Description

Technical Field

[0001] This invention belongs to the technical field of bearing processing equipment, and in particular, it is an automatic sorting and centering device for bearing plates. Background Technology

[0002] In the field of modern machinery manufacturing, bearings are a key basic component, and their production efficiency and quality control are of paramount importance. With the deep application of automation technology in industrial production, the automation process in the bearing manufacturing industry is also continuously advancing. Currently, automated bearing production mainly focuses on processes after bearing forming or semi-forming, such as chamfering, upsetting, deburring, and laser marking. The introduction of these automated processes has improved the efficiency and precision of bearing production to a certain extent. In the processing of bearing plates, bearing plates of different specifications are placed simultaneously in the sintering furnace. This is because a single specification of bearing plate cannot completely fill the internal space of the sintering furnace; processing multiple specifications of plates simultaneously can effectively improve processing efficiency. Inside the sintering furnace, the bearing plates undergo processes such as powder coating, firing, and cooling, and are then slowly output from the furnace outlet, finally being transported by sorting equipment.

[0003] For example, the Chinese patent for an automatic sheet material sorting machine, application number CN201710063823.2, includes a frame, a conveyor belt mounted on the frame that can drive the sheet material to be conveyed, and a circuit controller. The conveyor belt is electrically connected to the circuit controller. The feature is that: the outer side of the conveyor belt is provided with a detection component corresponding to the position of the sheet material, a transverse feeding component, and a transverse discharge stacking component. The conveyor belt is provided with a lifting and distributing component corresponding to the position of the sheet material. The outlet end of the lifting and distributing component is positioned corresponding to the inlet end of the transverse discharge stacking component. The detection component, the transverse feeding component, the lifting and distributing component, and the transverse discharge storage component are respectively electrically connected to the circuit controller. In practical applications, the automatic board sorting machine of this patent has a significant problem: during the transmission of the boards, the detection component detects the boards. When the automatic board sorting machine is running continuously at high speed, the boards may slip or rotate and tilt on the conveyor belt, causing the detection component to fail to accurately align with the boards, resulting in misclassification, size distortion, and misalignment of sorting signals. This positional error is transmitted with each process. Because the position of the boards is unstable during transmission, the accuracy of board detection cannot be guaranteed, nor can the subsequent classification of the boards be guaranteed. Summary of the Invention

[0004] In view of this, the present invention provides an automatic sorting and centering device for bearing plates that can improve the stability of plate transmission to meet industrial needs.

[0005] An automatic sorting and centering device for bearing plates includes a mesh belt conveyor for transporting plates, a conveying mechanism for transporting plates, a transition conveying device disposed between the conveying mechanism and the mesh belt conveyor, a feeding detection mechanism disposed on top of the transition conveying device, a transport mechanism disposed on top of the conveying mechanism, and a centering guide mechanism disposed on the side of the conveying mechanism away from the feeding detection mechanism. Rollers in the mesh belt conveyor drive the mesh belt to rotate. The conveying mechanism includes multiple driven rotating rollers. The transition conveying device includes multiple driven rotating transition rollers. The arrangement direction of the multiple transition rollers is the same as the arrangement direction of the multiple rollers. The total length of the multiple transition rollers along the arrangement direction of the multiple transition rollers is less than the length of the plate. The working surface of the transition roller is lower than the working surface of the roller in the direction perpendicular to the arrangement direction of the multiple transition rollers, and the difference between the height of the working surface of the transition roller and the working surface of the roller is less than the thickness of the plate. The transmission direction of the multiple transition rollers is opposite to the transmission direction of the roller, and the rotational speed of the transition roller is greater than the rotational speed of the roller. When the sheet material enters the transition roller under the drive of the mesh belt, one end of the sheet material abuts against the roller. The conveying speed of the mesh belt and the conveying speed of the roller and the transition roller are adjusted to ensure that one end of the sheet material always abuts against the roller closest to the transition roller, thus aligning one end of a row of sheet materials. The loading detection mechanism is used to detect the length of the workpieces located on the transition roller. Based on the length of the workpieces detected by the loading detection mechanism, the transport mechanism sorts out workpieces of the same length and places them one by one onto the transport mechanism. While transporting workpieces of the same length, the transport mechanism centers the sheet material and outputs it through the centering guide mechanism.

[0006] Furthermore, the feeding detection mechanism includes a mounting plate, a feeding detection sliding assembly mounted on the mounting plate, a connecting plate mounted on the feeding detection sliding assembly, a detection scanner mounted on the feeding detection sliding assembly, and a feeding sensor mounted on the feeding detection sliding assembly.

[0007] Furthermore, the material feeding detection sliding assembly includes a material feeding detection slide rail fixedly connected to the mounting plate, a material feeding detection slider slidably connected to the material feeding detection slide rail, and a material feeding detection drive device disposed on the mounting plate and connected to the material feeding detection slider.

[0008] Furthermore, the transmission mechanism also includes a roller drive device for driving the roller to rotate, and two feeding guide blocks. The multiple rollers are arranged in a row, and the two feeding guide blocks are respectively disposed on both sides of the rollers in the row. The feeding guide blocks are disposed at one end of the worktable near the centering guide mechanism. The gap between the two feeding guide blocks is conical, with the wide end of the cone facing the feeding detection mechanism and one narrow end of the cone facing the centering guide mechanism.

[0009] Furthermore, the transport mechanism includes two first transport guide rail assemblies, a second transport guide rail assembly slidably connected to the first transport guide rail assembly, a first drive assembly disposed between the first and second transport guide rail assemblies, a transport assembly disposed on the second transport guide rail assembly, and a sensing control assembly disposed on the side of the second transport guide rail assembly facing away from the feeding detection mechanism. The extension direction of the first transport guide rail assembly is perpendicular to the extension direction of the second transport guide rail assembly. The transport assembly includes a lifting device disposed on the second transport guide rail assembly and a vacuum suction cup hanger disposed on the lifting device. The centering guide mechanism includes a feeding guide drive device and two clamping plates symmetrically connected to the feeding guide drive device. When the sheet material is transported to the end of the transport mechanism where the centering guide mechanism is disposed, the feeding guide drive device drives the two clamping plates to move towards each other to move the sheet material to the center position of the transport mechanism.

[0010] Furthermore, each of the first transport guide rail assemblies includes a first transport guide rail disposed on the support frame, a first transport slider disposed on the first transport guide rail, and the first drive assembly includes a drive device for driving the second transport guide rail assembly to slide, a rack disposed on one side of the first transport guide rail, and a limiting rod disposed at one end of the rack.

[0011] Furthermore, the first drive assembly includes a drive device for driving the second transport guide assembly to slide, a rack disposed on one side of the first transport guide, and a limiting rod disposed at one end of the rack, the limiting rod being disposed at the end of the rack facing the centering guide mechanism.

[0012] Furthermore, the second transport guide rail assembly includes a mounting plate disposed on the first transport slider, a second transport guide rail disposed on the mounting plate, a central slider slidably connected to the second transport guide rail, and a second transport drive device disposed on the mounting plate and connected to one end of the central slider.

[0013] Furthermore, the second transport guide rail assembly also includes two limiting baffles symmetrically arranged on one side of the mounting plate, and the central slider is disposed between the two limiting baffles.

[0014] Furthermore, the distance between the two limiting baffles is equal to the length of the roller.

[0015] Compared with existing technologies, the automatic sorting and centering equipment for bearing plates provided by this invention detects the position of the workpiece through the feeding and detection mechanism, the transport mechanism places the workpiece onto the transmission mechanism, and then the centering guide mechanism centers the plate. The transition transmission device is positioned between the transmission mechanism and the mesh belt transmission device to compensate for the gap between them, thereby smoothly transferring the plate from the mesh belt transmission device to the transmission mechanism. Since the total length along the arrangement direction of the multiple transition rollers should be less than the length of the plate, the plate enters the transition roller under the drive of the mesh belt, and one end of the plate abuts against the roller, achieving alignment of one end of a row of plates. This ensures stable positioning of the plate on the transition transmission device and accurate detection of the plate's length. Furthermore, the transmission direction of the mesh belt is the same as that of the rollers. The rotational speed of the transition roller is greater than that of the main roller. The transmission speeds of the main roller and the transition roller are adjustable. This allows the conveying speed of the mesh belt, the rollers, and the transition roller to be adjusted so that one end of the sheet material is always pressed against the roller closest to the transition roller, thus ensuring the accuracy of subsequent inspection and classification. Then, with the cooperation of the feeding and inspection mechanism, the material is transferred by the transport mechanism to the centering guide mechanism for centered output. The entire process is accurate and fast, improving the overall efficiency of bearing manufacturing. Attached Figure Description

[0027] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0028] like Figures 1 to 10 The diagram shown is a structural schematic of the automatic bearing plate sorting and centering device provided by the present invention. The automatic bearing plate sorting and centering device includes a mesh belt conveyor 1 for transporting plates 2, a frame portion 10 disposed on one side of the mesh belt conveyor 1, a conveying mechanism 20 disposed on the frame portion 10 for transporting plates, a transition conveying device 30 disposed between the conveying mechanism 20 and the mesh belt conveyor 1, a feeding detection mechanism 40 disposed on top of the transition conveying device 30 and connected to the frame portion 10, a transport mechanism 50 disposed on top of the conveying mechanism 20 and connected to the frame portion 10, and a centering guide mechanism 60 disposed at the end of the conveying mechanism 20 away from the feeding detection mechanism 40. The automatic bearing plate sorting and centering device also includes other functional modules, such as assembly components, electrical connectors, etc., which should be known to those skilled in the art and will not be described in detail here.

[0029] The mesh belt conveyor 1 is a device that transports materials via a continuous mesh belt. It passes through a sintering furnace to sinter the plates 2 placed on the mesh belt 4. The entire process involves feeding, sintering, and unloading. The mesh belt conveyor 1 is driven by a motor to rotate rollers or drums, thereby driving the mesh belt 4. This technology is already in use and will not be described in detail here. Materials are placed on the mesh belt 4, and the movement of the mesh belt 4 facilitates the feeding, sintering, and unloading processes. In this invention, the mesh belt conveyor 1 is connected to the conveying mechanism 20 to transfer the plates 2 from the sintering furnace to the conveying mechanism 20. Then, the conveying mechanism 20, the feeding detection mechanism 40, the transport mechanism 50, and the centering guide mechanism 60 cooperate to sort, transport, center, and output the plates 2 from the sintering furnace.

[0030] It should be noted that during sintering, the lengths and widths of the plates 2 on the mesh belt 4 are not uniform. This facilitates full utilization of the area of ​​the mesh belt 4 structure, thereby making full use of the sintering furnace. Because a single specification of plate 2 may not completely cover the mesh belt 4, in order to fully utilize the sintering furnace, plates 2 of various specifications and lengths are often laid on the mesh belt 4. Therefore, it is necessary to classify these plates 2 of various specifications subsequently.

[0031] The frame portion 10 includes a workbench 11 and two sets of support frames 12 symmetrically arranged on both sides of the workbench 11. The workbench 11 supports the transmission mechanism 20. The support frames 12 support the loading and inspection mechanism 40 and the transport mechanism 50. The height of the support frames 12 is greater than the height of the workbench 11. The support frames 12 and the workbench 11 form two working end faces with different heights. This facilitates the operation and transport of the sheet metal 2 placed on the transmission mechanism 20 by the loading and inspection mechanism 40 and the transport mechanism 50.

[0032] The transmission mechanism 20 includes multiple rollers 21 mounted on the worktable 11 and driven to rotate, a roller drive device 22 for driving the rollers 21 to rotate, and two feeding guide blocks 23 symmetrically arranged on the worktable 11. The multiple rollers 21 are arranged in a row. In this embodiment, a conveyor belt (not shown) connects the roller drive device 22 to the rollers 21, thereby driving the rollers 21 to rotate via the conveyor belt. The rollers 21 and the roller drive device 22 themselves are existing technology and will not be described in detail here.

[0033] Multiple rollers 21 are arranged in a row, and two feeding guide blocks 23 are respectively disposed on both sides of the axial direction of the rollers 21 in the row. The feeding guide blocks 23 are disposed at one end of the worktable 11 near the centering guide mechanism 60. The gap between the two feeding guide blocks 23 is conical, with the wide end of the cone facing the loading detection mechanism 40 and the narrow end of the cone facing the centering guide mechanism 60. Thus, when the plate 2 slides to the centering guide mechanism 60, the feeding guide block 23 guides the plate 2 to be centered on the transmission mechanism 20.

[0034] The transition conveying device 30 includes multiple transition rollers 31 rotatably mounted on the worktable 11 and driven to rotate, and a drive mechanism 32 for driving the transition rollers 31 to rotate. The multiple transition rollers 31 are arranged in a row and positioned at one end of the conveying mechanism 20 near the mesh belt conveying device 1, and the transition rollers 31 rotate under the drive of the drive mechanism 32. The drive mechanism 32 drives the transition rollers 31 to rotate; it can be a drive motor. It is conceivable that, to achieve simultaneous rotation of multiple transition rollers 31, driven pulleys and belts, as well as other structures known in the prior art, are also provided, which will not be described in detail here.

[0035] The transition transmission device 30 is disposed between the transmission mechanism 20 and the mesh belt transmission device 1 to compensate for the gap between them, thereby enabling the smooth transfer of the sheet material 2 from the mesh belt transmission device 1 to the transmission mechanism 20. Since the diameter of the mesh belt roller 3 of the mesh belt transmission device 1 is much larger than the diameter of the roller 21 of the transmission mechanism 20, a gap inevitably exists when the transmission mechanism 20 connects with the mesh belt 4 on the mesh belt roller 3 of the mesh belt transmission device 1. Therefore, when the sheet material 2 on the mesh belt 4 of the mesh belt roller 3 of the mesh belt transmission device 1 comes over, it will inevitably fall into this gap first, making it difficult to be transferred to the transmission mechanism 20. Therefore, the transition transmission device 30 is disposed between the transmission mechanism 20 and the mesh belt transmission device 1 to fill or compensate for this gap, so that the sheet material 2 from the mesh belt transmission device 1 is first transferred to the transition transmission device 30, and then the sheet material 2 on the transition transmission device 30 is transferred to the transmission mechanism 20 for transfer and centered placement. Therefore, the diameter of the transition roller 31 is smaller than the diameters of the mesh belt roller 3 and the roller 21, and the diameter of the transition roller 31 should be such that the plate material cannot fall into the gap between the mesh belt 4 and the transition roller 31. Of course, the diameter of the roller 21 can also be designed to be very small, but this is not conducive to improving the overall transport speed, nor is it conducive to subsequent length detection.

[0036] When setting the transition rollers 31, the arrangement direction of the multiple transition rollers 31 is the same as the arrangement direction of the multiple rollers 21, and the total length formed by the multiple transition rollers 31 along the arrangement direction of the multiple transition rollers 31 should be less than the length of the plate 2. This is because the plate 2 needs to be classified in subsequent inspections, and only its length is inspected during classification, so one end of the plate 2 in a row needs to be aligned. Therefore, when the total length formed by the multiple transition rollers 31 along the arrangement direction of the multiple transition rollers 31 is less than the length of the plate 2, the plate 2 enters the transition roller 31 under the drive of the mesh belt 4, and one end of the plate 2 abuts against the roller 21 under the drive of the mesh belt 4, achieving the purpose of aligning one end of the plate 2 in a row. Precisely because one end of the plate 2 needs to abut against the roller 21, in the arrangement direction perpendicular to the multiple transition rollers 31, the height of the working surface of the transition roller 31 is lower than the height of the working surface of the roller 21, and the height difference between the working surface of the transition roller 31 and the working surface of the roller 21 should be less than the thickness of the plate 2, that is, just enough to abut. If the height difference between the working surfaces of the transition roller 31 and the roller 21 is greater than the thickness of the plate 2, the roller 21 may obscure the end of the plate 2 that abuts against the roller 21, thus affecting the subsequent detection of the length value of the plate 2 and causing inaccurate classification. It should also be noted that the plates 2 on the conveyor belt 4 are usually placed one by one manually or by a robotic arm. When placing the plates 2, their length direction must be the same as the transmission direction of the conveyor belt 4. This is beneficial for subsequent classification and centering, and improves overall work efficiency. Simultaneously, because the total length formed by the multiple transition rollers 31 along the arrangement direction is less than the length of the plate 2, and the height difference between the working surfaces of the transition rollers 31 and the roller 21 is less than the thickness of the plate 2, to prevent the conveyor belt 1 from pushing the plate 2 towards the roller 21 and having the roller 21 carry away the abutting plate 2, the transmission direction of the transition roller 31 should be opposite to the transmission direction of the roller 21, and the rotational speed of the transition roller 31 should be greater than the rotational speed of the roller 21. Because the transmission direction of the mesh belt 4 is the same as that of the roller 21, the mesh belt 4 ensures that one end of the plate 2 is always pressed against the roller 21 closest to the transition roller 31. Due to the requirements of the sintering furnace, the conveying speed of the mesh belt 4 is fixed, while the transmission speeds of the rollers 21 and transition roller 31 are adjustable. Therefore, the conveying speeds of the mesh belt 4, rollers 21, and transition roller 31 should be adjusted to ensure that one end of the plate 2 is always pressed against the roller 21 closest to the transition roller 31, thereby guaranteeing the accuracy of subsequent length detection and, consequently, the accuracy of subsequent sorting.Additionally, it is understood that the total length of the plurality of transition rollers 31 along the arrangement direction should be less than the minimum length of the plate 2, so as to ensure that one end of the plate 2 always abuts against the roller 21 closest to the transition roller 31.

[0037] The feeding detection mechanism 40 includes a mounting plate 41 disposed between the support frames 12, a feeding detection sliding assembly 42 disposed on the mounting plate 41, a connecting plate 43 disposed on the feeding detection sliding assembly 42, a detection scanner 44 disposed on the feeding detection sliding assembly 42, and a feeding sensor 45 disposed on the frame portion 10.

[0038] The two ends of the mounting plate 41 are respectively fixedly connected between the two support frames 12, and one side of the mounting plate 41 is used to install the material feeding detection sliding assembly 42 so that the mounting plate 41 supports the material feeding detection sliding assembly 42.

[0039] The loading detection sliding assembly 42 includes a loading detection slide rail 421 fixedly connected to the mounting plate 41, a loading detection slider 422 slidably connected to the loading detection slide rail 421, and a loading detection drive device 423 disposed on the mounting plate 41 and connected to the loading detection slider 422.

[0040] The feeding detection slider 422 is slidably connected to the feeding detection slide rail 421, and the driving end of the feeding detection driving device 423 is connected to the feeding detection slider 422. The sliding connection structure between the feeding detection slider 422 and the feeding detection slide rail 421, as well as the feeding detection slider 422 and the feeding detection slide rail 421, are all existing technologies and will not be described in detail here.

[0041] The feeding detection drive device 423 is fixedly connected to the mounting plate 41. The drive end of the feeding detection drive device 423 is connected to the feeding detection slider 422, so that the feeding detection drive device 423 drives the feeding detection slider 422 to slide. The feeding detection drive device 423 can be any one of a screw drive device or a cylinder.

[0042] The connecting plate 43 is fixedly connected to the feeding detection slider 422, and the detection scanner 44 and the feeding sensor 45 are mounted on the connecting plate 43. The connection structure between the connecting plate 43, the feeding detection slider 422, and the detection scanner 44 is existing technology and will not be described in detail here.

[0043] The detection scanner 44 is used to measure and detect the dimensions of the board 2 in real time. The detection scanner 44 itself is existing technology. In this embodiment, the detection scanner 44 is a scanning detector capable of detecting the entire surface of the board 2, collecting thousands of points per second to achieve precise measurement of the shape, size, and position of the board 2. In this invention, the detection scanner 44 is used to collect the length of the board 2, and the detection scanner 44 classifies the scanned board 2 according to its length. Since the board 2 is relatively long, to facilitate quick detection and classification of the length of the board 2, one end of the board 2 is aligned, and only the other end of the board 2, i.e., the end facing the mesh belt conveyor 1, needs to be detected. The detection scanner 44 also transmits the information of the classified board 2 to the transport mechanism 50. The transport mechanism 50 sequentially transports boards 2 of the same length. If the detector 44 scans multiple lengths of board 2, the transport mechanism 50 needs to transport a certain length of board 2 before the detector 44 scans and detects it again to transport the next length of board 2, so as to achieve orderly transmission of board 2.

[0044] The loading sensor 45 is used to sense the position of the sheet 2 so as to notify the transport mechanism 50 to pick it up. After the loading sensor 45 determines the position of the sheet 2, it transmits the signal to the transport mechanism 50. The transport mechanism 50 picks up the sheet 2 and moves it to the vicinity of the feeding guide block 23 to facilitate subsequent centering. The loading sensor 45 itself is existing technology. In this embodiment, the loading sensor 45 can be a laser sensor. A laser sensor is a sensor that uses laser technology to perform various measurements such as distance measurement, displacement detection, and object recognition. When the sheet 2 arrives at the transition transmission device 30, it is detected by the detection scanner 44. The loading detection drive device 423 drives the loading detection slide rail 421 to rotate. The detection scanner 44, which is fixed on the loading detection slider 422 by the connecting plate 43, scans and classifies the sheet 2. Then, the transport mechanism 50 is started, that is, the transport mechanism 50 carries the sheet 2 to one end of the centering guide mechanism 60. The scanning area of ​​the detector 44 in the feeding and inspection mechanism 40 is aligned with the transition transmission device 30, thereby scanning and classifying the sheet material 2 on the transition transmission device 30.

[0045] The transport mechanism 50 includes two first transport guide rail assemblies 51 disposed on the support frame 12, a second transport guide rail assembly 52 slidably connected to the first transport guide rail assembly 51, a first drive assembly 53 disposed between the first transport guide rail assembly 51 and the second transport guide rail assembly 52, a transport assembly 54 disposed on the second transport guide rail assembly 52, and a sensing control assembly 55 disposed on the side of the second transport guide rail assembly 52 facing away from the loading detection mechanism 40.

[0046] Two first transport rail assemblies 51 are respectively disposed on two sets of support frames 12, wherein each first transport rail assembly 51 includes a first transport rail 511 disposed on the support frame 12 and a first transport slider 512 disposed on the first transport rail 511.

[0047] Each of the first transport guide rails 511 is fixedly connected to the support frame 12, and the first transport slider 512 is slidably connected to the first transport guide rail 511. The sliding connection structure between the first transport guide rail 511 and the first transport slider 512 is a prior art and will not be described in detail here.

[0048] The second transport guide rail assembly 52 includes a mounting plate 521 disposed on the first transport slider 512, a second transport guide rail 522 disposed on the mounting plate 521, a centering slider 523 slidably connected to the second transport guide rail 522, a second transport drive device 524 disposed on the mounting plate 521 and connected to one end of the centering slider 523, and two limiting baffles 525 symmetrically disposed on one side of the mounting plate 521.

[0049] The two ends of the mounting plate 521 are respectively disposed on the first transport sliders 512 on the two first transport sliders 512, so that the mounting plate 521 can drive the second transport guide rail 522, the center slider 523, and the second transport drive device 524 to slide along the first transport guide rail 511.

[0050] The driving end of the second transport drive device 524 drives the centering slider 523 to slide along the second transport guide rail 522. The second transport drive device 524 can be any one of a cylinder or a lead screw drive mechanism. In this embodiment, the second transport drive device 524 is a lead screw drive mechanism. The connection structure between the second transport drive device 524 and the centering slider 523 is existing technology and will not be described in detail here.

[0051] The limiting baffle 525 is used to restrict the sliding position of the centering slider 523 along the second transport guide rail 522. The centering slider 523 is disposed between the two limiting baffles 525, and the distance between the two limiting baffles 525 is equal to the length of the roller 21. The two limiting baffles 525 are disposed at both ends of the roller 21 to prevent the centering slider 523 from moving outside the transmission mechanism 20. The connection structure between the limiting baffle 525 and the mounting plate 521 is prior art and will not be described in detail here.

[0052] The extension direction of the second transport guide assembly 52 is perpendicular to the transmission direction of the transmission mechanism 20. The extension direction of the first transport guide assembly 51 is perpendicular to the extension direction of the second transport guide assembly 52, so that the first transport guide assembly 51 and the second transport guide assembly 52 can drive the transport assembly 54 to move in different directions, so that the transport assembly 54 is close to the plate 2.

[0053] The first drive assembly 53 includes a drive device 531 for driving the second transport guide assembly 52 to slide, a rack 532 disposed on one side of the first transport guide 511, and a limiting rod 533 disposed at one end of the rack 532. The rack 532 is parallel to the first transport guide 511, so that the transport direction of the rack 532 is consistent with that of the first transport guide 511.

[0054] The driving device 531 is a motor, and a gear is provided at the driving end of the driving device 531. The driving device 531 is mounted on the mounting plate 521, and the gear of the driving device 531 meshes with the rack 532. Therefore, when the driving device 531 drives the gear to rotate, the driving device 531 drives the second transport guide rail assembly 52 to slide along the rack 532 and the first transport guide rail 511. Furthermore, the rack 532 limits the speed of the second transport guide rail assembly 52 as it moves along the first transport guide rail 511, providing a certain degree of protection. The connection structure between the driving device 531 and the rack 532 is existing technology.

[0055] The limiting rod 533 is disposed at one end of the rack 532 facing the centering guide mechanism 60, so as to limit the sliding position of the second transport guide assembly 52 driven by the driving device 531 along the rack 532 and the first transport guide 511.

[0056] The transport assembly 54 includes a mounting bracket 541 disposed on the second transport guide rail assembly 52, a lifting device 542 disposed on the mounting bracket 541, and a vacuum suction cup lifting device 543 disposed on the lifting device 542.

[0057] The mounting bracket 541 is fixedly connected to the centering slider 523, and the lifting device 542 is fixedly connected to the mounting bracket 541. Thus, when the centering slider 523 slides along the second transport guide rail 522, it synchronously drives the lifting device 542 to slide. The lifting device 542 is used to lift the vacuum suction cup lifting device 543, enabling the vacuum suction cup lifting device 543 to pick up and unload materials. In this embodiment, the lifting device 542 is a cylinder. The connection structure between the mounting bracket 541, the centering slider 523, and the lifting device 542 is existing technology and will not be described further here.

[0058] The vacuum suction cup lifting device 543 is a tool that uses negative pressure adsorption to grasp, transport, or fix objects. In this embodiment, the vacuum suction cup lifting device 543 is used to grasp the board 2 and move the board 2. In addition, multiple vacuum suction cup lifting devices 543 are set on the lifting device 542 to ensure the stability of grasping the board 2. The vacuum suction cup lifting device 543 is a prior art and will not be described in detail here. It needs to be further explained that multiple boards are placed manually on the mesh belt 4 one row at a time. After a row is placed, the row of boards is carried away by the mesh belt 4. When the manual removal of the next row of boards takes time, there will be a certain gap between the current board and the previous board when the next board is placed on the mesh belt 4. Therefore, when the first row of boards abuts against the roller 21, it will take a certain amount of time for the second row of boards to move over this gap. Therefore, during this time, the transport component 54 should remove all the boards abutting against the roller 21 to avoid the second row of boards from accumulating on the transition transport device 30.

[0059] The sensing control component 55 is used to sense the sliding position of the first transport guide rail component 51 driving the second transport guide rail component 52. When the first transport guide rail component 51 drives the second transport guide rail component 52 to slide to the unloading position, the first transport guide rail component 51 stops sliding, and the transport component 54 drops the plate 2. The sensing control component 55 is a prior art and will not be described in detail here.

[0060] The centering guide mechanism 60 includes a feeding guide drive device 61 mounted on the support frame 12 and two clamping plates 62 symmetrically connected to the feeding guide drive device 61. When the sheet material 2 is transferred to one end of the transmission mechanism 20 where the centering guide mechanism 60 is located, the feeding guide drive device 61 drives the two clamping plates 62 to move towards each other, thereby moving the sheet material 2 to the center position of the transmission mechanism 20 and ensuring that the sheet material 2 is centered. The connection structure in which the feeding guide drive device 61 drives the two clamping plates 62 to move towards each other is a prior art. In this embodiment, the feeding guide drive device 61 is a screw drive device, and the two clamping plates 62 are respectively mounted on the screw of the screw drive device. The screw has two sections of threads with opposite helical directions, and the two clamping plates 62 are respectively screwed onto the two sections of threads, so that when the screw drive device drives the screw to rotate, the two clamping plates 62 open and close.

[0061] The main power supply of the automatic bearing plate sorting and centering equipment is first turned on manually. At this time, the roller drive device 22 in the transmission mechanism 20 of the transition transmission device is started, causing the roller 21 to start running. The mesh belt transmission device 1 then sequentially transmits the plates 2 to the transition transmission device 30. The drive mechanism 32 in the transition transmission device 30 drives the transition roller 31 to rotate. The conveying speed of the mesh belt 4, the conveying speed of the roller 21 and the transition roller 31 should be such that one end of the plate 2 is always against the roller 21 closest to the transition roller 31, thereby ensuring the accuracy of subsequent length detection and thus the accuracy of subsequent sorting. Furthermore, the feeding detection mechanism 40 corresponds to the transition transmission device 30. When the sheet metal 2 is transported to the designated position of the transition transmission device 30 and detected by the detection scanner 44, the feeding detection sliding component 42 drives the connecting plate 43 to slide along the feeding detection slide rail 421, so that the detection scanner 44 fixed on the connecting plate 43 scans and classifies the size of the sheet metal 2. At the same time, the feeding sensor 45 positions the classified sheet metal 2. Then, the feeding sensor 45 senses the position signal of the sheet metal 2 and transmits it to the transport mechanism 50. The transport mechanism 50 is started. The sliding area of ​​the transport mechanism 50 partially overlaps with the transition transmission device 30, so that the transport mechanism 50 can drive the sheet metal 2 on the transition transmission device 30 to the vicinity of the feeding guide block 23 on the transport mechanism 20. During the process of the transport mechanism 50 driving the sheet metal 2 to slide, the first drive component 53 of the transport mechanism 50 controls the second transport guide rail component 52 to move along the first transport guide rail component 51 to the initial position. The second transport drive device 524 controls... The centering slider 523 and the transport component 54 on the centering slider 523 slide together. The lifting device 542 controls the vacuum suction cup hanger 543 to suck down the plate 2 and then lift it up. Subsequently, the second transport guide rail assembly 52 controls the centering slider 523 to slide along the second transport guide rail 522, dragging the plate 2 and making the plate 2 as centered as possible on the transport mechanism 20. At the same time, the first drive component 53 drives the second transport guide rail assembly 52 to slide along the rack 532 and the first transport guide rail 511, towards the limit. The positioning rod 533 moves in the direction of the limit rod 533. After moving to the limit rod 533, the vacuum suction cup hanger 543 relaxes, allowing the plate 2 to fall. The roller drive device 22 drives the roller 21 to roll and push the plate 2 forward. The feeding guide block 23 guides the plate to be transported to the end of the conveyor belt. Finally, the feeding guide drive device 61 of the centering guide mechanism 60 controls the two clamping plates 62 to move towards each other, and the plate 2 is transported in the center. The subsequent robot arm picks up the plate. The robot arm identifies the classification information of the plate 2 by the detection scanner 44 and transports it to the corresponding processing station in sequence.After the vacuum suction cup lifting device 543 unloads the material, the first drive component 53 controls the first transport guide rail component 51 and the second transport guide rail component 52 to return to their initial positions.

[0062] Furthermore, the transport mechanism 50, based on the length of the workpieces detected by the loading detection mechanism 40, sorts out workpieces of the same length and places them one at a time onto the transmission mechanism 20. Simultaneously, the transmission mechanism 20 centers and outputs the sheet metal via the centering guide mechanism 60 while transporting workpieces of the same length. The phrase "one at a time" in "the transport mechanism 50, based on the length of the workpieces detected by the loading detection mechanism, sorts out workpieces of the same length and places them one at a time onto the transmission mechanism" means that the transport mechanism 50 places the sheet metal 2 onto the transmission mechanism 20 one at a time, not multiple at a time, because the centering guide mechanism 60 needs to perform a centering operation on them; placing multiple sheet metals at once would prevent centering.

[0063] Compared with the prior art, the automatic sorting and centering equipment for bearing plates provided by the present invention detects the position of the workpiece through the feeding detection mechanism 40, the transport mechanism 50 moves the workpiece to the transmission mechanism 20, and then centers the plate 2 through the centering guide mechanism 60. The transition transmission device 30 is set between the transmission mechanism 20 and the mesh belt transmission device 1 to compensate for the gap between the transmission mechanism 20 and the mesh belt transmission device 1, thereby realizing the smooth transmission of the plate 2 on the mesh belt transmission device 1 to the transmission mechanism 20. Since the total length along the arrangement direction of the multiple transition rollers 31 should be less than the length of the plate 2, the plate 2 enters the transition roller 31 under the drive of the mesh belt 4, and one end of the plate 2 abuts against the roller 21 under the drive of the mesh belt 4, so as to align one end of a row of plates 2, realize the stable position of the plate 2 on the transition transmission device 30, and realize the accurate detection of the length value of the plate 2. Furthermore, the transmission direction of the mesh belt 4 is the same as that of the roller 21. The rotational speed of the transition roller 31 is greater than that of the roller 21. The transmission speeds of the roller 21 and the transition roller 31 are adjustable. Therefore, by adjusting the transmission speeds of the mesh belt 4, the roller 21, and the transition roller 31, the values ​​should be such that one end of the plate 2 always rests against the roller 21 closest to the transition roller 31, thus ensuring the accuracy of subsequent inspection and subsequent classification. Then, with the cooperation of the feeding and inspection mechanism 40, it is transferred by the transport mechanism 50 to the centering guide mechanism 60 for centered output. The entire process is accurate and fast, which helps improve the overall efficiency of bearing manufacturing.

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
