Description

Technical Field

[0001] The invention relates to the technical field of board separators, and in particular to a protective automatic board separator for a PCB circuit board. Background Art

[0002] PCB circuit boards are an indispensable key component of modern electronic devices. They provide a method of fixing electronic components on a mechanical carrier and connecting them through wires. These wires are printed from thin film metal materials and inserted into non-conductive substrates according to a predetermined design layout. Through PCB circuit boards, reliable electrical connections can be achieved between electronic components, allowing the equipment to operate normally. When PCB circuit boards are processed, in order to reduce damage and improve processing efficiency, multiple groups of circuit boards are often processed on the same substrate. After the processing is completed, the electronic components are separated by a board separation machine.

[0003] At present, there are roughly three types of PCB depaneling machines: knife-type depaneling machines, stamping-type depaneling machines, guillotine-type depaneling machines and milling-cutting-type depaneling machines, etc. They mainly use mechanical shearing to cut PCB circuit boards. Among them, the knife-type, stamping-type and guillotine-type depaneling machines have low edge accuracy of circuit boards after depaneling, and there are edge burrs, etc. In addition, the blades exert a large force on the circuit boards during the cutting process. The separated circuit boards may splash and fall outside the working area, which hinders the collection of the separated circuit boards. The milling-cutting-type depaneling machine has high depaneling accuracy, but the milling-cutting-type depaneling machine performs depaneling by milling, which produces more milling debris and affects the processing environment. Therefore, we propose a protective automatic depaneling machine for PCB circuit boards, which can automatically depanel PCB circuit boards and reduce the falling of depaneled circuit boards and the generation of dust.

[0063] like Figure 1 to Figure 2 As shown, the blanking box 4 is arranged on the machine body 1, and the protective box 3 is connected with the protective box 3 through the discharge port. The blanking box 4 is located at the rear side of the protective box 3, and the PCB circuit board after the separation is completed enters the blanking box 4 for blanking and feeding.

[0064] like Fig.11As shown, the conveyor belt 5 is arranged on the machine body 1, a through hole for the conveyor belt 5 to pass through is opened on the blanking box 4, and a discharge port is opened on the rear side of the blanking box 4. The PCB circuit board after the separation is dropped onto the conveyor belt 5, and is discharged through the discharge port under the output of the conveyor belt 5 for collection and subsequent processing.

[0065] like Figure 3 and Fig.11 As shown, the conveying mechanism is used to convey the PCB circuit board between the material receiving area, the board separation area and the blanking area. The conveying mechanism includes a conveying table 101, a turning table 102, an air suction port 103 and a vacuum pump 104. A conveying trough is opened on the machine body 1, and the conveying table 101 is movably arranged inside the conveying trough. A guide rail 105 is arranged on the processing platform 6. The conveying table 101 and the guide rail 105 are in sliding cooperation. A motor 106 is arranged inside the blanking box 4, and a lead screw 107 is arranged at the output end of the motor 106. The lead screw 107 is rotatably arranged inside the conveying trough. A nut matching the lead screw 107 is arranged on the conveying table 101, and the turning table 102 is rotatably arranged on the conveying table 101. The turning table 102 is located between the material receiving area and the board separation area. The turning table 102 is in a horizontal state when in the board area, and can be rotated to an inclined state when it moves to the blanking area. A plurality of air suction ports 103 are provided, and the air suction ports 103 are connected to the turning table 102, and the vacuum pump 104 is connected to the turning table 102. The lead screw 107 can be driven to rotate by the motor 106, thereby driving the conveying table 101 to move along the guide rail 105.

[0066] like Figures 4 to 5As shown, in order to realize the flipping of the flipping table 102, a flipping component is also included, and the flipping component is used to drive the flipping table 102 to flip. The flipping component includes a swivel seat 201, a driven gear 202 and a driving rack 203. The swivel seat 201 is arranged on the top of the conveying table 101, and the flipping table 102 is rotatably arranged on the swivel seat 201 through the driving shaft. The driven gear 202 is arranged on the driving shaft, and the driving rack 203 is arranged inside the blanking box 4. The driving rack 203 and the driven gear 202 are meshed. The side of the driving rack 203 close to the protective box 3 is set as a light rod. A magnet 204 is arranged at the bottom of the flipping table 102. The material of the conveying table 101 is iron metal. When the magnet 204 contacts the top of the conveying table 101, The turning table 102 is in a horizontal state, and the stability of the turning table 102 when it is in a horizontal state is ensured by the mutual attraction between the magnet 204 and the conveying table 101. When the lead screw 107 drives the conveying table 101 and the turning table 102 to move to the inside of the blanking box 4, the driven gear 202 first moves to the light rod of the driving rack 203. As the conveying table 101 and the turning table 102 continue to move, the driven gear 202 and the driving rack 203 are engaged, and the driving rack 203 is in a fixed state. As the driven gear 202 moves, the driven gear 202 and the driving shaft rotate, and the driving shaft drives the side of the turning table 102 with the magnet 204 to rotate upward, so that the PCB circuit board after the depaneling slides off the turning table 102.

The inner wall of the storage box 301 is tightly attached to the edge of the PCB circuit board to limit the PCB circuit board. The active rack 306 can be driven to move by the electric cylinder 1 305, thereby driving the passive gear 307 and the rotating shaft 304 to rotate. The vacuum suction cup 303 is at the top of the storage box 301 and is lifted and lowered by the electric cylinder 1 The second electric cylinder 308 drives the vacuum suction cup 303 to descend to adsorb the PCB circuit board. The descending distance of the second electric cylinder 308 can be adjusted to gradually increase the descending distance and stick to the PCB circuit board. The vacuum suction cup 303 is arranged at the output end of the second electric cylinder 308 through a clamping spring and a telescopic rod. Under the action of the clamping spring, the vacuum suction cup 303 is pressed against the surface of the PCB circuit board. At the same time, the elasticity of the clamping spring is used to avoid damage to the PCB circuit board. Then the second electric cylinder 308 drives the vacuum suction cup 303 and the PCB circuit board to rise. The first electric cylinder 305 drives the rotating shaft 304 and the transfer rack 302 to rotate 180 degrees, so that the vacuum suction cup 303 rotates to the top of the flip table 102. The second electric cylinder 308 drives the vacuum suction cup 303 and the PCB circuit board to descend, so that the PCB circuit board is placed above the flip table 102.

A buffer spring 13 and a telescopic rod are arranged between the bottom of the buffer plate 12 and the inner wall of the blanking box 4, and the buffer plate 12 is supported by the buffer spring 13. The end of the buffer plate 12 away from the blanking box 4 is tilted downward, and the PCB circuit board after the board is separated slides onto the buffer plate 12 on the turning table 102, and the PCB circuit board on the buffer plate 12 continues to fall on the conveyor belt 5 for transportation, thereby shortening the falling distance of the PCB circuit board, thereby reducing the impact force when the PCB circuit board slides and reducing the damage of the PCB circuit board. At the same time, there is sliding damping on the telescopic rod, and the impact caused by the falling of the PCB circuit board is buffered and absorbed by the sliding of the telescopic rod and the elasticity of the buffer spring 13, thereby further reducing the damage of the PCB circuit board.
