Technical Field

[0001] The utility model relates to the technical field of trays, and more specifically, to a battery pack drum tray. In addition, the utility model also relates to a battery pack cluster rack placement system including the above battery pack drum tray. Background Art

[0002] With the rapid development of the new energy industry, battery packs are widely used in the fields of new energy vehicles, energy storage, mobile electronic products, power tools, etc. After the energy storage battery pack is produced, it needs to be placed and installed on the cluster rack, and the cluster rack is moved into the container by a forklift to complete the container integration for convenient transportation of the battery pack.

[0003] However, in the current process of placing the battery pack on the cluster rack, it is necessary to cooperate with a forklift. First, the forklift is used to lift the battery pack and the tray to a position flush with the installation surface of the cluster rack, and then the battery pack is manually pushed into the cluster rack. This method is not only laborious and inefficient due to manually pushing the battery pack into the cluster rack, but also increases the manual labor intensity and cost. Moreover, since the height of the cluster rack is often relatively high, the difficulty of manually pushing the battery pack into the cluster rack is increased.

[0004] In summary, how to provide a device for conveniently and quickly placing the battery pack on the cluster rack and reducing the difficulty of placing the battery pack is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a battery pack drum tray, which is convenient for workers to place it inside the cluster rack.

[0006] Another purpose of the utility model is to provide a battery pack cluster rack placement system including the above battery pack drum tray, which realizes the automatic placement of the battery pack and improves the automation of production.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A battery pack roller tray includes a bracket, a centering component, and an end pushing component. A number of rollers are rotatably installed on the bracket, arranged in parallel and used to push the battery pack. The rollers are driven by a chain. A motor for driving the rollers to rotate is installed on the bracket. That is, when the battery pack is on the rollers, the rotation of the rollers can drive the battery pack to move. The centering component includes two side plates and a centering driving member, which are used to position the battery pack and are respectively located at both ends of the rollers. The centering driving member is used to drive the two side plates to approach or move away from each other. Driving the two side plates to approach by the centering driving member is beneficial to place the battery pack in the middle position of the bracket. The end pushing component is installed at one end of the bracket where the battery pack is separated. After the rollers push the battery pack and separate from the battery pack, the end pushing component is used to push the battery pack out of the bracket, which is beneficial to the end conveying of the battery pack and avoids the situation where the battery pack cannot completely separate from the bracket.

[0009] Furthermore, the present utility model further includes a limiting mechanism, which is used to limit the movement of the battery pack in the direction perpendicular to the rollers.

[0010] Furthermore, the limiting mechanism of the present utility model includes:

[0011] A baffle, installed at one end of the bracket away from the end pushing component;

[0012] A limiting air cylinder, with a stop block installed on the limiting air cylinder;

[0013] When the battery pack is on the bracket, the limiting air cylinder extends to limit the battery pack.

[0014] Furthermore, the centering component of the present utility model further includes:

[0015] A number of slide rails, arranged parallel to the axis of the rollers, and the two side plates are slidably matched with the slide rails.

[0016] Furthermore, the end pushing component of the present utility model includes:

[0017] A pushing member, which is used to push the battery pack to move in the direction perpendicular to the axis of the rollers and separate from the bracket.

[0018] Furthermore, the end pushing component of the present utility model further includes:

[0019] A push block;

[0020] A tightening member, which is used to drive the push block to move along the direction of the rollers, and the pushing member can push the tightening member to move.

[0021] When the battery pack is at the end of the bracket, the tightening member drives the push block to move towards the battery pack side.

[0022] Further, for the present utility model, the centering driving member, the pushing member and the pressing member are cylinders, and the corresponding pushing function is realized through the telescopic movement of the cylinders;

[0023] Alternatively, an electric cylinder is used, and the corresponding pushing function is realized through the telescopic movement of the electric cylinder;

[0024] Alternatively, a motor screw mechanism is used, and the corresponding pushing function is realized through the rotation of the screw driven by the motor.

[0025] Further, for the present utility model, a top plate located below the roller is installed on the bracket.

[0026] For the battery pack roller tray provided by the present utility model, during use, a plurality of rollers arranged in parallel and used for pushing the battery pack are installed on the bracket, and the rollers are driven by a chain. A motor for driving the rollers to rotate is installed on the bracket. When the battery pack is located on the rollers, the rotation of the rollers can drive the battery pack to move. That is to say, when it is necessary to move the battery pack to the cluster rack, it can be automatically pushed, avoiding the need for manual pushing by workers, reducing the labor intensity and cost of workers. The centering component includes two side plates and a centering driving member, which are used to position the battery pack and are respectively located at both ends of the roller. The centering driving member is used to drive the two side plates to approach or move away from each other. Driving the two side plates to approach by the centering driving member is beneficial to place the battery pack in the middle position of the bracket, avoiding the situation where the battery pack cannot correctly enter the cluster rack due to the battery pack being skewed or having a large deviation, and effectively avoiding damage to the battery pack during movement. The end pushing component is installed at one end of the bracket where the battery pack is separated. After the roller pushes the battery pack and the battery pack is separated from the roller, the end pushing component is used to push the battery pack out of the bracket, avoiding the situation where the tail end of the battery pack leaks out of the cluster rack, which is beneficial to improving the neatness of the battery pack placement.

[0027] The battery pack cluster rack placement system provided by the present utility model includes the above-mentioned battery pack roller tray, and has the effect of realizing the automation of battery pack cluster rack placement. Description of the Drawings

[0036] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0037] The core of the present utility model is to provide a battery pack roller tray, which is convenient for workers to place it inside the cluster rack 1. Another core of the present utility model is to provide a battery pack cluster rack placement system including the above battery pack roller tray, which realizes the automatic placement of the battery pack 3 and improves the automation of production.

[0038] Please refer to Figures 1 - 5A battery pack roller tray includes a bracket 4, a centering component 5 and an end pushing component 6. A plurality of rollers 7 arranged in parallel and used for pushing the battery pack 3 are rotatably mounted on the bracket 4, and the rollers 7 are driven by chains. A motor for driving the rollers 7 to rotate is mounted on the bracket 4. That is, when the battery pack 3 is located on the rollers 7, the rotation of the rollers 7 can drive the battery pack 3 to move. The centering component 5 includes two side plates 502 and a centering driving member 501, which are used to position the battery pack 3 and are respectively located at both ends of the roller 7. The center driving member 501 is used to drive the two side plates 502 to move closer to or away from each other. The center driving member 501 drives the two side plates 502 to move closer to each other, which is conducive to placing the battery pack 3 in the middle position of the bracket 4. The end pushing component 6 is installed at the end where the bracket 4 is separated from the battery pack 3. When the roller 7 pushes the battery pack 3 and is separated from the battery pack 3, the end pushing component 6 is used to push the battery pack 3 out of the bracket 4, which is conducive to the end-to-end transportation of the battery pack 3 and avoids the situation where the battery pack 3 cannot be completely separated from the bracket 4.

[0039] It should be noted that the embodiment of the utility model does not limit the specific structure of the centering drive member 501. In some embodiments, the centering drive member 501 can be a cylinder, an electric cylinder or a hydraulic cylinder, or a motor, such as a DC brushed motor or a stepper motor.

[0040] In addition, the embodiment of the utility model does not limit the specific structure of driving the rotation of the multiple rollers 7. In some embodiments, a chain can be used to drive the multiple rollers 7 to be connected, and the rotation of the rollers 7 can be achieved by a motor. In other embodiments, a belt can be used to drive the multiple rollers 7 to be connected.

[0041] In addition, the embodiment of the utility model does not limit the specific structure of the end push assembly 6. In some embodiments, the end push assembly 6 can be provided with a cylinder on the bracket 4, and a push block 602 is installed on the extended end of the cylinder, and the push block 602 is rotatably connected with the extended end of the cylinder. When the battery pack 3 needs to be pushed, the push block 602 rotates toward the battery pack 3 to achieve contact between the push block 602 and the battery pack 3, and the battery pack 3 is pushed by the extension of the cylinder. In the above embodiment, the cylinder can be an electric cylinder, a hydraulic cylinder, or a motor, and a motor is provided between the cylinder and the push block 602 to realize the rotation function of the push block 602.

[0042] In addition, in the embodiment of the utility model, an anti-skid layer is provided on the roller 7. The anti-skid layer can be made of a rubber layer of rubber material to increase the friction between the roller 7 and the battery pack 3, which is beneficial to reduce the slipping phenomenon when transporting the battery pack 3 and reduce the wear on the bottom of the battery pack 3.

[0043] In use, a plurality of rollers 7 arranged in parallel and used to push the battery pack 3 are installed on the bracket 4. The rollers 7 are driven by a chain. A motor for driving the rollers 7 to rotate is installed on the bracket 4. When the battery pack 3 is located on the rollers 7, the rotation of the rollers 7 can drive the battery pack 3 to move. That is to say, when it is necessary to move the battery pack 3 onto the cluster rack 1, it can be automatically pushed, avoiding the need for workers to push by hand, reducing the labor intensity and cost of workers. The centering assembly 5 includes two side plates 502 and a centering driving member 501, which are used to position the battery pack 3 and are respectively located at both ends of the rollers 7. The centering driving member 501 is used to drive the two side plates 502 to approach or move away from each other. Driving the two side plates 502 to approach by the centering driving member 501 is beneficial to place the battery pack 3 in the middle position of the bracket 4, avoiding the situation where the battery pack 3 cannot correctly enter the cluster rack 1 due to the battery pack 3 being skewed or having a large deviation, and at the same time effectively avoiding the damage of the battery pack 3 during movement. The end pushing assembly 6 is installed at one end of the bracket 4 where it separates from the battery pack 3. After the rollers 7 push the battery pack 3 to separate from the rollers 7, the end pushing assembly 6 is used to push the battery pack 3 out of the bracket 4, avoiding the situation where the tail end of the battery pack 3 leaks out of the cluster rack 1, which is beneficial to improving the neatness of the placement of the battery pack 3.

[0044] Please refer to Figures 1 - 4 , in order to avoid the risk of the battery pack 3 falling during the movement of the bracket 4, in some embodiments, a limiting mechanism 8 is further included. The limiting mechanism 8 is used to limit the movement of the battery pack 3 in a direction perpendicular to the rollers 7. That is to say, the above-mentioned limiting function is achieved through the limiting mechanism 8 to avoid the accidental falling of the battery pack 3.

[0045] In some embodiments, the limiting mechanism 8 includes a baffle 801 and a limiting air cylinder 803. The baffle 801 is installed at one end of the bracket 4 away from the end pushing assembly 6. That is to say, the baffle 801 is fixed on the bracket 4 and is located on the side away from the side of the bracket 4 for pushing the battery pack 3 out. Therefore, the baffle 801 can be fixed in this direction to reduce costs. A stopper 802 is installed on the limiting air cylinder 803. When the battery pack 3 is located on the bracket 4, the limiting air cylinder 803 extends to limit the battery pack 3. That is to say, the limiting air cylinder 803 drives the stopper 802 to move up and down to achieve the functions of limiting and canceling the limit of the battery pack 3. When it is necessary to push the battery out of the bracket 4, the limiting air cylinder 803 contracts, driving the stopper 802 to move down, thereby canceling the limiting function of the battery pack 3.

[0046] It should be noted that the description of the limiting air cylinder 803 in the embodiments of the present invention is not a fixed limitation. In some embodiments, an electric cylinder, a hydraulic cylinder, etc. can be used instead.

[0047] In addition, in the embodiment of the utility model, soft materials such as rubber and silicone can be installed on the stopper 802 to help reduce the wear on the battery pack 3.

[0048] Please refer to Figure 1 In order to further increase the stability of the two side panels 502 during movement, in some embodiments, the centering component 5 also includes a plurality of slide rails 503, which are arranged parallel to the axis of the roller 7, and the two side panels 502 are slidably matched with the slide rails 503, that is, the two side panels 502 are respectively slidably installed on the slide rails 503 on both sides to increase their stability during movement.

[0049] Please refer to Figure 4 In some embodiments, the end pushing assembly 6 includes a pushing member 601, a pushing block 602 and a tightening member 603. The pushing member 601 is used to push the battery pack 3 to move in a direction perpendicular to the axis of the roller 7 and detach from the bracket 4. The tightening member 603 is used to drive the pushing block 602 to move in the direction of the roller 7. The pushing member 601 can push the tightening member 603 to move, that is, the pushing member 601 can push the tightening member 603 to move in a direction perpendicular to the axis of the roller 7 and push the battery pack 3 to detach from the bracket 4, and the tightening member 603 can drive the pushing block 602 to move in the direction of the axis of the roller 7. Therefore, the tightening member 603 can ensure that the battery pack 3 will not be affected by being pushed away during the process of moving to the bracket 4.

[0050] It should be noted that the embodiment of the utility model does not limit the specific structure of the pushing member 601 and the pressing member 603. In some embodiments, it can be a cylinder, an electric cylinder or a hydraulic cylinder, or a motor, such as a DC brush motor or a stepper motor.

[0051] In some embodiments, the centering drive member 501, the pushing member (601) and the tightening member 603 use a cylinder to achieve the corresponding pushing function through the extension and retraction of the cylinder, or use an electric cylinder to achieve the corresponding pushing function through the extension and retraction of the electric cylinder, or use a motor-screw mechanism to achieve the corresponding pushing function through the rotation of the screw driven by the motor.

[0052] It should be noted that in the embodiment of the utility model, a motor-screw mechanism is adopted, and the axis of the screw can be set along the moving direction of the required moving part, and the screw is installed on the bracket 4. The motor drives the screw to rotate, and the screw slider is threadedly matched on the screw. The screw slider is fixedly connected to the required moving part, thereby realizing the driving of the moving part.

[0053] In some embodiments, a top plate 9 located below the roller 7 is installed on the bracket 4, and a gap is left between the top plate 9 and the roller 7 to avoid friction between the top plate 9 and the roller 7 when the bracket 4 is lifted by the top plate 9.

[0054] In some embodiments, an anti-slip surface or anti-slip protrusions may be provided on the side of the top plate 9 facing away from the roller 7 to increase the stability during the process of lifting the bracket 4 and moving it.

[0055] In addition to the above-mentioned battery pack 3, roller 7, and bracket 4, the present utility model also provides a battery pack cluster rack placement system, which includes the above-mentioned battery pack roller tray, and further includes a cluster rack 1 for storing the battery pack 3, and an AGV cart 2 for driving the tray to move.

[0056] The steps to implement the above system include:

[0057] 1) Arrange several brackets 4 neatly;

[0058] 2) Place the battery pack 3 on the corresponding empty bracket 4 through a hoisting device;

[0059] 3) The AGV cart 2 scans the battery information on the bracket 4 to be moved;

[0060] 4) The AGV cart 2 moves the battery pack 3 to the corresponding position on the cluster rack 1 according to the scanned battery pack 3 information;

[0061] 5) The roller 7 on the bracket 4 pushes the battery pack 3 towards the cluster rack 1;

[0062] 6) The end pushing group on the bracket 4 pushes the battery pack 3 to an appropriate depth on the cluster rack 1;

[0063] 7) The AGV cart 2 drives the empty bracket 4 back to the original position.

[0064] It should be noted that in the embodiments of the present utility model, the AGV cart 2 is one of the commonly used automated devices in logistics warehousing. Its function is to replace manual labor and achieve automatic transportation and handling of goods. That is to say, the AGV cart 2 is a mature technology at present, and it has mature means to achieve the above functions, so it will not be elaborated here.

[0065] Through the cooperation of the above-mentioned components and the execution of the above steps, the automation of placing the battery pack 3 on the cluster rack 1 is achieved.

[0066] That is to say, the key point of the embodiment of the present utility model is that several rollers 7 arranged in parallel and used to push the battery pack 3 are installed on the bracket 4. When the battery pack 3 needs to be moved to the cluster rack 1, it can be automatically pushed, avoiding the need for manual pushing by workers, reducing the labor intensity and cost of workers. The two side plates 502 are driven to approach by the central driving member 501, which is beneficial to place the battery pack 3 in the middle position of the bracket 4, avoiding the situation that the battery pack 3 cannot correctly enter the cluster rack 1 due to the battery pack 3 being skewed or having a large deviation, and at the same time effectively avoiding the damage of the battery pack 3 during movement. After the roller 7 pushes the battery pack 3 and separates from the roller 7, the end pushing assembly 6 is used to push the battery pack 3 out of the bracket 4, avoiding the situation that the tail end of the battery pack 3 leaks out of the cluster rack 1, which is beneficial to improving the neatness of the placement of the battery pack 3.
