Technical field
The utility model relates to a kind of uplifting device, particularly a kind of uplifting device that is used in SMT (Surface MountedTechnology, surface mounting technology) industry on the screen process press steel mesh support.
Background technology
Screen process press is a kind of common equipment in the SMT industry, and the course of work of screen process press mainly comprises: 1, need print PCB (Printed circuit board, printed circuit board (PCB)) circuit board and be positioned at steel mesh below and fixing; 2, solder(ing) paste is poured on the scraper inboard of steel mesh top, and along with scraper level on steel mesh scrapes, solder(ing) paste is bitten by the porous nickel on the steel mesh and brushed on the pcb board; 3, by cylinder steel mesh support and steel mesh are lifted, take out the PCB circuit board and put into Turnover Box or enter down road paster operation, whole process is finished.Existing this screen process press mostly is cylinder operation when lifting steel mesh support and steel mesh, because cylinder is positioned at steel mesh support below, cylinder rod tilts to be connected the steel mesh support outside, when cylinder rod boosts, the steel mesh that tilts to rise can form the moment displacement on the pcb board surface, the tin cream of pcb board surface pads printing is sustained damage, quality of welding spot and serviceability can't guarantee, particularly along with scientific and technological progress, various sizes are little, what the high pcb board of required precision used increases, distance between each solder joint is very approaching, the steel mesh that tilts to lift is easy to cause the bond pad shapes that just has been completed for printing to connect or lack scolding tin, make PCB when welding, form rosin joint, connect weldering or joint welding phenomenon, had a strong impact on product quality.How to avoid above-mentioned situation to take place, guarantee that effectively the pad printing quality is a problem to be solved in the utility model.
Summary of the invention
In view of above-mentioned deficiency of the prior art, the utility model aims to provide a kind of uplifting device on the screen process press steel mesh support of being used for that can effectively guarantee pad printing quality on the pcb board when lifting the steel mesh support.
The utility model is achieved through the following technical solutions:
A kind of uplifting device that is used on the screen process press steel mesh support, comprise cylinder, cylinder is fixed on the workbench of steel mesh support below, cylinder cylinder bar tilts to be connected the side of steel mesh support, also comprise a pair of stripper apparatus, stripper apparatus is fixed on the workbench of two drift angle belows of steel mesh support front end, and the upper end of stripper apparatus contacts with the bottom surface of steel mesh support.
Described stripper apparatus is four, and four stripper apparatus lay respectively on the workbench of four drift angle belows of steel mesh support.
Described stripper apparatus comprises demoulding cylinder, supporting plate and abrasionproof pad, demoulding cylinder is fixed on the workbench of steel mesh support drift angle below, supporting plate is connected demoulding cylinder cylinder masthead end, and the abrasionproof pad is located at the supporting plate surface, and the upper surface of abrasionproof pad contacts with steel mesh support bottom surface.
Described stripper apparatus also comprises arrangement for adjusting height, and arrangement for adjusting height is connected between demoulding cylinder cylinder bar and the supporting plate.
Described arrangement for adjusting height comprises sleeve and studs, and sleeve is fixed on the top of demoulding cylinder cylinder bar, and the two ends of studs are connected on sleeve top and the supporting plate bottom surface.
A kind of uplifting device that is used on the screen process press steel mesh support described in the utility model; utilize stripper apparatus to make the steel mesh support before inclination is lifted; earlier carry out vertically lifting of small distance in the vertical direction of PCB circuit board surface; when having avoided directly lifting by cylinder before; in the slight mobile scratching of PCB circuit board surface; cause bond pad shapes connection or tin cream to lack; when welding, form rosin joint; connect weldering and joint welding phenomenon; effectively protected PCB circuit board surface pad printing quality; PCB circuit board welding quality and product quality have been guaranteed; simultaneously; also can be according to actual needs; the bearing height of corresponding adjustment stripping tank bar is to adapt to the serigraphy requirement of different-thickness pcb board.Its overall structure is simple, easy to use, and demolding performace is good.
Description of drawings
Fig. 1 is a partial structurtes cut-away view of the present utility model.
The specific embodiment
Be further described below in conjunction with 1 pair of the utility model of accompanying drawing:
A kind of uplifting device that is used on the screen process press steel mesh support described in the utility model comprises cylinder 10 and two stripper apparatus, and wherein cylinder 10 is fixed on the workbench of steel mesh support 1 below, and cylinder cylinder bar tilts to be connected the side of steel mesh support 1.Stripper apparatus comprises demoulding cylinder 6, sleeve 5, studs 8, supporting plate 4 and abrasionproof pad 3; two demoulding cylinders are separately fixed on the workbench of two drift angle belows of steel mesh support 1 front end; sleeve 5 is fixed on the top of demoulding cylinder cylinder bar by dog screw 7; the two ends of studs 8 are connected on sleeve 5 tops and supporting plate 4 bottom surfaces by screw thread; abrasionproof pad 3 is bonded at supporting plate 4 surfaces; the upper surface of abrasionproof pad 3 contacts with steel mesh support 1 bottom surface; abrasionproof pad 3 can be protected the bottom surface of steel mesh support 1, guarantees that simultaneously steady, the safety of the process of lifting is carried out.Certainly stripper apparatus also can be four, and four stripper apparatus are separately fixed on the workbench of 1 four drift angle belows of steel mesh support, and four stripper apparatus can start steel mesh support 1 simultaneously in vertical direction from the 9 surface disengagings of PCB circuit board.And the bearing height of stripper apparatus also can be realized by adjusting studs 8 at any time.
In the time of need lifting steel mesh support 1 in the operating process; at first start two stripper apparatus; the cylinder bar of two demoulding cylinders 6 stretches out simultaneously; because the cylinder bar is vertical mutually with steel mesh support 1; supporting plate 4 can vertically lift steel mesh support 1 from PCB circuit board 9 surfaces under the protection of abrasionproof pad 3 smoothly; steel mesh 2 is broken away from from the PCB circuit board that just has been completed for printing 9 surfaces, and the solder joint that the separation process that can not take place to tilt before causes connect weldering or joint welding phenomenon.Then, the cylinder 10 that is connected steel mesh support 1 side is started working, and cylinder cylinder bar lifts steel mesh support 1 fully, thus finish whole steel mesh 2 the demoulding, lift process.
