Abstract
The present invention relates to a kind of guide rail top support mechanism for reflux welding furnace with net belt transport mechanism, comprise bracing frame, connection bracket, roller guiding, support roller, connection wallboard, contiguous block, chain guide, described bracing frame is provided with two, the two ends of roller guiding are connected by connection bracket, described support roller is fixed in roller guiding by connecting wallboard, and described chain guide connects wallboard by contiguous block.Compared with prior art, the present invention has can improve consumer product welding quality, reduces the advantages such as consumer product defect ware rate.
Description
Technical field
The present invention relates to reflow soldering parts, especially relate to a kind of guide rail top support mechanism for reflux welding furnace with net belt transport mechanism.
Background technology
Reflow soldering is for a kind of welding equipment in SMT industry.It can provide automatic and stable heating environment, makes the solder(ing) paste melted by heat in furnace, thus allows electric elements that pcb board mounts in advance and pcb board reliably be combined by soldering alloy.
Reflow soldering has an important chain transfer member, and chain moves in guide-track groove, and pcb board is supported by chain, runs in burner hearth.Due to fire box temperature when reflow soldering works high (can to 400 degrees Celsius), guide rail be long, and front and back end is fixed, middle free wxpansion.Guide rail is drawn by aluminium and forms, and easily bend after being heated, this just needs supporting mechanism.In addition, guide rail import and export part mobile time, mid portion also will along with synchronizing moving, otherwise intermediate rail can delayed, and bend, pcb board can fall down from chain, burns out circuit board, and this will ask guide rail support mechanism can be servo-actuated.Partial reflux brazier can with net belt transport mechanism, the pcb board fallen down can be sent out, but traditional guide rail support mechanism (supporting mechanism and guipure are interfered) like this just can not be installed, so need for a kind of novel guide rail support mechanism of reflow soldering design with net belt transport mechanism.
Summary of the invention
Object of the present invention is exactly provide one can improve consumer product welding quality to overcome defect that above-mentioned prior art exists, reduces the guide rail top support mechanism for reflux welding furnace with net belt transport mechanism of consumer product defect ware rate.
Object of the present invention can be achieved through the following technical solutions: a kind of guide rail top support mechanism for reflux welding furnace with net belt transport mechanism, it is characterized in that, comprise bracing frame, connection bracket, roller guiding, support roller, connection wallboard, contiguous block, chain guide, described bracing frame is provided with two, the two ends of roller guiding are connected by connection bracket, described support roller is fixed in roller guiding by connecting wallboard, and described chain guide connects wallboard by contiguous block.
Described roller guiding one end is screwed in connection bracket, and other end plug is played screw and is fixed in connection bracket.
Described roller guiding one end is provided with adjustment screw, the upper-lower height of adjusting chain guide rail.
Described bracing frame is fixed on the wallboard at two ends.
Compared with prior art, the present invention can not the drawback of mounting guide rail supporting mechanism by solving in the mode of suspention the reflow soldering that transmits with guipure at the top of guide rail in the past, greatly reduce the pcb board caused due to guide rail temperature distortion to drop the quantity on guipure, improve consumer product welding quality, reduce the defect ware rate of consumer product, thus improve the economic benefit of client.
Accompanying drawing explanation
Fig. 1 is the structural representation of mechanism of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of guide rail top support mechanism for reflux welding furnace with net belt transport mechanism, comprise bracing frame 1, connection bracket 2, roller guiding 3, support roller 4, connect wallboard 5, contiguous block 6, chain guide 7, described bracing frame 1 is provided with two, the two ends of roller guiding 3 are connected by connection bracket 2, roller guiding 3 one end is screwed in connection bracket 2, and other end plug is played screw 9 and is fixed in connection bracket 2, and after being heated, this end can free wxpansion.Described support roller 4 is fixed in roller guiding 3 by connecting wallboard 5, and described chain guide 7 connects wallboard 5 by contiguous block 6.Support roller 4 can move left and right in roller guiding 3, chain guide 7 is by contiguous block 6 and support roller 4 and to be connected wallboard 5 connected, such chain guide 7 is just suspended in midair by support roller 4 and connection wallboard 5, reduce guide rail flexural deformation after being heated, and can move left and right along with the width adjusting of client's pcb board, roller guiding 3 one end is provided with adjustment screw 8, by screwing adjustment screw 8, the height of up-down adjustment chain guide 7 can also adapt to the PCB product of differing heights.From rail crown with suspension type support chains guide rail, thus avoid with guide rail bottom the interference of guipure.
