Description

The error-preventing method of solar cell classification

Technical field

When the present invention classifies to solar cell about one, prevent because artificial careless mistake, and cause the method for solar cell classification error.

Background technology

In manufacture of solar cells process, due to the difference slightly of various working conditions and parameter, also can affect every a collection of characteristic of solar cell of producing and quality, such as transfer power, color, impedance operator etc.And the price of solar cell can be distinguished to some extent along with grade difference, its application also differs widely.Such as: the best solar cell of photoelectric transformation efficiency can be used for forming solar panels module, and its price is also the most expensive; The poor solar cell of conversion efficiency can only be applied to the more cheap people's livelihood article such as key-ring, flashlight.

Current solar cell classification step is as shown in the step S100～S103 in Fig. 1.Classifier can be by finished product according to default condition, do the classification of each grade, it is by tape transport solar cell, and on transport path, carry out various detections, and then the solar cell after detecting is divided and delivers to the collection port (rank port) that represents each grade, be collected in angle box (bin).

When angle box, fill after solar cell, conveyer belt can stop automatically, and with warning cresset prompting operation person, full angle box is taken away.Then, operator can print the label paper that will be affixed on described angle box, and it comprises the important informations such as efficiency, grade, sheet number, for the identification of subsequent treatment.When operator places another empty angle box at the collection port of vacating, and press startup button, conveyer belt just continues action.

Please refer to Fig. 2, is the graph of a relation of solar cell number and grade, be conversion efficiency using solar cell as grade scale, every 0.2% is divided into one-level, is altogether divided into 96 grades.The distribution of grades of solar cell becomes Gaussian distribution.In other words, in assorting process some etc. rank at the angle of mediant box, can very fast filling, some will be waited for a long time and just can fill.Therefore, can for the angle box of each collection port, not label in advance, also can not prepare the angle box of equivalent, but after isogonism box fills, just grade label be sticked.

Such as grade is between 45～55, angle box can be filled very soon, so when when Zhong Youyi angle, these level region box is filled, operator, according to experience, can judge at another angle box in same region and also can fill very soon.In order to save time, operator can first put into sky angle box, and starts classifier continuation running, and after waiting for that another angle box is filled, operator holds the angle box of two different brackets again, to printing station, does finished product record.

But, because not representing, angle box itself when operator will stick the label corresponding with angle box, is easy to the identification mark of grade mix up, and cause product post sales, to suffer from customer complaint problem.Therefore, under existing board and technology, be necessary to develop a kind of error-preventing method, to solve foregoing problems.

Summary of the invention

Because above-mentioned problem, one of object of the present invention is to provide a kind of error-preventing method of solar cell classification, comprise: a classifier is provided, there is a link declaration bar code (binding barcode), and multiple collection ports, these collection ports are a corresponding address bar code respectively, and the corresponding solar cell grade of difference.Then, scan and link declaration bar code; Got angle box, there is one jiao of box bar code, scanned the address bar code of collection port and scanned described angle box bar code.

Empty angle box is placed in to described empty collection port, to set up the connection relationship of described address bar code and angle box bar code, repeats above-mentioned steps, until institute is free collection port to be free angle box.Then, start classifier, according to grade, send these solar cells to corresponding angle box.

When wherein one jiao of box is filled, classifier automatic pause, and give notice, operator moves to a printing station by full angle box, scans the angle box bar code of angle box, to produce and to print a grade label, to be affixed on described full angle box, cancel the connection relationship of described angle box bar code and address bar code simultaneously.

The present invention can reduce because of artificial careless mistake, cause solar cell grade to indicate problem wrong and customer complaint, and the cost that bar code identification system is used is lower, can therefore not cause the burden of manufacture of solar cells cost.

The specific embodiment

For above-mentioned purpose of the present invention, feature and advantage can be become apparent, below, according to the error-preventing method of solar cell classification of the present invention, especially exemplified by preferred embodiment, and coordinate appended relevant drawings, be described in detail below.

In the present invention, utilize bar code identification system to coordinate a server, do many-sided confirmation, prevent from, because of artificial careless mistake, causing solar cell grade to indicate wrong problem.

Please refer to Fig. 3 A, for method of the present invention is applied to the schematic diagram of solar cell classifier 3.Referring to Fig. 4, be flow chart of the present invention, first, provide a classifier 3, as step S300.

Classifier 3 comprises a conveyer belt 5, multiple collection port P1～P96, is positioned over angle box 35, a server 60 and a printing station 70 of collection port.The classifier 3 of the embodiment of the present invention is by the solar cell after detecting, and with conveyer belt 5 dispensings, to multiple collection port P1～P96, is loaded in angle box 35.

In conveyer belt 5 both sides of classifier 3, respectively post a link

declaration bar code

40A, 40B, so that the operator of both sides uses

bar code scanner

50A, 50B to scan separately.

Bar code scanner

50A, 50B and a server 60 are set up line 52, and to be set up or to be cancelled the connection relationship of angle box 35 and collection port P1～P96 by server 60, wherein, described server can be a manufacturing execution system (MES).

Bar code scanner

50A, 50B scan in the database that result can write server 60, and in input message, add a preamble, to distinguish, are the information which

bar code scanner

50A, 50B inputted.If while wherein having operator's operating sequence mistake, 60 of servers can empty the input message of this bar code scanner.

Collection port P1～P96 is a corresponding solar cell grade respectively, and has separately an address bar code 15.Please refer to Fig. 3 B, is the enlarged diagram of a collection port and angle box wherein, and each collection port P1 has a checkout gear 12 and an alarming device 10, and and server 60 set up line 17.Each collection port need be placed one jiao of box 35, and each angle box 35 has one jiao of box bar code 30.

In the embodiment of the present invention, be to carry out classification according to conversion efficiency of solar cell, every 0.2% establishes a grade, always has 96 grades, therefore, 96 collection ports is set.

Before operator is positioned over empty collection port by empty angle box 35, first scan and link

declaration bar code

40A or 40B, in order to declaration, to ensuing collection port address bar code 15 and angle box bar code 30 be done and be linked, as step S305.

Then, got angle box 35, as step S310, scanned the address bar code 15 of collection port and scanned the angle box bar code 30 of angle box 35, as step S315.In the embodiment of the present invention, and set and link

declaration bar code

40A or 40B is every is scanned once, only link an address bar code 15 and one jiao of box bar code 30 subsequently.Afterwards, empty angle box 35 is placed in to sky collection port P1, to set up the connection relationship of address bar code 15 and angle box bar code 30, as step S320, aforesaidly scans action and all by

bar code scanner

50A or 50B, completed.

In order to prevent that operator from misplacing collection port by the angle box 35 of calibration position, such as: bar code scanner 50B has declared that the angle box bar code 30 of angle box 35 and the address bar code 15 of collection port P1 link, but operator is misplaced angle box 35 in collection port P2, cause the situation of misclassification grade afterwards.

So, in the present embodiment, as long as empty angle box 35 1 is positioned over collection port P1, checkout gear 12 meeting automatic indicatings number, operator needs manual-lock cresset, and with notification server 60, the collection port that angle box 35 is put into is P1.At this moment, server is further confirmed the address bar code 15 that bar code scanner 50B scans again, the collection port P1 whether corresponding angles box 35 is put into, confirm errorless after, just build the connection relationship of setback bar code 30 and address bar code 15.

Then, judge whether that had sky collection port P1～P96 has had angle box 35, as step S325.If "No", repeating step S305～S325.If "Yes", starts classifier 3, according to extremely corresponding angle box 35 of grade dispensing solar cell, as step S330.

When wherein one jiao of box 35 is filled, the conveyer belt 5 meeting automatic pauses of classifier 3, and give notice with alarming device 10, such as: with cresset or the tinkle of bells, carry out hyperphoric another angle box 35 of notification operator, as step S335.

Now, operator can select whether to wait for that next angle box 35 fills, as step S340.Such as: after the angle of collection port P48 box 35 is filled, operator sees at the angle of collection port P50 box 35 and is also about to fill, and just can first at collection port P48, place new empty angle box 35, and start classifier 3, namely repeating step S305～S340.

Pay special attention to, in such cases, the address bar code 15 of collection port P48, simultaneously and an angle box bar code 30 that expires angle box 35 and an empty angle box 35 there is connection relationship.

After the angle of collection port P50 box 35 is filled, if operator no longer waits for next angle box, proceed step S345, namely all on hand full angle boxes 35 are moved to a printing station 70, scan the angle box bar code 30 of full angle box 35, to produce and to print a grade label, be affixed on angle box 35, just cancel the connection relationship of angle box bar code 30 and collection port P48 address bar code 15.When scanning angle box bar code 30, server 60 can show that angle box 35 original placed collection ports be P48 or P50, wrong to prevent that operator from pasting label.

So, even if when operator once takes multiple angles box 35 to do finished product and record to printing station 70, can not get grade wrong yet.And, after classifier 3 does not need all to wait for that operator completes printing at every turn, just continue to start, can make whole work flow rapider.

Certainly, also can optionally set an address bar code 15 once can only set up and link with an angle box bar code 30, because the collection port that classifier 3 must be all is all piled just and can be restarted, so can imperative operation person must first complete printing and label, just can carry out subsequent action.Because operator once can only take an angle box 35, also just effectively prevent the problem of misbrand.

In sum, the error-preventing method of solar cell classification of the present invention, by using bar code identification system, can solve the problems of the prior art easily, even if operator once takes multiple angles box, also can accurately do finished product grade record.In addition, the present invention not only method is easy, and the identification system cost using is lower, can therefore not cause integral production cost significantly to rise.

Though the present invention illustrates as above with preferred embodiments, so it not only terminates in above-described embodiment in order to limit the present invention's spirit with invention entity.All those skilled in the art, when understanding easily and utilize other element or mode to produce identical effect.Therefore not departing from the modification of doing in spirit of the present invention and category, all should be included in the protection domain of claim.
