It is kind by pump function, so that the liquid solder surface of melting is formed the solder wave of specific shape, when the dress for having inserted component
When connection component passes through solder wave at a certain angle, the technology of solder joint is formed in pin-land.Component is by chain conveyor
During transmission, elder generation is preheated in welding machine preheating zone, and (component preheating and its temperature to be achieved are still by scheduled temperature
It writes music line traffic control).In actual welding, the preheating temperature in control assembly face is usually also wanted, therefore much equipment both increase accordingly
Temperature-detecting device.After preheating, component is welded by solder wave.Specifically: molten tin bath fills the liquid solder of melting, steel
Molten butt-joint material is drawn up the wave of setting shape by trench bottom nozzle, in this way, when components welding face passes through wave just by solder Wave heating, together
When solder wave also just wetting welding zone and be extended filling, realization welding process eventually.Existing wave-soldering furnace lacks in molten tin bath
Tin amount monitoring, only by human visual observation, inevitably there is the case where tin amount deficiency still works, cause bad production.
The spirit that the applicant adheres to research and innovation, keeps on improving thus develops a kind of symbol using professional eye and professional knowledge
The tin amount for the wave-soldering furnace that conjunction industry utilizes detects alarm structure, i.e. proposition this case application.
Summary of the invention
The purpose of this utility model is to provide a kind of tin amounts of wave-soldering furnace to detect alarm structure, examines automatically to tin amount
It surveys, accurate warning note and control reduce bad production, and structure is simple, compact, meet industry utilization.
In order to achieve the above objectives, the utility model adopts the following technical solution:
A kind of tin amount detection alarm structure of wave-soldering furnace, includes furnace body, furnace body has feeding end and discharge end, in furnace
Body is equipped with the guide rail between the feeding end and discharge end of bridging furnace body, and two transmission chain claws respectively correspond and are assembled in leading for furnace body
On rail, chain claw loopy moving between the feeding end and discharge end of furnace body is transmitted；The feeding of transmission chain claw is carried in the furnace body
Direction is sequentially distributed Welding compound spraying coater, preheating device, Wave-soldering device and cooling device；The Wave-soldering device has branch
Frame and the molten tin bath being arranged on bracket, the liquid solder surface of molten tin bath form the solder wave of specific shape；Molten tin bath passes through motor silk
Linkage drives and opposite bracket is gone up and down；Floating ball is equipped in molten tin bath, floating ball is suspended on one end of lever, the other end connection of lever
Sensing chip, sensing chip collocation optical flame detector work is arranged in the lower end for drawing bar up and down in the upper end for drawing bar up and down, and optical flame detector connects wave crest
The control system of brazier.
The utility model is designed by resulting structure, using the connection of floating ball and optical flame detector, is detected automatically to tin amount, in time
Accurate warning note and control, reduce bad production, save material and cost.Structure is simple, compact, significant increase wave-soldering
The operation ratio and operability of furnace meet industry utilization.
Detailed description of the invention:
Attached drawing 1 is the preferred embodiment structural schematic diagram of the utility model；
Attached drawing 2 is the partial structurtes schematic side view of Fig. 1 embodiment；
Attached drawing 3 is the molten tin bath tin position control structure schematic diagram of Fig. 1 embodiment.
Specific embodiment:
Make furtherly below with reference to technical effect of the attached drawing to the design of the utility model, specific structure and generation
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Refering to fig. 1, shown in 2,3, it includes furnace that the utility model, which detects alarm structure in relation to a kind of tin amount of wave-soldering furnace,
Body 1 and corresponding control system, furnace body 1 have feeding end and discharge end, and the feeding end of bridging furnace body 1 is equipped on furnace body 1 and is gone out
Expect the guide rail 11 between end, two transmission chain claws 2 are respectively corresponded and are assembled on the guide rail 11 of furnace body 1, transmit chain claw 2 in furnace body 1
Feeding end and discharge end between loopy moving.The feed direction that transmission chain claw 2 is carried in the furnace body 1 is sequentially distributed scaling powder
Spray equipment 3, preheating device 4, Wave-soldering device 5 and cooling device 6, structure is relatively simple, connection and reasonable arrangement, good integrity.Institute
The top for stating Welding compound spraying coater 3 is disposed with extractor fan 7, and extractor fan 7 collects outside discharge furnace body the smog of scaling powder,
