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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a multi-station rotary FCT automatic testing fixture device, including a support platform 1. The support platform 1 is used to ensure the stability of the device during operation. A motor 3 is fixedly connected inside the support platform 1. A connecting plate 5 is fixedly connected outside the motor 3. The motor 3 is used to drive the connecting plate 5 to rotate, realizing multi-station switching. A fixing mechanism 6 is set inside the connecting plate 5. The connecting plate 5 carries the PCBA circuit board to be tested and drives the circuit board to switch between different testing stations under the drive of the motor 3 to realize continuous testing. The fixing mechanism 6 is used to firmly fix the PCBA circuit board on the connecting plate 5 to prevent the circuit board from moving or shifting during the test, which would affect the accuracy of the test results. A support column 2 is fixedly connected outside the support platform 1. The support column 2 is used to provide guidance for the up and down sliding of the test board. A feeding mechanism 4 is set outside the support platform 1. The feeding mechanism 4 is used to realize the automatic gripping and feeding of PCBA circuit boards.

[0033] The fixing mechanism 6 includes a drive shaft 61, which is externally fixedly connected to the drive end of the motor 3 inside the support platform 1. The drive shaft 61 transmits the power of the motor 3 to the rotating assembly 62, driving the cylinder 63 to rotate and position. A gear ring is provided on the outside of the drive shaft 61, which meshes with a gear on the outside of the transmission column 621 to transmit the rotational motion of the drive shaft 61 to the transmission column 621. The rotating assembly 62 is provided inside the connecting plate 5. The rotating assembly 62 further converts the power of the drive shaft 61 into the rotational motion of the cylinder 63, ensuring that the cylinder 63 can accurately reach the target position. The externally fixed rotating assembly 62... Two cylinders 63 are connected. A push column 64 is fixedly connected to the drive end of the cylinder 63. The cylinder 63 is used to drive the push column 64 to move. A connecting rod 65 is fixedly connected to the opposite side of the push column 64. A fixing plate 66 is fixedly connected to the top of the connecting rod 65. The push column 64 is used to transmit the linear motion of the cylinder 63 to the connecting rod 65. The connecting rod 65 is used to connect the push column 64 and the fixing plate 66, which transmits force and pushes the fixing plate 66 to move. The fixing plate 66 is used to directly contact the PCBA circuit board. The fixing and release of the circuit board is achieved by gathering or separating. An anti-slip pad can be set on its surface to enhance the fixing effect.

[0034] A fixing plate 69 is fixedly connected to the top of cylinder 63. The fixing plate 69 provides a mounting base for the rotating disk 68 and also provides certain support and limit for cylinder 63. A fixing shaft is fixedly connected in the middle of the fixing plate 69. The rotating disk 68 is rotatably connected to the outside of the fixing shaft. The rotating disk 68 cooperates with the rotating connecting rod 67 to convert the linear motion of the pushing column 64 into a combined rotational and translational motion of the fixing plate 66, thereby achieving adaptive clamping of the circuit board. The rotating connecting rod 67 is rotatably connected to the outside of the protruding shaft of the rotating disk 68. The rotating connecting rod 67 is used to transmit the motion of the rotating disk 68 to the fixing plate 66, ensuring the coordination and synchronization of the actions of multiple fixing plates 66. The other end of the rotating connecting rod 67 is rotatably connected to the outside of the protruding shaft at the bottom of the fixing plate 66.

[0035] The rotating assembly 62 includes four transmission columns 621. The transmission columns 621 are used to distribute power to each cylinder 63 through meshing with the gear ring of the transmission shaft 61 and the transmission of the belt pulley. The external part of the transmission column 621 is rotatably connected to the inside of the connecting plate 5. Gears are provided on the external part of the transmission column 621. The external part of the transmission column 621 is meshed with the external part of the transmission shaft 61. A belt pulley is provided on the bottom side of the external part of the transmission column 621. The belt pulley is connected to the belt pulley outside the connecting column 622 through the transmission belt 623, which transmits the rotational motion of the transmission column 621 to the cylinder 63, so that the cylinder 63 rotates around the central axis of the transmission shaft 61. The bottom of the cylinder 63 is fixedly connected to the connecting column 622. The transmission belt 623 is sleeved on the external part of the connecting column 622 and the external part of the transmission column 621. The middle inner side of the connecting plate 5 is fixedly connected to the external part of the transmission shaft 61.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The feeding mechanism 4 includes a support frame 41, which is externally fixedly connected to the support platform 1. A second motor 42 is fixedly connected to the top of the support frame 41. The support frame 41 provides installation position and structural support for the second motor 42 and the transmission rotating plate 43. The drive end of the second motor 42 is fixedly connected to the transmission rotating plate 43. The second motor 42 drives the transmission rotating plate 43 to rotate, thereby realizing the rotational movement of the clamping rod 45. The external part of the transmission rotating plate 43 is fixedly connected to the clamping rod 45. The transmission rotating plate 43 rotates under the drive of the second motor 42, driving the clamping rod 45 fixed to its external part to move. The bottom of the clamping rod 45 is fixed. The device is equipped with a clamp, and the clamping rod 45 is used to mount the clamp, directly contacting and gripping the PCBA circuit board. Through its own rotation and movement, it transports the circuit board from the initial position to the designated loading position. A sliding block 46 is fixedly connected to the outside of the clamping rod 45, and a slide bar 44 is fixedly connected to the outside of the support frame 41. The clamp adopts a pneumatic or mechanical clamping method to achieve reliable gripping and release of the PCBA circuit board. The sliding block 46 is slidably connected to the outside of the slide bar 44. The sliding block 46 is used to cooperate with the slide bar 44 to provide guidance and support for the movement of the clamping rod 45, ensuring that the clamping rod 45 remains stable during rotation and movement.

[0037] A support plate 7 is fixedly connected to the top of the support column 2. The support plate 7 provides a top support point for the sliding of the test plate. A cylinder 8 is fixedly connected to the outside of the support platform 1. The cylinder 8 is used to drive the test plate to move up and down, so that the test probes on the test plate contact the test points on the PCBA circuit board. The drive end of the cylinder 8 is fixedly connected to the test plate. The test plate is used to integrate test probes, sensors and other detection components, and directly contacts the PCBA circuit board to perform electrical performance, functional parameter and other tests. The inside of the test plate is slidably connected to the outside of the support column 2.

[0038] Working principle: The transmission plate 43 is driven to rotate by the motor 42, and the clamping rod 45, which is fixedly connected to the transmission plate 43, rotates accordingly. When the clamping rod 45 rotates to the top of the PCBA circuit board to be tested, the bottom clamps descend and clamp the circuit board. Then, the sliding block 46 slides on the outer slide bar 44 of the support frame 41 to ensure the stability of the clamping rod 45 during rotation and movement. The clamping rod 45 continues to rotate while clamping the circuit board, transporting the circuit board to the designated loading position, ready to be placed on the connecting plate 5.

[0039] Motor 3 drives the drive shaft 61 to rotate, and the gear ring outside the drive shaft 61 rotates accordingly. The drive column 621, which meshes with the drive shaft 61, begins to rotate. The pulley outside the drive column 621 drives the connecting column 622 to rotate through the drive belt 623. This causes the cylinder 63 connected to the connecting column 622 to rotate around the central axis of the drive shaft 61. When the cylinder 63 rotates to the appropriate position, that is, above the PCBA circuit board to be tested, the cylinder 63 drives the push column 64 to slide in the groove inside the fixed plate 69. This drives the rotating disk 68 to rotate through the rotating connecting rod 67. The remaining rotating connecting rods 67 outside the rotating disk 68 drive the remaining fixed plates 66 to converge and slide outside the fixed plate 69 to fix the circuit board. It can also make a certain angle adaptive adjustment according to the surface condition of the PCBA circuit board.

[0040] After the PCBA circuit board is fixed, motor 3 continues to drive the transmission shaft 61 to rotate, thereby rotating the connecting plate 5 and the PCBA circuit board fixed on it to the test station. The cylinder 8 drives the test plate to slide upward along the support column 2 until the test probe on the test plate contacts the test point on the PCBA circuit board.

[0041] 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.
