Description

Technical Field

[0001] The present application relates to the technical field of capacitor film cutting, and in particular to a capacitor film vacuum cutting device. Background Art

[0002] The manufacturing process is a crucial element in the construction of capacitance diaphragm vacuum gauges. The performance and reliability of these precision sensors depend heavily on the precision and quality control during their manufacturing. While a wide variety of capacitance diaphragm vacuum gauges exist on the market, the core manufacturing process is often controlled by a few leading multinational companies.

[0003] As a core component of pressure sensors like capacitive thin-film vacuum gauges, the pressure-sensing diaphragm requires precise control during the welding process to ensure product performance and quality. Accurate control of welding process parameters not only ensures welding quality but also improves production efficiency, ultimately impacting overall product performance. The upper and lower covers sandwich the capacitive diaphragm before welding, and how to align and install the capacitive diaphragm before welding has become a pressing challenge for those skilled in the art.

[0035] Figure 1 A schematic diagram showing the main structure according to an embodiment of the present application is shown. Figure 1As shown, the capacitor film vacuum cutting device of the embodiment of the present application includes: an upper cover 210, a lower cover 220, an upper fixing seat 110, an upper fixing shaft 710, a lower fixing seat 120, a lower fixing shaft 720 and a turning tool 800, the upper fixing seat 110 and the lower fixing seat 120 are separated by a preset distance, the upper fixing shaft 710 is rotatably arranged on the upper fixing seat 110, and the axial length direction is perpendicular to the plate direction of the upper fixing seat 110, the lower fixing shaft 720 is rotatably arranged on the lower fixing seat 120, and the lower fixing shaft 720 is rotatably arranged on the lower fixing seat 120, and the lower fixing shaft 720 is rotatably arranged on the lower fixing seat 120. 0 is perpendicular to the plate direction of the lower fixed seat 120, the upper cover 210 is arranged at one end of the axial length direction of the upper fixed shaft 710, the lower cover 220 is arranged at one end of the axial length direction of the lower fixed shaft 720, and the upper cover 210 is in contact with the lower cover 220, clamping the capacitor film 300, the turning tool 800 is arranged on the lower fixed seat 120, adjacent to the edge position of the upper cover 210 and the lower cover 220, and the upper fixed shaft 710 is suitable for connecting to the rotating device to drive the upper fixed shaft 710 to rotate relative to the turning tool 800.

[0036] In this specific embodiment, the capacitor film 300 can be manually clamped between the upper cover 210 and the lower cover 220 by rotating the upper fixed shaft 710 relative to the turning tool 800, and the excess capacitor film 300 can be cut to form a capacitor film 300 that matches the upper cover 210 and the lower cover 220. Specifically, the upper fixed base 110 and the lower fixed base 120 maintain a certain preset distance to ensure the stability and accuracy of the cutting process. The upper fixed shaft 710 is mounted on the upper fixed base 110 and can rotate circumferentially. Its axial length direction is perpendicular to the plate direction of the upper fixed base 110, so that the upper fixed shaft 710 can drive the upper cover 210 and the capacitor film 300 clamped therein to perform circular motion. Similarly, the lower fixed shaft 720 is mounted on the lower fixed base 120, and its axial length direction is perpendicular to the plate direction of the lower fixed base 120. The lower cover 220 is arranged at one end of the axial length direction of the lower fixed shaft 720, corresponding to the upper cover 210, and together clamps and fixes the capacitor film 300. When the upper cover 210 and the lower cover 220 are in a closed state, they clamp the larger capacitor film 300. The cutting tool 800 is disposed on the lower fixed seat 120, and the cutting position of the cutting tool 800 is close to the abutment position of the upper cover 210 and the lower cover 220. By rotating the upper fixed shaft 710, the excess portion of the capacitor film 300 outside the upper cover 210 and the lower cover 220 can be cut. In this way, the present application provides a seamless installation for the welding of the upper cover 210, the capacitor film 300, and the lower cover 220, avoiding the presence of excess capacitor film 300 relative to the upper cover 210 and the lower cover 220, and making it more convenient to operate on the capacitor film 300 that is clamped and matched by the upper cover 210 and the lower cover 220.

[0037] Furthermore, in this embodiment, the lower fixed shaft 720 can be set on the lower fixed base 120, can rotate circumferentially relative to the lower fixed base 120, and can slide axially relative to the lower fixed base 120, move toward the upper cover 210, and clamp the capacitor film 300 located between the upper cover 210 and the lower cover 220.

[0038] In one embodiment, the upper fixed shaft 710 and the lower fixed shaft 720 are coaxially arranged, and the axes of the upper fixed shaft 710 and the lower fixed shaft 720 are located on the same straight line. Specifically, the upper fixed shaft 710 is mounted on the upper fixed base 110, and the lower fixed shaft 720 is mounted on the lower fixed base 120. Because the upper fixed shaft 710 and the lower fixed shaft 720 are coaxially arranged, when the external rotating device drives the upper fixed shaft 710 to rotate, the lower fixed shaft 720 will also rotate at the same speed and direction, thereby ensuring that the capacitor film 300 clamped by the upper cover 210 and the lower cover 220 can be cut evenly and smoothly by the turning tool 800.

[0039] Among them, the coaxial setting also helps to reduce vibration and deviation during the cutting process, improving cutting accuracy and efficiency.

[0040] In one specific embodiment, a first mounting groove is defined at one axial end of the upper fixed shaft 710. The first mounting groove matches the upper cover 210, and the upper cover 210 is embedded within the first mounting groove. A second mounting groove is defined at one axial end of the lower fixed shaft 720. The second mounting groove matches the lower cover 220, and the lower cover 220 is embedded within the second mounting groove. To more securely connect and support the upper cover 210 and the lower cover 220, the upper fixed shaft 710 defines a first mounting groove at one axial end. The shape and size of the first mounting groove match those of the upper cover 210, allowing the upper cover 210 to be tightly and securely embedded within the first mounting groove, thereby enhancing the connection strength between the upper cover 210 and the upper fixed shaft 710 and ensuring that the upper cover 210 remains stable during rotation and is less likely to deviate or wobble. Similarly, the lower fixed shaft 720 is also provided with a second mounting groove at one axial end thereof. This second mounting groove matches the structure of the lower cover 220, so that the lower cover 220 can be embedded inside the second mounting groove, thereby improving the connection stability between the lower cover 220 and the lower fixed shaft 720, and ensuring that the lower cover 220 can maintain a precise position during the cutting process, thereby further improving the cutting accuracy.

[0041] In a specific embodiment, the upper fixing seat 110 and the lower fixing seat 120 have a preset thickness, and the preset thickness ensures that the upper fixing seat 110 and the lower fixing seat 120 can provide sufficient supporting force after being assembled.

[0042] In one embodiment, the capacitive film vacuum cutting device further includes a torque wrench 400, which is mounted on the lower fixing base 120 and connected to the lower fixing shaft 720. Rotating the torque wrench 400 drives the lower fixing shaft 720 toward the upper fixing shaft 710. The torque wrench 400 is mounted on the lower fixing base 120 and connected to the lower fixing shaft 720. When a user needs to adjust or operate the device, they simply rotate the torque wrench 400, which effectively drives the lower fixing shaft 720 to move along a predetermined trajectory toward the upper fixing shaft 710.

[0043] In one embodiment, the capacitor film vacuum cutting apparatus further includes a servo motor 500 and a coupling 600. The servo motor 500 is connected to an upper fixed shaft 710 via the coupling 600, driving the upper fixed shaft 710 to rotate circumferentially. After the upper cover 210 and the lower cover 220 clamp the capacitor film 300, the servo motor 500 is turned on, driving the upper fixed shaft 710 to rotate circumferentially via the coupling 600, thereby allowing the cutting tool 800 to cut the excess portion of the capacitor film 300.

[0044] In a specific embodiment, the cross-sectional diameter of the capacitor film 300 is larger than the cross-sectional diameter of the upper cover 210 and the cross-sectional diameter of the lower cover 220. The capacitor film 300 can be clamped between the upper cover 210 and the lower cover 220 by hand, and then the lower fixed shaft 720 is moved circumferentially so that the lower cover 220 and the upper cover 210 clamp the capacitor film 300.

[0045] In a specific embodiment, the capacitor film vacuum cutting device also includes: a base plate, which is a flat plate structure, and the upper fixing seat 110 and the lower fixing seat 120 are arranged on the base plate, and the plate surface of the upper fixing seat 110 and the lower fixing seat 120 are perpendicular to the plate surface of the base plate to ensure that the upper cover 210 and the lower cover 220 can be aligned.

[0046] In one specific embodiment, the capacitive film vacuum cutting device further includes two bearings, one disposed on the upper fixed seat 110 and the other on the lower fixed seat 120. The upper fixed shaft 710 is disposed within the bearing on the upper fixed seat 110, and the lower fixed shaft 720 is disposed within the bearing below the upper fixed seat 110. The upper fixed shaft 710 is positioned within the bearing on the upper fixed seat 110, providing stable support for the upper fixed shaft 710 and ensuring its stability and precision during rotation, thereby enabling the upper fixed shaft 710 to rotate circumferentially via the servo motor 500. Similarly, the lower fixed shaft 720 is disposed within the bearing on the lower fixed seat 120, enabling circumferential rotation and axial movement relative to the lower fixed seat 120.

[0047] In a specific embodiment, the bearing is a deep groove ball bearing.

[0048] The embodiments of the present application have been described above. The above description is illustrative and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
