Description

Technical Field

[0001] This utility model relates to the field of die bonder technology, specifically to a wire feeding structure suitable for die bonders. Background Technology

[0002] Die bonding machines are mainly used for lead frame plates of various gold wire ultrasonic welding equipment, as well as various nozzles, ejector pins, dispensing heads, ceramic nozzles, through needles, motors, carbon brushes, encoders, drive belts, various spare parts of automation equipment, instruments, meters, etc.

[0003] Existing die bonders rely on traditional clamps to "clamp" and fix the wire before processing. This is prone to radial displacement due to vibration and wear, which leads to a decrease in die bond yield. In addition, each wire needs to be disassembled and reassembled, and changing a single wire takes a lot of time. To address these issues, we propose a wire feeding structure suitable for die bonders. Utility Model Content

[0004] The purpose of this invention is to provide a wire feeding structure suitable for die bonders, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire feeding structure suitable for a die bonder, comprising a worktable, a die bonder body, and a fixed base, wherein the die bonder body is mounted on the top of the worktable, the fixed base is mounted on the right side of the worktable, and a sliding device is provided on the inner side of the fixed base;

[0006] The sliding device includes a first fixing groove, a connecting groove, and a storage groove. The first fixing groove is located on the left side inside the fixed base, and the connecting groove is located on the right side of the first fixing groove. Multiple storage grooves are located on the right side of the connecting groove. Telescopic springs are installed on both sides inside the storage grooves. The top of the telescopic springs on both sides is installed on the bottom of the plate. A base is located on the top of the plate. The base has slots on both sides. The slots have locking blocks inside. The locking blocks are installed on both sides of the bottom of the fixed plate. A material discharge groove is located at the middle of the bottom of the fixed plate and the middle of the top of the base. A protective pad is installed on the inner wall of the material discharge groove. Locking plates are installed on both sides of the fixed plate. The material discharge groove is located inside the second fixing groove, which is located inside the fixed base.

[0007] Preferably, the top of the workbench is on the same horizontal line as the bottom of the first fixing groove, and multiple partitions are installed above both the first fixing groove and the connecting groove.

[0008] Preferably, the two partitions are correspondingly arranged between each other and between the plates, and the fixing seats are integrated with the first fixing groove, the connecting groove and the storage groove.

[0009] Preferably, the connecting groove is sloped, and the right side of the connecting groove is on the same horizontal line as the top of the plate.

[0010] Preferably, the plate and the storage tank are slidably connected, and the base and the storage tank are correspondingly arranged.

[0011] Preferably, the base and the slot are integrated, and the slot and the block are engaged.

[0012] Preferably, the card block and the fixing plate are fixedly connected, and the fixing plate and the second fixing groove are fixedly connected.

[0013] Preferably, the adjacent card plates are correspondingly arranged, and the material feeding groove is circular.

[0014] Preferably, the material discharge trough and the protective pad are fitted together tightly.

[0015] Preferably, the middle positions of the feeding trough, the fixing plate, and the base are on the same horizontal line.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] By setting up a first fixing slot, a connecting slot, and a storage slot, multiple fixing plates are stacked by the interlocking of the side plates. The interlocking structure eliminates the need for tool disassembly and assembly, reducing the complexity of manual operation. The material feeding slot on the top of the fixing plate is used to place the line body. The base is fitted with the bottom block of the fixing plate by the side slot, limiting the line body in the feeding slot. The protective pad elastically wraps the line body to eliminate gaps and prevent movement, and reduce line body wear. The clamping plate neatly stacks the assembled base, fixing plate, and line body components in the storage slot inside the fixing base for later use. It can also be assembled in batches, improving the efficiency of line changeover.

[0018] During use, the user presses the fixing plate of the target component, which separates from the fixing plate of the adjacent component. The entire component falls to the bottom of the second fixing slot, achieving the independence of a single line. The expansion spring at the bottom of the storage slot rebounds, lifting the plate upwards until the upper edge of the plate is flush with the right side of the connecting slot. Then, the fixing plate is pushed, causing the internal partition, connecting slot, and first fixing slot channel of the component fixing seat to slide, accurately and smoothly delivering the welding head of the line to the welding position of the material above the worktable, improving the yield of die bonding. The die bonding machine body suspended above the worktable is then started to complete the die bonding connection between the line and the material. Attached Figure Description
