Description

Technical Field

[0001] The invention relates to the field of circuit boards, and in particular to a circuit board receiving machine. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts.

[0003] After processing, circuit boards are generally stacked together by a board collecting machine. For example, patent application number: CN201921190476.0 discloses a board collecting machine. When the circuit board is transmitted to the guard plate, the photoelectric sensor can sense the circuit board and send a signal to the controller. The controller controls the clapping mechanism to position the circuit board. After the clapping mechanism positions the circuit board, the transfer device absorbs the circuit board and places the circuit board on the receiving rack. This type of board collecting machine stacks the processed circuit boards evenly on the support plate, resulting in the bottom circuit board needing to bear the weight of all the circuit boards above, and the lower circuit board is easily damaged after being compressed.

[0004] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

The processed circuit board moves with the conveyor belt. After the circuit board moves to the rotating slot position, one end of the circuit board is inserted into the rotating slot. After the circuit board is fixed in the rotating slot, the cylinder starts, the piston rod on the cylinder shortens, and the rack moves. Since the rack is meshed with the gear, when the rack moves, the gear rotates, and the rotating shaft rotates with the gear. The rotating slot rotates around the rotating shaft. After the circuit board rotates with the rotating slot to be parallel to the upper limit plate of the bracket, the material collection motor starts, and the material collection motor drives the lead screw to rotate. Since the lead screw is threadedly connected to the slide plate, when the lead screw rotates, the slide plate moves, and the slide plate moves in the direction of the lead screw, and the circuit board moves with the slide plate. After the circuit board moves to the specified position, the material collection motor stops, the lifting cylinder starts, the piston rod on the lifting cylinder shortens, the support plate tilts down, the rotating slot tilts down, and the circuit board tilts down with the rotating slot. After contacting the limit bar, it is blocked by the limit bar, and the circuit board stops on the limit bar, and the circuit board leans against the limit plate. After the rotating groove is separated from the circuit board, it reaches the bottom of the circuit board, the cylinder starts, the piston rod on the cylinder extends, and the rotating groove rotates around the rotating axis to a horizontal state, the material receiving motor starts, and the material receiving motor drives the lead screw to rotate in the opposite direction, and the slide plate returns to the initial position, the lifting cylinder starts again, the piston rod on the lifting cylinder extends, the support plate rises, and the rotating groove rises to the initial position with the support plate, and the next processed circuit board arrives in the rotating groove again, and the circuit board is placed on the limit bar again, and the operation is cyclic. Through this device, the circuit boards can be placed one by one on the limit bar of the bracket, and the bottom of each circuit board is supported by the limit bar. The pressure on the circuit board is small, which can effectively avoid damage to the circuit board after being compressed.

[0008] Preferably, the lifting cylinder is fixed on the slide plate at an angle. The lifting cylinder is fixed at an angle, so that the circuit board placed on the limit bar can be tilted down to avoid collision between circuit boards.

[0009] Preferably, the rotating mechanism comprises a cylinder fixed on the supporting plate, a rack is fixed to the end of the piston rod of the cylinder, a gear is also fixed on the rotating shaft, and the rack is meshed with the gear.

[0010] Preferably, the positioning plate is fixed with a plurality of positioning posts, and the fixing plate of the bracket is provided with positioning holes at positions corresponding to the positioning posts. When the bracket is placed on the positioning plate on the rack, the positioning holes on the bracket are assembled with the positioning posts on the positioning plate to achieve positioning and fixing of the bracket on the rack.

[0011] Preferably, the upper end of the limit strip is evenly fixed with limit teeth, which can effectively prevent the circuit board from sliding by increasing the friction between the circuit board and the limit strip through the limit teeth.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The device can be used to place the circuit boards one by one on the limiting strips of the bracket. The limiting strips support the bottom of each circuit board, so that the circuit boards are subjected to little pressure, which can effectively prevent the circuit boards from being damaged after being subjected to pressure.
