Detailed Implementation
[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0028] As shown in the figure, an automatic screw-locking device suitable for assembling pruning blades includes: a base 1, a moving mechanism 2 disposed on the base 1, and a screw mechanism 3 disposed directly above the moving mechanism 2.
[0029] The base 1 includes: a base 10, and a stacking assembly 11 disposed on the base 10; the stacking assembly 11 is disposed on one side of the base 10, and the stacking assembly 11 is used to stack materials to be assembled.
[0030] In a preferred embodiment of the present invention, the base 10 is configured as a supporting box frame, the inside of which is used to place the materials to be assembled, and the moving mechanism 2 and the screw mechanism 3 are both disposed above the base 10.
[0031] In a preferred embodiment of the present invention, two stacking components 11 are provided, both of which are arranged in the form of a trough. One stacking component 11 is disposed on the side of the base 10, and the other is disposed on the top of the base 10.
[0032] It should be noted that the base 10 is a supporting frame with a platform on top. The moving mechanism 2 and the screw mechanism 3 are both set on the platform for assembling the pruning blades. A box is set on the bottom frame, and the inside of the box is used to place the materials to be assembled and the control devices of the equipment. Two stacking components 11 are fixedly connected to the outside of the base 10. The stacking components 11 are set as troughs, and several grooves are set on the inner side of the troughs. Different grooves are used to place different parts on the pruning blades. During the assembly process, the workers only need to place the corresponding parts in sequence on the placement components 21 and start the equipment to assemble.
[0033] The moving mechanism 2 includes: a moving component 20, and a placement component 21 disposed in the middle of the moving component 20; the placement component 21 is used to place the material to be assembled and to limit the material to be assembled, and there are several placement components 21.
[0034] In a preferred embodiment of the present invention, the moving component 20 includes a slide rail 24, a moving motor fixedly connected to the slide rail 24, and a pulley 25 fixedly connected to the moving motor; the placement component 21 is slidably connected to the slide rail 24.
[0035] In a preferred embodiment of the present invention, the pulley component 25 includes: a timing belt and a timing pulley that meshes with the timing belt.
[0036] In a preferred embodiment of the present invention, the placement component 21 includes a placement groove 22 and a limiting pin 23 fixedly connected to the periphery of the placement groove 22. The limiting pin 23 is used to fix the material to be assembled.
[0037] It should be noted that there are two placement components 21, which are symmetrically arranged at both ends of the moving component 20. This is so that when one is assembled, the other, which has just been assembled, is moved to the front of the worker. The worker then removes the assembled component and re-places the parts in order. After that, the moving component 20 rotates in the opposite direction, causing the assembled component to move to the front of the worker again. The control component 30 is designed to avoid the overlapping position of the two placement components 21.
[0038] Two movable components 20 are symmetrically arranged, one at each end of the placement component 21. The movable components 20 are housed inside the protective shell. Slide rails 24 are fixedly connected to the protective shell. There are two slide rails 24, both on the same vertical plane, but at different horizontal heights. The two slide rails 24 are slidably connected to the two placement components 21 respectively. A synchronous wheel is provided at each end of the slide rail 24. The synchronous wheel is driven by a movable motor and the two synchronous wheels are connected by a synchronous belt. There are two placement slots 22, which are fixedly connected to the upper and lower synchronous belts of the annular synchronous belt respectively. This allows the two placement slots 22 to move back and forth on different horizontal planes during the forward or reverse rotation of the movable motor, assembling the pruning blades. At the same time, the assembled pruning blades are transported back, thereby improving work efficiency.
[0039] The screw mechanism 3 includes: a control component 30, pneumatic grippers or rotary motors respectively disposed on the control component 30, and a pushing component; a plurality of pneumatic grippers 31 are provided, the pneumatic grippers 31 are used to grip and place screws, and the control component is used to fix the screws.
[0040] In a preferred embodiment of the present invention, the control component 30 includes: a horizontal member 32 and a vertical member 33 disposed above the horizontal member 32; the structure of the horizontal member 32 and the vertical member 33 is the same as that of the moving component 20, the horizontal member 32 is used to drive the vertical member 33 to move horizontally, and the vertical member 33 is used to drive the pneumatic gripper 31 or the rotating motor to move vertically.
[0041] In a preferred embodiment of the present invention, the pushing component includes a pushing box 34, which contains a transfer component and a pushing component. A storage slot is provided at the bottom of the pushing box 34 for placing screws.
[0042] In a preferred embodiment of the present invention, the pusher includes a push groove 35 for placing screws. A sliding plate is provided at one end of the push groove 35 located inside the push box 34. A spring is provided between the sliding plate and the push box 34, and the sliding plate is slidably connected to the push groove 35.
[0043] It should be noted that the push box 34 is arranged in a stepped shape, the push slot 35 is fixedly connected to the push box 34, the slide plate is slidably connected on the push slot 35, and the spring is fixedly connected between the slide plate and the push box 34. The spring can push the slide plate to move to the end away from the spring. During assembly, a screw is placed on the push slot 35 and the slide plate is pushed to compress the spring, so that the spring always pushes the slide plate, thereby pushing the screw into the transfer slot.
[0044] In a preferred embodiment of the present invention, a transfer member is disposed at the other end of the push groove 35. The transfer member includes a transfer motor and a transfer plate 36. A plurality of transfer grooves are provided on the transfer plate 36. The transfer grooves and the push groove 35 are located on the same horizontal plane and are tangent to each other.
[0045] It should be noted that the horizontal component 32 and the vertical component 33 have the same structure as the moving component 20. The moving component 20 is used to control the vertical movement of the placement component 21 directly below the control component 30. The horizontal component 32 is located above the moving component 20 and is used to control the horizontal movement of the vertical component 33. The vertical component 33 controls the pneumatic gripper 31 or the rotary motor to rotate.
[0046] The transfer plate 36 is circular and has four transfer slots evenly distributed on it. The bottom of the transfer plate 36 is fixedly connected to the transfer motor. The transfer motor rotates intermittently, rotating 90° each time, so that each time one transfer slot is directly opposite the push slot. The transfer slot is circular and its size allows only one screw to be placed. This ensures that when the spring pushes the screw through the slide, only one screw is pushed into the transfer slot at a time. In a static state, the transfer slot furthest from the push slot is on the same axis as the pneumatic gripper 31.
[0047] During assembly, the moving component 20 is longitudinally positioned on the base 10. Several horizontal components 32 are arranged side-by-side directly above two moving components 20. Each of the front horizontal components 32 has two vertical components 33, with pneumatic grippers 31 at the bottom of each vertical component 33. The last row of horizontal components 32 has only one vertical component 33, equipped with a rotary motor. Each horizontal component 32 in the front row has a pusher at both ends, used to push screws. The pneumatic grippers 31 are used to grip the screws, and the rotary motor is used to tighten them. During assembly, the parts to be assembled are placed sequentially into the placement slot 22. The moving component 20 moves the placement slot 22 and the unassembled parts within it longitudinally below the horizontal components 32. The assembly moves from front to back, passing through each horizontal component 32. At each horizontal component 32, the moving component 20 stops. The horizontal component 32 and vertical component 33 drive the pneumatic gripper 31 to the pushing component, where it grips the screw and moves it directly above the screw holes of the pruning blade. The screw is then placed in the screw holes. Each of the front horizontal components 32 has two vertical components 33, allowing screws to be gripped and placed simultaneously from both sides. This continues until the last row of horizontal components 32 is reached. The last row of horizontal components 32 has only one vertical component 33, connected to a rotating motor to drive it up and down. The rotating motor shaft is vertically downward, and a screwdriver adapted for the screw is fixedly connected to the shaft. As the rotating motor rotates, the screws are tightened sequentially, thus completing the assembly.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
