Description

Technical Field

[0001] The 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-proof 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 a high-strength, high-airtightness composite adhesive.

[0003] When producing insulating glass, spacers and colloids are needed to isolate single-layer glass. In order to distinguish product types, laser marking is generally required on 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 marking is prone to deviation during the marking process. After marking, other separate equipment is required to cut the super spacers after marking, which also has the problem of complicated operation. Summary of the invention

[0004] The main inventive concept of the present application is as follows: to provide an automatic laser marking device for super spacer bars for insulating glass, which can pre-press and flatten the spacer bars in a linked manner when the laser marking machine descends toward the spacer bars, and then perform laser engraving and marking, thereby improving the accuracy of the marking position, and after the marking is completed, the laser marking machine can shear the marked front spacer bars in a linked manner during the return process, thereby eliminating the operation process of separate cutting and improving the marking efficiency.

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, and after the marking is completed, the laser marking machine can return to its position and can drive the shearing mechanism to move in a linkage manner to cut the front spacer bars that have been marked, thereby eliminating the operation process of separate cutting and improving the marking efficiency.

[0007] As a preferred technical solution of the present application: the spacer strip conveying mechanism includes a traction roller and a driven roller rotatably connected to a bracket body, a conveying assembly is sleeved between the traction roller and the driven roller, and a drive motor is also provided on the bracket body, and the drive motor is connected to the traction roller through a synchronous belt drive.

[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. The spacer bar is set on the conveying assembly to realize transmission. For the convenience of control, the driving motor in this application adopts a servo motor, which can realize fixed-length conveying of the spacer bar.

[0009] As a preferred technical solution of the present application: the conveying assembly includes a conveyor belt sleeved between a traction roller and a driven roller, the conveyor belt is provided with a spacer bar positioning groove, and the spacer bar positioning groove includes a flat groove portion and a pointed groove portion arranged at the bottom of the flat groove portion. 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, wherein the flat groove portion can transport the flat spacer bar, and the pointed groove portion can be used to clamp the spacer bar with a pointed bottom, thereby improving its applicability.

[0010] As a preferred technical solution of the present application: the three-axis driving mechanism includes a Y-axis pushing member fixed on the top plate, the Y-axis pushing member is connected to a mounting block sliding on the upper side of the top plate, a Z-axis pushing member is installed on the mounting block, the telescopic rod of the Z-axis pushing member passes through the top plate and is connected to a mounting plate, an X-axis pushing member is arranged on the mounting plate, and the laser marking machine is installed on the mounting plate.

[0011] 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] 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 chute, the body generates a laser beam, and the laser beam is irradiated on the spacer through the laser beam gun to complete laser etching and marking.

[0014] As a preferred technical solution of the present application: the positioning and flattening mechanism includes an elastic pressing component provided on the mounting plate and a flattening component provided on the body, the elastic pressing component and the flattening component are on both sides of the laser beam gun and the elastic pressing component is on the front side of the feeding direction.

[0015] By adopting the above technical solution: at the beginning of marking, the mounting plate drives the body to move downward. During the downward movement of the mounting plate, the elastic pressing component is driven to first press one end of the spacer, and then after the mounting plate continues to move downward, the flattening component contacts the spacer. During marking, the elastic pressing component always presses the spacer, and then under the drive of the X-axis pusher, the laser beam gun moves along the length direction of the spacer for marking. Since the flattening component is provided on the body and is always on one side of the spacer to be marked, the spacer can be flattened first, and then the subsequent laser beam gun can perform marking, improving the accuracy of marking.

[0016] As a preferred technical solution of the present application: the elastic pressing component includes a cavity plate provided on the mounting plate and a pressing plate with one end passing through the inner side of the cavity plate, and a spring is provided between the pressing plate and the cavity plate.

[0017] By adopting the above technical solution: when the mounting plate descends, the end of the pressing plate first contacts the spacer. Due to the setting of the spring, the mounting plate can continue to drive the laser marking machine to descend, while the pressing plate forms a pressing on the spacer and does not affect the mounting plate to drive the laser marking machine to continue to approach the spacer.

[0018] As a preferred technical solution of the present application: the flattening component includes a connecting plate with one end fixed on the body, and 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.

[0019] By adopting the above technical solution: after the pressing plate presses the spacer, when the mounting plate continues to descend slightly, the elastic arc-shaped plate can also contact the spacer. During the marking process, the spacer can be flattened, thereby improving the accuracy of marking.

[0020] 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 provided 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.

The spacer is cleverly cut by using the process of the mounting plate returning, eliminating the process of cutting by other separate equipment and improving the efficiency of the entire production process.

[0022] 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, the yielding portion passes through the yielding cavity and is fixedly connected to the moving blade.

[0023] By adopting the above technical solution: the linkage rod is connected with the mounting plate, and the mounting plate can drive the linkage rod to rise and fall. When marking, the mounting plate descends, and the movable blade is driven to descend through the linkage rod, 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 yielding part, it can make way for the spacer bar in cooperation with the yielding cavity, so that the spacer bar can be located between the movable blade and the fixed knife groove, wherein the width of the yielding 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.

[0024] The working principle and beneficial effects of this application are: 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 driving 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 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 original position and can drive the shearing mechanism to move in a linked manner to cut the front spacer bars that have been marked, thereby eliminating the operation process of separate cutting and improving the marking efficiency.

[0025] 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 the flat spacer bar, and the pointed groove part can be used to clamp the spacer bar with a pointed bottom, which improves its applicability.

[0026] 3. At the beginning of marking, the installation plate drives the machine body to move downward. During the downward movement of the installation plate, the elastic pressing component is driven to first press one end of the spacer bar. Then, after the installation plate continues to move downward, the flattening component contacts the spacer bar. During marking, the elastic pressing component always presses the spacer bar. Then, driven by the X-axis pushing component, the laser beam gun moves along the length direction of the spacer bar for marking. Since the flattening component is arranged on the machine body and is always on one side of the spacer bar to be marked, the spacer bar can always be flattened first, and then the subsequent laser beam gun can perform marking, improving the accuracy of marking.

[0027] 4. After marking is completed, during the process of the installation plate returning to its original position, the moving blade can be driven to move towards the fixed knife groove through the linkage mechanism, and the spacer bar between the two is cut off. Cleverly using the process of the installation plate returning to its original position to cut the spacer bar saves the process of using separate other equipment for cutting, improving the efficiency of the entire production process.

[0037] Referring to Figure 1 , wherein, the three-axis drive 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. A Z-axis pusher 330 is mounted on the mounting block 320.

[0041] 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 first press one end of the spacer bar. Then, after the mounting plate 340 continues to move downward, the flattening component 520 contacts the spacer bar. During marking, the elastic pressing component 510 always presses the spacer bar. Then, driven by the X-axis pushing member 350, the laser beam gun 420 moves along the length direction of the spacer bar for marking. Since the flattening component 520 is disposed on the machine body 410 and is always on one side of the spacer bar to be marked, the spacer bar can be flattened first all the time, and then the subsequent laser beam gun 420 performs marking, improving the accuracy of marking.

[0042] Refer to Figure 3 , among which, the elastic pressing component 510 includes a cavity plate 511 disposed on the mounting plate 340 and a pressing plate 512 with one end penetrating inside the cavity plate 511. A spring 513 is provided between the pressing plate 512 and the cavity plate 511. When the mounting plate 340 descends, the end of the pressing plate 512 first contacts the spacer bar. Due to the setting of the spring 513, the mounting plate 340 can still drive the laser marking machine 400 to continue descending, while the pressing plate 512 forms a pressing on the spacer bar and does not affect the mounting plate 340 driving the laser marking machine 400 to continue approaching the spacer bar.

[0045] After marking is completed, during the process of the mounting plate 340 returning 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 off the spacer bar between the two. The process of the mounting plate 340 returning to its original position is cleverly utilized to cut off the spacer bar, eliminating the process of cutting by other separate equipment and improving the efficiency of the entire production process.

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.
