In the following, specific embodiments of the invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the invention and do not limit the invention.
As shown in fig. 1, the automatic screw locking machine of the present invention includes a frame 10, a three-axis moving system, a screw locking mechanism 20, a screw feeder 30, and a control system. The three-axis moving system is arranged on the machine frame 10, the screw locking mechanism 20 is arranged on the three-axis moving system, and the control system is connected with the three-axis moving system, the screw locking mechanism 20 and the screw feeder 30. The screw locking mechanism 20 is driven to move freely in the space by controlling the three-axis moving system, the screw automatic feeding process is completed through the screw feeder 30, and the screw locking process is completed through the screw locking mechanism 20.
As shown in fig. 2, the screw locking mechanism 20 includes a movable mounting bracket 21, a powered screwdriver 22, a first pneumatic element 23, a blow-type screw chuck 24, and a second pneumatic element (not shown). The electric screw 22 is disposed on the movable mounting frame 21, and the first pneumatic member 23 drives the electric screw 22 to move up and down by driving the movable mounting frame 21. The blow-on screw cartridge 24 is connected to a screw feeder 30. Preferably, the screw feeder 30 is connected to the air-blown screw cartridge 24 through an air tube 31. A second pneumatic element is connected to the blow-type screw chuck 24 for sucking the screw to the blow-type screw chuck 24 through the air tube 31. The second pneumatic element may be a vacuum pump. The blow screwdriver bit 24 is typically located directly below the powered screwdriver 22, i.e., the powered screwdriver 22 may pass through the blow screwdriver bit 24 to mount the screw to the screw hole of the product to be mounted.
The screw locking mechanism 20 further comprises an auxiliary pneumatic element 25, the auxiliary pneumatic element 25 being connected to the control system. During the up and down movement of the motorized screwdriver 22, the auxiliary pneumatic element 25 in the operating position abuts against the mobile mounting 21, the motorized screwdriver 22 being in the first working position; the auxiliary pneumatic element 25 in the initial position is in abutment with the mobile mounting 21 and the motorized screwdriver 22 is in the second working position. That is, the position of the electric screwdriver 22 is limited by the auxiliary pneumatic element 25 in the initial or operating position, thus adjusting the different working positions of the screw lock. Therefore, the automatic screw locking machine can lock screws at different working positions according to different positions and/or depths of screw holes of products to be loaded, and has high automation degree and operation flexibility.
The first pneumatic element 23 may be a first cylinder. The output shaft of the first cylinder is connected to the movable mounting frame 21, whereby the movable mounting frame 21 and thus the electric screw 22 are driven to move up and down by the extension and contraction of the first cylinder.
The auxiliary pneumatic element 25 may be a second cylinder. In the present embodiment, the second cylinder is located below the first cylinder. The operating position of the auxiliary pneumatic element 25 may be a position in which the second cylinder is extended (not shown in the drawings), and the initial position of the auxiliary pneumatic element 25 may be a position in which the second cylinder is retracted (shown in fig. 2). That is, in the present embodiment, when the second cylinder is in the operating position, that is, the second cylinder is extended, the output shaft of the first cylinder is extended downward until the movable mounting bracket 21 abuts against the second cylinder, the electric screw driver 22 is in the first operating position, and then the electric screw driver 22 performs screw locking at that position; when the second cylinder is in the initial position, that is, when the second cylinder retracts, the output shaft of the first cylinder moves downwards until the movable mounting frame 21 abuts against the second cylinder, the electric screwdriver 22 is in the second working position, and then the electric screwdriver 22 performs screw locking at the position. Obviously, the second operating position is lower than the first operating position. Therefore, the screw locking can be completed at two different working positions at least corresponding to the screw holes at two different heights of the product to be installed.
Because the product to be installed may have more than two screw holes with different heights, or the screw holes are screw holes with different depths embedded into the product to be installed, further, the strokes of the first cylinder and the second cylinder can be preset according to actual requirements, and the specific telescopic lengths of the first cylinder and the second cylinder in the telescopic process can be adjusted through the limiting piece. That is to say the auxiliary pneumatic element 25 can have a plurality of different operating positions. Therefore, the automatic screwing machine is higher in flexibility.
Further, the output shaft of the first cylinder is arranged coaxially with the output shaft of the second cylinder, thereby enabling the movable mounting frame 21 and the second cylinder to abut better.
As shown in fig. 1, a gantry 11 may be disposed on the frame 10, and the three-axis moving system includes an X-axis moving mechanism 41, a Y-axis moving mechanism 42, and a Z-axis moving mechanism 43.

The X-axis moving mechanism 41 drives the product to be loaded to move back and forth, the Y-axis moving mechanism 42 drives the Z-axis moving mechanism 43 and the screw locking mechanism 20 to move left and right, and the Z-axis moving mechanism 43 drives the screw locking mechanism 20 to move up and down, so that three-axis linkage is realized.
In the present embodiment, the screw locking mechanism 20 may include a mounting plate 201 movably mounted on the Y-axis moving mechanism 42. The first and second cylinders may be detachably mounted on the mounting plate 201. The mounting plate 201 may be provided with a guide rail 27, and the movable mounting frame 21 may be moved up and down along the guide rail 27 by the first cylinder. Mounting plate 201 may also be provided with a screw-clip mounting bracket 26, such that air-blown screw clip 24 is mounted on screw-clip mounting bracket 26.
The control system may be disposed in the housing 10, and a plurality of operation buttons 50 electrically connected to the control system are disposed on the housing 10, and the plurality of operation buttons 50 may be used to control the movement of the three-axis moving system, the automatic feeding of the screw feeder 30, and the locking of the screw locking mechanism 20.
As shown in fig. 1, a code scanning gun 60 may be provided on the rack 10 for inspecting the product to be loaded.
According to the automatic screw locking machine, during the up-and-down movement of the electric screwdriver, the auxiliary pneumatic element in the operating position is abutted with the movable mounting frame, the electric screwdriver is in the first working position, the auxiliary pneumatic element in the initial position is abutted with the movable mounting frame, and the electric screwdriver is in the second working position.
