[0016] The present invention 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. All other embodiments obtained by ordinary technicians in this field based on the present invention are within the scope of protection of the present invention.

[0017] The utility model provides a plate turning machine for double-sided inspection of steel plates, comprising a frame 1 and a turning mechanism, wherein the frame is arranged in a horizontal direction, and a conveying mechanism is provided on the upper side of the frame for conveying the steel plate 2 to the bottom of the turning mechanism; the turning mechanism is arranged on one side of the frame, and can adsorb one side surface of the steel plate on the conveying mechanism, and turn it vertically upward by 90° in a direction away from the conveying mechanism, so that the steel plate is in a vertical direction, and the other side surface of the steel plate can be inspected; after the inspection is completed, the turning mechanism can turn the steel plate downward by 90° in a direction toward the conveying mechanism, so that the steel plate is in a horizontal direction, and the steel plate can be placed on the conveying mechanism.

[0018] When the plate turning machine described in the present invention is actually used, the steel plate can be placed on the conveying mechanism, and the inspector will inspect the quality of the upper surface of the steel plate. After the inspection, the conveying mechanism conveys the steel plate to the bottom of the flipping mechanism, and the flipping mechanism adsorbs and fixes the upper surface of the steel plate, and then flips it vertically upward 90° in the direction away from the conveying mechanism through the flipping structure, so that the steel plate is turned from the horizontal direction to the vertical direction, so that the inspector can perform quality inspection on the lower surface of the steel plate; after the inspection is completed, the flipping mechanism flips the steel plate downward 90° in the direction toward the conveying mechanism, so that the steel plate returns to the horizontal direction, and then the steel plate is placed on the conveying mechanism and conveyed to other workstations for subsequent processing.

[0019] In some embodiments of the present invention, support plates I 3 and II 4 are provided at both ends of the width of the frame 1 near the flipping mechanism. Both support plates I and II are arranged vertically, and the bottoms of support plates I 3 and II 4 are fixedly connected to the frame 1. In a specific implementation, a lifting device may be provided between support plates I 3, II 4, and the frame 1. The lifting device is provided in a one-to-one correspondence with support plates I and II. The lifting device may be a hydraulic press, the bottom of which is fixedly connected to the frame. The lower ends of support plates I and II are respectively fixedly connected to the piston rod of a hydraulic press. Under the action of the hydraulic press, support plates I and II can move up and down in the vertical direction. This provides more ample flipping space when larger steel plates need to be inspected. The flipping mechanism includes a first drive motor 5, a driving gear 18, a driven gear 19, and a support frame 6. The first drive motor is located on one side of the frame and is fixedly connected to the side of support plate I facing support plate II. The driving end of the first drive motor is arranged horizontally and toward the transmission mechanism, and the length direction of the driving end is perpendicular to the length direction of the frame. A driving gear is sleeved on the driving end of the first drive motor, and the axis of the driving gear coincides with the axis of the driving end of the first drive motor. The driven gear is arranged on support plate I 3 and is located on the side of support plate I 3 facing support plate II and is rotationally connected to support plate I 3. The driven gear is located on the side of the driving gear along the horizontal direction and is meshed with the driving gear. Here, the axis of the driven gear and the axis of the driving gear are located in the same plane and are parallel to the axis of the driving gear. Connecting rods I 7 and II 8 are also provided at both ends of the support frame 6 along its length. One end of connecting rod I is fixedly connected to the driven gear so that the connecting rod can rotate with the driven gear, and the other end of connecting rod I is fixedly connected to the support frame. One end of the connecting rod II is fixedly connected to the support frame, and the other end thereof is rotationally connected to the side of the support plate II facing the support plate I. When the driven gear rotates around the axis of the driven gear under the drive of the driving gear, the driven gear will also drive the connecting rod I to rotate around the axis of the driven gear. Since the connecting rod I is fixedly connected to the support frame 6, and the connecting rod II is rotationally connected to the support plate II, when the connecting rod I rotates with the driven gear, it will also drive the connecting rod II to rotate through the support frame 6. An adsorption plate 9 is provided on the support frame 6, and the upper side of the adsorption plate 9 is fixedly connected to the support frame 6; a plurality of suction cups are provided on the lower side of the adsorption plate 9 for adsorbing the steel plate on the conveying mechanism. The first drive motor is a servo motor, and the first drive motor can drive the driving gear 18 to rotate at a certain angle, which can prevent the motor from rotating at an excessively large angle and causing damage to the motor and equipment.When the driving end of the first drive motor rotates clockwise, it can drive the driving gear 18 to rotate a certain angle, and through the driven gear 19, the adsorption plate on the support frame flips vertically upward 90° in the direction away from the transmission mechanism. At this time, the adsorption plate on the support frame is in a vertical plane; when the driving end of the first drive motor rotates counterclockwise, it can drive the driving gear to rotate a certain angle, and through the driven gear, the adsorption plate on the support frame flips downward 90° in the direction toward the transmission mechanism. At this time, the adsorption plate on the support frame is in a horizontal plane. The whole process is safe and fast, and the rapid flipping of steel plates can be achieved without the use of large equipment.

[0020] In some embodiments of the present invention, a plurality of slides 10 and a plurality of vacuum suction cups 11 are provided on the adsorption plate. The positions of the slides can be set and adjusted according to the steel plates of different sizes, and the length directions of the plurality of slides can be perpendicular to each other or parallel to each other, so that the vacuum suction cups sliding in the slides can be adjusted to the core position of the steel plate, so that the vacuum suction cups can not only adsorb steel plates of different sizes, but also achieve better adsorption effects on steel plates of different sizes. A vacuum pump is provided on the support frame, which is fixedly connected to the support frame and is connected to the vacuum suction cup through an exhaust pipe; a slider is provided at the upper end of the vacuum suction cup, which is slidably connected to the slide, and the vacuum suction cup slides in the slide along its length direction through the slider, thereby being able to adjust the position of the vacuum suction cup on the adsorption plate, and the vacuum suction cup is fixed at this position by a locking member. The vacuum suction cup can quickly absorb and fix the steel plate without causing damage to the surface of the steel plate. At the same time, the position of the vacuum suction cup can be adjusted to be suitable for the inspection of steel plates of different sizes, so that the adsorption plate can fix the core position of steel plates of different sizes, and the flip machine can achieve 90° flipping of steel plates of different sizes.

[0021] In some embodiments of the present invention, the transmission mechanism includes a transmission rod 12, multiple transmission rods and a second drive motor 13; wherein the second drive motor is located below the first drive motor and is fixedly connected to the frame; the transmission rod 12 is arranged on one side of the frame along its length direction and is located below the flipping mechanism. The transmission rod is arranged along the width direction of the frame, and its two ends respectively pass through the opposite sides of the frame. The end close to the first drive motor is connected to the first transmission chain 15 through the sprocket I 14, and the first transmission chain is connected to the second drive motor through the sprocket II 16. The second drive motor can drive the first transmission chain 15 to rotate through the sprocket II 16, and then the first transmission chain 15 passes through the sprocket I 14 drives the transmission rod 12 to rotate. The transmission rods are arranged along the width of the frame and spaced apart along its length. Both ends of the transmission rods are rotatably connected to the frame. A second transmission chain is mounted on the transmission rods and the transmission rods. As the transmission rod rotates, the transmission rods are driven by the second transmission chain to rotate synchronously. A conveyor belt 17 is also mounted on the outside of the transmission rods. The conveyor belt 17 is fixedly connected to the outside of the second transmission chain, so that when the second transmission chain rotates synchronously with the transmission rods, it also rotates with the conveyor belt. The steel plates are placed on the conveyor belt and transported to the bottom of the turning mechanism. The conveyor belt is made of a flexible material to prevent damage to the steel plates during transport. Once placed on the conveyor belt, the second drive motor transports the steel plates to the bottom of the turning mechanism, allowing inspectors to directly inspect the surface quality of the upper side of the steel plates on the conveyor belt. The second drive motor then continues to transport the steel plates to the bottom of the turning mechanism, where they are flipped 90° before inspection. After the inspection is completed, the turning mechanism turns the steel plate over again and places it on the conveyor belt. The second drive motor can directly convey the inspected steel plate to the next process for easy processing in the next process.

[0022] In some embodiments of the present invention, two third drive motors are further provided between the support frame 6 and the adsorption plate 9, and the motor shaft of the third drive motor is fixedly connected to the adsorption plate, and the fourth drive motor can drive the adsorption plate to move in the vertical or horizontal direction. When the steel plate is conveyed to the bottom of the adsorption plate by the conveying mechanism, the fourth drive motor drives the adsorption plate to move downward in the vertical direction to above the upper surface of the steel plate, and then the operator adsorbs and fixes the steel plate through the vacuum suction cup on the adsorption plate. If the steel plate is large in size, the adsorption plate can be raised to a certain height in the vertical direction by the fourth drive motor to provide sufficient space for flipping; then it can be flipped 90 degrees to make the steel plate vertical; at this time, the inspector can drive the adsorption plate to move in the horizontal direction by the fourth drive motor, thereby further adjusting the position of the steel plate on the adsorption plate to facilitate inspection by the inspector.

[0023] The present invention is not limited to the above-mentioned embodiments. Any structure that is the same as or similar to the above-mentioned embodiments of the present invention is within the protection scope of the present invention.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution of the present invention should be included in the scope of the claims of the present invention.
