Description

Technical Field

[0001] This utility model relates to the field of capacitor processing technology, specifically to a capacitor cutting and shaping machine. Background Technology

[0002] In the field of electronic component manufacturing, capacitors are common components, and their leads need to be cut and bent before they can be mounted on circuit boards. In the current technology, the cutting and bending of capacitor leads are usually done manually or with different equipment. Some small enterprises rely on simple cutting fixtures to cut the capacitor leads, and then use manual labor or bending equipment to bend the capacitor leads.

[0003] Traditional manual bending operations are affected by various human factors, resulting in low processing efficiency and excessively high labor costs in capacitor processing. Although existing bending equipment can reduce the use of manual labor to some extent, it still requires manual re-clamping of the cut capacitor onto the bending equipment, resulting in two clamping operations, which also affects processing efficiency. Especially for capacitors that require bending one lead while only cutting the other, traditional processing methods are inefficient, complex, and cannot meet the high-efficiency production requirements of large-scale factories. Utility Model Content

[0004] In order to solve the technical problems existing in the background art, this utility model proposes a capacitor cutting and shaping machine.

[0005] This utility model proposes a capacitor cutting and shaping machine, including a frame, a lower cutter, an upper cutter group, and a first drive assembly. The frame has a processing area, the lower cutter is fixed in the processing area of ​​the frame, the upper cutter group has a first upper cutter and a second upper cutter arranged side by side, and a block on the lower cutter. The first upper cutter head is pushed down by the first drive assembly to first cooperate with the cutting edge of the lower cutter to cut the first lead of the capacitor, and then cooperate with the block to bend and cut the first lead of the capacitor. The second upper cutter head is pushed down by the first drive assembly to cooperate with the cutting edge of the lower cutter to cut the second lead of the capacitor.

[0006] Preferably, the first upper cutting blade head is pushed down by the first drive group to first cooperate with the lower cutting blade edge to cut off the first lead of the capacitor and then cooperate with the block to bend the first lead of the capacitor. Specifically, when the lower cutting blade edge of the first upper cutting blade head approaches the lower cutting blade edge and forms a relative displacement, it cuts the first lead of the capacitor located between the first upper cutting blade head and the lower cutting blade edge. The lower cutting blade head then squeezes the cut first lead of the capacitor into the compression gap between the first upper cutting blade head and the block to bend the cut first lead of the capacitor.

[0007] Preferably, the first upper cutter head has a pre-bent portion and a cutting portion arranged sequentially along its length direction. The pre-bent portion and the cutting portion have a height difference in the vertical direction. The cutting portion constitutes the cutting edge of the first upper cutter head for cutting off the first pin of the capacitor. The block and the pre-bent portion of the first upper cutter head are arranged opposite each other in the vertical direction to form the extrusion gap between the downwardly moving pre-bent portion and the block.

[0008] Preferably, the second upper cutter head has a flat cutting edge, and the second upper cutter head cooperates with the lower cutter to cut off the second pin of the capacitor. Specifically, when the flat cutting edge of the lower cutter head moves downward and approaches the cutting edge of the lower cutter head and forms a relative displacement, it cuts the second pin of the capacitor located between the flat cutting edge of the second upper cutter head and the cutting edge of the lower cutter head.

[0009] Preferably, it further includes a feeding mechanism, which has a first rod, a first plate, and a second driving assembly. The first rod is located on the first plate, and the second driving assembly has a first driving unit and a second driving unit. The first rod is first driven by the first driving unit to move downward until it is inserted into the through hole of the capacitor strip located on the first plate, and then driven by the second driving unit to move the capacitor strip horizontally to achieve feeding.

[0010] Preferably, the feeding mechanism further includes a second rod and an elastic reset member. The elastic reset member is connected to the second rod and pushes the second rod to have an upward movement tendency. The diameter of the second rod is consistent with the diameter of the through hole of the capacitor strip. The elastic reset member pushes the second rod to insert into the through hole of the capacitor strip. The second rod is located on the downward movement path of the first rod so as to abut against the first rod and be pushed down until the first rod is inserted into the through hole of the capacitor strip.

[0011] Preferably, the feeding mechanism further includes a second plate, which is arranged parallel above the first plate. A limiting gap is provided between the first plate and the second plate for the capacitor strip to pass through. The first plate has a strip-shaped through hole adapted to the first rod, and the first rod moves through the strip-shaped through hole in a movable manner.

[0012] Preferably, the elastic reset member has a third plate, a third rod, and a spring. The second rod is fixed on the third plate, and the third plate is arranged on the side of the second plate away from the first plate. The third plate is penetrated by the third rod and can move up and down along the third rod. The spring is sleeved on the outside of the third rod and is located on the side of the third plate away from the second plate. The two ends of the spring abut against the surface of the third plate and the surface of the machine frame processing area, respectively, to apply an upward force to the third plate.

[0013] Preferably, both the first drive assembly and the second drive assembly are linear drive mechanisms, which are fluid drive cylinders or electric linear actuators.

[0014] Preferably, the frame also has a recycling area, in which a hopper is installed, and an air pipe is provided in the frame processing area. The air outlet of the air pipe is directed horizontally from the cutting edge of the lower cutter towards the hopper inlet to blow the cut and bent capacitor into the hopper.

[0015] In this invention, through the coordinated action of the first upper and lower cutters and the block, the first lead of the capacitor can be bent immediately after being cut off. Then, the second lead is cut off by the cooperation between the second upper and lower cutters. The entire processing is continuous and automatic, and the cutting and bending of the capacitor lead are completed in one go, avoiding the cumbersome operation of traditional multi-step and multi-equipment processing, and greatly improving production efficiency. At the same time, the bending and cutting operations of this invention are all completed automatically by machinery, which can also greatly reduce labor input costs and reduce the impact of human factors on production efficiency, which helps to further improve processing efficiency.

[0026] Reference Figure 1 This utility model proposes a capacitor cutting and shaping machine, including a frame 1. The frame 1 has a processing area and a recycling area. A material bin is provided on one side of the frame 1, and rolled capacitor strips are placed on the material bin. Figure 9 As shown: The capacitor strip has capacitors arranged at equal intervals, and the two leads of the capacitors are connected to the capacitor strip.

[0027] It also includes a feeding mechanism 5 for automatically conveying capacitor strips, specifically such as... Figure 7 As shown: The feeding mechanism 5 has a first rod 53, a second rod 54, a second drive assembly 56, an elastic reset member 55, and a first plate 51 and a second plate 52 arranged in parallel. A limiting gap is provided between the first plate 51 and the second plate 52 for the capacitor strip to pass through. When feeding, the capacitor strip needs to be manually inserted into the limiting gap. The setting of the limiting gap can restrict the movement position of the capacitor strip between the first plate 51 and the second plate 52, which helps to keep the movement direction of the capacitor strip from deviating.

[0028] The first plate 51 is provided with a strip-shaped through hole adapted to the first rod 53. The first rod 53 is movably inserted through the strip-shaped through hole. The strip-shaped through hole allows the first rod 53 to push the capacitor strip to move within the limiting gap. The first rod 53 is connected to the second drive assembly 56 and is driven by the second drive assembly 56 to perform lifting and lowering motion in the vertical plane and reciprocating motion in the horizontal direction. The second rod 54 is movably inserted through the second plate 52 and the capacitor strip through hole to position the capacitor strip. The elastic reset member 55 is connected to the second rod 54 to give the second rod 54 an upward movement tendency. The elastic reset member 55 ensures that the initial position of the second rod 54 is maintained in the state of penetrating the second plate 52. Therefore, during the process of inserting the capacitor strip into the limiting gap, it is necessary to manually press the elastic reset member 55 downward to move the second rod 54 downward until the top of the second rod 54 is submerged in the second plate 52. At the same time, the capacitor strip is pushed along the limiting gap until the through hole on the limiting strip is aligned with the second rod 54. At this time, the limiting of the elastic reset member 55 is manually released, and the second rod 54 can penetrate the through hole of the capacitor strip under the pushing action of the elastic reset member 55, thereby achieving the positioning of the capacitor strip.

[0029] In this embodiment, the structure of the elastic reset member 55 is as follows: Figure 8As shown: The machine comprises a third plate 551, a third rod 552, and a spring 553. A second rod 54 is fixed to the third plate 551. The third plate 551 is located on the side of the second plate 52 away from the first plate 51. The third plate 551 is penetrated by the third rod 552 and can move up and down along the third rod 552. The spring 553 is sleeved on the third rod 552 and located on the side of the third plate 551 away from the second plate 52. Both ends of the spring 553 abut against the surface of the third plate 551 and the surface of the processing area of ​​the frame 1, respectively, to apply force to the third plate 551. The upward force; the side wall of the third plate 551 is equipped with an operating rod for moving the third plate 551 downward. Therefore, when loading materials, the operator can move the operating rod downward to move the third plate 551 downward, so that the moving third plate 551 can move the second rod 54 downward. At the same time, the third plate 551 will also compress the spring 553 downward during the downward movement. Therefore, when the operator releases the fixing of the operating rod, the compressed spring 553 will push the third plate 551 and the second rod 54 upward to reset under its own elastic force.

[0030] After the capacitor strip is positioned, the sensor on the processing area of ​​the frame 1 detects the presence of the capacitor strip on the feeding mechanism 5 and immediately drives the first rod 53 to move downward through the first drive unit of the second drive assembly 56. The second rod 54 is arranged on the downward path of the first rod 53. Therefore, after the first rod 53 moves downward, it will contact the second rod 54 that passes through the through hole of the capacitor strip. As the first rod 53 continues to move downward, it will also push the second rod 54 to move downward synchronously with the first rod 53 until the second rod 54 is removed from the through hole of the capacitor strip. Then the second drive... The second drive unit of component 56 drives the first rod 53 to move the capacitor strip horizontally forward by one step along the strip-shaped through hole. At this time, the second rod 54 will be pushed back into the other through hole of the capacitor strip by the elastic reset member 55. Then the first drive unit of the second drive component 56 drives the first rod 53 to move upward. The second drive unit of the second drive component 56 drives the first rod 53 to move horizontally backward to reset. Then the first drive unit of the second drive component 56 drives the first rod 53 to repeat the above actions to realize automatic intermittent step feeding.

[0031] During the feeding process described above, the second drive component 56 is a linear drive mechanism. This linear drive mechanism can be either a fluid drive cylinder or an electric linear actuator. In this embodiment, two cylinders are used to drive the first rod 53 to perform lifting and horizontal movements respectively. Cylinders have the advantages of low cost and high speed. Moreover, the movement of the first rod 53 is a short-stroke linear movement, which does not require high precision but does require high response speed. Using cylinders as a power source is an economical and efficient choice.

[0032] After feeding, the two leads of the capacitor on the capacitor strip need to be cut and bent, such as... Figure 1 As shown, the capacitor cutting and shaping machine is also equipped with a lower cutter 2, a block 8, an upper cutter group 3, and a first drive assembly 4 for cutting bent capacitor leads. The lower cutter 2 is fixed to the processing area of ​​the frame 1, and the specific structure of the upper cutter group 3 is as follows: Figure 3 As shown: The upper cutting blade group 3 has a first upper cutting blade 31 and a second upper cutting blade 32 arranged side by side, and the block 8 is mounted on the lower cutting blade 2;

[0033] The first upper cutter 31, driven by the first drive group 4, moves downward to first engage with the lower cutter 2 to cut the first lead of the capacitor, and then engages with the block 8 to bend and cut the first lead of the capacitor. Figure 4-6 As shown, the first upper cutter 31 has a pre-bending portion 311 and a cutting portion 312 arranged sequentially along its length. The pre-bending portion 311 and the cutting portion 312 have a height difference in the vertical direction, and the lowest point of the pre-bending portion 311 is higher than the cutting edge of the cutting portion 312. This allows the cutting portion 312 of the downward-moving first upper cutter 31 to first approach the cutting edge of the lower cutter 2 and form a relative displacement, thus shearing the first lead of the capacitor located between the cutting edge of the first upper cutter 31 and the cutting edge of the lower cutter 2, thereby cutting off the first lead of the capacitor. Then, the cut first lead of the capacitor is bent by the pre-bending portion 311. The bending process is as follows: the block 8 and the pre-bending portion 311 of the first upper cutter 31 are arranged opposite each other in the vertical direction to form a compression gap between the downward-moving pre-bending portion 311 and the block 8. When the pre-bending portion 311 moves downward, it presses the cut first lead of the capacitor into the compression gap to produce a plastic bend. Figure 10 As shown in the image.

[0034] The second upper cutter 32 is pushed downward by the first drive group 4 to cooperate with the cutting edge of the lower cutter 2 to cut off the second pin of the capacitor. Specifically, as shown below... Figure 3 As shown: The second upper cutter 32 has a flat cutting edge. The principle of the second upper cutter 32 cutting edge and the lower cutter 2 cutting edge cutting the second pin of the capacitor is as follows: When the flat cutting edge of the second upper cutter 32 moving downward approaches the cutting edge of the lower cutter 2 and forms a relative displacement, it cuts the second pin of the capacitor located between the flat cutting edge of the second upper cutter 32 and the cutting edge of the lower cutter 2, thereby cutting off the second pin of the capacitor.

[0035] In this embodiment, the first driving component 4 that drives the upper cutter group 3 to move downward is a linear drive mechanism. This linear drive mechanism can be either a fluid drive cylinder or an electric linear actuator. Since the upper cutter group 3 has a short travel stroke and low accuracy requirements in this embodiment, an economical and efficient cylinder is chosen as the power source to move the first upper cutter 31 and the second upper cutter 32 via... Figure 3The mounting plate is connected to the cylinder output terminal. Taking the first drive assembly 4 using a cylinder as an example, the processing of the first and second pins of the capacitor will be further explained:

[0036] The feeding mechanism 5 will first convey the capacitor strip to the lower cutter 2, such as Figure 4 The lower cutter 2 shown in the diagram is also machined with a limiting groove 21 for the movement of the capacitor strip. Therefore, the capacitor strip conveyed by the feeding mechanism 5 will first move into the limiting groove 21 and continue to move within the limiting groove 21 until the first lead of each capacitor is moved between the first cutter 31 and the lower cutter 2 along the moving direction. At this time, the cylinder pushes the first cutter 31 to move downward. The cutting part 312 has a flat blade. When there is relative movement between the cutting part 312 of the first cutter 31 and the blade edge of the lower cutter 2, it can generate a shearing action on the first lead, thereby cutting off the first lead from the blade edge of the lower cutter 31. Then, since the pre-bending part 311 is machined with a bevel, when the first cutter 31 continues to move downward, it will squeeze the cut first lead into the extrusion gap between the pre-bending part 311 and the block 8, causing it to undergo plastic deformation, thus completing the first lead of the capacitor. The capacitor's leads are bent, and a groove 313 for accommodating capacitor leads is machined within the first cutter 31. When the first cutter 31 presses the first lead, it can press the first lead into the groove 313. Simultaneously, the cylinder drives the upper cutter group 3 upwards, while the feeding mechanism 5 pushes the material belt forward one step until the second lead of the capacitor is moved between the second cutter 32 and the lower cutter 2. At this time, the first lead of the other capacitor moves between the first cutter 31 and the lower cutter 2. Therefore, when the cylinder drives the upper cutter group 3 downwards, the first upper cutter 31 repeats the above-mentioned cutting and bending operation on the first lead, while the second cutter 32, while moving relative to the lower cutter 2, uses shearing action to cut the second lead of the capacitor. This achieves the goal of simultaneously performing different processing operations on two leads of the capacitor using one machine, improving processing efficiency. Combined with the automatic feeding of the feeding mechanism 5, there is no need for operators to repeatedly clamp the capacitors, minimizing manual intervention and reducing the impact of manual operation on processing efficiency, thus further improving the processing efficiency of this invention.

[0037] To facilitate the collection of processed capacitors, such as Figure 1 As shown, a hopper 7 is installed in the recycling area of ​​the frame 1, and an air pipe is installed in the processing area of ​​the frame 1. The air outlet of the air pipe is directed horizontally from the cutting edge of the lower cutter 2 to the inlet of the hopper 7. During the processing, the cut and bent capacitors can be blown into the hopper 7 by sending air into the air pipe, eliminating the need for manual collection and further improving efficiency.

[0038] Furthermore, since the purchased capacitor strip is in roll form, it will naturally bend and deform after being pulled out. To prevent this bending deformation from affecting the accurate position of the capacitor leads between the upper cutter group 3 and the lower cutter 2, the first plate 51 and the second plate 52 in the feeding mechanism 5 can flatten the bent capacitor strip, allowing it to be conveyed into the limiting groove 21 of the lower cutter 2 in a straight state, which helps to ensure processing accuracy. It is evident that the feeding mechanism 5 in this invention is ingeniously designed and serves multiple purposes.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
