Description
Technical field
The utility model is related to technical field of television sets, more particularly to a kind of liquid crystal TV set backboard flatness detection dress
Put.
Background technology
Liquid crystal TV set backboard is also referred to as display backplane, with the interference of reduction electromagnetic signal, helps the liquid crystal that radiates and make
The effect of TV stable for extended periods of time work.With advances in technology, the size of liquid crystal TV set is gradually to maximization direction hair
Exhibition, thus liquid crystal TV set backboard size also to correspondingly maximization develop.Then except requiring not backboard Sheet Metal Forming Technology
Disconnected to improve outer, the requirement to the flatness of liquid crystal TV set backboard is also increasingly harsh.
At present, using artificial detection more than the flatness detection of liquid crystal TV set backboard.At present, the efficiency manually detected is low
Under, labor intensity is big.The production cost of enterprise can be increased to a certain extent by individually increasing a set of backboard flatness detecting device, and
How to be transformed on the basis of existing production streamline and increase backboard flatness detection function is urgent problem to be solved.
Utility model content
The purpose of this utility model is solution the problems of the prior art, and there is provided a kind of liquid crystal TV set backboard flatness
Detection means, apparatus structure is simple, and part is easy to get, test operation simple and fast, the manual test that directly can be used former workman
Table top integral replacing, has heightened testing efficiency and precision, reduces the labor intensity of workman, and enterprise's production will not be significantly increased
Cost.
The technical solution adopted in the utility model is：
A kind of liquid crystal TV set backboard flatness detecting device, it is characterised in that：Including the workbench being horizontally mounted and work
Make platform to be fixedly mounted at the top of falsework, the upper working face of the workbench is the detection reference plane of flatness detection, on described
The pressure sensor that a cylindricality is mounted with some through holes and each through hole is uniformly offered vertically on working face, it is described
Pressure sensor is connected with the controller being fixed on falsework using wire, and backboard to be detected is placed on pressure sensor
On, a jacking hole is offered at the upper working face regional center position where the through hole, immediately below the jacking hole
Suspension is provided with a cylinder and cylinder sidewall is fixedly connected by support with workbench lower surface, installed in cylinder piston rod top
The push pedal in portion can do vertical motion along jacking hole, and the controller is also connected with the control circuit of cylinder, each pressure sensing
Device pressure value and standard value is identical or deviation is in setting deviation range, cylinder raises backboard top.
Further, the through-hole wall is easy to Fast Installation and torn open with pressure sensor outer wall provided with the screw thread coordinated
Unload replacing.
Further, each pressure sensor top surface protrudes upper working face and each pressure sensor top surface and upper work
Distance is consistent between making face, is that each pressure sensor constitutes a standard detection plane.
Further, device also includes floor push, the control circuit connection of the floor push and cylinder, can be with
Independent control gas cylinder working condition.
Further, one and backboard posting of the same size are also equipped with working face on described, such as passes through spiral shell
Nail is arranged on upper working face, and backboard to be detected can be achieved and quickly positions placement.
The beneficial effects of the utility model are：
The utility model is simple in construction, is made up of workbench and the pressure sensor installed on the table, due to work
Make the detection reference plane that working face on platform is flatness detection, and working face on the top surface and workbench of each pressure sensor
It is that multiple pressure sensors also form a flatness detection face, backboard to be checked is placed in pressure sensor apart from equal, and
The stress value of a certain test point position is measured by pressure sensor, and is compared with the standard value of the test point of early stage typing.
When backboard flatness difference is the presence of uneven phenomenon so that the stress that out-of-flatness region corresponding pressure sensor is measured
Value meeting and standard value have deviation, anyway flatness meets the requirements, the stress value that corresponding pressure sensor is measured can be with standard value phase
Together or in error range.Flatness composite demand, then controller control cylinder operation backboard top is raised, conversely, gas
Cylinder does not work, and need to touch floor push can just work.Apparatus structure is simple, and part is easy to get, test operation simple and fast, can be direct
The manual test table top integral replacing that former workman is used is in the test device in the utility model, has heightened testing efficiency and essence
Degree, reduces the labor intensity of workman, and enterprise's production cost will not be significantly increased.

Embodiment
In order that the advantage of the purpose of this utility model and technical scheme is more clearly understood, below in conjunction with accompanying drawing and reality
Example, the utility model is further elaborated.
As shown in accompanying drawing 1~4, a kind of liquid crystal TV set backboard flatness detecting device, including the workbench 1 being horizontally mounted
And the top of falsework 2 is fixedly mounted in workbench 1, the upper working face 1-1 of the workbench 1 is the detection benchmark of flatness detection
Face, vertical uniformly offer in some through hole 1-2 and each through hole 1-2 is mounted with one on working face 1-1 on described
The pressure sensor 3 of cylindricality, the pressure sensor 3 is connected with the controller 4 being fixed on falsework 2 using wire, is treated
The backboard 7 of detection is placed on pressure sensor 3, is opened at the upper working face 1-1 regional centers position where the through hole 1-2
Provided with a jacking hole 1-3, suspension is provided with a cylinder 5 immediately below the jacking hole 1-2 and the side wall of cylinder 5 passes through support
It is fixedly connected with the lower surface of workbench 1, the push pedal 6 at the top of the piston rod 5-1 of cylinder 5 can be done vertically along jacking hole 1-2
Motion, the controller 4 is also connected with the control circuit of cylinder 5, each pressure value of pressure sensor 3 it is identical with standard value or
Person's deviation is in setting deviation range, and cylinder 5 raises the top of backboard 7.
The through hole 1-2 inwalls are with the outer wall of pressure sensor 3 provided with the screw thread coordinated.
Each top surface of pressure sensor 3 protrudes upper working face 1-1 and the top surface of each pressure sensor 3 and upper working face
Distance is consistent between 1-1.
Device also includes a floor push 8, and the floor push 8 is connected with the control circuit of cylinder 5.
One and the posting 9 of the same size of backboard 7 are also equipped with working face 1-1 on described.
Working method of the present utility model is：
Before test, first the flatness backboard 7 that meets the requirements is placed on device, each test is recorded by pressure sensor 3
Point stress value and so that the value is standard value and sets error range.The backboard 7 sent by streamline is placed in posting 9 by workman
On pressure sensor 3 in region.When the stress value that each test point is measured on pressure sensor 3 is compared with standard value
Compared with.Stress value is equal with standard value or in error range, and the control qigong 5 of controller 4 works and raises the top of backboard 7,
It is that the backboard 7 is qualified products.When backboard 7 has the out-of-flatness such as uneven, warpage region, the corresponding pressure in the region is passed
The stress value and standard value that each test point is measured on sensor 3 differ greatly, and cylinder 5 does not work then, are that the backboard is not conform to
Lattice product is, it is necessary to handle.Workman is touched the underproof top of backboard 7 of the pneumatic cylinder of floor push 8 and raised to be transferred to pin not to be conformed to
Ge Jian areas.
