Description

具有真空吸盘的真空吸附机器人Vacuum adsorption robot with vacuum chuck 技术领域Technical field

本发明涉及一种具有真空吸附部件的机器人，尤其是一种家庭清洁机器人，具体涉及一种具有真空吸盘的真空吸附机器人。The invention relates to a robot with a vacuum adsorption component, in particular to a household cleaning robot, in particular to a vacuum adsorption robot with a vacuum suction cup.

背景技术Background technique

随着人们生活水平的改善，越来越多的自动化家庭作业机械进入了日常的生活家庭，尤其是自动吸尘器、家庭清洁机器人等家庭用自动清理机器越来越受到人们的广泛欢迎。With the improvement of people's living standards, more and more automated homework machines have entered the daily life of the family, especially automatic cleaning machines such as automatic vacuum cleaners and household cleaning robots have become more and more popular.

现有的此类机器在壁面吸附时通常是通过真空吸盘提供吸附力，将机器本体吸附在墙壁、玻璃、柜面或类似结构上。在机器完成工作后，操作者需要取下机器，由于此时吸盘内仍然保持真空状态(即吸盘的盘体与吸附面构成了真空环境)，为了取下机器，要么是强行取下机器，这种方法不但费时费力而且有可能损坏被吸附面或机器本身；或者是采用泄气方式，即在真空吸盘上设置独立的泄气阀，取下机器时首先打开泄气阀开关，待空气进入到真空室后取下机器。本申请的申请人在先专利申请201220496078中就公开了一种类似的技术方案。然而此方法操作繁琐，需要操作者分别握住机器和打开泄气阀开关，如果动作不够熟练在打开泄气阀后没有握住机器，机器存在跌落损坏的危险。Existing such machines, when adsorbed on the wall, typically provide suction through a vacuum chuck to attract the body of the machine to walls, glass, countertops or the like. After the machine finishes the work, the operator needs to remove the machine. At this time, the vacuum is still maintained in the suction cup (ie, the disk body and the suction surface of the suction cup constitute a vacuum environment), in order to remove the machine, the machine is forcibly removed. The method is not only time-consuming and laborious, but also may damage the adsorbed surface or the machine itself; or use a deflation method, that is, an independent venting valve is provided on the vacuum chuck, and the vent valve is first opened when the machine is removed, after the air enters the vacuum chamber. Remove the machine. A similar technical solution is disclosed in the applicant's prior patent application 201220496078. However, this method is cumbersome to operate, requiring the operator to hold the machine separately and open the vent valve switch. If the action is not skilled enough, the machine does not hold the machine after opening the vent valve, and the machine is in danger of falling and damage.

发明内容Summary of the invention

针对现有技术的缺陷，本发明公开了一种具有触发泄气开关的真空吸附机器人，通过对结构的改进能够使得通过机器把手提起力度来识别操作者的意图，以触发开关使真空吸盘的真空室自动泄气，从而便于操作者轻松、安全、快捷的取下机器。In view of the deficiencies of the prior art, the present invention discloses a vacuum adsorption robot having a triggering venting switch, which can improve the structure and can lift the force by the handle of the machine to recognize the operator's intention to trigger the vacuum chamber of the vacuum chuck.

在本发明中，可以采用任何在力学上可行的结构方式作为泄气机构、泄气开关，机械式连接结构、电气化连接结构或磁性连接结构等均可用于本发明。 In the present invention, any mechanically feasible structural means can be employed as the deflation mechanism, the deflation switch, the mechanical connection structure, the electrified connection structure or the magnetic connection structure, etc., which can be used in the present invention.

当采用机械式结构时，所述泄气开关为位于把手底部的凸起，所述泄气机构为设在真空吸盘上与所述凸起相对应连接的泄气孔。When the mechanical structure is adopted, the air release switch is a protrusion located at the bottom of the handle, and the air release mechanism is a air leakage hole provided on the vacuum suction cup corresponding to the protrusion.

通过上述结构，通过操作把手凸起脱离或堵住泄气孔即可完成真空室的开放与密封，从而使得吸盘解除与被吸附面的吸附或保持吸附状态。With the above structure, the opening and sealing of the vacuum chamber can be completed by operating the handle protrusion to disengage or block the vent hole, so that the suction cup is released from the adsorption or the adsorption state of the adsorbed surface.

为了便于把手用力均匀，尽可能提高操作的准确程度，所述凸起位于机体底部中心位置，所述泄气孔位于真空吸盘顶部中心。In order to facilitate the uniform force of the handle and to improve the accuracy of the operation as much as possible, the protrusion is located at the center of the bottom of the body, and the vent hole is located at the center of the top of the vacuum chuck.

With the above structure, the automatic deflation valve can be activated or deactivated by the touch of the deflated switch when the handle is lifted, and the vacuum suction cup is deflated or adsorbed.

进一步的，为了在把手释放后使真空吸盘重新保持密封状态，把手与机体间设有复位单元。Further, in order to re-seal the vacuum chuck after the handle is released, a reset unit is disposed between the handle and the body.

本领域技术人员可以理解，上述的复位单元指的是能够拉动把手重新朝向真空吸盘方向运动的装置，在机械力学和电磁学领域具有多种力学方式可满足此需求，例如弹力、电磁力等。It will be understood by those skilled in the art that the above-mentioned resetting unit refers to a device capable of pulling the handle to re-orient toward the vacuum chuck, and various mechanical means in the fields of mechanics and electromagnetism can satisfy such requirements, such as elastic force, electromagnetic force and the like.

优选的，考虑到应用成本和结构的简便，所述复位单元为弹簧，弹簧的一端连接把手底部，另一端连接机体顶部。Preferably, considering the application cost and the simplicity of the structure, the reset unit is a spring, one end of the spring is connected to the bottom of the handle, and the other end is connected to the top of the body.

在上述结构下，通过弹簧弹力的作用即可实现自动复位操作。Under the above structure, the automatic reset operation can be realized by the action of the spring force.

更优选的，为了保证把手各角度以均匀速度复位，所述弹簧为多组，均匀分布在把手与机体间。More preferably, in order to ensure that the angles of the handle are reset at a uniform speed, the springs are in multiple groups and are evenly distributed between the handle and the body.

通过上述改进，本发明的真空吸附机器人可以通过用户提起把手的动作触发真空吸盘泄气，操作方便，并且有效减少了机器跌落损坏的概率。Through the above improvement, the vacuum adsorption robot of the present invention can trigger the vacuum suction cup to deflate by the action of lifting the handle by the user, is convenient to operate, and effectively reduces the probability of the machine falling and being damaged.

实施例一Embodiment 1

图1为本发明的具有机械式触发泄气开关的真空吸附机器人结构示意图。参考图 1所示，本发明所提供的真空吸附机器人包括机体1以及设置在机体底部的真空吸盘2，机体顶部还设有用于提起机器的把手11，真空吸盘2在工作时与被吸附面构成真空室，其中在真空吸盘顶部设有泄气孔21，把手底部设有与泄气孔21对应的凸起12。1 is a schematic view showing the structure of a vacuum adsorption robot having a mechanical trigger gas vent switch according to the present invention. Reference map As shown in Figure 1, the vacuum adsorption robot provided by the present invention comprises a body 1 and a vacuum chuck 2 disposed at the bottom of the body. The top of the body is further provided with a handle 11 for lifting the machine. The vacuum cup 2 forms a vacuum chamber with the adsorbed surface during operation. There is a vent hole 21 at the top of the vacuum chuck, and a protrusion 12 corresponding to the vent hole 21 is provided at the bottom of the handle.

其工作过程如下：正常工作时，凸起将泄气孔堵住，确保真空吸盘与被吸附面之间处于密封状态，当沿着垂直于吸附表面的方向提起把手时，凸起脱离泄气孔，使真空室与大气相通，操作者可以轻松将机器取下。The working process is as follows: during normal operation, the protrusion blocks the vent hole to ensure a sealed state between the vacuum suction cup and the adsorbed surface, and when the handle is lifted in a direction perpendicular to the adsorption surface, the protrusion is separated from the vent hole, so that The vacuum chamber is open to the atmosphere and the operator can easily remove the machine.

实施例二Embodiment 2

图2为本发明的具有电气触发泄气开关的真空吸附机器人结构示意图。参考图2所示，机体1上设有与真空吸盘2相连的自动泄气阀22，把手对应位置设有泄气开关13。2 is a schematic view showing the structure of a vacuum adsorption robot having an electric trigger air release switch according to the present invention.

The automatic venting valve can be a solenoid valve of the prior art.

进一步的，参考图1、图2所示，把手与机体间还设有复位弹簧3，把手被释放后在弹簧弹力作用下使真空吸盘重新保持密封状态。在图1所示结构中，弹力使得凸起重新堵住泄气孔；在图2所示结构中，弹力使得泄气开关复位，自动泄气阀关闭。Further, referring to FIG. 1 and FIG. 2, a return spring 3 is further disposed between the handle and the body, and the vacuum suction cup is resealed under the spring force after the handle is released. In the configuration shown in Figure 1, the spring force causes the projection to re-block the venting opening; in the configuration shown in Figure 2, the spring force causes the venting switch to reset and the automatic venting valve to close.

复位弹簧3张力的大小可以影响使自动泄气阀打开的把手提起力F的大小。在上述实施中,尽管没有明确指出，但是本领域技术人员可以理解诸如磁性结构也可完成上述过程，例如两块相吸的磁石代替上述机械式结构也可实现其功能，此处不予赘述。 The magnitude of the tension of the return spring 3 can affect the amount of the handle lifting force F that causes the automatic vent valve to open. In the above implementation, although not explicitly stated, those skilled in the art can understand that the above process can also be completed by a magnetic structure, for example, two attracting magnets can realize the functions instead of the above-mentioned mechanical structure, and details are not described herein.
