Cutting apparatus for capacitor production

Abstract

This utility model discloses a cutting device for capacitor production, including a cutting machine body. A PLC controller is embedded in the outer wall of the cutting machine body, and a servo motor is installed inside one end of the cutting machine body. In use, as the strip capacitor product is continuously conveyed by a rotating feeding roller, whenever the lead at one end of the strip capacitor product passes an infrared ranging sensor parallel to the cutting blade, the sensor is blocked, affecting its measured distance. The monitored data is then fed back to the PLC controller, which controls the telescopic cylinder to start, causing the cutting blade to extend upwards, thus cutting the lead at one end of the strip capacitor product. The cut lead falls into the collection drawer under gravity and is collected. Compared to ordinary mechanical reciprocating cutting structures, this reduces the problem of missed lead cutting on strip capacitor products and improves the cutting quality.

Description

Technical Field

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

[0002] Capacitors are components used to store electrical charge in electronic circuits and are widely used in the electronics industry. Capacitor cutting machines are commonly used in the production and processing of capacitors. The main function of capacitor cutting machines is to cut off the leads of capacitors, thereby improving the production efficiency and quality of capacitor products.

[0003] Current capacitor manufacturing cutting equipment often relies on the reciprocating motion of a cutting blade to continuously cut the leads of the conveyed strip capacitor products. This process is prone to issues such as the cutting blade missing its target and leads not being cut, resulting in poor cutting quality. Furthermore, these devices are also prone to problems such as insufficient conveying tension and product entanglement during continuous conveying of strip capacitor products, which affects the smoothness of the conveying process. Based on these issues, we propose a new type of capacitor manufacturing cutting equipment. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for capacitor production, in order to solve the problems mentioned in the background art, such as poor cutting accuracy, easy omission of pins, inability to adjust transmission tension, and poor smoothness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for capacitor production, comprising a cutting machine body, a PLC controller embedded in the outer wall of the cutting machine body, a servo motor installed inside one end of the cutting machine body, a rotary feeding roller connected to the output end of the servo motor, a conductive rubber pressure sensor fixed to the outer wall of the rotary feeding roller, a first positioning seat fixed to one end of the rotary feeding roller, a first adjusting sleeve fitted to the other end of the rotary feeding roller, and a first electric telescopic rod evenly installed between the first adjusting sleeve and the cutting machine body. Insertion screws are evenly inserted into the cutting machine body below the transfer feed roller. An infrared ranging sensor and a telescopic cylinder are fixed between adjacent insertion screws in sequence. A cutting blade is installed at the output end of the telescopic cylinder. A second electric telescopic rod is evenly fixed at the top of the cutting machine body. A tension adjusting roller is connected to the output end of the second electric telescopic rod. A limit guide roller is fixed on the cutting machine body above the tension adjusting roller. A second positioning seat is fixed at one end of both the tension adjusting roller and the limit guide roller. A second adjusting sleeve is slidably fitted at the other end of both the tension adjusting roller and the limit guide roller.

[0006] As a further technical solution of this utility model, rubber buffer feet are evenly fitted at the bottom of the cutting machine body.

[0007] As a further technical solution of this utility model, two electric telescopic rods are provided, and the first electric telescopic rods are respectively arranged on both sides of the rotating feeding roller.

[0008] As a further technical solution of this utility model, a material collection drawer is slidably connected inside the cutting machine body below the cutting blade, and a sponge buffer layer is provided on the inner side wall of the material collection drawer.

[0009] As a further technical solution of this utility model, the plug-in screw extends laterally through one end of the cutting machine body, and a fixing nut is evenly threaded onto the plug-in screw.

[0010] As a further technical solution of this utility model, the outer walls of the tension adjusting roller, the limiting guide roller and the rotating feeding roller are all provided with scale lines.

[0011] As a further technical solution of this utility model, a reserved slider is provided at the end of the tension adjusting roller away from the second electric telescopic rod, and a reserved slide groove is provided on the cutting machine body that is slidably connected to the reserved slider.

[0012] As a further technical solution of this utility model, both sides of the tension adjusting roller and the limiting guide roller are provided with adjusting cavities that are slidably connected to the second adjusting sleeve, and both the tension adjusting roller and the limiting guide roller are threadedly connected with locking screws that press against the adjusting cavities.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By installing tension adjusting rollers, the device optimizes its structure. Firstly, the user can slide the second adjusting sleeve fitted at one end of the tension adjusting roller and the limiting guide roller according to the width of the strip capacitor product to be cut. This ensures the distance between the second adjusting sleeve and the second positioning seat at both ends of the tension adjusting roller and the limiting guide roller equals the product width. Furthermore, the user needs to activate the first electric telescopic rod to change the horizontal position of the first adjusting sleeve fitted at one end of the rotating feed roller, ensuring the distance between the first adjusting sleeve and the first positioning seat at both ends of the rotating feed roller equals the product width. This facilitates positioning and limiting the edge of the strip capacitor product, making it easier to determine the cutting position and preventing product offset during transport, which could lead to incorrect cutting points and improve cutting accuracy. Secondly, the user can utilize the through-type insertion between the insertion screw and the cutting machine body to adjust the insertion screw... The cutting blade mounted on the rod is positioned so that it faces the pins of the strip capacitor product being fed onto the rotating feed roller. A fixing nut then locks the insertion screw and the cutting machine body in place. As the strip capacitor product is continuously fed out by the rotating feed roller, whenever the pins of the strip capacitor product pass an infrared distance sensor positioned parallel to the cutting blade, the sensor is blocked, affecting the distance it measures. The monitored data is then fed back to the PLC controller, which controls the telescopic cylinder to start, causing the cutting blade to extend upwards and cut the pins of the strip capacitor product. The cut pins then fall into the collection drawer under gravity and are collected. Compared to ordinary mechanical reciprocating cutting structures, this reduces the problem of missing pins on the strip capacitor product and improves the cutting quality.

[0015] By incorporating conductive rubber pressure sensors, the device optimizes its performance. Firstly, the conductive rubber pressure sensors wound on the rotating feed roller comprehensively monitor the pressure data of the passing strip capacitor products. This pressure represents the transmission tension of the strip capacitor products as they pass sequentially through the limit guide roller, tension adjusting roller, and rotating feed roller. The measured tension data is fed back to the PLC controller, enabling intelligent control of the second electric telescopic rod to activate, driving the tension adjusting roller to rise and fall, thus changing its operating height. The tension adjusting roller supports the rising or falling of the conveying strip capacitor products, altering the transmission tension. This helps solve the problem of wrinkles caused by uneven tension, improving the smoothness and stability of the conveying process. Secondly, the servo motor activates, driving the rotating feed roller to continuously convey the strip capacitor products, facilitating continuous cutting processing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 An embodiment of this utility model is provided: a cutting device for capacitor production, including a cutting machine body 1, a PLC controller 13 embedded in the outer wall of the cutting machine body 1, a servo motor 2 installed inside one end of the cutting machine body 1, a rotating feeding roller 10 connected to the output end of the servo motor 2, and a conductive rubber pressure sensor 23 fixed on the outer wall of the rotating feeding roller 10.

[0024] One end of the rotating feeding roller 10 is fixed with a first positioning seat 4, and the other end of the rotating feeding roller 10 is fitted with a first adjusting sleeve 8. A first electric telescopic rod 9 is evenly installed between the first adjusting sleeve 8 and the cutting machine body 1.

[0025] Insertion screws 20 are evenly inserted into the cutting machine body 1 below the rotating feeding roller 10. Infrared ranging sensors 21 and telescopic cylinders 22 are fixed between adjacent insertion screws 20 in sequence. A cutting blade 11 is installed at the output end of the telescopic cylinder 22.

[0026] A material collection drawer 12 is slidably connected inside the cutting machine body 1 below the cutting blade 11, and a sponge buffer layer is provided on the inner side wall of the material collection drawer 12.

[0027] The insertion screw 20 extends laterally through one end of the cutting machine body 1, and a fixing nut 19 is evenly threaded onto the insertion screw 20;

[0028] The outer walls of the tension adjusting roller 5, the limiting guide roller 6, and the rotating feed roller 10 are all provided with scale lines;

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the user can utilize the through-connection between the insertion screw 20 and the cutting machine body 1 to adjust the position of the cutting blade 11 mounted on the insertion screw 20, ensuring it faces the pins of the strip capacitor product being fed onto the rotating feed roller 10. Then, the fixing nut 19 is used to lock the insertion screw 20 and the cutting machine body 1. Subsequently, as the strip capacitor product is continuously fed through the rotating feed roller 10, each time the pins of the strip capacitor product pass the infrared ranging sensor positioned parallel to the cutting blade 11... 21 will block the infrared ranging sensor 21, affecting the distance it measures, and then feed the monitored data back to the PLC controller 13, so that the PLC controller 13 can control the telescopic cylinder 22 to start, driving the cutting blade 11 to extend upward, so as to cut the pins at one end of the strip capacitor product. The cut pins will fall into the collection drawer 12 under the action of gravity and be collected. Compared with the ordinary mechanical reciprocating cutting structure, it reduces the problem of missing pins on the strip capacitor product and improves the cutting processing quality.

[0030] The top of the cutting machine body 1 is uniformly fixed with a second electric telescopic rod 3. The output end of the second electric telescopic rod 3 is connected to a tension adjusting roller 5. A limit guide roller 6 is fixed on the cutting machine body 1 above the tension adjusting roller 5. A second positioning seat 18 is fixed at one end of both the tension adjusting roller 5 and the limit guide roller 6. A second adjusting sleeve 16 is slidably fitted at the other end of both the tension adjusting roller 5 and the limit guide roller 6.

[0031] Rubber buffer feet are evenly fitted at the bottom of the cutting machine body 1;

[0032] Two first electric telescopic rods 9 are provided, and the first electric telescopic rods 9 are respectively arranged on both sides of the rotating feeding roller 10;

[0033] A reserved slider 14 is provided at the end of the tension adjusting roller 5 away from the second electric telescopic rod 3, and a reserved slide groove 7 is provided on the cutting machine body 1 that is slidably connected to the reserved slider 14.

[0034] Both sides of the tension adjusting roller 5 and the limiting guide roller 6 are provided with adjusting cavities 15 that are slidably connected to the second adjusting sleeve 16. Both the tension adjusting roller 5 and the limiting guide roller 6 are threadedly connected with locking screws 17 that press against the adjusting cavities 15.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the conductive rubber pressure sensor 23 wound on the rotating feed roller 10 can comprehensively monitor the pressure data of the passing strip capacitor product. This pressure is the transmission tension of the strip capacitor product as it passes through the limit guide roller 6, tension adjusting roller 5, and rotating feed roller 10 in sequence. The measured tension data is fed back to the PLC controller 13, which enables the PLC controller 13 to intelligently control the second electric telescopic rod 3 to start, driving the tension adjusting roller 5 to move up and down, changing the working height of the tension adjusting roller 5. By raising or lowering the tension adjusting roller 5 to support the strip capacitor product during transmission, the transmission tension of the product is changed. This helps to solve the problem of wrinkles caused by uneven tension in the product and improves the smoothness and stability of transmission.

[0036] Working Principle: When in use, with an external power supply, the user first adjusts the tension adjusting roller 5 and the second adjusting sleeve 16 fitted at one end of the limiting guide roller 6 according to the width of the strip capacitor product to be cut. This ensures that the distance between the second adjusting sleeve 16 and the second positioning seat 18 at both ends of the tension adjusting roller 5 and the limiting guide roller 6 is equal to the product width. Furthermore, the user needs to activate the first electric telescopic rod 9 to change the horizontal position of the first adjusting sleeve 8 fitted at one end of the rotating feed roller 10. This ensures that the distance between the first adjusting sleeve 8 and the first positioning seat 4 at both ends of the rotating feed roller 10 is equal to the product width, facilitating the positioning and limiting of the strip capacitor product's edge. This helps determine the cutting position and avoids transmission errors. The problem of product misalignment during the process leading to incorrect cutting points of the cutting blade 11 is addressed by improving cutting accuracy. Simultaneously, the user can utilize the through-connection between the insertion screw 20 and the cutting machine body 1 to adjust the position of the cutting blade 11 mounted on the insertion screw 20, ensuring it is aligned with the pins of the strip capacitor product fed onto the rotating feed roller 10. The fixing nut 19 then secures the insertion screw 20 and the cutting machine body 1. Subsequently, the servo motor 2 starts, driving the rotating feed roller 10 to rotate, continuously conveying the strip capacitor product, facilitating continuous cutting processing. Furthermore, the strip capacitor product is continuously fed through the rotating feed roller 10... When the strip capacitor product is conveyed, whenever one end of the lead passes the infrared distance sensor 21, which is set parallel to the cutting blade 11, the infrared distance sensor 21 is blocked, affecting the distance it measures. The monitored data is then fed back to the PLC controller 13, which controls the telescopic cylinder 22 to start, causing the cutting blade 11 to extend upwards and cut the lead at one end of the strip capacitor product. The cut lead then falls into the collection drawer 12 under gravity and is collected. Compared with the ordinary mechanical reciprocating cutting structure, this reduces the problem of missing leads on the strip capacitor product and improves the cutting quality. In addition, the rotating feeding roller 10... The conductive rubber pressure sensor 23, which is wound on the upper part, can comprehensively monitor the pressure data of the passing strip capacitor product. This pressure is the transmission tension of the strip capacitor product as it passes through the limit guide roller 6, tension adjusting roller 5, and rotating feed roller 10 in sequence. The measured tension data is fed back to the PLC controller 13, which can intelligently control the second electric telescopic rod 3 to start, drive the tension adjusting roller 5 to move up and down, change the working height of the tension adjusting roller 5, and support the strip capacitor product in the transmission by raising or lowering it, thereby changing the transmission tension of the product. This helps to solve the wrinkling problem caused by uneven tension of the product and improves the smoothness and stability of the transmission.
