[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0055] See also Figure 1-9 The present invention discloses a metal plate surface scraping device, comprising:

[0056] A frame 1, the frame 1 is used to place the metal plate 01, and the frame 1 is provided with supporting parts 2 for carrying the tabs of the metal plate 01 in parallel. The metal plates 01 are arranged in equal intervals in the frame 1;

[0057] The movable parts 3 are two groups, and the two groups of movable parts 3 are movably arranged in the supporting part 2;

[0058] The cleaning part 4 is arranged between the two groups of the moving parts 3. The moving parts 3 are used to drive the cleaning part 4 to move along the arrangement direction of the metal plates 01 and clean and scrape the surface of the metal plates 01;

[0059] Specifically, the cleaning part 4 includes a cleaning scraper 41, which is provided with a hollow groove 411 for the metal plate 01 to pass through, and the cleaning scraper 41 is also provided with scraper brackets 42 distributed on both sides of the hollow groove 411. The two groups of scraper brackets 42 are provided with inclined scrapers 43 that contact the metal plate 01. Figure 1 As shown, the two groups of inclined scrapers 43 are arranged obliquely downward to scrape off the protrusions on the surface of the metal plate 01 when the cleaning scraper 41 moves from top to bottom;

[0060] The scraper bracket 42 is provided with a one-way locking piece corresponding to the inclined scraper 43. The one-way locking piece is used to adjust the two groups of inclined scrapers 43 to adapt to the thickness of the metal plate 01 when the metal plate 01 enters between the two inclined scrapers 43, and lock the two groups of inclined scrapers 43 when the metal plate 01 leaves between the two inclined scrapers 43, so that the inclined scrapers 43 can scrape off the protrusions on the surface of the metal plate 01.

[0061] It should be further explained that the moving part 3 includes a translation mechanism and a lifting mechanism;

[0062] The translation mechanism is used to drive the cleaning part 4 to move along the arrangement direction of the metal plates 01;

[0063] The lifting mechanism is used to drive the cleaning part 4 to move along the height direction of the metal plate 01.

[0064] In a preferred embodiment, two groups of scraper brackets 42 are slidably arranged on the cleaning scraper platform 41, and a vibration groove is provided on the cleaning scraper platform 41 for the horizontal movement of the scraper bracket 42. The scraper bracket 42 is provided with a limit block located above the vibration groove, wherein the limit block is used to support the scraper bracket 42 to be able to move horizontally along the vibration groove;

[0065] A vibration bracket 44 is connected between the two groups of scraper brackets 42, and abutment protrusions are provided on both sides of the vibration bracket 44;

[0066] The two sets of lifting mechanisms are provided with vibration racks 34 corresponding to the abutment protrusions on both sides of the vibration bracket 44;

[0067] The two groups of vibration racks 34 are provided with staggered vibration protrusions on opposite sides, so as to drive the inclined scraper 43 to vibrate horizontally for scraping during the cleaning and scraping process of the cleaning part 4 through the cooperation between the vibration protrusion and the resistance protrusion.

[0068] In the above structure, when the cleaning part 4 is running, the cleaning scraper 41 is lifted by the lifting mechanism, and the inclined scraper 43 arranged inside it is in contact with both sides of the metal plate 01 under the action of the one-way locking member, and then in the process of descending driven by the lifting mechanism, the inclined scraper 43 is used to scrape off the protrusions protruding from the surface of the metal plate 01. During this process, due to the setting of the vibration bracket 44, the interference protrusions at both ends of the vibration bracket 44 engage with the vibration racks 34 staggered on both sides thereof, which will produce a translational action, aiming to change the cutting path during the downward movement cutting process, so that the inclined scraper 43 changes from vertical cutting to oblique cutting. Compared with vertical cutting, during oblique cutting, the cutting force is dispersed, the tool wear is more evenly, the local overload of the tool is reduced, and the service life of the tool is extended. In addition, the oblique cutting can more smoothly remove surface protrusions, reduce surface burrs and knife marks, improve the surface finish of the processed plate, and improve product quality.

[0069] In another preferred embodiment, the two sets of lifting mechanisms are further provided with a third driving unit for driving the vibration rack 34 to move up and down;

[0070] The third driving unit is used to drive the two groups of the vibrating racks 34 to move up and down, so as to drive the vibrating bracket 44 to produce translational vibration through the staggered vibrating protrusions arranged thereon, so as to perform a horizontal cutting action when the inclined scraper 43 contacts the protrusions on the surface of the metal plate, and as the cleaning scraper table 41 continues to descend, the purpose of cutting and scraping away the stubborn protrusions is achieved.

[0071] It is easy to imagine that the translation mechanism includes a first screw rod 31 and a first driving unit 32 driving the first screw rod 31 to rotate;

[0072] The first screw rod 31 is arranged on both sides of the metal plate 01 along the arrangement direction of the metal plate 01;

[0073] The first screw rod 31 is rotatably disposed in the support portion 2 .

[0074] Furthermore, the lifting mechanism includes a lifting seat rotatably connected to the first screw rod 31;

[0075] The lifting seat is provided with a second driving unit 33 and a second screw rod 331 provided at the output end thereof, and the lifting seat is also provided with a guide rail 332;

[0076] The two ends of the cleaning scraper 41 are provided with connection holes 412 adapted to the second screw rod 331 and the guide rail 332;

[0077] The lifting mechanism is used to drive the cleaning scraper 41 to move along the height direction of the metal plate 01 through the engagement of the second screw rod 331 with the connecting hole 412.

[0078] It should be added that the first drive unit 32 and the second drive unit 33 are both servo motors. The above-mentioned translation mechanism and lifting mechanism are conventional technical means that are easily thought of by technical personnel in this field. Their purpose is to drive the cleaning part 4 to move along the X and Z axes, so they are not described in detail in this application.

[0079] In a preferred embodiment, in order to prevent the metal plate 01 from shaking during the cutting process, the support portion 2 is provided with a locking portion adapted to the tab of the metal plate 01;

[0080] The locking portion includes two sets of hinged seats 21, and the two sets of hinged seats 21 are oppositely provided with L-shaped hinged rods 22;

[0081] The top end of the L-shaped hinged rod 22 is rotatably provided with a lock plate 23 for contacting the metal plate 01;

[0082] The bottom end of the L-shaped hinge rod 22 is provided with a bearing plate 24 that contacts the metal plate 01 .

[0083] When each metal plate 01 is placed in the locking part corresponding to the support part 2, the supporting plate 24 contacts the pole ear of the metal plate 01. At the same time, through its own weight, it can press down the L-shaped hinged rod 22 to rotate, so that the rotating locking plate 23 is relatively in contact with the two sides of the pole ear, thereby realizing self-locking of the metal plate 01, so as to ensure the stability of the metal plate 01 when the inclined scraper 43 vibrates to scrape the protrusions on the surface of the metal plate 01, and avoid its shaking affecting the scraping efficiency and product quality.

[0084] It should be further explained that the one-way locking member includes a connecting ring provided at the top end of the scraper bracket 42;

[0085] The inclined scraper 43 is provided with a connecting shaft 431 adapted to the connecting ring, and the connecting shaft 431 is provided with a one-way locking tooth;

[0086] A non-return lock buckle 421 is provided in the connecting ring and contacts the one-way latch teeth;

[0087] The non-return lock 421 is used to allow the inclined scraper 43 to rotate in one direction.

[0088] Furthermore, a reset torsion spring is provided in the connecting ring to drive the connecting shaft 431 to reset.

[0089] The connecting ring is further provided with a reset unit 422 for driving the non-return lock 421 to retract;

[0090] The reset unit 422 is used to drive the non-return lock 421 to retract to unlock the one-way tooth, and drive the inclined scraper 43 to rotate relatively through the reset torsion spring to adapt to the subsequent metal plate 01.

[0091] With the above-mentioned structural arrangement, since the two groups of inclined scrapers 43 are arranged to be inclined downward, during the lifting process of the inclined scrapers 43, the inclined scrapers 43 can adapt to metal plates 01 of different thicknesses and adhere to the surface of the metal plate 01 until they are lifted to the top of the metal plate 01. Then, the inclined scrapers 43 move downward and, due to being locked by the non-return lock 421, they can remove the protrusions on the surface of the metal plate in a fixed posture.

[0092] After the processing of the current metal plate 01 is completed, the non-return lock 421 can be retracted by the reset unit 422, and the reset torsion spring drives the inclined scraper 43 to rotate relatively, so as to be adapted to the subsequent metal plate 01.

[0093] Finally, it should be noted that Figure 9 As shown, a detection unit 45 is provided on the cleaning scraper 41, and the detection unit 45 is used to detect protrusions on the surface of the metal plate 01;

[0094] Specifically, since the position of each metal plate 01 is fixed, the user can control the position of the cleaning scraper 41 through the servo motor so that the detection end of the detection unit 45 corresponds to the surface of the metal plate 01, and detects the amount of protrusions or debris on the surfaces of both sides of the metal plate 01. If a metal plate 01 with protrusions is encountered, the equipment can be started to remove the protrusions on the surface of the metal plate 01. Specifically, the detection unit 45 can be a laser ranging detection device. When there are protrusions or debris on the surface of the metal plate 01, it can feedback information such as the position and amount of the protrusions or debris to determine whether it exceeds a predetermined value and whether it needs to be removed. The detection unit 45 can also be replaced by other devices with equivalent functions that can be easily thought of by technicians in this field.

[0095] In summary, when used, this application includes the following steps:

[0096] First, the translation mechanism is used to drive the cleaning unit 4 to move along the arrangement direction of the metal plates 01, and the detection unit 45 is used to detect the protrusions on the surface of each metal plate 01;

[0097] For a metal plate 01 with a protrusion (exceeding a predetermined value), the translation mechanism drives the cleaning unit 4 to move to the corresponding position, and then the lifting mechanism drives the cleaning unit 4 to move along the height direction of the metal plate 01. During this process, the inclined scraper 43 can adapt to the thickness of the metal plate 01 and adhere to the surface of the metal plate 01 until it is lifted to the upper part of the metal plate 01. Then, the inclined scraper 43 moves downward. Due to the locking of the non-return lock 421, it can remove the protrusion on the surface of the metal plate in a fixed posture;

[0098] When the inclined scraper 43 descends and removes the protrusions on the metal plate surface, the abutting protrusions at both ends of the vibration bracket 44 engage with the staggered vibration racks 34 on both sides thereof, generating a translational motion, which is intended to generate a lateral movement during the downward movement to cut the protrusions;

[0099] After the current metal plate 01 is processed, the non-return lock 421 can be retracted by the reset unit 422, and the reset torsion spring drives the inclined scraper 43 to rotate relatively, so as to adapt to the subsequent metal plate 01 and perform corresponding scraping work.

[0100] In a preferred embodiment, the present application can be used to scrape the protrusions on the surface of the cathode copper plate produced by electrolysis. After the reaction of each cathode plate 01 in the electrolytic cell is completed, it is lifted by a trolley into the frame 1 in the present application, and the frame 1 is arranged before the copper plate de-plate station to clean the protrusions on the surface of the copper plate before the copper plate is demolded from the metal plate 01 to avoid affecting the subsequent quality inspection process and packaging process.

[0101] In another preferred embodiment, the present application can be used for cast or heat-treated steel plates or aluminum plates, etc. After the plates are demolded, they are transferred to the frame 1 for equidistant arrangement, and then the amount of protrusions or debris on the surface of the metal plate 01 is detected by the detection unit 45, and then the protrusions, debris or bubbles on the surface are scraped and cleaned.

[0102] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0103] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0104] In addition, "plurality" means two or more.

[0105] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
