Description

Technical Field

[0001] This invention relates to the field of COB packaging technology, specifically an energy-saving and low-power COB packaging device. Background Technology

[0002] Chip-on-board (COB) is a packaging technology that directly mounts bare chips onto a printed circuit board. COB technology directly bonds chips to the PCB and makes electrical connections using wires or solder balls, and finally protects them with encapsulation materials (such as epoxy resin). COB technology is widely used in LED lighting, consumer electronics, automotive electronics, medical devices and other fields, and has the advantages of high integration, low cost and small size.

[0003] For example, a multicolor COB light source packaging device, as disclosed in Chinese Patent Publication No. CN114242872B, includes a support platform. The support platform has a ring structure, and a base is mounted on the lower side of the support platform via a support ring. A rotating platform is provided on the upper side of the support platform, and an upper alignment plate is arranged parallel above the rotating platform. The upper alignment plate is locked to the free end on the outside. A dam support plate is mounted on the lower side of the middle part of the upper alignment plate via a telescopic shaft. A dam treatment component is provided on the dam support plate. The axis of the telescopic shaft corresponds to the axis of the output shaft of the rotating motor.

[0004] Currently, commercially available COB packaging devices can only apply epoxy resin. However, since epoxy resin is released without restriction, it flows freely on the PCB board, potentially covering other components and causing mis-coverage. Therefore, an improved device is needed to address this issue. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides an energy-saving and low-power COB packaging device.

[0006] The technical solution adopted by this invention to solve its technical problem is: an energy-saving and low-power COB packaging device, including a support device, a positioning component fixedly installed on the side end of the support device, and a PCB board placed on the top end of the support device. The support device includes a placement cavity, a special-shaped bracket, a support base, a movable slot, a second gear, a support base, a second double-control switch, a third gear, a third rack, and a Z-shaped movable frame. The second double-control switch is fixedly installed on the right side of the top end of the support base, the support base is fixedly installed on the left side of the support base, the placement cavity is fixedly installed on the top end of the support base near the second double-control switch, the movable slot is opened at both ends of the support base, the special-shaped bracket is slidably inserted into the interior of the movable slot, the third rack is fixedly installed on the special-shaped bracket, the Z-shaped movable frame is fixedly installed between the two special-shaped brackets, and the third gear and the second gear are respectively rotatably installed on the front and rear ends of the support base near the Z-shaped movable frame.

[0007] Specifically, the positioning component includes an accumulation device and a transmission device, with the accumulation device threaded onto the transmission device.

[0008] Specifically, the accumulation device includes a displacement bracket, an alignment sleeve, an electric vacuum suction cup, a plastic ring, a hexagonal rod, a return spring, a first rack, a supporting horizontal plate, an accumulation cavity, a transfer cavity, transfer blades, a connecting shaft, a second rack, a first gear, and a connecting pipe. The accumulation cavity is fixedly installed at the top of the supporting horizontal plate, the displacement bracket is fixedly installed at the center of the right side of the supporting horizontal plate, the first rack is fixedly installed at both ends of the supporting horizontal plate away from the displacement bracket, the connecting pipe is fixedly installed at the inner center of the accumulation cavity and the supporting horizontal plate, and the transfer cavity is fixedly installed between the two connecting pipes. The transfer blades are rotatably installed inside the transfer cavity. The connecting shaft is fixedly installed at the center of both sides of the transfer blades. The first gear is fixedly installed at the center of the side end of the connecting shaft away from the transfer blades. The hexagonal rod is symmetrically slidably inserted into the inside of the support cross plate. The alignment sleeve is fixedly installed at the bottom end of the hexagonal rod. The return spring is symmetrically fixedly installed between the support cross plate and the alignment sleeve, and the return spring is located on the outer ring of the hexagonal rod. The electric vacuum suction cup is fixedly installed at the bottom end of the alignment sleeve. The plastic ring is placed at the bottom end of the electric vacuum suction cup. The second rack is fixedly installed on the side end of the hexagonal rod.

[0009] Specifically, the transmission device includes a first dual-control switch, a support frame, a drive motor, and a lead screw. The drive motor is fixedly installed at the bottom center of the support frame, the lead screw is fixedly installed at the top center of the drive motor, and the first dual-control switch is fixedly installed at the top of the side end of the support frame away from the lead screw.

[0010] Specifically, the displacement bracket is threaded onto the outer ring of the lead screw, and the support frame is fixedly installed on the side of the support base near the second double-control switch.

[0011] Specifically, the interiors of the accumulation cavity and the transfer cavity are both hollow, and the accumulation cavity, the connecting pipe and the transfer cavity are interconnected. The outer surface of the transfer blade has a groove, the first gear meshes with the second rack, and the displacement bracket has a threaded hole inside.

[0012] Specifically, the support plate has grooves on both ends near the first rack, the electric vacuum suction cup is electrically connected to the first and second double-control switches, the third gear meshes with the second gear, and the transmission ratio between the second gear and the third gear is 1:10.

The support gantry is fixedly installed at the top front end of the support base, the hydraulic cylinder is symmetrically fixedly installed at the top of the support gantry, and the heater is fixedly installed at the bottom end of the hydraulic cylinder.

[0016] The beneficial effects of this invention are: In use, the invention utilizes a drive motor that, during operation, moves a supporting horizontal plate downward via a lead screw, allowing the plastic ring to contact the surface of the PCB board. Simultaneously, a return spring ensures the supporting horizontal plate continues to move downward, enabling the transfer blades to draw epoxy resin from the accumulation cavity into the connecting pipe. The connecting pipe then discharges the epoxy resin onto the top of the PCB board. The plastic ring prevents the epoxy resin from flowing to the sides. Furthermore, the supporting horizontal plate triggers a second dual-control switch, de-energizing the electric vacuum suction cup. The plastic ring remains on the top of the PCB board, effectively restricting the epoxy resin flow. When the supporting horizontal plate returns to its original position, a first rack and second gear reset the Z-shaped movable frame, allowing it to push the plastic ring into contact with the electric vacuum suction cup, thus refilling the electric vacuum suction cup with the plastic ring.

[0024] like Figure 2 The positioning component 1 includes an accumulation device 4 and a transmission device 5, with the accumulation device 4 threadedly connected to the transmission device 5.

[0025] like Figure 3 and Figure 4The accumulation device 4 includes a displacement bracket 6, an alignment sleeve 7, an electric vacuum suction cup 8, a plastic ring 9, a hexagonal rod 10, a return spring 11, a first rack 12, a supporting horizontal plate 13, an accumulation cavity 14, a transfer cavity 15, a transfer blade 16, a connecting shaft 17, a second rack 18, a first gear 19, and a connecting pipe 20. The accumulation cavity 14 is fixedly installed at the top of the supporting horizontal plate 13. The displacement bracket 6 is fixedly installed at the center of the right side of the supporting horizontal plate 13. The first rack 12 is fixedly installed at the front and rear ends of the supporting horizontal plate 13 away from the displacement bracket 6. The connecting pipe 20 is fixedly installed at the center inside the accumulation cavity 14 and the supporting horizontal plate 13. The transfer cavity 15 is fixedly installed between the two connecting pipes 20. The transfer blade 16 is rotatably installed inside the transfer cavity 15. The connecting shaft 17 is fixedly installed on both sides of the transfer blade 16. At the center, the first gear 19 is fixedly installed on the side center of the connecting shaft 17 away from the transfer blade 16. The hexagonal rod 10 is symmetrically slidably inserted into the inside of the support horizontal plate 13. The alignment sleeve 7 is fixedly installed at the bottom end of the hexagonal rod 10. The return spring 11 is symmetrically fixedly installed between the support horizontal plate 13 and the alignment sleeve 7, and the return spring 11 is located on the outer ring of the hexagonal rod 10.

The second rack 18 is fixedly installed on the side end of the hexagonal rod 10. An electromagnetic valve is installed at the bottom end of the inside of the accumulation cavity 14, and the electromagnetic valve is interconnected with the connecting pipe 20 at the bottom end of the inside of the accumulation cavity 14. When the electromagnetic valve is opened or closed, it can control whether the epoxy resin flows in the connecting pipe 20, so as to avoid premature release of the epoxy resin.

[0026] like Figure 5 The transmission device 5 includes a first double-control switch 21, a support frame 22, a drive motor 23, and a lead screw 24. The drive motor 23 is fixedly installed at the bottom center of the support frame 22, and the lead screw 24 is fixedly installed at the top center of the drive motor 23. The first double-control switch 21 is fixedly installed at the top of the side end of the support frame 22 away from the lead screw 24. A vertical groove is provided inside the support frame 22, and the displacement bracket 6 is slidably inserted into the vertical groove, so that the support plate 13 can slide up and down in a straight line, thus preventing the displacement bracket 6 from tilting.

[0027] The displacement bracket 6 is threaded onto the outer ring of the lead screw 24. The support frame 22 is fixedly installed on the side of the support base 30 near the second double-control switch 31. The interiors of the accumulation cavity 14 and the transfer cavity 15 are both hollow, and the accumulation cavity 14, the connecting pipe 20, and the transfer cavity 15 are interconnected. The outer ring surface of the transfer blade 16 has a groove. The first gear 19 meshes with the second rack 18. The displacement bracket 6 has a threaded hole inside. The support plate 13 has grooves on both ends near the first rack 12. The electric vacuum suction cup 8 is electrically connected to the first double-control switch 21 and the second double-control switch 31. The connection is made so that the third gear 32 meshes with the second gear 29, and the transmission ratio between the second gear 29 and the third gear 32 is 1:10. The top of the Z-shaped movable frame 34 is flush with the inner top of the support base 27, and the support base 27 has a displacement groove inside. The third gear 32 meshes with the third rack 33, and the second gear 29 meshes with the first rack 12. The thickness of the third rack 33, the third gear 32 and the first rack 12 is 1 cm, and the thickness of the second gear 29 is 3 cm. The second double-control switch 31 and the first double-control switch 21 are vertically aligned with the end of the support plate 13 near the displacement bracket 6.

[0028] The working principle of Example 1 is as follows: In use, plastic rings 9 are first stacked inside the placement cavity 25. The placement cavity 25 is interconnected with the support base 27, allowing the bottom plastic ring 9 to be placed inside the support base 27. Then, the PCB board 3 is placed on the support base 30 until the PCB board 3 is perpendicularly aligned with the alignment sleeve 7. Next, the drive motor 23 is started, causing the lead screw 24 to rotate clockwise. The displacement bracket 6 is threaded onto the outer ring of the lead screw 24, allowing the lead screw 24 to move the displacement bracket 6 and the support plate 13 downwards. When the support plate 13 moves downwards, it engages the first rack 12 with the second gear 29, thereby causing the second gear 29 to rotate the third gear 32. The third gear 32 can drive the third rack 33 to move closer to the interior of the support base 27, allowing the Z-shaped movable frame 34 to retract into the interior of the support base 27. Simultaneously, when the support plate 13 moves downwards, the return spring 11 prevents the plastic ring 9 from jamming with the Z-shaped movable frame 34. Subsequently, when the return spring 11 is compressed to its limit position, the first rack 12 passes through the second gear 29, thereby allowing the third gear 32 to drive the third rack 33 to move to its limit position, enabling the Z-shaped movable frame 34 to fully enter the interior of the support base 27. This prevents interference between the support plate 13 and the Z-shaped movable frame 34 when the support plate 13 moves downwards. Furthermore, an electromagnetic valve is installed in the connecting pipe 20 inside the accumulation cavity 14. When the accumulation cavity 14 is in the lower position... In the lowered state, the solenoid valve can be energized to seal the inside of the connecting pipe 20, preventing epoxy resin from flowing outward when the transfer blade 16 rotates. Subsequently, after the Z-shaped movable frame 34 is reset, the elasticity of the reset spring 11 will drive the alignment sleeve 7 to reset downward. When the alignment sleeve 7 resets downward, the solenoid valve inside the accumulation cavity 14 can be opened, allowing the accumulation cavity 14 to communicate with the transfer cavity 15. At this time, epoxy resin will flow into the groove inside the transfer blade 16 through the connecting pipe 20 at the bottom of the accumulation cavity 14. When the support plate 13 moves downward, it can drive the plastic ring 9 to first contact the surface of the PCB board 3, positioning the PCB board 3. Subsequently, the support plate 13 can continue to move downward until the support plate 13 contacts the second double control. When switch 31 is engaged, the second double-control switch 31 can be triggered, de-energizing the electric vacuum suction cup 8. At this time, the electric vacuum suction cup 8 loses its suction force, and the plastic ring 9 remains on the top of the PCB board 3. Simultaneously, as the supporting horizontal plate 13 continues to move downward, it can drive the first gear 19 to move downward along the surface of the second rack 18, causing the connecting shaft 17 to drive the transfer blade 16 to rotate. When the transfer blade 16 rotates, it can drive the groove to rotate vertically downward, so that the epoxy resin inside the groove can flow out through the connecting pipe 20 at the bottom of the transfer cavity 15. The connecting pipe 20 is vertically aligned with the plastic ring 9, allowing the epoxy resin to flow into the released plastic ring 9 and the top of the PCB board 3. Furthermore, as the transfer blade 16 rotates,For areas without grooves, the connecting pipe 20 at the bottom of the accumulation cavity 14 can be sealed to prevent epoxy resin from falling into the transfer cavity 15. Simultaneously, the solenoid valve inside the accumulation cavity 14 can be opened to close the connecting pipe 20 at the bottom of the accumulation cavity 14. Then, the drive motor 23 is turned on, causing the lead screw 24 to rotate counterclockwise, allowing the support plate 13 to move upwards. At this point, the support plate 13 can move away from the alignment sleeve 7, and the first gear 19 can pass over the surface of the second rack 18, thus allowing the first gear 19 to drive the transfer blade 16 to rotate and reset, facilitating the rotation of the groove inside the transfer blade 16 to a perpendicular alignment with the bottom of the accumulation cavity 14. After the electric vacuum suction cup 8 disengages from the plastic ring 9, the support plate 13 can continue to move upwards. When the support plate 13 moves past the support base 27, it can drive the first rack 12 to mesh with the second gear 29, allowing the second gear 29 to pass again through the third gear 3. 2. The third rack 33 is displaced, causing the support plate 13 to return to its upward position. Simultaneously, the third rack 33, via the Z-shaped movable frame 34, pushes the plastic ring 9 inside the support base 27 towards the end closer to the second double-control switch 31. Furthermore, when the Z-shaped movable frame 34 is inside the support base 27, it can catch plastic rings 9 falling from the upper layer of the placement cavity 25, ensuring that only one plastic ring 9 is transferred per displacement. Then, when the support plate 13 moves upward to its limit position, it causes the first rack 12 to move along the second gear 29 to its full range, allowing the Z-shaped movable frame 34 to move the plastic ring 9 to the bottom of the electric vacuum suction cup 8. At the same time, when the support plate 13 moves upward to its limit position, it contacts the first double-control switch 21, thus activating the electric vacuum suction cup 8 to adhere and fix the plastic ring 9, preventing the plastic ring 9 from falling off the bottom of the electric vacuum suction cup 8 during subsequent repositioning of the Z-shaped movable frame 34, completing the operation.

[0029] Example 2

[0030] Based on Example 1, such as Figure 8 As shown, the support base 30 also includes a hydraulic cylinder 35, a support gantry 36, and a heater 37. The support gantry 36 is fixedly installed at the top front end of the support base 30, the hydraulic cylinder 35 is symmetrically fixedly installed at the top of the support gantry 36, and the heater 37 is fixedly installed at the bottom end of the hydraulic cylinder 35.

[0031] In implementing this embodiment, after the epoxy resin is added to the top of the PCB board 3, the PCB board 3 can be moved to the bottom of the heater 37 until the PCB board 3 and the heater 37 are vertically aligned. Then, the heater 37 is powered on to apply heat to the top surface of the PCB board 3, thereby accelerating the drying of the epoxy resin. At the same time, by opening the hydraulic cylinder 35, the heater 37 is moved up and down, so that the distance between the heater 37 and the PCB board 3 can be adjusted, which is convenient for drying different PCB boards 3.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
