Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 6 As shown, the present invention provides a nozzle for automated placement of large-size chip materials in SMT, including a nozzle bracket 1;

[0028] The nozzle support 1 is hollow inside. The four corners of the bottom of the nozzle support 1 are connected to the nozzle components 2. The bottom of the nozzle support 1 is fixedly connected to the suction cups 3 surrounding the surface of the nozzle components 2. The top of the nozzle support 1 is provided with a connecting structure.

[0029] refer to Figure 4 The connecting structure includes a nozzle seat 4 sleeved on the top of the nozzle bracket 1, and the nozzle seat 4 and the nozzle bracket 1 are interlocked.

[0030] As a technical optimization of this utility model, the nozzle seat 4 is sleeved on the top of the nozzle bracket 1. The nozzle seat 4 and the nozzle bracket 1 are interlocked, which is simple and quick, easy to install and disassemble, and ensures the stability and reliability of the connection. It also helps to reduce the number of connecting parts, reduce the complexity of the overall structure, and improve the durability and maintenance convenience of the nozzle.

[0031] refer to Figure 4 The top of the nozzle seat 4 is provided with a fixing screw 5. The bottom end of the fixing screw 5 passes through the nozzle seat 4 and the nozzle bracket 1 in sequence and extends into the interior of the nozzle bracket 1. The fixing screw 5 is threadedly connected to the nozzle bracket 1. The interior of the fixing screw 5 is hollow.

[0032] As a technical optimization of this utility model, the setting of the fixing screw 5 not only serves to firmly connect the nozzle seat 4 and the nozzle bracket 1, but also helps to reduce the overall weight or provide additional channels through its hollow internal design. The threaded connection ensures the firmness and stability of the connection, and it is not easy to loosen even during long-term use.

[0033] refer to Figure 3 A reflector 6 is fixedly connected to the bottom of the nozzle holder 4, and the reflector 6 is arranged around the surface of the nozzle bracket 1.

[0034] As a technical optimization of this utility model, the reflector 6 is arranged around the surface of the nozzle bracket 1, which improves the visibility of the nozzle during the mounting process. This helps the operator or equipment to position the nozzle more accurately during the mounting process, ensuring the mounting accuracy. The reflector 6 may also reflect light, improve the utilization efficiency of the light source, and further improve the mounting effect.

[0035] refer to Figure 1 The top of the nozzle seat 4 is provided with a positioning pin 7, and the bottom end of the positioning pin 7 passes through the nozzle seat 4 and the nozzle bracket 1 in sequence and is inserted into the nozzle bracket 1.

[0036] As a technical optimization of this utility model, the connection stability between the nozzle seat 4 and the nozzle bracket 1 is further enhanced by the setting of the positioning pin 7. The insertion of the positioning pin 7 can ensure the accuracy of the nozzle during installation and avoid the installation error caused by improper installation. The positioning pin 7 also plays the role of limiting the movement of the nozzle seat 4 relative to the nozzle bracket 1, so that the connection stability can be maintained even when subjected to external force.

[0037] The working principle and usage process of this utility model: The nozzle support 1 is hollow inside, which helps to reduce the overall weight and may also serve as an air passage, allowing airflow to pass more smoothly through the nozzle components 2. The four corners of the bottom of the nozzle support 1 are connected to nozzle components 2. These nozzle components 2 work together with the suction cup 3 to ensure stable adsorption of large-sized chip materials. The top of the nozzle support 1 is provided with a connecting structure for connecting the nozzle to the placement equipment. The connecting structure includes a nozzle seat 4 sleeved on the top of the nozzle support 1. The nozzle seat 4 and the nozzle support 1 are interlocked. This connection method is simple and quick, and also ensures the stability of the connection. The top of the nozzle seat 4 is provided with a fixing screw 5. The bottom end of the screw passes through the nozzle seat 4 and the nozzle support 1 and extends into the interior of the nozzle support 1, where it is threadedly connected to the nozzle support 1. This fixing method further enhances the firmness of the connection. The top of the nozzle seat 4 is also provided with a positioning... Pin 7, the bottom end of which also passes through nozzle seat 4 and nozzle bracket 1 and is interlocked with nozzle bracket 1, ensures the accuracy of nozzle installation. When the mounting equipment starts, the air pump starts working, providing negative pressure to nozzle component 2 through the hollow channel inside nozzle bracket 1, so that nozzle component 2 and suction cup 3 surrounding its surface can tightly adsorb large-sized chip materials. Since nozzle component 2 is distributed at the four corners of nozzle bracket 1, the weight of the material can be evenly distributed, avoiding the problem of material falling off due to insufficient suction of a single nozzle. During the mounting process, the mounting equipment moves the nozzle with large-sized chip material to the target position according to the preset path and position. After reaching the target position, the air pump adjusts the air pressure, so that nozzle component 2 and suction cup 3 release the adsorption force on the material, thereby placing the material stably in the target position. After the mounting is completed, the nozzle returns to the starting position, ready for the next mounting task.

[0038] In summary, this nozzle for automated placement of large-size SMT chip components is a key component in automated placement equipment. Specifically designed for the precise and efficient placement of large-size chip components, it solves the problem of unstable installation of large, heavy chips such as GPUs on placement machines. By employing a hollow nozzle holder 1 with nozzle components 2 connected to the four bottom corners, the suction force is effectively dispersed, enhancing overall suction stability.
