[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] Example:

[0032] like Figure 1 and Figure 2 As shown, an automatic feeding mechanism for processing a mobile phone metal shell comprises:

[0033] A transplanting mechanism 1, the transplanting mechanism 1 comprising a frame 11 and a transplanting assembly 12 arranged on the frame 11;

[0034] An upper and lower cylinder 2, wherein the upper and lower cylinders 2 are mounted on the transplanting assembly 12 and reciprocate with the transplanting assembly 12; and

[0035] A clamping mechanism 3, the clamping mechanism 3 comprises an air clamp 31 arranged on the upper and lower cylinders 2, two groups of clamping blocks 32 arranged on the air clamp 31, and a blowing assembly 33 rotatably arranged between the two groups of clamping blocks 32;

[0036] The blowing assembly 33 includes a mounting base 331 arranged on the air claw 31, a blowing unit 332 rotatably mounted below the mounting base 331, a plurality of air outlets 333 distributed in a circular array and arranged toward the clamping block 32, and a driving assembly 334 for dynamically connecting the blowing unit 332 and the air claw 31.

[0037] It should be noted that the air claw 31 is installed at the power output end of the upper and lower cylinders 2 through an adapter plate.

[0038] It is also necessary to explain that the upper and lower cylinders 2 are stroke-adjustable cylinders, model TB225×75, brand Chilike; the model of the air claws is HDT20×40, brand Chilike.

[0039] It is important to explain that the upper and lower cylinders 2 can adjust the height of the mobile phone middle frame 100, which facilitates the adjustment and makes the device more compatible with the mobile phone middle frames 100 of different specifications.

[0040] Furthermore, the transplanting assembly 12 includes a linear module 121 disposed on the frame 11 and a base 122 disposed on the linear module 121 and moving with the linear module 121 .

[0041] It should be noted that the model of the linear module 121 is AT100M-4P-L40-1700-LU-M40-P3-3693.

[0042] Furthermore, the clamping block 32 is arranged in an "L" shape, and its clamping surface is knurled.

[0043] It should be noted that the knurling of the clamping surface of the clamping block 32 can increase the friction force and make the clamping more secure.

[0044] Further, such as Figure 4 As shown, the blowing unit 332 includes a hollow rod 3321 rotatably mounted at the bottom of the mounting base 331, a hollow chamber 3322 coaxially arranged at the bottom of the hollow rod 3321, and an air inlet 3323 arranged above the side of the hollow rod 3321 and connected to an external air source, and several groups of air outlets 333 are evenly distributed along the circumference of the hollow chamber 3322.

[0045] It should be noted that the air inlet 3323 is connected to an external air source through a hose.

[0046] Furthermore, the diameter of the hollow rod 3321 is α, the diameter of the hollow chamber 3322 is β, and α<β.

[0047] It should be noted that the hollow chamber 3322 has the ability to store gas, so that the gas volume of the gas outlet 333 is sufficient.

[0048] Furthermore, the air outlet 333 is in a conical shape with a small outside and a large inside.

[0049] It should be noted that the gas outlet 333 is configured in a conical shape, which can increase the gas flow rate and enhance the blowing and cleaning effect.

[0050] Further, such as Figure 3 and Figure 4 As shown, the driving assembly 334 includes a gear 3341 coaxially fixed with the hollow rod 3321, a mounting block 3342 arranged below the mounting seat 331, a T-block 3343 fixedly mounted on the mounting block 3342, a rack 3344 meshing with the gear 3341 and capable of abutting against the moving part of the air claw 31, a T-slot 3345 opened on the back side of the rack 3344 and slidingly matched with the T-block 3343, a baffle 3346 arranged on the side of the mounting seat 331, and a spring 3347 connecting the end of the rack 3344 and the baffle 3346.

[0051] It should be noted that when the air gripper 31 is closed and clamped, the side moving plate of the air gripper 31 contacts the end of the rack 3344, and the rack 3344 moves to drive the gear 3341 and the hollow rod 3321 to rotate.

[0052] It should be further explained that the air gripper 31 can be clamped and released multiple times so as to clean the clamping surface of the clamping block 32 multiple times.

[0053] It is important to note that, as shown in FIG5 , when the clamp block 32 clamps the mobile phone middle frame 100 and delivers the mobile phone middle frame 100 to the positioning fixture, the wind blown out of the air outlet 333 contacts the mobile phone middle frame 100 and changes its direction to blow toward the fixture, thereby ensuring the cleanliness of the positioning surface.

[0054] Working process:

[0055] The moving plate of the air claw 31 contacts the rack 3344 , and the rack 3344 moves to drive the gear 3341 and the hollow rod 3321 to rotate. The wind from the air outlet 333 rotates and blows outwards, thereby cleaning the clamping surface of the clamp block 32 .

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
