The synchronizing element includes, but is not limited to, a flat key.

[0038] Specifically, during the process of the moving drive assembly 2 driving the rod 6 to move vertically, the protrusion is always located in the first elongated groove; during the process of the rotating drive assembly 3 driving the second cylinder 51 to rotate, the second cylinder 51 drives the first cylinder 52 to rotate through the synchronizing element located in the second elongated groove 522 and the third elongated groove 511, and the first cylinder 52 drives the rod 6 to rotate through the protrusion located in the first elongated groove. In this embodiment, the adapter assembly 5 has a simple and compact structure and occupies little space.

[0039] In one embodiment, such as Figure 1 As shown, the moving drive assembly 2 includes a first drive member 21, a first belt 22, and a first pulley 23 and a second pulley 24 spaced apart and mounted on the support member 1. The first belt 22 is sleeved on the first pulley 23 and the second pulley 24. The first drive member 21 is mounted on the support member 1 and connected to the first pulley 23. The first belt 22 is connected to the rod body 6. It can be understood that the first pulley 23, the second pulley 24, and the first belt 22 constitute a synchronous pulley and synchronous belt assembly.

[0040] Specifically, the first driving component 21 drives the first pulley 23 to rotate, and the first belt 22 rotates between the first pulley 23 and the second pulley 24. The first belt 22 drives the rod 6 to move vertically through the belt clamp 72.

Specifically, the rod 6 and the first carrier plate 71 slide on the first guide rail 73 via the first slider 74, thereby ensuring the stability of the rod 6's vertical movement.

[0042] In one embodiment, such as Figure 2 and Figure 3 As shown, the adsorption mechanism further includes an elastic element 9 sleeved on the rod 6. An annular step 62 is provided on the outer wall of the rod 6. The opposite ends of the elastic element 9 abut against the annular step 62 and the first carrier plate 71, respectively. Understandably, the annular step 62 extends outwards from the rod 6. The elastic element 9 includes, but is not limited to, a spring. Specifically, during the process of the rod 6 adsorbing components through the adsorption assembly 4, the adsorption assembly 4 will abut against the components, and the rod 6 will move upwards and compress the elastic element 9. This results in a flexible contact between the adsorption assembly 4 and the components, avoiding damage to the components and the adsorption assembly 4 caused by rigid contact, thus extending the service life of the adsorption mechanism.

[0043] In one embodiment, such as Figure 1 As shown, the rotary drive assembly 3 includes a second drive member 31, a second belt 32, a third pulley 33, and a fourth pulley 34 fixedly sleeved on the second cylinder 51. The second drive member 31 is mounted on the support member and connected to the third pulley 33. The second belt 32 is sleeved on the third pulley 33 and the fourth pulley 34. It can be understood that the third pulley 33, the fourth pulley 34, and the second belt 32 constitute a synchronous pulley and synchronous belt assembly; the second drive member 31 includes, but is not limited to, a motor.

[0046] In one embodiment, such as Figure 5 As shown, the adsorption assembly 4 includes a clamping block 41 with a third through hole 411 and a suction nozzle 42 detachably mounted on the clamping block 41. The second through hole 61 communicates with the suction hole of the suction nozzle 42 through the third through hole 411. Understandably, the clamping block 41 is mounted on the lower end of the rod 6, and the suction nozzle 42 is detachably mounted on the clamping block 41, thus allowing for the installation of different suction nozzles 42 according to different needs and facilitating the replacement of the suction nozzle 42.

[0047] In one embodiment, such as Figure 5 As shown, the clamping block 41 includes a block 412 with the third through hole 411 and a first clamping arm 413 and a second clamping arm 414 rotatably mounted on opposite sides of the block 412.

Understandably, pressing the upper ends of the first clamping arm 413 and the second clamping arm 414 opens their lower ends; releasing the first clamping arm 413 and the second clamping arm 414 closes their lower ends, thus fixing the suction nozzle 42 onto the block 412. In this embodiment, the disassembly and assembly of the suction nozzle 42 and the clamping block 41 is simple.

[0048] In one embodiment, such as Figure 1 As shown, the adsorption mechanism also includes a camera 8 mounted on the support 1. Understandably, the camera can capture the position of the components, thereby facilitating the adsorption of the components by the suction nozzle 42. In this embodiment, the design of the camera 8 improves the automation level of the adsorption mechanism.

[0049] In one embodiment, such as Figure 1As shown, the adsorption mechanism includes two moving drive components, two adsorption components 4, two connecting components 5, and two rods 6, with each component corresponding to the others. The rotary drive component 3 connects to the two connecting components 5. It can be understood that there are two fourth pulleys 34, each sleeved on one of the two second cylinders 51. Thus, the third pulley 33 drives the two fourth pulleys 34 to rotate synchronously via the second belt 32, and the two fourth pulleys 34 drive the two rods 6 to rotate. One rotary drive component 3 can drive the two rods 6 to rotate synchronously. Furthermore, this adsorption mechanism can adsorb two components at a time, improving its working efficiency.
