[0030] like Figures 1 to 7As shown, the utility model is an automatic copper metal welding device, comprising: a workbench 1, a manipulator for loading and unloading materials, a multifunctional device 2 arranged on the workbench 1, a blowing device 3, a welding device 4, and a copper metal clamp 5, wherein the manipulator is arranged on one side of the workbench 1 to facilitate loading and unloading.

[0031] The present invention is provided with two working modes, and its working mode can be changed by the multifunctional device 2, wherein the main function of the first working mode is: clamping or loosening the copper tube by the copper metal clamp 5, so that the copper tube remains stable during welding, which is convenient for welding, and removing dust from the surface of the copper tube by the blowing device 3 to reduce the influence of dust on the welding quality; the main function of the second working mode is: welding the copper tube by the welding device 4, and uniformly heating the copper tube by the blowing device 3 during welding, so that its temperature can be uniformly increased, thereby improving the welding efficiency, and at the same time, uniform heating can avoid local overheating, thereby avoiding deformation and cracking problems during the welding process, and improving the welding quality.

[0032] A heating device for heating the wind is provided inside the workbench 1, a welding groove 11 is provided on the workbench 1, and a gas outlet 1 is provided in the welding groove 11;

[0033] The multifunctional device 2 includes: a protective shell 21 fixedly installed on the workbench 1, a multifunctional component 22, and a connecting rod 23; wherein the multifunctional component 22 is divided according to its function: a rotating clamping component 221 that drives the copper metal clamp 5 to realize the clamping and releasing functions and an air outlet control component 222 that controls the air outlet direction of the blowing device 3.

[0034] The rotating clamping assembly 221 is composed of an active rod 2211, a driven rod 2212, a driving gear 2213 slidably connected to the driven rod 2212, a driven gear 2214 fixedly installed on one end of the driven rod 2212 close to the driving gear 2213, and a motor 2215 that drives the active rod 2211 and the connecting rod 23 to rotate.

[0035] The air outlet control assembly 222 is composed of a connecting member 2222 slidably connected to the driving gear 2213 , a cylinder 2221 driving the connecting member 2222 to move, and a supporting column 2223 with one end fixedly mounted on the connecting member 2222 .

[0036] The active rod 2211 is integrally connected with a convex strip 22111 ; the active gear 2213 is provided with a groove 22113 matching with the convex strip 22111 ; the active gear 2213 is also provided with a slide rail 22112 , and the connecting member 2222 slides along the slide rail 22112 ; the active gear 2213 is matched with the driven gear 2214 .

[0037] The cylinder 2221 is fixedly installed inside the protective shell 21. The cylinder 2221 drives the connecting member 2222 to move, and then the connecting member 2222 drives the driving gear 2213 to slide along the active rod 2211 to control whether the driving gear 2213 is engaged with the driven gear 2214. When the driving gear 2213 is engaged with the driven gear 2214, the device is in the first working mode. When the driving gear 2213 is separated from the driven gear 2214, the device is in the second working mode.

[0038] The motor 2215 is fixedly installed inside the protective shell 21. The motor 2215 is a forward and reverse motor. The driven rod 2212 is a double-headed reverse screw, and the driven rod 2212 is rotatably installed inside the workbench 1. When the equipment is in the first working mode, the active rod 2211 rotates following the motor 2215. The active rod 2211 drives the driven rod 2212 to rotate, thereby driving the copper metal clamp 5 to clamp or release the copper tube. When the equipment is in the second working mode, the active rod 2211 rotates following the motor 2215, but the driven rod 2212 does not rotate following the active rod 2211.

[0039] The copper metal clamp 5 is composed of a clamping base 52 slidably connected to the welding groove 11 and a clamping head 51 for clamping the copper tube. The clamping head 51 is fixedly mounted on the clamping base 52, and the copper tube is sleeved on the clamping head 51. The clamping head 51 clamps the copper tube from the inside to make it more stable and convenient for welding.

[0040] The clamping base 52 is arranged at both ends of the driven rod 2212 and is threadedly connected to the driven rod 2212. When the driven rod 2212 rotates following the active rod 2211, the clamping bases 52 at both ends of the driven rod 2212 move closer to or away from each other along the driven rod 2212, and the clamping base 52 blocks the gas outlet 1 on the welding groove 11. As the clamping base 52 moves, the gas outlet 1 gradually decreases, and the gas outlet 1 is always matched with the copper tube, so that the copper tube can be more comprehensively and evenly contacted with the hot air, and can be evenly heated. At this time, the clamping base 52 will drive the clamping head 51 to move closer to or away from each other, so that the copper tubes at both ends are closer to or away from each other, and then the copper tube can be clamped or loosened from both ends; when the driven rod 2212 does not rotate following the active rod 2211, the positions of the clamping base 52 and the clamping head 51 remain unchanged.

[0041] The blowing device 3 is composed of an air outlet 1 32 opened on the protective shell 21, an air outlet 2 33 opened on the workbench 1, a fan 31 rotating with the connecting rod 23, and an air outlet control panel 35 fixedly installed at the other end of the support column 2223; the air outlet control panel 35 is provided with a vent 351 matching the air outlet 1 32 and the air outlet 2 33.

[0042] A gas outlet 2 is provided on the clamping head 51, and the gas outlet 2 is connected to the inside of the workbench 1; when the equipment is in the first working mode, the vent 351 is connected to the air outlet 1 32, and the wind blown by the fan 31 passes through the air outlet 1 32 to remove dust from the surface of the copper tube, so as to reduce the dust on the surface of the copper tube, ensure the cleanliness of the welding area, and prevent these impurities from entering the weld and affecting the welding quality; when the equipment is in the second working mode, the vent 351 is connected to the air outlet 2 33, and the wind blown by the fan 31 passes through the air outlet 2 33 to enter the inside of the workbench 1, and is converted into hot air by the heating device, and then the hot air flows out from the gas outlet 1 and the gas outlet 2, and the gas outlet 2 is inside the copper tube, which is convenient for uniform heating of the copper tube, and can improve the surface temperature of the copper tube to speed up the welding efficiency. If the copper tube is unevenly heated during the welding process, it will affect the welding quality of the copper tube.

[0043] A pressure sensor is provided on the clamping base 52, and the equipment is also provided with a data processing module for analyzing and processing the data obtained by the pressure sensor, and a PLC controller for controlling the operation of the motor 2215 and the cylinder 2221; the pressure sensor is electrically connected to the data processing module; the PLC controller is electrically connected to the data processing module, the motor 2215 and the cylinder 2221 respectively.

[0044] When the clamping base 52 clamps the copper tube from the inside, the pressure sensor senses the pressure and feeds back data to the data processing module. The data processing module generates a corresponding signal based on the data fed back by the pressure sensor and feeds it back to the PLC controller. Then the PLC controller controls the motor 2215 to stop working and controls the cylinder 2221 to drive the connecting piece 2222 to move, thereby separating the driving gear 2213 from the driven gear 2214, and the equipment enters the second working mode. When the welding is completed, the clamping base 52 releases the copper tube, the pressure sensor does not sense the pressure and feeds back data to the data processing module. The data processing module generates a corresponding signal and feeds back to the PLC controller. Then the PLC controller controls the motor 2215 to stop working and controls the cylinder 2221 to drive the connecting piece 2222 to move, thereby engaging the driving gear 2213 with the driven gear 2214, and the equipment enters the first working mode.

[0045] The utility model discloses an automatic copper metal welding device, which is provided with a first working mode and a second working mode. In the first working mode, the copper tube can be clamped or loosened, and dust can be removed from its surface to prevent the dust on the surface from affecting the welding quality. In the second working mode, the copper tube is welded and uniformly heated at the same time, so that the welding efficiency is high.

[0046] Working principle:

[0047] The manipulator first loads the copper tube. At this time, the equipment is in the first working mode. The copper metal clamp 5 clamps the copper tube. At the same time, the wind blown by the blowing device 3 performs preliminary dust removal on the surface of the copper tube. After clamping, the manipulator moves out and the equipment enters the second working mode. At this time, the welding equipment 4 welds the copper tube. The wind blown by the blowing device 3 evenly heats the surface of the copper tube through the heating device. After welding, the equipment returns to the first working mode again, the copper metal clamp 5 releases the copper tube, and then the manipulator unloads the material.
