[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the embodiments without creative effort are all within the protection scope of this utility model.

[0023] Please see Figure 1-5 An SMT (Surface Mount Technology) component adsorption device includes a control base 1, a lifting block 6 mounted on the control base 1 via a lifting assembly, and an adsorption mechanism mounted on the lifting block 6. The adsorption mechanism includes: a buffer assembly mounted on the bottom of the lifting block 6 and having elasticity; a mounting block 15 mounted on the buffer assembly and having a mounting groove 18 on its bottom end face; a suction nozzle 16, with its top end passing through the mounting groove 18 via a sealing element and having a slot 19 on its side; a fixing assembly mounted on the mounting block 15 and capable of passing through the slot 19; and a vacuum assembly mounted on the lifting block 6 and connected to the inside of the mounting groove 18.

[0024] like Figure 1-5 As shown, when using the pick-and-place machine, the nozzle 16 needs to be replaced according to the usage requirements. The nozzle 16 installed on the mounting block 15 is directly removed, and the new nozzle 16 is inserted into the mounting groove 18 through the sealing member, which ensures the sealed connection between the nozzle 16 and the mounting groove 18. This facilitates the vacuum assembly to control the vacuum operation of the nozzle 16, and the control fixing component is inserted into the slot 19 opened on the side of the nozzle 16, which facilitates the fixing of the nozzle 16 in the mounting groove 18. This allows for convenient replacement of the pick-and-place machine nozzle 16 and improves the replacement efficiency of the nozzle 16.

[0025] like Figure 5As shown, in this embodiment, the sealing element includes a sealing ring, which is disposed on the top of the suction nozzle 16. When the suction nozzle 16 is inserted into the mounting groove 18, the sealing ring is located on the bottom wall of the suction nozzle 16 and the mounting groove 18. The sealing ring can be made of rubber. It is placed on the bottom wall of the mounting groove 18 and then the suction nozzle 16 is inserted into the mounting groove 18, which ensures the sealing of the connection between the suction nozzle 16 and the mounting groove 18 and ensures that the vacuum assembly controls the suction nozzle 16 to draw a vacuum.

[0026] like Figure 5 As shown, in this embodiment, the fixing component includes: a fixing screw 17, which is threadedly connected to the side of the mounting block 15, and one end of which passes through the mounting groove 18; a locking block 20 is provided on the end of the fixing screw 17 that passes through the mounting groove 18, and the locking block 20 is movably inserted into a hole opened in the groove wall of the mounting groove 18. When the suction nozzle 16 passes through the mounting groove 18, the end of the fixing screw 17 passes through the locking groove 19, and the suction nozzle 16 passes through the mounting groove 18. Rotating the fixing screw 17 rotates the suction nozzle 16, and the end of the fixing screw 17 passes through the locking groove 19. The locking block 20 provided on the end of the fixing screw 17 passes through the locking groove 19 to fix the position of the suction nozzle 16 in the mounting groove 18. This facilitates the installation of the suction nozzle 16 and ensures the stability of the suction nozzle 16 installed in the mounting groove 18.

[0027] The buffer assembly includes: a telescopic tube 13, which is disposed between the lifting block 6 and the mounting block 15, and whose two ends are respectively connected to the inside of the lifting block 6 and the mounting groove 18; and a buffer spring 14, which is sleeved on the body of the telescopic tube 13, and whose two ends are respectively connected to the lifting block 6 and the mounting block 15.

[0028] The vacuum assembly includes: a control tube 11, which is vertically mounted on the lifting block 6 and has a sealing disc 22 that is slidably mounted inside; a control component, which is mounted on the lifting block 6 and can control the sealing disc 22 to slide inside the control tube 11; one end of the control tube 11 is connected to a gas supply channel opened inside the lifting block 6 through a connecting pipe, and the gas supply channel is connected to and communicates with the inside of the telescopic tube 13.

[0029] The control components include: a control rod 21, which passes through the control tube 11 and is connected at one end to a sealing disc 22; a control disc 10, which is located at the end of the control tube 11 and has a rotating block vertically arranged on its end face offset from the center; a vacuum motor 9, which is mounted on the lifting block 6 and controls the rotation of the control disc 10; the end of the rotating block away from the control disc 10 is rotatably connected to the end of the control rod 21, and the end of the control tube 11 is connected to the gas supply channel through a connecting pipe 12.

[0030] like Figure 1-4As shown, when working through the suction nozzle 16, the vacuum motor 9 drives the control disk 10 to rotate. The rotating block set on the control disk 10 drives the control rod 21 to move inside the control tube 11, and drives the sealing disk 22 to slide and seal inside the control tube 11. This facilitates the control of air being drawn into the control tube 11 from the suction nozzle 16 or air being pushed into the suction nozzle 16, thus realizing the suction operation of the suction nozzle 16.

[0031] The control base 1 has a vertically oriented sliding groove 2 on its side. The lifting assembly includes: a slide rod 3, which passes through the sliding groove 2 vertically; a slider 4, which is movably sleeved on the slide rod 3 and connected to the lifting block 6; a limit spring 5, which is movably sleeved on the slide rod 3 and located below the slider 4, with its two ends connected to the slider 4 and the groove wall of the sliding groove 2 respectively; and a lifting component, which is set on the lifting block 6 and controls the slider 4 to slide downward on the slide rod 3.

[0032] The lifting component includes: a rotating rod 7, which is horizontally mounted on the control base 1, and a roller 8, which is rotatably mounted at one end, is located on the top of the lifting block 6; and a rotating column, which is mounted on the center of the side of the rotating rod 7 near the control base 1 and is driven by a motor.

[0033] like Figure 1-3 As shown, in this embodiment, the suction nozzle 16 works in conjunction with the lifting component to move the suction nozzle 16 up and down. During the downward movement of the suction nozzle 16, the motor drives the rotating column to rotate the rotating rod 7 around the center. At this time, the roller 8 set on one end of the rotating rod 7 abuts against the lifting block 6 and moves downward. The slider 4 set on the lifting block 6 slides stably on the sliding rod 3 and compresses the limiting spring 5 on the sliding rod 3, thereby ensuring that the lifting block 6 moves up and down stably. After the suction nozzle 16 completes the suction operation, the power supply to the motor is disconnected. Under the action of the limiting spring 5, the slider 4 will be pushed to move upward, that is, the lifting block 6 will be moved upward, and the suction nozzle 16 will be controlled to return to its original position.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
