Description

Technical Field

[0001] This application relates to the field of capacitor manufacturing technology, specifically to a feeding device and capacitor manufacturing equipment. Background Technology

[0002] The capacitor core is the core component of a capacitor, used to store and release electrical charge, and is typically made of a metallized thin film wound up. For example... Figure 1 and Figure 2 As shown, after the capacitor core 100 is wound, it forms a hollow cylindrical main body 101 and a first lead 102 and a second lead 103 connected to the main body.

[0003] like Figure 3 As shown, after the capacitor core 100 is wound, it needs to be unloaded from the winding device and flattened. It is also necessary to ensure that the first lead 102 and the second lead 103 are aligned after flattening. That is, the first lead 102 and the second lead 103 are aligned... Figure 3 From a perspective, it is basically axially symmetrical. Existing feeding devices use a flat plate clamping method for feeding and flattening. During flattening, the radial direction of the capacitor core 100 is uncontrolled, which leads to misalignment of the first lead 102 and the second lead 103 after the capacitor core 100 is flattened. That is, in such a case... Figure 4 From the perspective shown, the first lead 102 and the second lead 103 are offset to the left and right and are not aligned. Utility Model Content

[0004] One objective of this application is to provide a new technical solution for a feeding device and a cell winding device.

[0005] To achieve the above objectives, according to a first aspect of this application, a feeding device is provided, comprising:

[0006] A gripper assembly, the gripper assembly including a pressure plate, a positioning block and an elastic element, the pressure plate having a pressing surface, the positioning block having an arcuate surface, and the elastic element providing a spring force that causes the arcuate surface to move away from the pressing surface in a first direction;

[0007] A gripper drive assembly, wherein the gripper drive assembly is used to drive at least two gripper assemblies to move closer or further apart from each other along a first direction, and the arcuate surfaces of at least two positioning blocks are arranged opposite each other;

[0008] In the initial state, at least a portion of the arcuate surfaces of the two positioning blocks is located between the pressing surfaces of the two pressure plates.

[0009] Alternatively, the feeding device may further include a guide rod, which is slidably engaged with the gripper assembly. One end of the guide rod is connected to the positioning block, and the other end of the guide rod is connected to the limiting member. The elastic member is sleeved on the guide rod.

[0010] Alternatively, the pressure plate may also have an opening in which the positioning block is movable.

[0011] Alternatively, the gripper drive assembly includes;

[0012] Clamping drive components;

[0013] Gear, wherein the clamping drive is used to drive the gear to rotate;

[0014] A first rack, which meshes with the gear, and the first rack is connected to a first connecting plate;

[0015] The second rack meshes with the gear and is connected to the second connecting plate.

[0016] The first connecting plate and the second connecting plate are respectively connected to the gripper assembly, and the rotation of the gear causes the first connecting plate and the second connecting plate to move closer to or further away from each other along a first direction.

[0017] Alternatively, the feeding device may further include a flipping drive assembly for driving at least two of the gripper assemblies to flip about an axis in a second direction, the first direction intersecting the second direction.

[0018] Alternatively, the flip drive assembly includes: a flip drive member; a rotating shaft, the flip drive member being used to drive the rotating shaft to rotate about an axis in the second direction; and the gripper drive assembly being mounted on the rotating shaft.

[0019] Alternatively, the unloading device may further include a translation drive assembly for driving at least two of the gripper assemblies to translate along a third direction, the first direction intersecting the third direction.

[0020] Optionally, the translation drive assembly includes: a translation drive member; a movable seat, to which the gripper drive assembly is connected; and a fixed seat, to which the translation drive member is mounted; the movable seat and the fixed seat are slidably engaged, and the translation drive member is used to drive the movable seat to slide relative to the fixed seat along the third direction.

[0021] Optionally, the unloading device further includes a flipping drive assembly and a translation drive assembly; the flipping drive assembly is mounted on a movable base, the translation drive assembly is mounted on a fixed base, the fixed base and the movable base are slidably engaged, the translation drive assembly drives the movable base to slide relative to the fixed base along a third direction, and the flipping drive assembly is used to drive the gripper assembly drive assembly to rotate around the axis of the second direction, so as to drive at least two gripper assemblies to flip around the axis of the second direction, wherein the first direction, the second direction and the third direction intersect each other.

[0022] According to another aspect of this application, a capacitor manufacturing apparatus is also provided, including a feeding device as described in any of the preceding claims.

[0023] In this embodiment of the unloading device, after reaching the unloading station, the gripper drive assembly drives the two gripper assemblies to move closer to each other along a first direction. Since at least a portion of the two arc-shaped surfaces are initially located between the two pressing surfaces, the arc-shaped surfaces of the positioning blocks on the two gripper assemblies can support the main body of the capacitor core. Next, the gripper drive assembly continues to drive the two gripper assemblies closer to each other along the first direction, compressing the elastic element. The resulting elastic force causes the arc-shaped surfaces of the two positioning blocks to clamp the main body of the capacitor core, thus preventing the capacitor core from rolling during unloading. As the two gripper assemblies continue to move closer to each other along the first direction, the arc-shaped surfaces approach the pressing surfaces, and the pressing surfaces begin to abut against the main body of the capacitor core. The gripper drive assembly continues to operate, and the pressure plates of the two gripper assemblies continue to move closer, flattening the capacitor core with the two pressing surfaces. During this process, since the arc-shaped surfaces continuously clamp the main body of the capacitor core, the radial position of the capacitor core is controlled, allowing for the pressing out of the capacitor core as described above. Figure 3 The capacitor core shown is of good quality, thus avoiding defects such as... Figure 4 The misalignment of the first and second leads of the capacitor core shown in the diagram improves the yield rate of the capacitor.

[0043] In the following description, “connection” includes both direct connection between the two and indirect connection between the two through, for example, adapters, middleware, etc.

[0044] In the following description, the capacitor core 100 is used only to illustrate the working principle of the feeding device and capacitor production equipment, and should not be considered as part of the feeding device and capacitor production equipment.

[0045] In the following description, each drive component can be driven by a variety of power sources such as cylinders and motors.

[0046] like Figures 5 to 8 As shown, the unloading device 200 in the first embodiment of this application includes a gripper assembly and a gripper drive assembly 211. The gripper assembly includes a pressure plate 205, a positioning block 208, and an elastic element 210. The pressure plate 205 has a pressing surface 206. The positioning block 208 has an arcuate surface 209. The elastic element 210 provides a spring force that causes the arcuate surface 209 to move away from the pressing surface 206 along a first direction. The gripper drive assembly 211 is used to drive at least two of the gripper assemblies to move closer to or further away from each other along the first direction, with the arcuate surfaces 209 of at least two grippers being disposed opposite each other. In the initial state, at least a portion of the arcuate surfaces 209 of the two positioning blocks 208 are located between the pressing surfaces 206 of the two pressure plates 205.

[0047] Specifically, such as Figure 5 and Figure 6 As shown, for clarity, the two opposing gripper assemblies are labeled as the first gripper assembly 203 and the second gripper assembly 204, respectively. One or more first gripper assemblies 203 are mounted on the first mounting plate 201, and one or more second gripper assemblies 204 are mounted on the second mounting plate.

[0048] like Figure 7 and Figure 8As shown, the first gripper assembly 203 includes a pressure plate 205, the pressing surface 206 of which applies pressure to the main body portion 101 of the capacitor core 100 to flatten it. The arcuate surface 209 of the positioning block 208 can match the outer contour of the main body portion 101 of the capacitor core 100, and is used to clamp the main body portion 101 of the capacitor core 100 during unloading, thereby positioning the capacitor core 100 and preventing the capacitor core 100 from rolling during unloading. The positioning block 208 can move within the opening 207 of the pressure plate 205 or on the side of the pressure plate 205, for example, in... Figure 6 In the view shown, if the positioning block 208 of the first gripper assembly 203 moves upward along the first direction, the arcuate surface 209 will move closer to the pressing surface 206 along the first direction. Conversely, if the positioning block 208 of the first gripper assembly 203 moves downward along the first direction, the arcuate surface 209 will move away from the pressing surface 206 along the first direction. The elastic element 210 can be a coil spring, a spring sheet, etc. The elastic element 210 is disposed on the first gripper assembly 203. In the initial state where the arcuate surface 209 of the positioning block 208 does not clamp the main body 101 of the capacitor core 100, the elastic element 210 can be in a natural state or deform to support the weight of the positioning block 208 mounted on the second gripper assembly 204. When the arcuate surface 209 of the positioning block 208 is clamping the main body 101 of the capacitor core 100, the elastic element 210 can deform. This deformation causes the elastic element 210 to provide elastic force, which causes the arcuate surface 209 to tend to move away from the pressing surface 206 along the first direction. The structure of the second gripper assembly 204 is the same as that of the first gripper assembly 203, except that the installation direction is reversed, and will not be described in detail here. In the initial state, that is, when the arcuate surface 209 of the positioning block 208 is not clamping the main body 101 of the capacitor core 100, due to the action of the elastic element 210, at least a portion of the arcuate surface 209 of the positioning block 208 of the first gripper assembly 203 and at least a portion of the arcuate surface 209 of the positioning block 208 of the second gripper assembly 204 are located between the pressing surface 206 of the first gripper assembly 203 and the pressing surface 206 of the second gripper assembly 204. In other words, there are a portion of two opposing arcuate surfaces 209 in the space between the pressing surface 206 of the first gripper assembly 203 and the pressing surface 206 of the second gripper assembly 204, or both opposing arcuate surfaces 209 are located entirely in the space between the pressing surface 206 of the first gripper assembly 203 and the pressing surface 206 of the second gripper assembly 204.

[0049] In the embodiments of this application, the gripper drive assembly 211 can employ both... Figure 9The structure shown can also employ other suitable structures such as gripper cylinders. Taking the gripper cylinder as the gripper drive assembly 211 as an example, the two ends of the gripper cylinder are respectively connected to the first mounting plate 201 and the second mounting plate 202. When the gripper cylinder is activated, it can drive the first gripper assembly 203 on the first mounting plate 201 and the second gripper assembly 204 on the second mounting plate 202 to move closer or further apart. The first mounting plate 201 and the second mounting plate 202 can also be considered as part of the gripper drive assembly 211. Furthermore, at least one first gripper assembly 203 on the first mounting plate 201 is disposed opposite to one second gripper assembly 204 on the second mounting plate 202. That is, the arc-shaped surface 209 of the positioning block 208 mounted on at least one first gripper assembly 203 is disposed opposite to the arc-shaped surface 209 of the positioning block 208 mounted on one second gripper assembly 204. Correspondingly, the pressing surface 206 on the first gripper assembly 203 is also disposed opposite to the pressing surface 206 on the second gripper assembly 204.

[0050] During operation, the gripper drive assembly 211 drives the first gripper assembly 203 and the second gripper assembly 204 to move away from each other along a first direction, opening the pair of gripper assemblies. Initially, the arcuate surface 209 does not hold the capacitor core 100. Then, the unloading device 200 reaches the unloading station, and the gripper drive assembly 211 drives the first gripper assembly 203 and the second gripper assembly 204 to move closer to each other along the first direction. The arcuate surfaces 209 of the positioning blocks 208 on the first gripper assembly 203 and the second gripper assembly 204 support the main body 101 of the capacitor core 100. Next, the gripper drive assembly 211 continues to drive the first gripper assembly 203 and the second gripper assembly 204 to move closer to each other along the first direction. The elastic element 210 is compressed, and the resulting elastic force causes the arcuate surfaces 209 of the two positioning blocks 208 to hold the main body 101 of the capacitor core 100, so the capacitor core 100 will not roll during the unloading process. As the first gripper assembly 203 and the second gripper assembly 204 continue to approach each other along the first direction, the arc-shaped surface 209 approaches the pressing surface 206 along the first direction, and the pressing surface 206 begins to abut against the main body portion 101 of the capacitor core 100. The gripper drive assembly 211 continues to operate, and the pressure plate 205 of the first gripper assembly 203 and the pressure plate of the second gripper assembly 204 continue to approach each other, and the two pressing surfaces 206 flatten the capacitor core 100. During this process, because the arc-shaped surface 209 continuously clamps the main body portion 101 of the capacitor core 100, the radial position of the capacitor core 100 is controlled, enabling it to be pressed out as shown in the image. Figure 3 The capacitor core 100 shown is of good quality, thus avoiding defects such as... Figure 4 The misalignment of the first lead 102 and the second lead 103 of the capacitor core 100 shown in the figure improves the yield rate of the capacitor.

[0051] like Figure 7 and Figure 8 As shown, the feeding device 200 also includes a guide rod 212, which is slidably engaged with the gripper assembly. One end of the guide rod 212 is connected to the positioning block 208, and the other end of the guide rod 212 is connected to the limiting member 213. The elastic member 210 is sleeved on the guide rod 212.

[0052] Taking the first gripper assembly 203 as an example, the guide rod 212 passes through the through hole on the first gripper assembly 203 and slides in engagement with it. One end of the guide rod 212 is connected to the positioning block 208, and the other end is connected to the limiting member 213. Therefore, the movement stroke of the positioning block 208 is limited, resulting in a simple structure. The guide rod 212 also ensures that the positioning block 208 will not fall off the opening 207. In other embodiments of this application, the positioning block 208 can also slide in engagement with the first gripper assembly 203 via a linear guide, but this would make the structure more complex. The elastic member 210 can be in the form of a helical spring. During assembly, the guide rod 212 is first connected to the positioning block 208, then the elastic member 210 is fitted onto the guide rod 212, and then the guide rod 212 passes through the opening 207 and the through hole on the first gripper assembly 203 before connecting to the limiting member 213, simplifying assembly. During assembly, the elastic member 210 can be given a certain preload or left at its natural length.

[0053] like Figures 5 to 8 As shown, the pressure plate 205 also has an opening 207, within which the positioning block 208 can move.

[0054] Specifically, the opening 207 can be a through hole or a notch in the pressure plate 205. The positioning block 208 moves within the opening 207, allowing more pairs of pressure plates 205 to be arranged along the length of the capacitor core 100, thus achieving a better flattening effect for the capacitor core 100.

[0055] like Figure 9 As shown, the first embodiment of this application discloses a specific structure of a gripper drive assembly 211. The gripper drive assembly 211 includes: a gripping drive member 214; a gear 215, the gripping drive member 214 being used to drive the gear 215 to rotate; a first rack 216, the first rack 216 meshing with the gear 215, the first rack 216 being connected to a first connecting plate 217; a second rack 218, the second rack 218 meshing with the gear 215, the second rack 218 being connected to a second connecting plate 219; the first connecting plate 217 and the second connecting plate 219 are respectively connected to the gripper assembly, and the rotation of the gear 215 causes the first connecting plate 217 and the second connecting plate 219 to move closer to or further away from each other along a first direction.

[0056] Specifically, the clamping drive 214 can drive the gear 215, for example, by a motor drive. The clamping drive 214 is mounted on the fixed block 220, and its shaft is connected to the gear 215. The first rack 216 and the second rack 218 both mesh with the gear 215 after passing through the through holes in the fixed block 220. Therefore, after the clamping drive 214 drives the gear 215 to rotate, the first rack 216 and the second rack 218 will perform linear motion. The first rack 216 is connected to the first connecting plate 217, and the second rack 218 is connected to the second connecting plate 219. Figure 9 In the view shown, when gear 215 rotates clockwise, the first connecting plate 217 moves in the direction indicated by the first direction arrow, and the second connecting plate 219 moves in the opposite direction of the first direction arrow, thus moving the first connecting plate 217 and the second connecting plate 219 away from each other; when gear 215 rotates counterclockwise, the first connecting plate 217 moves in the opposite direction of the first direction arrow, and the second connecting plate moves in the direction indicated by the first direction arrow, thus moving the first connecting plate 217 and the second connecting plate 219 closer to each other. The first connecting plate 217 is connected to the first mounting plate 201, and the second connecting plate 219 is connected to the second mounting plate 202. At this time, the first mounting plate 201 can also be regarded as part of the first connecting plate 217, and the second mounting plate 202 can also be regarded as part of the second connecting plate 219. Therefore, the first connecting plate 217 is connected to the first gripper assembly 203, and the second connecting plate 219 is connected to the second gripper assembly 204. The first connecting plate 217 and the second connecting plate 219 move closer or further apart, which in turn causes the first gripper assembly 203 and the second gripper assembly 204 to move closer or further apart, thereby realizing the feeding and flattening of the capacitor core 100. Using such... Figure 9 The advantage of the structure of the gripper drive assembly 211 shown is that by adjusting the meshing position of the first rack 216, the second rack 218 and the gear 215, or by controlling the motor rotation angle when a motor is used, the stroke of the first gripper assembly 203 and the second gripper assembly 204 can be adjusted, which provides better versatility for capacitor cores 100 of different diameters.

[0057] like Figure 9 As shown, the unloading device 200 in the second embodiment of this application further includes a flipping drive component 221, which is used to drive at least two of the gripper components to flip around an axis in a second direction, wherein the first direction intersects the second direction.

[0058] Specifically, the flip drive assembly 221 can use a motor, cylinder multi-link mechanism, etc. to drive the gripper drive assembly 211 to flip around the axis of the second direction. The flipping of the gripper drive assembly 211 will drive the first gripper assembly 203 and the second gripper assembly 204 to flip around the axis of the second direction, thereby facilitating the transfer of the capacitor core 100.

[0059] like Figure 9 As shown in the second embodiment of this application, a structure of the flip drive assembly 221 is specifically illustrated. The flip drive assembly 221 includes: a flip drive member 222; a rotating shaft 223, wherein the flip drive member 222 is used to drive the rotating shaft 223 to rotate about the axis of the second direction; and the gripper drive assembly 211 is mounted on the rotating shaft 223.

[0060] Specifically, the flipping drive component 222 can be a motor, a cylinder, a multi-link mechanism, etc., connected to the rotating shaft 223, thereby driving the rotating shaft 223 to rotate around the axis in the second direction. The fixed block 220 is fixedly connected to the rotating shaft 223. The advantage of using the rotating shaft 223 is that it provides more installation space for the fixed block 220. Moving the installation position of the fixed block 220 will correspondingly change the installation position of the gripper drive assembly 211, which can accommodate different numbers of gripper assemblies installed on the first mounting plate 201 and the second mounting plate 202.

[0061] like Figure 10 As shown, the unloading device 200 in the third embodiment of this application further includes a translation drive component 225, which is used to drive at least two of the gripper components to translate along a third direction, wherein the first direction intersects with the third direction.

[0062] Specifically, although in Figure 10 In this embodiment, the translation drive component 225 achieves the translation of the gripper assembly along a third direction by driving the translation of the flip drive component 221. However, this application does not exclude the possibility that the translation drive component 225 can directly drive the gripper drive component 211 to translate, thereby achieving the translation of the gripper assembly along a third direction. In this case, the flip drive component 221 may not be necessary. By using the translation drive component 225, the degrees of freedom of the first gripper assembly 203 and the second gripper assembly 204 can be increased, which facilitates the space avoidance of the capacitor core 100 winding device by the transfer and unloading device 200.

[0063] like Figure 10 As shown, in the third embodiment of this application, a specific structure of the translation drive assembly 225 is disclosed. The translation drive assembly 225 includes: a translation drive member 226; a movable seat 224, to which the gripper drive assembly 211 is connected; and a fixed seat 227, on which the translation drive member 226 is mounted; the movable seat 224 and the fixed seat 227 are slidably engaged, and the translation drive member 226 is used to drive the movable seat 224 to slide relative to the fixed seat 227 along the third direction.

[0064] Specifically, in such Figure 10In the structure shown, the translation drive 226 is a motor that drives the movable seat 224 to slide relative to the fixed seat 227 via belt drive. A slide rail 228 is mounted on the fixed seat 227 to improve the sliding stability of the movable seat 224. In other embodiments of this application, the translation drive 226 can also use a screw drive or similar method to drive the movable seat 224 to slide relative to the fixed seat 227. The gripper drive assembly 211 is directly or indirectly connected to the movable seat 224. Therefore, when the movable seat 224 slides along a third direction, it can drive the gripper drive assembly 211 to translate along a third direction, further driving the first gripper assembly 203 and the second gripper assembly 204 to translate along a third direction. The structure is simple.

[0065] like Figure 10 As shown in the third embodiment of this application, the first gripper assembly 203 and the second gripper assembly 204 of the unloading device 200 simultaneously possess three degrees of freedom: movement along a first direction, rotation around an axis in a second direction, and translation along a third direction. The unloading device 200 also includes a rotation drive assembly 221 and a translation drive assembly 225; the rotation drive assembly 221 is mounted on a movable base 224, and the translation drive assembly 225 is mounted on a fixed base 227. The fixed base 227 and the movable base 224 are slidably engaged. The translation drive assembly 225 drives the movable base 224 to slide relative to the fixed base 227 along a third direction. The rotation drive assembly 221 is used to drive the gripper drive assembly 211 to rotate around an axis in the second direction, thereby causing at least two of the gripper assemblies to rotate around an axis in the second direction. The first direction, the second direction, and the third direction intersect each other.

[0066] Specifically, the movable seat 224 slides in conjunction with the slide rail 228 on the fixed seat 227. The flipping drive 222 and the rotating shaft 223 are both mounted on the movable seat 224, and the gripper drive assembly 211 is mounted on the rotating shaft 223. Therefore, when the translation drive 226 drives the movable seat 224 to translate along a third direction, both the flipping drive assembly 221 and the gripper drive assembly 211 will translate along the third direction. When the flipping drive 222 drives the rotating shaft 223 to rotate, the gripper drive assembly 211 will also flip around the axis of the second direction. In this way, the first gripper assembly 203 and the second gripper assembly 204 realize movement along the first direction, flipping around the axis of the second direction, and translation along the third direction, which facilitates the feeding, flattening, and transfer of the capacitor core 100.

[0067] This application also discloses a capacitor manufacturing apparatus, including the feeding device 200 as described above. The capacitor manufacturing apparatus, by employing the feeding device 200 as described above, improves the yield rate of capacitors.

As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
