The vibration damping devices 15 are used to reduce the vibration when the lens module 11 moves left and right. A supplementary lighting device 16 is arranged in the middle of the front of the vibration damping device 15. The supplementary lighting device 16 is used to increase the light source when the lens module 11 takes pictures.

[0025] Working principle: Install the housing 1 on the lifter. The lifter drives the housing 1 to move downward. The housing 1 drives the slider 2 to move downward. The slider 2 drives the vertical bar 3 to move downward. The vertical bar 3 moves downward to above the conveyor line. The vertical bar 3 is used to limit the tinplate cans on the conveyor line.

[0026] Please refer to Figures 1 - 10 , on the basis of the above embodiment, in another embodiment of the present invention, the vibration damping device 15 includes a square plate 151. The square plates 151 are respectively fixed at the bottoms of the mutually remote sides of the Y-shaped frame 14. A slide rod 152 is respectively embedded in the middle of the mutually remote sides of the square plates 151. Ring straight frames 153 are fixed on both sides of the front of the U-shaped frame 7. The inner wall of the ring straight frame 153 is in sliding contact with the outer wall of the slide rod 152. Circular plates 154 are fixed at the mutually remote ends of the slide rods 152. A spring 155 is arranged between the circular plate 154 and the ring straight frame 153. The spring 155 is sleeved on the slide rod 152. While the Y-shaped frame 14 drives the main unit 10 to move left and right reciprocally, the Y-shaped frame 14 drives the square plate 151 to move left and right reciprocally. The square plate 151 drives the slide rod 152 to move left and right reciprocally. The slide rod 152 moves left and right reciprocally in the ring straight frame 153. The slide rod 152 drives the circular plate 154 to move left and right reciprocally. The circular plate 154 drives the spring 155 to move left and right reciprocally. The spring 155 starts to reciprocally stretch and contract. Under the elastic force of the spring 155, the amplitude of the main unit 10 during left and right movement is reduced, thereby avoiding the problem that when the continuous non-stop sealing detection device is in use, the strong amplitude generated during the left and right movement of the main unit 10 causes the lens module 11 on the main unit 10 to take blurred pictures.

[0027] On the outer walls of the sliding rods 152, an inclined plate 156 is respectively fixed. The inclined plate 156 is located on the side where the square plates 151 are far away from each other. On the front of the inclined plate 156, a horizontal plate 157 is fixed. In the middle of the back of the horizontal plate 157, a T-shaped plate 158 is fixed. The back of the T-shaped plate 158 is fixedly connected to the bottom of the front of the main machine 10. The T-shaped plate 158 is used to support the lower part of the main machine 10. While the square plate 151 drives the sliding rod 152 to move left and right reciprocally, the sliding rod 152 drives the inclined plate 156 to move left and right reciprocally, the inclined plate 156 drives the horizontal plate 157 to move left and right reciprocally, the horizontal plate 157 drives the T-shaped plate 158 to move left and right reciprocally, and the T-shaped plate 158 supports the lower part of the main machine 10 to move left and right reciprocally, improving the stability when the lower part of the main machine 10 moves and reducing the jitter of the lower part of the main machine 10. Thus, when the continuous non-stop sealing detection device is in use, the problem that the shooting effect is poor due to the violent jitter of the lower part of the main machine 10 during movement is avoided.

[0028] The supplementary lighting device 16 includes an L-shaped plate 161. The L-shaped plate 161 is fixed in the middle of the front of the horizontal plate 157. At the bottom of the back of the L-shaped plate 161, a bottom plate 162 is fixed. One end of the bottom plate 162 far away from the L-shaped plate 161 is fixedly connected to the bottom surface of the horizontal plate 157. At the bottom of the front of the L-shaped plate 161, an annular frame 163 is fixed. Inside the inner wall of the annular frame 163, a supplementary light lamp 164 is fixed. The supplementary light lamp 164 is located above the sheet plate 4. While the inclined plate 156 drives the horizontal plate 157 to move left and right reciprocally, the horizontal plate 157 drives the L-shaped plate 161 to move left and right reciprocally, the horizontal plate 157 drives the bottom plate 162 to move left and right reciprocally, the bottom plate 162 supports the L-shaped plate 161 to move left and right reciprocally, the L-shaped plate 161 drives the annular frame 163 to move left and right reciprocally, and the annular frame 163 drives the supplementary light lamp 164 to move left and right reciprocally. The operator turns on the supplementary light lamp 164, and the supplementary light lamp 164 illuminates the seal of the tinplate can, enabling the supplementary light lamp 164 to follow the lens module 11 for shooting, making the seal of the tinplate can brightly visible. Thus, when the continuous non-stop sealing detection device is in use, the problem that the seal detection of the tinplate can is inaccurate due to insufficient light on the seal of the tinplate can is avoided.

[0029] On the top surface of the L-shaped plate 161, a return-shaped frame 165 is fixed. At the top of the back of the return-shaped frame 165, a round shell 166 is fixed. Inside the round shell 166, a temperature control module is arranged. On the back of the round shell 166, a semiconductor refrigeration plate 167 is fixedly installed. The semiconductor refrigeration plate 167 is located in front of the main machine 10. While the L-shaped plate 161 drives the annular frame 163 to move left and right reciprocally, the L-shaped plate 161 drives the return-shaped frame 165 to move left and right reciprocally, the return-shaped frame 165 drives the round shell 166 to move left and right reciprocally, and the round shell 166 drives the semiconductor refrigeration plate 167 to move left and right reciprocally. The operator turns on the semiconductor refrigeration plate 167 through the temperature control module in the round shell 166, enabling the semiconductor refrigeration plate 167 to cool down the main machine 10. Thus, when the continuous non-stop sealing detection device is in use, the problem that the main machine 10 is overheated and damaged due to too high temperature during continuous operation is avoided.
