Technical Field
[0001] This invention belongs to the field of printed circuit board manufacturing technology, specifically relating to a rotatable disassembly device for printed circuit boards. Background Technology
[0002] Circuit boards are important electronic components, serving as the support for electronic components and providing electrical connections. Modern circuit boards primarily consist of circuitry and schematics. The circuitry acts as a means of conduction between components, and a large copper surface is designed separately as a ground and power layer. The circuitry and schematics are fabricated simultaneously. Circuit boards are mainly used to mount components and are applied in various fields, such as computers and mobile phones. After the circuit boards are laminated, they need to be disassembled.
[0003] Utility model patent application CN214757116U discloses a steerable board removal device for printed circuit boards (PCBs), including a removal platform. A steering platform is mounted near the bottom of the front surface of the removal platform, a controller is mounted near the top of the left side surface of the removal platform, and upright plates are mounted on both sides of the upper surface of the removal platform. A top plate is mounted near the top between a group of upright plates. A third hydraulic cylinder, a motor, a suction fan, and a suction cup are installed inside the removal platform. In the aforementioned application, the device requires the motor to continuously change the orientation of the PCB during removal, which can easily cause the PCB to shift position during rotation. Furthermore, localized temperature changes during processing can easily deform the PCB, hindering the removal process. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a rotatable board removal device for printed circuit boards, solving the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention provides a steerable board removal device for printed circuit boards, including a support foot, a processing chamber fixedly connected to the top of the support foot, a control panel fixedly connected to the front side of the processing chamber, a drill bit position adjustment device movably connected to the top of the processing chamber, a board removal drill bit fixedly connected to the bottom of the drill bit position adjustment device, a feeding conveyor belt movably connected to the left side of the processing chamber, and a steering support device movably connected inside the processing chamber. The steering support device has multiple fixed plates 1 fixedly connected to its front and rear surfaces. A rotating shaft 1 is movably connected between every two fixed plates 1. A motor is fixedly connected to the left side of each rotating shaft 1. An electric locking device is fixedly connected to the outer left end of each rotating shaft 1. An L-shaped positioning plate 1 is fixedly connected to the outer center of each rotating shaft 1. A bevel gear 1 is fixedly connected to the right side of each rotating shaft 1. The steering support device also has multiple fixed plates 2 fixedly connected to its left and right surfaces. A rotating shaft 2 is movably connected between every two fixed plates 2. A bevel gear 2 is fixedly connected to the front side of each rotating shaft 2. Engaging with bevel gear two, an L-shaped positioning plate two is fixedly connected to the outer center of the rotating shaft two, a pulley one is fixedly connected to the outer right end of the rotating shaft one, a movable groove one is opened inside the steering support device, a rotating shaft three is movably connected inside the movable groove one, a pulley two is fixedly connected to the outer side of the rotating shaft three, a belt is movably connected to the outer sides of the pulley one and pulley two, a gear one is fixedly connected to the outer side of the rotating shaft three, a lifting rack is movably connected inside the movable groove one, the lifting rack meshes with the gear one, and a lifting bar is fixedly connected to the top of the lifting rack. The system is equipped with L-shaped positioning plate one, L-shaped positioning plate two, and a lifting rack. When the equipment begins the plate disassembly process, the motor is started, and in conjunction with shaft one, bevel gear one, bevel gear two, pulley one, belt, pulley two, shaft three, and gear one, L-shaped positioning plate one and L-shaped positioning plate two are rotated to a vertical position. This allows the circuit board to be automatically centered and fixed on the steering support equipment, preventing the circuit board from shifting position during rotation. After processing is completed, the lifting rack automatically moves the circuit board upwards for easy unloading.
[0006] Furthermore, a circuit board is placed on top of the steering support device, and the inner surfaces of the L-shaped positioning plate one and the L-shaped positioning plate two are in contact with the surrounding surfaces of the circuit board.
[0007] Furthermore, a receiving bin is provided inside the processing chamber, and a steering motor is fixedly connected to the bottom of the steering support device.
[0008] Furthermore, the width of the first movable groove is greater than the width of the belt, and the L-shaped positioning plate second is internally connected with an anti-deformation component.
[0009] Furthermore, the anti-deformation component includes a fixed block, a contact plate, a spring, a first groove, a slider, a rack, a second gear, a fourth shaft, a third fixed plate, a bracket, a second movable groove, and an anti-deformation plate. Fixed blocks are fixedly connected to both sides of the steering support device. A first groove is formed inside the second L-shaped positioning plate. Multiple sliders are movably connected inside the first groove. A rack is fixedly connected to the inner side of each slider. A contact plate is fixedly connected to one end of the rack near the center of the circuit board. A spring is fixedly connected between the contact plate and the second L-shaped positioning plate. Multiple third fixed plates are fixedly connected to the outer surface of the second L-shaped positioning plate. A fourth shaft is movably connected inside every two third fixed plates. A second gear is fixedly connected to the left side of the fourth shaft, meshing with the rack. Two brackets are fixedly connected to the outer side of the fourth shaft. An anti-deformation plate is fixedly connected between each bracket. Two second movable grooves are formed at the top of the second L-shaped positioning plate. An anti-deformation component is installed. When the L-shaped positioning plate II rotates to the vertical position, the fixing block contacts the contact plate. In conjunction with the slide groove I, slider, rack, gear II, rotating shaft IV, bracket, and anti-deformation plate, the anti-deformation plate rotates to the top of the circuit board. This prevents the circuit board from deforming due to local high temperature during the disassembly process, avoids the circuit board from shifting its position, and makes the disassembly process of the equipment smoother.
[0010] Furthermore, the width of the second movable groove is greater than the width of the bracket, and the outer side of the anti-deformation plate does not contact the top of the second L-shaped positioning plate.
[0011] Furthermore, the bottom of the anti-deformation plate contacts the top of the circuit board, and an auxiliary unloading assembly is movably connected inside the processing chamber.
[0012] Furthermore, the auxiliary unloading assembly includes fixed rods, guide strips, observation windows, fixed frames, a movable robotic arm, an air pump, an unloading suction cup, and a guide slide. Fixed rods are fixedly connected to both ends of the left inner side of the processing chamber, and guide strips are fixedly connected to the outer sides of the fixed rods. A fixed frame is fixedly connected to the rear surface of the processing chamber, and an observation window is fixedly connected inside the fixed frame. A movable robotic arm is movably connected inside the fixed frame, and an air pump is fixedly connected to the top of the movable robotic arm. An unloading suction cup is fixedly connected to the bottom of the air pump, and a guide slide is fixedly connected to the right side of the processing chamber. With this auxiliary unloading assembly, when the equipment is running, the guide strips initially position the circuit boards on the feeding conveyor belt. After processing, the movable robotic arm is activated to suction the disassembled circuit boards onto the unloading suction cup, and then place them into the guide slide, allowing the circuit boards to slide out along the guide slide, thus achieving an automatic unloading process.
[0013] Furthermore, the width of the guide slide is greater than the width of the circuit board, and the size of the unloading suction cup is smaller than the size of the circuit board.
[0014] Furthermore, the bottom of the unloading suction cup is at a higher level than the top of the circuit board.
[0015] The advantages of this application are: (1) When the equipment starts the disassembly process, the motor is started and the L-shaped positioning plate 1 and L-shaped positioning plate 2 are rotated to a vertical position in coordination with the rotating shaft 1, bevel gear 1, bevel gear 2, pulley 1, belt, pulley 2, rotating shaft 3, and gear 1. This allows the circuit board to be automatically centered and fixed on the steering support equipment, so that the circuit board will not shift position when rotating. At the same time, after the processing is completed, the rack is lifted to drive the circuit board to move automatically upward, which facilitates unloading.
[0016] (2) When the L-shaped positioning plate II rotates to the vertical position, the fixing block contacts the contact plate and works with the slide groove I, slider, rack, gear II, rotating shaft IV, bracket and anti-deformation plate to rotate the anti-deformation plate to the top of the circuit board, so that the circuit board will not be deformed due to local high temperature during the disassembly process, and the circuit board will avoid positional displacement, thus making the disassembly process of the equipment smoother.
[0017] (3) When the equipment is running, the guide bar will initially position the circuit board on the feeding conveyor belt. After processing, the movable robotic arm will be started to adsorb the circuit board after disassembly onto the unloading suction cup, and then put into the guide slide, so that the circuit board slides out along the guide slide to realize the automatic unloading process.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.
[0021] Example 1, as Figures 1-4 As shown, a steerable board removal device for printed circuit boards includes a support leg 100. A processing chamber 200 is fixedly connected to the top of the support leg 100. A control panel 300 is fixedly connected to the front of the processing chamber 200. The control panel 300 controls the operation of various components. A drill bit position adjustment device 400 is movably connected to the top of the processing chamber 200. The drill bit position adjustment device 400 allows the position of the board removal drill bit 500 to be changed during processing. The board removal drill bit 500 is fixedly connected to the bottom of the drill bit position adjustment device 400. A feeding conveyor belt 600 is movably connected to the left side of the processing chamber 200 to facilitate loading of the equipment. A steering support device 700 is movably connected inside the processing chamber 200. Multiple fixing plates 902 are fixedly connected to the front and rear surfaces of the steering support device 700. A rotating shaft 901 is movably connected between every two fixing plates 902. A motor is fixedly connected to the left side of the rotating shaft 901. An electric locking device 903 is fixedly connected to the outer left end of the rotating shaft 901. An L-shaped positioning plate 904 is fixedly connected to the outer center of the rotating shaft 901. A bevel gear 905 is fixedly connected to the right side of the rotating shaft 901. The left and right sides of the steering support device 700... Multiple fixed plates 908 are fixedly connected to the surface. A rotating shaft 907 is movably connected between every two fixed plates 908. A bevel gear 906 is fixedly connected to the front side of the rotating shaft 907. A bevel gear 905 meshes with the bevel gear 906. The bevel gear 905 rotates counterclockwise, and the bevel gear 905 and the bevel gear 906 have the same size and number of teeth, thus allowing the bevel gear 905 and the bevel gear 906 to rotate synchronously. An L-shaped fixture is fixedly connected to the outer center of the rotating shaft 907. Position plate 2 909, pulley 1 910 is fixedly connected to the outer right end of shaft 1 901, steering support device 700 has a movable groove 1 914 inside, shaft 3 913 is movably connected inside the movable groove 1 914, pulley 2 912 is fixedly connected to the outer side of shaft 3 913, belt 911 is movably connected to the outer sides of pulley 1 910 and pulley 2 912, gear 1 915 is fixedly connected to the outer side of shaft 3 913, and the movable groove 1 914 has a movable... The device is connected to a lifting rack 916. A slide rail is provided inside the movable groove 914. The outer side of the lifting rack 916 is movably connected to the slide rail. The lifting rack 916 meshes with a gear 915. A lifting bar is fixedly connected to the top of the lifting rack 916. A certain length is reserved between the lifting rack 916 and the circuit board 800 so that the motor can continue to reverse. The lifting bar will only contact the bottom of the circuit board 800 after the L-shaped positioning plate 904 and the L-shaped positioning plate 909 are completely separated from the circuit board 800.
[0022] A circuit board 800 is placed on top of the steering support device 700. The inner surfaces of L-shaped positioning plate 1 904 and L-shaped positioning plate 2 909 are in contact with the surrounding surfaces of the circuit board 800. A receiving bin is provided inside the processing chamber 200, and a steering motor is fixedly connected to the bottom of the steering support device 700. The width of the movable groove 1 914 is greater than the width of the belt 911, and an anti-deformation component 1000 is movably connected inside the L-shaped positioning plate 2 909.
[0023] The system is equipped with L-shaped positioning plate 1 (904), L-shaped positioning plate 2 (909), and lifting rack 916. When the equipment begins the plate disassembly process, the motor is started, cooperating with shaft 1 (901), bevel gear 1 (905), bevel gear 2 (906), pulley 1 (910), belt 911, pulley 2 (912), shaft 3 (913), and gear 1 (915) to rotate L-shaped positioning plate 1 (904) and L-shaped positioning plate 2 (909) to a vertical position. This allows the circuit board 800 to be automatically centered and fixed on the steering support device 700, preventing the circuit board 800 from shifting position during rotation. After processing is completed, the lifting rack 916 drives the circuit board 800 to move automatically upward for easy unloading.
[0024] In practical use, the above-mentioned equipment is activated by starting the feeding conveyor belt 600, causing the circuit board 800 to slide from the feeding conveyor belt 600 onto the steering support device 700. At this time, the motor is started, causing the rotating shaft 901 to rotate, which in turn drives the L-shaped positioning plate 904 to rotate to a vertical position, automatically aligning the front and rear sides of the circuit board 800. Simultaneously, the rotating shaft 901 drives the pulley 910 to rotate, which in turn drives the belt 911 to rotate, which in turn drives the pulley 912 to rotate, which in turn drives the rotating shaft 913 to rotate, which in turn drives the gear 915 to rotate, which in turn drives the lifting rack 915. 16 moves downwards, simultaneously causing the rotating shaft 901 to drive the bevel gear 905 to rotate, which in turn drives the bevel gear 906 to rotate, which in turn drives the rotating shaft 907 to rotate. The rotating shaft 907 then drives the L-shaped positioning plate 909 to rotate to a vertical position, automatically aligning the left and right sides of the circuit board 800 and thus automatically fixing the circuit board 800. At the same time, the electric locking device 903 is activated to prevent the circuit board 800 from shifting position during rotation. After the disassembly process is completed, the motor reverses and resets, causing the lifting rack 916 to move upwards. The lifting rack then drives the circuit board 800 upwards to disengage from the steering support device 700, facilitating subsequent unloading.
[0025] Example 2, as Figures 1-6As shown, based on Embodiment 1, the anti-deformation component 1000 includes a fixing block 1001, a contact plate 1002, a spring 1003, a first slide groove 1004, a slider 1005, a rack 1006, a second gear 1007, a fourth rotating shaft 1008, a third fixing plate 1009, a bracket 1010, a second movable groove 1011, and an anti-deformation plate 1012. Fixing blocks 1001 are fixedly connected to both sides of the steering support device 700. A first slide groove 1004 is provided inside the L-shaped positioning plate 909. The first slide groove 1004 allows the rack 1006 to move along the direction of the first slide groove 1004. Multiple sliders 1005 are movably connected inside the first slide groove 1004. A rack 1006 is fixedly connected to the inner side of each slider 1005. One end of the rack 1006 near the center of the circuit board 800 is fixedly connected to... There is a contact plate 1002, and a spring 1003 is fixedly connected between the contact plate 1002 and the L-shaped positioning plate 2 909. Multiple fixing plates 3 1009 are fixedly connected to the outer surface of the L-shaped positioning plate 2 909. A rotating shaft 4 1008 is movably connected inside every two fixing plates 3 1009. A gear 2 1007 is fixedly connected to the left side of the rotating shaft 4 1008. The gear 2 1007 meshes with a rack 1006. Two brackets 1010 are fixedly connected to the outer side of the rotating shaft 4 1008. An anti-deformation plate 1012 is fixedly connected between each bracket 1010. Two movable grooves 2 1011 are opened on the top of the L-shaped positioning plate 2 909. A locking device is fixedly connected inside the movable groove 2 1011. The locking device can lock the bracket 1010, thereby preventing the anti-deformation plate 1012 from loosening due to vibration.
[0026] The width of the movable groove 1011 is greater than the width of the bracket 1010. The outer side of the anti-deformation plate 1012 does not contact the top of the L-shaped positioning plate 909. The bottom of the anti-deformation plate 1012 contacts the top of the circuit board 800. An auxiliary unloading assembly 1100 is movably connected inside the processing chamber 200.
[0027] An anti-deformation component 1000 is installed. When the L-shaped positioning plate 909 rotates to the vertical position, the fixing block 1001 contacts the contact plate 1002. In conjunction with the sliding groove 1004, slider 1005, rack 1006, gear 1007, rotating shaft 1008, bracket 1010, and anti-deformation plate 1012, the anti-deformation plate 1012 rotates to the top of the circuit board 800. This prevents the circuit board 800 from deforming due to localized high temperatures during the disassembly process, avoids positional displacement of the circuit board 800, and makes the disassembly process of the equipment smoother.
[0028] In practical use, when the L-shaped positioning plate 909 rotates to a vertical position, the fixing block 1001 contacts the contact plate 1002, causing the contact plate 1002 to move backward along the slide groove 1004. This compresses the spring 1003, causing the slider 1005 to follow the contact plate 1002 and move backward along the slide groove 1004. The slider 1005 then drives the rack 1006 to move backward, causing the rack 1006 to drive the gear 1007 to rotate. The gear 1007 then drives the rotating shaft 1008 to rotate, causing the rotating shaft 1008 to rotate. This causes the bracket 1010 to rotate, and the bracket 1010 to drive the anti-deformation plate 1012 to rotate to the top of the circuit board 800. This prevents the circuit board 800 from deforming due to localized high temperatures during disassembly, avoiding positional shift of the circuit board 800 and making the disassembly process smoother.
[0029] Example 3, as Figures 2-8 As shown, based on Embodiment 1 or Embodiment 2, the auxiliary unloading assembly 1100 includes a fixed rod 1101, a guide strip 1102, an observation window 1103, a fixed frame 1104, a movable robotic arm 1105, an air suction pump 1106, an unloading suction cup 1107, and a guide slide plate 1108. The fixed rod 1101 is fixedly connected to both ends of the left inner side of the processing chamber 200, and the guide strip 1102 is fixedly connected to the outer side of the fixed rod 1101. The fixed frame 1104 is fixedly connected to the rear surface of the processing chamber 200. An observation window 1103 is fixedly connected inside the frame 1104. The observation window 1103 is set so that the operation of the equipment can be monitored in real time. A movable robotic arm 1105 is movably connected inside the fixed frame 1104. An air suction pump 1106 is fixedly connected to the top of the movable robotic arm 1105. A discharge suction cup 1107 is fixedly connected to the bottom of the air suction pump 1106. The discharge suction cup 1107 is set so that the circuit board 800 can be driven by the discharge suction cup 1107. A guide slide plate 1108 is fixedly connected to the right side of the processing chamber 200.
[0030] The width of the guide slide 1108 is greater than the width of the circuit board 800, and the size of the unloading suction cup 1107 is smaller than the size of the circuit board 800. The bottom horizontal height of the unloading suction cup 1107 is higher than the top horizontal height of the circuit board 800. When the unloading suction cup 1107 is in standby mode, its position is higher than the circuit board 800, and when the unloading suction cup 1107 is in working mode, its position is lower than the circuit board 800.
[0031] An auxiliary unloading component 1100 is set up. When the equipment is running, the guide bar 1102 initially positions the circuit board 800 on the feeding conveyor belt 600. After processing is completed, the movable robotic arm 1105 is started to adsorb the circuit board 800 after disassembly onto the unloading suction cup 1107, and then put it into the guide slide plate 1108, so that the circuit board 800 slides out along the guide slide plate 1108, realizing the automatic unloading process.
[0032] In practical use, after the equipment completes the board removal process, the circuit board 800 remains on the steering support device 700. At this time, the movable robotic arm 1105 is activated, rotating to the upper side of the circuit board 800. The suction pump 1106 is then activated, causing the suction pump 1106 to drive the unloading suction cup 1107 to suck up the circuit board 800. The movable robotic arm 1105 is then rotated to the upper side of the guide slide plate 1108, and the suction pump 1106 is turned off, causing the circuit board 800 to fall onto the surface of the guide slide plate 1108 and slide to the bottom, thus realizing the automatic unloading process. During loading, the circuit board 800 on the feeding conveyor belt 600 is initially positioned by the guide bar 1102, making the process of the circuit board 800 sliding into the steering support device 700 smoother.
[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
