Description
Technical field
The invention belongs to battery core manufacturing technology fields, and in particular to a method of battery core is detected based on X-Ray.
Background technique
The efficient green energy of the battery core as a new generation, with small in size, operating voltage is high, energy density is big, memoryless
The advantages that effect, is widely used in all trades and professions.And in the manufacturing of battery core, battery core generally requires pair after packaging
It carries out X-Ray detection and (utilizes the transmission principle of X-ray under the premise of not damaging battery core, battery core is penetrated, according in battery core
Each material obtains battery core clearly image of internal structure, to quickly detect inside battery core to the difference of X-ray degree of absorption
Flaw, to judge whether battery core meets the requirements), still, in the prior art, battery core manufacturer in this process, can be first with
Automatically X-ray detection machine carries out Preliminary detection, and not qualified battery core is passed through manual X-Ray detection machine again and is carried out manually
Measurement and judgement, are finally confirmed whether it is qualification by visual inspection again, there are more drawbacks for such process:
1) it after automatic X-ray test, crosses and kills that (" cross and kill " refers to that when determining one product quality, judgement data are in critical
Point, in order to guarantee that this process exports the product for being all, just those not only seemed but also to seem that bad product is determined as bad
Product) battery core can enter in manual X-Ray and subsequent visual inspection, wherein cross kill rejected product in battery core in appearance with normal electricity
Core does not have significant difference, it is easy to be mixed into qualified battery core, can not choose in appearance full inspection;
2) current testing process is mainly artificial judgment, cannot achieve the judgement of objective, and as shipment standard
Foundation;
3) cost of equipment of X-Ray detection and labour cost are huge manually, and production efficiency is low.
Based on this, it is badly in need of a kind of method of accurate, efficient X-Ray detection battery core.
Summary of the invention
It is an object of the invention to: in view of the deficiencies of the prior art, and a kind of side based on X-Ray detection battery core provided
Underproof battery core can be effectively detected out in method, this method, prevent from being mixed into normal product, while the objective judgement as system,
Artificial subjective factor is reduced, the confidence level of detection is improved, in addition, also improving production efficiency, saves production cost.
To achieve the above object, the present invention adopts the following technical scheme:
A method of battery core is detected based on X-Ray, comprising the following steps:
S1: Preliminary detection: automatic X-Ray machine obtains the pictorial information of battery core to be measured, and is examined automatically to the angle of battery core position
It surveys, visual inspection area can be gone to by under through the qualified battery core of detection, and underproof battery core can then be sent to the detection of next step, meanwhile,
The pictorial information of underproof battery core is uploaded in the database of system;
S2: system determines: the pictorial information of the underproof battery core of S1 in system called data library automatically generates virtual screen
Ruler, which can measure the specification at each position in battery core pictorial information whether in the range of technique requires, if requiring
In the range of be then determined as qualification, and will be qualified battery core under go to visual inspection area, if not being judged to not conforming to if desired range
Lattice, and underproof battery core is offline to defective products storehouse;
S3: visual inspection: carrying out visual inspection to the qualified battery core in S1 and S2, offline if not abnormal to arrive finished bin;
S4: reinspection: primary automatic X-ray detection is carried out again before the final shipment of battery core finished product, if it find that there is unqualified battery core
It falls into, is then chosen, and carry out production improvement.Battery core finished product is rechecked, unqualified battery core has been further prevented to infiltrate
The possibility of normal product, improves the quality of battery.
It further include the bar code letter of battery core as the improvement of the method for the present invention based on X-Ray detection battery core, in S1
Breath, wherein the bar code information of qualified battery core can be uploaded in database, and underproof battery core, then can be by bar code information
It is uploaded in database together with pictorial information.
As the improvement of the method for the present invention based on X-Ray detection battery core, system is inputting or is scanning electricity in S2
When the bar code information of core, the pictorial information of corresponding battery core can be obtained in the database.
As the improvement of the method for the present invention based on X-Ray detection battery core, the pictorial information of battery core includes camera lens
The path of multiplying power, the size of measurement and picture storage.
As the improvement of the method for the present invention based on X-Ray detection battery core, system can be according to the battery core of calling
The real lens multiplying power of picture, automatic calibration generate the virtual screen ruler of phase same multiplying.
It further include that item is carried out to battery core in S3 as the improvement of the method for the present invention based on X-Ray detection battery core
The scanning of code information, wherein testing result is only shown by lower turn of battery core of S1, and testing result is then shown by lower turn of S2 of battery core
With the pictorial information of battery core, system can intercept unqualified battery core, and qualified battery core then directly offline can arrive finished bin.
As the improvement of the method for the present invention based on X-Ray detection battery core, system is determined as to battery core in S2
The judgement of the battery core in database can be changed while qualified as a result, and recording personnel and the temporal information of operation.It is arranged in this way
The link to go wrong can be rapidly traced in subsequent operation, to preferably improve to production, improve production
Excellent rate.
The beneficial effects of the present invention are: the present invention is effectively prevented by Preliminary detection, system judgement, visual inspection and reinspection
Only underproof battery core is mixed into qualified battery core, improves the quality of battery core, while the objective judgement as system, reduces people
The subjective factor of work, improves the confidence level of detection, in addition, also improving production efficiency, saves production cost.
