Description

The edge-neatening apparatus of silicon crystal photovoltaic module

Technical field

The utility model relates to Crystalline Silicon PV Module finishing field.

Background technology

Crystalline Silicon PV Module is after lamination operation, because EVA melts after being subject to high temperature, the EVA melting during lamination is squeezed, the EVA colloid that the Crystalline Silicon PV Module edge making has shape very irregular produces, but follow-up framing up, the service life that in encapsulation process, these irregular EVA colloids will badly influence the packaging effect of photovoltaic module and have influence on finished product crystal silicon solar assembly, therefore now in manufacturing the process of Crystalline Silicon PV Module, there is a procedure trimming process step, object is exactly to get rid of lamination to produce the irregular colloid exposing, deburring now normally adopts traditional metal material cutter shape structure edge iron to complete the deburring to Crystalline Silicon PV Module.Because present institute employing edge iron has the shortcoming that himself cannot avoid.One, edge iron used does not have heater now, thereby after deburring is completed, at the edge of Crystalline Silicon PV Module, still has trickle burr.Its two, now edge iron used is an integral body, needs integral replacing after damage, has virtually increased production cost.Its three, present edge iron does not have the safety guard of self as a kind of instrument, knife-edge especially easily damages.Its four,, there is personal safety hidden danger to operator and maintenance man in edge iron used now, and this point has no idea to eliminate.

So need now a kind of deburring more accurate, and can not scratch Crystalline Silicon PV Module main body, can reduce operative employee's workload, convenient to operation, cost is low, makes trimmed Crystalline Silicon PV Module the smooth of the edge clean and tidy, and can not scratch operative employee's edge-neatening apparatus.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of edge-neatening apparatus of silicon crystal photovoltaic module, this device deburring is more accurate, and can not scratch silicon crystal photovoltaic module main body, can reduce operative employee's workload, convenient to operation, cost is low, the steel wire of heating makes trimmed Crystalline Silicon PV Module the smooth of the edge clean and tidy, and with electric rotating machine in steel wire cutting process, can make the steel wire carry out rotation, be more conducive to cutting, improved the efficiency of cutting.

For addressing the above problem the technical scheme that the utility model takes, be: this device comprises base, cylinder, U-shaped draw-in groove, steel wire, electric rotating machine, heating module, PLC controller, described U-shaped draw-in groove is horizontally disposed with, and its biside plate is up and down to be arranged, the notch of described U-shaped draw-in groove is towards horizontal direction, in U-shaped draw-in groove, be provided with the steel wire of vertical direction, on epipleural, be provided with electric rotating machine, on lower side panel, be provided with heating module, described steel wire upper end is connected with electric rotating machine through after epipleural, described steel wire lower end is connected with heating module through after lower side panel, described U-shaped draw-in groove is done level and vertical motion by means of cylinder.

Preferred described cylinder is divided into the first cylinder and the second cylinder, the first cylinder and base are fixed, the end of the piston rod of the first cylinder is connected with the second cylinder, the end of the piston rod of the second cylinder is connected with U-shaped draw-in groove, the ejection direction of described the first cylinder upwards, the ejection direction of the second cylinder and the notch of U-shaped draw-in groove towards consistent.

The beneficial effect that adopts technique scheme to produce is: this device deburring is more accurate, and can not scratch Crystalline Silicon PV Module main body, can reduce operative employee's workload, convenient to operation, cost is low, and the steel wire of heating makes trimmed Crystalline Silicon PV Module the smooth of the edge clean and tidy, and with electric rotating machine in steel wire cutting process, can make steel wire carry out rotation, more be conducive to cutting, improved the efficiency of cutting.

Wherein, 1, base, 2, U-shaped draw-in groove, 3, steel wire, 4, electric rotating machine, 5, heating module, 6, epipleural, 7, lower side panel, the 8, first cylinder, the 9, second cylinder.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail: a kind of edge-neatening apparatus of silicon crystal photovoltaic module, it is characterized in that comprising base 1, cylinder, U-shaped draw-in groove 2, steel wire 3, electric rotating machine 4, heating module 5, PLC controller, described U-shaped draw-in groove 2 is horizontally disposed with, and its biside plate is up and down to be arranged, the notch of described U-shaped draw-in groove 2 is towards horizontal direction, in U-shaped draw-in groove 2, be provided with the steel wire 3 of vertical direction, on epipleural 6, be provided with electric rotating machine 4, on lower side panel 7, be provided with heating module 5, described steel wire 3 upper ends are connected with electric rotating machine 4 through epipleural 6 is rear, described steel wire 3 lower ends are connected with heating module 5 through lower side panel 7 is rear, described U-shaped draw-in groove 2 is done level and vertical motion by means of cylinder.

Described cylinder is divided into the first cylinder 8 and the second cylinder 9, the first cylinder 8 is fixing with base 1, the piston rod end of the first cylinder 8 is connected with the second cylinder 9, the piston rod end of the second cylinder 9 is connected with U-shaped draw-in groove 2, the ejection direction of described the first cylinder 8 upwards, the ejection direction of the second cylinder 9 and the notch of U-shaped draw-in groove 2 towards consistent.

Now for former trimming method, the feature of this device is can be enough heated and be that the steel wire 3 of rotation carries out deburring, the mode of simultaneously using with two covering devices, in the middle of the photovoltaic module that needs deburring is placed on, then two assemblings are seated in to the both sides of photovoltaic module, utilize the first cylinder 8 and the second cylinder 9 to carry out the adjusting of position, make the steel wire 3 of both sides near the edge of both sides, then move stably the photovoltaic module that needs deburring, the both sides of photovoltaic module are repaired by steel wire 3.Due to steel wire 3 be rotation be more conducive to deburring.Adopt PLC controller to control, realized automation.

One, with respect to traditional edge iron, steel wire 3 deburrings are more accurate, and can not scratch Crystalline Silicon PV Module main body.We know that traditional edge iron is very heavy, and if install, askewly all can cause damage to Crystalline Silicon PV Module, if and use steel wire 3, we just do not worry this point completely, because installed askew or steel wire 3 has broken and can not have any impact to Crystalline Silicon PV Module main body.

Its two, at the bottom of the cost of hot steel wire edge-neatening apparatus, the consumable accessory of steel wire edge-neatening apparatus is mainly steel wire 3, has damaged and has also been easy to change, and unlike original edge iron, as long as damaged, just must change whole cutter hub.

They are three years old, what we adopted is hot steel wire edge-neatening apparatus, to be EVA colloid burr because of what will remove in Crystalline Silicon PV Module deburring process, and EVA colloid will melt being no more than 100 degree, we are exactly in the process of deburring, to have completed the dissolving of EVA colloid limit by the benefit of steel wire 3 simultaneously like this, thus make that the edge of the Crystalline Silicon PV Module of repairing with steel wire 3 becomes smooth, not crude.
