Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, specifically to a dispensing machine with an adjustable dispensing angle. Background Technology

[0002] In modern industrial production, dispensing machines, as sophisticated automated equipment, are widely used in numerous fields such as electronics, automotive, medical, and aerospace. They can precisely apply various adhesives, paints, inks, and other fluids to specific locations on products, enabling processes such as encapsulation, fixation, and bonding. The application of dispensing machines not only improves production efficiency but also significantly enhances product quality and consistency, making them an indispensable piece of equipment in industrial production.

[0003] With the continuous development of industrial production and the increasing sophistication of products, the demand for adjustable-angle dispensing machines is growing. Traditional dispensing machines have certain limitations in adjusting the dispensing angle, making it difficult to meet the dispensing needs of complex products. While existing adjustable-angle dispensing machines have solved the problem of dispensing angle adjustment to some extent, they still have some shortcomings.

[0004] Currently, most adjustable-angle dispensing machines rotate around a dispensing head as an axis. This design requires an additional moving mechanism to complete the dispensing task. After the dispensing head rotates, it needs to be moved to the appropriate position via the moving mechanism to align it with the product. This not only increases the complexity and cost of the equipment but also reduces dispensing efficiency and accuracy. Positioning errors may occur during the movement, leading to inaccurate dispensing and affecting product quality.

[0005] Furthermore, to ensure the dispensing head remains aligned with the product after rotation, an ideal method is to rotate the dispensing head around the product as its axis. However, this method faces a serious problem in practical applications: the center of gravity becomes unbalanced during rotation. Due to the structure and installation method of the dispensing head, a significant centrifugal force is generated when it rotates around the product, leading to instability in the center of gravity. Over long-term operation, this imbalance will subject the relevant components of the dispensing machine to additional stress and wear, easily causing equipment damage, increasing maintenance costs and downtime, and affecting the continuity and stability of production.

[0006] In summary, existing adjustable angle dispensing machines have certain deficiencies in structural design and performance, and cannot meet the industrial production requirements for efficient, precise, and stable dispensing. Utility Model Content

The eccentric connecting rod 9 is welded to the point gum head 3 on the end away from the rotating disc 8. The rotating disc 8 is slightly larger in size. The structure gravity center can be concentrated on the rotating disc 8. The influence of the eccentric connecting rod 9 and the point gum head 3 on the rotation can be reduced. The stability of the device can be improved. However, the rotating disc 8 cannot be too large in size. It is difficult to drive the rotation of the rotating disc 8 due to the high quality.

[0033] Further, the rotating disc 8 is provided with the rotating shaft 13 on the side away from the rotating disc 8. The rotating shaft 13 penetrates the main support portion. The rotating shaft 13 is connected to the main support portion through a bearing 14. The rotating disc 8 is provided with a head 10 on the side away from the rotating disc groove 7. The head 10 is provided with a rotating avoiding groove 12 corresponding to the eccentric connecting rod 9. The head 10 is fixedly connected to the main support portion through bolts and a connecting ring 11. The connecting ring 11 and the bolts facilitate the disassembly of the head and the maintenance.

[0061] Working principle: the core components of the dispenser include the workbench 1, glue tank 2, rotating device 4 and dispensing head 3. The workbench 1 is provided with the glue tank 2, and the liquid pump in the glue tank 2 is responsible for conveying the glue to the dispensing head 3 through the pipeline to provide raw materials for dispensing. The rotating device 4 is the key innovation of the dispenser, which includes the main support part, rotating part 5 and driving part 6. The main support part is welded to the workbench 1 to provide stable support for the entire rotating device 4. The rotating part 5 includes a rotating disc 8, an eccentric connecting rod 9 and a rotating shaft 13. The rotating disc 8 is clamped in the rotating disc groove 7 of the main support part and can rotate flexibly. One end of the eccentric connecting rod 9 is welded to the rotating disc 8, and the other end is welded to the dispensing head 3. When the rotating disc 8 rotates, it will drive the eccentric connecting rod 9 and the dispensing head 3 to rotate eccentrically. This design enables the dispensing head 3 to always align with the product during rotation, eliminating the need for secondary movement after rotation and greatly improving dispensing efficiency. At the same time, since there is only one set of driving structure, the maintenance of the device is more simple and convenient. The driving part 6 is responsible for providing power for the rotating part 5, and the driving part 6 includes a driving part housing, a first gear 15, a second gear 16 and a servo motor 17.

The servo motor 17 is coaxially connected to the second gear 16 and fixedly installed on the driving part housing. When the servo motor 17 starts, it will drive the second gear 16 to rotate, and then drive the first gear 15 to rotate through the meshing relationship, finally realize the rotation of the rotating shaft 13 and the rotating disc 8. It is worth noting that the first gear 15 is larger than the second gear 16, and such a design can play a role in speed reduction, improving the accuracy of the angular rotation of the dispensing head 3. The operator only needs to control the rotation of the servo motor 17 to accurately control the rotation angle of the dispensing head 3. In addition, in order to prolong the service life of the device, the dispenser is also provided with a front balance end 18 and a rear balance end 21. The front balance end 18 is coaxially connected to the side of the rotating disc 8 away from the rotating shaft 13, and the front balance bearing 19 at the end is clamped in the front balance groove 20 in the center of the end cap 10. The rear balance end 21 is coaxially connected to the side of the first gear 15 away from the rotating shaft 13, and the rear balance bearing 22 at the end is clamped in the rear balance groove 23 of the driving part housing. Since the dispensing head 3 rotates eccentrically, it will be affected by centrifugal force during rotation to generate potential energy, which may cause the front end of the rotating shaft 13 to be raised or pressed, thereby causing the gear to wear or loosen. The front balance end 18 and the rear balance end 21 can work together to effectively slow down this potential energy and prevent the gear from being worn or loosened, greatly improving the service life of the device.
