Description
Technical field
The present invention relates to a kind of instrument that degree of crosslinking detects that is used for, be meant that specifically being used for degree of crosslinking detects the device of sample strip being peeled off into EVA bar and backboard bar.
Background technology
Degree of crosslinking is claimed crosslinking index again; Be used to characterize the crosslinking degree of macromolecular chain; Usually represent with the number-average molecular weight between cross-linking density or two the adjacent crosslinking points or the molal quantity of every cubic centimetre of crosslinking points, can record degree of crosslinking than method with mechanics method or equilibrium swelling; The caoutchouc elasticity that degree of crosslinking is little is better, and the caoutchouc elasticity that degree of crosslinking is big is poor, and degree of crosslinking increases again, and physical strength and hardness all will increase, and finally follow the string.Along with the continuous development of photovoltaic new energy field, various support equipments are also in constantly innovation and renewal in the industry.And in Crystalline Silicon PV Module is produced the detection components degree of crosslinking step that is absolutely necessary; Assembly production is to be based upon on the qualified basis of assembly degree of crosslinking to carry out, so guarantee that in industry the accuracy of degree of crosslinking experiment is very important.But even to this day, on degree of crosslinking sample sampling link, also there is not its pairing sampling equipment to satisfy requirement of experiment.
At current line in the industry, the method for producing the degree of crosslinking sample generally is to adopt artificial preparation method: at first, use small size tempered glass to make experiment package training sheet; Then, treat that the compacting of experiment training sheet is accomplished after, on training sheet chosen position, use cutter to draw the zone of getting 10mm * 30mm by manual work, use tweezers that EVA is separated with backboard; At last, be the granule of 2mm * 2mm with the EVA that takes off through artificial clip, guarantee that the size of particle meets size expense tool to the EVA particle sizing, choose satisfactory EVA particle.
Above method still exists some shortcomings and difficult point: 1 draws the sample strip of getting on experiment training sheet generally is to use tonger under drawing on glass; Sample strip is the adherend of EVA and backboard, and simultaneously EVA and glass also are coherent, and need EVA and glass be separated is need very big strength at present; General no matter be the combination of which kind of material; The peel strength of glass and EVA all slightly is better than the peel strength of backboard and EVA, and the value of these two kinds of peel strengths is between 150N/10mm-200 N/10mm, and EVA can produce deformation when choosing sample strip; EVA and backboard have a tangible range difference; This time, deformation took place in EVA, and this part the deformation EVA that gets off of choosing is drawn thinly on the basis of original thickness, and deformation EVA can not be used for the degree of crosslinking experiment; That is: operating personnel's effort in the sampling process uses cutter and tonger dangerous; Sample strip after the sampling can not be utilized fully; The laboratory sample EVA that stands after the mechanical stress effect possibly influence experimental result.After 2 EVA laboratory sample bars took off, when making the EVA particle, the method for artificial preparation was under the situation of personnel's range estimation, to use scissor cut to go out the laboratory sample particle of particle size at 2 ± 0.5mm * 2 ± 0.5mm; But particle size is wayward, if it is big to use measurer to measure the screening workload, and the waste experiment material, cause man power and material's waste.
Summary of the invention
The objective of the invention is to overcome and be difficult to the problem that the EVA plate with sample strip separates with the backboard bar in the problems referred to above; Provide a kind of degree of crosslinking that is used for to detect the device of sample strip being peeled off into EVA bar and backboard bar; The EVA plate of sample strip is separated with the backboard bar, reach the purpose of one operation.
The object of the invention is realized through following technical proposals:
Be used for degree of crosslinking and detect the device of sample strip being peeled off into EVA bar and backboard bar; Comprise substrate; Substrate is provided with backboard bar hoe scaler, in the blade side of backboard bar hoe scaler backboard bar spool is installed, and at the opposite side of substrate the driving mechanism that is connected with backboard bar spool is installed.Substrate is in vertical state usually, also can be free position, is provided with a backboard bar hoe scaler above that; The blade of backboard bar hoe scaler is made up of a plane and an inclined-plane, and the blade of backboard bar hoe scaler is perpendicular to the plate face of substrate, and one side is equipped with backboard bar spool on the plane of blade; This backboard bar spool is driven by the driving mechanism of substrate opposite side; Under the drive of driving mechanism, backboard bar spool rotates and the backboard bar is rolled into whole circle, and driving mechanism can be manual transmission; Also can be drive of motor, decide according to actual conditions; During use, the start-up portion separation with sample strip becomes EVA plate and backboard bar; The backboard bar is wrapped on the backboard bar spool spool, simultaneously, the EVA plate is connected to shear after through guide pulley; The blade of backboard bar hoe scaler is between EVA plate and backboard bar, and under the drive of backboard bar spool and shear, the relative backboard bar of sample strip hoe scaler moves; Blade separates the EVA plate with the backboard bar, accomplish stripping operation.
On the substrate of said backboard bar hoe scaler both sides, be provided with a guide pulley respectively at least.Further say, in order to control the angle angle between EVA plate, backboard bar and the blade, through guide pulley is set; Not only can retentive control EVA plate, the position relation between backboard bar and the blade; And can keep the tension force of EVA plate and backboard bar, help using in large quantity good stability.
Described backboard bar spool is made up of two semicylinders that keep at a certain distance away, and perhaps backboard bar spool integral body is cylindric, and its surface offers the breach that extends along axis.Say that further the effect of backboard bar spool is that the backboard bar is fixed thereon, be convenient to the backboard bar and be rolled into whole volume; Therefore; Backboard bar spool usually adopts two kinds of structures: two structures that semicylinder keeps at a certain distance away, or integral body is cylindric, offers breach above that; Breach extends vertically, also can adopt other common structure.
On said backboard bar spool, transparent protective cover is installed.Further say, as further improvement of the present invention, for the ease of collecting the backboard bar; Avoid the backboard bar to be scattered, on backboard bar spool, be covered with transparent protective cover, have import on the protective cover; The backboard bar gets in the protective cover from import; After rolling completion, protective cover is taken off, the backboard bar is taken away promptly reusable.
