Abstract
The utility model discloses a kind of string welding machine welding stage pressing structure, it includes pedestal, the multiple pressings being connected on pedestal, pressing includes body, the syringe needle in cylinder being connected with pedestal, syringe needle is located at the opposite other end in the one end that is connected with pedestal of body, and the cross-sectional diameter of syringe needle is more than the cross-sectional diameter of body.The utility model string welding machine welding stage pressing structure, by changing string welding machine welding stage pressing, cylinder is changed to by original conical syringe needle, reduce because pressing contact area is small and caused by cell piece fragmentation and fine fisssure defective products produce, improve welding quality.
Description
Technical field
It the utility model is related to a kind of string welding machine welding stage pressing structure.
Background technology
The welding of solar battery sheet is the highly important technique together during photovoltaic module is manufactured.With photovoltaic system
The automated production for making industry is gradually popularized, and production scale gradually expands, and low production efficiency, the human cost of manual welding are high,
Through the requirement that can not meet large-scale production.Photovoltaic module manufacturing enterprise generally all realizes welding using full-automatic string welding machine at present
Technique.Solar battery sheet is mostly using induction brazing, infrared bonding, electromagnetic field of high frequency weldering, hot-air weldering or miniature gas brazing
Interconnected etc. welding method welding welding.The upper and lower surface of solar battery sheet is respectively cathode and anode, and welding is usually
Copper strips, is enclosed with scolding tin outside copper strips.By taking infrared bonding as an example, one side of welding is laid on the previous piece of sun in process
The upper front of energy cell piece, and expose the another side of welding, latter piece of solar battery sheet is then placed on previous piece
Adjacent position and the top for being pressed in welding another side, then pass sequentially through these end to end multiple solar battery sheets red
Outer soldering tip, melts the scolding tin on welding at a high temperature of infrared ray, completes the welding of welding and solar battery sheet and makes too
Positive energy cell piece is serially connected together.
On the market by largely with welding be face bonding band, welding when by using welding stage pressing can butt welding bring into
The preferable positioning of row.The syringe needle of routine string welding machine welding stage pressing is cone at present, and as shown in Figure 1, the type pressing is most
End cross-sectional area is smaller, and weld job carries out heating welding with point contact, and pressing contact area is smaller, easily damages battery by pressure
Piece, caused cell piece fine fisssure, produces fragmentation defective products.
Utility model content
In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of string welding machine welding stage pressing knot
Structure.
In order to achieve the above object, the utility model provides a kind of string welding machine welding stage pressing structure, it includes pedestal, connects
The multiple pressings being connected on pedestal, pressing include body, the syringe needle in cylinder being connected with pedestal, and syringe needle is located at body
Be connected the opposite other end in one end with pedestal, and the cross-sectional diameter of syringe needle is more than the cross-sectional diameter of body.
Further, body is cylinder.
Further, the axial length of body is more than the axial length of syringe needle.
Further, multiple pressings, which are formed, is parallel to each other and evenly distributed several columns.
Further, in several columns, the pressing spacing in each row is identical.
Further, pedestal is provided with the matrix of several strips, and several columns are arranged on matrix correspondingly.
Further, pressing is ceramic material.
By adopting the above-described technical solution, the utility model string welding machine welding stage pressing structure, is welded by changing string welding machine
Platform pressing, cylinder is changed to by original conical syringe needle, reduce because pressing contact area is small and caused by cell piece break
Piece and fine fisssure defective products produce, and improve welding quality.
Brief description of the drawings
Attached drawing 1 is the structure diagram of the string welding machine welding stage pressing structure in background technology；
Attached drawing 2 is the structure diagram of the string welding machine welding stage pressing structure of the utility model.
Figure label is：
1st, pedestal；11st, matrix；2nd, pressing；21st, body；22nd, syringe needle.
Embodiment
The preferred embodiment to the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature.
Referring to attached drawing 2, the string welding machine welding stage pressing structure in the present embodiment, it includes pedestal 1, is connected on pedestal 1
Multiple pressings 2.
Pressing 2 includes body 21, the syringe needle 22 in cylinder being connected with pedestal 1.Syringe needle 22 be located at body 21 with
Pedestal 1 is connected the opposite other end in one end.
Body 21 is also cylinder.The cross-sectional diameter of syringe needle 22 is more than the cross-sectional diameter of body 21.The axis of body 21
It is more than the axial length of syringe needle 22 to length
In a kind of highly preferred embodiment, multiple formation of pressings 2 are parallel to each other and evenly distributed several columns.If
In dry row, 2 spacing of pressing in each row is identical.In the present embodiment as shown in Figure 2, pedestal 1 is provided with several strips
The matrix 11 of shape, above-mentioned several columns pressing 2, each row are all arranged on matrix 11 correspondingly.
In a kind of highly preferred embodiment, pressing 2 is ceramic material.
This string welding machine welding stage pressing structure, by changing string welding machine welding stage pressing 2, original conical syringe needle 22 is changed
For cylinder, reduce because pressing contact area is small and caused by cell piece fragmentation and fine fisssure defective products produce, improve welding
Quality.
The utility model is elaborated above in association with embodiment, is only the technical concept for illustrating the utility model
And feature, can not be with this its object is to allow person skilled in the art to understand the content of the utility model and be carried out
The scope of protection of the utility model is limited, all equivalent change or modifications done according to the utility model Spirit Essence, should all contain
Cover within the protection scope of the present utility model.
