[0021] Example Reference Figures 1-5 The present invention provides an optical inspection workstation, including a workstation body, a six-axis robot 100 mounted on the workstation body, and an optical measuring camera 200 mounted on the six-axis robot 100. A frame fixing assembly 300 is provided on each side of the six-axis robot 100, and the frame fixing assembly 300 is used to fix the frame. The frame fixing assembly 300 includes a front fixing assembly 301 and a rear fixing assembly 302. The front fixing assembly 301 includes a front support platform 3011 and a pressing cylinder 3012. The pressing cylinder 3012 is provided with a pressing rod 3016. The pressing rod 3016 cooperates with the front support platform 3011 to clamp the frame. The rear fixing assembly 302 includes a rear support platform 3023 and a rotary cylinder 3021; ​​a support shaft 3024 is provided on the rear support platform 3023, and the support shaft 3024 is used to insert into the bottom bracket of the frame; The rotary cylinder 3021 is provided with a rotary fixing member 3022, which is used to abut against the bottom bracket of the frame; the rotary fixing member 3022 cooperates with the support shaft 3024 to clamp the frame.

[0022] In some embodiments, the main body of the optical inspection workstation is equipped with a six-axis robot 100, and an optical measuring camera 200 is mounted on the six-axis robot 100. The six-axis robot 100 measures the vehicle frame through the optical measuring camera 200.

[0023] To improve measurement efficiency, frame fixing components 300 are provided on both sides of the six-axis robot 100. The frame fixing components 300 are used to fix the frame. When the six-axis robot 100 measures the frame on one frame fixing component 300, the other frame fixing component 300 fixes the frame to be measured, thereby enabling the six-axis robot 100 to alternately measure the frame on the two frame fixing components 300, thus improving measurement efficiency.

[0024] The front fixing component 301 and the rear fixing component 302 of the frame fixing assembly 300 cooperate to fix the frame, so that the frame is fixed on the frame fixing assembly 300.

[0025] When it is necessary to fix the frame to the frame fixing assembly 300, the support shaft 3024 is inserted into the bottom bracket of the frame, and the frame is placed on the front support platform 3011; the pressure cylinder 3012 causes the pressure rod 3016 to move downward and press down on the frame; that is, the pressure rod 3016 cooperates with the front support to fix the frame in the vertical direction.

[0026] After the support shaft 3024 is inserted into the bottom bracket of the frame, the rotary cylinder 3021 causes the rotating fixing member 3022 to rotate and apply pressure to the bottom bracket of the frame, thereby achieving the fixation of the frame in the left and right directions.

[0027] Reference Figure 2 In an optional embodiment, the rotating fixing member 3022 includes an upper fixing arm 30221 and a lower fixing arm 30222, both of which have fixing posts, which are used to abut against the bottom bracket of the vehicle frame.

[0028] In some embodiments, since there is a through hole at the bottom bracket, the rotating fastener 3022 needs to apply an external force evenly to the bottom bracket of the frame; the rotating fastener 3022 is provided with an upper fixing arm 30221 and a lower fixing arm 30222, and both the upper fixing arm 30221 and the lower fixing arm 30222 are screwed with fixing posts; this makes it convenient to replace worn fixing posts.

[0029] Two fixing posts apply external force to the bottom bracket, thereby keeping the support shaft 3024 inserted at the bottom bracket, and thus the frame can be firmly fixed to the frame fixing assembly 300. In an optional embodiment, a detection arm 3013 is provided on the pressing cylinder 3012, and a detection sensor 3015 is provided on the detection arm 3013. The detection sensor 3015 moves up and down synchronously with the pressing rod 3016, and the detection sensor 3015 is used to detect the vehicle frame.

[0030] In some embodiments, the movable end of the pressing cylinder 3012 is provided with a detection arm 3013, and a detection sensor 3015 is provided on the detection arm 3013; the detection sensor 3015 moves up and down with the movable end of the pressing cylinder 3012, and the detection sensor 3015 can detect whether the frame is placed, so as to avoid the pressing rod 3016 from falling excessively if the frame is not placed.

[0031] In an optional embodiment, the detection arm 3013 is provided with a mounting arm 3014, and the detection sensor 3015 is disposed on the mounting arm 3014.

[0032] A mounting arm 3014 is provided on the detection arm 3013, and the detection sensor 3015 is mounted on the mounting arm 3014. In order to achieve fine adjustment of the detection sensor 3015, the detection sensor 3015 can be installed at different positions on the mounting arm 3014, thereby achieving fine adjustment of the position of the detection sensor 3015 and ensuring that the detection sensor 3015 can detect the frame.

[0033] In an optional embodiment, a support surface is provided on the rear support platform 3023, and the vehicle frame abuts against the support surface of the rear support platform 3023.

[0034] In some embodiments, the rear support platform 3023 has a support surface. When the support shaft 3024 is inserted into the bottom bracket of the frame, the frame abuts against the support surface of the rear support platform 3023. The rotating fixing member 3022 applies pressure to the frame to keep the frame abutting against the support surface, thus ensuring the fixation of the frame.

[0035] Reference Figure 1 and Figure 3 In an optional embodiment, an auxiliary bracket 400 is also included, which is disposed on one side of the frame fixing assembly 300.

[0036] In order to place the frame on the frame fixing assembly 300, an auxiliary bracket 400 is provided on one side of the frame fixing assembly 300. When the staff needs to fix the frame on the frame fixing assembly 300, the frame is first placed on the auxiliary bracket 400, and then the bottom bracket of the frame is aligned with the support shaft 3024 and pushed onto the front support platform 3011.

[0037] Reference Figure 4 In an optional implementation, it also includes two safety monitoring components 600, with one safety monitoring component 600 respectively provided on each side of the workstation body in the first direction; The first direction is the direction from one frame fixing assembly 300 to another frame fixing assembly 300.

[0038] To ensure that no personnel are near the six-axis robot 100 when it is performing measurements, each frame fixing component 300 corresponds to a safety monitoring component 600. When the safety monitoring component 600 is activated, the six-axis robot 100 will only perform measurement work if no personnel are detected. The safety monitoring component also has an alarm function.

[0039] The safety monitoring component 600 can be a grating sensor, light curtain sensor, or infrared beam sensor, etc., based on existing technologies.

[0040] In an optional embodiment, a protective net 500 is also included, with protective nets 500 provided on both sides of the workstation body in a first direction.

[0041] In an optional embodiment, a control system 900 and a display system 800 are also included, wherein the control system 900 is used to control the six-axis robot 100, and the display system 800 is used to display the measurement results.

[0042] Workers place the vehicle frame to be measured on the established coordinate system of the product positioning benchmark. A six-axis articulated arm robot then uses an optical measuring camera to capture images of the workpiece points. The entire measurement process is controlled by a PLC control system, requiring no human intervention. The optical measuring camera transmits the measurement data to the calculation software, which uses algorithms to compare the measurement data with the original digital model. Any out-of-tolerance results are displayed on the system so that operators can develop improvement plans. Simultaneously, the test results are synchronized to the company's QMS system via an IoT system.

[0043] In an optional implementation, the two protective nets 500 form two inlets and outlets 700, with each of the frame fixing components 300 corresponding to one inlet and outlet 700.

[0044] In some embodiments, the workstation body is provided with two protective nets 500, and also with a control system 900 and a display system 800 capable of displaying measurement results, etc.

[0045] The optical inspection workstation provided by this utility model has a six-axis robot 100 mounted on its main body, and an optical measuring camera 200 mounted on the six-axis robot 100. The six-axis robot 100 uses the optical measuring camera 200 to measure the vehicle frame. A vehicle frame fixing component 300 is set on each side of the six-axis robot 100 to fix the vehicle frame. When the six-axis robot 100 is measuring the vehicle frame on one vehicle frame fixing component 300, the other vehicle frame fixing component 300 is used to replace the vehicle frame to be measured. The two vehicle frame fixing components 300 work together to improve measurement efficiency. The entire measurement process is controlled by the six-axis robot 100, which reduces the influence of human factors and improves the accuracy and stability of the measurement.
