Abstract
The utility model relates to a printing tray used for LED lamp bars in liquid crystal displays. Embedding grooves in which LED lamp bar printed circuit boards are arranged are distributed on the surface of a synthetic stone tray body; the shape, dimension and depth of the embedding grooves are consistent with the shape, dimension and thickness of the LED lamp bar printed circuit boards; and two ends of each embedding groove are provided with positioning holes and positioning pins which are corresponding to mounting holes at two ends of each LED lamp bar printed circuit board. The number and arrangement position of the embedding grooves distributed on the surface of the tray of the utility model are completely consistent with the number and position of front feeding trays of a solder paste printer, so that solder paste printing precision can be ensured thoroughly; and since the solder paste printing process of a plurality of LED lamp bar printed circuit boards can be accomplished with one-step printing, so that solder paste printing speed can be increased by dozens of times. The printing tray can facilitate batch processing of subsequent processes such as dispensing, surface mounting of LED lamps and reflow soldering. The printing tray of the utility model has the advantages of simple structure and easy processing, and can benefit the improvement of LED lamp bar processing efficiency.
Description
Technical field
The utility model belongs to the carrier of SMT industry, particularly relates to a kind of print tray for liquid crystal display LED lamp bar.
Background technology
The display screen of LED liquid crystal display is made up of LED lamp bar ordered arrangement, along with popularizing of LED liquid crystal display, the liquid crystal display of various different sizes is more and more extensive, and the specification of the LED lamp bar that therefore display screen uses is that length, width and LED lamp quantity are various in style.
So far, SMT industry is all taked single lamp bar work flow, its substance comprises paste solder printing, puts glue, mounts LED lamp and Reflow Soldering, production efficiency, especially paste solder printing speed, precision and quality that obvious single lamp bar work flow has greatly limited the LED of SMT enterprise lamp bar are difficult to ensure.
Summary of the invention
The utility model is to take single lamp bar work flow to limit production efficiency and the very difficult technical problem ensureing of paste solder printing speed, precision and quality in order to solve existing SMT industry, and proposes a kind of print tray for liquid crystal display LED lamp bar.
The utility model is taked following technical scheme for achieving the above object: this print tray comprises synthetic pallet stone body, feature is, synthetic pallet stone body surface is arranged with the caulking groove of inserting respectively LED lamp bar printed circuit board (PCB), described caulking groove shape, dimensions are consistent with shape, the dimensions of LED lamp bar printed circuit board (PCB), the described caulking groove degree of depth and LED lamp bar printed circuit board (PCB) consistency of thickness, described caulking groove two ends are provided with location hole and the alignment pin corresponding with LED lamp bar printed circuit board (PCB) two ends installing hole.
The utility model can also be taked following technical measures:
Described location hole and alignment pin are threaded.
The beneficial effects of the utility model and advantage are: this print tray surface alignment has the caulking groove of inserting respectively LED lamp bar printed circuit board (PCB), arranging of caulking groove quantity, arrangement position is can be completely consistent with quantity, the position of loading plate before used stencil printer, and obviously in the each caulking groove of this print tray, the printing precision of fixing LED lamp bar printed circuit board (PCB) can be fully guaranteed.Because one-step print can complete the paste solder printing operation of many LED lamp bar printed circuit board (PCB)s, therefore paste solder printing speed is the increase of decades of times compared with wall scroll paste solder printing.This print tray completes after paste solder printing operation, is also convenient to a glue, mounts the batch machining of the subsequent handlings such as LED lamp and Reflow Soldering.The utlity model has simple in structure, handling ease and be conducive to improve the outstanding advantages of LED lamp bar working (machining) efficiency.
Brief description of the drawings
Accompanying drawing 1 is example structure schematic diagram.
Mark in figure: 1 synthetic pallet stone body, 2 caulking grooves, 3 location holes, 4 alignment pins.
Embodiment
Further illustrate the utility model below in conjunction with embodiment and accompanying drawing thereof.
As shown in the figure, this print tray comprises synthetic pallet stone body 1, synthetic pallet stone body 1 surface alignment has the caulking groove 2 of inserting respectively LED lamp bar printed circuit board (PCB), described caulking groove shape, dimensions are consistent with shape, the dimensions of LED lamp bar printed circuit board (PCB), the described caulking groove degree of depth and LED lamp bar printed circuit board (PCB) consistency of thickness, described caulking groove two ends are provided with location hole 3 and the alignment pin 4 corresponding with LED lamp bar printed circuit board (PCB) two ends installing hole.
The location hole of embodiment and alignment pin adopt and are threaded, and also can adopt interference fit to connect.
The caulking groove 2 of embodiment is two row's 11 row, and caulking groove 2 should be considered design according to the quantity of loading plate before the size of LED lamp bar printed circuit board (PCB), stencil printer, position Synthesis at quantity and the arrangement position on synthetic pallet stone body 1 surface.
Claims (2)
1. the print tray for liquid crystal display LED lamp bar, comprise synthetic pallet stone body, it is characterized in that: synthetic pallet stone body surface is arranged with the caulking groove of inserting respectively LED lamp bar printed circuit board (PCB), described caulking groove shape, dimensions are consistent with shape, the dimensions of LED lamp bar printed circuit board (PCB), the described caulking groove degree of depth and LED lamp bar printed circuit board (PCB) consistency of thickness, described caulking groove two ends are provided with location hole and the alignment pin corresponding with LED lamp bar printed circuit board (PCB) two ends installing hole.
2. print tray according to claim 1, is characterized in that: described location hole and alignment pin are threaded.
