Technical Field

[0001] This utility model relates to the field of battery production technology, specifically, to an automatic battery box assembly device. Background Technology

[0002] A battery box is a device specifically designed for storing, protecting, and managing batteries. It is commonly used in various battery-powered devices or systems, such as electric vehicles, renewable energy storage systems, power tools, and other electronic devices. The battery box manufacturing process involves the automated assembly of various components (such as battery frames and base plates) into a complete battery box. With the continuous development of battery technology and demand, especially in the fields of new energy vehicles, energy storage systems, and consumer electronics, assembly equipment plays a crucial role in improving production efficiency, ensuring product quality, and reducing labor costs.

[0003] Existing battery box assembly equipment typically involves manual alignment and splicing of the battery frame and base plate, followed by assembly by a robotic arm; alternatively, a robotic arm can be added to replace manual alignment and splicing. Both approaches have drawbacks. In the first approach, manual transfer and alignment are physically demanding for workers, and alignment accuracy is difficult to guarantee, potentially affecting subsequent assembly operations. In the second approach, the robotic arm stops working after completing the transfer and alignment tasks, resulting in low utilization and overall low assembly efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic battery box assembly device to solve the problems of low overall assembly efficiency and high labor intensity of existing assembly equipment.

[0005] This utility model is achieved through the following technical solution: an automatic battery box assembly device, comprising:

[0006] An assembly system includes a first robotic arm, a second robotic arm, a nail feeder, an assembly tool, a suction cup, a first support platform, and a second support platform. The assembly tool is placed on the first support platform, and the suction cup is placed on the second support platform. During operation, the assembly tool is installed on the first robotic arm, and either the assembly tool or the suction cup is installed on the second robotic arm. The suction cup is used to pick up the bottom plate of the battery box, and the assembly tool is used for assembly operations.

[0007] The battery frame loading unit includes a base, a support platform, and a drive source. The support platform is used to load the battery frame and is driven by the drive source to slide on the base to switch work positions.

[0008] The base plate loading part includes a vehicle body and a guide part. The vehicle body is used to load the battery box base plate, and the vehicle body is guided and limited by the guide part to maintain a fixed position.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Example 1:

[0027] This embodiment provides an automatic battery box assembly device, specifically as follows: Figures 1-3 As shown, the system includes: an assembly system, a battery frame loading section 2, a base plate loading section 3, and an electrical cabinet 101. The assembly system includes a first robotic arm 103, a second robotic arm 104, an air tube support 105, a nail feeder 106, an assembly tool 107, a suction cup 108, a first support platform 109, and a second support platform 110. The assembly tool 107 is placed on the first support platform 109, and the suction cup 108 is placed on the second support platform 110. During operation, the assembly tool 107 is installed on the first robotic arm 103, and the assembly tool 108 is installed on the second robotic arm 104. The assembly tool 107 is used for assembly operations, and the battery box loading part 2 includes a base, a support, and a drive source. The support is used to load the battery box and slides on the base under the drive source to switch work positions. The base plate loading part 3 includes a vehicle body and a guide. The vehicle body is used to load the battery box base and is guided and limited by the guide to maintain a fixed position. The electrical cabinet 101 is used to control the electrical connection and disconnection of the assembly system, the battery box loading part 2, and the base plate loading part 3.

[0028] The first robotic arm 103, the second robotic arm 104, the nail feeder 106, the assembly tool 107, and the suction cup 108 mentioned above are all commercially available products, and their specific structures and principles will not be described in detail here.

[0029] During operation, the operator first places the multi-layer battery box base plate on the vehicle body, then guides the vehicle body to the designated workstation. Simultaneously, at the loading and unloading station, the battery frame to be assembled is placed on the support platform. The support platform is then moved to the assembly station by the drive source. At this time, the second robotic arm 104 starts first, connecting with the suction cup 108 on the second support platform 110. The suction cup 108 then adsorbs the battery box base plate on the vehicle body and transfers it to the battery frame on the support platform, aligning the base plate with the battery frame. Afterward, the second robotic arm 104 unloads the suction cup 108 back onto the second support platform 110. At this time, both the second robotic arm 104 and the first robotic arm 103 start, and each of the first robotic arm 103 and the second robotic arm 104 is connected to an assembly tool 107. Then, driven by the first robotic arm 103 and the second robotic arm 104, the two assembly tools 107 begin to assemble the battery frame and the base plate. During this process, the nail feeder 106 continuously provides rivets or screws to the assembly tools 107. After the assembly is completed, the first robotic arm 103 does not remove the assembly tool 107, while the second robotic arm 104 removes the assembly tool 107 and begins to connect with the suction cup 108. At this time, the support platform transfers the assembled battery box to the loading and unloading station, where workers take it away and place a new battery frame. This process is repeated in this cycle.

[0030] With the above settings, the second robotic arm 104 can be connected to either the assembly tool 107 or the suction cup 108. That is, the second robotic arm 104 can not only transfer and align the battery box bottom plate, but also cooperate with the first robotic arm 103 to complete the assembly operation. This maximizes the use of the second robotic arm 104, effectively reduces the intensity of manual labor, improves docking accuracy, and greatly improves assembly efficiency.

[0031] Example 2:

[0032] This embodiment further expands upon the above embodiment by extending the base, specifically as follows: Figure 3 , Figure 6 As shown, the base includes a transfer base 201 and a fixed base 202. The drive source includes a transfer cylinder 204, one end of which is mounted on the transfer base 201 and the other end on the support platform. Multiple clamps 203 are mounted on the fixed base 202 to limit the battery frame in the assembly station. The clamps 203 do not interfere with the placement of the base plate. The clamps 203 are commercially available and their specific operating principles will not be described in detail here.

[0033] The telescopic movement of the transfer cylinder 204 causes the support platform to move on the transfer base 201, allowing the support platform to switch back and forth between the loading / unloading station and the assembly station. The clamp 203 presses the base plate and battery frame together after the suction cup 108 aligns them, preventing relative movement between the base plate and battery frame and ensuring the normal operation of the subsequent assembly tool 107.

[0034] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0035] Example 3:

[0036] This embodiment further expands the support platform based on the above embodiment, specifically as follows: Figure 6 As shown, the support platform includes a support plate 207, which is slidably connected to the transfer base 201. The support plate 207 is provided with a plurality of first guide plates 205 and first support blocks 206. The clamp 203 cooperates with the first support blocks 206 to fix the battery frame.

[0037] The first guide plate 205 is used to guide the battery frame and ensure that the battery frame is accurately positioned on the support platform. The first support block 206 is used to support the battery frame. When the clamp 203 presses down on the base plate, the clamp 203 will support the battery frame. The two work together to clamp the base plate and the battery frame.

[0038] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0039] Example 4:

[0040] This embodiment further expands the vehicle body based on the above embodiment, specifically as follows: Figure 4 As shown, the vehicle body includes a frame 301, on which are mounted casters 302, a second guide plate 303, a positioning pin 304, a second support block 305, and a handle 306. The positioning pin 304 engages with a positioning hole on the bottom plate of the battery box, and the second support block 305 supports the bottom plate of the battery box.

[0041] The second support block 305 is used to limit the bottom plate, ensuring that when the bottom plate is placed on the vehicle body manually, the positioning pin 304 can cooperate with the positioning hole on the bottom plate; pulling the handle 306 can realize the movement of the vehicle body; the universal wheel 302 is provided with sound-absorbing cotton, which can reduce the noise when the universal wheel 302 rolls.

[0042] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0043] Example 5:

[0044] This embodiment further expands the guiding part based on the above embodiment, specifically as follows: Figure 4 , Figure 5 As shown, the guide section includes a slot block 308, a locking cylinder 309, and two symmetrically arranged third guide plates 312. The third guide plates 312 are used to guide the vehicle body. A pin 307 is installed on the vehicle body. The pin 307 cooperates with the slot block 308. A locking motor 311 is installed on the locking cylinder 309. A locking block 310 is installed on the locking motor 311. The locking block 310 is used to limit the position of the vehicle body.

[0045] When the worker pushes the handle 306 to push the frame 301 towards the slot block 308, the third guide plates 312 on both sides guide the frame 301 to ensure that the pin 307 can be inserted into the slot block 308, thereby limiting the lateral position of the vehicle body. After the pin 307 is inserted into the slot block 308, the locking motor 311 starts, rotating the locking block 310. Then, the locking cylinder 309 drives the locking motor 311 to retract. At this time, the locking block 310 will press down on the frame 301, limiting the longitudinal position of the vehicle body within the chassis. The vehicle body is now completely limited, ensuring the correct position of the base plate. When the base plate on the vehicle body is used up, the locking cylinder 309 extends, and at the same time, the locking motor 311 reverses, driving the locking block 310 to reset, so that the locking block 310 will not interfere with the movement of the frame 301. At this time, the worker can manually pull the handle 306 to pull out the vehicle body, and then install the base plates in batches again.

[0046] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0047] Example 6:

[0048] This embodiment further extends the above embodiment, specifically as follows: Figure 1 As shown, it also includes a fence 102, which surrounds the assembly system, the battery frame loading part 2, and the base plate loading part 3. The fence 102 is provided with an opening for the vehicle body and the platform to enter and exit.

[0049] Using fence 102 to enclose the entire equipment provides protection. On the one hand, it prevents unauthorized personnel from entering and being injured by impacts from the first robotic arm 103 and the second robotic arm 104. On the other hand, it reduces the impact of external objects on the overall equipment and improves its operational stability.

[0050] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
