Description

Technical Field

[0001] This utility model relates to a tray feeding device, belonging to the field of chip processing technology. Background Technology

[0002] In chip manufacturing, pallets serve as the primary carriers or containers. Therefore, during the manufacturing process, pallets are typically used to transport and handle chips and perform related processing actions. In some processing or loading operations, AGVs (Automated Guided Vehicles) are often used to transport the sorted pallets in order to promote the automation of production operations. This requires placing individual pallets that have completed placement or processing actions at the waiting point, and finally having the AGV pick up and transfer the pallets.

[0003] Traditionally, AGV loading is done manually, which results in a lack of automation in the overall production system. The coordination between manual labor and machinery can easily increase the risk of accidents to personnel. Furthermore, due to the high cost of labor, there is an urgent need for an automated method to load AGVs to replace traditional manual labor. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pallet feeding device for automatically feeding pallets to AGV carts. It can automatically feed materials to AGV carts while properly preparing materials, which is convenient to use and can save manpower, thus having good economic benefits.

[0005] To achieve the above objectives, this utility model employs the following technical solution: This utility model provides a pallet loading device, including a mounting frame and a conveying assembly mounted on the mounting frame. A receiving frame with a hollowed-out bottom is mounted on the mounting frame. A lifting assembly is positioned below the receiving frame. The conveying assembly is used to transport the pallet above the lifting assembly. Fixing blocks are mounted on the mounting frame on both sides of the receiving frame. A pad is rotatably mounted on each of the two fixing blocks. Each pad includes a counterweight and a lifting portion. The counterweight is used to press against the mounting frame by gravity. The lifting portion can rotate by contacting a pallet lifted by the lifting assembly. When the counterweight presses against the mounting frame, the lifting portion supports the pallet at the bottom of the receiving frame. A transfer module is also mounted on the mounting frame. A fixing frame is fixedly mounted on the movable end of the transfer module. Two grippers that can move closer or further apart are slidably mounted on both sides of the fixing frame. A first driving device is also mounted on the fixing frame to drive the two grippers closer or further apart.

[0006] Specifically, a feeding frame is provided on one side of the mounting frame, and multiple positioning components are provided on the mounting frame and around the feeding frame. The positioning components include multiple second drive devices and a plug fixedly installed at the movable end of the second drive device. The plug can open the tray to place the tray in the feeding frame onto the conveying component.

[0007] Specifically, a third driving device is also provided at the lower position of the mounting frame. The third driving device is used to drive the top block connected to its movable end to rise and fall. The top block can support and lift the pallet below the material feeding frame.

[0008] Specifically, the conveying assembly includes a conveyor belt assembly fixedly installed below the mounting frame and a guide rail fixedly installed on the mounting frame. A connecting block is slidably installed on the guide rail. The connecting block is connected and fixedly connected to the belt of the conveyor belt assembly. A fourth driving device is also fixedly installed on the connecting block. The fourth driving device is used to drive the clamping assembly connected to its movable end to move up and down. The clamping assembly includes a base plate. A sliding plate is slidably installed on the base plate. A fifth driving device for driving the sliding plate to move horizontally is also fixedly installed on the base plate. A snap-fit ​​plate for snapping onto the bottom of the tray is fixedly installed on both the sliding plate and the base plate.

[0009] Specifically, the conveying assembly is provided in two sets, and the clamping components of both sets of the conveying assembly can be conveyed to the position below the feeding frame by belt conveyor.

[0010] Specifically, the lifting assembly includes a sixth drive device mounted on the mounting frame, which is used to drive the top plate connected to its movable end to rise and fall. The conveying assembly is used to place the pallet above the top plate, and the sixth drive device is used to drive the pallet above the top plate to pass over the pad and convey it into the receiving frame.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention, by setting a receiving frame structure and a pad structure on the mounting frame, allows the pallets being transported to be lifted from the bottom of the receiving frame and stacked inside the receiving frame. The structure has a low lifting range and does not require a vision robot arm, which can reduce costs while achieving efficient pallet transfer, effectively saving human resources and reducing labor costs.

[0013] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0014] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0016] This utility model provides a pallet feeding device for automatically feeding pallets to AGV trolleys. It can automatically feed materials to AGV trolleys while ensuring proper material preparation, facilitating retrieval and saving manpower, thus offering good economic benefits. To achieve the device's structural functions, it includes a mounting frame 1 and a conveying assembly mounted on the mounting frame 1. The conveying assembly is configured to convey pallets. To store pallets for easy transport on the AGV, a receiving frame 2 with a hollowed-out bottom is installed on the mounting frame 1. The specifications of the receiving frame 2 are not limited here but can be referenced. Figure 1 The structure shown employs multiple limiting plates. To allow the pallet to be stored in the receiving frame 2, a lifting assembly is installed below the receiving frame 2. A conveying assembly is then configured to transport the pallet above the lifting assembly, which in turn lifts the pallet into the receiving frame 2. To secure the pallet inside the receiving frame 2, fixing blocks 3 are installed on the mounting frame 1 on both sides of the receiving frame 2. For details, please refer to [reference needed]. Figure 8As shown, pads 4 are rotatably mounted on both fixed blocks 3. Each pad 4 includes a counterweight and a lifting part. The counterweight is used to press against the mounting frame 1 by gravity. The lifting part can rotate the pad 4 by contacting the pallet lifted by the lifting component. When the counterweight of the pad 4 is pressing against the mounting frame 1, the lifting part can support the pallet at the bottom of the receiving frame 2. That is, the pad 4 is in a supporting state under normal conditions. However, the pad 4 can be rotated by the driving action at the bottom to allow the bottom pallet to pass through. After the pallet passes through, the pad 4 can return to its normal supporting function. The pallets are fed from the bottom of the receiving frame 2 one by one until the receiving frame 2 is full. In order to facilitate the transfer of the pallets inside the receiving frame 2 to the AGV, a transfer module 5 is also provided on the mounting frame 1. Its configuration can be referred to Figure 1 As shown, the preferred configuration can be composed of two sets of linear motion modules. A fixed frame 6 is fixedly mounted on the movable end of the transfer module 5, driving the fixed frame 6 to move in a vertical plane. To achieve overall pallet clamping, two gripping plates 8 can be slidably mounted on both sides of the fixed frame 6, moving closer or further apart. The gripping plates 8 extend vertically and are configured to clamp the sides of the pallet (corresponding locking blocks can be configured at the bottom for locking) and constrain the pallet's rotation or offset. Finally, a first driving device 7 is installed on the fixed frame 6 to drive the two gripping plates 8 to move closer or further apart, thus driving the two gripping plates 8 to perform the gripping action. In the above method, the specific form of the conveying components and their feeding method is not limited here, including but not limited to using a robotic arm for transfer; other configurations are sufficient to achieve the structural function.

[0017] This utility model provides a pallet feeding device, specifically a pallet supply placement mechanism, thereby facilitating integrated transfer. Specifically, a feeding frame 9 is provided on one side of the mounting frame 1, which can be designed with reference to the receiving frame 2, capable of limiting the position of the pallet. To allow multiple pallets to be stacked simultaneously on the feeding frame 9, increasing placement efficiency and space utilization, multiple positioning components are provided on the mounting frame 1 and around the feeding frame 9, which can be referred to... Figure 5As shown, the positioning component includes multiple second drive devices 10 and a block 11 fixedly disposed at the movable end of the second drive device 10. The block 11 can open the pallet to place the pallet in the feeding frame 9 on the conveying component. When the blocks 11 are close to each other, they can support the pallet, which facilitates the stacking of pallets on top of them. When supplying pallets to the conveying component, the block 11 can insert the upper pallet to drop the lower pallet separately, thus performing single feeding and avoiding the instability of the conveying process caused by too many pallets being conveyed at the same time. In some preferred embodiments, a transfer station can be configured for material preparation to improve the continuity of operations and avoid waiting. Specifically, a third drive device 12 can be provided below the mounting frame 1. The third drive device 12 is configured to drive the top block 13 connected to its movable end to rise and fall. The top block 13 is configured to support and lift the pallet below the feeding frame 9. During operation, the top block 13 first rises to the bottom of the pallet for support. Then, the second drive device 10 drives the insert blocks 11 to move away from each other to release the pallet. After the top block 13 falls to a certain height, the second drive device 10 drives the insert blocks 11 to align again, thereby separating the bottom pallet from the pallet above it. At this time, the bottom pallet is supported alone on the top block 13, and it is ready to wait for the conveying component to receive the material.

[0018] This utility model provides a pallet loading device, specifically a conveying assembly for moving pallets from the placement frame 9 to the receiving frame 2. Specifically, the conveying assembly includes a conveyor belt assembly 14 fixedly mounted below the mounting frame 1 and a guide rail 15 fixedly mounted on the mounting frame 1. A connecting block 16 is slidably mounted on the guide rail 15, and the connecting block 16 is connected and fixed to the conveyor belt assembly 14. Thus, during belt drive, the connecting block 16 can stably slide along the guiding direction of the guide rail 15. To achieve pallet receiving and placement, a fourth driving device 17 is also fixedly mounted on the connecting block 16. Figure 11As shown, a fourth driving device 17 is configured to drive the clamping assembly connected to its movable end to move up and down. The clamping assembly is configured to clamp the pallet. Specifically, the clamping assembly includes a base plate 18, on which a slide plate 20 is slidably mounted, allowing the slide plate 20 to reciprocate relative to the base plate 18. To achieve the clamping action, a fifth driving device 19 is fixedly mounted on the base plate 18 to drive the slide plate 20 to translate. Simultaneously, snap-fit ​​plates for engaging with the bottom of the pallet are fixedly installed on both the slide plate 20 and the base plate 18. Thus, when the fifth driving device 19 drives the two plates closer or further apart, the snap-fit ​​plates can clamp and support the pallet from below. In the above conveying method, to improve conveying efficiency, it is preferable to configure two sets of conveying components. Both sets of conveying components need to be able to be conveyed by belt to the lower position of the unloading frame 9, so that clamping and transfer can be performed at the clamping position.

[0019] This utility model provides a pallet feeding device, specifically a pallet lifting method. Specifically, the lifting assembly includes a sixth drive device 21 mounted on the mounting frame 1. The sixth drive device 21 is configured to drive the top plate connected to its movable end to lift and lower. At this time, the conveying assembly is used to place the pallet above the top plate, and then the sixth drive device 21 is used to drive the pallet above the top plate to pass the position of the pad block 4 and transport the pallet into the receiving frame 2.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
