[0002] The welding strip is an important raw material in the welding process of photovoltaic modules. The quality of the welding strip will directly affect the current collection efficiency of the photovoltaic module and have a great impact on the power of the photovoltaic module. In the production process of the welding strip, the annealing process is a heat treatment process that heats the copper strip to a certain temperature according to the process requirements, keeps it warm for a period of time, and then cools it at an appropriate speed to change the structure and performance of the copper strip; the purpose is to soften the copper strip, improve its plasticity and toughness, make its chemical composition uniform, remove internal residual stress, reduce the yield of the welding strip, increase the welding tension, and extend the service life of the welding strip. However, during the annealing process, due to the high temperature of the copper strip, the surface of the copper strip is easily oxidized into copper oxide, which affects the appearance of the copper strip.

Rotating drum and connecting plate 2, the support plate and connecting plate 1 are fixedly connected by springs, the driving motor is located at the top of connecting plate 1, and the rotating shaft of the driving motor passes through connecting plate 1 and is fixedly connected to the rotating drum, the four corners of the bottom of connecting plate 1 are fixedly installed with fixing rods, the lower end of the fixing rods is fixedly connected to connecting plate 2, a circular through hole is opened on connecting plate 2, a dropper bottle is threadedly connected in the through hole, one end of the dropper bottle close to the rotating drum is sleeved in the rotating drum, a group of mutually extruding blocks are arranged at the connection between the dropper bottle and the rotating drum, and the extrusion blocks are respectively arranged on the outer wall of the dropper bottle and the inner wall of the rotating drum. Through the above technical scheme, alcohol is dripped into the protective air pipe in the form of dripping, and due to the fast falling speed of the dripping, the alcohol does not have time to react and directly drips into the water tank below, resulting in a waste of alcohol; at the same time, the alcohol dripping is intermittent dripping, and the copper oxide treatment on the surface of the welding strip is uneven. Utility Model Content

[0004] The purpose of the utility model is to provide a photovoltaic welding strip annealing and anti-oxidation device, which can continuously spray atomized alcohol to the welding strip through an alcohol pumping mechanism and an alcohol atomizing nozzle, effectively improve the reaction speed of alcohol, effectively reduce the waste of alcohol, and at the same time improve the treatment quality of copper oxide on the surface of the welding strip.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A photovoltaic welding ribbon annealing and anti-oxidation device, comprising a first annealing wheel, a second annealing wheel and an intermediate guide wheel rotatably connected to a frame, the welding ribbon passes through the first annealing wheel, the intermediate guide wheel and the second annealing wheel in sequence; the vertical section of the welding ribbon located between the intermediate guide wheel and the second annealing wheel is inserted into a vertically arranged anti-oxidation tube, and the anti-oxidation tube is fixed to the frame through a bracket;

[0007] A plurality of alcohol atomizing nozzles are fixed on one side wall of the anti-oxidation tube, and the alcohol atomizing nozzles are arranged directly opposite to the vertical section;

[0008] A plurality of alcohol atomizing nozzles are connected with an alcohol pumping mechanism.

[0009] Through the above technical solution, the first annealing wheel and the second annealing wheel are energized, so that a section of the welding strip between the first annealing wheel and the second annealing wheel is short-circuited, thereby heating it, and the vertical section is also in a high temperature state. The upper end of the vertical section is exposed to the air and is easily oxidized, thereby generating copper oxide on the surface of the vertical section;

[0010] The alcohol pump mechanism presses the alcohol toward the alcohol atomizing nozzle, and the alcohol atomizing nozzle sprays the atomized alcohol toward the vertical section. Since the temperature of the vertical section is relatively high, the atomized alcohol reduces the copper oxide and reduces it to copper. The chemical reaction formula is: CH3CH2OH + CuO ==△== Cu + CH3CHO + H2O. Since the alcohol is atomized, the reaction area can be increased and the reaction speed can be accelerated. At the same time, alcohol can generate hydrogen and carbon monoxide under heating conditions. The chemical reaction formula is: CH3CH2OH + H2O==△==4H2+ 2CO. Hydrogen and carbon monoxide have strong reducing properties, so the copper oxide on the copper strip can be completely reduced.

[0011] The utility model is further configured as follows: the alcohol atomizing nozzle comprises a nozzle head inserted on a side wall of the anti-oxidation tube, a locking portion and a connecting tube;

[0012] The outer end of the spray head is formed with a cone and an outer wall thread; the interior of the spray head is formed with a connecting hole, a cone hole, a fine hole and an arc hole in sequence from the outside to the inside; the outer end of the connecting hole is formed with a plurality of slots that are evenly distributed around the circumference and penetrate the cone;

[0013] The inner end of the connecting pipe is inserted into the connecting hole, and the outer ends of the connecting pipes of the multiple alcohol atomizing nozzles are connected to the high-pressure liquid supply pipe of the alcohol pumping mechanism;

[0014] The locking portion is formed with a tapered hole and an inner wall thread arranged from the outside to the inside, the tapered hole is pressed against the outer wall of the tapered portion, and the inner wall thread is screwed onto the outer wall thread.

[0015] Through the above technical solution, the installation steps of the alcohol atomizing nozzle are as follows: the nozzle head is inserted into the side wall of the anti-oxidation tube from the inside to the outside, and then the locking part is inserted into the connecting tube, the connecting tube is inserted into the connecting hole, and the locking screw is connected to the outer wall thread. The inner wall of the tapered hole squeezes the cone inward, and the cone clamps the connecting tube, thereby completing the fastening of the alcohol atomizing nozzle;

[0016] The high-pressure alcohol in the high-pressure liquid supply pipe is divided and flows to multiple alcohol atomizing nozzles. Since the diameter of the fine holes is small, the flow rate and pressure of the alcohol are increased. After the alcohol flows to the arc hole, it forms a mist and sprays toward the welding strip.

[0017] The utility model is further configured that a rubber ring is clamped between the inner end of the locking portion and the outer wall of the anti-oxidation tube.

[0018] Through the above technical solution, the resistance between the locking part and the anti-oxidation tube can be increased by the rubber ring to prevent the locking part from loosening.

[0019] The utility model is further configured as follows: the alcohol pump pressure mechanism also includes a pump body fixed on the frame, the pump body is formed with cylinder holes symmetrically arranged up and down and a rectangular guide hole connecting the two cylinder holes, each cylinder hole is sleeved with a piston, the two pistons are symmetrically arranged and respectively fixed at the two ends of the push-pull part, the middle part of the push-pull part is formed with a rectangular slider matched with the rectangular guide hole, the middle part of the rectangular slider is formed with a waist-shaped hole, the waist-shaped hole is inserted on the driving shaft, the driving shaft is fixed to one end of the driving arm, the other end of the driving arm is fixedly connected with a large gear through a connecting shaft, the large gear is meshed with a small gear, the small gear is fixed on the motor shaft of the motor, and the motor is fixed on the pump body;

[0020] A cylinder cover is fixed on the end face of each cylinder hole, and a liquid inlet hole and a liquid outlet hole are formed on the cylinder cover. The liquid inlet hole is connected to a liquid inlet branch pipe, and the liquid outlet hole is connected to a liquid outlet branch pipe; the other ends of the two liquid inlet branch pipes are inserted and sleeved on the liquid inlet valve, the liquid inlet valve is connected to a liquid inlet main pipe, and the liquid inlet main pipe is connected to the alcohol storage barrel; the other ends of the two liquid outlet branch pipes are inserted and sleeved on the liquid outlet valve, the liquid outlet valve is connected to a liquid outlet main pipe, and the liquid outlet main pipe is connected to a high-pressure liquid supply pipe.

[0021] The liquid inlet valve has two symmetrically arranged liquid inlet one-way valve holes formed therein, and a first steel ball and a first compression spring are sleeved in the liquid inlet one-way valve holes;

[0022] The liquid outlet valve is formed with two symmetrically arranged liquid outlet one-way valve holes, each of which is sleeved with a second steel ball, and a second compression spring is sandwiched between the two second steel balls.

[0023] Through the above technical solution, the rotation of the motor drives the small gear to rotate, the small gear drives the large gear to rotate, the large gear drives the driving arm to rotate through the connecting shaft, the driving arm drives the rectangular slider to move back and forth through the driving shaft and the waist-shaped hole, and the rectangular slider drives the two pistons to move back and forth. When the piston is away from the cylinder head, the pressure in the cylinder hole becomes low, and the alcohol flowing from the alcohol storage barrel into the liquid inlet valve through the liquid inlet main pipe is sucked into the cylinder hole by the liquid inlet branch pipe; then when the piston moves toward the cylinder head, the piston squeezes the alcohol in the cylinder hole toward the liquid outlet valve through the liquid outlet branch pipe, and then enters the high-pressure liquid supply pipe through the liquid outlet main pipe.

[0024] The utility model is further configured as follows: the alcohol storage barrel is placed in a light-proof shell.

[0025] The above technical solution can reduce the volatilization of alcohol.

[0026] The outstanding effects of the utility model are:

[0027] Compared with the prior art, the alcohol pump mechanism and the alcohol atomizing nozzle can continuously spray atomized alcohol to the solder strip, which can effectively increase the reaction speed of the alcohol, effectively reduce the waste of alcohol, and at the same time improve the processing quality of copper oxide on the surface of the solder strip.

[0051] The alcohol pump mechanism presses the alcohol toward the alcohol atomizing nozzle, and the alcohol atomizing nozzle sprays the atomized alcohol toward the vertical section. Since the temperature of the vertical section is relatively high, the atomized alcohol reduces the copper oxide and reduces it to copper.
