[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment, according to Figure 1 - Figure 8 ,like Figure 1 As shown, a capacitor winding machine with a film deviation correction function provided by an embodiment of the present invention includes a material unwinding disk mechanism 1, a tension mechanism 11, a pressure wheel mechanism 12, a winding mechanism 13, a core delivery mechanism 14, a flattening mechanism 15 and a conveyor belt 16, as shown in FIG. Figure 2In the embodiment, the unwinding material disk mechanism 1 includes a supporting plate 2, on which an unwinding film disk 23 is installed, and the upper and lower sides of the supporting plate 2 are respectively slidably connected with a loading disk 21 and a chassis 22, and a correction driver 24 is installed between the supporting plate 2 and the loading disk 21 and the chassis 22, and a roller 1 3 is installed on the supporting plate 2, and a roller 2 31 is installed on the loading disk 21 and the chassis 22, and a correction sensor 4 is arranged between the two rollers 2 31 and the roller 1 3, and the two correction sensors 4 are respectively installed on the supporting plate 2 and the chassis 22, such as Figure 5 In the embodiment, the deflection correction sensor 4 installed on the support plate 2 is also provided with a covering structure 6 for adjusting the monitoring range. The unwinding material disc mechanism 1 can compensate for the offset of the film winding in two times. The deflection correction sensor 4 installed on the support plate 2 detects the film offset for the first time. Since the detection range of the deflection correction sensor 4 is limited by the covering structure 6, the coverage range of the covering structure 6 is a controllable variable, that is, the deflection correction sensor 4 can be limited to detect only the offset beyond the coverage range. After the deflection correction driver 24 between the support plate 2 and the loading plate 21 is controlled to drive the unwinding film disc 23 to move, when the loading plate 21 moves with the unwinding film disc 23, since the roller 3 and the deflection correction sensor 4 installed on the support plate 2 are fixed in position, the unwinding film disc 23 is released. The film is displaced on roller one 3, and the first offset compensation is performed to correct the film offset in a small range. The film continues to be transmitted, and the film offset is detected for the second time by the correction sensor 4 installed on the chassis 22, and the correction driver 24 between the support plate 2 and the chassis 22 is controlled to operate, so that the support plate 2, the loading plate 21, and the unwinding film plate 23 are relatively stationary. The film released by the unwinding film plate 23 is relatively displaced with the roller two 31 on the chassis 22 through the transmission of roller one 3, and the second offset compensation is performed to correct the film offset. The correction process for the film with a large offset is divided into two steps for offset compensation, so that the deviation can be corrected in time when the capacitor core is wound at high speed, and the compensation displacement is prevented from being too large, causing the adverse effect of secondary offset on the film that has been corrected at the front end.

[0023] like Figure 3 , Figure 5 , Figure 6 and Figure 7In the embodiment, the covering structure 6 includes two sliding covers 61, one of the sliding covers 61 is slidably sleeved on the outer side wall of the other sliding cover 61, and the other sliding cover 61 is slidably sleeved on the inner side wall of the deviation correction sensor 4. The two sliding covers 61 jointly cover the middle position of the inner side of the deviation correction sensor 4, and a threaded feed rod 62 is threadedly sleeved between the two sliding covers 61. The threaded feed rod 62 is rotatably connected to the outer side wall of the deviation correction sensor 4 and is provided with a rotating handle at one end. The two sliding covers 61 jointly slidably sleeved with a threaded feed rod 62. The slide bar 65 is fixedly connected to the outer wall of the deviation correction sensor 4. By controlling the rotation of the threaded feed rod 62, the threaded feed slide cover 61 can be slid on the slide bar 65, and the slide cover 61 is adjusted to cover the monitoring range of the deviation correction sensor 4, so as to control the range of the first detection of film deviation; the deviation correction sensor 4 installed on the support plate 2 is provided with two pairs of optical signal monitoring windows, and the two pairs of optical signal monitoring windows are respectively located on both sides of the film. The two pairs of optical signal monitoring windows are provided to monitor the film deviation to the inside or outside; Figure 5 In the figure, a scale mark 63 is provided below the sliding cover 61, and the scale mark 63 is provided on the outer side wall of the correction sensor 4. A pointer 64 is fixedly connected to the bottom end of the sliding cover 61, and is used to adjust the coverage range of the sliding cover 61 by the scale mark 63 and the pointer 64 for precise adjustment; like Figure 2 , Figure 3 and Figure 4 In the embodiment, the carrier plate 21 is installed with a slider fixing plate 5, an unwinding servo motor 53 and a tightening cylinder 54, the slider fixing plate 5 is installed with a bearing seat 56, an inflatable shaft 55 is installed inside the bearing seat 56, the unwinding film plate 23 is installed at one end of the inflatable shaft 55, the other end of the inflatable shaft 55 is movably connected to the tightening cylinder 54, the unwinding servo motor 53 is transmission-connected to one end of the inflatable shaft 55, and the carrier plate 21 is connected to the roller 2 31 through the slider fixing plate 5; Figure 2 The upper surfaces of the support plate 2 and the chassis 22 are respectively fixed with a primary slide rail 51 and a secondary slide rail 52, the loading tray 21 is slidably connected to the support plate 2 via the primary slide rail 51, and the support plate 2 is slidably connected to the chassis 22 via the secondary slide rail 52, so as to stabilize the sliding direction of the support plate 2, the loading tray 21, and the chassis 22 when they are relatively displaced; A side mounting frame 32 is fixedly connected to one side of the support plate 2, and the support plate 2 is fixedly connected to the roller 1 3 and the deviation correction sensor 4 through the side mounting frame 32. The roller 1 3 and the deviation correction sensor 4 are installed on the side mounting frame 32 and are located on one side of the unwinding film disk 23, so that the space is reasonably used and the structure is stable. A plurality of rollers 111 for limiting the film transmission path are arranged between the unwinding material disc mechanism 1, the tension mechanism 11, the pressure wheel mechanism 12 and the winding mechanism 13, and are used to limit the film material transmission path a; Figure 1 In the embodiment, four unwinding material disc mechanisms 1 are provided, including a material disc mechanism 101, a material disc mechanism 2 102, an inner material disc mechanism 103 and an outer material disc mechanism 104. The material disc mechanism 101 and the material disc mechanism 2 102 are used to place the metallized film synchronously, the inner material disc mechanism 103 is used to place the inner film, and the outer material disc mechanism 104 is used to place the outer film. The winding mechanism 13 includes a turning shaft 131 and a work station 132. The turning shaft 131 is used to drive the work station 132 to rotate. The position of the work station 132 is changed to wind the inner lining, the capacitor core and the outer layer of the capacitor core.

[0024] In this embodiment, the capacitor core is firstly wound with the inner film released by the outer material disc mechanism 104 at the workstation 132 to form the inner lining of the capacitor core; then the material disc mechanism 101 and the material disc mechanism 2 102 simultaneously release the metallized film along the material film path through the roller 2 31 on the bearing seat 56, the correction sensor 4 and roller 1 3 on the side mounting frame 32, the correction sensor 4 and roller 2 31 on the chassis 22, the roller 111 and the tension mechanism 11, and is wound into the capacitor core in the workstation 132; the outer film released by the outer material disc mechanism 104 is wrapped around the outer layer of the capacitor core in the workstation 132 to form the outer layer; then, the core is sent to the bottom of the flattening mechanism 15 by the core conveying mechanism 14 for pre-flattening. Finally, the core is sent to the next process by the conveyor belt 16.

[0025] like Figure 8 As shown, this is a system feedback diagram of the deflection correction driver 24 and the deflection correction sensor 4. The set value of the film position and the feedback value transmitted from the deflection correction sensor 4 are processed by the PLC and then output as a control quantity to the deflection correction driver 24. The deflection correction driver 24 controls the front and rear positions of the unwinding film disk 23 to control the position of the unwinding film. The disturbance quantity is affected by factors such as the installation position of the unwinding film disk 23 not being parallel to the support plate 2 and the verticality of the roller 111.

[0026] like Figure 7The figure shows a detection schematic diagram of the deflection correction sensor 4, which is used to detect the position and offset of the film. The rapid and accurate detection of the offset during the film conveying process is the prerequisite for ensuring the normal operation of the deflection correction compensation offset; the light signal is emitted from the upper window of the sensor and returned through the lower receiving window, and the size and position of the detected object are judged according to the width of the returned light signal; when there is no obstruction in the U-shaped groove of the sensor, the light signal emitted by the upper window is almost completely received by the lower receiving window, and we can consider that the light receiving intensity at this time is 100%, and the corresponding output voltage is +10 V; on the contrary, when the receiving window on the lower side of the U-shaped groove is completely blocked and there is no light signal, the light receiving intensity at this time is 0, and the corresponding output voltage is 0 V; The position of the film in the U-shaped groove of the sensor is different, the light transmittance is different, and the corresponding output voltage Ui is also different; the inner edge of the film is set in the middle position of the sensor light signal, and the output voltage U0 = +5V at this time; the width of the sensor light signal is set to S, and the system correction accuracy is ±δmm. When the sensor output voltage Ui >U0 + (10δ / S), it means that the film is offset to the outside, and the correction driver 24 is required to drive the unwinding film disk 23 to move inward to the corresponding compensation position; when the sensor output voltage Ui <U0 - (10δ / S), it means that the film is offset to the inside, and the correction driver 24 is required to drive the unwinding film disk 23 to move outward to the corresponding compensation position; when the sensor output voltage U0 - (10δ / S) ≤ Ui ≤ U0 + (10δ / S), it means that the film offset is within the system correction range, and there is no need to move the correction driver 24; (It should be noted that the setting of the covering structure 6 and the design of the deflection correction sensor 4 on the side mounting frame 32, the deflection correction sensor 4 installed on the unwinding film disc 23 is suitable for monitoring the situation when the film material deflects greatly, and the deflection correction sensor 4 installed on the unwinding film disc 23 is provided with a set of upper and lower windows on both sides of the film, and its working principle is basically the same as the above, the difference is that when the voltage output by the sensor on one side decreases, the deflection correction driver 24 is controlled to push the unwinding film disc 23 to move to the opposite side to perform the first offset compensation, the purpose is to, through the sliding cover 6 1 covers a certain area of ​​the optical signal emission window of the correction sensor 4 on the side mounting frame 32 to limit the detection range of the optical signal on the correction sensor 4. When the film deflection exceeds the range, the correction driver 24 is controlled to drive the loading plate 21 to slide on the support plate 2, and the unwinding film plate 23 and the roller 2 31 located above move relative to the roller 1 3 to compensate for the deviation of the material film beyond the coverage range of the covering structure 6. When the sensor output voltage is stable, it means that the film deviation does not need a large displacement compensation, and the deviation compensation is performed when the film deviation is detected for the second time).

[0027] In this embodiment, in the process of correcting the deviation of the winding capacitor core, when the unwinding film disk 23 releases the material film and passes through the roller 2 31 and roller 1 3 located above, the correction sensor 4 installed on the side mounting frame 32 performs the first detection of the deviation of the material film, and covers the optical signal emission windows on the inner and outer sides of the material film by two sliding covers 61, thereby limiting the detection range of the correction sensor 4, and the side beyond the coverage of the sliding cover 61 further blocks the irradiation of this side light signal, so that the output voltage of the correction sensor 4 is reduced, and the correction driver 24 between the support plate 2 and the loading plate 21 is controlled by PLC. The output end of the correction driver 24 drives the unwinding film disk 23 to move to the opposite side by pushing the bearing seat 56, thereby performing the first compensation for the deviation of the material film; the material film continues to be transmitted, passes through roller 1 3 and roller 2 31 installed on the chassis 22 During the process, the deviation correction sensor 4 installed on the chassis 22 performs a second detection on the offset of the material film, and controls the deviation correction driver 24 between the support plate 2 and the chassis 22 through the PLC to drive the support plate 2 to move along the secondary slide rail 52 on the chassis 22. When the support plate 2 moves on the chassis 22, the support plate 2 and the loading plate 21 are relatively stationary, so that the unwinding film plate 23 and the roller 1 3 are relatively displaced with the roller 2 31 installed on the chassis 22 to compensate for the offset of the material film, and correct the offset of the material film in time. The deviation correction process runs stably, and when the capacitor core is wound at high speed, the end surface flatness of the capacitor core is improved. When the material film has a large offset, the first and second offset compensations are performed, which effectively avoids excessive deviation correction action, causing the material film on the front-end transmission path to be disturbed and have a secondary offset, so that the effect of improving the end surface flatness of the capacitor core remains stable.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
