It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0031] 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.

[0032] Reference Figure 1-6A turnover machine for circuit board processing includes a support mechanism 1, wherein the support mechanism 1 is internally connected to a turnover mechanism 2, two motors 3 are fixed on the upper surface of the support mechanism 1, and a transmission wheel 4 is fixed to the output shaft of the motor 3. The turnover mechanism 2 includes a rotating drum 5, an inner groove 6 is provided inside the rotating drum 5, and side grooves 7 are provided on the front and rear sides of the inner surface of the inner groove 6. A rod groove 8 is provided on the inner surface of the side groove 7. An annular ring groove 9 is provided on the left and right sides of the rotating drum 5, and two through-type through grooves 10 are provided on the inner side wall of the ring groove 9. The two through grooves 10 are respectively connected to the inside of the two side grooves 7. Cylinders 11 are fixed on the upper and lower sides of the inner groove 6, and clamps 12 are fixed on the opposite ends of the two cylinders 11. Transmission grooves 13 are provided on the left and right sides of the clamp 12, and a plurality of electric rollers 14 are provided inside the transmission groove 13. A through plate groove 15 is provided on the front and rear sides of the upper surface of the clamping frame 12, and a positioning plate 16 is slidably connected inside the upper and lower plate grooves 15. A slide groove 18 is symmetrically provided on the left and right sides of the clamping frame 12, and a telescopic plate 19 is slidably connected inside the slide groove 18. Four arc plates 20 are slidably connected inside the annular groove 9. The end of the telescopic plate 19 away from the clamping frame 12 is rotatably connected to the outer surface of the adjacent arc plate 20. Four protrusions 21 are fixed on the back sides of the two positioning plates 16. Two connecting rods 22 are provided inside the through groove 10, and the two ends of the connecting rod 22 are rotatably connected to the arc plate 20 and the protrusion 21 respectively; the flip machine is placed between the two transmission mechanisms. When the circuit board processed on one side enters the flip mechanism 2 for flipping, it moves from the other side to the other transmission mechanism and is transmitted for the next processing step;

[0033] The motor 3 operates to cause the flip mechanism 2 and the circuit board to rotate half a circle through friction of the transmission wheel 4, so that the processing side of the circuit board is located at the top;

[0034] According to the different sizes and thicknesses of circuit boards, when adjusted for use: the two cylinders 11 operate synchronously to extend and retract, so that the two clamping frames 12 move relative to each other, and the retractable plate 19 moves accordingly during the movement, and drives the arc plate 20 to slide along the annular groove 9 through the retractable plate 19, and the retractable plate 19 slides out accordingly. Because the retractable plate 19 is connected, after the cylinder 11 pushes and pulls the clamping frame 12 and drives the arc plate 20 to move through the retractable plate 19, the arc plate 20, the retractable plate 19, and the clamping frame 12 remain at the same horizontal height. When the height of the clamping frame 12 is fixed, the arc plate 20 is also affected and locked and will not slide. After moving, the positioning plate 16 is pushed by the connecting rod 22 to move close to the circuit board, thereby fitting the front and back sides of the circuit board to prevent sliding deviation when the circuit board is flipped, and the two clamping frames 12 are fitted with the upper and lower surfaces of the circuit board through the electric roller 14; when the rotating drum 5 and the circuit board rotate and flip, the electric roller 14 operates to transport the circuit board out of the flip mechanism 2.

[0035] Reference Figure 5, the support mechanism 1 includes a bottom plate 23, two cylinders 24 are fixed on the upper surface of the bottom plate 23, a ring frame 25 is fixed on the top of the cylinder 24, and two brackets 26 are fixed on the outer surfaces of the two ring frames 25. The two brackets 26 are respectively located in the front and rear of the ring frames 25. Both ends of the bottom of the bracket 26 are slidably connected with slide rods 27. The four slide rods 27 are fixedly connected to the bottom plate 23. A track 28 is provided under the bottom plate 23. Two slide rails 29 are provided on the upper surface of the track 28. The left and right sides of the bottom plate 23 are rotatably connected with rollers 30. The rollers 30 are located inside the slide rails 29. Vertical frames 31 are symmetrically fixed on the upper surface of the bottom plate 23. The two vertical frames 31 are internally connected to a spur gear 32 for common rotation. A tooth groove 33 is provided on the upper surface of the track 28. The rotating drum 5 The outer surface is provided with a plurality of tooth grooves 34, and the top and bottom ends of the spur gear 32 are meshedly connected with the tooth grooves 34 and the tooth grooves 33, respectively. When the cylinder 24 is extended and retracted, the bracket 26 and the ring frame 25 are used to raise and lower the flip mechanism 2, thereby adapting the device to the transmission mechanisms of different heights on both sides. In addition, when the rotating drum 5 rotates, the tooth grooves 34 on its surface cause the spur gear 32 to rotate, and the tooth grooves 33 drive the bottom plate 23, the bracket 26 and other structures to drive the flip mechanism 2 to move along the slide rail 29 via the roller 30, adjust the position, and transport the flipped circuit board to the adjacent conveyor belt for the next step of processing. After transportation, the resetting rotating drum 5 rotates in the opposite direction, resetting the device through the spur gear 32, and continuing the operation.

[0036] A shaft frame 36 is fixed to the front of the outer surface of each of the two ring frames 25. A shaft rod 37 is connected to the inner surface of the two shaft frames 36 for common rotation. A spur gear 38 is fixed to the outer surface of the shaft rod 37. Baffles 39 are fixed to the left and right ends of the shaft rod 37. The front and rear baffles 39 can prevent the circuit board from accidentally sliding out when the circuit board is flipped, causing damage to the circuit board.

[0037] A shaft frame 2 40 is fixed to the rear of the outer surface of each of the two ring frames 25. A shaft rod 2 41 is connected to the interior of the two shaft frames 2 for mutual rotation.

A shaft frame 3 44 is fixed to the rear end of the shaft frame 2 40. A shaft rod 3 45 is connected to the interior of the shaft frame 3 44 for mutual rotation. A wind wheel 47 and a bevel gear 2 46 are fixed to the outer surface of the shaft rod 3 45 in sequence from front to back. The bevel gear 2 46 is meshed with the bevel gear 1 43. An air outlet 35 is formed inside the bevel gear 2 46.

[0038] Spur gear three 42 and spur gear two 38 are both meshed and connected with tooth groove two 34;

[0039] When the drum 5 rotates, the tooth groove 2 34 on its surface causes the spur gear 2 38, the shaft 1 37 and the two baffles 39 to rotate, and the baffle 39 that blocks the rear rotates and opens. The rear baffle 39 still maintains the protective shielding of the rear while rotating until the circuit board completes the intermittent flipping movement. At this time, the rear baffle 39 no longer blocks the rear outlet, and the flipped circuit board can be easily transported out.

[0040] When the drum 5 rotates, the tooth groove 2 34 on its surface causes the spur gear 3 42 to rotate, and drives the shaft 2 41 and the two bevel gears 1 43 to rotate. The bevel gear 1 43 is transmitted through the bevel gear 2 46 to cause the shaft 3 45 and the wind wheel 47 to rotate. The rotating wind wheel 47 can blow air toward the surface of the circuit board inside the drum 5, and blow when the circuit board is turned over, which can better blow away the dust generated by processing on the circuit board or the dust in contact with the conveyor belt, so that the other side can be processed with higher quality.

[0041] Reference Figure 2-5 The two ring frames 25 are respectively located on the left and right sides of the rotating drum 5, and the two ring frames 25 are rotatably connected to the rotating drum 5. The upper surface of the ring frames 25 is fixedly connected to the motor 3, and the outer surfaces of the two transmission wheels 4 are in contact with the upper surface of the outer surface of the rotating drum 5. When the motor 3 operates, the rotating transmission wheel 4 causes the flipping mechanism 2 to rotate half a circle, causing the circuit board carried inside to flip.

[0042] Reference Figure 3-4 A guide rod 17 is slidably connected to the inside of the rod groove 8, and the guide rod 17 is fixedly connected to the positioning plate 16. Under the guidance of the guide rod 17 and the rod groove 8, the positioning plate 16 can move back and forth stably.

[0043] Reference Figure 2-5 The bracket 26 is an H-shaped structure, and the two ends of the top of the bracket 26 are fixedly connected to the two ring frames 25 respectively. The arc plate 20 is an arc-shaped structure, and the cross-section of the ring frame 25 is an L-shaped structure.
