[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] This application provides an auxiliary processing device for laser marking, which can solve the problem in related technologies where the angle cannot be adjusted when marking images, text, numbers or lines on a workpiece at an angle, thus failing to meet the user's needs.

[0030] See Figures 1 to 7 This application provides an auxiliary processing device for laser marking, comprising: a base 1, a first fixing device 2, and a second fixing device 3. The base 1 has a mounting groove 12 with scale markings. The first fixing device 2 includes a rotating assembly 22, which includes a clamping plate 222 and a turntable 221 with scale markings. The clamping plate 222 is coaxially arranged with the turntable 221 and rotates relative to the turntable 221. The second fixing device 3 is installed in the mounting groove 12 and rotates relative to the mounting groove 12.

[0031] In this application, the first fixing device 2 can clamp a hard workpiece with a clamping plate 222. When it is necessary to mark images, text, numbers or lines on different surfaces of the workpiece, the clamping plate 222 drives the workpiece to rotate relative to the turntable 221. Since the turntable 221 is provided with scale marks, the rotation angle of the workpiece can be accurately adjusted. The second fixing device 3 is placed with a soft material such as cloth or plastic. When it is necessary to mark images, text, numbers or lines at an angle on the soft workpiece, the second fixing device 3 drives the workpiece to rotate relative to the mounting groove 12. Since the mounting groove 12 is provided with scale marks, the rotation angle of the workpiece can be accurately adjusted.

[0032] In some embodiments, the first fixing device 2 includes a second moving component 21 and a first moving component 20. The second moving component 21 is vertically disposed on the base 1 and is connected to the rotating component 22; the first moving component 20 is horizontally disposed on the base 1 and is connected to the second moving component 21. The first moving component 20 is disposed at the bottom of the base 1, and there are two second moving components 21, each disposed at the top of the base 1. When the first moving component 20 is working, it can drive the second moving component 21 along the length direction of the base 1. Figure 1 The base 1 moves in the X direction, at which time the relative distance between the two second moving components 21 increases or decreases; each second moving component 21 is connected to a rotating component 22, and when the second moving component 21 is working, it can drive the rotating component 22 along the height direction of the base 1 (in the X direction). Figure 1 The first moving component 20 moves up and down in the Y direction. Therefore, the second moving component 21 works in conjunction with the first moving component 20. When marking is required on a hard workpiece, the first moving component 20 can adjust the relative distance between the two rotating components 22 so that the two rotating components 22 can work together to clamp or release the hard workpiece. The second moving component 21 can adjust the height of the two rotating components 22.

[0033] A marking machine 10 is installed on the base 1. The marking machine 10 can mark hard workpieces held by the clamping plate 222 and soft workpieces placed on the second fixing device 3. The marking machine 10 can drive the marking head to move up and down, left and right and back and forth.

[0034] There are several ways to configure the first moving component 20:

[0035] In some possible embodiments, a groove 11 is provided at the top of the base 1; the first moving component 20 includes a first motor 200, a double-ended lead screw 201, a sliding plate 204, and a first threaded seat 205. The first motor 200 is mounted on the bottom of the base 1; the double-ended lead screw 201 is horizontally disposed at the bottom of the base 1, with one end fixed to the output shaft of the first motor 200 and the other end rotatably connected to the base 1; one end of the sliding plate 204 passes through the groove 11 and is fixedly connected to the second moving component 21; the first threaded seat 205 is fixed to the other end of the sliding plate 204, and the first threaded seat 205 is sleeved on the surface of the double-ended lead screw 201 and threadedly connected to the double-ended lead screw 201. In this embodiment, two sliding plates 204 are provided, located at both ends of the double-ended lead screw 201, and both are connected to the double-ended lead screw 201 through the first threaded seat 205. When the first motor 200 operates and the double-ended lead screw 201 rotates forward or backward, the relative distance between the two sliding plates 204 decreases or increases. The slide plate 204 is provided with a slide groove 11 and can slide within the slide groove 11. The slide groove 11 limits the slide plate 204 and can prevent the slide plate 204 from rotating during movement.

[0036] In this embodiment, to further ensure the stability of the slide plate 204 during movement, the first moving component 20 further includes a fixed plate 202, a limiting rod 203, and a limiting seat 206. The fixed plate 202 is fixed to both sides of the bottom end of the base 1. Along the length extension direction of the base 1, the limiting rod 203 is fixed between two adjacent fixed plates 202. The limiting seat 206 is fixed to the other end of the slide plate 204, and the limiting seat 206 is sleeved on the surface of the limiting rod 203 and slidably connected to the limiting rod 203. Four fixed plates 202 are provided. Along the length extension direction of the base 1, two adjacent fixed plates 202 form a group, and a limiting rod 203 is fixed between a group of fixed plates 202. Two groups of fixed plates 202 are provided on both sides of the double-ended screw 201. Two limiting seats 206 are fixed on the slide plate 204, so that the first threaded seat 205 is located between the two limiting seats 206. The limiting seat 206 is fitted with the limiting rod 203 and is slidably connected to the limiting rod 203. When the slide plate 204 moves, the limiting seat 206 works with the limiting rod 203 to further limit the slide plate 204, which can prevent the slide plate 204 from rotating during the movement and improve the stability of the slide plate 204 during the movement.

[0037] In some other possible embodiments, the first moving component 20 includes a first motor 200, a double-ended lead screw 201, a sliding plate 204, and a first threaded seat 205. The first motor 200 is mounted on the bottom of the base 1; the double-ended lead screw 201 is horizontally disposed at the bottom of the base 1, with one end fixed to the output shaft of the first motor 200 and the other end rotatably connected to the base 1; the sliding plate 204 includes an upper plate and a lower plate, which are separated from the base 1, i.e., the upper plate is disposed at the top of the base 1, and the bottom end of the upper plate is slidably connected to the base 1, the upper plate is fixedly connected to the second moving component 21, and the lower plate is disposed at the bottom of the base 1; the first threaded seat 205 is fixed to the lower plate, and the lower plate is connected to the upper plate on both sides by connecting rods, and the connecting rods are disposed along the width direction of the base 1. Figure 2 On both sides of the double-ended lead screw 201 (in the Z direction), the first threaded seat 205 is sleeved on the surface of the double-ended lead screw 201 and threadedly connected to the double-ended lead screw 201. In this embodiment, there are two upper plates and two lower plates, and each lower plate is connected to each upper plate through a connecting rod. The two lower plates are located at both ends of the double-ended lead screw 201 and are connected to the double-ended lead screw 201 through the first threaded seat 205. When the first motor 200 works and the double-ended lead screw 201 rotates forward or backward, the two lower plates drive the two upper plates to move, and the relative distance between the two upper plates decreases or increases. Since the upper plates, lower plates and connecting rods form a "U"-shaped frame structure, the upper plates, lower plates and connecting rods can move smoothly horizontally when moving. In this embodiment, it is not necessary to open the sliding groove 11 on the base 1, which reduces the manufacturing process of the base 1.

[0038] Based on the above embodiments, in this embodiment, the second moving component 21 includes a vertical groove 210, a second motor 211, a screw 212, and a second threaded seat 213. The vertical groove 210 is vertically arranged on the base 1 and is fixedly connected to the first moving component 20. The second motor 211 is installed at the top of the vertical groove 210. The screw 212 is disposed inside the vertical groove 210, and one end of the screw 212 is fixedly connected to the output end of the second motor 211. One end of the second threaded seat 213 is sleeved on the surface of the screw 212 and threadedly connected to the screw 212, and the other end passes through one side of the vertical groove 210.

[0039] In this embodiment, when the second motor 211 is working, it drives the screw 212 to rotate. When the screw 212 rotates forward or backward, it drives the second threaded seat 213 to move up or down relative to the vertical groove 210. The vertical groove 210 is connected to the sliding plate 204. When the sliding plate 204 moves, it can drive the vertical groove 210 to move.

[0040] Based on the above embodiments, in this embodiment, the rotating assembly 22 further includes a third motor 220, which is mounted on the second threaded seat 213. The turntable 221 is fixed to one end of the second threaded seat 213, and the output end of the third motor 220 passes through one end of the turntable 221 and is fixedly connected to the clamping plate 222. A portion of the third motor 220 is embedded inside the second threaded seat 213, and another portion is embedded inside the turntable 221. The output shaft of the third motor 220 passes through one end of the turntable 221 and is then connected to the clamping plate 222. The clamping plate 222 and the turntable 221 are coaxially arranged. When the third motor 220 operates, driving the clamping plate 222 and the workpiece to rotate, the turntable 221 remains stationary. The angle of rotation between the clamping plate 222 and the workpiece can be clearly seen through the scale markings on the turntable 221, allowing for the marking of images, text, numbers, or lines on different surfaces of the workpiece.

[0041] To further improve the accuracy of adjusting the workpiece rotation angle, a first pointer 224 and a first camera 223 are provided on the clamping plate 222. The first pointer 224 is positioned between the first camera 223 and the turntable 221, and the first pointer 224 is in contact with the turntable 221. By observing the initial and final positions of the first pointer 224, the rotation angle of the workpiece can be determined. The first camera 223 is used to capture images of the first pointer 224 and the scale marks on the turntable 221. The first camera 223 is electrically connected to a computer, and the images captured by the first camera 223 are transmitted to the computer for display, allowing the operator to observe the rotation angle of the workpiece via the computer.

[0042] Based on the above embodiments, in this embodiment, the second fixing device 3 includes a fixing plate 31, a fourth motor 30, a second pointer 32, and a second camera 33. The fixing plate 31 is rotatably connected to the mounting groove 12; the fourth motor 30 is installed at the bottom end of the base 1, and one end of the output shaft of the fourth motor 30 passes through the inner wall of the mounting groove 12 and is fixedly connected to the fixing plate 31; the second pointer 32 is fixed to the bottom end of the fixing plate 31 and is in contact with the inner wall of the mounting groove 12; the second camera 33 is fixed to the bottom end of the fixing plate 31 and is located at the top of the second pointer 32. When the fourth motor 30 is working, it drives the fixing plate 31 to rotate. The bottom end of the inner wall of the mounting groove 12 is provided with a scale mark, and the second pointer 32 is in contact with the bottom end of the inner wall of the mounting groove 12. By setting a second camera 33, the second pointer 32 and the scale mark at the bottom of the inner wall of the mounting groove 12 are photographed. The second camera 33 is electrically connected to the computer. The images of the initial and final positions of the second pointer 32 captured by the second camera 33 are transmitted to the computer for display, so that the operator can determine the rotation angle of the workpiece.

[0043] When the base 1 is provided with a sliding groove 11, the sliding groove 11 is located at both ends of the mounting groove 12 and is connected to the mounting groove 12. The sliding plate 204 passes through the sliding groove 11. A through groove 34 is provided on the fixed plate 31. The width of the through groove 34 is the same as the width of the sliding groove 11. The through groove 34 is located on both sides of the fixed plate 31, and the sliding groove 11 is also located on both sides of the fixed plate 31. When the fixed plate 31 is rotated to the initial position, the sliding groove 11 is connected to the through groove 34, so that the sliding plate 204 can slide into the through groove 34 when moving. When the first fixing device 2 fixes a hard workpiece, the second fixing device 3 is not used; when the second fixing device 3 fixes a soft workpiece, the first fixing device 2 is not used; after the second fixing device 3 is used, the fixed plate 31 needs to be rotated to the initial position to facilitate the subsequent fixation of the hard workpiece by the first fixing device 2.

[0044] To facilitate the fixing of soft workpieces on the fixing plate 31, the fixing plate 31 is provided to include a first fixing layer 310 and a second fixing layer 311. The top of the first fixing layer 310 is located on the same horizontal plane as the top of the base 1. The first fixing layer 310 is made of rubber. After the soft workpiece is placed on the top of the first fixing layer 310, it can be fixed to the top of the first fixing layer 310 with a thumbtack.
