DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Figure 1 This is a schematic diagram of the overall structure provided by an embodiment of the present utility model; Figure 2 The embodiment of the present utility model provides Figure 1 A schematic diagram of the enlarged structure at point A; Figure 3 This is a schematic diagram of the overall structure from another perspective provided by an embodiment of the utility model; Figure 4 The embodiment of the present utility model provides Figure 3 A schematic diagram of the enlarged structure at point B; Figure 5 This is a schematic top view of the overall structure provided by an embodiment of the utility model;

[0030] Figure 6 This is a bottom view schematic diagram of the overall structure provided by an embodiment of the utility model; Figure 7 The embodiment of the present utility model provides Figure 6 The enlarged structural diagram at C is shown in FIG. Figures 1 to 7 The CTP-compatible suction tool shown includes: a square frame 1, a first guide rail 2, an elliptical suction cup 3 and a vacuum bus 4. The first guide rail 2 is arranged along the length direction of the square frame 1. A plurality of elliptical suction cups 3 are provided and slidably arranged on the first guide rail 2. The elliptical suction cups 3 are located at the bottom of the square frame 1. The vacuum bus 4 is fixed on the square frame 1 and is connected to the plurality of elliptical suction cups 3.

[0031] For example, in an embodiment of the present invention, a battery module is formed by arranging multiple CTP cells, such as Figure 1 As shown, only the CTP cells at both ends of the battery module along the length direction are shown in the figure. Four lifting rings are provided above the square frame 1. The square frame 1 is lifted as a whole by the cooperation of the lifting equipment and the lifting rings. The square frame 1 is provided with a first guide rail 2 along the length direction. A plurality of elliptical suction cups 3 are slidably arranged in the first guide rail 2. The elliptical suction cups 3 are located below the first guide rail 2. The bottom of the elliptical suction cups 3 is in contact with the CTP cell, and the top of the elliptical suction cups 3 is connected to the vacuum bus 4. By activating the vacuum bus 4, the air between the elliptical suction cups 3 and the upper surface of the CTP cell is evacuated to a vacuum, so that the elliptical suction cups 3 can absorb and transport the CTP cell. Since the elliptical suction cup 3 is slidably disposed on the first guide rail 2, the positions of the multiple elliptical suction cups 3 on the first guide rail 2 can be adjusted so that the multiple elliptical suction cups 3 are suitable for the structure of the battery module composed of multiple CTP battery cells. The positions of the multiple elliptical suction cups 3 on the first guide rail 2 can be adjusted according to the thickness of the multiple CTP battery cells so that each elliptical suction cup 3 absorbs each CTP battery cell. The elliptical suction cup 3 is then fixed to the first guide rail 2 by bolts to prevent sliding during absorption and ensure the stability of the tooling. By providing the first guide rail 2, the spacing of the multiple elliptical suction cups 3 along the direction of the first guide rail 2 can be adjusted and fixed, thereby meeting the structural requirements of the battery module composed of different CTP battery cells.

[0032] The embodiment of the present utility model provides a CTP-compatible suction tooling, which sets up a first guide rail 2 on a square frame 1, connects a vacuum bus 4 with the suction cup 3, brings the elliptical suction cup 3 into contact with the upper surface of the CTP battery cell, and then draws a vacuum between the elliptical suction cup 3 and the CTP battery cell through the vacuum bus 4, so that the elliptical suction cup 3 is tightly connected to the upper surface of the CTP battery cell. By slidably mounting multiple elliptical suction cups 3 on the first guide rail 2, the multiple elliptical suction cups 3 can adjust the spacing of the multiple elliptical suction cups 3 along the direction of the first guide rail when sucking the CTP battery cell according to the different thicknesses of the multiple CTP battery cells, so as to adapt to different CTP battery cell structures, which can effectively solve the problem of low compatibility in the prior art.

[0033] Optionally, the first guide rail 2 is provided with a plurality of waist-shaped holes 21 along the length direction of the first guide rail 2 , the plurality of waist-shaped holes 21 are arranged along the width direction of the square frame 1 , and the plurality of elliptical suction cups 3 are slidably disposed in the waist-shaped holes 21 .

[0034] For example, in an embodiment of the present utility model, the elliptical suction cup 3 is installed on the first guide rail 2 through the waist-shaped hole 21, and a nut with a diameter larger than the width of the waist-shaped hole 21 is set at the upper end of the waist-shaped hole 21. The elliptical suction cup 3 is installed below the waist-shaped hole 21, so that the elliptical suction cup 3 can slide along the direction of the first guide rail 2. When the position of the elliptical suction cup 3 needs to be fixed, the fixation can be completed by tightening the nut. In this embodiment, two waist-shaped holes 21 are provided along the width direction of the square frame 1, and an elliptical suction cup 3 is provided in each waist-shaped hole 21, forming two rows of elliptical suction cups 3. When a CTP battery cell is sucked in, two elliptical suction cups 3 are used to suck a CTP battery cell at the same time, thereby improving the stability of the tooling in sucking the CTP battery cell. During the sucking and transportation process, when one of the elliptical suction cups 3 fails, the other elliptical suction cup 3 can still suck the CTP battery cell to prevent the CTP battery cell from falling and being damaged, thereby improving the stability of the tooling.

[0035] Optionally, a first scale bar 22 is provided on the first guide rail 2 , and the first scale bar 22 is arranged along the direction of the first guide rail 2 .

[0036] For example, in an embodiment of the present invention, by setting a first scale bar 22, before sucking the CTP battery cell, each elliptical suction cup 3 can be adjusted to a fixed position in advance according to the battery module structure to be assembled. Through the first scale bar 22, the distance between each elliptical suction cup 3 can be accurately read to correspond to the distance between each CTP battery cell, thereby improving the operational convenience of the tooling.

[0037] Optionally, a second guide rail 5 is provided along the width direction of the square frame 1 , and the first guide rail 2 is slidably provided on the second guide rail 5 .

[0038] For example, in an embodiment of the present utility model, two second guide rails 5 are provided, which are arranged in parallel and at intervals on the square frame 1, and the first guide rail 2 is mounted on the second guide rail 5 through a T-shaped block. By setting the second guide rail 5 and slidably setting the first guide rail 2 on the second guide rail 5, the position of the tooling along the width direction of the square frame 1 when absorbing the CTP battery cell can be adjusted. When the lifting equipment located above the square frame 1 is inconvenient to move along the width direction of the square frame 1, the position of the first guide rail 1 on the second guide rail 5 can be adjusted to facilitate the adaptation of the CTP battery cell, thereby further improving the operational convenience of the tooling.

[0039] Optionally, a plurality of first guide rails 2 are provided, and the intervals between the plurality of first guide rails 2 are adjustable.

[0040] For example, in an embodiment of the present invention, by providing multiple first guide rails 2, the tooling can adapt to the structural form of multiple rows of battery modules. In this embodiment, the structural form is a double-row battery module. The elliptical suction cup 3 on each first guide rail 2 can absorb a row of battery modules, so that the double-row battery modules can be sucked together for transportation and incorporated into the box. Accordingly, two vacuum busbars 4 are provided, and each elliptical suction cup 3 on the first guide rail 2 is connected to a corresponding vacuum busbar 4. Since the length of each CTP battery cell is different, the distance between the double-row battery modules can be adjusted by adjusting the position of the first guide rail 2 on the second guide rail 5, thereby adapting to CTP battery cells of different sizes, thereby further improving the compatibility of the tooling.

[0041] Optionally, a second scale bar 51 is provided on the second guide rail 5 , and the second scale bar 51 is arranged along the direction of the second guide rail 5 .

[0042] For example, in an embodiment of the present invention, by setting a second scale bar 51, before the CTP battery cell is sucked up, each first guide rail 2 can be adjusted to a fixed position in advance according to the multi-row battery module structure to be assembled. Through the second scale bar 51, the spacing between each first guide rail 2 can be accurately read to correspond to the spacing between each row of battery modules, thereby further improving the operational convenience of the tooling.

[0043] Optionally, large-surface pressing mechanisms 6 are provided at both ends of the square frame 1 along the length direction. The large-surface pressing mechanisms 6 include a movable plate 61 and a fixed plate 62 . The movable plate 61 and the fixed plate 62 are arranged in parallel and spaced apart, and the spacing between them is adjustable.

[0044] For example, in an embodiment of the present invention, the movable plate 61 and the fixed plate 62 are respectively arranged vertically at the two ends of the length direction of the battery module. After the elliptical suction cup 3 absorbs the upper edge of the CTP battery cell, it can move toward the fixed plate 62 through the movable plate 61, so that the battery module is subjected to clamping forces from both ends. When the battery module is transported, the large-surface clamping mechanism 6 can provide an anti-fall function during transportation. After the tooling transports the battery module to the top of the box, when the battery module is to be put into the box, the movable plate 61 can be continuously controlled to move toward the fixed plate 62 to compress the battery module so that the battery module is squeezed to a specified length, thereby facilitating the loading into the box. The operation of lowering the battery module into the box is then performed by aligning the box. The provision of the large-surface clamping mechanism 6 improves the safety of the tooling while further improving the ease of operation of the tooling.

[0045] Optionally, the square frame 1 is provided with a third scale bar 11 along the length direction, and the movable plate 61 is provided with a pointer 63 matching the third scale bar 11 .

[0046] For example, in an embodiment of the present invention, by setting a third scale bar 11 and a pointer 63, the distance between the movable plate 61 and the fixed plate 62 can be determined according to the reading, so that the battery module can be squeezed to the accurate length according to the length of the box known in advance, thereby further improving the operational convenience of the tooling.

[0047] Optionally, an anti-loosening mechanism 7 is also included, which includes a gear 71 and a pin 72. The large-surface clamping mechanism 6 also includes a threaded rod 64 and a handle 65. The threaded rod 64 is arranged along the length direction of the square frame 1, and the movable plate 61 is passed through the threaded rod 64. The handle 65 is arranged at one end of the threaded rod 64 close to the movable plate 61. The gear 71 is arranged on the threaded rod 64, and the pin 72 is configured to move toward the tooth surface of the gear 71.

[0048] For example, in the embodiment of the present invention, one end of the threaded rod 64 is mounted on the fixed plate 62 through a bearing, and the other end is mounted with the movable plate 61. By rotating the handle 65, the threaded rod 64 is driven to rotate, so that the movable plate 61 can move closer to or away from the fixed plate 62. The latch 72 is arranged perpendicular to the threaded rod 64. Figure 7 As shown, the anti-loosening mechanism 7 also includes a limiting protrusion 73 and a limiting groove 74. The limiting protrusion 73 is arranged perpendicular to the latch 72. In the initial state, the limiting protrusion 73 is perpendicular to the threaded rod 64, and the latch 72 cooperates with the gear 71 on the threaded rod 64 to limit the threaded rod 64, so that the threaded rod 64 cannot rotate, thereby making the distance between the movable plate 61 and the fixed plate 62 non-adjustable. When it is necessary to adjust the distance between the movable plate 61 and the fixed plate 62, the limiting protrusion 73 is pulled and rotated to move it into the limiting groove 74. At this time, the limiting protrusion 73 is parallel to the threaded rod 64, so that the latch 72 is disengaged from the gear 71, thereby allowing the threaded rod 64 to rotate to adjust the distance between the movable plate 61 and the fixed plate 62. By providing the anti-loosening mechanism 7, it is possible to prevent the large-surface pressing mechanism 6 from failing due to changes in the distance between the movable plate 61 and the fixed plate 62 during transportation, thereby further improving the stability of the tooling.

[0049] Optionally, a negative pressure monitoring meter 41 is provided on the vacuum bus 4 .

[0050] For example, in an embodiment of the present invention, the suction force of the vacuum bus 4 can be adjusted. By setting a negative pressure detection gauge 41, the air pressure in the vacuum bus 4 can be monitored, thereby monitoring the suction force of the elliptical suction cup 3 on the CTP battery cell. According to the battery modules of different sizes that need to be sucked, the suction force of the vacuum bus 4 can be adjusted to the required value through the value of the negative pressure detection gauge 41, thereby ensuring that the suction force of the elliptical suction cup 3 on the CTP battery cell is sufficient to suck it up, reducing the process of repeatedly adjusting the suction force of the vacuum bus 4, thereby further improving the operational convenience of the tooling.
