Detailed Description
The application is described in further detail below with reference to fig. 1-5.
Referring to fig. 1, an embodiment of the application discloses a four-class library laser processing method, which comprises the following steps:
referring to fig. 2 and 3, step S1: firstly, assembling a steel block A and a steel block B, grabbing the steel block A by using steel block grabbing equipment, and moving the steel block A by the steel block grabbing equipment until the steel block A is placed at a processing position, and moving the steel block grabbing equipment back to the original position; and then the steel block grabbing equipment is used for grabbing the steel block B, the steel block grabbing equipment moves the steel block B, the steel block B is placed at the top end of the steel plate A, and at the moment, the steel block A and the steel block B are placed at the assembling position.
Specifically, in the embodiment of the application, the steel block A and the steel block B are steel blocks with an up-down assembly relationship, that is, after the four types of libraries are produced, the top ends of the steel block A and the bottom ends of the steel block B are mutually abutted. The placement is required to be performed according to the positional relationship among the steel blocks in the actual production process, and is not limited to the positional relationship described in the embodiment of the present application.
Referring to fig. 1 and 2, after the steel blocks a and B are placed in the assembled position, the steel blocks a and B are pushed using a steel block pushing device. In the embodiment of the application, the front plane 10 refers to the surface of the steel block A and the steel block B close to the assembly welding gap 3, the side plane 20 is one surface adjacent to the front plane 10, and the side plane 20 and the front plane 10 are mutually perpendicular. The steel block pushing equipment is provided with two groups of pushing components, each pushing component comprises a pushing plate and a hydraulic cylinder, and the hydraulic cylinders are used for driving the pushing plates to move. One of the push plates is abutted against the front plane 10 of the steel block A and the steel block B, and the other push plate is abutted against the side plane 20 of the steel block A and the steel block B.
After the steel block pushing equipment finishes pushing actions of the steel block A and the steel block B, the front plane 10 of the steel block A and the front plane 10 of the steel block B are positioned on the same plane, and the side plane 20 of the steel block A and the side plane 20 of the steel block B are positioned on the same plane; the welding edge of the steel block a is in the same plane as the welding edge of the steel block B, and the welding start point of the welding edge of the steel block a is the same as the welding start point of the welding edge of the steel block B, and the steel block a is aligned with the steel block B.
Step S2: after the steel block A is aligned with the steel block B, using a laser scanning imaging device to scan an assembly welding gap 3 between the steel block A and the steel block B; the laser scanning imaging device emits laser, the laser irradiates the front plane 10 of the steel block A and the steel block B and then is reflected, the laser scanning imaging device receives the reflected light, and an image is generated according to the received reflected light. After the laser scanning imaging device obtains the overall image of the fitting welding slit 3, the laser scanning imaging device outputs the scanned image to the image processing device.
Referring to fig. 3, specifically, when the laser scanning imaging device scans the fitting welding slit 3, the laser scanning imaging device moves along the length direction of the fitting welding slit 3, and the scanning surface of the laser scanning imaging device is parallel to the front surface 10 of the steel blocks a, B. And the laser scanning imaging equipment starts to move from the starting point of the welding edge of the steel block A and the steel block B, and when the laser scanning imaging equipment moves to the finishing point of the welding edge of the steel block A and the steel block B, the scanning action of the laser scanning imaging equipment is finished, and the whole image of the assembly welding gap 3 is generated.
Because the scanning surface of the laser scanning imaging device is parallel to the front plane 10 of the steel block A and the steel block B, when the laser scanning imaging device generates images, the influence of the inclination angle between the scanning surface of the laser scanning imaging device and the front plane 10 of the steel block A and the steel block B on imaging is reduced, and the step of correction calculation according to the inclination angle in the imaging process is further reduced. As the step of inclination correction calculation is reduced, the imaging speed of the laser scanning imaging equipment is increased, and the time for processing four types of libraries by laser is further saved.
When the whole image of the assembly welding slit 3 is acquired, the laser scanning imaging device irradiates the whole assembly welding slit 3 with laser light. When the laser scanning imaging device is positioned at the starting point of the welding edge of the steel block A and the steel block B, the laser scanning imaging device starts to move after acquiring the starting point image of the assembly welding gap 3. Because the laser scanning imaging device moves along the length direction of the assembly welding gap 3, the assembly welding gap 3 is always in the scanning range of the laser scanning imaging device, so that the laser scanning imaging device can grasp the shape of the assembly welding gap 3. The situation that the laser scanning imaging equipment moves around to search for the assembly welding gap 3 is reduced, and the speed of overall imaging of the assembly welding gap 3 is further improved.
Step S3: the image processing device receives the image from the laser scanning imaging device, analyzes the received image and finally obtains a cutting image; the image processing device outputs the cut image obtained by analysis to the laser cutting device.
In particular, the image processing apparatus is optionally but not limited to a computer. The image processing device will analyze the image scanned by the laser scanning imaging and extract the image of the fitting welding seam 3. The fitting welding slit 3 is a portion of the image that is free, that is, a portion of the image that is low in brightness, is an image of the fitting welding slit 3. The image processing apparatus separates the outline of the portion of the image having lower brightness to obtain the outline of the fitting welding slit 3.
Further, the laser scanning imaging device synchronously outputs the scanned image to the image processing device in the process of scanning the assembly welding gap 3; that is, when the laser scanning imaging device performs the work of scanning the fitting welding slit 3, the image processing device simultaneously parses the scanned image. The laser scanning imaging device and the image processing device work synchronously, so that the total time for generating cutting images is saved, and the laser processing efficiency is further improved.
Step S4: after the image processing device outputs the cutting image to the laser cutting device, the laser cutting device moves according to the contour of the received cutting image, and meanwhile the laser cutting device performs the action of cutting the steel plate raw material 7; until the matched steel plate 4 with the same shape as the cutting image is cut, the cutting action of the laser cutting device is completed, and the laser cutting device returns to the original position.
Referring to fig. 2 and 4, the cut image is the contour of the assembly welding seam 3 of the steel block a and the steel block B, specifically, the upper contour edge 5 of the contour of the assembly welding seam 3 is the welding edge of the steel block B, and the lower contour edge 6 of the contour of the assembly welding seam 3 is the welding edge of the steel block a. When the laser cutting device cuts the upper contour edge 5, the laser cutting device moves along the upper contour edge 5 from the welding edge starting point of the steel block B until the upper contour edge 5 moves to the welding edge finishing point of the steel block B, and then the upper contour edge 5 of the contour of the assembly welding seam 3 is cut. Similarly, when the laser cutting device cuts the lower contour edge 6, the laser cutting device moves along the lower contour edge 6 from the welding edge starting point of the steel block a until the lower contour edge 6 moves to the welding edge finishing point of the steel block a, and then the lower contour edge 6 of the contour of the assembly welding gap 3 is cut. The distance between the upper contour edge 5 and the lower contour edge 6 is the width of the assembly welding gap 3.
Referring to fig. 4, the upper end of the steel plate raw material 7 is a cutting pitch block 8, and specifically, the cutting pitch block 8 is located above the upper contour edge 5. The cutting spacing block 8 is a blank space of the steel plate raw material 7, and the cutting spacing block 8 is arranged, so that when the laser cutting equipment moves along the outline of a cutting image, laser emitted by the laser cutting equipment irradiates the steel plate raw material 7, and the occurrence of the condition that the laser emitted by the laser cutting equipment damages other objects is reduced.
Referring to fig. 4 and 5, further, both ends of the steel plate raw material 7 are gripping spaces; when the laser cutting work is carried out, the laser cutting equipment moves along the length direction of the steel plate raw material 7 until the moving distance of the laser cutting equipment is equal to the length of the holding space; at this time, the laser cutting device moves to the welding edge end point of the steel block B along the upper contour edge 5, then moves along the length direction of the steel plate raw material 7 until the moving distance is equal to the length of the holding space, at this time, the cutting work of the laser cutting device cutting the upper half part of the matched steel plate 4 is completed, and the cutting spacing block 8 is separated from the steel plate raw material 7. The cutting operation of the laser cutting device to cut the lower half portion of the mating steel plate 4 is the same as that of the upper end, and will not be described here again. The finished product obtained by cutting by the final laser cutting equipment is a matched steel plate 4 and gripping blocks 9 at two ends, and the gripping blocks 9 at two ends are fixedly connected with the matched steel plate 4.
Step S5: two gripping blocks 9 are simultaneously gripped by using the steel plate gripping device, and since both gripping blocks 9 are fixedly connected with the mating steel plate 4, the mating steel plate 4 is gripped. The steel plate gripping equipment moves the matched steel plate 4 until the matched steel plate 4 is inserted into the assembly welding gap 3 between the steel blocks A and B, and then the matched steel plate 4 is moved.
Referring to fig. 5, in particular, the steel plate gripping apparatus may be, but is not limited to, a robot or the like; during the movement of the mating steel plate 4, the steel plate gripping device grips the gripping blocks 9 at both ends of the mating steel plate 4. The matched steel plate 4 is kept in a tight state in the moving and assembling process, the situation that the matched steel plate 4 is bent under the influence of gravity is reduced, and the matched steel plate 4 is convenient to insert into the assembling and welding gap 3 between the steel blocks A and B.
Further, during the operation of the laser cutting device cutting the lower half of the mating steel plate 4, the laser cutting device is moved along the length direction of the steel plate raw material 7; when the distance traveled by the laser cutting device is equal to the length of the gripping space, the steel plate gripping device grips the gripping block 9, which has been cut. The situation that the matched steel plate 4 falls under the influence of gravity in the working process of cutting the lower half part of the matched steel plate 4 by the laser cutting equipment is reduced. When the work of the laser cutting device cutting the lower half of the mating steel plate 4 is completed, the steel plate gripping device grips the other gripping block 9.
Step S6: when the mating steel plate 4 is inserted into the assembly welding gap 3, one side of the mating steel plate 4 is welded with the welding edge of the steel block B by using a laser welding device, and the other side of the mating steel plate 4 is welded with the welding edge of the steel block A by using the laser welding device.
The laser welding equipment is provided with the inert gas injection component, the inert gas injection component injects inert gas in the laser welding process, the condition of oxidation of a molten pool in the welding process is reduced, and the welding effect is improved. Specifically, before the matched steel plate 4 is welded with the steel block A and the steel block B, cleaning equipment is used for cleaning the front plane 10 of the matched steel plate 4, the steel block A and the steel block B, and the occurrence of the condition that the effects of laser welding are affected by greasy dirt, scraps and the like on the surfaces of the matched steel plate 4, the steel block A and the steel block B is reduced. The cleaning device is optionally, but not limited to, a laser washer. Further, after the mating steel plate 4 is welded with the steel blocks a and B, the gripping blocks 9 at both ends of the mating steel plate 4 are cut by a laser cutting device until the gripping blocks 9 are separated from the mating steel plate 4, and at this time, the cutting operation is completed.
Step S7: and (3) repeating the steps S1-S6, and welding the steel blocks for the four types of libraries to the corresponding positions one by one until the four types of libraries are assembled.
Specifically, when the width of the assembly welding gap 3 between two steel blocks is 0 mm < x is less than or equal to 1 mm, the gap between the two steel blocks meets the laser welding condition, and the auxiliary welding of a filling steel plate is not needed. And when the laser scanning imaging equipment is used for scanning the width of the assembly welding gap 3 between the two steel blocks in the step S2, if the value of the width of the assembly welding gap 3 between the two steel blocks is 0 mm < x is less than or equal to 1 mm, the steps S3-S5 are skipped, and the two steel blocks are directly welded by the laser welding equipment.
The implementation principle of the embodiment of the application is as follows: stacking and placing two steel blocks for producing four types of libraries, and scanning the shape of an assembly welding gap 3 between the two steel blocks by using laser scanning imaging equipment; manufacturing a matched steel plate 4 for filling the assembly welding gap 3 by using laser cutting equipment according to the shape of the scanned assembly welding gap 3; the matching steel plate 4 is inserted into the assembly welding gap 3 between the two steel blocks, so that the gap between the two steel blocks is narrowed, the effect of reducing welding seams is achieved, the success rate of laser welding is improved, and the production cost of four types of libraries is reduced.
