[0035] In addition, in order to better illustrate the present application, a large number of specific details are given in the specific embodiments below. Those skilled in the art should understand that without certain specific details, the present application can also be implemented. In some examples, methods, means, elements and circuits familiar to those skilled in the art are not described in detail, in order to highlight the main idea of the present application.

[0036] As shown in Figures 1-4 The PCB bow degree detection device of the embodiment of the present application comprises: a detection support 200, an adjusting support 300, a camera 100, a detection lamp 600 and a computer terminal. The camera 100 and the adjusting support 300 are respectively arranged at two ends of the detection support 200. The adjusting support 300 is suitable for arranging a circuit board to be detected. The shooting direction of the camera 100 is towards the adjusting support 300. The detection lamp 600 is arranged between the adjusting support 300 and the circuit board to be detected. The computer terminal is in communication connection with the camera 100 to obtain a shooting image.

[0037] In this specific embodiment, through the cooperation of the camera 100 and the computer terminal, automatic detection is realized, which greatly improves the detection speed compared with traditional manual detection and can meet the detection needs of large-scale production. In addition, through the cooperation of the detection support 200, the adjusting support 300 and the detection lamp 600, when the circuit board to be detected is placed on the detection plate body 220 of the detection support and the adjusting support 300, the detection lamp 600 is located between the detection support 200 and the adjusting support 300. When the bow degree of the circuit board meets the requirements, the light of the detection lamp 600 will not leak out from the position where the circuit board abuts against the detection plate body 220. When the bow degree of the circuit board does not meet the requirements, that is, the circuit board itself has a certain bending degree, the light of the detection lamp 600 will leak out from the position where the circuit board abuts against the detection plate body 220. In this way, it can be quickly detected and judged whether the bow degree of the circuit board meets the requirements.

[0038] Among them, the setting of the camera 100 can better capture whether the light of the detection lamp 600 leaks out from between the circuit board and the detection plate body 220.

[0039] In one specific embodiment, the detection support 200 includes a detection plate body 220 and a camera plate body 210. The camera plate body 210 is a long strip structure, one end of which is provided with a camera 100, and the other end is fixedly connected with the detection plate body 220. The detection plate body 220 is a long strip structure, which is arranged vertically to the length direction of the camera plate body 210, and the middle position of the detection plate body 220 is connected with the end of the camera plate body 210. The detection plate body 220 vertically extends a first lap plate 221, and the length direction of the first lap plate 221 is perpendicular to the length direction of the camera plate body 210, which supports the circuit board to be detected.

[0040] In this specific embodiment, the detection support 200 ensures the stable relative position relationship between the camera 100 and the circuit board to be detected, which is conducive to shooting an image that accurately reflects the bow degree of the circuit board. On the other hand, the setting of the first lap plate 221 facilitates the placement and fixation of the circuit board to be detected.

[0041] In one specific embodiment, the adjusting support 300 is arranged on the detection plate body 220, and the adjusting support 300 is a plate structure arranged vertically on the detection plate body 220, with the plate surface parallel to the first lap plate 221. The adjusting support 300 and the first lap plate 221 of the detection support 200 jointly support the two ends of the circuit board in the width direction. Among them, the top of the adjusting support 300 is flush with the top of the first lap plate 221, which facilitates the placement of the circuit board on the top of the first lap plate 221 and the adjusting support 300, increases the stability of the fixation of the circuit board, avoids the movement of the circuit board during the detection process, and ensures the accuracy of the detection result

[0042] Further, the top of the adjusting support 300 vertically extends a second clamping plate 310, which is a plate structure with a plate surface parallel to the plate surface of the first clamping plate 221, and the second clamping plate 310 is spaced apart from the top edge of the adjusting support 300 by a first preset distance. The second clamping plate 310 can abut one end of the circuit board, i.e., the two ends of the width of the circuit board can be located at the first clamping plate 221 and the top of the adjusting support 300, respectively. The second clamping plate 310 can further limit the position of the circuit board and improve the reliability of detection.

[0043] In a specific embodiment, the first clamping plate 221 is spaced apart from the adjusting support 300 by a second preset distance, and the detection lamp 600 is arranged between the first clamping plate 221 and the adjusting support 300. The installation position of the detection lamp 600 ensures that the light can fully and uniformly illuminate the circuit board, so that the image captured by the camera 100 can clearly reflect the surface features of the circuit board, which helps to more accurately analyze the bow degree of the circuit board.

[0044] In a specific embodiment, the adjusting support 300 is slidably arranged on the detection plate body 220, and the sliding direction is perpendicular to the length direction of the camera plate body 210. The slidable characteristic of the adjusting support 300 enables the detection device to adapt to circuit boards of different sizes, greatly improves the application range of the detection device, and reduces the cost of purchasing multiple detection equipment for detecting circuit boards of different sizes.

[0045] In a specific embodiment, the bottom of the length direction of the adjusting support 300 extends a moving part away from the second clamping plate 310, and the moving part is provided with a sliding block. The length direction of the detection plate body 220 is provided with a guide rail perpendicular to the length direction of the detection plate body 220, and the sliding block and the guide rail are matched. The adjusting support 300 is slidably connected with the guide rail of the detection plate body 220 through the sliding block. The cooperation of the sliding block and the guide rail makes the sliding operation of the adjusting support 300 more stable and accurate, which facilitates the operator to quickly adjust the position of the adjusting support 300 according to the size of the circuit board, and further improves the detection efficiency.

[0046] In this specific embodiment, the adjusting support 300 can slide along the length direction perpendicular to the circuit board, i.e., it can adapt to circuit boards of different width sizes for bow degree detection, and the top of the adjusting support 300 extends the second clamping plate 310, which can ensure that the circuit board is firmly located at the first clamping plate 221 and the top of the adjusting support 300.

[0047] In an embodiment, the outer side of the sliding block is provided with a push rod, and the length direction of the push rod is perpendicular to the sliding direction of the sliding block. The push rod provides a more convenient operation mode for the operator, reduces the operation difficulty, improves the efficiency of adjusting the position of the support 300, and further improves the efficiency of the entire detection process.

[0048] In an embodiment, the seat cushion 500 is provided, and the seat cushion 500 is in a plurality of rubber materials and is arranged at the bottom of the detection support 200. The seat cushion 500 reduces the influence of the device sliding or vibration on the detection result, and guarantees the accuracy and reliability of the detection process.

[0049] In an embodiment, the detection plate body 220 is in a hollow structure.

[0050] In an embodiment, the reinforcing plate 400 is provided, and the reinforcing plate 400 is in a plate structure with a right-angled triangle cross section. The reinforcing plate 400 is in two, and is fixedly connected with the camera plate body 210 and the detection plate body 220. The two reinforcing plates 400 fix the two ends of the detection plate body 220 in the length direction with the camera plate body 210, improve the structural strength and stability of the detection support 200, and make the detection device not easy to deform in the long-term use process, guarantee the performance of the detection device and the accuracy of the detection result.
