Description

Technical Field

[0001] The invention relates to the field of automobile plate processing, in particular to an automobile plate laser welding blanking mechanism. Background Art

[0002] Laser welding is an important process in the processing of automotive sheet metal. With the development of technology, some automated sheet metal laser welding blanking devices have emerged in the existing technology. For example, the patent with authorization announcement number CN218988081U discloses a product blanking device for a laser production line, which includes a blanking robot, and the execution end of the blanking robot is equipped with a transfer fixture. The suction cup assembly on the transfer fixture can slide along the first mounting rail or the second mounting rail, so that the suction cup assembly aligns with the product and absorbs the product, without the need to replace or disassemble the transfer fixture. The patent with publication number CN110369873A discloses a fully automatic flipping and blanking sheet metal laser welding system. After the sheet metal is welded, the sheet metal passes through a blanking conveyor belt, and the sheet metal is sucked up by the suction cup of the flipping machine, and then the back of the sheet metal is sucked by the magnetic suction device of the blanking robot to complete the flipping.

[0003] However, in the field of automotive sheet metal welding, it is often necessary to use a blanking electromagnet to achieve suction to transfer the sheet metal after the welding process has been completed. In many cases, due to factors such as installation space limitations, the blanking electromagnet cannot be installed on a robot arm. It can only form a suction module and be installed on a transmission mechanism with a conveyor belt structure. For example, Patent No. CN209532559U discloses a magnetic transmission mechanism for special steel plate tailor welding. How to transfer the welded sheet metal to the above-mentioned magnetic transmission mechanism is a problem that needs to be considered. The existing technology mainly achieves sheet metal transfer by manual pushing, which is time-consuming and labor-intensive. In addition, the shapes and specifications of automotive sheet metal vary greatly, and many are irregularly shaped. The suction cup assembly structure in the existing technology is mostly a traditional rectangular or square matrix layout. Even if the position of each suction cup assembly can be adjusted as in Patent CN218988081U, the adjusted suction cup layout is still approximately rectangular or square, which is difficult to meet the suction requirements of irregularly shaped sheet metal. Summary of the Invention

[0004] The purpose of the present invention is to provide a laser welding blanking mechanism for automobile plates, which can accurately control the lifting height of the suction cup assembly to ensure that the welded plates are smoothly transferred to the magnetic transmission mechanism.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 7 As shown, the present invention includes a moving frame 5, a lifting seat 2, an upper cylinder 7, a lower cylinder 6, an adapter plate 4, a connecting rod 3 and a suction cup assembly 1, wherein Figures 1 to 3 As shown, two lifting seats 2 are respectively arranged on both sides of the mobile frame 5, and the lower ends of the two lifting seats 2 are fixedly connected to a slot beam 202, and each group of suction cup components 1 can be adjustably arranged on the slot beam 202, as shown in FIG. Figures 1-2As shown, the movable frame 5 is provided with a transmission shaft 504, and an adapter plate 4 is provided at both ends of the transmission shaft 504, the lower end of the adapter plate 4 is hinged to the upper end of the connecting rod 3 on the corresponding side, and the lower end of the connecting rod 3 is hinged to the upper end of the lifting seat 2 on the corresponding side, and the upper and lower parts of the movable frame 5 are provided with cylinder fine-tuning devices 8, and the cylinder body of the upper cylinder 7 and the cylinder body of the lower cylinder 6 are respectively hinged to the corresponding cylinder fine-tuning devices 8, and the output shaft of the upper cylinder 7 and the output shaft of the lower cylinder 6 are both hinged to the adapter plate 4 on the corresponding side. When the present invention is working, the upper cylinder 7 and the lower cylinder 6 cooperate to extend and retract to drive the adapter plate 4 to rotate. The rotation of the adapter plate 4 drives the lifting seat 2 to move up and down through the connecting rod 3, thereby driving the slot beam 202 to drive each group of suction cup assemblies 1 to move up and down. When the plate workpiece 10 is welded, the mobile frame 5 moves to the top of the plate workpiece 10, and then the suction cup assembly 1 descends to achieve adsorption of the plate workpiece 10. Then, the mobile frame 5 drives the plate workpiece 10 to move to the input end of the next station (magnetic transmission mechanism). The driving mechanism of the mobile frame 5 is a well-known technology in the art, for example, the X-axis moving mechanism in the CN110877826B patent or other suitable structures can be adopted.

[0030] like Figures 3-4 As shown, in this embodiment, the suction cup assembly 1 includes a suction cup frame 102, a clamping block 101, a suction cup adjustment block 105, a clamping block adjustment block 108 and a suction cup 106, wherein the clamping block adjustment block 108 and the suction cup adjustment block 105 are both adjustably arranged in the suction cup frame 102, the clamping block 101 is installed on the corresponding clamping block adjustment block 108, and the suction cup 106 is installed on the corresponding suction cup adjustment block 105. Figure 3 As shown, the clamping block 101 is provided with a clamping protrusion 1011 that cooperates with the corresponding side clamping slot of the clamping slot beam 202. When the present invention is used, after the operator moves the clamping block adjustment blocks 108 on both sides outward, the clamping blocks 101 on both sides no longer clamp the clamping slot beam 202. At this time, the entire suction cup frame 102 can be adjusted along the length direction of the clamping slot beam 202. When the position of the suction cup assembly 1 is determined, the clamping block adjustment block 108 is moved again to re-clamp the clamping block 101 on the clamping slot beam 202. In addition, the present invention can also adjust the position of each suction cup 106 on the suction cup frame 102 according to actual needs, such as Figure 7 As shown, since the plate workpiece 10 targeted by the present invention is often a special-shaped workpiece, the present invention can adjust the position of the suction cup frame 102 and the position of the suction cup 106 so that the layout of the suction cup 106 on the suction cup assembly 1 can better match the shape of the plate workpiece 10, and the use is flexible and the scope of application is greatly improved.

[0031] like Figure 3As shown, in this embodiment, the suction cup frame 102 is provided with an adjustment slot 1021, and the two sides of the clamping block adjustment block 108 are fixed to the suction cup frame 102 by clamping block fastening bolts 104, and the clamping block fastening bolts 104 pass through the corresponding adjustment slots 1021. After the operator loosens the clamping block fastening bolts 104 outward, the clamping block adjustment block 108 can be moved and adjusted within the suction cup frame 102, and its adjustment range is the length range of the adjustment slot 1021. Figure 3 As shown, when the two clamping blocks 108 move outward, the two clamping blocks 101 release the clamping slot beam 202, and when the two clamping blocks 108 move inward, the two clamping blocks 101 clamp the clamping slot beam 202. Figures 3-4 As shown, in this embodiment, the clamping block 101 is fixed to the corresponding clamping block adjustment block 108 by a clamping block mounting bolt 103 , and the clamping block mounting bolt 103 is axially perpendicular to the clamping block fastening bolt 104 .

[0032] like Figures 3-4 As shown, in this embodiment, the suction cup frame 102 is provided with multiple groups of adjustment screw holes 1022. The suction cup adjustment block 105 is fixed to the suction cup frame 102 via suction cup fastening bolts 107, and the suction cup fastening bolts 107 pass through a corresponding group of adjustment screw holes 1022. The design of each group of adjustment screw holes 1022 enables position adjustment of the suction cup adjustment block 105, and the specific position and number of each group of adjustment screw holes 1022 are designed according to actual needs. In addition, since the suction cup frame 102 is generally long and the present invention only utilizes a single beam, the slot beam 202, for support, in order to ensure the support strength of the suction cup frame 102, this embodiment adopts a structure of multiple groups of adjustment screw holes 1022 to achieve position adjustment of the suction cup adjustment block 105.

[0033] like Figure 1 As shown, in this embodiment, a connecting plate 201 is provided on the lower side of the lifting seat 2, and the connecting plate 201 is fixedly connected to the slot beam 202 by bolts. In addition, a slide rail 501 is provided on the mobile frame 5, and a slider 203 is provided on the lifting seat 2 to cooperate with the slide rail 501 to achieve a sliding connection between it and the mobile frame 5, and at the same time, it can also ensure that the lifting seat 2 can be lifted vertically.

[0034] like Figure 1 As shown, in this embodiment, an adapter seat 502 is provided on the movable frame 5, and both ends of the transmission shaft 504 are respectively supported and installed on the adapter seat 502 on the corresponding side through bearings, and the middle part of the adapter plate 4 is fixedly connected to the corresponding end of the transmission shaft 504. The adapter plates 4 on both sides of the movable frame 5 are driven to rotate synchronously by the transmission shaft 504, thereby ensuring that the slot beam 202 remains horizontal during the lifting and lowering action.

[0035] like Figure 1As shown, in this embodiment, the movable frame 5 is provided with a fixed plate 503, and the cylinder fine-tuning device 8 is fixedly mounted on the corresponding fixed plate 503, as shown in FIG. Figure 5 As shown, the lower end of the cylinder fine-tuning device 8 is provided with an articulated rod 805 that can be adjusted up and down, and the upper end of the cylinder body of the upper cylinder 7 and the lower end of the cylinder body of the lower cylinder 6 are respectively hinged to the corresponding articulated rod 805. The present invention adjusts the positions of the upper cylinder 7 and the lower cylinder 6 by adjusting the height of the articulated rod 805, thereby achieving the purpose of adjusting the driving range of the two cylinders according to different plate thicknesses. When the plate is relatively thick, the cylinder body position of the upper cylinder 7 is adjusted upward, and the cylinder body position of the lower cylinder 6 is adjusted downward. In this way, the output shafts of the two cylinders have a larger adjustment range to ensure that the thicker plate can smoothly leave the welding station and transfer to the next station. When the plate is relatively thin, the cylinder body position of the upper cylinder 7 is adjusted downward, and the cylinder body position of the lower cylinder 6 is adjusted upward.

[0036] In addition, Figure 1As shown, a first sensor bracket is provided at the lower end of the cylinder body of the upper cylinder 7, and two position sensors 9 are provided on the first sensor bracket, and a first sensing plate 901 cooperating with the position sensor 9 is provided on the output shaft of the upper cylinder 7, and a second sensor bracket is provided at the upper end of the cylinder body of the lower cylinder 6, and a position sensor 9 is provided on the second sensor bracket, and a second sensing plate 902 cooperating with the position sensor 9 is provided on the output shaft of the lower cylinder 6. The present invention detects the end position of the adapter plate 4 by cooperating with the position sensor 9, and can also detect the displacement of the upper and lower cylinder output shafts by cooperating with the position sensor 9 through the first sensing plate 901 and the second sensing plate 902. Then, the equipment control system can calculate the lifting height of the lifting seat 2, that is, the lifting height of each group of suction cup assemblies 1, through geometric conversion according to the detection conditions of several position sensors 9, thereby realizing precise control of the lifting height of the plate workpiece 10. The plate workpiece 10 targeted by the present invention needs to be transferred to a magnetic transfer mechanism provided with a magnetic suction module, and the magnetic suction force range of the magnetic suction module is limited. Therefore, the transfer height of the plate workpiece 10 is generally the lower the better. In this way, when the suction cup assembly 1 releases the plate workpiece 10, the plate workpiece 10 is directly adsorbed on the magnetic suction module to be fixed, and at the same time, it can also ensure that the transfer positioning will not deviate. If the transfer height of the plate workpiece 10 is too high, when the suction cup assembly 1 is released, the plate workpiece 10 will first be dropped to the magnetic suction force range by gravity, and then adsorbed by the magnetic suction module. The position of the plate workpiece 10 may change during the gravity drop, which is not conducive to subsequent processing and positioning. In addition, welding stations often use welding electromagnets to achieve plate adsorption and positioning. Therefore, the rising height of the suction cup assembly 1 also needs to be considered to ensure that the plate is separated from the welding electromagnet. The present invention achieves precise control of the lifting height of the suction cup assembly 1 through the combination of the upper cylinder 7, lower cylinder 6, position sensor 9, and cylinder fine-tuning device 8, thereby ensuring smooth sheet transfer. The upper cylinder 7 and lower cylinder 6 cooperate to ensure that the lifting range of the suction cup assembly 1 is not excessive. Furthermore, the lifting range can be adjusted according to the thickness of the sheet material through the cylinder fine-tuning device 8 and other structures, thereby increasing the flexibility and applicability of the present invention. The position sensor 9 is well known in the art, and for example, a KEYENCE brand sensor can be used.

[0037] like Figures 5-6As shown, in this embodiment, the cylinder fine-tuning device 8 includes a mounting seat 802, a knob 801, an adjusting slider 806 and a hinged rod 805. A slider cavity 8022 is provided inside the mounting seat 802, and the adjusting slider 806 is provided in the slider cavity 8022. The knob shaft 8011 on the lower side of the knob 801 is threadedly inserted into the upper end of the mounting seat 802, and the lower end of the knob shaft 8011 is fixedly connected to the upper end of the adjusting slider 806. The hinged rod 805 is liftably inserted into the lower end of the mounting seat 802, and the upper end of the hinged rod 805 is fixedly connected to the lower end of the adjusting slider 806. The operator can drive the adjusting slider 806 to move up and down along the slider cavity 8022 by turning the knob 801, thereby driving the hinged rod 805 to move up and down. In addition, Figure 5 As shown, the mounting seat 802 is provided with an indicator plate 804, an indicator needle 803 and a slide groove 8021, wherein the indicator needle 803 is connected to the adjustment slider 806 via a connecting shaft, and the connecting shaft passes through the slide groove 8021, and the indicator plate 804 is provided with a scale to cooperate with the indicator needle 803 to indicate the lifting and lowering adjustment height of the articulated rod 805, thereby assisting in controlling the height position adjustment of the upper and lower cylinders.

[0038] The working principle of the present invention is:

[0039] When the present invention is working, the upper cylinder 7 and the lower cylinder 6 cooperate to extend and retract to drive the adapter plate 4 to rotate. The rotation of the adapter plate 4 drives the lifting seat 2 to move up and down through the connecting rod 3, and then drives the slot beam 202 to drive each group of suction cup assemblies 1 to move up and down. After the welding of the plate workpiece 10 is completed, the movable frame 5 moves to the top of the plate workpiece 10, and then the suction cup assembly 1 descends to achieve the adsorption of the plate workpiece 10, and then the movable frame 5 drives the plate workpiece 10 to move to the input end of the next workstation (magnetic transmission mechanism).

[0040] The position of the suction cup frame 102 of each group of suction cup assemblies 1 of the present invention can be adjusted along the length direction of the slot beam 202 according to actual needs, and the position of each suction cup adjustment block 105 on the suction cup frame 102 can also be adjusted along the length of the suction cup frame 102 according to actual needs, such as Figure 7 As shown, because the plate workpieces 10 targeted by the present invention have different shapes, the present invention can make the suction cup layout no longer limited to the rectangular or square matrix form through the above adjustment, which can meet the adsorption requirements of various special-shaped workpieces.

[0041] In addition, the present invention needs to use the suction cup assembly 1 to pick up the plate that has completed the welding process from the welding positioning electromagnet of the welding station, and then transfer it to the magnetic transmission mechanism provided with a magnetic suction module. Therefore, the present invention must ensure that the plate can be separated from the welding electromagnet, and must ensure that the height of the plate will not be too high to avoid positioning deviation after being transferred to the magnetic transmission mechanism. Therefore, the present invention achieves the purpose of accurately controlling the rising height of the suction cup assembly 1 through the combination of structures such as the upper cylinder 7, the lower cylinder 6, the position sensor 9, and the cylinder fine-tuning device 8. The upper cylinder 7 and the lower cylinder 6 cooperate to drive to ensure that the lifting range of the suction cup assembly 1 will not be too large. At the same time, it can also be convenient to adjust the lifting range according to different plate thicknesses through structures such as the cylinder fine-tuning device 8. This not only ensures the smooth transfer of the plate, but also improves the flexibility and scope of application of the present invention.
