[0089] The outer wall of the second body 40 is formed with a circumferentially extending clearance groove 43, and the synchronous belt 421 is arranged in the clearance groove 43. The synchronous belt 421 is arranged around the second body 40. By providing the circumferentially extending clearance groove 43, the synchronous belt 421 can be arranged around the second body 40 in the clearance groove 43, and the spatial layout is reasonable, so that the synchronous belt 421 and the second body 40 are compactly installed and occupy a small space.

[0090] like Figure 14 As shown, the present invention further discloses an intelligent platform system 70, including the functional head, and the intelligent platform system 70 is a material taking device or an assembly device.

[0091] Working principle of the present invention:

[0092] 1. The suction pipe 60 moves downward: The gas output by the external positive pressure device P2 passes through the second positive pressure air hole 122, the positive pressure main pipe 12, the port 123, the second positive pressure main chamber 401, the second positive pressure branch channel (not shown), the fifth air path B5, the third channel A3, and the drive chamber 522 in sequence, so that the gas in the drive chamber 522 pushes the piston head 53 to move downward, and the piston head 53 drives the suction pipe 60 to move downward;

[0093] 2. The suction pipe 60 moves upward: the external positive pressure device P2 stops supplying air, the pressure spring 54 pushes the piston head 53 upward, and the piston head 53 drives the suction pipe 60 upward. When the piston head 53 moves upward, the gas in the driving chamber 522 is compressed, so that the gas in the driving chamber 522 is discharged into the atmosphere P0 through the third channel A3 and the sixth gas path B6 in sequence.

[0094] 3. Material extraction through the suction pipe 60: Air passes through the suction head 64, the suction pipe 60, the first channel A1, the first air path B1, the negative pressure diversion channel (not shown), the negative pressure main chamber 34, the first negative pressure air hole 131, the negative pressure main pipe 13, the second negative pressure air hole 132, and the external negative pressure device P1 in sequence, creating a negative pressure state inside the suction pipe 60, thereby causing the suction head 64 to absorb the material;

[0095] 4. Breaking the vacuum in the suction pipe 60: The gas output by the external positive pressure device P2 passes through the second positive pressure air hole 122, the positive pressure main pipe 12, the first positive pressure air hole 121, the first positive pressure main chamber 33, the first positive pressure branch channel (not shown), the third air path B3, the second channel A2, the second air path B2, the first channel A1, the suction pipe 60, and the suction head 64 in sequence, forming a positive pressure state inside the suction pipe 60, breaking the vacuum inside the suction pipe 60, and thus releasing the sucked material;

[0096] 5. The suction pipe 60 is not working: the atmosphere P0, the fourth air path B4, the second channel A2, the second air path B2, the first channel A1, the suction pipe 60, and the suction head 64 are connected in sequence, so that the interior of the suction pipe 60 is at normal pressure. At this time, the suction pipe 60 does not absorb material and does not break the vacuum;

[0097] 6. Assemble the product: The second drive mechanism 11 drives the suction body 20 to move downward, so that the first body 30, the second body 40, the rotary drive mechanism 42 and the suction pipe 60 move downward synchronously, the first drive mechanism 50 drives the corresponding suction pipe 60 to move downward, the suction head 64 absorbs the material, the first drive mechanism 50 drives the suction pipe 60 to move upward again, the suction pipe 60 drives the material to move upward, the second motor drives the synchronous belt 421 to rotate, the synchronous belt 421 drives all the synchronous pulleys 61 to rotate at the same time, all the suction pipes 60 rotate around their own central axis at a certain angle, so that the material completes the angle adjustment and positioning, the product moves to the bottom of the suction pipe 60, the suction pipe 60 breaks the vacuum and assembles the material onto the product.

[0098] It should be noted that all the first adapter modules 31 in the present invention can work independently, so that the suction pipe 60 can independently take out materials and break vacuum.

[0099] It should also be noted that all the first drive mechanisms 50 in the present invention can work synchronously or independently, so that several suction tubes 60 can work synchronously or independently, and multiple materials can be assembled onto the product at one time, or the materials can be assembled onto the product separately in sequence.

[0100] The present invention further discloses a material suction and discharge method, which adopts the multi-position material suction mechanism and adopts the following steps:

[0101] Step 1: Connect the suction pipe 60 to the first channel A1 on the first adapter module 31;

[0102] Step 2: Connect the second channel A2 on the second adapter module 32 to the second air path B2 on the first adapter module 31; connect the third air path B3 on the second adapter module 32 to the external positive pressure device P2; and connect the first air path B1 on the first adapter module 31 to the external negative pressure device P1;

[0103] Step 3: Open the first air path B1 and close the second air path B2. Air passes through the suction head 64, the suction pipe 60, the first channel A1, and the first air path B1 in sequence to reach the external negative pressure device P1, creating a negative pressure state inside the suction pipe 60, and the suction pipe 60 sucks the material.

[0104] Step 4: The second and third air paths B2 and B3 are opened, and the first air path B1 is closed. The gas output by the external positive pressure device P2 passes through the third air path B3, the second channel A2, the second air path B2, and the first channel A1 in sequence to reach the suction pipe 60, creating a positive pressure state inside the suction pipe 60, breaking the vacuum inside the suction pipe 60 and allowing the sucked material to be released.

[0105] Step 5: The second air path B2 and the fourth air path B4 are opened, and the first air path B1 and the third air path B3 are closed. The atmosphere P0, the fourth air path B4, the second channel A2, the second air path B2, the first channel A1, and the suction pipe 60 are connected in sequence, so that the interior of the suction pipe 60 is in a normal pressure state.

[0106] Step 6: Repeat steps 3 to 5 to allow the suction pipe 60 to cycle through the suction and discharge of materials.

[0107] In summary, the present invention provides a plurality of first adapter modules 31 corresponding to the suction pipe 60 on the suction body 20, each of the first adapter modules 31 includes a first air path B1 and a second air path B2, and the first adapter module 31 is connected to the suction pipe 60 through the first channel A1. When the external negative pressure device P1, the first air path B1 and the first channel A1 are connected, a negative pressure state is formed inside the suction pipe 60, and the suction pipe 60 takes the material independently; when the external positive pressure device P2, the second air path B2 and the first channel A1 are connected, a positive pressure state is formed inside the suction pipe 60. In a positive pressure state, the suction pipe 60 breaks the vacuum independently, so it can be used in production scenarios that require independent material removal and independent vacuum breaking, and has a wide range of applications; at the same time, the present invention sets a second adapter module 32 to realize that the interior of the suction pipe 60 has three states of negative pressure, positive pressure and normal pressure, corresponding to the three production scenarios of suction, vacuum breaking and non-operation; a number of first drive mechanisms 50 and a third adapter module 41 are set to realize the independent lifting of the suction pipe 60; a rotating drive mechanism 42 is set to realize the synchronous rotation of a number of suction pipes 60, so as to realize the synchronous angle adjustment and positioning of the materials.

Therefore, any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical practice of the present invention are still within the scope of the technical solution of the present invention.
