[0002] With the rapid development of semiconductor lighting technology, semiconductor lighting devices such as LEDs have been widely used in various fields. However, in the packaging process of semiconductor lighting devices, the glue coating process is one of the key steps and has an important impact on the performance and reliability of the device. Effective packaging cannot be achieved at the joint between the bottom shell and the lens of the luminaire. During subsequent use, the internal chip of the lighting device is easily affected by physical damage, moisture, chemicals and mechanical stress, which will directly affect the service life of the device. Therefore, the luminaire needs to be glued and packaged.

[0003] Most of the existing luminaire packaging is done manually, and glue is continuously applied to the joint between the luminaire bottom shell and the lens through a glue coating tube. However, the amount of glue cannot be controlled during the manual operation, and the glue coating process is to continuously inject glue into the joint, and then use other tools to scrape it flat to complete the gluing. During the process, not only is the glue coating uneven, but glue overflow is also likely to occur during continuous glue injection, which affects the lighting effect of the luminaire and causes waste of packaging colloid.

[0004] In view of this, an electronic packaging structure for a semiconductor lighting device is provided to overcome the above-mentioned defects. Utility Model Content

[0025] Furthermore, the second motor 17 is connected to the placement plate 5, and a glue storage box 9 is fixedly installed on the top surface of the base frame 1. A glue delivery pump is installed on the outer wall of the glue storage box 9. A glue delivery pipe 10 is fixedly connected between the glue delivery pump and the glue dispensing barrel 16. By setting the glue storage box 9, the glue delivery pipe 10 and the glue delivery pump, the glue in the glue storage box 9 can be transferred to the glue dispensing barrel 16 through the glue delivery pipe 10.

[0026] Furthermore, a square groove is provided inside the glue dispensing barrel 16, and the shape of the moving block 19 is also square. By setting the square groove and setting the shape of the moving block 19 to be also square, the moving block 19 cannot rotate with the reciprocating screw 18 after it rotates, and can only move up and down. A connecting plate 20 is fixedly connected to the bottom surface of the moving block 19, and the other end of the connecting plate 20 is fixedly connected to the glue pushing block 21. By setting the connecting plate 20 and the glue pushing block 21, and setting the upper and lower ends of the connecting plate 20 to be fixedly connected to the moving block 19 and the glue pushing block 21 respectively, the moving block 19 can drive the glue pushing block 21 to move during the up and down movement. A glue outlet is provided at the bottom of the glue dispensing barrel 16, and the glue pushing block 21 is adapted to the glue outlet. By setting the glue pushing block 21, and setting the glue pushing block 21 to be adapted to the glue outlet, the glue pushing block 21 of the device can push glue to drip from the glue outlet during the up and down movement.

[0027] In specific implementation, the user can place the circular lighting fixture in the placement plate 5, and then start the second motor 17 to drive the placement plate 5 to rotate, so that the circular lighting fixture starts to rotate, and at the same time start the glue pump and the first motor 12. After the glue pump is started, the glue is transferred to the glue dispensing barrel 16 through the glue pipe 10. After the first motor 12 is started, the first transmission plate 13 is driven to rotate, and the outer walls of the first transmission plate 13 and the second transmission plate 15 are simultaneously sleeved with a transmission belt 14, so the second transmission plate 15 will also rotate synchronously, and the second transmission plate 15 is fixedly connected to the reciprocating screw 18, so When the second transmission plate 15 rotates, the reciprocating screw 18 will also rotate, and the rotation of the reciprocating screw 18 will drive the moving block 19 to move up and down within the range of the reciprocating screw 18. In the process of the moving block 19 moving up and down, the glue pushing block 21 will repeatedly squeeze the glue in the glue dispensing barrel 16 out of the glue dispensing barrel 16, thereby realizing the glue dispensing work for the lighting fixture. Unlike manual application, the glue squeezed out by the glue dispensing barrel 16 is in the shape of drops and will be applied to the lighting fixture at a uniform speed. In conjunction with the scraper 8 set above the base frame 1, the drop-shaped glue can be scraped flat, thereby realizing uniform glue coating and packaging work.

[0028] By setting a glue dispensing barrel 16 and setting a reciprocating screw 18 and a moving block 19 inside the glue dispensing barrel 16, the glue pushing block 21 can evenly apply the glue in the glue dispensing barrel 16 between the lens and the bottom shell of the illuminator. Compared with traditional continuous gluing, this method not only makes the glue coating more uniform, but also requires less glue and will not easily cause glue overflow.

[0029] Embodiment 2

[0030] Based on the first embodiment, please refer to the base frame 1-4 of Figures, an electronic packaging structure for a semiconductor lighting device, wherein a straight rod 4 and a threaded rod 3 are provided on the inner wall of the mounting plate 2, the straight rod 4 is fixedly mounted on the inner wall of the mounting plate 2, and the threaded rod 3 is rotatably mounted on the inner wall of the mounting plate 2.

[0031] Furthermore, the movable frame 11 is threadedly connected to the outer wall of the threaded rod 3, and a through groove compatible with the movable frame 11 is opened on the top surface of the base frame 1. The movable frame 11 can be slidably mounted on the outer wall of the straight rod 4. By arranging the threaded rod 3 and the straight rod 4, and arranging the movable frame 11 to be threadedly connected to the outer wall of the threaded rod 3 and slidably mounted on the outer wall of the straight rod 4, the movable frame 11 can be moved while being limited, so that the movement is more stable.

[0032] In addition, a square through groove is provided on the top surface of the base frame 1, and a support rod 6 is slidably installed in the square through groove, and a telescopic cylinder 7 is fixedly installed on the top surface of the support rod 6. The support rod 6 is connected to the bottom of the telescopic cylinder 7, and a turning handle is connected to one side of the threaded rod 3. By setting the square through groove, the support rod 6 can move along the square through groove, and by setting the telescopic cylinder 7, the user can control the height of the scraper 8.

[0033] In specific implementation, the sizes of illuminators are generally different, so real-time adjustments are required during the packaging process. When the user needs to adjust the position of the glue dispensing barrel 16, the user can rotate the handle connected to one side of the threaded rod 3, thereby driving the threaded rod 3 to rotate. When the threaded rod 3 rotates, the movable frame 11 threadedly connected to the outer wall of the threaded rod 3 will be driven to move, thereby completing the adjustment of the position of the glue dispensing barrel 16, so that the glue dispensing barrel 16 can always be between the lens and the bottom shell of the illuminator, and the packaging work can be carried out stably. Similarly, by setting a square slide groove, the user can adjust the position of the support rod 6, and then adjust the height of the scraper 8 through the telescopic cylinder 7, so that the scraper 8 can always fit the glue coating.

[0034] By providing the threaded rod 3 and the movable frame 11, the device can be applicable to circular illuminators of different sizes, thereby increasing the applicable scope of the device and the practicability of the device.

[0035] Working principle: the user can place the circular lighting fixture in the placement plate 5, and then start the second motor 17 to drive the placement plate 5 to rotate, so that the circular lighting fixture starts to rotate, and at the same time start the glue pump and the first motor 12. After the glue pump is started, the glue is transferred to the glue dispensing barrel 16 through the glue pipe 10. After the first motor 12 is started, the first transmission plate 13 will be driven to rotate, and the outer walls of the first transmission plate 13 and the second transmission plate 15 are simultaneously sleeved with a transmission belt 14, so the second transmission plate 15 will also rotate synchronously, and the second transmission plate 15 is fixedly connected to the reciprocating screw 18, so When the second transmission plate 15 rotates, the reciprocating screw 18 will also rotate, and the rotation of the reciprocating screw 18 will drive the moving block 19 to move up and down within the range of the reciprocating screw 18. In the process of the moving block 19 moving up and down, the glue pushing block 21 will repeatedly squeeze the glue in the glue dispensing barrel 16 out of the glue dispensing barrel 16, thereby realizing the glue dispensing work for the lighting fixture. Unlike manual application, the glue squeezed out by the glue dispensing barrel 16 is in the shape of drops and will be applied to the lighting fixture at a uniform speed. In conjunction with the scraper 8 set above the base frame 1, the drop-shaped glue can be scraped flat, thereby realizing uniform glue coating and packaging work.

[0036] The sizes of illuminators are generally different, so real-time adjustments are required during the packaging process. When the user needs to adjust the position of the glue dispensing barrel 16, the user can rotate the handle connected to one side of the threaded rod 3, thereby driving the threaded rod 3 to rotate. When the threaded rod 3 rotates, the movable frame 11 threadedly connected to the outer wall of the threaded rod 3 will be driven to move, thereby completing the adjustment of the position of the glue dispensing barrel 16, so that the glue dispensing barrel 16 can always be between the lens and the bottom shell of the illuminator, and the packaging work can be carried out stably. Similarly, by setting a square slide groove, the user can adjust the position of the support rod 6, and then adjust the height of the scraper 8 through the telescopic cylinder 7, so that the scraper 8 can always fit the glue coating area

[0037] By setting a glue dispensing barrel 16 and setting a reciprocating screw 18 and a moving block 19 inside the glue dispensing barrel 16, the glue pushing block 21 can evenly apply the glue in the glue dispensing barrel 16 between the lens and the bottom shell of the illuminator. Compared with traditional continuous gluing, this method not only makes the glue coating more uniform, but also requires less glue and will not easily cause glue overflow.

[0038] By providing the threaded rod 3 and the movable frame 11, the device can be applicable to circular illuminators of different sizes, thereby increasing the applicable scope of the device and the practicability of the device.
