Abstract

The utility model discloses a plastic scraping plate, which is installed on a coating machine. The plastic scraping plate comprises a flat plate which is parallel with a plastic pin plane of the coating machine. One surface of the flat plate, which is opposite to the plastic pin plane, is provided with pin slots, and the number of the pin slots is not less than that of plastic pins. The pin slots can contain the plastic pins. According to the plastic scraping plate adopting the technical scheme, when the plastic pins of the coating machine are automatically cleaned, the plastic pins are in contact into the corresponding pin slots and are in contact with the flat plate, and thus, residual plastic on the plastic pins can be removed; and meanwhile, slot humps among the pin slots are in contact with the residual plastic in gaps between the plastic pins and the plastic pins, and thus, the residual plastic in the gaps between the plastic pins and the plastic pins can be removed.

Description

Glue scraping plate

Technical field

The utility model relates to a kind of annex of coating machine, particularly wherein glue scraping plate.

Background technology

The coating machine of prior art comprises the dispense tip that can move horizontally, and dispense tip is provided with the coplanar plastic pin of a row.When being coated with operation, dispense tip moves along horizontal substrate with certain speed, simultaneously plastic pin gluing on base material.Behind each coating EO, after promptly dispense tip is covered single gluing stroke, all need clean the surplus glue that remains on the plastic pin, be balanced with the glue-spread that guarantees each coating operation, excessive situation influences the gluing quality thereby glue can not occur.

In order to realize the automated cleaning of plastic pin; Common way is the parallel plane glue scraping plate of plastic pin that on coating machine, is provided with dispense tip; Said glue scraping plate comprises flat board; Rise after plastic pin touches glue scraping plate when automated cleaning, residual glue can be trapped on the glue scraping plate and by glue scraping plate and take away on the plastic pin.But such glue scraping plate can't be removed the cull in plastic pin and the plastic pin gap, still can influence the gluing quality.

The utility model content

The technical problem that the utility model will solve is: provide a kind of can clear up on the plastic pin and plastic pin and plastic pin gap in the glue scraping plate of cull.

In order to achieve the above object, the technical scheme of the utility model employing is:

Glue scraping plate is installed on the coating machine, comprises and the parallel plane flat board of the plastic pin of coating machine, it is characterized in that: the dull and stereotyped one side relative with the plastic pin plane is provided with the needle tray of the quantity that is no less than plastic pin, and said needle tray can ccontaining plastic pin.

Adopt technique scheme, the utility model has reached following beneficial effect with respect to prior art:

The vertical needle tray that on flat board, is provided with is then forming convexity between groove between two adjacent needle trays, and needle tray and plastic pin corresponding matching, then the gap corresponding matching between convexity and corresponding two plastic pins of needle tray between groove.When automated cleaning, plastic pin touches in its corresponding needle tray and with flat board and contacts, and can remove the cull on the plastic pin like this; Convexity touches the cull in plastic pin and the plastic pin gap between the groove between the needle tray simultaneously, so just can remove the cull in plastic pin and the plastic pin gap.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further explanation, wherein:

Fig. 1 is the structural representation of dispense tip of the coating machine of prior art;

Fig. 2 is the partial enlarged drawing of Fig. 1 in the A part;

Fig. 3 is the structural representation of preferred implementation of the glue scraping plate of the utility model;

Fig. 4 is the partial enlarged drawing of Fig. 3 in the B part;

Fig. 5 is the cutaway view of Fig. 4 along the C-C line.

The specific embodiment

At first the dispense tip to the coating machine of prior art describes.Like Fig. 1, shown in Figure 2, dispense tip 1 is provided with the coplanar plastic pin 2 of a row, and 2 of two adjacent plastic pins form gap 21.

What Fig. 3-Fig. 5 showed is the preferred implementation of the glue scraping plate of the utility model.As shown in the figure; The glue scraping plate of this embodiment; Be installed on the coating machine; It is parallel plane dull and stereotyped 3 to comprise plastic pin that the coplanar plastic pin of a row 2 with coating machine forms, and dull and stereotyped 3 the one side relative with the plastic pin plane is provided with the needle tray 31 with the plastic pin equal number, and said needle tray 31 is corresponding one by one with plastic pin 2 and can ccontainingly cooperate.Simultaneously, form convexity 32 between groove between the adjacent needle tray 31, gap 21 corresponding matching of

convexity

32 and 2 formation of its needle tray 31 corresponding two plastic pins between said groove.

When automated cleaning was fitted, plastic pin 2 was combined together with needle tray 31, and between groove protruding 32 and plastic pin between gap 21 be combined together.

Like Fig. 3-shown in Figure 5, needle tray 31 is not a groove in the present embodiment, and promptly along dull and stereotyped 3 vertically do not connect up and down, and as a kind of preferred, said needle tray 31 also can be groove.That is to say that needle tray 31 is along vertical up/down perforation of flat board 3, the glue that is trapped in like this on dull and stereotyped 3 can more successfully flow out flat board 3, conveniently to carry out cleaning next time.

In addition, can some optimal ways be proposed to the shape and size of needle tray 31.

Aspect the size of needle tray 31, reasonable example is the diameter of the width of said needle tray 31 more than or equal to plastic pin 2.Certainly; Optimal situation is the diameter that the width of needle tray 31 equals plastic pin 2; Like this needle tray 31 can farthest scrape off attached to plastic pin 2 lip-deep glue, but the width of said needle tray 31 also can reach reasonable frictioning effect than the wide 0.1mm of the diameter of plastic pin with interior words.

Simultaneously, on the improved basis of width more than or equal to the diameter of plastic pin 2 of needle tray 31, the degree of depth of said needle tray 31 is more than or equal to the radius of plastic pin 2.Like this, protruding 32 height can be more than or equal to the radius of plastic pin 2 between groove, and when carrying out the automated cleaning applying, the more effective removal of protruding 32 abilities is attached to the cull in the gap between plastic pin 21 between groove.

At the vpg connection of needle tray 31, reasonable example is that the cross section of said needle tray 31 is semicircle or square.Can reasonable periphery cooperate like this, improve the efficient of frictioning with plastic pin 2.

In addition, can also a kind of improvement be proposed to dull and stereotyped 3 material.For example dull and stereotyped 3 is rubber slabs, and when plastic pin 2 touched rubber slab, rubber slab itself can littlely be out of shape, and helps the glue on the plastic pin 2 to be trapped on dull and stereotyped 3, reaches reasonable frictioning effect; Simultaneously, the rubber material can also prevent that plastic pin 2 from sustaining damage.

Combine the accompanying drawing and the specific embodiment that the utility model has been done detailed explanation above; But the utility model is not limited to this; The technical staff in any present technique field is in the ken that is possessed; Under the prerequisite of the utility model aim, can make various distortion and modification to it.
