Technical Field
[0001] This utility model relates to the field of FCT testing technology, and in particular to an FCT testing device. Background Technology
[0002] FCT testing, or functional testing, is a comprehensive process for testing and verifying the functionality of electronic devices or systems. By simulating real-world usage scenarios, it verifies whether each function of the product is complete and accurate, and whether different functions can work together, thereby identifying potential functional defects and ensuring product quality and reliability.
[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Existing CFT testing devices generally include a testing device body, a testing mechanism, a fixing mechanism, and other structures. Most existing fixing mechanisms can only fix PCB boards of a certain model and cannot fix PCB boards of different thicknesses. At the same time, after testing one side of the PCB board, the existing testing mechanism requires manually flipping the PCB board to test the other side, which increases the workload of workers.
[0004] Therefore, those skilled in the art have provided an FCT testing device to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an FCT testing device. This device can fix PCBs of different thicknesses using a fixing mechanism and can quickly test both sides of the PCB using an adjustment mechanism.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an FCT testing device, comprising a fixing mechanism, an adjusting mechanism, and a housing. The fixing mechanism includes a protrusion, a top frame, a bottom frame, and a rotating shaft. A locking block is fixedly connected to the center of the top frame and the bottom frame near the protrusion. The top and bottom of the protrusion are slidably connected to the two locking blocks closest to each other. Multiple springs are fixedly arranged on both sides of the bottom of the top frame, and the bottoms of the multiple springs are fixedly connected to both sides of the top of the bottom frame. A probe plate is fixedly arranged at the bottom of the upper half of the housing.
[0007] The adjustment mechanism includes a screw, a slider is threadedly connected to the outer wall of the screw, a second motor is fixedly connected to the inner wall of the slider near the top frame, and the output end of the second motor is fixedly connected to the center of the bottom frame away from the protrusion.
[0008] Furthermore, a limiting frame is fixedly connected to the inner wall of the housing on the side away from the two locking blocks and near the top, and the bottom of the screw is rotatably embedded in the inner wall of the bottom of the limiting frame.
[0009] Furthermore, a No. 1 motor is fixedly installed on the inner wall of the top of the limiting frame, and the output end of the No. 1 motor is fixedly connected to the top of the screw.
[0010] Furthermore, a limiting sleeve is fixedly provided on the top of the bottom card block of the two card blocks, and the two limiting sleeves are connected to the rotating shaft through bearings.
[0011] Furthermore, the middle of the outer wall of the rotating shaft is fixedly connected to the center of the inner wall of the protrusion, and a rotating wheel is fixedly connected to the end of the rotating shaft away from the screw.
[0012] Furthermore, a fixing rod is fixedly installed at the top center of the bottom frame at the end away from the card blocks, and the outer wall of the fixing rod is slidably connected to the inner wall of the top frame at the end away from the two card blocks.
[0013] Furthermore, multiple wheels are fixedly installed at the bottom of the housing, and an indicator light is fixedly installed at the top of the housing.
[0014] This utility model has the following beneficial effects:
[0015] 1. The FCT testing device proposed in this utility model involves rotating a rotating wheel, which drives the rotating shaft and protrusion to rotate. The protrusion separates two locking blocks, and the two locking blocks cause the top frame and bottom frame to move in the up and down directions. Then, the PCB board is placed in the middle of the bottom frame and top frame. After the rotating wheel is rotated and the top frame and bottom frame lose the resistance of the protrusion, they are reset under the action of multiple springs. This device can fix PCB boards of different thicknesses.
[0016] 2. The FCT testing device proposed in this utility model involves a first motor that rotates a screw, which in turn causes a slider to move downwards via a second motor, along with the bottom frame and PCB board, until they contact the probe plate and the bottom of the PCB board is detected. Then, under the action of the first motor, the PCB board and other structures are reset, and the second motor starts working, causing the bottom frame and top frame of the PCB board to rotate 180 degrees. Finally, under the action of the screw of the first motor, the PCB board and other structures move downwards, causing the top of the PCB board to contact the probe plate. This allows for rapid testing of both sides of the PCB board without the need for manual flipping. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1-5 This utility model provides an embodiment of an FCT testing device, comprising a fixing mechanism 1, an adjusting mechanism 2, and a housing 3. The fixing mechanism 1 includes a protrusion 101, a top frame 105, a bottom frame 103, and a rotating shaft 108. A locking block 107 is fixedly connected to the center of the top frame 105 and the bottom frame 103 near the protrusion 101. The top and bottom of the protrusion 101 are slidably connected to the two locking blocks 107 on their closest sides. Multiple springs 104 are fixedly installed on both sides of the bottom of the top frame 105, and the bottoms of the multiple springs 104 are fixedly connected to the top sides of the bottom frame 103. A probe plate is fixedly installed on the bottom of the upper half of the housing 3. The adjusting mechanism 2 includes a screw 203, with a slider 204 threadedly connected to the outer wall of the screw 203. A second motor 205 is fixedly connected to the inner wall of the slider 204 near the top frame 105, and the output end of the second motor 205 is fixedly connected to the center of the bottom frame 103 away from the protrusion 101.
[0026] Specifically, the rotation of the rotating wheel 102 causes the rotating shaft 108 and the protrusion 101 to rotate. The protrusion 101 separates the two locking blocks 107, the top frame 105, and the bottom frame 103. At the same time, the top frame 105 and the bottom frame 103 drive multiple springs 104 to separate to both sides. Then, the PCB board is placed between the bottom frame 103 and the top frame 105. The rotating wheel 102 is then slowly rotated to reset the protrusion 101. Finally, the multiple springs 104 slowly reset, and the top frame 105 and the bottom frame 103 fix the PCB board. The first motor 202 drives the screw 203 to rotate, and the screw 203 causes the slider 204 to drive the second motor 205, the bottom frame 103, and the PCB board. The PCB board and other structures move downwards and contact the probe plate to inspect the PCB board surface. Motor 1 202 flips, causing screw 203 to flip as well. Screw 203 causes slider 204, motor 205, and the PCB board to move upwards. When they reach the middle of screw 203, motor 205 starts, causing the bottom frame 103 and top frame 105 of the PCB board to rotate 180 degrees. Then, motor 202 starts, causing screw 203 to rotate. Screw 203 causes motor 205 to move the PCB board and other structures downwards, so that the top of the PCB board contacts the probe plate. This allows for rapid inspection of both sides of the PCB board without the need for workers to switch back and forth.
[0027] Reference Figures 1-5 A limiting frame 201 is fixedly connected to the inner wall of the housing 3 near the top on the side away from the two locking blocks 107. The bottom of the screw 203 is embedded and rotated on the inner wall of the bottom of the limiting frame 201. A first motor 202 is fixedly installed on the inner wall of the top of the limiting frame 201. The output end of the first motor 202 is fixedly connected to the top of the screw 203. A limiting sleeve 109 is fixedly installed on the top of the bottom locking block 107. The two limiting sleeves 109 are connected to the rotating shaft 108 through bearings. The middle of the outer wall of the rotating shaft 108 is fixedly connected to the center of the inner wall of the protrusion 101. A rotating wheel 102 is fixedly connected to the end of the rotating shaft 108 away from the screw 203. A fixing rod 106 is fixedly installed at the top center of the end of the bottom frame 103 away from the locking blocks 107. The outer wall of the fixing rod 106 is slidably connected to the inner wall of the top frame 105 at the center of the end away from the two locking blocks 107. Multiple wheels are fixedly installed at the bottom of the housing 3. An indicator light is fixedly installed at the top of the housing 3.
[0028] Specifically, the limiting frame 201 provides support for the screw 203, the first motor 202 provides power to the screw 203, the slider 204 moves along the inner wall of the limiting frame 201, and is restricted by the limiting frame 201 to not rotate, only move. The two limiting sleeves 109 provide support for the rotating shaft 108. At the same time, the rotating shaft 108 and the two limiting sleeves 109 are connected by bearings, so that the rotating shaft 108 can only rotate and cannot move. The rotating wheel 102 makes the rotation of the rotating shaft 108 more convenient. The height of the protrusion 101 is about three centimeters and the width is 0.8 millimeters, which means that the overall structure can fix PCB boards with a thickness of 0.8mm to 3cm. The fixing rod 106 can make the top frame 105 and the bottom frame 103 always aligned front, back, left and right, without offset. The multiple wheels at the bottom of the housing 3 make the whole structure easy to move. The indicator lights can be used to understand the overall working status.
[0029] Working principle: Rotating the wheel 102 drives the rotating shaft 108 and the protrusion 101 to rotate. When the protrusion 101 pushes open the two latches 107, the two latches 107 drive the top frame 105 and the bottom frame 103 to move in the up and down directions respectively. At the same time, multiple springs 104 are pulled in the up and down directions. At this time, the PCB board is placed between the bottom frame 103 and the top frame 105. Then, the wheel 102 is slowly rotated to make the protrusion 101 rotate slowly, so that the multiple springs 104 slowly return to their original position, preventing the top frame 105 and the bottom frame 103 from quickly returning to their original position and damaging the PCB board.
[0030] Next, start motor 202. The output of motor 202 rotates, causing screw 203 to rotate. Screw 203 causes slider 204 to move motor 205 downward. Motor 205 moves the bottom frame 103, top frame 105, PCB board, and other structures downward to contact the probe plate for PCB board inspection. Then, motor 202 flips, causing screw 203 to flip. Screw 203 moves slider 204 and motor 205 upward. Motor 205 moves the PCB board and other structures upward. When the PCB board reaches the middle position of screw 203, the output of motor 205 rotates, causing the bottom frame 103, top frame 105, and other structures of the PCB board to rotate 180 degrees. Then, motor 202 drives screw 203 to rotate, causing motor 205 to move the PCB board and other structures downward to contact the probe plate, allowing for rapid inspection of both sides of the PCB board.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
