[0043] Through the arrangement of the rotating assembly 13, after the tube jig 121 is rotated to the detection station by the rotating disc 12, the first sliding driving part 133 drives the second support 132 to drive the driving seat 134 to move towards the detection station until the clamping rod 1211 on the tube jig 121 is embedded into the clamping notch 137 on the clamping plate 136, realizing the clamping cooperation between the clamping part and the clamping part, so as to realize the temporary connection between the driving seat 134 and the tube jig 121 by the clamping cooperation between the clamping part and the clamping part; then the second rotary driving part 135 drives the driving seat 134 to drive the tube jig 121 located at the detection station and the packaging bottle sleeved on the tube jig 121 to rotate, which is conducive to the detection camera 21 to capture and obtain the pattern information of the packaging bottle body more comprehensively, reducing the generation of detection dead angles.

[0044] In actual use, the tube jig 121 can be adjusted according to the specifications of the packaging bottle, so that the packaging bottle is sleeved on the tube jig 121 with proper interference fit, so that the tube jig 121 can better drive the packaging bottle to rotate when rotating. The end of the tube jig 121 away from the rack 11 is chamfered, which facilitates the packaging bottle to be easily sleeved on the tube jig 121, thereby reducing the installation difficulty of the packaging bottle.

[0045] Referring to Figure 2 andFigure 4 The rack 11 is further provided with a pre-positioning assembly 14, which comprises a positioning station and a positioning part. The positioning station is located on the rotating path of the pipe-positioning jig 121 and is arranged before the detection station.

[0047] The positioning driving member is used to drive the pipe-positioning jig 121 at the positioning station to rotate. The positioning driving member comprises a support block 142, which is located on the side of the positioning rod 141 away from the positioning station. The support block 142 is obliquely supported on the rack 11 by a limiting member. The oblique upper end of the support block 142 is arranged close to the positioning station, and the oblique lower end of the support block 142 is arranged away from the positioning station.

[0049] When the pipe position jig 121 is positioned by the positioning assembly, the piston rod of the limiting air cylinder 146 is driven to retract, so that the inclined upper end of the supporting block 142 drives the driving wheel 145 to swing towards the positioning station under the action of the spring ejector pin 147, until the driving wheel 145 at the inclined upper end of the supporting block 142 abuts against the end of the pipe position jig 121 on the detection station; the first connecting shaft 143 drives the driving wheel 145 on the second connecting shaft 144 to rotate by the third rotary drive, and the pipe position jig 121 is driven to rotate by the rotating driving wheel 145, until the clamping rod 1211 on the pipe position jig 121 overlaps the upper part of the positioning rod 141, completing the positioning of the pipe position jig 121. Then the piston rod of the limiting air cylinder 146 is driven to extend, so as to drive the supporting block 142 to swing and drive the driving wheel 145 away from the pipe position jig 121, so as to facilitate the subsequent rotation of the turntable 12 to transfer the positioned pipe position jig 121 from the detection station to the detection station.

The upper lamp holder 22 is provided with an observation port 221, and the observation port 221 is oppositely arranged with the detection camera 21, so that the detection camera 21 can obtain the pattern of the bottle body on the detection station through the observation port 221. A plurality of lamp tubes are installed on the bottom of the upper lamp holder 22, and in the subsequent detection process, the detection station can be illuminated by the plurality of lamp tubes on the upper lamp holder 22, so that the detection camera 21 can more clearly obtain the pattern information.

[0052] The detection support bottom is further connected with a lateral lamp holder 23, and a lateral lamp 231 is installed on the lateral lamp holder 23. The lateral lamp 231 is arranged towards the detection station, and the lateral lamp 231 cooperates with the lamp tube on the upper lamp holder 22 to illuminate the detection station, which is beneficial to further improve the illumination effect of the detection station.

[0053] The implementation principle of the embodiment of the present application is that: after the to-be-detected packaging bottles are sequentially sleeved on the plurality of pipe site jigs 121 of the turntable 12, the first rotary driving member drives the turntable 12 to drive the pipe site jigs 121 to rotate. During the rotation of the pipe site jigs 121 with the turntable 12, the pipe site jigs 121 first enter the positioning station and are positioned by the positioning part of the pre-positioning assembly 14, and then enter the detection station. While the pipe site jigs 121 are driven to rotate by the rotating assembly 13, the detection camera 21 on the detection station acquires the pattern information on the packaging bottles sleeved on the pipe site jigs 121 and feeds back to the controller. The controller judges whether the printing pattern of the packaging bottle is qualified, realizes the automatic detection of the printing pattern of the packaging bottle body, and is beneficial to improve the detection efficiency of the printing pattern of the packaging bottle body.
