The specific embodiment
For making those skilled in the art understand better the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1:
The present embodiment provides a kind of alignment bolt, as shown in Figures 4 to 6, comprises central shaft 3 and the cylinder 4 rotating around central shaft 3, and the outer surface of cylinder 4 is provided with screw thread 11, also comprises the female cylinder blanket 9 of tool.Wherein, 31 pairs of cylinders of the shaft shoulder 4 carry out spacing, and cylinder blanket 9 is enclosed within outside cylinder 4, and is fixed on cylinder 4 by screw thread, and cylinder blanket 9 is for contacting and push that substrate is carried out bit correction with substrate side surfaces.
The alignment bolt of the present embodiment has cylinder blanket 9 at cylinder 4 overcoats, when position that cylinder blanket 9 often contacts with substrate wearing and tearing occurs and when causing aligning accuracy to decline or not meeting aligning accuracy and require, because of cylinder blanket 9 with cylinder 4 for being threaded, can directly cylinder blanket 9 be spun down and be changed, and no longer need alignment bolt to carry out integral replacing, original location parameter of technique base station does not change yet, thereby it is both simple, time saving and energy saving to make to safeguard, reduced again the cost of maintenance of equipment.
Preferably, the length that is shorter in length than cylinder 4 of cylinder blanket 9, when there are wearing and tearing in the position that cylinder blanket 9 often contacts with substrate, can be by rotational circle cylindricality shell 9 to change its axial location on cylinder 4, thereby the part not being worn is contacted with substrate, alignment bolt still can continue to use, and then has extended the service life of cylinder blanket 9, has reduced the maintenance cost of equipment.In addition, why making the length that is shorter in length than cylinder 4 of cylinder blanket 9, is for cylinder blanket 9 is not interfered with original parts.
Further preferred, cylinder 4 is provided with threaded collar 8, and it is positioned at outside one end of cylinder blanket 9, for holding cylindrical shell 9, thereby can prevent that cylinder blanket 9 is in axial direction moved.It should be noted that, in production, alignment bolt is perpendicular to that process area places.Therefore, under this kind of situation, threaded collar 8 should be preferentially located at the lower end of cylinder 4, thereby can prevent that cylinder blanket 9 effect due to gravity when vibrations from moving down.
Further preferred, the other end of cylinder 4 is also provided with threaded collar 8, thus holding cylindrical shell 9 better.
Preferably, in conjunction with Fig. 4 and 6, cylinder 4 has center ladder hole 10, and the two ends of cylinder 4 are built-in clutch shaft bearing 13 and the second bearing 14 respectively.
Further preferred, as shown in Figure 4, the end of central shaft 3 is provided with external screw thread (attached not shown), and nut 12 is set on external screw thread, screws nut 12 with to built-in first the holding axle 13 and be fixed in cylinder 4 ends.Use the mode of nut check rigid bearing to be convenient to installation and removal, thereby make to safeguard more convenient.
Preferably, the built-in pressure inductor of central shaft 3 (attached not shown), further preferred, pressure inductor is column support type pressure sensor.The pressure can direct-detection central shaft 3 being subject to when the contraposition by pressure inductor.The pressure data that when record and collection alignment bolt are normally worked, central shaft 3 is subject to, further pressure data is arranged, empirical data is theorized, the pressure value that only needs Surveillance center's axle 3 to be subject in producing like this, can realize the monitoring to alignment bolt aligning accuracy, thereby can get rid of timely and effectively hidden danger, improve the rate of transferring of equipment.
It should be noted that, the alignment bolt of the present embodiment can be used in production process of liquid crystal displays, glass substrate being carried out bit correction, also can need to carry out the situation to bit correction to substrate for other.
Embodiment 2:
The present embodiment provides a kind of substrate alignment apparatus, and it comprises the alignment bolt in embodiment 1, certainly also comprises as known structures such as driver elements.
When the alignment bolt in the substrate alignment apparatus of the present embodiment is worn, its maintenance or replacing are more simple and convenient, therefore make the function of substrate alignment apparatus more perfect, also for ease of maintenaince.
Be understandable that, above embodiment is only used to principle of the present utility model is described and the illustrative embodiments that adopts, yet the utility model is not limited to this.For those skilled in the art, in the situation that not departing from spirit of the present utility model and essence, can make various modification and improvement, these modification and improvement are also considered as protection domain of the present utility model.
