Until now, cover glasses for smartphones have been planar, but in recent years, the use of 3D glass has increased in terms of design and function. In addition to cover glass for smartphones, glass other than planar glass such as 3D glass is increasingly used for various products such as glass used for in-vehicle displays and PC displays.

3D glass refers to glass that has a flat portion and a curved portion that rises from the edge of the flat portion, as shown in FIG. 11, for example. It is not difficult to automatically clean the surface of the 3D glass with a cleaning device that sprays water or a cleaning liquid. However, in the case of the type that sprays water or a cleaning solution, there are cases where marks of blowing remain on the surface of the glass after cleaning. Since it is difficult to use cleaning that leaves blow marks in the cleaning just before assembly to the product, the type of cleaning by rubbing with a cloth or the like is preferred. However, since the curved surface portion of the 3D glass cannot be automatically cleaned with the type of device that wipes off the surface with a cloth or the like, it has been necessary to manually perform the cleaning work.

(Configuration of cleaning device 10)
A configuration according to an embodiment of a cleaning device 10 to which the present invention is applied will be described with reference to the drawings. In the following description, the same parts are given the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

The types of glass used in smartphones and the like include flat glass, circular glass, 2.5D glass that is ground so that the edges of the upper surface of flat glass are rounded, and flat glass. There is 3D glass or the like formed by bending both ends in the width direction in a heated state. The cleaning device 10 according to this embodiment is used to clean both sides of, for example, 3D glass G as an object to be cleaned. Of course, not only the 3D glass G, but also the above-described flat glass, circular glass, 2.5D glass ground so as to round the edges of the upper surface of the flat glass, and the like are objects to be cleaned. good too.

In this specification, the surface of the 3D glass G on which both ends in the curved width direction extend (the surface opposite to the side exposed when attached to the smartphone) is referred to as the “lower surface”. The surface on the opposite side of the “lower surface” (the surface that is exposed when attached to the smartphone) is called the “upper surface”.

As shown in FIG. 1 , the cleaning device 10 according to this embodiment generally includes a cleaning section 12 , a reversing mechanism 14 and a second cleaning section 16 . The direction from the cleaning section 12 to the second cleaning section 16 is called "first direction X", and the opposite direction is called "second direction Y".

The cleaning section 12 cleans the lower surface of the 3D glass G, and as shown in FIG.

The conveying unit 20 holds and conveys the uncleaned 3D glass G, and includes a holder 24 that holds the 3D glass G and a holder moving mechanism that moves the holder 24 mainly in the first direction X. 26.

The holding base 24 holds the 3D glass G with its lower surface facing upward. Therefore, as shown in FIG. 3, the upper surface of the holding table 24 is formed with a groove 28 into which the upper surface of the 3D glass G is fitted. When the 3D glass G, which is an object to be cleaned, is fitted into the groove 28 formed in the holding table 24, the 3D glass G is restricted from moving in directions other than upward.

Returning to FIG. 2, the holding table moving mechanism 26 is a mechanism for moving the holding table 24 in the first direction X as described above. Although not shown, the holder moving mechanism 26 includes a motor for generating power to be transmitted to the holder 24 and a guide member along the first direction X (and the second direction Y).

Returning to FIG. 1, the cleaning unit 22 comes into contact with the lower surface of the 3D glass G conveyed by the conveying unit 20 to wipe and clean the surface. 32 , a cleaning liquid supply device 34 , a head driving mechanism 36 and a pressing member 38 .

The cleaning head 30 is composed of a base 50 and a wiping member 52, as shown in FIG.

The base 50 is a member made of a material (for example, resin) that is relatively harder than the wiping member 52. Inside the base 50, a fluid (for example, , liquid, air or other gas) to the wiping member 52 is provided. For example, one end 56 of the fluid supply channel 54 is formed on the top surface of the base 50 and the other end 58 is formed on the side surface of the base 50 . The other end 58 of the fluid supply path 54 is formed at a position communicating with a fluid intake hole 60 formed in the wiping member 52 .

A fitting groove 62 into which the wiping member 52 is fitted is formed in the lower surface of the base 50 . In the cleaning head 30 according to this embodiment, two circular tube-shaped wiping members 52 are used, so two fitting grooves 62 are also formed. Of course, the shape of the fitting groove 62 is not limited to this, as long as it matches the shape of the wiping member 52 .

The wiping member 52 is a relatively soft elastic material (especially the side surface in the direction orthogonal to the first direction X) arranged from the lower surface of the base 50 to the side surface (especially the side surface in the direction orthogonal to the first direction X). It is a member formed of, for example, an elastic body such as rubber or silicon) whose outer dimensions of 52 change. The wiping member 52 according to this embodiment is formed in the shape of a circular tube in cross section as described above, and the fluid intake holes 60 formed at both ends of the wiping member 52 are formed in the side surfaces of the base 50, respectively. It is connected to the other end 58 . Also, in this embodiment, two wiping members 52 are used, each fitted in a fitting groove 62 formed on the lower surface of the base 50 . Of course, the number of wiping members 52 is not limited to two, and may be one or three or more. Also, the wiping member 52 may not necessarily have a tubular shape with a circular cross-section, and may be a tube with an elliptical cross-section or a fan-shaped cross-section.

Returning to FIG. 2, the fluid supply device 31 is a device that supplies fluid at a predetermined pressure into the wiping member 52 through a fluid supply path 54 formed in the base 50. For example, when air is used as the fluid, An air compressor is used if available. Moreover, it is preferable that the fluid supply device 31 can change the pressure of the fluid to be supplied at any time. Thereby, the outer dimensions of the wiping member 52 can be set to a desired size by changing the pressure of the supplied fluid.

The cleaning cloth supply mechanism 32 is a mechanism for supplying the cleaning cloth C to the cleaning head 30 and generally includes a pair of cross rolls 64 and a cross guide 66 .

Every time one cleaning operation (for example, an operation of cleaning from one end to the other end of a piece of cleaning target 3D glass G) is completed, the cleaning cloth supply mechanism 32 supplies an unused cleaning cloth in the next cleaning operation. One cloth roll 64 is pulled from the other cloth roll 64 so that the portion C is located under the base 50 and the wiping member 52 so that the unused portion of the cleaning cloth C can be cleaned. The state of the cleaning cloth C is controlled by winding the cloth C. A new portion of the cleaning cloth C is supplied every time one end of the 3D glass G to be cleaned is cleaned from one end to the other end, but the present invention is not limited to this. A new portion of the cleaning cloth C may be supplied.

The cleaning liquid supply device 34 is a device for supplying a predetermined amount of cleaning liquid to the unused portion of the cleaning cloth C sent under the base 50 and the wiping member 52 . In this embodiment, alcohol is used as the cleaning liquid, but the type of cleaning liquid is not limited to this.

The head driving mechanism 36 is a mechanism that has a role of reciprocating the cleaning head 30 in the first direction X and the second direction Y at high speed. Of course, the number of reciprocations and the width of the head drive mechanism 36 are determined according to the material of the object to be cleaned, the type of the cleaning liquid and the cleaning cloth C, the cleaning quality, and the like. Further, the reciprocating motion of the cleaning head 30 by the head driving mechanism 36 may be continuous reciprocating motion or intermittent reciprocating motion. Furthermore, the head drive mechanism 36 may be moved while the transport unit 20 (3D glass G) is moved by the holding table moving mechanism 26, or when the movement of the transport unit 20 (3D glass G) is temporarily stopped, The head driving mechanism 36 may be moved.

The pressing members 38 are a pair of members arranged on both sides of the cleaning head 30, and each of them is movable in the horizontal (right and left) direction. The cleaning cloth C supplied from the cleaning cloth supply mechanism 32 passes through the gap between the cleaning head 30 (base 50 ) and the pressing member 38 so as to reach from above the base 50 to below the base 50 and the wiping member 52 . It has become.

After the unused portion of the cleaning cloth C is set under the base 50 and the wiping member 52 as shown in FIG. , to prevent the cleaning cloth C from moving undesirably during the wiping operation. The pressing member 38 reciprocates together with the base 50 while the cleaning cloth C is pressed against the base 50 when the base 50 reciprocates.

Returning to FIG. 1 , the reversing mechanism 14 is a mechanism for reversing the vertical direction of the 3D glass G, and is arranged between the cleaning section 12 and the second cleaning section 16 . In the case of this embodiment, the reversing mechanism 14 reverses this while holding the 3D glass G by a non-contact holding mechanism.

As shown in FIGS. 1 and 6, the second cleaning section 16 is arranged side by side with the reversing mechanism 14 and the cleaning section 12, and cleans the upper surface of the 3D glass G reversed by the reversing mechanism 14. As with the cleaning section 12 , the second cleaning section 16 is generally composed of a second conveying section 70 and a second cleaning unit 72 .

The second conveying unit 70 holds and conveys the 3D glass G whose lower surface has been cleaned so that its upper surface faces upward. and a second pedestal moving mechanism 76 that moves the pedestal 74 mainly in the first direction X.

The second holding base 74 holds the 3D glass G with its upper surface facing upward. Therefore, as shown in FIG. 7, the upper surface of the second holding table 74 is formed with a convex portion 78 into which the lower surface of the 3D glass G is fitted. When the 3D glass G, which is an object to be cleaned, is attached to the protrusion 78 formed on the second holding base 74, the 3D glass G is restricted from moving in directions other than upward.

The second pedestal moving mechanism 76 is a mechanism that moves the second pedestal 74 in the first direction X as described above. It should be noted that, similarly to the pedestal moving mechanism 26, the second pedestal moving mechanism 76 includes a motor that generates power to be transmitted to the second pedestal 74 and a guide along the first direction X (and the second direction Y). contains parts.

Returning to FIG. 6, the second cleaning unit 72 comes into contact with the upper surface of the 3D glass G conveyed by the second conveying section 70 to wipe and clean the surface. A device 81 , a second cleaning cloth supply mechanism 82 , a second cleaning liquid supply device 84 , a second head drive mechanism 86 and a second pressing member 88 are provided.

The second cleaning head 80 is composed of a second base 90 and a second wiping member 92, as shown in FIG.

The second base 90, like the base 50, is a member made of a relatively hard material (for example, resin or metal such as aluminum) compared to the second wiping member 92. is formed with a second fluid supply 94 for supplying fluid (eg, liquid, air or other gas) from a second fluid supply 81 (see FIG. 6) to the second wiping member 92. . For example, one end 96 of the second fluid supply path 94 is formed on the upper surface of the second base 90 in FIG. 8, and the other end 98 is formed on the side surface of the second base 90 . The other end 98 of the second fluid supply path 94 is formed at a position communicating with a second fluid intake hole 100 formed in the second wiping member 92 .

A recess 101 in the lower surface of the second base 90 is formed with a second fitting groove 102 into which the second wiping member 92 is fitted. Since the second cleaning head 80 according to the present embodiment also uses two circular tube-shaped second wiping members 92, two second fitting grooves 102 are also formed. Of course, the shape of the second fitting groove 102 is not limited to this, as long as it matches the shape of the second wiping member 92 .

The second wiping member 92 is a relatively soft material (second fluid) disposed from the recess 101 on the lower surface of the second base 90 in FIG. The second wiping member 92 is a member formed of an elastic material such as rubber so that the outer dimensions of the second wiping member 92 change according to the pressure of the fluid supplied from the supply device 81 . The second wiping member 92 according to this embodiment is formed in a circular tube shape as described above, and the second fluid intake holes 100 formed at both ends thereof are formed in the side surfaces of the second base 90 respectively. It is connected to the other end 98 of the second fluid supply path 94 . Also, in this embodiment, two second wiping members 92 are used, each of which is fitted in a second fitting groove 102 formed on the lower surface of the second base 90 . Of course, the number of second wiping members 92 is not limited to two, and may be one or three or more.

The second fluid supply device 81 (see FIG. 6), like the fluid supply device 31, supplies fluid at a predetermined pressure into the second wiping member 92 through a second fluid supply channel 94 formed in the second base 90. For example, an air compressor is used when air is used as the fluid. Moreover, it is preferable that the second fluid supply device 81 can change the pressure of the fluid to be supplied at any time. Thereby, the outer dimensions of the second wiping member 92 can be set to a desired size by changing the pressure of the supplied fluid.

A second cleaning cloth supply mechanism 82 having a second cross roll 104 and a second cross guide 106, a second cleaning liquid supply device 84, a second head drive mechanism 86, and a second pressing member 88 are included in the cleaning unit 22 described above. Since they are basically the same as the cleaning cloth supply mechanism 32, the cleaning liquid supply device 34, the head drive mechanism 36, and the pressing member 38, the explanation of the cleaning unit 22 is used and the description is omitted.

(Operation of cleaning device 10)
Next, the operation of the cleaning device 10 according to this embodiment will be described. First, as an object to be cleaned, an uncleaned 3D glass G is placed in the groove 28 of the holding table 24 of the conveying unit 20 of the cleaning unit 12 with the bottom surface facing upward. Then, the holding table moving mechanism 26 moves the holding table 24 in the first direction X at a constant speed.

When the holding table 24 on which the 3D glass G is placed reaches a predetermined position, the cleaning head 30 contacts the lower surface at one end of the 3D glass G as shown in FIG. When the cleaning head 30 reaches one end of the 3D glass G, the head driving mechanism 36 starts cleaning operation (reciprocating motion).

While the conveying unit 20 conveys the 3D glass G in the first direction X, the cleaning head 30 wipes off the lower surface of the 3D glass G via the cleaning cloth C supplied from the cleaning cloth supply mechanism 32 .

The wiping member (tube) 52 in the cleaning head 30 is supplied with air of a predetermined pressure from the fluid supply device 31 in advance (for example, when the cleaning device 10 is powered on) through the fluid supply path 54 and the like. , and the wiping member 52 is set to predetermined outer dimensions.

When the cleaning unit 12 completes the wiping operation of the lower surface of the 3D glass G, the 3D glass G leaves the cleaning unit 12 and is turned over by the reversing mechanism 14 so that the upper surface faces upward. be transported.

In the second cleaning unit 16 that receives the 3D glass G with its upper surface facing upward, the second cleaning head 80 contacts the upper surface of the 3D glass G at one end, as shown in FIG. . When the second cleaning head 80 reaches one end of the 3D glass G, the second head driving mechanism 86 starts cleaning operation (reciprocating motion).

While the second conveying unit 70 conveys the 3D glass G in the first direction X, the second cleaning head 80 moves the upper surface of the 3D glass G through the cleaning cloth C supplied from the second cleaning cloth supply mechanism 82 . wipe it off.

When the cleaning of the upper surface of the 3D glass G by the second cleaning unit 16 is completed, the cleaning operation by the cleaning device 10 is completed.

(Characteristics of cleaning device 10)
The cleaning device 10 according to the present embodiment is made of a relatively soft material (for example, an elastic body such as rubber), and is supplied with fluid from the fluid supply device 31 (second fluid supply device 81). Since the wiping member 52 (second wiping member 92) is used, the wiping member 52 (second wiping member 92) is deformed (expansion and contraction) according to the shape of the object to be cleaned without external force. As a result, the wiping member 52 (second wiping member 92) can be pressed substantially uniformly across the width of the surface of the object to be cleaned (3D glass G) via the cleaning cloth C. Further, according to the cleaning device 10 of the present embodiment, even if there are individual differences among the objects to be cleaned, that is, even if the dimensions, angles, etc. of the objects to be cleaned are slightly different, the entire surface in the width direction can be substantially cleaned. It can be pressed evenly. It should be noted that "deforming the wiping member 52 (second wiping member 92) by an external force" means, for example, that the wiping member 52 (second wiping member 92) formed of a flexible member such as a sponge It means that the shape is changed simply by pressing against the object to be cleaned. Conversely, "to deform without external force" means to deform the shape of the wiping member 52 (second wiping member 92) using a fluid or the like without pressing it against the object to be cleaned ( See Modification 6, which will be described later). In other words, "to deform without external force" means to deform all or part of the head by applying a deformation factor such as power or fluid to part or all of the head. means. Here, deformation factors include power, electric power, fluid, heat, light, magnetism, signals, and the like. Furthermore, deforming the wiping member 52 (the second wiping member 92) by bringing the cleaning cloth C into contact with it also corresponds to "deforming without external force". In addition, by adjusting the amount of liquid (such as cleaning liquid) contained in the wiping member 52 (second wiping member 92) formed of a flexible member such as a sponge, the wiping member 52 (second wiping member 92) ) also corresponds to “deformation without external force”. Furthermore, it is also possible to deform the wiping member 52 (second wiping member 92) by pulling the edge or the like of the wiping member 52 (second wiping member 92) formed of a flexible member. It corresponds to "transform without".

As a result, even if the object to be cleaned (3D glass G) is a 3D glass G that has a flat portion and, for example, a curved portion that rises from the edge of the flat portion, , can automatically wipe and clean the entire surface (bottom and top). That is, the wiping member 52 (second wiping member 92) includes a flat contact portion that contacts the flat portion of the cleaning object (3D glass G) and an edge of the flat portion of the cleaning object (3D glass G). and a curved surface abutment portion that abuts on the curved surface portion that is formed to rise from the base.

Furthermore, since the wiping member 52 (second wiping member 92) and the base 50 (second base 90) for fixing them can be replaced according to the shape of the object to be cleaned, various objects to be cleaned can be cleaned. Able to adapt to shape.

(Modification 1)
In the above-described embodiment, the lower surface of the object to be cleaned (3D glass G) is wiped off first, and then the upper surface is wiped off, but the upper surface may be wiped off first.

(Modification 2)
Further, the reversing mechanism 14 in the above-described embodiment is not an essential component, and for example, an operator may perform reversing operation of the cleaning object (3D glass G).

(Modification 3)
Furthermore, in the above-described embodiment, the cleaning unit 12 and the second cleaning unit 16 are provided. Only the part 12 is sufficient, and the second cleaning part 16 need not be provided.

The shape of the base 50 (second base 90) and the fitting groove 62 (second fitting groove 102) may be changed according to the shape of the wiping member 92). The fitting groove 62 (second fitting groove 102) is not essential, and the wiping member 52 (second wiping member 92) is directly attached to the surface of the base 50 (second base 90) using an adhesive or the like. may be installed. Further, instead of the fitting groove 62 (second fitting groove 102) for attaching the wiping member 52 (second wiping member 92) to the base 50 (second base 90), the base 50 (second base 90) ) may be formed with a holding portion for holding the wiping member 52 (second wiping member 92).

(Modification 5)
In addition, in the above-described embodiment, the cleaning cloth C impregnated with the cleaning liquid was used to wipe off the upper and lower surfaces of the object to be cleaned (3D glass G). After wiping off the surface of the object to be cleaned (3D glass G), the conveying unit 20 (second conveying unit 70) returns the object to be cleaned (3D glass G) in the direction opposite to the first direction, and the cleaning liquid is applied this time. The object to be cleaned may be wiped dry with a cleaning cloth C that does not contain (or contains only a small amount of cleaning liquid).

(Modification 6)
In the above-described embodiment, tubes are used as the wiping members 52 (second wiping members 92). A material containing a fluid may be expanded and contracted by the fluid. For example, when a sponge or the like is used, it is possible to correspond to the shape of the surface to be wiped of the object to be cleaned simply by changing the amount of fluid supplied to the wiping member 52 (second wiping member 92), that is, the pressure. Furthermore, a piezo element or the like whose shape can be changed by applying a voltage may be used for expansion and contraction of the wiping member 52 (second wiping member 92). Also, the shape may be changed by thermal expansion or the like. In any case, the wiping member 52 (second wiping member 92) is deformed by an external force (for example, the shape is changed by simply pressing a flexible member such as a sponge against the object to be cleaned). ), other means may be adopted.

(Modification 7)
In the above-described embodiment, the cleaning head 30 (second cleaning head 80) is reciprocated by the head driving mechanism 36 (second head driving mechanism 86). The driving mechanism 86) may be omitted so that the cleaning head 30 (second cleaning head 80) does not reciprocate. It should be noted that reciprocating movement of the cleaning head 30 (second cleaning head 80) is preferable in that the object to be cleaned can be cleaned more cleanly.

(Modification 8)
Further, in the above-described embodiment, the fluid supply path 54 (second fluid supply path 94) is formed in the base 50 (second base 90), but instead of this, the base 50 (second base 90) A fluid supply member having a flow path therein may be arranged outside of the , and the flow path may be used as the fluid supply path 54 (second fluid supply path 94).

(Modification 9)
Further, in the above-described embodiment, an example of cleaning the surface of the 3D glass G as an object to be cleaned has been described, but the object to be cleaned is not limited to glass, and can be transparent or non-transparent.

(Modification 10)
Further, in the above-described embodiment, one cleaning head 30, 80 is used for each side of the object to be cleaned (3D glass G), but two or more cleaning heads 30, 80 may be used for one side good.

(Modification 11)
Further, the shape of the holding table 24, 74 for the object to be cleaned (3D glass G) is not limited to the shape in the embodiment, and the object to be cleaned (3D glass G) is not moved undesirably during wiping cleaning. It may be of any shape as long as it can be held in such a manner.

(Modification 12)
In the above-described embodiment, the cleaning head 30 (second cleaning head 80) indirectly contacts the object to be cleaned (3D glass G) through the cleaning cloth C. The cleaning head 30 (second cleaning head 80) may be brought into direct contact with the object to be cleaned (3D glass G) without using the cloth C.
