Abstract
The utility model relates to the technical field of wave soldering in an electronic industry, in particular to a preheating equipment for preheating to a circuit board which is surface mounted with an electronic components in a wave soldering machine. The preheating equipment comprises a plurality of paratactic preheating boxes and corresponding preheating covers which are respectively arranged on the upper end and the lower end of two parallel guide ways, wherein a preheating zone is formed between the preheating box and the preheating cover, and the preheating box is a hollow box with upper end inlet, wherein an impeller driven by a motor is arranged in the box, and the upper end face of the preheating box is covered with a porous ventilation plate, and a plurality of heating pipes is arranged between the ventilation plate and the preheating box. Because the impeller of the utility model in the preheating box can let the thermal energy, which is produced by the heating pipe, is capable of forming a well-distributed thermal wind fetch, thereby reducing the temperature regional unbalance and the control instability, improving the preheating effect, guaranteeing the subsequent welding quality.
Description
Technical field:
The utility model relates to the wave-soldering technical field of electron trade, refers in particular to the preheating device that is used for the circuit board behind the surface mounted electronic element is carried out preheating in the crest welder.
Background technology:
In electron trade, often need carry out wave-soldering, so that electronic component is fixed on the circuit board to the circuit board behind the surface mounted electronic element.Because the temperature when carrying out wave-soldering higher (being about 250 degree) as circuit board not being carried out the preheating of a period of time, will cause circuit board to be scrapped because of distortion during welding.At present, preheating device in the crest welder mainly is to be made of two parallel guide rails and the preheating cover and the preheating cabinet that are arranged on the guide rail upper and lower, the circuit board that electronic component is arranged and scribble rosin when surface mount is along guide rail during by the preheating cabinet top, the red infrared illumination light evolution of heat under the control of computer that is arranged in the preheating cabinet is carried out preheating to circuit board, one excites the activity of rosin, thereby assurance welding quality, secondly, preheating also can make circuit board have certain initial temperature before carrying out weld job, thereby is unlikely to cause circuit board to be out of shape because of variations in temperature is excessive when welding.But in the production practices process, people also find, because the red infrared illumination light in the preheating cabinet carries out work in the mode of flicker, has certain temperature difference when it is lighted and when extinguishing, that is to say to produce certain temperature fluctuation that this just causes the heat distribution in the preheating zone between preheating cabinet and the preheating cover inhomogeneous.When circuit board passed through the preheating zone, the rosin activity that diverse location place is excited on it had certain difference, thereby makes that the welding quality of circuit board each point is inconsistent.
Summary of the invention:
The purpose of this utility model provides a kind of uniform heat distribution with regard to being at the weak point that has the wave-soldering preheating device now, thereby can make the circuit board that enters the preheating zone obtain the preheating device that steady temperature rise guarantees the welding quality of the follow-up wave-soldering that carries out.
For achieving the above object, the utility model comprises: a plurality of preheating cabinets arranged side by side and corresponding a plurality of preheating cover, preheating cabinet and preheating cover are individually fixed in the upper and lower side of two parallel guide rails, form the preheating zone between preheating cabinet and the preheating cover, described preheating cabinet is the hollow box of upper end open, be provided with the impeller by driven by motor in it, the ventilative board of porous is stamped in the upper surface of preheating cabinet, is provided with some heat-generating pipes between ventilative board and preheating cabinet.
As a kind of improvement of technique scheme, described heat-generating pipe is connected with computer and regulates its power output of control by computer PID.
After adopting technique scheme, because the heat energy that the impeller in the utility model preheating cabinet can make heat-generating pipe produce forms the hot blast district that is evenly distributed all around, thereby reduce the regional disequilibrium of temperature and the unsteadiness of control, improve pre-heat effect, guarantee follow-up welding quality.

Accompanying drawing 2 is the perspective view of preheating cabinet
Accompanying drawing 3 is the perspective exploded view of accompanying drawing 2
Embodiment:
See shown in the accompanying drawing 1～3, the utility model comprises a plurality of preheating cabinets arranged side by side 10 and corresponding a plurality of preheating cover 20, preheating cabinet 10 and preheating cover 20 are individually fixed in the upper and lower side of two parallel guide rails 30, and preheating cover 20 is provided with handle 21 and checks situation in the preheating cabinet 10 to be easy to open preheating cover 20.Form preheating zone 40 between preheating cabinet 10 and the preheating cover 20, described preheating cabinet 10 is the hollow box of upper end open, be provided with the impeller 60 that drives by motor 50 in it, the ventilative board 70 of porous is stamped in the upper surface of preheating cabinet 10, is provided with some heat-generating pipes 80 between ventilative board 70 and preheating cabinet 10.
Described heat-generating pipe 80 is connected with computer and regulates its power output of control by computer PID.
When surface mount has the circuit board of electronic component to pass through preheating zone 40 along guide rail 30, motor 50 impeller 60 are rotated, form the air of convection current, the spread heat that heat-generating pipe 80 is sent arrives whole preheating zone 40, because preheating zone 40 is in the state of relative closure, therefore, heat distributing very evenly in preheating zone 40, can obtain temperature rise stably after in circuit board enters preheating zone 40, the rosin activity on it also can be excited equably, thereby guarantees the welding quality of follow-up wave-soldering.
