Technical Field

[0001] This application relates to the technical field of auxiliary devices for steel plate cleaning and grinding brushes, and in particular to a flipping device for steel plate cleaning and grinding brushes. Background Technology

[0002] In the field of steel plate processing, processes such as cleaning, grinding, or rust removal often require double-sided treatment of the steel plates. Traditionally, one side of the steel plate is processed first, then it is physically flipped manually or using auxiliary lifting equipment to process the other side. This flipping method is labor-intensive and inefficient. Furthermore, existing automated flipping equipment often uses grippers or suction cups to fix the steel plates, which lacks positioning stability during high-speed rotation or continuous operation, posing a risk of detachment. Additionally, traditional flipping devices are often only suitable for steel plates of a single length, exhibiting poor adaptability to different sizes and requiring cumbersome adjustments. Summary of the Invention

[0022] Example 1 Reference Figures 1-7 The first embodiment of this application provides a flipping device for cleaning abrasive brushes on steel plates, comprising: The support plate 10 has annular positioning rings 20 sleeved on the outer walls of both ends along the first direction, and a clearance groove 11 is provided through the middle of the support plate 10. The positioning rings 20 are also connected to a rotation drive assembly 30 so that the support plate 10 can be rotated in the circumferential direction. The support plate 10 has a plate-like structure, having a first end and a second end opposite to each other along a first direction, and a first side and a second side opposite to each other along a second direction. The first direction and the second direction are perpendicular to each other in the horizontal plane. Figure 1 As shown, X represents the first direction and Y represents the second direction. The inner diameter of the positioning ring 20 matches the outer walls at both ends of the bearing plate 10 in the first direction, and is fixedly sleeved onto the outer walls at both ends of the bearing plate 10 by interference fit or welding. The positioning ring 20 is used to rotatably support the bearing plate 10 on the external frame and transmit rotational torque. The clearance groove 11 is an elongated through hole extending along the second direction, penetrating the upper and lower surfaces of the bearing plate 10. The width of the clearance groove 11 along the first direction is greater than the width of the steel plate 100 to be processed, and the length of the clearance groove 11 along the second direction is greater than the length of the steel plate 100 to be processed, so as to ensure that the steel plate can pass through the bearing plate 10 vertically without obstruction. The rotary drive is fixedly installed on the external frame, and its power output end is mechanically connected to the outer wall of the positioning ring 20. The rotary drive assembly 30 is used to drive the positioning ring 20 to rotate around its own axis, thereby causing the bearing plate 10 to rotate 180° or 360° circumferentially.

[0023] Placement units 40, two placement units 40 are arranged along a second direction within the clearance groove 11. The placement units 40 are used to place the steel plate 100 to be processed. The two placement units 40 are movable in directions that bring them closer together or further apart, so that the steel plate 100 to be processed can move through the clearance groove 11 to the other side of the support plate 10. Each of the two placement units 40 includes a horizontal bearing surface for supporting the steel plate 100 to be processed. The two placement units 40 are arranged opposite each other in the internal space of the clearance groove 11 along the second direction.

[0024] The clamping assembly includes a flipping member 63, the first end of which is hinged to the support plate 10, and the second end of which is hinged to a clamping member 70. The clamping member 70 can be flipped around the first and second ends of the flipping member 63 so that one side wall of the clamping member 70 can be engaged with one side wall of the placement unit 40 to clamp the steel plate 100 to be processed.

[0025] The flipping component 63 is a rigid rod or plate. In this embodiment, for example... Figure 1 As shown, the flipping member 63 is a plate. The first end of the flipping member 63 is hinged to a hinge support provided on the side of the bearing plate 10 via a first hinge axis, meaning the flipping member 63 can swing about the first hinge axis in a vertical plane. The clamping member 70 is a rigid clamping body with multiple side walls. The clamping member 70 is hinged to the second end of the flipping member 63 via a second hinge axis, meaning the clamping member 70 can rotate about the second hinge axis relative to the flipping member 63. The rotation of the flipping member 63 about the first hinge axis and the rotation of the clamping member 70 about the second hinge axis are independent of each other, and their planes of motion are parallel or coincident. Through the combination of the two rotations, the clamping member 70 can select one of its multiple side walls to face the steel plate 100 to be processed, and make that side wall form a clamping engagement with the corresponding side wall of the placement unit 40. The clamping member 70 has at least two working postures. In the first posture, the bottom sidewall of the clamping member 70 engages with the upper surface of the placement unit 40 to clamp the steel plate; in the second posture, the upper sidewall of the clamping member 70 engages with the lower surface of the placement unit 40 to clamp the steel plate.

[0026] In this embodiment, the flipping device is used to support the steel plate to be processed. The specific brush or cleaning structure is not included in the flipping device of this embodiment. The specific cleaning or brushing structure can use existing equipment or be manually cleaned and brushed. According to the width dimension of the steel plate 100 to be processed along the second direction, the distance between the two placement units 40 is adjusted to be slightly larger than the width of the steel plate by driving them to move towards or away from each other along the second direction. At this time, the steel plate 100 to be processed is placed horizontally on the two placement units 40, with the steel plate 100 to be processed located directly above the clearance groove 11 of the support plate 10. Then, the clamping member 70 is moved by manual or mechanical means to bring it closer to the steel plate 100 to be processed. Next, according to the thickness of the steel plate and the clamping requirements, the clamping member 70 is adaptively flipped around the second hinge axis of its second end. Then, by continuing to drive the flipping member 63 or the clamping member 70, the selected side wall of the clamping member 70 and the corresponding upper surface of the placement unit 40 work together to tightly clamp and fix the steel plate 100 to be processed from both the top and bottom. Maintain the relative stability of the steel plate 100 to be treated. Then, the steel plate 100 to be treated can be brushed and cleaned manually or by using existing cleaning and brushing equipment. There may be cleaning dead corners in the area where the clamping member 70 contacts the steel plate 100 to be treated. Since this area is small, it can be handled manually. Similarly, when the other side of the steel plate 100 to be treated needs to be treated, after releasing the clamping action of the clamping member 70, this area can be treated first before flipping it over. When the other side of the steel plate 100 needs to be processed, the clamping action of the clamping member 70 is first released. Then, the clamping member 70 is controlled to flip around the first and second ends of the flipping member 63, so that the clamping member 70 is flipped to be located below the support plate 10 and locked. Then, the two placement units 40 are driven to move away from each other, so that the steel plate 100 to be processed falls onto the clamping member 70 below. Then, the two placement units 40 are driven to move closer to each other, driving the positioning ring 20 to rotate, so that the support member rotates 180°. The other side of the steel plate 100 to be processed is then processed manually or by a cleaning and brushing device at the same station. Through the cooperation of the rotation drive assembly 30, the positioning ring 20 and the support plate 10, the steel plate can be automatically driven to flip around the circumference, replacing manual flipping or hoisting flipping, improving flipping efficiency and avoiding the risk of personnel injury that may be caused by manual operation.

[0027] Example 2 Based on Embodiment 1, this embodiment provides a flipping device for cleaning abrasive brushes on steel plates, including: a rotary drive assembly 30 including a support ring 32, a gear ring 31, and a rotary motor 34; two support rings 32 are arranged along a first direction and are sleeved on the periphery of a positioning ring 20; the gear ring 31 is circumferentially disposed on the outer wall of the positioning ring 20; the rotary motor 34 is disposed on the outer wall of the support ring 32; a first gear 33 is sleeved on the output shaft of the rotary motor 34, and the first gear 33 is used to mesh with the gear ring 31.

[0028] Specifically, two support rings 32 are fixedly installed on the external frame and arranged at intervals along the first direction. Each support ring 32 is a circular ring structure with an inner diameter larger than the outer diameter of the positioning ring 20 to accommodate the positioning ring 20. The two support rings 32 together form a fixed support base for the flipping of the bearing plate 10. The toothed ring 31 is either an internal toothed ring 31 or an external toothed ring 31, and in this embodiment, an external toothed ring 31 is preferred. The toothed ring 31 is coaxially fixed to the outer wall of the positioning ring 20 by welding or bolting, and its axis coincides with the axis of the positioning ring 20. The two support rings 32 are arranged along the first direction and fitted around the periphery of the positioning ring 20, which not only provides a stable mounting base for the rotary motor 34, but also forms a double-point support for the positioning ring 20, reducing the radial runout and axial movement of the bearing plate 10 during the flipping process and improving the flipping stability. The rotary motor 34 is installed on the external support ring 32, rather than rotating with the bearing plate 10, which simplifies the electrical wiring and reduces the moment of inertia.

[0029] Optionally, the inner wall of the support ring 32 is provided with a first groove extending in the circumferential direction, and the outer wall of the positioning ring 20 is provided with a second groove extending in the circumferential direction. The first groove and the second groove are engaged to form a ball groove, and the ball groove is filled with a ball body 21.

[0030] Specifically, the first groove is located on the inner wall of the support ring 32, and is formed along the entire circumference as an annular groove with an arc or V-shaped cross-section. The second groove is an annular groove that corresponds to the position and matches the shape of the first groove. Multiple ball bodies 21 are filled in the ball groove at even intervals or in a fully packed manner. The ball bodies 21 simultaneously form rolling contact with the groove walls of the first and second grooves. The rolling contact of the ball bodies 21 replaces the sliding friction between the support ring 32 and the positioning ring 20, which greatly reduces the resistance when the bearing plate 10 is flipped, thereby reducing the load and energy consumption of the rotary motor 34.

[0031] Optionally, the placement unit 40 includes a placement plate 41 extending in a first direction, an inner wall of the clearance groove 11 being provided with a guide groove 44 extending in a second direction, and an outer wall of the placement plate 41 being provided with a guide block 45, which is used to cooperate with the guide groove 44 and can move along its extension direction.

[0032] Specifically, the main body of each placement unit 40 is a long strip-shaped plate structure extending along a first direction, with its length direction parallel to the first direction. The placement plate 41 is used to directly support the steel plate 100 to be processed. On the two opposite inner sidewalls of the clearance groove 11 along the second direction, one or more straight guide grooves 44 extending horizontally along the second direction are respectively provided. The cross-sectional shape of the guide groove 44 is T-shaped, dovetail-shaped, or rectangular. Through the sliding engagement of the guide block 45 and the guide groove 44, the degrees of freedom of the placement plate 41 other than the second direction are strictly restricted, ensuring that the two placement plates 41 always remain parallel and coplanar when they approach or move away from each other, avoiding the steel plate from being unable to be placed horizontally or being unstable due to skew.

[0033] Optionally, the two placement units 40 are also connected to a lateral drive assembly 50, which includes a rack 51, a lateral motor, and a second gear 52. The placement unit 40 also includes a movable plate 43 and a connecting rod 42. The support plate 10 has a movable groove 12 that runs through the first direction. The movable plate 43 is disposed in the movable groove 12 and can move in the second direction. The movable plate 43 and the placement plate 41 are connected to each other by at least one connecting rod 42. One end of the movable plate 43 passes through the movable groove 12 and is connected to one of the racks 51. The lateral motor is connected to the outer wall of the support plate 10. The second gear 52 is sleeved on the output shaft of the lateral motor and meshes with the racks 51 connected to the two placement units 40 simultaneously.

[0034] Specifically, two through slots extending along a first direction are formed on the support plate 10, and these through slots extend along a second direction. Each placement unit 40 also includes a movable plate 43, which is disposed outside the support plate 10 and can move along the movable slot 12 in the second direction. One end of the movable plate 43 extends into the interior of the support plate 10 through the movable slot 12. The placement plate 41 and the movable plate 43 are fixedly connected by at least one connecting rod 42, for example, two connecting rods 42 arranged at intervals along the first direction, to achieve synchronous movement of the placement plate 41 and the movable plate 43. A transverse motor (not shown in the figures) is fixedly mounted on the outer wall of the support plate 10, and a second gear 52 is fixedly sleeved on its output shaft. The second gear 52 is located between two racks 51 and meshes with both racks 51 simultaneously. When the transverse motor rotates forward, the second gear 52 drives the two racks 51 to move in opposite linear directions, thereby causing the two placement units 40 to move closer to each other; when the transverse motor rotates in reverse, the two racks 51 move in opposite linear directions, causing the two placement units 40 to move away from each other. By using a second gear 52 to simultaneously drive two racks 51, it is possible to ensure that the two placement units 40 move in a strictly symmetrical manner relative to the centerline of the support plate 10. This ensures that the steel plate is always positioned in the center of the support plate 10, which is beneficial for maintaining the center of gravity balance during subsequent flipping and reduces eccentric torque.

[0035] Optionally, the placement plate 41 has a first placement surface 411 and a second placement surface 412, the first placement surface 411 and the second placement surface 412 protruding from the upper and lower surfaces of the support plate 10 respectively; both the first placement surface 411 and the second placement surface 412 are provided with a limiting protrusion 413 extending in a first direction, and the limiting protrusions 413 of the two placement units 40 can form a limiting structure in a second direction.

[0036] Specifically, the first placement surface 411 is located above the support plate 10 and is used to support the steel plate to be processed; the second placement surface 412 is located below the support plate 10 and can support the steel plate 100 to be processed falling through the clearance groove 11 after the clamping member 70 is rotated 180°. Both are higher than the corresponding surfaces of the support plate 10 to avoid interference between the steel plate 100 to be processed and the support plate 10. When the two placement units 40 are close to each other to match the width of the steel plate, the limiting protrusion 413 on the left placement plate 41 and the limiting protrusion 413 on the right placement plate 41 together form an existing structure that limits the steel plate 100 along the second direction, restricting the two sides of the steel plate 100 to be processed within it and preventing the steel plate from sliding along the second direction during the rotation process. Furthermore, the two limiting protrusions 413 can, to a certain extent, automatically center the steel plate 100. When the steel plate 100 is slightly tilted, the two limiting protrusions 413 move synchronously with the two placement plates 41 in a direction closer to each other, pushing the slightly tilted steel plate 100 to move and automatically centering it. This ensures that the distances from the two edges of the steel plate 100 to the axes of symmetry of the two limiting protrusions 413 are equal. The first placement surface 411 and the second placement surface 412 correspond to the two work positions before and after the bearing plate 10 is flipped, respectively, ensuring stable support for the steel plate before and after flipping, eliminating the need to readjust the position of the placement plates 41 and improving processing continuity. The limiting structure along the second direction formed by the limiting protrusions 413 effectively constrains the steel plate's degree of freedom in the width direction, complementing the vertical clamping of the clamping assembly. This achieves full degree of freedom constraint on the steel plate in both the horizontal and vertical planes, significantly enhancing the positional stability of the steel plate during flipping.

[0037] Optionally, the outer wall of the support plate 10 is provided with two fixing blocks 60, and the first end of the flipping member 63 is connected to the two fixing blocks 60 through a rotating shaft 61. The fixing block 60 is provided with a first motor 62 for driving the rotating shaft 61 to rotate.

[0038] Specifically, two fixed blocks 60 are spaced apart along a first direction on the outer wall of the support plate 10. Shaft holes are machined into the fixed blocks 60. A rotating shaft 61 passes through the shaft holes of both fixed blocks 60 and is fixedly connected to the first end of the flipping component 63, for example, by keying or welding. The rotating shaft 61 can rotate freely relative to the fixed blocks 60. A first motor 62 is fixedly mounted on the outside of one of the fixed blocks 60 or on the support plate 10. Its output shaft can be directly connected to one end of the rotating shaft 61 via a coupling or via gear transmission. After the first motor 62 starts, it drives the rotating shaft 61 to rotate, causing the rotating component 63 to swing around its first end, i.e., the axis of the rotating shaft 61. By driving the rotating component 63 to swing via the first motor 62, manual operation is eliminated, achieving automated control of the clamping assembly, which is beneficial for integration into a fully automated production line. The motor drive can precisely control the swing angle of the rotating component 63, thereby controlling the clamping force of the clamping component 70 on the steel plate, avoiding damage to the steel plate due to excessive pressure or loosening due to insufficient pressure.

[0039] Optionally, the clamping member 70 includes two side guards 71 ​​extending along the second direction. One end of the two side guards 71 ​​is rotatably connected to the flipping member 63. The flipping member 63 is provided with a second motor 64, which is used to drive the clamping member 70 to flip around the second end of the flipping member 63.

[0040] Specifically, two side guard rods 71 ​​are spaced apart along a first direction, and each side guard rod 71 extends along a second direction. The two side guard rods 71 ​​together form the main frame of the clamping member 70. One end of each side guard rod 71 near the second end of the flipping member 63 is rotatably connected to the second end of the flipping member 63 via a hinge shaft. That is, the side guard rod 71 can rotate relative to the flipping member 63 around the hinge shaft. The second motor 64 is fixedly mounted on the flipping member 63, for example, on the side or inside of the flipping member 63. Its output shaft is connected to the hinge shaft of the side guard rod 71 through a transmission mechanism, such as a worm gear or gear pair, or is directly coaxially fixed to the hinge shaft of one of the side guard rods 71. After the second motor 64 is started, it drives the side guard rod 71 to rotate around the second end of the flipping member 63, thereby changing the angle and posture of the clamping member 70 relative to the placement unit 40 to select different side walls to contact the steel plate 100 to be processed.

[0041] Optionally, the two ends of the side guard rod 71 are respectively provided with abutment units 90. The abutment unit 90 includes an abutment rod 91, a pull rod 92 and a compression spring 93. The abutment rod 91 extends along the second direction, and at least two pull rods 92 are arranged along the second direction. One end of the pull rod 92 is connected to the side guard rod 71, and the other end is provided with a limit block 94. The abutment rod 91 has a guide hole that matches the pull rod 92 and a limit groove 911 that cooperates with the limit block 94. The compression spring 93 is sleeved on the pull rod 92 and is located between the side guard rod 71 and the abutment rod 91. The limit groove 911 is located on the side of the abutment rod 91 away from the side guard rod 71. The width of the limit groove 911 is greater than the width of the guide hole, and the depth of the limit groove 911 is greater than the height of the limit block 94.

[0042] Specifically, the abutment rod 91 is a strip-shaped rod extending along the second direction, located on the side of the side guard rod 71 near the steel plate. The abutment rod 91 is used to directly contact the surface of the steel plate. Each abutment unit 90 is provided with at least two pull rods 92, which are arranged along the second direction. One end of each pull rod 92 is fixedly connected to the side guard rod 71, and the other end is a free end with a limiting block 94. The limiting block 94 can be a circular or square protrusion, and its outer diameter or side length is greater than the diameter of the main body of the pull rod 92. On the abutment rod 91, corresponding to the position of each pull rod 92, a guide hole penetrating the thickness direction of the abutment rod 91 is provided. The diameter of the guide hole matches the diameter of the main body of the pull rod 92. On the side of the abutment rod 91 away from the side guard rod 71, that is, the side near the steel plate, a limiting groove 911 coaxial with the guide hole is provided. The width of the limiting groove 911 is greater than the width of the guide hole, and the depth of the limiting groove 911 is greater than the height of the limiting block 94. The pull rod 92 is passed through the guide hole, causing the limiting block 94 to fall into the limiting groove 911. Since the width of the limiting groove 911 is greater than that of the limiting block 94, the limiting block 94 can move freely a certain distance within the limiting groove 911. A compression spring 93 is fitted onto the pull rod 92, with one end abutting against the side guard rod 71 and the other end abutting against the abutting rod 91, providing elastic force to move the abutting rod 91 away from the side guard rod 71. When the abutting rod 91 is pushed towards the side guard rod 71, the pull rod 92 slides relative to the guide hole, and the limiting block 94 moves towards the side guard rod 71; when the compression spring 93 pushes the abutting rod 91 away from the side guard rod 71, the limiting block 94 contacts the bottom wall of the limiting groove 911, serving as an anti-disengagement limiting element. The abutting rod 91 is connected to the side guard rod 71 via the compression spring 93. When the clamping member 70 clamps the steel plate, the abutting rod 91 is in elastic contact with the surface of the steel plate. Even if there are minor unevenness or thickness tolerances on the surface of the steel plate, the elastic structure can automatically compensate for them, avoiding indentations or scratches on the steel plate surface caused by rigid clamping. Similarly, when the steel plate to be tested falls onto the clamping member 70, the abutment unit 90 can also act as a buffer, absorbing some of the kinetic energy of the falling steel plate 100.

[0043] Optionally, the clamping member 70 also includes a locking rod 72, which extends along a first direction and is connected to the first ends of the two side guard rods 71 ​​away from the flipping member 63. The upper and lower ends of the bearing plate 10 are respectively provided with locking units 80 for cooperating with the locking rod 72. The locking unit 80 includes a base 81, a locking rod 85, a locking spring 84, a baffle 82, a linkage pin 86, a linkage plate 87, a linkage column 88, and a linkage spring 89. The base 81 is disposed on the support plate 10. The base 81 has a positioning hole that extends in the second direction. The locking rod 85 passes through the positioning hole. The locking rod 72 has a locking hole 721 that can cooperate with the locking rod 85. The base 81 has a spring groove 83 that communicates with the positioning hole. The baffle 82 is connected to the locking rod 85 and is located in the spring groove 83. The locking spring 84 is located between the baffle 82 and the inner wall of the spring groove 83 on the side away from the locking rod 72. The base 81 is provided with a connecting groove 841 located between the spring groove 83 and the bearing plate 10. The connecting groove 841 and the spring groove 83 are connected to each other through a connecting hole. The linkage column 88 is disposed in the connecting groove 841. The linkage plate 87 is sleeved on the linkage column 88 and can move along the linkage column 88. The linkage spring 89 is disposed between the linkage plate 87 and the bottom wall of the connecting groove 841. One end of the linkage pin 86 is connected to one side of the linkage plate 87. The other end of the linkage pin 86 can form a limiting structure with the through connecting hole and the baffle 82. The locking rod 72 can contact the other end of the linkage plate 87 so as to drive the linkage pin 86 to exit from the spring groove 83. The linkage plate 87 has an upwardly protruding flange 871. The flange 871 can form a limiting structure in the second direction with the locking rod 72.

[0044] Specifically, the locking rod 72 extends along the first direction, and its two ends are fixedly connected to the ends of the two side guard rods 71 ​​that are away from the first end of the flipping member 63. The locking rod 72 is a rod with a rectangular or circular cross-section and a locking hole 721 that runs through it along the second direction. At the upper and lower ends of the bearing plate 10, corresponding to the positions of the clamping member 70 before and after flipping, a locking unit 80 is respectively provided. The locking unit 80 cooperates with the locking rod 72 to lock the steel plate after the clamping member 70 clamps it, preventing accidental release during the flipping process.

[0045] The base 81 is fixedly mounted on the support plate 10 and has multiple internal chambers. A positioning hole extends through the base 81 along a second direction. When the locking rod 72 is in position, the axis of the positioning hole is coaxial with the locking hole 721 on the locking rod 72. The locking rod 85 slidably passes through the positioning hole, its front end can be inserted into the locking hole 721 of the locking rod 72, and its rear end extends out of the base 81 or is provided with a limiting part. The spring groove 83 communicates with the positioning hole and is a circular groove with a diameter larger than the positioning hole. The baffle 82 is fixedly sleeved on the locking rod 85 and located within the spring groove 83. The locking spring 84 is sleeved on the locking rod 85, one end abutting against the baffle 82, and the other end abutting against the inner wall of the spring groove 83 on the side away from the locking rod 72. The elastic force of the locking spring 84 tends to push the locking rod 85 towards the locking rod 72. The connecting groove 841 is located between the spring groove 83 and the support plate 10 and is a cavity connected to the spring groove 83 through a connecting hole. A linkage column 88 is vertically positioned within the connecting groove 841, with its axis along a third direction (vertical), serving as a guide column. A linkage plate 87 is fitted onto the linkage column 88 and can move up and down along it. The linkage plate 87 has a first end and a second end; the first end faces the connecting hole, and the second end faces the outside of the bearing plate 10. An upwardly protruding flange 871 is provided on the upper surface of the linkage plate 87. A linkage spring 89 is fitted onto the linkage column 88, located between the linkage plate 87 and the bottom wall of the connecting groove 841, and its elastic force tends to push the linkage plate 87 upward. One end of a linkage pin 86 is fixed to the first end of the linkage plate 87, and the other end extends towards the connecting hole and can pass through the connecting hole into the spring groove 83.

[0046] In the initial state, the linkage spring 89 lifts the linkage plate 87, and the linkage pin 86 passes through the connecting hole into the spring groove 83, and is located on the side of the baffle 82 facing the locking rod 72, that is, between the baffle 82 and the locking rod 72, thereby preventing the baffle 82 from moving towards the locking rod 72, that is, preventing the locking rod 85 from extending. When the locking rod 72 presses down on the second end of the linkage plate 87 from above, the linkage plate 87 overcomes the elastic force of the linkage spring 89 and moves downward, causing the linkage pin 86 to exit from the spring groove 83, releasing the obstruction to the baffle 82. At this time, the locking spring 84 can push the locking rod 85 to extend and insert into the locking hole 721. During the pressing down of the locking rod 72, the flange 871 on the linkage plate 87 can contact the side of the locking rod 72, forming a limiting structure along the second direction, ensuring that the locking rod 72 is accurately pressed in the correct position on the linkage plate 87 and preventing displacement. Similarly, the flange 871 can also prevent the clamping member 70 from separating from the locking rod 85 along the second direction. The locking rod 85 engages with the locking hole 721, automatically locking after the clamping member 70 is in position. Even if the motor is powered off or the hydraulic system fails, the locking mechanism can maintain the clamping state through its mechanical structure, greatly improving the safety of the flipping operation. When unlocking is required, external force is applied to the locking rod 85 to disengage it from the locking hole 721.

[0047] For example, the main process of using the flipping device of this application is as follows: S1. Perform reset and testing: The control system issues a command to confirm that the support plate 10 is in the initial horizontal position, at which time the first placement surface 411 faces upward.

[0048] Confirm that the clamping assembly is in the fully open state: the flipping part 63 is driven by the first motor 62 to swing upward to the maximum opening, the clamping part 70 is driven by the second motor 64 to swing back to the non-clamping posture, and the locking rod 72 disengages from the locking unit 80.

[0049] Confirm that the two placement units 40 are at maximum spacing.

[0050] S2. Adjust the spacing of the placement units by 40mm according to the width of the steel plate: The operator or upstream testing equipment inputs the width of the steel plate to be processed 100, i.e. the dimension along the second direction, into the control system.

[0051] The control system starts the horizontal motor. The horizontal motor drives the second gear 52 to rotate, and the second gear 52 simultaneously meshes with two racks 51, driving the two moving plates 43 to move synchronously in opposite directions or in a straight line along the moving groove 12.

[0052] The moving plate 43 drives the placement plate 41 to move via the connecting rod 42, and the guide block 45 at the bottom of the placement plate 41 slides smoothly along the guide groove 44 on the inner side wall of the clearance groove 11.

[0053] When the distance between the two placement plates 41 is slightly greater than the width of the steel plate, for example, 2-5 mm, the horizontal motor stops and the two placement plates 41 are locked in that position.

[0054] S3. Place the steel plate to be processed (100 mm): The loading robot or manual laborer places the steel plate 100 to be processed horizontally on the first placement surface 411 of the two placement units 40.

[0055] Since the first placement surface 411 protrudes from the upper surface of the support plate 10, a gap is formed between the steel plate and the support plate 10 to avoid interference.

[0056] The two sides of the steel plate fall between the limiting protrusions 413 extending in the first direction on the two placement plates 41, forming a preliminary limit in the second direction to prevent the steel plate from moving randomly in the width direction.

[0057] S4. Lateral clamping of the steel plate to be processed 100: The control system starts the horizontal motor, causing the two placement plates 41 to move a certain distance in a direction that brings them closer together, so that the limiting protrusions 413 above the placement plates 41 clamp and fix the two sides of the steel plate 100 to be processed.

[0058] S5. Clamping assembly flips and holds: The control system starts the first motor 62. The first motor 62 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the tilting component 63 to swing downward around its first end.

[0059] Simultaneously or slightly afterward, the control system activates the second motor 64. The second motor 64 drives the clamping member 70 to adaptively rotate around the second end hinge point of the flipping member 63, selecting the bottom wall of the clamping member 70 as the clamping working surface facing the steel plate.

[0060] The flipper 63 continues to swing downwards, bringing the bottom wall of the clamping member 70 close to the upper surface of the steel plate. At this time, the abutment unit 90 located at the end of the side guard rod 71 first contacts the steel plate: the abutment rod 91 elastically adheres to the surface of the steel plate under the action of the compression spring 93, multiple pull rods 92 are arranged along the second direction to ensure uniform force distribution, and the limiting block 94 provides anti-disengagement limitation within the limiting groove 911.

[0061] The flipper 63 continues to swing down to the preset position, and the bottom wall of the clamping member 70 mates with the first placement surface 411 of the placement unit 40, elastically clamping and fixing the steel plate from both the top and bottom. The stroke of the compression spring 93 compensates for the thickness tolerance of the steel plate, avoiding rigid pressure damage.

[0062] S6. Mechanical locking: When the clamping member 70 fully clamps the steel plate, the locking rod 72 connected to the ends of the two side guard rods 71 ​​moves down accordingly.

[0063] The locking lever 72 contacts the second end of the linkage plate 87 in the locking unit 80, that is, the end away from the linkage pin 86, and pushes the linkage plate 87 downward against the elastic force of the linkage spring 89. The linkage plate 87 slides downward along the linkage post 88.

[0064] As the linkage plate 87 moves downward, the linkage pin 86 fixed to the first end of the linkage plate 87 retracts from the spring groove 83.

[0065] After the baffle 82 is no longer blocked by the linkage pin 86, the locking spring 84 pushes the baffle 82 and the locking rod 85 to move towards the locking rod 72. The locking rod 85 extends along the positioning hole and inserts into the locking hole 721 on the locking rod 72.

[0066] At the same time, the upward-protruding flange 871 on the linkage plate 87 contacts the side of the locking rod 72, forming a limiting structure along the second direction, ensuring that the locking rod 72 will not move arbitrarily along the second direction, causing the locking rod 85 to separate from the locking hole 721.

[0067] At this point, the mechanical self-locking is completed, and even if the first motor 62 and the second motor 64 are de-energized, the clamping assembly cannot be opened automatically, ensuring safety during the flipping process.

[0068] S7, First cleaning brush: Once the steel plate is in its initial horizontal position and is compressed, the cleaning and abrasive devices above, such as brush rollers and spray heads, can first clean or abrade the upper surface of the steel plate.

[0069] During the processing, since the distance between the two placement plates 41 is greater than the width of the steel plate, and the limiting protrusion 413 only restricts lateral movement, the cleaning fluid and grinding debris can be smoothly discharged from the clearance groove 11 and both sides.

[0070] S8, bearing plate 10 flips: First, the locking unit 80 is released from its locking state, causing the locking rod 85 to retract from the locking hole 721. Then, the first motor 62 and the second motor 64 drive the clamping member 70 to flip to the underside of the carrier member. As the flipping member 63 flips downward to its position, the locking rod 85 engages with the locking unit 80 at the lower end of the carrier member to complete the locking. Then, the horizontal motor is controlled to increase the distance between the two placement plates 41. When the distance increases to a value greater than the width of the steel plate 100 to be processed, the steel plate 100 falls onto the clamping member 70 through the clearance groove 11. After the steel plate 100 falls onto the clamping member 70 through the clearance groove 11, the horizontal motor is controlled to move the two placement plates 41 toward each other, causing the limiting protrusions 413 on the two placement plates 41 to clamp the steel plate 100 to be processed.

[0071] Then the carrier plate 10 is flipped, and the rotation drive assembly 30 is started.

[0072] The rotary motor 34 starts, and the first gear 33 on its output shaft rotates, driving the gear ring 31 on the outer wall of the positioning ring 20 to rotate. The gear ring 31 drives the positioning ring 20 to rotate around its axis.

[0073] When the positioning ring 20 rotates, the ball body 21 between the first groove on the inner wall of the support ring 32 and the second groove on the outer wall of the positioning ring 20 provides rolling support, significantly reducing frictional resistance.

[0074] The positioning ring 20 drives the bearing plate 10 and all its components, such as the placement unit 40, the clamping assembly, and the clamped steel plate 100 to be processed, to rotate 180° around the first direction axis.

[0075] During the flipping process, since the steel plate is firmly clamped and the distance between the two placement plates 41 matches the width of the steel plate, the steel plate does not move relative to the bearing plate 10.

[0076] S9, Second cleaning brush: After the bearing plate 10 is rotated 180°, the original bottom surface of the steel plate faces upward and is fully exposed to the space above.

[0077] The cleaning and brushing device is restarted to clean or brush the second side of the steel plate. Because the clearance groove 11 passes through the support plate 10, and the second placement surface 412 also protrudes from the lower surface of the support plate 10 (becoming the upper surface after flipping), processing tools or cleaning media can approach the steel plate surface without obstruction. After cleaning and brushing both sides of the steel plate 100 to be treated, it can be unloaded.

[0078] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
