[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the rotating bearing device provided by the present invention is described in detail below with reference to the accompanying drawings.

[0044] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a rotating carrying device, including a rotating table 11, a base frame 12, a rotating support structure 2 and a rotating drive mechanism 3. The rotating table 11 is provided with a plurality of carrying positions, and the carrying positions are used to carry a load frame 100 and other load objects. A glass substrate 200 can be placed on the loading frame 100. The rotating support structure 2 is an annular structure, which is fixed on the base frame 12 and can rotate around the central axis of the rotating support structure 2 relative to the base frame 12. The rotating table 11 is supported on the rotating support structure 2 and rotates with the rotating support structure 2. The rotating drive mechanism 3 is connected to the rotating support structure, and is used to drive the rotating support structure 2 to rotate so as to drive the rotating table 11 to rotate.

[0045] In a specific implementation, the rotating bearing device may have a fixed loading position and unloading position. When the bearing position rotates to the loading position or the unloading position, the load can be placed in the bearing position. For example, two bearing positions may be provided on the rotating table 11, namely a first bearing position and a second bearing position. The first bearing position and the second bearing position are arranged relative to each other, and the loading position and the unloading position are arranged relative to each other. In actual applications, when there are no loads (such as a loading rack 100) at the first bearing position and the second bearing position of the rotating bearing device, and the first bearing position rotates to the loading position, the loading rack 100 loaded with a glass substrate 200 to be subjected to a subsequent process can be placed on the first bearing position (i.e., loading). Afterwards, the rotating drive mechanism 3 can drive the rotating support structure 2 to rotate, so as to drive the rotating table 11 to rotate through the rotating support structure 2, so that the first bearing position rotates to the unloading position, and the second bearing position rotates to the loading position.

[0046] At this time, the glass substrate 200 to be processed can be taken from the first loading position for subsequent processing (i.e., unloading), and some other loading racks 100 loaded with glass substrates 200 to be processed can be placed on the second loading position. When all the glass substrates 200 on the first loading position are taken away, the rotary drive mechanism 3 can drive the rotary support structure 2 to rotate, so as to drive the rotary table 11 to rotate through the rotary support structure 2, so that the first loading position is rotated to the loading position, and the second loading position is rotated to the unloading position. At this time, the glass substrate 200 to be processed can be taken from the second loading position for subsequent processing, and after the empty loading rack 100 on the first loading position is taken away, the loading rack 100 loaded with glass substrates 200 can continue to be placed on the first loading position. In this way, the loading and unloading of substrates 200 can be continuously performed by repeating the above actions. When the rotary support structure 2 rotates, the rotary support structure 2 can rotate relative to the base frame 12, and the base frame 12 does not rotate with the rotation of the rotary support structure 2.

[0047] The rotating bearing device provided in the embodiment of the present invention can increase the contact range of the rotating support structure 2 with the rotating table 11 and the base frame 12 respectively by making the rotating support structure 2 an annular structure, and enable the rotating support structure 2 to be in continuous contact with the rotating table 11 and the base frame 12 respectively, thereby improving the ability of the rotating support structure 2 to support the rotating table 11, and then improving the supporting capacity of the rotating bearing device, thereby making the rotating bearing device less prone to damage and improving the rotation stability.

[0048] Optionally, the rotation drive mechanism 3 may include a rotary drive mechanism.

[0049] In practical applications, the rotary drive structure can drive the rotary support structure 2 to rotate 180° along the first direction, so as to drive the rotary table 11 to rotate 180° along the first direction through the rotary support structure 2, so that the bearing position at the loading position is rotated to the unloading position, and the bearing position at the unloading position is rotated to the loading position. When the substrates 200 on the bearing position at the unloading position are all removed, the rotary drive structure can drive the rotary support structure 2 to rotate 180° along the second direction opposite to the first direction, so as to drive the rotary table 11 to rotate 180° along the second direction through the rotary support structure 2, so that the bearing position previously at the unloading position is rotated to the loading position, and the bearing position previously at the loading position is rotated to the unloading position.

[0050] like Figure 1-Figure 3 As shown, optionally, the rotating table 11 may include a first supporting plate, the base frame 12 may include a second supporting plate, the first supporting plate is located above the second supporting plate and opposite to the second supporting plate, and the rotating support structure 2 and the rotating drive mechanism 3 may both be arranged between the first supporting plate and the second supporting plate.

[0051] like Figure 1 and Figure 2 As shown, optionally, the rotation drive mechanism 3 can be arranged below the rotating table 11 .

[0052] Such a design can avoid the rotating drive mechanism 3 occupying the rotating table 11, thereby reducing the size of the rotating table 11 and the rotation radius, and then reducing the overall size of the rotating support device and the rotation radius. Then, a rotating support structure 2 with a smaller radius and lower cost can be selected, and a rotating drive mechanism 3 with lower power and lower cost can be selected, which can make the rotating support device less prone to damage, improve rotational stability, reduce occupied space, reduce rotational drive power requirements, and reduce costs.

[0053] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the rotating support structure 2 may include a first ring body 21, which is connected to the rotating table 11, and a first external tooth structure 211 is arranged on the periphery of the first ring body 21, and the rotating drive mechanism 3 may include a first driving member 31 and an active member 32, and a second external tooth structure 321 meshing with the first external tooth structure 211 is arranged on the periphery of the active member 32, and the first driving member 31 is connected to the active member 32, and is used to drive the first ring body 21 to rotate by driving the active member 32 to rotate.

[0054] In practical applications, the first driving member 31 can drive the active member 32 to rotate, so as to drive the first ring body 21 to rotate through the active member 32, thereby driving the rotating table 11 to rotate through the first ring body 21. By setting the first outer tooth structure 211 on the periphery of the first ring body 21 and the second outer tooth structure 321 on the periphery of the active member 32, the first ring body 21 and the active member 32 are meshed through the first outer tooth structure 211 and the second outer tooth structure 321 set on their respective peripheries, so that the active member 32 of the rotating drive mechanism 3 connected to the base frame 12 can be easily connected to the first ring body 21, and when the rotating bearing device is assembled and debugged, it is convenient to assemble and debug the rotating bearing device (for example, a larger operating space can be provided for adjusting the meshing backlash of the first outer tooth structure 211 and the second outer tooth structure 321), and during the use of the rotating bearing device, it is convenient to perform daily maintenance on the rotating bearing device (for example, it is convenient to apply grease to the first outer tooth structure 211 and the second outer tooth structure 321).

[0055] Optionally, the first ring body 21 and the rotating platform 11 may be in surface contact.

[0056] For example, the two surfaces of the first ring body 21 and the rotating table 11 that contact each other are both planes. Such a design can increase the contact area between the first ring body 21 and the rotating table 11, thereby further improving the ability of the rotating support structure 2 to support the rotating table 11, and then further improving the supporting ability of the rotating bearing device, thereby further making the rotating bearing device less prone to damage and improving the rotation stability.

[0057] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the rotating support structure 2 may further include a second ring body 22 , the second ring body 22 is connected to the base frame 12 , the first ring body 21 is connected to the second ring body 22 , and the first ring body 21 can rotate relative to the second ring body 22 .

[0058] In actual application, when the first ring body 21 is driven to rotate, the first ring body 21 is connected to the rotating table 11 and does not rotate relative to the rotating table 11, but rotates relative to the second ring body 22. The second ring body 22 is connected to the base frame 12 and does not rotate relative to the base frame 12, thereby realizing that the rotating support structure 2 is respectively connected to the rotating table 11 and the base frame 12, and can rotate relative to the base frame 12.

[0059] Optionally, the second ring body 22 and the base frame 12 may be in surface contact.

[0060] For example, the two surfaces of the second ring body 22 and the base frame 12 that contact each other are both planes. Such a design can increase the contact area between the second ring body 22 and the base frame 12, thereby further improving the ability of the rotating support structure 2 to support the rotating table 11, and then further improving the supporting ability of the rotating bearing device, thereby further making the rotating bearing device less prone to damage and improving the rotation stability.

[0061] In an embodiment of the present invention, a bearing may be disposed on the outer periphery of the second ring body 22 , and the first ring body 21 surrounds the second ring body 22 and is disposed in cooperation with the bearing.

[0062] In practical applications, the bearings can rotate relative to the first ring body 21 and the second ring body 22 respectively, so that the first ring body 21 can rotate relative to the second ring body 22 .

[0063] like Figure 2 As shown, in one embodiment of the present invention, the rotating bearing device may further include a protective cover 4 , and the protective cover 4 is arranged outside the rotating support structure 2 and the active component 32 .

[0064] On the one hand, the protective cover 4 can play a safety protection role to prevent people or foreign objects from intruding when the active part 32 and the first ring body 21 rotate, thereby improving the safety of the use of the rotating bearing device. On the other hand, it can play a sealing protection role to prevent the grease applied to the active part 32 and the first ring body 21 from being thrown out when the active part 32 and the first ring body 21 rotate, thereby reducing the pollution caused to the production environment.

[0065] like Figure 2 As shown, in one embodiment of the present invention, the rotation driving mechanism 3 may further include a speed reducing member 33 , and the first driving member 31 is connected to the active member 32 via the speed reducing member 33 .

[0066] Optionally, the first driving member 31 may include a rotary motor.

[0067] Optionally, the first driving member 31 may include a servo motor.

[0068] Optionally, the active member 32 may include a gear or a worm.

[0069] Optionally, the first ring body 21 may include a gear or a worm gear.

[0070] In practical applications, when the active member 32 includes a gear, the first ring body 21 may include a gear, and the meshing between the active member 32 and the first ring body 21 is similar to the meshing between two gears. When the active member 32 includes a worm, the first ring body 21 may include a worm wheel, and the meshing between the active member 32 and the first ring body 21 is similar to the meshing between a worm wheel and a worm.

[0071] like Figure 2 and Figure 4 As shown, in one embodiment of the present invention, the rotating bearing device may further include a positioning assembly 5 , and the positioning assembly 5 is used to position the rotating platform 11 .

[0072] In actual application, when the rotating table 11 stops rotating, the bearing position may not be aligned with the loading position and the unloading position. The rotating bearing device provided in the embodiment of the present invention can position the rotating table 11 after the rotating table 11 stops rotating by means of the positioning component 5, so that the bearing position can be aligned with the loading position and the unloading position, thereby improving the rotation accuracy and use stability of the rotating bearing device.

[0073] like Figure 4As shown, in one embodiment of the present invention, the positioning assembly 5 may include a positioning component 51 and a matching component 52, one of the positioning component 51 and the matching component 52 is connected to the rotating table 11, and the other is connected to the base frame 12, the positioning component 51 and the matching component 52 are arranged opposite to each other, and the positioning component 51 can approach or move away from the matching component 52, so as to be able to cooperate with the matching component 52 to position the rotation stop position of the rotating table 11 or separate from the matching component 52.

[0074] By connecting one of the positioning component 51 and the matching component 52 to the rotating table 11 and the other to the base frame 12, when the rotating table 11 stops rotating, the positioning component 51 can gradually approach the matching component 52 so as to gradually match with the matching component 52. In the process of the positioning component 51 gradually matching with the matching component 52, the rotating table 11 can be gradually rotated to a preset relative position with the base frame 12, so as to locate the position of the rotating table 11. When the rotating table 11 needs to rotate, the positioning component 51 gradually moves away from the matching component 52 so as to be separated from the matching component 52, so as to avoid the interference of the matching of the positioning component 51 and the matching component 52 on the rotation of the rotating table 11, so that the rotating table 11 can rotate smoothly.

[0075] like Figure 5 As shown, in one embodiment of the present invention, the positioning component 51 may include a second driving component 511 and a plug-in positioning component 512, and the mating component 52 is provided with a plug-in recess, and the radial dimension of the plug-in recess gradually decreases from one end of the plug-in recess close to the plug-in positioning component 512 to the other end away from the plug-in positioning component 512, and the second driving component 511 is connected to the plug-in positioning component 512, and is used to drive the plug-in positioning component 512 to approach or move away from the plug-in recess, so that the plug-in positioning component 512 can be matched with or separated from the plug-in recess.

[0076] In practical applications, when the rotating table 11 stops rotating, the second driving member 511 can drive the plug-in positioning member 512 to gradually approach the plug-in recess, so that the plug-in positioning member 512 gradually penetrates into the plug-in recess, thereby making the plug-in positioning member 512 cooperate with the plug-in recess. By gradually reducing the radial dimension of the plug-in recess from one end of the plug-in recess close to the plug-in positioning piece 512 to the end away from the plug-in positioning piece 512, the plug-in positioning piece 512 can smoothly enter the plug-in recess when the rotating table 11 deviates from the preset relative position with the base frame 12, and in the process of the plug-in positioning piece 512 gradually penetrating into the plug-in recess, the plug-in positioning piece 512 can contact the inner wall of the plug-in recess and squeeze the plug-in recess against each other, so that the plug-in positioning piece 512 and the plug-in recess can move relative to each other, so that the plug-in positioning piece 512 is gradually located in the center of the plug-in recess, and can drive the rotating table 11 to move in a small range relative to the base frame 12, so that the rotating table 11 is gradually rotated to a preset relative position with the base frame 12, thereby positioning the position of the rotating table 11. When the rotating platform 11 needs to rotate, the second driving member 511 can drive the plug-in positioning member 512 to gradually move away from the plug-in recess, so that the plug-in positioning member 512 gradually withdraws completely from the plug-in recess, thereby separating the plug-in positioning member 512 from the plug-in recess.

[0077] Optionally, the second driving member 511 may include a lifting cylinder.

[0078] Optionally, the cross-section of the plug-in recess may be V-shaped.

[0079] Optionally, the matching component 52 may be disposed on the surface of the rotating platform 11 facing the base frame 12 , and the end of the insertion recess having the largest radial dimension may face the base frame 12 .

[0080] Optionally, the second driving member 511 may be connected to the side of the base frame 12 , and the plug-in positioning member 512 may be disposed on the second driving member 511 .

[0081] like Figure 2 As shown, optionally, mating components 52 may be respectively provided at the diagonals of the rotating table 11 , the number of the positioning components 51 may be the same as the number of the mating components 52 , and the plurality of positioning components 51 and the plurality of mating components 52 may be provided in a one-to-one correspondence.

[0082] like Figure 4 As shown, optionally, the positioning component 51 may further include a connecting member 513 , and the second driving member 511 may be connected to the side of the base frame 12 via the connecting member 513 .

[0083] In one embodiment of the present invention, the plug-in positioning member 512 may include a plug-in positioning wheel (such as Figure 4 as shown) or insert the locating pin.

[0084] Optionally, the plug-in positioning wheel may include a roller.

[0085] like Figure 2 As shown, in one embodiment of the present invention, the rotating load-bearing device may further include a guide assembly 6, and the guide assembly 6 is used to guide the relative position between the transport equipment of the transport loading rack 100 and the load-bearing position.

[0086] In practical applications, the fully loaded loading rack 100 can be transported by means of the transport device and placed on the loading position at the loading position, and the empty loading rack 100 can be removed from the loading position at the loading position by means of the transport device. The relative position of the transport device and the loading position is guided by means of the guide assembly 6, so that when the transport device moves to the rotating load-bearing device, it can move to a preset relative position with the loading position, thereby improving the accuracy of the transport device in placing the fully loaded loading rack 100 on the loading position, and improving the accuracy of the transport device in removing the empty loading rack 100 from the loading position.

[0087] like Figure 2 As shown, in one embodiment of the present invention, the guide assembly 6 may include a first guide wheel 61 and a second guide wheel 62, and the first guide wheel 61 and the second guide wheel 62 are spaced apart and arranged opposite to each other.

[0088] like Figure 5 As shown, in actual application, the transport equipment can be a forklift 300, which has an upper double fork arm 301 and a lower double fork arm 302. The upper double fork arm 301 and the lower double fork arm 302 both have two parallel forks 303. The two forks 303 of the upper double fork arm 301 can carry the loading frame 100 and can be manually controlled to rise and fall. Rollers are respectively arranged under the two forks 303 of the lower double fork arm 302. The rollers arranged under the two forks 303 of the lower double fork arm 302 can contact the ground, thereby providing the forklift 300 with sufficient contact area with the ground.

[0089] By setting the first guide wheel 61 and the second guide wheel 62 spaced apart and opposite to each other, when the forklift 300 moves to the rotating load-bearing device, the lower double fork arm 302 of the forklift 300 can enter between the first guide wheel 61 and the second guide wheel 62, and the outer sides of the two fork arms 303 of the lower double fork arm 302 can contact the first guide wheel 61 and the second guide wheel 62 one by one, that is, the outer side of one fork arm 303 of the two fork arms 303 of the lower double fork arm 302 can contact the first guide wheel 61, and the outer side of the other fork arm 303 can contact the second guide wheel 62, so that the relative position of the forklift 300 and the load-bearing position is guided by the first guide wheel 61 and the second guide wheel 62.

[0090] In practical applications, the first guide wheel 61 and the second guide wheel 62 can be installed on the ground below the bearing position corresponding to the guide group.

[0091] like Figure 2 As shown, optionally, the number of the first guide wheels 61 and the number of the second guide wheels 62 can both be multiple, and the multiple first guide wheels 61 and the multiple second guide wheels 62 are all arranged at intervals in a third direction, and the third direction is perpendicular to the spacing direction of the first guide wheels 61 and the second guide wheels 62, and is parallel to the surface of the rotating table 11 for carrying the substrate 200.

[0092] Such a design can improve the guiding ability of the guiding component 6.

[0093] like Figure 2 As shown, optionally, a plurality of first guide wheels 61 and a plurality of second guide wheels 62 may be arranged opposite to each other.

[0094] In practical applications, a forklift 300 with an automated guided vehicle (AGV) function may also be used to achieve a precise travel route for the forklift 300. In this case, there is no need to set the guide assembly 6, but the forklift 300 with an automated guided vehicle function is more expensive.

[0095] In an embodiment of the present invention, the rotating load-bearing device may further include a limiting component, which is fixedly disposed on the rotating platform 11 and is used to limit the relative position of the load such as the loading frame 100 and the load position.

[0096] In practical applications, the relative position of the loading rack 100 and the load-bearing position is limited by means of a limiting component. Not only the relative position of the loading rack 100 and the load-bearing position can be limited, but also the relative position of the substrate 200 placed on the loading rack 100 and the load-bearing position can be limited. This can improve the position accuracy of the substrate 200 on the load-bearing position, thereby improving the accuracy of material unloading, and on the other hand, it can improve the position accuracy of the loading rack 100 on the load-bearing position, thereby improving the accuracy of transportation equipment such as a forklift 300 in removing the loading rack 100 from the load-bearing position.

[0097] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the limit assembly may include a plurality of limit groups 7, and the plurality of limit groups 7 are arranged in one-to-one correspondence with the plurality of load-bearing positions. The limit group 7 includes a first limit component 71 and a second limit component 72. The first limit component 71 and the second limit component 72 of the same limit group 7 are arranged at intervals on the rotating table 11, and are used to limit the opposite sides of the load frame 100 and other load-bearing objects in one-to-one correspondence.

[0098] In actual applications, the spacing direction of the first limiting component 71 and the second limiting component 72 can be perpendicular to the spacing direction of the first guide wheel 61 and the second guide wheel 62, and the spacing direction of the first limiting component 71 and the second limiting component 72 and the spacing direction of the first guide wheel 61 and the second guide wheel 62 can be parallel to the surface of the rotating table 11 for carrying the substrate 200, so that the relative position of the loading frame 100 and the substrate 200 placed on the loading frame 100 and the carrying position can be limited from two different directions, thereby improving the position accuracy of the substrate 200 and the loading frame 100 on the carrying position.

[0099] like Figure 3 As shown, optionally, the first limiting component 71 and the second limiting component 72 may be disposed on the surface of the rotating table 11 for carrying the substrate 200 .

[0100] Optionally, the distance between the first position-limiting component 71 and the second position-limiting component 72 may be greater than the size of the supported object in the spacing direction between the first position-limiting component 71 and the second position-limiting component 72 .

[0101] like Figure 3 As shown, optionally, the number of the first limiting components 71 and the number of the second limiting components 72 can both be multiple, and the multiple first limiting components 71 and the multiple second limiting components 72 are all arranged at intervals in a fourth direction, and the fourth direction is perpendicular to the spacing direction of the first limiting components 71 and the second limiting components 72, and is parallel to the surface of the rotating table 11 for supporting the substrate 200.

[0102] Such a design can improve the limiting ability of the limiting component.

[0103] like Figure 6 and Figure 7 As shown, optionally, the first limiting component 71 and the second limiting component 72 may both include a connecting portion 731, a limiting portion 732 and a bending portion 733, the connecting portion 731 is connected to the rotating table 11, the limiting portion 732 is connected to the connecting portion 731 and is bent relative to the connecting portion 731 for contacting the side of a load such as a loading rack 100, the bending portion 733 is disposed at the top of the limiting portion 732 and is bent relative to the limiting portion 732, and the bending portion 733 of the first limiting component 71 and the bending portion 733 of the second limiting component 72 are bent in directions away from each other.

[0104] In actual applications, the limiting portion 732 can be perpendicular to the connecting portion 731, so that the limiting portion 732 can limit the load such as the loading rack 100. By providing a bending portion 733 at the top of the limiting portion 732 and bending the bending portion 733 of the first limiting component 71 and the bending portion 733 of the second limiting component 72 in directions away from each other, the load such as the loading rack 100 can be easily dropped between the first limiting component 71 and the second limiting component 72.

[0105] In one embodiment of the present invention, the rotating load-bearing device may further include a regularization component, which is movably disposed on the rotating table 11 and is used to regularize the relative positions of the loads such as the loading rack 100 and the load positions.

[0106] In actual applications, after the loading rack 100 is placed on the carrying position, the relative position of the loading rack 100 and the carrying position can be regularized by moving the regularization component, thereby, on the one hand, improving the position accuracy of the substrate 200 on the carrying position, thereby improving the accuracy of unloading, and on the other hand, improving the position accuracy of the loading rack 100 on the carrying position, thereby improving the accuracy of transportation equipment such as forklifts 300 in removing the loading rack 100 from the carrying position.

[0107] like Figure 3 As shown, in one embodiment of the present invention, the organizing component may include a plurality of organizing groups 8, and the plurality of organizing groups 8 are arranged in one-to-one correspondence with the plurality of carrying positions. The organizing group 8 includes a first organizing component 81 and a second organizing component 82. The first organizing component 81 and the second organizing component 82 of the same organizing group 8 are arranged at intervals on the rotating table 11, and are used to organize the loads in one-to-one correspondence from the opposite sides of the loads such as the loading frame 100.

[0108] In actual applications, the first tidying component 81 and the second tidying component 82 can be movably arranged on the rotating table 11. When the loading rack 100 is placed on the carrying position, the first tidying component 81 and the second tidying component 82 can move relatively to each other so as to approach the loading rack 100 from two opposite sides of the loading rack 100 respectively, so as to tidy the loading rack 100 from two opposite sides of the loading rack 100.

[0109] like Figure 3 As shown, in one embodiment of the present invention, the first regularizing components 81 and the second regularizing components 82 of the same regularizing group 8 can be arranged at intervals on the diagonal line of the bearing position.

[0110] With such a design, when the first aligning component 81 and the second aligning component 82 are aligning the loading rack 100 from two opposite sides of the loading rack 100, the relative positions of the loading rack 100 and the substrate 200 placed on the loading rack 100 and the carrying position can be regulated from two directions perpendicular to each other at the same time, thereby improving the position accuracy of the substrate 200 and the loading rack 100 on the carrying position.

[0111] like Figure 3 As shown, in one embodiment of the present invention, at least one of the first organizing component 81 and the second organizing component 82 includes a third driving component 811, a first organizing portion 812 and a second organizing portion 813, and the third driving component is connected to the first organizing portion 812 and the second organizing portion 813, respectively, and is used to drive the first organizing portion 812 and the second organizing portion 813 to be close to or away from two adjacent sides of a carrier such as a loading rack 100 in a one-to-one correspondence, so that the first organizing portion 812 and the second organizing portion 813 are in contact with two adjacent sides of the carrier in a one-to-one correspondence or are separated from the carrier; and / or, the first organizing component 81 and the second organizing portion 813 are in contact with two adjacent sides of the carrier in a one-to-one correspondence. At least one of the organizing parts 82 includes a fourth driving member 821, a fifth driving member 822, a third regularizing part 823 and a fourth regularizing part 824, the fourth driving member 821 is connected to the third regularizing part 823, the fifth driving member 822 is connected to the fourth regularizing part 824, the fourth driving member 821 and the fifth driving member 822 are used to drive the third regularizing part 823 and the fourth regularizing part 824 one-to-one to approach or move away from two adjacent sides of a carrier such as the loading rack 100, so that the third regularizing part 823 and the fourth regularizing part 824 are in contact with two adjacent sides of the carrier or are separated from the carrier.

[0112] Specifically, if Figure 3As shown, the first regularizing component 81 and the second regularizing component 82 are arranged at intervals on the diagonal line of the bearing position, the first regularizing component 81 includes a third driving member 811, a first regularizing portion 812 and a second regularizing portion 813, and the second regularizing component 82 includes a fourth driving member 821, a fifth driving member 822, a third regularizing portion 823 and a fourth regularizing portion 824. In actual application, when the loading rack 100 is placed on the carrying position, the third driving member 811 can drive the first regularizing part 812 and the second regularizing part 813 to approach the loading rack 100 from one corner of the loading rack 100, so that the first regularizing part 812 and the second regularizing part 813 are close to the adjacent two sides of the loading rack 100 in a one-to-one manner. At the same time, the fourth driving member 821 and the fifth driving member 822 can drive the third regularizing part 823 and the fourth regularizing part 824 to approach the loading rack 100 from the other corner of the loading rack 100 in a one-to-one manner, so that the third regularizing part 823 and the fourth regularizing part 824 are close to the other adjacent two sides of the loading rack 100 in a one-to-one manner, thereby using the first regularizing part 812, the second regularizing part 813, the third regularizing part 823 and the fourth regularizing part 824 to regularize the relative positions of the loading rack 100 and the substrate 200 placed on the loading rack 100 and the carrying position from two directions perpendicular to each other.

[0113] In one embodiment of the present invention, the rotating bearing device may further include a floating bearing assembly, and the floating bearing assembly is used to float the bearing objects such as the loading rack 100 .

[0114] By floating the loading rack 100 with the floating loading assembly, the loading stability of the loading rack 100 and the substrate 200 placed on the loading rack 100 can be improved.

[0115] like Figure 1 and Figure 3 As shown, in one embodiment of the present invention, the floating bearing assembly may include multiple floating bearing groups, and the multiple floating bearing groups are arranged in a one-to-one correspondence with the multiple bearing positions. The floating bearing group includes multiple floating bearing components 91, and the multiple floating bearing components 91 of the same floating bearing group are arranged at intervals in the corresponding bearing positions for jointly floatingly bearing the load frame 100 and other load-bearing objects at the corresponding bearing positions.

[0116] like Figure 3 As shown, for example, the floating bearing group may include four floating bearing components 91. In actual applications, the four floating bearing components 91 can support the four corners of the loading rack 100 one by one. By floatingly supporting the loading rack 100 together with multiple floating bearing components 91, the bearing stability of the loading rack 100 and the substrate 200 placed on the loading rack 100 can be further improved.

[0117] In summary, the rotating bearing device provided by the embodiment of the present invention can improve the supporting capacity of the rotating bearing device, thereby making the rotating bearing device less prone to damage and improving the rotational stability.
