Abstract
Description
Technical Field
[0001] This invention relates to the field of PCB board processing technology, and in particular to a multifunctional PCB board marking device. Background Technology
[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for the electrical interconnection of these components.
[0003] Rounding corners involves machining the sharp 90-degree right angles of a PCB board into rounded corners of a certain radius through mechanical milling or grinding. The rounded transition can significantly disperse the stress acting on the corner, avoiding stress concentration that could cause the material to crack from the corner or the copper foil or solder mask to peel up.
[0004] Precisely sized and positioned grooves (often called "locating grooves" or "tooling grooves") are milled into the edges of the PCB. These grooves precisely match the locating pins on subsequent SMT placement machines, wave soldering fixtures, test fixtures, and assembly fixtures to ensure that the PCB is fixed in the same position in automated equipment, guaranteeing the accuracy and consistency of assembly and testing.
[0005] When rounding corners and marking grooves on existing PCBs, they need to be placed between the two tool holders. However, since the PCB lacks markings, it may deflect during the setting and conveying process, resulting in deviations during marking and affecting the marking accuracy of the PCB, which in turn affects subsequent processing operations.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] The multifunctional PCB board marking device disclosed in this invention is mainly used in scenarios where the PCB board lacks markings, and therefore may deflect during the setting and conveying process, resulting in deviations during the marking process, affecting the marking accuracy of the PCB board, and consequently affecting subsequent processing operations.
[0022] Reference Figures 1-10 A multifunctional PCB board marking device, comprising: Two guide rail bases 1, with a central plate platform 12 and a central column 15 disposed between the two guide rail bases 1; Two guide rail platforms 6 are respectively set on two guide rail bases 1.

Two chamfering mark machining tool holders 5 are respectively set on two guide rail plates 6; Two central negative pressure platforms 7 are installed on the central column 15. The deflection correction unit 8 is mounted on the central column 15. The deflection correction unit 8 includes an annular guide rail 811, four negative pressure suction cups 805 and two pushers 827. The four negative pressure suction cups 805 are all located above the annular guide rail 811. The label cleaning module 4 is set on one of the horizontal plates 3. The label cleaning module 4 includes a cleaning tube 409 and a fixed turntable 407. Multiple elastic balls 414 are set on the fixed turntable 407.
[0023] Reference Figure 2 and Figures 4-8 In a preferred embodiment, the deflection correction unit 8 further includes: Mounting bracket 801 is mounted on the central column 15. A linear guide rail 802 is mounted on the mounting bracket 801, and a linear lead screw 809 is mounted on the linear guide rail 802. Stepper motor 810 is mounted on linear guide rail 802. The output shaft of stepper motor 810 is connected to one end of linear lead screw 809 via a coupling. Linear lead screw 809 and linear guide rail 802 are provided with the same slider 816. The bracket 825 is mounted on the slider 816, and the annular guide rail 811 is mounted on the bracket 825.
[0024] In this invention, the deflection correction unit 8 further includes: Two arc-shaped block seats 812 are both mounted on an annular guide rail 811. Each arc-shaped block seat 812 is equipped with a fixed bracket 804. Four negative pressure suction cups 805 are respectively mounted on the two fixed brackets 804. Two fixing parts 806 are provided, both of which are mounted on the annular guide rail 811. Each of the two fixing parts 806 is provided with a return spring 807, and one end of each return spring 807 is mounted on a fixed bracket 804.
[0025] In this invention, the deflection correction unit 8 further includes: Two negative pressure pumps 814 are respectively mounted on two fixed brackets 804, and each of the two negative pressure pumps 814 has a negative pressure pipe 815 at its input end. Two connecting chambers 817 are respectively located at the input ends of two negative pressure pipes 815, and the output ends of four negative pressure suction cups 805 are respectively connected to the interior of the two connecting chambers 817. Two fixed sleeves 813 are respectively set on two arc-shaped block seats 812. Two guide holes are opened on each of the two fixed sleeves 813, and limit rods 823 are set inside the four guide holes.
[0026] In this invention, the deflection correction unit 8 further includes: Four connectors 822 are respectively mounted on four limit rods 823; Two central rods 821 are respectively set on four connecting parts 822, and a locking rod 818 is set at the top of each of the two central rods 821. Two anti-slip ring pads 803 are provided on the annular guide rail 811; Two gear plates 820 are respectively mounted on two central rods 821.
[0027] In this invention, the deflection correction unit 8 further includes: Two general-purpose motors 819 are respectively mounted on two fixed sleeves 813. The output shafts of the two general-purpose motors 819 are connected to drive gears 824 through couplings. The two drive gears 824 mesh with two gear plates 820 respectively. An electric actuator 829 is mounted on a bracket 825, and a connecting arc frame 808 is provided at the output end of the electric actuator 829. Two fixed rods 828 are provided on the connecting arc frame 808, and two pushers 827 are provided on the two fixed rods 828 respectively. Each of the two pushers 827 is provided with an inner pad 826.
[0028] Specifically, during the realignment process, the stepper motor 810 operates, driving the linear lead screw 809 to rotate. This causes the linear lead screw 809 to move the slider 816 up and down on the linear guide rail 802. The slider 816 then lifts the support 825, the annular guide rail 811, the arc-shaped block seat 812, and the negative pressure suction cup 805 until the height of the negative pressure suction cup 805 is slightly higher than the central negative pressure platform 7. At this point, the PCB board is placed on the negative pressure suction cup 805, and the negative pressure pump 814 operates. The gas inside the connecting chamber 817 is discharged through the negative pressure pipe 815, so that the inside of the connecting chamber 817 is in a negative pressure state, which allows the negative pressure suction cup 805 to adsorb and fix the PCB board. At this time, the electric push rod 829 drives the connecting arc frame 808 to move towards one side of the PCB board, and causes the pusher 827 to drive the inner layer pad 826 to contact one side edge of the PCB board and push it to move. At this time, as the pusher arc block seat 812 can move on the annular guide rail 811, the reset spring 807 is deformed until the PCB board is straightened. After correction, the general motor 819 runs, driving the drive gear 824 to rotate. Since the drive gear 824 meshes with the gear plate 820, it can drive the gear plate 820 and the central rod 821 to rise and fall, and further cause the central rod 821 to drive the locking rod 818 to rise until the locking rod 818 contacts the anti-slip ring pad 803 below the annular guide to lock and fix the position of the arc block seat 812. Then the stepper motor 810 runs in reverse, causing the PCB board to fall and contact the central negative pressure platform 7. At this time, the central negative pressure platform 7 adsorbs and fixes the PCB board, while the negative pressure suction cup 805 separates from the PCB board. Then the device resets to complete the deflection correction operation of the PCB board. In specific application scenarios, the deflection correction unit 8 is suitable for the PCB board marking process. That is, the deflection correction unit 8 can correct the deflection angle of the PCB board during the marking operation. After correction, the device can lock and fix the posture of the PCB board so that the PCB board can maintain the corrected state on the central negative pressure stage 7. This ensures that the posture of the PCB board itself and the posture of the device are parallel during processing, thereby avoiding deviations in the marking process of the PCB board, increasing the marking accuracy of the PCB board, ensuring the accuracy of subsequent processing steps, and improving the performance of the device. It should be noted that after the deflection correction adjustment, the device can reset the negative pressure suction cup 805 and the arc block seat 812 through the reset spring 807, so as to facilitate the subsequent PCB board marking deflection correction operation.
[0029] Reference Figure 1 , Figure 2 , Figure 9 and Figure 10 In a preferred embodiment, the label cleaning module 4 further includes: Mounting component 401 is mounted on one of the horizontal plates 3. An electric telescopic rod 402 is mounted on the mounting component 401. A connecting plate frame 403 is provided at the output end of the electric telescopic rod 402. The tube passage compartment 413 is mounted on the connecting plate frame 403, and the cleaning tube compartment 409 is mounted on the tube passage compartment 413. The cleaning tube compartment 409 has multiple cleaning holes 415.
[0030] In this invention, the label cleaning module 4 further includes: A rotating roller frame 408 is mounted on a tube chamber 413, a fixed turntable 407 is mounted on the rotating roller frame 408, and a gear ring 406 is mounted on the rotating roller frame 408. Servo motor 404 is mounted on connecting plate frame 403. The output shaft of servo motor 404 is connected to transmission gear 405 through a coupling. Transmission gear 405 meshes with gear ring 406.
[0031] In this invention, the label cleaning module 4 further includes: A connecting pipe 412 is provided on the pipe compartment 413, and a dust filter bag compartment 411 is provided at the output end of the connecting pipe 412. Cleaning pump 410 is installed on the dust filter bag chamber 411.
[0032] Specifically, after the marking process, the PCB board will be discharged and pass under the cleaning tube 409. At this time, the cleaning pump 410 runs and discharges the gas inside the dust filter bag 411 to make it negative pressure. Furthermore, through the connecting pipe 412, both the passage tube 413 and the cleaning tube 409 are in a negative pressure state to clean the debris or dust attached to the surface of the PCB board. During the cleaning process, the servo motor 404 drives the transmission gear 405 to rotate. Since the transmission gear 405 meshes with the gear ring 406, it drives the gear ring 406 and the rotating roller frame 408 to rotate. Furthermore, the rotating roller frame 408 drives the fixed turntable 407 and the elastic ball 414 to rotate. Since the elastic ball 414 has elastic micro-contact with the PCB board, it can cause the PCB board to vibrate slightly during the cleaning process until the PCB board is cleaned. In specific application scenarios, the label cleaning module 4 is suitable for the label processing and cleaning process of PCB boards. That is, when the label cleaning module 4 is used, it can clean the debris and dust generated during the label processing of PCB boards, so as to prevent the debris and dust from adhering to the PCB board after the label processing, thereby preventing the debris or dust from reducing the adhesion of the solder resist ink, ensuring the subsequent processing quality of the PCB board, and thus improving the use effect of the device. It should be noted that during cleaning, the device can generate continuous micro-elastic impacts with the PCB board through the elastic ball 414, thereby causing the PCB board to vibrate slightly, thus increasing the cleaning effect of the device.
[0033] Reference Figure 1 , Figure 3 and Figure 4In a preferred embodiment, two lower pressure plates 9 are respectively provided on the four mounting columns 2. The two lower pressure plates 9 and the central column 15 are each provided with a discharge lifting cylinder 14. The two lower pressure plates 9 and the central plate 12 are provided with a belt feeding mechanism 13. The output ends of the three discharge lifting cylinders 14 are all provided on the belt feeding mechanism 13. Multiple upper pressure cylinders 10 are provided on the two horizontal plates 3. Each of the multiple upper pressure cylinders 10 is provided with an upper pressure plate 11. The multiple upper pressure plates 11 are respectively located above the two lower pressure plates 9.
[0034] Device: The upper pressure plate 11, the upper pressure cylinder 10, and the lower pressure plate 9 can fix the PCB board during use; The belt feeding mechanism 13 and the discharge lifting cylinder 14 can be used together to discharge the PCB board after it has been labeled.
[0035] Working principle: During the realignment process, the stepper motor 810 operates, driving the linear lead screw 809 to rotate. This causes the linear lead screw 809 to move the slider 816 up and down on the linear guide rail 802. The slider 816 then lifts the support 825, the annular guide rail 811, the arc-shaped block seat 812, and the negative pressure suction cup 805 until the height of the negative pressure suction cup 805 is slightly higher than the central negative pressure platform 7. At this point, the PCB board is placed on the negative pressure suction cup 805, and the negative pressure pump 814 operates. The negative pressure pump 814 then... The pressure tube 815 discharges the gas inside the connecting chamber 817, so that the inside of the connecting chamber 817 is in a negative pressure state, which causes the negative pressure suction cup 805 to adsorb and fix the PCB board. At this time, the electric push rod 829 drives the connecting arc frame 808 to move towards one side of the PCB board, and causes the pusher 827 to drive the inner layer pad 826 to contact one side edge of the PCB board and push it to move. At this time, as the pusher arc block seat 812 can move on the annular guide rail 811, the reset spring 807 deforms until the PCB board is straightened. After correction, the general motor 819 runs, driving the drive gear 824 to rotate. Since the drive gear 824 meshes with the gear plate 820, it can drive the gear plate 820 and the central rod 821 to rise and fall, and further cause the central rod 821 to drive the locking rod 818 to rise until the locking rod 818 contacts the anti-slip ring pad 803 below the annular guide to lock and fix the position of the arc block seat 812. Then the stepper motor 810 runs in reverse, causing the PCB board to fall and contact the central negative pressure platform 7. At this time, the central negative pressure platform 7 adsorbs and fixes the PCB board, while the negative pressure suction cup 805 separates from the PCB board. Then the device resets to complete the deflection correction operation of the PCB board. After the marking process, the PCB board will be discharged and pass under the cleaning tube 409. At this time, the cleaning pump 410 runs and discharges the gas inside the dust filter bag 411 to make it negative pressure. Furthermore, through the connecting pipe 412, both the passage tube 413 and the cleaning tube 409 are in a negative pressure state to clean the debris or dust attached to the surface of the PCB board. During the cleaning process, the servo motor 404 drives the transmission gear 405 to rotate. Since the transmission gear 405 meshes with the gear ring 406, it drives the gear ring 406 and the rotating roller frame 408 to rotate. Furthermore, the rotating roller frame 408 drives the fixed turntable 407 and the elastic ball 414 to rotate. Since the elastic ball 414 has elastic micro-contact with the PCB board, it can cause the PCB board to vibrate slightly during the cleaning process until the PCB board cleaning is completed.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
