Description

Technical Field

[0001] This utility model relates to the field of surface mount material changing technology, and in particular to a rapid material changing mechanism for a surface mount packaging integrated machine. Background Technology

[0002] A die bonder, also known as a chip mounter, is the most critical and essential piece of equipment in the die attach process of chip packaging and testing. Its main function is to pick up the chip from the diced wafer and place it on the corresponding die flag on the substrate, then use epoxy to bond the chip to the substrate. Die bonders can place components at high speed and with high precision, performing key steps such as positioning, alignment, flip-chip bonding, and continuous placement. Regardless of how packaging methods evolve, the packaging process is inseparable from the die attach process. Currently, die attach packaging machines still require manual reloading, which involves checking the reel, cutting the die, and connecting it with tape. This reloading operation is complex, time-consuming, and reduces worker efficiency.

[0003] Therefore, it is necessary to design a quick material changing mechanism for a surface mount packaging machine to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0020] Example: A quick material change mechanism for a surface mount packaging machine, such as... Figures 1-5 As shown, the assembly includes a mounting frame 1, a spiral rod 2, a clamping block 3, a knob 4, a feeding frame 5, a material changing platform 7, a sliding rod 8, and a tool holder 9. The mounting frame 1 has two slots at its bottom. The spiral rod 2 is threadedly connected to the right side of the mounting frame 1. The clamping block 3 is fixedly connected to the left side of the spiral rod 2. The knob 4 is fixedly connected to the right side of the spiral rod 2. The feeding frame 5 is bolted to the upper part of the mounting frame 1. The winding wheel 6 is bolted to the front right side of the feeding frame 5. The material changing platform 7 is fixedly connected to the middle of the feeding frame 5. The sliding rod 8 is slidably connected to the material changing platform 7. The tool holder 9 is fixedly connected to the top of the sliding rod 8. A spring 10 is fixedly connected between the tool holder 9 and the material changing platform 7. The spring 10 is sleeved on the sliding rod 8. The material changing platform 7 has a slot 12 located directly below the tool holder 9.

[0021] like Figure 3 As shown, it also includes a push block 11, which is fixedly connected to the rear side of the tool holder 9.

[0022] like Figure 1 and Figure 4 As shown, it also includes a feeding frame 13, a motor 14 and a feeding ring 15. The feeding frame 13 is bolted to the upper front side of the feeding frame 5. The motor 14 is installed on the front side of the feeding frame 13. The output shaft of the motor 14 is fixedly connected to the feeding ring 15. The feeding ring 15 is slidably connected to the feeding frame 13.

[0023] like Figure 4 As shown, it also includes a scanner 16, which is provided on the upper part of the feeding ring 15.

[0024] like Figure 1 and Figure 5 As shown, it also includes a material return cover 17 and a handle 18. The material return cover 17 is threadedly connected to the front side of the material discharge frame 5, and the handle 18 is fixedly connected to the front side of the material return cover 17.

[0025] like Figure 5 As shown, it also includes a pull rod 19 and a handle 20. The bottom of the feeding frame 5 is slidably connected to the pull rod 19, and the front side of the pull rod 19 is fixedly connected to the handle 20.

[0026] When this device is needed to assist in changing materials for the SMT packaging machine, first fix the device near the machine using the two slots at the bottom of the mounting bracket 1. Then, rotate the two knobs 4 counterclockwise to move the two clamping blocks 3 to the left, further securing the device. Place the tray on the feeding ring 15 and start the scanner 16 to scan the tray. If the tray is different from the one currently in use, prompt the operator to replace it. Once the replacement tray is different from the one currently in use, start the motor 14 to rotate the feeding ring 15 90 degrees clockwise, thus dropping the tray into the feeding frame 5. Then, manually move the tray backward to the left side of the slot 12. The operator can feed the material again using the above method. When the material in the tray of the SMT packaging machine is almost used up, wind the remaining material onto the winding reel 6, pull the end of the material onto the slot 12, and then pull out the material from the feeding frame 5. Place the material on slot 12, align the two ends, and then press down on push block 11 to drive cutter 9 to cut the material on slot 12. At the same time, spring 10 is compressed. Then release push block 11, and cutter 9 is reset by extending spring 10. Take out the cut waste material, and then use special tape to connect the two cut ends. The chip packaging machine can continue to operate. When the material in the tray is used up, continue to use the remaining tray on the feeding frame 5 through the above operation. When the material in the feeding frame 5 is used up, place a box at the bottom of the unloading cover 17. Turn the unloading cover 17 counterclockwise by handle 18 until it is detached from the feeding frame 5. Then pull handle 20 forward to drive pull rod 19 to push the tray on the feeding frame 5 forward until the tray on the feeding frame 5 falls into the box. Then pull handle 20 backward to drive pull rod 19 to reset. Then turn unloading cover 17 clockwise by handle 18 until it is reset.
