Description

Technical Field

[0001] The utility model relates to the technical field of new energy batteries, in particular to a battery pack stacking device. Background Art

[0002] As an important component of the battery module in new energy vehicles, the processing of battery packs has become particularly important. In particular, as new energy vehicles develop faster and faster, higher requirements are placed on the production speed of battery packs. After the processing of existing battery packs is completed, they need to be collected and palletized.

[0003] At present, during the palletizing process of battery packs, manual or robot-related equipment is usually used to palletize the battery packs. Among them, the robot needs to extend the battery pack into the designated position of the material rack during the palletizing process. As a result, during the loading process of the existing palletizing robot, the docking accuracy between the connecting rod and the material rack is not high, and it is not easy to load the material. This is because when the palletizing device is conveying materials to the material rack, if the palletizing device is always in operation, the material will be directly transported out, causing problems such as material falling, which is not conducive to direct loading; if the palletizing device is always started and stopped, it is not conducive to the long-term stable operation of the system. It can be seen that the applicability of the existing battery pack palletizing device in actual use is poor.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to ordinary technicians in this field. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to solve the problem that during the palletizing process of the existing battery packs, the palletizing device is not easy to load and the docking accuracy between the connecting rod of the palletizing device and the material rack is not high.

[0006] The utility model solves the above technical problems through the following technical means:

[0007] A battery pack palletizing device comprises a frame, a transport mechanism, and a driving rod. The front end of the frame is connected to at least two connecting rods, and the top surfaces of at least two of the connecting rods constitute a battery pack support surface. The connecting rods have slots running through the length direction and the top surface. The transport mechanism and the driving rod are both slidably connected in the slots. One end of the driving rod is connected to the connecting rod through an elastic member. The transport mechanism is located above the driving rod, and the transport mechanism and the driving rod are linked by a plurality of connecting rods.

[0008] In the utility model, the top surface of the connecting rod constitutes the supporting surface of the battery pack. When the rack transports the battery pack, the supporting surface of the battery pack supports and transports the battery pack. At this time, the top surface of the transport mechanism can be slightly lower than the supporting surface of the battery pack. When palletizing is required, the driving rod compresses the elastic member, and the driving rod contracts into the slot. The contraction action of the driving rod is transmitted to the transport mechanism through the connecting rod, so that the transport mechanism transports and supports the battery pack upward, and the transport mechanism acts to transport the battery pack out. In the utility model, as the position of the manipulator is advanced, the driving rod contracts to realize the linkage of the transport mechanism, and the conveyor belt is higher than the supporting surface of the connecting rod. The battery pack is moved to the supporting platform through the rotation of the conveyor belt, thereby realizing accurate palletizing of the battery pack. It can effectively improve the problem that the existing battery pack is not easy to load during the palletizing process, and the connection rod of the palletizing device and the material rack have low docking accuracy.

[0013] Preferably, the transport mechanism comprises a connecting frame, two conveying wheels, and a conveyor belt, the connecting frame is limited in the slot and can slide along the slot, the conveying wheels are rotatably connected to the connecting frame, and the conveying wheels are connected to the conveyor belt.

[0014] Preferably, a plurality of connecting rods are arranged in parallel, one end of each connecting rod is hinged to the driving rod, and the other end of each connecting rod is hinged to the connecting frame.

[0015] Preferably, when the rack supports the battery pack, the upper conveying plane of the conveyor belt is flush with the supporting surface of the battery pack; when the rack transports the battery pack, the upper conveying plane of the conveyor belt is higher than the supporting surface of the battery pack.

[0016] Preferably, it further comprises a material rack, wherein the material rack comprises a plurality of support platforms arranged at intervals.

[0017] Preferably, a plurality of guide wheels are rotatably connected to the support platform.

[0018] Preferably, the bottom of the support platform is connected to a limiting rod, and the limiting rod extends outside the support platform.

[0019] The rotation of the conveyor belt cooperates with the guide wheel of the support platform to move the battery pack to the support platform, thereby achieving accurate palletizing of the battery pack; the conveyor belt can always keep running during the whole process, thereby avoiding the stacking device from starting and stopping all the time, which is not conducive to the long-term stable operation of the system.

[0020] Through the conveyor belt, battery packs of different sizes can be transported and stacked. At the same time, based on the limiting effect between the trigger rod and the limiting rod, the docking accuracy between the connecting rod and the rack can be improved.

When palletizing is required, the driving rod compresses the elastic part, and the driving rod contracts into the slot. The contraction action of the driving rod is transmitted to the transport mechanism through the connecting rod, so that the transport mechanism transports and supports the battery pack upward, and the transport mechanism moves to transport the battery pack out. In the utility model, as the position of the manipulator is advanced, the driving rod contracts to realize the linkage of the transport mechanism, and the conveyor belt is higher than the supporting surface of the connecting rod.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Embodiment 1:

[0037] like Figures 1 to 5 , a battery pack palletizing device includes a palletizing robot, a rack 100, a transport mechanism and a driving rod 120. Among them, the rack 100 is connected to the palletizing robot, and the position of the rack 100 can be adjusted by the palletizing robot. Therefore, for the palletizing robot, it is allowed to be determined according to actual needs. For example, the palletizing robot can adopt a four-axis robot arm, a six-axis robot arm, etc., of course, it is not limited to this. The present embodiment has strong adaptability and can adapt to other transportation occasions. It should be noted that a connecting rod 110 is connected to the rack 100. During the transportation of the rack 100, the battery pack 10 that needs to be palletized is supported on the battery pack support surface composed of two connecting rods 110.

[0038] Among them, the rack 200 for storing the battery packs 10 is located on one side of the palletizing robot, and a plurality of support platforms 210 are provided on the rack 200. When the battery pack 10 is stored through the rack 200, the battery pack 10 is located on the support platform 210. It can be understood that the rack 200 may allow a frame structure, and a plurality of support platforms 210 are distributed in layers on the rack 200. In order to avoid sliding friction between the battery pack 10 and the support platform 210 during storage, thereby causing scratches on the battery pack 10. Therefore, it is allowed to provide a plurality of guide wheels on the support platform 210, and when the battery pack 10 is located on the support platform 210, it is allowed to guide the battery pack 10 through the guide wheels. That is, the transportation mechanism and the guide wheels work together to realize the transportation of the battery pack 10.

[0039] In this embodiment, the connecting rods 110 include two groups, and the two groups of connecting rods 110 are symmetrically connected to the rack 100. At the same time, the top of the connecting rods 110 is a horizontal support surface, and the support surfaces on the two groups of connecting rods 110 are on the same horizontal plane, together forming a battery pack support surface. Therefore, the battery pack 10 for palletizing is located on the battery pack support surface, so as to be transported to the support platform 210 of the corresponding material rack 200 by the palletizing robot.

[0040] Specifically, a transport mechanism is also connected to the connecting rod 110, which allows the battery pack 10 to be transported through the transport mechanism. Among them, the transport mechanism includes a connecting frame 150 and a conveying wheel 151 arranged on the connecting frame 150. The conveying wheel 151 includes two groups, and the conveying wheel 151 and the connecting frame 150 are rotatably connected. At the same time, a conveyor belt is tensioned and connected between the two groups of conveying wheels 151, and the transport plane of the conveyor belt is arranged parallel to the supporting surface on the connecting rod 110. Therefore, when the battery pack 10 contacts the conveyor belt, the battery pack 10 can be transported by the conveyor belt. It should be noted that a driving mechanism is also connected to any conveying wheel 151, and the conveyor belt can be driven to rotate by the driving mechanism.

[0041] The connecting frame 150 is slidably connected to the connecting rod 110, and a driving rod 120 is also provided in the connecting rod 110. The driving rod 120 is slidably connected to the connecting rod 110, and the driving rod 120 can drive the connecting frame 150 to slide relative to the connecting rod 110 during the sliding process.

[0042] The connecting rod 110 is provided with a notch 1101, which is a U-shaped groove with the opening facing upward, and the front end of the notch 1101 is empty. The front end in this embodiment refers to Figure 41101, and the connecting frame 150 is located in the slot 1101. At the same time, the connecting frame 150 is slidably connected to the connecting rod 110 in the slot 1101. It should be noted that when the connecting frame 150 slides in the slot 1101, the conveying surface of the conveyor belt on the connecting frame 150 can be allowed to be higher than the supporting surface.

[0043] A plurality of parallel connecting rods 140 are provided between the driving rod 120 and the connecting rod 110, one end of the connecting rod 140 is hinged to the driving rod 120, and the other end of the connecting rod 140 is hinged to the connecting rod 110. Therefore, when the driving rod 120 is sliding, the connecting frame 150 can be driven to slide relative to the connecting rod 110 through the connecting rod 140.

[0044] Specifically, the battery pack palletizing device further includes a reset spring 130 and a trigger rod 121, and the reset spring 130 and the trigger rod 121 are respectively located at the two ends of the connecting rod 110. Among them, the reset spring 130 is located between the connecting rod 110 and the driving rod 120, and the reset spring 130 makes the connecting rod 110 not carry the battery pack 10, and the transport mechanism is located below the support surface. It can be understood that it is allowed to fix the limit rod 211 on the support platform 210 on the material rack 200. When the palletizing robot drives the connecting rod 110 and the connecting rod 110 carries the battery pack 10, and the battery pack 10 is palletized in the material rack 200, the limit rod 211 can be used to contact the driving rod 120 in advance. As the position of the robot is advanced, the limit rod 211 can compress the reset spring 130 through the driving rod 120, and at the same time, the limit rod 211 drives the connecting frame 150 to move relative to the connecting rod 110 through the connecting rod 140 during the movement. When the conveyor belt on the connecting frame 150 is higher than the supporting surface of the connecting rod 110, the battery pack 10 is moved to the supporting platform 210 by the rotation of the conveyor belt, thereby realizing accurate palletizing of the battery pack 10. Therefore, by raising and lowering the conveyor belt, the conveying can always remain in operation. This avoids the stacking device from constantly starting and stopping, which is not conducive to the long-term stable operation of the system. It can be understood that through the transportation function of the conveyor belt, battery packs 10 of different sizes can also be transported and palletized. At the same time, based on the limiting function between the trigger rod 121 and the limiting rod 211, the docking accuracy between the connecting rod 110 and the rack 200 can be improved.

[0045] In this embodiment, when the rack 100 transports the battery pack 10, the battery pack support surface supports and transports the battery pack 10. At this time, the top surface of the transport mechanism can be slightly lower than the battery pack support surface. When palletizing is required, the drive rod 120 compresses the elastic member, and the drive rod 120 contracts into the slot 1101. The contraction action of the drive rod 120 is transmitted to the transport mechanism through the connecting rod 140, so that the transport mechanism transports and supports the battery pack 10 upward, and the transport mechanism moves to transport the battery pack 10 out. This embodiment can effectively improve the problem that the existing battery pack 10 is not easy to load during the palletizing process, and the docking accuracy between the connecting rod 110 of the palletizing device and the rack 200 is not high.

[0046] Embodiment 2:

[0047] like Figure 5 As shown, the battery pack stacking device also includes a limiting rod 211 used in conjunction with the driving rod 120.

[0048] The limiting rod 211 may be connected below the supporting platform 210 , and the limiting rod 211 extends outward from the supporting platform 210 .

[0049] By bringing the limiting rod 211 into contact with the driving rod 120, and as the position of the manipulator advances, the limiting rod 211 compresses the reset spring 130 through the driving rod 120. At the same time, the limiting rod 211 drives the connecting frame 150 to move relative to the connecting rod 110 through the connecting rod 140, and makes the conveyor belt on the connecting frame 150 higher than the supporting surface of the connecting rod 110. Therefore, the battery pack 10 can be moved to the supporting platform 210 by the rotation of the conveyor belt, thereby realizing accurate palletizing of the battery pack 10.

[0050] Therefore, the problem that during the palletizing process of the existing battery pack 10, the palletizing device is not easy to load and the docking accuracy between the connecting rod 110 of the palletizing device and the material rack 200 is not high can be effectively improved.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
