Description

Technical Field

[0002] In the existing technology, the existing placement machine nozzles need to be replaced with different nozzles for different situations when in use, but the existing equipment cannot be installed conveniently, thus affecting the convenience of use. This is mainly reflected in the following aspects:

[0003] First, the existing nozzles of SMT machines are often inflexible in design, which means that the corresponding nozzles need to be replaced when targeting electronic components of different sizes or shapes. However, there are many inconveniences in the process of replacing nozzles in existing equipment. For example, special tools or equipment may be required to remove and install the nozzles, which not only increases the complexity of the operation, but also easily causes damage to the equipment or nozzles. In addition, the process of replacing the nozzles may take a long time and effort, reducing production efficiency.

[0004] Secondly, the existing nozzles of SMT machines are prone to production interruptions during replacement. Since nozzle replacement requires downtime, this will cause the production line to stagnate, affecting production progress and output. At the same time, frequent downtime to replace nozzles will also increase the cost of equipment repair and maintenance, increasing the operating burden of the company. In addition, due to the inconvenience of replacing nozzles, operators may need to receive special training, increasing labor costs and training costs. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a nozzle for a placement machine, which has the following beneficial effects:

[0018] 1. The design of the connection mechanism makes the installation and replacement process of the SMT nozzle easier and more efficient. Through the synergy of the fixed sleeve, external tube and bellows, a flexible connection between the nozzle and external equipment is achieved. This design allows the operator to quickly connect the insertion tube to the fixed sleeve, and achieve effective sealing through the cooperation of the sealing ring and the sealing groove, reducing the complex steps and time required in the connection process. In addition, the elastic properties of the bellows enable the connection to adapt to equipment in different positions, improving the versatility and adaptability of the equipment.

[0019] 2. The design of the clamping mechanism ensures the stability and reliability of the nozzle during the patch process. A reliable clamping system is formed by the combination of the shrink sleeve and the slider, as well as the setting of the push spring and the pressure block. When sealing is required, the slider moves downward under the action of the push spring, and the pressure block cooperates with the one-way sleeve to ensure the stable sealing of the insertion tube. This design enables the nozzle to be firmly fixed on the equipment, preventing the patch accuracy from decreasing due to vibration or displacement during the patch process, and improving production efficiency and product quality.

[0020] 3. The design of the pushing mechanism allows the sealing strength of the nozzle to be adjusted according to actual needs, so as to adapt to different types of electronic components. Through the cooperation of the threaded sleeve and the thrust bearing, as well as the setting of the anti-slip strip and the hexagonal groove, precise control of the sealing strength is achieved. The operator can adjust the position of the thrust bearing by rotating the threaded sleeve, thereby changing the compression amount of the push spring and adjusting the sealing strength. This design not only improves the convenience of the equipment, but also can maintain the best sealing effect under different working conditions, ensuring the efficient operation of the placement machine and the accurate placement of components.
