Description
The utility model relates to wave-soldering unit, and specifically a kind of head is by manual wave-soldering unit.
Existing wave-soldering unit has two classes substantially, and a class is an association type immersed solder machine, and a class is full-automatic wave-soldering unit.Wherein the former welding quality is low, and labor strength is big, and productivity ratio is low, the subject matter that the latter exists be cost than higher, one-time investment is bigger.
The purpose of this utility model is a kind of can reducing cost of design, higher welding quality is arranged again, and can alleviate the semi-automatic wave-soldering unit of labor strength.
Its main technical schemes comprises rack-mounted guide rail and the head that can move on guide rail, the left side of guide rail, right two ends are respectively the clamping station and unload plate, the cooling station, the middle part is followed successively by the scaling powder application station from left to right, preheating station and welding post, and the scaling powder applying device is installed respectively on the station of correspondence, preheating device and welder, the running roller that can slide is installed in bottom at head on guide rail, circuit plate holder pawl is installed in head, the lower end of this jaw is stretched out the head side-lower respectively, jaw Height Adjustment button is installed on head, so that regulate wiring board to scaling powder liquid level and molten tin liquor height together, improve welding quality, jaw width adjustment button is installed, so that make jaw can adapt to the wiring board of various different in width in the head side; In the scaling powder applying device, flux bath is installed in the guide rail below, and the scaling powder spout is positioned at flux bath and points to wiring board, in the bottom surface of flux bath the feed liquor valve is installed, so that scaling powder is provided in groove; In the welder, tin melting slot is installed in the below of guide rail, heating tube, molten tin spout and molten tin pump are installed in tin melting slot, the tin pump motor is installed above the side of guide rail, the tin pump shaft of molten tin pump utilizes belt to connect with the tin pump motor, there is case outside at tin pump motor and tin pump shaft, unloading plate, cooling fan is installed in the guide rail below of cooling station correspondence, so that to just through the cooling of drying of the wiring board of high-temperature soldering, after the cooling, with regard to desirable wiring board down.
The utility model has the advantages that 1, compare with manual welding, molten tin can produce packing phenomenon during because of manual welding around solder joint under the effect of gravity, form rosin joint easily, and this machine adopts wave soldering technology, it is molten that tin is bottom-up gushs, can not produce to pile up and cause rosin joint, if, be convenient to check and take its corresponding measures yet because of the severe oxidation of components and parts pin or pad produces Lou weldering.Therefore, the qualification rate of wiring board, reliability improves greatly; Simultaneously, manual welding is the welding of single solder joint, and labor strength is big, and productivity ratio is low, and solder joint is subjected to artificial factor many, and consistency is poor, and this machine welds the solder joint of monoblock wiring board simultaneously, productivity ratio height, and solder joint uniformity, neat appearance; 2, compare with traditional association type immersed solder machine, this machine adopts spout foaming type scaling powder spraying, and the scaling powder coating is even, and scaling powder can not overflow to the wiring board front, the PCB surface cleaning, and the consumption and the volatilizing loss of scaling powder are little.The movement locus of association type immersed solder machine is manually operated curvilinear motion, and the motion of this machine is a rectilinear motion, and is therefore simple to operate, the productivity ratio height, and labor strength is low.The molten tin surfaces of association type immersed solder machine is static, and its surperficial oxide layer is bigger to the influence of welding quality, and this machine adopts wave soldering technology, what contact with the wiring board solder joint is the fresh molten tin of gushing out all the time, the influence of non-oxidation layer, therefore, the welding quality height.3, compare with traditional full-automatic wave-soldering unit, this machine makes the automatic transmission of wiring board into artificial transmission, has then kept remaining necessary function, thus simple in structure, low, the small investment of cost.
Fig. 1 is a structure chart of the present utility model.
As shown in the figure: mounting guide rail 6 on frame 7, are being followed successively by the clamping station 1 that wiring board is placed on the head 13 on the guide rail 6 from left to right, scaling powder application station 2, preheating station 3, welding post 4 and unload plate cooling station 5.
Infrared hot plate 16 is installed in the guide rail below of preheating station correspondence, so that the wiring board to coated scaling powder carries out preheating, tin melting slot 24 is installed below the guide rail 6 of welding post correspondence, bottom in groove is installed and is used to heat scolding tin, make it to be the heating tube 19 of molten condition, molten tin spout 21 and tin pump 23 are installed in middle part in tin melting slot, this spout is identical with my the described structure of ZL93237293.7 patent of application with the tin pump structure, tin pump motor 17 is installed above the side of frame, the tin pump shaft 22 of molten tin pump 23 utilizes belt 18 to connect with motor 17, in the tin pump motor 17 and the outside of tin pump shaft 22 case 27 is installed.Below the guide rail that unloads plate cooling station correspondence, cooling fan 25 is installed.
The running roller 15 that installation can be moved on guide rail below head 13,4 wiring board jaws 11 are installed in head symmetrically, the side-lower of head is stretched out in the bottom of each jaw, the middle part be hinged on respectively with adjust the support that button 12,14 connects on, the two ends of support are positioned at the slide block of band cannelure, slide block is positioned at the transverse groove of the side plate of head both sides, can make jaw do laterally or vertically move under the drive of adjusting button 12,14, to adjust width or height.On the top of head 3 jaw Height Adjustment buttons 12 are installed, jaw width adjustment button 14 is installed in the head side, when needing to adjust the height of jaw or width, rotation is adjusted button 12,14 and is got final product respectively.
During work, earlier in the clamping station inserts wiring board to be welded wiring board jaw in the head, head is moved past the scaling powder application station, at this moment, the scaling powder foam is through bottom surface and the components and parts pin surface of spout automatic coating in wiring board to be welded.Continuation moves to head on the preheating station, stay for some time, make infrared hot plate with wiring board and accompanying scaling powder heating, the temperature of wiring board is increased to about 120 ℃, molten tin is to the thermal shock of wiring board when welding to reduce, the thermal deformation of welding rear board is reduced, simultaneously, make scaling powder reach the activation point of molecule, improve the wettability that helps weldering effect and solder joint, welding quality is improved, then, again head is slowly moved past welding post, at this moment, impeller in the tin pump will melt tin to be extracted out from the bottom of tin melting slot, is gushed out by molten Xi Penkouchu through passage, and contacts with the surface of wiring board bottom surface and components and parts pin, make solder joint to be welded and components and parts pin go up tin and soldering equably, unnecessary molten tin is because the effect of gravity comes back in the tin melting slot, and through behind the welding post, the welding job of wiring board is just finished.Continuation moves to head and unloads plate, and the cooling station such as cools off at back work.
