Description

电泳涂装线电泳槽药液自动计算添加方法 技术领域
本发明涉及电泳涂装线电泳槽药液自动计算添加方法。
背景技术
电泳涂装线的电泳槽中存有药液，药液需要及时补充添加，电泳槽液中电泳漆成份在电泳槽液里的百分比要求稳定在一定范围，才能保证工件在电泳过程中电泳漆膜的质量。为了使工件的电泳漆膜的一致性，在其它参数不变的情况下，需要让电泳漆成份在电泳槽液里的百分比尽量的稳定。但是电泳漆成分会随着工件的电泳过程消耗，为了保证电泳漆成分在电泳槽液里的百分比稳定在合理范围，需要在所占百分比达到下限之前添加电泳漆到电泳槽中，且添加量不能超过电泳漆成份占电泳槽液百分比的上限。如果要让电泳漆成份在电泳槽液里的百分比变化很小，就需要减小上限和下限之间的范围，但这会造成检测和添加次数多和每次添加量少，使工作量大大增加。
为了减少工作量，目前采用的方法是统计出每天电泳漆的添加总量，通过设备定时定量往电泳槽内添加，这样可以减小电泳漆成份在电泳槽液里的百分比变化。
定时定量添加法，因为要先检测并统计计算出电泳漆成分在工件电泳过程中单位时间内的消耗量，按照计算出工件在电泳过程中单位时间内电泳漆的清耗量定时定量添加，但是不同的工件或同工件在不同电泳漆膜厚时单位时间内的消耗量也会变化，会造成添加量与消耗量不相同，导致电泳漆成份在电泳槽液里的百分比波动较大，需要技术人员不断检测统计计算更改定时添加时的添加量。

2)根据步骤1)所得电量值计算出电泳漆液的添耗量；
3)把步骤2)计算出的电泳漆液消耗量与设定的每次添加量比较，当消耗量与添加量相等时，启动电泳漆液加药泵添加设定的添加量，并重置(清零)电量消耗值。
4)重复步骤1)至步骤3)。
优选的，步骤2)中，在计算电泳漆液添耗量时根据输入的计算偏差修正添耗量。
本发明改变定时定量的添加方式，根据电泳漆在工件电泳过程中的消耗量与工件在电泳过程中所使用的电量之间的关系，实时采集工件在电泳过程中的电流值计算出电量值，再根据电量值计算出电泳漆的消耗量，当消耗量达到设定值时控制加药泵添加计算出的消耗量。
本发明是通过实时采集工件在电泳过程中的电流值计算出电量值，再计算出工件在电泳过程中实际的电泳漆消耗量，根据实际的消耗量进行添加，所以大大减小了添加量与消耗量之间的误差，使电泳漆成份在电泳槽液中的百分比更加稳定。
与现有的定时定量添加方式或人工添加方式相比，本发明的电泳槽药液自动计算添加方法，具有如下优点：本发明可以根据电泳槽的容积和电泳槽液里电泳漆成份的百分比允许的波动范围计算出设置定量添加量的多少，系统计算工件电泳过程中电泳漆液的实际消耗量，消耗量达到设置的添加量便开始添加。计算过程可以根据不同型号或品牌的电泳漆液设置计算比例偏差修正使计算结果与实际值误差降到最低，使添加量与实际消耗量误差减到最小。传统的定时定量或人工添加方式需要频繁的检测电泳槽液参数，计算出电泳漆液的消 耗量调整定时定量的添加量或人工添加。本发明只需技术人员进行少量的检测电泳槽液参数调整系统计算比例偏差修正参数即可，可以大大减小技术人员的工作量，同时可以使电泳槽液里电泳漆的百分比很稳定。
本发明通过采集工件在电泳过程中的电流值，根据时间计出消耗的电量，根据电泳漆成份消耗与消耗电量之量的关系统计算出电泳漆液的实际消耗量，且计算过程可以根据不同型号或品牌设定偏差比例修正，保证计算精度。同时可以设置定量添加量，只要消耗量达到每次添加量便开始添加，保证电泳槽液里电泳漆成份的百分比保持稳定。
