Description

Technical Field

[0001] This utility model belongs to the field of automation technology, and in particular relates to a pallet loading and unloading device. Background Technology

[0002] Currently, product assembly is completed through assembly lines. These lines divide the production and assembly process into multiple steps, each involving different procedures, thus achieving automation and standardization. At the beginning of the production line, there is an initial feeding station, commonly known as the "line start," and at the end, empty pallets are collected, commonly known as the "line tail." At the line start, products to be processed are placed on pallets. These products are then assembled and processed through various procedures on the assembly line until the finished products are removed, leaving empty pallets at the line tail.

[0003] In existing technologies, empty pallets are placed at the beginning and removed at the end of the line using pallet loading and unloading devices. However, traditional pallet loading and unloading devices require a large working space for the pallet-transferring mechanism to facilitate the transfer of pallets to designated locations. As a result, they occupy a large area and are not suitable for narrow workspaces or compact equipment layouts. These problems urgently need to be solved. Utility Model Content

Therefore, they have no substantial technical significance.

[0026] In order to describe this utility model in detail, the following is a specific description of a pallet loading and unloading device of this utility model:

[0027] Please combine Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a pallet loading and unloading device, including a frame 1, a transport mechanism 3, and a transfer mechanism 2. The transport mechanism 3 is mounted on the frame 1 and includes a first transport track 301 arranged along a first direction. The transfer mechanism 2 includes a lifting and placing component and a mounting base. The lifting and placing component is rotatably mounted on the mounting base, and the mounting base is slidably mounted on the first transport track 301. The lifting and placing component has a lifting and placing surface for picking up and placing pallets, with a first pallet picking position and a second pallet picking position. When the lifting and placing component rotates, the lifting and placing surface reciprocates between the first and second pallet picking positions. By providing a rotatable lifting and placing component, the pallet can be rotated during the pallet transfer process to change the pallet's placement state during picking up and placing. This allows the pallet to be transported in an upright state during the recycling and conveying process, thereby reducing the space occupied by the pallet loading and unloading device. At the same time, by rotating the pallet for transfer, the working space required for pallet transfer during the transfer process can be reduced, making pallet transfer convenient. In this embodiment, the lifting and placing component is rotatably mounted on the mounting base by a rotating motor 213.

[0028] The lifting and placing assembly includes a lifting and placing base 212 and a conveyor mounted on the lifting and placing base 212. The conveyor is positioned on the lifting and placing base 212 corresponding to the picking and placing surface and is used to transport the pallet to or from the picking and placing surface. By setting up the conveyor, the smoothness of pallet transfer to or from the picking and placing surface can be improved, avoiding jamming when the pallet is placed or removed from the picking and placing surface. In this embodiment, the conveyor includes a first annular conveyor belt 207, a first roller 206, and a second roller 208. The first roller 206 and the second roller 208 are arranged sequentially at intervals along a second direction. The first annular conveyor belt 207 is sleeved on the first roller 206 and the second roller 208. The first direction is perpendicular to the second direction. The first roller 206 and the second roller 208 can avoid excessive sliding friction when the pallet is moved on the picking and placing surface, thus preventing wear on the pallet, and at the same time facilitate the movement of the pallet.

[0029] The lifting and placing assembly includes two sets of conveying components, spaced apart along a third direction. The first rollers 206 on both sets share a first drive shaft 205, and the second rollers 208 on both sets share a second drive shaft 209. A driving component is positioned between the two sets of conveying components to rotate the first drive shaft 205 around its axial direction. The third direction is perpendicular to both the first and second directions. This arrangement of two sets of conveying components and the driving component positioned between them allows the two sets to share the same driving component to move the pallet. The structure is simple and provides good transport efficiency. In this embodiment, the driving components are a drive motor 202, a second annular conveyor belt 204, a first transmission gear, and a second transmission gear 203. The drive shaft of the drive motor 202 is connected to the first transmission gear, and the axial direction of the drive shaft is the same as that of the transmission gear. The second transmission gear 203 is mounted on the first transmission shaft 205, and the axial direction of the first transmission shaft 205 is the same as that of the second transmission gear 203. The second annular conveyor belt 204 is mounted on both the first transmission gear and the second transmission gear 203. The second annular conveyor belt 204 has a first transmission tooth on the side of the second annular conveyor belt 204 facing the first transmission gear and the second transmission gear 203. The outer periphery of the first transmission gear and the second transmission gear 203 has a second transmission tooth that meshes with the first transmission tooth on the second annular conveyor belt 204. This prevents the second annular conveyor belt 204 from slipping during transmission.

[0030] The pallet loading and unloading device further includes a first transmission mechanism and a second transmission mechanism. The first transmission mechanism has a first transmission surface for conveying the pallet, which is in contact with the bottom surface of the pallet. The second transmission mechanism has a second transmission surface for conveying the pallet, which is in contact with the side surface of the pallet. The lifting and placing component rotates at an angle of 90 degrees. The first transmission surface and the second transmission surface are parallel. When the lifting and placing surface of the lifting and placing component is located at the first pallet picking and placing position, the picking and placing surface is connected to the first transmission surface, that is, the first transmission surface and the picking and placing surface are coplanar, which facilitates the movement of the pallet between the first transmission surface and the picking and placing surface. When the lifting and placing surface of the lifting and placing component is located at the second pallet picking and placing position, the side surface of the pallet corresponds to the second transmission surface, and the picking and placing surface is perpendicular to the second transmission surface. It should be noted that the pallet has length, width, and height. The length and width of the pallet form the top and bottom surfaces of the pallet. The top surface of the pallet is used to hold the assembled parts, and the bottom surface of the pallet is in contact with the first transmission surface. The length and height or width and height of the pallet form the side surface of the pallet. Either side surface of the pallet is in contact with the second transmission surface. Therefore, during the transmission of the pallet, since the height of the pallet is much smaller than its length and width, the space in the height direction of the setting space can be used efficiently when the pallet is driven by the second transmission mechanism. This reduces the setting area occupied by the pallet loading and unloading device in the setting space. In other words, when the pallet is placed on the second transmission surface for transmission, the area occupied by the projection of the pallet loading and unloading device on the horizontal plane along the direction of gravity can be reduced to a certain extent.

[0031] Specifically, the transfer mechanism 2 is provided with a baffle 201 to block the pallet from moving forward. The lifting base 212 has a connecting edge close to the first transmission mechanism, and the baffle 201 is located on the opposite side of the connecting edge of the lifting base 212. By setting the baffle 201, the position of the pallet can be limited when it is transferred to the transfer mechanism 2, preventing the pallet from partially or completely exceeding the pick-up and put-down surface during the transfer process, which would cause the transfer mechanism 2 to fail to pick up the pallet. In this embodiment, a first sensor is provided on the baffle 201 corresponding to the pick-up and put-down surface. When the pallet is transferred from the first transmission mechanism to the pick-up and put-down surface on the transfer mechanism 2, when the first sensor detects the presence of the pallet, the drive of the conveyor stops working, and at the same time, the baffle 201 prevents the pallet from continuing to move forward in the second direction.

[0032] The lifting and placing assembly includes a lifting and placing base 212 and a suction and placing component for picking up and placing the tray. The suction and placing component is disposed on the lifting and placing base 212 corresponding to the picking and placing surface. Picking up the tray with the suction and placing component avoids scratching the tray. In some embodiments, the lifting and placing assembly includes the lifting and placing base 212 and a clamping component for gripping the tray. When the tray reaches the picking and placing surface, the clamping component clamps the tray on opposite sides. The types of parts used to secure the tray in the lifting and placing assembly can be adjusted according to actual usage needs.

[0033] Specifically, the suction and release mechanism includes suction cups, a vacuum generator for suction and release of air from the suction cups, and a suction cup limiting member 210. The vacuum generator is mounted on the lifting and releasing base 212. The suction and release mechanism includes multiple suction cups and a suction cup placement plate 211. The multiple suction cups are spaced apart on the suction cup placement plate 211. The suction cup placement plate 211 is connected to the lifting and releasing base 212 via the vacuum generator. The suction cup limiting member 210 surrounds the suction cups. By setting the suction cup limiting member 210 around the suction cups, the situation where the suction cups shift during the rotation of the transfer mechanism 2, causing the suction cups to fail to pick up the tray, can be avoided.

[0034] In detail, the transport mechanism 3 further includes a second transport track 302 arranged along a third direction. In this embodiment, the pallet loading and unloading device includes two first transport tracks 301, which are spaced apart on a first transport plate. The two first transport tracks 301 are slidably mounted on the second transport track 302 via the first transport plate. The pallet loading and unloading device also includes two second transport tracks 302, which are spaced apart on the frame 1, with the first direction perpendicular to the third direction. By setting the second transport tracks 302, the transport convenience of the transfer mechanism 2 can be increased, and the adaptability and practicality of the pallet loading and unloading device to different usage environments can be improved. In this embodiment, the first transport track 301 is driven by a transport motor 303 to rotate a lead screw around its axial direction, thereby driving the mounting base to reciprocate along the first direction. The second transport track 302 is also driven by a transport motor 303 to rotate a lead screw around its axial direction, thereby driving the first transport track 301 to move along the second transport track 302 along the third direction.

[0035] In this embodiment, pallet loading and unloading devices are respectively provided at the beginning and end of the above-mentioned production line. At the beginning of the line, the pallet loading and unloading device picks up the bottom surface of the pallet located on the second transmission surface through the suction and release component on the lifting and releasing assembly. The lifting and releasing assembly rotates 90 degrees relative to the mounting base and moves to the first transmission surface through the transport mechanism 3, that is, the connecting edge is close to the first transmission surface and the picking and releasing surface is on the same plane as the first transmission surface. At this time, the suction and release component on the lifting and releasing assembly stops picking up the pallet and transports the pallet to the first transmission surface through the conveyor component on the lifting and releasing assembly. At this time, the bottom surface of the pallet contacts the first transmission surface. The assembly parts are placed on the top surface of the pallet and then conveyed to each production line processing point for the products to be assembled through the first transmission mechanism, and finally reaches the end of the line. At the end of the line, the pallet on the first transmission surface is conveyed to the pick-up and place surface on the lifting and placing assembly via the pallet loading and unloading device. The baffle 201 blocks the pallet from moving forward. After the suction and place component on the lifting and placing assembly picks up the pallet, the lifting and placing assembly rotates 90 degrees relative to the mounting base and moves via the transport mechanism 3 until one side of the pallet corresponds to the second transmission surface. At this time, the pick-up and place surface is perpendicular to the second transmission surface. Then, the suction and place component on the lifting and placing assembly stops picking up the pallet and places the pallet on the second transmission mechanism. The second transmission mechanism then transports the pallet to the beginning of the line, allowing the pallet to be automatically recycled multiple times on the production line, saving labor. Moreover, the pallet loading and unloading device occupies a small amount of transfer and installation space, resulting in good economic benefits.

[0036] In summary, by setting up a rotatable lifting and placing component, the pallet can be rotated during the pallet transfer process, thereby changing the pallet's placement state when picking up and placing the pallet. This allows the pallet to be transported in an upright state during the recycling and conveying process, thus reducing the space occupied by the pallet loading and unloading device. At the same time, by rotating the pallet for transfer, the working space required for pallet transfer can be reduced, making pallet transfer convenient.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
