[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.

The flipping mechanism 2 comprises a rotating drum 5, wherein 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, and 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, and the two through grooves 10 are respectively connected with the inside of the two side grooves 7, and 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, and transmission grooves 13 are provided on the left and right sides of the clamps 12, and a plurality of electric rollers 14 are arranged inside the transmission groove 13, A through plate groove 15 is provided at 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.

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 convex brackets 21 are fixed on the opposite 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 convex bracket 21 respectively; the flipping machine is placed between the two transmission mechanisms. When the circuit board processed on one side enters the flipping 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 used, the two cylinders 11 are adjusted: the two clamping frames 12 move relatively with each other, and the telescopic plate 19 moves with it during the movement, and the arc plate 20 is driven to slide along the annular groove 9 through the telescopic plate 19, and the telescopic plate 19 slides out with it. Since the telescopic 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 telescopic plate 19, the arc plate 20, the telescopic plate 19, and the clamping frame 12 are kept 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, so as to fit the front and back sides of the circuit board to avoid sliding deviation when the circuit board is turned over, and the two clamping frames 12 fit the upper and lower surfaces of the circuit board through the electric roller 14; when the rotating drum 5 and the circuit board are rotated and turned over, the electric roller 14 operates to transport the circuit board out of the flipping mechanism 2.

[0035] Reference Figure 5The 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, two brackets 26 are fixed on the outer surfaces of the two ring frames 25, the two brackets 26 are respectively located at the front and rear of the ring frames 25, and the two ends of the bottom of the bracket 26 are slidably connected with slide bars 27, and the four slide bars 27 are fixedly connected to the bottom plate 23. A track 28 is provided below the bottom plate 23, and 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, and 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, and the two vertical frames 31 are internally connected to the spur gear 32 for common rotation. A tooth groove 33 is provided on the upper surface of the track 28, and the drum 5 The outer surface is provided with a plurality of tooth grooves 2 34, and the top and bottom ends of the spur gear 1 32 are meshed and connected with the tooth grooves 2 34 and the tooth grooves 1 33 respectively. When the cylinder 24 is extended and retracted, the overturning mechanism 2 is lifted and lowered through the bracket 26 and the ring frame 25, so that the device can adapt to the transmission mechanisms of different heights on both sides; and when the rotating drum 5 rotates, the tooth grooves 2 34 on its surface are used to rotate the spur gear 1 32, and the tooth grooves 1 33 drive the bottom plate 23, the bracket 26 and other structures to drive the overturning mechanism 2 to move along the slide rail 29 through the roller 30, adjust the position, and transport the overturned circuit board to the conveyor belt next to it for the next step of processing. After the transmission, the resetting rotating drum 5 that rotates in the opposite direction reverses through the spur gear 1 32 to reset the device for continuous operation;

[0036] A shaft frame 36 is fixed to the front of the outer surface of the two ring frames 25, and a shaft rod 37 is connected to the two shaft frames 36 for common rotation. A spur gear 2 38 is fixed to the outer surface of the shaft rod 37, and baffles 39 are fixed to the left and right ends of the shaft rod 37. The baffles 39 arranged at the front and rear can prevent the circuit board from accidentally sliding out when the circuit board is turned over, causing damage to the circuit board;

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

The baffle 39 at the rear still keeps the protective shielding to the rear while rotating, until the circuit board completes the intermittent flipping movement. At this time, the baffle 39 at the rear no longer blocks the rear outlet, so that the flipped circuit board can be easily transported out.

[0040] When the drum 5 rotates, the spur gear three 42 is rotated through the tooth grooves two 34 on its surface, and drives the shaft rod two 41 and the two bevel gears one 43 to rotate. The bevel gear one 43 is transmitted through the bevel gear two 46 to rotate the shaft rod three 45 and the wind wheel 47. 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, so as to better blow away the dust generated by processing on the circuit board or the dust in contact with the conveyor belt, so that the production and processing on the other side can be carried out 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. The outer surfaces of the two transmission wheels 4 are both 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, so that the circuit board carried inside is flipped.

[0042] Reference Figure 3-4 A guide rod 17 is slidably connected inside 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 forward and backward stably.

The arc plate 20 is an arc-shaped structure, and the cross-section of the ring frame 25 is an L-shaped structure. The outer surface of the positioning plate 16 is in contact with the inner surfaces of the two plate grooves 15.
