[0002] As a core component of electronic products, the quality and reliability of circuit boards directly affect the performance of the entire device. During the manufacturing process, to inspect the quality of circuit boards, it is usually necessary to sample and test the high-temperature aging rate of the boards for quality assessment. Traditional circuit board aging testing methods typically involve placing the circuit boards in a fixed location and subjecting them to long-term aging treatment in a static environment. However, this method suffers from uneven heating and incomplete aging processes, leading to inaccurate test results and an inability to comprehensively assess the stability and durability of the circuit boards. Therefore, improvements are needed to address these issues. Summary of the Invention
[0003] In view of the above situation and to overcome the existing defects, this utility model provides an easy-to-use aging test device for circuit board processing. This device can ensure that the circuit board is uniformly aged and cooled in a high-temperature environment by placing the circuit board in a fixed frame and making it rotate in the aging chamber, thus ensuring the aging effect.
[0004] This utility model provides the following technical solution: The aging test equipment for circuit board processing proposed in this solution includes an aging chamber, a cold air blower and a circuit board mounting frame. A rotating tube is rotatably provided in the middle of the two inner side walls of the aging chamber. A forward and reverse motor is installed on the outside of the aging chamber. One end of the output shaft of the forward and reverse motor is connected to the rotating tube. Multiple sets of mounting brackets are arranged around the rotating tube at intervals. The circuit board mounting frame can be detachably installed through the mounting brackets.
[0005] The circuit board mounting frame is used to install and fix circuit boards in batches. The forward and reverse motor is used to drive the rotating tube to rotate, so that the circuit board mounting frame drives the circuit board to rotate evenly in the aging chamber. The cold air fan is used to quickly cool the circuit boards after aging.
[0006] Preferred technical solution 1: The mounting bracket is slidably provided with a fixed pin at its lower end, and a pull handle is provided at one end of the fixed pin. A telescopic spring is sleeved on the fixed pin, and the two ends of the telescopic spring are respectively connected to the pull handle and the mounting bracket. The upper end of the circuit board mounting frame is symmetrically provided with hanging plates on both sides. A bushing adapted to the fixed pin is rotatably provided on the hanging plate, and one end of the fixed pin is engaged with the bushing.
[0007] Preferred technical solution 2: A rotary joint is installed at the other end of the rotary tube, and an air guide pipe is provided on the air cooler. The air guide pipe is connected to the rotary joint, and multiple sets of cooling ports are arranged around the middle of the rotary tube at intervals. The multiple sets of cooling ports correspond to the circuit board mounting frame.
[0008] Preferred technical solution 3: The circuit board mounting frame is provided with multiple sets of slots at intervals for batch mounting and fixing of circuit boards.
[0009] Preferred technical solution four: The front end of the aging chamber is equipped with a protective door, and the protective door is provided with an observation window.
[0010] Preferred technical solution five: Heaters are installed at the top and bottom ends inside the aging chamber, and a display controller for controlling the heaters is also provided on the protective door.
[0011] The beneficial effects of this utility model by adopting the above structure are as follows:
[0012] 1. The rotating tube is driven by a forward and reverse motor, which in turn makes the circuit board mounting frame rotate evenly in the aging chamber, ensuring that the circuit board is heated evenly and effectively avoiding local overheating.
[0013] 2. The mounting bracket and fixing pins allow for easy and quick disassembly and installation of the circuit board mounting frame, which improves the handling of circuit boards during batch operations and saves operation time.
[0014] 3. The cool air is delivered into the rotating tube by the set air cooler and air duct, and overflows evenly from the cooling port, which enhances airflow and accelerates the removal of heat. In conjunction with the rotation of the forward and reverse motor, it further prevents the circuit board from being damaged due to local overheating or rapid temperature changes, while ensuring the cooling speed and effect of the circuit board.

[0023] Example 1
[0024] As per the instruction manual Figure 1-4 As shown, the technical solution adopted by this utility model is as follows: The aging test equipment for circuit board processing proposed in this solution includes an aging chamber 1, a cold air blower 2, and a circuit board mounting frame 3. A protective door 17 is installed at the front end of the aging chamber 1, and an observation window 18 is provided on the protective door. A rotating tube 4 is rotatably provided in the middle of the two inner side walls of the aging chamber 1. A forward and reverse motor 5 is installed on the outside of the aging chamber 1. One end of the output shaft of the forward and reverse motor 5 is connected to the rotating tube 4. Multiple sets of mounting brackets 6 are arranged around the rotating tube 4 at intervals. The circuit board mounting frame 3 can be detachably installed through the mounting brackets 6. Heaters 16 are installed at the upper and lower ends inside the aging chamber 1. A display controller for controlling the heaters 16 is provided on the protective door 17.
[0025] The circuit board mounting frame 3 is used to install and fix circuit boards in batches. The forward and reverse motor 5 is started to drive the rotating tube 4 to rotate, so that the circuit board mounting frame 3 can drive the circuit board to rotate evenly in the aging chamber 1. The heater 16 set in the aging chamber 1 heats and ages the circuit board. The cold air fan 2 is used to quickly cool the aged circuit board.
[0026] Example 2
[0027] Based on Example 1, to further facilitate the batch handling of circuit boards, as per the appendix of the instruction manual... Figure 3 and 4 As shown, a fixed pin 7 is slidably provided at the lower end of the mounting bracket 6. A pull handle 8 is provided at one end of the fixed pin 7. A telescopic spring 9 is sleeved on the fixed pin 7. The two ends of the telescopic spring 9 are connected to the pull handle 8 and the mounting bracket 6 respectively. Hanging plates 10 are symmetrically provided on both sides of the upper end of the circuit board mounting frame 3. A bushing 11 adapted to the fixed pin 7 is rotatably provided on the hanging plate 10. One end of the fixed pin 7 is engaged with the bushing 11. Multiple sets of slots 15 for mounting and fixing circuit boards are provided at intervals inside the circuit board mounting frame 3 for batch mounting and fixing of circuit boards.
[0028] Pulling the handle moves the fixing pin 7, releasing the fixing pin 7 from the bushing 11, thus allowing the circuit board mounting frame 3 to be easily and quickly removed from the mounting bracket 6. At this time, the circuit board mounting frame 3 to be installed can be quickly installed, saving time for picking up and putting away the circuit board.
[0029] Example 3
[0030] Based on Example 1, to further facilitate rapid cooling of the aged circuit board and aging chamber, as per the instruction manual... Figure 1 and 3 As shown, a rotary joint 12 is installed at the other end of the rotary tube 4, and an air duct 13 is provided on the air cooler 2. The air duct 13 is connected to the rotary joint 12. Multiple sets of cooling ports 14 are arranged around the middle of the rotary tube 4 at intervals. The multiple sets of cooling ports 14 correspond to the circuit board mounting frame 3.
[0031] After the circuit board aging process is completed, the air cooler 2 is turned on to guide the cool air through the air duct 13 into the rotating tube 4 and out through the cooling port 14. This accelerates airflow, increases heat exchange efficiency, and quickly removes heat from the circuit board surface. At the same time, the forward and reverse motor 5 is turned on to rotate the rotating tube 4. This causes the circuit board mounting frame 3 to rotate under gravity, making the cooling process more uniform and preventing local overheating of the circuit board caused by uneven surface heat flow during natural heat dissipation. This further ensures the cooling effect of the circuit board.
