Description

Technical Field

[0001] The utility model belongs to the technical field of diaphragm winding, and particularly relates to a winding machine for improving the utilization rate of a single roll of diaphragm. Background Art

[0002] In the actual production process, the fixed loss of the utilization rate of the diaphragm, which is a battery production auxiliary material, is relatively high. During the winding production process, after the warning glue sensor uses a color mark to detect the warning glue, for the next single roll of EA diaphragm, the single roll length is the length of 1 EA battery cell. During the process of changing the roll when the diaphragm is used up, after the defective product mark sensor recognizes and detects the splicing glue, for the next single roll of EA diaphragm, the single roll length is the length of 1 EA battery cell. There is a color mark sensing missed killing rate of about 0.4% in both steps. At the same time, when an employee finds that the diaphragm is drawn, a single roll of diaphragm needs to be executed, and the single roll length is the length of 1 EA battery cell. The single roll waste discharge of the diaphragm is in units of EA length. Taking the length of a 280 Ah electrode as an example, it is about 17 m.

[0003] In the current related technologies, in order to ensure the safety of the battery cell, when the diaphragm is abnormal, the color mark sensor recognizes the warning glue and the defective product mark. After successful recognition, the next single roll program of the EA diaphragm is executed, and the single roll length is 1 EA length. In fact, the position where the diaphragm is abnormal is in the middle of the diaphragm, far less than 1 EA length, resulting in excessive waste of the diaphragm. Summary of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a winding machine for improving the utilization rate of a single roll of diaphragm.

[0005] To achieve the above purpose, the utility model provides a winding machine for improving the utilization rate of a single roll of diaphragm, including a base. The upper surface of the base is fixedly connected with a fixing plate. One side of the fixing plate is rotatably connected with a feeding roller and a winding roller. One side of the fixing plate is rotatably connected with a plurality of guide rollers. The diaphragm on the feeding roller bypasses the guide rollers and winds around the winding roller. Warning glue and defective product marks are arranged at the wrinkled and damaged parts of the diaphragm. There are two mounting parts on one side of the fixing plate, and a first sensor and a second sensor are respectively mounted on the mounting parts. The first sensor is used to recognize the warning glue, and the second sensor is used to recognize the defective product mark.

[0006] Further, both the first sensor and the second sensor are CCD vision AI sensors.

[0007] Further, the mounting part includes two support rods. The two support rods are fixedly connected with the fixing plate. A sliding seat is slidably connected between the two support rods. A fixing frame is fixedly connected between the two sliding seats. The first sensor and the second sensor are located on the fixing frame.

[0008] Further, a fixed block is fixedly connected to the bottom surface of the fixed frame, a threaded rod is threadedly connected to the fixed block, and the threaded rod is rotatably connected to the fixed plate.

[0009] Further, two sliding blocks are slidably connected inside the fixed frame, one side of the sliding block is fixedly connected to a mounting plate, and the first sensor and the second sensor are fixed to one side of the mounting plate.

[0010] Further, a round rod is fixedly connected to the inner wall of the fixed frame, the round rod penetrates through the two sliding blocks and is slidably connected to the sliding blocks, a rotating rod is rotatably connected to the fixed frame, two sets of opposite threads are provided on the rotating rod, and the rotating rod penetrates through the sliding blocks and is threadedly connected to the sliding blocks.

[0011] The winding machine for improving the single-roll utilization rate of the diaphragm proposed by the present utility model can bring the following

[0012] Beneficial effects:

[0013] First, by setting the first sensor and the second sensor, after the first sensor detects the warning glue, the single-roll program is executed for the next EA diaphragm after the current double-roll is completed. After the second sensor identifies and detects the defective label, the current single-roll diaphragm continues to be single-rolled for 6 m until the distance to the second sensor is 4 m, and the redundant protection distance is 2 m, with a total of 6 m. Subsequently, the single-roll diaphragm is discharged as waste. In this solution, the process single-roll length is shortened from approximately 17 m of 1 EA length to approximately 6 m, reducing the waste of the diaphragm during the single-roll process to improve the single-roll utilization rate of the diaphragm.

[0014] Second, by setting the mounting parts, rotating the threaded rod, the threaded rod drives the sliding seat to slide, so that the first sensor and the second sensor slide on the support rod along with the two sliding seats, facilitating the adjustment of the positions of the first sensor and the second sensor. Rotating the rotating rod, the rotating rod drives the sliding blocks to move in opposite directions inside the fixed frame through two sets of opposite threads, adjusting the distance between the first sensor and the second sensor. Compared with the existing method of fixing by screws, this method is more flexible in adjusting the positions of the first sensor and the second sensor, and is convenient to adjust the first sensor and the second sensor to the optimal position according to the actual situation, improving the recognition effect of the warning glue defective label.

Specific embodiments

[0024] In order to more clearly illustrate the overall concept of the present utility model, the following will be described in detail by way of examples in conjunction with the drawings in the specification.

[0025] As Figures 1 to 6 shown, an embodiment of the present utility model provides a winding machine for improving the utilization rate of single-roll diaphragm, including a base 1, the upper surface of the base 1 is fixedly connected with a fixed plate 2, one side of the fixed plate 2 is rotatably connected with a feeding roller 3 and a winding roller 4, one side of the fixed plate 2 is rotatably connected with a plurality of guide rollers 5, the diaphragm 6 on the feeding roller 3 bypasses the guide rollers 5 and winds around the winding roller 4, warning glue 7 and defective product label 8 are arranged at the wrinkled and damaged parts of the diaphragm 6, two installation parts 9 are arranged on one side of the fixed plate 2, the first sensor 10 and the second sensor 11 are respectively installed on the installation parts 9, the first sensor 10 is used to identify the warning glue 7, the second sensor 11 is used to identify the defective product label 8, the diaphragm 6 is put in from the feeding roller 3, the diaphragm 6 is sent into the winding roller 4 along the guide rollers 5 and starts to wind, after the first sensor 10 detects the warning glue 7, after completing the current double-roll, the next EA diaphragm 6 executes the single-roll program, after the second sensor 11 identifies and detects the defective product label 8, the current single-roll diaphragm 6 continues to wind for 6 m, the distance to the second sensor 11 is 4 m, as Figure 6 shown at C in, the redundant protection distance is 2 m, with a total of 6 m, and then the single-roll diaphragm 6 is discharged as waste. The process single-roll length of this solution is shortened from about 17 m of 1 EA length to about 6 m, as Figure 5The length of the middle 11EA is 17m, which reduces the waste of the diaphragm 6 during the single-roll process and improves the single-roll utilization rate of the diaphragm 6.

[0026] Furthermore, as Figure 1 shown, both the first sensor 10 and the second sensor 11 are CCD vision AI sensors. In this solution, the CCD vision AI sensors are used to replace the existing color mark sensors to identify the warning glue 7 and defective product marks 8. Since the color mark sensor judges whether it is within the set threshold by detecting the optical signal reflected by the diaphragm 6, the color mark sensor is somewhat sensitive to environmental factors such as light, temperature, and humidity. However, environmental factors will have a certain impact on the measurement accuracy of the sensor, and there is a risk of about 0.4% of missed killings. By replacing it with a CCD vision AI sensor, the measurement accuracy can be improved and the risk of missed killings can be greatly reduced.

[0027] Furthermore, as Figure 1 and Figure 2 shown, the mounting member 9 includes two support rods 91. The two support rods 91 are fixedly connected to the fixed plate 2. A sliding seat 92 is slidably connected to the two support rods 91. A fixed frame 93 is fixedly connected between the two sliding seats 92. The first sensor 10 and the second sensor 11 are located on the fixed frame 93. A fixed block 16 is fixedly connected to the bottom surface of the fixed frame 93. A threaded rod 17 is threadedly connected to the fixed block 16. The threaded rod 17 is rotatably connected to the fixed plate 2. During use, the threaded rod 17 can be rotated, and the threaded rod 17 drives the sliding seat 92 to slide, so that the first sensor 10 and the second sensor 11 slide on the support rods 91 along with the two sliding seats 92, which is convenient for adjusting the positions of the first sensor 10 and the second sensor 11, so that the detection areas of the first sensor 10 and the second sensor 11 cover the surface of the diaphragm 6 passing through below. During adjustment, it is not necessary to disassemble the first sensor 10 and the second sensor 11. At the same time, compared with the existing fixed mounting frame, this method is more flexible to use.

[0028] Furthermore, as Figure 2 and Figure 3 shown, two sliding blocks 12 are slidably connected in the fixed frame 93. One side of the sliding block 12 is fixedly connected to a mounting plate 13. The first sensor 10 and the second sensor 11 are fixed on one side of the mounting plate 13. A round rod 14 is fixedly connected to the inner wall of the fixed frame 93. The round rod 14 passes through the two sliding blocks 12 and is slidably connected to the sliding blocks 12. A rotating rod 15 is rotatably connected to the fixed frame 93. Two sets of opposite threads are provided on the rotating rod 15. The rotating rod 15 passes through the sliding blocks 12 and is threadedly connected to the sliding blocks 12. During use, the rotating rod 15 can be rotated. The rotating rod 15 drives the sliding blocks 12 to move in opposite directions in the fixed frame 93 through the two sets of opposite threads to adjust the distance between the first sensor 10 and the second sensor 11. During use, the distance between the first sensor 10 and the second sensor 11 is controlled at 20 cm, as Figure 5 andFigure 6 In this case, A is 20 cm, which makes it more convenient to adjust the distance between the first sensor 10 and the second sensor 11.

[0029] Working principle: The first sensor 10 and the second sensor 11 are located on the fixed frame 93. By rotating the threaded rod 17, the threaded rod 17 drives the sliding seat 92 to slide, so that the first sensor 10 and the second sensor 11 slide on the support rod 91 along with the two sliding seats 92, which is convenient for adjusting the positions of the first sensor 10 and the second sensor 11, making the detection areas of the first sensor 10 and the second sensor 11 cover the surface of the diaphragm 6 passing through below. Rotate the rotating rod 15, and the rotating rod 15 drives the sliding block 12 to move in opposite directions within the fixed frame 93 through two sets of opposite threads, adjusting the distance between the first sensor 10 and the second sensor 11. When in use, the distance between the first sensor 10 and the second sensor 11 is controlled at 20 cm. The feeding roller 3 is placed with the diaphragm 6, and the diaphragm 6 is sent to the winding roller 4 along the guide roller 5 to start winding. After the first sensor 10 detects the warning glue 7, after the current double winding is completed, the next EA diaphragm 6 executes the single winding program. After the second sensor 11 identifies and detects the defective label 8, the current single-wound diaphragm 6 continues to be single-wound for 6 m until the distance between the defective label 8 and the CCD sensor is 4 m, and the redundant protection distance is 2 m, with a total of 6 m. Subsequently, the single-wound diaphragm 6 is discharged as waste.
