Abstract
The invention relates to a guide rail top supporting mechanism for a reflow oven with a mesh belt conveying mechanism. The guide rail top supporting mechanism comprises support frames, connecting brackets, a roller guide rod, supporting rollers, connecting wallboards, connecting blocks and chain guide rails, wherein two support frames are connected to two ends of the roller guide rod through the connecting brackets; the supporting rollers are fixed on the roller guide rod through the connecting wallboards; and the chain guide rails are connected with the connecting wallboards through the connecting blocks. Compared with the prior art, the guide rail top supporting mechanism has the advantages that the welding quality of customer products can be improved, the defective rate of the customer products is reduced, and the like.
Description
Technical field
The present invention relates to reflow soldering and use parts, especially relate to a kind of reflow soldering that has the guipure connecting gear with guide rail top braces mechanism.
Background technology
Reflow soldering is a kind of welding equipment that is used in the SMT industry.It can provide automatic and stable heating environment, makes solder(ing) paste melted by heat in the stove hall, thereby lets the electric elements and the pcb board that mount in advance on the pcb board combine reliably through soldering alloy.
Reflow soldering has an important chain transfer member, and chain moves in guide-track groove, and pcb board is supported by chain, in burner hearth, moves.Because reflow soldering when work fire box temperature high (can to 400 degrees centigrade), guide rail is long, and the front and back end is fixed, middle free wxpansion.Guide rail is drawn by aluminium and forms, and the back that is heated is crooked easily, and this just needs supporting mechanism.In addition, when guide rail was imported and exported part and moved, mid portion also will be along with same moved further, otherwise middle guide rail can lag behind, bending, pcb board can fall down from chain, burns out circuit board, this will differentiate rail supporting mechanism can servo-actuated.The partial reflux brazier can have the guipure connecting gear; Can send out the pcb board that falls down; But traditional rail support mechanism (supporting mechanism and guipure are interfered) like this just can not be installed, so need design a kind of novel rail support mechanism for the reflow soldering that has the guipure connecting gear.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of client's of raising product welding quality to be provided, and the reflow soldering that has the guipure connecting gear that reduces client's product defect ware rate is with guide rail top braces mechanism.
The object of the invention can be realized through following technical scheme: a kind of reflow soldering that has the guipure connecting gear is with guide rail top braces mechanism; It is characterized in that; Comprise bracing frame, connect support, roller guiding, support roller, connection wallboard, contiguous block, chain guide; Described bracing frame is provided with two; Through connecting the two ends that support connects roller guiding, described support roller is fixed on the roller guiding through connecting wallboard, and described chain guide connects wallboard through contiguous block.
Described roller guiding one end is screwed and is connecting on the support, and the other end is played screw with plug and is fixed on the connection support.
Described roller guiding one end is provided with adjustment screw, regulates the height up and down of chain guide.
Described bracing frame is fixed on the wallboard at two ends.
Compared with prior art; The present invention has the drawback that reflow soldering that guipure transmits can not the mounting guide rail supporting mechanism through having solved with the mode of suspention at the top of guide rail in the past; Reduced the pcb board that causes owing to the guide rail temperature distortion quantity on guipure that drops widely; Improve client's product welding quality, reduced the defect ware rate of client's product, thereby improved client's economic benefit.
Description of drawings
Fig. 1 is the structural representation of mechanism of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
As shown in Figure 1; A kind of reflow soldering that has the guipure connecting gear comprises bracing frame 1, connection support 2, roller guiding 3, support roller 4, connects wallboard 5, contiguous block 6, chain guide 7 with guide rail top braces mechanism, and described bracing frame 1 is provided with two; Through connecting the two ends that support 2 connects roller guiding 3; Roller guiding 3 one ends are screwed and are connecting on the support 2, and the other end is played screw 9 with plug and is fixed on the connection support 2, and being heated this end of back can free wxpansion.Described support roller 4 is fixed on the roller guiding 3 through connecting wallboard 5, and described chain guide 7 connects wallboard 5 through contiguous block 6.Support roller 4 can be on roller guiding 3 move left and right; With support roller 4 and is connected wallboard 5 and links to each other, chain guide 7 is with regard to supported roller 4 and connect wallboard 5 suspentions and get up like this through contiguous block 6 for chain guide 7, and the minimizing guide rail is out of shape in the rear curved of being heated; And can be along with the width adjusting of client's pcb board move left and right; Roller guiding 3 one ends are provided with adjustment screw 8, and through screwing adjustment screw 8, height that can also up-down adjustment chain guide 7 adapts to the PCB product of differing heights.From the guide rail top with suspension type support chains guide rail, thereby avoided the interference with the guipure of guide rail bottom.
