Description

Technical Field

[0001] The utility model relates to a battery sheet transport device and an adsorption mechanism. Background Art

[0002] In the existing technology, the handling device usually uses components such as suction cups to absorb the battery cells and transfer the battery cells between different workstations. Some workstations are at the same height, so the handling operation can be completed by simply moving the battery cells horizontally; while there are height differences between some workstations, and in addition to horizontal movement, the battery cells also need to be transported in the up and down directions.

[0003] Most equipment typically features multiple sets of handling devices, each with a clear division of labor. Some are used to carry cells at the same height, while others are used to carry cells at different heights. However, this setup is inefficient and results in high costs and energy consumption. Furthermore, when there are height differences between workstations, components such as suction cups can easily crush cells when lowering them. During the lowering process, cells can also easily collide with the workstation below, causing damage. Therefore, preventing damage to the cells is a pressing issue. Utility Model Content

[0026] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments to make the advantages and features of the present invention easier for those skilled in the art to understand. Obviously, the embodiments described in this application are only part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0027] See also Figure 1 A cell adsorption mechanism shown includes an upper support 31 and an adsorption seat 32. The adsorption seat 32 is arranged below the upper support 31, and the adsorption seat 32 can be arranged to float up and down relative to the upper support 31. When the adsorption mechanism 3 is working, the entire adsorption mechanism 3 is driven to move up and down by driving the upper support 31 to move up and down, and the cell 10 located below is adsorbed by the adsorption seat 32. When the cell 10 is sucked, since the adsorption seat 32 can float up and down relative to the upper support 31, it can avoid hard contact between the adsorption seat 32 and the cell 10, thereby avoiding damage to the cell 10. Similarly, when the adsorbed cell 10 is placed downward, the up and down floating of the adsorption seat 32 can also avoid hard contact between the cell 10 and the work station below, thereby avoiding damage to the cell 10.

[0028] See also Figure 2 、 Figure 3 A battery cell transport device shown in the figure includes a transport frame 1, an adsorption member 21 and the above-mentioned adsorption mechanism 3, wherein the transport frame 1 can be arranged to move along a preset direction; the adsorption member 21 and the adsorption seat 32 are arranged on the transport frame 1 at intervals along the preset direction, the adsorption member 21 is fixedly arranged relative to the transport frame 1 in the up and down directions, and the upper support 31 can be arranged on the transport frame 1 to move up and down.

[0029] In some embodiments, multiple adsorption members 21 and adsorption mechanisms 3 are provided, and the handling device can utilize the adsorption members 21 and adsorption mechanisms 3 to simultaneously handle multiple battery cells 10. Specifically, when the loading and unloading stations are at the same height, the adsorption members 21 can be used for handling. When there is a height difference between the loading and unloading stations, the adsorption mechanisms 3 can not only complete the handling of the battery cells 10, but also prevent the battery cells 10 from being damaged during handling.

[0030] In some embodiments, one of the upper support 31 and the adsorption base 32 is provided with a guide member 33 extending in the vertical direction, and the other is provided with a guide hole, into which the guide member 33 is slidably inserted, allowing the adsorption base 32 to float up and down relative to the upper support 31. In this embodiment, the guide member 33 is provided on the adsorption base and extends upward from the upper portion of the adsorption base. The upper support 31 is provided with a guide hole, into which the guide member 33 is slidably inserted.

[0031] In this embodiment, the guide member 33 is provided with a first buffer member 341 and a second buffer member 342. The first buffer member 341 and the second buffer member 342 are spaced apart in the vertical direction and are located on opposite sides of the upper support 31 in the vertical direction. Specifically, a fixing member 36 is fixed to the upper portion of the guide member 33 to connect the upper support 31 and the adsorption seat 32 and prevent them from separating. The first buffer member 341 is located between the fixing member 36 and the upper support 31. When the adsorption seat 32 moves downward relative to the upper support 31, the first buffer member 341 acts as a buffer between the fixing member 36 and the upper support 31, absorbing the impact energy between the fixing member 36 and the upper support 31, thereby protecting the adsorption mechanism 3. When the adsorption seat 32 moves upward relative to the upper support 31, the second buffer member 342 prevents direct contact between the upper support 31 and the adsorption seat 32, thereby preventing damage to the adsorption mechanism.

[0032] In this embodiment, the first buffer member 341 and the second buffer member 342 are cushions made of elastic material. In other embodiments, the first buffer member 341 and the second buffer member 342 can also be made of other elastically deformable components.

[0033] In this embodiment, a limiter is provided on the upper support 31. Along the length extension direction of the guide member 33, the limiter is located between the first buffer member 341 and the upper support 31, or between the second buffer member 342 and the upper support 31. The limiter can limit the displacement of the adsorption seat 32 relative to the upper support 31. Figure 1 As shown, the upper and lower sides of the upper support 31 are each provided with a stopper, namely a first stopper 351 and a second stopper 352. The first stopper 351 is located between the first buffer 341 and the upper support 31, and the second stopper 352 is located between the second buffer 342 and the upper support 31. When the second buffer 342 and the second stopper 352 are in contact, a first spacing d1 is defined between the first buffer 341 and the first stopper 351 in the vertical direction, and the distance d1 by which the adsorption seat 32 can move downward relative to the upper support 31 is defined. When the first buffer 341 and the first stopper 351 are in contact, a second spacing d2 is defined between the second buffer 342 and the second stopper 352 in the vertical direction, and the distance d2 by which the adsorption seat 32 can move upward relative to the upper support 31 is defined.

[0034] In this embodiment, the adsorption seat 32 includes a connecting portion 321 and an adsorption portion 322. The connecting portion 321 is connected to the upper support 31 in a floating manner, and the adsorption portion 322 is fixed below the connecting portion 321. Figure 1 、 Figure 4As shown, the guide member 33 is fixed on the upper portion of the connecting portion 321 , and the second buffer member 342 and the second limiting member 352 are disposed between the upper support 31 and the connecting portion 321 .

[0035] In this embodiment, a sensor 41 for detecting whether the battery cell 10 is adsorbed is fixedly provided on the connecting portion 321, and the adsorption portion 322 is provided with an avoidance hole 323 running through in the up and down directions. The sensor 41 is located above the avoidance hole 323. By providing the avoidance hole 323, the normal operation of the detection function of the sensor 41 can be ensured without affecting the adsorption function.

[0036] In this embodiment, the projections of the upper support 31, the connecting portion 321 and the adsorption portion 322 on the horizontal plane are all rectangular. Four guide members 33 are provided on the upper part of the connecting portion 321, and the four guide members 33 are respectively provided at the four corners of the rectangle. The stability of the adsorption seat 32 floating up and down is ensured by providing four guide members 33. In this embodiment, four sensors 41 are fixed on the outer side of the connecting portion 321, and the four sensors 41 are also respectively provided at the four corners of the connecting portion 321. In addition to improving the detection accuracy, such a setting can also make a rough judgment on the status of the battery cell 10 through multi-point detection to prevent the battery cell 10 from being misaligned when being adsorbed. Specifically, see Figure 1 As shown, in this embodiment, the sensor 41 is fixed to the outer side of the connecting portion 321 by a fixing bracket 42 . The fixing bracket 42 is L-shaped and extends downward and then outward from the outer side of the connecting portion 321 .

[0037] In this embodiment, the adsorption member 21 is fixed on the transport rack 1. The adsorption member 21 is also provided with a sensor 41 for detecting whether the battery cell 10 is adsorbed, and an avoidance hole for facilitating detection by the sensor 41. The sensor 41 is located above the avoidance hole.

[0038] In this embodiment, the transport rack 1 is provided with a lifting mechanism 5 for driving the upper support 31 to move up and down. When retrieving materials, the lifting mechanism 5 drives the upper support 31 to move downward to the first designated position. Since the adsorption seat 32 can move up and down relative to the upper support 31, the adsorption seat 32 is not directly driven downward by the lifting mechanism 5, but moves downward under the action of its own gravity. Compared with being directly driven by the lifting mechanism 5, the impact force exerted by the adsorption seat 32 on the battery cell 10 is smaller, which can effectively avoid damaging the battery cell 10. At the same time, after the adsorption seat 32 contacts the battery cell 10, the adsorption seat 32 can move upward relative to the upper support 31. The adsorption seat 32 will not continuously exert a downward force on the battery cell 10, further reducing the damage caused to the battery cell 10.

[0039] In this embodiment, by adjusting the first designated position and the first distance d1, the force exerted by the adsorption seat 32 on the battery cell 10 can be controlled. In this embodiment, the lifting mechanism 5 is a cylinder. In other embodiments, the lifting mechanism 5 can be other mechanisms capable of driving the upper support 31 to move up and down.

[0040] In this embodiment, when the adsorption mechanism 3 is sucking the battery cell 10 downward, the first buffer member 341 can exert its buffering effect when the adsorption seat 32 moves downward, protecting the adsorption mechanism 3 itself and the battery cell 10. When the adsorption seat 32 contacts the battery cell 10 and moves upward relative to the upper support 31, the second buffer member 342 can exert its buffering effect.

[0041] In this embodiment, after the adsorption mechanism 3 has attracted the battery cell 10, the lifting mechanism 5 drives the upper support 31 upward, lifting the adsorption base 32 and the battery cell 10. At the moment when the upper support 31 lifts the adsorption base 32 upward, the first buffer member 341 provides a cushioning effect. After the adsorption base 32 is lifted upward, the battery cell 10 is transferred by moving the transport frame 1, and the sensor 41 detects the downward direction to determine whether the battery cell 10 is adsorbed.

[0042] When the battery cell 10 is transferred to the unloading station and lowered, the lifting mechanism 5 drives the upper support 31 to move downward to the second designated position. Similarly, the adsorption seat 32 with the battery cell 10 adsorbed thereon moves downward under the action of gravity until the battery cell 10 contacts the station below. Since the adsorption seat 32 can move upward relative to the upper support 31, it can avoid hard contact between the battery cell 10 and the station, thereby preventing damage to the battery cell 10. Similar to the process of sucking the battery cell 10, during the process of lowering the battery cell 10, the first buffer 341 and the second buffer 342 can also play a role in preventing damage to the battery cell 10 and the adsorption mechanism 3.

[0043] In this embodiment, a first station 101, a second station 102 and a third station 103 are sequentially arranged along a preset direction, wherein the first station 101 and the second station 102 are at the same height, and there is a height difference between the second station 102 and the third station 103. The adsorption member 21 is used to transport the battery cell 10 between the first station 101 and the second station 102, and the adsorption mechanism 3 is used to transport the battery cell 10 between the second station 102 and the third station 103.

[0044] In this embodiment, the cell transport device further includes a guide rail 6 and a drive member. The guide rail 6 extends in a predetermined direction, and the transport rack 1 is movably mounted on the guide rail 6. The drive member is configured to drive the transport rack 1 to move along the length of the guide rail 6. The guide rail 6 provides guidance for the movement of the transport rack 1, ensuring the accuracy of the movement of the transport rack 1 and thus ensuring that the cell 10 is accurately transported.

[0045] In this embodiment, the transport frame 1 extends along a predetermined direction and is equipped with two suction members 21 and two suction mechanisms 3. The transport frame 1 defines a virtual symmetry plane extending along the predetermined direction. The two suction members 21 are symmetrically arranged relative to the virtual symmetry plane, and the two suction mechanisms 3 are symmetrically arranged relative to the virtual symmetry plane. The transport device can simultaneously transport four battery cells 10, achieving higher transport efficiency. Furthermore, the suction members 21 and suction mechanisms 3 are symmetrically distributed on both sides of the transport frame 1, ensuring stability during transport.

[0046] In summary, the cell handling device of this embodiment is capable of simultaneously handling multiple cell wafers 10. The adsorption member 21 can be used to transport cell wafers 10 between the first and second stations 101, 102, which are of equal height. The adsorption mechanism 3 can be used to transport cell wafers 10 between the second and third stations 102, 103, which have a height difference. The adsorption base 32 of the adsorption mechanism 3 is capable of floating up and down relative to the upper support 31, thereby preventing damage to the cell wafers 10 when the cell wafers 10 are drawn down and lowered. A first buffer member 341 and a second buffer member 342 are provided on the upper and lower sides of the upper support 31, respectively, to protect the adsorption mechanism 3 during handling.
