[0026] Example

[0027] See also Figure 1-6 The present invention provides the following technical solutions: a multi-station turntable laser engraving device, comprising a body 1, a workbench 2 is installed in the middle of the inner cavity of the body 1, a turntable assembly 3 is installed on the top of the workbench 2, a driving assembly 4 and a lifting and positioning assembly 5 are connected inside the turntable assembly 3, the driving assembly 4 is located in the middle of the turntable assembly 3, the lifting and positioning assembly 5 is located on one side of the driving assembly 4, two groups of side assemblies 7 are installed on the top of the turntable assembly 3, and carrier assemblies 6 are installed inside the two groups of side assemblies 7, and products 10 are evenly arranged on the top of the two groups of carrier assemblies 6, an adjustment assembly 8 is installed on one side of the drive assembly 4, and a laser engraving assembly 9 is slidably connected to one side of the adjustment assembly 8, and one end of the laser engraving assembly 9 is located directly above the turntable assembly 3, and the turntable assembly 3 is used to carry the two groups of carrier assemblies 6, and the two groups of carrier assemblies 6 correspond to the two groups of side assemblies 7, The two groups of side assemblies 7 fix the corresponding carrier assemblies 6 on the turntable assembly 3, and the driving assembly 4 is used to drive the turntable assembly 3 to rotate, so that the two groups of carrier assemblies 6 are always displaced below the laser engraving assembly 9. When one group of carrier assemblies 6 moves to directly below the laser engraving assembly 9, the jacking and positioning assembly 5 positions this group of carrier assemblies 6, and the driving assembly 4 stops running. The laser engraving assembly 9 can perform laser engraving operations on the products 10 on this group of carrier assemblies 6, while the other group of carrier assemblies 6 stays at the farthest position from the laser engraving assembly 9 in a straight line. This group of carrier assemblies 6 can be loaded and unloaded by a robot. Conversely, the two groups of carrier assemblies 6 switch positions relative to each other, and the products 10 after laser engraving are moved out, and the products 10 not laser engraved are moved to the bottom of the laser engraving assembly 9 for laser engraving. The adjusting assembly 8 can adjust the height of the laser engraving assembly 9, thereby changing the laser engraving range of the laser engraving assembly 9.

[0028] The turntable assembly 3 includes a base 31 and a supporting frame 32. The base 31 is fixedly connected to one side of the top of the workbench 2. The supporting frame 32 is located directly above the base 31. The driving assembly 4 and the lifting and positioning assembly 5 are both installed between the base 31 and the supporting frame 32. The supporting frame 32 is used to support and position the carrier assembly 6 and the side assembly 7, and the driving assembly 4 is used to support and drive the supporting frame 32 to rotate. There is a certain gap between the base 31 and the supporting frame 32. The lifting and positioning assembly 5 can be installed in this gap and play a positioning role for the supporting frame 32.

[0029] The driving assembly 4 includes a rotating cylinder 41, the output end of the rotating cylinder 41 is connected to a connecting plate 42, and the top of the connecting plate 42 is connected to a plurality of connecting rods 43, and the plurality of connecting rods 43 are all vertically arranged. Connecting holes 44 are evenly opened in the middle of the carrier frame 32, and the plurality of connecting rods 43 are respectively arranged corresponding to the plurality of connecting holes 44, and the top ends of the connecting rods 43 are inserted into the inside of the connecting holes 44. The connecting rods 43 and the connecting holes 44 are plugged in and matched to connect the connecting plate 42 and the carrier frame 32. The rotating cylinder 41 is used to drive the connecting plate 42 and the connecting rods 43 to rotate as a whole, thereby providing power for the rotation of the carrier frame 32.

[0030] The lifting and positioning assembly 5 includes a lifting cylinder 51, which is installed on one side of the top of the base 31. A slide seat 52 is slidably connected to one side of the lifting cylinder 51. Two positioning rods 53 are symmetrically connected to the top of the slide seat 52. The tops of the two positioning rods 53 are provided with tapered portions. Two through grooves 54 are provided at both ends of the bottom of the carrier frame 32. The positioning rods 53 and the through grooves 54 are correspondingly provided. When the carrier frame 32 rotates, the two through grooves 54 provided at the bottom thereof change position. When a through groove 54 moves to the bottom of the laser engraving assembly 9, the rotating cylinder 41 drives the carrier frame 32 to stop rotating. At the same time, the piston rod of the lifting cylinder 51 pushes the slide seat 52 and the two positioning rods 53 to move upward as a whole. The two positioning rods 53 move to the inside of the through grooves 54, thereby preliminarily positioning the carrier frame 32.

[0031] The two groups of carrier components 6 each include a bearing plate 61, the two bearing plates 61 are respectively mounted on the top of the bearing frame 32 and are located above the two through slots 54, a placement frame 62 is mounted on the top of the bearing plate 61, two positioning holes 65 are symmetrically provided on the top of the placement frame 62, the bottom ends of the positioning holes 65 extend to the bottom of the bearing plate 61, bushings 66 are provided inside the two positioning holes 65, grooves 67 are provided on the outer wall of the bushing 66 and the inner wall of the positioning hole 65, the two grooves 67 are connected to each other, a clamp 63 is evenly mounted on the top of the placement frame 62, the product 10 is mounted on the top of the clamp 63, an air pipe 64 is provided on one side of the bearing plate 61, one end of the air pipe 64 is connected to the bottom of the clamp 63, and the clamp 63 is used to carry out product 10 The positioning is performed, and one end of the air pipe 64 is connected to the suction device, which can be a suction pump, which is not specifically limited here. After the product 10 is placed, the suction device extracts the gas in the clamp 63, so that a negative pressure is formed between the product 10 and the clamp 63 to generate suction, thereby fixing the product 10 on the top of the placement rack 62. The carrier frame 32 is used to drive the two groups of carrier components 6 to move, that is, the two carrier plates 61 drive the corresponding placement racks 62, clamps 63 and products 10 to move respectively. When a group of carrier components 6 moves to the bottom of the laser engraving component 9, the lifting cylinder 51 drives the two positioning rods 53 to extend into the through groove 54, and the two positioning rods 53 continue to move upward and are inserted into the corresponding positioning holes 65, thereby accurately positioning the carrier frame 32;

[0032] When the positioning rod 53 is inserted into the positioning hole 65 , the tapered portion provided on the top of the positioning rod 53 prevents the positioning rod 53 from being unable to be inserted into the positioning hole 65 when it is offset, thereby improving the insertion accuracy of the positioning rod 53 and the positioning hole 65 .

[0033] The two groups of side components 7 each include two first clamping blocks 71 and two groups of L-shaped clamping blocks 72. The first clamping blocks 71 and the L-shaped clamping blocks 72 are both located at the top of the carrier frame 32. The multiple L-shaped clamping blocks 72 are respectively located on both sides of the carrier plate 61. The two first clamping blocks 71 are located at the front end and the rear end of the carrier plate 61, and the front end and the rear end of the carrier plate 61 are respectively inserted into the inside of the two first clamping blocks 71. When the carrier assembly 6 is placed on the top of the carrier frame 32, the multiple first clamping blocks 71 clamp and position the two sides of the carrier plate 61, and the two L-shaped clamping blocks 72 clamp the front end and the rear end of the carrier plate 61 respectively. At this time, the carrier plate 61 cannot be displaced in the horizontal direction. Since the carrier plate 61 is inserted into the inner walls of the two L-shaped clamping blocks 72, the carrier plate 61 remains stationary in the vertical direction.

[0034] The adjustment component 8 includes a lifting frame 81, which is installed on the top of the workbench 2. The lifting frame 81 is internally rotatably connected to a rotating rod 82. The top of the rotating rod 82 extends to the top of the lifting frame 81 and is connected to a handle 83. The laser engraving component 9 is threadedly connected to the rotating rod 82. The staff drives the rotating rod 82 to rotate by holding the handle 83, thereby providing power for the laser engraving component 9 to move up and down.

[0035] The laser engraving assembly 9 includes a support frame 91, which is threadedly connected to the rotating rod 82. A laser engraving laser head 92 is installed at one end of the support frame 91. The laser engraving laser head 92 is located directly above the turntable assembly 3. The top of the placement frame 62 is set with range A, range B and range C. Range A is the actual occupied range of the product 10, range B is the optimal laser range, and range C is the maximum laser range. The sizes of range A, range B and range C increase in sequence. The support frame 91 is used to support the laser engraving laser head 92;

[0036] When the product 10 is placed on the top of the carrier assembly 6, the actual occupied range of the product 10 is formed according to the placement range of the product 10. When the driving assembly 4 drives the carrier assembly 6 and the product 10 to rotate and displace, the actual occupied range of the product 10 changes position accordingly. When the product 10 moves to the bottom of the laser engraving laser head 92, the actual occupied range of the product 10 moves to the bottom of the laser engraving laser head 92 synchronously, and the actual occupied range of the product 10 moves to the inside of the range C. The staff adjusts the height of the laser engraving laser head 92 to change the size of the range C. When the size of the range C is adjusted to be consistent with the size of the range B, the laser engraving range of the product 10 is optimal at this time, and the laser engraving laser head 92 performs laser engraving operation on the product 10.

[0037] Specifically, the laser engraving device is connected to the control system, and the staff places two sets of carrier components 6 at the two ends of the top of the carrier frame 32, and fixes the two sets of carrier components 6 through the first clamp block 71 and the L-shaped clamp block 72, and connects the connecting plate 42 and the carrier frame 32 through the connecting rod 43 and the connecting hole 44.

[0038] The control system controls the external manipulator to place the product 10 on a set of carrier components 6. The fixture 63 is used to position the product 10. The actual occupied range of the product 10 is formed according to the placement range of the product 10. When this set of carrier components 6 is fully loaded, the control system controls the rotating cylinder 41 to start. The rotating cylinder 41 drives the connecting plate 42 and the connecting rod 43 to rotate as a whole, and the actual occupied range of the product 10 changes accordingly. When the fully loaded carrier component 6 moves to the bottom of the laser engraving laser head 92, the actual occupied range of the product 10 moves synchronously to the bottom of the laser engraving laser head 92, and the actual occupied range of the product 10 moves to the inside of the maximum laser range of range C, and the rotating cylinder 41 The support frame 32 is driven to stop rotating, and the staff rotates the handle 83 to drive the rotating rod 82 to rotate, thereby adjusting the height of the support frame 91 and the laser engraving laser head 92, thereby changing the size of the maximum laser range of range C. When the size of the maximum laser range of range C is adjusted to be consistent with the size of the optimal laser range of range B, the laser engraving range of the product 10 is optimal at this time. After this adjustment is completed, for the same product 10, there is no need to adjust the height of the laser engraving laser head 92 again when performing laser engraving operations. At the same time, the lifting cylinder 51 drives the two positioning rods 53 to extend into the through groove 54, and the two positioning rods 53 continue to move upward and are inserted into the corresponding positioning holes 65, thereby accurately positioning the support frame 32;

[0039] The laser engraving laser head 92 performs laser engraving on the product 10 on the fully loaded carrier assembly 6. At the same time, the control system controls the external robot to load another carrier assembly 6 that is in an empty state. When the laser engraving of the product 10 on the fully loaded carrier assembly 6 is completed, the control system controls the driving assembly 4 to drive the two groups of carrier assemblies 6 to switch positions, and the laser engraved products 10 are moved out. The control system controls the robot to unload the laser engraved products 10 and re-place new products 10. The un-laser engraved products 10 are moved to the bottom of the laser engraving laser head 92 for laser engraving.

[0040] If multiple sets of laser engraving devices are set up, the same robot can continuously load and unload materials, so that after completing the laser engraving of one set of products 10, the time before the next loading and unloading of the robot can be used to carry out the laser engraving of the next set of products 10.
