Description

Substrate is with blocking casket

Technical field

The present invention relates to a kind of substrate with the card casket, particularly relate to a kind of substrate that the substrate deformation degree is minimized card casket.

Background technology

The card casket of the substrate S of general carrying LCD and plasma display etc. is to use the card casket 1 shown in Figure 1A, and the design of legacy card casket 1 can make substrate S present spill in card casket 1, shown in Figure 1B.When lifting on the substrate S, substrate S can present convex, shown in Fig. 1 C in mechanical arm R stretches into card casket 1.The effect that therefore substrate S can bear alterante stress, and, can increase the possibility that substrate S recurring structure fatigue damages in long-time effect of bearing alterante stress down.

Simultaneously, along with the size of substrate S constantly increases, attenuation, and in order to overcome above-mentioned substrate S problem on deformation, other have a kind of as No. 357426 disclosed card casket 2 of patent of Taiwan patent announcement except both sides provide support, and increased the design of back up pad 2a in the rear, to reduce the distortion of substrate S, as shown in Figure 2.

Yet, because the size of film crystal liquid substrate is promoted to 730mm * 920mm or bigger 1100mm * 1250mm by original 620mm * 750mm, its thickness also is kept to 0.5mm by original 0.7mm, therefore after the size increase and thickness attenuation of substrate, the influence that curved substrate caused is also just more for obvious, card casket 1,2 in the past can produce problems when bearing substrate, be described below respectively:

1. use the card casket 1 of supported on both sides so can cause the processing quality of substrate effectively to grasp because substrate size becomes big and weight becomes heavy and produces the distortion that differs from the past.

2. 1 strong point by both sides of card casket in the past comes supporting substrate, and like this as substrate is positioned on two parallel lines, so substrate seismism easily takes place and instability.

3. use card casket 2 in the past is the flexural deformation for fear of substrate, the flexural deformation but the load that can make back up pad 2a is excessive, because back up pad 2a is a long and narrow cantilever beam structure, the characteristic of this kind structure can make back up pad 2a that the possibility of distortion is arranged, moreover, as avoiding back up pad 2a distortion, then need strengthen its material and become the change shape, so can cause the weight increase and the volume of card casket 2 to become big, influence blocks the carrying of casket 2 and deposits.

Because the danger that excessive curved substrate will cause base plate stress to concentrate and break, and during with mechanical arm taking-up substrate, also need consider distortion and the stress of substrate on mechanical arm.Because mechanical arm must be put into board with substrate and process, so the design of mechanical arm can not be too complicated.Therefore, it is minimum that the design of card casket must be satisfied the deflection of substrate in the card casket, and simultaneously, substrate also must be kept minimum distortion on mechanical arm.

Summary of the invention

In view of this, the objective of the invention is to provide a kind of substrate with blocking casket, bracing or strutting arrangement by improvement card casket both sides, and the bracing or strutting arrangement of both sides is become the design of two support bars that project upwards, so that base plate carrying can be more steady in the card casket time, and the substrate deformation amount can be controlled in the reasonable range.

The present invention adopts as detailed below feature to solve the above problems basically.That is to say that the present invention is applicable to bearing substrate, and comprise a top frame; One underframe; One frame is to be arranged between this top frame and this underframe; One stop member is to be arranged between this top frame and this underframe, breaks away from this substrate with blocking casket in order to prevent this substrate; And a plurality of bearing supports, be to be relatively arranged between this top frame and this underframe, and be positioned at this top frame and this underframe, each bearing support has a plurality of supporting seats arranged side by side up and down, wherein, each supporting seat has two support bars that project upwards, and is in order to carrying this substrate, and reduces this substrate deformation amount.

Simultaneously, substrate according to the present invention is with blocking casket, and these support bars of each supporting seat are to have different height.

Again in the present invention, these supporting seats and these support bars are to be integrally formed on each bearing support.

Again in the present invention, these bearing supports are to be locked in this top frame and this underframe respectively by screw.

Again in the present invention, these bearing supports are made by a plastic material, to alleviate the weight of these bearing supports.

Again in the present invention, this plastic material is to be polyaryletherketone.

For above-mentioned purpose of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly and conjunction with figs. elaborate.

Embodiment

Existing conjunction with figs. illustrates preferred embodiment of the present invention.

See also Fig. 3, Fig. 4 and Fig. 5, substrate of the present invention comprises a top frame 110, a underframe 120, a frame 130, three stop members 140 and 14 bearing supports 150 with card casket 100.Frame 130 is to be arranged between top frame 110 and the underframe 120.Three stop members 140 are to be arranged between top frame 110 and the underframe 120, and are available to prevent that substrate S breaks away from substrate with blocking casket 100.14 bearing supports 150 are to be relatively arranged between top frame 110 and the underframe 120, and are positioned at top frame 110 and underframe 120, that is to say, are respectively arranged with seven bearing supports 150 at substrate on the relative side that blocks casket 100, as shown in Figure 3.These bearing supports 150 have a plurality of supporting seats 152 arranged side by side up and down, as shown in Figure 4.These supporting seats 152 have more two support bar 154a, the 154b that projects upwards, and are in order to bearing substrate S, and reduce the deflection of this substrate S.

In addition, supporting seat 152 and two

support bar

154a, 154b are integrally formed on the bearing support 150, and bearing support 150 is to be locked in top frame 110 and this underframe 120 respectively by screw (figure does not show).

Simultaneously, in order to alleviate the weight of bearing support 150, bearing support 150 is made by a kind of high rigidity plastic material, for example polyaryletherketone (PEEK).

See also Fig. 6, in the present embodiment, supporting seat 152 is to adopt to have differing heights two support bar 154a, 154b.When substrate S be positioned over two support bar 154a, when 154b is last, substrate S can nature present a less distortion, and stress distribution is average, and becomes a kind of static state, and then during by mechanical arm R carrying, substrate S just is unlikely to produce sliding phenomenon.

Because substrate S can make surperficial coating film treatment earlier, if the surface area of substrate S is bigger, then the control of its surface coating just more shows difficulty, this substrate S in deposit and handling process in take place more obvious because of distortion.For example card casket 1 in the past produces serious deformation because of meeting makes substrate S, so the homogeneity of its surface coating can variation.

Please consult Fig. 5 again, when being positioned over substrate S on the substrate usefulness card casket 100 of the present invention, because substrate has 14 bearing supports 150 with card casket 100, therefore the weight of substrate S is to share out equally on 14 support bar 154a and 14 support bar 154b, thereby reduces the problem of stress concentration of substrate S.

Therefore, substrate of the present invention can be by the bearing support 150 structures shortcoming of blocking casket 1 with certain improvement after the improvement in the past with card casket 100, substrate of the present invention is to reduce the possibility that gross distortion takes place substrate S in the transfer process with the characteristics of card casket 100, goes forward side by side and the occurrence frequency and the degree of distortion may be minimized.

Please consult Fig. 6 again, because supporting seat 152 of the present invention is designs of adopting two

support bar

154a, 154b, when carrying substrate S, mechanical arm R can be placed between two support bar 154a, the 154b, again because the stress distribution in the substrate S is average and distortion is little, therefore after mechanical arm R lifts substrate S, the profile of substrate S with lift before almost present similar shapes, as shown in Figure 7, therefore can avoid the repeated deformation of substrate S in transport process.

In addition, still have another advantage, that is, can avoid mechanical arm R to touch the substrate S that friction is positioned at the below when lifting in stretching into two support bar 154a of the present invention, 154b bearing substrate S.

Though the present invention is disclosed in preferred embodiment; but it is not in order to limit the present invention; any those who familiarize themselves with the technology; do not breaking away from the spirit and scope of the invention; should do a little change and retouching, so protection scope of the present invention is as the criterion when looking the accompanying Claim scope person of defining.
