Description

一种压缩机注油检测方法
技术领域
本发明涉及一种检测,具体是指一种压缩机注油检测方法。
背景技术
在压缩机的生产过程中,需要检测压缩机的注油孔是否畅通。目前,在压缩机的生产线上通常采用人工观察的方式来检测,人工检测的方式不仅自动化程度不高,需要投入更多的人力资源,而且比较容易产生检测失误。压缩机的注油孔堵塞将直接影响压缩机的正常使用,因此注油孔检测失误将直接导致压缩机售出后不能使用。因此,提供一种检测准确率高且能自动检测压缩机的注油孔是否畅通的方法便是当务之急。
发明内容
本发明的目的在于提供一种压缩机注油检测方法,以期能自动且能准确的检测压缩机的注油孔是否畅通。
本发明通过下述技术方案实现:
一种压缩机注油检测方法,包括以下步骤:
(1)向压缩机注油孔中注油;
(2)使用光源同轴照射油孔;
(3)拍摄油孔中油面下降的图像;根据拍摄到油面下降的图像判定注油孔是否畅通。
进一步的,步骤(3)中根据拍摄到油面下降的图像判定注油孔是否畅通的过程为:拍摄的油面在图像上形成光斑,若光斑呈现出由模糊到清晰的变化过程则表明油面下降,判定注油孔畅通;若光斑无变化则表明油面没有下降,判定注油孔堵塞。
为了更好地实现本发明,步骤(2)中的光源设置在注油孔的正上方。
本发明与现有技术相比,具有以下优点及有益效果:
本发明的步骤简单,便于操作,还能自动检测压缩机的注油孔是否畅通,从而能避免人工检测所造成的检测失误,因此能保证检测的准确率,还能节约人力资源。
具体实施方式
下面结合实施例对本发明作进一步地详细说明,但本发明的实施方式不限于此。
实施例
本发明的压缩机注油检测方法,主要是将油注入注油孔中,然后根据油面在注油孔中的变化情况判定注油孔是否畅通。实施时,将本发明的方法使用在生产线上,当压缩机通过生产线流动到注油检测工位,首先通过工位上设置的油枪向压缩机注油孔中注油。在重力作用下,注油孔中的油面将下降。然后使用光源同轴照射油孔,实施时,将光源设置在注油孔的正上方,可方便垂直照射注油孔。
然后使用拍摄设备拍摄注油孔中油面下降的图像,并根据拍摄到油面下降的图像判定注油孔是否畅通。本发明使用的拍摄设备为数码拍摄设备,该数码拍摄设备可以是数码相机,也可以是数码摄像机,还可以是其他数码拍摄设备,本实施例中使用的是数码相机。具体的,在油被注入注油孔中后,由于油和金属浸润,油面在注油孔中呈凹面,该凹面对同轴光反射聚焦,并在拍摄的图像上形成光斑。随着油面的下降,反射光交点即光斑也同时下降,由于数码相机的景深限制,反射光交点会在数码相机的焦平面上呈现最清晰的光斑。油面下降过程中,拍摄的图像上的光斑会出现由模糊到清晰再到模糊的变化过程,如果油面没有下降,则拍摄的图像上的光斑不会变化。若光斑呈现出由模糊到清晰的变化过程则表面油面下降,则可判定注油孔畅通;若光斑无变化则表面油面没有下降,则可判定注油孔堵塞。
本发明中使用的光源和拍摄设备均可固定设置在生产线的注油检测工位上,在完成压缩机的注油检测工序后,压缩机通过生产线上的传送带送入下一工序,生产线的传送带则向注油检测工位送入另一台压缩机进行检测。本发明通过光源照射注油孔中的油面并使油面在数码相机拍摄的图像上形成光斑的方式可自动检测注油孔中的油面是否变化,据此则可判定注油孔是否畅通,从而能准确的检测出压缩机的注油孔是否合格,因此能保证检测的准确率,还能节约人力资源。
如上所述,便可较好的实现本发明。
