FCT testing equipment primarily performs functional tests on battery cells, such as voltage, current, power, and frequency. FCT test fixtures can test both semi-finished and finished products.
[0003] However, some existing FCT equipment can cause the battery cell to tilt when clamped, no longer in a vertical position. This prevents the cell from fitting into the fixture, potentially damaging it and causing combustion. This compromises operational safety and stability. Utility Model Content

[0007] Preferably, the angle α between the battery cell body and the corresponding vertical plane satisfies: α≤5°; the battery cell body and the sensing channel are staggered.
[0008] Preferably, the sensing mechanism includes a sensor component and at least two fixed components; the sensor component includes an inductive transmitter and an inductive receiver; the inductive transmitter is connected to one of the fixed components; the inductive receiver is connected to the other fixed component; and the inductive channel is formed between the inductive transmitter and the inductive receiver.
[0009] Preferably, the fixing assembly includes a fixing bracket and at least two fixing rods; one end of each of the fixing rods is movably connected to the fixing bracket; and the sensor assembly is connected to the other end of the corresponding fixing rod.
[0010] Preferably, the fixing assembly further comprises a connecting block; one end of the connecting block is slidably connected to the fixing bracket; and the other end of the connecting block is fixedly connected to the corresponding fixing rod.

[0014] Preferably, the clamper is a clamping cylinder.
[0015] The utility model also discloses an FCT device, comprising the battery core detection device.
[0016] The beneficial effect of the present utility model is that when the clamped battery cell body is offset during use of the present technical solution and enters the induction area where the induction channel and the assembly gap coincide, the induction signal of the induction mechanism will change; this indicates that the battery cell body is skewed, and thus the battery cell body needs to be corrected so that the battery cell body moves in a relatively appropriate placement direction, thereby ensuring the stability of the clamping and conveying of the battery cell body, and avoiding damage to the battery cell body and combustion caused by external force; thereby improving the safety and stability of the operation.

[0030] The following is combined with Figures 1 to 6 The present invention is further described in detail, but is not intended to limit the present invention.
[0031] like Figure 1 and 2 As shown, in one embodiment of the present utility model, the battery cell detection device includes a clamping mechanism 2 and a sensing mechanism 1; the clamping mechanism 2 includes a mounting assembly 21 and at least two clamps 22 connected to the mounting assembly 21; each of the clamps 22 is used to clamp the corresponding battery cell body 3 so that an assembly gap 201 is formed between two adjacent battery cell bodies 3; a sensing channel 120 is provided in the sensing mechanism 1; the sensing channel 120 and the assembly gap 201 are at least partially overlapped.
[0032] According to the technical solution of the present invention, when the clamped battery cell body is offset during use and enters the induction area where the induction channel and the assembly gap coincide, the induction signal of the induction mechanism will change; this indicates that the battery cell body is skewed, and thus the battery cell body needs to be corrected so that the battery cell body moves in a relatively appropriate placement (vertically downward) direction, thereby ensuring the stability of the clamping and conveying of the battery cell body, and avoiding damage to the battery cell body and combustion caused by external force, thereby improving the safety and stability of the operation.
[0033] Specifically, in some embodiments, Figure 1 As shown, the mounting assembly 21 includes a lifting drive component 211 and a mounting bracket 212; the lifting drive component 211 is driven and connected to the mounting bracket 212; and all the clamps 22 are connected to the mounting bracket 212. This structure can realize the convenience of the movement and clamping of the clamp 22 through the lifting drive component 211, so as to achieve convenient and rapid operation. Figure 2As shown, the lifting drive component 211 includes a support plate 213 and a lifting drive 214. The mounting end of the lifting drive 214 is connected to the support plate 213. The driving end of the lifting drive 214 is drivingly connected to the mounting bracket 212. Furthermore, the lifting drive 214 can be a power source formed by a lifting drive cylinder or a lifting drive screw.
[0034] In some embodiments, the clamp 22 may be a clamping cylinder; further, a clamping jaw of model HFR10, HFR16, HFR20, or HFR25 may be selected. This structure can ensure the stability of the clamping and improve the safety and stability of the operation.
[0035] Specifically, in some embodiments, Figure 1 As shown, the battery cell detection device further includes a bottom clamp 4 ; the bottom clamp 4 includes at least two clamps 41 ; a limiting cavity 42 is provided between two adjacent clamps 41 ; the limiting cavity 42 is provided below the clamp 22 .
[0036] Specifically, in some embodiments, Figure 1 As shown, the angle α between the cell body 3 and the corresponding vertical surface; when α satisfies: α≤5°, the cell body 3 and the sensing channel 120 are offset. In other words, when the tilt angle of the cell body 3 is less than or equal to 5°, it indicates that the cell body is partially offset, but it does not affect its ability to be clamped to other equipment below. It can also prevent the cell body from being damaged and burning due to external forces, thereby improving the safety and stability of operation. If the tilt angle of the cell body 3 exceeds 5°, if it is not discovered and corrected in time, the cell body 3 will not be able to enter the fixture, causing the cell body 3 to be damaged by external forces and burn.
[0037] Specifically, in some embodiments, Figure 1 and 2 As shown, the sensing mechanism 1 includes a sensor component 12 and at least two fixed components 11; the sensor component 12 includes a sensing transmitter 121 and a sensing receiver 122; the sensing transmitter 121 is connected to one of the fixed components 11; the sensing receiver 122 is connected to the other fixed component 11; and the sensing channel 120 is formed between the sensing transmitter 121 and the sensing receiver 122. Figure 2As shown, the inductive transmitter 121 and the inductive receiver 122 are respectively located on the left and right oblique sides of the clamp 22, i.e., they are projected and staggered. That is, the inductive transmitter 121 and the inductive receiver 122 are respectively installed in the front and rear rows to detect whether the distance between two adjacent sensor fixing rods of the battery cell body 3, the distance between two adjacent clamping plates, and the distance between two adjacent battery cell bodies 3 are the same. This structure can achieve the following: when the overhead travelling vehicle clamps the battery cell body 3, a normal battery cell body 3 is vertically downward and will not block the inductive channel 120 between the inductive transmitter 121 and the inductive receiver 122; a battery cell body 3 that is excessively tilted will block the inductive channel 120 between the inductive transmitter 121 and the inductive receiver 122, triggering an alarm and shutting down the equipment. The equipment can only continue to operate after the battery cell body 3 is straightened. Among them, the sensing transmitter 121 can be a photoelectric transmitter; the sensing receiver 122 can be a photoelectric sensing receiver; further, the sensing transmitter 121 can be a transmitter of a visible light sensor or a transmitter of an ultraviolet sensor; the sensing receiver 122 can be a receiver of a visible light sensor or a receiver of an ultraviolet sensor.
[0038] Specifically, in some embodiments, Figure 2 and 3 As shown, the fixing assembly 11 includes a fixing bracket 111 and at least two fixing rods 112; one end of each fixing rod 112 is connected to the fixing bracket 111; the sensor assembly 12 (the middle sensing transmitter 121 or the sensing receiver 122) is connected to the other end of the corresponding fixing rod 112. This structure allows each sensor assembly 12 (the middle sensing transmitter 121 or the sensing receiver 122) to be independently assembled to a separate fixing rod 112, thereby reducing detection interference between the individual sensor assemblies 12 (the middle sensing transmitter 121 or the sensing receiver 122) and improving the convenience of assembly and disassembly.
[0039] Specifically, in some embodiments, Figure 3 and 4 As shown, the fixing assembly 11 further includes a connecting block 113; one end of the connecting block 113 is slidably connected to the fixing bracket 111; the other end of the connecting block 113 is fixedly connected to the corresponding fixing rod 112. In other words, the fixing rod 112 can move left and right along with the overhead crane, but cannot move up and down, so as to achieve a wide range of detection and improve the convenience of operation. In other words, the connecting block 113 can be manually pushed to enable the fixing rod 112 to move left and right along with the overhead crane; or, the connecting block 113 can be connected to a driving cylinder or a driving screw to achieve electric pushing to enable the fixing rod 112 to move left and right along with the overhead crane.
[0040] Among them, Figure 4 and 5 As shown, the fixing bracket 111 is provided with at least one first mounting groove 114; one side end of the connecting block 113 is provided with a corresponding first slider; the first slider is movably connected to the inside of the first mounting groove 114; so that the fixing rod 112 can move left and right with the overhead travelling crane. Figure 4 and 6 As shown, the other side end of the connecting block 113 is provided with a limiting protrusion 115; the interior of the fixing rod 112 is provided with a second mounting groove 118 corresponding to the limiting protrusion 115; the limiting protrusion 115 is limitedly connected to the inner wall of the second mounting groove 118; so as to achieve the assembly stability between the connecting block 113 and the fixing rod 112. Figures 4 to 6 As shown, the connecting block 113 is provided with a limiting rod 116; the fixing bracket 111 is provided with at least one first mounting hole 117 corresponding to the limiting rod 116; and the fixing rod 112 is provided with at least one second mounting hole 119 corresponding to the limiting rod 116. In other words, the limiting rod 116 passes through the second mounting hole 119, the thickness of the connecting block 113, and the first mounting hole 117, respectively, to achieve a fixed connection between the connecting block 113 and the fixing rod 112, and a detachable connection between the connecting block 113 and the fixing bracket 111.
