Background

"vacuum chamber" refers to an enclosed space designed to operate under vacuum. They are used in a wide range of applications such as scientific research experiments, semiconductor processing, materials science research, etc.

In order to ensure the normal use of the vacuum cavity, the vacuum cavity is often required to be uncapped or sealed by using a vacuum cavity uncapping device. A key problem that vacuum cavity door opening devices need to handle is how to open and close the cavity without damaging the vacuum environment. Thus, the prior art introduced a four-post tripod mechanism. The device specifically comprises four guide posts, a linear bearing and a driving device, wherein when the device needs to open or close the vacuum cavity, the driving device (such as a cylinder or a motor) is activated, and can generate pushing force or pulling force.

Some embodiments of the utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

Referring to fig. 1-3, an embodiment of the present utility model provides a vacuum cavity cover opening device 100, which includes a driving assembly 10, a sleeve 20 and a turnover member 30 sequentially connected, wherein the driving assembly 10 is used for providing power, and the turnover member 30 is fixed on the vacuum cavity, so that the turnover member 30 can be driven to turn when the driving assembly 10 turns over.

Specifically, the driving assembly 10 includes a driving member 11 and a telescopic member 12 disposed on a driving shaft of the driving member 11, and the telescopic member 12 includes a body 121 and a guide portion 122 disposed on the body 121.

The driving assembly 10 is a power part of the vacuum cavity door opening device 100. The drive assembly 10 comprises two parts, a drive member 11 and a telescopic member 12. In one embodiment, the driving member 11 is an electric motor, a cylinder or other device capable of generating a driving force. When the driving member 11 is activated, a forward or backward force can be generated, which is transmitted to the telescopic member 12 via the driving shaft.

Further, the telescopic member 12 is provided on the drive shaft of the driving member 11. It has a body 121, and a guiding part 122 is arranged on the body 121. When the driving member 11 is activated, the force transmitted through the driving shaft causes the telescopic member 12 to perform a telescopic or contractive movement. The expansion and contraction of the expansion and contraction member 12 in space is realized by the expansion and contraction of the body 121.

In one embodiment, telescoping member 12 is a telescoping rod construction.

Further, along the length direction of the sleeve 20, the sleeve 20 is provided with a guide groove 21 on the outer peripheral wall thereof, the body 121 is disposed in the inner cavity of the sleeve 20, and the guide portion 122 extends from the body 121 into the guide groove 21.

It should be noted that, the sleeve 20 is provided with an inner cavity, and the inner cavity is used for installing the body 121 of the telescopic member 12. The outer peripheral wall of the sleeve 20 is provided with a guide groove 21. The guide groove 21 functions to cooperate with the guide portion 122 of the telescoping member 12 to guide the telescoping member 12 along a particular path during movement.

Further, the guide portion 122 is a part of the telescopic member 12, and is provided on the body 121 of the telescopic member 12. The guide portion 122 is provided to engage the guide groove 21 in the sleeve 20 to allow the telescopic member 12 to move along a specific path during telescopic movement.

In one embodiment, the body 121 is a rod body of a telescopic rod, and the guiding portion 122 is a protruding block structure disposed on the telescopic rod body 121 and protruding outwards.

In one embodiment, flip 30 is a generally one-piece structure.

In one embodiment, the turning member 30 is disposed on the body 121, and the turning member 30 has a fixing surface 30a for fixing the vacuum chamber, so that the vacuum chamber is driven to extend and rotate by the telescopic member 12 and the turning member 30 when the driving member 11 is operated.

The flipping part 30 is disposed on the body 121 of the telescopic part 12. The tilting member 30 has a fixing surface 30a, and the fixing surface 30a can be used to fix the vacuum chamber. When the driving member 11 is operated, the overturning member 30 can drive the vacuum chamber to extend and rotate outwards through the movement of the telescopic member 12 and the guiding portion 122. The purpose of rotation is when opening the vacuum cavity, can overturn the vacuum cavity to a suitable angle, makes things convenient for the staff to operate.

In summary, the vacuum cavity cover opening device 100 realizes the accurate control of opening and closing of the vacuum cavity through the cooperation of the driving assembly 10, the sleeve 20 and the overturning piece 30, and can rotate the cavity to a proper angle in the opening process, so that the operator can conveniently take out objects or perform other operations. The design has strong practicability and convenient operation.

In one embodiment, the first groove 21a is linear and extends along the length of the sleeve 20. Due to the rectilinear shape of the first slot 21a, it is mainly responsible for controlling the rectilinear movement, i.e. the telescopic movement, of the telescopic element 12 inside the sleeve 20. When the driving member 11 drives the telescopic member 12 to perform the linear motion, the guide portion 122 on the telescopic member 12 moves along the linear path of the first groove 21 a. This ensures that the telescopic movement of the telescopic element 12 is accurate and rectilinear.

Further, the second groove 21b is an arc-shaped groove, and compared with the first groove 21a, the arc-shaped design of the second groove 21b can enable the telescopic member 12 and the guiding portion 122 to perform telescopic movement and also perform rotation movement at a certain angle. That is, when the driving member 11 drives the telescopic member 12, the guide portion 122 moves along the arc-shaped path of the second groove 21b, achieving the fusion of the telescopic and rotational movements.

In another embodiment, the guide groove 21 is an arc groove. It should be noted that the guide groove 21 is designed to be arc-shaped in order to control and guide the rotational movement of the telescopic member 12 (and the guide portion 122 thereof). When the driving member 11 is activated, driving force is transmitted to the telescopic member 12 through the driving shaft, and the telescopic member 12 moves along the arc-shaped guide groove 21 in the sleeve 20. Specifically, the arcuate guide slot 21 is designed such that the telescoping member 12 can perform a rotational movement while performing a linear telescoping movement. As the guide 122 of the telescopic member 12 moves along the arcuate guide slot 21, it will rotate about the centre of the sleeve 20. This rotational movement allows the flip 30 (which is provided on the body 121 of the telescopic member 12) to rotate while extending out of the cavity. Thus, the vacuum chamber is pushed out by the flipping member 30 and is rotated to an angle suitable for operation.

In summary, the design of the arc-shaped guide groove 21 makes the vacuum cavity cover opening device 100 not only perform linear expansion movement but also perform rotational movement during the process of opening or closing the vacuum cavity. In this way, subsequent operations, such as removal or insertion of materials, can be performed more conveniently. This design greatly increases the flexibility and practicality of the device.

Further, the vacuum cavity door apparatus 100 further includes a connection assembly 40. The connecting assembly 40 includes a first connecting plate 41 and a second connecting plate 42, and the telescopic member 12 penetrates through the first connecting plate 41 and the second connecting plate 42, and two ends of the sleeve 20 are respectively abutted against the first connecting plate 41 and the second connecting plate 42.

Wherein the first connection plate 41 and the second connection plate 42 are core components of the connection assembly 40. The telescopic element 12 is arranged through the first connecting plate 41 and the second connecting plate 42, and is designed mainly in such a way that the telescopic element 12 can perform telescopic movement between the two connecting plates, and the stability and accuracy of the telescopic element are always maintained in the whole movement process. The two connection plates structurally provide a stable movement axis for the telescopic member 12, ensuring that the telescopic member 12 can accurately perform linear movement under the drive of the driving member 11.

Further, both ends of the sleeve 20 respectively abut against the first connecting plate 41 and the second connecting plate 42. The purpose of this is primarily to fix the position of the sleeve 20 so that the sleeve 20 remains stable during movement of the device. The sleeve 20 is fixed to the connection plate so that the telescopic member 12 inside thereof can be precisely moved along a path set inside the sleeve 20 when performing telescopic movement.

In summary, the above arrangement enables the telescopic member 12 to perform precise linear telescopic movement in the sleeve 20, and the rotary movement of the turning member 30 during the process of opening or closing the vacuum chamber is realized through the guiding of the sleeve 20. During the operation of the vacuum cavity uncapping device 100, the stability and the movement precision of the whole device are ensured by stably positioning the telescopic member 12 and the sleeve 20 through the first connecting plate 41 and the second connecting plate 42.

Further, the first connecting plate 41 is provided with a first connecting groove 41a, the second connecting plate 42 is provided with a second connecting groove 42a, and two ends of the sleeve 20 respectively abut against the first connecting groove 41a and the second connecting groove 42 a.

The first connection groove 41a is formed in the first connection plate 41. The primary function is to receive and secure one end of the sleeve 20 so that the sleeve 20 may remain stable during movement of the device. Similarly, the second connecting groove 42a is formed on the second connecting plate 42. Its primary function is also to receive and secure the other end of the sleeve 20. In this way, the sleeve 20 maintains its position and stability, both during telescopic and rotational movements of the device.

In summary, by abutting the two ends of the sleeve 20 in the first connecting groove 41a and the second connecting groove 42a, respectively, it is possible to ensure that the sleeve 20 always maintains a fixed position and a stable movement track when the device performs telescopic and rotational movements. This ensures the accuracy of the telescopic and rotational movements of the telescopic member 12 within the sleeve 20, thereby improving the overall movement accuracy and stability of the vacuum cavity door apparatus 100. The design ensures that the whole device has high precision and high stability in the operation process, thereby improving the working efficiency and prolonging the service life of equipment.

The width of the first and second coupling grooves 41a and 42a is equal to the thickness of the sleeve 20. It should be noted that the width of the connecting groove is exactly equal to the thickness of the sleeve 20, which means that the sleeve 20 can be positioned and fixed in the connecting groove accurately, without extra space for the sleeve 20 to move or deviate in the connecting groove. In this way, the sleeve 20 can be kept stable and will not move or displace in the coupling groove due to movement or vibration of the device. The above solution ensures that the sleeve 20 is always kept in a precisely positioned state, so that the telescopic member 12 in the sleeve 20 can perform telescopic movement along a precise path.

Further, the second connecting plate 42 has a plurality of first fixing holes 42b penetrating through the second connecting slot 42a, and the sleeve 20 has a plurality of second fixing holes 22 corresponding to the first fixing holes 42 b. Screws can extend into the first and second opposite fixing holes 42b and 22 to fix the sleeve 20 to the second connecting plate 42, and the first and second fixing holes 42b and 22 are designed to accommodate the screws, so that the screws can pass through and lock the sleeve 20 and the second connecting plate 42, thereby fixing the two.

Still further, the vacuum chamber door apparatus 100 further includes a fixing member 50. The fixing member 50 is disposed at an end portion of the telescopic member 12 extending out of the first connecting plate 41, and is used for fixing the telescopic member 12 and the turnover member 30. The fixing member 50 fixes the telescopic member 12 and the tilting member 30, so that the telescopic movement of the telescopic member 12 may be received by the tilting member 30 and converted into the opening movement of the vacuum chamber. The presence of the fixing member 50 ensures a stable connection of the telescopic member 12 with the tilting member 30, so that the movement of the telescopic member 12 can be effectively converted into the movement of the tilting member 30 without losing efficiency due to loosening or sliding of the connection portion. At the same time, by fixing the telescopic member 12 and the tilting member 30, the fixing member 50 also ensures the stability and reliability of the door opening device during operation.

In one embodiment, the fastener 50 is a nut.

Further, the vacuum cavity cover opening device 100 further includes a third connecting plate 60 disposed opposite to the second connecting plate 42. The second connecting plate 42 is provided with a first connecting hole 42c, the third connecting plate 60 is provided with a second connecting hole 60a, the telescopic member 12 extends out of the first connecting hole 42c and the second connecting hole 60a, and the outer circumferential surface of the telescopic member 12 abuts against the inner circumferential wall of the first connecting hole 42 c.

Specifically, the confronting arrangement of the second and third connection plates 42, 60 creates a "grip" structure that allows the telescoping member 12 to be stably secured and guided during movement. This structure can ensure the moving direction of the expansion member 12, prevent it from deviating or swinging during driving, and thus ensure the precise fitting of the tilting member 30 with the expansion member 12 and the precise opening and closing of the vacuum chamber.

More specifically, the second connecting plate 42 is provided with a first connecting hole 42c, and the third connecting plate 60 is provided with a second connecting hole 60a, through which the expansion element 12 protrudes. This design further ensures stable movement of the telescoping member 12, preventing lateral shifting thereof during movement. In addition, this close mating relationship also provides good guidance and stability for movement of the telescoping member 12, as the outer peripheral surface of the telescoping member 12 abuts against the inner peripheral wall of the first attachment hole 42 c.

Further, the vacuum cavity door apparatus 100 further includes a plurality of posts 70, and the posts 70 are parallel to each other and abut against the second connecting plate 42 and the third connecting plate 60.

It should be noted that the arrangement of the plurality of columns 70 corresponds to enhancing the stability of the apparatus. Since the posts 70 directly connect the second and third connection plates 42, 60, they form a firm frame structure that provides good support for the entire vacuum cavity door apparatus 100, thereby improving the stability of the apparatus during operation.

Further, since the columns 70 are disposed in parallel with each other on the second and third connection plates 42 and 60, they can uniformly distribute the force generated from the driving assembly 10, guaranteeing the balance of the device. In this way, deviations or inclinations of the device during operation, which occur as a result of uneven distribution of forces, can be avoided, so that an accurate operation of the device is ensured.

Still further, the posts 70 not only provide additional support, but also prevent the web from twisting or deforming due to stresses, particularly torsional stresses, that occur during operation of the device. In this way, the key components such as the connecting plate and the upright post 70 can be ensured to be always kept in the correct position and state, and the accurate operation of the device is ensured.

Still further, the plurality of posts 70 may form a protective frame that provides some protection to the internal drive assembly 10, such as the telescoping member 12 and the drive member 11, from accidental damage to these critical components during operation.

The vacuum cavity uncapping device 100 provided by the above is provided with the driving assembly 10, the sleeve 20 and the overturning piece 30, and the guide groove 21 is formed in the sleeve 20, the guide part 122 on the telescopic piece 12 stretches into the guide groove 21 to be arranged, so that when the vacuum cavity needs to be uncapped, the driving assembly 10 drives the telescopic piece 12 to stretch out and draw back and move in the guide groove 21 on the sleeve 20, and the overturning piece 30 is driven to stretch out and rotate outwards, so that when the vacuum cavity is uncapped, the vacuum cavity can be overturned to a proper angle for a worker to take up and take materials.

While the utility model has been described with respect to the above embodiments, it should be noted that modifications can be made by those skilled in the art without departing from the inventive concept, and these are all within the scope of the utility model.
