Description

Preheating apparatus

Technical field

This utility model is related to a kind of preheating apparatus, more particularly to a kind of can repeatedly heat and cool down the pre- of wiring board Heater.

Background technology

Can wiring board in the fabrication process, need test that good property is kept in temperature adverse circumstances jumpy Energy.Especially contracting of the through hole and blind hole on wiring board in high temperature and low temperature rises whether affect wiring board performance.In test Before, wiring board through heating repeatedly and need to be cooled down, to simulate use state.Existing preheating apparatus cannot meet and heat repeatedly And the requirement of cooling, need a dead lift.

Utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide one kind can repeatedly heat and cool down The preheating apparatus of wiring board.

The purpose of this utility model employs the following technical solutions realization：

A kind of preheating apparatus, for heating a wiring board, the preheating apparatus include a heating arrangement, the heating Structure includes a tool and a workbench, and the tool includes an at least mechanical arm and one first heating plate, the mechanical hand Arm is movably installed in first heating plate, and the workbench includes one second heating plate, and the mechanical arm can be relatively described First heating plate moves and captures the wiring board, first heating plate and second heating plate heating and respectively with it is described Wiring board both sides contradict, to heat the wiring board.

Preferably, the tool also includes one first heat block, and first heat block is fixed on first heating plate First heating plate is set to generate heat.

Preferably, an at least mechanical arm also includes an adsorption section, and institute is adsorbed in the adsorption section using vacuum principle Stating wiring board makes the wiring board move along a first direction.

Preferably, the first direction is perpendicular to first heating plate.

Preferably, the workbench includes one second heat block, and second heat block is fixed on second heating plate Second heating plate is set to generate heat.

Preferably, the preheating apparatus also include a refrigeration structure, and the refrigeration structure is that a fan is described to cool down Wiring board.

Compared to existing technology, the beneficial effects of the utility model are：

The heating arrangement of this utility model preheating apparatus adsorbs wiring board by mechanical arm makes wiring board be added by first Hot plate and the second heater plate, by refrigeration structure wiring board is cooled down, and thus wiring board just can enter repeatedly in a station Row heating for multiple times and cooling, make test reliability.

Specific embodiment

Fig. 1 is referred to, a kind of preheating apparatus 100 are used to that a wiring board 200 to be heated and cooled down repeatedly, described pre- Heater 100 includes a refrigeration structure 10 and a heating arrangement 20.In one embodiment, the refrigeration structure 10 is a wind Fan.

The heating arrangement 20 includes a tool 22 and a workbench 24.The tool 22 includes an erecting bed 220, some It is fixed on the mechanical arm 222 of the erecting bed 220, one first heating plate 224 and to fix and first heating plate 224 First heat block 226.Each mechanical arm 222 is movably installed in first heating plate 224.Each mechanical arm 222 include an adsorption section 2220.Some mechanical arms 222 are parallel to each other.Each mechanical arm 222 is approximately perpendicular to First heating plate 224.In one embodiment, first heating plate 224 is made of aluminum.

The workbench 24 includes one second heating plate 240 and one is fixed on the second heating of second heating plate 240 Block 242.Second heating plate 240 is roughly parallel to first heating plate 224.In one embodiment, second heating Plate 240 is made of aluminum.

Please continue to refer to Fig. 2 to Fig. 6, during using the preheating apparatus, comprise the following steps：Step one, by the line Road plate 200 is positioned on the workbench 24；Relatively described first heating plate 224 of step 2, the mechanical arm 222 is towards one One direction movement is capturing the wiring board 200；Step 3, first heating plate 224 are generated heat, the phase of the mechanical arm 222 To first heating plate 224 towards a second direction movement opposite to the first direction, until the side of the wiring board 200 Contradict with first heating plate 224；Step 4, second heating plate 240 heating and the relatively described court of first heating plate 224 The second direction movement with the opposite side of the wiring board 200 until contradict, now the both sides of the wiring board 200 are by described first Heating plate 224 and second heating plate 240 are heated；Step 5, first heating plate 224 and second heating plate 240 Stop heating, second heating plate 240 moves back to original position towards the first direction；Step 6, the phase of the mechanical arm 222 First heating plate 224 is moved towards the first direction, makes the wiring board 200 hanging, the refrigeration structure 10 makes institute State wiring board 200 to lower the temperature.Repeat the above steps, can just make the wiring board 200 heat repeatedly and cool down, and reach wanting before test Ask.

It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of this utility model claim Within the scope of.
