Technical Field

[0001] The utility model belongs to the technical field of lamp bead dispensing, and particularly relates to an LED lamp bead dispensing device. Background Technique

[0002] In the processing of LED lamp beads, dispensing can prevent impurities such as moisture and dust in the external environment from entering the interior of the LED lamp beads, protect the lamp beads, enhance the performance of the lamp beads, and extend the service life.

[0003] A Chinese patent with the patent publication number CN217963285U discloses a feeding mechanism of an LED lamp bead dispenser, including a base. An feeding mechanism is installed on the base, and a dispensing mechanism is arranged at the tail end of the base. The feeding mechanism includes a driving motor and a transport plate.

[0004] In the above patent, a pushing member is used to push the mounting plate towards the dispensing mechanism, so that the lamp beads on the mounting plate move to the processing table for dispensing. At this time, the mounting plate leaves the guiding plate, and the position of the mounting plate may shift, making it difficult to automatically correct the position of the lamp strip in the front-back direction, which affects the accuracy of the lamp bead dispensing position. Utility Model Content

[0005] In order to overcome the defects mentioned in the above background technique, the utility model provides an LED lamp bead dispensing device capable of automatically correcting the position of the lamp strip.

[0006] The technical solution is: an LED lamp bead dispensing device, including a workbench. An electric push rod is arranged above the workbench, and a dispenser is installed on the telescopic rod of the electric push rod. An operating platform is connected to the workbench, and two fixing blocks are connected to the top of the operating platform. A first sliding rod is slidably connected to each fixing block. A limiting plate for restricting the position of the lamp strip is connected to one end of the two first sliding rods close to each other. A tension spring is connected between the limiting plate and the adjacent fixing block. An extrusion assembly for moving the limiting plate is arranged on the first sliding rod. Two fixing frames are connected to the workbench, and a mounting column is rotatably connected to the upper end of each fixing frame. One of the mounting columns is driven by a reduction motor, and a winding disc is sleeved on each mounting column.

[0007] Further, a groove is opened on the mounting column, and the winding disc is matched with the mounting column through the groove, so that the winding disc rotates when the mounting column rotates.

[0008] Further, the extrusion assembly includes an inclined plate. An inclined plate is connected to one end of the two first sliding rods away from each other, and two extrusion plates are connected to the lower end of the dispenser.

[0009] Further, both the inclined plate and the extrusion plate are provided with inclined surfaces, and the inclined surfaces of the inclined plate and the extrusion plate are in contact and cooperate with each other.

[0010] Furthermore, it also includes a limiting component for limiting the winding disk, the limiting component includes two sliding rods, two sliding rods are slidably connected to the front side of the mounting column, a return spring is connected between the sliding rods and the mounting column, the ends of the two sliding rods that are close to each other are connected to paddles, and the ends of the two sliding rods that are away from each other are connected to wedge blocks.

[0011] Furthermore, the front sides of the wedge blocks are all provided with inclined surfaces, and the rear sides of the wedge blocks are in contact with the front sides of the winding disks to limit the position of the winding disks.

[0012] Furthermore, it also includes a fan, and the fan is installed at the lower part of the glue dispenser.

[0013] Furthermore, it also includes rollers, and the left and right sides of the top of the operating table are rotatably connected with rollers.

[0014] The beneficial effects of the utility model are as follows: 1. After the glue dispenser dispenses glue to the light strip, the glue dispenser rises, the two limit plates move away from each other, the winding disk reels up the light strip, the glue dispenser descends, the extrusion plate squeezes the inclined plate, so that the two limit plates approach each other and contact the front and rear sides of the light strip respectively, so that the position of the light strip in the front and rear directions can be automatically corrected, making the glue dispensing position more accurate.

[0015] 2. The back side of the wedge block contacts the front side of the winding disk, which can limit the winding disk and prevent it from detaching from the mounting column during rotation, making the winding process of the light strip more stable. By turning the paddle, the back side of the wedge block no longer contacts the front side of the winding disk, and the winding disk can be removed for replacement. BRIEF DESCRIPTION OF THE DRAWINGS

An electric push rod 2 is installed above the workbench 1, and a dispensing device 3 is installed on the telescopic rod of the electric push rod 2. The top of the workbench 1 is connected with an operating table 4. Fixing blocks 5 are symmetrically and fixedly connected to the front and rear of the top of the operating table 4. First sliding rods 6 are slidably connected to the fixing blocks 5. Limiting plates 7 for restricting the position of the lamp strip are fixedly connected to one ends of the two first sliding rods 6 close to each other. Tensile springs are fixedly connected between the limiting plates 7 and the adjacent fixing blocks 5. An extrusion assembly for moving the limiting plate 7 is provided on the first sliding rod 6. Fixing frames 8 are symmetrically and fixedly connected to the left and right of the top of the workbench 1. Mounting columns 9 are rotatably connected to the upper ends of the fixing frames 8. The left mounting column 9 is driven by a reduction motor. Winding discs 10 are sleeved on the mounting columns 9. Grooves are formed in the mounting columns 9, and the winding discs 10 are matched with the mounting columns 9 through the grooves so that the winding discs 10 are driven to rotate when the mounting columns 9 rotate.

[0025] Refer to Figures 2 - 4 , the extrusion assembly includes an inclined plate 71 and a pressing plate 72. Inclined plates 71 are fixedly connected to one ends of the two first sliding rods 6 away from each other. Pressing plates 72 are symmetrically and fixedly connected to the front and rear of the lower end of the dispensing device 3; both the inclined plate 71 and the pressing plate 72 are provided with inclined surfaces, and the inclined surfaces of the inclined plate 71 are in contact and cooperation with the inclined surfaces of the pressing plate 72.

[0026] Refer to Figure 5 and Figure 6 , further including a limiting assembly for limiting the winding disc 10. The limiting assembly includes a second sliding rod 101, a dial 102 and a wedge block 103. Two symmetric second sliding rods 101 are slidably connected to the front sides of the mounting columns 9. A return spring is fixedly connected between the second sliding rods 101 and the mounting columns 9. Dials 102 are fixedly connected to one ends of the two second sliding rods 101 close to each other. Wedge blocks 103 are fixedly connected to one ends of the two second sliding rods 101 away from each other. Inclined surfaces are provided on the front sides of the wedge blocks 103, and the rear sides of the wedge blocks 103 are in contact with the front sides of the winding discs 10, so as to limit the position of the winding discs 10 through the wedge blocks 103.

[0027] Refer toFigure 5 , further including rollers 12, and the left and right sides of the top of the operating table 4 are rotatably connected with rollers 12 respectively.

[0028] Initially, the pressing plate 72 presses the inclined plate 71, the tension spring is in a stretched state, the light belt is wound around the winding disc 10, and the winding mode of the winding disc 10 and the height of the operating table 4 are as Figure 1 shown, so that the light belt fits on the top surface of the operating table 4 and the rollers 12, avoiding the arching of the light belt; first, control the dispenser 3 to apply glue to the light belt. After the glue application at this position is completed, control the electric push rod 2 to drive the dispenser 3 to rise, driving the pressing plate 72 to move upward together. When the pressing plate 72 is separated from the inclined plate 71, the pressing plate 72 no longer presses the inclined plate 71, the tension spring restores, driving the two inclined plates 71 to move away from each other, and at the same time the two limiting plates 7 move away from each other.

[0029] At this time, control the reduction motor to drive the left mounting post 9 to rotate clockwise. The winding disc 10 cooperates with the mounting post 9 through the groove. For specific reference, see Figure 5 and Figure 6 , the left mounting post 9 can drive the left winding disc 10 to rotate clockwise together. The left winding disc 10 winds the light belt, the right winding disc 10 and the right mounting post 9 rotate clockwise, and the right winding disc 10 releases the light belt, so that the next glue application position of the light belt moves to directly below the dispenser 3. At the same time, the rollers 12 can rotate to cooperate with the winding process of the light belt, thereby reducing the wear of the light belt.

[0030] Control the electric push rod 2 to drive the dispenser 3 to descend, driving the pressing plate 72 to descend together. When the pressing plate 72 contacts the inclined plate 71, the pressing plate 72 presses the inclined plate 71 through the inclined surface, causing the two inclined plates 71 to approach each other, driving the first slide bar 6 and the limiting plate 7 to move together, the tension spring stretches, the two limiting plates 7 approach each other and respectively contact the front and rear side surfaces of the light belt, and the two limiting plates 7 can automatically correct the position of the light belt in the front and rear directions, making the glue application position more accurate, and the dispenser 3 can apply glue to the light belt again.

[0031] The rear side of the wedge block 103 contacts the front side of the winding disc 10, which can limit the winding disc 10 and prevent the winding disc 10 from disengaging from the mounting post 9 during the rotation process, making the winding process of the light belt more stable; when the glue application of the entire light belt is completed, manually move the toggle 102 to make the two toggles 102 approach each other, driving the second slide bar 101 and the wedge block 103 to move together. The rear side of the wedge block 103 no longer contacts the front side of the winding disc 10, and then the winding disc 10 can be removed for replacement. Release the toggle 102, and under the action of the return spring, the toggle 102, the second slide bar 101 and the wedge block 103 return to their original positions; then, put the next winding disc 10 on the mounting post 9. The shape of the wedge block 103 is as Figure 6As shown, the winding disc 10 presses against the wedge block 103. After the winding disc 10 is sleeved on the mounting post 9, the wedge block 103 resets under the action of the return spring. The rear side of the wedge block 103 contacts the front side of the winding disc 10, and the winding disc 10 can be limited again.

[0032] Embodiment 2: On the basis of Embodiment 1, referring to Figure 2 and Figure 3 , it further includes a fan 11. The fan 11 is installed on both the left and right sides of the lower end of the dispenser 3; the fan 11 blows air at the dispensing position of the light strip to keep the dispensing position clean and dry, facilitating subsequent dispensing work.
