Description

The laminating machine of loam cake rising and smooth decreasing

Technical field

The present invention relates to the equipment in a kind of solar module production technology, relate in particular to a kind of even zone of heating press of hot plate that is applicable to solar cell assembling technology.

Background technology

Be accompanied by the continuous progress of rapid economy development and science and technology, social life also sharply increases for the consumption and the demand of the energy.At present human widely used energy major part is still for being the fossil class energy of representative with coal, oil.Fossil class energy development so far, though its exploitation operation technique is very ripe, the problem of association can not be ignored too thereupon.At first, the fossil class energy is non-renewable resources, and it stores total amount must be an irreversible procedure that constantly reduces; Secondly, the fossil class energy in use can produce a large amount of pollutions, and the carbon dioxide that produces in the coal oil combustion process, sulfur dioxide and nitrilo compound can cause greenhouse effects and serious pollution.Therefore, people's suitable attention and development that the demand of new forms of energy and exploitation are got in the last few years.

In the new forms of energy research that has practical value at present, the collection of solar energy and utilization belong to relatively ripe and have the technology of practical value.Its basic principle is that solar irradiation is on the semiconductor p-n junction, form new hole-duplet, under the p-n junction effect of electric field, the hole flows to the p district by the n district, electronics flows to the n district by the p district, just form electric current after connecting circuit, solar radiant energy is directly changed into electric energy, the basic device of light-electricity conversion is exactly a solar cell.Solar cell is a kind of device that solar energy is converted into electric energy owing to photovoltaic effect, it is a semiconductor photo diode, when solar irradiation was to photodiode, photodiode will become electric energy to the luminous energy of the sun, produced electric current.When being together in series or parallel, many batteries just can become solar cell array that bigger power output is arranged.Solar cell has chronicity, spatter property and flexibility three big advantages. and solar battery life is long, as long as the sun exists, solar cell just can once be invested and long-term the use; Compare with thermal power generation, nuclear energy power generation, solar cell can not cause environmental pollution; Solar cell can large, medium and smallly develop simultaneously, and arrives the medium-sized power station of gigawatt greatly, and little compound mode is flexible to the solar battery group of only using for a family, and this is that other power supply is incomparable.

In the production of solar module, at present the basic technology that adopts mainly by battery detecting, positive welding, back serial connection, lay, several procedures such as lamination, unhairing limit, rim frame, welding terminal box and follow-up test form.This wherein, the effect of lamination operation is that the battery that lays is put into laminating machine, by vacuumizing the air in the assembly is extracted out, heating makes the EVA fusing that battery, glass and backboard are bonded together then; Assembly is taken out in cooling at last, and good laminating technology not only can make the life-span of solar cell be guaranteed, but also has strengthened the resistance intensity of battery.This shows that the lamination operation has critical meaning for the end product quality of final solar cell, does not have good laminating technology, the light utilization efficiency of solar module, photoelectric transformation efficiency and service life just do not know where to begin yet.

Summary of the invention:

The present invention is equipped with line slideway in the four-post frame shelf structure, line slideway is fixed on the laminating machine bracing frame, and the movable part of line slideway is fixed on the loam cake crossbeam.When loam cake rose and descend, loam cake moved along line slideway.Because of line slideway being arranged, can overcome following problem well: 1. the stationarity problem that rises and descend as motion guide.When line slideway not being installed, the rising of loam cake and decline are very unstable, swing.2. swing when rising and descending because of loam cake, can add the wearing and tearing of large tank, reduce the service life of equipment.Since complete process of the present invention, reliable in quality, and fault rate is low, is fit to be extensive use of in China's production solar cell device industry.

In order to realize the purpose of foregoing invention, the technical solution used in the present invention is:

The present invention adopts in the four-post frame shelf structure line slideway is housed, (as Fig. 1).Line slideway is fixed on the bracing frame of laminating machine, loam cake is fixed on the line slideway active unit by the loam cake crossbeam.Oil cylinder drives the loam cake crossbeam and moves up and down, and then the drive loam cake moves up and down.

Beneficial effect of the present invention:

1. the present invention is equipped with line slideway in the four-post frame shelf structure, and the rising of loam cake and the stationarity of decline are good.

2. loam cake rising and decline can not swing, and have reduced the wearing and tearing of oil cylinder, have improved the service life of equipment.

Description of drawings:

Fig. 1 is an overall structure schematic diagram of the present invention;

Fig. 2 is the enlarged drawing of lamination section among Fig. 1;

Fig. 3: the schematic diagram (the part figure of Fig. 2) that line slideway is housed in the four-post frame shelf structure;

The specific embodiment:

Below just this novel laminating machine do concrete introduction.Because the frame for movement of oily zone of heating press and electric heating layer press is being consistent substantially, and the mounting technique of its line slideway is identical, so the present invention is described together with regard to the mounting technique of the line slideway of two kinds of laminating machinees.As (Fig. 1) is the general assembly drawing of novel laminating machine, (wherein figure (2) is the enlarged drawing of figure (1) lamination section).

As figure (1), novel electric heating layer press is mainly formed by three sections, is respectively loading bay 1, lamination section 2, discharge pedestal 3.

Acting as of loading bay can lie against the solar module that lays on the loading bay in advance.Loading bay: loading bay bracing frame 5Constitute the loading bay main body frame, control system 6, controllable silicon and transformer 15, the charging motor 7Usually be installed in its inside.Control system 6, be that the core of laminating machine is used to control mechanical movement and lamination process.Controllable silicon and transformer 15The upstream is controlled by control system 6, the downstream connects heating system, assists control system 6Carry out controlled heating.The charging table top 4(transport tape) is positioned at the loading bay bracing frame 5Top, by the charging motor 7Drive the motion of roller bearing rotation causing transport tape, reach the purpose of charging.

The lamination section is the key component of full-automatic laminating machine, lamination section bracing frame 8Mainly be fixed with lamination section motor 11, loam cake 9, line slideway 10, cylinder 20, lower chambers 21Loam cake 9Rising and decline pass through cylinder 20The piston motion control is in order to guarantee loam cake 9The stationarity that rises and descend, loam cake 9By the loam cake crossbeam 18Be fixed on line slideway 10Movable block on.The silica gel plate clamping plate 17And the silica gel plate press box cooperates hook 16, Silicone Rubber is fixed and is wrapped loam cake 9Lower surface.The chief component of lower chambers is the lower chambers vacuum system, and described lower chambers vacuum system mainly is made up of the steel plate of lower chambers sealing ring, hot plate, heater, alumina silicate light-weight brick, thermocouple and band spring.During work, loam cake rises, thereby battery component transports into the lamination section by the rotation of lamination section motor belt, and loam cake descends, and carries out lamination.

Discharge pedestal is mainly by the discharge pedestal support 13, the discharging motor 12And discharging table top 14Form.After lamination finishes, the discharging motor 12Drive the roller bearing rotation and cause conveyer belt, reach the purpose of discharging.
