Description

Technical Field

[0001] This application relates to the technical field of workpiece sorting, and in particular to an automatic workpiece sorting device. Background Technology

[0002] In manufacturing processes, disc-shaped workpieces are widely used, such as bearing end caps and flanges. After processing, these workpieces often need to be sorted according to size for subsequent assembly, storage, and transportation. Currently, some companies still use manual sorting for disc-shaped workpieces. This method is not only inefficient and costly, but also prone to worker fatigue due to prolonged work, leading to sorting errors and making it difficult to guarantee accuracy and consistency. Some companies use automated sorting equipment, but existing automated sorting equipment mostly relies on expensive machine vision or artificial intelligence, thus increasing production costs.

[0003] A search revealed Chinese Patent Publication No. CN222743504U, which discloses a slanted wheel sorting machine. The machine includes a mounting plate, an active roller transmission mechanism, a synchronous drive mechanism, and an angle adjustment mechanism. The mounting plate is connected to the machine frame. Four active roller transmission mechanisms are positioned above the mounting plate at the four corners. Each active roller transmission mechanism transmits workpieces and includes active roller groups. Each active roller group includes two parallel long rollers and two short rollers. The synchronous drive mechanism drives the active roller groups of each active roller transmission mechanism to operate synchronously. The angle adjustment mechanism synchronously adjusts the angle of each active roller group.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: existing technologies rely on machine vision or artificial intelligence for workpiece sorting, leading to increased production costs for enterprises. This application aims to address the problems of low efficiency and high cost in manual sorting of disc-shaped workpieces in existing technologies, as well as the reliance on expensive vision systems in existing automated equipment. By setting up a rotating disk with a material-picking plate and upper and lower conveyor rails with gradually widening spacing, workpieces are automatically sorted by diameter, reducing costs and improving efficiency and accuracy. Utility Model Content

[0005] To reduce the sorting costs for enterprises, this application provides an automatic workpiece sorting device.

[0006] This application provides an automatic workpiece sorting device, employing the following technical solution: It includes a base, one side of which is an inclined surface; a rotating groove is formed on the inclined surface; a rotating disk is rotatably connected within the rotating groove; a feeding trough is formed on the rotating disk; the rotating disk is driven by a rotating rod, and multiple material-pulling plates are slidably connected to the outer wall of the rotating rod in the axial direction; the material-pulling plates can be close to or away from the rotating disk; an upper conveyor rail, a lower conveyor rail, and a collection cover are fixedly arranged on the inclined surface; a discharge trough is formed on the rotating groove, with one end of the upper and lower conveyor rails located within the discharge trough; both the upper and lower conveyor rails are perpendicular to the inclined surface, and a support plate is provided on the side of the upper and lower conveyor rails that is in contact with the inclined surface; the distance between the support plates of the upper and lower conveyor rails gradually increases. Through the cooperation of the feeding trough with the upper and lower conveyor rails, workpieces of different specifications can be sorted.

[0007] Optionally, the outer wall of the rotating rod is provided with multiple axial grooves, and each feeding plate is provided with a sliding block that matches the axial groove.

[0008] Optionally, a tension spring is provided on the groove wall of the axial groove away from the rotating disk.

[0009] Optionally, a drive ring is fixedly disposed on the inclined surface; the drive ring is coaxial with the rotating disk, and the end face of the drive ring is parallel to the inclined surface.

[0010] Optionally, the sliding block is provided with a connecting rod, and the connecting rod is provided with a transmission ball, which abuts against the lower end face of the drive ring.

[0011] Optionally, the drive ring is provided with a protrusion.

[0012] Optionally, a drive motor is fixedly mounted on the base, and the output shaft of the drive motor is coaxially and fixedly connected to the rotating rod.

[0013] Optionally, multiple collection boxes are provided below the lower conveyor rail to collect workpieces of different specifications.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. This utility model, by setting a material-pushing plate that can be close to or away from the rotating disk, combined with a drive ring, protrusions, and tension springs, allows the material-pushing plate to be close to the rotating disk when it is located below the rotating disk, thus pushing the workpieces in the collection hood into the feeding trough; when it is located above the rotating disk, it will be away from the rotating disk, allowing excess workpieces in the upper part of the feeding trough to quickly fall into the collection hood through the space between the material-pushing plate and the rotating disk, avoiding accumulation and blockage, thereby improving feeding efficiency.

[0016] 2. This utility model utilizes the characteristic that the distance between the bearing plates of the upper and lower conveyor rails gradually increases. As workpieces of different diameters slide down the inclined plane, they will fall into multiple collection boxes below the lower conveyor rail at different positions due to the relationship between their diameter and the distance between the two bearing plates, thus completing the size classification.

[0023] The following is in conjunction with the appendix Figures 1-5 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] This application discloses an automatic workpiece sorting device. For example... Figure 1As shown, the device includes a base 1, one side of which is an inclined surface 2; a rotating groove 3 is provided on the inclined surface 2; a rotating disk 4 is rotatably connected inside the rotating groove 3; a feeding groove 5 is provided on the rotating disk 4; the rotating disk 4 is driven by a rotating rod 6, and multiple material-pulling plates 7 are slidably connected to the outer wall of the rotating rod 6 in the axial direction; the material-pulling plates 7 can be close to or away from the rotating disk 4; an upper conveying rail 8, a lower conveying rail 9, and a collection cover 10 are fixedly provided on the inclined surface 2; a discharge groove 11 is provided on the rotating groove 3, and one end of the upper conveying rail 8 and the lower conveying rail 9 is located in the discharge groove 11; both the upper conveying rail 8 and the lower conveying rail 9 are perpendicular to the inclined surface 2, and a bearing plate 12 is provided on the side of the upper conveying rail 8 and the lower conveying rail 9 that is in contact with the inclined surface 2; the distance between the bearing plate 12 of the upper conveying rail 8 and the bearing plate 12 of the lower conveying rail 9 gradually increases.

[0025] In this embodiment, a disc-shaped workpiece is placed into the collection hood 10. The bottom surface of the lower feeding plate 7 is in close contact with the upper end surface of the rotating disk 4. The workpiece is continuously fed by the lower feeding plate 7 into the loading groove 5 on the rotating disk 4. The rotating disk 4 transports the workpiece in the loading groove 5 to the bearing plate 12 of the lower conveying rail 9. Under the limitation of the bearing plate 12 of the upper conveying rail 8 and the bearing plate 12 of the lower conveying rail 9, the workpiece will not fall and will slide downward. As the distance between the bearing plate 12 of the upper conveying rail 8 and the bearing plate 12 of the lower conveying rail 9 gradually increases, when the diameter of the workpiece is smaller than the distance between the bearing plate 12 of the upper conveying rail 8 and the bearing plate 12 of the lower conveying rail 9, the workpiece falls.

[0026] In this embodiment, the material feeding plate 7 can be close to or away from the rotating disk 4. When the material feeding plate 7 is located at the lower part of the rotating disk 4, the bottom surface of the material feeding plate 7 is close to the upper surface of the rotating disk 4, which facilitates the material feeding plate 7 to transport the material into the feeding trough 5.

[0027] When the feeding plate 7 is located above the rotating disk 4, the bottom surface of the feeding plate 7 is far away from the upper surface of the rotating disk 4. When the material located above the feeding trough 5 falls, it can quickly fall into the collection hood 10 through the space between the feeding plate 7 and the rotating disk 4, thereby improving the feeding efficiency.

[0028] The surface of the feeding trough 5 can be coated with a paint to increase friction, or a liner to increase friction can be installed.

[0029] Please see Figure 3 and Figure 4The outer wall of the rotating rod 6 has multiple axial grooves 13, and each feeding plate 7 is provided with a sliding block 14 that matches the axial groove 13; a tension spring 15 is provided on the groove wall of the axial groove 13 away from the rotating disk 4; a drive ring 16 is fixedly provided on the inclined surface 2; the drive ring 16 is coaxial with the rotating disk 4, and the end face of the drive ring 16 is parallel to the inclined surface 2; a connecting rod is provided on the sliding block 14, and a transmission ball 17 is provided on the connecting rod, which abuts against the lower end face of the drive ring 16; a protrusion 18 is provided on the drive ring 16;

[0030] In this embodiment, by setting the tension spring 15, the sliding block 14 can always drive the material feeding plate 7 to move upward, and always make the transmission ball 17 abut against the lower end face of the drive ring 16. When the material feeding plate 7 drives the transmission ball 17 to rotate to the upper part, the transmission ball 17 does not abut against the protrusion 18. Under the action of the tension spring 15, the sliding block 14 drives the material feeding plate 7 to move upward, so that the material feeding plate 7 moves away from the rotating disk 4. As a result, when the material located at the upper part of the feeding trough 5 falls, it can quickly fall into the collection cover 10 through the space between the material feeding plate 7 and the rotating disk 4, thereby improving the feeding efficiency.

[0031] When the feeding plate 7 drives the transmission ball 17 to rotate to the lower part, the transmission ball 17 abuts against the protrusion 18. Under the action of the protrusion 18, the sliding block 14 drives the feeding plate 7 to move downward, so that the lower end surface of the feeding plate 7 abuts against the upper end surface of the rotating disk 4, thereby facilitating the feeding of the workpiece in the collection cover 10 to the upper material trough 5.

[0032] Please see Figure 2 A drive motor 19 is fixedly installed on the base 1, and the output shaft of the drive motor 19 is coaxially and fixedly connected to the rotating rod 6.

[0033] In this embodiment, the rotating rod 6 and the rotating disk 4 are driven to rotate by the drive motor 19.

[0034] Please see Figure 1 Multiple collection boxes 20 are installed below the lower conveyor rail 9;

[0035] In this embodiment, as the distance between the support plate 12 of the upper conveyor rail 8 and the support plate 12 of the lower conveyor rail 9 gradually increases, workpieces of different diameters will fall into different collection boxes 20 at different positions.

[0036] The implementation principle of an automatic workpiece sorting device according to an embodiment of this application is as follows:

[0037] The disc-shaped workpiece is placed into the collection hood 10, and the workpieces in the collection hood 10 accumulate below the rotating disk 4; when the feeding plate 7 rotates with the rotating rod 6 to the lower part of the rotating disk 4, the transmission ball 17 abuts against the protrusion 18 of the drive ring 16; under the action of the protrusion 18, the sliding block 14 drives the feeding plate 7 to move downward, so that the bottom surface of the feeding plate 7 is close to the upper end surface of the rotating disk 4, thereby feeding the workpieces in the collection hood 10 into the feeding groove 5 of the rotating disk 4;

[0038] The drive motor 19 drives the rotating rod 6 and the rotating disk 4 to rotate, and the workpiece in the loading groove 5 moves upward with the rotating disk 4; when the feeding plate 7 rotates to the upper part of the rotating disk 4, the transmission ball 17 disengages from the protrusion 18, and under the action of the tension spring 15, the sliding block 14 drives the feeding plate 7 to move upward, so that its bottom surface moves away from the rotating disk 4.

[0039] At this time, excess workpieces located at the top of the feeding trough 5 (those that have not entered the feeding trough 5 and those that have fallen from the feeding trough 5) can fall back into the collection cover 10 through the gap between the material feeding plate 7 and the rotating disk 4, avoiding accumulation and blockage, and improving feeding efficiency.

[0040] When the rotating disk 4 rotates to the discharge trough 11 position, the workpiece in the loading trough 5 is released and falls onto the bearing plate 12 of the lower conveyor rail 9. At the same time, it is limited by the bearing plate 12 of the upper conveyor rail 8 to prevent the workpiece from falling off prematurely.

[0041] The upper conveyor rail 8 and the lower conveyor rail 9 have a gradually widening gap between their bearing plates 12 (i.e., the distance between them gradually increases along the sliding direction of the workpiece). When the workpiece slides down the inclined plane 2, if its diameter is smaller than the current distance between the two bearing plates 12, it will fall due to loss of support; if its diameter is larger, it will continue to slide down the rail until it finds a position that matches the distance and falls.

[0042] Multiple collection boxes 20 are set below the lower conveyor rail 9. Workpieces of different diameters fall into the corresponding collection boxes 20 in sequence during the downward movement, thus completing the size classification.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
