Description
Technical field
The utility model is related to a kind of cam jacking mechanism, and in particular to slow stripping is carried out during a kind of fractionation backlight
Mechanism, belongs to display panel production technical field.
Background technology
With the high speed development of science and technology, flat display apparatus particularly liquid crystal display device (Liquid Crystal
Display, LCD) there is high image quality, small volume, lightweight and have a wide range of application because of it, and be widely used in
In all kinds of consumption electronic products such as mobile phone, notebook computer, desktop display device, TV, and little by little substitution has been passed
The CRT display (Cathode Ray Tube, CRT) of system and turn into the main flow of display device.
Contain backlight in existing liquid crystal display device structure, backlight is to be located at liquid crystal display（LCD）The one of behind
Light source is planted, its illumination effect will directly influence LCD MODULE（LCM）Visual effect.Liquid crystal display is not sent out in itself
Light, it shows that figure or character are its results to light modulation.Backlight it is main by light source, light guide plate, optics matrix,
Structural member is constituted, and the shading rubber belt of fixed and interception (covering the light of marginal ray and lamp position) is played including it
（tape）.
Existing backlight is disassembled and removes shading rubber belt（tape）When operating personnel use finger or palm pressing panel
（Panel）Surface, then to shading rubber belt（tape）Removed.The step is although simple to operate, but due to press dynamics not
Easily control and easily cause locus coeruleus, cause local pixel to show abnormal, affected area bright spot occurs and gathers.And this fixed form
Compare and take time and effort, be unfavorable for popularization and application.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, there is provided a kind of cam jacking mechanism, can be by letter
Single manual control, improves the fractionation success rate of backlight, substantially reduces human error and leads.
According to the technical scheme that the utility model is provided, cam jacking mechanism, including handle, connecting rod, bearing block, cam
Connecting shaft, cam, fulcrum shaft, upper junction plate, fulcrum shaft bearing and base plate；The base plate side is provided with two bearing blocks in left and right,
Cam connecting shaft is connected with two bearing blocks, and the cam connecting shaft is provided with cam；Base plate opposite side is provided with left and right two
Individual fulcrum shaft bearing, fulcrum shaft and two fulcrum shaft bearings are connected；Described upper junction plate one end is fixed on fulcrum shaft.
Described connecting rod one end is connected with bearing block, and the other end is connected with handle.
Described upper junction plate one end is secured by bolts on fulcrum shaft.It is convex that the upper junction plate other end lower section is provided with one
Wheel follower, Cam Follower is connected by follower connector with connecting plate；The Cam Follower lower end is mutual with cam
Contact.
The beneficial effects of the utility model：The utility model simple structure, Operational Mechanisms are clear and definite, it is only necessary to manually shake hand
Handle can complete the separation of backlight, substantially increase fractionation success rate, can also manually control to split speed, be suitable to big rule
Mould application.

Specific embodiment
As shown in Figure 1-2：Cam jacking mechanism, including handle 1, connecting rod 2, bearing block 3, cam connecting shaft 4, cam 5,
Fulcrum shaft 6, upper junction plate 7, fulcrum shaft bearing 8 and base plate 9；The side of the base plate 9 is provided with two bearing blocks 3 in left and right, and cam connects
Spindle 4 is connected with two bearing blocks 3, and the cam connecting shaft 4 is provided with cam 5；The opposite side of base plate 9 is provided with left and right two
Fulcrum shaft bearing 8, fulcrum shaft 6 is connected with two fulcrum shaft bearings 8；Fulcrum shaft 6 is fixed in the one end of the upper junction plate 7
On；
The one end of the connecting rod 2 is connected with bearing block 3, and the other end is connected with handle 1.
The one end of the upper junction plate 7 is secured by bolts on fulcrum shaft 6.The other end of the upper junction plate 7 lower section is provided with
One Cam Follower 10, Cam Follower 10 is connected by follower connector 11 with connecting plate 7；Under the Cam Follower 10
End contacts with each other with cam 5.
During utility model works, display panel to be separated is inserted along upper junction plate 7 first so that upper junction plate
7 are located between two-layer to be separated；Now, artificial swinging handle 1 downwards, handle 1 drives connecting rod 2, and then band moving cam to connect
Spindle 4 is rotated, and cam connecting shaft 4 is rotated and causes that cam 5 is rotated, and bossing pushes up Cam Follower 10, by upper connection
The slow jack-up of plate so that backlight is slowly separated.
