Description

TECHNICAL FIELD

[0001] The utility model relates to automatic fluid dispensing equipment technical field, concretely relates to a device of automatic cleaning nozzle and needle nozzle. BACKGROUND

[0002] In automatic dispensing equipment, nozzles or needle nozzles are one of the key components, which are responsible for accurately dispensing glue to designated locations. However, in actual operation, especially in mass production, the nozzle or needle tip often has residual glue. These residues not only affect the accuracy and quality of the next dispensing, but also may cause glue splashing, surface drying and clogging, etc., thereby affecting the final quality of the product.

[0003] To address the above problems, the traditional approach is to use a vacuum suction mode to remove residual glue from the nozzle or needle. Although this method can remove larger glue residues to some extent, it has obvious limitations: the vacuum pipeline is easily clogged by solidified glue, which gradually weakens the vacuum effect and ultimately affects the cleaning efficiency and quality. In addition, frequent manual intervention also increases maintenance costs and time, reducing overall production efficiency.

[0004] Limitations of the prior art:

[0005] 1. Limited cleaning effect: The traditional vacuum suction method can only handle larger particle glue residues, and the cleaning effect on fine residues is poor, which cannot ensure the consistency and quality of each dispensing.

[0006] 2. Poor system stability: Over time, the vacuum pipeline will be clogged by solidified glue, causing the vacuum system to degrade in performance and even fail, requiring regular cleaning and increasing maintenance difficulty and cost.

[0007] 3. Dependence on manual operation: Traditional cleaning methods often require human intervention, which not only increases labor costs, but also may affect the cleaning effect and production continuity due to human factors.

[0008] 4. Lack of intelligent control: Without automatic sensing and control systems, the cleaning process cannot be automatically adjusted according to actual conditions, and the adaptability is poor.

[0009] Therefore, the prior art has limitations and needs further improvement. Utility model content

[0076] The principle of this utility model is as follows:

[0077] 1. Induction and activation

[0078] Optical fiber sensor 16: The optical fiber sensor 16 installed on the side of the mounting base 1 monitors in real time whether the nozzle or needle of the dispensing equipment reaches the set cleaning position. When the nozzle or needle approaches, the optical fiber sensor 16 transmits a signal to the control circuit board 15.

[0079] MCU microcontroller unit 17: After receiving the signal from the optical fiber sensor 16, the MCU (microcontroller unit) starts processing and issuing instructions, preparing to start the cleaning process.

[0080] 2. Alcohol supply

[0081] Alcohol peristaltic pump 4: According to the instructions from the MCU, the alcohol peristaltic pump 4 injects an appropriate amount of alcohol into the cleaning solvent tank 9 through the solvent input pipe 13. The position of the solvent input pipe 13 is lower than that of the solvent output pipe 14, ensuring that the alcohol can flow smoothly into the cleaning solvent tank 9 without spilling.

[0082] Timing control: The user can adjust the time of the alcohol peristaltic pump 4 delay in supplying alcohol through the timing setting button 23 to adapt to different types of glue and cleaning needs. The three-digit nixie tube 22 is used to display the current set delay time.

[0083] 3. Mechanical transmission and cleaning

[0084] Motor 5 drive: The MCU sends a start signal to the motor 5 at the same time, and the motor 5 starts to operate. The motor 5 has a driving wheel 6 installed on its rotating shaft, which is connected to the transmission wheel 7 on the cloth belt wheel 2 through the synchronous shaft 12, forming a complete transmission system.

[0085] Cleaning cloth belt 3 movement: The rotation of the motor 5 drives the driving wheel 6 to rotate, which in turn drives the cloth belt wheel 2 to rotate through the transmission system, and finally drives the cleaning cloth belt 3 to move continuously in the cleaning solvent tank 9. The cleaning cloth belt 3 is wetted by the alcohol and wipes the surface of the nozzle or needle as it moves, removing the residual glue.

[0086] 4. Control system

[0087] Control circuit board 15: As the nerve center of the entire system, the control circuit board 15 integrates multiple key components, including the MCU microcontroller unit 17, the input isolation integrated optical coupling module 18, the 5V voltage stabilizer 19, the output drive integrated transistor module 20, and the decoding drive chip 21. These components work together to ensure accurate signal transmission between components and achieve precise control of the cleaning process.

[0088] Feedback mechanism: the signal from the optical fiber sensor 16 is received through the input isolation integrated optical coupling module 18 to ensure that external interference does not affect the normal operation of the system; and the output drive integrated transistor module 20 is responsible for driving the motor 5 and the alcohol peristaltic pump 4 to perform specific cleaning actions.

[0089] 5. Safety and environmental protection

[0090] Solvent management: the design that the solvent input pipe 13 is lower than the solvent output pipe 14 prevents accidental overflow of the alcohol solution, ensuring safety and reducing resource waste.

[0091] In summary, the automatic cleaning nozzle and needle device realizes the automatic and intelligent cleaning of the nozzle or needle by integrating advanced sensing technology, intelligent control system and efficient mechanical transmission structure, effectively solves the problems existing in the traditional cleaning method, and improves the glue dispensing quality and production efficiency.
