Description

Technical Field

[0001] This utility model relates to the field of tool storage technology, and in particular to an image detection mechanism and a tool storage system. Background Technology

[0002] CNC machine tools have the advantages of high machining accuracy, high production efficiency and good versatility. During the machining process of CNC machine tools, various types of cutting tools are required. Therefore, tool storage cabinets are usually equipped to store the cutting tools for easy management.

[0003] In related technologies, tool storage cabinets are equipped with tool pick-and-place racks. Tools to be stored are placed on these racks, and internal components such as robotic arms move the tools from the pick-and-place racks to the storage racks. To improve the intelligence of tool management, the tool storage cabinets also include a wear recognition module, which includes, but is not limited to, an image capturing mechanism and an image processing module. The image capturing mechanism photographs the cutting edge of the tools on the pick-and-place racks and transmits the photograph to the image processing module. The image processing module determines the wear condition of the tool based on the photograph and then controls the robotic arm or other components to place the tool on the appropriate storage rack. The position of the cutting edge varies; for example, some tools have the cutting edge located on the periphery, while others have it located on the end face. Therefore, to ensure that the image capturing mechanism can successfully photograph the cutting edge, a complex drive system is required. This drive system not only needs to move the image capturing mechanism forward, backward, left, and right but also rotate it, resulting in a complex drive system structure that occupies a significant amount of space.

[0006] Based on the above concept, the technical solution adopted in this application is:

[0007] Image detection agencies include:

[0008] A tool holder assembly, comprising a first tool holder, a second tool holder, and a third tool holder, wherein the first tool holder, the second tool holder, and the third tool holder are spaced apart along a first direction, the first tool holder and the second tool holder are both cylindrical, and the axial direction of the first tool holder intersects the axial direction of the second tool holder, and the third tool holder is provided with a tool holder groove;

[0009] An image acquisition component is disposed on one side of the tool holder assembly in a second direction. The image acquisition component is used to acquire surface images of the tools on the first tool holder, the second tool holder, or the third tool holder. The second direction intersects with the first direction.

[0010] A driving component is connected to one of the tool holder assembly and the image acquisition assembly, and is configured to drive the tool holder assembly or the image acquisition assembly to move upward in the first direction, the second direction, and a third direction, wherein the third direction intersects both the first direction and the second direction.

[0011] In one or more embodiments of this application, the tool holder groove is a V-shaped groove.

[0012] In one or more embodiments of this application, the third tool holder is provided with a support surface, which is a plane.

[0013] In one or more embodiments of this application, the driving component includes a first driving group and a second driving group, the second driving group being connected to the first driving group, and the first driving group being used to drive the second driving group to move along a second direction and a third direction. The image acquisition component or the tool holder component is connected to the first driving group, and the first driving group is used to drive the first of the image acquisition component and the tool holder component to move along the first direction. The second of the image acquisition component and the tool holder component is disposed on the second driving group.

[0014] Alternatively, the driving assembly may include a first driving group and a second driving group, wherein the first driving group is used to drive the first of the image acquisition assembly and the tool holder assembly to move along the first direction, and the second driving group is used to drive the second of the image acquisition assembly and the tool holder assembly to move along the second direction and the third direction.

[0015] In one or more embodiments of this application, the first drive group includes a drive member, a lead screw, and a moving block. The lead screw is connected to the output end of the drive member and extends along a first direction. The moving block is sleeved on the lead screw and screwed to the lead screw. The image acquisition component or the tool holder component is connected to the moving block.

[0016] In one or more embodiments of this application, the driving component further includes a first connecting plate, a second connecting plate, and a third connecting plate. The first connecting plate extends along the third direction and is connected to the moving block at one end in the third direction. The second connecting plate extends along the second direction and is connected to the moving block. The third connecting plate extends along the third direction and is connected at one end to the second connecting plate. The image acquisition component includes a processing module and a lens module disposed opposite to each other. The processing module is connected to the first connecting plate, and the lens module is disposed on the third connecting plate.

[0017] In one or more embodiments of this application, the drive assembly further includes a fourth connecting plate and a fifth connecting plate, the fourth connecting plate being connected to the second drive group, and the fifth connecting plate being connected to the end of the fourth connecting plate opposite to the second drive group, wherein the first tool post, the second tool post, and the third tool post are all disposed on the fifth connecting plate.

[0021] The beneficial effects of this application are:

[0022] In the image detection mechanism and tool storage system, by setting up a first tool holder, a second tool holder, and a third tool holder, the tool can be placed on different tool holders when the cutting edge position is different. When the driving component drives the image acquisition component or the tool holder component to move in the first direction, the image acquisition component can be aligned with different tool holders, thereby acquiring the surface image of the tool. When the driving component drives the image acquisition component or the tool holder component to move in the second direction, the distance between the image acquisition component and the tool can be adjusted, thereby acquiring the surface image of the tool more clearly. When the driving component drives the image acquisition component or the tool holder component to move in the third direction, the relative position of the image acquisition component and the tool in the third direction can be adjusted, thereby aligning with the cutting edge. In this way, the relative position of the image acquisition component and the tool holder component in space can be adjusted to adapt to the height and shooting angle requirements of different tools. There is no need to set up space around the tool holder component for the image acquisition component to rotate, nor is there a need to set up a rotation driving component, thereby reducing the structural complexity of the image detection mechanism. Moreover, the image detection mechanism occupies less space, which is conducive to the miniaturization of the image detection mechanism while ensuring the detection function.

[0039] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] This embodiment provides an image detection mechanism with a simple structure and small footprint. The image detection mechanism provided in this embodiment can be applied to tool storage systems, requiring less space and thus facilitating the miniaturization of the tool storage system.

[0041] For example, such as Figures 1 to 6As shown, the image detection mechanism includes a tool holder assembly 1, an image acquisition assembly 2, and a drive assembly 3. The tool holder assembly 1 is used to fix the tool, the image acquisition assembly 2 is used to acquire surface images of the tool, and the drive assembly 3 is used to drive one of the image acquisition assembly 2 and the tool holder assembly 1 to move relative to the other, thereby adjusting the relative position of the image acquisition assembly 2 and the tool holder, so that the image acquisition assembly 2 can acquire surface images of specific locations on the tool. For example, the image acquisition assembly 2 is used to acquire images of the cutting edge of the tool, and the wear condition of the tool can be determined based on the images. Based on the wear condition of the tool and the operating conditions, the remaining service life of the tool can be calculated.

[0042] In this embodiment, as Figure 1 As shown, the tool holder assembly 1 includes a first tool holder 11, a second tool holder 12, and a third tool holder 13. The first tool holder 11, the second tool holder 12, and the third tool holder 13 are spaced apart along a first direction X. The specific structures of the first tool holder 11, the second tool holder 12, and the third tool holder 13 are different, thereby enabling the support of different tools. For example, as... Figure 1 and Figure 2 As shown, both the first tool holder 11 and the second tool holder 12 are cylindrical, and these cylindrical shapes can be used to support cylindrical cutting tools. Furthermore, the axial direction of the first tool holder 11 intersects the axial direction of the second tool holder 12. Thus, after the first tool holder 11 and the second tool holder 12 support the cutting tool, the cutting edge of the tool can face the image acquisition component 2, thereby facilitating the acquisition of images at the cutting edge. Figure 3 As shown, the third tool holder 13 in this embodiment is provided with a tool holder groove 131, which is a semi-enclosed structure. Therefore, the tool holder groove 131 enables the third tool holder 13 to carry irregularly shaped tools, making it more versatile and applicable.

[0043] In this embodiment, the image acquisition component 2 is disposed on one side of the tool holder assembly 1 in the second direction Y. That is, the image acquisition component 2 and the tool holder assembly 1 are disposed opposite to each other in the second direction Y, thereby facilitating the acquisition of the surface image of the tool. Exemplarily, the image acquisition component 2 is used to acquire the surface image of the tool on the first tool holder 11, the second tool holder 12, or the third tool holder 13. When a tool is mounted on the first tool holder 11, the image acquisition component 2 uses the surface image of the tool on the first tool holder 11; when a tool is mounted on the second tool holder 12, the image acquisition component 2 uses the surface image of the tool on the second tool holder 12; and when a tool is mounted on the third tool holder 13, the image acquisition component 2 uses the surface image of the tool on the third tool holder 13.

[0044] Because the first tool holder 11, the second tool holder 12, and the third tool holder 13 are positioned differently relative to the image acquisition component 2, a driving component 3 is required to adjust the relative position of the image acquisition component 2 with respect to the first tool holder 11, the second tool holder 12, and the third tool holder 13. Exemplarily, the driving component 3 is connected to one of the tool holder assembly 1 and the image acquisition component 2, and is configured to drive either the tool holder assembly 1 or the image acquisition component 2 to move in the first direction X, the second direction Y, and the third direction Z, so that the image acquisition component 2 is opposite to the tool holder on which the tool is placed, thereby acquiring a surface image of the tool. The first direction X, the second direction Y, and the third direction Z intersect each other. In other embodiments, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0045] In use, the image detection mechanism sets up a first tool holder 11, a second tool holder 12, and a third tool holder 13 with different structures or shapes, places the cutting tool on the corresponding tool holder, and then adjusts the drive assembly 3 to drive the tool holder assembly 1 to move in the first direction X and the second direction Y, thereby adjusting the relative positional relationship between the image acquisition assembly 2 and the cutting tool, so that the image acquisition assembly 2 can acquire the surface image of the cutting tool. In some embodiments, such as Figure 1 As shown, the first tool holder 11 has its axis oriented in the second direction Y, allowing it to be used to fix or support a tool with its cutting edge positioned on its end face, so that the cutting edge faces the image acquisition component 2. The second tool holder 12 has its axis oriented in the third direction Z, allowing it to be used to fix or support a tool with its cutting edge positioned on its circumferential side, so that the cutting edge faces the image acquisition component 2.

[0046] The image detection mechanism provided in this embodiment, by setting a first tool holder 11, a second tool holder 12, and a third tool holder 13, allows the tool to be placed on different tool holders when the blade position is different. When the driving component 3 drives the image acquisition component 2 or the tool holder assembly 1 to move in the first direction X, the image acquisition component 2 can be positioned opposite different tool holders, thereby enabling the acquisition of the tool's surface image. When the driving component 3 drives the image acquisition component 2 or the tool holder assembly 1 to move in the second direction Y, the distance between the image acquisition component 2 and the tool can be adjusted, thereby enabling a clearer acquisition of the tool's surface image. When the tool holder assembly 1 moves in the third direction Z, it can adjust the relative position of the image acquisition assembly 2 and the tool in the third direction Z, so that they can face the blade. This realizes the adjustment of the relative position of the image acquisition assembly 2 and the tool holder assembly 1 in space to adapt to the height and shooting angle requirements of different tools. There is no need to set up space around the tool holder assembly 1 for the image acquisition assembly to rotate, nor is there a need to set up rotation drive components. This reduces the structural complexity of the image detection mechanism. In addition, the image detection mechanism occupies less space, which is conducive to the miniaturization of the image detection mechanism while ensuring the detection function.

[0047] In some alternative embodiments, such as Figure 3 As shown, the tool holder groove 131 is a V-shaped groove. By setting the V-shaped groove, it can be used for cutting tools with prismatic tips, such as milling inserts or turning inserts. One corner of the prismatic insert is inserted into the V-shaped groove, and the concave-convex fit allows the tool holder groove 131 to better support the cutting tool.

[0048] It is understood that the tool holder groove 131 can also be a groove of other shapes, such as a square groove, an arc groove, etc., and this embodiment does not limit it.

[0049] In at least one possible implementation, such as Figure 4 As shown, the third tool holder 13 is provided with a support surface 132, wherein the support surface 132 is a plane. By providing the support surface 132, the third tool holder 13 can support tools with a plane. That is, as long as the tool has a plane, it can be supported by the support surface 132. For example, milling inserts or turning inserts, when their bottom surface is flat, can be placed on the support surface 132 to keep them stable, thereby capturing the surface image of the tool, further improving the application range of the third tool holder 13. In some embodiments, the support surface 132 is a surface extending along the plane containing the first direction X and the second direction Y.

[0050] In some embodiments, the tool holder groove 131 is provided on the support surface 132. When dealing with tools with irregular structures, the tool holder groove 131 can also provide clearance, so that the tool is more stably supported on the support surface 132.

[0051] The specific structure of the driving component 3 can be various. This embodiment provides a driving component 3 as an example, but it is not limited thereto.

[0052] In some embodiments, the driving component 3 includes a first driving group 31 and a second driving group 32. The second driving group 32 is connected to the first driving group 31, and the first driving group 31 drives the second driving group 32 to move along a second direction Y and a third direction Z. An image acquisition component 2 or a tool holder component 1 is connected to the first driving group 31, and the first driving group 31 drives the first of the image acquisition component 2 and the tool holder component 1 to move along a first direction X, while the second of the image acquisition component 2 and the tool holder component 1 is disposed on the second driving group 32.

[0053] In other embodiments, such as Figure 3 As shown, the drive assembly 3 includes a first drive group 31 and a second drive group 32. The first of the image acquisition assembly 2 and the tool holder assembly 1 is connected to the first drive group 31, and the first drive group 31 drives the first assembly to move in a first direction X. The second of the image acquisition assembly 2 and the tool holder assembly 1 is connected to the second drive group 32, and the second drive group 32 drives the second assembly to move in a second direction Y and a third direction Z.

[0054] Both of the above embodiments can adjust the relative positions of the image acquisition component 2 and the tool holder component 1 in space, and can be flexibly selected according to needs.

[0055] In some optional embodiments, this embodiment provides a first drive group 31, exemplarily, such as... Figure 3 As shown, the first drive assembly 31 includes a drive member 311, a lead screw 312, and a moving block 313. The lead screw 312 is connected to the output end of the drive member 311 and extends along the first direction X. The moving block 313 is sleeved on the lead screw 312 and screwed to it. When the drive member 311 drives the lead screw 312 to rotate, the moving block 313 moves relative to the lead screw 312 along the first direction X. The image acquisition assembly 2 or the tool holder assembly 1 is connected to the moving block 313, enabling the image acquisition assembly 2 or the tool holder assembly 1 to move in the first direction X.

[0056] Further optional, such as Figure 6As shown, the driving assembly 3 also includes a first connecting plate 33, a second connecting plate 34, and a third connecting plate 35. The first connecting plate 33 extends along a third direction Z, and one end of the first connecting plate 33 in the third direction Z is connected to the moving block 313. The second connecting plate 34 extends along a second direction Y and is connected to the moving block 313. The third connecting plate 35 extends along a third direction Z, and one end of the third connecting plate 35 is connected to the second connecting plate 34. The image acquisition assembly 2 includes a processing module 21 and a lens module 22 arranged opposite to each other. The processing module 21 is connected to the first connecting plate 33, and the lens module 22 is disposed on the third connecting plate 35. By setting the first connecting plate 33, the second connecting plate 34, and the third connecting plate 35, the image acquisition assembly 2 is easily supported and fixed, and the first driving group 31 drives the image acquisition assembly 2 to move in the first direction X. The structure is relatively simple and the cost is low.

[0057] In some optional embodiments, the drive assembly 3 further includes a fourth connecting plate 36 and a fifth connecting plate 37. The fourth connecting plate 36 is connected to the second drive group 32, and the fifth connecting plate 37 is connected to the end of the fourth connecting plate 36 opposite to the second drive group 32. The first tool holder 11, the second tool holder 12, and the third tool holder 13 are all disposed on the fifth connecting plate 37.

[0058] It should be noted that the second drive group 32 can drive the fourth connecting plate 36 to move in the third direction Z, or it can choose not to drive the fourth connecting plate 36 to move in the third direction Z; this embodiment does not limit this. When the second drive group 32 drives the third connecting plate 35 to move in the third direction Z, for example, the second drive group 32 may include a first cylinder (not shown in the figure), and the fourth connecting plate 36 may be connected to the output end of the first cylinder, with the first cylinder driving the fourth connecting plate 36 to move in the third direction Z. The second drive group 32 can also drive the fourth connecting plate 36 to move in the first direction X and / or the second direction Y, which can also be achieved by a cylinder, or by other linear drive components such as a linear motor; this embodiment does not limit this. It is understood that the second drive group 32 can also drive the first drive group 31 to move in the second direction Y; this embodiment does not limit this. In some other embodiments, the second drive group 32 may include a lead screw and a screw block, the screw block being screwed to the lead screw, the lead screw being driven to rotate by a motor or other components, thereby causing the screw block to move along the third direction Z, and the fourth connecting plate 36 may be connected to the screw block to realize the movement of the fourth connecting plate 36 in the third direction Z.

[0059] In at least one possible implementation, such as Figure 5 and Figure 6As shown, the fifth connecting plate 37 is disposed opposite to the image acquisition component 2 in the second direction Y, and is used to limit the lower limit of the distance between the image acquisition component 2 and the tool holder assembly 1. That is, the fifth connecting plate 37 is used to limit the minimum distance between the image acquisition component 2 and the tool holder assembly 1 in the second direction Y, thereby avoiding the problem of the tool scratching the lens module 22 and improving reliability. In this embodiment, when the image acquisition component 2 and the tool holder assembly 1 approach each other, the fifth connecting plate 37 gradually approaches the lens module 22. If an abnormal situation occurs and the two cannot stop approaching each other, the fifth connecting plate 37 will contact the lens module 22, while the side of the tool facing the lens module 22 in the second direction Y does not exceed the fifth connecting plate 37, so the tool will not contact the lens module 22, thereby preventing the problem of scratching the lens module 22.

[0060] In some embodiments, the image detection mechanism further includes a light source module (not shown in the figure), which is disposed on the fifth connecting plate 37. By disposing the light source module on the fifth connecting plate 37, when the fifth connecting plate 37 moves, it will drive the light source module and the tool holder assembly 1 to move together, so that the light from the light source module can always fall on the tool holder assembly 1 and then illuminate the tool, making the image captured by the lens module 22 clearer and thus improving the accuracy of tool wear detection.

[0061] This embodiment also provides a tool storage system, which has the advantage of simple structure and meets the requirements of miniaturization.

[0062] The tool storage system includes the aforementioned image detection mechanism, and also includes a cabinet, a human-machine interface module (HMI) housed within the cabinet, and a device access device. The image detection mechanism and the device access device are both communicatively connected to the HMI module. The device access device is used for placing and retrieving tools from the first tool holder 11, the second tool holder 12, or the third tool holder 13.

[0063] In some alternative embodiments, the tool storage system can also manage the remaining life of each tool, preventing borrowed tools from being used in processes beyond their remaining life.

[0064] In some embodiments, the tool storage system can be divided into a human-machine control module, a tool remaining life prediction module, a tool current wear identification module, and a signal communication module according to its function. This embodiment also provides an intelligent storage method applied to the tool storage system, specifically including: when a used or brand-new tool is placed in the intelligent tool cabinet, the administrator inputs the basic information of the tool (such as tool model, brand, etc.) and then performs steps 1 to 3 in sequence.

[0065] Step 1: Identify the current wear of the cutting tool using an image detection mechanism. The operator places the cutting tool on the corresponding tool holder, and then drives the image acquisition component 2 and the tool holder component 1 to move relative to each other via the drive component 3. This allows the image acquisition component 2 to capture a photograph of the cutting edge of the cutting tool. The image acquisition component 2 can automatically identify the wear area of ​​the cutting tool, output the corresponding wear parameters (such as the back face wear value VB) and the wear type (edge ​​chipping, cracks, etc.), and generate the wear value and wear level results.

[0066] Step 2: Predict tool life based on Step 1. The tool life prediction module uses a library of multiple process life models built into historical tool data. The tool wear parameters identified in Step 1 are input and processed through various operating condition models to output the remaining tool life value under different operating conditions. The operating condition model selection process can be set by the user or completed automatically by the system.

[0067] Step 3 involves managing the information of the incoming tools for future retrieval. The human-machine interface module (HMI) provides full lifecycle digital management of all tools stored in the tool cabinet, using a QR code recognition unit to automatically read and update the unique tool identifier. The module's core data structure consists of three parts: a basic tool information table, a usage record table, and a lifespan prediction table.

[0068] It should be noted that the basic tool information table includes tool ID (unique code, QR code binding), tool type, material and coating type, size specifications, machinable parameters, machinable workpieces, and production batch.

[0069] The usage records include: cumulative cutting time and cumulative machining length, tool status (in stock, in use, ready to be scrapped), and wear parameters after each machining operation (uploaded by the wear acquisition module).

[0070] The life prediction table includes: the predicted remaining life value for different operating conditions (provided by the life prediction module), tool change thresholds, and early warning prompts.

[0071] In this embodiment, the intelligent retrieval method includes:

[0072] Step 11: The operator of the machining task inputs tool requirements and usage information, including workpiece material type, process type, and estimated machining time or length, into the visual interactive terminal of the tool cabinet.

[0073] Step 12: Retrieve the tool life prediction table data from the human-machine control module and filter according to the following conditions: remaining tool life ≥ required processing time (or processing length); tool type matches process type; tool status is "available in stock". For different batches of tools of the same tool type, prioritize the tool with the shortest remaining life that still meets the processing requirements, so as to exhaust its remaining usage length first.

[0074] Step 13: After the tool is retrieved and used, the tool cabinet management system and the CNC machine tool equipment perform signal conversion and forwarding through the edge terminal (industrial gateway), continuously track the usage status of the borrowed tool, and at the same time, the tool usage data can be transmitted back to the tool cabinet system to optimize and upgrade the built-in model of the tool remaining life prediction module.

[0075] Before external cutting tools enter the tool cabinet, they need to be imaged by the image acquisition component 2. During the inspection process, the cutting tools to be inspected are fixedly mounted on the first tool holder 11, the second tool holder 12, or the third tool holder 13, depending on their type. Taking a milling cutter as an example, the milling cutter is fixed on the first tool holder 11 to be positioned and kept stable, thus avoiding displacement errors during the imaging process. The lead screw 312 is driven by the drive component 311 (including but not limited to a motor) to achieve precise linear movement of the processing module 21 and the lens module 22 along the first direction X, thereby enabling multi-segment imaging of the cutting tool at different positions and angles. The second drive group 32 can drive the fourth connecting plate 36 to make fine adjustments in the third direction Z, thereby realizing fine adjustments of the tool holder assembly in the third direction Z to adapt to the height and imaging angle requirements of different cutting tools.

[0076] During the movement of the image acquisition component 2, the lens module 22 performs high-resolution imaging of the cutting edge area of ​​the tool. Combined with a stable light source module, this ensures consistent brightness and clarity across different shooting positions. The images acquired by the image acquisition component 2 are transmitted in real-time to the image recognition software for subsequent preprocessing, segmentation, and wear recognition processes, achieving automated detection of tool wear conditions. This mechanism, through the high-precision positioning capability of the lead screw 312 drive and its multi-axis linkage design, enables high-precision multi-view tool imaging.
