Description

Technical Field

[0001] This utility model relates to the field of playing card sorting technology, and more specifically, to an automatic playing card sorting device. Background Technology

[0002] In the production and processing of playing cards, after packaging, the playing cards need to be sorted to select finished products that meet the appearance requirements and are free from deformation or damage, in order to ensure the quality of the final product. Workers need to visually inspect each box containing the playing cards to determine if there are any problems such as dents, deformation, or abnormal coloring, and then manually separate the qualified products from the defective ones.

[0003] During the transport of playing card boxes, the boxes are prone to positional or angular deviations due to their shape, inertia, or slight vibrations of the conveyor belt. This uncertainty in posture directly leads to deviations in the relative position and angle between the playing card box and the industrial camera when the box arrives at the subsequent vision inspection station. Furthermore, workpieces are prone to congestion, overlap, and even parallel movement on the conveyor line. This disordered state makes it impossible for the inspection system to clearly define each independent inspection target, and the vision system struggles to effectively image and analyze overlapping areas. This results in the inability to achieve reliable, sequential inspection cycles, causing not only interruptions in the inspection process but also potential malfunctions due to the system's inability to identify individual cards, severely impacting the continuity and stability of the entire sorting system. Therefore, we propose an automatic playing card sorting device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an automatic card sorting device to solve the technical problem that card boxes are prone to positional shifts and accumulation during transportation, which affects visual inspection.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic playing card sorting device, including a frame, a fixed frame fixedly installed on the top of the frame, a conveying unit provided on the top of the fixed frame, a centering mechanism and a separating mechanism arranged sequentially inside the fixed frame along the conveying direction, the centering mechanism including a pair of centering plates that can move towards or away from each other, the inlet end of the centering plate being provided with a flared guide plate for guiding the playing card box between the two centering plates, the separating mechanism including a rotary separating plate located at the outlet end of the centering plate, the surface of the separating plate being symmetrically provided with placement grooves, the inner wall of the placement groove being fixedly installed with an elastic sheet, the elastic sheet being arc-shaped and the outer arc surface facing the inlet position.

[0006] Preferably, the centering mechanism further includes a slide rail, on the top of which a sliding frame is symmetrically slidably mounted. The tops of both sliding frames are fixedly mounted to the centering plate via support rods. The top of the fixed frame is rotatably mounted to the center position of the first connecting rod. The two ends of the first connecting rod are respectively rotatably mounted to a second connecting rod and a third connecting rod, and the second connecting rod and the third connecting rod are respectively rotatably mounted to the two sliding frames. The top of the fixed frame is fixedly mounted to a first electric push rod, and the output end of the first electric push rod is fixedly mounted to one of the sliding frames.

[0007] Preferably, the separating mechanism further includes a gear, which is rotatably mounted on the top of the fixed frame. A rotating rod is fixedly mounted on the top of the gear, and the separating disc is fixedly mounted on the top of the rotating rod. A rack that meshes with the gear is fixedly mounted on the outside of the sliding frame, and a reduced guide opening is provided on the inlet side of the placement slot.

[0008] Preferably, the conveying unit is a roller conveying device, and the support rod passes between the two rollers and is fixedly installed with the centering plate, and the rotating rod passes between the two rollers and is fixedly installed with the separator plate.

[0009] Preferably, a groove is provided at the top of the fixing frame at a position symmetrical to the rack, and the rack is slidably installed inside the groove.

[0010] Preferably, it also includes a detection unit, which includes a detection box fixedly installed on the top of the mounting frame. An operation panel is provided on the outside of the detection box, an industrial camera is provided on the inner side of the top of the detection box, and supplementary lights are provided around the industrial camera.

[0011] Preferably, it also includes a feeding unit, which includes a second electric push rod, and a push plate is fixedly installed at the output end of the second electric push rod. The second electric push rod, the operation panel, and the industrial camera are all electrically connected.

[0012] Preferably, the fixed frame is fixedly installed at the tail of the conveying unit with a finished product hopper, and the fixed frame is fixedly installed at the corresponding position of the push plate with a secondary material hopper.

[0013] Preferably, the centering mechanism, the separating mechanism, the detection unit, and the pushing unit are sequentially distributed on the top of the fixed frame along the conveying path.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a flared guide plate to first guide the playing card box between two pairs of center plates, completing the centering and positioning of the playing card box. The separator plate is located at the outlet end of the center plate, allowing the centered playing card box to directly enter the placement slot of the separator plate. Simultaneously, the sliding frame moves, driving the rack and pinion gears to rotate the separator plate synchronously. This coordinated relationship of first using the center plate for positioning and then using the separator plate for orderly transport avoids deviation of the playing card box during transport to the detection unit after centering, ensuring the playing card box enters the next stage with a stable posture. This solves the problem of positional deviation and accumulation of playing card boxes during transport, which affects visual inspection.

[0015] 2. This utility model also utilizes symmetrically designed placement slots on the dividing plate, along with a reduced-size guide port at its entrance, to perform secondary fine-tuning and guiding of the newly aligned playing card boxes. The arc-shaped elastic sheet fixed to the inner wall of the placement slot can flexibly clamp the playing card boxes entering the slot using its own elastic deformation. When the playing card boxes enter, the elastic sheet is compressed and deformed, tightly adhering to the outer wall of the playing card boxes through elastic force. During the rotation and transfer process of the dividing plate, this flexible clamping force can counteract the influence of centrifugal force on the playing card boxes, effectively preventing the playing card boxes from being thrown out of the placement slot, significantly improving the stability of the playing card boxes during the transfer process, and ensuring that each playing card box can be safely and stably transported to the detection unit.

[0018] Example: Figures 1 to 8As shown, this utility model relates to an automatic playing card sorting device, including a frame 1, a fixed frame 11 fixedly installed on the top of the frame 1, a conveying unit 4 provided on the top of the fixed frame 11, the conveying unit 4 being a roller conveying device, with a support rod 221 passing through the space between two rollers and fixedly installed with a centering plate 23, and a rotating rod 32 passing through the space between two rollers and fixedly installed with a separating plate 33. Inside the fixed frame 11, a centering mechanism 2 and a separating mechanism 3 are sequentially arranged along the conveying direction. It also includes a detection unit 5, which includes a detection box 51. The inspection box 51 is fixedly installed on the top of the mounting frame 11. An operation panel 52 is provided on the outside of the inspection box 51. An industrial camera 53 is provided on the inner top of the inspection box 51. Supplementary lights 54 are provided around the industrial camera 53. The system also includes a pushing unit 6, which includes a second electric push rod 61. A push plate 62 is fixedly installed at the output end of the second electric push rod 61. The second electric push rod 61, the operation panel 52, and the industrial camera 53 are all electrically connected. The centering mechanism 2, the separating mechanism 3, the inspection unit 5, and the pushing unit 6 are connected along... The conveying path is sequentially distributed on the top of the fixed frame 11. The fixed frame 11 is located at the tail of the conveying unit 4 and a finished product hopper 13 is fixedly installed. A secondary material hopper 12 is fixedly installed at the corresponding position of the fixed frame 11 and the push plate 62. The centering mechanism 2 includes a pair of centering plates 23 that can move towards or away from each other. The inlet end of the centering plate 23 is provided with a flared guide plate 231 for guiding the playing card box between the two centering plates 23. The separating mechanism 3 includes a rotary separating plate 33 located at the outlet end of the centering plate 23. The surface of the separating plate 33 is symmetrical. A placement slot 34 is provided, and an elastic sheet 342 is fixedly installed on the inner wall of the placement slot 34. The elastic sheet 342 is arc-shaped, with the outer arc surface facing the inlet position. This utility model guides the playing card box into the space between two pairs of center plates 23 through a flared guide plate 231, completing the centering and positioning of the playing card box. The separator plate 33 is located at the outlet end of the centering plate 23, and the aligned playing card box can directly enter the placement slot 34 of the separator plate 33. At the same time, when the sliding frame 22 moves, it drives the rack 35 to mesh with the gear 31, driving the separator plate 33 to rotate synchronously. The cooperation of first using the centering plate 23 for positioning and then using the separator plate 33 for orderly receiving and transfer avoids the deviation of the playing card box when it is transported to the detection unit 5 after centering, ensuring that the playing card box enters the next stage in a stable posture, and solving the problem that the playing card box is prone to positional deviation and accumulation during transportation, which affects visual inspection.

[0019] It should be further noted that in the detection unit 5 of this device, the industrial camera 53 has a built-in image acquisition and data transmission module, and the operation panel 52 has a built-in processor, image recognition software, and data receiving module. The industrial camera 53 is communicatively connected to the operation panel 52 to acquire image information of the playing card box and transmit it to the operation panel 52. The processor calls the image recognition software to perform data analysis to determine whether the product is qualified. The core control of the operation panel 52 is implemented by a programmable logic controller (PLC), which executes the sorting action through the second electric push rod 61. The circuit connection and programming of the PLC controller are mature technologies that can be implemented by those skilled in the art using conventional knowledge. Given that the core of this application's protection lies in the innovative structure and coordinated operation of mechanical devices such as the centering mechanism 2 and the separating mechanism 3, the specific circuit and program of the control system will not be described in detail in the specification.

[0020] Furthermore, the centering mechanism 2 also includes a slide rail 21. Sliding frames 22 are symmetrically slidably mounted on the top of the slide rail 21. The tops of both sliding frames 22 are fixedly mounted to the centering plate 23 via support rods 221. The top of the fixed frame 11 is rotatably mounted to the center position of the first connecting rod 24. The two ends of the first connecting rod 24 are respectively rotatably mounted with a second connecting rod 241 and a third connecting rod 242, and the second connecting rod 241 and the third connecting rod 242 are rotatably mounted to the two sliding frames 22. A first electric push rod 25 is fixedly mounted on the top of the fixed frame 11. The output end of the first electric push rod 25 is fixedly mounted to one of the sliding frames 22. Through the linkage of the first connecting rod 24, the second connecting rod 241, and the third connecting rod 242, the two centering plates 23 can move towards or away from each other, enabling rapid and accurate centering and positioning of the playing card box. This avoids the playing card box shifting during transport, providing a stable positioning basis for subsequent separation and inspection processes, and reducing sorting errors caused by positioning deviations.

[0021] Furthermore, the separating mechanism 3 also includes a gear 31, which is rotatably mounted on the top of the fixed frame 11. A rotating rod 32 is fixedly mounted on the top of the gear 31, and the separating disk 33 is fixedly mounted on the top of the rotating rod 32. A rack 35 that meshes with the gear 31 is fixedly mounted on the outer side of the sliding frame 22. A sliding groove is provided at a position symmetrical to the rack 35 on the top of the fixed frame 11, and the rack 35 is slidably mounted inside the sliding groove. A reduced guide opening 341 is provided on the inlet side of the placement groove 34. This utility model also uses the symmetrically opened placement groove 34 on the separating disk 33 in conjunction with the reduced guide opening 341 at its inlet to enable the separation of the newly completed partitions. The paired playing card boxes undergo secondary fine-tuning and guidance. The arc-shaped elastic sheet 342 fixed to the inner wall of the placement slot 34 can use its own elastic deformation to form a flexible clamp for the playing card boxes entering the slot. When the playing card box enters, the elastic sheet 342 is squeezed and deformed, and tightly adheres to the outer wall of the playing card box through elastic force. During the rotation and transfer process of the separator plate 33, this flexible clamping force can counteract the influence of centrifugal force on the playing card box, effectively preventing the playing card box from being thrown out of the placement slot 34, significantly improving the stability of the playing card box during the transfer process, and ensuring that each playing card box can be safely and stably transported to the detection unit 5.

[0022] Working principle: This embodiment provides an automatic playing card sorting device. In use, the playing card box containing the playing cards to be sorted is placed on top of the conveying unit 4 and conveyed by the conveying unit 4. When the playing card box is conveyed to the guide plate 231, the guide plate 231 guides the playing card box into the space between the two centering plates 23. At this time, the first electric push rod 25 is activated. The output end of the first electric push rod 25 drives the sliding frame 22 to slide on the top of the slide rail 21. Then, the second connecting rod 241 pulls the first connecting rod 241, thereby causing the two sliding frames 22 to move in opposite directions. This causes the centering plates 23 located inside the two sliding frames 22 to move in the center, thus moving the playing card box in the center.

[0023] When the playing card box moves to the rear of the centering plate 23, it enters the symmetrically arranged placement slots 34 on the dividing plate 33. The playing card box is slightly guided by the guide port 341 at the inlet of the placement slot 34, allowing it to enter the placement slot 34. The elastic sheet 342 limits its movement, preventing it from being thrown out due to centrifugal force. When one playing card box enters the placement slot 34, the next playing card box will be blocked by the one already in the slot. When the centering plate 23 opens again, the sliding... The moving frame 22 drives the rack 35 to move, which in turn drives the gear 31 to rotate. The rotation of the gear 31 drives the partition plate 33 to rotate through the rotating rod 32. At this time, the playing card box located at the tail of the centering plate 23 will be blocked by the unnotched part of the partition plate 33, and the placement slot 34 will rotate. When the partition plate 33 is fully opened, the partition plate 33 containing the playing card box rotates 180° to complete the discharge operation and enter the bottom of the detection unit 5. At this time, the playing card box located at the tail of the centering plate 23 enters another placement slot 34.

[0024] When the playing card box enters the bottom of the industrial camera 53, the industrial camera 53 takes a picture of it and transmits the image to the operation panel 52. After receiving the image, the processor in the operation panel 52 measures the width, height or diagonal distance of the card box to determine whether there are serious indentations that cause deformation, as well as the appearance and color. It also uses the supplementary light 54 to supplement the light and optimize the image quality.

[0025] If it is a defective product, the operation panel 52 transmits the action command to the second electric push rod 61, which controls the second electric push rod 61 to push the push plate 62 and push the defective product to the defective material hopper 12. If it is a good product, the second electric push rod 61 does not move and is directly conveyed to the finished product hopper 13.

[0026] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
