Description

Technical Field

[0001] This utility model relates to the field of LED packaging technology, specifically to an automatic positioning mechanism for an LED packaging dispensing machine. Background Technology

[0002] The function of packaging is to provide sufficient protection for the chip, preventing it from failing due to long-term exposure to air or mechanical damage, thereby improving the chip's stability. For LED packaging, good heat dissipation is also necessary. Good packaging allows LEDs to have better luminous efficiency and a better heat dissipation environment, thus extending the LED's lifespan. Packaging is a key step in the manufacturing of white LEDs: the light-emitting mechanism of semiconductor materials determines that a single LED chip cannot emit continuous white light. Therefore, the process must mix two or more complementary colors of light to form white light. Currently, there are three main methods to achieve white LEDs: blue LED + YAG yellow phosphor, RGB tri-color LED, and ultraviolet LED + multi-color phosphor. The realization of white LEDs all depends on the packaging stage. Good process precision control, as well as good materials and equipment, are the guarantee of consistency in white LED devices. LED dispensing machines are specialized equipment used to dispense adhesives onto LED products. With the continuous maturation of dispensing machine technology, the products that can be applied are constantly increasing, mainly including multiple production fields such as the electronic lighting industry, the machinery and hardware industry, and the automotive manufacturing industry.

[0003] Therefore, Chinese Patent Publication No. CN 217595024 U discloses a positioning mechanism for an LED encapsulation dispensing machine, including a chassis shell, an LED workpiece platform on top of the chassis shell, a slot for the LED workpiece platform on the chassis shell, a motor on one side of the chassis shell, a lead screw at one end of the motor's output shaft, a connecting bracket below the LED workpiece platform, a connecting block below the connecting bracket for the lead screw to pass through, and a slide rail below the connecting block. This utility model provides a positioning mechanism specifically for LED encapsulation adhesive dispensing, which can be directly controlled by a computer without close operator intervention. The dispensing pen can move up, down, left, and right, and the LED workpiece platform can move back and forth.

[0004] However, the positioning mechanism of the LED packaging dispensing machine can only dispense adhesive on one side of the LED product. In actual dispensing, some LED products need to be dispensed on the side edges, which leads to a defect in the use of the device. Utility Model Content

[0023] Please see Figure 1-4This utility model provides a technical solution: an automatic positioning mechanism for an LED packaging dispensing machine, including a base 1, a mounting frame 2 fixedly connected to the top of the base 1, a lead screw 11 rotatably connected to the top of the mounting frame 2, limit blocks 12 symmetrically slidably connected to both ends of the mounting frame 2, a movable frame 9 fixedly connected to one end of the limit block 12, the movable frame 9 moving along with the limit block 12, two sets of movable frames 9 are provided, the two sets of movable frames 9 are respectively threaded to both ends of the lead screw 11, the lead screw 11 rotating along with the movable frames 9 at both ends, grooves 16 are provided at the four corners of the top of the mounting frame 2, connecting posts 18 are detachably connected inside the grooves 16, one end of the connecting post 18 is fixedly connected to an LED working platform 7, the connecting post 18 rotating along with one end of the LED working platform 7. The tilt angle of the LED work platform 7 is adjusted. An incomplete gear 8 is fixedly connected to the end of the connecting column 18 away from the moving plate 17. The rotation of the incomplete gear 8 causes the connecting column 18 to rotate. The top two ends of the mounting frame 2 are symmetrically slidably connected to the moving plate 17. The two ends of the moving plate 17 are symmetrically fixedly connected to the rack 10. The movement of the moving plate 17 causes the rack 10 to move. One side of the rack 10 is meshed with the incomplete gear 8. The movement of the rack 10 causes the incomplete gear 8 to rotate. A support frame 3 is fixedly connected to one side of the top of the mounting frame 2. A mounting plate 4 is slidably connected to one side of the mounting frame 2. There are two sets of mounting plates 4. A glue pen 5 is installed between the two sets of mounting plates 4. The movement of the mounting plate 4 causes the glue pen 5 to move, so as to better move the glue pen 5 to the appropriate position.

[0024] Furthermore, one side of the mounting bracket 2 is symmetrically provided with a sliding groove 13 that penetrates its surface. A connecting plate 15 is slidably connected inside the sliding groove 13, and the connecting plate 15 moves inside the sliding groove 13.

[0025] Furthermore, the top of the connecting plate 15 is fixedly connected to the movable plate 17, and the moving plate 15 moves the movable plate 17 along with it.

[0026] Furthermore, a second electric telescopic rod 14 is symmetrically fixedly connected to the bottom of the mounting frame 2. The output end of the second electric telescopic rod 14 is fixedly connected to the connecting plate 15. After the second electric telescopic rod 14 is opened, it moves with the connecting plate 15.

[0027] Furthermore, a fixing plate 19 is symmetrically fixedly connected to the top of the base 1, and both ends of the lead screw 11 are rotatably connected to the fixing plate 19. A motor 20 is fixedly connected to one side of the fixing plate 19, and one end of the lead screw 11 passes through one side of the fixing plate 19 and is fixedly connected to the output end of the motor 20. When the motor 20 is turned on, it rotates the lead screw 11.

[0028] Furthermore, a first electric telescopic rod 6 is fixedly connected to the top of the support frame 3. The output end of the first electric telescopic rod 6 passes through the top of the support frame 3 and is fixedly connected to the mounting plate 4. When the first electric telescopic rod 6 is opened, the first electric telescopic rod 6 moves the mounting plate 4.

[0029] In use, the LED product to be processed is fixed on the surface of the LED work platform 7 using a clamp. The motor 20 is turned on, causing the lead screw 11 to rotate. The rotation of the lead screw 11 moves the two movable frames 9 at both ends, which in turn move the limiting blocks 12. One set of movable frames 9, with the limiting blocks 12, moves above the groove 16, restricting the connecting post 18 at one end of the LED work platform 7. The other set of movable frames 9, with the limiting blocks 12, moves away from above the groove 16, allowing the other end of the LED work platform 7 to leave the groove 16. Then, the second electric telescopic rod 14 is activated, and the second electric telescopic rod 14... The connecting plate 15 moves within the slide groove 13, and the moving plate 17 moves along with the moving plate 17. The moving plate 17 moves along with the racks 10 at both ends. When the moving plate 17 moves in one direction, the rack 10 at one end rotates along with a set of incomplete gears 8, causing one end of the LED working platform 7 to tilt up. This adjusts the tilt angle of the LED working platform 7, making it easier to apply adhesive to the side of the LED product on the surface of the LED working platform 7. The first electric telescopic rod 6 is activated, and the first electric telescopic rod 6 moves along with the dispensing pen 5 via the mounting plate 4, moving the dispensing pen 5 to the appropriate position for dispensing.
