Description

Technical Field

[0001] This utility model belongs to the field of FPC circuit board testing technology, and specifically relates to an FPC circuit board quality testing device. Background Technology

[0002] FPC circuit board quality inspection equipment refers to a series of professional equipment used to inspect and evaluate the appearance, structure, electrical performance, and function of flexible printed circuit boards to ensure that they meet quality standards and design requirements. These typically include optical inspection equipment, electrical performance testing equipment, tensile testing machines, and bending testing machines.

[0003] When using a bending tester to inspect the quality of FPC circuit boards, it is necessary to consider the variability of ambient temperature in actual use scenarios. Bending testers usually cannot control the temperature during bending. Temperature has a significant impact on the material properties and bending performance of FPC circuit boards. At different temperatures, the mechanical properties of the substrate and cover film of FPC circuit boards, such as hardness and toughness, will change. In low-temperature environments, materials tend to become brittle and their flexibility is greatly reduced, making the circuit board more prone to cracking or even breaking during bending. In high-temperature environments, materials may soften, which will reduce the shape stability of the circuit board and make it easy to cause excessive deformation during bending, making it difficult to maintain the predetermined bending angle.

[0004] To address the aforementioned issues, this application proposes an FPC circuit board quality inspection device. Utility Model Content

[0026] Specifically, a connecting plate 18 is fixedly connected to the left side of the protective door 8. The left side of the connecting plate 18 is fixedly connected to the right side of the controller 4 and the numerical display board 5. In this embodiment, the controller 4 and the numerical display board 5 can be fixedly used through the connecting plate 18. At the same time, the numerical display board 5 is a display tool that displays certain electronic documents on a screen through a specific transmission device and then reflects them to the human eye.

[0027] Specifically, two sets of support columns 2 are fixedly connected to the bottom surface of the box 1. Each support column 2 has a support ring 6 fixedly connected to its bottom end. In this embodiment, the support column 2 can fix the support ring 6 to the box 1, and the support ring 6 can be used to make the box 1 stable.

[0028] Specifically, each heating element 7 has a connecting bracket 17 fixedly connected to its outer surface. The side of each connecting bracket 17 that is far apart from each other is fixedly connected to the inner wall of the housing 1. In this embodiment, the heating element 7 can be fixed to the housing 1 through the connecting bracket 17. At the same time, the heating element 7 is made by inserting a heating wire into a seamless metal tube, filling the gap with magnesium oxide powder with good thermal conductivity and insulation, and then shrinking the tube. It is then processed into various shapes required by the user.

[0029] Specifically, two sets of fixing blocks 12 are fixedly connected to the outer surface of the refrigeration tube rack 11. The upper surface of each set of fixing blocks 12 is fixedly connected to the inner top wall of the box 1. In this embodiment, the refrigeration tube rack 11 can be fixed to the box 1 through the fixing blocks 12, thereby making the refrigeration tube rack 11 sturdy.

[0030] Specifically, a support plate 14 is fixedly connected to the bottom surface of the refrigeration unit 13. The left side of the support plate 14 is fixedly connected to the right side of the housing 1. In this embodiment, the refrigeration unit 13 can be fixed to the housing 1 through the support plate 14.

[0032] The working principle and usage process of this utility model are as follows: First, connect the numerical display board 5, heating element 7, cooling unit 13, bending inspection machine 9, and controller 4 to the power supply. Connect the numerical display board 5, heating element 7, and cooling unit 13 to the controller 4 via wires. When bending inspection of the FPC circuit board quality is required, move the housing 1 to a suitable position. Simultaneously, support the housing 1 using the support column 2 and support ring 6. Open the protective door 8 using the handle 3, and fix the FPC circuit board onto the bending inspection machine 9. Turn on the bending inspection machine 9 to perform bending inspection on the FPC circuit board. When the inspection requires a temperature increase, turn on the heating element 7 via the controller 4. Simultaneously, the temperature inside the housing 1 will rise due to the activation of the heating element 7. The temperature sensor 15 senses the temperature inside the chamber 1 and transmits the value to the display panel 5 via wires. When the temperature rises to a suitable range, the controller 4 turns off the heating element 7. When the temperature needs to be lowered, the controller 4 turns on the refrigeration unit 13 again via wires. The refrigeration unit 13, in conjunction with the connecting pipe 10, cools the refrigeration tube rack 11, thereby lowering the temperature inside the chamber 1. When the temperature sensor 15 and the display panel 5 reach a suitable temperature range, the controller 4 turns off the refrigeration unit 13 again. This allows the bending inspection machine 9 to control the temperature during FPC circuit board quality inspection, further improving the quality inspection effect of FPC circuit boards.
