Description

Technical Field

[0001] The present invention relates to the technical field of laser marking equipment, and in particular to an automatic laser marking device for super spacer strips for insulating glass. Background Art

[0002] Insulating glass is a high-efficiency sound-insulating and heat-insulating glass made by bonding two (or three) pieces of glass to an aluminum alloy frame containing a desiccant using super spacer strips and high-strength and high-airtightness composite adhesives.

[0003] When producing insulating glass, single-layer glass needs to be separated by spacers and colloids. In order to distinguish product types, it is generally necessary to laser mark the spacers. The marking includes other information such as the overall size of the insulating glass, which is convenient for viewing product information during installation. Through research, we found that the existing laser marking equipment has inaccurate marking positions, and the marks are prone to deviation during the marking process. In addition, separate equipment is required to cut the marked super spacers after marking, which also has the problem of complicated operation. Summary of the Invention

When the laser marking machine descends, the spacer bars are pre-pressed by the positioning and flattening mechanism, and then the spacer bars can be pre-flattened during the marking process, thereby improving the accuracy of the marking position. After the marking is completed, the laser marking machine can return to its position and drive the shearing mechanism to move in a linked manner to cut the front spacer bars that have been marked, eliminating the operation process of separate cutting and improving the marking efficiency.

[0008] By adopting the above technical solution: the driving motor can drive the traction roller to rotate, and the traction roller drives the driven roller to rotate through the conveying assembly.

[0010] By adopting the above technical solution: during marking, the spacer bar is placed in the spacer bar positioning groove and transported by the conveyor belt. The flat groove part can transport flat spacer bars, and the pointed groove part can be used to clamp the spacer bar with a pointed bottom, thereby improving its applicability.

[0011] As a preferred technical solution of the present application: the three-axis driving mechanism includes a Y-axis pusher fixed on the top plate, the Y-axis pusher is connected to a mounting block sliding on the upper side of the top plate, a Z-axis pusher is installed on the mounting block, the telescopic rod of the Z-axis pusher passes through the top plate and is connected to a mounting plate, an X-axis pusher is provided on the mounting plate, and the laser marking machine is installed on the mounting plate.

[0012] By adopting the above technical solution: the Z-axis pusher can drive the mounting plate to move up and down, thereby driving the laser marking machine to move up and down, the X-axis pusher can drive the laser marking machine to move along the length direction of the spacer bar, and the Z-axis pusher can push the mounting block to make the mounting plate and the laser marking machine move along the width direction of the spacer bar, thereby facilitating the completion of laser marking.

[0013] As a preferred technical solution of the present application: a positioning groove is provided on the mounting plate, and the laser marking machine is slidably mounted on the mounting plate through the positioning groove. The X-axis pusher drives and connects the laser marking machine. The laser marking machine includes a body for forming a laser beam and a laser beam gun, and the laser beam gun is downward.

[0014] By adopting the above technical solution: the laser marking machine can be accurately slid under the push of the X-axis pusher through the positioning slide, the machine body generates a laser beam, and the laser beam gun is used to irradiate the spacer bar to complete the laser etching marking.

[0015] As a preferred technical solution of the present application: the positioning and flattening mechanism includes an elastic pressing component arranged on the mounting plate and a flattening component arranged on the machine body, the elastic pressing component and the flattening component are located on both sides of the laser beam gun and the elastic pressing component is located on the front side of the feeding direction.

[0016] By adopting the above technical solution: at the beginning of marking, the mounting plate drives the machine body to move downward, and during the downward movement of the mounting plate, the elastic pressing component is driven to press one end of the spacer bar first, and then the mounting plate continues to move downward and the flattening component contacts the spacer bar. When marking, the elastic pressing component always presses the spacer bar, and then, driven by the X-axis pusher, the laser beam gun moves along the length direction of the spacer bar for marking. Since the flattening component is set on the machine body and is always on the side of the spacer bar to be marked, the spacer bar can always be flattened first, and the laser beam gun at the back can be used for marking, thereby improving the accuracy of marking.

Due to the setting of the spring, the mounting plate can continue to drive the laser marking machine to descend, and the holding plate forms a pressure on the spacer bar without affecting the mounting plate driving the laser marking machine to continue to approach the spacer bar.

[0019] As a preferred technical solution of the present application: the flattening assembly includes a connecting plate fixed to the machine body at one end, an arc-shaped elastic plate is provided on the lower side of the connecting plate, and the inner arc of the arc-shaped elastic plate faces the laser beam gun.

[0020] By adopting the above technical solution: after the holding plate presses the spacer bar, the mounting plate continues to drop slightly, so that the elastic arc plate can also contact the spacer bar. During the marking process, the spacer bar can be flattened, thereby improving the marking accuracy.

[0021] As a preferred technical solution of the present application: the shearing mechanism includes a fixed knife block fixed on the bracket body, the fixed knife block is equipped with a fixed knife groove, and also includes a movable knife corresponding to the fixed knife groove and connected to the mounting plate through a linkage mechanism.

[0023] As a preferred technical solution of the present application: the linkage mechanism includes a linkage rod connected to the mounting plate, the linkage rod is provided with a yielding portion, the fixed blade block is provided with a yielding cavity, and the yielding portion is fixedly connected to the movable blade after passing through the yielding cavity.

[0024] By adopting the above technical solution: the linkage rod is connected to the mounting plate, and the mounting plate can drive the linkage rod to rise and fall. When marking, the mounting plate descends, and the linkage rod drives the movable blade to descend, and the movable blade does not contact the spacer bar. After the marking is completed, the mounting plate returns to its original position and drives the movable blade to gradually approach the spacer bar through the linkage rod and cooperate with the fixed knife groove to cut the spacer bar; by setting a give way part, it can cooperate with the give way cavity to give way to the spacer bar, so that the spacer bar can be located between the movable blade and the fixed knife groove, wherein the width of the give way cavity is equivalent to the width of the spacer bar, and does not hinder the movement of the mounting plate along the width direction of the spacer bar.

[0025] The working principle and beneficial effects of this application are:

[0026] 1. The bracket body in the present application is used to carry the device and install various mechanisms. The spacer bar conveying mechanism installed thereon is used to position and convey the super spacer bars of fixed length. The three-axis drive mechanism arranged on the top plate can drive the three-axis movement of the laser marking machine, which is convenient for laser marking of the super spacer bars. When the laser marking machine descends, the spacer bars are pre-pressed by the positioning and flattening mechanism. After that, the spacer bars can always be pre-flattened during the marking process, thereby improving the accuracy of the marking position. After the marking is completed, the laser marking machine can return to its position and drive the shearing mechanism to cut the front spacer bar that has been marked, thereby eliminating the operation process of separate cutting and improving the marking efficiency.

[0027] 2. Before marking, the spacer bar is placed in the spacer bar positioning groove and transported by the conveyor belt. The flat groove part can transport flat spacer bars, and the pointed groove part can be used to clamp the spacer bars with pointed bottoms, which improves its applicability.

[0028] 3. At the beginning of marking, the mounting plate drives the machine body to move downward. During the downward movement of the mounting plate, the elastic holding component is driven to hold one end of the spacer first. Then, the mounting plate continues to move downward and the flattening component contacts the spacer. During marking, the elastic holding component always holds the spacer. Then, driven by the X-axis pusher, the laser beam gun moves along the length direction of the spacer for marking. Since the flattening component is set on the machine body and is always on the side of the spacer to be marked, the spacer can always be flattened first, and then the laser beam gun is used for marking, which improves the accuracy of marking.

[0029] 4. After marking is completed, when the mounting plate returns to its original position, the linkage mechanism can drive the movable blade to move toward the fixed blade groove to cut the spacer between the two. The spacer is cut by cleverly utilizing the process of the mounting plate returning to its original position, eliminating the need for separate cutting equipment and improving the efficiency of the entire production process.

[0045] Reference Figure 1 Among them, the three-axis driving mechanism 300 includes a Y-axis pusher 310 fixed on the top plate 120, the Y-axis pusher 310 is connected to a mounting block 320 sliding on the upper side of the top plate 120, and a Z-axis pusher 330 is installed on the mounting block 320. The telescopic rod of the Z-axis pusher 330 passes through the top plate 120 and is connected to a mounting plate 340, and an X-axis pusher 350 is provided on the mounting plate 340. The laser marking machine 400 is installed on the mounting plate 340.

The Z-axis pusher 330 can drive the mounting plate 340 to move up and down, thereby driving the laser marking machine 400 to move up and down. The X-axis pusher 350 can drive the laser marking machine 400 to move along the length direction of the spacer bar. The Z-axis pusher 330 can push the mounting block 320 to move the mounting plate 340 and the laser marking machine 400 along the width direction of the spacer bar, thereby facilitating laser marking. A through groove should also be provided on the vertical plate 110, and the width of the through groove should be at least greater than the width of the spacer bar.

[0047] Reference Figure 1 In this embodiment, a positioning groove 341 is provided on the mounting plate 340. The laser marking machine 400 is slidably installed on the mounting plate 340 through the positioning groove 341. The X-axis pusher 350 drives the laser marking machine 400. The laser marking machine 400 includes a body 410 for forming a laser beam and a laser beam gun 420.

The elastic pressing component 510 and the flattening component 520 are located on both sides of the laser beam gun 420, and the elastic pressing component 510 is located on the front side in the feeding direction.

[0049] At the beginning of marking, the mounting plate 340 drives the machine body 410 to move downward. During the downward movement of the mounting plate 340, the elastic pressing component 510 is driven to press one end of the spacer bar first. Then, the mounting plate 340 continues to move downward and the flattening component 520 contacts the spacer bar. When marking, the elastic pressing component 510 always presses the spacer bar. Then, driven by the X-axis pusher 350, the laser beam gun 420 moves along the length direction of the spacer bar for marking. Since the flattening component 520 is set on the machine body 410 and is always on the side of the spacer bar to be marked, the spacer bar can always be flattened first, and the laser beam gun 420 at the back can be used for marking, thereby improving the accuracy of marking.

Due to the provision of the spring 513, the mounting plate 340 can continue to drive the laser marker 400 downward, while the holding plate 512 maintains pressure on the spacer bar without affecting the mounting plate 340's ability to drive the laser marker 400 toward the spacer bar.

[0053] After marking is completed, when the mounting plate 340 returns to its original position, the movable blade 630 can be driven by the linkage mechanism 700 to move toward the fixed blade groove 620 to cut the spacer between the two. The spacer is cut by cleverly utilizing the process of the mounting plate 340 returning to its original position, eliminating the need for separate cutting equipment and improving the efficiency of the entire production process.

[0055] The linkage rod 710 is connected to the mounting plate 340, and the linkage rod 710 can be driven to rise and fall through the mounting plate 340. When marking, the mounting plate 340 descends, and the movable blade 630 is driven to descend through the linkage rod 710, and the movable blade 630 does not contact the spacer bar. After the marking is completed, the mounting plate 340 returns to its original position and drives the movable blade 630 to gradually approach the spacer bar through the linkage rod 710 and cooperate with the fixed knife groove 620 to cut the spacer bar; by setting the yielding part 720, it can cooperate with the yielding cavity 730 to give way to the spacer bar, so that the spacer bar can be located between the movable blade 630 and the fixed knife groove 620, wherein the width of the yielding cavity 730 is equivalent to the width of the spacer bar, and does not hinder the mounting plate 340 from moving along the width direction of the spacer bar.
