Description

  The present invention relates to a method and apparatus for cleaning an object to be cleaned particularly for removing fine particles.

JP, 2005-349380, A Conventionally, as shown in patent documents 1, the work frame was fixedly arranged inside the washing tub or the outside of the washing tub, and the storage frame in which the object to be cleaned was stored on the work pedestal. A cleaning apparatus that cleans an object to be cleaned by arranging the above is already known. The cleaning device is provided with a purification mechanism, and the object to be cleaned in the storage frame is cleaned with the cleaning liquid cleaned by the purification mechanism.

  However, when a work table is fixedly arranged inside or outside the cleaning tank as shown in Patent Document 1, liquid cleaning must be performed within a limited range on the fixed work table. Therefore, since it is difficult to perform liquid cleaning by immersing an object to be cleaned in a cleaning liquid stored in a large amount in a cleaning tank as in the past, the cleaning effect may occur because the dirt may not be sufficiently removed. Was a concern.

  Accordingly, the present invention is intended to solve the above-described problems, and can sufficiently perform liquid cleaning with the cleaning liquid stored in the cleaning tank, and reliably removes dirt adhering to the object to be cleaned. An object of the present invention is to obtain a cleaning method and apparatus for an object to be cleaned that can improve the cleaning efficiency as possible.

  In order to solve the problems as described above, the first invention of the present application arranges a mounting table that can be moved up and down by a vertical movement mechanism in a cleaning tank in which a cleaning liquid is housed, and mounts an object to be cleaned on the mounting table. At the same time, the cleaning liquid in the cleaning tank is brought into contact with the object to be cleaned to perform pretreatment cleaning of the object to be cleaned, and then the mounting table is exposed from the surface of the cleaning liquid, and the surface of the mounting table is cleaned. A cylindrical storage frame surrounding the outer periphery of the object is disposed so that the lower end surface of the storage frame is in close contact with the surface of the mounting table, and the cleaning liquid in the cleaning tank is purified by a purification mechanism communicating with the cleaning tank. The cleaned cleaning liquid is stored in the storage frame and brought into contact with the object to be cleaned in the storage frame, whereby the object to be cleaned is finished in the storage frame.

  In the second invention of the present application, a mounting table that can be moved up and down by a vertical movement mechanism is arranged in a cleaning tank containing cleaning liquid therein, and an object to be cleaned is mounted on the mounting table, and the object to be cleaned is placed in the cleaning tank. The pretreatment cleaning of the object to be cleaned is performed by immersing in the cleaning liquid, and then the cleaning liquid in the cleaning tank is placed in a cylindrical storage frame placed on a mounting table so as to surround the outer periphery of the object to be cleaned. In the housed state, the mounting table is exposed from the surface of the cleaning liquid in the cleaning tank, and the cleaning liquid in the storage frame is discharged from the gap provided between the surface of the mounting table and the storage frame, and the cleaning is performed. The cleaning liquid in the cleaning tank is purified by a purification mechanism communicating with the tank, and the purified cleaning liquid is put into the storage frame, and the amount of the cleaned cleaning liquid charged into the storage frame is discharged from the storage frame. The cleaning liquid stored in this storage frame is covered with By contacting the Kiyoshibutsu performs a finishing cleaning of the object to be cleaned while circulating the washing liquid in storage frame within.

  In the first and second inventions of the present application, as described above, after the object to be cleaned is immersed in the cleaning liquid to perform pretreatment cleaning of the object to be cleaned, the cleaned cleaning liquid is stored in the storage frame and stored in the storage frame. Since the object to be cleaned is finished and cleaned in the storage frame by contacting the object to be cleaned in the storage frame, after removing rough dirt adhering to the object to be cleaned in the pretreatment cleaning, Fine dirt that could not be removed by the pretreatment cleaning can be removed.

  In this way, the object to be cleaned can be directly immersed in the cleaning liquid stored in the cleaning tank, so that even if a large amount of dirt adheres to the object to be cleaned, pre-cleaning is sufficient. Dirt can be effectively removed with an appropriate amount of cleaning liquid. In addition, since the cleaning liquid purified by the purification mechanism is used at the time of final cleaning, there is little possibility that dirt will reattach, and even fine dirt can be reliably removed. Therefore, the dirt adhering to the object to be cleaned can be surely removed by the pretreatment cleaning and the finish cleaning, so that the liquid cleaning can be performed efficiently.

  The third invention of the present application is a cleaning apparatus for an object to be cleaned for performing the method for cleaning an object to be cleaned according to the first and second inventions, a cleaning tank containing a cleaning liquid therein, A mounting table that is located inside and can be moved up and down by a vertical movement mechanism, a cylindrical storage frame that is disposed on the mounting table and that can store an object to be cleaned, and is passed through the cleaning tank. A cleaning mechanism that can clean the used cleaning liquid in the cleaning tank.In the pre-processing cleaning, the cleaning object is cleaned with the cleaning liquid in the cleaning tank, and In the storage frame on the mounting table, the cleaning mechanism purifies by the cleaning mechanism and finish cleaning with the cleaning liquid stored in the storage frame.

  As described above, since the pretreatment cleaning and the finish cleaning can be performed in one cleaning tank, the apparatus can be made compact and the manufacturing cost can be reduced. Further, by providing the purification mechanism, the cleaning liquid can be purified and reused, and the cleaning cost can be reduced by reducing the consumption of the cleaning liquid.

  Further, the storage frame may be provided separately from the mounting table, or may be provided integrally with the mounting table.

  Further, the object to be cleaned may be swingable and / or rotatable by a vertical movement mechanism and / or a rotation mechanism provided on the mounting table. By making the object to be cleaned swingable and / or rotatable in this way, an external force can be applied to the object to be cleaned during liquid cleaning, and the cleaning effect can be enhanced.

  Further, the pretreatment cleaning and the finish cleaning may be performed under normal pressure or reduced pressure.

  The storage frame may be arranged so that a gap is formed between the storage frame and the mounting table. By forming the gap in this way, when the cleaning liquid is stored in the storage frame, the cleaned cleaning liquid can be discharged from the gap together with the dirt. For this reason, the amount of the cleaned cleaning liquid introduced into the storage frame is made larger than the amount of the cleaning liquid discharged from the storage frame, and the cleaned cleaning liquid is stored in the storage frame and brought into contact with the object to be cleaned. Since the object to be cleaned can be finished and cleaned while the cleaning liquid is circulated inside and replaced with a new one purified by the cleaning liquid, the cleaning effect of the object to be cleaned can be further enhanced.

  The storage frame may be arranged so as to be in close contact with the mounting table.

  In addition, the purification mechanism has a discharge pipe that can discharge the cleaning liquid inside the cleaning tank, a filter that can clean the cleaning liquid from the discharge pipe, and an introduction that introduces the cleaning liquid purified by this filter into the cleaning tank again. It may be provided with a tube.

  In the present invention, as described above, after the object to be cleaned is immersed in the cleaning liquid to perform the pretreatment cleaning of the object to be cleaned, the cleaned cleaning liquid is stored in the storage frame and is stored in the cleaning object in the storage frame. Since the object to be cleaned is finished and cleaned in this storage frame by bringing it into contact, after removing rough dirt adhering to the object to be cleaned in the pretreatment cleaning, it is removed by the above pretreatment cleaning with the cleaning liquid. It becomes possible to remove fine dirt that could not be removed.

  In this way, the object to be cleaned can be directly immersed in the cleaning liquid stored in the cleaning tank, so that even if a large amount of dirt adheres to the object to be cleaned, pre-cleaning is sufficient. Dirt can be effectively removed with an appropriate amount of cleaning liquid. In addition, since the cleaning liquid purified by the purification mechanism is used at the time of final cleaning, there is little possibility that dirt will reattach, and even fine dirt can be reliably removed. Therefore, the dirt adhering to the object to be cleaned can be surely removed by the pretreatment cleaning and the finish cleaning, so that the liquid cleaning can be performed efficiently.

  In addition, since the pretreatment cleaning and the finishing cleaning can be performed in one cleaning tank, a compact apparatus can be obtained and the manufacturing cost can be reduced. Further, by providing the purification mechanism, the cleaning liquid can be purified and reused, and the cleaning cost can be reduced by reducing the consumption of the cleaning liquid.

Therefore, the cleaning effect at the time of pretreatment cleaning can be enhanced. At this time, since the ultrasonic cleaning can be performed by operating the ultrasonic vibrator (103) provided at the bottom (94) of the cleaning tank (84), the cleaning effect can be further enhanced.

  After the pretreatment cleaning as described above, the finish cleaning is performed. The finish cleaning will be described. First, as shown in FIG. 8, the vertical movement mechanism (86) is operated to place the mounting table (82) above the liquid surface (104) of the cleaning liquid (85). At this time, the height of the mounting table (82) is adjusted in advance so that the ejection head (101) is positioned above the storage frame (80). Next, the pump (95) provided in the discharge pipe (96) is operated to discharge the cleaning liquid (85) used in the pretreatment cleaning from the cleaning tank (84) to the discharge pipe (96) and the discharge pipe (96 The cleaning liquid (85) discharged to the filter is purified by the filter (100) of the purification mechanism (102). The purified cleaning liquid (85) is sprayed from the spray head (101) into the cleaning tank (84) through the introduction pipe (98).

  Here, the storage frame (80) and the mounting table (82) are integrally formed and a flow hole (81) is formed between the lower end surface (81) of the storage frame (80) and the surface (83) of the mounting table (82). 92) is provided, the cleaning liquid in the storage frame (80) is discharged from the flow hole (92). Therefore, the cleaning liquid (85) in the storage frame (80) is injected in an amount larger than the discharge amount of the cleaning liquid (85) from the flow hole (92), so that the cleaning liquid (85) is discharged into the storage frame (80). (85) will be stored. Accordingly, the object to be cleaned (93) can be subjected to immersion cleaning with the cleaning liquid (85) stored in the storage frame (80).

  At the time of this final cleaning, the used cleaning liquid (85) located on the bottom side of the storage frame (80) is discharged from the flow hole (92) together with dirt. In this way, the purified cleaning liquid (85) is ejected from the ejection head (101) into the storage frame (80), and the used cleaning liquid (85) is discharged together with dirt from the bottom side of the storage frame (80). Accordingly, since the cleaning liquid (85) in the storage frame (80) circulates, the cleaning effect of the final cleaning can be enhanced, and the particle removal effect can be improved. After the dirt from the object to be cleaned (93) is removed, the cleaning liquid (85) in the storage frame (80) is completely removed by stopping the injection of the cleaning liquid (85) from the injection head (101). Is discharged to the outside and finish cleaning is finished.
