Description

Technical Field

[0001] This invention relates to the field of plate welding equipment technology, and specifically to a welding equipment for irregularly shaped metal plates. Background Technology

[0002] In the large-scale stamping industry, maximizing the capacity of production equipment and improving material utilization are key to the industry's survival. Because large-scale stamping equipment is expensive, adding more equipment is a huge expense. Therefore, large stamping presses typically need to stamp as many products as possible simultaneously in a single stroke to maximize equipment capacity and survive in the fierce market competition.

[0003] Given the characteristics of these industries, it is typically necessary to weld sheet metal from different products together in a specific order to prevent misalignment from affecting precision during stamping. However, current technology usually uses connectors to weld multiple sheet metals of different specifications and shapes together using resistance welding. This method requires stacking the sheet metal on the connector at approximately 10mm intervals, with each sheet metal overlapping the others by 10mm, resulting in inefficient material utilization and waste. Furthermore, the sheet metal can shift during welding, affecting the welding effect and making it impossible to simultaneously weld sheet metals of different specifications.

[0004] Therefore, there is still room for improvement and development in existing technologies. Summary of the Invention

[0005] The purpose of this invention is to provide a welding device for irregularly shaped metal sheets, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution applied in this invention is as follows:

[0007] A welding device for irregularly shaped metal sheets includes a body, within which a sheet processing platform and a sheet welding robot are provided. The sheet processing platform is fixed within the body and is used to support multiple sheets. The sheet processing platform is equipped with sheet positioning devices for positioning the holes, grooves, bottom, and outer edges of the sheets. The sheet welding robot is movably disposed within the body and located on the first side of the sheet processing platform, and is used to weld multiple sheets located on the sheet processing platform.

[0008] According to the above scheme, multiple sheet support members are arranged side by side and spaced apart on the sheet processing platform. The sheet positioning device includes a first sheet positioning device, a second sheet positioning device, and a third sheet positioning device. The first sheet positioning device is movably disposed below the sheet support members and is used to position the holes and grooves of the sheet. The second sheet positioning device is fixed on the sheet support members and is used to position the bottom of the sheet. The third sheet positioning device is slidably disposed on the sheet support members and is used to position the outer periphery of the sheet.

[0009] According to the above scheme, the first positioning device for the sheet metal includes an X-axis module, a Y-axis module, a Z-axis module, and a lifting positioning pin. The lifting positioning pin is installed on the Z-axis module, which is used to drive the lifting positioning pin to move up and down relative to the sheet metal support. The Z-axis module is installed on the Y-axis module, which is used to drive the Z-axis module to move back and forth relative to the sheet metal support. The Y-axis module is installed on the X-axis module, which is used to drive the Y-axis module to move left and right relative to the sheet metal support.

[0010] According to the above scheme, a clearance groove is provided between two adjacent plate support members to facilitate the passage of the lifting positioning pin.

[0011] According to the above scheme, the second positioning device for the plate includes multiple electromagnets that are spaced apart and installed on the plate support.

[0012] According to the above scheme, the third positioning device for the plate includes multiple positioning columns that are slidably disposed on the plate support.

[0013] According to the above scheme, the plate support is provided with a guide groove, and multiple positioning posts are slidably disposed in the guide groove. An adjustable bolt assembly is provided between the positioning posts and the plate support.

[0014] According to the above scheme, the plate processing platform is also provided with a plate auxiliary connection device; the plate auxiliary connection device includes a first plate auxiliary component and a second plate auxiliary component, a first plate welding anti-adhesion component is provided below the first plate auxiliary component, and a second plate welding anti-adhesion component is provided below the second plate auxiliary component, wherein the welding anti-adhesion component is a copper sheet.

[0015] According to the above scheme, the second side of the plate processing platform is provided with a plate loading port, and a safety light curtain device is provided inside the plate loading port.

[0016] According to the above scheme, the machine body is equipped with a control device for controlling the operation of the plate welding robot, the first plate positioning device and the second plate positioning device.

[0017] Beneficial effects of this invention:

[0018] This invention features a plate positioning device on the plate processing platform for positioning the holes, slots, bottom, and outer edges of the plate. By positioning the plate at different locations, especially through multiple X, Y, and Z axis modules, precise positioning of any plate is achieved, significantly reducing the time required to reset positioning and limiting mechanisms when switching products. This prevents plate displacement during welding and also prevents heat deformation, resulting in more reliable and stable welding. A plate welding robot welds the joints of adjacent plates, solving the material waste problem associated with traditional resistance welding and significantly reducing manufacturing costs. It also addresses the issue of connectors occupying part of the plate during welding, leading to material underutilization and waste. A liftable plate auxiliary connecting device provides a welding bridge between plates with large weld seams, enabling the welding of various irregularly shaped metal plates and solving the problem of different plates not being able to be welded on the same platform. A copper sheet is placed below the plate auxiliary connecting device. The copper sheet quickly dissipates heat and, due to its high melting point, does not adhere to the plate being welded, further preventing heat deformation. Attached Figure Description

[0029] The technical solution of the present invention will be described below with reference to the accompanying drawings and embodiments.

[0030] In existing technologies, connectors are typically used to weld two plates of different sizes and shapes together. However, the connectors occupy part of the plate space, resulting in the material not being fully utilized and thus being wasted. Furthermore, the plate displacement during welding can affect the welding effect.

[0031] Therefore, such as Figures 1 to 8 As shown, the present invention provides a welding device for irregularly shaped metal sheets, which includes a body 1, which serves as the external frame of the device and is internally designed to accommodate and support all functional components. Specifically, a sheet metal processing platform 2 and a sheet metal welding robot 3 are installed inside the machine body 1. The sheet metal processing platform 2 is fixed inside the machine body 1 and is used to support multiple sheets 10. That is, the sheet metal processing platform 2 serves as a support structure for multiple sheets 10. It is a planar structure, and multiple sheets 10 to be welded are loaded onto the sheet metal processing platform 2. It should be noted that the sheet metal processing platform 2 is equipped with sheet metal positioning devices for positioning the holes, slots, bottom, and outer edges of the sheet metal 10. By positioning the sheet metal 10 at different positions, displacement of the sheet metal 10 during welding can be prevented, thereby making the welding effect more reliable and stable. The sheet metal welding robot 3 is movably installed inside the machine body 1 and located on the first side of the sheet metal processing platform 2. The sheet metal welding robot 3 is used to weld multiple sheets 10 located on the sheet metal processing platform 2. It should be noted that the movement trajectory of the sheet metal welding robot 3 can cover the entire surface area of ​​the sheet metal processing platform 2. That is, when multiple sheets are placed at any position on the sheet metal processing platform 2, welding can be performed at the joint of adjacent sheets 10.

[0032] To achieve separate positioning of the slots, bottom, and outer edge of the plate 10, such as... Figure 2As shown, the present invention provides a plurality of plate support members 5 arranged side by side and spaced apart on the plate processing platform 2. The plate positioning device includes a first plate positioning device 6, a second plate positioning device 7, and a third plate positioning device 8. The first plate positioning device 6 is movably disposed below the plate support member 5 and is used to position the holes and grooves of the plate 10, i.e., it can be positioned according to different hole positions on the plate 10. The second plate positioning device 7 is fixed to the plate support member 5 and is used to position the bottom of the plate 10. The third plate positioning device 8 is slidably disposed on the plate support member 5 and is used to position the outer periphery of the plate 10. Specifically, by cooperating, the first plate positioning device 6, the second plate positioning device 7, and the third plate positioning device 8 can position multiple plates 10 at different positions, with a very reliable positioning effect, completely preventing displacement of the plate 10 during the welding process.

[0033] like Figure 2 and 3 As shown, the first positioning device 6 for the sheet metal includes an X-axis module 11, a Y-axis module 12, a Z-axis module 13, and a lifting positioning pin 14. The lifting positioning pin 14 is mounted on the Z-axis module 13, which drives the lifting positioning pin 14 to move vertically relative to the sheet metal support 5. The Z-axis module 13 is mounted on the Y-axis module 12, which drives the Z-axis module 13 to move forward and backward relative to the sheet metal support 5. The Y-axis module 12 is mounted on the X-axis module 11, which drives the Y-axis module 12 to move left and right relative to the sheet metal support 5. An obstacle clearance groove is provided between two adjacent sheet metal supports 5 to facilitate the passage of the lifting positioning pin 14. Specifically, the X-axis module 11, Y-axis module 12 and Z-axis module 13 work together to adjust the displacement of the lifting positioning pin 14 in the X-axis, Y-axis and Z-axis directions, so that the position of the lifting positioning pin 14 can be adjusted arbitrarily according to different plates 10 to adapt to the holes and slots at different positions on the plate 10.

[0034] The position of the lifting positioning pin 14 can be preset according to the position of the hole and groove on the plate 10. When the plate 10 is loaded onto the plate processing platform 2, the hole and groove can be matched with the lifting positioning pin 14 to achieve positioning of the plate 10.

[0035] like Figure 4 and Figure 5 As shown, the second positioning device 7 for the plate material includes multiple electromagnets 15 spaced apart on the plate material support 5. By energizing the multiple electromagnets 15 to generate magnetic force, the bottom of the plate material 10 on the plate material support 5 can be attracted and positioned.

[0036] like Figure 4 and Figure 6As shown, the third positioning device 8 for the sheet metal includes a plurality of positioning posts 16 slidably disposed on the sheet metal support 5. The outer edge of the sheet metal 10 on the sheet metal support 5 can be positioned by the plurality of positioning posts 16.

[0037] Furthermore, the plate support 5 is provided with a guide groove, and multiple positioning posts 16 are slidably disposed in the guide groove. An adjustable bolt assembly is provided between the positioning posts 16 and the plate support 5. The positioning posts 16 are provided with elongated slots. The bolt assembly passes through the elongated slots and is threaded onto the plate support 5. When it is necessary to adjust the position of the positioning post 16, first loosen the bolt assembly, then adjust the position of the positioning post 16 so that the positioning post 16 abuts against the outer edge of the plate 10. After the adjustment is completed, finally tighten the bolt assembly to lock the position of the positioning post 16, thereby achieving the purpose of positioning the outer edge of the plate 10.

[0038] When the distance between two or more plates is large, it will prevent the two plates from being directly welded. Therefore, if... Figure 4 and Figure 7 As shown, the sheet metal processing platform 2 is also equipped with a sheet metal auxiliary connection device 9; the sheet metal auxiliary connection device 9 includes a first sheet metal auxiliary component 17 and a second sheet metal auxiliary component 18. A first sheet metal welding anti-adhesion component 19 is provided below the first sheet metal auxiliary component 17, and a second sheet metal welding anti-adhesion component 20 is provided below the second sheet metal auxiliary component 18. The welding anti-adhesion components 19 and 20 are copper sheets. That is, the sheet metal auxiliary connection device 9 can be used to splice two or more sheets that are far apart. First, the first sheet metal auxiliary component 17 and the second sheet metal auxiliary component 18 are detachably installed on the sheet metal processing platform 2 or on two adjacent sheet metal support components 5 using pins. Then, the sheet metal 10 to be spliced ​​is placed into the lifting positioning pin 14, and the sheet metal, the first sheet metal auxiliary component 17, and the second sheet metal auxiliary component 18 are welded together, thus achieving the splicing of any sheet metal. The welding anti-adhesion components 19 and 20 are provided below the sheet metal auxiliary connection device 9 to prevent adhesion and deformation during sheet metal welding. Figure 8 The diagram shows the welding of the first plate auxiliary component 17 and the second plate auxiliary component 18 to the plate 10. The first plate auxiliary component 17 and the second plate auxiliary component 18 are integrally formed.

[0039] Furthermore, the second side of the plate processing platform 2 is provided with a plate loading port, and a safety light curtain device 4 is installed inside the plate loading port. The installation of the safety light curtain device 4 makes welding safer and avoids the risk of human approach.

[0040] Specifically, the safety light curtain device 4 includes a light curtain transmitter and a light curtain receiver. The light curtain transmitter and the light curtain receiver work together to form a safety light curtain. When a person approaches and triggers the safety light curtain, the machine stops working, ensuring safety and reliability.

[0041] Furthermore, the machine body 1 is equipped with a control device for controlling the operation of the plate welding robot 3, the plate first positioning device 6, and the plate second positioning device 7.

[0042] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other modifications under the guidance of the present invention without departing from the spirit and scope of the claims. All of these modifications are within the scope of protection of the present invention.
