Description

Technical Field

[0001] This utility model relates to the field of IC tape and reel packaging technology, and in particular to an IC tape and reel heat sealing device. Background Technology

[0002] IC tape and reel packaging encapsulates a chip on a long tape made of plastic or other materials. Each package is arranged at a fixed spacing, and each package is connected to the tape via pins or pads, allowing it to connect to other components (such as circuit boards). The main purpose of tape and reel packaging is to facilitate mass production and assembly, improve production efficiency, better protect the chip, facilitate automated management, and reduce human error. IC tape and reel packaging includes two types: cold sealing and heat sealing. Generally speaking, heat sealing is more effective. The heat sealing process involves heating the tape carrier, melting it, and sealing it, thereby protecting the chip from external environmental influences and ensuring the chip's stability during transportation and storage.

[0003] Currently, fully automated heat-sealing packaging mechanisms heat a pressure knife using a heating element, then press the cover tape onto the carrier tape using the hot pressure knife to complete the heat sealing of IC products. However, traditional pressure knife mechanisms typically use pressure knives of fixed shape and size, making it difficult to adapt to products of different sizes and thicknesses. When product specifications change, the entire pressure knife module often needs to be replaced, which is not only time-consuming but also increases equipment maintenance costs and downtime, severely impacting production efficiency. Secondly, after prolonged use, the traditional pressure knife structure may experience decreased stability due to wear and loosening; the design of the fixing device is not reasonable enough to ensure the stability of the pressure knife structure during high-speed edge tape packaging. Thirdly, the traditional pressure knife mechanism has poor stability; due to instability during movement, the pressure knife may generate additional impact force when contacting the product, affecting product positioning accuracy and potentially causing damage. Furthermore, uneven heating of the traditional pressure knife leads to poor consistency in the indentation seal, failing to meet user requirements. In addition, existing pressure knife structures are complex, making operation, disassembly, and maintenance difficult.

[0004] Therefore, it is necessary to develop an IC tape heat sealing device that can quickly change the pressure knife, has more uniform heating, and has a simpler structure. Utility Model Content

[0005] The purpose of this invention is to provide an IC tape heat sealing device that allows for quick replacement of the pressure knife, more uniform heating, and a simpler structure.

[0034] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0035] Please see Figures 1 to 4This utility model provides an IC tape and reel heat sealing device 100, suitable for heat sealing IC chips between a carrier tape and a cover tape. The IC tape and reel heat sealing device 100 includes a power mechanism 10, a pressing mechanism 20, and a carrying mechanism 30 mounted on a frame (not shown). The power mechanism 10 includes a cylinder power assembly 12 and a motor cam assembly 11. The pressing mechanism 20 is connected to the output end of the cylinder power assembly 12. The cylinder power assembly 12 actuates to drive the pressing mechanism 20 to slide downwards along the frame via a slide rail assembly 210, causing the pressing mechanism 20 to abut against the motor cam assembly 11. The motor cam assembly 11 actuates to drive the pressing mechanism 20 to move up and down at a preset frequency, achieving up and down pressing. The preset frequency is a frequency that can heat-press the carrier tape and cover tape together during the heat pressing process without over-pressing. On the other hand, the pressing mechanism 20 includes a connecting assembly 21, an adjusting assembly 22, a heating assembly 23, and a pressing assembly 24. The connecting component 21 is mounted on the slide rail component 210, then connected to the cylinder power component 12, and slidably mounted on the frame via the slide rail component 210. The adjusting component 22, heating component 23, and pressure component 24 are all mounted on the connecting component 21. Specifically, the adjusting component 22 is mounted on the connecting component 21, the heating component 23 is connected to the adjusting component 22, and the pressure component 24 is connected to the heating component 23. The adjusting component 22 is used to adjust the connection between the heating component 23 and the pressure component 24, ensuring a balanced connection and uniform pressure. The heating component 23 is used to heat the pressure component 24. The carrying mechanism 30 is located below the pressure mechanism 20 and includes a feeding component 31 elastically mounted on the frame. The feeding component 31 is used to feed materials for heat-press packaging by the pressure component 24; that is, the IC chip is placed between the carrier tape and the cover tape, and then heat-pressed onto the feeding component 31 by the pressure component 24.

[0036] With the above technical solution, the IC tape and reel heat sealing device 100 of this utility model includes a power mechanism 10, a pressing mechanism 20, and a supporting mechanism 30 mounted on a frame. The power mechanism 10 includes a cylinder power assembly 12 and a motor cam assembly 11. The pressing mechanism 20 is connected to the output end of the cylinder power assembly 12. The cylinder power assembly 12 actuates to drive the pressing mechanism 20 to abut against the motor cam assembly 11. The motor cam assembly 11 actuates to drive the pressing mechanism 20 to move up and down at a preset frequency. The pressing mechanism 20 is easy to operate in terms of lifting and lowering. The up and down movement is used for heat pressing to avoid overheating and to achieve a good heat pressing effect. The pressing mechanism 20 includes a connecting assembly 21, an adjusting assembly 22, a heating assembly 23, and a pressing assembly 24. The connecting assembly 21 is connected to the cylinder power assembly 12 and is slidably mounted on the frame. The adjusting assembly 22, the heating assembly 23, and the pressing assembly 24 are all lifted and slid through the connecting assembly 21. The adjusting component 22 is used to adjust the position between the heating component 23 and the pressing component 24 to balance the pressure output of the pressing component, thereby improving the hot pressing effect. The heating component 23 is used to heat the pressing component 24, and its structural layout is reasonable. The supporting mechanism 30 is located below the pressing mechanism 20 and includes a feeding component 31 elastically mounted on the frame. The feeding component 31 is used to feed materials for hot pressing and encapsulation by the pressing component 24. The IC tape and reel heat sealing device 100 of this utility model has a reasonable structural layout and good hot pressing effect.

[0037] Please see Figures 3 to 7 In some optional embodiments, the pressure knife assembly 24 includes a heat-sealing pressure knife 241 and a mounting member 242. The heat-sealing pressure knife 241 is slidably connected to the heating assembly 23 and fixed to the heating assembly 23 by the mounting member 242. A sliding protrusion 2414 is provided on the heat-sealing pressure knife 241, and a groove 2312 that mates with the sliding protrusion 2414 is formed on the surface of the heating assembly 23 near the pressure knife assembly 24. The heat-sealing pressure knife 241 can be slidably disposed within the groove 2312 via the sliding protrusion 2414, and can slide along the groove 2312 via the sliding protrusion 2414. On the other hand, the heating assembly 23 includes a heat-conducting block 231 and a heating rod 232. A mounting hole 2311 for mounting the heating rod 232 is formed in the heat-conducting block 231, and the heating rod 232 is mounted in the mounting hole 2311 and conducts heat outward through the heat-conducting block 231. A groove 2312 is formed on a heat-conducting block 231, which is made of brass. The brass heat-conducting block 231 can improve the heat uniformity of the heat-sealing die 241. The heat-sealing die 241 has even pressure and uniform heating, which makes the heat-sealing of IC chips between the carrier tape and the cover tape better, with consistent indentations, thus improving the packaging quality.

[0038] Please see Figure 6In some optional embodiments, the heat-sealing press 241 includes a pressing part 2411, which protrudes from the heat-sealing press 241 in a direction away from the heating assembly 23. In this embodiment, there are two pressing parts 2411, which are arranged along the length of the heat-sealing press 241, forming a pressing space 2412 between the two pressing parts 2411. When the cover tape and carrier tape are heat-pressed, the IC chip is located in the pressing space 2412 between the two pressing parts 2411, which can avoid damaging the IC chip.

[0039] Please see Figures 3 to 7 In some optional embodiments, the heat-sealing press 241 is provided with a first positioning part 2413 that cooperates with the mounting member 242, and the mounting member 242 is provided with a second positioning part 2421 that cooperates with the first positioning part 2413. A limiting part 2415 is provided on one side of the first positioning part 2413. The heat-sealing press 241 slides along the slide groove 2312 via the sliding protrusion 2414, and the first positioning part 2413 slides along the second positioning part 2421 until the second positioning part 2421 abuts against the limiting part 2415, locking the mounting member 242 so that the second positioning part 2421 locks the first positioning part 2413. Releasing the mounting member 242 allows the heat-sealing press 241 to slide away from the heating assembly 23. Specifically, the first positioning part 2413 has a downwardly sloping surface from the outside in. The second positioning part 2421 protrudes from the body and has a sloping surface that cooperates with the first positioning part 2413. The heat-sealing pressure knife 241 is fixed to the heat-conducting block 231 by engaging the first positioning part 2413 with the second positioning part 2421. The heat-conducting block 231 has mounting grooves 2313 on both sides for accommodating the mounting component 242. The mounting component 242 is installed in the mounting groove 2313 and then locked onto the heat-conducting block 231 through the locking hole 2422, thus locking the heat-sealing pressure knife 241. When the heat-sealing pressure knife 241 needs to be replaced, the mounting component 242 is released from the heat-conducting block 231, allowing the heat-sealing pressure knife 241 to slide away from the heat-conducting block 231 via the sliding protrusion 2414 along the sliding groove 2312, achieving quick replacement of the heat-sealing pressure knife 241. This allows for quick replacement of the heat-sealing pressure knife 241 according to different products without replacing the entire pressure knife module, offering convenient operation, high efficiency, and stronger compatibility.

[0040] Please see Figure 4In some optional embodiments, the adjustment component 22 includes a left-right adjustment structure 222 and a right-right adjustment structure 221. These structures are used to adjust the connection between the heating component 23 and the pressure-cutting component 24 to balance the output pressure of the pressure-cutting component 24. The left-right adjustment structure 222 adjusts the connection between the heating component 23 and the pressure-cutting component 24 in the left-right direction to balance the pressure in that direction. The right-right adjustment structure 221 adjusts the connection between the heating component 23 and the pressure-cutting component 24 in the right-right direction to balance the pressure in that direction.

[0041] Please see Figure 2 In some optional embodiments, the motor cam assembly 11 includes a drive motor 111 and a cam structure 112. The cam structure 112 is mounted on the output end of the drive motor 111. The drive motor 111 starts to drive the cam structure 112 to rotate, thereby driving the connecting assembly 21 to slide up and down along the frame. The rotation of the cam structure 112 automatically drives the entire pressing mechanism 20 to slide up and down according to the frequency of the rotation of the cam structure 112, thereby realizing the up and down swing of the heat-sealing pressing knife 241, and thus completing the heat sealing pressing of the cover tape and the carrier tape. The connecting assembly 21 can be made of acrylic material to balance the temperature and prevent accidental contact by the operator. On the other hand, the air inlet end of the cylinder power assembly 12 is equipped with a pressure regulating valve, which can adjust the cylinder pressure as needed. The output end of the cylinder power assembly 12 is connected to an Airtac digital display pressure gauge to monitor the cylinder pressing pressure value in real time. The pressure value can be set, and an alarm will be triggered when the pressure exceeds or falls below the set value, enhancing stability and reliability.

[0042] Please see Figure 1 and Figure 8 In some optional embodiments, the feeding assembly 31 includes a feeding trough 311 for feeding, a pressure plate 312 is provided on the feeding trough 311, and a through groove 313 is formed on the pressure plate 312. The heat-sealing pressure knife 241 passes through the through groove 313 to heat-seal the workpiece in the feeding trough 311. On the other hand, an elastic buffer assembly 32 is connected to the bottom of the feeding assembly 31, which allows the pressure knife assembly 24 to elastically press the feeding assembly 31. The feeding trough 311 serves to support the carrier belt and prevent the carrier belt from shifting position. The elastic buffer assembly 32 at the lower end is equipped with a spring, which can quickly reduce the vibration caused by the pressure knife during operation and ensure the sealing quality of the cover tape and the carrier tape.

[0043] like Figures 1 to 8As shown, the IC tape and reel heat sealing device 100 of this utility model includes a power mechanism 10, a pressing mechanism 20, and a supporting mechanism 30 mounted on a frame. The power mechanism 10 includes a cylinder power assembly 12 and a motor cam assembly 11. The pressing mechanism 20 is connected to the output end of the cylinder power assembly 12. The cylinder power assembly 12 actuates to drive the pressing mechanism 20 against the motor cam assembly 11. The motor cam assembly 11 actuates to drive the pressing mechanism 20 to move up and down at a preset frequency, which can avoid excessive heat pressing and achieve a good heat pressing effect. The pressing mechanism 20 includes a connecting assembly 21, an adjusting assembly 22, a heating assembly 23, and a pressing assembly 24. The connecting assembly 21 is connected to the cylinder power assembly 12 and slidably mounted on the frame. The adjusting assembly 22, the heating assembly 23, and the pressing assembly 24 all slide and rise through the connecting assembly 21. The adjusting assembly 22 is used to adjust the position between the heating assembly 23 and the pressing assembly 24 to balance the pressure output of the pressing tool, thereby improving the heat pressing effect. The heating component 23 is used to heat the pressing knife component 24, and uses a brass heat-conducting block 231, which has good heat conduction and ensures more uniform heating of the heat-sealing pressing knife 241. The supporting mechanism 30 is located below the pressing knife mechanism 20 and includes a feeding component 31 elastically mounted on the frame. The feeding component 31 is used to feed materials for heat-sealing by the pressing knife component 24. The IC tape heat-sealing device 100 of this utility model has a reasonable structural arrangement, which can enhance the pressure uniformity of the heat-sealing pressing knife 241, improve the heating uniformity of the heat-sealing pressing knife 241, and has strong compatibility, allowing for quick replacement of various heat-sealing pressing knives 241 as needed, resulting in higher efficiency and better heat-sealing pressing effect.
