[0002] A circuit board can be called a printed circuit board or a printed circuit board, also known as a flexible circuit board. A flexible circuit board is a highly reliable and extremely flexible printed circuit board made of polyimide or polyester film as a substrate. Aging test equipment is a device that detects the performance of a circuit board by creating a high-temperature environment. It is commonly found in the field of circuit board production and manufacturing.

[0003] In the patent application with the authorization publication number CN219891366U and the authorization publication date 2023-10-24, and the name of "A Circuit Board High-Temperature Aging Test Box", the circuit board bodies that need to be subjected to high-temperature aging tests are respectively plugged into the circuit board clamps provided on the top of the concave bottom plate, and by rotating four fastening nuts, the four fastening nuts move downward to squeeze the top plate, and the top plate moves downward, so that the circuit board clamp provided at the bottom of the top plate clamps the top of the circuit board body, and the concave bottom plate and the top plate clamp the circuit board body;

[0004] In actual use of the above device, by rotating the four fastening nuts, all circuit board bodies between the top plate and the concave bottom plate are clamped. However, this method is cumbersome to operate and inconvenient to perform synchronous testing on circuit boards of different sizes.

[0005] So we proposed a circuit board aging test equipment to solve the above problems. Utility Model Content

[0010] The circuit board limiting mechanism includes a bottom support plate slidably mounted on the upper part of the slide rail, and side support plates are fixedly installed on the left and right sides of the upper end of the bottom support plate. An upper support plate is slidably mounted up and down between the two side support plates, and an adjustment mechanism is installed between the upper support plate and the side support plates;

[0013] Through the above technical solution, hot air can be evenly dispersed onto the circuit board.

[0014] Furthermore, the adjustment mechanism includes a guide rod and a rotating rod arranged in parallel. The guide rod is fixedly installed on the side support plate, and the rotating rod is installed on the side support plate through a bearing. A slider is sleeved on the outer sides of the guide rod and the rotating rod, and the slider is respectively slidably connected and threadedly connected to the guide rod and the rotating rod.

[0015] Through the above technical solution, after rotating the rotating rod, the slider can be driven to slide left and right.

[0016] Furthermore, two sliders are symmetrically arranged about the center of the upper support plate on the left and right, and the thread directions of the left and right sliders are opposite. The slider and the upper support plate are connected to a connecting plate through a movable shaft.

[0017] Through the above technical solution, after the slider slides, the upper support plate is driven to slide up and down under the action of the connecting plate.

[0022] 3. Beneficial effects:

[0023] Compared with the prior art, the circuit board aging test equipment of the utility model adopts the technical solution provided by the utility model.

[0024] After the staff opens the cover door, they pull the circuit board limiting mechanism from the slide rail to the outside of the test box, and then insert the circuit boards to be tested into the clamping table one by one. The limiting plate is pressed and fitted against the side of the circuit board with the cooperation of the guide column and the pressure spring to achieve the positioning effect. Then the rotating rod is rotated, and the rotating rod uses the threaded connection between the two sliders and the limiting effect of the guide rod to drive the two sliders to move back to each other. The upper support plate uses the connecting plate connected to the sliders to drive the upper clamping table to move downward, and the circuit board located between the upper and lower clamping tables can be quickly fixed, and the operation is more convenient. When the same batch needs to test circuit boards of different sizes and models, the threaded rod is rotated.
