Description

Technical Field

[0001] This utility model relates to the technical field of welding equipment, specifically a continuous automatic welding machine for irregular surfaces. Background Technology

[0002] With the continuous improvement of industrial automation, automatic welding equipment has been widely used in hardware processing and other production fields. Automated welding equipment can replace manual labor, thereby achieving standardization and automation of the welding process, thus improving production efficiency, ensuring welding quality and reducing labor intensity.

[0003] Traditional automatic welding equipment is typically used to process flat or regularly curved workpieces, and is often equipped with a welding head in only one direction, severely limiting its freedom of movement. When welding irregular curved surfaces or multiple surfaces, the difficulty in flexibly adjusting the angle and position of the welding points prevents full coverage of all welding areas, requiring more complex programming or tooling. For example, for simultaneous top and side welding, multiple clamping operations or manual intervention for positioning are necessary, making continuous automatic welding in a single clamping operation difficult. Furthermore, to weld multiple surfaces or curved surfaces, the welding head needs to move complexly, extensively, and frequently in three-dimensional space. The fixtures for positioning the workpiece also need to move synchronously to match the welding process. This multi-degree-of-freedom motion welding requires a high-current energy supply. Traditional cables are prone to insulation wear under splicing, large-angle bending, and stretching, resulting in a high failure rate, long service life, and increased equipment maintenance costs and downtime.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings. A continuous automatic welding machine for irregular surfaces includes a main frame 1 and a fixed frame 10 connected above the main frame 1. A welding mechanism is movably installed within the fixed frame 10, and the welding mechanism includes a welding head 2 and a welding drive device 5.

[0037] It also includes two mounting frames 11, with a gap between the two mounting frames 11 to form a welding station 12, and the welding mechanism is located above the welding station 12; a fixture 13 and a fixture driving device 3 are installed in the welding station 12, and the fixture driving device 3 drives the fixture 13 to rise into the working range of the welding mechanism, and the welding mechanism welds the workpiece placed in the fixture 13.

[0038] A slide rail device 6 is installed on the outside of the fixed frame 10. The bottom of the slide rail device 6 extends and connects to the welding drive device 5. A transverse soft connection device 8 is provided on the other side of the slide rail device 6. The welding drive device 5 drives the welding head 2 to move laterally within the fixed frame 10. The slide rail device 6 simultaneously drives the transverse soft connection device 8 to perform transverse stretching.

[0039] A longitudinal flexible connection device 7 is also installed on the outside of the fixed frame 10. The longitudinal flexible connection device 7 is connected to the welding drive device 5. The welding drive device 5 drives the welding head 2 to move longitudinally within the fixed frame 10, and simultaneously drives the longitudinal flexible connection device 7 to perform longitudinal stretching.

[0040] The fixture 13 is equipped with a lower flexible connection device 9 on one side. The fixture driving device 3 drives the fixture 13 to move longitudinally within the welding station 12, and simultaneously drives the lower flexible connection device 9 to perform longitudinal stretching.

[0041] like Figure 1-3 The aforementioned spot welding includes a fixed frame connected to the top of the main frame, to which the welding mechanism can be movably installed. It also includes two mounting frames with a gap between them forming a welding station for welding and positioning. A fixture is built into this welding station, while the welding mechanism is positioned above it. A fixture drive device first moves the fixture, which has already clamped the workpiece, upwards, transferring the fixture into the working range of the welding mechanism. Then, the welding mechanism performs the welding operation on the workpiece.

[0042] The welding mechanism includes a welding head and a welding drive device that drives the welding head. The welding drive device can drive the welding head to move laterally left and right within a fixed frame. To maintain power and signal connection during movement, a slide rail device is installed outside the fixed frame and is linked to the welding drive device. When the welding head moves laterally, it simultaneously drives the slide rail device to move, and a lateral flexible connecting device installed on one side of the slide rail device simultaneously stretches or contracts laterally.

[0043] Similarly, a longitudinal flexible connection device is also installed on the outside of the fixed frame. When the welding drive device drives the welding head to move up and down in the longitudinal direction inside the fixed frame, it simultaneously drives the longitudinal flexible connection device to stretch or tighten in the longitudinal direction.

[0044] Similarly, the fixture drive device can drive the welding head to move up and down in the longitudinal direction at the welding station. In order to maintain the connection of energy and signal during the movement, a lower soft connection device is provided on one side of the fixture. When the fixture drive device drives the fixture to move in the longitudinal direction, it simultaneously drives the lower soft connection device to stretch or tighten in the longitudinal direction.

[0045] Driven by the welding drive device, the welding head can move laterally and longitudinally, while the fixture can move longitudinally under the drive of the fixture drive device. Both the welding head and fixture possess multi-degree-of-freedom motion capabilities, enabling flexible multi-axis movement and providing sufficient support for welding irregularly shaped surfaces of workpieces. Furthermore, the workpiece undergoes continuous and automated cyclical operation throughout the clamping and welding process, welding multiple positions and angles on the irregularly shaped surfaces of the workpiece. This reduces inter-process transfers, waiting times, or manual intervention, significantly improving production efficiency and automation levels.

[0046] By introducing a horizontal flexible connection device, a vertical flexible connection device, and a lower flexible connection device, the traditional cable connection is replaced, avoiding power or signal instability or hard connection during the movement of moving parts, thus realizing continuous automatic welding operation of spot welding.

[0047] The welding head 2 includes a top welding head 21 and a side welding head 22, which are distributed around the top of the clamp 13;

[0048] The top welding head 21 is distributed horizontally in several units, and the side welding heads 22 are distributed gradually downwards in several units.

[0049] like Figure 4 As shown, the welding head includes several top welding heads and side welding heads, which are arranged together around the top of the fixture. The top welding heads are distributed laterally, while the side welding heads are distributed gradually downwards. This combination of welding heads, along with the use of the welding drive device, allows the welding head to approach the workpiece from different positions and angles. The spot welding machine can simultaneously weld the top plane, side, or other possible inclined surfaces of the workpiece. The spot welding machine effectively welds weld points located on the top, side, and inclined surfaces, improving the coverage area and adaptability of the spot welding machine to complex workpieces, and increasing welding efficiency.

[0050] The welding drive device 5 includes a side drive device 57, and the side welding head 22 is connected below the side drive device 57. The side drive device 57 includes a side drive cylinder 571 and a side push rod 572. The side drive cylinder 571 drives the side push rod 572 to push outward, thereby causing the side welding head 22 to extend and realize the side welding of the workpiece. A side copper busbar 573 is installed on one side of the side welding head 22.

[0051] like Figure 4 As shown, the welding drive device includes a dedicated side drive unit for driving the side welding heads. Each side welding head is connected below the side drive unit and operates via a side drive cylinder that drives a side push rod. When the side drive cylinder starts working, it pushes the side push rod towards the workpiece, causing the side welding head to extend and contact the side of the workpiece for welding. The structure is clear, and the motion principle is simple and straightforward, facilitating user control and implementation of the welding operation. A side copper busbar is also installed on one side of the side welding head. This busbar conducts the large current required for the welding process to the side welding head. The dedicated side copper busbar provides a dedicated current path closer to the side welding head, helping to ensure the stability and efficiency of current transmission during side welding.

[0052] The welding drive device 5 further includes a longitudinal cylinder 51 and a longitudinal push rod 52. The top welding head 21 is connected to the longitudinal push rod 52 through a cylinder plate 58. The longitudinal cylinder 51 drives the longitudinal push rod 52 to move up and down, thereby realizing the longitudinal movement of the top welding head 21.

[0053] It also includes a cylinder seat 53 and a transverse connecting rod 54. The cylinder seat 53 is fitted outside the longitudinal cylinder 51, and the transverse connecting rod 54 is installed across the cylinder seat 53 at the four corners of the cylinder seat 53.

[0054] It also includes a transverse cylinder 55 and a transverse push rod 56. The transverse push rod 56 is connected to one side of the cylinder seat 53. The transverse cylinder 55 drives the transverse push rod 56 to move left and right, thereby realizing the transverse movement of the top welding head 21.

[0055] like Figure 4 As shown, the welding drive device includes a longitudinal cylinder and a longitudinal push rod specifically for welding the top welding head. The longitudinal cylinder drives the longitudinal push rod to move up and down in the longitudinal direction, thereby causing the top welding head to extend. The top welding head can contact the top of the workpiece, thereby performing the welding process in the vertical longitudinal direction of the top welding head. The structure is clear, the motion principle is simple and clear, and it is convenient for users to realize and control the welding operation.

[0056] Furthermore, a cylinder seat is fitted around the longitudinal cylinder, and the cylinder seat is connected as a whole by a transverse connecting rod. The outermost side of the cylinder seat is installed on the transverse push rod side, and the connecting rod drives the entire cylinder seat to move laterally within the fixed frame. When the transverse cylinder drives the transverse push rod to move left and right in the transverse direction, the welding head moves horizontally left and right under the push of the cylinder seat. Users can adjust the left and right movement according to the actual welding point position, which is suitable for welding workpieces of various sizes and expands the practicality of the spot welding machine. The transverse connecting rod is installed at the four corners of the cylinder seat, which plays a role in stabilization, guidance and structural reinforcement.

[0057] The top welding head is independently given the ability to move in the lateral and longitudinal directions, allowing it to be positioned more precisely at the top of the workpiece for welding at different angles or positions. Different cylinders control the movement in different directions, resulting in a clear structure that is easy to control and achieve the desired motion.

[0058] The slide rail device 6 includes a fixed slide rail 61 installed on the outside of the fixed frame 10 and a movable slider 62 assembled therewith. The movable slider 62 extends to the bottom of the fixed frame 10 and is provided with a transverse connecting seat 63. The transverse connecting seat 63 is installed at the bottom of the cylinder seat 53. The top welding head 21 slides laterally, driving the movable slider 62 to move along the fixed slide rail 61. The transverse soft connecting device 8 is stretched laterally.

[0059] An installation plate 64 is provided across the outer side of the movable slider 62, and the transverse flexible connection device 8 and the longitudinal flexible connection device 7 are installed on the installation plate 64.

[0060] like Figure 6 , 7 As shown, the fixed slide rail is connected to the outside of the fixed frame, and the bottom of the movable slider extends to the bottom of the fixed frame through the transverse connecting seat and is installed at the bottom of the cylinder seat. Therefore, when the top welding head moves laterally under the drive of the transverse cylinder, the movable slider will be driven to slide laterally along the fixed slide rail synchronously through the transverse connecting seat.

[0061] Furthermore, the movable end of the transverse flexible connector is mounted on a mounting plate located on the outside of the movable slider. When the movable slider slides laterally, it will simultaneously pull the transverse flexible connector to stretch or contract.

[0062] The longitudinal flexible connection device 7 includes a longitudinal copper busbar 71 and a cylinder aluminum plate 72, wherein the cylinder aluminum plate 72 is fixed below the cylinder plate 58;

[0063] One end of the longitudinal copper busbar 71 is mounted on the mounting plate 64, and the other end of the longitudinal copper busbar 71 extends to the bottom of the fixing frame 10 and is mounted on the cylinder aluminum plate 72.

[0064] like Figure 6 , 7 As shown, the longitudinal flexible connection device includes a longitudinal copper busbar and a cylinder aluminum plate. The movable end of the longitudinal copper busbar is fixedly installed below the cylinder plate via the cylinder aluminum plate, while the fixed end of the longitudinal copper busbar is installed on the mounting plate. When the top welding head moves longitudinally under the drive of the longitudinal cylinder, the cylinder aluminum plate will synchronously pull the longitudinal copper busbar to stretch or contract. The longitudinal copper busbar utilizes the characteristics of its flexible copper sheet to provide a specific and stable longitudinal flexible connection, providing stable transmission of energy and signals required for the longitudinal movement of the top welding head.

[0065] The horizontal flexible connection device 8 includes a horizontal copper busbar 81 and a connecting frame 82. The connecting frame 82 is mounted on the main frame 1. One end of the horizontal copper busbar 81 is mounted on the connecting frame 82, and the other end of the horizontal copper busbar 81 is connected to the mounting plate 64.

[0066] like Figure 6 , 7 As shown, the lateral flexible connection device includes a lateral copper busbar and a connecting frame. The fixed end of the lateral copper busbar is mounted on the main frame through the connecting frame, while the movable end of the lateral copper busbar is mounted on the mounting plate set on the outside of the movable slider. When the movable slider slides laterally, it will simultaneously pull the lateral copper busbar to stretch or contract. The lateral copper busbar utilizes the characteristics of its flexible copper sheet to provide a specific and stable lateral flexible connection, providing stable transmission of energy and signals required for the lateral movement of the top welding head.

[0067] The clamp driving device 3 includes a clamp push rod 31 and a clamp cylinder 32 installed below the clamp 13. The clamp push rod 31 extends longitudinally, and the clamp cylinder 32 drives the clamp push rod 31 to move up and down, thereby driving the clamp 13 to move in the longitudinal direction.

[0068] like Figure 4As shown, the fixture driving device includes a fixture push rod and a fixture cylinder installed below the fixture. The fixture push rod extends longitudinally and is directly connected to the fixture. The fixture cylinder pushes the fixture push rod to move up and down, which in turn moves the fixture longitudinally, thereby realizing the lifting and lowering of the fixture and allowing the workpiece to enter the working range of the welding mechanism for welding operations.

[0069] The lower flexible connection device 9 includes a connecting plate 91 connected to one side of the clamp 13 and a lower copper busbar 92 installed on the connecting plate 91. The other end of the lower copper busbar 92 is connected to the main frame 1 through the clamp connecting plate 93.

[0070] like Figure 3 , 6 As shown, the lower flexible connection device includes a lower copper busbar, a clamp connecting plate, and a connecting plate. The fixed end of the lower copper busbar is mounted on the main frame through the clamp connecting plate, while the movable end of the lower copper busbar is connected through the connecting plate clamp. When the clamp moves in the longitudinal direction, it will simultaneously pull the lower copper busbar to stretch or contract. The lower copper busbar utilizes the characteristics of its flexible copper sheet to provide a specific and stable longitudinal flexible connection, providing stable transmission of energy and signals required for the longitudinal movement of the clamp.

[0071] The horizontal copper busbar 81, the vertical copper busbar 71, the lower copper busbar 92, and the side copper busbar 573 are composed of several layers of copper sheets stacked together.

[0072] The horizontal copper sheets, vertical copper sheets, lower copper busbar, and side copper busbars are composed of several layers of stacked copper sheets. This stacked copper sheet structure allows the copper busbar to maintain sufficient conductive cross-sectional area while also possessing good flexibility, enabling it to withstand repeated bending without easily fatigued and breaking. This significantly improves the flexibility and fatigue resistance of the copper busbar, making it ideal for applications requiring large-scale, high-frequency lateral, longitudinal, and lifting movements, greatly extending its service life and improving equipment reliability. Secondly, while ensuring flexibility, the required high current carrying capacity can be achieved by stacking a sufficient number of copper sheets. The multi-layer structure also facilitates heat dissipation, ensuring stable and reliable transmission of high currents or control signals, significantly reducing faults or maintenance caused by traditional cables, lowering maintenance costs, and ensuring stable welding quality.

[0073] Working Principle: In this spot welding machine, the welding mechanism includes a welding head and a welding drive device that drives it. The welding head comprises a top welding head distributed laterally and side welding heads that gradually slope downwards. This composite multi-head distribution adapts to the welding requirements of different positions and angles of the workpiece. Furthermore, the side welding heads are equipped with independent side drive devices for independent driving, while the top welding head can move independently in both lateral and longitudinal directions with the cooperation of lateral and longitudinal cylinders. Combined with the multi-axis drive of the welding heads by the welding drive device, the spot welding machine can approach the irregularly shaped surfaces of the workpiece from different angles and positions, effectively welding weld points located on the top, sides, and even inclined surfaces. This greatly improves the welding adaptability and coverage integrity of complex-shaped workpieces, overcoming the problem of existing technologies being unable to fully weld irregularly shaped surfaces.

[0074] To address the shortcomings of traditional cables, such as unstable transmission and easy wear, this project uses a horizontal flexible connection device, a vertical flexible connection device, a lower flexible connection device, and side copper busbars to replace cable connections. The copper sheets are made of several layers of copper sheets stacked together, possessing excellent conductivity, heat dissipation, bending resistance, and strong fatigue resistance. The flexibility of the copper sheets enables the spot welding machine to stably and reliably transmit large currents or control signals in a wide range of high-frequency horizontal, vertical, and lifting movements, significantly reducing the failure rate and maintenance costs caused by connection cable problems, and ensuring the stability of welding quality.

[0075] Furthermore, the ingenious structure, through the combination of the slide rail device with the transverse and longitudinal flexible connection devices, improves the precision and stability of the movement, ensuring the synchronization of the movement of the welding head with the transverse and longitudinal copper busbars, and the reliable and stable connection between them.

[0076] Driven by the clamp drive device, the fixture automatically rises to the working range of the welding mechanism to perform spot welding. After the spot welding process is completed, it automatically descends and resets to wait for the next process. In coordination with the welding mechanism, it continuously and automatically completes welding processes at multiple positions and angles on the irregular surface of the workpiece, reducing the workpiece's movement, waiting or manual intervention, significantly improving production efficiency and automation level, and realizing a higher degree of automation and continuous welding. Therefore, it can be widely promoted.

[0077] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
