Description

Technical Field

[0001] The present invention relates to the technical field of LED lamp beads, and more particularly to an automatic encapsulation device for LED lamp beads. Background Art

[0002] During the encapsulation process of lamp beads, filling the bottom glue is an important process. Its main function is to protect the LED die and bonding wires, and at the same time improve the light extraction efficiency. The specific method is as follows: By means of dispensing, epoxy resin or other types of glue are dispensed between adjacent lamp bead tapes on the substrate, and then cured. Since there are various models of LED lamp boards processed on the line, and the number of lamp beads set on the substrate is also different, the gap position and gap size between adjacent lamp bead tapes will change. Therefore, it is necessary to frequently change the model and replace the new dispensing head module to adapt to the new processing model. However, the existing dispensing equipment requires skilled workers to disassemble and debug during model change, and the debugging time is relatively long, delaying the production progress.

[0003] In view of the above problems, a dispensing device that can quickly adapt to the change of lamp bead spacing during model change is needed. Therefore, we made improvements and proposed an automatic encapsulation device for LED lamp beads. Summary of the Invention

[0041] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] As described in the background art, the existing glue dispensing equipment requires skilled workers to disassemble and debug when changing models, the debugging time is relatively long, and the production progress is delayed.

[0043] To solve this technical problem, the present invention provides an automatic encapsulation device for LED lamp beads, which is applied to the process of filling the bottom glue of LED lamp beads for encapsulation.

[0044] Specifically, please refer to Figures 1 - 3 , the automatic encapsulation device for LED lamp beads specifically includes:

[0045] An installation component 100, including a processing table 101, on the top of the processing table 101 is provided a conveyor belt 102, as Figure 1 shown, the processing table 101 bears the entire device, and the conveyor belt 102 is responsible for the transfer during the processing of the LED lamp board; and,

[0046] A dispensing component 200, including a first support table 201 arranged on the top of the processing table 101, a moving beam frame 203 arranged on the side of the first support table 201, a glue delivery structure 204 arranged on the side of the moving beam frame 203, a dispensing structure 205 arranged at the bottom of the glue delivery structure 204, and a second support table 202 arranged on the side of the glue delivery structure 204, as Figure 2 shown, the first support table 201 straddles above the conveyor belt 102. During the processing, the moving direction of the conveyor belt 102 is from the dispensing component 200 towards the curing component 300. One end of the conveyor belt 102 close to the dispensing component 200 is the loading end. The lamp board is transported by the conveyor belt 102 to below the moving beam frame 203, and the moving beam frame 203 drives the glue delivery structure 204 and the dispensing structure 205 to reciprocate in the direction perpendicular to the moving direction of the conveyor belt 102. The glue in the glue delivery structure 204 fills the bottom glue of the parts on the lamp board surface that need to be filled through the dispensing structure 205; and,

[0047] A curing component 300, as Figure 1 shown, when the glue filling is completed, the conveyor belt 102 continues to drive the lamp board to move into the curing component 300 for curing treatment; and,

[0048] A debugging component 400, as Figure 1 shown, when a model change is required, the debugging component 400 can be used to simulate the lamp board to be changed. By moving the moving beam frame 203 once in its working direction, the overall shape and position arrangement of the dispensing structure 205 can be adjusted to meet the lamp board to be processed subsequently, making the model change simple and convenient and improving the work efficiency.

[0049] The automatic encapsulation device for LED lamp beads provided by the present invention can achieve the effect of automatically filling and curing the bottom glue between the lamp beads on the substrate. At the same time, when changing the model, the distance between the dispensing tubes can be automatically adjusted according to the changing distance between the lamp bead tapes. The moving beam frame 203 will drive the glue conveying structure 204 and the dispensing structure 205 to reciprocate in a direction perpendicular to the movement direction of the conveyor belt 102 to fill the glue. After the glue filling is completed, the conveyor belt 102 will continue to drive the lamp board to move into the curing member 300 for curing treatment. When it is necessary to change the model, the debugging member 400 can be used to simulate the lamp board to be changed, and the overall shape and position arrangement of the dispensing structure 205 can be adjusted by moving the moving beam frame 203 once in its working direction.

[0050] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0051] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0052] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0053] Example 1, please refer to Figures 1 - 4 , an automatic encapsulation device for LED lamp beads, the first support platform 201 thereof includes an arched platform body 201a arranged on the top of the processing platform 101. A translation slideway 201b is arranged on the side surface of the arched platform body 201a, a rack 201c is arranged on the side surface of the translation slideway 201b, the moving beam frame 203 includes a beam body 203a, the beam body 203a can slide on the translation slideway 201b, a motor 203b is arranged on the side surface of the beam body 203a, a gear 203c is arranged on the output shaft of the motor 203b, the gear 203c meshes with the rack 201c, a vertical chute 203d is opened on the bottom side surface of the beam body 203a, the motor 203b drives the gear 203c to rotate, and the gear 203c will drive the entire beam body 203a to slide on the arched platform body 201a under the action of the rack 201c, so as to drive the glue conveying structure 204 and the dispensing structure 205 to reciprocate in a direction perpendicular to the movement direction of the conveyor belt 102 on the lamp board to be dispensed.

[0054] By driving the gear 203c to rotate through the motor 203b, the gear 203c will drive the entire beam body 203a to slide on the arched platform body 201a under the action of the rack 201c, and the glue conveying structure 204 reciprocates to automatically fill the glue in the area to be filled on the lamp board, with stable movement and uniform dispensing.

[0055] Please refer to Figures 1 - 5, An automatic encapsulation device for LED lamp beads. The glue dispensing structure 204 includes a connecting frame 204a arranged on the side of the beam body 203a. The side of the connecting frame 204a is fixedly connected to the beam body 203a. A glue bucket 204b is arranged on the top of the connecting frame 204a. The glue bucket 204b contains the glue to be used. A glue dispensing pump 204d is arranged at the bottom of the glue bucket 204b. The glue dispensing pump 204d is communicated with the glue bucket 204b. A glue distribution box 204c is arranged on the inner wall of the connecting frame 204a. The glue distribution box 204c is communicated with the glue dispensing pump 204d. During the glue dispensing operation, when glue is needed, the glue dispensing pump 204d will work to transport the glue in the glue bucket 204b to the glue distribution box 204c. The glue dispensing structure 205 includes flexible glue dispensing tubes 205a arranged at the bottom of the glue distribution box 204c. The number of the flexible glue dispensing tubes 205a is multiple, and the flexible glue dispensing tubes 205a can be removed or added when setting up the equipment or changing the model, and can be changed according to the required quantity, so that the equipment can adapt to more models of lamp boards to be encapsulated. The glue outlet of each flexible glue dispensing tube 205a is located in the middle of the spacing between adjacent LED lamp bead belts on the lamp board to ensure accurate glue filling position and flat shape when the glue is finally cured. During operation, the glue is distributed from the glue distribution box 204c to each flexible glue dispensing tube 205a and added to the lamp board from the flexible glue dispensing tubes 205a. A retaining frame 205c is arranged on the side of the flexible glue dispensing tube 205a. A C-shaped mounting plate 205b is arranged at the bottom of the retaining frame 205c. A motion mechanism 205d is arranged inside the C-shaped mounting plate 205b. The number of the motion mechanisms 205d is the same as that of the flexible glue dispensing tubes 205a, and the motion mechanism 205d is connected to the flexible glue dispensing tube 205a. During normal operation, the motion mechanism 205d will be locked. When changing the model, under the action of the debugging component 400, the movement of the glue dispensing component 200 will cause the motion mechanism 205d to slide in the C-shaped mounting plate 205b, and the motion mechanism 205d will drive the flexible glue dispensing tube 205a to move. An unlocking mechanism 205e is arranged on the side of the C-shaped mounting plate 205b away from the flexible glue dispensing tube 205a.

[0056] During the glue dispensing operation, when glue is needed, the glue dispensing pump 204d will work to transport the glue in the glue bucket 204b to the glue distribution box 204c, and then the glue is distributed from the glue distribution box 204c to each flexible glue dispensing tube 205a and added to the lamp board from the flexible glue dispensing tubes 205a. Each glue dispensing tube accurately dispenses glue on each lamp belt spacing. At the same time, the flexible glue dispensing tubes 205a can be removed or added when setting up the equipment or changing the model, and can be changed according to the required quantity, enabling the equipment to adapt to more models of lamp boards to be encapsulated.

[0057] Embodiment 2 further optimizes the automatic encapsulation device for LED lamp beads provided in Embodiment 1. Specifically, as Figure 6As shown, the flexible dispensing tube 205a includes a telescopic tube 205a-1 which can be bent and telescoped. The top of the telescopic tube 205a-1 is connected to the dispensing box 204c. At the bottom of the telescopic tube 205a-1, there is an inner dispensing tube 205a-2, and an outer dispensing tube 205a-3 is sleeved on the outer wall of the inner dispensing tube 205a-2. The inner dispensing tube 205a-2 is connected to the telescopic tube 205a-1. The outer dispensing tube 205a-3 can rotate on the outer wall of the inner dispensing tube 205a-2. At the bottom of the outer dispensing tube 205a-3, there is a long and narrow dispensing port 205a-4. On the outer wall of the outer dispensing tube 205a-3, there is a flat through groove 205a-5, and an inclined groove 205a-6 is arranged above the flat through groove 205a-5. The bottom dispensing port of the outer dispensing tube 205a-3 is long and narrow. When filling the lamp board with glue, observing the outer dispensing tube 205a-3 from the vertical direction of the movement direction of the conveyor belt 102, the projected width of the dispensing port at the bottom of the outer dispensing tube 205a-3 in this direction has a greater impact on the final filling width of the dispensed glue. By changing this projected width and simultaneously changing the conveying power of the glue delivery pump 204d, the filling width can be adjusted. Due to the requirements of product changeover, the positions of adjacent light belts on the lamp board will change, so the center line of the distance between the light belts will change, and the size of the distance itself will also change. During product changeover, it is not only required that the dispensing port of the flexible dispensing tube is located on the center line of the distance, but also it is best that the dispensing port of the dispensing tube can be adjusted according to the size of the distance. The movement mechanism 205d drives the flexible dispensing tube to move, which can adjust the position of the dispensing port of the dispensing tube. At the same time, the movement mechanism 205d can also drive the outer dispensing tube 205a-3 to rotate on the inner dispensing tube 205a-2 to change the included angle between the connection line between the farthest points of the long and narrow dispensing port 205a-4 and the distance between the light belts, so as to change the projected width of the dispensing port in the vertical direction of the distance, and then adjust the dispensing width. Moreover, the device can increase this projected width according to the increase of the distance and relatively decrease it according to the decrease of the distance.

[0058] The telescopic tube 205a, which is connected to the dispensing box 204c, of the flexible dispensing tube 205a can be bent and telescoped, and can quickly adapt to the new position when it is necessary to move the flexible dispensing tube 205a to change the position of the dispensing port during product changeover, without having to disassemble the dispensing equipment, which can save time. The dispensing port of the flexible dispensing tube 205a is determined by the outer dispensing tube 205a-3 sleeved on the outer wall of the inner dispensing tube 205a-2, and the outer dispensing tube 205a-3 can rotate outside the inner dispensing tube 205a-2, so as to change the projected width of the dispensing port in the vertical direction of the distance, and then adjust the dispensing width, enabling the dispensing width of the device to be quickly adjusted adaptively according to the size of the distance during product changeover, without having to replace the dispensing equipment, saving time.

[0059] Furthermore, as Figures 7 - 10As shown, the C-shaped multiplying plate 205b includes a C-shaped plate body 205b-1. The side surface of the C-shaped plate body 205b-1 is connected to the first support platform 201. A window groove 205b-2 is formed on the side surface of the C-shaped plate body 205b-1. The cage 205c includes a cross bar 205c-1. One end of the cross bar 205c-1 is arranged in the vertical sliding groove 203d. The cross bar 205c-1 can slide up and down in the vertical sliding groove 203d. A horizontal sliding groove 205c-2 is formed on the side surface of the cross bar 205c-1.

[0060] Furthermore, the motion mechanism 205d includes a chassis 205d-1 arranged inside the C-shaped plate body 205b-1. Roller wheels 205d-2 are arranged on both sides of the bottom of the chassis 205d-1. A pressing plate 205d-3 is arranged on the top of the chassis 205d-1. The top of the pressing plate 205d-3 abuts against the top of the inner wall inside the C-shaped plate body 205b-1. An elastic member 205d-4 is arranged at the bottom of the pressing plate 205d-3. The elastic member 205d-4 is in a compressed state. A locking plate 205d-5 is arranged at the bottom of the elastic member 205d-4. A connecting rod 205d-6 is arranged on one side of the chassis 205d-1 close to the flexible dispensing tube 205a. A limiting block 205d-7 is arranged at the top of the connecting rod 205d-6. A connecting frame 205d-8 is sleeved on the outer wall of the limiting block 205d-7. The connecting frame 205d-8 can slide up and down on the outer wall of the limiting block 205d-7. However, the limiting block 205d-7 limits the possibility of the connecting frame 205d-8 moving horizontally or rotating. It can only slide up and down. A middle rod 205d-9 is arranged at the top of the connecting frame 205d-8. A slider 205d-10 is arranged on one side of the top of the middle rod 205d-9 close to the cross bar 205c-1. The slider 205d-10 is arranged inside the horizontal sliding groove 205c-2. The slider 205d-10 can slide inside the horizontal sliding groove 205c-2. A first inclined plate 205d-11 is sleeved on the outer wall of the connecting rod 205d-6. A second inclined plate 205d-12 is arranged on the side surface of the first inclined plate 205d-11. Both the first inclined plate 205d-11 and the second inclined plate 205d-12 are sleeved on the outer wall of the connecting rod 205d-6 and can rotate relative to the connecting rod 205d-6. Sliders 205d-10 are arranged on the side surfaces of both the first inclined plate 205d-11 and the second inclined plate 205d-12. As mentioned before, the number of the motion mechanisms 205d is set to be the same as that of the flexible dispensing tubes 205a. Each motion mechanism 205d is connected to its corresponding flexible dispensing tube 205a. The adjacent first inclined plate 205d-11 and second inclined plate 205d-12 are rotationally connected at their tops and connected to the same slider 205d-10. Relative rotation can occur between the first inclined plate 205d-11 and the second inclined plate 205d-12 with respect to the slider 205d-10.

[0061] During tool change, the motion mechanism 205d will be unlocked, causing it to move and drive the flexible dispensing tube 205a to move through the connecting rod 205d-6 to adjust its position, so that the specific dispensing position of the device changes to adapt to the new spacing of the newly replaced model to be filled with glue.

[0062] Embodiment 3 further optimizes the automatic encapsulation device for LED lamp beads provided in Embodiment 1 or 2. Specifically, as Figure 7 shown, the first flexible dispensing tube 205a closest to the first support table 201 (hereinafter referred to as the first dispensing tube), the top of the first inclined plate 205d-11 in the motion mechanism 205d connected thereto is rotatably connected to the cross bar 205c-1, and it will not slide in the horizontal chute 205c-2, but only rotate relative to the cross bar 205c-1. A flexible dispensing tube 205a adjacent to the first dispensing tube (hereinafter referred to as the second dispensing tube). When tool change is required, the lock block of the motion mechanism 205d will be lifted, and the roller 205d-2 will be unlocked and can rotate. The motion mechanism 205d can move within the C-shaped plate body 205b-1. At the same time, due to the connection between adjacent motion mechanisms 205d through the top of the first inclined plate 205d-11 and the second inclined plate 205d-12, as long as the motion mechanism 205d connected to the second dispensing tube slides within the C-shaped plate body 205b-1, all the motion mechanisms 205d can be driven to slide, thereby driving all the dispensing tubes to move. Preferably, the bottom of the lock plate 205d-5 in the motion mechanism 205d connected to the second dispensing tube is processed into a plane with relatively large friction. The bottom of the lock plate 205d-5 is in contact with the roller 205d-2. In the normal dispensing state, this lock plate 205d-5 is pressed by the elastic member 205d-4 to apply pressure to the roller 205d-2, and the rotation of the roller 205d-2 is prevented under the action of friction, thereby locking the motion mechanism 205d, so that all the motion mechanisms 205d are locked, and the bottoms of the other lock plates 205d-5 are processed into smooth planes with relatively small friction.

[0063] During normal filling operation in the processing state, the lock plate 205d-5 makes the motion mechanism 205d unable to move by using the friction force applied to the roller 205d-2. Thus, the position of the flexible dispensing tube 205a is also locked. When tool change is required, as long as the motion mechanism 205d connected to the second dispensing tube slides within the C-shaped plate body 205b-1, all the motion mechanisms 205d can be driven to slide, thereby driving all the dispensing tubes to move, reducing the number of unlocking parts that need to be processed and lowering the usage cost.

[0064] Furthermore, as Figures 8 - 9As shown, one end of the connecting rod 205d-6 away from the chassis 205d-1 passes through the flat through groove 205a-5 and is connected to the glue outlet inner tube 205a-2. The glue outlet inner tube 205a-2 is fixedly connected to the connecting rod 205d-6. When the roller 205d-2 rolls, the chassis 205d-1 and the connecting rod 205d-6 move accordingly. The connecting rod 205d-6 will drive the glue outlet inner tube 205a-2 to move. The glue outlet inner tube 205a-2 always moves together with the chassis 205d-1. That is, the center of the glue outlet of the dispensing tube is always on the same straight line as the center of the connecting rod 205d-6. One end of the middle rod 205d-9 away from the cross bar 205c-1 passes through the inclined groove 205a-6 and is connected to the glue outlet inner tube 205a-2. The groove width of the inclined groove 205a-6 is the same as the outer diameter of the middle rod 205d-9. The middle rod 205d-9 can only slide up and down along the outer wall of the limit block 205d-7 with the connecting frame 205d-8. The middle rod 205d-9 is always on the same straight line as the connecting rod 205d-6. During the sliding of the moving mechanism 205d, the distance between adjacent moving mechanisms 205d will change. Thus, the first inclined plate 205d-11 and the second inclined plate 205d-12 connecting the moving mechanisms 205d will rotate. The cross bar 205c-1 at the top of the inclined plate will slide up and down accordingly. The middle rod 205d-9 on the side of the cross bar 205c-1 will slide up and down. The middle rod 205d-9 is in the inclined groove 205a-6. The sliding of the middle rod 205d-9 will apply torque to the glue outlet outer tube 205a-3 through the inclined groove 205a-6, thereby driving the glue outlet outer tube 205a-3 to rotate, so as to adjust the width of the final glue output and adapt to the new distance.

[0065] When adjusting the position of the flexible dispensing tube 205a, the cross bar 205c-1 will slide up and down with the rotation of the first inclined plate 205d-11 and the second inclined plate 205d-12. Thus, it drives the middle rod 205d-9 to slide and applies torque to the glue outlet outer tube 205a-3 through the inclined groove 205a-6, driving the glue outlet outer tube 205a-3 to rotate, so as to adjust the width of the final glue output. While adjusting the glue output position of the flexible dispensing tube 205a, the width of the glue output is adjusted, which can save the changeover time and improve work efficiency.

[0066] Furthermore, as Figure 10As shown in the figure, the unlocking mechanism 205e includes a bending connecting rod 205e-1 arranged on the side surface of the C-shaped plate body 205b-1. The top of the bending connecting rod 205e-1 penetrates through the window slot 205b-2 and is connected to the lock plate 205d-5. Preferably, since only the movement of the movement mechanism 205d connected to the second glue outlet tube is required to drive the movement of all the movement mechanisms 205d, only one unlocking mechanism 205e needs to be provided and connected to the lock plate 205d-5 in the movement mechanism 205d corresponding to the second glue outlet tube. The bottom sides of the bending connecting rod 205e-1 are both provided with abutting pins 205e-2. The bottom of the abutting pin 205e-2 is processed into a hemispherical shape. The vertical symmetry axis between the two abutting pins 205e-2 and the center line of the middle rod 205d-9 are arranged in the same vertical plane.

[0067] During the processing and glue filling process, the abutting pin 205e-2 will not contact any tooling or products to be processed. During the change of models, the debugging component 400 is used to contact the abutting pin 205e-2 to lift the abutting pin 205e-2 and make the lock plate 205d-5 leave the roller. Thus, the movement mechanism 205d is unlocked, and the position of the flexible dispensing tube 205a can be adjusted. The structural principle is simple and the processing is convenient.

[0068] Example 4 further optimizes the LED lamp bead automatic encapsulation equipment provided in the above embodiments, such as Figure 11As shown, the debugging component 400 includes a bottom plate 401. A simulated light bar 402 is arranged on the top of the bottom plate 401. A resisting slideway 403 is arranged on the top of the simulated light bar 402. A V-shaped slideway 404 is arranged on the side of the resisting slideway 403. Preferably, to explain the entire debugging process, assume that the light strips on the same LED lamp board substrate are reduced, so the spacing between adjacent light strips increases, and the distance between the centers of adjacent spacings increases. Then, the spacing between the glue outlet ports of adjacent glue dispensing tubes needs to be enlarged and adjusted. At this time, we place the debugging component 400 on the glue dispensing station to be processed. The simulated light bar 402 is arranged on the bottom plate 401. Preferably, a debugging slideway is arranged on the second simulated light bar 402. As shown in Figure 3, the beam body 203a moves from the front direction shown in the figure to the rear. At the beginning of the movement, since the position between the simulated light bar 402 and the light bar of the lamp board processed last time has changed, at this time, the center line of the light bar and the vertical symmetry axis of the two abutting needles 205e-2 are not in the same vertical plane. So at this time, the glue outlet of the glue dispensing tube is not at the center of the spacing between adjacent light strips. The beam body 203a continues to move. The resisting slideway 403 will apply an upward force to the abutting needle 205e-2, and the abutting needle 205e-2 is lifted. The bending connecting rod 205e-1 will drive the locking plate 205d-5 to move upward, and the elastic member 205d-4 is compressed. At this time, the moving member connected to the second glue dispensing tube is unlocked. The beam body 203a continues to move. The abutting needle 205e-2 will move between the V-shaped slideways 404. Since there is an offset between the center line of the light bar and the vertical symmetry axis of the two abutting needles 205e-2, the side slideway of the V-shaped slideway 404 close to the first support platform 201 will contact the abutting needle 205e-2 first. At this time, the abutting needle 205e-2 will apply a pressure to this side slideway, and this side slideway will apply a reverse thrust to the abutting needle 205e-2. During the movement, this side slideway will slide the abutting needle 205e-2 in the direction away from the first support platform 201. So the abutting needle 205e-2 drives the moving member to slide in the direction away from the first support platform 201. Then all the moving members will drive all the glue dispensing tubes to move in the direction away from the first support platform 201 until the side slideways on both sides of the V-shaped slideway 404 are in contact with the abutting needle 205e-2. At this time, the center line of the light bar and the vertical symmetry axis of the two abutting needles 205e-2 are in the same vertical plane. Then the glue outlet of the second glue dispensing tube and the glue outlet of the glue dispensing tubes behind it are both at the center of the spacing between adjacent light strips. Then the position of the glue dispensing tube is successfully debugged. And when the moving mechanism 205d moves in the direction away from the first support platform 201, the spacing between adjacent glue dispensing tubes becomes larger. Then the first inclined plate 205d-11 and the second inclined plate 205d-12 will drive the cross bar 205c-1 to slide downward. At this time, the middle rod 205d-9 will slide downward on the side of the outer glue dispensing tube 205a-3, driving the outer glue dispensing tube 205a-3 to rotate. Then the projected width of the glue outlet in the vertical direction of the spacing will increase, and the glue outlet width can be made larger to adapt to a larger light bar spacing. The beam body 203a continues to move.The plunger 205e-2 will disengage from the V-shaped slideway 404 and come into contact with the descending abutment slideway 403. Then, the plunger 205e-2 gradually descends until the locking plate 205d-5 contacts the roller 205d-2, re-locking the moving mechanism 205d. When the distance between adjacent light belts decreases, the above operation process remains the same, but the moving direction of the moving mechanism 205d will be reversed.

[0069] When debugging the position and dispensing width of the dispensing tube during model change, just place the debugging component 400 at the dispensing station to be filled. The beam plate drives the dispensing structure 205 to move once on the debugging component 400. Then, under the cooperation of the plunger 205e-2 and the V-shaped slideway 404, the movement of the moving component can be used to change the position of the dispensing tube and the angle of the dispensing outer tube 205a-3, adapting to the new light belt spacing size and spacing position. This debugging method is simple and easy to operate, without the need for skilled workers to disassemble and debug, saving time and labor costs.

[0070] The usage process of the LED lamp bead automatic encapsulation equipment provided by the present invention is as follows:

[0071] When filling the LED lamp board with glue, place the lamp board to be dispensed at the feeding end of the conveyor belt 102. The lamp board is transported by the conveyor belt 102 to the lower part of the moving beam frame 203. The moving beam frame 203 drives the glue conveying structure 204 and the dispensing structure 205 to reciprocate in a direction perpendicular to the movement direction of the conveyor belt 102 to fill the glue. When a model change is required, just place the debugging component 400 at the dispensing station to be filled. The beam plate drives the dispensing structure 205 to move once on the debugging component 400. Then, under the cooperation of the plunger 205e-2 and the V-shaped slideway 404, the movement of the moving component can be used to change the position of the dispensing tube and the angle of the dispensing outer tube 205a-3, adapting to the new light belt spacing size and spacing position.
