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.
[0024] Please see Figure 1-6 This utility model provides a technical solution: a suction nozzle for automated placement of battery holder materials in SMT, including a suction nozzle seat 2 and a fixing screw 1 set on the upper end of the suction nozzle seat 2. A reflector 3 is provided on the lower surface of the suction nozzle seat 2, and a suction nozzle bracket 4 is provided below the reflector 3. An adjustment bracket 5 is sealed to one side of the suction nozzle bracket 4, and a stroke adjustment screw 6 is rotatably provided on one side of the adjustment bracket 5. A suction nozzle 7 is provided on the lower surface of the suction nozzle bracket 4. A sealing ring 9 is provided at the connection between the suction nozzle bracket 4 and the suction nozzle 7. A second sealing gasket 10 is provided on the outside of the sealing ring 9. A spring 11 is provided on the outside of the second sealing gasket 10 at the connection between the suction nozzle bracket 4 and the suction nozzle 7.
[0025] exist Figure 4 In the middle: A first sealing gasket 8 is provided at the connection between the lower surface of the reflector 3 and the nozzle bracket 4. This arrangement can improve the sealing of the connection between the reflector 3 and the nozzle bracket 4 by using the first sealing gasket 8.
[0026] exist Figure 1 In the middle: The upper surface of the nozzle holder 2 has two symmetrical "U"-shaped slots above the reflector 3. This setting can be used to install the equipment.
[0027] exist Figure 1 and Figure 4 In the middle: A sealing ring is provided on the inner side of the adjustment bracket 5 outside the stroke adjustment screw 6. One end of the stroke adjustment screw 6 contacts the outer side of the nozzle 7. This setting utilizes the rotation of the stroke adjustment screw 6 to move the nozzle 7, thereby adjusting the position of the nozzle 7 to meet the needs of battery holders of different sizes.
[0028] exist Figure 6 In the middle: The suction nozzle 7 is made of ceramic or hard alloy. This setting uses high-quality materials that are wear-resistant and corrosion-resistant, which improves the durability and stability of the suction nozzle 7.
[0029] exist Figure 4 In the middle: one end of the spring 11 is fixed to the outside of the suction nozzle 7, and the other end of the spring 11 is fixed to the outside of the second sealing gasket 10. This setting uses the elastic force of the spring 11 to adjust the stroke, and its internal design includes a sealing ring 9 to achieve the continuity of vacuum.
[0030] exist Figure 4 , Figure 5 and Figure 6 In the middle: the nozzle support 4 has a first channel 41 inside, and the nozzle 7 has a second channel 71 that communicates with the first channel 41. This arrangement uses the interconnected first channel 41 and second channel 71 to achieve the purpose of air suction to form negative pressure, so as to achieve the purpose of suction of the battery holder.
[0031] During operation (or use), when the suction surfaces of battery holders of different sizes are different, the suction nozzle 7 can be moved by adjusting the stroke adjustment screw 6, thereby adjusting the distance between the two suction nozzles 7. When the suction nozzle 7 moves, the spring 11 will deform, that is, the stroke adjustment is achieved by using the elastic force of the spring 11. The internal design has a sealing ring 9 and a second sealing gasket 10 to achieve the continuity of vacuum. After adjustment, it is installed on the pick-and-place machine. When the suction nozzle 7 moves above the battery holder material, the negative pressure system is activated, and the head of the suction nozzle 7 generates negative pressure, adsorbing the material onto the suction nozzle 7.
[0032] Movement: Driven by the pick and place machine, the nozzle 7 carries the material to the designated placement position.
[0033] Release: Upon reaching the designated position, the negative pressure system shuts off, and the suction nozzle 7 releases the material, placing it accurately on the circuit board.
[0034] The steps for using this nozzle 7 are not fixed and can be reasonably adjusted according to the production process. Its overall structure is simple, which improves the reliability and service life of the product. At the same time, the nozzle has a wide range of applications, low cost, and adjustable suction power, making it very suitable for automated non-destructive mounting.
[0035] During the placement process, the stability and accuracy of the placement can be further improved by adjusting parameters such as the pick-up speed and placement speed.
[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
