At the same time, the motor is controlled to drive the two protrusions to rotate and squeeze the contact plate and to control the gear three to achieve intermittent rotation. The gear three drives the round pin to rotate and in turn drives the groove wheel to rotate, so that the air outlet can fully clean different parts of the circuit board, thereby improving the uniformity and thoroughness of cleaning and ensuring that all parts of the circuit board can be effectively cleaned.

[0028] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1 As shown, a plurality of supporting legs 11 are fixedly connected to the lower surface of the frame 1;

[0031] The multiple support legs 11 evenly distributed on the lower surface of the frame 1 can bear the entire weight of the device, ensuring that the device can maintain a stable posture during operation, thereby improving the stability of circuit board processing.

[0032] like Figure 1 As shown, a circuit board processing device with a flipping function is provided, comprising a frame 1, a side plate 2 is symmetrically fixedly connected to the upper surface of the frame 1, two clamping mechanisms 3 are arranged on the opposite sides of the two side plates 2 and above the frame 1, a clamping mechanism 4 is fixedly connected to the upper sides of the opposite sides of the two side plates 2, and a dust cleaning mechanism 5 is arranged below the inner side wall of the frame 1;

[0033] The two clamping mechanisms 3 can ensure that the circuit board will not be displaced or shaken during the processing, thereby improving the stability of the circuit board processing. At the same time, the locking mechanism 4 is set to lock and fix the flipping component during the flipping process of the circuit board, ensuring that the circuit board can maintain a stable position after flipping to a specific angle to facilitate the next processing operation. Finally, the cleaning mechanism 5 can remove dust and impurities generated by the circuit board during the processing, thereby ensuring the processing quality and performance of the circuit board.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, control motors 6 are provided on the opposite sides of the two side panels 2, and transmission rods 7 are fixedly connected to the opposite ends of the output shafts of the two control motors 6. The opposite ends of the two transmission rods 7 extend to the opposite sides of the two side panels 2, and are fixedly connected to gears 1 8. Gears 2 9 are rotatably connected to the opposite sides of the two side panels 2 and located below the two gears 1 8 through a rotating shaft. The outer walls of the two gears 2 9 are respectively meshed with the outer walls of the two gears 1 8. The centers of the opposite sides of the two gears 2 9 are fixedly connected with electric telescopic rods 10. The opposite ends of the output shafts of the two electric telescopic rods 10 are respectively fixedly connected to the two clamping mechanisms 3. The clamping mechanism 3 includes a U-shaped plate 301. The upper surfaces of the two U-shaped plates 301 are provided with electric telescopic rods 2 302. The insides of the two U-shaped plates 301 are slidably connected with clamping plates 303. The centers of the upper surfaces of the two clamping plates 303 are respectively fixedly connected to the bottom ends of the output shafts of the two electric telescopic rods 2 302.

[0035] The two electric telescopic rods 10 can be adjusted in length according to circuit boards of different sizes, so that circuit boards of different sizes can be accurately positioned between the two U-shaped plates 301, so that circuit boards of different sizes can be clamped and fixed, thereby improving the flexibility of the device. Afterwards, the two electric telescopic rods 302 are extended to control the two clamping plates 303 to move downward, and the two clamping plates 303 can stably clamp the circuit boards, which is convenient for operators to perform processing operations and ensures the stability and reliability of the clamping mechanism 3. At the same time, the two control motors 6 are started at the same time to control the two transmission rods 7 to rotate. The two transmission rods 7 drive the two gears 9 to rotate through the two gears 8, and the two electric telescopic rods 10 and the two U-shaped plates 301 can be driven to rotate through the two gears 9, so that the circuit boards can be automatically flipped, thereby improving the convenience and practicality of processing.

[0036] like Figure 2 As shown, the inner lower surfaces of the two U-shaped plates 301 and the lower surfaces of the two clamping plates 303 are fixedly connected with the soft pads 13;

[0037] The multiple soft pads 13 can prevent the hard surfaces of the two U-shaped plates 301 and the two clamping plates 303 from directly contacting the circuit board, thereby causing deformation of the edge of the circuit board, thereby reducing the risk of physical damage and ensuring the surface integrity of the circuit board and the safety of electronic components.

[0038] like Figure 5 and Figure 6As shown, the engaging mechanism 4 includes an engaging box 401, the interiors of the two engaging boxes 401 are slidably connected with T-shaped pieces 402, the bottom ends of the two T-shaped pieces 402 extend to the bottoms of the two engaging boxes 401 respectively, and are fixedly connected with tooth blocks 1 403, the lower surfaces of the two tooth blocks 1 403 are respectively in contact with the upper sides of the outer walls of the two gears 1 8, the inner upper surfaces of the two side plates 2 are fixedly connected with extrusion boxes 404, the interiors of the two extrusion boxes 404 are slidably connected with piston plates 1 405, and the two movable The lower surface of the plug plate 405 is fixedly connected with an oblique block 406, and the bottom ends of the two oblique blocks 406 extend to the bottom of the two extrusion boxes 404 respectively. The outer wall of the transmission rod 7 and the lower part of the oblique block 406 are symmetrically fixedly connected with a rotating block 407, and the outer walls of the two rotating blocks 407 located on the upper part of the two side plates 2 are in contact with the two oblique blocks 406 respectively. The upper surfaces of the two engaging boxes 401 are fixedly connected with a communicating air pipe 408 between the two extrusion boxes 404 respectively.

[0039] By stably engaging the two tooth blocks 403 in the tooth blocks above the two gears 8, the rotation of the two gears 8 is limited, the flipping angle of the circuit board is fixed, and the processing stability is improved. When the circuit board needs to be turned over, the two control motors 6 drive the two transmission rods 7 to rotate to perform the flipping operation on the circuit board. When the two transmission rods 7 rotate, the two rotating blocks 407 on the outside thereof will also be driven to rotate simultaneously. When the circuit board is rotated and turned over, the two rotating blocks 407 at the bottom are rotated to the top to squeeze the two oblique blocks 406. The two oblique blocks 406 drive the two piston plates 405 to slide upward inside the two extrusion boxes 404. The gas inside the extrusion boxes 404 is transported to the inside of the two engaging boxes 401 through the two communicating air pipes 408, which can push the two T-shaped pieces 402 to slide downward. The two tooth blocks 403 can be re-engaged in the tooth blocks above the two gears 8 through the movement of the T-shaped pieces 402, and the rotation of the two gears 8 is continued to be limited, which is convenient for processing the other side of the circuit board, thereby improving the efficiency and convenience of circuit board processing.

[0040] like Figure 5 As shown, the left and right sides of the interior of the extrusion box 404 and above the piston plate 1 405 are fixedly connected with the limit strips 12;

[0041] The limit strip 12 can effectively limit the moving distance of the two oblique blocks 406 , preventing the rotating block 407 from completely squeezing the two oblique blocks 406 into the two squeezing boxes 404 , thereby causing the locking mechanism 4 to fail.

[0042] like Figure 3As shown, the dust cleaning mechanism 5 includes a cleaning box 501, an air pump 502 is arranged at the rear of the frame 1, the front end of the output shaft of the air pump 502 is rotatably connected to the rear surface of the cleaning box 501, a connecting rod 503 is fixedly connected to the center of the front surface of the cleaning box 501, the front end of the connecting rod 503 extends to the front of the frame 1, and is fixedly connected to a rotating disc 2 504, and a plurality of air outlets 505 are arranged on the upper surface of the cleaning box 501;

[0043] When the circuit board is being turned over, the air pump 502 can be started to provide high-pressure gas to the interior of the cleaning box 501. The high-pressure gas is ejected through the multiple air outlets 505. The ejected high-speed airflow directly impacts the surface of the processed side of the circuit board, thereby blowing dust and impurities on the circuit board away from the circuit board to prevent affecting the quality of the circuit board processing.

[0044] like Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, an air box 506 is fixedly connected to the right side of the frame 1, and a piston plate 507 is slidably connected inside the air box 506. A contact plate 508 is fixedly connected to the upper surface of the piston plate 507, and the top of the contact plate 508 extends to the top of the air box 506. A rotating disk 517 is fixedly connected to the outer wall of the transmission rod 7 above the air box 506. The upper and lower outer walls of the rotating disk 517 are fixedly connected with protrusions 509, and the bottom end of the protrusion 509 below the rotating disk 517 contacts the top of the contact plate 508. A control box 510 is fixedly connected to the right side of the front surface of the frame 1, and a piston plate 3 511 is slidably connected inside the control box 510. A moving plate 512 is fixedly connected to the left side of the piston plate 511, and a plurality of tooth blocks 513 are fixedly connected to the lower surface of the moving plate 512. The right side of the box 510 is fixedly connected to the lower surface of the air box 506 with a communicating air pipe 2 514, the front surface of the frame 1 and located above the rotating disc 2 504 is rotatably connected with a gear 3 515 through a rotating shaft, the lower surface of the piston plate 2 507 and the inner lower surface of the air box 506 are fixedly connected with a plurality of springs 2 516, the center of the front surface of the gear 3 515 is fixedly connected with a fixed disk 518, the upper surface of the fixed disk 518 is fixedly connected with a connecting block 519, the front surface of the connecting block 519 is fixedly connected with a round pin 520, the outer wall of the gear 3 515 is meshedly connected with the plurality of tooth blocks 2 513, the center of the front surface of the fixed disk 518 is fixedly connected with a toggle disk 521, the outer wall of the rotating disc 2 504 is fixedly connected with three groove wheels 522, and the outer walls of the three groove wheels 522 are all integrally formed with locking arcs 523;

[0045] When the two control motors 6 drive the two transmission rods 7 to rotate and perform the flipping operation on the circuit board, the right transmission rod 7 can drive the rotating disk 1 517 to rotate simultaneously when it rotates, thereby driving the two protrusions 509 to rotate simultaneously through the rotation of the rotating disk 1 517, and when the lower protrusion 509 rotates to cancel the contact with the resistance plate 508, the two piston plates 2 507 can be controlled to slide upward inside the two air boxes 506 through the rebound of the multiple springs 2 516, and the gas inside the two air boxes 506 is transported to the inside of the two control boxes 510 through the two connecting air pipes 2 514, thereby controlling the piston plate 3 511 to slide rightward, and the moving plate 512 can be retracted by the movement of the piston plate 3 511, and the gear 3 515 can be driven to rotate by the multiple tooth blocks 2 513 under the moving plate 512, and the rotation of the gear 3 515 can control the round pin 520 and the toggle As the disk 521 rotates, the round pin 520 will enter the groove of the groove wheel 522 in turn to push the groove wheel 522 to rotate a certain angle. When the round pin 520 leaves the groove wheel 522, the locking arc 523 plays a role in locking the groove wheel 522 to prevent the groove wheel 522 from rotating at will when not in operation. The rotation of the groove wheel 522 can control the rotating disk 2 504 to rotate together, and the rotating disk 2 504 can be used to control the cleaning box 501 to rotate from right to left, thereby changing the air outlet direction of the multiple air outlets 505, so as to better clean the surface of the circuit board and further improve the processing quality. When the circuit board is flipped and reset, the upper protrusion 509 rotates to the bottom and contacts the resistance plate 508 at the same time, so as to control the moving plate 512 to extend, and at the same time control the cleaning box 501 to rotate from left to right, thereby improving the repeatability and stability of the cleaning operation, thereby ensuring the consistency of the circuit board cleaning quality.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
