Description

Technical Field

[0001] This invention relates to the field of battery slurry testing technology, specifically to a device for testing the fineness of new material battery slurry. Background Technology

[0002] The electrochemical performance, cycle life, and safety stability of new energy batteries are closely related to the quality of battery slurry preparation. Slurry fineness is a core key indicator for measuring the quality of battery slurry preparation. Uniform and qualified slurry can ensure uniform electrode coating and sufficient electrochemical reaction. Conversely, excessively coarse slurry particles and uneven fineness will directly lead to problems such as electrode coating defects, increased battery internal resistance, and accelerated capacity decay, seriously affecting the production quality and performance of new energy batteries. Therefore, accurate detection of slurry fineness is an indispensable key process in battery production.

[0003] Currently, traditional battery slurry fineness testing mostly relies on manual inspection combined with a scraper fineness gauge. A few semi-automatic testing devices have relatively simple structural designs, resulting in numerous shortcomings in practical applications. 1. Traditional testing equipment has difficulty in achieving precise vertical alignment of the scraper and the scraper plate, and relies heavily on manual assembly and calibration, which is prone to assembly deviation. The inclined contact between the scraper and the scraper plate will lead to uneven scraping force and deviation of the scraping trajectory, resulting in non-standard slurry spreading effect, which directly causes large errors in fineness test data and low test accuracy. 2. The existing equipment lacks an adaptive leveling and positioning structure. During the testing process, the scraper and scraper blade are prone to horizontal deviation, which cannot guarantee the stability of the scraping operation. Furthermore, the slurry is prone to uneven thickness and irregular spreading during scraping, which further reduces the accuracy of the test. 3. Traditional equipment has poor scraper positioning and fixation. During the scraping process, the scraper is easily subject to external forces, resulting in slight displacement and shaking. Its stability is insufficient and it is very easy to disrupt the standardized scraping and detection conditions. 4. Manual calibration, alignment, and positioning are cumbersome procedures that rely on operator experience, resulting in poor consistency and low efficiency. This makes it impossible to meet the needs of large-scale, standardized batch testing of battery slurry and to adapt to the high-precision, high-stability slurry testing standards for new material batteries. This restricts the improvement of quality and efficiency of new energy battery slurry production quality inspection. Summary of the Invention

[0004] The purpose of this invention is to provide an apparatus for detecting the fineness of new material battery slurry, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for detecting the fineness of a new material battery slurry, comprising a base plate, a motor fixed to the side of the base plate, a lead screw fixed to the output end of the motor, a bearing connected to the base plate, the lead screw being connected to a movable stage to drive the movable stage to move left and right, a positioning mechanism on the movable stage to lock a scraper, the scraper being provided with scale lines, a back plate fixed to the base plate, a second support plate fixed to the back plate, a cylinder fixed to the second support plate, and a detection mechanism that can automatically align perpendicularly with the scraper being installed at the output end of the cylinder.

[0006] Preferably, the movable platform and the crossbar are slidably connected, and the crossbar is symmetrically distributed about the center line of the movable platform. The crossbar is fixed in the base plate. When the movable platform moves, the sliding guidance between the movable platform and the crossbar can ensure the stability of the movable platform's movement.

[0007] Preferably, the positioning mechanism includes a positioning plate and a side plate fixed on the movable platform. The side plates are symmetrically distributed about the center of the movable platform, and the upper surface of the positioning plate and the side plates is a beveled structure. The positioning plate and the side plates contact the scraper to achieve the positioning function. Through the function of the positioning plate and the side plates, the left side and front and rear positions of the scraper can be defined. Furthermore, the beveled structure of the upper surface of the positioning plate and the side plates can provide auxiliary guidance during scraper installation.

[0008] Preferably, a fixing frame is fixed to the side plate, and the side plate, fixing frame, and round rod are slidably connected. A first spring is fixed between the round rod and the fixing frame. At the same time, a locking block is fixed to one end of the round rod and is slidably connected to the side plate. The left and right sides of the locking block are inclined structures, and the other end of the round rod is slidably connected to an inclined panel. The inclined panels are symmetrically fixed to the base plate. Through the sliding action between the round rod and the inclined panel, a basic force can be provided for the movement of the locking block, thereby providing a basic guarantee for locking the scraper. In addition, with the elastic action of the first spring, a basic force can be provided for the automatic reset of the locking block, thereby providing a basic guarantee for unlocking the scraper.

[0009] Preferably, the scraper is provided with a material trough, and the scraper is also provided with positioning grooves symmetrically on the front and back. The positioning grooves and the locking blocks are engaged. The material troughs can ensure the normal operation of the test, and the locking action between the positioning grooves and the locking blocks can achieve the locking effect between the scraper and the movable table.

[0010] Preferably, a first support plate is fixed on the back plate, and a camera is fixed on the lower end face of the first support plate. The camera can be used to take pictures and record, thereby ensuring the normal operation of the device.

[0011] Preferably, the detection mechanism includes a mounting plate rotatably connected to the output end of the cylinder, a torsion spring connecting the mounting plate and the cylinder, and a sliding connection between the mounting plate and the vertical rod. The vertical rod is fixed to a positioning sleeve, and a second spring is fixed between the positioning sleeve and the mounting plate. The rotation between the mounting plate and the cylinder provides a basic guarantee for vertical adjustment of the device, and the sliding action between the vertical rod and the mounting plate and the elastic action of the second spring provides buffer protection for the scraper, effectively extending the service life of the device.

[0012] Preferably, a scraper is nested on the positioning sleeve, and the scraper contacts the limiting plate to achieve positioning. The limiting plate is rotatably connected to the positioning sleeve, and a torsion spring connects the limiting plate and the positioning sleeve. Through the action of the limiting plate, a basic guarantee can be provided for limiting the position of the scraper.

[0013] Preferably, the mounting plate is symmetrically fixed with fixing blocks on the left and right, and the fixing blocks are provided with inclined grooves. The inclined grooves are slidably connected to the sliding rods. The sliding rods are fixed to the brackets. The brackets are fixed to the vertical plates. The vertical plates are fixed with guide rods. The upper guide rods are slidably connected to the positioning sleeves. The guide rods are also fixed with clamping plates. The clamping plates contact the scraper to achieve clamping and fixing. Through the sliding action between the inclined grooves and the sliding rods, a basic force can be provided for the movement of the vertical plates, guide rods and clamping plates. With the clamping plates clamping and positioning the scraper, it can be ensured that the scraper and the lower end face of the positioning sleeve are in a perpendicular state, thereby ensuring the perpendicular contact between the scraper and the scraper plate.

[0014] Preferably, a square rod is slidably connected to the positioning sleeve, and a counterweight is fixed to the lower end of the square rod. A rolling steel ball is installed on the lower end face of the counterweight, and the lower end face of the steel ball is lower than the lower end face of the scraper. The steel ball can roll in contact with the scraper. A baffle is provided above the square rod and is fixed to the positioning sleeve. The distance between the upper end face of the square rod and the baffle is equal to the distance between the lower end face of the steel ball and the lower end face of the scraper. Through the above structure, the vertical adjustment function of the device can be realized, ensuring the accuracy of the detection data.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This device for detecting the fineness of new material battery slurry features a detection mechanism. Driven by a cylinder, the entire detection mechanism moves downwards. Utilizing the cooperative structure of counterweights, steel balls, a square rod, and a baffle, and taking advantage of the steel balls' initial contact with the scraper, combined with the synchronous adaptive leveling of four sets of counterweights, the device automatically corrects the horizontal state of the positioning sleeve, ensuring that the lower end face of the positioning sleeve is completely parallel to the scraper. Simultaneously, through the sliding cooperation of the inclined groove of the fixed block and the sliding rod, and the guiding transmission of the guide rod, the clamping plate automatically clamps the positioning scraper, forcing the scraper to maintain an absolutely perpendicular state with the positioning sleeve and the scraper. This completely eliminates the traditional manual calibration and alignment method, effectively avoiding angular deviations caused by manual assembly and equipment assembly, and solving the problems of uneven scraping and distorted detection data due to scraper tilt, effectively ensuring the accuracy of slurry fineness detection. 2. This device for detecting the fineness of new material battery slurry uses a structure design that matches the distance between the square rod, counterweight, steel balls, and baffle to ensure synchronous linkage between leveling and scraper contact operations. During the detection and downward movement process, the self-adaptive floating characteristics of the counterweight can automatically adapt to the installation deviation of the scraper, completing multi-point synchronous leveling and positioning. This ensures that the scraper pressing depth, contact angle, and scraping posture are completely consistent in each detection operation, effectively solving the problems of large differences in single detection conditions and poor consistency of batch detection data in traditional equipment. It significantly improves the repeatability and reliability of multiple batches of slurry detection, and meets the standardized batch quality inspection requirements of new material battery slurry. 3. This device for detecting the fineness of new material battery slurry is equipped with a positioning mechanism. The positioning plate and side plate achieve initial positioning of the scraper in the left and front-back directions. Simultaneously, during the movement of the movable table, the round rod engages with the inclined surface of the inclined plate, driving the locking block to automatically engage and lock with the positioning groove of the scraper, achieving omnidirectional fixation of the scraper. During the process of the motor-driven movable table moving the scraper at a uniform speed to scrape the material, problems such as scraper wobbling, offset, and displacement are completely eliminated, ensuring a smooth and interference-free scraping process, maintaining standardized testing conditions, avoiding abnormal slurry spreading caused by scraper displacement, and ensuring the stability and standardization of the testing process. 4. This device for detecting the fineness of new material battery slurry achieves uniform scraper feeding through a motor-driven lead screw, automatic alignment, leveling, and clamping of the detection mechanism driven by a cylinder, and automatic scraper locking during the movement process. The entire process eliminates the need for tedious manual calibration and fixing. Only manual placement of the slurry and assembly of the scraper are required to automatically complete the entire scraping and imaging detection process, greatly simplifying the operation steps, reducing manual operation errors and labor costs, and effectively improving the overall efficiency of slurry fineness detection. It is suitable for the quality inspection needs of industrial mass production. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-7 This invention provides a technical solution: a device for detecting the fineness of a new material battery slurry, comprising a base plate 1, a motor 2 fixed to the side of the base plate 1, a lead screw 3 fixed to the output end of the motor 2, the lead screw 3 being bearing-connected to the base plate 1, the lead screw 3 being connected to a movable table 4 to drive the movable table 4 to move left and right, a positioning mechanism on the movable table 4 to lock a scraper 6, the scraper 6 being provided with scale lines, a back plate 7 fixed to the base plate 1, a second support plate 8 fixed to the back plate 7, a cylinder 9 fixed to the second support plate 8, and a detection mechanism 10 installed at the output end of the cylinder 9 that can automatically align vertically with the scraper 6.

[0020] The scraper 6 has a material trough 601 and symmetrically arranged positioning grooves 602. The positioning grooves 602 are engaged with the locking block 406. The detection mechanism 10 includes a mounting plate 1001 that is rotatably connected to the output end of the cylinder 9. A torsion spring is connected between the mounting plate 1001 and the cylinder 9. The mounting plate 1001 is slidably connected to the vertical rod 1002. The vertical rod 1002 is fixed on the positioning sleeve 1003. A second spring 1004 is fixed between the positioning sleeve 1003 and the mounting plate 1001. A scraper 1005 is nested on the positioning sleeve 1003. The scraper 1005 contacts the limiting plate 1006 to achieve positioning. The limiting plate 1006 is rotatably connected to the positioning sleeve 1003. A torsion spring is connected between the limiting plate 1006 and the positioning sleeve 1003. When using this device for detecting the fineness of new material battery slurry, such as Figures 1-7 As shown, first, the scraper 6 is placed on the movable table 4, and the scraper 6 contacts the positioning plate 401 and the side plate 402 to achieve left-side and front-back positioning. Then, the slurry to be tested is placed in a deeper position on the right side of the material tank 601. Then, by rotating the limiting plate 1006, the scraper 1005 and the positioning sleeve 1003 are nested and installed. After installation, by loosening the limiting plate 1006, the limiting plate 1006 can be reset to a horizontal state under the elastic action of the torsion spring. Through the action of the limiting plate 1006, the front-back positioning of the scraper 1005 can be achieved, thus completing the preparation work. Fixing blocks 1007 are symmetrically fixed on the mounting plate 1001, and the fixing blocks 1007 have inclined grooves 1008. The inclined grooves 1008 are slidably connected to the slide rods 1009. The slide rods 1009 are fixed to the bracket 1010. The bracket 1010 is fixed to the vertical plate 1011, and a guide rod 1012 is fixed on the vertical plate 1011. The upper guide rod 1012 is slidably connected to the positioning sleeve 1003. A clamping plate 1013 is also fixed on the guide rod 1012. The clamping plate 1013 contacts the scraper 1005 to achieve clamping and fixing. A square rod 1014 is slidably connected to the positioning sleeve 1003, and a counterweight 1015 is fixed at the lower end of the square rod 1014. A rolling steel ball 1016 is installed on the lower end face of the counterweight 1015. At the same time, the lower end face of the steel ball 1016 is lower than the lower end face of the scraper 1005. The steel ball 1016 can roll when it contacts the scraper 6. A baffle 1017 is provided above the square rod 1014 and is fixed on the positioning sleeve 1003. The distance between the upper end face of the square rod 1014 and the baffle 1017 is equal to the distance between the lower end face of the steel ball 1016 and the lower end face of the scraper 1005. During testing, such as Figures 1-7As shown, by controlling the extension of cylinder 9, the mounting plate 1001, positioning sleeve 1003, scraper 1005, counterweight 1015, and steel ball 1016 can be moved downwards. Since the lower end face of steel ball 1016 is lower than the lower end face of scraper 1005, steel ball 1016 can contact scraper 6 first. At this time, counterweight 1015 is subjected to force and moves relative to positioning sleeve 1003. With the sliding guide effect between square rod 1014 and positioning sleeve 1003, the stability of the movement of counterweight 1015 can be ensured. When the lower end face of positioning sleeve 1003 is parallel to scraper 6, the four counterweights 1015 move upwards synchronously, so that the four... The upper ends of the square rods 1014 simultaneously contact the baffle 1017 to achieve positioning. When the lower end face of the positioning sleeve 1003 is parallel to the scraper 6, the two square rods 1014 on one side will first contact the baffle 1017 at the corresponding position. Through the continued extension of the cylinder 9, the square rods 1014 on that side can exert a force on the baffle 1017, thereby causing the positioning sleeve 1003 to rotate relative to the output end of the cylinder 9 until the upper ends of all four square rods 1014 are in contact with the baffle 1017. At this time, the lower end face of the positioning sleeve 1003 can be kept parallel to the scraper 6, providing a basic guarantee for the vertical positioning of the scraper 1005 and the scraper 6 in the future. After the upper ends of the four square rods 1014 contact the baffle 1017, since the distance between the upper surface of the square rod 1014 and the baffle 1017 is equal to the distance between the lower surface of the steel ball 1016 and the lower surface of the scraper 1005, the scraper 1005 simultaneously contacts the upper surface of the scraper 6. Through the continued extension of the cylinder 9, the mounting plate 1001 can be moved relative to the positioning sleeve 1003 under force. With the sliding guide effect between the mounting plate 1001 and the vertical rod 1002, the stability of the movement of the mounting plate 1001 can be ensured, thereby driving the fixing block 1007 to move downward. With the sliding effect between the inclined groove 1008 and the sliding rod 1009, the bracket 1010 and the vertical plate 1011 can be forced towards the positioning sleeve 1003. The movement of the bracket 1010 and the vertical plate 1011 is ensured by the sliding guide action between the upper guide rod 1012 and the positioning sleeve 1003. The sliding of the guide rod 1012 can also drive the clamping plate 1013 to move simultaneously until the clamping plate 1013 contacts the scraper 1005 to achieve clamping and positioning. The clamping and positioning action of the clamping plate 1013 on the scraper 1005 can keep the scraper 1005 and the lower end face of the positioning sleeve 1003 perpendicular, thereby ensuring the perpendicularity between the scraper 1005 and the scraper 6. This avoids the scraper 1005 and the scraper 6 not being perpendicular due to the assembly error between the scraper 1005 and the positioning sleeve 1003, which would affect the accuracy of subsequent test data. The movable platform 4 and the crossbar 5 are slidably connected, and the crossbar 5 is symmetrically distributed about the center line of the movable platform 4, and the crossbar 5 is fixed inside the base plate 1; the positioning mechanism includes a positioning plate 401 and a side plate 402 fixed on the movable platform 4, and the side plate 402 is symmetrically distributed about the center of the movable platform 4, and the upper surface of the positioning plate 401 and the side plate 402 is a beveled structure. At the same time, the positioning plate 401 and the side plate 402 contact the scraper 6 to achieve the positioning function; a fixing bracket 403 is fixed on the side plate 402, and the side plate 402... The fixed frame 403 and the round rod 404 are slidably connected, and a first spring 405 is fixed between the round rod 404 and the fixed frame 403. At the same time, a locking block 406 is fixed to one end of the round rod 404 and is slidably connected to the side plate 402. The left and right sides of the locking block 406 are inclined structures. The other end of the round rod 404 is slidably connected to the inclined plate 407, and the inclined plate 407 is symmetrically fixed to the base plate 1. A first support plate 701 is fixed on the back plate 7, and a camera 702 is fixed to the lower end face of the first support plate 701. After the scraper 1005 makes perpendicular contact with the scraper 6, as Figures 1-7 As shown, by starting the motor 2 to drive the lead screw 3 to rotate, the movable table 4, positioning plate 401, fixed frame 403 and scraper 6 can be moved relative to the scraper 1005. With the sliding guide between the movable table 4 and the crossbar 5, the stability of the scraper 6 movement can be ensured. When the fixed frame 403 moves, it drives the round rod 404 to move synchronously. With the sliding action between the round rod 404 and the inclined plate 407, the round rod 404 can be moved relative to the fixed frame 403 under force, so that the locking block 406 moves and engages with the positioning groove 602, thereby realizing the locking effect between the scraper 6 and the movable table 4, ensuring the stability of the scraper 6. When the round rod 404 slides to the plane of the inclined plate 407, the scraper 1005 is in contact with the slurry on the scraper 6 to realize the scraping detection function, ensuring the normal progress of the detection. After the scraping is completed, the extension position of the slurry in the material tank 601 can be photographed by the camera 702. The fineness of the slurry can be determined by referring to the scale lines on the scraper 6.
