In detail, the transfer mechanism 140 has an adsorption component 220 for adsorbing and fixing the circuit board, that is, the circuit board is fixed by negative pressure adsorption, a horizontal clamping mode is not needed, and the influence of the specification of the circuit board is avoided, so that the plate placing machine can be widely applied.

In some preferred embodiments, the suction assembly 220 may have a suction nozzle 230, a negative pressure pipe 240 connected to the suction nozzle 230, and a permanent magnet 250 fixing the suction nozzle 230.

Therefore, the position of the suction nozzle 230 can be easily adjusted to adapt to the situation that the positions of the holes on the circuit board are different.

In some preferred embodiments, the suction assembly 220 may have a C-shaped bracket, the top end of the C-shaped bracket is connected to the permanent magnet 250, the bottom end of the C-shaped bracket is provided with the suction nozzle 230, and the inside of the C-shaped bracket accommodates the negative pressure tube 240.

Therefore, the negative pressure pipe 240 is reasonably arranged, the positions of the adjacent adsorption nozzles 230 are reduced, the arrangement requirement is met, meanwhile, a plurality of circuit boards are conveniently adsorbed in a limited space, and the board placing efficiency is improved.

In order to transfer the circuit board to the conveying mechanism 100, the transferring mechanism 140 further has a power assembly 260 for lifting and translating the circuit board, that is, a power assembly 260 for lifting and translating the suction assembly 220.

Specifically, the power assembly 260 has a movable frame 290 and a fixed frame 300, the movable frame 290 mounts the suction assembly 220, that is, the movable frame 290 is used for taking and placing the circuit board, and the fixed frame 300 is fixed on the ground or fixed with the frame body of the conveying mechanism 100.

In detail, in some preferred embodiments, a first pin 310 and a first slide 320 for receiving the first pin 310 may be disposed between the movable frame 290 and the fixed frame 300, and the first slide 320 has a vertical slide groove 330 and a horizontal slide groove 340 which are communicated with each other.

That is, the first pin 310 moves in the first slide 320, and then the first pin 310 moves in the vertical chute 330 to realize the lifting of the circuit board, and the first pin 310 moves in the horizontal chute 340 to realize the translation of the waterway board of the circuit board.

Moreover, the height of the vertical chute 330 and the length of the horizontal chute 340 can be processed and adjusted according to the requirements, and the manufacture is convenient.

Referring to fig. 2, the movable frame 290 is provided with a first pin 310, the fixed frame 300 is provided with a first slide 320, the horizontal sliding groove 340 is arranged at the top of the vertical sliding groove 330, and the horizontal sliding groove 340 is arranged at one side of the vertical sliding groove 330 close to the conveying belt 110.

Thus, it is understood that the circuit board may be lifted and then translated onto the conveyor mechanism 100.

Since the first pin 310 and the first slide 320 move relative to each other, the first slide 320 may be provided on the movable frame 290 and the first pin 310 may be provided on the fixed frame 300.

At the same time, the relative positions of the horizontal chute 340 and the vertical chute 330 also need to be adapted to change.

Of course, the structure of the transfer mechanism 140 is not limited to the above-described structure, and may be a combination of two perpendicular air cylinders, a combination of two perpendicular ball screws, a combination of an air cylinder and a screw, or the like.

In some preferred embodiments, the power assembly 260 may have an interconnected horizontal rail 270 and vertical rail 280.

Therefore, the movable frame 290 is limited, so that the circuit board is kept horizontal in the transferring process and is not easy to fall off from the adsorption component 220.

As for the horizontal guide 270 directly connected to the movable frame 290 or the vertical guide 280 connected to the movable frame 290, it is not difficult, and as shown in fig. 2, the horizontal guide 270 connected to the vertical guide 280 and the vertical guide 280 connected to the movable frame 290 are adopted.

In some preferred embodiments, the second sliding path 360 may have a circumferential sliding groove, such that the circumferential sliding groove is located on one side of the radial sliding groove 370 away from the center of the swing arm 350, and thus, when the first pin 310 is switched between the horizontal sliding groove 340 and the vertical sliding groove 330, the acting force direction of the swing arm 350 and the first pin 310 is changed, and the resistance is reduced.

Referring to fig. 2, preferably, the circumferential sliding groove extends upward of the radial sliding groove 370.

In some preferred embodiments, the power assembly 260 may also have a return spring for lifting the movable frame 290.

Of course, in order to avoid the first motor 170 from repeatedly turning, the driving shaft 180 may be provided with a crank link structure connected to the swing arm 350.

Thus, the rotational motion of the driving shaft 180 is converted into the reciprocating swing motion, and the reverse direction of the first motor 170 is prevented.

The eccentric wheel 190 may be an eccentric circular wheel or an elliptical wheel, etc., which meets the transmission requirement.

The pressing mechanism 150 may also have a curtain plate or curtain, so as to close the space above the pressing roller 160, reduce the chance of the outside touching the transferring mechanism 140, and reduce the safety risk.

Thus, the present embodiment has the following effects:

in the embodiment, the pressing mechanism 150 is arranged above the feeding guide roller 120, and the pressing mechanism 150 has the pressing roller 160 for clamping and conveying the circuit board with the conveying belt 110, so that the transferring mechanism 140 only needs to place a part of the circuit board on the conveying belt 110, and then the conveying belt 110 and the pressing roller 160 clamp and convey the circuit board, therefore, the transferring mechanism 140 does not need to place the circuit board on the conveying belt 110 completely, accordingly, the movement range of the transferring mechanism 140 is reduced, the occupied space of the transferring mechanism 140 is reduced, meanwhile, the length of the conveying belt 110 can be shortened, further, the length specification of the plate placing machine along the conveying direction of the conveying belt 110 is reduced, the occupied space of the plate placing machine is reduced, the plate placing machine is compact in structure, and the occupied space is small.
