[0027] The detection mechanism includes an elastic telescopic part, and the two ends of the elastic telescopic part are respectively connected to a fixed part 4 and an abutment part 2. The bottom end surface of the fixed part 4 is fixedly arranged on the bottom end surface of the detection mechanism cavity. The two ends of the fixed part 4 are respectively connected to the lower end of the elastic telescopic part and the bottom end surface of the cavity. The fixed part 4 includes a circular or square structure. The top end surface of the fixed part 4 is a plane. The abutment part 2 is fixedly arranged on the top end of the elastic telescopic part. The top end surface of the abutment part 2 is a plane. The abutment part 2 is a circular or square structure.
[0028] In other embodiments, a detection module 401 is provided in the fixing portion 4. The detection module 401 is connected to the bottom end of the elastic expansion portion. The detection module 401 includes a pressure sensor, which detects the pressure of the elastic expansion portion on itself, and is connected to a data transmission line 402, and the pressure sensor sends the detected pressure data through the data transmission line 402.
[0029] In other embodiments, the fixing portion 4 is connected to a detection module 401, and the detection module 401 includes a height sensor, and the height sensor detects the height of the top end of the elastic telescopic portion. The height sensor is connected to a data transmission line 402, and the height sensor sends the detected height data through the data transmission line 402.
[0030] In other embodiments, the fixing part 4 is provided with a detection module 401, and the detection module 401 includes a distance sensor, and the distance sensor detects the height between the fixing part 4 and the abutting part 2. The distance sensor is connected to a data transmission line 402, and the distance sensor sends the detected distance data through the data transmission line 402.
[0031] In other embodiments, the fixing part 4 is provided with a detection module 401, the detection module 401 includes a power sensor, the current sensor is connected to a pressure sensor, the pressure sensor detects the pressure on the top end face of the fixing part 4, the pressure sensor sends different current signals according to the different pressures, and the current sensor detects different current sizes of the pressure sensor. The current sensor is connected to a data transmission line 402, and the current sensor sends the different currents detected through the data transmission line 402.
[0032] The elastic expansion part includes a spring 3, and the two ends of the spring 3 are respectively fixed to the fixed part 4 and the abutting part 2. When no detection is performed, the spring 3 is in a natural state. When the abutting part 2 is subjected to the pressure of the pole group slotting machine to be detected, the spring 3 is subjected to the pressure from the abutting part 2 and is compressed. When the spring 3 is compressed, the detection module 401 in the fixed part 4 detects the corresponding data as depth data.
[0033] like Figure 2As shown, the fixing portion 4 includes a bottom sheet structure, and the size of the bottom sheet structure is the same as the size of the bottom end face of the detection mechanism cavity. The outer edge of the bottom sheet structure abuts against the bottom of the side wall of the detection mechanism cavity. The bottom sheet structure is connected to a data transmission line 402, and the data transmission line 402 extends outward through the detection mechanism cavity. The abutting portion 2 is provided with a top sheet structure, and the size of the top sheet structure is smaller than the size of the bottom sheet structure. The thickness of the top sheet structure is greater than the thickness of the bottom sheet structure.
[0034] Symmetrically arranged pulleys 201 are provided on both sides of the top sheet-like structure. The pulleys 201 are rotatably provided on the sides of the top sheet-like structure, and are rollingly connected to the side walls of the cavity of the detection mechanism. The pulley 201 rolls on the side walls of the cavity of the detection mechanism. When the detection is performed, the abutment portion 2 is subjected to the pressure of the pole group slotting machine, so that the abutment portion 2 overcomes the elastic force of the elastic telescopic portion and moves downward, and the pulley 201 rolls downward along the side wall of the detection mechanism driven by the top sheet-like structure. At this time, since the top sheet-like structure moves linearly in the vertical direction, the pulley 201 also rolls vertically along the axial line of the side wall of the cavity of the detection mechanism.
[0035] like Figure 3 As shown, the elastic expansion member includes a spring 3, and fixing seats are provided at both ends of the spring 3. The spring 3 is connected to the abutment portion 2 and the fixing portion 4 through the fixing seats at both ends. The fixing seats are integrally formed with the spring 3. The fixing seats are fixedly connected to the abutment portion 2 and the fixing portion 4, respectively.
[0036] like Figure 3 As shown, the top sheet structure is in a square shape, and the left and right sides of the top sheet structure are connected to the pulley 201. The left and right sides of the top sheet structure are respectively provided with cylindrical connectors, and the cylindrical connectors are arranged vertically with the top sheet structure. The two cylindrical connectors are symmetrically arranged on the two sides of the top sheet structure. The cylindrical connector is connected with a U-shaped pulley 201 seat, and the protruding outer side of the U-shaped pulley 201 seat is connected to the end of the cylindrical connector, and the U-shaped pulley 201 seat is rotatably connected with the pulley 201. The U-shaped protrusion of the U-shaped pulley 201 seat faces the top sheet structure, and the U-shaped opening of the U-shaped pulley 201 seat faces the side wall of the detection mechanism. The pulley 201 is located in the U-shaped opening of the U-shaped pulley 201 seat, and a rotating shaft is provided in the U-shaped opening, and the rotating shaft is fixedly arranged in the U-shaped opening, and the rotating shaft passes through the pulley 201 and is rotatably connected with the pulley 201.
[0037] The pulley 201 rotates on the rotating shaft, and the rotating shaft passes through the central axis of the pulley 201. The pulley 201 is processed into a circular wheel-shaped structural member, and the rotating shaft passes through the center of the pulley 201. The two ends of the rotating shaft are respectively fixedly arranged on the corresponding two side surfaces of the U-shaped opening, and the U-shaped end of the U-shaped pulley 201 seat is provided with a fixing area, and the pulley 201 shaft is located in the shaft fixing area.
[0038] When in use, when the top sheet-like structure moves downward, the U-shaped sliding seat and the pulley 201 are driven to move downward through the cylindrical connecting piece. When the pulley 201 moves downward along the cavity of the detection mechanism, it rolls due to the friction between the edge of the pulley 201 and the inner wall of the cavity of the detection mechanism. The pulley 201 rotates with its center as the center. Since the rotating shafts of the pulley 201 are rotationally connected and the rotating shaft is fixedly set on the U-shaped pulley 201 seat, the pulley 201 rotates around the rotating shaft on the outer edge surface of the rotating shaft, and the rotating shaft does not rotate.
[0039] In other embodiments, cylindrical connectors are fixedly provided on the left and right sides of the top sheet-like structure, and the ends of the cylindrical connectors are threadedly or snap-fitted with the U-shaped pulley 201 seat. The cylindrical connectors penetrate the U-shaped protrusion of the U-shaped pulley 201 seat. The U-shaped pulley 201 seat is detachably mounted on the top sheet-like structure, and when the pulley 201 is worn after a long period of use, or when the pulley 201 is replaced as needed, it can be easily disassembled.
[0040] In other embodiments, a rotating shaft is rotatably connected in the U-shaped pulley 201 seat, and the rotating shaft is rotatably connected to the U-shaped end of the U-shaped pulley 201 seat. The rotating shaft is fixedly connected to the pulley 201. The pulley 201 is fixedly connected to the center of the rotating shaft. The center line of the pulley 201 coincides with the center line of the U-shaped pulley 201 seat. When the top sheet structure moves, it drives the cylindrical connecting member to move together, and the cylindrical connecting member drives the U-shaped pulley 201 seat to operate; when the U-shaped pulley 201 seat moves downward, it drives the rotating shaft to move along the vertical direction of the detection mechanism cavity, and at this time, the pulley 201 is also driven to move downward, and rolling occurs between the pulley 201 and the side wall of the detection mechanism cavity, causing the pulley 201 to rotate with its center as the axis at the same time; when the pulley 201 rotates, it drives the rotating shaft to rotate with its center line, so that the pulley 201 and the rotating shaft rotate synchronously, and the rotating shaft rotates in the U-shaped pulley 201 seat.
[0041] In other embodiments, Figure 5As shown, the fixing part 4 includes a square bottom sheet structure, and a detection module 401 is arranged on the upper surface of the bottom sheet structure, and the detection module 401 is fixedly arranged on the upper surface of the bottom sheet structure. The front side of the bottom sheet structure is connected to a data transmission line 402. The cross-sectional shape of the bottom sheet structure is a rectangle. At this time, the bottom end face shape of the detection mechanism cavity is a rectangle, and the housing 1 is a rectangular parallelepiped structure.
[0042] In other embodiments, the elastic telescopic part includes a pneumatic telescopic top rod, and when the abutment part 2 is squeezed by the pole group slotting machine, the pneumatic telescopic top rod is shortened; when the abutment part 2 is no longer squeezed by the pole group slotting machine, the pneumatic telescopic top rod is reset under the action of air pressure.
[0043] In other embodiments, the material of the housing 1 is a plastic compound.
[0044] In another embodiment, a device for detecting the depth of a pole group entering a slot includes one or more abutment parts 2 , one or more springs 3 , and one or more fixing parts 4 .
[0045] like Figure 2 As shown, a hole is opened on the side of each cell of the housing 1 of the battery model to be measured, the fixing part 4 is placed flat on the bottom of each cell with the detection module 401 facing upward, and the data transmission line 402 is extended along the hole on the side of the housing 1; the spring 3 is placed on the detection module 401, and the spring 3 presses the abutment part 2. The pulley 201 facilitates the abutment part 2 to move up and down in the cell.
[0046] The operation method is as follows: after the assembly is completed, the shell 1 is pushed into the slotting machine. When the slotting machine is pressed down, it touches the abutment part 2, and the abutment part 2 squeezes the spring 3 to deform. At the same time, the detection module 401 receives the pressure data and transmits it to the software through the data transmission line 402 to determine the height data corresponding to the maximum pressure to judge whether the slotting depth of each single grid is qualified.
[0047] For batteries of different models, it is only necessary to replace the corresponding housing 1 and the abutting portion 2 of the corresponding size.
[0048] In other embodiments, the fixing portion includes a top pressing plate.
[0049] These modifications or improvements made on the basis of the present invention without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
