[0041] like Figure 1 and Figure 2As shown, the capacitor film vacuum gauge cutting device of the embodiment of the present application includes: an upper cover 210, a lower cover 220, a capacitor film 300, a fixed seat, a fixed shaft and a turning tool 800. There are two fixed shafts, including a first fixed shaft 720 and a second fixed shaft 710. The first fixed shaft 720 and the second fixed shaft 710 are respectively rotatably arranged on the fixed seat, and the first fixed shaft 720 is coaxially arranged with the first fixed shaft 720. The upper cover 210 is arranged at one end of the axial length direction of the first fixed shaft 720, and the lower cover 220 is arranged at one end of the axial length direction of the second fixed shaft 710. The upper cover 210 corresponds to the lower cover 220. The turning tool 800 is arranged on the fixed seat, adjacent to the edge position of the upper cover 210 and the lower cover 220, and the capacitor film 300 is clamped between the upper cover 210 and the lower cover 220. The fixed shaft rotates relative to the turning tool 800 to turn the excess part of the capacitor film 300 relative to the upper cover 210 and the lower cover 220.

[0042] 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 second 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 cover 210 and the lower cover 220 clamp a larger capacitor film 300 in a closed state, the turning tool 800 is set on a fixed seat, and the cutting position of the turning tool 800 is close to the abutment position of the upper cover 210 and the lower cover 220. By rotating the second fixed shaft 710, the excess part 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 redundant existence of the capacitor film 300 relative to the upper cover 210 and the lower cover 220, and it is more convenient to operate on the capacitor film 300 clamped by the upper cover 210 and the lower cover 220.

[0043] In this embodiment, the device is mainly composed of an upper cover 210, a lower cover 220, a capacitor film 300, a fixed seat, a first fixed shaft 720, a second fixed shaft 710 and a turning tool 800. The first fixed shaft 720 and the second fixed shaft 710 are rotatably arranged on the fixed seat. The first fixed shaft 720 and the second fixed shaft 710 are not only rotatable, but also coaxially arranged. At one end in the axial length direction, the first fixed shaft 720 is connected to the upper cover 210, and the axial length end of the second fixed shaft 710 is connected to the lower cover 220. The upper cover 210 and the lower cover 220 correspond to each other to form a clamping space. The turning tool 800 is a processing tool for the capacitor film 300, and is arranged on the fixed seat near the edges of the upper cover 210 and the lower cover 220 to ensure the accuracy of the turning operation. The capacitor film 300 is clamped between the upper cover 210 and the lower cover 220 . As the fixed shaft rotates relatively, the turning tool 800 begins to play its role and cuts off the redundant part of the capacitor film 300 relative to the upper cover 210 and the lower cover 220 .

[0044] When the cutting tool 800 cuts off the excess portion of the capacitor film 300, the cutting tool 800 remains stationary and the second fixed shaft 710 rotates circumferentially. Since the cutting tool 800 is close to the connection edge of the upper cover 210 and the lower cover 220 that clamp the capacitor film 300, the upper cover 210, the capacitor film 300 and the lower cover 220 are driven to rotate circumferentially by the second fixed shaft 710, thereby cutting off the excess portion of the capacitor film 300 relative to the upper cover 210 and the lower cover 220.

[0045] It should be noted that when the upper cover 210 and the lower cover 220 are in contact, the edge position of the upper cover 210 is aligned with the edge position of the lower cover 220 .

[0046] In a specific embodiment, the capacitor film vacuum gauge cutting device 10 also includes: a first bearing seat and a first bearing, the first bearing seat is arranged on the first fixed seat 120, and the first bearing is arranged inside, and the first fixed shaft 720 is installed in the first bearing and can slide axially. In this way, the first fixed shaft 720 can not only rotate on the fixed seat, but also slide axially, so as to facilitate the adjustment of the clamping force between the upper cover 210 and the lower cover 220, and ensure that the capacitor film 300 is stably clamped. Among them, the first bearing seat is cleverly arranged on the fixed seat, and a precise space is reserved inside it for installing the first bearing. This design enables the first fixed shaft 720 to rotate on the fixed seat in a more stable and flexible manner. The design of the bearing seat not only ensures the stable installation of the bearing, but also provides the necessary support and stability for the entire cutting device through its sturdy structure.

[0047] In this specific embodiment, the first bearing is used as a component connecting the first fixed shaft 720 and the first bearing seat. The first bearing is made of a material with wear resistance and corrosion resistance to ensure that the first bearing maintains stable performance under high-speed rotation. When the first fixed shaft 720 rotates in the bearing, it can rotate along the circumferential direction without being subjected to excessive friction and resistance, so that the second fixed shaft 710 can drive the upper cover 210, the lower cover 220 and the first fixed shaft 720 to rotate around the circumferential direction in turn. Among them, the first fixed shaft 720 can also slide along the axial direction, which is convenient for adjusting the clamping force and position between the upper cover 210 and the lower cover 220. By fine-tuning the position of the first fixed shaft 720, it can be ensured that the capacitor film 300 is evenly and stably clamped between the upper cover 210 and the lower cover 220, thereby avoiding cutting errors caused by unstable clamping.

[0048] Further, in a specific embodiment, the fixing seat includes a first fixing seat 120 and a second fixing seat 110, both of which are plate-shaped structures and are vertically arranged. A preset distance is provided between the vertically arranged first fixing seat 120 and the vertically arranged second fixing seat 110, so as to facilitate the placement of the upper cover 210 and the lower cover 220, and to operate the turning tool 800 to turn the excess part of the capacitor film 300.

[0049] The first fixed seat 120 is provided with a first bearing mounting hole, and the second fixed seat 110 is provided with a second bearing mounting hole. The first fixed shaft 720 is installed in the first bearing mounting hole of the first fixed seat 120 through the first bearing, and the second fixed shaft 710 is installed in the second bearing mounting hole of the second fixed seat 110 through the second bearing. The first bearing mounting hole is coaxially arranged with the second bearing mounting hole. After the first fixed shaft 720 and the second fixed shaft 710 are both installed, the first fixed shaft 720 can be coaxially arranged with the second fixed shaft 710, thereby facilitating the subsequent abutment and alignment of the upper cover 210 and the lower cover 220. It should be noted that the outer layer of the bearing is connected to the fixed seat bolts.

[0050] In a specific embodiment, a first fixing groove is opened at one end of the first fixing shaft 720 adjacent to the second fixing shaft 710, and the upper cover 210 is embedded in the first fixing groove. A second fixing groove is opened at one end of the second fixing shaft 710 adjacent to the first fixing shaft 720, and the lower cover 220 is embedded in the third fixing groove.

[0051] Among them, the first fixed shaft 720 is provided with a first fixing groove at one end adjacent to the second fixed shaft 710, and the upper cover 210 is embedded in the first fixing groove. The second fixed shaft 710 is provided with a second fixing groove at one end adjacent to the first fixed shaft 720, and the lower cover 220 is embedded in the second fixing groove. By providing the fixing groove, it can be ensured that the upper cover 210 and the lower cover 220 are stably fixed on the fixed shaft to avoid shaking or falling off during the cutting process. Specifically, since the first fixed shaft 720 and the second fixed shaft 710 are coaxially arranged, the first fixing groove corresponds to the second fixing groove. When the upper cover 210 is installed in the matching first installation groove and the lower cover 220 is installed in the matching second installation groove, the upper cover 210 and the lower cover 220 can be completely abutted and aligned by sliding the first fixing shaft 720 in the axial direction. The cross-section of the upper cover 210 is circular, so the corresponding first installation groove is a groove structure with a circular cross-section, which is used to install and fix the upper cover 210.

[0052] In a specific embodiment, the capacitor film vacuum gauge cutting device 10 also includes: a torque wrench 400, which is arranged on the first bearing seat and connected to the first fixed shaft 720. The torque wrench 400 is rotated to drive the first fixed shaft 720 to move toward the second fixed shaft 710, and the upper cover 210 and the lower cover 220 are tightened to clamp the capacitor film 300. Through the torque wrench 400, the distance between the lower cover 220 and the upper cover 210 and the clamping force between the upper cover 210 and the lower cover 220 can be easily adjusted to ensure that the capacitor film 300 is clamped evenly and stably.

[0053] Specifically, it also includes: a slider, a gasket and a fixing nut, which are sequentially installed in the first bearing seat.

[0054] In a specific embodiment, the capacitor film vacuum gauge cutting device 10 also includes: a base plate 100 and a tool holder 900, the base plate 100 is a plate-like structure with a flat surface, the fixed seat is fixed on the base plate 100, the tool holder 900 is arranged on the base plate 100, and the tool holder 900 clamps the turning tool 800 and can move on the base plate 100 along the direction perpendicular to the fixed axis and parallel to the fixed axis. By adjusting the position of the tool holder 900, the capacitor film 300 can be cut at different positions, thereby improving the flexibility and accuracy of cutting.

[0055] Furthermore, in this specific embodiment, the bottom plate 100 is a plate-shaped plate with a flat surface and uniform structure, which provides a stable basic platform to ensure the stability and accuracy of the entire cutting device. The tool holder 900 enables the turning tool 800 to be installed in a position during the cutting process. Among them, the tool holder 900 can move in multiple dimensions on the bottom plate 100. The tool holder 900 can move in a direction perpendicular to the fixed axis, which helps to adjust the depth or angle of the cutting. At the same time, it can also move in a direction parallel to the fixed axis to adjust the edge of the connection position between the turning tool 800 and the upper cover 210 and the lower cover 220, which greatly enhances the accuracy and efficiency of the cutting.

[0056] Specifically, Figure 3 As shown, the tool holder 900 includes: a sliding part 910, a fixing part 930 and a clamping part 940. The fixing part 930 is fixedly installed on the plate surface of the bottom plate 100, located between the first fixing seat 120 and the second fixing seat 110, and the fixing part 930 is a block structure with a preset thickness and length, and a sliding groove with a preset length is provided at the top, and the length direction of the sliding groove is the same as the axial length direction of the fixed shaft. The sliding part 910 is slidably arranged on the fixing part 930, and is slidably arranged on the top of the fixing part 930 through a sliding block 920. The sliding block 920 is a plate-like structure, and a sliding bolt is provided through it. The sliding bolt is located inside the sliding groove and can slide relative to the axial length direction of the fixed shaft, and can be fixed by a nut and the sliding bolt. When the sliding block 920 slides to the connection position between the upper cover 210 and the lower cover 220, the nut is used to fix it. The clamping portion 940 is slidably arranged on the top of the fixing portion 930, and can be fixed after sliding in the horizontal direction along the direction of the vertical fixing axis relative to the fixing portion 930. The overall cross-section of the clamping portion 940 is an "I" shape, and the hollow space uses bolts to clamp the turning tool 800.

[0057] Specifically, the clamping part 940 includes: a clamping bottom plate 941, a clamping support part 942 and a clamping top plate 943, wherein the clamping support part 942 is located between the clamping top plate 943 and the clamping bottom plate 941 to support the clamping top plate 943. The turning tool 800 is placed between the clamping bottom plate 941 and the clamping top plate 943, and a plurality of bolts are passed through the clamping top to fasten the turning tool 800.

[0058] According to the above content, the device is prepared as follows: ensure that the bottom plate 100 is fixed and the plate surface is flat, providing a stable basic platform for the entire cutting device, and the fixed seat has been firmly installed on the bottom plate 100 to provide necessary support for the cutting process. Installation and adjustment of the tool holder 900: install the fixed part 930 of the tool holder 900 on the plate surface of the bottom plate 100, and ensure that it is located between the first fixed seat 120 and the second fixed seat 110. The fixed part 930 should be a block structure with a preset thickness and length, and a sliding groove with a preset length is opened on the top, and the sliding block 920 is slidably set on the sliding groove of the fixed part 930. The sliding block 920 is a plate-like structure, and a sliding bolt is penetrated inside. The bolt can slide in the sliding groove along the axial length direction of the fixed axis. By adjusting the position of the sliding block 920, it slides to the connection position between the upper cover 210 and the lower cover 220, and the sliding bolt is fixed with a nut, thereby determining the starting position of the cutting. Installation of the turning tool 800: The clamping part 940 includes a clamping bottom plate 941, a clamping support part 942 and a clamping top plate 943. The clamping part 940 is slidably arranged on the top of the fixed part 930, and it can slide in the horizontal direction along the direction of the vertical fixed axis relative to the fixed part 930. The turning tool 800 is placed between the clamping bottom plate 941 and the clamping top plate 943 to ensure that the position of the turning tool 800 is accurate. A plurality of bolts are passed through the clamping top, and the turning tool 800 is fastened in the clamping part 940 using these bolts. Cutting operation: According to the position and size of the capacitor film 300 to be cut, the position of the tool holder 900 is adjusted. This includes adjusting the cutting depth or angle in a direction perpendicular to the fixed axis, and adjusting the edge of the connection position of the turning tool 800 with the upper cover 210 and the lower cover 220 in a direction parallel to the fixed axis. When the position of the tool holder 900 and the turning tool 800 is adjusted, the cutting device is started to make the turning tool 800 cut the capacitor film 300 along a predetermined path.

[0059] In a specific embodiment, it also includes: a servo motor 500 and a coupling. The servo motor 500 is arranged on the base plate 100. The servo motor 500 is connected to the second fixed shaft 710 through the coupling to drive the second fixed shaft 710 to rotate circumferentially. The drive of the servo motor 500 can realize precise rotation of the fixed shaft, thereby ensuring the stability and accuracy of the cutting process.

[0060] Furthermore, in this specific embodiment, it also includes: a motor seat, which is arranged on the bottom plate 100 and is adjacent to the second fixed seat 110. The servo motor 500 is installed on the motor seat, and the output shaft of the servo motor 500 is coaxially arranged with the second fixed shaft 710. The output shaft of the servo motor 500 is connected to the second fixed shaft 710 through a coupling, and drives the second fixed shaft 710, the upper cover 210 and the lower cover 220 to rotate circumferentially in turn, and then the turning tool 800 is used for turning.

[0061] In a specific embodiment, the diameter of the capacitor film 300 is larger than the cross-sectional diameter of the upper cover 210 and 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 second fixed shaft 710 is moved circumferentially so that the lower cover 220 and the upper cover 210 clamp the capacitor film 300. Specifically, since the cross-section of the capacitor film 300 must be the same as the connection position of the upper cover 210 and the lower cover 220, it is not convenient to clamp the capacitor film 300 between the upper cover 210 and the lower cover 220. In the present application, the capacitor film 300 can be manually held and clamped between the upper cover 210 and the lower cover 220, and then the excess part of the capacitor film 300 relative to the upper cover 210 can be cut off.

[0063] In this specific embodiment, an intelligent welding device is used to improve the welding effect of the upper cover 210, the capacitor film 300 and the lower cover 220, thereby ensuring the overall yield rate.

[0064] Specifically, the welding device includes two parts, mechanical arms 21 and 22, wherein 22 is arranged at the free end of the mechanical arm 21, and the welding of the upper cover 210, the capacitor film 300 and the lower cover 220 is completed through the preset program of the mechanical arm 21. The preset program of the mechanical arm 21 is a step of obtaining a certain size or specification through multiple tests.

[0065] In a specific embodiment, a detection device is also provided at the free end of the robotic arm 21. The detection device may be an ultraviolet device for detecting the welding conditions of the upper cover 210, the capacitor film 300 and the lower cover 220. When bubbles appear in the welding, the welding can be stopped in time to ensure the product yield.

[0066] In a specific embodiment, the automatic welding control system further includes: a display device 30, which is in communication with the welding device to obtain parameters of the welding device and regulate the welding device.

[0067] A method for cutting and welding a capacitor film 300, using an automatic welding control system, comprises the following steps in sequence:

[0068] S100, the upper cover 210 and the lower cover 220 clamp the capacitor film 300;

[0069] In this step, the first fixed shaft 720 and the second fixed shaft 710 are rotatably arranged on the fixed seat. The first fixed shaft 720 and the second fixed shaft 710 are not only rotatable, but also keep a coaxial arrangement therebetween. At one end in the axial length direction, the first fixed shaft 720 is connected to the upper cover 210, and the axial length end of the second fixed shaft 710 is connected to the lower cover 220.

[0070] S200, rotating the upper cover 210 or the lower cover 220, and using the turning tool 800 to turn the redundant portion of the capacitor film 300 relative to the upper cover 210 and the lower cover 220;

[0071] In this step, the fixing part 930 of the tool holder 900 is installed on the surface of the base plate 100, and ensures that it is located between the first fixing seat 120 and the second fixing seat 110. The fixing part 930 should be a block structure with a preset thickness and length, and a sliding groove of a preset length is opened on the top. The sliding block 920 is slidably set on the sliding groove of the fixing part 930. The sliding block 920 is a plate-like structure, and a sliding bolt is passed through the inside.
