Vertical plates are slidably inserted at both ends of the insertion frame. Compared with the prior art, the circuit board is clamped inside the clamping component, the upper and lower ends of the circuit board are limited, and the surfaces on both sides in the middle are hollowed out. Through soaking, brushing, rinsing and drying, in conjunction with the circulating conveyance of the conveyor belt, the cleaning of the circuit board can be completed in a process-based manner, thereby improving the cleaning efficiency of the circuit board. The two-stage cleaning makes the circuit board cleaning more thorough, and the fan dries the rotating circuit board on the moving path, saving the time spent on separate drying. In the process of realizing the present invention, the inventors found that at least the following problems exist in the prior art and have not been solved: when the circuit boards are placed for daily use, the outer walls of the stacked circuit boards are exposed to the outside, causing dust and impurities to stick to the outer walls of the circuit boards; if the circuit boards are in use, there will be impurities containing residual glue on the sides of the circuit boards; in the prior art, only the surface of the circuit boards can be cleaned, and the side edges of the circuit boards cannot be cleaned.

When the driving gear rotates, it will drive the rotating gear on the rotating rod to rotate. The other end of the rotating gear is limited by the annular gear ring, so that the rotating rod on the rotating gear rotates around the driving rod as the center. At this time, the rotating rod will drive the connecting frame to rotate around the driving rod. The plug rods arranged relatively on the connecting frame will be restricted on the supporting frame. The connecting frame rotates around the driving rod, which is convenient for the subsequent cooperation with the switching member to make the connecting frame drive the clamping cylinder to move on the driving rod to adjust the position of the clamping cylinder. S3: The rotation of the connecting frame drives the resistance rod to rotate around the driving rod. The resistance rod is driven by the pressure spring to abut against the annular groove on the bearing shell, and the resistance rod is limited by the set annular groove. Then, when the resistance rod moves to the connecting groove between the two annular grooves, the resistance rod will move to the other annular groove through the cross-set connecting groove. At this time, the upward movement of the resistance rod will drive the connecting frame to move upward, and the connecting frame and the clamping cylinder will rotate and cooperate, thereby driving the clamping cylinder to move upward on the clutch disk. At this time, the clutch sleeve set on the clamping cylinder will be clamped and transmitted with the clutch disk. At this time, when the driving rod drives the clamping cylinder to rotate, the clamping cylinder will drive the clutch disk to rotate. When the clutch disk rotates the adjusting gear, the flip device can be flipped. S4: The upper and lower ends of the circuit board are clamped by the first support block and the third support block which are arranged correspondingly. When the support frame is driven by the driving motor to rotate around the driving rod as the center of the circle, the clamped circuit board is rotated around the driving rod as the center of the circle by the two first support blocks and the third support blocks, so that the circuit board can be cleaned in a rotary manner; S5: When the resistance rod on the switching member drives the connecting frame to move upward under the restriction of the connecting groove, the two limit discs on the connecting frame will drive the clamped limit plates to move upward, and the two limit plates will pull the sliding plate upward. When the sliding plate moves upward, the sliding plate will drive the first support block to move upward. When the first support block moves upward, the two second support blocks will be relatively close to each other through the first hinged frames set on both sides of the first support block. When the first support block and the third support block relax the circuit board, the two second support blocks will clamp the left and right sides of the circuit board. S6: When the connecting frame drives the clamping cylinder to move upward on the clutch disk, the clutch sleeve on the clamping cylinder will be clamped and transmitted with the clutch disk, the driving rod drives the clamping cylinder to rotate, the clamping cylinder will drive the adjusting gear set at the bottom to rotate, the rotation of the adjusting gear will drive the rotating bevel gear to rotate, the rotating bevel gear drives the rotating rod to rotate the rotating disk, the rotating disk rotates the transmission disk through the belt, when the transmission disk drives the inner rod to rotate, since the inner rod is clamped with the moving sleeve rod on one of the second support blocks, the two second support blocks are in a state of clamping the circuit board, the first support block and the third support block are away from the circuit board, so that the second support block can rotate to flip the clamped circuit board around the inner rod as the center.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the upward movement of the resistance rod will drive the connecting frame to move upward, and the connecting frame and the clamping cylinder will rotate and cooperate with each other, thereby driving the clamping cylinder to move upward on the clutch disk. At this time, the clutch sleeve provided on the clamping cylinder will be clamped and transmitted with the clutch disk. At this time, when the driving rod drives the clamping cylinder to rotate, the clamping cylinder will drive the clutch disk to rotate. When the clutch disk causes the adjusting gear to rotate, the flipping device will be able to flip. The flipping device is arranged on the supporting frame, so as to drive the circuit board to flip and move the circuit board at all angles, so that the circuit board can be cleaned in all directions during cleaning.

[0013] In the present invention, by switching the clamping position on the outer wall of the circuit board, the side edges of the circuit board can be cleaned when the circuit board is cleaned. Since the side wall edges of the circuit board are exposed when stacked, there will generally be glue at the edges, which will affect the subsequent assembly and use of the circuit board. By cleaning the side edges of the circuit board, the circuit board can be fully cleaned at all locations, which is convenient for the subsequent assembly and use of the circuit board.

[0014] In the present invention, the clamping position of the circuit board is switched by controlling the clamping device through the switching member, and the rotation direction of the circuit board is changed at the same time, so that the circuit board can be fully and effectively cleaned and dried during the cleaning process and the subsequent drying process.

8. A method for using a computer circuit board cleaning device, using a computer circuit board cleaning device as claimed in any one of claims 1 to 7, characterized in that: The steps include: S1: The driving motor (21) drives the driving rod (22) to rotate, and the driving rod (22) drives the support frame (212) arranged at the bottom to rotate, and the clamping device (4) is slidably arranged on the support frame (212), so that the circuit board clamped by the clamping device (4) can be rotated by the driving rod (22), so that when the circuit board is in the spray cleaning area (14), it can be fully cleaned by turning the driving rod (22) as the center of the circle; S2: When the driving rod (22) rotates, the driving gear (23) can be driven to rotate. When the driving gear (23) rotates, it drives the rotating gear (211) on the rotating rod (210) to rotate. The other end of the rotating gear (211) is limited by the annular gear ring (28), so that the rotating rod (210) on the rotating gear (211) rotates with the driving rod (22) as the center. At this time, the rotating rod (210) drives the connecting frame (29) to rotate around the driving rod (22). The insertion rod (213) arranged relatively on the connecting frame (29) is restricted on the supporting frame (212). The connecting frame (29) rotates around the driving rod (22), so that it is convenient to cooperate with the switching member (3) later to enable the connecting frame (29) to drive the clamping cylinder (25) to move and adjust the position of the clamping cylinder (25) on the driving rod (22); S3: The connecting frame (29) rotates to drive the abutment rod (31) to rotate around the driving rod (22). The abutment rod (31) is abutted against the annular groove (33) on the bearing housing (12) by the pressure spring (32). The abutment rod (31) is limited by the annular groove (33). When the abutment rod (31) moves to the connecting groove (34) between the two annular grooves (33), the abutment rod (31) moves to the other annular groove (33) through the cross-connected connecting grooves (34). At this time, the abutment rod (31) moves upward. The connecting frame (29) is driven to move upward, and the connecting frame (29) and the clamping cylinder (25) are rotated and matched, thereby driving the clamping cylinder (25) to move upward on the clutch disk (24). At this time, the clutch sleeve (26) provided on the clamping cylinder (25) is engaged with the clutch disk (24) for transmission. At this time, when the driving rod (22) drives the clamping cylinder (25) to rotate, the clamping cylinder (25) drives the clutch disk (24) to rotate. When the clutch disk (24) causes the adjusting gear (27) to rotate, the flipping device (5) can be flipped. S4: The upper and lower ends of the circuit board are clamped by the first support block (45) and the third support block (411) which are arranged correspondingly. When the support frame (212) is driven by the driving motor (21) to rotate around the driving rod (22) as the center of the circle, the clamped circuit board is rotated around the driving rod (22) as the center of the circle by the two first support blocks (45) and the third support block (411), so that the circuit board can be cleaned in a rotary manner; S5: When the resistance rod (31) on the switching member (3) drives the connecting frame (29) to move upward under the restriction of the connecting groove (34), the two limiting discs (44) on the connecting frame (29) drive the clamped limiting plates (43) to move upward, and the two limiting plates (43) pull the sliding plate (41) to move upward. When the sliding plate (41) moves upward, the sliding plate (41) drives the first support block (45) to move upward. When the first support block (45) moves upward, the two second support blocks (47) are relatively close to each other through the first hinge frame (49) provided on both sides of the first support block (45). When the first support block (45) and the third support block (411) relax the circuit board, the two second support blocks (47) clamp the left and right sides of the circuit board. S6: When the connecting frame (29) drives the clamping cylinder (25) to move upward on the clutch disk (24), the clutch sleeve (26) on the clamping cylinder (25) will be clamped and transmitted with the clutch disk (24), the driving rod (22) drives the clamping cylinder (25) to rotate, and the clamping cylinder (25) drives the adjusting gear (27) arranged at the bottom to rotate. The rotation of the adjusting gear (27) drives the rotating bevel gear (52) to rotate, and the rotating bevel gear (52) drives the rotating rod (51) to rotate the rotating disk (53). The disk (53) rotates the transmission disk (55) via a belt (56). When the transmission disk (55) drives the inner rod (54) to rotate, the inner rod (54) is engaged with a movable sleeve rod (46) on one of the second support blocks (47). At this time, the two second support blocks (47) are in a state of clamping the circuit board, and the first support block (45) and the third support block (411) are away from the circuit board, so that the second support block (47) can rotate to turn the clamped circuit board around the inner rod (54) as the center.
