[0061] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0063] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0064] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0065] It should be understood that the term "and / or" as used in this application specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0066] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0067] This application provides an error-assisted correction device and a laser processing equipment to solve the technical problem of low error correction efficiency in laser processing equipment.

[0068] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, the error auxiliary correction device 100 includes a mounting base 1, a cantilever 2, and a clamping assembly 3. The cantilever 2 is rotatably mounted on the mounting base 1. The clamping assembly 3 is rotatably mounted at the end of the cantilever 2 away from the mounting base 1. The rotation center line of the cantilever 2 is parallel to a first direction, and both the rotation center line of the clamping assembly 3 and the length direction of the cantilever 2 are parallel to a second direction. The second direction is perpendicular to the first direction.

[0069] like Figures 1 to 3 As shown, the error-aided correction device 100 of this embodiment can be applied to laser processing equipment. The mounting base 1 is generally disposed on the inner side of the bed 300 of the laser processing equipment so that the first direction is parallel to the vertical direction and the second direction is parallel to the horizontal plane. Understandably, since the cantilever 2 can rotate around the first direction, the second direction changes continuously with the rotation of the cantilever 2.

[0070] For ease of explanation, the following explanation will use the example of the first direction being parallel to the vertical direction.

[0071] like Figures 1 to 3 As shown, when the cantilever 2 rotates to be in contact with the inner side of the bed 300, that is, when the length direction of the cantilever 2 is parallel to the length direction of the bed 300, the cantilever 2 can avoid the laser processing area of ​​the laser processing equipment, thereby preventing the cantilever 2 from interfering with the laser processing equipment's processing of the workpiece. When the cantilever 2 rotates into the laser processing area of ​​the laser processing equipment, that is, when the length direction of the cantilever 2 is perpendicular to the length direction of the bed 300, the clamping assembly 3 can assist in detecting the processing error of the laser processing equipment, thereby enabling the error auxiliary correction device 100 to assist in correcting the error of the laser processing equipment.

[0072] When using the error auxiliary correction device 100, first fix the mounting base 1 to the inside of the bed 300, and then fix the template workpiece to the clamping assembly 3. Then rotate the cantilever 2 so that the cantilever 2 drives the clamping assembly 3 to rotate to the laser processing area of ​​the laser processing equipment. Then rotate the clamping assembly 3 so that the template workpiece is placed horizontally, and then control the laser beam to process the template workpiece in a "U" shaped path. Then rotate the clamping assembly 3 again so that the template workpiece is placed vertically, and then control the laser beam to process the template workpiece again in a "U" shaped path. Then analyze the dimensions of the "U" shaped paths obtained from the two processing to determine the magnitude of the processing error of the laser processing equipment, and then correct the processing error of the laser processing equipment based on the obtained processing error.

[0073] In this embodiment, the cantilever 2 is rotatably mounted on the mounting base 1 so that when the cantilever 2 rotates to be in contact with the bed 300, the cantilever 2 can avoid the laser processing area of ​​the laser processing equipment; when the cantilever 2 rotates to the laser processing area of ​​the laser processing equipment, the laser processing equipment can perform laser processing on the template workpiece held by the clamping assembly 3; by rotating the clamping assembly 3, the laser processing equipment can perform laser processing on the template workpiece at different rotation angles multiple times, so as to perform data analysis on different processing trajectories on the template workpiece, determine the magnitude of the processing error of the laser processing equipment, thereby assisting in correcting the error of the laser processing equipment and improving the efficiency of correcting the processing error of the laser processing equipment.

[0074] In one embodiment, such as Figure 3 As shown, the error auxiliary correction device 100 also includes a first fixed base 4 and a rotating bearing 5. The first fixed base 4 is disposed on the mounting base 1; the cantilever 2 is rotatably disposed on the first fixed base 4 via the rotating bearing 5. This simplifies the structure in which the cantilever 2 is rotatably connected to the first fixed base 4 and also improves the rotational stability of the cantilever 2. The first fixed base 4 can be a plate-like structure.

[0075] In one embodiment, such as Figures 3 to 5 As shown, the error auxiliary correction device 100 further includes a second fixed seat 6, a third fixed seat 7, and a fixed shaft 8. Both the second fixed seat 6 and the third fixed seat 7 are mounted on the mounting base 1. The second fixed seat 6 has a first fixed position 61, and the first fixed seat 6 has a mounting hole 41. The third fixed seat 7 has a second fixed position 71, and the second fixed position 71 and the first fixed position 61 are located on opposite sides of the first fixed seat 4 along a first direction. The fixed shaft 8 is rotatably mounted on the rotating bearing 5, and passes through the mounting hole 41 along the first direction. Both ends of the fixed shaft 8 are respectively located at the first fixed position 61 and the second fixed position 71. The cantilever 2 is mounted on the rotating bearing 5.

[0076] The two ends of the fixed shaft 8 are respectively located at the first fixed position 61 and the second fixed position 71, so that the two ends of the fixed shaft 8 are respectively fixed to the second fixed seat 6 and the third fixed seat 7. The second fixed seat 6 and the third fixed seat 7 are both located on the mounting base 1, thus allowing the fixed shaft 8 to be fixed relative to the mounting base 1. The first fixed seat 4 is provided with a mounting hole 41 for the fixed shaft 8 to pass through, thereby fixing the two ends of the fixed shaft 8 to the second fixed seat 6 and the third fixed seat 7 respectively. The fixed shaft 8 is rotatably mounted on the rotary bearing 5, and the cantilever 2 is mounted on the rotary bearing 5. Therefore, the cantilever 2 can be rotatably mounted on the fixed shaft 8 through the rotary bearing 5, so that the cantilever 2 can rotate relative to the mounting base 1.

[0077] In one embodiment, such as Figure 3 and Figure 4 As shown, both the first fixing position 61 and the second fixing position 71 can be threaded holes, and the end of the fixing shaft 8 can be fixed to the first fixing position 61 or the second fixing position 71 by screws.

[0078] In one embodiment, such as Figure 4 As shown, the second fixing seat 6 and the third fixing seat 7 can be installed as a single unit.

[0079] In one embodiment, such as Figure 2 and Figure 3 As shown, the error auxiliary correction device 100 also includes a housing 60, which is disposed on the mounting base 1 and / or the first fixed base 4. The second fixed base 6, the third fixed base 7 and the rotating bearing 5 are all disposed inside the housing 60, so as to protect the rotating bearing 5 through the housing 60 and prevent foreign objects from entering the rotating bearing 5 and reducing the service life of the rotating bearing 5.

[0080] In one embodiment, such as Figure 3 and Figure 4 As shown, the rotary bearing 5 is located on the side of the first fixed seat 4 near the first fixed position 61, or the rotary bearing 5 is located on the side of the first fixed seat 4 near the second fixed position 71. This simplifies the connection structure between the cantilever 2 and the rotary bearing 5, and avoids interference from the hole wall of the mounting hole 41 on the connection of the cantilever 2 to the rotary bearing 5.

[0081] In one embodiment, such as Figures 1 to 4 As shown, the error auxiliary correction device 100 also includes a first limiting unit 9 and a second limiting unit 10, both of which are disposed on the first fixed base 4. The first limiting unit 9 is used to limit the cantilever 2 to the test position, and the second limiting unit 10 is used to limit the cantilever 2 to the storage position. The cantilever 2 can rotate between the test position and the storage position.

[0082] The first limiting unit 9 limits the cantilever 2 to the test position, so that the clamping component 3 is located within the laser processing area of ​​the laser processing equipment, facilitating the laser processing equipment to perform laser processing on the template workpiece fixed by the clamping component 3. Thus, the processing error of the laser processing equipment can be determined based on the processing trajectory on the template workpiece, providing data for the user to correct the processing error of the laser processing equipment.

[0083] The second limiting unit 10 confines the cantilever 2 to the storage position, ensuring that the cantilever 2 is close to the inner side of the bed 300 of the laser processing equipment. This prevents the cantilever 2 and the clamping assembly 3 from interfering with the laser processing equipment's workpiece processing. By limiting the cantilever 2 with the first limiting unit 9 and the second limiting unit 10, the cantilever 2 can freely reciprocate between the testing position and the storage position.

[0084] In one embodiment, such as Figures 3 to 5 As shown, the first limiting unit 9 includes a fourth fixed base 91, a first limiting shaft 92, and a first limiting member 93. The fourth fixed base 91 is disposed on the first fixed base 4. The first limiting shaft 92 is rotatably disposed on the fourth fixed base 91, and the first limiting member 93 is disposed at the end of the first limiting shaft 92 away from the fourth fixed base 91. The cantilever 2 has a second limiting member 21, which has a limiting groove 211. The width of the first limiting member 93 is greater than the width of the limiting groove 211. The first limiting shaft 92 can rotate into the limiting groove 211 so that the first limiting member 93 is located on the side of the second limiting member 21 away from the fourth fixed base 91. The first limiting member 93 can be a disc nut.

[0085] When the cantilever 2 rotates to the test position, the first limiting shaft 92 rotates, causing it to rotate into the limiting groove 211. The first limiting member 93 is located at the end of the first limiting shaft 92 furthest from the fourth fixed base 91, and the width of the first limiting member 93 is greater than the width of the limiting groove 211, allowing the second limiting member 21 to be positioned between the first limiting member 93 and the fourth fixed base 91. This allows the first limiting member 93 to limit the cantilever 2 through the second limiting member 21, preventing further rotation of the cantilever 2 and thus limiting its movement.

[0086] When the cantilever 2 rotates from the test position to the storage position, the first limiting shaft 92 is rotated so that the first limiting shaft 92 exits the limiting groove 211, so that the cantilever 2 can freely rotate from the test position to the storage position.

[0087] In one embodiment, such as Figure 5 As shown, the second limiting member 21 can be an L-shaped sheet metal part, so as to fix the second limiting member 21 at the corresponding position of the cantilever 2.

[0088] In one embodiment, such as Figure 3 andFigure 4 As shown, the second limiting unit 10 includes a second limiting shaft 101, a third limiting member 102, and a first elastic member. A first limiting hole extending along a first direction is provided on the first fixed base 4, and the second limiting shaft 101 passes through the first limiting hole. The third limiting member 102 is disposed on the second limiting shaft 101, and the third limiting member 102 and the cantilever 2 are respectively located on both sides of the first fixed base 4 along the first direction. One end of the first elastic member is disposed on the second limiting shaft 101, and the other end is disposed on the first fixed base 4. The first elastic member is used to drive the second limiting shaft 101 to move towards the side of the first fixed base 4 away from the third limiting member 102, so that the second limiting shaft 101 protrudes from the side of the first fixed base 4 away from the third limiting member 102. A second limiting hole 22 is provided on the cantilever 2, and the second limiting shaft 101 can be inserted into the second limiting hole 22.

[0089] In this embodiment, the first elastic element can be a spring, and the first elastic element is disposed within the first limiting hole. The third limiting element 102 can be a limiting strip, which can be held by the user.

[0090] The second limiting shaft 101 passes through the first limiting hole, and the third limiting member 102 is disposed on the second limiting shaft 101. The third limiting member 102 and the cantilever 2 are respectively located on both sides of the first fixed seat 4 along the first direction. One end of the first elastic member is disposed on the second limiting shaft 101, and the other end is disposed on the first fixed seat 4. Under its own elastic force, the first elastic member will drive the second limiting shaft 101 toward the side of the first fixed seat 4 away from the third limiting member 102. The third limiting member 102 is located on the side of the first fixed seat 4 away from the cantilever 2, and is used to prevent the second limiting shaft 101 from exiting the first limiting hole from the direction of the first fixed seat 4 away from the third limiting member 102, so that the second limiting shaft 101 will not be driven out of the first limiting hole by the first elastic member. Furthermore, the second limiting shaft 101 protrudes from the side of the first fixed seat 4 away from the third limiting member 102 under the action of the first elastic member.

[0091] When the cantilever 2 rotates to the storage position, the second limiting shaft 101, driven by the first elastic element, inserts into the second limiting hole 22, thereby limiting the cantilever 2 and preventing it from rotating further. When rotating the cantilever 2 from the storage position to the testing position, the third limiting element 102 is pulled towards the side of the first fixed seat 4 away from the cantilever 2, causing the second limiting shaft 101 to disengage from the second limiting hole 22, allowing the cantilever 2 to rotate freely to the testing position.

[0092] In one embodiment, the cantilever 2 is provided with an inclined surface. During the process of rotating the cantilever 2 to the storage position, the inclined surface abuts against the second limiting shaft 101, causing the second limiting shaft 101 to move toward the first fixed seat 4 in a direction away from the cantilever 2. Finally, the second limiting shaft 101 slides into the second limiting hole 22, so as to limit the cantilever 2 to the storage position by means of the second limiting shaft 101.

[0093] In one embodiment, such as Figure 3 and Figure 4 As shown, the error auxiliary correction device 100 further includes a first buffer 20 and a second buffer 30, both of which are disposed on the first fixed base 4. The first buffer 20 is used to block the cantilever 2 at the test position, and the second buffer 30 is used to block the cantilever 2 at the storage position. Both the first buffer 20 and the second buffer 30 are located on the rotation path of the cantilever 2.

[0094] Both the first buffer 20 and the second buffer 30 have a buffering function to prevent the cantilever 2 from experiencing a hard collision. The first buffer 20 and the second buffer 30 also have a limiting function, so that the first buffer 20 can stop the cantilever 2 at the test position, and the second buffer 30 can stop the cantilever 2 at the storage position.

[0095] After the first buffer 20 limits the cantilever 2 to the test position, the first limiting unit 9 further limits the cantilever 2; or after the second buffer 30 limits the cantilever 2 to the storage position, the second limiting unit 10 further limits the cantilever 2. This allows for rapid positioning of the cantilever 2, thereby improving the efficiency of the error auxiliary correction device 100 in assisting to correct the processing errors of the laser processing equipment.

[0096] In this embodiment, both the first buffer 20 and the second buffer 30 can be elastic elements. Specifically, both the first buffer 20 and the second buffer 30 can be rubber pads.

[0097] In one embodiment, such as Figure 3 and Figure 4 As shown, the error auxiliary correction device 100 also includes a sensor switch 40, which is disposed on the first fixed base 4 and is used to detect whether the cantilever 2 is in the storage position.

[0098] After the inductive switch 40 detects that the cantilever 2 is in the storage position, it can transmit the information that the cantilever 2 is in the storage position to the control system so that the control system can continue to execute the instructions for laser processing of the workpiece.

[0099] When the inductive switch 40 does not detect the cantilever 2 in the storage position, the information that the cantilever 2 is not in the storage position can be transmitted to the control system so that the control system can stop executing the instruction to process the workpiece by laser, thereby avoiding the cantilever 2 interfering with the laser processing equipment's processing of the workpiece.

[0100] In one embodiment, such as Figure 3 , Figure 6 and Figure 7 As shown, the error auxiliary correction device 100 also includes a third limiting unit 50, which is disposed on the cantilever 2 and is used to limit the rotation position of the clamping assembly 3. After the cantilever 2 is rotated to the laser processing area of ​​the laser processing equipment, that is, after the cantilever 2 is rotated to the test position, the clamping assembly 3 needs to be rotated to different angles so that the laser processing equipment can perform laser processing on the template workpiece clamped by the clamping assembly 3 at the corresponding angle, thereby collecting and analyzing the processing trajectory on the template workpiece to determine the processing error of the laser processing equipment.

[0101] To improve detection accuracy, after the clamping component 3 is rotated to different angles, the third limiting unit 50 limits the clamping component 3 to prevent it from continuing to rotate. This can improve the stability of the clamping component 3 in clamping the sample workpiece, thereby improving the detection accuracy of the processing error of the laser processing equipment.

[0102] In one embodiment, such as Figure 3 , Figure 6 and Figure 7 As shown, the third limiting unit 50 includes a limiting seat 501, a fourth limiting member 502, and a fifth limiting member 503. The limiting seat 501 is disposed on the cantilever 2. The limiting seat 501 has a square hole 5011 extending along a second direction and a connecting hole, which communicates with the square hole 5011. The square hole 5011 is located at the end of the connecting hole near the clamping assembly 3. The fourth limiting member 502 is movably inserted into the connecting hole along the second direction. The fifth limiting member 503 is disposed at the end of the fourth limiting member 502. The cross-sectional shape of the fifth limiting member 503 is square, corresponding to the square hole 5011, and it is disposed within the square hole 5011. The fifth limiting member 503 can rotate after exiting the square hole 5011, and the clamping assembly 3 is disposed on the fifth limiting member 503.

[0103] The fourth limiting member 502 is movably inserted into the connecting hole along the second direction, and the fifth limiting member 503 is disposed within the square hole 5011. The clamping assembly 3 is disposed on the fifth limiting member 503. The fifth limiting member 503 is prevented from rotating within the square hole 5011 by the limiting effect of the inner wall of the square hole 5011, thereby preventing the clamping assembly 3 from rotating. Furthermore, when the fifth limiting member 503 is withdrawn from the square hole 5011 along the second direction for rotation, the fourth limiting member 502 remains within the connecting hole, preventing it from detaching from the limiting seat 501. After rotating the fifth limiting member 503, it is reinserted into the square hole 5011, so that the inner wall of the square hole 5011 limits the fifth limiting member 503, preventing its rotation.

[0104] In one embodiment, such as Figure 3 , Figure 6 and Figure 7 As shown, the third limiting unit 50 further includes a connecting shaft 504, a stop member 505, and a second elastic member 506. The connecting shaft 504 is located at the end of the fourth limiting member 502 away from the fifth limiting member 503. The stop member 505 is located on the connecting shaft 504, at the end of the connecting hole away from the square hole 5011. One end of the second elastic member 506 abuts against the stop member 505, and the other end of the second elastic member 506 abuts against the limiting seat 501.

[0105] When the fifth limiting member 503 exits the square hole 5011 along the second direction, the fifth limiting member 503 will drive the fourth limiting member 502 to move along the second direction, the fourth limiting member 502 will drive the blocking member 505 to move along the second direction, and the blocking member 505 will compress the second elastic member 506 so that the second elastic member 506 elastically contracts.

[0106] After the external force applied to the fifth limiting member 503 is removed, when the second elastic member 506 is reset, it will cause the blocking member 505 to move in the opposite direction along the second direction. The blocking member 505 will cause the fourth limiting member 502 to move along the second direction. The fourth limiting member 502 will cause the fifth limiting member to move along the second direction, so that the fifth limiting member 503 moves into the square hole 5011.

[0107] In this embodiment, the blocking member 505 can be disc-shaped.

[0108] In one embodiment, the fourth limiting member 502 is provided with a threaded hole, and the connecting shaft 504 is provided with an external thread. The connecting shaft 504 is inserted into the threaded hole to be threadedly connected to the fourth limiting member 502.

[0109] In one embodiment, such as Figure 3 , Figure 6 and Figure 7 As shown, the cantilever 2 can be a square tube, and the third limiting unit 50 is disposed inside the cantilever 2. The side wall of the limiting seat 501 is fixedly connected to the inner wall of the cantilever 2 by screws.

[0110] In one embodiment, such as Figure 6 and Figure 7 As shown, the third limiting unit 50 also includes a retaining ring 507, which is sleeved on the connecting shaft 504. The retaining ring 507 is located between the abutment 505 and the second elastic member 506, with one end of the second elastic member 506 abutting against the retaining ring 507. The abutment 505 is used to block the retaining ring 507 to prevent it from disengaging from the connecting shaft 504 in a direction away from the fourth limiting member 502. The retaining ring 507 is used to abut against the second elastic member 506 to provide a point of force for the second elastic member 506.

[0111] In one embodiment, such as Figure 2 and Figure 3 As shown, the clamping assembly 3 includes a clamping base 31, a pressure plate 32, and a fixing member 33. The clamping base 31 is rotatably disposed at the end of the cantilever 2 away from the mounting base 1. The pressure plate 32 is disposed on the clamping base 31, and a placement space 34 is formed between the pressure plate 32 and the clamping base 31. The pressure plate 32 is provided with a fixing hole, and the fixing member 33 is threadedly connected to the fixing hole. Rotating the fixing member 33 can adjust the length of the fixing member 33 extending into the placement space 34.

[0112] The placement space 34 is used to place the template workpiece. After the template workpiece is placed in the placement space 34, the fixing member 33 is rotated to increase its length extending into the placement space 34, thereby securing the template workpiece against the clamping seat 31, achieving clamping and fixing of the template workpiece. The placement space 34 is used to accommodate the edge of the template workpiece so that the middle part of the template workpiece is exposed above the pressure plate 32, facilitating laser processing of the template workpiece by the laser processing equipment.

[0113] In one embodiment, such as Figure 3 and Figure 7 As shown, the clamping seat 31 is disposed on the fifth limiting member 503.

[0114] In one embodiment, such as Figure 3 and Figure 6 As shown, the cross-sectional shape of the pressure plate 32 is L-shaped. One right-angled side of the pressure plate 32 is fixed to the clamping seat 31, and the other right-angled side of the pressure plate 32 is located directly above the clamping seat 31. A fixing hole is provided on the right-angled side of the pressure plate 32 located directly above the clamping seat 31.

[0115] In addition, such as Figure 1 As shown in the embodiments of this application, a laser processing device is also provided, which includes an error auxiliary correction device 100. The specific structure of the error auxiliary correction device 100 is as described in the above embodiments. Since the laser processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0116] In one embodiment, such as Figures 1 to 3 As shown, the laser processing equipment also includes a base 200, a bed 300, a crossbeam 400, and a laser 500. The bed 300 is equipped with the base 200, the crossbeam 400 is slidably mounted on the bed 300, and the laser 500 is slidably mounted on the crossbeam 400. The sliding direction of the crossbeam 400 is perpendicular to the sliding direction of the laser 500. The mounting base 1 is located on the inner side of the bed 300.
