Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of metal profile processing, and in particular to a profile marking and cutting device and a positioning detection method. Background Art
[0002] Automatic profile cutting production lines are widely used in the current shipbuilding industry. The profile coding and marking process is usually set up together with the cutting process. Since the cutting robot cannot operate simultaneously during the coding and marking process, it must stop and wait for the coding and marking process to complete before cutting the profile. This results in low profile production efficiency and cannot meet subsequent usage needs. With the shipbuilding industry's significantly increased requirements for production output and manufacturing precision, it has become a trend to separate the coding and marking device from the cutting device. After the coding and marking process is completed, the workpiece is automatically transferred to a buffer area at the front end of the cutting device's feed unit. Multiple typical workpieces can be buffered so that the cutting device can cut the marked profiles simultaneously during the coding and marking process. However, this design has high requirements for the positioning accuracy of the profile in both the coding and marking process. If the positioning accuracy is too low, it can easily lead to positioning errors in the profile during the coding and marking process, resulting in defective products and a low profile production yield.

[0028] Preferably, step S3 further includes the following steps:
[0029] S31. Before the pushing mechanism pushes the profile to the feed roller, the second driving structure drives the clamping plate upward to clamp the rotating shaft of the feed roller to prevent the feed roller from rotating. Then the pushing mechanism pushes the profile so that the positioning long side of the profile abuts the second supporting wheel.

[0030] Compared with the prior art, the profile marking and cutting equipment and positioning detection method provided in the embodiment of the present invention have the following beneficial effects: at the coding and marking station, the first limiting mechanism cooperates with the first reference edge to limit the position of the long side of the profile on the marking platform, thereby realizing the positioning of the long side of the profile, and then the coding robot arm drives the marking detection device to move, and the marking detection laser is used as the second reference edge.

The entire feed detection laser is parallel to the marking detection laser. At this time, the positional relationship between the second reference edge and the first reference edge is the same as the positional relationship between the third reference edge and the fourth reference edge. When the profile is pushed by the pushing mechanism on the feed roller to abut the third reference edge, the feed trolley pushes the profile to move in the second direction. When the feed detection laser detects the profile, the profile positioning end face on the cutting device can be positioned, and the profile is cut in the cutting unit based on this positioning information. Since the second reference edge and the fourth reference edge are both detected by laser, the accuracy of repeated positioning is higher and the error is smaller. The contact position of the two lasers with the profile is the same, and the angle between the two lasers and the profile plate surface is also the same. The problem of errors in the two detection positioning caused by factors such as the unevenness of the profile positioning end face can be minimized, thereby further improving the accuracy of the two repeated positioning.

[0042] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0043] like Figures 1 to 7 As shown, a preferred embodiment of the present invention provides a profile marking and cutting device and a positioning detection method, which includes:
[0044] The coding and marking device 1 includes a marking platform 11 and a marking gantry 12. The marking platform 11 is provided with a first limiting mechanism 112 and a first reference edge. The first limiting mechanism 112 is used to push the profile 4 on the marking platform 11 to move in a first direction so that the positioning long side 41 of the profile 4 abuts the first reference edge. A coding robot arm 121 with a marking detection device is slidably connected to the marking gantry 12. The coding robot arm 121 slides along a second direction. The marking detection device emits a marking detection laser 122 as a second reference edge to detect the position of the positioning end face 42 of the positioning profile 4. The emission direction of the marking detection laser 122 is toward the profile 4 and perpendicular to the first reference edge.
[0045] The cutting device 2 includes a cutting and feeding unit 21 and a cutting unit 22. The cutting and feeding unit 21 includes a pushing mechanism 211, a feeding roller 212, a feeding trolley 213 and a feeding detection device. The feeding roller 212 is provided with a third reference edge. The pushing mechanism 211 moves in the opposite direction of the first direction to push the profile 4 on the marking platform 11 to the feeding roller 212, and makes the positioning long side 41 of the profile 4 abut the third reference edge. The feeding trolley 213 and the cutting unit 22 are respectively provided at both ends of the feeding roller 212 along the second direction. The feeding trolley 213 is used to clamp the end of the profile 4 and push the profile 4 to move in the second direction into the cutting unit 22. The cutting unit 22 is used to cut the profile 4 after coding and marking.
[0046] The feed detection device is provided on one side of the feed roller 212 close to the cutting unit 22. The feed detection laser 214 emitted by the feed detection device serves as a fourth reference edge to detect the position of the positioning end surface 42 of the positioning profile 4. The emission direction of the feed detection laser 214 is parallel to the laser emission direction of the marking detection device, and the spatial position of the feed detection device relative to the third reference edge is the same as the spatial position of the marking detection device relative to the first reference edge.
[0047] The positioning long side 41 is perpendicular to the positioning end face 42 ; the first direction is perpendicular to the second direction; and the second direction is parallel to the first reference side and the third reference side.
[0048] Specifically, the first direction is A and the second direction is B. When the profile 4 is subjected to coding and marking operations and cutting operations, the position of the profile 4 in the coding and marking device 1 and the cutting device 2 needs to be kept consistent. This is to ensure the processing accuracy of the profile 4 and reduce processing errors. For the profile 4 to be cut in the shipbuilding industry, the main positioning parameters involved are the length and width of the profile 4. Since the coding and marking device 1 and the cutting device 2 are set separately, when the profile 4 is transferred between the two processes, it is difficult to ensure that the position of the profile 4 on the coding and marking device 1 is the same as the position on the cutting device 2. In the prior art, there is also an accuracy error between the two positioning of the profile 4, and it is difficult to ensure that the position of the profile 4 on the two workstations is consistent, which brings about the problem of low subsequent processing accuracy. In the present invention, the center line pushes the profile 4 through the first limiting mechanism 112, so that the positioning long side 41 of the profile 4 is aligned with the second limiting mechanism 112 on the marking platform 11. A reference edge is abutted, thereby realizing the positioning of the long side of the profile 4. When the position of the long side of the profile 4 is determined, the coding robot arm 121 drives the marking detection device to move toward the positioning end face 42 of the profile 4, wherein the positioning long side 41 is perpendicular to the positioning end face 42. When the marking detection laser 122 detects the positioning end face 42 of the profile 4, the real-time spatial position relationship between the marking detection device and the first reference edge can be known through the coding robot arm 121. The emission angle information of the marking detection laser 122 can also be obtained through the coding robot arm 121. At this time, the position of the contact point of the marking detection laser 122 and the profile 4 and the inclination angle of the marking detection laser 122 relative to the profile 4 plate surface can be accurately adjusted according to the trigonometric function, thereby realizing the detection and positioning of the positioning end face 42 of the profile 4. When the profile 4 completes the detection and positioning on the marking platform 11, the coding robot arm 121 can perform coding and marking on the profile 4 according to the positioning information.
[0049] When the coding and marking are completed, the pushing mechanism 211 pushes the profile 4 into the feed roller 212 and pushes the profile 4 so that the positioning long side 41 of the profile 4 abuts against the third reference side. At this time, the positioning of the positioning long side 41 of the profile 4 on the cutting device 2 is completed. When the position of the positioning long side 41 of the profile 4 on the cutting device 2 is determined, the clamping trolley clamps the end of the profile 4 and pushes the profile 4 toward the cutting unit 22. The feed detection device is set on the side of the feed roller 212 close to the cutting unit 22, wherein the position of the feed detection device relative to the third reference side is consistent with the marking detection device. The positions relative to the first reference edge are the same, and the feed detection laser 214 is parallel to the marking detection laser 122, and the positioning long side 41 of the profile 4 is respectively in contact with the first reference edge and the second reference edge. According to the trigonometric function, it can also be known that the contact point between the feed detection laser 214 and the profile 4 is the same as the contact point between the marking detection laser 122 and the profile 4, and the inclination angles of the two lasers relative to the profile 4 are also the same. This can maximize the accuracy of the two repeated positioning of the positioning end face 42 of the profile 4, and reduce the error between the two positioning caused by the uneven positioning end face 42 of the profile 4.
[0050] See also Figures 1 to 4 In one embodiment, the marking platform 11 includes a plurality of marking carriers 111 evenly distributed along the second direction, and a marking gantry 12 is positioned above the marking platform 11 in the second direction. Specifically, because the profile 4 is large and long, multiple marking carriers 111 are provided to carry the profile 4 to be coded and marked. This saves costs and allows for better movement of the profile 4. The positioning of the marking gantry 12 above the marking platform 11 facilitates the movement of the coding robot 121 on the marking platform 11, enabling the coding robot 121 to better move in the second direction to code and mark the profile 4.
[0051] In one embodiment, a baffle 1111 is provided at one end of the marking carrier 111, and the first reference edge is provided on the vertical plate surface of the baffle 1111; the first limiting mechanism 112 includes a slide 1121 slidably connected to the side of the marking carrier 111, a first supporting wheel 1122 is fixed to the top of the slide 1121, and a telescopic cylinder 1123 is connected to the bottom of the slide 1121, the telescopic cylinder 1123 is used to push the slide 1121 to slide toward the baffle 1111, and the first supporting wheel 1122 is used to push the profile 4 so that the positioning long side 41 of the profile 4 abuts against the baffle 1111.
[0052] Specifically, when the first limiting mechanism 112 is in the process of limiting the profile 4, when the sensor detects that the profile 4 has been transported to the marking carrier 111, the telescopic cylinder 1123 starts and pushes the slide 1121 to move on the side of the marking carrier 111, and the slide 1121 drives the first supporting wheel 1122 thereon to move in the first direction and push the profile 4, so that the positioning long side 41 of the profile 4 abuts against the baffle 1111 on the marking carrier 111. At this time, the detection and positioning of the long side of the profile 4 on the marking platform 11 is completed. In some other embodiments, the telescopic cylinder 1123 can be a pneumatic cylinder, a hydraulic cylinder or an electric cylinder, or a stepping structure such as a screw to push the slide plate 1121 and the first wheel 1122 to slide on the marking carrier 111; through the first wheel 1122 and the telescopic cylinder 1123 and other structures, the profile 4 can be quickly abutted and positioned against the baffle 1111, which is convenient for the subsequent marking detection device to detect and position the deployment, and the detection and positioning efficiency is higher. Since there are multiple marking carriers 111, there are also multiple baffles 1111, and the positioning of the long side 41 of the profile 4 on the marking platform 11 is more accurate and reliable, and this positioning structure is simpler and the positioning is more stable.
[0053] In one embodiment, a first pushing cavity 1112 is provided in the middle of the scribing carrier 111 along the first direction, and both ends of the first pushing cavity 1112 pass through the scribing carrier 111; the scribing carrier 111 is also provided with an upwardly inclined guide surface 1113 corresponding to the first supporting wheel 1122;
[0054] The pushing mechanism 211 includes a pushing rack 2111 with one end arranged in the first pushing cavity 1112, a transmission wheel is provided in the pushing rack 2111, and a first transmission chain structure 2112 that can move along the first direction is provided on the transmission wheel. A pushing block 2113 is fixed on the first transmission chain structure 2112, and the pushing block 2113 moves in the opposite direction of the first direction to push the profile 4 on the marking carrier 111 to the feed roller 212 through the guide surface 1113.
[0055] Specifically, when the profile 4 is marked, the transmission wheel drives the first transmission chain structure 2112 to move in the opposite direction of the first direction under the drive of the motor and other driving structures. The push block 2113 on the first transmission chain structure 2112 moves counterclockwise from the bottom to the positioning long side 41 of the profile 4, and abuts against the positioning long side 41 of the profile 4, and then pushes the profile 4 to move in the direction of the feed roller 212 until the profile 4 after the coding and marking is pushed onto the feed roller 212; wherein the guide The height of the surface 1113 is higher than the height of the first supporting wheel 1122. When the push block 2113 pushes the profile 4 to move to the guide surface 1113, the height of the profile 4 will also be higher than the height of the first supporting wheel 1122. At this time, the push block 2113 can smoothly push the profile 4 into the feed roller 212 in the opposite direction of the first direction. Its driving structure is simpler and more reliable, and it also eliminates the trouble of manually transferring the profile 4 to the feed track through a trolley or other device, which saves time and effort and is more efficient.
[0056] See also Figure 1 、 Figure 5 and Figure 6 In one embodiment, the feed roller 212 includes a plurality of feed platforms 2121 evenly distributed along the second direction, a second pushing cavity 2122 is provided between adjacent feed platforms 2121, and the other end of the pushing rack 2111 is provided in the second pushing cavity 2122; the pushing block 2113 moves in the first direction to push the positioning edge of the profile 4 to abut against the third reference edge.
[0057] In one embodiment, a groove 2123 is provided on the feeding platform 2121, and a first driving structure 2124 and a second supporting wheel 2125 are provided in the groove 2123. The first driving structure 2124 is used to drive the second supporting wheel 2125 to be lifted up, and the second supporting wheel 2125 is used to abut the positioning long side 41 of the profile 4. The third reference side is provided on the second supporting wheel 2125.
[0058] Specifically, after the pushing block 2113 pushes the profile 4 to the feeding platform 2121, the transmission wheel drives the first transmission chain structure 2112 to rotate clockwise along the first direction, and the pushing block 2113 moves and abuts against the other long side of the profile 4, and then the pushing block 2113 pushes the profile 4 to move in the first direction until the positioning long side 41 of the profile 4 abuts against the third reference side, completing the preliminary positioning of the profile 4 on the cutting device 2; wherein, a second supporting wheel 2125 is provided in the groove 2123 of the feeding platform 2121, and when the pushing block 2113 pushes the profile 4 to the feeding platform 2121, the second supporting wheel 2125 is received in the groove 2123 under the drive of the first driving structure 2124. The push block 2113 is arranged inside so that the profile 4 can be smoothly pushed onto the feed platform 2121. When the push block 2113 moves clockwise and pushes the profile 4, the second supporting wheel 2125 moves upward under the action of the first driving structure 2124 and protrudes from the surface of the feed platform 2121. The push block 2113 pushes the profile 4 so that the positioning long side 41 of the profile 4 abuts against the second supporting wheel 2125, thereby completing the preliminary positioning of the profile 4. This structure is simpler and more stable, and the preliminary positioning of the profile 4 is also achieved by abutting the positioning long side 41 of the profile 4. The positioning consistency of the profile 4 in the coding and marking device 1 and the cutting device 2 is better, and the error is also lower.
[0059] In one embodiment, the feed platform 2121 is also provided with a feed roller 2126 and a clamping mechanism. The feed roller 2126 is used to guide the profile 4 to move to the cutting unit 22. The clamping mechanism includes a clamping plate 2127 adapted to the rotating shaft of the feed roller 2126 and a second drive structure. The second drive structure is used to drive the clamping plate 2127 close to or away from the rotating shaft of the feed roller 2126 to limit the rotation of the feed roller 2126.
[0060] Specifically, due to the large volume and weight of the profile 4, the friction between the profile 4 and the feed platform 2121 is also large. The feed roller 2126 is provided to facilitate the feed trolley 213 to push the profile 4 to move on the feed roller 212, increase the speed at which the feed trolley 213 pushes the profile 4 to move, improve the positioning and cutting efficiency, and avoid friction damage between the profile 4 and the feed platform 2121; in the process of the push block 2113 pushing the profile 4 to the feed platform 2121 and the process of the push block 2113 pushing the profile 4 to abut against the second supporting wheel 2125, the feed roller 212 6 needs to be kept in a locked state to prevent the rotation of the feed roller 2126 from adversely affecting the position of the profile 4. When the feed roller 2126 needs to be locked, the second drive structure will drive the clamping plate 2127 upward to limit the rotating shaft of the feed roller 2126 to prevent the feed roller 2126 from rotating. After the profile 4 is initially positioned, the feed trolley 213 pushes the profile 4 into the cutting unit 22. The second drive structure drives the clamping plate 2127 downward, and the feed roller 2126 can rotate, thereby assisting the feed trolley 213 to push the profile 4 into the cutting unit 22.
[0061] See also Figure 1 and Figure 7 In one embodiment, the apparatus further includes a loading device 3 for storing the profile 4 and conveying the profile 4 to the coding and marking device 1; the loading device 3 includes a plurality of loading buffer mechanisms 31 and a conveying mechanism 32 corresponding to the marking carrier 111, the loading buffer rack is used to store the profile 4 to be processed, and the conveying mechanism 32 is used to convey the profile 4 stored in the loading buffer rack to the coding and marking device 1;
[0062] The loading and caching mechanism 31 includes a second transmission chain structure 311 and a third driving structure 312 that drives the second transmission chain structure 311 to move along the first direction; the conveying mechanism 32 includes a third transmission chain structure 321, a fourth driving structure 322 that drives the third transmission chain structure 321 to move along the first direction, and a supporting mechanism 323. The third transmission chain structure 321 and the second transmission chain structure 311 are both arranged in multiples along the second direction, and the third transmission chain structure 321 and the second transmission chain structure 311 are staggered. The supporting mechanism 323 is arranged at one end of the third transmission chain structure 321 away from the second transmission chain structure 311. The supporting mechanism 323 is used to drive the third transmission chain structure 321 to rotate around its other end, and the rotating surface of the third drive chain is parallel to the first direction.
[0063] The plurality of third transmission chain structures 321 and the plurality of scribing carriers 111 are alternately arranged in the second direction.
[0064] Specifically, the loading buffer mechanism 31 can buffer multiple profiles 4 to be processed. When the profile 4 needs to be processed, the third driving structure 312 drives the second transmission chain structure 311 to move in the opposite direction of the first direction, and then transports the profile 4 on the loading buffer mechanism 31 to the conveying mechanism 32, and then the fourth driving structure 322 continues to drive the profile 4 on the conveying mechanism 32 to move in the opposite direction of the first direction to above the marking carrier 111, and then the supporting mechanism 323 drives the end of the third transmission chain structure 321 to rotate, so that the end of the third transmission chain structure 321 rotates counterclockwise downward. Since the third transmission chain structure 321 and the marking carrier 111 are arranged in an staggered manner and the end of the third transmission chain structure 321 is located between adjacent marking carriers 111, as the third transmission chain structure 321 descends, the profile 4 on the third transmission chain structure 321 is placed on the marking carrier 111; the above-mentioned structure for conveying profiles 4 is simpler and more reliable, and can buffer and convey multiple profiles 4, thereby improving the processing efficiency of the profiles 4.
[0065] See also Figure 1 In one embodiment, the cutting device 2 further includes a cutting and discharging unit 23, which is disposed at an end of the cutting unit 22 away from the cutting and feeding unit 21. The cutting and discharging unit 23 is provided with a plurality of discharging rollers along the second direction. The discharging rollers are disposed at the outlet of the cutting unit 22 and can assist in conveying and storing the cut profile 4.
[0066] In one embodiment, the angle between the emission direction of the marking detection laser 122 and the surface of the profile 4 is 20° to 30°, and the contact point between the marking detection laser 122 and the surface of the profile 4 is 4150mm away from the long positioning side of the profile 4. In a specific embodiment, the angle between the marking detection laser 122 and the feed detection laser 214 and the surface of the profile 4 is 30°, and the two lasers are oriented in the same direction. By adjusting the position of the marking detection device and the position of the feed detection device, the contact points of the two lasers with the profile 4 are the same, and both are 4150mm away from the long positioning side of the profile 4. This ensures consistency when the two lasers serve as the second reference edge and the fourth reference edge respectively to detect and position the positioning end face 42 of the profile 4. The error of the two repeated positioning detections is smaller and the accuracy is higher.
[0067] In one embodiment, the profile 4 is provided with a protruding ball head 43 on the side corresponding to the positioning long side 41. The provision of the ball head 43 can more conveniently determine the position and direction of the positioning long side 41 of the profile 4, avoiding problems such as incorrect placement of the profile 4.
[0068] The present invention also provides a method for detecting the positioning of a profile 4 during line cutting, comprising the following steps:
[0069] S1. The first limiting mechanism 112 pushes the profile 4 on the marking platform 11 to move in the first direction until the positioning long side 41 of the profile 4 abuts the first reference side. Then, the coding robot arm 121 moves on the marking gantry 12 in the opposite direction of the second direction until the marking detection laser 122 detects the profile 4. Then, the coding robot arm 121 adjusts the spatial position of the marking detection device relative to the first reference side and makes the marking detection laser 122 emit at a preset angle, thereby completing the detection and positioning of the profile 4 on the marking platform 11.
[0070] S2, the coding robot arm 121 moves along the second direction on the marking gantry 12 to complete the coding and marking operation;
[0071] S3, the first limiting mechanism 112 returns to its original position, and the pushing mechanism 211 moves in the opposite direction of the first direction to push the profile 4 after coding and marking to the feed roller 212, and then the pushing mechanism 211 reverses and moves to the other side of the profile 4 and moves in the first direction to push the profile 4 so that the positioning long side 41 of the profile 4 abuts the third reference side; then the feeding trolley 213 is driven, the feeding trolley 213 clamps the end of the profile 4 and pushes the profile 4 to move in the second direction until the feeding detection laser 214 detects the profile 4, completing the positioning of the profile 4 on the feed roller 212, wherein the contact point of the feeding detection laser 214 with the profile 4 is the same as the contact point of the marking detection laser 122 with the profile 4, and the angle between the emission direction of the feeding detection laser 214 and the surface of the profile 4 is the same as the angle between the emission direction of the marking detection laser 122 and the surface of the profile 4;
[0072] S4. The feeding trolley 213 continues to push the profile 4 to move in the second direction and enter the cutting unit 22. The cutting unit 22 cuts the profile 4 according to the positioning information of the feeding detection device.
[0073] Specifically, the profile 4 is positioned twice in the coding and marking device 1 and the cutting device 2. The profile 4 is initially positioned by first placing the positioning long side 41 of the profile 4 against the first reference side or the third reference side. Then, the positions of the marking detection device and the feed detection device are adjusted based on the first reference side and the third reference side, respectively, so that the emission directions of the marking detection laser 122 and the feed detection laser 214 are the same, and the positions of the contact points with the profile 4 are the same, thereby improving the accuracy of the two repeated positioning, avoiding the two repeated positioning errors caused by different detection positioning points, and reducing the processing error.
[0074] In one embodiment, step S1 further includes the following steps:
[0075] S11. The loading buffer mechanism 31 stores a plurality of profiles 4 to be processed. The third driving structure 312 drives the second transmission chain structure 311 to move in the opposite direction of the first direction to transport the profiles 4 on the loading buffer mechanism 31 to the conveying mechanism 32. The fourth driving structure 322 in the conveying mechanism 32 drives the third transmission chain structure 321 to move in the opposite direction of the first direction to transport the profiles 4 to be processed to the top of the marking carrier 111. The rear support mechanism 323 drives the end of the third transmission chain structure 321 to rotate downward, and the profiles 4 are placed on the marking carrier 111.
[0076] Among them, multiple profiles 4 can be cached on the loading buffer mechanism 31. When the third transmission chain structure 321 places the profile 4 on the marking carrier 111 under the drive of the top support structure, since the third transmission chain structure 321 is tilted downward, the new profile 4 to be processed on the conveying mechanism 32 cannot be conveyed to the marking carrier 111. When the previous profile 4 is sprayed and marked and is conveyed to the feed roller 212, the third transmission chain structure 321 can rotate upward under the drive of the top support structure, and then smoothly convey the new profile 4 to be processed to the marking carrier 111. The conveying process is more compact and the operation efficiency is higher.
[0077] In one embodiment, step S3 further includes the following steps:
[0078] S31. Before the pushing mechanism 211 pushes the profile 4 to the feed roller 212, the second driving structure drives the clamping plate 2127 upward to clamp the rotating shaft of the feed roller 2126 to prevent the feed roller 2126 from rotating. Then, the pushing mechanism 211 pushes the profile 4 so that the positioning long side 41 of the profile 4 abuts the second supporting wheel 2125. Then, the second driving structure drives the clamping plate 2127 downward, and the feed trolley 213 begins to clamp the end of the profile 4 and pushes the profile 4 to move in the second direction on the feed roller 212.
[0079] Among them, the setting of the clamping plate 2127 enables the feed roller 2126 to be restricted. When the push block 2113 pushes the profile 4 to move on the feed roller 212, the clamping plate 2127 can limit the rotation of the feed roller 2126 to prevent the feed roller 2126 from affecting the position of the profile 4 due to rotation. When the profile 4 abuts against a third reference edge under the action of the push block 2113 and the profile 4 is stably clamped by the feed trolley 213, the clamping plate 2127 can feed the feed roller 2126, so that the feed roller 2126 can rotate and assist the feed trolley 213 in transporting the profile 4 to the cutting unit 22.
[0080] In summary, the embodiment of the present invention provides a profile 4 marking and cutting device and positioning detection method. The profile 4 is firstly positioned on the marking platform 11 by the first reference edge for the positioning long side 41 of the profile 4, and then, based on the first reference edge, the marking detection laser 122 is used as the second reference edge to detect and position the positioning end face 42 of the profile 4; the profile 4 is firstly positioned on the feed roller 212 by the third reference edge for the positioning long side 41 of the profile 4, and then, based on the third reference edge, the feed detection laser 122 is used to detect and position the positioning end face 42 of the profile 4. The measuring laser 214 is used as the fourth reference edge to detect and position the positioning end face 42 of the profile 4, wherein the detecting laser is parallel to the feeding detecting laser 214, and has the same angle with the plate surface of the profile 4, and the position of the contact point with the profile 4 is also the same, which improves the positioning accuracy of the positioning end face 42 of the profile 4 twice, avoids the error of repeated positioning caused by the uneven end face of the profile 4 and the different contact points between the laser and the profile 4 twice, improves the accuracy of repeated positioning, and thus improves the processing accuracy of the profile 4.
[0081] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
