[0024] Example

[0025] like Figure 1 and Figure 2As shown, the SMT pick-and-place machine nozzle anti-static cleaning device proposed in this utility model includes a mounting base 1. Nozzle bodies 2 are connected to both sides of the lower end of the mounting base 1. Electric telescopic rods 3 are connected to both sides of the lower end of the mounting base 1. The electric telescopic rods 3 drive the moving plate 4 to move downward or upward, thereby changing the position of the cleaning component 6. When the nozzle body 2 needs to be cleaned, the electric telescopic rods 3 drive the cleaning component 6 to move downward. When cleaning is not required, the electric telescopic rods 3 drive the cleaning component 6 to move upward, so that the upper end of the moving plate 4 fits against the lower end of the mounting base 1. This ensures that the cleaning component 6 will not affect the normal operation of the nozzle body 2 when not in use. The output end of the electric telescopic rod 3 is connected to the moving plate 4. The upper end of the moving plate 4 has openings on both sides, which facilitate the movement of the moving plate 4 along the outside of the nozzle body 2. Limiting grooves 5 are opened on both sides of the lower end of the moving plate 4. The cleaning component 6 is connected to both sides of the lower end of the moving plate 4.

[0026] like Figure 3 and Figure 4 As shown, the cleaning component 6 includes a support frame 61 installed on both sides of the lower end of the movable plate 4. Limiting blocks 62 are connected to both sides of the upper end of the support frame 61. With the sliding arrangement of the limiting blocks 62 and the limiting grooves 5, the support frame 61 moves circumferentially along the nozzle body 2. The limiting blocks 62 are located inside the limiting grooves 5 and are slidably connected to them. A dual-axis motor 63 is embedded inside the support frame 61. The dual-axis motor 63 uses a dual-core DSP processor dual-axis motor 63 drive system. Two CPUs control two servo motors respectively, and each axis is equipped with an independent control unit to achieve separate control. Therefore, when the dual-axis motor 63 drives the gear 64 to rotate, the first bevel gear 65 does not rotate. The output shaft of the dual-axis motor 63 is fixedly connected to the gear 64, and the output shaft of the other end of the dual-axis motor 63 is fixedly connected to the first bevel gear 65. One end of the gear 64 is meshed with a gear ring 66. When the gear 64 rotates, the gear 64 moves along the outside of the gear ring 66, which in turn drives the support frame 61 to rotate. The upper end of the gear ring 66 is fixedly connected to the lower end of the moving plate 4. The inner opening of the gear ring 66 is larger than the diameter of the opening. When the moving plate 4 drives the gear ring 66 to move, it will not rub against the nozzle body 2.

[0027] Among them, such as Figure 4As shown, the first bevel gear 65 is located inside the support frame 61, and the first bevel gear 65 meshes with the second bevel gear 67. One end of the second bevel gear 67 is fitted with a lead screw 68, and a support plate 69 is sleeved on the outside of the lead screw 68. The support plate provides rotational support for the lead screw 68 to ensure stable rotation of the lead screw 68. The lower end of the support plate 69 is connected to one side of the inside of the support frame 61. The lead screw 68 is threadedly connected to the threaded groove 611. When the lead screw 68 rotates, it drives the telescopic plate 610 to move inward or outward towards the support frame 61. One end of the lead screw 68 is threadedly connected to the telescopic plate 610. The telescopic plate 610 has a threaded groove 611 corresponding to the threaded connection of the lead screw 68. One end of the lead screw 68 is located inside the threaded groove 611. A water storage cavity 612 is opened on one side of the inside of the telescopic plate 610.

[0028] Additionally, a delivery pipe 613 is connected to one side of the water storage cavity 612, which facilitates the delivery or discharge of liquid. One end of the delivery pipe 613 extends through to the outside of the telescopic plate 610. Antistatic liquid is delivered inside the water storage cavity 612 to effectively neutralize the static charge on the surface of the nozzle and reduce particle adsorption. A water-absorbing cotton strip 614 is connected to one side of the water storage cavity 612. The water-absorbing cotton strip 614 delivers the antistatic liquid to the inside of the cleaning cloth 615, keeping the cleaning cloth 615 moist. The cleaning cloth 615 cleans the nozzle body 2 under rapid rotation. The upper end of the water-absorbing cotton strip 614 extends through to the upper end of the telescopic plate 610 and is connected to the cleaning cloth 615. Slider blocks are connected to both sides of one end of the telescopic plate 610. The sliders play a limiting role to prevent the telescopic plate 610 from separating from the support frame 61 during movement, ensuring that the telescopic distance of the telescopic plate 610 is within a controllable range. One end of the slider slides in contact with the inner wall of the support frame 61.

[0029] The implementation principle of the anti-static cleaning device for SMT pick-and-place machine nozzles in this application embodiment is as follows: When cleaning the nozzle body 2 is required, the moving plate 4 is pushed downward by the electric telescopic rod 3, so that the cleaning cloth 615 and the lower end of the nozzle body 2 are at the same horizontal plane. The dual-axis motor 63 drives the first bevel gear 65 to rotate, and the first bevel gear 65 meshes with the second bevel gear 67, which in turn drives the lead screw 68 to rotate. The lead screw 68 is threadedly connected to the telescopic plate 610. The rotation of the lead screw 68 drives the telescopic plate 610 to move to one side of the nozzle body 2, so that the cleaning cloth 615 is in contact with the lower end of the nozzle body 2. At this time, the dual-axis motor 63 drives the gear 64 to rotate, and the gear 64 moves along the outside of the gear ring 66, which in turn drives the support frame 61 to rotate. The support frame 61 drives the cleaning cloth 615 to rotate, thus cleaning the nozzle body 2.

[0030] Dual-axis motors and electric telescopic poles are existing technologies and are widely used in society. The specific models of dual-axis motors and electric telescopic poles can be selected according to production needs and costs, so they will not be described in detail. All electrical components mentioned in this application are connected to an external power supply and control switch during use.

[0031] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
