技术领域Technical Field
本实用新型涉及真空吸附装置领域，特别是涉及一种密封性好的真空吸附装置。The utility model relates to the field of vacuum adsorption devices, in particular to a vacuum adsorption device with good sealing performance.
背景技术Background technique
近年来，真空吸附技术在工业自动化生产中的应用越来越广泛，真空吸附是利用真空发生装置产生真空压力为动力源，由真空吸盘吸附抓取物体从而达到移动物体，为产品的加工和组装服务，对任何具有较光滑表面的物体，特别是那些不适合于夹紧的物体，都可使用真空吸附来完成，真空吸附已广泛应用于电子电器生产、汽车制造、产品包装、板材输送等作业中，因为真空技术涉及很广的压力范围，没有一种单独的抽气设备可以把真空系统从大气压抽吸到高真空或超高真空的区域，虽然所有抽气设备的作用都是使气相中存在的气体分子数目降低，但各种设备均有其不同地获得真空的原理和方法。In recent years, vacuum adsorption technology has been increasingly used in industrial automation production. Vacuum adsorption uses the vacuum pressure generated by a vacuum generating device as a power source, and the vacuum suction cup adsorbs and grasps objects to move objects, serving the processing and assembly of products. Any object with a relatively smooth surface, especially those that are not suitable for clamping, can be completed by vacuum adsorption. Vacuum adsorption has been widely used in electronic and electrical production, automobile manufacturing, product packaging, sheet metal transportation and other operations. Because vacuum technology involves a wide range of pressures, there is no single vacuum device that can pump the vacuum system from atmospheric pressure to high vacuum or ultra-high vacuum areas. Although the function of all vacuum devices is to reduce the number of gas molecules in the gas phase, various devices have different principles and methods of obtaining vacuum.
中国专利公开号CN214827207U公开了一种密封性好的真空吸附装置，涉及真空吸气设备技术领域，包括固定支架、真空吸附装置和附件磨头，所述真空吸附装置的外壁与附件磨头的一侧固定连接，所述附件磨头的顶部与固定支架的底部固定连接，所述真空吸附装置包括真空外壳、压板和真空通气轴，所述真空外壳的外壁固定连接有骨架密封圈。本实用新型通过在真空通气轴和物体接触的一端增加转接头，转接头和真空通气轴可以拆卸，并且转接头的另一端增加了密封件，在对物体进行吸附时，密封件可以使真空通气轴达到更好的真空效果，更好地对物体进行吸附，在轴承的一侧增加骨架密封圈，轴承起到固定和旋转作用，骨架密封圈保证了真空外壳内的密封性，增强装置密封性和实用性。Chinese patent publication number CN214827207U discloses a vacuum adsorption device with good sealing performance, which relates to the technical field of vacuum suction equipment, including a fixed bracket, a vacuum adsorption device and an accessory grinding head, wherein the outer wall of the vacuum adsorption device is fixedly connected to one side of the accessory grinding head, and the top of the accessory grinding head is fixedly connected to the bottom of the fixed bracket. The vacuum adsorption device includes a vacuum shell, a pressure plate and a vacuum ventilation shaft, and the outer wall of the vacuum shell is fixedly connected with a skeleton sealing ring. The utility model adds an adapter to one end of the vacuum ventilation shaft that contacts the object, and the adapter and the vacuum ventilation shaft can be disassembled, and a sealing member is added to the other end of the adapter. When the object is adsorbed, the sealing member can enable the vacuum ventilation shaft to achieve a better vacuum effect and better adsorb the object. A skeleton sealing ring is added to one side of the bearing, and the bearing plays a role of fixing and rotating. The skeleton sealing ring ensures the sealing performance in the vacuum shell, and enhances the sealing performance and practicality of the device.
但是，现有技术中的真空吸附装置，一次只能吸附固定一个工件，无法同时对多个工具进行固定，且在使用时，所有的吸气孔均处于导通状态，若无工件吸附，则会导致持续漏气，影响装夹效果。However, the vacuum adsorption device in the prior art can only adsorb and fix one workpiece at a time and cannot fix multiple tools at the same time. In addition, when in use, all the suction holes are in a conducting state. If there is no workpiece adsorption, it will cause continuous leakage, affecting the clamping effect.

When the workpiece is placed on the table 2, the lower end of the workpiece is pressed on the push rod 4, so that the push rod 4 moves downward, and the push rod 4 pushes the first blocking block 602 to move downward, thereby exposing the connection between the suction connecting pipe 7 and the first sliding pipe 601, so that the gas in the adsorption tube 3 can be sucked away by the adsorption mechanism 5, and when the workpiece After being fully pressed on the upper end of the adsorption tube 3, the adsorption mechanism 5 will extract all the air in the adsorption tube 3 through the suction connecting tube 7, generating negative pressure, firmly sucking the workpiece onto the adsorption tube 3, fixing the workpiece, and multiple adsorption tubes 3 can adsorb the workpiece at the same time, and can adsorb multiple workpieces at the same time; and, in the unused part, the first blocking block 602 is still in the state of blocking the first sliding tube 601, thereby preventing gas circulation; when the workpiece needs to be removed, the valve on the suction pipe 502 is closed, and the valve on the blowing pipe 503 is opened, so that the gas is blown into the adsorption tube 3 through the blowing mechanism 8, so that the pressure in the adsorption tube 3 is balanced, so that the workpiece can be removed, and the first elastic member 603 pushes the first blocking block 602 to reset, and continues to block the suction connecting pipe 7.
实施例二Embodiment 2
如图1-图3所示，本实用新型提出的一种密封性好的真空吸附装置，相较于实施例一，本实施例中的吹气机构8包括第二封堵管801、第二封堵块802、第二弹性件803和连通管804；连通管804的两端分别与吸附管3和第二封堵管801连接；第二封堵块802滑动设置在第二封堵管801内；第二弹性件803设置在第二封堵管801内，第二弹性件803的两端分别与第二封堵管801和第二封堵块802连接；第二封堵块802与连通管804密封连接；吸附机构5的输出端与第二封堵管801的上端连通。吸附机构5包括负压泵501、吸气管502和吹气管503；负压泵501设置在工作台1上；负压泵501包括吸气端和排气端；吸气管与吸气管502连通；吸气管502与吸气连接管7连通；排气端与吹气管503连通；吹气管503与吹气连接管9连通。As shown in Figures 1 to 3, the utility model proposes a vacuum adsorption device with good sealing performance. Compared with Example 1, the blowing mechanism 8 in this embodiment includes a second sealing tube 801, a second sealing block 802, a second elastic member 803 and a connecting tube 804; the two ends of the connecting tube 804 are respectively connected to the adsorption tube 3 and the second sealing tube 801; the second sealing block 802 is slidably arranged in the second sealing tube 801; the second elastic member 803 is arranged in the second sealing tube 801, and the two ends of the second elastic member 803 are respectively connected to the second sealing tube 801 and the second sealing block 802; the second sealing block 802 is sealed and connected to the connecting tube 804; the output end of the adsorption mechanism 5 is connected to the upper end of the second sealing tube 801. The adsorption mechanism 5 includes a negative pressure pump 501, an air suction pipe 502 and an air blowing pipe 503; the negative pressure pump 501 is arranged on the workbench 1; the negative pressure pump 501 includes an air suction end and an air exhaust end; the air suction pipe is connected to the air suction pipe 502; the air suction pipe 502 is connected to the air suction connecting pipe 7; the exhaust end is connected to the air blowing pipe 503; the air blowing pipe 503 is connected to the air blowing connecting pipe 9.

Since the transported gas is located above the second blocking block 802, the air pressure in the upper part of the second blocking tube 801 is greater than the air pressure in the lower part, thereby pushing the second blocking block 802 to move and compressing the second elastic member 803, so that the second blocking block 802 exposes the connecting tube 804, so that the gas can be injected into the adsorption tube 3, and the negative pressure in the adsorption tube 3 is released, so that the workpiece can be removed.
