In other words, each air chamber 110 of the suction unit 100 is connected to one air chamber. The valve 120, that is, the pumping pump, has the same contribution to the pumping volume and the pressure difference of each air chamber 110.

It is worth mentioning that, in order to make the suction force at the suction hole 210 greater than the suction force at the point where the air valve 120 is connected to the suction pump, the sum of the cross-sectional areas of the two suction holes 210 in this embodiment is smaller than that of the air valve connected to the corresponding air chamber 110 The cross-sectional area of the pores of 120. To be precise, for each air chamber 110 in the suction part 100, as long as the total cross-sectional area of the suction hole 210 connected to the air chamber 110 is greater than the cross-sectional area of the air valve 120 connected to the air chamber 110, according to the continuous equation, The gas flow rate of the suction hole 210 will be greater than the gas flow rate of the gas valve 120. Therefore, the gas flow rate of the gas valve 120 can be adjusted to ensure the lowest gas flow rate of the suction hole 210 so that the suction force at the suction hole 210 is greater than the setting The goal.

Between the air chamber 310 and the second connecting air chamber 320. Specifically, taking the above-mentioned air chamber 110 and the two suction holes 210 as an example, one of the first connecting air chambers 310 is connected to the second air passages 330 through the two air passages 330 of the air passages 330. Connect the two second connecting air chambers 320 in the air chamber 320. In other words, the first connecting air chamber 310 is connected to two different second connecting air chambers 320 through two sub-air ducts 330, and is connected to the second connecting air chamber 320 The situation of the first connecting air chamber 310 is similar, the above-mentioned first connecting air chamber 310 is also connected to the other connecting air chamber 310 of these first connecting air chambers 310 to the air chamber 110, and the above-mentioned two suction holes 210 are connected to These two second connection air chambers 320. That is to say, the air chamber 110 on the right side in FIG. 5 is connected with two first connecting air chambers 310, five sub-air ducts 330, five second connecting air chambers 320, and eight suction holes 210, which represent the air distribution part.

On the other hand, when the adhesive tape is to be adsorbed to the suction part 200, the suction hole 210 located at the end of the air-chamber suction module 1 will require a relatively large suction force to peel the adhesive tape from the adhered object. . Therefore, in this embodiment, the above-mentioned air chamber 110 is disposed at one end (for example, the right end) of the suction part 100, and the number of suction holes 210 connected to this air chamber 110 is less than that of the suction holes 210 connected to other air chambers individually. Quantity. As shown in Figures 4 and 5, the number of suction holes 210 connected to the air chamber 110 on the right is eight, while the number of suction holes 210 connected to the air chamber 110 on the left is 36. An air valve 120 is connected. Therefore, at the same pumping speed, the suction holes 210 corresponding to the air chambers 110 with a smaller number of connected suction holes 210 have a larger suction force. Through this configuration, the air-chamber suction module 1 can peel off the adhesive tape at the end with a strong suction force, and maintain the suction force of the suction holes 210 in other parts not to exceed the predetermined target.

When the two are combined, the rivets can be Locking members such as screws or screws are inserted through the locking hole 140 and the locking hole 340 to combine the air suction part 100 and the air distribution part 300. In addition, in order to firmly combine the suction part 100 and the gas distribution part 300 and form an airtight, the suction part 100 is formed with a flange 150 on the side connecting the gas distribution part 300, and the flange 150 is opposite to the The surface protrudes and surrounds the air chamber 110; on the other hand, the air distribution part 300 is formed with a groove 350 on the side connected to the suction part 100, wherein the groove 350 is recessed relative to the surface and surrounds the air chamber 110. Two different first connecting air chambers 310, when the suction part 100 is combined with the air distribution part 300, the flange 150 will be embedded in the groove 350. Through such a configuration, even if airtight parts such as O-rings are not used to achieve airtightness, the air chamber suction module 1 can still prevent external air from entering the air chamber 110 through the interference of the flange 150 and the groove 350. And in each pipeline of the air distribution part 300.

It is worth mentioning that, as shown in FIGS. 5 and 7, one end of the air distribution channels 330 is connected to the side of the first connecting air chamber 310 opposite to the air chamber 110, and the other end of the air distribution channels 330 is connected to the second air chamber.

In other words, the part of the air dividing duct 330 connected to the first connecting air chamber 310 and the second connecting air chamber 320 is a surface away from the air chamber 110 and the suction hole 210. Through this configuration, not only can the sub-airway 330 communicate with the first connecting air room 310 and the second connecting air room 320 in a shorter straight path, but also the gas drawn from the suction hole 210 to the second connecting air room 320 and the gas from the air-separating channel 330 The gas pumped to the first connecting air chamber 310 can be uniformly convectively mixed and then drawn out by the sub-airway 330 and the air valve 120, so that it can further ensure that the suction holes 210 connected to the same second connecting air chamber 320 and the same The suction force of the first connecting air chamber 310 of one air chamber 110 is the same, so as to maintain the stability when sucking objects.
