[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A laser debonding machine, such as Figures 1-5As shown, the device includes a main body 1. Several feeding ports 3 are provided on the outer wall of the main body 1. Conveyor tables 2 are fixedly connected to the outer wall of the main body 1 at the lower edge of the feeding ports 3. A bearing plate 4 is fixedly connected to the outer wall of the main body 1 near the bottom. A transverse groove is provided through the upper surface of the bearing plate 4. A reciprocating screw 5 is rotatably connected inside the transverse groove. A movable block 6 is sleeved on the outside of the reciprocating screw 5. An installation plate 7 is fixedly connected to the upper end of the movable block 6. An installation seat 8 is rotatably connected to the upper surface of the installation plate 7 via a shaft. A robotic arm 9 is rotatably connected to the installation seat 8 via a shaft. A robotic arm 10 is rotatably connected to one end of the robotic arm 9 via a shaft. A fixing plate 11 is fixedly connected to the end of the robotic arm 10 away from the robotic arm 9. A clamping plate 12 and a clamping plate 25 are slidably connected to the bottom surface of the fixing plate 11.

[0026] The bottom surface of the fixed plate 11 is rotatably connected to two double-ended threaded rods 23, and the first clamping plate 12 and the second clamping plate 25 are movably sleeved on the outside of the two double-ended threaded rods 23. Two motors 2 are installed on the outer wall of the fixed plate 11, and the output ends of the two motors 2 are respectively connected to the two double-ended threaded rods 23.

[0027] In use, robotic arms 19 and 10 move the fixing plate 11 to the position of the neatly stacked wafer chip pile, so that clamping plates 12 and 25 are located on both sides of the wafer chip pile. Then, motor 2 drives the double-headed threaded rod 23 to rotate, so that clamping plates 12 and 25 move closer to each other to clamp the wafer chip pile. Each insert plate 13 is inserted between the two stacked wafer chips, so that multiple wafer chips can be clamped at one time, and the wafer chips are clamped in layers so that the wafer chips do not interfere with each other.

[0028] Motor 1 is installed on the outer wall of the bearing plate 4, and the output end of motor 1 is connected to the reciprocating screw 5. Motor 2 is installed on the outer wall of the mounting base 8, and the output end of motor 2 is connected to the robotic arm 9. Motor 3 is installed on the outer wall of robotic arm 9 at the end away from the mounting base 8, and the output end of motor 3 is connected to the robotic arm 10. Motor 4 is installed on the bottom surface of the mounting plate 7, and the output end of motor 4 is connected to the mounting base 8. Motor 2 can drive one end of robotic arm 9 to rotate, and motor 3 can drive one end of robotic arm 10 to rotate, thereby flexibly adjusting the positions of the fixing plate 11, clamping plate 12 and clamping plate 25.

[0029] Specifically, after clamping, the motor on the bottom of the mounting plate 7 drives the mounting base 8 to rotate, which in turn drives the robotic arm 9 and robotic arm 10, as well as the fixing plate 11, to rotate. This causes the clamped wafer chip to rotate closer to the conveyor 2. The motor then drives the reciprocating screw 5 to rotate, which in turn moves the movable block 6 within the transverse groove. Together with the robotic arm 9 and robotic arm 10, the clamped wafer chip can be moved sequentially to the top of each conveyor 2, allowing multiple wafer chips to be placed continuously at once, increasing the loading speed and thus improving the processing efficiency of the wafer chip.

[0030] Several insert plates 13 are movably inserted into the outer walls of both clamp plate 12 and clamp plate 25. Two L-shaped connecting plates 14 are fixedly connected to the outer walls of both clamp plate 12 and clamp plate 25. Several sliding grooves are opened through the outer walls of the two L-shaped connecting plates 14. Sliding rods 15 are fixedly connected inside the sliding grooves. Sliding sliders 16 are sleeved on the outside of the sliding rods 15. One end of the sliding slider 16 is fixedly connected to the insert plate 13. A return spring is sleeved on the outside of the sliding rod 15 and located between the sliding slider 16 and the inner wall of the sliding groove. One end of the return spring is fixedly connected to the sliding slider 16, and the other end of the return spring is fixedly connected to the inner wall of the sliding groove. The initial state is a stretched state.

[0031] Both L-shaped connecting plates 14 have electric telescopic rods 17 installed on their inner walls. A push plate 18 is fixedly connected to one end of each electric telescopic rod 17. Two threaded screws 20 are rotatably connected to the outer walls of clamping plate 12 and clamping plate 25. L-shaped sliding plates 21 are fitted over each of the two threaded screws 20, and a stop bar 19 is fixedly connected between the two L-shaped sliding plates 21. Two motors 1 are installed on the bottom surfaces of clamping plate 12 and clamping plate 25, and the output ends of the two motors 1 are respectively connected to the two threaded screws 20. After a set of wafer chips is placed, the electric telescopic rods... The retractor 17 drives the pusher 18 to move, which can push each insert plate 13 to the initial position. At this time, the motor drives the threaded screw 20 to reverse, which drives the stop bar 19 to move down, which can re-block and limit the position of each insert plate 13. The L-shaped slide plate 21 and the threaded screw 20 are fitted with threads that fit with the threaded screw 20. When the threaded screw 20 rotates, the L-shaped slide plate 21 can be vertically displaced under the cooperation of the threads. Similarly, the clamping plate 12 and the clamping plate 25 can be horizontally displaced when the double-headed threaded rod 23 rotates.

[0032] Specifically, when the clamped wafer chip is moved to the conveyor 2, the screw 20 can be rotated by the motor to move the L-shaped slide plate 21 upward, thereby moving the stop bar 19 upward and releasing the obstruction of the bottom insert plate 13. At this time, under the action of the return spring, the slider 16 moves along the slide groove, moving the insert plate 13 into the L-shaped connecting plate 14, releasing the load limit on the bottom wafer chip. Under the action of gravity, the bottom wafer chip automatically falls onto the conveyor 2. Similarly, the remaining wafer chips are moved to the next conveyor 2, and the load on the wafer chip is released from the next insert plate 13. The wafer chips can be placed on each conveyor 2 in sequence, and finally enter the main body 1 through the feeding port 3 for processing.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
