Description

Technical Field

[0001] This utility model relates to the field of material placement platform technology, specifically an adaptive floating material placement platform. Background Technology

[0002] In an automated logistics system, AGVs are responsible for transporting trays from upstream equipment to downstream workstations. During the transport process, the trays are first placed on a transfer platform for temporary storage, and then the robotic arm picks up the trays and takes them to the downstream workstation for processing.

[0003] Existing transfer platforms typically have guides to help trays fall to the center of the platform. However, due to the deviation in the placement of the trays each time, the trays are prone to tilting during placement, making it difficult for them to be properly centered on the loading plate. When the robotic arm grasps the trays, the inaccurate position of the trays requires repeated adjustments to the grasping position, which affects efficiency.

[0004] Based on this, an adaptive floating material placement platform is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adaptive floating material placement platform that can automatically center and maintain the balance of the tray, which is beneficial for subsequent robotic arm grasping.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adaptive floating material placement platform, comprising:

[0007] A pair of auxiliary connecting plates, a pair of support plates are fixed together on the pair of auxiliary connecting plates, a load plate is provided on the support plate, and front and rear hard limit plates and left and right hard limit plates are fixed on the load plate. The front and rear hard limit plates and left and right hard limit plates can be used for limitation, which facilitates the subsequent grasping of the robotic arm.

[0008] A tension spring, one end of which is connected to the carrying plate and the other end of which is connected to the support plate, works in conjunction with the ball joint assembly to keep the carrying plate balanced;

[0009] The omnidirectional ball assembly is mounted on the support plate. The carrier plate is provided with a guide plate corresponding to the omnidirectional ball assembly. The side of the guide plate that contacts the omnidirectional ball assembly is concave. The omnidirectional ball assembly slides on the concave surface of the guide plate. Under the interaction force of the tension spring, the omnidirectional ball assembly slides back to the bottom of the concave surface along the contour of the guide plate and remains stationary after reaching the fixed position each time.

[0010] Furthermore, each end of the pair of auxiliary connecting plates is fixed with a mounting bracket, and the four mounting brackets are respectively fixed to both sides of the pair of support plates. The bottom surface of the mounting bracket is fixed with a support frame, which provides auxiliary support to the entire platform and improves its stability.

[0011] Furthermore, the carrier plate has a left and right hard limiting plate and two front and rear hard limiting plates symmetrically distributed with the center of the left and right hard limiting plates as the reference. The left and right hard limiting plates are perpendicular to the front and rear hard limiting plates. The two left and right hard limiting plates and the four left and right hard limiting plates form a rectangular accommodating space, which confines the Tray disk on the carrier plate.

[0012] Furthermore, the number of tension springs is four, and they are respectively arranged on the two support plates, which can keep the tray disk balanced.

[0013] Furthermore, each of the support plates has four omnidirectional ball assemblies, which are symmetrically arranged on the support plate to provide multi-point support for the load plate, thereby enhancing its stability.

[0014] Furthermore, the omnidirectional ball assembly includes a mounting base fixed to the support plate, and an omnidirectional ball is provided on the mounting base to fit against the guide plate. When the omnidirectional ball slides on the concave surface of the guide plate, under the interaction force of the tension spring, the omnidirectional ball slides back to the bottom of the concave surface along the contour of the guide plate, and remains stationary after reaching the fixed position each time, so that the loading plate can maintain balance and remain stationary.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This adaptive floating material placement platform allows the tray to slide freely under the action of the omnidirectional ball assembly after the tray is lowered. It is also equipped with tension springs that interact with the omnidirectional ball assembly, so that the tray is centered and can maintain balance, which facilitates subsequent gripping by the robotic arm.

[0022] 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.

[0023] Please see Figure 1-4 An adaptive floating material placement platform in this embodiment includes a pair of auxiliary connecting plates 1, a pair of support plates 2 are fixed on the pair of auxiliary connecting plates 1, a load plate 3 is provided on the support plate 2, and front and rear hard limiting plates 4 and left and right hard limiting plates 5 are fixed on the load plate 3.

[0024] When the tray is placed on the carrier plate 3, it can be limited by the front and rear hard limit plates 4 and the left and right hard limit plates 5, which facilitates the subsequent grasping by the robotic arm.

[0025] Mounting brackets 6 are fixed at both ends of a pair of auxiliary connecting plates 1. The four mounting brackets 6 are fixed to both sides of a pair of support plates 2 respectively. The support plates 2 are fixed by the mounting brackets 6. The bottom surface of the mounting brackets 6 is fixed with a support frame 7. The support frame 7 provides auxiliary support for the entire platform and improves its stability.

[0026] The carrier plate 3 has a left and right hard limiting plate 5 and two front and rear hard limiting plates 4 symmetrically distributed with the center of the left and right hard limiting plate 5 as the reference. The left and right hard limiting plates 5 and the front and rear hard limiting plates 4 are perpendicular to each other. The two left and right hard limiting plates 5 and the four left and right hard limiting plates 5 form a rectangular receiving space. Since the front and rear hard limiting plates 4 and the left and right hard limiting plates 5 form a rectangular receiving space, the tray can be limited on the carrier plate 3. The inner side of the limiting plates can be set as a slope, which is conducive to guiding the tray into the rectangular receiving space on the carrier plate 3.

[0027] When the AGV vehicle retrieves the tray for transfer, it needs to be placed on a transfer platform. The tray can be placed between the front and rear hard limit plates 4 and the left and right hard limit plates 5 of the loading plate 3. The tray will fall naturally onto the loading plate 3 by gravity.

[0028] However, the tray is prone to tilting when placed, which makes it difficult to center the tray properly on the carrier plate 3. When the robotic arm grasps the tray, the inaccurate position of the tray requires repeated adjustments, affecting efficiency. This platform can automatically center the tray and maintain its balance, which is beneficial for subsequent robotic arm grasping.

[0029] As for how to implement the above operation, in this embodiment, the carrying plate 3 and the support plate 2 are connected by a tension spring 8. One end of the tension spring 8 is connected to the carrying plate 3 and the other end is connected to the support plate 2. The support plate 2 is provided with multiple universal ball assemblies 9, and the carrying plate 3 is provided with guide plates 10 corresponding to the universal ball assemblies 9. After the tray is put down, the carrying plate 3 can slide freely under the action of the universal ball assemblies 9. The tension spring 8 interacts with the universal ball assemblies 9, and finally the tray is in a centered state and can maintain balance.

[0030] Since a pair of auxiliary connecting plates 1 form two support plates 2 into a whole, and the number of tension springs 8 is preferably four, which are respectively arranged on the two support plates 2, the tray can be kept in balance.

[0031] Each support plate 2 has four omnidirectional ball assemblies 9, which are symmetrically arranged on the support plate 2. The omnidirectional ball assemblies 9 provide multi-point support for the load plate 3, making it more stable.

[0032] As a specific structure of the universal ball assembly 9, the universal ball assembly 9 includes a mounting base 91 fixed on the support plate 2, and a universal ball 92 that fits against the guide plate 10 is provided on the mounting base 91. The side of the guide plate 10 that contacts the universal ball 92 is concave. When the universal ball 92 slides on the concave surface of the guide plate 10, under the interaction force of the tension spring 8, the universal ball 92 slides back to the bottom of the concave surface along the contour of the guide plate 10, and remains stationary after reaching the fixed position each time, so that the carrying plate 3 can maintain balance and remain stationary.

[0033] In summary, when using this utility model, the tray needs to be placed on a transfer platform for transfer when the AGV picks up the tray. The tray is placed between the front and rear rigid limit plates 4 and the left and right rigid limit plates 5 of the carrier plate 3. The tray will fall naturally onto the carrier plate 3 by gravity. Under the action of the universal ball assembly 9, the carrier plate 3 can slide freely. The tension spring 8 interacts with the universal ball assembly 9. Finally, the tray is in a centered state and can maintain balance, which is convenient for the subsequent robotic arm to grasp.
