[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0027] First, combine Figures 1-3 The vacuum nozzle adapter according to the embodiment of the present invention is described, which is used for the adaptation and installation of an electric screwdriver and has a wide range of application scenarios.

[0028] like Figures 1-3 As shown, the vacuum nozzle adapter of the embodiment of the present invention is used for the adaptation and installation of the electric screwdriver, and includes: an adapter body 1, a nozzle fixing end 2, a negative pressure connector 3 and a nozzle.

[0029] Specifically, if Figures 1-3 As shown, in this embodiment, the top of the adapter body 1 is connected to the electric screwdriver, and a stable connection with the electric screwdriver is achieved through the adapter body 1; the suction nozzle fixed end 2 is installed at the bottom end of the adapter body 1, and the suction nozzle fixed end 2 is used to install and stabilize the suction nozzle; the negative pressure joint 3, the negative pressure joint 3 is arranged on the side wall of the suction nozzle fixed end 2, and the negative pressure joint 3 is connected to the external negative pressure source; the suction nozzle, the suction nozzle is installed at the bottom end of the suction nozzle fixed end 2, the negative pressure joint 3 is connected, and a cavity partition is provided in the suction nozzle, and the cavity partition is a partition plate integrally formed with the suction nozzle, and the cavity partition is arranged at the negative pressure Above the joint 3; when the fixed end 2 of the suction nozzle moves up and down in the adapter body 1, the suction nozzle will move accordingly; the negative pressure joint 3 is changed from the original cylinder position to the lower end of the fixed end 2 of the suction nozzle. Due to the change in the position of the negative pressure joint 3 and the addition of the cavity partition, only a negative pressure cavity will be generated inside the suction nozzle during operation, and it will not spread to other places, ensuring the airtightness of the negative pressure cavity. The negative pressure source is connected through the negative pressure joint 3 to achieve negative pressure absorption of the screws, prevent the screws from falling off, and is economical and reliable; the electric screwdriver passes through the adapter body 1 and the fixed end 2 of the suction nozzle in sequence, and extends into the suction nozzle.

[0030] Further, if Figures 1-3 As shown, in this embodiment, the adapter body 1 includes: a cylinder 11, an adjusting end 12 and a buffer spring 13; the top end of the cylinder 11 is connected to the electric screwdriver, and the bottom end of the cylinder 11 is connected to the adjusting end 12; the inner wall of the cylinder 11 is provided with an internal thread, and the outer wall of the adjusting end 12 is provided with an external thread, and the cylinder 11 and the adjusting end 12 are threadedly connected, and the overall length can be adjusted to adapt to different electric screwdrivers by screwing the cylinder 11 and the adjusting end 12 at different positions; the suction nozzle fixed end 2 is slidably set at the bottom end of the adjusting end 12; the buffer spring 13 is set in the cylinder 11, and the two ends of the buffer spring 13 are respectively abutted against the cylinder 11 and the suction nozzle fixed end 2, and the buffer spring 13 is used to achieve soft contact between the suction nozzle and the screw to reduce product pressure loss.

[0031] Further, if Figures 1-3 As shown, in this embodiment, the adapter body 1 further includes: a stop nut 14, which is screwed onto the adjustment end 12 and screwed into the matching position between the adjustment end 12 and the cylinder 11 to achieve locking and stopping.

[0032] Further, if Figures 1-3As shown, in this embodiment, a bearing 15 is further provided in the adjusting end 12. The bearing 15 is arranged between the adjusting end 12 and the fixed end 2 of the suction nozzle. The bearing 15 is a linear bearing, which can reduce the friction when the fixed end 2 of the suction nozzle slides up and down, thereby achieving smooth sliding.

[0033] Further, if Figures 1-3 As shown, in this embodiment, a first step 111 is provided at the bottom end of the barrel 11, and a second step 121 is provided at the top end of the adjustment tip 12, which cooperates with the first step 111. Since the adjustment tip 12 and the adapter barrel are two separate components, relying solely on threaded tightening will result in coaxial deviation. Once deflected, the suction nozzle at the bottom of the tip will become crooked. For high-precision tightening, the deviation is sufficient to cause tightening failure or even product scrapping. The cooperation of the first step 111 and the second step 121 serves as a reference for installation and application, ensuring that the tip and barrel 11 are coaxial during the adjustment process, minimizing the risk of non-coaxiality.

[0034] Further, if Figures 1-3 As shown, in this embodiment, a sealing ring 112 is provided on the inner wall of the top end of the cylinder 11. The sealing ring 112 seals the electric screwdriver and the cylinder 11 to further ensure air tightness and improve the adsorption effect.

[0035] Further, if Figures 1-3 As shown, in this embodiment, a first nut 61 and a second nut 62 are provided at the top of the adapter body 1. The first nut 61 is screwed onto the top of the outer wall of the adapter body 1, and the second nut 62 is screwed onto the first nut 61. The second nut 62 is used to connect the adapter body 1 to the electric screwdriver. The first nut 61 and the second nut 62 replace the previous welding fixing method with a detachable threaded fixing method, greatly enhancing the convenience of maintenance.

[0036] Further, if Figures 1-3 As shown, in this embodiment, a plurality of top screw holes 63 are opened on the circumferential surface of the second nut 62. The plurality of top screw holes 63 are evenly spaced around the second nut 62, which is beautiful and balanced. When in use, top screws are installed in the top screw holes 63 to strengthen the fixed connection between the electric screwdriver and the adapter.

[0037] Further, if Figures 1-3 As shown, in this embodiment, the nozzle fixing end 2 is in the shape of a stepped cylindrical tube.

[0038] Working principle: The adapter is assembled with the electric screwdriver as a whole, and the negative pressure connector 3 is connected to the external negative pressure generator. The negative pressure generator forms a negative pressure cavity in the inner cavity of the suction nozzle, and the adapter as a whole moves with the electric screwdriver to the designated screw picking position, and performs the picking action vertically downward. When picking up the material, the suction nozzle contacts the screw and is used to avoid hard contact with the help of the buffer spring 13. There is a gap between the suction nozzle and the screw head of the electric screwdriver to ensure air circulation. The negative pressure in the inner cavity of the suction nozzle can be transmitted to the surface of the sucked screw head through the suction nozzle to form suction, thereby achieving the application effect of non-magnetic suction.

[0039] Above, refer to Figures 1-3 The present invention describes a vacuum nozzle adapter according to an embodiment of the present invention, which realizes a stable connection with an electric screwdriver. The change of the position of the negative pressure joint and the addition of a cavity partition ensure the airtightness of the negative pressure cavity, effectively prevent the screws from falling off, and at the same time improve the maintenance convenience and product precision.
