Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to an integrated device for destacking and stacking. Background Technology

[0002] With the development of new energy vehicles, the demand for automotive battery packs is gradually increasing. Battery packs are typically placed in pallets (or cages) during warehousing and transportation, with the pallets stacked to save space. When placing battery packs on pallets, the pallets are first transported to a conveyor line, where they are unpacked manually or by robotic arms. Then, a transfer device places the battery packs onto the pallets, and finally, the pallets are stacked manually or by robotic arms, and a forklift transports the stacked pallets to the storage area. This process involves a heavy workload for workers, and the unpacking and stacking efficiency is low, making it difficult to meet the ever-increasing production demands. Furthermore, robotic arms have the limitation of only being able to handle one type of pallet, making it impossible to unpack or stack pallets of different widths and volumes.

[0003] In view of this, the present invention proposes an integrated device for destacking and stacking to solve or at least alleviate the above problems. Utility Model Content

[0004] The main purpose of this utility model is to propose an integrated destacking and stacking device, which aims to solve the problems of low efficiency of manual operation and poor versatility of robotic arm operation during the destacking and stacking process.

[0005] To achieve the above objectives, this utility model proposes an integrated destacking and stacking device, comprising:

[0006] The conveying mechanism includes a base frame and two conveyor chains, which are installed parallel to each other at intervals on the top of the base frame;

[0007] The outer support includes a vertical frame and a top frame installed on top of the vertical frame. The top frame and the conveyor chain enclose a working space, which includes an inlet and an outlet.

[0008] Definition: The direction from the inlet to the outlet is the forward direction;

[0009] A lifting mechanism includes a lifting assembly and a support plate mounted on the lifting assembly. The support plate is disposed between the two conveyor chains. The lifting assembly is mounted on the base frame and is used to lift the support plate.

[0010] The holding mechanism includes two sets of clamping structures arranged opposite to each other. Each clamping structure includes a telescopic component and a clamping arm. The telescopic component is mounted on the top frame and is used to drive the clamping arm to translate in a direction perpendicular to the forward direction. The two sets of clamping arms move relative to each other.

[0011] In one embodiment, the telescopic assembly includes a telescopic cylinder, a guide rail, and a sliding plate. The guide rail is mounted on the top frame, and the sliding plate is slidably mounted on the guide rail. The telescopic end of the telescopic cylinder is connected to the sliding plate, and the telescopic cylinder is used to drive the sliding plate to slide along the guide rail. The clamping arm is connected to the bottom surface of the sliding plate.

[0012] In one embodiment, the telescopic assembly further includes a buffer mounted on the top frame and disposed on the side of the slide away from the telescopic cylinder.

[0013] In one embodiment, the clamping arm includes a main arm and a support plate. The main arm is connected to the bottom surface of the slide plate, and the support plate is installed at the end of the main arm away from the slide plate. The support plate is used to extend into the side of the material tray to support the material tray.

[0014] In one embodiment, the clamping arm further includes an auxiliary plate, which is mounted on the main arm and spaced apart from the pallet. An accommodating space is formed between the auxiliary plate and the pallet, and a horizontal beam is provided on the side of the tray, with the accommodating space used to accommodate the horizontal beam.

[0015] In one embodiment, the auxiliary plate is detachably connected to the main arm.

[0016] In one embodiment, both the auxiliary plate and the tray have an anti-slip adhesive layer on their opposite sides.

[0017] In one embodiment, the number of holding mechanisms is two sets, and the two sets of holding mechanisms are installed at intervals on the top frame along the forward direction, and the clamping arms located on the same side move synchronously.

[0018] In one embodiment, the destacking and stacking integrated device further includes a workpiece presence detector, which is used to detect the stacking status of the material trays.

[0019] In one embodiment, the destacking and stacking integrated device further includes a blocking component disposed at the outlet. The blocking component includes a mounting platform, a telescopic component, and a driving component. The mounting platform is mounted on the base frame, the driving component is mounted on the mounting platform, and the telescopic component is slidably mounted on the driving component. The driving component is used to drive the telescopic component to extend out of the driving component to block the material tray.

[0020] According to the technical solution provided by this utility model, the integrated destacking and stacking device includes a conveying mechanism, an outer support, a lifting mechanism, and a holding mechanism. The conveying mechanism includes a base frame and two conveyor chains, which are installed parallel and spaced apart on the top of the base frame. The outer support includes a vertical frame and a top frame installed on top of the vertical frame. The top frame and the conveyor chains enclose a working space, which includes an inlet and an outlet. The lifting mechanism includes a lifting component and a support plate installed on the lifting component. The support plate is positioned between the two conveyor chains. The lifting component is installed on the base frame and is used to lift the support plate. The holding mechanism includes two sets of clamping structures arranged opposite each other. Each clamping structure includes a telescopic component and clamping arms. The telescopic component is installed on the top frame. Taking the direction from the inlet to the outlet as the forward direction, the telescopic component drives the clamping arms to translate in a direction perpendicular to the forward direction, and the two sets of clamping arms move relative to each other. With this setup, taking the destacking process as an example, after the stacked pallets enter the workspace via the conveyor, the lifting assembly raises the support plate, allowing it to support the pallet stack. Once the pallet stack rises to a position where the clamping arm can grip it, the telescopic assembly drives the clamping arm to clamp the second-to-last pallet closest to the support plate. The support plate then lowers the pallet placed on it, allowing it to be transported by the conveyor chain from the exit to the outside of the workspace. The support plate then rises again, allowing the pallet stack to rest on it. The support plate lowers the pallet stack to a certain height, allowing the clamping arm to clamp the second-to-last pallet closest to the support plate again. The support plate then lowers the pallet placed on top of it, allowing it to be removed from the workspace. This process is repeated until the pallet stack is completely destacking. The stacking process is the reverse of the destacking process. In this way, the use of manual labor or robotic arms for destacking and stacking operations can be avoided. At the same time, the movement distance of the telescopic component driving the clamping arm can be adjusted according to production needs, thereby adjusting the distance between the two clamping arms so that the holding mechanism can clamp pallets of different widths and volumes. Thus, the destacking and stacking integrated device can meet the destacking and stacking process of different types of pallets. Attached Figure Description

[0041] New energy vehicles, with their environmental and energy-saving advantages, have become a new trend in the automotive industry. As the new energy vehicle market continues to expand, the demand for battery packs, one of their core components, is also gradually increasing. During the storage and transportation of battery packs, to avoid damage, they are usually placed in pallets (or cages). These pallets are typically stacked, reducing storage space utilization. When placing the battery packs into pallets, both the battery packs and pallets need to be transported to the production line. Since the pallets are stacked, they need to be destacking first. Destacking is generally done manually or by robotic arms. After destacking, the pallets are arranged separately on the production line, and the transfer equipment then places the battery packs into the pallets for stacking. The stacking operation is the reverse of the destacking operation and still requires manual or robotic arms. After stacking, a forklift transports the pallets to the storage area, awaiting subsequent transportation or requisition.

[0042] The applicant found that while manual operation during destacking and stacking facilitates cost control, it results in a heavy workload for workers. Prolonged, high-intensity work not only easily leads to worker fatigue and reduced efficiency but also increases the probability of workplace accidents. Furthermore, manual operation is relatively inefficient and cannot meet the ever-increasing demand for battery packs. With the continuous increase in production targets and the accelerated pace of production, the speed of manual operation has become a bottleneck restricting the entire production process. If robotic arms are used for destacking and stacking, firstly, the robotic arms require a separate working area on the side of the production line, which is not conducive to reducing the production line's floor space; secondly, one type of robotic arm can typically only handle one type of pallet. In actual production, different vehicle models and battery pack specifications have different requirements for pallets, and the width and volume of the pallets also vary. This means that robotic arms cannot destacking or stacking pallets of different widths and volumes, greatly limiting their flexibility and versatility.

[0043] Therefore, this utility model proposes an integrated device for destacking and stacking to solve the above problems.

[0044] Please see Figures 1 to 3 In one embodiment of this utility model, the integrated destacking and stacking device 100 includes a conveying mechanism 1, an outer support 2, a lifting mechanism 4, and a holding mechanism 5. The conveying mechanism 1 includes a base frame 11 and two conveyor chains 12, which are installed parallel to each other on the top of the base frame 11. The outer support 2 includes a vertical frame 21 and a top frame 22 installed on the top of the vertical frame 21. The top frame 22 and the conveyor chains 12 enclose a working space 3, which includes an inlet 31 and an outlet 32. The lifting mechanism 4 includes a lifting component 42 and a support plate 41 installed on the lifting component 42. The support plate 41 is disposed between the two conveyor chains 12. The lifting component 42 is installed on the base frame 11 and is used to lift the support plate 41. The holding mechanism 5 includes two sets of clamping structures arranged opposite each other. Each clamping structure includes a telescopic component 51 and a clamping arm 52. The telescopic component 51 is installed on the top frame 22. The direction from the inlet 31 to the outlet 32 ​​is denoted as the forward direction X (see reference). Figure 1 (In the direction indicated by the middle arrow X), the telescopic component 51 is used to drive the clamping arm 52 to translate in a direction perpendicular to the forward direction X, and the two sets of clamping arms 52 move relative to each other.

[0045] Within the same horizontal plane, the direction perpendicular to the forward direction X is the translation direction Y (see [reference]). Figure 1 (The direction indicated by the middle arrow Y). The clamping arm 52 can reciprocate along the translational direction Y under the action of the telescopic assembly 51, thereby enabling the two sets of clamping arms 52 to move relative to each other to clamp or release the tray 200. The lifting assembly 42 is used for vertical movement in the Z direction (see...). Figure 1The lifting assembly 41 (pointed to by the middle arrow Z) is used to lift the support plate 41. The gap between the two conveyor chains 12 is used for the passage of the support plate 41. The lifting assembly 42 includes one of a scissor lift, a two-post lift, and a combined lift. In this embodiment, the lifting assembly 42 adopts a scissor lift, which has the advantages of occupying little space when the scissor arm structure is not extended, having a wide range of applications, and high lifting accuracy. When the scissor lift is in the non-extended state, the height of the support plate 41 is lower than the top surface height of the conveyor chain 12 to avoid affecting the conveying of the material tray 200.

[0046] Taking the destacking process as an example, the stacked material trays enter the working space 3 under the conveying of the material. The lifting component 42 lifts the support plate 41, so that the support plate 41 supports the material trays. After the material trays rise to the range that the clamping arm 52 can clamp, the telescopic component 51 drives the clamping arm 52 to clamp the second to last material tray 200 near the support plate 41 (that is, the second material tray 200 from bottom to top along the vertical direction Z). Then the support plate 41 drives the material tray 200 placed on the support plate 41 to descend, so that the material tray 200 can be transported by the conveyor chain 12 from the outlet 32 ​​to the outside of the working space 3. The support plate 41 then rises again, allowing the pallet stack to be placed on it. The support plate 41 lowers the pallet stack to a certain height, allowing the clamping arm 52 to clamp the second pallet 200 from the bottom in the vertical Z direction. The support plate 41 then lowers the pallet 200 placed on it, allowing it to be transported out of the workspace 3. This process is repeated until the pallet stack is completely disassembled. The stacking process is the reverse of the destacking process.

[0047] With the configuration of this embodiment, the use of manual or robotic arms for destacking and stacking operations can be avoided. At the same time, the movement distance of the telescopic component 51 driving the clamping arm 52 can be adjusted according to production needs, thereby adjusting the distance between the two clamping arms 52 so that the holding mechanism 5 can clamp material trays 200 of different widths and volumes. Thus, the destacking and stacking integrated device 100 can meet the destacking and stacking process of different types of material trays 200.

[0048] There are various implementations of the telescopic component 51. In one embodiment of this utility model, please refer to... Figure 4The telescopic assembly 51 includes a telescopic cylinder 511, a guide rail 512, and a sliding plate 513. The guide rail 512 is mounted on the top frame 22, and the sliding plate 513 is slidably mounted on the guide rail 512. The telescopic end of the telescopic cylinder 511 is connected to the sliding plate 513, and the telescopic cylinder 511 is used to drive the sliding plate 513 to slide along the guide rail 512. The clamping arm 52 is connected to the bottom surface of the sliding plate 513. The telescopic cylinder 511 includes either a pneumatic cylinder or an electric cylinder. The sliding plate 513 is connected to the movable rod of the telescopic cylinder 511, and the sliding plate 513 can reciprocate on the guide rail by extending and retracting the movable rod within the cylinder. In the two sets of opposing clamping structures, the sliding plate 513 slides relative to each other, thereby driving the two clamping arms 52 to move relative to each other. The telescopic assembly 51 provided in this embodiment has the advantage of simple structure.

[0049] In another embodiment, the telescopic assembly 51 includes a lead screw motor, a guide rail 512, and a sliding plate 513. The lead screw motor is mounted on the top frame 22, and the sliding plate 513 is threadedly engaged with the lead screw. As the lead screw rotates, the sliding plate 513 can reciprocate on the guide rail 512. The telescopic assembly 51 provided in this embodiment has the advantages of high precision and easy operation.

[0050] Furthermore, in one embodiment of this utility model, please refer to... Figure 4 The telescopic assembly 51 also includes a buffer 514, which is mounted on the top frame 22 and positioned on the side of the slide plate 513 away from the telescopic cylinder 511. The buffer 514 provides limiting and cushioning for the slide plate 513. In this embodiment, the buffer 514 is one of a hydraulic, spring, or gas type. By providing the buffer 514, excessive translation of the slide plate 513 and clamping arm 52 is prevented, thus avoiding collision with the top frame 22. This accelerates the mechanical cycle of the slide plate 513, shortens its deceleration time, and consequently reduces the cycle time for destacking and stacking.

[0051] In one embodiment of this utility model, please refer to Figure 2 The clamping arm 52 includes a main arm 521 and a support plate 522. The main arm 521 is connected to the bottom surface of the slide plate 513. The support plate 522 is installed at the end of the main arm 521 away from the slide plate 513. The support plate 522 is used to extend into the side of the tray 200 to support the tray 200. To improve the connection strength between the support plate 522 and the main arm 521, the support plate 522 and the main arm 521 are welded together. The support plate 522 allows the tray 200 to be stably mounted on the clamping arm 52, thus eliminating the need for the main arm 521 to clamp the tray 200. This reduces the driving force required by the telescopic assembly 51 to provide to the clamping arm 52, making it easier to select a small driving component in the telescopic assembly 51 and reducing the cost of the telescopic assembly 51. In addition, using the support plate 522 to support the tray 200 also improves the stability of the tray 200 after it is detached from the support plate 41.

[0052] In one embodiment of this utility model, the clamping arm 52 further includes an auxiliary plate 523, which is installed on the main arm 521 and spaced apart from the support plate 522. A receiving space is formed between the auxiliary plate 523 and the support plate 522. A horizontal beam is provided on the side of the material tray 200, and the receiving space is used to receive the horizontal beam. The receiving space is trough-shaped, with its opening facing the horizontal beam of the material tray 200. This arrangement can effectively prevent the material tray 200 from slipping due to vibration or tilting when it is lifted, thereby avoiding damage to the material tray 200 and production line shutdown.

[0053] Furthermore, in one embodiment of this utility model, the auxiliary plate 523 is detachably connected to the main arm 521. Specifically, it adopts one of bolt connection and pin connection. The detachable design allows for the replacement of auxiliary plates 523 of different specifications (such as width and shape adjustment) according to task requirements, and supports adjustment of the distance between the auxiliary plate 523 and the support plate 522 to accommodate different sized trays 200.

[0054] In one embodiment of this utility model, the main arm 521 includes an outer arm and an inner arm. The outer arm is sleeved on the inner arm and connected to the bottom surface of the slide plate 513. The support plate 522 and the auxiliary plate 523 are both installed on the inner arm. Both the outer arm and the inner arm are provided with through holes that can cooperate with each other. The outer arm has multiple through holes, which are spaced apart along the vertical direction Z. The through holes of the outer arm and the through holes of the inner arm are connected by pins. This arrangement allows the length of the main arm 521 to be adjusted, thereby adapting to the stacking and unstacking operations of pallets 200 with different layers and heights.

[0055] In one embodiment of this utility model, an anti-slip adhesive layer is provided on the facing sides of the auxiliary plate 523 and the tray 522. The anti-slip adhesive layer increases the friction between the tray 522 and the tray 200, and between the auxiliary plate 523 and the tray 200, thereby preventing the tray 200 from shifting. Furthermore, the anti-slip adhesive layer protects the tray 200, the tray 522, and the auxiliary plate 523, preventing direct friction between the tray 200 and the other two, and reducing scratches or coating peeling.

[0056] In one embodiment of this utility model, please refer to Figure 1 The number of retaining mechanisms 5 is two sets, which are installed at intervals along the forward direction X on the top frame 22, and the clamping arms 52 on the same side move synchronously. By setting two sets of retaining mechanisms 5, two sets of opposing clamping structures are installed in the top frame 22, which makes the force on the material tray 200 more balanced when lifting or clamping it, thereby further ensuring the stability of the material tray 200 and reducing the possibility of the material tray 200 tipping over or falling.

[0057] In one embodiment of this utility model, the destacking and stacking integrated device 100 further includes a workpiece presence detector, which is used to detect the stacking state of the pallets 200. Specifically, the workpiece presence detector includes one of an infrared sensor and a laser sensor, used to identify the stacking state of the pallets 200 and send the state information to a control center (computer, PLC, etc.). The control center controls the movement state of the lifting assembly 42, the telescopic assembly 51, and the conveyor chain 12 based on the state information, thereby improving the automation level of the destacking and stacking process. In this embodiment, the stacking state of the pallets 200 includes a stacked state and a non-stacked state. For example, the stacking state can be specifically represented by the height information of the pallet stack. When the pallets 200 are in a stacked state, the height of the pallet stack is relatively high. At this time, the infrared rays or laser emitted by the workpiece presence detector are blocked by the pallets 200, so the workpiece presence detector can determine that the pallets 200 are in a stacked state. If the pallets 200 cannot block the infrared rays or laser emitted by the workpiece presence detector, it can be determined that the pallets 200 are in a non-stacked state. Taking the destacking process as an example, after the material tray 200 enters the working space 3, if the material tray 200 is in a stacked state, the conveyor chain 12 is turned off and the telescopic component 51 and the lifting component 42 are turned on to carry out the destacking operation; if the material tray 200 is in a non-stacked state when it enters the working space 3, there is no need to carry out the destacking operation, and the conveyor chain 12 directly transports the material tray 200 to the outside of the working space 3.

[0058] In one embodiment of this utility model, please refer to Figure 5 The destacking and stacking integrated device 100 also includes a blocking component 6, which is located at the outlet 32. The blocking component includes a mounting platform 61, a telescopic component 62, and a driving component. The mounting platform 61 is mounted on the base frame 11, the driving component is mounted on the mounting platform 61, and the telescopic component 62 is slidably mounted on the driving component. The driving component is used to drive the telescopic component 62 to extend out of the driving component to block the material tray 200. Specifically, the telescopic component 62 includes a telescopic rod 621 and a limiting head 622. The limiting head 622 is provided with rollers, and the telescopic rod 621 can extend and retract within the driving component. In this embodiment, the telescopic rod 621 and the driving component can be either a pneumatic cylinder or an electric cylinder. The limiting head 622 is used to prevent the material tray 200 from sliding out of the working space 3. During the destacking and stacking operation, the limiting head 622 rises vertically in the Z direction along the telescopic rod 621, thereby blocking the material tray 200. The roller in the limiting head 622 is used to directly contact the material tray 200. The roller can be made of rubber, PC material or other materials with a certain degree of elasticity to prevent the limiting head 622 from scratching the material tray 200 while blocking the sliding of the material tray 200.
