Description

Technical Field

[0001] This utility model belongs to the field of capacitor manufacturing technology, specifically relating to an automatic lead-cutting and bending device for capacitors. Background Technology

[0002] In the manufacturing process of electronic components, capacitors are widely used as basic components in various circuit boards. To adapt to the process requirements of different installation scenarios, capacitor leads need to be trimmed and bent to meet the spacing, height, and shape standards for PCB board soldering.

[0003] Traditional processing methods employ automated lead-cutting equipment, followed by bending equipment to plastically deform the cut capacitors to meet welding or installation requirements. In this production model, capacitors need to be transferred between the automated lead-cutting and bending equipment. The mismatch in processing speeds between these two systems leads to material shortages, impacting production capacity. Furthermore, the transfer process relies on manual loading, increasing labor costs.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides an automatic lead-cutting and bending device for capacitors, which realizes automatic feeding, automatic lead cutting, and automatic bending of bulk capacitors, reduces transfer time, increases production capacity, and reduces labor costs.

[0006] Technical Solution: To achieve the above objectives, this utility model provides an automatic lead-cutting and bending device for capacitors, including a frame. A feeding mechanism and a lead-cutting and bending mechanism are connected to the top surface of the frame. The feeding mechanism has a discharge port connected to the lead-cutting and bending mechanism. The lead-cutting and bending mechanism includes a drive assembly, which drives a first lead-cutting mechanism, a second lead-cutting mechanism, and a bending mechanism. A transfer mechanism is located on the upper side of the drive assembly, which sequentially transfers capacitors from the feeding mechanism to the first lead-cutting mechanism, the second lead-cutting mechanism, and the bending mechanism. A discharge plate is located on the side of the bending mechanism away from the second lead-cutting mechanism, and the discharge plate is inclined downwards away from the bending mechanism. This utility model is used for lead-cutting and bending of square capacitors. The described feeding mechanism uses a vibratory feeder, widely used in the field of automation, to achieve automatic sorting and directional transport of capacitors. The production process includes: pouring bulk capacitors into a feeding mechanism; the feeding mechanism automatically sorts and orients the capacitors to a lead-cutting and bending mechanism; a transfer mechanism within the lead-cutting and bending mechanism sequentially transfers the capacitors from the feeding mechanism to a first lead-cutting mechanism, which cuts the capacitor leads to the designed length; then, the transfer mechanism transfers the capacitors from the first lead-cutting mechanism to a second lead-cutting mechanism, which trims the capacitors to the designed shape; next, the transfer mechanism transfers the capacitors from the second lead-cutting mechanism to a bending mechanism, which bends the capacitor leads; finally, the transfer mechanism transfers the capacitors from the bending mechanism to an unloading plate, where they fall into a material box under the guidance of the unloading plate. This process achieves automatic sorting and orienting of bulk capacitors, automatic lead cutting and bending, ensuring that the capacitor leads meet design requirements, ensuring consistency in lead cutting and bending, improving capacitor quality, increasing production efficiency, and reducing labor costs.

[0007] Furthermore, in the aforementioned automatic shearing and bending device for capacitors, the transfer mechanism includes a crossbeam connected to the top surface of the frame via a bracket. A sliding plate is slidably connected to the top surface of the crossbeam, and the sliding plate is slidably positioned from the first shearing mechanism towards the bending mechanism. A transverse drive mechanism is provided on the side of the sliding plate away from the feeding mechanism, driving the sliding plate to reciprocate along the first shearing mechanism, the second shearing mechanism, and the bending mechanism. A gripper is connected to the side of the sliding plate near the first shearing mechanism, and a clamping drive mechanism is connected to the side of the sliding plate away from the first shearing mechanism. The clamping drive mechanism and the gripper are driven together, and the clamping drive mechanism drives the gripper to clamp the capacitor. The transverse drive mechanism is a cylinder, with the cylinder shaft driven to the sliding plate. The cylinder shaft is connected to the top surface of the frame via a bracket, and the cylinder shaft extends and retracts to drive the sliding plate to reciprocate along the first shearing mechanism towards the bending mechanism.

[0008] Furthermore, in the aforementioned automatic lead-cutting and bending device for capacitors, the gripper includes a fixed gripper arm and a movable gripper arm. The fixed gripper arm is connected to the side wall of the slide plate, and the movable gripper arm has an inverted L-shaped cross-section. The upper end of the movable gripper arm is longer than the short side of the slide plate, and the upper end of the movable gripper arm is slidably connected to a groove provided on the top of the slide plate. A fixing plate is connected to the top of the slide plate, and the fixing plate restricts the upper end of the movable gripper arm within the groove on the top of the slide plate. The upper end of the movable gripper arm is driven to a drive shaft of a clamping drive mechanism. The clamping drive mechanism is a cylinder. This invention uses a fixed gripper arm and a movable gripper arm, and drives the movable gripper arm to move through the clamping drive mechanism to grasp or release the capacitor.

[0009] Furthermore, in the aforementioned automatic lead-cutting and bending device for capacitors, the grippers include a first gripper, a second gripper, a third gripper, and a fourth gripper. The first gripper, the second gripper, the third gripper, and the fourth gripper are arranged sequentially along the slide plate. The second gripper, the third gripper, and the fourth gripper are correspondingly located on the upper side of the first lead-cutting mechanism, the second lead-cutting mechanism, and the bending mechanism. The distance between the second gripper, the third gripper, and the fourth gripper is the same as the distance between the first lead-cutting mechanism, the second lead-cutting mechanism, and the bending mechanism. A transplanting plate is connected to the side of the first gripper away from the second gripper. The transplanting plate is respectively connected to the fixed claw arm and the movable claw arm of the first gripper. The fixed claw arm and the movable claw arm respectively drive the transplanting plate to clamp the capacitor. The distance between the transplanting plate and the second gripper is set as the distance between the second gripper and the third gripper. This invention uses four grippers: a first gripper, a second gripper, a third gripper, and a fourth gripper. During production, a lateral drive mechanism drives a sliding plate to move toward a feeding mechanism. When the sliding plate triggers a limit switch located near the feeding mechanism on the side of the crossbeam, the lateral drive mechanism stops. At this time, the transfer plate of the first gripper is positioned above the discharge port of the feeding mechanism, the second gripper is positioned above the first shearing mechanism, the third gripper is positioned above the second shearing mechanism, and the fourth gripper is positioned above the bending mechanism. The clamping drive mechanism drives the movable claw arm to move toward the fixed claw arm. The first gripper clamps the capacitor to be processed on the feeding mechanism, the second gripper clamps the capacitor on the first shearing mechanism, the third gripper clamps the capacitor on the second shearing mechanism, and the fourth gripper clamps the capacitor on the bending mechanism.

[0010] The lateral drive mechanism drives the slide plate to move away from the feeding mechanism. The slide plate triggers a limit switch on the side of the crossbeam away from the feeding mechanism, stopping the lateral drive mechanism. At this time, the transfer plate of the first gripper is above the first shearing mechanism, the second gripper is above the second shearing mechanism, the third gripper is above the bending mechanism, and the fourth gripper is above the unloading plate. The clamping drive mechanism drives the movable claw arm to move away from the fixed claw arm. The first gripper places the capacitor to be processed onto the first shearing mechanism, the second gripper releases the capacitor onto the second shearing mechanism, the third gripper releases the capacitor onto the bending mechanism, and the fourth gripper releases the capacitor onto the unloading plate. Repeating the above steps achieves automatic capacitor feeding, automatic shearing, and automatic bending, reducing production steps, reducing material handling, increasing capacity, and reducing labor costs.

[0011] Furthermore, in the aforementioned automatic lead-cutting and bending device for capacitors, the driving assembly includes a first driving plate and a second driving plate. The first and second driving plates are rectangular, and their ends are slidably connected to the top surface of the frame via slide rails. Two slide rails are provided and arranged in parallel. A first driving cylinder and a second driving cylinder are connected to the top surface of the frame. The first driving cylinder is located on the side of the first driving plate away from the second driving plate, and its cylinder shaft is driven by the first driving plate. The second driving cylinder is located on the side of the second driving plate away from the first driving plate, and its cylinder shaft is driven by the second driving plate. The first and second driving cylinders respectively drive the first and second driving plates to move closer or separate. In this invention, the first and second driving cylinders drive the first and second driving plates to move closer and separate, thereby driving the first lead-cutting mechanism, the second lead-cutting mechanism, and the bending mechanism to process the capacitor.

[0012] Furthermore, in the aforementioned automatic lead-cutting and bending device for capacitors, the first lead-cutting mechanism includes a first main blade holder connected to the top surface of the first drive plate and a first auxiliary blade holder connected to the top surface of the second drive plate. A first support plate is connected to the side of the first main blade holder near the first auxiliary blade holder, extending towards the first auxiliary blade holder and supporting the capacitor. A slotted plate is connected to the top surface of the first support plate, with a first main cutter connected within a slot. A pressure block is connected to the top surface of the slotted plate, pressing and fixing the first main cutter within the slotted plate. A first auxiliary cutter is connected to the top surface of the first auxiliary blade holder, with its blade edge positioned opposite to that of the first main cutter. When the first drive cylinder drives the first drive plate to move towards the second drive plate, and the second drive cylinder drives the second drive plate to move towards the first drive plate, the first main blade holder and the first auxiliary blade holder abut against each other to cut the capacitor leads, ensuring consistent lead lengths. This facilitates subsequent secondary lead cutting and bending, ensuring capacitor welding quality and enabling automated production. The first main cutter is pressed and fixed in the slot plate by the pressure block. When the first main cutter wears out, it is easy to maintain the first main cutter and improve the convenience of maintenance.

[0013] Furthermore, in the aforementioned automatic lead-cutting and bending device for capacitors, the second lead-cutting mechanism includes: a second main blade holder connected to the top surface of the first drive plate, and a second auxiliary blade holder connected to the top surface of the second drive plate. The second main blade holder is near the second auxiliary blade holder, and a second support plate is connected to one side of it. The second support plate extends towards the second auxiliary blade holder and supports the capacitor. A second main cutter is connected to the top surface of the second support plate. A second auxiliary cutter is connected to the side of the second auxiliary blade holder near the second main blade holder. The blade of the second main cutter is V-shaped, and the blades of the second auxiliary cutter and the second main cutter are correspondingly arranged. The second main blade holder is L-shaped, and a first connecting block is connected to the top of the second main blade holder. A first screw is movably connected to the first connecting block. The first screw is vertically arranged and passes through the first connecting block and connects to the horizontal end of the second main blade holder. The second support plate is slidably connected to a waist hole provided at the vertical end of the second main blade holder. The second support plate passes through the vertical end of the second main blade holder and is drivenly connected to the first screw. A first hand-tightening part is connected to the upper end of the first screw. The first lead-cutting mechanism leaves the capacitor leads with flat ends after cutting, affecting capacitor positioning and soldering. A second lead-cutting mechanism is then implemented to perform a secondary lead-cutting. Specifically, this involves a first drive cylinder moving the first drive plate towards the second drive plate, and a second drive cylinder moving the second drive plate towards the first drive plate. The second main cutter and the second auxiliary cutter then come into contact and perform a secondary cut on the capacitor leads. The V-shaped blades cut the capacitor leads into pointed tips, allowing for better insertion into the circuit board and improving positioning accuracy. The pointed shape also facilitates solder flow and adhesion, reducing soldering defects and ensuring soldering quality and reliability. Simultaneously, turning the first hand-tightening unit rotates the first screw, which in turn moves the second support plate up and down, adjusting the position of the first main cutter to ensure the effective lead-cutting. The second auxiliary cutter is connected to a slot in the second auxiliary cutter holder via fasteners. Adjusting the height of the second auxiliary cutter adjusts the lead-cutting height to meet different lead-cutting requirements.

[0014] Furthermore, in the aforementioned automatic lead-cutting and bending device for capacitors, the bending mechanism includes: a main bending seat connected to the top surface of the first drive plate, and a secondary bending seat connected to the top surface of the second drive plate. The main bending seat is connected to a bending support plate, which extends towards the secondary bending seat and supports the capacitor. A main bending portion is connected to the top surface of the bending support plate. A secondary bending portion is connected to the side of the secondary bending seat near the main bending seat. The main bending seat and the secondary bending portion are correspondingly arranged, with a vertical gap between them. The main bending seat is L-shaped, and a second connecting block is connected to the top of the main bending seat. A second screw is movably connected to the second connecting block. The second screw is vertically arranged and passes through the second connecting block to connect to the horizontal end of the main bending seat. The bending support plate is slidably connected to a waist hole provided at the vertical end of the main bending seat. The bending support plate passes through the vertical end of the main bending seat and is driven by the second screw. A second hand-tightening portion is connected to the upper end of the second screw. After the capacitor leads are cut a second time by the second lead-cutting mechanism, the bending mechanism bends the capacitor leads. Specifically, a first drive cylinder drives a first drive plate to move towards a second drive plate, and a second drive cylinder drives the second drive plate towards the first drive plate. The main bending seat and the secondary bending section alternate, bending the capacitor leads. Simultaneously, the second hand-tightening part is turned, causing the second screw to rotate, driving the bending support plate to move and adjusting the gap between the main bending seat and the secondary bending section to meet the requirements of leads of different thicknesses, improving equipment adaptability. The secondary bending seat is connected to the waist hole of the secondary bending seat by fasteners. When the bending length needs to be adjusted, the height of the secondary bending seat is adjusted, improving equipment flexibility.

[0015] Furthermore, in the aforementioned automatic lead-cutting and bending device for capacitors, the feeding mechanism is a vibratory feeder, comprising an inner spiral track and an outer spiral track. The outer spiral track is connected to the lead-cutting and bending mechanism via a feeding channel. The capacitor is poured into the vibratory feeder and, under vibration, rises along the inner spiral track, entering the outer spiral track. The outer spiral track is spirally inclined downwards towards the feeding channel, and the capacitor enters the feeding channel along the outer spiral track, finally being transferred from the feeding channel into the lead-cutting and bending mechanism. The vibratory feeder is a commonly used automatic feeding device, which will not be described in detail here.

[0016] Furthermore, in the aforementioned automatic lead-cutting and bending device for capacitors, adjustable feet are connected to the bottom of the frame, and these adjustable feet are connected to the four corners of the frame. The adjustable feet are connected by bolts, and the frame is adjusted by adjusting the bolts to bring the top surface of the frame into a horizontal position.

[0017] As can be seen from the above technical solution, this utility model has the following beneficial effects: This utility model is an automatic lead-cutting and bending device for capacitors, which realizes the automatic sorting and directional transmission of bulk capacitors, automatically cuts and bends the leads of the capacitors, ensures that the capacitor leads meet the design requirements, ensures the consistency of lead cutting and bending, improves capacitor quality, improves production efficiency, and reduces labor costs.
