[0002] UV laser marking machine belongs to the series of laser marking machines, but it is developed with 355nm UV laser. The machine adopts the third-order intracavity frequency doubling technology. Compared with infrared laser, the 355nm UV light focus spot is very small, which can greatly reduce the mechanical deformation of the material and has little effect of processing heat. Because it is mainly used for ultra-fine marking and engraving, it is particularly suitable for marking food and medical packaging materials, drilling microholes, high-speed division of glass materials, and complex graphic cutting of silicon wafers. For example, a Chinese patent document with publication number CN214109233U discloses a UV laser marking machine, which includes a cabinet and a crossbeam. The bottom of the cabinet is fixedly installed with a walking wheel through a base, and a desktop is fixedly installed on the top of the cabinet. The support column passes through the crossbeam at the central position of the top of the desktop. Both sides of the bottom of the crossbeam are provided with a mounting cavity. The first screw is rotatably installed inside the mounting cavity. The first screw is driven and installed with a first mounting plate through a transmission kit. The bottom of the first mounting plate is installed with a mounting groove. The inside of the mounting groove is rotatably installed with a guide block through a second screw. The front of the mounting groove is installed with a servo motor connected to the second screw. The guide block is slidably installed with a laser transmitter through the second mounting plate. A processing table is installed on both sides of the top of the desktop. A mounting frame is slidably installed on both sides of the top of the processing table, and a fastening knob for matching is provided on the mounting frame. In this way, the deviation of materials caused by external factors is solved and the workload is effectively improved. Among them, the existing ultraviolet laser marking machine has processing tables installed on both sides of the top of the table, and mounting frames are slidably installed on both sides of the top of the processing table, and the mounting frames are provided with matching fastening knobs. In this way, the material can be fixed by sliding and adjusting the fastening knobs on the processing table.

[0040] like Figures 1 to 6 , Figures 9 to 12 As shown, in one embodiment, a multifunctional marking machine 1 includes a frame 10, a laser mechanism 20 and a supporting mechanism 30. The laser mechanism 20 is arranged on the frame 10. The laser mechanism 20 is used to mark the workpiece 40. The supporting mechanism 30 includes a base plate 31, a right-angle block 32, a supporting member 33, two limit members 34 and a plurality of positioning members 35. The base plate 31 is arranged on the frame 10, the supporting member 33 is arranged on the base plate 31, the right-angle block 32 is arranged at one of the four corners of the base plate 31, the right-angle block 32 is used to abut against two adjacent sides of the supporting member 33, the two limit members 34 are both slidably arranged on the base plate 31, the two limit members 34 are used to push the other two adjacent sides of the supporting member 33, and the positioning members 35 are respectively and equidistantly penetrated on the supporting member 33. When the workpiece 40 is placed on the supporting mechanism 30 , the workpiece 40 is used to press down the contacted part of the positioning members 35 , so that the remaining non-contacted positioning members 35 can limit the workpiece 40 .

[0041] It should be noted that the bottom plate 31 is arranged on the frame 10, the supporting member 33 is arranged on the bottom plate 31, the right-angle block 32 is arranged on one of the four corners of the bottom plate 31, and the two inner side surfaces of the right-angle block 32 are fitted with the two adjacent side surfaces of one of the four corners of the bottom plate 31, wherein the height of the right-angle block 32 is greater than the height of the bottom plate 31, and when the supporting member 33 is placed on the bottom plate 31, two adjacent side edges of the supporting member 33 abut against the right-angle block 32. Further, two stoppers 34 are both slidably arranged on the bottom plate 31, and the two stoppers 34 push the other two adjacent side edges of the supporting member 33 respectively, so that when the supporting member 33 is placed on the bottom plate 31, the two stoppers 34 push the two adjacent side edges of the supporting member 33 respectively, and the other two adjacent side edges of the supporting member 33 abut against the right-angle block 32, so that the supporting member 33 is fixed on the bottom plate 31. Furthermore, each positioning member 35 is equidistantly penetrated on the supporting member 33, wherein one end of the positioning member 35 is located in the supporting member 33, and the other end of the positioning member 35 extends out of the top surface of the supporting member 33, so that one end of multiple positioning members 35 extends out from the top surface of the supporting member 33. Since each positioning member 35 is equidistantly penetrated on the supporting member 33, each positioning member 35 can slide longitudinally relative to the supporting member 33. When the workpiece 40 is placed on the supporting member 33, the workpiece 40 first contacts with one end of each positioning member 35 extending out of the top surface of the supporting member 33, and due to the gravity of the workpiece 40, The workpiece 40 will exert downward pressure on the contacted part of the positioning member 35, so that the part of the positioning member 35 is pressed into the supporting member 33, and the remaining part of the positioning member 35 that is not in contact with the workpiece 40 will remain in an extended state along the four sides of the contact area. Since each positioning member 35 slides longitudinally relative to the supporting member 33, the workpiece 40 cannot move horizontally after pressing down the part of the positioning member 35, so that the workpiece 40 is fixed on the supporting member 33. In this way, by setting up multiple positioning members 35, various irregularly shaped workpieces can be fixed without having to adjust the fixed position of the workpiece multiple times. In one embodiment, for example, the workpiece 40 is a cylinder 351, and a circular surface in the cylinder 351 presses the part of the contact positioning member 35 into the supporting member 33, and the remaining positioning members 35 that are not in contact with the circular surface will remain extended along the four sides of the circular surface, so that the cylinder 351 is fixed on the supporting member 33.

[0042] like Figures 4 to 6 As shown, in one embodiment, the supporting member 33 includes a lower plate 332 and an upper plate 331, the lower plate 332 is arranged on the bottom plate 31, the upper plate 331 is arranged on the lower plate 332, and a partition is formed between the upper plate 331 and the lower plate 332, and each positioning member 35 is penetrated on the upper plate 331.

[0043] It should be noted that the upper plate 331 is arranged on the lower plate 332, and the two opposite ends of the lower plate 332 are provided with convex strips 3321, and the two convex strips 3321 are respectively connected to the opposite ends of the upper plate 331, so that a partition is formed between the upper plate 331 and the lower plate 332. Further, a plurality of circular holes are opened on the upper plate 331, and one end of each positioning member 35 passes through the circular hole and extends out of the top surface of the upper plate 331, and the other end of each positioning member 35 is located in the partition between the upper plate 331 and the lower plate 332. It should be noted that the height of the convex strips 3321 is greater than the height of the positioning member 35. When the part of the positioning member 35 extending out of the top surface of the upper plate 331 is pressed down by the workpiece 40, the positioning member 35 can completely slide into the partition, so that the workpiece 40 can fit with the top surface of the upper plate 331, and then the upper plate 331 supports the workpiece 40.

[0044] like Figures 4 to 8 As shown, in one embodiment, the positioning member 35 includes a column 351 and an elastic body 352. The column 351 is penetrated through the upper plate 331 so that one end of the column 351 is located in the partition and the other end of the column 351 extends from the top surface of the upper plate 331. The elastic body 352 is respectively abutted against the lower plate 332 and the column 351. The elastic body 352 is used to push the column 351 away from the lower plate 332.

[0045] It should be noted that an inner groove 3511 is provided at one end of the column 351, and the end of the column 351 with the inner groove 3511 is located in the interlayer, and the other end of the column 351 extends out through the circular hole on the upper plate 331. When the column 351 is pressed down by the workpiece 40, the column 351 can slide longitudinally relative to the upper plate 331. Further, the elastic body 352 is located in the interlayer, and one end of the elastic body 352 is sleeved with the inner groove 3511 at one end of the column 351, and the other end of the elastic body 352 is in contact with the inner side surface of the lower plate 332, so that the elastic body 352 can push the column 351 away from the lower plate 332, thereby making the elastic body 352 keep the pushing column 351 extending out of the top surface of the upper plate 331.

[0046] like Figure 7 As shown, in one embodiment, a rubber head 353 is provided at one end of the column 351 away from the elastic body 352 .

[0047] It should be noted that since the workpiece 40 needs to contact part of the column 351, in order to avoid scratches on the workpiece 40 when the workpiece 40 contacts the column 351, a rubber head 353 is provided at the end of the column 351 that contacts the workpiece 40. For example, the rubber head 353 is glued to one end of the column 351 by glue.

[0048] like Figures 9 and 10As shown, in one embodiment, two slide grooves 311 are provided on the bottom plate 31 , and two stoppers 34 are slidably disposed on the two slide grooves 311 , respectively.

[0049] When the cam 32 is in the closed position, the two stoppers 34 are swung to the left of the two stoppers 34 so that the cam 32 can be easily moved when the cam 32 is in the closed position.

[0050] like Figures 9 to 11 As shown, in one embodiment, the limiting member 34 includes a slide rail 341 and a slide seat 342 . The slide rail 341 is disposed in the slide groove 311 , and the slide seat 342 is slidably disposed on the slide rail 341 .

[0051] It should be noted that the slide rail 341 is arranged in the slide groove 311. For example, the slide rail 341 is screwed in the slide groove 311 by screws, and the slide seat 342 is slidably arranged on the slide rail 341, so that the slide seat 342 can slide close to the supporting member 33 or slide away from the supporting member 33, thereby making the limit member 34 close to or away from the supporting member 33.

[0052] like Figure 11 to Figure 12 As shown, in one embodiment, the limiting member 34 further includes a supporting block 343 , one end of the supporting block 343 is rotatably disposed on the sliding seat 342 , and the supporting block 343 is used to abut against the workpiece 40 .

[0053] It should be noted that the support block 343 includes a vertical block 3431 and a pivot block 3432. One end of the pivot block 3432 is arranged at one end of the slider close to the supporting member 33, and the other end of the pivot block 3432 is rotatably connected to one end of the vertical block 3431. For example, the other end of the pivot block 3432 is connected to one end of the vertical block 3431 through a pin, so that the vertical block 3431 can rotate relative to the slide 342. Furthermore, since the two limit members 34 respectively push the supporting member 33 away from the two adjacent sides of the right-angle block 32, the two vertical blocks 3431 are also close to the two adjacent sides of the supporting member 33. When the two vertical blocks 3431 are rotated into a vertical state, the workpiece 40 can be fixed more stably. For example, when the workpiece 40 is a spherical structure, when the sphere is placed on the supporting member 33, the sphere will press down on the partially contacted column 351, so that the contact surface between the sphere and the partial column 351 is in an arc shape, and the force of the sphere pressing down on the partially contacted column 351 gradually decreases from the center point of the arc shape outward, so that the partially contacted column 351 forms a bowl shape, and the remaining columns 351 that are not in contact with the sphere keep extending out of the supporting member 33 along the contact area between the sphere and the partial column 351, so that the sphere is fixed on the supporting member 33. Furthermore, since the sphere has a certain height, the two vertical blocks 3431 jointly abut the sphere, so that the spherical workpiece 40 can be reliably fixed on the supporting member 33.

[0054] like Figure 11 to Figure 12 As shown, in one embodiment, a rubber sheet 3433 is provided on one side of the support block 343 close to the supporting member 33 .

[0055] It should be noted that since the support block 343 needs to contact the workpiece 40, in order to avoid scratches on the workpiece 40 when the support block 343 contacts the workpiece 40, a rubber head 353 is provided at the end of the support block 343 that contacts the workpiece 40. For example, the rubber head 353 is glued to the side of the support block 343 close to the supporting member 33 by glue.

[0056] like Figures 4 to 8 As shown, in one embodiment, the elastic body 352 is a spring.

[0057] It should be noted that, in order to enable the elastic body 352 to push the column 351 and the lower plate 332 in one direction and enable the inner groove 3511 on the column 351 to be sleeved with the elastic body 352 , the elastic body 352 is configured as a spring structure.

[0058] like Figure 1 As shown, in one embodiment, the laser mechanism 20 includes a lifting module 21 and a laser 22 . The lifting module 21 is disposed on the frame 10 , the laser 22 is disposed on the output shaft of the lifting module 21 , and the laser 22 is located above the supporting mechanism 30 .

[0059] It should be noted that the lifting module 21 is vertically arranged on the frame 10 and is screwed to the frame 10 by screws. The laser 22 is slidably arranged on the output shaft of the lifting module 21, so that the laser 22 can slide relative to the lifting module 21. Since the laser 22 is located above the supporting mechanism 30, the laser 22 can slide close to the supporting mechanism 30 or slide away from the supporting mechanism 30. In this way, according to the size and shape of the workpiece 40, the laser focus on the workpiece 40 can be adjusted by adjusting the laser 22 to slide close to or away from the supporting mechanism 30 to ensure the quality of laser marking. Among them, the lifting module 21 can be a screw slide rail module.

[0060] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
