Description

Technical Field

[0001] The embodiments of this utility model relate to the field of magnetic levitation molecular pump installation fixture technology. More specifically, this utility model relates to a magnetic levitation molecular pump controller sealing gasket installation fixture. Background Technology

[0002] As a core control unit in industrial automation, automotive electronics, and smart home applications, the controller's sealing performance directly affects the device's waterproof and dustproof capabilities, operational stability, and lifespan. The assembly of the rubber gasket and the stainless steel flat cover is a crucial step in the controller's protective structure. Reliable bonding and positioning are essential to ensure a tight seal; therefore, the quality and efficiency of this assembly process are of great importance to the large-scale production of various controllers.

[0003] Currently, the assembly of the cover plate and rubber sealing gasket in the industry generally adopts a manual operation mode. The specific process is as follows: the operator first holds the rubber sealing gasket with 3M adhesive backing, manually aligns it with the preset position of the controller's flat cover plate, and sticks the sealing gasket in place. After the sealing gasket is pasted, the cover plate with the assembled sealing gasket is then manually aligned and assembled with the controller body, finally completing the assembly of the controller's sealing structure.

[0004] In existing technologies, manual assembly methods reveal several unavoidable drawbacks in actual production: 1) Due to the flat structure of the cover plate without a positioning reference, there is a lack of effective constraints when manually pasting the sealing gasket. This easily leads to problems such as gasket misalignment, tilting, or uneven gaps between the gasket and the cover plate edge, resulting in sealing performance failure after subsequent assembly with the controller body. This increases the quality risks of water leakage and dust ingress, seriously affecting the lifespan and operational reliability of the controller. 2) Manual positioning requires repeated adjustments to the sealing gasket position to ensure accuracy as much as possible. The operation process is cumbersome and time-consuming. At the same time, the assembly of the cover plate with the controller body after the sealing gasket is pasted also requires secondary manual alignment, further extending the assembly cycle of a single product and making it difficult to meet the efficiency requirements of large-scale production. 3) The operator's skill level, fatigue level, and other subjective factors directly affect the positioning accuracy of the sealing gasket, resulting in significant differences in the assembly quality of the same batch of products. This increases the workload of subsequent quality inspection and the rework cost of defective products, which is not conducive to standardized control of the production process. Utility Model Content

[0005] To address one or more of the technical problems mentioned above, this utility model provides a sealing gasket installation fixture for a magnetic levitation molecular pump controller, which improves the efficiency and standardization of gasket bonding and ensures the sealing effect of the gasket.

[0006] This utility model provides a sealing gasket installation fixture for a magnetic levitation molecular pump controller, including a fixture body, the top of which is formed with the following vertically stepped features: a cover plate placement groove for accommodating the cover plate of the controller, the groove contour of which is adapted to the outer contour of the cover plate; and a sealing gasket placement groove located below a predetermined position of the cover plate placement groove for accommodating the sealing gasket of the cover plate, the groove contour of which is adapted to the outer contour of the sealing gasket.

[0007] In some embodiments, the depth of the gasket placement groove is less than or equal to the thickness of the gasket.

[0008] In some embodiments, a plurality of disassembly grooves are formed on the groove wall of the cover plate placement groove.

[0009] In some embodiments, the disassembly groove is constructed as a through groove that penetrates the wall of the cover plate placement groove.

[0010] In some embodiments, the disassembly groove is constructed as an arcuate groove formed on the groove wall, the arcuate bottom surface of the arcuate groove extending to the bottom of the cover plate placement groove.

[0011] In some embodiments, the system further includes a plurality of resilient top posts, which are vertically disposed on the bottom of the sealing gasket placement groove and / or the cover plate placement groove.

[0012] In some embodiments, the elastic top post is provided with a plurality of vent holes, which are connected axially and radially along the elastic top post.

[0013] In some embodiments, the device further includes a plurality of vent holes and / or vent grooves, wherein the plurality of vent holes are formed vertically at the bottom of the sealing gasket placement groove, and the plurality of vent grooves are formed laterally at the bottom of the sealing gasket placement groove.

[0014] In some embodiments, a positioning post is also included, which is formed at the bottom of the sealing gasket placement groove and is used to mate with the mounting hole of the cover plate.

[0015] In some embodiments, an anti-slip pad is also included, which is disposed on the bottom of the tooling body.

[0016] Using the aforementioned mounting fixture for the magnetic levitation molecular pump controller gasket, a positioning reference is formed through the cover plate placement groove to accurately position the cover plate. Similarly, a positioning reference is formed through the gasket placement groove to accurately position the gasket. By placing the gasket placement groove at the preset position of the cover plate placement groove, accurate positioning is also achieved when the gasket is adhered to the cover plate. This effectively reduces problems such as offset, tilting, or uneven gaps between the gasket and the cover plate edge during the gasket adhesion process, thereby improving the sealing effect, extending the controller's service life, and enhancing operational reliability. Simultaneously, it improves the gasket adhesion efficiency, meeting the efficiency requirements of large-scale production. Furthermore, it reduces the impact of operator subjectivity on the gasket positioning accuracy, lowers the workload of subsequent quality inspection and the rework cost of defective products, and facilitates standardized control of the production process.

[0022] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Figure 1 and Figure 2The structure of a magnetic levitation molecular pump controller gasket mounting fixture 100 according to an embodiment of the present invention is shown. Figure 1 and Figure 2 As shown, the magnetic levitation molecular pump controller gasket mounting fixture 100 includes a fixture body 1, the top of which is formed with the following vertically stepped features: a cover plate placement groove 2 for accommodating the cover plate 200 of the controller, the groove contour of the cover plate placement groove 2 being adapted to the outer contour of the cover plate 200; and a gasket placement groove 3 located below a preset position of the cover plate placement groove 2 for accommodating the gasket 300 of the cover plate 200, the groove contour of the gasket placement groove 3 being adapted to the outer contour of the gasket 300.

[0024] According to the embodiment of this utility model, the magnetic levitation molecular pump controller sealing gasket mounting fixture 100, in specific use, is combined with... Figure 3 and Figure 4 As shown, place the fixture body 1 on the platform. First, place the sealing gasket 300 (including adhesive backing) into the sealing gasket placement groove 3 (the groove outline of the sealing gasket placement groove 3 matches the outer outline of the sealing gasket 300) to position the sealing gasket 300. Place the cover plate 200 into the cover plate placement groove 2 (the groove outline of the cover plate placement groove 2 matches the outer outline of the cover plate 200), and press down firmly to ensure that the sealing gasket 300 and the cover plate 200 are firmly adhered. Then, remove the entire assembly after it has been firmly adhered for use.

[0025] According to the above configuration, the sealing gasket mounting fixture 100 of the magnetic levitation molecular pump controller in this embodiment of the present invention forms a positioning reference through the cover plate placement groove 2 to accurately position the cover plate 200. Similarly, a positioning reference is formed through the sealing gasket placement groove 3 to accurately position the sealing gasket 300. By setting the sealing gasket placement groove 3 at a preset position in the cover plate placement groove 2, the sealing gasket 300 can also be accurately positioned when pasted onto the cover plate 200. This effectively reduces the problems of offset, tilting, or uneven gap between the sealing gasket 300 and the edge of the cover plate 200 during the pasting process, thereby improving the sealing effect, extending the service life and operational reliability of the controller. At the same time, it also improves the pasting efficiency of the sealing gasket 300, meeting the efficiency requirements of large-scale production. In addition, it reduces the impact of the operator's subjective factors on the positioning accuracy of the sealing gasket 300, reduces the workload of subsequent quality inspection and the rework cost of defective products, and is conducive to the standardized management and control of the production process.

[0026] In some embodiments, the depth of the sealing gasket placement groove 3 is less than or equal to the thickness of the sealing gasket 300.

[0027] With this setting, after the sealing gasket 300 is placed in the sealing gasket placement groove 3, a portion of it protrudes after the adhesive is used, so that the cover plate 200 can better adhere to the sealing gasket 300 during the pressing process, thereby making the sealing gasket 300 adhere more firmly.

[0028] Please refer to Figure 1 In some embodiments, a plurality of disassembly grooves 21 may be formed on the groove wall of the cover plate placement groove 2.

[0029] With this design, after the cover plate 200 is pasted, it may be flush with or slightly higher than the cover plate placement groove 2, and the back of the cover plate 200 is mostly smooth. This application provides a disassembly groove 21, which allows the operator to pick up the cover plate 200 with their fingers to complete the disassembly without affecting the positioning and assembly of the sealing gasket 300 and the cover plate 200.

[0030] In one embodiment, the disassembly groove 21 can be configured as a through groove that penetrates the wall of the cover plate placement groove 2, allowing the operator to remove the back plate from the side of the tooling body 1.

[0031] In another embodiment, the disassembly groove 21 is constructed as an arc-shaped groove formed on the groove wall, with the arc-shaped bottom surface of the groove extending to the bottom of the cover plate placement groove 2, allowing the operator to slide their fingers to the bottom of the back plate to remove it.

[0032] Please refer to Figure 2 In some embodiments, it may also include a plurality of elastic top posts 4, which are arranged vertically on the bottom of the sealing gasket placement groove 3 and / or the cover plate placement groove 2.

[0033] Specifically, a groove is formed on the bottom of the sealing gasket placement groove 3 and / or the cover plate placement groove 2, and the column of the elastic top post 4 is slidably disposed in the groove. The column of the elastic top post 4 elastically abuts against a spring. In this application, preferably, four elastic top posts 4 can be provided on the bottom of the sealing gasket placement groove 3. During use, during the pasting process, the elastic top posts 4 are in a downward position due to pressure. After the downward pressure is removed, the elastic top posts 4 lift the cover plate 200 by the force of the spring, so that the sealing gasket 300 and the cover plate 200 detach from the cover plate placement groove 2 of the tooling body 1, thereby making the removal of the cover plate 200 easier.

[0034] Please continue to refer to Figure 2 In some embodiments, the elastic top post 4 may be provided with a plurality of vent holes 41, which are connected axially and radially along the elastic top post 4.

[0035] With this setting, the elastic top column 4 is provided with an exhaust hole 41, which can quickly discharge the gas in the compression space when the elastic top column 4 is pressed down, thereby making it easier to press down the cover plate 200.

[0036] Please return Figure 1 In some embodiments, it also includes a plurality of vent holes 51 and / or vent grooves 52, wherein the plurality of vent holes 51 are formed vertically at the bottom of the sealing gasket placement groove 3, and the plurality of vent grooves 52 are formed laterally at the bottom of the sealing gasket placement groove 3.

[0037] With this configuration, the cooperation of the vent hole 51 and the vent groove 52 can prevent the formation of a large vacuum area between the sealing gasket 300 and the tooling body 1, making it easier for the sealing gasket 300 to separate from the tooling body 1.

[0038] Please continue to refer to Figure 1 In some embodiments, a positioning post 61 may also be included, which is formed at the bottom of the sealing gasket placement groove 3 and is used to mate with the mounting hole of the cover plate 200.

[0039] The above settings enable the cover plate 200 to be placed in the cover plate placement slot 2 more quickly.

[0040] In some embodiments, an anti-slip pad (not shown) is also included, which is disposed at the bottom of the tooling body 1 so that the tooling body 1 can be kept stable by the anti-slip pad during the pressure bonding process by the operator.
