Description

Technical Field

[0001] This utility model relates to the field of wire harness processing, and in particular to a high-efficiency wire harness crimping quality inspection device. Background Technology

[0002] In the modern electronics and electrical manufacturing industry, wire harnesses, also known as cable assemblies or wiring harnesses, are key components that connect various electronic components and realize power transmission and signal interaction. Their quality and production efficiency are directly related to the performance and reliability of the entire electronic product.

[0003] Existing wire harness crimping typically relies on manual operation or semi-automatic equipment. After crimping, additional quality inspection equipment is required to inspect the crimped wire harness, which not only increases the complexity of the operation and extends the production cycle, but also increases crimping costs and affects production efficiency. Furthermore, current feeding usually relies on electronic components to drive automatic feeding, which increases energy consumption and costs, making it very inconvenient to use.

[0004] Therefore, it is necessary to design a high-efficiency wire harness crimping quality inspection device that can automatically feed terminals while crimping wires and terminals to form wire harnesses and perform quality inspection, without the need for electronic components, thereby reducing energy consumption and costs, improving the efficiency of wire harness crimping, and being easy to use. Utility Model Content

This eliminates the need for electronic components for feeding, reduces energy consumption and costs, improves wire harness crimping efficiency, and is easy to use.

[0011] Preferably, the conveyor belt is equipped with multiple partitions.

[0012] This utility model has the following advantages: 1.

[0021] A high-efficiency wire harness crimping quality inspection device, such as Figures 1-5 As shown, the assembly includes a base 1, a display screen 2, a fixing frame 3, a multi-stage cylinder 4, a connecting frame 5, a lower pressing mold 6, an upper pressing mold 7, a pressure sensor 71, a vision camera 10, a clamping assembly, and a conveying assembly. The base 1 is U-shaped for easy support. The display screen 2 is connected to the upper part of the base 1. The fixing frame 3 is connected to the upper side of the lower part of the base 1. The multi-stage cylinder 4 is connected to the lower side of the upper part of the base 1. The connecting frame 5 is connected to the rear part of the fixing frame 3. The lower pressing mold 6 is placed on the upper side of the fixing frame 3. The telescopic end of the multi-stage cylinder 4 passes through the connecting frame 5 and is connected to the upper pressing mold 7. The pressure sensor 71 is connected to the lower side of the upper pressing mold 7. The vision camera 10 is connected to the lower front side of the connecting frame 5. The fixing frame 3 has clamping assemblies on both the left and right sides for clamping and fixing the lower pressing mold 6. The fixing frame 3 has a conveying assembly for conveying the wire harness.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, the clamping assembly includes a clamping frame 8 and a first spring 81. The clamping frame 8 is slidably connected to both the left and right sides of the fixed frame 3. The clamping frame 8 is engaged with the lower pressing mold 6. Each clamping frame 8 has a handle on the side that is far apart from each other, so that it is easy to hold and pull the clamping frame 8 to move. The clamping frame 8 is connected to the fixed frame 3 by two first springs 81, one above the other.

[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the conveying assembly includes a conveyor belt 9, an extrusion frame 11, a second spring 12, a guide frame 121, a limiting block 122, a third spring 123, and a common cylinder 13. The upper part of the fixed frame 3 is rotatably equipped with two left and right rollers, and the conveyor belt 9 is wound between the rollers. The conveyor belt 9 is equipped with sixteen partitions to facilitate the separate conveying of wire harness components. The guide frame 121 is connected to the rear right side of the fixed frame 3. The extrusion frame 11 is slidably connected to the guide frame 121. The second spring 12 is connected between the extrusion frame 11 and the guide frame 121. The limiting block 122 is slidably connected to the lower right part of the extrusion frame 11. The third spring 123 is connected between the limiting block 122 and the extrusion frame 11. The common cylinder 13 is connected to the upper rear side of the fixed frame 3.

[0024] This device can be used when wire harness crimping requires quality inspection. The base 1 is U-shaped and contacts a table or ground surface for easy support. Multiple terminals are placed on the conveyor belt 9, separated by partitions. The lower crimping mold 6 then contacts the fixing frame 3, and is pushed to move and contact the clamping frame 8. The lower crimping mold 6 continues to move, causing the clamping frame 8 to return to its original position and engage with the lower crimping mold 6. The first spring 81, after being compressed, rebounds, thus fixing the lower crimping mold 6. This allows for simultaneous installation and fixing of the lower crimping mold 6 during wire harness crimping, preventing displacement and facilitating crimping. The loading and unloading of the lower crimping mold 6 improves the stability of crimping. Then, the handheld wire is brought into contact with the lower crimping mold 6. Next, the ordinary cylinder 13 is activated, and its telescopic end moves to push the terminal onto the wire, making the terminal contact the lower crimping mold 6. Then, the ordinary cylinder 13 reverses its operation, causing its telescopic end to retract. The ordinary cylinder 13 is then closed, and the multi-stage cylinder 4 is activated. The multi-stage cylinder 4 drives the upper crimping mold 7 to move and press the wire and terminal, achieving efficient crimping of the wire harness. Simultaneously, the pressure sensor 71 comes into contact with the wire and terminal, detecting the pressure during the crimping process. The movement of the upper crimping mold 7 compresses the crimping frame 11, causing it to move along the guide frame 121. The second spring 12 is compressed, causing the limiting block 122 to move and contact the partition. The limiting block 122 then moves along the crimping frame 11 and resets. The third spring 123 is compressed and then rebounds. After crimping, the multi-stage cylinder 4 reverses its operation, causing the upper crimping mold 7 and the pressure sensor 71 to move in opposite directions and reset. Then, the vision camera 10 inspects the appearance defects and dimensional accuracy of the wire harness, thus achieving quality inspection of the wire harness crimping. The inspection data is displayed on the display screen 2. Next, the wire harness is removed. Simultaneously with the upper crimping mold 7 resetting, the second spring 12 returns to its original position. When the extrusion frame 11 moves in the reverse direction to reset, the limiting block 122 moves in the reverse direction to reset, pushing the partition to move, causing the conveyor belt 9 to rotate, causing the roller to rotate, and then conveying the next terminal to the front of the ordinary cylinder 13. Then, the above operation is repeated, and the hand-held wire is brought into contact with the lower crimping mold 6, and the terminal is pushed to move for crimping and inspection until the wire harness processing is completed. This allows for the automatic feeding of terminals while crimping wires and terminals to form wire harnesses and performing quality inspection, without the need for electronic components for feeding, reducing energy consumption and cost, improving the efficiency of wire harness crimping, and making it easy to use. Then, the multi-stage cylinder 4, the pressure sensor 71, the vision camera 10, and the ordinary cylinder 13 can be turned off.
