Description

Technical Field

[0001] The utility model belongs to the technical field of integrated circuits, in particular to a device for removing glue from an integrated circuit packaging line. Background Art

[0002] During the integrated circuit packaging process, there is often a problem of glue overflow on the package end face. There are many reasons for glue overflow, such as glue overflow caused by lead frame deformation and glue overflow caused by frame belt protrusions. The existence of glue overflow on the package end face will affect the normal use of the integrated circuit package. In severe cases, it may be directly scrapped and reduce the output of the integrated circuit package.

[0003] A Chinese patent with announcement number CN211191084U discloses an insulating glue cleaning device for integrated circuit packaging, comprising a base, a pulling rod provided on the bottom surface of the base, a shaft provided at the end of the pulling rod, a roller sleeved on the outer side of the shaft, and a sleeve inserted on the plate surface of the base, and a limit rod inserted on the bottom surface of the sleeve; when working, the roller is pressed against the outer wall of the insulating circuit packaging box, the scraper is placed at the place where the insulating glue of the integrated circuit packaging box overflows, and then the hand ring is pinched and the adjusting screw is rotated downward so that the bottom end of the scraper rests on the insulating glue. During this process, the bottom end of the adjusting screw rotates inside the rotating groove, the limit rod is inserted in the guide groove to prevent the adjusting screw from disengaging from the rotating groove, and the limit rod is inserted in the bottom of the sleeve to prevent the connecting plate from rotating with the adjusting screw. The push-pull handle is held and the adjusting screw is pushed, driving the roller to slide along the integrated circuit packaging box, and the scraper cleans the overflowed insulating glue on the outer wall of the integrated circuit packaging box.

[0004] In the above technology, the overflowed glue tends to solidify after a period of time and adheres tightly to the outer wall of the packaging box. When directly removing it with a scraper, if the scraper is close to the outer wall of the packaging box, it is easy to scratch the outer wall of the packaging box; if the scraper is not close to the outer wall of the packaging box, the glue may not be cleaned completely.

[0005] Therefore, in order to solve the above problems, an integrated circuit packaging line debonding device is proposed. Utility Model Content

[0027] During operation, the overflowed glue tends to solidify after a period of time and adheres tightly to the outer wall of the packaging box. When directly cleaning with the scraper 9, if the scraper 9 is close to the outer wall of the packaging box, it is easy to scratch the outer wall of the packaging box; if the scraper 9 is not close to the outer wall of the packaging box, the glue may not be cleaned up. In order to solve the problem that the scraper 9 is inconvenient to clean the outer wall of the packaging box directly, the packaging box is fixed on the conveyor belt, and then the electric push rod 7 is turned on, and the installation box 8 is driven to move by the output end of the electric push rod 7, and the hot air pipe 10 and the scraper 9 are driven to move by the installation box 8 until the scraper 9 contacts the packaging box, and then the fan 15 and the heating tube 1 are turned on. 3. The heat fills the hot air box 12, and the heat is discharged through the hot air pipe 10 by the fan 15. At this time, the air valve 11 in the corresponding direction is opened when the scraper 9 moves. The hot air in the hot air pipe 10 melts the colloid on the surface of the packaging box.

[0031] During operation, when the packaging box needs to be fixed, the packaging box moves on the conveyor belt. When the packaging box moves to the position of the limit box 19, the conveyor belt stops moving. By opening the cylinder 17, the two cylinders 17 drive the limit box 19 through the output end to fix the packaging box. When the scraper 9 scrapes the glue, the glue flows into the limit box 19 through the penetration plate 24.

[0033] During operation, the glue flows into the limit box 19 through the permeation plate 24, and finally flows to the bottom of the limit box 19 through the guide plate 30. The suction pump 22 is turned on, and the suction pump 22 pumps the glue in the limit box 19 to the recovery box 21 through the three-way pipe 23 to recover the glue uniformly.

[0034] Further, such as Figure 4 and Figure 5 As shown, a socket 25 is provided on the top of one of the limit boxes 19; a cleaning mechanism is provided in the socket 25, and the cleaning mechanism includes two cross bars 29 fixed to the inner wall of the limit box 19, and the two cross bars 29 are slidably connected to two clamping blocks 26 through side plates 28, and the clamping blocks 26 cooperate with the scraper 9; two springs 27 are fixed between the clamping blocks 26 and the inner wall of the limit box 19.

[0035] During operation, glue adheres to the side wall of the scraper 9, which solidifies on the scraper 9 after a period of time, making the bottom of the scraper 9 uneven and inconvenient to scrape the outer wall of the packaging box. By aligning the scraper 9 with the socket 25, the scraper 9 is moved downward by the electric push rod 7 and inserted between the two clamping blocks 26. The two clamping blocks 26 move to both sides under the action of the spring 27. The clamping blocks 26 scrape the glue on the scraper 9 on the limit box 19, and then the scraper 9 moves upward. Under the action of the spring 27, the clamping blocks 26 are reset and scraper 9 is scraped again.

[0038] Working principle: in order to solve the problem that the scraper 9 is inconvenient to clean the outer wall of the packaging box directly, the packaging box is fixed on the conveyor belt, and then the electric push rod 7 is turned on, and the installation box 8 is driven to move by the output end of the electric push rod 7, and the hot air pipe 10 and the scraper 9 are driven to move by the installation box 8 until the scraper 9 contacts the packaging box, and then the fan 15 and the heating pipe 13 are turned on, and the heat fills the hot air box 12, and the heat is discharged through the hot air pipe 10 by the fan 15. At this time, the air valve 11 in the corresponding direction is opened, and the hot air in the hot air pipe 10 melts the colloid on the surface of the packaging box. When the scraper 9 moves, the corresponding glue can be scraped off. By heating and melting and coordinating with the movement of the scraper 9, the problem that the scraper 9 is inconvenient to clean the outer wall of the packaging box directly is solved; at the same time, the temperature in the hot air box 12 is sensed by the temperature sensor 14, and the temperature in the hot air box 12 is controlled by the temperature controller 16 to prevent the temperature from being too high and damaging the surface of the packaging box;

[0039] When the packaging box needs to be fixed, the packaging box moves on the conveyor belt. When the packaging box moves to the position of the limit box 19, the conveyor belt stops moving, and the cylinder 17 is turned on. The two cylinders 17 drive the limit box 19 through the output end to fix the packaging box. When the scraper 9 scrapes the glue, the glue flows into the limit box 19 through the permeation plate 24; flows to the bottom of the limit box 19 through the guide plate 30, and the suction pump 22 is turned on. The suction pump 22 pumps the glue in the limit box 19 to the recovery box 21 through the three-way pipe 23, and the glue is cleaned. Unified recycling; there is glue on the side wall of the scraper 9, which solidifies on the scraper 9 after a period of time, making the bottom of the scraper 9 uneven, making it inconvenient to scrape the outer wall of the packaging box.
