[0002] Battery pack riveting is a common connection technology used in the assembly of battery modules, widely applied in the manufacturing of battery packs for electric vehicles (EVs) and energy storage systems. Riveting uses rivets to firmly connect the battery pack casing to the internal structure, ensuring that it will not loosen or be damaged during operation. It offers advantages such as high efficiency, stability, and strong sealing, making it suitable for high-intensity working environments, such as the vibration and thermal expansion requirements of electric vehicles.
[0003] Existing riveting equipment typically involves a one-to-one pairing of the riveting machine and the battery box. After the riveting operation is completed, the battery box needs to be removed and replaced with a new one for the next round of riveting. During this process, the riveting equipment is in a stopped state. Since it takes a long time for operators to load and unload materials, the efficiency of the riveting operation is low, and it is impossible to carry out loading and unloading operations without stopping the riveting equipment.

[0026] 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.
[0027] 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.
[0028] Example 1:
[0029] This embodiment provides an automatic riveting workstation for battery boxes, specifically as follows: Figure 1 , Figure 2 , Figure 3 , Figure 6As shown, the system includes: an assembly system, a loading unit 2, and an electrical cabinet 101. The assembly system includes multiple robotic arms 103 and a robotic arm control cabinet 104. The robotic arm control cabinet 104 controls the movements of the robotic arms 103. Each robotic arm 103 is equipped with a riveting tool and is used for riveting operations. The loading unit 2 includes a transfer unit 21 and a loading unit 22. The loading unit 22 is mounted on the transfer unit 21, and the transfer unit 21 supports and adjusts the position of the loading unit 22. The loading unit 22 is used to load the battery box. The transfer unit 21 includes a base 211, on which a motor 212 and a loading bracket 213 are mounted. The motor 212 is connected to the loading bracket 213 in a transmission manner. Multiple loading units 22 are symmetrically mounted on the loading bracket 213. The loading unit 22 includes a loading base plate 221, on which multiple limiting clamps 222 and support blocks 227 are mounted. The electrical cabinet 101 is used to control the electrical on / off distribution of the assembly system and the loading unit 2.
[0030] The electrical cabinet 101, robotic arm 103, robotic arm control cabinet 104, and limit clamp 222 mentioned above are all commercially available products. Their specific models and structures are readily understood by those skilled in the art and will not be described in detail here.
[0031] In this embodiment, there are two loading units 22. The loading unit 22 closer to the robotic arm 103 is located in the working area, and the loading unit 22 farther from the robotic arm 103 is located in the loading / unloading area. There are three robotic arms 103 and three robotic arm control cabinets 104. During operation, the operator places the battery box on the loading unit 22 in the loading / unloading area and supports it with the support block 227. At the same time, the limiting clamp 222 presses the battery box onto the support block 227 to limit the battery box. After the battery box is loaded, the motor 212 is started. The motor 212 drives the loading bracket 213 to rotate half a turn, transferring the loading unit 22 in the loading / unloading area to the working area. At this time, the robotic arm 103 begins the riveting operation. At the same time, the loading unit 22, which was originally in the working area, is also transferred to the loading / unloading area. Therefore, the operator begins to remove the riveted battery box from the loading unit 22 in the loading / unloading area and reinstalls the battery box to be riveted. This cycle is repeated.
[0032] With the above settings, when the robotic arm 103 is riveting the battery box, the operator can remove the riveted battery box and load a new battery box to be riveted. This operation is carried out synchronously with the operation of the robotic arm 103 without interfering with each other, which greatly improves the efficiency of the riveting operation.
[0033] Example 2:
[0034] This embodiment further extends the above embodiment, specifically as follows: Figure 5 As shown, a positioning unit is installed on the loading base plate 221. The positioning unit includes a positioning drive source 224 and a positioning shaft 225. The positioning drive source 224 is installed on the loading base plate 221, and the positioning shaft 225 is installed at the output end of the positioning drive source 224. The positioning shaft 225 cooperates with the positioning hole on the battery box. The positioning drive source 224 can be a cylinder, a linear motor, or other power source that can drive the positioning shaft 225 to perform linear movements.
[0035] When the operator installs the battery box on the loading unit 22, the positioning drive source 224 is activated. The positioning drive source 224 pushes out the positioning shaft 225, which is then embedded into the positioning hole on the battery box. This corrects the specific position of the battery box, ensuring that the robotic arm 103 can be aligned with the riveting hole during operation, thus improving accuracy.
[0036] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0037] Example 3:
[0038] This embodiment further extends the above embodiment, specifically as follows: Figure 4 , Figure 5 As shown, a guide correction plate 223 is installed on the loading base plate 221, and the guide correction plate 223 is used for guiding the multi-battery box.
[0039] Before positioning the battery box with the positioning shaft 225, the battery box is first preliminarily positioned using the guide correction plate 223 to ensure that the deviation between the positioning shaft 225 and the positioning hole on the battery box is within a predetermined range, preventing the positioning shaft 225 from failing to fit with the positioning hole, reducing adjustment time, and thus improving the loading efficiency of the battery box.
[0040] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0041] Example 4:
[0042] This embodiment further extends the above embodiment, specifically as follows: Figure 5 As shown, a buffer plate 226 is installed on the guide correction plate 223, and an anti-slip pad 228 is installed between the loading base plate 221 and the support block 227.
[0043] By setting the buffer plate 226, the contact between the battery box and the guide correction plate 223 is buffered, preventing the guide correction plate 223 from directly contacting the battery box and causing scratches or even deformation of the battery box. Since the support block 227 is also designed with a limiting groove, it also has a certain limiting ability for the battery box. By setting the anti-slip pad 228, the friction between the support block 227 and the loading base plate 221 is increased, preventing the support block 227 from deflecting on the loading base plate 221. This would prevent the limiting groove of the support block 227 from not fitting the battery box when it is supported by the support block 227, resulting in loading misalignment.
[0044] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0045] Example 5:
[0046] This embodiment further extends the above embodiment, specifically as follows: Figure 3 As shown, the transfer unit 21 also includes a reducer 214, the output end of the motor 212 is connected to the input end of the reducer 214, and the output end of the reducer 214 is connected to the loading bracket 213.
[0047] The motor 212 drives the reducer 214, which in turn drives the loading bracket 213. The reducer 214 not only increases torque but also effectively reduces the impact force during power transmission and reduces the pressure on mechanical parts caused by excessively high speeds. When transferring battery boxes of different weights, adjusting the power output of the reducer 214 can better control the rotation speed of the loading bracket 213.
[0048] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0049] Example 6:
[0050] This embodiment further extends the above embodiment, specifically as follows: Figure 1 As shown, the assembly system also includes a tool compartment 105, which stores the tools required for riveting operations for replacement by the robotic arm 103. The tool compartment 105 is a commercially available product used in conjunction with the robotic arm 103. The specific process and principle of the robotic arm 103 changing riveting tools in the tool compartment 105 are easily understood by those skilled in the art and will not be elaborated here.
[0051] The tools stored in the tool compartment 105 include, but are not limited to, glue guns, cutters, and rivet guns. When the robotic arm 103 begins working on the battery box, it first switches to a glue gun in the tool compartment 105 and applies glue to the areas to be riveted. Then, the robotic arm 103 returns to the tool compartment 105, removes the glue gun, and replaces it with a rivet gun to begin the riveting operation. After riveting is completed, the robotic arm 103 returns to the tool compartment 105, removes the rivet gun, and then replaces it with a cutter to cut off any screws that were too long during the riveting operation. Finally, the robotic arm 103 returns to the tool compartment 105, removes the cutter, replaces it with a glue gun, and can then begin a new round of work.
[0052] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0053] Example 7:
[0054] This embodiment is a further extension of the above embodiment. As shown in the figure, it also includes a protective railing 102, which surrounds and protects the assembly system and the loading part 2.
[0055] By setting up the guardrail 102, the guardrail 102 can intercept externally rolling objects, preventing some objects from rolling into the work area and causing impact to the equipment due to operator error.
[0056] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0057] 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.
