Description

Technical Field

[0001] This invention relates to the field of wire harness testing equipment technology, and in particular to a wire harness terminal cross-sectional testing and analysis device. Background Technology

[0002] With the continuous development of wire harness technology and the increasing importance of wire harness terminals for product safety, various industries have higher and higher requirements for the quality of wire harness terminals. By analyzing the process characteristics of wire harness terminals, it has been found that they are characterized by small size, high requirements for dimensional accuracy, geometric tolerances, cross-sectional quality, and large batch production. During the processing, defects such as chip skipping, fan-shaped defects, and uneven spacing may occur. Cross-sectional analysis is an important means of verifying crimping quality at the microscopic level, a point that has been increasingly recognized by industry professionals.

[0003] Existing wire harness cross-section inspection devices are all split-type structures. Operators first place the fixture holding the wire harness on the cutting and grinding equipment for cutting and grinding. After completion, the fixture is removed and placed under the inspection lens for inspection. The whole process requires manual intervention, which is not efficient and affects production efficiency. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a wire harness terminal cross-section inspection and analysis device to solve the problem that split-type inspection equipment requires manual operation and has low inspection efficiency.

[0005] To achieve the above objectives, the present invention provides a wire harness terminal profile inspection and analysis device, comprising a housing, a rotating plate disposed in the middle of the housing, a moving mechanism disposed on the rotating plate, a clamping mechanism disposed on the moving mechanism, the clamping mechanism clamping the wire harness terminal, and the moving mechanism driving the clamping mechanism to move; a cutting and grinding mechanism disposed on one side of the housing, the cutting and grinding mechanism cutting and grinding the clamped wire harness terminal; an image acquisition lens mounted on the other side of the housing; a display disposed on one side of the housing; a partition disposed in the middle of the housing, the partition having a rotating opening in the middle corresponding to the rotating plate, and a baffle adapted to the rotating opening disposed in the middle of the rotating plate.

[0006] A further improvement is that the cutting and grinding mechanism includes a cutting motor and a grinding motor that are fixedly mounted side by side on the side wall of the housing. A cutting disc is installed at the output end of the cutting motor, and a grinding disc is installed at the output end of the grinding motor.

[0007] A further improvement is that the moving mechanism includes a guide seat fixedly mounted on a rotating plate, a first movable seat slidably mounted on the guide seat, a guide groove formed on the guide seat, a first screw rotatably mounted in the guide groove, a first slider threadedly connected to the first screw, the first slider being fixedly connected to the first movable seat, a first motor mounted on one end of the guide seat, the output end of the first motor being connected to the first screw, a guide hole formed on the first movable seat, a guide post slidably disposed in the guide hole, a second movable seat fixedly connected to the end of the guide post, a second motor mounted on the first movable seat, a gear mounted on the output end of the second motor, and a rack fixedly connected to one side of the first movable seat, the gear and rack meshing.

[0008] A further improvement is that the clamping mechanism includes a clamping seat, a fixed clamping block is fixedly installed on one side of the clamping seat, a movable clamping block is slidably installed on the other side of the clamping seat, and a clamping screw is threadedly installed on the clamping seat, with the end of the clamping screw rotatably connected to the movable clamping block.

[0009] A further improvement is that the second movable seat has a convex structure, a slot is provided at the front end of the second movable seat, a clamping block is fixedly connected to one side of the clamping seat, the clamping block is adapted to the slot, and a locking bolt is threaded on one side of the front end of the second movable seat, with the end of the locking bolt extending into the slot.

[0010] A further improvement is that a lead screw is installed inside the housing near the image acquisition lens, a third motor is installed on one side of the housing, the output end of the third motor is connected to the lead screw, a moving block is threaded onto the lead screw, a limit groove is opened at the bottom of the housing, the lower end of the moving block is slidably set in the limit groove, a placement shell is installed on one side of the moving block, and a wiping pad is placed inside the placement shell.

[0011] A further improvement is that a storage shell is fixedly installed inside the housing at the end of the lead screw. A liquid filling groove is opened at the upper end of the storage shell, and water-absorbing cotton is installed on one side of the storage shell. A liquid filling hole is opened at the bottom of the liquid filling groove, and a ball bearing is installed in the liquid filling hole.

[0012] A further improvement is that a rotating motor is installed at the bottom of the housing, and the output end of the rotating motor is connected to the rotating plate.

[0013] The beneficial effects of this invention are as follows: By setting a cutting and grinding mechanism and an image acquisition lens on both sides of the housing, and a rotating plate in the middle of the housing, the wire harness terminals are clamped by a clamping mechanism and placed on the rotating plate. As the rotating plate rotates, the wire harness is cut and ground on one side of the cutting and grinding mechanism, while the image acquisition lens on the other side captures the end face image of the cut wire harness terminal. The rotation enables the switching of processing positions, greatly improving the switching efficiency between different processing steps and improving the detection efficiency. Furthermore, a lead screw drives a moving block to move, and a wiping plate is placed on the moving block through a housing. The wiping plate wipes the cut and ground wire harness terminal cross-section as the moving block moves, making it easier for the image acquisition lens to capture images more clearly and effectively, thus improving the detection effect.

The rack 23 moves back and forth with the rotation of the gear 22. The guide post 19 slides in the guide hole 18 with the second movable seat 20 to ensure the smooth movement of the second movable seat 20.

[0024] The clamping mechanism includes a clamping seat 24.

The wire harness terminal is placed between the fixed clamping block 25 and the movable clamping block 26. By rotating the clamping screw 27, the clamping screw 27 pushes the movable clamping block 26 to move, thereby clamping the wire harness terminal in the middle between the fixed clamping block 25 and the movable clamping block 26.

[0025] The second movable seat 20 has a convex structure. A slot 28 is provided at the front end of the second movable seat 20. A clamping block 29 is fixedly connected to one side of the clamping seat 24. The clamping block 29 is adapted to the slot 28. A locking bolt 30 is threadedly installed on one side of the front end of the second movable seat 20. The end of the locking bolt 30 extends into the slot 28. The clamping seat 24 is installed on the second movable seat 20 by being inserted into the slot 28 through the clamping block 29. By rotating the locking bolt 30, the locking bolt 30 abuts against the clamping block 29, thereby locking.

[0026] A lead screw 31 is installed inside the housing 1 near the image acquisition lens 3. A third motor 32 is installed on one side of the housing 1. The output end of the third motor 32 is connected to the lead screw 31. A moving block 33 is threaded onto the lead screw 31. A limit groove 34 is opened at the bottom of the housing 1. The lower end of the moving block 33 is slidably disposed in the limit groove 34. A placement shell 35 is installed on one side of the moving block 33. A wiping plate 36 is placed inside the placement shell 35. When the rotating plate 2 drives the clamping mechanism to rotate the wire harness terminal to the side of the image acquisition lens 3, the third motor 32 drives the lead screw 31 to rotate. The moving block 33 slides along the limit groove 34 through the rotation of the lead screw 31. The moving block 33 drives the wiping plate 36 in the placement shell 35 to wipe the wire harness terminal.

[0027] A housing 37 is fixedly installed inside the housing at the end of the lead screw 31.

A liquid filling hole 40 is provided at the bottom of the liquid filling tank 38, and a ball bearing 41 is installed inside the hole 40. As the wiping blade 36 moves into the housing 37, the upper end of the wiping blade 36 contacts the ball bearing 41, causing the ball bearing 41 to rotate. The corrosive cleaning solution in the liquid filling tank 38 is released into the tank as the ball bearing 41 rotates. The cleaning fluid drips from the hole 40 onto the wiping pad 36, which absorbs the corrosion cleaning fluid to facilitate subsequent corrosion cleaning of the wire harness terminal cross-section. After the wiping pad 36 has completely moved into the housing 37, it stops pushing the ball 41 to roll, and the ball 41 blocks the liquid filling hole 40, stopping the corrosion cleaning fluid from dripping. A water-absorbing cotton 39 is installed on one side of the housing 37, which absorbs the residual corrosion cleaning fluid flowing out of the liquid filling hole 40.

[0028] During processing, the wire harness terminal is placed on the clamping seat 24, and the clamping screw 27 is rotated to make the movable clamping block 26 cooperate with the fixed clamping block 25 to clamp and fix the wire harness terminal. The clamping block 29 of the clamping seat 24 is inserted into the slot 28 on the second moving seat 20 and the locking bolt 30 is tightened to fix it. When the equipment is started, the first motor 17 drives the first screw 15 to rotate, which adjusts the position of the first moving seat 13 left and right. The second motor 21 drives the gear 22 to rotate, which makes the second moving seat 20 move back and forth with the rack 23, thereby moving the clamped wire harness terminal closer to the cutting disc 10 for cutting, and then closer to the grinding disc 11 for grinding. After cutting and grinding, the rotating motor 42 drives the rotating plate 2 to move, so that the cut and ground wire harness terminal is moved to the side of the image acquisition lens 3. The third motor 32 drives the lead screw 31 to rotate, and the moving block 33 moves left and right with the rotation of the lead screw 31. The wiping plate 36 wipes and cleans the cut surface of the wire harness terminal with the movement of the moving block 33. The image acquisition lens 3 acquires images of the cut surface of the wire harness terminal. The detection and analysis system performs data analysis based on the acquired images. The acquired images and analyzed data are displayed on the display 4. The operator makes a judgment based on the image and data structure of the wire harness.
