Abstract
The utility model discloses a scraper device capable of resiliently floating upwards and downwards. The scraper device comprises a driving motor disposed on an upper part of a machine frame, and a rotary shaft of the driving motor is connected with a screw rod. A spring base slidably connected with the machine frame is sleeved externally on the screw rod. The upper part and the lower part of the spring base are respectively provided with two springs. A screw nut cooperated with the screw rod is disposed between the two springs in the spring base. A fixing support used for fixing the scraper is disposed on the lower part of the spring base. When the PCB is not flat, the scraper is connected with the spring base to enable the scraper to move upwards and downwards resiliently under the action of the springs in the spring base, thereby the resilient contact between the scraper and the PCB can be realized. The pressure between the scraper and the PCB is the elastic force difference of the two springs, thereby the angle change of the scraper by the rigid contact can be prevented, and the influence on the printing quality can be prevented.
Description
Technical field
The utility model relates to the paste-tin printing apparatus field, particularly a kind of doctor blade device of elastic floating up and down.
Background technology
In paste solder printing technology, the pressure of scraper and angle all have very big influence to printing quality, and present domestic printing machine scraper mechanism all is rigidly connected to each other.When printing,, influence printing quality because the pcb board out-of-flatness can change the deflection of wing, thereby cause scraper angle constantly to change.
The utility model content
The technical problem that the utility model mainly solves provides a kind of doctor blade device of up and down elastic floating, this up and down the doctor blade device of elastic floating can avoid rigidly connected scraper on irregular pcb board, to produce the angle variation, and then influence printing quality.
In order to address the above problem; The utility model provides a kind of doctor blade device of elastic floating up and down, and the doctor blade device of elastic floating comprises the drive motors that is arranged on upper rack up and down, and the rotating shaft of this drive motors is connected with screw mandrel; Said screw mandrel is arranged with the spring base that is slidingly connected with frame outward; The top and the bottom of this spring base are provided with two springs respectively, in this spring base, are provided with between two springs and screw mandrel fit screw rod nut, are provided with the fixed mount of fixed doctor in the spring base bottom.
Preferably, the said spring base outside is provided with gathering sill, and this gathering sill cooperates slip with guide rail on the frame.
Preferably, the rotating shaft of said drive motors is connected with screw mandrel through shaft coupling.
The utility model is the doctor blade device of elastic floating up and down; Comprise the drive motors that is arranged on upper rack; The rotating shaft of this drive motors is connected with screw mandrel, and said screw mandrel is arranged with the spring base that is slidingly connected with frame outward, and the top and the bottom of this spring base are provided with two springs respectively; In this spring base, be provided with between two springs and screw mandrel fit screw rod nut, be provided with the fixed mount of fixed doctor in the spring base bottom.When irregular pcb board out-of-flatness; Scraper is connected with spring base; Make that elasticity moves up and down under the spring action of scraper in spring base, and then realize scraper and pcb board Elastic Contact, the pressure of scraper and pcb board is that the elastic force between two springs is poor; Scraper the male character types in Chinese operas, usu. referring tov the bearded character degree changes when avoiding the rigidity contact, influences printing quality.
Description of drawings
Fig. 1 is the utility model doctor blade device example structure sketch map of elastic floating up and down.
Below in conjunction with embodiment, and with reference to accompanying drawing, realization, functional characteristics and the advantage of the utility model purpose is described further.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of doctor blade device embodiment of elastic floating up and down.
This up and down the doctor blade device of elastic floating comprise the drive motors 1 that is arranged on frame 3 tops; The rotating shaft of this drive motors 1 is connected with screw mandrel 14; The said screw mandrel 14 outer spring bases 4 that are slidingly connected with frame 3 that are arranged with; The top and the bottom of this spring base 4 are provided with two springs 8 respectively, in this spring base 4, are provided with between two springs 8 and screw mandrel 14 fit screw rod nuts 6, are provided with the fixed mount 9 of fixed doctor 11 in spring base 4 bottoms.
Said spring base 4 outsides are provided with gathering sill 7, and this gathering sill 7 cooperates slip with guide rail 5 on the frame 3, can make spring base 4 more steady when sliding up and down.The rotating shaft of said drive motors 1 is connected with screw mandrel 14 through shaft coupling 2.
When irregular pcb board 10 out-of-flatnesses; Scraper 11 is connected with spring base 4; Make spring 8 effect of scraper 11 in spring base 4 down elasticity move up and down, and then realize scraper 11 and pcb board 10 Elastic Contact, the pressure of scraper 11 and pcb board 10 is that the elastic force between two springs 8 is poor; Scraper the male character types in Chinese operas, usu. referring tov the bearded character degree changes when avoiding the rigidity contact, influences printing quality.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
