[0055] S300: the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 slide relative to each other, driving the light shielding sheet 310 to separate from the working position of the slot-type photoelectric 410;

[0056] S400: When the slot-type photoelectric device detects that the light shielding sheet 310 is separated from the working position of the slot-type photoelectric device 410, the PCB board picking device for preventing material jamming stops working and alarms;

[0057] S500: After the operator processes the stuck PCB board, the anti-jamming PCB board picking device is reset.

[0058] Specifically, in this embodiment, refer to Figure 3 The PCB board material removal device for preventing material jamming is fixedly connected to the power component through the connection hole 440 and the connection rod 420 set on the slot-shaped photoelectric fixing plate 400. The power component is used to apply a backward pulling force to the slot-shaped photoelectric fixing plate 400. Figure 1 , Figure 2 and Figure 3 The anti-stuck PCB board material picking device includes: a picking jaw 100, a jaw cylinder 200, a cylinder fixing plate 300, a slot-type photoelectric fixing plate 400, and a magnetic mechanism 500, wherein the picking jaw 100 includes an upper picking jaw 110 and a lower picking jaw 120, both of which are transmission-connected to the jaw cylinder 200, an anti-static engineering plastic baffle 340 is arranged between the upper picking jaw 110 and the lower picking jaw 120, and the opening and closing of the picking jaw 100 is controlled by the jaw cylinder 200, so as to control the picking, the jaw cylinder 200 is arranged on the cylinder fixing plate 300, and the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 are slidably connected through a linear rail 330 arranged on the cylinder fixing plate 300 and a linear rail groove 430 arranged on the slot-type photoelectric fixing plate 400; the cylinder fixing plate 3 00 is provided with a shading sheet 310, and the groove-type photoelectric fixing plate 400 is provided with a groove-type photoelectric 410. The shading sheet 310 is located at the working position of the groove-type photoelectric, and the working position of the groove-type photoelectric 410 is in the groove of the groove-type photoelectric 410. The shading sheet 310 can just block the photoelectric path in the groove of the groove-type photoelectric 410, thereby preventing the groove-type photoelectric 410 from generating an electrical signal; the cylinder fixing plate 300 and the groove-type photoelectric fixing plate 400 are adsorbed and connected by a magnetic mechanism 500, and the magnetic mechanism 500 includes: a magnet 521, a suction block 510, and a magnet fixing seat 520, wherein the magnet fixing seat 520 is fixedly connected to the cylinder fixing plate 300, the magnet is fixed to the magnet fixing seat 520, the suction block 510 is fixedly connected to the groove-type photoelectric fixing plate 400, and the suction block 510 is adsorbed and connected to the magnet 521.

[0059] In the initial state of the device, the upper material picking jaw 110 and the lower material picking jaw 120 of the material picking jaw 100 are in a separated state, that is, the material picking jaw 100 is open, and the power component pushes the device as a whole to a suitable material picking position, that is, the PCB board to be picked up is located between the upper material picking jaw 110 and the lower material picking jaw 120. At this time, the jaw cylinder 200 drives the upper material picking jaw 110 and the lower material picking jaw 120 of the material picking jaw 100 to close, so that the material picking jaw 100 clamps the PCB board, and the anti-static engineering plastic baffle 340 limits the PCB board. Then the power component applies force to the material picking jaw 100 through the slot-type photoelectric fixing plate 400. When a pulling force is applied backwards, if a jam occurs when the PCB board is pulled backwards, the magnetic mechanism 500 fails, that is, the adsorption connection between the suction block 510 and the magnet 521 fails, the suction block 510 and the magnet 521 separate, and the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 are separated. Specifically, when the pulling force applied by the power component to the slot-type photoelectric fixing plate 400 is greater than the magnetic force between the suction block 510 and the magnet, it is determined that a jam occurs, and the suction block 510 and the magnet 521 separate under the action of the pulling force, driving the cylinder fixing plate 300 to separate from the slot-type photoelectric fixing plate 400, allowing the cylinder fixing plate 300 to separate from the slot-type photoelectric fixing plate The plate 400 slides relatively, preferably, the magnetic threshold between the suction block 510 and the magnet 521 is 12N, that is, when the pulling force of the power component is greater than 12N, the suction block 510 and the magnet 521 are separated under the pulling force, and the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 slide relatively along the linear track 330, that is, the slot-type photoelectric fixing plate 400 slides backward along the linear track 330 under the pulling force of the power component, thereby driving the shading sheet 310 to slide backward, so that the shading sheet 310 is separated from the working position of the slot-type photoelectric 410, so that the shading sheet 310 cannot block the light in the slot of the slot-type photoelectric 410 The electrical path, the slot-type photoelectric 410 generates an electrical signal, and the anti-stuck PCB board material picking device also includes a three-color lamp, which is electrically connected to the slot-type photoelectric 410; the slot-type photoelectric 410 is also electrically connected to the clamping claw cylinder 200, and the slot-type photoelectric 410 is also electrically connected to the power component; the electrical signal generated by the slot-type photoelectric 410 is output to the power component, the power component is locked and no longer applies tension, so that the device stops running, and at the same time, the electrical signal generated by the slot-type photoelectric makes the clamping claw cylinder 200 adjust the material picking claw 100, and the material picking claw 100 releases the stuck PCB board; the electrical signal generated by the slot-type photoelectric also makes the three-color lamp flash, thereby realizing an alarm. Finally, when the operator has finished processing the stuck PCB board, by applying a backward thrust to the gripping pill 320 fixed on the cylinder fixing plate 300, the suction block 510 is adsorbed by the magnet 521, and the light shielding sheet 310 is placed in the working position of the slot-type photoelectric, the device can be reset.

[0060] By using a soft connection for adsorption connection of a magnetic mechanism 500 between the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400, and when a material is stuck during the material picking process, the magnetic mechanism 500 is disabled, the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 are separated, and relative sliding between the two is allowed, so that when a product is stuck, excessive material picking pulling force will not act on the product, and from a mechanical point of view, the product is prevented from being damaged by the material picking pulling force, the loss of finished products is reduced, and production safety is maintained; in addition, by The fixing plates 400 are connected by a sliding connection combined with an adsorption connection, and the groove-type photoelectric fixing plate 400 is connected to the power assembly to apply external tension to the entire device. The cylinder fixing plate 300 is fixedly connected to other components of the device such as the clamping claw cylinder 200, thereby forming a structural connection method for the entire device, so that the overall structure of the anti-stuck PCB board material removal device is compact, light and simple, and easy to maintain and operate. In addition, after the material jam occurs and the material jam is manually handled, it only needs to close the cylinder fixing plate 300 and the groove-type photoelectric fixing plate 400. The entire device can be quickly reset by sliding, saving maintenance time; the magnetic mechanism 500 only uses the adsorption effect between magnets for adsorption connection, which plays the role of replacing the pressure sensor, so that the expected effect can be achieved while reducing the cost of the device; by setting a shading sheet 310 on the cylinder fixing plate 300 and a slot-type photoelectric fixing plate 410 on the slot-type photoelectric fixing plate 400, it is determined whether relative sliding occurs between the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 by whether the shading sheet 310 is located at the working position of the slot-type photoelectric fixing plate 410, that is, it is determined whether the device is in a stuck state. Therefore, the method and device can convert the tension signal of the power component into a displacement signal between the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 when the material is stuck, and further convert the displacement signal into an electrical signal of the slot-type photoelectric 410, so that the stuck signal can be electrically output, thereby providing an electrical signal basis for further realizing the alarm function of the device and the locking function of the power component, and can also further expand the function of the device by outputting the electrical signal to the outside, so that the device is widely used and the function can be expanded.

[0062] Step S100: the gripper cylinder 200 drives the material-retrieving gripper 100 to grip the PCB board, and the power assembly applies a pulling force to the slot-shaped photoelectric fixing plate 400, so that the material-retrieving gripper 100 takes the PCB board out of the bin clamp, including:

[0064] (1.2) The clamping cylinder 200 drives the upper material clamping jaw 110 and the lower material clamping jaw 120 to close, so that the material clamping jaw 100 clamps the PCB board;

[0065] (1.3) The power assembly applies a pulling force to the material picking clamp 100 through the slot-shaped photoelectric fixing plate 400, so that the material picking clamp 100 removes the PCB board from the bin clamp.

[0066] Specifically, in the present embodiment, in the initial state of the device, the upper material picking jaw 110 and the lower material picking jaw 120 of the material picking jaw 100 are in a separated state, that is, the material picking jaw 100 is open, and the power component pushes the device as a whole to a suitable material picking position, that is, the PCB board to be picked up is located between the upper material picking jaw 110 and the lower material picking jaw 120. At this time, the jaw cylinder 200 drives the upper material picking jaw 110 and the lower material picking jaw 120 of the material picking jaw 100 to close, so that the material picking jaw 100 clamps the PCB board, and the anti-static engineering plastic baffle 340 limits the PCB board and can isolate static electricity. Then the power component applies a backward pulling force to the material picking jaw 100 through the slot-type photoelectric fixing plate 400 to pick up the material.

[0068] Step S200: When the material is stuck during the material picking process, the magnetic mechanism 500 fails, so that the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 are separated, including:

[0069] (2.1) When the pulling force applied by the power assembly to the cylinder fixing plate 300 is greater than the magnetic force between the suction block 510 and the magnet, it is determined that the material is stuck;

[0070] (2.2) The suction block 510 and the magnet are separated under the action of the pulling force, driving the air slot type photoelectric fixing plate 400 and the cylinder fixing plate 300 to slide relative to each other.

[0071] Specifically, in this embodiment, the power component applies a backward pulling force to the material picking clamp 100 through the slot-shaped photoelectric fixing plate 400. If the material is stuck when the PCB board is extracted backward, the magnetic mechanism 500 fails, that is, the adsorption connection between the suction block 510 and the magnet 521 fails, and the suction block 510 and the magnet 521 separate, driving the cylinder fixing plate 300 and the slot-shaped photoelectric fixing plate 400 to separate. Specifically, when the power component applies a pulling force to the slot-shaped photoelectric fixing plate 400, When the force is greater than the magnetic force between the suction block 510 and the magnet, it is determined that material jamming occurs, and the suction block 510 and the magnet 521 are separated under the action of the pulling force, driving the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 to separate, allowing the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 to slide relative to each other. Preferably, the magnetic force threshold between the suction block 510 and the magnet 521 is 12N, that is, when the pulling force of the power component is greater than 12N, the suction block 510 and the magnet 521 are separated under the action of the pulling force.

[0072] Reference Figure 4 , further, in some embodiments of the present invention, the cylinder fixing plate 300 is provided with a linear rail 330, and the linear rail 330 is slidably connected to the groove-type photoelectric fixing plate 400;

[0073] Step S300: The cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 slide relative to each other, driving the light shielding sheet 310 to leave the slot-type photoelectric working position, including:

[0074] (3.1) The power assembly drives the slot-shaped photoelectric fixing plate 400 to slide on the linear rail 330, so that the cylinder fixing plate 300 and the slot-shaped photoelectric fixing plate 400 slide relative to each other;

[0075] (3.2) The slot-type photoelectric fixing plate 400 drives the shading sheet 310 to separate from the working position of the slot-type photoelectric 410, and the slot-type photoelectric 410 generates an electrical signal.

[0076] Specifically, in this embodiment, the cylinder fixing plate 300 and the slot-type photoelectric fixing plate 400 slide relative to each other along the direction of the linear rail 330, that is, the slot-type photoelectric fixing plate 400 slides backward along the linear rail 330 under the pulling force of the power component, thereby driving the shading sheet 310 to slide backward, so that the shading sheet 310 is separated from the working position of the slot-type photoelectric 410, so that the shading sheet 310 cannot block the photoelectric path in the slot of the slot-type photoelectric 410, and the slot-type photoelectric 410 generates an electrical signal.

[0077] Further, in some embodiments of the present invention, the PCB board material removal device for preventing material jamming further includes: a three-color light, the three-color light is electrically connected to the slot-shaped photoelectric 410; the slot-shaped photoelectric 410 is also electrically connected to the gripper cylinder 200, and the slot-shaped photoelectric 410 is also electrically connected to the power component;

[0078] Step S400: When the slot-shaped photoelectric device 410 detects that the light shielding sheet 310 is separated from the working position of the slot-shaped photoelectric device 410, the PCB board material taking device for preventing material jamming stops working and alarms, including:

[0079] (4.1) When the slot-type photoelectric 410 detects that the shading sheet 310 is out of the working position of the slot-type photoelectric 410, the slot-type photoelectric 410 sends a detection signal to the three-color light, the gripper cylinder 200 and the power assembly;

[0080] (4.2) After receiving the detection signal, the power assembly stops running; the clamping jaw cylinder 200 adjusts the material picking clamping jaw 100 according to the detection signal, so that the material picking clamping jaw 100 releases the PCB board;

[0081] (4.3) After receiving the detection signal, the three-color light flashes.

[0082] Specifically, in the present embodiment, when the shading sheet 310 is separated from the working position of the slot-type photoelectric 410, so that the shading sheet 310 cannot block the photoelectric path in the slot of the slot-type photoelectric 410, the slot-type photoelectric 410 generates an electrical signal, and the anti-jamming PCB board picking device also includes a three-color light, which is electrically connected to the slot-type photoelectric 410; the slot-type photoelectric 410 is also electrically connected to the clamping claw cylinder 200, and the slot-type photoelectric 410 is also electrically connected to the power component; the electrical signal generated by the slot-type photoelectric 410 is output to the power component, the power component is locked and no longer applies tension, thereby stopping the device from running, and at the same time, the electrical signal generated by the slot-type photoelectric causes the clamping claw cylinder 200 to adjust the picking claw 100, and the picking claw 100 releases the stuck PCB board; the electrical signal generated by the slot-type photoelectric also causes the three-color light to flash, thereby realizing an alarm and preventing the device from causing secondary damage to the stuck PCB board.

[0084] Step S500: After the operator processes the stuck PCB board, the anti-stuck PCB board material removal device is reset, including:

[0085] (5.1) The operator applies a thrust to the gripping pill 320 to make the suction block 510 adsorb to the magnet 521 , and places the light shielding sheet 310 in the working position of the slot-shaped photoelectric 410 .

[0086] Specifically, in this embodiment, when the operator has processed the stuck PCB board, a backward thrust is applied to the gripping ball 320 fixed on the cylinder fixing plate 300 to drive the cylinder fixing plate 300 to slide backward along the linear rail 430, so that the suction block 510 is adsorbed by the magnet 521, and the shading sheet 310 is placed in the working position of the slot-type photoelectric 410 to block the photoelectric path of the slot-type photoelectric 410, so that the slot-type photoelectric 410 no longer generates an electrical signal, the power component is unlocked and resumes working, and the three-color light stops flashing, thereby realizing the reset of the device, making the device reset simple.
