Description

Technical Field

[0001] This invention relates to the field of capacitor technology, and in particular to a lead wire processing device for 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] Before soldering the pins, several pins need to be attached to a paper tape at intervals. This allows the pin tape to move the pins to the soldering area so that conductive pins can be soldered to the two conductive ends of the core. To improve processing efficiency, long conductive leads need to be fed into the paper tape, cut to appropriate lengths, and then U-bent. The bent leads are then moved to the attaching area, while the paper tape and adhesive tape are automatically conveyed to the attaching area. The adhesive tape is used to attach the U-shaped leads to the paper tape, forming a lead tape to meet the subsequent soldering requirements. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a lead strip processing device for capacitor production equipment. It can automatically feed leads, paper tape, and adhesive tape, cut long leads into appropriate lengths, bend the cut leads into U-shapes, and then transfer the bent leads to the bonding area. The U-shaped leads are then bonded to the paper tape with adhesive tape to form lead strips, thus realizing automated processing of lead strips for subsequent soldering operations.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a lead wire processing device for capacitor production equipment, comprising a frame, characterized in that: the frame is provided with a paper tape feeding mechanism, an adhesive tape feeding mechanism, a lead wire feeding mechanism, a pressing mechanism, and a conveying track, the conveying track being arranged along the X-axis direction, and the lead wire feeding mechanism comprising, sequentially arranged along the X-axis direction, a lead wire conducting component, a lead wire traction component, a lead wire cutting component, and a lead wire forming and pushing component.

[0007] 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.

[0008] The paper tape feeding mechanism can convey the paper tape from below the dispensing block to the bonding area;

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

[0010] The lead conduction assembly can guide and transmit the lead to the lead traction assembly;

[0011] The lead wire traction assembly includes a traction seat, a second drive unit, a first clamping plate, a second clamping plate, and a third drive unit. The traction seat is slidably mounted on the frame along the X-axis direction. The second drive unit drives the traction seat to reciprocate along the X-axis direction. The first clamping plate and the second clamping plate form a clamping cavity for clamping the lead wire. The first clamping plate and / or the second clamping plate are slidably mounted on the traction seat along the Y-axis direction. The third drive unit can drive the first clamping plate and the second clamping plate to clamp or release the lead wire.

[0012] The lead wire cutting assembly includes a cutter holder, a first cutter, and a fourth 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 fourth drive unit can drive the first cutter to slide along the Y-axis direction, thereby causing the first cutter to cut the lead wire.

[0013] The lead forming and pushing assembly includes a base, a forming seat, a stop block, and a fifth 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 fifth 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.

[0014] By adopting the above scheme, when the first and second clamping plates clamp the lead wire, the second drive unit moves the traction seat towards the cutter seat, thus pulling the lead wire to the cutter seat. Then, the first cutter cuts the lead wire to a suitable length. When a section of lead wire needs to be cut off, the first and second clamping plates release the lead wire. At this time, the second drive unit moves the traction seat away from the cutter seat, then the first and second clamping plates clamp the lead wire again, and the second drive unit moves the traction seat towards the cutter seat again. This cycle repeats, enabling automatic lead wire loading and cutting of the lead wire to a suitable length. The length of the cut lead wire is the travel length of the traction seat along the X-axis. The lead wire will not fall off due to the stop effect of the lead wire hole. Meanwhile, the forming seat moves towards the cutter seat under the drive of the fifth drive unit. After moving backward, the two contact blocks on the forming seat press against both ends of the lead wire, while the middle of the lead wire is stopped by the stop block, thus forming a U-shaped lead wire. Then, the forming seat moves forward under the drive of the fifth 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 material distribution block to the bonding area, and the adhesive tape is conveyed from above the material 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 down, and by pressing against the adhesive tape, the U-shaped lead wire can be adhered to the paper tape through the adhesive tape to form a lead wire strip. With automated processing, the U-shaped lead wires are distributed at intervals on the lead wire strip, realizing the automated processing of the lead wire strip for subsequent welding operations.

[0015] A further feature of the present invention is that: the bottom of the cavity has grooves on the two opposite inner walls, and the ends of the two abutting blocks are respectively provided with guide surfaces, which are inclined toward one side of the grooves.

[0016] By adopting the above scheme, the guide surface can drive the lead wire to move down during the bending process, so that the U-shaped lead wire is placed in the groove. This makes it easy for the forming seat to move the U-shaped lead wire to the support platform. The structure is simple and the design is reasonable.

[0017] A further feature of the present invention is that the stop block is movably mounted on the frame in a vertical direction, and a sixth drive unit is provided on the frame to drive the stop block to move up and down. When the stop block moves down, it can press the U-shaped lead wire into the groove.

[0018] By adopting the above scheme, the sixth drive unit drives the stop block to move down, and the stop block can press the U-shaped lead wire into the groove. Then the stop block moves up to reset. This ensures that the formed U-shaped lead wire will be transferred to the support table by the forming seat, and can work continuously. The structure is simple and the design is reasonable.

[0019] A further feature of the present invention is that the first clamping plate is slidably disposed on the traction seat along the Y-axis direction, the second clamping plate is fixedly or integrally disposed on the traction seat, the traction seat is provided with a first elastic element that drives the first clamping plate to move toward the side closer to the second clamping plate, and the third driving unit can drive the first clamping plate to move away from the second clamping plate.

[0020] By adopting the above scheme, when the traction seat moves away from the cutter seat, the third 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 third drive unit removes the force on the first clamping plate, and the first elastic element 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 cutter seat, which can pull and transmit the lead wire. The structure is simple and the design is reasonable.

[0021] A further feature of the present invention is that the second drive unit includes a drive disk, a transmission rod, and a motor. The drive disk is rotatably mounted on the frame, and the central axis of the drive disk is set along the Y-axis. The drive disk has a first hinge shaft at a position offset from its central axis. The traction seat has a second hinge shaft. One end of the transmission rod is hinged to the first hinge shaft, and the other end of the transmission rod is hinged to the second hinge shaft. The motor drives the drive disk to rotate, and the drive disk drives the traction seat to reciprocate along the X-axis direction via the transmission rod.

[0022] By adopting the above scheme, the drive disc drives the first hinge shaft to make eccentric motion, and the first hinge shaft can drive the traction seat to slide back and forth along the X-axis direction through the transmission rod. The structure is simple and the transmission is stable.

[0023] A further feature of the present invention is that the third driving unit includes a transmission block and a driving member. The transmission block is slidably disposed on the frame along the Y-axis direction. The driving member can drive the transmission block to slide along the Y-axis direction. The transmission block can abut against the first clamping plate, thereby driving the first clamping plate to move closer to the second clamping plate.

[0024] By adopting the above scheme, when the traction seat moves away from the cutter seat, the driving component can drive the transmission block to abut against the first clamping plate, releasing the clamping of the lead wire. When the traction seat moves into position, the driving component can drive the transmission block away from the first clamping plate. Under the action of the first elastic element, the first clamping plate moves towards the side closer to the second clamping plate, thereby clamping the lead wire. Then the traction seat moves towards the cutter seat, which can pull and transmit the lead wire. The structure is simple and the control is convenient.

[0025] A further feature of the present invention is that the frame is provided with a clamping mechanism for clamping the lead wire between the traction seat and the cutter seat. The clamping mechanism includes a first pressure plate and a second pressure plate. The first pressure plate is fixedly mounted on the frame, and the second pressure plate is movably mounted on the frame along the Y-axis direction. The second pressure plate can press the lead wire against the first pressure plate.

[0026] By adopting the above scheme, when the traction seat moves away from the cutter seat, the second pressure plate can press the lead wire against the first pressure plate, thus preventing the traction seat from pulling the lead wire backward. The structure is simple and the design is reasonable.

[0027] A further feature of the present invention is that: a movable seat is fixedly or integrally provided on the transmission block, the second pressure plate is telescopically disposed on the movable seat along the Y-axis direction, the movable seat is provided with a second elastic element that drives the second pressure plate to move closer to the first pressure plate, and also includes a limiting element that restricts the second pressure plate from disengaging from the movable seat.

[0028] By adopting the above scheme, the transmission block can not only drive the first clamping plate to loosen its grip on the lead wire, but also drive the second pressure plate to press the lead wire against the first pressure plate, which simplifies the driving structure. In addition, the second elastic element plays a buffering role to prevent the second pressure plate from damaging the first pressure plate. The limiting element can restrict the second pressure plate from disengaging from the movable seat. The structure is simple and the design is reasonable.

[0029] A further provision 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.

[0030] 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.

[0031] A further embodiment of the present invention is as follows: the paper tape feeding mechanism includes a paper tape feeding wheel and a first transmission wheel set; the adhesive tape feeding mechanism includes an adhesive tape feeding wheel and a second transmission wheel set; the first transmission wheel set is located below the second transmission wheel set; the lead wire conduction assembly includes a horizontal wheel set and a vertical wheel set; the horizontal wheel set includes two sets of first guide wheels, each first guide wheel being spaced apart along the X-axis direction, and the axial direction of the first guide wheels being arranged along the vertical direction; the vertical wheel set includes two sets of second guide wheels, each second guide wheel being spaced apart along the X-axis direction, and the axial direction of the second guide wheels being arranged along the Y-axis direction.

[0032] By adopting the above scheme, the first transmission wheel group includes several first transmission wheels, each of which is spaced apart on the frame along the X-axis direction to play a transmission role. The second transmission wheel group includes several second transmission wheels, each of which is spaced apart on the frame from high to low along the X-axis direction to play a transmission role. The lead wire is guided and transmitted along the first guide wheel and the second guide wheel. The structure is simple and the position design is reasonable.
