Description

Technical Field

[0001] This invention relates to the field of capacitor technology, and in particular to a capacitor production equipment. Background Technology

[0002] A capacitor is a device that stores electrical charge. It is one of the most widely used electronic components in electronic devices, and is widely used in circuits for DC blocking and AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control.

[0003] The manufacturing process of existing film capacitors mainly includes the following steps: (1) Making the core: The core can be made by overlapping and winding metal foil (the metal foil serves as the electrode) and plastic film together, or by depositing a very thin layer of metal (the deposited metal layer serves as the electrode) onto the plastic film to obtain a metallized film, and then winding the metallized film to make the core; The core made by winding is usually cylindrical (usually, the cylindrical core is flattened by hot pressing to make a flat cylindrical core); (2) Energizing the core: Energizing is to apply voltage to the two conductive ends of the core to eliminate the internal conductive defects of the core and make the internal conductive defects of the core self-heal; (3) Welding the leads: Welding is to weld conductive leads to the two conductive ends of the core; (4) Encapsulation: Encapsulation is to impregnate the core with welded leads with epoxy resin, or to put the core with welded leads into a plastic shell and fill the plastic shell with epoxy resin to fix the core. After the core goes through the processes of energizing, welding leads, and encapsulation, it becomes a finished capacitor.

[0004] To improve processing efficiency, long conductive leads need to be fed into the system, cut to appropriate lengths, and then U-bent. The bent leads are then transferred to the bonding area, while paper tape and adhesive tape are automatically conveyed to the bonding area. The U-shaped leads are then bonded to the paper tape using the adhesive tape, forming a lead tape. The lead tape then transfers the leads on it to the soldering area. After the core has undergone energizing treatment, it is transferred to the soldering area where the leads are soldered to the two conductive ends of the core. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a capacitor production equipment that can automate the processing of lead strips, energize the core, and then weld the two conductive ends of the core to the leads on the lead strip, thereby improving processing efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a capacitor production equipment, comprising a frame, wherein a lead wire processing device, an energizing device, a welding device, and a conveyor track are arranged on the frame; the lead wire processing device includes a paper tape feeding mechanism, an adhesive tape feeding mechanism, a lead wire feeding mechanism, and a pressing mechanism; the energizing device includes an energizing mechanism and a feeding mechanism; the welding device includes a welding mechanism and a core-attaching mechanism; and the frame is provided with a welding area for welding the leads to the core.

[0007] The lead wire feeding mechanism includes a lead wire conduction assembly, a lead wire traction assembly, a lead wire cutting assembly, and a lead wire forming and pushing assembly arranged sequentially along the X-axis.

[0008] The pressing mechanism includes a support platform, a pressing block, and a first driving unit. The support platform is located at the end of the conveying track, and the area above the support platform is the adhesive area. The pressing block is slidably mounted on the frame in the vertical direction. The first driving unit can drive the pressing block to move up and down, thereby pressing against the support platform. The frame is provided with a material distribution block near the support platform.

[0009] The paper tape feeding mechanism can convey the paper tape from below the dispensing block to the bonding area;

[0010] The tape feeding mechanism can convey the tape from above the dispensing block to the bonding area;

[0011] The lead conduction assembly can guide and transmit the lead to the lead traction assembly;

[0012] The lead wire pulling assembly can pull and transmit the lead wire to the lead wire cutting assembly;

[0013] The lead cutting assembly can cut the lead and convey it to the lead forming and pushing assembly;

[0014] The lead wire forming and pushing assembly includes a base, a forming seat, a stop block, and a second drive unit. The base is fixedly mounted on the frame, and the forming seat is slidably mounted on the base along the Y-axis. The second drive unit can drive the forming seat to slide along the Y-axis. The forming seat has a cavity, and the stop block is placed in the cavity. The forming seat has abutment blocks on both sides of the cavity. When the forming seat moves backward, the two abutment blocks can press against both ends of the lead wire, and the middle of the lead wire is stopped by the stop block, thereby forming a U-shaped lead wire. When the forming seat moves forward, it can move the U-shaped lead wire to the bonding area.

[0015] The conveyor track is used for lead wire conveying. The conveyor track is set along the X-axis. When the lead wire is conveyed along the conveyor track, the lead wire can move the U-shaped lead wires on it one by one to the welding area.

[0016] The empowerment mechanism includes a rotating disk rotatably mounted on a frame. A plurality of clamping assemblies are spaced circumferentially along the upper surface of the rotating disk. Each clamping assembly includes a first conductive clamp and a second conductive clamp. The first and second conductive clamps are movably mounted on the rotating disk, forming a clamping area. The first and second conductive clamps can clamp or open with each other. A charging area and a discharging area are sequentially arranged on the rotation trajectory of the rotating disk along the frame. The empowerment mechanism also includes a charging component and a discharging component. The charging component is located in the charging area of ​​the rotating disk, and the discharging component is located in the discharging area of ​​the rotating disk. When the core rotates with the rotating disk to the charging area, the charging component is electrically connected to the first and second conductive clamps to charge the core. When the core rotates with the rotating disk to the discharging area, the discharging component is electrically connected to the first and second conductive clamps to discharge the core.

[0017] The feeding mechanism can transport the unenergized cores one by one to the clamping area;

[0018] The welding mechanism includes a first heating block and a second heating block arranged opposite to each other. The first heating block and the second heating block are mounted on the frame and can move along the X-axis. The first heating block and the second heating block can move towards each other or away from each other. The first heating block and the second heating block can also move simultaneously along the vertical direction and can move into or out of the welding area at the same time.

[0019] The aforementioned core-loading mechanism can transfer the energized core from the rotating disk to the welding area.

[0020] By adopting the above scheme, automatic lead wire feeding and cutting of the lead wire to a suitable length can be achieved. The forming seat moves backward under the drive of the second drive unit. Two abutment blocks on the forming seat press against both ends of the lead wire, while the middle of the lead wire is stopped by a stop block, thus forming a U-shaped lead wire. Then, the forming seat moves forward under the drive of the second drive unit, carrying the U-shaped lead wire and transferring it to the bonding area. When the forming seat moves backward again, it can form the next U-shaped lead wire, and so on. The paper tape is conveyed from below the distribution block to the bonding area, and the adhesive tape is conveyed from above the distribution block to the bonding area. The forming seat pushes the U-shaped lead wire between the paper tape and the adhesive tape. At this time, the first drive unit drives the pressure block to move downwards. By pressing against the adhesive tape, the U-shaped leads can be adhered to the paper tape through the adhesive tape to form a lead tape. With automated processing, the U-shaped leads are spaced apart on the lead tape, and the conveyor track drives the lead tape to move. The rotating disk can be driven to rotate by an external drive mechanism. When the clamping assembly that does not hold the core rotates with the rotating disk to the side of the feeding mechanism, the first conductive clamp and the second conductive clamp open each other. The feeding mechanism conveys the core to the clamping area, and then the first conductive clamp and the second conductive clamp clamp the core. When the core rotates with the rotating disk to the charging area, the charging component is electrically connected to the first conductive clamp and the second conductive clamp respectively to achieve charging. The charging operation of the core: When the core rotates with the rotating disk to the discharge area, the discharge component is electrically connected to the first and second conductive clamps to discharge the core. When the core moves away from the discharge area with the rotating disk, the energizing process of the core is completed. The energized core then rotates with the rotating disk to the upper core mechanism, which can transfer the core to the welding area for the energizing process of the next core. Several clamping components are provided, allowing for continuous operation and improving energizing efficiency. The first and second electrothermal pressing blocks have similar structures and heat up after being energized. The U-shaped leads on the lead belt are transferred one by one under the conveyor rail. The core is moved to the welding area by the core-upper mechanism. The core is then thermo-pressed to the corresponding pins on the U-shaped lead wire. After thermo-pressing, the core can follow the lead wire into the subsequent processing steps. The next U-shaped lead wire can be thermo-pressed to the next core, allowing for continuous and uninterrupted operation, which improves welding efficiency. The first and second heating blocks can not only move towards or away from each other, but also move vertically into or out of the welding area. When welding is required, the first and second heating blocks can move into the welding area simultaneously and move towards each other to thermo-press both sides of the core, so that the leads are welded to the two conductive ends of the core.After welding is completed, the first and second heating blocks move in opposite directions and simultaneously leave the welding area to avoid interfering with the transmission of the lead strip. When welding the next core, the core loading mechanism sends the next core to the welding area, and the first and second heating blocks then move into the welding area. This system automates the processing of the lead strip and provides energy to the core. Then, the two conductive ends of the core are welded to the leads on the lead strip, improving processing efficiency.

[0021] A further feature of the present invention is that: the bottom of the cavity has grooves on the two opposite inner walls respectively; the ends of the two abutting blocks are respectively provided with guide surfaces, which are inclined toward one side of the groove; the stop block is movably mounted on the frame in the vertical direction; the frame is provided with a third drive unit that drives the stop block to move up and down; the downward movement of the stop block can press the U-shaped lead wire into the groove.

[0022] By adopting the above scheme and setting the guide surface, during the bending process of the lead wire, the guide surface can drive the lead wire to move down, the third drive unit drives the stop block to move down, the stop block can press the U-shaped lead wire into the groove, and then the stop block moves up to reset. This can ensure that the formed U-shaped lead wire will be transferred to the bonding area by the forming seat, and can work continuously. The structure is simple and the design is reasonable.

[0023] A further feature of the present invention is that the lead wire traction assembly includes a traction seat, a fourth drive unit, a first clamping plate, a second clamping plate, and a fifth drive unit. The traction seat is slidably mounted on the frame along the X-axis direction. The fourth drive unit drives the traction seat to reciprocate along the X-axis direction. The first clamping plate is slidably mounted on the traction seat along the Y-axis direction. The second clamping plate is fixedly or integrally mounted on the traction seat. The traction seat is provided with a first elastic element that drives the first clamping plate to move closer to the second clamping plate. The fifth drive unit can drive the first clamping plate to move away from the second clamping plate.

[0024] By adopting the above scheme, the fourth drive unit drives the traction seat to slide back and forth along the X-axis. When the traction seat moves away from the lead wire cutting component, the fifth drive unit drives the first clamping plate to move away from the second clamping plate, which will loosen the clamping of the lead wire. When the traction seat moves into position, the fifth drive unit removes the force on the first clamping plate. The first elastic element is the first spring. One end of the first spring abuts against the traction seat, and the other end abuts against the first clamping plate. The first spring drives the first clamping plate to move closer to the second clamping plate, which will clamp the lead wire. Then the traction seat moves closer to the lead wire cutting component, which can pull and transmit the lead wire. The structure is simple and the design is reasonable.

[0025] A further feature of the present invention is that the lead wire cutting mechanism includes a cutter holder, a first cutter, and a sixth drive unit. The cutter holder is fixedly mounted on the frame and has a lead wire hole for the lead wire to pass through. The first cutter is slidably mounted on the cutter holder along the Y-axis direction. The sixth drive unit can drive the first cutter to slide along the Y-axis direction, thereby causing the first cutter to cut the lead wire.

[0026] By adopting the above scheme, the sixth drive unit can drive the first cutter to cut the lead wire to a suitable length. The cut lead wire will not fall off due to the stop action of the lead wire hole, so as to facilitate the subsequent lead wire bending operation. The structure is simple and the design is reasonable.

[0027] A further feature of the present invention is that: the first conductive clamp is rotatably mounted on the rotating disk via a first rotating shaft, and the second conductive clamp is rotatably mounted on the rotating disk via a second rotating shaft. The first conductive clamp and the second conductive clamp are driven by a gear structure. The rotating disk is provided with a second elastic element that drives the first conductive clamp and the second conductive clamp to perform a clamping operation at all times. The frame is provided with a seventh drive unit near the feeding mechanism and the core-upper mechanism, respectively. The seventh drive unit drives the first rotating shaft or the second rotating shaft to rotate, thereby realizing the opening operation of the first conductive clamp and the second conductive clamp.

[0028] By adopting the above scheme, a first transmission gear is provided on the first conductive clamp, and a second transmission gear is provided on the second conductive clamp. The first transmission gear and the second transmission gear mesh with each other. Therefore, when the clamp assembly is loading or unloading the core, the seventh drive unit only needs to drive the first conductive clamp or the second conductive clamp to rotate, which can realize the opening operation of the first conductive clamp and the second conductive clamp. The second elastic element is a second spring. One end of the second spring abuts against the first conductive clamp, and the other end of the second spring abuts against the second conductive clamp. The second spring drives the first conductive clamp and the second conductive clamp to always perform clamping operation. The structure is simple and the design is reasonable.

[0029] A further feature of the present invention is that it includes several conductive components, each corresponding to a clamping component. Each conductive component includes a first conductive post and a second conductive post disposed on a rotating disk, penetrating the rotating disk. The first conductive post is electrically connected to a first conductive clamp, and the second conductive post is electrically connected to a second conductive clamp. The charging component includes a charging base located below the rotating disk, with a charging circuit board disposed on the charging base. An eighth driving unit is disposed on the frame to drive the charging base to move up and down. When the charging base moves upward, the charging circuit board on it contacts the lower ends of the corresponding first and second conductive posts to achieve electrical connection. The discharging component includes a discharging base located below the rotating disk, with a discharging circuit board disposed on the discharging base. A ninth driving unit is disposed on the frame to drive the discharging base to move up and down. When the discharging base moves upward, the discharging circuit board on it contacts the lower ends of the corresponding first and second conductive posts to achieve electrical connection.

[0030] By adopting the above scheme, the first conductive clamp and the second conductive clamp can be integral conductive components, or they can be insulating components. The first conductive clamp has a first conductive gripping head at one end, and the second conductive clamp has a second conductive gripping head at one end. The first and second conductive gripping heads are used to grip the core. The first conductive post is electrically connected to the first conductive gripping head via a wire, and the second conductive post is electrically connected to the second conductive gripping head via a wire. The charging circuit board has contacts adapted to the first and second conductive posts. When the eighth drive unit moves the charging base upwards, the charging circuit board contacts the lower ends of the corresponding first and second conductive posts to achieve electrical connection. At this time, the core can be... The charging operation is performed on the core. After charging is completed, the eighth drive unit moves the charging base downward to charge the next core. How the charging circuit board charges the core is a conventional technology in the field, so it will not be described in detail in this article. The discharge circuit board is provided with contacts adapted to the first and second conductive posts. When the ninth drive unit moves the discharge base upward, the discharge circuit board abuts against the lower ends of the corresponding first and second conductive posts to achieve electrical connection. At this time, the core can be discharged. After discharging is completed, the ninth drive unit moves the discharge base downward to discharge the next core. How the discharge circuit board discharges the core is a conventional technology in the field, so it will not be described in detail in this article.

[0031] A further feature of the present invention is that the feeding mechanism includes a mounting base, a feeding base, and a swing arm. The mounting base is fixedly mounted on the frame. The mounting base is provided with a receiving groove and a feeding groove, which are interconnected. The feeding groove has a feeding end near the rotating disk. The feeding base is guided and slidably mounted on the mounting base along the length of the feeding groove. A feeding block is fixedly or integrally mounted on the feeding base. The feeding block is slidably mounted in the feeding groove. The middle part of the swing arm is hinged to the feeding base. The swing arm is located above the feeding block. A clamping head is provided on the swing arm near the feeding block. The clamping head can clamp the core by swinging towards the side closer to the feeding block, and can release the core by swinging away from the feeding block. The feeding mechanism also includes a tenth driving unit for driving the feeding base to slide and an eleventh driving unit for driving the swing arm to swing.

[0032] By adopting the above scheme, when feeding is required, the core moves from the receiving slot into the feeding slot. At this time, the clamping head and the feeding block cooperate to clamp the core. The tenth drive unit drives the feeding seat to move towards the rotating disk, which can send the core to the clamping area of ​​the first conductive clamp and the second conductive clamp. Before the first conductive clamp and the second conductive clamp clamp the core, the core is not easy to fall off. After the first conductive clamp and the second conductive clamp clamp the core, the eleventh drive unit drives the swing arm to swing, so that the clamping head swings away from the feeding block. Then the tenth drive unit drives the feeding seat to move and reset. Due to the stop of the feeding block, the next core cannot enter the feeding slot. After the feeding block moves and resets, the next core moves into the feeding slot to perform the feeding operation on the next side. The structure is simple and the transmission is stable.

[0033] A further provision of the present invention is that the welding mechanism includes a placement seat, a first slide block, and a second slide block. The placement seat is slidably mounted on the frame in a vertical direction. The first and second slide blocks are slidably mounted on the placement seat in an X-axis direction. The first heating block is mounted on the first slide block, and the second heating block is mounted on the second slide block. The welding mechanism further includes a twelfth driving unit for driving the placement seat to move up and down, and a thirteenth driving unit for driving the first and second slide blocks to move towards or away from each other. The thirteenth driving unit includes a swing seat, a first connecting seat, a second connecting seat, and a first driving member. The middle position of the swing seat is rotatably mounted on the frame. The first connecting seat and the first... The slide block slides vertically, and the first connecting seat can drive the first slide block to slide along the X-axis. The first connecting seat is connected to the swing seat through the first pull rod. One end of the first pull rod is hinged to the first connecting seat, and the other end of the first pull rod is hinged to the upper end of the swing seat. The second connecting seat and the second slide block slide vertically, and the second connecting seat can drive the second slide block to slide along the X-axis. The second connecting seat is connected to the swing seat through the second pull rod. One end of the second pull rod is hinged to the second connecting seat, and the other end of the second pull rod is hinged to the lower end of the swing seat. The first driving member drives the swing seat to rotate, and the swing seat can drive the first connecting seat and the second connecting seat to move towards or away from each other through the first pull rod and the second pull rod.

[0034] By adopting the above scheme, the middle position of the swing seat is rotatably mounted on the frame via a rotating shaft. The axial direction of the rotating shaft is set along the Y-axis. The first driving member drives the swing seat to rotate. When the swing seat rotates forward, it pulls back the first pull rod and pushes out the second pull rod, which can drive the first connecting seat and the second connecting seat to move towards each other. When the swing seat rotates in reverse, it pushes out the first pull rod and pulls back the second pull rod, and the first connecting seat and the second connecting seat move in opposite directions. Since the first connecting seat and the first slide are in vertical sliding engagement, and the second connecting seat and the second slide are in vertical sliding engagement, the first slide and the second slide can move up and down and slide along the X-axis simultaneously without interfering with each other.

[0035] A further feature of the present invention is that the core feeding mechanism includes a feeding seat, an upper clamp, and a lower clamp. The feeding seat can be slidably mounted on the frame along the Y-axis direction. The frame is provided with a fourteenth driving unit that drives the feeding seat to move along the Y-axis direction. The upper clamp or the lower clamp can be slidably mounted on the feeding seat in the vertical direction. The corresponding lower clamp or the upper clamp is fixedly mounted on the feeding seat. The feeding seat is provided with a fifteenth driving unit that drives the upper clamp or the lower clamp to move up and down. The upper clamp and the lower clamp cooperate to transfer the core that has been energized on the rotating disk to the welding area.

[0036] By adopting the above scheme, the fourteenth drive unit drives the loading seat to move back and forth along the Y-axis. The upper clamp can be slidably set on the loading seat in the vertical direction, and the lower clamp is fixedly set on the loading seat. The fifteenth drive unit drives the upper clamp to move up and down. The upper clamp and the lower clamp cooperate to transfer the core that has been energized on the rotating disk to the welding area. This process is repeated, which can improve the efficiency of loading the core.

[0037] A further embodiment of the present invention is as follows: the frame is sequentially provided with a lead wire trimming mechanism, a lead wire spreading mechanism, and a lead wire tail loop cutting mechanism on one side of the conveying track. The lead wire trimming mechanism includes a second cutter and a seventh drive unit. The second cutter is slidably mounted on the frame in the vertical direction. The seventh drive unit drives the second cutter to move up and down, thereby trimming the two ends of the U-shaped lead wire. The lead wire spreading mechanism includes a spreading block and an eighth drive unit. The spreading block is slidably mounted on the frame in the Y-axis direction. The end of the spreading block is provided with a spreading head, and inclined surfaces are symmetrically arranged on the spreading head. The eighth drive unit drives the spreading block to slide in the Y-axis direction, thereby spreading the two ends of the U-shaped lead wire. The lead wire tail loop cutting mechanism includes a third cutter and a ninth drive unit. The third cutter is slidably mounted on the frame in the vertical direction. The ninth drive unit drives the third cutter to move up and down, thereby cutting off the U-shaped tail loop of the U-shaped lead wire.

[0038] By adopting the above scheme, after the lead strip is formed, the two ends of the U-shaped lead and the U-shaped tail ring are exposed on the paper strip. The conveyor rail will transport the lead strip to the lead trimming mechanism, where the second cutter can trim the two ends of the U-shaped lead. Then the conveyor rail will transport the lead strip to the lead spreading mechanism, where the spreading block can spread the two ends of the U-shaped lead. Finally, the conveyor rail will transport the lead strip to the lead tail ring cutting mechanism, where the third cutter can cut the U-shaped tail ring of the U-shaped lead. This can cut the lead on the lead strip for subsequent soldering operations.

The second drive unit drives the third pull rod 245 to move up and down. The second drive unit can be an external motor and an eccentric disk structure. The external motor drives the eccentric disk to make eccentric movements, thereby driving the third pull rod to move up and down. Of course, the second drive unit can also be a cylinder structure, as long as it can drive the pressure block to move up and down.

[0065] The paper tape feeding mechanism can convey the paper tape 91 from below the material distribution block 243 to the bonding area 12. The paper tape feeding mechanism includes a paper tape feeding wheel 211 and a first transmission wheel set. The first transmission wheel set includes a plurality of first transmission wheels 212, and each first transmission wheel 212 is spaced apart on the frame 1 along the X-axis direction.

[0070] The lead wire forming and pushing assembly 27 includes a base 271, a forming seat 272, a stop block 273, and a second drive unit. The base 271 is fixedly mounted on the frame 1. The forming seat 272 is slidably mounted on the base 271 along the Y-axis. The second drive unit can drive the forming seat 272 to slide along the Y-axis. A cavity 2721 is provided on the forming seat 272. The stop block 273 is placed at the cavity 2721.
