Description

Technical Field

[0001] This invention relates to the field of screw picking and placing tools, and in particular to a fully automatic rotary gripping screw picking and placing mechanism. Background Technology

[0002] A mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. A screw is a tool that uses the physical and mathematical principles of the inclined plane, circular rotation, and friction to gradually tighten objects and machine parts. Screw is a general term for fasteners. Screws are indispensable industrial necessities in daily life: such as the tiny screws used in cameras, eyeglasses, clocks, and electronics; the general screws used in televisions, electrical products, musical instruments, and furniture; and the large screws and nuts used in engineering, construction, and bridges. Transportation equipment, airplanes, trams, and automobiles use a combination of screws of different sizes. In the mold processing process, it is necessary to produce matching screws in advance and then pre-place the screws in the mold.

[0003] However, in existing technologies, the robotic arm in automatic screw-feeding equipment for molds does not fix the direction of the screws during the screw-grabbing process, causing the screws to deviate. Furthermore, it is inconvenient to perform rotary feeding operations when picking up and placing screws, and the screws are easily placed crookedly. Additionally, there is no alarm or recognition when the equipment fails to pick up a screw or drops it midway, affecting the efficiency of screw-grabbing operations. Therefore, we propose a fully automatic rotary gripping screw-feeding mechanism to solve the problems existing in the prior art, enabling continuous gripping and feeding of screws of different specifications.

The top end of the lifting screw 23 movably penetrates into the transmission cavity and is fixedly connected to a worm wheel 26 that meshes with the worm gear 25 for transmission. A third motor 20 for driving the worm gear 25 is horizontally provided on the top of the outer end face of the plate 8. A rectangular slot is vertically opened on one side of the inner wall of the lifting cavity. The outer end of the connecting plate extends from the rectangular slot and is fixedly connected to the inner end face of the sliding seat 7. Guide strips are vertically fixed to the front and rear ends of the outer end face of the lifting plate 8. Guide grooves that cooperate with the guide strips are vertically opened on the front and rear ends of the inner side of the sliding seat 7. The vertical plate body of the L-shaped plate 11 slides against the outer wall of the electric push rod 10. The bottom of the telescopic end of the electric push rod 10 is fixedly connected to the L-shaped plate 11. A drive motor is horizontally provided inside the mounting cylinder 14. The drive shaft of the drive motor is coaxially fixedly connected to one end of the mounting shaft 21.

It can effectively improve the screw clamping operation of the clamping component in various positions in the operating space, and effectively improve the convenience and efficiency of the mechanism in use.

[0034] In this invention, the clamping assembly includes a horizontally opened groove in the middle of the bottom surface of the upright plate 15, a movable plate 27 slidably disposed on both sides inside the groove, and a clamping plate 28 installed on the bottom of the outer side of the movable plate 27. The clamping plate 28 is a vertically placed Z-shaped clamping plate structure. A driving cavity is opened in the lower part of the upright plate 15. A camera can also be installed on the outer side of the upright plate 15. By installing the camera, the position of the fallen screw can be identified, which facilitates subsequent clamping operations. A bidirectional lead screw 29 is horizontally rotatable inside the driving cavity, and a driven bevel tooth is fixedly sleeved in the middle of the shaft of the bidirectional lead screw 29. A micro motor 30 is vertically installed in the upper part of the driving cavity, and the micro motor 30 is vertically mounted in the upper part of the driving cavity. The bottom end of the drive shaft of the type motor 30 is fixedly connected to an active bevel gear that meshes with the driven bevel gear; the inner bottom surface of the drive cavity is laterally provided with a strip-shaped opening that communicates with the slide groove; threaded seats are sleeved at both ends of the bidirectional lead screw 29, and the top end of the moving plate 27 extends through the strip-shaped opening into the drive cavity and is fixedly connected to the bottom of the threaded seat; the clamping surfaces of the two clamping plates 28 are vertically provided with strip-shaped clamping grooves, and the cross-section of the clamping grooves is arc-shaped, and multiple rectangular anti-slip protrusions 31 are evenly provided on the inner arc surface of the clamping grooves; at the same time, detection heads electrically connected to the object detection sensor 9 are installed in the anti-slip protrusions 31 at the upper and lower ends of the inner wall of the clamping grooves, and the detection heads are connected to the object detection sensor 9. The cooperation of the detection sensor 9 facilitates the transmission of detected information to the external control device when no material is picked up or when material is dropped midway. The external control device then identifies the data transmitted by the object detection sensor 9, automatically identifies the fault, triggers an alarm, and controls the mechanism to reset, allowing for the resumption of the material picking operation or the re-clamping of dropped screws. A connecting sleeve 22 is laterally provided on the rear end face of the upright plate 15, which is fitted onto the shaft of the mounting shaft 21. The outer end of the connecting sleeve 22 has an anti-detachment plate. The mounting shaft 21 has a rectangular shaft structure. The detection head interacts with the object detection... The combination of sensor 9 and the clamping assembly facilitates automatic fault identification and alarm operation when screws are not picked up or when they fall off during clamping. The structural design of clamping plate 28 significantly improves the anti-loosening effect when clamping screws. At the same time, the clamping assembly can be rotated and adjusted before or after clamping the screw, which effectively improves the convenience and applicability of clamping screws of different sizes and lengths. This enables automatic material handling and operation with minimal manual intervention, greatly improving the efficiency of continuous screw handling. It is also suitable for handling screws of different specifications and sizes.

[0035] Working principle: In this embodiment, the present invention also proposes a method for using a fully automatic rotary gripping screw picking and placing mechanism, including the following steps:

[0036] Step 1: First, connect the electric turntable 2, electric push rod 10, first motor 16, second motor 19, third motor 20, micro motor 30 and drive motor to the external control equipment through wires. Then, install the equipment next to the external feeder for screw conveying. Then, complete the operation and debugging of each component of the equipment. Then, move the vertical plate 15 of the clamping component toward the screw to be clamped.

[0037] Step 2: When the vertical plate 15 is moved, the first motor 16 needs to be started to drive the transverse lead screw 17 to rotate. The transverse lead screw 17 is driven by the first motor 16 to perform forward and reverse rotation, which can move and adjust the moving seat 5 on the crossbeam 4, so that the longitudinal beam 6 follows the moving seat 5 to move. Then, the lifting plate 8 can drive the vertical plate 15 at the outer end of the L-shaped plate 11 to move and adjust laterally.

[0038] Step 3: After the X-axis position of the upright plate 15 is adjusted, the second motor 19 is started to drive the longitudinal lead screw 18 to rotate. The rotation of the longitudinal lead screw 18 can synchronously adjust the sliding seat 7 on the top of the longitudinal beam 6 and the lifting plate 8 on one side of the sliding seat 7, thereby realizing the Y-axis position adjustment of the upright plate 15, which can further improve the position adjustment operation of the upright plate 15 with the clamping assembly in the X and Y axes.

[0039] Step four: After adjusting the X and Y axis positions of the upright plate 15, the third motor 20 is started to drive the worm gear 25 to rotate. Through the cooperation of the worm gear 25 and the worm wheel 26, the lifting screw 23 can be driven to rotate. Since the threaded tube 24 is fixedly connected to the sliding seat 7 through the connecting plate, the rotating lifting screw 23 will rotate and rise within the threaded tube 24. Through the rotation and rise of the lifting screw 23 relative to the threaded tube 24, the height of the lifting plate 8 can be initially adjusted, and then the height of the upright plate 15 can be vertically adjusted in the Z axis direction. Furthermore, through the cooperation of the worm gear 25 and the worm wheel 26, the rotating lifting screw 23 can be automatically locked, and the lifting plate 8 can be automatically locked in the adjusted position.

[0040] Step 5: After adjusting the X, Y, and Z axial positions of the upright plate 15 and the clamping assembly, the upright plate 15 with the clamping assembly moves to above the screw to be clamped. At this time, the clamping plates 28 on both sides of the bottom of the upright plate 15 are in the open claw state. Then, the electric push rod 10 is activated to push the L-shaped plate 11 to perform a small downward operation, thereby causing the clamping plates 28 to be finely adjusted and lowered to both sides of the screw to be clamped. Then, the micro motor 30 is activated to drive the active bevel gear to rotate. Through the meshing of the active bevel gear and the driven bevel gear, the bidirectional lead screw 29 is driven to rotate forward. The bidirectional lead screw 29 rotates forward, which enables the two moving plates 27 to move closer to each other. The movement of the two moving plates 27 makes it easier for the two clamping plates 28 to clamp the screw, and the screw to be transferred can be clamped in the clamping groove between the two clamping plates 28. The anti-slip protrusions 31 improve the anti-loosening effect when clamping the screw.

[0041] Step six: Next, the drive motor is started to rotate the mounting shaft 21. The adjustable rotation of the mounting shaft 21 allows the vertical plate 15 and the screw held by the clamping assembly to rotate 45° before the screw is placed. The clamping assembly can be rotated and adjusted before or after the screw is clamped, and the rotation angle of the clamping assembly can be adjusted from 0° to 90°. After the screw is clamped, the electric turntable 2 is started to rotate the crossbeam 4 and the longitudinal beam 6 horizontally, allowing the clamped screw to be rotated and switched to the mold slot where it is to be placed. This effectively improves the convenience and applicability of clamping screws of different sizes and lengths.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
