[0020] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0021] like Figure 1-Figure 3As shown, the present embodiment provides a flexible Mini ejector reversing mechanism for LED packaging, comprising a rotating main seat 1, the lower bottom surface of the rotating main seat 1 is fixedly connected to a rotating base 4, the lower bottom surface of the rotating base 4 is fixedly connected to a bearing fixing seat 14, a U-shaped groove 20 is provided on one side of the rotating base 4, a bearing 16 is rotatably connected to the inner part of the bearing fixing seat 14, an ejector 13 is slidably connected to the inner part of the bearing 16, one end of the ejector 13 passes through the U-shaped groove 20 and the rotating main seat 1 respectively, and the ejector 13 is rotatably connected to the rotating main seat 1, a rotating head 19 is rotatably connected to the inner side of the rotating main seat 1 close to the ejector 13, and one end of the ejector 13 is connected to the rotating main seat 1. The upper surface of the rotating head 19 will remain at the same water surface in the initial state. The rotating head 19 can rotate 360° in all directions and can quickly reverse the direction of the LED material. The lower bottom surface of the rotating head 19 is rotatably connected to the synchronous wheel fixed shaft 17, and the lower bottom surface of the synchronous wheel fixed shaft 17 is fixedly connected to the bearing fixing seat 14. When the LED material moves to the upper surface of the rotating head 19, when it is detected that the direction of the LED material is opposite to the packaging direction, the top rod 13 slides downward inside the bearing 16, so that the LED material is only located on the upper surface of the rotating head 19, and then the LED material is driven to rotate by rotating the rotating head 19, so as to achieve the purpose of adjusting the LED direction.
[0022] Further, such as Figure 1-Figure 3 As shown, the outer wall of the push rod 13 is slidably connected with a compression spring 15, and the two ends of the compression spring 15 are respectively fixedly connected to one side of the bearing fixing seat 14 and one side of the push rod 13. The push rod 13 is easily reset by the compression spring 15, and the elasticity of the compression spring 15 decreases after long-term use. The compression spring 15 can be directly replaced by removing the rotating head 19 and the rotating main seat 1 and taking out the push rod 13. Removing the rotating head 19 and the rotating main seat 1 will not affect the installation accuracy, and there is no need for secondary accuracy adjustment.
[0023] Going further, Figure 1-Figure 3 As shown, a groove 21 is provided on one side of the rotating head 19 and on the side of the rotating head 19 close to the top rod 13. The groove 21 corresponds to the LED material. When the top rod 13 moves downward, the LED material is located inside the groove 21, so that when the rotating head 19 drives the LED material to rotate, the LED material will not shake.
[0024] Among them, Figure 1-Figure 3 As shown, a gasket 2 is fixedly connected between the upper surface of the rotating base 4 and the rotating head 19. The upper surface of the rotating main seat 1 and the panel plane should be kept at the same horizontal plane to prevent material jamming and waste problems during operation. Corresponding adjustments are made by stacking or reducing the gasket 2.
[0025] Further, such as Figure 1-Figure 3As shown, a push rod washer 18 is commonly connected between the rotating head 19 and the synchronous wheel fixed shaft 17. The height of the push rod 13 is adjusted by stacking or reducing the push rod washers 18 so that the plane of the rotating head 19 and the upper end surface of the push rod 13 must be ensured to be on the same horizontal plane.
[0026] Among them, Figure 1-Figure 3 As shown, a belt tensioning plate 5 is fixedly connected to the lower bottom surface of the rotating base 4, and a photoelectric switch bracket 6 is slidably connected to the lower bottom surface of the belt tensioning plate 5. The end of the photoelectric switch bracket 6 close to the top rod 13 is fixedly connected to the photoelectric switch 12. The photoelectric switch 12 is located on the lower bottom surface of the bearing 16 fixed plate, and the photoelectric switch 12 corresponds to one end of the top rod 13. When the top rod 13 slides downward, one end of the top rod 13 will slide into the inside of the photoelectric switch 12, and the photoelectric switch 12 can limit the top rod 13 accordingly. The photoelectric switch 12 is rotated to drive the top rod 13 to rotate, and then the top rod 13 drives the rotating head 19 to rotate.
[0027] Further, such as Figure 1-Figure 3 As shown, an eccentric shaft 3 is provided on the upper surface of the photoelectric switch 12, and the outer wall of the eccentric shaft 3 is in conflict with the upper surface of the photoelectric switch 12. Through the eccentric shaft 3, the photoelectric switch bracket 6 can be moved up and down for fine adjustment, and the limit point of the photoelectric switch 12 is moved to the lower end surface of the top rod 13.
[0028] Among them, Figure 1-Figure 3 As shown, the lower bottom surface of the belt tensioning plate 5 is fixedly connected to a motor mounting plate 9, and the lower bottom surface of the motor mounting plate 9 is fixedly connected to a servo motor 8. The servo motor is used as a drive to ensure the high precision of the commutation angle. The upper surface of the motor mounting plate 9 is rotatably connected to a large synchronous wheel 7, and the output end of the servo motor 8 is connected to the large synchronous wheel 7. The lower end of the photoelectric switch 12 is connected to a small synchronous wheel 11, and the small synchronous wheel 11 and the outer wall of the large synchronous wheel 7 are rotated together and connected to a synchronous belt 10. The large synchronous wheel 7 is driven to rotate by the servo motor 8, and the synchronous belt 10 is driven to rotate by the large synchronous wheel 7. Finally, the small synchronous wheel 11 is driven to rotate under the action of the synchronous belt 10, and the photoelectric switch 12 is rotated synchronously under the drive of the small synchronous wheel 11.
[0029] like Figure 1-Figure 3As shown, the principle of the LED package flexible Mini ejector reversing mechanism provided in this embodiment is as follows: when it is detected that the direction of the LED material is opposite to the packaging direction, the ejector 13 slides inside the bearing 16, so that one end of the bearing 16 slides into the inside of the photoelectric switch 12, and then the large synchronous wheel 7 is driven to rotate by the servo motor 8, and then the synchronous belt 10 is driven to rotate by the large synchronous wheel 7, and finally the small synchronous wheel 11 is driven to rotate under the action of the synchronous belt 10, and the photoelectric switch 12 is synchronously rotated under the drive of the small synchronous wheel 11, so that the photoelectric switch 12 drives the ejector 13 to rotate, and the ejector 13 is used to drive the bearing 16 and the rotating head 19 to rotate, so as to turn the LED material.
[0030] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
[0031] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
