Description
Technical Field
The utility model relates to a solar cell photovoltaic stringer's part specifically indicates a photovoltaic stringer pulls to weld takes with pressing from both sides tight gasket and pulls clamping jaw.
Background
A traction clamping jaw for a traction welding strip of a photovoltaic series welding machine is an important part on a solar cell production line and is used for clamping the welding strip of a cell.
The structure of a traction clamping jaw for a traction welding belt of a conventional photovoltaic series welding machine is shown in fig. 1, wherein the clamping jaw is provided with a jaw body, a containing groove 2 is formed in the jaw body, and a gasket is embedded in the containing groove 2. As shown in fig. 2 and 3, the gasket is a fillet gasket 3, the gasket is generally made of PEEK (polyether ether ketone) or stainless steel, two edge corners of the upper surface of the gasket contacting with the welding strip are fillets, the radius of each fillet is 0.2mm, the thickness of the gasket is 2.0mm, the depth of the groove of the accommodating groove 2 is 1.9mm, and the upper surface of the gasket is higher than the upper surface of the claw body after installation. When in use, the welding strip is clamped by the gasket.
The existing gasket is made of easily-consumed PEEK or stainless steel, so that the upper surface of the gasket is higher than the upper surface of the claw body after installation, the service life of the gasket is prolonged, and if the gasket is installed, pits are easily formed when the gasket is used, and a welding strip cannot be stably clamped. In order to avoid the pad from scraping the welding strip, the pad needs to be provided with transition fillets at two edge corners of the upper surface in contact with the welding strip.
The gasket of the existing traction clamping jaw has the following defects:
(1) the thickness of the existing gasket is larger than the groove depth of the containing groove, and the gasket is higher than planes on two sides of the groove after assembly, so that the head of the welding strip is easily bent and deformed when the welding strip is clamped and conveyed, the head of the welding strip can be damaged, and the pulled welding strip cannot achieve a straight effect.
(2) Two edge corners of the upper surface of the existing gasket, which is contacted with the welding strip, are rounded corners, so that the gasket can be used only on a single surface and cannot be used on two surfaces. When the working surface used has worn a certain amount, it is necessary to replace the shim with a new one, resulting in a waste of material.
(3) When the gasket is got to the clamp and is got the solder strip, because the solder strip body has certain thickness, can produce great reaction force to the surface of gasket. Because the material of current gasket is PEEK or stainless steel, this material surface is wear-resisting, leads to the gasket surface to appear after long-time fortune is done like the recess 31 of rectangular shape shown in fig. 3, and the gasket can consequently recess 31 cause to weld the area and can't normally put to the battery piece when pressing from both sides when getting and welding the area, leads to the clamping jaw area to weld the area, increases the fault rate and influences the output, increases cost loss, and life cycle is short-lived. This anomaly is common in the industry in series welder equipment and has not been effectively addressed.
SUMMERY OF THE UTILITY MODEL
One of the purposes of the utility model is to provide a photovoltaic series welding machine draws and welds area and use tight gasket of clamp, and this gasket can make the solder strip of pulling out reach straight effect.
The utility model discloses a this purpose is realized through following technical scheme: the utility model provides a photovoltaic series welder pulls and welds area and uses clamping pad which characterized in that: the thickness of the gasket is the same as the depth of a containing groove which is formed in the traction clamping jaw of the photovoltaic series welding machine and used for embedding the gasket.
The utility model discloses a gasket thickness is the same with the groove depth of storage tank, and the upper surface of assembly back gasket is parallel and level mutually with the upper surface of the claw body, is difficult for the welding strip head formation deformation of bending when pressing from both sides to send the welding strip like this, and the welding strip head that can not harm for the welding strip of pulling out reaches straight effect.
In the utility model discloses, the thickness of gasket is 1.9 mm.
The utility model discloses can do as follows the improvement: the gasket is a rectangular gasket, and two edge corners of the upper surface of the gasket, which is in contact with the welding strip, are right angles.
The utility model discloses a gasket sets up to the rectangle, improves the convenience of installation and the stability after the gasket installation. Meanwhile, the rectangular structure enables the two sides of the gasket to be utilized, when one side of the gasket is abraded to a certain amount, the gasket can be turned over, and the other side of the gasket is used as a working surface to be used continuously, so that materials are saved, and the service life of the gasket is prolonged.
In a preferred embodiment, the gasket is made of ceramic.
The utility model discloses a gasket adopts hard wear-resisting ceramic material, and the gasket surface can not produce great effort to its surface because of the thickness that welds the area body when pressing from both sides to get and welds the area, leads to the surface to appear the recess after long-time fortune is done, finally appears pressing from both sides to get the back and welds the area card and in the recess, arouse the clamping jaw area and weld the phenomenon of taking and take place.
The gasket is wear-resistant, easy to clean and long in service life, can solve the problem that the welding strip cannot be normally placed on a battery piece and is led to the welding strip due to the fact that the groove is formed when the welding strip is clamped at present, and is suitable for being widely popularized and applied in the industry.
The second purpose of the utility model is to provide a photovoltaic series welding machine pulls to weld takes with pulling clamping jaw, and this clamping jaw can effectively avoid taking to weld and take.
The utility model discloses a this purpose is realized through following technical scheme: photovoltaic series welding machine that contains above-mentioned clamping shim draws welding tape with drawing clamping jaw, its characterized in that: the clamping jaw is provided with a jaw body, the jaw body is provided with a containing groove, the gasket is embedded in the containing groove, and the upper surface of the gasket is flush with the upper surface of the jaw body.
Compared with the prior art, the utility model discloses a clamping jaw and gasket can effective control because the phenomenon in clamping jaw area solder strip that wearing and tearing lead to takes place, improve the life of gasket, reduce the fault rate, reduce unnecessary and shut down the maintenance, practice thrift the cost, easily clearance.
