Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to an automatic cutting device. Background Technology

[0002] Springs are key components with specific elastic functions and precision structures. Their core functions include, but are not limited to, conductive connections within electronic devices, buffering and resetting in mechanical structures, or gap compensation and contact conduction in precision instruments. Due to the need to adapt to the functional requirements of different assembly scenarios, springs typically feature a thin, lightweight, high-precision structure with a specific elastic coefficient.

[0003] The spring is processed as a continuous strip and then cut into shape using a cutting device. However, in the existing technology, when the strip is cut, the finished spring is mixed with the strip. The spring and waste need to be separated manually. On the one hand, the friction between the waste and the spring causes wear on the surface of the spring. On the other hand, since the spring and waste are small in size, a lot of time is required to separate them, which reduces production efficiency and increases production costs. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic cutting device that can solve the above-mentioned technical problems;

[0005] This utility model provides an automatic cutting device, including a housing, and further comprising:

[0008] The conveyor mechanism used to transfer the finished products cut by the cutting mechanism is set on the box and placed below the conveyor track;

[0009] A recycling mechanism for collecting waste material cut by the cutting mechanism is installed on the box and adjacent to the output end of the conveyor.

[0035] The technical solution of this utility model uses a cutting mechanism to accurately position and cut the material belt conveyed by the conveyor, ensuring that the processing accuracy of the spring sheet meets the assembly requirements. After cutting, the finished spring sheet is directly conveyed by a dedicated conveying mechanism, while the waste material is simultaneously recycled by a recycling mechanism, realizing the immediate separation of finished product and waste material after cutting, completely avoiding frictional contact during manual separation.

Detailed Implementation

[0049] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] like Figure 1-9 As shown, this utility model proposes an automatic cutting device, including a housing 100, and universal wheels are provided at the bottom of the housing 100. The housing 100 can be pushed as needed, and its position can be changed with the support of the universal wheels; it also includes:

[0053] A feeding mechanism 200 is located on one side of the housing 100 and adjacent to the feeding end of the conveyor 300 located on the housing 100. A material strip is wound around the feeding mechanism 200 and conveyed into the conveyor 300. A cutting mechanism 400 is located on the housing 100 and on one side of the conveyor 300. The cutting mechanism 400 positions and cuts the material strip conveyed from the conveyor 300. A conveying mechanism 500 is located on the housing 100 and below the conveyor 300. The conveying mechanism 500 conveys the finished product cut by the cutting mechanism 400. A recycling mechanism 600 is located on the housing 100 and adjacent to the output end of the conveyor 300. The recycling mechanism 600 recycles the waste material cut by the cutting mechanism 400.

[0054] Specifically, after the material strip is conveyed to the cutting mechanism 400 by the conveyor 300, the material strip is cut by the cutting mechanism 400. The cut finished spring pieces fall onto the conveying mechanism 500 after passing through the cutting mechanism 400, and are conveyed to the designated position by the conveying mechanism 500. The waste material (the remaining part of the material strip after the spring pieces are cut off) is further conveyed by the conveyor 300 and enters the recycling mechanism 600, where the waste material is recycled. The recycling mechanism 600 is a recycling cylinder, and the recycling cylinder is provided with a bending part to change the conveying direction of the waste material and avoid waste accumulation. In this way, after the waste material enters the recycling cylinder, its conveying direction is changed by the action of the recycling cylinder, and then it passes through the recycling cylinder and reaches the recycling position.

[0055] The technical solution of this utility model uses a cutting mechanism 400 to precisely position and cut the material strip conveyed by the conveyor 300, ensuring that the processing accuracy of the spring sheet meets the assembly requirements. After cutting, the finished spring sheet is directly conveyed by a dedicated conveying mechanism 500, while the waste material is simultaneously recycled by a recycling mechanism 600, realizing the immediate separation of finished product and waste material after cutting, completely avoiding frictional contact during manual separation. The entire process is free from manual intervention in the contact of the spring sheet, effectively protecting the integrity of the spring sheet surface and the structural accuracy, avoiding the failure of the elastic coefficient or abnormality of conductivity and buffering function due to wear, and ensuring product qualification.

[0056] In addition, the feeding mechanism 200 and the conveyor 300 are precisely connected to ensure that the material belt is stably transported to the cutting mechanism 400, avoiding cutting errors caused by feeding deviations. The cutting, conveying, and recycling mechanisms 600 are all integrated into the housing 100, with seamless connection between each link and no interruption points due to manual intervention. This adapts to the processing rhythm of continuous material belts and ensures the stability and consistency of the production process. The fully automated operation reduces the risk of human error and further improves the controllability of the production process, providing stable equipment support for the mass production of spring sheets.

[0057] like Figure 1 and Figure 7 As shown, this utility model also includes a detection mechanism 700; the detection mechanism 700 is disposed on the conveyor 300 and positioned above the conveyor 300, and detects whether there is a material belt being conveyed on the conveyor 300; if there is no material belt on the conveyor 300, a signal is generated to stop the overall operation; preferably, the detection mechanism 700 is a photoelectric sensor.

[0058] like Figure 1 As shown, a protective cover 800 is also provided on the housing 100. The protective cover 800 houses the conveyor 300, cutting mechanism 400, and conveying mechanism 500, thereby preventing the operator from accidentally contacting these components and causing injury to the user during use. Specifically, a protective frame is provided on the housing 100, and the protective cover 800 is mounted on the protective frame; the feeding mechanism 200 passes through the protective cover 800, thereby enabling better installation and replacement of the material belt.

[0059] like Figure 2 , Figure 5 and Figure 6As shown, the feeding mechanism 200 includes a feeding rack 201, a first driving device 202, and a feeding channel 204. The feeding rack 201 is mounted on the housing 100. The first driving device 202 is mounted on the feeding rack 201, and a material wheel 203 is mounted on the first driving device 202. The feeding channel 204 is mounted on the feeding rack 201, and one end is adjacent to the feeding end of the conveyor 300. The material belt is wound around the material wheel 203, and under the drive of the first driving device 202, the material belt enters the feeding channel 204, and after continuous conveying in the feeding channel 204, it enters the conveyor 300. Preferably, the first driving device 202 is a motor. The protective cover 800 has an opening corresponding to the position of the feeding channel 204 of the feeding mechanism 200. The opening size is 5-10 mm larger than the width of the feeding channel 204 to ensure that the material belt passes through smoothly without any risk of exposure.

[0060] Of course, to better facilitate the movement of the material belt within the feed channel 204 and the conveyor 300, a feeding mechanism 205 is preferably provided. The feeding mechanism 205 is mounted on the housing 100. The feeding mechanism 205 pushes the material belt to move within the feed channel 204 and the conveyor 300, thereby improving the efficiency of the material belt movement. The feeding mechanism 205 includes a second drive device 251, a transmission block 252, and a deflecting block 253. The second drive device 251 is mounted on the housing 100. The transmission block 252 is located at the output end of the second drive device 251. The deflecting block 253 is mounted on the transmission block 252. During use, the second drive device 251 drives the transmission block 252 to perform linear reciprocating motion, and the transmission block 252 drives the deflecting block 253 to move simultaneously, thereby enabling the material belt to move within the conveyor 300 by the deflecting block 253.

[0061] like Figure 4 and Figure 7 As shown, the actuating block 253 includes a connecting block and an actuating block. The connecting block is mounted on the conveying block, and the actuating block is pinned to the connecting block. The actuating block has a vertical surface and an inclined surface on both sides. The vertical surface is the forward direction of the actuating block (the conveying direction of the material belt). When the second driving device 251 is activated, the end of the actuating block (the part that contacts the positioning hole on the material belt) is inserted into the positioning hole and pushes the material belt to move within the conveyor 300 through the vertical surface. When the second driving device 251 moves in the reverse direction, the forward force applied to the actuating block disappears. By driving the actuating block to move in the reverse direction, due to the presence of the inclined surface, the actuating block separates from the positioning hole and moves simultaneously with the second actuating device. Under the reciprocating motion of the second driving device 251, the actuating block is inserted into different positioning holes, thereby continuously pushing the material belt to move within the conveyor 300. Preferably, the second driving device 251 is a cylinder.

[0062] like Figure 5-9As shown, the cutting mechanism 400 includes a cutting frame 401, a third driving device 402, a lower module 403, and an upper module 404; the cutting frame 401 is mounted on the housing 100; the third driving device 402 is mounted on the cutting frame 401; the lower module 403 is mounted on a mounting bracket on the housing 100, and the conveyor 300 passes through the lower module 403; the upper module 404 is mounted on the third driving device 402, and a cutting block 405 is mounted on the upper module 404; wherein, the lower module 403 is fixed to the cutting table on the housing 100, the third driving device 402, the lower module 403, the third driving device 402, the lower module 403, the third driving device 402, the lower module 403, the third driving device 402, the lower module 403, the third driving device 402, the lower module 403, the third driving device 404, the lower module 403, the third driving device 404, the lower module 403, the third driving device 404, the lower module 404, the third driving device 402 ... lower module 405, the lower module 406, the lower module 407, the lower module 408, the lower module 409, the lower module 400, the lower module 400, the lower module 400, the lower module 401, the lower module 402, the lower module 400, the lower module 401, the lower module 402, the lower module 400, the lower module 401, the lower module 40 The third drive device 402 operates on the cutting frame 401, driving the upper module 404 to contact the lower module 403. After the upper module 404 and the lower module 403 contact, the cutting block 405 cuts the material strip on the conveyor 300. The cut finished spring sheet passes through the lower module 403 and falls into the conveying mechanism 500, where it is conveyed. The cut waste material continues to be conveyed on the conveyor 300 and enters the recycling mechanism 600. In this utility model, the third drive device 402 is an electric punch press.

[0063] The upper module 404 includes a fixed mold 441 and a moving mold 443. The fixed mold 441 is connected to the lower module 403 via several guide rods 442. The moving mold 443 passes through the guide rods 442 and is connected to the fixed mold 441 via several positioning rods. The fixed mold 441 is connected to the output end of the third drive device 402. A cutting block 405 is disposed on the moving mold 443 and passes through the fixed mold 441. The third drive device 402 simultaneously drives the fixed mold 441 and the moving mold 443 to move, and after the fixed mold 441 contacts the lower module 403, it continues to move. The moving mold 443 continues to operate, and the cutting block 405 on the moving mold 443 cuts the material strip on the conveyor 300. After cutting, the finished spring sheet passes through the lower mold 403 and is placed on the conveyor mechanism 500. The third drive device 402 drives the fixed mold 441 and the moving mold 443 to reset, and the control mechanism 900 triggers the feeding mechanism 205 to move. The toggle block 253 pushes the material strip to move a preset distance to ensure that the next cutting station is accurately aligned with the cutting block 405. The reciprocating motion realizes the cutting of the material strip on the conveyor 300 one by one.

[0064] In addition, to ensure the accuracy of the cutting position when cutting the strip, it is preferable to provide a number of positioning pins 444 on the fixed mold 441. The positioning pins 444 are used to position the strip before cutting. Specifically, before the fixed mold 441 contacts the lower mold assembly 403, the positioning pins 444 are inserted into the positioning holes on the strip. After the fixed mold 441 contacts the lower mold assembly 403, the fixed mold 441 and the positioning pins 444 cooperate to perform double positioning of the strip to ensure the accuracy of the cutting position.

[0065] like Figure 5 and 6As shown, the conveying mechanism 500 includes a fourth drive device 501 and a conveyor belt 502. The fourth drive device 501 is mounted on the housing 100; the conveyor belt 502 is mounted on the housing 100 and connected to the fourth drive device 501; the conveyor belt 502 is driven by the fourth drive device 501 to move, and when the cut finished product falls into the conveyor belt 502, the finished product spring is conveyed by the conveyor belt 502; preferably, the fourth drive device 501 is a motor.

[0066] It should be noted that a control mechanism 900 is also provided in this utility model. The control mechanism 900 sets parameters and controls the operation of the feeding mechanism 200, the cutting mechanism 400, and the conveying mechanism 500. The control mechanism 900 is electrically connected to the first drive device 202 of the feeding mechanism 200, the second drive device 251 of the feeding mechanism 205, the third drive device 402 of the cutting mechanism 400, the fourth drive device 501 of the conveying mechanism 500, and the detection mechanism 700. When the detection mechanism 700 detects that there is no material belt in the conveyor 300, it sends a signal to the control mechanism 900, and the control mechanism 900 triggers all drive devices to stop. In addition, the control mechanism 900 synchronously regulates the rotation speed of the first drive device 202 and the reciprocating frequency of the second drive device 251 to ensure that the feeding speed of the material wheel 203 is consistent with the pushing rhythm of the pusher block 253. The control mechanism 900 is a controller in the prior art, which will not be further described in this utility model.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
