The microprocessor processes signal data through algorithms, the digital signal processor executes complex PID control and vector control, the memory stores data, and the input / output interfaces provide communication interfaces with external devices. The inverter control board is a precision component and requires quality inspection during the production process.

[0003] Quality inspection of inverter control boards requires the use of a quality inspection device, which includes an optical inspection device. After the inverter control board is conveyed by the optical inspection device, the optical inspection device performs optical inspection on one side of the inverter control board to detect solder joints, the position of electronic components, and PCB board damage. Then, the other side of the inverter control board needs to be manually flipped by the operator, which will affect the inspection efficiency of the inverter control board.

[0004] Therefore, how to provide a quality inspection device for the production of frequency converter control boards is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a quality inspection device for the production of frequency converter control boards. This invention solves the problem in the prior art where optical inspection devices require manual flipping of the frequency converter control board after inspecting one side, which affects the inspection efficiency of the frequency converter control board.

[0006] A quality inspection device for the production of frequency converter control boards according to an embodiment of the present utility model includes a control board and a conveyor belt body. The control board is movable on the conveyor belt body. A side plate is provided on one side of the conveyor belt body, a support frame is provided on the side plate, a controller is provided on one side of the support frame, and an optical inspection device located directly above the control board is provided at the other end of the support frame.

[0007] The support frame is provided with a longitudinal movable component, the longitudinal movable component is provided with a rotating component, the rotating component is provided with a clamping component, and one end of the clamping component is clamped to the side of the control panel near the side plate.

[0008] The height of the side plate is lower than the height of the conveyor belt body. A support pulley is provided on the top of the side plate corresponding to the position of the control plate. The control plate slides on the support pulley, and the clamping assembly is located between the support pulleys.

[0009] The longitudinal movable component includes a longitudinal adjusting motor and a longitudinal adjusting rod. A longitudinal groove parallel to the support frame is longitudinally opened on the side of the support frame near the control panel. The longitudinal adjusting rod is rotatably connected in the groove through a bearing. An adjusting block is movably sleeved on the surface of the longitudinal adjusting rod inside the groove. The adjusting block moves inside the groove. The bottom end of the longitudinal adjusting rod passes through the support frame and extends to the bottom of the support frame. The longitudinal adjusting motor is fixed at the bottom of the support frame corresponding to the position of the longitudinal adjusting rod. A first transmission gear is provided on the surface of the longitudinal adjusting rod below the support frame. A first power gear is provided on the output shaft of the longitudinal adjusting motor. The first power gear and the first transmission gear mesh with each other.

[0010] The rotating assembly includes a mounting plate, a fixed shaft, and a rotating cylinder. The mounting plate is installed on the top of the adjusting block at a position offset from the longitudinal adjusting rod. A rotary motor is installed on the mounting plate. A second power gear is fixed on the output shaft of the rotary motor. A second transmission gear meshes with the second power gear. The fixed shaft is fixed on one side of the adjusting block. The rotating cylinder is rotatably sleeved on the fixed shaft through a bearing. The second power gear is fixedly sleeved on the surface of the rotating cylinder.

[0011] The output shaft of the rotary motor is rotatably connected to the mounting plate.

[0012] The clamping assembly includes a clamping frame and a clamping motor. The clamping frame is located at the end of the rotating cylinder away from the fixed axis, and the clamping motor is located on one side of the clamping frame. A double set of threaded rods is rotatably connected inside the clamping frame. One end of the double set of threaded rods is fixed to the output shaft of the clamping end machine. Two clamping plates are threadedly fitted onto the surfaces of the double set of threaded rods at positions corresponding to two different sets of threads. One end of the two clamping plates is movable inside the clamping frame, and the shape and size of the two clamping plates located inside the clamping frame match the shape and size of the inner wall of the clamping frame. The two clamping plates are located at the top and bottom of the control plate, respectively.

[0013] A protective layer is provided at the position where the opposing surfaces of the two clamping plates are in contact with the control plate.

[0014] The beneficial effects of this utility model are:

[0015] By setting up a controller, a longitudinal adjustment component, a rotating component, and a clamping component, the controller controls the clamping component to clamp onto one end of the control board. Then, the longitudinal adjustment component drives the rotating component, the clamping component, and the clamped control board to move upwards towards the optical detection device for detection on that side. After the rotating component starts, it drives the clamping component to rotate, causing the control board to flip over through the clamping component. After flipping 180 degrees, the rotation stops. Then, the optical detection device detects one side of the control board after it has been flipped. This achieves the purpose of detecting both sides of the control board by automatically flipping it over, which solves the problem in the prior art where the optical detection device needs to manually flip the control board after detecting one side, thus affecting the detection efficiency of the inverter control board. After the detection is completed, the longitudinal adjustment component, the rotating component, and the clamping component return to their original positions, and the clamping component separates from the control board. Then, when the next control board is transported to this position by the conveyor belt, the flipping operation is performed again. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

The support pulley 10 is also provided on the side plate 3. The control board 1 is supported at one end. There are gaps between the support pulleys 10, and the clamping assembly 9 is located between the support pulleys 10. This design facilitates the clamping operation of the control board 1. A support frame 4 is provided on the side plate 3 for installing the optical inspection device 6. A controller 5 is provided on one side of the support frame 4, and the optical inspection device 6 is provided at the other end of the support frame 4, which is located directly above the control board 1. The optical inspection device 6 is one of the existing quality inspection devices for the control board 1, and mainly detects whether the control board 1 is damaged, the position of components, and solder joints.

[0023] refer to Figure 2 and Figure 3The rotating assembly 8 is equipped with a clamping assembly 9. One end of the clamping assembly 9 is clamped to the side of the control plate 1 near the side plate 3. The clamping assembly 9 includes a clamping frame 23 and a clamping motor 24. The clamping frame 23 is located at the end of the rotating cylinder 19 away from the fixed shaft 18, and the clamping motor 24 is located on one side of the clamping frame 23. A double-threaded rod 25 is rotatably connected inside the clamping frame 23. The double-threaded rod 25 has two sets of opposite threads. When the double-threaded rod 25 rotates, it will drive the two clamping plates 26 to move closer to each other, thereby realizing the clamping function. One end of the double-threaded rod 25 is fixed to the output shaft of the clamping end machine. Two clamping plates are threaded onto the surface of the double-threaded rod 25 at the positions corresponding to the two sets of different threads. 26. One end of the two clamping plates 26 is movable inside the clamping frame 23, and the shape and size of the two clamping plates 26 inside the clamping frame 23 match the shape and size of the inner wall of the clamping frame 23. The two clamping plates 26 are located at the top and bottom of the control plate 1, respectively. A protective layer 27 is provided at the position where the opposite surfaces of the two clamping plates 26 are in contact with the control plate 1 to protect the surface of the control plate 1 at the clamping position. During operation, the conveyor belt body 2 moves the control plate 1 between the two clamping plates 26, and then the controller 5 starts the clamping motor 24, which drives the double threaded rods 25 to rotate. The rotation of the double threaded rods 25 causes the two clamping plates 26 to move closer to each other and clamp onto the control plate 1.

[0024] refer to Figure 3The support frame 4 is equipped with a longitudinal movable assembly 7, which includes a longitudinal adjusting motor 11 and a longitudinal adjusting rod 12. A longitudinal groove 13 parallel to the support frame 4 is longitudinally formed on the side of the support frame 4 near the control panel 1. The longitudinal adjusting rod 12 is rotatably connected to the groove 13 via a bearing. An adjusting block 14 is movably fitted onto the surface of the longitudinal adjusting rod 12 inside the groove 13, allowing it to move up and down within the groove 13. The adjusting block 14 moves within the groove 13. The bottom end of the longitudinal adjusting rod 12 passes through the support frame 4 and extends to the bottom of the support frame 4. The longitudinal adjusting motor 11 is fixed at the bottom of the support frame 4 corresponding to the position of the longitudinal adjusting rod 12. A first transmission gear 15 is provided on the surface of the longitudinal adjusting rod 12 below the support frame 4. The output shaft of the longitudinal adjusting motor 11... A first power gear 16 is provided, which meshes with the first transmission gear 15. During operation, after the two clamping plates 26 on the clamping assembly 9 clamp the control plate 1 stably, the controller 5 starts the longitudinal adjustment motor 11. The start of the longitudinal adjustment motor 11 drives the first transmission gear 15 to rotate through the first power gear 16. The rotation of the first transmission gear 15 drives the longitudinal adjustment rod 12 to rotate. The rotation of the longitudinal adjustment rod 12 will drive the adjustment block 14 to move upward along the slide groove 13. The shape of the slide groove 13 matches the shape of the adjustment block 14. The slide groove 13 guides and limits the adjustment block 14 to prevent the adjustment block 14 from rotating with the longitudinal adjustment rod 12. When the adjustment block 14 rises, the control plate 1 is raised and separated from the conveyor belt body 2 through the rotating assembly 8 and the clamping assembly 9.

[0025] refer to Figure 3The longitudinal movable component 7 is equipped with a rotating component 8, which includes a mounting plate 17, a fixed shaft 18, and a rotating cylinder 19. The mounting plate 17 is installed on the top of the adjusting block 14, offset from the longitudinal adjusting rod 12. A rotary motor 20 is mounted on the mounting plate 17, and the output shaft of the rotary motor 20 is rotatably connected to the mounting plate 17. A second power gear 21 is fixed on the output shaft of the rotary motor 20, and a second transmission gear 22 meshes with the second power gear 21. The fixed shaft 18 is fixed to one side of the adjusting block 14, and the rotating cylinder 19 is rotatably sleeved on the fixed shaft 18 through a bearing. The rotating cylinder 19 rotates on the surface of the fixed shaft 18, and the second power gear 21 is fixedly sleeved on the surface of the rotating cylinder 19. During operation, when the longitudinal movable component 7 raises the rotating component 8, the clamping component 9, and the clamped control plate 1 and inspects one side of the control plate 1... After the test is completed, the controller 5 starts the rotary motor 20, which drives the second power gear 21 to rotate. The rotation of the second power gear 21 drives the second transmission gear 22 to rotate. The rotation of the second transmission gear 22 drives the rotary cylinder 19 to rotate stably on the surface of the fixed shaft 18 through the bearing. The rotation of the rotary cylinder 19 drives the clamping assembly 9 and the clamped control plate 1 to flip. When the control plate 1 flips 180 degrees, it stops rotating. At this time, the other side of the control plate 1 faces the optical detection device 6. This flipping does not require manual operation and realizes the purpose of automatically flipping the control plate 1, which improves the detection efficiency of the control plate 1. It should be noted that after the control plate 1 is detected on both sides, the controller 5 restores the longitudinal moving assembly 7, the rotating assembly 8 and the clamping assembly 9 to their original positions, and then transports the next control plate 1 to this position and performs the flipping operation again.
