In the embodiment, the raw material profile of the curtain wall is an aluminum profile, a five-axis saw is adopted as a sawing mechanism in the cutting unit 4, and a numerical control three-axis machining center is adopted in the milling unit 5. The first milling station 11 and the second milling station 12 are each provided with a milling unit 5 for processing two opposite faces of the raw material profile, and two milling stations are provided for improving the processing efficiency.

When the aluminum profile clamping device works, the manipulator at the corresponding position moves on the sliding rail 6 to clamp and convey the aluminum profile to the corresponding position for placement and work. The material taking manipulator 1 moves back and forth between the material area 7 and the material feeding station 8 along the sliding rail 6, and conveys the material section bar of the material area 7 to the material feeding station 8; the carrying manipulator 2 moves along the slide rail 6 at the cutting station 9, the first milling station 11, the second milling station 12 and the inspection zone 10; the palletizing robot 3 moves along the slide rail 6 in the inspection zone 10, the second milling station 12 and the palletizing zone 13. The material taking manipulator 1, the conveying manipulator 2 and the stacking manipulator 3 are provided with adjustable clamping ends so as to be suitable for clamping aluminum profiles with different sizes; the cutting unit and the milling unit are provided with adjustable compacting parts so as to be suitable for compacting aluminum profiles with different sizes, and the cutting unit and the milling unit can complete the cutting process and the milling process.

The intelligent control terminal is used for intelligent control of the whole production line, and the sizes and end surface configurations of the sectional materials required by different positions of the curtain wall are different; based on this, the raw material profile correspondingly has a plurality of different end configurations; and the processing information of each raw material profile (i.e. the processing information from the raw material profile to the corresponding finished profile) is different. As an example, in this production line, the processing information of the raw material profile includes two kinds of: (1) cutting only; and (2) cutting and then performing face milling treatment. Processing information of each raw material profile is preset in the intelligent control terminal, and as an example, the processing information can be preset in the intelligent control terminal in a three-dimensional processing model mode. Each raw material profile is provided with an image mark (such as a two-dimensional code) for identity recognition; the intelligent control terminal automatically acquires corresponding processing information by carrying out image recognition on the raw material profile so as to control the cutting unit 4 and the milling unit 5 to process the raw material profile, and further obtain the required finished product profile. As an example, an MES manufacturing execution system is arranged in the intelligent control terminal, so that control over a production line is realized.

In addition, a plurality of blanking areas can be arranged between the cutting station 9 and the second milling station 12 along the production line and used for storing finished profiles in different stages; a blanking zone is provided between the cutting station 9 and the first milling station 11 for the storage of profiles having only a cutting process; a blanking area is arranged between the first milling station 11 and the second milling station 12 and is used for storing the profile which is only milled on one side; and conveying the section bars in the blanking area to a set position by an AGV trolley for storage.

The working flow of the intelligent production line is as follows: the raw material sectional materials are stacked on a tray of the raw material area 7 according to a set sequence, and the material taking manipulator 1 takes materials from the raw material area 7 under the control of the intelligent control terminal and conveys the raw material sectional materials to the feeding station 8; the image recognition module arranged between the raw material area 7 and the feeding station 8 performs image recognition on the raw material profile clamped by the current material taking manipulator 1 and sends the raw material profile to the intelligent control terminal, and the intelligent control terminal calls processing information of the current raw material profile so as to control the cutting unit 4 and the milling unit 5 to process. The material taking manipulator 1 returns the material section to the material feeding area 7 to take out the next material section after placing the material section to the material feeding station 8, and the material taking manipulator repeatedly moves.

On the cutting station 9, the cutting unit 4 saw cuts the raw material section bar into a set length according to the processing information given by the intelligent control terminal, and if the raw material section bar only has a cutting procedure, the conveying manipulator 2 sends the saw cut section bar to a blanking area between the cutting station 9 and the first milling station 11 for storage; if the raw material profile also has a milling process, the carrying manipulator 2 carries the sawn profile to the first milling station 11; milling the front surface (two opposite surfaces of the profile to be milled are respectively a front surface and a back surface) of the profile by a milling unit 5 at a first milling station 11 according to processing information given by an intelligent control terminal; if the profile needs secondary milling, the conveying manipulator 2 turns the profile 90 degrees or 180 degrees to enable the back surface of the profile to face the milling unit and then conveys the profile to the second milling station 12, and the milling unit 5 at the second milling station 12 mills the back surface of the aluminum profile; after the secondary milling is completed, the stacking manipulator 3 sends the milled section bars to the stacking area 13 for placement. If the profile does not need secondary milling, the stacking manipulator 3 directly sends the milled profile to a stacking area or a nearby blanking area.

In order to realize control of the processing performance of the profile, the processed profile is inspected at regular intervals, including the cut profile, the profile subjected to the first milling and the profile subjected to the second milling are inspected at regular intervals; specific: the intelligent control terminal controls the conveying manipulator 2 to periodically place the cut section bar, the section bar after the first milling and the section bar after the second milling into a set checking area 10 for checking (for example, whether the length of the section bar meets the requirements or not is judged through laser ranging, whether the milling end face meets the requirements or not is judged through image recognition, and the like).

As an example, to further improve the processing efficiency, the intelligent control terminal can sort the processing sequence of each raw material profile according to the processing information of all raw material profiles in the current batch, so as to effectively utilize the processing time; and stacking the raw material sections in the raw material area according to the processing sequence given by the intelligent control terminal. The method comprises the following steps: according to the processing time of each raw material section bar, the processing sequence of each raw material section bar is ordered, for example, because the milling process is relatively longer than the cutting process, especially the milling process with more complicated end face structure, in order to improve the processing efficiency of the whole production line, when milling, the cutting station 9 processes the raw material section bar which only needs to be subjected to the cutting process, and after the cutting process, the finished product section bar is directly placed in a blanking area by the conveying manipulator 2 for storage. Therefore, when milling is carried out at two milling stations, the cutting unit 4 is not stopped, and the cutting operation of a plurality of raw material sections is finished at the same time; and because the intelligent control terminal pre-stores the processing information of all raw material sectional materials, the processing sequences of all raw material sectional materials can be automatically ordered, so that the reasonable distribution of the processing time of each station is ensured, and the processing efficiency is improved to the greatest extent.

As an example, below the cutting station 9, the first milling station 11 and the second milling station 12 there is provided a waste collection box for the collection of the waste produced by the corresponding working process; the waste collection box is periodically conveyed to a waste area by an automatic conveying device (such as a conveying belt controlled by an intelligent control terminal) for discharging, and then returns to the original position for continuously collecting waste; thereby ensuring the intelligent and continuous production of the whole production line.

A clamp assembly 154 is rotatably disposed at a lower end of the upright 152; specifically, the clamping assembly 154 is pinned to the lower end of the upright post 152, and the axial direction of the pin shaft is along the X direction; the clamping assembly 154 is used for clamping the profile; a rotary drive 155 is mounted to the upright 152 for driving rotation of the clamp assembly 154 about its pin connected to the upright 152. In this example, the clamp assembly 152 is capable of 0 ° to 180 ° of angular rotation under the drive of the rotary drive 154. The vertical driving member 153 and the rotary driving member 155 are controlled by an intelligent control terminal.

As shown in fig. 4, to accommodate clamping of aluminum profiles of different sizes, the clamping assembly 154 includes: a fixing rod 1541 and two groups of clamping units fixed on the fixing rod 1541, wherein the fixing rod 1541 is installed on a pin seat at the lower end of the upright post 152; the clamping unit includes: a clamp mount 1542, a jaw a1543, a jaw B1544, a drive member, and a stop member 1546.
