The recycling mechanism 4 is at the rear end of the processing platform 1, responsible for recycling the empty pallet after the pallet is used up. The conveying assembly 3 is at the top of the processing platform 1 close to the feeding mechanism 2, and cooperates with the feeding mechanism 2 to realize the precise positioning and movement of the pallet, ensuring that the pallet accurately reaches the bottom of the suction arm 9. The various components of the entire device work together to realize automatic and efficient feeding of the circuit board.

[0041] Please see attached Figure 3 The feeding mechanism 2 includes a protective shell 201, which is installed at the bottom of the processing platform 1. A motor 202 is installed on the middle side of the protective shell 201. Bevel gear 1 203 is installed on the left and right sides of the motor 202. Bevel gear 2 204 is rotated on the top of the left and right sides of the protective shell 201. Bevel gear 1 203 is meshed with bevel gear 204. A threaded rod 205 is fixed inside the bevel gear 204.

The outer periphery of the shell 206 is threadedly connected to a fixing component 6.

[0042] In the present invention, the protective shell 201 is installed at the bottom of the processing platform 1 to protect the internal motor 202 and other components, and at the same time provide rotation support for the bevel gear 2 204 and the like.

When the motor 202 rotates, it drives the bevel gear 1 203 to rotate, and then the bevel gear 204 rotates, and the threaded rod 205 fixed inside the bevel gear 204 rotates accordingly, realizing power transmission. The end of the threaded rod 205 away from the bevel gear 204 rotates in the shell 206, and the limit rod 207 inside the shell 206 provides guidance and limitation for the movement of the movable plate 601, ensuring that the movable plate 601 can move stably vertically when the threaded rod 205 rotates. The fixing component 6 connected by threads on the outer periphery of the shell 206 is used to fix the pallet, wherein the movable plate 601 is connected to the threaded rod 205 by threads and moves when the threaded rod 205 rotates, and the electric push rod 202 drives the fixed plate 603 to fix the pallet.

[0043] Please see attached Figure 7 - Attachment Figure 8 The correcting mechanism 7 includes an electric push rod 701, which is installed inside the suction arm 9. One end of the electric push rod 701 is fixedly connected to a trapezoidal block 702. The front and rear sides of the trapezoidal block 702 are slidably connected to trapezoidal blocks 703. A limiting plate 704 is fixed to the top of the trapezoidal block 703. The limiting plate 704 is slidably connected to the inside of the suction arm 9. A correcting claw 705 is fixed on the side of the trapezoidal block 703 away from the limiting plate 704. Limiting components 8 are provided on the front and rear sides of the trapezoidal block 702.

[0044] In the present invention, an electric push rod 701 is installed inside the suction arm 9 to provide power. A trapezoidal block 702 fixedly connected at one end thereof moves under the push of the electric push rod 701. Trapezoidal blocks 703 slidably connected on the front and rear sides of the trapezoidal block 702 will move toward each other when the trapezoidal block 702 moves. The trapezoidal block 702 is an isosceles trapezoid, while the trapezoidal block 703 is a right-angled trapezoid. The limiting plate 704 fixed on the top of the trapezoidal block 703 slides inside the suction arm 9 to ensure that the movement of the trapezoidal block 703 is stable. The correcting claw 705 on the side of the trapezoidal block 703 away from the limiting plate 704 moves with the trapezoidal block 703 to correct the position of the sucked circuit board, ensuring that the circuit board maintains the correct position and posture during the suction process. The entire correcting mechanism 7 realizes the circuit board position correction function through the cooperation of these components.

[0045] Please see attached Fig.10 The recovery mechanism 4 includes a cylinder 401, which is installed on the side of the rear end of the processing platform 1 close to the suction arm 9. A placement component 5 is provided at the bottom of the rear side of the processing platform 1. A receiving plate 402 is fixed to the end of the cylinder 401 close to the suction arm 9, and a cross bar 403 is fixed inside the receiving plate 402. The outer periphery of the cross bar 403 is slidably connected to an electric slider 404. A clamping block 405 is fixed to the side of the two electric sliders 404 close to the suction arm 9.

[0046] In the present invention, a cylinder 401 is installed on one side of the rear end of the processing platform 1 close to the suction arm 9, as a driving component for recycling an empty pallet. When the circuit boards in the pallet are used up and need to be recycled, the cylinder 401 is started, and its piston rod extends to push the accommodating plate 402 fixed at one end to move forward, thereby driving the cross bar 403 fixed inside the accommodating plate 402 and the electric slider 404 and the clamping block 405 slidingly connected to the outer periphery of the cross bar 403 to move forward as a whole, so that the clamping block 405 reaches the outer periphery of the pallet, and then the electric slider 404 slides on the cross bar 403, respectively driving the two clamping blocks 405 to move toward the pallet until the pallet is tightly clamped, and then the cylinder 401 is started again, driving the clamping block 405 and the pallet to move backward, and moving the used pallet to the placement component 5 area at the bottom of the rear side of the processing platform 1, completing the pallet recycling operation, and cooperating with the placement component 5 to achieve orderly management of the empty pallet.

[0047] Please see attached Figure 6 The conveying assembly 3 includes a second cylinder 301, which is installed on the top of the processing platform 1 close to the feeding mechanism 2. A second cross bar 302 is fixed to the end of the second cylinder 301 close to the suction arm 9, and two connecting rods 303 are fixed to the side of the second cross bar 302 away from the second cylinder 301. A sliding rod 304 is fixed inside the second cross bar 302, and an electric slider 305 is slid on the outer periphery of the sliding rod 304. A connecting block 306 is fixed on the top of the two electric sliders 305, and a splint 307 is fixed to the side of the connecting block 306 away from the electric slider 305.

[0048] In the present invention, the second cylinder 301 is installed on the top of the processing platform 1 near the feeding mechanism 2. When working, the second cylinder 301 is started, and its piston rod pushes the second crossbar 302 fixed on one end of the suction arm 9 to move, and the two connecting rods 303 fixed on the side of the second crossbar 302 away from the second cylinder 301 move together to achieve preliminary position adjustment. The sliding rod 304 fixed inside the second crossbar 302 provides a sliding track for the second electric slider 305. The second electric slider 305 slides on the periphery of the sliding rod 304 to accurately adjust the position. The connecting block 306 fixed on the top of the two second electric sliders 305 and the clamping plate 307 fixed on the side of the connecting block 306 away from the second electric slider 305, driven by the second electric slider 305, the clamping plate 307 can accurately approach or move away from the pallet, and finally achieve the clamping and accurate transportation of the pallet, and move the pallet from the initial position to the bottom of the suction arm 9, so as to prepare for the subsequent suction operation and ensure the continuity and accuracy of the entire feeding process.

[0049] Please see attached Figure 5The fixing assembly 6 includes a movable plate 601, which is threadedly connected to the outer periphery of the threaded rod 205. An electric push rod 602 is provided in the middle of the movable plate 601. A fixed plate 603 is fixed to the side of the electric push rod 602 away from the movable plate 601. The side of the movable plate 601 away from the threaded rod 205 slides on the outer periphery of the limiting rod 207, and the side of the movable plate 601 away from the fixed plate 603 is slidably connected to the inside of the limiting rod 207.

[0050] In the present invention, the movable plate 601 is threadedly connected to the outer periphery of the threaded rod 205. When the threaded rod 205 rotates driven by the bevel gear 204, the movable plate 601 will move vertically along the threaded rod 205 due to the threaded transmission, thereby adjusting the position so that the movable plate 601 is always located at the outer periphery of the bottom tray. The electric push rod 2 602 arranged in the middle of the movable plate 601 is used to provide power. When the movable plate 601 moves to a suitable position, the electric push rod 2 602 is started, and the fixed plate 603 fixed on the side away from the movable plate 601 will move toward the tray under the push of the electric push rod 2 602, and finally come into close contact with the tray, thereby fixing the position of the tray and preventing the tray from being displaced in subsequent operations.

[0051] Please see attached Fig.11 The placement component 5 includes a plurality of placement plates 501, which are evenly distributed in a rectangular shape and installed at the rear bottom of the processing platform 1. A guide rail 502 is fixed on the periphery of the placement plate 501, a slide plate 503 is slidable on the periphery of the guide rail 502, and a positioning plate 504 is movable on one side of the slide plate 503 close to the placement plate 501.

[0052] In the present invention, a plurality of rectangular evenly distributed placement plates 501 are installed at the bottom rear side of the processing platform 1, providing a special storage area for the recovered empty pallets, and its reasonable layout can realize the orderly placement of a plurality of pallets, which is convenient for management and reuse, and the guide rail 502 fixed on the outer periphery of the placement plate 501 provides a precise track for the sliding of the slide plate 503, ensuring that the slide plate 503 can move stably and smoothly in the vertical direction, and the slide plate 503 is close to the positioning plate 504 movable on one side of the placement plate 501. After the pallet is placed in the placement plate 501 area by the recycling mechanism 4, the positioning plate 504 will contact the pallet and exert a certain pressure on the pallet as the slide plate 503 slides down along the guide rail 502, so that the pallet can be neatly arranged on the placement plate 501, avoiding the pallets from being placed in a disorderly manner, realizing the arrangement and positioning of the pallets, keeping the working area clean and orderly, further optimizing the overall work process, improving the convenience and standardization of production management, and helping to improve production efficiency.

[0053] Please see attached Fig. 9The limiting assembly 8 includes a limiting block 801, which is fixed on one side of the trapezoidal block 1 702. A limiting groove 802 is provided inside the trapezoidal block 2 703, and the limiting block 801 slides inside the limiting groove 802.

[0054] In the present invention, the limit block 801 cooperates with the limit groove 802 opened inside the trapezoidal block 2 703. When the electric push rod 1 701 pushes the trapezoidal block 1 702 to move, the limit block 801 will slide inside the limit groove 802, thereby exerting a force on the trapezoidal block 2 703 to move the trapezoidal block 2 703.

[0055] The automatic circuit board feeding method adopts the above-mentioned automatic circuit board feeding device, and comprises the following steps:

[0056] S1. Place the tray with the circuit board on the left side of the processing platform 1, start the motor 202, adjust the position of the movable plate 601 through the bevel gear transmission, the electric push rod 2 602 drives the fixed plate 603 to fix the tray, and the cylinder 2 301 cooperates to move the tray under the suction arm 9.

[0057] S2, the suction arm 9 is started, the suction plate 12 sucks the circuit board, and at the same time the electric push rod 1 701 pushes the trapezoidal block 1 702, so that the trapezoidal block 2 703 drives the deviation correction claw 705 to initially correct the position of the circuit board.

[0058] S3. When the suction arm 9 carries the circuit board through the detection light 10, a secondary deviation correction is performed to ensure accurate positioning. At the same time, the detection light 10 performs visual inspection on the circuit board.

[0059] S4. After the detection is completed, the suction arm 9 accurately places the circuit board in the installation mold 11.

[0060] S5, the cylinder 401 makes the clamp block 405 clamp the pallet and move it to the placement plate 501 area, the slide plate 503 slides along the guide rail 502, and the positioning plate 504 arranges the pallet for placement.

[0061] Working principle: When using the automatic circuit board loading device, first, the tray with the circuit board must be accurately placed at a specific position on the top left side of the processing platform 1, and then the motor 202 is started. When the motor 202 is running, its output shaft drives the bevel gears 203 on the left and right sides to rotate synchronously. Since the bevel gear 203 and the bevel gear 204 are meshed with each other, the rotation of the bevel gear 203 will cause the bevel gear 204 to rotate accordingly, and the threaded rod 205 fixed inside the bevel gear 204 will also rotate together. During the rotation of the threaded rod 205, the movable plate 601 threadedly connected thereto will move vertically due to the principle of threaded transmission, thereby realizing the synchronous movement of the movable plates 601 on the left and right sides of the tray. When the movable plate 601 moves to the appropriate position, the electric push rod 2 602 inside the movable plate 601 is started, and the electric push rod 2 602 extends to push the fixed plate 603 toward the tray until the fixed plate 603 is in close contact with the tray, thereby realizing the initial fixation of the tray position.

[0062] Then, the second cylinder 301 is started, and the piston rod of the second cylinder 301 extends outward, pushing the second crossbar 302 to move in the direction close to the pallet. At this time, the multiple clamping plates 307 fixed on the second crossbar 302 will also move together, and then the second electric slider 305 on the periphery of the slide bar 304 is started, and the second electric slider 305 slides on the slide bar 304, and drives the connecting block 306 and the clamping plate 307 to move further in the direction of the pallet. When the clamping plate 307 contacts the bottom pallet, the second cylinder 301 is started again, and the second cylinder 301 continues to push the second crossbar 302, thereby driving the pallet to move to the bottom of the suction arm 9, so as to prepare for the suction operation;

[0063] Then, the suction arm 9 is started, and the suction plate 12 at the bottom of the suction arm 9 generates suction to suck the circuit board on the tray. While sucking the material, the electric push rod 1 701 is started, and the piston rod of the electric push rod 1 701 extends to push the trapezoidal block 1 702 to move forward. When the trapezoidal block 1 702 moves, the limit blocks 801 on its front and rear sides will slide in the limit grooves 802 opened inside the trapezoidal block 2 703, thereby limiting the movement direction of the trapezoidal block 2 703, so that the two trapezoidal blocks 2 703 can only move towards each other, and the limit plate 704 fixed on the top of the trapezoidal block 2 703 slides inside the suction arm 9 to ensure the stability of the movement of the trapezoidal block 2 703, and the deviation correction claw 705 fixed on the side of the trapezoidal block 2 703 away from the limit plate 704 will move along with the ladder. The second shape block 703 moves toward the direction of the suction plate 12, and performs a correction operation on the sucked circuit board to ensure that the circuit board maintains the correct position and posture during the suction process. After the correction is completed, the suction arm 9 moves to the left along the processing platform 1. When the suction arm 9 moves to the top of the detection lamp 10, the circuit board will enter the detection lamp 10 with the movement of the suction arm 9. The detection lamp 10 performs a visual inspection on the circuit board to detect whether the circuit board has defects or other problems. After the inspection is completed, another suction arm 9 is started, and the suction arm 9 sucks the circuit board in the detection lamp 10. Then, through the precise control of the suction arm 9, the circuit board is placed in the installation mold 11, completing the feeding operation of the circuit board, and preparing for subsequent processing or assembly processes;

[0064] When all the circuit boards in the tray are used up, the cylinder 401 is started, and the piston rod of the cylinder 401 extends to push the receiving plate 402 forward, thereby driving the cross bar 403 fixed on the receiving plate 402 and the electric slider 404 and the clamping block 405 on the periphery of the cross bar 403 to move forward as a whole, so that the two clamping blocks 405 move to the periphery of the tray, and then the electric slider 404 on the periphery of the cross bar 403 is started, and the electric slider 404 slides on the cross bar 403, respectively driving the two clamping blocks 405 to move toward the tray direction , until the clamp block 405 tightly clamps the pallet, and then the cylinder 401 is started again, driving the clamp block 405 and the pallet to move backward, and moving the used pallet to the top of the placement plate 501. After the pallet moves to the top of multiple placement plates 501, the slide plate 503 is started, and the slide plate 503 slides downward along the guide rail 502. At this time, the movable positioning plate 504 on the slide plate 503 will contact the pallet, and as the slide plate 503 slides down, a certain pressure is applied to the pallet, so that the pallet can be neatly placed, which is convenient for the subsequent management and reuse of the pallet.
