Detailed description of the invention
For further setting forth the utility model for the technological means reaching predetermined utility model object and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to according to detailed description of the invention, structure, feature and the effect that the utility model proposes, be described in detail as follows.
First embodiment
Fig. 2 is the structural representation that PI coating apparatus that the utility model first embodiment provides assists foreign body eliminating apparatus.Fig. 3 is the perspective view that PI coating apparatus that the utility model embodiment provides assists the dedusting roller of foreign body eliminating apparatus.It should be noted that, the PI coating apparatus that the utility model provides assists foreign body eliminating apparatus to be fixed on the fixed support of PI coating apparatus, in order to succinctly illustrated, only draws the structural representation that this PI coating apparatus assists foreign body eliminating apparatus in Fig. 2.Please refer to Fig. 2 and Fig. 3, described PI coating apparatus is assisted foreign body eliminating apparatus to comprise driving shaft 21, is arranged on the drive rod 22 of driving shaft 21 one end, the first roller bearing 23 (as shown in Figure 3) be fixed on drive rod 22, be set in the dedusting roller 25 of the hollow on the first roller bearing 23.PI coating apparatus assists foreign body eliminating apparatus to be used for carrying out foreign bodies removal to the loading plate 27 be placed on workbench 28.Workbench 28 can drive loading plate 27 to move back and forth between substrate 20 feeding end and PI coating roller along conveying track 26.
As shown in Figure 3, the cylindrical shape of dedusting roller 25 roughly in hollow, be set on the first roller bearing 23, dedusting roller 25 outer surface is provided with adhesion layer 201.Motor (not shown) is arranged on the side of workbench 28, and motor drives driving shaft 21 to drive drive rod 22 to be elevated by reducing gear.Specifically, after a upper substrate P I coating terminates, workbench 28 moves to upstream side substrate 20 feeding end (not shown), in the process of workbench 28 movement, motor control driving shaft 21 drives drive rod 22 to decline, thus drive dedusting roller 25 to drop to the surface of the loading plate 27 be positioned at above workbench 28, dedusting roller 25 at the surface scrolls of loading plate 27 with by adhesion layer 201 adsorption of foreign matter on dedusting roller 25.Preferably, adhesion layer 201 can be the adhesions such as adhesive tape, can stick the foreign matters such as dirt bits by stickiness, but in other embodiments, adhesion layer 201 with electrostatic, and can pass through Electrostatic Absorption foreign matter.
When PI coating apparatus assists foreign body eliminating apparatus to work, loading plate 27 moves along conveying track 26 toward substrate 20 feeding end under the transmission of workbench 28, in this moving process, motor drives driving shaft 21 to drive drive rod 22 that dedusting roller 25 is dropped to the surface of loading plate 27 by reducing gear, and the surface scrolls of loading plate 27 in movement, when adhesion layer 201 touches the dirt bits on loading plate 27, dirt bits can be subject to the effect of viscous force or electrostatic force etc. and be attached on adhesion layer 201.The dirt bits being attached to loading plate 27 surface can be reduced thus, effectively remove foreign matter.Both saved a large amount of time and manpower, guaranteed again the clean of loading plate, and avoided substrate formed protruding under foreign matter supporting role and then occur substrate crackle due to the extruding of P wheel, thus add product percent of pass, improve overall production efficiency.Wherein, in foreign bodies removal process, also can set the number of times of foreign bodies removal or the time of foreign bodies removal.After foreign bodies removal, motor drives driving shaft 21 to drive drive rod 22 to rise by reducing gear, and dedusting roller 25 also rises to certain altitude thereupon, and leaves the surface of loading plate 27, so can not interfere the transport of next substrate and the coating process of PI.
In sum, the PI coating apparatus that the present embodiment provides assists foreign body eliminating apparatus, is sticked the dirt bits on loading plate 27 by adhesion layer 201.Effectively can remove the dirt bits being attached to loading plate 27 surface thus, save a large amount of time and manpower, and guarantee the clean of loading plate, substrate is avoided to be formed protruding under foreign matter supporting role and then occur substrate crackle due to the extruding of P wheel, thus add product percent of pass, improve overall production efficiency.
Second embodiment
Please refer to Fig. 4 and Fig. 5, Fig. 4 is the structural representation that PI coating apparatus that the utility model second embodiment provides assists foreign body eliminating apparatus.Fig. 5 is that the PI coating apparatus shown in Fig. 4 is assisted the dedusting roller in foreign body eliminating apparatus and peels off roller structure schematic diagram.Structure shown in the present embodiment shown in structure to Fig. 2 and Fig. 3 is similar, its difference is, the PI coating apparatus of the present embodiment is assisted foreign body eliminating apparatus also to comprise to be fixed on the second roller bearing 205 on drive rod 22, is set in the stripping roller 202 of hollow on the second roller bearing 205.
Wherein, peeling off the tubular of roller 202 also roughly in hollow, be set on the second roller bearing 205, peeling off roller 202 for removing the adhesion layer 201 on dedusting roller 25.
Preferably, the PI coating apparatus of the present embodiment assists foreign body eliminating apparatus to comprise to be fixed on the collection roller 206 on drive rod 22, for collecting the adhesion layer 201 removed from dedusting roller 25.
When the adhesion layer 201 dedusting roller 25 sticking together foreign matter is peeled off by peeling off roller 202, and when being collected by collection roller 206, first one end of adhesion layer 201 (such as adhesive tape etc.) can be fixed on and peel off on roller 202, stripping roller 202 is driven to drive adhesion layer 201 to the end motion away from dedusting roller 25 by the motor be arranged on workbench 28, remove from dedusting roller 25 to make adhesion layer 201, then, peeling off roller 202 pulls adhesion layer 201 adhesion layer 201 to be pulled to the position of collecting roller 206 further, motor drives collection roller 206 to rotate, being wrapped in make adhesion layer 201 collects on roller 206, thus reach the object being collected in by adhesion layer 201 and collecting on roller 206.
The PI coating apparatus that the present embodiment provides assists foreign body eliminating apparatus, the adhesion layer 201 dedusting roller 202 sticking together foreign matter is removed by peeling off roller 202, and by collecting roller 206, the adhesion layer 201 removed from dedusting roller 202 is collected, so that the replacing of adhesion layer 201 after being stained with foreign matter on dedusting roller 202, thus ensure thoroughly to remove foreign matter, further ensure that the clean of product. at every turn
