Description

Technical Field

[0001] This invention relates to the technical field of material handling mechanisms, and more specifically to an automatic material handling device for wire harness crimping. Background Technology

[0002] During the production process, wire harnesses typically require stripping, cutting, and terminal crimping. When crimping wire harnesses, a material handling device is used to transfer the wire harness from the previous station to the crimping device for crimping, and then the crimped wire harness is transferred to the next station. Since sometimes incomplete crimping or inadequate crimping may occur, transferring unqualified wire harnesses to the next station after crimping may affect the quality of the final product.

[0020] like Figure 1-6 As shown, the present invention provides an automatic material handling device for crimped wire harnesses, including a first driving device 1 and a second driving device 2, as well as a feeding mechanism 6 and a detection mechanism 7. The first driving device 1 is mounted on a mounting frame 3 and is used to drive the mounting plate 4 at its bottom to rotate. The second driving device 2 is mounted on a mounting frame 5 at the front of the mounting frame 3 and is used to drive the mounting plate 51 at its bottom to rise, fall, and rotate. The feeding mechanism 6 is mounted on the mounting plate 4 and the mounting plate 51 and is used to remove the crimped wire harness from the crimping device. The detection mechanism 7 is mounted on the mounting plate 51 and is used to detect the firmness of the terminals on the wire harness.

[0021] It should be noted that the feeding mechanism 6 includes a first finger cylinder 61, a second finger cylinder 64, and a double-rod cylinder 65. There are two first finger cylinders 61, which are symmetrically arranged on the front side of the mounting plate 1 4. The Y-shaped gripper of the first finger cylinder 61 is provided with a connecting plate 62, and the connecting plate 62 is provided with a curved clamping block 63. One of the second finger cylinders 64 is provided on the mounting plate 2 51. The double-rod cylinder 65 is provided on the mounting plate 2 51 and its piston rod end is provided with a moving frame 66. The other second finger cylinder 64 is provided on the moving frame 66. Each second finger cylinder 64 has an L-shaped plate 67 on its parallel gripper.

[0022] Furthermore, the detection mechanism 7 includes a clamping plate 71, a push plate 76, a displacement sensor 75, and a pressing plate 77. The clamping plate 71 is slidably connected to a guide rod 72 on the side of the L-shaped plate 67. The guide rod 72 has a cuboid structure, and a baffle 721 is provided at the outer end of the guide rod 72. A spring 73 is sleeved between the clamping plate 71 and the baffle 721. A V-groove 711 is provided on the side of the clamping plate 71. A detection plate 74 is slidably connected to the front side of the clamping plate 71. The displacement sensor... Sensor 75 is mounted on clamping plate 71 and its detection end is connected to detection plate 74. Detection plate 74 has a V-groove 741 on its side. Push plate 76 is mounted on the side of clamping plate 71 and its lower end is slidably connected to slide rod 761 on the side of mounting plate 51. Spring 762 is sleeved on slide rod 761. Extrusion plate 77 is mounted on moving frame 66 and has an extrusion slope 771 on its side. Push plate 76 has a drive slope 763 on its side that cooperates with drive slope 763.

[0023] In addition, several curved clamping blocks 63 are provided and evenly distributed along the connecting plate 62, and the wire harness is clamped by the curved clamping blocks 63 on the connecting plate 62.

[0024] Detailed implementation methods and principles:

[0025] In practical application, the first driving device 1 drives the first finger cylinder 61 to rotate to the previous working position. The Y-shaped gripper on the first finger cylinder 61 drives the connecting plate 62 to rotate. The curved clamping block 63 on the connecting plate 62 clamps the wire harness. Then, the first driving device 1 drives the wire harness to rotate to the crimping device to crimp the terminals of the wire harness. After crimping, the first driving device 1 drives the crimped wire harness to rotate directly above the second finger cylinder 64 on the mounting plate 51. Then, the second driving device 2 controls the second finger cylinder 64 to move upward, so that the L-shaped plate 67 on the second finger cylinder 64 is positioned between the two connecting plates 62. The second finger cylinder 64 drives the L-shaped plate 67 to clamp the wire harness. At the same time, the V-groove 711 on the clamping plate 71 and the V-groove 741 on the detection plate 74 clamp the wire harness, but both can slide on the wire harness. The curved clamping block 63 on the connecting plate 62 of the first finger cylinder 61 releases the wire harness. Then, the second drive device 2 controls the second finger cylinder 64 to move downward. Next, the piston rod of the double rod cylinder 65 retracts, driving the moving frame 66 to move closer to the mounting plate 51, so that the two wire harnesses are paralleled. During the movement of the moving frame 66, the pressing slope 771 of the pressing plate 77 on it drives the push plate 76 to move outward along the slide rod 761 on the side of the mounting plate 51, so that the clamping plate 71 moves on the guide rod 72. The spring 73 on the guide rod 72 is compressed. When the detection plate 74 on the clamping plate 71 contacts the terminal on the wire harness, the displacement sensor 75 measures the displacement generated when the detection plate 74 is pressed against the terminal to detect whether the terminal is installed firmly. After the moving frame 66 moves to the appropriate position, the second drive device 2 drives the detected wire harness to the next station.

[0026] In summary, this invention, by setting a detection mechanism 7 on the feeding mechanism 6, allows the wire harness on the moving frame 66 to be paralleled with the wire harness on the mounting plate 51. During this process, the pressing plate 77 drives the pushing plate 76 to move the clamping plate 71 along the wire harness. The detection plate 74 on the clamping plate 71 measures the displacement generated when the detection plate 74 is pressed against the terminal by the displacement sensor 75 to detect whether the terminal is securely installed. The entire process integrates wire harness feeding and wire harness terminal security detection, with a high degree of automation, thereby improving the processing efficiency of the wire harness.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the present invention and technical solution to other situations without modification, are all within the protection scope of the present invention.
