Abstract
Description
Technical Field
[0001] This utility model relates to silver brazing technology, and in particular to a silver brazing tape feeding device. Background Technology
[0002] In the silver brazing process, the accuracy and stability of the silver brazing strip feeding directly affect the welding quality and production efficiency. Currently, existing silver brazing strip feeding devices have the following technical problems:
[0003] Poor adaptability of the feeding tray and low material change efficiency: Existing devices mostly use fixed integrated feeding trays. When it is necessary to change to silver strips of different specifications (such as width and thickness), the feeding assembly needs to be completely disassembled. The disassembly and assembly steps are cumbersome and time-consuming, which seriously affects the continuity of production.
[0004] Insufficient conveying stability and easy deviation: The silver brazing strip is relatively thin, and the existing conveying structure lacks an effective horizontal guiding mechanism. The silver brazing strip is prone to left and right deviation during the conveying process, which leads to inaccurate positioning of subsequent welding, and may even cause the silver brazing strip to bend or be scrapped.
[0005] Low feeding accuracy and lack of length control: Most devices do not have precise output length measuring components and rely on manual experience to judge the feeding amount, which easily leads to problems such as feeding too long or too short. This not only wastes materials but also causes unstable welding joint quality.
[0006] Silver brazing strips are easily damaged, affecting processing quality: The surface finish of silver brazing strips is required to be high. The material guiding components of existing equipment are mostly made of metal and have no buffer structure. When the silver brazing strip is in direct hard contact with the material guiding components, scratches and indentations are easily generated, which damages the surface integrity of the silver brazing strip and thus affects the welding effect.
[0007] Poor coordination between feeding and processing: The existing equipment has poor coordination between the feeding power and the subsequent welding process, often resulting in feeding interruptions or silver brazing strip accumulation, which leads to a decrease in production efficiency and cannot meet the continuous operation requirements of automated production lines.
[0008] In view of the shortcomings of the existing technology, there is an urgent need to design a silver brazing strip feeding device that is highly adaptable, stable in conveying, highly accurate, and can protect the quality of the silver brazing strip, so as to solve the above technical problems. Utility Model Content
[0009] The purpose of this utility model is to overcome the defects in the existing technology and provide a silver brazing strip feeding device. By optimizing the feeding, guiding and extracting structure, it solves the problems of difficult material replacement, deviation, low accuracy, easy damage to silver brazing strip and poor connection in the existing device, and realizes the automated, precise and stable conveying of silver brazing strip.
[0010] To achieve the above and other related objectives, the technical solution provided by this utility model is: a silver wire feeding device, comprising:
[0011] The feeding mechanism consists of a motor, a rotating shaft, and a feeding disc. The feeding disc is detachably mounted on the rotating shaft. The motor drives the rotating shaft to rotate, thereby causing the feeding disc to rotate.
[0012] The material guiding mechanism consists of roller group one, roller group two and a sensor. Roller group one and roller group two are arranged opposite to each other to form a guiding structure to guide the silver strip on the feeding tray to be discharged horizontally. The sensor is located between roller group one and roller group two and is used to measure the discharge length of the silver strip.
[0013] The material extraction mechanism consists of a drive module and a gripper module. The drive module is used to drive the gripper module to reciprocate along the silver strip discharge direction, and the gripper module is used to clamp or release the silver strip.
[0014] A preferred technical solution is as follows: it further includes a guide trough, which is located on the bottom side of the feeding tray. The guide trough is used to pre-store the silver brazing strip delivered by the feeding mechanism and to guide the silver brazing strip to the guide mechanism.
[0015] The preferred technical solution is that the bottom of the feed trough is provided with a buffer pad, and the buffer pad is correspondingly arranged with the silver brazing strip.
[0016] The preferred technical solution is as follows: the first roller group and the second roller group have the same structure, each including a first roller and a second roller. The first roller and the second roller are arranged opposite each other and can rotate freely. A channel is reserved between the first roller and the second roller for the silver brazing strip to pass through.
[0017] The preferred technical solution is as follows: the drive module consists of a mounting plate, a guide rail, a slide block, a lead screw, a lead screw nut, and a motor. The guide rail is fixedly mounted on the mounting plate along the silver strip discharge direction. The slide block slides on the guide rail. The lead screw is mounted on the mounting plate and is arranged parallel to the guide rail. The lead screw nut is screwed onto the lead screw and is fixedly connected to the slide block. The motor is fixed on the mounting plate and is used to drive the lead screw to rotate.
[0018] The preferred technical solution is as follows: the gripper module consists of a gripper cylinder and grippers, the gripper cylinder is fixed on the slide and is used to drive the grippers to grip or release the silver strip.
[0019] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:
[0020] Improved material change efficiency and strong adaptability: The feeding tray can be detachably mounted on the rotating shaft. When changing to different specifications of silver brazing strip, there is no need to disassemble the entire feeding mechanism. Just remove the old feeding tray and put on the new feeding tray. The material change time is reduced by more than 60%. It can be adapted to silver brazing strips of various widths and thicknesses.
[0021] Stable and precise conveying: Roller group one and roller group two are set opposite each other to form a horizontal guide channel, forcing the silver strip to be conveyed along the preset path, effectively avoiding deviation; the sensor measures the output length in real time, which can control the feeding accuracy within ±0.5mm, solving the problem of low accuracy of manual control and reducing material waste.
[0022] Protecting the quality of the silver brazing strip and reducing the scrap rate: The buffer pad at the bottom of the feed trough and the free-rotating structure of the roller assembly avoid hard friction and impact between the silver brazing strip and the metal parts. The surface scratch rate of the silver brazing strip is reduced from 25% in the existing technology to less than 3%, ensuring the integrity of the silver brazing strip before welding.
[0023] Achieving continuous conveying with good connectivity: The material extraction mechanism drives the gripper module to reciprocate through the drive module. When the gripper holds the silver brazing strip, it is simultaneously conveyed to the welding station. When released, it returns to the initial position to re-grip, forming a continuous cycle of "conveyance-return-reconveyance". This avoids material interruption or accumulation and improves the efficiency of connection with automated welding production lines by more than 40%.
[0024] Simple structure and easy maintenance: The modular design of each mechanism and the simple connection of components allow for individual replacement of damaged parts during later maintenance, reducing maintenance costs and downtime. Attached Figure Description
