It can be detected.
Detailed description of the invention
Fig. 1 is that the frame glue of the embodiment of the present invention bonds the use state diagram of force checking device.
Fig. 2 is the partial enlarged view in Fig. 1 at A.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Refering to fig. 1, it can be applied in the embodiment of the present invention without the frame glue bonding force checking device packet being staggered in the liquid crystal cell of side
Clamp assemblies 10, punch assembly 30 and auxiliary top hacking 40 are included, wherein clamp assemblies 10 for clamping glass in a thickness direction
Panel sample 1, here, glass panel sample 1 are the block sample for detection formed after liquid crystal cell is cut, with upper
Laminar substrate, underlying substrate and the frame glue for playing adhesive attraction between the two；Punch assembly 30 includes thimble 31, and thimble 31 is set to folder
It holds by component 10, and the reciprocable on the direction of the clamping face perpendicular to clamp assemblies 10；Auxiliary top hacking 40 is for gluing
It is attached on the substrate for the lower layer that glass panel sample 1 stretches out 10 part of clamp assemblies, and glass panel sample 1 is stretched out in part.
As shown in connection with fig. 2, glass panel sample 1 includes top substrate layer 1a, underlying substrate 1b and frame glue 1c between the two,
Auxiliary top hacking 40 is bonded in the lower surface underlying substrate 1b of glass panel sample 1, here, adhered layer 40a using adhered layer 40a
Bonding force be greater than liquid crystal cell in frame glue 1c bonding force so that auxiliary top hacking 40 paste after will not fall off easily.And it is auxiliary
It helps the hardness for opening piece 40 to be greater than glass panel sample 1, such as uses steel disc.
As one of embodiment, punch assembly 30 is ready-made puller system, in other embodiments, punching press group
Part 30 can also use other forcers with impact force display function.
Specifically, clamp assemblies 10 include for placing the microscope carrier 11 of glass panel sample 1, the branch being fixed on microscope carrier 11
The adjusting rod 14 of frame 12, pressing plate 13 and connecting bracket 12 and pressing plate 13 and 13 distance of adjusting bracket 12 and pressing plate.It is preferred that adjusting rod
14 be screw rod, and end is rotatably connect with pressing plate 13, and middle part passes through bracket 12 and is threadedly engaged with bracket 12,
The other end is nut, conveniently adjusted.Rotating screw cap, adjusting rod 14 can rotate in bracket 12 and in the longitudinal direction (with reference to Fig. 1
Shown direction) it is mobile, to realize the clamping and release of glass panel sample 1 towards or away from microscope carrier 11 with dynamic pressure plate 13, adjust
Section is convenient.
In order to guarantee the stationarity of pressing plate 13 mobile fluency and clamping, clamp assemblies 10 further include being respectively arranged on adjusting
At least two guide rods 15 of 14 two sides of bar, one end of each guide rod 15 are fixed on pressing plate 13, and the other end activity of guide rod 15 is worn
On bracket 12.During rotation adjusting lever 14, the guide rod 15 of 14 two sides of adjusting rod is slided relative to bracket 12, is played
While guiding role, but also pressing plate 13 will not shake, the flatness of clamping face is guaranteed.
The side wall of auxiliary top hacking 40 abuts microscope carrier 11 or auxiliary top hacking 40 is rotatably coupled with microscope carrier 11.?
When test, glass panel sample 1 is clamped in a thickness direction using clamp assemblies 10, and keep glass panel sample 1 to be detected
Clamp assemblies 10 are stretched out in the part of bonding force, and the thimble 31 of punch assembly 30 is right on the direction perpendicular to glass panel sample 1
The part force of glass panel sample 1 is stretched out in auxiliary top hacking 40, the thrust being applied on thimble 31 is gradually increased, until glass
There is lamination in the upper and lower substrates removing of panel sample 1, and tester is applied on thimble 31 under this zero boundary state by reading
Thrust you can get it frame glue bonding force.
It is detected using above-mentioned without the side liquid crystal cell center gluing resultant force that is staggered another object of the present invention is to provide a kind of
The method of device detection block gluing resultant force, comprising:
It pastes auxiliary top hacking 40: in the underlying substrate surface mount auxiliary top hacking 40 of glass panel sample 1, and making auxiliary
It helps and opens 40 part of piece stretching glass panel sample 1；
Clamping glass panel sample 1: the side that glass panel sample 1 does not paste auxiliary top hacking 40 is clamped；
Open the underlying substrate of glass panel sample 1: from top substrate layer side impact auxiliary top hacking 40, until underlying substrate
It is separated with top substrate layer；
Finally, the impact force of record underlying substrate and the top substrate layer time of releasing.
It specifically first tears liquid crystal cell to be determined off polaroid, will be cut into liquid crystal cell along frame glue without border area is staggered
The glass panel sample to be measured of suitable dimension (such as 10cm × 5cm)；Then it is uniformly added into adhesive glue on auxiliary top hacking surface, it should
Rapid-curing cutback glue or double-sided adhesive can be used in adhesive glue；Auxiliary top hacking is adhered to the underlying substrate of sample to be tested again, formation is staggered
Edge；After glue bond to be bonded is secured, sample is placed in top-opening type jig and is fixed, opening underlying substrate using thimble makes it
Removing, it is frame glue bonding force that frame glue, which is opened impulse force suffered by moment,.
Preferably, auxiliary top hacking 40 stretch out glass panel sample 1 part even width it is consistent so that no matter thimble
31 wherein exert a force, and impact force suffered by frame glue is consistent.
The present invention can be tested without the side liquid crystal cell center gluing resultant force that is staggered, and provide number for process monitoring and frame glue analysis of anomaly
According to.By the underlying substrate surface mount auxiliary top hacking in glass panel, auxiliary top hacking and underlying substrate are fixed on one
It rises, opens the i.e. separable top substrate layer in part and underlying substrate that glass panel is stretched out in auxiliary top hacking using thimble, pass through inspection
It surveys underlying substrate and the top substrate layer time of releasing and is applied on thimble and open power you can get it frame glue bonding force, such detection side
Formula high reliablity, is suitable for batch production, and the sample concordant for upper and lower layer glass edge still can detect.
The above is only the specific embodiment of the application, it is noted that for the ordinary skill people of the art
For member, under the premise of not departing from the application principle, several improvements and modifications can also be made, these improvements and modifications are also answered
It is considered as the protection scope of the application.
