[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] The present invention provides a laser engraving device, referring to Figure 1 and Figure 2 The laser engraving equipment includes two processing devices 1, a conveying device 2 and a flipping device 3. The two processing devices 1 are arranged side by side and are both provided with a processing station 14. Each processing device 1 is used to perform laser engraving on the surface of the processed product. The conveying device 2 is arranged across the two processing stations 14 and is used to transport the processed product between the two processing stations 14.

[0029] The conveying device 2 has a turning station 21 . The turning device 3 is disposed between the two processing stations 14 and is disposed corresponding to the turning station 21 . The turning device 3 is used to turn over the processed products on the conveying device 2 .

[0030] Based on the above-mentioned scheme setting, different surfaces of the processed product can be processed through two processing devices 1, a flipping device 3 and a conveying device 2. On the one hand, it is not only compatible with different products, so that the front and back sides of different products can be laser processed, but also can realize automatic processing, which greatly reduces labor costs, thereby improving the production efficiency of engraving the surface of processed products.

[0031] In actual use, when it is necessary to perform laser processing on the front and back sides of the processed product, double-sided processing can be achieved through the flipping device 3 and the two processing devices 1; when only a single side of the processed product needs to be processed, single-sided processing can be completed through only two processing devices 1 and the conveying device 2; this arrangement can improve the equipment utilization rate of the laser engraving equipment.

[0032] Reference Figures 2 to 6 The conveying device 2 includes a processing conveyor line 22, a return conveyor line 23 and a conveying jig 24. The return conveyor line 23 and the processing conveyor line 22 are arranged at intervals in the vertical direction. The return conveyor line 23 is arranged below the processing conveyor line 22. The conveying direction of the processing conveyor line 22 is opposite to the conveying direction of the return conveyor line 23. The processing conveyor line 22 is used to convey the conveying jig 24 carrying the processed products, and the return conveyor line 23 is used to convey the conveying jig 24 carrying empty materials.

[0033] By adopting the upper and lower layer conveying method, on the one hand, it can not only reasonably utilize the space and reduce the occupied space of the structure, but also on the other hand, it can effectively avoid manual running back and forth to load and unload materials, greatly reducing labor costs, thereby improving the efficiency of loading and unloading materials and improving the production efficiency of the laser engraving equipment.

[0034] Specifically, the processing conveyor line 22 and the return conveyor line 23 can be double-belt conveyors, that is, the middle area of ​​the processing conveyor line 22 and the return conveyor line 23 is hollow, so that it is convenient to place the lifting component 12 of the processing device 1, the lifting component 33 of the turning device 3 and other structures, so as to reasonably use the space and improve the space utilization rate.

[0035] The conveying jig 24 has a plurality of discharge holes 242 extending through the thickness direction thereof, and the plurality of discharge holes 242 are arranged in a matrix, and the discharge holes 242 are provided for placing the processed products. The processed products may be small parts processed products, such as small magnets. The conveying jig 24 is provided in a plate shape, and the material of the conveying jig 24 is made of wood, so that it can be used continuously in the laser processing environment, and the production is reliable, which helps to improve the safety and reliability of the production.

[0036] Reference Figures 2 to 6 The processing device 1 includes a machine table 11, a lifting component 12 and a laser processing component 13. The machine table 11 has a mounting surface 111. The lifting component 12 and the laser processing component 13 are both mounted on the mounting surface 111. The lifting component 12 is arranged at a processing station 14. The lifting component 12 is used to lift or lower the processed product on the conveying device 2. The laser processing component 13 is used to perform laser engraving on the processed product.

[0037] The return conveyor line 23 is fixed on the mounting surface 111 by means of a mounting bracket, and the processing conveyor line 22 can also be fixed on the return conveyor line 23 by means of a mounting bracket, so that the return conveyor line 23 and the processing conveyor line 22 are arranged in upper and lower layers. The lifting assembly 12 is installed on the processing conveyor line 22 and is located in the middle area of ​​the processing conveyor line 22.

[0038] The lifting component 12 and the laser processing component 13 can be used to automatically lift and lower the conveying fixture 24, so that the laser processing component 13 can laser engrave the processed products on the conveying fixture 24, thereby realizing automated processing and improving production efficiency.

[0039] The lifting assembly 12 includes a first stopper 121 and a lifting member 122. The first stopper 121 is provided with a first telescopic end 1211. The conveying device 2 includes a conveying jig 24. The conveying jig 24 is used to place the processed products. When the first telescopic end 1211 is in an extended state, the conveying jig 24 is stopped so that the conveying jig 24 rests on the processing station 14. When the first telescopic end 1211 is in a contracted state, the conveying jig 24 is released. The lifting member 122 is used to lift, support or lower the conveying jig 24 resting on the processing station 14.

[0040] Among them, the first stop member 121 and the lifting member 122 can be fixedly installed on the supporting structure of the processing conveyor line 22 through the foot plate, the foot plate is set across the processing conveyor line 22, and the first stop member 121 and the lifting member 122 are both located under the belt plane of the supporting conveying fixture 24 of the processing conveyor line 22.

[0041] The first stopper 121 and the lifting member 122 can both be cylinders, and the first telescopic end 1211 is formed on the piston rod of the first stopper 121. When the conveying jig 24 moves to the processing station 14, the first stopper 121 drives the piston rod to extend to stop the conveying jig 24 on the processing station 14, and the piston rod of the lifting member 122 is connected to a lifting plate, and the lifting member 122 supports the conveying jig 24 through the lifting plate to lift it, so that the conveying jig 24 is separated from the processing conveyor line 22, and then the laser processing assembly 13 performs laser laser engraving on the processed product.

[0042] The first telescopic end 1211 has a first stopper 1211a, and the conveying jig 24 has a stopper groove 241. The first stopper 1211a and the stopper groove 241 are matched for stopping, and the first stopper 1211a and the groove wall of the stopper groove 241 are in plane contact or curved contact. In this way, the conveying jig 24 can be easily stopped on the processing station 14, and the operation is simple, convenient, effective and reliable.

[0043] For example, when the first stop portion 1211a is set as a stop surface, the bottom of the stop groove 241 is set as a plane, so that the conveying jig 24 can be stably restricted on the processing station 14 through surface contact, thereby improving the stability and reliability of stopping the conveying jig 24; when the first stop portion 1211a is set as a curved surface, the bottom of the stop groove 241 is set as a curved surface, so that the conveying jig 24 can be quickly constrained, thereby improving the efficiency of the first stop member 121 in stopping the conveying jig 24.

[0044] In this embodiment, when the first stop portion 1211a can be set as a stop surface, the bottom of the stop groove 241 can be set as a plane. This is only an example and does not limit the first stop portion 1211a and the bottom of the stop groove 241.

[0045] Continue to refer to Figures 2 to 6 The lifting assembly 12 also includes a second stopper 123, which is spaced apart from the first stopper 121. The lifting member 122 is disposed between the second stopper 123 and the first stopper 121. The second stopper 123 has a mating side 1231 and a stopping side 1232. The mating side 1231 and the first stopper 121 jointly limit the conveying jig 24. The stopping side 1232 is formed with a second stop portion 1232a, and the second stop portion 1232a is used to stop the conveying jig 24 moving along the processing station 14 on the conveying device 2.

[0046] It can be understood that both ends of the conveying jig 24 are provided with a stop groove 241. The second stopper 123 has a second telescopic end, a mating side 1231 is formed on the side of the second telescopic end facing the first stopper 121, and a stop side 1232 is formed on the side of the second telescopic end facing away from the first stopper 121. The second telescopic end extends into the stop groove 241 of the conveying jig 24 away from the first stopper 121, specifically, the mating side 1231 is located in the stop groove 241, and the stop side 1232 at least partially extends out of the stop groove 241.

[0047] With such arrangement, the conveying jig 24 moving along the processing station 14 on the conveying device 2 can be stopped by the second stopper 123, so as to avoid the conveying jig 24 moving along the processing station 14 from colliding with the conveying jig 24 located on the processing station 14, so that the lifting assembly 12 can smoothly lift the conveying jig 24, and the laser processing assembly 13 can process the processed product.

[0048] Continue to refer to Figures 2 to 6 The lifting assembly 12 also includes a first position detection component 124, which is electrically connected to the external control system. The first position detection component 124 is arranged close to the first stop component 121. The first position detection component 124 is used to detect whether the conveying fixture 24 is located at the processing station 14. When the first position detection component 124 detects that the conveying fixture 24 is located at the processing station 14, the first position detection component 124 sends a first in-position signal to the external control system, and the external control system controls the first stop component 121 to stop the conveying fixture 24 based on the first in-position signal.

[0049] Such an arrangement enables the conveying jig 24 to be stopped accurately, so that the processed product carried by the conveying jig 24 can be accurately parked on the processing station 14, thereby improving the processing accuracy of the processed product.

[0050] The lifting assembly 12 also includes a second position detection component 125, which is electrically connected to the external control system. The second position detection component 125 is arranged close to the second stop component 123. The second position detection component 125 is used to detect the position of the conveying fixture 24 moving along the processing station 14 on the conveying device 2. When the conveying fixture 24 moving along the processing station 14 on the conveying device 2 approaches the processing station 14, the second position detection component 125 sends a second in-position signal to the external control system, and the external control system controls the second stop component 123 to stop the conveying fixture 24 based on the second in-position signal.

[0051] Such an arrangement can accurately stop the conveying jig 24 on the conveying device 2 moving along the processing station 14, effectively avoiding the conveying jig 24 moving along the processing station 14 from colliding with the conveying jig 24 located on the processing station 14, thereby improving the processing safety and reliability of the laser engraving equipment.

[0052] The first position detection element 124 and the second position detection element 125 may both be photoelectric sensors, infrared laser sensors, and the like.

[0053] Continue to refer to Figures 2 to 6 The laser processing assembly 13 includes a lifting module 131 and a laser generator 132. The lifting module 131 is installed on the mounting surface 111. The laser generator 132 is connected to the lifting module 131. The lifting module 131 is used to drive the laser generator 132 to approach or move away from the processed product to adjust the focus of the laser generator 132.

[0054] With such an arrangement, the laser generator 132 emits laser light to perform laser engraving on the surface of the processed product, thereby realizing automated engraving processing and improving production efficiency.

[0055] The lifting module 131 can be a screw structure or a linear motor, etc. In the embodiment of the present application, the lifting module 131 is set as a screw structure, and the screw structure includes a support frame, a screw, a slider and a hand wheel. The support frame is mounted on the mounting surface 111, the screw is rotatably arranged in the support frame, the slider is threadedly sleeved on the screw, and the slider is also fixedly connected to the laser generator 132. The hand wheel is fixedly connected to the screw, and the hand wheel can be used to operate the screw to rotate, thereby driving the screw to rotate, and then driving the slider to move, so as to drive the laser generator 132 to rise and fall.

[0056] Such arrangement has a simple structure, and the laser generator 132 can be moved manually, which has a low production cost. Moreover, it does not need to be adjusted many times after being fixed, which is more advantageous in reducing the operating cost.

[0057] Reference Figure 1The processing device 1 includes a protective cover 4, which is arranged on the machine table 11. The two sides of the protective cover 4 are respectively provided with openings, and the two openings are used for the conveying device 2 to pass through. In this way, the protective cover 4 can form a processing space, so that the laser can be confined in the processing space during the processing, thereby protecting the operator, so that the processing can be performed more safely, thereby improving the performance of the laser generator 132.

[0058] The protective cover 4 is provided with an observation window 41 , through which the operator can see the processing status of the processed product in the protective cover 4 , so that the operator can understand the processing progress, thereby increasing the performance of the laser engraving equipment.

[0059] Reference Figures 2 to 6 The conveying device 2 includes a conveying fixture 24, which is used to place the processed product; the flipping device 3 includes a flipping assembly 31, a blocking assembly 32 and a lifting assembly 33. The blocking assembly 32 is used to limit the conveying fixture 24 on the flipping station 21, and the lifting assembly 33 is used to lift or lower the conveying fixture 24 parked on the flipping station 21. When the lifting assembly 33 lifts the conveying fixture 24, the flipping assembly 31 clamps and flips the conveying fixture 24, so that the conveying fixture 24 is turned over.

[0060] When the conveying jig 24 is flipped, the blocking component 32 first blocks the processed product on one side so that the processed product stops on the flipping station 21, and then the lifting component 33 lifts the conveying jig 24 until it is lifted to the flipping component 31. The flipping component 31 clamps the conveying jig 24 and flips the conveying jig 24 to flip the processed product.

[0061] It can be understood that the processed product is placed in the discharge hole 242, and the end faces of both ends of the processed product can be exposed to the outside, which is convenient for processing.

[0062] Specifically, the blocking assembly 32 includes a first blocking cylinder 321 and a second blocking cylinder 322 which are arranged at intervals. The first blocking cylinder 321 and the second blocking cylinder 322 can be fixedly installed on the supporting structure of the processing conveyor line 22 through a foot plate. The foot plate is arranged across the processing conveyor line 22. The first blocking cylinder 321 and the second blocking cylinder 322 are both located under the belt plane of the supporting conveying fixture 24 of the processing conveyor line 22.

[0063] When the conveying jig 24 moves to the flipping station 21, the first blocking cylinder 321 drives the piston rod to extend, and after the piston rod of the first blocking cylinder 321 is extended, the conveying jig 24 is stopped on the flipping station 21, so that the conveying jig 24 is parked on the flipping station 21. The second blocking cylinder 322 drives the piston rod to extend, and after the piston rod of the second blocking cylinder 322 is extended, the conveying jig 24 is stopped at a position close to the flipping station 21, so as to avoid collision between the conveying jigs 24.

[0064] The lifting assembly 33 includes a lifting cylinder 331 and a support plate 332. The lifting cylinder 331 is fixedly mounted on the support structure of the processing conveyor line 22 through a foot plate, and the foot plate is arranged across the processing conveyor line 22. The support plate 332 is connected to the piston rod of the lifting cylinder 331. The lifting cylinder 331 lifts the conveying fixture 24 through the support plate 332, so that the conveying fixture 24 is separated from the processing conveyor line 22 and moved to the flip assembly 31.

[0065] Continue to refer to Figures 2 to 6 The flip assembly 31 includes a bracket 311, a flip driving member 312 and a clamping member 313. The bracket 311 is arranged on either of the two processing devices 1. The flip driving member 312 is installed on the end of the bracket 311 away from the processing device 1. The clamping member 313 is connected to the flip driving member 312. The clamping member 313 is used to clamp or release the conveying fixture 24. The flip driving member 312 is used to drive the clamping member 313 to rotate.

[0066] Such an arrangement can realize driving the conveying fixture 24 to flip so that the unprocessed surface of the processed product faces the laser processing component 13, thereby facilitating laser engraving of the processed product.

[0067] The flip driving member 312 may be a rotary cylinder or a stepping motor.

[0068] The clamping member 313 includes a pneumatic body 3131 and two clamping bodies 3132. The two clamping bodies 3132 are both transmission connected to the pneumatic body 3131. The pneumatic body 3131 is used to drive the two clamping bodies 3132 to open or close. The two clamping bodies 3132 are formed with clamping limit grooves 3133 facing the opposite side. The clamping limit grooves 3133 are used to clamp and limit the conveying fixture 24.

[0069] Such an arrangement can effectively prevent the conveying jig 24 from falling, thereby improving the reliability of the flipping conveying jig 24, improving the efficiency of flipping processed products, and improving production efficiency.

[0070] The conveying device 2 also includes a third position detection component 5 electrically connected to the external control system. The third position detection component 5 is arranged near the first blocking cylinder 321. The third position detection component 5 is arranged at the flipping station 21. The third position detection component 5 is used to detect whether the conveying jig 24 is located at the flipping station 21. When the third position detection component 5 detects that the conveying jig 24 is located at the flipping station 21, the third position detection component 5 sends a third in-position signal to the external control system. The external control system controls the blocking component 32 to block the conveying jig 24 based on the third in-position signal to limit the conveying jig 24 to the flipping station 21, and controls the lifting component 33 to lift the conveying jig 24, and also controls the flipping component 31 to drive the conveying jig 24 to flip.

[0071] Such an arrangement enables the conveying jig 24 to be stopped accurately, so that the processed product carried by the conveying jig 24 can be accurately parked on the flipping station 21 .

[0072] The conveying device 2 also includes a fourth position detection component 6 electrically connected to the external control system. The fourth position detection component 6 is arranged close to the second blocking cylinder 322. The fourth position detection component 6 is used to detect the position of the conveying jig 24 moving along the flipping station 21 on the conveying device 2. When the conveying jig 24 moving along the flipping station 21 on the conveying device 2 approaches the flipping station 21, the fourth position detection component 6 sends a fourth in-position signal to the external control system, and the external control system controls the second blocking cylinder 322 to block the conveying jig 24 based on the fourth in-position signal.

[0073] Such a configuration can accurately block the conveying jig 24 on the conveying device 2 that moves along the flipping station 21, effectively avoiding the conveying jig 24 that moves along the flipping station 21 from colliding with the conveying jig 24 located on the flipping station 21, thereby improving the processing safety and reliability of the laser engraving equipment.

[0074] The third position detection component 5 and the fourth position detection component 6 can both be photoelectric sensors, infrared laser sensors, etc.
