Specifically, sub-material portion 105 is with the state shown in from the state transfer shown in Fig. 9 to Figure 10, and then the mode turning back to the state shown in Fig. 9 moves back and forth.Namely, in fig .9, lower baffle plate 107 closes chute 103, overhead gage 106 opens chute 103, then, sub-material portion 105 is moved along the direction shown in arrow C 1, lower baffle plate 107 is opened chute 103 and a screw 50 is separated and outlet 101 along from the direction shown in arrow B to screw conveyer structure 10 is moved, meanwhile overhead gage 106 is closed chute 103 and screw 50 is below blocked, thus is transformed into the state shown in Figure 10.In Fig. 10, lower baffle plate 107 opens chute 103, and overhead gage 106 closes chute 103, then, sub-material portion 105 is moved along the direction shown in arrow C 2, thus is transformed into the state shown in Fig. 9.
Like this, utilize the slideway being formed with chute, can by spacing for screw in chute, in addition, by being arranged at the sub-material portion on slideway, a screw can be isolated one by one and make this screw slide out to outlet along slideway, thus the discharging of the screw of single can be realized, the accumulation of screw, stuck can be avoided.
(screw maintaining body)
Screw maintaining body 20 possesses screw holding plate 201, support 202 and cylinder 203.
Support 202 possesses top board 204, base plate 205 and links the post 206 of top board 204 and base plate 205.
Cylinder 203 is arranged on base plate 205, and drives screw holding plate 201 that screw holding plate 201 freely can be moved along horizontal direction X.
At this, as the driving mechanism driving screw holding plate, use cylinder, but, be not limited to this, as long as screw holding plate can be driven to make screw holding plate can along the mechanism of horizontal direction freely movement, also can be the arbitrary driving mechanism beyond cylinder, such as, also can be motor etc.
In addition, as shown in figure 11, at the front end 201a of screw holding plate 201, be formed by the U-shaped recess 207 of the head 501 for receiving screw 50 and the maintaining part 209 that forms for the U-shaped hole 208 in the post portion 502 of receiving screw 50.
U-shaped recess 207 caves in from a face S1 the thickness direction of screw holding plate 201 to S2 side, another face and the end face S3 opening of front end 201a at screw holding plate 201.
U-shaped hole 208 is from the end face S3 opening of the through front end 201a to another face S2 and at screw holding plate 201 of the bottom 207a of U-shaped recess 207.
In addition, when screw 50 is held in maintaining part 209, screw 50 is supported and is held in the bottom 207a of U-shaped recess 207.
Like this, utilize U-shaped recess and U-shaped hole, can reliably screw be held in maintaining part to prevent upset, the deflection of screw.
Further, U-shaped recess 207 also can possess the 1st medial surface 207S with the shape of the form fit of the lateral surface of the head 501 of screw 50, U-shaped hole 208 also can possess the 2nd medial surface 208S with the shape of the form fit of the lateral surface in the post portion 502 of screw 50.Like this, can more reliably screw be held in maintaining part to prevent upset, the deflection of screw.
When adopting the screw in head and the columned post portion possessing roughly dome shape, the cross sectional shape of the 1st medial surface 207S is circular arc, the cross sectional shape of the 2nd medial surface 207S is circular arc, but, be not limited to this, when employing socket cap screw, square head screw, hexagonal head screw, countersunk head screw etc., as long as make the form fit of the lateral surface of the shape of the 1st medial surface and the head of screw and the form fit of the lateral surface in the shape of the 2nd medial surface and the post portion of screw.
In addition, in the present embodiment, as shown in figure 11, U-shaped hole 208 is made up of the 2nd hole portion 211 of the 1st square hole portion 210 and circular arc.As the diameter in the 2nd hole portion 211, preferably the diameter in the 2nd hole portion 211 is greater than the outside diameter d in the post portion 502 of screw 50 and is less than the outer diameter D of the head 501 of screw 50.Like this, reliably can guarantee that the post portion of screw is incorporated in the hole portion in U-shaped hole and the head of screw is supported on the bottom of U-shaped recess, thus more reliably can ensure the attitude stabilization of screw.
In addition, screw maintaining body 20 is by elastic mechanism 70 resiliency supported.Elastic mechanism 70 comprises erects the guide pillar 701 be arranged on pedestal 80 and the spring 702 be enclosed within guide pillar 701.Base plate 205 is by spring 702 resiliency supported.
Like this, screw maintaining body 20 freely can move up and down along vertical Y (that is, along guide pillar 701).
(screw is screwed into mechanism)
Screw is screwed into mechanism 40 to be possessed screwdriver and criticizes mouth 401 and extending bracket 402.
Screw is screwed into mechanism 40 and freely can be moved along vertical Y by the driving of electric cylinder (not shown).Owing to driving screwdriver to criticize mouth by electric cylinder, therefore, there is the advantage of the controlled and registration of motion stabilization, speed etc.
At this, as the driving mechanism driving screw to be screwed into mechanism, make electricity consumption cylinder, but, be not limited to this, as long as can drive screw be screwed into mechanism make screw be screwed into mechanism can along the mechanism of vertical freely movement, also can be the arbitrary driving mechanism beyond electric cylinder, such as, also can be cylinder etc.
Further, move along vertical (above-below direction) because screw is screwed into mechanism, therefore, the lower space that screw is screwed into mechanism is comparatively large, thus can corresponding different size or difform various workpiece.
Extending bracket 402 is provided with screw rod 403, and by adjusting screw(rod) 403, thus it is equal with the space D 2 of screw 50 that the space D 1 of extending bracket 402 and top board 204 and screwdriver can be made to criticize mouth 401.Thus, when extending bracket 402 declines (namely moving along vertical Y-direction workpiece 60 side) along vertical Y and is pressed onto on top board 204, screwdriver is criticized mouth 401 and is just abutted with screw 50.
Then, with reference to Fig. 3 ~ Fig. 8, the course of work screw involved by present embodiment being screwed into automatically to device is described.
First, as shown in Figure 3, being arranged in a row screw 50 on slideway 104 by making sub-material portion 105 is the state shown in Figure 10 and be separated a screw 50 and this screw 50 slides to the outlet 101 of screw conveyer structure 10 and is received to by the U-shaped recess 207 that forms maintaining part 209 and being arranged in the opening end face S3 of U-shaped hole 208 maintaining part 209 being positioned at the front end 201a of screw holding plate 201 connected with the outlet 101 of screw conveyer structure 10 from the state transfer shown in Fig. 9.Like this, utilize the maintaining part of screw holding plate, reliably can ensure the attitude stabilization of screw.
At this, so-called " attitude of screw ", refer to and to be supplied in the overall process of tightening of screw 50 screw 50 with the head 501 of screw 50 and post portion (threaded portion) 502 mode down of screw 50 becomes vertically (vertical) state upward from screw 50, in more detail, refer to and be screwed into mechanism 40 and the post portion (threaded portion) 502 of screw 50 towards the mode of workpiece 60 become vertically (vertical) state with the head 501 of screw 50 towards screw at the screw 50 in the overall process of tightening of screw 50 of being supplied to from screw 50, but, under the state of placing screws etc., the attitude of screw also can become head down and post portion (threaded portion) upward (namely, head contact is in placed side) such attitude.
Then, as shown in Figure 4, mouth 401 criticized by screwdriver and (namely extending bracket 402 declines along vertical Y, move to workpiece 60 side), when extending bracket 402 is pressed in the top board 204 of support 202 of screw maintaining body 20, screwdriver is criticized mouth 401 and is abutted with the cross recessed center on the head 501 of screw 50 (that is, the central shaft E2 of the screwdriver central shaft E1 and screw 50 that criticize mouth 401 overlaps), meanwhile, sub-material portion 105 turns back to the state shown in Fig. 9.Like this, the central shaft of the central shaft and screw of criticizing mouth due to screwdriver overlaps, therefore, it is possible to more accurately position screw thus more reliably can keep the attitude of screw.
At this, the central shaft E1 that mouth 401 criticized by screwdriver is parallel to vertical Y, and the central shaft E2 of screw 50 is parallel to vertical Y.
Then, as shown in Figure 5, mouth 401 criticized by the screwdriver that screw is screwed into mechanism 40 and extending bracket 402 continues to decline along vertical Y, screw maintaining body 20 declines under the suppressing action of extending bracket 402, the spring 702 be enclosed within guide pillar 701 is compressed, thus screw maintaining body 20 and screw are screwed into mechanism 40 synchronously declines, screw 50 move to workpiece 60 be screwed into position A after, screw is screwed into mechanism 40 and suspends mobile.
At this, the downforce due to extending bracket 402 acts on top board 204, and therefore, the cylinder 203 be arranged on base plate 205 is directly not stressed, thus structure can be made firmer and extend service life of cylinder.
Then, as shown in Figure 6, screw holding plate 201 detaches screw 50 under the driving of cylinder 203.
Then, as shown in Figure 7, screwdriver is criticized mouth 401 and is declined, and is screwed in workpiece 60 by screw 50.In the process be screwed into, because screw holding plate 201 has detached screw 50 as shown in Figure 6, namely screw holding plate 201 has retreated to the position be separated with screw 50, therefore, screw 50 is screwed into mechanism 40 by screw and is screwed into workpiece 60 under the state do not kept by screw maintaining body 20, therefore, screw be screwed into mechanism can independently and unhinderedly screw is installed on workpiece.
Finally, as shown in Figure 8, mouth 401 criticized by screwdriver and extending bracket 402 rises along vertical Y and resets, spring 702 resilience and being resetted by screw maintaining body 20, cylinder 203 drives screw holding plate 201 to make screw holding plate 201 re-move position to connecting with the outlet 101 of screw conveyer structure 10 simultaneously.
Thus, the working cycles that screw is screwed into device automatically terminates.
According to the present embodiment, screw 50 moves to from the outlet 101 of screw conveyer structure 10 and workpiece 60 is screwed into position A under its attitude to be kept by screw maintaining body 20 and is screwed into the state that mechanism 40 abuts with screw, afterwards, screw 50 is screwed into mechanism 40 by screw and is screwed in workpiece 60 under the state do not kept by screw maintaining body 20, therefore, no matter screw is very short or very long, the upset that screw all can not occur because vibrations wait is being supplied in the overall process of tightening of screw from screw, deflection, the attitude of screw can both be reliably kept and stably automatically screw can be screwed into.
Above, be illustrated embodiments of the present invention, but the present invention is not limited to above-mentioned embodiment, those skilled in the art can be out of shape the present invention when not departing from connotation of the present invention and scope as required and change.These distortion and change all fall within the scope of the present invention.
