[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] As shown in Figures 1 to 6, this utility model provides a double-sided laser engraving machine, comprising:

[0033] Top plate 1, top of top plate 1 is provided with button 2, and top plate 1 is provided with sliding groove 3;

[0034] A fixing mechanism is installed at the top of the top plate 1;

[0035] A clamping mechanism is provided at the bottom of the top plate 1;

[0036] The clamping mechanism includes a fixed frame 4, the top of which is fixedly connected to the bottom of the top plate 1. A first motor 5 is fixedly installed at the bottom of the fixed frame 4. A first screw 6 is fixedly sleeved at the output end of the first motor 5. The top of the first screw 6 is movably sleeved inside the bottom of the top plate 1. A moving block 7 is threadedly sleeved on the outer surface of the first screw 6. A first hinge block 8 is fixedly installed at the top of the moving block 7. A moving rod 9 is hinged inside the first hinge block 8. A second hinge block 10 is hinged at the end of the moving rod 9 away from the first hinge block 8. A moving block 11 is fixedly installed at the top of the second hinge block 10. The outer surface of the moving block 11 is slidably connected to the inside of the slide groove 3. A clamping plate 12 is fixedly installed on the outer surface of the moving block 11.

[0037] When the first motor 5 is running, the first screw 6 will rotate. Since the first screw 6 is threadedly connected to the moving block 7, the first screw 6 will drive the two first hinge blocks 8 to move through the moving block 7. Then, the two first hinge blocks 8 will pull the two second hinge blocks 10 through the two moving rods 9, so that the two second hinge blocks 10 will drive the two movable blocks 11 to move towards each other along the inside of the two slide grooves 3. At the same time, the two clamping plates 12 will move towards each other under the drive of the two movable blocks 11. When the two clamping plates 12 come into contact with the product during the opposite movement, they will clamp and fix the product, thereby automatically clamping and fixing products of different sizes to be engraved.

[0038] The fixed mechanism includes:

[0039] The bottom end of the fixed plate 13 is fixedly connected to the top end of the top plate 1. A round rod 14 is movably sleeved inside the fixed plate 13. A clamping block 15 is fixedly installed at the end of the round rod 14 away from the fixed plate 13.

[0040] Spring 16, one end of spring 16 is fixedly connected to the outer surface of clamping block 15, and the other end of spring 16 is fixedly connected to the outer surface of fixing plate 13.

[0041] Because the two clamping blocks 15 are designed with an inclination, when the operator places the product above the gap between the two clamping blocks 15 and presses it, the bottom of the product will squeeze and push the two clamping blocks 15, causing the two clamping blocks 15 to drive the two sets of round rods 14 to move in opposite directions along the inside of the two fixed plates 13. At this time, the two sets of springs 16 will be compressed. Due to the design of the springs 16, when the product is between the two clamping blocks 15, the two clamping blocks 15 will be able to squeeze and fix the product to achieve the effect of initial fixation of the product. When the product is between the two clamping blocks 15, it will squeeze and push the button 2, causing the button 2 to retract into the inside of the top of the top plate 1. When the button 2 is completely retracted into the inside of the top of the top plate 1, the button 2 will send a signal to the controller, and the controller will then make the first motor 5 run.

[0042] The top plate 1 has a fixed cylinder 17 fixedly installed at the bottom end, and a base 18 is movably sleeved on the outer surface of the fixed cylinder 17.

[0043] Because the fixed cylinder 17 is internally and movably connected to the top of the base 18, the fixed cylinder 17 can rotate inside the base 18. When the fixed cylinder 17 rotates, it will drive the top plate 1 to rotate as a whole. At this time, the product will rotate and flip under the drive of the top plate 1.

[0044] The base 18 has a bracket 19 fixedly installed at its top, a fourth motor 32 fixedly installed at its top, a rotating shaft 20 fixedly connected to the output end of the fourth motor 32, and a gear 21 fixedly connected to the outer surface of the rotating shaft 20.

[0045] When the fourth motor 32 is running, the shaft 20 will drive the gear 21 to rotate.

[0046] Among them, the outer surface of the gear 21 is meshed with a toothed ring 22, and the inside of the toothed ring 22 is fixedly sleeved with the outer surface of the fixed cylinder 17.

[0047] Since the outer surface of gear 21 meshes with the outer surface of gear ring 22, when gear 21 rotates, it will drive gear ring 22 to rotate. At this time, fixed cylinder 17 will rotate under the drive of gear ring 22.

[0048] The base 18 has a stop bar 33 fixedly installed at its top, and the outer surface of the stop bar 33 is in contact with the outer surface of the top plate 1.

[0049] Due to the design of the lever 33, the overall rotational stroke of the top plate 1 is limited, so that the maximum rotational stroke of the top plate 1 is 180 degrees.

[0050] Among them, a support 23 is fixedly installed on the right side of the top of the base 18, a first slide rail 24 is fixedly installed on the top of the support 23, a second motor 25 is fixedly installed on the front of the first slide rail 24, and a second screw 26 is fixedly sleeved on the output end of the second motor 25.

[0051] When the second motor 25 is running, the second screw 26 will rotate.

[0052] The second screw 26 has a second slide rail 27 threaded onto its outer surface, and the outer surface of the second slide rail 27 is slidably connected to the inside of the first slide rail 24.

[0053] Due to the internal design of the first slide rail 24, the movement of the second slide rail 27 is limited, so that the second slide rail 27 can only move left and right along the inside of the first slide rail 24. Since the second screw 26 is threadedly connected to the inside of the second slide rail 27, when the second screw 26 rotates, it will drive the second slide rail 27 to move left and right along the inside of the first slide rail 24.

[0054] The top of the second slide rail 27 is fixedly mounted with a third motor 28, and the output end of the third motor 28 is fixedly sleeved with a third screw 29.

[0055] When the third motor 28 is running, the third screw 29 will rotate.

[0056] Among them, the outer surface of the third screw 29 is threaded with a lifting block 30, the outer surface of the lifting block 30 is slidably connected to the inside of the second slide rail 27, and a laser engraving head 31 is fixedly installed on the left side of the lifting block 30.

[0057] Since the outer surface of the third screw 29 is threadedly connected to the inner thread of the lifting block 30, when the third screw 29 rotates, it will drive the lifting block 30 to move up and down along the inside of the second slide rail 27. At this time, the lifting block 30 will drive the laser engraving head 31 to move up and down.

[0058] Working principle and usage process of this utility model:

[0059] When the operator needs to laser engrave the product, the operator first places the product above the gap between the two clamping blocks 15, and then presses the product down, so that the bottom of the product squeezes and pushes the two clamping blocks 15. Since the two clamping blocks 15 are designed with an inclination, the two clamping blocks 15 will move under the squeezing and pushing of the product. At this time, the two sets of round rods 14 will move along the inside of the two fixed plates 13 driven by the two clamping blocks 15. Due to the internal design of the fixed plates 13, the movement of the two sets of round rods 14 will be limited. At this time, the two sets of round rods 14 will move in opposite directions driven by the two clamping blocks 15. During this process, the two sets of springs 16 will be compressed. Due to the design of the springs 16, when the product is located between the two clamping blocks 15, the two clamping blocks 15 will be able to squeeze the product to achieve the effect of initial fixation of the product.

[0060] When the product is positioned between the two clamping blocks 15, the bottom of the product presses down on button 2, causing button 2 to retract into the top of the top plate 1. When button 2 is fully retracted into the top of the top plate 1, button 2 sends a signal to the built-in controller of the device. At this time, the controller will cause the first motor 5 to run, and the first screw 6 will rotate. Since the outer surface of the first screw 6 is engaged with the internal thread of the moving block 7, the rotation of the first screw 6 will drive the moving block 7 to move downward. At this time, the moving block 7 will drive the two moving rods 9 to move through the two first hinge blocks 8. The other end of the rod 9 will pull the two second hinge blocks 10 respectively, so that the two second hinge blocks 10 drive the two movable blocks 11 to move. Due to the internal design of the slide groove 3, the movement of the movable blocks 11 will be limited. At this time, the two movable blocks 11 will move towards each other along the inside of the two slide grooves 3, and the two clamping plates 12 will move towards each other under the drive of the two movable blocks 11. Then, the two clamping plates 12 will contact the product in the opposite direction. At this time, the two clamping plates 12 will clamp and fix the product, thus realizing the function of automatically clamping and fixing products of different sizes to be engraved.

[0061] After the product is fixed, the operator starts the second motor 25 and the third motor 28 according to the usage requirements. When the second motor 25 runs, the second screw 26 will rotate. Since the second screw 26 is threadedly connected to the second slide rail 27, when the second screw 26 rotates, it will drive the second slide rail 27 to move left and right along the inside of the first slide rail 24. At this time, the second slide rail 27 will drive the laser engraving head 31 to move left and right through the lifting block 30, so that the horizontal position of the laser engraving head 31 can be easily adjusted. When the third motor 28 runs, the third screw 29 will rotate. Since the outer surface of the third screw 29 is threadedly connected to the lifting block 30, when the third screw 29 rotates, it will drive the lifting block 30 to move up and down along the inside of the second slide rail 27. At this time, the laser engraving head 31 will move up and down under the action of the lifting block 30, so that the height of the laser engraving head 31 can be easily adjusted. After the position of the laser engraving head 31 is adjusted, the operator starts the laser engraving head 31, and the laser engraving head 31 can then engrave the product.

[0062] Once the laser engraving head 31 has finished engraving one side of the product, it will send a signal to the built-in controller. At this time, the controller will cause the fourth motor 32 to run. The rotating shaft 20 will drive the gear 21 to rotate. Since the outer surface of the gear 21 is meshed with the outer surface of the gear ring 22, when the gear 21 rotates, it will drive the gear ring 22 to rotate. At this time, the fixed cylinder 17 will rotate inside the top of the base 18 driven by the gear ring 22. At the same time, the fixed cylinder 17 will drive the product to rotate through the top plate 1. When the top plate 1 rotates, its outer surface will release contact with the stop bar 33. When the top plate 1 rotates 180 degrees, the product will be flipped over so that the laser engraving head 31 can engrave the other side of the product. At the same time, the outer surface of the top plate 1 will re-contact the stop bar 33 and be blocked by the stop bar 33, preventing it from rotating further. Due to the design of the stop bar 33, the rotation stroke of the top plate 1 is limited, so that the top plate 1 can only rotate 180 degrees at a time, thereby realizing the function of automatically and accurately flipping the product.
