Description

Technical Field

[0001] The present invention relates to the technical field related to LED packaging, and in particular to a portable LED bracket packaging module. Background Art

[0002] LED bracket, the base of LED lamp bead before packaging. On the basis of LED bracket, fix the chip into it, weld the positive and negative electrodes, and then use packaging glue to package it once. LED bracket is generally made of copper, because copper has good conductivity. It will have leads inside to connect the electrodes inside the LED lamp bead. After the LED lamp bead is packaged, the lamp bead can be removed from the bracket. The copper feet at both ends of the lamp bead become the positive and negative electrodes of the lamp bead, which are used to weld to LED lamps or other LED finished products. LED bracket packaging is an important part of the LED lamp bead manufacturing process, which involves fixing the chip on the bracket and packaging it by dispensing glue.

[0003] Existing glue dispensing packaging, such as the Chinese patent with publication number CN107516707A, discloses a glue dispensing process, step one: dehumidify and remove dust from the LED bracket, and use fluorescent glue to fix the LED chip in the bowl of the LED bracket; step two: fill the fluorescent glue into the glue cylinder of the automatic glue dispensing equipment, set the single glue spraying amount of the glue dispensing nozzle in the automatic glue dispensing equipment according to the bowl of the LED bracket, the glue spraying accuracy is: <0.5%, and the excess air in the glue dispensing nozzle is discharged before each operation. The fluorescent glue in the glue cylinder is replaced every 30 to 35 minutes; step three: use the automatic glue dispensing equipment in step two to apply fluorescent glue to the bowl of the LED bracket; step four: put the LED bracket after glue dispensing into the oven for drying within 8 minutes, the baking temperature is 95-140°C, and the baking time is 10 minutes to 30 minutes; step five: after baking, when the fluorescent powder is formed, the LED glue dispensing process is completed. The present invention has accurate glue quantity control, fast operation, and fewer steps.

[0004] In the above-mentioned technology, the problem of glue quantity is mainly considered, and the blockage problem of the glue dispensing head and the degree of molding of the glue dripping on the LED bracket are not taken into consideration. The existing glue dispensing head is usually cleaned only when the operation is stopped. The blockage that occurs during the operation is difficult to solve in time, resulting in a reduction in the subsequent glue dispensing amount. In order to seal the LED core and the welding wire on the LED bracket, the glue dripping on the LED bracket needs to be spread more evenly on the LED core and the welding wire, so as to fully cure and protect the two. However, the existing glue does not adjust its molding degree after dripping, resulting in a reduction in the protection effect of some positions in the later stage.

[0005] Based on this, there is still room for improvement based on the existing dispensing packaging. Summary of the invention

DETAILED DESCRIPTION

[0032] The following is combined with Figures 1 to 7 This application is described in further detail.

[0033] The embodiment of the present application discloses a portable LED bracket packaging module. The present application performs conveying positioning on the LED bracket and performs glue dispensing packaging on it. During the packaging process, the glue dispensing head is cleaned at intervals to ensure the normal spraying of the glue dispensing head. At the same time, the LED bracket after glue dispensing is vibrated with a high frequency and a small amplitude to evenly shake the glue liquid, thereby improving the packaging effect.

[0034] Reference Figures 1 to 4As shown, a portable LED bracket packaging module disclosed in this embodiment includes a base plate 1, a conveying component 2, a positioning component 3, a placement component 4, a cleaning component 5, a spray component 6, a gantry 7, and a glue dispensing component 8. The base plate 1 is a fixed foundation. The conveying component 2 is installed in the middle of the base plate 1. The LED bracket is conveyed by the conveying component 2. The positioning component 3 is installed on the base plate 1, and the left and right positioning components 3 are respectively located on the left and right sides of the conveying component 2. The LED bracket is positioned and clamped after being conveyed to the specified position by the positioning component 3. The placement component 4 is installed on the positioning component 3 arranged on the left side of the base plate 1. The cleaning component 5 is installed on the positioning component 3 arranged on the right side of the base plate 1. The spray component 6 is installed at the rear end of the base plate 1, and the placement component 4 and the cleaning component 5 are connected with the spray component 6. The gantry 7 is installed on the base plate 1. The glue dispensing component 8 is horizontally movable and slidingly arranged on the gantry 7. The cleaning agent is conveyed to the placement component 4 and the cleaning component 5 by the spray component 6 and then atomized and sprayed out to clean the glue dispensing head of the glue dispensing component 8.

[0035] In the actual packaging process, the LED bracket is cleaned and dried ultrasonically, and the electrode at the bottom of the LED core is expanded after being coated with silver glue. The expanded core is placed on a crystal stinging table, and the core is mounted on the corresponding pad of the bracket with a crystal stinging pen for sintering to solidify the silver glue. An aluminum wire or gold wire welding machine is used to connect the electrode to the LED core as a lead for current injection, and then glue dispensing packaging is performed. The gantry 7 drives the glue dispensing component 8 to move in multiple directions, so that the glue dispensing head on the glue dispensing component 8 is moved to the placement component 4 for sleeve placement, and the cleaning agent is sprayed out from the placement component 4 by the spray component 6 to temporarily clean the placed glue dispensing head, and then the LED bracket is transported to the positioning component 3 through the conveying component 2, and the positioning component 3 is used to position it. The glue dispensing component 8 is clamped and positioned, and the gantry 7 is used to drive the glue dispensing component 8 to move again so as to perform glue dispensing on the LED bracket, thereby sealing and protecting the LED tube core and welding wire on the LED bracket. After the glue dispensing is completed, the gantry 7 is used to drive the glue dispensing component 8 to move to the cleaning component 5, and the positioning component 3 is used to perform high-frequency and small-amplitude vibration to evenly shake the glue on the LED bracket. At the same time, the spray component 6 cooperates with the cleaning component 5 to perform rotational scraping and center-insertion atomization cleaning operations on the glue dispensing head on the glue dispensing component 8, thereby cleaning the glue dispensing head to prevent blockage. Subsequently, the positioning component 3 releases the LED bracket, drives the LED bracket after glue dispensing to be output through the conveying component 2, and transports it to the oven for curing to complete the packaging.

[0036] Reference Figures 5 and 6As shown, the positioning assembly 3 includes a base 31, a movable part 9, a clamping bracket 32, a clamping plate 33, a lifting unit 34, a prompting unit 35, and a vibration unit 36. The base 31 is installed on one side of the bottom plate 1. A movable groove is provided on the side wall of the base 31. A movable block is provided in the movable groove for sliding up and down. The movable block is installed on the side wall of the movable part 9. A clamping bracket 32 ​​is installed on the upper end of the movable part 9. The clamping plate 33 is provided in the sliding groove provided on the side wall of the clamping bracket 32 ​​for sliding up and down. The clamping plate 33 is connected to the lifting unit 34 of the movable part 9. The clamping plate 33 is driven to move up and down by the lifting unit 34. The prompting unit 35 is installed on the upper end surface of the clamping bracket 32. The vibration unit 36 ​​is provided inside the base 31. The clamping bracket 32 ​​is driven to vibrate up and down by the vibration unit 36.

[0037] During the actual clamping and positioning process, the LED bracket is transported to the positioning component 3 through the conveying component 2. At this time, the end (one end) of the LED bracket is located between the clamping bracket 32 ​​and the clamping plate 33. The clamping plate 33 is then driven up by the lifting unit 34, and one end of the LED bracket is clamped by the clamping plate 33 and the clamping bracket 32 ​​(similarly, the other end of the LED bracket is also clamped). After clamping, the prompt unit 35 lights up to confirm that the clamping is completed, and then the glue dispensing operation is performed. After the glue dispensing operation is completed, the clamped LED bracket is driven to vibrate with high frequency and small amplitude through the vibration unit 36.

[0038] Reference Figure 6 As shown, in order to ensure that the clamping is in place, the present application further improves the structure of the prompt unit 35, and its specific structure is as follows: the prompt unit 35 includes an insulating shell 351, and the insulating shell 351 is installed on the upper end surface of the clamping bracket 32. The prompt light 352, power supply, and conductive member 353 arranged inside the insulating shell 351 are electrically connected. The conductive head 354 corresponding to the position of the conductive member 353 is installed on the insulating slide rod. The number of the conductive heads 354 is two, and the insulating slide rod is slidably arranged up and down on the clamping bracket 32; the conductive member 353 is composed of two L-shaped members, and the two L-shaped members are arranged symmetrically on the left and right.

[0039] During the actual clamping process, the clamping plate 33 rises after being driven by the lifting unit 34, and the end of the LED bracket is lifted synchronously. When the clamping is completed correctly, the conductive head 354 on the insulating slide rod contacts the conductive part 353, so that the prompt unit 35 forms a passage state. At this time, the prompt light 352 lights up to prompt, otherwise it is determined that there is a problem with the clamping.

[0040] Reference Figures 5 and 6As shown, the vibration unit 36 ​​includes a motor 361, a cam 362, a vibration piece 363 and a vibration frame 364. The motor 361 is built into the base 31, and the cam 362 is installed on the output shaft of the motor 361. The vibration piece 363 used for extrusion and cooperation with the cam 362 is slid up and down in the base 31, and the vibration frame 364 fitted with the upper end of the vibration piece 363 is fixedly installed on the side wall of the clamping bracket 32.

[0041] During the actual vibration process, the motor 361 drives the cam 362 to rotate, and according to the cam principle, the vibration member 363 drives the unlocked vibration frame 364 to vibrate up and down at high frequency, thereby vibrating the clamped LED bracket with high frequency and small amplitude.

[0042] Reference Figure 6 As shown, before the dispensing head dispenses glue, it is moved to the placement component 4 for simple cleaning. The specific structure of the placement component 4 is as follows: the placement component 4 includes a connecting piece 41, and the connecting piece 41 is installed on the side wall of the clamping bracket 32 ​​arranged on the left side of the base plate 1. A placement piece 42 is installed on the upper end of the connecting piece 41; a built-in cavity 43 is opened at the upper end of the placement piece 42, and a diversion cavity 44 is opened at the lower half of the placement piece 42. The middle lower end of the diversion cavity 44 is connected to a blocking plate 45 through a telescopic rod. The interior of the telescopic rod is an elastic structure that always keeps the blocking plate 45 pushing downward. The blocking plate 45 in the initial position temporarily blocks the connecting cavity opened in the connecting piece 41, and the connecting cavity, the diversion cavity 44 and the atomization hole opened on the side wall of the built-in cavity 43 are connected.

[0043] In the actual operation process, since the connecting cavity 592 of the L-shaped structure is in a blocked state at this time, the cleaning agent can only be delivered to the connecting cavity through the spray assembly 6, and then the blocking plate 45 is lifted up and delivered to the diversion cavity 44 and then sprayed out from the atomization hole, thereby performing high-pressure atomization cleaning on the outer surface of the dispensing head.

[0044] Reference Figure 5 , Figure 7As shown, after the dispensing head of the dispensing component 8 has finished dispensing, glue remains on its head. The present application uses a cleaning component 5 to clean the residual glue. The specific structure of the cleaning component 5 is as follows: the cleaning component 5 includes a built-in shell 51, a guide frame 52, a connecting seat 53, an electric turntable 54, a cleaning head 55, an insertion head 56, an extrusion piece 57, an extrusion locking piece 58, a vibration group 59, and a contact head 60. The built-in shell 51 is installed on the clamping bracket 32 ​​arranged on the right side of the base plate 1, and the built-in shell 51 is provided with a guide frame 52. The vibration frame 364 arranged on the right side is slidably arranged on the guide frame 52, and the vibration frame 364 is elastically connected to the guide frame 52. The connecting seat 53 is installed on the built-in shell 51, the upper end of the connecting seat 53 is connected to the cleaning head 55 through an electric turntable 54, the insertion head 56 is slidably arranged at the bottom center position of the connecting seat 53, the extrusion piece 57 is installed on the left side of the lower end of the insertion head 56, and the extrusion locking piece 58 used in conjunction with the extrusion piece 57 is horizontally slidably arranged in the built-in cavity 43 opened in the built-in shell 51, and the position between the built-in shell 51 and the vibration frame 364 is temporarily locked by the extrusion locking piece 58, the vibration group 59 is slidably arranged in the through groove opened in the built-in shell 51, and the contact head 60 corresponding to the position of the vibration group 59 is installed on the vibration frame 364 arranged on the right side; wiping blocks are evenly arranged on the side wall of the inner cavity of the cleaning head 55 along its circumference.

[0045] During the actual cleaning process, the dispensing head after dispensing is moved and placed inside the cleaning head 55. The dispensing head is in a descending state before being placed. The descent of the dispensing head drives the insertion head 56 to descend, and the synchronously descending extrusion member 57 squeezes the extrusion locking member 58 to make it move horizontally to the right, thereby unlocking the position between the built-in shell 51 and the vibration frame 364, and the descending insertion head 56 is locked with the vibration group 59. Subsequently, the vibration unit 36 ​​drives the vibration frame 364 to vibrate up and down, so that the glue on the clamped LED bracket is vibrated evenly, and the vibration frame 364 that vibrates up and down squeezes the vibration group 59 to move up and down, so that the upper end of the insertion head 56 intermittently penetrates into the nozzle of the dispensing head, thereby performing high-pressure atomization on the interior, thereby achieving the purpose of cleaning and preventing blockage. At the same time, the cleaning head 55 is driven by the electric turntable 54 to rotate horizontally, and the residual liquid around the head of the dispensing head is wiped by the wiping block.

[0046] Reference Figure 7As shown, when the LED bracket is not glued, the position between the built-in shell 51 and the vibration frame 364 is locked by squeezing the locking piece 58, ensuring that the LED bracket will not shake up and down when being glued. After the subsequent glue is completed, the position between the built-in shell 51 and the vibration frame 364 can be unlocked by squeezing the insertion head 56, the extrusion piece 57, and the extrusion locking piece 58. The specific structure of the insertion head 56 and the extrusion locking piece 58 is as follows: the insertion head 56 includes a sliding cylinder 561, a sealing cover 562, a plug-in 563, an alignment head 564, a snap-on groove 565, and a sliding plate 566. The sliding cylinder 561 is slidably arranged in the center groove opened in the center of the connecting seat 53. The sliding cylinder 561 is elastically connected to the center groove. The sealing cover 562 is installed at the upper end of the sliding cylinder 561, and the plug-in 563 is slidably arranged inside the sliding cylinder 561. The upper end of the plug-in 563 is a pointed structure, which is convenient for entry. The side wall of the plug-in 563 close to the upper end is evenly provided with spray holes along its circumference, and the spray holes are gradually inclined downward from the inside to the outside. When the plug-in 563 penetrates into the inside of the dispensing head nozzle, the detergent is sprayed out through the spray hole in a high-pressure atomization manner to clean the inner wall of the nozzle, thereby preventing blockage. The alignment head 564 is installed at the lower end of the plug-in 563, and a clamping groove 565 is provided on the left side wall of the alignment head 564. The interior of the alignment head 564, the interior of the plug-in 563 and the spray hole are connected. The sliding plate 566 is installed at the lower end of the sliding cylinder 561, and an extrusion piece 57 is installed on the lower side of the left end of the sliding plate 566.

[0047] Reference Figure 7 As shown, the extrusion locking member 58 includes a snap-fit ​​member 581, which is horizontally slidably arranged in the built-in cavity 43, and the snap-fit ​​member 581 and the built-in cavity 43 are elastically connected. A guide plate 582 is installed at the upper end of the snap-fit ​​member 581, and the guide plate 582 is a structure that gradually tilts upward from left to right, thereby reducing the difficulty of extrusion. A contact block 583 is installed on the right side wall of the snap-fit ​​member 581, and the lower end of the snap-fit ​​member 581 in the initial position is snapped into the L-shaped groove opened in the vibration frame 364 located on the right side.

[0048] During the actual operation, the dispensing head is in a descending state before being placed inside the cleaning head 55. After the lower end of the dispensing head contacts the sealing cover 562, the two descend synchronously. At this time, the sliding cylinder 561, the sliding plate 566, and the extrusion member 57 descend synchronously. The extrusion member 57 squeezes the guide plate 582 to make the clamping member 581 move to the right so that it is no longer clamped with the L-shaped groove. At this time, the position between the built-in shell 51 and the vibration frame 364 is unlocked.

[0049] Reference Figure 7As shown, when the insertion head 56 is squeezed by the dispensing head and drops to the lowest position (at this time the dispensing head has entered the interior of the cleaning head 55), the alignment head 564 connected to the lower end of the plug-in 563 needs to be positioned with the vibration group 59, and then the two are synchronously lifted and lowered under the vibration movement operation, so as to perform intermittent in-depth high-pressure atomization cleaning on the nozzle of the dispensing head. The present application further improves the structure of the vibration group 59, and its specific structure is as follows: the vibration group 59 includes a vibration block 591, a connecting cavity 592, an entrance port 593, a movable plate 594, a clamping block 595, and a blocking plate 596. The vibration block 591 is slidably arranged in the through groove up and down, an L-shaped connecting cavity 592 is opened in the middle part of the vibration block 591, an entrance port 593 is opened at the upper end of the vibration block 591, and the movable plate 594 is horizontally slidably arranged in the working groove opened on the left side of the vibration block 591 The movable plate 594 is elastically connected to the working groove, a clamping block 595 is installed at the upper end of the movable plate 594, a blocking plate 596 is installed in the middle of the movable plate 594, a docking port is opened in the middle of the blocking plate 596, and the docking port in the initial position and the connecting cavity 592 are staggered, and are in a blocked state at this time; a connecting cavity 501 is opened at the upper end of the built-in shell 51, an alignment port 502 is opened on the left side of the connecting cavity 501, and the alignment port 502 is connected to the connecting cavity 592, and the width of the alignment port 502 is greater than the width of the lower end inlet of the connecting cavity 592. Since the connecting cavity 592 is opened in the middle of the vibration block 591, the vibration block 591 is in a lifting motion during subsequent operations, and the width of the lower end inlet of the connecting cavity 592 is less than the width of the alignment port 502, which can ensure that the connecting cavity 592 in the lifting state is always in a connected state with the alignment port 502.

[0050] In the actual operation process, after the lower end of the dispensing head contacts the sealing cover 562, the two are synchronously lowered, and the sliding cylinder 561 and the plug-in 563 and the alignment head 564 inside it are synchronously lowered until the alignment head 564 is inserted into the entry port 593. At this time, the sliding cylinder 561 continues to keep descending, and the contact block 583 on the right-moving clamping member 581 squeezes the movable plate 594 to move to the right. When the sliding cylinder 561 descends to the lowest position, the clamping block 595 at the upper end of the movable plate 594 is clamped into the alignment head In the card-jointing groove 565 in 564, the position of the plug-in 563 and the vibration block 591 is locked, and the docking port on the blocking plate 596 in the middle of the movable plate 594 is aligned with the connecting cavity 592, which is now in a ventilated state. Subsequently, the intermittently lifted vibration frame 364 drives the contact head 60 to squeeze and lift the vibration block 591, so that the plug-in 563 intermittently penetrates into the interior of the dispensing head nozzle, and the cleaning agent is sprayed out through the high-pressure atomization of the spray hole to clean the inner wall of the nozzle, thereby preventing blockage.

[0051] Reference Figures 1 to 3As shown, the spray assembly 6 includes a baffle 61, which is fixedly mounted on the rear end of the base plate 1. A delivery pump 62 is installed on the side wall of the baffle 61. The outlet position of the delivery pump 62 is connected to the connecting pipe 1 63 and the connecting pipe 2 64 through a three-way valve, respectively. The connecting pipe 1 63 is connected to the connecting chamber 501, and the connecting pipe 2 64 is connected to the connecting chamber.

[0052] In the actual operation process, the delivery pump 62 is connected to an external storage barrel filled with detergent, and the detergent is delivered to the connecting pipe 1 63 and the connecting pipe 2 64 through the delivery pump 62 and delivered to the placement component 4 and the cleaning component 5 respectively, and appropriate high-pressure spraying is performed according to the actual situation. When the dispensing head enters the placement part 42 in the placement component 4, the detergent is sprayed out from the atomization hole (the connecting cavity 592 in the cleaning component 5 is in a blocked state). When the dispensing head enters the cleaning head 55 in the cleaning component 5, the connecting cavity 592 is opened, and the lifting plug-in 563 intermittently penetrates into the inside of the dispensing head nozzle. The detergent is sprayed out through the high-pressure atomization of the spray hole to clean the inner wall of the nozzle. At this time, the connecting cavity connected to the connecting pipe 2 64 is subjected to the elastic squeezing effect of the blocking plate 45 connected to the telescopic rod, so that more detergent is gathered in the connecting pipe 1 63, and then sprayed out from the spray hole at the upper end of the plug-in 563.

[0053] Working principle:

[0054] Step 1: Use ultrasonic cleaning and drying to clean the LED bracket, apply silver glue to the bottom electrode of the LED tube core and expand it, place the expanded tube core on the crystal piercing table, use a crystal piercing pen to install the tube core on the corresponding pad of the bracket and sinter to solidify the silver glue, use aluminum wire or gold wire welding machine to connect the electrode to the LED tube core as the lead for current injection;

[0055] Step 2: The gantry 7 drives the dispensing assembly 8 to move in multiple directions, so that the dispensing head on the dispensing assembly 8 is moved to the placement assembly 4 for sleeve placement, and the cleaning agent is sprayed out from the placement assembly 4 through the spray assembly 6 to temporarily clean the placed dispensing head;

[0056] Step 3: The LED bracket is transported to the positioning component 3 through the conveying component 2, and is clamped and positioned by the positioning component 3. The gantry 7 drives the dispensing component 8 to move again to perform dispensing on the LED bracket, thereby sealing and protecting the LED core and welding wire on the LED bracket;

[0057] Step 4: After the glue dispensing is completed, the gantry 7 drives the glue dispensing component 8 to move to the inside of the cleaning head 55, and the high-frequency vibration of the vibration unit 36 ​​drives the positioning component 3 to vibrate with a high frequency and a small amplitude, so as to vibrate the glue on the LED bracket. At the same time, the cleaning head entering the cleaning head 55, on the one hand, drives the cleaning head 55 to rotate horizontally through the electric turntable 54, and wipes the residual liquid around the head of the glue dispensing head through the wiping block. On the other hand, the lifting plug-in 563 intermittently penetrates into the inside of the glue dispensing head nozzle, and the cleaning agent is sprayed out through the spray hole with high pressure atomization to clean the inner wall of the nozzle;

[0058] Step 5: The positioning component 3 loosens the LED bracket, drives the LED bracket after glue dispensing through the conveying component 2, and transfers it to the oven for curing to complete the packaging.
