[0043] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0045] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0046] The main solution of this application is: based on the cooperation between the laser engraving machine and the laser engraving positioning tooling that can adjust the angle of the product to be processed, the processing angle of the product can be adjusted before laser engraving. At the same time, it can also meet the laser engraving requirements of products in different processing positions at the same processing angle, that is, it can meet the laser engraving requirements of products at different angles and positions. Because the number of laser engraving tooling is reduced, the time for repeated clamping of the product is saved, and the processing cost is reduced.

[0047] The traditional laser engraving method is to place the product on a tooling with a fixed and non-adjustable angle for laser engraving. When the laser engraving structure on a product has multiple angles, multiple sets of tooling are required for laser engraving, and the angle of each set of tooling is fixed and non-adjustable. The laser engraving structures of the products of each project are basically not similar. After processing each project's product, the corresponding laser engraving tooling will be idle and scrapped, resulting in a waste of costs.

[0048] The present invention can drive the product to rotate 360 ​​degrees through the angle adjustment of the motor and the rotation of the motor, thereby meeting various processing requirements of the product.

[0049] It should be noted that the execution subject of this embodiment can be a control system of the line body, or it can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, personal computer, mobile phone, etc. This embodiment does not make specific limitations on this.

[0050] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "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 technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] Specifically, the present invention proposes a laser engraving device, which includes a laser engraving positioning fixture 100, a laser engraving machine and a control component. The laser head of the laser engraving machine is located above the laser engraving positioning fixture 100, and is used to perform laser engraving on the surface of the product to be processed. The control component is electrically connected to the drive structure 22 of the laser engraving positioning fixture 100 and the laser engraving machine. The laser engraving positioning fixture 100 has the function of adjusting the angle and orientation of the product, so that the product can correspond to the laser head with different surfaces to be processed, or the product can correspond to the laser head at different angles, so as to realize flexible adjustment of the product laser engraving.

[0053] For details, please refer to Figure 2The laser engraving positioning tool 100 includes a support frame 1, a rotation drive device 2, a limiting structure and a mounting structure 3. The rotation drive device 2 includes a fixed seat 21 and a driving structure 22 fixed on the fixed seat 21. The fixed seat 21 has a mounting end 21b and a connecting end 21a relative to each other along its length direction. The driving end of the driving structure 22 extends toward the mounting end 21b. The connecting end 21a is rotatably mounted on the support frame 1 around an axis extending in the width direction of the fixed seat 21, so that the mounting end 21b can swing around the connecting end 21a. , thereby driving the driving end of the driving structure 22 to swing; the limiting structure is arranged between the rotation driving device 2 and the support frame 1, so that the rotation driving device 2 can be limited to multiple positions on its swinging trajectory; the mounting structure 3 includes a mounting seat 31 and at least one identification portion 32 arranged on the mounting seat 31, the mounting seat 31 is installed on the driving end of the driving structure 22 to be driven to rotate by the rotation driving device 2, the mounting seat 31 is used for installing the product to be laser engraved, and the identification portion 32 is arranged corresponding to the laser engraving processing surface of the product.

[0054] In the technical solution of the present invention, the connection end 21a of the fixed seat 21 serves as the rotation center, and the mounting end 21b of the fixed seat 21 can slide around the rotation center and along the extension direction of the arc guide rail 12, thereby driving the driving structure 22 on the fixed seat 21 to swing, and realizing the angle adjustment of the driving structure 22. Since the mounting seat 31 is connected to the driving end of the driving structure 22, the product to be processed is driven to adjust synchronously, and the processing angle is adjusted. Based on the rotation driving characteristics of the driving structure 22 itself, it can drive the product to be processed to rotate and realize the adjustment of the processing position, so that different positions of the product in the circumferential direction are rotated to the corresponding position of the laser head, so that multiple processing requirements of the product can be met through one tooling, reducing the number of laser engraving tools. For different products, it is only necessary to replace the mounting seat 31 to realize the common use of products of different projects, and the reuse rate of tooling is high, which reduces the cost.

[0055] The present invention does not limit the specific form of the driving structure 22. In this embodiment, the driving structure 22 is a motor, and its driving end is a motor shaft. In other embodiments, the driving structure 22 can also be in the form of a hydraulic motor, a cylinder and a gear rack matching structure.

[0056] Specifically, the support frame 1 has a mounting wall opposite to the rotation drive device 2, and a curved guide rail 12 is provided on one side end of the mounting wall; the connecting end 21a of the fixed seat 21 is rotatably mounted on the side end of the mounting wall away from the curved guide rail 12, and the mounting end 21b of the fixed seat 21 can slide along the curved guide rail 12. The curved track can be a groove structure or a hole structure, both of which can satisfy the guiding function. The two ends of the curved guide rail 12 correspond to the extreme adjustment angles of the fixed seat 21. In the present embodiment, the adjustment area of ​​the fixed seat 21 is 0 to 90 degrees. In other implementations, 60 degrees, 80 degrees, or 120 degrees can also be set, and the present invention is not limited to this.

[0057] In order to facilitate the precise positioning of the angle during the adjustment of the fixing seat 21, in some implementations, a plurality of scale marks 13 are provided on the surface of the support frame 1, and the plurality of scale marks 13 are located on the side of the arc-shaped guide rail 12 and are arranged at intervals along the extension direction of the arc-shaped guide rail 12. The plurality of scale marks 13 correspond to corresponding angles, and the angles can be indicated on the edges of some of the scale marks 13. In this case, the bottom surface of the support frame 1 can be used as the base surface to facilitate the operator to identify the adjustment position.

[0058] It should be noted that the present invention does not limit the form of the limiting structure, as long as the fixing seat 21 can be fixed to a part of the position on the support frame 1, that is, the swing adjustment of the corresponding fixing seat 21 can be set to be automatic or semi-automatic. For example, the limiting structure may include a connecting rod and a cylinder. Based on the matching form of the two, the specific telescopic stroke of the cylinder rod can drive the mounting end 21b of the fixing seat 21 to move and stay at a specific angle, so that it can automatically slide in the arc guide rail 12 as required. For another example, the arc guide rail 12 is an arc hole opened on the mounting wall, and the limiting structure includes an adjusting bolt 14, and the end of the adjusting bolt 14 passes through the arc hole to be threadedly connected to the mounting end 21b. The operator tightens the adjusting bolt 14, and with the cooperation of the thread and the nut, the fixing seat 21 can be locked on the support frame 1. When the operator rotates the adjusting bolt 14 in the opposite direction, the fixing seat 21 becomes loose, and the fixing seat 21 can be manually pushed to slide. At this time, the adjusting bolt 14 not only serves as a locking member, but also serves as a guide member that cooperates with the waist-shaped hole.

[0059] In other implementations, taking into account positioning cooperation, a sliding protrusion can be set on the side of the fixed seat 21, and the sliding protrusion can be inserted into the arc guide rail 12 as a sliding guide. A rotating shaft can also be set at the end of the fixed seat 21 and inserted into the hole on the support frame 1 as an axis-hole cooperation, thereby serving as a rotational cooperation form between the connecting part and the support frame 1.

[0060] The present invention does not limit the specific form of the support frame 1, which may be a frame structure, an L-shaped structure, a T-shaped structure, etc. In the present embodiment, the support frame 1 includes two support plates 11 arranged opposite to each other, and the two sides of the support plates 11 facing each other are provided with the arc-shaped guide rails 12; the fixing seat 21 is arranged between the two support plates 11. The fixing seat 21 is rotatably connected to the two support plates 11 respectively, and the two support plates 11 form a stable support frame 1. It should be understood that, considering the connection and fixation of the two support plates 11, a plurality of connecting blocks can be provided to connect the two support plates 11. It should be noted that the setting of the connecting blocks cannot hinder the swing of the fixing seat 21.

[0061] Taking into account the coordination between the mounting seat 31 and the driving structure 22, the fixing seat 21 can be set to be L-shaped, that is, it is composed of two plates set at an angle, one of which serves as the mounting end 21b and has a center hole thereon, and the driving structure 22 is horizontally placed on the other plate, and the driving end can extend from the center hole so as to be connected to the middle of the mounting seat 31.

[0062] The shape of the mounting seat 31 is not limited, it only needs to ensure the fixation of the product and coaxial rotation with the motor shaft. In some embodiments, the mounting seat 31 is provided with a profiling portion 31a, which is used to match the product to be processed; the profiling portion 31a can be a profiling groove or a direction convex block, which is used to match the shape of the product and facilitate the fixation of the product. This structural form facilitates the clamping of the product and improves the work efficiency of the operator.

[0063] In some embodiments, the mounting seat 31 is provided with an avoidance groove 31 b ; the avoidance groove 31 b is used to avoid the local structure of the product surface to achieve a better adaptation effect.

[0064] Considering the installation of the product, the mounting seat 31 and the identification portion 32 are staggered along the axial direction of the driving structure 22. That is, although the identification portion 32 is connected to the mounting seat 31, the end surface of the identification portion 32 is not on the same plane as the mounting seat 31, so as to avoid the product.

[0065] In this embodiment, the identification portion 32 is located on the side of the mounting seat 31. It should be understood that when the product has multiple processing positions, multiple identification portions 32 can be set. The multiple identification portions 32 are arranged at intervals along the circumference of the mounting seat 31. The interval between two adjacent identification portions 32 is not limited, and is mainly determined by the processing position on the circumference of the product.

[0066] It should be noted that after the logo portion 32 is blackened, the laser engraving machine can perform sensing and recognition. When the logo portion 32 is recognized, the program can control the driving structure 22 to pause and the laser engraving machine performs laser engraving.

[0067] In one embodiment of the present invention, the processing sequence of the laser engraving equipment is as follows:

[0068] The driving structure 22 is a motor, which is fixed on the motor fixing seat 21. The connecting end 21a of the fixing seat 21 is connected to the two support plates 11 through a rotating shaft, and the mounting end 21b is fixed in two arc-shaped holes through two adjusting bolts 14, so that the fixing seat 21 can drive the motor to rotate around the rotating shaft through the adjusting bolts 14 on both sides, and can also adjust the fixed angle on the support plate 11. The mounting seat 31 is fixed on the driving end of the motor, that is, the output shaft of the motor, and the identification part 32 is fixed on the mounting seat 31. The mounting seat 31 and the identification part 32 can move with the rotation of the motor. After the identification part 32 is blackened, the laser engraving machine can perform induction recognition. When this identification part 32 is recognized, the program can control the motor to pause, and the laser engraving machine performs laser engraving. After the laser engraving is completed, the motor drives the product to rotate to the initial position where the product is placed, and the operator removes the laser engraved product. At this time, a basic semi-automatic laser engraving process is completed.

[0069] The laser engraving equipment can be fully automatic or semi-automatic, and can realize the functions of multiple sets of traditional laser engraving tools, reducing the number of laser engraving tools and reducing tooling costs. Laser engraving of different project products only requires replacing the mounting seat 31 or adjusting the number and position of the identification part 32, with a high reuse rate, reducing idle waste of tools.

[0070] Reference below Figure 3 , which shows a schematic diagram of the structure of the control component suitable for implementing the embodiment of the present application. The control component in the embodiment of the present application may include but is not limited to mobile terminals such as mobile phones, laptop computers, digital broadcast receivers, PDAs (Personal Digital Assistants), PADs (Portable Application Descriptions), PMPs (Portable Media Players), vehicle-mounted terminals (such as vehicle-mounted navigation terminals), etc., and fixed terminals such as digital TVs, desktop computers, etc. Figure 3 The control component shown is only an example and should not bring any limitation to the functions and scope of use of the embodiments of the present application.

[0071] like Figure 3As shown, the control component may include a processing device 1001 (e.g., a central processing unit, a graphics processor, etc.), which can perform various appropriate actions and processes according to a program stored in a read-only memory (ROM) or a program loaded from a storage device 1003 to a random access memory (RAM). In RAM 1004, various programs and data required for the operation of the control component are also stored. The processing device 1001, ROM 1002, and RAM 1004 are connected to each other via a bus 1005. An input / output (I / O) interface 1006 is also connected to the bus. Generally, the following systems can be connected to the I / O interface 1006: an input device 1007 including, for example, a touch screen, a touch pad, a keyboard, a mouse, an image sensor, a microphone, an accelerometer, a gyroscope, etc.; an output device 1008 including, for example, a liquid crystal display (LCD: Liquid Crystal Display), a speaker, a vibrator, etc.; a storage device 1003 including, for example, a magnetic tape, a hard disk, etc.; and a communication device 1009. The communication device 1009 can allow the control component to communicate with other devices wirelessly or wired to exchange data. Although the control component with various systems is shown in the figure, it should be understood that it is not required to implement or have all the systems shown. More or fewer systems can be implemented or have alternatively.

[0072] In particular, according to the embodiment disclosed in the present application, the process described above with reference to the flowchart can be implemented as a laser engraving program. The laser engraving program contains program code for executing the method shown in the flowchart. In such an embodiment, the laser engraving program can be downloaded and installed from the network through a communication device, or installed from the storage device 1003, or installed from the ROM 1002. When the laser engraving program is executed by the processing device 1001, the above functions defined in the method of the embodiment disclosed in the present application are executed.

[0073] Based on the above laser engraving equipment, please refer to Figure 1 The present invention proposes a laser engraving method, which specifically includes the following steps:

[0074] S10: After the fixing seat 21 of the rotation driving device 2 swings to a set angle, the initial position of the product to be laser engraved on the laser engraving positioning tool 100 is obtained;

[0075] It should be understood that the swing adjustment of the fixing seat 21 is different according to the design of the laser engraving positioning tool 100. When the fixing seat 21 is electrically adjusted, a control component may drive the corresponding structure to automatically adjust according to the processing parameters; when the fixing seat 21 is adjusted by adjusting the bolt 14 and the arc hole, the operator manually adjusts it in advance according to the process requirements.

[0076] The initial position can be obtained by taking one of the identification parts 32 as a reference, and taking the position of the identification part 32 as the initial position of the product. The initial position can be used as the basic coordinate point for the subsequent rotation of the driving structure 22, and can also facilitate resetting after the laser engraving process is completed.

[0077] S20: Control the driving end of the driving structure 22 to rotate so that the corresponding identification portion 32 is located at the laser engraving processing position, and control the laser engraving machine to work to perform laser engraving on the laser engraving processing surface of the product to be laser engraved;

[0078] It should be understood that at this time, the angle of the fixing seat 21 is fixed, and the mounting seat 31 and the product rotate under the drive of the driving structure 22, thereby changing the position. Each of the identification parts 32 corresponds to a laser engraving processing surface of the product. Therefore, when the identification part 32 rotates to the laser engraving processing position, it is in the recognition area of ​​the laser engraving machine and can be recognized by the laser engraving machine, thereby facilitating the positioning of the laser engraving machine for laser engraving.

[0079] It should be understood that the laser engraving machine can identify the identification portion 32, so its laser engraving path is planned according to the initial distance value between the identification portion 32 and the product after installation.

[0080] In the technical solution of the present invention, before laser engraving, the swing angle of the fixed seat 21 is adjusted, so as to drive the driving structure 22 and the mounting seat 31 to adjust synchronously, so that the angle between the product on the mounting seat 31 and the laser head or the horizontal plane can meet the laser engraving processing requirements of the product. After the angle adjustment of the fixed seat 21 is completed, the initial position of the product at this time is obtained to facilitate the positioning of subsequent processing and the reset after the processing is completed. Then, the driving end of the driving structure 22 is controlled to drive the product to rotate, so that the corresponding identification part 32 corresponds to the laser head, so that it can be recognized by the laser head. At this time, the laser engraving machine is controlled to work to perform laser engraving on the laser engraving processing surface of the product. This processing method can adapt to multiple processing angles of the product, and can process multiple laser engraving processing surfaces of the product at the same time. The process steps are more concise. After the fixed seat 21 swings to the set angle, no manual intervention is required until the product processing is completed.

[0081] It should be noted that there is a set corresponding relationship between the set angle and the product to be laser engraved. This is determined by the processing requirements of the product, that is, the laser engraving process of each product has specific processing angle and processing position requirements. The set angle is the set angle of the current processed product. The set angle of different products may be different. The set angle can be the angle between the fixed seat 21 and the horizontal plane, or the angle between the plane where the fixed seat 21 is located and the straight line where the laser emitted by the laser head is located. The present invention is not limited to this.

[0082] For example, product A requires one laser engraving surface to be processed at a first angle and another laser engraving surface to be processed at a second angle. At this time, the process flow of product A should be to first determine the set angle according to the first angle to adjust the rotation drive device 2, and then make the identification part 32 in the laser engraving processing position during the rotation drive of the drive structure 22, and reset the mounting seat 31 after the laser engraving processing is completed. The product does not need to be removed, and the new set angle is determined at the second angle to re-adjust the rotation drive device 2, and then repeat step S20 until the processing is completed.

[0083] The above-mentioned laser engraving processing position refers to the position when the laser engraving processing surface of the product is exactly corresponding to the laser beam of the laser head. Taking the laser head being located directly above the laser engraving positioning fixture 100 as an example, the position where the downward projection of the laser head falls on the laser engraving positioning fixture 100 is the laser engraving processing position. Each time the product rotates to the laser engraving processing position, the identification part 32 can be recognized by the laser engraving machine, and the laser engraving processing surface can be directly opposite to the laser head.

[0084] Furthermore, after step S20, the method further includes:

[0085] The driving end of the driving structure 22 is controlled to continue rotating so that the product is reset to the initial position.

[0086] It should be noted that the processing procedure of the equipment is pre-designed, so it should be ensured that each product is in the same position after installation to ensure the accuracy of the entire laser engraving process.

[0087] Further, when there are multiple identification parts 32, the multiple identification parts 32 are arranged along the circumference of the mounting seat 31. In this case, step S20 includes:

[0088] S21: Control the driving end of the driving structure 22 to rotate so that the multiple identification parts 32 arrive at the laser engraving processing position in sequence, and correspondingly control the laser engraving machine to perform laser engraving operations on the product and the multiple laser engraving processing surfaces corresponding to the multiple identification parts 32 in sequence.

[0089] That is, according to the processing technology of the product, the multiple identification parts 32 have a certain processing sequence, so in actual processing, the multiple identification parts 32 need to be arranged in a certain order to arrive at the laser engraving processing position in sequence. This is because although the multiple identification parts 32 can be recognized by the laser engraving machine after blackening, the laser engraving machine cannot recognize the accuracy of the identification parts 32. Therefore, it is necessary to control the rotation driving angle of the driving structure 22 to control the timing of the multiple identification parts 32 staying at the laser engraving processing position.

[0090] For example, the processing order of the laser engraving processing surfaces corresponding to the multiple identification parts 32 is arranged in the clockwise direction along the driving structure 22. When the driving structure 22 is driven clockwise, each time an identification part 32 reaches the laser engraving processing position and is recognized by the laser engraving machine, the driving structure 22 stops rotating. After the laser engraving processing is completed, it continues to rotate until the second identification part 32 reaches the laser engraving processing position, and so on to complete the processing.

[0091] In another case, the processing order of the laser engraving processing surface corresponding to the multiple identification parts 32 is not arranged in the clockwise direction of the driving structure 22. The laser engraving process is described by taking three identification parts 32 as an example:

[0092] The multiple identification parts 32 include a first identification part, a second identification part and a third identification part distributed along the rotation direction of the mounting seat 31, and there are multiple corresponding laser engraving processing surfaces on the product surface, namely the first laser engraving processing surface, the second laser engraving processing surface, and the third laser engraving processing surface. The laser engraving operation order is the first laser engraving processing surface, the third laser engraving processing surface and the second laser engraving processing surface.

[0093] Step S21 includes:

[0094] S211: controlling the driving end of the driving structure 22 to rotate so that the first marking portion reaches the laser engraving processing position, and controlling the laser engraving machine to perform a first laser engraving operation on the first laser engraving processing surface;

[0095] S212: After the first laser engraving operation is completed, the driving end of the driving structure 22 is controlled to continue to rotate, driving the second marking portion to pass through the laser engraving processing position, so that the third marking portion reaches the laser engraving processing position, and the laser engraving machine is controlled to perform a second laser engraving operation on the third laser engraving processing surface;

[0096] S213: After the second laser engraving operation is completed, the driving end of the driving structure 22 is controlled to continue to rotate so that the second marking portion reaches the laser engraving processing position, and the laser engraving machine is controlled to perform a third laser engraving operation on the second laser engraving processing surface.

[0097] It should be noted that the processing premise of the laser engraving machine should be that the driving structure 22 rotates to meet the first angle condition and the laser engraving machine recognizes an identification portion 32. The laser engraving machine will not start working when only one of the conditions is met, so that when the laser engraving operation sequence is the first laser engraving processing surface, the third laser engraving processing surface and the second laser engraving processing surface, the laser engraving machine can still process in the correct order.

[0098] It should be noted that after the laser engraving machine completes the laser engraving work, it will send out a signal, and the control component controls the driving structure 22 to drive the product to reset according to the signal.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
