Platform unit 1 involved by present embodiment to such as the display floater of portable communication equipment or touch panel, laminal glass substrate 2 that thickness is approximately below 1mm heat when, glass substrate 2 located on platen 3 and carries in heating furnace time use.Also the pallet etc. of the tabular used as described above is comprised in platform unit 1.In the present embodiment, the platform unit 1 for the rectangular glass substrate 2 of mounting is described for example.
As shown in Figure 1 and Figure 4, platform unit 1 possesses substantially: the platform 3 of pottery system, and on the platform 3 of this pottery, mounting will carry out the glass substrate 2 heated; Multiple hole portion 4; It is arranged in the position positioned glass substrate 2 on this platform 3, and runs through formation along the vertical direction; Multiple metal spacer 5, it is configured in above-mentioned multiple hole portion 4 respectively; And metal connecting rod 6, its arrange on platen 3 and spacer 5 each other.
As shown in Figure 1, the platform 3 of pottery system has the area larger than placed glass substrate 2.The position positioned glass substrate 2 on platen 3, is arranged with eight holes portion 4 in the mode of surrounding the mounting region R loaded for being located by glass substrate 2.The number in hole portion 4 sets as required.The inner surface in hole portion 4 is formed as barrel surface, and the axle of this barrel surface is along above-below direction.Each limit of four limit 2a that eight holes portion 4 has along glass substrate 2 and configure and two places are set on each limit, to make at least to position these four limit 2a.
Fig. 2 illustrates an example of the spacer 5 forming platform unit 1.In spacer 5, rest pad portion 7 and pin portion 8 form.As shown in Fig. 2 (a), it is the widest and along with the spindle shape narrowed gradually towards the both ends width on the length direction of left and right that the planar profile outline-shaped in rest pad portion 7 becomes central portion on the length direction of left and right, or formed with gradient.
As shown in Fig. 2 (b), for the height in rest pad portion 7, left and right length direction is formed as identical height, end face 7a and bottom surface 7b is formed as tabular surface.As shown in Fig. 2 (a) He (c), the end face 7a in rest pad portion 7, along the left and right length direction in rest pad portion 7, is formed as roughly fixed width and rectangle in the gamut between its both ends.The bottom surface 7b in rest pad portion 7 is formed as above-mentioned spindle shape etc.
For the side of two on the width of the positive and negative in rest pad portion 7, respectively lower side face is formed as launched portion 7c, upper side face is formed as slope 7d.Specifically, on the width in rest pad portion 7, a pair lower side face of positive and negative is formed as launched portion 7c respectively, this launched portion 7c erects less perpendicular and is formed from the bottom surface 7b of spindle shape, and releases laterally gradually from the both ends the left and right length direction in rest pad portion 7 towards central portion.The position that the release of launched portion 7c is maximum becomes the most advanced and sophisticated 7e of release.Upper side face is formed as the downward-sloping slope 7d in upper end from rectangular end face 7a towards launched portion 7c.
The left and right lengthwise dimension of the appearance and size in rest pad portion 7, at least rest pad portion 7 is formed as larger than the internal diameter in the hole portion 4 being formed at platform 3.The width full-size (releasing the width dimensions of most advanced and sophisticated 7e position) in rest pad portion 7 is identical with the outside dimension in the pin portion 8 inserting hole portion 4.That is, pin portion 8 and release most advanced and sophisticated 7e not have ladder difference and continuous print mode is formed smoothly.And, contact with the upper surface face of platform 3 than the bottom surface 7b in rest pad portion 7 in the outer part of pin portion 8.The end face 7f at the both ends on the left and right length direction in rest pad portion 7 is being formed from bottom surface 7b to less perpendicular in the gamut of end face 7a.
In the example in the figures, rest pad portion 7 is formed in the mode that left-right parts is identical relative to central portion on the length direction of left and right.But, also can with the central portion relative to the most advanced and sophisticated 7e of the release comprising greatest width dimension, the different mode of right side size grade shorter in left side size is formed.In addition, rest pad portion 7 in its width direction, is also formed in the mode that positive and negative is identical, but also can be formed in the mode that positive and negative is different.But, if as in the example as illustrated, left and right length direction and positive and negative width are formed in an identical manner, does not then limit the direction of use, therefore, it is possible to convenience when improving process.
Pin portion 8 hangs down downwards from the bottom surface 7b in rest pad portion 7 and is formed.Pin portion 8 configures with the position consistency ground of the release in rest pad portion 7 most advanced and sophisticated 7e position, i.e. greatest width dimension.In illustrative example, release the central portion on left and right length direction that most advanced and sophisticated 7e position is rest pad portion 7, therefore pin portion 8 is arranged at this central portion.Pin portion 8 is formed as cylinder, and this cylindrical axle is along above-below direction.
The outside dimension in pin portion 8 is set as identical with the greatest width dimension in rest pad portion 7 (releasing the width dimensions of most advanced and sophisticated 7e position), during to make glass substrate 2 to be placed in platform 3 or hook does not occur when platform 3 removes, and, the outside dimension in pin portion 8 is formed as less than the internal diameter size in this hole portion 4, to make it possible to insert the hole portion 4 formed on platen 3.In order to the platform unit 1 involved by present embodiment being used for heat, consider the different of the coefficient of thermal expansion between the platform 3 of the pottery being formed with hole portion 4 and the metal pin portion 8 in insertion hole portion 4, and take into account and avoid 8 pairs, the pin portion platform 3 because of heating after thermal expansion to cause damage, decide the internal diameter in hole portion 4.
In spacer 5, run through along the vertical direction in the gamut of through hole 9 from the end face 7a in rest pad portion 7 to the lower end in pin portion 8 and formed.Preferred through hole 9 is formed along the vertical direction as the crow flies, as long as but formed through manner, then also can not straight along the vertical direction formation.
In addition, in the inner side in rest pad portion 7, from the end face 7f of the end on its left and right length direction, be formed with the insertion section 10 be communicated with through hole 9 along left and right length direction.In illustrative example, one end of insertion section 10 opens outside rest pad portion 7, and the other end is formed by the hole 11 straight be in the horizontal direction communicated with through hole 9.Hole 11 is positioned at the central authorities on the positive and negative width in rest pad portion 7 and is formed.In illustrative example, through hole 9 is formed in the central portion on the positive and negative width in rest pad portion 7, as long as but through hole 9 be communicated with hole 11, then also can form through hole 9 from this central portion staggered positions.
In the present embodiment, illustrate and form the situation of through hole 9, and as the one end in the hole 11 of insertion section 10 and other end both sides open.Also can not form through hole 9, when not forming through hole 9, one end of insertion section 10 is open, and the other end is formed as closed shrinkage pool.But, when forming shrinkage pool, chip likely after the internal residual of shrinkage pool is processed insertion section 10 or trickle dust, can make chip etc. from shrinkage pool, go to outside due to vibration during delivery platform unit 1 etc., when on the surface that this chip is attached to glass substrate 2, likely in the processing of the heating of glass substrate 2, later stage operation, cause harmful effect, thus cause product bad, be therefore preferably formed through hole 9.
As shown in Figure 3, connecting rod 6 is formed by straight clava.The external diameter of connecting rod 6 is formed as less than the internal diameter in hole 11, to make this connecting rod 6 vacate a little gap relative to hole 11, and does not damage each other in thermal expansion.As shown in Figure 4, the end 6a of connecting rod 6, along the length direction in the hole 11 of the insertion section 10 of spacer 5, plugs the hole 11 of the insertion section 10 of inserting spacer 5 freely.
As shown in Figure 5, determine the size of space P (with reference to Fig. 1 and Fig. 5 (b)) in hole portion 4 as follows: make connecting rod 6 have enough and to spare relative to the inner surface 9a of the through hole 9 faced by the 6a of its end, to make connecting rod 6 not interfere with this inner surface 9a when extending because of thermal expansion, and connecting rod 6 is made to separate the adeciduate gap when connecting rod 6 is partial to a side in rest pad portion 7 and in patchhole 11.In other words, the length of connecting rod 6 is decided based on the size of space P in hole portion 4.When not forming through hole 9, insertion section 10 is shrinkage pool, decide the size of space P in hole portion 4 as follows: make the end 6a of connecting rod 6 have enough and to spare relative to the other end closed, and make connecting rod 6 separate the adeciduate gap when connecting rod 6 is partial to a side in rest pad portion 7 and insert in shrinkage pool.
By being inserted in adjacent a pair spacer 5 by the two ends 6a of connecting rod 6, thus as aftermentioned, pin portion 8 inserts hole portion 4 and stops a pair spacer 5 arranged on platen 3 to rotate around hole portion 4 on platen 3 respectively.
Fig. 4 and Fig. 5 illustrates and utilizes spacer 5 and connecting rod 6 on platen 3 to the state that glass substrate 2 positions.When platform unit 1 loads glass substrate 2, use eight spacers 5 and four connecting rods 6.
Before the hole portion 4 pin portion 8 of spacer 5 being inserted platform 3, in advance connecting rod 6 inserted a pair spacer 5 and arrange.That is, the two ends 6a of connecting rod 6 is inserted in the hole 11 of a pair spacer 5 of adjacent configuration, thus installs one group that is made up of above-mentioned a pair spacer 5 and connecting rod 6 on platen 3.
A pair spacer 5 by being linked by a connecting rod 4 side by side point-blank, above-mentioned pin portion 8 loosely insert be arranged in in eight holes portion 4 of the position that rectangular glass substrate 2 positions, towards glass substrate 2 each limit 2a around edge, periphery and in adjacent two hole portions 4.Thus, four limits of the mounting region R of glass substrate 2 are surrounded by four groups of being made up of connecting rod 6 and a pair spacer 5.
Set the length of connecting rod 6 as follows: after pin portion 8 is inserted hole portion 4, even if make connecting rod 6 extend because of thermal expansion also vacate the gap with enough and to spare relative to each through hole 9 of a pair spacer 5, and connecting rod 6 is not also come off when a side in its deflection rest pad portion 7.Under the state utilizing connecting rod 6 to link, be inserted with the orientation of left and right length direction along hole portion 4 in the rest pad portion 7 of each spacer 5 in pin portion 8 to hole portion 4.In addition, the central portion on the left and right length direction in rest pad portion 7 and the position be positioned near it closest to glass substrate 2, specifically release most advanced and sophisticated 7e and be positioned at position closest to glass substrate 2.
By pin portion 8 is inserted in hole portion 4, the mode that the planar bottom surface 7b of the spindle shape in rest pad portion 7 etc. is contacted with face and abutting with platform 3 upper surface, thus spacer 5 entirety is supported on platform 3, therefore, it is possible to the shake etc. of restriction rest pad portion 7 and spacer 5.Meanwhile, owing to being supported on the two ends 6a being inserted into connecting rod 6 in a pair spacer 5 on platform 3, therefore, it is possible to restriction a pair spacer 5 rotates around hole portion 4 on platen 3.
Therefore, the position of spacer 5 is fixed to, prevent the both ends on the left and right length direction of spacer 5 from exceeding situation that the mounting region R of glass substrate 2 etc. changes the direction of spacer 5 on platen 3, and spacer 5 is not interfered with mounting region R.Thus, the most advanced and sophisticated 7e and slope 7d of the release of spacer 5 is positioned at the position towards mounting region R.
Above platform 3, move into glass substrate 2 and this glass substrate 2 is placed in mounting region R.Now, a little position even if glass substrate 2 staggers, also the slope 7d of each spacer 5 is utilized to carry out each limit 2a of the edge, periphery of glass-guiding substrate 2, thus glass substrate 2 suitably and is swimmingly imported mounting region R and can not damage, and by utilizing the most advanced and sophisticated 7e of release to position glass substrate 2 exactly, glass substrate 2 is arranged at mounting region R.
Platform unit 1 involved according to the present embodiment, when utilizing metal spacer 5 to position the glass substrate 2 that the platform 3 of pottery loads, comprise and possessed rest pad portion 7 by the spacer 5 in the pin portion 8 loosely inserted in hole portion 4, the length direction in this rest pad portion 7 is along the orientation in hole portion 4, and there is the bottom surface 7b that abuts with platform 3 upper surface and spacer 5 is supported on platform 3, therefore, can to be contacted with the face of bottom surface 7b by platform 3 upper surface is arranged on platform 3 by spacer 5, even if spacer 5 is arranged at platform 3 with pin portion 8 and the lax relation in hole portion 4, also spacer 5 can suitably be supported, to make its not shake or run-off the straight on platen 3, and can position glass substrate 2, with make its can not because of carry time vibration or mounting, hook and damaged is there is when removing.
Due to rest pad portion 7 is formed as, suitable position on its length direction has the greatest width dimension position (releasing most advanced and sophisticated 7e position) closest to glass substrate 2 compared with other parts, specifically, rest pad portion 7 is formed with the central portion on the length direction of left and right and the neighbouring profile mode closest to glass substrate 2 thereof, and pin portion 8 is hung down from this greatest width dimension position in rest pad portion 7 and is formed, even if therefore make the glass substrate 2 loaded in mounting region R move, also can utilize pin portion 8 and rest pad portion 7 around the edge, periphery of this glass substrate 2, suitably keep the position of this glass substrate 2.
Owing to rotating limiting setting spacer 5 on platen 3 in the insertion section 10 of a pair spacer 5 adjacent for the two ends 6a of connecting rod 6 insertion around hole portion 4 on platen 3, therefore, it is possible to reliably prevent rest pad portion 7 from exceeding mounting region R and making spacer 5 this situation overlapping with glass substrate about 2.
About the contrast of present embodiment and background technology (patent document 1: Japanese Patent No. 5069382 publication), this background technology possesses following structure: link the projected state that this alignment pin keeps alignment pin outstanding on platform by utilizing the coupling member that loosely runs through in the lateral direction penetrating hole of alignment pin, wherein, this alignment pin is loosely inserted in porosity, but in this structure of background technology, suitably cannot support alignment pin do not shake to make it or vibrate, therefore, be difficult to position safely to make glass substrate breakage not occur, but in the present embodiment possessing said structure, different from background technology, even if pin portion 8 and hole portion 4 are set as lax relation, also spacer 5 can reliably be supported, in addition, reliably can also prevent the interference of the position of spacer 5 and glass substrate 2, thus improve the positioning function of the position keeping this glass substrate 2 on platen 3 significantly.
Due to the spindle shape that the central portion planar profile mode in rest pad portion 7 be formed as on its length direction is the widest, or formed with tapering, even if therefore spacer 5 rotates slightly because of connecting rod 6 and the gap of insertion section 10 (hole 11), also can reliably prevent rest pad portion 7 from exceeding mounting region R.
Because the hole 11 utilizing shrinkage pool or be communicated with through hole 9 forms insertion section 10, and make insertion section 10 not run through the opposition side in rest pad portion 7, drop out towards the other end from the end the left and right length direction in rest pad portion 7 therefore, it is possible to prevent being inserted into the connecting rod 6 in rest pad portion 7 via insertion section 10 and come off.
Identical with the greatest width dimension in rest pad portion 7 (releasing the width dimensions of most advanced and sophisticated 7e position) due to the outside dimension in pin portion 8 is set as, therefore, it is possible to reliably prevent from, when glass substrate 2 being placed in platform 3 or when removing from platform 3, hook occurs.
Owing to being formed with through hole 9 on spacer 5, dust running through along the vertical direction in the gamut in pin portion 8 from rest pad portion 7 and be communicated with hole 11, even if therefore enter dust in hole 11, also can be discharged and can not be trapped in inside by this through hole 9.Owing to spacer 5 being configured to configure rest pad portion 7 and pin portion 8 up and down, therefore, it is possible to prevent from obscuring up and down when processing.
As long as the profile form of spacer 5 possesses the function illustrated in above-mentioned embodiment, then it can be arbitrary profile form.Fig. 6 illustrates variation for the profile mode of spacer 5.Illustrate for identical incomplete structure, be only described for different parts.In the spacer 5 involved by variation, rest pad portion 7 is formed as rectangular shape, and is arranged on the left and right sides in the pin portion 8 of cylindrical shape in the mode in pair of right and left rest pad portion 7 integratedly and is formed.In other words, when observing from rest pad portion 7, identical with above-mentioned embodiment, the profile mode of this spacer 5 is that pin portion 8 hangs down integratedly from this rest pad portion 7 and the mode formed.In the position higher than rest pad portion 7, be formed and be configured in directly over pin portion 8 and the frustum of a cone portion 8a of the mode narrowed upward.Frustum of a cone portion 8a is continuous smoothly in pin portion 8, plays a role as above-mentioned slope 7d.The outside dimension in pin portion 8 sets larger than the width size in rest pad portion 7, and pin portion 8 plays a role as above-mentioned launched portion 7c thus, and the outer peripheral face in pin portion 8 can position glass substrate 2 exactly in the same manner as the most advanced and sophisticated 7e of above-mentioned release.
