[0002] PCB board, also known as printed circuit board, is not only the support of electronic components but also the carrier of electrical connection. Among them, PCB board is extremely fragile in the production process. Specifically, dust in the air falls on the PCB board, or workers touch it with bare hands, or scratches by hard objects, or friction between PCB boards, etc., will cause certain damage to the PCB board, which leads to the low yield rate of PCB board production. For this reason, in the production process of PCB boards, a layer of plastic protective film is covered on the surface of the PCB board to protect the PCB board.

In order to better remove the film from the surface of the PCB board, the existing removal method generally adopts a manual removal processing method. This removal method is relatively traditional, which greatly reduces the production efficiency of the PCB board.

The static electricity removal mechanism 20 is used to separate the PCB board 101 and the film 102 on the working position 11. The transfer mechanism 10 includes a transverse movement component 12, a lifting component 13 and a suction cup component 14. The suction cup component 14 is connected to the lifting component 13. The lifting component 13 is slidably connected to the transverse movement component 12. The lifting component 13 is used to drive the suction cup component 14 to make horizontal reciprocating motion at both ends of the transverse movement component 12. The suction cup component 14 is used to absorb and transfer the PCB board 101 on the working position 11.

[0024] In the present embodiment, a PCB protective film removal device further comprises an equipment frame, a transfer mechanism 10 is arranged above the equipment frame, the transfer mechanism 10 is bolted and fixed to the equipment frame, a conveying mechanism 30 and a static electricity removal mechanism 20 are arranged on the upper end surface of the equipment frame, and the conveying mechanism 30 and the static electricity removal mechanism 20 are bolted and fixed to the equipment frame respectively, in addition, a working position 11 is arranged on the equipment frame, and the conveying mechanism 30 is located below one end of the transfer mechanism 10, the working position 11 is located below the other end of the transfer mechanism 10, and the static electricity removal mechanism 20 is located between the working position 11 and the conveying mechanism 30, specifically, the working position 11 is used for The flat pallet fixture of the B board 101 is fixed and limited, and the transfer mechanism 10 is used to grab and lift the PCB circuit board 101 at the working position 11 and then move it horizontally to the conveying mechanism 30, wherein the static electricity removal mechanism 20 is used to remove the static electricity of the protective film on the PCB circuit board 101 lifted to a specified height. Therefore, through the structural arrangement of the static electricity removal mechanism 20, the transfer mechanism 10 and the conveying mechanism 30, the utility model can remove the protective film adsorbed on the PCB circuit board 101 and transfer it to the equipment of the next process. Compared with manual removal, the utility model is more efficient in removing the protective film adsorbed on the PCB circuit board 101.

In addition, after the film 102 is separated from the PCB circuit board 101, the lifting component 13 continues to lift the suction cup assembly 14 and the circuit board 101, and then combines with the lateral movement component 12 to drive the lifting component 13, the suction cup assembly 14 and the circuit board 101 to move toward the conveying mechanism 30. After arriving above the conveying mechanism 30, the lifting component 13 drives the suction cup assembly 14 and the circuit board 101 to descend to the upper end surface of the conveying mechanism 30, and then combines with the suction cup assembly 14 to remove the vacuum so that the circuit board 101 falls on the conveying mechanism 30.

[0027] In the present embodiment, the static eliminator 21 is in the shape of a rod, and is arranged in a longitudinal direction perpendicular to the longitudinal direction of the transverse moving component 12. Specifically, a high-pressure air duct is arranged in the static eliminator 21, and one end of the high-pressure air duct is connected to the high-pressure connector 211, so that the static eliminator can be connected to the high-pressure fan through the high-pressure connector 211, and the high-pressure air is delivered to the high-pressure air duct through the high-pressure fan, wherein the static eliminator is provided with a plurality of air nozzles 212 arranged at equal intervals on one side of the working position 11, and the air nozzles 212 are connected to the high-pressure air duct, so that the high-pressure air in the high-pressure air duct is evenly blown to the circuit board 101 lifted above the working position 11 through the air nozzles 212. It should be explained that the static eliminator Charged particles will be generated in the eliminator 21, so that the high-pressure wind will form high-speed ion wind after passing through the high-pressure air duct and blow through the wind nozzle 212 to the PCB circuit board 101 adsorbed with the film 102. To be more specific, the charged particles will neutralize the charge carried between the film 102 and the circuit board 101, thereby achieving the effect of eliminating static electricity. Combined with the action of high-speed wind, the film 102 after static electricity is eliminated will be blown away from the circuit board 101. Compared with manually removing the film 102 on the circuit board 101, this method of removing the film 102 can better protect the surface of the circuit board 101, reduce the contact between the object and the circuit board 101, and at the same time, improve the efficiency of removing the film 102.

[0028] For further reference, Figure 1 , Figure 3 and Figure 4 The static electricity removal mechanism 20 also includes a lifting bracket 22 and a first cylinder 23 both located below the static electricity eliminator 21. The first cylinder 23 is connected to the lifting bracket 22, and the output end of the first cylinder 23 is connected to the static electricity eliminator 21. The first cylinder 23 is used to lift and adjust the height of the static electricity eliminator 21.

[0029] In this embodiment, the lifting bracket 22 is abutted against the upper end surface of the equipment frame and fixed by bolts, and the first cylinder 23 is abutted against the upper end surface of the equipment frame and connected and fixed, that is, during the operation, the positions of the lifting bracket 22 and the first cylinder 23 are relatively static. Specifically, the output end of the first cylinder 23 is screwed to the lower end of the static eliminator 21, and the telescopic axis of the first cylinder 23 is telescoped and lifted in the vertical direction, thereby driving the static eliminator 21 to move up and down relative to the lifting bracket 22, so that the static eliminator 21 can remove static electricity from the film 102 on the circuit board 101 lifted to different heights, thereby improving the practicality of the utility model.

[0031] In this embodiment, guide holes are provided at both ends of the lifting bracket 22 in the vertical direction, and guide columns 24 are arranged in the guide holes. The guide columns 24 are slidably connected to the lifting bracket 22, and one end of the guide column 24 is connected and fixed to the lower end of the lifting bracket 22, and the other end is arranged through the guide hole. When the lifting bracket 22 drives the static eliminator 21 to move up and down, the guide column 24 is extended into the guide hole to limit the lifting of the lifting bracket 22 in the horizontal direction, thereby improving the lifting stability of the static eliminator 21 to a certain extent.

[0032] For further reference, Figure 1 and Figure 2 The transverse movement assembly 12 includes a horizontal slide rail 121, a sliding motor 122 and a horizontal slider 123.

The sliding motor 122 is used to drive the horizontal slider 123 and the lifting assembly 13 to make horizontal reciprocating movements at both ends of the horizontal slide rail 121.

[0033] In this embodiment, one side of the horizontal slide rail 121 is in contact with the equipment frame and fixed by bolts, and the other side is provided with a horizontally arranged slide rail, and the horizontal slider 123 is adapted to the slide rail, wherein the sliding motor 122 is bolted and fixed to one end of the horizontal slide rail 121 close to the working load position 11. Specifically, the output end of the sliding motor 122 is connected and fixed to the horizontal slider 123, and the sliding motor 122 drives the horizontal slider 123 to move along the horizontal direction of the horizontal slide rail 121, that is, the horizontal slider 123 is slidingly connected to the horizontal slide rail 121. In addition, the horizontal slider 123 is connected and fixed to the lifting assembly 13, so that the sliding motor 122 can drive the horizontal slider 123 to drive the PCB circuit board 101 to move from above the working load position 11 to above the conveying mechanism 30, thereby completing the horizontal movement of the demolding PCB circuit board 101 of the utility model.

[0034] For further reference, Figure 1 and Figure 2The lifting assembly 13 includes a second cylinder 131, a vertical slide rail 132 and a lifting bracket 133. The second cylinder 131 is connected to the vertical slide rail 132. The lifting bracket 133 is slidably connected to the vertical slide rail 132. The lifting bracket 133 is connected to the output end of the second cylinder 131, and the lifting bracket 133 is connected to the suction cup assembly 14. The second cylinder 131 is used to drive the lifting bracket 133 and the suction cup assembly 14 to perform vertical lifting and reciprocating motion at both ends of the vertical slide rail 132.

[0035] The lifting bracket 133 is driven by the second cylinder 131 to perform lifting and lowering movement in the vertical direction, that is, the lifting bracket 133 is slidably connected to the vertical rail 132. In addition, the lifting bracket 133 is connected and fixed to the suction cup assembly 14 at one end away from the vertical rail 132, so that the PCB circuit board 101 is lifted and lowered as the lifting bracket 133 is lifted and lowered, thereby making it easier to lift the circuit board 101 from the working position 11 or to lower the circuit board and place it above the conveying mechanism 30, so that the utility model can complete the vertical lifting and lowering of the PCB circuit board 101 after demolding.

[0036] For further reference, Figure 1 and Figure 2 The suction cup assembly 14 includes a vacuum generator 141 and a suction plate 142. The vacuum generator 141 is connected to the lifting bracket 133. The suction plate 142 is located at the lifting bracket 133 and is connected and fixed thereto.

The vacuum suction nozzles 143 are used to vacuum the PCB circuit board 101.

In addition, a plurality of vacuum suction nozzles 143 are arranged at equal intervals around the circumference of the suction plate 142 so as to uniformly vacuum-absorb and grasp the PCB circuit board 101. Specifically, the vacuum suction nozzle 143 is connected to the vacuum generator 141 pipeline. After the lifting component 13 is lowered to make the vacuum suction nozzle 143 abut against the upper end surface of the PCB circuit board 101 with the plastic protective film 102 attached thereto, the vacuum generator 141 is evacuated so that the vacuum suction nozzle 143 generates vacuum suction on the circuit board 101. Then, the lifting component 13 is combined to lift the suction cup assembly 14 and the circuit board 101 to the designated position matched with the air nozzle 212, and the static eliminator 21 is started. And blow out high-speed ion wind to neutralize the charge between the film 102 and the circuit board 101, and blow the film 102 to the waste collection box 40, then the lifting component 13 drives the circuit board 101 to continuously lift to the specified height of horizontal movement, the transverse movement component 12 drives the lifting component 13 to move horizontally above the conveying mechanism 30, the lifting component 13 drives the circuit board 101 down to the upper end surface of the conveying mechanism 30, and the vacuum generator 141 releases the vacuum to separate the suction nozzle from the circuit board 101, thereby completing the removal of the film 102 and the transfer of the PCB circuit board 101. Compared with manual transfer, the utility model has a higher efficiency in removing the film 102. In addition, through the structural setting of the transverse movement component 12, the lifting component 13 and the suction cup component 14, the direct contact with the circuit board 101 can be reduced, and the risk of friction damage to the surface of the circuit board 101 is reduced.
