Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser cleaning, and specifically discloses an automatic laser cleaning device. BACKGROUND

[0002] Laser cleaning is a method that uses the high energy density of laser to interact with the pollutants attached to the workpiece base, causing them to expand, melt, and gasify instantaneously, and thus separate from the workpiece base. Compared with traditional chemical cleaning and mechanical cleaning, laser cleaning has the characteristics of no grinding, non-contact, no thermal effect, and suitability for various materials, and is considered the most reliable and effective solution. Laser cleaning is also highly efficient, environmentally friendly, and energy-saving, and is widely used in tire mold cleaning, aircraft body paint removal, and metal rust removal.

[0003] For example, patent CN114345837B, published on August 16, 2024, discloses a laser cleaning device that includes a workbench, a clamping device, and a cleaning device. The clamping device is located on the workbench and includes a clamp for clamping the workpiece and a first drive element, which is a variable speed drive device. A laser is used to generate a laser beam. The laser head is connected to the laser through an optical fiber. The focusing device includes a first housing and a focusing mirror, and the laser head is connected to one side of the first housing. The cleaning head includes a first housing and a mirror, and the first housing is connected to the side of the first housing away from the laser head. The mirror surface of the mirror and the axis of the focusing mirror form a set angle. At least two of the clamping device, the focusing device, and the cleaning head can move in the direction of the workpiece towards the cleaning head. The first drive element drives the workpiece to rotate at different speeds, so that the movement speed of the laser on the cavity wall is the same when cleaning different diameter cavity walls, and the cleaning effect of different diameter cavity walls is the same.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0030] As shown in Figures 1-7 The automatic laser cleaning device provided by the embodiment of the present application comprises a workbench 1, a laser cleaning head 2 is installed on the workbench 1, and a rotating support assembly 3 is symmetrically arranged on the workbench 1. The rotating support assembly 3 supports the cylindrical workpiece and keeps the workpiece in a horizontal state. The laser cleaning head 2 is driven to move horizontally along the axial direction of the workpiece. The rotating support assembly 3 drives the workpiece to rotate intermittently so that the side wall of the workpiece is fully cleaned.

[0031] Specifically, the cleaning device is mainly used for laser cleaning of cylindrical workpieces with large size and weight. The main structure is a workbench 1. A laser cleaning head 2 is installed on the workbench 1. The laser cleaning head 2 comprises a laser and an optical system (lenses, mirrors and optical fibers, etc.). The laser and the optical system are both prior art and can be directly applied without further description. The rotating support assembly 3 is also symmetrically installed on the workbench 1. Figure 1As shown, the symmetrically arranged rotating support assembly 3 is used to support the cylindrical workpiece and keep the central axis of the workpiece in a horizontal state, and the symmetry plane of the rotating support assembly 3 has a support station along the length direction of the workbench 1; optionally, the rotating support assembly 3 comprises a plurality of support rollers 32 rotatably mounted on the workbench 1, each support roller 32 is arranged along the length direction of the workbench 1, and the central axes of the support rollers 32 on the same side of the support station coincide, so that when the cylindrical workpiece is hoisted to the support station, the cross sections of the two groups of support rollers 32 on both sides of the support station and the workpiece form a "pin" shape, thereby stably supporting the workpiece; in this embodiment, the laser cleaning head 2 is installed above the support station through the support piece 4, and the workbench 1 is also provided with a linear driving mechanism for driving the support piece 4 to move along the length direction of the workbench 1, and the linear driving mechanism is used to drive the support piece 4 to reciprocate along the length direction of the workbench 1, which is a prior art and can be directly applied without further description. In addition, the workbench 1 is also provided with a rotating driving member such as a motor for driving the support rollers 32 on one side of the support station to rotate synchronously; obviously, in order to ensure the automatic operation of the device, the workbench 1 is also provided with a control system and a dust removal device, and the control system and the dust removal device are prior arts and can be directly applied without further description.

[0032] During laser cleaning, the cylindrical workpiece is hoisted to the support station and supported by the support rollers 32 on both sides of the support station, as shown in the figure Figure 1 As shown, after the workpiece is placed stably, the laser cleaning head 2 is started, and the laser cleaning head 2 is driven to move along the length direction of the workbench 1, that is, the axial direction of the workpiece, from above one end of the workpiece to above the other end of the workpiece, in this process, the laser emitted by the laser cleaning head 2 cleans the rust on the surface of the workpiece, and when the laser cleaning head 2 moves to above the other end of the workpiece, it is temporarily stopped, and the support rollers 32 on one side (or both sides) of the support station are driven to rotate synchronously and in the same direction. When the support rollers 32 rotate, they drive the workpiece to rotate by a certain angle through the friction between the support rollers 32 and the workpiece, so as to rotate the surface of the workpiece that has not been cleaned to be directly below the laser cleaning head 2, and then the laser cleaning head 2 is driven to move reversely from above the other end of the workpiece to above one end of the workpiece, and the angle of the workpiece is adjusted by driving the support rollers 32 to rotate, and the process is repeated until the outer side wall of the workpiece is completely cleaned.

[0033] The laser cleaning device provided by the embodiment of the application can support a cylindrical workpiece with large size and heavy weight through the symmetrically arranged rotating support assemblies 3 on the workbench 1, and the cooperation of the two rotating support assemblies 3 can support the cylindrical workpiece, and the workpiece can be driven to rotate by the rotation of the support rollers 32 in the rotating support assembly 3 to adjust the angle of the workpiece, so that the side surface of the workpiece can be completely cleaned, and the efficiency is higher and the method is more environmentally friendly compared with the existing sand blasting method.

[0034] Further, the rotating supporting assembly 3 comprises supporting seats 31 symmetrically mounted on the workbench 1, supporting stations are formed between the supporting seats 31, and a plurality of groups of the supporting seats 31 are arranged along the length direction of the workbench 1, each of the supporting seats 31 is rotationally mounted with a supporting roller 32, and each of the supporting rollers 32 is horizontally arranged along the length direction of the workbench 1.

[0035] Specifically, at least two groups of the supporting seats 31 are arranged along the length direction of the workbench 1, each of the supporting rollers 32 is correspondingly arranged with the supporting seat 31, and each of the supporting rollers 32 is rotationally mounted on the corresponding supporting seat 31, and each of the supporting rollers 32 is horizontally arranged along the length direction of the workbench 1, so that the workpiece can be stably supported during the cleaning process.

[0036] Further, each of the supporting seats 31 is slidingly mounted on the workbench 1, and each of the supporting seats 31 slides along the width direction of the workbench 1, and each of the supporting seats 31 is further provided with a locking piece 5, and the locking piece 5 is used to lock the corresponding supporting seat 31 on the workbench 1.

[0037] Specifically, in the production process, the diameters of the steel pipes and round steels are various, and the positions of the supporting rollers 32 on both sides of the supporting station are fixed, so that the supporting rollers 32 can support the workpieces with different diameters within a certain range, but when the diameter of the workpiece is large, the workpiece can be supported, but when the supporting roller 32 supports the workpiece, the point of the supporting roller 32 in contact with the side surface of the workpiece is close to the lowest point of the workpiece in the gravity direction, so that the stability of the workpiece during the rotation in the cleaning process cannot be guaranteed, and when the diameter of the workpiece is small, the point of the supporting roller 32 in contact with the side surface of the workpiece is close to the middle part of the workpiece in the gravity direction, so that it is difficult to drive the workpiece to rotate by the friction between the supporting roller 32 and the workpiece; in the embodiment, each of the supporting seats 31 is slidingly mounted on the workbench 1, and each of the supporting seats 31 slides along the width direction of the workbench 1, so that the distance between the two groups of the supporting rollers 32 on both sides of the supporting station can be adjusted, thereby adapting to the workpieces with different diameters, ensuring that the workpiece is stably supported, and ensuring that the friction between the workpiece and the supporting roller 32 is sufficient to drive the supporting roller 32 to rotate the workpiece; in addition, each of the supporting seats 31 is further provided with the locking piece 5, and the locking piece 5 can lock the supporting seat 31 on the workbench 1, so as to ensure that the supporting seat 31 cannot slide relative to the workbench 1 during the cleaning process of the workpiece, and optionally, the locking piece 5 is a bolt, and the workbench 1 is provided with a screw hole matched with the bolt, and each of the supporting seats 31 is locked at different positions on the workbench 1 by the bolt.

[0038] The diameters of the workpieces are different, so that the distance between the laser cleaning head 2 and the highest point of the workpiece in the gravity direction changes, in order to ensure that the laser cleaning head 2 and the workpiece can always maintain the best cleaning distance, the workbench 1 is provided with another linear driving mechanism for adjusting the height of the laser cleaning head 2, in the embodiment, the supporting member 4 is in the shape of “Z”, which comprises a base 41, a vertical rod 42 and a horizontal rod 43, as shown inFigure 1 As shown, the base 41 is slidingly mounted on the workbench 1 and slides along the length direction of the workbench 1, the vertical rod 42 is fixedly mounted on the base 41 near one side of the supporting station, the horizontal rod 43 is slidingly mounted on the upper end of the vertical rod 42 and extends above the supporting station, preferably, the vertical rod 42 is a telescopic rod, the vertical rod 42 is provided with a driving member such as an electric push rod (not shown in the figure) for driving the horizontal rod 43 to slide up and down, the base 41 is fixedly mounted with a motor, the output end of the motor is fixedly connected with a gear, the workbench 1 is provided with a rack along the length direction of the workbench 1, the gear is engaged with the rack, so that when the motor drives the gear to rotate, the base 41 can be driven to move along the length direction of the workbench 1.

[0039] In order to facilitate the unlocking of the supporting seat 31 to adjust the position of the supporting seat 31 on the workbench 1, the locking member 5 comprises a plug-in pin 51 slidingly mounted on the supporting seat 31, and the workbench 1 is provided with a plug-in hole 11 matched with the plug-in pin 51, preferably, the plug-in pin 51 slides in the vertical direction, i.e. the height direction of the workbench 1, and the workbench 1 is vertically provided with the plug-in hole 11 matched with the plug-in pin 51, and the sliding plug-in pin 51 is inserted into the plug-in hole 11 to limit the position of the supporting seat 31.

[0040] In another embodiment of the present application, the supporting seat 31 is movably mounted with a supporting frame 33, and the supporting roller 32 is rotatably mounted on the supporting frame 33, and the supporting seat 31 is further provided with a buffer assembly for buffering the supporting frame 33.

[0041] Specifically, since the steel pipe and round steel are heavy, they are usually hoisted for feeding, and the impact of the workpiece on the supporting roller 32 during hoisting is easy to cause damage to the supporting roller 32 itself and the connecting part between the supporting roller 32 and the supporting seat 31; in the present embodiment, the supporting seat 31 is movably mounted with a supporting frame 33, which is slidingly mounted on the supporting seat 31 and slides in the vertical direction, and the supporting roller 32 is rotatably mounted on the supporting frame 33, in addition, the supporting seat 31 is further provided with a buffer assembly, the sliding of the supporting frame 33 on the supporting seat 31 provides a certain stroke for the buffering of the buffer assembly, thereby protecting the supporting roller 32 and the connecting part between the supporting roller 32 and the supporting seat 31, and the buffer assembly is a hydraulic buffer rod 34 mounted on the supporting seat 31, one end of the hydraulic buffer rod 34 away from the supporting seat 31 is connected with the supporting frame 33, in the present embodiment, since the supporting frame 33 is slidingly connected with the supporting seat 31 and slides in the vertical direction, the hydraulic buffer rod 34 is vertically arranged, and one end of the hydraulic buffer rod 34 is fixedly connected with the supporting seat 31, and the other end of the hydraulic buffer rod 34 is fixedly connected with the supporting frame 33.

[0042] Further, the support frame 33 is V-shaped, and the support frame 33 is rotationally installed on the support base 31, and two groups of support rollers 32 are rotationally installed on each support frame 33, the two support rollers 32 are parallel, and the two support rollers 32 are arranged along the length direction of the workbench 1, and the two ends of the hydraulic buffer rod 34 are rotationally connected with the support base 31 and the workbench 1 respectively.

[0043] Specifically, in the above embodiment, when the support base 31 is fixed, the distance between the support rollers 32 on both sides of the support station is determined, so that when the diameter of the workpiece changes (the diameter changes a little, such as from 80mm to 100mm), the position of the support base 31 needs to be adjusted to change the distance between the two support rollers 32, so as to achieve the best support of the workpiece; in this embodiment, the support frame 33 is V-shaped, as shown in Figures 4 to 7 , the support frame 33 is rotationally connected with the support base 31, and the support frame 33 includes two parallel V-shaped frames 331 and a rotating shaft 332 connecting the two V-shaped frames 331, the rotating shaft 332 is rotationally installed on the support base 31, for the convenience of description, the V-shaped frame 331 includes two end points at the opening position and an intermediate point at the bottom, and the two ends of the rotating shaft 332 are connected with the corresponding intermediate points of the V-shaped frame 331; in addition, two groups of support rollers 32 are rotationally installed on the support frame 33, the two support rollers 32 are parallel, the two ends of one group of support rollers 32 are rotationally connected with the opposite end points of the two groups of V-shaped frames 331, and the two ends of the other group of support rollers 32 are rotationally connected with the opposite end points of the two groups of V-shaped frames 331, and all the support rollers 32 are arranged along the length direction of the workbench 1, because the support frame 33 is rotationally installed on the support base 31, so in this embodiment, one end of the hydraulic buffer rod 34 is rotationally installed on the support base 31, and the other end of the hydraulic buffer rod 34 is rotationally connected with the side of the V-shaped frame 331 close to the end point.

[0044] In the rotation stroke of the support frame 33, there is an initial angle, as shown in Figure 5 , when the initial angle, the opening of the two V-shaped frames 331 is inclined towards the above-mentioned support station, preferably, the opening of the V-shaped frame 331 is between 60°-75° with the horizontal direction, and the end of the hydraulic buffer rod 34 away from the support base 31 is rotationally connected with the lower side of the V-shaped frame 331 and the position close to the end point on the side, so that when the support frame 33 rotates, the hydraulic buffer rod 34 is mainly stressed, thereby improving the buffering effect of the hydraulic buffer rod 34, and at the same time, reducing the stress of the rotating shaft 332 in the support frame 33, so as to avoid damage to the rotating shaft 332.

[0045] In the process of hoisting the workpiece, the support frames 33 on both sides of the support station are in the initial state, at this time, the opening of the V-shaped frame 331 has the largest angle with the horizontal direction, so the support frames 33 on both sides of the support station have a larger supporting range, and the workpiece is allowed to have a larger deviation during hoisting to the support station, and the workpiece first contacts the support rollers 32 on the support frames 33 on both sides of the support station (only one group of support rollers 32 on the support frames 33 on both sides of the support station is in contact with the workpiece), for the convenience of description, the support roller 32 on the support frame 33 on the side close to the support station is the first roller 321, and the other support roller 32 on the support frame 33 on which the first roller 321 is located is the second roller 322, the workpiece first contacts the first roller 321 during hoisting, and as the workpiece slowly falls, the pressure of the workpiece on the first roller 321 drives the support roller 32 to rotate the support frame 33, at this time, the second roller 322 on the support frame 33 gradually approaches the side wall of the workpiece until it is in contact with the side wall of the workpiece, in this process, the hydraulic buffer rod 34 is retracted and slows down the rotation trend of the support frame 33, until the workpiece is stably placed.

[0046] By rotatingly connecting the V-shaped support frame 33 with the support seat 31, and rotatingly installing two groups of support rollers 32 on each support frame 33, on the one hand, the support frames 33 on both sides of the support station increase the size range of the workpiece, and when the angle and position of the workpiece have a small deviation during hoisting, the position of the workpiece can be automatically calibrated by the rotation of the support frame 33; on the other hand, the V-shaped support frame 33 itself forms a lever, when the first roller 321 on the support frame 33 is subjected to the gravity of the workpiece, it will make the support frame 33 have a downward rotation trend, thereby pressing the second roller 322 on the support frame 33 towards the workpiece, thereby increasing the friction between the second roller 322 and the workpiece; further, the hydraulic buffer rod 34 is directly connected with the position close to the end point of one side of the V-shaped frame 331 (the side on which the first roller 321 is installed), during hoisting of the workpiece until it is stably placed, the total weight of the workpiece is mainly borne by the hydraulic buffer rods 34, so as to protect the rotating shaft 332 connected with the support seat 31 on the support frame 33 from being damaged.

[0047] In still another embodiment of the present application, the workbench 1 is provided with a positioning assembly 6 for adjusting the position of the workpiece so that the workpiece can be hoisted to directly above the support station.

[0048] Further, the positioning assembly 6 includes two groups of parallel and vertically arranged positioning plates 61, the positioning plates 61 are on both sides of the support station, and the two positioning plates 61 are driven to move towards each other to calibrate the position of the workpiece.

[0049] Specifically, in the above embodiment, by setting the support frame 33 to be V-shaped, and rotatingly installing the first roller 321 and the second roller 322 on each support frame 33, although the deviation of the workpiece during hoisting can be calibrated within a certain range, the deviation of the workpiece is too large during hoisting of the workpiece, which is caused by the position deviation of the hoisting belt bound on the workpiece and the movement of the hoisting equipment driving the workpiece, so that one end of the workpiece is completely outside the position that can be calibrated by the support roller 32, that is, the workpiece cannot be positionally calibrated by rotating the support frame 33. At this time, the angle of the workpiece is usually adjusted manually, however, manual adjustment is relatively dangerous and has safety hazards; in the embodiment, the workbench 1 is also provided with a positioning assembly 6, which can adjust the position of the workpiece so that the workpiece can be positioned directly above the support station, as shown in Figures 1 to 4 The positioning assembly 6 includes two groups of positioning plates 61 arranged in parallel and vertically, the positioning plates 61 are arranged on both sides of the support station, and the two positioning plates 61 are driven to move towards each other, so that the workpiece can be positioned above the support station by clamping. At this time, the workpiece can be placed directly downward along the vertical direction. In the figure, the positioning assembly 6 is arranged on the workbench 1 at a position corresponding to the middle of the support station, that is, the two positioning plates 61 clamp the middle part of the workpiece. The workbench 1 is provided with two groups of horizontally arranged air cylinders 62, and the two groups of positioning plates 61 are fixedly connected to the output ends of the corresponding air cylinders 62.

[0050] In another embodiment of the present application, the adjacent two support seats 31 on the same side of the support station on the workbench 1 are connected by a connecting rod 35, and the connecting rod 35 corresponding to the positioning plate 61 is detachably connected to the positioning plate 61.

[0051] Specifically, since the number of support seats 31 is large, when the diameter of the workpiece to be cleaned changes greatly and the distance between the support seats 31 on both sides of the support station needs to be adjusted, each support seat 31 needs to be adjusted, which is inconvenient to operate and easy to cause inconsistent adjustment of each support seat 31. In the embodiment, the adjacent two support seats 31 on the same side of the support station on the workbench 1 are connected by a connecting rod 35, so that the support seats 31 on the same side of the support station on the workbench 1 are connected into a whole by the connecting rod 35 and can be adjusted synchronously. In addition, the connecting rod 35 corresponding to the positioning plate 61 is detachably connected to the positioning plate 61. Alternatively, Figure 4As shown, the position of the positioning plate 61 corresponding to the connecting rod 35 is horizontally protruded above the connecting rod 35, and the protruding position of the positioning plate 61 and the corresponding position on the connecting rod 35 are both provided with a pin hole 611, by installing a pin shaft 612 in the pin hole 611, the positioning plate 61 and the corresponding connecting rod 35 can be connected as a whole, so as to pull the positioning plate 61 by the above-mentioned cylinder 62, so that the positioning plate 61 drives each support seat 31 on the same side (the side where the positioning plate 61 is located) of the support station on the workbench 1 to slide synchronously, the adjustment efficiency is high, and the adjustment amount of each support plate is consistent; in this embodiment, the positioning plate 61 can not only position the position of the workpiece, but also adjust the position of each support seat 31 on the same side of the support station.

[0052] Further, the locking piece 5 has two states of limiting and locking for the support seat 31, when the support frame 33 is pressed to rotate by the workpiece, the locking piece 5 is driven to switch from the limiting state to the locking state.

[0053] Specifically, in the above embodiment, the locking piece 5 needs to be manually unlocked, but since the number of support seats 31 is large, the operation is relatively inconvenient; in this embodiment, the locking piece 5 has two states of limiting and locking, when in the limiting state, it can only limit the position of the support seat 31 on the workbench 1, but when the support seat 31 is forced to a certain extent, it can also slide on the workbench 1, that is, when the locking piece 5 is in the limiting state, each support seat 31 can be pulled to slide synchronously on the workbench 1 by the positioning plate 61, and when the locking piece 5 is in the locking state, the positioning plate 61 cannot pull the support seat 31 to slide; as Figure 5 and Figure 6 As shown, the plug-in pin 51 is a square rod, the plug-in pin 51 is vertically installed on the support seat 31, and the plug-in pin 51 penetrates the support seat 31, the workbench 1 is provided with a plug-in hole 11 matched with the plug-in pin 51, the lower end of the plug-in pin 51, that is, the end matched with the plug-in hole 11, is isosceles trapezoidal, in addition, the support seat 31 is also provided with a spring 52 for maintaining the relative position of the plug-in pin 51 and the support seat 31, the spring 52 is sleeved on the part of the plug-in pin 51 above the support seat 31, the upper end of the plug-in pin 51 is fixedly connected with a pressing plate 53, when the spring 52 is in a natural state, the end of the plug-in pin 51 is partially inserted into the plug-in hole 11, the support frame 33 is fixedly connected with an arc-shaped plate 36, as Figure 5 and Figure 6 As shown, the center axes of the arc-shaped plate 36 and the support frame 33 are in the same horizontal plane, and the center axes of the two are staggered, so that during the rotation of the arc-shaped plate 36 with the support frame 33, the arc-shaped plate 36 can be pushed downward by the pressing plate 53 with the change of the contact position of the outer wall of the arc-shaped plate 36 and the pressing plate 53.

[0054] When the locking piece 5 is in the limiting state, as Figure 5As shown, the spring 52 is in a natural state, at this time, the lower end of the plug-in pin 51 is inserted into the plug-in hole 11, at this time, the support seat 31 is pulled by the positioning plate 61, the inclined surface of the lower part of the plug-in pin 51 is in contact with the end of the plug-in hole 11, and the plug-in pin 51 is blocked by the plug-in hole 11 and moves upward, thereby automatically changing from the limiting state to the unlocking state, and when the support seat 31 is under a small force, the plug-in pin 51 cannot be moved upward to release the limiting of the support seat 31.

[0055] As shown, the spring 52 is in a natural state, at this time, the lower end of the plug-in pin 51 is inserted into the plug-in hole 11, at this time, the support seat 31 is pulled by the positioning plate 61, the inclined surface of the lower part of the plug-in pin 51 is in contact with the end of the plug-in hole 11, and the plug-in pin 51 is blocked by the plug-in hole 11 and moves upward, thereby automatically changing from the limiting state to the unlocking state, and when the support seat 31 is under a small force, the plug-in pin 51 cannot be moved upward to release the limiting of the support seat 31. Figure 6 As shown, the spring 52 is in a natural state, at this time, the lower end of the plug-in pin 51 is inserted into the plug-in hole 11, at this time, the support seat 31 is pulled by the positioning plate 61, the inclined surface of the lower part of the plug-in pin 51 is in contact with the end of the plug-in hole 11, and the plug-in pin 51 is blocked by the plug-in hole 11 and moves upward, thereby automatically changing from the limiting state to the unlocking state, and when the support seat 31 is under a small force, the plug-in pin 51 cannot be moved upward to release the limiting of the support seat 31.

[0056] In the embodiment, the arc-shaped plate 36 is installed on the support frame 33, and the locking of the plug-in pin 51 to the support seat 31 is divided into two states, when the support frame 33 is pressed by the workpiece and rotates, the plug-in depth of the plug-in pin 51 in the plug-in hole 11 can be adjusted by the arc-shaped plate 36, thereby switching the locking state from the limiting state to the locking state, that is, only when the support clamp is placed with the workpiece, the support seat 31 is switched to the locking state, thereby avoiding the tedious operation of manually unlocking the support seat 31 when adjusting the position of the support seat 31.

[0057] Further, the plug-in pin 51 is provided with a sensor (the sensor is arranged between the spring 52 and the plug-in pin 51), and the sensor is a pressure sensor, when the end of the plug-in pin 51 is continuously inserted into the plug-in hole 11 of the workbench 1 from the position of the limiting state, the spring 52 changes from the natural state to the compressed state, thereby changing the reading of the pressure sensor, the pressure sensor feeds back the measurement data to the control system of the cleaning device, and the control system controls the contraction of the air cylinder 62, so that the air cylinder 62 pulls the corresponding positioning plate 61 away from the workpiece, and the positioning plate 61 is reset, thereby avoiding the damage of the positioning plate 61 caused by the laser irradiation.

[0058] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
