[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention cooperates with the threaded rod, threaded block, vertical rod, positioning strip, first cleaning plate, second cleaning plate and arc plate. First, the automobile radiator core is placed on the surface of the reinforcement frame, the bottom surface of the core contacts the surface of the first cleaning plate, and the second cleaning plate is pushed downward manually, driving the vertical rod and the vertical frame to move downward inside the threaded block. After the bottom surface of the second cleaning plate contacts the surface of the core, one end of the positioning strip is embedded into the positioning hole and the concave hole, and the three are threadedly connected, so that the threaded block and the vertical frame can be limited and fixed.

[0020] 2. The present invention cooperates with the second servo motor, transmission rod, nozzle, water tank, water pump, guide plate and processing table. The cleaned core is manually pushed to the surface of the processing table, and the water pump is started. The water in the water tank will be guided along the water pipe to the inside of multiple nozzles, and then continue to be sprayed on the surface of the core. Spraying water can reduce the contact between the metal surface and the air, reduce the possibility of oxidation, thereby improving the joint strength and weld quality during core welding. Water spraying helps to provide a uniform moist environment for the core surface before welding, and helps to maintain the consistency of the temperature in the welding area. After the second servo motor is started, the transmission rod connected to its output shaft is driven to rotate, which also drives the processing table fixedly mounted thereon to rotate.

[0041] Step 3: After cleaning, the core is pushed to the surface of the processing table 22. As the water pump 26 is started, the water in the water tank is sprayed onto the surface of the core through multiple nozzles 25, thereby improving the quality of core cleaning;

[0042] Step 4: After the processing table 22 is tilted, the core slides onto the surface of the conveying roller 2 and is sequentially conveyed to the bottom of multiple welding heads 6.

[0043] Working principle and use process of the present invention: The automobile radiator core is the core part of the automobile radiator, which is usually made of metal and is responsible for heat dissipation. Its main function is to absorb the heat generated by the engine through the flowing coolant and take the heat away through the air outside the radiator, so as to maintain the normal working temperature of the engine. There are a series of coolant channels inside the radiator core, and the coolant flows through these channels to absorb the heat generated by the engine. The welding device is a device specially used for producing automobile radiator cores. The various components of the radiator core are welded by continuous welding technology. When the core is welded, the components are often placed directly on the bottom of the welding head 6. When the components of the radiator core are attached with dirt and dust, these impurities will affect the melting point of the welding material. The welding joint is not firm, which affects the performance of the radiator. The temperature of the welding area on the surface of the core is not stable enough, and the radiator parts are prone to deformation and cracking. For this reason, a continuous welding device for an automobile radiator core is designed. First, the automobile radiator core is placed on the surface of the reinforcement frame 9, and the bottom surface of the core contacts the surface of the first cleaning plate 17. The second cleaning plate 18 is pushed downward manually, driving the vertical rod 13 and the vertical frame 14 to move downward inside the threaded block 12. After the bottom surface of the second cleaning plate 18 contacts the surface of the core, one end of the positioning strip 15 is embedded into the positioning hole 16 and the inside of the concave hole. The three are threadedly connected, so that the threaded block 12 and the vertical frame 14 can be limited and fixed. After starting the first servo motor 11, it drives the vertical rod 13 and the vertical frame 14 to move downward inside the threaded block 12. The threaded rod 10 connected to the output shaft rotates, which drives the threaded block 12 threadedly sleeved therewith to move, and the threaded block 12 drives the second cleaning plate 18 to move, and the second cleaning plate 18 scrapes back and forth on the surface of the core, increasing the cleaning range of the second cleaning plate 18 for dirt attached to the surface of the core. The cleaned core is manually pushed to the surface of the processing table 22, and the water pump 26 is started. The water in the water tank will be guided along the water pipe to the inside of the multiple nozzles 25, and then continue to spray onto the surface of the core. Spraying water can reduce the contact between the metal surface and the air, reduce the possibility of oxidation, thereby improving the joint strength and weld quality during core welding. Spraying water helps to provide a uniform wet environment for the core surface before welding, and helps to maintain the consistency of the temperature in the welding area. After starting the second servo motor 20, the transmission rod 21 connected to its output shaft is driven to rotate, which also drives the processing table 22 fixedly mounted thereon to rotate. As the processing table 22 tilts, the cleaned core will automatically slide to the surface of the conveying roller 2. After the processing table 22 tilts, the core will slide to the surface of the conveying roller 2 due to inertia. During this process, the core will contact multiple rubber strips 30, and the rubber strips 30 will be deformed when subjected to force. The core is still normally transported to the surface of the conveying roller 2. The set rubber strips 30 can block the sprayed water and avoid large-scale splashing of water. The transmission is realized between multiple conveying rollers 2 through couplings, and the cores are automatically transported one by one to the bottom of multiple welding heads 6, cooperating with the start of the hydraulic cylinder 4 and the micro motor.The position height of the welding head 6 can be adjusted to achieve continuous welding of the car radiator core. The two twisting strips 31 are rotated in the opposite direction to disengage them from the inside of the circular hole, so that the L-shaped plate 29 and the two straight plates 28 can be separated, and a new L-shaped plate 29 can be replaced, so that the L-shaped plate 29 and the rubber strip 30 can be cleaned separately.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
