[0065] like Figure 1-7 As shown, this application provides a workpiece color detection system, including a workpiece positioning device 1, a color detection device, a control device, and a first driving device;

[0066] The control device is used to control the drive device to output a first driving force;

[0067] The driving device is connected to the workpiece positioning device 1, the workpiece grouping device 12 and the color detection device respectively.

[0068] The workpiece positioning device 1 is used to limit and fix the workpiece to be inspected;

[0069] The first driving device is used to drive the workpiece positioning device 1 to move the workpiece to be tested on the workpiece positioning device 1 to a preset detection position according to the first driving force; wherein, the movement of the workpiece to be tested to the preset detection position can indicate that the detection position on the workpiece to be tested is located at the preset detection position.

[0070] In some exemplary embodiments, the first driving device is used to drive the workpiece positioning device 1 to rotate according to the first driving force until the workpiece to be tested on the workpiece positioning device 1 rotates to a preset angle; wherein, the workpiece to be tested rotating to the preset angle can characterize the angle between the detection position of the workpiece to be tested and the preset detection position as the preset angle, wherein the preset angle can be 0 degrees. The first driving device is further used to drive the workpiece positioning device 1 to move the workpiece to be tested, which has rotated to the preset angle, to a preset detection position according to the first driving force.

[0071] In one example, a sliding platform 7 is also included, and the workpiece positioning device 1 is slidably connected to the sliding platform 7;

[0072] The first driving device is used to drive the workpiece positioning device 1 to slide on the sliding platform 7 until the workpiece to be tested slides to the preset testing position.

[0073] The first driving device is further configured to drive the color detection device to a preset detection position, and the control device is configured to control the color detection device to detect the color and gloss of the workpiece to be detected at the preset detection position. The preset detection position corresponds to the preset detection position, and the color detection device located at the preset detection position can detect the workpiece to be detected located at the preset detection position.

[0074] In some exemplary embodiments, a gantry frame 8 is also included; the gantry frame 8 is fixedly mounted on the sliding platform 7; the workpiece positioning device 1 can pass through the gantry frame 8 during the sliding process on the sliding platform 7; the color detection device is mounted on the gantry frame 8 and is slidably connected to the gantry frame 8.

[0075] The first driving device is used to drive the color detection device to slide on the gantry 8 until it moves to the preset detection position. This application can realize automated feeding of the workpiece to be inspected and adjustment of the position of the inspection position, thereby flexibly adjusting the detection position of the workpiece to be inspected. Automated feeding and adjustment of the position of the inspection position can effectively improve detection efficiency, improve the positional accuracy of the workpiece, and thus improve the detection accuracy when inspecting the workpiece.

[0076] In some exemplary embodiments, the first driving device includes a first driving mechanism 4, a second driving mechanism 5, and a third driving mechanism 6;

[0077] The control device is communicatively connected to the first drive mechanism 4, the second drive mechanism 5, and the third drive mechanism 6, respectively.

[0078] The first driving mechanism 4 and the second driving mechanism 5 are respectively drivenly connected to the workpiece positioning device 1;

[0079] The control device is used to control the first drive mechanism 4 to output rotational driving force;

[0080] The first driving mechanism 4 is used to drive the workpiece positioning device 1 to rotate according to the rotation driving force until the workpiece to be detected on the workpiece positioning device 1 rotates to a preset angle.

[0081] The control device is also used to control the second drive mechanism 5 to output sliding drive force;

[0082] The second driving mechanism 5 is used to drive the workpiece positioning device 1 to slide the workpiece to be tested to the preset testing position according to the sliding driving force;

[0083] In some exemplary embodiments, the workpiece positioning device 1 includes a support plate 101 and at least one positioning fixture 102 disposed on the support plate 101;

[0084] The second driving mechanism 5 is drivingly connected to the support plate 101 and is used to drive the support plate 101 to move the positioning fixture 102.

[0085] In one example, the support plate 101 is slidably connected to the sliding platform 7; the second drive mechanism 5 drives the support plate 101 to slide along the sliding platform 7, thereby driving the positioning fixture to move.

[0086] The first driving mechanism 4 is used to drive the positioning fixture 102 to clamp or release the workpiece to be tested;

[0087] The first driving mechanism 4 is also used to drive the positioning fixture 102 to rotate around the support plate 101 until the positioning fixture 102 drives the workpiece to be tested to rotate to a preset angle.

[0088] The third driving mechanism 6 is driven by the color detection device.

[0089] The third driving mechanism 6 is used to drive the color detection device to slide along the gantry to the preset detection position.

[0090] In some exemplary embodiments, the first driving mechanism 4 includes a first driving member 401 and a second driving member; the first driving member 401 and the second driving member are respectively driven connected to the positioning fixture 102.

[0091] The second driving member is used to drive the positioning fixture 102 to clamp or release the workpiece to be tested;

[0092] In some exemplary embodiments, the positioning fixture 102 includes a base 1021 and a gripper assembly 1022 and a positioning assembly 1025 disposed on the base 1021;

[0093] The second driving member is drivingly connected to the gripper assembly 1022;

[0094] The second driving member is used to drive the gripper assembly 1022 to move, so that the gripper assembly 1022 and the positioning assembly 1025 can clamp or release the workpiece to be inspected.

[0095] In this embodiment, the workpiece to be tested can be a ring-shaped structure, and the specific workpiece to be tested can be sleeved on the outer side of the gripper assembly 1022 and the positioning assembly 1025.

[0096] In one example, when the second drive member drives the gripper assembly 1022 in the deployed state, the gripper assembly 1022 and the positioning assembly 1025 can work together to clamp the workpiece to be inspected.

[0097] When the second drive unit drives the gripper assembly 1022 in the retracted state, the workpiece to be inspected can be released.

[0098] The first driving member 401 is used to drive the positioning fixture 102 to rotate, and the workpiece to be tested rotates synchronously with the positioning fixture 102 so that the workpiece to be tested can rotate to different angles.

[0099] In one example, the positioning fixture 102 can rotate about a drive shaft connected to the first drive member 401. Through the cooperation of the positioning fixture 102 and the drive mechanism, this application enables the positioning fixture 102 not only to position the workpiece to be inspected, but also to drive the workpiece to rotate, thereby adjusting the angle of the workpiece to be inspected, and achieving processing such as inspection of the workpiece at different angles.

[0100] In some exemplary embodiments, such as Figure 3 and 4 As shown, the gripper assembly 1022 includes a first gripper 1023 and a second gripper 1024, and the positioning assembly 1025 includes a first positioning block 1026 and a second positioning block 1027.

[0101] The first gripper 1023, the second gripper 1024, the first positioning block 1026, and the second positioning block 1027 are all disposed on the same side of the base 1021; the first gripper 1023 and the first positioning block 1026 are disposed opposite to each other, and the second gripper 1024 and the second positioning block 1027 are disposed opposite to each other; this arrangement can achieve support around the workpiece to be inspected.

[0102] One end of the first gripper 1023 is driven to be connected to the second driving member, and the other end cooperates with the second gripper 1024; the end of the second gripper 1024 away from and close to the second positioning block 1027 is fixedly connected to the base 1021 through the second driving member.

[0103] Specifically, the ends of the first jaw 1023 and the second jaw 1024 that cooperate with each other can slide together through the wedge-shaped surface.

[0104] In one example, the second driving member includes a linear driving member 402 and an elastic driving member; one end of the first gripper 1023 is drivenly connected to the linear driving member 402, and the other end cooperates with the second gripper 1024; one end of the second gripper 1024 near the second positioning block 1027 is fixedly connected to the base 1021 through the elastic driving member.

[0105] The linear drive component 402 can be a drive cylinder, and the elastic drive component can be an elastic element, such as a spring. Correspondingly, when the first gripper 1023 and the second gripper 1024 are in the retracted state, the elastic element can be in the compressed state.

[0106] The second driving member is used to drive the second gripper 1024 to move away from the second positioning block 1027, and the second gripper 1024 drives the first gripper 1023 to move away from the first positioning block 1026 to clamp the workpiece to be tested.

[0107] In one example, the elastic drive member is used to drive the second gripper 1024 to move away from the second positioning block 1027, and the second gripper 1024 drives the first gripper 1023 to move away from the first positioning block 1026 to clamp the workpiece to be tested.

[0108] Specifically, the pressure applied to the elastic drive member can cause the second gripper 1024 to spring away from the second positioning block 1027.

[0109] The second driving member is also used to drive the first gripper 1023 to move toward the first positioning block 1026, and the first gripper 1023 drives the second gripper 1024 to move toward the second positioning block 1027 to release the workpiece to be tested.

[0110] In one example, the linear drive 402 drives the first gripper 1023 to move toward the first positioning block 1026, and the first gripper 1023 drives the second gripper 1024 to move toward the second positioning block 1027 to release the workpiece to be inspected.

[0111] Specifically, the linear drive 402 can push the first gripper 1023 and the second gripper 1024 back to the retracted state, while the elastic drive is in a compressed state.

[0112] In some exemplary embodiments, the base 1021 is provided with a gripper receiving groove 1028, and the first gripper 1023 and the second gripper 1024 are both disposed in the gripper receiving groove 1028. This arrangement allows the first gripper 1023 and the second gripper 1024 to move within the gripper receiving groove 1028, thereby limiting the movement of the first gripper 1023 and the second gripper 1024 and preventing the first gripper 1023 and the second gripper 1024 from moving beyond the limit.

[0113] The upper surfaces of both the first gripper 1023 and the second gripper 1024 protrude from the upper surface of the base 1021. This allows the first gripper 1023 and the second gripper 1024 to limit the position of the workpiece to be inspected.

[0114] In one example, the elastic drive is located in the gripper receiving groove 1028 (not shown in the figure), one end of the elastic drive is fixedly connected to the inner sidewall of the gripper receiving groove, and the other end is fixedly connected to the second gripper 1024.

[0115] In some exemplary embodiments, such as Figure 2 As shown, it also includes a limiting member 1029, which covers the gripper assembly 1022 and is connected to the upper surface of the base 1021.

[0116] The limiting member 1029 is used to limit the gripper assembly 1022; to prevent the first gripper 1023 and the second gripper 1024 from tilting towards the limiting member 1029 during movement, thereby affecting the unfolding and retraction of the first gripper 1023 and the second gripper 1024.

[0117] In one example, the limiting member 1029 can be a limiting block, and the limiting member 1029 is detachably connected to the base 1021.

[0118] In some exemplary embodiments, a coupling 104 is also included; one end of the coupling 104 is connected to the first drive member 401, and the other end is connected to the positioning fixture 102;

[0119] The first driving member 401 drives the positioning fixture 102 to rotate through the coupling 104.

[0120] In one example, a support frame 105 is also included, within which the first drive member 401 is disposed. The coupling 104 is rotatably connected to the positioning fixture 102 via the support frame 105. The support frame 105 provided in this application serves to support the coupling.

[0121] Specifically, the support frame 105 is equipped with bearings, and the coupling is rotatably connected to the positioning fixture 102 through the bearings; thereby avoiding problems such as excessive rotation of the positioning fixture and improving the service life of the positioning fixture.

[0122] In some exemplary embodiments, an optical fiber sensor 103 is also included, which is communicatively connected to the control device; the optical fiber sensor 103 is used to detect the state of the workpiece to be detected on the positioning fixture 102.

[0123] Specifically, the working principle of the workpiece positioning device is as follows:

[0124] The workpiece to be inspected is placed on the outer surface of the positioning component 1025 and the gripper component 1022 of the positioning fixture 102. The linear drive 402 is controlled to cancel the pushing force on the first gripper 1023. At the same time, the elastic drive, based on its own elastic force, pushes the second gripper 1024 to move away from the second positioning block 1027. Then, the second gripper 1024 drives the first gripper 1023 to move away from the first positioning block 1026 until the workpiece to be inspected is tightened, thus limiting the workpiece to be inspected. When it is necessary to release the workpiece to be inspected, the linear drive 402 is controlled to push the first gripper 1023 to move closer to the first positioning block 1026. Then, the first gripper 1023 drives the second gripper 1024 to move closer to the second positioning block 1027 until the reaction force of the elastic drive is equal to the force of the linear drive 402. At this time, the workpiece to be inspected can be released.

[0125] In some exemplary embodiments, the color detection device includes a color detection component 2 and a gloss detection component 3; the color detection component 2 and the gloss detection component 3 are respectively communicatively connected to the control device;

[0126] Specifically, the color detection component 2 and the gloss detection component 3 can be arranged side by side on the gantry 8;

[0127] In one example, two gantry frames 8 can be set side by side, with the color detection component 2 and the gloss detection component 3 set on different gantry frames 8 respectively; both the color detection component 2 and the gloss detection component 3 can slide along the gantry frame 8.

[0128] In one example, the color detection component 2 and the gloss detection component 3 can also move toward or away from the sliding platform 7 in a direction perpendicular to the sliding direction of the gantry 8.

[0129] The preset detection positions include a first preset detection position and a second preset detection position;

[0130] In one example, the preset detection position may include a first preset detection position and a second preset detection position; wherein the first preset detection position corresponds to a first preset detection position; and the second preset detection position corresponds to a second preset detection position.

[0131] The third driving mechanism 6 can move the color detection component 2 to the first preset detection position and drive the gloss detection component 3 to the second preset detection position.

[0132] The control device is used to control the color detection component 2 to detect the color of the workpiece to be detected at the first preset detection position;

[0133] The control device is also used to control the gloss detection component 3 to detect the gloss of the workpiece to be tested at the second preset detection position.

[0134] In this embodiment, different detection positions on the workpiece can be achieved by adjusting the position of the workpiece to be inspected, as well as the positions of the color detection component 2 and the gloss detection component 3, thereby improving detection efficiency.

[0135] In some exemplary embodiments, it also includes a material feeding hopper 9, a feeding assembly 10, and a pressure plate assembly 11;

[0136] In one example, such as Figure 5 As shown, the material supply hopper 9 can be an upper and lower circulating hopper to continuously supply the workpiece to be tested.

[0137] The feeding assembly 10 and the pressure plate assembly 11 are respectively driven by the driving device;

[0138] The driving device is used to drive the feeding assembly 10 to grab the workpiece to be inspected from the feeding hopper 9 according to the first driving force, and place the workpiece to be inspected on the workpiece positioning device 1;

[0139] In one example, such as Figure 6 As shown, the feeding assembly may include a first clamping assembly 1001 and a first clamping drive 1002; the first clamping drive 1002 is driven to the first clamping assembly 1001, and the first clamping drive 1002 can drive the first clamping assembly 1001 to clamp or release the workpiece to be tested.
