Description

TECHNICAL FIELD

[0001] The utility model relates to a carrying device field, concretely relates to a circuit board carrying device. BACKGROUND

[0002] In power modules, as power and power density increase, the size and weight of printed circuit boards (PCB) inside the power modules also increase significantly. Some heavy electronic components such as transformers, inductors, etc. are usually installed on the printed circuit board, and a large number of surface mount components (SMD components) are also installed on the front and back surfaces of the printed circuit board to form a printed circuit board assembly (PCBA). In the process of carrying, picking up and testing such large-size and heavy printed circuit boards or printed circuit board assemblies, the structure of the printed circuit board or printed circuit board assembly is easily damaged and the surface mount components are easily broken.

[0003] Specifically, when workers carry large-size and heavy printed circuit boards or printed circuit board assemblies, they can mainly adopt two carrying methods:

[0004] First, workers usually directly grab one pair of edges of the printed circuit board with both hands. However, due to uneven force on the edges, the weight of the remaining heavy areas of the printed circuit board can cause the printed circuit board to deform. The heavier the parts on the printed circuit board or the farther the installation position from the force point, the greater the deformation of the printed circuit board. In addition, when picking up the printed circuit board assembly, especially when carrying a heavy printed circuit board assembly, workers often need to use a large amount of force to lift it instantly, which can further exacerbate the deformation of the printed circuit board. If the deformation of the printed circuit board is too severe, the surface mount components may be damaged according to the force concentration, ultimately affecting the normal function of the printed circuit board assembly.

[0005] Second, workers grab large devices on the printed circuit board with both hands. In this case, due to the lever effect, other parts of the printed circuit board can still deform due to gravity, thereby damaging the surface mount components in the corresponding area. At the same time, the large devices grabbed need to bear the weight of the entire printed circuit board assembly, and the soldering leg parts of these large devices can appear tin cracks, causing the soldering points to fail, ultimately leading to functional failure of the printed circuit board assembly.

[0006] The circuit board assembly carrying frame currently on the market is mainly composed of a bottom plate and two side handles. When in use, the circuit board assembly is placed flat on the bottom plate, and the worker carries it through the handles. Since the circuit board assembly is placed flat on the bottom plate, it will not deform, and the carrying process does not need to directly contact the circuit board assembly, which can reduce the risk of deformation of the circuit board assembly. However, this type of carrying frame still has the following two significant shortcomings. First, when the circuit board assembly is placed on the carrying frame or taken off the carrying frame, there is still a risk of deformation and damage. These operation links may generate external force or deformation, causing damage to the surface mount components. Second, in the production, testing, spraying, dispensing, and assembly processes of the circuit board assembly, the carrying frame cannot participate in multiple process operations, so the circuit board assembly needs to be taken off the carrying frame multiple times to complete the relevant procedures and then placed back on the carrying frame. Frequent carrying and taking operations not only increase the workload, but also may cause damage to the circuit board assembly due to lack of adequate protection measures.

[0007] Therefore, it is necessary to develop a circuit board carrying device to solve the problems and defects faced by the prior art. Practical new type content

The rigid crossbar 2 also includes a first end 25 and a second end 26, wherein the first end 25 and the second end 26 are two opposite ends of the rigid crossbar 2.

[0105] In some embodiments, the circuit board assembly 20 includes a plurality of electronic components 206. A rigid crossbar 2 has a first distance D1 between itself and the surface 207 of the circuit board assembly 20. The tallest of the plurality of electronic components 206 has a second distance D2 between itself and the surface 207 of the circuit board assembly 20. Preferably, the first distance D1 is greater than the second distance D2. Specifically, the lengths of the quick-connect vertical bar 42 of the first connecting pin group and the hollow vertical bar 52 of the second connecting pin group 5 can be adjusted according to the height of the electronic components 206 on the circuit board assembly 20 to improve the usability flexibility of the circuit board handling device 100.

It should be emphasized that the structures of the two connecting components 1 can be the same or different. For example, the number and structure of the connecting feet of the two connecting components 1 can be the same or different, and can be adjusted and changed according to actual application requirements. This improves the application flexibility of the circuit board handling device 100c.
