Description

Technical Field

[0002] LEDs are widely used electronic devices with advantages such as energy efficiency and long lifespan. An LED is a package that generally includes a substrate, an LED chip on the substrate, a phosphor layer covering the LED chip, and a transparent layer covering the phosphor layer. In actual production, LED packages on a board are arranged in a matrix and are divided to obtain individual LED packages. Under normal circumstances, after packaging, inspection is required before division, and this inspection includes visual inspection.

[0003] LED packaging testing requires the use of a microscope. LED packaging structures are small and thin, making it inconvenient for staff to move them during testing.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] Please see Figure 1-10 A testing fixture for LED packaging with good stability includes a first moving mechanism 1, a clamping mechanism 2, a second moving mechanism 3, a lifting mechanism 4, and a stabilizing mechanism 5. The first moving mechanism 1 includes a fixing block 11, a first toothed plate 12 is fixedly disposed inside the fixing block 11, a stabilizing plate is fixedly disposed at one end of the first toothed plate 12, and a first damping rotating shaft 14 is disposed inside the fixing block 11, and a toothed ring that meshes with the first toothed plate 12 is fixedly disposed on the surface of the first damping rotating shaft 14.

[0033] The clamping mechanism 2 includes a fixing plate 21 fixedly disposed on the top of the first toothed plate 12. The top of the fixing plate 21 is hinged to a clamping plate 22, and the clamping plate 22 has an observation hole 23 inside, through which the assembled LED package can be observed.

[0034] The second moving mechanism 3 includes a mounting block 31. A second toothed plate 32 is fixedly disposed inside the mounting block 31. A second damping shaft 33 is disposed inside the mounting block 31, and a toothed disc that meshes with the second toothed plate 32 is fixedly disposed on the surface of the second damping shaft 33. A support rod 34 is fixedly disposed on the top of the second damping shaft 33. The top of the support rod 34 extends through to the top of the mounting block 31 and is fixedly connected to the surface of the fixed block 11. A limit plate 36 is fixedly disposed on one side of the inner wall of the mounting block 31. The surface of the support rod 34 is movably connected to the interior of the limit plate 36. Two support plates 37 are fixedly installed on the surface of the device. The two support plates 37 are located at the top and bottom of the limiting plate 36, respectively. The fixing block 11 and the mounting block 31 are both composed of two cover plates connected by bolts to the middle shell, which facilitates disassembly and maintenance in the later stage. The LED package to be tested is assembled by the fixing plate 21 and the clamping plate 22. It moves in the front, back and left and right directions by the first moving mechanism 1 and the second moving mechanism 3. The movement process is stable and can be stopped and positioned at will, which ensures the testing efficiency of the LED package. At the same time, it is more stable when assembling the LED package, and has broad application prospects.

[0035] The lifting mechanism 4 includes a support cylinder 41 and an operating block 45. A lifting rod 42 is movably arranged inside the support cylinder 41. The top of the lifting rod 42 is fixedly connected to the bottom of the mounting block 31. Operating pads 46 are provided on both sides of the operating block 45. A spring 47 is provided inside the operating block 45. The two ends of the spring 47 extend into the interior of the two operating pads 46 respectively. The interior of the operating block 45 is connected to the support cylinder 41 through a conveying pipe 49.

[0036] The stabilizing mechanism 5 includes a mounting base plate 51. The bottom of the support cylinder 41 and the operating block 45 are fixedly connected to the top of the mounting base plate 51. A suction cup 52 is provided at the bottom of the mounting base plate 51. A communicating cavity 53 is opened inside the mounting base plate 51. A control cylinder 54 is fixedly provided at the top of the mounting base plate 51. The control cylinder 54 is connected to the suction cup 52 through the communicating cavity 53. A lifting rod 55 is movably provided inside the control cylinder 54, and a lifting plate 56 is fixedly provided at the bottom of the lifting rod 55.

[0037] This LED packaging testing fixture boasts high stability. It comprises a first moving mechanism 1, a clamping mechanism 2, and a second moving mechanism 3. The LED package to be tested is assembled using a fixed plate 21 in conjunction with a clamping plate 22. The fixture moves stably in all directions (front, back, left, and right) via the first moving mechanism 1 and the second moving mechanism 3, ensuring stable movement and arbitrary stopping and positioning, thus guaranteeing efficient LED package testing and providing greater stability during assembly. The first moving mechanism 1, with its stabilizing block 13 supporting the first toothed plate 12 via first ball bearings 131, ensures that the first toothed plate 12 moves smoothly and reliably. The resistance of the first damping shaft 14 is reduced, thus minimizing additional resistance. When the first toothed plate 12 moves, it drives the protective shell 16 to move. The protective shell 16 shields the tooth surface of the first toothed plate 12, ensuring the integrity and appearance of the device. Furthermore, the protective shell 16 is movably mounted on the surface of the fixed block 11 via the second ball bearing 17, making movement more stable and further reducing additional resistance. By setting the second moving mechanism 3, and the third ball bearing 35 and the fourth ball bearing 371, the resistance of the support rod 34, excluding the second damping shaft 33, is reduced to the maximum extent, allowing the support rod 34 to... 4. Movement relies solely on the resistance of the second damping shaft 33, allowing the support rod 34 to move more smoothly. Furthermore, the two sets of fourth ball bearings 371, in conjunction with the two support plates 37, prevent the support rod 34 from tilting, further ensuring the stability of the device. By setting up the stabilizing mechanism 5, rotating the lifting rod 55 raises and extracts air from inside the suction cup 52, thus ensuring stable adhesion between the suction cup 52 and the tabletop, guaranteeing the stability of the device. Opening the valve inside the exhaust pipe 58 connects external air to the suction cup 52, causing the suction cup 52 to detach from the tabletop. This design facilitates user movement of the device, is easy to operate, provides stable placement, and is easy to move, with broad application prospects. By setting up a lifting mechanism 4, pressing the two operating plates 471 allows air inside the operating block 45 to enter the support cylinder 41 and lift the lifting rod 42, making it convenient for users to adjust the height of the fixed plate 21. When it is necessary to lower the mounting block 31, the valve inside the connecting pipe 492 is opened, allowing the air pressed down by the lifting rod 42 to be discharged through the connecting pipe 492. The lifting method is simple and easy to operate, and the air lifting method makes the height adjustment distance more precise.

[0038] Specifically, a stabilizing block 13 is fixedly disposed at one end of the first toothed plate 12. A first ball bearing 131 is fixedly disposed on the surface of the stabilizing block 13. The surface of the first ball bearing 131 is movably connected to the inner wall of the fixed block 11. A groove 18 is formed on the surface of the fixed block 11. An adsorption block 15 is fixedly disposed on the front side of the first toothed plate 12. A first magnetic block 151 is fixedly embedded on the right side of the adsorption block 15. A protective shell 16 is movably disposed on the surface of the fixed block 11. A second magnetic block 161 is fixedly disposed on the left side of the inner wall of the protective shell 16. The side of the second magnetic block 161 away from the protective shell 16 extends into the interior of the adsorption block 15 and is magnetically connected to the first magnetic block 151. A second ball bearing 17 is movably embedded inside the protective shell 16. The surface of the second ball bearing 17 extends into the interior of the groove 18. The stabilizing block 13... The first ball bearing 131 is movably disposed inside the fixed block 11, and the stabilizing block 13 supports the first toothed plate 12. When the first toothed plate 12 moves, it relies on the resistance of the first damping shaft 14, reducing the generation of other additional resistance. When the first toothed plate 12 moves, it drives the protective shell 16 to move. The protective shell 16 is movably disposed on the surface of the fixed block 11 through the second ball bearing 17, further reducing the generation of additional resistance and facilitating the user to move the fixed plate 21. The protective shell 16 shields the tooth surface of the first toothed plate 12, ensuring the integrity and appearance of the device. The cooperation of the first magnetic block 151 and the second magnetic block 161 allows the protective shell 16 to move and reset even when the first toothed plate 12 is retracted into the fixed block 11. The protective shell 16 is detachable, which facilitates the user's assembly and does not affect the user's disassembly of the fixed block 11.

[0039] Specifically, a connecting block 24 is fixedly provided on the front of the fixing plate 21, and a pull plate 25 is fixedly provided on the front of the clamping plate 22. A pull rod 26 is movably provided inside the connecting block 24. The top end of the pull rod 26 extends through to the top of the pull plate 25 and is fixedly provided with a locking block 27. A pressure plate 28 is fixedly provided on the surface of the pull rod 26. A compression spring 281 is provided on the top of the pressure plate 28, and the top end of the compression spring 281 overlaps with the bottom of the connecting block 24. A through hole is opened inside the pull plate 25, and the length of the through hole is greater than the length of the locking block 27. By rotating the locking block 27 90 degrees by the pull rod 26, the locking block 27 is aligned with the through hole. At the same time, it is pushed down into the through hole by the spring 281. The clamping plate 22 can then be flipped by the pull plate 25, which facilitates the user to assemble or remove LED packages. The operation is simple and ensures the stability of the LED package.

[0040] Specifically, an air inlet pipe 48 is fixedly installed on the top of the operating block 45, and an air inlet one-way valve is fixedly installed inside the air inlet pipe 48. The air inlet one-way valve prevents air inside the operating block 45 from being discharged through the air inlet pipe 48. A delivery one-way valve 491 and a connecting pipe 492 are installed inside the delivery pipe 492. A valve is installed inside the connecting pipe 492. Operating plates 471 are fixedly installed at both ends of the spring 47. The operating pad 46 is a rubber pad. By pressing the two operating plates 471 with the two operating pads 46, air inside the operating block 45 enters the support cylinder 4 through the delivery one-way valve 491 and the valve. Inside the support cylinder 41, the one-way valve 491 prevents the gas inside the support cylinder 41 from flowing back into the operating block 45. When the operating plate 471 is released, the spring 47 rebounds and the operating plate 471 drives the operating pad 46 to reset, allowing the operating pad 46 to draw in external air through the air inlet one-way valve. When the mounting block 31 needs to be lowered, the valve inside the connecting pipe 492 is opened, allowing the air inside the support cylinder 41 to connect with the outside, causing the lifting rod 42 to press down the air, which is then discharged through the conveying pipe 49 and the connecting pipe 492. The lifting method is simple and easy to operate, and the height adjustment distance is more precise through air lifting.

[0041] Specifically, a limiting cylinder 44 is movably provided on the surface of the support cylinder 41. The top of the limiting cylinder 44 is fixedly connected to the bottom of the mounting block 31. A limiting block 411 is fixedly provided on the surface of the support cylinder 41. A limiting groove 441 is formed inside the limiting cylinder 44. The end of the limiting block 411 away from the support cylinder 41 extends into the limiting groove 441. A first sealing plate 43, which is a rubber plate, is fixedly provided at the bottom of the lifting rod 42. The setting of the limiting cylinder 44 allows the mounting block 31 to slide on the surface of the limiting groove 441 inside the limiting cylinder 44 when the lifting rod 42 drives the mounting block 31 to rise. This prevents the mounting block 31 from rotating and makes the rise of the mounting block 31 more stable. The setting of the first sealing plate 43 ensures the sealing effect inside the support cylinder 41, thereby causing air to push up the second sealing plate 57.

[0042] Specifically, the top of the mounting block 31 has a movable hole 38, and the support rod 34 passes through the movable hole 38 and is fixedly connected to the mounting block 31. The length of the movable hole 38 is less than the length of the limiting plate 36. Sponge blocks 39 are fixedly installed on both sides of the inner wall of the movable hole 38. The opposing surfaces of the two sponge blocks 39 are movably connected to the opposing surfaces of the support rod 34. The length of the movable hole 38 is less than the length of the limiting plate 36, so that the movable length of the support rod 34 inside the limiting plate 36 is not less than the length of the movable hole 38. The compressible nature of the sponge blocks 39 allows the two sponge blocks 39 to cover the movable hole 38 except at the position of the support rod 34, ensuring the appearance of the device.

[0043] Specifically, a third ball bearing 35 is movably embedded on the surface of the support rod 34. The surface of the third ball bearing 35 is movably connected to the inner wall of the limiting plate 36. Two sets of fourth ball bearings 371 are movably embedded on the opposite surfaces of the two support plates 37. The surfaces of the two sets of fourth ball bearings 371 are movably connected to the top and bottom of the limiting plate 36, respectively. The arrangement of the third ball bearing 35 and the fourth ball bearings 371 minimizes the resistance of the support rod 34 except for the second damping shaft 33, allowing the support rod 34 to move solely by the resistance of the second damping shaft 33 itself. This makes the movement of the support rod 34 smoother. During assembly, only a suitable damping shaft needs to be selected. Furthermore, the two sets of fourth ball bearings 371, in conjunction with the two support plates 37, prevent the support rod 34 from tilting, further ensuring the stability of the device.

[0044] Specifically, the lifting rod 55 is connected to the control cylinder 54 by a threaded connection. A second sealing plate 57, which is a rubber plate, is fixedly installed at the bottom of the lifting plate 56. An exhaust pipe 58 is fixedly installed inside the control cylinder 54, with one end of the exhaust pipe 58 extending to the outside of the control cylinder 54. A valve is installed inside the exhaust pipe 58. Rotating the lifting rod 55 causes the lifting plate 56 and the second sealing plate 57 to rise, allowing the second sealing plate 57 to draw air from the connecting cavity 53 and the suction cup 52, thereby ensuring that the suction cup 52 is stably adsorbed onto the table, thus ensuring the stability of the device. Opening the valve inside the exhaust pipe 58 allows external air to connect with the control cylinder 54, the connecting cavity 53, and the suction cup 52 through the valve, causing the suction cup 52 to detach from the table, making it convenient for the user to move the device. The operation is simple, the placement is stable, and it is easy to move.

[0045] Specifically, the length of the fixing block 11 is greater than the length of the fixing plate 21, and half the length of the mounting block 31 is greater than the width of the fixing plate 21. The device is placed on one side of the microscope, with the clamping mechanism 2 facing the inspection area of ​​the microscope. After the LED package is placed inside the fixing plate 21, the fixing plate 21 is pulled to move to the inspection area of ​​the microscope through the first toothed plate 12. The length of the fixing block 11 is greater than the length of the fixing plate 21, and half the length of the mounting block 31 is greater than the width of the fixing plate 21, so that both the horizontally and vertically arranged LED packages inside the fixing plate 21 can be fully inspected.

[0046] In use, the device is placed to one side of the microscope, with the clamping mechanism 2 facing the microscope's detection area. Rotating the lifting rod 55 raises the lifting plate 56 and the second sealing plate 57, causing the second sealing plate 57 to draw air from the connecting cavity 53 and the suction cup 52, thus allowing the suction cup 52 to adhere stably to the tabletop. Pressing the two operating pads 46 against the two operating plates 471 causes air inside the operating block 45 to enter the support cylinder 41 through the one-way valve 491 and the valve. The air entering the support cylinder 41 pushes up the lifting rod 42 through the first sealing plate 43, causing the lifting rod 42 to lift the mounting block 31. Releasing the operating plate 471 causes the spring 47 to return the operating plate 471 to its original position, allowing the operating pad 46 to return to its original position. External air is drawn into the operating block 45 through the air intake one-way valve to refill the support cylinder 41. When the mounting block 31 needs to be lowered, the valve inside the connecting pipe 492 is opened to connect the air inside the support cylinder 41 with the outside, causing the lifting rod 42 to press down the air, which is then discharged through the delivery pipe 49 and the connecting pipe 492. After the height adjustment is completed, the locking block 27 is rotated 90 degrees by the pull rod 26 so that the locking block 27 is aligned with the through hole. At the same time, it is lowered into the through hole by the rebound of the compression spring 281. The clamping plate 22 can then be flipped by the pull plate 25 to assemble the LED package to be tested. After assembly, the clamping plate 22 is reset, and the pull rod 26 is pushed to move the locking block 27 above the pull plate 25. The locking block 27 is then rotated. After block 27 is rotated 90 degrees, the through hole inside the locking block 27 and the pull plate 25 is misaligned, keeping the clamping plate 22 in position. When moving left and right, the first toothed plate 12 is pulled by the fixing block 11, which drives the first damping shaft 14 to rotate. The first damping shaft 14 allows the fixing block 11 to stop at any point when moving left and right, avoiding wobbling. The first toothed plate 12 drives the first ball 131 to slide inside the fixing block 11 through the stabilizing block 13, reducing the generation of other additional resistance. When the first toothed plate 12 moves, it drives the protective shell 16 to move. The protective shell 16 shields the tooth surface of the first toothed plate 12, ensuring the integrity and appearance of the device. When moving back and forth, the support rod 34 is moved by the fixing block 11, which drives the support rod 34 to rotate. The second damping shaft 33 rotates while moving and abutting against the second toothed plate 32. The design of the second damping shaft 33 allows the fixed plate 21 to stop at any point during its forward and backward movement, preventing wobbling and ensuring stability during LED packaging assembly, thus guaranteeing testing efficiency. When the support rod 34 moves, it drives the fourth ball bearing 371 via the support plate 37. Compared to the support plate 37 directly contacting the limiting plate 36, the friction between the fourth ball bearing 371 and the limiting plate 36 is less. Combined with the third ball bearing 35 on the surface of the support rod 34, this minimizes the resistance of the support rod 34 other than that of the second damping shaft 33, allowing the support rod 34 to move solely based on the resistance of the second damping shaft 33 itself, resulting in smoother movement.The operation of the device is completed through the above steps.

[0047] In summary, this LED packaging testing fixture has good stability. By setting up a first moving mechanism 1, a clamping mechanism 2, and a second moving mechanism 3, the LED package to be tested is assembled by the fixed plate 21 and the clamping plate 22. The first moving mechanism 1 and the second moving mechanism 3 move in the front-back, left-right directions. The movement process is stable and can be stopped and positioned at will, which ensures the testing efficiency of LED packages and makes the assembly of LED packages more stable.
