Description

Technical Field

[0001] This utility model relates to the field of soft copper bar welding technology, and in particular to a vision positioning component and an automated soft copper bar welding equipment. Background Technology

[0002] Soft copper brazing is a conductive component made from high-purity soft copper, primarily used for current transmission and distribution in electrical equipment. Its advantages include: high ductility, facilitating processing into complex shapes; excellent conductivity and low resistivity, reducing energy loss; and better resistance to vibration and thermal expansion compared to hard copper, lowering the risk of cracking. It is widely used in transformers, switchgear, rail transportation, and other applications requiring high-current connections, making it a key material for ensuring the stable operation of power systems.

[0003] When processing soft copper bars, welding equipment is required. However, most existing welding equipment uses a semi-automatic manual feeding method, which is inefficient. Therefore, a vision positioning component and an automated welding equipment for soft copper bars are proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing welding equipment, which mostly uses semi-automatic manual feeding and has low efficiency when welding soft copper bars. This invention proposes a vision positioning component and an automated welding equipment for soft copper bars.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A visual positioning component, comprising:

[0007] Gantry frame;

[0008] The mounting plate is fixed to one side of the gantry frame, and the camera is mounted on its bottom.

[0009] The controller is electrically connected to the camera;

[0010] A sliding bracket is slidably connected to one side of the mounting plate;

[0011] Three mounting brackets are fixed to both ends and one side of the sliding frame, respectively. Each mounting bracket has a push plate fixed to its bottom, and the bottom of the push plate is provided with an inclined surface for guiding the alignment of the raw materials.

[0012] The second cylinder is fixed to one side of the mounting plate, and its piston rod is connected to the sliding frame to drive the push plate to rise and fall.

[0013] The camera captures the position information of the raw material, and the controller uses this information to control the second cylinder to drive the push plate to adjust the position of the raw material by means of an inclined plane.

[0014] An automated welding device for soft copper bars includes the aforementioned vision positioning component, and:

[0015] The frame, wherein the gantry is fixed to the top of the frame;

[0016] The conveying assembly includes two conveying rollers rotatably connected to both sides of the frame and multiple conveyor belts connected by a drive mechanism;

[0017] The placement mechanism includes a base plate fixed between the conveyor belts, a placement platform on the base plate, a positioning groove and a limiting plate formed on the placement platform;

[0018] The welding execution assembly includes a slide plate slidably connected to the gantry, an ultrasonic welding machine fixed to the bottom of the slide plate, and a first cylinder that drives the slide plate to lift and lower.

[0019] The limiting plate restricts one side of the raw material, and after the push plate is inserted into the positioning groove to adjust the position of the raw material, the ultrasonic welding machine performs welding.

[0020] As a further improvement to the above technical solution:

[0021] A telescopic rod is fixed to the bottom of the slide plate, and a pressure plate is connected to the bottom of the telescopic rod. A spring is sleeved on the telescopic rod. When the slide plate descends, the pressure plate presses the raw material and the spring adaptively adjusts the pressing force. A stepper motor is fixed to one side of the frame, and its output shaft is connected to a conveyor roller to drive the conveyor belt to feed intermittently, so that the raw material passes under the vision positioning component and the welding execution component in sequence. A support plate is fixed between the two sides of the frame. The support plate is located under the slide plate to support the placement platform. There are two ultrasonic welding machines, symmetrically arranged at the bottom of the slide plate to weld the two sides of the raw material simultaneously. The pressing surface of the pressure plate is parallel to the surface of the placement platform. The elastic coefficient of the spring is configured to provide a pressing force of 5-10N. The width of the positioning groove is 0.5-1mm larger than the thickness of the push plate. The height of the limiting plate is 1.2-1.5 times the thickness of the raw material.

[0022] In this application, when welding copper flexible connectors to nickel sheets, a robotic arm loads the prepared raw materials, which fall onto a placement table. A stepper motor then starts, driving the conveyor rollers and conveyor belt to rotate, thus moving the raw materials one unit at a time. As the raw materials pass under a camera, the camera captures an image of their neatness, checking for proper placement. If neat, the materials are moved to the underside of the ultrasonic welding machine, and the first cylinder is activated. This cylinder moves a sliding plate downwards, causing the ultrasonic welding machine to contact the raw materials for welding. As the sliding plate falls, it also moves a telescopic rod and a pressure plate downwards, flattening the raw materials for easier welding and improved welding quality. If the raw materials are not neatly placed, a second cylinder is activated, moving a sliding frame, mounting frame, and push plate downwards. The inclined surface at the bottom of the push plate pushes the raw materials, making them neater, facilitating welding, improving finished product quality, and reducing defective products.

[0023] Beneficial effects: In this utility model, the visual positioning component and the automated welding equipment for soft copper bars, through the setting of the camera, enable the second cylinder to drive the sliding frame, mounting frame and push plate to move downward when the raw materials are not placed neatly. The inclined surface set at the bottom of the push plate pushes the raw materials, thereby making the raw materials more neat, facilitating welding, improving the quality of finished products and reducing defective products.

[0024] In this utility model, the visual positioning component and the automated welding equipment for soft copper bars, through the cooperation between the telescopic rod and the pressure plate, enable the telescopic rod and the pressure plate to move downward when the slide plate falls, and flatten the raw material by the pressure plate, which facilitates welding and improves the welding quality;

[0025] In this invention, when the raw materials are not placed neatly, the second cylinder can drive the sliding frame, mounting frame and push plate to move downwards. The inclined surface at the bottom of the push plate pushes the raw materials, making them more neat, facilitating welding, improving the quality of the finished product and reducing defective products. At the same time, when the slide plate falls, it also drives the telescopic rod and pressure plate to move downwards. The pressure plate flattens the raw materials, facilitating welding and improving welding quality. Attached Figure Description
