[0050] The discharging assembly comprises a push plate 11 arranged at the top end of the workbench 1, the push plate 11 is arranged at one side of the tray 4, and the bottom end of the push plate 11 is installed on the outer wall of the threaded rod 7.

[0051] The existing CN216849850U discloses a chip packaging device based on information technology control, which discloses a workbench, a top plate, a packaging device and a chip tray plate, and the workbench 1, the top plate 2, the packaging structure 3, the tray 4 and the specific packaging mode in the present application file all adopt the same technical means as in the prior art, which will not be described here.

[0052] Through the cooperation of the feeding assembly and the discharging assembly, when the chip is packaged, first, the tray 4 carrying the chip is placed on one side of the push plate 11, so that the side wall of the tray 4 is attached to the side wall of the push plate 11, then the threaded rod 7 is driven to rotate by the motor 8, the rotation of the threaded rod 7 drives the movement of the push plate 11, so that the push plate 11 pushes the tray 4 to the direction of the positioning seat 5, and then the tray 4 moves to the lower side of the packaging structure 3, and then the push plate 11 is moved back to the original position by reversing the threaded rod 7, and finally the chip on the top of the tray 4 is packaged by the packaging structure 3.

[0053] When packaging, another tray 4 can be placed on the side wall of the push plate 11, and when the chip in the tray 4 below the packaging structure 3 is packaged, the threaded rod 7 is driven to rotate by the motor 8 again, the rotation of the threaded rod 7 drives the movement of the moving seat 6, the movement of the moving seat 6 drives the movement of the positioning seat 5, so that the two positioning seats 5 clamp the tray 4 with the packaged chip and move away, and then the push plate 11 pushes the new tray 4 to the lower side of the packaging structure 3 for packaging.

[0054] The device drives the positioning seat 5 and the push plate 11 to move synchronously by the rotation of the threaded rod 7, so that the tray 4 is fed and discharged, the feeding and discharging efficiency is improved, the operation process of the workers is simplified, and the overall efficiency of the chip packaging is improved.

[0056] The magnetic block 14 and the magnetic plate 19 are magnetically connected;

[0057] The initial position of the magnetic block 14 is above the magnetic plate 19, and the two are staggered;

[0058] When the positioning seat 5 clamps the tray 4 to move to unload, the movement of the positioning seat 5 drives the movement of the connecting block 13, the movement of the connecting block 13 drives the movement of the magnetic block 14, when the magnetic block 14 moves to one end of the wedge block 18, the magnetic block 14 is pressed downward through the inclined surface guidance of the wedge block 18, so that the magnetic block 14 is parallel to the magnetic plate 19, and the magnetic force between the two makes the magnetic block 14 move to one side of the magnetic plate 19 and adhere, at the same time, the movement of the magnetic block 14 drives the movement of the connecting block 13, the movement of the connecting block 13 drives the movement of the positioning seat 5 through the connecting shaft 15, so that the positioning seat 5 moves a distance away from the tray 4, so that the two positioning seats 5 clamp the tray 4 to move to the unloading area and then release the tray 4;

[0059] The magnetic plate 19 is located on the left side of the positioning seat 5, and the length of the magnetic plate 19 is slightly shorter than the distance of the left movement of the positioning seat 5, so that the positioning seat 5 keeps the state of outward opening when it moves right to reset.

[0060] As shown in Figure 9 and Figure 10 , the top end of the connecting block 13 is fixedly connected with the connecting shaft 15, the top end of the connecting shaft 15 is fixedly installed with the limiting plate 16, the limiting plate 16 is slidingly installed in the inside of the positioning seat 5, and the second spring 17 is arranged between the limiting plate 16 and the positioning seat 5.

[0061] When the magnetic block 14 is guided downward through the wedge block 18, the movement of the magnetic block 14 drives the movement of the connecting shaft 15, the movement of the connecting shaft 15 drives the movement of the limiting plate 16, and the downward movement of the limiting plate 16 makes the second spring 17 deform to store elastic potential energy, when the magnetic block 14 moves away from the magnetic plate 19, the elastic potential energy of the second spring 17 is released to drive the upward movement of the limiting plate 16, so that the magnetic block 14 moves upward to reset.

[0063] When the magnetic block 14 is connected with the magnetic plate 19 to drive the positioning seat 5 to move away from the side of the tray 4, the positioning seat 5 is simultaneously slid on the outer wall of the limiting rod 9, so that the first spring 10 is deformed to store elastic potential energy, and when the magnetic block 14 is separated from the magnetic plate 19, the elastic potential energy is released through the first spring 10 to drive the positioning seat 5 to move to the side of the tray 4 to reset, so that the two positioning seats 5 are moved inward after moving to the lower side of the packaging structure 3 to clamp the tray 4, which can not only ensure the stability during discharging, but also improve the stability of the chips on the top of the tray 4 during processing.

[0064] As shown in Figure 1 , Figure 2 and Figure 11 , the top end of the workbench 1 is fixedly provided with a guide plate 12, and the guide plate 12 is symmetrically provided with two.
