[0029] A plurality of vacuum suction chambers 4341 and a layer of heat absorption chamber 4342 are arranged in the adsorption plate 434, wherein the vacuum suction chambers 4341 are arranged corresponding to the middle part of the heat absorption chamber 4342, each vacuum suction chamber 4341 is connected with a suction channel 4343 at the bottom, the suction channel 4343 is connected with a suction pipe 4344, the inside of the heat absorption chamber 4342 is a cavity 4345, the outside of the cavity 4345 is a heat exchange layer 4346 and is communicated with an inlet 4347 and an outlet 4348.

[0032] The specific implementation method is as follows:

[0033] S1, each component to the initial state, before cutting, the control module drives the lifting cylinder 31 to lift to the highest position, the rotating motor 33 is in the stop state, the scraper assembly 5 is located at the highest position, the control positioning cylinder 41 pushes the workpiece adsorption assembly 43 as a whole to the inlet, drives the rotator 432, and turns the adsorption surface of the adsorption plate 434 to the inlet;

[0034] S2, feeding, starting the air extractor and the refrigerator connected with the adsorption plate 434, extracting the gas in the vacuum suction chamber 4341, and conveying the cold air to the cavity 4345 in the heat absorption chamber 4342. After the external feeding mechanism pushes the workpiece to the adsorption plate 434, a temporary vacuum state is formed in the vacuum suction chamber 4341, and a strong suction force is generated to adsorb the workpiece. At this time, the control module will drive the rotator 432 to rotate the adsorption surface of the adsorption plate 434 by 180°, and turn to the circular saw mechanism 3;

[0035] S3, positioning, the control module drives the positioning cylinder 41 to pull the workpiece adsorption assembly 43 as a whole to the direction of the circular saw mechanism 3 according to the required length to be cut off, and judges whether there is an obstacle through the signal feedback by the infrared detection module 435;

[0036] S4, cutting, after the workpiece is positioned, the control module starts the rotating motor 33, drives the lifting cylinder 31 to slowly pull down, so that the saw blade 34 starts to contact the workpiece and cut, and when it is pulled down to the lowest point, the workpiece cutting is completed;

[0037] S5, after cutting, the control module stops the rotary motor 33 and the external connection air extractor, and releases the vacuum state in the vacuum suction chamber 4341, so that the adsorbed workpiece falls off, at the same time, the circular saw mechanism 3 is reset to the initial state, and the scraper assembly 5 is lowered, so that the scraper 52 scrapes the front and rear surfaces of the saw blade 34, and whether the scraping is complete is judged through the signal feedback of the infrared detection module 435.

[0038] S6, the falling workpiece enters the recycling trolley 6 through the gap on the workbench 2 for unified recycling.

[0039] Specifically, the function of the cold air transported into the cavity 4345 of the heat absorption chamber 4342 in S2 is to absorb the large amount of heat generated during cutting of the workpiece. For metal workpieces, if the attached heat is too much, local deformation may occur. The heat absorption effect of the heat absorption chamber 4342 can effectively reduce the occurrence of such phenomenon, improve the cutting quality, and timely heat absorption can also avoid damage to the vacuum suction chamber 4341 caused by high temperature.

[0040] The main function of the infrared detection module 435 in S3 is to judge whether there is an obstacle between the circular saw mechanism 3 and the positioning mechanism 4 to ensure that the workpiece will not be blocked during movement. The length of the positioning cylinder 41 is as follows: the circular saw mechanism 3 only moves up and down, and does not affect the distance between the circular saw mechanism 3 and the positioning mechanism 4. The distance between the adsorption plate 434 and the surface where the saw blade 34 is located in the initial state is D, which is also the maximum distance. Assuming that the length of the workpiece is L and the length to be cut is d, the distance between the adsorption plate 434 and the surface where the saw blade 34 is located should satisfy (L-d), that is, the distance to be moved is D-(L-d).

[0041] The way that the infrared detection module 435 judges whether the scraping is complete in S4 is as follows: the distance between the adsorption plate 434 and the surface where the saw blade 34 is located in S3 is (L-d) during cutting. If the infrared detection module 435 detects that the distance of the obstacle in front is less than (L-d), it can be determined that there is a workpiece residue on the saw blade 34.
