Description

Technical Field

[0001] This utility model belongs to the field of energy storage cabinet production technology, and in particular relates to an automatic wiring system for energy storage cabinets. Background Technology

[0002] The energy storage cabinet contains several battery packs, which need to be connected in series via connecting wires to achieve electrical transmission between them. Traditional manual wiring is not only inefficient but also prone to errors; incorrect insertion can damage the entire energy storage cabinet. To solve this problem, a related automatic insertion device needs to be designed.

[0003] In the prior art, there are related automated plugging devices. For example, Chinese Patent Publication No. CN120049258A discloses a batch automated plugging device and control method for wire harnesses. The device is equipped with a CCD camera, a first gripper, and a second gripper on a robotic arm. The CCD camera is used to identify the wire harness to be plugged in. The first gripper is used to grip the head end of the wire harness to be plugged in and plug the head end of the wire harness into a first target position on the backplane to be wired. The second gripper is used to grip the tail end of the wire harness to be plugged in and guide the wire harness along a specified trajectory on the backplane to be wired. When the wire harness reaches the second target position, the tail end of the wire harness is plugged into the second target position. This can realize the automatic plugging of the wire harness into the backplane to be wired. The above-mentioned method of plugging the two ends one after the other indicates that the wire harness is relatively short and the head and tail ends are easy to obtain. However, the efficiency of plugging the two ends one after the other is low. In this solution, on the one hand, it does not specify where the wiring harness is placed, nor does it specify where the first gripper picks up the wiring harness to be connected from; on the other hand, the connecting wires between the battery packs in the energy storage cabinet are quite long. If the first gripper is used to pick up the head end of the wiring harness to be connected first, the tail end of the wiring harness will automatically hang down without being held. After the head end is installed in the first target position, the second gripper cannot accurately pick up the tail end of the wiring harness to be connected, which makes it impossible to successfully connect the wiring harness.

[0004] Therefore, it is necessary to provide an automatic wiring system for energy storage cabinets to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to provide an automatic wiring system for energy storage cabinets, which can improve the accuracy and efficiency of wiring.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: an automatic wiring system for an energy storage cabinet, comprising a mobile trolley, a carrier mounted on the mobile trolley, and a first robotic arm and a second robotic arm. Several connecting wires are positioned within the carrier. An energy storage cabinet is mounted on one side of the mobile trolley, and several battery packs are placed inside the energy storage cabinet. The first robotic arm is used to hold the head of the connecting wire and insert the head of the connecting wire into the positive or negative terminal of the battery pack. Simultaneously, the second robotic arm is used to hold the tail of the connecting wire and insert the tail of the connecting wire into the negative or positive terminal of another battery pack, thereby achieving series connection of the battery packs.

[0007] Furthermore, the mobile trolley is equipped with a carrying platform, and several of the vehicles are installed on the carrying platform.

[0008] Furthermore, the carrier includes a base and several pairs of positioning seats arranged opposite each other on the base for positioning the connecting wire. Each pair of positioning seats includes a first positioning seat for positioning the head of the connecting wire and a second positioning seat for positioning the tail of the connecting wire.

[0009] Furthermore, several pairs of positioning seats are arranged side by side, with the first positioning seat and the second positioning seat arranged opposite each other from left to right, and an isolation groove for positioning the middle part of the connecting line is provided between the first positioning seat and the second positioning seat.

[0010] Furthermore, the second positioning seat is movably mounted on the base via an elastic component.

[0011] Furthermore, the elastic component includes a support seat disposed on the base and a connecting rod with one end disposed on the support seat and the other end movably disposed inside the second positioning seat. A spring is sleeved on the outer periphery of the connecting rod, and one end of the spring is connected to the second positioning seat and the other end is connected to the support seat. The second positioning seat is provided with a clearance for the connecting rod to move left and right.

[0012] Furthermore, the base is provided with a first limiting part on the left side of the second positioning seat and a second limiting part on the right side of the second positioning seat, and an active space is formed between the first limiting part and the second limiting part for the second positioning seat to move left and right; slide rails are provided on both the front and rear sides of the second positioning seat, and corresponding slide grooves that cooperate with the slide rails are provided on the front and rear sides of the second positioning seat.

Detailed Implementation

[0018] Please refer to Figures 1-5 This embodiment is an automatic wiring system 100 for energy storage cabinets. The automatic wiring system 100 for energy storage cabinets includes a mobile trolley 1, a carrier 2 mounted on the mobile trolley 1, and a first robotic arm 3 and a second robotic arm 4. Several connecting wires 7 are positioned inside the carrier 2. An energy storage cabinet 5 is mounted on one side of the mobile trolley 1, and several battery packs 51 are placed inside the energy storage cabinet 5. The first robotic arm 3 and the second robotic arm 4 simultaneously perform clamping and insertion actions on both ends of the same connecting wire 7. That is, the first robotic arm 3 is used to clamp the head of the connecting wire 7 and insert the head of the connecting wire 7 into the positive or negative terminal of the battery pack 51. At the same time, the second robotic arm 4 is used to clamp the tail of the connecting wire 7 and insert the tail of the connecting wire 7 into the negative or positive terminal of another battery pack 51, so as to realize the series connection of the battery packs.

[0019] The energy storage cabinet 5 has multiple layers and columns of storage compartments (not shown in the figure), and each storage compartment contains a battery pack 51. The storage cabinet 5 is existing technology, and its specific structure will not be described in detail here.

[0020] The mobile trolley 1 is preferably an AGV trolley, which can move freely between the processing station and the loading station, facilitating flexible operation. The mobile trolley 1 can also be configured as a trolley with other structures, which are not limited here.

[0021] The mobile trolley 1 is provided with a support platform 11, and several carriers 2 are installed on the support platform 11. In this embodiment, two carriers 2 are provided on the support platform 11. In other embodiments, one or more carriers 2 can be provided. When multiple carriers 2 are provided, the efficiency of insertion can be improved.

[0022] The carrier 2 includes a base 21 and several pairs of positioning seats arranged opposite each other on the base 21 for positioning the connecting line 7. Each pair of positioning seats includes a first positioning seat 23 for positioning the head of the connecting line 7 and a second positioning seat 24 for positioning the tail of the connecting line 7. In this embodiment, the first positioning seat 23 cooperates with the head of the connecting line 7, and the second positioning seat 24 cooperates with the tail of the connecting line 7. The first positioning seat 23 is provided with a first mating structure 231 that cooperates with the head of the connecting line 7, and the second positioning seat 24 is provided with a second mating structure 241 that cooperates with the tail of the connecting line 7. The first mating structure 231 and the second mating structure 241 can be holes or protrusions, which can be set according to the actual situation and are not limited here.

[0023] Several pairs of positioning seats are arranged side by side, with the first positioning seat 23 and the second positioning seat 24 positioned opposite each other. When several connecting wires 7 are positioned side by side in the positioning seats, due to the relatively long length of the connecting wires 7, in order to prevent the connecting wires 7 from crossing or tangling in the middle, several isolation grooves 25 are arranged side by side in the middle of the base 21. The isolation grooves 25 are located between the first positioning seat 23 and the second positioning seat 24 and position the middle part of the connecting wires 7. That is, for the same connecting wire 7, the head of the connecting wire 7 is positioned on the first positioning seat 23, the middle part is locked on the isolation groove 25, and the tail part is positioned on the first positioning seat 24.

[0024] Because the length of the connecting line 7 has an error, in this embodiment, the first positioning seat 23 is fixedly set and the second positioning seat 24 is movably set left and right, so as to solve the problem of difficulty in positioning the connecting line 7 due to the error in the length of the connecting line 7. The second positioning seat 24 is movably set on the base 21 left and right by the elastic component 26.

[0025] The elastic component 26 includes a support base 261 mounted on the base 21 and a connecting rod 262, one end of which is fixed to the support base 261 and the other end of which is movably disposed inside the second positioning seat 24. A spring 263 is sleeved around the outer periphery of the connecting rod 262, with one end of the spring 263 connected to the second positioning seat 24 and the other end connected to the support base 261. The second positioning seat 24 has a clearance for the connecting rod 262 to move left and right. The second positioning seat 24 can move left and right along the direction of the connecting rod 262, at which time the spring 263 is in an extended or compressed state.

[0026] Since the second positioning seat 24 has a limited range of left and right movement, and in order to prevent the second positioning seat 24 from moving out of its range and causing the spring 263 to fail, the base 21 is provided with a first limiting part 211 on the left side of the second positioning seat 24 and a second limiting part 212 on the right side of the second positioning seat 24. The distance between the first limiting part 211 and the second limiting part 212 is greater than the length of the second positioning seat 24, so that an activity space 28 for the second positioning seat 24 to move left and right is formed between the first limiting part 211 and the second limiting part 212.

[0027] To ensure the stability of the second positioning seat 24 in its left and right movements, slide rails 27 are provided on both the front and rear sides of the second positioning seat 24, and corresponding slide grooves 243 are provided on the front and rear sides of the second positioning seat 24 to cooperate with the slide rails 27.

[0028] In other embodiments, in order to adapt to connecting lines 7 of different lengths, the first positioning seat 23 and the second positioning seat 24 can both be set to move left and right. The left and right movement can be adjusted by the elastic component 26 mentioned above. Alternatively, the first positioning seat 23 and the second positioning seat 24 can be driven to move left and right by a gas driving component (not shown in the figure), such as a cylinder or a motor. The specific structure of the driving component is not limited here, and can be adjusted according to the actual situation.

[0029] In this embodiment, if the tail structure of the connecting line 7 is different, then the second positioning seat 24 is not required. Figure 3 As shown, only the head of the connecting line 7 is positioned on the first positioning seat 23, the middle part of the connecting line 7 is positioned in the isolation groove 25, and the tail of the connecting line 7 does not need to be positioned.

[0030] Both the first robotic arm 3 and the second robotic arm 4 are mounted on the mobile trolley 1 and positioned above the support platform 11. The first robotic arm 3 includes a first robotic arm 31 and a pair of first grippers 32 located at the movable end of the first robotic arm 31. The second robotic arm 4 includes a second robotic arm 41 and a pair of second grippers 42 located at the movable end of the second robotic arm 41. Both the first robotic arm 31 and the second robotic arm 41 are multi-segment rotating arms, which is prior art and will not be described in detail here. The gripping portion of the first gripper 32 is contoured to the head of the connecting line 7, and the gripping portion of the second gripper 42 is contoured to the tail of the connecting line 7. The structures of the first robotic arm 3 and the second robotic arm 4 are the same or similar; therefore, the structures of the first robotic arm 31 and the second robotic arm 41 are the same or similar, and the structures of the first grippers 32 and the second grippers 42 are the same or similar.

[0031] In this embodiment, the head and tail structures of the connecting line 7 are the same, so the structures of the first gripper 32 and the second gripper 42 are the same, and both are servo electric grippers. The structure of the servo electric gripper is existing technology and will not be described in detail here.

[0032] In other embodiments, if the head and tail structures of the connecting line 7 are different or other structures, the first gripper 32 and the second gripper 42 can be adapted according to the actual situation, or grippers with other structures can be used. The specific structures of the first gripper 32 and the second gripper 42 are not limited here.

[0033] The first robotic arm 31 is equipped with a first camera 33 at its end, and the second robotic arm 41 is equipped with a second camera 43 at its end. When gripping the connecting wire 7, the first camera 33 takes a picture of the head of the connecting wire 7, and the second camera 43 takes a picture of the tail of the connecting wire 7. The results of the pictures are transmitted to the vision detection system. The vision detection system identifies the positions of the head and tail of the connecting wire 7 and transmits the identification results to the first robotic arm 31 and the second robotic arm 41. The first robotic arm 31 and the second robotic arm 41 adjust the positions of the first gripper 32 and the second gripper 42 respectively according to the results of the pictures, so as to accurately grip the head of the connecting wire 7. When the connecting cable 7 is plugged into the battery pack 51, the first camera 33 and the second camera 43 will first take pictures of the position to be plugged into on the battery pack 51. If the head and tail of the connecting cable 7 do not correspond to the position to be plugged into, the first robotic arm 31 and the second robotic arm 41 will adjust the position of the first gripper 32 and the second gripper 42 respectively according to the picture results, thereby adjusting the posture of the head and tail of the connecting cable 7 so that the connecting cable 7 is accurately plugged into the battery pack 51.

[0034] When using the automatic wiring system 100 for energy storage cabinets provided in this solution, the energy storage cabinet 5 containing several battery packs 51 and the mobile trolley 1 are moved to the processing position. The first robotic arm 3 and the second robotic arm 4 move above the carrier 2. The first camera 33 takes a picture of the head of the connecting wire 7, and the second camera 43 takes a picture of the tail of the connecting wire 7. After determining the positions of the head and tail of the connecting wire 7, the first gripper 32 clamps the head of the connecting wire 7, while the second gripper 42 clamps the tail of the connecting wire 7. The first robotic arm 31 moves the first gripper 32, which is holding the head of the connecting wire 7, to the positive or negative terminal of the first battery pack to be connected. At the same time, the second robotic arm 41 moves the second gripper 42, which is holding the tail of the connecting wire 7, to the terminal of the first battery pack to be connected. At the negative or positive terminal of the second battery pack, the first camera 33 takes a picture to confirm the position of the positive or negative terminal of the first battery pack to be inserted. At the same time, the second camera 43 takes a picture to confirm the position of the positive or negative terminal of the second battery pack to be inserted. After the insertion position is confirmed, the first robotic arm 31 moves the first gripper 32 to insert the head of the connecting wire 7 into the positive or negative terminal of the first battery pack to be inserted. At the same time, the second robotic arm 41 moves the second gripper 42 to insert the tail of the connecting wire 7 into the negative or positive terminal of the second battery pack to be inserted, thus realizing the series connection between the first battery pack and the second battery pack. After the insertion is completed, the first robotic arm 3 and the second robotic arm 4 move above the carrier 2 to continue to hold the new connecting wire 7 for the next round of insertion.

[0035] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
