Description

  The present invention relates to a component cleaning jig used when, for example, cleaning a relatively small small component such as a fingertip, and in particular, immersed in a cleaning liquid filled in a cleaning tank in a state where a plurality of components to be cleaned are accommodated. The present invention also relates to a component cleaning jig for cleaning a component to be cleaned by ultrasonic vibration.

  For example, as a method of cleaning a plurality of small parts used for electronic devices at a time, ultrasonic cleaning is performed by immersing these small parts (parts to be cleaned) in a cleaning liquid and applying ultrasonic vibration. It is suitably performed (see, for example, Patent Document 1). In this ultrasonic cleaning, the parts to be cleaned are accommodated in a cleaning basket made of a metal mesh or the like, and the parts to be cleaned are immersed in a cleaning tank filled with a cleaning solution together with the cleaning basket, and cavitation is generated by ultrasonic vibration. The parts to be cleaned in the cleaning basket were cleaned using the impact of this cavitation.

JP 2001-017929 A

  By the way, when cleaning is performed without fixing a plurality of small parts in the cleaning tub by such a method, the parts may overlap in the cleaning tub. If the components overlap in this way, there is a problem that the cleaning efficiency of the overlapped portion is reduced. In addition, when ultrasonic cleaning is performed in a state where the components are overlapped with each other, a contact portion between the components may be damaged by vibration.

  The present invention has been made in view of the above circumstances, and provides a component cleaning jig capable of efficiently cleaning by preventing overlapping of components when ultrasonically cleaning a plurality of components to be cleaned. The purpose is that.

The present invention has been proposed in order to achieve the above-described object. The vibration source is immersed in a cleaning liquid filled in a cleaning tank in a state where a plurality of parts to be cleaned are accommodated, and is provided in the cleaning tank. A component cleaning jig for cleaning the component to be cleaned by ultrasonic vibration of
A base member and a cover member laminated on the component placement surface side of the base member;
In the state where the base member and the cover member are stacked, an individual holding part capable of individually holding each object to be cleaned and a liquid passage for passing the cleaning liquid to each individual holding part side are formed. It is characterized by.

  According to the above configuration, the plurality of parts to be cleaned are individually held without contacting or overlapping each other, and the cleaning liquid is sufficiently distributed to the individual holding part side through the liquid passage. It is possible to efficiently remove dirt adhering to the surface. That is, it is possible to spread cavitation in ultrasonic cleaning to every corner of the component to be cleaned, and to more reliably remove and remove dirt such as oil adhering to the component to be cleaned by the impact of the cavitation.

  In the above-described configuration, it is desirable that a component support portion capable of supporting the component to be cleaned at at least three contact points is formed on each of the individual holding portions of the base member and the cover member.

  According to this configuration, since the component to be cleaned is supported by the component support portion with the smallest possible contact point, the cleaning liquid such as pure water can be more evenly distributed to the component to be cleaned. As a result, the cleaning effect can be enhanced.

  Moreover, in the said structure, it is desirable for the individual holding | maintenance part of a base member and the said cover member to penetrate the plate | board thickness direction of each of these members, and to form the liquid penetration hole.

  According to this configuration, since the cleaning liquid can be passed through the liquid holding hole to the individual holding part side, or the air (bubbles) of the individual holding part can be discharged through the liquid hole, the cleaning efficiency is further improved. be able to.

In the above configuration, an accommodation recess capable of accommodating the component to be cleaned is formed in one of the base member or the cover member, and the other is inserted into a hollow portion of the component to be cleaned in a state of being accommodated in the accommodation recess. Project the insertion boss to be
The individual holding portion is constituted by the housing recess and the insertion boss,
It is also possible to adopt a configuration in which the dimension of the insertion boss is set so that the insertion boss is filled in the hollow portion in a state where the insertion boss is inserted into the hollow portion of the component to be cleaned.

  According to this configuration, when cleaning a component to be cleaned having a hollow portion, the insertion boss fills the hollow portion of the component to be cleaned, so that air bubbles can be prevented from staying in the hollow portion. It is possible to prevent the cleaning efficiency on the hollow part side of the part to be cleaned from being lowered.

  In the above configuration, it is desirable that the housing recess is formed so as to penetrate the thickness direction of the one member.

  According to this configuration, the cleaning liquid can be passed through the storage recesses to the individual holding unit side, and the air (bubbles) of the individual holding units can be discharged through the storage recesses, so that the cleaning efficiency can be further improved. it can.

Further, in the above configuration, at least one of the base member or the cover member is provided with a contact protrusion protruding toward the other member side in the stacked state of both members,
It is desirable to adopt a configuration in which a gap functioning as the liquid passage is formed between the base member and the cover member by the contact protrusion contacting the other member in a laminated state of both members.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. In the embodiments described below, various limitations are made as preferred specific examples of the present invention. However, the scope of the present invention is not limited to the following description unless otherwise specified. However, the present invention is not limited to these embodiments.

  First, based on FIG. 1, the valve body 1 as a kind of parts to be cleaned in the present invention will be described. 1A and 1B are diagrams for explaining the configuration of the valve body 1 in the present embodiment. FIG. 1A is a cross-sectional view of the valve body 1 and FIG. 1B is a plan view of the valve body 1. The illustrated valve body 1 is a component used in a liquid ejecting apparatus such as an ink jet recording apparatus (printer). The printer has a configuration in which an ink cartridge storing ink is arranged on the printer main body side, and pressure is supplied from the ink cartridge to the recording head (a kind of liquid ejecting head) by pressurizing the inside of the ink cartridge ( There is a so-called off-carriage type. In this configuration, when the pressure of the ink pumped to the recording head side fluctuates, the amount of ink droplets ejected from the recording head becomes non-uniform, and the image quality of the recorded image may be degraded. For this reason, a printer employing an off-carriage configuration includes an adjustment valve (pressure reducing valve) so as to adjust the supply pressure of ink supplied to the recording head. The illustrated valve body 1 is used for this adjustment valve, and is about the size of the tip of a little finger (see, for example, JP-A-2005-343123 (FIG. 3)).

  The valve body 1 in the present embodiment is formed in a substantially top-piece shape from a shaft portion 2 and a flange portion 3 extending laterally from the shaft portion 2, and is made of, for example, a modified polyphenylene ether resin. ing. An elastic body 4 (so-called packing) produced in a substantially donut shape following the shape of the flange portion 3 is formed on one surface (the upper surface in FIG. 1A) of the flange portion 3 of the valve body 1. It is attached (hatched portion in FIG. 1B). The elastic body 4 is made of, for example, an elastomer and has a contact portion 5 for closing the ink flow path in a liquid-tight state when the valve body 1 actually functions as an adjustment valve.

  Since the valve body 1 having the above-described configuration is disposed in an ink flow path through which ink passes, it is necessary to remove dirt such as oil and dust on the surface of the valve body 1 as much as possible before assembly to the printer. In order to remove the dirt, ultrasonic cleaning is preferably performed in which ultrasonic vibration is applied while being immersed in the cleaning liquid. Conventionally, when performing this ultrasonic cleaning, in order to clean more valve bodies 1 at a time, a plurality of valve bodies 1 are accommodated in a cleaning tub and the entire cleaning tub is immersed in a cleaning solution for cleaning. . However, when cleaning is performed in a state where each valve body 1 is housed in the cleaning tub without being fixed as it is, the valve bodies may overlap in the cleaning tub. If the valve bodies overlap with each other in this way, it becomes difficult to clean evenly. In addition, when ultrasonic cleaning is performed in a state where the valve bodies are overlapped with each other, there is a possibility that the contact portion between the parts is damaged by vibration.

The component cleaning jig according to the present invention has been proposed in view of the above-described problems, and is configured so that a plurality of valve bodies 1 can be cleaned evenly.
FIG. 2 is a cross-sectional view illustrating a configuration of the component cleaning jig, and FIG. 3 is a cross-sectional view of a main part around an individual holding unit in the component cleaning jig. The component cleaning jig 7 in the present embodiment includes a base member 8 and a cover member 9 laminated on the component placement surface side of the base member 8. These members are made, for example, from a synthetic resin in a rectangular tray shape in a plan view, and in a stacked state, the individual holding portions 10 that can individually hold a plurality of valve bodies 1 and the individual holding portions 10 side. A liquid passage 11 for passing the cleaning liquid is formed.

  As shown in FIG. 4, a plurality of base side holding portions 13 for holding the valve body 1 are formed on the component arrangement surface of the base member 8. The base-side holding portion 13 has a shaft housing portion 14 formed of a through hole having a rectangular opening shape, and a bowl-like shape projecting from the inner wall surfaces of four sides defining the shaft housing portion 14 toward the center side of the hole. The holding island portion 15 is a portion that functions as an individual holding portion 10 that holds one valve element 1 together with a cover-side holding portion 17 of a cover member 9 described later.

  The shaft accommodating portion 14 has an inner dimension (interval between opposing inner wall surfaces) set to be slightly larger than the diameter of the flange portion 3 of the valve body 1. The shaft portion 2 of the valve body 1 is inserted into a portion surrounded by the holding island portion 15. Further, the shaft accommodating portion 14 also functions as a liquid passage hole for allowing the cleaning liquid in the cleaning tank to pass through the individual holding portion 10 during the cleaning and for discharging the bubbles of the individual holding portion 10 to the outside. . As shown in FIG. 3, the holding island portion 15 is provided in a state where it is retreated by one step from the component placement surface toward the opposite bottom surface side. The holding island portion 15 is a portion that supports the flange portion 3 when the valve body 1 is held by the individual holding portion 10, and functions as a component support portion in the present invention. Moreover, the ridge corner part of the flange part support surface periphery in this holding island part 15 is chamfered, and the contact area with respect to the flange part 3 becomes small as much as possible. Further, the distance between the holding island portions facing each other (the distance between the two end faces) is set slightly larger than the maximum diameter of the shaft portion 2 and smaller than the diameter of the flange portion 3.

  The gap of the step between the component placement surface and the holding island portion 15 is set to be slightly larger than the total thickness of the flange portion 3 and the elastic body 4, and as shown in FIG. It is comprised so that the valve body 1 may be hold | maintained by the part 3 fitting. In the present embodiment, an example in which the shaft accommodating portion 14 is configured with a rectangular hole in plan view has been described. However, the present invention is not limited thereto, and the shaft accommodating portion 14 may be configured with a through hole having another shape such as a circular shape in plan view. good. Moreover, regarding the holding island part 15, in this embodiment, although the structure provided with four with respect to one individual holding part 10 was illustrated, it is not restricted to this, What is necessary is just a structure provided with at least 3 or more.

  As shown in FIG. 5, a plurality of cover side holding portions 17 are formed corresponding to the base side holding portions 13 on the covering surface of the cover member 9 which is a surface facing the component arrangement surface of the base member 8. The cover-side holding portion 17 includes a shaft insertion portion 18 formed of a circular through hole, a plurality of protrusions 19 arranged so as to surround the periphery of the shaft insertion portion 18, and an outer side of the protrusion portion 19. It is comprised from the circular arc-shaped through-opening part 20 arrange | positioned. The shaft insertion portion 18 is a portion through which the shaft portion 2 is inserted when the valve body 1 is held by the individual holding portion 10, and has an inner diameter slightly larger than the maximum diameter of the shaft portion 2. The shaft insertion portion 18 also functions as a liquid passage hole in the same manner as the shaft housing portion 14 described above. Further, the through opening 20 is also a through hole that functions as a liquid passage hole, and is provided for each cover side holding portion 17 in two with the shaft insertion portion 18 and the protrusion 19 interposed therebetween. . Of course, the shape and number of the through openings 20 are not limited to those illustrated.

  As shown in FIG. 3, the protruding portion 19 is provided so as to protrude from the covering surface of the cover member 9 toward the component placement surface side of the base member 8, and the base member 8 and the cover member 9 are laminated. The dimensions are set such that the tip of the protrusion 19 is positioned slightly in front of the elastic body 4 of the valve body 1 (the covering surface side) in the posture with the base member 8 facing down. Further, the elastic body 4 of the valve body 1 is supported by the projection 19 in the inverted posture with the cover member 9 on the lower side. That is, the protruding portion 19 functions as a component support portion similarly to the holding island portion 15. In the present embodiment, a total of four protrusions 19 are disposed in a state where the phase of the arrangement position between the adjacent protrusions 19 is shifted by 90 degrees. And the projection part 19 is exhibiting hemispherical shape, and the contact area with respect to the elastic body 4 of the valve body 1 becomes small as much as possible. The protrusion 19 is not limited to a hemispherical shape, and any shape can be adopted, and a shape that can be supported by point contact with the elastic body 4 is desirable. Further, the number of the protrusions 19 is not limited to four, but may be a configuration in which at least three or more are provided.

  As shown in FIG. 6, the cover member 9 in the present embodiment extends a hook portion 22 from the covering surface toward the component placement surface side of the base member 8 in the stacked state. One hook portion 22 is disposed at each of the four corners of the cover surface of the cover member 9, and a locking claw 23 projects laterally at the tip portion. Further, in the base member 8, insertion portions 24 into which the hook portions 22 can be inserted are opened at positions corresponding to the hook portions 22 of the cover member 9 in a state of penetrating the plate thickness direction. In the insertion portion 24, a locked portion 25 for protruding the locking claw 23 in a state in which the hook portion 22 is inserted into the insertion portion 24 is protruded from the opening edge portion on the component placement surface side. . Further, in the vicinity of the fitting portion 24 in the base member 8, an abutting protrusion 26 protrudes toward the cover surface side of the cover member 9. The contact protrusion 26 forms a gap between the base member 8 and the cover member 9 to such an extent that the valve body 1 held by the individual holder 10 does not detach regardless of the posture of the component cleaning jig 7. Set to dimensions. The gap functions as the liquid passage 11.

  When cleaning the valve body 1 using the component cleaning jig 7 configured in this way, first, the valve body 1 is set to each base side holding portion 13 of the base member 8 one by one. Next, the cover member 9 is stacked on the base member 8 with the covering surface facing the component placement surface. At this time, by inserting the hook portion 22 into the insertion portion 24, the position of the cover member 9 in the surface direction with respect to the base member 8 is defined, and the valve body 1 is formed by each base side holding portion 13 and each cover side holding portion 17. Will be sandwiched. When the hook portion 22 is pushed further into the insertion portion 24, the contact protrusion 26 of the base member 8 contacts the covering surface of the cover member 9 and the locking claw 23 is locked to the locked portion 25. Thereby, the base member 8 is fixed to the cover member 9 in a state where the liquid passage 11 is formed between the base member 8 and the cover member 9, and the valve body 1 is held by the individual holding portion 10.

  Next, as shown in FIG. 7, a plurality of component cleaning jigs 7 holding the valve body 1 are stacked, and the stacked body is accommodated in a cleaning basket 29. The cleaning basket 29 is formed of, for example, a metal mesh-like box, and the inside thereof is an accommodation space that accommodates the laminated body of the component cleaning jig 7. One of the six wall surfaces constituting the cleaning bowl 29 is a lid 29 'that can be opened and closed. By opening the lid 29', the laminate can be accommodated in the accommodation space. . Further, since the cleaning tub 29 has a mesh shape, the cleaning liquid is filled into the housing empty space through the mesh hole even during the cleaning even when the lid 29 'is closed. In addition, although the attitude | position of the components washing jig 7 at the time of accommodating the laminated body of the components washing jig 7 in the washing bowl 29 is arbitrary, in this embodiment, as shown in FIG. On the other hand, each component cleaning jig 7 is housed in the cleaning tub 29 in an upright posture.

  Then, the cleaning tub 29 containing the laminated body of the component cleaning jig 7 is put into the cleaning tank 30 filled with the cleaning liquid 31. At this time, the cleaning tub 29 is immersed in the cleaning liquid while being held by the holding arm 32. An ultrasonic vibration source 32 (a kind of vibration source in the present invention) is disposed at the bottom of the cleaning tank 30. The ultrasonic vibration source 32 includes an ultrasonic vibrator and an ultrasonic oscillator. As the cleaning liquid 31, for example, an alkaline solution such as KOH or pure water can be used. In the present embodiment, the cleaning process for the valve body 1 is performed using a total of five cleaning tanks. In the first tank, ultrasonic cleaning is performed using a cleaning tank 30 filled with a cleaning liquid 31 made of an alkaline solution, and dirt adhering to the valve body 1 is cleaned. In the second and subsequent tanks, an alkaline solution attached to the component cleaning jig 7 is washed away using a cleaning tank filled with pure water (warm water) as a cleaning liquid.

  When the cleaning bowl 29 containing the laminated body of the component cleaning jig 7 is immersed in a cleaning liquid such as pure water, the cleaning liquid and the like are passed through the individual holding portions 10 through the liquid passages 11. Further, the air (bubbles) of each individual holding unit 10 is discharged to the outside through the liquid passage 11. Further, in the present embodiment, in addition to the liquid passage 11, a liquid passage hole such as the shaft housing part 14 or the shaft insertion part 18 is provided, so that the cleaning liquid can be passed to the individual holding part side through the liquid passage hole. The air (bubbles) in the individual holding part can be discharged through the liquid hole. Thereby, the cleaning efficiency can be further improved. Further, in the present embodiment, each individual holding unit is provided to immerse the component cleaning jig 7 in the cleaning liquid in such a posture that the liquid passage 11 extends in the vertical direction with respect to the bottom of the cleaning tank. 10 bubbles can be easily discharged through the liquid passage 11 by buoyancy.

  When washing in each tank is completed, the process proceeds to the drying process. In this drying step, the laminated body of the component cleaning jig 7 is taken out from the cleaning basket 29, and the residual liquid is removed by centrifugal force by setting the laminated body in a spin dryer and rotating at high speed. Also in this drying process, since each valve body 1 is hold | maintained individually, without overlapping, it can dry efficiently. Further, when the next process is performed after drying, since the valve bodies 1 are held in the component cleaning jig 7 in an aligned state, the work efficiency can be improved.

  As described above, the component cleaning jig 7 according to the present invention individually holds the plurality of valve bodies 1 in the individual holding unit 10 in a fixed posture without contacting or overlapping each other, and through the liquid passage 11 or the like. Since the cleaning liquid or the like is sufficiently distributed to each individual holding unit 10, it is possible to efficiently remove dirt adhering to the surface of the valve body 1. That is, cavitation in ultrasonic cleaning can be spread to every corner of the valve body 1, and dirt such as oil adhering to the valve body 1 can be more reliably peeled and removed by the impact of the cavitation. Further, since the valve body 1 held by the individual holding part 10 is supported at a contact point as small as possible by the component support parts such as the holding island part 15 and the protruding part 19, The cleaning liquid can be distributed more evenly. As a result, cleaning can be performed more efficiently.

  By the way, the present invention is not limited to the above-described embodiment, and various modifications can be made based on the description of the scope of claims.

For example, in the above embodiment, the valve body 1 is exemplified as the component to be cleaned. However, the present invention is not limited to this, and the component cleaning jig according to the present invention is suitable for cleaning various components to be cleaned.
In the second embodiment shown in FIG. 9, a component cleaning jig 7 ′ configured to hold a coil spring 36 as a component to be cleaned is illustrated. FIG. 9 is an essential part cross-sectional view showing an enlarged peripheral part of the individual holding part 37.

  The component cleaning jig 7 'in the present embodiment is composed of a base member 8' and a cover member 9 ', and the configuration other than the individual holding portion 37 is the same as that of the component cleaning jig 7 in the first embodiment. It has a configuration. The coil spring 36 held by the individual holding portion 37 is a deformed coil spring formed so that its diameter gradually increases from one side (upper side in the figure) to the other side (lower side in the figure).

  The individual holding part 37 includes an accommodation recess 38 and an insertion boss 39. In the illustrated configuration, the accommodation recess 38 is formed in the cover member 9 ′, and the insertion boss 39 is formed in the base member 8 ′. It is also possible to adopt a configuration in which the housing recess 38 is formed in the base member 8 'while the insertion boss 39 is formed in the cover member 9'. The accommodating recess 38 is a cylindrical hollow portion set to a size capable of accommodating most of the coil spring 36, and follows the outer shape of the coil spring 36 and the upper surface of the cover member 9 ′ (surface opposite to the covering surface). The shape gradually increases in diameter toward the coating surface side. In addition, the housing recess 38 in the present embodiment is formed so as to penetrate through the thickness direction of the cover member 9 ′, and allows cleaning liquid or pure water to pass through the individual holding part 37 side during cleaning, or the individual holding part The air bubbles on the 37 side can be discharged to the outside.

  The insertion boss 39 is a portion to be inserted into the hollow portion of the coil spring 36 held by the individual holding portion 37, and follows the shape of the hollow portion from the base end side (the component placement surface side of the base member 8 ′). It has a cylindrical shape that gradually becomes thinner toward the tip side. Further, as shown in the figure, the insertion boss 39 is dimensioned so as to fill the hollow portion when the coil spring 36 is inserted into the hollow portion.

  In the component cleaning jig 7 ′ in this embodiment, when the cover member 9 ′ is stacked on the base member 8 ′ with the coil spring 36 held on the individual holding portion 37, the component cleaning treatment shown in the first embodiment is performed. Similarly to the tool 7, a liquid passage 11 ′ is formed between the base member 8 ′ and the cover member 9 ′, and a gap G is formed between the coil spring 36 and the inner wall surface of the housing recess 38. It has become. The gap G is set to such a size that the coil spring 36 is not detached from the individual holding portion 37 regardless of the posture of the component cleaning jig 7 ′. And this gap | interval G is provided so that a washing | cleaning liquid and a pure water may enter during washing | cleaning.

  When cleaning the coil spring 36 as described above, conventionally, air remains in the hollow portion, and the cleaning efficiency inside the spring may be reduced. On the other hand, when the coil spring 36 is cleaned using the component cleaning jig 7 ′ of the present embodiment, the insertion boss 39 is filled in the hollow portion of the coil spring 36, thereby preventing bubbles from staying in the hollow portion. This makes it possible to prevent a reduction in cleaning efficiency inside the spring.
