Description

Technical Field

[0001] The utility model relates to the technical field of vacuum winding coating, in particular to a shielding oil evaporation system and vacuum winding coating equipment using the same. Background Art

[0002] The vacuum winding coating technology is to transfer the rolled film (such as PP, PET capacitor film) to the shielding oil evaporation device and the vacuum evaporation device in sequence through the winding device, and when the film passes through the shielding oil evaporation device during the transmission process, the shielding oil evaporation device evaporates the shielding oil to continuously perform oil film evaporation coating operations on the rolled film, that is, an oil film isolation layer is coated on a specific area on the base film surface of the film (a blank area where the deposited metal layer is not evaporated). After the oil film isolation layer is formed on the film surface, the winding device drives the film to the vacuum evaporation device, and the vacuum evaporation device performs an evaporation metal coating (deposit metal layer) operation on the area on the base film surface not covered by the oil film isolation layer.

[0003] At present, vacuum winding coating technology has been widely used in the manufacture of film capacitors in the fields of automobiles, industrial mother machines, packaging materials, large-scale mechanical equipment, etc., and the performance requirements for film capacitors in various fields are getting higher and higher, and the requirements for the thickness control flexibility and thickness uniformity of the oil film isolation layer on the surface of the capacitor film are also increasing. However, the traditional shielding oil evaporation device, whose oil film evaporation mechanism usually adopts a fixed setting method relative to the conveying path of the film, cannot accurately measure the relative position and distance between the oil film evaporation mechanism and the film, resulting in low installation accuracy of the oil film evaporation mechanism and uncontrollable distance between its evaporation hole and the film, which in turn causes the thickness of the oil film isolation layer formed by evaporation coating on the surface of the film base film to be uncontrollable, and the thickness of the oil film isolation layer formed on the surface is easily uneven due to the evaporation hole being too far away from the film, which affects the isolation and protection performance of the oil film isolation layer on the base film of the capacitor film, and thus affects the performance stability of subsequent film capacitor products.

[0004] Therefore, how to accurately adjust the distance between the shielding oil evaporation device and the film to accurately adjust the thickness of the oil film isolation layer on the film surface and improve the thickness uniformity of the oil film isolation layer is a technical problem that needs to be solved urgently in this field.

[0050] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-5 And embodiments, the utility model is further described in detail.

[0051] Please also read Figure 1-5 The shielding oil evaporation system provided by the utility model includes:

[0053] In this embodiment, the target film 2 is a metallized (metal-plated) capacitor film used in a film capacitor, such as a PP or PET capacitor film as the base film. Before the base film of the target film 2 is evaporated (evaporated) with a metal isolation layer by a vacuum winding coating device, the entire film surface of the base film of the target film 2 is isolated and divided into a plurality of areas of specified widths according to the technical index requirements of the film capacitor products of the downstream manufacturer, wherein the evaporation area for evaporating and depositing the metal layer and the blank area for coating the oil film isolation layer are arranged at staggered intervals. That is, the entire film surface of the base film of the target film 2 is arranged at intervals of a plurality of blank areas of specified widths, and an evaporation area of ​​specified width for evaporating and depositing the metal layer is formed between adjacent oil film isolation layers. The surface of the base film in the blank area needs to be pre-coated with a layer of oil film isolation layer to prevent metal deposition from occurring on the surface of the base film in the blank area in the subsequent vacuum evaporation process, so as to ensure the original performance of the base film in the blank area and avoid the film capacitor manufactured later from being affected by the intervention of metal materials in the blank area.

[0054] Please also read Figure 1-3 The shielding oil evaporation device 1 provided by the utility model is used to evaporate shielding oil to the target film 2, so as to form an oil film isolation layer by coating a plurality of blank areas of specified widths arranged at intervals on the surface of the base film of the target film 2, thereby forming a plurality of spaced-apart evaporation areas between the spaced-apart oil film isolation layers, so as to provide a subsequent vacuum evaporation process link for evaporating each evaporation area to form a deposited metal layer.

[0055] The shielding oil evaporation system provided by the utility model detects the real-time distance between the shielding oil evaporation device 1 and the target film 2 through the displacement sensor device 3, and can accurately determine the relative position and distance between the oil film evaporation mechanism and the target film 2, so that the control device can accurately calculate the displacement stroke of the shielding oil evaporation device 1 that needs to move closer to or away from the target film 2 linearly according to the real-time distance data fed back by the displacement sensor device 3, so that the real-time distance between the shielding oil evaporation device 1 and the target film 2 reaches a set distance (for better evaporation coating effect on the target base film), and control the linear drive device 4 to drive the shielding oil evaporation device 1 to move closer to or away from the target film 2 linearly with the calculated displacement stroke, so as to accurately adjust the real-time distance between the evaporation hole (not shown in the figure) of the shielding oil evaporation device 1 and the target film 2 to the set distance for better evaporation coating effect of the evaporation hole on the target base film.

[0056] Therefore, the shielding oil evaporation system provided by the utility model can achieve precise adjustment of the thickness of the oil film isolation layer formed by evaporation coating in the blank area on the base film surface of the target film 2, and improves the thickness uniformity of the oil film isolation layer formed in the blank area on the base film surface of the target film 2, so that the oil film isolation layer can effectively isolate and protect the base film of the target film 2 in the blank area, thereby ensuring the performance and quality stability of the oil film isolation layer of the target film 2, and thus meeting the performance requirements of subsequent film capacitor product manufacturing.

[0065] Through the bottom plate 51 in a horizontal posture and the pair of side plates 53 in a vertical posture, the bottom ends of the mounting vertical plates 4111 of the pair of racks 411 can be accurately and horizontally fitted with the top surface of the bottom plate 51, and the bottom ends of the reinforcing plates 4112 of the pair of racks 411 can be accurately and horizontally fitted with the top surface of the bottom plate 51, and at the same time, the two side ends of the pair of reinforcing plates 4112 can be vertically fitted with the two sets of mounting vertical plates 4111 and the side plates 53, so that the drive unit 412 and its drive line installed on the mounting vertical plates 4111 can be accurately and horizontally fitted.

[0066] The lifting parts of the linear transmission module 414 are driven by the driving unit 412 to vertically lift and lower the target film 2 below the conveying path A of the target film 2, thereby driving the lifting bracket 42 and the oil pipe 11 to lift and lower the target film 2 perpendicularly to the target film 2 and approach or move away from the target film 2 directly below the target film 2.

[0077] Please also read Figure 1-5 In this embodiment, the displacement sensor device 3 includes:

[0078] A pair of induction baffles 31 are respectively fixedly mounted on a pair of lifting brackets 42; as a preferred embodiment, the induction baffles 31 are preferably fixedly connected to the connecting vertical plate 421, and can also be fixedly connected to the horizontal carrier plate 422, and can also be fixedly connected to the support seat 423, or the induction baffles 31 can be fixedly connected between the connecting vertical plate 421, the horizontal carrier plate 422 and the support seat 423, or between any two of the three;

[0079] A pair of displacement sensor units 32 are respectively arranged at the two ends of the base 5 to match the pair of sensing baffles 31. The pair of displacement sensor units 32 are respectively used to sense the relative displacement of the pair of sensing baffles 31 (the relative position change of the sensing baffles 31 relative to the fixed sensing element of the displacement sensor unit 32 or the base 5), so that the control device calculates the above-mentioned real-time distance according to the relative displacement of the sensing baffles 31 and the preset height of the target film 2 (the transmission path of the target film 2 passes through the top of the base 5 and the preset distance between the fixed sensing element of the displacement sensor unit 32 or the base 5).

[0080] Since the shielding oil evaporation device 1 is provided with an induction baffle 31, a displacement sensor unit 32 and a linear drive mechanism 41 at both axial ends, the axial heights of the oil pipe 11 of the shielding oil evaporation device 1 (the distance from the target film 2) can be adjusted synchronously to ensure that the shielding oil evaporation device 1 keeps the oil pipe 11 in an overall axial horizontal state during the lifting process, avoiding the situation where the axial heights of the two ends of the oil pipe 11 and the distances from the target film 2 are inconsistent after the lifting and lowering adjustment, thereby ensuring the uniformity of the oil film isolation layer formed by the subsequent evaporation coating of the target film 2.

[0081] Please also read Figure 1-3 5. In this embodiment, the displacement sensor unit 32 is a telescopic displacement sensor unit 32, and the telescopic displacement sensor unit 32 is connected to the sensing baffle 31 through its sensing telescopic rod 321. As a preferred embodiment, the sensing telescopic rod 321 of the telescopic displacement sensor unit 32 extends vertically and is vertically connected to the horizontal sensing baffle 31, so that the distance detection direction of the displacement sensor device 3 and the linear motion direction of the linear drive device 4 driving the shielding oil evaporation device 1 to approach or move away from the target film 2 are consistent (both are vertical lifting), further improving the accuracy of the displacement sensor device 3 in measuring the above real-time distance.

[0082] In other embodiments, the displacement sensor unit 32 may also be a photoelectric displacement sensor unit 32 , and the photoelectric displacement sensor unit 32 detects the relative displacement of the sensing baffle 31 through an optical signal.

[0083] Please also read Figure 1-3 In this embodiment, the oil pipe 11 includes:

[0084] Tube body 111; oil delivery channel (not shown in the figure), which is arranged in the tube body 111, and the oil delivery channel forms an oil delivery hole 113 at the top of one end of the tube body 111; multiple annular protrusions 112 are arranged at intervals in the axial direction of the tube body 111, and each annular protrusion 112 is arranged around the outer surface of the tube body 111 along the circumference of the tube body 111, and the evaporation hole is arranged in the part of the annular protrusion 112 facing the upper target film 2, and is connected to the oil delivery channel. Therefore, the projection area of ​​the base film surface of the annular protrusion 112 facing the upper target film 2 is the blank area, and the projection area of ​​the outer surface of the tube body 111 between adjacent annular protrusions 112 facing the base film surface of the upper target film 2 is the evaporation area.

[0085] Since the evaporation holes are only arranged on the portion of the annular protrusions 112 arranged at intervals facing the upper target film 2, the annular protrusions 112 arranged at intervals in the axial direction of the tube body 111 can firstly play a role in positioning the blank areas on the base film surface of the target film 2. The shielding oil evaporation device 1 only evaporates and coats the projection areas (blank areas) of the base film surface of the upper target film 2 facing the annular protrusions 112 to form an oil film isolation layer, while no evaporation holes are arranged on the projection areas of the base film surface of the upper target film 2 at adjacent positions between the annular protrusions 112, so that no oil film isolation layer is formed in the adjacent areas (evaporation areas) between the blank areas on the base film surface of the target film 2, so that the various evaporation areas on the base film surface of the target film 2 can be subsequently evaporated to form a deposited metal layer.

[0086] Secondly, to ensure that an oil film isolation layer is formed by evaporation coating on the base film surface of the target film 2, when the shielding oil evaporation system is in use, the target film 2 and the tube body 111 of the oil tube 11 need to be kept at a close distance. Therefore, when the target film 2 is wound along the conveying path A above the shielding oil evaporation device 1 under the drive of the winding device, it is easy for the target film 2 to shake and twist. During the shaking and twisting process, the target film 2 is prone to get close to or even directly touch the evaporation holes on the tube body 111 over a large area, thereby causing the shielding oil vapor evaporated from the evaporation holes to contaminate the evaporation area adjacent to the blank area on the base film surface of the twisted and deformed target film 2, and form an oil film isolation layer in the evaporation area, affecting the performance and yield of the target film 2. Since the shielding oil evaporation device 1 provided by the utility model has the annular protrusions 112 spaced apart in the axial direction of the tube body 111, the target film 2 may only touch the annular protrusions 112 on the tube body 111 during the shaking process. On the one hand, the degree of distortion of the target film 2 during the shaking process is limited. On the other hand, the target film 2 is prevented from being too close to or directly contacting the evaporation hole in its evaporation area due to distortion during the shaking process. This ensures that even if the target film 2 touches the annular protrusions 112 during the shaking process, only an oil film isolation layer will be formed in its blank area, thereby ensuring that the evaporation of the shielding oil will not pollute its evaporation area, thereby improving the performance and yield of the target film 2.
