Description

Technical Field

[0001] This utility model relates to the field of automated fluid mixing and dispensing technology, and in particular to a vertical high-speed rotation stroke fine adjustment device. Background Technology

[0002] In automated production fields such as precision electronic packaging, semiconductor packaging, medical device manufacturing, and high-end optical component assembly, the application of two-component (such as epoxy resin, polyurethane, silicone, etc.) mixed adhesives is becoming increasingly widespread. These adhesives are typically made by mixing the base material (component A) and the curing agent (component B) in a precise ratio just before use, and then undergoing a chemical reaction to complete curing within a short time.

[0003] A significant characteristic of some two-component adhesives is their rapid curing speed. While this feature is beneficial for improving production efficiency, it also presents a serious challenge: the mixing of components A and B must achieve a highly uniform and thorough mixing process within an extremely short time. Incomplete mixing can lead to unreacted components, air bubbles, or uneven local properties (such as decreased hardness, adhesion, and insulation), ultimately severely impacting product yield and long-term reliability.

[0004] To ensure thorough mixing, modern dispensing technology generally employs dynamic mixing methods, which involve using a drive mechanism to rotate the mixer or its core components (such as stirring blades) at high speed. The strong shear force and turbulence generated by rotation can significantly improve mixing efficiency and shorten mixing time to meet the requirements of fast-curing adhesives.

[0005] However, existing mechanisms for driving dispensing needles or internal stirring blades, while meeting the requirements for high-speed, high-uniformity mixing of two-component adhesives, have the following shortcomings: the gap between the rotor and the stirring chamber cannot be adjusted, making it difficult to accurately control the dispensing volume; and there are issues such as stringing due to untimely dispensing shut-off, and uneven dispensing at the beginning and end of the dispensing process. Utility Model Content

[0006] Given that the gap between the rotor and the mixing chamber cannot be adjusted, resulting in difficulty in accurately controlling the amount of glue dispensed and the inability to collect the glue in a timely manner, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a vertical high-speed rotation stroke fine adjustment device. By cooperating with the stroke adjustment knob and the bearing stop block, a mechanical limiting structure is formed, which can steplessly adjust the transmission shaft, so that the height of the transmission shaft can be raised by 0-5mm, thereby controlling the gap between the stirring rotor and the stirring chamber, and indirectly controlling the amount of glue dispensed, so as to meet the needs of different processes.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vertical high-speed rotation stroke fine adjustment device, including a back plate, a first mounting seat and a second mounting seat connected to the back plate by screws, a motor being provided on the first mounting seat, a stroke seat being threadedly connected to the second mounting seat, a throttle valve being threadedly connected to the stroke seat, a valve body locking nut being connected to the throttle valve, a stroke adjustment knob being connected to the second mounting seat, a coupling being connected to the motor, a drive shaft being connected to the coupling, a bearing stop being slidably connected inside the stroke seat, the drive shaft being located inside the bearing stop, and a bearing bushing being screwed to the bearing stop.

[0009] In a preferred embodiment of the vertical high-speed rotation stroke fine adjustment device of this utility model, the bearing stop is fitted with a spring.

[0010] In a preferred embodiment of the vertical high-speed rotation stroke fine adjustment device of this utility model, the bearing bushing is provided with a small bearing, the circumferential side of the transmission shaft is connected to the small bearing, and the transmission shaft passes through the bearing bushing.

[0011] In a preferred embodiment of the vertical high-speed rotation stroke fine adjustment device of this utility model, a small sealing ring and a large sealing ring are provided between the bearing bushing and the stroke seat.

[0012] In a preferred embodiment of the vertical high-speed rotation stroke fine adjustment device of this utility model, the transmission shaft is threadedly connected to a clamping nut, and the clamping nut abuts against a small bearing.

[0013] In a preferred embodiment of the vertical high-speed rotational stroke fine-tuning device of this utility model, the stroke seat is connected to a grooved transmission hub, the grooved transmission hub is provided with a large bearing, the circumferential side of the transmission shaft is connected to the large bearing, and the transmission shaft passes through the grooved transmission hub.

[0014] The beneficial effects of this utility model are: 1. This utility model uses a stroke adjustment knob and a bearing stop to form a mechanical limiting structure, which can steplessly adjust the transmission shaft, raising the height of the transmission shaft by 0-5mm, thereby controlling the gap between the stirring rotor and the stirring chamber, indirectly controlling the amount of glue dispensed, and adapting to the needs of different processes.

[0015] 2. This utility model uses a spring, a drive shaft, and a grooved drive hub to work together. When the dispensing is finished, the drive shaft falls and the stirring rotor impacts the stirring chamber, forming a mechanical "impact valve closing" to avoid residual glue and stringing.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1:

[0020] Reference Figures 1-2 This is the first embodiment of the present invention, which provides a vertical high-speed rotation stroke fine adjustment device, including a back plate. The back plate is screwed to a first mounting base 1 and a second mounting base 4. The first mounting base 1 is equipped with a motor. The second mounting base 4 is threaded to a stroke seat 3. The stroke seat 3 is threaded to a throttle valve 5. The throttle valve 5 is connected to a valve body locking nut 6. The valve body locking nut 6 can prevent the throttle valve 5 from shifting under the influence of vibration. The second mounting base 4 is connected to a stroke adjustment knob 2. The motor is connected to a coupling 7. The coupling 7 is connected to a drive shaft 8. A bearing stop 10 is slidably connected inside the stroke seat 3. The drive shaft 8 is located inside the bearing stop 10. The bearing stop 10 is screwed to a bearing bushing 14. Example 2:

[0021] Reference Figures 1-2 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a spring 9 is sleeved on the bearing stop 10, one end of the spring 9 abuts against the bearing stop 10, and the other end abuts against the stroke adjustment knob 2.

[0022] The bearing bushing 14 slides together with the bearing stop 10. The bearing bushing 14 is provided with a small bearing 12. The peripheral side of the drive shaft 8 is connected to the small bearing 12. The drive shaft 8 passes through the bearing bushing 14.

[0023] A small sealing ring 15 and a large sealing ring 13 are provided between the bearing bushing 14 and the travel seat 3 to prevent glue and dust from entering the bearing bushing 14.

[0024] The drive shaft 8 is threadedly connected to a clamping nut 11, which abuts against the small bearing 12. The clamping nut 11 prevents the small bearing 12 from moving upward.

[0025] The travel seat 3 is connected to a grooved drive hub 17, which is equipped with a large bearing 16. The circumferential side of the drive shaft 8 is connected to the large bearing 16, and the drive shaft 8 passes through the grooved drive hub 17.

[0026] When in use, the motor starts and drives the transmission shaft 8 to rotate at high speed through the coupling 7. The end of the transmission shaft 8 is threadedly connected to the stirring rotor. The transmission shaft 8 causes the stirring rotor to rotate in the mixing chamber to generate a strong shear flow, thereby achieving dynamic and uniform mixing of the two-component adhesive.

[0027] Compressed air is controlled to enter the stroke seat 3 by the throttle valve 5. The air pressure pushes the bearing bush 14 to move upward. At this time, the spring 9 is compressed, the drive shaft 8 rises, the rotor leaves the bottom of the mixing chamber, the glue outlet opens, and the glue mixes and flows out during rotation.

[0028] When the drive shaft 8 rises to the mechanical limit surface set by the stroke adjustment knob 2, the bearing stop 10 is blocked, the drive shaft 8 stops rising, and a constant gap is maintained to achieve a stable glue output. The rising height of the drive shaft 8 is in the range of 0-5mm. By adjusting the gap between the stirring rotor and the glue outlet of the stirring chamber, the glue output can be finely adjusted.

[0029] After dispensing, the throttle valve 5 releases air, the air pressure disappears, the spring 9 quickly rebounds, pushing the bearing bush 14 downward, the drive shaft 8 falls at high speed, and the rotor hits the bottom of the mixing chamber to close the valve. Through mechanical glue cut-off, residual glue and stringing are avoided.

[0030] The remaining structure is the same as that in Example 1.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
