Embodiment
Implementation procedure below in conjunction with Figure of description to the utility model embodiment is elaborated.
The utility model embodiment mono-, provide a kind of measuring head for optical tester, as shown in Figure 1, comprising: measuring head main body 1, support component 2 and link 3; Measuring head main body 1 is for obtaining the optical parametric of liquid crystal panel to be tested; Support component 2 has hollow space 21(with reference to figure 2), support component 2 is fixing by link 3 with the measuring head main body 1 be positioned in hollow space 21, for support test head main body 1.
The structural representation of support component 2 as shown in Figure 2, it is shaped as the truncated cone, has hollow space 21.Certainly, support component 2 is not limited to the truncated cone shown in Fig. 2, can be also other three-dimensional shapes.
In the present embodiment, by the support component 2 be fixedly connected with measuring head main body 1, while making the liquid crystal panel to be tested of placing at testing level, measuring head main body 1 is relatively stable, reduces the phenomenon of the damage liquid crystal panel to be tested that skews.
The utility model embodiment bis-, a measuring head provided, have structure as similar as Fig. 1 in conjunction with the embodiments, and difference is, and measuring head also comprises sucker 4 as shown in Figure 3, and sucker 4 is fixed in support component 2 lower ends.The schematic diagram of sucker 4 as shown in Figure 4, sucker 4 centers be provided with one make measuring head main body 1 by and the hole 41 that fits tightly with measuring head main body 1.It should be noted that, hole 41 and the measuring head main body 1 of sucker 4 fit tightly, and when sucker 4 acts on smooth flat, hole 41 has good sealing with the joint place of measuring head main body 1, to guarantee the suction-operated of sucker 4.Certainly the requirement based on better effect, can by hole 41 with the sidewall that contact of measuring head main body 1 arrange thicker so that hole 41 has enough large contact area and better sealing effectiveness during with 1 laminating of measuring head main body.
By sucker 4, measuring head integral body is adsorbed on liquid crystal panel to be tested, and keeps the plane of measuring head main body 1 perpendicular to liquid crystal panel to be tested.Especially when liquid crystal panel to be tested is vertically placed, by sucker 4 absorption, do not need the handheld test head to be tested, while having solved the test of handheld test head, the problem of light leak, avoid test result inaccurate.
The utility model embodiment tri-, in conjunction with the embodiments one or the measuring head that provides of embodiment bis-, have as Fig. 1 or the similar structure of Fig. 3, difference is, bottom margin place at the support component 2 of measuring head is provided with positioning element 5 as shown in Figure 5, and positioning element 5 is the location on the test fluid crystal panel for measuring head.
Usually positioning element 5 comprises at least four cruciform devices that evenly are arranged at the bottom margin of support, can certainly can realize figure of the present utility model for other.When thering is four cruciform devices that evenly arrange, angle between adjacent cruciform device is 90 degree, pattern that can be shown according to liquid crystal panel to be tested is determined needed center, example is shown pattern and the central point A of liquid crystal panel to be tested as shown in Figure 6, this pattern can, for a plurality of, be determined center A according to the positioning element 5 provided in the present embodiment.
When the application testing head is treated the test fluid crystal panel and is tested, damage the liquid crystal panel to be tested of contact with it for fear of measuring head, in conjunction with above-described embodiment one to embodiment tri-, there is the similar structure of measuring head as shown in Fig. 1 or Fig. 3, difference is, measuring head also comprises the cushion pad 6 of the lower end that is arranged at support component 2 as shown in Figure 7.
The utility model embodiment tetra-, be elaborated in conjunction with the link 3 in above-described embodiment.Link 3 can comprise at least two the first links 31 that are arranged at the upper end of support component 2 as shown in figure 12; In such cases, the first link 31 can be screw, and corresponding, as shown in Figure 8 and Figure 9, the zone corresponding with the first link 31, the upper end of measuring head main body is a vertical plane 11, and the upper end of measuring head main body contacts with 31 of the first links.Figure 10 shows measuring head main body 1 and passes through the fixing schematic diagram of the first link 31 with support component 2.
For the first link 31 and the second link 32, following situation is arranged:
The first link 31 is screw, and the second link 32 is nut or draw-in groove; Perhaps,
The first link 31 is nut, and the second link 32 is screw; Perhaps,
The first link 31 is bolt, and the second link 32 is hole or the draw-in groove coordinated with bolt; Perhaps,
The first link 31 is draw-in groove, and the second link 32 is buckle; Perhaps,
The first link 31 is buckle, and the second link 32 is draw-in groove.
For the first link 31 and the second link 32 are described more intuitively, the second link 32 that Figure 11 shows the upper end arranged outside of measuring head main body 1 is the schematic diagram of draw-in groove, it is the schematic diagram of screw that Figure 12 shows the first link 31 arranged on support component 2, this support component 2 can coordinate with the measuring head main body 1 that is provided with draw-in groove (draw-in groove is as the second link 32), by being screwed into the draw-in groove as the second link 32 as the screw of the first link 31, make measuring head main body 1 fixing with support component 2.Certainly, if if the fixing structure (for example fixing draw-in groove or fixing nut) of the second link 32 arranged on measuring head main body 1, the screw of conduct the first link 31 now arranged on support component 2 must movable (for example arranging hole or the drawing lines that can make screw pass through) on support component 2, in order to can be screwed into when mounted in the second link 32.
The second link 32 that Figure 13 shows the upper end arranged outside of measuring head main body 1 is the schematic diagram of draw-in groove, Figure 14 shows on support component 2 the first link 31 is set, and the schematic diagram that the first link 31 is buckle, by will be as the buckle fastening of the first link 31 draw-in groove as the second link 32, make measuring head main body 1 fixing with support component 2.It should be noted that other situations are similar to above-mentioned two situations, give an example no longer one by one at this.
Optionally, the first link 31 and the second link 32 also can adopt magnetic material, and the two is arranged at respectively on support component 2 and measuring head main body 1, and make in support component 2 and measuring head main body 1 fixing by magnetic absorption.
Obviously, those skilled in the art can carry out various changes and modification and not break away from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model also is intended to comprise these changes and modification interior.
