Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a centering and correction mechanism. Background Technology

[0002] The sheet material undergoes multiple processing steps during production. Conveying mechanisms are used between adjacent steps to transport the sheet material to the next step. Some steps require high positioning accuracy, necessitating precise conveying of the sheet material. Current technologies typically employ fixed-distance or adjustable-distance correction components on both sides of the conveying mechanism for positioning and correction. Fixed-distance correction components have the following drawbacks: when processing sheet materials of different sizes, repeated manual adjustments between the two correction components are required, consuming significant manpower and resulting in a cumbersome and time-consuming process that severely impacts production efficiency. Adjustable-distance correction components also have the following drawbacks: they require manual intervention to set the distance based on the sheet material. Furthermore, current centering correction mechanisms cannot automatically adjust the distance between the two correction components according to the sheet material width. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] See Figure 1 and Figure 2 As shown, this utility model discloses an embodiment of the centering correction mechanism.

[0026] The aforementioned centering correction mechanism includes a centering correction mechanism comprising:

[0027] The base plate assembly includes the base plate 11;

[0028] Two correction components are mounted on the base plate 11 and located on both sides of the center of the base plate 11 along the X-axis. Each correction component includes a connecting block 21, a transfer plate 22, an elastic reset member 23, and a roller assembly. The transfer plate 22 is movably connected to the connecting block 21 along the X-axis. The elastic reset member 23 applies a reset force to the transfer plate 22 toward the center of the base plate 11. The roller assembly is mounted on the transfer plate 22 and includes a plurality of rollers 24 arranged at intervals along the Y-axis. The rollers 24 can rotate relative to the transfer plate 22 about the Z-axis.

[0029] The drive assembly, mounted on the base plate 11, is used to drive the connecting block 21 of the two correction assemblies to move in opposite directions along the X-axis.

[0030] The first detection component is used to detect whether the transfer plate 22 and the connecting block 21 are in a preset positional relationship.

[0031] The second detection component is used to detect whether the transfer plate 22 and the base plate 11 are in a preset positional relationship.

[0032] In the above text, the base plate assembly refers to the basic platform that supports each functional module, providing stable support for the overall mechanism. The correction assembly refers to the positioning devices symmetrically distributed on both sides of the centerline of the base plate 11. The connecting block 21, transfer plate 22, and elastic reset member 23 ensure that the roller 24 always tends to move towards the center position, thus enabling elastic contact with the plate. The roller 24 rolls in contact with the moving plate and restricts the plate's displacement in the Y-axis direction. The drive assembly refers to the power device that generates synchronous reverse motion, precisely controlling the movement distance of the connecting blocks 21 on both sides. The first detection assembly refers to the sensing device that monitors the relative position of the transfer plate 22 and the connecting block 21 during the clamping process of the two correction assemblies. The second detection assembly refers to the sensing device that confirms the relative position of the transfer plate 22 and the base plate 11 when the two correction assemblies release the plate.

[0033] Specifically, when the two correction components contact the plate, the drive component starts, causing the connecting blocks 21 on both sides to move closer to each other along the X-axis. Before the roller 24 contacts the plate, there is no relative displacement between the transfer plate 22 and the connecting block 21, and the elastic reset member remains in its initial state. When the roller 24 contacts the plate, there is a relative displacement between the transfer plate 22 and the connecting block 21, and the elastic reset member 23 is compressed and stores energy. When the transfer plate 22 and the connecting block 21 are relatively displaced to a preset position, the plate is subjected to a preset clamping force from the roller 24, the drive component stops, and the connecting block 21, transfer plate 22, and roller 24 all stop moving, thus achieving the centering and correction of the plate.

[0034] When the two correction components release the plate, the drive component starts, causing the connecting blocks 21 on both sides to move away from each other along the X-axis. Initially, there is a relative displacement between the transfer plate 22 and the connecting block 21, the roller 24 remains with the plate, and the elastic reset member 23 gradually returns to its shape. When the roller 24 no longer contacts the plate, there is no longer a relative displacement between the transfer plate 22 and the connecting block 21, and they begin to move synchronously. When the transfer plate 22 and the base plate 11 are in a preset position, there is a certain distance between the plate and the roller 24, the drive component stops, and the plate can continue to be transported.

[0035] Through the above technical solution, the spacing is automatically adjusted by driving the two correction components to move in opposite directions. Combined with the elastic reset component 23, the first detection component and the second detection component to monitor the position status in real time, the distance between the two correction components can be adjusted automatically according to the width of the plate.

[0036] In this embodiment, the drive assembly includes two synchronous pulleys 31, a rotary drive device 32, and a synchronous belt 33. The two synchronous pulleys 31 are mounted on the base plate 11 and rotatably connected to the base plate 11 about the Y-axis. The rotary drive device 32 is mounted on the base plate 11 and drives one of the synchronous pulleys 31 to rotate. The synchronous belt 33 is connected to the two synchronous pulleys 31. The two parallel moving parts of the synchronous belt 33 are respectively connected to the connecting blocks 21 of the two correction assemblies.

[0037] In the above text, synchronous pulley 31 refers to the transmission pulley, which drives synchronous belt 33 to form a closed-loop transmission when it rotates around the Y-axis. Rotary drive device 32 refers to the device that provides rotational power, specifically a servo motor or stepper motor, which connects to synchronous pulley 31 via its output shaft to transmit torque. Synchronous belt 33 refers to an annular transmission belt that achieves synchronous transmission with synchronous pulley 31. The two parallel moving parts refer to the two parallel straight line segments formed by synchronous belt 33 during transmission. Specifically, they can be formed by the winding arrangement of synchronous belt 33 around synchronous pulley 31, and are respectively connected to the connecting blocks 21 of the two side correction components to achieve reverse movement.

[0038] Specifically, when the rotary drive device 32 drives one of the synchronous pulleys 31 to rotate, the two parallel segments of the synchronous belt 33 move in opposite directions. Since the two parallel segments of the synchronous belt 33 are fixedly connected to the connecting blocks 21 of the two correction components, the movement of the synchronous belt 33 drives the two connecting blocks 21 to move synchronously in opposite directions along the X-axis.

[0039] The above technical solution, by setting the drive assembly to include a synchronous pulley 31, a rotary drive device 32 and a synchronous belt 33, allows two correction components to move in opposite directions through a single power device, resulting in a simple structure and smooth operation.

[0040] In this embodiment, the first detection component is mounted on the connecting block 21 and the transfer plate 22 of one of the calibration components, and the second detection component is mounted on the transfer plate 22 and the base plate 11 of the other calibration component.

[0041] In the above description, since the two correction components are driven by the same synchronous belt 33, they move synchronously. When the connecting block 21 and transfer plate 22 of one correction component are relatively displaced to a preset position, the connecting block 21 and transfer plate 22 of the other correction component are also relatively displaced to a preset position. When the transfer plate 22 and base plate 11 of one correction component are in a preset position, the transfer plate 22 and base plate 11 of the other correction component are also in a preset position.

[0042] With the above technical solution, one calibration component is set with the first detection component, and the other calibration component is set with the second detection component. The first detection component and the second detection component will not interfere with or affect each other.

[0043] In this embodiment, the above-mentioned correction component further includes a guide shaft 25, which is slidably connected to the connecting block 21 along the X-axis direction. One end of the guide shaft 25 is connected to the transfer plate 22, and the other end of the guide shaft 25 is provided with a limiting ring 251. The elastic reset member 23 is a spring, which is sleeved on the guide shaft 25 between the limiting ring 251 and the connecting block 21.

[0044] In the above text, guide shaft 25 refers to a rigid rod extending along the X-axis direction, which is slidably connected to the shaft hole of connecting block 21. Limiting ring 251 refers to a ring structure fixed to the end of guide shaft 25, which can be an integral or separate structure from guide shaft 25, used to compress the spring. The spring is a helical compression elastic element, sleeved on the outer surface of guide shaft, storing elastic potential energy through compression deformation to provide linear restoring force for transfer plate 22.

[0045] Specifically, when the transfer plate 22 moves along the X-axis under the action of an external force, the guide shaft 25 slides within the shaft hole of the connecting block 21, and the spring is compressed between the limiting ring 251 and the connecting block 21, generating an elastic restoring force proportional to the displacement. After the external force disappears, the spring releases its stored elastic potential energy, pushing the transfer plate 22 to slide back to its initial position along the guide shaft 25.

[0046] Through the above technical solution, by setting the guide shaft 25 and setting the elastic reset member 23 as a spring, the elastic reset member 23 can apply elastic force to the transfer plate 22, and facilitates the installation of the elastic reset member.

[0047] In this embodiment, the first detection component includes a first sensing sheet 41 and a first photoelectric sensor 42. One of the first sensing sheet 41 and the first photoelectric sensor 42 is mounted on the connecting block 21, and the other is mounted on the transfer plate 22.

[0048] The second detection component includes a second sensing element 51 and a second photoelectric sensor 52. One of the second sensing element 51 and the second photoelectric sensor 52 is mounted on the base plate 11, and the other is mounted on the transfer plate 22.

[0049] In the above text, the first sensing sheet 41 refers to a thin metal sheet with a specific shape, which can be made by stamping stainless steel sheet, and is used to trigger the signal change of the first photoelectric sensor 42. The first photoelectric sensor 42 is a photoelectric switch that can detect the position of an object, and determines the relative displacement between the transfer plate 22 and the connecting block 21 by receiving the reflected light signal from the first sensing sheet 41. The second sensing sheet and the second photoelectric sensor use the same principle, but are installed in different positions, and are used to establish a position detection reference between the base plate and the transfer plate.

[0050] Specifically, the first sensing element 41 is located on the side of the first photoelectric sensor 42 near the center of the base plate 11, and the second sensing element 51 is located on the side of the second photoelectric sensor 52 near the center of the base plate 11. When the two calibration components are in the initial state, the first photoelectric sensor 42 can detect the first sensing element 41, and the second photoelectric sensor 52 can detect the second sensing element 51.

[0051] When the two calibration components contact the plate, the drive component is activated, causing the connecting blocks 21 on both sides to move closer to each other along the X-axis. The second photoelectric sensor 52 cannot detect the second sensing element 51. Before the roller 24 contacts the plate, there is no relative displacement between the transfer plate 22 and the connecting block 21, and the elastic reset member remains in its initial state. The first photoelectric sensor 42 can detect the first sensing element 41. When the roller 24 contacts the plate, there is a relative displacement between the transfer plate 22 and the connecting block 21. The elastic reset member 23 is compressed and stores energy. When the first photoelectric sensor 42 cannot detect the first sensing element 41, the transfer plate 22 and the connecting block 21 are relatively displaced to a preset position.

[0052] When the two calibration components release the plate, the drive component starts, causing the connecting blocks 21 on both sides to move away from each other along the X-axis. Initially, there is a relative displacement between the transfer plate 22 and the connecting block 21, the roller 24 remains with the plate, and the elastic reset member 23 gradually returns to its shape. When the roller 24 no longer contacts the plate, there is no longer a relative displacement between the transfer plate 22 and the connecting block 21, and they begin to move synchronously. When the second photoelectric sensor 52 can detect the second sensing sheet 51, the transfer plate 22 and the base plate 11 are in the preset position.

[0053] Through the above technical solution, by setting the first sensing sheet 41, the first photoelectric sensor 42, the second sensing sheet 51 and the second photoelectric sensor 52, the positional relationship between the connecting block 21 and the transfer plate 22 and the positional relationship between the transfer plate 22 and the base plate 11 can be detected in real time.

[0054] In this embodiment, the base plate assembly further includes an adjustment guide rail 12, which extends along the X-axis. One of the second sensing sheet 51 and the second photoelectric sensor 52, which is mounted on the base plate 11, is positionally adjustable and connected to the adjustment guide rail 12.

[0055] In the above text, the adjusting guide rail 12 refers to a linear guide structure extending along the X-axis. Adjustable connection means that the detection component can be fixed at any position on the adjusting guide rail using locking bolts or quick-clamping devices. Specifically, this can be achieved using a sliding pair structure where a slider and guide rail groove cooperate, allowing the position of the second detection component to be flexibly adjusted according to changes in product dimensions.

[0056] Specifically, for a certain size range of board material, the position of the second sensing sheet 51 or the second photoelectric sensor 52 is suitable for a certain size range of board material. When the size of the board material changes significantly, it is necessary to appropriately change the position of the second sensing sheet 51 or the second photoelectric sensor 52.

[0057] The above scheme provides an adjustment guide rail 12, which facilitates the adjustment of the position of the second sensing element 51 or the second photoelectric sensor 52.

[0058] In this embodiment, the base plate assembly further includes a first guide slide rail 13 and two first sliders 14. The first guide slide rail 13 is fixed on the base plate 11, and the two first sliders 14 are respectively fixedly connected to the transfer plates 22 of the two correction assemblies.

[0059] In the above text, the first guide rail 13 refers to a long strip-shaped track structure extending along the X-axis direction, which is fixed on the base plate 11 to form a reference guide surface, used to constrain the movement direction of the transfer plate 22. The two first sliders 14 refer to sliding components that cooperate with the first guide rail 13, and are respectively fixed to the bottom of the transfer plate 22 of the two correction components, allowing the transfer plate 22 to move linearly along the extension direction of the first guide rail 13.

[0060] Through the above technical solution, the calibration component can move precisely relative to the base plate 11 along a preset estimate.

[0061] In this embodiment, the above-mentioned correction component includes a second guide slide rail 26 and a second slider 27. The second guide slide rail 26 is fixed on the connecting block 21, and the second slider 27 is fixed on the transfer plate 22.

[0062] In the above text, the second guide rail 26 refers to a linear guide structure extending along the X-axis direction, whose rigid fixation with the connecting block 21 ensures the integrity of the power transmission path. The second slider 27 refers to a moving component that forms a sliding pair with the second guide rail 26, and its fixed connection with the transfer plate 22 forms a stable bearing interface to prevent deflection torque from being generated during movement.

[0063] Through the above technical solution, the transfer plate 22 can move precisely relative to the connecting block 21 along a preset estimate.

[0064] In this embodiment, the above-mentioned correction component also includes a mounting plate 28, the plurality of rollers 24 are connected to the mounting plate 28, and the mounting plate 28 is fixedly connected to the transfer plate 22.

[0065] In the above description, the mounting plate 28 is a strip extending along the Y-axis, and multiple rollers 24 are sequentially connected to the mounting plate 28 along the Y-axis. The mounting plate 28 is connected to the outer side of the transfer plate 22, and the second slider 27 is connected to the inner side of the transfer plate 22.

[0066] The above technical solution facilitates the overall installation of multiple rollers 24.

[0067] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
