Description

Technical Field

[0001] The present invention relates to the technical field of automatic clustering of PACK battery packs, and in particular to an automatic clustering device and system for detecting the position of PACK battery packs. Background Art

[0002] With the development of new energy and the reduction of lithium battery costs, the application of large-scale energy storage has gradually been accepted by the market; large-scale industrial and commercial energy storage has emerged, and containerized energy storage has been supplied and produced in a large number of projects at home and abroad.

[0003] At present, in the integrated assembly process of containerized energy storage systems, container PACK battery packs are clustered by forklifts and manual labor or by using automatic PACK battery pack clustering equipment. Manual clustering is time-consuming and labor-intensive, while traditional automatic PACK battery pack clustering equipment has problems such as inadequate clustering and easy detachment or falling of PACK battery packs. Traditional clustering equipment usually relies on mechanical limit or preset position for operation, but lacks real-time detection and feedback mechanism, resulting in the inability to confirm whether the PACK battery pack is fully clustered. The problem of inadequate clustering may not be discovered until after the assembly is completed. At this time, the PACK battery pack must be taken out and re-clustered, which greatly reduces the assembly efficiency.

[0004] Moreover, the existing PACK battery pack automatic clustering equipment is mostly used in conjunction with a robotic arm, and most of them clamp the PACK battery pack from both sides, which requires the robotic arm to clamp and release the battery pack multiple times, increasing the risk of the battery pack falling due to not being fully loaded into the battery rack, thereby threatening the safety of the operator and possibly causing damage to the battery pack, reducing the safety of the energy storage battery assembly production process; under this premise, how to use the PACK battery pack automatic clustering equipment that detects whether the PACK battery pack is in place is an urgent technical issue in the industry.

[0010] Preferably, the lifting mechanism further comprises an anti-fall module, the anti-fall module comprises an anti-fall rack and an anti-fall pin, the anti-fall rack is vertically arranged on the lifting frame, and the anti-fall pin abuts against the anti-fall rack when extended.

[0013] Furthermore, the cluster entry mechanism also includes a blocking module, which is arranged at the cluster entry limit position. The blocking module includes a lifting device and a limit device, and the limit device is vertically connected to the lifting device.

[0014] Preferably, the lifting device includes a third driving device, a base plate, at least two guide rods and a second connecting plate, and the limiting device includes a buffer block; the PACK battery pack stops when it hits the buffer block and reaches the cluster limit position; the third driving device is fixed to the base plate, and the at least two guide rods pass through the base plate and are connected to the second connecting plate, and the extension and retraction of the guide rods are controlled by the third driving device.

[0015] Preferably, the cluster entry module further includes a fourth driving device, guide wheels and a conveying roller bar, wherein the guide wheels are arranged on both sides of the PACK battery pack in the forward direction, and the PACK battery pack moves on the conveying roller bar to the cluster entry limit position and abuts against the buffer block.

[0016] Furthermore, the first driving device comprises a rotating cylinder, the rotating cylinder is arranged on the clustering module, the pressure switch is connected to the rotating cylinder, and the rotating cylinder is rotatably connected to the clustering module around an X-axis.

[0019] The present invention provides a method for automatically clustering a PACK battery pack in a third aspect, comprising the following steps:

[0020] S1. Transport the PACK battery pack to the cluster module;

[0021] S2, the limit device at the cluster entry limit position on the cluster entry module rises, the PACK battery pack is moved to the cluster entry limit position, and the movement of the PACK battery pack is limited by the limit device;

[0022] S3, moving the cluster entry module to the position to be clustered;

[0023] S4, the limit device falls, and the pressure switch on the cluster entry module rises, and the PACK battery pack is pushed to the cluster entry position through the pressure switch;

[0024] S5. The thrust on the PACK battery pack is detected by the pressure switch. When the thrust suddenly increases, it proves that the PACK battery pack has reached the cluster entry position, and the pressure switch stops moving.

[0025] Further, in step S4, the pressure switch is driven by a servo motor;

[0026] In step S5, whether the PACK battery pack is in place is determined by the servo motor moving into place and the sudden increase in pressure detected by the pressure switch. After the PACK battery pack is in place, the servo motor stops moving.

[0027] Furthermore, in step S2, the limiting device on the cluster entry module located at the cluster entry limit position is first raised, and then the PACK battery pack is moved to the cluster entry limit position, and the movement of the PACK battery pack is limited by the limiting device;

[0028] In step S4, the limiting device is first dropped, and then the pressure switch on the cluster entry module is raised.

[0029] Compared with the prior art, the beneficial effects that can be achieved by at least one of the above technical solutions adopted in the embodiments of this specification include at least:

[0030] First, the pressure switch of the present invention can be raised and lowered relative to the cluster entry module. When the pressure switch is in the lowered position, it can play a protective role to prevent the PACK battery pack from colliding with the pressure switch during the process of entering the cluster entry module, thereby avoiding surface damage or internal structure damage to the PACK battery pack and improving product quality and reliability. When the PACK battery pack is about to be in place, the pressure switch is raised so that it can contact the PACK battery pack and perform detection to confirm whether the PACK battery pack is correctly clustered and in place, thereby ensuring the effectiveness of the detection and avoiding collision or accidental touch when the PACK battery pack is not in place.

[0031] Second, the blocking module of the present invention can prevent the PACK battery pack from falling off the cluster module, while ensuring that the PACK battery pack is moved to the cluster entry limit position; and the buffer block of the blocking module reduces the physical damage to the PACK battery pack, extends the service life of the battery pack, and ensures the integrity and reliability of the battery pack; when the cluster entry mechanism is moved to the cluster entry position through the lifting mechanism, the blocking module falls down so that the PACK battery pack can enter the cluster correctly.

[0032] Third, the present invention uses a double insurance mechanism to confirm whether the PACK battery pack is in place. The pressure switch can confirm in real time whether the PACK battery pack is in place correctly, avoiding the need to remove the PACK battery pack again because it is not in place, significantly reducing the operation time and speeding up the entire assembly process; the servo motor's in-place judgment as a second confirmation means can further ensure that the battery pack is fully in the cluster. Even if a problem occurs in one of the detection means, the double confirmation mechanism can still ensure that the battery pack is in place correctly, thereby avoiding the need to remove the PACK battery pack again.

[0033] Fourthly, when the lifting platform loses power (such as power outage or gas failure) through the anti-fall module of the present invention, the anti-fall pin can be extended in time and abut against the anti-fall rack to prevent the lifting platform from falling quickly, thereby ensuring the safety of equipment and personnel.

[0048] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0049] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0050] Furthermore, in the description of this specification, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances, and they cannot be understood as limitations on the present invention.

[0051] It should be noted that the X, Y, and Z axes described in the present invention are only the X, Y, and Z axes shown in the accompanying drawings; and the "cluster entry limit position" described in the present application is the position where the PACK battery pack finally reaches after moving on the cluster entry mechanism 2, and the "cluster entry limit position" is the position of the PACK battery pack relative to the cluster entry mechanism 2, not the final position of the PACK battery pack after clustering; the "cluster entry position" described in the present application is the position before the cluster entry mechanism 2 reaches the empty position of the battery cluster that needs to be clustered, and the "cluster entry position" is the position of the cluster entry mechanism 2 relative to the empty position of the battery cluster; the "cluster entry position" described in the present application is the position of the PACK battery pack before the cluster entry mechanism 2 reaches the empty position of the battery cluster that needs to be clustered. The final position of the PACK battery pack after being clustered, the "clustering position" is the position of the PACK battery pack relative to the battery cluster; the clustering mechanism 2 first transports the PACK battery pack to the clustering limit position, and when the lifting platform 11 transports the clustering mechanism 2 to the waiting clustering position, the PACK battery pack is moved from the clustering limit position to the clustering position by the clustering mechanism 2; in this application, the term "forward" refers to the clustering direction of the PACK battery pack, "backward" refers to the opposite direction relative to the clustering direction of the PACK battery pack, "high position" refers to the position where the pressure switch is higher than the height of the conveying roller bar, and "low position" refers to the position where the pressure switch is lower than the height of the conveying roller bar.

[0052] In the prior art, in order to achieve PACK battery pack clustering, manual cooperation with forklifts or automatic PACK battery pack clustering equipment is used. Among them, the automatic PACK battery pack clustering equipment cannot detect whether the PACK battery pack is in place. When the PACK battery pack is not in place, it needs to be taken out again, the clustering efficiency is low, and the PACK battery pack has the risk of falling from a height. Under this premise, how to use practical automated PACK battery pack clustering equipment to detect whether the PACK battery pack is in place, improve clustering efficiency and ensure safety has become an urgent problem to be solved in the industry.

[0053] like Figure 1-Figure 5 The present invention shows a PACK battery pack automatic clustering device that detects the position of the battery pack, including: a lifting mechanism 1 and a clustering mechanism 2. When the PACK battery pack is located in the clustering mechanism 2, the clustering mechanism 2 and the PACK battery pack are moved to the waiting clustering position by the lifting mechanism 1, and then the PACK battery pack is pushed to the clustering position by the clustering mechanism 2; the lifting mechanism 1 includes a lifting platform 11, a lifting guide rail 12 and a lifting frame 13. The lifting guide rail 12 is vertically arranged on the lifting frame 13. The lifting platform 11 is slidably connected with the lifting guide rail 12. The lifting guide rails 12 can be arranged on the four vertical sides of the lifting frame 13 to enhance the stability of the lifting platform 11 The clustering mechanism 2 is connected to the lifting platform 11 in a sliding manner in the Y-axis direction, and the clustering mechanism 2 can move in the Y-axis direction relative to the lifting platform 11; the clustering mechanism 2 includes a clustering module 22, a pressure switch 225 and a first driving device, the pressure switch 225 is connected to the first driving device, the first driving device is movably connected to the clustering module 22, the first driving device drives the pressure switch 225 to rise or fall, the pressure switch 225 is located at a high position when it is raised, and is located at a low position after it is lowered; the pressure switch 225 is raised toward the clustering direction of the PACK battery pack, and the pressure switch 225 pushes the PACK battery pack to the clustering position after it is raised.

[0054] In this solution, a pressure switch 225 is provided in the clustering mechanism 2. The pressure switch 225 abutting against the PACK battery pack is used to determine whether the PACK battery pack has reached the clustering position. When the pressure detected by the pressure switch 225 suddenly increases, it indicates that the PACK battery pack has reached the clustering position, and the PACK battery pack is controlled to stop moving forward. The pressure change can accurately determine whether the PACK battery pack is fully clustered, thereby avoiding incomplete or erroneous clustering caused by inaccurate manual judgment or lack of effective detection means in the automatic clustering device for the PACK battery pack.

[0055] In a preferred embodiment, Figure 1As shown, the lifting mechanism 1 also includes two first limit switches 111 arranged on the lifting platform 11 and a second limit switch 131 arranged on the lifting frame 13. The first limit switch 111 limits the movement of the clustering mechanism 2 in the Y-axis direction, and the second limit switch 131 limits the movement of the lifting platform 11 in the Z-axis direction.

[0056] It should be noted that Figure 1 The number of the first limit switches 111 shown as 2 is only a preference. The two first limit switches 111 limit the distance that the clustering mechanism 2 moves forward and backward on the Y-axis, which not only prevents the clustering mechanism 2 from moving forward too much and colliding with the container, but also prevents the clustering mechanism 2 from detaching from the lifting platform 11 when retreating.

[0057] In a preferred embodiment, Figure 2 and Figure 6 As shown, the lifting mechanism also includes an anti-fall module 14, which includes an anti-fall rack 141 and an anti-fall pin 142. The anti-fall rack 141 is vertically arranged on the lifting frame, and the anti-fall pin 142 abuts against the anti-fall rack 141 when extended; the anti-fall module 1414 also includes a second driving device 143, an anti-fall fixing block 144 and a limiting bolt 145. The second driving device 143 is a cylinder, and the anti-fall fixing block 144 is sleeved on the anti-fall pin 142. The anti-fall pin 142 is provided with a groove, and the limiting bolt 145 passes through the anti-fall fixing block 144 and abuts against the groove of the anti-fall pin 142.

[0058] In the present solution, the anti-fall fixing block 144 is sleeved on the anti-fall pin 142 to provide stable support and guidance, so that the anti-fall pin 142 can maintain a precise trajectory when extending and retracting, avoiding jamming or malfunction due to offset or shaking; by adjusting the position and tightness of the limit bolt 145, the motion range and fixed position of the anti-fall pin 142 can be conveniently adjusted, making the installation and maintenance of the system easier.

[0059] In a preferred embodiment, Figure 7 and Figure 8 As shown, the cluster entry mechanism 2 also includes a blocking module 21, which is arranged at the cluster entry limit position. The blocking module 21 includes a lifting device and a limit device, and the limit device is vertically connected to the lifting device; through the blocking module 21, the PACK battery pack can be moved to the top of the cluster entry module 22 without falling off, and the PACK battery pack is controlled to reach the cluster entry limit position to prepare for cluster entry.

[0060] In a preferred embodiment, Fig.10As shown, the lifting device includes a third driving device 212, a base plate 213, at least two guide rods 214 and a second connecting plate 215, the third driving device 212 is a cylinder, and the limiting device includes a buffer block 211; the PACK battery pack stops when it hits the buffer block 211 and reaches the cluster limit position; the third driving device 212 is fixed to the base plate 213, at least two guide rods 214 pass through the base plate 213 and are connected to the second connecting plate 215, and the extension and retraction of the guide rods 214 are controlled by the third driving device 212.

[0061] In this solution, the third driving device 212 drives the guide rod 214 to extend and retract, thereby realizing automatic control of the limit mechanism, and the extension and retraction of the limit mechanism can be flexibly controlled as needed to prevent the PACK battery pack from colliding with the limit device when it falls into the clustering mechanism 2, and at the same time can control the PACK battery pack to reach the clustering limit position; the second connecting plate 215 ensures the synchronous movement of the two guide rods 214, avoids the problem of unilateral jamming or uneven movement, improves the stability and reliability of the limit mechanism, and ensures the accuracy of each operation; in addition, the buffer block 211 plays a shock-absorbing role when the PACK battery pack contacts, can absorb part of the impact force, reduce the position deviation caused by excessive impact force, and reduce damage to the PACK battery pack and the PACK battery pack automatic clustering device.

[0062] In a preferred embodiment, refer again to Figure 8 The cluster entry module 22 further includes a guide wheel 227 and a conveying roller bar 228 . The guide wheel 227 is arranged on both sides of the PACK battery pack in the forward direction. The PACK battery pack moves on the conveying roller bar 228 to the cluster entry limit position and abuts against the buffer block 211 .

[0063] In this solution, the guide wheels 227 are arranged on both sides of the forward direction of the PACK battery pack to provide a stable guiding effect, prevent the PACK battery pack from deviating during the conveying process, and improve the stability of the conveying; through the cooperation of the conveying roller bar 228 and the buffer block 211, the PACK battery pack can accurately reach the cluster entry limit position.

[0064] In a preferred embodiment, see Fig. 9 The first driving device includes a rotating cylinder 226, which is disposed on the clustering module 22, and the pressure switch 225 is connected to the rotating cylinder 226, which is rotatably connected to the clustering module 22 around the X-axis.

[0065] In this solution, the structure of the rotary cylinder 226 is usually simpler than that of the traditional vertical lifting drive device; since the rotary cylinder 226 realizes the lifting function through a rotating action, the complex linear guide rail and the electric lifting mechanism 1 are eliminated, the overall design is simplified, and the complexity and potential failure points of the equipment are reduced; the rotary cylinder 226 is generally more economical than the vertical lifting device, and the manufacturing and maintenance costs are lower; relative to the vertical lifting device, the rotary cylinder 226 also reduces the number and complexity of components, which not only reduces the initial purchase cost, but also reduces the maintenance cost and equipment downtime; and the rotary cylinder 226 usually has a faster response speed, and can quickly realize the lifting and lowering operation of the pressure switch 225, which is a significant advantage for application scenarios that require high-frequency operation or fast switching; since the rotary cylinder 226 occupies a small space, has a compact structure, and has a more flexible installation position, it can adapt to the assembly requirements of a small space or a complex layout. It can provide more layout possibilities when designing the equipment and increase the degree of freedom of design; in addition, the working mode of the rotary cylinder 226 is usually relatively stable, reducing the vibration and noise that may be generated by vertical movement.

[0066] In a preferred embodiment, refer again to Fig. 9 The clustering module 22 also includes a fourth driving device 221, a slider guide 222, a sliding base 223 and a screw 224; the fourth driving device 221 uses a servo motor, the sliding base 223 is threadedly connected to the screw 224, the rotary cylinder 226 is rotatably connected to the sliding base 223 around the X-axis, and the sliding base 223 is slidably connected to the slider guide 222; the various components of the clustering module 22 are automatically controlled by the fourth driving device 221 and the screw 224, which reduces manual intervention and significantly improves the clustering efficiency.

[0067] like Fig.11 As shown, the present application also includes a PACK battery pack automatic clustering system, including the above-mentioned PACK battery pack automatic clustering equipment, a ground rail mechanism and a PACK battery pack transportation mechanism, the lifting mechanism 1 is slidably connected to the ground rail mechanism, and the PACK battery pack transportation mechanism is connected to the clustering mechanism 2; through the ground rail mechanism, the lifting structure and the clustering mechanism 2 can be flexibly moved in a working space such as a factory building to realize the automatic clustering of multiple battery clusters.

[0068] The use process of the PACK battery pack automatic clustering system in this application is as follows:

[0069] S1, transport the PACK battery pack to the cluster entry mechanism 2 through the transport mechanism;

[0070] S2, the limiting device at the cluster entry limit position on the cluster entry module 22 is raised, the PACK battery pack is moved to the cluster entry limit position through the conveying roller bar 228, and the movement of the PACK battery pack is limited by the limiting device;

[0071] S3, the clustering mechanism 2 slides on the lifting platform 11 along the Y-axis direction to the limit position of the first limit switch 111; S4, the lifting platform 11 drives the clustering mechanism 2 to move to the waiting clustering position;

[0072] S5, the limit device falls, the pressure switch 225 rises, and the pressure switch 225 is moved by the servo motor, and the pressure switch 225 abuts against the PACK battery pack to push it to the cluster entry position;

[0073] S6. The thrust applied to the PACK battery pack is detected by the pressure switch 225. When the thrust suddenly increases, it indicates that the PACK battery pack has reached the cluster entry position, and the pressure switch 225 stops moving.

[0074] In step S6, the pressure increase of the pressure switch 225 and the servo motor reaching the right position jointly determine whether the PACK battery pack has been inserted into the cluster. If the servo motor reaches the right position but the pressure switch 225 does not increase, it means that it is stuck and needs to be removed.

[0075] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the embodiments described later, the description is relatively simple, and the relevant parts can be referred to the partial description of the previous embodiments.

[0076] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
