Abstract
The utility model provides a product capable of effectively controlling the soldering height of a component in wave soldering, in particular to a soldering fixed cover. The fixed cover (1) is a hard board with four location holes (4) at four corners of an edge. Fixed thimbles (2) and fixed propping strips (3) with uncertain amounts are installed on the fixed cover (1), the amounts, positions and lengths of the fixed thimbles (2) and the fixed propping strips (3) are set according to the requirement details of each component to be welded, and each fixed thimble (2) and each fixed propping strip (3) are required to just completely contact each other and fix each component to be welded. When in wave soldering, the fixed cover (1) ensures that the component to be welded and a PCB (Printed Circuit Board) are in a relative rest state so that the soldering height of the welded component is accurately controlled.
Description
Technical field
The utility model relates to a kind of components and parts of controlling parts welding and assembling height, belongs to the wave soldering field.
Background technology
In wave soldering, all need to use wave-soldering to cross furnace tool.Significant feature is:
1, at high temperature, some pcb boards are owing to the reason meeting temperature distortion of sheet material, and wave-soldering is crossed the effect that furnace tool plays the carriage protection, prevents the curved substrate distortion;
2, protection pcb board bottom surface has been crossed the SMT components and parts of Reflow Soldering, masks the position of these components and parts in the design of tool, accomplishes local welding targetedly, i.e. the selectivity wave-soldering;
3, prevent that Xi Shui from overflowing and destroy product.
The conventional wave-soldering that uses is crossed the welding quality requirement that furnace tool can satisfy common product, but requires for the welding quality of automobile electronics, and new problem has just occurred.Because in the process of wave soldering, components and parts can be subjected to the influence of the factors such as shake of impulse force and chain, easily cause welding back components and parts come-up, the welding and assembling height of components and parts can not be controlled accurately, can't reach the quality requirement of initial design.
The utility model content
During for the solution wave soldering, the problem that the welding and assembling height of components and parts can not be controlled accurately, the utility model provides a kind of welding fixed cap of effectively controlling parts welding and assembling height.Fixed cap is a plastics hardboard, respectively there is a location hole at four angles, edge, the indefinite fixedly thimble of quantity is housed on fixed cap, and these fixedly the length of quantity, position and the thimble of thimble be that the specific requirement of the welding component that is fixed according to each needs is set, require each thimble just in time to contact fully and fix each components and parts that needs welding.For accurate fixed length stripe shape components and parts or a plurality of identical side by side components and parts, can also be provided with fixedly top bar of a plurality of long strip types on the fixed cap in addition.Equally, fixedly the components and parts that are fixed as required of the quantity of top bar, position and length are set.According to the difference of tool, a block welding fixed cap can be fixed one or more pcb board simultaneously.
During application, on original tool, increase a fixed cap, in advance determine fixedly thimble and fixedly quantity, position and the length of top bar on the fixed cap according to the concrete condition of the components and parts on the welded plate, after finishing the plug-in unit operation, lid is fixed cap down, and pin the snap close on fixed cap both sides, make each thimble can contact and fix each components and parts that need weld fully.During wave soldering, this fixed cap makes soldered components and parts and pcb board be in a kind of relative static state, is controlled accurately with the welding and assembling height that guarantees welding back components and parts.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the front view of the utility model fixed cap.
Fig. 2 is the vertical view of the utility model fixed cap.
Embodiment
Shanghai worker 4489001 pcb boards are put into the wave-soldering anchor clamps; confirm that jig pallet puts the paster components and parts covering that needs protection in place; carry out plug-in unit; after guaranteeing that each components and parts is inserted into the position; with the pilot pin on four location holes, the 4 line-up jig pallets on the fixed cap 1, and fixed cap 1 pinned, make that each thimble 2 and the fixing top bar 3 on the fixed cap 1 fully contacts with components and parts on the pcb board; components and parts on the pcb board are fixed on the height of wanting, then jig pallet are sent into wave-soldering furnace.This fixed cap makes that finally the welding and assembling height that welds the components and parts on the pcb board of back is controlled accurately.
Claims (3)
1. during a wave soldering, the fixed cap of controlling parts welding and assembling height, it is characterized in that: the utility model fixed cap is the hardboard (1) that respectively there is a location hole (4) at four angles, an edge, the indefinite fixedly thimble (2) of quantity is housed on fixed cap, and these fixedly the length of quantity, position and the thimble of thimble (2) be to set according to the specific requirement of each welding component, when requiring welding, each thimble just in time contacts and fixes each components and parts that needs welding fully.
2. fixed cap according to claim 1, it is characterized in that: for accurate fixed length stripe shape element, can also be provided with fixedly top bar (3) of a plurality of long strip types on the fixed cap, the element that the quantity of top bar, position and length are fixed is as required set, when requiring welding, each fixedly the top bar just in time contact and fix each components and parts that needs welding fully.
3. fixed cap according to claim 1 is characterized in that: a fixed cap can be fixed one or more PCB according to the difference of tool.
