Man made crystal diamond following process spray-painting plant
Technical field
The present invention relates to painting applications, relate in particular to a kind of man made crystal diamond following process spray-painting plant.
Background technology
Man made crystal diamond is bright and colourful, is a kind of ornaments of fashion.Current synthetic quartz manufacturing process is main rapid in two steps, Part I is the shape manufacture (semi-finished product) of crystal diamond, main dependence equipment (grinder, polishing machine) is realized by manual operation, automatic or semi-automatic control, second part refers to that half-finished postorder process, its process primarily of cleaning, inhale mould, inspection, clean again, silver-plated, the operation such as to spray paint forms.Adopt artificial pistol to carry out spray painting operation for current much technique of spraying paint, first will silver-plated for the template that crystal diamond is housed good after put on a moving belt, after baking oven baking, walk to water-screen cabinet place sprayed paint by artificial pistol.Publication number a kind of automatic spray apparatus that has been the Introduction To Cn Patent of CN 201632364U, this device is used to spraying reflector layer (silver coating), but can be used for sprayed coating protective layer equally, also has a lot of technology adopting this type of spraying at present.
Artificial hand-held spray gun paint, causes great infringement to healthy; Manual operation has unstability in addition, can not ensure the uniformity of paints and lacquers protection film.Adopt the spraying technology that CN 201632364U introduces, it is the spraying of a kind of swing arm, do swing arm motion around a fixed axis and drive spray gun spraying, the path domain sprayed be one fan-shaped, and streamline is rectilinear motion, the path domain formed is a rectangle, so the two can not overlap with regard to some, the scope exceeded is exactly the region of paint waste, in addition due to fixed axis move in a circle time, drive connecting rod motion by eccentric wheel, the tangential velocity of circle is constant, but the speed projecting to connecting rod one end will vary widely, the speed of swing arm motion is caused also can ceaselessly to change, cause the uneven of spraying, affect the quality of product.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
The overall structure schematic diagram of man made crystal diamond following process spray-painting plant of the present invention as shown in Figure 1, comprise support 10, slide block assembly 14, guide rail 9, the spray gun fixed bar 11 being connected with spray gun and magnetic valve 1, magnetic valve 2, guide rail 9 is fixed on support 10, spray gun fixed bar 11 and slide block assembly 14 are fixedly linked, slide block assembly 14 passes guide rail 9 and is controlled to drive described spray gun fixed bar 11 by magnetic valve 1, magnetic valve 2) move horizontally back and forth along guide rail 9, spray gun is perpendicular to the conveyer belt of paint-spraying production line.
As shown in Figure 2, spray gun fixed bar 11 is connected with slide block assembly 14 by vertical fixed bar 16 and fixed block 15, and fixed block 15 is for by moving up and down at vertical fixed bar 16 vertical range regulated between spray gun and the conveyer belt of paint-spraying production line.
Support 10 comprises rack body 10a, and rack body 10a inside is provided with the elongated slot 8 being parallel to guide rail 9, and vertical fixed bar 16 passes perpendicularly through elongated slot 8.
Rack body 10a is provided with first sensor 4 and the second sensor 4a, for the moving range coordinating PLC to control slide block assembly 14.
Guide rail 9 is provided with limited block 7, for the moving range coordinating first sensor 4 and the second sensor 4a to determine slide block assembly 14.
The present invention is fixed on paint-spraying production line water-screen cabinet place by support 10, and when slide block assembly 14 reciprocatingly moves on the rail 9, spray gun fixed bar 11 is constant to the constant distance on paint-spraying production line upper conveyor belt surface.Upper cover 13 is placed in support 10a main body, can take off when doing maintaining.The bottom of rack body 10a has an elongated slot 8 and reciprocatingly moves for the vertical fixed bar 16 of slide block assembly 14.Spray gun loaded onto by spray gun fixed bar 11, and the distance on spray gun and conveyer belt surface can be moved up and down at the vertical fixed bar 16 of slide block assembly 14 by fixed block 15 and regulate.Slide block assembly 14 upper end is screwed on the slide block of Rodless cylinder 3.Slide block assembly 14 lower end is on the rail 9 bushing by linear bearing, and guide rail 9 is fixed on rack body 10a by fixing fixture block 6, and limited block 7 is equipped with at guide rail 9 two ends, for limiting the spacing that slide block assembly 14 moves reciprocatingly.Air compressing gas is connected with magnetic valve 1 by pneumatics flexible pipe after precise pressure regulating valve 12, then is connected with throw rifle by pneumatics flexible pipe.Air compressing gas is connected with 3 position-5 way magnetic valve 2 by pneumatics flexible pipe after precise pressure regulating valve 12a, then by pneumatics flexible pipe and the external screw thread on Rodless cylinder 3 soon slotting thermoplastic joint 5 be connected with 5a.The circuit of magnetic valve 1 and 3 position-5 way magnetic valve 2 is by PLC programme-control.
The course of work of man made crystal diamond following process spray-painting plant of the present invention is as follows:
When after unlatching swinging button, 3 position-5 way magnetic valve 2 is started working, and the external screw thread to Rodless cylinder 3 inserts thermoplastic joint 5a air feed soon, and the slide block band movable slider assembly 14 of Rodless cylinder 3 inwardly slides, when walk to inner side below sensor 4 time, sensor 4 is to PLC transmission of signal.PLC controls 3 position-5 way magnetic valve 2 to be stopped inserting thermoplastic joint 5a air feed soon to the external screw thread of Rodless cylinder 3, the external screw thread of changed course Rodless cylinder 3 inserts thermoplastic joint 5 air feed soon, the slide block band movable slider assembly 14 of Rodless cylinder 3 outwards slides, when walk to outside below sensor 4a time, sensor 4a is to PLC transmission of signal.PLC controls 3 position-5 way magnetic valve 2 to be stopped inserting thermoplastic joint 5 air feed soon to the external screw thread of Rodless cylinder 3, the external screw thread made into again to Rodless cylinder 3 inserts thermoplastic joint 5a air feed soon, the slide block band movable slider assembly 14 of Rodless cylinder 3 inwardly slides again, does the reciprocating motion gone round and begun again like this.By the reciprocating motion spacing regulating the position of sensor 4 and sensor 4a and limited block 7 can change slide block assembly 14, also just control the stroke of spray gun.The pressure size of air compressing gas can be controlled by adjustment precision pressure regulator valve 12a, also just can the speed of reciprocating motion speed of Rodless cylinder 3 slide block.
When starting spray gun for paint play button, magnetic valve 1 is started working, and to spray gun for paint air feed, spray gun for paint just can spray paint.
The present invention drives spray gun to move reciprocatingly back and forth by cylinder, and spray gun back and forth moves with uniform velocity, and speed can regulate.The fixed bar fixedly sprayed paint is constant with the distance that crystal diamond template is housed, and spray gun is perpendicular to template, the uniformity of crystal diamond paints and lacquers protection film when can ensure spray painting operation like this; The path that spray painting scope of the present invention and streamline direction of advance are passed by overlaps completely, and coating is fully utilized, and avoid waste, and greatly improve the uniformity of spraying, the film thickness formed is constant, appearance looks elegant.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
