Without 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 those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0019] Please refer to Figure 1-9 , the present invention discloses a scraping device for the surface of a metal plate, including: Frame 1, the frame 1 is used to place the metal plate 01, and a support part 2 for carrying the tabs of the metal plate 01 is arranged in parallel on the frame 1, and the metal plates 01 are arranged at equal intervals in the frame 1; Moving part 3, the number of the moving parts 3 is two groups, and the two groups of the moving parts 3 are movably arranged in the support part 2; Cleaning part 4, the cleaning part 4 is arranged between the two groups of the moving parts 3, and the moving part 3 is used to drive the cleaning part 4 to move along the arrangement direction of the metal plate 01 and clean and scrape the surface of the metal plate 01; Specifically, the cleaning part 4 includes a cleaning scraping table 41, a hollow groove 411 for the metal plate 01 to pass through is arranged on the cleaning scraping table 41, and scraper brackets 42 distributed on both sides of the hollow groove 411 are also arranged on the cleaning scraping table 41, and inclined scrapers 43 in contact with the metal plate 01 are arranged on the two groups of scraper brackets 42. As Figure 1 shown, the two groups of inclined scrapers 43 are arranged obliquely downward, and are used to scrape the protrusions on the surface of the metal plate 01 during the process of the cleaning scraping table 41 running from top to bottom; 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 to lock the two groups of inclined scrapers 43 when the metal plate 01 leaves between the two inclined scrapers 43, so that the protrusions on the surface of the metal plate 01 are scraped off by the inclined scrapers 43.

[0020] It should be further explained that the moving part 3 includes a translation mechanism and a lifting mechanism; The translation mechanism is operated to drive the cleaning part 4 to move along the arrangement direction of the metal plates 01; The lifting mechanism is operated to drive the cleaning part 4 to move along the height direction of the metal plate 01.

[0021] In a preferred embodiment, two groups of scraper brackets 42 are slidably arranged on the cleaning scraper platform 41, and a vibration groove for horizontal movement of the scraper bracket 42 is provided on the cleaning scraper platform 41, and a limit block located above the vibration groove is provided on the scraper bracket 42, wherein the limit block is used to support the scraper bracket 42 to be able to move horizontally along the vibration groove; A vibration bracket 44 is connected between the two groups of scraper brackets 42, and abutment protrusions are arranged on both sides of the vibration bracket 44; The two sets of lifting mechanisms are provided with vibration racks 34 corresponding to the abutment protrusions located on both sides of the vibration bracket 44; 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 through the cooperation between the vibration protrusions and the abutment protrusions during the cleaning and scraping process of the cleaning part 4.

[0022] In the above structure, when the cleaning part 4 is running, the cleaning scraper 41 is lifted up by the lifting mechanism, and the inclined scraper 43 arranged inside it is fitted 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. In this process, due to the setting of the vibration bracket 44, the abutting protrusions at both ends of the vibration bracket 44 are engaged with the vibration racks 34 staggered on both sides thereof, which will produce a translational action, aiming to change the cutting path in the process of moving downward cutting, so that the inclined scraper 43 changes from vertical cutting to oblique cutting. Compared with vertical cutting, the cutting force is dispersed during oblique cutting, the wear of the tool is more uniform, the local overload of the tool is reduced, thereby extending the service life of the tool, and 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.

[0023] In another preferred embodiment, a third driving unit for driving the vibration rack 34 to move up and down is further provided in the two sets of the lifting mechanisms; The third driving unit is used to drive the two sets of vibration racks 34 to move up and down, so as to drive the vibration bracket 44 to generate translational vibration through the intersecting vibration protrusions arranged thereon, aiming to make a lateral cutting action when the inclined scraper 43 contacts the protrusions on the surface of the metal plate, and to cut and scrape the stubborn protrusions as the cleaning table 41 continues to descend.

[0024] It is easy to think that the translation mechanism includes a first lead screw 31 and a first driving unit 32 for driving the first lead screw 31 to rotate; The first lead screw 31 is arranged on both sides of the metal plate 01 along the arrangement direction of the metal plate 01; The first lead screw 31 is rotatably arranged in the support part 2.

[0025] Furthermore, the lifting mechanism includes a lifting seat rotatably connected to the first lead screw 31; A second driving unit 33 and a second lead screw 331 arranged at its output end are provided on the lifting seat, and a guide rail 332 is also provided on the lifting seat; Connection holes 412 adapted to the second lead screw 331 and the guide rail 332 are provided at both ends of the cleaning table 41; The lifting mechanism is used to drive the cleaning table 41 to move along the height direction of the metal plate 01 through the engagement of the second lead screw 331 and the connection holes 412.

[0026] It should be added that both the first driving unit 32 and the second driving unit 33 are servo motors. The above translation mechanism and lifting mechanism are conventional technical means that are easy to think of by those skilled in the art, and 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.

[0027] In a preferred embodiment, in order to avoid the situation that the metal plate 01 shakes during the above cutting process, a locking part adapted to the ear of the metal plate 01 is provided on the support part 2; The locking part includes two hinge seats 21, and L-shaped hinge rods 22 are arranged opposite to the two hinge seats 21; A lock plate 23 for abutting against the metal plate 01 is rotatably arranged at the top end of the L-shaped hinge rod 22; A bearing plate 24 in contact with the metal plate 01 is provided at the bottom end of the L-shaped hinge rod 22.

[0028] When each metal plate 01 is placed in the corresponding locking part of the support part 2, the bearing plate 24 contacts the lug of the metal plate 01. At the same time, due to its own weight, the L-shaped hinge rod 22 can be pressed down to rotate, so that the rotatably arranged lock plate 23 relatively abuts against both sides of the lug, realizing the 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 from affecting the scraping efficiency and product quality.

[0029] Furthermore, it should be noted that the one-way locking member includes a connecting ring arranged at the top end of the scraper support 42; A connecting shaft 431 adapted to the connecting ring is arranged on the inclined scraper 43, and one-way cogs are arranged on the connecting shaft 431; A check lock 421 that abuts against the one-way cogs is arranged in the connecting ring; The check lock 421 is used to make the inclined scraper 43 rotatable in one direction.

[0030] Furthermore, a return torsion spring for driving the connecting shaft 431 to reset is also arranged in the connecting ring; A reset unit 422 for driving the check lock 421 to contract is also arranged in the connecting ring; The reset unit 422 is used to drive the check lock 421 to retract to unlock the one-way cogs, and drive the inclined scraper 43 to rotate relatively through the return torsion spring to adapt to the subsequent metal plate 01.

[0031] Through the above structural settings, since the two groups of inclined scrapers 43 are arranged obliquely downward, during the lifting process of the inclined scraper 43, the inclined scraper 43 can adapt to metal plates 01 of different thicknesses and fit with the surface of the metal plate 01 until it is lifted to the top of the metal plate 01. Then, the inclined scraper 43 moves downward. Due to the locking of the check lock 421, it can remove the protrusions on the surface of the metal plate in a fixed posture; After the treatment of the current metal plate 01 is completed, the check lock 421 can be contracted through the reset unit 422, and the inclined scraper 43 is driven to rotate relatively by the return torsion spring to wait for adapting to the subsequent metal plate 01.

[0032] Finally, it should be noted that as Figure 9 shown, a detection unit 45 is arranged on the cleaning and scraping table 41, and the detection unit 45 is used to detect the protrusions on the surface of the metal plate 01; Specifically, since the positions of the metal plates 01 are fixed, the user can control the position of the cleaning table 41 through the servo motor to make the detection end of the detection unit 45 correspond to the surface of the metal plate 01, and detect the amount of protrusions or debris on both sides of the metal plate 01. In case of a metal plate 01 with protrusions, the device 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 the amount of protrusions 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 are easily conceivable by those skilled in the art.

[0033] In summary, when the present application is in use, it includes the following steps: First, the translation mechanism operates to drive the cleaning part 4 to move along the arrangement direction of the metal plates 01, and the detection unit 45 detects the protrusions on the surfaces of the metal plates 01; For the metal plate 01 with protrusions (exceeding the predetermined value), after the translation mechanism drives the cleaning part 4 to move to the corresponding position, the lifting mechanism drives the cleaning part 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 fit 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 being locked by the check lock 421, it can remove the protrusions on the surface of the metal plate in a fixed posture; During the process of the inclined scraper 43 descending and removing the protrusions on the surface of the metal plate, the abutting protrusions at both ends of the vibration bracket 44 engage with the vibration racks 34 arranged alternately on both sides thereof, generating a translational movement, aiming to generate a lateral movement during the downward cutting to cut the protrusions; After the current metal plate 01 is processed, the reset unit 422 can contract the check lock 421, and drive the inclined scraper 43 to rotate relative to each other by the reset torsion spring, waiting to adapt to the subsequent metal plates 01 and perform corresponding removal work.

[0034] In a preferred embodiment, the present application can be used to scrape the protrusions on the surface of the cathode copper plates produced by the electrolysis method. After each cathode plate 01 is reacted in the electrolytic cell, it is hoisted to the frame 1 in the present application by a trolley, and the frame 1 is arranged before the copper plate stripping station to clean the protrusions on the surface of the copper plate before the copper plate is stripped from the metal plate 01, so as to avoid affecting the subsequent quality inspection process and packaging process.

[0035] In another preferred embodiment, the present application can be used for casting or heat-treating steel plates or aluminum plates, etc. After the plate is demolded, it is transferred to the frame 1 and arranged at equal intervals, and then the detection unit 45 is used to detect the amount of protrusions or foreign matters on the surface of the metal plate 01, and then the protrusions, foreign matters or bubbles on the surface are scraped and cleaned up.

[0036] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0037] In addition, if there are descriptions such as "first", "second", etc. involved 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 quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0038] In addition, "a plurality" means more than two.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
