Description

Technical Field

[0001] This utility model relates to the field of terminal processing technology, specifically a terminal bending module. Background Technology

[0002] Terminal bending modules are specialized molds or module equipment used in fields such as electronic connectors and wire harness processing to precisely bend and shape metal terminals. Their core function is to process straight metal terminals into specific shapes through processes such as stamping and bending to meet electrical connection or assembly requirements.

[0003] Due to differences in raw material suppliers, fluctuations in production processes, and various factors during transportation and storage, the length of incoming terminal materials often has a certain error. This instability in length brings difficulties to subsequent bending processing, because the mold design is based on a specific terminal length. If the length of the incoming material does not meet the design requirements, the mold may not be able to clamp the terminal correctly, thus affecting the bending accuracy and consistency. Therefore, we need to propose a terminal bending module. Utility Model Content

A lower bending blade front and rear shaft is mounted on the top of the positioning base plate. A bending module left and right shaft is mounted on one side of the positioning base plate adjacent to the lower bending blade front and rear shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a bending module where the upper bending cutter moves along the front and rear axes to a suitable position. Then, the upper bending cutter moves along the upper and lower axes to press against the pre-bending point of the terminal. The lower bending cutter moves along the front and rear axes to the position where the terminal is to be bent. The terminal bending is completed by the lower bending cutter's front and rear axes and upper and lower axes moving together along a cam curve.

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

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] A terminal bending module includes a positioning base plate 1. A bending lower blade upper and lower shaft 2 is provided on the top of the positioning base plate 1. A bending upper blade upper and lower shaft 3 is provided on one side of the positioning base plate 1 located on the bending lower blade upper and lower shaft 2. A bending lower blade front and rear shaft 4 is installed on the top of the positioning base plate 1. A bending module left and right shaft 5 is installed on one side of the positioning base plate 1 located on the bending lower blade front and rear shaft 4. A bending module front and rear shaft 6 is installed on the bottom of the positioning base plate 1. After the bending upper blade 10 is moved to a suitable position by the bending module front and rear shaft 6, the bending upper blade 10 is pressed against the terminal pre-bending point by the bending upper blade upper and lower shaft 3. The bending lower blade 12 is moved to the terminal to be bent position by the bending lower blade 12. The terminal is bent 90° by the bending lower blade front and rear shaft 4 and the bending lower blade upper and lower shaft 2 moving together along a cam curve. This can further improve production efficiency and product quality.

[0021] In this embodiment, a terminal flow channel 7 is provided on the upper surface of the positioning substrate 1. A first visual inspection component 8 is provided on the front side of the terminal flow channel 7 for inspecting the terminal before bending. A second visual inspection component 9 is provided on the rear side of the terminal flow channel 7 for inspecting the bent terminal. To ensure the consistency of the terminal bending dimensions, the terminal is positioned and photographed before bending to determine the terminal bending point. In addition, after bending, to ensure the consistency of the terminal dimensions, visual inspection is used to inspect the dimensions of the bent terminal to ensure that the terminal dimensions are within the tolerance range. The terminal bending method of this utility model is simple and flexible, fast, reduces personnel input, and reduces operator fatigue, which is very beneficial to existing production needs.

[0022] Furthermore, the moving ends of the front and rear shafts 6 of the bending module are connected to the upper bending blade 10, and the positioning base plate 1 is fixedly connected to the limiting plate 11. The upper bending blade 10 is slidably connected to the limiting plate 11. By setting the limiting plate 11, the upper bending blade 10 is limited, making its movement process more stable and helping to further improve the stability of the device.

[0023] In addition, it also includes a bending cutter 12, which is connected to the moving end of the bending cutter front and rear shaft 4. The bending cutter 12 can be moved to the bending position of the terminal through the bending cutter front and rear shaft 4. The terminal is manually placed into the terminal flow channel 7, and then the terminal positioning hole is manually positioned. The mechanism automatically feeds the terminal and then performs the bending process.

[0024] Furthermore, the first visual inspection component 8 includes a first inspection camera 801, which is fixedly installed on the top of the terminal flow channel 7. A first positioning component 802 for fixing the terminal before bending is installed on one side of the first inspection camera 801 in the terminal flow channel 7. A first backlight 803 is provided on one side of the first positioning component 802. Through the coordinated use of the first inspection camera 801, the first positioning component 802, and the first backlight 803, the first inspection camera 801 converts the terminal to be inspected into an image signal, which is then transmitted to a dedicated image processing system for processing and analysis. The first inspection camera 801, as an image acquisition device, is responsible for capturing the image of the terminal. Its resolution, focal length, and other parameters need to be precisely adjusted according to the inspection requirements to ensure that the captured image is clear and accurate. The first positioning component 802 is used to ensure the positional accuracy of the terminal during the inspection process. The first backlight 803 provides stable and uniform illumination conditions to improve image quality and inspection accuracy, highlighting the contours and features of the terminal, allowing the inspection camera to capture the detailed information of the terminal more clearly.

[0025] Furthermore, the second visual inspection component 9 includes a second inspection camera 901, a second positioning component 902, and a second backlight 903. The second inspection camera 901, the second positioning component 902, and the second backlight 903 are all fixedly installed on the terminal flow channel 7. By setting the second inspection camera 901, the second positioning component 902, and the second backlight 903 to work together, the second inspection camera 901 captures terminal images under the illumination of the second backlight 903. The image signal is converted into a digital format and transmitted to the computer memory. The processor uses different algorithms to process the acquired images to improve image quality and extract effective information. These algorithms include noise reduction, contrast enhancement, edge detection, etc. The processor identifies and quantifies key features in the image, such as the size, shape, and position of the terminal. These feature data are transmitted to the control program for further analysis. The control program determines whether the terminal meets the quality standard based on the received feature data. If it does not meet the standard, it issues an alarm signal or executes corresponding control commands (such as rejecting defective products) to ensure that the terminal size is within the tolerance range.
