[0024] like Figure 1 and Figure 2 As shown, the chip dispensing device with a flipping function provided in this embodiment includes an operating table 1, a dispenser 5, a chip flipper and a main controller 2; the dispenser 5 and the chip flipper are arranged on the table top of the operating table 1, and the dispenser 5 is arranged on the mounting frame 3 of the operating table 1 and faces the chip flipper; the chip flipper includes a rack 6 and a flipping mechanism 7, the rack 6 is arranged on the table top through the flipping mechanism 7, the chip to be dispensed is fixed on the rack 6, the flipping mechanism 7 is movably connected to the rack 6 through a rotating shaft, and the two ends of the rack 6 are driven by the rotating shaft to make the rack 6 rotate around the rotating shaft under force; the main controller 2 is connected to the dispenser 5 and the chip flipper through a control signal to control the dispenser 5 to align with the corresponding position of the chip to be dispensed for dispensing glue.

[0025] In actual use scenarios, the controller can detect abnormal conditions in the operation of the equipment and alert the operator through alarm signal output. The controller can monitor the status of the safety door to ensure that the equipment automatically stops running when the safety door is opened. According to the requirements of the dispensing process, the controller can adjust the pulse frequency to achieve different movement speeds. By setting the electronic gear ratio, the ratio between the motor rotation and the actual movement axis can be adjusted to adapt to different working scenarios. The driver usually has an overheat protection function. When the temperature exceeds the set value, the enable signal is automatically turned off to protect the driver and motor. The driver can set the current limit to protect the motor from damage by excessive current. In order to improve the anti-interference ability, the driver usually uses optical coupling or magnetic coupling isolation technology to ensure the isolation of the control signal from the internal circuit of the driver. For servo motors, the driver receives position feedback from the motor's built-in encoder to achieve closed-loop control and ensure the accuracy of the dispensing position. The chip dispensing device design takes into account multiple key factors, including precise motion control, reliable safety monitoring and flexible communication interfaces. These features all help to improve production efficiency and quality while reducing operating and maintenance costs. In the further development process, it is possible to consider how to optimize the user interface, fault diagnosis system and adaptive control algorithm of the device to further enhance the intelligence and ease of use of the device. It is crucial to ensure that the controller is stably powered. The 24V DC power supply is a commonly used power supply standard in industrial control systems. It provides stable energy for the controller and its related circuits. The combination of USB and Ethernet ports provides a flexible communication method for the device. The USB port is convenient for on-site programming and debugging, while the Ethernet port is suitable for network integration and data exchange in the production environment. The purpose of these ports is to receive external signals such as emergency stop buttons, start buttons, etc., which can immediately affect the operating status of the device. The output of these ports directly controls the motor driver, thereby achieving precise control of the motor. The use of differential signals can effectively reduce noise interference and improve the reliability of signal transmission. By changing the level state, the controller can instruct the motor driver to change the direction of rotation of the motor, which is very important for the precise positioning of the dispensing machine. The power access of the motor driver needs to be selected according to the specifications of the motor to ensure that the motor can get enough power. The role of the enable signal is to activate or disable the motor driver when needed, which not only helps to save energy, but also can quickly stop the motor in an emergency and improve operational safety. These signals are the core control signals of the motor driver. The stepper motor driver controls the step of the stepper motor through a pulse signal, while the servo motor driver combines encoder feedback to achieve closed-loop control, providing higher accuracy and stability. The controller and driver should have a fault detection function, which can promptly alarm and take measures when a fault occurs. Since dust, oil, etc. may exist in the industrial environment, the protection level of the controller and driver should meet the requirements of the on-site environment.The controller needs to have strong software support, including programming environment, diagnostic tools and user interface, for easy operation and maintenance. The above chip dispensing device will be able to achieve efficient and precise dispensing operations and adapt to various industrial production environments.

[0026] In summary, through the motion control of four axes (X, Y, Z axis and rotation axis), the device can achieve high-precision dispensing position positioning. The independent control of each axis ensures that the dispensing head can accurately reach the predetermined coordinate point, thereby ensuring the consistency and accuracy of dispensing. The integration of the chip flipper allows the chip to be flipped during the dispensing process, which is particularly important for application scenarios where dispensing is required on multiple sides of the chip. The flipping function improves the flexibility and versatility of dispensing. The automated design of the device greatly reduces manual operation and improves production efficiency. Through the preset program of the main controller 2, the dispensing process can be completed automatically, reducing human errors and labor costs. The main controller 2 supports USB and Ethernet communication, making program downloading, parameter setting and remote monitoring simple and fast. Users can flexibly adjust and optimize the dispensing program according to different dispensing requirements. The enable signal and fault detection function of the driver improve the safety of operation. In an emergency, the enable signal can quickly disable the motor to prevent accidental injury. At the same time, fault detection can detect problems in time and avoid equipment damage. The use of differential signals for motion control improves the signal's anti-interference ability and ensures stable dispensing performance even in complex industrial environments. Through intelligent control of enabling signals, the device can automatically disable the motor when it is not needed, effectively saving energy and reducing operating costs. The user-friendly operating interface and diagnostic tools make the operation and maintenance of the equipment easier. The software support function can help operators get started quickly and reduce training time. The core technical effects of the device are reflected in its high precision, automation, flexibility, safety and ease of use, which make it very suitable for precision dispensing operations in industries such as semiconductors and electronic assembly, helping to improve product quality and production efficiency.

[0027] Furthermore, a plurality of chip flippers are arranged on the table top of the operating table 1 .

[0028] Furthermore, the storage rack 6 is configured as a two-sided frame structure.

[0029] Furthermore, the storage rack 6 is a rectangular frame structure.

[0030] Furthermore, a first sliding track 4 is provided on the mounting frame 3 , and the glue dispenser 5 is movably connected to the first sliding track 4 , and the glue dispenser 5 slides horizontally along the first sliding track 4 .

[0031] Furthermore, a second sliding track is arranged on the upper surface of the operating table 1, and the chip flipper is movably connected to the second sliding track. The chip flipper slides horizontally along the second sliding track and the running directions of the first sliding track 4 and the second sliding track are perpendicular.

[0032] Specifically, the two-sided frame structure increases the stability and rigidity of the rack 6, ensuring the positioning accuracy of the chip during the dispensing process. In addition, this structure is also conducive to the rapid loading and unloading of the chip, improving the operating efficiency. The dispenser 5 is movably connected to the mounting frame 3 through the first sliding track 4, so that the dispenser 5 can move in the horizontal direction (usually the X axis), so as to cover different dispensing positions on the operating table 1. The design of the sliding track ensures the smooth movement of the dispenser 5, reduces vibration, and improves the dispensing quality. The chip flipper is movably arranged on the operating table 1 through the second sliding track, allowing the flipper to move in the vertical direction (usually the Y axis). Such a design allows the chip to be dispensed at different heights, increasing the flexibility of dispensing. At the same time, since the running directions of the first sliding track 4 and the second sliding track are perpendicular, the two-dimensional movement of the dispenser 5 on the plane can be realized, further improving the coverage and accuracy of dispensing. Through the sliding tracks in two vertical directions, the device can realize accurate dispensing positioning in the XY plane, and combined with the flipping function of the chip flipper, dispensing operations in three-dimensional space can be realized. The design of the device allows for quick chip replacement and adjustment of dispensing positions, reducing downtime during production and improving production efficiency. Through the design of the sliding track, the device achieves multifunctional operation in a limited space and optimizes the space utilization of the work area. Operators can easily achieve a variety of dispensing modes by adjusting the position of the dispenser 5 and the chip flipper according to different dispensing needs. Improved equipment durability: The stable frame structure and precise sliding track design enhance the overall durability of the equipment and reduce maintenance costs. Overall, these design features give the chip dispensing device significant advantages in accuracy, efficiency, flexibility and durability, making it very suitable for use in the electronics manufacturing industry that requires high precision.

[0033] Furthermore, a plurality of chip flippers are arranged on the table top of the operating table 1 , and each chip flipper is arranged according to the moving direction of the first sliding track 4 .

[0034] Furthermore, the main controller 2 includes a power control end and a direction signal control end; the main controller 2 is connected to the dispenser 5 and the chip flipper through the power control end, and the power control end generates an electrical signal according to the flip angle control signal generated by the direction signal control end to control the running speed of the dispenser 5 and the flip speed of the chip flipper.

[0035] Furthermore, the main controller 2 also includes a communication terminal, which is connected to the direction signal control terminal, and generates an emergency control signal to control the signal generation process of the direction signal control terminal.

[0036] Furthermore, the main controller 2 also includes a digital quantity input terminal, which is connected to the communication terminal to transmit a digital quantity adjustment signal.

[0037] Specifically, multiple chip flippers are arranged according to the travel direction of the first sliding track 4, and multiple chips can be processed in parallel, which significantly improves production efficiency. This layout enables the glue dispenser 5 to dispense glue for multiple chips in one stroke, reduces the time of repeated positioning, and optimizes the workflow. The main controller 2 connects the glue dispenser 5 and the chip flipper through the power control terminal, and can generate an electrical signal according to the flip angle control signal generated by the direction signal control terminal, so that the running speed of the glue dispenser 5 and the flip speed of the chip flipper can be accurately controlled. This precise control ensures the uniformity and consistency of the glue dispensing process, while avoiding glue dispensing defects caused by improper speed. The communication terminal is connected to the direction signal control terminal, and can generate an emergency control signal to control the signal generation process of the direction signal control terminal. This design provides the function of emergency stop or other emergency operation, enhances the safety and reliability of the equipment, and can respond quickly when an abnormal situation occurs to protect the operator and the equipment. The digital input terminal is connected to the communication terminal for transmitting a digital adjustment signal. This allows the operator or an external system to adjust the parameters of the glue dispenser 5, such as the glue dispensing speed, the glue dispensing amount, etc., through a digital signal, thereby achieving more sophisticated process control. This adjustment capability improves the adaptability and flexibility of the equipment and can meet the dispensing requirements of different products. Through the precise control of the main controller 2, the device can achieve a highly automated dispensing process, reduce manual intervention, and improve production efficiency. The use of digital input terminals makes the adjustment of process parameters simple and quick, and can quickly adapt to different production tasks. The function of emergency control signals provides additional safety for operators and can quickly stop the operation of the equipment in an emergency. Through the communication terminal and digital input terminal, the equipment can be easily integrated with the host computer or factory management system to achieve real-time monitoring and analysis of production data. The design of the chip dispensing device reflects the high attention to automation, precise control and safety, which will help improve the production efficiency and product quality of the electronics manufacturing industry.
