Abstract
The invention discloses a quickly-changed silicon chip film-coated single-faced hanging hook assembly and a mounting method thereof. The quickly-changed silicon chip film-coated single-faced hanging hook assembly comprises single-faced hanging hooks and liner plates; pressed lug bosses are arranged at top ends of two ribbons; bending grooves are arranged outside the two ribbons at equal height; the arranging positions of the bending grooves have the requirement that the distance from the inner side to the bottom side of a positioning groove is equal to the summation of the thicknesses of the two line plates and the thickness of a longitudinal rod after the pressed lug bosses are bent towards the inner side by 90 degrees; the liner plates are I-shaped; ribbon grooves are arranged on two sides of the liner plates; the single-faced hanging hooks are matched with the liner plates for use and are fixed on the longitudinal rod through the two liner plates; the two ribbons cannot directly act on the longitudinal rod in the tightening and releasing processes; and the arrangement of the bending grooves and the pressed lug bosses is convenient for the quick tightening and detaching of the single-faced hanging hooks and cannot cause the damage to a silicon chip bearing frame and can reduce the probability of depositing a silicon nitride layer on the back side of the silicon chip.
Description
[technical field]
The present invention relates to a kind of silicon wafer carrier that solar battery sheet PECVD plated film is used, relate in particular to the hook on the silicon wafer carrier.
[background technology]
PECVD is the abbreviation of solar battery sheet plasma chemistry deposition plating technology, in the production process of solar cell, to silicon chip film-coated be the gordian technique that improves the solar cell assimilated efficiency, opto-electronic conversion electricity generating principle according to silicon chip, irradiate light can produce reflection to silicon chip, the optical loss of silicon chip can make the output of solar cell be lower than ideal value, silicon chip film-coated technology is to improve the mature technology of solar cell assimilated efficiency, in solar cell industry production, be used widely, can form one deck antireflective coating at silicon chip surface by PECVD.
In the PECVD coating process, must use silicon wafer carrier, used silicon wafer carrier as shown in Figure 1, it is made up of single-faced hanging hook 1, two-sided hook 2 and bearing frame 3, bearing frame 3 is put together by longitudinal rod 31 and transverse bar 32, single-faced hanging hook 1 is installed on the longitudinal rod 31 of the left and right sides, and 2 of two-sided hooks are installed on other longitudinal rod 31.Silicon chip 4 block-by-blocks to be coated are lain on the silicon wafer carrier, silicon chip 4 is held up the level of, silicon chip 4 downward diffusingsurfaces are carried out plated film by hook.Existing single-faced hanging hook as shown in Figure 2, it is a sheet structure, by hook 11, hook body 12, locating slot 13, band 14 is formed, hook 11 is positioned at a side of hook body 12 bottoms, locating slot 13 is positioned at the top of hook body 12, and be between two bands 14, single-faced hanging hook 1 is installed on the longitudinal rod 31 of silicon wafer carrier by locating slot 13, its mode of installing and fixing is: locating slot 13 is installed on the longitudinal rod 31, with pliers two bands 14 are hinged together then, thereby single-faced hanging hook 1 is fixed on the longitudinal rod 31, when hinged fastening hook, two bands 14 will inevitably produce tightening force and friction to longitudinal rod 31, because the silicon chip bearing frame made by the carbon element complex fiber material, the installation of hook tighten up with demolishing process in, 14 pairs of longitudinal rods of band 31 can produce bigger damage, this must quicken the damage of silicon wafer carrier, shortens its work-ing life.At present, be two months the work-ing life that silicon wafer carrier is general, and production consumes bigger, because the price of silicon wafer carrier is higher, so the ratio of silicon wafer carrier consuming cost in coating cost is higher.
In process of plating, silicon chip to be coated is to lie on the silicon wafer carrier, and hold up the level of by four hooks, hook fixed tightness directly influences the distance between hook top and the longitudinal rod bottom surface, thereby change the gap between silicon chip and the silicon wafer carrier, increased the probability of silicon chip backside deposition silicon nitride layer, there is silicon nitride layer at the silicon chip back side will produce detrimentally affect to the printing sintering of the later process aluminium back of the body.Simultaneously, in coating process, all can deposited silicon nitride at silicon wafer carrier and hook surface, according to the coating process requirement, after finishing, the hook on the silicon wafer carrier must be removed plated film, use the HF solution (5%) of lower concentration to soak then and adhere to silicon nitride on it with removing, otherwise hook will be fallen by the HF solution corrosion in immersion process, so not only to consume HF solution, but also need to remove still last corrosive hook partly, also increased cost and the difficulty of back road simultaneously to HF solution environmental protection treatment.
[summary of the invention]
In order to overcome the deficiency of existing single-faced hanging hook, a kind of quickly-changed silicon chip film-coated single-faced hanging hook assembly and installation method thereof have been the purpose of this invention is to provide, adopt this single-faced hanging hook assembly, not only be convenient to Fast Installation and dismounting, and install and remove and can not produce damage to the silicon chip bearing frame, can also be reduced in the probability of silicon chip backside deposition silicon nitride layer significantly.
Quickly-changed silicon chip film-coated single-faced hanging hook assembly of the present invention, it is characterized in that, it comprises single-faced hanging hook and backing plate, described single-faced hanging hook is by hook, the hook body, locating slot, band, oppression boss and bending groove are formed, hook is arranged on a side of hook body bottom, locating slot is positioned at the top of hook body, and be between two bands, oppression boss is arranged on the top of band, the outside of two bands equal altitudes be provided with the bending groove, the status requirement of offering of bending groove is: when oppression boss along the bending groove to the inside behind 90 ° of the Edge Bends, inner side edge equals two plate thickness and longitudinal rod thickness sum to the distance on locating slot base; Described backing plate is " worker " font, both sides at backing plate are provided with strap slot, the width of strap slot is suitable with the thickness of band, and the distance between the inner side edge of distance between the bottom land of two strap slot and two bands is suitable, and the top and distance longitudinal rod base of hook is less than or equal to the thickness of silicon chip.
Owing to changed the structure of single-faced hanging hook, and two backing plates have been set up, single-faced hanging hook when mounted, the end face of longitudinal rod all contacts with single-faced hanging hook by backing plate with the bottom surface, two bands of single-faced hanging hook tighten up with demolishing process in all act directly on the backing plate, therefore, can not produce damage, thereby can increase substantially the work-ing life of silicon wafer carrier longitudinal rod.Since the outside of two bands equal altitudes offered the bending groove, top at band is provided with oppression boss, the installation of single-faced hanging hook if with pliers with the oppression boss of two bands upper end along bending groove 90 ° of Edge Bends to the inside, in the time will removing, need only oppression boss restored.Because single-faced hanging hook is identical with two-sided hook structure, so just can make the top of all hooks equivalent with the distance of longitudinal rod bottom surface, in coating process, because the upper surface of silicon chip is not less than the bottom surface of longitudinal rod, so just can be reduced in the probability of silicon chip backside deposition silicon nitride layer significantly, adopt this single-faced hanging hook assembly, not only be convenient to Fast Installation and dismounting, and install and remove and can not produce damage the silicon chip bearing frame, the probability of silicon chip backside deposition silicon nitride layer can also be reduced in significantly, the coating process requirement can be satisfied better.
