Description

Technical Field

[0001] This utility model relates to the field of loading and unloading transfer technology, specifically to a loading and unloading mechanism. Background Technology

[0002] In the field of mechanical manufacturing, after a workpiece completes one processing step, it usually needs to be transferred to the next process or a temporary storage area. This process, namely loading and unloading, is an indispensable part of the production process, and its efficiency and cleanliness directly affect the overall production efficiency and workshop environment.

[0003] Currently, to improve production efficiency, pallets, bins, or specialized tooling are commonly used to centrally hold and transfer multiple workpieces. For example, in the wire EDM process of large-area magnetic blanks (hereinafter referred to as "workpieces") manufactured by powder metallurgy, operators first stack multiple workpieces on a large pallet according to a set quantity, and then use forklifts or other transport equipment to move the entire pallet to the worktable of the wire EDM machine. After the cutting process is completed, the forklift is used again to remove the entire pallet and transport it away.

[0004] However, the aforementioned centralized transfer method has a common and prominent problem: many machining processes, such as cutting, grinding, drilling, and quenching, require the use of coolant, lubricant, or other process fluids. After processing, a large amount of liquid remains on the pallets, baskets, and workpiece surfaces. During transfer, especially when pallets are moved directly by forklifts, this residual liquid drips directly onto the ground, resulting in poor workshop hygiene, failing to meet environmental protection requirements, and increasing additional cleaning costs. Utility Model Content

[0005] The purpose of this invention is to develop a loading and unloading mechanism that can effectively prevent processing stains from dripping directly onto the ground during the loading and unloading process, thus protecting the cleanliness of the workshop environment and meeting environmental protection requirements.

[0006] This utility model is achieved through the following technical solution: providing a loading and unloading mechanism, including a box body, wherein a support plate for supporting a pallet is provided inside the box body, and an opening is provided on one side wall of the box body, wherein the support plate can move back and forth and pass through the opening to move the pallet into the box body or move the pallet out of the box body.

[0007] The loading and unloading mechanism of this utility model has the following advantages compared with the prior art: The loading and unloading mechanism in this application includes an independent box, inside which a support plate for lifting the pallet is placed. The support plate can move back and forth to move the pallet into the box through the opening or to move the pallet out of the box through the opening. This allows wastewater from the process of moving and stacking magnetic materials to be collected in the box instead of dripping directly onto the ground, ensuring a clean workshop floor and meeting environmental protection requirements.

[0008] Furthermore, the box is also equipped with a support frame, on which a liftable support arm is provided, and the bearing plate is located on the support arm and can move back and forth on the support arm.

[0009] The support arm is equipped with a first drive component for driving the support plate to move back and forth.

[0011] Preferably, the support plate is further provided with a first clamping member for clamping the pallet, and the first clamping member is movable back and forth along the support plate.

[0012] The support plate is also provided with a mounting plate for mounting the first clamping member and a third drive assembly for driving the mounting plate to move back and forth.

[0013] Preferably, the first clamping member includes two first clamping blocks arranged opposite each other and a first motor. Each of the two first clamping blocks is provided with a first threaded through hole. The first motor is fixed on the mounting plate, and the output shaft of the first motor is connected to a first lead screw. The first lead screw is screwed into the two first threaded through holes respectively, so as to drive the two first clamping blocks to move closer to each other and further apart.

[0014] In one possible implementation, a shelf is provided inside the box on the left side of the support arm, and the box is also provided with a left-right movable push-pull member for moving a tray on the support plate to the shelf or moving a tray on the shelf to the support plate.

[0015] The support frame can move left and right, and the box is also equipped with a fourth drive component for driving the support frame to move left and right.

[0016] Preferably, the push-pull member includes a sliding plate that can slide left and right on the support arm and a fifth drive assembly for driving the sliding plate to slide, and the sliding plate is provided with a second clamping member for clamping the tray.

[0017] Furthermore, the second clamping member includes two second clamping blocks arranged opposite to each other and a second motor. Each of the two second clamping blocks is provided with a second threaded through hole. The output shaft of the second motor is connected to a second lead screw. The second lead screw is screwed into the two second threaded through holes respectively to drive the two second clamping blocks to move closer to each other and further apart.

[0018] In one possible implementation, a water trough for collecting wastewater is provided below the shelf and / or the support plate, and / or at the bottom of the box.

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. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0024] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] To make the objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments are described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 8 As shown, this embodiment provides a loading and unloading mechanism, including a box 1, a support plate 3 for supporting a pallet 2 is provided inside the box 1, and an opening is provided on one side wall of the box 1. The support plate 3 can move back and forth and pass through the opening to move the pallet 2 into the box 1 or move the pallet 2 out of the box 1.

[0027] In addition, in this embodiment, a support frame 4 is provided inside the housing 1. Specifically, the support frame 4 is set on the bottom plate of the housing 1, and a liftable support arm 5 is provided on the support frame 4. The bearing plate 3 is set on the support arm 5 and can move back and forth on the support arm 5. Preferably, a first drive component 6 for driving the bearing plate 3 to move back and forth is provided on the support arm 5. Under the action of the first drive component 6, the bearing plate 3 can move back and forth to realize loading and unloading. Specifically, during loading, multiple sets of magnetic materials 20 to be processed are first stacked on the tray 2, and the entire tray 2 is placed on the corresponding platform 18. The housing 1 is moved to a position close to the platform 18. The first drive component 6 drives the bearing plate 3 to extend out of the opening and transfer the tray 2 to the bearing plate 3. Then the bearing plate 3 returns to the housing. Inside the housing 1, the pallet 2 is temporarily stored. Then, the housing 1 is moved to the side of the processing equipment 19 for loading, and its height is adjusted. The first drive assembly 6 continues to drive the support plate 3 to extend its opening, transferring the pallet 2 from the support plate 3 onto the processing equipment 19, completing the loading process. Similarly, after the magnetic material 20 is processed, when unloading, the support plate 3 extends first, transferring the pallet 2 along with the magnetic material 20 onto the support plate 3. The support plate 3 then returns to the housing 1, and the magnetic material 20 is unloaded and transferred by moving the housing 1. Compared to the traditional method of directly moving the entire pallet 2 in an open manner using a simple forklift mechanism, this embodiment uses the housing 1 as a protective cover, effectively collecting processing wastewater instead of it dripping directly onto the ground, ensuring a clean workshop floor and meeting environmental protection requirements.

[0028] For more details, please see the appendix. Figure 7 The support frame 4 is also equipped with a second drive assembly 7 for driving the support arm 5 to rise and fall. The height adjustment of the support plate 3 is indirectly driven by the rise and fall of the support arm 5, so that the height can be adjusted accordingly when loading and unloading materials, making it convenient for the pallet 2 to move onto the support plate 3 and to move off the support plate 3.

[0029] For others, see Appendix Figure 4 , 5In this embodiment, the support plate 3 is further provided with a first clamping member 8 for clamping the pallet 2, and the first clamping member 8 can move back and forth along the support plate 3 so that the pallet 2 can be moved more efficiently from the table 18 to the support plate 3 or from the support plate 3 to the processing equipment 19. For example, during loading, the box 1 is moved to one side of the platform 18, with the support plate 3 extending out of the opening. If the height needs to be adjusted, the second drive assembly 7 drives the support arm 5 to rise and fall. After the height is adjusted, the first clamping member 8 moves forward to a position close to the tray 2 and clamps the tray 2. Then, the first clamping member 8 moves backward until the tray 2 is moved onto the support plate 3, and the support plate 3 returns to the box 1. When the box 1 is moved to the loading side of the processing equipment 19, the support plate 3 extends to a position close to the processing equipment 19. After the height is adjusted, the first clamping member 8 drives the tray 2 forward until it is moved to the corresponding position on the processing equipment 19. The first clamping member 8 releases the tray 2 and then returns to the initial position. Finally, the support plate 3 returns to the box 1, and the entire loading process is completed. When the magnetic material 20 is processed and needs to be unloaded and transferred, the principle is similar to that of loading, and will not be described in detail here.

[0030] Furthermore, in this embodiment, the support plate 3 is also provided with a mounting plate 9 for mounting the first clamping member 8 and a third drive assembly 10 for driving the mounting plate 9 to move back and forth. That is, the automatic extension and retraction of the first clamping member 8 can be realized through the third drive assembly 10 and the mounting plate 9, which has a high degree of automation and thus improves work efficiency.

[0031] In this embodiment, preferably, the first clamping member 8 includes two first clamping blocks 801 arranged opposite each other and a first motor 802. Each of the two first clamping blocks 801 has a first threaded through hole 803. The first motor 802 is fixed to the mounting plate 9, and its output shaft is connected to a first lead screw 804. The first lead screw 804 is screwed into the two first threaded through holes 803. The forward and reverse rotation of the first lead screw 804 drives the two first clamping blocks 801 to move closer together and further apart, thus clamping and releasing the tray 2. In this structure, the first clamping member 8 can also be a commercially available clamping mechanism such as a gripper cylinder.

[0032] More specifically, in this embodiment, a shelf 11 is also provided inside the box 1, and the shelf 11 is set on the bottom plate of the box 1 and located on the left side of the support arm 5. Preferably, the shelf 11 has a three-layer structure, and each layer is generally used to place a tray 2, so that multiple trays 2 can be pre-stored in the box 1 to improve loading and unloading efficiency. In actual use, when there are no trays 2 in the first box 1, that is, when there are no trays 2 on the processing equipment 19, three layers of trays 2 can be stored. In the middle of the process, the box 1 that moves back and forth generally only stores trays 2 with magnetic materials 20 on two of the shelves 11, and the other layer is idle for turnover when unloading. For example, when two trays 2 are pre-stored in the box 1 in the middle of the process and move to the side of the processing equipment 19, the processed magnetic materials 20 should be transferred with the trays 2 to the idle shelf 11 in the box 1 first, and then the new magnetic materials 20 to be processed should be transferred to the processing equipment 19, and so on, so as to realize the normal up and down turnover of the trays 2. On the other hand, in the above structure, the housing 1 is also provided with a push-pull component for moving the tray 2 on the support plate 3 to the shelf 11 or moving the tray 2 on the shelf 11 to the support plate 3, and the push-pull component can move left and right within the housing 1. The left and right movement of the push-pull component realizes the automatic switching of the tray 2 between the shelf 11 and the support plate 3, thereby improving work efficiency.

[0033] In this embodiment, more specifically, a sliding base plate 17 is provided on the bottom plate of the housing 1. The sliding base plate 17 is slidably connected to the bottom plate of the housing 1 via a linear slide rail. The support frame 4 is fixed on the sliding base plate 17, and a fourth drive assembly 12 for driving the sliding base plate 17 to move left and right is provided on the bottom plate of the housing 1. The left and right movement of the sliding base plate 17 enables the entire support plate 3 to move left and right within the housing 1, thereby better enabling the tray 2 to move between the support plate 3 and the shelf 11.

[0034] In other embodiments, the support frame 4 can also be connected to the side wall of the housing 1 by a sliding mechanism. For example, corresponding slide rails are respectively set on the front and rear side walls of the housing 1, and the front and rear sides of the support frame 4 are respectively slidably engaged on the front and rear side walls by sliders. The fourth drive component 12 can also be set on one of the front and rear side walls of the housing 1.

[0035] In this embodiment, the push-pull component is mounted on the support arm 5. It includes a sliding plate 13 mounted on the support arm 5 and slidable left and right, and a fifth drive assembly 14 for driving the sliding plate 13 to slide. A second clamping member 15 for clamping the tray 2 is provided on the sliding plate 13. When the tray 2 needs to be moved from the support plate 3 to the shelf 11, the fifth drive assembly 14 drives the sliding plate 13 to move to the left, and the second clamping member 15 is used to abut against the right end of the tray 2 until it is completely transferred to the shelf 11. When the tray 2 needs to be moved from the shelf 11 to the support plate 3, it needs to be clamped and limited on both sides of the tray 2 by the second clamping member 15. The fifth drive assembly 14 drives the sliding plate 13 to move to the right until the tray 2 is transferred from the shelf 11 to the support plate 3. The second clamping member 15 is then released and reset to its initial position.

[0036] Preferably, the second clamping member 15 includes two second clamping blocks 1501 arranged opposite each other and a second motor 1502. Each of the two second clamping blocks 1501 has a second threaded through hole 1503. The output shaft of the second motor 1502 is connected to a second lead screw 1504, which is screwed into the two second threaded through holes 1503. The second motor 1502 drives the second lead screw 1504 to rotate, thereby driving the two second clamping blocks 1501 to move closer together and further apart. Of course, the second clamping member 15 can also be a common clamping structure such as a gripper cylinder.

[0037] In other embodiments, the push-pull component can also be located on the wall of the housing 1, such as the top or side wall of the housing 1; the push-pull component can also be a push-pull plate, a hook, an electromagnet, or other components that can move the tray 2 from the support plate 3 to the shelf 11 and from the shelf 11 to the support plate 3. These are common technical solutions. In this embodiment, a water tank for collecting wastewater is provided below the shelf 11 and / or the support plate 3, and / or at the bottom of the housing 1. Specifically, the water tank is a detachable structure, which is convenient to remove and clean or replace periodically to ensure the cleanliness of the inside of the housing 1.

[0038] In addition, the loading and unloading mechanism of this application also includes an AGV trolley 16 for carrying the box 1. With this configuration, the box 1 does not need to be transferred through other transfer mechanisms and can move freely via the AGV trolley 16. To ensure the stability of the box 1 during movement, a corresponding first positioning part can be provided on the top of the AGV trolley 16, and a mounting base 21 can be provided on the bottom of the box 1, with a second positioning part matching the first positioning part on the mounting base 21.

[0039] Additionally, it should be noted that the drive components involved in this application include the first drive component 6, the second drive component 7, the third drive component 10, the fourth drive component 12, and the fifth drive component 14, etc., which can be driven by meshing gears and racks, or by a nut and screw, or by a transmission chain, and are powered by a motor; each drive component can also be driven by a cylinder or a hydraulic cylinder, these components are common in the market and will not be described in detail in this article.

[0040] It should also be noted that the workpieces stacked in the tray 2 in this application description are not limited to magnetic material 20, but can also be other components to be processed.
