[0016] Reference Figure 2 、 Figure 3 、 Figure 5 and Figure 6 The flip adaptation retention component 9 also includes a servo motor 903. The power output shaft of the servo motor 903 is connected to the rotating rod 902 through a coupling. A circular hole is provided on the side of the connecting frame 8 close to the servo motor 903, and the inside of the circular hole is movably connected to the outside of the rotating rod 902. The front end of the rotating rod 902 is fixedly connected to one side of the flip frame 901. The flip frame 901 is provided with a hole on the side away from the rotating rod 902. The inside of the hole is movably connected to a retaining rod 904. One end of the retaining rod 904 is fixedly connected to one side of the connecting frame 8. Two symmetrical telescopic electric rods 905 are fixedly connected to both sides of the interior of the flip frame 901, and the front ends of the telescopic electric rods 905 are fixedly connected to connectors 906. The front end is fixedly connected to the outer side of the adaptive retaining member 912, and the adaptive retaining member 912 is provided with a through-hole, and the inside of the through-hole is movably connected to the round rod 907, and the two ends of the round rod 907 are fixedly connected to the inner side of the front end of the connecting member 906, and a telescopic rod 908 is provided between the symmetrical telescopic electric rods 905, and the bottom end of the telescopic rod 908 is fixedly connected to the inner sides of the flip frame 901, and the inner sides of the flip frame 901 are fixedly connected with compression springs 909, and the compression springs 909 are located on the outer side of the telescopic rod 908. The front ends of the telescopic rod 908 and the compression spring 909 are fixedly connected to the mounting member 910, and the front end of the mounting member 910 is fixedly connected to the opposite side of the symmetrical flexible arc plate 911.

[0017] Specifically, when the LED chip is flip-chip packaged, the flip frame 901 is in the initial position. When the LED chip is placed in the specified position, the telescopic electric rod 905 starts to extend, driving the front connecting piece 906 and the adaptive retaining piece 912 connected thereto to move toward the LED chip. As the telescopic electric rod 905 continues to extend, the two symmetrical adaptive retaining pieces 912 gradually approach the outside of the LED chip. If the LED chip is rectangular, the adaptive retaining pieces 912 tightly fit and clamp the outside of the LED chip. If the LED chip is circular, the flexible arc plate 911 can be fine-tuned according to the shape of the chip, and the adaptive retaining piece 912 rotates the angle to ensure that the clamping is firm and the chip is not damaged. , the servo motor 903 is started, driving the rotating rod 902 to rotate. Since the front end of the rotating rod 902 is fixedly connected to one side of the flip frame 901, the flip frame 901 begins to rotate around the axis of the rotating rod 902. The retaining rod 904 moves in the hole of the flip frame 901, playing the role of auxiliary support and stabilizing the flip trajectory, preventing the flip frame 901 from offsetting during rotation. As the flip frame 901 rotates, the clamped LED chip is flipped synchronously until it completes a 180° flip and achieves a flip-chip state, preparing for subsequent packaging processes. During the process, adaptive adjustments can be made according to LED chips of different sizes and shapes, without the need for frequent replacement of fixtures, thereby improving the versatility of the equipment for multiple chips and reducing production costs.

[0019] Reference Figure 2 、 Figure 3 、 Figure 7 and Figure 8, the anti-fall component 7 also includes a connecting plate 701, one end of the connecting plate 701 is fixedly connected to the inner side of the flip frame 901, the bottom end of the connecting plate 701 is fixedly connected to the rotating motor 702, and the power output shaft of the rotating motor 702 is connected to the rotating shaft 703 through a coupling, the inner side of the rotating shaft 703 is movably connected to a pulling rope 704, and the end of the pulling rope 704 away from the rotating shaft 703 is fixedly connected to a base 705, and the inner side of the base 705 is fixedly connected to the outer side of the connecting air pipe 707, and the bottom The top of the seat 705 is fixedly connected to the bottom of the air head 706, and a sliding plate 710 is fixedly connected to one side of the base 705. A sliding rod 711 is movably connected between the inner side of the end of the sliding plate 710 away from the base 705. Both ends of the sliding rod 711 are fixedly connected to a sliding frame 712, and the top of the sliding frame 712 is fixedly connected to the bottom of the flip frame 901. The outer side of the air pump 708 is fixedly connected to a retaining frame 709, and the top of the retaining frame 709 is fixedly connected to the bottom of the flip frame 901.

[0020] Specifically, before flipping the LED chip, after the flip adaptation retaining assembly 9 firmly clamps the LED chip, the rotating motor 702 is started to drive the rotating shaft 703 to rotate. When the rotating shaft 703 rotates, the pulling rope 704 wrapped around its inner side begins to retract and release, and the pulling rope 704 pulls the base 705, and the base 705 drives the air head 706 and the connecting air pipe 707 to move. The sliding plate 710 on one side of the base 705 slides on the sliding rod 711, and the sliding frame 712 is fixed to the bottom end of the flip frame 901 to play a guiding and stabilizing role, ensuring that the air head 706 can move smoothly and accurately to the bottom of the LED chip. After reaching the appropriate position directly below the LED chip, the air pump 708 is started. The air pump 708 delivers gas to the air head 706 through the connecting air pipe 707, so that the air head 706 generates suction. The air head 706 relies on the suction to tightly absorb the bottom of the LED chip, providing protection to prevent the chip from falling during the subsequent flipping process. Cooperating with the flip-adaptive retention component 9, the stability of the LED chip in the entire flip-chip packaging operation is ensured. During the process, the air head 706 can be accurately controlled to move to the appropriate position below the chip to ensure stable and reliable adsorption, ensure the accuracy of the entire flip-chip packaging process, greatly reduce the risk of the chip falling during flipping and other operations, and avoid chip damage and packaging failure.

[0021] A method for using a packaging structure for a flip-chip LED chip, using the packaging structure for a flip-chip LED chip as described above, comprises the following steps: Step 1: Place the LED chip with the front side facing up on top of the lifting seat 10. At this time, activate the hydraulic rod 13, which is symmetrically connected to the top of the mounting plate 6, pushing the mounting plate 6 down, thereby driving the connecting frame 8 connected to it to move down synchronously. The flip adaptive retaining assembly 9 inside the connecting frame 8 begins to operate. The two symmetrical adaptive retaining members 912 in the flip frame 901 gradually approach and accurately clamp the outer side of the LED chip, ensuring that the chip is firmly positioned during subsequent operations; Step 2: After the clamping is completed, the hydraulic rod 13 reverses and starts to rise. At the same time, the anti-drop component 7 located below the flip-adaptive retention component 9 comes into play. The air pump 708 delivers gas to the air head 706 through the connecting air pipe 707, so that the air head 706 generates suction, firmly sucking the bottom of the LED chip to prevent the chip from falling during the flipping process, providing reliable protection for the next flipping step; Step 3: After the air head 706 firmly adsorbs the bottom of the LED chip, the flip-adaptive retaining component 9 starts to perform the flipping action, driving the clamped LED chip to flip 180 degrees, turning the original front-facing LED chip to the back-facing side, preparing for the final packaging process.
