Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically a feeding base with multi-directional adjustment function. Background Technology

[0002] In the fields of automated production and logistics transportation, loading platforms, as key equipment for carrying and conveying materials, are widely used in various production lines and warehousing systems. As standardized material carrying units, pallets often vary in specifications (such as height and flatness) due to differences in materials, production batches, or usage scenarios. This creates an urgent need for loading platforms that can adapt to various pallets.

[0003] Existing loading platforms typically only have a single conveying function, making it difficult to adjust the height of the placed pallets. Due to differences in pallet thickness or deformation caused by long-term use, pallets of different specifications are prone to tilting and wobbling when placed on the platform, affecting the accuracy of subsequent robotic gripping or material transfer. While some improved platforms attempt to add height adjustment structures, they mostly use a whole-body lifting method, which cannot flexibly adapt to local differences in pallets, making it difficult to solve the adverse effects of localized pallet deformation. Furthermore, the adjustment accuracy is low, and the operation is cumbersome, failing to meet the needs of efficient and precise adaptation to various pallets in actual production.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] A loading platform with multi-directional adjustment function includes a platform frame and a pallet. A horizontal conveying mechanism is provided on the platform frame. The horizontal conveying mechanism includes a drive motor, a transmission chain and a sprocket assembly. The transmission chain is arranged along the length of the platform frame and connected to the pallet. The drive motor drives the transmission chain to rotate through the sprocket assembly, thereby driving the pallet to move horizontally.

[0007] The tray has at least four sets of height adjustment components. Each set of height adjustment components is a mating structure including a bolt rod and a nut. The bolt rod is vertically inserted into a preset mounting hole in the tray. The nut is threaded into the bolt rod and abuts against the side of the tray. The top of the bolt rod protrudes from the upper surface of the tray to form a support part.

[0008] Each height adjustment assembly's bolt rod can independently change the height of its support protruding from the upper surface of the tray by rotating relative to the nut.

[0009] As a further embodiment of this utility model: the transmission chain is fixedly connected to the bottom of the tray via a connecting block;

[0024] 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.

[0025] Please see Figure 1-3 In this embodiment of the utility model, a feeding platform with multi-directional adjustment function is composed of a platform frame 1, a tray 2, a horizontal conveying mechanism 3, and a height adjustment component 4. The specific structure and cooperation relationship of each component are as follows:

[0026] The base frame 1 provides rigid support for the overall structure. Two parallel guide rails are fixed along the length of its top. The guide rails have a grooved cross-section and are used to guide and constrain the horizontal movement of the pallet 2. The horizontal conveying mechanism 3 is installed on the base frame 1 and includes a drive motor, a transmission chain, a drive sprocket, and a driven sprocket. The drive sprocket and the driven sprocket are respectively installed at both ends of the base frame 1 through bearing seats. The transmission chain is sleeved between the drive sprocket and the driven sprocket and kept taut. The output shaft of the drive motor is connected to the drive sprocket through a coupling to form a complete power transmission path.

[0027] The tray 2 is a rectangular plate structure with two sets of sliders fixed to its bottom by bolts. The cross-sectional shape of the sliders matches the groove of the guide rail, and the sliders are embedded in the guide rail and can slide along the length of the rail. A connecting block is welded to the center line of the bottom of the tray 2. The connecting block is located between the two sets of sliders and its height is lower than the bottom of the sliders to avoid contact with the base frame 1. The side of the connecting block away from the tray 2 is fixed to a link of the transmission chain by a pin. When the drive motor drives the drive sprocket to rotate, the transmission chain pulls the tray 2 to make horizontal reciprocating motion along the guide rail through the connecting block.

[0028] The four corners of tray 2 extend outward to form rectangular connecting ends 8. Each connecting end 8 has a vertically penetrating mounting hole. The mounting hole is a smooth hole with a diameter 0.5-1mm larger than the outer diameter of bolt rod 5 to ensure smooth raising and lowering of bolt rod 5 without significant radial offset. Bolt rod 5 passes through the mounting hole, and the outer wall of bolt rod 5 is machined with external threads to fit the mounting hole with clearance. Nut 6 is fitted at the lower part of bolt rod 5. Nut 6 is threaded to bolt rod 5, and the upper surface of nut 6 fits against the lower surface of connecting end 8. When nut 6 is tightened, the height position of bolt rod 5 is locked by the friction between nut 6 and connecting end 8.

[0029] A circular support 7 is welded to the top of the bolt rod 5. The diameter of the support 7 is larger than that of the bolt rod 5, and its top surface is machined with a grid-like anti-slip texture for direct contact with and support of the pallet. Four sets of height adjustment components 4 correspond to the four corners of the pallet 2, and the top surfaces of the support 7 are on the same initial plane. The outer wall of the bolt rod 5 is printed with height markings along the axial direction. The smallest unit of the markings is 1 mm, and the starting zero point is aligned with the upper surface of the connecting end 8. The marking value represents the vertical distance between the top surface of the support 7 and the upper surface of the connecting end 8. The height of the support 7 protruding from the upper surface of the pallet 2 can be read intuitively by observing the markings.

[0030] When the pallet is placed on the four support sections 7, if the pallet tilts due to uneven thickness or local deformation, the height of the support section 7 can be adjusted by individually rotating the corresponding bolt rod 5 (or nut 6): rotating the bolt rod 5 clockwise moves the support section 7 upward; rotating it counterclockwise moves the support section 7 downward until the upper surface of the pallet reaches a horizontal state. In practical applications, after the pallet is placed on the support section 7 of the pallet 2, the horizontal conveying mechanism 3 can drive the pallet 2 and the pallet to move along the length of the base frame 1 to the designated position. For pallets of different specifications (such as wooden pallets and plastic pallets of different heights), the support section 7 can be raised and lowered as a whole by synchronously adjusting the four sets of height adjustment components 4 to adapt to the bottom height of the pallet; for pallets that have undergone local deformation due to long-term use (such as a corner sinking), the height of the support section 7 at the corresponding corner can be adjusted individually to compensate for the deformation and ensure that the pallet always maintains a horizontal posture, which is convenient for the robot to grab or transfer the materials on the pallet.

[0031] More specifically, in practical applications, height adjustment should be performed before placing the pallet or after unloading materials. When changing to pallets of different specifications, first place the empty pallet on the four support parts 7. According to the height and flatness requirements of the pallet itself, independently adjust the height of each support part 7 by rotating the bolt rod 5 (or nut 6) until the upper surface of the pallet reaches a horizontal state. Then tighten the nut 6 to lock it in place. After adjustment, place materials on the pallet. At this time, the horizontal conveying mechanism 3 can drive the pallet 2, the pallet, and the materials to move along the length of the base frame 1 to the designated position. For pallets that have undergone local deformation due to long-term use, the empty pallet can be adjusted before each loading of materials. The deformation can be compensated by individually adjusting the height of the support part 7 at the corresponding deformation position to ensure that the whole remains horizontal after subsequent loading of materials, which is convenient for the robot to grab or transfer materials.

[0032] In summary, this feeding platform achieves horizontal transport of the pallet 2 and the load through the horizontal conveying mechanism 3. It utilizes multiple sets of independently adjustable height adjustment components 4 to adapt to the height differences of different parts of the load, solving the problems of difficulty in flexibly adapting to various specifications of loads and low adjustment accuracy in the existing technology, and meeting the needs of automated production and logistics transportation for efficient and precise adaptation.
