An assembly platform for automobile wiring harness assembly detection and use method thereof

Abstract

The present invention discloses an assembly table for automobile wire harness assembly detection and its usage method, including a bench, a first installation table and a second installation table. A pallet is installed on one side of the top of the bench, and a steering gear is installed at one end of the bottom of the pallet. In the present invention, during processing, the metal sheet wrapping the wire head needs to be passed through the shaping groove. The inner vertical cross-section of the shaping groove is a "冂"-shaped through groove. The metal sheet will undergo corresponding deformation when passing through the shaping groove. Subsequently, the end of the deformed metal sheet is sent into the corresponding shaping groove. When the bare metal wire at the end of the cable enters the metal sheet in the shaping groove, the metal sheet end is tightly pressed and wrapped around the end of the metal wire by pressing down the pressing block in cooperation with the shaping groove, ensuring that the metal wire will not spread. At the same time, during this process, the downward-moving second cutter will cut off the end of the metal sheet after extrusion deformation, thereby completing the assembly and improving production efficiency.

[0012] Furthermore, the base frame, guide plate and steering gear form a rotating structure;

[0018] Furthermore, a slice is provided in the middle of each of the first clamping grooves.

[0019] Furthermore, each of the shaping grooves passes through both ends of the shaping plate, and each of the shaping grooves is distributed correspondingly to a pressing groove, and each of the pressing grooves is distributed correspondingly to a second lead tube.

[0020] The method for using the assembly bench for automobile wiring harness assembly detection comprises the following steps:

[0021] Step 1: Pass the ends of the cables to be processed from the top of the second gear rod and the bottom of the first gear rod in turn, and insert the ends of each cable into the circular through groove formed by the combination of the corresponding first cable groove and the second cable groove in turn, then turn on the external power supply, start the motor, drive the conveying roller to rotate, and continue to move the cable in a straight line direction through the rotating conveying roller until the end of the cable passes through the corresponding first lead tube;

[0022] Step 2: Continue to start the conveying roller and continue to convey the cables until all the cables pass through the second clamping groove corresponding to the top of the first clamping platform in sequence. When the end of the cable completely passes through the first clamping platform, close the conveying roller and start the third hydraulic cylinder at the same time to drive the fixed seat and the second clamping platform to press down at the same time, so that the first clamping groove and the second clamping groove are closed with each other, and the outer skin of the cable is clamped in coordination with the slice, and the outer skin of the contact part of the slice is cut;

[0023] Step 3: At this time, start the second hydraulic cylinder to push the first cutter to slide upward along the guide rod. Cooperate with the top edge of the first clamping table to cut off the redundant part at the end of the cable. After the first cutter retracts to the initial position, start the first hydraulic cylinder to push the first clamping table to start sliding towards the end away from the lead table. At this time, since the grooves at both ends of the top of the first clamping table fit and connect with the squares at both ends of the bottom of the second clamping table, the first clamping table drives the second clamping table to slide synchronously while sliding. At this time, cooperate with the upper and lower groups of slicing blades to break the damaged outer skin after cutting, and drive the broken outer skin to break away; then the first hydraulic cylinder retracts, driving the first clamping table to return to the initial position, and then restart the third hydraulic cylinder to drive the second clamping table to retract, and under the action of the second spring, return to the initial position;

[0024] Step 4: Then restart the conveying roller to push the cable to continue sliding forward. After pushing the cut outer skin out of the first clamping table, the conveying roller rotates in the reverse direction to drive the cable to retract. Then turn off the conveying roller and start the steering gear to drive the entire chassis and guide plate to rotate 90°, driving the top of the cable to align with the second lead pipe;

[0025] Step 5: Pass the wrapping metal sheet to be used through the end of the shaping groove and through the shaping plate. The vertical cross-section of the shaping groove is in the shape of "冂". After the metal sheet passes through the shaping groove, a continuous metal sheet with a vertical cross-section in the shape of "冂" will be formed. Then the end of the shaped metal sheet passes through the corresponding pressing groove;

[0026] Step 6: Restart the conveying roller 16 again to convey the bare metal wire at the end of the cable into the metal sheet inside the pressing groove 36. Then start the fourth hydraulic cylinder 38 to drive the pressing block 39 and the second cutter 40 to press down synchronously. During the downward pressing process of the pressing block 39 first, cooperate with the pressing groove 36 to squeeze the metal sheet so that it wraps around the bare metal wire of the cable. Then the downward pressing second cutter 40 cuts the metal sheet passing through the shaping plate 41;

[0027] Step 7: Restart the conveying roller to drive the cable to retract. Then restart the steering gear again to drive the entire chassis and guide plate to rotate 90° in reverse. Then restart the conveying roller again to convey the cable through the first clamping table. Finally, start the CCD camera detection module to visually detect the wrapping state of the metal sheet at the end of the cable. Then repeat Steps 2 to 6 to continuously perform cyclic detection and processing.

[0028] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0029] 1. In the present invention, a steering gear, a chassis and a guide plate are provided. A plurality of first cable grooves are provided at the bottom of the guide plate. Cooperating with the second cable grooves at the tops of two limit blocks, a cylindrical channel is formed to guide the conveying direction of the cable. At the bottom, a conveying roller made of rubber is provided. A plurality of arc-shaped grooves corresponding to the first cable grooves are provided on the conveying roller. The conveying roller always maintains an upward pressure under the action of four first springs, and the gap between the conveying roller and the first cable groove is adjustable within the stretching range of the first spring, which can adapt to cables of different diameters, can always maintain sufficient pressure on the cable, avoid excessive relative sliding during the conveying process, improve the conveying distance accuracy, and will not cause excessive extrusion to the cable, avoid imperceptible damage to the outer skin of the cable. At the same time, the steering gear can drive to adjust the conveying direction of the wire, improving the convenience of use.

[0030] 2. In the present invention, a cushion block, a pressing groove and a shaping plate are provided. During processing, the metal sheet wrapping the wire end needs to pass through the shaping groove. The inner vertical section of the shaping groove is a "冂"-shaped through groove. The metal sheet will deform correspondingly when passing through the shaping groove. Subsequently, the end of the deformed metal sheet is sent into the corresponding shaping groove. When the bare metal wire at the end of the cable enters the metal sheet in the shaping groove, the metal sheet end is tightly pressed and wrapped around the end of the metal wire by pressing the pressing block in cooperation with the shaping groove to ensure that the metal wire will not spread. At the same time, during this process, the downward-moving second cutting knife will cut off the end of the metal sheet after extrusion deformation, thus completing the assembly and improving the production efficiency.

[0031] 3. In the present invention, a first clamping table and a second clamping table are provided. After the cable end after assembly passes between the first clamping table and the second clamping table, it will pass directly below the CCD camera detection module. The visual inspection of the assembly quality is carried out through the CCD camera detection module. After the detection is completed, the cable can be continuously conveyed according to the required length of the cable to be produced. When the required length is reached, the cable passing through is clamped by the first clamping table and the second clamping table, and then cut with the first cutting knife. And when the first clamping table and the second clamping table are closed to each other, the first clamping groove and the second clamping groove are combined to limit the left-right sliding of the metal wire. At the same time, the outer skin of the cable can be cut with a relatively shallow depth by the upper and lower groups of slicing knives. Subsequently, the first hydraulic cylinder is used to push the first clamping table and the second clamping table to slide forward simultaneously, which can assist in peeling the outer skin of the cut cable, facilitating cyclic processing and further improving the processing efficiency.

[0066] Please refer to Fig.11 、 Fig.12 、 Fig.13 and Fig.14 As shown in

[0067] Specifically, the vertical cross-section of the shaping groove 42 is in the shape of "冂". When the metal sheet passes through the shaping groove 42, corresponding deformation will occur.

[0068] As a further illustration of this embodiment, the deformed metal sheet will form a tubular-like structure with an unconnected bottom.

[0069] The usage method of the assembly table for automobile wire harness assembly detection includes the following steps:

[0070] Step 1: The ends of the cables to be processed are sequentially passed through above the second baffle 4 and below the first baffle 3, and the end of each cable is sequentially inserted into the circular through groove formed by the corresponding first wire groove 7 and the second wire groove 9. Subsequently, the external power supply is turned on, the motor 15 is started, and the conveying roller 16 is driven to rotate. The cable is continuously moved in a straight line direction through the rotating conveying roller 16 until the end of the cable passes through the corresponding first lead tube 11;

[0071] Step 2: Continue to start the conveying roller 16 to continuously convey the cable until all the cables sequentially pass through the corresponding second clamping grooves 44 at the top of the first clamping table 21. When the end of the cable completely passes through the first clamping table 21, turn off the conveying roller 16, and at the same time start the third hydraulic cylinder 26 to drive the fixed seat 27 and the second clamping table 28 to press down simultaneously, so that the first clamping groove 43 and the second clamping groove 44 are closed with each other, cooperate with the slicing blade 45 to clamp the outer skin of the cable, and cut the outer skin in contact with the slicing blade 45;

[0072] Step 3: At this time, start the second hydraulic cylinder 22 to push the first cutting knife 23 to slide upward along the guide rod 24, and cooperate with the top edge of the first clamping table 21 to cut off the redundant part at the end of the cable. After the first cutting knife 23 retracts to the initial position, start the first hydraulic cylinder 20 to push the first clamping table 21 to start sliding towards the end away from the lead table 10. At this time, since the grooves at both ends of the top of the first clamping table 21 fit and connect with the blocks at both ends of the bottom of the second clamping table 28, the first clamping table 21 drives the second clamping table 28 to slide synchronously while sliding. At this time, cooperate with the upper and lower groups of slicing blades 45 to break the damaged outer skin after cutting, and drive the broken outer skin to break away; Subsequently, the first hydraulic cylinder 20 retracts, driving the first clamping table 21 to return to the initial position, and then restart the third hydraulic cylinder 26 to drive the second clamping table 28 to retract and return to the initial position under the action of the second spring 29;

[0073] Step 4: Subsequently, restart the conveying roller 16 to push the cable to continue sliding forward. After the cut outer skin is pushed out of the first clamping table 21, the conveying roller 16 rotates in the reverse direction to drive the cable to be recycled. Then turn off the conveying roller 16, start the steering gear 30 to drive the whole bottom frame 5 and the guide plate 6 to rotate 90°, and drive the top end of the cable to align with the second lead tube 35;

[0074] Step 5: Pass the wrapping metal sheet to be used through the end of the shaping groove 42 and through the shaping plate 41. The vertical cross-section of the shaping groove 42 is in the shape of "冂". The metal sheet will form a continuous metal sheet with a vertical cross-section in the shape of "冂" after passing through the shaping groove 42. Subsequently, the end of the shaped metal sheet passes through the corresponding pressing groove 36;

[0075] Step 6: Start the conveying roller 16 again to convey the exposed metal wire at the end of the cable to the metal sheet inside the shaping groove 42, then start the fourth hydraulic cylinder 38 to drive the pressing block 39 and the second cutter 40 to press down synchronously. The pressing block 39 first cooperates with the shaping groove 42 to squeeze the metal sheet during the pressing process, so that it wraps around the exposed metal wire of the cable, and then the second cutter 40 that is pressed down cuts the metal sheet that passes through the shaping plate 41;

[0076] Step 7: Restart the conveying roller 16 to drive the cable back, then start the servo 30 again to drive the base frame 5 and the guide plate 6 to rotate 90° as a whole, then start the conveying roller 16 again, and convey the cable through the first clamping table 21. Finally, start the CCD camera detection module 31 to perform a visual inspection on the metal sheet wrapping state at the end of the wire, and then repeat steps 2 to 6 to continue the cyclic detection process.

[0077] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.

5. The method for using the assembly platform for automobile wiring harness assembly detection according to claim 4 is characterized in that: The following steps are involved: Step 1: The ends of the cables to be processed are passed through the top of the second gear rod (4) and the bottom of the first gear rod (3) in sequence, and the ends of each cable are inserted into the corresponding circular through grooves formed by the combination of the first cable groove (7) and the second cable groove (9) in sequence, and then the external power supply is turned on, the motor (15) is started, and the conveying roller (16) is driven to rotate, and the rotating conveying roller (16) continues to move the cable in a straight line direction until the end of the cable passes through the corresponding first lead tube (11); Step 2: Continue to start the conveying roller (16) and continuously convey the cable until all the cables pass through the corresponding second clamping grooves (44) on the top of the first clamping table (21) in sequence. When the end of the cable completely passes through the first clamping table (21), turn off the conveying roller (16), and at the same time start the third hydraulic cylinder (26) to drive the fixed seat (27) and the second clamping table (28) to press down simultaneously, so that the first clamping groove (43) and the second clamping groove (44) are closed to each other, cooperate with the slicer (45) to clamp the outer skin of the cable, and cut the outer skin in contact with the slicer (45). Step 3: At this time, start the second hydraulic cylinder (22) to push the first cutter (23) to slide upward along the guide rod (24), and cooperate with the top edge of the first clamping table (21) to cut off the redundant part at the end of the cable. After the first cutter (23) retracts to the initial position, start the first hydraulic cylinder (20) to push the first clamping table (21) to start sliding towards the end away from the lead table (10). At this time, since the grooves at both ends of the top of the first clamping table (21) fit and connect with the squares at both ends of the bottom of the second clamping table (28), the first clamping table (21) drives the second clamping table (28) to slide synchronously while sliding. At this time, cooperate with the upper and lower groups of slicers (45) to break the damaged outer skin after cutting and drive the broken outer skin to break away; then the first hydraulic cylinder (20) retracts, drives the first clamping table (21) to return to the initial position, and then restart the third hydraulic cylinder (26) to drive the second clamping table (28) to retract and return to the initial position under the action of the second spring (29). Step 4: Then restart the conveying roller (16) to push the cable to continue sliding forward. After pushing the cut outer skin out of the first clamping table (21), the conveying roller (16) rotates in the reverse direction to drive the cable to be recycled. Then turn off the conveying roller (16) and start the servo motor (30) to drive the entire chassis (5) and the guide plate (6) to rotate 90°, driving the top end of the cable to align with the second lead pipe (35). Step 5: Pass the wrapping metal sheet to be used through the end of the shaping groove (42) and through the shaping plate (41). The vertical cross-section of the shaping groove (42) is in the shape of "冂". After the metal sheet penetrates the shaping groove (42), a continuous metal sheet with a vertical cross-section in the shape of "冂" will be formed. Then the end of the shaped metal sheet passes through the corresponding pressing groove (36). Step 6: Start the conveying roller (16) again to convey the bare metal wire at the end of the cable into the metal sheet inside the pressing groove (36). Then start the fourth hydraulic cylinder (38) to drive the pressing block (39) and the second cutter (40) to press down synchronously. During the downward pressing process of the pressing block (39) first, it cooperates with the pressing groove (36) to squeeze the metal sheet so that it wraps around the bare metal wire of the cable. Then the downward pressing second cutter (40) cuts the metal sheet passing through the shaping plate (41). Step 7: Restart the conveying roller (16) to drive the cable back, then start the steering gear (30) again to drive the base frame (5) and the guide plate (6) to rotate 90 degrees as a whole, then start the conveying roller (16) again to convey the cable through the first clamping platform (21), and finally start the CCD camera detection module (31) to perform a visual inspection on the metal sheet wrapping state at the end of the cable, and then repeat steps 2 to 6 to continue the cyclic detection process.
