Description

Technical Field

[0001] The utility model relates to the technical field of welding detection, in particular to an Xray nondestructive detection device for electronic welding detection. Background Art

[0002] Electronic components are basic elements in electronic circuits, usually individually packaged and have two or more leads or metal contacts. These metal contacts are connected by welding.

[0003] Electronic soldering is the process of connecting electronic components to circuit boards or other electronic components. It is one of the core processes in electronic assembly. It usually uses solder (such as tin-lead alloy) to achieve mechanical and electrical connections between metals. Electronic soldering is a key step in electronic assembly because it directly affects the performance, reliability and life of electronic equipment.

[0004] Electronic soldering inspection refers to the process of evaluating and inspecting the quality of solder joints during the electronics manufacturing process. This process is critical because it ensures that the mechanical and electrical connections of the solder joints meet the design requirements, thereby ensuring the performance and reliability of electronic devices.

[0005] CN219684210U in the prior art discloses an electronic component welding jig. By setting a detection camera, the electronic components can be magnified for detection through the detection camera, and the electronic components can be clearly detected, which can reduce the occurrence of rework. It solves the problem that the welded PCB board is sent to the detection point for detection, and rework and re-soldering are required after false soldering or leaking soldering is detected, which leads to a cumbersome process.

[0006] However, the above-mentioned prior art still has the following problems:

[0007] (1) The existing technology only performs surface inspection through inspection cameras and cannot detect whether there are defects inside the weld, resulting in the inability to ensure inspection efficiency;

[0008] (2) The prior art places the electronic components in the positioning grooves, which will cause slight vibration when the connecting frame is pushed to move, which may cause minor damage to the electronic components;

[0009] Therefore, there is an urgent need to improve the prior art to solve the above problems. Summary of the invention

[0010] The utility model overcomes the shortcomings of the prior art and provides an Xray nondestructive testing device for electronic welding detection.

[0011] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an Xray nondestructive testing device for electronic welding detection, comprising: a bracket, a placement part arranged on one side of the bracket, a sensing part and a detection part arranged on the other side of the bracket;

[0044] The design of the X-axis winding chain assembly 32 and the Y-axis winding chain assembly 33 enables flexible movement of the detection equipment in the X-axis and Y-axis directions, expanding the detection range. At the same time, the addition of the positioning sensor 34 further improves the detection accuracy, allowing the equipment to accurately align with the welding points that need to be detected, and effective detection can be achieved regardless of whether it is large or small electronic components.
