Description

Technical Field

[0001] The present invention relates to the technical field of wire harness processing equipment, and in particular to a fully automatic wire harness threading, bolting and crimping plastic shell assembly equipment. Background Art

[0002] A wiring harness is a component made of copper-stamped contact terminals crimped onto wires and cables, then covered with plastic-molded insulation or a metal casing, to form a bundled circuit. The wiring harness industry chain encompasses wires and cables, connectors, wiring harness processing equipment, wiring harness manufacturing, and downstream application industries. Wire harnesses are currently widely used in automobiles, home appliances, computers and communications equipment, and various electronic instruments and meters.

[0003] In the fields of home appliance and automobile manufacturing, various wire harnesses are needed, and the processing of wire harnesses includes various operations such as cutting, full stripping, partial stripping, waterproof plugging, coding, and terminal crimping. Although there are specialized processing equipment to complete the feeding cutting, coil bundling, and stripping, these equipment cannot be effectively connected and need to be implemented manually. Therefore, wire harness processing and assembly cannot be fully automated, requiring a large amount of manpower, equipment, and site resources. At the same time, a lot of time is wasted due to product turnover. In the processing process, testing is also required to ensure that the wire harness obtained after several steps meets the application standards. Blindly carrying out the processing without testing not only has low work efficiency, but also high labor intensity, and the quality of the resulting wire harness products is uneven.

DETAILED DESCRIPTION

[0055] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0056] A fully automatic wire harness threading, bolt crimping and plastic shell assembly device includes a control terminal and a detection component connected to the control terminal signal. The detection component transmits the detection results to the control terminal and stores the detection results. The aforementioned detection component includes a wire harness sequence detection module 4, a core wire number detection module 7 and a terminal crimping condition detection module 9;

[0057] Figure 1 The schematic diagram shows the control system of the fully automatic wire harness threading and crimping plastic shell assembly equipment. Figure 1 The content shown here describes the control principle of the fully automatic wire harness threading and crimping plastic shell assembly equipment. The various steps involved are implemented based on several working modules distributed on the workbench. The distribution and overall structure are shown in the figure. Figure 2 shown.

[0058] The aforementioned wire harness sequence detection module 4 is used to detect the wire harness sequence after the outer sheath of the wire harness is stripped by the wire stripping mechanism and adjust the wire sequence;

[0059] The aforementioned core wire quantity detection module 7 is used to detect the number of core wires after the insulation layer in the wire harness is stripped by the stripping mechanism. The aforementioned control terminal controls the operation of the terminal crimping mechanism 8, the molded shell plugging mechanism 10 and the NG cutting mechanism 11 according to the detection result;

[0060] The aforementioned terminal crimping condition detection module 9 is used to detect the terminal crimping condition after being processed by the terminal crimping mechanism 8, and the control terminal adjusts the operation of the molded case plug-in mechanism 10 and the NG cutting mechanism 11 according to the detection result;

[0061] The aforementioned wire stripping mechanism, wire harness sequence detection module 4, stripping mechanism, core wire quantity detection module 7, terminal crimping mechanism 8, terminal crimping condition detection module 9, plastic shell plug-in mechanism 10 and NG cutting mechanism 11 are arranged in sequence on the workbench 1; a clamping claw assembly 12 for grabbing and fixing the wire harness is provided based on the length direction of the workbench 1.

[0062] Figure 3 The overall structure of the wiring harness sequence detection module 4 in the fully automatic wiring harness threading and crimping plastic shell assembly equipment is shown schematically. Figure 3 The content shown in the figure is specifically described for the wiring harness sequence detection module 4. The wiring harness sequence detection module 4 includes a branching clamp 41 arranged facing the clamp assembly 12, which is used to clamp the inner core wire exposed after the outer sheath of the wiring harness is stripped by the wire stripping mechanism. A first CCD lens 44 is vertically fixed above the branching clamp 41. The branching clamp 41 is fixed on the first rotating disk 42. The rotation adjustment of the branching clamp 41 is completed by rotating the rotating wheel. The line sequence image of the inner core wire obtained is transmitted to the control terminal through the first CCD lens 44. The control terminal determines the color sequence and color ratio of the inner core wire to determine whether it is necessary to adjust the line sequence of the inner core wire clamped by the branching clamp 41 by rotating the first rotating disk 42.

[0063] In some embodiments, the first rotating disk 42 can be directly coaxially fixed with the rotating shaft of the servo motor, and the rotation of the servo motor drives the first rotating disk 42 to rotate, thereby completing the adjustment of the line sequence of the inner core wire. During the adjustment process, the first CCD lens 44 obtains the line sequence image of the inner core wire in real time and transmits it to the control terminal for judgment, and the control terminal determines whether it is necessary to continue to run the servo motor.

[0064] In other embodiments, the wire splitting clamp 41 needs to perform a certain degree of reciprocating motion in a direction perpendicular to the clamp assembly 12, so the aforementioned first rotating disk 42 is rotatably fixed to the end of the telescopic rod of the cylinder, and the telescopic rod and the first rotating disk 42 are connected by a bearing. At this time, if the first rotating disk 42 needs to be rotated, a servo motor is also required. In addition, the second rotating disk 43 is coaxially fixed to the rotating shaft of the servo motor, and the first rotating disk 42 and the second rotating disk 43 are connected by a belt or a gear set, so that the servo motor drives the second rotating disk 43 as the active rotating disk, thereby driving the second rotating disk 43 to rotate, thereby completing the rotation adjustment of the wire splitting clamp 41. It is worth noting that the aforementioned cylinder can be replaced with an electric cylinder.

[0065] The wire stripping mechanism is described in detail below. The wire stripping mechanism includes a ring cutting mechanism 31 and a wire twisting mechanism 32 which are sequentially arranged on the workbench 1 . Figure 4 The schematic diagram shows the overall structure of the ring cutting mechanism 31 in the fully automatic wire harness threading and crimping plastic shell assembly equipment, combined with Figure 4 As shown, the circular cutting mechanism 31 includes a circular cutting knife, which can reciprocate along the width direction of the workbench 1. That is, when the wire harness moves to the work station under the action of the clamping jaw assembly 12, the circular cutting knife moves forward and tightens the blade, and then retreats to its original position, completing the stripping of the outer sheath of the wire harness, and then the blade can be released.

[0066] Figure 5 The schematic diagram shows the overall structure of the wire twisting mechanism 32 in the fully automatic wire harness threading and crimping plastic shell assembly equipment, combined with Figure 5As shown, the thread twisting mechanism 32 includes a clamping cylinder disposed facing the clamping jaw assembly 12. A first movable plate 321 and a second movable plate 322 are movably disposed based on the position of the inner side of the clamping jaw. The movement directions of the first movable plate 321 and the second movable plate 322 are perpendicular to the movement direction of the clamping jaw cylinder and opposite to the movement direction of the first movable plate 321 and the second movable plate 322. A slide groove is provided perpendicular to the length of the clamping jaw and on the inner side of the clamping jaw. Slide rails are fixedly disposed on the first movable plate 321 and the second movable plate 322. The slide rails and the slide grooves cooperate to movably fix the first movable plate 321 and the second movable plate 322 relative to the clamping jaw. Polyurethane pads 323 are fixedly disposed on opposite sides of the first movable plate 321 and the second movable plate 322. The inner core wire is placed between the polyurethane pads 323. The reciprocating motion of the first movable plate 321 and the second movable plate 322 in opposite directions spreads the reverse twist of the inner core wire. The aforementioned polyurethane cushion 323 can be replaced by a cushion made of any other material, as long as it can meet the softness, hardness and friction requirements of the polyurethane cushion 323.

[0067] Regarding the movement of the first movable plate 321 and the second movable plate 322, the first movable plate 321 and the second movable plate 322 are driven to reciprocate in opposite directions by a first connecting rod 324 and a second connecting rod 325, respectively, driven by a motor. In another embodiment, a driving gear is coaxially fixed to the rotating shaft of the motor, and a first gear and a second gear are provided to mesh with the driving gear. The first gear and the second gear are fixed above and below the driving gear, respectively. When the driving gear rotates, the first gear and the second gear rotate in opposite directions under the drive of the driving gear. In this case, a first rack and a second rack are fixed to the sides of the first movable plate 321 and the second movable plate 322, respectively. The first rack meshes with the first gear, and the second rack meshes with the second gear. The first gear and the second gear drive the first movable plate 321 and the second movable plate 322 to reciprocate in opposite directions.

[0068] The utility model further comprises a thread-feeding mechanism, which comprises a thread-releasing mechanism 21 and a thread-cutting mechanism 22 .

[0069] Figure 6The schematic diagram shows the overall structure of the pay-off mechanism 21 in the fully automatic wire harness threading and crimping plastic shell assembly equipment. The aforementioned pay-off mechanism 21 includes a support at the bottom, in which at least one active roller 211 and several driven rollers 212 are arranged. The active roller 211 rotates under the drive of the motor. When the drum wound with the wire harness is placed on the pay-off mechanism 21, the active roller 211 and the driven roller 212 can provide support for the drum, and when the motor is working, the active roller 211 starts to rotate, thereby driving the driven roller 212 to also start rotating under the action of the drum to carry out the wire feeding process.

[0070] The pay-off mechanism 21 is also provided with an adjustment assembly, which includes a bracket arranged on the same horizontal plane as the support. The bracket is provided with an accessible first storage wheel 213 and a second storage wheel 214. It is worth noting that the bracket is fixedly mounted on the slide rail based on its height direction. The first storage wheel 213 and the second storage wheel 214 are respectively arranged at the two ends of the slide rail, and the second storage wheel 214 is movably fixed on a slide that can reciprocate on the slide rail, so that the second storage wheel 214 can approach the first storage wheel 213. A plurality of wire grooves are provided on the aforementioned first storage wheel 213 and the second storage wheel 214. After the wire bundle is delivered, it is embedded in the embedding grooves 83 on the first storage wheel 213 and the second storage wheel 214 and fed into the cutting mechanism 22.

[0071] A position sensor is fixed on a section of the slide rail close to the second wire storage wheel 214, and a position sensor is also provided on the slide rail. The second wire storage wheel 214 can reciprocate between the position sensors, and the position sensors at both ends limit the movement range of the second wire storage wheel 214. The position sensor transmits the received position signal to the control terminal, and the control terminal adjusts the speed of the motor used to drive the active roller 211 according to the received position signal to achieve adjustment of the wire speed. Specifically, the wire harness output from the drum is wound into the wire grooves on the first wire storage wheel 213 and the second wire storage wheel 214, and then input into the cutting mechanism 22 to obtain wire harnesses of equal length for subsequent processing. Because the speed of the cutting mechanism 22 is constant, during the process of feeding the wire to the cutting mechanism 22, if the wire feeding speed is lower than the traction speed of the cutting mechanism 22, the second wire storage wheel 214 will gradually approach the first wire storage wheel 213 under the action of the wire harness until it is close to the position sensor in the middle section of the slide rail. At this time, after the position sensor receives the approach signal, it controls the motor to increase the speed to keep the position of the second wire storage wheel 214 between the position sensors at both ends. At this time, the position sensors at both ends cannot receive the position signal, which is the appropriate wire feeding speed, that is, the motor speed is within the appropriate threshold range; for example, when the position sensor at the lower end of the slide rail receives the position signal from the second wire storage wheel 214, it transmits the position signal to the control terminal, and the control terminal controls the motor speed to reduce the speed to keep the position of the second wire storage wheel 214 between the position sensors at both ends.

[0072] Figure 7 The schematic diagram shows the overall structure of the cutting mechanism 22 in the fully automatic wire harness threading and crimping plastic shell assembly equipment. Figure 7The content shown provides a specific description of the cutting mechanism 22. The cutting mechanism 22 includes a straightening and traction assembly fixedly mounted on the workbench 1, which is used to pull the wire bundle sent out by the wire-releasing mechanism 21 and straighten the wire bundle, including a straightening assembly and a traction assembly. The straightening assembly includes a plurality of rollers 221 distributed on both sides of the wire feeding path. A wire groove is provided on the outer edge of each roller 221. The spacing between adjacent rollers 221 on each side is the same, and the rollers 221 on both sides of the wire bundle are staggered so that the rollers 221 on both sides of the wire bundle can be precisely embedded in the spacing between adjacent rollers 221, thereby completing the straightening process of the wire bundle. The traction assembly includes tensioning belts 222 distributed on both sides of the wire feeding path. The tensioning belts 222 on both sides of the wire bundle are tightly fitted with the outer edge of the wire bundle, thereby completing the traction process of the wire bundle. It is worth noting that the aforementioned straightening assembly and traction assembly need to be able to adjust to a certain extent based on the width direction of the wire harness in order to adapt to the straightening and traction process of wire harnesses of different thicknesses. Therefore, slide rails are fixedly installed on the workbench 1 along its length direction, and the straightening assemblies and traction assemblies located on both sides of the wire harness are placed on the slide rails and adjusted by cylinders. Preferably, the slide rails and cylinders are only installed on one side of the aforementioned straightening assembly and traction assembly, and the position adjustment of the straightening assembly and traction assembly on the slide rails is completed by the extension and contraction of the cylinder.

[0073] The cutting mechanism 22 also includes an encoder assembly 223 and a pressure wheel 224, which are located at the output end of the straightening and traction assembly. A wire groove is also provided on the outer edge of the pressure wheel 224. After the wire harness is drawn out through the straightening and traction assembly, it is output through the encoder assembly 223 and the pressure wheel 224. The length of the wire harness is determined by the number of revolutions of the encoder. The cutting assembly, located at the output end of the encoder assembly 223, then completes the process of cutting the wire harness at a fixed distance. The cutting assembly can be directly driven by a pneumatic cylinder. During this process, the encoder transmits the length information of the wire harness to the control terminal, which then controls the cutting assembly to complete the process of cutting the wire harness at a fixed distance.

[0074] The system also includes a U-shaped mechanism 23, which includes a U-shaped clamping claw 233 for grabbing the wire harness output from the encoder assembly and between the pressure rollers. The U-shaped clamping claw 233 is fixed to a connecting rod 232, the other end of which is fixed to the rotating shaft of the U-shaped motor 231. The rotation of the U-shaped motor 231 drives the U-shaped clamping claw 233 to rotate to a certain extent. In actual application, that is, during wire feeding, the U-shaped clamping claw 233 grabs the front end of the wire harness, and the U-shaped motor 231 drives the U-shaped clamping claw 233 to rotate 180 degrees. After that, the clamping claw assembly 12 clamps the two ends of the wire harness.

[0075] The stripping mechanism is described in detail below. The stripping mechanism includes a core wire shaping mechanism 51 and an insulation layer stripping mechanism 52 , both of which are controlled by a control terminal.

[0076] Figure 8 The schematic diagram shows the overall structure of the core wire forming mechanism 51 in the fully automatic wire harness threading and crimping plastic shell assembly equipment. The core wire forming mechanism 51 includes a wire dividing mechanism for grabbing the inner core wires and a separation mechanism for separating adjacent inner core wires arranged close to the clamping jaw assembly 12, and the wire dividing mechanism and the separation mechanism can reciprocate in a direction perpendicular to the clamping jaw assembly 12. The wire-dividing mechanism includes a left wire-dividing clamp 511 and a right wire-dividing clamp 512 arranged side by side, which are used to clamp the left and right sides of the wire harness respectively. The aforementioned left wire-dividing clamp 511 and the right wire-dividing clamp 512 are fixedly arranged on a fixed frame, and the separation mechanism includes a separation claw 513 that can extend into the gap between the left wire-dividing clamp 511 and the right wire-dividing clamp 512. The separation claw 513 is driven by a cylinder to move into the gap between the left wire-dividing clamp 511 and the right wire-dividing clamp 512, that is, the separation claw 513 is fixedly arranged a certain distance above the aforementioned left wire-dividing clamp 511 and the right wire-dividing clamp 512. After the left wire-dividing clamp 511 and the right wire-dividing clamp 512 clamp the inner core wire of the wire harness, the separation claw 513 moves downward under the action of the cylinder to separate the separated inner core wire from the middle. It is worth mentioning that the aforementioned left branching jaw 511, right branching jaw 512 and separation jaw 513 can all reciprocate in a direction perpendicular to the jaw assembly 12. Specifically, the front and rear position adjustment of the branching mechanism is completed by setting the fixed frame provided with the left branching jaw 511 and the right branching jaw 512 as a whole on the electric cylinder. The electric cylinder is also fixed on another parallel electric cylinder. That is, after the aforementioned separation jaw 513 separates the inner core wire from the middle, the position of the left branching jaw 511 and the right branching jaw 512 can be adjusted by the movement of the electric cylinder. Under the pulling action of the left branching jaw 511 and the right branching jaw 512 and the blocking action of the separation jaw 513, the end of the inner core wire presents a vertical structure, and the inner core wire of the resulting wire harness exposed to the outside presents a Y-shaped structure. The aforementioned branching mechanism, separation mechanism and electric cylinder are all controlled by the control terminal.

[0077] Figure 9 The schematic diagram shows the overall structure of the insulation stripping mechanism 52 in the fully automatic wire harness threading and crimping plastic shell assembly equipment. The insulation stripping mechanism 52 includes a first cutter assembly 521 and a position adjustment assembly for adjusting the opening and closing of the first cutter assembly 521. The position adjustment assembly includes a servo motor and a screw rod coaxially fixed with the rotating shaft of the servo motor. Figure 10 The schematic diagram shows a partially enlarged structure of the first cutter assembly, as shown in FIG. Figure 10As shown, the first cutter assembly 521 includes an upper cutter and a lower cutter, and the upper cutter is fixed to the front side of the first bracket 522, and the lower cutter is fixed to the front side of the second bracket 523. The aforementioned screw rod passes through the thickness direction of the second bracket 523 and the second bracket 523 is threadedly engaged with the screw rod, so that when the screw rod rotates, the second bracket 523 can move toward the direction of the first bracket 522, thereby closing the first cutter assembly 521. When the servo motor is rotated in the opposite direction, the second bracket 523 can be moved away from the first bracket 522, completing the opening action of the first cutter assembly 521. In still other embodiments, the aforementioned screw is threadedly engaged with both the first bracket 522 and the second bracket 523, and the threads of the first bracket 522 and the second bracket 523 are in opposite directions. Thus, when the servo motor drives the screw to rotate, the first bracket 522 and the second bracket 523 can be simultaneously moved closer together. When the servo motor drives the screw to rotate in the opposite direction, the first bracket 522 and the second bracket can be simultaneously moved away from each other, thereby completing the opening and closing of the first cutter assembly 521. Alternatively, in still other embodiments, the opening and closing of the first cutter assembly 521 is directly driven by a pneumatic cylinder, with one of the upper cutter or the lower cutter being fixed to the end of the cylinder's telescopic rod, while the other is fixed. The movement of the cylinder's telescopic rod drives the upper and lower cutters toward or away from each other, thereby completing the opening and closing process of the first cutter assembly 521.

[0078] It is worth noting that the aforementioned first cutter assembly 521 includes a zero cutter 524 and a V cutter 525. The zero cutter 524 is attached to the rear side of the V cutter 525 and the zero cutter 524 fits tightly with the V cutter 525. During the process of stripping the insulation layer, the first cutter assembly 521 is closed under the action of the servo motor. The zero cutter 524 is used to cut off the front end of the inner core wire, so that the tails of the two inner core wires are in a flat state and the lengths of the two inner core wires are uniform. Then, the V cutter 525 is used to strip off the insulation layer outside the inner core wire, so that in the subsequent detection process, in the core wire number photo taken by the second CCD lens 71, the images of the two core wires are relatively consistent, which facilitates the core wire counting process.

[0079] A waste collection assembly is provided near the rear side of the aforementioned first cutter assembly 521, including a negative pressure tube 526 fixedly provided near the first cutter assembly 521, and a slot is provided on the side of the negative pressure tube 526 facing the back side of the first cutter assembly 521. The negative pressure set in the negative pressure tube 526 sucks the insulating sleeve stripped from the inner core wire into the negative pressure tube 526 to complete the collection of waste. In order to facilitate the stripping of the insulating sleeve on the inner core wire, the aforementioned first cutter assembly 521 and the servo motor are fixedly arranged on the support base, and the aforementioned support base is driven by a cylinder or an electric cylinder to reciprocate along the width direction of the workbench 1. When the first cutter assembly 521 is closed to a predetermined position under the action of the servo motor, the first cutter assembly 521 is driven by the cylinder or the electric cylinder to move toward the inner core wire away from the wiring harness, thereby stripping off the insulating sleeve wrapped around the inner core wire. The stripped insulating sleeve is then collected by the negative pressure tube 526. The aforementioned servo motor, cylinder or electric cylinder are all controlled by the control terminal.

[0080] Before or after stripping the insulation cover of the inner core wire, a process of inserting a waterproof plug into the inner core wire is also included, and a waterproof plug inserting mechanism 6 is used to insert a waterproof plug into the inner core wire. Figure 11 The schematic diagram shows the overall structure of the waterproof plug threading mechanism 6 in the fully automatic wire harness threading and crimping plastic shell assembly equipment. Figure 11 As shown, the waterproof plug threading mechanism 6 includes a vacuum suction nozzle 61 for obtaining the waterproof plug, and a transfer track 62 is fixedly provided below the output end of the vacuum suction nozzle 61 for transferring the waterproof plug obtained by the vacuum suction nozzle 61 to a predetermined work station. A limiting block 63 is fixedly provided at the end of the aforementioned transfer track 62 to limit the waterproof plugs located at different positions on the transfer track 62 to a fixed position to facilitate subsequent work steps.

[0081] A movable needle body is provided above the aforementioned limit block 63. The needle body can penetrate the hole in the center of the waterproof plug and temporarily fix the waterproof plug on the outer periphery of the needle body. The radius of the middle or upper part of the aforementioned needle body is larger than that of the lower end of the needle body, so that the waterproof plug can be limited to a fixed position on the needle body. The aforementioned needle body can be fixed to the end of the telescopic rod of a telescopic cylinder. The movement of the telescopic cylinder can press the needle body down to the position of the limit block 63, thereby accurately acquiring the waterproof plug and temporarily fixing it on the needle body. Alternatively, the aforementioned needle body can be fixed on the flip cylinder 64. The movement of the flip cylinder 64 can also press the needle body down to the position of the limit block 63, thereby accurately acquiring the waterproof plug and temporarily fixing it on the needle body.

[0082] Based on the above-mentioned needle body, a flip cylinder 64 is also provided below, and a tube body 65 is temporarily fixed on the flip cylinder 64. The tube body 65 is fixed in the flip cylinder 64 by snapping, and the tube body 65 is a hollow structure. The front end radius of the tube body 65 is smaller than the fixed part between the rear end of the tube body 65 and the flip cylinder 64. The front end of the needle body can be just embedded in the tube body 65, and the needle body is further driven to move by the above-mentioned telescopic cylinder or flip cylinder 64, so that the needle body is embedded in the tube body 65. Because the radius of the middle or upper part is larger than that of the lower part, the waterproof plug temporarily fixed on the needle body can be nested in the front end of the tube body 65.

[0083] The aforementioned tilting cylinder 64 is fixed to the track and can reciprocate along the width of the workbench 1 via the track. The tilting cylinder 64 can be driven by an electric cylinder or a pneumatic cylinder to move on the track. After the tilting cylinder 64 moves to the limit position, the tilting cylinder 64 rotates to a position where the tube 65 faces the clamping jaw assembly 12. At this point, a fixing claw 66 is fixedly provided, and the fixing claw 66 includes an upper half and a lower half. A semicircular hole groove is opened on the opposite side of the upper fixing claw 66 and the lower fixing claw 66. After the tube body 65 is inserted into the aforementioned hole groove, the upper fixing claw 66 and the lower fixing claw 66 can be closed under the action of the telescopic cylinder or the screw rod, thereby locking the waterproof plug located on the tube body 65. At this time, the clamping claw assembly 12 located in the front side of the fixing claw 66 will penetrate the inner core wire into the aforementioned hole groove, and due to the hollow structure of the tube body 65, the inner core wire can also be extended into the tube body 65. At this time, the tube body 65 withdraws backwards. Since the waterproof plug is fixed by the fixing claw 66, it will not shift due to the withdrawal of the tube body 65. After the tube body 65 is completely withdrawn, it can be directly fitted onto the inner core wire to complete the waterproof plug threading process.

[0084] The order of the aforementioned waterproof plug threading mechanism 6 and the insulation layer stripping mechanism 52 can be the waterproof plug threading mechanism 6 in front and the insulation layer stripping mechanism 52 in the back, or the insulation layer stripping mechanism 52 in front and the waterproof plug threading mechanism 6 in the back. The order does not affect the subsequent processing steps.

[0085] Figure 12 The overall structure of the core wire quantity detection module 7 in the fully automatic wire harness threading and crimping plastic shell assembly equipment is schematically shown. Figure 12 The core wire quantity detection module 7 is described in detail. The core wire quantity detection module 7 includes a second CCD lens 71 disposed facing the clamping jaw assembly 12 and movably fixed in a frame. A bowl light source 72 is further disposed between the second CCD lens 71 and the clamping jaw assembly 12. The bowl light source 72 is fixed by a pneumatic clamp fixed to the aforementioned frame. The distance between the second CCD lens 71 and the bowl light source 72 can be adjusted by a slide rail in the frame.

[0086] Figure 13 The schematic diagram shows the overall structure of the terminal crimping mechanism 8 in the fully automatic wire harness threading and crimping plastic shell assembly equipment, combined with Figure 13 The terminal crimping mechanism 8 is described in detail. The terminal crimping mechanism 8 includes a terminal feeding channel 81 for feeding strip terminals to the positioning mechanism. The output end of the terminal feeding channel 81 faces the positioning mechanism, and the crimping mechanism is fixedly arranged above the positioning mechanism. A feeding mechanism is also fixedly provided at the front end of the positioning mechanism, and the feeding mechanism includes a horizontally arranged telescopic cylinder, a slide rail is arranged parallel to the bottom of the telescopic cylinder, a fixed block is fixedly provided at the end of the aforementioned telescopic cylinder, and a slide groove is provided on the side of the fixed block facing the slide rail so that the fixed block can reciprocate along the length direction of the slide rail under the action of the telescopic cylinder, a connecting block is movably fixed at the end of the fixed block, and a clamping block 82 is vertically fixed at the end of the connecting block, and the clamping block 82 fits tightly on the platform for terminal transportation. Through the movement of the telescopic cylinder, the clamping block 82 can transport the strip-shaped terminal to the positioning mechanism. After the positioning mechanism fixes the terminal, the clamping block 82 is moved to the rear of the next terminal by the return stroke of the telescopic cylinder, so that when the telescopic cylinder moves next time, the clamping block 82 can deliver the next terminal to the specified position of the positioning mechanism, thereby ensuring the continuous progress of the terminal crimping process.

[0087] The positioning mechanism includes a wire-supporting clamp 122 fixed to the workbench 1 and a slot 83 adapted to the outer edge of the wire harness. After the wire harness is transferred to the specified position by the clamp assembly 12, the wire-supporting clamp 122 is used to straighten the wire harness and position the inner core wire in the slot 83 for positioning. The crimping mechanism includes a servo motor fixed above the positioning mechanism and a pressure block assembly. The servo motor controls the vertical movement of the pressure block assembly via a screw. Figure 14 The diagram schematically shows a partially enlarged structure of the pressing block assembly. The aforementioned pressing block assembly includes a pressing block 84 arranged at the front end and a cutter 85 fixedly attached to the rear side of the pressing block 84. A slot that adapts to the width of the wire harness is provided on the end of the aforementioned pressing block 84 and the cutter 85 facing the positioning mechanism. When the pressing block assembly is pressed down toward the positioning mechanism by the servo motor, the terminal sent to the inner core wire by the feeding mechanism is pressed down onto the inner core wire by the pressing block 84. As the pressing block assembly continues to be pressed down, the cutter 85 located behind the pressing block 84 cuts off the terminal, completing the terminal crimping process. During the crimping process, the feeding mechanism, the positioning mechanism, and the crimping mechanism are all controlled by the control terminal. There can be multiple terminal crimping stations, which are arranged in parallel on the workbench 1 and are used to crimp terminals of different shapes onto the inner core wire of the wiring harness.

[0088] Figure 15The overall structure of the terminal crimping condition detection module 9 in the fully automatic wire harness threading and crimping plastic shell assembly equipment is schematically shown. Figure 15 The terminal crimping condition detection module 9 is described in detail. It includes a positioning jaw positioned adjacent to the jaw assembly 12, which is used to secure the inner core wire of the crimped terminal. The positioning jaw is driven by a jaw cylinder. Lenses 91 and light sources 92 are fixedly mounted above and below the positioning jaw, respectively. A third CCD lens 93 is fixedly mounted above lens 91. This third CCD lens 93 transmits detection results to a control terminal for analysis of the terminal crimping condition.

[0089] Figure 16 The schematic diagram shows the overall structure of the molded shell plug-in mechanism 10 in the fully automatic wire harness threading and crimping molded shell assembly equipment, combined with Figure 16 The molded shell plug-in mechanism 10 is described in detail. The molded shell plug-in mechanism 10 includes a first positioning jaw 101 for grabbing the wiring harness terminal, and the first positioning jaw 101 is fixedly arranged facing the jaw assembly 12; it also includes a second positioning jaw 102 for grabbing the molded shell cavity, and the second positioning jaw 102 is arranged on the electric cylinder; the aforementioned first positioning jaw 101 is fixedly arranged at one end of the electric cylinder, and the other end of the electric cylinder is connected to the molded shell vibration disk 103 for feeding. The molded shell is fed after being arranged in a certain direction by the molded shell vibration disk 103. The second positioning jaw 102 and the other end of the electric cylinder clamp the molded shell, and then the second positioning jaw 102, under the action of the electric cylinder, approaches the first positioning jaw 101 and inserts the wiring harness terminal into the molded shell to complete the molded shell plug-in process. During the plug-in process, in some embodiments, a pressure sensor is set to monitor whether the molded shell and the terminal are assembled in place, and the monitoring results are transmitted to the control terminal for recording and judgment.

[0090] The NG cutting mechanism 11 is described in detail below. The NG cutting mechanism 11 includes a second cutter assembly and a wire take-up assembly arranged in sequence. Figure 17 The schematic diagram shows the overall structure of the second cutter assembly, which includes a fixed clamping cylinder and a zero cutter 524 respectively set on the upper and lower clamping jaws of the clamping cylinder. The movement of the clamping cylinder realizes the opening and closing of the zero cutter 524, thereby realizing the cutting process of the NG wire harness. After the NG wire harness is cut, it is transported by the movable clamping jaw 111 and moves to the wire take-up assembly. The overall structure of the wire take-up assembly is shown in FIG. Figure 18As shown. The movable jaw 111 can reciprocate to a certain extent along the length of the workbench 1. To achieve this motion, it can be fixed to a component such as an electric cylinder or a slide rail, which drives it to reciprocate along the length of the workbench 1. After the movable jaw 111 grasps the NG wire harness, the jaw assembly 12 releases, and the movable jaw 111 transfers the NG wire harness to the embedded groove 83 provided below the movable jaw 111. To facilitate the transfer of the NG wire harness by the movable jaw 111, it can also be fixed to a cylinder based on vertical reciprocating motion.

[0091] Figure 19 The schematic diagram shows the overall structure of the clamping jaw assembly 12 in the fully automatic wire harness threading and crimping plastic shell assembly equipment, combined with Figure 19 The clamping jaw assembly 12 is described in detail. The clamping jaw assembly 12 is a segmented structure, and the clamping jaw assembly 12 includes several groups of fixed clamping jaws 121 with fixed spacing, which are used to realize the position switching of the grasped wire harness between adjacent workstations. Each group of fixed clamping jaws 121 includes two clamping jaws with fixed spacing, which respectively grasp the two ends of the wire harness of equal length obtained by the cutting mechanism 22, and transport them to the next workstation. For example, after a group of clamping jaw assemblies 12 obtains the wire harness at the cutting mechanism 22, the clamping jaws close to the next workstation first move to the circumcision workstation to circumcision the end of the wire harness it has grasped, so that the inner core wire therein is exposed to the outside. After the inner core wires at both ends of this wire harness are exposed to the outside, the clamping jaw assembly 12 between the next workstations grasps it and transports it to the wire twisting mechanism 32 for the wire twisting process. It is worth mentioning that in order to facilitate the switching process of the above-mentioned clamping jaw assembly 12, a wire supporting clamping jaw 122 is fixedly provided at each work station, which is used to straighten the wire harness at the work station and fix it. After the wire supporting clamping jaw 122 fixes the wire harness, the clamping jaw assembly 12 located between the work stations can return to its original position to re-acquire the new wire harness and transfer it to the next work station.

[0092] In some embodiments, in order to reduce the control pressure of the control terminal, a PLC is used to control a single workstation. For example, the wiring harness sequence detection module 4 is set up, and the branching clamp 41 and the servo motor for controlling the rotation of the first rotating disk 42 are controlled by a separately set PLC controller. After the first CCD lens 44 transmits the captured wiring harness sequence image data to the control terminal, it determines whether the wiring harness sequence needs to be adjusted based on the image data results. If the wiring sequence harness needs to be adjusted, the instruction is sent to the corresponding PLC controller, and the servo motor is controlled by the PLC controller to complete the adjustment of the wiring harness sequence. For other components such as the stripping mechanism, the stripping mechanism, the core wire quantity detection module 7, the terminal crimping mechanism 8, the terminal crimping condition detection module 9, the molded shell plug-in mechanism 10 and the NG cutting mechanism 11, this method is used for control, which can greatly reduce the control terminal's participation in the control process of each subordinate workstation and reduce the control pressure of the control terminal. In the specific application process, the device server is constructed by applying the MES system, and the switch is used to enable the server terminal and the detection component to transmit and call data. In the present invention, the PLC controllers used are all purchased from KEYENCE.

[0093] The wire taking mechanism 13 is also included. The wire taking mechanism 13 includes a base, a positioning component is fixedly arranged on the base, and a clamp is fixedly arranged on the positioning component for grabbing the qualified wire harness product. In some embodiments, such as Figure 20 As shown, a slide bar is arranged perpendicular to the base, and the clamping claw is driven by a cylinder or an electric cylinder to reciprocate along the axial direction of the slide bar for positioning and transportation; in other embodiments, such as Figure 21 As shown, a sliding rod is also arranged horizontally perpendicular to the base, which is convenient for a driving part such as a servo motor or a swing cylinder arranged on the sliding rod to drive the connecting rod connected to it. A clamping claw for clamping the wiring harness is fixed on the connecting rod. The aforementioned driving part can complete its position adjustment on the sliding rod manually or by using a cylinder or electric cylinder.

[0094] When performing automated wire harness processing, the wire feeding mechanism automatically controls the wire harness pay-off speed, and the cutting mechanism 22 cuts the wire harness into wire harness segments of uniform length, which are clamped by the clamping claw assembly 12 and transferred to subsequent workstations for wire harness processing. First, it goes to the wire stripping mechanism, followed by the grain ring cutting mechanism 31 and the wire twisting mechanism 32 to expose the inner core wire inside the wire harness and twist it until it is flat. Then, the wire harness sequence detection module 4 is used to detect and adjust the sequence. Then, the inner core wire is adjusted to a set shape in the stripping mechanism to facilitate the subsequent insulation stripping and waterproof plug connection process. Then, the core wire quantity detection module 7 is used to complete the core wire quantity detection to determine whether the obtained core wire can be used in subsequent processing steps. Then, the terminal crimping and plastic shell plugging are completed, and the terminal crimping condition is detected by the terminal crimping condition. Finally, the qualified wire harness is taken out by the wire taking mechanism 13, and the unqualified wire harness is processed and collected by the NG cutting mechanism 11 to complete the entire wire harness automated processing process.

[0095] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
