Description

Technical Field

[0001] This invention relates to the field of logistics and transportation technology, specifically to an automated logistics conveying system for Zhongda Mi Battery dry cell batteries. Background Technology

[0002] Medium- and large-capacity sealed batteries, also known as medium- and large-capacity sealed batteries, are one of the mainstream classifications of valve-regulated sealed lead-acid batteries. They are classified by single-cell capacity and specifically refer to medium-capacity, fully sealed, and maintenance-free lead-acid batteries.

[0003] In the existing technology, after the Zhongda Mi battery is assembled and off the production line, it needs to be acid-added. However, the space for acid-adding is limited. If all the batteries are transferred to the acid-adding area for stacking, it may result in a large battery inventory and a large space occupation. This may increase the difficulty of adding acid to the un-acidified batteries and make it difficult to remove and transport the acid-added batteries. Some movement channels may be blocked, affecting transportation efficiency. Summary of the Invention

[0004] The present invention aims to solve the problem that existing medium and large density dry cell batteries are all stacked at the acid filling area during transportation, resulting in a large battery inventory, which may block the transportation channel and affect the transportation efficiency.

[0005] To address the aforementioned issues, this invention provides an automated logistics conveying system for dry cell batteries, including a battery buffer area for storing assembled batteries. The battery acid filling area includes an acid filling system and a battery waiting area. The acid filling system is used to perform acid filling operations on the batteries in the battery waiting area. The battery palletizing area has a palletizing mechanism for performing off-line palletizing operations for assembled batteries; Multiple transfer units, each with a moving device and a carrying structure, the carrying structure having a complete plane for placing multiple medium and large density batteries, the carrying structure being placed on the moving device, the moving device being used to transport multiple medium and large density batteries on the carrying structure between the battery stacking area, the battery acid adding area and the battery buffer area. The logistics control system is used to monitor the number of batteries in the battery buffer area, battery acid filling area, and battery palletizing area.

[0006] The automated logistics conveying system for medium and large-density dry cell batteries provided by this invention has, but is not limited to, the following beneficial effects compared to existing technologies: Adding a battery buffer area between the battery palletizing area and the battery acid filling area can effectively prevent the excess batteries from being ineffectively stacked or occupying the transportation channel when the unloading efficiency in the battery palletizing area is much higher than the loading efficiency in the battery acid filling area, thus ensuring the efficiency of battery transportation.

[0007] As a further aspect of the present invention: the mobile device is an unmanned forklift, which is used to change the height and horizontal position of the load-bearing structure. The mobile device responds to the control commands of the logistics control system and transports medium-density batteries between the battery palletizing area, the battery acid adding area and the battery buffer area.

[0008] As a further aspect of the present invention: the mobile device has one or two front forks, and the load-bearing structure is placed on the corresponding front fork. The load-bearing structure has a first working condition and a second working condition: in the first working condition, the load-bearing structure and the large-density battery above it are synchronously separated from the corresponding front fork; in the second working condition, the load-bearing structure is located on the front fork, and the large-density battery on the load-bearing structure is separated from the load-bearing structure and the front fork separately.

[0009] As a further aspect of the present invention: the mobile device has two front forks, and a spacing adjustment structure is provided between the two front forks to change the spacing between adjacent surfaces of the two front forks. The two front forks and the corresponding load-bearing structure are configured such that: when the spacing between the two front forks is within a first distance, the corresponding load-bearing structure is in a first working condition; when the spacing between the two front forks is greater than the first distance, the corresponding load-bearing structure is in a second working condition, wherein the first distance is greater than or equal to the minimum distance between the two front forks, and less than the maximum distance between the two front forks.

[0010] As a further aspect of the present invention: the bearing structure has a fixed part and a movable part, wherein the movable part is rotatable on the fixed part for forming an inclined surface tilted towards the ground. When the upper surface of the movable part is parallel to the upper surface of the fixed part, the bearing structure is in a first working condition; when the upper surface of the movable part is rotated to form an inclined surface tilted towards the ground, the bearing structure is in a second working condition.

[0011] As a further aspect of the present invention: when the moving part rotates on the fixed part to form an inclined plane tilted towards the ground, the lowest point of the moving part is lower than the plane height of the lowest point of the corresponding fork.

[0012] As a further aspect of the present invention: bases are provided on both sides of the bottom of the fixed part, and the two bases move along the width direction of the fork. A front support structure and a rear drive structure are provided on the base. When the load-bearing structure is in the first working condition, the front support structure is partially located inside the moving part, or partially located directly below the moving part and abutting against the moving part. When the load-bearing structure is in the second working condition, the front support structure is separated from the moving part. The rear drive structure is used to contact the corresponding base through the fork and change the position of the base, so that the load-bearing structure switches between the first working condition and the second working condition.

[0013] As a further aspect of the present invention: the front support structure includes a support plate fixed on the corresponding base, the support plate extending in the direction toward the corresponding moving part; when the bearing structure is in the first working condition, the distance between the two corresponding bases is the minimum, and the support plate abuts against the moving part; when the bearing structure is in the second working condition, the distance between the two corresponding bases is not at the minimum value, and the support plate does not contact the moving part.

[0014] As a further aspect of the present invention: the rear drive structure includes a first rotating shaft fixed on both sides of the moving part, and a second rotating shaft provided on the corresponding fixed part. The first rotating shaft and the corresponding second rotating shaft are provided with bevel gears that mesh with each other. The second rotating shaft is also provided with a spur gear. The base is also provided with a rack that meshes with the corresponding spur gear. The spur gear and the corresponding rack are configured such that when the base moves away from each other, the moving part rotates in a set direction, causing the upper large-density battery to slide down along the inclined plane formed by the rotation of the moving part and separate from the moving part.

[0015] As a further aspect of the present invention: when the distance between the two corresponding bases is at its minimum, the corresponding rack does not mesh with the spur gear, and the minimum moving distance for the rack to mesh with the corresponding spur gear is greater than or equal to the minimum moving distance for the corresponding support plate and the corresponding moving part from a contact state to a non-contact state, and a friction surface is formed between the moving part and the corresponding fixed part.

[0025] like Figure 1 , 8 As shown in Figure 9, the automated logistics conveying system for medium and large density dry cell batteries includes: a battery buffer area 1 for storing assembled batteries; a battery acid filling area 2, having an acid filling system 21 and a battery waiting area 22, wherein the acid filling system 21 is used to perform acid filling operations on the batteries in the battery waiting area 22; a battery palletizing area 3, having a palletizing mechanism for performing off-line palletizing operations on assembled batteries; multiple transfer units 4, having a moving device 41 and a supporting structure 42, the supporting structure 42 having a complete plane for placing multiple medium and large density batteries, the supporting structure 42 being placed on the moving device 41, the moving device 41 being used to transport the multiple medium and large density batteries on the supporting structure 42 between the battery palletizing area 3, the battery acid filling area 2 and the battery buffer area 1; and a logistics control system 5 for monitoring the battery quantity information in the battery buffer area 1, the battery acid filling area 2 and the battery palletizing area 3.

[0026] In this embodiment, the additional battery buffer area 1 has at least two effects. First, batteries removed from the battery stacking area 3 can be temporarily stored in the battery buffer area 1 when the battery acid filling area 2 does not have enough acid filling stations. This prevents medium and large density batteries from piling up near the battery acid filling area 2 due to the much higher unloading efficiency of the battery stacking area 3 compared to the loading efficiency of the battery acid filling area 2, resulting in ineffective storage and potentially blocking passageways. Second, batteries that have already been acidified and removed from the battery acid filling area 2 can also be stored in the battery buffer area 1 for future reference, awaiting the next movement instruction. This also prevents batteries from being lost due to scattered stacking.

[0027] During the transfer process, the mobile device 41 is responsible for moving the batteries from one area to another. It is loaded with a detachable support structure 42, which provides a complete plane so that multiple batteries can be placed on the mobile device 41 at the same time for movement. The cooperation between the mobile device 41 and the support structure 42 can effectively improve the single transport capacity of the mobile device 41 and the overall transportation efficiency.

[0028] The logistics control system 5 facilitates real-time monitoring of battery storage in the battery buffer area 1, battery acid filling area 2, and battery palletizing area 3. It enables timely information transmission and macro-control of battery flow between the three areas. The logistics control system 5 may include a central computer and monitoring probes installed in each area, as well as alarms such as audible and visual alarms. With the monitoring function of the logistics control system 5, information transmission can be made faster, effectively improving the timeliness of transportation.

[0029] In summary, adding a battery buffer area 1 between the battery palletizing area 3 and the battery acid filling area 2 to store excess batteries can effectively prevent the excess batteries from being ineffectively stacked or occupying the transportation channel when the unloading efficiency of the battery palletizing area 3 is much higher than the loading efficiency of the battery acid filling area 2, thus ensuring the transportation efficiency of the batteries.

[0030] like Figure 8 and Figure 9 As shown, optionally, the mobile device 41 is an unmanned forklift used to change the height and horizontal position of the load-bearing structure 42. The mobile device 41 responds to the control commands of the logistics control system 5 to transport medium-density batteries between the battery palletizing area 3, the battery acid filling area 2 and the battery buffer area 1.

[0031] In this embodiment, the unmanned forklift refers to an automated forklift that does not require manual control from a person on the vehicle and can respond to external commands. It has the function of changing the height of the load. For example, a shelf can be set up in the battery buffer area 1, and there are storage compartments of various heights on the shelf. The unmanned forklift, in cooperation with the load-bearing structure 42, can place batteries waiting to be acided or batteries that have been acided on the load-bearing structure 42 into storage compartments of different heights for storage. This can increase the buffer capacity of the battery buffer area 1 for medium and large-density batteries by utilizing the limited land area.

[0032] Implementing the mobile device 41 as an unmanned forklift, enabling it to respond to the control commands of the logistics control system 5, allows the logistics control system 5 to directly issue control commands to the mobile device 41, plan the transportation routes of multiple mobile devices 41, and realize the unmanned and automated control of the entire conveying system, based on knowing the real-time battery quantity in the battery buffer area 1, battery waiting area 22, and battery palletizing area 3. This can effectively save labor costs and improve transportation efficiency.

[0033] like Figure 1-3 As shown, optionally, the mobile device 41 has one or two front forks 411, and the load-bearing structure 42 is placed on the corresponding front fork 411. The load-bearing structure 42 has a first working condition and a second working condition: in the first working condition, the load-bearing structure 42 and the large-density battery above it are synchronously separated from the corresponding front fork 411; in the second working condition, the load-bearing structure 42 is located on the front fork 411, and the large-density battery on the load-bearing structure 42 is separated from the load-bearing structure 42 and the front fork 411 separately.

[0034] In this embodiment, after the mobile device 41 is implemented as an unmanned forklift, it generally has one or two front forks 411. In one possible implementation, a conveyor belt movable in one direction is provided on the load-bearing structure 42. The load-bearing structure 42 has a control source for controlling the conveyor belt and a power source for providing power to the control source. Before transportation, the surface of the load-bearing structure 42 is loaded by an external structure so that the load-bearing structure 42 can carry medium- and large-density batteries. When unloading after transportation, there are two situations. When it is necessary to separate the medium- and large-density batteries from the load-bearing structure 42 at the same time, such as when storing them in the battery buffer area 1 without an automated structure, the mobile device 41 can raise the front fork 411 to the height of the corresponding storage compartment, and then adjust the position of the mobile device 41 so that the front fork 411 extends into the corresponding storage compartment. After confirming that the load-bearing structure 42 is in contact with the bottom of the storage compartment, the front fork 411 is removed so that the medium- and large-density batteries and the load-bearing structure 42 are completely separated from the front fork 411.

[0035] In another scenario, such as when it is necessary to move medium-to-large density batteries to the battery waiting area 22 in the battery acid filling area 2, the battery waiting area 22 may include a conveyor belt for transporting medium-to-large density batteries to the acid filling system 21. In this case, it is necessary to separate the batteries on the carrier structure 42 from the carrier structure 42. A traditional method is to set up a structure such as a robotic arm near the battery waiting area 22 to remove the batteries from the carrier structure 42, so that the carrier structure 42 can be reused without the need for the moving device 41 to wait. However, when the carrier structure 42 can separate the batteries on it from itself, the auxiliary structure such as the robotic arm for gripping can be omitted. That is, when the carrier structure 42 is equipped with an automatically movable conveyor belt, in this case, the moving device 41 can be controlled to align the plane of the carrier structure 42 on the fork 411 with the feed end plane of the conveyor belt for transporting medium-to-large density batteries to the acid filling system 21. Then, the conveyor belt on the corresponding carrier structure 42 can be started, so that the batteries on the carrier structure 42 can be smoothly moved to the other side, realizing the separate separation of the carrier structure 42 from its batteries.

[0036] In summary, the load-bearing structure 42 has a first working condition and a second working condition. Under the first working condition and the second working condition, the load-bearing structure 42 can be applied to different scenarios, making the use of the load-bearing structure 42 more flexible.

[0037] like Figure 1 and Figure 2 As shown, optionally, the mobile device 41 has two front forks 411, and a spacing adjustment structure is provided between the two front forks 411 to change the spacing between adjacent surfaces of the two front forks 411. The two front forks 411 and the corresponding load-bearing structure 42 are configured such that: when the spacing between the two front forks 411 is within a first distance, the corresponding load-bearing structure 42 is in a first working condition; when the spacing between the two front forks 411 is greater than the first distance, the corresponding load-bearing structure 42 is in a second working condition, wherein the first distance is greater than or equal to the minimum distance between the two front forks 411, and less than the maximum distance between the two front forks 411.

[0038] In this embodiment, two front forks 411 are provided on the same mobile device 41. The two front forks 411 can be adjustable forks to facilitate automatic control of the spacing between the two front forks 411. The two front forks 411 are connected to the corresponding load-bearing structure 42 to realize the first working condition and the second working condition of the load-bearing structure 42. In this solution, there is no need to arrange a power source and a power supply for providing power to the load-bearing structure 42, which can greatly reduce the cost and weight of a single load-bearing structure 42, thereby reducing the overall cost of the solution.

[0039] Specifically, by increasing the distance between the two forks 411, the battery on the load-bearing structure 42 can be detached from the load-bearing structure 42 independently; while by decreasing the distance between the two forks 411, the load-bearing structure 42 can be restored to a state where the battery and the load-bearing structure 42 can be separated from the forks 411 synchronously. The power of the load-bearing structure 42 comes from the change in the distance between the two forks 411.

[0040] like Figure 1-4 As shown, optionally, the bearing structure 42 has a fixed part 421 and a movable part 422, wherein the movable part 422 is rotatable on the fixed part 421 for forming an inclined surface inclined towards the ground. When the upper surface of the movable part 422 is parallel to the upper surface of the fixed part 421, the bearing structure 42 is in a first working condition; when the upper surface of the movable part 422 is rotated to form an inclined surface inclined towards the ground, the bearing structure 42 is in a second working condition.

[0041] In this embodiment, the structure of the support structure 42 for independently removing the battery is implemented as an inclined plane tilted towards the ground by the moving part 422. When the moving part 422 is tilted to the ground, the battery on the support structure 42 can slide down under the action of gravity. When the moving part 422 is parallel to the ground, the battery on the support structure 42 cannot slide down under the action of gravity, but is normally stored on the support structure 42. This design can reduce the difficulty of removing the battery from the support structure 42 independently and is applicable to most situations.

[0042] Optionally, when the moving part 422 rotates on the fixed part 421 to form an inclined plane tilted towards the ground, the lowest point of the moving part 422 is lower than the lowest point plane height of the corresponding front fork 411.

[0043] In this embodiment, when the moving part 422 rotates, it has a lowest point of rotation. This lowest point is lower than the lowest point plane of the fork 411. This avoids the problem of the battery falling off when it slides off the support structure 42 due to the height difference between it and the storage plane. This makes the battery more stable and safer when it is separated from the support structure 42.

[0044] like Figure 1-7As shown, optionally, the bottom sides of the fixed part 421 are provided with bases 423, and the two bases 423 move along the width direction of the front fork 411. The bases 423 are provided with a front support structure 424 and a rear drive structure 425. When the load-bearing structure 42 is in the first working condition, the front support structure 424 is partially located inside the moving part 422, or partially located directly below the moving part 422, and abuts against the moving part 422. When the load-bearing structure 42 is in the second working condition, the front support structure 424 is separated from the moving part 422, and the rear drive structure 425 is used to contact the corresponding base 423 through the front fork 411 and change the position of the base 423, so that the load-bearing structure 42 switches between the first working condition and the second working condition.

[0045] In this embodiment, the base 423 can move along the width direction of the fork 411, that is, along the line connecting the same points on the two forks 411. The base 423 can be driven by the fork 411 to adjust its distance. It can be understood that the base 423 can be set in the form of a hollow tube, with the interior of the hollow tube adapted to the width of the fork 411. After the fork 411 is inserted into the hollow tube, the position of the base 423 on the load-bearing structure 42 can be changed by changing the position of the fork 411. Another possible solution is that an elastic structure is provided on one side of the base 423, and the fork 411 is located on one side of the base 423, on the opposite side of the elastic structure in the direction of movement of the fork 411. The fork 411 can push the base 423 closer to the elastic structure, and when the fork 411 moves away from the elastic structure, the base 423 can return to its original position under the action of the elastic force of the elastic structure.

[0046] Understandably, in this design, the battery is only allowed to be placed on the surface of the moving part 422 on the support structure 42, and is not allowed to be placed on the surface of the fixed part 421 or on the part of the moving part 422.

[0047] Understandably, since the moving part 422 is rotatably connected to the fixed part 421, the moving part 422 is essentially supported by only one point. This could potentially cause the other end of the moving part 422 to bend or be pressed down under high load. Therefore, the front support structure 424 is used to provide support for the moving part 422 on the side away from the rotation center of the moving part 422. When the load-bearing structure 42 is in the first working condition, the front support structure 424, by being partially located inside the moving part 422, resists the possibility of one end of the moving part 422 rotating downward, while also sharing part of the load. When the load-bearing structure 42 is in the second working condition, the front support structure 424 is in a state of being disengaged from the moving part 422 to avoid obstructing the rotation of the moving part 422. This ensures the normal functioning of the moving part 422 and also supports the moving part 422 when it needs to bear heavy objects, allowing it to maintain horizontal balance and stability.

[0048] The drive structure 425 is used to transmit power to the moving part 422. The power can come from the change in the distance between the two front forks 411 on the moving device 41. The base 423 is moved by the front forks 411, thereby realizing the rotation function of the moving part 422.

[0049] This solution eliminates the need for a power supply and electric drive structure, thereby reducing the cost of using the load-bearing structure 42.

[0050] like Figure 1-7 As shown, optionally, the front support structure 424 includes a support plate 4241 fixed on the corresponding base 423. The support plate 4241 extends in the direction toward the corresponding moving part 422. When the bearing structure 42 is in the first working condition, the distance between the two corresponding bases 423 is the smallest, and the support plate 4241 abuts against the moving part 422. When the bearing structure 42 is in the second working condition, the distance between the two corresponding bases 423 is not at the minimum value, and the support plate 4241 does not contact the moving part 422.

[0051] In this embodiment, the support plate 4241 establishes a connection between the moving part 422 and the base 423. Since the power in this scheme mainly comes from the base 423 driven by the fork 411, the change of the base 423 also means that the working condition of the load-bearing structure 42 will change. When the support plate 4241 abuts against the moving part 422, the load-bearing structure 42 is in the first working condition. When the load-bearing structure 42 needs to be in the second working condition, the base 423 is pushed and moved by the corresponding fork 411. At the same time, the position of the support plate 4241 also changes, disengaging from the corresponding moving part 422, so that the moving part 422 can rotate in a preset direction to complete the change from the first working condition to the second working condition.

[0052] Understandably, when the load-bearing structure 42 is in the first working condition, the distance between the two corresponding bases 423 is the smallest, and the distance between the forks 411 is also relatively small. When it is necessary to change the working condition of the load-bearing structure 42, the distance between the forks 411 can be increased, thereby continuously increasing the distance between the corresponding bases 423. During this process, as the distance between the bases 423 increases, the rotation angle of the moving part 422 will also continuously increase until it reaches its maximum value. This allows the battery placed on the moving part 422 to slide down under the action of gravity, which facilitates quick unloading while allowing the load-bearing structure 42 to continue to be used on the moving device 41 without the need for the moving device 41 to retrieve a new load-bearing structure 42.

[0053] like Figure 1-7As shown, optionally, the rear drive structure 425 includes a first rotating shaft 4251 fixed on both sides of the moving part 422, and a second rotating shaft 4252 provided on the corresponding fixed part 421. The first rotating shaft 4251 and the corresponding second rotating shaft 4252 are provided with bevel gears 4253 that mesh with each other. The second rotating shaft 4252 is also provided with a spur gear 4254. The base 423 is also provided with a rack 4255 that meshes with the corresponding spur gear 4254. The spur gear 4254 and the corresponding rack 4255 are configured such that when the base 423 moves away from each other, the moving part 422 rotates in a set direction, causing the upper large-density battery to slide down the inclined plane formed by the rotation of the moving part 422 and separate from the moving part 422.

[0054] In this embodiment, the first rotating shaft 4251 provides the rotation center of the moving part 422 on the fixed part 421. Two bevel gears 4253 mesh with each other to change the transmission direction, facilitating adaptation to the actual movement direction of the base 423 and adjusting the transmission ratio. A spur gear 4254, coaxially arranged with one of the bevel gears 4253, is driven by a rack 4255, allowing the second rotating shaft 4252 to rotate according to the actual movement direction of the base 423, thereby driving the first rotating shaft 4251 to rotate and changing the rotation angle of the moving part 422. Through the cooperation of the spur gear 4254 and the corresponding rack 4255, the linear movement of the base 423 can be converted into the rotational movement of the moving part 422, realizing the second working function of the bearing structure 42.

[0055] like Figure 1-7 As shown, optionally, when the distance between the two corresponding bases 423 is the smallest, the corresponding rack 4255 does not mesh with the spur gear 4254, and the minimum moving distance for the rack 4255 to mesh with the corresponding spur gear 4254 is greater than or equal to the minimum moving distance for the corresponding support plate 4241 and the corresponding moving part 422 from the contact state to the non-contact state, and a friction surface 426 is formed between the moving part 422 and the corresponding fixed part 421.

[0056] In this embodiment, when the bearing structure 42 is in the first working condition, the front support structure 424 contacts the moving part 422 and blocks the rotation direction of the moving part 422, making it impossible for the bearing structure 42 to switch from the first working condition to the second working condition. Since both the rack 4255 and the support plate 4241 for abutting the moving part 422 are connected to the corresponding base 423, when the base 423 starts to move, in order to avoid the support plate 4241 blocking the rotation of the moving part 422, the support plate 4241 can be disengaged from the moving part 422. The action of the support plate 4241 precedes the rotation of the moving part 422. The rotation of the moving part 422 is mainly provided by the rotational force generated by the meshing of the corresponding spur gear 4254 and rack 4255. Therefore, during the process of the bearing structure 42 switching from the first working condition to the second working condition, when the base 423 moves in the early stage, the support plate 4241 continuously disengages from the moving part 422, while the corresponding rack 4255 has not yet meshed with the corresponding spur gear 4254 during the movement. This solution can be achieved by adjusting the tooth profile position at the end of the rack 4255. This allows the support plate 4241 to provide stable support for the moving part 422 in the first working condition, and also to disengage before the moving part 422 switches to the second working condition, thus preventing the support plate 4241 from obstructing the rotation of the moving part 422. The friction surface 426 can be provided by a material with a high coefficient of friction, such as silicone, to prevent the possibility of the end of the bearing structure 42 away from the rotation center suddenly losing support and deforming downwards when the support plate 4241 disengages from the moving part 422 and the spur gear 4254 and rack 4255 begin to mesh. The friction surface 426 can be provided on one side of the moving part 422 and the corresponding fixed part 421, or both sides can be provided with materials that can provide the friction surface 426.

Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
