Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal conveying device and sheet metal processing equipment. Background Technology

[0002] Currently, conveyor belts are commonly used for processing and conveying sheet materials. However, for specialized sheet materials like mobile phone coated glass, which are produced in large quantities, traditional conveyor belts can easily cause accumulation during transport due to the numerous subsequent processing steps and long processing times, affecting subsequent processing efficiency. To address this, an S-shaped conveyor belt was designed to buffer the mobile phone coated glass. However, the S-shaped conveyor belt occupies a large amount of space, resulting in a larger overall footprint for the processing equipment. Utility Model Content

[0003] In view of this, the present invention provides a sheet material conveying device and sheet material processing equipment to solve the problem that the S-shaped conveyor belt occupies a large amount of space during the sheet material conveying process.

[0004] In a first aspect, this utility model provides a sheet metal conveying device, comprising:

[0005] At least two spoke-type flipping mechanisms are spaced apart along the conveying direction, and each spoke-type flipping mechanism is provided with at least one buffer position for the plate.

[0006] The sheet material conveying mechanism is connected in sequence with at least two spoke-type overturning mechanisms along the conveying direction, including an upstream loading position and a downstream unloading position.

[0007] In this invention, the sheet material enters the buffer position of the spoke-type flipping mechanism via a sheet material conveying mechanism and rotates with the spoke-type flipping mechanism, thereby forming a three-dimensional space for buffering. This three-dimensional space is centered on the rotation axis of the spoke-type flipping mechanism, and the circular motion of the spokes expands the buffering path of the sheet material from a planar plane to a three-dimensional dimension. Specifically, the sheet material is distributed radially along the spokes during rotation, with adjacent sheet materials staggered, thus increasing the buffer capacity per unit space. Furthermore, the arrangement of at least two spoke-type flipping mechanisms ensures that the sheet material always maintains the same surface facing upwards during loading and unloading, facilitating subsequent identification.

[0008] In contrast, existing S-shaped conveyor belts rely on planar paths for buffering. To achieve the same buffering capacity, the total path length needs to be increased by extending the conveying length or making multiple turns, resulting in the conveying equipment occupying a relatively large area in the horizontal direction and expanding the space occupied by the entire processing equipment.

[0009] Therefore, the buffer space formed by the spoke-type flipping mechanism of this utility model is more compact and occupies less space compared to the existing S-shaped conveyor belt.

[0010] In addition, the buffer position on the spoke-type turning mechanism can temporarily store sheet metal. When there is a brief pause downstream, the upstream sheet metal can be temporarily stored in the buffer position to prevent upstream equipment from stopping production due to untimely material feeding. Sheets that first enter the spoke-type turning mechanism from the sheet metal conveying mechanism can first be sent out from the downstream unloading position, realizing the first-in-first-out buffer function and ensuring production continuity.

[0011] In one alternative embodiment, the distance between the rotating shafts of two adjacent spoke-type overturning mechanisms is greater than or equal to the sum of the lengths of the two plates along the conveying direction.

[0012] In this invention, when the sheet metal is transferred between two adjacent spoke-type flipping mechanisms, the sheet metal is located between two rotating shafts. By setting the distance between the rotating shafts of the two adjacent spoke-type flipping mechanisms to be greater than or equal to the sum of the lengths of the two sheet metals along the conveying direction, the sheet metal will not interfere with the circumferential surface of the rotating shafts when it is located between the two rotating shafts, and the circumferential surfaces of the two rotating shafts will not squeeze the sheet metal. This ensures that there is sufficient space between the two rotating shafts during the transfer process, avoiding possible damage to the sheet metal during flipping and transfer. The sheet metal conveying device can operate stably for a long time.

[0013] In one alternative implementation, the distance between the pivots of two adjacent spoke-type overturning mechanisms is equal to the sum of the lengths of the two plates along the conveying direction.

[0014] In this invention, the specific distance between the rotating shafts of two adjacent spoke-type flipping mechanisms is set to the sum of the lengths of the two plates along the conveying direction. After leaving the previous spoke-type flipping mechanism, the plate can seamlessly enter the working range of the next spoke-type flipping mechanism, reducing idle travel and waiting time during the conveying process and increasing the material processing capacity per unit time. At the same time, the two spoke-type flipping mechanisms are positioned relatively compactly, which can further compress the overall length of the entire plate conveying device and reduce the area occupied.

[0015] In an optional embodiment, a guiding mechanism is further included, the guiding mechanism comprising two guide plates axially spaced along the spoke-type overturning mechanism, the distance between the two guide plates being equal to the length of the plate in the direction perpendicular to the conveying direction.

[0016] In this invention, two guide plates, spaced axially along the spoke-type flipping mechanism with a spacing equal to the width of the sheet material, are always attached to the two ends of the sheet material during the conveying process of the spokes. This prevents problems such as lateral slippage, tilting, or even multi-layer stacking of the sheet material during rotation or handover. It guides and restricts the movement trajectory of the sheet material during flipping and conveying, avoiding the risk of mechanical damage to the edges of the sheet material and the downtime for maintenance caused by material jamming or inaccurate positioning.

[0017] In one optional embodiment, a board identification device is further included, which is located in the conveying direction of the board conveying mechanism and has a board identification position.

[0018] In this utility model, the board identification device can identify and confirm the information of the board at the board identification position, and determine whether the board is a qualified product or a non-qualified product. It can remind the staff to prevent the mixing of boards of different qualities. It can also establish an information monitoring system for each board through the information management system.

[0019] In one optional embodiment, the board material identification device includes:

[0020] A sheet material input mechanism is connected to the sheet material conveying mechanism, and the sheet material identification position is set on the sheet material input mechanism;

[0021] A visual positioning mechanism is positioned above the material identification area;

[0022] The board visual recognition mechanism is connected to a first planar moving module, which is signal-connected to a visual positioning mechanism so that the board visual recognition mechanism is set to correspond with the board recognition position.

[0023] In this invention, the board input mechanism is connected to the board conveying mechanism and is equipped with a dedicated board identification position. This allows for automatic identification and information collection of the board, enabling the connection between physical conveying and information management, and facilitating the establishment of an information monitoring system for each board. A visual positioning mechanism identifies the position of the board and obtains the relative position between the board and the identification position. This, in conjunction with a first planar moving module, drives the board visual identification mechanism to move to the optimal identification point, such as directly above the board. This invention can adaptively compensate for positional deviations of the board during conveying, ensuring the clarity and accuracy of barcode scanning or image acquisition, improving the success rate and stability of board information reading, and enabling full traceability of the board. The integrated identification of the board identification device reduces reliance on manual positioning, lowers operational complexity and labor costs, and avoids scanning failures or information errors caused by large physical positioning errors, making it particularly suitable for high-standard quality management scenarios. Furthermore, the real-time uploading of board identification data provides timely and accurate data support for production statistics, quality analysis, and order tracking, contributing to the digitalization of the production process.

[0024] Secondly, this utility model also provides a sheet metal processing equipment, comprising:

[0025] Such as the sheet metal conveying device mentioned above;

[0026] It also includes packaging equipment.

[0027] In one optional embodiment, the packaging device includes a box conveying mechanism and a packaging mechanism, wherein the packaging mechanism has a packaging position located on the conveying path of the box conveying mechanism.

[0028] In this invention, the packaging device specifically includes a box conveying mechanism and a packaging mechanism. The packaging position is directly set on the conveying path of the box conveying mechanism, allowing packaging to be performed on the conveying path itself. Spatially, box conveying and sheet packaging can be integrated; temporally, box conveying and sheet packaging can be synchronized. Empty box conveying, sheet loading, and full box output can be completed in a continuous process, reducing sheet transfer and potential multiple positioning during transfer, thus improving the efficiency and stability of the packaging process.

[0029] In one optional embodiment, the box conveying mechanism includes:

[0030] The box input mechanism has a box identification position;

[0031] A box-shaped visual recognition mechanism is connected to a second planar moving module so that the box-shaped visual recognition mechanism is set to correspond to the box-shaped recognition position;

[0032] A box lifting mechanism is located at the output end of the box input mechanism, and the packaging position is located on the lifting path of the box lifting mechanism.

[0033] This invention achieves automated box supply, identification, and precise positioning. The box input mechanism supplies empty boxes, while the box vision recognition mechanism, driven by the second planar moving module, aligns with the box identification position and reads the marking information on the box, ensuring that the information of each box is recorded and matched with system information. This enables information binding between the board material and the box, facilitating a traceable production process. The box lifting mechanism receives the identified empty boxes and raises them to a preset packaging height, i.e., the packaging position, preparing the material handling mechanism for picking up and placing the board material. This invention ensures the consistency of information between the board material and the box, eliminates the possibility of misusing the wrong box, and improves the standardization and automation level of the packaging process.

[0034] In one optional implementation, the packaging mechanism includes:

[0035] The material handling mechanism is located between the sheet metal input mechanism and the packing station;

[0036] A box output mechanism is located downstream of the material handling mechanism to enable the output of finished products from the packaging station.

[0037] In this invention, the sheet material input mechanism and the packaging position are located within the working range of the material handling mechanism, allowing the sheet material to be placed into the box at the packaging position. The information of the picked-up sheet material and the box are matched; qualified sheet material is placed into the box containing pre-stored qualified products, and unqualified sheet material is placed into the box containing pre-stored unqualified products, completing the precise conversion of the sheet material from individual to packaged finished product. The box output mechanism can output the packaged finished product. The entire packaging process of this invention requires no manual intervention, reducing quality fluctuations caused by human factors, ensuring the consistency and traceability of packaging quality, and enabling automated integration with downstream logistics or warehousing processes.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] Currently, the buffer structure for sheet materials, such as coated glass for mobile phones, uses an S-shaped, back-and-forth bending design. This structure occupies a large space and requires numerous connecting mechanisms to allow the glass to constantly change direction within the curved S-shaped buffer structure. This results in long circulation distances, numerous structural elements, and issues such as jamming, padding, and uneven transport of coated glass during transport. Furthermore, product barcode scanning is mostly done physically, leading to significant errors and inconsistent scanning success rates. The lack of buffer channels for packaging and unloading means that untimely packaging and unloading can cause upstream equipment shutdowns, impacting production efficiency and thus increasing production and maintenance costs.

[0048] Therefore, this utility model provides a sheet material conveying device and sheet material processing equipment, which can realize the functions of sheet material buffering, scanning, sorting and packaging, while also simplifying the structure of the entire equipment, reducing space, improving transmission smoothness, improving scanning accuracy, increasing packaging and unloading buffer channels and buffer time, thereby improving the overall pass rate and reducing production and maintenance costs.

[0049] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0050] Example 1

[0051] This utility model provides a sheet material conveying device. This embodiment uses coated glass as an example for illustration. Figure 1 and Figure 2 As shown, it includes:

[0052] At least two spoke-type flipping mechanisms 10 are arranged at intervals along the conveying direction. Each spoke-type flipping mechanism 10 is provided with at least one buffer position for the plate. The spoke-type flipping mechanism 10 can buffer a certain number of plates. Different requirements for the front and back sides of the plate output can be achieved by changing the number of spoke-type flipping mechanisms 10. Combined with the identification device, the front and back sides of the plate can be scanned.

[0053] Among them, such as Figure 2 As shown, the spoke-type flipping mechanism 10 may include a rotating shaft located in the middle and support rollers 11 disposed on the circumferential surface of the rotating shaft. There are multiple sets of support rollers 11, with at least two support rollers 11 in each set. The plane of each set of support rollers 11 passes through the axis of the rotating shaft. The position between two adjacent sets of support rollers 11 is a buffer position. When transporting sheet metal, the spoke-type flipping mechanism 10 places the sheet metal in the buffer position. This mechanism offers advantages of high efficiency, stability, and high space utilization for sheet metal buffering and transport. The fact that each set of support rollers 11 contains at least two rollers, and that their planes all pass through the axis of the rotating shaft, ensures the balance and uniformity of the supporting torque. This allows the sheet metal to receive reliable support when placed in the buffer position formed by two adjacent sets of support rollers 11, preventing bending, swaying, or tilting due to insufficient support. During operation, the rotating shaft drives the entire set of support rollers 11 to rotate, causing the sheet metal to circulate in three-dimensional space with the buffer position. This transforms the traditional two-dimensional planar buffer path into a three-dimensional circulating mode, increasing the buffer capacity per unit area and saving overall layout space. Meanwhile, it enables strict first-in-first-out (FIFO) management, ensuring consistency between the turnover sequence of the sheets and the production cycle, and avoiding quality problems or production interruptions caused by material retention. In addition, it reduces the number of guiding and connecting components commonly found in traditional conveying systems, lowers the complexity of the mechanism and maintenance costs, while improving the reliability of sheet transmission and eliminating the risk of failures such as jamming and stacking.

[0054] Alternatively, the spoke-type flipping mechanism 10 may include a rotating shaft located in the middle and multiple support plates disposed on the circumference of the rotating shaft. The plane of each support plate passes through the axis of the rotating shaft, and the position between two adjacent support plates is a buffer position. When transporting the sheet material, the spoke-type flipping mechanism 10 places the sheet material in the buffer position. During operation, the sheet material can be stably placed on the support plates and rotate with the rotating shaft, realizing three-dimensional circulating buffering of materials in three-dimensional space. The support plates can provide surface support for the sheet material, and compared with the line support of the support rollers 11, the support plates can have better stability.

[0055] It should be noted that the bracket has space for the support roller 11 or support plate to rotate, and does not interfere with the rotation of the support roller 11 or support plate.

[0056] In addition, the support roller 11 or support plate can be detachably connected to the rotating shaft, and the size and number of buffer positions can be adjusted according to actual needs to change the maximum buffer capacity on the spoke-type flipping mechanism 10, which can prevent material blockage problems in the upstream and downstream.

[0057] like Figure 2 As shown, the spoke-type flipping mechanism 10 can be mounted on a support frame. One end of the rotating shaft can be rotatably connected to the support frame, and the other end can be fixedly connected to a drive motor 12. The drive motor 12 can be fixed on the support frame and connected to the controller. A fiber optic detection amplifier 13 can be installed at the loading position and connected to the controller. The fiber optic detection amplifier 13 is suitable for detecting whether there is a board in the buffer position. When a board is detected in the buffer position, the controller controls the drive motor 12 to rotate the rotating shaft. When no board is detected, the controller controls the drive motor 12 to stop rotating.

[0058] A sheet metal conveying mechanism 20 is formed by sequentially connecting at least two of the spoke-type flipping mechanisms 10 along the conveying direction. Each sheet metal conveying mechanism 20 includes an upstream loading position and a downstream unloading position. The sheet metal conveying mechanism 20 can be a conveyor belt or a conveying module, and this embodiment of the invention is not limited thereto. The sheet metal conveying mechanism 20 can be mounted on a support and signal-connected to a controller, which can control the sheet metal conveying mechanism 20 and the drive motor 12 to operate synchronously.

[0059] In this invention, the sheet material enters the buffer position of the spoke-type flipping mechanism 10 via the sheet material conveying mechanism 20 and rotates with the spoke-type flipping mechanism 10, thereby forming a three-dimensional space for buffering. This three-dimensional space is centered on the rotation axis of the spoke-type flipping mechanism 10, and the buffering path of the sheet material is extended from a planar plane to a three-dimensional dimension through the circular motion of the spokes. Specifically, the sheet material is distributed radially along the spokes during rotation, with adjacent sheet materials arranged in a staggered manner, thus increasing the buffer capacity that can be accommodated per unit space.

[0060] In contrast, existing S-shaped conveyor belts rely on planar paths for buffering. To achieve the same buffering capacity, the total path length needs to be increased by extending the conveying length or making multiple turns, resulting in the conveying equipment occupying a relatively large area in the horizontal direction and expanding the space occupied by the entire processing equipment.

[0061] Therefore, the buffer space formed by the spoke-type flipping mechanism 10 of this utility model is more compact and occupies less space compared to the existing S-shaped conveyor belt.

[0062] In addition, the buffer position on the spoke-type flipping mechanism 10 can temporarily store the sheet metal. When there is a brief pause downstream, the upstream sheet metal can be temporarily stored in the buffer position to prevent the upstream equipment from stopping production due to untimely material feeding. The sheet metal that first enters the spoke-type flipping mechanism 10 from the feeding position of the sheet metal conveying mechanism 20 can be sent out from the downstream feeding position first, which can realize the first-in-first-out buffer function and ensure production continuity.

[0063] In one alternative embodiment, the distance between the rotating shafts of two adjacent spoke-type flipping mechanisms 10 is greater than or equal to the sum of the lengths of the two plates along the conveying direction.

[0064] In this invention, when the sheet material is transferred between two adjacent spoke-type flipping mechanisms 10, the sheet material is located between two rotating shafts. By setting the distance between the rotating shafts of the two adjacent spoke-type flipping mechanisms 10 to be greater than or equal to the sum of the lengths of the two sheet materials along the conveying direction, the sheet material will not interfere with the circumferential surface of the rotating shaft when it is located between the two rotating shafts, and the circumferential surfaces of the two rotating shafts will not squeeze the sheet material. This ensures that there is sufficient space between the two rotating shafts during the transfer process, avoiding possible damage to the sheet material during flipping and transfer. The sheet material conveying device can operate stably for a long time.

[0065] It should be noted that the distance between the rotating shafts of two adjacent spoke-type flipping mechanisms 10 is greater than the sum of the lengths of the two plates along the conveying direction. The two spoke-type flipping mechanisms 10 are connected by a plate conveying mechanism 20. The plate conveying mechanism 20 can convey the plate on the spoke-type flipping mechanism 10 located upstream to the spoke-type flipping mechanism 10 located downstream, so as to complete the buffering and conveying of the plate.

[0066] In one alternative embodiment, the distance between the rotating shafts of two adjacent spoke-type flipping mechanisms 10 is equal to the sum of the lengths of the two plates along the conveying direction.

[0067] In this invention, the specific distance between the rotating shafts of two adjacent spoke-type flipping mechanisms 10 is set as the sum of the lengths of the two plates along the conveying direction. After leaving the previous spoke-type flipping mechanism 10, the plate can seamlessly enter the working range of the next spoke-type flipping mechanism 10, reducing idle travel and waiting time during the conveying process and increasing the material processing capacity per unit time. At the same time, the two spoke-type flipping mechanisms 10 are positioned relatively compactly, which can further compress the total length of the entire plate conveying device and reduce the area occupied.

[0068] In one alternative implementation, such as Figure 2 As shown, it also includes a guide mechanism 30, which includes two guide plates 31 spaced apart along the axial direction of the spoke-type flipping mechanism 10. The distance between the two guide plates 31 is equal to the length of the plate in the direction perpendicular to the conveying direction.

[0069] In this invention, two guide plates 31, which are axially spaced along the spoke-type flipping mechanism 10 and whose spacing is equal to the width of the plate, are always attached to the two ends of the plate during the conveying process of the spokes. This prevents the plate from lateral slippage, tilting, or even multi-layer stacking during rotation or handover. It guides and restricts the movement trajectory of the plate during flipping and conveying, avoiding the risk of mechanical damage to the edges of the plate and the downtime for maintenance caused by material jamming or inaccurate positioning.

[0070] The guide plate 31 can be an integral baffle extending from the loading position to the unloading position. The top surface of the guide plate 31 can be a plane parallel to the conveying direction. When the material is at its highest position, the length of the guide plate 31 in contact with the material can be no less than three-quarters of the length of the material along the conveying direction. The guide plate 31 can guide the transport of the material in the conveying direction, preventing the material from falling out of the buffer position or tilting during the conveying process.

[0071] The guiding mechanism 30 also includes a cover plate, which is disposed between the two guiding plates 31 and extends from the loading position to the unloading position. The cover plate includes a first arc-shaped plate, a horizontal plate, and a second arc-shaped plate connected in sequence. The first distance between the first and second arc-shaped plates and the rotating shaft of the adjacent spoke-type flipping mechanism 10, and the second distance between the horizontal plate and the plate conveying mechanism 20, are both equal to the length of the plate along the conveying direction. By precisely setting the first distance between the first and second arc-shaped plates and the rotating shaft of the adjacent spoke-type flipping mechanism 10, and the second distance between the horizontal plate and the plate conveying mechanism 20, both are equal to the length of the plate along the conveying direction. The cover plate can form a closed guiding channel in three-dimensional space that closely conforms to the movement trajectory of the plate throughout its entire conveying process. The shapes of the first and second arc-shaped plates can match the motion envelope of the plate when the spoke-type flipping mechanism 10 rotates. This provides continuous and smooth guiding support during the transition phase when the plate enters and leaves the spoke-type flipping mechanism 10, preventing the plate from shifting, tilting, or jumping out of the buffer position due to centrifugal force or inertia, thus ensuring the stability and reliability of the flipping process. The horizontal plate provides top landing point constraint for the plate's straight-line movement on the conveying mechanism. Together with the guide plates 31 on both sides, it avoids the plate from jumping up and down or moving back and forth due to vibration or airflow during high-speed conveying, thus improving the smoothness of the transmission.

[0072] Alternatively, the guiding mechanism 30 may include a plurality of guide rods spaced axially along the spoke-type flipping mechanism 10. The guide rods are respectively positioned on both sides of the spoke-type flipping mechanism 10, and guide rods on the same side can form a guiding surface. The distance between two guiding surfaces is equal to the length of the sheet material perpendicular to the conveying direction. The guiding surface formed by the guide rods provides linear guiding constraint for the conveying process of the sheet material, and their spacing prevents lateral displacement or deviation of the sheet material during conveying, especially during flipping. Compared to a completely enclosed solid plate-shaped guide surface, using guide rods reduces the possibility of large-area contact with the sheet material, thereby reducing frictional resistance and operating noise. This is particularly suitable for coated glass with extremely high requirements for surface integrity, avoiding scratches or edge damage to the film layer that may be caused by hard contact or excessive constraint.

[0073] In one alternative implementation, such as Figure 3As shown, the system also includes a board identification device 40, which is located in the conveying direction of the board conveying mechanism 20 and has a board identification position 411. Specifically, the board identification device 40 can be located downstream of the unloading position of the board conveying mechanism 20, or it can be located between the two spoke-type flipping mechanisms 10. Several sets of board identification devices 40 can also be installed at appropriate positions on the board conveying mechanism 20 according to actual conditions. In this embodiment, the board identification device 40 can be located downstream of the unloading position of the board conveying mechanism 20, but this is not a limitation.

[0074] In this utility model, the board identification device 40 can identify and confirm the information of the board at the board identification position 411, and know whether the board is a qualified product or an unqualified product. It can remind the staff to prevent the mixing of boards of different qualities. It can also establish an information monitoring system for each board through the information management system.

[0075] The board material identification device 40 may include a conveyor belt connected to the board material conveying mechanism 20. Board materials are conveyed to the conveyor belt via the board material conveying mechanism 20. The conveyor belt may be provided with board material identification positions 411, and an identification camera may be installed directly above the board material identification positions 411. The identification camera is suitable for identifying information about the board materials to determine whether the board materials are qualified or unqualified. The board materials are transferred to the conveyor belt via the board material conveying mechanism 20 and are finally conveyed to the preset board material identification positions 411. The fixed board material identification positions 411 provide a stable and repeatable shooting environment for image recognition. The identification camera can collect images and identify information about the board materials on the conveyor belt from top to bottom, thereby accurately determining whether the board materials are qualified or unqualified. This can provide a data source for subsequent product information traceability, classification and packaging, and production data statistics.

[0076] Alternatively, a visual recognition camera can be installed on the board material identification position 411. Simultaneously, the board material identification position 411 integrates non-visual sensors such as RFID readers, laser scanners, or ultrasonic detectors. Multiple sensors based on different principles work collaboratively to simultaneously collect feature information of the board material from different physical dimensions (optical, electromagnetic, acoustic, etc.). A central processing unit performs data fusion and comprehensive judgment to ultimately confirm the board material's identity information and quality status (qualified / unqualified). This improves the accuracy and robustness of board material identification. When one sensor fails or degrades due to environmental interference (such as strong light, oil stains, or obstructions), other sensors can provide redundant and complementary information, ensuring the system can make reliable judgments even under complex conditions. This embodiment expands the application scenarios of the board material conveying device, enabling it to adapt to a wider range of materials (such as metals and non-transparent composite materials) and more complex identification methods (such as barcodes, QR codes, RFID tags, and specific geometric features).

[0077] In one alternative implementation, such as Figure 3 As shown, the board material identification device 40 includes:

[0078] The plate input mechanism 41 is connected to the plate conveying mechanism 20. Specifically, the plate input mechanism 41 can be connected to the unloading position of the plate conveying mechanism 20. According to the recognition requirements, the plate recognition position 411 is set on the plate input mechanism 41. A visual positioning mechanism 42 is set above the plate recognition position 411. A plate visual recognition mechanism 43 is connected to a first planar moving module. The first planar moving module is signal connected to the visual positioning mechanism 42 so that the plate visual recognition mechanism 43 is set to correspond with the plate recognition position 411.

[0079] The board input mechanism 41, visual positioning mechanism 42, and board visual recognition mechanism 43 can be mounted on a support. The board input mechanism 41 can be a belt conveyor with baffles. When the board is on the belt conveyor, it is positioned between the two baffles, thus limiting its movement. The visual positioning mechanism 42 can be mounted above the board recognition position 411 via the support. It can include a camera lens and be connected to a controller. After the camera lens captures an image of the board, the controller can analyze the image to obtain the offset distance and direction of the board relative to the board recognition position 411. The first planar movement module can be an XY planar movement module. The board visual recognition mechanism 43 can integrate a barcode scanner and a recognition lens. The board visual recognition mechanism 43 can be located between the board input mechanism 41 and the visual positioning mechanism 42. The board visual recognition mechanism 43 is mounted on the first planar movement module. The controller can control the first planar movement module to move the board visual recognition mechanism 43 directly above the board, where the board visual recognition mechanism 43 scans and identifies the board. The visual positioning mechanism 42 is fixed directly above the board recognition position 411 via a bracket. Its included camera lens is signal-connected to the controller, enabling it to quickly capture real-time images of the board. The controller then analyzes these images to calculate the offset distance and direction between the board's current actual position and the ideal recognition position, obtaining precise pose feedback. Based on the offset data provided by the visual positioning mechanism 42, the controller further drives the first planar movement module, namely the XY plane movement module, which in turn drives its integrated board visual recognition mechanism 43 to perform precise compensation motion in a two-dimensional plane. Ultimately, this ensures that the optical axis of the recognition lens automatically aligns with the center of the board or the actual position of the code. This solves the problem of recognition difficulties caused by accumulated errors in mechanical transport or board placement deviations, improving the success rate and recognition accuracy of the barcode scanner or recognition lens for various codes (such as 1D and 2D codes).

[0080] Alternatively, the board visual recognition mechanism 43 can be connected to a three-dimensional moving module, which can adjust its three-dimensional position relative to the board, so that the board visual recognition mechanism 43 can obtain a better focusing position and the obtained recognition information is clearer and more accurate.

[0081] Furthermore, an adjustable light source can be provided at the end of the board material identification position 411 that is away from the visual positioning mechanism 42. This light source can be used in conjunction with the visual positioning mechanism 42 to provide sufficient light during visual positioning, so that the visual positioning mechanism 42 can obtain the accurate position of the board material.

[0082] In this invention, the board input mechanism 41 is connected to the board conveying mechanism 20 and is equipped with a dedicated board identification position 411 for the boards. This allows for automatic identification and information collection of the board's identity, enabling the connection between physical conveying and information management, and facilitating the establishment of an information monitoring system for each board. The visual positioning mechanism 42 identifies the position of the board and obtains the relative position between the board and the board identification position 411. This, in conjunction with the first planar moving module, drives the board visual recognition mechanism 43 to move to the optimal identification point, such as directly above the board. This invention can adaptively compensate for positional deviations of the board during conveying, ensuring the clarity and accuracy of barcode scanning or image acquisition, improving the success rate and stability of board information reading, and enabling full traceability of the board. The integrated identification of the board identification device 40 reduces reliance on manual positioning, lowers operational complexity and labor costs, and avoids scanning failures or information errors caused by large physical positioning errors, making it particularly suitable for high-standard quality management scenarios. Furthermore, the real-time uploading of board identification data provides timely and accurate data support for production statistics, quality analysis, and order tracking, contributing to the digitalization of the production process.

[0083] In this embodiment, two spoke-type flipping mechanisms 10 are provided. The sheet material can directly enter the first and second spoke-type flipping mechanisms 10 for buffering. After two flips, the orientation of the sheet material is kept consistent with its original orientation, facilitating subsequent barcode scanning. The guide plate 31 ensures uniformity of the edges during sheet material flipping, preventing jamming during the first and second flips. This significantly reduces the length and volume of the buffering equipment, saving production costs. After buffering, the sheet material is scanned at the sheet material identification position 411 and matched with the MES system, enabling information entry and traceability before product packaging.

[0084] Example 2

[0085] like Figure 1 , Figure 4 as well as Figure 5 As shown, this utility model also provides a sheet metal processing equipment, including:

[0086] Such as the sheet metal conveying device mentioned above;

[0087] It also includes a packaging device 50.

[0088] The sheet material conveying device can be in multiple sets, allowing qualified and unqualified sheets to be conveyed through different independent sets of conveying devices to prevent mixing. The packaging device 50 can be set up one-to-one with multiple sets of sheet material conveying devices to achieve independent and accurate classification and packaging.

[0089] In one alternative implementation, such as Figures 4 to 5 As shown, the packaging device 50 includes a box conveying mechanism 51 and a packaging mechanism 52, wherein the packaging mechanism 52 has a packaging position 523, which is located on the conveying path of the box conveying mechanism 51.

[0090] In this invention, the packaging device 50 specifically includes a box conveying mechanism 51 and a packaging mechanism 52. The packaging position 523 is directly set on the conveying path of the box conveying mechanism 51, allowing packaging to be performed on the conveying path of the box conveying mechanism 51. Spatially, box conveying and board packaging can be integrated; temporally, box conveying and board packaging can be synchronized. Empty box conveying, board loading, and full box output can be completed in a continuous process, reducing the transfer of boards and the possible multiple positioning during transfer, thereby improving the efficiency and stability of the packaging process.

[0091] The packaging position 523 can be configured as an intelligent workstation that can be dynamically adjusted according to the production cycle, box size, or upstream material status. Specifically, a servo drive and positioning system can be integrated into the box conveying mechanism 51, enabling the conveying section carrying the boxes to move and stop precisely within a specific range of the conveying path. The controller can control the box conveying and stop at different coordinate points on the path according to real-time instructions to serve as packaging positions 523, thereby realizing the flexible definition of the packaging position 523. By dynamically adjusting the packaging position 523, a single packaging position 523 can be effectively virtualized into multiple logical workstations, thus providing flexibility for handling different batches and specifications of boxes or responding to fluctuations in upstream processes. For example, when it is necessary to process qualified and unqualified products simultaneously, the system can guide boxes in different states to different points far apart on the path for packaging, avoiding cross-contamination and operational errors.

[0092] Alternatively, a series of sensors, such as weight sensors, visual inspection cameras, photoelectric sensors, or RFID readers, can be integrated and installed around and at the bottom of the packaging station 523. These sensors monitor parameters during the packaging process in real time, including whether the packaging material has been placed inside the box, whether the quantity of material is correct, whether the box itself is damaged, and whether the identification information of the box and the material matches. All data is uploaded to the controller in real time for analysis and decision-making. This enables real-time online inspection and data traceability of packaging quality, preventing packaging errors such as omissions, over-packaging, and misplacement from flowing into downstream processes, thus improving the reliability of the finished products.

[0093] In one alternative implementation, such as Figure 4 As shown, the box conveying mechanism 51 includes:

[0094] The system includes a box input mechanism 511 with a box identification position 5111; a box visual recognition mechanism 512 connected to a second planar moving module, which can identify the information of the box to determine whether it is used to pack qualified boards or unqualified boards, and can match the board information and box information through a controller to prevent mis-packing and omissions. The second planar moving module allows the box visual recognition mechanism 512 to be positioned corresponding to the box identification position 5111. The second planar moving module can be a linear moving module, positioned above the box input mechanism 511, which can drive the box visual recognition mechanism 512 to identify the boxes on the box input mechanism 511; and a box lifting mechanism 513 located at the output end of the box input mechanism 511, with the packing position 523 located on the lifting path of the box lifting mechanism 513.

[0095] This invention achieves automated box supply, identification, and precise positioning. The box input mechanism 511 supplies empty boxes. Driven by the second planar moving module, the box visual recognition mechanism 512 aligns with the box identification position 5111 and reads the marking information on the box, ensuring that the information of each box is recorded and matched with system information. This enables information binding between the board material and the box, facilitating a traceable production process. The box lifting mechanism 513 receives the identified empty box and lifts it to the preset packaging height, i.e., the packaging position 523, preparing it for the material handling mechanism 521 to pick up and place the board material. This invention ensures the consistency of information between the board material and the box, eliminates the possibility of misuse of the wrong box, and improves the standardization and automation level of the packaging process.

[0096] The box visual recognition mechanism 512 can be integrated into the second planar moving module, the box lifting mechanism 513 can be disposed on the end side of the box input mechanism 511, and the packaging position 523 can be located at the top of the box lifting mechanism 513. The box can be transported to the box lifting mechanism 513 at the maximum stroke of the box input mechanism 511, and the box can be transported to the packaging position 523 at the maximum stroke of the box lifting mechanism 513.

[0097] Alternatively, pre-alignment and correction functions can be integrated into the box input mechanism 511. A box identification position 5111 is provided on the conveying path of the box input mechanism 511, and an active correction device guided by a sensor (such as a finely adjustable pulley system or push rod mechanism) is set upstream of the box identification position 5111. When a box enters the input mechanism, the pre-sensor of the box identification position 5111 initially judges its position and angle deviation. The active correction device then activates, correcting the posture of the box before it reaches the box identification position 5111. Through this pre-position active correction, random posture errors generated during the conveying and accumulation process can be eliminated, ensuring that each box is in the same position and posture when it reaches the box identification position 5111 and the subsequent packaging position 523. This improves the reading speed and success rate of the box vision recognition mechanism 512, providing a stable and reliable environment for the picking and placing operations of the packaging mechanism 52.

[0098] In addition, a distributed drive conveyor unit (such as a servo motor-based magnetic levitation or precision belt segment) can be used to construct the box input mechanism 511. Specifically, each conveyor unit has its own drive and control, which are coordinated and scheduled by the upper-level controller. The box identification position 5111 can be formed by multiple units working together. The box vision recognition mechanism 512 and the second planar movement module are integrated above the distributed drive conveyor unit, and the box lifting mechanism 513 is connected to the last conveyor unit. The distributed drive allows the position, speed, and spacing of each box to be independently and precisely controlled while it is being conveyed. It can realize complex synchronization, tracking, accumulation, and precise start-stop functions, optimize the logistics cycle, and enable the boxes to accelerate, decelerate, and stop smoothly and without impact at the box identification position 5111 and the packaging position 523.

[0099] In one alternative implementation, such as Figure 5 As shown, the packaging mechanism 52 includes:

[0100] A material handling mechanism 521 is disposed between the sheet material input mechanism 41 and the packaging position 523; a box output mechanism 522 is disposed downstream of the material handling mechanism 521, which allows finished products to be output from the packaging position 523, and the upstream of the box output mechanism 522 is connected to the packaging position 523. The material handling mechanism 521 can be a four-axis robot, and both the sheet material input mechanism 41 and the packaging position 523 are within the working range of the robot.

[0101] In this invention, the sheet material input mechanism 41 and the packaging position 523 are positioned within the working range of the material handling mechanism 521, allowing the sheet material to be placed into the box at the packaging position 523. The information of the picked-up sheet material and the box is matched; qualified sheet material is placed into the box containing pre-stored qualified products, and unqualified sheet material is placed into the box containing pre-stored unqualified products, thus completing the precise conversion of the sheet material from individual to packaged finished product. The box output mechanism 522 can output the packaged finished product. The entire packaging process of this invention requires no manual intervention, reducing quality fluctuations caused by human factors, ensuring the consistency and traceability of packaging quality, and enabling automated connection with downstream logistics or warehousing links.

[0102] The box output mechanism 522 may include a qualified conveyor line and an unqualified conveyor line, which respectively convey the qualified and unqualified packaged boards. It enables classified scanning and unloading. The conveyor lines can be used together or separately, improving equipment utilization and adaptability. It should be noted that each conveyor line can only package a fixed type of qualified or unqualified product, thus preventing mixing issues.

[0103] A replaceable weighing sensor can be integrated into the box output mechanism 522, which carries the full-loaded boxes. Before output, the boxes can be weighed and recorded at the output mechanism 522, and compared with the theoretically calculated weight (based on the weight of a single item and the quantity placed). The comparison result (pass / fail) will be automatically bound to the box's identification information (such as a barcode) and uploaded to the information management system. Non-contact final inspection of the packaging results is possible. Based on the weight comparison results, packaging errors that are difficult to identify visually, such as missing, overfilled, or misplaced (products of different weights), can be detected promptly. This process requires no additional operator intervention, does not affect the production cycle, and all data is automatically bound and uploaded, achieving complete traceability of production information.

[0104] Alternatively, multiple sensors and cameras can be installed around the material handling mechanism 521 and the packaging station 523 to collect data in real time, such as the movement posture of the material handling mechanism 521, the gripping status of the sheet metal, and the stacking status inside the box. This data is integrated by an AR processing unit and superimposed onto the real-world video feed as a virtual image, displayed on a remote monitoring screen or AR glasses. Operators can intuitively see, through the remote monitoring screen or AR glasses, information such as the predetermined gripping path, real-time gripping force feedback values, the deviation between the theoretical and actual placement of the sheet metal inside the box, and predictive maintenance information for the material handling mechanism 521 itself (e.g., joint wear). Through AR visualization, operators can understand the equipment's operating status in real time, identify the root causes of problems such as gripping deviation and uneven stacking, and reduce downtime for troubleshooting.

[0105] This invention ensures first-in-first-out (FIFO) board production, simplifies the structure, reduces space requirements, improves transmission smoothness, enhances scanning accuracy, increases the box output mechanism 522, and extends packaging buffer time, thereby improving the overall pass rate and reducing production and maintenance costs. In summary, this invention improves the overall pass rate and reduces production and maintenance costs.

[0106] This invention employs a spoke-type flipping mechanism, which has a simplified structure, greatly saving factory space and reducing production and maintenance costs. The requirement for scanning both sides of the product can be met by increasing the number of spoke-type flipping mechanisms 10. The spoke-type flipping mechanism 10 ensures first-in, first-out (FIFO) product flow to meet this process requirement. This invention uses an integrated upper and lower front and rear guide plate 31, avoiding card and stacking issues and improving product transport smoothness. The spoke-type flipping mechanism 10 and the sheet metal identification device 40 are designed independently, improving equipment utilization and adaptability. The sheet metal conveying device and packaging device 50 are combined sequentially into a single process, achieving stable, efficient, and low-cost process requirements for the product.
