Description

Technical Field

[0001] This application relates to the field of wire harness processing, and in particular to an automated welding device for wire harness ends. Background Technology

[0002] In modern industrial production, the connection process between wire harnesses and terminals is a crucial step in the manufacturing of many electrical equipment.

[0003] In traditional wire harness and terminal welding operations, the industry typically uses welding machines. During operation, workers manually align the wire harness and terminal on a support platform, then start the welding machine, which automatically completes the welding. This process requires workers to expend time and effort to position the wire harness and terminal accurately to ensure welding quality. Furthermore, the entire welding process, from wire harness preparation to terminal placement, relies on manual operation, making the whole process quite cumbersome. Utility Model Content

[0004] To facilitate the welding of wire harnesses and their ends, this application provides an automated welding device for wire harness ends.

[0005] This application provides an automated welding equipment for wire harness ends, which adopts the following technical solution: An automated welding equipment for wire harness ends includes a first slide rail and a wire harness reel. A first mechanical gripper is fixedly installed on the top side of the first slide rail, which is used to transport the first mechanical gripper. A cable conveyor, a wire stripper, and a support platform are sequentially arranged along one side of the first slide rail. The cable conveyor is used to transport the wire harness. A support sleeve for threading the wire harness is installed at the end of the cable conveyor near the first slide rail. A first cylinder is fixedly installed on the support sleeve, and a wire cutter is fixedly installed on the first cylinder. An end conveyor and a welding machine are arranged on the support platform. A robotic arm is installed on the side of the first slide rail away from the welding machine, and a second mechanical gripper is fixedly installed on the robotic arm.

[0006] By adopting the above technical solution, after the cable conveyor transports the wire harness, the wire harness exits from the support sleeve. The first slide rail transports the first mechanical gripper, which clamps the wire harness exiting from the support sleeve. The first cylinder drives the wire cutter to cut the wire harness exiting from the support sleeve. Subsequently, the first slide rail drives the first mechanical gripper to move the wire harness to the wire stripper for stripping. After stripping, the end conveyor provides the end, and the second mechanical gripper transfers the end from the end conveyor to the support platform. The first slide rail, through the first mechanical gripper, transports the wire harness to the support platform, and the welding machine is started to complete the welding of the wire harness and the end. This automates the welding of the wire harness end, eliminating the need for manual placement of the wire harness and end, and improving welding efficiency.

[0007] Optionally, two conductive plates are fixedly installed on the top side of the support platform. The conductive plates are located downstream of the welding machine process. A detector is installed on the side of the support platform away from the first slide rail, and the conductive plates are electrically connected to the detector.

[0008] By adopting the above technical solution, after welding is completed, the wire harness and the end are moved to the conductive plate. The detector performs electrical testing on the wire harness and the end through the two conductive plates, which can easily determine the welding quality.

[0009] Optionally, a rotating groove is provided on the top side of the support platform. The rotating groove is located between two conductive plates. Two rotating rods are rotatably installed inside the rotating groove. Each of the two rotating rods is fixedly installed with a rotating plate and a gear. The two gears mesh with each other. One of the rotating rods is connected to a first motor.

[0010] By adopting the above technical solution, the two rotating rods installed in the rotating groove, through gear meshing, cause the two rotating plates to rotate in opposite directions under the drive of the first motor, which can clamp the wire harness and the end welding joint, thereby adjusting the position of the wire harness end after welding.

[0011] Optionally, a second slide rail is provided on the side of the first slide rail away from the support platform, and a third mechanical gripper is installed on the second slide rail.

[0012] By adopting the above technical solution, when the detector detects an electrical problem with the wire harness and the end, the third mechanical gripper on the second slide rail can remove the wire harness and the end from the first mechanical gripper, which facilitates subsequent processing of the problematic wire harness and end.

[0013] Optionally, a support frame is provided at the end of the support platform. The support frame is located downstream of the welding machine process. An insulating film take-up reel and a fixing rod are fixedly installed on the support frame. The insulating film take-up reel is located above the support platform, and the fixing rod is located below the support platform. The insulating film take-up reel is used to hold the rolled insulating film. The free end of the insulating film is fixedly connected to the fixing rod. The insulating film take-up reel is connected to a second motor. The support frame is equipped with two sets of hot-cutting components for cutting the insulating film. A heater is provided on the side of the support frame away from the welding machine.

[0014] By adopting the above technical solution, after the welding machine completes the welding of the wire harness and the end, the insulating film reel on the support frame releases the insulating film under the drive of the second motor. The insulating film covers the welded wire harness end through the clearance opening. The hot cutting component cuts the insulating film, and the heater heats the insulating film to make it fit tightly against the wire harness end. This realizes the automation of the insulation treatment of the welded part of the wire harness end, and improves the efficiency and quality of insulation treatment.

[0015] Optionally, the hot cutting assembly includes a second cylinder and a hot cutting blade, wherein the second cylinder is fixedly mounted on the support frame, and the hot cutting blade is connected to the second cylinder.

[0016] By adopting the above technical solution, the second cylinder of the hot cutting component can drive the hot cutting blade to cut the insulating film, and the cut insulating films can be connected to each other when heated.

[0017] Optionally, the first cylinder and the tangent are located on the top side of the support sleeve, and the top side of the support sleeve has an opening for the tangent to pass through.

[0018] By adopting the above technical solution, when cutting the wire harness, the cutting blade enters the support sleeve from the through-hole to cut the wire harness, and the bottom inner wall of the support sleeve supports the wire harness, which facilitates the cutting of the wire harness.

[0019] Optionally, the support sleeve has a discharge port on the side of the sleeve near the wire stripper for the wire harness to be removed.

[0020] By adopting the above technical solution, the discharge port facilitates the movement of the wire harness toward the wire stripping machine.

[0021] In summary, this application includes at least one of the following beneficial technical effects: The first mechanical gripper is conveyed by the first slide rail, the cable conveyor conveys the wire harness, the first cylinder drives the wire cutter to cut the wire harness, the first slide rail then drives the first mechanical gripper to move the wire harness to the wire stripper for stripping, the end conveyor provides the end, the second mechanical gripper transfers the end to the support platform, the first slide rail conveys the wire harness to the support platform through the first mechanical gripper, and finally the welding machine is started to complete the welding, thus facilitating the welding of the wire harness and the end; An insulating film take-up reel holds the rolled insulating film, and a second motor drives the reel to rotate, allowing the insulating film to cover the welded wire harness ends. A hot-cutting component on the support frame can cut the insulating film, and a heater on the side of the support platform away from the wire stripper can heat the insulating film. This achieves automated operation of wire harness end insulation protection, improves production efficiency, and ensures the quality of insulation protection. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses an automated welding device for wire harness ends.

[0026] Reference Figure 1 An automated welding device for wire harness ends includes a first slide rail 1 and a wire harness take-up reel 2 disposed on one side of the first slide rail 1. A cable conveyor 3, a wire stripper 4, and a support platform 5 are sequentially arranged along the process path on the side of the first slide rail 1 near the take-up reel. A first mechanical gripper 6 is fixedly installed on the top side of the first slide rail 1, and the first slide rail 1 is used to convey the first mechanical gripper 6.

[0027] Reference Figure 1 , Figure 2 The conveying direction of the cable conveyor 3 is perpendicular to the conveying direction of the first slide rail 1. A support sleeve 7 is fixedly installed at one end of the cable conveyor 3 near the first slide rail 1. The wire harness take-up reel 2 is used to hold the coiled wire harness, which is pulled out from the wire harness take-up reel 2 and enters the cable conveyor 3. The cable conveyor 3 conveys the wire harness through the support sleeve 7. Then, the first slide rail 1 moves the first mechanical gripper 6 to the position of the support sleeve 7, and the first mechanical gripper 6 clamps the wire harness extending from the support sleeve 7.

[0028] A first cylinder 8 is fixedly installed on the top wall of the support sleeve 7, and the first cylinder 8 extends and retracts along the height direction. A wire cutter 9 is fixedly installed on the piston rod of the first cylinder 8. A through-hole 10 is opened on the top wall of the support sleeve 7 for the wire cutter 9 to enter the interior of the support sleeve 7.

[0029] Reference Figure 1 , Figure 2After the first mechanical gripper 6 clamps the wire harness extending from the support sleeve 7, the first cylinder 8 is activated. The first cylinder 8 enters the support sleeve 7 through the port 10, thereby completing the cutting of the wire harness. Cutting the wire harness inside the support sleeve 7 allows the inner wall of the bottom side of the support sleeve 7 to support the wire harness, thus facilitating the cutting blade 9 to cut the wire harness. In another embodiment, the cutting blade 9 can cut at the end of the support sleeve 7 away from the cable conveyor 3.

[0030] The support sleeve 7 has a discharge port 11 on the side of the cylinder wall near the wire stripper 4 for the wire harness to be removed. After the wire harness is cut, the first slide rail 1 moves the wire harness from the support sleeve 7 to the wire stripper 4. The discharge port 11 facilitates the removal of the wire harness from the support sleeve 7.

[0031] After the first slide rail 1 moves the wire harness from the support sleeve 7 to the wire stripper 4, the wire stripper 4 strips the outer insulation layer from one end of the wire harness.

[0032] Reference Figure 1 An end-cap conveyor 12 and a welding machine 13 are installed on the side of the support platform 5 away from the first slide rail 1. A robotic arm 14 is installed on the side of the first slide rail 1 away from the welding machine 13, and a second mechanical gripper 15 is fixedly mounted on the robotic arm 14. End caps are placed at intervals on the end-cap conveyor, and the robotic arm 14 drives the second mechanical gripper 15 to move and pick up the end caps from the end-cap conveyor 12, and then place the end caps on the support platform 5. After the end caps are placed on the support platform 5, the first mechanical gripper 6 places the stripped wire harness on the support platform 5, with the wire harness overlapping the end caps. Then the welding machine 13 welds the end caps and the wire harness.

[0033] Reference Figure 3 A magnetic block 16 is embedded on the top side of the support platform 5. The magnetic block 16 is used to attract the end, thereby playing a temporary fixing role.

[0034] Reference Figure 1 , Figure 3 , Figure 4 Two conductive plates 17 are fixedly installed on the top side of the support platform 5, and the conductive plates 17 are located downstream of the welding machine 13 in the process. A detector 18 is set on the side of the support platform 5 away from the first slide rail 1, and the conductive plates 17 are electrically connected to the detector 18. A rotating groove 19 is opened on the top side of the support platform 5, and the rotating groove 19 is located between the two conductive plates 17. Two rotating rods 20 are rotatably installed inside the rotating groove 19. Each of the two rotating rods 20 is fixedly installed with a rotating plate 21 and a gear 22. The two gears 22 mesh with each other, and one of the rotating rods 20 is connected to the first motor 23.

[0035] After the wire harness and end are welded, the first slide rail 1 moves the wire harness and end to the conductive plate 17 via the first mechanical gripper 6. The first motor 23 is then started, causing the two rotating rods 20 to rotate in opposite directions. This causes the two rotating plates 21 to clamp the welded portion of the wire harness and end, aligning them correctly. The two rotating plates 21 then return to the rotating groove 19. After the two rotating plates 21 return to the rotating groove 19, the detector 18 tests the conductivity of the wire harness and end.

[0036] Reference Figure 1 A second slide rail 24 is provided on the side of the first slide rail 1 away from the support platform 5, and a third mechanical gripper 25 is installed on the second slide rail 24. When the detector 18 detects that the conductivity between the wire harness and the end does not meet the requirements, the third mechanical gripper 25 clamps the wire harness, the first mechanical gripper 6 releases the wire harness, and then the second slide rail 24 drives the third mechanical gripper 25 to move away from the first slide rail 1, thereby removing the damaged wire harness and end for recycling.

[0037] Reference Figure 1 , Figure 5 A support frame 26 is provided at the end of the support platform 5, and the support frame 26 is located downstream of the process where the testing instrument 18 is located. An insulating film take-up reel 27 and a fixing rod 28 are fixedly installed on the support frame 26. The insulating film take-up reel 27 is located above the support platform 5, and the fixing rod 28 is located below the support platform 5. The insulating film take-up reel 27 is used to hold the rolled insulating film, and the free end of the insulating film is fixedly connected to the fixing rod 28. A second motor 29 is connected to the insulating film take-up reel 27. A heater 30 is installed on the side of the support frame 26 away from the welding machine 13. Two sets of hot cutting assemblies 31 are installed on the support frame 26. The hot cutting assembly 31 includes a second cylinder 311 and a hot cutting blade 312. The second cylinder 311 is fixedly installed on the support frame 26, and the hot cutting blade 312 is connected to the cylinder.

[0038] After verifying that the electrical properties between the wire harness and the end meet the requirements, the first slide rail 1, via the first mechanical gripper 6, drives the wire harness to continue moving. The welded portion between the wire harness and the end then comes into contact with the insulating film. Simultaneously, the second motor 29 drives the insulating film reel 27 to unwind. Next, the second cylinder 311 is activated to drive two hot-cutting blades 312 to move. The two hot-cutting blades 312 cut the insulating film and heat it, causing the insulating film to adhere to each other. The wire harness and end, covered with the insulating film, are then fed into the heater 30. The heater 30 heats the insulating film, causing it to shrink and tighten around the welded portion between the wire harness and the end.

[0039] The implementation principle of an automated wire harness end welding device according to an embodiment of this application is as follows: A first slide rail 1 conveys a first mechanical gripper 6, which clamps the wire harness passing through a support sleeve 7. A first cylinder 8 drives a wire cutter 9 to cut the wire harness passing through the support sleeve 7. Subsequently, the first slide rail 1 drives the first mechanical gripper 6 to move the wire harness to the wire stripper 4 for wire stripping. After stripping, the end conveyor 12 provides the end, and a second mechanical gripper 15 transfers the end from the end conveyor 12 to the support platform 5. The first slide rail 1 conveys the wire harness to the support platform 5 through the first mechanical gripper 6, and the welding machine 13 is started to complete the welding of the wire harness and the end, thereby realizing the automation of wire harness end welding.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
