Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery diaphragms, and particularly relates to a lithium battery diaphragm detector. Background Art

[0002] The lithium battery diaphragm is an important component in a lithium ion battery, mainly used to separate the positive and negative electrodes of the battery to prevent direct contact between the electrodes, thereby avoiding short circuits and battery failures.

[0003] Chinese Patent with the publication number CN219512118U discloses a lithium battery diaphragm detector. The working principle of this device is that when in use, the hand wheel is rotated. The hand wheel drives the bidirectional lead screw to rotate. The bidirectional lead screw drives two sliders to move horizontally, approaching or moving away from each other, so as to realize the adjustment of the light intensity. The two sliders drive two rotating shafts to move. At this time, the positions of two lighting lamps can be adjusted. At the same time, when the gear moves, it will start to rotate because it meshes with the rack. The gear drives the wiring board to rotate. The wiring board drives the lamp shade and the lighting lamp to rotate, so as to adjust the irradiation angle of the light source, and the adjustment of the irradiation angle and the light intensity are carried out synchronously without manual adjustment again.

[0004] The deficiencies of the above prior art solutions are as follows: The common materials of lithium battery diaphragms include materials such as polyethylene, polypropylene, and polyimide. At the same time, some lithium battery diaphragms are usually coated with coatings, such as polymer coatings, nano coatings, and metal coatings, which makes the photosensitivity and reflectivity of the lithium battery diaphragms in the material state different. Different photosensitivity and reflectivity will affect the intensity and characteristics of the optical signals received by the detection equipment. Therefore, it is necessary to adjust the light intensity and irradiation angle accordingly according to the requirements. However, the light distance and the light irradiation angle of the above device have always been in a linkage state and cannot be adjusted separately. This may cause deviations in the optical system when the detection equipment detects lithium battery diaphragms of different types and different coatings, thereby affecting the accuracy of the detection results. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a lithium battery diaphragm detector to solve the technical problem that in the prior art, the light distance and the light irradiation angle have always been in a linkage state and cannot be adjusted separately, thus unable to meet the test requirements for lithium battery diaphragms of different types and different coatings.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0023] As Figures 1-4 shown, a lithium battery separator detector includes an installation plate track 1, a first lighting component, a second lighting component, a spacing adjustment component for autonomously adjusting the spacing between the lamp tubes 6, and an angle adjustment component for autonomously adjusting the irradiation angle of the lamp tubes 6. The first lighting component includes a condenser plate frame 5 provided on the installation plate track 1. The condenser plate frame 5 can achieve light focusing. The lamp tubes 6 are installed inside the condenser plate frame 5. The first lighting component has the same structure as the second lighting component, and the two are arranged in parallel inside the installation plate track 1. The spacing adjustment component and the angle adjustment component are both provided on the installation plate track 1 and are both matched with the first lighting component and the second lighting component. When it is necessary to switch the test of lithium battery separators with different materials or different coatings, the spacing between the two groups of lamp tubes 6 can be adjusted through the spacing adjustment component according to the detection standards of the material or coating, thereby adjusting the light intensity of the lamp tubes 6 irradiating in the middle of the installation plate track 1. The irradiation angle of the light of the lamp tubes 6 is adjusted through the angle adjustment component, so as to adjust the position of the light and shadow, so as to achieve the best lighting effect relative to the material or coating, make the characteristics of the lithium battery separator clearer, thereby improving the detection accuracy and reliability, and realizing the detection of the lithium battery separator.

[0024] In some specific implementation schemes, in order to realize the adjustment of the spacing, the spacing adjustment component includes a first guide box 2 fixedly connected to one side of the installation plate track 1, and a second guide box 7 fixedly connected to the other side of the installation plate track 1. Two groups of sliders 4 are slidably connected inside the first guide box 2 and the second guide box 7. Both ends of each condenser plate frame 5 are rotatably connected to the corresponding sliders 4. At this time, the two groups of condenser plate frames 5 are arranged parallel to each other. A threaded rod 3 is rotatably connected inside the first guide box 2. The thread directions on both sides of the threaded rod 3 are opposite. The threaded rod 3 is threadedly connected to the two groups of sliders 4 inside the first guide box 2. When it is necessary to adjust the spacing between the two groups of lamp tubes 6, the threaded rod 3 can be rotated. The threaded rod 3 drives the sliders 4 on both sides to approach or move away from each other. The sliders 4 drive the condenser plate frame 5 and the lamp tubes 6 to move synchronously, thereby realizing the adjustment of the spacing between the lamp tubes 6, and then adjusting the light intensity irradiating in the middle of the installation plate track 1.

[0025] In some specific embodiments, in order to adjust the irradiation angle of the lamp tube 6, the angle adjustment assembly includes a first driving wheel 8 and a second driving wheel 9. The first driving wheel 8 is rotatably connected to a set of sliders 4 inside the second guiding box 7, and the second driving wheel 9 is rotatably connected to another set of sliders 4 inside the second guiding box 7. The first driving wheel 8 and the second driving wheel 9 are respectively coaxially and fixedly connected to the corresponding condenser plate frames 5. A driving mechanism is arranged inside the second guiding box 7 and is matched with the first driving wheel 8 and the second driving wheel 9. The driving mechanism can drive the first driving wheel 8 and the second driving wheel 9 to rotate synchronously and towards each other; by means of the driving mechanism, the first driving wheel 8 and the second driving wheel 9 rotate synchronously and towards each other, so that the first driving wheel 8 and the second driving wheel 9 drive the condenser plate frames 5 connected thereto to rotate, thereby enabling the two groups of condenser plate frames 5 to rotate synchronously and towards each other, so as to facilitate the control of the irradiation angle.

[0026] In some specific embodiments, in order to realize the rotation of the first driving wheel 8 and the second driving wheel 9 towards each other, the driving mechanism includes a transmission plate 12 arranged inside the second guiding box 7. A driving wheel 10 is rotatably connected to the slider 4 provided with the second driving wheel 9. The driving wheel 10 is matched with the second driving wheel 9 and can drive the second driving wheel 9 to rotate. Both the first driving wheel 8 and the driving wheel 10 are matched with the transmission plate 12. The driving wheel 10 drives the first driving wheel 8 to rotate by driving the transmission plate 12 to move. A knob 15 is coaxially and fixedly connected to the driving wheel 10. A rotation range 17 is arranged on the slider 4 at one end of a group of condenser plate frames 5; when it is necessary to drive the first driving wheel 8 and the second driving wheel 9 to rotate towards each other, the knob 15 can be rotated. The knob 15 drives the driving wheel 10 to rotate, the driving wheel 10 drives the second driving wheel 9 to rotate, the second driving wheel 9 drives the corresponding condenser plate frame 5 to rotate, and at the same time the driving wheel 10 drives the transmission plate 12 to move, the transmission plate 12 drives the first driving wheel 8 to rotate, and the first driving wheel 8 drives the corresponding condenser plate frame 5 to rotate. The two groups of condenser plate frames 5 rotate simultaneously under the action of the driving wheel 10, and the rotation range 17 is referred to during the rotation process, so as to facilitate the precise adjustment of the irradiation angle.

[0027] In some specific embodiments, for the convenience of correcting the deflection angle of the condenser plate frame 5, a first alignment mark 18 is provided on each group of condenser plate frames 5, and a second alignment mark 20 is provided on the slider 4 at one end of the other group of condenser plate frames 5. A support plate 13 is arranged at the bottom of the transmission plate 12 in a matching manner. A spring 14 is fixedly connected to the bottom of the support plate 13, and the bottom of the spring 14 is fixedly connected to the inner wall of the second guide box 7. A fixing bolt 11 matching with the transmission plate 12 is threadedly connected to the second guide box 7; under normal circumstances, the two groups of condenser plate frames 5 should be symmetric with each other and rotate synchronously in a mirror image manner. When the offset angle of one group of condenser plate frames 5 cannot be mirror-image matched with the offset angle of the other group of condenser plate frames 5, the fixing bolt 11 can be rotated. The fixing bolt 11 drives the support plate 13 and the transmission plate 12 to squeeze the spring 14 and move downward, so that the transmission plate 12 is not in contact with the first driving wheel 8 and the driving wheel 10. At this time, referring to the first alignment mark 18 on each group of condenser plate frames 5, making it correspond to the second alignment mark 20 or the corresponding mark in the rotation range 17, the symmetric state of the two groups of condenser plate frames 5 is re-established. After the adjustment is completed, the fixing bolt 11 is rotated in the reverse direction, so that the support plate 13 and the transmission plate 12 are reset under the action of the spring 14, and the transmission plate 12 presses the first driving wheel 8 and the driving wheel 10 again to maintain their synchronous state, so as to maintain the corresponding state of the offset angles of the two groups of condenser plate frames 5.

[0028] In some specific embodiments, for the convenience of adjusting the distance between the lamp tubes 6, a distance comparison line 19 is provided on each group of condenser plate frames 5, and a transverse movement range 16 matching with the distance comparison line 19 is provided on the first guide box 2. When adjusting the lamp tubes 6, the position corresponding to the distance comparison line 19 on each group of condenser plate frames 5 and the transverse movement range 16 can be observed with reference to the transverse movement range 16, so as to accurately adjust the distance between the lamp tubes 6, and the light intensity is corresponding to the distance between the lamp tubes 6, so as to facilitate the accurate adjustment of the light intensity.

[0029] For the convenience of those skilled in the art to understand the embodiments of this solution, the working principle of the embodiments of this solution will be described below in combination with a specific application scenario:

[0030] When it is necessary to switch the test of lithium battery diaphragms with different materials or different coatings, the distance between the two groups of lamp tubes 6 can be adjusted through the distance adjustment component according to the detection standards of the material or coating, so as to adjust the light intensity irradiated by the lamp tubes 6 in the middle of the mounting plate track 1. When it is necessary to adjust the distance between the two groups of lamp tubes 6, the threaded rod 3 can be rotated. The threaded rod 3 drives the sliders 4 on both sides to approach or move away from each other. The sliders 4 drive the condenser plate frame 5 and the lamp tubes 6 to move synchronously, thus realizing the adjustment of the distance between the lamp tubes 6. When adjusting the lamp tubes 6, the position corresponding to the distance ratio line 19 on each condenser plate frame 5 and the transverse movement range 16 can be observed with reference to the transverse movement range 16, so as to realize the precise adjustment of the distance between the lamp tubes 6, and the light intensity is corresponded to the distance between the lamp tubes 6, thus facilitating the precise adjustment of the light intensity;

[0031] When it is necessary to drive the two groups of condenser plate frames 5 to rotate towards each other, the knob 15 can be rotated. The knob 15 drives the driving wheel 10 to rotate. The driving wheel 10 drives the second driving wheel 9 to rotate. The second driving wheel 9 drives the corresponding condenser plate frame 5 to rotate. At the same time, the driving wheel 10 drives the transmission plate 12 to move. The transmission plate 12 drives the first driving wheel 8 to rotate. The first driving wheel 8 drives the corresponding condenser plate frame 5 to rotate, so that the two groups of condenser plate frames 5 rotate simultaneously under the action of the driving wheel 10. During the rotation process, the rotation range 17 is referred to, so as to facilitate the precise adjustment of the irradiation angle, so as to achieve the best light effect relative to the material or coating, make the characteristics of the lithium battery diaphragm clearer, thus improving the detection accuracy and reliability, and realizing the detection of the lithium battery diaphragm;

[0032] Normally, the two groups of condenser plate frames 5 should be symmetrical with each other and rotate synchronously in a mirror image when rotating. When the offset angle of one group of condenser plate frames 5 cannot be mirror-imaged with the offset angle of the other group of condenser plate frames 5, the fixing bolt 11 can be rotated. The fixing bolt 11 drives the support plate 13 and the transmission plate 12 to squeeze the spring 14 and move downward, so that the transmission plate 12 is not in contact with the first driving wheel 8 and the driving wheel 10. At this time, with reference to the first comparison marking line 18 on each condenser plate frame 5, it is made to correspond to the second comparison marking line 20 or the corresponding marking line in the rotation range 17, and the symmetrical state of the two groups of condenser plate frames 5 is re-established. After the adjustment is completed, the fixing bolt 11 is rotated in the reverse direction, so that the support plate 13 and the transmission plate 12 are reset under the action of the spring 14, and the transmission plate 12 presses the first driving wheel 8 and the driving wheel 10 again to maintain their synchronous state, so as to maintain the corresponding state of the offset angles of the two groups of condenser plate frames 5.

[0033] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
