DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1, as Figure 1 and Figure 2 As shown, a light-emitting diode plastic sealing device with an anti-adhesion function includes a device shell 1, support legs 2 are fixedly connected to the four corners of the lower end of the device shell 1, a glue dispensing component 3 is fixedly installed on the rear part of the upper end of the device shell 1, a concave groove 6 is opened at the upper end of the device shell 1, a conveying rotating component 4 is commonly provided on the inner cavity of the device shell 1 and the inner surface of the concave groove 6, and a coating component 5 is commonly provided on the left end, the right end and the upper end of the device shell 1.

[0034] During the implementation of this embodiment, the light-emitting diode installed on the PCB board is placed in the conveying and rotating component 4, and the movement of the conveying and rotating component 4 gradually drives the light-emitting diode on the PCB board to perform a clamping and fixing operation, so that the dust on the outer surface of the light-emitting diode on the PCB board is cleaned by the coating component 5 during the movement of the light-emitting diode on the PCB board. Secondly, the anti-adhesion coating is applied to the upper side of the outer surface of the light-emitting diode, and then the light-emitting diode on the PCB board is rotated under the action of the conveying and rotating component 4, so that the anti-adhesion coating is more evenly distributed under the action of centrifugal force, and then the anti-adhesion coating applied on the outer surface is blown again by the coating component 5 so that the anti-adhesion coating can be cured, and finally the light-emitting diode on the PCB board is plastic-sealed by the glue dispensing component 3.

[0035] The above-mentioned dispensing component 3 is a mature plastic sealing device in the prior art, and is a mature plastic sealing means in the prior art. This scheme uses it to perform plastic sealing operations on the light-emitting diodes on the PCB board, and its structure and principle will not be explained again.

[0036] The anti-adhesion coating mentioned above is composed of a base resin, an additive, an anti-adhesion agent, a curing agent and a solvent. In this solution, the anti-adhesion coating is applied to the light-emitting diode on the PCB board, so that the light-emitting diode will not be bonded to other electronic components and will not affect the use of the light-emitting diode.

[0037] Specifically, in order to realize the adsorption and rotation of the light-emitting diode on the PCB board, refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the conveying and rotating assembly 4 includes a dual-axis motor 41 fixedly mounted on the front left end of the device housing 1, and a rectangular hole 42 connected to the inner surface of the device housing 1 is symmetrically opened on the inner surface of the concave groove 6. A conveying mechanism 43 is provided in the inner cavity of the device housing 1, and a clamping mechanism 44 is symmetrically provided on the conveying mechanism 43. An adsorption mechanism 45 is provided on the front side of the lower part of the inner surface of the device housing 1, a suction mechanism 46 is provided on the right side of the lower part of the inner surface of the device housing 1, and a rotating mechanism 47 is provided on the front left end of the device housing 1.

[0038] For further information, see Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9In this embodiment, the clamping mechanism 44 includes a fixed block 441 fixedly connected to the right end of the slider 434, a rectangular rod 442 is slidably connected to the inner surface of the fixed block 441, a clamping block 443 is fixedly connected to the right end of the rectangular rod 442, a spring 444 is sleeved on the outer surface of the rectangular rod 442, and the two ends of the spring 444 are respectively fixedly connected to the left end of the fixed block 441 and one side of the rectangular rod 442, a ball 445 is arranged on the inner surface of the rectangular rod 442, and an extrusion plate 446 is symmetrically fixedly connected to the inner surface of the concave groove 6.

[0039] For further information, see Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the conveying mechanism 43 includes a rotating rod 431 that passes through the right end of the device housing 1 symmetrically and extends to the left end of the device housing 1 for rotation. The left end of the rotating rod 431 located at the front is fixedly connected to the output end of the right end of the dual-axis motor 41. The outer surfaces of the two rotating rods 431 are symmetrically fixedly connected with transmission wheels 432. The outer surfaces of the transmission wheels 432 on the same side are both wrapped with cables 433. The outer surfaces of the two cables 433 are fixedly connected with sliders 434 that are slidably connected to the inner surface of the rectangular hole 42. The rear parts of the lower ends of the two sliders 434 are fixedly connected with electromagnetic blocks 435.

[0040] During the implementation process, the light-emitting diode on the PCB board is placed together with the PCB board on the clamping block 443, so that the PCB board and the light-emitting diode are initially placed. At this time, the right end output end of the dual-axis motor 41 is started to drive the rotating rod 431 to rotate, thereby driving the transmission wheel 432 on the rotating rod 431 to rotate. At the same time, since the cable 433 and the transmission wheel 432 are wound and connected, the rotation of the transmission wheel 432 drives the cable 433 to move backward, thereby driving the slider 434 to move backward, and at the same time drives the clamping The mechanism 44 moves backward, and when the ball 445 contacts the outer surface of the extrusion plate 446, since the extrusion plate 446 is concave, the ball 445 squeezes and pushes the rectangular rod 442 to slide on the inner surface of the fixing block 441, so that the two clamping blocks 443 approach each other to the middle, so that the light-emitting diode on the PCB board is clamped and fixed. At the same time, the ball 445 squeezes and pushes the rectangular rod 442, so that the spring 444 is in a compressed state, so that the PCB board and the light-emitting diode placed on the clamping block 443 can be clamped and fixed.

[0041] For further information, see Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6, Figure 7 , Figure 8 and Fig. 9 In this embodiment, the adsorption mechanism 45 includes a guide rail 451 fixedly connected to the middle side of the lower part of the inner surface of the device shell 1, and a limiting groove 452 is symmetrically provided on the upper part of the inner surface of the device shell 1. A circular hole plate 453 is slidably connected to the inner surfaces of the two limiting grooves 452. A round rod 455 is movably connected to the inner surface of the circular hole plate 453. An iron block 454 is symmetrically fixedly connected to the rear part of the left end and the rear part of the right end of the circular hole plate 453. A round block rod 456 is rotatably connected to the inner surface of the circular rod 455. A plurality of ventilation holes 458 are arranged in an annular manner in the middle part of the outer surface of the circular rod 455. A hollow circular ring 457 is rotatably connected to the outer surface of the circular rod 455 at the ventilation hole 458. A telescopic rod 459 fixedly connected to the lower end of the circular hole plate 453 is fixedly connected to the outer surface of the hollow circular ring 457, and a suction cup 4510 is fixedly connected to the upper end of the circular rod 455.

[0042] During the implementation process, under the action of the electromagnetic block 435, the electromagnetic block 435 can absorb the iron block 454 on the circular hole plate 453, so that the slider 434 drives the circular hole plate 453 to slide on the inner surface of the limit groove 452 during the backward movement, and then drives the round rod 455 to move backward, so that the round block rod 456 on the round rod 455 moves on the lower part of the inner surface of the guide rail 451. Since the height of the inner surface of the guide rail 451 is raised from front to back in a step-by-step manner, the round block rod 456 slides on the inner surface of the guide rail 451, while pushing the round rod 455 to move to the first step. At this time, the upper end of the suction cup 4510 at the upper end of the round rod 455 can be tightly attached to the PCB board.

[0043] The circular hole plate 453 and the round rod 455 are movably connected, and the round rod 455 only needs to be able to slide and rotate on the inner surface of the circular hole plate 453.

[0044] In the above-mentioned suction cup 4510, the upper end height is lower than the lower end height of the PCB board in the initial state.

[0045] The hollow ring 457 is rotatably connected to the outer surface of the round rod 455 and is still in a sealed state.

[0046] For further information, see Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9In this embodiment, the suction mechanism 46 includes four support plates 461 fixedly connected to the right side of the lower inner surface of the device shell 1, and the upper ends of the four support plates 461 are commonly fixedly connected with a circular groove rectangular block 462, and the inner surface of the circular groove rectangular block 462 is slidably connected with a piston 463, and the right part of the outer surface of the front rotating rod 1 431 is fixedly connected with a retracting wheel 464, and the outer surface of the retracting wheel 464 is wound with a pull rope 465 fixedly connected to the middle part of the rear end of the piston 463, and the front part of the inner surface of the circular groove rectangular block 462 is fixedly connected with a spring 2 466 fixedly connected to the front end of the piston 463, and the upper end of the circular groove rectangular block 462 is provided with an air outlet hole 467 connected to the inner surface of the circular groove rectangular block 462, and the lower part of the front end and the lower part of the rear end of the circular groove rectangular block 462 is symmetrically fixedly installed with a fixed pulley 468, and the front side of the upper inner surface of the circular groove rectangular block 462 penetrates and extends to the inner surface of the hollow ring 457 and is fixedly connected with a ventilation hose 469.

[0047] During the implementation process, the rotation of the rotating rod 431 will drive the retractable wheel 464 to rotate. Under the action of the winding connection, the retractable wheel 464 winds the pull rope 465, and then pulls the piston 463 to move backward on the inner surface of the circular groove rectangular block 462, so that the piston 463 can continuously absorb the air in the hollow ring 457 through the ventilation hose 469. Since the hollow ring 457 is connected to the inner surface of the round rod 455 through the ventilation hole 458, the piston 463 can absorb the air in the suction cup 4510, so that the suction cup 4510 is in a negative pressure state, and the suction cup 4510 can adsorb and fix the PVB board and the light-emitting diode.

[0048] For further information, see Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the rotating mechanism 47 includes a rotating rod 471 fixedly connected to the left output end of the dual-axis motor 41 through a coupling, the right part of the outer surface of the rotating rod 471 is fixedly connected to a one-way bearing 473, the left end of the device housing 1 penetrates and extends to the left part of the inner surface of the device housing 1 and is rotatably connected to a transmission rod 474, the left part of the outer surface of the transmission rod 474 and the outer surface of the one-way bearing 473 are jointly fixedly connected to a pulley group 472, the lower part of the inner surface of the device housing 1 is rotatably connected to a transmission rod 476, the right part of the outer surface of the transmission rod 474 and the middle part of the outer surface of the transmission rod 476 are jointly fixedly connected to a gear group 475, the upper part of the outer surface of the transmission rod 476 is fixedly connected to a gear 477, and the lower part of the outer surface of the round rod 455 is fixedly connected to a gear 478 meshing with the gear 477.

[0049] During the implementation process, the adsorption mechanism 45 and the clamping mechanism 44 move with the conveying mechanism 43. When the round block rod 456 moves to the second step on the inner surface of the guide rail 451, the ball 445 will move to the concave part of the extrusion plate 446 in advance at a set distance. At this time, the two clamping blocks 443 will move away from each other under the compression reaction of the spring 1 444, so that the PVB board and the light-emitting diode can only be adsorbed and fixed by the suction cup 4510, and the position height of the PVB board and the light-emitting diode is changed. At the same time, the gear 1 477 is meshed with the gear 2 478. At this time, the right end output end of the dual-axis motor 41 is closed, and the left end output end of the dual-axis motor 41 is started, so that the rotating rod 2 471 rotates forward, and then through the one-way bearing Under the action of 473, pulley group 1 472 is driven to transmit, so that transmission rod 1 474 rotates, and under the action of gear group 475, transmission rod 2 476 is driven to rotate, and then gear 1 477 is driven to rotate, so that gear 1 477 drives round rod 455 to rotate on the inner surface of circular hole plate 453. At the same time, under the limiting action of telescopic rod 459, hollow ring 457 is rotated on the outer surface of round rod 455, so as to avoid the ventilation hose 469 from being entangled. With the rotation of round rod 455, the PVB board and light-emitting diode adsorbed on suction cup 4510 are driven to rotate, so that the anti-adhesion coating applied on the outer surface of light-emitting diode can be evenly distributed by the centrifugal force generated by the rotation.

[0050] Secondly, after the suction cup 4510 has finished rotating, the right end output end of the dual-axis motor 41 is started to drive the conveying mechanism 43 to move backward again. Under the action of the electromagnetic block 435 and the iron block 454, the adsorption mechanism 45 will still be driven to move backward. Under the action of the guide rail 451, the height of the PVB board and the light-emitting diode adsorbed on the suction cup 4510 gradually decreases to the initial height of the suction cup 4510. At this time, the lower end of the PVB board and the light-emitting diode is still on the clamping block 443. At this time, the piston 463 moves to the position of the air outlet 467, and the circular groove rectangular block 462 The inner cavity no longer generates negative pressure, so that the suction cup 4510 can no longer adsorb the PVB board and the light-emitting diode. At the same time, under the action of the extrusion plate 446, the clamping mechanism 44 once again clamps and fixes the PVB board and the light-emitting diode. When the circular hole plate 453 moves to the rearmost of the inner surface of the limiting groove 452, the circular hole plate 453 is blocked. At this time, the electromagnetic block 435 is turned off, so that the electromagnetic block 435 no longer generates magnetic force, and the circular hole plate 453 no longer moves backward with the conveying mechanism 43, so as not to affect the subsequent plastic sealing operation.

[0051] The electromagnetic block 435 mentioned above is a mature magnetic attraction component in the prior art. The present solution utilizes the fact that when current passes through a wire, the movement of electrons on the wire forms a magnetic field surrounding the wire, and this magnetic field can attract magnetic objects, such as iron or steel.

[0052] The one-way bearing 473 mentioned above is a mature one-way rotating part in the prior art. This solution utilizes its function of being able to rotate freely in one direction and being locked in the other direction, and its structure and principle will not be elaborated again.

[0053] The dual-axis motor 41 mentioned above is a mature driving technology device in the prior art, and is a mature driving technology means in the prior art. This solution utilizes it to rotate independently on both sides, and the number of positive and negative rotations on both sides can be adjusted and controlled separately, and it can stop in time after rotating to the set number of circles.

[0054] The pulley assembly 472 mentioned above is composed of two rollers and a belt.

[0055] The gear set 475 mentioned above is composed of two bevel gears with an angle of 90 degrees.

[0056] Embodiment 2: Based on Embodiment 1, this embodiment further includes a coating component 5 for coating the anti-adhesion coating on the outer surface of the light-emitting diode, so as to achieve the purpose of coating the anti-adhesion coating on the outer surface of the light-emitting diode.

[0057] Specifically, in order to apply an anti-adhesion coating to the outer surface of the light-emitting diode, refer to Figure 2 , Figure 3 , Fig.10 , Fig.11 and Fig.12 In this embodiment, the coating component 5 includes a circular cover 51 fixedly connected to the left end of the device housing 1, and a card slot 54 is symmetrically provided at the upper end of the device housing 1. A rectangular frame 55 is commonly clamped on the inner surfaces of the two card slots 54, and an inclined frame 56 is fixedly connected to the lower part of the inner surface of the rectangular frame 55. A blower mechanism 52 is provided on the inner surface of the circular cover 51, and a coating mechanism 53 is commonly provided on the right end and the upper end of the device housing 1.

[0058] For further information, see Figure 2 , Figure 3 , Figure 5 , Fig.10 , Fig.11 and Fig.12 In this embodiment, the hair dryer mechanism 52 includes a rotating rod three 521 rotatably connected to the inner surface of the circular cover 51, the right part of the outer surface of the rotating rod two 471 and the left part of the outer surface of the rotating rod three 521 are fixedly connected with a pulley group two 522, the right part of the outer surface of the rotating rod three 521 is fixedly connected with a fan blade 523, the upper part of the inner surface of the circular cover 51 is located on the right side of the fan blade 523 and extends to the upper part of the outer surface of the circular cover 51, and an exhaust pipe 524 is fixedly connected, and an electromagnetic valve 525 is fixedly installed at the intersection of the outer surfaces of the exhaust pipe 524.

[0059] During the implementation process, when the light-emitting diode on the PCB board is moving backward, the right end output end of the dual-axis motor 41 is started to drive the rotating rod 2 471 to rotate backward. Under the transmission action of the pulley group 2 522, the fan blade 523 on the rotating rod 3 521 rotates, and then the air is sucked into the circular cover 51 through the filter net on the circular cover 51, and then enters the exhaust pipe 524. Under the action of the solenoid valve 525, the wind can only be discharged through the exhaust pipe 524 at the front, so as to clean the dust attached to the outer surface of the light-emitting diode on the PCB board.

[0060] The belt pulley set 2 522 mentioned above is composed of two rollers and a belt.

[0061] For further information, see Figure 2 , Figure 3 , Figure 5 , Fig.10 , Fig.11 and Fig.12 In this embodiment, the smearing mechanism 53 includes a placement box 531 fixedly connected to the right end of the device housing 1, a fixing plate 532 is fixedly connected to the left and right parts of the upper end of the device housing 1, a sponge block 533 is pasted on the inner surface of the fixing plate 532, a connecting pipe 534 is fixedly connected to the upper part of the inner surface of the placement box 531 and extends to the right part of the inner surface of the fixing plate 532, and a water pump 535 is fixedly connected to the lower end of the connecting pipe 534.

[0062] During the implementation process, the water pump 535 is started so that the water pump 535 draws the anti-adhesion coating in the placement box 531 into the connecting pipe 534, so that the connecting pipe 534 can transport the anti-adhesion coating to the sponge block 533. When the light-emitting diode on the PCB board passes through, the light-emitting diode on the PCB board squeezes the sponge block 533, so that the sponge block 533 can apply the anti-adhesion coating on the outer surface of the light-emitting diode, and then perform the coating operation. At the same time, with the cooperation of the rotating mechanism 47, the applied anti-adhesion coating can be evenly distributed on the outer surface of the light-emitting diode under the action of centrifugal force. The anti-adhesion coating thrown out after rotation can be collected by the rectangular frame 55 and the inclined frame 56 to avoid splashing of the anti-adhesion coating. At the same time, the poor luminous efficiency of the light-emitting diode caused by uneven thickness can be effectively avoided.

[0063] Secondly, the anti-sticking coating on the outer surface of the rotated LED can, under the action of the solenoid valve 525, allow the wind in the circular cover 51 to enter the exhaust pipe 524 at the rear, thereby curing the anti-sticking coating applied to the LED and accelerating the curing of the anti-sticking coating.

[0064] The sponge block 533 mentioned above can be used to absorb the liquid of the anti-adhesive coating.

[0065] The solenoid valve 525 mentioned above is a mature control means and a mature control device in the prior art. This solution uses it to control the flow direction of air, and its structure and principle will not be explained again.

[0066] Working process: When in use, the light-emitting diode on the PCB board is placed together with the PCB board on the clamping block 443 in the clamping mechanism 44. At this time, the right end output end of the dual-axis motor 41 is started to drive the conveying mechanism 43 to move, so that the clamping mechanism 44 clamps and fixes the PCB board and the light-emitting diode, and when moving backward, the dust attached to the outer surface of the light-emitting diode is cleaned by the blower mechanism 52, and the PCB board and the light-emitting diode are adsorbed and fixed with the cooperation of the adsorption mechanism 45 and the suction mechanism 46, and the anti-adhesion coating is applied to the outer surface of the light-emitting diode under the action of the coating mechanism 53, and the light-emitting diode is rotated under the action of the rotating mechanism 47. The centrifugal force generated by the rotation allows the applied anti-adhesion coating to be evenly attached to the outer surface of the light-emitting diode.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
