Technical field
The utility model relates to solar cell and makes the field, relates in particular to a kind of cleaning machine that is used for the injection apparatus of cleaning machine and uses this injection apparatus.
Background technology
In solar cell manufacturing process, can use a lot of cleaning machines.With horizontal dephosphorization silex glass cleaning machine is example, the conveying roller group that horizontal dephosphorization silex glass cleaning machine generally includes rinse bath and is used to carry silicon chip, thereby being contacted with cleaning fluid such as dilute hydrofluoric acid solution, silicon chip utilize the reaction of dilute hydrofluoric acid solution and phosphorus silicon compound to remove phosphorosilicate glass, and then through rinsed with deionized water.Phosphorosilicate glass is meant that when using P type silicon as the battery matrix material, in diffusion process, phosphorus and silicon are at one deck compound of silicon chip surface formation.This layer material can influence the incident of sunshine, and can reduce the contact performance of silicon chip surface and electrode, causes battery quality to descend, so need to remove this layer phosphorosilicate glass.
As shown in Figure 1, horizontal dephosphorization silex glass cleaning machine often adopts spray regime that the silicon chip on the conveying roller group is cleaned.Silicon chip 11 is during by its last one rinse bath, the discharge that nozzle 121 from the jet pipe 12 of injection apparatus sprays is relatively large, and the water column of nozzle 121 ejection and the angle between the silicon chip to be spray angle be generally 45 degree, the impulse force that makes silicon chip 11 be subjected to is bigger, be easy to cause fragment and cause damage, therefore be necessary to improve.
In addition, if adopt the method that reduces discharge to reduce the impulse force that silicon chip is subjected to, the cleaning performance of silicon chip 11 can be affected; If the position of mobile jet pipe 12 because the operating space is narrow and small, need be transformed cleaning machine self, improvement cost is higher.
The utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model provides a kind of cleaning machine that is used for the injection apparatus of cleaning machine and uses this injection apparatus, its can under the prerequisite that does not change discharge, reduce to the impulse force of silicon chip so that reduce fragment rate and improvement cost lower.
To achieve these goals, the utility model provides a kind of injection apparatus that is used for cleaning machine, comprise a plurality of nozzles, jet pipe and have the extension rod of interface channel, described nozzle and jet pipe are connected by extension rod, described extension rod comprises nozzle linkage section and jet pipe linkage section, and the angle between described nozzle linkage section and the described jet pipe linkage section is greater than 90 degree and less than 135 degree.
As preferably, described jet pipe linkage section is provided with the external screw thread connector with described jet pipe coupling, and described nozzle linkage section is provided with the internal thread connecting hole with described nozzle matches, and extension rod is fixedly connected with jet pipe and nozzle respectively by thread connecting mode.
As preferably, described angle is 120 degree.Thereby make spray angle become 30 degree,, therefore can under the prerequisite that does not change discharge, reduce impulse force silicon chip owing to reduced spray angle by 45 degree of the prior art.
As preferably, the end of described nozzle linkage section also is provided with the seal groove of placing sealing ring, and the internal diameter of described seal groove is greater than the internal diameter of described internal thread connecting hole.In described seal groove, place sealing ring, can reach good sealing effectiveness behind the installation nozzle; Equally, also can be provided with sealing ring at the jet pipe linkage section.
To achieve these goals, the utility model also provides a kind of cleaning machine, comprises rinse bath and conveying roller group, also comprises above-mentioned injection apparatus, and it is used to clean the silicon chip on the described conveying roller group.
As preferably, a plurality of nozzles of described injection apparatus are separately positioned on the both sides up and down of described conveying roller group.
As preferably, described conveying roller group a plurality of nozzles of both sides up and down is that symmetrical expression distributes.
Compared with prior art, the utility model has the advantages that: because the injection apparatus that is used for cleaning machine of the present utility model has designed extension rod dexterously, under the prerequisite that does not change discharge by reducing the spray angle of nozzle, solve the problem that impulse force causes the workpiece fragment more greatly well, reduced fragment rate.Cleaning machine can use the extension rod of different angles to change spray angle to satisfy cleaning requirement as long as use this injection apparatus according to actual needs, do not need cleaning machine self is improved, so improvement expenses is lower, has very strong practicality.

The specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Extremely shown in Figure 4 as Fig. 2, the injection apparatus of present embodiment comprises a plurality of nozzles 121, jet pipe 12 and extension rod 2, extension rod 2 inside are provided with interface channel, nozzle 121 and jet pipe 12 are connected by extension rod 2, and the liquid that is used for cleaning silicon chip in the jet pipe 12 is sprayed by nozzle 121 through the interface channel of extension rod 2.
Certainly, the angle between nozzle linkage section 22 and the jet pipe linkage section 21 can be greater than 90 the degree and less than 135 the degree in arbitrarily angled, can select according to actual needs.For convenience, below only with angle be 120 the degree describe, other spray angle principle is identical.
For make nozzle 121 with can reach good sealing effectiveness after internal thread connecting hole 221 is connected, the end of nozzle linkage section 22 also is provided with the seal groove 222 of placing sealing ring, the internal diameter of seal groove 222 is greater than the internal diameter of internal thread connecting hole 221, thus, sealing ring (not shown) can be placed in the seal groove 222, connect nozzle 121 again, reach good sealing effectiveness; Same consideration also can be provided with sealing ring (not shown) on jet pipe linkage section 21.
As can be seen from Figure 2, the external screw thread connector of extension rod 2 211 connects jet pipes 12, and the internal thread connecting hole connects nozzle 121, makes the spray angle of nozzle 121 become 30 degree by 45 degree of prior art.By using extension rod 2, under the constant situation of discharge, reduced spray angle, reduced the impulse force of injection water, thereby made the fragment rate of silicon chip 20 reduce greatly silicon chip 20.
Cleaning machine of the present utility model comprises that rinse bath, conveying roller group and above-mentioned being used to clean the injection apparatus of the silicon chip on the described conveying roller group.A plurality of nozzles of injection apparatus are arranged on the both sides up and down of conveying roller group respectively symmetrically, and the silicon chip 20 of process is cleaned.
The injection apparatus of above-mentioned cleaning machine, do not need to change the position of jet pipe 12, only need between jet pipe 12 and a plurality of nozzle 121, to increase extension rod 2 and can reduce spray angle, reduced the impulse force of injection water, thereby made the fragment rate of silicon chip 20 reduce greatly silicon chip 20.And owing to do not need the cleaning machine main body is transformed, improvement cost is lower, has very strong practicality.
Above embodiment is an exemplary embodiment of the present utility model only, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can make various modifications or be equal to replacement the utility model in essence of the present utility model and protection domain, this modification or be equal to replacement and also should be considered as dropping in the protection domain of the present utility model.
