Description

Technical Field

[0001] This utility model relates to the field of metal coil processing, and in particular to a strip welding device. Background Technology

[0002] In modern industrial production, automated welding lines are widely used in various fields, such as automobile manufacturing and electronic equipment production, due to their high efficiency and precision welding capabilities. Automated welding lines can significantly improve production efficiency, reduce labor costs, and ensure the stability of welding quality.

[0003] However, traditional automated welding lines face a significant challenge during operation: material changeover. When the strip runs out and needs to be replaced, the machine typically needs to be stopped. This not only interrupts the production process and reduces efficiency but can also negatively impact welding quality. Frequent downtime for material changes also increases equipment wear and maintenance costs, affecting the overall stability and reliability of the production line. Utility Model Content

[0027] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0028] like Figures 1 to 4 As shown, a preferred embodiment of this utility model provides a strip welding device, including a base 2, a limiting component 4 mounted on the base 2, and a welding component. The limiting component 4 includes a support plate 41 for supporting the strip 3 to be welded, a positioning element detachably mounted on the support plate 41 for positioning the strip 3 to a preset welding position, and a pressure plate 42 detachably mounted on the support plate for fixing the strip 3. The welding component is used to weld the strip 3, which is positioned by the positioning element and fixed by the pressure plate 42. In this embodiment, the strip welding device is mainly used to weld the ends of two strips 3 together. The positioning element and the limiting component 4 achieve a precise connection between the two strips 3, completing a seamless feeding process and avoiding feeding interruption due to the depletion of the strip 3, thereby ensuring that the equipment can continue welding without stopping.

[0029] Specifically, the strip welding device also includes a body 1, which is a rectangular structure used to support the base 2 and the components mounted on the base 2. A cavity is provided in the middle of the body 1, and a laser host and an industrial control computer for driving the welding components are installed inside the cavity. A door panel is installed on the body 1 in an openable manner to enclose the laser host and the industrial control computer. The bottom of the body 1 is equipped with multiple casters for moving the strip welding device and multiple disc feet for fixing the body 1.

[0030] In this embodiment, the support plate 41 is fixedly welded to the base 2. The limiting component 4 also includes a pin 45 mounted on one end of the support plate 41. One end of the pressure plate 42 is rotatably mounted on the support plate 41 via the pin 45. Specifically, there are two pressure plates 42, with a gap between them for welding components. Correspondingly, the support plate 41 has a groove that corresponds to the gap between the pressure plates 42. When the welding components are welding, the welding laser passes through the gap to weld the strip 3 fixed on the support plate 41.

[0031] Specifically, the height of the middle part of the bearing plate 41 is lower than the height of the end part, so as to prevent the material strip 3 from being squeezed when the pressure plate 42 is closed on the bearing plate 41.

[0032] In this embodiment, when the support plate 41 and the pressure plate 42 are closed, to prevent the pressure plate 42 and the support plate 41 from shaking during the welding process, which could lead to a deviation in the welding position, the limiting component 4 further includes a locking mechanism 44 installed at the other end of the support plate 41 and a locking hole opened at the other end of the pressure plate 42 for engaging with the locking mechanism 44. In this embodiment, the locking mechanism 44 is specifically a pin fixed to one end of the support plate 41. When the pressure plate 42 and the support plate 41 are fixed, the pin is inserted into the locking hole to fix the pressure plate 42. In other embodiments, the locking mechanism 44 can be any structure capable of fixing the pressure plate 42 to the support plate 41.

[0033] In this embodiment, the positioning element is a positioning pin 43 that is detachably mounted on the surface of the support plate 41. When the strip 3 is being welded, there are separators on the strip 3 for separating the workpieces. The separators have through holes. The positioning pins 43 pass through the through holes to position the strip 3 mounted on the support plate 41. Multiple positioning pins 43 are mounted on the support plate 41 and are arranged linearly.

[0034] Specifically, the limiting component 4 also includes a pressure block 46 mounted on the pressure plate 42, with a clearance hole on the pressure block 46. When the pressure plate 42 is closed relative to the support plate 41, the positioning pin 43 passes into the clearance hole, which does not hinder the continued closing of the pressure plate 42, thereby compacting the product. Because the positioning pin 43 is mounted on the support plate 41, in order to prevent the length of the positioning pin 43 from being insufficient to compact the product, a pressure block 46 is mounted on the pressure plate 42. The pressure block 46 is strip-shaped and is mainly mounted on the contact surface between the product and the pressure plate 42. The pressure block 46 has a clearance hole. When the pressure plate 42 is closed relative to the support plate 41, the positioning pin 43 passes into the clearance hole, thereby compacting the product.

[0035] In this embodiment, the positioning pin 43 is mounted on the support plate 41, the strip 3 is placed on the support plate 41 and positioned by the positioning pin 43. After positioning, the pressure plate 42 and the support plate 41 are closed to fix the strip 3. The welding assembly passes through the gap between the two pressure plates 42 to weld the fixed strip 3.

[0036] Specifically, in this embodiment, the positioning pins 43 installed on the inner side of the pressure plate are preferably in three rows, and the corresponding pressure blocks 46 are also installed in three strips. The two strips 3 are fixed by two pressure plates 42 respectively. One strip 3 is fixed to one side of the support plate 41 by the positioning pins 43, with the groove on the support plate 41 as the dividing point. The other strip 3 is fixed to the other side of the support plate 41. Then the pressure plate 42 closes to weld the two strips 3, so that the material supply is not interrupted due to the depletion of the strip 3 in the automated welding line, thereby ensuring that the equipment can continue to perform welding work without stopping the machine.

[0037] In this embodiment, the welding assembly includes a bracket 5 mounted on the base 2, a focus adjustment mechanism 8 mounted on the bracket 5, a laser lens 7 for welding the strip 3, and a connecting plate 6 for connecting the focus adjustment mechanism 8 and the laser lens 7. The bracket 5 is fixed on the base 2, and the laser lens 7 is mounted directly above the limiting assembly 4. After the limiting assembly 4 is fixed, the laser lens 7 welds the strip 3.

[0038] In this embodiment, the laser lens 7 is fixed to the focus adjustment mechanism 8 via the connecting plate 6. The focus adjustment mechanism 8 is vertically mounted on the bracket 5.

[0039] In this embodiment, the welding assembly also includes a galvanometer module 9 mounted on the top of the laser lens 7 for splitting the laser lens 7. The galvanometer module 9 is fixed to the focus adjustment mechanism 8 via a connecting plate 6. The connecting plate 6 is specifically a rectangular plate, with one end fixed to the focus adjustment mechanism 8 and the other end fixedly connected to the laser lens 7 and the galvanometer module 9.

[0040] In this embodiment, the welding assembly also includes an optical fiber connector 10 mounted on the galvanometer module 9 for connecting optical fibers. One end of the optical fiber bundle is connected to the laser host installed inside the body 1, and the other end is connected to the galvanometer module through the optical fiber connector. When the focus adjustment mechanism 8 adjusts the focus, the length of the optical fiber bundle changes as the connecting plate 6 moves up and down with the galvanometer module 9 and the laser lens.

[0041] In this embodiment, the strip welding device further includes a controller for controlling the laser lens 7 to perform welding, which is communicatively connected to the galvanometer module 9 and the laser lens 7. The controller is mounted on the machine body 1. Specifically, in this embodiment, the controller is a start button. After the limiting component 4 fixes the strip 3, pressing the start button initiates the welding of the strip 3 by the laser lens 7.

[0042] The strip welding device provided in the embodiments of this application uses positioning pins 43 to accurately position two strips 3 on the support plate 41, and combines them with pressure plate 42 to press the strips 3 together. Then, the strips 3 are welded together by laser lens 7, realizing the precise connection of the two strips 3 and completing the seamless feeding process. This avoids the interruption of feeding due to the depletion of strips 3, thereby ensuring that the equipment can continue to perform welding work without stopping.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
