Through automated testing and precise data analysis, it contributes to quality control during the electronic product manufacturing process.

[0003] Functional testing equipment provides a simulated operating environment for PCBA boards, applies stimuli, and measures the output response to verify whether their functions meet design requirements. This is a crucial step in ensuring normal product functionality. By conducting comprehensive functional testing on PCBA boards, functional testing equipment can identify and resolve potential problems and defects early, ensuring product quality and reliability. This helps reduce defect rates and after-sales maintenance costs. Functional testing equipment typically has automated testing capabilities, enabling rapid and accurate testing of large numbers of circuit boards, thereby significantly improving production efficiency and reducing production costs. In summary, PCBA board functional testing equipment plays a vital role in the electronic product manufacturing process and is one of the key pieces of equipment for ensuring product quality and improving production efficiency. The problem with the above technology is that during the functional testing of PCBA boards using a testing machine, testing requires the cooperation of a bottom mold and a top mold. However, after testing, the PCBA board, stuck inside the bottom mold, is prone to jamming due to the pressure of the top mold, making it difficult for users to quickly remove the PCBA board stuck inside the bottom mold.

[0005] This utility model is implemented as follows: a PCBA board functional testing device includes a testing machine, a bottom mold, and an upper mold. The bottom mold is located in the inner cavity of the testing machine and is fixedly connected to the inner wall of the testing machine. The upper mold is located at the output end of the top of the testing machine and is fixedly connected to the output end of the testing machine. The bottom of the upper mold is horizontally aligned with the top of the bottom mold.

By setting up the ejector mechanism, the connecting plate can simultaneously drive multiple ejector rods to move, thereby enabling the simultaneous ejection of multiple PCBA boards from the cavity of the bottom mold and preventing PCBA boards from getting stuck within the cavity of the bottom mold.

[0007] To improve the stability of the top material feeding mechanism, preferably, the connecting mechanism includes a vertical plate, an L-shaped plate, and a cylindrical rod. The surface of the vertical plate is slidably connected to the inner wall of the testing machine. The front and rear sides of the vertical plate are both in contact with the surface of the arc plate. The side of the L-shaped plate closest to the vertical plate is fixedly connected to the surface of the vertical plate. The cylindrical rod is located at the bottom of the L-shaped plate and is fixedly connected to the bottom of the L-shaped plate. By setting the connecting mechanism, the vertical plate can stably drive the connecting plate to move horizontally through mutual cooperation with the connecting plate, avoiding the shaking of the connecting plate during movement.

[0008] To improve the ease of use of the top-loading mechanism, preferably, the lifting mechanism includes an electric telescopic rod, a horizontal plate, and two assembly rods. The electric telescopic rod is located in the inner cavity of the testing machine and is fixedly connected to the inner wall of the testing machine.

The two assembly rods are located on the left and right sides of the horizontal plate and are fixedly connected to the left and right sides of the horizontal plate, respectively. The top of the assembly rod is fixedly connected to the bottom of the cylindrical rod by bolts. By setting up the lifting mechanism, the electric telescopic rod can quickly drive the connecting mechanism and the top-loading mechanism through the cooperation of the horizontal plate and the assembly rods.

[0009] To improve the stability of the connecting mechanism, preferably, limit rods are fixedly connected to both the left and right sides of the inner cavity of the testing machine. A spring is sleeved on the surface of the limit rod, and a sliding plate is fixedly connected to the bottom of the spring. The inner cavity of the sliding plate is movably connected to the surface of the limit rod, and the side of the sliding plate closest to the vertical plate is fixedly connected to the surface of the vertical plate. By setting the limit rod, spring, and sliding plate, the limit rod can assist the vertical plate in moving through the cooperation of the sliding plate and the spring. Furthermore, the force exerted on the spring by the sliding plate can increase the resistance of the vertical plate during movement, avoiding excessive output force from the ejection mechanism.

[0011] To improve the performance of the ejector mechanism, preferably, the ejector rod is made of soft rubber, and the top surface of the ejector rod is horizontally aligned with the groove in the inner cavity of the bottom mold. By setting the ejector rod and making it of soft rubber, the PCBA board can be further protected and damage to the PCBA board can be avoided during the ejection process.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, through the setup of a testing machine, a bottom mold, an upper mold, an ejector mechanism, a connecting mechanism, and a lifting mechanism, places the PCBA board within the inner cavity of the bottom mold and starts the testing machine to perform functional testing. After the test is completed, the electric telescopic rod is activated. The electric telescopic rod, through its output end, drives the horizontal plate and assembly rod to rise. During the rising process, the assembly rod, through the cooperation of the cylindrical rod and the L-shaped plate, drives the vertical plate to move accordingly. During the movement of the vertical plate, the sliding plate compresses the spring, thereby increasing the resistance to the movement of the vertical plate by the pressure of the spring. Furthermore, during the movement of the vertical plate... The connecting plate moves through the interaction of the arc plate and the positioning pin. During the movement, the connecting plate ejects multiple PCBA boards from the inner cavity of the bottom mold via the ejector rod, thus achieving the effect of quickly removing PCBA boards. This solves the problem that when using a testing machine to perform functional testing on PCBA boards, the bottom mold and top mold need to work together for testing. However, after the test is completed, the PCBA boards stuck inside the bottom mold are easily jammed due to the pressure of the top mold, making it inconvenient for users to quickly remove the PCBA boards stuck inside the bottom mold.

[0023] The working principle of this utility model:

[0024] In use, the PCBA board is placed in the inner cavity of the bottom mold 2, and the testing machine 1 is started to perform a functional test. After the test is completed, the electric telescopic rod 601 is started. The electric telescopic rod 601 will drive the horizontal plate 602 and the assembly rod 603 to rise through its output end. During the rising process, the assembly rod 603 will drive the vertical plate 501 to move along with it through the cooperation of the cylindrical rod 503 and the L-shaped plate 502. During the movement of the vertical plate 501, the sliding plate 9 will compress the spring 8, thereby increasing the resistance of the vertical plate 501's movement by increasing the pressure on the spring 8. During the process, the arc plate 403 and the positioning pin 10 work together to move the connecting plate 402. As the connecting plate 402 moves, it can push out multiple PCBA boards in the inner cavity of the bottom mold 2 through the push rod 401, thereby achieving the effect of quickly removing the PCBA boards and avoiding the situation where the PCBA boards are stuck in the inner cavity of the bottom mold 2 and cannot be removed. After the PCBA boards are removed, the electric telescopic rod 601 is turned off, and the spring force of the spring 8 rebounds. Through the cooperation of the limit rod 7 and the sliding plate 9, the vertical plate 501 is quickly reset, and the connecting plate 402 and the push rod 401 return to their original positions.

[0025] The specific model specifications of the test machine 1, bottom mold 2, top mold and electric telescopic rod 601 proposed in this application need to be selected and determined according to the actual specifications of the device. The specific selection calculation method, circuit connection method and control method all adopt the existing technology in this field, so they will not be described in detail.
