[0074] See also Figure 1 to Figure 2 In some embodiments of the present application, a detection device 100 proposed in the present application includes: a carrier assembly 70, a first conveying mechanism 10, a detection mechanism 50 and a handling mechanism 60.

[0075] The tray assembly 70 is used to load the workpiece 80 to be tested. The first conveying mechanism 10 is used to convey the tray assembly 70. The detection mechanism 50 is used to detect the workpiece 80 to be tested. The transport mechanism 60 is used to transport the workpiece 80 to be tested between the first conveying mechanism 10 and the detection mechanism 50.

[0076] During the process of testing the workpiece 80, the workpiece 80 is loaded through the loading plate assembly 70, thereby reducing the risk of damage to the workpiece 80 and facilitating the fixing and positioning of the workpiece 80. Multiple workpieces 80 can be loaded through the loading plate assembly 70, so that the testing device 100 can continuously test multiple workpieces 80, thereby ensuring the continuity of the working process of the testing device 100 and improving the working efficiency of the testing device 100.

[0077] The first conveying mechanism 10 conveys the tray assembly 70 loaded with the workpiece 80 to be tested, so that the workpiece 80 to be tested can be circulated in the testing device 100, so that the testing device 100 can complete the detection of various parameters of the workpiece 80 to be tested. Multiple tray assemblies 70 can be conveyed by the first conveying mechanism 10, reducing the risk of the internal structure of the testing device 100 pausing or stopping due to lack of material, further ensuring the continuity of the testing process of the testing device 100, and further improving the working efficiency of the testing device 100.

[0078] After the first conveying mechanism 10 conveys the tray assembly 70 to the working area of ​​the transporting mechanism 60, the transporting mechanism 60 takes out the workpiece 80 to be tested from the tray assembly 70 at the first conveying mechanism 10, and transports the workpiece 80 to the detection mechanism 50, and the detection mechanism 50 detects various indicators of the workpiece 80 to be tested. Among them, the detection indicators of the workpiece 80 to be tested include the horizontal relative distance of the feature points, the vertical relative distance, the hole spacing, the hole depth, the diameter, the fillet, the thickness and other hard indicators of the drawing specifications, as well as the height of the pin, whether the number is missing, the verticality and the position, including the minimum spacing between the pin holes and other dimensions.

[0079] After the inspection mechanism 50 completes the inspection of the workpiece 80, the inspection-completed workpiece is transported to the tray assembly 70 in the first conveying mechanism 10 through the transport mechanism 60. If a defective product is detected, the defective workpiece is removed from the production line.

[0080] It is understandable that when the tray assembly 70 loaded with the workpieces 80 to be tested arrives within the working area of ​​the transport mechanism 60, the transport mechanism 60 takes out the workpieces 80 to be tested from the tray assembly 70. When the transport mechanism 60 takes out a certain number of workpieces 80 to be tested from the tray assembly 70, there will be empty spaces in the tray assembly 70 at least equal to the number of workpieces 80 to be tested that have been taken out. When the detection mechanism 50 completes the detection of the workpieces 80 to be tested, the transport mechanism 60 transports the workpieces that have been tested to the empty spaces in the tray assembly 70. This alternating cycle is repeated until all the workpieces 80 to be tested in the tray assembly 70 are detected by the detection mechanism 50.

[0081] When the inspection mechanism 50 detects defective products, the transport mechanism 60 can put the defective workpieces into the offline assembly line or the defective product placement area to remove the defective workpieces from the offline assembly line.

[0082] A defective product placement area may be provided in the tray assembly 70 , and defective workpieces may be placed in the defective product placement area of ​​the tray assembly 70 , so that the defective workpieces are removed from the production line along with the tray assembly 70 .

[0083] After all the workpieces 80 to be tested in the carrier assembly 70 are tested by the testing mechanism 50, if there are vacancies in the carrier assembly 70 due to unqualified workpieces being taken offline, the carrier assembly 70 with the vacancies can be directly transferred to the next workstation or taken offline; the carrier assembly 70 with the vacancies can also be moved to a waiting position, and the carrier assembly 70 can continue to circulate after all the vacancies in the carrier assembly 70 are loaded with tested workpieces.

[0084] In some embodiments of the present application, the carrier assembly 70 is provided with at least two workpieces 80 to be tested, the detection mechanism 50 includes at least one detection device 51, the detection device 51 includes a fixture assembly 511 and a detection assembly 513, the fixture assembly 511 is used to fix the workpiece 80 to be tested, and the detection assembly 513 is used to detect the workpiece 80 to be tested. Wherein, let the discharge time of the detection mechanism 50 be T, and the duration of one working cycle of the conveying mechanism 60 be S, then T≤S. The discharge time of the detection mechanism 50 is configured as the time period from when the conveying mechanism 60 completes the discharge of the material in the detection mechanism 50 to when the workpiece 80 to be tested in the detection mechanism 50 is completely detected. The working cycle content of the conveying mechanism 60 includes picking up and discharging materials in the detection mechanism 50, discharging and picking up materials at the first conveying mechanism 10, and arriving at the detection mechanism 50.

[0085] During the process of testing the workpiece 80 to be tested, a plurality of workpieces 80 to be tested are loaded by the tray assembly 70, and the tray assembly 70 is moved along the conveying direction of the first conveying mechanism 10 by the first conveying mechanism 10. After the tray assembly 70 moves to the material taking range of the conveying mechanism 60, the untested workpieces 80 to be tested are conveyed to the testing mechanism 50 by the conveying mechanism 60, and the tested workpieces 80 are moved out of the testing mechanism 50. By making the material discharging time of the testing mechanism 50 greater than or equal to the time of one working cycle of the conveying mechanism 60, when the conveying mechanism 60 reaches the testing mechanism 50 after taking the material at the first conveying mechanism 10, there are tested workpieces 80 waiting to be discharged at the testing mechanism 50, and after the conveying mechanism 60 reaches the testing mechanism 50, the material discharging and placing of the workpieces 80 to be tested can be performed at the testing mechanism 50, thereby avoiding the waiting situation of the conveying mechanism 60 and improving the production efficiency of the testing equipment 100.

[0086] When the material discharging time of the detection mechanism 50 is equal to the time of one working cycle of the conveying mechanism 60, when the conveying mechanism 60 takes the material from the first conveying mechanism 10 and reaches the detection mechanism 50, the workpiece 80 to be detected is just detected at the detection mechanism 50, so that the production rhythm of the detection mechanism 50 is consistent with the production rhythm of the conveying mechanism 60, avoiding the situation where the detection mechanism 50 and the conveying mechanism 60 are waiting, so that the internal mechanism of the detection equipment 100 can operate efficiently and continuously. In this way, the production efficiency of the detection equipment 100 is improved.

[0087] In the initial state of the detection device 100, the first conveying mechanism 10 conveys the tray assembly 70 loaded with the workpiece 80 to be detected to the working area of ​​the transport mechanism 60. The transport mechanism 60 arrives at the first conveying mechanism 10 and takes out the workpiece 80 from the tray assembly 70, and then transports the workpiece 80 to one of the detection devices 51 in the detection mechanism 50, and fixes the workpiece 80 to be detected by the fixture assembly 511. After the fixture assembly 511 fixes the workpiece 80 to be detected, the fixture assembly 511 and the detection assembly 513 perform a series of actions, so that the detection assembly 513 completes the detection of the workpiece 80 to be detected. After the transport mechanism 60 is at one of the detection devices 51 in the detection mechanism 50, it moves to the first conveying mechanism 10 again, and takes the workpiece 80 to be detected at the tray assembly 70. At this time, the detection device 51 loaded with the workpiece 80 to be detected continues to detect the workpiece 80 to be detected. After the transport mechanism 60 has taken all the materials from the tray assembly 70, it transports the workpiece 80 to be tested to another idle testing device 51. This cycle continues until all idle testing devices 51 are loaded with the workpiece 80 to be tested and the workpiece 80 to be tested is tested.

[0088] During the process of the conveying mechanism 60 conveying the workpiece 80 to be measured in the carrier assembly 70 to the detection mechanism 50, if a detection device 51 in the detection mechanism 50 completes the detection of the workpiece 80 to be measured, the detection device 51 that has completed the detection work can be loaded and unloaded first, so that the detection device 51 that has completed the detection work can work continuously, thereby improving the working efficiency of the detection equipment 100; or after all the detection devices 51 are equipped with the workpiece 80 to be measured, the detection device 51 that has completed the detection work can be loaded and unloaded, thereby reducing the waiting time of the empty detection device 51 and improving the working efficiency of the detection equipment 100.

[0089] In some embodiments of the present application, the number of detection devices 51 in the detection mechanism 50 is configured according to the working speed of the conveying mechanism 60, so that when a detection device 51 that has completed the detection appears in the detection mechanism 50, the conveying mechanism 60 completes the loading of all detection devices 51.

[0090] In this way, when a detection device 51 that has completed the detection appears in the detection mechanism 50, the conveying mechanism 60 completes the loading of all the detection devices 51, so that when the conveying mechanism 60 loads and unloads the detection device 51 that has completed the detection work, there will be no empty detection devices 51 waiting, thereby improving the overall efficiency of the detection mechanism 50.

[0091] When all the detection devices 51 in the detection mechanism 50 start working, if a detection device 51 that has completed detection appears in the detection mechanism 50, the conveying mechanism 60 carrying the workpiece 80 to be detected arrives at the detection device 51 that has completed detection, and then loads and unloads the workpiece 80 to be detected at the detection device 51 that has completed detection (that is, the workpiece that has completed detection is taken out from the detection device 51, and the workpiece 80 to be detected is placed in the detection device 51 that has completed detection).

[0092] After the transport mechanism 60 completes loading and unloading of the workpiece 80 to be tested at the detection device 51 to be tested, the workpiece that has completed the test is transported to the carrier assembly 70 of the first conveying mechanism 10, and the workpiece 80 to be tested is taken out of the carrier assembly 70, and the transport mechanism 60 then moves to the target detection device 51 (wherein the target detection device 51 is the detection device 51 that is about to complete the detection). When the transport mechanism 60 carrying the workpiece 80 to be tested moves to the target detection device 51, the target detection device 51 has just completed the detection work, and the transport mechanism 60 can load and unload the workpiece 80 to be tested at the target detection device 51. In this way, the situation where the detection device 51 and the transport mechanism 60 are waiting is avoided, and it is ensured that the transport mechanism 60 and all detection devices 51 can operate continuously and efficiently, thereby improving the working efficiency of the detection equipment 100.

[0093] In some embodiments of the present application, let: the duration of one working cycle of the transport mechanism 60 be S, the number of detection devices 51 be n, and the detection duration of the detection device 51 be t, then t=nS. The working cycle of the transport mechanism 60 includes picking up and placing materials at the detection device 51 that has completed the detection, placing and placing materials at the first conveying mechanism 10, and reaching the target detection mechanism 50.

[0094] The detection duration of the detection device 51 is configured as an integral multiple of the duration of one working cycle of the conveying mechanism 60, and the number of the detection devices 51 is configured as a multiple of the detection duration of the detection device 51 relative to the duration of one working cycle of the conveying mechanism 60. Thus, when the conveying mechanism 60 is full of all the detection devices 51 and reaches the target detection mechanism 50, the target detection mechanism 50 just completes the detection of the workpiece 80 to be detected, thereby ensuring that the conveying mechanism 60 and all the detection devices 51 can operate continuously and efficiently, thereby improving the working efficiency of the detection device 100.

[0095] See also Figure 1 to Figure 2 and Figure 7 In some embodiments of the present application, the detection mechanism 50 includes at least two detection devices 51, and the conveying mechanism 60 takes and discharges materials from one of the detection devices 51 while the other detection devices 51 perform detection work.

[0096] When the transport mechanism 60 takes or places material in one of the detection devices 51 , the other detection devices 51 perform detection work synchronously. In this way, the action of the transport mechanism 60 overlaps with the action of the detection device 51 , thereby improving the continuity of the actions of the detection device 51 and the transport mechanism 60 , reducing the waiting time of the detection device 51 and the transport mechanism 60 , and improving the working efficiency of the detection equipment 100 .

[0097] See also Figure 1 to Figure 2 and Figures 7 and 8 In some embodiments of the present application, a testing device 100 provided by the present application includes: a carrier assembly 70, a first conveying mechanism 10, a testing assembly 513, a fixture assembly 511 and a transport mechanism 60. The carrier assembly 70 is provided with at least two workpieces 80 to be tested.

[0098] The first conveying mechanism 10 is used to convey the carrier assembly 70. The detection assembly 513 is used to detect the workpiece 80 to be detected. The fixture assembly 511 includes at least one fixing assembly 5111, and the fixing assembly 5111 is used to fix the workpiece 80 to be detected when the detection assembly 513 detects the workpiece 80 to be detected. The transport mechanism 60 is used to transport the workpiece 80 to be detected between the first conveying mechanism 10 and the fixture assembly 511, and the transport mechanism 60 includes at least two material picking assemblies 61, and the material picking assemblies 61 are used to pick up the workpiece 80 to be detected. Among them, the number of the material picking assemblies 61 is greater than the number of the fixing assemblies 5111.

[0099] During the inspection of the workpieces 80 , the plurality of workpieces 80 are loaded by the tray assembly 70 , and the tray assembly 70 is transported by the first conveying mechanism 10 , so that the plurality of workpieces 80 are moved along the conveying direction of the first conveying mechanism 10 .

[0100] When the carrier assembly 70 moves to the working area of ​​the transport mechanism 60, the transport mechanism 60 transports the untested workpiece 80 to the fixture assembly 511, and moves the tested workpiece 80 out of the fixture assembly 511, so that the detection assembly 513 can continue to perform detection work.

[0101] The number of the material-picking components 61 in the transport mechanism 60 is made greater than the number of the fixed components 5111 in the fixture component 511. In the process of the transport mechanism 60 picking up and placing materials at the fixture component 511, the transport mechanism 60 carries the workpieces 80 to be tested that are equal to the number of the fixed components 5111 and moves to the fixture component 511. The transport mechanism 60 takes out the workpieces 80 to be tested from the fixture component 511 through the empty material-picking components 61, so that some of the fixed components 5111 in the fixture component 511 are empty. Then, the workpieces 80 to be tested that have not been tested are placed into the empty fixed components 5111, so that some of the material-picking components 61 in the transport mechanism 60 are empty. Then, the workpieces 80 to be tested that have been tested are taken out from the fixture component 511 through the empty material-picking components 61. This cycle is repeated until all the workpieces 80 to be tested that have been tested in the fixture component 511 are taken out, and the loading of the workpieces 80 to be tested that have not been tested is completed.

[0102] By picking up and placing the workpieces 80 to be tested in sequence, the picking component 61 is not restricted by the distance between adjacent workpieces 80 to be tested, thereby improving the picking and placing compatibility of the conveying mechanism 60 in the detection equipment 100.

[0103] In some embodiments of the present application, the transport mechanism 60 alternately picks up and places the workpiece 80 to be measured at the fixture assembly 511 .

[0104] During the process of the conveying mechanism 60 taking and placing materials at the fixture assembly 511, the conveying mechanism 60 carries the workpieces 80 to be tested equal to the number of the fixed assemblies 5111 and moves to the fixture assembly 511. The conveying mechanism 60 takes out the workpieces 80 to be tested from the fixture assembly 511 through the empty material taking assembly 61, so that some of the fixed assemblies 5111 in the fixture assembly 511 are empty. Then, the untested workpieces 80 to be tested are placed into the empty fixed assemblies 5111, so that some of the material taking assemblies 61 in the conveying mechanism 60 are empty. Then, the workpieces 80 to be tested that have been tested are taken out from the fixture assembly 511 through the empty material taking assembly 61. This cycle is repeated until all the workpieces 80 to be tested that have been tested in the fixture assembly 511 are taken out, and the loading of the untested workpieces 80 to be tested is completed. By picking up and placing the workpieces 80 to be tested in sequence, the distance between adjacent material picking components 61 is not limited by the distance between adjacent workpieces 80 to be tested in the fixture component 511, thereby improving the compatibility of the conveying mechanism 60 in the detection equipment 100 for picking up and placing materials.

[0105] Similarly, when the transport mechanism 60 loads and unloads the workpiece 80 at the tray assembly 70, it also alternately picks and places the workpiece 80. The picking and placing process of the transport mechanism 60 at the tray assembly 70 is the same as that at the fixture assembly 511, so it will not be repeated.

[0106] By making the conveying mechanism 60 alternately pick up and place the workpiece 80 to be tested at the carrier assembly 70, the distance between adjacent picking assemblies 61 in the conveying mechanism 60 is not limited by the distance between adjacent workpieces 80 to be tested in the carrier assembly 70, thereby improving the compatibility of the conveying mechanism 60 in the detection equipment 100 for picking up and placing materials.

[0107] See also Figure 1 to Figure 2 and Fig. 9 In some embodiments of the present application, the number of material-taking components 61 is one more than the number of fixing components 5111 .

[0108] Since the number of the material picking components 61 is one more than the number of the fixed components 5111, during the process of the conveying mechanism 60 picking up and placing materials at the fixture component 511, the conveying mechanism 60 carries the workpieces 80 to be tested equal to the number of the fixed components 5111 and moves to the fixture component 511. At this time, there is an empty position of the material picking component 61 in the conveying mechanism 60. The conveying mechanism 60 takes out the workpieces 80 to be tested from the fixture component 511 through the empty material picking component 61, so that one of the fixed components 5111 in the fixture component 511 is empty. The conveying mechanism 60 then puts one of the untested workpieces 80 to be tested into the empty fixed component 5111, so that there is an empty material picking component 61 in the conveying mechanism 60. The conveying mechanism 60 then takes out a workpiece 80 to be tested that has been tested from the fixture component 511 through the empty material picking component 61, so that there is another empty fixed component 5111 in the fixture component 511. The transport mechanism 60 then places one of the untested workpieces 80 into the empty fixture assembly 5111. This cycle is repeated until all the tested workpieces 80 in the fixture assembly 511 are taken out and the untested workpieces 80 are loaded.

[0109] By picking up and placing the workpiece 80 to be tested individually, multiple picking components 61 are prevented from picking up materials at the same time, so that the distance between adjacent picking components 61 is not limited by the distance between adjacent workpieces 80 to be tested in the fixture component 511, thereby improving the compatibility of picking up and placing materials by the conveying mechanism 60 in the detection equipment 100.

[0110] In some embodiments of the present application, the transport mechanism 60 includes a parallel lifting manipulator, which drives all the material picking components 61 to move synchronously.

[0111] The parallel lifting manipulator has high precision, good stability, fast moving speed, small mass and inertia, and a large working range. It can adapt to the handling of the workpiece 80 to be tested and ensure that the testing efficiency of the testing equipment 100 meets the expected requirements.

[0112] See also Figures 9 and 10In some embodiments of the present application, the transport mechanism 60 further includes an extending and retracting assembly 62, and the extending and retracting assembly 62 is used to extend or retract the material taking assembly 61.

[0113] When the transport mechanism 60 is picking up materials, the material picking assembly 61 is extended through the extending and retracting assembly 62, thereby preventing other material picking assemblies 61 carrying the workpiece 80 to be measured from interfering with the structure at the target position. After the material picking assembly 61 has finished picking up the workpiece 80 to be measured, the extending and retracting assembly 62 retracts the material picking assembly 61, thereby preventing the material picking assembly 61 that has finished picking up materials from interfering with the material picking assembly 61 that is picking up materials. Similarly, when the transport mechanism 60 is releasing materials, the extending and retracting assembly 62 extends or retracts the material picking assembly 61, thereby preventing interference during the material releasing process and improving the reliability of the transport mechanism 60.

[0114] In some embodiments of the present application, the extending and retracting assembly 62 includes a telescopic cylinder.

[0115] When the telescopic cylinder is extended, the material taking assembly 61 is driven to be extended; when the telescopic cylinder is retracted, the material taking assembly 61 is driven to be retracted.

[0116] Each extending and retracting assembly 62 drives one material taking assembly 61 to extend or retract, so that the material taking assemblies 61 at different positions can extend or retract independently without being affected by other material taking assemblies 61 .

[0117] In some embodiments of the present application, the material picking assembly 61 includes a vacuum suction cup assembly 63 .

[0118] When the material picking component 61 is picking up the workpiece 80 to be measured, the workpiece 80 to be measured is sucked up by the vacuum suction cup component 63 , thereby reducing damage to the workpiece 80 to be measured and ensuring the quality and yield rate of the workpiece 80 to be measured.

[0119] In some embodiments of the present application, the detection device 51 further includes a moving component 512 , and the moving component 512 is used to move the clamp component 511 from the detection range of the detection component 513 to the material picking and placing range of the conveying mechanism 60 .

[0120] In some embodiments of the present application, the fixture assembly 511 includes at least one fixing assembly 5111, and the fixing assembly 5111 is used to fix the workpiece to be tested 80. The arrangement range of the fixing assembly 5111 is configured so that the fixing assembly 5111 in the same fixture assembly 511 covers the detection range of the detection device 51, and all the fixing assemblies 5111 can appear in the detection range of the detection assembly 513 at the same time.

[0121] By configuring the arrangement range of the fixing components 5111 so that the fixing components 5111 in the same fixture component 511 fully cover the detection range of the detection device 51, it is avoided that there are empty spaces in the detection area of ​​the detection device 51, and the detection efficiency of the detection device 51 is improved. By making all the fixing components 5111 appear in the detection range of the detection component 513 at the same time, the detection device 51 can detect all the workpieces 80 to be detected in the fixture component 511 at one time, thereby reducing the movement of the detection device 51 and further improving the detection efficiency of the detection device 51.

[0122] See also Figures 7 and 8 In some embodiments of the present application, the detection device 51 further includes a rotating assembly 514 , and the rotating assembly 514 is used to drive the fixture assembly 511 to rotate around a preset direction X. The preset direction X is configured as a direction that is not perpendicular to the detection area of ​​the detection assembly 513 .

[0123] During the process of the detection component 513 detecting the workpiece 80 , the workpiece 80 is positioned and fixed by the fixture component 511 to ensure the reliability and accuracy of the detection result.

[0124] After the detection of one side of the workpiece 80 is completed, the rotating assembly 514 drives the fixture assembly 511 to rotate, so that the workpiece 80 to be detected rotates along the preset direction X within the detection range of the detection assembly 513. Since the preset direction X is not perpendicular to the detection area of ​​the detection assembly 513, the detection assembly 513 can detect multiple angles of the workpiece 80 to be detected, so that the detection assembly 513 can detect multiple detection indicators of the workpiece 80 to be detected, thereby improving the detection capability of the detection assembly 513 and improving the detection efficiency of the detection device 51.

[0125] In some embodiments of the present application, the preset direction X is configured to be parallel to the detection area of ​​the detection component 513 .

[0126] In order to ensure the validity and accuracy of the detection results of the detection component 513, the bearing surface of the clamp component 511 is parallel to the detection area of ​​the detection component 513, so that in the process of the detection component 513 detecting the workpiece 80 to be detected, the surface parallel to the detection area of ​​the detection component 513 can be used as a reference surface to complete the detection of the workpiece 80 to be detected, thereby ensuring the validity and accuracy of the detection results.

[0127] By making the preset direction X parallel to the detection area of ​​the detection component 513, when the detected surface of the workpiece 80 to be detected is rotated to face the detection component 513, the detected surface of the workpiece 80 to be detected is parallel to the detection area of ​​the detection component 513, thereby ensuring the validity and accuracy of the detection result of the detection component 513.

[0128] In some embodiments of the present application, the detection component 513 includes a camera detection sensor, a line scanning laser detection sensor, and a driving mechanism. The camera detection sensor and the line scanning laser detection sensor are both installed on the driving mechanism, and the driving mechanism is used to drive the camera detection sensor and the line scanning laser detection sensor to move, so that the camera detection sensor and the line scanning laser detection sensor complete the detection of the workpiece 80 to be detected.

[0129] In some embodiments of the present application, the driving mechanism includes a translation mechanism and a rotation mechanism.

[0130] The camera detection sensor and the line scanning laser detection sensor are driven to move independently within the space range by the translation mechanism, and are driven to rotate independently by the rotation mechanism. By making the camera detection sensor and the line scanning laser detection sensor move and rotate independently, the camera detection sensor and the line scanning laser detection sensor can independently complete their respective detection tasks, and the camera detection sensor and the line scanning laser detection sensor can detect the workpiece 80 to be detected from different positions and angles, so as to realize full-size detection of the workpiece 80 to be detected.

[0131] In some embodiments of the present application, the fixture assembly 511 is installed with a reflector 5112 , and each fixing assembly 5111 is configured with at least one reflector 5112 . The reflector 5112 is used to reflect the side image of the workpiece 80 to be measured to the detection assembly 513 .

[0132] After the workpiece 80 to be measured is installed on the fixture assembly 511, the upper side of the workpiece 80 to be measured faces the detection assembly 513, so that the detection assembly 513 detects the upper side of the workpiece 80 to be measured. The rotating assembly 514 rotates with the fixture assembly 511, so that the lower side of the workpiece 80 to be measured faces the detection assembly 513, so that the detection assembly 513 detects the lower side of the workpiece 80 to be measured. In the process of the detection assembly 513 detecting the upper side or lower side of the workpiece 80 to be measured, the side image of the workpiece 80 to be measured is reflected to the detection assembly 513 by the reflector 5112, so that the detection assembly 513 can capture the image of the side of the workpiece 80 to be measured, so that the detection assembly 513 detects the upper side or lower side of the workpiece 80 to be measured and the side of the workpiece 80 to be measured, thereby improving the detection efficiency of the detection device 51. It should be pointed out that the side of the workpiece 80 to be measured mentioned here is configured as the side of the workpiece 80 to be measured that is located on the upper side or lower side of the workpiece 80 to be measured.

[0133] See also Figure 8 In some embodiments of the present application, the reflector 5112 includes a reflective prism, and further, the reflector 5112 includes a 45° angle reflective prism.

[0134] A 45° angle reflecting prism is a prism whose reflecting surface forms an angle of 45° with the mounting surface.

[0135] The reflector 5112 is installed on the side of the fixing component 5111 in the fixture component 511 . When the workpiece 80 to be measured is fixed to the fixing component 5111 , the reflector 5112 reflects the side image of the workpiece 80 to the detection component 513 according to the principle of light reflection.

[0136] In some embodiments of the present application, the fixture assembly 511 fixes the workpiece to be measured 80 by vacuum adsorption, and the fixing assembly 5111 is provided with an adsorption hole and a positioning block. The workpiece to be measured 80 is positioned by the positioning block, and a negative pressure device is used to generate negative pressure at the adsorption hole, and then the workpiece to be measured 80 is fixed to the fixing assembly 5111 by vacuum adsorption.

[0137] See also Figures 7 and 8 In some embodiments of the present application, the reflector 5112 is located on one side or both sides of the fixing component 5111 in the preset direction X.

[0138] After the workpiece 80 to be measured is fixed at the fixing component 5111 of the fixture component 511, during the process of the detection component 513 detecting the workpiece 80 to be measured, the fixture component 511 is driven to rotate around the preset direction X through the rotating component 514, so that the upper side, lower side and side perpendicular to the preset direction X of the workpiece 80 to be measured can be detected by the detection component 513.

[0139] However, when the rotating component 514 drives the clamp component 511 to rotate around the preset direction X, the two sides of the fixed component 5111 in the preset direction X cannot always face the detection component 513, thereby causing the workpiece 80 to be unable to be detected by the detection component 513 on both sides in the preset direction X.

[0140] The reflective component 5112 is arranged on one side or both sides of the fixed component 5111 in the preset direction X, so that the side image of the workpiece 80 to be measured in the preset direction X can be reflected by the reflective component 5112 to the detection component 513, so that the detection component 513 can detect the side of the workpiece 80 to be measured in the preset direction X, thereby realizing automatic full-size detection of the workpiece 80 to be measured and improving the detection efficiency.

[0141] See also Figures 1 to 3 In some embodiments of the present application, a detection device 100 provided in the present application includes: a first conveying mechanism 10, a second conveying mechanism 20, a transfer mechanism 40, a detection mechanism 50 and a handling mechanism 60.

[0142] The first conveying mechanism 10 is used to convey the workpiece 80 to be measured. The second conveying mechanism 20 is docked with the first conveying mechanism 10, and the second conveying mechanism 20 is used to convey the workpiece 80 to be measured. The transfer mechanism 40 is used to transport the workpiece 80 to be measured between the first conveying mechanism 10 and the second conveying mechanism 20 during the process of the first conveying mechanism 10 transporting the workpiece 80 to be measured. The detection mechanism 50 is arranged along the conveying direction of the first conveying mechanism 10. The transport mechanism 60 is used to transport the workpiece 80 to be measured between the detection mechanism 50 and the first conveying mechanism 10.

[0143] During the operation of the detection device 100, the workpiece 80 to be detected is transported by the first conveying mechanism 10, and the workpiece 80 to be detected by the first conveying mechanism 10 is transported to the detection mechanism 50 by the transporting mechanism 60, and then the workpiece 80 to be detected is detected by the detection mechanism 50. After the detection of the workpiece 80 to be detected at the detection mechanism 50 is completed, the transporting mechanism 60 transports the workpiece 80 to be detected to the first conveying mechanism 10, and the first conveying mechanism 10 continues to transport the workpiece 80 to be detected.

[0144] When the workpiece 80 being transported by the first conveying mechanism 10 is to be unloaded, the transfer mechanism 40 transports the workpiece 80 in the first conveying mechanism 10 to the second conveying mechanism 20 , and then the second conveying mechanism 20 unloads the workpiece 80 .

[0145] When the first conveying mechanism 10 is loaded with materials midway, the workpiece 80 to be measured can be loaded at the second conveying mechanism 20, and the second conveying mechanism 20 conveys the workpiece 80 to be measured in the direction of the first conveying mechanism 10, and then the workpiece 80 to be measured at the second conveying mechanism 20 is transported to the first conveying mechanism 10 through the transfer mechanism 40.

[0146] The second conveying mechanism 20 is used to temporarily load and unload the workpieces 80 to be tested, so as to perform random inspection and re-inspection of the workpieces 80 to be tested without stopping the machine, and to verify the repeatability accuracy of the testing mechanism 50. In this way, the testing device 100 is guaranteed to operate stably and reliably.

[0147] During the operation of the detection device 100, the workpiece 80 to be detected can be manually loaded and unloaded at the second conveying mechanism 20, thereby facilitating replenishment, random inspection, re-inspection of the workpiece 80 to be detected, and verifying the repeatability of the detection mechanism 50, and enabling the detection device 100 to be produced independently without being affected by its upstream and downstream equipment.

[0148] See also Figure 1In some embodiments of the present application, the second conveying mechanism 20 includes a first conveying device 201 and a second conveying device 202. The first conveying device 201 is arranged upstream of the detection mechanism 50, and the first conveying device 201 is used to load the workpiece 80 to be measured. The second conveying device 202 is arranged downstream of the detection mechanism 50, and the second conveying device 202 is used to unload the workpiece 80 to be measured. The transfer mechanism 40 includes a first transfer device 401 and a second transfer device 402. The first transfer device 401 is used to transport the workpiece 80 to be measured between the first conveying device 201 and the first conveying mechanism 10. The second transfer device 402 is used to transport the workpiece 80 to be measured between the second conveying device 202 and the first conveying mechanism 10.

[0149] During the process of replenishing the workpiece 80 to be measured, the material can be discharged at the first conveying device 201 through external equipment or manually, and the workpiece 80 to be measured can be conveyed toward the first conveying mechanism 10 through the first conveying device 201, and the workpiece 80 to be measured can be transferred to the first conveying mechanism 10 through the first transfer device 401, and then the workpiece 80 to be measured can be conveyed to the transport mechanism 60 through the first conveying mechanism 10, and the workpiece 80 to be measured can be transported to the detection mechanism 50 through the transport mechanism 60, and the workpiece 80 to be measured can be detected by the detection mechanism 50.

[0150] During the random inspection of the workpiece 80 to be tested, after the detection mechanism 50 completes the inspection of the workpiece 80 to be tested, the first conveying mechanism 10 conveys the inspected workpiece 80 to the second transfer device 402, and transfers the inspected workpiece 80 to the second conveying device 202 through the second transfer device 402, and then provides the second conveying device 202 to transport the inspected workpiece 80 to the outside of the detection equipment 100, and then unload the workpiece 80 to be tested through external equipment or manually, and transfer the inspected workpiece 80 to another inspection station for another inspection of the workpiece 80 to determine the reliability and accuracy of the inspection result of the detection equipment 100 on the workpiece 80 to be tested.

[0151] During the re-inspection of the workpieces 80 to be tested, the workpieces 80 to be tested that have been tested are loaded from the first conveying device 201, and then the workpieces 80 to be tested are tested again by the testing mechanism 50, so as to determine the accuracy of the test results and improve the reliability of the testing mechanism 50. The same batch of workpieces 80 to be tested are repeatedly re-inspected, and the repetitive accuracy of the testing mechanism 50 is verified according to the results of multiple re-inspections.

[0152] See also Figures 1 to 3In some embodiments of the present application, there is a height difference between the first conveying mechanism 10 and the second conveying mechanism 20. The first conveying mechanism 10 and the second conveying mechanism 20 are connected in layers. The transfer mechanism 40 transports the workpiece 80 to be tested between the first conveying mechanism 10 and the second conveying mechanism 20 by lifting.

[0153] The first conveying mechanism 10 is connected to the second conveying mechanism 20 in layers, so that the first conveying mechanism 10 is located above or below the second conveying mechanism 20. When the workpiece 80 to be measured is conveyed by the first conveying mechanism 10 to the connection point between the first conveying mechanism 10 and the second conveying mechanism 20, the transfer mechanism 40 moves the workpiece 80 to the second conveying mechanism 20 by lifting. Similarly, when the workpiece 80 to be measured is conveyed by the second conveying mechanism 20 to the connection point between the first conveying mechanism 10 and the second conveying mechanism 20, the transfer mechanism 40 moves the workpiece 80 to the first conveying mechanism 10 by lifting.

[0154] In some embodiments of the present application, the height of the second conveying mechanism 20 is higher than the height of the first conveying mechanism 10. The transfer mechanism 40 is located in the space of the overlapping area between the first conveying mechanism 10 and the second conveying mechanism 20. The lowest point of the transfer mechanism 40 is lower than the height of the first conveying mechanism 10, and the highest point of the transfer mechanism 40 is higher than the height of the second conveying mechanism 20.

[0155] When the first conveying mechanism 10 conveys the workpiece 80 to be measured, the transfer mechanism 40 descends to a level below the first conveying mechanism 10 , thereby preventing the transfer mechanism 40 from blocking the workpiece 80 to be measured in the first conveying mechanism 10 .

[0156] When the first conveying mechanism 10 conveys the workpiece 80 to the top of the transfer mechanism 40, the transfer mechanism 40 rises, thereby lifting the workpiece 80 to be measured, and raising the workpiece 80 to the height of the second conveying mechanism 20, and then the workpiece 80 to be measured is transported to the second conveying mechanism 20 by the transfer mechanism 40, and the workpiece 80 to be measured is transported by the second conveying mechanism 20.

[0157] When the workpiece 80 to be measured is loaded from the second conveying mechanism 20, the second conveying mechanism 20 conveys the workpiece 80 to be measured. When the second conveying mechanism 20 conveys the workpiece 80 to be measured to the top of the transfer mechanism 40, the transfer mechanism 40 rises, and then lifts the workpiece 80 to be measured from the second conveying mechanism 20. After the transfer mechanism 40 lifts the workpiece 80 to be measured, it descends until the height of the transfer mechanism 40 is lower than the first conveying mechanism 10, and then the workpiece 80 to be measured is received by the first conveying mechanism 10, so that the workpiece 80 to be measured is transported from the second conveying mechanism 20 to the first conveying mechanism 10 through the transport mechanism 60.

[0158] See also Figures 3 to 5 In some embodiments of the present application, the detection device 100 is provided with a carrier assembly 70, and the carrier assembly 70 is used to load the workpiece 80 to be tested. The second conveying mechanism 20 includes: a first conveyor line device 21, a second conveyor line device 22 and an adjustment device 23. The second conveyor line device 22 is arranged side by side with the first conveyor line device 21. The adjustment device 23 is used to adjust the distance between the first conveyor line device 21 and the second conveyor line device 22. Among them, the distance between the first conveyor line device 21 and the second conveyor line device 22 includes a first distance and a second distance. The first distance is greater than the width of the carrier assembly 70, and the second distance is less than the width of the carrier assembly 70.

[0159] The workpiece 80 to be tested is loaded through the carrier assembly 70, thereby reducing the risk of damage to the workpiece 80 to be tested, and facilitating the fixing and positioning of the workpiece 80 to be tested. Multiple workpieces 80 to be tested can be loaded through the carrier assembly 70, so that the detection device 100 can continuously detect multiple workpieces 80 to be tested, thereby ensuring the continuity of the working process of the detection device 100 and improving the working efficiency of the detection device 100.

[0160] The first conveying mechanism 10 and the second conveying mechanism 20 convey the workpiece 80 by conveying the tray assembly 70 loaded with the workpiece 80 to be measured. The transfer mechanism 40 conveys the workpiece 80 by conveying the tray assembly 70 loaded with the workpiece 80 to be measured.

[0161] When the inspection device 100 inspects the workpiece 80 to be inspected, the first conveying mechanism 10 conveys the tray assembly 70 loaded with the workpiece 80 to be inspected.

[0162] When the workpiece 80 to be tested is to be unloaded midway, the tray assembly 70 is moved to the top of the transfer mechanism 40, and the transfer mechanism 40 is lifted upward, so that the tray assembly 70 is separated from the first conveying mechanism 10, and the height of the tray assembly 70 is increased. Before or during the lifting of the tray assembly 70, the adjustment device 23 adjusts the distance between the first conveying line device 21 and the second conveying line device 22 in the second conveying mechanism 20, so that the distance between the first conveying line device 21 and the second conveying line device 22 is greater than the width of the tray assembly 70, so that the tray assembly 70 can pass over the second conveying mechanism 20 and rise to a height higher than the second conveying mechanism 20. When the tray assembly 70 is lifted to a height higher than the second conveying mechanism 20 by the transfer mechanism 40, the adjustment device 23 adjusts the distance between the first conveying line device 21 and the second conveying line device 22 in the second conveying mechanism 20 again, so that the distance between the first conveying line device 21 and the second conveying line device 22 is smaller than the width of the tray assembly 70, so that after the transfer mechanism 40 is lowered to a height lower than the second conveying mechanism 20, the second conveying mechanism 20 can receive the tray assembly 70, so that the tray assembly 70 contacts the first conveying line device 21 and the second conveying line device 22, and the tray assembly 70 is transported by the second conveying mechanism 20. In this way, the tray assembly 70 is transported from the first conveying mechanism 10 to the second conveying mechanism 20 by the transfer mechanism 40.

[0163] When the workpiece 80 to be tested is to be loaded from the second conveying mechanism 20, the tray assembly 70 loaded with the workpiece 80 to be tested is placed on the second conveying mechanism 20, and the tray assembly 70 is received by the first conveying line device 21 and the second conveying line device 22. At this time, the distance between the first conveying line device 21 and the second conveying line device 22 is less than the width of the tray assembly 70. When the tray assembly 70 reaches the top of the transfer mechanism 40, the transfer mechanism 40 rises to a height higher than the second conveying mechanism 20, and then lifts up the tray assembly 70 at the second conveying mechanism 20. After the transfer mechanism 40 lifts up the tray assembly 70 at the second conveying mechanism 20, the adjustment device 23 adjusts the distance between the first conveying line device 21 and the second conveying line device 22, so that the distance between the first conveying line device 21 and the second conveying line device 22 is greater than the width of the tray assembly 70, so as to avoid the second conveying mechanism 20 from blocking the tray assembly 70. After the distance between the first conveyor line device 21 and the second conveyor line device 22 is greater than the width of the tray assembly 70, the transfer mechanism 40 is lowered to a height lower than the first conveyor mechanism 10. When the transfer mechanism 40 is lowered to a height lower than the first conveyor mechanism 10, the first conveyor mechanism 10 receives the tray assembly 70, and then the tray assembly 70 is transported by the first conveyor mechanism 10. In this way, the tray assembly 70 is transported from the second conveyor mechanism 20 to the first conveyor mechanism 10 by the transfer mechanism 40.

[0164] See also Figures 4 to 6In some embodiments of the present application, the second conveying mechanism 20 further includes a transmission rod assembly 241, a power assembly 24, a first transmission wheel assembly 242, a first connecting assembly 243, a second transmission wheel assembly 244 and a second connecting assembly 245. The power assembly 24 drives the transmission rod assembly 241 to rotate. The first transmission wheel assembly 242 is slidably connected to the transmission rod assembly 241, and the power assembly 24 drives the first conveying line device 21 to operate through the first transmission wheel assembly 242. The first connecting assembly 243 is used to connect the first transmission wheel assembly 242 to the first conveying line device 21, so that the first transmission wheel assembly 242 and the first conveying line device 21 move synchronously relative to the transmission rod assembly 241. The second transmission wheel assembly 244 is slidably connected to the transmission rod assembly 241, and the power assembly 24 drives the second conveying line device 22 to operate through the second transmission wheel assembly 244. The second connecting assembly 245 is used to connect the second transmission wheel assembly 244 to the second conveyor line device 22, so that the second transmission wheel assembly 244 and the second conveyor line device 22 move synchronously relative to the transmission rod assembly 241. The adjusting device 23 drives the first connecting assembly 243 and the second connecting assembly 245 to move along the transmission rod assembly 241.

[0165] During the operation of the second conveying mechanism 20, the power assembly 24 operates to drive the transmission rod assembly 241 to rotate, and then drives the first transmission wheel assembly 242 and the second transmission wheel assembly 244 to rotate synchronously through the transmission rod assembly 241. Since the first transmission wheel assembly 242 drives the first conveying line device 21 to operate, and the second transmission wheel assembly 244 drives the second conveying line device 22 to operate, therefore, during the process of the first transmission wheel assembly 242 and the second transmission wheel assembly 244 rotating synchronously, the first conveying line device 21 and the second conveying line device 22 operate synchronously.

[0166] The first connecting assembly 243 and the second connecting assembly 245 are driven to move along the transmission rod assembly 241 by the adjusting device 23, so that the whole formed by the first conveyor line device 21, the first connecting assembly 243 and the first transmission wheel assembly 242 moves under the guidance of the transmission rod assembly 241, and the whole formed by the second conveyor line device 22, the second connecting assembly 245 and the second transmission wheel assembly 244 moves under the guidance of the transmission rod assembly 241. In this way, the distance between the first conveyor line device 21 and the second conveyor line device 22 is adjusted by the adjusting device 23.

[0167] See also Figure 6In some embodiments of the present application, the first conveyor line device 21 includes: a first driven wheel assembly 211 and a first conveyor belt 212.

The second conveyor belt 222 is connected to the second driving wheel assembly 2441, and the second conveyor belt 222 rotates synchronously with the second driving wheel assembly 2441.

[0168] During the operation of the second conveying mechanism 20, the power assembly 24 drives the transmission rod assembly 241 to rotate, thereby driving the first driving wheel assembly 2421 and the second driving wheel assembly 2441 to rotate synchronously, thereby causing the first conveyor belt 212 and the second conveyor belt 222 to operate synchronously. The first conveyor belt 212 is supported and limited by a plurality of first driven wheel assemblies 211, thereby causing the first conveyor belt 212 to form a linear conveying channel. The second conveyor belt 222 is supported and limited by a plurality of second driven wheel assemblies 221, thereby causing the second conveyor belt 222 to form a linear conveying channel. During the process of the second conveying mechanism 20 conveying the carrier assembly 70, the carrier assembly 70 is in contact with the first conveyor belt 212 and the second conveyor belt 222 at the same time, and the first conveyor belt 212 and the second conveyor belt 222 are respectively located on both sides of the carrier assembly 70. The first conveyor belt 212 and the second conveyor belt 222 operate synchronously, thereby driving the carrier assembly 70 to move under the action of friction, so that the second conveying mechanism 20 conveys the carrier assembly 70.

[0169] In the process of adjusting the distance between the first conveyor line device 21 and the second conveyor line device 22 by the adjusting device 23, the adjusting device 23 drives the first active synchronous wheel assembly and the second active wheel assembly 2441 to move under the guidance of the transmission rod assembly 241 through the first connecting assembly 243 and the second connecting assembly 245, respectively, so that the whole formed by the first conveyor line device 21, the first connecting assembly 243 and the first driven wheel assembly 211 moves under the guidance of the transmission rod assembly 241, and the whole formed by the second conveyor line device 22, the second connecting assembly 245 and the second driven wheel assembly 221 moves under the guidance of the transmission rod assembly 241. In this way, the distance between the first conveyor line device 21 and the second conveyor line device 22 is adjusted by the adjusting device 23.

[0170] In some embodiments of the present application, the first conveyor line device 21 includes a first synchronous belt conveyor line, and the first synchronous belt conveyor line includes a first driving wheel assembly 2421, a first driven wheel assembly 211, and a first conveyor belt 212.

[0173] In some embodiments of the present application, the power assembly 24 includes a drive motor, which is connected to the transmission rod assembly 241 through a synchronous belt transmission device and drives the transmission rod assembly 241.

[0174] See also Figure 6 In some embodiments of the present application, the adjusting device 23 includes: a first pushing component 231, a second pushing component 232 and a driving component 233. The first pushing component 231 is connected to the first conveying line device 21. The second pushing component 232 is connected to the second conveying line device 22. The driving component 233 is used to drive the first pushing component 231 and the second pushing component 232 to move closer to or away from each other.

[0175] The driving component 233 drives the first pushing component 231 and the second pushing component 232 to move closer to or farther from each other, thereby making the first conveyor line device 21 and the second conveyor line device 22 move closer to or farther from each other, thereby adjusting the distance between the first conveyor line device 21 and the second conveyor line device 22.

[0176] In some embodiments of the present application, the driving assembly 233 includes a finger cylinder, the first pushing assembly 231 is installed on the first clamping jaw of the finger cylinder, and the second pushing assembly 232 is installed on the second clamping jaw of the finger cylinder. When the first clamping jaw and the second clamping jaw of the finger cylinder are separated from each other, the first pushing assembly 231 and the second pushing assembly 232 are separated from each other, thereby increasing the distance between the first conveyor line device 21 and the second conveyor line device 22. When the first clamping jaw and the second clamping jaw of the finger cylinder are close to each other, the first pushing assembly 231 and the second pushing assembly 232 are close to each other, thereby reducing the distance between the first conveyor line device 21 and the second conveyor line device 22. In this way, the distance between the first conveyor line device 21 and the second conveyor line device 22 is adjusted by the adjusting device 23.

[0177] In some embodiments of the present application, the transfer mechanism 40 includes: a lifting plate assembly 41 and a lifting power assembly 42. The lifting plate assembly 41 is used to receive the workpiece 80 to be measured. The lifting power assembly 42 is used to drive the lifting plate assembly 41 to rise and fall. The lowest point of the lifting plate assembly 41 is lower than the height of the first conveying mechanism 10, and the highest point of the lifting plate assembly 41 is higher than the height of the second conveying mechanism 20. The width of the lifting plate assembly 41 is less than the distance between the first conveying line device 21 and the second conveying line device 22.

[0178] When the transfer mechanism 40 is transporting the workpiece 80 to be measured, the lifting plate assembly 41 is driven to rise or fall by the lifting power assembly 42 , thereby transporting the workpiece 80 to be measured between the first conveying mechanism 10 and the second conveying mechanism 20 .

[0179] In some embodiments of the present application, the lifting power assembly 42 includes an electric cylinder drive module.

[0180] The lifting plate assembly 41 is driven to rise or fall by the electric cylinder driving module, so as to transport the workpiece 80 to be measured between the first conveying mechanism 10 and the second conveying mechanism 20 .

[0181] In some embodiments of the present application, the first conveying mechanism 10 is provided with a first blocking device 11 , and the first blocking device 11 is used to block the workpiece 80 to be measured under the second conveying mechanism 20 .

[0182] After the first conveying mechanism 10 conveys the workpiece 80 to the bottom of the second conveying mechanism 20, the workpiece 80 is blocked by the first blocking device 11, so that the workpiece 80 is stopped below the second conveying mechanism 20. The blocking of the first blocking device 11 not only stops the workpiece 80 from moving, but also stops the workpiece 80 at the expected position, so that the workpiece 80 can smoothly enter the second conveying mechanism 20. When the stop position of the workpiece 80 is offset, the position of the first blocking device 11 can be adjusted, so that the workpiece 80 is stopped at the expected position.

[0183] After the first blocking device 11 blocks the workpiece 80 to be measured, the first conveying mechanism 10 continues to operate for a period of time and then stops operating. In this way, on the one hand, the carrier assembly 70 loaded with the workpiece 80 to be measured can be close to the first blocking device 11, reducing the error of the stop position of the carrier assembly 70, and on the other hand, the relative friction time between the carrier assembly 70 and the first conveying mechanism 10 is reduced, thereby reducing the degree of wear of the first conveying mechanism 10 and extending the service life of the first conveying mechanism 10.

[0184] See also Figures 1 to 3 In some embodiments of the present application, the first blocking device 11 includes a first blocking cylinder and a first blocking block. The first blocking cylinder drives the first blocking block to extend or retract, thereby enabling the first blocking device 11 to block and release the workpiece 80 to be measured.

[0185] In some embodiments of the present application, there are at least two second conveying mechanisms 20, which are arranged along the conveying direction of the first conveying mechanism 10. The conveying direction of the second conveying mechanism 20 includes the feeding direction of the detection device 100 and the discharging direction of the detection device 100.

[0186] The plurality of second conveying mechanisms 20 are used to load and unload the workpieces 80 to be tested respectively, thereby avoiding the occurrence of equal situations in the loading and unloading processes of the workpieces 80 to be tested, thereby improving the working efficiency of the detection equipment 100.

[0187] In some embodiments of the present application, the first conveying mechanism 10 is provided with a second blocking device 12 , and the second blocking device 12 is used to block the tray assembly 70 within the working range of the transport mechanism 60 .

[0188] After the first conveying mechanism 10 conveys the workpiece 80 to be measured to the working range of the conveying mechanism 60, the second blocking device 12 blocks the tray assembly 70, so that the tray assembly 70 stays within the working range of the conveying mechanism 60, so that the conveying mechanism 60 can pick up and place the workpiece 80 to be measured at the tray assembly 70. The blocking of the second blocking device 12, on the one hand, stops the movement of the tray assembly 70, and on the other hand, stops the tray assembly 70 at the expected position, so that the conveying mechanism 60 can accurately take out the workpiece 80 to be measured from the tray assembly 70 or put the workpiece 80 to be measured into the tray assembly 70. When the stop position of the tray assembly 70 is offset, the position of the second blocking device 12 can be adjusted, so that the tray assembly 70 stays at the expected position.

[0189] After the second blocking device 12 blocks the workpiece 80 to be measured, the first conveying mechanism 10 continues to operate for a period of time and then stops operating. In this way, on the one hand, the carrier assembly 70 can be close to the second blocking device 12, reducing the error of the stop position of the carrier assembly 70, and on the other hand, the relative friction time between the carrier assembly 70 and the first conveying mechanism 10 is reduced, thereby reducing the degree of wear of the first conveying mechanism 10 and extending the service life of the first conveying mechanism 10.

[0190] In some embodiments of the present application, the second blocking device 12 includes a second blocking cylinder and a second blocking block. The second blocking cylinder drives the second blocking block to extend or retract, thereby enabling the second blocking device 12 to block and release the carrier assembly 70.

[0191] See also Figures 1 to 3 In some embodiments of the present application, the first conveying mechanism 10 is provided with a lifting device 13, and the lifting device 13 is used to lift and lower the carrier assembly 70 so that the carrier assembly 70 is separated from or contacts the first conveying mechanism 10.

[0192] When the tray assembly 70 is blocked in the first conveying mechanism 10, the tray assembly 70 is lifted up by the lifting device 13, and Genori makes the tray assembly 70 separate from the first conveying mechanism 10. The tray assembly 70 is separated from the first conveying mechanism 10 by the lifting device 13, and then the tray assembly 70 is supported by the lifting device 13 to prevent the tray assembly 70 from shaking, thereby ensuring the position accuracy of the tray assembly 70 and ensuring that the conveying mechanism 60 can accurately pick up and place the workpiece 80 to be measured in the tray assembly 70.

[0193] See also Figures 1 to 3 and Fig.11 In some embodiments of the present application, the lifting device 13 is provided with a positioning pin 14 , and the carrier assembly 70 is provided with a positioning hole 71 , and the positioning pin 14 is adapted to the positioning hole 71 .

[0194] The cooperation between the positioning pin 14 and the positioning hole 71 improves the position accuracy of the carrier assembly 70 after the lifting device 13 lifts the carrier assembly 70 .

[0195] See also Figure 1 to Figure 2 In some embodiments of the present application, the detection device 100 also includes a third conveying mechanism 30, the feeding part of the third conveying mechanism 30 is located in the discharge range of the handling mechanism 60, and the third conveying mechanism 30 is used to discharge unqualified workpieces 80 to be tested.

[0196] When unqualified products are detected, the transport mechanism 60 puts the unqualified products into the third conveying mechanism 30 , and the unqualified workpieces are taken off the production line through the third conveying mechanism 30 .

[0197] In some embodiments of the present application, the third conveying mechanism 30 includes at least one conveying assembly 31. The number of conveying assemblies 31 matches the number of detection index categories of the workpiece to be tested 80. When the workpiece to be tested 80 is detected to be unqualified, the handling mechanism 60 places the workpiece to be tested 80 into the corresponding conveying assembly 31 according to the detection index category.

[0198] Each workpiece 80 to be tested has multiple testing indicators, such as the horizontal relative distance of feature points, the vertical relative distance, the hole spacing, the hole depth, the diameter, the fillet, the thickness and other hard indicators of the drawing specifications, as well as the height of the pin, whether the number is missing, the verticality and the position, including the minimum spacing between the pin holes and other dimensions. The testing indicators of the workpiece 80 to be tested are classified. When unqualified products are detected, the workpieces 80 to be tested with different unqualified testing indicator categories are placed in different conveying components 31 according to the testing indicator categories, and the workpieces 80 to be tested with different unqualified testing indicator categories are conveyed by different conveying components 31 respectively, so that the workpieces 80 to be tested can be repaired later.
