[0037] The present application provides extensions at both ends of the first bracket, and the extensions are used to install a through-beam sensor group, so that the transmitting sensor and the receiving sensor of the through-beam sensor group are respectively located on the extensions at both ends of the first bracket, thereby increasing the distance between the transmitting sensor and the receiving sensor. Compared with traditional loading sensors, the sensing area between the transmitting sensor and the receiving sensor provided by the present application is larger. When the battery cell is driven by a transmission belt to pass through the sensing area, the probability of the transmitting sensor and the receiving sensor contacting the battery cell is reduced, thereby reducing the risk of the through-beam sensor group scratching the battery cell, thereby ensuring product quality.

[0038] Embodiment 1

[0039] like Figures 1 to 6 As shown, an embodiment of the present application provides a battery cell sensing device, comprising:

[0040] A first bracket 100;

[0041] Extension portions 200 disposed at both ends of the first bracket 100; and

[0042] The through-beam sensor set includes a transmitting sensor 310 and a receiving sensor 320 which are respectively disposed on the extension parts 200 at two ends of the first bracket 100 .

[0043] During implementation, the battery cell sensing device provided in the present application is used to sense and detect battery cells, such as detecting battery cell transportation, loading or unloading, etc., without limitation.

[0044] Optionally, the battery cells need to undergo corresponding process treatment in the automated production equipment, such as Figure 1 As shown, the automated production equipment includes an automated loading mechanism, an automated loading transmission, a main station 730, an automated unloading transmission and an automated unloading mechanism. The battery cells are placed in a cell basket, sent to the automated loading transmission to the main station 730 for process processing via the automated loading mechanism, and then sent to the automated unloading mechanism via the automated unloading transmission under the main station 730, completing the loading and unloading cycle before and after the battery cell process.

[0045] The cell sensing device provided in the present application can be set at the starting position of the automatic feeding and transmission. Since the first bracket 100 is provided with extension parts 200 at both ends, the transmitting sensor 310 and the receiving sensor 320 of the radiation type sensor group are respectively provided on the two extension parts 200, thereby increasing the distance between the transmitting sensor 310 and the receiving sensor 320, that is, increasing the sensing area. The cell passes through the sensing area under the action of the automatic feeding and transmission, and is detected, and then the cell is photographed by the subsequent camera to realize the corresponding function, such as cell surface detection, etc., without limitation.

[0046] In some possible embodiments, the extension portion 200 and the first bracket 100 are movably connected. For example, the extension portion 200 is connected to the first bracket 100 by screws or bolts. The relative position between the extension portion 200 and the first bracket 100 can be adjusted by tightening or loosening the screws or bolts, thereby adjusting the distance between the two extension portions 200. That is, the sensing area between the transmitting sensor 310 and the receiving sensor 320 can be adjusted.

[0047] As a possible implementation, the first bracket 100 and the extension part 200 may be formed in an integral structure. In other words, the extension part 200 is formed by extending from both ends of the first bracket 100. Since the distance between the two extension parts 200 is fixed, the sensing area between the transmitting sensor 310 and the receiving sensor 320 is also fixed. For example, the distance between the transmitting sensor 310 and the receiving sensor 320 may be set to 50 mm to 150 mm, for example, the distance between the transmitting sensor 310 and the receiving sensor 320 may be set to 80 mm, 100 mm or 110 mm, etc., so that the sensing area between the transmitting sensor 310 and the receiving sensor 320 does not scratch the battery cell when the battery cell passes by, without limitation.

[0048] In the present application, extension parts 200 are provided at both ends of the first bracket 100, and the extension parts 200 are used to install the through-beam sensor group, so that the transmitting sensor 310 and the receiving sensor 320 of the through-beam sensor group are respectively located on the extension parts 200 at both ends of the first bracket 100, thereby increasing the distance between the transmitting sensor 310 and the receiving sensor 320. Compared with traditional loading sensors, the sensing area between the transmitting sensor 310 and the receiving sensor 320 provided in the present application is larger. When the battery cell is driven by the transmission belt to pass through the sensing area, the probability of the transmitting sensor 310 and the receiving sensor 320 contacting the battery cell is reduced, thereby reducing the risk of the through-beam sensor group scratching the battery cell, thereby ensuring product quality.

[0049] In some optional embodiments, the battery cell sensing device provided in the present application further includes a second bracket 400 that is movably and adjustably connected to the first bracket 100 in the first direction.

[0050] In implementation, the second bracket 400 can be fixedly mounted on the frame 700 of the automated production equipment. Since the first bracket 100 can be movable and adjusted relative to the second bracket 400 in a first direction, the first direction is as follows: Figure 3 During installation, the relative position between the first bracket 100 and the second bracket 400 can be specifically adjusted according to the position of the automated loading and transmission of the automated production equipment to ensure that the battery sheet does not scrape the transmitting sensor 310 and the receiving sensor 320 when passing through the sensing area between the transmitting sensor 310 and the receiving sensor 320.

[0051] In some optional embodiments, the battery cell sensing device provided in the present application further includes a third bracket 500 that is movably and adjustably connected to the second bracket 400 in a second direction, and the second direction is perpendicular to the first direction.

[0052] During implementation, the second bracket 400 is fixedly mounted on the frame 700 of the automated production equipment through the third bracket 500. Since the first bracket 100 can be moved and adjusted in a first direction relative to the second bracket 400, and the second bracket 400 can be moved and adjusted in a second direction relative to the third bracket 500, the first direction and the second direction are as follows. Figure 3 During installation, since the first direction and the second direction are perpendicular to each other, the first bracket 100 can be adaptively adjusted within the plane where the X-axis and the Y-axis are located, and the adjustment is more convenient and reliable, and it is sufficient to ensure that the transmitting sensor 310 and the receiving sensor 320 do not scratch the battery sheet, without limitation.

[0053] In some optional embodiments, the battery cell sensing device provided in the present application further includes a fourth bracket 600 movably and adjustably connected to the third bracket 500 in a third direction; the third direction is perpendicular to both the second direction and the first direction.

[0054] During implementation, the third bracket 500 is fixedly mounted on the frame 700 of the automated production equipment through the fourth bracket 600. In other words, the first bracket 100, the second bracket 400, the third bracket 500 and the fourth bracket 600 are sequentially connected and fixedly mounted on the frame 700 of the automated production equipment. Since the first bracket 100 can be moved and adjusted in a first direction relative to the second bracket 400, the second bracket 400 can be moved and adjusted in a second direction relative to the third bracket 500, and the third bracket 500 can be moved and adjusted in a third direction relative to the fourth bracket 600, the first direction, the second direction and the third direction are perpendicular to each other. Figure 3 The X-axis, Y-axis and Z-axis are shown.

[0055] For example, the first direction is the up-down direction perpendicular to the horizontal plane, the second direction can be regarded as the left-right direction, and the third direction can be regarded as the front-back direction. During installation, since the first direction, the second direction and the third direction are mutually perpendicular, the first bracket 100 can be adaptively adjusted in the three-dimensional space, and the adjustment is more convenient and reliable, and it is sufficient to ensure that the transmitting sensor 310 and the receiving sensor 320 do not scratch the battery sheet, without limitation.

[0056] Optionally, the movable and adjustable connection between the brackets can be realized through a slotted hole. For example, the first bracket 100 is provided with a slotted hole 110, which extends along the first direction, and the second bracket 400 is provided with a threaded hole 410, which is connected with the threaded hole 410 by a bolt. When the bolt is tightened, the first bracket 100 and the second bracket 400 are fixedly connected, and the position between the first bracket 100 and the second bracket 400 is relatively fixed. When the bolt is loosened, the bolt can move in the slotted hole 110, that is, the first bracket 100 and the second bracket 400 can be relatively moved and adjusted, and when the bolt is tightened again, the first bracket 100 and the second bracket 400 are locked and connected again.

[0057] Similarly, the second bracket 400 and the third bracket 500, as well as the third bracket 500 and the fourth bracket 600, can also be connected by using slotted holes and bolts to achieve a movable and adjustable connection. For example, the third bracket 500 is provided with a slotted hole 510, which extends along the second direction, and the second bracket 400 is provided with a threaded hole 420, which is connected to the threaded hole 420 by bolts. The connection structure and implementation principle between the second bracket 400 and the third bracket 500, as well as between the third bracket 500 and the fourth bracket 600, please refer to the connection structure and implementation principle between the first bracket 100 and the second bracket 400, and no further description is given.

[0058] In other embodiments, two adjacent brackets may be connected in a movable and adjustable manner by other means, for example, a slide groove 610 is provided on the fourth bracket 600, the slide groove 610 extends along the third direction, and the third bracket 500 is provided with a threaded hole 520, and the slide groove 610 is connected with the threaded hole 520 by a bolt. When the bolt is tightened, the third bracket 500 and the fourth bracket 600 are fixedly connected, and the position between the third bracket 500 and the fourth bracket 600 is relatively fixed. When the bolt is loosened, the bolt can slide in the slide groove 610, that is, the third bracket 500 and the fourth bracket 600 can be relatively movable and adjusted, and when the bolt is tightened again, the third bracket 500 and the fourth bracket 600 are locked and connected again.

[0059] As a possible implementation, the first bracket 100, the second bracket 400, the third bracket 500 and the fourth bracket 600 can adopt an integrated structure, that is, an overall bracket consisting of the first bracket 100, the second bracket 400, the third bracket 500 and the fourth bracket 600 is made by an integrated forming process, which can effectively improve the structural strength of the overall bracket and improve product stability and reliability.

[0060] In some other possible embodiments, the second bracket 400, the third bracket 500 and the fourth bracket 600 may be designed as an integrated structure, so that the position of the first bracket 100 can be appropriately adjusted while ensuring structural strength and stability, which has wider applicability.

For example, the loading assembly 720 includes a loading rail provided between the cell placing assembly 710 and the main stage 730, and the carrier cooperates with the loading rail to transport the battery cells from the cell placing assembly 710 to the main stage 730, and the battery cell sensing device corresponds to the loading rail. In other words, when the loading assembly 720 transports the battery cells, it will pass through the sensing area of ​​the battery cell sensing device to realize the detection function of the battery cells.

[0070] Optionally, the host station 730 can be a PL camera, which is used to cooperate with the battery cell sensing device to take pictures of the battery cells. In other words, when the battery cell sensing device detects that a battery cell passes through the sensing area, it notifies the PL camera to take pictures, thereby improving the efficiency and accuracy of battery cell image acquisition.

[0071] In some optional embodiments, the cell detection mechanism provided by the present application further includes an image acquisition component (not shown) disposed on the transport channel for the feeding component 720 to transport the cell. In this case, the host station 730 refers to a device for performing specific process treatments on the cell (e.g., film lamination, spray coating, etc.). The image acquisition component is used to acquire images of the cell. For example, the image acquisition component can be a PL camera or a video camera, etc., which can cooperate with the cell sensing device to take pictures of the cell to obtain images of the cell for subsequent processes.
