Abstract
The utility model discloses a manipulator for preventing a silicon chip box from being reversed and relates to the technical field of manufacturing equipment for solar cells, which comprises a manipulator body. The manipulator body is fixedly provided with a photoelectric sensor. The photoelectric sensor is electrically connected to a PLC controller arranged on the manipulator body through a photoelectric sensor circuit. A reflective film is attached onto the side surface of the silicon chip box. The light emitted by the photoelectric sensor is directly projected onto the reflective film, and then the light is reflected by the reflective film to be projected to the photoelectric sensor. According to the technical scheme of the utility model, the manipulator is additionally provided with the photoelectric sensor and the reflective film matched with the photoelectric sensor, so that the silicon chip box is effectively prevented from being placed reversely. Therefore, silicon chips are prevented from being damaged. The production stability is improved and the production cost is lowered.
Description
Technical field
The utility model relates to the making equipment technology field of solar battery sheet, relates in particular to a kind of manipulator that prevents from putting back silicon chip film magazine.
Background technology
In solar energy industry, the first operation that polycrystal silicon cell is manufactured is making herbs into wool, and making herbs into wool operation is exactly to utilize the damage layer of silicon chip, and the mixed solution by nitric acid and hydrofluoric acid carries out making herbs into wool to silicon chip surface.Making herbs into wool operation is a core procedure in manufacture of solar cells process, it is the damage layer that utilizes silicon chip, mixed solution by nitric acid and hydrofluoric acid carries out making herbs into wool to silicon chip surface, at silicon chip surface, form rugged surface and a large amount of holes, increase the light-receiving area on cell piece surface, reduce reflectivity, thereby improve the photoelectric conversion efficiency of solar cell.Its main process: WTS loads polysilicon chip → HNO3, HF making herbs into wool → air knife 1 → flushing 1 → KOH corrosion → air knife 2 → flushing 2 → HF, HCl cleaning → air knife 3 → flushing 3 → stainless steel air knife drying → WTS unload polysilicon chip.
Qualified polysilicon chip is loaded in film magazine and is sent to diffusing procedure, after diffusion technology completes, proceeds to wet method operation putting into film magazine, then by WTS manipulator, imports next operation into and produces.At the above-below direction through these operation silicon chip film magazines, must remain unanimously, because the polysilicon chip that starts to produce from making herbs into wool operation only has the effect of one side making herbs into wool best, so diffusion, plated film all will carry out at this face.Whichever process puts back all can be on the efficiency of silicon chip and mass formation impact.
Relational language is explained, RENA etching device: world-famous solar facilities manufacturer; The full-automatic loading and unloading manipulator of WTS:RENA equipment; Film magazine: the apparatus for placing of polysilicon chip, in (100/box) production, we are also referred to as " boat ".
Utility model content
Technical problem to be solved in the utility model is to provide a kind of manipulator that prevents from putting back silicon chip film magazine, described manipulator is by increasing photoelectric sensor and reflective membrane with matching, can effectively prevent that silicon chip film magazine from putting back, cause silicon chip to damage, improve the stability of production and the quality of product, fallen production cost.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of manipulator that prevents from putting back silicon chip film magazine, comprise manipulator body, it is characterized in that: on described manipulator body, be fixed with photoelectric sensor, photoelectric sensor is electrically connected to the PLC controller on manipulator body by photoelectric sensor circuit, the side of silicon chip film magazine is pasted with reflective membrane, the light of the transmitting of described photoelectric sensor is directly projected to reflective membrane place, and reflective membrane reflexes to photoelectric sensor place by above-mentioned light.
Further preferred technical scheme is: described reflective membrane is fixed on the bottom of described silicon chip film magazine side.
Further preferred technical scheme is: described photoelectric sensor adopts HY860 type.
The beneficial effect that adopts technique scheme to produce is: described manipulator increases photoelectric sensor and the photoelectric sensor circuit being equipped with mutually with it on the manipulator body of prior art, and in the side of silicon chip film magazine, the luminescent film corresponding with photoelectric sensor is installed, if film magazine puts back, photoelectric sensor does not receive the light signal returning, PLC controller on manipulator body is exported alarm so, remind staff to note, if film magazine correct position, the light signal of photoelectric sensor transmitting is reflected by reflective membrane, then photoelectric sensor receives light signal, manipulator is normally worked.Described manipulator can effectively prevent that silicon chip film magazine from putting back, and causes silicon chip to damage, and has improved the stability of production and the quality of product, has fallen production cost.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is a kind of typical structure block diagram of photoelectric sensor circuit in the utility model;
Wherein: 1, manipulator body 2, photoelectric sensor 3, silicon chip film magazine 4, reflective membrane.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
A lot of details have been set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization without prejudice to the utility model intension in the situation that, so the utility model is not subject to the restriction of following public specific embodiment.
For the pointed problem of background technology, the application discloses a kind of manipulator that prevents from putting back silicon chip film magazine, as shown in sketch 1, comprises manipulator body 1, and described manipulator body is same as the prior art, at this, does not repeat.The application's inventive point is: on described manipulator body 1, be fixed with photoelectric sensor 2, the form of photoelectric sensor has multiple, photoelectric sensor is used transmitting-receiving integrated photoelectric sensor in this application, concrete described photoelectric sensor in this application can adopt HY860 type, it should be noted that photoelectric sensor is not limited to above-mentioned model, those skilled in the art can carry out suitable type selecting as required.
Photoelectric sensor 2 is electrically connected to the PLC controller on manipulator body by photoelectric sensor circuit, be illustrated in figure 2 the winding diagram of a kind of typical photoelectric sensor and PLC controller, it should be noted that the winding diagram shown in Fig. 2 is same as the prior art, inventive point of the present utility model is the application of transducer, and does not lie in circuit design.The side of silicon chip film magazine 3 is pasted with reflective membrane 4, the light of described photoelectric sensor 2 transmittings is directly projected to reflective membrane place, reflective membrane reflexes to photoelectric sensor by above-mentioned light, the size of reflective membrane is not greater than the fixed area on silicon chip film magazine, too not little otherwise transducer is difficult for shining, and generally described reflective membrane is fixed on the bottom of described silicon chip film magazine side.
