[0023] like Figures 1 to 5 As shown, the utility model provides a visual laser marking machine, which includes a machine platform 1, a conveying track 2 arranged on the machine platform 1, a conveying mechanism 3 arranged on the conveying track 2, a loading device 4, a marking device 5 and a unloading device 6 arranged in sequence along the conveying direction of the conveying mechanism 3, and a position adjustment device 7 arranged on the machine platform 1, wherein the position adjustment device 7 is used to drive the marking device 5 to move relative to the machine platform 1; the loading device 4 is used to convey the material to the conveying mechanism 3, and the conveying mechanism 3 is used to convey the material output by the loading device 4 along the conveying track 2 to the marking device 5 and the unloading device 6 in sequence; the marking device 5 is used to position and mark the material conveyed by the conveying mechanism 3; and the unloading device 6 is used to unload the material on the conveying mechanism 3.

[0024] The utility model can realize the marking of materials such as mobile phone keys and blister trays. When the mobile phone keys need to be marked, the loading device 4 conveys the mobile phone keyboard to the conveying mechanism 3, and the conveying mechanism 3 drives the mobile phone keyboard to move along the conveying track 2 to the marking device 5, and the position of the marking device 5 is adjusted by the position adjustment device 7. The marking device 5 marks the blister tray, and then the conveying mechanism 3 drives the mobile phone keyboard to move to the unloading device 6. The unloading device 6 removes the mobile phone keys after marking, thereby realizing full-automatic marking. The structure of the utility model is simple and compact, and the conveying mechanism 3, the loading device 4 and the unloading device 6 are convenient to cooperate, so as to realize the full-automatic marking of the mobile phone keyboard, and the marking steps are simple and the degree of automation is high. The conveying mechanism 3 is added to make the flow of materials between each station smoother.

[0025] Furthermore, the visual laser marking machine also includes a backlight unit 8 , and the backlight unit 8 can be placed on the conveying track 2 .

[0026] The utility model can realize the free switching marking of materials such as mobile phone buttons and blister trays. Specifically, the backlight unit 8 can adopt the structure of the existing backlight plate plus backlight source, which will not be repeated here. When it is necessary to mark the blister tray, the feeding device 4 and the unloading device 6 are suspended, and the backlight unit 8 is manually placed at a suitable position of the conveying track 2, and then the blister tray to be marked is manually placed on the backlight unit 8, and the position of the marking device 5 is adjusted by the position adjustment device 7. The backlight unit 8 can mark the position where the blister plate needs to be marked, and finally the blister tray is marked by the marking device 5. When it is not necessary to cooperate with the conveying mechanism 3, the feeding device 4 and the unloading device 6 to load and unload, the backlight unit 8 can be directly placed on the conveying track 2, and the placement of the backlight unit 8 will not interfere with the conveying mechanism 3, the feeding device 4 and the unloading device 6. The backlight unit 8 cooperates with the marking device 5 to position and mark the blister plate, and the marking station of the utility model is fully utilized, and different materials are marked, and the utilization rate is high.

[0027] Furthermore, the conveying mechanism 3 includes a belt transmission assembly 9 rotatably disposed on the conveying track 2 and a belt drive 10 disposed on the conveying track 2, and the belt drive 10 is used to drive the belt transmission assembly 9 to rotate relative to the conveying track 2; the material and the backlight unit 8 can be placed on the belt transmission assembly 9 respectively.

[0028] In actual use, the belt drive 10 can adopt the existing motor plus gear structure, and the belt transmission assembly 9 can adopt the existing transmission wheel and belt structure. The belt drive 10 drives the belt transmission assembly 9 to rotate on the conveying track 2, and the rotating belt transmission assembly 9 drives the material to move, thereby completing the loading and unloading of the material. The structure of the conveying mechanism 3 is simple and the material conveying is convenient. The belt transmission assembly 9 is recessed on the conveying track 2, so that the arrangement of the belt transmission assembly 9 on the conveying track 2 will not affect the stable placement of the backlight unit 8.

[0029] Furthermore, the loading device 4 includes a loading bin 11 mounted on the conveying track 2 and a lifting mechanism 12 arranged on the conveying track 2, the loading bin 11 is used to store materials to be marked, and the bottom opening of the loading bin 11 is located above the conveying mechanism 3; the material at the bottom of the loading bin 11 can fall onto the conveying mechanism 3, and the lifting mechanism 12 can protrude into the loading bin 11 and lift the material stored in the loading bin 11.

[0030] In actual use, multiple layers of mobile phone keys are stored in the upper bin 11 respectively, and the mobile phone keys of the bottom layer naturally fall to the belt drive assembly 9 below under the action of gravity, and then the lifting mechanism 12 protrudes into the upper bin 11, and drives the stacked mobile phone keys in the upper bin 11 to move upward, so that other materials are no longer pressed on the mobile phone keys of the bottom layer, so that the conveying mechanism 3 can convey the mobile phone keys above it to the marking device 5. When continuing to feed, the lifting mechanism 12 moves downward to reset and then retracts from the upper bin 11. At this time, the mobile phone keys at the bottom of the upper bin 11 will naturally fall to the conveying mechanism 3 under the action of gravity, thereby completing the feeding. The structure of the feeding device 4 is simple and the feeding is convenient.

[0031] Furthermore, the loading bin 11 includes two second loading columns 14, two first loading columns 13 respectively connected to the conveying track 2, and at least two loading connecting rods 15, and the first loading columns 13 and the second loading columns 14 are respectively connected by the loading connecting rods 15; the gap between the second loading columns 14 and the conveying mechanism 3 can allow materials to pass through. The two second loading columns 14 and the two first loading columns 13 are surrounded by a material accommodating space.

[0032] In actual use, after the material at the bottom of the loading bin 11 falls to the belt drive assembly 9, the material is driven to move by the belt drive assembly 9, and the second loading column 14 is suspended. The belt drive assembly 9 can drive the material to pass through the gap between the second loading column 14 and the conveying mechanism 3, so that the material is directly conveyed to the marking device 5. The loading bin 11 and the conveying track 2 are easy to install, and the material will not interfere with the loading bin 11 during the material conveying process.

[0033] Furthermore, the lifting mechanism 12 includes a first lifting driver 16 arranged on the conveying track 2, a second lifting driver 17 arranged at the output end of the first lifting driver 16, and an insert plate 18 arranged at the output end of the second lifting driver 17, and the insert plate 18 can protrude into the upper bin 11.

[0034] In actual use, the first lifting driver 16 and the second lifting driver 17 can both be cylinders or linear motors. The first lifting driver 16 drives the insert plate 18 to move along the Y axis and insert it into the upper bin 11, so that the insert plate 18 is located at the bottom of the multi-layer material, and then the second lifting driver 17 drives the first lifting driver 16, the insert plate 18 and the material above the insert plate 18 to move upward along the Z axis synchronously to lift the material, so that the belt drive assembly 9 can transport the material above it to the marking device 5. The number of lifting mechanisms 12 can be set to multiple, and multiple lifting mechanisms 12 are symmetrically arranged on the surrounding side of the upper bin 11 to improve the stability during the lifting process. Specifically, the structure and function of the unloading device 6 are the same or similar to those of the loading device 4. The material is transported to the bottom of the unloading device 6 via the belt drive assembly 9. The lifting mechanism on the unloading device 6 can lift the material so that the material leaves the belt drive assembly 9, thereby completing the unloading of the material, which will not be repeated here.

[0035] Furthermore, the visual laser marking machine also includes a blocking device 22 arranged in the middle of the conveying track 2, and the blocking device 22 can be used to block the material conveyed by the conveying mechanism 3.

[0036] Specifically, the number of the blocking devices 22 is set to be multiple, and the blocking device 22 includes a blocking driver 23 arranged in the middle of the conveying track 2 and a blocking block 24 arranged at the output end of the blocking driver 23, and the blocking block 24 can conflict with the material on the belt drive assembly 9. The blocking driver 23 can adopt an existing cylinder. In actual use, the blocking driver 23 drives the blocking block 24 to protrude above the belt drive assembly 9. When the belt drive assembly 9 conveys the material to the side of the blocking block 24, the blocking block 24 can resist and limit the material, so that the material stops continuing to be conveyed and waits to meet the standard. The addition of the blocking device 22 improves the accuracy of the material when it is conveyed to the marking position, which is convenient for precise positioning.

[0037] Furthermore, the position adjustment device 7 includes an X-axis adjustment mechanism 19 arranged on the machine 1, a Z-axis adjustment mechanism 20 arranged at the output end of the X-axis adjustment mechanism 19, and a Y-axis adjustment mechanism 21 arranged at the output end of the Z-axis adjustment mechanism 20, and the marking device 5 is arranged at the output end of the Y-axis adjustment mechanism 21.

[0038] Specifically, the X-axis adjustment mechanism 19, the Y-axis adjustment mechanism 21 and the Z-axis adjustment mechanism 20 can all adopt existing linear drive modules. In actual use, the X-axis adjustment mechanism 19 drives the Z-axis adjustment mechanism 20, the Y-axis adjustment mechanism 21 and the marking device 5 to reciprocate along the X-axis direction on the machine 1, the Z-axis adjustment mechanism 20 drives the Y-axis adjustment mechanism 21 and the marking device 5 to reciprocate along the Z-axis direction on the machine 1, and the Y-axis adjustment mechanism 21 drives the marking device 5 to reciprocate along the Y-axis direction on the machine 1, thereby adjusting the position of the marking device 5, and then accurately positioning the marking position of the material. The position adjustment device 7 can accurately and stably adjust the position of the marking device 5. The X-axis adjustment mechanism 19, the Z-axis adjustment mechanism 20 and the Y-axis adjustment mechanism 21 facilitate the position adjustment of the marking device 5.

[0039] Furthermore, the marking device 5 includes a laser marking module and a camera positioning module, and the laser marking module and the camera positioning module are both existing equipment and will not be described in detail here.

[0040] All technical features in this embodiment can be freely combined according to actual needs.
