Description

Technical Field

[0001] This utility model relates to the field of copper wire processing technology, and more specifically, to an annealing and anti-oxidation device for copper wire used in new energy photovoltaics. Background Technology

[0002] In the new energy photovoltaic industry, copper wire is an important conductive material, and its performance plays a key role in the efficiency and stability of photovoltaic systems. Annealing is an important process to improve the performance of copper wire. However, during the annealing process, copper wire is very prone to oxidation reaction with oxygen in the air, which affects its conductivity and service life.

[0003] Utility model patent application number CN201921468208.0 discloses a copper wire annealing device for preventing copper wire oxidation. The device includes an annealing unit and an anti-oxidation unit. A copper wire is movably connected to the inner cavity of the annealing unit. The other end of the copper wire penetrates the outer wall of the annealing unit and extends to the outside of the unit, where it is movably connected to a first drive wheel. The copper wire and the outer wall of the first drive wheel are movably connected. A top plate is fixedly installed on the top of the first drive wheel. This utility model utilizes a liquid zinc storage tank and a grinding device. The device can plate the surface of the copper wire, allowing the liquid zinc to solidify and form a protective layer on its surface. The grinding discs inside the grinding device then polish the zinc plating layer on the copper wire surface, maintaining its gloss and smoothness. This device effectively protects the copper wire, thus effectively preventing oxidation of the copper wire surface, preventing short circuits caused by copper wire oxidation, and preventing increased power consumption.

[0004] When the copper wire is wound in the aforementioned patent, due to the lack of this lateral traction mechanism, the copper wire tends to spontaneously wrap around the end that initially contacts the winding roller under the action of the rotational force of the winding roller. This prevents the copper wire from being evenly wound on the winding roller. During the continuous winding process, the copper wires are prone to squeezing and intertwining with each other, resulting in a chaotic winding situation.

[0005] Therefore, we have made improvements to this and proposed an annealing and anti-oxidation device for copper wire used in new energy photovoltaics. Utility Model Content

[0006] The purpose of this invention is to address the problem that when winding copper wire, due to the lack of a lateral traction mechanism, the copper wire tends to spontaneously wrap around the initial contact end of the winding roller under the action of the rotational force of the winding roller, which prevents the copper wire from being evenly wound on the winding roller. During the continuous winding process, the copper wires are prone to squeezing and intersecting with each other, resulting in a chaotic winding situation.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] An annealing and anti-oxidation device for copper wire used in new energy photovoltaics is proposed to improve the above-mentioned problems.

[0009] The application is as follows:

[0010] The furnace includes: an annealing furnace body mounted on a base plate; a housing mounted on the base plate, the housing containing a liquid zinc storage tank; fixed plates mounted on both sides above the base plate, with a winding roller rotatably fitted between the two fixed plates; a stepper motor mounted on the outer side of each fixed plate, the output shaft of which passes through the fixed plate and is mounted at the central axis of the winding roller; the annealing furnace body, the housing, and the two fixed plates are arranged sequentially from left to right; and a winding assembly is provided between the two fixed plates and the winding roller.

[0011] To achieve the above technical solution, the rotation of the take-up roller drives the first screw to rotate, which in turn causes the L-shaped frame to move laterally, driving the fixed guide wheel and the moving guide wheel to move laterally. This achieves lateral traction of the copper wire on the take-up roller, avoiding the situation where the copper wire tends to wrap around the initial contact end only under the rotational force of the winding roller. It enables the copper wire to be wound evenly on the take-up roller, reducing the situation of mutual squeezing, crossing, and messy winding of the copper wire during continuous winding, and improving the quality of copper wire winding.

[0012] As a preferred embodiment of the copper wire annealing and anti-oxidation device for new energy photovoltaic provided by this utility model, the outer walls of the box body facing the annealing furnace body and the fixing plate are equipped with first transmission wheels, and the outer walls of the box body facing the annealing furnace body and the fixing plate are provided with material inlets that communicate with the interior.

[0013] As a preferred embodiment of the copper wire annealing and anti-oxidation device for new energy photovoltaics provided by this utility model, second drive wheels are installed on both inner walls and the bottom of the box, and the second drive wheels on both inner walls of the box are located below the material inlet.

[0014] To achieve the above technical solution, the copper wire to be processed starts from the annealing furnace body, and after annealing, it enters the furnace body through the material port on the furnace body. Inside the furnace body, it undergoes anti-oxidation treatment in a liquid zinc storage tank, and then exits from the material port on the other side, finally reaching the winding assembly and take-up roller for winding.

[0015] As a preferred embodiment of the copper wire annealing and anti-oxidation device for new energy photovoltaic provided by this utility model, the winding assembly includes an L-shaped frame disposed between two fixed plates, and a fixed guide wheel and a moving guide wheel are respectively rotatably fitted on the upper and lower sides of the L-shaped frame.

[0016] As a preferred embodiment of the copper wire annealing and anti-oxidation device for new energy photovoltaic provided by this utility model, a first screw is rotatably fitted between the two fixing plates, and a threaded cylinder that is threadedly fitted with the first screw is installed on one side of the L-shaped frame.

[0017] In a preferred embodiment of the copper wire annealing and anti-oxidation device for new energy photovoltaics provided by this utility model, a first synchronous wheel is installed at one end of the first screw, a second synchronous wheel is installed on one side of the central shaft of the take-up roller, and a synchronous belt is sleeved between the first synchronous wheel and the second synchronous wheel.

[0018] As a preferred embodiment of the copper wire annealing and anti-oxidation device for new energy photovoltaic provided by this utility model, a fixing rod is installed between the fixing plates on both sides, and a sliding cylinder that is slidably fitted on the fixing rod is installed on one side of the L-shaped frame.

[0019] As a preferred embodiment of the copper wire annealing and anti-oxidation device for new energy photovoltaic provided by this utility model, displacement blocks are rotatably fitted on both sides of the moving guide wheel, displacement grooves that slide with the displacement blocks are opened on both sides of the L-shaped frame, a second screw is rotatably fitted at the bottom of the displacement block, and a threaded groove that threads with the second screw is opened on the bottom wall of the displacement groove.

[0020] To achieve the above technical solution, the first screw is rotated by the rotation of the take-up roller, which in turn causes the L-shaped frame to move laterally, thereby driving the fixed guide wheel and the moving guide wheel to move laterally, thus realizing the lateral traction of the copper wire on the take-up roller.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This utility model provides an annealing and anti-oxidation device for copper wire used in new energy photovoltaics, comprising: an annealing furnace body mounted on a base plate; a box mounted on the base plate, the box containing a liquid zinc storage tank; fixed plates mounted on both sides above the base plate, with a winding roller rotatably coupled between the two fixed plates; a stepper motor mounted on the outer side of each fixed plate, the output shaft of which passes through the fixed plate and is mounted at the central axis of the winding roller; the annealing furnace body, the box, and the two fixed plates are arranged sequentially from left to right; a winding assembly is provided between the two fixed plates and the winding roller. The rotation of the winding roller drives the first screw to rotate, thereby causing the L-shaped frame to move laterally, which in turn drives the fixed guide wheel and the moving guide wheel to move laterally, achieving lateral traction of the copper wire on the winding roller. This avoids the situation where the copper wire tends to wind around only one end under the rotational force of the winding roller, allowing the copper wire to be evenly wound on the winding roller, reducing the situation of mutual squeezing, interlacing, and chaotic winding of the copper wire during continuous winding, and improving the quality of copper wire winding.
