Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, an embodiment of an automatic picking electric screwdriver of the present invention includes an electric screwdriver body 10 and a vacuum suction nozzle 20, one end of the vacuum suction nozzle 20 is sleeved on the end of the electric screwdriver body 10 and surrounds the screwdriver head 30, and an air suction joint 21 connected to a vacuum generator is disposed at the side of the vacuum suction nozzle 20; after the vacuum nozzle 20 is connected to the screwdriver body 10, an air pressure less than the atmospheric pressure is generated in the space between the vacuum nozzle 20 and the screwdriver body 10 by the vacuum generator, thereby generating an adsorption force to adsorb the screw 50 from the screw 50 transfer device and then lock the screw 50 to the product. If the screw 50 is directly attached to the vacuum suction nozzle 20, the distance between the bit 30 of the screwdriver body 10 and the suction port of the screw 50 is not easy to adjust, if the distance between the bit 30 and the suction port is too close, the screw 50 and the suction port cannot be in complete contact, the suction effect of the screw 50 is reduced, and thus a screw with a large quality cannot be sucked, if the distance between the bit 30 and the suction port is too large, the bit 30 cannot be in close contact with the screw 50, a wire slipping phenomenon is likely to occur during the locking process, on one hand, the screw cannot be locked, on the other hand, the screw 50 is damaged, and the aesthetic degree is affected, therefore, in this embodiment, a floating head 40 is provided, as shown in fig. 2, the floating head 40 is inserted into the vacuum suction nozzle 20, one end of the floating head extends out of the vacuum suction nozzle 20, a through air flow channel 41 is provided in the vacuum suction nozzle 20 and the floating head 40, and the main shaft 11 are connected through an, when the vacuum generator works, the air flow passes through the air flow channel 41 of the floating head 40 and the air flow channel 41 of the vacuum suction nozzle 20 and is separated by the vacuum generator, the screw 50 is adsorbed at one end of the floating head 40 extending out of the vacuum suction nozzle 20, when the screw 50 is locked, the screw 50 is abutted to the locking position of the product, the screwdriver body 10 moves downwards, due to the buffering effect of the elastic piece 42, the floating head 40 is pressed towards the inside of the vacuum suction nozzle 20, the screwdriver head 30 is contacted with the screw 50 in the process that the floating head 40 moves towards the vacuum suction nozzle 20, and the screw 50 is locked on the product, under the condition, the screw 50 is completely contacted with the adsorption port of the floating head 40 before being locked, approximately sealed spaces are formed among the screwdriver body 10, the vacuum suction nozzle 20, the floating head 40 and the screw 50, and the adsorption force on the screw 50 is ensured, so that various screws 50 are suitable for the purpose.

Referring to fig. 2, for the enlarged structure of the vacuum suction nozzle 20 of the present invention, in this embodiment, for further ensuring the sealing effect, the vacuum suction nozzle 20 and the main shaft 11 are further provided with a sealing ring 22, because the screwdriver bit 30 is connected to the main shaft 11 of the screwdriver body 10, thereby the motor-driven main shaft 11 of the screwdriver body 10 drives the screwdriver bit 30 to rotate to complete the loading and unloading of the screw 50, the sealing ring 22 contacts with the main shaft 11, and the friction of the rotation of the main shaft 11 needs to be borne, so that the sealing ring 22 is set as the wear-resistant sealing ring 22. In this embodiment, the screwdriver bits 30 are detachably connected to the main shaft 11, so that when screws 50 of different types are replaced, the screwdriver bits 30 can be replaced correspondingly, and the applicability of the screwdriver body 10 is improved. Furthermore, the elastic member 42 is a compression spring, and the compression spring is sleeved outside the batch head 30, so that the elastic member 42 is prevented from being twisted in the axial direction of the floating head 40, and the buffering effect of the elastic member on the floating head 40 is ensured. Referring to fig. 3, further, since one end of the spring abuts against the main shaft 11, in order to prevent the floating head 40 from being driven to rotate when the main shaft 11 rotates, and the screw 50 at the end of the floating head 40 is in a rotating state, a rotation stop plane 43 is arranged on a side surface of the floating head 40, a rotation stop screw 44 matched with the rotation stop plane 43 is installed on a side surface of the vacuum suction nozzle 20, and the rotation stop screw 44 abuts against the rotation stop plane 43, so that the floating head 40 can move along the axial direction thereof and cannot rotate, and the fitting of the batch head 30 and the screw 50 is facilitated. Meanwhile, in the embodiment, the diameter of the batch head 30 is smaller than the diameter of the air flow channel 41 in the floating head 40, so that even if the batch head 30 is matched with the screw 50 during operation, a gap through which the air flow passes still exists in the floating head 40, and the adsorption of the screw 50 is ensured.

Referring to fig. 4, for the utility model discloses a head 40 cross-sectional view floats, head 40 stretches out the outer one end of vacuum suction nozzle 20 is provided with profile modeling positioning nut 45, and screw 50 cooperates with profile modeling positioning nut 45, and profile modeling positioning nut 45 and screw 50's shape looks adaptation on the one hand guarantee the location to screw 50, and on the other hand, screw 50 laminates with unsteady head 40 more, guarantees the gas tightness for the absorption dynamics to screw 50 is bigger. As preferred, still be provided with a plurality of protruding stupefied 46 along the axial of unsteady head 40 around profile modeling positioning nut 45, protruding stupefied 46 terminal surface be for with 50 top surface complex cambered surfaces of screw, 50 first sides of screw laminate with profile modeling positioning nut, and 50 top surfaces of screw and protruding stupefied 46 cooperate, reduce the contact of 50 top surfaces of screw and unsteady head, under the circumstances that does not influence screw 50 and profile modeling positioning nut 45 complex, increased the adsorption area to screw 50. Because the air suction connector 21 is close to the floating head 40, the air suction connector 21 in this embodiment is an L-shaped connector, and the other end of the air suction connector 21 points to the direction of the electric screwdriver body 10, so as to prevent the connection with the vacuum generator from affecting the adsorption of the floating head 40 to the screw 50.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
