A gripping mechanism for a box-packing machine

Abstract

This utility model discloses a gripping mechanism for a box-packing machine, including a base and a robotic arm mounted on the base. A stripping rod is located in the middle of the fixed plate, and a stripping plate is located at one end of the stripping rod. A rack is located on one side of the baffle, and a slider is located on the back of the rack. A slide rail is located on the welding plate, and a half-tooth gear is located below the rack. A connecting rod is located between the half-tooth gears. A motor is located on the outer side of one side of the welding plate and is powered by an external power source. This gripping mechanism for the box-packing machine achieves a highly efficient and reliable automatic stripping function. After the box gripping and packing operation is completed, the motor drives the connecting rod to rotate the half-tooth gear. Through meshing with the rack, the half-tooth gear pushes the baffle and the stripping rod, causing the stripping plate to completely separate the box from the gripping suction cup. This effectively solves the problem of incomplete unloading caused by excessive suction and significantly improves the working efficiency and operational stability of the equipment.

It is widely used in automated production lines in industries such as warehousing, food, and pharmaceuticals.

[0003] However, in actual use, the existing box-holding machine's gripping mechanism may not completely separate the box from the suction cup after gripping it, resulting in incomplete unloading and affecting subsequent continuous operation. Utility Model Content

[0004] The purpose of this utility model is to provide a gripping mechanism for a box-making machine, so as to solve the problem mentioned in the background art that, in actual use, the existing box-making machine gripping mechanism may not completely separate the box from the suction cup due to the lack of a material release device, resulting in incomplete unloading and affecting subsequent continuous operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gripping mechanism for a box-making machine, comprising a base and a robotic arm mounted on the base;

[0014] Compared with the prior art, this utility model provides a gripping mechanism for a box-making machine, which has the following characteristics:

[0015] Beneficial effects:

[0016] 1. By configuring the stripping rod, stripping plate, shims, rack, half-gear, connecting rod, slider, slide rail, and motor, the box-packing machine's gripping mechanism achieves efficient and reliable automatic stripping. After completing the box gripping and packing operation, the motor drives the connecting rod to rotate the half-gear. Through meshing with the rack, the rack moves linearly, which in turn pushes the baffle and the stripping rod. Then, the stripping rod precisely pushes out the fixed plate, allowing the stripping plate to completely separate the box from the gripping suction cup. This effectively solves the problem of incomplete unloading caused by excessive suction, significantly improving the equipment's working efficiency and operational stability.

[0017] 2. Through the setting of baffle, spring and shim, when the half gear disengages, the compressed spring immediately releases its elastic force, pushes the baffle to quickly reset, and makes the stripper plate return to the initial position in time, so as to prepare for the next gripping action. The shim plays an important protective role in the stripping process, avoiding surface scratches that may be caused by direct contact between the stripper plate and the box.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The shown is a gripping mechanism for a box-making machine, including a base 1 and a robotic arm 2 mounted on the base 1;

[0025] The robotic arm 2 is equipped with a mounting plate 3, which has two cylinders 4. The mounting plate 3 is equipped with a mounting frame 24, which has outer plates 7 on both sides. The outer plates 7 are equipped with gripping frames 8, which have multiple pairs of gripping suction cups 11 on their inner sides. The outer plates 7 have an inner plate 5 on one side, which has multiple vacuum suction cups 6.

[0026] A stripping frame 9 is provided on the outer side of the gripping frame 8. Two fixing plates 14 are provided on the stripping frame 9. A welding plate 15 is provided on one side of the fixing plate 14. A stripping rod 13 is provided in the middle of the fixing plate 14. A stripping plate 10 is provided at one end of the stripping rod 13. A baffle 19 is provided at the other end of the stripping rod 13. A spring 18 is provided on the outer side of the stripping rod 13. A rack 21 is provided on one side of the baffle 19. A slider 20 is provided on the back of the rack 21. A slide rail 22 is provided on the welding plate 15. A half-tooth gear 23 is provided below the rack 21. A connecting rod 17 is provided between the half-tooth gears 23. A motor 16 is provided on the outer side of one side of the welding plate 15. The motor 16 is powered by an external power supply.

[0027] In this embodiment, the gripping mechanism of the box-making machine mainly relies on the coordinated action of cylinder 4, vacuum suction cup 6, and gripping suction cup 11. The base 1 serves as the supporting foundation for the entire mechanism. The robotic arm 2 is mounted on the base 1 and can move flexibly to adjust its position. The mounting plate 3 is fixed to the end of the robotic arm 2, and two cylinders 4 are mounted on it to drive the gripping action. The mounting frame 24 is set on the mounting plate 3, with outer plates 7 fixed to both sides. A gripping frame 8 is mounted on the outer plate 7, and multiple pairs of gripping suction cups 11 are provided inside the gripping frame 8 for adsorbing the sides of the box. An inner plate 5 is also provided on one side of the outer plate 7, and multiple vacuum suction cups are arranged on the inner plate 5. The tray 6 is used to adsorb the back of the box. The operation method of the box-making machine gripping mechanism is as follows: The robotic arm 2 first moves to the top or side of the box to be gripped. The outer plate 7 and inner plate 5 are adjusted by the extension and retraction of the cylinder 4, so that the gripping suction cup 11 and vacuum suction cup 6 come into contact with the surface of the box. After the vacuum suction cup 6 contacts the box, it starts the vacuum adsorption function. The gripping suction cup 11 adsorbs the carton by pressing, firmly gripping the box. Then the robotic arm 2 lifts the box and moves it to the target position to complete the box-making or handling operation.

[0028] like Figure 2 , Figure 3 and Figure 4As shown, the stripping frame 9 and the gripping frame 8 are fixedly installed by screws. The fixing plate 14 is welded to the stripping frame 9, the welding plate 15 is welded to the fixing plate 14, the stripping rod 13 is inserted into the fixing plate 14, and the stripping rod 13 is welded to the stripping plate 10. A gasket 12 is provided on the front of the stripping plate 10, and the gasket 12 is adhered and fixed to the stripping plate 10. The gasket 12 allows the stripping plate 10 to flexibly contact the carton. The baffle 19 is welded to the stripping rod 13, and the spring 18 is sleeved with the stripping rod 13. The spring 18 is placed between the baffle 19 and the fixing plate 14. The rack 21 is welded to the baffle 19, and the half-tooth... Gear 23 can mesh with rack 21. Slider 20 is fixedly installed with rack 21 by screws. Slide rail 22 is fixedly installed with welding plate 15 by screws. Rack 21 can slide on slide rail 22 through slider 20. Connecting rod 17 is welded to half gear 23. Half gear 23 can mesh with rack 21. Connecting rod 17 is rotatably connected to welding plate 15. Connecting rod 17 is fixedly connected to output shaft of motor 16. Motor 16 is fixedly installed with welding plate 15 by screws. Motor 16 can drive connecting rod 17 to rotate. Connecting rod 17 can drive half gear 23 to rotate.

[0029] Preferably, with the arrangement of the stripping rod 13, stripping plate 10, pad 12, rack 21, half-gear 23, connecting rod 17, slider 20, slide rail 22 and motor 16, after the carton packing machine's gripping mechanism grips the carton and completes the packing, the motor 16 can be started to drive the connecting rod 17 to rotate the half-gear 23. When the teeth of the half-gear 23 mesh with the rack 21, the counterclockwise rotation of the half-gear 23 can drive the rack 21 to move linearly along the slide rail 22, thereby pushing the baffle 19 to compress the spring 18. After the stripping rod 13 pushes out of the fixing plate 14, it can push the stripping plate 10 to completely separate the two sides of the carton from the gripping suction cup 11, avoiding the gripping suction cup 11 from adhering too tightly to the carton, resulting in incomplete unloading. This structure realizes the automatic unloading function after the carton is gripped, improving the overall working efficiency and reliability of the carton packing machine.

[0030] Preferably, the baffle 19, spring 18, and shim 12 are configured such that when the locking teeth of the half-tooth gear 23 rotate to a position where they do not mesh with the rack 21, the compressed spring 18 is elastically reset, thereby pushing the baffle 19 to reset, so that the stripper plate 10 is quickly reset. This avoids the stripper plate 10 resetting too slowly, which would affect the subsequent gripping action of the box-making machine's gripping mechanism, and realizes the reciprocating motion of the stripper plate 10. The shim 12 can effectively protect the surface of the carton and prevent the stripper plate 10 from directly contacting the carton body and scratching the surface of the carton body.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
