Description

Technical Field

[0002] Lithium batteries are one of the most commonly used battery types in electric vehicles. Due to their high energy density and long cycle life, they have rapidly captured the vast majority of the electric vehicle battery market. Therefore, the performance of lithium batteries impacts the overall performance of electric vehicles. Most lithium battery shells are hollow, rectangular shells made from folded metal sheets and shaped like flat cuboids. The two sides of the shell are open for assembly of components such as the power supply core, tabs, and insulation. Excessive dimensional deviations at the shell opening can affect the assembly of the lithium battery and make it difficult to ensure the seal of the lithium battery. Therefore, dimensional inspection of the shell opening is a critical quality control step in the battery production process.

[0003] In the existing technology, manual inspection or laser inspection is usually used to inspect the square shell. Manual inspection is inefficient. Although laser inspection can quickly measure the actual size of the shell, laser inspection still has inconveniences, namely, workers are required to move and adjust the square shell, which is inconvenient to operate and can easily affect the accuracy of the inspection results due to human factors.

[0024] The present invention will be further described below with reference to the following embodiments and accompanying drawings.

[0025] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A square shell mouth detection device includes a detection platform 1, two detection frames 2 and a calibration block 12. The detection platform 1 is provided with two parallel and spaced linear guide rails 103, and the linear guide rails 103 extend along the length direction of the detection platform 1. A bottom plate 7 is provided below the detection frame 2, and the bottom plate 7 is slidably connected to the two linear guide rails 103 so that the detection frame 2 is slidably connected to the detection platform 1 along the length direction of the detection platform 1.

[0026] The inspection frame 2 is provided with two locking members 3, one located on either side of the base plate 7, and offset from the linear guide rail 103. The locking members 3 include an operating head 31 and an operating rod 32. The base plate 7 has an operating hole 701 through which the operating rod 32 is threaded. When a worker needs to lock the position of the inspection frame 2, they hold the operating head 31 and rotate it, screwing the operating rod 32 in. The end of the operating rod 32, away from the operating head 31, passes through the operating hole 701 and abuts against the inspection platform 1, thereby positioning the inspection frame 2.

[0027] The two detection racks 2 are provided with support platforms 4 on opposite sides for the square shell 14 to be placed horizontally. The support platforms 4 are provided with L-shaped side structures 402. The two side structures 402 are arranged opposite to each other, and the inner side walls of the side structures 402 are for the corners of the square shell 14 to abut.

[0028] Three size detection units 8 are slidably connected to the detection frame 2. The size detection units 8 include a mounting plate 81 and two detection beam sensors 82 arranged vertically and oppositely. The detection frame 2 is provided with two guide rods 5 arranged vertically and spaced apart. The guide rods 5 extend along the width of the detection platform 1. The mounting plate 81 is provided with a guide sleeve 9 slidably connected to the guide rods 5, so that the mounting plate 81 is slidably connected to the detection frame 2. The sliding direction of the mounting plate 81 is perpendicular to the sliding direction of the detection frame 2. The detection frame 2 is provided with two protective covers 13 arranged vertically and spaced apart. The openings of the two protective covers 13 are arranged opposite each other. The protective covers 13 are used to protect the detection beam sensors 82.

[0029] The support platform 4 is positioned between the two corresponding detection beam sensors 82. A clearance slot 401 extends through the support platform 4 along its length, allowing for clearance between the detection ends of the two corresponding detection beam sensors 82. The calibration block 12 is a standard component used for precision calibration. After adjusting the spacing between the two detection frames 2, the calibration block 12 can be placed on the two support platforms 4, with the end face of the calibration block 12 resting against the inner sidewall of the side structure 402, to perform a simulated test, achieve precision calibration, and avoid deviations in test results.

[0030] The detection beam sensors 82 are optical sensors. Preferably, the light sensor can be a laser sensor or an infrared sensor. Laser sensors and infrared sensors are conventional technology and are not described in detail here. The two detection beam sensors 82 are used to detect the outline dimensions of the square shell 14 placed on the support platform 4. When the light beam from the transmitting end of the light sensor is blocked by an object, the receiving end of the corresponding light sensor calculates the object size based on the number and position of the blocked light beams. A controller 101 and a display 102 are provided on the inspection platform 1. The detection beam sensors 82 and the display 102 are both electrically connected to the controller 101.

[0031] When using the detection device, the staff can adjust the distance between the two detection frames 2 according to the size specifications of the square shell 14 to be detected so that the two support platforms 4 can adapt to square shells 14 of different lengths. After the position of the detection frame 2 is adjusted, the detection frame 2 is positioned by the locking piece 3, and the two sides of the square shell 14 are respectively placed on the top surface of the two support platforms 4. By adjusting the distance between the two size detection units 8 to adapt to the square shell 14 to be detected, each detection shooting sensor 82 of the detection unit performs contour size detection on the mouth of the square shell 14 on the avoidance groove 401, and the measured value of the detection unit is displayed in real time by the display 102 controlled by the controller 101. The operation of the detection device is relatively flexible and has good applicability. During the detection process, only the size detection unit 8 needs to be moved to adapt to square shells 14 of different sizes and specifications. There is no need to manually adjust the position of the square shell 14, thereby ensuring the accuracy of the detection structure.

[0032] Preferably, two travel plates 6 are arranged in an upper and lower intervals on the outer side wall of the detection frame 2. The travel plates 6 extend along the width direction of the detection platform 1. The travel plate 6 is penetrated by a travel groove 601 extending along its length direction. The mounting plate 81 is threadedly connected to the side wall near the travel plate 6 with a fastener 10. The fastener 10 is a bolt structure. The fastener 10 is slidably connected in the travel groove 601. The fastener 10 is used to lock the mounting plate 81 on the travel plate 6, so that the mounting plate 81 slides to a predetermined position along the length direction of the travel plate 6 and is locked on the travel plate 6.

[0033] The staff can adjust the distance between two adjacent size detection units 8 on the detection frame 2. After the position of the size detection unit 8 is adjusted, the fastener 10 is rotated so that the rod of the fastener 10 is screwed into the corresponding mounting plate 81, and the head of the fastener 10 is pressed against the corresponding stroke plate 6 so that the mounting plate 81 slides along the length direction of the stroke plate 6, and the mounting plate 81 is locked on the stroke plate 6, so that the detection device has better flexibility in use.

[0034] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
