Abstract
Description
Technical Field
[0001] The utility model relates to the field of screw driving equipment, in particular to automatic screw driving equipment. Background Art
[0002] Screws are one of the most commonly used fasteners. A product usually contains dozens or even hundreds of screws. If these screws need to be removed manually, it will take a lot of manpower and time. In recent years, with the development of technology, automatic machines for automatic screw removal have gradually come out. However, these machines can only loosen the screws, and manual collection is required later, so the degree of automation is not high.
[0003] In order to solve the above problems, a Chinese patent with authorization announcement number CN219358623U discloses an automatic screw driving device; the device comprises a first transmission line (1), an automatic drill bit (2) with a screwdriver, a swing arm mechanism (3), an attraction magnet (4), a fixed plate (5) and a scraper (6); the automatic drill bit (2) and the swing arm mechanism (3) are both connected to the first transmission line (1) in an upward and downward sliding manner, and are both arranged above the fixed plate (5); the attraction magnet (4) is connected to the end of the swing arm mechanism (3); the scraper (6) is provided with an inlet (A) and an outlet (B) having the same shape as the attraction magnet (4); the attraction magnet (4) can slide in through the inlet (A) and slide out through the outlet (B);

DETAILED DESCRIPTION
[0019] See also Figure 1-4 The utility model provides an automatic screw driving device, including a working cylinder 1, a channel 2 is provided inside the working cylinder 1, and an electric screwdriver assembly 3 is installed on the working cylinder 1, and a screwdriver at the bottom of the electric screwdriver assembly 3 is inserted into the inside of the channel 2, and a first limiting seat 6 and a second limiting seat 61 are respectively installed at the bottom of the working cylinder 1, and the tops of the first limiting seat 6 and the second limiting seat 61 are movably connected to an articulated seat 5 through a connecting shaft, and a torsion spring is installed outside the connecting shaft of the tops of the first limiting seat 6 and the second limiting seat 61, and the articulated seat 5 is fixedly arranged at the bottom of the working cylinder 1;
[0020] An automatic screw adding assembly 7 is installed on the left side of the working cylinder 1. The automatic screw adding assembly 7 includes a docking cylinder 71. At the same time, the bottom of the docking cylinder 71 is movably connected to the top of the fixing seat 77 through a pin shaft 76, and the bottom of the fixing seat 77 is fixedly connected to the mounting frame 78. The bottom of the docking cylinder 71 is arranged inside the docking port 4, and the docking port 4 is opened inside the working cylinder 1. A conveying platform 9 is arranged at the bottom of the working cylinder 1, and a workpiece 8 is placed on the surface of the conveying platform 9.
[0021] Working principle: When in use, the screw can be put into the interior of the docking tube 71. Under the condition of gravity, the screw enters the interior of the channel 2 and finally falls into the interior of the first limit seat 6 and the second limit seat 61. At this time, the electric screwdriver assembly 3 is under the action of the lifting cylinder (the cylinder is not shown in the figure). The screwdriver on the electric screwdriver assembly 3 moves downward and contacts the screw. The bottom of the screwdriver magnetically absorbs the screw and drives the screw into the interior of the workpiece 8 on the conveying table 9.
[0022] When installing additional screws, it is only necessary to insert the screws into the interior of the docking tube 71, which can greatly increase the working efficiency of the screw driving device.
[0023] As a preferred embodiment, the first limiting seat 6 and the second limiting seat 61 are combined together into a conical configuration, and the cross-sections of the first limiting seat 6 and the second limiting seat 61 are both “C”-shaped.
[0024] like Figure 1-4As shown: the first limit seat 6 and the second limit seat 61 are combined together in a conical setting, and the screw falls into the inside of the first limit seat 6 and the second limit seat 61 and will not fall out. When the screwdriver at the bottom of the electric screwdriver assembly 3 punches the screw, the screw moves downward and overcomes the elastic force of the torsion spring on the connecting shaft of the first limit seat 6 and the second limit seat 61, so that the screwdriver drives the screw to drive the screw into the workpiece 8.
[0025] As a preferred embodiment, the cross-section of the docking port 4 is set to be "L" shaped, and the bottom of the docking tube 71 is inserted into the interior of the docking port 4. At the same time, the bottom outlet of the docking tube 71 is connected to the channel 2, and the screws inside the docking tube 71 enter the first limit seat 6 and the second limit seat 61 from the channel 2.
[0026] The cross section of the docking port 4 is set in an "L" shape; the bottom of the docking tube 71 is a swing structure with the pin shaft 76 as the center of the circle inside the docking port 4;
[0027] When the docking sleeve 71 is in the initial position, the spring 74 is in a normal state;
[0028] When the screwdriver at the bottom of the electric screwdriver assembly 3 moves downward, pressure is applied to the inclined surface of the docking sleeve 71, so that the docking sleeve 71 applies pressure to the spring 74 through the guide seat 72 thereon;
[0029] When the force acting on the docking sleeve 71 disappears, the docking sleeve 71 returns to its initial state under the reset operation of the spring 74.
[0030] The two sides of the docking tube 71 are both welded with fixed guide seats 72 , and the guide seats 72 are provided with guide holes matching the size of the guide posts 73 , while the guide posts 73 are plugged into the guide seats 72 .
[0031] As a preferred embodiment, the guide seat 72 and the guide column 73 are both arc-shaped, and a spring 74 is installed on the outside of the guide column 73. At the same time, one end of the guide column 73 is fixed to the limit frame 75, and the other end of the guide column 73 is screwed and fixed to the fixing seat 77.
[0032] The bottom of the docking tube 71 is a swinging structure with the pin shaft 76 as the center inside the docking port 4. When the docking tube 71 is swinging, the two sets of guide seats 72 on both sides thereof are plugged with guide columns 73, which can limit and guide the docking tube 71 during movement, thereby ensuring the stability of the docking tube 71 during movement.
[0033] The limiting frame 75 is an “L”-shaped structure made of metal material, and one end of the limiting frame 75 away from the guide column 73 is fixedly connected to the fixing seat 77 .
