Description

Technical Field

[0001] The present invention relates to the technical field of battery storage equipment, and particularly relates to a battery interval layered collection and transmission device and a control method thereof. Background Art

[0002] In the field of battery storage, the storage channels of traditional battery storage shelves often have a relatively large depth. In actual operation, if directly relying on an automated manipulator to place battery components into the innermost part of the storage channel, the travel of the manipulator needs to be designed very long, which undoubtedly increases the design difficulty and manufacturing cost of the equipment. Moreover, the manipulator takes a relatively long time to travel back and forth during the access process, and the total time required to place external battery components into the storage channel one by one increases significantly, seriously affecting the efficiency of the access process. In addition, the traditional storage and transmission method is difficult to accurately position and orderly store battery components, and problems such as battery component accumulation and misalignment are likely to occur, which not only reduces the storage density but also may cause damage to the battery components.

[0003] In summary, how to further improve the access efficiency of battery components on the storage shelf, while ensuring the orderly placement of battery components in the storage shelf and avoiding damage to the battery components has become a technical problem to be solved. Summary of the Invention

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0005] The present invention provides a battery interval layered collection and transmission device, including a multi-layered three-dimensional shelf. The shelf is provided with a plurality of storage channels, and an inner girder is fixedly configured at the bottom of each storage channel. A plurality of lower rollers are configured below the inner girder, and a plurality of upper rollers are configured above the inner girder. A power roller is configured inside the storage channel, and a steering roller is configured at the bottom of the outer opening of each storage channel. A transmission belt is configured for the steering roller, upper roller, power roller, and lower roller.

[0006] A plurality of servo motors are configured on the side of the shelf, and each servo motor is drivingly connected to a plurality of power rollers on the same horizontal layer. A plurality of lifting modules are configured above the inner girder, and each group of lifting modules independently drives the upper roller directly above it to lift. The top of the steering roller and the highest point of the travel of the tops of a plurality of upper rollers are on the same horizontal line, and the top of the power roller is lower than the highest point of the travel of the top of the upper roller.

[0007] A support substrate is further provided in the storage channel. The support substrate is provided with a groove, and the upper roller, steering roller, and transmission belt are located in the groove area. Among them, when the travel of the top of the upper roller is at the highest point, the top surface of the transmission belt is higher than the top surface of the support substrate.

[0008] A plurality of sensors for detecting the battery component occlusion signal are configured at the top of the storage channel.

[0009] As a preferred technical solution of the device of the present invention: The lifting module adopts an electromagnetic drive module. The output end of the lifting module faces vertically upward and a base is fixedly installed at the output end. The upper roller is installed on the upper side of the base through a rotating shaft. Among them, the lateral width of the base is smaller than the lateral opening width of the belt groove.

[0010] As a preferred technical solution of the device of the present invention: Each storage channel is also configured with a tensioning roller for maintaining the tension of the conveyor belt.

[0011] As a preferred technical solution of the device of the present invention: A transverse shaft for supporting the lower roller is provided in the storage channel, and a bearing member rotationally and cooperatively connected to the side end of the transverse shaft is configured on the side wall of the storage channel.

[0012] As a preferred technical solution of the device of the present invention: The top surface of the conveyor belt originally supported by the upper roller at the lowest point of the stroke drops below the top surface of the support substrate, and the top end of the power roller is higher than the lowest point of the top end stroke of the upper roller.

[0013] As a preferred technical solution of the device of the present invention: A plurality of side guide rollers for guiding the battery components are configured on both sides inside the storage channel. Among them, the side guide rollers are located above the support substrate.

[0014] As a preferred technical solution of the device of the present invention: The storage channel is also configured with a clutch for driving and connecting the power roller. Among the multiple storage channels on the same horizontal layer, the output end of the servo motor is configured with a linkage shaft drivingly connected to each clutch.

[0015] As a preferred technical solution of the device of the present invention: Let the distance between adjacent sensors be L, and let the width of the battery component be D, then D < 2L.

[0016] The present invention provides a control method for a battery interval layered collection and transmission device, including the following content:

[0017] S1. The forklift transports the battery components on the pallet to the designated area of the shelf, and through the automated manipulator, the battery components are placed one by one at the opening position of the storage channel in the order from bottom to top and from left to right.

[0018] S2. The sensor on the outermost side of the storage channel detects the battery component occlusion signal, the servo motor starts, drives the conveyor belt to rotate, and the conveyor belt drives the battery component to move towards the inside of the storage channel.

[0019] S3. According to the reference direction from the opening to the inside of the storage channel, the sensors are distributed at positions [W1, W2, W3,..., W n to monitor the position of the battery component in real time.

[0020] S4. [W1, W2, W3,..., W n There is a position of Wx-1 , W x , W x+1 Three sensors of W, when the sensor at the W x position detects a battery component occlusion signal, trigger the condition judgment for the conveyor belt to drive the battery component to move and stop:

[0021] S4.1. W x-1 The sensor at the position detects a battery component occlusion signal once until the occlusion signal disappears.

[0022] S4.2. W x The sensor at the position continuously detects a battery component occlusion signal.

[0023] S4.3. W x+1 The sensor at the position does not detect a battery component occlusion signal.

[0024] S5. When the above conditions are met, the conveyor belt stops driving the battery component to move, and the lifting module directly below the position of the battery component drives the upper roller to descend to the lowest point of the stroke.

[0025] S6. Repeat the operations of S2 to S5, and transfer and store battery components into a single storage channel one by one until the single storage channel is full.

[0026] S7. After the storage channel is full, use an automated manipulator to store battery components in other storage channels in the order from bottom to top and from left to right.

[0027] S8. When a battery component needs to be taken out, the automated manipulator operates in the order from top to bottom and from right to left. The upper roller directly below the outermost battery component in the same storage channel rises to the highest point of the stroke to lift the conveyor belt, the servo motor reverses, and the conveyor belt transports the battery component to the opening position outside the storage channel, and is taken out by the automated manipulator.

[0028] Compared with the existing technology, the beneficial effects of the present invention are:

[0029] 1. The present invention does not require a long-stroke manipulator. It only needs to place the battery at the opening of the storage channel, and the conveyor belt automatically transports it inward, shortening the stroke of the manipulator, realizing the replacement of the manipulator's round-trip by automated transportation, and shortening the access time of the battery component; and the sensor monitors the battery position in real time, combines condition judgment to ensure that the batteries are evenly distributed at intervals, fixes the battery position by the lifting of the upper roller, and the conveyor belt starts and stops precisely, avoiding congestion, collision and accumulation of battery components.

[0030] 2. In the present invention, the servo motor is linked with the clutch and can independently drive the conveyor belts of any storage channels; the access process is coordinated by sensors and automated manipulators to reduce manual intervention. Meanwhile, the side guide rollers guide the batteries to move smoothly, the tension rollers keep the conveyor belts stable, and the height difference between the conveyor belts and the support substrates is utilized to control and reduce the frictional impact during transmission and positioning.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not used to limit the present invention.

[0039] Embodiment 1. The present invention designs a battery interval layered collection and transmission device, such as Figure 1 , Figure 2 , Figure 3 , which mainly includes components such as a shelf 1, a transmission system of a storage channel 101, a support substrate 3, a sensor 13 and a side guide roller 12. The specific structural configuration is as follows:

[0040] Such as Figure 1 ,Figure 3 , the multi-layered three-dimensional shelf 1 consists of multi-layered storage channels 101 to form a three-dimensional framework, providing storage stratification in the vertical direction. A single layer of the shelf 1 contains multiple horizontally arranged storage channels 101.

[0041] The stratified design realizes the three-dimensional storage of battery components 11, greatly improving the storage density. The horizontal multi-channel layout facilitates the batch access and storage of the automated manipulator in the order of "from bottom to top, from left to right", reducing the intersection of the manipulator's movement path and improving the operation efficiency.

[0042] The drive system of the storage channel 101:

[0043] As Figure 2 , 3 , 4, the inner girder 2 is fixed to the bottom of the storage channel 101, serving as the support carrier for the upper roller 9 and the lower roller 6. It is made of high-strength metal material to ensure the structural stability. The upper roller 9 is located above the inner girder 2. The upper roller 9 is installed on the base 8 through a rotating shaft and is driven to lift by the lifting module 7. Each group of lifting modules 7 independently controls a group of upper rollers 9.

[0044] The highest point of the top travel of the upper roller 9 is flush with the top of the turning roller 15. At this time, the top surface of the conveyor belt 10 is higher than the top surface of the support substrate 3, and it can lift the battery component 11 and move it along with the conveyor belt 10.

[0045] When it descends to the lowest point of the travel, the top surface of the conveyor belt 10 is lower than the top surface of the support substrate 3, and the battery component 11 falls onto the fixed position on the substrate, realizing the switching between "lifting and transporting" and "positioning and fixing". By controlling the contact state of the conveyor belt 10 and the battery component 11 through lifting, the sliding of the battery component 11 during the transmission process is avoided.

[0046] The lower roller 6 is located below the inner girder 2. The lower roller 6 is installed on the horizontal shaft 4, and the horizontal shaft 4 is rotatably connected to the side wall of the storage channel 101 through the bearing member 5. The lower roller 6 supports the bottom of the conveyor belt 10 and cooperates with the upper roller 9 to form a conveyor belt tensioning path, ensuring the transmission stability.

[0047] As Figure 4 , 5 , 6, the driving roller 14 is located inside the storage channel 101 and is connected to the linkage shaft 19 of the servo motor 16 through the clutch 18. The servo motor 16 drives the driving roller 14 to rotate through the linkage shaft 19 and the clutch 18, driving the conveyor belt 10 to move in a cycle. The clutch 18 can realize the independent start and stop of a single storage channel 101. Multiple channels on the same horizontal layer share the servo motor 16, reducing the number of motors and the cost.

[0048] The turning roller 15 is located at the bottom of the outer opening of the storage channel 101, changing the movement direction of the transmission belt 10 so that the transmission belt forms a closed-loop path of "inner power roller drive + outer turning roller guidance". The transmission belt 10 is wound around the upper roller 9, the lower roller 6, the power roller 14, the turning roller 15 and the tension roller 17 to form a closed transmission loop. The tension roller 17 can automatically adjust the tension of the transmission belt 10 to avoid slack and slippage caused by long-term use, ensuring stable transmission power.

[0049] Such as Figure 2 , 3 , 4, Figure 5 , the support substrate 3 is fixed inside the storage channel 101 and is provided with a belt groove 301. The upper roller 9, the turning roller 15 and the transmission belt 10 are all located in the area of the belt groove 301. The belt groove 301 provides a movement space for the transmission belt 10 to avoid friction with the support substrate 3. When the upper roller 9 descends, the battery component 11 is directly placed on the top surface of the support substrate 3, and the edge of the belt groove 301 forms a limit for the battery component 11 to prevent deviation.

[0050] The height difference between the top surface of the support substrate 3 and the top surface of the transmission belt 11 (controlled by the lifting of the upper roller 9) realizes the switching between the "transmission state" and the "positioning state", reducing the frictional impact during the transmission process and protecting the surface of the battery component 11.

[0051] A plurality of sensors 13 are distributed along the length direction of the storage channel 101 (from the opening to the inside), with a spacing of L, and the width D of the battery component satisfies D < 2L. The sensors 13 monitor the position of the battery component 11 in real time and judge whether the battery component 11 is in place by blocking signals. The sensors 13 replace the traditional mechanical positioning device. The non-contact detection reduces equipment wear. At the same time, through the logical judgment of multiple sensors 13, the positioning accuracy is improved, the spacing between the battery components 11 in the storage channel 101 is ensured to be consistent, and the storage density is increased.

[0052] Such as Figure 1 , 2 , multiple sets of side guide rollers 12 are arranged on both sides of the storage channel 101, located above the support substrate 3 and in contact with the side surface of the battery component 11. The side guide rollers 12 guide the battery component 11 to move smoothly along the center line of the storage channel 101 to prevent the battery component 11 from tipping over or getting stuck due to the skew of the transmission belt.

[0053] Embodiment 2: The present invention designs a control method for a battery storage and layered collection and transmission device, and the main contents are as follows:

[0054] First, after the forklift transports the battery components 11 on the pallet to the designated area of the shelf, the automatic manipulator places the battery components 11 one by one at the opening position of the storage channel 101 in the order from bottom to top and from left to right.

[0055] When the outermost sensor 13 in the storage channel 101 detects a battery unit 11 occlusion signal, the servo motor 16 starts, drives the conveyor belt 10 to rotate, and the conveyor belt 10 drives the battery unit 11 to move towards the inside of the storage channel 101.

[0056] Then, taking the direction from the opening to the inside of the storage channel 101 as the reference direction, assume the position distribution of the sensors 13 in the storage channel 101 is [W1, W2, W3,..., W n , [W1, W2, W3,..., W n where there are three sensors 13 at positions W x-1 , W x , W x+1 .

[0057] When the sensor 13 at the W x position has detected the occlusion signal of the battery unit 11, the condition for the conveyor belt 10 to drive the battery unit 11 to move and stop is:

[0058] (1) The sensor 13 at the W x-1 position detects the occlusion signal of the battery unit 11 once until the occlusion signal of the battery unit 11 detected by the sensor 13 at the Wx - 1 position disappears.

[0059] (2) The sensor 13 at the W x position continuously detects the occlusion signal of the battery unit 11.

[0060] (3) The sensor 13 at the W x+1 position does not detect the occlusion signal of the battery unit 11.

[0061] After the conveyor belt 10 stops driving the battery unit 11 to continue moving, the lifting module 7 directly below the position of the battery unit 11 drives the upper roller 9 down to the lowest point of the stroke.

[0062] According to the above control method, the battery units 11 are transmitted one by one into a single storage channel 101 until the single storage channel 101 is full.

[0063] Then, through the automated manipulator, the battery units 11 are placed into the storage channel 101 in the order from bottom to top and from left to right.

[0064] When it is necessary to take out the battery unit 11, the battery unit 11 is output from the storage channel 101 through the automated manipulator in the order from top to bottom and from right to left.

[0065] When the storage channel 101 outputs the battery unit 11, among all the battery units 11 in the same storage channel 101, the upper roller 9 under the outermost battery unit rises to the highest point of the stroke, pushing up the conveyor belt 10 above it. The servo motor 16 reverses, and the conveyor belt 10 conveys the battery units 11 in the storage channel 101 to the opening position outside the storage channel 101, and the battery units 11 are taken out by an automated manipulator.

[0066] This application solves the pain points of traditional shelves through automated transmission, precise control and compact design, realizes efficient access, orderly storage and safety protection of batteries, and improves the automation level and practicality of battery warehousing.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
