[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0038] This application provides a visual inspection device for cutting tools. By incorporating a line scan camera assembly and a first adjustment component connected to the line scan camera assembly, and an area scan camera assembly and a second adjustment component connected to the area scan camera assembly, the device enables the installation and automatic position adjustment of both the line scan and area scan camera assemblies. After the cutting tool is fixed, the line scan and area scan camera assemblies sequentially acquire images of the tool's circumferential cutting edge and end face, allowing for the assessment of tool wear. This solves the problem of low yield rates caused by the difficulty of visually detecting tool wear by operators in traditional methods. This device offers comprehensive and effective tool inspection. The device features a reasonable structural design, high automation, high inspection efficiency, and high accuracy. Furthermore, for the position adjustment of the area scan camera assembly, the translational and rotational degrees of freedom of the assembly are broken down into independently adjustable platform motions, ensuring that adjustments to the degrees of freedom of each component do not interfere with each other, thus improving the flexibility of position adjustment.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1This is an isometric drawing of a tool vision inspection device provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows a front view of a tool vision inspection device. This device can be used to inspect tool surfaces and may include: a line scan camera assembly 100, a first adjustment assembly 200, an area scan camera assembly 300, a second adjustment assembly Q, a third position adjuster 600, a pneumatic chuck, a collet 700, a first lifting slide rail drive 800, a first adapter 900, a second lifting slide rail drive 1000, and a second adapter 1100.

[0040] The line scan camera assembly 100 can be arranged along the first direction f1 with the tool A, and the photosensitive surface of the line scan camera assembly 100 can be set facing the circumferential side of the tool. The first adjustment assembly 200 can be connected to the line scan camera assembly 100. Here, the driving end of the first adjustment assembly 200 can be connected to the side of the line scan camera assembly 100 and can be used to drive the line scan camera assembly 100 to move, so as to ensure that the relative positional relationship between the line scan camera assembly 100 and the tool A meets the requirements for image acquisition of the tool surface.

[0041] The area scan camera assembly 300 can be arranged with the cutting tool along a second direction f2 perpendicular to the first direction f1, and the photosensitive surface of the area scan camera assembly 300 can be positioned facing the end of the cutting tool A. The second adjustment assembly Q can be connected to the side of the area scan camera assembly 300.

[0042] The first adjustment component 200 can be used to drive the line scan camera assembly 100 to move relative to the cutter A, so that the circumferential side of the cutter A is imaged on the photosensitive surface of the line scan camera assembly 100; the second adjustment component Q is used to drive the area scan camera assembly 300 to rotate relative to the cutter A about a first direction f1, about a direction perpendicular to the first direction f1 and perpendicular to the optical axis of the area scan camera assembly 300, and to move along a second direction f2, so that the end of the cutter A is imaged on the photosensitive surface of the area scan camera assembly 300.

[0043] In this application, the second adjustment component Q may include: a first angle adjuster 400 and a second position adjuster 500. The rotating end D1 of the first angle adjuster 400 in the tool vision inspection device may be connected to the side of the area array camera assembly 300, and the first angle adjuster 400 may be used to drive the area array camera assembly 300 to rotate around the central axis L1 (i.e., the first central axis L1) of the rotating end D1 of the first angle adjuster 400.

[0044] The driving end of the second position adjuster 500 in the tool vision inspection equipment can be connected to the bottom of the first angle adjuster 400, and the second position adjuster 500 can be used to drive the first angle adjuster 400 to rotate around the central axis L2 (i.e., the second central axis) of the driving end of the second position adjuster 500, and to drive the first angle adjuster 400 to move along the second direction f2. Here, the central axis of the driving end of the second position adjuster 500 can be parallel to the first direction f1. The central axis of the rotating end of the first angle adjuster 400 can be perpendicular to the central axis of the driving end of the second position adjuster 500 and perpendicular to the optical axis of the area scan camera assembly 300.

[0045] The third position adjuster 600 in the tool vision inspection equipment may have a rotating shaft (not shown in the figure), a pneumatic chuck may be fixed on the rotating shaft, and a collet 700 may be installed inside the pneumatic chuck. The pneumatic chuck may be configured to drive the collet 700 to deform in order to clamp the tool A. For example, the third position adjuster 600 can drive the pneumatic chuck to move along a first direction f1 and a second direction f2 via the rotating shaft to adjust the position of the tool A relative to the line scan camera assembly 100 and the area scan camera assembly 300. Alternatively, the third position adjuster 600 can drive the rotating shaft to rotate, thereby causing the pneumatic chuck and the collet 700 with the tool mounted to rotate simultaneously.

[0046] In the tool vision inspection equipment, both the first lifting slide rail drive 800 and the second lifting slide rail drive 1000 can extend along a first direction f1. A first adapter 900 can connect to a first adjustment component 200, and a second adapter 1100 can connect to a second position adjuster 500. The first lifting slide rail drive 800 can be configured to be driveably connected to the first adapter 900, thereby moving the first adapter 900 and the first adjustment component 200 along the extending direction of the first lifting slide rail drive 800. The second lifting slide rail drive 1000 can be configured to be driveably connected to the second adapter 1100, thereby moving the second adapter 1100 and the second position adjuster 500 along the extending direction of the second lifting slide rail drive 1000. Thus, as the first lifting slide rail drive 800 drives the first adjusting component 200 to move along the extension direction of the first lifting slide rail drive 800, it can simultaneously drive the line scan camera component 100 to move, thereby adjusting the object distance between the line scan camera component 100 and the tool A. Similarly, as the second lifting slide rail drive 1000 drives the second position adjuster 500 to move along the extension direction of the second lifting slide rail drive 1000, it can simultaneously drive the area scan camera component 300 to move, thereby adjusting the overall position of the area scan camera component 300 along the extension direction of the second lifting slide rail drive 1000.

[0047] For example, this section illustrates the process of a tool vision inspection device inspecting the surface of a tool:

[0048] First, place the tool to be tested in the test tray.

[0049] Then, a collaborative robot or a person picks up the tool to be tested and places it in the collet inside the pneumatic chuck. The pneumatic chuck is then controlled to drive the collet to clamp the tool.

[0050] Subsequently, the third position adjuster drives the pneumatic chuck and collet to move to the end-face imaging position, triggering the area scan camera assembly to acquire image information of the tool's end face and save the acquired image information. It should be noted that during this process, the first angle adjuster and the second position adjuster need to adjust the position of the area scan camera assembly to ensure the best imaging field of view of the tool end face within the area scan camera assembly.

[0051] Subsequently, the area scan camera assembly is shut down. The third position adjuster drives the pneumatic chuck and collet to move to the imaging position on the circumferential cutting edge side. The rotation axis of the third position adjuster rotates, causing the tool to rotate at a certain angle, triggering the line scan camera assembly to acquire image information of the tool's circumferential cutting edge side and save the acquired image information. It should be noted that during this process, the first adjustment assembly needs to adjust the position of the line scan camera assembly to ensure the optimal imaging field of view of the tool's circumferential cutting edge within the line scan camera assembly.

[0052] Subsequently, relevant image recognition and detection algorithms were used to detect defects on the tool surface and obtain the tool detection results.

[0053] Finally, turn off the line scan camera assembly, remove the tool from the collet and place it into the corresponding tray to complete the tool inspection.

[0054] Please refer to Figure 3 and Figure 4 , Figure 3 This is an isometric view of another tool vision inspection device provided in this application embodiment. Figure 4This is a partial structural schematic diagram of a tool vision inspection device provided in an embodiment of this application. The third position adjuster 600 may include: a first drive motor 601, a transmission mechanism 602, and a rotating shaft (not shown in the figure). The transmission mechanism 602 can be connected to both the output shaft of the first drive motor 601 and the rotating shaft, and the first drive motor 601 can drive the rotating shaft to rotate via the transmission mechanism 602. Additionally, the third position adjuster 600 may also include: a second drive motor 603, a lead screw 604, and a support member 605. The output shaft of the second drive motor 603 can be connected to the lead screw 604, and the support member 605 is sleeved on and driven by the lead screw 604. The extension direction of the lead screw 604 can be parallel to the second direction f2. The transmission mechanism 602 is fixed to the support member 605. In this way, the second drive motor 603, together with the lead screw 604 and the support 605, can drive the transmission mechanism 602, the first drive motor 601 and the rotating shaft to move along the second direction f2, so as to adjust the position of the collet 700 in the second direction f2.

[0055] In the embodiments of this application, such as Figure 3 As shown, the line scan camera assembly 100 may include: a line scan camera 101, a fixed-focus lens 102 and a coaxial light source 103 arranged sequentially along the first direction f1. The line scan camera 101 may be connected to the fixed-focus lens 102, and the cutter A may be distributed on the side of the coaxial light source 103 away from the fixed-focus lens 102.

[0056] For example, the first adjustment component 200 may include: a first angle adjustment mechanism 201, a first position adjustment mechanism 202, a second angle adjustment mechanism 203, and a second position adjustment mechanism 204. The rotating end of the first angle adjustment mechanism 201 may be connected to the side of the line scan camera 101, and the first angle adjustment mechanism 201 may be used to drive the line scan camera 101 to rotate about the central axis L3 of the rotating end of the first angle adjustment mechanism 201. For example, the first position adjustment mechanism 202 and the second position adjustment mechanism 204 may be connected to a first adapter 900.

[0057] The driving end of the first position adjustment mechanism 202 can be connected to the bottom of the first angle adjustment mechanism 201, and the first position adjustment mechanism 202 can be used to drive the first angle adjustment mechanism 201 to rotate around the central axis L4 of the driving end of the first position adjustment mechanism 202, and to drive the first angle adjustment mechanism 201 to move along a third direction f3. The central axis L4 of the driving end of the first position adjustment mechanism 202 can be perpendicular to the central axis L3 of the rotating end of the first angle adjustment mechanism 201, and the central axis L3 of the rotating end of the first angle adjustment mechanism 201 can be perpendicular to both the first direction f1 and the second direction f2.

[0058] The rotating end of the second angle adjustment mechanism 203 can be connected to the coaxial light source 103, and the second angle adjustment mechanism 203 can be used to drive the coaxial light source 103 to rotate around the central axis L5 of the rotating end of the second angle adjustment mechanism 203. A second position adjustment mechanism 204 can be distributed between the second angle adjustment mechanism 203 and the first position adjustment mechanism 202. The driving end of the second position adjustment mechanism 204 can be connected to the bottom of the second angle adjustment mechanism 203, and the second position adjustment mechanism 204 can be used to drive the second angle adjustment mechanism 203 to rotate around the central axis L6 of the driving end of the second position adjustment mechanism 204, and to drive the second angle adjustment mechanism 203 to move along the second direction f2. Here, the central axis L6 of the driving end of the second position adjustment mechanism 204 can be perpendicular to the central axis L5 of the rotating end of the second angle adjustment mechanism 203, and the central axis L5 of the rotating end of the second angle adjustment mechanism can be perpendicular to both the first direction f1 and the second direction f2.

[0059] In this application, as Figure 3 and Figure 4 As shown, the target angle adjustment mechanism may include: a rotary adjustment base B1, a rotary platform B2 mounted on the rotary adjustment base B1, and a turntable knob adjustment component B3 mounted on the rotary adjustment base B1 for driving the rotary platform B2 to rotate. The target angle adjustment mechanism can be either the first angle adjustment mechanism 201 or the second angle adjustment mechanism 203.

[0060] For example, the operator can adjust the rotation direction of the rotating platform B2 by turning the turntable knob adjustment component B3 in different rotation directions, and adjust the rotation angle of the rotating platform B2 by turning the turntable knob adjustment component B3. It should be noted that the rotating platform B2 can be the rotating end of the target angle adjustment mechanism.

[0061] In the embodiments of this application, such as Figure 3 and Figure 4As shown, the target position adjustment mechanism may include an angle adjustment component C1 and a displacement adjustment component C2. The rotating end of the angle adjustment component C1 can be connected to the bottom of the rotary adjustment fixing seat B1 in the target angle adjustment mechanism, and the sliding end of the displacement adjustment component C2 can be connected to the bottom of the angle adjustment component C1. The displacement adjustment component C2 can drive the angle adjustment component C1 to translate along a third direction f3, which is perpendicular to both the first direction f1 and the second direction f2. The target position adjustment mechanism can be either the first position adjustment mechanism 202 or the second position adjustment mechanism 204. Specifically, when the target position adjustment mechanism is the first position adjustment mechanism 202, the rotating end of the angle adjustment component C1 in the target position adjustment mechanism can be connected to the bottom of the rotary adjustment fixing seat B1 in the first angle adjustment mechanism 201; when the target position adjustment mechanism is the second position adjustment mechanism 204, the rotating end of the angle adjustment component C1 in the target position adjustment mechanism can be connected to the bottom of the rotary adjustment fixing seat B1 in the second angle adjustment mechanism 203.

[0062] For example, such as Figure 3 and Figure 4 As shown, the displacement adjustment assembly C2 may include: a displacement adjustment base C21, a movable slide C22 mounted on the displacement adjustment base C21, and a fine-tuning knob C23 mounted on the displacement adjustment base C21 for driving the movable slide C22 to slide along a third direction f3. The bottom of the angle adjustment assembly C1 may be fixed to the movable slide C22.

[0063] The structure of the angle adjustment component C1 can be referenced from the structure and operating principle of the target angle adjustment mechanism described above, and will not be repeated here.

[0064] Optional, please refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of a collet provided in an embodiment of this application. Figure 6 yes Figure 5The diagram shows a cross-sectional view of the collet. The end of the collet 700 may have: a plurality of clamping arms 701 distributed around the central axis of the collet 700, and mounting holes 702 and through holes 703 distributed among the plurality of clamping arms 701 and arranged along the central axis of the collet 700, wherein the inner diameter of the mounting hole 702 may be larger than the inner diameter of the through hole 703. A limiting step surface T is formed in the area of ​​the bottom surface of the mounting hole 702 surrounding the opening of the through hole 703, and the opening k1 of the mounting hole 702 on the side opposite to the through hole 703 is used for insertion of a tool A. In this case, by providing interconnected mounting holes 702 and through holes 703 among multiple clamping arms 701 in the collet 700, the inner diameter of the mounting hole 702 is larger than the inner diameter of the through hole 703. Thus, a limiting step surface T can be formed in the area surrounding the opening of the through hole 703 on the bottom surface of the mounting hole 702. This limiting step surface T can cooperate with the bottom of the tool A during the installation process to ensure the accuracy and stability of the tool A installation.

[0065] In the embodiments of this application, such as Figure 5 and Figure 6 As shown, the mounting hole 702 in the collet 700 may include a mutually communicating limiting insertion hole 7021 and a tool insertion hole 7022, wherein the limiting insertion hole 7021 may be distributed between the through hole 703 and the tool insertion hole 7022. The inner diameter of the tool insertion hole 7022 gradually increases in the direction away from the limiting insertion hole 7021. That is, the tool insertion hole 7022 may be a tapered hole. In this case, by providing the tool insertion hole 7022 within the collet 700, the large opening k1 of the tool insertion hole 7022 allows the tool A to be easily placed into the mounting hole 702 by either an assisted robot or manually.

[0066] Optional, please refer to Figure 3 and Figure 7 , Figure 7 This is a partial structural schematic diagram of another tool vision inspection device provided in this application embodiment. The first angle adjuster 400 may include: a first rotation adjustment fixing base 401, a first rotation platform 402 mounted on the first rotation adjustment fixing base 401, and a first turntable knob adjustment member 403 mounted on the first rotation adjustment fixing base 401 for driving the first rotation platform 402 to rotate. The first rotation platform 402 is connected to the area array camera assembly 300, and the first rotation adjustment fixing base 401 can be fixed to the second position adjuster 500. For example, when the area array camera assembly 300 needs to rotate at a certain angle, the first rotation platform 402 is rotated around its central axis by manipulating the first turntable knob adjustment member 403, thereby driving the area array camera assembly 300 to rotate. It should be noted that the first rotation platform 402 can be the rotating end of the first angle adjuster 400.

[0067] In this embodiment, the second position adjuster 500 may include a first angle adjustment component 501 and a first displacement adjustment component 502. The rotating end of the first angle adjustment component 501 may be connected to the bottom of the first rotation adjustment fixing base 401, and the sliding end of the first displacement adjustment component 502 may be connected to the bottom of the first angle adjustment component 501. The sliding end of the first displacement adjustment component 502 can be used to drive the first angle adjustment component 501 to move along a second direction f2. For example, when the rotating end of the first angle adjustment component 501 is connected to the bottom of the first rotation adjustment fixing base 401, the first angle adjustment component 501 can drive the first angle adjuster 400 and the area scan camera assembly 300 to rotate simultaneously around the central axis of the first angle adjustment component 501; while the sliding end of the first displacement adjustment component 502 is connected to the bottom of the first angle adjustment component 501, the first displacement adjustment component 502 can drive the first angle adjustment component 501, the first angle adjuster 400, and the area scan camera assembly 300 to move simultaneously along the second direction f2. Here, the first angle adjustment component 501 is connected to the first rotation adjustment fixing seat 401, and the first displacement adjustment component 502 can be connected to the second adapter 1100.

[0068] For example, the first displacement adjustment assembly 502 may include: a first displacement adjustment fixed base 502a, a first movable slide 502b mounted on the first displacement adjustment fixed base 502a, and a first fine-tuning knob adjustment member (not shown in the figure) mounted on the first displacement adjustment fixed base 502a for driving the first movable slide 502b to slide along the second direction f2. The bottom of the first angle adjustment assembly 501 may be fixed to the first movable slide 502b. In this way, the rotation of the first fine-tuning knob adjustment member drives the first movable slide 502b to move relative to the first displacement adjustment fixed base 502a along the second direction f2.

[0069] It should be noted that the structure of the first angle adjustment component 501 can refer to the structure and operating principle of the first angle adjuster 400 mentioned above, and will not be repeated here.

[0070] Optional, such as Figure 3 As shown, the tool visual inspection equipment may further include a lifting support frame 1200 arranged along a first direction, one end of which can be connected to the lens barrel in the area array camera assembly 300. In this case, by providing the lifting support frame 1200 in the tool visual inspection equipment, the lifting support frame 1200 can effectively support the lens barrel in the area array camera assembly 300, ensuring the installation stability of the area array camera assembly 300, and thus ensuring the accuracy of the tool tip inspection.
