Technical Field
[0001] This utility model relates to the field of double steel strip welding technology, and in particular to a double steel strip welding device with punching function. Background Technology
[0002] Injection molded parts often have steel inserts, and some steel inserts are formed by welding two steel sheets together.
[0003] Currently, the double steel sheet welding method mainly involves feeding the first and second steel sheets as individual, pre-cut steel sheets. A robotic arm then picks up the first and second steel sheets respectively, performs pitch and positioning adjustments on them sequentially, and finally places them into welding fixtures using the robotic arm. The first and second steel sheets are then welded together to form the finished steel sheet. While this method can achieve double steel sheet welding, it requires a large number of workstations and equipment. The number of debugging attempts at each workstation also increases, leading to debugging difficulties. Furthermore, the equipment failure rate increases, resulting in low uptime and a large footprint. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides a double steel strip welding device with punching capability. It employs a double steel strip feeding method and combines the punching and welding of the double steel strips in the same workstation, thereby effectively reducing the number of workstations, thus reducing the number of equipment debugging sessions and the difficulty of debugging, as well as reducing the equipment failure rate, and ultimately improving the uptime.
[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0006] This utility model provides a double steel strip welding device with punching capability for processing a first steel strip and a second steel strip that can move at a fixed point. It includes a laser welding mechanism and a positioning punching mechanism for positioning and punching the double steel strips. The positioning punching mechanism includes a punching die for punching the steel sheet of the second steel strip, a positioning plate for coarse positioning of the double steel strip, and a positioning pin for fine positioning of the double steel strip. The punching die and the positioning plate are arranged vertically. The positioning plate has a first guide groove and a second guide groove arranged in a cross configuration on the side facing the punching die. The first guide groove corresponds to the first steel strip, and the second guide groove corresponds to the second steel strip. The positioning pin is vertically mounted on the positioning plate away from the punching die. On one side, the positioning pin is detachably inserted into the positioning holes of the first steel strip and the second steel strip, so that the steel sheet welding point of the first steel strip is aligned with the corresponding steel sheet welding point of the second steel strip; the punching die is provided with a laser through hole to allow the laser emitted by the laser welding mechanism, and when the first steel strip and the second steel strip are simultaneously limited by the positioning pin, the punching die presses down and clamps the steel sheets of the first steel strip and the second steel strip, and punches the steel sheet of the second steel strip simultaneously. Then, the laser emitted by the laser welding mechanism welds the steel sheet welding point between the first steel strip and the second steel strip through the laser through hole, so that the steel sheet of the second steel strip that has been punched is fixed to the corresponding steel sheet of the first steel strip.
[0007] Furthermore, the second guide groove is provided with a plurality of guide bosses spaced apart. The guide bosses are provided with slits through which the material strip of the second steel strip passes. The material strip of the second steel strip is movably inserted through the slits so that the first steel strip and the second steel strip are spaced apart before punching.
[0008] Furthermore, the extension direction of the first guide groove is perpendicular to the extension direction of the second guide groove.
[0009] Furthermore, the positioning punching mechanism also includes a mounting bracket and an ejector assembly mounted on the mounting bracket. The positioning plate is fixed to the mounting bracket, and the ejector assembly is disposed between the positioning plate and the mounting bracket. The positioning plate is provided with a clearance through hole that cooperates with the extension of the positioning pin. The positioning pin is movably inserted through the clearance through hole, and the ejector assembly drives the positioning pin to extend or retract the positioning pin through the clearance through hole.
[0010] Furthermore, the ejection assembly includes an ejection plate and a first driver. The end of the positioning pin facing away from the positioning plate is mounted on the ejection plate. The first driver is mounted on the mounting bracket and drives the ejection plate to rise and fall, thereby driving the positioning pin to rise and fall.
[0011] Furthermore, the first actuator is a first cylinder.
[0012] Furthermore, the punching die includes a mounting plate, a die mounted on the mounting plate, and a second driver for driving the mounting plate to rise and fall; the mounting plate is provided with the laser through hole, and the die is located between the mounting plate and the positioning plate; the second driver is fixed to the mounting bracket, and the mounting plate is mounted on the mounting bracket in a height-adjustable manner through guide columns; the second driver is used to drive the mounting plate to rise and fall, thereby driving the die to rise and fall; the die presses down and fits the positioning hole of the second steel strip into the positioning pin, so as to ensure that the steel sheet welding point of the first steel strip is aligned with the corresponding steel sheet welding point of the second steel strip, and the steel sheet of the second steel strip is pressed and punched simultaneously.
[0013] Furthermore, the second actuator is a second cylinder.
[0014] Furthermore, it also includes a lifting slide, on which the laser welding mechanism is mounted. The lifting slide drives the laser welding mechanism to rise and fall, so that the laser welding mechanism moves closer to or further away from the positioning and punching mechanism.
[0015] The technical solution provided by this utility model has the following beneficial effects:
[0016] This utility model adopts a double steel strip feeding method and combines the punching and welding of the double steel strips in the same workstation to effectively reduce the number of workstations, that is, to effectively reduce the number of equipment and processes, thereby reducing the equipment footprint and reducing the number of debugging stations.

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0027] Reference Figures 1 to 8 As shown, this embodiment provides a double steel strip welding device with punching capability (hereinafter referred to as the welding device) for welding such... Figure 6 The first steel strip 1 shown and as Figure 7 The steel sheets of the second steel strip 2 shown are welded together to form the finished steel sheet 6. The first steel strip 1 and the second steel strip 2 are respectively set to be movable at fixed points, that is, according to the preset production rhythm and the steel strip pulling distance is set to a fixed quantity each time.
[0028] like Figure 1 As shown, the welding device in this embodiment includes a lifting slide 5, a laser welding mechanism 3, and a positioning and punching mechanism 4 for positioning and punching double steel strips.
[0029] The laser welding mechanism 3 is mounted on the lifting slide 5. The lifting slide 5 drives the laser welding mechanism 3 to rise and fall, so that the laser welding mechanism 3 approaches or moves away from the positioning punching mechanism 4. When the laser welding mechanism 3 descends and approaches the positioning punching mechanism 4, it laser welds the two steel sheets located in the positioning punching mechanism 4 together. When the laser welding mechanism 3 rises and moves away from the positioning punching mechanism 4, the laser welding is completed. At the same time, it ensures that there is no mechanical interference between the laser welding mechanism 3 and the positioning punching mechanism 4.
[0030] like Figure 2 and Figure 3As shown, the positioning punching mechanism 4 includes a punching die 41 for punching the steel sheet of the second steel strip 2, a positioning plate 42 for coarse positioning of the double steel strip, and a positioning pin 43 for fine positioning of the double steel strip. The punching die 41 and the positioning plate 42 are arranged in an upper and lower position, and the punching die 41 is provided with a laser through hole 414 to allow the laser emitted by the laser welding mechanism 3 to pass through.
[0031] like Figure 2 , Figure 4 and Figure 5 As shown, the positioning plate 42 has a first guide groove 421 and a second guide groove 422 arranged in a cross configuration on the upper side facing the punching die 41. The first guide groove 421 corresponds to the first steel strip 1, and the second guide groove 422 corresponds to the second steel strip 2. The extending direction of the first guide groove 421 is perpendicular to the extending direction of the second guide groove 422 to ensure that the moving trajectories of the first steel strip 1 and the second steel strip 2 are perpendicular to each other. Of course, in other embodiments, the extending direction of the first guide groove 421 may not be perpendicular to the extending direction of the second guide groove 422.
[0032] The positioning pin 43 is mounted on the lower side of the positioning plate 42 away from the punching die 41 and can be raised and lowered. The positioning pin 43 can be detachably inserted into the positioning holes of the first steel strip 1 and the second steel strip 2 so that the steel sheet welding point of the first steel strip 1 is aligned with the corresponding steel sheet welding point of the second steel strip 2.
[0033] When the first steel strip 1 and the second steel strip 2 are simultaneously limited by the positioning pin 43, the punching die 41 presses down and clamps the steel sheets of the first steel strip 1 and the second steel strip 2, simultaneously punching the steel sheet of the second steel strip 2. Then, the laser emitted by the laser welding mechanism 3 welds the welding points of the steel sheets between the first steel strip 1 and the second steel strip 2 through the laser through hole 414, so that the broken steel sheet of the second steel strip 2 is laser-welded and fixed to the corresponding steel sheet of the first steel strip 1, thus forming a shape like... Figure 8 The finished steel sheet 6 shown is continued to be connected to the material strip of the first steel strip 1, and then collected in coil or strip form.
[0034] In this embodiment, as Figure 2 and Figure 3As shown, the positioning punching mechanism 4 also includes a mounting bracket 45 and an ejector assembly 44 mounted on the mounting bracket 45. The positioning plate 42 is fixed to the mounting bracket 45, and the ejector assembly 44 is disposed between the positioning plate 42 and the mounting bracket 45. The positioning plate 42 is provided with a clearance through hole for the positioning pin 43 to extend out. The positioning pin 43 is movably inserted into the clearance through hole, and the ejector assembly 44 drives the positioning pin 43 to extend or retract into the clearance through hole. Specifically, the ejector assembly 44 includes a top... The ejector plate 441 and the first driver 442 are configured as follows: the first driver 442 is a first cylinder; the lower end of the positioning pin 43, away from the positioning plate 42, is mounted on the ejector plate 441; the first driver 442 is mounted on the mounting bracket 45; the ejector plate 441 is mounted on the mounting bracket 45 in a height-adjustable manner via a first set of guide posts; and the telescopic end of the first driver 442 is mounted on the ejector plate 441 to drive the ejector plate 441 to rise and fall along the guiding direction of the guide posts, thereby driving the positioning pin 43 to rise, fall, extend, or retract. Of course, in other embodiments, the first driver 442 may also be a motor assembly with a transmission unit.
[0035] The punching die 41 includes a mounting plate 411, a die 412 mounted on the mounting plate 411, and a second driver 413 for driving the mounting plate 411 to rise and fall. Specifically, the second driver 413 is a second cylinder. The mounting plate 411 is provided with a laser through hole 414. The die 412 is located between the mounting plate 411 and the positioning plate 42. The second driver 413 is fixed to the mounting bracket 45. The mounting plate 411 is mounted on the mounting bracket 45 in a height-adjustable manner through a second set of guide columns. The second driver 413 is used to drive the mounting plate 411 to rise and fall, thereby driving the die 412 to rise and fall. The die 412 presses down and fits the positioning hole of the second steel strip 2 into the positioning pin 43 to ensure that the steel sheet welding point of the first steel strip 1 is aligned with the corresponding steel sheet welding point of the second steel strip 2, and the steel sheet of the second steel strip 2 is pressed and punched simultaneously.
[0036] In specific implementation, such as Figure 5 As shown, the second guide groove 422 is provided with a plurality of guide bosses 423 spaced apart. The guide bosses 423 are provided with a gap through which the material strip of the second steel strip 2 passes. The material strip of the second steel strip 2 is movably inserted into the gap so that the first steel strip 1 and the second steel strip 2 are spaced apart before punching, so as to ensure that the first steel strip 1 and the second steel strip 2 will not interfere with each other when pulling the material.
[0037] This embodiment uses two first steel strips 1 and two second steel strips 2, and correspondingly, two each of the first guide groove 421, the second guide groove 422, and the die 412 are set to form a dual-station processing operation. Of course, one or more first steel strips 1 and / or one or more second steel strips 2 can also be used to form a single-station or multi-station processing operation.
[0038] In addition, the welding apparatus of this embodiment uses the following double steel strip welding method to process the steel sheets of the double steel strips, specifically including the following steps:
[0039] Step S1: The first steel strip 1 and the second steel strip 2 are respectively moved through the first guide groove 421 and the second guide groove 422 of the positioning plate 42 of the positioning punching mechanism 4 to coarsely position the first steel strip 1 and the second steel strip 2. The first guide groove 421 and the second guide groove 422 are arranged in a cross pattern, and the second steel strip 2 and the first steel strip 1 are arranged with an upper and lower spacing.
[0040] Step S2: Raise the positioning pin 43 of the positioning punching mechanism 4 so that the positioning pin 43 extends out of the positioning plate 42 and is inserted into the positioning hole of the first steel strip 1 to finely position the steel sheet of the first steel strip 1.
[0041] In step S3, the punching die 41 of the positioning punching mechanism 4 is pressed down so that the positioning hole of the second steel strip 2 is fitted onto the positioning pin 43, thereby ensuring that the steel sheet welding point of the first steel strip 1 is aligned with the steel sheet welding point of the second steel strip 2. When the steel sheets of the first steel strip 1 and the second steel strip 2 are pressed together, the punching die 41 cuts the steel sheet of the second steel strip 2.
[0042] In step S4, the laser welding mechanism 3 is lowered so that the laser emitted by the laser welding mechanism 3 passes through the laser through hole 414 of the punching die 41 and is aligned with the steel sheet welding point of the first steel strip 1 and the second steel strip 2, so as to weld the cut steel sheet of the second steel strip 2 to the corresponding steel sheet of the first steel strip 1.
[0043] In step S5, the positioning pin 43 is lowered and the positioning plate 42 is retracted. Then, the first steel strip 1 and the second steel strip 2 are pulled at fixed points to move the next steel sheet to be processed to the processing station.
[0044] In this embodiment, the positioning punching mechanism 4 integrates the punching process and the laser welding process to form a single workstation. Therefore, compared with the number of workstations in the prior art, the number of workstations in this embodiment is significantly reduced, and the equipment debugging is also relatively convenient and quick.
[0045] This embodiment adopts a double steel strip feeding method and combines the punching and welding of the double steel strips in the same workstation to effectively reduce the number of workstations, that is, to effectively reduce the number of equipment and processes, thereby reducing the equipment footprint and reducing the number of debugging stations. At the same time, the equipment debugging is convenient and quick, thereby effectively reducing the number of equipment debugging times and debugging difficulty, as well as reducing the equipment failure rate, and thus improving the utilization rate. This can significantly improve production efficiency and increase production capacity.
[0046] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
