Technical Field

[0001] This utility model relates to the field of solder joint detection technology, specifically to an image acquisition device for solder joints of electronic components. Background Technology

[0002] In the electronics manufacturing industry, solder joint quality directly affects the reliability and stability of products. For example, as a core component of electronic devices, PCB (Printed Circuit Board) defects (such as cold solder joints, missing solder joints, bridging, etc.) can lead to short circuits, signal transmission interruptions, and even safety accidents. With the miniaturization and high-density development of electronic products (such as the reduction of solder joint spacing in mobile phone chips to the micrometer level), higher requirements are placed on the accuracy, efficiency, and automation of solder joint inspection. Electronic component solder joint image acquisition devices are commonly used, but existing devices still have certain shortcomings, such as:

[0003] Application CN201920381080.8, entitled "A Solder Joint Image Acquisition Device," includes a fixture frame and a host computer. The fixture frame has a workspace containing a product positioning platform, a track, a fixed bracket, and an image acquisition device. The product positioning platform has a positioning groove that matches the shape of the product to be inspected. The track is mounted above the product positioning platform. The fixed bracket is slidably mounted on the track, and the image acquisition device is fixed to the fixed bracket. The host computer is signal-connected to the image acquisition device and receives the solder joint information acquired by the image acquisition device. This device suffers from drawbacks when dealing with the different outlines of various circuit boards, which may lead to incompatibility of the positioning grooves and require frequent fixture changes, affecting production line efficiency and failing to meet usage requirements. Therefore, this paper proposes an electronic component solder joint image acquisition device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an electronic component solder joint image acquisition device to solve the problem mentioned in the background art that existing electronic component solder joint image acquisition devices may not be universal for different types of circuit boards with different outlines, requiring frequent tooling changes and affecting production line efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a worktable, a sampling robotic arm assembly, and a transmission motor. The lower ends of the sampling robotic arm assembly and the transmission motor are fixedly connected to the upper end of the worktable. A turntable is fixedly connected to the upper end of the worktable, and an annular slide rail is provided on the upper end of the turntable. A positioning post is slidably connected to the annular slide rail, and a limit gear is fixedly connected to the upper end of the positioning post. A small gear is fixedly connected to the shaft end of the upper end of the transmission motor, and the small gear meshes with the limit gear for transmission.

[0006] The above technical solution facilitates precise positioning and image acquisition of electronic components;

[0007] As a preferred embodiment of this utility model, a boss is provided at the center of the upper end face of the limiting gear, and an annular retaining seat is fixedly connected to the center of the upper end face of the boss; a plurality of limiting posts are slidably connected to the annular retaining seat, and the limiting posts are evenly distributed about the center of the annular retaining seat.

[0008] The above technical solution allows for flexible adjustments based on electronic components of different sizes, thereby improving the accuracy and efficiency of image acquisition.

[0009] As a preferred embodiment of this utility model, a locking post is fixedly connected to the upper end face of the limiting post, and an arc-shaped sliding groove corresponding to the locking post is provided on the limiting gear.

[0010] By adopting the above technical solution, the arc-shaped sliding groove design makes the limiting column more stable during movement, avoiding image acquisition errors caused by improper position adjustment, and further improving the accuracy and stability of image acquisition.

[0011] As a preferred embodiment of this utility model, silicone protective sleeves are fixedly connected to the inner end faces of the limiting posts.

[0012] By adopting the above technical solution, scratches or wear on the surface of electronic components are prevented during clamping, effectively protecting the integrity of electronic components. At the same time, the stability of electronic components during image acquisition is ensured, preventing image blurring or distortion due to external factors, and further improving the quality of image acquisition.

[0013] As a preferred embodiment of this invention, the sampling robotic arm assembly comprises a base, a robotic arm, and a data acquisition camera; the lower end face of the base is fixedly connected to the upper end face of the worktable, and the lower end face of the robotic arm is fixedly connected to the upper end face of the base; the data acquisition camera is fixedly connected to the end of the robotic arm.

[0014] The above technical solution facilitates the adjustment of the position and angle of the acquisition camera to accommodate electronic components of different sizes and shapes, ensuring that the acquired solder joint images are clear and complete.

[0015] As a preferred embodiment of this invention, the lower end face of the workbench is provided with support legs, and the lower end face of the support legs is provided with anti-slip pads.

[0016] By adopting the above technical solution, the device can maintain stability in different working environments, preventing it from tipping over or shifting due to uneven or slippery ground, thus ensuring the continuity and stability of the image acquisition process. At the same time, the anti-slip pad design increases the friction between the device and the ground, further improving the device's anti-slip ability and making the entire device safer and more reliable during use.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the device realizes accurate and rapid positioning and image acquisition of electronic components on different types of circuit boards without frequent tooling changes, which greatly improves production line efficiency; at the same time, the design of structures such as limiting gears, limiting columns and arc-shaped slides allows the device to be flexibly adjusted according to electronic components of different sizes, which improves the accuracy and stability of image acquisition.

[0018] 1. During use, the operator places the electronic component on the turntable and then starts the drive motor. The drive motor drives the pinion to rotate, and the pinion meshes with the limit gear to drive the limit gear to rotate (the positioning post slides synchronously along the annular slide rail on the turntable with the limit gear). The limit gear drives the locking post to move through the arc-shaped slide groove. The locking post drives the limit post to move towards the center of the limit gear teeth until the silicone protective sleeve at the end of the limit post contacts the electronic component. This prevents the electronic component from shifting during image acquisition, ensuring the accuracy of image acquisition. At the same time, the silicone protective sleeve protects the surface of the electronic component, preventing scratches or damage caused by direct contact and ensuring the integrity of the electronic component. Subsequently, the position and angle of the acquisition camera on the sampling robotic arm assembly are adjusted to ensure that the acquired solder joint image is clear (the sampling robotic arm assembly is a mature technology in the existing market. For the fixation of different electronic components, sensors can be added to the worktable to prevent the electronic component from being over-clamped by the limit post). Attached Figure Description

[0027] Please see Figures 1-6 The present invention provides a device for acquiring images of solder joints of electronic components, comprising a worktable 1, a sampling robotic arm assembly 2, and a drive motor 3. The lower ends of the sampling robotic arm assembly 2 and the drive motor 3 are fixedly connected to the upper end of the worktable 1. The device is characterized in that: a turntable 4 is fixedly connected to the upper end of the worktable 1, and an annular slide rail is provided on the upper end of the turntable 4; a positioning post 5 is slidably connected to the annular slide rail, and a limit gear 6 is fixedly connected to the upper end of the positioning post 5; a small gear 7 is fixedly connected to the shaft end of the upper end of the drive motor 3, and the small gear 7 and the limit gear 6 mesh for transmission, facilitating precise positioning and image acquisition of electronic components.

[0028] A boss is provided at the center of the upper end face of the limiting gear 6, and an annular bracket 8 is fixedly connected at the center of the upper end face of the boss; multiple limiting posts 9 are slidably connected on the annular bracket 8, and the limiting posts 9 are evenly arranged about the center of the annular bracket 8, which facilitates flexible adjustment according to electronic components of different sizes, thereby improving the accuracy and efficiency of image acquisition.

[0029] The upper end face of the limiting post 9 is fixedly connected to the locking post 10, and the limiting gear 6 is provided with an arc-shaped sliding groove corresponding to the locking post 10. The design of the arc-shaped sliding groove makes the limiting post 9 more stable during movement, avoiding image acquisition errors caused by improper position adjustment, and further improving the accuracy and stability of image acquisition.

[0030] Silicone protective sleeves are fixedly connected to the inner end faces of the limiting posts 9 to prevent scratches or wear on the surface of electronic components during clamping, effectively protecting the integrity of electronic components and ensuring the stability of electronic components during image acquisition. This prevents images from becoming blurry or distorted due to external factors, further improving the quality of image acquisition.

[0031] The sampling robotic arm assembly 2 consists of a base 201, a robotic arm 202, and a camera 203. The lower end face of the base 201 is fixedly connected to the upper end face of the worktable 1, and the lower end face of the robotic arm 202 is fixedly connected to the upper end face of the base 201. The camera 203 is fixedly connected to the end of the robotic arm 202, which facilitates the adjustment of the position and angle of the camera 203 to accommodate electronic components of different sizes and shapes, ensuring that the acquired solder joint images are clear and complete. At the same time, this design makes the overall structure of the sampling robotic arm assembly 2 compact and stable, improving the efficiency and accuracy of image acquisition.

[0032] The lower end face of the worktable 1 is equipped with support legs, and the lower end face of the support legs is equipped with anti-slip pads, which makes it easy for the device to maintain stability in different working environments and prevent the device from tipping over or shifting due to uneven or slippery ground, thus ensuring the continuity and stability of the image acquisition process. At the same time, the design of the anti-slip pads increases the friction between the device and the ground, further improving the device's anti-slip ability and making the entire device safer and more reliable during use.

[0033] Working principle: During use, the operator places the electronic component on the turntable 4, then starts the drive motor 3. The drive motor 3 drives the pinion 7 to rotate, and the pinion 7 drives the limit gear 6 to rotate through meshing with the limit gear 6 (the positioning post 5 slides synchronously along the annular slide rail on the turntable 4 with the limit gear 6). The limit gear 6 drives the locking post 10 to move through the arc-shaped slide groove. The locking post 10 drives the limit post 9 to move towards the center of the limit gear 6 until the silicone protective sleeve at the tail end of the limit post 9 contacts the electronic component, preventing the electronic component from shifting during image acquisition and ensuring the accuracy of image acquisition. At the same time, the design of the silicone protective sleeve protects the surface of the electronic component, avoiding scratches or damage caused by direct contact and ensuring the integrity of the electronic component. Subsequently, the position and angle of the acquisition camera 203 on the sampling robotic arm assembly 2 are adjusted to ensure that the acquired solder joint image is clear (the sampling robotic arm assembly 2 is a mature technology in the existing market. For the fixation of different electronic components, sensors can be added to the workbench 1 to prevent the electronic component from being over-clamped by the limit post 9).
