Description
Technical Field
[0001] The present invention relates to the technical field of semiconductor chip packaging, and particularly to a semiconductor chip packaging device convenient for feeding. Background Art
[0002] Semiconductors refer to materials with electrical conductivity between conductors and insulators at room temperature. Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. Most electronic products, such as the core chips in computers, mobile phones or digital recorders, are extremely closely related to semiconductors. After etching and wiring on semiconductor wafers, semiconductor chips capable of realizing certain functions are made. After the chips are manufactured, they need to be packaged.
[0003] The patent with the patent announcement number CN220420538U relates to a dispensing device for semiconductor chip packaging, including a device main body. An operation terminal is fixedly connected to the side of the device main body. An installation bracket is fixedly connected to the outer side wall of the upper end of the device main body. A moving slide rail is provided on the installation bracket. A dispensing pen is slidably connected to the moving slide rail. An installation tube is installed at the upper end of the dispensing pen. Through the setting of the stirring tank, when in use, the colloid can be first injected into the stirring tank and pretreated by the stirring blades. In this way, the colloid is defoamed by the uniform stirring of the stirring blades, avoiding the phenomenon of holes when the colloid is injected. At the same time, when the stirring blades stir the colloid in the stirring tank, the conditioning member on the stirring blades will automatically release a diluent to condition the colloid, avoiding the colloid from being too viscous and causing phenomena such as wire drawing during subsequent dispensing.

Detailed implementation manners
[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0028] Please refer toFigures 1-5 An embodiment of the present invention is: a semiconductor chip packaging device convenient for feeding, including a support base 1 and a conveying device 2. The conveying device 2 is arranged inside the support base 1. The conveying device 2 includes a servo motor and a conveyor belt. The conveyor belt is rotatably installed on the inner wall of the support base 1. The servo motor is fixedly penetrated through one side of the support base 1 away from the conveyor belt. The output end of the servo motor is fixedly connected to the drive shaft of the conveyor belt. A fixed frame 3 is fixed on the top of the support base 1. A dispensing device 4 is arranged on the fixed frame 3. A positioning component for positioning the semiconductor chip is arranged on the support base 1. Among them, the positioning component includes a cylinder 5, a connecting plate 6, a connecting column 7, a positioning plate 8, a stopper 9, a compression spring 10, a roller 11, a rotating rod 12, a rotating block 13, a positioning block 15, an inclined block 17, a pressing rod 14 and a torsion spring 16. The cylinder 5 is fixed on the fixed frame 3. The output end of the cylinder 5 is fixed with a connecting plate 6. A connecting column 7 is penetrated through the connecting plate 6, and the connecting column 7 is rotatably connected to the penetration of the connecting plate 6. One end of the connecting column 7 is fixed with a positioning plate 8. The other end of the connecting column 7 is fixed with a stopper 9. A compression spring 10 is fixed on the side of the stopper 9 close to the connecting plate 6. The side of the compression spring 10 away from the stopper 9 is fixed on the side wall of the connecting plate 6. A plurality of groups of rollers 11 arranged in a linear array are rotatably installed inside the positioning plate 8. A pressing rod 14 is fixed on the side wall of the connecting plate 6. A rotating rod 12 is penetrated through the positioning plate 8, and the rotating rod 12 is rotatably connected to the penetration of the positioning plate 8. The top of the rotating rod 12 is fixed with a rotating block 13. The bottom of the rotating rod 12 is fixed with a positioning block 15. There are four positioning blocks 15, and two positioning blocks 15 are in a group. The two groups of positioning blocks 15 are symmetrically arranged with the center line in the vertical direction of the conveyor belt as the axis of symmetry. A torsion spring 16 is fixed on the top of the positioning block 15. The top of the torsion spring 16 is fixed on the inner side of the bottom of the positioning plate 8. An inclined block 17 is fixed on the side wall of the positioning block 15. The bottom of the inclined block 17 is in contact with the top of the conveyor belt.
[0029] And after the semiconductor chip is clamped by the rollers 11, through the rotation of the positioning block 15, the positioning block 15 can squeeze the semiconductor chip to move, so as to center and position the semiconductor chip, align the center position of the semiconductor chip with the dispensing nozzle of the dispensing device 4, and perform precise dispensing, preventing the glue from dripping on the edge of the semiconductor chip, affecting the packaging effect and reducing the product quality.
[0030] And through the arrangement of the rollers 11, when the positioning block 15 squeezes the semiconductor chip to center, the semiconductor chip will move on the rollers 11, which is convenient for the semiconductor to move on the positioning plate 8, preventing direct contact between the positioning plate 8 and the semiconductor chip, so that the friction force is too large and may cause damage to the semiconductor chip.
[0031] During the operation of this embodiment: When dispensing and encapsulating a semiconductor chip is required, start the servo motor to rotate the conveyor belt. Place the semiconductor chip to be encapsulated on the conveyor belt. Through the conveyor belt, transport the semiconductor chip in the direction of the dispensing device 4 to facilitate the feeding operation of the semiconductor chip. When the semiconductor chip is transported to the dispensing device 4, start the cylinder 5, which can drive the connecting plate 6 to move. The connecting plate 6 drives the connecting column 7 and the positioning plate 8 to move, making the two positioning plates 8 approach each other. The rollers 11 on the positioning plate 8 can clamp and position the semiconductor chip on the conveyor belt, and make the semiconductor chip in the middle position of the conveyor belt. After the rollers 11 press and position the semiconductor body, the positioning plate 8 will approach the connecting plate 6 under the extrusion force, stretching and deforming the compression spring 10. When the positioning plate 8 approaches the connecting plate 6, the extrusion rod 14 will contact the rotating block 13. When the extrusion rod 14 squeezes the rotating block 13, the rotating block 13 will rotate, causing the rotating rod 12 to drive the four positioning blocks 15 to rotate relative to each other, compressing and deforming the torsion spring 16, enabling the positioning blocks 15 to squeeze the non-centered semiconductor chip and adjust the position of the semiconductor chip on the positioning plate 8. When the rotating block 13 is squeezed and rotated 90° by the extrusion rod 14, the positioning block 15 rotates 90°, exactly making the side wall of the positioning block 15 fit the outer wall of the semiconductor chip, accurately positioning the position of the semiconductor chip, aligning the center position of the semiconductor chip with the dispensing nozzle of the dispensing device 4, and thus performing accurate dispensing, improving the quality of product encapsulation. When the positioning block 15 rotates, the inclined block 17 moves along the conveyor belt on the side away from the positioning block 15. The inclined block 17 can lift the semiconductor chip from the bottom of the semiconductor chip, making the bottom of the semiconductor chip 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. After positioning the semiconductor chip, start the dispensing device 4 for dispensing operation. After dispensing, start the cylinder 5 to move the two positioning plates 8 away from each other, thereby releasing the clamping and positioning of the semiconductor chip. When the positioning plate 8 is not under extrusion, since the compression spring 10 is in a stretched and deformed state, the compression spring 10 will drive the stopper 9 and the connecting column 7 to reset, causing the positioning plate 8 to move away from the connecting plate 6 and reset, so that the extrusion rod 14 does not squeeze the rotating block 13. Since the torsion spring 16 is in a contracted and deformed state, the torsion spring 16 will drive the positioning block 15 to rotate, making the positioning block 15 rotate to the bottom of the positioning plate 8 for the next positioning operation.

[0033] And by moving the baffle 1805 downward to fit with the conveyor belt, it can block the next semiconductor chip to be dispensed and encapsulated, perform intermittent feeding, prevent the occurrence of material collision, and prevent the two groups of semiconductor chips from colliding, which is likely to cause damage.
[0034] And by starting the vacuum cleaner 1807, the dust suction operation can be carried out on the next semiconductor chip to be dispensed through the dust suction hood 1808, preventing dust and the like from adhering to the semiconductor chip. Dust may contaminate the dispensing material and affect the quality and performance of the encapsulation.
[0035] The collection component includes a fixed rod 1901, a movable rod 1902, a connecting block 1903, a collection box 1904, a guide rod 1905, a connecting spring 1906, a push rod 1908, a push block 1907, an inclined rod 1909 and a sealing plate 1910; the fixed rod 1901 is fixed on the top of the dust collection box 1809, the inner bottom of the fixed frame 3 is slidably installed with a connecting block 1903, the connecting block 1903 is hinged with a movable rod 1902, one end of the movable rod 1902 away from the connecting block 1903 is hinged on the top of the fixed rod 1901, one side of the connecting block 1903 away from the movable rod 1902 is fixed with a collection box 1904, the top of the collection box 1904 is slidably installed with a sealing plate 1910, a guide rod 1905 passes through the connecting block 1903 and is slidably connected at the passing position, the end point of the guide rod 1905 is fixed with a push block 1907, the side wall of the push block 1907 is fixed with a connecting spring 1906, the side of the connecting spring 1906 away from the push block 1907 is fixed on the side wall of the connecting block 1903, the side wall of the push block 1907 is fixed with a push rod 1908, one end of the push rod 1908 away from the push block 1907 is hinged with an inclined rod 1909, one end of the inclined rod 1909 away from the push rod 1908 is hinged on the sealing plate 1910, there are two groups of sealing plates 1910, and the two groups of sealing plates 1910 are symmetrically arranged with the central line in the vertical direction of the collection box 1904 as the axis of symmetry, and the collection box 1904 can collect the excess dripping glue in the dispensing nozzle of the dispensing device 4, preventing the glue from dripping onto the conveyor belt and causing pollution to the conveyor belt, which is inconvenient for subsequent staff to clean up.
[0036] Moreover, through the setting of the two groups of sealing plates 1910, when the collection box 1904 is not performing the glue receiving operation, the sealing plates 1910 will block the top of the collection box 1904, so as to achieve the effect of dust prevention.
[0037] During the operation of this embodiment: when the two connecting plates 6 approach each other, the sliding rod 1801 will move in the inclined groove of the sliding groove 1806, thereby causing the sliding rod 1801 to squeeze the inclined groove of the sliding groove 1806. Due to the extrusion force, the long plate 1804 will move downward, so that the long plate 1804 can drive the baffle 1805 to move downward to block the next semiconductor chip to be dispensed. And when the sliding rod 1801 moves to the straight groove section of the sliding groove 1806, the position of the long plate 1804 will no longer change. And when the dispensing is completed, since the two connecting plates 6 move away from each other to release the clamping and positioning of the dispensed semiconductor chip, it can be transported to the next process through the conveyor belt. And when the two connecting plates 6 are reset, the sliding rod 1801 will be reset in the sliding groove 1806. When moving to the inclined groove section of the sliding groove 1806, it will squeeze the long plate 1804 to move upward, causing the baffle 1805 to move upward and not block the semiconductor chip, and feeding operation can be carried out. Through the setting of the baffle 1805, the effect of intermittent feeding can be achieved, thereby preventing the occurrence of material collision accidents. And when the baffle 1805 moves downward, the transmission rod 1811 will first contact the outer wall of the conveyor belt. Due to the extrusion force, the transmission rod 1811 will move upward in the baffle 1805, causing the transmission rod 1811 to drive the transmission block 1812 to move upward, stretching the return spring 1813. And the transmission block 1812 will squeeze the hinge rod 1814, causing the hinge rod 1814 to rotate at the hinge. Thus, the hinge rod 1814 squeezes the L-shaped extrusion block 1815 to approach the vacuum cleaner 1807, so that the L-shaped extrusion block 1815 squeezes the spring switch 1816 to move the spring switch 1816 to turn on the vacuum cleaner 1807. Thus, through the dust suction cover 1808, the dust suction operation is carried out to suck the dust attached to the top of the semiconductor chip at the baffle 1805, and the adsorbed dust is discharged into the dust collection box 1809. And when the baffle 1805 moves upward, the transmission rod 1811 will not be under extrusion force, and the return spring 1813 is in a stretched state, causing the transmission block 1812 to move downward, causing the transmission block 1812 to pull the hinge rod 1814, causing the hinge rod 1814 to rotate at the hinge. Thus, the hinge rod 1814 pulls 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 dust suction operation to prevent the continuous on state from easily causing power consumption.
[0038] And when the long board 1804 moves downward, it can drive the dust collection box 1809 to move downward, so that the fixed rod 1901 pulls the movable rod 1902, causing the movable rod 1902 to rotate at the hinge, and the movable rod 1902 pulls the connecting block 1903 to move towards the long board 1804. Thus, the connecting block 1903 drives the collection box 1904 to move towards the long board 1804, so that the collection box 1904 does not block the dispensing nozzle of the dispensing device 4, and thus the dispensing operation can be carried out. And when the connecting block 1903 approaches the long board 1804, the push block 1907 will contact the fixed rod 1901, so that the push block 1907 is subjected to an extrusion force, causing the guide rod 1905 to move in the connecting block 1903 and compressing the connecting spring 1906. When the push block 1907 moves, the push rod 1908 will squeeze the inclined rod 1909, causing the inclined rod 1909 to rotate at the hinge, and the inclined rod 1909 squeezes the two sets of sealing plates 1910 to approach each other. The top of the collection box 1904 can be sealed by the sealing plates 1910, achieving the effect of dust prevention. And when the dispensing operation is not carried out, the long board 1804 will move upward, so that the dust collection box 1809 will move upward, the fixed rod 1901 will move upward, and the fixed rod 1901 will squeeze the movable rod 1902, causing the movable rod 1902 to squeeze the connecting block 1903 away from the long board 1804. And when the connecting block 1903 moves away from the long board 1804, since the push block 1907 does not contact the fixed rod 1901, the push block 1907 will not be subjected to the extrusion force. And because the connecting spring 1906 is in a compressed state, the push block 1907 will be reset, causing the push block 1907 to drive the push rod 1908 to be reset, the push rod 1908 will pull the inclined rod 1909, causing the inclined rod 1909 to rotate at the hinge, and the inclined rod 1909 will pull 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 from the dispensing nozzle can be collected.
