[0031] The utility model provides a bearing distribution device 100, comprising a transfer platform 1, wherein a bearing positioning structure is arranged on the transfer platform 1, and the bearing positioning structure can position the yaw bearing on the transfer platform to determine the position of the yaw bearing on the transfer platform 1. During the transportation process of the yaw bearing, the yaw bearing is first positioned on the transfer platform 1, and then the transfer platform 1 is directly transferred between different workstations, which can ensure the posture of the yaw bearing during the transportation process, so that different workstations can take and place the yaw bearing in the same posture, thereby improving the operation efficiency of the entire distribution system, and there is no need to re-perform posture recognition before taking and placing materials.

[0032] It should be noted that, in the present invention, the bearing positioning structure is used to position the bearing on the bearing surface, and the yaw bearing is often arranged in a ring shape with a bearing hole formed in the center, and a plurality of positioning holes are also penetrated on the bearing.

[0033] The bearing positioning structure has various implementations, for example, a bearing seat is provided to extend into the bearing hole to position the yaw bearing.

[0034] In the embodiment provided by the utility model, a positioning shaft hole 11 is formed on the bearing surface; the bearing delivery device 100 also includes a mounting pin, which is movable to be inserted into the positioning hole of the yaw bearing and detachably mounted to the positioning shaft hole 11; the positioning shaft hole 11 and the mounting pin together form the bearing positioning structure. In this embodiment, in order to facilitate the fixing of the yaw bearing, the positioning shaft hole is provided on the bearing surface. After the yaw bearing is placed on the bearing surface, the mounting pin is inserted into the positioning hole corresponding to the positioning hole of the yaw bearing and positioned in the positioning shaft hole 11, so that the yaw bearing is positioned in a fixed position, which can ensure that the entire yaw bearing will not be displaced during the transportation process.

[0035] Further, in this embodiment, the positioning shaft hole 11 and the mounting pin shaft together form a positioning group, and the positioning group is provided in plurality, and the plurality of positioning groups are arranged at intervals along the circumference of the transfer platform. In this embodiment, the plurality of positioning groups are arranged at intervals along the circumference to form multi-point positioning, so as to simultaneously position the yaw bearing in multiple directions, ensure the precise positioning of the yaw bearing, and avoid slight deviations that may occur during single-point positioning.

[0036] It should be noted that in the specific embodiment provided by the utility model, there are three positioning groups, and the three positioning groups are arranged at intervals along the circumference of the transfer platform 1 to form triangular positioning. While having fewer positioning points, stable and accurate positioning can be guaranteed to avoid deviation in the position of the yaw bearing.

[0037] In addition, in another embodiment provided by the utility model, the positioning shaft hole 11 and the mounting pin shaft jointly form a positioning group, and the positioning group is provided in plurality, and the plurality of positioning groups are arranged at intervals along the radial direction of the transfer platform 1. In this embodiment, the plurality of positioning groups are arranged at intervals along the radial direction of the transfer platform 1, so that the positioning group can position yaw bearings of different diameters when the axis position is the same, so that more yaw bearings can be adapted.

[0038] In a specific embodiment provided by the present invention, a plurality of positioning shaft holes 11 are sequentially arranged on the bearing surface along the radial direction, so as to facilitate positioning of the yaw bearings of different diameters at the same axial position.

[0039] In an embodiment provided by the utility model, there are multiple positioning groups, and the multiple positioning groups are arranged at intervals along the circumference of the transfer platform 1 to form multi-point positioning; at the same time, the multiple positioning groups arranged at intervals along the circumference form a diameter positioning group, and there are multiple diameter positioning groups, and the multiple diameter positioning groups are arranged at intervals along the radial direction of the transfer platform to adapt to yaw bearings of different diameters.

[0040] On the other hand, in this embodiment, a plurality of bearing brackets 12 are formed on the transfer platform 1, and the plurality of bearing brackets 12 are arranged at intervals along the circumference of the transfer platform, and the upper end surfaces of the plurality of bearing brackets 12 jointly form the bearing surface. In this embodiment, the yaw bearing is suspended by the bearing brackets 12, so that only a part of it is supported by the bearing surface, which is convenient for placing or removing the yaw bearing.

[0041] In this embodiment, three support brackets 12 are provided to form a three-point support, which provides stable support and has low cost.

[0042] It should be noted that, in the present embodiment, the positioning shaft hole is provided on the upper end surface of the supporting bracket 12 , so as to facilitate positioning of the yaw bearing on the supporting bracket 12 .

[0043] During the conveying process of the yaw bearing, the conveying position of the electric cart is often controlled manually, resulting in low conveying accuracy of the entire electric cart. However, the cost is too high when high-precision chip positioning is used.

[0044] Therefore, in the present invention, a tool positioning structure is also formed on the transfer platform 1, and the tool positioning structure is used to position the transfer platform to the workstation bearing surface. In this embodiment, the transfer platform 1 is directly positioned by mechanical structure through the tool positioning structure, which ensures the transfer accuracy of the transfer platform 1. At the same time, there is no need to set up too many electronic positioning devices, thereby reducing the design cost of the transfer platform 1.

[0045] It should be noted that there are multiple implementations of the tooling positioning structure, for example, a baffle is directly provided on the transfer platform 1, and after moving to a preset position, the baffle abuts against a matching plate at the work station to achieve positioning of the transfer platform 1.

[0046] Specifically, in this embodiment, a positioning block and a matching groove that cooperate with each other are provided between the transfer platform 1 and the workstation bearing surface, and the positioning block is installed in the matching groove. One of the positioning block and the matching groove is provided on the transfer platform, and the other is provided at an external workstation, wherein the positioning block or the matching groove on the transfer platform 1 forms the tooling positioning structure. In this embodiment, mechanical positioning is formed by the mutually cooperating positioning block and the matching groove. After the transfer platform 1 moves into place, the positioning block will be installed in the matching groove to realize mechanical hard limiting. The limiting method is simple and reliable, and the cost is low, and there is no need to make major changes to the existing distribution system.

[0047] On the other hand, see Figure 2 In this embodiment, the transfer platform 1 includes a platform body 13 and support legs 14; the platform body 13 forms the bearing surface; the support legs 14 are provided at the lower end of the platform body 13 to support the platform body 13; wherein the tooling positioning structure is provided on the support legs 14. In this embodiment, in order to facilitate the taking and placing of the transfer platform 1, the transfer platform 1 is lifted by the support legs 14, so that external transfer equipment such as forklifts can directly extend between the platform body 13 and the bottom surface to lift the transfer platform 1, thereby facilitating the transfer of the transfer platform 1.

[0048] It should be noted that, in the present embodiment, the tooling positioning structure is disposed on the supporting legs, so as to facilitate positioning of the transfer platform when the supporting legs 14 support the platform body 13 .

[0049] In the specific embodiment provided by the utility model, the transfer platform 1 includes a platform body 13 and a supporting leg 14, the lower end surface of the supporting leg 14 is formed with the matching groove, and the positioning block is formed at the corresponding work station in the outside world. During transportation, the transfer platform 1 is lifted by external equipment and moved to the work station. After moving to the corresponding position, the transfer platform 1 is lowered to align with the positioning block, so that the transfer platform 1 is positioned at the preset work station. The structure is simple and reliable, without the need to use too many electronic components, thereby reducing the use and manufacturing costs of the transfer platform 1 and facilitating use.

[0050] In the existing transportation process of the yaw bearing, an automatic guided vehicle is used as a transfer device to transfer the transfer platform to other workstations. The automatic guided vehicle moves along a preset route and performs corresponding actions at corresponding positions.

[0051] Therefore, in order to facilitate the automatic guided vehicle to accurately guide to the transfer platform 1, in this embodiment, a transport guide structure is also formed on the transfer platform 1, and the transport guide structure is used to guide the external automatic guided vehicle to obtain the position of the transfer platform. In this embodiment, by setting a transport guide structure to ensure that the automatic guided vehicle quickly and accurately locates the transfer platform 1 and performs the transfer, it can be avoided that the automatic guided vehicle will not deviate from the force position or force angle when transferring the transfer platform, causing the transfer platform 1 to shake or fall off during transfer, thereby ensuring the transfer safety of the transfer platform 1.

[0052] It should be noted that there are many implementation methods for the transport guide structure, such as setting up an active laser radar to continuously send signals to the automatic guided vehicle to facilitate the automatic guided vehicle to find it, or setting a positioning point on the transfer platform 1 and positioning it through visual recognition by the automatic guided vehicle.

[0053] Specifically, in this embodiment, the bearing delivery device 100 also includes two scanning baffles 2 arranged at intervals, and the two scanning baffles 2 are arranged on the transfer platform 1, and a scanning gap for the automatic guided vehicle to identify is formed between the two scanning baffles. In this embodiment, two scanning baffles 2 arranged at intervals are arranged on the transfer platform 1. During operation, the automatic guided vehicle will actively generate a laser signal, and the laser signal will pass through the scanning gap between the two scanning baffles 2. Once the position deviation occurs, the laser signal will hit the scanning baffle 2 and generate reflection, so that the laser cannot directly pass through the scanning gap. The automatic guided vehicle determines that there is a position deviation, and then it can be adjusted according to the specific shape and position of the laser. In this embodiment, a passive baffle is used for position guidance, which reduces the transfer cost of the transfer platform 1 and ensures the transfer accuracy of the transfer platform 1 during the transfer process.

[0054] In the embodiment provided by the present utility model, the transfer platform 1 includes the platform body 13 and the supporting legs 14, and the two scanning baffles 2 are arranged on the supporting legs 14 to facilitate the automatic guided vehicle to actively find the transfer platform.

[0055] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
