Description

Technical Field

[0001] This invention relates to the field of die bonders, and more particularly to a die bonder. Background Technology

[0002] As electronic components become increasingly miniaturized and highly integrated, the die bonding process, as a key step in semiconductor packaging, directly impacts the yield of the final product. Currently, the industry generally uses automated die bonding equipment to replace manual operation, achieving high-precision placement through robotic arms and vision positioning systems. However, the complexity and cost of the equipment remain high. In recent years, the LED industry has placed higher demands on the production capacity of die bonding equipment, prompting equipment manufacturers to continuously optimize and innovate in areas such as motion control and dispensing processes. However, there is still room for improvement in the ease of maintenance and production efficiency of current die bonding machines.

[0003] Traditional die bonders suffer from poor speed and precision during the production process. Increasing the die bonding speed may lead to a decrease in positioning accuracy, especially for products with small pin pitch and precise chip size. A compromise must be made between the two, making it difficult to achieve the best performance at the same time. Furthermore, the adhesive dispensing and placement processes cannot be performed in parallel, which significantly affects production efficiency. If the adhesive dispensing process is delayed until the placement process is completed before proceeding to the next step, the adhesive material may change due to prolonged exposure to air, affecting the final bonding effect. In addition, existing equipment needs to move back and forth between the adhesive dispensing position and the placement position multiple times. Frequent mechanical movement may cause slight vibrations or displacement deviations in components such as the worktable and nozzle. Over time, this will reduce positioning accuracy and increase the probability of chip misalignment and misplacement.

[0004] Therefore, a new approach is needed to solve this problem. Summary of the Invention

[0005] 1. Technical problems to be solved The purpose of this application is to provide a die bonder to solve the problem that existing devices cannot achieve parallel processing of adhesive dispensing and mounting processes through the collaborative operation of two robotic arms and the time overlap design.

[0006] The die bonding machine provided in this application adopts the following technical solution: it includes a fixed base, a frame is fixedly connected to the upper surface of the fixed base, a connecting frame is fixedly connected to the outer surface of the frame, a glue holder is fixedly connected to the outer surface of the connecting frame, a glue tray is fixedly connected to the outer surface of the glue holder, a mounting frame is slidably connected to the inner wall of the frame, a dispensing machine is fixedly connected to the outer surface of the mounting frame, a dispensing arm is rotatably connected to the bottom surface of the dispensing machine, a dispensing head is fixedly connected to the bottom surface of the dispensing arm, a fixed frame is fixedly connected to the outer surface of the frame, a second motor is fixedly mounted on the upper surface of the fixed frame, a swing arm is fixedly connected to the output end of the second motor, and the outer surface of the swing arm is rotatably connected to the fixed frame.

[0007] By adopting the above technical solution, a fixed base serves as the supporting foundation for the entire equipment, providing a stable installation platform for all components above and ensuring the overall stability of the equipment during operation. The frame, fixed on the fixed base, is the skeleton of the equipment, used to connect and support other key components. The connecting frame is fixed on the outer surface of the frame, and the glue tray is connected to the frame through the connecting frame, serving to fix and support the glue tray. The glue tray is installed on the glue tray to store the raw materials required for the dispensing process. The dispensing machine is fixed on the mounting frame, and the dispensing arm is rotatably connected to the bottom surface of the dispensing machine. The angle of the dispensing arm can be adjusted through the dispensing machine's control, facilitating direct contact between the dispensing head at the end of the dispensing arm and the glue to complete the dispensing action. The dispensing arm is connected through a magnetic quick-release interface. The three components work together to achieve precise glue dispensing and application. By starting the second motor, it drives the swing arm to swing around the central axis of the second motor's output end. This allows the chip to be applied with glue through the dispensing component and the chip to be transported and placed by the swing arm component. Through the collaborative operation of the two robotic arms and the time overlap design, the glue dispensing and placement processes can be processed in parallel.

[0008] Preferably, a support is provided below the fixed frame, a detection platform is fixedly installed on the upper surface of the support, a detector is fixedly installed on the upper surface of the fixed frame, a detection head is fixedly connected to the output end of the detector, a second sliding groove is provided on the outer surface of the fixed base, a first sliding groove is provided on the side of the frame near the second sliding groove, a first connecting plate is slidably connected to the inner wall of the first sliding groove, and a second connecting plate is slidably connected to the inner wall of the second sliding groove.

The inspection table is fixed on the upper surface of the bracket and serves as a temporary placement and inspection platform for chips or substrates. It is used to perform positioning verification and quality inspection of the workpiece during the die bonding process. The detector is fixed on the upper surface of the fixed frame, corresponding vertically to the inspection table. The detection head connected to its output end should face the inspection table.

The first slide groove is opened on the side of the frame near the second slide groove, and the first connecting plate is slidably connected to its inner wall. This structure allows the first connecting plate to move along the direction of the first slide groove. The second slide groove is similar to the first slide groove.

Its output end is directly connected to the threaded rod. The rotation direction of the threaded rod is controlled by the forward and reverse rotation of the first motor. When the first motor drives the threaded rod to rotate, the mounting frame can be moved axially along the threaded rod by utilizing the thread transmission principle, so as to realize the precise adjustment of the dispensing machine position. The connecting rod provides guidance and support for the movement of the mounting frame, preventing the mounting frame from rotating or deviating under the drive of the threaded rod, and ensuring the stability and linear accuracy of the dispensing machine when it moves.

[0013] By adopting the above technical solution, the third motor provides driving force as a power source, and its output end is directly connected to the first screw. The rotation direction of the first screw is controlled by the forward and reverse rotation of the third motor. When the third motor drives the first screw to rotate, the first connecting plate moves synchronously along the first slide groove and the second connecting plate moves synchronously along the second slide groove through the thread transmission. Through the mechanical transmission of the first screw driven by the third motor, the movement distance of the first screw can be precisely controlled, further expanding the adjustable range of the equipment and adapting to more specifications of workpieces or process requirements.

[0017] By adopting the above technical solution, the track plate is fixedly connected to the inner wall of the frame, serving as an independent high-precision track carrier. Its material is precision engineering plastic, ensuring the stability and low coefficient of friction during the sliding process, providing a foundation for the precise movement of subsequent components. The fixed plate is slidably connected to the inner wall of the third slide groove, allowing it to move stably along the third slide groove. This provides higher sliding accuracy and stability, reduces wear or shaking caused by long-term use, and ensures that the components on the fixed plate maintain millimeter-level or even micrometer-level positional accuracy during movement.

[0018] Preferably, the output end of the fourth motor is fixedly connected to a second screw, and the outer surface of the second screw is rotatably connected to both the third connecting plate and the fixing plate.

[0019] By adopting the above technical solution, when the fourth motor drives the second screw to rotate, it drives the fixed plate to slide along the third slide groove through the threaded transmission.

[0020] Preferably, a worktable is slidably connected to the inner wall of the frame, and two threaded grooves are formed inside the worktable. The inner wall of each threaded groove is threadedly connected to the corresponding first screw and second screw, and a work plate is fixedly installed on the upper surface of the worktable.

Its sliding characteristics enable it to achieve overall position adjustment within the frame, providing a basis for multi-station switching of the workpiece. Two threaded grooves are opened inside the worktable, which are threadedly connected to the first screw and the second screw respectively. Through the cooperation of the third motor and the fourth motor, the two-dimensional plane movement of the worktable can be achieved to meet the processing requirements of the workpiece in different positions. The work plate is fixed on the upper surface of the worktable, and its surface is provided with positioning grooves, vacuum adsorption holes and fixture mounting positions to stably fix the workpiece and ensure that the workpiece does not shift during the die bonding process.
