[0023] In order to improve the measurement efficiency, a frame fixing assembly 300 is provided on both sides of the six-axis robot 100. The frame fixing assembly 300 is used to fix the frame. When the six-axis robot 100 measures the frame on one frame fixing assembly 300, the other frame fixing assembly 300 fixes the frame to be measured, thereby enabling the six-axis robot 100 to alternately measure the frames on the two frame fixing assemblies 300, thereby improving the measurement efficiency.

[0024] The front fixing assembly 301 and the rear fixing assembly 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 the frame needs to be fixed on the frame fixing assembly 300, the support shaft 3024 is inserted into the five-way bracket of the frame, and the frame is placed on the front support platform 3011; the downward pressure cylinder 3012 causes the downward pressure rod 3016 to move downward and press the frame downward; that is, the downward pressure rod 3016 cooperates with the front support to achieve the fixation of the frame in the upper and lower directions.

[0026] After the support shaft 3024 is inserted into the five-way bracket of the frame, the rotary cylinder 3021 rotates the rotary fixing member 3022 and applies pressure to the five-way bracket of the frame, thereby fixing 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, and both the upper fixing arm 30221 and the lower fixing arm 30222 have fixed columns, and the fixed columns are used to abut against the five-way bracket of the frame.

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

[0029] The two fixing columns apply external force to the bottom bracket, thereby keeping the support shaft 3024 inserted in the bottom bracket, so that the frame can be firmly fixed on the frame fixing assembly 300 . In an optional embodiment, a detection arm 3013 is provided on the downward pressure cylinder 3012, and a detection sensor 3015 is provided on the detection arm 3013.

[0030] In some embodiments, a detection arm 3013 is provided at the movable end of the downward pressure cylinder 3012, and a detection sensor 3015 is provided on the detection arm 3013; the detection sensor 3015 rises and falls with the movable end of the downward pressure cylinder 3012, and the detection sensor 3015 can detect whether the frame is placed, to avoid the frame not being placed, which causes the downward pressure rod 3016 to drop excessively.

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

[0032] A mounting arm 3014 is provided on the detection arm 3013, and a 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 of 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 vehicle 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 five-way bracket of the frame, the frame abuts against the support surface of the rear support platform 3023; and the rotating fixing member 3022 applies pressure to the frame to keep the frame abutting against the support surface, thereby ensuring the fixation of the frame.

[0035] Reference Figure 1 and Figure 3 In an optional embodiment, an auxiliary bracket 400 is further included, and the auxiliary bracket 400 is arranged 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 five-way 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 embodiment, two safety monitoring components 600 are further included, and one safety monitoring component 600 is respectively provided on both sides of the first direction of the workstation body; The first direction is a direction from one vehicle frame fixing assembly 300 to another vehicle frame fixing assembly 300 .

[0038] In order to ensure that there are no workers near the six-axis robot 100 when it is measuring, each frame fixing component 300 corresponds to a safety monitoring component 600; so that when the safety monitoring component 600 is turned on, the six-axis robot 100 will only perform measurement work if no workers are detected; and the safety monitoring component also has an alarm function.

[0039] The safety monitoring component 600 may be a grating sensor, a light curtain sensor, or an infrared radiation sensor, etc., according to the prior art.

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. The staff places the measured frame on the product positioning benchmark with the established coordinate system. The six-axis articulated arm robot grabs the optical measurement camera to take pictures and samples of the measured workpiece points. The entire measurement process is controlled by a PLC control system and no human participation is required. The optical measurement camera transmits the measured data to the calculation software, which compares the measurement data with the original digital model through an algorithm, and announces the out-of-tolerance results through the display system so that the operator can make improvement plans. At the same time, the inspection results will also be synchronized to the company's QMS system through the Internet of Things system.

[0042] In an optional embodiment, the two protective nets 500 form two inlets and outlets 700 , and each frame fixing assembly 300 corresponds to one inlet and outlet 700 .
