Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an automatic feeding device, in particular to a radium welding discharge device and a radium welding production line. Background Art

[0002] In modern manufacturing, laser welding technology is widely used in production lines of various products due to its high efficiency and precision. Laser welding, which uses laser as a heat source, can achieve high-quality welding results. However, in automated production lines, the efficiency of laser welding depends not only on the welding itself, but also on the upstream process, especially the discharge process.

[0003] In automated laser welding production lines, a four-axis manipulator is usually used to quickly place small parts into the laser welding jig for laser welding operations. Although this method improves the efficiency of material placement to a certain extent, it still has efficiency bottlenecks when dealing with high-precision and miniaturized parts. Specifically, in the process of picking and placing small parts, it is usually necessary to use a flexible vibration plate combined with a visual positioning system for precise picking. The complexity and time-consuming nature of this process greatly limits the cycle time of the entire production line.

[0004] The Chinese patent application number is 202111639314.2. A utility model. The utility model discloses a double-point automatic welding system with double-station loading and a working method, including a double-station pipe loading unit, a rod loading unit, a welding unit, a rod welding pushing unit, a pipe pushing unit, a welding support unit and a rod clamping unit. The double-station pipe loading unit is provided with pipes, the rod loading unit is provided with rods, the rod clamping unit can clamp the rods on the rod loading unit, the welding unit can weld rods and pipes on the welding support unit, and the rod welding pushing unit can push the welded parts on the welding support unit.

[0005] A dual-point automatic welding system with dual-station loading and a welding support unit mentioned in the working method may have limitations because it can only be used for welding rods and pipes of specific shapes, and cannot flexibly adapt to workpieces of different shapes. The discharge module design in the utility model is more flexible and can be applied to a variety of products.

[0006] Therefore, in order to improve the production efficiency of the entire automatic line and shorten the cycle time, it is urgent to develop a new radium welding unloading device that can complete the automatic unloading of small parts faster and more accurately. Utility Model Content

[0007] The utility model aims to solve the above problems in the prior art and proposes a radium welding discharge device and a radium welding production line.

[0008] The purpose of the utility model can be achieved through the following technical solutions: a radium welding discharge device, including an automatic line track, on which a number of jigs for carrying products are conveyed, a flexible vibration plate and a four-axis manipulator are arranged on one side of the automatic line track, a laser radium welder is arranged on the other side of the automatic line track, a double-station discharge mechanism is arranged between the four-axis manipulator and the laser radium welder, the double-station discharge mechanism is erected above the automatic line track, and the double-station discharge mechanism includes two relatively arranged discharge modules, and the discharge module has a transfer device and a discharge device.

[0009] Preferably, the unloading module includes an unloading seat arranged beside the automatic line track, a shift electric cylinder is arranged on the unloading seat, a shift frame is driven by the shift electric cylinder for translation, and two workstation plates are arranged relatively on the shift frame.

[0012] Preferably, the imitation platform is a T-shaped platform body, and the coarse positioning column and the fine positioning column are fixedly arranged on the horizontal platform surface of the T-shaped platform body.

[0013] Preferably, a guide rail is arranged on the rotating table, and a slider is correspondingly arranged on the loading rack, and the slider is embedded in the guide rail to form a sliding connection.

[0014] Preferably, a mounting hole is provided on the work station plate, a bearing is installed in the mounting hole, and a rotating shaft of the rotating motor penetrates the bearing to form a rotating connection.

[0015] Preferably, the two material carriers are arranged relative to each other to form a left-right symmetrical structure.

[0016] A radium welding production line comprises the above-mentioned radium welding discharge device.

[0017] Compared with the prior art, the radium welding discharge device and radium welding production line have the following beneficial effects:

[0018] 1. Improve the efficiency and accuracy of unloading: Through the use of the double-station unloading mechanism and the four-axis manipulator, continuous and fast unloading operation is achieved. This design allows small parts to be continuously supplied without stopping the machine, significantly reducing the production line stagnation time caused by waiting for unloading; in addition, the use of the shifting electric cylinder enables the station plate to be accurately translated to ensure the consistency and accuracy of each unloading position.

[0020] 3. Enhance the stability and reliability of operation: The combination of the rotary motor and lifting cylinder installed on the work station plate allows small parts to be turned over and positioned as necessary before unloading, ensuring that each small part can be accurately placed in the predetermined position in the fixture.

[0021] 4. Achieve precise positioning of small parts: The design of coarse and fine positioning columns not only improves the accuracy of material placement, but also reduces operational errors through the fool-proof function. This precise positioning greatly reduces the product defect rate and improves the quality of the final product.

[0022] 5. Adapt to various specifications of small parts: The T-shaped profiling table and positioning column design enable the device to adapt to small parts of different sizes and shapes, enhancing the versatility and flexibility of the equipment, thereby adapting to a wider range of production needs.

[0023] In general, the radium welding discharge device of the utility model not only improves production efficiency but also ensures high-quality production output through these innovative design improvements, providing an efficient, stable and economical solution for the manufacturing industry.

[0032] Preferably, the material discharge module includes a material discharge seat arranged beside the automatic line track 1, a shift electric cylinder 6 is arranged on the material discharge seat, a shift frame 7 is driven by the shift electric cylinder 6 for translation, and two workstation plates are arranged opposite to each other on the shift frame 7. The shift electric cylinder 6 drives the shift frame 7 to reciprocate, so that the two workstations alternately correspond to the four-axis manipulator 4, the fixture 2 and the product 3, thereby achieving the accuracy of material discharge.

[0033] like Figures 2 to 4 As shown, preferably, the material transfer device is a rotary motor 8 mounted on the work station plate, the rotary shaft of the rotary motor 8 is fixedly connected to the rotary table 9, and the material discharge device is a lifting cylinder 10 fixedly mounted on the rotary table 9, and the telescopic rod of the lifting cylinder 10 is fixedly connected to the material loading rack 11.

The positioning columns of different diameters are provided to prevent fooling, so as to prevent the small piece 12 from being placed upside down.

[0035] Preferably, the profiling table is a T-shaped table body, and the coarse positioning column and the fine positioning column are fixedly arranged on the transverse table surface of the T-shaped table body.
