Description

Technical Field

[0001] This utility model relates to the technical field of soldering quality inspection machines, and in particular to a multi-angle soldering quality inspection machine. Background Technology

[0002] In the field of flexible printed circuit board (FPC) and connector soldering processes, solder quality is a key factor affecting the electrical connectivity and long-term reliability of electronic components. Currently, the industry generally adopts a combined quality inspection model that combines two-dimensional automated optical inspection (AOI) equipment with manual visual inspection to ensure soldering quality.

[0003] However, existing 2D AOI systems can only perform planar imaging of solder joints. This results in blind spots during inspection, where solder joints in areas obscured by other components or the internal structure of the connector cannot be effectively inspected. Therefore, these blind spots require manual re-inspection. Operators need to use magnifying glasses or microscopes to check each point in the blind spots. This process is not only time-consuming and labor-intensive, but the results are also highly susceptible to the operator's experience and fatigue, leading to missed or incorrect assessments. With the continuous development of electronic technology, electronic devices are trending towards miniaturization and high-density interconnection. Against this backdrop, the limitations of traditional inspection methods in terms of inspection field of view and accuracy are becoming increasingly apparent, making it difficult to meet the practical needs of accurately evaluating miniature solder joints from all angles.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0015] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0017] Please see Figures 1 to 6 The multi-angle soldering quality inspection machine according to one embodiment of the present invention includes a machine body 10, a conveying component 20 installed on the machine body 10, and a vision inspection component 30 installed above the conveying component 20.

[0018] The conveying assembly 20 includes a double-row synchronous belt conveyor 21 mounted on the body 10, multiple pressure blocks 22 mounted on the top of opposite ends of the double-row synchronous belt conveyor 21, floating beams 23 slidably connected to the inner walls of opposite sides of the double-row synchronous belt conveyor 21, multiple push blocks 24 spaced apart on the top of the floating beams 23, push cylinders 25 mounted on the bottom of opposite sides of the double-row synchronous belt conveyor 21, blocking cylinders 26 mounted on the inner walls of opposite sides of the outlet end of the double-row synchronous belt conveyor 21, and blocking plates 27 respectively mounted above each blocking cylinder 26; the piston rod of the push cylinder 25 is connected upward to the floating beams 23.

[0019] In this embodiment, the synchronous belt 210 of the double-row synchronous belt conveyor 21 is used to transport the pallet 40 between the synchronous belt 210 and the pressure block 22. The pallet 40 is used to place the FPC product to be inspected. The two ends of the floating beam 23 are slidably connected to the inner wall of the double-row synchronous belt conveyor 21 by guide rail pairs, which are arranged vertically.

[0020] During operation, the blocking cylinder 26 first drives the blocking plate 27 upward, which abuts against one end of the tray 40, preventing the tray 40 from flowing to the next process with the synchronous belt 210. Next, the pushing cylinder 25 drives the floating beam 23 upward, which in turn drives the pushing block 24 upward to abut against and push the tray 40 upward, clamping the tray 40 between the pushing block 24 and the pressure block 22 to fix its position, facilitating inspection by the subsequent visual inspection component 30. After inspection, the pushing cylinder 25 and the blocking cylinder 26 are reset, releasing the tray 40 so it can flow to the next process with the synchronous belt 210.

[0021] The vision inspection component 30 includes a gantry 31 mounted on one side of the double-row synchronous belt conveyor 21, a five-axis robot 32 mounted on the gantry 31, a bracket 33 mounted on the five-axis robot 32, and a vision module mounted on the bracket 33. The vision module is located above the double-row synchronous belt conveyor 21. Driven by the five-axis robot 32, the vision module can perform multi-angle visual inspection of the FPC products on the tray 40, which greatly improves the inspection accuracy.

[0022] In this embodiment, combined with Figure 1 and Figure 6 To understand, the five-axis robot 32 includes an XYZ three-axis linear module mounted on a gantry 31, a first electric rotary platform 321 connected to the end of the XYZ three-axis linear module, and a second electric rotary platform 322 connected to the rotor of the first electric rotary platform 321; the rotor of the second electric rotary platform 322 is used to connect to a bracket 33. The rotation axis of the first electric rotary platform 321 is parallel to the vertical direction, and the rotation axis of the second electric rotary platform 322 is perpendicular to the vertical direction.

[0023] In this embodiment, please refer again. Figure 6 The vision module includes a CCD camera 34 mounted on a bracket 33, a magnifying lens 35 coaxially connected to the CCD camera 34, and a ring light source 36 coaxially mounted at the end of the magnifying lens 35.

[0024] The aforementioned multi-angle soldering quality inspection machine has a simple structure and is easy to use. A five-axis robot 32 and a vision module are set above the double-row synchronous belt conveyor 21. By utilizing the five-axis degrees of freedom of the five-axis robot 32, the vision module can easily perform multi-angle visual inspection of the FPC products on the tray 40, which not only greatly improves the inspection accuracy but also significantly enhances the inspection efficiency.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
