cooperate to prevent the wire harness from falling from the loading trough 14 during the rotation of the loading roller 12. Then, when the loading trough 14 rotates to the bottom end of the loading roller 12, the first air suction hole 15 and the second air suction hole 16 are isolated, so that the wire harness is transferred from the loading trough 14 to the conveying block 6 below, thereby realizing the automatic loading process of the entire wire harness, and there is no need for workers to manually place the wire harnesses one by one in the conveying block 6, thereby further improving the efficiency of wire harness detection.

[0051] By setting the first synchronous wheel 17a and the second synchronous wheel 17b, the first conveying roller 3a is driven to rotate during the rising process of the detection plate 4a, and the second conveying roller 3b is driven to rotate through the conveyor belt 5. The second conveying roller 3b drives the loading roller 12 to rotate through the first synchronous wheel 17a, the second synchronous wheel 17b and the first synchronous belt 18 (it should be noted that the angle of each rotation of the loading roller 12 driven by the second conveying roller 3b is matched with the number of loading grooves 14 on the loading roller 12, and the interval between the conveying blocks 6 is matched with the distance that the conveying blocks 6 move forward each time). In this way, the driving cylinder 7b drives the first conveying roller 3a, the loading roller 12 and other gaps to rotate during the lifting and lowering of the detection plate 4a, without the need for additional power devices, and at the same time, the coordination between the loading and conveying of the wire harness and the detection of the wire harness is realized, thereby realizing the automatic loading, conveying and detection process of the wire harness, greatly improving the efficiency of the wire harness detection.

[0052] By providing the second synchronous belt 19, the connection between the first conveying roller 3a and the second conveying roller 3b is increased, so as to ensure that the first conveying roller 3a and the second conveying roller 3b rotate synchronously.

[0053] By providing the limit spring 20 and the limit plate 21, the wire harness in the conveying block 6 is pressed and fixed, thereby ensuring the stability of the subsequent electrical performance detection by the first detector 4b and the second detector 4c.

[0054] By providing the limiting rod 22 , the limiting spring 20 is guided to improve the stability of the limiting spring 20 during movement.

[0055] The support rod 23 is provided to improve the stability of the detection plate 4a during the lifting process. It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the various embodiments can be referred to each other.

[0056] The above description is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. Any changes or modifications made by a person skilled in the art in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
