[0028] In modern industrial production, the material grabbing and overturning device is widely used in material handling, assembly line operation and automatic production line scenes, and the work burden caused by manual handling can be reduced through the material grabbing and overturning device. The traditional material grabbing and overturning device usually adopts the structure of directly connecting motor with rotary rod, and sets corresponding adsorption positioning structure on the rotary rod, and realizes overturning by directly driving the rotary rod through the motor. The device occupies large space in single dimension, has large application deployment limitation condition, and the internal structure is unevenly stressed, has problems of shaking and noise, and the stability of operation action is insufficient, and the positioning precision is insufficient.

[0029] In order to reduce the space occupied by the grabbing and overturning device, the utility model designs the basic prototype machine to realize the steering of driving force through two bevel gears, so that the motor drives the rotary rod to rotate in another dimension through the two bevel gears, which can improve the space utilization of the device in different dimensions. However, in the process of transmission, the bevel gears for connecting the rotary rod need to bear a large load, and the operation burden is large. In addition, the bevel gears for driving the passive rotation of the active bevel gears have the problem of uneven stress, which is easy to produce eccentric load, induce vibration and noise, affect the running stability, and there is a return error between the only two bevel gears, which is difficult to meet the application demand of high-precision positioning. Moreover, the transmission connection between the only two bevel gears has insufficient bearing capacity, which is difficult to meet the application demand of high load. In order to solve the above problems, the utility model further improves and innovates to design a compact grabbing and overturning device with compact structure, stable operation, high precision and strong bearing capacity.

The lifting piece 130 is connected to the driving end of the lifting driving module 120. The lifting driving module 120 is used for driving the lifting piece 130 to realize lifting relative to the base 110.

[0033] The rotating assembly 200 comprises a rotating drive module 210, a first bevel gear 220, a second bevel gear 230, a third bevel gear 240, a rotating rod 250 and at least one vacuum suction nozzle 260. The rotating drive module 210 is connected to the lifting piece 130, and the rotating center of the rotating drive module 210 is parallel to the lifting driving track of the lifting drive module 120. The first bevel gear 220, the second bevel gear 230, the third bevel gear 240 and the rotating rod 250 are all rotationally connected to the lifting piece 130 through bearings.

The second shaft center of the second bevel gear 230 is collinear with the rod center of the rotating rod 250. The first shaft center of the first bevel gear 220 is collinear with the third shaft center of the third bevel gear 240. Both the first shaft center and the third shaft center are perpendicular to the second shaft center, so that the first bevel gear 220 can drive the rotating rod 250 to rotate by cooperating with the second bevel gear 230. The first bevel gear 220 and the third bevel gear 240 are respectively meshed and connected to opposite sides of the second bevel gear 230. By arranging the third bevel gear 240 and the first bevel gear 220 symmetrically on opposite sides of the second bevel gear 230, the uniformity of the force received by the second bevel gear 230 can be effectively improved, thereby effectively reducing the eccentric load and unbalanced force, reducing the shaking and noise generated during the overturning process, effectively improving the stability of the rotating action, thereby prolonging the service life of the overall structure. Moreover, the third bevel gear 240 is meshed and connected with the second bevel gear 230, which can offset part of the meshing gap between the first bevel gear 220 and the second bevel gear 230, thereby effectively reducing the back stroke error, further effectively improving the precision of the overturning action, and meeting the application requirements of high-precision positioning. In addition, the third bevel gear 240 shares part of the load, which can effectively distribute the load to each area of the device, thereby effectively improving the carrying capacity of the overall structure of the device, and effectively adapting to high-load application scenarios. The rotating rod 250 is provided with a gas guide channel 251. Each vacuum suction nozzle 260 is connected to the rotating rod 250.

The other end of the gas guide channel 251 is used for connecting a vacuum generator. Preferably, the vacuum generator is connected to the other end of the gas guide channel 251 through a hose.

[0034] Preferably, the lifting drive module 120 can be provided as a lifting cylinder, and the rotating drive module 210 can be provided as a rotating cylinder. According to different application requirements, a plurality of vacuum suction nozzles 260 can be provided to meet the corresponding adsorption and grabbing requirements.

[0035] The rotation driving module 210 drives the rotating rod 250 to realize the overturning positioning through the bevel gear set for transmission, can realize multi-dimensional utilization of space, the overall structure is compact, is conducive to deployment in limited space, can realize the carrying function of grabbing, overturning and lifting of materials, the application range is wide, and by integrating the lifting driving module 120 and the rotation driving module 210, the occupied space of multiple independent modules in the traditional device is reduced; the first bevel gear 220 and the third bevel gear 240 are symmetrically arranged on the opposite sides of the second bevel gear 230, which can make the stress of the second bevel gear 230 more uniform, and the steering mode can effectively reduce the torsional load of the rotation driving module 210, which can effectively prolong the service life of the rotation driving module 210, thereby reducing the eccentric load and unbalanced force, which can significantly reduce the shaking and noise generated during the overturning process, and effectively improve the stability of the rotation action, the symmetrical structure and the uniform stress distribution reduce the wear of the device structure, prolong the service life of the device, reduce the maintenance cost, and the third bevel gear 240 is meshed and connected with the second bevel gear 230, which can effectively offset part of the meshing gap between the first bevel gear 220 and the second bevel gear 230, effectively improve the positioning precision of the overturning, and reduce the return error, which can meet the application requirement of high-precision positioning; in addition, the third bevel gear 240 also shares part of the load, which can relatively evenly distribute the load to each area of the device, thereby effectively improving the load capacity of the overall structure, which can meet the application scene of high load, and the air guide channel 251 is arranged in the rotating rod 250 to realize the communication between the vacuum nozzle 260 and the external vacuum generator, which can realize fast grabbing and releasing of materials, and the design integrates the grabbing, overturning and lifting functions, which is suitable for multiple types of material carrying scenes.

[0036] It can be understood that the first tooth number of the first bevel gear 220 is less than the second tooth number of the second bevel gear 230, and the rotation of the first gear driving the second gear can form a transmission effect of speed reduction and torque increase, which can effectively improve the load capacity of the rotating rod 250 connected to the second bevel gear 230, and slow down the rotation speed of the rotating rod 250, thereby effectively improving the stability of the rotating positioning action of the rotating rod 250.

[0037] It can be understood that the third tooth number of the third bevel gear 240 is equal to the second tooth number, and the second bevel gear 230 follows the rotation under the driving of the first bevel gear 220, and the third bevel gear 240 is used to assist the action of the second bevel gear 230.

[0038] By setting the third number of teeth equal to the second number of teeth, the meshing gap between the second bevel gear 230 and the third bevel gear 240 can be reduced, and the rotation accuracy can be effectively improved. In particular, when the first number of teeth is not equal to the second number of teeth, the meshing gap formed between the first bevel gear 220 and the second bevel gear 230 will be relatively large. By setting the third number of teeth equal to the second number of teeth, the back-and-forth error caused by the first bevel gear 220 can be significantly reduced, thereby improving the accuracy of the rotation positioning and reducing the deviation of the back-and-forth rotation action.

[0039] It can be understood that the first bevel gear 220 is a plastic bevel gear, and the second bevel gear 230 is a titanium alloy bevel gear. By setting the first bevel gear 220 for driving as a plastic bevel gear, good vibration and noise reduction performance can be achieved, and the vibration and noise generated during the rotation driving of the rotation driving module 210 can be effectively reduced. By setting the second bevel gear 230 for connecting the load as a titanium alloy bevel gear, it has very high mechanical strength and can withstand a large load. The structure is light, which not only reduces the weight of the device, but also effectively prolongs the service life.

[0040] Preferably, the first bevel gear 220 is an engineering plastic bevel gear, such as a bevel gear structure made of POM plastic. POM plastic, also known as polyoxymethylene resin, has good self-lubricating properties, which can effectively improve the stability of the transmission action and reduce wear caused during transmission operation.

[0041] It should be noted that the third bevel gear 240 used for auxiliary stabilization can be set as an alloy steel gear, which not only has high mechanical strength and wear resistance, but also can provide stable support and stabilization for the second bevel gear 230, and has low cost, which can save device cost.

[0042] It can be understood that the air hole 261 is provided with a dustproof film 262 away from one end of the air guide channel 251. By increasing the dustproof film 262 structure for filtering dust in the vacuum suction nozzle 260, dust or debris can be effectively prevented from blocking the air guide channel 251, and the reliability of the adsorption and positioning action can be effectively improved. After completing the material grabbing action, the dust on the surface of the dustproof film 262 can be cleaned by back blowing or sweeping, which can effectively ensure the reliability of the adsorption and positioning action.

[0043] Specifically, the vacuum suction nozzle 260 is a self-adaptive flexible suction nozzle, which can effectively improve the adsorption and positioning effect of the vacuum suction nozzle 260 on the material.

[0044] It can be understood that the lifting piece 130 is provided with two supporting blocks 140 located at opposite sides of the rotating rod 250, the rotating rod 250 is provided with a positioning plate 252, the two supporting blocks 140 are located at two ends of a movement path of the positioning plate 252, the movement path of the positioning plate 252 is located above the rotating rod 250, so that when reaching the critical position, the corresponding supporting block 140 can be supported at the bottom of the positioning plate 252 to form a supporting effect.

[0045] The position of the positioning plate 252 is limited by the supporting block 140, thereby limiting the critical position of the rotating rod 250, so that the reliability of the overturning positioning action can be effectively improved, when reaching the critical position, the load of the bevel gear set and the rotary drive module 210 can be effectively reduced through the supporting block 140 at the corresponding position and the positioning plate 252, so that the service life of the overall structure can be effectively prolonged, and the stability of the overall structure can be effectively improved. The states of the two critical positions of the present material grabbing and overturning device are shown in Figs. Figure 1 and Figure 3 .

[0046] It can be understood that the upper surface of each supporting block 140 is provided with an elastic buffer layer 141, the collision impact between the positioning plate 252 and the supporting block 140 can be effectively reduced through the elastic buffer layer 141, so that the stability of the overall overturning action can be effectively improved, preferably, the elastic buffer layer 141 is an elastic silica gel layer, a good elastic buffer effect can be formed through the layer structure of the elastic silica gel.

[0047] It can be understood that the surface of the rotating rod 250 is provided with a reinforcing rib 253, the structural strength of the rotating rod 250 can be effectively improved through the reinforcing rib 253, so that the load capacity of the rotating rod 250 can be improved.
