Abstract

The utility model discloses a vacuum suction pen used for picking and placing a solar cell slice. The vacuum suction pen includes a penholder possessing a tubular cavity, a sucker, and a control air hole which is arranged on the periphery of the penholder and is used to communicate the tubular cavity with the outside, an elastic push type switch which can seal or reveal the control air hole, and a rubber pad which covers the back of the sucker. The rubber pad is provided with sections of through holes which reveal the back of the sucker to the air. The back of the sucker is provided with material suction air holes which are arranged in the centers of the sections of through holes. The front of the sucker is provided with a star-like air pathway which communicates with the material suction air holes and the tubular cavity of the penholder, so the reject rate in the material suction is reduced, and the vacuum suction pen is easy to use.

Description

A kind of vacuum WAND that is used to pick and place solar battery sheet

Technical field

the utility model relates to a kind of vacuum WAND that is used to pick and place solar battery sheet.

Background technology

are employed vacuum WAND in picking and placeing the field of solar battery sheet at present, and sucker is plate, and the back side of sucker is harder; Groove is offered in center, the back side at sucker, and the suction pore is opened in the bottom of groove, and the suction pore is connected with the vacuum generating device that is arranged at the penholder inner chamber; During work, the battery sheet externally is adsorbed on groove under the effect of powerful air pressure, if the battery sheet is thinner; Then be very easy to take place depression or crackle towards groove, in addition broken, very easily cause failed part; And existing vacuum WAND in use, is to have the finger shutoff of gloves or expose the control pore through operation element, when removing finger; Because external pressure, gloves are held at control pore place easily, have brought inconvenience to use.

Summary of the invention

The purpose of the utility model provides the vacuum WAND that the failed part rate that reduces, easy to use being used to pick and place solar battery sheet.

are for achieving the above object; The technical scheme that the utility model adopts is: a kind of vacuum WAND that is used to pick and place solar battery sheet; Said vacuum WAND comprises penholder with tube chamber, adsorbable or discharge the sucker of said solar battery sheet; On the outer peripheral face of said penholder, offer the control pore, said tube chamber is connected with the outside through said control pore, on the outer peripheral face of said penholder, connects the elasticity push switch that can block or expose said control pore is set; Front at said sucker is provided with the gas passage; Be sticked at the back side of the said sucker rubber blanket of available buffer active force is offered on said rubber blanket and can be made said sucking disc back side be exposed to airborne multistage perforation, at the center of every section said perforation the suction pore that is opened in said sucking disc back side is set; Said gas passage is connected with the outside through said suction pore, and said penholder tube chamber, said gas passage are connected.

preferably, said elasticity push switch comprises that an end is connected the flexible keypad of said penholder outer peripheral face, is connected being used on the said flexible keypad and blocks the contact of said control pore.

preferably, the said perforation of multistage is arranged and is annular.

further, said gas passage comprises the center channel that is communicated with said penholder tube chamber, along the star-like path that said sucker circumferential direction is extended, said center channel, said star-like path are connected.

owing to the utilization of technique scheme, the utility model compared with prior art has advantage: the rubber blanket that covers sucking disc back side is set, because rubber blanket itself can be done certain elastic deformation; According to the I=Ft formula of momentum, bigger even the battery sheet is drawn into the momentum of sucking disc back side, because the cushioning effect of rubber blanket; Also can reduce directed force F, thereby avoid the damage of battery sheet, offer multistage and run through the positive sucking disc back side that makes of rubber blanket and be exposed to airborne perforation with the back side; Center every section perforation is provided with the suction pore that is opened in sucking disc back side, and during work, the suction of drawing the battery sheet produces rather than concentrate on a place by each suction pore; Owing to discontinuity is damaged, further must reduce the failed part rate when having avoided the battery sheet to be drawn, the elasticity push switch has been set at the penholder outer peripheral face; Be connected with and control the contact that the size of pore is complementary on the switch; When pressing switch, contact can be blocked the control pore, during trip switch; Switch drives contact and throws off the control pore under the elastic recovery effect, easy to operate.

Description of drawings

Accompanying drawing 1 is the structural representation in front of a kind of execution mode of the utility model;

accompanying drawing 2 is the structural representation at the back side of a kind of execution mode of the utility model.

Embodiment

The structure of the utility model is further set forth in below in conjunction with accompanying drawing.

Referring to shown in Figure 1, vacuum WAND comprises the penholder 1 with tube chamber, the sucker 7 that is used to draw solar battery sheet, on the outer peripheral face of penholder 1, offers a control pore 4 that is connected with tube chamber ; Elasticity push switch 2 is set, and this switch 2 can adopt the push type spring leaf to make, and has certain angle between switch 2 and the penholder 1; The one of which end is connected on the outer peripheral face of penholder 1, is connected with contact 3 at switch 2 towards a side of penholder 1, and the size of contact 3, control pore 4 is complementary; When pressing switch 2, contact 3 can block control pore 4, during trip switch 2; Under the elastic reaction of spring leaf; Switch 2 drives contact 3 disengaging control pores 4 and realizes automatically reseting, and at the back side of sucker 7 gas passage is set, and the gas passage comprises center channel 6, the triangle type path 5 that is interconnected; Center channel also is connected with the tube chamber of penholder 1, and the gas that flows in three paths of the star-like path 5 of triangle converges at center channel 6 places.

referring to shown in Figure 2, the back side of sucker 7 has covered one deck rubber blanket, and on rubber blanket, offering multistage can be the aerial perforation of the back exposure of sucker 7 as 8; Multistage perforation as 8 head and the tail press close to arrange to be annular each other, be provided with in the center of each perforation as 8 be opened in sucker 7 back sides the suction pore as 9, each suction pore as 9 respectively with the positive star-like path of triangle of sucker 7 in a path be connected; The external vacuum generating device of vacuum WAND, when control pore 4 when being exposed in the air, outside air is taken away by vacuum generating device after like the tube chamber that flows into penholder 1 in 9 by control pore 4, suction pore; Gas flows into from two, tube chamber internal gas pressure balance then, and the suction pore does not produce suction-operated like 9 pairs of battery sheets; Block control during pore 4 when pressing switch 2, gas only is inhaled into as 9 by the suction pore, forms vacuum in the tube chamber; And perforation as 8 and the back side of sucker 7 between also form three place's vacuum chambers, after three place's vacuum chambers were pressed close to the battery sheet, the battery sheet promptly was attracted to the back side of sucker 7 under the effect of ambient pressure; Realized drawing the action of battery sheet; Perforation as 8 syllogic setting have disperseed the stress point of battery sheet, make the battery sheet be not easy to damage; The suction that the setting of rubber blanket also makes the battery sheet receive obtains buffering; Further protected the battery sheet, when discharging the battery sheet, trip switch 2 gets final product.
