Description

Technical Field

[0001] This utility model relates to the field of marking device technology, and in particular to a marking device for circular arcs on iron sheets. Background Technology

[0002] Metal sheet scribing equipment is commonly used in metal processing and manufacturing to scribble lines on metal sheets or other metal plates to mark the locations and paths where cutting, drilling, or other processing is required. Through precise marking, scribing equipment helps ensure the accuracy and quality of subsequent processing. Existing metal sheet scribing equipment includes manual scribing equipment, semi-automatic scribing equipment, automatic scribing equipment, and portable scribing equipment. Semi-automatic scribing equipment uses a motor to drive a scribing needle or laser head to scribble lines along preset paths on the metal sheet. Chinese Patent Application No. 202010126413.X discloses a semi-circular iron sheet scribing device, which includes a base plate and a conveyor channel. The conveyor channel is fixedly connected to the base plate and has a square groove. A scribing mechanism is fixedly connected to the base plate near the conveyor channel. By using a motor to drive the moving frame to move left and right, the device achieves the purpose of conveying the iron sheet and can automatically place the iron sheet onto the pressure plate. The iron sheet can be processed without manual placement. During scribing, the motor drives the pen to automatically draw a semi-circle on the iron sheet, making the scribing more regular, ensuring that each shape is the same, simplifying the processing procedure, and improving production efficiency.

[0003] However, the aforementioned iron sheet marking device has a relatively simple marking function, and its adaptability is insufficient when dealing with working conditions with more complex marking shapes. Utility Model Content

[0004] Therefore, it is necessary to provide a circular arc marking device for iron sheets to address the technical problem of insufficient versatility of existing iron sheet marking devices.

[0005] A metal sheet arc marking device includes a support, a first rotating mechanism, a second rotating mechanism, and a marking mechanism. The first rotating mechanism is mounted on the top of the support, and the second rotating mechanism is located at the output end of the first rotating mechanism. Thus, the first rotating mechanism can drive the second rotating mechanism to rotate relative to the support in an arc-shaped trajectory with a preset radius. The marking mechanism is located at the output end of the second rotating mechanism, thus, the second rotating mechanism can drive the marking mechanism to rotate relative to the output end of the first rotating mechanism in an arc-shaped trajectory with a preset radius.

[0006] The first rotating mechanism includes two first sensors and two first sensing plates. According to the preset rotation range of the first rotating mechanism, the two first sensing plates are respectively set at preset positions on the side wall surface of the support and extend towards the first rotating mechanism by a preset distance; the two first sensors are set at preset positions on the side surface of the first rotating mechanism corresponding to the two first sensing plates.

[0007] The second rotating mechanism includes two second sensors and two second sensing plates. According to the preset rotation range of the second rotating mechanism, the two second sensing plates are respectively set at preset positions on the top of the second rotating mechanism and extend a preset distance toward the first rotating mechanism; the two second sensors are set on the bottom surface of the output end of the first rotating mechanism corresponding to the two first sensing plates.

[0008] In one embodiment, the first rotating mechanism further includes a first driving component and a first rotating arm. The first driving component is mounted on the top of the support. One end of the first rotating arm is connected to the output end of the first driving component, and the other end of the first rotating arm extends a preset distance toward a preset rotation range.

[0009] In one embodiment, the second rotating mechanism described above is disposed at the end of the first rotating arm.

[0010] In one embodiment, the second rotating mechanism further includes a second driving component and a second rotating arm. The second driving component is mounted on the first rotating arm. One end of the second rotating arm is connected to the output end of the second driving component, and the other end of the second rotating arm extends a preset distance toward a preset rotation range.

[0011] In one embodiment, the marking mechanism is disposed at the end of the second rotating arm, so that the marking mechanism can be driven to rotate by a preset radius during the rotation of the second rotation ratio.

[0012] In one embodiment, the first drive assembly includes a first motor, a first transmission belt, and a first connector. The first motor is mounted on one end of the support; the first connector is rotatably connected to the other end of the support; and the first transmission belt is sleeved on the output end of the first motor and the side surface of the first connector.

[0013] In one embodiment, the end face of the first connector is connected to one end of the first rotating arm.

[0014] In one embodiment, the second drive assembly includes a second motor, a second transmission belt, and a second connector. The second motor is mounted on the end of the first rotating arm; the second connector is connected to the other end of the first rotating arm; and the second transmission belt is sleeved on the output end of the second motor and the side surface of the second connector.

[0015] In one embodiment, the end face of the second connector is connected to one end of the second rotating arm.

[0016] In one embodiment, the marking mechanism includes a mounting plate, a third drive assembly, and a marking unit. One end of the mounting plate is connected to the end of the second rotating arm, and the other end of the mounting plate extends a predetermined distance toward the bottom side of the second rotating arm. The third drive assembly is mounted on one end of the mounting plate, and the marking unit is mounted on the output end of the third drive assembly.

[0017] In one embodiment, the third drive assembly includes a third motor, a third drive belt, and a third connector. The second motor is mounted on the end of the mounting plate. One end of the third drive belt is sleeved with the output end of the third motor, and the other end of the third drive belt extends along the mounting plate to the bottom end of the mounting plate. The third connector is connected to the third drive belt in a driving connection.

[0018] In one embodiment, the scribing unit described above is mounted on one side surface of the third connector.

[0019] In one embodiment, the above-mentioned marking mechanism further includes a third sensor and a third sensing plate. The third sensor is disposed at a preset position on one side of the mounting plate; the third sensing plate is disposed at a preset position on one side of the third connector, corresponding to the third sensor.

[0020] In one embodiment, the second rotating mechanism further includes a limiting post, which is disposed on the bottom surface of the first rotating arm corresponding to the second rotating arm, and the bottom end of the limiting post extends a predetermined distance toward the second rotating arm.

[0021] The aforementioned iron sheet arc scribing device, through the coordinated drive of the first and second rotating mechanisms, can expand the scribing range while flexibly planning the movement trajectory of the scribing mechanism, thereby achieving versatility in the shape of scribing lines on the iron sheet surface, flexibility, and applicability to various processing targets. A rotation area with a preset angle range is formed on one side between the two first sensing plates. When the first rotating mechanism rotates within the preset rotation range between the two first sensing plates, the two first sensors correspond to the two first sensing plates one-to-one. When a first sensor senses the corresponding first sensing plate, the first rotating mechanism stops and begins to rotate in the opposite direction until the other first sensor senses the other first sensing plate, thus limiting the rotation range of the first rotating mechanism. Simultaneously, when the second rotating mechanism rotates within the preset rotation range between the two second sensing plates, the two second sensors correspond to the second sensing plates one-to-one, thus limiting the rotation range of the second rotating mechanism. Compared with existing sheet metal marking equipment, the sheet metal arc marking device of this invention can effectively control the marking range of the marking mechanism by limiting the rotation range of the first and second rotating mechanisms. At the same time, it facilitates the controller to monitor and control the motion trajectory of the marking mechanism, thereby improving the marking accuracy and efficiency, and thus improving the yield and production efficiency of sheet metal arc marking processing.

[0030] Please see Figures 1 to 2This utility model discloses a circular arc scribing device for iron sheets. The device includes a support 100, a first rotating mechanism 200, a second rotating mechanism 300, and a scribing mechanism 400. The first rotating mechanism 200 is mounted on the top of the support 100, and the second rotating mechanism 300 is disposed at the output end of the first rotating mechanism 200. Thus, the first rotating mechanism 200 can drive the second rotating mechanism 300 to rotate relative to the support 100 along a circular arc trajectory with a preset radius. The scribing mechanism 400 is disposed at the output end of the second rotating mechanism 300, thus, the second rotating mechanism 300 can drive the scribing mechanism 400 to rotate relative to the output end of the first rotating mechanism 200 along a circular arc trajectory with a preset radius. Based on this, the scribing mechanism 400, through the coordinated drive of the first rotating mechanism 200 and the second rotating mechanism 300, can expand the scribing range while flexibly planning the movement trajectory of the scribing mechanism 400, thereby achieving versatility in the shape and flexibility of scribing lines on the iron sheet surface, as well as its applicability to various processing targets. Specifically, the first rotating mechanism 200 includes two first sensors 210 and two first sensing plates 220. According to the preset rotation range of the first rotating mechanism 200, the two first sensing plates 220 are respectively disposed at preset positions on the side wall surface of the support 100 and extend towards the first rotating mechanism 200 by a preset distance. A rotation area with a preset angle range is formed on one side between the two first sensing plates 220. The two first sensors 210 are disposed at preset positions on the side surface of the first rotating mechanism 200 corresponding to the two first sensing plates 220. When the first rotating mechanism 200 rotates within the preset rotation range between the two first sensing plates 220, the two first sensors 210 respectively cooperate with the two first sensing plates 220 in a one-to-one correspondence. When a first sensor 210 senses the corresponding first sensing plate 220, the first rotating mechanism 200 stops and begins to rotate in the opposite direction. The rotation continues until another first sensor 210 senses another first sensing plate 220, thus limiting the rotation range of the first rotating mechanism 200. Simultaneously, the second rotating mechanism 300 includes two second sensors 310 and two second sensing plates 320. According to the preset rotation range of the second rotating mechanism 300, the two second sensing plates 320 are respectively positioned at preset points on the top of the second rotating mechanism 300 and extend a preset distance toward the first rotating mechanism 200. The two second sensors 310 are positioned on the bottom surface of the output end of the first rotating mechanism 200, corresponding to the two first sensing plates 220. When the second rotating mechanism 300 rotates within the preset rotation range between the two second sensing plates 320, the two second sensors 310 cooperate with the second sensing plates 320 one-to-one, thereby limiting the rotation range of the second rotating mechanism 300.Compared with existing sheet metal marking equipment, the sheet metal arc marking device of this invention can effectively control the marking range of the marking mechanism 400 by limiting the rotation range of the first rotating mechanism 200 and the second rotating mechanism 300. At the same time, it facilitates the controller to monitor and control the movement trajectory of the marking mechanism 400, thereby improving the marking accuracy and efficiency, and thus improving the yield and production efficiency of sheet metal arc marking processing.

[0031] Furthermore, the first rotating mechanism 200 also includes a first driving assembly 230 and a first rotating arm 240. The first driving assembly 230 is mounted on the top of the support 100. One end of the first rotating arm 240 is connected to the output end of the first driving assembly 230, and the other end of the first rotating arm 240 extends a preset distance toward a preset rotation range, thereby forming a driving mechanism with a rotation driving function within a preset range. Specifically, a second rotating mechanism 300 is disposed at the end of the first rotating arm 240, so that the first rotating arm 240 can drive the second rotating mechanism 300 to rotate with a preset radius during rotation.

[0032] Furthermore, the second rotating mechanism 300 also includes a second driving assembly 330 and a second rotating arm 340. The second driving assembly 330 is mounted on the first rotating arm 240. One end of the second rotating arm 340 is connected to the output end of the second driving assembly 330, and the other end of the second rotating arm 340 extends a preset distance toward a preset rotation range, thereby forming a driving mechanism with a rotation driving function within a preset range. Specifically, the scribing mechanism 400 is disposed at the end of the second rotating arm 340, so that the second rotation ratio can drive the scribing mechanism 400 to rotate with a preset radius during rotation.

[0033] Furthermore, the first drive assembly 230 includes a first motor 231, a first transmission belt 232, and a first connector 233. The first motor 231 is mounted on one end of the support 100; the first connector 233 is rotatably connected to the other end of the support 100; the first transmission belt 232 is sleeved on the output end of the first motor 231 and the side surface of the first connector 233, thereby realizing the drive connection between the output end of the first motor 231 and the first connector 233. Specifically, the end face of the first connector 233 is connected to one end of the first rotating arm 240, so that the first motor 231 sequentially drives the first rotating arm 240 to rotate at a preset speed through the first transmission belt 232 and the first connector 233.

[0034] Furthermore, the second drive assembly 330 includes a second motor 331, a second transmission belt 332, and a second connector 333. The second motor 331 is mounted on the end of the first rotating arm 240; the second connector 333 is connected to the other end of the first rotating arm 240; the second transmission belt 332 is sleeved on the output end of the second motor 331 and the side surface of the second connector 333, thereby realizing the drive connection between the output end of the second motor 331 and the second connector 333. Specifically, the end face of the second connector 333 is connected to one end of the second rotating arm 340, so that the second motor 331 sequentially drives the second rotating arm 340 to rotate at a preset speed through the second transmission belt 332 and the second connector 333.

[0035] Furthermore, the marking mechanism 400 includes a mounting plate 410, a third drive assembly 420, and a marking unit 430. One end of the mounting plate 410 is connected to the end of the second rotating arm 340, and the other end of the mounting plate 410 extends a predetermined distance toward the bottom side of the second rotating arm 340. The third drive assembly 420 is mounted on one end of the mounting plate 410. The marking unit 430 is mounted on the output end of the third drive assembly 420, so that the third drive assembly 420 can drive the marking unit 430 to move up and down relative to the mounting plate 410.

[0036] Furthermore, the third drive assembly 420 includes a third motor 421, a third transmission belt 422, and a third connector 423. The second motor 331 is mounted on the end of the mounting plate 410. One end of the third transmission belt 422 is sleeved with the output end of the third motor 421, and the other end of the third transmission belt 422 extends along the mounting plate 410 to the bottom end of the mounting plate 410, thereby forming a transmission mechanism. The third connector 423 is connected to the third transmission belt 422, thereby enabling the third connector 423 to move up and down along the third transmission belt 422. Specifically, the marking unit 430 is mounted on one side surface of the third connector 423, so that the third motor 421 can drive the third connector 423 to move up and down along the mounting plate 410 by a preset distance via the third transmission belt 422.

[0037] Furthermore, the marking mechanism 400 also includes a third sensor 440 and a third sensing plate 450. The third sensor 440 is disposed at a preset position on one side of the mounting plate 410; the third sensing plate 450 is disposed at a preset position on one side of the third connector 423 corresponding to the third sensor 440. During the lifting and lowering process of the third connector 423, the controller can monitor and control the lifting and lowering state of the marking unit 430 through the cooperation state between the third sensor 440 and the third sensing plate 450.

[0038] Furthermore, the second rotating mechanism 300 also includes a limiting post 350, which is disposed on the bottom surface of the first rotating arm 240 corresponding to the second rotating arm 340. The bottom end of the limiting post 350 extends a preset distance toward the second rotating arm 340, so that when the second rotating arm 340 rotates relative to the first rotating arm 240 to a preset position, the corresponding side surface of the second rotating arm 340 can abut against the limiting post 350. This realizes the limiting function of the limiting post 350 on the second rotating arm 340, thereby avoiding excessive rotation of the second rotating arm 340 and affecting the normal cooperation between the second sensor 310 and the second sensing plate 320, and ensuring the effectiveness of the controller's monitoring and control of the second rotating arm 340.

[0039] In summary, the iron sheet arc scribing device disclosed in this utility model, through the coordinated drive of the first and second rotating mechanisms, can expand the scribing range while flexibly planning the movement trajectory of the scribing mechanism, thereby achieving versatility in the shape of scribing lines on the iron sheet surface, flexibility, and applicability to various processing targets. A rotation area with a preset angle range is formed on one side between the two first sensing plates. When the first rotating mechanism rotates within the preset rotation range between the two first sensing plates, the two first sensors respectively cooperate with the two first sensing plates. When the first sensor senses the corresponding first sensing plate, the first rotating mechanism stops and begins to rotate in the opposite direction until the other first sensor senses the other first sensing plate, thus limiting the rotation range of the first rotating mechanism. At the same time, when the second rotating mechanism rotates within the preset rotation range between the two second sensing plates, the two second sensors respectively cooperate with the second sensing plates, thus limiting the rotation range of the second rotating mechanism. Compared with existing sheet metal marking equipment, the sheet metal arc marking device of this invention can effectively control the marking range of the marking mechanism by limiting the rotation range of the first and second rotating mechanisms. At the same time, it facilitates the controller to monitor and control the motion trajectory of the marking mechanism, thereby improving the marking accuracy and efficiency, and thus improving the yield and production efficiency of sheet metal arc marking processing.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
