[0029] After the semiconductor chip is clamped by the roller 11, the positioning block 15 is rotated so that the positioning block 15 can squeeze the semiconductor chip to move, and the semiconductor chip is centered, so that the center position of the semiconductor chip is aligned with the glue dispensing nozzle of the glue dispensing device 4, and precise glue dispensing is performed to prevent glue from dripping on the edge of the semiconductor chip, affecting the packaging effect and reducing product quality.

[0030] And through the setting of the roller 11, when the positioning block 15 squeezes the semiconductor chip to center it, the semiconductor chip will move on the roller 11, thereby facilitating the movement of the semiconductor on the positioning plate 8 and preventing direct contact with the semiconductor chip through the positioning plate 8, thereby preventing excessive friction from causing damage to the semiconductor chip.

[0031] When this embodiment is working: when it is necessary to perform glue dispensing and packaging operations on semiconductor chips, the servo motor is started to rotate the conveyor belt, and the semiconductor chips to be packaged are placed on the conveyor belt. The semiconductor chips are transported to the glue dispensing device 4 through the conveyor belt, which is convenient for loading the semiconductor chips. When the semiconductor chips are transported to the glue dispensing device 4, the cylinder 5 is started to drive the connecting plate 6 to move, and the connecting plate 6 drives the connecting column 7 and the positioning plate 8 to move, so that the two sets of positioning plates 8 are close to each other. The rollers 11 on the positioning plate 8 can clamp and position the semiconductor chips on the conveyor belt, and the semiconductor chips are placed in the middle of the conveyor belt. When the roller 11 presses and positions the semiconductor body, the positioning plate 8 is pressed and moved toward the connecting plate 6 by the pressing force, so that the pressing spring 10 is stretched and deformed. When the positioning plate 8 is moved toward the connecting plate 6, the pressing rod 14 is brought into contact with the rotating block 13. When the pressing rod 14 presses the rotating block 13, the rotating block 13 is rotated, so that the rotating rod 12 drives the four positioning blocks 15 to rotate relative to each other, so that the torsion spring 16 is compressed and deformed, so that the positioning block 15 can press the semiconductor chip that is not centered, so that the semiconductor chip can adjust its position on the positioning plate 8. When the rotating block 13 is pressed and rotated 90° by the pressing rod 14, The positioning block 15 is rotated 90 degrees, so that the side wall of the positioning block 15 fits with the outer wall of the semiconductor chip, and the position of the semiconductor chip can be accurately positioned, so that the center position of the semiconductor chip is aligned with the dispensing nozzle of the dispensing device 4, so as to perform precise dispensing and improve the quality of product packaging. When the positioning block 15 is rotated, the inclined block 17 moves away from the side of the positioning block 15 and fits the conveyor belt. The semiconductor chip can be scooped up from the bottom of the semiconductor chip by the inclined block 17, so that the bottom of the semiconductor chip does not contact the conveyor belt, thereby reducing the friction between the semiconductor chip and the conveyor belt and reducing the risk of damage to the semiconductor chip. And when the semiconductor chip is positioned, the glue dispensing equipment 4 is started to perform the glue dispensing operation. When the glue dispensing is completed, the cylinder 5 is started to make the two groups of positioning plates 8 move away from each other so that the clamping positioning of the semiconductor chip can be released. When the positioning plate 8 is not squeezed, the clamping spring 10 is in a tensile deformation state, which will cause the clamping spring 10 to drive the stopper 9 and the connecting column 7 to reset, so that the positioning plate 8 is reset away from the connecting plate 6, so that the squeezing rod 14 does not squeeze the rotating block 13. Because the torsion spring 16 is in a contraction deformation state, the torsion spring 16 drives the positioning block 15 to rotate, and the positioning block 15 rotates to the bottom of the positioning plate 8 to perform the next positioning operation.

[0034] By starting the vacuum cleaner 1807, the next semiconductor chip that needs glue dispensing can be vacuumed through the dust hood 1808 to prevent dust from adhering to the semiconductor chip. The dust may contaminate the glue dispensing material and affect the quality and performance of the package.

The transmission rod 1811 drives the transmission block 1812 to move upward, so that the return spring 1813 is stretched, and the transmission block 1812 squeezes the hinge rod 1814, so that the hinge rod 1814 rotates at the hinge, so that the hinge rod 1814 squeezes the L-shaped squeezing block 1815 to approach the vacuum cleaner 1807, so that the L-shaped squeezing block 1815 squeezes the spring switch 1816, so that the spring switch 1816 moves to turn on the vacuum cleaner 1807, so that the dust collection operation is performed through the dust cover 1808, and the dust attached to the top of the semiconductor chip at the baffle 1805 is vacuumed, and the absorbed dust is discharged to the dust collection box. 1809, and when the baffle 1805 moves upward, the transmission rod 1811 will not be squeezed, and the reset spring 1813 will be in a stretched state, which will move the transmission block 1812 downward, causing the transmission block 1812 to pull the hinged rod 1814, causing the hinged rod 1814 to rotate at the hinge, thereby causing the hinged rod 1814 to pull the L-shaped extrusion block 1815 away from the spring switch 1816, so that the L-shaped extrusion block 1815 does not contact the spring switch 1816, and the spring switch 1816 is reset, thereby turning off the vacuum cleaner 1807 and stopping the vacuuming operation to prevent the vacuum cleaner from being in the on state all the time, which may cause power loss.

[0038] When the long board 1804 moves downward, the dust box 1809 can be driven to move downward, so that the fixed rod 1901 pulls the movable rod 1902, so that the movable rod 1902 rotates at the hinge, so that the movable rod 1902 pulls the connecting block 1903 to move toward the long board 1804, so that the connecting block 1903 drives the collecting box 1904 to move toward the long board 1804, so that the collecting box 1904 does not block the glue dispensing nozzle of the glue dispensing device 4, so that the glue dispensing operation can be performed, and when the connecting block 1 When the push block 1903 approaches the long plate 1804, the push block 1907 contacts the fixed rod 1901, so that the push block 1907 is subjected to an extrusion force, and the guide rod 1905 moves in the connecting block 1903, and the connecting spring 1906 is compressed. When the push block 1907 moves, the push rod 1908 squeezes the inclined rod 1909, and the inclined rod 1909 rotates at the hinge, so that the inclined rod 1909 squeezes the two sets of sealing plates 1910 closer to each other, and the sealing plates 1910 can be used to The top of the collecting box 1904 is sealed to prevent dust. When the dispensing operation is not performed, the long plate 1804 will move upward, thereby moving the dust collecting box 1809 upward, moving the fixed rod 1901 upward, and causing the fixed rod 1901 to squeeze the movable rod 1902, so that the movable rod 1902 squeezes the connecting block 1903 away from the long plate 1804. When the connecting block 1903 is away from the long plate 1804, the pushing block 1907 does not contact the fixed rod 1901, thereby causing the pushing block 1907 to move upward. Block 1907 is not subjected to extrusion force, and because the connecting spring 1906 is in a compressed state, the push block 1907 is reset, and the push block 1907 drives the push rod 1908 to reset, so that the push rod 1908 pulls the inclined rod 1909, and the inclined rod 1909 rotates at the hinge, so that the inclined rod 1909 pulls the two sets of sealing plates 1910 to open, and the connecting block 1903 drives the collection box 1904 to move to the bottom of the dispensing nozzle of the dispensing device 4, so that the glue dripping in the dispensing nozzle can be collected.
