Preferably, the press mechanism includes upper holder block, lower lock block, push rod, flexible connector and multiple linear axis It holds, the push rod is fixed at the top of upper holder block, and the lower lock block is placed in immediately below upper holder block and is equipped between buffering therebetween Gap, the flexible connector are fastened between upper holder block and lower lock block, and multiple linear bearings are separately positioned on pressure It is cooperatively connected in block and lower lock block and with guide rod, the claw type pressure head is fixedly connected on the side of upper holder block.

Preferably, the linear bearing quantity is set as four, two of them are symmetrically placed in upper holder block two sides, in addition two It is a to be symmetrically placed in lower lock block two sides.

Preferably, the flexible connector be set as include screw and spring combined connection component, screw connection Upper holder block and lower lock block, the spring are located on outside screw.

Preferably, when the lower lock block of the press mechanism is moved to guide rod bottom end, the claw type pressure head and guide rod Vertical range having the same between the vertical interval of bottom end, the LED lamp circuit plate being placed on pedestal and guide rod bottom end.

Preferably, the spacing of the buffer gap is less than the height of shading foam.

Compared with prior art, usefulness of the present invention is: the LED light shading foam assembling fixture is used shading Foam is placed on the press mechanism with claw type pressure head, and foam is pasted on to the LED light being placed on pedestal by press mechanism The corresponding position of circuit board, thus, it is avoided that foam when manpower installation deforms and foam is caused to paste dislocation, to avoid leaking The problem of light or LED light cause half-light by foam covering, and overall structure is easy to operate, and packaging efficiency is high, reduces artificial Intensity, and product yield is improved, thus practicability is high and has high economic benefit, and is suitble to promote and apply.

Detailed description of the invention:

The following further describes the present invention with reference to the drawings:

Fig. 1 is positive structure schematic of the invention；

Fig. 2 is side structure schematic diagram of the invention.

Specific embodiment:

With reference to the accompanying drawing and specific embodiment the present invention will be described in detail:

A kind of LED light shading foam assembling fixture as shown in Figure 1 and Figure 2, is mainly used for shading foam being pasted on LED LED light corresponding position on lamp circuit board, it is described including press mechanism, guide rod 1 and the pedestal 2 for placing LED lamp circuit plate 1 quantity of guide rod is set as two and is vertically arranged, and the pedestal 2 passes through guiding close to 1 bottom end of guide rod, the press mechanism It bar 1 and can freely be slided up and down on guide rod 1, the press mechanism is equipped with a claw type pressure head 3, and the claw type pressure head 3 wraps Four pressure head single-columns 5 to match with the location layout of the LED light on LED lamp circuit plate are included, shading foam to be assembled is placed on It is interference fitted on the pressure head single-column 5 and between pressure head single-column 5, pressure mechanism drives claw type pressure head 3 to be placed on claw type pressure head 3 On shading foam paste on LED lamp circuit plate, preferably, driven to further facilitate the press mechanism Claw type pressure head realizes that pressing action, the press mechanism include upper holder block 7, lower lock block 8, push rod 9, flexible connector and multiple Linear bearing 10, the push rod 9 are fixed on the top of upper holder block 7, the lower lock block 8 be placed in immediately below upper holder block 7 and the two it Between be equipped with buffer gap 11, the flexible connector is fastened between upper holder block 7 and lower lock block 8, preferably, In practical application, the flexible connector can be set to include screw 12 Yu spring 13 combined connection component, the screw 12 connection upper holder blocks 7 and lower lock block 8, the spring 13 are located on outside screw 12 so that upper holder block and lower lock block it Between have a cushion space, avoid contacting firmly between shading foam and LED lamp circuit plate, effectively play buffer function, enhance Its sticking effect, and multiple linear bearings 10 are separately positioned in upper holder block 7 and lower lock block 8 and cooperate with guide rod 1 and connect It connects, the claw type pressure head 3 is fixedly connected on the side of upper holder block 7.

For further to facilitating what press mechanism consolidated on the guide bar freely to slide up and down, 10 quantity of linear bearing Four are set as, two of them are symmetrically placed in 7 two sides of upper holder block, other two is symmetrically placed in 8 two sides of lower lock block, symmetrically arranged Linear bearing enhances the balance and stability when upper holder block and lower lock block operation, enhances the effect of the stickup of shading foam Fruit.

And in practical applications, when the lower lock block 8 of the press mechanism is moved to 1 bottom end of guide rod, the claw type pressure head 3 It is having the same between 1 bottom end of vertical interval, the LED lamp circuit plate being placed on pedestal 2 and guide rod of 1 bottom end of guide rod to hang down Straight distance, and the spacing of the buffer gap 11 is less than the height of shading foam, when guaranteeing that press mechanism presses to final position, Shading foam on the claw type pressure head can be effectively pasted on LED lamp circuit plate, and paste process is stable and sticking effect is good.

During actual assembled, after press mechanism and pedestal, guide rod are directed at positioning according to actual needs, then will The LED lamp circuit plate for needing to assemble is placed on pedestal, and shading foam is located on the pressure head single-column on claw type pressure head, due to It is interference fitted, thus the firm set of shading foam thereon and can be not easy between the through-hole and pressure head single-column of shading foam It falls, then pushes push rod down, then upper holder block and lower lock block is driven to move down along guide rod, led when lower lock block is moved to When to bar bottom end, at this point, shading foam lower part on the claw type pressure head being fixed on upper holder block just with the LED that is placed on pedestal Lamp circuit board is in contact, and then, continuing to press on push rod makes upper holder block continue to move down down, due to the presence of buffer gap, can make It obtains upper holder block to continue slowly to push, to drive claw type pressure head thereon to continue pushing shading foam, so that shading foam Compression is sufficiently contacted and pasted with LED lamp circuit plate, after upper holder block to after contacting with lower lock block, push rod is pushed up to move, it will Press mechanism moves up, and then completes the paste process of entire shading foam.

The LED light shading foam assembling fixture uses and shading foam is placed on the press mechanism with claw type pressure head, And foam is pasted on to the corresponding position for the LED lamp circuit plate being placed on pedestal by press mechanism, thus, it is avoided that manpower is pacified Foam when dress deforms and foam is caused to paste dislocation, so that light leakage or LED light be avoided to cause asking for half-light by foam covering Topic, and overall structure is easy to operate, and packaging efficiency is high, reduces artificial intensity, and improve product yield.

It is emphasized that: the above is only presently preferred embodiments of the present invention, not make in any form to the present invention Limitation, any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention, All of which are still within the scope of the technical scheme of the invention.
