Description

TECHNICAL FIELD

[0001] The present application relates to the field of loading and unloading transportation, in particular to a loading and unloading cover machine clamp jaw moving mechanism. BACKGROUND

[0002] The loading and unloading cover machine clamp jaw mainly realizes the gripping and releasing of the claw fingers through motor driving, thereby realizing a series of functions such as grabbing, carrying and positioning of the articles, and is widely used in port yards, logistics centers, warehouses and manufacturing industries, etc. After the loading and unloading cover machine clamp jaw grabs the articles, the articles need to be carried through a moving mechanism. The existing moving mechanism usually adopts synchronous belt and fixed connection with the mounting end of the clamp jaw, and the synchronous belt is driven by a gear to form the moving effect of the clamp jaw. However, with the increase of use time, the synchronous belt is prone to aging and loosening, thereby affecting the moving function of the clamp jaw. CONTENT OF THE UTILITY MODEL

[0003] In order to improve the problem that the synchronous belt of the conventional moving mechanism is prone to aging and loosening, thereby affecting the carrying efficiency of the articles, and to reduce the maintenance cost, the present application provides a loading and unloading cover machine clamp jaw moving mechanism.

[0004] The loading and unloading cover machine clamp jaw moving mechanism provided by the present application adopts the following technical scheme:

[0005] A loading and unloading cover machine clamp jaw moving mechanism, comprising a main frame, a driving shell for linear driving is arranged inside the main frame, a threaded rod is rotationally arranged inside the driving shell, a connecting shell is arranged on one side of the bottom of the driving shell, and the connecting shell is movably penetrated through the driving shell and is threadedly connected with the surface of the threaded rod at the top thereof;

[0006] A lower sealing plate is connected to the bottom of the connecting shell, a power mechanism for providing power is fixedly arranged at the bottom of the lower sealing plate, a supporting plate is fixedly arranged at the bottom of the power mechanism, and a claw hook structure for fixing a cover plate is connected to the output end of the power mechanism and penetrates through the bottom of the supporting plate.

[0007] Through the above technical scheme, the claw hook part of the claw hook structure grabs the cover plate, and then the output end of the power mechanism is stretched to drive the claw hook structure to rise. The connecting shell is driven by the threaded rod, and the connecting shell and the power mechanism are integrally fixed, so that the claw hook structure is horizontally translated, thereby driving the cover plate to displace. The action is simple and the production efficiency is maintained.

[0008] Preferably, an upper sealing plate is movably abutted to the position of the lower sealing plate at the top of the driving shell, a plurality of connecting rods are fixedly arranged on the surface of the upper sealing plate, one end of each connecting rod away from the upper sealing plate penetrates through the bottom of the lower sealing plate, and the penetrating end of each connecting rod is used to fix the upper sealing plate by using a nut.

[0009] By adopting the above technical solution, multiple connecting rods connect the upper sealing plate and the lower sealing plate, so that the upper sealing plate, the lower sealing plate and the drive housing are fixed as a whole, thereby improving the stability of the drive housing when moving.

[0010] Preferably, positioning columns for fixing the cover plate are fixedly provided on both sides of the bottom of the support plate located on the claw hook structure.

[0011] By adopting the above technical solution, the positioning columns are located on both sides of the claw hook structure. When the claw hook structure descends to grab the cover plate, the two positioning columns abut against the surface of the cover plate to form a fixed position, preventing the cover plate from shifting and facilitating the grabbing action of the claw hook structure.

[0012] Preferably, a servo motor is fixedly provided on one side of the drive housing inside the main frame, and an output end of the servo motor is fixedly connected to the threaded rod.

[0013] By adopting the above technical solution, the output shaft of the servo motor rotates, thereby driving the threaded rod to rotate synchronously, providing power for the movement of the connecting shell.

[0014] Preferably, a foldable accordion cover is fixedly provided between the lower sealing plate and the support plate and surrounds the power mechanism.

[0015] By adopting the above technical solution, the accordion cover is telescopic and folded in coordination with the overall movement of the power mechanism, thereby preventing external dust and other debris from contacting the output end of the power mechanism, thereby playing a protective role.

[0016] Preferably, a cover plate positioning and conveying structure is fixedly provided on one side of the main frame at the bottom of the driving housing.

[0017] By adopting the above technical solution, the cover plate positioning and conveying structure moves the cover plate to one side of the bottom of the driving housing, so that the hook structure grabs the cover plate to assemble the box body.

[0018] Preferably, a box body positioning and conveying structure is fixedly provided on one side of the cover plate positioning and conveying structure in the main frame.

[0019] By adopting the above technical solution, the box body positioning and conveying structure transports the box body to one side of the bottom of the drive housing, thereby facilitating the installation of the box body.

[0020] Preferably, a cover plate line blocking structure is fixedly provided at the bottom of the cover plate positioning and conveying structure, and a box body line blocking structure is fixedly provided at the bottom of the box body positioning and conveying structure.

[0021] By adopting the above technical solution, the cover line blocking structure blocks the transported cover and makes the cover stop, thereby facilitating the claw hook structure to grab the cover. At the same time, the box body line blocking structure blocks the box body after the movement is completed to form a stop, thereby facilitating the claw hook structure to place the cover on the top of the box body.

[0022] To sum up, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The threaded rod is rotated to drive the connecting shell to move, which cooperates with the extension end of the power mechanism to operate, so that the claw hook structure has lifting function while grabbing, effectively improving the grabbing flexibility of the claw hook structure and improving production efficiency. At the same time, the linear drive is used to drive the claw hook joint to move, which effectively avoids the problems of easy aging, loosening and falling of conventional synchronous belts, and reduces maintenance cost.

DETAILED DESCRIPTION

[0028] The following will be described in detail in combination with the accompanying Figure 1-Figure 3 The present application will be further described in detail.

[0029] The present application discloses a cover loading and unloading machine clamp jaw moving mechanism.

[0030] The "up, down, left and right" perspective of the device is based on Figure 1 The direction of the drawing is the reference.

[0031] Referring to Figure 1 , Figure 2 A cover loading and unloading machine clamp jaw moving mechanism, comprising a main frame 1, the main frame 1 is assembled by a plurality of transverse and longitudinal arranged connecting columns through screws, forming a structure with hollow inside and communicating with four sides, a drive shell 2 is fixedly arranged at the upper position inside the main frame 1, the outer surface of the drive shell 2 is fixedly connected with the connecting column through screws, a cavity is formed in the drive shell 2, and the cavity is communicated with the outside through the through holes on both sides of the drive shell 2, a threaded rod 17 is rotatably connected to the inner wall of the cavity, a connecting shell 8 is threadedly connected to the surface of the threaded rod 17, the connecting shell 8 extends to the outside through the through holes of the cavity on both sides, and the upper sealing plate 3 is fixedly arranged on the top of the drive shell 2.

[0032] It should be noted that a servo motor 14 is fixedly installed inside the main frame 1 on one side of the outer surface of the drive housing 2. The output shaft of the servo motor 14 is movable and penetrates into the interior of the drive housing 2 and is fixedly connected to the threaded rod 17. A plurality of connecting rods 4 are fixedly provided on the upper end surface of the upper sealing plate 3 around the position of the connecting housing 8. The connecting rods 4 are fixedly connected to the upper sealing plate 3 through nuts. The bottoms of the plurality of connecting rods 4 are fixedly connected to a lower sealing plate 5. The lower sealing plate 5 is located at the bottom of the drive housing 2. The bottoms of the plurality of connecting rods 4 all penetrate the lower end surface of the lower sealing plate 5 and are fixedly connected through nuts.

[0033] The connecting rod 4 connects the upper sealing plate 3 and the lower sealing plate 5, and is fixedly connected with the bottom of the upper sealing plate 3 and the connecting shell 8 to form an integral fixation. At the same time, a fixed fulcrum is reserved for the installation of the subsequent power mechanism 6. The output shaft of the servo motor 14 drives the threaded rod 17 to rotate, thereby driving the connecting shell 8 to translate along the surface of the threaded rod 17. The movement of the connecting shell 8 drives the upper sealing plate 3 to move. The upper sealing plate 3 makes the lower sealing plate 5 move synchronously through the connecting rod 4, thereby driving the subsequent power mechanism 6 to translate, thereby providing moving power for transporting the cover plate, avoiding the problem that the conventional synchronous belt drives the connecting shell 8 to move easily due to aging, loosening, and falling off, has long-term usability, and reduces maintenance costs.

[0034] Reference Figure 1 、 Figure 3 The lower end surface of the lower sealing plate 5 is located between multiple connecting rods 4 and is fixed with a power mechanism 6. The access end of the power mechanism 6 is located at the top, and the circuit is connected by the upper end surface of the lower sealing plate 5 passing through the access end to form a circuit connection. A support plate 9 is fixed at the bottom of the power mechanism 6, and a claw hook structure 11 is fixed on the lower end surface of the support plate 9, and the output end of the power mechanism 6 is movable through the support plate 9 and docked with the claw hook structure 11. At the same time, an accordion cover 7 is fixed around the power mechanism 6 between the lower sealing plate 5 and the support plate 9. The accordion cover 7 can be telescopically folded, and the upper and lower ends of the accordion cover 7 are sealed and fixed with the lower end surface of the lower sealing plate 5 and the upper end surface of the support plate 9 by adhesive. Positioning columns 10 are fixed on both sides of the claw hook of the lower end surface of the support plate 9 at the claw hook structure 11. The two positioning columns 10 are vertically downward, and the bottom ends of the positioning columns 10 are set to rubber material to increase friction.

[0035] It should be noted that a cover plate positioning and conveying structure 12 is screwed to one side of the bottom of the drive shell 2 in the main frame 1, and the conveying platform of the cover plate positioning and conveying structure 12 is aligned with the center of the claw hook structure 11, and a cover plate line blocking structure 16 is fixed to one side of the conveying platform of the cover plate positioning and conveying structure 12. The plate surface of the cover plate line blocking structure 16 can be rotated and the conveying platform of the cover plate positioning and conveying structure 12 is laterally blocked. A box body positioning and conveying structure 13 is fixed to one side of the cover plate positioning and conveying structure 12 in the main frame 1, and the conveying platform of the box body positioning and conveying structure 13 is aligned with the center of the conveying platform of the cover plate positioning and conveying structure 12, and a box body line blocking structure 15 is fixed to one side of the conveying platform of the box body positioning and conveying structure 13. The plate surface of the box body line blocking structure 15 can be rotated and the conveying platform of the box body line blocking structure 15 is laterally blocked.

[0036] The output end of the power mechanism 6 extends, thereby driving the claw hook structure 11 to move downward. When the power mechanism 6 is extended, the accordion cover 7 continues to cover the power mechanism 6, thereby preventing external debris from contacting the power mechanism 6 and causing damage. As the claw hook structure 11 moves downward, it drives the two positioning columns 10 to contact the top of the cover plate, so that the positioning columns 10 apply downward pressure on the cover plate, thereby firmly fixing the cover plate, making it convenient for the two claws of the claw hook structure 11 to clamp, thereby completing the cover plate picking action. At the same time, the cover plate positioning and conveying structure 12 is used to convey the cover plate, and the box body positioning and conveying structure 13 is used to convey the box body installed with the cover plate, and is respectively equipped with a cover plate line blocking structure 16 and a box body line blocking structure 15, thereby limiting the cover plate and the box body, so that the cover plate and the box body stay at a position directly below the claw hook structure 11 for easy grasping, thereby improving production efficiency.

[0037] The device further includes a power mechanism 6, a claw hook structure 11, a cover plate positioning and conveying structure 12, a box body positioning and conveying structure 13 and a servo motor 14, which are all existing technologies and their structural principles are not described in detail.

[0038] The implementation principle of the clamping moving mechanism of a cover loading and unloading machine in an embodiment of the present application is as follows: when using this device, personnel control the operation of the cover plate positioning and conveying structure 12 through a microcomputer, and the conveyor belt of the cover plate positioning and conveying structure 12 transports the cover plate to the conveying platform position. At this time, the plate surface of the cover plate line blocking structure 16 is horizontally blocked to intercept the cover plate, so that the cover plate continues to stay on the surface of the conveying platform, and then the power mechanism 6 is powered on to drive the claw hook structure 11 to descend. As the claw hook structure 11 descends, the bottom of the two positioning columns 10 are driven to abut against the surface of the cover plate, thereby pressing the cover plate to form a fixation, and then the two claw hooks of the claw hook structure 11 move toward each other, thereby hooking up the two sides of the cover plate to form a clamp, thereby completing the grabbing action of the cover plate.

[0039] At the same time, personnel control the operation of the box body positioning and conveying structure 13 through a microcomputer, and transport the box body that needs to be installed with the cover plate to the position of the conveying platform. At this time, the plate surface of the box body line blocking structure 15 blocks the box body laterally, intercepts the box body, and makes the box body continue to stay on the surface of the conveying platform. Then the power mechanism 6 drives the claw hook structure 11 to rise, and at the same time the servo motor 14 runs. The output shaft of the servo motor 14 drives the threaded rod 17 to rotate, thereby moving the connecting shell 8. When the connecting shell 8 drives the claw hook structure 11 to move above the box body, the servo motor 14 stops running, and then the power mechanism 6 drives the claw hook structure 11 to descend, so that the cover plate is pressed downward into the top of the box body, and then the two claws of the claw hook structure 11 move in opposite directions to cancel the clamping of the cover plate, thereby completing the installation of the box body.

[0040] The above are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
