Description

Technical Field

[0001] The utility model relates to the field of laser measurement, in particular to a protective device for a standard sheet of a laser thickness gauge. Background Art

[0002] Laser measurement is a non-contact measurement that does not affect the movement of the object being measured. It has high accuracy, large measurement range, short detection time, and high spatial resolution. Among them, the laser thickness gauge is generally composed of two upper and lower laser displacement sensors that shoot at each other. The upper and lower laser displacement sensors are verified and calibrated by measuring standard sheets. It can be said that the slight changes in the shape and size of the standard sheet may directly affect the accuracy of the laser thickness gauge. During the production process of lithium battery pole pieces, some dust may adhere to the surface of the standard sheet, which may cause deviations in the verification or calibration results of the laser measuring instrument, thereby reducing the measurement accuracy.

[0028] Figure 1The protective device for the standard sheet of the laser thickness gauge in some embodiments of the utility model is shown. The laser thickness gauge includes a walking assembly 100 and a fixing assembly for carrying the standard sheet 110. The protective device can be used to protect the standard sheet 110 of the laser thickness gauge from dust and dirt sticking to the standard sheet 110. The protective device can include a supporting assembly 200 and a dust cover assembly 300, etc.

[0029] The support assembly 200 is installed at the front end of the walking assembly 100; the dust cover assembly 300 is installed on the fixed assembly and can be opened and closed above the standard sheet 110. The dust cover assembly 300 has an open state for exposing the standard sheet 110 and a closed state for covering the standard sheet 110. In a natural state, the dust cover assembly 300 is always in a closed state. When the walking assembly 100 moves forward to the first position, the support assembly 200 pushes the dust cover assembly 300 to switch the dust cover assembly 300 to an open state. When the dust cover assembly 300 is in a closed state, the dust cover assembly 300 can prevent dust and dirt from sticking to the standard sheet 110. When the walking assembly 100 moves to the first position, the dust cover assembly 300 moves to one side as the walking assembly 100 pushes it and becomes an open state. At this time, the standard sheet 110 is exposed outside the dust cover assembly 300, and the laser thickness gauge is calibrated by the standard sheet 110.

[0030] It can be understood that in some embodiments, the fixing component is disposed on the laser thickness gauge, and the fixing component carries both the standard sheet 110 and the dust cover component 300 .

[0031] It can be understood that in some embodiments, the dust cover assembly 300 can be opened to expose only a portion of the standard sheet 110 , and the laser thickness gauge can be calibrated using this portion of the standard sheet 110 .

[0032] It can be understood that in some embodiments, the traveling component can be fixed on the laser thickness gauge, and the fixed component can be moved relative to the traveling component, and the standard sheet moves into the laser thickness gauge for calibration along with the fixed component.

[0033] like Figures 2 to 4As shown, in some embodiments, the support assembly 200 may include a left support frame 210, a right support frame 220 and a support shaft 230. The left support frame 210 and the right support frame 220 are respectively fixed on both sides of the laser thickness gauge and face the standard sheet 110. The support shaft 230 is arranged at one end of the left support frame 210 and the right support frame 220 away from the laser thickness gauge, and is connected between the left support frame 210 and the right support frame 220. Since the dust cover assembly 300 is connected below the left support frame 210 and the right support frame 220, when the walking assembly 100 moves, it will cause a great impact on the support frame, which is easy to deform the support frame. The support frames arranged on both sides and the support shaft 230 in the middle will improve the overall rigidity of the support frame and improve the service life of the support assembly 200.

[0034] It can be understood that in some embodiments, the shape of the support shaft 230 can be other shapes, such as square, rectangular, etc.

[0035] In some embodiments, the left support frame 210 and the right support frame 220 are plate-shaped members with high longitudinal strength and easy processing.

[0036] In some embodiments, the protective device may include a follower 500 fixed on the dust cover assembly 300, and a push plate 510 fixed on the support assembly 200; the push plate 510 is provided with a push inclined surface which forms a set angle with the movement direction of the walking assembly 100, and the follower 500 cooperates with the push inclined surface to drive the dust cover assembly 300 to move to an open state. It can be understood that when the push plate 510 moves forward following the walking assembly 100, the push inclined surface will form a thrust on the follower 500, and because the follower 500 is fixed on the dust cover assembly 300, the thrust acts on the dust cover assembly 300 through the follower 500, so that the dust cover group 300 is pushed open, exposing the standard sheet 110.

[0037] In some embodiments, the protective device may include a follower assembly including a push plate 510 fixed on the dust cover assembly 300, and a follower 500 fixed on the support assembly 200; the push plate 510 is provided with a push inclined plane which forms a set angle with the movement direction of the walking assembly 100, and the push inclined plane cooperates with the follower 500 to drive the dust cover assembly 300 to move to an open state. It can be understood that when the follower 500 follows the walking assembly 100 to move forward, the follower 500 will form a thrust on the push inclined plane, and because the push plate 510 is fixed on the dust cover assembly 300, the thrust acts on the dust cover assembly 300 through the push plate 510, so that the dust cover group 300 is pushed open, exposing the standard sheet 110.

[0038] It can be understood that in some embodiments, the follower 500 can also be a cam follower 500 , and the roller of the cam follower 500 abuts against the push slope of the push plate 510 , which can greatly reduce the friction and increase the life of the follower 500 .

[0039] In some embodiments, the dust cover assembly 300 includes two dust cover assemblies 300 mirror-imaged on both sides of the standard sheet 110, two support assemblies 200 corresponding to the two dust cover assemblies 300, and two follower assemblies corresponding to the two dust cover assemblies 300 and the support assemblies 200. When the symmetrically designed dust cover assembly 300 moves to both sides, because the two dust cover assemblies 300 move in opposite directions, the momentum in opposite directions will offset each other, which is beneficial for the device to maintain momentum balance, reduce the vibration of the device itself, and prevent dust on the dust cover assembly 300 from falling onto the standard sheet 110.

[0040] In some embodiments, the protective device may include a support component 200 with a blowing component 400 at one end away from the walking component 100, the blowing component 400 includes a universal base 420 installed on the support component 200, and an air outlet 410 connected to the side of the universal base 420 close to the standard piece 110, and an air pipe adapter 430 connected to the side of the universal base 420 away from the standard piece 110. The blowing component 400 can blow air to clean the standard piece 110 when the dust cover assembly 300 is open.

[0041] It is understandable that the blowing component 400 can also be used for dust collection. It only needs to connect a negative pressure air source at the air pipe adapter 430 to clean the standard sheet by vacuuming it, so as to prevent dust from filling the entire space after the cleaning. It is understandable that the blowing component 400 can be connected to an air source that can freely switch between high-pressure air outlet and negative pressure air intake, so as to freely switch between blowing and dust collection.

[0042] like Figures 5 to 8 As shown, the support assembly 200 may include a reset assembly disposed between the dust cover assembly 300 and the fixed assembly in some embodiments, driving the dust cover assembly 300 to reset to a closed state. The reset assembly includes a spring support 341 fixed to the dust cover assembly 300, and a reset spring 340 having one end fixed to the spring support 341 and the other end fixed to the fixed assembly or another dust cover assembly 300. The reset spring 340 is respectively connected to two dust plate 310 assemblies. After the reset spring 340 is connected, it is in a stretched state. The two dust plate 310 assemblies are tightened and closed by the reset spring 340, thereby reducing the investment in other power components and reducing the manufacturing cost. It can be understood that the reset spring can also be other elastic parts, such as highly elastic telescopic parts.

[0043] In some embodiments, the dust cover assembly 300 may include a dust plate 310 covering the standard sheet 110 , and a slide rail 330 assembly disposed between the dust plate 310 and a fixing assembly.

[0044] It can be understood that in some embodiments, the dustproof plate 310 can also be a hollow tube inside, and the standard sheet 110 is movably arranged inside it. When in the shielding state, the standard sheet 110 is inside the dustproof plate 310, and the standard sheet 110 is completely enclosed and protected.

[0045] In some embodiments, the dustproof plate 310 may include an inner baffle plate 360 ​​disposed at the closed position of the two dustproof plates 310 , wherein the outer wall of the inner baffle plate 360 ​​is connected to the inner wall of the dustproof plate 310 , and the inner baffle plate 360 ​​may prevent dust from falling from the gap at the contact position of the two dustproof plates 310 .

[0046] In some embodiments, the slide rail 330 assembly may include a slide rail 330 fixed on a fixed assembly, and a slider 320 fixed under the dustproof plate 310; or the slide rail 330 assembly includes a slide rail 330 fixed under the dustproof plate 310, and a slider 320 fixed on a fixed group, the slide rail 330 is set perpendicular to the movement direction of the walking assembly 100, and the slider 320 performs a linear motion on the slide rail 330; the cooperation between the slide rail 330 and the slider 320 limits the freedom of the dustproof plate 310 assembly, and it can only move in one direction.

[0047] In some embodiments, the dust cover assembly 300 may include an anti-collision assembly, which includes an anti-collision plate 351 fixed below the dust plate 310, a soft anti-collision plug 350 fixed on the anti-collision plate 351, and an anti-collision screw 600 fixed on the fixed assembly corresponding to the soft anti-collision plug 350. When the dust plate 310 is pushed away, it may fly off the guide rail, and the anti-collision screw 600 will abut against the dust plate 310 to avoid direct collision between the anti-collision screw 600 and the movable baffle, and the soft anti-collision plug 350 is arranged at the movable baffle to reduce the impact. It can be understood that the soft anti-collision plug 350 can be other buffer components.

[0048] It can be understood that the above embodiments only express the preferred implementation methods of the present application, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application; it should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the present application; therefore, all equivalent changes and modifications made to the scope of the claims of the present application should fall within the scope of the claims of the present application.
