Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically a dispensing machine with a multi-head dispensing device. Background Technology

[0002] Dispensing machines, also known as glue coating machines, dripping machines, glue spraying machines, or potting machines, are automated machines specifically designed to control fluids and apply them to the surface or interior of products. They can achieve three-dimensional and four-dimensional path dispensing, precise positioning, accurate glue control, and prevent stringing, leakage, and dripping. Dispensing machines are mainly used in product manufacturing processes to accurately dispense, inject, coat, or drip glue, applying it to precise locations on each product. They can be used to apply dots, lines, circles, or arcs.

[0003] Traditional single-head dispensing machines suffer from low efficiency and poor consistency due to point-by-point operation, making it difficult to meet the needs of large-scale production in fields such as electronics and automobiles. The emergence of multi-head dispensing devices has effectively solved this problem. By integrating multiple dispensing heads, they can simultaneously complete dispensing in multiple areas, significantly shortening the production cycle. However, they also have the drawback of being inconvenient to deal with the pungent fumes generated by the glue during use: traditional dispensing machines produce pungent fumes during dispensing, and prolonged exposure to these fumes can easily cause health problems for workers. Therefore, we have proposed a dispensing machine with a multi-head dispensing device. Utility Model Content

[0030] Structural Description:

[0031] Bottom working support platform 1: Bottom working support platform 1 is the basic load-bearing component of the dispensing machine. It is usually a rectangular flat plate with equidistant mounting positions distributed on its top surface to fix the side moving support platform 2 and ensure a stable connection. There is a specific area on the back of the top surface where the exhaust negative pressure component and the dispensing drive component are installed respectively. They are fixed by bolts or welding to provide stable support for other components and ensure the overall structural stability of the dispensing machine.

[0032] Side moving support platform 2: The side moving support platform 2 is generally a long strip structure, which is vertically installed on the top surface of the bottom working support platform 1. The top surface of the platform is fixed with screw rotating support platform 4 at equal intervals. The rotating hole of the screw rotating support platform 4 provides support for the drive screw 5 to ensure its stable rotation. The side moving support platform 2 not only supports the longitudinal moving components, but also enhances the transverse structural strength of the equipment to ensure the stability of each component during dispensing operation.

[0033] Screw Rotation Support Platform 4: The screw rotation support platform 4 is block-shaped and fixed to the top surface of the side movable support platform 2. The rotation hole on its inner side is precision machined, with smooth hole walls and extremely small tolerances. The drive screw 5 passes through the rotation hole and is rotatably connected to it, providing a stable rotation fulcrum for the drive screw 5, reducing friction and shaking during rotation, and ensuring the stable operation of the longitudinal moving component and the precise adjustment of the dispensing position.

[0034] Drive screw 5: The drive screw 5 has a standard thread machined on its surface. One end is connected to the output shaft of the longitudinal drive motor 6, and the other end passes through the rotation hole of the screw rotation support table 4. Under the drive of the longitudinal drive motor 6, the drive screw 5 rotates. Through the cooperation with the threaded hole 18 on the side of the top moving slide 14, the rotational motion is converted into the linear motion of the top moving slide 14, thereby realizing the longitudinal position adjustment of the dispensing head.

[0035] Longitudinal drive motor 6: The longitudinal drive motor 6 is fixed to the rear of the top surface of the side movable support platform 2 and is the power source of the longitudinal moving component. The output shaft of the motor is connected to the drive screw 5 through a coupling to ensure stable power transmission. It receives control signals and precisely controls the rotation direction and speed of the drive screw 5, thereby accurately adjusting the position of the dispensing head in the longitudinal direction to meet the needs of different dispensing trajectories.

[0036] Top moving slide bar 14: The top moving slide bar 14 is a long rod. Its bottom surface is slidably connected to the top surface of the side moving support platform 2 through a slide rail or slide groove structure to ensure smooth movement. Its side has equidistant side threaded holes 18, which are threadedly engaged with the drive screw 5. The top surface of the top moving slide bar 14 fixes and supports the transmission rack 10, and at the same time provides a sliding track for the transverse moving slider 17. It plays a key connection and transmission role in the longitudinal and transverse moving components.

[0037] Support transmission rack 10: The support transmission rack 10 is fixed on the top surface of the top moving slide bar 14. The tooth shape is precisely designed and processed. The length and pitch of the rack are matched with the drive gear 15. When the drive gear 15 rotates under the drive of the transverse drive motor 16, it meshes with the rack to drive the transverse moving slider 17 to slide laterally along the top moving slide bar 14, thereby realizing the transverse position adjustment of the dispensing head.

[0038] Dispensing support platform 12: The dispensing support platform 12 is fixed to the front side of the horizontally moving slider 17 and has a plate-like structure. Its top surface has equally spaced dispensing head fixing holes 20 for installing the dispensing head 13 tightly to ensure that the dispensing head is installed firmly. At the same time, the top surface is also provided with negative pressure pipe fixing holes 19 for connecting the negative pressure air extraction pipe 9 to extract pungent gas during the dispensing process and protect the working environment.

[0039] Drive gear 15: Drive gear 15 is mounted on the output shaft of transverse drive motor 16 and meshes with support transmission rack 10. The tooth profile and module of the gear are adapted to the rack. Under the drive of transverse drive motor 16, drive gear 15 rotates, converting the rotational motion of the motor into the linear motion of transverse moving slider 17, which drives dispensing support table 12 and dispensing head to move laterally, thereby achieving precise dispensing position adjustment.

[0040] Horizontal drive motor 16: The horizontal drive motor 16 is fixed in the mounting slot at the top of the horizontal moving slider 17. It is the power source of the horizontal moving component. The motor receives control signals and precisely controls the rotation direction and speed of the drive gear 15, thereby controlling the moving direction and distance of the horizontal moving slider 17, so as to realize the precise adjustment of the dispensing head in the horizontal direction to meet the needs of different dispensing operations.

[0041] Lateral movement slider 17: The lateral movement slider 17 is sleeved on the outside of the top moving slider 14. It has a sliding structure adapted to the top moving slider 14, such as a smooth sleeve or roller, to ensure smooth sliding and high precision. A lateral drive motor 16 is installed on the top of the slider and a dispensing support platform 12 is fixed on the front. Under the action of the drive gear 15 and the support transmission rack 10, the lateral movement is realized, which drives the dispensing support platform 12 and the dispensing head to complete the lateral position adjustment.

[0042] Negative pressure exhaust fan 7: The negative pressure exhaust fan 7 is fixed on the top surface of the bottom working support platform 1. The main body consists of a fan shell, a motor and an impeller. The motor drives the impeller to rotate at high speed, creating negative pressure inside the fan and generating suction. The front side is connected to the negative pressure exhaust pipe 9, which is used to extract the pungent gas generated by the dispensing operation. The exhaust port on the back is equipped with a filter screen 22 to purify the exhaust gas and improve the working environment.

[0043] Negative pressure exhaust pipe 9: Negative pressure exhaust pipe 9 is usually a flexible or rigid pipe. One end is tightly connected to the air outlet on the front side of the negative pressure exhaust fan 7, and the other end is fixed in the negative pressure pipe fixing hole 19 on the top surface of the dispensing support table 12. The pipe has good sealing performance to prevent gas leakage and ensure that the pungent gas generated during the dispensing process can be effectively extracted and transported to the negative pressure exhaust fan 7 for treatment.

[0044] Filter plate 22: The filter plate 22 is installed inside the exhaust port on the back of the negative pressure exhaust fan 7. It is made of multiple layers of filter materials, such as activated carbon layer and fiber filter. It can effectively intercept harmful substances in the gas, such as organic pollutants generated by glue volatilization, purify the exhaust gas, avoid pollution to the environment, and protect the health of the staff.

[0045] Adhesive storage box 8: The adhesive storage box 8 is fixed on the back of the top surface of the bottom working support platform 1. It is a sealed container with a certain capacity and strength. It is used to store adhesive. The storage box is generally equipped with an inlet and an outlet. The outlet is connected to the high-pressure drive pump 21 to ensure that the adhesive is not contaminated by the outside during storage and to continuously provide adhesive for dispensing operations.

[0046] Adhesive conveying pipeline 11: Adhesive conveying pipeline 11 connects high-pressure drive pump 21 and dispensing support platform 12. The inner wall of the pipeline is smooth to reduce the resistance and residue of adhesive during the conveying process. The pipeline has a certain degree of flexibility and corrosion resistance, and can adapt to the vibration during equipment operation and the chemical properties of adhesive, ensuring that adhesive is smoothly conveyed from adhesive storage tank 8 to the tight dispensing head 13 to meet the dispensing operation requirements.

[0047] Precise dispensing head 13: The precise dispensing head 13 is fixed in the dispensing head fixing hole 20 on the top surface of the dispensing support platform 12. It has a fine dispensing control structure inside, such as a needle valve or a micro-orifice nozzle. Under the action of the high-pressure drive pump 21, the adhesive is extruded through the dispensing head to achieve precise dispensing. It can control the dispensing amount and dispensing shape according to different dispensing process requirements to ensure dispensing quality.

[0048] High-pressure drive pump 21: The high-pressure drive pump 21 is fixed on the back of the top surface of the bottom working support platform 1 and connected to the front side of the adhesive storage tank 8. The pump has a pumping structure such as a piston or impeller inside. Driven by a motor, it draws the adhesive from the storage tank and pressurizes it so that it can be quickly and stably delivered to the dispensing head 13 through the adhesive delivery pipe 11, providing sufficient power for the dispensing operation and ensuring that the dispensing process is smooth.

[0049] Working principle: Before starting the equipment, the adhesive is pre-stored in the adhesive storage tank 8. After starting the equipment, the high-pressure drive pump 21 starts working, which extracts the adhesive from the adhesive storage tank 8 and transports it to the dispensing head 13 through the adhesive conveying pipe 11, providing material preparation for the dispensing operation. When it is necessary to adjust the longitudinal position of the dispensing head, the longitudinal drive motor 6 starts, and its output shaft drives the drive screw 5 to rotate. Since the screw rotation support platform 4 supports and positions the drive screw 5, and the drive screw 5 is threadedly connected to the side threaded hole 18 on the side of the top moving slide 14, when the drive screw 5 rotates, the top moving slide 14 moves... The slide bar 14 moves longitudinally along the top surface of the side movable support platform 2, thereby adjusting the position of the dispensing head in the longitudinal direction. After the longitudinal position adjustment is completed, if further adjustment of the lateral position of the dispensing head is required, the lateral drive motor 16 is started. The output shaft of the lateral drive motor 16 drives the drive gear 15 to rotate. The drive gear 15 meshes with the support transmission rack 10 fixed on the top surface of the top movable slide bar 14. In this way, the lateral moving slider 17 connected to the drive gear 15 moves laterally along the outer side of the top movable slide bar 14. The dispensing support platform 14 installed in front of the lateral moving slider 17... 2. The dispensing head fixed on the dispensing support platform 12 also moves laterally to adjust its lateral position. Through the cooperation of the longitudinal and lateral moving components, the dispensing head can accurately move to the designated position according to different dispensing trajectory requirements. After the dispensing head moves to the target position, the high-pressure drive pump 21 continuously pressurizes the adhesive through the adhesive delivery pipe 11 to the compact dispensing head 13. The compact dispensing head 13 dispenses or coats the adhesive onto the product surface or interior according to the set parameters. Since the equipment is designed with multiple sets of compact dispensing heads 13, they can work simultaneously to achieve multi-head dispensing and improve production efficiency. To improve production efficiency, during the dispensing process, the adhesive will produce a pungent gas. At this time, the negative pressure exhaust fan 7 will start, generating suction through the negative pressure exhaust pipe 9. One end of the negative pressure exhaust pipe 9 is connected to the negative pressure exhaust fan 7, and the other end is fixed in the negative pressure pipe fixing hole 19 on the top surface of the dispensing support table 12. This effectively sucks in the pungent gas generated in the dispensing area. The sucked-in gas is filtered by the filter screen 22 at the exhaust port on the back of the negative pressure exhaust fan 7, intercepting harmful substances. The purified gas is then discharged into the external environment, preventing the spread of pungent odors and protecting the health of the workers.
