Description
Technical field
The present invention relates to the production technology of photovoltaic module, particularly a kind of excessive adhesive process of photovoltaic module group frame.
Background technology
Photovoltaic module mainly is comprised of glass, EVA, cell piece, backboard and frame, in the production process of photovoltaic module, first by EVA with the cell piece double team between glass and backboard, form laminated sheet (also claiming the photovoltaic module semi-finished product), then frame is assembled into final formation photovoltaic module on the laminated sheet.
The detailed process of photovoltaic module group frame is: (1) does fluid sealant with silica gel, and the glue injecting head of using by injecting glue is filled in fluid sealant in the mounting groove of frame; (2) mounting groove of frame is sleeved on the edge of laminated sheet (edge that is laminated sheet is pressed in the mounting groove of frame) with frame loader, the fluid sealant in the mounting groove is spilled over to the notch edges of mounting groove, forms the sealed insulation layer at glass plate and backboard; (3) by transfer matic photovoltaic module is delivered to confined chamber, solidified fluid sealant through 4 ~ 6 hours.In the whole process of this photovoltaic module group frame, all need control the excessive glue effect of fluid sealant, sealed insulation with final assurance laminated sheet, so, the process of this photovoltaic module group frame and the excessive glue effect of assurance is the excessive adhesive process process of photovoltaic module group frame namely, wherein, the glue effect of overflowing refers to the slit of laminated sheet and frame mounting groove, the degree of depth that is inserted into the contact fluid sealant with clearance gauge is no more than 4mm, the backboard face of laminated sheet has fluid sealant evenly to overflow simultaneously, does not allow the phenomenon of starved, bubble, crimping.Enough glue amounts can guarantee insulation effect, but easily cause open defect, need the finishing cleaning, if the sealed insulation effect is bad, will cause photovoltaic module wet insulation resistance not up to standard, have potential safety hazard and reduce photovoltaic module useful life.Is what kind of requirement it (that the resulting excessive glue effect of the excessive adhesive process of existing photovoltaic module group frame does not reach above-mentioned excessive glue effect usually? how judging with bad well of the glue effect of overflowing? could the glue amount of overflowing obtain?, specifically there is following defective:
(a) such as Fig. 1-shown in Figure 4, during injecting glue, the exit face of glue injecting head 1 is the inclined-plane 11 of an inclined angle alpha, so that during injecting glue, glue injecting head 1 is from take too much space in mounting groove 21, finally not only cause the injection rate of fluid sealant 3 in mounting groove 21 few, and formed fluid sealant 3 upper surfaces also are the inclined-plane that an inclination angle is α, when laminated sheet 5 be pressed into mounting groove 21 interior after, overflowing of fluid sealant 3 is inhomogeneous with making, usually also will once manually mend glue with the assurance insulated enclosure, and manual benefit glue is high to operator's proficiency requirement, success rate is low again; Simultaneously, because the height h on the outlet inclined-plane 11 of glue injecting head 1 is little, so after injecting glue was finished, piled up in the exit of glue injecting head 1 also easy sealed glue parcel, if sealing glue solidifying will further affect the injecting glue effect and the glue weak effect that finally causes overflowing; And in order to reduce this impact, often the outlet of glue injecting head 1 is cleared up with regard to needing;
(b) as shown in Figure 5, when framing up, laminated sheet 5 is placed the Lifting platform of frame loader, again frame 2 is placed on the briquetting 4 of laminated sheet 5 four edges on the frame loader, drive briquetting 4 by frame loader the mounting groove 21 of frame 2 is inserted in laminated sheet 5 edges, at this moment, because the extruding of laminated sheet 5, fluid sealant 3 in the mounting groove 21 will overflow from the slit of 21 of laminated sheet 5 and mounting grooves, even be spilled over to each briquetting 4 from four edges of photovoltaic module 6 and pile up and solidify, evenness when often cleaning is not organized frame with impact, 5 generation steps of frame 2 and laminated sheet or excessive gap affect the overall dimension of photovoltaic module 6; And in order to reduce this impact, often each briquetting 4 is cleared up with regard to needs;
(c) as shown in Figure 6, during conveying, for the ease of the operation adjustment and consider the photovoltaic module of different size specification, transfer matic is resolved into a plurality of transfer matics unit 7, photovoltaic module 6 continues to transmit by the crawler belt 71 on each transfer matic unit 7 and carries.When although photovoltaic module 6 is carried in each transfer matic unit 7, only 2 contacts produce carrying capacity to crawler belt 71 with frame, but transmit the gap owing to existing between each transfer matic unit 7, crawler belt 71 on the transfer matic unit 7 is easy to contact laminated sheet 5, cause the gap between laminated sheet 5 and the mounting groove 21 to change, uncured fluid sealant 3 is prone to tomography, again overflows, and pollutes crawler belt 71 and photovoltaic module 6, also causes the phenomenons such as starved, insulated enclosure be bad; In addition, as shown in Figure 7, the needs of arranging for adapting to frame loader and transfer matic, sometimes need in transfer matic, to arrange a pair of orthogonal transfer matic unit 7, make the conveying of photovoltaic module 6 flow to vertical turn, these 7 gaps, a pair of orthogonal transfer matic unit are larger, also because the impact of crawler belt 71 steering forces, photovoltaic module 6 vertical turn transition herein is very not steady, is easy to cause fluid sealant 3 unstable overflowing yet; Also be, at fluid sealant 3 in the uncured time, the excessive adhesive process method of conventional photovoltaic assembly is when transmission, carrying assembly, all easily cause 5 frequent relative motions of frame 2 and laminated sheet, cause fluid sealant 3 controllably not overflow, increased the workload of follow-up repairing fluid sealant 3 or affected the quality of photovoltaic module 6.
Summary of the invention
Technical problem to be solved by this invention, just provide a kind of excessive adhesive process of photovoltaic module group frame, to form the excessive glue effect of good fluid sealant, guarantee the insulated enclosure of photovoltaic module, greatly reduce simultaneously the number of times of cleaning fluid sealant, improved the production efficiency of photovoltaic module.
