Description

Technical Field

[0001] The utility model relates to a detection device, in particular to an online detection device for BOPET production casting sheets. Background Art

[0002] BOPET cast sheet is an intermediate product in the production of biaxially oriented polyester film. In the BOPET film production process, the raw polyester chips are first dried and then extruded through an extruder in a molten state into a melt. This melt is then rapidly cooled and cast into thick sheets, forming the so-called "cast sheet."

[0003] During the casting of BOPET sheets, cameras are used to capture images of the sheets and transmit them to the backend for surface defect detection to reduce the risk of defective products. Because the camera equipment is exposed, fumes are generated during the unloading process after hot pressing. These fumes contain various components, such as water vapor and carbon dioxide, which can affect the accuracy of camera images. Furthermore, acidic gases and particulate matter in the fumes can corrode or contaminate the camera's optical components, affecting their long-term stability and accuracy. Utility Model Content

[0004] In response to the above problems, the present invention proposes an online detection device for BOPET production castings, which is used to solve the shortcomings of existing online detection devices.

[0023] Track plates 5 are provided on both sides of the shield 3, and the track plates 5 are fixedly connected to the shield 3. A sliding seat 6 is provided on the side of the track plate 5 away from the shield 3, and the sliding seat 6 is slidably connected to the track plate 5. A suction pipe is provided on the side of the sliding seat 6 away from the track plate 5, and the suction pipe extends to both sides directly in front of the lens end of the camera unit 1; in the process of taking pictures of BOPET castings, the smoke generated when the BOPET castings are discharged after hot pressing will be drawn away by the suction pipe after passing in front of the lens end of the camera unit 1, so that the smoke will not directly contact the lens end of the camera unit 1, thereby improving the effect of taking pictures and protecting the camera unit 1 at the same time.

[0024] A positioning plate 9 is provided above the shield 3. The two ends of the positioning plate 9 are detachably connected to the two sliding seats 6. An adjustment component is provided at the upper end of the shield 3 for pushing the positioning plate 9 to move horizontally. By pushing the positioning plate 9, the adjustment component can adjust the front and rear position of the suction pipe, which is more flexible.

[0025] Regarding the adjustment components:

[0026] The adjustment assembly includes an electric push rod 11, which has a mounting end and an output end. The mounting end of the electric push rod 11 is equipped with a mounting bolt 12, which is threadedly connected to a bolt hole opened at the upper end of the shield 3. The output end of the electric push rod 11 is fixedly connected to the positioning plate 9. The left and right position movement of the positioning plate 9 is controlled by the electric push rod 11. When the positioning plate 9 moves, the two sliding seats 6 fixed to the positioning plate 9 also move accordingly, thereby adjusting the front and rear position of the suction pipe.

[0027] Regarding suction pipe fittings;

[0028] The suction pipe assembly includes a bellows 7, a suction nozzle 8, and a negative-pressure duct connector 13. The suction nozzle 8 and negative-pressure duct connector 13 are fixedly connected to each end of the bellows 7. The negative-pressure duct connector 13 is fixedly connected to the side of the sliding seat 6 facing away from the track plate 5. The negative-pressure duct connector 13 is connected to an external negative-pressure dust extraction device via an external pipe. Under the influence of negative pressure, the smoke directly in front of the camera unit 1 is drawn into the bellows 7 by the suction nozzle 8 and then into the dust extraction device for treatment. Because negative-pressure dust extraction devices are commonly used in dust removal systems, their specific structure will not be described in detail here.

[0029] Regarding the detachable connection between the positioning plate 9 and the sliding seat 6, please refer to the following description.

[0030] The upper end of the positioning plate 9 is equipped with two positioning bolts 10, which pass through the positioning plate 9 and are threadedly connected to the positioning holes 17 opened on the upper end of the sliding seat 6. When the sliding seat 6 is removed from the lower end of the positioning plate 9, the positioning bolts 10 on the upper end of the positioning plate 9 can be unscrewed from the positioning holes 17 on the upper end of the sliding seat 6.

[0031] It is worth noting that a T-shaped groove 15 is provided on the side of the track plate 5 away from the protective cover 3, and a T-shaped slider 16 is provided on the side of the sliding seat 6 facing the track plate 5. The T-shaped slider 16 is inserted into the T-shaped groove 15 from both ends of the track plate 5. The T-shaped slider 16 is slidably connected to the T-shaped groove 15. A limit plate 14 is provided on one end of the T-shaped groove 15, and the limit plate 14 is fixedly connected to the T-shaped groove 15.

[0032] After releasing the fixing between the sliding seat 6 and the positioning plate 9, push the sliding seat 6 toward the end of the track plate 5 away from the limit plate 14, and then pull the T-shaped slider 16 out of the T-shaped slot 15. The sliding seat 6 and the suction pipe can be completely removed. The plug-in assembly method makes it easy for the staff to replace the suction pipe.

[0033] As a better implementation method of this embodiment:

[0034] A BOPET production cast sheet online detection device includes a camera unit 1, an adjustment bracket 2 is provided at the lower end of the camera unit 1, a shield 3 is provided at the upper end of the camera unit 1, and the shield 3 is detachably connected to the adjustment bracket 2.

[0035] Track plates 5 are provided on both sides of the shield 3, and the track plates 5 are fixedly connected to the shield 3. A sliding seat 6 is provided on the side of the track plate 5 away from the shield 3, and the sliding seat 6 is slidably connected to the track plate 5. A suction pipe is provided on the side of the sliding seat 6 away from the track plate 5, and the suction pipe extends to both sides directly in front of the lens end of the camera unit 1.

[0036] A positioning plate 9 is provided above the shield 3 , and both ends of the positioning plate 9 are detachably connected to the two sliding seats 6 . An adjusting component for pushing the positioning plate 9 to move horizontally is provided at the upper end of the shield 3 .

[0037] It is further explained that the shield 3 is sleeved on the upper half of the camera unit 1 , and multiple fixing bolts 4 are assembled on both sides of the shield 3 . The fixing bolts 4 pass through the shield 3 and are threadedly connected to the thread grooves opened on both sides of the camera unit 1 .

[0038] In this embodiment, the shield 3 is fixed to the camera unit 1 by a bolt connection. When replacing the shield 3, the fixing bolt 4 is unscrewed from the threaded groove on the outside of the camera unit 1 to remove the shield 3 and all components mounted on it, allowing for flexible assembly and disassembly.

[0039] How this application works:

[0040] The camera unit 1 is fixed to one side of the production line by adjusting the bracket 2. The lens end of the camera unit 1 faces the output position of the BOPET casting sheet, and is used to take pictures of the casting sheet and transmit them to the background for surface defect detection.

[0041] During the process of photographing BOPET casting sheets, the smoke generated when the BOPET casting sheets are discharged after hot pressing will be extracted by the suction pipe after passing directly in front of the lens end of the camera unit 1, so that the smoke will not directly contact the lens end of the camera unit 1, thereby improving the photographic effect and protecting the camera unit 1 at the same time.

[0042] The adjustment component pushes the positioning plate 9 to adjust the front and rear positions of the suction pipe to meet work requirements in different scenarios.
