Detailed Implementation
[0029] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings, but this utility model is not limited to the following embodiments.
[0030] In electronic components, pin 10 refers to the metal lead connecting the component to the circuit board. These pins are typically used for electrical signal transmission, power supply, grounding, and other functions between the component and the circuit board. Through these pins, components can connect to the circuit board, enabling communication and collaboration between electronic components.
[0031] Pins 10 in electronic components can have different shapes. Common shapes include through-hole pins 10 and bent pins 10. Through-hole pins 10 are typically upright metal leads used to insert into holes in the circuit board for connection. Bent pins 10 are typically bent metal leads used to connect components to the circuit board for special requirements, such as angular connections or space constraints.
[0032] During manufacturing and transportation, pin 10 may be bent or deformed due to collisions. Bent or deformed pin 10 will affect the contact of electrical signals and the transmission of data.
[0033] To solve the above problems, this utility model provides a pin straightening device, which includes a product carrier for loading pins 10, a carrier driver 11 for driving the product carrier to move, a straightening module for straightening pins 10, a straightening driver 12 for driving the straightening module to move, and a CCD module 13 for acquiring images of pins 10.
[0034] The correction module includes a correction head 14, which can contact the pins 10 on the product carrier. The correction driver 12 can drive the correction head 14 to move and adjust the shape of the pins 10 on the product carrier. The carrier driver 11 is used to adjust the relative position of the pins 10 on the product carrier and the correction module, so that a certain pin 10 on the product carrier is aligned with the correction head 14.
[0035] The CCD module 13 is positioned above the correction head 14 and is used to acquire images of the pins 10 to analyze the positional deviation of the pins 10.
[0036] In this embodiment, as Figure 1 , Figure 2 As shown, the product carrier is used to place the pins 10. The product carrier can place multiple pins 10 side by side. The multiple pins 10 are arranged along the length direction of the product carrier. The carrier driver 11 can drive the product carrier to move along the length direction of the product carrier.
[0037] like Figure 4 , Figure 5As shown, the straightening head 14 can move along the length of the needle 10. The needle 10 is generally made of a malleable metal material and is relatively thin, making it easy to bend under external force. In most cases, the needle 10 is bent to both sides along its length. The straightening head 14 is located on both sides of the needle 10, and when the straightening head 14 contacts the needle 10, it can push the needle 10 to the correct position.
[0038] CCD module 13, also known as a CCD camera, is a camera that uses a charge-coupled device (CCD) as its image sensor. A CCD is a semiconductor device that converts light signals into electrical signals and transmits image information to an electronic device for processing by reading it line by line.
[0039] In the industrial sector, CCD cameras are widely used in machine vision systems for automatic detection, measurement, and control.
[0040] CCD image analysis is used to detect deviations in product position, and includes the following steps: First, an image of the product is captured using a CCD camera. The image must be clear and well-lit for subsequent image processing and analysis. The acquired image is processed using image processing software, including image enhancement, edge detection, and feature extraction. These processing steps help to accurately identify the product's position and features. Based on the image processing, key features of the product, such as edges, corners, and center points, are extracted. These features can be used to describe the product's geometry and position. By comparing the difference between the product's actual position and its designed position, the deviation in product position is calculated. Position analysis and calculation can be implemented using mathematical algorithms or image processing techniques. Finally, the analysis results of the position deviation are transmitted to an execution device. The execution device can be the correction module in this embodiment.
[0041] In some embodiments, the carrier driver 11 and the correction driver 12 can be a linear motor, electric cylinder, hydraulic cylinder, pneumatic cylinder, or other drive device capable of linear movement.
