Description

Technical Field

[0001] The invention relates to the technical field of COB light source packaging, and in particular to a COB light source packaging device with an airtightness detection function. Background Art

[0002] COB light source packaging stands for chip on board packaging, which is an advanced electronic packaging process. It involves covering the top of the LED light-emitting chip with a layer of polymer material or other protective material for packaging to protect the LED light-emitting chip from environmental influences and improve heat dissipation capabilities. Since the curing rate of epoxy resin is affected by temperature, too low a temperature will cause the curing reaction rate of the epoxy resin dripped on the LED chip to decrease, thereby extending the curing time of the epoxy resin and causing insufficient curing reaction of the epoxy resin, which will prevent the epoxy resin from being completely cured and affect its light transmission performance. In addition, the incompletely cured epoxy resin will change color over time, causing the color consistency of the LED product to deteriorate and affecting the overall visual effect of the product. Summary of the invention

[0003] The object of the present invention is to provide a COB light source packaging device with an airtightness detection function to solve the problems mentioned in the above process.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The air cylinder is connected to the lower air cavity through the second air guide pipe, so that the mechanical arm and the piston assembly move in opposite directions. When the piston assembly grabs the workpiece and descends, the guide rod will drive the rotating plate to rotate through the rotating cylinder. At this time, the two opening and closing plates will be closed, and the upper air cavity is in a sealed state. During the descent of the piston assembly, the piston plate passes the gas in the booster cylinder into the upper air cavity, causing the air pressure inside the upper air cavity to increase. At the same time, the heat generated by the electric heating wire will be transferred to the upper air cavity, thereby baking the epoxy resin on the workpiece, and the increase in the temperature inside the upper air cavity further increases the air pressure in the upper air cavity, using the high temperature and high pressure environment to increase the reaction activity of epoxy resin curing, thereby improving the curing rate of epoxy resin, and using the pressure in the upper air cavity to further promote the complete curing of epoxy resin, thereby ensuring the light transmittance of the cured epoxy resin, avoiding the change of the color of the epoxy resin, and improving the overall visual effect of the workpiece during use; 2. The workpiece is positioned by two springs and a reset plate, so that the drip nozzle on the robot arm can accurately drip epoxy resin on the upper surface of the workpiece, thereby improving the packaging quality of the workpiece. At the same time, the piston assembly can grab the positioned workpiece, avoiding manual operation, with a high degree of automation and improved production efficiency; 3. Push the moving plate and the workpiece on it to the receiving plate through the discharging plate, and use the moving plate to push the horn rack, so that the receiving plate gradually moves away from the moving plate. At this time, the workpiece on the moving plate will fall on the receiving plate. When the moving plate is separated from the locking hook, the ultrasonic transmitter and the ultrasonic receiver are used to scan the workpiece, so as to detect the air tightness of the workpiece and the tiny cracks on the workpiece, thereby improving the accuracy of the air tightness detection of the workpiece; 4. The workpiece is limited by moving ring 2 so that the workpiece will not be shaken by the ultrasonic wave, further improving the accuracy of the workpiece air tightness test results.

[0029] The sealing assembly 28 includes a rotating plate 281, a rotating cylinder 282 arranged on the rotating plate 281, and a guide rod 261 symmetrically arranged on the piston plate 26. A rotating groove is opened at the lower end of the conveying plate 11, and the rotating plate 281 is rotatably installed in the rotating groove. The curing cylinder 21 is rotatably connected to the rotating plate 281, and the rotating cylinder 282 is fixedly installed on the rotating plate 281. Spiral grooves are symmetrically opened on the inner wall of the rotating cylinder 282, and a linear groove 1 is symmetrically opened on the outer wall of the curing cylinder 21. A linear rail 1 is fixedly installed on the side where the two guide rods 261 are close to each other, and the linear rail 1 is slidably installed in the linear groove 1. A guide block 1 is fixedly installed on the side where the two guide rods 261 are away from each other, and the guide block 1 is slidably installed in the spiral groove.

[0030] The sealing assembly 28 also includes two closing plates 283, and guide grooves 284 are symmetrically opened on the rotating plate 281. The ends of the two closing plates 283 that are close to each other are provided with chamfers, and the chamfers on the two closing plates 283 are adapted to each other. A rotating groove is opened in the middle area of ​​the rotating plate 281, and the rotating groove is coaxial with the discharge port. The inner diameter of the rotating groove is equal to or slightly larger than the maximum outer diameter of the workpiece. A guide block 2 is fixedly installed on the lower surface of the closing plate 283, and the guide block 2 is slidably set in the guide groove 284.

[0031] The piston assembly 24 includes a piston block 241, a moving ring 242 arranged on the piston block 241, and a push rod 243 arranged in an array in the piston block 241. The piston block 241 is provided with an elastic groove 1, and the moving ring 242 is slidably arranged in the elastic groove 1. A spring 1 is fixedly installed in the elastic groove 1, and the spring 1 is fixedly connected to the moving ring 242. The inner wall of the moving ring 242 is provided with a slope-shaped structure. An elastic groove 2 is arranged in an array in the piston block 241, and the push rod 1 243 is slidably arranged in the elastic groove 2. A spring 3 is fixedly installed at the bottom of the elastic groove 2, and the spring 3 is connected to the push rod 1 2 43 is fixedly connected, the elastic force of spring two is smaller than the elastic force of spring one, so that in the initial state, spring one pushes moving ring one 242, at which time moving ring one 242 will push push rod one 243, and spring two is deformed and compressed, and push rod one 243 is guided by the slope-like structure of moving ring one 242, so that push rod one 243 shrinks into elastic groove two, and the elastic force of spring two is larger than the elastic force of spring three, and when spring two pushes push rod one 243 to extend out of elastic groove two, push rod one 243 will push push rod two, and spring three will be deformed and compressed, and push rod two shrinks into elastic groove three.

[0032] During use, the positioning component 3 first positions the workpiece in the conveying plate 11, so that the workpiece in the conveying plate 11 is limited to the discharge port. At this time, under the elastic force of the spring three, the push rod two will extend from the elastic groove three. At this time, the workpiece moved to the discharge port will be supported by the push rod two. Then the robot arm 12 drives the bottom injection nozzle to move synchronously until it gradually approaches the workpiece. When the drip nozzle descends to an appropriate position, the drip nozzle drips the colloid epoxy resin on the upper surface of the workpiece. When the drip nozzle completes the dripping work on the workpiece, the robot arm 12 drives the drip nozzle to gradually rise and reset. When the mechanical arm 12 drives the drip nozzle to descend, the synchronous plate 13 will move synchronously with the mechanical arm 12 to descend, so that the gas plug 14 gradually moves toward the direction of the gas cylinder 15. At this time, the gas in the gas cylinder 15 will be introduced into the lower gas cavity through the second gas guide pipe. At this time, the gas pressure in the lower gas cavity gradually increases, causing the piston assembly 24 to gradually rise and move toward the direction of the discharge port; At this time, the piston rod 25 and the piston plate 26 will move synchronously with the piston assembly 24, causing the guide plate to move linearly along the line groove 1, and then the guide block 1 will slide along the spiral groove. At this time, the rotating cylinder 282 will drive the rotating plate 281 to rotate, and then the guide block will slide along the guide groove 284, and the two closing plates 283 will move away from each other. When the two closing plates 283 are separated, the piston assembly 24 passes through the two closing plates 283 and continues to rise. At this time, the moving ring 1 242 will contact the push rod 2. At this time, the spring 1 is deformed and compressed, and the moving ring 1 242 shrinks into the elastic groove 1. When the moving ring 1 242 shrinks to separate from the push rod 1 243, the push rod 1 243 will extend from the elastic groove 2 under the elastic force of the spring 2. At this time, the push rod 1 243 will push the push rod 2. At this time, the spring 3 is deformed and compressed, and the push rod 2 shrinks into the elastic groove 3. When the push rod 2 shrinks to separate from the moving ring 1 242, the spring 1 will push the moving ring 1 242 to extend from the elastic groove 1 and push the push rod 1 243 and the push rod 2 at the same time, so that the springs 2 and 3 are deformed and compressed. At this time, the workpiece positioned by the positioning component 3 will contact the piston block 241. When the robot arm 12 starts to rise, the gas in the lower air cavity re-enters the air cylinder 15 through the air guide pipe 2. At this time, the piston assembly 24 drives the workpiece to synchronously descend into the curing cylinder 21. When the workpiece and the piston assembly 24 descend to the lower ends of the two closing plates 283, the two closing plates 283 are closed. During the descent of the piston assembly 24, the piston plate 26 guides the gas in the booster cylinder 27 into the upper air cavity through the air guide pipe 1. At this time, the gas pressure in the upper air cavity increases. At the same time, the power supply is electrically connected to the heating wire 22, so that the heat generated by the heating wire 22 is transferred to the upper air cavity. At this time, the gas in the upper air cavity expands as it gets hotter, thereby increasing the gas pressure in the upper air cavity. By placing the colloidal epoxy resin on the workpiece in a high temperature and high pressure environment, the curing rate of the colloidal epoxy resin is promoted.

[0033] Example 2 Reference Figure 1-6, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: The positioning component 3 includes a reset plate 31, a spring piece 32 symmetrically arranged in the conveying plate 11, and a limit block 33 symmetrically arranged in the conveying plate 11. The reset plate 31 is slidably installed in the feed trough. A notch is provided at one end of the reset plate 31. The notch and the outer diameter of the workpiece are adapted to each other. A plurality of rollers are rotatably installed at the notch to reduce friction. A spring piece 2 is symmetrically installed at the end of the reset plate 31 away from the notch. The end of the spring piece 2 away from the reset plate 31 is fixedly connected to the bottom of the feed trough. The spring piece 1 32 is in a V-shaped structure. The end of the spring piece 1 32 close to the reset plate 31 is rotatably connected to the wall of the feed trough. The spring piece 1 32 is symmetrically installed at the end of the reset plate 31 away from the notch. One end can slide along the wall of the feed trough, and the limit block 33 is set on the wall of the feed trough, and in the initial state, under the elastic force of the spring piece 32 itself, the spring piece 32 fits with the limit block 33, and a push plate is slidably installed in the feed trough, and the end of the push plate away from the conveying plate 11 is connected to the discharge plate, and the end of the discharge plate away from the push plate is fixedly connected to the moving plate 23, and a rack and a linear rail three are fixedly installed at the bottom of the discharge plate, and a support plate is fixedly installed on the base plate 1, and a motor and a support block are fixedly installed on the support plate. The motor output shaft is coaxially connected with a gear, and the gear is meshed with the rack. A slider is fixedly installed on the support block, and the slider is slidably installed on the linear rail three.

[0034] During use, when the epoxy resin on the workpiece in the upper air cavity is cured, the second workpiece to be encapsulated by dripping epoxy resin is placed into the feed trough from the feed port, and the motor is started. At this time, the motor output shaft will drive the gear to rotate, and then the gear drive drives the discharge plate to move toward the moving plate 23 through the rack, and at the same time, the push plate will push the second workpiece to move toward the discharge port; Since the second workpiece will push the spring piece 1 32 during the movement, the end of the spring piece 1 32 close to the limit block 33 will rotate in the direction away from the limit block 33 under the limiting action of the limit block 33, and at the same time, the end of the spring piece 1 32 away from the limit block 33 will slide along the groove wall of the feed groove, and the second workpiece will push the reset plate 31, and the spring piece 2 will be deformed and compressed. When the second workpiece passes through the spring piece 1 32, the spring piece 1 32 and the spring piece 2 will be reset under the action of the rebound force, and then the spring piece 1 32 and the reset plate 31 will push the second workpiece and position it; at the same time, the discharge plate will push the movable plate 23 and the workpiece on the piston assembly 24 to move in the direction of the detection component 4.

[0035] The remaining structures are the same as those of Example 1.

[0036] Example 3 Reference Figure 1-10 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: The detection component 4 includes a receiving plate 41, a movable ring 2 42 arranged on the receiving plate 41, and a horn bracket 43 arranged on the receiving plate 41. A mounting block is fixedly installed on the upper surface of the substrate 1, and a linear rail 2 is installed in an array on the mounting block. A linear groove 2 is arranged in an array on the receiving plate 41. The linear rail 2 is slidably installed in the linear groove 2. An elastic groove 4 is opened in the middle area of ​​the receiving plate 41. The movable ring 2 42 is slidably installed in the elastic groove 4. A spring 4 is fixedly installed at one end of the movable ring 2 42 close to the elastic groove 4, and the other end of the spring 4 is connected to the bottom of the elastic groove 4. A guide part 2 is arranged on the movable ring 2 42, and the guide part 2 is adapted to each other. Key grooves are symmetrically opened on the receiving plate 41, and guide blocks 3 are symmetrically installed on the horn bracket 43. Guide blocks 3 are slidably installed in the key grooves.

[0037] A locking hook 44 is symmetrically arranged on the horn frame 43, a rotating shaft 441 is arranged on the locking hook 44, a trigger rod 1 442 is arranged on the rotating shaft 441, and a trigger rod 2 443 is arranged on the rotating shaft 441. A trigger groove is provided at the end of the locking hook 44 away from the horn frame 43, and the rotating shaft 441 is rotatably installed in the trigger groove. A torsion spring 1 is sleeved at the connection between the rotating shaft 441 and the horn frame 43. Side plates are symmetrically arranged on the horn frame 43, and a connecting plate 2 is installed at one end of the side plate. The end of the locking hook 44 away from the trigger groove is fixedly connected to the connecting plate 2.

[0038] A clamping plate 45 is symmetrically arranged on the receiving plate 41, and a connecting plate 46 is symmetrically arranged on the receiving plate 41. A clamping slot is symmetrically opened on the receiving plate 41. The clamping plate 45 is rotatably installed in the clamping slot. A torsion spring 2 is sleeved at the connection between the clamping plate 45 and the clamping slot. A locking hook 44 passes through the connecting plate 46. A spring 5 is sleeved on the outer side of the locking hook 44. The end of the spring 5 away from the connecting plate 46 is fixedly connected to the connecting plate 2.

[0039] A vertical plate 47 is symmetrically arranged on the substrate 1, an ultrasonic transmitter 48 is arranged on the horn frame 43, and an ultrasonic receiver 49 is arranged on the horn frame 43. The vertical plates 47 are symmetrically arranged on both sides of the horn frame 43, and the side plates are slidably connected to the vertical plates 47. A fixing plate is fixedly installed on the substrate 1, and a display is fixedly installed on the fixing plate. The display is electrically connected to the ultrasonic transmitter 48 and the ultrasonic receiver 49.

[0040] During use, when the moving plate 23 moves toward the detection component 4, the guide portion 1 of the moving plate 23 will contact the guide portion 2 of the moving ring 2 42, and then the spring 4 will deform and compress, and the moving ring 2 42 will shrink into the elastic groove 4; As the moving plate 23 moves, the horn rack 43 will slide linearly along the vertical plate 47 and gradually move away from the receiving plate 41. At this time, the receiving plate 41 will gradually drop and move away from the moving plate 23. At this time, the workpiece on the moving plate 23 will fall onto the receiving plate 41 and be located in the moving ring 2 42. At this time, the spring 5 is deformed and stretched, and the lock hook 44 moves close to the receiving plate 41. Since the moving plate 23 fits the surface of the lock hook 44 and passes through the lock hook 44, the torsion spring 1 is deformed, and the trigger rod 1 442 rotates into the trigger groove. At this time, the trigger rod 2 443 extends out of the trigger groove and is perpendicular to the trigger groove. When the trigger rod 2 443 contacts the card plate 45, the torsion spring 2 is deformed, and the card plate 45 avoids the trigger rod 2 443. When the trigger rod 2 443 passes through and separates from the card plate 45, the card plate 45 is reset under the rebound force of the torsion spring 2. When the motor drives the discharging plate and the moving plate 23 to reset, the driving plate will separate from the horn frame 43, and the horn frame 43 has a tendency to reset under the resilience of the spring 5. At this time, the trigger rod 443 will contact the clamping plate 45, and the clamping plate 45 will limit the trigger rod 443, so that the horn frame 43 cannot be reset at this time; When the movable plate 23 is separated from the trigger rod 1 442 on the locking hook 44, the movable plate 23 is just misaligned with the workpiece dropped on the receiving plate 41. At this time, the rotating shaft 441 is reset under the rebound force of the torsion spring 1, and the trigger rod 2 443 can be rotated to the trigger groove to avoid the clamping plate 45. At this time, the horn rack 43 will be reset under the rebound force of the spring 5. At this time, an ultrasonic wave is emitted by the ultrasonic transmitter 48. The ultrasonic wave emitted by the ultrasonic transmitter 48 toward the workpiece on the receiving plate 41 is refracted by the workpiece and received by the ultrasonic receiver 49. Then, the image data of the workpiece scanned by the ultrasonic wave is displayed in real time on the display, and then the air tightness, tiny cracks and weak points of the workpiece dripped with epoxy resin are detected. Finally, the workpiece after the air tightness test is completed is removed from the receiving plate 41.

[0041] The remaining structure is the same as that of Example 2.
