Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery diaphragm detection, in particular to a lithium battery diaphragm detection machine. Background Art

[0002] In the structure of lithium batteries, the diaphragm is one of the key internal components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, and directly affects the battery's capacity, cycle and safety performance. A diaphragm with excellent performance plays an important role in improving the overall performance of the battery. The main function of the diaphragm is to separate the positive and negative electrodes of the battery to prevent the two electrodes from contacting and short-circuiting. In addition, it also has the function of allowing electrolyte ions to pass through.

[0003] At present, lithium battery diaphragm detection machines are commonly used on the market to detect diaphragms. The lithium battery diaphragm detection machine includes a linear array camera structure and a light source structure. The linear array camera is used to capture images of lithium battery diaphragms passing through rollers, and the light source structure is used to provide light for the linear array camera when shooting. The position of the linear array camera of the existing lithium battery diaphragm detection machine is fixed. When there is a certain small-angle offset deviation in the transmission of the lithium battery diaphragm, the existing linear array camera cannot be rotated and adjusted at a corresponding small angle, which affects the normal shooting of the image and thus affects the accuracy of the detection. In order to enable the linear array camera to be rotated and adjusted at a small angle, the existing Chinese patent document CN202111137171.5 discloses a lithium battery diaphragm detection machine, including a frame, a camera structure including a linear array camera, a light source structure including a light source, and an encoder structure. The camera structure is arranged near the upper part of the frame, the light source structure is arranged near the lower part of the frame, and the encoder structure is arranged near the front end of the frame, so that the linear array camera can be rotated and adjusted at a small angle to ensure the normal shooting of the linear array camera.

[0004] In the above scheme, although the linear array camera of the inspection machine has the function of small-angle rotation adjustment, in order to realize this function, multiple rotating shafts need to be designed. In the actual process of adjusting the angle, the operator needs to manually rotate these rotating shafts, which not only increases the complexity of the operation, but also has relatively low adjustment efficiency. In addition, large errors are easily generated during the manual adjustment process, which affects the accuracy of the detection results. Therefore, this adjustment method has certain limitations in practical applications and cannot meet the needs of efficient and accurate detection. Summary of the invention

[0030] An oil box 11 is fixed on the top of the hood 9, and a maintenance mechanism 7 for lubricating the angle adjustment mechanism 5 is provided between the oil box 11 and the synchronization mechanism 6, so that when adjusting the angle of the linear array camera 4, the angle adjustment mechanism 5 can be lubricated with oil at the same time, which makes the use of the angle adjustment mechanism 5 more flexible and convenient, and can increase the service life of the angle adjustment mechanism 5;

[0031] A dust removal mechanism 8 is installed at the bottom of the fixing plate 3 , and the dust removal mechanism 8 is used to clean dust on the lens surface of the line array camera 4 .

[0032] For further information, see Figure 2-Figure 4 The angle adjustment mechanism 5 includes a first gear 501, a second gear 502, a first shaft 503, a second shaft 504 and an arc-shaped rack 505. The first gear 501 and the second gear 502 are meshed and connected. The first shaft 503 is connected with the first gear 501 by interference fit. The second shaft 504 is connected with the second gear 502 by interference fit. Both ends of the first shaft 503 and the second shaft 504 are rotatably connected to the hood 9 and the fixed plate 3 through bearings. Then, the arc-shaped rack 505 is fixed at the top outer edge of the rotating ring 10, the second gear 502 is meshed with the arc-shaped rack 505, the diameter ratio of the first gear 501 and the second gear 502 is one to two, the diameter ratio of the second gear 502 and the rotating ring 10 is one to five, the outer arc length of the arc-shaped rack 505 is one twelfth of the outer circumference of the rotating ring 10, and the rotation angle range of the arc-shaped rack 505 is -10°~10°.

[0033] For further information, see Figure 4The synchronization mechanism 6 includes a third rotating shaft 601 fixedly connected to the top of the first rotating shaft 503, and the array of the third rotating shaft 601 is provided with a plurality of them, wherein the top of one of the third rotating shafts 601 is fixedly connected to a stepper motor 602 via a coupling, a positioning plate 603 is fixedly fixed to one end of the stepper motor 602, and the positioning plate 603 is fixedly connected to the top of the hood 9, a third gear 604 is fixedly sleeved on the outer side of the third rotating shaft 601, and an internal toothed belt 605 is meshed and connected between the plurality of the third gears 604, and a speed increasing transmission member 606 is provided between the third rotating shaft 601 and the maintenance mechanism 7.

[0034] Principle of angle adjustment: when in use, by starting the stepper motor 602 to rotate, the stepper motor 602 drives one of the third rotating shafts 601 to rotate, thereby driving the third gear 604 and the first rotating shaft 503 to rotate, the first rotating shaft 503 drives the first gear 501 to rotate, the first gear 501 drives the second gear 502 to rotate, the second gear 502 drives the arc rack 505 to rotate, the arc rack 505 drives the rotating ring 10 to rotate, and the rotating ring 10 drives the line array camera 4 connected thereto to rotate, thereby realizing self-adjustment of the angle of the line array camera 4. At the same time, since the multiple third gears 604 are meshed and transmitted with an internal toothed belt 605, all the third gears 604 are driven to rotate synchronously under the drive of the internal toothed belt 605, so that the arc racks 505 at various positions rotate synchronously at the same angle, realizing synchronous adjustment of the angle of the line array camera 4, and being able to perform small angle rotation adjustment on the line array cameras 4 at multiple positions at one time. Compared with the existing method of manually rotating the rotating shaft, the number of line array cameras 4 adjusted each time is increased;

[0035] In addition, since the stepper motor 602 has the advantages of high precision, easy control, no cumulative error, high reliability, and fast response speed, when a specified angle needs to be adjusted, it is only necessary to program the stepper motor 602 to rotate a specified number of circles, and then transmit the angle output by the stepper motor 602 through the transmission action of the first gear 501, the second gear 502, and the third gear 604. For example, when the angle to be adjusted is 10°, at this time, because the diameter ratio of the first gear 501 and the second gear 502 is 1:2, and the diameter ratio of the second gear 502 and the rotating ring 10 is 1:5, the angles of the first gear 501, the second gear 502, and the rotating ring 10 are rotated to 100°, 50°, and 10°, respectively, and the angle at the output end of the stepper motor 602 is also 100°. Since the gears and the rotating ring 10 are in a state of precise meshing, each output of the stepper motor 602 can drive the rotating ring 10 to output a specified size, thereby achieving precise adjustment of the angle.

[0036] Example 2: Please refer to Figure 5 and Figure 6, this embodiment further explains the first embodiment, the maintenance mechanism 7 shown in the figure includes a No. 1 sealing cylinder 701 fixed to the outside of the oil box 11, the interior of the No. 1 sealing cylinder 701 is slidably connected to a No. 1 piston 702, one end of the No. 1 piston 702 is fixed to a No. 1 telescopic column 703, the No. 1 telescopic column 703 is slidably connected to the No. 1 sealing cylinder 701 through a sealing sleeve, a No. 1 spring 704 is fixed between the No. 1 piston 702 and the No. 1 sealing cylinder 701, the No. 1 spring 704 is arranged around the outside of the No. 1 telescopic column 703, the end of the No. 1 telescopic column 703 away from the No. 1 piston 702 is fixed to a No. 1 roller 705, the outer side of the No. 1 roller 705 is movably connected to a No. 1 cam 706, a linkage shaft 707 is interference-connected in the shaft hole of the No. 1 cam 706, the output end of the speed increasing transmission member 606 is transmission-connected with the linkage shaft 707, the linkage shaft 707 is installed on the outer wall of the hood 9 through a bearing seat, the end of the No. 1 sealing cylinder 701 away from the No. 1 roller 705 is connected to a liquid inlet pipe 708 through a one-way valve, the distal end of the liquid inlet pipe 708 is inserted into the interior of the oil box 11, the bottom of the No. 1 sealing cylinder 701 is connected to a liquid outlet pipe 709 through a one-way valve, the distal end of the liquid outlet pipe 709 is inserted into the interior of the hood 9 and is obliquely opposite to the No. 1 gear 501 and the No. 2 gear 502, and the bottom end of the linkage shaft 707 is transmission-connected with the input end of the dust removal mechanism 8;

[0037] At the same time, the speed increasing transmission member 606 includes a fourth gear 6061 fixedly sleeved with the third rotating shaft 601, a fifth gear 6062 is meshed on one side of the fourth gear 6061, a sixth gear 6063 is meshed on one side of the fifth gear 6062, one end of the center axis of the fifth gear 6062 is rotatably connected to the top of the hood 9 through a bearing, the sixth gear 6063 is fixedly sleeved with the linkage shaft 707, and the diameters of the fourth gear 6061, the fifth gear 6062 and the sixth gear 6063 are distributed in a decreasing manner.

[0038] When adjusting the angle, the third rotating shaft 601 will drive the fourth gear 6061 to rotate, the fourth gear 6061 will drive the fifth gear 6062 to rotate, the fifth gear 6062 will drive the sixth gear 6063 to rotate, and the sixth gear 6063 will drive the linkage shaft 707 to rotate. Since the diameters of the fourth gear 6061, the fifth gear 6062 and the sixth gear 6063 are distributed in decreasing order, the number of rotations of the sixth gear 6063 is greater than one circle, thereby causing the first cam 706 to rotate multiple circles, driving the first piston 702 to reciprocate multiple times in the first sealing cylinder 701. When the first piston 702 reciprocates, it will pass through the liquid inlet pipe 707. 8 The lubricating oil in the oil box 11 is sucked into the No. 1 sealing cylinder 701, and then discharged through the liquid outlet pipe 709. Since the distal end of the liquid outlet pipe 709 is inserted into the interior of the machine cover 9 and obliquely faces the No. 1 gear 501 and the No. 2 gear 502, the discharged lubricating oil will be directly sprinkled on the No. 1 gear 501 and the No. 2 gear 502, and the lubricating oil will be brought to the arc-shaped rack 505 through the meshing effect, so that the gears are automatically oiled and maintained, so that when adjusting the angle of the linear array camera 4, the angle adjustment mechanism 5 can be oiled and lubricated at the same time, which makes it more flexible and convenient to use the angle adjustment mechanism 5, and can increase the service life of the angle adjustment mechanism 5.

[0039] It should be noted that an infusion branch tube 7010 is fixedly connected to the liquid outlet tube 709, and the distal end of the infusion branch tube 7010 is opposite to the fourth gear 6061. The fourth gear 6061 is evenly provided with a plurality of through holes. The lubricating oil flowing out of the liquid outlet tube 709 will partially flow out from the infusion branch tube 7010, and the lubricating oil just discharged will be directly sprinkled on the third gear 604 and the fourth gear 6061, thereby facilitating the synchronous lubrication of the speed increasing transmission member 606 and the gears of the synchronization mechanism 6.

[0040] Example 3: Please refer to Figure 7This embodiment further illustrates other embodiments. The dust removal mechanism 8 shown in the figure includes a No. 2 sealing cylinder 801 fixed to the bottom of the fixed plate 3. A No. 2 piston 802 is slidably connected inside the No. 2 sealing cylinder 801. A No. 2 telescopic column 803 is fixed to one end of the No. 2 piston 802. The No. 2 telescopic column 803 is slidably connected to the No. 2 sealing cylinder 801 through a sealing sleeve. A No. 2 spring 804 is fixed between the No. 2 piston 802 and the No. 2 sealing cylinder 801. The No. 2 spring 804 is arranged around the outside of the No. 2 telescopic column 803, and the No. 2 telescopic column 803 is away from the No. 2 piston. A No. 2 roller 805 is fixed to one end of 802, and a No. 2 cam 806 is movably connected to the outer side of the No. 2 roller 805, and the bottom end of the linkage shaft 707 is interference connected with the axial hole of the No. 2 cam 806, and the end of the No. 2 sealing cylinder 801 away from the No. 2 roller 805 is connected to an air inlet pipe 807 through a one-way valve, and the bottom of the No. 2 sealing cylinder 801 is connected to an air outlet pipe 808 through a one-way valve, and the far end of the air outlet pipe 808 is fixedly connected to an air supply pipe 809, and a plurality of air nozzles 8010 are distributed in an array on one side of the air supply pipe 809, and the air nozzles 8010 are tilted upward and facing the lens of the linear array camera 4.

[0041] When adjusting the angle, the linkage shaft 707 drives the second cam 806 to rotate for multiple circles, and the second cam 806 drives the second piston 802 to reciprocate for multiple times in the second sealing tube 801. When the second piston 802 reciprocates, it will suck the external air into the second sealing tube 801 through the air inlet pipe 807, and then discharge it through the air outlet pipe 808. Since the far end of the air outlet pipe 808 is fixedly connected with the air supply pipe 809, and a plurality of air nozzles 8010 are arranged in an array on one side of the air supply pipe 809, the pressurized air forms a high-pressure airflow through the plurality of air nozzles 8010 and blows the lens surface of the linear array camera 4 to blow away the dust and impurities attached to the lens surface of the linear array camera 4. Therefore, the lens of the linear array camera 4 can be cleaned while the angle is adjusted, so as to ensure that the lens surface of the linear array camera 4 is clean and tidy, avoid impurities attached to the lens surface of the linear array camera 4 and affect the measurement result of the linear array camera 4, improve the measurement accuracy of the device, and no additional power structure is required.

[0042] It should be noted that an air intake hood 8011 is fixed to one end of the air intake pipe 807 away from the No. 2 sealing cylinder 801, and a filter net 8012 is provided on the inner side of the air intake hood 8011. The inhaled air is filtered through the filter net 8012, which can further reduce the dust in the external air from entering the No. 2 sealing cylinder 801 again.
