Description

Technical Field

[0001] This invention belongs to the field of peeling and cracking machine technology, specifically a positioning device for an intelligent terminal peeling and cracking machine based on laser coaxiality. Background Technology

[0002] Wire harnesses, as the "nerves and blood vessels" of modern electrical equipment and systems, are integrated connection components composed of multiple insulated wires bundled and wrapped together. They are widely used in automobiles, aerospace, home appliances, and various industrial equipment. The core process in the manufacturing of wire harnesses lies in the treatment of their terminals—that is, stripping the insulation layer from the end of each individual wire and crimping the metal connector. With the increasing complexity of end products, this poses unprecedented challenges to the efficiency, precision, and consistency of wire harness processing.

[0003] Currently, automated equipment for wire harness terminal processing mainly employs integrated stripping and crimping machines that combine the stripping and crimping units into a single unit. The workflow involves a robotic arm or wire feeding mechanism delivering a single wire at a time, sequentially completing length setting, stripping, crimping, and outputting the wire. While this method automates single-wire processing, it becomes problematic with multi-core wire harnesses due to structural limitations. The wire feeding and processing channels are single-line designs, unable to handle multiple parallel wires simultaneously. Operators must disassemble bundles of wires and feed them into the machine one by one. This process forces the high-speed machine to frequently wait for manual feeding, creating a production bottleneck. The labor intensity for workers is high, and the overall system efficiency is severely constrained by the manual feeding rhythm, failing to realize the high-speed potential of automated equipment and severely incompatible with the demands of mass production of multi-core wire harnesses. Therefore, we propose a laser coaxial intelligent terminal stripping and crimping machine positioning device. Summary of the Invention

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] In order to solve the problems in the background art, please refer to the following: Figure 1-5 A laser coaxial intelligent terminal stripping and cracking machine positioning device includes a worktable 100. An auxiliary plate 101 is fixedly connected to the upper side of the worktable 100. The auxiliary plate 101 facilitates the placement of the operator's arm and simultaneously shields the linear guide rail 310, improving the safety and comfort of the device. A terminal crimping machine 200, a moving device 300, and a wire stripping machine 400 are fixedly mounted on the upper side of the worktable 100. A first auxiliary device 500 and a second auxiliary device 600 are fixedly mounted on the upper side of the worktable 100. The first auxiliary device 500 is located below the terminal crimping machine 200, and the second auxiliary device 600 is located below the wire stripping machine 400. Measuring devices 700 are installed below both the terminal crimping machine 200 and the wire stripping machine 400. During use, the operator inserts multiple wires from a wire harness into the moving device. The wire harness enters the second auxiliary device 600, and then the wire stripper 400 is activated to strip the insulation from multiple wires in the harness simultaneously. After stripping, the moving device 300 is activated, which moves the harness to the left to the terminal crimping machine 200. Subsequently, the moving device 300, in conjunction with the terminal crimping machine 200, crimps the wires in the harness sequentially. During this process, two sets of measuring devices 700 detect the position of the harness at the terminal crimping machine 200 and the wire stripper 400, respectively. By setting the workbench 100, terminal crimping machine 200, moving device 300, wire stripper 400, first auxiliary device 500, second auxiliary device 600, and measuring device 700 to work together, multiple sets of wires in the harness can be stripped and crimped, thereby improving the speed and efficiency of wire terminal connection. Although the speed of terminal connection for a single set of wires is reduced by separating wire stripping and terminal crimping, the efficiency of stripping and crimping multiple sets of wires in the harness is improved.

[0020] The mobile device 300 includes a linear guide rail 310. A first fixing plate 320 is fixedly connected to the upper side of the linear guide rail 310. A first clamping block 330 is fixedly connected to the upper side of the first fixing plate 320. A first cylinder 340 is fixedly connected to the upper side of the first fixing plate 320. A second clamping plate 350 is fixedly connected to the telescopic end of the first cylinder 340. Limiting grooves are provided on opposite sides of the first clamping block 330 and the second clamping plate 350. During use, multiple wires of the wiring harness are placed on the upper side of the first clamping block 330. During this process, the wires are clamped by the first clamping block. The upper limit groove of 330 and the arc groove on the upper side of the first limit plate 610 are divided, so that the first cylinder 340 drives the second clamping plate 350 to press the upper side of the wire harness, so that the wire harness is fixed by the first clamping block 330 and the second clamping plate 350. Then, after the wire harness is stripped, it moves to the left to the terminal crimping machine 200 under the drive of the linear guide rail 310. The moving device 300 can be set to clamp the wire harness and move it, thereby improving the terminal connection speed of multiple wires in conjunction with the terminal crimping machine 200.

[0021] The second auxiliary device 600 includes a first limiting plate 610. The upper side of the first limiting plate 610 is uniformly provided with arc-shaped grooves. A second cylinder 620 is fixedly connected to the right side of the first limiting plate 610. The telescopic end of the second cylinder 620 is fixedly connected to the second limiting plate 630. When the second cylinder 620 is activated, it drives the second limiting plate 630 to assist in fixing the wire harness placed on the upper side of the first limiting plate 610. By setting the second auxiliary device 600 to assist in fixing the wire harness placed on the upper side of the first limiting plate 610, the speed and efficiency of subsequent wire stripping are improved.

[0022] The first auxiliary device 500 includes a frame 510, on the upper side of which a third cylinder 520 is fixedly connected. The third cylinder 520 is inclined, and a clamp 530 is fixedly connected to the telescopic end of the third cylinder 520. By setting the third cylinder 520 to drive the clamp 530 to fix the processed wire harness, it is easy to remove it from the moving device 300 to process the next set of wire harnesses. At the same time, it can also perform unloading work, which indirectly improves the efficiency and speed of wire harness connection terminals.

[0023] The measuring device 700 includes a third mounting plate 710, a high-resolution coaxial vision camera 720 fixedly connected to the upper side of the third mounting plate 710, a line laser scanner 730 fixedly connected to the upper side of the third mounting plate 710, and a high-precision point laser rangefinder 740 fixedly connected to the upper side of the third mounting plate 710. The high-resolution coaxial vision camera 720 is used for coarse positioning and feature recognition, and its optical path is coaxially integrated with the line laser scanner 730 and the high-precision point laser rangefinder 740: the line laser scanner 730 projects a line laser onto the target object to form a shape. The feature lines are used for three-dimensional contour scanning, and the high-precision point laser rangefinder 740 is used for absolute distance measurement. By setting the measuring device 700, the position of the wire harness can be detected, thereby effectively improving the stability of wire harness stripping and terminal connection. The clamp 530 includes a second fixing plate 531. The telescopic end of the second fixing plate 531 is fixedly connected to two sets of fourth cylinders 532. The opposite sides of the two sets of fourth cylinders 532 are fixedly connected to third clamping plates 533. By setting the fourth cylinders 532 to drive the third clamping plates 533, the wire harness is clamped and fixed.

[0024] The first mounting plate 321 is connected to the upper side of the first fixing plate 320. The first clamping block 330 is installed on the upper side of the first mounting plate 321. The telescopic end of the first cylinder 340 is fixedly connected to the second mounting plate 341. The second clamping plate 350 is located on the lower side of the second mounting plate 341. By setting the first mounting plate 321 and the second mounting plate 341, it is convenient for workers to install and replace the first fixing plate 320 and the second clamping plate 350, thereby improving the convenience of long-term use of this device.
