Description
Technical field
The utility model relates to field of laser processing, particularly relates to a kind of hold down gag of laser plastic welding.
Background technology
The most frequently used laser weld form is called as the laser-transmitting welding.The process of this technology is as follows:
At first two plastic items to be welded are clipped together, then with the laser orientation in a branch of short-wave infrared district to treating bonding position.Laser beam sees through the upper strata transparent material, is absorbed by subsurface material then.Laser energy is absorbed and makes the subsurface material temperature raise, the plastics of fusing the upper and lower.Upper layer of material must guarantee that enough laser passes through.
Usually the plastics Laser Welding is connected to the welding of sequence type contour, welding synchronously and three kinds of welding manners of accurate welding synchronously.Wherein, the sequence type contour is welded as: laser moves and makes its fusing along the outline line of Plastic Welding layer, and plastic layer is connected together at the station gradually; Perhaps will be moved the purpose that reaches welding along fixing laser beam by interlayer.Yet in actual mechanical process, plastic items to be welded is usually can be bonding insecure and cause Lou weldering; When this situation occurring, need the arrestment operation, send the special messenger to revise, cause inefficiency; Need the complete trails of welding be compressed, increased anchor clamps quantity, increased cost.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, and a kind of hold down gag of laser plastic welding is provided, and it is had guarantee that working of plastics to be welded is bonding firmly, avoids Lou weldering, equipment operating efficiency height, belt-tightening characteristics.
The technical scheme of the hold down gag of the laser plastic welding that the utility model provides is such: a kind of hold down gag of laser plastic welding, comprise mobile head, holder, laser head and can be around the slewing equipment of its central axis rotation, the central axes of described laser head optical axis and slewing equipment also can be done and move up and down, described slewing equipment is made of bearing one, bearing two and rotary sleeve, bearing one is set in the rotary sleeve lateral surface respectively with bearing two, and holder is by bearing one, bearing two and rotary sleeve interference fit; The hold down gag of described laser plastic welding also comprises elastic pressuring clamping device, described elastic pressuring clamping device is fixed on the rotary sleeve and can rotates with rotary sleeve, when the welding hot spot when the path of setting moves forward, elastic pressuring clamping device is in the dead astern of solder joint all the time.
In the hold down gag of laser plastic welding of the present utility model, described elastic pressuring clamping device is made of spring guide, spring, guide pin bushing, bearing pin and depression bar, wherein guide pin bushing is fixedlyed connected with slewing equipment, spring guide, spring, the depression bar guide pin bushing endoporus of packing into successively, spring guide inserts the spring endoporus from the spring upper end, the spring lower end is connected with depression bar by bearing pin, bearing pin insert from the depression bar side strut kong and with the strut kong interference fit.
The hold down gag of the laser plastic welding that the utility model is related has following beneficial effect: when carrying out the welding of sequence type contour, solved working of plastics to be welded because of the bonding not firm leakage weldering defective that produces; Do not need the control and the manual intervention of assisting; The control system and the equipment that adopt for the variation that adapts to path of welding have been cancelled, save the required time of control, improved welding efficiency, only need use simple positioning tool to carry out the status to soldered plastics simultaneously gets final product, needn't the complete trails of welding be compressed, reduce anchor clamps quantity, reduce expenses.
Description of drawings
Fig. 1 is the schematic diagram of the hold down gag of the utility model laser plastic welding.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.The hold down gag of the laser plastic welding that the utility model is related is described in detail as follows: referring to Fig. 1, the hold down gag of laser plastic welding comprises mobile head 1, holder 2, laser head 3, rotary sleeve 4, bearing 1, bearing 26, spring guide 7, spring 8, guide pin bushing 9, bearing pin 10 and depression bar 11.
Be installed in the central axes of the optical axis of the laser head 3 on the mobile head 1 and rotary sleeve 4 and can do and move up and down, to satisfy the needs that focal length is adjusted.Holder 2 is installed on the mobile head 1, and by bearing 1, bearing 26 and rotary sleeve interference fit.Guide pin bushing 9 is connected with rotary sleeve 4 by screw, pack into the successively endoporus of guide pin bushing 9 of spring guide 7, spring 8 and depression bar 11, spring guide 7 inserts spring 8 endoporus from spring 8 upper ends, spring 8 lower ends are connected with depression bar 11 by bearing pin 10, bearing pin 10 insert from depression bar 11 sides strut kong 12 and with strut kong 12 interference fit, this bearing pin 10 can apply pre-pressing force to spring 8.Rotary sleeve 4, spring guide 7, spring 8, guide pin bushing 9 and depression bar 11 are done as a whole can the rotation around the central axis of rotary sleeve 4.
According to different welding plastic spare 13, adjust the pre-pressing force of spring 8 and the focus of laser, start the hold down gag of laser plastic welding.The hold down gag that mobile head 1 drives the laser plastic welding moves down and compresses welding plastic spare 13, moves forward along the path of setting and welds.The presser feet of depression bar 11 bottoms is subjected to an active force backward, so presser feet is in the dead astern of solder joint all the time, move along with moving of welding hot spot, rotary sleeve 4, spring guide 7, spring 8, guide pin bushing 9 and depression bar 11 are swung around the central axis (being laser beam) of rotary sleeve 4 together, guarantee that the presser feet of depression bar 11 is in the rear of laser facula all the time, and the welding position compressed, the two layers of plastic of welding position is fit together, be convenient to the welding position to the absorption of laser and the conduction of heat, and the plastics after the fusing are in time pushed, guarantee two layers of plastic is up and down closely welded together.
