[0003] With the increasing degree of automation, at present, the transfer and loading of workpieces are mostly involved in automated turnover, such as through robotic arms, multi-axis picking mechanisms, etc. Since the positioning structure of the jig is relatively fixed, the accuracy of the loading position of the turnover mechanism is very high, and the situation where the workpiece cannot be loaded in place due to the lack of alignment accuracy often occurs during operation.

[0004] In response to this situation, a vision recognition mechanism is generally used to cooperate with the turnover mechanism for positioning, and corresponding high-precision displacement control is performed. Equipping with a vision guidance system undoubtedly increases the cost, and at the same time, the requirements for the production line space and light source are also relatively high, which undoubtedly leads to a relatively high construction cost of the entire production line.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0033] The following further elaborates on the present application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the relevant utility model and not for limiting the utility model. Additionally, it should be noted that for the sake of description, only parts related to the relevant utility model are shown in the drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0034] The present utility model provides a floating centering device for supporting, positioning, and carrying a carrier. The bottom of the carrier is provided with a plurality of positioning convex columns having guiding conical ends. The carrier belongs to the prior art, and its drawings are omitted in this case.

[0035] As Figures 1 to 6As shown in the figure, the floating centering device includes a supporting platform 1 and a floating centering mechanism 2 arranged on the supporting platform 1.

[0036] The floating centering mechanism 2 includes a supporting plate 3, a first floating plate 4 arranged on the supporting plate 3 with horizontal bidirectional linear floating displacement, and a second floating plate 5 arranged on the first floating plate 4 with horizontal bidirectional linear floating displacement. The linear displacement direction of the first floating plate 4 is perpendicular to the linear displacement direction of the second floating plate 5.

[0037] Positioning channels 6 corresponding to a number of positioning studs are respectively arranged on the first floating plate 4 and the second floating plate 5.

[0038] In the initial state without external force of the floating centering mechanism 2, the positioning channels on the first floating plate are concentrically aligned with the positioning channels on the second floating plate one by one.

[0039] Specific implementation process and principle description:

[0040] In the initial state without external force of the floating centering mechanism 2, the positioning channels on its first floating plate are concentrically aligned with the positioning channels on the second floating plate one by one.

[0041] When loading the carrier, it is automatically loaded through a robotic arm and a multi-axis transfer table. There are certain loading position deviations for the carrier. At this time, when the positioning studs are docked into the corresponding positioning channels 6 under the deviation condition, it will cause the second floating plate 5 and even the first floating plate 4 to generate corresponding displacement deviations, and the deviation displacement will generate corresponding elastic floating extrusion amounts.

[0042] After the carrier loading is completed, the transfer equipment such as the robotic arm releases the carrier and exits. At this time, the first floating plate 4 and the second floating plate 5 will adjust the position of the carrier under the action of the elastic reset floating force, so as to meet the floating centering requirement.

[0043] In a specific embodiment, a central positioning stud with a guiding cone end is arranged at the bottom of the carrier; central positioning channels 7 matching the central positioning stud are respectively arranged on the first floating plate, the second floating plate, and the supporting plate.

[0044] In the initial state without external force of the floating centering mechanism, the central positioning channels of the first floating plate, the second floating plate, and the supporting plate are concentrically aligned.

[0045] Specifically, during the carrier loading, the deviation of the central positioning convex post will correspond to the positioning channels of the first floating carrier plate and the second floating carrier plate. There will be a deviation displacement between the central positioning convex post and the central positioning channel 7. When the carrier is released, the first floating carrier plate and the second floating carrier plate will float and reset. During the reset process, there will be a relative position correction between the central positioning convex post and the central positioning channel 7, and the central positioning convex post will be centered and inserted into the central positioning channel 7, thus achieving reliable and accurate centering.

[0046] In a specific embodiment, the first floating carrier plate 4 is slidably arranged on the supporting carrier plate 3, and two first floating parts 40 with opposite floating directions are arranged between the first floating carrier plate 4 and the supporting carrier plate; the second floating carrier plate is slidably arranged on the first floating carrier plate, and two second floating parts 50 with opposite floating directions are arranged between the second floating carrier plate and the first floating carrier plate.

[0047] Specifically, that is, through two first floating parts 40 with opposite floating directions and two second floating parts 50 with opposite floating directions, the respective two-way floating compression is realized. Taking the first floating part 40 as an example, when there is elastic compression towards the first floating part 40, the other opposite first floating part 40 generates elastic tension. When the carrier is released, the elastically compressed first floating part 40 generates reverse reset, and the other first floating part 40 generates a pulling force, so the floating reset is more reliable.

[0048] In a specific embodiment, a plurality of outer peripheral limiting protrusions 500 are arranged on the second floating carrier plate 5.

[0049] The limiting protrusion 500 is used for the pre-positioning of the carrier during loading. Floating correction can only be achieved within this range. When the carrier is loaded beyond this range, its deviation cannot be corrected. This design is for the protection of the centering range. Loading materials beyond this interval indicates a loading error, and the loading position of the loading equipment needs to be corrected.

[0050] In a specific embodiment, the supporting carrier platform 1 includes a supporting carrier frame 11 and a lifting carrier platform 12 with lifting displacement arranged on the supporting carrier frame 11, and the supporting carrier plate is arranged on the lifting carrier platform.

[0051] Specifically, in some practical applications, the lifting displacement drive of the loaded carrier needs to be satisfied. Therefore, the design of the lifting carrier platform 12 on the supporting carrier frame 11 is adopted to meet its lifting drive operation requirements.

[0052] In a specific embodiment, the supporting carrier frame 11 includes a supporting base plate 111. A lifting drive source 112 and a lifting guiding mechanism 113 are arranged at the bottom of the supporting base plate 111. The driving end of the lifting drive source and the guiding end of the lifting guiding mechanism respectively penetrate the supporting base plate and are connected to the lifting carrier platform.

[0053] Thus, the requirements for the lifting and guiding stroke accuracy and reliability are met.

[0054] In a specific embodiment, a rotating base 8 with rotational displacement is provided on the lifting stage 12, and the supporting plate is arranged on the rotating base. A rotating bushing 81 with rotational displacement is provided on the rotating base 8, and a rotating drive source 82 that is rotationally and drivably connected to the rotating bushing. The supporting plate is detachably arranged on the rotating bushing.

[0055] That is, the rotating drive source 82 can drive the rotation of the rotating bushing 81 to meet the rotational adjustment angle requirements of the floating centering mechanism 2, making its application more flexible. With the detachable design of the supporting plate, it is convenient to change the type.

[0056] From the above description, it can be found that a floating centering device of the present invention meets the floating centering requirements after the carrier is mounted, reduces the requirements for feeding accuracy, and the floating centering is efficient and smooth. It can achieve precise centering and ensure the accurate and reliable position of the carrier. It has lifting and rotational adjustment displacements to meet the functional requirements of lifting and rotational alignment of the work station, with more flexible application and smoother adjustment operation.

[0058] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
