[0003] Existing FCT testing equipment cannot automatically clean dust adhering to the product surface during use. After repeated use, dust easily accumulates on the probe surface, and when in contact with the product during power-on testing, the dust on both sides can affect the power-on effect, thereby reducing the accuracy of the test and diminishing the effectiveness of the FCT testing equipment.

[0004] To address this issue, we propose an FCT testing device that can clean the product. Utility Model Content

[0005] The purpose of this application is to solve the problem that existing technologies cannot automatically clean dust, and to propose an FCT testing device that can clean products.

A threaded rod is rotatably connected to the interior of the support frame. A servo motor is fixedly connected to the right end of the threaded rod. A moving block is threadedly connected to the outer surface of the threaded rod. The moving block is slidably connected to the interior of the support frame. A cleaning brush is fixedly connected to the bottom surface of the moving block. A multi-port suction pipe is fixedly connected to the inner wall of the moving block. An auxiliary slot is opened inside the machine base. A filter box is slidably connected inside the auxiliary slot. A negative pressure pump is fixedly connected to the right side of the machine base. The air inlet of the negative pressure pump extends into the interior of the auxiliary slot. A flexible hose is fixedly connected to the end of the multi-port suction pipe away from the servo motor. The bottom end of the flexible hose passes through the machine base and extends into the interior of the auxiliary slot.

[0008] Preferably, an electric telescopic rod is fixedly connected to the inner wall of the support frame, a probe is fixedly connected to the telescopic end of the electric telescopic rod, and two sets of barcode scanners are fixedly connected to the inner wall of the probe.

[0009] Preferably, a data acquisition card and a programmable power supply are fixedly connected to the left side of the machine tool, and both the data acquisition card and the programmable power supply are connected to the industrial control computer via wires.

[0010] Preferably, a communication module and a programmer are fixedly connected to the front of the support frame, and both the communication module and the programmer are electrically connected to the industrial control computer via wires.

[0011] Preferably, an auxiliary bearing is fitted onto the outer surface of the threaded rod, and the auxiliary bearing is embedded inside the support frame.

[0014] Preferably, a second handle is fixedly connected to the left side of the filter box, and the outer surface of the second handle is covered with an anti-slip sleeve.

[0015] In summary, the technical effects and advantages of this application are as follows:

[0016] By setting up an organic platform, support frame, industrial control computer, fixture, threaded rod, servo motor, moving block, cleaning brush, multi-port suction pipe, hose, auxiliary tank, filter box, and negative pressure pump, the industrial control computer can simultaneously control the servo motor and negative pressure pump to start before testing. The servo motor drives the threaded rod to alternate forward and reverse rotation, and the moving block drives the cleaning brush and multi-port suction pipe to move repeatedly. The negative pressure pump draws air from the auxiliary tank to create negative pressure, and the hose, in conjunction with the multi-port suction pipe, draws air from below. The cleaning brush then cleans the dust adhering to the product surface, and the dust is simultaneously sucked into the filter box through the multi-port suction pipe. The dust in the air is then left in the filter box, and finally, the excess air is discharged. This solves the problem that existing FCT testing equipment cannot automatically clean the dust adhering to the product surface during use, and that dust easily accumulates on the probe surface after repeated use, which can affect the electrical conduction effect when in contact with the product during electrical testing. This effectively improves the accuracy of the test and enhances the performance of the FCT testing equipment. Attached Figure Description

[0025] A cleaning brush 9 is fixedly connected to the bottom surface of the movable block 7, and a multi-port suction pipe 10 is fixedly connected to the inner wall of the movable block 7. A communication module 20 and a programmer 21 are fixedly connected to the front of the support frame 2.

The programmer 21 is used to burn the BOOT and PCBA software, and the communication module 20 is used to transmit data, which increases the convenience of using the device.

[0026] The machine tool 1 has an auxiliary groove 12 inside, and a filter box 13 is slidably connected inside the auxiliary groove 12. An auxiliary bearing 22 is sleeved on the outer surface of the threaded rod 5 and is embedded in the support frame 2. The auxiliary bearing 22 can reduce the friction generated by the threaded rod 5 when rotating, improve the sensitivity of the threaded rod 5 when rotating, and also reduce the wear rate of the threaded rod 5 and increase the durability of the threaded rod 5.

[0027] A negative pressure pump 14 is fixedly connected to the right side of the machine base 1. The air inlet of the negative pressure pump 14 extends into the interior of the auxiliary slot 12. A storage box 23 is slidably connected inside the machine base 1. A first handle 24 is fixedly connected to the left side of the storage box 23. The storage box 23 can store commonly used tools, increasing the convenience of using the device. The first handle 24 provides a good force-bearing position for the storage box 23, increasing the convenience of pulling the storage box 23.

[0028] Two reinforcing rings 25 are fixedly connected to the outer surface of the first handle 24. The right end of each reinforcing ring 25 is fixedly connected to the left side of the storage box 23. The reinforcing rings 25 can increase the fixed connection area between the first handle 24 and the storage box 23, making the connection between the two more secure, preventing the connection from loosening after long-term use, and increasing the durability of the device.

[0029] The end of the multi-port suction pipe 10 away from the servo motor 6 is fixedly connected to a hose 11. The bottom end of the hose 11 passes through the machine base 1 and extends into the interior of the auxiliary slot 12. A second handle 26 is fixedly connected to the left side of the filter box 13. The outer surface of the second handle 26 is covered with an anti-slip sleeve 27. The second handle 26 can provide a good force point for the filter box 13, increasing the ease of pulling the filter box 13. The anti-slip sleeve 27 can improve the firmness when gripping the second handle 26.

[0030] The working principle of this utility model is as follows: In use, first connect the industrial control computer 3, servo motor 6, negative pressure pump 14, electric telescopic rod 15, probe 16, barcode scanner 17, data acquisition card 18, programmable power supply 19, communication module 20, and programmer 21 to the power supply. When the device is needed, place the PCBA product to be tested in the fixture 4, obtain the product's QR code through the barcode scanner 17, and query the production work order information for subsequent retrieval. When the barcode scanner 17 detects a product in the fixture 4, it will... The wire sends an electrical signal to the industrial control computer 3, which then simultaneously starts the servo motor 6 and the negative pressure pump 14. The servo motor 6 drives the threaded rod 5 to rotate in both forward and reverse directions alternately. The auxiliary bearing 22 increases the sensitivity of the threaded rod 5 during rotation, which in turn causes the moving block 7 to drive the cleaning brush 9 and the multi-port suction pipe 10 to move repeatedly above the fixture 4. When the cleaning brush 9 moves, it can sweep away the dust adhering to the product surface. At the same time, the negative pressure pump 14 will extract the air in the auxiliary tank 12 and put it in a negative pressure state, thereby softening... The tube 11 provides suction to the multi-port suction tube 10, causing the multi-port suction tube 10 to continuously draw air from below, thereby drawing the dust swept by the cleaning brush 9 into the filter box 13. The filter box 13 then filters the dust in the air and discharges excess air through the negative pressure pump 14, thus achieving automatic dust cleaning of the PCBAC product surface and preventing dust from affecting the power-on effect and stability during testing. After cleaning is completed, the industrial control computer 3 sends an electrical signal to the electric telescopic rod 15, which in turn drives the probe 16 to descend and make the probe 16 contact the PCBA product. At the same time, the communication module 20 sends instructions to the target to execute the corresponding test program. The data acquisition card 18 collects signals from each test point of the PCBA, and the industrial control computer 3 software identifies the features to determine whether they are qualified. The indicator lights show whether the products at each station are qualified. When it is necessary to clean the dust in the filter box 13, the second handle 26 is pulled to move the filter box 13 out, effectively increasing the use effect of the FCT testing equipment.
