Description

Technical Field

[0001] The utility model relates to the technical field of vacuum adsorption devices, in particular to a quick release mechanism for vacuum adsorption devices. Background Art

[0002] In modern industry, with the demand for zero-emission development of industrial automation and environmental protection requirements, coupled with the development of new materials and new technologies, electric technology has entered a climax of development. As a green energy, electric technology will bring great changes to human society. In line with the current trend of international scientific and technological development, taking electric technology as the entry point for the automation industry is not only a choice to achieve leapfrog development of the automation industry, but also an important choice to achieve sustainable development.

[0003] The main components of the electric vacuum suction device include a vacuum pump and suction cups of various shapes. It has an electric motor that runs at high speed after power is turned on, forming an instant vacuum inside. The internal air pressure is much lower than the external air pressure. Under the effect of this air pressure difference, the suction cup can adsorb various products. Normally, the device can complete adsorption and release after vacuum is broken after power is turned on. However, if the device encounters an emergency such as a sudden power outage or communication failure, the adsorbed product will be unable to be detached in a short time. Therefore, it is necessary to design a reliable manual quick release mechanism. Utility Model Content

[0004] Based on the above description, the utility model provides a quick release mechanism for a vacuum adsorption device to solve the problem that the vacuum adsorption device is difficult to release quickly in an emergency situation.

[0009] When the elastic element stretches, the blocking member seals the operation port; when the elastic element contracts, the blocking member opens the operation port.

[0010] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects: when the vacuum adsorption device is in a vacuum adsorption state, the vacuum pipeline is in a negative pressure state close to vacuum.

When it is necessary to quickly release the vacuum adsorption state (destroy the vacuum degree), the sealing member is pushed from the operating port. Due to the pressure contraction of the elastic element, the sealing member leaves and opens the operating port.

The product adsorbed by the vacuum adsorption device can be quickly released. The device of the utility model does not affect the normal working state of the vacuum adsorption device.

[0040] See also Figure 1 to Figure 3 , Figure 1 The sealing state of a quick release mechanism for a vacuum adsorption device provided in a certain embodiment is shown, and at this time, the vacuum pipeline 101 of the vacuum adsorption device 1 is in a near vacuum state; Figure 2 The figure shows the opening state of a quick release mechanism for a vacuum adsorption device provided by a certain embodiment, at which time the vacuum pipeline 101 of the vacuum adsorption device 1 is in a vacuum-damaged state. Figure 3 The figure shows a schematic diagram of an explosion structure of a quick release mechanism for a vacuum adsorption device provided in a certain embodiment.

[0041] like Figure 1 to Figure 3 As shown, a quick release mechanism for a vacuum adsorption device comprises:

[0042] A valve body 2, wherein an operating chamber 201 is provided in the valve body 2, wherein the operating chamber 201 is connected to the vacuum pipeline 101 of the vacuum adsorption device 1, and an operating port 201a is further provided on the operating chamber 201, wherein the operating port 201a connects the operating chamber 201 with the external environment;

[0043] An elastic element 3, wherein the elastic element 3 is disposed in the operating cavity 201, wherein one end of the elastic element 3 is a fixed end and the other end is a movable end; the elastic element 3 may be implemented by a telescopic spring or a telescopic spring sheet, and the present embodiment is described by taking a telescopic spring as an example;

[0044] A blocking member 4, wherein the blocking member 4 is fixedly connected to the movable end of the elastic element 3;

[0045] When the elastic element 3 stretches, the blocking member 4 seals the operation port 201 a ; when the elastic element 3 contracts, the blocking member 4 opens the operation port 201 a .

[0046] It is understandable that, based on the defects of the background technology, this embodiment provides a quick release mechanism for a vacuum adsorption device. When the vacuum adsorption device 1 is in a vacuum adsorption state, the vacuum pipeline 101 is in a negative pressure state close to vacuum. Due to the elastic force of the elastic element 3, the elastic element 3 supports the plugging member 4 in the extended state to seal the operation port 201a, so that the operation chamber 201 is also in a negative pressure state close to vacuum. When it is necessary to quickly release the vacuum adsorption state (destroy the vacuum degree), the plugging member 4 is pushed from the operation port 201a. Since the elastic element 3 is contracted by pressure, the plugging member 4 leaves and opens the operation port 201a. The external positive pressure instantly enters the operation chamber 201 and the vacuum pipeline 101 from the operation port 201a, thereby quickly destroying the vacuum degree of the vacuum adsorption device 1 and releasing its vacuum adsorption state. The product adsorbed by the vacuum adsorption device 1 can be quickly released. The device of the utility model does not affect the normal working state of the vacuum adsorption device 1. When the product needs to be released quickly, the vacuum degree of the vacuum adsorption device 1 can be instantly destroyed to achieve the rapid release of the product. It has a simple structure, easy operation, rapid response and high working efficiency.

[0047] Based on the above technical solution, this embodiment can also be improved as follows.

[0048] Preferably, the shape of the blocking member 4 is adapted to the shape of the operating port 201a. For example, in order to reduce the difficulty of processing, the operating port 201a can be set to be circular, and the blocking member 4 can adopt a spherical structure. The spherical blocking member 4 can seal the circular operating port 201a of various sizes smaller than its radial size. The blocking member 4 can preferably adopt a steel ball to ensure its sealing performance and wear resistance.

[0049] In one possible embodiment, Figure 1 to Figure 3 As shown, a first sealing member 5 is provided in the operating cavity 201, and the first sealing member 5 is arranged adjacent to the operating port 201a; when the blocking member 4 closes the operating port 201a, the first sealing member 5 is tightly matched with the blocking member 4. The shape of the first sealing member 5 is adapted to the shape of the operating port 201a. For example, for a circular operating port 201a, the first sealing member 5 can be implemented by an elastic sealing ring. When the operating cavity 201 is sealed, the elastic element 3 pushes the blocking member 4 to press against the first sealing member 5 (sealing ring), and the first sealing member 5 effectively seals the operating port 201a, thereby improving the reliability of the sealing of the operating port 201a.

[0050] In one possible embodiment, the operation port 201 a is arranged along the axial direction of the elastic element 3 .

[0051] In this embodiment, the operation port 201a is coaxially arranged with the elastic element 3 (telescopic spring). When the elastic element 3 stretches, it pushes the blocking member 4 axially to align with the operation port 201a for blocking, so that the operation port 201a is sealed with higher precision.

[0052] In one possible embodiment, the valve seat is connected to the inner wall of the vacuum pipe 101 of the vacuum adsorption device 1 via a thread A. Figure 1-2 As shown, an external thread is arranged on the outer periphery of the valve seat, and an internal thread is arranged on the inner wall of the vacuum pipeline 101 of the vacuum adsorption device 1, and the installation of the valve seat is achieved through the meshing action of the external thread and the internal thread.

[0053] In this embodiment, the valve seat is fixedly installed and sealed by the thread A, which is beneficial to maintaining the vacuum degree of the operating chamber 201 and the vacuum pipeline 101 and reducing the influence of external pressure on the pressure in the operating chamber 201.

[0054] In one possible embodiment, Figure 3 As shown, a straight groove 202 is provided on the outer side of the valve body 2, and the length direction of the straight groove 202 is perpendicular to the axial direction of the thread A on the valve seat. Preferably, the straight groove 202 can overlap with the operation port 201a shown.

[0055] In this embodiment, the straight groove 202 is coaxially arranged with the valve seat, so that it is convenient to insert the installation tool into the straight groove 202 to disassemble and install the valve seat, thereby reducing the difficulty of installation.

[0056] In one possible embodiment, the device further includes a second sealing member 6 , which is disposed between the valve body 2 and the vacuum pipeline 101 of the vacuum adsorption device 1 to seal the vacuum pipeline 101 of the vacuum adsorption device 1 .

[0057] In this embodiment, the second sealing member 6 can preferably be a sealing ring with elasticity, such as Figure 1-2 As shown, the second sealing member 6 prevents the external positive pressure from interfering with the vacuum degree of the vacuum pipeline 101 through the gap between the outer periphery of the valve seat and the vacuum pipeline 101, thereby improving the air tightness of the valve seat.

[0058] In one possible embodiment, an annular groove 203 is provided on the outer periphery of the valve body 2 , and the second sealing member 6 is sleeved in the annular groove 203 and tightly matched with the inner wall of the vacuum pipeline 101 of the vacuum adsorption device 1 .

[0059] In this embodiment, the annular groove 203 limits the second sealing member 6 to prevent the second sealing member 6 from shifting during the process of rotating the valve seat for installation or removal, thereby ensuring the air tightness of the valve seat.

[0060] In one possible embodiment, a first limit platform 101a is provided in the vacuum pipeline 101 of the vacuum adsorption device 1, and the first limit platform 101a is arranged along the axial direction of the elastic element 3, and the first limit platform 101a cooperates with the fixed end of the elastic element 3.

[0061] In this embodiment, the first limiting platform 101 a is tightly matched with the fixed end of the elastic element 3 , so as to limit the elastic element 3 and provide positioning and structural support for the elastic element 3 .

[0062] In one possible embodiment, a second limit platform 101 b is provided in the vacuum pipeline 101 of the vacuum adsorption device 1 , a third limit platform 204 is provided on the periphery of the valve seat, and the second limit platform 101 b is matched with the third limit platform 204 .

[0063] In this embodiment, the second limiting platform 101b and the third limiting platform 204 are tightly matched with each other, so as to limit the valve seat and optimize the installation depth of the valve seat so that the valve seat can be positioned to a preferred and optimal position during installation.

[0064] In one possible embodiment, the device further includes an operating tool 7 , and the operating tool 7 is adapted to the operating port 201 a ; the operating tool 7 can be extended into the operating port 201 a to push the blocking member 4 .

[0065] In this embodiment, the operating tool 7 is inserted into the operating port 201a to push the blocking member 4. When the elastic element 3 contracts, the operating port 201a can be released, so that the external positive pressure enters the operating cavity 201 and the vacuum pipeline 101 from the operating port 201a, thereby destroying the vacuum degree and quickly releasing the grasped product.

[0066] The utility model provides a quick release mechanism for a vacuum adsorption device. When installing, firstly, the second sealing member 6 (sealing ring) is sleeved in the annular groove 203 on the outer periphery of the valve seat, and the first sealing member 5 (sealing ring), the plugging member 4 (steel ball), and the elastic element 3 (telescopic spring) are sequentially placed in the operating chamber 201 of the valve seat, and then the valve seat together with its internal parts are pushed into the installation position of the vacuum pipeline 101 of the vacuum adsorption device 1. The first limit platform 101a positions the fixed end of the elastic element 3, and the plugging member 4 is tightly matched with the movable end of the elastic element 3. The installation tool is inserted into the slot 202 of the valve seat and the valve seat is rotated to complete the thread A connection between the valve seat and the inner wall of the vacuum pipeline 101 of the vacuum adsorption device 1, until the second limit platform 101b and the third limit platform 204 are tightly matched with each other. At this time, the elastic element 3 is in an extended state. Due to the elastic effect of the elastic element 3, the elastic element 3 compresses the blocking member 4 and the first sealing member 5 to seal the operating port 201a of the operating chamber 201. The pressure in the operating chamber 201 is consistent with that in the vacuum pipeline 101, for example, in a negative pressure state close to vacuum. When it is necessary to quickly release the vacuum adsorption state (destroy the vacuum degree), the operating tool 7 is removed from the vacuum pipe 101. Figure 2 The plugging member 4 is pushed into the operation port 201a in the direction of A, and the elastic element 3 contracts under the pressure. As the plugging member 4 leaves and opens the operation port 201a, the external positive pressure instantly enters the operation chamber 201 through the operation port 201a. Figure 2 The vacuum pipe 101 is entered in the R direction, thereby destroying the vacuum degree of the vacuum adsorption device 1 and releasing its vacuum adsorption state, and the product adsorbed by the vacuum adsorption device 1 can be quickly released. The device of the utility model does not affect the normal working state of the vacuum adsorption device 1, and can achieve rapid release of the product by instantly destroying the vacuum degree of the vacuum adsorption device 1 when the product needs to be released quickly. It has a simple structure, is easy to operate, has a quick response, and has high working efficiency.
