Description

[0001] The present invention relates to the technical field of capacitor winding machines, and in particular to a capacitor winding machine with a film deviation rectification function. Background Art

The unwinding material disk mechanism includes a support plate, on which an unwinding film disk is installed. The upper and lower sides of the support plate are respectively slidably connected with a carrier disk and a chassis. Deviation rectification drivers are installed between the support plate and the carrier disk and the chassis. A first roller is installed on the support plate, and second rollers are installed on both the carrier disk and the chassis. Deviation rectification sensors are arranged between the two second rollers and the first roller, and the two deviation rectification sensors are respectively installed on the support plate and the chassis. The deviation rectification sensor installed on the support plate is also provided with a covering structure for adjusting the monitoring range. The unwinding material disk mechanism can compensate the offset of film winding in two times.

[0006] In at least some embodiments, the covering structure includes two sliding covers, one of which is slidably sleeved on the outer wall of the other sliding cover, and the other sliding cover is slidably sleeved on the inner wall of the correction sensor. The two sliding covers jointly cover the middle position of the inner side of the correction sensor, and a threaded feed rod is threadedly sleeved between the two sliding covers. The threaded feed rod is rotatably connected to the outer wall of the correction sensor and is provided with a rotating handle at one end thereof. A sliding rod is slidably sleeved between the two sliding covers, and the sliding rod is fixedly connected to the outer wall of the correction sensor.

[0007] In at least some embodiments, the deviation correction sensor installed on the support plate is provided with two pairs of optical signal monitoring windows, and the two pairs of optical signal monitoring windows are respectively located on two sides of the film.

[0008] In at least some embodiments, a scale mark is provided below the sliding cover, the scale mark is arranged on the outer side wall of the deviation correction sensor, and a pointer is fixedly connected to the bottom end of the sliding cover.

[0009] In at least some embodiments, a slider fixing plate, an unwinding servo motor and an expansion cylinder are installed on the loading plate, a bearing seat is installed on the slider fixing plate, an inflatable shaft is installed inside the bearing seat, the unwinding film disk is installed at one end of the inflatable shaft, the other end of the inflatable shaft is movably connected to the expansion cylinder, the unwinding servo motor is transmission-connected to one end of the inflatable shaft, and the loading plate is connected to roller two via the slider fixing plate.

[0010] In at least some embodiments, the upper surfaces of the support plate and the chassis are respectively fixed with a primary slide rail and a secondary slide rail, the loading tray is slidably connected to the support plate via the primary slide rail, and the support plate is slidably connected to the chassis via the secondary slide rail.

[0011] In at least some embodiments, a side mounting frame is fixedly connected to one side of the support plate, and the support plate is fixedly connected to roller 1 and the deviation correction sensor via the side mounting frame.

[0012] In at least some embodiments, four unwinding material tray mechanisms are provided, including a material tray mechanism 1, a material tray mechanism 2, an inner material tray mechanism, and an outer material tray mechanism.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] 1. In the present invention, during the process of winding the capacitor core, the unwinding material disk mechanism is set. During the process of releasing the winding material, the deviation correction sensor is set to monitor the feedback data of the film position to control the deviation correction driver to drive the unwinding film disk to move, compensate for the offset of the film, timely correct the offset of the winding material, improve the end surface flatness of the wound capacitor core, and the deviation correction effect is stable.

[0017] 2. In the present invention, since the material film is in a high-speed transmission environment and passes through multiple rollers in its transmission path, the deviation correction sensor on the side mounting frame first detects the offset of the material film. The set covering structure covers a fixed area, and only the offset beyond the covered range is detected. The deviation correction driver controls the carrier plate to move on the support plate to adjust the relative position of the unwinding film disk and the first roller, and compensates for the offset for the first time. The deviation correction sensor on the chassis secondarily detects the offset of the material film. The deviation correction driver controls the support plate to move on the chassis to adjust the relative positions of the unwinding film disk and the first roller and the second roller below, and compensates for the offset for the second time. This design avoids the offset of the front-end material film caused by compensating a large offset at one time during the deviation correction process.

[0018] 3. In the present invention, by setting the covering structure, the range of covering the optical signal emission window of the deviation correction sensor by the covering structure can be adjusted, which is applicable to the processing of various models of wound capacitor cores.

[0035] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0036] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0037] Embodiment, according to Figure 1 - Figure 8 ,as Figure 1As shown in the figure, a capacitor winding machine with a film deviation rectification function provided by an embodiment of the present invention includes an unwinding material disk mechanism 1, a tension mechanism 11, a pressure wheel mechanism 12, a winding mechanism 13, a core transfer mechanism 14, a flattening mechanism 15, and a conveyor belt 16, as Figure 2 shown in, the unwinding material disk mechanism 1 includes a support plate 2, on which an unwinding film disk 23 is installed. The upper and lower sides of the support plate 2 are respectively slidably connected with a carrier disk 21 and a chassis 22. Deviation rectification drivers 24 are installed between the support plate 2 and the carrier disk 21 and the chassis 22. A first roller 3 is installed on the support plate 2, and second rollers 31 are installed on both the carrier disk 21 and the chassis 22. Deviation rectification sensors 4 are arranged between the two second rollers 31 and the first roller 3. The two deviation rectification sensors 4 are respectively installed on the support plate 2 and the chassis 22, as Figure 5 shown in, the deviation rectification sensor 4 installed on the support plate 2 is also provided with a covering structure 6 for adjusting the monitoring range. The unwinding material disk mechanism 1 can compensate for the offset of film winding in two times. The deviation of the film is first detected by the deviation rectification sensor 4 installed on the support plate 2. Since the detection range of this deviation rectification sensor 4 is limited by the covering structure 6, and the covering range of the covering structure 6 is a controllable variable, that is, it can limit the deviation rectification sensor 4 to only detect the deviation beyond the covering range. After controlling the deviation rectification driver 24 between the support plate 2 and the carrier disk 21 to drive the unwinding film disk 23 to move, when the carrier disk 21 moves with the unwinding film disk 23, since the positions of the first roller 3 and the deviation rectification sensor 4 installed on the support plate 2 are fixed, the film released by the unwinding film disk 23 is displaced on the first roller 3 to perform the first offset compensation and correct the film deviation in a small range. The film continues to be transmitted, and the deviation of the film is detected a second time by the deviation rectification sensor 4 installed on the chassis 22. The deviation rectification driver 24 between the support plate 2 and the chassis 22 is controlled to operate, so that the support plate 2, the carrier disk 21, and the unwinding film disk 23 are relatively stationary. The film released by the unwinding film disk 23 is transmitted through the first roller 3 and has a relative displacement with the second roller 31 on the chassis 22 to perform the second offset compensation and correct the film deviation. The process of correcting the film with a large offset is divided into two steps for offset compensation, so as to perform deviation rectification in time when winding the capacitor core at high speed and prevent the adverse effect of excessive compensation displacement on the film that has been corrected at the front end from causing secondary deviation.

[0038] As Figure 3 shown in Figure 5 and 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;

[0039] 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;

[0040] 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.

[0041] Between the unwinding material reel mechanism 1, the tension mechanism 11, the pressure wheel mechanism 12 and the winding mechanism 13, there are several rollers 111 for restricting the transmission path of the film, which are used to restrict the transmission path a of the film material; As Figure 1 In the figure, there are four unwinding material reel mechanisms 1, including the material reel mechanism one 101, the material reel mechanism two 102, the inner packaging material reel mechanism 103 and the outer packaging material reel mechanism 104. The material reel mechanism one 101 and the material reel mechanism two 102 synchronously place the metallized film. The inner packaging material reel mechanism 103 places the inner packaging film, and the outer packaging material reel mechanism 104 places the outer packaging film; The winding mechanism 13 includes a turning shaft 131 and a working station 132. The turning shaft 131 is used to drive the working station 132 to rotate, and the position of the working station 132 is changed to wind the inner lining, the capacitor core and the outer layer of the capacitor core.

[0042] In this embodiment, the capacitor core is first wound with the inner packaging film released by the outer packaging material reel mechanism 104 on the working station 132 to form the inner lining of the capacitor core; Then, the material reel mechanism one 101 and the material reel mechanism two 102 simultaneously release the metallized film and pass along the material film path through the roller two 31 on the bearing seat 56, the deviation rectifying sensor 4 on the side mounting frame 32, the roller one 3, the deviation rectifying sensor 4 on the chassis 22, the roller two 31, the roller 111 and the tension mechanism 11, and are wound into the capacitor core in the working station 132; The outer packaging material reel mechanism 104 releases the outer packaging film and wraps it around the outer layer of the capacitor core in the working station 132 to form the outer layer; Subsequently, the core is sent by the core transfer mechanism 14 to the lower part of the flattening mechanism 15 for pre-flattening. Finally, the core is sent to the next process by the conveyor belt 16.

[0043] As Figure 8 Shown in the figure is the system feedback diagram of the deviation rectifying driver 24 and the deviation rectifying sensor 4. The set value of the film position and the feedback value transmitted from the deviation rectifying sensor 4 are processed by the PLC and then the control quantity is output to the deviation rectifying driver 24. The deviation rectifying driver 24 controls the front and back positions of the unwinding film reel 23 to control the position of the unwinding film. The disturbance quantity is the influencing factors such as the installation position of the unwinding film reel 23 not being parallel to the support plate 2 and the perpendicularity of the roller 111.

[0044] As Figure 7As shown in the figure, it is a schematic diagram of the deviation correction sensor 4 for detecting the position and offset of the film. The rapid and accurate detection of the offset during the film conveying process is the prerequisite for the normal operation of the deviation correction compensation offset; the optical signal is emitted from the upper window of the sensor and returns through the lower receiving window, and the size and position of the detected object are judged according to the width of the returned optical signal; when there is no obstacle in the U-shaped groove of the sensor, the optical signal emitted from 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 lower receiving window of the U-shaped groove is completely blocked and there is no optical signal, the light receiving intensity at this time is 0, and the corresponding output voltage is 0 V;

[0045] When the film is in different positions in the U-shaped groove of the sensor, the light transmission amount is also different, and the corresponding output voltage Ui is also different; set the inner edge of the film in the middle position of the optical signal of the sensor, and at this time the output voltage U0 = +5V; assume that the width of the light-emitting signal of the sensor is S, and the system deviation correction accuracy is ±δmm. When the sensor output voltage Ui > U0 + (10δ / S), it means that the film is offset to the outside, and at this time, the deviation correction driver 24 needs to drive the unwind film reel 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 at this time, the deviation correction driver 24 needs to drive the unwind film reel 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 deviation correction range, and there is no need to move the deviation correction driver 24;

[0046] (It should be noted that due to the setting of the covering structure 6 and the design of the deviation correction sensor 4 on the side mounting frame 32, the deviation correction sensor 4 installed on the unwind film reel 23 is suitable for monitoring the situation when the film material has a large offset. The deviation correction sensor 4 installed on the unwind film reel 23 is provided with a set of upper and lower windows on both sides of the film. Its working principle is basically the same as the above. The difference is that when the voltage output by one side of the sensor decreases, the deviation correction driver 24 is controlled to push the unwind film reel 23 to move to the opposite side to perform the first offset compensation. The purpose is to limit the detection range of the optical signal on the deviation correction sensor 4 by covering a certain area of the optical signal emission window of the deviation correction sensor 4 on the side mounting frame 32 with the sliding cover 61. When the offset range of the film exceeds, the deviation correction driver 24 is controlled to drive the carrier plate 21 to slide on the support plate 2, and the unwind film reel 23 and the roller two 31 located above move relative to the roller one 3 to compensate for the offset of the material film beyond the covering range of the covering structure 6. When the sensor output voltage is stable, it means that the film offset does not require a large displacement compensation, and the offset compensation is performed again when detecting the film offset for the second time).

[0047] In this embodiment, during the process of correcting the deviation of the wound capacitor core, when the unwinding film disc 23 releases the material film, when passing through the second roller 31 above and the first roller 3, the deviation sensor 4 installed on the side mounting frame 32 detects the deviation of the material film for the first time. The light signal emission windows on the inner and outer sides of the material film are covered by two sliding covers 61 to limit the detection range of the deviation sensor 4. The light signal on the side beyond the coverage range of the sliding cover 61 is further blocked, reducing the output voltage of the deviation sensor 4. The deviation driver 24 between the support plate 2 and the carrier plate 21 is controlled by the PLC. The output end of the deviation driver 24 drives the unwinding film disc 23 to move to the opposite side through the push bearing seat 56, compensating for the deviation of the material film for the first time. The material film continues to be transported. When passing between the first roller 3 and the second roller 31 installed on the chassis 22, the deviation sensor 4 installed on the chassis 22 detects the deviation of the material film for the second time. The deviation driver 24 between the support plate 2 and the chassis 22 is controlled by 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 carrier plate 21 are relatively stationary, causing relative displacement between the unwinding film disc 23, the first roller 3 and the second roller 31 installed on the chassis 22, compensating for the deviation of the material film, and correcting the deviation of the material film in a timely manner. The deviation correction process operates stably. When winding the capacitor core at high speed, the end face flatness of the capacitor core is improved. When the material film has a large deviation, the first and second deviation compensations are performed, effectively avoiding excessive deviation correction actions that may cause the material film on the front-end transmission path to be disturbed and have a secondary deviation, ensuring the stability of the effect of improving the end face flatness of the capacitor core.

[0048] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention in any other form. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
