Description

Technical Field

[0001] The present application relates to the field of clamp technology, and specifically to a PCB board tray material picking clamp mechanism. Background Art

[0002] A PCB tray is a device used to hold and support printed circuit boards (PCBs). PCB retrieving refers to the process of removing the required components from the tray or box where they are stored and then accurately placing them on the PCB during the electronics manufacturing process.

[0003] The existing technology cannot achieve mechanical fixed-position grabbing due to the large random gap between the material box and the carrier. The existing method uses manual labor to remove the materials from the carrier of the material box. The disadvantages are high labor costs and the risk of misplacement.

[0004] On the basis of this existing technology, the carrier boards on which the PCB workpieces are placed are regularly stacked to achieve mechanical fixed position grabbing of the PCB boards. However, since the clamping mechanism is not adaptable to the PCB carrier boards, manual intervention is still required for semi-automation. In view of the problem that the above-mentioned clamping mechanism requires precise PCB carrier board position and is not suitable for the carrier boards, a PCB board carrier tray material picking clamping mechanism is proposed to solve the problem. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a PCB board tray material picking clamp mechanism, which has the advantages of being able to automatically pick up materials and stack the trays without human intervention, and can locate and grasp without precise positioning.

[0006] To achieve the above objectives, the present application provides the following technical solutions: a PCB board tray material removal clamping mechanism, comprising a mounting frame, a flange tube is fixedly mounted on the top of the mounting frame, and a clamping structure is provided on the bottom of the mounting frame;

[0007] The clamping mechanism includes a claw provided at the bottom of the mounting frame and an actuator for pushing the claw, a traction block is fixedly installed on the top of the claw, and a swing block is movably connected to the power end of the actuator;

[0008] A visual guidance positioning device is also provided on the front of the mounting frame, and a vacuum suction cup is also provided on the side wall of the mounting frame.

[0009] Furthermore, a mounting rod is provided at the bottom of the mounting frame, wherein the mounting rod includes two upper and lower rods, one of which is fixedly mounted relative to the mounting frame, and the other is detachably plugged into the mounting frame.

[0010] Furthermore, an extension claw is connected below the latch claw, and a connecting plate for sliding extension is fixedly mounted on opposite side surfaces of the extension claw and the latch claw.

[0011] Furthermore, a trapezoidal groove is provided on the inner side wall of the extending claw.

[0012] Furthermore, a through hole is formed on the connecting plate, and the mounting rod is inserted into the through hole.

[0013] Furthermore, a slide cylinder is fixedly mounted on the side wall of the mounting frame, an arch frame is fixedly mounted on the power end of the slide cylinder, and vacuum suction cups are fixedly mounted on both ends of the arch frame by bolts.

[0014] Furthermore, a vacuum suction cup electronic pressure regulator connected to the vacuum suction cup is also installed on the mounting frame, and a sensor is also provided on the front of the mounting frame, and the sensor is specifically a position status monitoring sensor.

[0015] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0016] The PCB tray picking claw mechanism is equipped with both claws and vacuum suction cups on a mounting frame, and a visual guidance positioning device is provided to guide and position the mounting frame relative to the PCB board, thereby being able to adapt to the random gaps between the material box and the tray. At the same time, the vacuum suction cups are installed by providing a slide cylinder and an arch frame, so that the PCB board and the PCB tray can be grasped, thereby improving the practicality of the device, realizing unmanned production operations, reducing labor intensity and burden, and avoiding misplacement and damage to products.

[0025] Preferably, the clamping mechanism includes a claw 4 provided at the bottom of the mounting frame 1 and an actuator 7 for pushing the claw 4, wherein the actuator 7 is an electric push rod for pushing the claw 4 to approach and grasp the PCB board.

[0026] In this embodiment, a mounting rod 3 is further provided at the bottom of the mounting frame 1, wherein the mounting rod 3 includes two upper and lower rods, one mounting rod 3 is fixedly installed relative to the mounting frame 1, and the other mounting rod 3 is detachably plugged into the mounting frame 1, and the claw 4 has a hole for the mounting rod 3 to pass through, so that the claw 4 can slide close to the mounting rod 3 for clamping.

[0027] In this embodiment, an extension claw 41 is further connected to the lower side of the latch claw 4 , and a connecting plate 43 for sliding extension is fixedly mounted on the opposite side surfaces of the extension claw 41 and the latch claw 4 .

[0028] It should be noted that a trapezoidal groove 42 is provided on the inner side wall of the extending claw 41 . The provision of the groove 42 can improve the contact stability of the extending claw 41 relative to the edge of the PCB board.

[0029] In this embodiment, a through hole 44 is formed on the connecting plate 43 , and the mounting rod 3 is inserted into the through hole 44 to limit the sliding extension position of the extending claw 41 relative to the locking claw 4 .

[0030] It should be noted that a traction block 5 is fixedly mounted on the top of the pawl 4 , and a swing block 6 is movably connected to the power end of the actuator 7 .

[0031] Specifically, the power end of the actuator 7 is slidably connected to the swing block 6, and the swing block 6 is rotatably connected to the mounting frame 1. The actuator 7 pushes the swing block 6, so that the swing block 6 swings relative to the mounting frame 1 to push the traction block 5.

[0032] In this embodiment, a visual guidance positioning device 13 is also provided on the front of the mounting frame 1 for accurately positioning the workpiece and guiding the gripper robot to grasp it accurately; a barcode scanner 14 is also fixedly installed inside the mounting frame 1 through an L-shaped bending plate.

[0033] In this embodiment, a slide cylinder 8 is fixedly installed on the side wall of the mounting frame 1, an arch frame 9 is fixedly installed on the power end of the slide cylinder 8, and vacuum suction cups 10 are bolted to both ends of the arch frame 9 for grabbing the PCB board carrier.

[0034] It should be noted that the slide cylinders 8 are distributed on both sides of the mounting frame 1 , there are four vacuum suction cups 10 , and the vacuum suction cups 10 extend to the outside of the claws 4 to grab the PCB board tray to avoid the claws 4 .

[0037] The working principle of the above embodiment is:

[0038] The vision-guided positioning device 13 is used to guide the robotic arm to control the mounting frame 1 to move above the PCB board carrier. The robotic arm moves the mounting frame 1 to a position above the PCB board. At this time, the vision-guided positioning system and the clamping mechanism control the assembly information transmission interaction to control the actuator 7. The actuator 7 drives the swing block 6 on the power end to rotate relative to the mounting frame 1. The swing block 6 pushes the claw 4 on the mounting rod 3 during the swing. The claw 4 approaches along the mounting rod 3 and engages with the two sides of the PCB board through the groove 42 to grab the PCB board for transportation. After the PCB board is continuously transported from the carrier, the vision-guided positioning device 13 is used again to guide the mounting frame 1 to move above the carrier. The arch frame 9 on the power end is pushed to move by controlling the slide cylinder 8, so that the four vacuum suction cups 10 move down to the outer position of the claw 4. Then the vacuum suction cup electronic pressure regulating meter 11 controls the vacuum suction cup 10 to grab the carrier to complete the automatic grabbing and stacking of the PCB board.
