In particular, the air hole penetrating through the front seat is arranged at the position lower than the whole height of the front seat groove.
In particular, the number of said air holes is at least two, respectively close to the two lower edges of lower height.
The utility model discloses can prevent at the technological process of laminating LCD screen that the backlight from removing or string position, and simple structure, easy machine-shaping, low in manufacturing cost, operating method are simple, easily get on hand, use and maintenance cost are lower.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
FIG. 2 is a schematic structural diagram of an automatic feeding platform.
The labels in fig. 1 and 2 are explained as follows:
1. positioning a base; 2. a middle stay bar; 3. positioning a front seat; 31. a front seat groove; 32. a clamping device; 321. a card is pushed; 322. a spring; 323. a top clamping cover; 33. carving holes; 34. and (4) air holes.
Detailed Description
As shown in fig. 1 and fig. 2, a liquid crystal display backlight positioning device includes a positioning front seat 3, a middle stay bar 2, and a positioning base 1, where the positioning base 1 is located at the bottom, the positioning front seat 3 is located at the upper part, and two ends of the middle stay bar 2 are respectively connected to the positioning base 1 and the positioning front seat 3; the positioning front seat 3 is provided with a front seat groove 31 which inclines downwards, and a clamping device 32 is arranged on the front seat groove 31. The front seat recess 31 is used for accommodating the backlight source, and the locking device 32 is used for fixing and positioning.
The positioning front seat 3, the middle stay bar 2 and the positioning base 1 are all made of plastic materials, so that the cost is reduced.
The front seat recess 31 is square as a whole, and the square includes rectangle and square to correspond to the shape of the backlight.
The edge of the front seat groove 31 is provided with a hollow position 33, so that a product can be taken conveniently in the production process.
The position-locking device 32 is installed at the corner corresponding to the highest height of the front seat groove 31, so as to realize the downward positioning from the high position.
The clamping device 32 comprises a top clamp 321 and a spring 322 positioned at the rear end of the top clamp 321, the top clamp 321 is positioned at the corner with the highest height of the front seat groove 31, and the position stressed when the top clamp 321 is used for positioning is a place with higher strength of the corner of the backlight source, so that the product cannot be damaged, and the clamping device 32 is superior to other clamping devices 32.
The locking device 32 further includes a top locking cover 323 above the top locking device 321 and the spring 322, and the top locking cover 323 is used to cover and protect the top locking device 321 and the spring 322 from damage.
The whole height of the front seat groove 31 is lower than the whole height of the front seat groove, and an air hole 34 penetrating through the front seat 3 is arranged, so that the product can be placed and taken conveniently.
The number of the air holes 34 is at least two, and the air holes are respectively close to two lower edges with lower height, so that the lower part of the backlight source is ensured to have at least one air hole 34 when the shape and the size of the backlight source are different.
During the use, push away top card 321 to extreme position, place the backlight in front seat recess 31, because front seat recess 31 is the decurrent square structure of slope, because the action of gravity, the backlight can slide down to front seat recess 31's lower limb, and the thrust of spring 322 makes top card 321 protractile and push up the backlight to realize the accurate location of backlight. Therefore, the backlight source cannot move or be in serial position in the process of attaching the liquid crystal display, and the bonding precision is improved.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by equivalent substitutions or equivalent transformations fall within the protection scope of the present patent claims.
