[0078] Embodiment 8:

[0079] This embodiment provides an automated SMT placement machine adsorption device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the eight barrels 21 are all located between two fixed plates 18 and two fixed plates 19.

[0080] The structural stability of the eight barrels 21 is ensured.

[0081] It is worth noting that the hose 23 has a sufficient length and will not be folded or tightened, ensuring that the hose 23 will not hinder the normal operation of the barrel 21. The hose 23 involved in the utility model adopts the threaded metal hose with the product number SA-08 produced by Shanghai Xuxi Corrugated Pipe Manufacturing Co., Ltd. The hose 23 involved in the utility model is a prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to the structure and working principle of the hose 23.

[0082] Working principle: When this device is in use, the rectangular plate 1 is first fixed to the placement machine by several bolts, and then the personnel can start the servo motor 5 first. The output shaft of the servo motor 5 drives the threaded rod 4 to rotate. Under the action of the thread, the threaded rod 4 rotates to drive the U-shaped plate 3 to move forward and backward in the sliding groove 2. The forward and backward movement of the U-shaped plate 3 drives the electric slide rail 6 to move forward and backward. The forward and backward movement of the electric slide rail 6 will drive the sliding sleeve 7 to move forward and backward. The forward and backward movement of the sliding sleeve 7 will drive the hydraulic cylinder 8 to move forward and backward. At the same time, the electric slide rail 6 can be started, and the electric slide rail 6 will drive the sliding sleeve 7 to move left and right. The left and right movement of the sliding sleeve 7 will drive the hydraulic cylinder 8 to move left and right. The hydraulic cylinder 8 can be moved to the top of the product, and then the hydraulic cylinder 8 is started again. The output end of the hydraulic cylinder 8 drives the rectangular block 9 to move downward. The downward movement of the rectangular block 9 will drive the two fixed plates 18 and the two The two fixing plates 19 move downward, and the two fixing plates 18 and the two fixing plates 2 19 move downward, which will drive the eight round barrels 21 to move downward. The eight round barrels 21 move downward, which will respectively drive the eight round tubes 22 and the eight suction cups 24 to move downward until the bottom of the suction cup 24 contacts the product. At this time, the round tube 22 squeezes the spring 25 to shrink. Under the action of the rebound force of the spring 25, the suction cup 24 can be buffered to ensure that the suction cup 24 does not damage the product when it moves downward. Then, the vacuum pump 26 is started. The vacuum pump 26 can extract the air in the eight round tubes 22 and the eight suction cups 24 through the vacuum box 20 and the eight hoses 23, so that negative pressure is formed in the eight suction cups 24, so that the product is adsorbed on the bottom of the eight suction cups 24, so as to automatically adsorb the product and move the product to the position where the patch is required;

[0083] When the area of ​​the product to be patched is large, the servo motor 2 17 can be started before the product is adsorbed. The output shaft of the servo motor 2 17 will drive the elliptical block 2 16 and the elliptical block 1 13 to rotate. The rotation of the elliptical block 2 16 will squeeze the two moving plates 2 14, so that the two moving plates 2 14 move away from each other. At the same time, the two moving plates 2 14 move away from each other, which will pull the two tension springs 2 15 to extend. The two moving plates 2 14 move away from each other and also drive the two fixed plates 2 19 to move away from each other. The rotation of the elliptical block 13 will squeeze the two moving plates 11, so that the two moving plates 11 move away from each other. The two movable plates 11 moving away from each other will pull the two tension springs 12 to extend, and at the same time, the two movable plates 11 moving away from each other will also drive the two fixed plates 18 to move away from each other, the two fixed plates 19 moving away from each other and the two fixed plates 18 moving away from each other will respectively drive the two barrels 21 to move away from the position of the rectangular block 9, and the hose 23 will extend. At this time, the unfolded area of ​​the eight rectangular blocks 9 will become larger, thereby increasing the adsorption area of ​​the eight suction cups 24, ensuring that the personnel can adjust the adsorption area of ​​the eight suction cups 24 according to the size of the product, so as to ensure that products of different sizes can be adsorbed.
