Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic wire preparation, and in particular to a new energy photovoltaic wire preparation process and device. Background Art

[0002] Under the current premise of vigorous development of new energy, photovoltaic cables have become an industry strongly supported by the country, and the demand for photovoltaic cables in the new energy industry has gradually increased.

[0003] In the traditional photovoltaic wire manufacturing process, the thicker copper wire needs to be drawn and annealed by the wire drawing annealing machine first, then reeled and transferred to a factory with a tinning machine for tinning. After tinning, the photovoltaic wire is reeled and packaged into a finished product. After tinning, the wire reeling part is also manually changed. The labor, transportation, inventory and time loss costs are countless, which is time-consuming and labor-intensive, greatly reducing the production efficiency of photovoltaic wires and increasing production costs. Summary of the invention

[0004] The purpose of the present invention is to provide a new energy photovoltaic line preparation process and device in order to overcome the defects of the above-mentioned prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A new energy photovoltaic line preparation process, the preparation process comprising the following steps:

[0007] 1) Prepare the copper wire coils needed to manufacture photovoltaic wires, roll them on the wire drum, and insert the copper wire into the wire drawing machine feed frame. The operator starts the equipment slowly by manual operation. The copper wire is wound separately on the four tower wheels of the wire drawing machine along with the inlet die on the equipment. During the operation of the wire drawing machine, the mechanical pulling force will make the copper wire thinner according to the set value in turn;

[0008] 2) After the wire drawing machine has finished drawing the copper wire, the copper wire passes through the outlet die of the wire drawing machine, and is connected to the inlet wheel of the next station annealing machine through the outlet frame after being adjusted by the tension swing rod, and then is wound from the inlet wheel into the heating copper wheel, and after being heated by the heating copper wheel, it enters the cooling water tank for cooling and annealing to increase the hardness of the copper wire;

[0009] 3) Repeat the process of steps 1) and 2) with another wire drawing machine and annealing machine;

[0010] 4) After annealing, the copper wire passes through the pickling tank of the tinning machine to brush off the surface impurities and then enters the tin furnace. After tinning in the tinning furnace, the copper wire passes through the air duct of the tinning machine to quickly cool the tin on the surface of the copper wire;

[0011] 5) After tinning, the copper wire passes through the wire wheel and reaches the wire take-up machine. The copper wire begins to be wound on the rubber barrel of the first take-up shaft of the wire take-up machine. When the copper wire is wound, it automatically switches when the number of meters set by the program reaches the specified value, and starts to continue to be wound on the second take-up shaft;

[0012] 6) When the first take-up shaft completes winding the rubber barrel, it will transmit a signal to the automatic reel-changing mechanism below. The automatic reel-changing mechanism will move to the bottom of the rubber barrel, the clamping mechanism of the rubber barrel will release, and the rubber barrel will fall onto the tray of the automatic reel-changing mechanism. The automatic reel-changing mechanism will move to the unloading position of the conveyor;

[0013] 7) When the automatic reel-changing mechanism reaches the unloading position of the conveyor, it dumps the wound rubber barrel onto the conveyor belt. The conveyor belt moves forward to send the rubber barrel to the rear for workers to pick up the parts. At the same time, the automatic reel-changing mechanism rises to the empty barrel picking position. The upper block rises to slide the empty rubber barrel onto the tray of the automatic reel-changing mechanism. The automatic reel-changing mechanism then returns to the rubber barrel placement position of the first take-up shaft. The first take-up shaft clamps the rubber barrel, and the whole barrel collection and changing process is completed.

[0014] 8) The remaining take-up reels reciprocate according to the process of step 7). The operator only needs to take away the finished photovoltaic wire glue barrels and send them to the warehouse and then fill the empty barrels at the empty barrel picking position.
