Abstract

A connection device of swing hose of wet process equipment of printed circuit board (PCB) comprises a joint main body 1, a sleeve 2, an inner liner 3, and a packing nut 4, wherein the connection end of the joint main body 1 has an external thread and inner conical surface; the sleeve 2 can be sleeved by a swing hose 5; the tubular inner liner 3 has an outer conical surface 31 at one end, which has a plurality of axial grooves 32; the packing nut 4 has an inner thread at one end, which is connected with the screw thread of the joint base body, and a protrusive ring 41 at the other end, which is sheathed on the sleeve 2, the TEFLON swing hose with outer corrugation and the inner liner. By fastening with the screw threads and the conical surface, the swing hose has convenient application and firm connection and is prevented from slippage, and the TEFLON material can protect the swing hose from corrosion by strong acid and alkali. Further, the corrugation design facilitates the resistance reduction of the hose in bent state.

Description

A kind of printed circuit board (PCB) wet process equipment swing hose connection device

Technical field

The utility model relates to the jockey of a kind of printed circuit board (PCB) (PCB) wet process equipment swing flexible pipe.

Background technology

The processing procedure of circuit board includes [drying journey] and [wet process], and [wet process] wherein is circuit board needs to touch liquid in processing procedure meaning; For example the visualization unit in developing manufacture process must be sprayed imaging liquid to circuit board, and must spray cleaning fluid to printed circuit board (PCB) in the washing unit.What the flusher in printed circuit board (PCB) (PCB) wet process equipment had need swing back and forth on relatively-stationary rack rail, so between fixing frame and the relative flusher that swings back and forth, to connect by flexible pipe mostly, generally be referred to as to swing flexible pipe in the industry.The swing flexible pipe that extensively adopts in existing printed circuit board (PCB) (PCB) wet process equipment mainly contains the smooth flexible pipe made from materials such as EPDM, PVC, PP of surfaces externally and internally, the mode that the fixing outstanding mouth of pipe is connected and fixed on swing flexible pipe and the frame be adopt with flexible pipe directly be enclosed within outside the outstanding mouth of pipe, the mode (as Fig. 2, Fig. 3) of banding outside flexible pipe with larynx hoop or trip again.This kind fixed form is locked tight for the smooth hose coupling of the surfaces externally and internally that swings back and forth or is difficult for lock, and owing to flexible pipe is easier to be corroded under the effect of strong acid and strong base liquid medicine or wears out, it is frequent to cause flexible pipe to change number of times, influences production efficiency; Resistance ratios big (as Fig. 4) cause to wave to have some setbacks, thereby the hose coupling place frequently came off when flexible pipe waved under case of bending in addition, influence quality and wasted maintenance time.

The utility model content

The purpose of this utility model, printed circuit board (PCB) (PCB) wet process equipment that just provides the firm difficult drop-off of a kind of locking easy to use is swung hose connection device.

For achieving the above object, printed circuit board (PCB) of the present utility model (PCB) wet process equipment swing hose connection device is characterized in that: comprise the joint matrix, sleeve pipe, neck bush, the packing nut that are fixed on the frame; Described joint matrix interface end is external screw thread, inner conical surface; Described sleeve pipe can in be enclosed within the swing hose port in, it is that male cone (strobilus masculinus) and this port have at least three axial grooves that described tubular liner is overlapped an end, described packing nut one end internal thread is threaded with joint matrix, the other end has bulge loop, is clipped in sleeve pipe (the swing flexible pipe with outer ripple that adopts the TEFLON material to make) and neck bush cover middle.

Earlier the packing nut is backed out during use, to swing and be enclosed within outside the sleeve pipe after flexible pipe passes packing nut, neck bush successively, then the packing nut is screwed into the joint matrix that is fixed on the frame, bulge loop on the packing nut is with the inner conical surface of the male cone (strobilus masculinus) jacking joint matrix of neck bush, because this port of neck bush has axial groove, this port is tightened up tightly to be clipped in the swing flexible pipe outside the sleeve pipe, can not come off thereby flexible pipe is locked on the joint.

The beneficial effects of the utility model are: connect the firm difficult drop-off of locking easy to use because the fastening means that adopts the screw thread clamping and the conical surface to tighten up guarantees to swing flexible pipe; And the swing flexible pipe adopts the TEFLON material, can not produce at strong acid and strong base to be corroded or aging phenomenon; The flexible pipe configuration design becomes corrugated, reduces the resistance when waving under case of bending.

Description of drawings

Fig. 1 is existing swing flexible pipe and joint matrix connected mode structural representation.

Fig. 2 is printed circuit board (PCB) (PCB) the wet process equipment swing hose connection device air knife structural upright schematic diagram of the utility model embodiment.

Fig. 3 is the cross-sectional schematic of Fig. 2.

Among the figure: 1 joint matrix, 2 sleeve pipes, 3 neck bushs, 31 male cone (strobilus masculinus)s, 32 axial grooves, 4 packing nuts, 41 bulge loops, 5 swing flexible pipes.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is existing swing flexible pipe and joint matrix connected mode, adopts flexible pipe directly is enclosed within outer, the mode of banding outside flexible pipe with larynx hoop or trip again of the outstanding mouth of pipe.

Fig. 2 and Fig. 3 are the jockey structure of the utility model embodiment, comprise the joint matrix 1, sleeve pipe 2, neck bush 3, the packing nut 4 that are fixed on the frame; The interface end of joint matrix 1 is external screw thread, inner conical surface; Sleeve pipe 2 can in be enclosed within 5 mouthfuls of the flexible pipes of swing; Neck bush 3 one ends of tubulose are that male cone (strobilus masculinus) 31 and this port have many axial grooves 32; One end internal thread of packing nut 4 is threaded with joint matrix, and the other end has bulge loop 41, and swing flexible pipe with outer ripple and neck bush cover that sleeve pipe 2, employing TEFLON material are made are clipped in middle.

Corresponding to the swing flexible pipe with outer ripple, bushing outer surface, neck bush inner surface also have ripple; Certainly, the inside and outside smooth swing flexible pipe that also can adopt the TEFLON material to make, corresponding bushing outer surface, neck bush inner surface also are smooth.
