The one-to-one through-hole in LED light body position of welding；Further include being made for LED lamp insertion positioning using high temperature resistant silica gel
The clamped module of silica gel, the clamped module setting of silica gel are several for LED lamp positioning and position and wave-soldering furnace clamping plate
Clamped groove, the clamped module of silica gel are arranged between wave-soldering furnace clamping plate and cover board through-hole correspondingly.Due to silica gel
Material has certain elasticity, and the LED light body position on the lamp plate is enable to play position correction, the effect of positioning by clamped groove
Fruit, avoid LED lamp in process of production because the machining accuracy of conventional brace position portion deficiency due to cause LED lamp movement from
And damage is generated, and silica gel material manufacturing cost is low, more easily processes, and is conducive to the production of enterprise.Currently, due to LED moulds
It can be connect with babinet by the way of welding copper stud on block, the accuracy of copper stud welding position also becomes display screen installation effect
One of deciding factor of fruit.But existing welding fixture cannot be completely fixed copper stud, add since there are mismachining tolerances
Existing welding fixture is fixed to copper stud hole position size, and pilot pin and copper stud have mismachining tolerance, the copper in welding
Stud will produce shaking phenomenon.
Utility model content
For the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a kind of welderings of LED display module
Welding fixture.It has the characteristics that simple in structure, accurate positioning, using efficient and convenient and safe and reliable.It can not be by each
Copper stud dimensional tolerance influences, and copper stud is accurately positioned in printed board, so as to avoid the copper stud generation rolling in welding
The generation of dynamic phenomenon, and then improve production efficiency.
In order to solve the above technical problems, the utility model provides a kind of LED display module welding fixture.It includes bottom
Seat, printed board and mounting plate, set guide post, plastic buckle and groove on pedestal, and guide post is several, preferably four, modeling
Material buckle preferably two；Printed board is located in groove, and printed board is equipped with copper stud, and copper stud is several, and copper stud
It is sequentially arranged at the corresponding position in printed board；Set on mounting plate spring positioning needle, pilot hole corresponding with guide post and with modeling
Material buckles corresponding button groove, and spring positioning needle is several, and is corresponded with copper stud, tip before spring positioning needle
In the same plane, spring positioning needle is each provided in respective copper stud, and mounting plate fixation is located on pedestal.
The mounting plate is fixed by guide post and plastic buckle.
The mounting plate is by guide post downwards by spring positioning needle tip as in copper stud, and passing through plastic buckle will
Mounting plate is fixed.
The spring positioning needle can vertically move, and spring positioning needle tip is gradient.
The plastic buckle and guide post are fixed on the base preferably by screw.
Compared with prior art, the advantageous effect of the utility model generation is：The weld clip due to the above structure,
The mounting plate of tool is fixed on the base by guide post and plastic buckle.Since spring positioning needle can vertically move, and spring
Positioning needle tip has certain gradient, so even if copper stud has machining tolerance, remains to copper stud being pressed abd fixed on printed board
On, prevent copper stud from generating shaking in the welding process.It has simple in structure, accurate positioning, using efficient and convenient and work
The features such as safe and reliable.It can not be influenced by each copper stud dimensional tolerance, by copper stud, accurately fixation is located in printed board, is kept away
The generation that the copper stud in welding generates shaking phenomenon is exempted from, to improve production efficiency.
Description of the drawings
Fig. 1 is the utility model structural decomposition diagram；
Fig. 2 is the utility model structure combination diagram；
In figure：It is 1 plastic buckle, 2 guide posts, 3 pedestals, 4 spring positioning needles, 5 mounting plates, 6 printed boards, 7 copper studs, 8 recessed
