The pressure inside the negative pressure adsorption chamber is reduced, forming a stable negative pressure environment, ensuring that the gauze will not fall off or shift during the transportation process. Compared with the traditional mechanical clamping method, the physical damage to the gauze is reduced and the integrity of the gauze is protected; (3) The microneedle design in the present invention can pass through the adsorption breathable mesh plate during the gauze adsorption process to slightly puncture and fix the gauze. The size and angle of the microneedle are precisely designed to prevent the mesh from shifting during the adsorption process without causing damage to the mesh. When the mesh needs to be released, the microneedle is raised and lowered by an electromagnet to achieve precise release of the mesh. This method improves the reliability and safety of mesh handling.

[0022] An adsorption air-permeable mesh plate 125 is fixed to the bottom of the negative pressure adsorption chamber 122, and a plurality of densely distributed air holes are provided on the adsorption air-permeable mesh plate 125, wherein the microneedles 129 pass through the adsorption air-permeable mesh plate 125, and the microneedles 129 slide and cooperate with the adsorption air-permeable mesh plate 125.

An air baffle 103 is fixedly sleeved on the air shield 104 and the air collecting cover 110 to prevent the air flow from flowing toward the gauze.

[0024] The working principle of the needle puncture suction cup device for a single-layer gauze disclosed in the present invention is as follows: the device is installed as a whole on a mechanical arm, and it is controlled to move toward the gauze. The gauze is generally stored in stacks. In order to prevent the microneedles 129 from passing through two layers of gauze, the gauze needs to be layered (it should be noted that, for the sake of ease of description, the microneedles 129 shown in the figure are not in actual proportion). The arched friction roller 120 is brought into contact with the gauze, and then the mechanical arm needs to be urgently controlled to move toward the gauze (the mechanical arm is fixed to the negative pressure adsorption chamber 122, or connected to a fixed component of the negative pressure adsorption chamber 122). At this time, the arched friction roller 120 cannot continue to move, and then the arched friction roller guide slide bar 118 will move relative to the sliding horizontal plate 113. At this time, the arched friction roller return spring 119 is compressed, and the gearbox 115 will move relative to the fixed rack 114. The mobile gear 117 will roll on the fixed rack 114. The rotation of the fixed rack 114 will drive the input end of the gearbox 115 to rotate, and the output end of the gearbox 115 will drive the arched friction roller 120 to rotate through the transmission belt 116. At this time, the rotation direction of the two arched friction rollers 120 is On the contrary, they are all facing inward, that is to say, the rotation tangent directions of the contact surfaces of the two arched friction rollers 120 and the gauze are opposite. At this time, the gauze is driven to arch by the friction of the arched friction rollers 120 on the gauze, so that the arched part contacts the adsorption breathable mesh plate 125, and then the booster air wheel 108 is started. The booster air wheel 108 bulges into the booster spray booth 105 through the booster air pipe 106, and then the high-pressure gas inside the booster spray booth 105 is ejected through the air nozzle 109. The purpose of the air nozzle 109 is to accelerate the flow rate of the ejected gas. The ejected high-speed airflow will enter the interior of the guide air duct 101 through the air collecting hood 110. During this process, the internal pressure of the air flowing between the air nozzle 109 and the air collecting hood 110 will decrease (the pressure is low where the flow rate is fast), which will cause the relatively static air around to flow toward the low-pressure direction. At this time, more air will enter the guide air duct 101, including the air at the axis of the pressurized paint booth 105 and the air around the air nozzle 109 and the air collecting hood 110. The air entering the guide air duct 101 will enter the return pipe 111 through the three-way pipe 102, and then flow back to the air shield 104. Since the air shield 104 is arranged above the pressurized paint booth 105 and the pressurized air duct 106, this part of the air will be accelerated by the pressurized paint booth 105 again and flow back into the guide air duct 101. The air flowing inside the three-way pipe 102 will cause the pressure at the connection between the three-way pipe 102 and the negative pressure adsorption chamber 122 to decrease (perpendicular to the flow velocity direction), thereby causing the pressure inside the negative pressure adsorption chamber 122 to decrease. At this time, the gauze in contact with the lower surface of the adsorption air-permeable mesh plate 125 will be adsorbed on the lower surface of the adsorption air-permeable mesh plate 125 and hooked by the microneedles 129 to prevent separation from the adsorption air-permeable mesh plate 125. At this time, the gauze can be transferred or the required operation can be performed.When separation is required, the booster wheel 108 is stopped and the electromagnet 124 is started at the same time. The electromagnet 124 generates magnetic force to attract and drive the adsorption magnetic plate 128, which drives the adsorption magnetic plate 128 to drive the microneedle support frame 127 to move, and the microneedle support frame 127 drives the microneedle 129 to separate from the gauze. Under the action of gravity, the gauze will be separated from the lower surface of the adsorption breathable mesh plate 125. When the electromagnet 124 loses power, the microneedle support frame 127 and the microneedle 129 will be reset under the elastic force of the microneedle reset spring 133. Then grab the next layer of gauze. For example. Figure 6 As shown, the main dimensions of the microneedle 129 are designed as the needle tip engagement width D1, the needle tip engagement height D2, the needle tip angle α, the needle tip width L2 of the microneedle 129, and the overall width L1. The needle tip engagement width D1 is less than 2D, where D is the yarn mesh wire diameter, and the needle tip engagement height D1 is less than 1.5D. The needle tip angle is α, and α is less than 45°. The needle tip width L2 of the microneedle 129 should be greater than the yarn mesh aperture L+2D. The overall width L1 is 2L~3L.
