[0033] like Figures 1-8 This utility model proposes a circuit board labeling and positioning device.

[0034] In one exemplary embodiment, the circuit board labeling positioning device includes:

[0035] Base plate 1;

[0036] Conveyor 101, mounted on base plate 1, is used to transport circuit board 25;

[0037] The lifting mechanism is set on the base plate 1. The lifting mechanism includes a driver 5 and a material lifting assembly set at the output end of the driver 5. The material lifting assembly can drive the circuit board 25 to move vertically through the driver 5 and disengage from the conveyor 101.

[0038] The labeling mechanism is set on the base plate 1. The labeling mechanism includes a feeder 4 and a robotic arm 2. The robotic arm 2 is used to grab the label from the feeder 4 and affix it to the circuit board 25.

[0039] In this embodiment, the lifting mechanism enables the circuit board 25 to detach from the conveyor 101 and achieve precise positioning. Then, the labeling mechanism performs the labeling operation. The entire process is automated with label feeding and robotic arm 2 labeling. There is no need for manual re-insertion of the circuit board 25 into the labeling machine for labeling. Compared with the prior art, this utility model improves the labeling efficiency of the circuit board 25 and increases the production capacity of the circuit board 25.

[0040] It is worth noting that in this embodiment, each circuit board 25 module transported on the conveyor 101 includes a fixture and multiple circuit boards 25 disposed on the fixture. The fixture has multiple workstations, and the circuit boards 25 are disposed on the workstations. In a specific embodiment, each fixture has eight workstations, which can be used to place eight circuit boards 25 to move synchronously on the conveyor 101. This utility model can be connected to a burning device. After the burning device completes the burning, the circuit boards 25 can be automatically transported to the labeling workstation through the conveyor 101 to achieve automatic transfer without manual transfer, further improving the labeling efficiency.

[0041] It should also be noted that in this embodiment, the feeder 4 can automatically feed labels, and the output end of the robotic arm 2 is equipped with multiple suction heads for picking up labels. The suction head 3 on the robotic arm 2 picks up the labels through a cylinder. The feeder 4 is electrically interconnected with the robotic arm 2. Through a preset program, the robotic arm 2 can identify the labels provided by the feeder 4, pick up multiple labels at once, and then transfer them to a designated place to attach the labels.

[0042] It should also be noted that the suction head 3 in this embodiment adopts a combination of a cylinder and a vacuum valve. The negative pressure formed by the vacuum valve is used to pick up the label and transfer it to the designated position for label affixing.

[0043] In an exemplary embodiment, the top material assembly includes a push plate 6 and a push block 8. The push plate 6 is connected to the output end of the driver 5. The push plate 6 is provided with multiple fixing rods 7. The push block 8 is fixedly connected to the fixing rods 7. The push block 8 is provided with a positioning unit 9. The circuit board 25 has a positioning hole 2501. The positioning unit 9 is detachably connected to the positioning hole 2501.

[0044] In this embodiment, the push plate 6 can drive the push block 8 to rise. The positioning unit 9 on the push block 8 will position the circuit board 25 and lift the circuit board 25 so that the circuit board 25 is removed from the conveyor 101.

[0045] For example, in this embodiment, there are two push blocks 8, located on the left and right sides of the conveyor 101 respectively. The push plate 6 in the top material assembly can rise under the drive of the driver 5. The push plate 6 drives the push blocks 8 on both sides to rise synchronously, so as to provide a stable lifting force and ensure the balance of the circuit board 25 when it rises.

[0046] For example, in this embodiment, the conveyor 101 is provided with a limiting plate 17, which is "L"-shaped and has a limiting part located inside the conveyor 101. In a specific embodiment, the "L"-shaped limiting plate 17 is installed on the conveyors 101 on both sides, and one part of the limiting plate 17 extends into the conveyor 101 and is located above the lifting mechanism. When the lifting mechanism lifts the circuit board 25 together with the fixture, the circuit board 25 or the fixture contacts the limiting part through the limiting action of the limiting part, so that the circuit board 25 can no longer rise, thereby ensuring that the circuit board 25 is accurately positioned and will not shake.

[0047] For example, in this embodiment, the positioning hole 2501 is formed on the circuit board 25, or it can be formed on the fixture. The positioning unit 9 includes a fixing sleeve 901 and a positioning head 902. The fixing sleeve 901 is fixedly connected to the fixing plate. The positioning head 902 is slidably connected to the fixing sleeve 901. A spring 903 is provided between the positioning head 902 and the inner bottom of the fixing sleeve 901. The end of the positioning head 902 is tapered. The positioning head 902 can be inserted into the positioning hole 2501. In this embodiment, the fixing sleeve 901 is mounted on the fixing plate. The fixing sleeve 901 has a cylindrical hole inside. The bottom of the positioning head 902 is cylindrical, and the head is conical. The head can be inserted into the positioning hole 2501. The positioning head 902 lifts the circuit board 25 together with the fixture. After the circuit board 25 is fixed by the limiting plate 17, during the upward movement of the fixing sleeve 901 and the positioning head 902, the positioning head 902 will compress the bottom spring 903 because the circuit board 25 is limited, thus improving the positioning effect and preventing the circuit board 25 from shaking during the labeling process, ensuring accurate labeling. In a specific embodiment, the positioning hole 2501 can be opened on the fixture, or an existing hole on the circuit board 25 can be used.

[0048] In this embodiment, the number of positioning units 9 is six, which is less than or equal to the number of circuit boards 25.

[0049] In an exemplary embodiment, the push block 8 is provided with multiple guide posts 10, and the base plate 1 is provided with guide sleeves 11 corresponding to the guide posts 10 one by one. The guide posts 10 and the guide sleeves 11 are slidably connected.

[0050] In this embodiment, the stability of the top material assembly during vertical movement can be achieved by the sliding cooperation between the guide post 10 on the push block 8 and the guide sleeve 11 on the base plate 1.

[0051] In an exemplary embodiment, a limiting component is also provided on the base plate 1. The limiting component is located on the rear side of the lifting mechanism. The limiting component includes a seat plate 12, a limiting cylinder, and a limiting rod 15. The seat plate 12 is disposed on the base plate 1. The limiting cylinder 13 is disposed at the bottom of the seat plate 12. The output end of the limiting cylinder 13 is provided with a drive plate 14. The limiting rod 15 is disposed on the drive plate 14. The limiting rod 15 can be used to pass through the seat plate 12 and move in the vertical direction.

[0052] For example, by setting a limiting component, the circuit board 25 can be limited in the forward and backward directions of the conveyor belt to ensure that the lifting mechanism can smoothly lift the circuit board 25. In this embodiment, the limiting component includes a base plate 12, a limiting cylinder, and a limiting rod 15. The base plate 12 is set on the base plate 1, the limiting cylinder is set at the bottom of the base plate 12, the output end of the limiting cylinder is provided with a drive plate 14, and the limiting rod 15 is set on the drive plate 14. The limiting rod 15 can pass through the base plate 12 and move in the vertical direction. In a specific embodiment, there are two limiting components, symmetrically arranged on the base plate 1, located on the transmission path of the conveyor 101. When the output end of the limiting cylinder extends, it drives the drive plate 14 to move up and down. The limiting rod 15 mounted on the drive plate 14 moves up and down synchronously. When the drive rod rises, it will block the transmission path of the circuit board 25, preventing the circuit board 25 from continuing to move forward. When the drive rod falls, the circuit board 25 can continue to be conveyed forward.

[0053] It is worth noting that the conveyor 101 is equipped with a positioning detection unit 16, which is electrically connected to the limit cylinder and the driver 5. The positioning detection unit 16 can detect whether the circuit board 25 is in position. When the circuit board 25 is about to be in position, the limit cylinder, which is electrically connected to the positioning detection unit 16, controls the limit rod 15 to rise through the controller, and simultaneously controls the lifting mechanism to lift the circuit board 25 for labeling.

[0054] In an exemplary embodiment, the labeling and positioning device for the circuit board 25 further includes a pushing mechanism, which includes a base 18, a slider 20, and a push rod 24. The base 18 is disposed on the base plate 1, the slider 20 is slidably connected to the base 18, the base 18 is provided with an electric drive unit 19, a lead screw 21 is provided between the output end of the electric drive unit 19 and the slider 20, the lead screw 21 is threadedly connected to the slider 20, and the push rod 24 is rotatably connected to the slider 20.

[0055] In this embodiment, the pusher mechanism can push the labeled circuit board 25 forward into the receiver, avoiding the inability of the circuit board 25 to be fully received into the pusher due to insufficient conveying distance of the conveyor 101. Specifically, after labeling is completed, the circuit board 25 is put back into the conveyor 101 for conveying. The electric drive unit 19 is started, the lead screw 21 rotates, and the slider 20 connected to the lead screw 21 can move back and forth on the base 18 to drive the push rod 24 to move back and forth. The push rod 24 moves along the conveying direction of the conveyor 101 to send the circuit board 25 into the receiver.

[0056] For example, in this embodiment, in order to avoid motion interference between the push rod 24 and the circuit board 25 during the return stroke, after the next batch of circuit boards 25 enters the lifting position of the lifting mechanism, the lifting mechanism lifts the circuit board 25 to leave space at the bottom, the electric drive unit 19 starts, the lead screw 21 rotates in the opposite direction, and the push rod 24 is reset, thereby effectively avoiding collision between the push rod 24 and the circuit board 25 in the labeling process.

[0057] For example, depending on the lifting height of circuit board 25, if the lifting height of circuit board 25 is insufficient, push rod 24 will collide with circuit board 25 during its return stroke. A mechanism capable of rotating push rod 24 can be provided on slider 20 to prevent motion interference between push rod 24 and circuit board 25. Specifically, slider 20 is equipped with a positioning plate 22, and the positioning plate 22 is equipped with a drive motor 23. The output end of drive motor 23 is connected to one end of push rod 24, allowing push rod 24 to rotate axially around the output end of drive motor 23. When push rod 24 needs to return to its original position, drive motor 23 rotates, causing push rod 24 to rotate downwards, preventing collision with circuit board 25 during the return stroke.

[0058] For example, the head of the push rod 24 is provided with an arc-shaped groove so as to be positioned with the circuit board 25 when pushing the material.

[0059] It is worth noting that in this embodiment, the push rod 24 is inclined, and the inclination direction is upward towards the conveying direction of the conveyor 101.

[0060] Specific implementation steps:

[0061] First, under the conveying function of the conveyor 101, the circuit board 25 moves along the conveying direction of the conveyor 101. When the arrival detection unit 16 detects that the circuit board 25 has arrived, the controller controls the conveyor 101 to stop. At the same time, the limit cylinder electrically connected to the arrival detection unit 16 controls the limit rod 15 to rise through the controller. The controller synchronously controls the lifting mechanism to lift the circuit board 25. The positioning head 902 in the lifting mechanism cooperates with the positioning hole 2501 on the circuit board 25 to lift the circuit board 25 as a whole. The circuit board 25 is separated from the conveyor 101. During the upward movement of the fixing sleeve 901 and the positioning head 902, the circuit board 25 is in the vertical direction. The upper part is limited by the limiting plate 17, so the positioning head 902 will compress the bottom spring 903 to improve the positioning effect and prevent the circuit board 25 from shaking during the labeling process, thus ensuring the labeling effect. After the positioning is completed, the robotic arm 2 can move to the designated place to label the circuit board 25. After the labeling is completed, the top material assembly is lowered by the driver 5, and the limiting rod 15 is lowered synchronously. The circuit board 25 comes into contact with the conveyor belt of the conveyor 101. The conveyor belt restarts and transfers the circuit board 25 to the rear. During the transfer, the push rod 24 moves synchronously until the circuit board 25 is pushed completely away from the conveyor 101 and enters the receiver for storage.

[0062] In summary, the lifting mechanism in this utility model enables the circuit board 25 to detach from the conveyor 101 and achieve precise positioning. Then, the labeling mechanism performs the labeling operation. The entire process is automated through label feeding and robotic arm 2 labeling, eliminating the need for manual re-insertion of the circuit board 25 into the labeling machine. This improves the labeling efficiency of the circuit board 25 and also increases its production capacity.
