When assembling the suction cup assembly, the spring 14 needs to be sleeved on the screw of the suction nozzle 12. In the prior art, the assembly of the spring 14 of the suction cup assembly is usually done manually, which has the disadvantages of low work efficiency and waste of manpower.

[0061] Therefore, this application proposes a spring installation mechanism, see Figure 4 , Figure 6 and Figure 7 As shown, the spring installation mechanism provided in the embodiment of the present application includes a spring feeding mechanism 20, a base 30 and a driving member 40, at least one installation station is provided on the base 20, and each installation station is provided with a material receiving member 50 and a material control component 60, wherein:

[0062] The material receiving member 50 is fixedly mounted on the base 30, and the lower end of the material receiving member 50 passes through the base 30. The material receiving member 50 has a conveying channel 51 that passes through the upper and lower parts. The conveying channel 51 can accommodate at least two springs to be installed in a stacked manner. The upper end of the conveying channel 51 is connected to the discharge end of the spring feeding mechanism 20. The spring feeding mechanism 20 is used to provide the springs to be installed into the conveying channel 51.

[0063] The fixed end of the driving member 40 is mounted on the base 30, and the driving end of the driving member 40 is connected to the material control assembly 60. The driving member 40 is used to drive the material control assembly 60 to move in a first direction (eg Figure 6 The material control assembly 60 is reciprocated in the X direction so that the material control assembly 60 is alternately moved to the first position or the second position;

[0064] When the driving member 40 drives the material control assembly 60 to move to the first position, the material control assembly 60 is configured to support the bottom end of the first spring 70. The first spring 70 is the bottommost spring in the conveying channel 51 to support all the springs in the conveying channel 51.

[0065] When the driving member 40 drives the material control assembly 60 to move to the second position, the material control assembly 60 is configured to release the support for the first spring 70 and fix the second spring 71 in the conveying channel 51 at the same time. The second spring 71 is the spring adjacent to the first spring 70 in the conveying channel 51, so that the first spring 70 flows out of the conveying channel 51 by its own weight and sleeves on the screw of the nozzle located directly below the conveying channel 51.

Both the first avoidance hole and the second avoidance hole are communicated with the conveying channel 51. The value range of the height difference H between the support member 62 and the pressing member 63 is: h < H < 2h, where h is the height of a single spring.

[0068] When the driving member 40 drives the material control assembly 60 to move to the first position, the pressing member 63 leaves the conveying channel 51, and the support member 62 passes through the first avoidance hole and enters the conveying channel 51 to support the first spring 70 at the bottom end of the first spring 70, thereby supporting all the springs in the conveying channel 51.

[0072] Optionally, the first avoidance hole is arranged through the material receiving member 50 in the first direction, so that when the material control assembly 60 moves to the first position, the support member 62 can fully extend into the material receiving member 50 to fully support the bottom surface of the first spring 70.

[0073] Through the cooperation of the driving member 40, the mounting seat 61, the supporting member 62, the tightening member 63 and the material receiving member 50, the material receiving member 50 releases one spring each time, and the released spring falls by its own weight and is sleeved on the screw of the suction nozzle directly below, providing a material control component with simple structure, low cost and precise control.

[0074] As an implementation manner, the support member 62 is fixedly mounted on the mounting seat 61 , and one end of the support member 62 close to the material receiving member 50 is used to support the first spring 70 , and one end of the support member 62 close to the material receiving member 50 is a pointed structure.

[0075] By configuring one end of the support member 62 close to the material receiving member 50 to have a pointed structure, the support member 62 can smoothly pass through the first avoidance hole and extend under the first spring 70 .

7. The spring mounting mechanism according to claim 2, characterized in that: One end of the pressing member close to the material receiving member is a planar structure.

8. The spring mounting mechanism according to claim 1, characterized in that: Two installation stations are spaced apart on the base, and the driving member drives the material control components on the two installation stations to synchronously reciprocate along the first direction, so that the material control components on the two installation stations are synchronously moved to the corresponding first position or the second position.

9. The spring mounting mechanism according to claim 1, characterized in that: The spring feeding mechanism includes a vibrating plate and at least one discharge pipe connected to the vibrating plate, the discharge pipe is connected to the material receiving piece in a one-to-one correspondence, and the vibrating plate is used to sequentially input the springs to be installed into the material receiving piece through the discharge pipe.

10. A suction cup assembly machine, characterized in that: The suction cup assembly machine includes a spring mounting mechanism as described in any one of claims 1-9.
