Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1:

[0020] See also Figures 1 to 8 As shown, a LED packaging adhesive coating device includes: Workbench 1; A support frame 2 is installed on one side of the top of the workbench 1, a coating mechanism 3 is installed between the inner walls of both sides of the support frame 2, a packaging glue box 4 is installed on the top of the support frame 2, two fixing mechanisms 5 are placed in the middle of the top of the workbench 1, and a curing mechanism 6 is installed on the other side of the top of the workbench 1; The coating mechanism 3 includes a fixed frame 31, a scraper plate 32, an adjustment mechanism 33, a distance sensor 34, a coating roller 35, a shunt pipe 36, a rubber delivery pipe 37 and a material extraction pump 38.

[0021] Depend on Figures 1 to 4It can be seen that a purifier 7 is installed on one side of the outer wall of the curing mechanism 6, a controller 8 is installed on the other side of the outer wall of the curing mechanism 6, support frames 9 are installed on both sides of the bottom of the workbench 1, two limit grooves 10 are opened on the top of the workbench 1, and protective covers 11 are installed between the support frame 2 and the inner walls on both sides of the curing mechanism 6; The adjustment mechanism 33 includes a forward and reverse screw rod 331, a moving rod 332, a driver 333, a limit rod 334 and an adjustment rod 335. The forward and reverse screw rod 331 is installed between the inner walls on both sides of the support frame 2 through a bearing. Two moving rods 332 are provided. The two moving rods 332 are respectively installed on both sides of the outer surface of the forward and reverse screw rod 331. The driver 333 is installed at one end of the forward and reverse screw rod 331. The limit rod 334 is installed between the opposite surfaces of the two moving rods 332.

[0022] As can be seen from the above, after the entire coating device is started by the controller 8, the extraction pump 38 starts to work, extracts the packaging glue from the packaging glue box 4, and inputs it into the shunt pipe 36 through the glue delivery pipe 37, and evenly delivers it to the coating roller 35. At the same time, the distance sensor 34 measures the distance between the coating roller 35 and the LED chip, and feeds the data back to the controller 8. The controller 8 controls the driver 333 to start according to these data, so that the positive and negative screw rods 331 drive the two moving rods 332 thereon to move toward the middle, and then pushes the fixed frame 31 downward through the adjustment rod 335 to expand the glue delivery pipe 37. The folding part of the LED chip is adjusted to adjust the position of the coating roller 35 so that it contacts the LED chip.

The coating device can adjust the position of the coating roller 35 in real time according to the thickness of the LED chip, keep the spacing with the LED chip consistent, and ensure the uniformity and consistency of the coating glue layer. Therefore, the device can batch coat LED chips of different thicknesses, which is suitable for batch production and meets the needs of large-scale production.

[0024] As can be seen from the above, these devices can be controlled and coordinated by the controller 8, so that the scraper 32 can evenly coat the packaging glue on the coating roller 35, ensuring that the coating roller 35 can completely cover the LED chip clamped in the clamping frame 551, so that the glue delivery tube 37 can flexibly adapt to different working positions while maintaining the smoothness of glue delivery. Embodiment 2:

[0025] refer to Figures 5 to 7 As shown, the outer walls of the two protective covers 11 are both mounted with motors 12, the output ends of the two motors 12 are both mounted with double pulleys 13, the two double pulleys 13 are respectively mounted on the inner walls of the two protective covers 11 through bearings, the inner walls on both sides of the two protective covers 11 are both mounted with driving rods 14 through bearings, a single pulley 15 is mounted on one side of the outer surface of the four driving rods 14, a synchronous belt 16 is commonly sleeved between the single pulley 15 and the double pulley 13, and a gear 17 is mounted on the other side of the outer surface of the four driving rods 14; The fixing mechanism 5 includes a fixing plate 51, a limiting bar 52, a handle 53, a tooth groove 54 and a clamping mechanism 55. The fixing plate 51 is placed on the top of the workbench 1. Two limiting bars 52 and two handles 53 are provided. The two limiting bars 52 are installed at the bottom of the fixing plate 51. The two handles 53 are installed at both ends of the fixing plate 51. There are a plurality of tooth grooves 54 and a plurality of clamping mechanisms 55. The plurality of tooth grooves 54 are respectively opened on both sides of the top of the fixing plate 51. The plurality of clamping mechanisms 55 are installed in the middle of the top of the fixing plate 51. The clamping mechanism 55 includes a clamping frame 551, a guide groove 552, an electric telescopic rod 553, a guide block 554, a storage cavity 555, a spring 556 and a clamping rod 557. The clamping frame 551 is installed at the top of the fixed plate 51. There are two guide grooves 552, two electric telescopic rods 553 and two guide blocks 554. The two guide grooves 552 are respectively opened at both ends of the clamping frame 551. The two electric telescopic rods 553 are respectively installed on the outer walls of both sides of the clamping frame 551. The two guide blocks 554 are respectively installed on the opposite surfaces of the two electric telescopic rods 553. There are a plurality of storage cavities 555, a plurality of springs 556 and a clamping rod 557.

A plurality of springs 556 are respectively installed on the inner walls of a plurality of storage cavities 555. A plurality of clamping rods 557 are respectively installed on the other ends of a plurality of springs 556.

[0026] As can be seen from the above, first, the LED chip to be coated is placed in the clamping frame 551, and then the electric telescopic rod 553 is started, which pushes the guide block 554 to the middle, and the guide groove 552 guides and limits the guide block 554, thereby improving stability, thereby ensuring that the plurality of clamping rods 557 can stably contact and clamp the LED chip. At this time, the elastic action of the plurality of springs 556 enables each clamping rod 557 to contact the LED chip, and the telescopic function of the clamping rod 557 can adapt to LED chips of different shapes, thereby facilitating the firm fixation of LED chips of different shapes and sizes. This design meets the needs of diversified In order to meet the needs of the product and improve the production efficiency, after the multiple clamping mechanisms 55 on the fixing plate 51 have fixed the LED chips, the limiting strip 52 on the fixing plate 51 is inserted into the limiting groove 10, and then the motor 12 is started to drive the double pulley 13 to rotate, and the single pulley 15 driven by the synchronous belt 16 also rotates accordingly, which causes the driving rod 14 to drive the gear 17 to rotate, and the meshing transmission between the gear 17 and the plurality of tooth grooves 54 enables the fixing plate 51 to drive the LED chips to move to the bottom of the coating mechanism 3 for batch coating. In addition, this design also facilitates the transportation of the LED chips coated with the packaging glue to the curing mechanism 6 for curing.

[0027] Preferably, reference Figures 5 to 7 As shown, the electric telescopic rod 553 and the motor 12 are both electrically connected to the controller 8 , positioning protrusions are provided at both ends of the guide block 554 , the clamping rod 557 is configured as an I-shaped structure, and the gear 17 is meshed with a corresponding number of tooth grooves 54 .

[0028] As can be seen from the above, the electric telescopic rod 553 and the motor 12 are both controlled by the controller 8. The positioning protrusion on the guide block 554 slides with the guide groove 552 to limit the position of the guide block 554. The I-shaped clamping rod 557 will not be separated from the storage cavity 555, and can also increase the contact area with the LED chip. The meshing design of the gear 17 and the tooth groove 54 realizes the transmission function and can be used to adjust the position of the fixed plate 51. Embodiment three:

[0029] refer to Figure 8As shown, the curing mechanism 6 includes a curing box 61, an inlet and outlet 62, an electric push rod 63, an adjustment frame 64, a distance sensor 65 and a curing lamp 66. The curing box 61 is installed at the top of the workbench 1. Two inlets and outlets 62 are provided. The two inlets and outlets 62 are respectively opened at the lower parts of the two ends of the curing box 61. There are a plurality of electric push rods 63, adjustment frames 64, distance sensors 65 and curing lamps 66. A plurality of electric push rods 63 are installed at the top of the curing box 61, a plurality of adjustment frames 64 are respectively installed at the bottom ends of a plurality of electric push rods 63, a plurality of distance sensors 65 are respectively installed at the middle parts of the bottom ends of a plurality of adjustment frames 64, and a plurality of curing lamps 66 are respectively installed between the inner walls on both sides of a plurality of adjustment frames 64.

[0030] As can be seen from the above, when the fixing mechanism 5 transports the LED chip coated with packaging glue to the curing box 61, the ultraviolet light emitted by the curing lamp 66 will irradiate the packaging glue coated on the LED chip, thereby accelerating the curing speed of the packaging glue. At the same time, the distance sensor 65 can monitor the distance between the LED chip and the distance sensor 65 in real time, and drive the electric push rod 63 according to the detected data. After the electric push rod 63 is extended, it pushes the adjustment frame 64 to move downward, and then the adjustment frame 64 drives the curing lamp 66 to adjust its position. This not only shortens the curing time, but also ensures that the curing effect of the packaging glue is optimal, ensuring that the glue can receive sufficient light energy, thereby improving work efficiency. In addition, the purifier 7 will extract and purify the gas in the curing box 61 to improve safety.

[0031] Preferably, reference Figure 8 As shown, the electric push rod 63 , the distance sensor 65 and the curing lamp 66 are all electrically connected to the controller 8 , the adjustment frame 64 is configured as a Japanese-shaped structure, and the outer walls of the adjustment frame 64 on both sides are in contact with the inner walls of the curing box 61 on both sides.

[0032] As can be seen from the above, the controller 8 can realize the control and coordination of these devices, the adjustment frame 64 of the Chinese-Symbol-shaped structure provides a stable supporting structure, and the contact design between the adjustment frame 64 and the curing box 61 plays a limiting role, thereby improving the stability of the adjustment frame 64.

[0033] Application examples: The present design is applied in the environment of semiconductor manufacturing and LED packaging production line. By setting up the coating mechanism 3, the distance sensor 34 on the mechanism can measure the distance between the coating roller 35 and the LED chip in real time, and the adjustment mechanism 33 dynamically adjusts the position of the coating roller 35 according to the feedback of the distance sensor 34 to ensure the uniformity and consistency of the coating layer. At the same time, with the mobile control of the LED chip by the fixing mechanism 5, batch coating of the LED chips can be realized, thereby improving the production efficiency. The design of the fixing mechanism 5 enables it to adapt to LED chips of different shapes and sizes, meet the needs of diversified products, and ensure the firm fixation of the LED chip. In addition, by setting up the curing mechanism 6 and adopting the ultraviolet irradiation method of the curing lamp 66, the curing process of the packaging glue is accelerated, and the curing time is further shortened by adjusting the position of the curing lamp 66 in real time.
