The mechanism comprises a rack (1), a net belt shaft (2) and a drive shaft (7), wherein the net belt shaft (2) and the drive shaft (7) are arranged on the rack (1); net belt chain wheels (3) are arranged on the net belt shaft (2); two overrun clutches which are opposite in direction, namely a first overrun clutch (4A) and a second overrun clutch (4B), are arranged on the drive shaft (7); drive chain wheels (10) are also arranged on the drive shaft (7); a high-speed motor (9) and a low-speed motor (13) which are opposite in direction are also arranged on the rack (1); and an overload protection clutch (14) is arranged at the end of the low-speed motor (13). Compared with the prior art, the mechanism has the advantages of compact structure, stability and reliability in working, capability of batch processing and the like.
Description
Technical field
The present invention relates to reflow soldering parts, especially relate to a kind of reflow soldering mechanism that carries out high low speed switching by freewheel clutch.
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, thereby allows the electric elements and the pcb board that mount in advance on pcb board combine reliably by soldering alloy.
Pcb board is by guipure (or chain) transmission, with direct current or alternating current motor transmission.The normal speed adjustable range of d.c. motor own is generally less than 5.If customer requirement guipure (or chain) slewing range exceedes 5, be convenient to process different pcb board welding, can only select and exchange extraordinary variable speed electric motors, particularly, utilize frequency converter timing.
Use Frequency Converter Control alternating current motor, expensive.
Summary of the invention
Object of the present invention is exactly to provide a kind of compact conformation in order to overcome the defect that above-mentioned prior art exists, and working stability is reliable, the reflow soldering mechanism that carries out high low speed switching by freewheel clutch that can batch process.
Object of the present invention can be achieved through the following technical solutions: a kind of reflow soldering mechanism that carries out high low speed switching by freewheel clutch, it is characterized in that, comprise frame 1, be arranged on guipure axle 2 and driving shaft 7 in frame 1, guipure axle 2 is provided with guipure sprocket wheel 3, driving shaft 7 is provided with two freewheel clutches of opposite direction: the first freewheel clutch 4A and the second freewheel clutch 4B, on driving shaft 7, be also provided with drive sprocket 10, in described frame 1, be also provided with high-speed motor 9 and the zero motor 13 of opposite direction, zero motor 13 ends are provided with overload protection clutches 14.
Described guipure axle 2 two ends are by flange bearing 6 connection frames 1.
Described driving shaft 7 two ends are respectively by flange bearing and clutch shaft bearing installing plate 5 and the second bearing installing plate 16 connection frames 1.
Described drive sprocket 10 is by chain connection network belt sprocket 3.
Described high-speed motor 9 connects the first freewheel clutch 4A by chain.
Described zero motor 13 connects the second freewheel clutch 4B by chain.
Compared with prior art, the present invention now utilizes 2 freewheel clutches, and high low speed d.c. motor is realized to online switching, efficient and convenient.When use, as long as stir change-over switch, just can realize the switching of guipure high velocity and low regime.Meanwhile, utilize the slewing range of d.c. motor itself, maximum can realize 5X5=25 slewing range doubly in theory, has greatly improved the disposal ability of reflow soldering.In practical application, d.c. motor is cheaply reliable, adapts to SMT industry operation characteristic, has greatly saved cost.
Brief description of the drawings
Fig. 1 is the structural representation of mechanism of the present invention;
Fig. 2 is the side view 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 Fig. 1～2, a kind of reflow soldering mechanism that carries out high low speed switching by freewheel clutch, comprise frame 1, be arranged on guipure axle 2 and driving shaft 7 in frame 1, guipure axle 2 two ends are by flange bearing 6 connection frames 1, driving shaft 7 two ends are respectively by flange bearing and clutch shaft bearing installing plate 5 and the second bearing installing plate 16 connection frames 1, guipure axle 2 is provided with guipure sprocket wheel 3, driving shaft 7 is provided with two freewheel clutches of opposite direction: the first freewheel clutch 4A and the second freewheel clutch 4B, on driving shaft 7, be also provided with drive sprocket 10, drive sprocket 10 is by chain connection network belt sprocket 3, in described frame 1, be also provided with high-speed motor 9 and the zero motor 13 of opposite direction, high-speed motor 9 connects the first freewheel clutch 4A by chain, zero motor 13 connects the second freewheel clutch 4B by chain, zero motor 13 ends are provided with overload protection clutches 14.
When speed end work, zero motor 13 stalls, high-speed motor 9 rotates counterclockwise (Fig. 1 sees from front to back), by chain-driving the first freewheel clutch 4A (speed end) pin rotation counterclockwise, the first freewheel clutch 4A is due to fixing with driving shaft 7, driving shaft 7 rotates counterclockwise, and on it, drive sprocket 10 also rotates counterclockwise, and drive sprocket 10 rotates counterclockwise by chain-driving guipure sprocket wheel 3; Guipure axle 2 drives guipure motion, sends pcb board to burner hearth.Now, low speed end the second freewheel clutch 4B makes oppositely (Fig. 1 sees it is to clockwise rotate from back to front) skid.
In the time being switched to low speed, high-speed motor 9 stalls, zero motor 13 startups rotate counterclockwise (Fig. 1 sees from front to back), rotate counterclockwise by chain-driving the second freewheel clutch 4B (low speed end), drive sprocket 10 is due to fixing with guipure axle 2, also rotate counterclockwise, drive sprocket 10 rotates counterclockwise by chain-driving guipure sprocket wheel 3 (guipure axle 2), thereby realizes outwards (from right to left) motion of guipure.Now, speed end the second freewheel clutch 4 skids.
