In order to ensure the smooth operation of the production process, it is necessary to ensure the accuracy of the positioning structure of the carrier components.

Furthermore, the controller is configured to control the conveying device to transport the inspected carrier to the main body of the line when the number of times the inspection device detects deviation values ​​of any positioning structure of the carrier that meet the second preset condition reaches the preset number.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] The following is for reference. Figures 1-5 The present invention describes a testing mechanism 1 of a production line 10 according to an embodiment of the present invention, and a production line 10 having the same.

[0029] like Figures 1-4 As shown, the production line 10 according to the present invention includes a testing mechanism 1. The production line 10 includes a main body 2 and a maintenance line 3. The testing mechanism 1 includes a frame body 11, a vibration damper 12, a conveying device 13, and a testing device 14. The vibration damper 12 is adapted to be installed on the platform 21 of the main body 2 and supports the frame body 11. The conveying device 13 is installed on the frame body 11 and is used to receive the carrier 101 conveyed from the main body 2 to the testing device 14. The testing device 14 is installed on the frame body 11 and is used to test the accuracy of the positioning structure 1011 of the carrier 101 received by the conveying device 13. The conveying device 13 is also used to convey the carrier 101 after testing by the testing device 14 to the main body 2 or the maintenance line 3.

[0030] Among them, such as Figure 1 and Figure 2 As shown, production line 10 can be used to transport workpieces. For example, production line 10 can transport vehicle parts (body frame, lower body, etc.) from the welding workshop to the painting workshop. The main body 2 of production line 10 can include multiple transport sections, which can be, but are not limited to, the lower line 22, the body line 23, and the assembly line 24. The multiple transport sections are arranged sequentially. Production line 10 can sequentially process workpieces through multiple transport sections and transport the processed workpieces to the painting area 25. Afterward, the carrier 101 can return to the lower line 22 through the empty slide area 26. The detection mechanism 1 can be set between the empty slide area 26 and the lower line 22. The carrier 101 that has passed through the detection mechanism 1 can be subjected to accuracy detection to determine whether the accuracy of the positioning structure 1011 of the carrier 101 meets the requirements. As some embodiments of this utility model, the carrier 101 can be a skid.

[0031] like Figure 3 and Figure 4 As shown, the detection device 14 is located on the frame body 11. As some embodiments of this utility model, the detection device 14 can be welded, screwed, etc., to the frame body 11. The detection device 14 can detect the accuracy of the positioning structure 1011 of the carrier 101 received by the conveying device 13. The accuracy of the positioning structure 1011 can be understood as the deviation value between the spatial position information (shape, position, etc.) of the positioning structure 1011 during detection and the preset spatial position information. If the deviation value is small, the accuracy of the positioning structure 1011 is considered to meet the requirements. If the deviation value is relatively large, it is necessary to issue a warning or perform maintenance according to the calibration. The detection device 14 can automatically detect and provide feedback on the detection results so that the operator can understand the actual situation of the carrier 101.

[0032] like Figure 3 and Figure 4 As shown, the conveying device 13 is located on the frame body 11. As some embodiments of this utility model, the conveying device 13 is movable or rotatable relative to the frame body 11. The conveying device 13 is used to receive the carrier 101 conveyed from the line body 2 to the testing device 14 and can convey the carrier 101 to the testing device 14. After the testing is completed, the conveying device 13 is also used to convey the carrier 101 after testing by the testing device 14 to the line body 2 or the maintenance line 3 (the carrier 101 can be conveyed to the line body 2 or the maintenance line 3 according to the testing results).

[0033] As some embodiments of this utility model, the conveying device 13 may include multiple rollers, a driving component, and a transmission assembly. There may be two, three, ten, or more rollers. The transmission assembly is connected between the multiple rollers and the driving component. The driving component drives the transmission assembly to rotate the rollers around their own axes. When the driving component is working, its output end rotates to drive the corresponding rollers to rotate around their own axes. The carrier 101 can be placed on the rollers, and there is friction between the rollers and the carrier 101. This friction can serve as the power source for the movement of the carrier 101, thereby conveying the carrier 101 to the line body 2 or the maintenance line 3.

[0034] In some embodiments of this utility model, the conveying device 13 may include multiple rollers, a driving component, and a transmission assembly. There may be two, three, ten, or more rollers. The transmission assembly is driven between the multiple rollers and the driving component. Multiple rollers are rotatably mounted on the frame body 11 and arranged sequentially along the extension direction of the line body 2 (from upstream to downstream). The driving component is driven by at least one roller. The rollers may have gears, and any two adjacent rollers are driven together. Any two adjacent rollers have mating parts (e.g., but not limited to meshing teeth, gears, etc.). Any two adjacent rollers can be driven together by a belt or transmission chain. When the driving component is working, its output end rotates to drive at least one roller to rotate, thereby driving the remaining rollers to rotate, which in turn moves the carrier 101, achieving the effect of conveying the line body 2 or the maintenance line 3.

[0035] like Figure 3 and Figure 4 As shown, the vibration damper 12 is disposed between the platform 21 of the main body 2 and the frame body 11. The vibration damper 12 is disposed on the platform 21 of the main body 2 and supports the frame body 11. The vibration damper 12 can be constructed as a damper, air spring, etc. The vibration damper 12 can elastically deform to absorb the vibration from the platform 21, thereby reducing the frequency and amplitude of the vibration transmitted to the frame body 11, reducing the vibration of the detection device 14 and the positioning structure 1011, and improving the detection accuracy. Furthermore, by disposing of both the conveying device 13 and the detection device 14 on the frame body 11, and by using the vibration damper 12 to support the frame body 11, the vibration frequency and amplitude of the vibration from the platform 21 experienced by the conveying device 13, the detection device 14, and the frame body 11 are the same, which can improve the detection accuracy.

[0036] It should be noted that the larger the production capacity of production line 10, the more support components 101 are required on production line 10. For example, for a workshop with a capacity of 60 JPH (Jobs Per Hour), the number of support components 101 is generally no less than 400. During the operation of production line 10, the accuracy of the positioning structure 1011 of support components 101 will change, requiring timely detection and repair to ensure the normal operation of production line 10 and reduce production risks. This utility model, by inspecting each support component 101 on production line 10, can promptly detect and repair support components 101 without affecting the production cycle of production line 10.

[0037] In the above embodiments, the testing mechanism 1 of this application can carry the carrier 101 conveyed by the main body 2 and test the accuracy of the positioning structure 1011 of the carrier 101. There is no need to move the carrier 101 to the maintenance line 3 for testing. The tested carrier 101 can be conveyed to the main body 2 or the maintenance line 3 according to the test results. Thus, the test can be carried out during the normal operation of the production line 10 without affecting the normal operation of the production line 10. Furthermore, it can be checked one by one, which is conducive to improving the testing efficiency and reducing the ineffective working hours.

[0038] In some embodiments of this utility model, the detection mechanism 1 of the production line 10 further includes: a clamping device, which is disposed on the frame body 11 and is used to clamp the carrier 101 received by the conveying device 13.

[0039] The clamping device can be installed on the frame body 11. As some embodiments of this utility model, the clamping device can be welded or snapped to the frame body 11. The clamping device can be used to clamp the carrier 101 received by the conveying device 13 so that the carrier 101 received by the conveying device 13 does not move relative to the detection device 14, so that the accuracy of the positioning structure 1011 of the carrier 101 can be accurately detected by the detection device 14.

[0040] As some embodiments of this utility model, the clamping device can be constructed as an electro-hydraulic cylinder, which has a retractable output shaft. Multiple clamping devices can be distributed on both sides of the carrier 101 along the first direction. When it is necessary to clamp the carrier 101, the electro-hydraulic cylinder operates to extend its output shaft, so that the output shaft abuts against the carrier 101 and limits its position. The output shafts of multiple clamping devices can simultaneously limit the carrier 101 to hold the carrier 101 received by the conveying device 13, reducing the risk of the carrier 101 shaking during the detection process and improving detection accuracy.

[0041] In some other embodiments of this utility model, the clamping device may include a drive motor and a telescopic rod, which can be connected by transmission. The telescopic rod may have a gripper, and the drive motor can drive the telescopic rod to extend and retract, thereby moving the gripper and clamping the carrier 101 to reduce the risk of the carrier 101 shaking during the detection process and improve the detection accuracy.

[0042] In some embodiments of this utility model, such as Figures 3-5 As shown, the detection device 14 includes multiple vision cameras 141, all of which are used to detect the accuracy of the positioning structure 1011 of the carrier 101 received by the conveying device 13.

[0043] The number of vision cameras 141 can be two, four, six, etc. The number of vision cameras 141 can be the same as the number of positioning structures 1011 and correspond one-to-one. Multiple vision cameras 141 can be used to detect the accuracy of the positioning structure 1011 of the carrier 101 received by the conveying device 13 to obtain multiple detection results, so as to judge from multiple aspects whether the accuracy of the positioning structure 1011 of the carrier 101 meets the requirements, so as to further improve the accuracy of the detection results.

[0044] As some embodiments of this utility model, such as Figure 4 As shown, the inspection mechanism 1 also includes a vision control cabinet 15, which can communicate with the vision camera 141. The control system of the vision control cabinet 15 can acquire the monitoring data of the vision camera 141, compare the monitoring data with preset data, and display the comparison results on the screen. Each vision camera 141 can detect the accuracy of the positioning structure 1011 of the corresponding carrier 101, and can upload the detected structure to the vision control cabinet 15. The vision control cabinet 15 can display the detection results so that the operators of the production line 10 can know the detection results, thereby improving the automation and intelligence level of the inspection mechanism 1.

[0045] As some embodiments of this utility model, such as Figure 5 As shown, the positioning structure 1011 may include a main pin 10111 and an auxiliary pin 10112. Both the main pin 10111 and the auxiliary pin 10112 are used to cooperate with the corresponding structure of the workpiece to fix the workpiece to the carrier 101. The position of the main pin 10111 can be fixed, while the position of the auxiliary pin 10112 can be adjusted according to the model of the workpiece. Each auxiliary pin 10112 in a different position corresponds to a vision camera 141, so that the distance between the vision camera 141 and the corresponding auxiliary pin 10112 remains unchanged during inspection, and the variables during inspection can be controlled without moving the vision camera 141, which is beneficial to improving the inspection accuracy.

[0046] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, along the first direction, some visual cameras 141 are located on one side of the conveying device 13, and other visual cameras 141 are located on the other side of the conveying device 13.

[0047] The multiple vision cameras 141 can be divided into two parts. Along the first direction, one part of the vision cameras 141 can be located on one side of the conveying device 13, and the other part of the vision cameras 141 can be located on the other side of the conveying device 13. The vision cameras 141 can emit lasers towards the positioning structure 1011. The vision cameras 141 can distinguish the difference between the position where the laser falls on the positioning structure 1011 and the preset position to determine the accuracy. This arrangement can shorten the distance between each vision camera 141 and the corresponding positioning structure 1011 to be detected, and can reduce the risk of the vision cameras 141 being blocked, so as to ensure the effectiveness of the detection process and the accuracy of the detection results.

[0048] In some embodiments of this utility model, such as Figure 4 As shown, the frame body 11 includes: a first body 111 and a second body 121. A shock absorber 12 supports the first body 111. A conveying device 13 is disposed on the first body 111. Along the first direction, the second body 121 is provided on both sides of the first body 111. The lower end of the second body 121 is connected to the first body 111. A vision camera 141 is disposed on the upper end of the second body 121.

[0049] The first body 111 and the second body 121 can be connected. In some embodiments of this utility model, the first body 111 and the second body 121 can be integrally formed. The conveying device 13 can be located on the first body 111. There can be two second bodies 121; each side of the first body 111 can have a second body 121. The lower end of the second body 121 ( Figure 4 The frame body 11 (shown in the up-down direction) is connected to the first main body 111. The upper end of the second main body 121 can be fixed with a vision camera 141. This arrangement can make the frame body 11, vision camera 141, and conveying device 13 an integrated structure. The frame body 11, vision camera 141, and conveying device 13 are subjected to the same vibration frequency and amplitude from the platform 21, so as to reduce the relative movement between the frame body 11, vision camera 141, and conveying device 13, thereby improving the detection accuracy.

[0050] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the damper 12 is constructed as a damping damper and there are multiple dampers.

[0051] Multiple vibration dampers 12 can be provided, and the multiple vibration dampers 12 are evenly distributed between the platform 21 and the frame body 11 of the line body 2 to absorb the vibration transmitted from the platform 21. Multiple vibration dampers 12 can improve the absorption effect, further reduce the frequency and amplitude of the vibration transmitted to the frame body 11, reduce the vibration of the detection device 14 and the positioning structure 1011, and further improve the detection accuracy.

[0052] The vibration damper 12 can be constructed as a damping vibration damper. The damping vibration damper has the advantages of high frequency absorption of vibration energy, high safety, good durability, and resistance to bending and tilting. It can reduce the vibration frequency and amplitude, which is conducive to improving the reliability of the vibration damper 12.

[0053] In some embodiments of this utility model, the conveying device 13 includes: a plurality of rollers, a driving member, and a transmission assembly. The transmission assembly is connected between the driving member and the plurality of rollers. The driving member is used to drive the transmission assembly to rotate the rollers.

[0054] The rollers can be two, three, ten, or more. A transmission assembly connects multiple rollers and a driving component. The driving component drives the transmission assembly to rotate the rollers around their own axes. When the driving component is working, its output end rotates to drive the corresponding rollers to rotate around their own axes. The carrier 101 can be placed on the rollers. There is friction between the rollers and the carrier 101. This friction can serve as the power source for moving the carrier 101, thereby conveying the carrier 101 to the line body 2 or the maintenance line 3.

[0055] In some embodiments of this utility model, the detection mechanism 1 of the production line 10 further includes a controller. The controller is communicatively connected to the conveying device 13 and the detection device 14. The controller is configured to control the conveying device 13 to convey the carrier 101 detected by the detection device 14 to the line body 2 when the deviation values ​​of all positioning structures 1011 of the carrier 101 detected by the detection device 14 meet the first preset condition or the number of times the deviation value of any positioning structure 1011 meets the second preset condition is less than a preset number. The controller is also configured to control the conveying device 13 to convey the carrier 101 detected by the detection device 14 to the line body 2 and issue a first-level alarm when the number of times the deviation value of any positioning structure 1011 of the carrier 101 detected by the detection device 14 meets the second preset condition reaches a preset number. The controller is further configured to control the conveying device 13 to convey the carrier 101 detected by the detection device 14 to the maintenance line 3 and issue a second-level alarm when the deviation value of any positioning structure 1011 of the carrier 101 detected by the detection device 14 meets the third preset condition.

[0056] The first preset condition is that the deviation value of all positioning structures 1011 is less than or equal to the first preset value; the second preset condition is that the deviation value of any positioning structure 1011 is greater than the first preset value and less than or equal to the second preset value; and the third preset condition is that the deviation value of any positioning structure 1011 is greater than the second preset value, and the second preset value is greater than the first preset value.

[0057] The controller can communicate with both the conveying device 13 and the detection device 14 (e.g., wired or wireless connection). The controller can control the movement of the conveying device 13 and the operation of the detection device 14. The controller can also control the movement of the conveying device 13 based on the detection results of the detection device 14. The controller also has an early warning function to remind the operator whether the detection results need attention. The controller has preset conditions, including a first preset condition, a second preset condition, and a third preset condition. The detection device 14 can detect the accuracy of all positioning structures 1011 and transmit the detection results to the controller. The controller can compare the difference between the detection results and the preset conditions and calculate the deviation value of the positioning structure 1011. The first preset condition is that the deviation value of all positioning structures 1011 is less than or equal to a first preset value, which can be set to 1 mm. The second preset condition is that the deviation value of any positioning structure 1011 is greater than the first preset value and less than or equal to the second preset value, which can be set to 2 mm. The third preset condition is that the deviation value of any positioning structure 1011 is greater than the second preset value, and the second preset value is greater than the first preset value. The controller has a preset number of times, which can be set to two, three, four, etc. In this invention, the preset number of times can be set to three.

[0058] Specifically, when the deviation values ​​of all positioning structures 1011 of the carrier 101 detected by the detection device 14 meet the first preset condition, or when the number of times the deviation value of any positioning structure 1011 meets the second preset condition is less than the preset number, it indicates that the deviation values ​​of all positioning structures 1011 of the carrier 101 are small, the accuracy of all positioning structures 1011 meets the operational requirements, the carrier 101 can continue to be used, and the controller can control the conveying device 13 to convey the carrier 101 detected by the detection device 14 to the line body 2.

[0059] When the number of times the deviation value of any positioning structure 1011 of the carrier 101 is detected by the detection device 14 meets the second preset condition reaches a preset number, it indicates that the deviation value of some positioning structures 1011 of the carrier 101 is not large. The deviation value may come from the influence of random factors in the detection process. The accuracy of some positioning structures 1011 may be in a state of system error fluctuation. The carrier 101 can continue to be used. The controller can control the conveying device 13 to convey the carrier 101 detected by the detection device 14 to the line body 2 and issue a first-level alarm. The first-level alarm can be used to warn the operator that the carrier 101 needs to be continuously monitored.

[0060] When the detection device 14 detects that the deviation value of any positioning structure 1011 of the carrier 101 meets the third preset condition, it indicates that the deviation value of some positioning structures 1011 of the carrier 101 is large and exceeds the upper limit of use. If the carrier 101 continues to operate, it will cause a malfunction. The controller can control the conveying device 13 to transport the carrier 101 detected by the detection device 14 to the maintenance line 3 and issue a secondary alarm. The secondary alarm can be used to warn the operator that the carrier 101 needs to be repaired.

[0061] Therefore, by comparing the difference between the test results and the preset conditions and calculating the deviation value of the positioning structure 1011, a large number of carrier components 101 can be classified and tested in real time and in a timely manner. Carrier components 101 in good condition are automatically released, while carrier components 101 that need attention are issued an alarm. Carrier components 101 that need maintenance are moved out of the production line 10 to the maintenance line 3, thereby reducing the management difficulty of the production line 10 and achieving the effects of preventing failures, facilitating maintenance, and optimizing labor hours.

[0062] The production line 10 according to this utility model embodiment includes the detection mechanism 1 of the production line 10 described in the above embodiment. The detection mechanism 1 of this application can receive the carrier 101 conveyed by the main body 2 and detect the accuracy of the positioning structure 1011 of the carrier 101, without needing to move the carrier 101 to the maintenance line 3 for detection. Furthermore, based on the detection results, the detected carrier 101 can be conveyed to the main body 2 or the maintenance line 3. Therefore, detection can be performed during the normal operation of the production line 10 without affecting its normal operation, and each component can be checked individually, which helps improve detection efficiency and reduce ineffective working hours.

[0063] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the production line 10 also includes: a line body 2, a maintenance line 3, and a conveying device 13 for receiving the carrier 101 conveyed from the line body 2 to the testing mechanism 1. The conveying device 13 is also used to convey the tested carrier 101 to the line body 2 or the maintenance line 3. The maintenance line 3 is used to convey the repaired carrier 101 to the line body 2 located upstream of the testing mechanism 1.

[0064] Among them, such as Figure 1 and Figure 2As shown, production line 10 can be used to transport workpieces. For example, production line 10 can transport vehicle parts (body frame, lower body, etc.) from the welding workshop to the painting workshop. The main body 2 of production line 10 can include multiple transport sections, which can be, but are not limited to, the lower line 22, the body line 23, and the assembly line 24. The multiple transport sections are arranged sequentially. Production line 10 can process workpieces sequentially through multiple transport sections and transport the processed workpieces to the painting area 25. After that, the carrier 101 can return to the lower line 22 through the empty sliding area 26. The detection mechanism 1 can be set between the empty sliding area 26 and the lower line 22. The carrier 101 that has passed through the detection mechanism 1 can be subjected to accuracy detection by the detection mechanism 1 to determine whether the accuracy of the positioning structure 1011 of the carrier 101 meets the requirements.

[0065] After inspection, for carriers 101 that can continue to be used, the controller controls the conveying device 13 to transport the carriers 101 inspected by the inspection device 14 to the main body of the line 2. For carriers 101 that need to be repaired, the controller controls the conveying device 13 to transport the carriers 101 inspected by the inspection device 14 to the maintenance line 3. The maintenance line 3 has a maintenance area 31 where maintenance can be carried out. After maintenance, the maintenance line 3 can be used to transport the repaired carriers 101 to the main body of the line 2 located upstream of the inspection mechanism 1, so that the inspection device 14 can detect whether the repaired carriers 101 meet the accuracy requirements, so as to further ensure the reliability of the carriers 101. The repaired carriers 101 can also be transported back to the main body of the line 2.

[0066] It should be noted that it takes about 25 seconds for the carrier 101 to enter and leave the visual inspection station, about 10 seconds for the clamping device to close and open, and about 10 seconds for the inspection device 14 to perform measurement and calculation. The total time is about 40 seconds, which fully meets the cycle time requirements for a production line 10 with a capacity of 60 JHP.
