Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and in particular to a metal wire round-head argon arc welding equipment. Background Technology

[0002] In kitchen equipment, especially those that automatically clean kitchen utensils, a dishwashing basket is typically included. This basket is composed of multiple metal wires woven into a mesh and arranged in a basket shape. Inside, several upright metal wires create partitions for categorizing and storing various kitchen utensils. To prevent these wires from cutting or scratching utensils or causing cuts to the user's hands during utensil handling, rounded ends are often welded to the tops of the upright wires to make them smooth. However, the manufacturing process of these wires presents several inconveniences. For example, current methods typically involve manually welding the wires using a welding torch on a workbench. This is extremely inefficient when welding large quantities, and the lack of dedicated equipment for batch fixing and alignment checks makes welding errors easy and increases the difficulty of the process. Furthermore, because the design of the metal wires on the dishwashing basket varies, each group of wires in different areas typically has a different height, making stable batch fixing and alignment checks even more challenging for the welding work. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a device that can vertically fix and position and align a batch of metal wires, perform automated welding, and have the function of adjusting the welding height.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] A metal wire round-head argon arc welding device includes a worktable, a welding torch for welding the round head to the top of the wire, a clamp for vertically placing several wires on the worktable, a limiter for limiting the opening and closing distance of the clamp, and a pneumatic device for driving the clamp to press the wires together. An electric support structure for controlling the protrusion height of the wires on the clamp is provided below the clamp. A detection structure for detecting the position of the top of the wires is also provided on the worktable. A robotic arm connected to the welding torch is provided on one side of the worktable, and a central control controller is also provided on one side of the worktable.

[0006] Furthermore, the clamping device of this utility model includes a fixed plate fixed to the top of the workbench by bolts, and a movable plate that can move linearly relative to the fixed plate. Several grooves for inserting wire are provided on the side wall of the fixed plate facing the movable plate.

[0007] Furthermore, the limiter in this utility model includes two symmetrically arranged limit members fixed to the rear side of the top of the workbench by bolts. Limit screws are connected to the limit members through screw holes, and there is space between the limit screws and the fixed plate for the movable plate to move.

[0008] Furthermore, the pneumatic device in this utility model includes a cylinder fixed to the rear side of the workbench, a connector is installed on the movable end of the cylinder, the connector is fixedly connected to the rear wall of the moving plate by bolts, and an electronic valve is installed at the air hole of the cylinder.

[0009] Furthermore, the electric support structure of this utility model includes a through groove disposed on the workbench and located below the groove, a support seat that can move vertically in the through groove is disposed in the through groove, an electric push rod is disposed below the support seat, the movable end of the electric push rod is connected to the bottom of the support seat, and a fixing frame for fixing the electric push rod is disposed at the bottom of the workbench.

[0010] Furthermore, the detection structure of this utility model includes a servo motor 1 disposed on both sides of the worktable, a protruding stud fixed on the rotor of the servo motor 1 and the protruding stud being disposed on the top of the worktable, a crossbar threadedly connected to the two protruding studs, a transverse groove provided on the crossbar and a transverse screw provided inside the transverse groove, a servo motor 2 for driving the transverse screw to rotate on one side of the transverse groove, a detection base that can move linearly within the transverse groove sleeved on the transverse screw, and a detection probe mounted on the detection base.

[0011] Furthermore, the central control controller in this utility model connects to an electronic valve, an electric push rod, a servo motor one, a servo motor two, and a robotic arm.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This invention utilizes a clamping device and a pneumatic mechanism to vertically clamp and fix multiple metal wires. A limiter restricts the pneumatic device's range of motion, and a detection structure monitors the top position of the metal wires. If the detected position is incorrect, the system can trigger an alarm on the central control controller or skip the process entirely. An electric support structure allows for simultaneous height adjustment of all metal wires, facilitating precise welding without altering the robotic arm's programming. Compared to traditional technologies, this solution provides a multi-functional device for welding round heads to the top of wires, offering automation, convenient fixing, and easy positioning.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 5 The present invention preferably provides a metal wire round-head argon arc welding device, including a worktable 1, a welding torch 2 for welding the round head to the top of the wire, a clamp 3 for vertically placing several wires, a limiter 4 for limiting the opening and closing distance of the clamp 3, and a pneumatic device 5 for driving the clamp 3 to press the wires together, an electric support structure 6 for controlling the protrusion height of the wires on the clamp 3 below the clamp 3, a detection structure 7 for detecting the position of the top of the wires on the worktable 1, a robotic arm 8 connected to the welding torch 2 on one side of the worktable 1, and a central control controller 9 on one side of the worktable 1.

[0021] The workbench, shaped like a table, supports the entire equipment and has a flat surface on top for placing various components. During operation, metal wire is loaded onto the clamp, and a pneumatic device clamps and secures the wire. An electric support structure adjusts the height of the wire, and a detection structure positions the top of the wire. If positioning is inaccurate, an alarm is triggered on the central control console, or welding is skipped. The welding process involves the central control console controlling a robotic arm to automatically clamp a ball to the top of the wire before welding. A welding torch can be mounted on the robotic arm, enabling it to perform welding as well as basic material movement. A limit switch restricts the movement distance of the pneumatic device. The central control console controls the clamp, electric support structure, detection structure, robotic arm opening and closing, and programming. The robotic arm can use suction or clamping to load round-headed components. The welding torch uses argon arc welding and is connected to a power source via wire.

[0022] The clamping device 3 described in this utility model includes a fixed plate 31 fixed to the top of the workbench 1 by bolts, and a movable plate 32 that can move linearly relative to the fixed plate 31. A plurality of grooves 33 for placing wire are provided on the side wall of the fixed plate 31 facing the movable plate 32. The fixed plate is in a fixed state, and the movable plate is in a movable state. When the movable plate moves closer to the fixed plate, the wire that has been vertically placed in the groove will be clamped.

[0023] The limiter 4 described in this utility model includes two symmetrically arranged limit members 41 fixed to the rear top of the worktable 1 by bolts. Limiting screws 42 are connected to the limit members 41 through screw holes. A space is left between the limiting screws 42 and the fixed plate 31 for the movable plate 32 to move. Since the limit members are fixed, rotating the limiting screws will cause them to move linearly along the limit members, thereby adjusting the distance between the limiting screws and the fixed plate, and changing the movable space of the movable plate. The limiter is designed to prevent the movable plate from moving too far when the cylinder contracts, which could lead to excessive impact force when the movable plate clamps.

[0024] The pneumatic device 5 described in this utility model includes a cylinder 51 fixed to the rear side of the workbench 1. A connector 52 is installed on the movable end of the cylinder 51. The connector 52 is fixedly connected to the rear wall of the moving plate 32 by bolts. An electronic valve 53 is installed at the air port of the cylinder 51. The cylinder is connected to an air compressor through the air port. The electronic valve is located at the air port and can be opened or closed by the central control console, which can control the extension and retraction of the cylinder. The movable end of the cylinder drives the connector, thereby allowing the moving plate to extend and retract.

[0025] The electric support structure 6 described in this utility model includes a through groove 61 disposed on the workbench 1 and located below the groove 33. A support seat 62 capable of vertical linear movement is disposed within the through groove 61. An electric push rod 63 is disposed below the support seat 62, and the movable end of the electric push rod 63 is connected to the bottom of the support seat 62. A fixing frame 64 for fixing the electric push rod 63 is disposed at the bottom of the workbench 1. The support seat can move up and down within the through groove by extending and retracting the electric push rod. Since the support seat serves as the bottom support for the wire, its vertical movement can control the protrusion length of the wire on the upper side of the clamp. The fixing frame is disposed at the bottom of the workbench and is used to fix the electric push rod.

[0026] The detection structure 7 described in this utility model includes a first servo motor 71 disposed on both sides of a workbench 1. A protruding stud 72 is fixed to the rotor of the first servo motor 71 and is located on the top of the workbench 1. A crossbar 73 is threaded onto the two protruding studs 72. A transverse groove 74 is provided on the crossbar 73, and a transverse screw 75 is provided inside the transverse groove 74. A second servo motor 76 is provided on one side of the transverse groove 74 to drive the transverse screw 75 to rotate. A detection base 77, which can move linearly within the transverse groove 74, is sleeved on the transverse screw 75. A detection probe 78 is mounted on the detection base 77. The detection structure is used to detect whether the top of each wire is in the welding position. The specific detection steps are as follows: before welding each wire, the first servo motor moves the crossbar up and down, and the second servo motor moves the detection base left and right, thereby allowing the detection probe on the detection base to move to a predetermined position to detect the end of the wire. The detection probe can use infrared sensors, photoelectric sensors, etc. to sense the top of the wire. When the detection shows that the top of the wire is not aligned, the signal is transmitted to the central control console. The central control console can use the program to make the robotic arm stop working or skip the welding of the current wire and detect and weld the next wire.

[0027] The central control controller 9 described in this utility model connects to the electronic valve 53, the electric push rod 63, the servo motor 71, the servo motor 76, and the robotic arm 8. The central control controller can utilize common programming software found in the prior art to control the robotic arm's movements, including the up-and-down movement of the electronic valve and the start-up timing and stroke of the servo motors 1 and 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
