[0043] As described in the background technology, during the assembly process of the line laser, the laser needs to be debugged after the initial assembly is completed. During the debugging process, the Powell prism of the laser can be adjusted or replaced so that the accuracy of the linear laser projected by the line laser after assembly can meet the requirements.

[0044] In the related art, the debugging personnel debug the laser by directly observing the laser projected image with their eyes. Since the brightness of the laser projected image is high, it is not easy to directly observe the laser projected image with the eyes, which makes it difficult to debug the laser and the debugging stability is poor. In addition, the human eye is prone to fatigue when directly observing the laser projected image for a long time. When the human eye is fatigued, it will further increase the difficulty of debugging and reduce the stability of debugging. In addition, the precision of the debugged linear laser is low.

[0045] Figure 1 A front view schematic diagram of a line laser debugging device provided by an embodiment of the present disclosure, Figure 2 for Figure 1 The three-dimensional structural schematic diagram of the line laser debugging device is shown.

[0046] In view of this, see Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a line laser debugging device, which includes a base member 100, a laser fixing assembly 200 for mounting a laser 700, a cylindrical mirror assembly 300, a laser receiving screen assembly 400, and a laser image acquisition assembly 500 for acquiring a laser projection image on the laser receiving screen.

[0047] Continue to see Figure 1 and Figure 2As shown, the laser fixing assembly 200, the cylindrical mirror assembly 300 and the laser receiving screen assembly 400 are sequentially arranged along the laser projection direction X. The cylindrical mirror assembly 300 includes a cylindrical mirror 310 and a driving device 320. The cylindrical mirror 310 is mounted on the driving device 320. The driving device 320 is used to drive the cylindrical mirror 310 to move along the screen width direction Y of the laser receiving screen assembly 400, so that the cylindrical mirror 310 can be aligned or staggered with the laser 700 in the laser projection direction X, and then the laser emitted by the laser 700 can be irradiated onto the laser receiving screen assembly 400 or onto the laser bearing screen assembly after passing through the cylindrical mirror 310.

[0048] During the debugging process, the laser 700 is first mounted on the laser fixing assembly 200, and the laser is emitted toward the laser receiving screen assembly 400 (eg Figure 1 or Figure 2 As shown in A in the figure, the laser image acquisition component 500 can acquire the laser projection image, and judge whether the accuracy of the laser emitted by the laser 700 meets the requirements according to the laser projection image, so as to debug the laser 700. After the laser 700 meets the requirements, the cylindrical mirror 310 is controlled to move so that the laser emitted by the laser 700 passes through the cylindrical mirror 310 and irradiates the laser receiving screen component 400, and then the laser projection image obtained by the laser image acquisition component 500 is debugged.

[0049] Compared with the scheme in which the debugging personnel directly observe the laser projected image to debug the laser 700, observing the image acquired by the laser image acquisition component 500 is not easy to cause eye fatigue, and it is also convenient to observe the image, thereby reducing the difficulty of debugging the laser 700 and improving the stability of debugging. In addition, debugging the laser 700 first, and then debugging the state of the laser 700 and the cylindrical mirror 310 when cooperating, can further improve the accuracy of the linear laser.

[0050] Exemplarily, the debugging personnel can debug the laser 700 by observing the laser projection image acquired by the displayed laser image acquisition component 500. The laser projection image acquired by the laser image acquisition component 500 can be directly displayed by the laser image acquisition component 500 or transmitted to other display devices for display.

[0051] For example, the laser image acquisition component 500 may be connected to a computer for communication, and the laser projection image acquired by the laser image acquisition component 500 may be sent to the computer for display.

[0052] Exemplarily, the laser projection image acquired by the laser image acquisition component 500 may also be processed using existing image processing technology to obtain characteristic parameters, so that the debugging personnel can debug the laser 700 according to the characteristic parameters.

[0053] For example, the computer that is communicatively connected to the laser image acquisition component 500 may be equipped with existing machine vision system processing software, which can process the laser projection image to obtain characteristic parameters of the laser projection image. The debugging personnel can perform debugging based on the characteristic parameters to further reduce the difficulty of debugging and improve the stability of debugging.

[0054] At least one of the laser fixing assembly 200 and the cylindrical mirror assembly 300 is slidably connected to the base member 100, so that the laser fixing assembly 200 or the cylindrical mirror assembly 300 moves relative to the laser receiving screen assembly 400 along the laser projection direction X. In this way, the position of at least one of the laser fixing assembly 200 and the cylindrical mirror assembly 300 can be adjusted relative to the laser receiving screen assembly 400, which is convenient for debugging of a variety of different lasers 700.

[0055] Exemplarily, the laser fixing assembly 200 and the cylindrical mirror assembly 300 are both slidably connected to the base assembly 100, and the laser fixing assembly 200 and the cylindrical mirror assembly 300 can both move along the laser projection direction X, so that the distance between the laser receiving screen assembly 400 and any one of the laser fixing assembly 200 and the cylindrical mirror assembly 300 in the laser projection direction X is variable.

[0056] In some possible implementations, see Figure 1 and Figure 2 As shown, the line laser debugging device further includes a moving platform 600, which is slidably connected to the base member 100, and the moving platform 600 is used to move along the laser projection direction X. At least one of the laser fixing assembly 200 and the cylindrical mirror assembly 300 is slidably connected to the moving platform 600, so that the laser fixing assembly 200 or the cylindrical mirror assembly 300 moves along the laser projection direction X.

[0057] In this way, the laser fixing assembly 200 and the cylindrical mirror assembly 300 are both slidably connected to the base member 100 through the mobile platform 600, so that the laser fixing assembly 200 and the cylindrical mirror assembly 300 can move along the laser projection direction X, meeting the debugging requirements of different lasers 700 and / or line lasers. In addition, at least one of the laser fixing assembly 200 and the cylindrical mirror assembly 300 is slidably connected to the mobile platform 600, and the positions of the laser fixing assembly 200 and the cylindrical mirror assembly 300 can be further adjusted, which can further meet the debugging requirements of different lasers 700 and / or line lasers.

[0058] For example, see Figure 1 and Figure 2As shown, the mobile platform 600 may include a first guide member 610 and a platform member 620. The platform member 620 is slidably connected to the base member 100 and fixedly connected to the first guide member 610. The extension direction of the first guide member 610 is parallel to the laser projection direction X, and the laser fixing assembly 200 and the cylindrical mirror assembly 300 are slidably connected to the first guide member 610 respectively.

[0059] Exemplarily, the first guide member 610 may be a slide rail extending along the laser projection direction X.

[0060] For example, see Figure 1 and Figure 2 As shown, the cylindrical mirror assembly 300 further includes a first slide member 330, a first end of the driving device 320 is fixedly connected to the first slide member 330, a second end of the driving device 320 is fixedly connected to the cylindrical mirror 310, and the first slide member 330 is slidably connected to the first guide member 610. In this way, the position of the cylindrical mirror assembly 300 relative to the laser receiving screen assembly 400 can be changed to meet the debugging of different lasers 700.

[0061] Exemplarily, the first sliding seat 330 may include a first seat body and a first locking mechanism, the first seat body is slidably connected to the first guide member 610, and the first locking mechanism is used to lock or release the first seat body and the first guide member 610, so that the first seat body switches between a sliding state and a fixed state. When the first locking mechanism locks the first seat body and the first guide member 610, the first seat body cannot move along the first guide member 610. When the first locking mechanism releases the first seat body and the first guide member 610, the first seat body can move along the first guide member 610. In this way, the position of the cylindrical mirror 310 can remain unchanged.

[0062] It should be noted that, in addition to being slidably connected to both the laser fixing assembly 200 and the cylindrical mirror assembly 300 , in some embodiments, the first guide member 610 may also be slidably connected to one of the laser fixing assembly 200 and the cylindrical mirror assembly 300 .

[0063] For example, see Figure 1 and Figure 2 As shown, the base member 100 may include two second guide members 110 spaced apart along the screen length direction Z of the laser receiving screen assembly 400, and the extension direction of each second guide member 110 is parallel to the laser projection direction X. One of the second guide members 110 is slidably connected to the mobile platform 600, and the other second guide member 110 is slidably connected to the laser image acquisition assembly 500, so that the mobile platform 600 and the laser image acquisition assembly 500 move along the laser projection direction X.

[0064] Exemplarily, the second guide member 110 may be a slide rail extending along the laser projection direction X.

[0065] For example, see Figure 1 and Figure 2 As shown, the base member 100 may further include a bottom plate 120, and the two second guide members 110 and the laser bearing screen assembly are both mounted on the bottom plate 120, and the two guide members are located on the same side of the laser bearing screen assembly.

[0066] For example, see Figure 1 and Figure 2 As shown, the mobile platform 600 may further include a first locking member 630, and the first locking member 630 has a locking position and a releasing position. When the first locking member 630 is in the locking position, the positions of the platform member 620 and the second guide member 110 are locked, and the platform member 620 cannot slide relative to the second guide member 110 along the laser projection direction X. When the first locking member 630 is in the releasing position, the platform member 620 can slide along the second guide member 110. In this way, it is convenient to adjust the cylindrical mirror 310 and the laser receiving screen assembly 400 to a preset distance, so that the distance between the cylindrical mirror 310 and the laser receiving screen assembly 400 is maintained.

[0067] Exemplarily, the first locking member 630 can be a first locking bolt, the platform member 620 is provided with a slide groove for accommodating the second guide member 110 and a threaded hole connected to the slide groove, the first locking bolt is passed through the threaded hole, and the first locking bolt is used to abut against the second guide member 110 to lock the position of the platform member 620 and the second guide member 110.

[0068] Figure 3 for Figure 2 Enlarged schematic diagram of the dotted line in the middle.

[0069] In some possible implementations, see Figure 2 and Figure 3 As shown, the laser fixing assembly 200 includes a support structure 210 and a fixing structure 220. A slot 211 for accommodating the laser 700 is arranged on the support structure 210 along the laser projection direction X, and at least one of the support structure 210 and the cylindrical mirror assembly 300 is slidably connected to the base member 100. The fixing structure 220 is disposed at the opening of the slot 211 and is detachably connected to the fixing structure 220, so that the laser 700 remains in a state of being inserted into the slot 211.

[0070] In this way, the laser 700 is clamped in the clamping slot 211 , and after the fixing structure 220 clamps the laser 700 , the fixing is relatively stable, and it is convenient to maintain an alignment state with the cylindrical mirror 310 of the cylindrical mirror assembly 300 .

[0071] For example, see Figure 1 and Figure 2 As shown, the laser fixing assembly 200 also includes a second slide member 230, which is slidably connected to the first guide member 610 and fixedly connected to the support structure 210. The second slide member 230 may include a second seat body and a second locking mechanism, the second seat body is slidably connected to the second guide member 110, and the second locking mechanism is used to lock or release the second seat body and the second guide member 110, so that the second seat body switches between a sliding state and a fixed state. When the second locking mechanism locks the second seat body and the second guide member 110, the second seat body cannot move along the second guide member 110. When the second locking mechanism releases the second seat body and the second guide member 110, the second seat body can move along the second guide member 110. In this way, the position of the laser 700 can remain unchanged.

[0072] Figure 4 A schematic diagram of the coordination between a fixing structure and a supporting structure provided in an embodiment of the present disclosure.

[0073] In some possible implementations, see Figure 4 As shown, the fixing structure 220 includes a pressure cover 221, a connecting member 222 and an elastic member 223. The connecting member 222 is used to connect at least one set of opposite sides of the pressure cover 221 to the opening position of the card slot 211 in a detachable manner, so that it is easy to realize the detachable connection between the fixing structure 220 and the support structure 210 and the clamping of the laser 700 in the card slot 211. The elastic member 223 is compressed and installed between the fixing side of the pressure cover 221 and the support structure 210. In this way, the pressing force of the pressure cover 221 on the laser 700 can be more uniform and stable.

[0074] Exemplarily, the connection member 222 may be a threaded fastener that is penetrated through the gland 221 and threadedly connected to the support structure 210 .

[0075] Exemplarily, the connecting member 222 may also be a clamping member having a structure such as a claw.

[0076] In some possible implementations, a first accommodating groove corresponding one-to-one to the elastic member 223 is provided on the side of the pressure cover 221 facing the support structure 210, and a second accommodating groove corresponding one-to-one to the elastic member 223 is provided on the fixed side of the support structure 210, one end of the elastic member 223 is provided in the corresponding first accommodating groove, and the other end of the elastic member 223 is provided in the corresponding second accommodating groove.

[0077] In this way, it is relatively easy to arrange the elastic member 223 between the pressure cover 221 and the support structure 210. In addition, the arranged elastic member 223 is not easily displaced due to extrusion.

[0078] For example, the elastic member 223 may be a column spring, a disc spring, etc. In addition, the elastic member 223 may be sleeved on the outer wall of the connecting member 222 and be clearance-matched with the connecting member 222, for example Figure 4 shown.

[0079] In some possible implementations, see Figure 3 As shown, a pressing groove 224 is provided on one side of the pressing cover 221 facing the card slot 211. The pressing groove 224 and the card slot 211 clamp the laser 700 relatively when the pressing cover 221 is closed at the opening of the card slot 211. At least one of the pressing groove 224 and the card slot 211 is configured such that two groove walls on opposite sides gradually approach each other and tilt in a direction close to the groove bottom. For example, Figure 3 As shown, the pressing groove 224 and the clamping groove 211 are both arranged such that two groove walls on opposite sides gradually approach and incline toward each other in a direction approaching the groove bottom.

[0080] In this way, the laser 700 is stably clamped in the clamping slot 211 , which helps to keep the laser 700 clamped in the clamping slot 211 aligned with the cylindrical mirror 310 of the cylindrical mirror assembly 300 .

[0081] In some possible implementations, see Figure 1 and Figure 2 As shown, the laser image acquisition assembly 500 includes an industrial camera 510, a lifting rail 520 and a moving part 530. The industrial camera 510 is mounted on the moving part 530 and arranged toward the laser receiving screen assembly 400. The lifting rail 520 is mounted on the base member 100 and is movably connected to the moving part 530, so that the moving part 530 moves along the screen width direction Y of the laser receiving screen.

[0082] In this way, the industrial camera 510 can be raised and lowered with the movable component 530 to adjust the relative position of the laser projection image and the industrial camera 510 in the screen width direction Y of the receiving screen assembly, thereby facilitating the shooting of laser projection images at different positions in the screen width direction Y of the receiving screen assembly.

[0083] See also Figure 1 and Figure 2 As shown, the lifting rail 520 is installed on the bottom plate 120 to achieve the connection between the base member 100 and the laser image acquisition assembly 500.

[0084] Exemplarily, the moving component 530 may be directly slidably connected to the lifting rail 520 , or may be slidably connected to the lifting rail 520 via a structure such as a conveyor belt or a chain.

[0085] In some possible implementations, see Figure 1 and Figure 2As shown, the moving part 530 may include a mounting plate 531 and a rotating assembly 532. The industrial camera 510 is fixedly mounted on the mounting plate 531. The first end of the rotating assembly 532 is slidably connected to the lifting rail 520, and the second end of the rotating assembly 532 is fixedly connected to the mounting plate 531. The rotating assembly 532 is used to realize the rotational connection between the mounting plate 531 and the lifting rail 520 to change the shooting direction of the industrial camera 510 relative to the laser receiving screen assembly 400.

[0086] In this way, the industrial camera 510 can rotate relative to the laser receiving screen assembly 400, and the angle of the laser projected image on the camera shooting surface can be adjusted to facilitate the acquisition of a relatively easy-to-process horizontal image.

[0087] The specific structure of the rotating assembly 532 is not limited here. For example, the rotating assembly 532 may include a rotating member, a sliding member, and a third locking mechanism. The sliding member is slidably connected to the lifting rail 520. The rotating member is rotatably connected to the sliding member and is fixedly connected to the mounting plate 531. The third locking mechanism is used to lock or release the rotating member and the sliding member, so that the rotating member remains stationary relative to the sliding member or the rotating member can rotate relative to the sliding member.

[0088] In some possible implementations, the mounting plate 531 includes a plurality of mounting positions arranged along the screen length direction Z of the laser receiving screen assembly 400 , and the industrial camera 510 is installed in one of the plurality of mounting positions.

[0089] In this way, by adjusting the installation position of the industrial camera 510, the relative position of the laser projection image and the industrial camera 510 in the screen length direction Z of the receiving screen assembly can be adjusted, which is convenient for shooting laser projection images at different positions in the screen length direction Z of the receiving screen assembly.

[0090] The parallelism, perpendicularity, numerical values ​​and numerical ranges involved in the embodiments of the present application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.
