[0001] This utility model relates to the field of material transportation technology, specifically to a material cart positioning mechanism. Background Technology

[0002] In automated workshops, materials are typically transported between workstations using AGVs, which are highly intelligent and automated.

[0003] AGVs typically come equipped with navigation and positioning systems, such as magnetic tape navigation, visual navigation, laser navigation, and QR code navigation, enabling automatic positioning of the AGV within the workstation. However, when using AGVs to transport carts containing parts, the cart's position often deviates after arriving at the designated workstation, leading to inaccurate part positioning. Utility Model Content

[0004] Based on the above description, this utility model provides a material cart positioning mechanism to solve the problem that the position of the material cart often deviates after the AGV transports the material cart to the designated workstation, resulting in inaccurate part positioning.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This application provides a material cart positioning mechanism, including: A horizontal positioning assembly includes two horizontal guide rods, which are parallel to each other and spaced apart in the horizontal direction, forming a positioning channel for the feeding vehicle to pass through between the two guide rods; Two sets of horizontal longitudinal positioning components are distributed at intervals in the horizontal direction, and two guide rods are located between the two sets of horizontal longitudinal positioning components in the horizontal direction perpendicular to the length direction of the guide rod. Each horizontal longitudinal positioning component includes at least two positioning blocks, which are distributed at intervals along the length direction of the guide rod. The positioning blocks can be vertically raised and lowered, and the top of each positioning block is provided with a positioning groove. The bottom surface of the positioning groove is an inclined surface that gradually decreases in height from both ends to the middle in the length direction of the guide rod.

[0006] Preferably, the horizontal longitudinal positioning component includes a lifting drive device for driving at least two of the positioning blocks to move up and down synchronously.

[0007] Preferably, the lifting drive device includes: Base; Mounting bracket, which is mounted on the base and can be vertically raised and lowered relative to the base, and at least two positioning blocks are connected to the mounting bracket; The driving structure includes a driving block, a support member, and a driving member. The driving block is disposed on the base and can move horizontally. The top of the driving block is provided with a support surface. In the direction of movement of the driving block, the height of the support surface gradually decreases from one end to the other. The support member is connected to the mounting bracket and supported on the support surface. The driving member is used to drive the driving block to move or keep it in a set position.

[0008] Preferably, the support member includes a support roller, which is rotatably connected to the mounting frame, and the axis of the support roller is horizontal and perpendicular to the moving direction of the drive block.

[0009] Preferably, a limiting plate is connected to the driving block. The limiting plate is vertically arranged and parallel to the moving direction of the driving block.

In the design, the material cart is equipped with multiple support wheels, the same number as the positioning blocks. When the material cart is transported into the positioning channel by the AGV and reaches the set position, the support wheels correspond one-to-one with the positioning blocks, and the support wheels are positioned above the positioning grooves of the corresponding positioning blocks. As the positioning blocks rise, the support wheels are embedded in the positioning grooves, supported on the bottom surface of the positioning grooves.

It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0021] Reference Figure 1 As shown, this application provides a material cart positioning mechanism, including a horizontal lateral positioning component and two sets of horizontal longitudinal positioning components. The horizontal lateral positioning component is used to position the material cart in a first horizontal direction, and the two sets of horizontal longitudinal positioning components are used to position the material cart in a second horizontal direction. The first direction and the second direction are perpendicular.

[0022] Reference Figure 1 and Figure 2 As shown, the horizontal positioning assembly includes two horizontal guide rods 1, which are parallel to each other and spaced apart in the horizontal direction, forming a positioning channel for the feeding trolley to pass through. The first direction is the horizontal direction perpendicular to the length direction of the guide rod 1, and the second direction is the length direction of the guide rod 1.

[0023] Reference Figure 1 and Figure 2 As shown, specifically, during installation, the guide rods 1 are mounted on the ground at the designed workstation via the support frame 2, and guide ramps 101 are provided at both ends of the two guide rods 1 on the side closest to each other. The guide ramps 101 at the ends of the two guide rods 1 create a flared structure between them at the entrance of the positioning channel, guiding the material cart as it enters the positioning channel to automatically correct its direction. During the process of the material cart entering the positioning channel and reaching the set position, the two guide rods 1 position the material cart horizontally and perpendicular to the length direction of the guide rods 1.

[0024] In this embodiment, the guide rod 1 is a cylindrical rod, and the installation height of the guide rod 1 is designed according to the height of the material car being transported by the AGV vehicle.

[0025] Reference Figure 1 and Figure 3As shown, two sets of horizontal longitudinal positioning components are distributed at intervals in the horizontal direction, and two guide rods 1 are located between the two sets of horizontal longitudinal positioning components in the horizontal direction. The horizontal longitudinal positioning components include at least two positioning blocks 3, which are distributed at intervals along the length direction of the guide rods 1. The positioning blocks 3 can be raised and lowered vertically. The top of the positioning block 3 is provided with a positioning groove 301, and the bottom surface of the positioning groove 301 is an inclined surface whose height gradually decreases from both ends to the middle in the length direction of the guide rods 1.

[0026] In the design, the material cart is equipped with multiple support wheels, the same number as the positioning blocks 3. When the material cart is transported into the positioning channel by the AGV and reaches the set position, the support wheels correspond one-to-one with the positioning blocks 3, and the support wheels are located above the positioning grooves 301 of the corresponding positioning blocks 3. During operation, all support blocks are raised and lowered synchronously. As the positioning blocks 3 rise, the support wheels are embedded in the positioning grooves 301, and the support wheels are supported on the bottom surface of the positioning grooves 301. During the process of the multiple positioning blocks 3 rising and smoothly lifting the material cart, the support wheels move towards the center of the positioning grooves 301 under the guidance of the bottom surface of the positioning grooves 301, until the support wheels move to the center of the positioning grooves 301, thus completing the positioning of the material cart in the length direction of the guide rod 1.

[0027] With the above setup, the horizontal and vertical positioning components work together to automatically and accurately position the material cart in the horizontal plane when it is transported to the designated position in the positioning channel by the AGV. After the material cart is lifted to the set height, it can be positioned in the vertical direction, thus achieving precise positioning of the material cart in three-dimensional space.

[0028] Reference Figure 3 As shown, further, a slot 302 communicating with the positioning groove 301 is opened on the bottom surface of the middle part of the positioning groove 301. The width of the slot 302 is slightly larger than the diameter of the support wheel on the material cart. When the support wheel rolls on the bottom surface of the positioning groove 301 to the middle of the positioning groove 301, it falls into the slot 302. The slot 302 restricts the movement of the support wheel along the length direction of the guide rod 1, that is, restricts the movement of the material cart in this direction. The material cart maintains the designed positioning position during the lifting process.

[0029] Reference Figure 1 and Figure 3 As shown, to achieve the lifting and lowering of the positioning block 3, the horizontal longitudinal positioning assembly also includes a lifting drive device 4, which is used to drive at least two positioning blocks 3 to lift and lower synchronously. In actual operation, the lifting drive devices 4 of the two sets of horizontal longitudinal positioning assemblies operate synchronously, so that all support blocks lift and lower synchronously, thereby smoothly lifting the material cart.

[0030] Reference Figure 1 and Figure 3As shown, the lifting drive device 4 includes a base 41, a mounting frame 42, and a drive structure. The base 41 is supported on the ground. The mounting frame 42 is mounted on the base 41 and can be vertically lifted relative to the base 41. At least two positioning blocks 3 are connected to the mounting frame 42. The drive structure includes a drive block 43, a support member 44, and a drive member 45. The drive block 43 is mounted on the base 41 and can move horizontally. The top of the drive block 43 has a support surface 431. In the direction of movement of the drive block 43, the support surface 431 is an inclined plane whose height gradually decreases from one end to the other. The support member 44 is connected to the mounting frame 42 and supported on the support surface 431. The drive member 45 is used to drive the drive block 43 to move or hold it in a set position.

[0031] Reference Figure 1 and Figure 3 As shown, the positioning block 3 is fixed to the mounting bracket 42 by bolts. In some embodiments, multiple sets of bolt holes can be provided on the mounting bracket 42 along the length of the guide rod 1 to adjust the installation position of the positioning block 3 on the mounting bracket 42 as needed, thereby realizing the adjustable position of the positioning block 3 in the length of the guide rod 1.

[0032] Reference Figure 1 and Figure 3 As shown, specifically, multiple support plates 5 are arranged below the base 41. The support plates 5 are used to fix the base 41 to the ground, and the base 41 is supported on the multiple support plates 5 by support bolts 6. The support bolts 6 have a vertical axis and are threaded onto the base 41. The support frame 2 is installed on two of the support plates 5. With this arrangement, the support base can be leveled by adjusting the support bolts 6, thereby achieving leveling of the positioning blocks 3 and the distribution direction of the positioning blocks 3.

[0033] The base 41 is provided with two support columns 46. The mounting frame 42 is connected to the two support columns 46 through vertical linear guide rails to guide and limit the lifting and lowering of the mounting frame 42.

[0034] Reference Figure 3 and Figure 4 As shown, to improve the stability of the mounting frame 42 at its highest and lowest points, the top of the drive block 43 is provided with supporting horizontal surfaces 432 at both ends of the supporting surface 431 in the direction of movement of the drive block 43. Thus, when the drive block 43 moves to the support member 44 and rests on the supporting horizontal surfaces 432, the drive block 43 is not subjected to horizontal force from the support member 44, improving the support stability of the mounting frame 42 and consequently improving the support stability of the material cart.

[0035] The drive block 43 is mounted on the base 41 via a horizontally arranged linear guide rail. The support member 44 is a support roller, which is rotatably connected to the mounting bracket 42. The axis of the support roller is horizontal and perpendicular to the direction of movement of the drive block 43.

[0036] In this embodiment, the moving direction of the drive block 43 is parallel to the length direction of the guide rod 1. The drive block 43 is formed by slotting the top of a cuboid block, and the bottom surface of the slot forms a support surface 431 and a support horizontal surface 432.

[0037] Reference Figure 3 and Figure 4 As shown, a limiting plate 47 is fixedly connected to the driving block 43. The limiting plate 47 is vertically arranged and parallel to the moving direction of the driving block 43. The limiting plate 47 is provided with a limiting groove 471. The support member 44 is supported on the support surface 431 and passes through the limiting groove 471.

[0038] Reference Figure 1 As shown in this embodiment, each lifting drive device 4 is provided with two sets of drive structures. The two sets of drive structures are arranged at both ends of the mounting frame 42 along the length direction of the guide rod 1. The two sets of drive structures share a single drive component 45 to achieve synchronous operation. Specifically, the drive component 45 is a cylinder. Correspondingly, the cylinder body is fixed on the base 41, the cylinder output shaft is parallel to the axis of the guide rod 1, and the cylinder output shaft is connected to a connecting block. The two drive blocks 43 are fixedly connected by a connecting rod 48 parallel to the guide rod 1, and the connecting block and the connecting rod 48 are fixedly connected.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
