Description

Technical Field

[0001] This utility model relates to the field of chip packaging technology, specifically a rotary coating device for chip packaging equipment. Background Technology

[0002] In the field of chip packaging, traditional adhesive application methods primarily rely on simple mechanical devices. Specifically, these methods typically involve using tools such as brushes, spray guns, or stationary adhesive applicators. However, these traditional methods have several significant shortcomings in practical applications: First, from the perspective of uniformity and precision, traditional methods struggle to accurately control the amount and thickness of adhesive applied, easily leading to uneven application. This unevenness not only affects the appearance quality of the chip package but can also negatively impact its heat dissipation and electrical performance, thus reducing the overall package quality. Second, due to their design limitations, stationary adhesive applicators typically only perform unidirectional application, failing to achieve omnidirectional coating of the chip package surface. This limitation not only affects the uniformity and consistency of the coating effect but can also lead to insufficient or excessive coating in certain areas, consequently affecting the overall performance and reliability of the chip package.

[0003] In summary, traditional coating methods have significant shortcomings in terms of uniformity, precision, efficiency, and coating range. There is an urgent need to introduce a rotary coating device for chip packaging equipment to improve the overall quality and production efficiency of chip packaging. Utility Model Content

The storage bin 5 is made of corrosion-resistant, high-strength material to ensure it will not deform or leak during long-term use.

[0067] A pump body 4 is installed inside the storage silo 5. The function of the pump body 4 is to deliver the adhesive material in the storage silo 5 to the dispensing position under pressure. The output end of the pump body 4 is connected to a dispensing pipe 3, which is made of a flexible material that is resistant to high pressure and corrosion to ensure that it does not break or become blocked during the conveying process. The other end of the dispensing pipe 3 extends into the dispensing channel 1401 of the supporting column 14.

[0068] The support column 14 serves as the support structure for the entire device, and it has an internal injection channel 1401. The design of the injection channel 1401 ensures that the adhesive can flow smoothly into the inlet 1203 of the pipe body 1201.

[0071] Operating steps

[0072] Preparation: Load the material to be injected into storage bin 5, ensuring that there is enough material in storage bin 5.

[0073] Start the pump: Start the pump 4 through the control system. The pump 4 will transport the adhesive in the storage bin 5 to the injection channel 1401 of the support column 14 through the adhesive delivery pipe 3.

[0074] Start the servo motor: The control system starts the servo motor 13, which drives the spiral feed slurry 1202 to rotate, and evenly feeds the rubber material in the injection channel 1401 into the feed port 1203 of the tube body 1201.

[0075] Injection process: Under the coordinated action of servo motor 13 and pump body 4, the adhesive is continuously and evenly injected into tube body 1201 to complete the injection process.

[0076] A scraper mechanism 11 is provided on one side of the support column 14. The scraper mechanism 11 includes a crossbar 1103 connected to the support column 14. A scraper 1102 is provided at the bottom of one end of the crossbar 1103 through the mounting groove 1101.

[0077] The crossbar 1103 is connected to the support column 14 by bolts or other fixing methods. The crossbar 1103 is made of rigid material to ensure that it will not deform during the adhesive application process. One end of the crossbar 1103 extends above the support platform 7, and the other end is fixed to the support column 14.

[0078] Mounting slot 1101 is located at the bottom of one end of crossbar 1103 and is used to mount scraper 1102. The design of mounting slot 1101 should ensure that scraper 1102 can be firmly fixed to crossbar 1103 and will not loosen during the application of adhesive. The shape of mounting slot 1101 can be adjusted according to the size of scraper 1102 to achieve the best installation effect.

[0079] The scraper 1102 is made of high-hardness material, offering excellent wear resistance and effective adhesive scraping. The cutting edge of the scraper 1102 undergoes special treatment to ensure smooth removal of excess adhesive during the scraping process. The installation angle of the scraper 1102 can be adjusted to accommodate adhesives of varying thicknesses.

[0080] The support platform 7 is used to support the workpiece to be coated with adhesive. Its surface is specially treated to ensure that the adhesive can be evenly coated on the workpiece. The support platform 7 is connected to the drive device through a transmission mechanism and can rotate below the scraper mechanism 11.

[0081] When the support platform 7 rotates to a position below the scraper mechanism 11, the scraper 1102 scrapes off the excess adhesive on the support platform 7.

[0082] Preparation: Place the workpiece to be coated with adhesive on the support platform 7, and adjust the height of the support platform 7 to align it with the cutting edge of the scraper 1102.

[0083] Adhesive scraping process: When the support platform 7 rotates to a position below the scraper mechanism 11, the scraper 1102 scrapes off excess adhesive. The contact between the cutting edge of the scraper 1102 and the surface of the support platform 7 should be uniform to ensure effective adhesive scraping.

[0084] In this embodiment, the chip is placed on top of the support platform 7. The rotary motor 6 drives the drive gear 601 to rotate, which in turn drives the rotary table 2 to rotate via the active rack 204 and the inner ring 205. This causes the support platform 7 to rotate around the dispensing assembly 12. When the driven gear 702 at the top of the bottom rotating shaft 701 of the support platform 7 contacts the speed regulating gear set 9, the transmission rack 203 inside the inner ring 202 drives the speed regulating gear set 9 to rotate. The speed regulating gear set 9 then drives the driven gear 702 to rotate. The drive platform 7 rotates to achieve chip-finding and adhesive application. The pump body 4 starts and delivers the adhesive through the glue delivery pipe 3 to the inside of the pipe body 1201 via the injection channel 1401. The servo motor 13 starts and drives the spiral feed slurry 1202 to rotate, evenly delivering the adhesive to the discharge port 1204. The adhesive is then applied to the chip on the top of the platform 7 through the coating head 1205. When the platform 7 rotates to the bottom of the scraper mechanism 11, the scraper 1102 scrapes off the excess adhesive to ensure uniform adhesive application.
