Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a positioning device. Background Technology

[0002] CTP (Cell to Pack) modules are an innovative form of power battery integration technology for electric vehicles. Their core lies in eliminating the traditional module structure and directly placing the cells within the battery pack. In existing power battery module manufacturing processes, stacking power battery modules is achieved using tooling trolleys in conjunction with AGV trolleys for transportation. Following a pre-set production rhythm and process flow, they can precisely coordinate with other automated equipment on the production line.

[0003] However, the method of using tooling carts in conjunction with AGV carts is easily affected by environmental factors. For example, uneven workshop floors, dust, or debris can cause the AGV carts to bounce and deviate from the preset route, resulting in positioning deviations and preventing the tooling plates on the tooling carts from accurately reaching the stacking station. Secondly, after the AGV carts have been running for a long time, due to wheel wear, loose mechanical parts, and other reasons, the positioning error may gradually accumulate, affecting the accuracy of stacking.

[0074] like Figure 1 and Figure 2 As shown, this utility model provides a positioning device having a first direction X, a second direction Y and a third direction Z that are perpendicular to each other, for positioning the tooling trolley 50.

[0075] Please refer to Figure 2 The tooling trolley 50 has a tooling plate 51 for carrying the battery module 60. The tooling plate 51 is provided with a first limiting plate 52 arranged at intervals along the second direction Y and a second limiting plate 53 arranged at intervals along the first direction X. The first limiting plate 52 and the second limiting plate 53 together enclose a space for placing the battery module 60.

[0076] In some implementation methods, please refer to Figure 1 and Figure 2The positioning device includes a lifting mechanism 10, a first fixed reference mechanism 20, a second fixed reference mechanism 30, and a clamping mechanism 40. Specifically, the lifting mechanism 10 includes a first sub-lifting mechanism 10a and a second sub-lifting mechanism 10b, which are spaced apart along a second direction Y. The first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b are used to receive the tooling trolley 50 along a third direction Z. When the AGV trolley transporting the tooling trolley 50 moves between the first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b, the AGV... As the trolley descends, the first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b can lift and support the tooling trolley 50 along the third direction Z, so that the tooling trolley 50 is in a suspended state; the first fixed reference mechanism 20 is connected to the second sub-lifting mechanism 10b and is used to position the tooling trolley 50 along the second direction Y; the second fixed reference mechanism 30 is located on one side of the lifting mechanism 10 along the first direction X and is used to position the tooling trolley 50 along the first direction X; the clamping mechanism 40 is connected to the first sub-lifting mechanism 10a and is configured to clamp the tooling trolley 50 along the second direction Y.

[0077] In this embodiment, the tooling carriage 50 is positioned and corrected in the second direction Y by the first fixed reference mechanism 20 in conjunction with the clamping mechanism 40, and the tooling carriage 50 is positioned and corrected in the first direction X by the second fixed reference mechanism 30. This achieves precise positioning of the tooling carriage 50 in multiple directions, ensuring the positional accuracy of the battery modules during transportation and stacking, improving production efficiency, and avoiding problems such as misalignment and tilting between modules caused by inaccurate positioning. This also improves the regularity and consistency of the internal structure of the battery pack, thereby enhancing the overall performance and safety of the battery pack.

[0078] In some implementation methods, please refer to Figure 3 The first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b have the same structure. Both the first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b include a first upright 101 and a receiving plate 104. The receiving plate 104 is slidably connected to the first upright 101 along the third direction Z. The receiving plate 104 is configured to receive the tooling plate 51 along the third direction Z. Specifically, the first upright 101 is provided with a first guide rail 102 extending along the third direction Z. The receiving plate 104 is provided with a first slider 103. The first slider 103 is slidably engaged with the first guide rail 102 so that the receiving plate 104 can move along the third direction Z.

[0079] In some embodiments, to achieve automatic lifting and lowering of the receiving plate 104, the first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b further include a first top wheel 105, a first top block 106, and a first driving member 109, such as... Figure 3As shown; wherein, the first top wheel 105 is connected to the receiving plate 104, the first top block 106 is slidably connected to the first upright 101 along the first direction X, and the first top wheel 105 abuts against the first top block 106; the first driving member 109 is disposed on the first upright 101, the first driving member 109 is connected to the first top block 106, and the first driving member 109 is configured to drive the first top block 106 to move along the first direction X; wherein, since the receiving plate 104 is slidably connected to the first upright 101, the first top wheel 105 always abuts against the first top block 106 under the action of gravity, and the first top block 106 is configured to drive the first top wheel 105 to move along the third direction Z, and the first top wheel 105 can effectively reduce the friction between the receiving plate 104 and the first top block 106.

[0080] In the above embodiment, the first support 101 is provided with a second slider 107, and the first top block 106 is provided with a second guide rail 108 extending along the first direction X. The second guide rail 108 and the second slider 107 are slidably engaged so that the first top block 106 can move along the first direction X.

[0081] In some embodiments, the output terminal of the first drive member 109 is directly connected to the first top block 106, and the first drive member 109 directly drives the first top block 106 to move along the first direction X.

[0082] In some embodiments, to ensure the stability and balance of the receiving plate 104 moving in the Z direction, at least two first top wheels 105 are provided, and the number of first top blocks 106 matches the number of first top wheels 105. For example, the receiving plate 104 has two first top wheels 105, and there are also two first top blocks 106, with both first top blocks 106 connected to the moving rod 111 to achieve synchronous movement of multiple first top blocks 106. The first top wheels 105 and the first top blocks 106 correspond one-to-one. Figure 3 As shown, when the first driving member 109 drives the moving rod 111 to move along the first direction X, the multiple first top blocks 106 can move synchronously along the first direction X, thereby acting on the corresponding first top wheel 105, so that the receiving plate 104 rises or falls stably and in a balanced manner.

[0083] In the above embodiment, in order to further ensure that the receiving plate 104 rises or falls stably and in a balanced manner, the output end of the first driving member 109 is provided with a connecting block 110, and the first top block 106 is connected to a moving rod 111 extending along the first direction X. The connecting block 110 is at least partially connected to the moving rod 111. Thus, the first driving member 109 can drive the moving rod 111 to move along the first direction X through the connecting block 110, thereby driving the first top block 106 to move along the first direction X. By setting the moving rod 111, multiple first top blocks 106 can be connected synchronously, thereby ensuring the stability and balance of the receiving plate 104 when moving in the third direction Z.

[0084] In some embodiments, to enable the receiving plate 104 to rise or fall, the first top block 106 has a first top surface 106a and a second top surface 106b, such as... Figure 3 As shown; wherein, the first top surface 106a and the second top surface 106b are arranged at intervals along the first direction X and along the third direction Z. The height of the first top surface 106a is greater than the height of the second top surface 106b. When the first top block 106 moves along the first direction X, causing the first top wheel 105 to move from the first top surface 106a to the second top surface 106b, the first top wheel 105 descends, thereby driving the receiving plate 104 to descend; when the first top block 106 moves along the first direction X, causing the first top wheel 105 to move from the second top surface 106b to the first top surface 106a, the first top wheel 105 rises. This causes the receiving plate 104 to rise; the first driving member 109 drives the first top block 106 to move along the first direction X, thereby enabling the first top wheel 105 to switch between the first top surface 106a and the second top surface 106b, thereby achieving the smooth rise or fall of the first top wheel 105, and thus the rise or fall of the receiving plate 104. The first top block 106 adopts this design, which can convert its linear motion along the first direction X into the linear motion of the receiving plate 104 in the third direction Z, which can optimize the spatial layout of the lifting mechanism 10 and avoid the interference between the components.

[0085] In some embodiments, to facilitate guiding the tooling trolley 50 between the first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b, the first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b further include a mounting plate 112 and a plurality of guide wheels 113, such as... Figure 4 As shown; specifically, the first upright 101 has mounting plates 112 on both sides opposite to each other along the first direction X; multiple guide wheels 113 are spaced apart on the mounting plates 112 along the first direction X. The guide wheels 113 are configured to guide the tooling trolley 50 into the space between the first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b. Furthermore, the guide wheels 113 act on the edge of the tooling plate 51, so as to accurately guide the tooling trolley 50 into the space between the first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b, so as to ensure the subsequent positioning accuracy.

[0086] In some implementation methods, please refer to Figure 5Understandingly, the first fixed reference mechanism 20 includes a second upright 201, a floating component 202, a reference frame 205, a second driving member 203, and a second top block 204. Specifically, the floating component 202 is connected to the second upright 201, the reference frame 205 is connected to the floating component 202, and the floating component 202 is configured to drive the reference frame 205 away from the first limiting plate 52 along the second direction Y. The second driving member 203 is connected to the second upright 201. The second top block 204 is slidably connected to the floating component 202 along the first direction X, and the second... The top block 204 is connected to the second driving member 203, which is configured to drive the second top block 204 to act on the floating assembly 202, so that the reference frame 205 moves closer to or further away from the first limiting plate 52 along the second direction Y. The floating assembly 202 converts the linear motion of the second top block 204 along the first direction X into the linear motion of the reference frame 205 along the second direction Y, and can move the reference frame 205 away from the first limiting plate 52 when the second driving member 203 is reset, thereby reducing the number of driving members and saving space.

[0087] In some implementations, such as Figure 6 As shown, the floating assembly 202 includes a support plate 2021, a linear bearing 2022, a sliding shaft 2023, and a first end plate 2024. Specifically, the support plate 2021 is connected to the second upright 201 and is arranged perpendicular to the second direction Y. The linear bearing 2022 is disposed on the support plate 2021 along the second direction Y, and the sliding shaft 2023 slides through the linear bearing 2022 along the second direction Y. The first end plate 2024 is disposed on the side of the support plate 2021 near the first limiting plate 52, and the first end plate 2024 and the sliding shaft 2023 are connected. 3. The reference frame 205 is connected to the first end plate 2024, so that the reference frame 205 can move along the second direction Y. The second top block 204 abuts against the first end plate 2024. When the second driving member 203 drives the second top block 204, it can push the reference frame 205 to move along the second direction Y and approach the first limiting plate 52, thereby providing a positioning reference in the second direction Y for the tooling trolley 50. The cooperation of the linear bearing 2022 and the sliding shaft 2023 can ensure that the reference frame 205 moves smoothly and with high precision along the second direction Y, thereby improving the positioning accuracy.

[0088] In some implementations, such as Figure 6 As shown, the support plate 2021 is provided with a third guide rail 206 on the side near the tooling trolley 50. The third guide rail 206 extends along the first direction X. The second top block 204 is provided with a third slider 207. The third slider 207 slides with the third guide rail 206 so that the second top block 204 can move along the first direction X under the drive of the second driving member 203.

[0089] In some embodiments, the floating assembly 202 further includes a second end plate 2025 and an elastic element 2026, such as Figure 6 As shown; wherein, the second end plate 2025 is located on the side of the support plate 2021 away from the reference frame 205, along the second direction Y, the second end plate 2025 and the support plate 2021 are spaced apart, and the second end plate 2025 is connected to the sliding shaft 2023; the elastic member 2026 is sleeved on the sliding shaft 2023, and along the second direction Y, the two ends of the elastic member 2026 abut against the support plate 2021 and the second end plate 2025 respectively. Under the action of the elastic member 2026, the reference frame 205 always has a tendency to move away from the first limiting plate 52, so that the second top block 204 can act on the first end plate 2024 under the drive of the second driving member 203, and then... The drive reference frame 205 moves closer to the first limiting plate 52 along the second direction Y, at which point the elastic element 2026 is in a compressed state. After the first limiting plate 52 is positioned, the second drive element 203 resets. Under the action of the elastic element 2026, the second end plate 2025 moves away from the support plate 2021 along the second direction Y, and then drives the first end plate 2024 away from the first limiting plate 52 along the second direction Y via the sliding shaft 2023. At this time, the reference frame 205 also moves away from the first limiting plate 52. The setting of the second end plate 2025 and the elastic element 2026 enables the reference frame 205 to automatically and efficiently reset after positioning, reducing the redundancy and maintenance complexity of the floating component 202.

[0090] In some embodiments, the second top block 204 is slidably disposed on the side of the support plate 2021 near the first end plate 2024 along the first direction X. The second top block 204 has a third top surface 204a and a fourth top surface 204b, such as... Figure 6 As shown; along the second direction Y, the distance between the third top surface 204a and the first end plate 2024 is less than the distance between the fourth top surface 204b and the first end plate 2024; further, the floating assembly 202 also includes a second top wheel 2027, disposed on the side of the first end plate 2024 near the support plate 2021, the second top wheel 2027 abuts against the third top surface 204a or the fourth top surface 204b; the arrangement of the second top wheel 2027 can reduce the friction between the second top block 204 and the first end plate 2024; when the second driving member 203 drives the second top block 204 to move along the first direction X, the second top... The wheel 2027 can switch between the third top surface 204a and the fourth top surface 204b. When the second top wheel 2027 abuts against the third top surface 204a, the reference frame 205 moves closer to and abuts against the first limiting plate 52 along the second direction Y. When the second top wheel 2027 abuts against the fourth top surface 204b in the second direction Y, under the action of the elastic element 2026, the reference frame 205 moves away from the first limiting plate 52, and the second top wheel 2027 and the fourth top surface 204b are always in contact. The second top block 204 adopts this design, which can optimize the spatial layout of the first fixed reference mechanism 20 and reduce redundancy and maintenance complexity.

[0091] In some embodiments, the reference frame 205, after abutting against the first limiting plate 52, serves as the positioning reference for the tooling trolley 50 in the second direction Y. To achieve the positioning of the tooling plate 51 in the second direction Y, the clamping mechanism 40 includes a clamping block 42 and a fifth driving member 43, such as... Figure 3 As shown; wherein, the clamping block 42 is slidably disposed on the first upright 101 along the second direction Y; the fifth driving member 43 is disposed on the first upright 101, and the fifth driving member 43 is connected to the clamping block 42. The fifth driving member 43 is configured to drive the clamping block 42 to move along the second direction Y closer to or away from the tooling plate 51; that is, the reference frame 205 and the clamping block 42 act on the tooling carriage 50 on opposite sides along the second direction Y, thereby positioning and calibrating the tooling carriage 50 in the second direction Y.

[0092] In some implementation methods, please refer to Figure 3 The clamping mechanism 40 also includes a fifth guide rail 41, which is disposed on the first stand 101 along the second direction Y. The clamping block 42 slides with the fifth guide rail 41 to ensure the stability of the clamping block 42 moving along the second direction Y and to ensure the positional accuracy of the battery module during transportation and stacking.

[0093] In some implementations, such as Figure 7 As shown, the second fixed reference mechanism 30 includes a third upright 301, a third driving member 302, a movable plate 303, a support member 306, and a positioning wheel 307. The third driving member 302 is disposed on the third upright 301. The movable plate 303 is slidably connected to the third upright 301 along the first direction X, and is connected to the third driving member 302. The third driving member 302 is configured to drive the movable plate 303 to move along the first direction X. The support member 306 is disposed on the side of the movable plate 303 near the second limiting plate 53. The positioning wheel 307 is connected to the support member 306 and is configured to abut against the second limiting plate 53 along the first direction X. Thus, the positioning wheel 307 provides a positioning reference for the second limiting plate 53 in the first direction X.

[0094] In some embodiments, the second fixed reference mechanism 30 further includes a fourth drive element 308 and a positioning block 309, such as Figure 7 As shown; wherein, the fourth driving member 308 is connected to the third support frame 301; the positioning block 309 is connected to the fourth driving member 308, and the fourth driving member 308 is configured to drive the positioning block 309 to move along the first direction X, so that the positioning block 309 can move closer to or away from the tooling plate 51, thereby realizing the positioning calibration of the tooling plate 51 in the first direction X, and ensuring the positional accuracy of the battery module during transportation and stacking.

[0095] In some implementations, to ensure the stability of the moving plate 303, please refer to... Figure 7The third support frame 301 is provided with a fourth guide rail 304, which extends along the first direction X. The moving plate 303 is provided with a fourth slider 305, which slides in cooperation with the fourth guide rail 304, thereby ensuring the stability and balance of the moving plate 303 moving along the first direction X.

[0096] The working process of this utility model is as follows: Please refer to... Figures 1-7 After the tooling trolley 50 is loaded with the battery module 60, the AGV trolley moves to the bottom of the tooling trolley 50. The AGV trolley lifts the tooling plate 51 and drives the tooling trolley 50 to move to the lifting mechanism 10. Under the action of the guide wheel 113, the tooling trolley 50 moves between the first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b. The first driving member 109 drives the moving rod 111 to move along the first direction X through the connecting block 110, thereby driving the first top block 106 to move along the first direction X, so that the first top wheel 105 abuts against the first top surface 106a. At this time, the receiving plate 104 is in the lifting state. The AGV trolley descends and transfers the tooling plate 51 to the receiving plate 104. At this time, the tooling trolley 50 is supported by the receiving plate 104.

[0097] The second driving member 203 drives the second top block 204 to move along the first direction X, so that the second top wheel 2027 abuts against the third top surface 204a, and the reference frame 205 extends along the second direction Y and abuts against the first limiting plate 52 as a positioning reference in the second direction Y. The fifth driving member 43 drives the clamping block 42 to abut against the tooling plate 51 supported on the receiving plate 104 along the second direction Y, thereby realizing the positioning calibration in the second direction Y.

[0098] The third driving component 302 drives the moving plate 303 to move along the first direction X, and drives the positioning wheel 307 to abut against the second limiting plate 53 through the support component 306. The fourth driving component 308 further drives the positioning block 309 to act on the tooling plate 51 along the first direction X, thereby realizing the positioning calibration in the second direction Y.

[0099] After positioning and calibration, the AGV trolley rises to receive the tooling trolley 50. The first sub-lifting mechanism 10a, the second sub-lifting mechanism 10b, the first fixed reference mechanism 20, the second fixed reference mechanism 30, and the clamping mechanism 40 are reset, and the tooling trolley 50 is transferred from the AGV trolley to the next process.

[0100] In summary, this utility model embodiment provides a positioning device. By setting up a lifting mechanism 10, when the AGV trolley transporting the tooling trolley 50 moves between the first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b, the AGV trolley lowers its height. The first sub-lifting mechanism 10a and the second sub-lifting mechanism 10b can lift and support the tooling trolley 50 in the third direction Z, so that the tooling trolley 50 is in a suspended state. Then, the first fixed reference mechanism 20, together with the clamping mechanism 40, performs positioning correction on the tooling trolley 50 in the second direction Y, and the second fixed reference mechanism 30 performs positioning correction on the tooling trolley 50 in the first direction X, thereby completing the precise positioning of the tooling trolley 50 in multiple directions. This ensures the positional accuracy of the battery modules during transportation and stacking, improves production efficiency, and avoids problems such as misalignment and tilting between modules caused by inaccurate positioning. It also improves the regularity and consistency of the internal structure of the battery pack, thereby improving the overall performance and safety of the battery pack.
