[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] As attached Figure 1 and Figure 4 The recessed nozzle of a placement machine shown in the figure comprises a suction rod 1, the top of which is provided with a joint 101 connected to a placement machine body 2;

[0026] The suction structure 3 is detachably mounted on the bottom of the suction rod 1 and includes a suction head 301, a groove 302, and a suction hole 303. The groove 302 is provided at the bottom of the suction head 301, and the suction hole 303 is provided in the groove 302 to communicate with the suction rod 1.

[0027] The protective component 4 is arranged in the groove 302, including a rubber structure 401, a sliding structure 402 and a limiting structure 403. The limiting structure 403 is arranged on the sliding structure 402 to clamp the rubber structure 401. The rubber structure 401 is provided with an opening 404 adapted to the suction hole 303.

[0028] The suction rod 1 is available in multiple lengths to accommodate various operating requirements. The connector 101 is detachably connected to the SMT machine body 2, making it easy to maintain and replace the suction rod 1. A snap-in slot is located at the bottom of the suction rod 1, and a snap-in piece is located at the top of the suction head 301 to engage with the slot. A locking piece is also located at the connection to increase the coupling strength. The detachable connection facilitates maintenance and replacement of the suction head 301, saving time, effort, and costs. Multiple groups of suction holes 303 are arranged in a certain sequence within the groove 302 to connect with the suction rod 1. The suction rod 1 uses negative pressure to absorb the patch. The sliding structure 402 includes a slide groove provided on the inner wall of the groove 302 and a sliding block slidably connected thereto. The sliding block is connected to the limiting structure 403, and the two are connected by a snap connection or a threaded connection. The limiting structure 403 is provided with a clamping part to fix the rubber structure 401. A friction resistance part is also provided between the sliding block and the slide groove. The friction resistance part can lock the position of the sliding block in the slide groove when the sliding block is not subjected to external force. The external force is the pressure of the equipment fitting. When the pressure is too large, the rubber structure 401 will be squeezed and deformed, thereby driving the sliding block to slide on the slide groove. A coupling tube is also provided between the suction hole 303 and the opening 404. The size of the coupling tube is slightly smaller than the size of the opening 404. The coupling tube can connect the suction hole 303 with the opening 404. A sealing structure is also provided at the connection between the three to improve the sealing.
